Problems solved by technology

[0005] In order to maintain the operating feel of the switch, at present, no sealing structure is set between the button and the fixing seat, and the drainage method is used to solve the leakage problem. One drainage structure is to set another drain port at the bottom of the fixing seat, but this The water will be drained into the cabinet under the pool. If the drain pipe is connected to the drain outlet, and then the drain pipe is connected to the drainage facility, although the water will not leak into the cabinet, this will greatly increase the structure of the switch and drainage facilities. Complexity, making switches and drains not versatile
[0006] Some also use the switch sliding shaft and the switch seat connected to the outside of the cable and the cable outer tube as a drainage channel, and the water is first discharged from the fixed seat into the switch seat and then flows to the cable outer tube to be discharged. The parts and drainage are in the same way, after a period of use, the channel will be blocked, resulting in no drainage and switch failure

Embodiment 1

[0026] Embodiment 1, with reference to Fig. 1-4.

[0027] Refer to attached picture. The switch in the kitchen and bathroom drainage facilities includes a fixed seat 1, a button 2, and a sliding shaft 3. The fixed seat 1 provides a space 100 for pressing the button and a hole 10 for the sliding shaft to pass through. The lower end of the hole 10 is threaded to connect the switch seat 6, which is also a pipe, and the sliding shaft 3 passes through the hole 10, and its main part is in the switch seat 6. The sliding shaft is provided with a cam surface 30 that cooperates with the spring hook 7. The spring hook 7 is fixed on the switch seat 6 by the coil spring 8, and through the cooperation of the cam surface and the spring hook, the sliding shaft has two stop positions of different heights. , which corresponds to the opening and closing of the switch.

[0028] The fixing seat 1 has a peripheral wall 11 and a bottom wall 12 around and at the bottom of the abdication space 100 ,...

Embodiment 2

[0039] Embodiment 2, with reference to Figure 5

[0040] In this embodiment, the opening of the hole 10a for the sliding shaft to pass is not higher than the bottom wall 12, the hole wall of the hole 10a has a thickened inner step 13a, and the space above the inner step 13a is provided with the Sealed structure. Others are the same as in Embodiment 1. In this embodiment, the same reference numerals as in FIGS. 1-4 represent the same meanings.

Abstract

The invention provides a switch in kitchen and bath drainage facilities. A fixing base of the switch is provided with a peripheral wall and a bottom wall around and at the bottom of an avoiding space for a button, so that downward water penetration of the avoiding space is avoided. A hole through which a sliding shaft passes is provided with a sealing structure used for sealing the gap between the sliding shaft and the hole wall of the hole and preventing water from leaking down via the gap. A sliding aiding element is arranged on the peripheral wall of the fixing base and the sliding aiding element and the peripheral wall of the button jointly achieve the effects of guide and sliding aiding. An intake and exhaust channel is formed in the button or between the button and the fixing base. The technical solution combining semi-sealing and central sealing solves the problem of water leakage and guarantees operation hand feel.

Description

technical field [0001] The invention relates to a switch in kitchen and bathroom drainage facilities. Background technique [0002] For kitchen and bathroom facilities, there is a switch that is turned on by pressing a button, and turned off by pressing it again. This switch has a better operating feel and is a relatively high-end switch in kitchen and bathroom facilities. [0003] In actual use, the problem of water leakage in the gap between the switch button and the fixing seat is difficult to deal with when this switch is applied to drainage facilities. [0004] If this gap is sealed, the operating feel of the switch will be greatly reduced. For example, a sealing ring is added between the button and the surrounding wall of the fixed seat. Although this will greatly improve the problem of water leakage in the fixed seat, it will greatly increase the movement resistance of the switch and reduce the operating feel of the switch. [0005] In order to maintain the operati...
