The heat dissipation member 24 is arranged on the other side of the temperature adjusting member 23, and at least part of the heat dissipation member 24 is accommodated in the housing 1. It should be understood that the heat dissipation member 24 performs heat dissipation work on the temperature adjusting member 23, and the heat dissipation member 24 is a part or medium with heat dissipation properties, which is not limited herein. The temperature adjusting member 23 generates heat during work, and a large amount of heat is generated when the temperature adjusting member 23 continuously works. Therefore, the heat dissipation member 24 is arranged on the other side of the temperature adjusting member 23, the heat dissipation member 24 is in thermal conduction connection with the temperature adjusting member 23, the heat dissipation member 24 discharges the heat generated by the temperature adjusting member 23, and finally the temperature adjusting member 23 can continuously maintain a normal working state, and the service life of the temperature adjusting member 23 is prolonged.

[0028] In one embodiment, as shown in 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 in communication with the air duct 15, and the other end of the heat dissipation channel 18 is in communication with the air vent 17.

The heat dissipation member 24 is arranged in the heat dissipation channel 18, and the air flows through the heat dissipation member 24, taking away the heat generated by the heat dissipation member 24, and blowing out from the air vent 17, without affecting the air outlet effect of the air outlet 12.

[0029] In one embodiment, as Figures 1 to 3 As shown, the portable fan is a neck fan. The housing 1 includes a first housing 1A and a second housing 1B arranged symmetrically and connected, and the first housing 1A and the second housing 1B surround the neck of the human body. The first housing 1A and the second housing 1B each include a free end and a connecting end, and the free end of the first housing 1A and the second housing 1B is not provided with the air inlet 11, and the first housing 1A and the second housing 1B are provided with the air inlet 11 near the free end. The free end of the first housing 1A and the second housing 1B is used to set a switch and a charging interface, which is convenient for switch control and charging, and the structure design is reasonable and convenient for assembly. Of course, in other embodiments, the free end of the first housing 1A and the second housing 1B and / or the position close to the free end can be provided with the air inlet 11.

[0030] The first housing 1A and the second housing 1B are provided with the brake assembly corresponding to the air inlet 11, and the brake assembly sucks air from the air inlet 11 and blows it to the air duct 15 via the air inlet cavity 13 and the brake assembly. The connecting end of the first housing 1A and the second housing 1B is provided with a containing cavity 16, the air inlet cavity 13 is arranged at the position close to the free end of the first housing 1A and the second housing 1B, and the containing cavity 16 is arranged at the connecting end of the first housing 1A and the second housing 1B, so that the structure is reasonably distributed.

[0031] At least part of the heat dissipation channel 18 is arranged in parallel with the accommodating cavity 16 in the width direction, and 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, increase the counterweight of the portable fan corresponding to the back of the neck, and avoid the situation that the position of the connection end is too light to press the back of the neck forward. The temperature guide 22 abuts against the neck of the human body, and the air vent 17 faces away from the neck of the human body. The temperature guide 22 directly adjusts the neck of the human body in contact therewith, and the hot air discharged from the air vent 17 via the heat dissipation channel 18 faces away from the neck of the human body, and the user has a good experience. In this embodiment, corresponding to the heat dissipation channel 18, an air outlet 12 is also provided, which can dissipate heat to the back of the neck of the human body and strengthen the air circulation in the shell 1.

[0032] In one embodiment, as shown in Figure 4 and Figure 5 The portable fan is a neck hanging fan. The shell 1 includes the first shell 1A and the second shell 1B arranged in symmetry and connected, and the first shell 1A and the second shell 1B surround the neck of the human body. The first shell 1A and the second shell 1B each include a free end and a connection end, and the connection end and the position close to the connection end of the first shell 1A and the second shell 1B are each provided with the air inlet 11. Part of the connection end of the first shell 1A and the second shell 1B is used for connection and fixation of the two, and the rest is provided with the air inlet 11, and the air inlet 11 is also provided at the position close to the connection end, so that sufficient air inlet amount can be ensured without affecting the connection of the first shell 1A and the second shell 1B. Of course, in other embodiments, the connection end and / or the position close to the connection end of the first shell 1A and the second shell 1B can each be provided with the air inlet 11.

[0033] The first shell 1A and the second shell 1B are each provided with the accommodating cavity 16 at the free end, and the air inlet cavity 13 is arranged at the position of the connection end of the first shell 1A and the second shell 1B corresponding to the air inlet 11, and the accommodating cavity 16 is arranged at the free end of the first shell 1A and the second shell 1B, so that the structure is reasonably distributed.

[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, and the wearing is more comfortable. The air is blown to the heat dissipation channel 18 after passing through the air duct 15, which does not affect the air force and air effect of the air flowing through the air duct 15 and the air outlet 12. Moreover, the heat dissipation channel 18 is arranged downstream of the air duct 15, which is conducive to relieving the wind blockage caused by excessive air volume and avoiding noise caused by excessive air volume. The temperature guide 22 abuts against the neck of the human body, and the air outlet 17 faces away from the neck of the human body. The temperature guide 22 directly adjusts the neck of the human body in contact therewith, and the hot air discharged from the air outlet 17 after passing through the heat dissipation channel 18 faces away from the neck of the human body, and the user has a good experience.

[0035] In one embodiment, as shown in Figures 1 to 5 The mounting member 21 and the temperature guide 22 extend along the length direction of the shell 1, so that the temperature guide 22 has a larger area in contact with the neck of the human body, and the user has a better experience. Figures 1 to 3 As shown in The mounting member 21 and the temperature guide 22 extend along the length direction of the shell 1, so that the temperature guide 22 has a larger area in contact with the neck of the human body, and the user has a better experience.

[0036] In one embodiment, as shown in Figures 1 to 5 The portable fan further comprises a power supply 5 and a control panel 6. The power supply 5 is arranged in the accommodating cavity 16, and the braking assembly comprises a motor 3 and a fan 4. The motor 3, the power supply 5 and the temperature guide 23 are electrically connected with the control panel 6. The motor 3 is a three-phase high-speed motor, which can provide high-speed and stable rotation to ensure the air volume, air pressure and blowing effect.

[0037] Moreover, the fan 4 is an axial or inclined fan. The axial or inclined fan is relatively small and compact compared with the centrifugal fan, which is conducive to reducing the volume of the fixed cavity 14, so that the shell 1 is small and compact as a whole.

[0038] In one embodiment, as shown in Figures 1 to 5 The cross section of the fixed cavity 14 is circular, and the air duct 15 has a portion with a reduced cross section from the direction away from the fixed cavity 14. Through the portion with a reduced cross section, the air pressure of the air generated by the braking assembly is improved, so that the air can flow more smoothly to the downstream end of the air duct 15, and the backflow phenomenon is avoided.

[0039] The above detailed description is merely exemplary in nature and is not intended to limit the scope and application of the application claimed. Thus, any equivalent technology which directly or indirectly relates to the described technology is intended to come within the scope of the claimed application.
