Description

Technical Field

[0001] The invention relates to a waterproof wall switch. Background Art

[0002] A wall switch refers to an electrical switch installed on the wall surface, which can generally be divided into touch-type and mechanical wall switches. The mechanical wall switch usually includes a shell, a panel, an electrical connection component and an operation button. The shell includes a accommodating cavity, and the electrical connection component is arranged in the accommodating cavity. The electrical connection component includes a contact group and a transmission member. The contact group includes a static contact and a moving contact for connecting the electrical appliance and the power supply respectively. The transmission member is arranged between the operation button and the contact group and constitutes a transmission coordination between the two. The rear end of the shell is embedded in the wall to fix the shell. The wiring harness for external connection of the electrical appliance and the power supply is connected to the contact group by passing through the shell. The panel is arranged on the surface of the wall through the front end of the shell. A mounting hole is provided on the panel. The operation button is swingably set on the panel through the mounting hole, and the panel is protruded near the swing center of the operation button. The electrical appliance is turned on and off by the operation button on the operation panel.

[0003] However, the wall switches in the prior art are often installed in bathrooms as bathroom heater switches. During use, there is a possibility that the user's hands may be wet when touching the operating buttons or being exposed to splashing water. There must be a gap between the switch panel and the operating buttons for the relative movement of the two. Liquid is likely to enter the accommodating cavity through these gaps, which may easily lead to accidents. For mechanical wall switches in this use environment, some coping methods have appeared on the market, such as providing an elastic silicone cover between the transmission part and the contact group of the wall switch to separate the contact group and the transmission part. This setting has the problem of high cost and certain difficulty in assembly; or installing a cover plate on the panel to cover it, and the cover plate is hinged or slid on the panel to block splashing water. Such a setting requires additional cost on the one hand, and is still relatively dangerous when the user's hands are wet. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides a waterproof wall switch which has good waterproof effect, simple structure and low cost.

[0005] To achieve the above-mentioned objectives, the present invention provides a waterproof wall switch, comprising a panel and a shell, wherein the panel is provided with a plurality of operating buttons and mounting holes for installing the operating buttons, the shell is provided with an electrical connection assembly and a transmission member constituting a linkage between the operating buttons and the electrical connection assembly, the panel is provided with a surrounding edge and a plurality of raised portions, the surrounding edge is arranged around the panel, the plurality of raised portions are arranged in sequence on the panel corresponding to the positions of the operating buttons, the plurality of mounting holes are respectively provided on the plurality of raised portions, and a channel is formed between the surrounding edge and the plurality of raised portions.

[0006] The advantages of adopting the above technical solution are: by arranging a surrounding edge on the panel and arranging a plurality of raised portions in sequence at the corresponding operation button positions, and arranging the mounting holes on the raised portions, a channel composed of the surrounding edge and the plurality of raised portions is formed on the panel. When liquid splashes onto the panel, since the raised portions are arranged corresponding to the operation buttons, the liquid will lose kinetic energy under the initial shielding of the operation buttons, and then will be guided into the channel only under the action of gravity or will flow toward the ground along the operation buttons and then be guided into the channel. Moreover, since the mounting holes are arranged on the raised portions, it is difficult for the liquid to enter the interior of the switch through the mounting holes on the raised portions without the action of external force, thereby avoiding the hidden dangers of liquid splashing or the contact switch buttons when the user's hands are wet. The waterproof effect is good, and only the structure of the panel needs to be changed, and only the injection mold of the panel needs to be adjusted. The structure is simple and the cost is low.

[0007] The present invention can be further configured as follows: the operation button is provided with a shielding portion extending toward the panel, the shielding portion is arranged around the raised portion, and the shielding portion includes ribs located at both ends of the length direction of the operation button, the ribs can fit into the channel as the operation button swings, and when the ribs swing away from the channel, the surrounding edge can shield the end of the ribs.

[0008] By further setting, the operation button is extended toward the panel and a shielding portion is arranged around the raised portion, and the ribs at both ends of the operation button can fit into the channel when the operation button is swung or when it is close to the panel, or can form a shield for the end thereof when it is away from the panel. The shielding portion can prevent liquid from sliding along the button toward the end face where the mounting hole is located to the end face where the mounting hole is set on the raised portion, thereby ensuring a waterproof effect. When the rib fits into the channel, it is convenient to guide the liquid into the channel. When the operation button is swung until the rib is away from the channel, the rib can shield the end of the rib, thereby preventing liquid from directly reaching the end face where the mounting hole is located through the gap between the two, thereby further enhancing the waterproof performance.

[0009] The present invention may be further configured such that an opening connecting the channel and the outside is provided at the edge of the surrounding edge close to the ground.

[0010] Through further configuration, the liquid can be discharged directly when it slides to the edge close to the ground, avoiding liquid accumulation.

[0011] The present invention can be further configured as follows: the shell includes a first connecting portion, the first connecting portion is used to form a connection with the panel, and a slot and a limit column are respectively provided on the end faces facing each other of the first connecting portion and the panel, and the slot and the limit column can be plugged in and matched with each other.

[0012] Through further configuration, slots and limiting columns are respectively provided on the end faces facing each other of the first connecting portion and the panel, and the slots and limiting columns can be plugged in and matched with each other, so as to facilitate the initial positioning of the two, and then further screwed and fixed for easy assembly.

[0013] The present invention can be further configured as follows: the shell includes a second connecting part, the second connecting part is used to be embedded in the wall, the second connecting part is smaller than the first connecting part, an elastic sheet is sleeved on the second connecting part, and the elastic sheet is attached to the end surface of the first connecting part facing the wall.

[0014] Through further configuration, when the second connecting part is embedded in the wall, the elastic sheet sleeved on the second connecting part and in contact with the first connecting part can be deformed to fill the gap between the shell and the wall due to being pressed against the wall, thereby preventing liquid from seeping from the wall and the shell into the shell.

[0015] The present invention can be further configured as follows: comprising a junction box, the junction box cover being arranged at the second connection portion, the junction box and the limiting column being respectively provided with a card joint and a through hole, the card joint being able to pass through the through hole and form a card joint fit with the panel.

[0016] By further setting up this matching junction box cover at the second connection part, it is avoided that the contact part between the electrical connection harness of the external device and power supply and the electrical connection component inside the switch is exposed, and there is no need to set up additional components to cover the output end of the shell. The card connector set on the junction box and the card connection with the panel through hole constitute the preliminary positioning between the switch components, which is convenient for the testing link of the wall switch.

[0017] The present invention can be further configured as follows: an accommodating cavity is formed between the first connecting part and the second connecting part, and an extension part is provided on the first connecting part for forming a socket-fitting fit with the second connecting part, and a hook and a socket are respectively provided on the extension part and the second connecting part, and the hook is gradually smaller toward the socket-fitting direction of the extension part and the second connecting part.
