The specific meaning of these terms in this application will be understood by those of ordinary skill in the art as appropriate.

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

Along with the development of technology, various cleaning devices, such as cleaning robots, cleaning base stations or handheld cleaning devices, have been widely used in various industries, and have also been used in the work and life of people, thereby bringing great convenience to the life of people. For cleaning devices with dry garbage collection, it is generally desirable that the garbage collection container is large, so that the maintenance frequency of users is low, and the user experience is improved.

The garbage collection module of the cleaning equipment is mainly improved, so that the maintenance frequency of users is reduced, and the user experience is improved.

The cleaning robot according to the embodiment of the application is a self-moving robot, and includes, but is not limited to, a sweeping robot only used for sweeping, and may further include a sweeping and mopping robot capable of sweeping and mopping, in which a dust collecting container is required to be set, so as to collect dust particles and garbage on a surface to be cleaned in the process that the cleaning robot performs sweeping and dust collection tasks on the surface to be cleaned.

The hand-held cleaning device is used for cleaning dust particles on a surface to be cleaned by holding the hand of a user, and the hand-held cleaning device (such as a hand-held dust collector) is also provided with a dust collecting container for collecting dust particles and garbage on the surface to be cleaned during the process of sweeping, sucking dust and the like on the surface to be cleaned.

The base station refers to a cleaning device used in cooperation with a cleaning robot or a handheld cleaning device. In order to facilitate the use of users, the base station is often matched with the cleaning robot or the handheld cleaning equipment to provide nursing for the cleaning robot or the handheld cleaning equipment, so that the maintenance frequency of the users to the cleaning robot or the handheld cleaning equipment is reduced. For example, the base station may be used to charge, collect dust, clean, and wipe a cleaning robot or a handheld cleaning device, and in particular, the base station may have a dust bag, and the base station may suck dust particles collected by the cleaning robot or the handheld cleaning device into the dust bag of the base station after each sweeping or sucking task performed by the cleaning robot or the handheld cleaning device, so as to collect dust, and after multiple dust collection (e.g., 2 to 3 months), the user may discard the dust bag of the base station, so as to reduce the frequency of maintenance of the dust collection container by the user.

It is noted that, for a cleaning robot with sweeping and mopping functions, the base station can also clean the mopping member (such as mop) of the cleaning robot, and after the mopping member of the cleaning robot mops the floor, the mopping member tends to become dirty and needs to be cleaned. For this purpose, the base station can be used for cleaning the mop of the cleaning robot. Specifically, the cleaning robot may be moved to the base station so that the cleaning mechanism on the base station automatically cleans the cleaning robot's mop. Besides the functions, the base station can also be used for maintaining and managing the cleaning robot, so that the cleaning robot can be controlled more intelligently in the process of executing the cleaning task, and the working intelligence of the robot is improved.

It should be noted that, the "surface to be cleaned" in the embodiments of the present application may be a floor, a wall, a bed surface, a sofa surface, a table top, or the like. The present application is not particularly limited. "dust particles" as described in embodiments of the present application include, but are not limited to: dirt, cobble, hair, paper, etc.

As described above, in order to reduce the frequency of maintenance of the dust container by a user, whether it is a cleaning robot, a hand-held cleaning device, or a base station, it is generally desirable that the effective dust collecting space of the dust container is relatively large so as to ensure that the dust container is discarded or maintained for a longer period of time. However, since the cleaning apparatus has a limited volume, the inner space is also limited, which in turn results in a limited accommodating space for the dust collection container. Therefore, how to increase the effective volume of the dust collecting container as much as possible in a limited space is a technical problem to be solved by the present application.

To solve the above-mentioned technical problems, the cleaning device provided in the embodiments of the present application is configured to remove and collect dust particles and garbage by generating an air flow. In the following, the cleaning device will be described as an example of a cleaning robot having a dust container configured to collect dust particles and debris cleaned by the cleaning robot during a sweeping and sucking operation, the dust container may be made of one or more flexible materials. By way of example, the dust collection container may comprise a bag of organic or non-organic flexible material, such as plastic, wool, cotton wool, nonwoven or any other fabric known in the art. The flexible material may be breathable or impermeable to air. The dust container may have an air inlet receiving an air flow carrying dust particles during a cleaning operation of the cleaning robot on the surface to be cleaned, the dust particles being collected in the dust container, and the air flow being discharged through the air outlet of the dust container.

In order that dust particles of a surface to be cleaned may enter the dust collection container, in an embodiment of the application, the cleaning robot may further comprise a sweeping module. The floor module may include a roller brush assembly and/or an edge brush assembly. The rolling brush assembly can comprise a rolling brush installation shell and a rolling brush installed in the rolling brush installation shell, and the rolling brush can be cylindrical and is rotatably arranged in the rolling brush installation shell. In a mounted state in which the rolling brush assembly is mounted to the cleaning robot, the rotation axis of the rolling brush may be parallel to the surface to be cleaned. The rotation axis of the side brush assembly may be disposed perpendicular to or at an acute angle to the surface to be cleaned to gather the dust from outside to inside the cleaning robot, the cleaning robot having an air inlet communicating with the dust collection container, the roller brush and/or the side brush being configured to guide dust particle dust of the surface to be cleaned to the air inlet.

The cleaning device provided in the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1D, a cleaning apparatus (illustrated as a cleaning robot) provided in an embodiment of the present application includes a mounting chamber 11 and a dust collection container 12 provided in the mounting chamber 11. Specifically, the cleaning apparatus may include an apparatus main body 10, and a cover 13 openable and removable from the apparatus main body 10, the installation chamber 11 is provided to the apparatus main body 10, and the installation chamber 11 has an opening for the cover 13 to be covered at least at an opening side of the installation chamber 11. The cover 13 can cover the dust collecting container 12 in the installation cavity 11, at least can limit the escape and beautiful effect of the dust collecting container 12. The cover 13 and/or the apparatus body 10 may be provided with a seal disposed around the opening, the seal being for enabling the installation chamber 11 to form a sealed space.

As shown in fig. 1A and 1B, a first cavity 11C is formed inside the installation cavity 11, the first cavity 11C is defined by a cavity wall of the installation cavity 11, and a first air inlet 111 communicating with the first cavity 11C is provided in the installation cavity 11. Dust particles and other garbage collected from the outside enter the installation chamber 11 through the first air inlet 111 and are stored in the dust collection container 12. The installation chamber 11 may be formed directly from the apparatus body 10, and the installation chamber 11 may be a separate bin body, which is separately manufactured from the apparatus body 10 and assembled in the apparatus body 10.

Referring to fig. 4A to 4C, a second chamber 12C for collecting garbage is formed inside the dust collection container 12, and the dust collection container 12 further has a second air inlet 121 communicating with the second chamber 12C. Correspondingly, a first cavity 11C is formed inside the installation cavity 11, the installation cavity 11 is provided with a first air inlet 111 respectively communicated with the first cavity 11C, and the second air inlet 121 is used for being in butt joint communication with the first air inlet 111. When the dust collection container 12 is installed in the first cavity 11C of the installation cavity 11, the first air inlet 111 is in butt joint communication with the second air inlet 121.

Referring to fig. 2A, in some embodiments, when the installation chamber 11 is a separate bin, the embodiments also provide a dust collecting device, which may include a housing and a dust collecting container 12, the dust collecting device being detachably installed in the cleaning apparatus, the housing being the installation chamber 11, the interior of which forms a first cavity 11C, the housing having a first air inlet 111 and a first air outlet 112 communicating with the first cavity 11C; the dust collection container 12 is disposed in the first chamber 11C and includes a dust bag 124, a second chamber 12C for collecting garbage is formed inside the dust bag 124, and the dust collection container 12 has a second air inlet 121 communicating with the second chamber 12C. The cleaning apparatus is provided with a negative pressure device, and when the dust collecting container 12 is mounted in the housing, the first air inlet 111 can be in butt-joint communication with the second air inlet 121, and the first air outlet 112 is used for being in fluid communication with the negative pressure device, so that the negative pressure device can exhaust air from the first cavity 11C.

In some embodiments, as shown in connection with fig. 5A, the cleaning apparatus comprises a mounting chamber 11, a dust collection container 12 and a negative pressure device 131, the dust collection container 12 may in particular comprise a dust bag 124, for example, the dust bag 124 may be a disposable dust bag, which may be discarded directly after a period of use. The dust bag 124 defines a second chamber 12C therein for collecting waste, and a negative pressure device is in fluid communication with the first air outlet 112 for at least evacuating the first chamber 11C such that the air pressure within the first chamber 11C is lower than the air pressure within the second chamber 12C.

As shown in fig. 5A to 5C, in some embodiments, the dust collecting container 12 may have a second air outlet 120, the second air outlet 120 may be in communication with a negative pressure device, when the negative pressure device works, a suction airflow may be generated, so that the airflow carrying dust particles and garbage enters the second cavity 12C of the dust bag 124 through the first air inlet 111 and the second air inlet 121, the dust particles and garbage are collected in the second cavity 12C, and air flows out through the second air outlet 120 and the negative pressure device, so that external garbage is sucked into the dust collecting container 12 by using the negative pressure for garbage collection.

In other embodiments, the dust bag 124 may collect dust without the need for a negative pressure device to pump the second chamber 12C, for example, dust particles (particularly larger particles) may be picked up from the surface to be cleaned by a cleaning apparatus sweeping module (e.g., a roller brush assembly and/or an edge brush assembly) and thrown directly towards the first and second air inlets 111, 121, for which case no suction airflow is required to be generated in the second chamber 12C, i.e., no negative pressure device is required to pump the dust bag 124.

Of course, the negative pressure device can be used to pump negative pressure into the dust bag 124, and the sweeping module can be used to sweep dust particles and debris directly into the second cavity 12C of the dust bag 124.

In the case where there is a negative pressure device that draws a negative pressure to the second chamber 12C, in order to enable the negative pressure device to communicate with the first chamber 11C through the first air outlet 112, there may be the following three embodiments:

as shown in fig. 5A, the dust collecting container 12 has a second air outlet 120, the first air outlet 112 is in fluid communication with the second air outlet 120, and the negative pressure device 131 is connected to the first air outlet 112, and a gap is provided between the first air outlet 112 and the second air outlet 120, so that the negative pressure device 131 can be in fluid communication with the first chamber 11C and the second chamber 12C at the same time, so that the negative pressure can be simultaneously pumped to the first chamber 11C and the second chamber C by one negative pressure device 131.

As shown in fig. 5B, there are two negative pressure devices, one 131 and the other 132, which are communicated with the second air outlet 120 of the dust collecting container 12 through the negative pressure device 132, so that the negative pressure device 132 can pump negative pressure to the second chamber 12C, the negative pressure device 131 is directly communicated with the first chamber 11C, and the negative pressure device 131 is indirectly communicated with the second chamber 12C, so that the negative pressure device 131 pumps negative pressure to the first chamber 11C and the second chamber 12C.

As shown in fig. 5C, there are two negative pressure devices, one 131 communicating with the first chamber 11C and the other 132 communicating with only the second air outlet 120 of the dust collection container 12, so that the negative pressure device 132 can pump negative pressure to the second chamber 12C. At this time, the first air outlet 112 and the second air outlet 120 do not need to communicate.

That is, the cleaning apparatus may simultaneously vacuumize the first chamber 11C and the second chamber 12C of the dust collection container 12 by using one negative pressure device 131, or may vacuumize the first chamber 11C and the second chamber 12C by using two negative pressure devices 131, 132, respectively. In some embodiments, the cleaning apparatus may be provided with a filter structure 122, see fig. 4A-5C, and the cleaning apparatus further comprises a filter structure 122 for filtering the gas flowing from the second chamber 12C. The air resistance of the dust bag 124 during air outlet can be increased through the filtering structure 122, when the negative pressure device is utilized to pump air from the installation cavity 11, the flow rate of air in the dust bag 124 can be obviously smaller than the flow rate of air in the installation cavity 11, the flow rate pumped from the second cavity 12C is smaller than the flow rate pumped from the first cavity 11C, the air pressure in the dust bag 124 is larger than the air pressure in the installation cavity 11, and the pressure difference between the inside of the dust bag 124 and the inside of the installation cavity 11 is gradually increased along with the continuous pumping of the negative pressure device, so that the dust bag bulges. And dust, hair and other garbage in the air enter the dust bag 124 and are blocked by the filtering structure 122 to be collected in the second cavity 12C of the dust bag 124, the swelled dust bag 124 is more convenient for filling the dust, particles, hair and other garbage, and the effective use volume of the dust bag 124 is increased, so that the space in the dust bag 124 is fully utilized.

As shown in fig. 2A to 4A and fig. 5A to 5C, in some embodiments, the dust bag 124 may be made of airtight material, the filtering structure 122 may be disposed on the dust collecting container 12 and located at the second air outlet 120, when the dust collecting container 12 is installed in the installation cavity 11, the negative pressure device pumps the first air outlet 112 and simultaneously pumps the space between the dust collecting container 12 and the installation cavity 11, and due to the wind resistance of the filtering structure 122, the air pressure in the first cavity 11C is lower than the air pressure in the second cavity 12C, and the dust bag 124 may bulge; meanwhile, in the air exhausting process of the negative pressure device, air mixed with garbage sequentially passes through the first air inlet 111 and the second air inlet 121 and then enters the second cavity 12C, the air is filtered by the filtering structure 122 and then is discharged from the first air outlet 112, dust, particles, hair and other garbage in the air are blocked by the filtering structure 122 and are collected in the second cavity 12C, so that garbage collection is realized, when the negative pressure device continuously exhausts, the dust bag 124 continuously bulges, and more garbage can be filled in the dust bag 124.

It will be appreciated that in other embodiments, the filter structure 122 may also be provided on the mounting chamber 11. For example, as shown in fig. 6, the installation chamber 11 further has a third air outlet 113, and a filtering structure 122 is disposed at the third air outlet 113. And the filter structure 122 is in sealing butt joint with the second air outlet 120 (the sealing butt joint can be realized through the first sealing element O), so that the filter structure 122 is communicated with the first cavity 11C of the dust bag 124, and the sealing butt joint of the filter structure 122 and the second air outlet 120 can prevent dust particles and garbage in the dust bag 124 from leaking from the second air outlet 120 in the dust collection process.

In order to form a pressure difference between the first chamber 11C and the second chamber 12C such that the pressure of the first chamber 11C is lower than the pressure of the second chamber 12C, at least the following embodiments are possible:

first, the second air outlet 120 and/or the third air outlet 113 may have a filtering structure 122, and the filtering structure 122 may increase the wind resistance when the dust bag 124 is exhausted, such that when the first chamber 11C and the second chamber 12C are exhausted by the negative pressure device 131, the flow rate of the air extracted from the dust bag 124 is smaller than the flow rate extracted from the installation chamber 11 (i.e., the first chamber 11C), so that the air pressure of the second chamber 12C is greater than the air pressure in the first chamber 11C, so that the dust bag 124 is "swelled".

Second, the dust collecting container 12 is not provided with an air outlet, dust particles and garbage are directly swept into the dust collecting container 12 through the sweeping module, when negative pressure is pumped to the first cavity 11C through the first air outlet 112 by the negative pressure device 131, the second cavity 12C of the dust collecting container 12 is communicated with the atmosphere, and the first cavity 11C outside the dust collecting container 12 is pumped with negative pressure, so that air pressure in the dust collecting container 12 is greater than air pressure in the first cavity 11C, and the dust bag 124 is "bulged".

Third, the dust container 12 has the second air outlet 120, but neither the dust container 12 nor the installation chamber 11 is provided with the filter structure 122, but is communicated with the first chamber 11C and the second chamber 12C by two negative pressure devices, respectively, and the flow rates of the two negative pressure devices are controlled to be different. Specifically, the flow rate of the negative pressure device in communication with the first chamber 11C may be controlled to be greater than the flow rate of the negative pressure device in communication with the second chamber 12C, and the air pressure in the dust collecting container 12 may be made to be greater than the air pressure in the first chamber 11C, so that the dust bag 124 "bulges".

Any of the above implementations may be selected by those skilled in the art according to specific needs, and the embodiments of the present application are not particularly limited, as long as the dust bag 124 can be "inflated" by controlling the air pressure of the first chamber 11C to be smaller than the air pressure of the second chamber 12C.

According to the cleaning device provided by the embodiment of the application, the dust collecting container 12 is placed in the installation cavity 11, and the installation cavity 11 and the air inlet (the second air inlet 121) of the dust collecting container 12 are in butt joint communication, so that the first air outlet 112 of the installation cavity 11 is communicated with a space formed between the installation cavity 11 and the dust bag 124; through negative pressure device and first air outlet 112 fluid communication, can be to the installation cavity 11 in the gas extraction for the gas between installation cavity and the dirt bag is taken out, and the atmospheric pressure in the first intracavity of installation cavity is lower than the atmospheric pressure in the second intracavity of dirt bag, thereby, dirt bag 124 can bulge under the negative pressure effect, has increased the effective use volume of dirt bag 124, and more rubbish can be packed to the dirt bag of same volume.

Particularly, when the cleaning device is a cleaning robot or a handheld cleaning device, the cleaning robot or the handheld cleaning device is provided with the disposable dust bag, and the dust bag can be fully bulged by pumping negative pressure into the dust bag installation cavity, so that the effective volume of the dust bag can be increased, dust particles and garbage can be collected into the dust bag by the cleaning robot or the handheld cleaning device in the cleaning process of the surface to be cleaned, and the dust bag can be discarded after being used for multiple times due to the large effective volume of the dust bag.

As is well known, in the related art, dust collection is performed on a cleaning robot or a handheld cleaning device by using a dust collection base station, the cleaning robot or the handheld cleaning device needs to be in butt joint with the dust collection base station, garbage in a dust collection container of the cleaning robot or the handheld cleaning device is collected into a recovery device of the dust collection base station, as a dust collection channel of the dust collection base station is longer and a dust collection path is farther, the garbage in the dust collection container of the cleaning robot or the handheld cleaning device can be fully sucked and cleaned by using a dust collection fan with higher power, and therefore, the dust collection process of the base station is usually quite noisy. And the dust bag of this application is owing to can bulge, and its effective volume is also great, can guarantee that the dust bag need not to be thrown away for a long time for the frequency that the user thrown away the dust bag is also less, and the cost is also lower.

In addition, since the dust box may have sharp corners, as compared to a conventional dust box made of a rigid material such as hard plastic or metal, debris (e.g., dust particles, dirt, and hair) may become caught in these sharp corners and accumulate after the cleaning apparatus is operated for a long period of time. Excessive accumulation of debris can reduce the efficiency and effectiveness of the dust box. Conversely, the dust collection container 12 disclosed herein may include a flexible dust bag without sharp corners. There are few sharp corners after the dust bag 124 bulges, and therefore, the cleaning efficiency and cleaning effect of the cleaning apparatus can be maintained even after the cleaning apparatus is used for a long period of time.

Illustratively, the negative pressure device 131 may pump the first chamber 11C and the second chamber 12C simultaneously (fig. 5A, 6), or both negative pressure devices 131, 132 pump the first chamber 11C and the second chamber 12C respectively (fig. 5B, 5C). In the process of exhausting the first cavity 11C through the first air outlet 112 by the negative pressure device, air entering the dust bag 124 is also pumped out of the filtering structure 122, so that the filtering and collecting of the garbage are realized.

In other embodiments, the cleaning apparatus may further include a dust collecting cover plate detachably fixed at the first air outlet 112 of the installation chamber 11, and when the dust bag 124 needs to be installed in the installation chamber 11, the dust collecting cover plate may be opened or removed, so that the second air outlet 120 of the dust bag 124 is in butt-joint communication with the first air outlet 112; when the dust bag 124 is taken out, the dust collecting cover plate can be shielded at the first air outlet 112, so that ash leakage at the dust collecting cover plate can be avoided. For example, the dust collecting cover plate can be detachably fixed to the installation chamber 11 through a buckle, or can be rotatably arranged in the installation chamber 11 through a hinge structure.

By providing the filter structure 122 on the mounting chamber 11, the filter structure 122 does not need to be integrated with the dust collection container 12, the use cost of the dust collection container 12 is reduced, and the dust collection bag 124 can be directly discarded after being filled, so that the dust collection container is more economical and practical. The filter structure 122 is disposed in the dust collecting container 12, since the filter structure 122 is directly disposed in the dust collecting container 12, the garbage in the dust collecting container 12 will not leak from the second air outlet 120, so that the seal between the filter structure 122 and the first air outlet 112 is not needed, on the one hand, the difficulty of structural design can be reduced, and on the other hand, since there is no seal between the filter structure 122 and the first air outlet 112, there is no frictional interference between the first air outlet 112 and the filter structure 122 during the process of taking and placing the dust collecting container 12, so that the taking and placing experience is better.

In other embodiments, as shown in fig. 4B and 4C, the dust bag 124 may be made of a breathable material, and the dust bag 124 may have a plurality of breathable mesh openings. For example, in the embodiment shown in FIG. 4B, at least a portion of the air permeable mesh of the dust bag 124 forms the second air outlet 120, and the dust bag 124 itself forms the filter structure 122; alternatively, in the embodiment shown in fig. 4C, for example, the second air outlet 120 of the air-permeable dust bag 124 is further provided with a filtering structure 122, and the dust bag 124 itself and the filtering structure 122 can pass through air.

Illustratively, the filter structure 122 includes at least one of a tissue paper, a nonwoven fabric, and both dust and trash filtration may be achieved. Meanwhile, when the filter structure 122 adopts the HEPA paper, the water in the air can be filtered, so that the water content in the extracted air is prevented from being larger, and a certain protection effect is achieved on the negative pressure device.

As shown in fig. 5A to 6, in some embodiments, the first chamber 11C may be a closed chamber, so as to enhance the air pumping effect of the negative pressure device. The first air inlet 111 and the second air inlet 121 are in sealing butt joint, so that a closed space can be formed between the dust bag 124 and the installation cavity 11. In order to realize the sealing and butt joint of the first air inlet 111 and the second air inlet 121, a second sealing member P may be disposed between the first air inlet 111 and the second air inlet 121 (the second sealing member P may be disposed on the installation chamber 11 or the dust collecting container 12), and after the dust bag 124 is installed in the installation chamber 11, the second sealing member P is elastically compressed between the first air inlet 111 and the second air inlet 121. The first air outlet 112 is configured to receive air in the enclosed space such that the air pressure in the enclosed space is lower than the air pressure in the second chamber 12C. In the air extraction process of the negative pressure device, the air mixed with the garbage sequentially passes through the first air inlet 111 and the second air inlet 121 and then enters the second cavity 12C, and cannot leak out from the butt joint part between the first air inlet 111 and the second air inlet 121, so that the air pressure of the airtight space between the dust bag 124 and the installation cavity 11 is reduced more conveniently, and the dust bag 124 is swelled rapidly. In some embodiments, as shown in fig. 2B, the dust collection container 12 includes a mounting member 123 for mounting to the cleaning apparatus and a flexible dust bag 124, the mounting member 123 and the dust bag 124 enclosing a second chamber 12C for receiving the dust, the dust collection container 12 being removably connected to the mounting chamber 11 by the mounting member 123. At least one of the second air inlet 121 and the second air outlet 120 is disposed on the mounting member 123, for example, the second air inlet 121 and the second air outlet 120 are both disposed on the mounting member 123. Illustratively, the dust bag 124 may be secured to the mounting member 123 by means of adhesive, clamping, or the like, the mounting member 123 may be a hard material, may be configured as a mounting plate, for example, a plastic plate, a cardboard, or even a metal plate, may be removably mounted within the mounting chamber 11 by means of clamping, interference fit, or the like, and thus mounted to the cleaning apparatus, facilitating disassembly and maintenance of the dust collection container 12, for example, the mounting member 123 may include a tongue, the mounting chamber 11 having a groove, and the tongue may be engaged with the groove to removably mount the mounting member 123 to the inner surface of the mounting chamber 11. In addition, the mounting member 123 is made of hard material, so that the mounting member is not easy to deform, and is stable after being mounted.

The soft dust bag 124 may be plastic, wool, cotton wool, non-woven fabric or any other material known in the art, and mainly uses the soft and easily deformable characteristic thereof, so that the dust bag 124 can "bulge" to effectively use the volume thereof.

Wherein, the dust collection container 12 can be made of degradable materials to realize recycling or natural degradation and reduce environmental pollution.

In some embodiments, the mounting 123 is an elongated shape having a length L and a width W. Such as rectangular or oval. The longitudinal direction of the mounting member 123 is the longitudinal direction of the dust container 12, and the width direction of the mounting member 123 is the height direction of the dust container 12. Illustratively, the second air inlet 121 and the second air outlet 120 are both disposed on the mounting member 123, and the second air inlet 121 and the second air outlet 120 are arranged along the length direction of the mounting member 123.

As shown in fig. 2A-3, in some embodiments, the second air inlet 121 is near a first end of the mounting member 123 in the length direction, and the second air outlet 120 is near a second end of the mounting member 123 in the length direction. As shown in fig. 5A to 6, the air with dust and other garbage can be sucked from one end of the dust collection container 12, and then drawn out from the other end of the dust collection container 12, and the air flow flows through both ends of the dust collection container 12 in the longitudinal direction, so that at least the air flow with dust can pass through each position of the dust collection container 12 in the longitudinal direction as much as possible, thereby making more sufficient use of the space in the dust bag 124 and improving the effective dust collection rate.

In some embodiments, as shown in fig. 1C, the first air intake 111 may be disposed near the top of the mounting chamber 11, i.e., the distance from the top of the first air intake 111 to the top of the mounting chamber 11 is less than the distance from the bottom of the first air intake 111 to the bottom of the mounting chamber 11. Illustratively, the bottom of the first air intake 111 may be 30mm from the bottom of the mounting chamber 11. Theoretically, the closer the first air inlet 111 is to the top of the installation chamber 11, i.e. the farther the first air inlet 111 is from the bottom of the installation chamber 11, the better the first air inlet 111 is from the bottom of the installation chamber 11, so that the risk of leakage of the garbage in the dust collecting container 12 from the first air inlet 111 can be reduced, and the effective usage volume of the dust collecting container 12 can be increased to some extent.

Of course, the first air outlet 112 may also be disposed near the top of the installation chamber 11, i.e., the distance from the top of the first air outlet 112 to the top of the installation chamber 11 is smaller than the distance from the bottom of the first air outlet 112 to the bottom of the installation chamber 11. It should be noted that, in the related art, once the garbage in the dust collecting container 12 leaks from the second air inlet 121, it is generally considered that the dust collecting space of the dust collecting container 12 is full, the user is prompted to replace the dust collecting container 12 or clean the dust collecting container 12, but there is a possibility that the space in the dust collecting container 12 remains in fact, so that the dust collecting space of the dust collecting container 12 is not fully utilized.

In the present application, since the air flow flows along the flow path shown in fig. 5A to 6, dust, hair, and other waste in the air flow can be orderly filled into the dust collection container from the second air outlet 120. In particular, when the dust bag 124 is an airtight dust bag and the dust collecting container 12 is only blown out through the second air outlet 120, dust, hair and other wastes in the air flow can be more effectively accumulated toward the second air outlet 120, and direct accumulation at the second air inlet 121 can be avoided as much as possible, compared with the form that all the air-permeable mesh portions of the entire air-permeable dust bag are used as the air outlets. And as shown in fig. 5A to 5C, the filter structure 122 is disposed at the second air outlet 120, or as shown in fig. 6, the filter structure 122 is disposed at the third air outlet 113, so that even if the garbage is deposited at the second air outlet 120, the garbage will not leak out of the dust collecting container 12 through the second air outlet 120 or the third air outlet 113, and therefore the garbage can be orderly deposited at all corners of the dust collecting container 12 from the second air outlet 120 to the direction of the second air inlet 121 as much as possible, thereby effectively utilizing the actual space of the dust collecting container 12, improving the dust collecting volume, and further reducing the frequency of discarding and maintaining the dust collecting container 12 by a user.

Of course, correspondingly, the first air inlet 111 may be near the first end of the installation cavity 11 in the length direction, and the first air outlet 112 may be near the second end of the installation cavity 11 in the length direction. For example, the first air inlet 111 and the first air outlet 112 are disposed on the same side wall of the installation chamber 11, and the second air inlet 121 and the second air outlet 120 are respectively disposed on the same side of the dust collecting container 12.

The second air inlet 121 and the second air outlet 120 of the dust collecting container 12 are arranged on the same side of the dust collecting container 12 and are positioned at two ends of the dust collecting container in the length direction, so that air with dust and other garbage can be sucked from one end of the dust collecting container in the length direction and is pumped out from the other end of the dust collecting container in the length direction after passing through the dust collecting container 12, and the dust, particles, hair and other garbage in the air can be filtered and left by the dust collecting container, so that the garbage can be filled in the dust collecting container from the end of the filtering structure, the dust collecting container is orderly filled, the space utilization rate of the dust collecting container is remarkably improved, and the garbage such as hair can be compressed along with the end of the second air outlet 120 at the downstream along with the action of air flow under the suction effect of vacuum negative pressure, so that the space utilization rate of the dust collecting container is further improved.

In some embodiments, as shown in fig. 2A and 2B, along the height direction of the dust collecting container 12 (as shown in the vertical direction of fig. 2A and 2B), the top of the second air inlet 121 is lower than the top of the second air outlet 120, and the bottom of the second air inlet 121 is higher than the bottom of the second air outlet 120. That is, the opening of the second air inlet 121 is narrower than the second air outlet 120. In this embodiment, the upper and lower boundaries of the second air inlet 121 are located entirely between the upper and lower boundaries of the second air outlet 120 along the height direction of the dust container 12.

Alternatively, along the height direction of the dust collection container 12, the top of the second air inlet 120 is higher than the top of the second air outlet 121, and the bottom of the second air inlet 120 is lower than the bottom of the second air outlet 121; that is, the opening of the second air outlet 120 is narrower than the second air inlet 121. In this embodiment, the upper and lower boundaries of the second air outlet 120 are located entirely between the upper and lower boundaries of the second air inlet 121 along the height direction of the dust container 12.

As shown in fig. 2C (the dotted arrow in the drawing is the airflow flow path shown), when the air with dust and other garbage is sucked into the second chamber 12C from the second air inlet 121 of the dust collecting container 12 under the negative pressure, the air is drawn out from the second air outlet 120 of the dust collecting container 12, and the width of the upper and lower sides of the second air outlet 120 exceeds the second air inlet 121, so that the airflow can fill the two sides of the second chamber 12C with the garbage, thereby fully utilizing the space above the dust collecting container 12 to fill the garbage. Similarly, when the widths of the upper and lower sides of the second air inlet 121 exceed the width of the second air outlet 120, the air flow can also carry the garbage to fill the two sides of the second cavity 12C in the height direction, so that the space above and below the dust collecting container 12 is fully utilized to fill the garbage.

It will be appreciated that in other embodiments, the second air inlet 121 and the second air outlet 120 may be only partially opposite to each other along the length direction of the dust collecting container 12, and the two may be staggered by a certain dimension along the height direction of the dust collecting container 12.

As shown in fig. 3, there is shown a dust collection container 12 different from that of fig. 2A to 2C in that the second air inlet 121 is offset downward with respect to the second air outlet 120 in the height direction of the dust collection container 12. Specifically, along the height direction of the dust collecting container 12, the top of the second air inlet 121 is lower than the top of the second air outlet 120 and higher than the bottom of the second air outlet 120, and the bottom of the second air inlet 121 is lower than the bottom of the second air outlet 120. That is, the second air inlet 121 partially overlaps the second air outlet 120 in the height direction of the dust container 12, the upper boundary of the second air inlet 121 is located between the upper and lower boundaries of the second air outlet 120, and the lower boundary of the second air inlet 121 is located below the lower boundary of the second air outlet 120. In this way, the air flow can also guide the garbage in the height direction of the second cavity 12C, and the space in the height direction of the second cavity 12C is fully utilized, so that the garbage can be filled in the second cavity 12C as much as possible, and the maximum utilization of the space in the dust bag 124 is realized.

In other embodiments, the second air inlet 121 may be upwardly offset from the second air outlet 120 along the height direction of the dust container 12. Specifically, along the height direction of the dust collecting container 12, the top of the second air inlet 121 is higher than the top of the second air outlet 120, and the bottom of the second air inlet 121 is lower than the top of the second air outlet 120 and higher than the bottom of the second air outlet 120. That is, the second air inlet 121 and the second air outlet 120 are still partially overlapped in the height direction of the dust container 12, but the lower boundary of the second air inlet 121 is located between the upper and lower boundaries of the second air outlet 120, and the upper boundary of the second air inlet 121 is located above the upper boundary of the second air outlet 120. In this way, the effect of guiding the air flow in the height direction of the second chamber 12C for the garbage can also be achieved, and the space in the height direction of the second chamber 12C can be fully utilized.

In some embodiments, as shown in fig. 2B, the centerline of the second air inlet 121 in the height direction of the dust collection container 12 substantially coincides with the centerline of the second air outlet 120 in the height direction of the dust collection container 12.

In other embodiments of the present application, at least one of the second air inlet 121 and the second air outlet 120 may be provided on the mounting member 123. For example, only one of the second air inlet 121 and the second air outlet 120 may be disposed on the mounting member 123, and the other of the two may be disposed on one side of the mounting member 123 in the length direction, for example, the second air inlet 121 may be disposed on the dust bag 124, the second air inlet 121 may be in sealing connection with the first air inlet 111, and the second air inlet 121 may be disposed side by side with the mounting member 123.

It will be appreciated that in other embodiments, the dust collecting container 12 may not include the mounting member 123, the dust collecting container 12 includes the flexible dust bag 124, and the second air inlet 121 and the second air outlet 120 are disposed on the dust bag 124. When the dust collection container 12 includes the mounting member 123 and the dust bag 124, the "height direction of the dust collection container 12" is understood to be the width W direction of the mounting member 123.

In some embodiments, as shown in fig. 4A, the dust bag 124 is made of an airtight material, for example, the dust bag 124 is made of an airtight film, the dust collecting container 12 is provided with a second air outlet 120 (as shown in fig. 4A), and the filtering structure 122 is mounted on the dust collecting container 12 and covers the second air outlet 120. Dust, particles, hair and other waste can enter the dust collection container 12 along with the airflow under the action of vacuum negative pressure, and the dust bag 124 is orderly filled after being filtered by the filtering structure 122. In fig. 4A, in the process of collecting the garbage, the garbage in the dust bag 124 enters from right to left under the action of the suction force at the second air outlet 120, and fills from left to right in sequence until the dust bag 124 is fully filled with the garbage, and the garbage is filled to be close to the second air inlet 121. The dust bag structure of airtight material can avoid the dust in the air to get into installation cavity 11, guarantees the cleanness in the installation cavity 11, and also can reduce the risk that moisture etc. in the installation cavity 11 gets into in the dust bag.

In one embodiment, when the filter structure 122 covers the second air outlet 120, the area of the second air outlet 120 may be set to be larger than the area of the second air inlet 121. For example, the area of the second air outlet 120 is 2 to 5 times the area of the second air inlet 121. In this manner, the filter structure 122 may be made as large and thin as possible, where "thin" is to make the filter structure 122 occupy as little volume of the dust bag as possible, thereby avoiding taking up more dust bag space, further increasing the effective usage volume of the dust bag, and "large" is to make the filter structure 122 have better guaranteed filtering effect, and may make the service time of the filter structure 122 longer. In addition, because the second air inlet 121 can be made smaller, the air flow rate of the second air inlet 121 is larger under the same working power of the cleaning equipment, the cleaning equipment is more beneficial to sucking clustered garbage, and the garbage collection effect of the cleaning robot is improved.

In some embodiments, the area of the first air outlet 112 may be smaller than that of the second air outlet 120, the larger filtering structure 122 filters the garbage to ensure the filtering effect, and through the smaller first air outlet 112, the air flow rate is further increased in the process of flowing out from the second air outlet 120 to the first air outlet 112, so that the dust collection effect of the cleaning robot is better under the same working power. In other embodiments, the shape of the first air outlet 112 may match the shape of the second air outlet 120, e.g., both profiles may be square, circular, trapezoidal, etc., and the size of the first air outlet 112 may match the size of the second air outlet 120.

When the dust bag 124 is made of an airtight material, as in fig. 4A, the dust bag 124 is airtight except for the filter structure 122. Under the action of the negative pressure device, the air with garbage is sucked into the second cavity 12C from the first air inlet 111 and the second air inlet 121, the air filtered by the filtering structure 122 is pumped out from the first air outlet 112, meanwhile, the air between the dust bag 124 and the installation cavity 11 is pumped out from the first air outlet 112, the rising speed of the dust bag 124 can be accelerated by the dust bag 124 made of airtight materials, and after the dust bag 124 is completely raised, the dust bag 124 always keeps in an expanded state along with the air suction of the negative pressure device, so that the dust bag 124 can be ensured to have a larger effective volume. In addition, when the dust bag 124 made of airtight materials is adopted, compared with the dust bag 124 made of airtight materials, the dust bag 124 can be fully bulged by adopting a negative pressure device with smaller power, so that energy sources and cost are saved, and noise can be slightly reduced.

In another embodiment, as shown in fig. 4C, unlike fig. 4A, the dust bag 124 may be made of a breathable material with a certain air resistance, such as a non-woven fabric material, and the dust bag 124 itself may filter the air mixed with garbage entering from the second air inlet 121. Illustratively, the filter structure 122 is made of a HEPA paper, the dust bag 124 is made of a non-woven fabric, and the filter structure 122 has a better filtering effect than the dust bag 124.

In this way, a slightly breathable space is formed between the dust bag 124 and the installation cavity 11, under the action of the negative pressure device, the air with garbage is sucked into the second cavity 12C from the first air inlet 111 and the second air inlet 121, the air filtered by the dust bag 124 and the filtering structure 122 is pumped out from all directions to the first cavity 11C, meanwhile, the air between the dust bag 124 and the installation cavity 11 is pumped out, because the dust bag 124 and the filtering structure 122 have certain air permeation resistance, the air flow rate between the dust bag 124 and the installation cavity 11 is faster, the flow rate pumped out from the second air outlet 120 is smaller than the flow rate pumped out from the dust bag 124 and the installation cavity 11, the dust bag 124 can be gradually swelled, and along with the pumping of the negative pressure device, the dust bag 124 can also keep an expanded state, and the dust bag 124 can be ensured to have a larger effective volume.

It should be noted that, in some embodiments, the dust bag 124 may be cleaned after "bulge", and during the cleaning operation, the negative pressure device draws negative pressure into the dust bag 124 and also draws negative pressure into the installation chamber 11, but due to the pressure difference, the dust bag 124 may be always in a "bulge" state, so that the dust bag 124 may have a larger effective volume in the process of ensuring normal dust collection.

In yet another embodiment, as shown in fig. 4B, unlike fig. 4A, the dust bag 124 is made of a breathable material, for example, the dust bag 124 is made of a non-woven fabric, so that the additional filtering structure 122 can be omitted, and the dust bag 124 itself can serve as the filtering structure 122 to filter the air mixed with garbage entering the dust bag 124.

In some embodiments, the dust bag 124 may initially be in a collapsed state for ease of transportation and storage. Specifically, at least a portion of the dust bag 124 is in a folded configuration to enable the dust bag 124 to be switched between a folded state and an unfolded state. As shown in fig. 7-12, a dust collection container 12 is shown with a dust bag 124 that is collapsible.

As shown in fig. 7 and 8, the dust collection container 12 has a first direction X and a second direction Y, and the first direction X is perpendicular to the second direction Y. The first direction X corresponds to the width direction of the folded dust bag 124 and the second direction Y corresponds to the length direction of the folded dust bag 124. As shown in fig. 8, in a first direction X of the dust bag 124, both sides X1, X2 of the dust bag 124 are respectively folded inwardly in a zigzag folding manner, such that the dust bag 124 forms opposite first and second folds 1241, 1242, and a face layer 1243 connecting the first and second folds 1241, 1242, the first fold 1241 comprising a first fold 12411 and a second fold 12412, and the second fold 1242 comprising a third fold 12421, 12422. Facing 1243 connects the opposing first and second folds 1241, 1242 together, which enclose a space within dust bag 124.

As shown in fig. 8, in the folded state, the facing layer 1243, the first folded layer 12411 and the second folded layer 12412 are sequentially stacked, and the facing layer 1243, the third folded layer 12421 and the fourth folded layer 12422 are sequentially stacked, so that the dust bag 124 may be more regular and have a smaller volume in the folded state.

As shown in connection with fig. 7, 9-10, in the second direction Y of the dust bag 124, a first end of the face layer 1243 (e.g., the left end of fig. 11), a first end of the first fold layer 12411, and a first end of the second fold layer 12412 are bonded together, and a second end of the face layer 1243 (e.g., the right end of fig. 11), a second end of the first fold layer 12411, and a second end of the second fold layer 12412 are bonded together, to construct the dust bag 124.

In some embodiments, as shown in fig. 8, the first fold 1241 and the second fold 1242 are at least partially stacked in the folded state of the dust bag 124. The first and second folds 1241, 1242 are partially stacked with each other, which is advantageous in reducing the width of the dust bag 124 when folded, i.e., the dimension in the first direction X, and thus, the dust bag 124 in the folded state is smaller in volume, and more convenient to store and transport.

In some embodiments, the dust collection container 12 includes a rigid mounting 123 and a flexible dust bag 124, and the dust collection container 12 is removably connected to the mounting chamber 11 by the mounting 123. The dust container 12 may be a disposable consumable, and the dust bag 124 may be recycled with the mounting member 123 after use.

As shown in fig. 7, 9, 11, and 12, illustratively, in the second direction Y of the dust bag 124, the length of the dust bag 124 is greater than the length of the mounting member 123, and both ends of the dust bag 124 protrude beyond the mounting member 123 to form a first excess 1231 and a second excess 1232, respectively. In this way, the dust bag 124 is longer than the length of the two ends of the mounting member 123 and can be matched as much as possible to the size and shape of the mounting chamber 11 after deployment.

As shown in fig. 9 and 10, in the folded state of the dust bag 124, the first and second excess sections 1231 and 1232 are folded in a relatively close direction and are partially bonded to the surface of the facing 1243, respectively. Thereby avoiding the first excess 1231 and the second excess 1232 from unraveling, affecting the footprint of the dust bag 124; with the dust bag 124 in the expanded state, the first and second excess segments 1231, 1232 are disengaged from the surface of the face layer 1243. When the dust collecting container 12 is engaged with the mounting chamber 11, if the first and second protruding sections 1231 and 1232 are in a free state, the first and second protruding sections 1231 and 1232 are easily engaged with the corresponding mounting grooves of the mounting chamber 11, and the dust bag 124 is easily pulled and punctured by accident during the process of engaging the mounting member 123 of the dust collecting container 12 with the mounting chamber 11. Therefore, in the initial folded state of the dust bag 124, the first and second protruding sections 1231 and 1232 are combined with the surface layer 1243, so that the dust bag 124 can be effectively prevented from being damaged during the process of installing the dust container 12.

Illustratively, the surfaces of the first and second excess segments 1231, 1232 facing away from the mounting member 123 are provided with adhesive portions P (see fig. 10), and in the folded state, the first and second excess segments 1231, 1232 are respectively folded away from the mounting member 123 and then adhered to the surface of the facing layer 1243 facing away from the mounting member 123. The adhesive portion P may be double-sided adhesive tape or dispensing. It will be appreciated that adhesive P may also be provided on the surface of facing 1243 facing away from mounting member 123; alternatively, in other embodiments, the adhesive portion P may be replaced by a hook and loop or a hidden hook.

When the dust bag 124 is folded, the first folded portion 1241 and the second folded portion 1242 on both sides of the first direction X are respectively folded, so that the first folded layer 12411 and the second folded layer 12412 are stacked face to face, the third folded layer 12421 and the fourth folded layer 12422 are stacked face to face, and are respectively stacked on both sides of the surface layer 1243 in the first direction X, and the first protruding section 1231 and the second protruding section 1232 on both ends of the second direction Y are folded back to the mounting member 123 and then are combined on the surface of the surface layer 1243. In this way, the size of the folded dust bag 124 may be reduced in the length and width directions, and a rectangle (see fig. 7) may be formed that substantially matches the size of the mounting member 123.

Fig. 13 shows a schematic view of a process in which the dust bag 124 is inflated by the negative pressure device by drawing negative pressure after the dust bag 124 is mounted to the mounting chamber 11 in an initially folded state, and fig. 13 shows that the dust bag 124 can be sufficiently attached to the mounting chamber 11 after being inflated, so that the effective volume of the dust bag 124 is as large as possible.

In the initially installed state, the dust bag 124 is in a fully folded state, i.e., in a first direction X of the dust bag 124, both sides X1, X2 of the dust bag 124 are respectively folded inwardly in a zigzag-folded manner, the facing layer 1243, the first folded layer 12411 and the second folded layer 12412 are sequentially stacked, and the facing layer 1243, the third folded layer 12421 and the fourth folded layer 12422 are sequentially stacked, the dust bag 124 having a dimension, i.e., a width, substantially identical to the mounting member 123 in the first direction X; in the second direction Y of the dust bag 124, the dust bag 124 may be fixed to the surface of the facing layer 1243 facing away from the mounting member 123 by the first and second protruding sections 1231 and 1232, respectively, at both ends thereof through the adhesive portion P thereon, and the dust bag 124 may have a size, i.e., a length, substantially identical to the mounting member 123 in the second direction Y.

During the process of swelling the dust bag 124, air between the dust bag 124 and the installation cavity 11 is gradually extracted, the dust bag 124 can be gradually swelled under the negative pressure, the first excess section 1231 and the second excess section 1232 are separated from the surface layer 1243 and are unfolded towards the two ends of the dust bag 124 in the length direction, meanwhile, the first folding layer 12411 and the second folding layer 12412, the third folding layer 12421 and the fourth folding layer 12422 on the two sides of the dust bag 124 are gradually unfolded, and the volume of the dust bag 124 is gradually increased; finally, the volume in the dust bag 124 bulges to the maximum, the dust bag 124 fills the whole first cavity 11C, and is attached to the inner wall of the installation cavity 11, and then the state of negative pressure pumping is continuously maintained, so that the dust bag 124 can always maintain the bulge state, and the effective use volume of the dust bag 124 is ensured to be maximized.
