[0025] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0027] like Figure 1-Figure 3 As shown, a constant flow water pump comprises a water pump body 1, on which a water outlet pipe 11 and a water inlet pipe 12 of a certain length are arranged, the water outlet pipe 11 is arranged at the top of the water pump body 1, the water inlet pipe 12 is arranged at the side wall of the water pump body 1, a water outlet hole 101 is opened at the end of the water outlet pipe 11, a water inlet hole 201 is opened at the end of the water inlet pipe 12, the water outlet pipe 11 and the water inlet pipe 12 are arranged in parallel, the water outlet hole 101 and the water inlet hole 201 are arranged oppositely, the aperture of the water outlet hole 101 is larger than the aperture of the water inlet hole 201, the aperture of the water outlet hole 101 is set to 2.5MM, and the aperture of the water inlet hole 201 is set to 2.2MM;

[0028] In this way, when the aperture of the water outlet hole 101 is larger than the aperture of the water inlet hole 201, and the aperture design reaches a certain ratio, a very suitable water outlet pressure effect can be achieved, and it is more comfortable for human nasal or oral washing.

[0029] In some embodiments, Figure 1 , Figure 2As shown, the water outlet pipe 11 includes a limit platform 102 arranged at the bottom of the water outlet pipe 11, and the diameter of the limit platform 102 is set to 7.85-7.95MM, the water inlet pipe 12 includes a limit platform 202 arranged at the end of the water inlet pipe 12, and the diameter of the limit platform 202 is set to 7.05-7.15MM, and a sealing platform 103 is arranged above the limit platform 102, and the diameter of the sealing platform 103 is set to 5.15-5.2MM, and a sealing platform 203 is arranged below the limit platform 202, and the diameter of the sealing platform 203 is set to 4.35-4.45MM, the outer diameter between the water outlet hole 101 on the water outlet pipe 11 and the sealing platform 103 is set to 5-5.1MM, and the outer diameter between the water inlet hole 201 on the water inlet pipe 12 and the sealing platform 203 is set to 4.09-4.19MM;

[0030] In this way, as attached Figure 3 As shown, in the present embodiment, the sealing platform 103 is a raised annular structure, one end of the sealing platform 103 extends to contact with the limiting platform 102, and the other end of the sealing platform 103 extends in the direction of the water outlet hole 101. When the water pump body 1 is fixed inside the tooth washer or the nasal washer, it is only necessary to align the water outlet pipe 11 with the connecting pipe on the water outlet end and insert it until the front end of the connecting pipe on the water outlet end contacts with the limiting platform 102 to complete the water pipe docking installation at the water outlet end, and the assembly is very convenient. Since the aperture of the connecting pipe at the water outlet end is the same as the outer diameter at the water outlet hole 101, when the water outlet pipe 11 is fully inserted into the connecting pipe at the water outlet end, an extrusion state is formed between the water outlet pipe 11 and the inner wall of the connecting pipe at the water outlet end, further increasing the sealing effect, and the connection between the two is more stable, and the reasonable diameter size between each connection has reached the standard water pump accessories, thereby adapting to more models or shapes of tooth washer and nasal washer, etc.;

[0031] As attached Figure 1-3 As shown, when the water pump body 1 needs to be assembled, it is only necessary to align the water inlet pipe 102 on the water pump body 1 with the pipe on the water tank of the oral irrigator or nasal washer, and fully insert the water inlet pipe 102 into the pipe on the water tank. When the limit platform 202 on the water inlet pipe 102 contacts the top of the pipe on the water tank, the water inlet pipe 102 and the water tank are docked and fixed. Since the pipe aperture on the water tank is the same as the outer diameter of the water inlet pipe 102, when the water inlet pipe 102 is fully inserted into the water tank pipe, an extrusion state is formed between the water inlet pipe 102 and the inner wall of the water tank pipe, which further increases the sealing effect, and the connection between the two is more stable, and the reasonable diameter size between the connections has reached the standard water pump accessories, thereby adapting to more models or shapes of oral irrigators and nasal washers, etc.

[0032] Furthermore, the water inlet pipe 12 is a 7-shaped structure, and the length of the water inlet pipe 12 is set to 39-40.01MM. The outer diameter of the water inlet pipe 12 near the water inlet hole 201 is smaller than the outer diameter of the water inlet pipe 12 near the end, which further increases the firmness of the water inlet pipe 12 and prevents the water inlet pipe 12 from being damaged when being plugged in. The bottom of the water inlet pipe 12 is flush with the top surface of the water pump body 1.

[0033] Finally, it should be noted that the water pump body 1 includes a pump body and a drive motor. The drive motor 10 is arranged below the pump body. The connection structure between the drive motor and the pump body belongs to the prior art and will not be described in detail here.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
