Description

Technical Field

[0001] This utility model relates to the field of kitchen equipment technology, specifically to a quick-release range hood control device that is easy to maintain. Background Technology

[0002] Whether for home or commercial use, range hoods are essential kitchen appliances. Existing range hood control switches commonly use either button or touch operation. However, regardless of whether it's a button or touch control switch, the internal circuit board and the cover or housing of the control switch are separate components. When multiple circuit boards are stacked, they need to be tightened with screws at each level and positioned using a complex internal structure. During maintenance and disassembly, the screws on the circuit boards need to be removed first, and then the circuit boards need to be taken out, which is cumbersome and inconvenient. Therefore, we propose a quick-release range hood control device that is easy to maintain. Utility Model Content

[0003] The purpose of this utility model is to provide a quick-release control device for a range hood that is easy to maintain, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A convenient and easy-to-maintain quick-release range hood control device includes a controller housing, a cover plate for encapsulating the bottom port of the controller housing, and a circuit board disposed inside the controller housing. Positioning platforms are provided on both sides of the inner cavity of the controller housing, and the positioning platforms are used for the upper limit positioning of the circuit board. The top surface of the cover plate is provided with a support column extending into the inner cavity of the controller housing, and the support column is used for the lower limit positioning of the circuit board. Connecting columns extending into the inner cavity of the controller housing are provided at both ends of the top surface of the cover plate. Positioning bushings are fitted at both ends of the circuit board, and the positioning bushings are sleeved with the connecting columns.

[0006] Furthermore, a screw that is threadedly connected to the controller housing is recessed and installed inside the connecting post. A guide groove is provided at one end of the connecting post that extends into the controller housing and surrounds the outside of the screw. The positioning bushing is elastically embedded in the guide groove inside the connecting post and is flexibly installed into the guide groove.

[0007] Furthermore, the positioning bushing has slots extending from the guide grooves on both sides, and the circuit board has positioning grooves corresponding to the connecting posts at both ends. The two sides of the positioning grooves are respectively engaged into the slots extending from the guide grooves on both sides of the positioning bushing.

[0008] Furthermore, the circuit board is equipped with switches, a display screen, and indicator lights, and the top surface of the controller housing has keyholes that correspond to the switches, display screen, and indicator lights mounted on the circuit board.

[0009] Furthermore, the top surface of the controller housing is provided with a protective sleeve covering the keyhole. The protective sleeve is used to seal the keyhole and protect the switch, display screen and indicator light inside the keyhole from dust.

[0010] Furthermore, the bottom surface of the circuit board is provided with wiring terminals, and the top surface of the cover plate is formed with a wiring platform. The top edge of the wiring platform abuts against the bottom surface of the circuit board, and the wiring platform cooperates with the circuit board and the controller housing to form a groove for accommodating the wiring terminals.

[0011] The beneficial effects of this utility model are as follows:

[0012] This invention uses a positioning platform on the inner wall of the controller housing and a support column on the top surface of the cover plate to set the upper and lower limits for the circuit board, respectively. After the cover plate encapsulates the controller housing, the positioning platform and support column position and clamp the circuit board. The circuit board is then connected to the positioning bushing via a connecting column, and both ends of the circuit board are clamped onto the connecting column, thus assembling the circuit board and the cover plate as a single unit. This avoids the need to use fasteners to fix the circuit board, making it easier to assemble and disassemble the circuit board. Attached Figure Description

The top surface of the cover plate 5 has connecting posts 6 at both ends that extend into the inner cavity of the controller housing 1. The two ends of the circuit board 13 are fitted with positioning bushings 15, which are sleeved with the connecting posts 6. Specifically, the positioning bushings 15 are made of one of rubber, silicone, or silicone rubber. The upper and lower limits of the circuit board 13 can be set by the positioning platform 4 on the inner wall of the controller housing 1 and the support post 9 on the top surface of the cover plate 5, respectively. After the cover plate 5 encapsulates the controller housing 1, the positioning platform 4 and the support post 9 position and clamp the circuit board 13, and the two ends of the circuit board 13 are sleeved with the positioning bushings 15 through the connecting posts 6, thereby clamping the circuit board 13 and the cover plate 5 together, avoiding the use of fasteners to fix the circuit board 13, and making it easier to disassemble and assemble the circuit board 13.
