The other two electrical pins 151 are electrically connected to the positive and negative terminals of the light-emitting element 3, respectively, to control whether the light-emitting element 3 is working or not.

[0049] When the connector 119 formed by the first socket 117 and the second socket 122 is plugged into the heating element 102, the four electric needles 151 are electrically connected to the heating element 102, so that the heating element 102 can supply power to the motor 21 and the light-emitting element 3 through the four electric needles 151. The motor 21 can drive the fan wheel 22 to rotate, and the light-emitting element 3 can emit light.

[0050] refer to Figures 5 to 8 The heating component 102 includes a housing 4 and a main control board 5, a heating element 6 and a battery 7 disposed on the housing 4. The heating element 6 and the battery 7 are electrically connected to the main control board 5. The battery 7 can supply power to the main control board 5 so that the main control board 5 can control the heating element 6 to heat up. The heating element 6 is in contact with the housing 4 and can heat up the housing 4. The user can put their hands on the housing 4 to warm up.

[0051] The housing 4 includes a first body 41, a second body 42, a third body 43 and a fourth body 44 that are sequentially snapped together, wherein the main control board 5 and the battery 7 are encapsulated between the second body 42 and the third body 43.

[0052] The first body 41 has a plurality of first hooks 411 on its periphery, and the second body 42 has a plurality of first slots 421 on its periphery near the first body 41. Each first hook 411 can engage with the corresponding first slot 421 so that the first body 41 and the second body 42 can engage.

[0053] The second body 42 has a plurality of second hooks 422 arranged along its periphery on the side near the third body 43, and the third body 43 has a plurality of second slots 431 opened along its periphery on the side near the second body 42. Each second hook 422 can engage with the corresponding second slot 431 so that the third body 43 engages with the second body 42.

[0054] The third body 43 has multiple third slots 432 along its periphery, and the fourth body 44 has multiple third hooks 441 along its periphery on the side close to the third body 43. Each third hook 441 can engage with the corresponding third slot 432 so that the third body 43 and the fourth body 44 can engage.

[0055] The second body 42 has a first notch 423, and the third body 43 has a second notch 433. When the second body 42 and the third body 43 are engaged, the first notch 423 and the second notch 433 cooperate to form a plug-in groove 425. The plug-in groove 425 is used for detachable insertion with the plug-in connector 119 of the fan head 101. When the plug-in groove 425 is inserted into the plug-in connector 119, the main control board 5 is electrically connected to the four electrical pins 151 of the fan head 101 to supply power to the four electrical pins 151, so that the motor 21 and the light-emitting element 3 of the fan head 101 can be in working condition.

[0056] refer to Figure 5 and Figure 6 The second body 42 also has a third notch 424, which is located within the first notch 423. The third notch 424 is used for removably engaging the dust plug 8. After the fan head 101 is detached from the insertion slot 425, the dust plug 8 can be inserted into the third notch 424 to seal the insertion slot 425. This not only waterproofs and dustproofs the insertion slot 425, but also ensures that the surface of the dust plug 8 is flush with the surface of the second body 42 when inserted into the third notch 424, making the entire housing 4 of the heating element 102 appear flat and aesthetically pleasing. When it is necessary to reconnect the fan head 101, the dust plug 8 can be removed again to expose the insertion slot 425.

[0057] The second body 42 has a receiving cavity 424 for accommodating the main control board 5 and the battery 7. The bottom of the insertion slot 425 has four positioning holes 426, each of which connects the receiving cavity 424 and the insertion slot 425.

[0058] refer to Figure 9The main control board 5 has four contact pieces 51 arranged linearly, and the four contact pieces 51 correspond to the four positioning holes 426. When the connector 119 of the fan head 101 is inserted into the connector slot 425, the four electric pins 151 on the connector 119 can simultaneously pass through the four positioning holes 426 to electrically contact the four contact pieces 51, so that the main control board 5 simultaneously supplies power to the motor 21 and the light-emitting element 3 of the fan head 101.

[0059] There are two heating elements 6. One heating element 6 is located on the second body 42 and is in contact with the first body 41. The other heating element 6 is located on the third body 43 and is in contact with the fourth body 44. When the two heating elements 6 are heating, they can respectively drive the first body 41 and the fourth body 44 to heat up, so that the outer surface of the entire shell 4 is in a heated state, thereby warming the user's hands.

[0060] Both the second body 42 and the third body 43 have holes 427, through which the two heating elements 6 can be wired and electrically connected to the main control board 5.

[0061] The second body 42 has a second magnetic suction member 45 located near the insertion slot 425 in the accommodating cavity 424. When the connector 119 of the fan head 101 is inserted into the insertion slot 425, the second magnetic suction member 45 can be magnetically attracted to the first magnetic suction member 14, so that the connector 119 of the fan head 101 can be inserted into the insertion slot 425 more stably. The four electric pins 151 of the connector 119 are electrically connected to the four contact pieces 51 on the main control board 5, and poor contact is not easy to occur.

[0062] It is understood that in other embodiments, magnetic adsorption can also be achieved by providing a magnetic adsorption component on only one of the fan head 101 and the heating component 102, while the housing of the other is made of metal.

[0063] The first body 41 is also provided with a display screen 412, which is electrically connected to the main control board 5 and is used to display the remaining power of the battery 7 and the blowing speed of the fan head 101, such as speed 1, speed 2 and speed 3.

[0064] The first body 41 is also equipped with a heating control button 413 and a fan control button 414, both of which are electrically connected to the main control board 5. The heating control button 413 is used to control the opening and closing of the heating element 6, acting as the on / off switch for the hand warmer function. The fan control button 414 is used to control the speed of the motor 21; the higher the speed, the greater the rotation speed of the motor 21 and the stronger the airflow.

[0065] The first body 41 has a charging port 415, which is used to connect to an external power source via a charging cable to charge the battery 7.

[0066] refer to Figure 1 and Figure 2 The bottom surface of the positioning base 103 is flat, which makes it easy to place stably on a support surface such as a table or the ground.

[0067] The top of the positioning base 103 has a positioning groove 8, which is used for detachable insertion with the heating component 102. When the positioning groove 8 is inserted with the heating component 102, the end of the heating component 102 away from the positioning base 103 is connected to the fan head 101. The fan head 101 can then be fixed on a support surface such as a desktop or the ground through the heating component 102 and the positioning base 103, so that the user can use the fan head 101 to blow air for heat dissipation without holding the heating component 102.

[0068] When the heating element 102 is removed from the positioning slot 8, the user can insert the fan head 101 into the heating element 102, hold the heating element 102, and use the fan head 101 to blow air for heat dissipation. At this time, the heating element 102 is equivalent to a handle, which the user can hold and use the fan head 101 to blow air.

[0069] The positioning base 103 is also provided with a support groove 9. The side of the support groove 9 near the positioning groove 8 can be used for electronic devices such as mobile phones or tablets to lean against. The side of the support groove 9 away from the positioning groove 8 has a limiting protrusion 91. The limiting protrusion 91 is used to limit the electronic device placed in the support groove 9 so that the electronic device is placed stably and it is convenient for users to use the electronic device to watch TV.

[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0071] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications, substitutions, and improvements without departing from the concept of this utility model, and these should all be covered within the protection scope of this utility model.
