[0030] Figure 1 is a perspective structural schematic diagram of a pump body structure according to an embodiment of the present application, as shown in Figure 1As shown, as one of the embodiments, the pump body structure comprises a three-way pump 10, a skin bowl 20 and a driving mechanism 30. The three-way pump 10 is provided with a water inlet 11, a water outlet 12 and a pump water outlet 13. One end of the skin bowl 20 is in communication with the pump water outlet 13, and the other end is connected to the output end of the driving mechanism 30. The side wall of the skin bowl 20 is in a crumpled shape.

[0031] It can be understood that when the skin bowl 20 is in a crumpled shape, it can provide better elastic recovery after being compressed, which helps the skin bowl 20 quickly recover to the original shape, so that the cleaning water flow can be pumped out at a constant frequency, improving the user experience.

[0032] The water outlet 12 of the three-way pump 10 and the pump water outlet 13 are located on the same vertical line, and the water inlet 11 is in communication with the body from the side of the three-way pump 10. The open end of the skin bowl 20 is fixed at the pump water outlet 13, and the other end opposite to the opening is connected to the output end of the driving mechanism 30.

[0033] Further, when the driving mechanism 30 is working, the driving mechanism 30 is used to drive the skin bowl 20 with a crumpled side wall to move back and forth to change the volume of the skin bowl 20. Further, when the skin bowl 20 is stretched, the cleaning water flow flows into the three-way pump 10 through the water inlet 11, and then flows into the inside of the skin bowl 20 from the pump water outlet 13. When the skin bowl 20 is compressed, the cleaning water flow stored in the skin bowl 20 is sequentially discharged through the pump water outlet 13 and the water outlet 12.

[0034] In this way, compared with the prior art, the skin bowl 20 with a crumpled side wall has low stretching and contracting resistance during actual work, which can improve the efficiency of pumping water flow, reduce the power required by the driving mechanism 30, effectively increase the endurance level of the oral irrigator, and improve the user experience.

[0035] Please refer to Figure 1 , Figure 2 and Figure 3 As one of the embodiments, the skin bowl 20 comprises a fixed section 21, a deformation section 22 and a matching section 23 which are sequentially communicated. The fixed section 21 is detachably arranged on the pump water outlet 13, and is used to fixedly cooperate with the pump water outlet 13 to play a sealing role between the three-way pump 10. The matching section 23 is connected to the output end of the driving mechanism 30, and is used to provide an area for the driving mechanism 30 to be stretched or compressed. The deformation section 22 is used to deform under the driving of the driving mechanism 30, so as to change the volume of the skin bowl 20, so that the skin bowl 20 can suck water flow from the water inlet 11 and discharge water flow to the pump water outlet 13.

[0036] As one of the embodiments, the side wall of the skin bowl 20 is provided with the following forms of folds: ① the side wall of the deformation section 22 is provided with folds, and the joint between the deformation section 22 and the fixed section 21 is provided with folds; ② the side wall of the deformation section 22 is provided with folds; and ③ the joint between the deformation section 22 and the fixed section 21 is provided with folds. The folds refer to the folds and overlapping parts generated by folding. One fold can be formed by two acute-angled triangles connected in opposite directions, or can be formed by only one acute-angled triangle.

[0037] As one of the embodiments, the number of folds formed by the side wall of the skin bowl 20 is less than or equal to three. It can be understood that appropriate folds can reduce the stretching resistance generated by the skin bowl during operation, so as to improve the efficiency of the skin bowl 20 in pumping the cleaning water flow. However, too many folds can reduce the surface precision, cause the entire structure to fail, and thus the skin bowl 20 loses the ability to pump the cleaning water flow outward. Therefore, in the embodiment, the number of folds formed by the side wall of the skin bowl 20 is less than or equal to three, that is, one, two or three.

[0038] As one of the embodiments, the interval end of the water outlet 13 is recessed along the axial direction to form a clamping groove 131, the end of the fixed section 21 is extended along the axial direction to form a clamping part 211, and the skin bowl 20 is detachably sleeved on the clamping groove 131 of the three-way pump 10 through the clamping part 211. In this way, the stability of the connection between the skin bowl 20 and the three-way pump 10 is improved, the skin bowl 20 and the three-way pump 10 are prevented from being separated during long-term use, the sealing of the liquid between the skin bowl 20 and the three-way pump 10 is improved, and the water leakage phenomenon is avoided.

[0039] As one of the embodiments, the end surface of the skin bowl 20 close to the driving mechanism 30 is outwardly extended to form a matching section 23. Figure 1 As shown in the structure, the output end of the driving mechanism 30 is a connecting rod, the end of the connecting rod is in a cylindrical structure and is inwardly recessed to form a positioning groove, and the matching section 23 is a protruding structure outwardly extended from the end surface of the skin bowl 20 close to the driving mechanism 30. In actual implementation, the matching section 23 is inserted and fixed in the positioning groove, so as to achieve the connection between the skin bowl 20 and the output end of the driving mechanism 30.

[0040] Please refer to Figure 4 As one of the embodiments, the driving mechanism 30 includes a fastener 31, and the matching section 23 is provided with a first fixing hole 231. In the structure shown in the figure, the skin bowl 20 reciprocates along the vertical direction under the driving of the driving mechanism 30, and the first fixing hole 231 penetrates along the direction perpendicular to the moving direction of the skin bowl 20, that is, penetrates from the horizontal direction.

[0041] Furthermore, a second fixing hole (not shown in the figure) is provided on the side wall of the output end of the drive mechanism 30. When the mating section 23 is inserted into the output end of the drive mechanism 30, the first fixing hole 231 and the second fixing hole (not shown in the figure) are correspondingly set. In this embodiment, the fastener 31 is a fixing pin used to pass through the first fixing hole 231 and the second fixing hole (not shown in the figure) to fix the mating section 23 to the output end of the drive mechanism 30. In this way, the tightness between the cup 20 and the drive mechanism 30 can be improved, and the phenomenon of the cup 20 and the output end of the drive mechanism 30 falling off during long-term use can be avoided.

[0042] In one embodiment, the inner wall of the leather cup 20 relative to the mating section 23 is aligned with the outflow direction of the water flow (e.g., Figure 4 As shown in AA), the compression section 24 is formed by extending the compression section. Specifically, in this embodiment, a mating section 23 protrudes downward at the center of the bottom end of the outer wall of the cup 20, and a compression section 24 protrudes upward at the center of the bottom end of the inner wall of the cup 20 opposite to the mating section 23. By providing the compression section 24, it is possible to ensure that the force transmission of the cup 20 is uniform and sufficient each time it is compressed or stretched. Furthermore, in conjunction with the pleats, the volume of the cleaning water jet sprayed outward each time can always be kept at a similar level, which can improve the user experience.

[0043] Please refer to Figure 1 or Figure 4 This application also provides a water flosser, including a water outlet, a nozzle, a water pump, and the pump body structure described above. One end of the water outlet is connected to the outlet 12 of the three-way pump 10, and the other end is connected to the nozzle. The output end of the water pump is connected to the inlet 11. Thus, when the water flosser is working, the water pump pumps clean water from the inlet 11 to the three-way pump 10, allowing the clean water to enter the cup 20 through the pump inlet 13. The drive mechanism 30 drives the cup 20, whose sidewalls are pleated, to reciprocate, so that the clean water can flow quickly and sequentially through the pump inlet 13, the outlet 12, and the water outlet, and finally be ejected from the outlet 12 at the front end of the nozzle. Through the above technical solution, the pleated cup 20 has low expansion and contraction resistance during actual operation, which improves the efficiency of pumping water flow and reduces the power required by the drive mechanism 30, effectively increasing the water flosser's battery life and improving the user experience.

[0044] As one implementation, the oral irrigator also includes a housing for protecting the various components. In the direction of water flow (e.g., ...) Figure 1 or Figure 4The housing is internally provided with a water outlet cavity, a containing cavity, a piston cavity and a driving cavity in sequence in the opposite direction, i.e. in the vertical direction. The water outlet element, the three-way pump 10, the skin cup 20 and the driving mechanism 30 are arranged in the water outlet cavity, the containing cavity, the piston cavity and the driving cavity respectively.

[0045] The above merely provides a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any change or replacement within the technical range disclosed by the present application can be easily thought by any person skilled in the art, and should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
