[0028] This utility model proposes a desktop water flosser main unit.

[0029] Please see Figures 1 to 3 In one embodiment of this utility model, the main unit of the benchtop water flosser includes a housing 1, on which an opening 11 is provided, located on the bottom wall or side wall of the housing 1; a water pump assembly 2, including a pump body 21, a water outlet connector 22, and a water outlet pipe 23, wherein the pump body 21 and the water outlet connector 22 are disposed inside the housing 1, the pump body 21 having a water inlet 211 and a first water outlet 212, and the water outlet connector 22 having a water inlet connection port 221 and a water outlet connection port 222, the water outlet connection port 222 facing the top of the housing 1. The water outlet connector 22 is located at one end or the bottom. It is connected to the first water outlet 212 through the water inlet 221 and to the water outlet pipe 23 through the water outlet 222. The water outlet 22 is spaced apart from the inner wall of the housing 1 to form an installation space 24. The water outlet pipe 23 passes through the opening 11. A portion of the water outlet pipe 23 is located in the installation space 24 and its arrangement direction is adjustable. Another portion of the water outlet pipe 23 is located outside the housing 1.

[0030] The technical solution of this utility model adopts a water outlet connector 22 to connect the first water outlet 212 of the pump body 21. The water outlet connector 222 is set towards the top or bottom of the housing 1 so that the water outlet direction and the water inlet direction of the pump body 21 are arranged at 0 degrees or 180 degrees. The water outlet connector 222 is spaced apart from the inner wall of the housing 1 to form an installation space 24. The water outlet pipe 23 is set in the installation space 24 and its arrangement direction is adjustable. By adjusting the arrangement direction of the water outlet pipe 23 in the installation space 24 and passing through the housing 1 to connect the nozzle assembly, the water pump assembly 2 can be adapted to water irrigators with different water outlet directions.

[0031] In this embodiment, the housing 1 may have a cavity for mounting components such as the water pump assembly 2, and the water pump assembly 2 may be disposed within the cavity of the housing 1. The housing 1 may have an opening 11 for the water outlet pipe 23 to pass through the housing 1. The opening 11 may be located on the bottom wall or side wall of the housing 1, thereby facilitating the formation of different water outlets on the housing 1, and further facilitating the water outlet pipe 23 to pass through the housing 1 from different outlet directions. The water pump assembly 2 refers to a device that can convert electrical energy or mechanical energy into fluid power. The water pump assembly 2 may include a driver (not shown), a pump body 21, a water outlet connector 22, and a water outlet pipe 23. The driver drives the pump body 21 to operate, thereby drawing water from the water tank through the water outlet connector 22 and the water outlet pipe 23 to the nozzle assembly. The pump body 21 may have an inlet 211 and a first outlet 212. The inlet 211 may be located in the upper half of the pump body 21, and the first outlet 212 may be located in the upper or lower half of the pump body 21. The outlet connector 22 may be connected to the first outlet 212 through the inlet connection 221, so that the outlet connector 22 is connected to the pump body 21. The outlet connector 22 may be connected to the outlet pipe 23 through the outlet connection 222, thereby fixing the outlet pipe 23 to the outlet connector 22, thereby fixing the water outlet direction of the pump body 21. The water outlet direction and the water inlet direction of the pump body 21 may be arranged at 0 degrees or 180 degrees, thereby facilitating the adaptation of the pump assembly 2 to water flossers with different water outlet directions.

[0032] In this embodiment, the water outlet port 222 of the water outlet connector 22 is spaced apart from the inner wall of the housing 1, thereby forming an installation space 24. The design of the installation space 24 facilitates the adjustment of the water outlet direction of the water outlet pipe 23. A portion of the water outlet pipe 23 can be located within the installation space 24. This portion of the water outlet pipe 23 can be bent and extended to the opening 11 to adjust its arrangement direction. The water outlet pipe 23 passes through the opening 11 so that the other portion of the water outlet pipe 23 is located outside the housing 1 and connects to the nozzle assembly, thereby enabling the water outlet pipe 23 to be adapted to the water irrigator with the water outlet located on the side wall of the housing 1.

[0033] In this embodiment, a portion of the water outlet pipe 23 may be located within the installation space 24. This portion of the water outlet pipe 23 may pass directly through the opening 11, allowing another portion of the water outlet pipe 23 to be located outside the housing 1. It extends through a bend to connect with the nozzle assembly, thus enabling the water outlet pipe 23 to be adapted to a water flosser with its outlet located on the bottom wall of the housing 1. This application arranges the water outlet and inlet directions of the pump body 21 at 0 degrees or 180 degrees, and adjusts the arrangement direction of the water outlet pipe 23 within the installation space 24 to allow the pump assembly 2 to adapt to water flossers with different water outlet directions.

[0034] like Figure 2 , Figure 3 and Figure 5As shown, in one embodiment, the desktop water flosser main unit further includes a buffer 3. The inner sidewall of the housing 1 is provided with a first mounting portion 12, and the outer peripheral side of the pump body 21 is provided with a first connecting portion 213. The first connecting portion 213 is connected and fixed to the first mounting portion 12 through the buffer 3. The buffer 3 is disposed between the first connecting portion 213 and the first mounting portion 12, so that the water outlet 222 of the water outlet connector 22 and the inner wall of the housing 1 form the mounting space 24.

[0035] In this embodiment, by employing a buffer 3 disposed between the first connecting portion 213 and the first mounting portion 12, the pump body 21 is connected and fixed to the first mounting portion 12 through the first connecting portion 213 and the buffer 3. The vibration generated by the pump body 21 can be offset by the elasticity of the buffer 3, thereby preventing the vibration generated by the pump body 21 from being transmitted to the housing 1. Furthermore, by using a water outlet connector 22 with its bottom end spaced apart from the bottom wall of the housing 1 to form an installation space 24, the water outlet end of the pump body 21 is suspended within the housing 1, facilitating adjustment of the arrangement direction of the water outlet pipe 23.

[0036] In this embodiment, the first mounting portion 12 can be formed by enclosing the first abutting portion 121 and the second abutting portion 122, which are respectively arranged at intervals along the height direction of the housing 1, so that the buffer 3 is abutted and fixed by the first abutting portion 121 and the second abutting portion 122, thereby improving the stability of the connection between the buffer 3 and the first mounting portion 12.

[0037] like Figures 2 to 4 As shown, in one embodiment, the pump assembly 2 further includes a water inlet connector 25.

[0040] In this embodiment, connector 26 can be used to connect inlet connector 25 and outlet connector 22. Water storage chamber 261 can be connected to inlet connector 25 through inlet port 211, so that water in water tank is transported to water storage chamber 261 through inlet connector 25. Water in water storage chamber 261 flows to water passage chamber 262 through outlet hole 2611, and then water is transported to outlet connector 22 through water passage chamber 262, thereby making more reasonable arrangement of water passage inside pump body 21.

[0041] In this embodiment, the pump body 21 further includes a piston rod and a driver, the driver driving the piston rod. The connector 26 may have a cavity for the piston rod to move, the cavity communicating with the water storage cavity 261 and the water passage cavity 262. The driver drives the piston rod to reciprocate to change the air pressure inside the cavity, the water storage cavity 261 and the water passage cavity 262, thereby causing water in the water tank to be drawn into the pump body 21.
