[0046] The following is a further non-restrictive detailed description of the utility model technical solution in conjunction with the preferred embodiment and its accompanying drawings. In the description of the utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings. In addition, the terms "first" and "second" are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the utility model, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the utility model, and cannot be understood as limitations on the utility model.

[0047] like Figure 1-Figure 4 As shown, a dust collecting assembly of one embodiment of the utility model includes a body 1, a dust cup 2, a filter assembly 3 and at least one automatic locking assembly 4, the dust cup 2 is arranged on the body 1, and the bottom of the dust cup 2 can be opened to achieve dust cleaning, and the filter assembly 3 is exposed, the filter assembly 3 is arranged in the dust cup 2, and the dust cup 2 has an opening 25 for dumping garbage, and the user can take out the filter assembly 3 from the opening 25 along the axial direction of the dust cup 2.

[0048] The body 1 includes a motor 6, which is used to provide suction force. The suction force drives the mixed gas on the surface to be cleaned to enter the dust cup 2 through the air inlet 10. The filter component 3 is used to separate solid dust and clean air. The filter component 3 is usually a cyclone separation, or has an air vent structure so it is often blocked by dust, so it needs to be taken down and cleaned frequently. A dust holding chamber (not shown in the figure) is set at the bottom of the dust cup 2. The user can empty the dust inside the dust holding chamber by opening the bottom cover 21 and other operations.

[0049] like Fig.10 As shown, a guide structure 100 is provided at the air inlet 10, and the guide structure 100 allows the mixed gas to enter the dust cup 2 along its tangent.

[0050] The dust collecting assembly also includes a latch assembly, and the filter assembly 3 is detachably connected to the dust cup 2 through the latch assembly. Specifically, the latch assembly includes at least one automatic locking assembly 4 and a manual locking assembly 5, wherein the latch assembly can be two automatic locking assemblies 4, or one automatic locking assembly 4 and one manual locking assembly 5.

[0051] In one embodiment of the present invention, the latch assembly includes a pair of automatic lock components 4 symmetrically arranged on both sides of the dust cup 2, such as Figure 4 As shown, the automatic locking assembly 4 includes a snap-fit ​​block 42, which can move between a locked position and an unlocked position; when removing the filter assembly 3, the user directly drags the filter assembly 3 along the axial direction of the dust cup 2, and the filter assembly 3 can drive the snap-fit ​​block 42 to move from the locked position to the unlocked position. At this time, the filter assembly 3 is disengaged from the snap-fit ​​block 42.

[0052] The automatic locking assembly 4 also includes a fixed block 40 and a first elastic member 41. The fixed block 40 is fixed to the outside of the dust cup 2. One end of the first elastic member 41 abuts against the fixed block 40, and the other end abuts against one end of the clamping block 42. The other end of the clamping block 42 passes through the dust cup 2 and can be matched with the groove 300 on the filter assembly 3.

[0053] The other end of the clamping block 42 is provided with a first inclined surface 43 and a second inclined surface 44, and a push block 301 is provided on the filter assembly 3. When the filter assembly 3 is disassembled, the push block 301 is slidably connected to the first inclined surface 43 of the clamping block 42; when the filter assembly 3 is assembled, the push block 301 is slidably connected to the second inclined surface 44 of the clamping block 42.

[0054] like Fig. 9 As shown, the filter assembly 3 has a circularly symmetrical structure, and the groove 300 is circumferentially arranged on the outside of the filter assembly 3, so that the filter assembly 3 can be installed in any direction without affecting the use of the machine.

[0055] The filter assembly 3 includes a cyclone acceleration section 34 and a primary filter 35. The cyclone acceleration section 34 corresponds to the air inlet 10 in the height direction to prevent the mixed gas entering from the air inlet 100 from directly entering the dust cup 2 through the mesh holes (not shown) of the primary filter 35. The cyclone acceleration section 34 has no air holes, so the mixed gas will rotate along its surface. If there is no cyclone acceleration section 34, the particles in the mixed gas entering from the air inlet 10 will directly block the mesh holes of the primary filter 35 corresponding to its opening.

[0056] like Figure 5-Figure 6 As shown, in another embodiment of the utility model, the latch assembly includes an automatic lock assembly 4 and a manual lock assembly 5. The manual lock assembly 5 is arranged on the dust cup 2 and can be matched with the filter assembly 3. When removing the filter assembly 3, the user needs to manually press the manual lock assembly 5 to make the manual lock assembly 5 disengage from the filter assembly 3. At this time, the user can directly drag the filter assembly 3 along the axial direction of the dust cup 2, and the filter assembly 3 can drive the clamping block 42 to move from the locked position to the unlocked position. At this time, the filter assembly 3 is disengaged from the clamping block 42, and then the filter assembly 3 can be taken out from the dust cup 2, which is very convenient. The filter assembly 3 moves along the axis toward the bottom cover 21 of the dust cup 2 without rotation.

[0057] The manual locking assembly 5 includes a button 50 and a second elastic member 51. The button 50 is rotatably fixedly connected to the dust cup 2 via a rotating shaft 52. One end of the second elastic member 51 abuts against one end of the button 50 and the other end abuts against the dust cup 2. The other end of the button 50 can be matched with the filter assembly 3.

[0058] The button 50 includes a pressing portion 500 and a buckle portion 501 , which are located on both sides of the rotating shaft 52 , one end of the second elastic member 51 abuts against the pressing portion 500 , and the buckle portion 501 is matched with the fastener 302 on the filter assembly 3 .

[0059] The buckle portion 501 is provided with a first wedge surface 502, and the fastener 302 is provided with a second wedge surface 303. When the filter assembly 3 is assembled, the second wedge surface 303 of the fastener 302 is slidably connected with the first wedge surface 502 of the buckle portion 501. The entire installation process does not require pressing the button 50, and the installation is convenient and quick.

[0060] like Figure 2 As shown, a sealing ring 36 is sleeved on the outer side of the filter assembly 3. The sealing ring 36 is made of soft rubber material. The sealing ring 36 abuts against the inner wall of the dust cup 2 to achieve sealing inside the cyclone chamber.

[0061] The maximum outer contour of the filter assembly 3 is smaller than the minimum inner diameter of the dust cup 2, ensuring that the filter assembly 3 will not be interfered with by the dust cup 2 when it is disassembled from top to bottom. Specifically, the maximum outer contour of the filter assembly 3 is the outer contour of the sealing ring 36. Because the sealing ring 36 is elastic, it can be barely installed even if there is an interference fit with the inner wall of the dust cup 2. However, in order to ensure the user's feel, the inner diameter of the dust cup gradually increases from top to bottom, or remains consistent.

[0062] A trigger is provided on the top of the filter assembly 3 to trigger the power-on switch of the dust collection assembly. The trigger can be a protruding structure. When the filter assembly 3 is installed, the protruding structure directly presses the power-on switch to put the whole machine in a startable state. This prevents the motor 6 on the dust collection assembly from being mistakenly started when the filter assembly 3 is forgotten to be installed, so that dust directly enters the motor 6 and causes irreversible damage to the motor 6.

[0063] In one embodiment of the utility model, the dust cup 2 includes a cup body 20 and a bottom cover 21. One side of the bottom cover 21 is hinged to the cup body 20 and the other side is buckled with the cup body 20. The filter assembly 3 is accommodated in the cup body 20. When the bottom cover 21 is buckled with the cup body 20, the bottom cover 21 abuts against the filter assembly 3 to prevent the filter assembly 3 from falling off the dust cup 2 due to vibration caused during operation. When the dust collecting component with a manual locking assembly 5 needs to replace the HEPA 31, first open the bottom cover 21, clean the dirt in the dust cup 2, then manually press the manual locking assembly 5 with one hand, and directly drag the filter assembly 3 along the axial direction of the dust cup 2 with the other hand to remove the filter assembly 3 and replace the HEPA 31 on the filter assembly 3, and clean the primary filter 35 at the same time; when the dust collecting component without a manual locking assembly 5 needs to replace the HEPA 31, first open the bottom cover 21, clean the dirt in the dust cup 2, and then directly drag the filter assembly 3 along the axial direction of the dust cup 2 to remove the filter assembly 3, and then replace the HEPA 31 on the filter assembly 3, and clean the primary filter 35 at the same time. Compared with the solution with a manual locking assembly 5, the technical solution without a manual locking assembly 5 is more convenient to operate.

[0064] like Figure 7 As shown, in another embodiment of the utility model, the dust cup 2 includes an upper cup body 22 and a lower cup body 23 that are detachably connected. Specifically, a matching groove 230 is provided on the lower cup body 23, and a matching block 220 is provided on the upper cup body 22. During installation, the matching block 220 of the upper cup body 22 enters the matching groove 230 from the opening 231 of the matching groove 230, and then the lower cup body 23 is rotated so that the matching block 220 of the upper cup body 22 is received in the matching portion 232 of the matching groove 230 to complete the assembly. Of course, the matching groove 230 can also be set on the upper cup body 22, and the matching block 220 can be set on the lower cup body 23, or the upper cup body 22 and the lower cup body 23 can be assembled in the form of a buckle.

[0065] The filter assembly 3 is at least partially contained in the lower cup body 23. This design can bring two advantages. First, after the cup body 23 is removed, the dust in the dust cup 2 will fall into the lower cup body 23, preventing the dust in the dust cup 2 from falling directly to the ground. Second, after the cup body 23 is removed, part of the filter assembly 3 will be exposed to the outside, making it more convenient for users to directly drag the filter assembly 3, and the operation is more convenient. The upper cup body 22 can be small at the top and large at the bottom, and the lower cup body 23 can be set normally or large at the top and small at the bottom.

[0066] like Figure 8 As shown, the joint 24 of the upper cup body 22 and the lower cup body 23 is located below the air inlet 10 of the body 1, so that the air inlet sealing is guaranteed. Because the lower cup body 23 is connected to the whole machine in a detachable manner, if the air inlet 10 is docked with the lower cup body 23, it will cause difficulty in sealing the air inlet 10.

[0067] The distance L between the joint 24 of the upper cup body 22 and the lower cup body 23 and the air inlet 10 of the body 1 is 5-40 mm, which is convenient for the user to clean the air inlet 10 when the air inlet 10 is blocked by garbage.

[0068] The filter assembly 3 includes a cyclone cone 30 and a hepa 31 disposed in the dust cup 2. The hepa 31 is located downstream of the cyclone cone 30. The cyclone cone 30 and the hepa 31 are integrated into an integral structure, and the cyclone cone 30 is detachably connected to the dust cup 2 through an automatic locking assembly 4; the bottom of the dust cup 2 can be opened to expose the cyclone cone 30 of the filter assembly 3. When the hepa 31 needs to be replaced, there is no need to disassemble the dust cup 2. The user manually grabs the cyclone cone 30 and can drag out the cyclone cone 30 and the hepa 31 on the cyclone cone 30 together. In this embodiment, the above-mentioned groove 300, push block 301 and fastener 302 are all disposed on the cyclone cone 30.

[0069] In this embodiment, the HEPA 31 and the cyclone cone 30 are detachably connected, and a receiving cavity 305 is provided on the cyclone cone 30 , and the HEPA 31 is accommodated in the receiving cavity 305 .

[0070] A slot 304 is formed on the inner wall of the receiving cavity 305 , and a block 310 matched with the slot 304 is provided on the HEP 31 .

[0071] The filter assembly 3 further includes a sponge 32 , which is disposed in the receiving chamber 305 and between the cyclone cone 30 and the HEPA 31 .

[0072] The filter assembly 3 also includes a flange 33, which is sleeved on the outside of the cyclone cone 30, and the joint 24 of the upper cup body 22 and the lower cup body 23 is located above or below the flange 33. When the joint 24 of the upper cup body 22 and the lower cup body 23 is located above the flange 33, the user can clean the primary ash storage chamber of the cyclone cone 30 and some large particles clamped above the flange when removing the lower cup body 23. When the joint 24 of the upper cup body 22 and the lower cup body 23 is located below the flange 33, the advantage of this arrangement is that during the process of removing the lower cup body 23, the garbage accumulated above the flange 33 will not suddenly fall and dirty the user's hands.

[0073] A cleaning device comprises the above-mentioned dust collecting component.

[0074] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
