[0002] The water pump of an oral irrigator is the core component inside the oral irrigator, driving the entire cleaning process. Through precise design and technology, the water pump converts ordinary water sources into high-pressure and high-speed water flows. These water flows are like miniature water guns, capable of reaching areas such as between teeth and the edges of gums that are difficult to reach, effectively removing food residues, dental plaque, and other oral contaminants.

[0003] The structures of the water outlet and water inlet of common water pumps of oral irrigators on the market are relatively complex. A complex structure means more components and a more delicate assembly process, which increases the difficulty and cost of the water pump during production. At the same time, it also places higher requirements on the precision of production equipment and the technical level of workers. Therefore, it is necessary to further improve the existing technology. Summary of the Invention

[0030] Embodiment 1: As Figures 1-9 shown, the improved water flosser pump includes a pump 1 with a bottom and a hollow interior, and further includes a separator 2 having a water outlet 21 and a water inlet 22, a water outlet valve 3 having a through hole 30, and a water inlet valve 5 having an umbrella portion 51 and a rod portion 52. A driving mechanism is assembled in the pump 1. The separator 2 is assembled in the pump 1. The umbrella portion 51 is connected to the rod portion 52. The water outlet valve 3 is assembled on the top surface of the separator 2 and the water outlet valve 3 is disposed corresponding to the water outlet 21. The water inlet valve 5 is assembled on the separator 2 through the cooperation of the rod portion 51 and the water inlet 22 and the umbrella portion 51 abuts against the bottom surface of the separator 2. Water enters the interior of the pump 1 from the water inlet 22 and then sprays out from the water outlet 21. A limiting portion for preventing the water inlet valve 5 from falling off in the water inlet 22 is further provided at one end of the rod portion 52 away from the connection with the umbrella portion 51. A diaphragm portion with a diaphragm surface is further assembled in the pump 1. The diaphragm portion is located below the separator 2. The outer edge of the diaphragm surface abuts against the inner wall of the pump 1. A liquid storage space 10 is formed between the diaphragm surface and the separator 2. One end of the diaphragm portion away from the liquid storage space 10 is connected to the driving assembly. The driving assembly drives the diaphragm portion to change the volume of the liquid storage space 10, and at the same time realizes the opening of the water inlet valve 5 and the closing of the water outlet valve 3, or drives the closing of the water inlet valve 5 and the opening of the water outlet valve 3. The structure of this application is relatively simple, which makes the assembly speed faster, and can reduce the complexity and cost in the production process, enabling the manufacturer to produce products more efficiently and possibly passing the cost savings on to consumers in the form of more favorable prices, reducing the error rate in the production process, and improving the reliability and durability of the product.

[0031] Among them, the separator 2 is detachably assembled in the pump. During long-term use, it is inevitable that there will be accumulated dirt in the liquid storage space. Detachably assembling the separator in the pump enables the separator to be disassembled for replacement or cleaning, keeping the interior of the pump clean and hygienic and avoiding the risk of oral infection for users.

[0032] Among them, a groove 23 corresponding to the water outlet valve is provided on the top surface of the spacer 2 around the water outlet 21, and the water outlet valve 3 is assembled in the groove 23. The groove is provided to enable the water outlet valve to be assembled on the spacer.

[0033] Among them, the water outlet valve 3 includes a seat portion 31 and a head portion 32. The head portion 32 is provided on the seat portion 31. The seat portion 31 is assembled in the groove 23. The head portion 32 has an inclined surface 321 and a water outlet surface 322. One end of the inclined surface 321 is connected to the water outlet surface 322. The inclined surface 321 is gradually inclined from the water outlet surface 322 towards the bottom of the head portion 32. The through hole 30 is provided on the water outlet surface. The water outlet valve 3 is a duckbill valve. This design enables it to automatically open and close according to the change of the internal pressure of the pipeline. When the oral irrigator works, the internal pressure increases, and the outlet of the water outlet valve will gradually expand and open, allowing the water flow to be discharged at a high speed. When the oral irrigator stops working or the internal pressure decreases, the water outlet valve will automatically close under the action of the elasticity of its own material, preventing water or other media from flowing back. Moreover, the water outlet valve with this structure makes the liquid flow out more smoothly.

[0034] Among them, the water inlet 22 has one group or multiple groups, and multiple groups of the water inlets 22 are arranged at intervals. Arranging multiple groups of water inlets enables water to flow into the water pump more quickly.

[0035] Among them, a sealing sheet 4 is further assembled on the top surface of the spacer 2. A sealing sheet hole 40 for the water outlet valve 3 and the water inlet valve 5 to pass through is provided on the sealing sheet 4. The sealing sheet is provided to prevent water from overflowing through the gaps between parts when water enters the water pump from the outside or when water flows out of the water pump.

[0036] Among them, the water outlet valve 3 and the water inlet valve 5 are made of soft materials such as rubber and silica gel. These soft materials have excellent sealing performance. These materials can closely fit when subjected to pressure, forming an effective sealing layer, thereby preventing water or other oral cleaning media from leaking during the use of the oral irrigator. This is crucial for maintaining the cleaning effect and user experience of the oral irrigator.

[0037] Embodiment 2: As Figures 1-9 shown, an oral irrigator includes a housing with a water storage space inside and an opening on the top, a nozzle, and the improved oral irrigator water pump described above. The water pump 1 is assembled in the housing. The water inlet 22 communicates with the inside of the housing. At least part of the nozzle passes through the opening and is connected to the water outlet valve 3. The structure of the present application is relatively simple, which makes the assembly speed faster, and can reduce the complexity and cost in the production process, enabling the manufacturer to produce products more efficiently and possibly passing the cost savings on to consumers in the form of more favorable prices, reducing the error rate in the production process, and improving the reliability and durability of the product.

[0038] As described above, it is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
