Description

Technical Field

[0001] This utility model relates to the field of hot air comb technology, specifically a hot air comb switching structure. Background Technology

[0002] The switching assembly on a hot air comb is the core component for controlling the start and stop of the equipment and adjusting the airflow speed and temperature. Early hot air comb switches only had start / stop functions; with technological advancements, their functionality has gradually expanded to multi-mode control, including: 1. Fan speed adjustment: Switch between high and low fan speed levels and control the fan speed by rotating the switch or pressing the button; 2. Temperature control: Integrated warm / cold air switching function, with the heating element and fan linked to achieve switching between hot air and natural air; 3. Safety protection: Built-in temperature protector, overcurrent protection and other modules to prevent equipment overheating or circuit failure.

[0003] In the existing technology, the hot air comb switch assembly is installed in a pre-reserved mounting slot on the housing, which has the following shortcomings: First, the housing needs to be produced in two half-housings first, and then the two half-housings are joined together. With this structure, the housing cannot be integrally formed, which complicates the assembly process and increases production costs. Second, the bottom of the mounting slot is flush with the inner wall of the housing. When the hot air comb switch assembly is installed in the mounting slot, the heat dissipation effect is not ideal. Utility Model Content

[0004] The purpose of this invention is to provide a switch structure for a hot air comb that simplifies assembly and has a good cooling effect.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A hot air comb switch structure includes a cylindrical housing, a switch mounting base, a switch, a switch movable piece, and a manual adjustment button. The cylindrical housing has a mounting hole and a sliding groove near one end. The sliding groove is located on one side of the mounting hole. The switch is mounted on the switch mounting base, which is inserted into the mounting hole. The switch movable piece is mounted in the sliding groove and connected to a gear shift block on the switch. The manual adjustment button is connected to the switch movable piece.

[0006] Furthermore, the mounting hole has slots on both sides, and the switch mounting base has hooks on both sides. The hooks engage with the slots to fix the switch mounting base in the mounting hole.

[0007] Furthermore, the manual adjustment button is located at the rear of the switch movable piece.

[0008] Furthermore, the front of the movable switch piece is provided with a connection hole, and the gear shift block on the switch is inserted into the connection hole.

[0009] Furthermore, the upper surface of the switch movable piece is flush with the outer circumferential surface of the cylindrical housing at the slide groove.

[0010] Furthermore, the switch has four positions: 0, C, 1, and 2. Position 0 is the off state; position C is the cold air setting; position 1 is the low heat setting; and position 2 is the high heat setting.

[0011] Furthermore, the cylindrical shell is integrally formed by injection molding.

[0012] The beneficial effects of this utility model are as follows: The switch mounting base in this invention adopts a recessed snap-fit ​​method, which not only facilitates the assembly of the switch onto the cylindrical housing, but also enables the cylindrical housing to be integrally molded through injection molding. This changes the existing structure where the cylindrical housing is formed by joining two halves, thus simplifying the manufacturing and assembly of the cylindrical housing. The recessed switch position maintains the original unobstructed airflow within the cylindrical housing. During use, airflow or cool air will pass around the switch, which can help cool the switch during prolonged use.

[0013] The switch of this utility model is mounted on a switch mounting base. The switch mounting base achieves modular assembly through the assembly method of "one placement, one clamping, and one locking", which improves production efficiency. Attached Figure Description
