Description

Technical Field

[0001] This utility model relates to the field of switches, and in particular to a switch structure that allows for quick installation. Background Technology

[0002] Currently, push-button switches are commonly used in commercial stoves. However, due to the high levels of oil fumes in commercial stove environments, the conductive metal contacts of contact switches are prone to poor contact due to oil buildup. Therefore, some push-button switches utilize magnetic induction, such as the stove control switch disclosed in patent CN205594493U. However, traditional push-button switches require bolts, nuts, or screws for mounting on a panel. For example, patent CN202598614U discloses a waterproof controller for an energy-saving burner in commercial kitchen equipment. This controller includes a housing with a tactile ignition control switch mounting hole. The housing is designed with a "round top and round bottom" structure, with mounting holes at the four corners of the upper side. During use, the waterproof controller is installed on the energy-saving burner through these mounting holes, which is cumbersome and inefficient. Utility Model Content

[0014] Beneficial effects

[0015] Compared with the prior art, the advantages of the quick-installation switch structure of this utility model are:

[0016] 1. The switch base and the mounting base are detachably connected by a rotating snap-fit ​​structure, which can be quickly installed on the mounting panel without the need for bolts, screws or other structures, making operation convenient and quick.

[0017] 2. In the rotary snap-fit ​​structure, the first limiting protrusion of the transverse slide groove engages with the second limiting protrusion of the rotary snap-fit ​​protrusion. After engagement, a certain amount of force is required to remove the rotary snap-fit ​​protrusion from the transverse slide groove, thereby releasing the rotary snap-fit ​​and disassembling the switch base and the fixed seat, reducing the probability of accidental loosening between the switch base and the fixed seat.

[0018] 3. The button and the switch base slide together and a first elastic element is provided between them, which can cause the button to spring back after the button is pressed.

[0019] 4. The bosses on the switch base are used to support the first elastic element and limit the first elastic element by means of several bosses to prevent the first elastic element from shifting.

[0020] 5. When installing the button and switch base, ensure that both the guide tube and extension piece on the button extend into the through hole of the switch base. The extension piece has a certain degree of elastic bending ability, allowing the retaining piece at the end of the extension piece to also pass through the through hole of the switch base until the retaining piece enters the guide notch at the end of the insert block. At this point, the extension piece resets, and the button and switch base are properly installed. The fit between the retaining piece and the guide notch will prevent accidental disengagement, making installation convenient. To disassemble the button and switch base, press each retaining piece in the middle until it all enters the through hole of the switch base, allowing the button to be pulled out of the switch base.

[0021] 6. When the switch base and the fixed seat are installed on the mounting panel, the second elastic element is compressed between the mounting panel and the fixed seat. Due to the action of the second elastic element, the fixed seat tends to move away from the switch base, which increases the clamping force of the second spring and the switch base on the mounting panel. At the same time, it makes it difficult for the second limiting protrusion of the rotating snap-fit ​​protrusion to loosen from the first limiting protrusion of the transverse slide groove, further improving the connection stability.

The circuit board is inserted into its inner cavity through the bottom opening of the fixed base 1 and fixed. The magnet moves up and down with the button 2. When the magnet moves downwards and approaches the Hall element, the Hall element sends a signal to the control chip.

[0045] The mounting base 1 is provided with a second elastic element 4 for abutting against the mounting panel 6. In this embodiment, the second elastic element 4 is a spring. It is sleeved on the outside of the annular protrusion 11 of the mounting base 1, the lower end of the second elastic element 4 contacts the top surface of the mounting base 1, and the upper end of the second elastic element 4 contacts the lower surface of the mounting panel 6.
