[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0022] See Figure 1 to Figure 2 As shown, a new type of water pump suction cup includes a circular base 1 and a connecting cylindrical head 2, wherein a suction cup cavity 3 with an opening at the bottom is arranged in the circular base; in this embodiment, the circular base and the connecting cylindrical head are both silicone structures.

[0023] The top surface of the circular base is integrally formed with a truncated cone-shaped connecting portion 4 with a small top and a large bottom, and a cylindrical supporting portion 5 is integrally formed at the center of the top surface of the truncated cone-shaped connecting portion; a locking protrusion 6 is integrally formed at the top surface of the cylindrical supporting portion; and the connecting cylindrical head is integrally formed at the center of the top surface of the locking protrusion. In this embodiment, the diameter of the connecting cylindrical head is smaller than the diameter of the cylindrical supporting portion; the diameter of the locking protrusion is larger than the diameter of the cylindrical supporting portion. The cross-sectional edge of the locking protrusion is in a "<" shape. There are a truncated cone-shaped connecting portion, a cylindrical supporting portion and a locking protrusion between the connecting cylindrical head and the circular base. When in use, there is a good buffer space and it is not easy to cause the connection to break, which is conducive to improving the stability of use and service life.

[0024] In actual application, the bottom diameter of the truncated cone-shaped connection part is smaller than the top diameter of the circular base; an inclined guide surface 7 is provided at the connection between the bottom of the outer wall of the truncated cone-shaped connection part and the top surface of the circular base. The inclined guide surface improves the strength of the connection and reduces the risk of breakage.

[0025] Moreover, in actual application, the diameter of the cylindrical support portion is smaller than the top diameter of the truncated cone-shaped connecting portion; the top of the outer wall of the truncated cone-shaped connecting portion is provided with a chamfered transition surface 8. The chamfered transition surface can increase the effectiveness of the transition, and also increase the strength and toughness, which is conducive to improving the stability of use and service life.

[0026] The utility model has positive effects: the structure of the utility model is reasonably arranged, and it is provided with a truncated cone-shaped connecting part, a cylindrical supporting part and a locking protrusion part, which can not only ensure the overall strength of the whole, but also has good buffering performance, and is not easy to break at the connection, which is beneficial to improving the stability of use and service life, and is also beneficial to improving the water absorption, and has strong applicability and good practicality.

At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0028] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
