DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described herein are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0033] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0036] like Figure 1-3 As shown, a cleaning device according to an embodiment includes: a separation mechanism 100, a filter element 200, a stop assembly 300, a housing 400, a handle 420, a hood 500, a post-filter 600, an exhaust fan 700, a dust cup 800, a filter screen 810, and a battery 820. When the exhaust fan 700 is working, the dirty air enters the cleaning device from the air inlet 801 of the dust cup 800, and then enters the separation mechanism 100 after being filtered by the filter screen 810 for air-dust separation. The separated air is filtered again by the filter element 200 and enters the exhaust fan 700, and then is filtered by the post-filter 600 and discharged.

[0037] like Figure 3-4 As shown, in one embodiment, the separation mechanism 100 is connected to the shell 400; the limiting component 300 is movably disposed on the shell 400 and is disposed opposite to the air outlet end of the separation mechanism 100, and the limiting component 300 can be close to or away from the air outlet end of the separation mechanism 100; the filter element 200 is detachably disposed between the air outlet end of the separation mechanism 100 and the limiting component 300.

[0038] When the limiting assembly 300 is in the first position (eg Figure 3 ), the filter element 200 abuts between the stop assembly 300 and the air outlet end of the separation mechanism 100. When the stop assembly 300 is in the second position (as shown in FIG. Figure 4 As shown), the limiting assembly 300 is separated from the filter element 200, and a disassembly opening 301 for the filter element 200 to pass through is formed between the limiting assembly 300 and the air outlet end of the separation mechanism 100.

[0039] In the above cleaning device, when the stop assembly 300 is in the first position, the filter 200 abuts between the stop assembly 300 and the air outlet end of the separation mechanism 100, and is used to filter the air coming out of the air outlet end of the separation mechanism 100 when the cleaning device is working. When the filter 200 needs to be removed, the stop assembly 300 can be moved to the second position away from the air outlet end of the separation mechanism 100 by moving the stop assembly 300, so that the stop assembly 300 is separated from the filter 200, so that the filter 200 is in a movable state, and then the filter 200 is removed from the cleaning device through the removal opening 301, which is simple and convenient to operate.

[0040] like Figure 5-6 As shown, in one embodiment, the limiting assembly 300 can be slidably disposed on the shell 400, and the limiting assembly 300 and the shell 400 are slidably matched, so that the limiting assembly 300 can slide close to or away from the air outlet end of the separation mechanism 100.

[0041] Specifically, the separation mechanism 100 is a cyclone separator, the shell 400 is arc-shaped, one side of the shell 400 is fixedly connected to the lower side of the shell end face 110 of the separation mechanism 100 by a snap or screw, and the limit assembly 300 is slidably connected to the upper side of the shell 400 and can slide close to or away from the separation mechanism 100.

[0042] In another embodiment, the limiting assembly 300 can be rollably disposed on the shell 400, and the limiting assembly 300 and the shell 400 are rollingly matched, so that the limiting assembly 300 can move closer to or away from the air outlet end of the separation mechanism 100 by rolling.

[0043] Specifically, the separation mechanism 100 is a cyclone separator, the shell 400 is arc-shaped, one side of the shell 400 is fixedly connected to the lower side of the shell end face 110 of the separation mechanism 100 by a snap or a screw, the limit assembly 300 is arranged on the upper side of the shell 400, and a ball or a roller is arranged between the limit assembly 300 and the shell 400. The limit assembly 300 can roll on the shell 400 through the ball or the roller to approach or move away from the separation mechanism 100.

[0044] like Figure 1 , Figure 3 As shown, in one embodiment, the hood 500 is fixedly arranged on the housing 400 and arranged opposite to the air outlet end of the separation mechanism 100, and the filter element 200 is detachably arranged between the air outlet end of the separation mechanism 100 and the hood 500. The hood 500 is used to install the exhaust fan 700. When the exhaust fan 700 is working, the outside air is sucked into the cleaning device through the air inlet 801 of the dust cup 800, and then enters the exhaust fan 700 after passing through the filter 810, the separation mechanism 100, and the filter element 200. By arranging the filter element 200 between the air outlet end of the separation mechanism 100 and the hood 500, the air coming out of the separation mechanism 100 can be filtered by the filter element 200 before entering the exhaust fan 700, which can reduce the amount of dirty substances mixed in the air entering the exhaust fan 700 and improve the service life of the exhaust fan 700.

[0045] Optionally, the exhaust fan 700 may be an exhaust pump or an exhaust motor, etc.; the filter element 200 includes a filter net and a bracket arranged around the circumference of the filter net. Of course, the filter element 200 may not include the bracket.

[0046] like Figure 3 As shown, further, the filter element 200 includes an air inlet side and an air outlet side opposite to the air inlet side, and the direction from the air inlet side to the air outlet side is consistent with the air outlet direction of the separation mechanism 100. In this way, the wind from the air outlet end of the separation mechanism 100 will reach the air inlet side of the filter element 200 along a straight line, so that the wind resistance of the air duct between the separation mechanism 100 and the filter element 200 is small.

[0047] Specifically, the filter element 200 is a filter screen, which is arranged opposite to the air outlet end of the separation mechanism 100 , and the connection direction between the air inlet side and the air outlet side of the filter screen is consistent with the air outlet direction of the separation mechanism 100 .

[0048] like Figure 5-7As shown, in one embodiment, the limiting assembly 300 cooperates with the housing 400 to form a receiving cavity when in the first position, the hood 500 is fixedly connected to the housing 400, and at least part of the hood 500 is located in the receiving cavity. After the limiting assembly 300 and the housing 400 form the receiving cavity, the limiting assembly 300 and the housing 400 can provide protection for the hood 500 to prevent the hood 500 from being disturbed by the external environment.

[0049] like Figure 6-7 As shown, further, the limiting assembly 300 includes a sleeve 320 movably arranged on the housing 400, and an abutment member 310 connected to the sleeve 320, the sleeve 320 is sleeved outside the hood 500, the abutment member 310 is arranged opposite to the air outlet end of the separation mechanism 100, the abutment member 310 abuts against the filter 200 when the limiting assembly 300 is in the first position, and the abutment member 310 is separated from the filter 200 when the limiting assembly 300 is in the second position. The sleeve 320 is sleeved outside the hood 500, and the sleeve 320 cooperates with the housing 400 to form a receiving cavity for protecting the hood 500; the abutment member 310 is connected to one end of the sleeve 320 close to the air outlet end of the separation mechanism 100, and by moving the sleeve 320, the position of the abutment member 310 can be changed, so that the abutment member 310 is close to or away from the filter 200.

[0050] Specifically, the sleeve 320 is rollingly or slidingly connected to the shell 400, and the sleeve 320 is sleeved outside the hood 500 and arranged opposite to the air outlet end of the separation mechanism 100. The abutment member 310 is fixedly arranged at one end of the sleeve 320 close to the separation mechanism 100. By moving the sleeve 320, the abutment member 310 can abut the filter element 200 or be separated from the filter element 200.

[0051] like Figure 6 As shown, more specifically, when the limiting assembly 300 is in the first position, the sleeve 320 fits against the end surface 110 of the shell 400 of the separation mechanism 100 so that there is no gap between the sleeve 320 and the separation mechanism 100, so as to prevent the wind from the separation mechanism 100 from leaking out; when the limiting assembly 300 is in the second position, the sleeve 320 is separated from the end surface 110 of the shell 400 of the separation mechanism 100, and a disassembly opening 301 is formed between the sleeve 320 and the end surface 110 of the shell 400 of the separation mechanism 100, so as to facilitate manual disassembly of the filter element 200 through the disassembly opening 301.

[0052] In addition, it should be noted that the exhaust fan 700 is disposed in the hood 500, and the exhaust fan 700 needs to be electrically connected to some components such as the battery 820 and the host. In the above embodiments, the filter element 200 is disassembled by moving the limit assembly 300, and the hood 500 is relatively stationary relative to the housing 400. Therefore, the exhaust fan 700 disposed in the hood 500 is also relatively stationary relative to the housing 400. In this way, it can be avoided that the reliability and life of the electrical connection terminal on the exhaust fan 700 are adversely affected during the process of multiple disassembly and assembly of the filter element 200.

[0053] like Figure 7-8 As shown, in one embodiment, a guide member 410 is provided on the housing 400, the guide member 410 is connected to the hood 500, and the hood 500 and the housing 400 are spaced apart, and a guide groove 321 is provided on the sleeve 320, and the sleeve 320 is sleeved outside the hood 500 and the guide member 410 passes through the guide groove 321, so that the guide groove 321 and the guide member 410 are guided and matched. The two ends of the guide member 410 are respectively connected to the hood 500 and the housing 400, so that the hood 500 and the housing 400 are spaced apart, and the guide groove 321 is provided on the sleeve 320, and the guide groove 321 can be passed through by the guide member 410, so that the sleeve 320 can be sleeved outside the hood 500. And because the guide member 410 passes through the guide groove 321, the guide member 410 can guide the movement of the sleeve 320, so that the sleeve 320 is more stable during the movement.

[0054] In one embodiment, the guide groove 321 has an opening at one end close to the separation mechanism 100, and the guide groove 321 is closed at one end away from the separation mechanism 100. The guide member 410 can be inserted into the guide groove 321 through the opening, and the guide member 410 is used to cooperate with the end of the guide groove 321 away from the separation mechanism 100.

[0055] The end of the guide groove 321 close to the separation mechanism 100 has an opening, so that the sleeve 320 and the abutment member 310 can be easily assembled. During the assembly process, the guide member 410 can be first passed through the opening of the guide groove 321, so that the sleeve 320 is sleeved outside the hood 500, and then the abutment member 310 is assembled on the end of the sleeve 320 close to the separation mechanism 100. The end of the guide groove 321 away from the separation mechanism 100 is closed, so that the sleeve 320 can be prevented from falling out of the hood 500.

[0056] Specifically, the abutment 310 is a sleeve end cover, the inner wall of the sleeve 320 is provided with a fixing column 322, and the sleeve end cover is also provided with a fixing column, and the two fixing columns are used for bolts to pass through, so that the abutment 310 and the sleeve 320 can be detachably fixed.

[0057] like Figure 8As shown, in one embodiment, a stopper 311 is provided on the abutting member 310, and the stopper 311 is matched with the guide member 410 when the stopper assembly 300 is in the second position. When the abutting member 310 moves to the stopper 311 and abuts against the guide member 410, it can be determined that the stopper assembly 300 has moved to the second position, and the filter element 200 can be disassembled at this position. In addition, when the stopper assembly 300 moves to the second position, the stopper assembly 300 cannot move further after the stopper 311 abuts against the guide member 410, so that the stopper assembly 300 can be prevented from moving excessively.

[0058] Specifically, the limiting portion 311 is a rib arranged on the abutment 310 and extending toward the sleeve 320. When the limiting assembly 300 moves to the second position in the direction away from the filter element 200, the rib abuts against one end of the guide member 410 close to the abutment 310. In this way, the guide member 410 can limit the abutment 310 from continuing to move in the direction away from the filter element 200, thereby limiting the entire limiting assembly 300 from continuing to move in the direction away from the filter element 200, and preventing the limiting assembly 300 from excessive movement.

[0059] like Figure 6 , Figure 8 As shown, in one embodiment, the cleaning device further includes a sealing member 900 , which is disposed on the limiting assembly 300 and seals the gap between the limiting assembly 300 and the hood 500 .

[0060] Specifically, the limiting assembly 300 is sleeved outside the hood 500, and the sealing member 900 is arranged on the inner side of the abutment member 310 and located between the hood 500 and the limiting assembly 300, so as to prevent the wind coming out of the separation mechanism 100 from passing through the gap between the hood 500 and the limiting assembly 300.

[0061] More specifically, the sealing member 900 is a sealing ring, which is disposed on the inner side of the abutting member 310 and abuts against the side wall of the hood 500 at one end close to the filter member 200 .

[0062] In one embodiment, the cleaning device further comprises a connecting member, the connecting member comprising a first connecting portion arranged on the separation mechanism 100, and a second connecting portion arranged on the limiting assembly 300, the second connecting portion being detachably fixedly connected to the first connecting portion when the limiting assembly 300 is in the first position. When the limiting assembly 300 is in the first position, the first connecting portion and the second connecting portion can be fixedly connected, so that the fixing of the limiting assembly 300 can be achieved, and even if the limiting assembly 300 is acted upon by an external force, it will not move in a direction away from the separation mechanism 100, so as to avoid the position of the filter element 200 moving after losing the force of the limiting assembly 300, thereby affecting the use. When the filter element 200 needs to be disassembled, the first connecting portion and the second connecting portion can be separated, so that the limiting assembly 300 can move relative to the separation mechanism 100.

[0063] Optionally, the first connecting part is a magnet fixed on the separation mechanism 100, and the second fixing part is a magnet fixed on the limiting assembly 300, and the two magnets are magnetically matched; or the first connecting part is a buckle fixed on the separation mechanism 100, and the second fixing part is a slot fixed on the limiting mechanism, and the buckle can be snapped into the slot; or the first connecting part is a threaded hole set on the separation mechanism 100, and the second connecting part is a threaded hole set on the limiting assembly 300, and bolts can be passed through the two threaded holes.

[0064] like Figure 1 As shown, in one embodiment, the post filter 600 is fixed to the sleeve 320 by a screw buckle, and is used to filter the air coming out of the exhaust fan 700. Of course, in other embodiments, the post filter 600 can also be fixed to the housing 400, as long as it does not affect the movement of the limiting assembly 300.

[0065] An embodiment further relates to a vacuum cleaner, comprising the cleaning tool as described above.

[0066] The vacuum cleaner is provided with the cleaning device. In the cleaning device, when the stop assembly 300 is in the first position, the filter 200 abuts between the stop assembly 300 and the air outlet of the separation mechanism 100, and is used to filter the air coming out of the air outlet of the separation mechanism 100 when the cleaning device is working. When the filter 200 needs to be removed, the stop assembly 300 can be moved to the second position away from the air outlet of the separation mechanism 100 by moving the stop assembly 300, so that the stop assembly 300 is separated from the filter 200, so that the filter 200 is in a movable state, and then the filter 200 is removed from the cleaning device through the removal opening 301, which is simple and convenient to operate.

[0067] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0068] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. 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 present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
