Description

Single-handle wall-in type body group and faucet

Technical Field

The utility model relates to a single-handle wall-in type body group and a faucet.

Background

The existing single-handle wall-in faucet has various types of body group structures, the handles of the handles are upward and downward, so that the conventional water outlet requirements of left heat and right cold can be met, namely, hot water is discharged when the handles rotate to the left, cold water is discharged when the handles rotate to the right, and different water inlet waterways are required to be designed, so that the water inlet positions of the body groups are different. Therefore, body groups with different structures appear on the market, thereby leading to diversification of the body groups and uneasiness in standardization. Moreover, the terminal waterway is not easy to assemble and is inconvenient to operate.

For example, the specification of the patent with the Chinese utility model patent application number 201720491323.4 and the name of a wall-in shower faucet discloses a valve cover, wherein a handle is used for driving a handle seat to rotate through an adapter, and the handle seat is axially adjustable and connected with a control valve. Therefore, the handle seat can be driven to axially move relative to the valve cover of the control valve by rotating the handle, and the panel connected with the handle seat is linked to axially displace, so that different requirements on the installation depth of the switch body can be met. It can also be seen from the drawings that the handle is arranged towards the direction, the control valve is directly connected with the switch body, if the handle is required to be arranged downwards, the switch body or the structure of the control valve is required to be changed, and the standardization cannot be realized, so that the universality is poor.

Therefore, there is an urgent need for an improved structural approach that improves product versatility and facilitates end user assembly.
