[0032] Figure 1 This is a schematic diagram of the fan in an embodiment of this utility model. Figure 2 yes Figure 1 An exploded view of the components. (e.g.) Figure 1 , Figure 2 As shown, the easily assembled fan disclosed in this embodiment includes a front housing assembly 1, a rear housing assembly 2, and a fan assembly 3. The front housing assembly 1 and the rear housing assembly 2 form the overall outer shell of the fan, and the fan assembly 3 is fixed between the front housing assembly 1 and the rear housing assembly 2 to generate airflow.

[0033] The front shell assembly 1 is provided with multiple fixing posts 101, as shown in the figure, four fixing posts in this embodiment. The rear shell assembly 2 is provided with multiple first fixing channels 201, each corresponding to the position and number of the fixing posts 101. To see the first fixing channels 201, Figure 2 The rear mesh in the rear shell assembly 2 is hidden in the middle. The fan assembly 3 is provided with multiple second fixed channels 301, the number and position of which correspond to the fixed column 101.

[0034] The fan also includes multiple fasteners 4. In this embodiment, the fasteners 4 are screws, but other fasteners with the same function as screws, such as bolts or pins, can also be used. The multiple fasteners 4 pass through the first fixing channel 201 and the second fixing channel 301 in sequence and are then inserted into the fixing post 101 to fix the front shell assembly 1, the fan assembly 3, and the rear shell assembly 2 into one unit.

[0035] The front shell assembly 1, rear shell assembly 2, and fan assembly 3 are all assembled using a self-locking structural mechanism. This self-locking mechanism refers to the assembly of multiple structures together without relying on additional fasteners such as screws, bolts, or pins, but solely on inherent snap-fit, limiting, or hook structures within the structure itself.

[0036] This embodiment can complete the assembly and fixation of the entire fan with only 3 to 4 fasteners, thus improving the assembly efficiency of the product.

[0037] Figure 3 This is an exploded view of the front shell assembly in an embodiment of this utility model. Figure 4 yes Figure 3 An enlarged diagram of part A in the diagram. (See attached image.)

Multiple cylindrical insertion pieces 105 corresponding to the positions of the insertion holes 104 are provided on the edge of the front mesh 102. The insertion pieces 105 are inserted into the insertion holes 104 from the outer side of the front shell 103, securing the front mesh 102 onto the front shell 103. To make the assembly more secure, the insertion pieces 105 can be tilted away from the center of the front mesh 102 and have elasticity. After the insertion pieces 105 are inserted into the insertion holes 104, their restoring force will make them more firmly fixed in the insertion holes 104. Alternatively, other common methods can be used to fix them, such as bending the insertion pieces 105.

[0039] Figure 5 This is an exploded view of the fan assembly in an embodiment of this utility model. Figure 6 An exploded view of the fan assembly in another direction in an embodiment of this utility model. (See attached image.) Figure 5 , Figure 6 As shown, the fan assembly 3 includes a duct 302 and a fan 303. In this embodiment, the duct 302 and the fan 303 are fixed together by a snap-fit ​​structure. A first snap-fit ​​group 305 is provided on the first edge of the duct 302, and the edge of the fan 303 is embedded in the first snap-fit ​​group 305 to fix the fan 303 to the first edge of the duct 302.

[0040] The air duct 302 is provided with multiple first fixing holes 306, and the fan 303 is provided with multiple second fixing holes 307, the positions and numbers of which correspond to the first fixing holes 306. When the air duct 302 and the fan 303 are assembled together, the first fixing holes 306 and the second fixing holes 307 are positioned to form a second fixing channel 301. When the fixing member 4 passes through the fan assembly 3, it can simultaneously fix the air duct 302 and the fan 303 together between the front shell assembly 1 and the rear shell assembly 2.

[0041] Furthermore, in this embodiment, the fan is a warm air blower. The fan assembly 3 also includes a heating element 304. A second latching group 311 is provided on the second edge of the air duct 302. The heating element 304 is placed inside the air duct 302, and the edge of the heating element 304 is latched by the second latching group 311, fixing the heating element 304 inside the air duct 302. In this embodiment, along the air delivery direction of the fan, the two sides of the air duct 302 are the first side and the second side, respectively. Those skilled in the art will know that the fan can also be a cold air blower, as long as the heating element 304 is not installed, and even the air duct 302 can be omitted without affecting the basic blowing effect of the cold air blower.

[0042] Furthermore, a plurality of terminal channels 308 with one open end are provided on one side wall of the air duct 302 for the extension of the line terminals of the heating element 304. Furthermore, a clamping structure 309 is provided on the other side wall of the air duct 302. The fan assembly 3 also includes a temperature control component 310 for controlling the temperature of the heating element 304, and the temperature control component 310 is fixed to the other side wall of the air duct 302 by the clamping structure 309. Figure 6 As shown, the clamping structure 309 consists of multiple clamping components with one end fixed to the side wall of the air duct 302 and the other end having a certain gap from the side wall of the air duct 302 and having a certain elasticity. Multiple clamping components with different opening directions can be set to fix the temperature control component 310 at the same time to make the fixation more secure.

[0043] Furthermore, a hook 312 is provided on the first edge of the air duct 302, facing the rear housing assembly 2, so that the fan assembly 3 can be better positioned when it is fixed to the rear housing assembly 2.

[0044] Figure 7 This is an exploded view of the rear shell assembly in an embodiment of this utility model. Figure 8 An exploded view of the rear shell assembly from another direction in an embodiment of this utility model. Figure 9 This is a schematic diagram of the rear shell in an embodiment of this utility model. (See diagram below.) Figures 7-9As shown, the rear housing assembly 2 includes a rear housing 202 and a rear cover 203. The rear housing 202 and the rear cover 203 are fixed together by a snap-fit ​​structure. Specifically, a snap-fit ​​hole 204 is provided on the rear side edge of the rear housing 202, and a third snap-fit ​​group 211 is provided on the edge of the rear cover 203. The third snap-fit ​​group 211 is correspondingly engaged with the snap-fit ​​hole 204. A first fixing channel 201 is formed in the rear housing 202. When the rear cover 203 is fixed to the rear housing 202, it can cover the first fixing channel 201 to make the appearance of the fan more concise.

[0045] Furthermore, the rear cover assembly 2 also includes a button device 206, which is fixed to the edge of the rear cover 202 by a snap-fit ​​structure, and an installation position is provided on the rear cover 203 so that the button device 206 can be exposed after the rear cover 203 is installed.

[0046] Furthermore, a heat dissipation hole sidewall structure 207 is formed on the rear side of the rear shell 202, facing the interior of the rear shell 202. The heat dissipation hole sidewall structure 207 is integrally formed with the side of the rear shell 202. The outer side of the heat dissipation hole sidewall structure 207 surrounds the heat dissipation hole. The snap hole 204 and the first fixing channel 201 are both opened between the rear side of the rear shell 202 and the heat dissipation hole sidewall structure 207. The heat dissipation hole sidewall structure 207 plays a role in structural reinforcement.

[0047] Furthermore, inside the rear shell 202, an upper mounting groove 209 and a lower mounting groove 210 are fixed on the inner side of the heat dissipation hole sidewall structure 207. The two edges of the power board 208 are embedded between the upper mounting groove 209 and the lower mounting groove 210, so the power board 208 is also firmly fixed in the rear shell assembly 2.

[0048] Furthermore, when the fan assembly 3 is fixed, the upper and lower sets of hooks 312 are respectively hung on the upper and lower sides of the heat dissipation hole sidewall structure 207. When the fan assembly 3 is fixed to the rear shell assembly 2, the fan assembly 3 can be better positioned and its stability can be guaranteed.

[0049] Figure 10 yes Figure 1 A magnified view of section B. (See image below.) Figure 1 , Figure 10 As shown, the wind turbine also includes a support assembly 5, which is fixed to the rear housing assembly 2 via a self-locking structure. Specifically, the support assembly 5 is fixed to the rear housing assembly 2 by a rotating buckle. Combined with... Figure 7 , Figure 8 and Figure 10Both sides of the outer side wall of the rear shell 202 are provided with bracket mounting seats 205. The bracket mounting seats 205 include positioning shafts 2051 protruding from the outer side wall of the rear shell. Mounting holes are provided on the two integrally formed connecting arms of the bracket assembly 5. The two mounting holes are respectively fitted onto the two positioning shafts. The connecting arms of the bracket assembly 5 are clamped on the bracket mounting seats 205 so that the bracket assembly 5 and the rear shell assembly 2 are fixed together.

[0050] Furthermore, the bracket mounting base 205 also includes a wing 2052 extending from the outer wall of the positioning shaft 2051. The mounting hole provided on the connecting arm of the bracket assembly 5 includes a first arc portion 501 and a second arc portion 502 with a radius larger than the first arc portion 501. The first arc portion 501 is used to insert the positioning shaft 2051. The wing 2052 is placed inside the second arc portion 502 and can rotate at a preset angle within the range enclosed by the second arc portion 502. The smaller radius of the first arc portion 501 is used to limit the rotation range of the wing 2052, allowing the rear shell assembly 2 of the fan to rotate and adjust relative to the bracket assembly 5 at a certain angle, which can be used to adjust the air outlet angle.

[0051] Furthermore, the bracket assembly 5 also includes a decorative piece 503, which is fixed to the connecting arm of the bracket assembly 5 by a snap-fit ​​structure and covers the bracket mounting base 205, making the appearance of the fan more concise.

[0052] In this embodiment, the front shell assembly 1, the rear shell assembly 2, and the fan assembly 3 are all assembled using a structural self-locking mechanism, and the bracket assembly 5 and the rear shell assembly 2 are also assembled using a structural self-locking mechanism. This embodiment also provides a preferred implementation of the structural self-locking mechanism. Specifically, the front shell assembly 1 is mainly assembled using a plug-in structure, while the rear shell assembly 2 and the fan assembly 3 are mainly assembled using a snap-fit ​​structure. Several smaller structures are also assembled and fixed together using a structural self-locking mechanism. Those skilled in the art will understand that, in specific implementations, in addition to the specific fixing methods provided herein, other structural self-locking mechanisms can also be used to assemble the three components separately. For example, during the assembly of the front shell assembly 1, a snap-fit ​​structure can also be used to install the front mesh 102 and the front shell 103 together; these are not listed here.

[0053] 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.

[0054] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, 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 and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
