A teeth cleaning method which cleans the teeth using a nozzle (111) that sets a dental floss (112) inside including: the pulsating water flow (120) is input from one end of the nozzle (111) and ejected from the water-spraying opening (116) at the other end of the nozzle; meanwhile, the pulsating water flow (120) pushes the piston (114) within the nozzle (111) to move, which drives the dental floss (112) fixed to the piston (114) at one end to move toward the water-spraying opening (116) direction; the piston and dental floss are pushed to the original position by a return spring (113) whose top is against the piston (114) during intermittent period of pulsating water flow (120), so that the dental floss (112) and pulsating water flow (120) move synchronously on the teeth surface and the periodontal tissue in every movement cycle.

Description

Method for cleaning teeth

The present invention relates to a method of cleaning teeth, and more particularly to a technique for reciprocating movement of a floss driven by a pulsed water column. Background technique

Flossing and water rushing are accepted by more and more people, and are gradually becoming a must-have for everyday households. At present, in the application of dental care at home and abroad, in addition to toothbrushes, flossing and water rushing are also the most widely used tools for cleaning teeth. The floss can effectively remove the food residue stuck in the teeth, and can also scrape the tooth spots on the abutting surface of the tooth, but the floss is inconvenient, unsanitary, and has no dead angle. Water rushing uses pulsed water to remove the residue from the periodontal, and it also has the effect of massage, but it cannot replace the function of the floss. Summary of the invention

The technical problem to be solved by the present invention is to propose a method of cleaning teeth, which combines the advantages of flossing and water rushing.

In an embodiment of the invention, a floss chamber is disposed in the nozzle, the piston is disposed at one end of the floss chamber, one end of the floss is fixed to the piston, and the other end is passed through the floss chamber to the nozzle.

In an embodiment of the invention, one end of the return spring abuts against the piston and the other end abuts against a step in the floss chamber.

In an embodiment of the invention, the pulse water column has a frequency of 10-20 Hz.

In an embodiment of the invention, the pulsed water column is generated by electromagnetic pump actuation. In an embodiment of the invention, the pulsed water column is generated by motor drive.

The method for cleaning teeth of the invention uses a pulse water column to drive the dental floss to reciprocate between the tooth surface, the periodontal and the interdental joint, to remove the food residue and stones between the interdental joints, and has the dual functions of water washing and flossing, which is convenient. Hygiene does not leave a dead end. BRIEF abstract

BEST MODE FOR CARRYING OUT THE INVENTION

Briefly, embodiments of the present invention describe a dental cleaning technique in which a floss is reciprocated under a pulsed water column and applied to the flank and periodontal. The technology uses a pulsed water column to drive the floss to reciprocate between the tooth surface, the periodontal and the interdental joint, to remove the food residue and stones between the interdental joints, and has the dual functions of water washing and flossing, which is convenient for hygiene without leaving a dead angle. .

1 is an external view of a scaler used in a method of cleaning teeth according to an embodiment of the present invention. Fig. 2 is a cross-sectional structural view of a scaler used in a method of cleaning teeth according to an embodiment of the present invention. Referring first to Figures 1 and 2, the scaler 100 includes a handle 101 and a dental function assembly 1 10. The handle 101 serves as the main body of the dental appliance, and the dental function assembly 1 10 can be attached to or detached from the handle 101. Dental cleaning function Component 1 10 can be a nozzle functional component.

The power button 103 and the function button 102 are provided on the surface of the handle 101. Within the handle 101 are provided a PCB control board 105, a battery 104, a power receiving assembly 106, an electromagnetic pump 107 and a charger. The charger is a separate module. The power receiving component 106 preferably uses a connectionless charging coil. The charging coil is, for example, AP 1201 manufactured by Artco.

4 is a block diagram showing the structure of a scaler control module according to an embodiment of the present invention. Referring to FIG. 3, the control module of the embodiment is disposed on the PCB control board 105, and includes a voltage conversion module 123, a button module, an embedded processor module 121, a driving module 122, and an electromagnetic pump 107 for controlling each dental function group. How the pieces work.

As the core of the control module, the embedded processor module 121 can be used with ATMEL's industrial-grade embedded processor ATmega48.

The voltage conversion module 123 can convert the 3.7V of the battery into 3.3V required by the embedded processor module 121, convert the 3.7V of the battery into 5V required by the driving module 122, and convert the 3.7V of the battery into 107 Need 12V or 24V.

The drive module 122 is coupled to the electromagnetic pump 107 for driving the operation of the electromagnetic pump 107. The electromagnetic pump 107 is used to drive the functional components of the dental appliance, such as the functional components of the nozzle. In other embodiments, the electromagnetic pump 107 can be replaced with a motor.

The button module can include a power button 103, a function adjustment button 103 that is coupled to the embedded processor module 121.

3 is a structural view of a dental cleaning functional component used in a method of cleaning teeth according to an embodiment of the present invention. Referring to Figure 3, the dental functional assembly 110 includes a spout 111, a floss 112, a return spring 113, a piston 114, and a floss chamber 115. The nozzle 111 is a pipe into which the pulse water column 120 enters and is ejected. The pulse water column 120 enters from one end (left end in the figure) of the nozzle 111 and is ejected from the nozzle 116 at the other end (the right end in the drawing). A floss chamber 115 is disposed in the nozzle 111, and a piston 114 is disposed at one end of the floss chamber 115. The end of the floss 112 is fixed to the piston, and the other end passes through the floss chamber 115 to reach the nozzle 116 of the nozzle. A return spring 113 is also provided in the floss chamber 115, one end of which abuts against the piston 114 and the other end which abuts against a step 117 in the cavity 115. The floss chamber 115 is used to store the floss 112 in an initial state.

The method of cleaning teeth of the present invention is as follows:

The pulsed water frequency can be between 10 and 20 Hz, driven by electromagnetic waves 107. When the pulsed water column enters the nozzle 112, the piston 114 is driven by the pulsed water column in the nozzle and drives the floss forward. At this time, the floss 112 can move forward along the entire nozzle 111, and its end can protrude from the nozzle 116 and act on the tooth surface and the periodontal. During the intermittent pulse water column, the return spring 113 can push the piston back to bring the floss 112 back to its original position.

Therefore, in each action cycle, the floss can reciprocate and act on the tooth surface and the periodontal to remove the food residue and stones between the teeth, and have the dual functions of water washing and flossing, which is convenient for hygiene. There is no dead corner. Because the pulse water frequency can reach 10 to 20 Hz, the efficiency of flossing the tooth surface and periodontal is greatly improved, which makes it possible for patients with orthodontic and prosthetic bridges to use flossing.

While the present invention has been described in its preferred embodiments, the present invention is not intended to be limited thereto, and the present invention may be modified and improved without departing from the spirit and scope of the invention. The scope of protection is defined by the terms of the claims.
