Description

Technical Field

[0001] The utility model relates to the field of switches, in particular to a waterproof structure of a remote control switch. Background Art

[0002] A remote control switch is a device that controls the switch of an electrical appliance through a wireless signal. The working principle of a remote control switch is usually based on wireless technologies such as infrared, radio frequency, and Bluetooth. A user can send a signal through a remote control. After the signal is received by a receiver, the corresponding switch action is triggered. The remote control switch is commonly used to control various household appliances, such as lights, air conditioners, and garbage disposals. The remote control switch of the prior art usually includes a panel, a base, and a signal component. The signal component is arranged in the base. The panel is swingably arranged on the base and covers the signal component in the base. The signal component is prompted to send a signal by pressing the panel to swing it. However, due to the different requirements that the remote control switch needs to face, it is often necessary to optimize according to specific application scenarios. For example, a remote control switch for a garbage disposal is often installed in a kitchen, and there is a lot of oil smoke and water vapor in the kitchen itself, and it is also easier to contact with wet objects and be operated by the user with wet hands. Therefore, better protection is required to prevent external impurities from entering the switch and then contacting the circuit board of the signal component, resulting in the occurrence of switch failure.

[0005] The advantages of adopting the above technical solution are: a pressure plate and a dust cover are set in the base, so that the dust cover and the pressure plate are covered on the signal component in turn, and in addition to the protective effect formed by the panel and the base, two additional layers of protection are added through the dust cover and the pressure plate, which effectively prevents moisture from directly contacting the signal component, and achieves better waterproof and dustproof effects, which is more suitable for humid environments. The elastic material composition of the dust cover is emphasized, and the material characteristics are utilized to provide a certain degree of sealing, reducing the possibility of moisture penetrating through the gaps. The first rib and the second rib surrounding the signal component are set on the base, and the dust cover composed of the elastic material is sleeved on the first rib, which facilitates installation and makes the combination of the two tighter, thereby increasing the sealing of the structure. The edge of the outer pressure plate abuts against the second rib and is bolted to ensure stability.

[0006] The utility model can be further configured as follows: the base includes a matching edge and a raised portion, one end of the panel is swingably connected to the end of the base away from the raised portion, the matching edge and the raised portion constitute a circumferential surrounding of the base, the raised portion is arranged at the upper end of the base, and the panel can be reset to its other end flush with the raised portion after being swung, and the panel includes a corresponding matching edge extending to form an abutting edge, and the abutting edge can form an abutting fit with the matching edge after the panel is swung.

[0007] Through further configuration, a matching edge and a raised portion are provided on the base, so that one end of the panel is swung and connected to the end of the base away from the raised portion, and the other end of the panel close to the raised portion is swung up and down, and the panel will be flush with the raised portion after the swing is reset. First, a continuous matching edge and raised portion are used to form a continuous sealing ring, which helps to prevent moisture from penetrating from the edge of the base. On this basis, the other end can be reset to be flush with the raised portion. This design allows the panel to maintain good contact with the base when opened and closed, reduces gaps, and can also enhance waterproof performance and strengthen

[0008] The utility model can be further configured as follows: the signal component includes a circuit board, the base includes a first mounting position for mounting the circuit board, the first mounting position is recessed, and a plurality of bosses are arranged at the first mounting position, and the circuit board abuts against the bosses.

[0009] Through further configuration, a first mounting position for installing the circuit board is provided in the base, the first mounting position is recessed, and a plurality of bosses are provided at the first mounting position so that the bosses are in contact with the circuit board, and support is provided for the circuit board through the bosses, so that the circuit board can be higher than the bottom surface of the first mounting position. Even if liquid breaks through the protection and enters the inside of the dust cover, such a design can still prevent the liquid from contacting the circuit board, thereby further enhancing the protection effect.

[0010] The utility model can be further configured as follows: the panel includes a pressure head, the signal component includes an action arm that causes itself to work by swinging, the action arm includes a contact portion arranged corresponding to the position of the pressure head, and the pressure plate is provided with a connecting hole, and the connecting hole allows the pressure head to pass through when the panel swings.

[0011] Through further configuration, a pressure head that can correspond to the contact part of the action arm is set on the panel, and the pressure head can drive the action arm to swing when the panel swings. On this basis, a connecting hole is opened on the pressure plate, and the pressure head is passed through the connecting hole, and then the dust cover therein is driven to elastically deform to apply pressure to the contact part of the action arm. The connecting hole is opened on the pressure plate, which can better guarantee the overall waterproof performance.

[0012] The utility model can be further configured as follows: the signal component includes a light guide embedded in the panel and a lamp portion arranged on the circuit board, the dust cover and the pressure plate are respectively provided with a matching portion and a through groove, the matching portion and the through groove are both arranged between the light guide and the circuit board, and the matching portion is formed by being recessed and thinned by the dust cover.

[0013] Through further configuration, a lamp part is set on the circuit board, and LED lamp is mainly used. The status information is fed back through the lamp part. For this purpose, a matching part and a through groove are respectively provided at the positions where the dust cover and the pressure plate are aligned with the lamp part. Through the setting of the matching part and the through groove, the corresponding position can be thinned and focused, and the end of the light guide located in the direction of the base is extended to the through groove to ensure that the light guide can transmit the status of the lamp part on the circuit board, so as to better feed back information to the user, and the use of the matching part and the through groove can also achieve a better protection effect.
