Form the quantity of the bristle of the 1st pieces 16a, can consider that bristle diameter and bristle thickness are suitably selected.Such as, in the 1st embodiment, preferably 20 ~ 28, more preferably 22 ~ 28.
In 1st pieces 16a, consider use sense, brush and sweep sense, cleaning effect or durability etc., many different for thickness bristles any combination can be used.
Beeline between the pieces 16a in the 1st pieces group 16, the distance namely from the central shaft of pieces 16a to the central shaft of adjacent pieces 16a, most weakness preferably 1.4 ~ 2.8mm, more preferably 1.7 ~ 2.5mm in group.
[the 2nd pieces group]
2nd pieces group 18 planting on hair side 12a at head 12, clamps the 1st pieces group 16, arranges a pair in the side, front end 13 of head 12 and rear end side.A pair the 2nd pieces groups 18 are separated from each other.That is, form the 2nd pieces 18a of a pair the 2nd pieces groups 18, be not set to the both sides of the width surrounding the 1st pieces group 16, but be set to the both sides surrounding its length direction.
Thus, by the 2nd pieces 18a not being set to the both sides of the width surrounding the 1st pieces group 16, make in a pair the 2nd pieces groups 18, the hair end of each 2nd pieces 18a easily enters the space with neck portion etc. between tooth.Consequently, due to the 2nd pieces group 18, the tartar existed in the space between tooth and neck portion etc. efficiently can be scanned out and is removed.
Form the 2nd pieces 18a of the 2nd pieces group 18, also can the middle section of planting hair side 12a of implanted head 12.
2nd pieces group 18 is formed, the bristle lengths of those many 2nd pieces 18a by implanting many second pieces 18a, is aligned in the bristle lengths higher than the 1st pieces group 16.Accordingly, the boundary member of the 1st pieces group 16 and the 2nd pieces group 18 defines difference in height.By the 1st pieces group 16 and the 2nd pieces group 18 height of formation poor, can efficiently to scan out between tooth and neck portion etc. space in the tartar that exists, thus tartar removing effect improves.
2nd pieces group 18 is to open wide the center direction of planting hair side 12a, the appearance that the 1st pieces group 16 surrounds in the longitudinal direction to be arranged each the 2nd pieces 18a and formed.Particularly, in this example, the 2nd pieces group 18 is to open wide the center direction of planting hair side 12a, by the appearance that the 1st pieces group 16 surrounds in the longitudinal direction, to be set to overlook in V shape.Herein, that " opens wide center direction " is meant to, 2nd pieces group 18 is not set to relative width direction parallel (straight line setting in the width direction), and in the 2nd pieces group 18, the pieces 18a being configured at the two ends of the width of planting hair side is configured in, than the position of pieces 18a closer to the center of middle section being configured at central authorities.Specifically be meant to, when observing head 12 from the side, there is the 1st pieces group 16 and the nonoverlapping in the longitudinal direction region of the 2nd pieces group 18, and the 1st pieces group 16 and the overlapping in the longitudinal direction region of the 2nd pieces group 18.When observing head 12 from the side, the width in the region that the 1st pieces group 16 and the 2nd pieces group 18 are overlapping in the longitudinal direction, preferred 0.0 ~ 3.0mm on every 1 described region.
In addition, in this example, the angle (interior angle of V shape) of the 2nd pieces group 18 of V shape is different from the angle that two articles of limits of the 2nd pieces group 18 side in the rhombus of the 1st pieces group 16 are formed.
In addition, the angle of the 2nd pieces group 18 of V shape, the angle formed with two articles of limits of the 2nd pieces group 18 side in the rhombus of the 1st pieces group 16 also can be identical.
2nd pieces group 18 as described above, by being configured to open wide the center direction of planting hair side 12a, surrounds the 1st pieces group 16, the dirts such as the tartar scanned out by the 2nd pieces group 18 in the longitudinal direction, and the middle body be easy to the width of the 2nd pieces group 18 is concentrated.Therefore, in the way scanned out by the 2nd pieces group 18, dirt can be suppressed to escape from from the both sides of the width of the 2nd pieces group 18, remain in the situation in the space of waiting between tooth.
In addition, in this example, each the 2nd pieces 18a of the 2nd pieces group 18, also comprises the 1st pieces 16a of the 1st pieces group 16, is set to the configuration of plover shape, but is not limited to such arrangement.
The spread geometry of the 2nd pieces group 18 is not limited to V shape, such as, also can be arc-shaped.
The spread geometry of the 2nd pieces group 18, because the effect scanned out by tartar with the space in neck portion etc. between tooth is better, preferred V shape.
In this example, in 1 the 2nd pieces group 18, often group 5, altogether 10 the 2nd pieces 18a are configured to two groups (two row) in the longitudinal direction.
The quantity forming the 2nd pieces 18a of the 2nd pieces group 18 is not limited to 10, can be less than 9, also can be more than 11.Form the quantity of the 2nd pieces 18a of the 2nd pieces group 18, the suitably settings such as the diameter of the 2nd pieces 18a can be considered, preferably 3 ~ 18, more preferably 5 ~ 10.
In addition, the 2nd pieces group 18 can be configured to one group (row) in the longitudinal direction by the 2nd pieces 18a and be formed, and also can be configured to more than three groups (more than three row) and is formed.
When 2nd pieces 18a is configured to multiple row, the bristle lengths that the bristle lengths of the pieces 18a of front or rear end side can be formed as the pieces 18a of the row than middle section side is longer.
The mode of a pair the 2nd pieces groups 18, in the scope not damaging effect of the present invention, can be asymmetric.That is, the 2nd pieces group 18 of front and the 2nd pieces group 18 of rear end side, in the scope not damaging effect of the present invention, can be multi-form.Being meant to of " symmetry " herein, with through plant the center of hair side 12a and the line drawn in the direction of the width for axle symmetrical (axial symmetry).
Such as, in the 2nd pieces group 18 of front and the 2nd pieces group 18 of rear end side, the quantity of the 2nd pieces 18a can be different, and the spread geometry of the 2nd pieces 18a also can be different.
In a pair the 2nd pieces groups 18, preferably the quantity of the 2nd pieces 18a, spread geometry are identical and symmetrical.
2nd pieces 18a, can do up many bristles and be formed.
As the bristle of formation the 2nd pieces 18a, being not particularly limited, can illustrating as enumerated in the 1st pieces 16a.
2nd pieces 18a can only be formed with taper hair, also can only be formed with half-cone hair, also can only be formed with straight shape hair, can also be combined to form by two or more in taper hair, straight shape hair, half-cone hair.2nd pieces 18a, the point that the removing effect of the tartar existed from the space between tooth and neck portion is higher, is preferably formed by taper hair.
The shape of cross section forming the bristle of the 2nd pieces 18a can be illustrated as enumerated in the 1st pieces 16a, circular.
In 2nd pieces 18a, consider use sense, brush and sweep sense, cleaning effect or durability etc., many different for thickness bristles any combination can be used.
2nd pieces 18a is preferably easier than the 1st pieces 16a to be bent.Accordingly, the hair end of the 2nd pieces 18a easily enters the space with neck portion between tooth, and the effect of tartar removing improves.
Suitably can set the quantity of the bristle of formation the 2nd pieces 18a, thus make the diameter of the 2nd pieces 18a be desired value.Such as, preferably 10 ~ 15, more preferably 11 ~ 14.
Beeline between the pieces 18a in the 2nd pieces group 18, the distance namely from the central shaft of pieces 18a to the central shaft of adjacent pieces 18a, at most weakness preferably 1.4 ~ 2.8mm, more preferably 1.8 ~ 2.2mm.
The distance of the 2nd pieces 18a and the 1st pieces 16a, that is, the distance from the central shaft of the 2nd pieces 18a to the central shaft of the 1st adjacent pieces 16a, preferably 1.5 ~ 4.0mm, more preferably 2.5 ~ 3.2mm.
[the 3rd pieces group]
3rd pieces group 20 plants in hair side 12a at head 12, the 1st pieces group 16 and a pair the 2nd pieces groups 18 clamping it is clamped from front and rear end side, is provided with a pair in the side, front end 13 of head 12 and rear end side.A pair the 3rd pieces groups 20 are separated from each other.That is, the 3rd pieces 20a forming a pair the 3rd pieces groups 20 is not configured to the appearance of the both sides of the both sides of the width surrounding the 1st pieces group 16 and the width of the 2nd pieces group 18.
Thus, by the appearance of the both sides of the width of the both sides and the 2nd pieces group 18 that are not configured to the width surrounding the 1st pieces group 16, identically with the 2nd pieces group 18, the hair end of each the 3rd pieces 20a easily enters the space with neck portion etc. between tooth, consequently, tartar removing efficiency improves.
Form the 3rd pieces 20a of the 3rd pieces group 20, also can the middle section of planting hair side 12a of implanted head 12.
3rd pieces group 20 is formed, the bristle lengths of those many 3rd pieces 20a by implanting many 3rd pieces 20a, is aligned in the bristle lengths higher than the 2nd pieces group 18.Accordingly, the boundary member of the 2nd pieces group 18 and the 3rd pieces group 20 defines difference in height.By the 2nd pieces group 18 and the 3rd pieces group 20 height of formation poor, can efficiently to scan out between tooth and neck portion etc. space in the tartar that exists, thus tartar removing effect improves.
3rd pieces group 20 is to open wide the center direction of planting hair side 12a, in the outside (front and rear end side) of the 2nd pieces group 18, by the appearance that the 1st pieces group 16 surrounds in the longitudinal direction, to arrange each the 3rd pieces 20a and formed.That is, the 3rd pieces group 20 is formed the appearance that the 1st pieces group 16 and the 2nd pieces group 18 surrounded in the longitudinal direction.Herein, that " opens wide center direction " is meant to, 3rd pieces group 20 is not set to relative width direction parallel (straight line setting in the width direction), and in the 3rd pieces group 20, the pieces 20a being configured at width two ends is configured in, than the position of pieces 20a closer to middle section side being configured at central authorities.Specifically be meant to, when observing head 12 from the side, there is the 2nd pieces group 18 and the nonoverlapping in the longitudinal direction region of the 3rd pieces group 20, and the 2nd pieces group 18 and the overlapping in the longitudinal direction region of the 3rd pieces group 20.
The width in the region that the 2nd pieces group 18 and the 3rd pieces group 20 are overlapping in the longitudinal direction, preferred 0.0 ~ 3.5mm on every 1 described region.
Particularly, in this example, the 3rd pieces group 20 is to open wide the center direction of planting hair side 12a, in the appearance that the 1st pieces group 16 surrounds by the outside (front and rear end side) of the 2nd pieces group 18 in the longitudinal direction, to be set to V shape.In addition, in this example, the angle of the 3rd pieces group 20 of V shape is identical with the angle of the 2nd pieces group 18.
In addition, the angle of the 3rd pieces group 20 of V shape, also can be different with the angle of the 2nd pieces group 18.
Like this, by the 3rd pieces group 20 being configured to open wide the center direction of planting hair side 12a, by the appearance that the 1st pieces group 16 surrounds at length direction, identical with the 2nd pieces group 18, dirt is difficult to flee from from the both sides of the width of the 3rd pieces group 20, and thus tartar removing effect improves.
In addition, in this example, each the 3rd pieces 20a of the 3rd pieces group 20, also comprises the 1st pieces 16a of the 1st pieces group 16 and the 2nd pieces 18a of the 2nd pieces group 18, is set to the configuration of plover shape, but is not limited to such configuration.
The spread geometry of the 3rd pieces group 20 is not limited to V shape, such as, also can be arc-shaped.
The spread geometry of the 3rd pieces group 20, because the effect scanned out by tartar with the space in neck portion etc. between tooth is better, preferred V shape.
In this example, in 1 the 3rd pieces group 20,5 the 3rd pieces 20a are configured to one group (row) in the longitudinal direction.
