Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a cleaning equipment. Background Art

[0002] A common problem with most cleaning devices currently on the market (such as vacuum cleaners, floor scrubbers, and mops) is that the seal between the cup's air outlet and the exhaust vent in the main unit, which connects to the fan assembly, is achieved by attaching a sealing ring to one of the two components, then interfering with the other to create a seal. This arrangement makes it easy for the sealing ring's flange to flip during disassembly and assembly, resulting in a poor seal, reduced overall performance, and reduced cleaning ability. Summary of the Invention

[0003] Based on this, it is necessary to provide a cleaning device that improves the above defects in order to solve the problem in the prior art that the sealing ring between the cup body and the body is easily crushed, resulting in poor sealing between the cup body and the body, which in turn leads to a decrease in the performance of the entire machine and a decrease in cleaning ability.

The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0062] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0063] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. Throughout the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0064] In this application, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0065] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0066] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0067] The cleaning equipment can be a vacuum cleaner, a floor scrubber, a sweeper, a mop, a mite remover, etc., and can specifically be a household cleaning device and a commercial cleaning device. Generally, the cleaning equipment includes a fuselage, a power unit, a cup body, an action device (such as a floor brush, a suction nozzle, etc. that directly contacts the surface to be cleaned), etc. The action device is installed at the bottom of the fuselage, and the cup body and the power unit are both installed on the fuselage. The fuselage has a fuselage air duct connecting the cup body and the power unit. The part of the fuselage air duct connecting the cup body and the power unit is the exhaust air duct, and the part of the fuselage air duct connecting the action device and the inlet of the cup body is the intermediate air duct. A fan assembly is provided in the power unit. When the fan assembly is working, a negative pressure is generated inside it. The negative pressure is transmitted to the action device through the exhaust air duct, the cup body, and the intermediate air duct. The dirt on the surface to be cleaned is sucked away by the action device to achieve cleaning of the surface to be cleaned. The sucked-away dirt enters the cup through the central air duct, where it is filtered, and dust, sewage, and other dirt accumulate in the cup. The cup has an outlet duct, through which the gas flows through the exhaust duct of the machine body into the power unit, and finally is discharged to the outside. Of course, for modular cleaning equipment, the power unit can be detached from the machine body. When the power unit is connected to external components (such as a suction nozzle or a mite removal connector), a new cleaning device can be formed. The connection between the power unit and the external components must be airtight.

[0068] According to some embodiments of this application, please refer to Figure 1 、 Figure 2 and Figure 3The present application provides a cleaning device 100, comprising a first connector 110, a second connector 120, a sealing member 130 and an operating member 140. The first connector 110 comprises a first channel 111 having a first opening, the second connector 120 comprises a second channel 121 having a second opening, the second connector 120 is detachably assembled to the first connector 110, the first opening and the second opening are arranged opposite to each other and at least one of them serves as a receiving end S. One end of the sealing member 130 is sealed in the receiving end S, and the other end of the sealing member 130 is extended and retracted relative to the receiving end S along a first direction F1 under the control of the operating member 140. In the process of assembling the second connector 120 to the first connector 110, the other end of the sealing member 130 is controlled to extend away from the receiving end S to seal and connect the first channel and the second channel 121, and in the process of detaching the second connector 120 from the first connector 110, the other end of the sealing member 130 is controlled to retract toward the receiving end S.

[0069] During actual operation of the cleaning device 100, when the user assembles the second adapter 120 onto the first adapter 110, the actuator 140 controls the seal 130 to extend. During the extension process, the other end of the seal 130 extends away from the receiving end S and gradually approaches the other end of the first opening, the second opening, or another seal 130. When the second adapter 120 is in place, the other end of the seal 130 is sealedly connected to the first opening, the second opening, or the other end of the other seal 130, thereby sealing the first channel 111 and the second channel 121. When the user detaches the second adapter 120 from the first adapter 110, the actuator 140 controls the seal 130 to retract, causing the other end of the seal 130 to gradually retract toward the receiving end S. The other end of the seal 130 and the other end of the first opening, the second opening, or another seal 130 are separated from each other not only in the detachment direction, but also in the first direction F1. That is to say, the seal 130 in the above-mentioned cleaning device 100 is sealed and connected to the first opening, the second opening or the other end of another seal 130 only when it is assembled in place. When it begins to be disassembled or is not assembled in place, the other end of the seal 130 is in a free state and does not contact other end surfaces.

[0070] Compared with the prior art, the seal 130 is only sealed and connected to other end faces when the second connector 120 is assembled in place, and will not contact other end faces during the assembly or disassembly of the second connector 120. This can avoid the risk of the seal 130 being flanged during the assembly and disassembly of the second connector 120, thereby improving the sealing reliability of the cleaning equipment 100, as well as the performance and cleaning effect of the entire machine.

[0071] It should be noted that, in the later stage of the process of assembling the second connecting component 120 to the first connecting component 110, the other end of the sealing component 130 is controlled to extend away from the receiving end S to seal the first channel 111 and the second channel 121. In the early stage of the process of detaching the second connecting component 120 from the first connecting component 110, the other end of the sealing component 130 is controlled to retract toward the receiving end S. The state in which the relative position between the first connecting component 110 and the second connecting component 120 is in place is defined as the position-in-place state. In the position-in-place state, the relative position relationship between the first connecting component 110 and the second connecting component 120 is the same as the final assembly state, and whether the sealing component 130 is in place to seal the first channel 111 and the second channel 121 is not limited. The state in which the sealing component 130 is controlled to extend out of the receiving end S is defined as the extended state. The "process of assembling the second connecting component 120 on the first connecting component 110 (hereinafter referred to as the assembly process)" mentioned in the embodiment of the present application includes the above-mentioned in-position state and the above-mentioned extended state, and the in-position state and the extended state are both in the "late stage of the process" of the entire assembly process of the first connecting component 110 and the second connecting component 120.

[0072] At a later stage of the process of assembling the second connector 120 to the first connector 110, the other end of the seal 130 is controlled to extend away from the receiving end S, which includes two situations. The first situation is that the extended state of the seal 130 is after the first connector 110 and the second connector frame 120 are in the in-position state, that is, the seal 110 is controlled to extend and seal the first channel and the second channel after the first connector 110 and the second connector frame 120 are in the in-position state (an optional embodiment in this case is that the action member 140 is a motor, and after the first connector 110 and the second connector frame 120 are in the in-position state, the action member 140 is manually controlled via the control button to drive the seal 130 to extend out of the receiving end S and seal the first channel 111 and the second channel 121, and when the first connector 110 and the second connector 120 are detached, the action member 140 is manually controlled to drive the seal 130 to retract). The second situation is that the extended state of the seal 130 overlaps with the in-position state of the first connector 110 and the second connector 120, that is, in the process of the seal 130 extending, the first connector 110 and the second connector 120 gradually tend to be in position relative to each other, and when the relative positions of the two are in place, the seal 130 is fully extended and seals the first channel 111 and the second channel 121 (this can be achieved through the implementation method mentioned below). It can be understood that in the first situation, user operation is required, and the user must also make judgments or add additional structures to help the user judge whether the first connector 110 and the second connector 120 are in position, and the structure is complicated. Compared with the first situation, the second situation does not require human manipulation, and therefore does not require the addition of additional structures to help the user judge whether the first connector 110 and the second connector 120 are in position, and the structure is simpler.

[0073] The state in which the sealing component 130 is controlled to retract to the storage end S is defined as the retracted state. Similarly, the "process of detaching the second connecting component 120 from the first connecting component 110 (hereinafter referred to as the detachment process)" mentioned in the embodiment of the present application includes the above-mentioned in-position state and the above-mentioned retracted state, and both the in-position state and the retracted state are in the "early stage of the process" of the entire detachment process of the first connecting component 110 and the second connecting component 120. During detachment, the sealing component 110 can be in the retracted state first, and then the second connecting component 120 can leave the in-position state, or the sealing component 110 can be in the retracted state while the second connecting component 120 leaves the in-position state.

[0074] As for whether the sealing member 130 retracts to the receiving end S when the second connecting member 120 is not assembled with the first connecting member 110 or the two have been detached, there is no restriction. For example, after the second connecting member 120 is detached from the first connecting member 110, when the extension of the sealing member 130 does not affect the travel of the second connecting member 120, the sealing member 130 is controlled to extend to the receiving end S. When the first connecting member 120 needs to be assembled with the first connecting member 110, the extended sealing member 130 can be retracted to avoid squeezing the second connecting member 120. Then, when the assembly is about to be completed (that is, in the later stage of the above process), the sealing member 130 can be controlled to extend again.

[0075] In actual application, the "first connecting part 110" can be, but is not limited to, a body, a power unit, a cup, etc. The "first connecting part 110" can be a power unit connected to the body, a cup connected to the body, a nozzle connected to the power unit, a mite removal connector connected to the power unit, etc. Of course, the roles of the "first connecting part 110" and the "second connecting part 120" can be interchangeable.

[0076] It is understood that the receiving end S of the first channel 111 is electrically conductive to the first channel 111 itself, and the receiving end S of the second channel 121 is electrically conductive to the second channel 121 itself. The receiving end S extends along the conductive direction of the channel to which it belongs (the first channel 111 or the second channel 121) and is conductive in that conductive direction. When one end of the sealing member 130 is sealingly connected to the receiving end S, the sealing member 130 is electrically conductive to the channel to which the receiving end S belongs. The structures of the first channel 111 and the second channel 121 are not limited, that is, the structure and configuration of the receiving end S are not limited, as long as the sealing member 130 can seal the first channel 111 and the second channel 121.

[0077] The forms of the first channel 111 and the second channel 121 are not limited, as long as they can form a channel for air flow and form a receiving end S. Taking the first channel 111 as an example, the first channel 111 can be a channel constructed within the first adapter 110 itself. In this case, the receiving end S can be an open end of the channel within the first adapter 110. The first channel 111 can also be composed of a channel constructed within the first adapter 110 itself and a ring constructed outside the first adapter 110 and sealed and connected to the open end of the channel, with the internal structure of the ring forming the receiving end S.

[0078] Preferably, the first opening and / or the second opening serving as the receiving end S are respectively the enlarged ends of the first channel 111 and the second channel 121, and the diameter of the enlarged ends is larger than the diameter of the remaining channels of the first channel 111 and the second channel 121, so that after the sealing member 130 is sealed and installed, the diameter of the sealing member 130 is allowed to be consistent with the diameter of the remaining channels of the first channel 111 and the second channel 121, thereby avoiding reducing the wind resistance of the first channel 111 and the second channel 121.

[0079] Among them, "one end of the sealing member 130 is sealed and arranged at the receiving end S" means that the sealing member 130 is sealedly connected to the inner wall of the receiving end S to avoid air leakage at the connection between the sealing member 130 and the receiving end S. The method of achieving the sealed connection between the sealing member 130 and the receiving end S is not limited in the present application, for example, it can be bonding, snap-fitting, interference fitting, etc. In addition, the receiving end S can include one or two. In an optional embodiment, the receiving end S includes one, that is, the receiving end S is one of the first opening and the second opening. When the second fitting 120 is assembled in place, the other end of the sealing member 130 is sealed and connected to the other of the first opening and the second opening to seal the exhaust channel and the air outlet channel. In another optional embodiment, the receiving end S includes two, that is, the first opening and the second opening are both sealed and connected with the sealing member 130. At this time, when the second fitting 120 is assembled in place, the other ends of the two sealing members 130 cooperate and are sealed and connected to seal the first channel 111 and the second channel 121.

[0080] In some embodiments of this application, please refer to Figure 4 During the process of the second connecting member 120 being detached from the first connecting member 110 , the other end of the sealing member 130 is controlled to retract toward the receiving end S and is completely received in the receiving end S.

[0081] In actual operation, when the second connecting member 120 is completely detached from the first connecting member 110, the other end of the sealing member 130 is completely accommodated in the accommodation end S, that is, the sealing member 130 is entirely accommodated in the accommodation end S. In this way, when the second connecting member 120 is detached from the first connecting member 110, the accommodation end S can be used to protect the sealing member 130, which helps to increase the service life of the sealing member 130.

[0082] Of course, in other embodiments, the other end of the seal 130 may not be accommodated in the accommodation end S or may be partially accommodated in the accommodation end S, that is, the other end of the seal 130 may be located outside the accommodation end S. This application does not limit it, as long as the other end of the seal 130 is in a free state (not in contact with the end faces of other components) before the second adapter 120 is assembled into place or after it is disassembled.

[0083] The seal 130 has a sealing function. Optionally, the seal 130 is made of a soft sealing material such as nitrile rubber, fluororubber, polytetrafluoroethylene rubber, polyvinyl chloride plastic, etc. Optionally, the seal 130 is made of a hard sealing material such as copper alloy, chromium stainless steel, iron-based alloy, nickel-based alloy, etc. Of course, in a preferred embodiment, the seal 130 is made of a soft sealing material, which has better sealing performance, simple processing technology, and low cost. In a further embodiment, the seal 130 includes a telescopic portion and a sealing portion. The telescopic portion is connected to the action member 140. When it is extended and retracted under the action of the action member 140 and its own elastic force, it simultaneously controls the movement of the sealing portion. One end of the telescopic portion is connected to the receiving end S, and the sealing portion is connected to the other end of the telescopic portion and is used to seal the first channel 111 and the second channel 121. The sealing portion is preferably made of a soft sealing material. The telescopic portion is flexible and can be a telescopic sleeve or a bellows, etc., which is not specifically limited and its material is not limited. More preferably, the telescopic portion and the sealing portion are integrated into one body, which has better sealing performance. The telescopic portion can be a telescopic portion (a telescopic portion refers to a multi-stage telescopic portion formed by nesting multiple stages of telescopic tubes, where adjacent stages of telescopic tubes can move away from or toward each other). The telescopic portion can also be a spring, and the sealing portion can be a sealing ring fixed (e.g., bonded, clamped, etc.) to one end of the spring, and the other end of the spring is fixed to the receiving end S. The action member 140 acts on the spring to compress the sealing portion, and then extends under the elastic force of the spring itself. In order to ensure that the sealing member 130 is sealed and connected to the receiving end S, the sealing ring can be of a certain length and can always be sealed and connected to the receiving end S during expansion and contraction, or other methods can be used, which are not described in detail here.

[0084] In some embodiments of this application, please refer to Figure 3 and Figure 4 The sealing member 130 is an elastic expansion ring, one end of which is sealed and connected to the receiving end S. When the second fitting member 120 is assembled to the first fitting member 110, the other end of the elastic expansion ring tends to stretch away from the receiving end S.

[0085] During actual operation, when the second connector 120 is detached from the first connector 110, the action member 140 controls the elastic ring to expand and contract so that its other end retracts. During this process, the elastic ring is continuously compressed and accumulates elastic force. During the process of assembling the second connector 120 to the first connector 110, the action member 140 does not act on the elastic ring. The elastic ring recovers its extension under its own accumulated elasticity and tightly presses its other end against the first opening, the second opening, or the other end of the other sealing member 130. At this time, the elastic ring has a good sealing effect. At the same time, the elastic ring can keep the connection block 1421 described in this application connected to the action member 141, ensuring the stability of the motion transmission between the two.

[0086] Among them, the elastic expansion ring can be a bellows, such as a PVC (polyvinyl fluoride) bellows, or an expansion ring made of elastic materials such as silicone, rubber, etc., or an expansion ring composed of an expansion ring body and a spring sleeved and connected to the outside of the expansion ring body. The specific method is not limited.

[0087] In one embodiment, see Figure 7 , see also Figure 3 and Figure 4 The elastic expansion ring includes a corrugated section 131 and an assembly section 132. One end of the corrugated section 131 is sealed and connected to the receiving end S, and the other end of the corrugated section 131 is connected to one end of the assembly section 132. The other end of the assembly section 132 serves as the other end of the elastic expansion ring, and is used to seal and connect the first channel 111 and the second channel 121. Among them, the active member 140 (for example, the connecting ring 1422 described in this application) is connected to the outside of the assembly section 132 and is located at the bottom of the corrugated section 131. At this time, the assembly section 132 is connected to the active member 140, so that the active member 140 and the expansion ring can be reliably connected, and will not affect the expansion and contraction of the corrugated section 131 and can compress the corrugated section 131, thereby not affecting the expansion and contraction of the entire elastic expansion ring. Optionally, the assembly section 132 extends along the first direction F1 to form a straight section. At this time, the structure is simple and easy to manufacture. In some embodiments of the present application, please refer again to Figure 3 and Figure 4 The receiving end S has a sliding groove S1 that passes through its inner wall and outer wall. The acting member 140 includes an acting part 141 and a transmission part 142. Part of the transmission part 142 passes through the sliding groove S1 and is connected to the sealing member 130. The part of the transmission part 142 located outside the receiving end S is connected to the acting part 141. The acting part 141 controls the transmission part 142 to move along the sliding groove S1 in the first direction F1.

[0088] During actual operation, the action portion 141 applies a force to the transmission portion 142 to move in the first direction F1. When the transmission portion 142 moves, the portion of the seal 130 connected to the transmission portion 142 moves in the first direction F1, thereby achieving the expansion and contraction of the seal 130.

[0089] In some embodiments, the transmission portion 142 includes a connecting block 1421 and a connecting ring 1422. The connecting ring 1422 is located within the receiving end S and is sleeved onto the outer wall of the sealing member 130. The connecting block 1421 is protruded from the outer ring wall of the connecting ring 1422 and extends out of the sliding groove S1. The connecting block 1421 is in transmission connection with the operating portion 141.

[0090] At this time, the seal 130 is connected by the connecting ring 1422, and the connecting ring 1422 and the seal 130 achieve 360-degree contact. When the connecting block 1421 is moved along the first direction F1 by the action part 141, the connecting ring 1422 can lead the seal 130 to move as a whole, which helps to maintain the synchronization of expansion and contraction of various parts of the seal 130, especially for the corrugated seal 130, and thus helps to ensure the alignment accuracy and sealing reliability of the seal 130.

[0091] Further to the embodiment, please refer to 6, and refer to Figure 3 and Figure 4 The transmission part 142 further includes a guide block 1423 . The guide block 1423 and the connecting block 1421 are spaced apart and protruded from the outer wall of the connecting ring 1422 , and are movably arranged in the sliding groove S1 along the first direction F1 .

[0092] During actual operation, when the action part 141 controls the connecting block 1421 to move along the first direction F1, the guide block 1423 can only move along the first direction F1 under the restriction of the slide groove S1. In this way, the transmission part 142 can only move along the first direction F1 through the guide block 1423, that is, under the action of the transmission part 142, the seal 130 will only expand and contract along the first direction F1 and will not twist around the second direction F2. This ensures the alignment accuracy of the seal 130 and helps to ensure the sealing reliability.

[0093] Among them, the way to achieve "the guide block 1423 moves along the first direction F1 under the restriction of the slide groove S1" can be that the width of the guide block 1423 (perpendicular to the first direction F1) is equal to the width of the slide groove S1 (perpendicular to the first direction F1), or the inner wall of the slide groove S1 where the guide block 1423 is located in the first direction F1 has a guide groove, and the guide block 1423 moves along the guide groove. The specific method is not limited in this application as long as the guide block 1423 can be achieved as long as it can be achieved that the guide block 1423 moves only along the first direction F1.

[0094] Furthermore, at least the guide block 1423 in the transmission unit 142 is flexible. This facilitates the insertion of the guide block 1423 into the chute S1 during installation of the transmission unit 142. Alternatively, the entire transmission unit 142 may be flexible to facilitate integral fabrication. It is understood that the chute S1 not only guides the movement of the transmission unit 142 but also provides a secure mounting position for the transmission unit 142.

[0095] Of course, in other embodiments, the transmission portion 142 may be restricted to move only in the first direction F1 by limiting the range of motion of the connecting block 1421. For example, a guide post may be provided in the chute S1 where the connecting block 1421 is located, and the connecting block 1421 may have a guide hole through which the guide post passes, thereby guiding the connecting block 1421 to move only in the first direction F1. Alternatively, the width of the chute S1 where the connecting block 1421 is located may be the same as the width of the connecting block 1421.

[0096] Optionally, the guide block 1423 is supported on the slide groove S1 when the other end of the seal 130 seals the first channel 111 and the second channel 121. In actual operation, when the other end of the seal 130 is sealed and connected to the first channel 111 and the second channel 121, that is, when the second fitting 120 is assembled in place, the guide block 1423 is supported on the slide groove S1. At this time, since the seal 130 is cantilevered compared to the connecting block 1421, the slide groove S1 and the guide block 1423 are used to support the entire seal 130, further ensuring the docking accuracy and sealing reliability of the seal 130, while also avoiding the problem of easy wear of the seal 130 due to the excessive interference seal of the seal 130, and also helping to ensure the connection reliability of the connecting block 1421 and the action part.

[0097] Specifically, in one embodiment, the slide grooves S1 include multiple guide blocks 1423, which are spaced apart along the circumferential direction of the connecting ring 1422 and arranged on the outer wall of the connecting ring 1422. A slide groove S1 is formed in a one-to-one correspondence between the connecting block 1421 and all the guide blocks 1423.

[0098] At this time, one connecting block 1421 is correspondingly provided with one slide groove S1, and one guide block 1423 is correspondingly provided with one slide groove S1. By providing multiple guide blocks 1423, the telescopic ring can be uniformly extended and retracted in all directions and can be effectively supported, further ensuring alignment accuracy and sealing reliability.

[0099] In some embodiments of this application, please refer to Figure 3 and Figure 4 , refer to 8 together, the action portion 141 has a first mating surface M in contact with the transmission portion 142, and there is a height difference in the first direction. When the action portion 141 is controlled to move relative to the first adapter 110 in a second direction F2 intersecting with the first direction F1, the transmission portion 142 is driven by the height difference of the first mating surface M to control the other end of the sealing member 130 to expand and contract relative to the receiving end S in the first direction F1.

[0100] During actual operation, the transmission portion 142 (specifically, the connecting block 1421 in the transmission portion 142) abuts against the first mating surface M. Due to the height difference of the first mating surface M in the first direction, when the action portion 141 moves along the second direction F2, the transmission portion 142 moves along the first mating surface M. The action portion 141 is displaced relative to the transmission portion 142 in the second direction F2. Simultaneously, the transmission portion 142 is displaced relative to the action portion 141 in the first direction F1. This enables the transmission portion 142 to move in the first direction F1, causing the seal 130 to expand and contract in the first direction F1. In this way, the seal 130 expands and contracts as the action portion 141 moves along the second direction F2. The structure is simple and easy to implement.

[0101] Of course, in other embodiments, the operating portion 141 can also drive the transmission portion 142 to move in the first direction F1 when moving in the first direction F1, or the operating portion 141 can drive the transmission portion 142 to move in the first direction F1 when moving in other ways. This is not described in detail here. Furthermore, in other embodiments, to control the transmission portion 142 to move in the first direction F1 while the operating portion 141 moves in the second direction F2, the connection between the operating portion 141 and the sealing member 130 is not limited to the above-described embodiment. For example, a transmission mechanism such as a rack and pinion can be used. These mechanisms can be implemented by those skilled in the art using commonly available techniques and are not intended to be limiting or elaborated upon in this application.

[0102] In practical applications, the first direction F1 may be the direction of gravity. Specifically, in the embodiment, the first mating surface M is an inclined surface that is inclined downward along the extending direction of the sealing member 130 .

[0103] During actual operation, when the action portion 141 moves toward the seal 130 along the second direction F2, the transmission portion 142 moves upward, and the seal 130 retracts. When the action portion 141 moves away from the seal 130 along the second direction F2, the connection block 1421 moves downward, and the seal 130 extends. In this case, the first mating surface M is configured as an inclined surface to facilitate processing. Of course, in other embodiments, the first mating surface M can also be a downwardly inclined arc surface.

[0104] In a preferred embodiment, the transmission portion 142 has a second mating surface N facing the first mating surface M. The second mating surface N is an inclined surface that mates with the first mating surface M. In this case, the transmission portion 142 and the action portion 141 are connected via surface transmission, providing a reliable transmission method. Specifically, the connecting block 1421 has the aforementioned second mating surface N.

[0105] Of course, in other embodiments, the transmission part 142 and the action part 141 can also be connected to each other through point transmission, and the specific form is not repeated here.

[0106] In some embodiments, please refer again to Figure 3 and Figure 4 The action member 140 further includes an elastic member 143 . The elastic member 143 is disposed along the second direction F2 , and one end of the elastic member 143 is fixed to one of the first adapter 110 or the second adapter 120 , and the other end of the elastic member 143 is connected to the action portion 141 .

[0107] During actual operation, when the first connecting member 110 and the second connecting member are detached, the elastic member 143 controls the action portion 141 to move along the second direction F2 to a position where the sealing member 130 retracts under the action of its own restoring force, thereby keeping the sealing member 130 in a retracted state after the first connecting member 110 and the second connecting member are detached.

[0108] The elastic member 143 may be a spring, a spring sheet, an elastic rubber member or other structures, and is not particularly limited as long as it has elasticity in the second direction F2.

[0109] For details about the embodiments, please refer to Figure 3 and Figure 4 The other of the first connecting member 110 and the second connecting member 120 is provided with a pushing member 150. When the second connecting member 120 is assembled to the first connecting member 110, the pushing portion 141 of the pushing member 150 moves along the second direction F2.

[0110] During actual operation, when the pushing member 150 pushes the action part 141 to move along the second direction F2, the action part 141 compresses the elastic member 143. When the second connecting member 120 is detached from the first connecting member 110, the restoring force of the elastic member 143 itself acts on the action part 141 so that the action part 141 drives the other end of the sealing member 130 to retract, thereby realizing that the cleaning equipment 100 automatically retracts and contracts its own sealing member 130 without the need for external force (such as manpower).

[0111] The specific arrangement position of the pushing member 150 is not limited, as long as it can push the action part 141. In one example, the other of the first connecting member 110 and the second connecting member 120 is provided with a protruding pushing member 150 on the side facing each other. At this time, when the first connecting member 110 and the second connecting member 120 are assembled into one body, the pushing member 150 is not visible, which can improve the aesthetics of the cleaning equipment. Take the premise that "when the action part 141 moves along the second direction F2 toward the sealing member 130, the sealing member 130 retracts along the first direction F1, and when the action part 141 moves along the second direction F2 away from the sealing member 130, the sealing member 130 extends along the first direction F1" as an example for explanation. When the second connecting member 120 is assembled on the first connecting member 110, the elastic member 143 is in a compressed state. During the initial stages of the process of detaching the second connecting member 120 from the first connecting member 110, the pushing member 150 gradually withdraws along with the second connecting member 120 and its pressure on the actuating portion 141 gradually decreases. The elastic member 143 gradually deforms from its initial compressed state to its initial state, and the length of the elastic member 143 in the second direction F2 gradually increases. The actuating portion 141 gradually approaches the sealing member 130, and the sealing member 130 gradually retracts. When the pushing member 151 is completely detached from the actuating portion 141, the elastic member 143 returns to its initial state of maximum length, the actuating portion 141 is closest to the sealing member 130, and the sealing member 130 is in a retracted state. As the second connecting member 120 continues to detach from the first connecting member 110, friction between the sealing member 130 and other components is avoided, making it easier to remove the second connecting member 120.

[0112] In the later stage of the process of assembling the second connecting component 120 on the first connecting component 110, as the second connecting component 120 enters, the pushing member 150 and the acting portion 141 gradually approach each other, and then the pushing member 150 acts on the acting portion 141 and pushes the acting portion 141 to gradually move toward the elastic member 143 to compress the elastic member 143. During the compression process, the length of the elastic member 143 in the second direction F2 gradually decreases, so that the acting portion 141 gradually moves away from the sealing member 130, and then the sealing member 130 continues to stretch. When the second connecting component 120 is assembled in place, the sealing member 130 stretches into place to achieve a sealed connection.

[0113] The process of retraction or extension of the seal 130 occurs during the period of interaction between the pusher 151 and the action portion 141. That is, the retraction of the seal 130 occurs when the pusher 151 retreats and maintains contact with the action portion 141, causing the action portion 141 to move under the restoring force of the elastic member 143 (i.e., in the early stage of the disassembly process), and the extension of the seal 130 occurs when the pusher 151 pushes the action portion 141 to move and compresses the elastic member 143 (i.e., in the late stage of the assembly process). This ensures that the seal does not interfere with the movement of the second connector 120 in the early stage of the assembly process and the late stage of the disassembly process, thereby improving the convenience of assembly and disassembly of the second connector 120. At this time, when the second connector 120 is about to be installed on the first connector 110 or about to be removed from the first connector 110, the seal 130 is automatically retracted and extended, greatly simplifying the overall structure and control, reducing manufacturing costs, and using mechanical means to achieve sealing or unsealing of the seal 130, with high reliability.

[0114] In some embodiments, the second connecting member 120 is detachably assembled to the first connecting member 110 along a direction intersecting the first direction F1 .

[0115] At this point, relative displacement occurs between the pushing member 150 and the actuating portion 141 in the second direction F2. To enable the pushing member 150 to push the actuating portion 141 in the second direction F2, the actuating portion 141 and the pushing member 150 only need to abut against each other. This results in a relatively simple structure for both the pushing member 150 and the actuating portion 141. Furthermore, the cross-sectional configurations of the second connecting member 120 and the first connecting member 110 can be varied and are not limited to a single design. This allows for greater flexibility in the design of the outer shapes of the second connecting member 120 and the first connecting member 110.

[0116] Of course, in other embodiments, the second connecting member 120 can also be detachably assembled to the first connecting member 110 along the first direction F1. In this case, the pushing member 150 and the action portion 141 generate relative displacement in the first direction F1. In order to convert the force of the pushing member 150 in the first direction F1 into the force in the second direction F2 and push the action portion 141 to move along the second direction F2, an inclined surface can be used between the pushing member 150 and the action portion 141. Based on the principle similar to that of the first mating surface M and the second mating surface N mentioned above, when the pushing member 150 moves upward (the first direction F1 is the direction of gravity), the pushing member 150 moves upward along the upper inclined surface of the action portion 141 and pushes the action portion 141 to move leftward, thereby achieving compression of the elastic member 143. Optionally, in order to prevent the action portion 141 from pushing the member 150 upward, a baffle 122 is provided above the action portion 141 to limit the movement of the action portion 141 in the first direction F1.

[0117] In some embodiments, see Figure 8The action portion 141 includes a first block 1411 and a second block 1412 connected at an angle. The first block 1411 is connected between the elastic member 143 and the second block 1412 and can contact the pusher 150. The first mating surface M forms a side surface of the second block 1412 facing away from the first block 1411. An avoidance area 1413 is formed between the first block 1411 and the second block 1412.

[0118] In actual operation, when the second connecting member 120 is detachably mounted on the first connecting member 110 in a direction perpendicular to the first direction F1, the pushing member 150 may be displaced relative to the acting portion 141 in the first direction F1. In this case, a clearance area 1413 is formed between the first block 1411 and the second block 1412. The space in the clearance area 1413 in the first direction F1 allows the pushing member 150 to be displaced relative to the acting portion 141 without causing the acting portion 141 to move in the first direction F1. This prevents the acting portion 141 from obstructing the expansion and contraction of the sealing member 130, thereby ensuring sealing reliability.

[0119] Further, please refer again to Figure 8 A mounting post 1414 is provided on the side of the first block 1411 facing away from the first contact surface M. The elastic member 143 is sleeved onto the mounting post 1414. The mounting post 1414 facilitates guiding the elastic member 143 to extend along its elastic direction without skewing. The mounting post 1414 may be a cross post, a cylinder, or the like, without limitation.

[0120] In some embodiments, please refer again to Figure 3 and Figure 4 The first connecting member 110 and / or the second connecting member 120, to which the sealing member 130 is mounted, have a limiting groove C extending along the first direction F1. A portion of the action portion 141 is disposed within the first connecting member 110 and / or the second connecting member 120 and is connected to the transmission member 142 and the elastic member 143. Another portion of the action portion 141 extends out of the limiting groove C, configured to contact the pusher 150 and move along the limiting groove C in the second direction F2. At this point, the portion of the action portion 141 and the elastic member 143 are housed within the first connecting member 110 and / or the second connecting member 120, thereby protecting the action portion 140.

[0121] Specifically, the first block 1411 described above may partially extend out of the limiting groove C and contact the pushing member 150 .

[0122] In some embodiments of this application, please refer to Figure 3 and Figure 4One of the first opening and the second opening serves as the receiving end S, and the other is sealedly connected to a sealing tube 160 connected to itself. The end surface of the sealing tube 160 facing away from the first opening or the second opening connected thereto serves as a sealing surface 160a, and the sealing surface 160a is used to seal and mate with the other end of the sealing member 130.

[0123] At this time, the sealing of the first channel 111 and the second channel 121 is achieved by the sealing cooperation between the seal 130 and the sealing tube 160. The cross-sectional shape and sealing method of the sealing surface 160a of the seal 130 and the sealing tube 160 can be flexibly set, making the design more free and flexible.

[0124] Optionally, a concave-convex seal connection is adopted between the sealing surface 160a of the sealing tube 160 and the other end of the sealing member 130. Preferably, the sealing tube 160 is made of a soft sealing material with low manufacturing cost and good sealing reliability, for example, made of PVC (polyvinyl fluoride) material.

[0125] Specifically, in some embodiments, the second connector 120 is assembled to the first connector 110 along a third direction intersecting the first direction F1 and detached from the first connector 110 along a fourth direction opposite the third direction. The sealing surface 160a is a sealing slope that mates with the end face of the other end of the sealing member 130. The projection of the sealing slope on a plane parallel to both the first direction F1 and the third direction is a first projection. The side of the first projection pointing in the third direction is positioned closer to the corresponding opening end than the side of the first projection pointing in the fourth direction.

[0126] At this time, the second connecting component 120 can be detachably assembled to the first connecting component 110 along the sealing slope, which makes it convenient for users to take and place the second connecting component 120, saves labor, and helps to improve the overall aesthetics of the cleaning device 100.

[0127] In some embodiments, the first connecting part 110 is the fuselage, the second connecting part 120 is the cup body, the first channel 111 serves as the exhaust duct of the fuselage, and the second channel 121 serves as the outlet duct of the cup body. In this case, the cleaning device 100 includes at least the fuselage and the cup body, and may also include functional devices such as a floor brush and a suction nozzle. Combined with the sealing member 130 and the functional member 140 in the above embodiment, effective sealing of the fuselage and the cup body can be achieved. Furthermore, the cleaning device 100 also includes a power device and an functional device. The specific configuration of the power device and the functional device will not be described in detail here.

[0128] Specifically in the embodiment, the cup body is detachably assembled to the fuselage along a direction intersecting with the first direction F1. Combining the sealing member 130 and the action member 140 in the above embodiment, various types of designs of the assembly cross-section of the cup body and the fuselage can be realized.

[0129] Specifically for the embodiment, see Figure 9 、 Figure 10 and Figure 11 The cleaning device 100 is constructed with a receiving area K connected to the first channel 111 and a third channel 112 connected to the receiving area K. The bottom of the cup body also has a dirt inlet 125 that connects the inside and outside of the cup body, and the second channel is located at the top of the cup body. The cup body is removably assembled in the receiving area K. When assembled in the receiving area K, the dirt inlet 125 and the third channel 112 are connected in an interference seal, and the second channel 121 is sealed to the first channel 111 via a seal 130.

[0130] At this time, the dirt inlet 125 of the cup body is set at its bottom. The dirt inlet 125 and the third channel 112 should be sealed and connected. The third channel 112 is used to circulate the dirt sucked up by the working device. Avoid air leakage affecting the suction force of the cleaning equipment. Specifically, the third channel 112 and the dirt inlet 125 are both provided with sealing rings, and the receiving area K has an installation port for installing the cup body in and out. During actual assembly, the bottom part of the cup body located on the side of the installation port is first fitted with the bottom wall of the receiving area K (the third channel 112 runs through the bottom wall of the receiving area K), and the other parts are left hanging. Then, the cup body is rotated around the fitting portion so that the entire cup body gradually enters the receiving area K. During the continuous rotation, the dirt inlet 125 at the bottom of the cup body gradually approaches the outlet end of the third channel 112, and in the middle of the rotation, the dirt inlet 125 at the bottom of the cup body and the outlet end of the third channel 112 are first sealed and connected, while the seal 130 has not yet extended from the receiving end. The rotation continues, and the rotation force provided by the user continues to cause the dirt inlet 125 at the bottom of the cup body to be interference-fitted with the outlet end of the third channel 112, and the seal 130 is gradually controlled to extend until it is sealed and connected to the first channel 111 and the second channel 121 when it is rotated into place, thereby completing the assembly of the cup body.

[0131] As rotation continues, the interference fit between the dirt inlet 125 and the outlet of the third channel 112 generates a reaction force that prevents the cup from entering the receiving area K. If the first and second channels were also sealed using the interference fit method used in the prior art, the reaction force generated at both ends would seriously hinder the installation of the cup, making installation more difficult. In this embodiment, however, the seal 130 extends from the receiving end S only when the cup is nearly fully rotated. This reduces the resistance encountered during installation, significantly easing assembly difficulty and providing a better user experience.

[0132] Among them, the formation of the receiving area K can be defined by the fuselage itself, and can be defined by the fuselage or other structures together. For example, it can be defined by an intermediate structure arranged on the fuselage and the fuselage together. The intermediate structure has a third channel 112 connecting the action device and the cup body, which is not specifically limited in this application.

[0133] Further to the examples, please refer to Figure 5 , see also Figure 2 The cup body also includes a main body and a separation assembly disposed within the main body. The air outlet duct is disposed within the main body. The separation assembly includes an air inlet duct 123 and a baffle 122. The lower end of the air inlet duct 123 extends through the main body and is configured to form a dirt inlet 125 for communication with the operating device. The upper end of the air inlet duct 123 is located within the baffle 122. The second channel 121 includes a filter portion 124 that connects the interior and exterior of the second channel 121. During operation, dirt from the operating device enters the baffle 122 through the dirt inlet 125 and the air inlet duct 123. At this time, the solid and liquid components of the dirt, blocked by the baffle 122, descend along the inner wall of the baffle 122 and accumulate within the main body. The gaseous component flows out of the baffle 122, is filtered by the filter portion 124, and then enters the second channel 121. Finally, it enters the first channel 111 through the seal 130. Optionally, the baffle 122 is hemispherical or bowl-shaped. The filter portion 124 may be a filter mesh or other filter components.

[0134] Compared with the prior art, the above-mentioned cleaning device 100 has a sealing connection between the seal 130 and other end faces only when it is assembled in place, and will not contact other end faces during the assembly or disassembly of the second connecting part 120, thereby avoiding the risk of the seal 130 being flanged, thereby improving the sealing reliability of the cleaning device 100, as well as the performance and cleaning effect of the entire machine.

[0135] According to some embodiments of the present application, the present application further provides a cleaning device 100, comprising the first connector 110, the sealing member 130 and the action member 140 in the above-mentioned embodiment, wherein the first connector 110 has a receiving end S, and the seal is arranged in the receiving end S, and the action member 140 includes an action portion 141 and a transmission portion 142; the action portion 141 is arranged on the first connector 110, and its surface facing the transmission portion 142 has a first mating surface M; the transmission portion 142 is in contact with the first mating surface M and is connected to the seal 130. There is a height difference in the first direction F1 on the first mating surface M. Driven by the height difference, the transmission portion 142 controls the seal 130 to expand and contract in the first direction F1 relative to the receiving end S.

[0136] During actual operation of the cleaning device 100, the transmission portion 142 abuts against the first mating surface M. Due to the height difference of the first mating surface M in the first direction, as the action portion 141 moves in the second direction F2, the transmission portion 142 moves along the first mating surface M. The action portion 141 is displaced relative to the transmission portion 142 in the second direction F2. Simultaneously, the transmission portion 142 is displaced relative to the action portion 141 in the first direction F1. This movement of the transmission portion 142 in the first direction F1 causes the sealing member 130 to expand and contract in the first direction F1. In this manner, the sealing member 130 expands and contracts as the action portion 141 moves in the second direction F2.

[0137] The following describes the assembly process of the first connector 110 and the second connector 120 in the above embodiment as an example. When the user assembles the second connector 120 onto the first connector 110, the actuator 140 allows the transmission portion 142 to move downward via the first mating surface M, causing the seal 130 to extend. During the extension process, the other end of the seal 130 extends away from the receiving end S and gradually approaches the second opening of the second channel 121 of the second connector 120. When the second connector 120 is fully assembled, the transmission portion 142 moves downward, and the seal 130 also extends. The other end of the seal 130 is sealedly connected to the second opening of the second connector 120, thereby sealing the first channel 111 on the first connector 110 and the second channel 121 on the second connector 120. When the user removes the second connecting member 120 from the first connecting member 110, the actuator 140 controls the upward movement of the transmission portion 142 via the first mating surface M, thereby controlling the contraction of the seal 130. This causes the other end of the seal 130 to gradually retract toward the receiving end S. The other end of the seal 130 and the second opening of the second connecting member 120 are separated from each other not only in the removal direction but also in the first direction F1. In other words, in the cleaning device 100, the seal 130 is sealedly connected to the second opening of the second connecting member 120 only when fully assembled. When the seal 130 is being removed or is not fully assembled, the other end of the seal 130 is free and does not contact the other end surface.

[0138] Compared with the prior art, the seal 130 is only sealed and connected to other end faces when the second connector 120 is assembled in place, and will not contact other end faces during the assembly or disassembly of the second connector 120. This can avoid the risk of the seal 130 being flanged during the assembly and disassembly of the second connector 120, thereby improving the sealing reliability of the cleaning equipment 100, as well as the performance and cleaning effect of the entire machine.

[0139] The first connecting member 110, the sealing member 130, and the active member 140 in the embodiments of the present application include the features of the first connecting member 110, the sealing member 130, and the active member 140 in any of the above embodiments, which are not described in detail here. Further to the embodiment, the cleaning device 100 also includes the second connecting member 120 mentioned in the above embodiments, as well as other features of the cleaning device 100 in the above embodiments, which are not described in detail here.

[0140] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0141] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
