[0021] In order to facilitate a better understanding of the purpose, structure, features and effects of this application, this application is further described in conjunction with the accompanying drawings and specific implementation methods.

[0022] It should be noted that when an element is considered to be “connected to” another element, it can be directly connected to the other element or there may be an intervening element at the same time.

[0023] In this application, descriptions such as “first”, “second”, etc. are only used for descriptive purposes and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

[0024] In the description of this application, the terms "front", "back", "left", "right", "up", "down", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on this application.

[0025] In one embodiment, Figures 1 to 3As shown, the portable fan includes a housing 1, a brake assembly, and a thermostat 2. The brake assembly is housed in the housing 1, and the thermostat 2 is embedded in the housing 1 and exposed to the outside. The housing 1 includes an air inlet chamber 13, a fixed chamber 14, an air duct 15, and a receiving chamber 16 arranged along the length. The housing 1 also includes an air inlet 11 connected to the air inlet chamber 13, and an air outlet 12 connected to the air duct 15. The thermostat 2 comes into contact with the human body, and the housing 1 is provided with a vent 17 corresponding to the thermostat 2. The brake assembly is housed in the fixed chamber 14. The wind generated by the brake assembly blows toward the air duct 15, with part of the wind blowing out from the air outlet 12, and part of the wind passing through the thermostat 2 and blowing out from the vent 17.

[0026] By installing the thermostat 2, the user can adjust the temperature by touching it, providing a better user experience. The air inlet chamber 13, the fixed chamber 14, the air duct 15, and the accommodating chamber 16 are arranged along the length, which helps to reduce the cross-sectional area and make it more compact and portable. The air generated by the brake assembly simultaneously blows towards the user and helps dissipate heat from the thermostat 2. A single brake assembly can perform both functions.

[0027] In one embodiment, Figures 1 to 3 As shown, the temperature regulating component 2 includes a mounting component 21, a heat conducting component 22, a temperature controlling component 23 and a heat dissipating component 24. The mounting component 21 is mounted on the exterior of the shell 1, and the heat conducting component 22 and the temperature controlling component 23 are mounted on the mounting component 21. The heat conducting component 22 is provided on one side of the temperature controlling component 23, and the heat conducting component 22 is exposed outwardly from the mounting component 21. The heat dissipating component 24 is provided on the other side of the temperature controlling component 23, and at least part of the heat dissipating component 24 is accommodated in the shell 1. It should be understood that the heat dissipating component 24 dissipates heat for the temperature controlling component 23, and the heat dissipating component 24 is a part or medium with heat dissipation properties, which is not limited here. The temperature control component 23 generates heat when working, and a large amount of heat is generated when the temperature control component 23 continues to work. Therefore, the heat dissipation component 24 is provided on the other side of the temperature control component 23. The heat dissipation component 24 is thermally connected to the temperature control component 23. The heat dissipation component 24 discharges the heat generated by the temperature control component 23, thereby finally enabling the temperature control component 23 to continue to maintain a normal working state and extending the service life of the temperature control component 23.

[0028] In one embodiment, Figures 1 to 3As shown, the housing 1 is provided with a heat dissipation channel 18. One end of the heat dissipation channel 18 is connected to the air duct 15, and the other end of the heat dissipation channel 18 is connected to the vent 17. The heat dissipation channel 18 is connected to the air duct 15, allowing some air to flow from the air duct 15 to the heat dissipation channel 18. The heat dissipation element 24 is provided in the heat dissipation channel 18. Air flows through the heat dissipation element 24, removes the heat generated by the heat dissipation element 24, and is blown out through the vent 17 without affecting the air discharge effect of the air outlet 12.

[0029] In one embodiment, Figures 1 to 3 As shown, the portable fan is a neck-hanging fan. The shell 1 includes a first shell 1A and a second shell 1B that are symmetrically connected, and the first shell 1A and the second shell 1B are arranged around the human neck. The first shell 1A and the second shell 1B both include a free end and a connecting end. The free ends of the first shell 1A and the second shell 1B are not provided with the air inlet 11, and the first shell 1A and the second shell 1B are provided with the air inlet 11 near the free ends. The free ends of the first shell 1A and the second shell 1B are used to set switches and charging interfaces, which are convenient for switch control and charging. The structural design is reasonable and easy to assemble. Of course, in other embodiments, the air inlet 11 may be provided at the free ends and / or near the free ends of the first shell 1A and the second shell 1B.

[0030] The fixed cavity 14 of the first and second shells 1A, 1B corresponds to the air inlet 11 and is equipped with a brake assembly. The brake assembly draws air from the air inlet 11, passes through the air inlet cavity 13 and the brake assembly, and then blows it into the air duct 15. The connecting ends of the first and second shells 1A, 1B are both equipped with a receiving cavity 16. The air inlet cavity 13 is located near the free ends of the first and second shells 1A, 1B, corresponding to the air inlet 11. The receiving cavity 16 is located at the connecting end of the first and second shells 1A, 1B, resulting in a rational structural distribution.

[0031] At least a portion of the heat dissipation channel 18 is arranged in parallel with the accommodating cavity 16 in the width direction. The position of the connection end of the first shell 1A and the second shell 1B is reasonably utilized to arrange the heat dissipation channel 18 and the accommodating cavity 16 in parallel, thereby increasing the counterweight of the portable fan corresponding to the back neck and avoiding the situation where the position of the connection end is too light and presses the back neck forward. The heat conducting member 22 is close to the human neck, and the vent 17 is facing away from the human neck. The heat conducting member 22 directly adjusts the human neck in contact with it, and the hot air discharged from the vent 17 after passing through the heat dissipation channel 18 is facing away from the human neck, which provides a good user experience. In addition, in this embodiment, an air outlet 12 is also provided corresponding to the heat dissipation channel 18, which can dissipate heat to the back neck area of the human body and enhance the air circulation inside the shell 1.

[0032] In one embodiment, Figure 4 and Figure 5 As shown, the portable fan is a neck-hanging fan. The shell 1 includes a first shell 1A and a second shell 1B that are symmetrically connected, and the first shell 1A and the second shell 1B are arranged around the human neck. The first shell 1A and the second shell 1B each include a free end and a connecting end, and the connecting end of the first shell 1A and the second shell 1B and the position near the connecting end are both provided with the air inlet 11. The connecting end portion of the first shell 1A and the second shell 1B is used to connect and fix the two, and the remaining portion is provided with the air inlet 11, and the air inlet 11 is also provided at a position near the connecting end, so that sufficient air intake can be guaranteed without affecting the connection between the first shell 1A and the second shell 1B. Of course, in other embodiments, the connecting end and / or the position near the connecting end of the first shell 1A and the second shell 1B may also be provided with the air inlet 11.

[0033] The fixed cavities 14 of the first and second housings 1A, 1B are each provided with a brake assembly corresponding to the air inlet 11. The brake assembly draws air from the air inlet 11, passes through the air inlet cavity 13 and the brake assembly, and then blows it toward the air duct 15. The free ends of the first and second housings 1A, 1B are each provided with a receiving cavity 16. The air inlet cavity 13 is provided at the connection between the first and second housings 1A, 1B, corresponding to the air inlet 11, and the receiving cavity 16 is provided at the free ends of the first and second housings 1A, 1B. This creates a rationally distributed structure.

[0034] In the length direction, the heat dissipation channel 18 is arranged between the air duct 15 and the accommodating cavity 16, which is more conducive to forming the shell 1 with a small cross-sectional area, making it more comfortable to wear. The wind passes through the air duct 15 and then blows towards the heat dissipation channel 18, which does not affect the wind force and wind effect that normally flows through the air duct 15 and the air outlet 12. In addition, the heat dissipation channel 18 is arranged downstream of the air duct 15, which is conducive to alleviating the wind blockage caused by excessive air volume and avoiding noise when the air volume is too large. The heat conducting member 22 is close to the human neck, and the vent 17 is facing away from the human neck. The heat conducting member 22 directly adjusts the human neck in contact with it, and the hot air discharged from the vent 17 after passing through the heat dissipation channel 18 is facing away from the human neck, which provides a good user experience.

[0035] In one embodiment, Figures 1 to 5 As shown, the mounting member 21 and the heat conducting member 22 extend along the length direction of the housing 1, so the contact area between the heat conducting member 22 and the human neck is larger, and the user experience is better. Figures 1 to 3 As shown, a flow channel 211 is formed between the mounting member 21 and the housing 1. The flow channel 211 is connected to the air duct 15, which helps to alleviate the air blockage caused by excessive air volume and avoid noise caused by excessive air volume. Of course, in other embodiments, the flow channel 211 connected to the air duct 15 may not be provided.

[0036] In one embodiment, Figures 1 to 5 As shown, the portable fan also includes a power supply 5 and a control board 6. The power supply 5 is located in the accommodating chamber 16. The brake assembly includes a motor 3 and a blower 4. The motor 3, the power supply 5, and the temperature control element 23 are all electrically connected to the control board 6. The motor 3 is a three-phase high-speed motor that provides high-speed and stable rotation, ensuring high air volume and pressure, and achieving good blowing effect.

[0037] Furthermore, the fan 4 is an axial flow or diagonal flow fan. Axial flow or diagonal flow fans are more compact than centrifugal fans, which is beneficial for reducing the volume of the fixed cavity 14, thereby making the entire housing 1 compact.

[0038] In one embodiment, Figures 1 to 5 As shown, the fixed cavity 14 has a circular cross-section, and the air duct 15 has a portion with a reduced cross-section as it moves away from the fixed cavity 14. The reduced cross-section portion increases the wind pressure generated by the brake assembly, allowing the wind to flow more smoothly toward the downstream end of the air duct 15, thereby preventing backflow.

[0039] The above detailed description is only an illustration of the preferred embodiment of the present application, and does not limit the patent scope of the present application. Therefore, all equivalent technical changes made by using the description and illustrations of this invention are included in the patent scope of this invention.
