Description
TECHNICAL FIELD
[0001] The utility model relates to a cleaning equipment technical field, concretely relates to a sealing device of dust collection channel of cleaning equipment. BACKGROUND
[0002] In the cleaning process of the self-moving robot, garbage (such as dust, debris, hair, etc.) is collected into the dust box of the self-moving robot, and when the self-moving robot returns to the base station after completing the cleaning task, the base station can collect the garbage in the dust box of the self-moving robot into the dust bag of the base station. Specifically, the dust outlet of the dust box is communicated to the dust outlet cavity of the self-moving robot, and when the self-moving robot returns to the base station, the outlet of the dust outlet cavity can be docked with the dust suction port of the base station, and the dust suction port is communicated to the dust bag through the air duct. When the base station performs dust collection operation on the self-moving robot, the fan is started to generate negative pressure, so that the garbage in the dust box of the self-moving robot enters the dust bag through the dust outlet cavity and the dust suction port.
[0003] However, during the dust collection operation of the base station, the outlet of the dust outlet cavity and the dust suction port of the base station are prone to gaps, so that external garbage such as sewage and the like, especially some self-moving robots are also provided with wet cleaning elements such as rollers, rags and the like, and the cleaning elements usually have residual liquid after cleaning. The residual liquid is easy to enter the dust bag through the gap between the outlet of the dust outlet cavity and the dust suction port during dust collection, so that the dust bag is wetted, and after a long time, the dust bag produces an odor, resulting in the need to replace the dust bag more frequently. Therefore, it is particularly important to maintain the sealing property of the outlet of the dust outlet cavity and the dust suction port during the dust collection operation of the base station.
[0004] The existing cleaning equipment is usually provided with a sealing element, which seals and connects the outlet of the dust outlet cavity and the dust suction port during the dust collection operation of the base station, but the sealing connection between the outlet of the dust outlet cavity and the dust suction port is basically achieved by the abutment of the self-moving robot and the base station to make the sealing element and the outlet of the dust outlet cavity or the dust suction port interference connection. The sealing property of this connection is poor, especially during the dust collection process of the base station, the negative pressure in the air duct further makes this sealing connection easy to fail.

[0032] Cleaning equipment, such as reference Figure 1 As shown, the system may include a base station 1 and a self-moving robot 2. The self-moving robot 2 may be a cleaning tool such as a robotic vacuum cleaner. The self-moving robot 2 typically has a dustbin 201. When performing a cleaning task, the self-moving robot 2 collects and stores the collected debris in the dustbin 201. An exhaust vent baffle 2011 is located at the outlet of the dustbin 201. When the cleaning equipment is not in dust collection mode, the exhaust vent baffle 2011 is closed, preventing debris from being discharged from the dustbin 201 outlet, and the debris is collected in the dustbin 201. The base station 1 can be used to collect the debris in the dustbin 201, preventing debris from filling the dustbin 201 and causing the self-moving robot 2 to be unable to perform its cleaning operation normally. Specifically, base station 1 is equipped with a dust bag, a base station air duct, and a dust suction port 109. The dust suction port 109 is connected to the dust bag through the base station air duct. After the self-propelled robot 2 docks with base station 1, the dust suction port 109 can dock with the dust discharge port 2021 of the dust outlet chamber 202 of the self-propelled robot 2. At this time, the dust discharge port 2021, the dust suction port 109, and the base station air duct form a dust collection channel. Base station 1 is also equipped with a fan. After the fan is started, a negative pressure is formed in the dust collection channel, causing the exhaust port baffle 2011 to be in the open state. The dust collection channel is connected, and the garbage in the dust box 201 is discharged into the dust bag of base station 1 for collection under the action of negative pressure.
[0033] At present, the existing cleaning equipment generally sets a sealing element between the dust suction port 109 and the dust discharge port 2021, and uses the abutment of the self-moving robot 2 and the base station 1 to make the sealing element in interference connection with the dust suction port 109 or the dust discharge port 2021, so as to seal the communication between the dust suction port 109 and the dust discharge port 2021. However, the sealing effect of the sealing connection achieved only by the abutment of the self-moving robot 2 and the base station 1 cannot be guaranteed, and during the dust collection operation, the problem of external garbage entering the dust bag may still occur.
[0034] The utility model provides a kind of sealing device of cleaning equipment dust collection channel for the poor sealing effect of existing cleaning equipment dust collection channel, and referring to Figures 1-5 As shown, the sealing device includes: first sealing component 102, moving assembly 104 and second sealing component 103 connected in sequence, respectively, first sealing component 102 can be used to fit with the inner wall of the dust discharge port 2021 of the self-moving robot 2, and second sealing component 103 can be used to fit with the inner wall of the dust suction port 109 of the base station 1. First sealing component 102, moving assembly 104 and second sealing component 103 are hollow, and first sealing component 102, moving assembly 104 and second sealing component 103 form a part of dust collection channel in sealed communication, so that the garbage in the self-moving robot 2 can enter the dust bag of the base station through the dust discharge port 2021, first sealing component 102, moving assembly 104, second sealing component 103 and dust suction port 109, respectively.
[0035] The sealing device provided by the utility model further includes a driving assembly for driving the axial movement of the moving assembly 104. It should be noted that the axial movement of the moving assembly 104 refers to the reciprocating movement of the moving assembly along the central axis direction of the above-mentioned part of the integrated channel, for example, referring to Figure 1 As shown, the axial movement of the moving assembly 104 refers to the reciprocating movement along the central axis direction of the part of the integrated channel. Figure 1The first sealing part 102, the moving assembly 104 and the second sealing part 103 constitute a dust collection channel. The first sealing part 102 can be in sealed communication with the dust outlet 2021 of the self-moving robot, and the second sealing part 103 can be in sealed communication with the dust inlet 109 of the base station 1. Thus, the dust outlet 2021 and the dust inlet 109 are in sealed communication through the sealing device, and the dust collection channel is formed by the dust outlet 2021, the first sealing part 102, the moving assembly 104, the second sealing part 103, the dust inlet 109 and the air duct of the base station. The garbage in the dust box 201 is collected in the dust bag through the dust collection channel. Further, compared with the existing sealing device, when the self-moving robot 2 and the base station 1 are docked for dust collection, the driving assembly provides active driving force to the moving assembly 104, and the active driving force acts on the first sealing part 102 to make the first sealing part 102 in sealed communication with the dust outlet 2021, or the active driving force acts on the second sealing part 103 to make the second sealing part 103 in sealed communication with the dust inlet. Thus, the sealing device provided by the utility model realizes the sealed communication between the dust outlet 2021 of the self-moving robot 2 and the dust inlet 109 of the base station 1, and can improve the sealing effect and stability of the sealing device, greatly prevent external substances such as dust, moisture, hair and debris from entering the dust collection channel during dust collection, and then reaching the dust bag. Especially, when the self-moving robot 2 is a sweeping robot with a wet cleaning element such as a roller, the sealing device provided by the utility model can prevent the residual liquid (such as moisture and sewage) on the wet cleaning element such as the roller from entering the dust bag through the dust collection channel, avoid the dust bag from easily producing odor, and reduce the frequency of replacing the dust bag.
[0036] Thus, through the sealing device provided by the utility model, the first sealing part 102, the moving assembly 104 and the second sealing part 103 constitute a dust collection channel, the first sealing part 102 can be in sealed communication with the dust outlet 2021 of the self-moving robot, and the second sealing part 103 can be in sealed communication with the dust inlet 109 of the base station 1. Thus, the dust outlet 2021 and the dust inlet 109 are in sealed communication through the sealing device, and the dust collection channel is formed by the dust outlet 2021, the first sealing part 102, the moving assembly 104, the second sealing part 103, the dust inlet 109 and the air duct of the base station. The garbage in the dust box 201 is collected in the dust bag through the dust collection channel. Further, compared with the existing sealing device, when the self-moving robot 2 and the base station 1 are docked for dust collection, the driving assembly provides active driving force to the moving assembly 104, and the active driving force acts on the first sealing part 102 to make the first sealing part 102 in sealed communication with the dust outlet 2021, or the active driving force acts on the second sealing part 103 to make the second sealing part 103 in sealed communication with the dust inlet. Thus, the sealing device provided by the utility model realizes the sealed communication between the dust outlet 2021 of the self-moving robot 2 and the dust inlet 109 of the base station 1, and can improve the sealing effect and stability of the sealing device, greatly prevent external substances such as dust, moisture, hair and debris from entering the dust collection channel during dust collection, and then reaching the dust bag. Especially, when the self-moving robot 2 is a sweeping robot with a wet cleaning element such as a roller, the sealing device provided by the utility model can prevent the residual liquid (such as moisture and sewage) on the wet cleaning element such as the roller from entering the dust bag through the dust collection channel, avoid the dust bag from easily producing odor, and reduce the frequency of replacing the dust bag.
[0037] In some embodiments, the sealing device as described above can be arranged in the self-moving robot 2 or in the base station 1. Referring to Figure 1 The sealing device is arranged in the base station 1, and the moving assembly 104 drives the first sealing component 102 upward to fit the first sealing component 102 with the inner wall of the dust discharge port 2021, thereby sealingly connecting the first sealing component 102 with the dust discharge port 2021. Alternatively, the sealing device can be arranged in the self-moving robot 2, which is substantially in mirror image with the sealing device shown in Figure 1 The moving assembly 104 drives the second sealing component 103 downward to fit the second sealing component 103 with the inner wall of the dust suction port 109, thereby sealingly connecting the second sealing component 103 with the dust suction port 109.
[0038] Specifically, according to one embodiment of the sealing device provided by the present application, the sealing device is arranged in the self-moving robot 2, the driving assembly, the first sealing component 102, the moving assembly 104 and the second sealing component 103 are arranged in the self-moving robot 2, the first sealing component 102 is fixedly connected with the dust discharge port 2021, and when the base station 1 performs dust collection, the driving assembly drives the moving assembly 104 to move the second sealing component 103 toward the dust suction port 109 and achieve sealing connection with the dust suction port 109. However, the internal installation space of the self-moving robot 2 is limited, so according to the preferred embodiment of the sealing device provided by the present application, the sealing device is installed in the base station 1, specifically, the driving assembly, the first sealing component 102, the moving assembly 104 and the second sealing component 103 are arranged in the base station base 101 of the base station 1, and the second sealing component 103 is fixedly connected with the dust suction port 109. When the base station 1 performs dust collection, the driving assembly drives the moving assembly 104 to move axially, and drives the first sealing component 102 to move toward the dust discharge port 2021 and fit with the inner wall of the dust discharge port 2021.
[0039] Through the above preferred embodiment, the second sealing component is fixedly connected with the dust suction port 109, which ensures the sealing of the second sealing component 103 and the dust suction port 109. The driving assembly drives the moving assembly 104 to move axially, and drives the first sealing component 102 to fit with the inner wall of the dust discharge port 2021, which realizes the sealing connection of the first sealing component 102 and the dust discharge port 2021 by the driving force of the driving assembly, and also ensures the sealing of the first sealing component 102 and the dust discharge port 2021, thereby ensuring the sealing of the sealing device of the present application to sealingly connect the dust discharge port 2021 with the dust suction port 109. At the same time, the sealing device is installed in the base station 1, which can facilitate the installation of the sealing device and ensure the internal installation space of the self-moving robot 2.
[0040] In some embodiments, referring to Figures 3-5As shown, the moving assembly 104 can include a support skeleton 1041 and a second moving component arranged on the side of the support skeleton 1041, the support skeleton 1041 is sealedly communicated between the first sealing component 102 and the second sealing component 103, the second moving component can drive the support skeleton 1041 to move axially, the axial movement of the support skeleton 1041 drives the first sealing component 102 to move axially, so that the first sealing component 102 is attached to the inner wall of the dust outlet 2021, and the sealed communication between the first sealing component 102 and the dust outlet 2021 is realized.
[0041] The shapes of the first sealing component 102 and the second sealing component 103 can be any shape as long as they are attached to the inner walls of the dust outlet 2021 and the dust suction port 109 respectively to realize sealed communication. In some embodiments, the dust outlet 2021 and the dust suction port 109 are square, and the first sealing component 102 and the second sealing component 103 are combined Figure 4 and Figure 5 As shown, the first sealing component 102, the support skeleton 1041, and the second sealing component 103 are in the shape of a square box, so that the first sealing component 102 and the second sealing component 103 are attached to the inner walls of the dust outlet 2021 and the dust suction port 109 respectively. The top end and the bottom end of the support skeleton 1041 extend into the first sealing component 102 and the second sealing component 103 respectively and are attached to the inner walls of the first sealing component 102 and the second sealing component 103, so that the first sealing component 102, the support skeleton 1041, and the second sealing component 103 are in sealed communication.
[0042] In some embodiments, first and second flanges for abutting the top end and the bottom end of the support skeleton 1041 are respectively formed on the inner walls of the first sealing component 102 and the second sealing component 103. In the dust collection working state and the non-dust collection working state of the base station 1, the first flange always abuts the top end of the support skeleton 1041. In the non-dust collection working state of the base station 1, the second flange abuts the bottom end of the support skeleton 1041, so that the support skeleton 1041 is communicated between the first sealing component 102 and the second sealing component 103. In the dust collection working state of the base station 1, as the driving assembly drives the support skeleton 1041 to move towards the dust outlet 2021, the bottom end of the support skeleton 1041 gradually moves away from the second flange. When at least part of the first sealing component 102 moves into the dust outlet 2021, the bottom end of the support skeleton 1041 is still in the second sealing component 103, so as to ensure that the first sealing component 102, the support skeleton 1041, and the second sealing component 103 can always maintain a state of sealed communication during the axial movement of the support skeleton 1041.
[0043] In some embodiments, the driving assembly drives the second moving assembly to move axially, thereby driving the support framework 1041 and the first sealing component 102 to move axially. For example, the driving assembly can include, but is not limited to, an electric motor, a hydraulic machine, a pneumatic machine, etc. The second moving assembly can include a telescopic rod and a connecting rod, the two ends of the connecting rod being connected with the telescopic rod and the outer wall of the support framework 1041 respectively. The driving assembly drives the telescopic rod to extend or retract, thereby driving the support framework 1041 to move axially.
[0044] Alternatively, according to one embodiment of the sealing device of the present application, as shown in Figure 2 and Figure 3 , the driving assembly can include a driving component 107 and a first moving component in transmission connection with the driving component 107. The first moving component includes a first sliding block 108, and the first sliding block 108 has a first inclined surface 1081. The second moving component includes a second sliding block 1042, and the second sliding block 1042 has a second inclined surface 1045 matched with the first inclined surface 1081. The driving component 107 is configured to drive the first sliding block 108 to move towards the second sliding block 1042 and abut against the second sliding block 1042, so that the second sliding block 1042 moves towards the dust discharging port 2021 together with the first sealing component 102. Specifically, as shown in Figure 3 and Figure 5 , the first sliding block 108 and the second sliding block 1042 are formed with the first inclined surface 1081 and the second inclined surface 1045 matched with each other. In the direction away from the second sliding block 1042, the first inclined surface 1081 gradually rises. Therefore, when the driving component 107 continuously drives the first sliding block 108 to move towards the second sliding block 1042, the second sliding block 1042 gradually rises under the cooperation of the first inclined surface 1081 and the second inclined surface 1045. That is, when the first inclined surface 1081 starts to contact the second inclined surface 1045, the first sliding block 108 continues to move towards the second sliding block 1042. In this process, it is equivalent to that the second sliding block 1042 continuously climbs along the first inclined surface 1081, so as to realize the rising of the second sliding block 1042, drive the first sealing component 102 to move towards the dust discharging port 2021, and make at least part of the first sealing component 102 enter the dust discharging port 2021 and abut against the inner wall of the dust discharging port 2021, so as to realize the sealed communication between the first sealing component 102 and the dust discharging port 2021.
[0045] In some embodiments, as shown in Figure 1 and Figure 2As shown, the driving component 107 comprises a motor, the first moving component further comprises a gear 105 and a rack 106, the gear 105 is in transmission connection with the output shaft of the motor, and the two ends of the rack are respectively in transmission connection with the gear 105 and the first slider 108. When the dust collection operation of the base station 1 is performed, the motor rotates forward, drives the gear 105 to rotate forward, drives the rack 106 to drive the first slider 108 to move towards the second slider 1042, and then drives the second slider 1042 and the first sealing component 102 to move towards the dust outlet 2021, so as to realize the sealed communication between the dust outlet 2021 and the dust suction port 109. When the dust collection operation of the base station 1 is completed, the motor reverses, drives the gear 105 to reverse, drives the rack 106 to drive the first slider 108 to move away from the second slider 1042, and then drives the second slider 1042 and the first sealing component 102 to move away from the dust outlet 2021. The disengagement of the first sealing component 102 from the dust outlet 2021, with the disengagement of the first slider 108 from the second slider 1042, drives the second slider 1042 to reset the first sealing component 102, i.e. the first sealing component 102 is reset back to the base station 1.
[0046] In some embodiments, the first slider 108 can be directly in transmission connection with the rack 106. Alternatively, in other embodiments, the number of the first sliders 108 is two, and the first slider 108 is in transmission connection with the rack 106 through a U-shaped connecting rod 110. Figure 2 As shown, the two first sliders 108 are in transmission connection with the rack 106 through the U-shaped connecting rod 110, specifically, the opening (i.e. the top end) of the U-shaped connecting rod 110 is connected with the first slider 108, and the bottom end of the U-shaped connecting rod 110 is connected with the end of the rack 106. The number of the second sliders 1042 is also two, and they are respectively arranged on the two sides of the support framework 1041. In this way, while maintaining a set of driving component 107, gear 105 and rack 106, the two second sliders 1042 can be driven to move simultaneously, improving the stability of the movement of the support framework 1041, while reducing the investment in production cost.
[0047] Of course, the driving component 107 and the first moving component can also have other forms of structures, for example, the driving component 107 comprises a hydraulic machine, the first moving component comprises a telescopic rod, the two ends of the telescopic rod are respectively in transmission connection with the hydraulic machine and the first slider 108, and the telescopic rod is driven to extend or retract by the hydraulic machine, so as to realize the movement of the first slider 108 towards or away from the second slider 1042.
[0048] In some embodiments, the sealing device further comprises a resetting component, which is configured to drive the second slider 1042 to move towards the second sealing component 103 when the driving component 107 drives the first slider 108 to move away from the second slider 1042. Thus, it is ensured that the first sealing component 102 can be disengaged from the dust outlet 2021 when the dust collection operation of the base station 1 is completed, and can be reset back to the base station 1.
[0049] In some embodiments, referring to Figure 3 and Figure 4 As shown, the reset component includes a compression spring 1043 arranged on the side of the second sliding block 1042 close to the first sealing component 102. Specifically, the side of the second sliding block 1042 close to the first sealing component 102 is provided with a post 1044, and the compression spring 1043 is sleeved on the post 1044. When the base station 1 performs dust collection, the second sliding block 1042 moves towards the dust outlet 2021, and the end of the compression spring 1043 away from the second sliding block 1042 can abut against the base top plate 1011 of the base station base 101, so that the compression spring 1043 is compressed and stores elastic potential energy. When the dust collection is completed, the first sliding block 108 moves away from the second sliding block 1042, and the compression spring 1043 releases the elastic potential energy to drive the second sliding block 1042 to move away from the dust outlet 2021, so that the first sealing component 102 can be separated from the dust outlet 2021 and reset back to the base station 1.
[0050] Of course, the reset component is not limited to the compression spring 1043. For example, in some embodiments, the reset component includes an elastic rubber piece, an air bag, etc.
[0051] In some embodiments, the sealing device further includes a limiting structure 1012 which can abut against the second sliding block 1042, so that the limiting structure 1012 can prevent the second sliding block 1042 from moving in a non-axial direction. According to an embodiment of the sealing device of the utility model, the sealing device is arranged in the base station base 101 of the base station 1. As shown in Figure 6 , the limiting structure 1012 is formed on the base top plate 1011 of the base station base 101.
[0052] In the sealing device of the utility model, the limiting structure can have various forms. For example, an axial sliding groove is formed in the limiting structure, and the moving assembly 104 has a sliding block which is in sliding cooperation with the sliding groove to realize stable axial movement of the moving assembly. Alternatively, in some embodiments, as shown in Figure 6 , the limiting structure 1012 includes a plurality of rib strips 1013 which abut against the side of the second sliding block 1042 away from the support framework 1041. In this way, the limiting structure can be simplified, and the second sliding block 1042 can stably move in an axial direction under the limiting action of the rib strips 1013, so that the first sealing component 102 can be in sealed communication with the dust outlet 2021.
[0053] The utility model also provides a cleaning equipment, referring to Figures 1-7As shown, the cleaning device includes a base station 1, a self-moving robot 2, and the aforementioned sealing device for sealingly connecting the dust suction port 109 of the base station 1 and the dust discharge port 2021 of the self-moving robot 2. The self-moving robot 2, for example, includes but is not limited to a self-moving robot with a drum wet cleaning element, in combination with Figure 1 As shown, the dust discharge port 2021 of the self-moving robot is located at the bottom thereof, and the dust suction port 109 of the base station 1 is located in the base station base 101. The sealing device provided by the utility model can seally connect the dust discharge port 2021 and the dust suction port 109. Thus, the self-moving robot 2 collects garbage in the dust box 201 during the cleaning process. The outlet of the dust box 201 is provided with an exhaust port baffle 2011. The outlet of the dust box 201 can be connected with a dust discharge cavity 202. The dust discharge port 2021 is arranged at the outlet of the dust discharge cavity 202. The self-moving robot 2 returns to the base station base 101 of the base station 1. The base station 1 starts the dust collection operation. The motor drive gear 105 rotates in the forward direction. The first sliding block 108 is driven by the rack 106 to move towards the second sliding block 1042. The second sliding block 1042 drives the support framework 1041 and the first sealing component 102 to move towards the dust discharge port 2021, so that the sealing device seals and connects the dust suction port 109 and the dust discharge port 2021. The fan in the base station 1 starts to generate negative pressure. At this time, the exhaust port baffle 2011 of the dust box 201 is opened. The dust discharge cavity 202, the dust discharge port 2021, the sealing device, the dust suction port 109, and the base station air duct form a sealed dust collection channel. The garbage in the dust box 201 enters the dust bag for collection through the sealed channel. After the dust collection operation is completed, the motor drive gear 105 reverses. The first sliding block 108 is driven by the rack 106 to move away from the second sliding block 1042. The second sliding block 1042 is reset under the action of the compression spring 1043, and drives the first sealing component 102 to return to the base station base 101.
