Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, specifically to a hair dryer switch assembly and a hair dryer. Background Technology

[0002] Hair dryers are primarily used for drying and styling hair. Most current hair dryers use toggle switches for adjusting settings, such as fan speed and power on / off. In related technologies, the toggle switch employs a disconnect-type mechanical limit switch, where the conductive plate of the mechanical limit switch is connected to the hair dryer's main control board via a wire. By toggling the mechanical limit switch to different settings, the hair dryer operates in different modes; for example, toggling to the power-off position disconnects the power, while toggling to different fan speed settings adjusts the dryer's motor to the corresponding speed. However, the mechanical limit switches used in current toggle switches are relatively large, hindering the miniaturization of the hair dryer's handle diameter.

[0003] In addition, existing hair dryers also need to have function buttons, such as temperature adjustment and negative ion function switch. The conventional hair dryer switch component design separates the function buttons and the speed switch into independent areas, so that the two do not affect each other. For example, the function buttons are placed above or below the speed switch movement area, so that the speed switch movement is not affected by the function buttons. However, this will result in both of them being too long. In the context of miniaturizing hair dryers, an overly long switch area design will affect the overall aesthetics and make operation inconvenient. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hair dryer switch assembly, a hair dryer handle, and a hair dryer.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A hair dryer switch assembly, comprising:

[0007] A switch bracket, detachably mounted on the body of the hair dryer, has a mounting area including a function switch area and a sliding area, the sliding area covering the function switch area;

[0008] A circuit board is fixedly mounted on the inner side of a switch bracket, on which a function switch and a toggle switch are integrated. The toggle switch has multiple positions, and the function switch and the toggle switch are arranged along the axis of the circuit board.

[0009] The buttons are located in the function switch area and are configured to correspond to the function switches on the circuit board.

[0010] The push button is slidably positioned in a sliding area, and when slidable, it can actuate a toggle switch to switch between multiple gear positions.

[0011] The push button has an avoidance structure on its movement path, so that the operation of the button does not interfere with the linear sliding action of the push button.

[0012] The installation area is a recessed groove-shaped structure. The function switch area is located within the groove-shaped structure, which divides the groove-shaped structure into a front end area and a rear end area. The rear end area and the front end area are connected by a guide area, which is located on either side of the function switch area. The front end area is provided with a toggle window that allows the push button and the toggle switch to work together.

[0013] The push button is provided with a clearance groove for avoiding the button.

[0014] The length difference between the clearance groove and the function switch area is adapted to the moving distance of the push button.

[0015] The push button has a slot on its lower side for engaging with the lever of the toggle switch.

[0016] The push button is equipped with a toggle mechanism on its upper side for sliding the push button.

[0017] The function switch area is provided with a press window that allows the buttons to be linked with the function switches.

[0018] The function switch is a tactile switch.

[0019] A hair dryer includes a hair dryer body and the aforementioned hair dryer switch assembly. The outer peripheral surface of the hair dryer body is provided with an installation space, and the hair dryer switch assembly is fixedly installed in the installation space.

[0020] The beneficial effects of this utility model are:

[0021] Space optimization: The overlapping layout of the dual buttons and the shared circuit board design reduce the internal space occupied by the hair dryer;

[0022] Operation isolation: The two buttons are physically isolated by structural design to avoid accidental touches and mechanical interference;

[0023] Functionality expandability: The orthogonal directional operation design (press direction is perpendicular to the sliding direction) is ergonomic and facilitates one-handed operation. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0034] like Figure 1 and Figure 2 As shown, a hair dryer is disclosed, which includes a hair dryer body 10, which includes an inner bracket and an outer shell. The outer shell covers the entire bracket, and the bracket has an installation space for installing a hair dryer switch assembly. The outer shell is adapted to cover the entire installation space, leaving only space for the toggle of the function switch and the push button, so that the function switch and the push button can be operated directly.

[0035] like Figure 3 and Figure 4As shown, a hair dryer switch assembly consists of a switch bracket. A circuit board is fixed at the bottom of the switch bracket, and the length of the circuit board is shorter than the design of the switch bracket. The circuit board has a button and a push button. The dual-button design allows the button to be used to control temperature and other functions, such as the negative ion function. The control can be achieved by pressing and holding the button, and by using different output signals from the long and short presses to switch functions. Alternatively, different temperature adjustment signals can be output to the main control board based on the number of presses. For example, after one press, the temperature is adjusted to cold air; after two presses, it is adjusted to medium temperature; after three presses, it is adjusted to high temperature; and after another press, it is adjusted to cold air, and so on.

[0036] The push button is used to turn the power on and off and switch the wind speed. It has multiple speed settings, and different speeds can be switched by moving it.

[0037] like Figure 6 As shown, the switch bracket 100 is detachably mounted on the blower body 10 and has an installation area. The installation area includes a function switch area 140 and a sliding area. The sliding area covers the function switch area 140, that is, the function switch area is located within the sliding area, so that the two overlap. The total length of the sliding area is the length of the entire switch assembly. The overlapping arrangement of the two buttons can reduce the space occupied inside, and at the same time, the length requirement of the circuit board is smaller, which can reduce the overall length of the circuit board and reduce costs.

[0038] Circuit board 400 is fixedly mounted inside switch bracket 100, and integrates function switch 410 and toggle switch 420. Toggle switch 420 has multiple positions, and function switch 410 and toggle switch 420 are arranged along the axis of circuit board 400. Figure 5 As shown by the dashed line, the pressing position of the function switch 410 and the lever of the toggle switch are on the same axis, thus making the button and push button arranged in a straight line, thereby realizing one-handed operation.

[0039] The toggle switch extends in a long strip shape, and multiple gear positions are spaced apart along the length of the toggle switch, so that the linear movement of the push button directly drives the lever of the toggle switch to move between different gear positions.

[0040] Button 300 is located in the function switch area 140 and corresponds to the function switch on the circuit board 400. When button 300 is pressed, it can trigger the function switch on the circuit board to achieve function switching. At the same time, it is located in the function switch area and does not interfere with the action of the push button.

[0041] The push button 200 is slidably disposed in the sliding area, and when it slides, it can drive the toggle switch to switch between multiple gear positions. The push button is used to realize the gear switching of the toggle switch.

[0042] The push button 200 has an avoidance structure on its movement path. This avoidance structure can use the design of the notch to make the push button avoid the area where the button is located, so that the operation of the button 300 does not interfere with the linear sliding operation of the push button 200.

[0043] like Figure 6 As shown, the mounting area is a recessed groove-shaped structure. The function switch area is located within the groove-shaped structure and is a boss with its upper surface flush with the surface of the switch bracket. The boss has a mounting groove with a pressing window for the button 300 to be linked with the function switch 410. The button is pressable within the mounting groove, and pressing the button triggers the function switch on the circuit board. The function switch area divides the groove-shaped structure into a front area 120 and a rear area 110. The rear area 110 and the front area 120 are connected by a guide area 130, which is located on either side of the function switch area 140. The front area 120 has a toggle window 121 for the push button 200 to be linked with the toggle switch 420.

[0044] When the push button is set in the sliding area, the push button 200 is provided with a clearance groove 220 for avoiding the button 300. The connecting parts on both sides of the clearance groove are placed in the guide area, so that the whole can avoid the button when moving.

[0045] The trigger direction (Z-axis direction) of button 300 is perpendicular to the movement direction of push button 200. When the user presses button 300 down, the push button remains stationary due to the avoidance design; when the user slides the push button along the axis of the switch bracket, the guide area allows the push button to move freely, and the button's action is not disturbed.

[0046] The length difference between the clearance groove 220 and the function switch area 140 is adapted to the moving distance of the push button 200. That is, the action of the push button will not be restricted by the function switch area, nor will it interfere with the function switch area. This makes the actions of the push button and the button completely independent, and the latter is completely within the area of ​​the former.

[0047] like Figure 7 As shown, the push button 200 has a slot 240 on its lower side for engaging with the lever of the toggle switch 420. The lever is placed in the slot and can be moved back and forth by the push button.

[0048] like Figure 8As shown, the push button 200 has an actuating member 210 on its upper side for sliding the push button 200. The actuating member is connected to the push button by a snap-fit. The tab makes the actuating member 210 slightly higher than the surface of the push button, so that the actuating member can be exposed through the outer shell for easy operation.

[0049] In this embodiment, the toggle is a circular button, and its bottom is connected to the push button by a snap-fit ​​to achieve an integrated structure. In some other embodiments, the toggle can also be integrally formed from the surface of the push button, that is, a protrusion is set on its surface, or multiple anti-slip textures perpendicular to the direction of push button movement are used for operation.

[0050] Meanwhile, the push button extends downward on both sides to form sliding wings 250. The guide area is provided with a sliding groove adapted to the sliding. When the push button is installed on the switch bracket, the sliding wings are placed in the sliding groove 131 to play a guiding role.

[0051] Furthermore, since the push button is fixed to the switch bracket by the housing, several reinforcing ribs 230 can be provided on the upper surface of the push button to reduce the friction between the upper surface of the push button and the housing, so that less force is required when it is operated.

[0052] The function switch 410 is a tactile switch, which is triggered by pressing.

[0053] The switch assembly proposed in this application is not only for hair dryers, but also for handheld mechanisms such as curling irons. It can be used in any situation where speed and function switching are required.

[0054] like Figure 1 and Figure 2 As shown, this utility model also discloses a hair dryer, which includes a hair dryer body 10 and the aforementioned hair dryer switch assembly 20. The outer peripheral surface of the hair dryer body 10 is provided with an installation space, and the hair dryer switch assembly 20 is fixedly installed in the installation space.

[0055] The embodiments should not be regarded as limitations on the present invention, but any improvements made based on the spirit of the present invention should be within the protection scope of the present invention.
