[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] A transmission pump body and a water flosser having the transmission pump body are provided in the preferred embodiment of the present invention; Figure 1-2As shown, it includes a housing 10, a pump body 30 disposed within the housing, and a transmission assembly 50 connected to the pump body, which compresses the air in the pump body to spray water. The water flosser also includes a water inlet assembly 20 connected to the pump body, which introduces water into the pump body, and a water spray assembly 60, which compresses the water in the pump body and discharges it through the water spray assembly to act on the teeth for flushing. The pump body is also connected to a drainage assembly 70 to discharge the remaining water in the pump body. The transmission assembly is controlled by a control panel to operate, and the housing is installed in a water storage container and sealed by the housing. The water inlet assembly is placed in a container (not shown in the figure) to achieve water inlet and flushing operations of the water flosser.

[0034] Specifically, such as Figure 1-2 As shown, the housing 10 includes a front bracket 100 and a rear bracket 101. The pump body 30 and the transmission assembly 50 are placed in the space enclosed by the front bracket and the rear bracket, and the front bracket and the rear bracket are fixed and locked by the top cover 102. The transmission assembly 50 includes a battery 500 and a motor 501. The battery and the motor are both electrically connected to the control board 40. The motor is driven by the control board to drive its speed, and the specific speed is determined by the working gear of the control board. The motor shaft is connected to a gear set 502, and the end of the gear set is connected to a piston 503. The rotation of the motor shaft drives the gear set to rotate to push the piston up and down. The piston is placed in the pump body 30. When the piston moves up and down, it compresses the air in the pump body, thereby achieving water intake through the water inlet assembly, water spraying through the water spray assembly 60, and drainage operation can also be performed through the drainage assembly 70. The nozzle assembly 60 includes a high-pressure nozzle 600 and a nozzle fixing seat 602 for fixing the high-pressure nozzle. The nozzle fixing seat is connected to the shell and connects the high-pressure nozzle to the shell. The nozzle assembly also includes a nozzle clip 601 for further fixing the high-pressure nozzle. The high-pressure nozzle is further fixed by the nozzle clip.

[0035] Furthermore, if Figure 5-9 As shown, the transmission assembly 50 includes a motor 501, a gear assembly connected to the motor shaft and driven to rotate synchronously by the rotation of the motor shaft. The gear assembly includes a motor gear 5020, which rotates synchronously with the motor shaft, and also includes a first gear 5021 and a second gear 5023. The first gear is fixed by a first optical axis 5022 and rotates under the action of the motor gear. The second gear is placed above the first gear and fixed by the second optical axis and rotates around the second optical axis. The second gear is provided with an eccentric wheel 5027 connected thereto. The eccentric wheel is placed at a non-center position of the second gear and can rotate around the second optical axis. The eccentric wheel is provided with a connecting rod 5024. The rotation of the eccentric wheel drives the connecting rod to move up and down, thereby driving the piston 503 to move up and down. The piston moves up and down in the pump body, thereby changing the pressure in the pump body to achieve water spraying, water intake and drainage operations.

[0036] Furthermore, if Figure 5-9 As shown, an eccentric wheel cavity is provided on one side of the connecting rod 5024, and the eccentric wheel is placed in the cavity, and the rotation of the eccentric wheel drives the connecting rod to move up and down. A travel groove 50242 is also provided on the connecting rod, and the second optical axis moves in the travel groove to limit the up and down movement of the connecting rod, thereby limiting the distance the piston moves up and down. It should be noted that the movement distance can also be determined based on the radius of the eccentric wheel rotating around the second optical axis. The pushing part 50241 above the connecting rod is connected to the piston 503 through the third optical axis 5026 and realizes synchronous movement. A pushing head 5031 is provided on the upper end of the piston, and a piston head 5030 is provided on the outer sleeve of the pushing head. The operation of the water flosser is realized by the movement of the piston head in the pump body. By setting up a double-layer gear transmission, the volume of the water flosser is reduced, the noise of the product during use is reduced, and the user's experience is improved.

[0037] Furthermore, if Figure 10-13 As shown, the pump body 30 is a four-way shape, with a water pumping cavity 304 provided inside. A water spray hole 301 is provided above the water pumping cavity, and a one-way duckbill valve 300 is provided at the water spray hole to prevent water entering the high-pressure nozzle from entering the pump body again. A piston sliding arm 305 is provided below, and the piston head moves in the piston sliding arm to push the liquid in the water pumping cavity into the high-pressure nozzle or the drainage component, or to suck water into the water pumping cavity through the water inlet component. The left side of the pump body is provided with a water inlet hole 302, which is connected to the water inlet assembly. The water inlet assembly includes a water inlet pipe joint 201, which is connected and fixed to the top cover via a fixing seat 205. A one-way valve plate 204 is provided in the water inlet pipe structure to prevent water from entering the water inlet pipe from the pumping cavity. The other side of the water inlet pipe joint is connected to the water inlet pipe 200, and the other end of the water inlet pipe is connected to a gravity ball 202. A water inlet 203 is provided on the gravity ball. The gravity ball ensures that the water inlet is always at a lower water level in the water storage container, which is convenient for use. At the same time, multiple sets of waterproof rings are provided on the water inlet pipe joint to prevent water in the water storage container from entering other spaces. Waterproof rings can also be provided at multiple locations on the water irrigator to increase the waterproofness of the water irrigator when in use and prevent water from entering other spaces. A drain hole 303 is provided on the right side of the pump body. The drain hole is connected to the drain assembly 70 to drain water, preventing residual moisture in the pump body from causing bacteria to grow in the pump body, making it safer and more hygienic.

[0038] Furthermore, if Figure 3-4 and Figure 14As shown, a high-pressure nozzle hole 1022 is formed above the top cover 102, and the high-pressure nozzle is connected to the top cover through the high-pressure nozzle hole, and a baffle 1021 and a limit seat 1023 are provided on the top cover. The high-pressure clip is provided with a clip 6011 corresponding to the high-pressure nozzle hole, and a spring 6010 is connected to the left side of the clip, and the other end of the spring is in contact with the baffle 1021. A nozzle fixing hole 6013 is provided in the middle of the clip, and the high-pressure nozzle hole is provided through the nozzle fixing hole. At the same time, a stopping arc surface 6012 is provided in the nozzle fixing hole, and the stopping arc surface abuts against the side wall of the high-pressure nozzle hole, through the elastic force of the spring. The fastener is in close contact with the top cover, thereby fixing the high-pressure nozzle. A limit plate 6014 is provided on the fastener corresponding to the limit seat 1023. The limit plate prevents the fastener from moving toward the side of the baffle. Therefore, when the high-pressure nozzle needs to be replaced, the spring needs to be pulled and then moved in the radial direction of the high-pressure nozzle to remove the fastener. Then the high-pressure nozzle can be replaced. The same method can be used for installation. After the spring is released, the spring generates a stopping force on the baffle, and the high-pressure nozzle can be further fixed by the fastener, which facilitates the replacement of the high-pressure nozzle and is more stable when in use. At the same time, a charging port 1020 is provided on the top cover, and the battery is charged through the charging port. A bump is provided at the lower end of the top cover, and the bump and the bracket are connected by a buckle to facilitate the installation and removal of the bump and the bracket. The locking cavity 1025 provided below the top cover can also fix the front bracket and the rear bracket.
