Description

Technical Field

[0001] This disclosure relates to the field of cleaning equipment technology, and more specifically, to a dust collection device, cleaning equipment, and cleaning system. Background Technology

[0002] Cleaning equipment, such as vacuum cleaners, uses negative pressure to suck dust and other contaminants into a dustbin. Existing vacuum cleaners often incorporate a cyclone separator within the dustbin to separate and retain dust. Sealing elements are needed on the dustbin lid to seal the two spaces inside and outside the cyclone separator. Current technology uses rigid materials like hard rubber and foam for these sealing elements, sealing the cyclone separator through an interference fit. However, closing the dustbin requires a force greater than the interference fit resistance. Therefore, when users manually clean the vacuum cleaner or use a vacuum cleaner base station with a dust collection function, they must manually close the dustbin lid, or a separate device within the base station is needed to close the lid. This results in a poor user experience and increases the complexity and manufacturing cost of the base station. Utility Model Content

[0004] A first aspect of this disclosure provides a dust collection device, comprising: a housing having an internal accommodating space; an end cap rotatably disposed at one end of the housing and configured to block the accommodating space; a separator disposed within the accommodating space, the separator having a dust collection channel facing the end cap, the dust collection channel being configured to partially isolate the accommodating space; and a sealing assembly disposed on the end cap, the sealing assembly having a sealing element, the sealing element being an elastic structural member, the upper part of the sealing element blocking the dust collection channel, and the lower part of the sealing element communicating with the atmosphere.

[0005] In some embodiments, the dust collection device includes a filter assembly disposed at the other end of the separator relative to the sealing assembly.

[0006] In some embodiments, the dust collection device includes a vacuum motor, and the seal moves toward the dust collection channel and seals the second accommodating space when the suction force of the vacuum motor is not less than 1 kPa.

[0007] In some embodiments, the seal may expand upward or retract downward relative to the dust collection channel.

[0008] In some embodiments, the dust collection device includes a control switch disposed on the housing, the control switch having a first control state and a second control state, configured to restrict the rotation of the end cap.

[0034] To make the objectives, technical solutions, and advantages of this disclosure clearer, the disclosure will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

These terms are only used to distinguish the described objects. For example, first may also be referred to as second without departing from the scope of embodiments of this disclosure, and similarly, second may also be referred to as first. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] It should be understood that the term "and / or" as used herein is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. The singular forms "a," "the," and "the" are also intended to include the plural forms unless the context clearly indicates otherwise.

[0038] It is further understood that the terms “center,” “longitudinal,” “lateral,” “front,” “rear,” “up,” “down,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this embodiment and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0039] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0040] Depending on the context, the words “if” or “suppose” as used here can be interpreted as “when” or “in response to determination” or “in response to detection.” Similarly, depending on the context, the phrases “if determination” or “if detection (of the stated condition or event)” can be interpreted as “when determination” or “in response to determination” or “when detection (of the stated condition or event)” or “in response to detection (of the stated condition or event).”

[0041] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that an article or device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such an article or device. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the article or device that includes said element.

[0042] In related technologies, the cleaning equipment with dust collection base stations currently on the market requires the user or a device installed in the base station to close the bottom cover of the dust box after dust collection, which increases the user's operating costs or the complexity and manufacturing costs of the base station.

[0043] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a dust collection device, cleaning equipment, and cleaning system. The dust collection device includes: a housing with an internal receiving space; an end cap rotatably disposed at one end of the housing and configured to block the receiving space; a separator disposed within the receiving space, the separator having a dust collection channel facing the end cap, the dust collection channel being configured to partially isolate the receiving space, the space between the dust collection channel and the housing being a first receiving space, and the space inside the dust collection channel being a second receiving space; and a sealing assembly disposed on the end cap, the sealing assembly having a sealing element, the sealing element being an elastic structural element, the upper part of the sealing element blocking the dust collection channel, and the lower part of the sealing element communicating with the atmosphere.

[0044] The dust collection device, cleaning equipment, and cleaning system disclosed herein utilize a sealing element on one side of the end cap that communicates with the atmosphere. Whether through an interference fit between the sealing element and the dust collection channel, or by using negative pressure adsorption, there is no resistance to closing the end cap. Therefore, after the cleaning equipment completes dust collection on the operating surface, during the dust removal process, the user does not need to manually open the dust collection device, nor is there a need for complex closing force devices within the base station. Simply placing the cleaning equipment inside the base station opens the end cap of the dust collection device, achieving contactless dust disposal. After the cleaning equipment leaves the base station, the end cap automatically closes without the need for additional closing assistance devices on the base station. Furthermore, the sealing element, with one side communicating with the atmosphere, effectively seals the dust collection channel through interference fit or negative pressure adsorption. The dust collection equipment disclosed herein has the advantages of simple structure, excellent sealing effect, and easy operation, facilitating convenient user operation and improving the user experience.

[0045] The optional embodiments of this disclosure are described in detail below with reference to the accompanying drawings.

[0046] A first aspect of this disclosure provides a dust collection device 1000, including: a housing 1100, an end cap 1200, and a control switch 1400.

[0047] To more clearly describe the operation of the dust collection device 1000, the following directions are defined with reference to the dust collection device 1000: front-rear axis X, lateral axis Y, and central vertical axis Z. The front-rear axis X is essentially along the width of the dust collection device 1000. The direction opposite to the arrow on the front-rear axis X, i.e., the direction of backward movement of the dust collection device 1000, is labeled "reverse," and the direction along the arrow on the front-rear axis X, i.e., the direction of forward movement of the dust collection device 1000, is labeled "forward." The direction of the front-rear axis X is the first direction. The lateral axis Y is essentially along the length of the dust collection device 1000. The direction opposite to the arrow on the lateral axis Y is labeled "leftward," and the direction along the arrow on the lateral axis Y is labeled "rightward." The direction of the lateral axis Y is the third direction. The vertical axis Z extends vertically along the self-moving device. The direction opposite to the arrow on the vertical axis Z is labeled "downward," and the direction along the arrow on the vertical axis Z is labeled "upward." The direction of the vertical axis Z is the second direction.

[0048] In some embodiments, such as Figure 1 As shown, the dust collection device 1000 includes a filter assembly 1530, which is disposed at the other end of the separator 1510 opposite to the sealing assembly 1600. The filter assembly 1530 and the sealing assembly 1600 are combined to achieve a good seal of the containment space inside the dust collection device housing, preventing dirt within the containment space from escaping into the environment. Furthermore, Figure 1 The filter assembly 1530 shown is disposed close to the air outlet 1002, but this disclosure does not limit this. The filter assembly 1530 only needs to be disposed at the other end of the separator 1510 relative to the sealing assembly 1600, and the number of filter assemblies 1530 can also be multiple.

[0049] In some embodiments, such as Figures 1 to 3As shown, the housing 1100 has an internal accommodating space for accommodating components such as the vacuum motor and separator 1510. When the suction power of the vacuum motor is not less than 1 kPa, the seal 1610 moves towards the dust collection channel 1520 and seals the lower opening of the dust collection channel 1520. Specifically, due to insufficient manufacturing or assembly precision, after the end cap 1200 and housing 1100 are closed, there may be a gap between the seal 1610 and the lower opening of the dust collection channel 1520. This may result in the seal 1610 failing to properly seal the lower opening of the dust collection channel 1520. Therefore, when the vacuum motor starts working, regardless of the material or shape of the seal 1610, it needs to move or expand towards the dust collection channel 1520 when the suction power of the vacuum motor is greater than or equal to 1 kPa to seal the lower opening of the dust collection channel 1520. Specifically, the material of the seal 1610 can be ultra-soft rubber (10-20 Shore A hardness value), soft rubber (30-50 Shore A hardness value), or medium-hardness rubber (60-80 Shore A hardness value), etc. Regarding the material and shape of the seal 1610, the harder the material and the worse the elasticity, the larger the size of the seal 1610 needs to be, while the thickness needs to be reduced accordingly. For example, a soft rubber seal 1610 needs to have a larger projected area and a smaller thickness in the axial direction of the dust collection channel than an ultra-soft rubber seal 1610, so that the seal 1610 has good elasticity, thus allowing it to move or expand into the dust collection channel 1520 when the suction force of the vacuum motor is greater than or equal to 1 kPa. Conversely... The suction power of the vacuum motor can also be adjusted according to the material, shape, or size of the seal 1610. For example, for seals of the same size and shape, a seal 1610 made of soft rubber requires a greater suction power than a seal 1610 made of ultra-soft rubber. For example, the former requires a suction power of 1 kPa or greater than or equal to 1 kPa, while the latter requires a suction power of 3 kPa or greater. Thus, the suction power of the corresponding vacuum motor can be adjusted according to the material, size, or shape of the seal 1610 to achieve a good seal between the seal 1610 and the lower opening of the dust collection channel 1520.

[0050] In some embodiments, such as Figure 1As shown, an air inlet 1001 and an air outlet 1002 are provided on the side wall of the housing 1100. The air inlet 1001 and the air outlet 1002 are respectively located on different sides of the housing 1100 to extend the air path inside the housing 1100 and fully utilize the dust collection efficiency of the dust collection device 1000. A filter assembly 1530 is provided between the separator 1510 and the air outlet 1002 to prevent dust in the containment space from being directly blown out through the air outlet 1002 and polluting the clean environment. In some other embodiments, the air inlet 1001 and the air outlet 1002 may also be located on the same side of the housing 1100, and this disclosure does not limit this.

[0051] In some embodiments, such as Figure 1 As shown, the separator 1510 is located inside the housing 1100 and includes multiple or multi-stage dust separators 1510 and a dust collection channel 1520. The separator 1510 is configured to separate large dust particles from small dust particles, allowing only small dust particles to enter the dust collection channel 1520.

[0052] In some embodiments, such as Figure 1 As shown, the containment space includes a first containment space 1101 and a second containment space 1102. The first containment space 1101 is disposed inside the housing 1100 and communicates with the air inlet 1001, and is configured to contain dust sucked in by the operating surface; the second containment space 1102 is disposed inside the first containment space 1101. Specifically, the second containment space 1102 is located inside the dust collection channel 1520, and is configured to contain small particulate impurities separated by the separator 1510, thereby isolating large dust particles from small dust particles.

[0053] In some embodiments, such as Figure 1 As shown, the containing space has an open state and a closed state. When the containing space is in the open state, both the first containing space 1101 and the second containing space 1102 are connected to the outside, and the dust inside the first containing space 1101 and the second containing space 1102 can be dumped outside the dust collection device 1000, thus cleaning the inside of the dust collection device 1000. When the containing space is in the closed state, the dust inside the first containing space 1101 and the second containing space 1102 is collected inside the housing 1100. Normally, the first containing space 1101 and the second containing space 1102 are simultaneously in either the open state or the closed state.

[0054] In some embodiments, such as Figure 1As shown, the dust collection device 1000 also includes an end cover 1200, which is rotatably disposed on the housing 1100. It has an open position that opens the receiving space and a closed position that closes the receiving space. The end cover 1200 is configured to seal the receiving space so that dust from the operating surface is sucked into the receiving space and does not overflow into the external clean environment.

[0055] In some embodiments, such as Figure 1 As shown, the dust collection device 1000 also includes a reset member 1300, which is disposed between the end cover 1200 and the housing 1100, configured to movably connect the end cover 1200 and the housing 1100. The reset member 1300 has a tendency to rotate the end cover 1200 from an open position to a closed position. That is, without external force, the reset member 1300 usually keeps the end cover 1200 in the closed position. The reset member 1300 can be an elastic structural member, for example, a torsion spring. Furthermore, the reset member 1300 may also include magnetic elements respectively disposed on the end cover 1200 and the housing 1100, which hold the end cover 1200 in the closed position through the attraction between the magnetic elements.

[0056] In some embodiments, such as Figure 1 As shown, a limiting part 1110 is provided on the housing 1100. The limiting part 1110 protrudes from the side wall of the housing 1100 and is configured to restrict the movement of the end cover 1200. In response to the end cover 1200 being in the open / closed position, at least a portion of the end cover 1200 is engaged with the limiting part 1110, at which time the receiving space is closed. In response to the end cover 1200 being in the open position, the end cover 1200 is separated from the limiting part 1110, at which time the receiving space is open.

[0057] It should be noted that, as Figure 1 As shown, the reset capability of the reset member 1300 is sufficient to reset the end cover 1200 from the open position to the closed position. That is, when the end cover 1200 is switched from the open position to the closed position under the action of the reset member 1300, at least a portion of the end cover 1200 is engaged with the limiting part 1110.

[0058] In some embodiments, such as Figure 1 As shown, the end cap 1200 can be a double-layer structure, including a first plate 1211 and a second plate 1212. The first plate 1211 and the second plate 1212 are stacked in the thickness direction of the dust collection device 1000. The first plate 1211 is adjacent to the receiving space, and the second plate 1212 is disposed on the side of the first plate 1211 away from the receiving space. It should be noted that this disclosure is not limited to this. The end cap 1200 can be a single-layer structure or a three-layer structure. Whether the end cap 1200 is a single-layer or multi-layer structure, it has no impact on the technical solution of this disclosure.

[0059] In some embodiments, such as Figure 1 As shown, a first through hole 1201 is provided through the surface of the end cap 1200, and the first through hole 1201 is configured to communicate the receiving space with the outside. The sealing assembly 1600 can be installed in the first through hole 1201 so that the sealing assembly 1600 blocks the second receiving space 1102 and prevents small dust particles in the second receiving space 1102 from entering the first receiving space 1101.

[0060] In some embodiments, such as Figure 1 As shown, the dust collection device 1000 also includes a control switch 1400, which is disposed in the housing 1100. The control switch 1400 has a first control state and a second control state, and is configured to restrict the rotation of the end cover 1200. In response to the control switch 1400 being in the first control state, the end cover 1200 is normally in the closed position; in response to the control switch 1400 being in the second control state, the end cover 1200 can be switched from the closed position to the open position.

[0061] Specifically, such as Figure 1 As shown, the control switch 1400 is rotatable relative to the housing 1100 and is configured to control the engagement of the end cover 1200 and the limiting part 1110. In response to the control switch 1400 being in a first control state, the latching end 1210 of the end cover 1200 is engaged with the limiting part 1110, and the end cover 1200 is in a closed position. In response to the control switch 1400 being in a second control state, the latching end 1210 will disengage from the limiting part 1110 under the action of the control switch 1400. That is, when the control switch 1400 is in the second control state, the end cover 1200 is switched from the closed position to the open position.

[0062] In some embodiments, such as Figure 1 As shown, the two ends of the end cover 1200 are a snap-fit ​​end 1210 and a push-off end 1220, respectively. Specifically, the snap-fit ​​end 1210 is disposed on the side of the end cover 1200 near the control switch 1400. At least a portion of the snap-fit ​​end 1210 extends toward the control switch 1400 and is configured to engage with the limiting portion 1110 of the side wall of the housing 1100 to close the receiving space.

[0063] In some embodiments, such as Figure 1 As shown, the push end 1220 is disposed on the side of the end cover 1200 away from the control switch 1400. The push end 1220 can be disposed on the end cover 1200. The push end 1220 extends toward the side away from the fastening end 1210. At least a portion of the push end 1220 extends out of the side wall of the housing 1100 so that when an external force is applied to the push end 1220, the end cover 1200 and the housing 1100 can rotate relative to each other, thereby realizing the switching of the end cover 1200 between the open position and the closed position.

[0064] In some embodiments, such as Figure 1 As shown, the reset member 1300 is disposed on the side of the end cover 1200 adjacent to the push end 1220. When the end cover 1200 is in the closed position, in response to an external force applying an upward force in the thickness direction to the push end 1220, the end cover 1200 can switch from the closed position to the open position. Due to the action of the reset member 1300, when the external force applied to the push end 1220 is removed, the end cover 1200 switches from the open position to the closed position.

[0065] In some embodiments, such as Figure 1 As shown, the control switch 1400 is a lever structure with a first elastic element 1420. The control switch 1400 includes a locking key 1410 and the first elastic element 1420. The locking key 1410 is located on the outside of the housing 1100 adjacent to the open opening of the receiving space. The first elastic element 1420 is located between the locking key 1410 and the housing 1100, configured to reset the locking key 1410. Wherein, as... Figure 2 As shown, a shaft 1413 is provided through the middle of the locking key 1410. The shaft 1413 is fixedly connected to the housing 1100, which allows the locking key 1410 to rotate relative to the shaft 1413. Furthermore, the locking key 1410 has a power arm 1411 and a resistance arm 1412. A first elastic element 1420 is disposed between the power arm 1411 and the housing 1100. When no external force is applied to the power arm 1411, the control switch 1400 is in the first control state. At this time, the first elastic element 1420 is relaxed, and the end of the resistance arm 1412 away from the shaft 1413 abuts against the fastening end 1210. In response to an external force applied to the power arm 1411 and the first elastic element 1420 being compressed, the control switch 1400 is in the second control state. The end of the resistance arm 1412 away from the shaft 1413 tilts upward in the direction away from the housing 1100, thereby pushing the fastening end 1210 and releasing the engagement between the fastening end 1210 and the limiting part 1110.

[0066] In some embodiments, such as Figure 1 As shown, the dust collection device also includes a sealing component 1600, which is disposed on the end cover 1200 and configured to block the second receiving space 1102, thereby isolating the second receiving space 1102 from the first receiving space 1101. Specifically, a first through hole 1201 is provided through the surface of the end cover 1200, and the sealing component 1600 is connected to the first through hole 1201.

[0067] In some embodiments, such as Figures 1 to 4As shown, the sealing assembly 1600 includes: a seal 1610. The seal 1610 is an elastic structural member configured to block the receiving space. The seal 1610 is installed in a first through hole 1201 on the surface of the end cap 1200. Furthermore, the seal 1610 can expand upward or retract downward relative to the dust collection channel 1520.

[0068] In some embodiments, such as Figures 1 to 4 As shown, the sealing assembly 1600 also includes a support base 1620, which is disposed between the seal 1610 and the end cap 1200, and configured to support the seal 1610. Specifically, as... Figure 3 , Figure 4 As shown, the support base 1620 can be mounted on the end cover 1200 via the claw structure 1630. A second through hole 1602 is provided through the middle of the support base 1620. The sealing member 1610 is connected to the support base 1620 and covers the second through hole 1602. The sealing member 1610 includes a connecting part and a blocking part. The connecting part is connected to the support base 1620, and the blocking part is configured to block the dust collection channel 1520. In response to the end cover 1200 being in the open position, there is a gap between the sealing member 1610 and the end of the dust collection channel 1520 away from the separator 1510; in response to the end cover 1200 being in the closed position, the sealing member 1610 and the end of the dust collection channel 1520 away from the separator 1510 are sealed. The diameter of the blocking part of the sealing member 1610 is larger than the diameter of the dust collection channel 1520, which can effectively seal small dust particles within the second receiving space 1102.

[0069] In some embodiments, such as Figure 3 , Figure 4 As shown, the sealing assembly 1600 includes a first support 1621, which is disposed on the side of the support base 1620 facing the receiving space and configured to support the seal 1610. This prevents excessive deformation or positional displacement of the seal 1610 during the process of sealing the dust collection channel 1520.

[0070] In some embodiments, such as Figure 3 , Figure 4As shown, the sealing assembly 1600 includes a second support member 1622, which is disposed through the second through hole 1602 of the mounting base. The second support member 1622 is configured to limit the deformation of the seal 1610. If the deformation of the seal 1610 is too large, the seal 1610 may collapse excessively, leading to a gap in the connection between the seal 1610 and the dust collection channel 1520 port, resulting in incomplete sealing and leakage of dust from the second accommodating space 1102. The second support member 1622 can be disposed on the inner wall of the vent. The second support member 1622 is closer to the vent than the first support member 1621. The first support member 1621 and the second support member 1622 work together to prevent the seal 1610 from collapsing excessively and blocking the vent.

[0071] In some embodiments, such as Figure 3 , Figure 4 As shown, the seal 1610 is generally frustum-shaped, with its top surface being a generally circular plane to fit against the dust collection channel 1520. The side of the seal 1610 is supported by the first support member 1621. When the end cap 1200 is closed, if the dust collection channel 1520 abuts against the seal 1610, the first support member 1621 can divide the force of the dust collection channel 1520 pressing down on the seal 1610 into a vertical component and a horizontal component, thereby further reducing the resistance brought by the seal 1610 when the end cap 1200 is closed. Alternatively, the shape of the seal 1610 can also be generally conical or generally hemispherical, etc., and this disclosure does not limit this. In some embodiments, such as... Figure 3 , Figure 4 As shown, the seal 1610 and the support 1620 can be riveted, glued, or connected by a snap-fit ​​with complementary shapes, etc., and this disclosure does not limit them.

[0072] In some embodiments, such as Figure 3 , Figure 4 As shown, the lower part of the sealing assembly 1600 has an exhaust space communicating with the outside atmosphere. The support base 1620 of the sealing assembly 1600 is provided with a second through hole 1602, and the exhaust space communicates with the second through hole 1602. When the end cover 1200 is switched from the open position to the closed position, the seal 1610 blocks the dust collection channel 1520. Because the seal 1610 moves to block the dust collection channel 1520, it undergoes elastic deformation, and simultaneously, the pressure in the exhaust space changes. In response to the seal 1610 blocking the dust collection channel 1520, the pressure in the exhaust space decreases. Due to the second through hole 1602, the exhaust space is connected to the atmosphere, thereby allowing the seal 1610 to smoothly exhaust air from the exhaust space into the atmosphere, reducing the closing resistance of the seal 1610 on the end cover 1200.

[0073] Specifically, in response to the elastic deformation of the seal 1610, the seal 1610 fits more tightly with the dust collection channel 1520, preventing the dust collected in the dust collection channel 1520 from overflowing. In addition, the venting action of the seal 1610 will also reduce the resistance to closing the end cover 120. Under the action of the reset member 1300, the end cover 1200 can more tightly seal the receiving space.

[0074] In response to the sealing element 1610 blocking the dust collection channel 1520, the second accommodating space 1102 is sealed. When the dust collection device performs negative pressure adsorption on the surface of the operating surface during operation, a negative pressure is generated inside the first accommodating space 1101 and the second accommodating space 1102, which causes the sealing element 1610 to bulge towards the dust collection channel 1520 under air pressure. The elastic deformation of the sealing element 1610 ensures that the dust collection channel 1520 is well sealed.

[0075] In some embodiments, the seal 1610 can be directly disposed on the end cap 1200, specifically, such as Figure 5 As shown, the sealing element 1610 is a hollow hemispherical structure. The sealing element 1610 is disposed around the first through hole 1201 to fasten the first through hole 1201, thus isolating the first through hole 1201 from the accommodating space. The internal space of the hemispherical structure is connected to the outside of the end cap 1200. When the sealing element 1610 seals the dust collection channel 1520 using an interference fit, because the sealing element 1610 is an elastic structural component, it undergoes elastic deformation when sealing the dust collection channel 1520. In response to this elastic deformation, at least a portion of the air inside the hemispherical structure is discharged to the outside, thereby allowing the sealing element 1610 to seal the dust collection channel 1520 more closely. Due to the first through hole 1201, at least a portion of the internal space of the hemispherical structure is connected to the outside, and the air inside the hemispherical structure is discharged to the outside atmosphere, thereby reducing the closing resistance of the sealing element 1610 to the end cap 1200.

[0076] Specifically, in response to the elastic deformation of the seal 1610, the seal 1610 fits more tightly with the dust collection channel 1520, preventing the dust collected in the dust collection channel 1520 from overflowing. In addition, the venting action of the seal 1610 will also reduce the resistance to closing the end cover 120. Under the action of the reset member 1300, the end cover 1200 can more tightly seal the receiving space.

[0077] In some embodiments, when the sealing member 1610 seals the dust collection channel 1520 with a clearance fit, when the dust collection device 1000 performs negative pressure adsorption on the surface of the operating surface during operation, a negative pressure is created inside the first accommodating space 1101 and the second accommodating space 1102. This causes the sealing member 1610 to bulge towards the dust collection channel 1520 under air pressure. The elastic deformation of the sealing member 1610 ensures a good seal at the lower opening of the dust collection channel 1520. Thus, the end cap 1200 seals the first accommodating space 1101 and the second accommodating space 1102, while simultaneously isolating the first accommodating space 1101 from the second accommodating space 1102. A second aspect of the present disclosure provides a cleaning device 2000, including: the dust collection device 1000 provided in the first aspect of the present disclosure.

[0078] A third aspect of this disclosure provides a cleaning system, such as Figure 6 , Figure 7 As shown, it includes: a base station 3000; and a cleaning device 2000 provided in the second aspect of the present disclosure, wherein the base station 3000 is provided with a control mechanism, which is configured to switch the end cover 1200 of the dust collection device 1000 of the cleaning device 2000 from a closed position to an open position.

[0079] In some embodiments, a first control mechanism 3100 and a second control mechanism 3200 are provided inside the base station 3000. The first control mechanism 3100 is located inside the base station 3000 and is directly opposite the control switch 1400. In response to the cleaning device 2000 being assembled on the base station 3000, the first control mechanism 3100 is configured to switch the control switch 1400 of the cleaning device 2000 from a first control state to a second control state.

[0080] Specifically, such as Figure 8As shown, the base station 3000 has an internal receiving groove 3001 for accommodating the first control mechanism 3100. The first control mechanism 3100 includes a fixed rod 3110, a second elastic member 3120, and a slider 3130. The second elastic member 3120 is sleeved on the fixed rod 3110, and its two ends abut against the inner wall of the receiving groove 3001 and the slider 3130, respectively. In response to the second elastic member 3120 expanding under elastic action, at least a portion of the slider 3130 protrudes from the receiving groove 3001. The portion of the slider 3130 protruding from the receiving groove 3001 is the first button 3131. The first button 3131 is configured to apply a third-direction upward force to the dust collection device 1000 during the assembly of the dust collection device 1000 into the base station 3000, so that when the control switch 1400 is accessed via the first button 3131, it can switch from a first control state to a second control state under the pushing action of the first button 3131. In response to the first button 3131 acting on the power arm 1411 of the locking button 1410, the first elastic element 1420 is compressed. At this time, the control switch 1400 will switch from the first control state to the second control state. The end of the resistance arm 1412 away from the shaft 1413 tilts away from the housing 1100, thereby pushing the fastening end 1210 to release the engagement between the fastening end 1210 and the limiting part 1110.

[0081] In some embodiments, the second control mechanism 3200 is configured to cooperate with the end cover 1200 of the cleaning device 2000 to switch the end cover 1200 from a closed position to an open position. The base station 3000 has an internal space suitable for the movement of the pushing end 1220 of the end cover 1200. Specifically, the second control mechanism 3200 is disposed on the inner bottom wall of the installation space of the dust collection device 1000, and the second control mechanism 3200 is positioned directly opposite the pushing end 1220. In response to the dust collection device 1000 being assembled in the base station 3000, and the first control mechanism 3100 switching the control switch 1400 from a first control state to a second control state, the pushing end 1220 continuously moves downward, causing the second control mechanism 3200 to apply an upward force to the pushing end 1220 in a second direction. Due to the force of the second control mechanism 3200, the end cover 1200 switches from a closed position to an open position.

[0082] The dust collection device 1000, cleaning equipment 2000, and cleaning system provided in this disclosure are equipped with a control switch 1400. When the cleaning equipment 2000 with dust collection device is assembled with the base station 3000 of the cleaning system, the control mechanism inside the base station 3000 can switch the control switch 1400 from a first control state to a second control state, thereby further realizing the switching of the end cover 1200 from a closed position to an open position.

[0083] The dust collection device 1000, cleaning device 2000, and cleaning system provided in this disclosure, after the cleaning device 2000 completes dust collection on the operating surface, eliminate the need for the user to manually open the dust collection device 1000 during the dust removal process. Furthermore, there is no need to install complex closing force devices within the base station 3000. Simply placing the cleaning device 2000 inside the base station 3000 opens the end cover 1200 of the dust collection device 1000, achieving contactless dust disposal. The end cover 1200 automatically closes after the cleaning device 2000 leaves the base station 3000. The dust collection device provided in this disclosure has the advantages of simple structure, low manufacturing cost, and easy operation, which facilitates convenient operation and improves the user experience.
