[0038] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0039] With the rapid development of computer technology and artificial intelligence, intelligent devices are gradually entering every household. Robotic sweepers, for example, are a type of intelligent cleaning device. Also known as vacuum cleaners or smart vacuums, they are a type of smart home appliance. Leveraging a certain level of artificial intelligence, these devices can automatically clean the floor of a room. When operating, a robot vacuum typically uses a brush to sweep dust into a dust inlet. A fan generates negative pressure, drawing the dust into a dust collection device. The brush and fan work together to clean the floor.

[0040] In the related art, most sweeping robots use a dust box as a dust collection device. Due to the fact that the dust inlet of the dust collection device is at a short distance from the ground, the utilization rate of the dust collection space inside the dust collection device is not high, so users need to frequently dump garbage and clean the dust collection device. To this end, the garbage inside the dust collection device needs to be compressed. However, the compressed garbage is easy to block the air suction port, affecting the effect of the dust collection device in collecting garbage, and giving users a poor user experience.

[0041] In order to solve the above technical problems, the present disclosure provides a dust collecting device and a cleaning device.

[0042] According to a first aspect of the present disclosure, a dust collecting device is provided, which is applied to a cleaning device, such as Figure 1-8 As shown, the dust collecting device includes a housing 10 and a compression mechanism 20 .

[0043] The shell 10 has a first side wall 11 and a second side wall 12 that are intersecting. The first side wall 11 and the second side wall 12 enclose and define the shell 10. The first side wall 11 has an air suction port 13 and a dust collection port 14 that are oppositely arranged. The compression mechanism 20 is located in the shell 10. The compression mechanism 20 has a fixed end 21 and a free end 22 that are far away from each other. The fixed end 21 is connected to the shell 10, and the free end 22 moves in the shell 10 toward the side close to the second side wall 12 to squeeze the garbage in the shell 10.

[0044] The housing 10 serves as the outer shell of the dust collector and is primarily used to provide storage space for garbage. The housing 10 can be made of a plastic material, such as acrylonitrile butadiene styrene (ABS), polyoxymethylene (POM), polystyrene (PS), polymethyl methacrylate (PMMA), polycarbonate (PC), or polyethylene glycol terephthalate (PET), to reduce the weight of the dust collector and facilitate its removal and placement. Of course, the present disclosure is not limited thereto. In other embodiments, the housing 10 can also be made of a metal material, such as aluminum, aluminum alloy, copper, copper alloy, iron, or stainless steel, to increase the strength of the housing 10 and extend its service life.

[0045] Specifically, the shape and structure of the housing 10 can be designed according to actual needs, and the present disclosure does not make any specific limitations thereto.

[0046] The air suction port 13 can be used to connect with the dust extraction mechanism of the cleaning equipment. For example, the dust extraction mechanism can be specifically an exhaust fan. After the dust extraction mechanism is started, the exhaust fan is used to exhaust air from the shell 10, which can form a negative pressure in the shell 10 and generate suction, thereby sucking dust and other garbage into the shell 10 for collection and temporary storage.

[0047] The compression mechanism 20 is used to squeeze the garbage in the shell 10. The compression mechanism 20 has a fixed end 21 and a free end 22 that are far away from each other. The fixed end 21 is connected to the shell 10, and the free end 22 moves in the shell 10 toward the side close to the second side wall 12 to squeeze the garbage in the shell 10. The compression mechanism 20 squeezes the garbage in the shell 10 in a direction avoiding the air suction port 13 and / or the dust collection port 14.

[0048] In the present disclosure, a compression mechanism 20 is provided in the shell 10, so that the limited space in the dust collecting device is efficiently utilized, which effectively reduces the frequency of users dumping garbage. The free end 22 of the compression mechanism 20 moves in the shell 10 toward the side close to the second side wall 12 to squeeze the garbage in the shell 10, thereby avoiding the compressed garbage blocking the air intake 13 and affecting the effect of the dust collecting device in collecting garbage, thereby greatly improving the user experience.

[0049] In some possible implementations, such as Figure 1 and Figure 5-6 As shown, the first side wall 11 includes a first sub-side wall 111 and a second sub-side wall 112 that are oppositely arranged. The air suction port 13 is located on the first sub-side wall 111 , and the dust collection port 14 is located on the second sub-side wall 112 .

[0050] The first sub-side wall 111 may be a rectangular parallelepiped or a square to make its shape more regular and easier to form and manufacture. Of course, in other embodiments, the first sub-side wall 111 may also be of other shapes and structures. The embodiment of the present disclosure does not limit the specific shape of the first sub-side wall 111.

[0051] The second sub-sidewall 112 may be a rectangular parallelepiped or a square to make its shape more regular and easier to form and manufacture. Of course, in other embodiments, the second sub-sidewall 112 may also be of other shapes and structures. The embodiment of the present disclosure does not limit the specific shape of the second sub-sidewall 112.

[0052] In the embodiment of the present disclosure, the air suction port 13 and the dust collection port 14 are respectively arranged on the opposite first sub-side wall 111 and second sub-side wall 112 of the shell 10, so that the dust collection device can easily collect garbage in the shell 10 through the dust collection port 14.

[0053] In some possible implementations, such as Figure 2-8As shown, the second sidewall 12 includes a third sub-sidewall 121 and a fourth sub-sidewall 122 oppositely disposed along a first direction, and the first sub-sidewall 111 and the second sub-sidewall 112 oppositely disposed along a second direction, the first direction being different from the second direction.

[0054] Among them, such as Figure 5 and Figure 8 As shown, the first direction may be the up-down direction of the dust collecting device, the second direction may be the left-right direction of the dust collecting device, and the first direction and the second direction are perpendicular to each other.

[0055] The third sub-sidewall 121 may be a rectangular parallelepiped or a square to make its shape more regular and easier to form and manufacture. Of course, in other embodiments, the third sub-sidewall 121 may also be of other shapes and structures. The embodiment of the present disclosure does not limit the specific shape of the third sub-sidewall 121.

[0056] The fourth sub-side wall 122 may be a rectangular parallelepiped or a square to make its shape more regular and easier to form and manufacture. Of course, in other embodiments, the fourth sub-side wall 122 may also be of other shapes and structures. The embodiment of the present disclosure does not limit the specific shape of the fourth sub-side wall 122.

[0057] In the embodiment of the present disclosure, the third sub-side wall 121 can be the upper side wall of the shell 10, and the fourth sub-side wall 122 can be the bottom side wall of the shell 10. The free end 22 of the compression mechanism 20 moves in the shell 10 toward the side close to the third sub-side wall 121 and / or the fourth sub-side wall 122 to squeeze the garbage in the shell 10, thereby avoiding the compressed garbage blocking the air suction port 13 and affecting the effect of the dust collection device in collecting garbage, thereby greatly improving the user experience.

[0058] In some possible embodiments, the fixed end 21 is connected to the fourth sub-side wall 122, and the free end 22 rotates within the shell 10 toward the side close to the fourth sub-side wall 122, and / or the fixed end 21 is connected to the third sub-side wall 121, and the free end 22 moves within the shell 10 toward the side close to the fourth sub-side wall 122.

[0059] For example, Figure 4-6 As shown, the fixed end 21 is connected to the fourth sub-side wall 122, and the free end 22 rotates in the shell 10 toward the side close to the fourth sub-side wall 122, so that the limited space in the dust collecting device is efficiently utilized, effectively reducing the frequency of users dumping garbage, and at the same time avoiding the compressed garbage blocking the air suction port 13, affecting the effect of the dust collecting device in collecting garbage, thereby greatly improving the user experience.

[0060] For example, Figure 1-3 and Figure 7-8As shown, the fixed end 21 is connected to the third sub-side wall 121, and the free end 22 moves in the shell 10 toward the side close to the fourth sub-side wall 122, so that the limited space in the dust collecting device is efficiently utilized, effectively reducing the frequency of users dumping garbage, and at the same time avoiding the compressed garbage blocking the air suction port 13, affecting the effect of the dust collecting device in collecting garbage, thereby greatly improving the user experience.

[0061] In some possible implementations, such as Figure 2-3 、 Figure 5-6 、 Figure 7-8 As shown, the compression mechanism 20 includes a pressure piece 201, one end of the pressure piece 201 is a fixed end 21, and the other end of the pressure piece 201 is a free end 22. The pressure piece 201 is in a first state in the shell 10, and the free end 22 moves in the shell 10 toward the side close to the fourth sub-side wall 122 to squeeze the garbage in the shell 10; the pressure piece 201 is in a second state in the shell 10, and the free end 22 moves in the shell 10 toward the side close to the third sub-side wall 121, and negative pressure is formed in the shell 10 to collect garbage at the dust collecting port 14.

[0062] Among them, the first state can be understood as the state of the pressure member 201 when compressing the garbage in the shell 10, and the second state can be understood as the state of the pressure member 201 when collecting the garbage at the dust collecting port 14 into the shell 10.

[0063] In the embodiment of the present disclosure, the free end 22 of the pressure member 201 moves in the shell 10 toward the side close to the fourth sub-side wall 122 to squeeze the garbage in the shell 10, so that the limited space in the dust collecting device is efficiently utilized, effectively reducing the frequency of users dumping garbage, and at the same time avoiding the compressed garbage blocking the air suction port 13, affecting the effect of the dust collecting device in collecting garbage, thereby greatly improving the user experience.

[0064] In some possible implementations, such as Figure 1-9 As shown, the dust collecting device includes: a driving mechanism 30.

[0065] The driving mechanism 30 is mounted on the housing 10 , and is used to drive the free end 22 of the pressure member 201 to move.

[0066] In the embodiment of the present disclosure, the driving mechanism 30 drives the free end 22 of the pressure member 201 to move in the shell 10 toward the side close to the fourth sub-side wall 122 to squeeze the garbage in the shell 10, so that the limited space in the dust collecting device is efficiently utilized, effectively reducing the frequency of users dumping garbage, and at the same time avoiding the compressed garbage blocking the air suction port 13, affecting the effect of the dust collecting device in collecting garbage, thereby greatly improving the user experience.

[0067] In some possible implementations, such as Figure 1-8As shown, the driving mechanism 30 drives the free end 22 of the pressure member 201 to perform a lifting motion in the housing 10; and / or, the driving mechanism 30 drives the free end 22 of the pressure member 201 to perform a rotational motion in the housing.

[0068] For example, Figure 4-6 As shown, the driving mechanism 30 is connected to the fourth sub-side wall 122. The driving mechanism 30 drives the free end 22 of the pressure member 201 to rotate in the shell 10 toward the side close to the fourth sub-side wall 122, so that the limited space in the dust collecting device is efficiently utilized, effectively reducing the frequency of users dumping garbage, and at the same time avoiding the compressed garbage blocking the air suction port 13, affecting the effect of the dust collecting device in collecting garbage, thereby greatly improving the user experience.

[0069] For example, Figure 1-3 and Figure 7-8 As shown, the driving mechanism 30 is connected to the third sub-side wall 121. The driving mechanism 30 drives the free end 22 of the pressure member 201 to move up and down in the shell 10 toward the side close to the fourth sub-side wall 122, so that the limited space in the dust collecting device is efficiently utilized, effectively reducing the frequency of users dumping garbage, and at the same time avoiding the compressed garbage blocking the air suction port 13, affecting the effect of the dust collecting device in collecting garbage, thereby greatly improving the user experience.

The peristaltic pump is connected to the air inlet / outlet through the second pipe opening 301, so that the peristaltic pump is connected to the outside world, and the flexible airbag is inflated and deflated by the peristaltic pump to realize the expansion and retraction of the flexible airbag. Specifically, when the dust collection device finishes collecting dust, the peristaltic pump works in the forward direction to inflate the flexible airbag. The flexible airbag is expanded to press the garbage in the shell 10, realize the function of compressing the garbage, improve the utilization rate of the space in the shell 10, and avoid users from frequently dumping garbage; when the dust collection is started again, the peristaltic pump works in the reverse direction to deflate the flexible airbag, and the flexible airbag retracts to avoid obstructing the garbage from entering the shell 10 through the dust collection port 14.

One end of the connecting member 20-3 is fixed to the rotating shaft positioning block and can only rotate, while the other end of the connecting member 20-3 is fixed to the slider 20-4 and can make both rotational and linear motions. The slider 20-4 makes a reciprocating motion in the slide rail 304, while the connecting member 20-3 can shrink and stretch, driving the moving member 20-2 to press down on the garbage and retract it. The function of compressing garbage is realized, the utilization rate of the space in the shell 10 is improved, and users are prevented from frequently dumping garbage. At the same time, it does not affect the normal dust collection of the dust collection device.

[0080] In some possible implementations, such as Figure 4-6 As shown, the pressure member 201 is the third pressure member, the driving mechanism is the third driving member, the third driving member drives the third pressure member, and the third pressure member rotates in the shell 10 with the fixed end 21 of the third pressure member as the rotation axis. The third pressure member is in a first state in the shell 10, and the free end 22 of the third pressure member rotates in the shell 10 toward the side close to the fourth sub-side wall 122; the third pressure member is in a second state in the shell 10, and the free end 22 moves in the shell 10 toward the side close to the first sub-side wall 111, and negative pressure is formed in the shell 10 to collect garbage at the dust collecting port 14.

[0081] In the embodiment of the present disclosure, after the dust collecting device sucks the garbage into the housing 10, as shown in FIG. Figure 6 As shown, the third driving member drives the third pressure member, and the third pressure member rotates in the housing 10 with the fixed end 21 of the third pressure member as the rotation axis. The third pressure member rotates to compress the garbage, thereby realizing the garbage compression function, improving the utilization rate of the space in the housing 10, and avoiding users from frequently dumping garbage. After the garbage is compressed, as shown in FIG. Figure 4-5 As shown, the third pressure member rotates in the shell 10 with the fixed end 21 of the third pressure member as the rotation axis, and the free end 22 moves in the shell 10 toward the side close to the first sub-side wall 111, and the third pressure member rotates back to a position parallel to the air suction port 13, which does not affect the normal dust collection of the shell 10. After collecting dust for a certain period of time, the next rotation and garbage pressing action will be performed.

[0082] In some possible implementations, such as Figure 4 As shown, the third pressure member is a frame member 23 , and ventilation holes are evenly distributed on the frame member 23 .

[0083] The frame member may be rectangular or in other shapes, and the ventilation holes may be circular or square, which is not specifically limited in the embodiment of the present disclosure. For example, the third pressure member may be a metal mesh.

[0084] In the embodiment of the present disclosure, after the garbage is compressed, the third pressure member rotates in the shell 10 with the fixed end 21 of the third pressure member as the rotation axis, and the free end 22 moves in the shell 10 toward the side close to the first sub-side wall 111, and the third pressure member rotates back to a position parallel to the air suction port 13. The frame member 23 evenly distributed with ventilation holes serves as the third pressure member, so it will not affect the airflow between the dust collecting port 14 and the air suction port 13, and thus will not affect the normal dust collection of the shell 10.

[0085] In some possible implementations, such as Figure 4-5 As shown, the third driving member includes: a second motor 306 .

[0086] The output end of the second motor 306 is coaxially connected to a rotating shaft (not shown in the figure), which is connected to the housing 10 through a support base 307 and is connected to one end of the rotating shaft of the third driving member.

[0087] In the disclosed embodiment, a stopper 308 is provided on the side wall where the air inlet 13 is located. The rotating shaft is connected to the housing 10 via a support base 307. The second motor 306 is driven by a gear transmission to drive the frame member 23 to rotate. The second motor 306 is stopped by the current level. When the frame member 23 compresses the garbage to a certain extent, the current increases to a certain value, the second motor 306 reverses, rotates to the position of the stopper 308, the current increases, and the second motor 306 stops. When the dust collection device sucks the garbage into the housing 10, the frame member 23 rotates, compressing the garbage, realizing the garbage compression function, which can improve the utilization rate of the internal space of the housing 10, avoid users from frequently dumping garbage, and enhance the user experience.

[0088] In some possible implementations, such as Figure 1 As shown, the shell 10 is provided with a cleaning port 15 , which is located on the first side wall 11 . The dust collecting device further includes: a baffle 40 and a cleaning door 50 .

[0089] The baffle 40 is disposed at the dust collecting port 14 ; the cleaning door 50 is disposed at the cleaning port 15 .

[0090] In the embodiment of the present disclosure, the baffle 40 is hingedly arranged at the dust collecting port 14. When the dust collecting device needs to collect garbage, negative pressure is formed in the shell 10. At this time, the baffle 40 will rotate relative to the second sub-side wall 112, and will not hinder the garbage from entering the shell 10 from the dust collecting port 14; when it is necessary to clean the compressed garbage in the shell 10, the compressed garbage is cleaned by opening the cleaning door 50.

[0091] In some possible implementations, such as Figure 1-4 、 Figure 7-8 As shown, the dust collecting device further includes: a socket 60.

[0092] The socket 60 is disposed on the first side wall 11 , and the driving mechanism 30 is powered through the socket 60 .

[0093] In the embodiment of the present disclosure, the socket 60 can be a charging spring, which enables the controller of the cleaning device to power the driving mechanism 30 inside the dust collection device.

[0094] Based on the same inventive concept, according to a second aspect of the present disclosure, a cleaning device is provided, comprising: a dust collecting device as in any embodiment of the first aspect described above.

[0095] Among them, the cleaning equipment can be a cleaning equipment such as a sweeper, a scrubber, a mop, etc. that has a dust collection device that can compress garbage.

[0096] In the present disclosure, a compression mechanism 20 is provided in the shell 10, so that the limited space in the dust collecting device is efficiently utilized, which effectively reduces the frequency of users dumping garbage. The free end 22 of the compression mechanism 20 moves in the shell 10 toward the side close to the second side wall 12 to squeeze the garbage in the shell 10, thereby avoiding the compressed garbage blocking the air intake 13 and affecting the effect of the dust collecting device in collecting garbage, thereby greatly improving the user experience.
