Description

Technical Field

[0001] This invention relates to the field of vacuum cleaner technology, and in particular to a dust cup, a vacuum cleaner, and a cleaning component. Background Technology

[0002] Among existing dust removal products, vacuum cleaners are favored by people because of their good dust removal effect and convenient operation. There are many types of vacuum cleaners on the market, including canister, upright and handheld types. Regardless of the type of vacuum cleaner, they are all equipped with a dust cup to store the collected dust, hair and other dirt.

[0003] The most common dust cups on the market today consist of a ring-shaped cup body and a bottom cover. The bottom cover is installed on one end of the ring-shaped cup body by a snap-fit ​​mechanism. When the bottom cover is installed on the ring-shaped cup body, the bottom cover and the ring-shaped cup body work together to form a dust collection chamber. When the bottom cover is removed from the ring-shaped cup body, the dirt collected in the dust collection chamber can be emptied.

[0004] During the process of emptying the dust cup, it is impossible to guarantee that all the dirt inside the dust cup will be emptied. Some dirt will inevitably remain inside the dust cup. After emptying the dirt from the dust cup, the ring-shaped cup body needs to be manually grasped and the bottom cover installed. During this process, the dirt remaining in the dust cup will inevitably fall out from the bottom opening of the ring-shaped cup body under the influence of gravity, causing contamination. Therefore, those skilled in the art need to make improvements in this regard. Summary of the Invention

[0005] The main objective of this invention is to provide a dust cup that addresses the technical problem of dust cups in the prior art where dirt easily falls out during the process of closing the bottom cover.

[0006] To achieve the above objectives, the dust cup proposed in this invention includes a cup body and a cover body; wherein,

[0007] A dust storage chamber is formed inside the cup, and a dust extraction port is provided through the peripheral wall of the dust storage chamber;

[0008] The lid is movably disposed on the cup body, and the lid can move relative to the cup body to open or close the dust extraction port.

[0009] In one possible implementation, one end of the peripheral wall of the dust storage chamber is connected to the bottom wall of the dust storage chamber;

[0010] The dust extraction port extends to the periphery of the peripheral wall near the bottom wall.

[0011] In one possible implementation, the dust storage chamber is provided with a dust extraction channel, one end of which extends to the bottom of the dust storage chamber, and the other end of which is connected to the dust extraction port.

[0012] In one possible implementation, the dust cup includes a cover that covers the inner surface of a portion of the peripheral wall of the dust storage chamber and cooperates with the peripheral wall of the dust storage chamber to form the dust extraction channel.

[0013] In one possible implementation, the middle of the dust collection chamber is used to accommodate the cyclone separation structure of the vacuum cleaner;

[0014] The cover is designed with a concave arc shape on one side near the center of the dust storage chamber to avoid the cyclone separation structure.

[0015] In one possible implementation, the number of dust extraction ports is at least two, and the dust storage chamber is provided with at least two dust extraction channels, the number of dust extraction channels being the same as the number of dust extraction ports to correspond one-to-one.

[0016] Each of the dust extraction channels is connected to a corresponding dust extraction port, and the end of each dust extraction channel away from the corresponding dust extraction port extends to the bottom of the dust storage chamber.

[0017] In one possible implementation, the dust extraction channel extends in a spiral shape along the depth direction of the dust storage chamber;

[0018] The rotation direction of each of the dust extraction channels is the same.

[0019] In one possible implementation, the dust storage chamber has a dust inlet extending through its peripheral wall; the dust inlet is located on the side of the dust extraction port away from the bottom wall of the dust storage chamber.

[0020] In one possible implementation, the cover is rotatably disposed on the peripheral wall of the dust collection chamber. The cover is rotatable relative to the cup body and has an open state to open the dust extraction port and a closed state to close the dust extraction port. In the open state, the cover is located outside the dust extraction port. The cover can switch between the open state and the closed state under the drive of air pressure.

[0021] The present invention also proposes a vacuum cleaner, which includes a dust cup, the dust cup including a cup body and a cover body; a dust storage chamber is formed in the cup body, and a dust extraction port is provided through the peripheral wall of the dust storage chamber; the cover body is movably disposed on the cup body, and the cover body can move relative to the cup body to open or close the dust extraction port.

[0022] The present invention also proposes a cleaning component, which includes a base station and a vacuum cleaner. The vacuum cleaner includes a dust cup, which includes a cup body and a cover. A dust storage chamber is formed in the cup body, and a dust extraction port is provided through the peripheral wall of the dust storage chamber. The cover is movably disposed on the cup body and can move relative to the cup body to open or close the dust extraction port. The vacuum cleaner can be placed on the base station.

[0023] In one possible implementation, the base station includes a fan assembly, the base station forms a dust collection channel, the dust collection channel has a dust collection port that connects to the dust extraction port, the air inlet of the fan assembly is connected to the dust collection channel, and the fan assembly is used to drive the dirt in the dust storage chamber of the vacuum cleaner to move into the dust collection channel.

[0024] The dust cup of this invention has its dust extraction port located on the peripheral wall of the dust storage chamber. This ensures that when the dirt stored in the dust storage chamber is discharged from the dust extraction port, and the cover is closed to close the dust extraction port, the dust extraction port, not being located at the bottom of the cup, will not fall onto the dust extraction port on the peripheral wall of the cup, even if dirt remains inside the cup. In other words, the dirt remaining inside the cup will not fall outside, which helps ensure the hygiene of the dust cup and improves the user experience. Attached Figure Description

[0043] This invention proposes a dust cup 11.

[0044] In the embodiments of the present invention, please refer to Figures 5 to 8 The dust cup 11 includes a cup body 111 and a cover 112. A dust storage chamber 111a is formed inside the cup body 111, and a dust extraction port 111b is provided through the peripheral wall 111d of the dust storage chamber 111a. The cover 112 is movably disposed on the cup body 111, and the cover 112 can move relative to the cup body 111 to open or close the dust extraction port 111b.

[0045] The cup body 111 can be any shape, such as circular, near-circular, cylindrical, near-cylindrical, rectangular, near-rectangular, D-shaped, or other irregular shapes, without any specific limitation. Furthermore, the material of the cup body 111 is not limited in this embodiment of the invention; the material can be selected according to actual working conditions.

[0046] Specifically, the dust storage chamber 111a of the cup body 111 is used to store dirt (such as dust, hair, etc.), and the cup body 111 has a dust inlet 111c that communicates with the dust storage chamber 111a. Dirt enters the dust storage chamber 111a through the dust inlet 111c.

[0047] In some embodiments, the wall of the dust storage chamber 111a includes a peripheral wall 111d and a bottom wall 111e connected to one end of the peripheral wall 111d. In this embodiment, the dust inlet 111c can be disposed on the peripheral wall 111d or the bottom wall 111e. In other embodiments, the wall of the dust storage chamber 111a includes a peripheral wall 111d and a bottom wall 111e and a top wall respectively connected to the two ends opposite to the peripheral wall 111d. In this embodiment, the dust inlet 111c can be disposed on the peripheral wall 111d, the bottom wall 111e, or the top wall.

[0048] When the cup 111 is installed on the body 13 of the vacuum cleaner 1, the dust inlet 111c is aligned with and tightly connected to the suction channel 132 of the vacuum cleaner 1. The dirt sucked into the suction channel 132 enters the dust cup 11 through the dust inlet 111c.

[0049] The connection between the cup body 111 and the body 13 of the vacuum cleaner 1 is detachable. There are many ways to detach the cup body 111 and the body 13 of the vacuum cleaner 1, such as by attaching magnetic parts, by attaching Velcro, by snap-fit ​​structure, by fixing with screw threads, etc. Of course, multiple combinations of the above methods can also be used.

[0050] The vacuum cleaner 1 includes a cyclone separator 12. After the cup body 111 is installed on the body 13 of the vacuum cleaner 1, the cyclone separator 12 is located in the dust collection chamber 111a. The cyclone separator 12 is used to create a negative pressure in the dust collection chamber 111a, so that dirt can be moved from the suction channel 132 of the vacuum cleaner 1 into the dust collection chamber 111a by the airflow. Since the cyclone separator 12 is a common component of vacuum cleaners on the market, its operating principle and specific structure will not be described in detail here.

[0051] In some embodiments, the cup body 111 is composed of a peripheral wall 111d and a bottom wall 111e. The bottom wall 111e is disposed at one end of the peripheral wall 111d, and the peripheral wall 111d and the bottom wall 111e enclose a dust storage cavity 111a. An opening is formed at the end of the peripheral wall 111d away from the bottom wall 111e for the cyclone separation structure 12 to extend into the dust storage cavity 111a. In this embodiment, to ensure the installation stability of the cyclone separation structure 12, a portion of the cyclone separation structure 12 extends to and connects with the bottom wall 111e. For ease of description, the portion of the cyclone separation structure 12 that connects with the bottom wall 111e is defined here as the support structure 121.

[0052] Specifically, in order to ensure the stability of the connection between the support structure 121 and the bottom wall 111e, in some embodiments, the bottom wall 111e and the support structure 121 are provided with a positioning protrusion 115 and the other is provided with a positioning groove 121a. The support structure 121 is fixedly connected to the support structure 121 by engaging the positioning protrusion 115 with the positioning groove 121a.

[0053] Specifically, the outer surface of the positioning protrusion 115 is provided as a convex arc surface, which can avoid the generation of too many sharp edges on the outer surface of the positioning protrusion 115 and help reduce wear between it and the groove wall of the positioning groove 121a.

[0054] In some embodiments, the positioning protrusion 115 is disposed on the bottom wall 111e, and the positioning groove 121a is formed on the support structure 121. After the positioning protrusion 115 is inserted into the positioning groove 121a, there will inevitably be a gap between the positioning groove 121a and the positioning protrusion 115. This gap can easily cause dirt to enter the positioning groove 121a, thereby reducing the installation stability of the positioning protrusion 115 in the positioning groove 121a. Considering this, the present invention also provides a sealing ring 116 on the periphery of the positioning protrusion 115. The periphery of the groove opening of the positioning groove 121a abuts against the sealing ring 116. The sealing ring 116 can prevent dirt from entering the positioning groove 121a, which can effectively ensure the connection stability between the positioning protrusion 115 and the positioning groove 121a.

[0055] There are many ways to achieve the effect of opening or closing the dust extraction port 111b by moving the cover 112. For example, in some embodiments, the cover 112 can be installed on the peripheral wall 111d by a snap-fit ​​connection. By manually removing or installing the cover 112 on the peripheral wall 111d, the effect of opening or closing the dust extraction port 111b by the cover 112 can be achieved. In other embodiments, the cover 112 can be installed on the peripheral wall 111d by a rotatable connection. A torsion spring 117 is provided at the 1d connection point. This torsion spring 117 can drive the cover 112 to move to the position where the dust extraction port 111b is closed. During use, the cover 112 can be rotated manually or a negative pressure can be created outside the cover 112 to overcome the elastic force of the torsion spring 117 and rotate to the position where the dust extraction port 111b is open. In some embodiments, the cover 112 can open or close the dust extraction port 111b by sliding, and the movement of the cover 112 can be driven manually. Since there are many ways to move the cover 112 to open or close the dust extraction port 111b, they will not be listed one by one or specifically limited here.

[0056] It is understood that the dust cup 11 of the present invention, by setting the dust extraction port 111b on the peripheral wall 111d of the dust storage chamber 111a, ensures that when the dirt stored in the dust storage chamber 111a is discharged from the dust extraction port 111b, during the process of covering the dust extraction port 111b with the cover 112, since the dust extraction port 111b is not located at the bottom of the cup body 111, even if there is still dirt remaining in the cup body 111, it will not fall to the dust extraction port 111b on the peripheral wall 111d of the cup body 111. That is, the dirt remaining in the cup body 111 will not fall to the outside of the cup body 111. This helps to ensure the hygiene of the dust cup 11 and improve the user experience.

[0057] One end of the peripheral wall 111d of the dust storage chamber 111a is connected to the bottom wall 111e of the dust storage chamber 111a, and the dust extraction port 111b extends to the periphery of the peripheral wall 111d near the bottom wall 111e. In specific implementations, in some embodiments, the connection between the peripheral wall 111d and the bottom wall 111e can be a detachable connection. There are many ways to detach the peripheral wall 111d and the bottom wall 111e, such as by attaching magnetic components, by attaching Velcro, by using a snap-fit ​​structure, or by fixing with screws and threads. Of course, a combination of the above methods can also be used. In addition, in other embodiments, the connection between the peripheral wall 111d and the bottom wall 111e can also be an integral, non-detachable connection.

[0058] It is understandable that when dust, hair and other dirt are collected in the dust storage chamber 111a, the dirt will eventually fall onto the bottom wall 111e. Therefore, the dust extraction port 111b is set near the bottom wall 111e so that the dirt can quickly move to the dust extraction port 111b and then leave the dust storage chamber 111a through the dust extraction port 111b.

[0059] The dust storage chamber 111a is provided with a dust extraction channel 113. One end of the dust extraction channel 113 extends to the bottom of the dust storage chamber 111a, and the other end of the dust extraction channel 113 is connected to the dust extraction port 111b. It is easy to understand that without the dust extraction channel 113 to guide the flow of gas, when a negative pressure is formed outside the dust extraction port 111b, gas at any position in the dust storage chamber 111a can flow to the dust extraction port 111b. In reality, the dirt falls to the bottom of the dust storage chamber 111a. If the gas flows from the top of the dust storage chamber 111a to the dust extraction port 111b, it cannot effectively drive the dirt out of the dust extraction port 111b. Considering this, this embodiment sets up the dust extraction channel 113 to guide the flow of gas, so that the gas can only flow upward from the bottom of the dust storage chamber 111a to the dust extraction port 111b. In this way, the dirt at the bottom of the dust storage chamber 111a can be effectively driven out of the dust extraction port 111b, thereby improving the sewage discharge efficiency of the cup 111.

[0060] Please see Figure 6 During the process of draining the aforementioned cup 111, the dust inlet 111c acts as the air inlet, while the dust extraction port 111b acts as the air outlet. During the dust extraction process, the gas enters the dust storage chamber 111a from the dust inlet 111c, then flows to the bottom of the dust storage chamber 111a and enters the dust extraction channel 113, and then flows out from the dust extraction port 111b.

[0061] In the above embodiments, there are many ways to form the dust extraction channel 113. For example, in some embodiments, an air pipe can be set in the dust storage chamber 111a, and the pipe of the air pipe forms the dust extraction channel 113. In this embodiment, the air pipe is relatively easy to obtain and has the advantage of simple implementation. Specifically, the air pipe can be a stainless steel pipe, a metal pipe, a corrugated pipe, a rubber pipe, or a plastic pipe, etc., and no specific limitation is made here.

[0062] In other embodiments, a groove can be provided on the inner wall of the peripheral wall 111d of the cup body 111, and the dust extraction port 111b is provided on the groove wall. Then, a portion of the groove opening is sealed by a cover plate or other structure. In this way, the groove cavity forms a dust extraction channel 113. In this embodiment, the structure forming the dust extraction channel 113 can avoid occupying too much space in the dust storage cavity 111a, which is convenient for the installation of the cyclone separation structure 12 and beneficial for the miniaturization design of the cup body 111.

[0063] In the above-described embodiment of setting the groove, the groove is not limited to being set only on the inner wall surface of the peripheral wall 111d. The groove can also be set on the outer wall surface of the peripheral wall 111d. In this embodiment, the bottom wall 111e of the groove is provided with a through hole communicating with the dust storage chamber 111a. Dirt enters the groove through this through hole. The cover plate covers part of the groove opening from the outside of the cup body 111, and the other part of the groove opening not covered by the cover plate forms the dust extraction port 111b.

[0064] In some other embodiments, the dust cup 11 includes a cover 114, which covers the inner surface of the peripheral wall 111d of a portion of the dust storage chamber 111a and cooperates with the peripheral wall 111d of the dust storage chamber 111a to form a dust extraction channel 113. In this embodiment, the peripheral wall 111d covered by the cover 114 forms the wall of the dust extraction channel 113. This arrangement avoids placing too many covers 114 in the dust storage chamber 111a, which would affect the installation of the cyclone separation structure 12.

[0065] In the above-mentioned embodiment of the dust cup 11 including the cover 114, a groove can be provided on the inner wall surface of the peripheral wall 111d covered by the cover 114. In this way, while increasing the width of the dust extraction channel 113, it can also avoid occupying too much space of the dust storage chamber 111a, which is conducive to the rapid discharge of dirt from the cup 111.

[0066] During the installation of the cover 114, the connection between the cover 114 and the peripheral wall 111d can be a detachable connection or an integral non-detachable connection. There are many ways to detach the cover 114 and the peripheral wall 111d. Several implementation methods are listed below, but those skilled in the art should understand that the solution of this application is not limited to the following implementation methods.

[0067] In some embodiments, a groove can be provided on the inner wall surface of the peripheral wall 111d, and a part of the structure of the cover 114 can be inserted into the groove to achieve a fixed fit between the cover 114 and the peripheral wall 111d. In this way, in order to improve the connection stability between the cover 114 and the peripheral wall 111d and to prevent gas from flowing in the gap between the cover 114 and the peripheral wall 111d, after the cover 114 is inserted into the groove, sealant can be dripped into the groove or a flexible filler (such as sponge, rubber, silicone, etc.) can be added into the groove.

[0068] In other embodiments, threaded holes may be provided on the cover 114 and the peripheral wall 111d, and then screws or bolts may be passed through the threaded holes of the cover 114 and the peripheral wall 111d in sequence to fix the cover 114 to the peripheral wall 111d by screws or bolts.

[0069] In some other embodiments, a first magnetic part can be provided on the peripheral wall 111d, and a second magnetic attraction part can be provided on the cover 114. The cover 114 is fixed to the peripheral wall 111d by the magnetic connection between the first magnetic attraction part and the second magnetic attraction part. It should be understood that the first magnetic attraction part can be a part of the peripheral wall 111d itself (such as the peripheral wall 111d being made of magnetic material), or the first magnetic part can be a part of other components (such as a magnet) that are installed on the peripheral wall 111d. The formation method of the second magnetic attraction part can refer to the formation method of the first magnetic attraction part, and will not be described again here.

[0070] In the design of this application, in order to reduce the difficulty of dirt entering the dust extraction channel 113, preferably, the peripheral wall 111d of the end of the dust extraction channel 113 away from the dust extraction port 111b abuts against the bottom wall 111e of the cup body 111. By reducing the height difference between the opening of the dust extraction channel 113 away from the dust extraction port 111b and the bottom wall 111e, dirt can be easily and quickly flow into the dust extraction channel 113 with the gas.

[0071] It is much more difficult for dirt on the bottom wall 111e, which is far from the dust extraction channel 113, to enter the dust extraction channel 113 with the flow of gas than for dirt on the bottom wall 111e, which is close to the dust extraction channel 113. This is because the farther away from the dust extraction channel 113, the slower the gas flow speed becomes, and sometimes the slower the gas flow speed makes it difficult to move some heavier dirt. To address the aforementioned issues, in some embodiments, a dust collection groove is recessed in the bottom wall 111e, and the end of the dust extraction channel 113 furthest from the dust extraction port 111b is located within the dust collection groove. By setting the dust collection groove, a height difference exists at different positions on the inner wall surface of the bottom wall 111e. During the dust extraction process, the dirt in the dust collection groove is first extracted. Then, the dirt that did not originally fall into the dust collection groove can be moved to the vicinity of the dust collection groove by the gas and flow into the dust collection groove. Under the action of gravity and the movement of the gas, the dirt flowing into the dust collection groove can quickly approach the opening of the dust extraction channel 113 and finally enter the dust extraction channel 113. This helps to improve the efficiency of the cup body 111 in discharging dirt.

[0072] Of course, the design of this application is not limited to this. In some other embodiments, the inner wall surface of the bottom wall 111e can also be inclined downward in the height direction of the cup body 111, and the end of the dust extraction channel 113 away from the dust extraction port 111b is set close to the bottom of the bottom wall 111e. In this way, the dirt located at the lower position will be discharged from the cup body 111 through the dust extraction channel 113 first, and the dirt located at the higher position will flow to the lower position under the influence of gravity and gas, and then be discharged from the cup body 111 through the dust extraction channel 113. In this way, the sewage discharge efficiency of the cup body 111 can also be effectively improved.

[0073] The downward inclination of the inner wall surface of the bottom wall 111e can be either an inclination from one end of the inner wall surface to the other end, or an inclination from the periphery of the inner wall surface to the middle of the inner wall (including two implementations: the middle of the inner wall surface is high and the periphery of the inner wall surface is low, and the middle of the inner wall surface is low and the periphery of the inner wall surface is high).

[0074] When the bottom wall 111e is designed with a high center and a low periphery on the inner wall surface, combined with the embodiment of the cyclone separation structure 12 in the center of the bottom wall 111e described above, the high center of the inner wall surface can shorten the distance between it and the cyclone separation structure 12, so that the support structure 121 does not need to be too long, which is beneficial to save the material of the support structure 121.

[0075] Generally speaking, during the flow of gas in the dust extraction channel, energy loss occurs, causing the gas flow speed to gradually slow down. This is not conducive to the gas carrying dirt out of the dust extraction port 111b quickly. To solve the above problem, in some embodiments, the inner diameter of the dust extraction channel 113 gradually decreases along the direction close to the dust extraction port 111b. It is easy to understand that after the inner diameter of the dust extraction channel 113 decreases, the pressure on the gas increases. The increased pressure can increase the gas flow speed, thereby facilitating the rapid discharge of dirt from the dust extraction port 111b.

[0076] It should be noted that the design of this application is not limited to the above embodiments. In other embodiments, the inner diameter of a part of the dust extraction channel 113 may not be specifically limited, while the inner diameter of another part of the channel may gradually decrease.

[0077] The middle part of the dust collection chamber 111a is used to accommodate the cyclone separation structure 12 of the vacuum cleaner 1; the side of the cover 114 near the middle of the dust collection chamber 111a is arranged in a concave arc shape to avoid the cyclone separation structure 12. It should be explained that the phrase "the side of the cover 114 near the middle of the dust collection chamber 111a is arranged in a concave arc shape" should be interpreted broadly. That is, as long as the side of the cover 114 near the middle of the dust collection chamber 111a has a tendency to be concave, and this tendency to be concave can achieve the purpose of avoiding the cyclone separation structure 12, it can be considered that the side of the cover 114 near the middle of the dust collection chamber 111a is arranged in a concave arc shape. Since there are many specific ways in which this can be achieved, they will not be listed here.

[0078] It is understandable that if the cover 114 is connected to the cyclone separation structure 12, or if the cover 114 and the cyclone separation structure 12 are too close, hair is likely to fall at the point where the two are connected or in the gap between them, resulting in hair entanglement. This is not conducive to the cup 111 expelling hair. Therefore, without increasing the size of the cup 111, a concave arc shape is designed on the side of the cover 114 near the middle of the dust storage chamber 111a to solve the above problems.

[0079] The number of dust extraction ports 111b is at least two (two or more), and the dust storage chamber 111a is provided with at least two dust extraction channels 113. The number of dust extraction channels 113 is the same as the number of dust extraction ports 111b, corresponding one-to-one. Each dust extraction channel 113 is connected to its corresponding dust extraction port 111b, and the end of each dust extraction channel 113 away from its corresponding dust extraction port 111b extends to the bottom of the dust storage chamber 111a. It is easy to understand that by setting multiple dust extraction ports 111b to discharge dirt from inside the cup body 111, the dirt discharge efficiency of the cup body 111 can be improved.

[0080] In actual use, the amount of dirt stored inside the cup 111 can be adjusted to allow multiple (two or more) dust extraction ports 111b to work simultaneously. For example, when the dust storage chamber 111a is full of dirt, multiple dust extraction ports 111b can be used to discharge dirt simultaneously to increase the discharge efficiency of the cup 111. Or, when the amount of dirt stored in the dust storage chamber 111a is small, only one discharge port can be used to discharge dirt.

[0081] In the specific implementation process, the number of dust extraction ports 111b can be two, three, four or more. Correspondingly, when there are two dust extraction ports 111b, there are also two dust extraction channels 113, with one dust extraction channel 113 connected to one dust extraction port 111b. When there are three dust extraction ports 111b, there are also three dust extraction channels 113, and so on, without going into too much detail here.

[0082] Each dust extraction port 111b can be located at the same height of the peripheral wall 111d or at different heights of the peripheral wall 111d. There is no specific limitation on this. In some embodiments, each dust extraction port 111b can also be interconnected. There is no limitation on this either.

[0083] Specifically, each dust extraction port 111b is provided with a corresponding cover 112. Each cover 112 can open or close the corresponding dust extraction port 111b. When the vacuum cleaner 1 is vacuuming, each cover 112 closes the corresponding dust extraction port 111b.

[0084] The dust extraction channels 113 extend in a spiral shape along the depth direction of the dust storage chamber 111a; the spiral direction of each dust extraction channel 113 is the same. In specific implementation, the spiral direction of each dust extraction channel 113 can be either left-handed or right-handed, and there is no restriction on this.

[0085] Please see Figure 6 and Figure 7 When dust is drawn from the cup 111, the gas flows into the dust storage chamber 111a from the dust inlet 111c, then flows to the bottom of the dust storage chamber 111a and flows into the dust extraction channel 113 in the same direction of rotation as the dust extraction channel 113. Since the rotation direction of each dust extraction channel 113 is the same, the gas at different positions on the bottom wall 111e will flow into each dust extraction channel 113 in the same direction of rotation (such as clockwise or counterclockwise). The gas at different positions acts simultaneously, so that a rotating airflow can be formed in the dust storage chamber 111a, which drives the dirt in the dust storage chamber 111a to rotate and move. Finally, the dirt is discharged from the dust storage chamber 111a through the dust extraction channel 113 and the dust extraction port 111b. Under the drive of the rotating airflow, it is ensured that the dirt in the dust storage chamber 111a can be moved, and the movement speed of the dirt is also effectively guaranteed when it is discharged from the cup 111.

[0086] Considering that the dust cup 11 cannot be made too large, resulting in the inability to set too many dust extraction channels 113 in the dust storage chamber 111a, based on this, in many embodiments, preferably, the number of dust extraction ports 111b is two, and the number of dust extraction channels 113 is also two, with the two dust extraction ports 111b respectively located on opposite sides of the peripheral wall 111d.

[0087] Please see Figure 6 In some embodiments, a dust inlet 111c is provided through the peripheral wall 111d of the dust storage chamber 111a; the dust inlet 111c is located on the side of the dust extraction port 111b away from the bottom wall 111e of the dust storage chamber 111a. Specifically, in the height direction of the cup body 111, the position of the dust inlet 111c is higher than the height of the dust extraction port 111b.

[0088] It is easy to understand that if the height of the dust inlet 111c is lower than the height of the dust extraction port 111b, it proves that the dust inlet 111c is not sufficiently far away from the bottom wall 111e. When the vacuum cleaner 1 cleans the floor, carpet surface, tabletop, and other surfaces, dust enters the dust storage chamber 111a from the dust inlet 111c and then falls onto the bottom wall 111e. As the dirt on the bottom wall 111e gradually increases, the height of the dirt may exceed the height of the dust inlet 111c but not reach the height of the dust extraction port 111b. At this time, the dust storage chamber 111a is not full, and the dust inlet 111c is blocked by dirt, making it difficult for the dirt in the suction channel 132 to move into the dust storage chamber 111a, which is not conducive to the efficient use of the internal space of the cup body 111. During the dust extraction process, gas flows in from the dust inlet 111c and then flows to the bottom of the dust storage chamber 111a. In this process, the gas will carry the dirt attached to the peripheral wall 111d and the cyclone separation structure 12 to the bottom of the dust storage chamber 111a. If the position of the dust inlet 111c is too low, it will not be conducive to the gas effectively carrying the dirt on the peripheral wall 111d and the cyclone separation structure 12 to the bottom of the dust storage chamber 111a.

[0089] The cover 112 is rotatably disposed on the peripheral wall 111d of the dust collection chamber 111a. The cover 112 can rotate relative to the cup body 111 and has an open state (rotating to open the dust extraction port 111b) and a closed state (rotating to close the dust extraction port 111b). In the open state, the cover 112 is located outside the dust extraction port 111b. The cover 112 can switch between the open and closed states under the drive of air pressure. It is understood that using rotation to move the cover 112 to open or close the dust extraction port 111b has the advantage of simple implementation.

[0090] In this application, to achieve the technical effect of the cover 112 closing the dust extraction port 111b, in some embodiments, the cover 112 can be set as an arc-shaped plate larger than the dust extraction port 111b. The arc-shaped plate can fit against the outer surface of the peripheral wall 111d and cover the location of the dust extraction port 111b, thus closing the dust extraction port 111b. In other embodiments, the cover 112 can be set as a plate with the same shape as the dust extraction port 111b. The plate can be moved into the dust extraction port 111b, and the periphery of the plate is connected to the wall surface of the peripheral side of the dust extraction port 111b, thus closing the dust extraction port 111b. Since there are many ways to achieve the closing of the dust extraction port 111b by the cover 112, they are not listed one by one or specific limitations are made here.

[0091] There are many ways to make the cover 112 rotatably mounted on the peripheral wall 111d. For example, in some embodiments, the cover 112 can be rotatably mounted on the peripheral wall 111d by a torsion spring 117 and a matching structure. In other embodiments, a cylinder can be provided on the cover 112, and a post hole that mates with the cylinder can be provided on the peripheral wall 111d. The cover 112 rotates relative to the peripheral wall 111d by the rotation of the cylinder in the post hole. Since there are many ways to make the cover 112 rotatable relative to the peripheral wall 111d, they will not be listed or specifically limited here.

[0092] When the shape of the cover 112 is the same as the shape of the dust extraction port 111b, regardless of whether the cover 112 is rotated by the torsion spring 117 or by the fit between the cylinder and the cylindrical hole, in the design of this application, the cover 112 stops rotating when it just closes the dust extraction port 111b. The cover 112 cannot rotate into the dust extraction channel 113, thus preventing the dust extraction port 111b from being opened. This design is to prevent the dust extraction port 111b from being opened when the vacuum cleaner 1 is vacuuming (i.e., when a negative pressure is formed in the dust storage chamber 111a), allowing gas to flow into the dust storage chamber 111a through the dust extraction port 111b, thus preventing the vacuum cleaner 1 from vacuuming normally.

[0093] In order to restrict the cover 112 from moving into the dust extraction channel 113, in some embodiments, a limiting structure is provided in the dust extraction channel 113, which abuts against the cover 112 when the cover 112 is in the closed state to restrict the cover 112 from rotating into the dust extraction channel 113.

[0094] Specifically, the limiting structure can be a protrusion, a protrusion or a protrusion strip protruding from the inner wall of the dust extraction channel 113. The limiting structure can be arranged in a ring shape to restrict the cover 112 from moving into the dust extraction channel 113 in all directions around the circumference of the dust extraction channel 113.

[0095] The present invention also proposes a vacuum cleaner 1, please refer to [link / reference]. Figures 1 to 8 The vacuum cleaner 1 includes a body 13 and a dust cup 11. The specific structure of the dust cup 11 is as described in the above embodiments. Since the vacuum cleaner 1 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The body 13 forms a suction channel 132, and the dust cup 11 is detachably installed on the body 13. The dust inlet 111c of the dust cup 11 is connected to the suction channel 132.

[0096] The specific implementation method for how the dust cup 11 is detachably mounted on the body 13 has been listed above and will not be repeated here.

[0097] Vacuum cleaner 1 can be a handheld vacuum cleaner 1 or an automated vacuum cleaner 1; no specific restrictions are made here.

[0098] The vacuum cleaner 1 includes a cyclone separation structure 12. When the dust cup 11 is installed on the body 13, at least a part of the cyclone separation structure 12 extends into the dust storage chamber 111a of the dust cup 11. During the operation of the cyclone separation structure 12, a negative pressure is formed in the dust storage chamber 111a. At this time, the dust extraction port 111b is closed by the cover 112, and the gas can only flow into the dust storage chamber 111a from the dust inlet 111c and then be discharged outside the dust storage chamber 111a by the cyclone separation structure 12. One end of the suction channel 132 of the body 13 is connected to the dust inlet 111c, and the other end of the suction channel 132 can face the ground, carpet surface, or tabletop waiting to be cleaned. Dust, hair and other dirt in these waiting areas will enter the dust storage chamber 111a through the suction channel 113 and the dust inlet 111c under the suction of the suction channel 132.

[0099] The present invention also proposes a cleaning component, please refer to [link / reference]. Figures 9 to 11 The cleaning component includes a base station 2 and a vacuum cleaner 1. The specific structure of the vacuum cleaner 1 is as described in the above embodiments. Since this cleaning component adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The vacuum cleaner 1 can be placed on the base station 2.

[0100] In some embodiments, the base station 2 is capable of providing the vacuum cleaner 1 with at least one of the following services: charging or removing the dirt stored in the dust storage chamber 111a.

[0101] Specifically, the base station 2 includes a fan assembly 23 and a dust collection channel 21. The dust collection channel 21 has a dust collection port 22 that connects to the dust extraction port 111b. The air inlet of the fan assembly 23 is connected to the dust collection channel 21. The fan assembly 23 is used to drive the dirt in the dust storage chamber 111a of the vacuum cleaner 1 to move into the dust collection channel 21. It can be understood that when the user cleans with the vacuum cleaner 1, the vacuum cleaner 1 can be placed on the base station 2. After the fan assembly 23 is turned on, the dust collection channel 21 forms a negative pressure under the action of the fan assembly 23, which drives the cover 112 to rotate to the open position. Then, the dirt in the dust storage chamber 111a can be moved into the dust collection channel 21 through the dust extraction channel 113 and the dust extraction port 111b, automatically realizing the discharge of dirt from the dust cup 11.

[0102] To facilitate the cleaning of dirt in the later stage of base station 2, a dust bag 24 that is easy to replace can be set up and connected to the dust collection channel 21. After the dust bag 24 is full of dirt, the dust bag 24 can be taken out.

[0103] In specific implementation, the fan assembly 23 can be operated by an external power supply, or the fan assembly 23 can be operated by a battery 131 installed in the base station 2, thereby improving the independent operation capability of the base station 2. In addition, to facilitate the placement of the vacuum cleaner 1, the base station 2 also has a receiving compartment, in which the vacuum cleaner 1 is placed, the dust cup 11 is located inside the receiving compartment, and the dust collection port 22 is set on the wall around the receiving compartment.

[0104] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
