Embodiment two:
this embodiment is basically the same as the first embodiment, and differs in that:
as shown in fig. 2, the valve core housing 1 at the lower end of the installation channel 11 is provided with a seal installation groove for installing the seal element 4, and the seal element 4 is installed on the seal installation groove.
The sealing portion 31 has a tapered sealing surface 311, and the sealing portion 31 abuts against the seal 4 by the tapered sealing surface 311 under the action of water pressure.
In the first embodiment, a planar sealing structure is adopted between the valve core shell 1 and the valve rod 3, the contact area of the planar sealing structure is relatively large, and when impurities and the like exist on the contact surface, certain instability exists in the sealing performance.
In the embodiment, a conical surface sealing structure is adopted, compared with a planar sealing structure, the conical surface sealing structure has the advantages that the sealing area is relatively reduced, and the sealing performance is more reliable. And the greater the water pressure, the better the tightness of the conical surface sealing structure.
In addition, a water outlet passage which can communicate with the nozzle hole 21 is formed in the valve stem 3 and between the valve stem 3 and the valve core case 1. The water outlet passage comprises a rod passage 32 arranged in the valve rod 3, at least one liquid inlet hole 33 arranged in the middle of the valve rod 3 and a clearance passage 34 arranged between the valve rod 3 and the valve core shell 1. In this embodiment, the outer diameter of the valve stem 3 body (except for the sealing portion 31) is smaller than the inner diameter of the valve core case 1.
When a user reversely buckles the cup on the cup holder 7, under the action of gravity of the cup, the valve rod 3 moves downwards to automatically open the water outlet channel, high-pressure water sequentially enters the spray head 2 through the gap channel 34, the liquid inlet hole 33 and the rod channel 32, and the spray head 2 washes the inner wall of the cup through the spray hole 21.
Because the water inlet area of the water outlet channel formed by the conical sealing surface 311 is opened relatively quickly, when the valve rod 3 moves downwards for a small distance, the gap channel 34 can be completely opened, and the rapid and normal water outlet of the water outlet channel is realized.
Compared with the structure of the first embodiment, the water inlet area of the water outlet channel is required to depend on the area formed by the water inlet hole 33 and the downward moving distance of the valve rod 3, and when the valve rod 3 moves down to the position that the water inlet hole 33 is completely exposed, the normal water outlet of the water outlet channel can be ensured.
Compared with the first embodiment, the present embodiment has the advantages that the downward moving distance of the valve rod 3 when the water outlet channel is completely opened is short, and the water outlet efficiency of the water outlet channel is higher.
The above embodiments are only preferred embodiments of the present utility model, and are not intended to limit the scope of the present utility model in this way, therefore: all equivalent changes in structure, shape and principle of the utility model should be covered in the scope of protection of the utility model.
