Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, specifically a high-speed hair dryer that automatically starts and stops upon human handshake. Background Technology

[0002] High-speed hair dryers, as a common hair drying and styling tool, are popular among consumers due to their ability to quickly dry hair, strong airflow, and low noise. However, existing high-speed hair dryers have some safety hazards and inconveniences during use. For example, if a user temporarily puts down the hair dryer and forgets to turn it off, the hair dryer may continue to run. If there are obstructions in front of the hair dryer's outlet, the strong airflow and high temperature generated by the fan could ignite the obstruction, causing a fire and posing a significant safety hazard. Although existing technology attempts to solve this problem by using a timer to shut off the fan when the temperature gets too high, this method also shuts off at regular intervals during normal use, causing inconvenience to the user and failing to accurately control the hair dryer's on / off state based on the user's actual usage. Utility Model Content

[0003] The purpose of this invention is to provide a high-speed hair dryer that automatically starts and stops upon human body contact with a handshake, in order to solve the problem of uncontrollable automatic start and stop mentioned in the background art.

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

[0005] A high-speed hair dryer that automatically starts and stops upon human body contact and handshake, comprising a main body, wherein an electric heating wire for heating airflow is fixedly installed on the inner wall of the main body.

[0006] A handle assembly includes a handle, the outer wall of which is snapped onto a housing, and the side wall of the handle is provided with a metal conductor and a touch chip. The metal conductor is electrically connected to the touch chip and a circuit board. The metal conductor is arranged in a closed manner around the inner wall of the handle housing, and the metal conductor is adapted to the cross-section of the inner cavity of the handle.

[0007] In a preferred embodiment of this utility model, the front outer wall of the main body is magnetically and detachably fixedly connected to a nozzle, the output end of the nozzle is flat, and an end cap is installed on the rear outer wall of the main body.

[0008] In a preferred embodiment of this utility model, a fan is fixedly installed on the inner wall of the handle, an air duct is provided on the inner wall of the handle, an air inlet is provided on the bottom side wall of the handle, and a reinforcing rib sleeve is snapped onto the outer wall of the front end of the handle.

[0009] In a preferred embodiment of this utility model, a filter screen is installed on the outer wall of the air inlet, and a power cord is fixedly installed at the bottom of the handle, the power cord being electrically connected to the circuit board.

[0010] In a preferred embodiment of this utility model, a cold air button and a heating button are fixedly installed on the outer wall of the rear end of the handle, and both the cold air button and the heating button are circular.

[0011] In a preferred embodiment of this utility model, the cold air button and the heating button extend to the outside of the housing, and the surfaces of the cold air button and the heating button are respectively provided with concave and convex textures of different shapes.

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] Example 1: As Figures 1-6 ,include:

[0026] The main body 100 has an electric heating wire for heating the airflow fixedly installed on its inner wall.

[0027] The handle assembly includes a handle 200, with a housing snapped onto the outer wall of the handle 200. A metal conductor 240 and a touch chip are provided on the side wall of the handle 200. The metal conductor 240 is electrically connected to the touch chip and the circuit board. The metal conductor 240 is arranged in a closed manner around the inner wall of the handle housing. The metal conductor 240 is adapted to the cross-section of the inner cavity of the handle 200.

[0028] The specific usage scenario of this embodiment is as follows: When the user holds the handle 200, the human body comes into contact with the metal conductor 240 on the side wall of the handle 200. Since the metal conductor 240 is arranged in a closed manner around the inner wall of the handle shell and matches the cross-section of the inner cavity of the handle 200, the human body and the metal conductor 240 form a capacitor. After the touch chip detects the change in the capacitance value, it transmits the signal to the circuit board. After receiving the signal, the circuit board controls the heating wire electrically connected to the circuit board to work. Air flows through the interior of the main body 100 and is heated by the heated heating wire, thereby blowing out hot air to realize the function of heating and drying hair. When the user puts down the hair dryer and the hand leaves the metal conductor 240, the touch chip detects that the capacitance value has returned to the initial state and feeds the signal back to the circuit board. The circuit board controls the heating wire to stop working and stop heating.

[0029] Example 2: Figures 1-3 The front outer wall of the main body 100 is magnetically and detachably fixed to the nozzle 110. The output end of the nozzle 110 is flat. The rear outer wall of the main body 100 is fitted with an end cap 120. The inner wall of the handle 200 is fixedly fitted with a fan. The inner wall of the handle 200 is provided with a vertically penetrating air duct. The bottom side wall of the handle 200 is provided with an air inlet 250. The front outer wall of the handle 200 is snapped with a reinforcing rib sleeve 210. The outer wall of the air inlet 250 is fitted with a filter screen. The bottom end of the handle 200 is fixedly fitted with a power cord 260, which is electrically connected to the circuit board.

[0030] The specific usage scenario of this embodiment is as follows: When the power cord 260 is connected to the power supply, the current is transmitted to the circuit board to power the entire hair dryer system. When the user turns on the cold air button 220, the fan installed on the inner wall of the handle 200 starts to run. The fan generates suction, and external air enters from the air inlet 250 on the bottom side wall of the handle 200. The filter on the outer wall of the air inlet 250 filters out dust, hair and other impurities in the air to ensure that the air entering the air duct is clean. The air rises along the air duct that runs up and down the inner wall of the handle 200 and enters the body 100. When the heating button 230 is turned on, the air is heated by the heating wire and then blown out through the nozzle 110, which is magnetically and detachably fixed to the front outer wall. Since the output end of the nozzle 110 is flat, it can concentrate the airflow to achieve efficient drying and styling. The reinforcing rib sleeve 210, which is snapped onto the front outer wall of the handle 200, enhances the structural strength of the handle 200, making it more stable during use and less prone to damage, ensuring the stable operation of the hair dryer.

[0031] Example 3: Figures 1-3 A cold air button 220 and a heating button 230 are fixedly installed on the outer wall of the rear end of the handle 200. Both the cold air button 220 and the heating button 230 are circular and extend to the outside of the housing. The surfaces of the cold air button 220 and the heating button 230 are respectively provided with different shaped concave and convex textures. The cold air button 220 and the heating button 230 are electrically connected to the touch chip and the circuit board.

[0032] The specific usage scenario of this embodiment is as follows: When the hair dryer is in working condition, the user can adjust the blowing mode according to their own needs. If the user wants the cold air mode, press the cold air button 220, which extends from the outer wall of the rear end of the handle 200 to the outside of the outer shell. The cold air button 220 is electrically connected to the touch chip and the circuit board. Pressing the button generates an electrical signal, which is transmitted to the circuit board via the touch chip. After receiving the signal, the circuit board controls the heating wire to stop working. At this time, the fan continues to run, and the cold air is blown out. If the user needs hot air, press the heating button 230. Similarly, an electrical signal is generated and transmitted to the circuit board. The circuit board controls the heating wire to be powered on and heats the air sent into the main body 100 by the fan, thereby blowing out hot air. The surfaces of the cold air button 220 and the heating button 230 are respectively provided with different shaped concave and convex textures, so that the user can quickly and accurately distinguish and press the desired button by touch, even without visual observation, to switch the blowing mode.

[0033] The working principle of this utility model is as follows: When used by those skilled in the art, holding the handle 200, the metal conductor 240 on the side wall of the handle forms a capacitor with the human body. After the touch chip detects the change in capacitance, it transmits the signal to the circuit board. After the power cord 260 is connected to the power supply, the current powers the circuit board, and the fan starts to run. Suction is generated in the air duct inside the handle 200. External air enters through the air inlet 250. The filter screen of the air inlet 250 filters dust, hair, and other impurities. The clean air rises along the air duct to the main body 100. If the heating wire is in working condition, the air will be heated and then blown out through the flat nozzle 110 connected magnetically at the front end of the main body 100, achieving efficient hair drying and styling. The front-end reinforcing rib 210 enhances structural strength and ensures stable operation. During the operation of the hair dryer, the user can adjust the blowing mode as needed. Pressing the cold air button 220 connects it to the touch chip and circuit board, and the generated electrical signal is transmitted to the circuit board via the touch chip, causing only the fan to run and blow out cold air. Pressing the heating button 230 also transmits an electrical signal to the circuit board, energizing the heating wire to achieve hot air output. The different shaped concave and convex textures on the surfaces of the cold air button 220 and the heating button 230 facilitate blind operation and quick mode switching. When the user puts down the hair dryer, the metal conductor 240 detects the capacitance value and returns to its initial state. The circuit board controls the fan and heating wire to stop working, and the hair dryer automatically turns off.

[0034] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
