The first embodiment is as follows:

referring to fig. 1 to 4, as shown in fig. 3, in one embodiment, the tooth washing device 100 includes a first reservoir 10, a tooth washing apparatus 20, a connector 30, a liquid feeder, a housing 50, an ozone generator 60, and a controller 70.

wherein the first reservoir 10 is disposed in the housing 50 for containing water to generate and store the tooth-washing liquid containing ozone through the ozone generator 60.

The tooth washing device 20 comprises a tooth washing device body 21 and a second liquid storage device 22 fixedly connected with the tooth washing device body 21.

Wherein the dental rinser body 21 comprises a shell, a switch 211 arranged on the shell, a pipette 212 inserted into the second reservoir 22, a rechargeable battery 213, a pipette 214, an ejector 215 and a power receiving terminal arranged at the bottom of the shell; wherein, the switch 211 is used for controlling the opening and closing of the liquid sucker 214; the pipette 212, the pipette 214 and the sprayer 215 are sequentially communicated to suck the tooth washing solution in the second reservoir 22 and to spray the tooth washing solution out by the sprayer 215. The power receiving terminal is electrically connected to the rechargeable battery 213.

The second reservoir 22 is engaged with the back of the tooth cleaner body 21 and is detachable from the tooth cleaner body 21. When the dental scaler 20 is used for tooth washing, the second reservoir 22 supplies a tooth washing solution to the scaler body 21. The second reservoir 22 comprises a tank body, a one-way valve 221 arranged at the bottom of the tank body, and an air inlet 222 and an air exhaust structure 223 arranged at the upper part of the tank body. The non-return valve 221 in the bottom of the can body is a known duck bill valve, but any other known non-return valve can be used, as long as it can be opened when the tooth cleaning solution is injected into the second reservoir 22. The air inlet hole 222 is used for sucking air when the second reservoir 22 delivers the tooth washing liquid to the tooth washing device body 21, and the opening of the air inlet hole 222 is small and has a diameter of about 0.5mm, so that the tooth washing liquid in the second reservoir 22 cannot flow out of the second reservoir 22 due to the surface tension and the atmospheric pressure of the tooth washing liquid. As shown in fig. 4, the exhaust structure 223 includes an exhaust channel 2231 having an exhaust hole 2232, a sliding rod 2233 not disposed in the exhaust channel 2231, a plug 2234 fixed to one end of the sliding rod 2233 for plugging the exhaust hole 2232, and an elastic member 2237 for driving the plug 2234 to plug the exhaust hole 2232, wherein the elastic member 2237 is a spring in this embodiment; wherein the exhaust hole 2232 is formed at an outer end of the exhaust channel 2231; a stopping wall 2235 is arranged at one end of the exhaust channel 2231 close to the interior of the tank body, and a through hole 2236 for air to enter and exit is further formed on the stopping wall 2235; the slide rod 2233 extends through the stop wall 2235; the elastic member 2237 is sleeved on the sliding rod 2233, and one end of the elastic member is abutted against the plug 2234, and the other end of the elastic member is abutted against the stop wall 2235.

the connectors 30 are disposed at a notch of the housing 50, and in this embodiment, there are two connectors 30, each of which takes the form of a connection seat, on which the tooth washing device 20 is placed. The connector 30 is provided with a liquid supply nozzle 31 and a charging terminal 32; wherein the liquid supply nozzle 31 communicates with the second reservoir 22 through the check valve 221 when the dental scaler 20 is coupled to the connector 30. And the charging terminal 32 is electrically connected to the power source to electrically connect to the rechargeable battery 213 through the power receiving terminal and charge the rechargeable battery 213 when the dental scaler 20 is placed on the connection socket. In this embodiment, the outer wall of the housing 50 also forms the side wall of the connector 30. On the side wall of the connector 30, as shown in fig. 4, there is provided an exhaust driving structure, in this embodiment, a protrusion 33.

In this embodiment, the liquid delivery device is a liquid pump 40 disposed in the housing 50 and below the first liquid reservoir 10, and is used for delivering the tooth cleaning liquid in the first liquid reservoir 10 to the liquid supply nozzle 31. The liquid inlet end of the liquid pump 40 is communicated with the first liquid reservoir 10 through a liquid pump water inlet channel 41; the liquid outlet end of the liquid pump 40 is communicated with the liquid supply nozzle 31 through a liquid pump water outlet passage 42.

The upper portion of the housing 50 is provided with a control panel 51, and the control panel 51 allows a user to control the tooth washing device 100 to turn on or off the tooth washing mode.

an ozone generator 60, the construction of which is also known, is disposed in the first reservoir for electrolyzing water to produce an ozone-containing tooth cleaning solution, and comprises a first electrode 61, a second electrode 62, and a noble metal polymer 63 disposed between the first electrode 61 and the second electrode 62.

The controller 70 comprises a pressure sensing module 71 and a control module 72, wherein the pressure sensing module 71 is arranged on the connecting seat and is used for detecting the pressure of the tooth washing device 20 on the connecting seat and sending the pressure to the control module 72; the control module 72 is electrically connected to the pressure sensing module, the charging terminal 32, the liquid feeder, the ozone generator 60, a power supply (not shown) and the control panel 51, and is used for controlling the on/off of the liquid feeder and the on/off of the ozone generator 60, and a BMS unit is provided for managing the charging of the rechargeable battery 213. In this embodiment, it should be noted that the control module 72 determines whether the second reservoir 22 is filled with the tooth cleaning solution according to the pressure of the tooth cleaning device 20 sent by the pressure sensing module 71 to the connection base, so as to control the liquid feeding device to be turned off.

The operation of the dental prophylaxis device 100 in this embodiment is as follows:

When the tooth washing is not performed, the tooth washing device 20 is placed on the connection socket of the connector 30, and the BMS unit of the control module 72 automatically controls the charging of the rechargeable battery 213, and more particularly, the power supply is electrically connected to the rechargeable battery 213 through the power receiving terminals and the charging terminals 32, which are in contact with each other. Meanwhile, the protrusion 33 on the side wall of the connector 30 is inserted into the vent hole 2232 to abut against the stopper 2234, so that the stopper 2234 is away from the vent hole 2232 against the outward elastic force of the elastic member 2237, and the inside of the second reservoir 22 is open to the atmosphere.

When washing teeth, the user firstly starts the tooth washing mode through the control panel 51, and the control module 72 controls the ozone generator 60 to start so as to electrolyze water to generate tooth washing liquid containing ozone. After the ozone generator 60 is started for a period of time set by a person, the control module 72 controls the liquid pump 40 to be started, the tooth-washing liquid in the first liquid storage device 10 is delivered to the second liquid storage device 22 through the liquid pump water inlet channel 41, the liquid pump 40, the liquid pump water outlet channel 42, the liquid supply nozzle 31 and the one-way valve 221, and at this time, the air in the second liquid storage device 22 is rapidly discharged through the air vent 2232, so that the second liquid storage device 22 is rapidly filled. After the second reservoir 22 is filled, the pressure sensing module 71 sends a signal to the control module 72, and the control module controls the liquid pump 40 to close after receiving the signal. At this time, the user can know that the tooth cleaner 20 is filled with the tooth cleaning solution, the user can take the tooth cleaner 20 out of the connecting seat, hold the tooth cleaner 20 by hand, press the switch 211 on the tooth cleaner body 21, the tooth cleaning solution outputs the tooth cleaning solution in the second reservoir 22 to the ejector 214 through the pipette 212 and the pipette 214, and the tooth cleaning solution is ejected from the ejector 214 to realize the tooth cleaning function.

In the first embodiment, since the tooth washing liquid containing ozone needs to be prepared before tooth washing, the ozone content can achieve the disinfection effect, the power of the electrolyzed water is high, the tooth washing liquid can not be directly prepared in the tooth washing device by the electrolyzed water, therefore, by providing the second reservoir 22 and allowing the second reservoir 22 to supply the tooth cleaning solution to the tooth cleaner body 21 during tooth cleaning, while the first reservoir 10 delivers the washing liquid to the second reservoir 22 through the liquid pump 40 when the dental scaler 20 is coupled to the connector 30, so that the generation and storage of the tooth washing liquid can be realized through the first reservoir 10, and the tooth washing liquid in the first reservoir 10 can be automatically injected into the second reservoir 22, so that the user can supply the tooth washing liquid from the second liquid reservoir 22 fixedly connected with the tooth washing device body 21 during tooth washing, thereby enabling the user to freely hold the tooth washing device, getting rid of the constraint of the hose and obtaining good use experience.

Example two:

the only difference between the dental prophylaxis device 100 of the second embodiment and the dental prophylaxis device 100 of the first embodiment is that the air venting structure 223 on the second reservoir 22 and the air venting actuating structure on the sidewall of the connector are different. Referring to fig. 5, as shown in fig. 5, in the second embodiment, the air discharging structure 223 on the second liquid storage 22 includes an air discharging channel 2231 having an air discharging hole 2232, a sliding rod 2233 slidably disposed in the air discharging channel 2231, a first magnetic element 2238 fixed to one end of the sliding rod 2233 for blocking the air discharging hole 2232, and an elastic element 2237 for driving the first magnetic element 2238 to block the air discharging hole 2232; wherein the exhaust holes 2232 are formed on the outer side of the exhaust channel 2231, the inner side of the exhaust channel 2231 is provided with a stop wall 2235, and the stop wall 2235 is provided with a through hole 2236; the sliding rod 2233 penetrates through the stop wall 2235, and the elastic member 2237 is a spring, which is sleeved on the sliding rod 2233, and has one end abutting against the stop wall 2235 and the other end abutting against the first magnetic element 2238. In this embodiment, the outer wall of the housing 50 forms a side wall of the connector 30, and the exhaust driving structure is embodied as the second magnetic element 34 located at the side wall of the connector 30. The tooth washing device 20 is placed on the connection seat, and due to the action of like charges repelling each other, the second magnetic element 34 drives the adjacent first magnetic element 2238 to move away from the air vent 2232 by overcoming the elastic force of the elastic element 2237, so that the interior of the second reservoir is communicated with the atmosphere. Of course, the same effect can be achieved by switching the positions of the air vent 2232 and the stopper wall 2235 to each other and setting the second magnetic element 34 to attract the first magnetic element 2238.

Example three:

Referring to fig. 6, unlike the first embodiment, the tooth washing apparatus 100 of the third embodiment does not include the ozone generator 60, but uses the first reservoir 10 to hold a prepared tooth washing solution, or filtered purified water, or any tooth washing solution with an inlet for sterilization. At this time, different from the first embodiment, when the tooth washing device 20 is placed on the connection seat, the pressure sensing module 71 sends a seat signal to the control module 72, and the control module 72 controls the liquid feeding device (the liquid pump 40 in the second embodiment) to start up, and fills water into the second liquid storage device 22 until the second liquid storage device is filled up, and then controls the liquid feeding device to close. At this time, the user can perform the washing function by removing the washing tool 20 from the connector 30 without opening the washing mode through the control panel 51.

As can be seen from the third embodiment, although the technical solution in the present application is mainly used to solve the problem of improving the convenience of the hand-held tooth cleaner in the case where the tooth cleaning solution needs to be prepared immediately before tooth cleaning, the technical solution does not hinder the use in the case where the tooth cleaning solution does not need to be prepared immediately before tooth cleaning. That is, the tooth cleaning device 100 of the present application has an important advantageous effect even though it is not necessary to prepare a tooth cleaning solution immediately before tooth cleaning. This is because the first reservoir 10 can contain a tooth washing solution which cannot be used for one time of tooth washing, and the tooth washing apparatus 100 can automatically fill the second reservoir 20, so that a user does not have to specially prepare the tooth washing solution before each time of tooth washing, and it is inconvenient to manually fill the second reservoir 20 with the tooth washing solution.

Example four:

the fourth embodiment is different from the third embodiment in that the air exhausting structure 223 is provided on the first reservoir 10, the liquid feeder, and the second reservoir 22, and the air exhausting driving structure is not provided in the fourth embodiment.

As shown in fig. 7, in the fourth embodiment, the first reservoir 10 includes a reservoir chamber 11 and a gas inlet chamber 12. In this embodiment, the liquid delivery device is a gas booster pump 43, and the inlet end of the gas booster pump is disposed in the inlet chamber 12, and the outlet end of the gas booster pump is disposed in the liquid storage chamber 11. The air-assisted pump 43 delivers the dental cleaning solution to the liquid supply nozzle 31 by pressurizing the air in the liquid storage chamber 11. In this embodiment, the liquid storage chamber 11 is communicated with the liquid supply nozzle 31 through the water passage 44, and the on-off valve 45 is disposed on the water passage 44 and used for controlling the opening and closing of the water passage 44. In this embodiment, the switch valve 45 and the gas booster pump 43 are both electrically connected to the control module 72.

referring to fig. 8, in the fourth embodiment, the exhaust structure 223 includes an exhaust channel 2231 having an exhaust hole 2232, a sliding rod 2233 slidably disposed in the exhaust channel 2231, a plug 2234 fixedly connected to one end of the sliding rod 2233 for plugging the exhaust hole 2232, and an elastic member 2237 for driving the plug 2234 to plug the exhaust hole 2232; wherein, the elastic part 2237 is a spring; in this embodiment, the exhaust hole 2232 is disposed at an end of the exhaust channel 2231 close to the inside, a stop wall 2235 is disposed at one side of the exhaust channel 2231 close to the outside, and a through hole 2236 is disposed on the stop wall 2235; the slide rod 2233 extends through the stop wall 2235; the elastic member 2237 is sleeved on the sliding rod 2233, and one end of the elastic member abuts against the stopping wall 2235, and the other end abuts against the plug 2234.

when the user puts the tooth washing device 20 on the connection seat, the pressure sensing module 71 sends a seat signal to the control module 72, and the control module 72 controls the liquid feeding device and the switch valve 44 to be opened, so as to fill the second liquid storage device 22 with the tooth washing liquid. At this time, the gas pressure in the second reservoir 22 gradually increases with the liquid injection until the stopper 2234 is away from the vent 2232 against the elastic force of the elastic member 2237, so that the inside of the second reservoir 22 is open to the atmosphere. After the second reservoir 22 is filled, the controller 72 controls the gas pressurizing pump 43 and the on-off valve 44 to be closed.

Thus, it will be appreciated that the liquid delivery device may be any device or mechanism known at the time of filing that is capable of delivering the dental rinse from the first reservoir 10 to the dental rinser 20. In addition, the liquid feeder is not necessarily integrated with the first reservoir 10, but may be part of the dental scaler 20, such as by evacuating the second reservoir 22 to deliver the dental cleaning liquid from the first reservoir 21 to the second reservoir 22 through the liquid feeding nozzle 31.

The description of the above specification and examples is intended to be illustrative of the scope of the present application and is not intended to be limiting. Modifications, equivalents and other improvements which may occur to those skilled in the art and which may be made to the embodiments or portions thereof through a logical analysis, inference or limited experimentation in light of the above teachings or the above teachings, and which may be incorporated in the practice of the invention or the related art, are intended to be within the scope of the invention.
