[0037] Both the left half shell 11 and the right half shell 12 have air outlets 111. The left half shell 11 is recessed with a movable cavity 112 facing away from the right half shell 12. The movable cavity 112 is used to accommodate the blower assembly 2 so that the blower assembly 2 can drive the airflow to blow out to the outside of the outer shell 1 through the air outlet 111 to blow air to the user.

[0038] The left half-shell 11 has a slot (not shown in the figure) along its periphery, and the right half-shell 12 has a hook 121 along its periphery. Each hook 121 can be detachably engaged with the corresponding slot, so that the left half-shell 11 and the right half-shell 12 can be detachably engaged. When the left half-shell 11 and the right half-shell 12 are engaged, the right half-shell 12 can encapsulate the blower assembly 2 in the movable cavity 112. In other embodiments, the left half-shell 11 can also have a hook 121 and the right half-shell 12 can have a slot, which can also achieve detachable engagement between the left half-shell 11 and the right half-shell 12.

[0039] A fixing cavity 113 is provided on the side of the left half shell 11 away from the right half shell 12. The fixing cavity 113 is hollow with openings at both ends. One end is connected to the movable cavity 112, and the other end is close to the rear cover 13. Multiple snap-fit ​​slots 114 and multiple elastic clips 115 are provided. The multiple snap-fit ​​slots 114 and multiple elastic clips 115 are all arranged around the periphery of the fixing cavity 113. Each elastic clip 115 is located in the corresponding snap-fit ​​slot 114 and can deform within the corresponding snap-fit ​​slot 114.

[0040] The elastic clip 115 is made of elastic plastic and has a certain elastic deformation capability. In its natural state, the elastic clip 115 can limit the blower assembly 2 located in the fixed cavity 113, preventing the blower assembly 2 from detaching from the fixed cavity 113. The user can apply force to the elastic clip 115 to drive multiple elastic clips 115 to deform in opposite directions, thereby unlocking the blower assembly 2 located in the fixed cavity 113 and disassembling the blower assembly 2.

[0041] In addition to providing space for the elastic clip 115 to deform and move, the snap-fit ​​groove 114 also serves to removably attach the snap-fit ​​back cover 13.

[0042] The back cover 13 has multiple snap-fit ​​pieces 131 arranged along its periphery. The position of each snap-fit ​​piece 131 corresponds to the snap-fit ​​groove 114, so that each snap-fit ​​piece 131 can be snapped into the corresponding snap-fit ​​groove 114, so that the back cover 13 can encapsulate the blower assembly 2 and the fill light 3.

[0043] The fixed cavity 113 has a limiting plate 116 on the side away from the rear cover 13. The limiting plate 116, together with the elastic clip 115, limits the blowing assembly 2 of the fixed cavity 113.

[0045] The blower assembly 2 includes a drive motor 21 and a fan blade 22. The drive motor 21 is located in the fixed cavity 113, and the fan blade 22 is rotatably located in the movable cavity 112. The drive motor 21 is connected to the fan blade 22 and can drive the fan blade 22 to rotate in the movable cavity 112 to drive the air to form a flowing airflow. The airflow is blown out through the air outlet 111 of the right half shell 12 to form a blower and dissipate heat for the user.

[0046] A positioning post 211 is provided on the side of the drive motor 21 facing away from the fan blade 22. A positioning hole 31 is provided through the center of the supplementary light 3. The supplementary light 3 is inserted into the positioning post 211 through the positioning hole 31 to pre-position the supplementary light 3. Then, it is snapped into the snap-fit ​​groove 114 by the back cover 13 to encapsulate the supplementary light 3.

[0047] The back cover 13 is made of a light-transmitting material, so that the light emitted by the fill light 3 can be transmitted through the back cover 13 to the outside, providing illumination for the user.

[0048] The bottom of the left half-shell 11 has a first socket 117, and the bottom of the right half-shell 12 has a second socket 122. The first socket 117 has a screw hole 118, and the second socket 122 has a stud 123. When the left half-shell 11 and the right half-shell 12 are engaged, the stud 123 is inserted into the screw hole 118. A screw can be passed through the screw hole 118 and threaded into it to connect the first socket 117 and the second socket 122. After connection, the first socket 117 and the second socket 122 form a connector 119. Figure 2 (As shown).

[0049] refer to Figure 4 The second socket 122 has a mounting slot 125 and pinholes 126, with the pinholes 126 connecting the mounting slot 125 to the outside. The mounting slot 125 is used to store an electrical connector 15, which includes a first circuit board 151 and four electrical pins 151 disposed on the first circuit board 151. There are four pinholes 126, each allowing one of the four electrical pins 151 to pass through to the outside. Two of the electrical pins 151 are electrically connected to the positive and negative terminals of the drive motor 21, respectively, to control the operation of the drive motor 21. The other two electrical pins 151 are electrically connected to the positive and negative terminals of the supplementary light 3, respectively, to control the operation of the supplementary light 3.

[0050] When the connector 119 formed by the first socket 117 and the second socket 122 is plugged into the handle 102, the four electric pins 151 are electrically connected to the handle 102, so that the handle 102 can supply power to the drive motor 21 and the fill light 3 through the four electric pins 151. The drive motor 21 can drive the fan blade 22 to rotate, and the fill light 3 can emit light.

[0051] refer to Figures 5 to 8 The handle 102 includes a housing 4 and a circuit 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 circuit board 5. The battery 7 can supply power to the circuit board 5 so that the circuit board 5 can control the heating element 6 to generate heat. 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 them.

[0052] 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 circuit board 5 and the battery 7 are encapsulated between the second body 42 and the third body 43.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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 insertion slot 425. The insertion slot 425 is used for detachable insertion with the connector 119 of the blower head 101. When the insertion slot 425 is inserted with the connector 119, the circuit board 5 is electrically abutted against the four electrical pins 151 of the blower head 101 to supply power to the four electrical pins 151, so that the drive motor 21 of the blower head 101 and the supplementary light 3 can be in working condition.

[0057] 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 the removable snap-fit ​​of the dust plug 8. After the blower head 101 is detached from the insertion slot 425, the dust plug 8 can be snapped 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 it is snapped into the third notch 424, making the entire housing 4 of the handle 102 look flat and aesthetically pleasing. When it is necessary to reconnect the blower head 101, the dust plug 8 can be removed again to expose the insertion slot 425.

[0058] The second body 42 has a receiving cavity 424 for accommodating the circuit 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.

[0059] refer to Figure 9The circuit board 5 has four conductive plates 51 arranged linearly, and the four conductive plates 51 correspond to the four positioning holes 426. When the connector 119 of the blower head 101 is inserted into the connector slot 425, the four electrical pins 151 on the connector 119 can simultaneously pass through the four positioning holes 426 to electrically contact the four conductive plates 51, so that the circuit board 5 simultaneously supplies power to the drive motor 21 of the blower head 101 and the supplementary light 3.

[0060] 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 heated, 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.

[0061] 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 circuit board 5.

[0062] The second body 42 has a second magnetic suction member 45 located near the insertion slot 425 in the accommodating cavity 424. When the insertion member 119 of the blower 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 insertion member 119 of the blower head 101 can be inserted into the insertion slot 425 more stably. The four electrical pins 151 of the insertion member 119 are electrically connected to the four conductive plates 51 on the circuit board 5 stably, and are not prone to poor contact.

[0063] It is understood that in other embodiments, magnetic adsorption can be achieved by providing a magnetic element only on one of the blower head 101 and the handle 102, while the housing of the other is made of metal.

[0064] The first body 41 is also provided with a display screen 412, which is electrically connected to the circuit board 5 and is used to display the remaining power of the battery 7 and the blowing speed of the blower head 101, such as speed 1, speed 2 and speed 3.

[0065] 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 circuit 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 drive motor 21; the higher the speed, the greater the rotation speed of the drive motor 21 and the stronger the airflow.

[0066] 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.

[0067] refer to Figure 1 and Figure 2 The bottom surface of the base 103 is flat, making it easy to place stably on a support surface such as a table or the ground.

[0068] The top of the base 103 has a positioning groove 8, which is used for detachable insertion with the handle 102. When the positioning groove 8 is inserted with the handle 102, the end of the handle 102 away from the base 103 is connected to the blower head 101. The blower head 101 can then be fixed on a support surface such as a table or the ground via the handle 102 and the base 103, allowing the user to use the blower head 101 to blow air and dissipate heat without having to hold the handle 102.

[0069] When the handle 102 is pulled out of the positioning slot 8, the user can insert the hair dryer head 101 into the handle 102, hold the handle 102, and use the hair dryer head 101 to blow air for heat dissipation. At this time, the handle 102 is equivalent to a handle, which the user can hold and use the hair dryer head 101 to blow air.

[0070] The base 103 also has a fixing groove 9, the length of which extends perpendicular to the thickness of the base 103. The side of the fixing groove 9 near the positioning groove 8 can be used for electronic devices such as mobile phones or tablets to lean against, and the side of the fixing groove 9 away from the positioning groove 8 has a limiting protrusion 91, which is used to limit the electronic device placed in the fixing groove 9 so as to make the electronic device stable and convenient for users to watch TV.

[0071] In one embodiment, a rubber anti-slip pad (not shown) can be glued to the base 103 in the fixing groove 9. The shape of the anti-slip pad is adapted to the fixing groove 9, so that the electronic device is not easy to slip when leaning against the anti-slip pad.

[0072] 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.

[0073] 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. Therefore, the protection scope of this utility model patent should be determined by the claims.
