Technical Field

[0001] This utility model relates to the field of electric flame stove technology, and in particular to a waterproof structure for an electric flame stove. Background Technology

[0002] Electric flame cooktops are a common cooking appliance in home kitchens, and their waterproof and safety performance are key considerations in their design. Waterproofing is an essential feature of electric flame cooktops because water or other liquids can splash onto them during use and seep into the cooktop. Since the rectifier circuit board provides high-voltage current to the anode of the arc generator, moisture can break down the insulation, damaging the circuit board and other components, and even causing safety accidents.

[0003] A search revealed that prior art CN220186906U discloses an electric flame stove and its waterproof structure. The structure is characterized by: a rectifier circuit board with a non-perforated area and a perforated area for drainage; the non-perforated area includes an electronic component area and several intermediate conductor boards, which are not connected to each other; a mounting post for fixing the rectifier circuit board and a support pad for supporting the intermediate conductor boards are provided at the bottom of the housing; a drain outlet is also provided at the bottom of the housing; a panel is positioned on top of the housing, and the panel and the housing form a box. This utility model's waterproof structure for the electric flame stove employs multiple design features, including a large perforated area, non-connected intermediate conductor boards, a drain outlet, and waterproof sealant, effectively preventing short circuits caused by moisture infiltration in the rectifier circuit board and electronic components.

[0004] However, the above-mentioned electric flame stove has the following problems when in use: In actual use, not only is the burner installed on the panel, but the switch is also installed. However, the existing technology does not waterproof the switch. During use, water can easily enter the interior from the switch installation part, and may even cause the switch shaft to rust, affecting its rotation. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof structure for an electric flame stove, which solves the problem that existing electric flame stoves do not have waterproof treatment for the switch, so water can easily enter the interior from the switch installation part during use, and even cause the switch shaft to rust and affect rotation.

[0006] To achieve the above objectives, this utility model provides a waterproof structure for an electric flame stove, including a panel and auxiliary devices; The auxiliary device includes a switch mounting housing, a switch body, a knob, a pull rod, and a locking assembly. The top of the switch mounting housing is provided with a limiting platform and a water-blocking surface, and is installed in a mating hole on the panel through the locking assembly. The limiting platform is sealed to the panel surface with sealant. The switch body is installed at the bottom of the switch mounting housing, and its rotating shaft is rotatably connected to the switch mounting housing. The top of the rotating shaft is a square post with a threaded hole. The knob is installed on the top of the square post through the pull rod. The locking assembly is located on the bottom side of the switch mounting housing and abuts against the panel.

[0007] The contact point between the rotating shaft and the through hole inside the switch mounting housing is provided with an O-ring seal.

[0011] This utility model discloses a waterproof structure for an electric flame stove. The switch body is installed at the bottom of the switch mounting shell for direct protection. Furthermore, the limiting platform and water-blocking surface structure prevent water from contacting the rotating shaft of the switch body, reducing shaft corrosion. Then, the contact surface between the limiting platform and the panel is sealed with sealant to directly form a water-blocking structure. Water is not easily allowed to enter the interior through the gap between the mounting holes of the switch mounting shell and the panel, further reducing water ingress into the internal cavity of the rectifier circuit board.

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention. Example 1:

[0019] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of the waterproof design of the electric flame stove. Figure 2 This is a schematic diagram of the rotating shaft. This utility model provides a waterproof structure for an electric flame stove: it includes a panel 101 and an auxiliary device. The auxiliary device includes a switch mounting shell 102, a switch body 103, a knob 104, a pull rod 105, and a locking assembly. The locking assembly includes an abutment threaded ring 111 and an anti-loosening threaded ring 112. This solution solves the problem that existing electric flame stoves do not waterproof the switch, allowing water to easily enter the interior through the switch mounting area during use, even causing corrosion of the switch shaft and affecting rotation. It is understood that the aforementioned solution can improve the waterproof performance of the switch installation.

[0020] In this embodiment, the panel 101 directly adopts the structure disclosed in the prior art CN220186906U to accommodate the burner head. At the same time, the structure of the prior art can also be adopted for components such as the rectifier circuit board.

[0021] The switch mounting housing 102 has a limiting platform 106 and a water-blocking surface 107 on its top, and is installed in the mating hole on the panel 101 through the locking assembly. The limiting platform 106 and the mating surface of the panel 101 are sealed with sealant. The switch body 103 is installed at the bottom of the switch mounting housing 102, and its rotating shaft 108 is rotatably connected to the switch mounting housing 102. The top of the rotating shaft 108 is a square post 109 with a threaded hole. The knob 104 is installed on the top of the square post 109 through the pull rod 105. The locking assembly is located on the bottom side of the switch mounting housing 102 and abuts against the panel 101. The switch mounting housing 102 has a mounting cavity at its bottom, facilitating bolt fixation of the switch body 103. It is made of heat-resistant material with a heat-insulating coating on its surface. The limiting platform 106 provides a sealing fit between the switch mounting housing 102 and the panel 101. The cable length between the switch body 103 and the circuit board is sufficient for easy disassembly of the switch mounting housing 102 and the panel 101. The water-blocking surface 107 prevents water from contacting the rotating shaft 108. A threaded hole is provided on the square post 109. The knob 104 has a square cavity communicating with the square post 109, and a stepped hole communicating with the square cavity. The stepped hole facilitates the installation of the T-shaped pull rod 105. The stepped external thread end of the pull rod 105 directly connects to the threaded hole on the square post 109 and can be rotated using an Allen wrench. The locking assembly facilitates quick installation or removal of the switch mounting housing 102. The bottom end face of the knob 104 has a mating gap with the panel 101, which facilitates the operation of the switch body 103.

[0022] Secondly, an O-ring seal 110 is provided at the contact point between the rotating shaft 108 and the through hole inside the switch mounting housing 102. Multiple O-ring seals 110 are made of O-ring rubber rings for further sealing.

[0023] Then, the abutting threaded ring 111 is threadedly connected to the switch mounting housing 102 and abuts against the panel 101; the anti-loosening threaded ring 112 is threadedly connected to the switch mounting housing 102 and abuts against the abutting threaded ring 111. The abutting threaded ring 111 and the anti-loosening threaded ring 112 are of the same size. The abutting threaded ring 111 is used to fix the switch mounting housing 102, and the anti-loosening threaded ring 112 is used to provide a certain anti-loosening structure for the abutting threaded ring 111.

[0024] Finally, both the abutting threaded ring 111 and the anti-loosening threaded ring 112 have through holes on their end faces away from the panel 101. These holes are not connected to the threaded cavity. The holes facilitate the insertion of corresponding matching rods, allowing for the disassembly and reassembly of the abutting threaded ring 111 and the anti-loosening threaded ring 112. The rods can be installed symmetrically, facilitating limited rotation after the crossbar abuts.

[0025] When using this invention to waterproof the switch of an electric flame stove, the switch body 103 is installed in the bottom cavity of the switch mounting shell 102, providing direct protection and improving safety. Furthermore, the limiting platform 106 and the water-blocking surface 107 structure prevent water from contacting the rotating shaft 108 of the switch body 103, reducing corrosion of the rotating shaft 108. Then, the contact surface between the limiting platform 106 and the panel 101 is sealed with sealant, directly forming a water-blocking structure. Water is not easily allowed to enter the interior through the gap between the mounting holes of the switch mounting shell 102 and the panel 101, further reducing water ingress into the internal cavity of the rectifier circuit board. This solves the problem that existing electric flame stoves do not have waterproof treatment for the switch, and water can easily enter the interior from the switch mounting part during use, even causing corrosion of the switch shaft and affecting rotation. Example 2:

[0026] like Figure 3 and Figure 4 As shown, where Figure 3 This is a schematic diagram of the overall structure of the waterproof design of the electric flame stove. Figure 4 This is a schematic diagram of the clamping rod. Based on the first embodiment, this utility model provides a waterproof structure for an electric flame stove. The waterproof structure of the electric flame stove also includes a matching device, which includes a clamping rod 201 and a rotating plate 202.

[0027] The locking rod 201 is slidably connected to the pull rod 105 and is located on the head of the pull rod 105; the rotating plate 202 is integrally formed with the locking rod 201 and is elliptical in shape. A rectangular groove smaller than the thickness of its head is provided in the inner hexagonal hole of the pull rod 105 to facilitate the sliding insertion of the head of the locking rod 201, and the rotating plate 202 facilitates the rotation of the locking rod 201.

[0028] In this embodiment, the internal hexagonal hole of the pull rod 105 is easily damaged after repeated disassembly, thus affecting the disassembly of the pull rod 105. However, the locking rod 201 and the rotating plate 202 provide another way to disassemble or install the pull rod 105, facilitating its disassembly or installation.

[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
