The depth of the first connecting post 513 inserted into the first mounting groove 4411 is less than the depth of the first mounting groove 4411, so that when the first elastic member 52 elastically resets, it can drive the first valve body 51 to move along the side away from the first mounting portion 44, thereby allowing the first valve body 51 to be movably mounted on the first mounting portion 44. To improve the stability of the connection between the second valve body 61 and the second mounting portion 23, a second connecting post 613 is inserted into the second mounting groove 2311. The depth of the second connecting post 613 inserted into the second mounting groove 2311 is less than the depth of the second mounting groove 2311, so that when the second elastic member 62 elastically resets, it can drive the second valve body 61 to move along the side away from the second mounting portion 23, thereby allowing the second valve body 61 to be movably mounted on the second mounting portion 23.

[0061] like Figure 4 As shown, there is a first gap 53 between the first one-way valve 5 and the inner wall of the water inlet channel 21. The first gap 53 is used to connect the water inlet end of the water inlet channel 21 and the first opening 211.

[0062] Alternatively, the second one-way valve 6 has a second gap 63 between it and the inner wall of the water outlet channel 22, and the second gap 63 is used to connect the second opening 221 and the water outlet end of the water outlet channel 22.

[0063] In the embodiment, the first one-way valve 5 has the first spacing 53 between the inner side wall of the water inlet channel 21, so that the first one-way valve 5 can adopt a smaller type of one-way valve without affecting the sealing of the water inlet channel 21, thereby reducing the production cost of the water pump. The first spacing 53 is used to connect the water inlet channel 21 and the first water outlet hole 42, and when the water inlet channel 21 is in an open state, water enters the water inlet channel 21 and flows into the adjusting cavity 31 through the first spacing 53 and the plurality of first water outlet holes 42. The second one-way valve 6 has the second spacing 63 between the inner side wall of the water outlet channel 22, so that the second one-way valve 6 can adopt a smaller type of one-way valve without affecting the sealing of the water outlet channel 22, thereby reducing the production cost of the water pump. The second spacing 63 is used to connect the second water outlet hole 43 and the water outlet end of the water outlet channel 22, and when the water outlet channel 22 is in an open state, water enters the water outlet channel 22 and is delivered towards the outside of the water pump through the second spacing 63.
