[0002] A hair dryer is a household appliance that is mainly used to dry hair or other wet items, as well as to shape hair styles. A hair dryer is usually composed of a set of electric heating wires and a small high-speed fan. It is driven by electricity to generate hot air to quickly dry the hair. A hair dryer is also commonly called a hair dryer, electric hot air blower, etc.

[0003] The hair dryer is a daily hairdressing product and one of the indispensable tools for haircutting. It can complete hairdressing and drying hair conveniently and quickly. However, due to the "7"-shaped structure of the traditional hair dryer, it occupies a large area and is extremely inconvenient to store, especially when traveling. It is not suitable to store it in a bag. However, in home use, placing it randomly will affect the appearance of the room. Therefore, there is an urgent need for a hair dryer with a foldable bracket that can be adjusted at multiple angles. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies of the prior art, such as large occupied area and extremely inconvenient storage, the utility model aims to provide a travel-friendly, portable and foldable hair dryer.

[0005] To achieve the above-mentioned purpose, the utility model provides a portable and foldable hair dryer for travel, comprising a first shell, a second shell rotatably arranged relative to the first shell, a blower for blowing air is arranged in the first shell or the second shell; a first magnet is arranged on the first shell, and a third magnet for cooperating with the first magnet is arranged on the second shell;

[0006] The hair dryer also includes a control unit, an induction element used in conjunction with a magnet and electrically connected to the control unit, the blower is electrically connected to the control unit, the induction element is arranged on the shell and is triggered by a magnet that is movably arranged relative to the induction element, and the control unit obtains the trigger signal of the magnet received by the induction element to control the start and stop of the blower.

[0007] Preferably, the sensing element is arranged on the first shell, and is used to control the operating state of the fan to be turned off via the control unit when the sensing element senses the third magnet. This can avoid unnecessary energy consumption when blowing is not needed, and help improve the energy efficiency of the hair dryer. At the same time, the user does not have to manually turn off the hair dryer, but can automatically trigger the sensing element to turn off the fan by folding / flipping the first shell to the corresponding position, making it more convenient and labor-saving for the user to use.

[0008] Preferably, a first connecting portion is provided on the first shell body, and a second connecting portion is provided on the second shell body, and the first connecting portion and the second connecting portion are rotatably arranged. By rotating the first connecting portion and the second connecting portion, the user can adjust the overall shape of the hair dryer to achieve different wind directions and blowing angles, which helps to meet the user's personalized blowing needs. At the same time, the rotatably arranged connecting portion helps to fold the hair dryer into a more compact shape, thereby making it easier to store the hair dryer. This is in line with the design concept of portability and storage, making the hair dryer suitable for carrying during travel.

[0009] Preferably, a second connecting portion is provided with a second magnet for use with the first magnet, and the second magnet is used to adsorb with the first magnet when the first shell is unfolded relative to the second shell. When the first shell is unfolded relative to the second shell, the mutual adsorption of the first magnet and the second magnet will cause the two shells to automatically lock / adsorb / fit at a specific position. Such a design makes the hair dryer more stable when unfolded and not easy to fold or collapse during use. At the same time, through the magnetic connection method, users can more easily unfold and close the hair dryer without excessive physical force, which helps to improve the user-friendliness of the product.

[0010] Preferably, an insulating tube is provided in the second shell, and a heating component for heating the air blown out of the second shell is provided in the insulating tube. The design of the insulating tube helps to prevent the surface of the second shell from being overheated, thereby improving the safety of the hair dryer. This thermal insulation effect helps to reduce the risk of users accidentally touching hot surfaces when using the hair dryer. At the same time, the heating component is in the insulating tube, which can avoid excessive heat loss to heat the air passing through the hair dryer.

[0011] Preferably, the first connecting part and the second connecting part surround a second chamber, the control unit is arranged in the second chamber, the first connecting part and / or the second connecting part are provided with a column located in the second chamber, the control unit includes a circuit board, and the circuit board is provided with a through hole for accommodating the column.

[0012] Preferably, the control unit is located in the middle of the rotation axis of the first connecting part and the second connecting part, and the air blown by the fan flows through the upper and lower ends of the control unit. Since the control unit is located in the middle of the rotation axis, the air blown by the fan can flow evenly through the upper and lower ends of the control unit, which helps to ensure that the airflow is evenly distributed over the entire control unit, reducing local temperature differences or pressure changes caused by uneven airflow. At the same time, the evenly distributed airflow can make the heat dissipation of the control unit more even, thereby improving the stability and controllability of the system.

[0013] Preferably, a seal is provided between the first connection part and the second connection part and / or between the second connection part and the first shell, and the seal is used to seal the gap between the connection part and the connection part / shell. The seal may be silicone, polytetrafluoroethylene, etc. The seal can effectively prevent foreign substances such as dust, moisture, and chemicals from entering the interior of the connection part / shell, thereby protecting the internal components / control unit from contamination, thereby extending the service life of the equipment, and can also effectively avoid weak wind caused by outward wind flow.

[0014] Preferably, the seal includes a sealing protrusion arranged on the second connecting part, and a sealing groove for accommodating the sealing protrusion is provided on the first shell / first connecting part, which can further increase the wind flow outflow path and reduce the wind flow outflow. At the same time, by providing the sealing protrusion on the second connecting part and the sealing groove on the first shell or the first connecting part, it can be ensured that the seal has precise positioning during assembly, which helps to prevent the seal from shifting or failing during use and ensure an effective sealing effect.

[0015] Preferably, an air inlet is provided on the first shell, and a filter element for filtering dust, impurities and other particulate matter is provided on the air inlet. The presence of the filter element can effectively prevent dust, impurities and particulate matter in the air from entering the device or system, which helps to improve the air quality in the hair dryer and prevent these particulate matter from affecting the normal operation of the control unit or other components. The setting of the air inlet and the filter element can prevent dust and other particulate matter from entering the interior of the hair dryer, thereby protecting the internal components from wear, corrosion or other damage, which helps to extend the service life of the hair dryer and improve its reliability.

[0016] The beneficial effects of the utility model are as follows: the hair dryer can be folded so as to be more easily stored and carried, making it an ideal choice for traveling, which helps to reduce the volume of luggage bags; at the same time, the start and stop of the hair dryer is controlled by a magnetic trigger, which can provide a more convenient use experience and avoid accidental start-up in the folded state.
