Description

Sealing connection structure between ball head and barrel of faucet water outlet device

Technical Field

The utility model relates to a tap field, especially a sealing connection structure between bulb and barrel of tap water outlet device.

Background

Chinese patent document discloses a technical scheme that patent application No. 202122828568.0, name are "a tap goes out water structure", and bulb pole one end of this scheme is equipped with first bulb, and first bulb cover is located in the end of intaking, and it is equipped with first sealing member and second sealing member to intake the end endotheca, and first sealing member and second sealing member cover respectively locate on the first bulb and the sphere laminating of first bulb to play sealed effect between first bulb and the end of intaking. However, the solution has some disadvantages in practical application:

firstly, first sealing member and second sealing member suit are in intaking the end back respectively, just are formed with the gap between the inner wall of second sealing member and the end of intaking, also are formed with the gap between the inner wall of first sealing member and the end of intaking, and the gap between first sealing member and the end of intaking is linked together along the inner wall of the end of intaking directly with the gap between second sealing member and the end of intaking. Therefore, in the using process, when water flows to a gap between the first sealing element and the water inlet end in a seepage manner, the water flows can directly flow into the gap between the second sealing element and the water inlet end along the inner wall of the water inlet end easily and seep out, and the sealing performance of the water outlet structure of the water faucet is very poor.

Secondly, because the first sealing member is a specific sealing member, and is not a common standard sealing ring on the market, the first sealing member is attached to the spherical surface of the first ball head in a large area, so that when the ball head rod is swung, the first ball head is easy to move together with the first sealing member, the first sealing member can rub against the inner wall of the water inlet end, the first sealing member is easy to wear, the sealing performance is affected, and the leakage condition is caused. Simultaneously, its sphere laminating with first bulb in large-area ground has increased area of contact, is rotating the in-process of first bulb like this, still appears the condition of jamming easily.

Thirdly, because the first sealing element is a special sealing element instead of a common standard sealing ring in the market, a set of special die needs to be designed for manufacturing, so that the product design and production cost of the whole faucet water outlet structure are increased, and the market competitiveness is lacked. And when the first sealing element is damaged, the first sealing element cannot be purchased and replaced on the market conveniently in time, and the replacement and maintenance are also very inconvenient.

Therefore, in view of the disadvantages and shortcomings of the above-mentioned faucet, it is necessary to improve the structure of the faucet to make it more convenient for people to use.
