DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the embodiments of the present application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments.

[0029] The embodiment of the present application provides a technical solution to construct a dental unit for auxiliary cleaning for people (especially children) who find it difficult to use a traditional toothbrush. Figure 1 and Figure 2 A peristaltic toothbrushing device comprises a shell 1, a two-position three-way water valve 2 installed in the shell 1, a gas-liquid separation box 5 and a first air pump 6, a brush head 13 is arranged on one side of the shell 1, a five-way pipe 4 is connected between the brush head 13 and the two-position three-way water valve 2, the gas-liquid separation box 5 and the first air pump 6, a peristaltic pump 3 is installed in the pipeline connecting the two-position three-way water valve 2 and the brush head 13, and a mixed liquid for cleaning teeth is delivered to the brush head 13, one end of the gas-liquid separation box 5 is equipped with a second air pump 8, and the other end is connected to the brush head 13, the second air pump 8 outputs negative pressure to the brush head 13 side through the gas-liquid separation box 5, and the first air pump 6 is connected to the brush head 13, and outputs positive pressure to the brush head 13 side.

[0030] In an actual working environment, in order to adapt to the actual output airflow form (the difference between positive pressure and negative pressure), the first air pump 6 uses a DC air pump and the second air pump 8 uses a vacuum pump.

[0031] The cleaning effect of the present application on teeth is achieved as follows: first, the child presses the brush head 13 onto the upper gum. Since the first delivery port 200 and the second delivery port 201 are provided on the two-position three-way water valve 2, the first delivery port 200 introduces cleaning liquid, and the second delivery port 201 introduces clean water, which are mixed in the two-position three-way water valve 2. The mixed liquid obtained after mixing is delivered to the gap between the brush head 13 and the upper gum under the action of the peristaltic pump 3. At the same time, the first air pump 6 and the second air pump 8 are started to output positive pressure and negative pressure to one side of the brush head 13, that is, to generate blowing and suction effects in the above-mentioned gap. Under this action, the soft brush head 13 will adhere to the surface of the teeth and peristalsize. Combined with the flushing of the mixed liquid, the simulation of the brushing action is completed to remove the stains adhering to the teeth, and then the removed stains are mixed into the mixed liquid. The liquid becomes sewage. Due to the negative pressure generated by the second air pump 8, the sewage is sucked into the gas-liquid separation box 5. When the sewage is completely sucked out and no longer remains in the oral cavity, since the first air pump 6 is connected to the second extension pipeline, the connecting pipeline of the second air pump 8 and the gas-liquid separation box 5 is connected to the first air pump 6. The first air pump 6 outputs positive pressure to the gas-liquid separation box 5 through the second extension pipeline. The second extension pipeline is provided with a second air valve 9 to control the first air pump 6 to supply air to the gas-liquid separation box 5. The first air pump 6 outputs positive pressure to the gas-liquid separation box 5 through the second extension pipeline. This positive pressure will drive the gas-liquid separation box 5 to perform gas-liquid separation, and the liquid (i.e. the sewage adsorbed in the above-mentioned process) sinks and is squeezed into the sewage box 12 by the positive pressure. Finally, after a certain amount of sewage is accumulated, the sewage box 12 is separated from the shell 1 and the sewage is poured out.

[0032] The above takes the cleaning of the upper gums as an example, however, a complete auxiliary cleaning action also includes the cleaning of the lower pressing bed. When using the present application to clean the lower pressing bed, it is only necessary to turn the brush head 13 upside down on the lower pressing bed, and the rest of the action process is the same as above.

[0033] In the implementation of this application, in order to realize automatic control of the gas circuit and water circuit, the following further settings are made:

[0034] A first water valve 10 is provided on the connecting pipeline between the gas-liquid separation box 5 and the brush head 13 to control the conduction of sewage to the gas-liquid separation box 5;

[0035] A sewage box 12 is detachably installed in the housing 1, and the sewage box 12 is connected to the gas-liquid separation box 5. A second water valve 11 is provided on the connected pipeline to control the conduction of sewage to the sewage box 12;

[0036] A first air valve 7 is provided on the connecting pipeline between the second air pump 8 and the brush head 13, which controls the second air pump 8 to deliver air to the oral cavity through the brush head 13, so as to loosen the fit of the brush head 13 on the teeth. At the same time, due to the connection of the five-way pipe 4, the mixed liquid is pushed to flow in the same conveying direction;

[0037] The first air pump 6 is connected to a second extension pipeline, and the connecting pipeline between the second air pump 8 and the gas-liquid separation box 5 is connected to the first air pump 6. The first air pump 6 outputs positive pressure to the gas-liquid separation box 5 through the second extension pipeline. A second air valve 9 is provided on the second extension pipeline to control the first air pump 6 to supply air to the gas-liquid separation box 5 to squeeze the sewage out of the gas-liquid separation box 5.

[0038] Furthermore, the brush head 13 is U-shaped, and a brush handle 14 is installed on one side of the brush head 13 connected to the five-way tube 4. The U-shaped setting of the brush head 13 can better fit the gums, and the setting of the brush handle 14 makes it convenient for children to hold the brush head 13 when using it and change the direction of the brush head 13.

[0039] A flow control meter is provided in the connection passage between the first delivery port 200, the second delivery port 201 and the two-position three-way water valve 2. The first delivery port 200 is used to deliver the cleaning liquid, and the second delivery port 201 is used to deliver the clean water. The flow control meter controls the ratio of the cleaning liquid to the clean water during the mixing process, and replenishes the cleaning liquid and the clean water in time when the amount of the cleaning liquid and the clean water is insufficient.

[0040] By adjusting different modes, the oral mode of changing coefficients can be achieved, which specifically include gentle mode, standard mode and enhanced mode. Each mode is changed by adjusting the peristaltic extrusion force of the brush head 13, and the peristaltic extrusion force of the brush head 13 is directly affected by the air delivery and suction effects generated by the cooperation of the second air pump 8 and the first air pump 7. Different airflow delivery rates are obtained by adjustment, and the adjustment and switching corresponding to different modes, the gentle mode, standard mode to enhanced mode are changed from low to high according to the airflow delivery rate.

[0041] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
