[0002] As a commonly used cleaning equipment, vacuum cleaners can automatically and quickly clean dust, greatly reducing the labor intensity of cleaning work and enhancing the cleaning effect. Vacuum cleaners generally include a dust cup assembly and an air suction channel. Negative pressure is formed in the air suction channel to suck air into the dust cup assembly, and the dust and other solid particles are stored in the dust cup through the separation action of the cyclone separator. In order to prevent large dust particles from entering the cyclone separator, a cyclone cover is set on the outside of the cyclone separator to block large dust particles, causing dust to adhere to the cyclone cover, affecting the dust collection effect.

[0062] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0063] 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.

[0064] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field 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.

[0065] The dust cup assembly serves as a container for storing dust in a cleaning device, and often includes a dust cup 100 and a cyclone separator 201. The air entering the dust cup 100 is separated by the cyclone separator 201, leaving the dust in the dust cup 100. The separated air enters the cyclone separator 201 and is then blown into the atmosphere from the cyclone separator 201. During this process, dust is more likely to adhere to the surface of the cyclone separator 201, affecting the air entry. Generally, users will clean the dust on the surface of the cyclone separator 201 separately when dumping the dust, but this undoubtedly wastes the user's time and affects the user's satisfaction.

[0066] In order to solve the above problems, Figure 1-5 and Figure 9-11 As shown, this embodiment provides a dust cup assembly, including: a dust cup 100, including a first end 101 and a second end 102 arranged opposite to each other, the first end 101 is provided with a dust cup cover 103 that can be opened or closed, and the dust cup cover 103 is provided with a locking protrusion 1031; the dust cup 100 is a hollow structure with a side wall, the first end 101 of the dust cup 100 is provided with a first through hole 1011, the first through hole 1011 is opened or closed by the dust cup cover 103, and the second end 102 is provided with a second through hole, and the second through hole is not covered. The cyclone separation unit 200 is arranged in the dust cup 100 and close to the second end 102, and is used to separate the dirty air in the dust cup 100; after the dirty air enters the dust cup 100, the cyclone separation unit 200 separates the dirty air and collects the dust between the dust cup 100 and the cyclone separation unit 200. The separated air passes through the cyclone separation unit 200 and is sucked into the air inlet of the vacuum motor 11, and then discharged into the air.

[0067] The ash scraping and dumping linkage part 300 includes a driving member 301, a connecting rod 302, an ash scraping member 303 and a knob member 304. The driving member 301 is connected to the ash scraping member 303 through the connecting rod 302. The ash scraping member 303 is arranged on the outer periphery of the cyclone separation part 200. The knob member 304 is close to the first end 101. The knob member 304 includes a rotating part 3041 and a first rotating arm 3042 connected to the rotating part 3041 and a locking member 3043. The locking member 3043 can be locked with the locking member 3043. The protrusion 1031 is locked; wherein the driving member 301 drives the connecting rod 302 to move toward the knob member 304, so that the connecting rod 302 approaches and presses the first rotating arm 3042, pushing the knob member 304 to rotate around the rotating axis of the rotating part 3041, and then drives the locking member 3043 to rotate away from the locking protrusion 1031, thereby opening the dust cup cover 103; at the same time, the scraping member 303 can scrape the dust on the outer peripheral surface of the cyclone separation part 200 under the drive of the connecting rod 302. In this embodiment, because the connecting rod 302 and the dust scraping member 303 are connected, when the driving member 301 drives the connecting rod 302 to move close to the knob member 304, it can also drive the dust scraping member 303 to move along the outer periphery of the cyclone separation part 200 to scrape off the dust on the surface of the cyclone separation part 200. At the same time, when the driving member 301 drives the connecting rod 302 to move close to the knob member 304, the connecting rod 302 gradually approaches the knob member 304 until it contacts the first rotating arm 3042 of the knob member 304. The connecting rod 302 will continue to move toward the first rotating arm 3042 under the driving action of the driving member 301. 042 applies pressure, thereby pushing the first rotating arm 3042 to rotate, and then pushing the locking member 3043 to rotate, so that the locking member 3043 gradually moves away from the locking protrusion 1031 to achieve unlocking, so that the dust cup cover 103 can be opened. In one implementation of this embodiment, the opening and closing of the dust cup cover 103 is achieved by unlocking and locking the locking member 3043 and the locking protrusion 1031. When the dust cup cover 103 needs to be closed after the dust is poured, just press the dust cup cover 103 in the direction close to the first end 101 until the locking member 3043 is locked with the locking protrusion 1031. Figure 6 and 10 As shown, in a possible implementation of this embodiment, a first torsion spring is provided at the pivot axis of the dust cup cover 103, so that the dust cup cover 103 has a prefabricated force to return to the closed position. When the user releases the driving member 301, the dust cup cover 103 returns to the closed state due to the action of the first torsion spring, and when the user releases the driving member 301, the locking member 3043 returns to the locked state with 1031 due to the action of the second torsion spring 3045. Fig.12As shown, in a possible implementation, a groove hole can be set on the locking protrusion 1031, and a protrusion 30431 that can be snapped with the groove hole can be set on the locking piece 3043. When the locking piece 3043 and the locking protrusion 1031 are unlocked, the protrusion 30431 is away from the groove hole. When the locking piece 3043 and the locking protrusion 1031 are locked, the protrusion 30431 is inserted into the groove hole.

[0068] In one possible implementation, Figure 2 , 4 -As shown in Figures 7 and 12, a trigger member 305 is further provided on the first end 101 of the dust cup 100, and the knob member 304 also includes a second rotating arm 3044, and the locking protrusion 1031 extends toward the interior of the dust cup 100; by pressing the trigger member 305 so that the trigger member 305 contacts and pushes the second rotating arm 3044 to rotate, the rotating part 3041 is driven to rotate and the locking member 3043 is driven to rotate away from the locking protrusion 1031. In this embodiment, two ways of opening the dust cup cover 103 are provided. One is to drive the connecting rod 302 to move close to the knob member 304 through the driving member 301 until the connecting rod 302 contacts the first rotating arm 3042, and continues to apply pressure to the first rotating arm 3042, driving the locking member 3043 to move away from the locking protrusion 1031, so that the locking member 3043 and the locking protrusion 1031 are unlocked, thereby opening the dust cup cover 103; the other is to press the trigger member 305 so that the trigger member 305 contacts the second rotating arm 3044 of the knob member, and continues to apply pressure to the second rotating arm 3044 to push the second rotating arm 3044 to rotate, thereby driving the locking member 3043 to move in a direction away from the locking protrusion 1031. The first way of opening the dust cup cover 103 is more suitable for the user to pour out the dust after vacuuming, while the second way of opening the dust cup cover 103 is more suitable for the user to place the entire cleaning device or the handheld part on the vacuum base after vacuuming, and trigger the trigger part 305 through the trigger part on the vacuum base. A recovery tank and a vacuum motor can be provided on the vacuum cleaner base, and the vacuum motor collects the dust in the dust cup 100 into the recovery tank.

[0069] In one possible implementation, Fig.12As shown, the first rotating arm 3042 and the second rotating arm 3044 are distributed on both sides of the locking member 3043 . Taking the example of the user facing the knob member 304, the first rotating arm 3042 is located at the user's right hand, and the second rotating arm 3044 is located at the user's left hand, when the first method of opening the dust cup cover 103 is adopted, the driving member 301 drives the connecting rod 302 to move close to the knob member 304, and the connecting rod 302 contacts and pushes the first rotating arm 3042 to move clockwise, and at the same time, the rotating part 3041 and the second rotating arm 3044 also rotate clockwise, and the locking member 3043 also rotates clockwise and gradually moves away from the locking protrusion 1031; when the second method of opening the dust cup cover 103 is adopted, the trigger member 305 is pressed, so that the trigger member 305 moves toward the inside of the dust cup 100 until the trigger member 305 contacts the second rotating arm 3044 and pushes the second rotating arm 3044 to rotate clockwise, and at the same time, the rotating part 3041 and the first rotating arm 3042 also rotate clockwise, and the locking member 3043 also rotates clockwise and gradually moves away from the locking protrusion 1031. The first rotating arm 3042 and the second rotating arm 3044 are respectively arranged on both sides of the locking member 3043, which provides sufficient space for the operation of the driving member 301 and the triggering member 305 and also ensures the balance of the rotation.

[0070] In one possible implementation, Figure 4-6 As shown, the dust cup assembly is further provided with an elastic rod 306, the connecting rod 302 includes a pressing portion 3021 and a connecting portion 3022 connected to the pressing portion 3021, and the elastic rod 306 is inserted into the connecting portion 3022; the driving member 301 drives the connecting portion 3022 to move on the elastic rod 306, so as to drive the pressing portion 3021 to approach and press the first rotating arm 3042. Figure 6 As shown, in a possible implementation, the elastic rod 306 includes a connecting rod 3061 and an elastic member 3062 sleeved on the connecting rod 3061. When the driving member 301 drives the connecting part 3022 to move on the elastic rod 306, the connecting part 3022 will press the elastic member 3062 to cause it to produce elastic deformation until the pressing part 3021 pushes the first rotating arm 3042 to reach a certain position, that is, the locking member 3043 and the locking protrusion 1031 are unlocked, and the driving member 301 is released. Then, the connecting part 3022 will be restored to the state when it is not driven by the driving member 301 under the elastic action of the elastic member 3062, that is, the elastic member 3062 restores to its natural state.

[0071] In one possible implementation, Figure 7 , 8As shown in Figure 13, a first protrusion 104 extending into the dust cup 100 is provided on the first end 101, and the first protrusion 104 includes a first opening 1041 opened on the first end 101 and a second opening 1042 opposite to the first opening 1041. A first notch 1043 is provided on the side wall of the first protrusion 104, and the first opening 1041, the second opening 1042, and the first notch 1043 are connected; the trigger member 305 includes a pressing end 3051 and a trigger end 3052 arranged opposite to each other, and the side wall of the trigger member 305 is also provided with a flange protrusion 3053; in a possible implementation, the first protrusion 1 04 and the first end 101 are integrally formed, and the function of the first protrusion 104 is to limit the movement relationship between the trigger member 305 when it is not triggered and when it is triggered. The trigger member 305 is embedded in the first protrusion 104, the pressing end 3051 is arranged in the first opening 1041, the trigger end 3052 is arranged in the second opening 1042, and the flange protrusion 3053 is arranged in the first notch 1043. When the pressing end 3051 is pressed, the flange protrusion 3053 can move in the first notch 1043 along the force direction, and the trigger end 3052 can push the second rotating arm 3044 to rotate under the action of pressure. When the pressing end 3051 is subjected to pressure, the entire trigger member 305 will move toward the direction close to the dust cup 100. Since the first notch 1043 limits the movement of the flange protrusion 3053, the trigger member 305 can only move within a certain range. Taking the trigger end 3052 as an example, the movement range of the trigger member 305 is described, that is, between the state where the trigger end 3052 is not subjected to force and is stationary to the state where the trigger end 3052 presses the second rotating arm 3044 to unlock the locking member 3043 and the locking protrusion 1031.

[0072] In one possible implementation, Figure 1-3 As shown, an air inlet 105 is provided on the side wall of the dust cup 100, and the cyclone separation part 200 includes a cyclone separator 201 and a cyclone cover 202 mounted on the outer periphery of the cyclone separator 201, a first ash storage chamber 203 is formed between the cyclone cover 202 and the dust cup 100, and a second ash storage chamber 204 is formed between the cyclone cover 202 and the cyclone separator 201. When the dirty air enters the dust cup 100 from the air inlet 105, the cyclone separation unit 200 first performs the first step of cyclone separation on the dirty air, and gathers larger dust in the first dust storage chamber 203. The smaller dust and airflow pass through the cyclone cover 202 and enter the cyclone separator 201. The smaller dust and airflow are then subjected to the second step of cyclone separation, and the smaller dust is gathered in the second ash storage chamber 204. After two steps of cyclone separation, the dirty air originally inhaled almost no longer carries dust, and the air no longer carrying dust is discharged from the second end 102 of the dust cup 100 through the cyclone separator 201.

[0073] In one possible implementation, Figure 16-19As shown, the cyclone separator 201 includes a first connecting member 2012, a second connecting member 2013 and a first bottom plate 2014, the second connecting member 2013 is arranged between the first connecting member 2012 and the first bottom plate 2014, a plurality of cyclone separation cones 20131 are arranged in the second connecting member 2013, a plurality of hollow inserts 20121 extending into the interior of the cyclone separation cones 20131 are arranged on the first connecting member 2012, and a third hollow insert 20121 is arranged near the second end 102. End 20122, the side wall of each cyclone separation cone 20131 is provided with an air inlet 20132; the dirty air separated by the cyclone cover 202 enters the cyclone separation cone 20131 through the air inlet 20132 and rotates around the hollow insert 20121, and the dust particles in the dirty air separated by the cyclone cover 202 fall into the second ash storage chamber 204 through the bottom of the cyclone separation cone 20131, and the separated clean air is discharged through the third end 20122 of the hollow insert 20121. The hollow insert 20121 and the cyclone separation cone 20131 correspond one to one, and there is a gas circulation channel between the hollow insert 20121 and the cyclone separation cone 20131. The dirty air after the first step of cyclone separation rotates in the gas circulation channel, and the separated dust particles fall into the second ash storage chamber 204. The separated clean air is discharged through the third end 20122 of the hollow insert 20121, and is discharged into the atmosphere through the vacuum motor.

[0074] In one possible implementation, Figure 14-17 As shown, the first bottom plate 2014 is provided with a first opening 2022, and the dust cup assembly further includes a sealing member 307, and the sealing member 307 is used to close the first opening 2022. The first opening 2022 is provided on the first bottom plate 2014, which is equivalent to providing an ash discharge port for the second ash storage chamber 204. However, since the cyclone separator 201 needs to operate in a closed environment when performing cyclone separation on the dirty air in the cyclone separation part 200, in order to simultaneously meet the operations of ash discharge and cyclone separation, this embodiment is provided with both the first opening 2022 and the sealing member 307 that can open and close the first opening 2022.

[0075] In one possible implementation, Fig.14 and 15As shown, the sealing member 307 is connected to the scraping member 303 through the connecting plate 308. When the driving member 301 drives the connecting rod 302 to drive the scraping member 303 to move, the sealing member 307 moves with the scraping member 303. The sealing member 307 and the scraping member 303 are connected by the connecting plate 308, so that when the driving member 301 drives the connecting rod 302 to move, the scraping member 303, the connecting plate 308 and the sealing member 307 will all move together. As mentioned above, this embodiment can simultaneously realize scraping and pouring out the dust. The pouring out of the dust here does not only mean pouring out the dust in the first ash storage chamber 203. If the driving member 301 drives the connecting rod 302 to open the dust cup cover 103, the dust in the second ash storage chamber 204 will also fall into the first ash storage chamber 203 at the same time. That is, through the first method of opening the dust cup cover 103 mentioned above, the pouring out and scraping of the first ash storage chamber 203 and the second ash storage chamber 204 can be realized at the same time.

[0076] In one possible implementation, Figure 5 and 19 As shown, the sealing member 307 includes an inner ring 3072 for blocking the first opening 2022, and an outer ring 3073 connected to the connecting plate 308, and the inner ring 3072 and the outer ring 3073 are connected by a third connecting member 3074. The outer ring 3072 and the third connecting member 3074 are arranged between the inner ring 3072 and the connecting plate 308 to make the connection more stable, the sealing ring 2021 is force-balanced and the sealing is stable, and the third connecting member 3074 is arranged in a rib position to prevent garbage from being stored between the inner ring 3072 and the outer ring 3073 during the ash dumping process. Furthermore, the outer ring 3073 is provided with a vertical plate structure to prevent dust from entering the second ash storage chamber 204 during the first step of cyclone separation.

[0077] In one possible implementation, Figure 4 and 5 As shown, a first guide rod 309 is provided between the seal 307 and the cyclone separator 201. The first guide rod 309 guides the movement of the seal 307 and the ash scraper 303, and also fixes the seal 307 to accurately block the second ash storage chamber 204.

[0078] In one possible implementation, Fig.15 and 16As shown, a magnetic block 2011 is further provided at the end of the cyclone separator 201 facing the seal 307, and an iron block 3071 is further provided at the corresponding position of the seal 307. The magnetic attraction between the magnetic block 2011 and the iron block 3071 ensures the stability of the seal 307 and the cyclone separator 201 when they are in contact, and further ensures the closed environment of the second ash storage chamber 204. In addition, the magnetic block 2011 and the iron block 3071 are provided, and the structure is simple, and it is also easier to operate when the dust in the second ash storage chamber 204 needs to be dumped.

[0079] In one possible implementation, Figure 5 and 14 As shown, the connecting plate 308 is provided with reinforcing ribs 3081. The reinforcing ribs 3081 can increase the structural strength of the connecting plate 308 and ensure the connection stability between the sealing member 307 and the scraping member 303.

[0080] In one possible implementation, Fig.16 and 17 As shown, a sealing ring 2021 is further provided at the connection between the cyclone separation part 200 and the sealing member 307. The sealing ring 2021 can improve the sealing performance between the cyclone cover 202 and the sealing member 307, and prevent the second ash storage chamber 204 from affecting the dust separation effect due to air leakage when performing cyclone separation.

[0081] In one possible implementation, the first bottom plate 2014 and the seal 307 are both inclined, which can facilitate dust to gather at the bottom of the cyclone separation section 200, so that when the seal 307 is opened, dust and the like can fall off quickly. At the same time, the inner ring 3072 of the seal 307 is designed to be conical, which is also convenient for better alignment and sealing with the opening 2022 when moving upward.

[0082] In one possible implementation, Figure 3 , 4 As shown in FIG. 17 , the cyclone separation unit 200 further includes a filter 205, which is disposed on one side of the cyclone separator 201 close to the first end 101. After the air entering the second ash storage chamber 204 is subjected to cyclone separation, there may still be fine dust particles that will be discharged from the cyclone separation unit 200. In order to prevent these dust particles from being discharged into the air, a filter 205 is further disposed in the cyclone separation unit 200 to block the above dust particles on the filter 205. When the dust particles reach a certain amount, the filter 205 only needs to be cleaned.

[0083] In one possible implementation, Fig. 20As shown, when the driving member 301 is pressed, the scraper 303 moves away from the filter 205, and the seal 307 moves away from the first opening 2022; until the driving member 301 is closest to the first end 101, the pressing portion 3021 contacts the first rotating arm 3042, the scraper 303 is farthest from the filter 205, and the seal 307 is farthest from the first opening 2022. The pressing portion 3021 contacts and pushes the first rotating arm 3042 to rotate close to the first end 101, while the second rotating arm 3044 rotates away from the first end 101, and the locking member 3043 gradually moves away from the locking protrusion 1031 to unlock, so that the dust cup cover 103 can be opened.

[0084] like Fig.21 As shown, this embodiment also provides a cleaning device, including the dust cup assembly described in the above embodiment, and the cleaning device also includes a floor brush 2, a handheld part 1 and a connecting pipe 3. The floor brush 2 is used to contact the surface to be cleaned, and the floor brush 2 includes a roller brush and a suction port. The connecting pipe 3 is used to connect the handheld part 1 and the floor brush 2, and provide a fluid channel and circuit connection between the two. The handheld part 1 includes a dust cup assembly 10, a vacuum motor 11 and a power supply 12. The power supply 12 can be a battery pack or a wiring connection to the mains. The power supply 12 provides power for the vacuum motor 11, the roller brush motor and other electrical equipment. The vacuum motor 11 provides vacuum suction, and the suction force acts on the suction port of the floor brush to pick up garbage on the surface to be cleaned. The dust cup assembly 10 is used to filter garbage. The clean air filtered by the dust cup assembly 10 is sucked into the air inlet of the vacuum motor 11 and discharged through the air outlet of the vacuum motor 11.

[0085] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, 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.

[0086] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which 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.
