[0021] The beneficial effects of this utility model are:

[0022] This utility model provides a fan structure, including a blower assembly and a handheld assembly. The blower assembly includes a motor assembly and a first housing. The motor assembly is installed inside the first housing. The first housing has a first insertion hole along a first direction, and a first limiting block protrudes from the inner peripheral wall of the first insertion hole. The handheld assembly includes a mounting bracket and a support member. The mounting bracket has a first groove and is inserted into the first insertion hole. The first limiting block is inserted into the first groove, and both sides of the first groove in the first direction can abut against the first limiting block. The support member is inserted into the mounting bracket and is located on the bottom wall of the first groove, opposite to the first limiting block. The support member abuts against the mounting bracket in the depth direction of the first groove. The first direction intersects with the axial direction of the rotor.

[0023] For example, the blower assembly is used to generate airflow. The motor assembly includes a stator and a rotor. The stator is fixed relative to the first housing, and the rotor is inserted into the stator and can rotate relative to it. That is, when the stator receives current, it can generate a magnetic field, and the rotor can rotate relative to the stator around its own axis within the magnetic field. When the rotor rotates, airflow is formed. The first housing has an airflow channel and a first insertion hole. The axis of the airflow channel intersects the axis of the first insertion hole. The motor assembly is installed in the airflow channel, and the axis of the rotor is parallel to the axis of the airflow channel. When the rotor rotates, it can draw gas in from the air inlet end of the airflow channel and discharge it from the air outlet end of the airflow channel into the first housing, thereby forming airflow. The inner peripheral wall of the first insertion hole is provided with a first limiting block, which includes a first end face A and a first end face B disposed opposite to each other in a first direction.

[0024] The handheld component is easy for the user to grip. The mounting bracket is fixed to the first housing by a snap-fit. The mounting bracket has a first groove. The depth direction of the first groove intersects the axis of the first insertion hole. The first groove includes a bottom wall and two side walls opposite to each other in a first direction, referred to as the first bottom wall, the first side wall A, and the first side wall B, respectively. When the handheld component is assembled with the blower component, the mounting bracket is inserted into the first housing, and the first limiting block is inserted into the first groove. The first side wall A of the first groove can abut against the first end face A of the first limiting block in the first direction, and the first side wall B of the first groove can abut against the first end face B of the first limiting block in the first direction. In this way, the first groove limits the first limiting block in the first direction, thereby restricting the relative displacement of the handheld component and the blower component in the first direction.

[0025] Furthermore, the handheld assembly also includes a support member. The mounting bracket has a second insertion hole, and the support member is inserted into the second insertion hole. That is, the mounting bracket is sandwiched between the first limiting block and the support member. The outer wall of the support member can abut against the inner peripheral wall of the second insertion hole in the depth direction of the first groove, thereby restricting the movement of the mounting bracket relative to the first limiting block in the depth direction of the first groove, so that the first limiting block is always inserted in the first groove, maintaining the assembly relationship between the blower assembly and the handheld assembly. Moreover, no screws, nuts, or pins are used for fastening during the assembly process. Attached Figure Description

[0052] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0054] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0056] like Figures 1 to 14As shown, this utility model provides a fan structure, including a blower assembly 100 and a handheld assembly 200. The blower assembly 100 includes a motor assembly 110 and a first housing 130. The motor assembly 110 is installed inside the first housing 130. The first housing 130 has a first insertion hole 131 along a first direction X. A first limiting block 132 protrudes from the inner peripheral wall of the first insertion hole 131. The handheld assembly 200 includes a mounting bracket 210 and a support member 220. The mounting bracket 210 has a first groove 211. The mounting bracket 210 is inserted into the first insertion hole 131, the first limiting block 132 is inserted into the first groove 211, and the two opposite side walls of the first groove 211 in the first direction X can abut against the first limiting block 132. The support member 220 is inserted into the mounting bracket 210, and the support member 220 is located on the side of the bottom wall of the first groove 211 facing away from the first limiting block 132. The support member 220 can abut against the mounting bracket 210 in the depth direction of the first groove 211. The first direction X intersects with the axial direction Y of the rotor.

[0057] For example, the blower assembly 100 is used to generate airflow, and the motor assembly 110 includes a stator and a rotor. The stator is fixed relative to the first housing 130, and the rotor is inserted into the stator and can rotate relative to it. That is, when the stator receives current, the stator can generate a magnetic field, and the rotor can rotate relative to the stator around its own axis within the magnetic field. When the rotor rotates, airflow is formed. The first housing 130 has an airflow channel 133 and a first insertion hole 131. The axis of the airflow channel 133 intersects the axis of the first insertion hole 131. The motor assembly 110 is installed in the airflow channel 133. The axis of the rotor is parallel to the axis of the airflow channel 133. When the rotor rotates, it can draw gas in from the air inlet end 1332 of the airflow channel 133 and discharge it from the exhaust end 1331 of the airflow channel 133 into the first housing 130, thereby forming an airflow. The inner peripheral wall of the first insertion hole 131 is provided with a first limiting block 132. The first limiting block 132 includes a first end face A1321 and a first end face B1322 that are arranged opposite to each other in the first direction X.

[0058] Furthermore, the blower assembly 100 also includes fan blades mounted on the peripheral sidewall of the rotor.

[0059] The handheld component 200 is easy for the user to grip. The mounting bracket 210 is fixed to the first housing 130 by a snap-fit ​​connection. The mounting bracket 210 has a first groove 211, the depth direction of which intersects the axis of the first insertion hole 131. The first groove 211 includes a bottom wall and two side walls opposite to each other in the first direction X, which are respectively denoted as the first bottom wall 2113, the first side wall A2111, and the first side wall B2112. When the handheld component 200 is assembled with the blower component 100, the mounting bracket 210 is inserted into the first housing 130. The first limiting block 132 is inserted into the first groove 211. The first side wall A2111 of the first groove 211 can abut against the first end face A1321 of the first limiting block 132 in the first direction X. The first side wall B2112 of the first groove 211 can abut against the first end face B1322 of the first limiting block 132 in the first direction X. In this way, the first limiting block 132 is limited in the first direction X by the first groove 211, thereby limiting the relative displacement of the handheld component 200 and the blower component 100 in the first direction X.

[0060] Furthermore, the handheld assembly 200 also includes a support member 220. The mounting bracket 210 has a second insertion hole 213, and the support member 220 is inserted into the second insertion hole 213. That is, the mounting bracket 210 is sandwiched between the first limiting block 132 and the support member 220. The outer wall of the support member 220 can abut against the inner peripheral wall of the second insertion hole 213 in the depth direction of the first groove 211, thereby limiting the movement of the mounting bracket 210 relative to the first limiting block 132 in the depth direction of the first groove 211. This ensures that the first limiting block 132 is always inserted into the first groove 211, maintaining the assembly relationship between the blower assembly 100 and the handheld assembly 200. Moreover, no screws, nuts, or pins are used for fastening during the assembly process.

[0061] It should be noted that the depth direction of the first groove 211 intersects the axial direction of the first insertion hole 131.

[0062] Furthermore, a support platform 214 is provided in the second insertion hole 213 of the mounting bracket 210 to support the support member 220.

[0063] Furthermore, the support member 220 is capable of elastic deformation. During installation, the mounting bracket 210 is first inserted into the first insertion hole 131, so that the first limiting block 132 is inserted into the first groove 211. Then, the support member 220 is inserted into the second insertion hole 213. The support member 220 is squeezed by the inner peripheral wall of the second insertion hole 213 and undergoes elastic deformation. The support member 220 gives the mounting bracket 210 a reverse force, so that the mounting bracket 210 always has a tendency to expand outward, so that the first bottom wall 2113 always tends to move closer to the side where the first limiting block 132 is located, thereby maintaining the insertion relationship between the first limiting block 132 and the first groove 211.

[0064] Furthermore, the mounting bracket 210 and / or the first limiting block 132 can undergo elastic deformation. During the insertion process, when one or both of the elastically deformable components are squeezed, they deform. When the first limiting block 132 is aligned with the first groove 211, the first sidewall A2111 of the first limiting block 132 and / or the first groove 211 restores its deformation, so that when the mounting bracket 210 is inserted into the first insertion hole 131 along the axial direction of the first insertion hole 131, the first limiting block 132 can be inserted into the first groove 211 along the depth direction of the first groove 211.

[0065] Furthermore, the end of the mounting bracket 210 is provided with a first guide surface 216. When the mounting bracket 210 is inserted into the first insertion hole 131, the first guide surface 216 can facilitate the alignment of the mounting bracket 210 with the first insertion hole 131.

[0066] Furthermore, the first limiting block 132 is provided with a second guide surface 1323. When the mounting bracket 210 is inserted into the first insertion hole 131, the second guide surface 1323 can facilitate the alignment of the mounting bracket 210 and the first insertion hole 131.

[0067] Furthermore, the support member 220 is provided with a third guide surface 222. When the support member 220 is inserted into the second insertion hole 213, the third guide surface 222 can facilitate the alignment of the support member 220 with the second insertion hole 213.

[0068] In other embodiments, the inner sidewall of the first insertion hole 131 is provided with a first groove 211, and the mounting bracket 210 is provided with a first limiting block 132.

[0069] In other embodiments, the inner sidewall of the first insertion hole 131 is provided with a first groove A and a first limiting block B protruding therefrom. The first groove A and the first limiting block B are distributed along the axial direction of the first insertion hole 131. The outer sidewall of the mounting bracket 210 is provided with a first limiting block A and a first groove B protruding therefrom. The first limiting block A is inserted into the first groove A, and the first limiting block B is inserted into the first groove B.

[0070] Optionally, the blower assembly 100 also includes a second housing 140, in which the motor assembly 110 is installed, and the second housing 140 is inserted into and fixed relative to the first housing 130.

[0071] It should be noted that the axis of the second housing 140 coincides with the axis of the rotor of the motor assembly 110.

[0072] Optionally, the blower assembly 100 also includes a first end cap 150, a first baffle 142 formed in the second housing 140, the first end cap 150 and the second housing 140 being fixed relative to each other, and the motor assembly 110 being sandwiched between the first baffle 142 and the first end cap 150.

[0073] For example, during the assembly process of the motor assembly 110 and the second housing 140, the first flange 142 can abut against one side wall of the motor assembly 110 in the direction Y of the rotor axis. After the first end cover 150 is fixed relative to the second housing 140, the first end cover 150 can abut against the other end face of the motor assembly 110. The motor assembly 110 is sandwiched between the first flange 142 and the first end cover 150, maintaining the assembly relationship between the motor assembly 110 and the second housing 140.

[0074] Optionally, the second housing 140 is formed with a first limiting part 143, which is located on the side of the mounting bracket 210 opposite to the first limiting block 132. The first limiting part 143 can abut against the mounting bracket 210 in the depth direction of the first groove 211.

[0075] For example, when the mounting bracket 210 is inserted into the first insertion hole 131 of the first housing 130, the mounting bracket 210 and the first limiting part 143 of the second housing 140 are inserted into each other. The first limiting part 143 is inserted into the second insertion hole 213 and can abut against the inner sidewall of the second insertion hole 213 in the depth direction of the first groove 211, thereby maintaining the insertion relationship between the first limiting block 132 and the first groove 211.

[0076] Optionally, the second housing 140 is formed with a second limiting portion 144, which can abut against the support member 220 in the first direction X.

[0077] For example, when the mounting bracket 210 is inserted into the first insertion hole 131 of the first housing 130, the mounting bracket 210 and the second limiting part 144 of the second housing 140 are inserted into each other. The second limiting part 144 is inserted into the second insertion hole 213 and can abut against the axis of the support member 220 in the second insertion hole 213, that is, abut against it along the first direction X. This prevents the support member 220 from exiting from the second insertion hole 213, thereby maintaining the insertion relationship between the first limiting block 132 and the first groove 211.

[0078] Optionally, the blower assembly 100 may also include an air outlet 160, which is inserted into the first housing 130 and snap-fitted to the second housing 140.

[0079] For example, the air outlet 160 is located at the exhaust end of the blower assembly 100. A first locking hole 161 is provided on the peripheral side wall of the air outlet 160, and a first locking head 145 protrudes from the inner peripheral side of the second housing 140. During assembly, a portion of the air outlet 160 is inserted into the second housing 140, and the first locking head 145 is inserted into the first locking hole 161, thus securing the air outlet 160 to the second housing 140. This facilitates disassembly and eliminates the need for additional connecting parts.

[0080] Optionally, the handheld component 200 also includes a handle housing 230, a mounting bracket 210 inserted into the handle housing 230, the handle housing 230 having a second groove 231, the mounting bracket 210 having a second limiting block 212 protruding from it, the second limiting block 212 being inserted into the second groove 231, and the two opposite side walls of the second groove 231 in the first direction X being able to abut against the second limiting block 212.

[0081] The mounting bracket 210 has a second limiting block 212 protruding from it. The second limiting block 212 includes a second end face A2121 and a second end face B2122 disposed opposite to each other in the first direction X. The handle housing 230 has a third insertion hole 232. The mounting bracket 210 is inserted into the third insertion hole 232. The handle housing 230 is used to protect the mounting bracket 210. The mounting bracket 210 and the handle housing 230 are fixed by snap-fit. The inner sidewall of the third insertion hole 232 of the handle housing 230 has a second groove 231. The depth direction of the second groove 231 intersects the axis of the third insertion hole 232. The axis of the third insertion hole 232 is the first direction X. The second groove 231 includes a bottom wall and two side walls opposite to each other in the first direction X, which are respectively denoted as the second bottom wall 2311, the second side wall A2122, and the second side wall B2122. When the handle housing 230 is assembled with the mounting bracket 210, the second limiting block 212 is inserted into the second groove 231. The second side wall A2312 of the second groove 231 can abut against the second end face A2121 of the second limiting block 212 in the first direction X, and the second side wall B2313 of the second groove 231 can abut against the second end face B2122 of the second limiting block 212 in the first direction X. In this way, the second limiting block 212 is limited in the first direction X by the second groove 231, thereby limiting the relative displacement between the mounting bracket 210 and the handle housing 230 in the first direction X.

[0082] Optionally, the handheld component 200 also includes an electronic assembly 240, which includes a power supply unit 241 and a USB connector 242. The power supply unit 241 is electrically connected to the USB connector 242 and the motor assembly 110, respectively. A portion of the USB connector 242 is inserted into the handle housing 230, and the interface end of the USB connector 242 extends out of the handle housing 230.

[0083] In this way, the user can charge the power supply unit 241 via the USB connector 242, which is used to power the motor assembly 110.

[0084] For example, the power supply component 241 is connected to the motor assembly 110 via a wiring harness, and the support component 220 is fitted onto the wiring harness.

[0085] Optionally, the blower assembly 100 may also include a filter 170, which is installed at the air inlet 1332 of the blower assembly 100.

[0086] With this configuration, the filter 170 can intercept dust and impurities carried in the airflow at the air intake end 1332, preventing dust and impurities from adhering to the motor assembly 110.

[0087] Furthermore, the filter 170 is detachably connected to the second housing 140.

[0088] Optionally, the blower assembly 100 also includes a third housing 180, which is connected to the second housing 140 by a snap-fit, and a filter 170 is sandwiched between the third housing 180 and the second housing 140.

[0089] For example, the third housing 180 is provided with a second slot 181, and the second housing 140 is provided with a second slot head 146. During assembly, the second slot head 146 can be inserted into the second groove 231.
