Description

Technical Field

[0001] This utility model belongs to the field of hair dryers, and in particular relates to a portable negative ion hair dryer. Background Technology

[0002] Traditional hair dryers are mostly one-piece structures with a fixed size, making them inconvenient to store and carry when traveling or on business trips due to their large size. At the same time, some detachable hair dryers have poor connection stability and poor sealing, which can allow dust to enter and affect the internal circuitry. Therefore, there is a need for a portable negative ion hair dryer to solve the above problems. Utility Model Content

[0003] The purpose of this utility model embodiment is to provide a portable negative ion hair dryer to solve the problems mentioned in the background art.

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

[0005] A portable negative ion hair dryer includes a handheld part and a hair dryer. The handheld part includes a handheld tube with several positioning grooves at the top and several limiting grooves on the outer surface of the handheld tube. Each limiting groove is rotatably connected to a limiting ring, and the limiting rings are connected to the same threaded tube. A plug is connected to the top of the handheld tube.

[0006] The blower includes a blower tube, a connector is connected to the bottom of the blower tube, a threaded pipe is threaded to the outside of the connector, a plurality of positioning plates are provided inside the connector, a socket is connected to the bottom of the blower tube, the socket is located inside the connector, the plug is inserted into the socket, and the socket is connected to the heating element, motor and ion generator inside the blower tube through a wire.

[0007] In a further technical solution, the limiting groove is circular in shape, and the limiting ring is circular in shape.

[0008] In a further technical solution, several positioning plates are inserted into the positioning groove, and the positioning groove limits the handheld tube through the positioning plates.

[0009] A further technical solution is that the threaded tube has anti-slip textures on its outside, which increases the friction on the outside of the threaded tube, making it less likely for the palm to slip on the outside of the threaded tube during rotation.

[0010] In a further technical solution, a sealing ring is connected to the outside of the connector, and the sealing ring overlaps with the top end of the threaded pipe.

[0011] In a further technical solution, the handheld receiver is equipped with a control switch, a controller, and a power supply module. The power supply module is connected to the controller, the controller is connected to the control switch, and the control switch is connected to a plug via a cable.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model features a reverse-rotating threaded tube. The reversed threaded tube outside the connector drives the handpiece downward through a limiting ring and a limiting groove. The moving handpiece causes the plug to be slowly pulled out of the socket. When the threaded tube is completely detached from the connector, the plug is completely detached from the socket. At this point, the handpiece can be separated from the hair dryer, and the handpiece and hair dryer can be placed side by side. The disassembled hair dryer reduces its space occupation, so the hair dryer can be conveniently placed in a storage structure for carrying.

[0014] This utility model features mechanical positioning of the positioning plate and positioning groove, combined with the threaded fastening of the threaded tube and connector, providing double protection for the connection stability of the handheld part and the blower part. During use, it is not easy to loosen or lose power due to shaking or collision. The plug and socket are precisely aligned and plugged in, ensuring reliable electrical connection and stable output of heating, blowing, and negative ion generation functions.

[0015] This invention features a threaded connection for initial sealing, a sealing ring for secondary sealing, and a limiting ring and a limiting groove for coordinated sealing, creating multiple lines of defense to effectively prevent dust and moisture from entering the internal circuitry and connection points. This delays component aging, reduces the probability of failure, and improves the lifespan and reliability of the hair dryer. Even when used in bathrooms or humid environments, its performance is guaranteed.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Example 1

[0027] like Figures 1-6 As shown, this utility model embodiment provides a portable negative ion hair dryer, including a handheld part 1 and a blower part 2. The handheld part 1 includes a handheld tube 11. The top of the handheld tube 11 is provided with a plurality of positioning grooves 12. The outer surface of the handheld tube 11 is provided with a plurality of limiting grooves 13. Each of the plurality of limiting grooves 13 is rotatably connected to a limiting ring 14. The plurality of limiting rings 14 are connected to the same threaded tube 15. The top of the handheld tube 11 is connected to a plug 17.

[0028] The handheld receiver 11 is equipped with a control switch, a controller, and a power supply module. The power supply module is connected to the controller, the controller is connected to the control switch, and the control switch is connected to the plug 17 via a cable.

[0029] The power supply module uses a rechargeable lithium battery (such as an 18650 lithium battery pack) and has overcharge, over-discharge, and short-circuit protection circuits to power the entire hair dryer, ensuring battery life and electrical safety; it can also be powered directly by a power cord.

[0030] The controller uses a microcontroller (such as the STM32 series) as the control center to receive and process control switch signals and coordinate the operation of components such as heating tubes, motors, and ion generators.

[0031] The control switch uses a touch button or rotary switch, which connects to the controller and is used by the user to input commands such as power on / off, fan speed setting (e.g., low, medium, high), and negative ion function activation / deactivation. The control logic is as follows: when the user operates the control switch, the switch signal is transmitted to the controller. The controller, according to a preset program (different button / knob settings correspond to different output power and function combinations), sends control signals to the heating element, motor, and ion generator to adjust the working status. At the same time, the controller can monitor parameters such as the power supply module's power and the operating current of each component in real time. In case of abnormalities (e.g., overcurrent, low power), it automatically triggers protection, cutting off the power supply to the corresponding component or shutting down the entire unit.

[0032] The threaded tube 15 has anti-slip texture 16 on the outside, which increases the friction on the outside of the threaded tube 15. During the rotation of the threaded tube 15, the palm is less likely to slip on the outside of the threaded tube 15.

[0033] The blower 2 includes a blower tube 21, with a connector 22 connected to the bottom of the blower tube 21. A threaded tube 15 is threaded to the outside of the connector 22. Several positioning pieces 23 are provided inside the connector 22. The positioning pieces 23 are all inserted into the positioning groove 12. The positioning groove 12 limits the handheld blower 11 through the positioning pieces 23.

[0034] The bottom of the hair dryer 21 is connected to a socket 24, which is located inside the connector 22. The plug 17 is inserted into the socket 24. The socket 24 is connected to the heating element, motor and ion generator inside the hair dryer 21 through the wire 26.

[0035] In this embodiment, the handheld tube 11 is moved so that the plug 17 inside the handheld tube 11 corresponds to the position of the socket 24, and the moving handheld tube 11 drives several positioning pieces 23 to be inserted into the corresponding positioning slots 12.

[0036] When the moving handheld tube 11 drives the threaded tube 15 to contact the connector 22, the threaded tube 15 is rotated. The rotating threaded tube 15 drives several limiting rings 14 to rotate in the limiting groove 13. The rotating threaded tube 15 is threaded to the outside of the connector 22. The rotating threaded tube 15 and the connector 22 cooperate to pull the handheld tube 11 to slowly insert into the connector 22, so that the moving handheld tube 11 drives the plug 17 to insert into the corresponding socket 24. When the rotating threaded tube 15 contacts the sealing ring 25, the rotation of the threaded tube 15 stops. At this time, the plug 17 is fully inserted into the socket 24. At this time, the handheld part 1 can complete the electrical connection with the blower part 2. Then, the control switch can be turned on to use the hair dryer.

[0037] After the hair dryer is finished using it, reverse the threaded tube 15. The rotating threaded tube 15 slowly unscrews from the connector 22. During this process, the reversed threaded tube 15 outside the connector 22 drives the handpiece 1 downward through the limiting ring 14 and the limiting groove 13. The downward movement of the handpiece 1 drives the positioning piece 23 downward within the positioning groove 12. The moving handpiece 1 also drives the plug 17 to slowly pull out of the socket 24. When the threaded tube 15 is completely disengaged from the connector 22, the plug 17 is completely disengaged from the socket 24. At this point, the handpiece 1 can be separated from the hair dryer. Then, the handpiece 1 and the hair dryer 2 can be placed side by side. The disassembled hair dryer reduces its space occupation, so the hair dryer can be conveniently placed in the storage structure for carrying.

[0038] Example 2

[0039] The difference between this embodiment and embodiment 1 is that the shape of the limiting groove 13 is circular and the shape of the limiting ring 14 is circular.

[0040] The connector 22 is externally connected to a sealing ring 25, which overlaps with the top end of the threaded pipe 15.

[0041] In this embodiment, since the threaded tube 15 is threaded to the outside of the connector 22, the gap between the threaded tube 15 and the connector 22 can be initially sealed. Since the top end of the threaded tube 15 contacts the sealing ring 25, the sealing ring 25 can seal the gap between the threaded tube 15 and the connector 22. Since the circular limiting ring 14 rotates in the limiting groove 13, several limiting rings 14 and limiting grooves 13 cooperate with each other to seal the gap between the threaded tube 15 and the handheld tube 11, so that the handheld tube 11 and the connector 22 can be connected together with a high degree of sealing.

[0042] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
