Abstract

A switching device for a kitchen sprinkler has a central spindle (2). The water inlet of the central spindle is communicated with a third cavity formed between a floating supporting cover (6) and a water distributing body (5). The rotation motion of a roller (84) is transmitted to the floating supporting cover through a gear transmission mechanism to change the angle of the water distribution holes (62) set on the floating supporting cover, so as to adjust the water outflow of a sprinkler cover (4) or bubbler (3). This device has simple structure and is easy to be controlled.

Description

Kitchen shower switch

Technical field

The present invention relates to a switching device, and more particularly to a switching device for a kitchen shower.

Background technique

Existing kitchen showers generally have two water outlet modes, bubble water and shower water to suit different needs. CN201053519Y discloses a switching device for a kitchen shower button, which is implemented with a shower body, a mandrel, a button mechanism, a bubbler and a shower cover, wherein: the shower centrally forms two water inlet channels respectively a water inlet chamber connecting the bubbler and a water inlet chamber of the shower cover; the button mechanism is disposed on the side wall of the shower body, and includes two buttons having a reset function respectively aligned with the two water inlet channels; The spool assembly includes two valve bodies and a pressure plate, and further includes a return spring, the two valve bodies are respectively disposed in the two water inlet pipes of the mandrel, and the return spring is disposed below the valve body in the bubble water inlet pipe The middle portion of the pressure plate is pivotally connected to the upper part of the partition wall of the two water inlet pipes, and the two ends of the pressure plate are respectively pivotally connected to the upper portions of the two valve bodies. In the above-mentioned shower, when the shower is in the water-off state, the valve plug located in the bubble water inlet pipe is in the upper position under the action of the return spring, and is in the open state, and at the same time, due to the leverage effect, the shower water is at this time. The valve plug of the water pipe moves downwards and is closed. However, in the above-described shower valve spool assembly, the natural state is that the shower water inlet passage is closed, and the bubble water inlet passage is opened. Therefore, when the shower water is required to be showered, it is necessary to press and hold the corresponding water to the corresponding The button of the bubble water inlet passage allows the shower water inlet passage to move upward to be opened. Once the button is released, the pressure of the water flow is used to counteract the elastic force of the return spring in the bubble water inlet pipe, and therefore, in the loose When the button is opened, the above structure is not suitable for forming a shower water with a small flow rate (at this time, the water flow pressure is insufficient to offset the spring force of the return spring), and the purpose of long pressing the button to reach the shower water is inevitably inconvenient. .
