[0065] In some embodiments, a dust cup mounting seat 140 is disposed on the body 100, and the dust cup mounting seat 140 is disposed at one end of the mounting groove 110. One end of the dust cup 200 is detachably connected to the dust cup mounting seat 140, and the other end of the dust cup 200 is abutted against the other opposite end of the mounting groove 110 to limit the position, thereby achieving fixed installation of the dust cup 200 in the mounting groove 110.

[0066] In some embodiments, a dust cup mounting seat 140 is provided at the upper end of the mounting groove 110. The upper end of the dust cup 200 is detachably connected to the dust cup mounting seat 140, and the lower end of the dust cup 200 is abutted against the bottom of the mounting groove 110 for limiting.

[0067] In some embodiments, a second air duct is provided in the dust cup mounting base 140. The air filtered in the dust cup 200 enters the fan through the second air duct and is then discharged.

[0068] In some embodiments, the dust collecting device further includes a locking assembly 300. The locking assembly 300 is configured to lock the dust cup 200 into the mounting groove 110. When the dust cup 200 needs to be removed, the locking assembly 300 is released from the dust cup 200, and then the dust cup 200 can be taken out of the mounting groove 110.

[0069] exist Figure 1 In the illustrated embodiment, the dust cup 200 is disposed in an oblique vertical position in the mounting groove 110 , the upper end of the dust cup 200 is detachably connected to the dust cup mounting seat 140 , and the lower end of the dust cup 200 is limitedly locked by a locking assembly 300 .

[0070] In some embodiments, the housing 100 includes an upper housing 120 and a lower housing 130 , wherein the upper housing 120 is connected to the lower housing 130 , and an installation space for installing components is formed therebetween. The installation slot 110 is formed on the upper side of the upper housing 120 .

[0071] The locking assembly 300 is disposed in the body 100, that is, the locking assembly 300 is disposed in the installation space. For example, the locking assembly 300 is disposed on the inner side of the upper shell 120, close to the installation groove 110, so as to cooperate with the dust cup 200. Figure 6 is a structural diagram of the upper shell 120 viewed from the upper side, Figure 7 It is a structural diagram of the upper shell 120 observed from the bottom. Figure 4 This is a structural diagram of a locking assembly 300 disposed in the upper shell 120, as viewed from the upper side. Figure 5 This is a structural diagram of a locking assembly 300 disposed in the upper shell 120, as viewed from the bottom.

[0072] Figure 83 is a structural diagram of the locking assembly 300. The locking assembly 300 includes a locking member 310 and a push member 320. Fig. 9 A structural diagram of the locking member 310 and the pressing member 320. Fig.10 is a structural diagram of a locking member 310, Fig.11 FIG. 3 is a structural diagram of the push member 320 .

[0073] The first end of the locking member 310 and the pressing member 320 are slidably matched with each other via an inclined surface. When the pressing member 320 is pressed by force, while the pressing member 320 moves, the pressing member 320 will drive the locking member 310 to move synchronously through the slidably matched inclined surfaces between the locking member 310 and the pressing member 320, and the movement direction of the pressing member 320 is different from the movement direction of the locking member 310. For example, when the pressing member 320 is pressed and moves in the horizontal direction, the locking member 310 will be driven to move in a direction perpendicular to the horizontal direction.

[0074] Combination Figure 3 and Figure 6 , a second opening 122 is provided on the inner wall of the installation slot 110. For example, the second opening 122 is provided on the bottom wall of the installation slot 110. A second limiting portion 313 is provided at the second end of the locking member 310. The second limiting portion 313 is configured to extend from or retract from the second opening 122.

[0075] Fig.13 1 is a structural diagram of the dust cup 200. A first limiting portion 210 is provided on the dust cup 200. When the second limiting portion 313 extends from the second opening 122, the second limiting portion 313 cooperates with the first limiting portion 210, thereby limiting the dust cup 200 to the mounting groove 110. When the second limiting portion 313 retracts from the second opening 122, the cooperation between the second limiting portion 313 and the first limiting portion 210 is released, and the dust cup 200 can be taken out of the mounting groove 110.

[0076] Reference Figure 2 and Figure 6 A first opening 121 is provided on the upper shell 120 of the body 100 , and the push member 320 extends from the first opening 121 , so that the user can perform a push operation.

[0077] When the dust cup 200 is installed in the installation groove 110 , the second limiting portion 313 extends from the second opening 122 , and the second limiting portion 313 is connected to the first limiting portion 210 , locking the dust cup 200 in the installation groove 110 .

[0078] When the dust cup 200 needs to be taken out, the pressing member 320 is pressed, and the locking member 310 is driven to move synchronously through the inclined sliding cooperation between the pressing member 320 and the locking member 310, so that the second matching part moves in a direction away from the first limiting part 210, thereby releasing the connection between the second limiting part 313 and the first limiting part 210, and then the dust cup 200 can be taken out.

[0079] Combination Figure 2 and Figure 8 Since the locking member 310 and the pressing member 320 are fitted with an inclined sliding surface, the movement direction of the locking member 310 can be different from the movement direction of the pressing member 320. The pressing member 320 is arranged on the side of the mounting groove 110, and the locking member 310 is arranged at the bottom of the mounting groove 110 to meet the setting requirements of the pressing member 320 and the locking member 310 at different positions of the casing.

[0080] In some embodiments, reference Fig.13 , the first limiting portion 210 is a groove. Figure 3 and Fig.10 The second limiting portion 313 is a protrusion. The first limiting portion 210 is connected to the second limiting portion 313, which means that the protrusion is embedded in the groove.

[0081] In some embodiments, the dust cup 200 is disposed in an oblique vertical position in the mounting groove 110. A dust cup mounting seat 140 is disposed at the upper end of the mounting groove 110, and a second opening 122 is disposed at the lower end of the mounting groove 110.

[0082] The upper end of the dust cup 200 is detachably connected to the dust cup mounting seat 140 , and the lower end of the dust cup 200 is provided with a first limiting portion 210 .

[0083] A fourth limiting portion 141 is provided on the circumferential wall of the dust cup mounting seat 140, and correspondingly, a fifth limiting portion (not shown) is provided on the upper end of the dust cup 200. The connection between the upper end of the dust cup 200 and the dust cup mounting seat 140 is achieved through the detachable connection between the fourth limiting portion 141 and the fifth limiting portion.

[0084] In some specific embodiments, the fourth limiting portion 141 is a slot, and the fifth limiting portion is a protrusion. The upper end of the dust cup 200 is connected to the dust cup mounting seat 140 by inserting the protrusion into the slot.

[0085] When installing the dust cup 200, firstly, the fourth limiting part 141 is matched with the fifth limiting part to realize the pre-positioning of the dust cup 200 in the mounting groove 110, and then the dust cup 200 is pushed into the mounting groove 110, the lower end of the dust cup 200 abuts against the bottom of the mounting groove 110, and the first limiting part 210 is engaged with the second limiting part 313, so that the lower end of the dust cup 200 is fixed. In this way, the upper end of the dust cup 200 is abutted against and limited by the dust cup mounting seat 140, and the lower end of the dust cup 200 is abutted against and limited by the bottom of the mounting groove 110, and is locked by the second limiting part 313, so that the dust cup 200 is fixedly installed in the mounting groove 110.

[0086] In some embodiments, reference Fig.10 The locking member 310 includes a first locking member section 311 and a second locking member section 312 of an integral structure. The locking member 310 is in an L-shaped structure. The upper end of the first locking member section 311 is slidably matched with the push member 320 through an inclined surface, and the second locking member section 312 extends from the bottom end of the first locking member section 311 to the side of the first locking member section 311. A second limiting portion 313 is provided on the free end of the second locking member section 312.

[0087] The locking member section 311 is located at the side of the installation slot 110. Since the push member 320 is disposed at the side of the installation slot 110, the locking member section 311 is disposed at the side of the installation slot 110 to facilitate the upper end of the locking member section 311 to cooperate with the push member 320.

[0088] The second section 312 of the locking member is located at the bottom of the mounting groove 110. Since the locking member 310 needs to lock and limit the bottom of the dust cup 200, the second section 312 of the locking member is set at the bottom of the mounting groove 110, so that the second limiting portion 313 on the second section 312 of the locking member cooperates with the first limiting portion 210 at the bottom of the dust cup 200.

[0089] The L-shaped structure of the locking member 310 enables the first end of the locking member 310 for cooperating with the pressing member 320 and the second end for locking with the dust cup 200 to be located on different sides of the installation groove 110.

[0090] In some embodiments, reference Fig.11 The push member 320 includes a push cap 321 and a mounting portion 322. The push cap 321 is disposed at one end of the mounting portion 322, and the push cap 321 is exposed from the first opening 121 for easy use in a push operation.

[0091] The pressing member 320 is installed on the housing through the mounting portion 322 to achieve a press-type installation of the pressing member 320. At the same time, the mounting portion 322 and the locking member section 311 are slidably matched through the inclined surface to press the pressing member 320 to achieve synchronous movement of the locking member 310.

[0092] In some embodiments, reference Fig.10 The first inclined surface 314 is disposed at the upper end of the first section 311 of the locking member. Fig.11 , a second inclined portion 323 is provided on the mounting portion 322. Fig. 9 The first inclined surface portion 314 and the second inclined surface portion 323 are slidably matched.

[0093] The pressing member 320 is pressed into the casing. Through the cooperation between the first inclined portion 314 and the second inclined portion 323, the pressing member 320 will drive the locking member 310 to move downward synchronously, so that the second limiting portion 313 is retracted from the second opening 122, thereby releasing the locking limit of the dust cup 200 by the locking member 310.

[0094] In some embodiments, stoppers 316 are respectively disposed on opposite sides of the first inclined portion 314 , and an inclined slide is formed between the two stoppers 316 . The second inclined portion 323 moves along the inclined slide to guide the movement.

[0095] In some embodiments, reference Fig.10 A first plane portion 315 is disposed at the upper end of the locking member section 311 , and a first inclined portion 314 extends obliquely downward from the first plane portion 315 .

[0096] Reference Fig.11 A second plane portion 324 is disposed on the mounting portion 322 , and a second inclined portion 323 extends obliquely downward from the second plane portion 324 .

[0097] Combination Fig. 9 The first plane portion 315 cooperates with the second plane portion 324. When the push member 320 is pressed, the second plane portion 324 moves along the first plane portion 315, supporting the horizontal movement of the push member 320. As the push member 320 moves horizontally, the second inclined portion 323 pushes the first inclined portion 314 downward, thereby driving the locking member 310 to move downward.

[0098] In some embodiments, reference Figure 8 The locking assembly 300 further includes a mounting seat 340. Figure 5 The mounting seat 340 is fixedly disposed on the inner wall of the body 100 , for example, the mounting seat 340 is fixedly disposed on the inner wall of the upper shell 120 .

[0099] The mounting seat 340 is a long strip structure, and a slide groove 341 is arranged in the mounting seat 340. The first section 311 of the locking member is located in the slide groove 341, and the first section 311 of the locking member can move along the length direction of the slide groove 341.

[0100] The two opposite side walls of the slide slot 341 are respectively provided with openings, which are opposite to the first opening 121 of the housing. The push member 320 is inserted into the openings, specifically, the mounting portion 322 is inserted into the two opposite openings, and the push cap 321 is exposed from the first opening 121 .

[0101] Specifically, a first opening 342 is provided on one side wall of the slide slot 341, and a second opening 343 is provided on the other opposite side wall of the slide slot 341. The first opening 342, the second opening 343 and the first opening 121 are directly opposite. The mounting portion 322 is sequentially inserted through the first opening 121, the first opening 342 and the second opening 343 to achieve a press-type installation of the push member 320.

[0102] The diameter of the first opening 342 is larger than that of the second opening 343. The diameter of the portion of the mounting portion 322 where the second inclined portion 323 is disposed is larger, and the first opening 342 is larger to facilitate insertion of the larger diameter portion of the mounting portion 322.

[0103] In some embodiments, reference Fig.12 The mounting seat 340 is provided with a first mounting ear 344 at the lower end thereof, and a second mounting ear 345 at the upper end thereof. Figure 7 , the first mounting column 124 and the second mounting column 125 are correspondingly arranged on the inner wall of the upper shell 120. Figure 5 , screws are driven between the first mounting ear 344 and the first mounting column 124 , and screws are driven between the second mounting ear 345 and the second mounting column 125 , so as to achieve fixed installation of the mounting seat 340 on the inner wall of the upper shell 120 .

[0104] In some embodiments, reference Fig.11 The push member 320 is provided with an extension portion 325, which extends from the push cap 321, and the extension direction of the extension portion 325 is the same as the extension direction of the mounting portion 322. The extension portion 325 is provided with a third limit portion 326. The third limit portion 326 is configured to cooperate with the circumferential outer wall of the opening to limit the movement range of the push member 320.

[0105] Specifically, the third limiting portion 326 is a hook structure, and the length of the extension portion 325 is less than the length of the mounting portion 322. The extension portion 325 extends into the slide groove 341 through the first opening 342. When the push member 320 is pressed, the extension portion 325 also moves along the first opening 342 synchronously. The third limiting portion 326 is engaged with the circumferential outer wall of the first opening 342 to prevent the mounting portion 322 from being separated from the mounting seat 340.

[0106] In some embodiments, reference Figure 8The locking assembly 300 further includes a first restoring member 330 . The first restoring member 330 is disposed in the slide slot 341 , and is configured to apply a force to the locking member 310 to move the second limiting portion 313 toward the direction close to the installation slot 110 .

[0107] Specifically, the first return member 330 is a compression spring, one end of which abuts against the lower end of the first section 311 of the locking member, and the other end of which abuts against the bottom wall of the slide slot 341. When the locking assembly 300 is in the locked state, the compression spring is in a contracted state, and the resilience of the compression spring pushes the locking member 310 upward, so that the second limiting portion 313 remains in a state of extending from the second opening 122, and further the second limiting portion 313 remains in a positional state of cooperating with the first limiting portion 210, thereby maintaining the locked state of the locking assembly 300.

[0108] When the pressing member 320 is pressed, the locking member 310 moves downward, pushing the compression spring to further contract, and the second limiting portion 313 retracts from the second opening 122. After the pressing member 320 is released, the resilience of the compression spring pushes the locking member 310 upward, so that the second limiting portion 313 re-extends into the second opening 122, and the locking assembly 300 is reset.

[0109] In some embodiments, reference Figure 3 An elastic portion 400 is disposed in the mounting groove 110, and the elastic portion 400 is configured to bounce the dust cup 200 in a direction away from the mounting groove 110 when the first limiting portion 210 is disengaged from the second limiting portion 313, so as to facilitate the removal of the dust cup 200.

[0110] In some embodiments, reference Figure 3 and Figure 6 The elastic part 400 includes a moving part 410 and a second resetting part 420. The bottom of the installation groove 110 is provided with a third opening 123, the moving part 410 is installed in the third opening 123, and the second resetting part 420 is provided between the bottom of the installation groove 110 and the moving part 410. The second resetting part 420 is a compression spring.

[0111] After the dust cup 200 is installed in the installation groove 110, the bottom of the dust cup 200 abuts against the moving part 410, and the moving part 410 is pressed downward by the pressure to press the second reset part 420, and the second reset part 420 is compressed. When the locking part 310 releases the locking effect on the lower end of the dust cup 200, the rebound force of the second reset part 420 bounces the dust cup 200 away from the installation groove 110, so that the dust cup 200 is easy to take out.

[0112] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0113] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
