Detailed Embodiment

[0028] The following further describes the present application in detail with reference to the attached Figures 1-5 drawings.

[0029] An embodiment of the present application discloses a handheld fan 100.

[0030] Reference Figure 1 、 Figure 2 and Figure 4 The handheld fan 100 according to an embodiment of the present application includes a housing 1, a blower mechanism 2, a mosquito repellent member 3, a cooling member 4, and a power supply 5. The housing 1 defines an installation space 11. The outer peripheral wall of the housing 1 is provided with a first air outlet 12 and a through hole 13. Both the first air outlet 12 and the through hole 13 communicate with the installation space 11 and are configured as through holes.

[0031] In some specific embodiments, along the first direction of the housing 1, the right end wall of the housing 1 is provided with a first air outlet 12, and along the second direction of the housing 1, the rear end wall of the housing 1 is provided with a through hole 13. The first direction of the housing 1 can refer to Figure 2 The left and right directions in the second direction of the housing 1 can refer to Figure 4 The front-to-back direction.

[0032] The hair blowing mechanism 2 is arranged in the shell 1 and is opposite to the first air outlet 12. The hair blowing mechanism 2 is used to blow gas to the first air outlet 12. The refrigeration component 4 is arranged in the first air outlet 12. The refrigeration component 4 is used for cooling and is suitable for contact with the skin. The mosquito repellent component 3 is arranged in the shell 1 and is opposite to the through hole 13. The mosquito repellent component 3 is used to emit sound waves to repel mosquitoes. The power supply 5 is arranged in the shell 1. The power supply 5 is electrically connected to the hair blowing mechanism 2, the mosquito repellent component 3 and the refrigeration component 4.

[0033] Specifically, the power supply 5 supplies power to the blowing mechanism, the mosquito repellent component 3 and the refrigeration component 4, so that the blowing mechanism 2, the mosquito repellent component 3 and the refrigeration component 4 all start working, and the blowing mechanism 2 blows gas toward the first air outlet 12, and the gas is cooled by the refrigeration component 4. The cooled gas takes away the heat from the skin surface, thereby improving the cooling effect of the handheld fan 100, and further improving the user experience of the handheld fan 100.

[0034] The mosquito repellent element 3 emits sound waves toward the through hole 13, and the sound waves pass through the through hole 13 into the external environment. The sound waves repel mosquitoes in the area near the shell 1, thereby increasing the mosquito repellent range of the handheld fan 100. After being bitten by a mosquito, the itching sensation of the bitten area can be reduced by applying ice to the bitten area using the refrigeration element 4.

[0035] Furthermore, the user can also use the refrigeration component 4 to apply ice to the skin to cool it down, thereby quickly taking away the heat on the skin surface, which can further improve the cooling effect of the handheld fan 100.

[0036] Furthermore, there are multiple through-holes 13, and the multiple through-holes 13 are arranged at intervals in the circumferential direction of the housing 1. The mosquito repellent member 3 emits sound waves to all the multiple through-holes 13, thereby further increasing the mosquito repellent range of the handheld fan 100.

[0037] In some specific embodiments, the mosquito repellent member 3 is preferably an ultrasonic mosquito repellent device, and the mosquito repellent member 3 realizes the mosquito repellent function by sending ultrasonic waves with a preset frequency to the external environment.

[0038] In some specific embodiments, the cooling member 4 is preferably a thermoelectric cooler.

[0039] Thus, by the mosquito repellent member 3 emitting sound waves to the through-holes 13, the sound waves drive away the mosquitoes in the area near the housing 1, and after being bitten by mosquitoes, the cooling member 4 is used to ice the bitten area. Compared with the prior art, the sound waves can be transmitted to any area near the housing 1, thereby increasing the mosquito repellent range of the handheld fan 100, and using the cooling member 4 for icing can reduce the itching sensation of the bitten area, thereby improving the user's outdoor activity experience and further improving the use experience of the handheld fan 100.

[0040] Refer to Figure 1 、 Figure 2 and Figure 4 In some embodiments of the present application, a first flow dividing member 121 is provided at the first air outlet hole 12. The first flow dividing member 121 is provided with a plurality of first flow dividing holes 1211. The first flow dividing holes 1211 are configured as through holes, and the plurality of first flow dividing holes 1211 are arranged at intervals in the circumferential direction of the first flow dividing member 121. The blowing mechanism 2 is disposed opposite to the first flow dividing holes 1211, and the cooling member 4 is disposed on the end wall of the first flow dividing member 121 away from the blowing mechanism 2, and the cooling member 4 is disposed opposite to all the plurality of first flow dividing holes 1211.

[0041] Along the first direction of the housing 1, the blowing mechanism 2 is located on the left side of the first flow dividing member 121, and the cooling member 4 is disposed on the right end wall of the first flow dividing member 121.

[0042] Specifically, the blowing mechanism 2 blows air to the first air outlet hole 12, and the air is divided by the plurality of first flow dividing holes 1211 so that the air can be evenly distributed and the air is softer, thereby avoiding the air concentrating in the same area and affecting the use experience of the handheld fan 100, and the air flowing out of the first flow dividing holes 1211 is cooled by the cooling member 4.

[0043] Furthermore, the blowing mechanism 2 can be disposed on the end wall of the first flow dividing member 121 close to the installation space 11.

[0044] Refer to Figure 1 and Figure 2, in some embodiments of the present application, a transfer member 1212 is provided on the end wall of the first flow divider 121 away from the blowing mechanism 2. The transfer member 1212 is opposite to a plurality of first flow holes 1211. The transfer member 1212 defines a refrigeration gap 1213. A refrigeration member 4 is disposed in the transfer member 1212, and the refrigeration member 4 is in abutting cooperation with the inner peripheral wall of the refrigeration gap 1213. The refrigeration member 4 is used to refrigerate the transfer member 1212, and the area of the transfer member 1212 is larger than the area of the refrigeration member 4.

[0045] Specifically, the refrigeration member 4 is disposed in the transfer member 1212, and the refrigeration member 4 abuts against the inner peripheral wall of the refrigeration gap 1213. The refrigeration member 4 refrigerates the transfer member 1212, and the area of the transfer member 1212 is larger than the area of the refrigeration member 4, so that the cold quantity of the refrigeration member 4 can be diffused to a larger area. The gas flows out of the first flow holes 1211 and contacts the transfer member 1212, and the transfer member 1212 refrigerates the gas. Thus, a small-area refrigeration member 4 can be used to refrigerate a large range of gas, and further, the manufacturing cost of the handheld fan 100 can be reduced.

[0046] In some specific embodiments, the shape of the refrigeration member 4 and the shape of the transfer member 1212 can both be configured as circular, and the diameter dimension of the transfer member 1212 is larger than the diameter dimension of the refrigeration member 4.

[0047] Furthermore, the transfer member 1212 is made of a metal material.

[0048] Refer to Figure 2 and Figure 5 , in some embodiments of the present application, the housing 1 is provided with a second air outlet hole 14. Along the first direction of the housing 1, the second air outlet hole 14 is opposite to the first air outlet hole 12 and the blowing mechanism 2. Specifically, the first air outlet hole 12 is located on the right side of the blowing mechanism 2, and the second air outlet hole 14 is located on the left side of the blowing mechanism 2. The blowing mechanism 2 is adapted to blow gas to the first air outlet hole 12 or the second air outlet hole 14.

[0049] Specifically, when the user needs to use the refrigeration member 4 to refrigerate the gas, the blowing mechanism 2 blows gas to the first air outlet hole 12. When the user does not need the refrigeration member 4 to refrigerate the gas, the blowing mechanism 2 blows gas to the second air outlet. The user can control the blowing mechanism 2 to blow gas to the first air outlet hole 12 or the second air outlet hole 14 according to the usage requirements, so as to improve the usage experience of the handheld fan 100.

[0050] Refer to Figure 2 and Figure 5, in some embodiments of the present application, the second air outlet 14 is provided with a second flow dividing member 141. The second flow dividing member 141 is provided with a plurality of second flow dividing holes 1411. The second flow dividing holes 1411 are configured as through holes. The plurality of second flow dividing holes 1411 are arranged at intervals along the radial direction of the second flow dividing member 141. The blowing mechanism 2 faces the second flow dividing holes 1411.

[0051] The blowing mechanism 2 blows gas towards the second air outlet 14. The gas is divided by the plurality of second flow dividing holes 1411, so that the gas can be evenly distributed along the radial direction of the second flow dividing member 141, making the blown air more diffused and having a larger coverage area. Thus, the cooling effect of the fan can be improved and the mosquito repellent ability can be enhanced. Moreover, since the gas flows more smoothly after passing through the second flow dividing holes 141, it helps to avoid the gas being too concentrated in the same area, thereby improving the comfort of using the handheld fan 100.

[0052] Refer to Figure 2 and Figure 4 , in some embodiments of the present application, the blowing mechanism 2 includes a driving member 21, a blowing member 22 and an elastic member 23.

The driving member 21 is used to drive the blowing member 22 to drive the plurality of fan blades 221 to rotate, so that the blowing member 22 blows gas towards the first air outlet 12.

[0053] Specifically, the driving member 21 drives the blowing member 22 to rotate. The blowing member 22 drives the fan blades 221 to rotate to form a strong air flow. Then the fan blades 221 push the gas towards the first air outlet 12 or the second air outlet 14, thereby achieving the technical effect of the blowing mechanism 2 blowing gas towards the first air outlet 12 or the second air outlet 14.

[0054] In some specific embodiments, when the driving member 21 drives the blowing member 22 to rotate clockwise around the central axis of the driving member 21, the fan blades 221 push the gas towards the first air outlet 12. When the driving member 21 drives the blowing member 22 to rotate counterclockwise around the central axis of the driving member 21, the fan blades 221 push the gas towards the second air outlet 14.

[0055] Moreover, the elastic member 23 is elastically deformably arranged between the blowing member 22 and the elastic member 23. When the blowing member 22 is subjected to vibration or wind resistance change, the elastic member 2s can buffer the blowing member 22, thereby reducing mechanical vibration and further improving the durability and comfort of using the handheld fan 100.

[0056] In some specific embodiments, the driving member 21 is preferably a motor, and the elastic member 23 is preferably a spring.

[0057] Refer toFigure 2 , in some embodiments of the present application, the handheld fan 100 further includes: a start switch 6.

[0058] Specifically, the user controls the power source 5 to supply power to the blowing mechanism 2, the mosquito repellent member 3, and the refrigeration member 4 through the start switch 6, so that the blowing mechanism 2, the mosquito repellent member 3, and the refrigeration member 4 are all started to work. The user controls the power source 5 to stop supplying power to the blowing mechanism 2, the mosquito repellent member 3, and the refrigeration member 4 through the start switch 6, so that the blowing mechanism 2, the mosquito repellent member 3, and the refrigeration member 4 all stop working, thereby saving energy.

[0059] By using the start switch 6 to control the power source 5 to supply power to and stop supplying power to the blowing mechanism 2, the mosquito repellent member 3, and the refrigeration member 4, it is possible to realize one-key control of the start or stop of the handheld fan 100, and energy can be saved to extend the battery life.

[0060] In some specific embodiments, the start switch 6 is preferably a push-pull switch.

[0061] Refer to Figure 2 , in some embodiments of the present application, the handheld fan 100 may further include: a regulating member 7 and a controller.

The regulating member 7 is arranged inside the housing 1, and the regulating member 7 is opposite to the second avoidance hole 16. When the regulating member 7 is rotated, a first control signal is generated. When the regulating member 7 is pressed, a second control signal is generated. The regulating member 7, the blowing mechanism 2, the mosquito repellent member 3, and the refrigeration member 4 are all communicatively connected to the controller. The controller is used to control the blowing mechanism 2 to adjust the blowing speed of the gas according to the first control signal, and is used to control the blowing mechanism 2 and / or the mosquito repellent member 3 and / or the refrigeration member 4 to start or stop working according to the second control signal.

[0062] In some specific embodiments, the regulating member 7 is preferably an encoder.

[0063] Specifically, the user twists the regulating member 7 to control the blowing mechanism 2 to adjust the blowing speed of the gas, and the user presses the regulating member 7 to control the blowing mechanism 2 and / or the mosquito repellent member 3 and / or the refrigeration member 4 to stop or start working. The user can adjust the handheld fan 100 according to the usage requirements in different environments, thereby improving the usage experience of the handheld fan 100.

[0064] In some specific embodiments, when the user twists the control member 7 in the clockwise direction, the controller controls the blowing mechanism 2 to increase the blowing speed of the gas. When the user twists the control member 7 in the counterclockwise direction, the controller controls the blowing mechanism 2 to decrease the blowing speed of the gas. It should be noted that the controller controls the rotational speed of the driving member 21 to drive the blowing member 22 to rotate, so as to adjust the blowing speed of the gas.

[0065] In some specific embodiments, when the user presses the control member 7 for the first time, the blowing mechanism 2 starts to work. When the user presses the control member 7 for the second time, the refrigerating member 4 starts to work. When the user presses the control member 7 for the third time, the mosquito repellent member 3 starts to work.

When the controller controls the mosquito repellent member 3 to start working according to the second control signal, the second light emitting member 8 starts to work, and the second light emitting member 8 projects the second preset pattern onto the light transmissive member 10. When the controller controls the refrigerating member 4 to start working according to the second control signal, the third light emitting member 8 starts to work, and the third light emitting member 8 projects the third preset pattern onto the light transmissive member 10.

[0070] When the controller controls the blowing mechanism 2 to stop working according to the second control signal, the first light-emitting member 8 stops working. When the controller controls the mosquito repellent member 3 to stop working according to the second control signal, the second light-emitting member 8 stops working. When the controller controls the refrigerating member 4 to stop working according to the second control signal, the third light-emitting member 8 stops working.

[0071] When the controller controls the blowing mechanism 2 and / or the mosquito repellent member 3 and / or the refrigerating member 4 to start working according to the second control signal, the controller controls the corresponding one of the light-emitting members 8 to start working according to the second control signal. The light-emitting member 8 projects the corresponding preset pattern onto the light-transmitting member 10. The user can judge whether the blowing mechanism 2, the mosquito repellent member 3 and the refrigerating member 4 start working by observing whether the preset pattern lights up, thereby improving the use experience of the handheld fan 100.
