Description

Technical Field

[0002] At present, the vacuum cleaner system usually includes a vacuum cleaner device (such as a vacuum cleaner) and a dust collection station. The vacuum cleaner can be used for dust extraction through the dust collection station, without the need for the user to manually empty the dust. The dust collection station is provided with a docking port, a dust bag for collecting dust, and a dust collection station motor that provides negative pressure for dust extraction. When the vacuum cleaner is docked with the docking port of the dust collection station, negative pressure is generated by the action of the dust collection station motor, which can extract the dust in the dust cup of the vacuum cleaner. In this way, the user does not need to empty the dust after each cleaning, and the user can empty the dust once a month or even longer. However, the dust in the dust bag in the vacuum cleaner device may adhere to the inner wall, resulting in residue and reducing the dust removal effect. Utility Model Content

[0057] See also Figures 1 to 6 The present invention provides a vacuum cleaner device. The vacuum cleaner device can be used in a vacuum cleaner system. In order to achieve better operation of the vacuum cleaner device, the vacuum cleaner system may further include a dust collection station.

[0058] The specific form of the vacuum cleaner device is not limited, and in actual application, the use orientation of the vacuum cleaner device may be different. However, for ease of understanding, in the following embodiments, Figures 1 to 6 The handheld vacuum cleaner device shown is used as an example for description. In this case, the vacuum cleaner device has a substantially vertical up-down direction and a horizontal direction.

[0059] In view of this, the vacuum cleaner device can generally be divided into multiple components according to its function, such as but not limited to the air inlet part 800 and the dust cup 100, and according to actual needs, it can also include a gripping part.

[0060] The air inlet 800 generally forms an air inlet duct, and the upstream of the air inlet duct can directly form the air inlet of the entire machine. According to actual needs, the air inlet 800 can also be equipped with some accessory brush heads for cleaning in different scenarios, such as pet brush heads, crevice brush heads, mite removal brush heads, etc.

[0061] A dust storage chamber 111 is formed inside the dust cup 100. The downstream of the air inlet duct can be connected to the upstream of the dust storage chamber 111. The dust storage portion can be configured as a columnar structure extending in the vertical direction. In this case, the air inlet portion 800 can be roughly arranged on one side of the dust cup 100 in the horizontal direction, and the air inlet portion 800 and the air inlet duct formed therein can be roughly arranged to extend in the horizontal direction.

[0062] An air outlet duct is generally formed inside the air outlet portion, and the upstream of the air outlet duct is connected to the downstream of the dust storage chamber 111. The downstream of the air outlet portion can generally directly constitute the air outlet of the entire machine, so that after the dust cup 100 traps the dirt in the air carrying dirt in the dust storage chamber 111, the air outlet portion discharges the relatively clean air outward through the air outlet. Of course, in specific applications, through structural design, the downstream opening of the dust cup 100 can be directly used as the air outlet, that is, the downstream cavity section of the dust cup 100 directly constitutes the air outlet duct.

[0063] The grip portion is the portion that the user holds to drive the entire device. There is no restriction on its specific structure, and it can be, but is not limited to, a rod or a ring.

[0064] like Figures 1 to 2 As shown, in order to make the structure of the whole machine compact, the dust cup 100 and the air outlet can be arranged to extend in a columnar shape along the up and down direction, and the air outlet is arranged above the dust cup 100. The air inlet 800 is arranged on one side of the dust cup 100 in the horizontal direction, and the grip is arranged on the other side of the dust cup 100 in the horizontal direction.

[0065] In view of the above, the vacuum cleaner device can at least be used for vacuuming. In order to achieve the purpose of gas entering the air inlet duct from the air inlet, passing through the dust cup 100 and the air outlet duct, and finally being discharged outward from the air outlet, in a specific application, the vacuum cleaner device also includes an air expelling device 600. The air expelling device 600 refers to any device that can achieve the purpose of driving the directional flow of gas, which can be composed of a single component (such as a fan) alone, or composed of at least two single components (such as a fan and an air guide structure). The air expelling device 600 may include a fan, which may be but not limited to an axial flow fan, a cross-flow fan, a centrifugal fan, etc. The air expelling device 600 generally has a suction side and an exhaust side under normal operating conditions. When started, the suction side of the air expelling device 600 forms a negative pressure, which can draw the external air flow into the inside of the air expelling device 600; the exhaust side forms a positive pressure, which can discharge the air flow inside the air expelling device 600 outward.

[0066] In actual application, the exhaust side of the air-exhausting device 600 can be connected to the air inlet to blow gas into the air inlet duct, so as to achieve the purpose of driving the gas from the air inlet into the air inlet duct, passing through the dust storage chamber 111 and the air outlet duct, and finally being discharged outward from the air outlet. However, in order to reduce the adverse effect of the setting of the air-exhausting device 600 on the air flow of the air inlet part 800, Figures 1 to 6 In the illustrated embodiments, the structure in which the air suction side of the air purging device 600 is connected to the downstream of the air outlet duct and the air discharge side of the air purging device 600 constitutes the air outlet of the entire machine is used as an example for illustration.

[0067] In addition, in order to realize the orderly operation of each component in the vacuum cleaner system, the vacuum cleaner system may further include a power supply device 700 and a control device. The power supply device 700 may include but is not limited to a one-time charge and discharge power supply device, such as a disposable battery; or the power supply device 700 may also include a repeatedly charge and discharge power supply device, such as a battery that can be electrically connected to the mains. The power supply device 700 may be arranged in the housing, for example, on the side of the air purging device 600 facing away from the air outlet / dust cup 100. The control device can at least be electrically connected to the power supply device 700 and the air purging device 600, so as to be able to control the charging and discharging of the power supply device 700, and control the air purging device 600 to start and stop running, and adjust the preset operating power according to actual needs, such as according to a preset program or in response to a user's trigger instruction. The control device can be built into the vacuum cleaner device, or it can be externally placed at, for example, a dust collection station or other location according to actual needs, and communicate with the air purging device 600 on the vacuum cleaner device, for example, through a wireless connection. As Figure 2 As shown, the power supply device 700 can be arranged on a side of the air purging device 600 away from the air inlet portion 800 and opposite to the air inlet portion 800 .

[0068] Furthermore, the vacuum cleaner and / or dust collection station may be provided with a display module and / or input device. The display module includes a display panel, which may display digitally or graphically, depending on actual needs. The input device may include, but is not limited to, physical or virtual buttons, a voice recognition module, a gesture recognition module, etc., allowing the user to manually enter relevant trigger commands.

[0069] Of course, depending on actual needs, the vacuum cleaner device and / or dust collection station may also be equipped with one or more sensor devices. The sensor devices are electrically connected to the control device so that the control device can intelligently control the operation of the corresponding functional components based on the sensing data of the sensor devices. For example, the sensor device can be located at the interface between the vacuum cleaner device and the dust collection station, and is triggered when the vacuum cleaner device and the dust collection station are connected to each other to generate a sensor signal.

[0070] A dust collection station is typically used in conjunction with a vacuum cleaner. The vacuum cleaner has a first operating state, in which it operates independently from the station, and a second operating state, in which it is docked with the station. In the second operating state, the station can perform various preset operations on the vacuum cleaner, driven by a preset program or in response to user triggers. These preset operations may include, but are not limited to, charging, cleaning, and dust removal.

[0071] Based on one or more of the above embodiments, please combine Figures 2 to 6The vacuum cleaner device includes a dust cup 100, which includes a cup body 110, a first cup cover 200, and a second cup cover 300. The cup body 110 has a first opening 112 at its bottom; the first cup cover 200 covers the first opening 112 and includes an elastic portion 220. The elastic portion 220 is configured to deform positively under an outward force to cause at least a portion of the first cup cover 200 to bulge outward. The first cup cover 200 has a second opening 210 at the bulging portion; the second cup cover 300 is movably mounted on the first cup cover 200 and can open and close the second opening 210.

[0072] In the technical solution provided by the present invention, a dust storage chamber 111 for storing dust and other dirt is formed in the cup body 110; the opening size of the second opening 210 is obviously smaller than the first opening 112, so that the design size of the second cup cover 300 can be more compact relative to the first cup cover 200, which helps to save materials; and the elastic portion 220 can drive at least a part of the first cup cover 200 to bulge outward under the driving force of the outward action. Since the second opening 210 is opened at the bulge, the second opening 210 and the second cover body will be driven to extend outward from the first opening 112. In this way, on the one hand, the first cup cover 20 The outward convex structure of 0 can form a conical guide surface in the dust storage chamber 111, which helps to guide the dirt on the side of the second opening 210 to the second opening 210, which is more conducive to the centralized discharge of the dirt; on the other hand, the outward convex structure of the first cup cover 200 drives the second opening 210 and the second cup cover 300 to extend further into the dust collecting chamber of the dust collection station, such as the dust collecting station, which is connected to the dust storage chamber 111, forming a concave-convex connection, which helps to ensure the accuracy and stability of the position of the connection, improve the sealing of the connection, and help to discharge the dirt in the dust storage chamber 111 more thoroughly and efficiently, thereby improving the dust discharge effect of the vacuum cleaner equipment.

[0073] Specific as Figures 2 to 4 As shown, the cup body 110 is roughly cylindrical and extends in the up and down directions, and a dust storage cavity 111 is formed inside. The side wall opening of the cup body 110 constitutes the upstream of the dust storage cavity 111, and is connected to the air inlet duct of the above-mentioned air inlet part 800; the top wall opening of the cup body 110 constitutes the downstream of the dust storage cavity 111, and is connected to the air outlet duct of the above-mentioned air outlet part. The bottom wall opening of the cup body 110 constitutes the first opening 112. The first opening 112 can cover the entire bottom wall of the cup body 110, or it can only cover a part of the bottom wall of the cup body 110.

[0074] The first cup cover 200 covers the first opening 112. It should be noted that the first cup cover 200 and the cup body 110 can be integrally formed. For example, the first cup cover 200 and the cup body 110 are integrally injection molded, or are formed from the same material through processes such as stamping and folding. Or the first cup cover 200 and the cup body 110 are non-detachably connected after being separately molded. For example, the first cup cover 200 and the cup body 110 are welded and fixed after being separately molded. At this time, the first cup cover 200 and the first opening 112 are connected and fixed, that is, the first opening 112 (except for the subsequent second opening 210) remains in a covered state. Or the first cup cover 200 and the cup body 110 are detachably connected after being separately molded. For example, the first cup cover 200 and the cup body 110 are snap-connected, magnetically connected, etc. after being separately molded. At this time, the first cup cover 200 and the first opening 112 have a covered state and an open state. Since the second opening 210 is formed in a local area of the first cup cover 200, the size of the second opening 210 is necessarily smaller than that of the first opening 112. This allows the cup body 110 to form a larger dust discharge area, similar to the first opening 112, when the first opening 112 is open. When the first opening 112 is closed and the second opening 210 is open, the cup body 110 can form a smaller dust discharge area, similar to the second opening 210. When both the first opening 112 and the second opening 210 are closed, the cup body 110 remains closed at the bottom wall. In this way, the same dust cup 100 can be formed with dust discharge areas of different positions and sizes according to actual needs.

[0075] The second cup cover 300 is movable to cover the second opening 210, ensuring that the dust cup 100 can open the second opening 210 through the second cup cover 300 to form a desired dust exhaust area regardless of whether the first opening 112 is open. The movement between the second cup cover 300 and the second opening 210 is not limited and can be translational and / or rotational according to actual needs.

[0076] The elastic part 220 is a structure made of a material with a certain elastic deformation ability. The material with elastic deformation ability can be but is not limited to rubber, silicone, etc., and can also be metal under certain size and shape restrictions. The outward force is a force applied from the inside of the dust storage chamber 111 to the outside of the dust storage chamber 111. When the first cup cover 200 is subjected to an outward force, the elastic part 220 produces positive deformation, such as elongation deformation, expansion deformation, etc. toward the outside of the dust storage chamber 111. When the elastic part 220 produces positive deformation, it will drive the remaining part of the first cup cover 200 connected to it to produce convex deformation as a whole or in part, and then drive the second opening 210 to extend outward beyond the first opening 112.

[0077] Specifically, the elastic portion 220 can be arranged to extend along the entire periphery of the second opening 210. If the elastic properties of the elastic portion 220 along the entire periphery of the second opening 210 remain consistent, the elastic portion 220 will deform the second opening 210 to a substantially uniform degree when subjected to an outward force. This allows the second opening 210 to extend entirely outside the first opening 112 while maintaining the orientation of the second opening 210 unchanged, i.e., maintaining the second opening 210 facing downward.

[0078] like Figure 6 As shown, if the elastic portion 220 is extended along the entire circumference of the second opening 210, there are differences in the elastic properties of various parts in the circumferential direction of the second opening 210. Or the elastic portion 220 is partially extended along the periphery of the second opening 210. At this time, when the elastic portion 220 is subjected to an outward force, there are differences in the degree of deformation produced on the circumferential side of the second opening 210, that is, deformation with a larger amount of deformation is produced locally, and deformation with a smaller amount of deformation is produced locally. The side of the second opening 210 corresponding to the deformation producing a larger amount of deformation extends outward from the first opening 112. The side of the second opening 210 corresponding to the deformation producing a smaller amount of deformation may remain in its original position, or extend outward from the first opening 112, but the extension is smaller. The direction of the second opening 210 changes, tilting toward the side producing a smaller amount of deformation. In this way, the second opening 210 changes from the original downward direction to an inclined direction, which helps to adapt to docking ports of different angles (such as the dust collecting port of the dust collecting chamber in the dust collecting station described below) and can convert the downward dust discharge direction to the side direction.

[0079] There are several specific configuration schemes for the elastic portion 220 to achieve the above purpose:

[0080] For example, the first cup cover 200 as a whole constitutes the elastic part 220. That is, the first cup cover 200 is made of elastic material as a whole, for example, it is made of rubber material or silicone material with sufficient strength; or it is made of metal sheet with sufficient strength. In this way, when subjected to an outward force, the first cup cover 200 as a whole produces an outward convex deformation, and the second opening 210 can be opened at any position of the first cup cover 200. Among them, when the outward force applied to various parts of the first cup cover 200 has certain differences in direction and magnitude, different parts of the first cup cover 200 will produce different degrees of convex deformation. At this time, according to actual needs, for example, the second opening 210 can be set at a part with a relatively greater degree of deformation.

[0081] Or for example, see Figure 5In one embodiment, the second opening 210 is provided in the elastic portion 220 . The first cup cover 200 further includes a first rigid portion 230 disposed along the periphery of the elastic portion 220 , and the first rigid portion 230 is fixedly connected to the cup body 110 . It should be noted that the first rigid portion 230 refers to a structure having a stiffness at least greater than that of the elastic portion 220 . In practical applications, the first rigid portion 230 and the elastic portion 220 can be made of different materials and then fixedly connected; or the first rigid portion 230 and the elastic portion 220 can be made of the same material, and then the first rigid portion 230 can be treated to increase its stiffness, such as by increasing its thickness or adjusting its molding process; and / or the elastic portion 220 can be treated to decrease its stiffness, such as by reducing its thickness or adjusting its molding process. In this way, when subjected to an outward force, the elastic portion 220 can produce the desired positive deformation, and the first rigid portion 230 can minimize deformation to ensure a secure connection to the cup body 110 .

[0082] Or for example, see Figures 3 and 4 In one embodiment, the first cup cover 200 further includes a second rigid portion 240 and a third rigid portion 250. The second rigid portion 240 is provided with a second opening 210. The third rigid portion 250 is disposed along the periphery of the second rigid portion 240 and is fixedly connected to the cup body 110. The elastic portion 220 is connected between the second rigid portion 240 and the third rigid portion 250. Similarly to the above, the stiffness of the second rigid portion 240 and the third rigid portion 250 is at least greater than that of the elastic portion 220. The stiffness of the second rigid portion 240 and the third rigid portion 250 can be consistent or different. For example, the stiffness of the third rigid portion 250 can be greater than that of the second rigid portion 240. By configuring the second rigid portion 240, the third rigid portion 250, and the elastic portion 220, when subjected to an outward force, the elastic portion 220 can produce the desired positive deformation, driving the second rigid portion 240 to extend outward from the first opening 112. Because the second rigid portion 240 has sufficient rigidity, it helps to reduce the effect of the elastic portion 220 on the orientation and size of the second opening 210, maintaining the orientation and size of the second opening 210 substantially unchanged compared to before deformation. Similarly, the third rigid portion 250, like the first rigid portion 230, can minimize deformation and ensure a secure connection with the cup body 110.

[0083] In addition, based on any of the above embodiments, the elastic portion 220 may refer to a unidirectional deformation structure that can produce positive deformation when subjected to an outward force, thereby ultimately driving the first cup cover 200 to at least partially produce a convex deformation. Furthermore, the elastic portion 220 may also be a bidirectional deformation structure that produces negative deformation when subjected to an inward force, thereby ultimately driving the first cup cover 200 to at least partially produce a concave deformation. Wherein, the inward force is also the force applied from the outside of the dust storage chamber 111 toward the inside of the dust storage chamber 111. When the first cup cover 200 is subjected to an inward force, the elastic portion 220 produces a negative deformation, such as a shortening deformation, a compression deformation, etc. toward the inside of the dust storage chamber 111. When the elastic portion 220 produces a negative deformation, it will drive the entire or partial concave deformation of the remaining portion connected to it on the first cup cover 200, and then drive the second opening 210 to extend inward into the dust storage chamber 111.

[0084] As for the configuration of the elastic portion 220 for achieving the above-mentioned concave deformation, the specific reference may be made to the above-mentioned elastic portion 220 for achieving the convex deformation, and detailed description thereof will be omitted.

[0085] In view of the above, when applying to vacuum cleaner equipment, please combine Figures 3 and 4 The vacuum cleaner device also includes a cyclone cup 400 and a filter 500. The bottom of the cyclone cup 400 is provided with a third opening 421, and the cyclone cup 400 is placed in the cup body 110, and defines a first cavity section 111a between the cyclone cup 400 and the cup body 110; the filter 500 is provided in the first cavity section 111a and is located upstream of the cyclone cup 400 in the air flow path; when the first cup cover 200 is partially convex, the third opening 421 is connected to the first opening 112 and / or the second opening 210 through the first cavity section 111a; and when the first cup cover 200 is partially concave, the first cup cover 200 and / or the second cup cover 300 abuts against the bottom of the cyclone cup 400 and covers the third opening 421. The cyclone cup 400 includes a cyclone device 410 and a cup body 420, and a second cavity section 422 is formed inside the cup body 420. When external airflow enters cyclone cup 400, the centrifugal force generated by the rotation of cyclone element 410 separates dust and impurities from the air and collects them in cup body 420. Cyclone element 410 may be, for example, but not limited to, a multi-cone filter. Filter element 500 may be, for example, a filter mesh disposed around cyclone cup 400.

[0086] When external air enters the dust storage chamber 111 through the air inlet duct, it first undergoes primary filtration through the filter element 500, with the retained dirt being stored in the first chamber section 111a. The filtered air then flows into the cyclone cup 400, where it undergoes secondary filtration through the cyclone element 410, with the retained dirt being stored in the second chamber section 422.

[0087] Since the cup body 420 generally extends downward to approach or abut the first cup cover 200, when subjected to an outward force, the first cup cover 200 is partially deformed to convex outward, which is equivalent to making way, and sufficient space is reserved below the cup body 420, so that the first cavity section 111a and the second cavity section 422 can be changed from a partition to a connection, or the first cavity section 111a and the second cavity section 422 can be changed from a small space connection to a large space connection, so that when the second cup cover 300 opens the second opening 210, the dirt in the first cavity section 111a and the second cavity section 422 can be simultaneously guided to the second opening 210 through the convex structure and discharged outward.

[0088] When subjected to an inward force, the first cup cover 200 partially deforms inward, which is equivalent to forming a bulge in the dust storage chamber 111. The bulge is close to the cup body 420, driving the first cup cover 200 and / or the second cup cover 300 to abut the bottom of the cyclone cup 400 and cover the third opening 421. In this way, the first cup cover 200 and the second cup cover 300 can simultaneously cover the first opening 112, the second opening 210 and the third opening 421, and the cyclone cup 400 and the dust cup 100 are separated to achieve independent dust storage.

[0089] Furthermore, the orthographic projection of the third opening 421 on the first cup cover 200 at least partially overlaps with the second opening 210, so that when the first cup cover 200 produces a convex deformation, the dirt in the first cavity section 111a and the dirt in the second cavity section 422 can be discharged directly outward through the second opening 210. Furthermore, the orthographic projection of the third opening 421 on the first cup cover 200 can completely cover the second opening 210. In this way, on the one hand, it helps to enhance the discharge effect of the dirt in the second cavity section 422; on the other hand, when the first cup cover 200 produces a concave deformation, the ridge formed by the concave structure in the dust storage chamber 111 just extends into the second cavity section 422 through the third opening 421, which is equivalent to forming a blocking structure, which further helps to enhance the sealing effect of the third opening 421.

[0090] In addition, by designing the position and size of the elastic portion 220 and the third opening 421, when the first cup cover 200 is partially concave, the elastic portion 220 can seal against the bottom of the cyclone cup 400. In this way, when the first cup cover 200 is concave, the elastic portion 220 forms an elastic sealing ring, which at least helps to seal the third opening 421.

[0091] In view of the above, the opening or closing action of the second cup cover 300 on the second opening 210 can be associated with the convex deformation and / or concave deformation of the first cup cover 200, for example, through a linked mechanical structure, program control, sensor induction triggering, etc.

[0092] In which, when driven by an outward force, the first cup cover 200 produces a convex deformation as described above, and simultaneously or later, the second cup cover 300 moves to open the second opening 210, so that the dirt in the first cavity section 111a and the second cavity section 422 can be discharged outward through the second opening 210. And / or, under the drive of an inward force, the first cup cover 200 produces a concave deformation as described above, and simultaneously or in advance, the second cup cover 300 moves to cover the second opening 210, ensuring that the first cavity section 111a and the second cavity section 422 remain sealed.

[0093] It should be noted that in order to prevent the second cup cover 300 from abnormally opening the second opening 210 under the driving of the inward force, in one embodiment, the first cup cover 200 and / or the second cup cover 300 are provided with a limiting structure. Under the driving of the inward force, the limiting structure limits the second cup cover 300 from moving to open the second opening 210. Specifically, the limiting structure can be a barrier portion provided on the side of the second cup cover 300 facing the dust storage chamber 111. The barrier portion can be arranged along the entire circumference of the second cup cover 300, or can be locally protruded along the circumference of the second cup cover 300. Alternatively, the limiting structure can also be a magnetic portion provided on the side of the second cup cover 300 facing the dust storage chamber 111. The magnetic portion is made of a magnetic material and can be magnetically fixed to the second cup cover 300 containing iron, cobalt and nickel, or magnetically fixed to a matching portion containing iron, cobalt and nickel provided on the second cup cover 300, and the like.

[0094] It should be noted that the inward force and / or outward force in the above embodiments can be applied to the dust cup 100 in any suitable form. However, in one application, when the vacuum cleaner system includes the vacuum cleaner device and the dust collection station as described above, the vacuum cleaner includes the air purging device 600 as described above, and the dust collection station is provided with a dust collection chamber.

[0095] Among them, when the vacuum cleaner device is operating normally, for example, when it is in the first working state as mentioned above, the air removal device 600 acts solely on the dust cup 100 to form a dust suction path from the air inlet duct, through the dust storage chamber 111, to the air outlet duct. At the same time, a negative pressure is generated in the dust cup 100, and the negative pressure also forms an inward force acting on the first cup cover 200 and / or the second cup cover 300. At this time, the first cup cover 200 and / or the second cup cover 300 synchronously cover the above-mentioned first opening 112, the second opening 210 and the third opening 421 to ensure that the airflow does not leak out from the bottom wall of the dust cup 100, and only flows along the above-mentioned dust suction path.

[0096] When in the second working state as described above, the vacuum cleaner device is docked with the dust collection station, and the vacuum cleaner system has a dust exhaust duct connecting the dust collection chamber and the dust cup 100. The air purging device 600 generates a negative pressure in the dust collection chamber and forms an outward force acting on the first cup cover 200 and / or the second cup cover 300 to suck the dirt in the dust cup 100 into the dust collection chamber through the dust exhaust duct. When the air purging device 600 acts on the dust collection chamber and generates a negative pressure in the dust collection chamber, if the dust collection chamber and the dust cup 100 remain in a conductive state or are switched to a conductive state, it can be set so that the negative pressure can collect the dirt in the dust cup 100 into the dust collection chamber, completing the dust exhaust operation. In this way, it is only necessary to set up the purge device 600 on the vacuum cleaner device, without additionally setting up other purge devices in the dust collection station. After the vacuum cleaner device and the dust collection station are docked, the purge device 600 can be reused to achieve the purpose of transferring the dirt in the dust cup 100 to the dust collection chamber for dust removal operation, which has the characteristics of simplified overall structure, simple operation, and low maintenance cost. At the same time, due to the negative pressure generated in the dust collection chamber, the outward force acting on the first cup cover 200 and / or the second cup cover 300 is formed, which can cause the first cup cover 200 to at least partially produce a convex deformation, and can cause the second cup cover 300 to move to open the second opening 210, which is more conducive to the dust removal operation and improves the dust removal effect.

[0097] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
