[0030] See also Figures 1 to 3The present application provides a multifunctional wristband fan, comprising a housing 10, a wristband 20, a fan 30, and an intercom module 40. The housing 10 is provided with an air inlet 11 and an air outlet 12, and the fan 30 is rotatably disposed in the housing 10 to guide the air from the air inlet 11 to the air outlet 12. The wristband 20 is connected to the housing 10 and is used to be worn on a human wrist. The intercom module 40 is used for the intercom interactive function of the multifunctional wristband fan.

[0031] Understandably, the existence of the intercom interaction function allows the multi-functional wristband fan to be used as an intercom, improving the practical performance of the fan. The fan can be used in a variety of usage scenarios such as indoor blowing, outdoor play, intercom interaction, etc., meeting the needs of multiple scenarios. Secondly, compared with traditional intercoms, the existence of a wristband is not only convenient to carry, but also makes it less likely to be lost.

[0032] Understandably, since the fan is disposed in the housing, air can only be discharged from the air outlet position, and thus, when the fan is rotated horizontally, it can still meet the requirements of a special air outlet direction, thereby reducing the overall height of the fan.

[0033] See also Figure 2 The intercom module 40 includes a receiver module 41, a speaker module 42 and a control module 43. The control module 43 is disposed in the housing 10, and the receiver module 41, the speaker module 42 and the control module 43 are electrically connected.

[0034] Exemplarily, the control module 43 includes a controller 431 and a wireless communication module, and the wireless communication module is used to receive and transmit intercom communication signals. The wireless communication module preferably uses an antenna. The controller 431 can use a circuit board or a PLC control board, etc.

[0035] Exemplarily, the receiving module 41 is used to receive sound and convert it into an audio signal, and preferably a microphone can be used. The speaker module 42 is used to convert the audio signal into sound, and preferably a speaker can be used.

[0036] It should be noted that the operation principles of the receiver module 41, speaker module 42, controller 431, and wireless communication module involved in this embodiment are all prior art, so they will not be repeated. The operation process and principle of the intercom module 40 to realize the intercom function are also prior art, so they will not be repeated.

[0037] Preferably, the control module 43, the receiver module 41, and the speaker module 42 are all arranged in the housing 10, and the overall appearance of the wristband fan is more beautiful. The receiver module 41 and the speaker module 42 are preferably integrated with the control module 43. Of course, in other embodiments, the receiver module 41 and the speaker module 42 may not be integrated with the control module 43, but may be separately arranged at different positions in the housing.

[0038] Further, see Figure 3 The intercom module 40 further includes an intercom button 44. The intercom button 44 is disposed on the housing 10 and is used to open or close the intercom module 40 in response to the applied force.

[0039] It can be understood that a contact is provided on the controller 431 at a position corresponding to the intercom button 44. By pressing the intercom button 44, pressure can be applied to the contact, so that the controller 431 issues relevant instructions to control the intercom module 40 to be turned on or off. The method of receiving and sending instructions based on the circuit board or PLC control board is an existing technology, so it will not be repeated here.

[0040] Furthermore, the intercom module 40 further includes an indicator light 45, which is electrically connected to the control module 43. When the control module 43 controls the intercom module 40 to be turned on, the indicator light 45 can be controlled to light up, so that the user can clearly distinguish whether the intercom mode is in the turned-on state.

[0041] Exemplarily, the indicator light 45 preferably adopts an LED lamp bead.

[0042] Furthermore, a receiver port 46 is provided on the housing 10 , and the receiver port 46 is arranged corresponding to the receiver module 41 , so that sound is transmitted from the outside of the housing 10 to the receiver module 41 .

[0043] Preferably, the receiver port 46 is a plurality of circular through holes provided on the housing 10 , and the positions of the receiver module 41 and the receiver port 46 can be selected according to actual needs.

[0044] Furthermore, a speaker port 47 is provided on the housing 10 , and the speaker port 47 is arranged corresponding to the receiver module 41 , so that sound is transmitted from the inside of the housing 10 to the outside of the housing 10 .

[0045] Preferably, the sound outlet 47 is a plurality of circular through holes provided on the housing 10 , and the positions of the sound module 42 and the sound outlet 47 can be selected according to actual needs.

[0046] In this embodiment, a power source 51 is disposed in the housing 10, and the control module 43 is electrically connected to the power source 51, and the control module is powered by the power source 51. The power source 51 can be a nickel-cadmium battery, a lithium battery, or the like.

[0047] Specifically, the fan 30 includes blades 31 and a driving member 32. The blades 31 are arranged around the driving member 32, and the driving shaft of the driving member 32 is connected to the blades 31. With the axis of the height direction Z of the housing 10 as the center line, the driving member 32 is used to drive the blades 31 to rotate circumferentially around the center line.

[0048] It can be understood that the fan blades 31 are arranged around the periphery of the driving member 32, so that the driving member 32 and the fan blades 31 only occupy the height of the fan blades 31, the space occupied is small, and the overall structure is compact.

[0049] Exemplarily, the driving member 32 may be a micro motor, a small brushed motor, etc., which are existing technologies and can be directly purchased, and the structure is not described in detail.

[0050] See also Figure 3 The housing 10 is also provided with an on / off switch 53 , the on / off switch 53 is electrically connected to the control module 43 , and the driving member 32 is electrically connected to the control module 43 .

[0051] It can be understood that the on-off switch 53 can be a button purchased on the market. A contact is set on the controller at a position corresponding to the on-off switch 53. Pressing the on-off switch 53 can apply pressure to the contact, so that the controller sends relevant instructions to control the drive component to open or close, and then control the fan to start or stop.

[0052] Preferably, along the height direction Z of the housing 10, the power supply is located above the fan 30, so as to make full use of the space and make the overall structure more compact.

[0053] Furthermore, along the height direction Z of the housing 10 , the air inlet 11 is disposed at the lower portion 10 a of the housing 10 . Along the width direction X or the length direction Y of the housing 10 , the air outlet 12 is disposed at the side portion 10 b of the housing 10 .

[0054] That is, the air outlet 12 is arranged on one side along the length direction Y of the shell 10, or the air outlet 12 is arranged on one side along the length direction Y of the shell 10, so as to satisfy that the air outlet direction is parallel to the wrist or has a certain angle, but not vertical.

[0055] In this embodiment, the air outlet 12 is disposed on one side along the length direction Y of the housing 10 .

[0056] It can be understood that by setting the air outlet at the side position and the wristband at the lower part of the shell 10, when the fan is worn on the wrist, the air outlet direction is parallel to the wrist or has a certain angle. Only by raising the arm normally, the fan on the wrist can blow towards the face or body part without twisting the wrist. It is easy to operate and very comfortable to use.

[0057] Furthermore, along the height direction Z of the housing 10, the wristband 20 is connected to the lower part 10a of the housing 10. The fan 30 is used to introduce airflow from the air inlet and blow it out from the air outlet 12. The setting direction of the air outlet 12 is the air outlet direction of the fan 30, and then the air outlet direction of the fan 30 is basically parallel to the wrist. Just raise the arm normally, and the fan 30 on the wrist can blow to the face or body parts without twisting the wrist. It is easy to operate and comfortable to use.

[0058] Of course, the wristband 20 is not limited to being worn on the wrist. According to usage requirements, the wristband 20 can also be tied to items such as a crib, a chair, a toy, etc., as long as it can blow air toward the human body.

[0059] See also Figure 2 In one embodiment, a recessed portion 72 is provided at the lower portion of the shell 10 near the wristband 20 , the recessed portion 72 extends from the outside of the shell 10 to the inside of the shell 10 , and an opening is provided on the side of the recessed portion 72 near the outside of the shell 10 .

[0060] That is, the inner wall of the recessed portion 72 and the wristband 20 are arranged to form a storage cavity 70. One side of the storage cavity 70 is set as an opening, and then the storage cavity 70 can be placed with mosquito repellent sheets, aromatherapy, essential oils and other items.

[0061] Understandably, during the flow of air, the odors emitted by the above-mentioned items will be brought out and blown out from the air outlet 12, so that the fan 30 not only cools down but also has the functions of repelling mosquitoes and adding fragrance, thereby improving the practical performance of the fan 30.

[0062] Furthermore, the recessed portion 72 is provided with a plurality of notches 71, which are arranged at intervals along the circumference of the recessed portion 72. One side of the notch 71 is connected to the air inlet 11, and the other side of the notch 71 is connected to the storage cavity 70, thereby achieving communication between the storage cavity 70 and the air inlet 11.

[0063] In this embodiment, the wristband 20 is detachably connected to the housing 10, and the wristband 20 seals the opening while being detachably connected to the housing 10. In this structure, there is no need to set up a separate cover to seal the opening, which simplifies the structure, makes the overall structure more compact, and reduces the manufacturing cost. In addition, if the wristband 20 is damaged, the wristband 20 can be replaced separately, thereby extending the service life of the entire multifunctional wristband fan.

[0064] Furthermore, the detachable connection may be in the form of screw connection, plug connection, clip connection, riveting connection, etc., and screw connection is preferably used in this embodiment.

[0065] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
