Referring to fig. 1 to 3, a check valve nozzle according to a first embodiment of the present utility model includes a base 10 and an elastic body 20. Wherein, the base body 10 is made of hard materials such as plastics, stones, timbers, metals and the like, a cavity 11 is arranged in the base body 10, and a first through hole 12 is arranged on the outer wall of the cavity 11. In this embodiment, the first through hole 12 is located on the outer end wall of the cavity 11 for communicating the inner and outer spaces of the cavity 11. In other embodiments of the present utility model, the first through hole 12 may be located at other positions of the outer wall of the cavity 11, such as a sidewall.

The base body 10 is further provided with a positioning block 13 protruding outwards on the outer end wall of the cavity 11, and the positioning block 13 is arranged corresponding to the first through hole 12. It will be appreciated that the locating block 13 is provided with a concave surface 131 which is in the shape of a closed arc, the concave surface 131 extending from the outer end wall of the cavity 11 towards the end of the locating block so that the locating block 13 is substantially in the shape of a cone. The concave surface 131 is provided with a second through hole 132, and the second through hole 132 is communicated with the first through hole 12.

The elastic body 20 is made of an elastic material such as natural rubber, elastic plastic, etc., and has an ability to recover after elastic deformation. The shape of the elastic body 20 is matched with that of the base body 10, the elastic body 20 is sleeved on the base body 10, and the inner cavity of the elastic body 20 is communicated with the cavity 11 through the second through hole 132 and the first through hole 12. It can be understood that the elastic body 20 is provided with an opening 21 at a position corresponding to the positioning block 13, the opening 21 is matched with the shape of the positioning block 13, and the opening 21 is in transition fit with the positioning block 13.

In the embodiment, the transition fit between the opening 21 and the positioning block 13 can close the opening 21 when the inner wall of the elastic body 20 is not stressed, so that the liquid in the cavity 11 cannot leak out; simultaneously, the opening 21 can be opened when the inner wall of the elastic body 20 is pressed, so that the liquid in the cavity 11 can be discharged through the first through hole 12, the second through hole 132 and the opening 21 in sequence, and further the non-return effect is achieved. In other embodiments of the present utility model, the degree of transition fit between the opening 21 and the positioning block 13 may be adjusted, so that the inner wall of the elastic body 20 opens the opening 21 when not under force, and the liquid in the cavity 11 may be discharged through the first through hole 12, the second through hole 132 and the opening 21 in sequence; at the same time, the inner wall of the elastic member 20 closes the opening 21 when being sucked, so that the liquid in the cavity 11 can not leak out.

Referring to fig. 4 to 7, a check valve nozzle according to another embodiment of the present utility model is different from the first embodiment in that in other embodiments, the positioning blocks 13 have different shapes, numbers and arrangement manners due to the concave surfaces 131 which are different from each other. In other embodiments of the present utility model, the positioning block 13 is made to have other shapes by providing the concave surfaces 131 in different shapes, numbers and arrangement modes.

For clarity, certain features of the utility model that are described in the context of separate embodiments may also be provided in combination in a single embodiment. Furthermore, the various features of the utility model which are described in the context of a single embodiment may also be used in combination in a subcombination, alone or in any suitable manner.
