[0030] The present application is further described below in combination with Figures 1-5.

[0031] Referring to Figures 1 and 2, the dust collecting station according to the first aspect of the present application comprises a mounting chamber 100, a first cavity 110 is formed inside the mounting chamber 100, the mounting chamber 100 is provided with a first air inlet 120 and a first air outlet 130 communicating with the first cavity 110, and the first air inlet 120 and the first air outlet 130 are respectively located on two sides of the mounting chamber 100. Specifically, the first air inlet 120 is located on the upper side of the mounting chamber 100, and the first air outlet 130 is located on the lower side of the mounting chamber 100. In some other embodiments, the first air inlet 120 and the first air outlet 130 can also be located on the adjacent two sides of the mounting chamber 100.

[0032] It can be understood that in some embodiments of the first aspect of the present application, referring to Figures 1 and 2, the dust collecting station comprises a mounting bracket 200 and a dust collecting container, the mounting bracket 200 is movably arranged in the first cavity 110, and the mounting bracket 200 is used to fix the dust collecting container and the mounting chamber 100.

[0033] It can be understood that, in some embodiments of the first aspect of the present application, referring to Figures 1 and 2, the dust collecting container comprises the mounting plate 320 and the dust bag 310, which can be a disposable dust bag 310 and can be directly discarded after being used for a period of time. The dust bag 310 is internally formed with a second cavity 311 for collecting garbage, and the dust collecting container has a second air inlet 321 communicating with the second cavity 311, which is used to be in communication with the first air inlet 120, so that the garbage can enter the dust bag 310 through the first air inlet 120 and the second air inlet 321 in turn and be collected by the dust bag 310. In some embodiments, referring to Figures 1 and 2, the second air inlet 321 is formed in the mounting plate 320, and the dust bag 310 is sleeved on the mounting plate 320, so that after the mounting bracket 200 and the mounting chamber 100 are fixed, the first air inlet 120 and the second air inlet 321 are in communication, and thus the first air inlet 120 and the second cavity 311 are in communication.

[0034] In some embodiments, referring to Figures 2 and 3, the mounting plate 320 is detachably fixed to the mounting bracket 200. When dust collection is needed, the mounting plate 320 is mounted on the mounting bracket 200 to fix the mounting bracket 200 and the dust collecting container, so as to fix the dust collecting container and the mounting chamber 100. When the dust bag 310 needs to be replaced, the mounting bracket 200 is taken out of the mounting chamber 100, and then the mounting plate 320 is detached from the mounting bracket 200, so that the dust bag 310 can be replaced.

[0035] It can be understood that, in some embodiments of the first aspect of the present application, referring to Figures 1 and 2, the dust bag 310 is made of a breathable material, such as a sewn fabric bag, a non-woven fabric bag, an SMS fabric bag (Spunbond-Meltblown-Spunbond), a paper bag, etc. The dust bag 310 has a plurality of breathable mesh holes 312, so that the airflow entering the second cavity 311 through the first air inlet 120 and the second air inlet 321 can enter the first cavity 110 through the breathable mesh holes 312 and be discharged through the first air outlet 130.

[0036] In some embodiments, referring to Figures 1 and 2, along the length direction of the mounting bracket 200, one side of the mounting plate 320 is obliquely arranged towards the center of the first cavity 110. The gravity of the dust bag 310 is concentrated on the side of the mounting plate 320 where the position is lower, so that the side of the dust bag 310 where the position is higher is more easily unfolded, thereby facilitating to increase the volume of the dust bag 310 and improve the utilization rate of the dust bag 310. At the same time, the dust bag 310 can be fully unfolded when being placed in the first cavity 110 in the related art, without being folded, so as to effectively utilize the volume of the dust bag 310 and improve the utilization rate of the dust bag 310.

[0037] It can be understood that, in some embodiments of the first aspect of the present application, referring to FIGS. 2 and 4, the dust collecting station comprises a negative pressure device 400, which is in fluid communication with the first air outlet 130, and is used at least for pumping the first cavity 110 to make the air pressure in the first cavity 110 lower than the air pressure in the second cavity 311. When it is necessary to unfold the dust bag 310, the negative pressure device 400 pumps the first cavity 110, so that the air flow enters the second cavity 311 through the first air inlet 120 and the second air inlet 321 in turn, and then enters the first cavity 110 through the air-permeable mesh 312, and then enters the negative pressure device 400 from the first air outlet 130; because the air pressure in the first cavity 110 is lower than the air pressure in the second cavity 311 at this time, the dust bag 310 is driven to swell, so that the dust bag 310 is gradually unfolded to increase the volume of the dust bag 310, thereby improving the utilization rate of the dust bag 310. At the same time, when the negative pressure device 400 pumps, the garbage can flow through the first air inlet and the second air inlet into the second cavity 311 in turn, so as to be collected by the dust bag 310, and the garbage entering the dust bag 310 further exerts force on the dust bag 310 under the action of gravity, so that the dust bag 310 is further unfolded in the up-down direction, further improving the utilization rate of the dust bag 310.

[0038] It can be understood that, in some embodiments of the first aspect of the present application, referring to FIGS. 2 and 4, a filtering device is arranged at the first air outlet 130, and the filtering device is used for filtering the air flow at the first air outlet 130 to reduce the situation that small particles and other garbage enter the negative pressure device 400. Specifically, the filtering device can be a filter 1311, when the negative pressure device 400 continuously pumps, the garbage flows through the first air inlet and the second air inlet into the second cavity 311 in turn, at this time, part of the small particles or dust can pass through the air-permeable mesh 312 with the air flow, and then be transmitted to the first air outlet 130, the air flow is filtered by the filter 1311 to separate the air flow from the small particles, thereby reducing the situation that small particles and other garbage enter the negative pressure device 400, so that the negative pressure device 400 is protected.

[0039] It can be understood that, in some embodiments of the first aspect of the present application, referring to FIGS. 2 and 4, the first air inlet 120 is arranged obliquely towards the direction away from the first air outlet 130, so that when the negative pressure device 400 draws air, the air flow passing through the first air inlet 120 and the second air inlet 321 is towards the directions of the first and second positions of the dust bag 310 on the left and right sides of the first air outlet 130, i.e. the air flow entering the dust bag 310 blows towards the first position of the dust bag 310 to exert a pushing force on the first position of the dust bag 310, while the first air outlet 130 draws air close to the second position of the dust bag 310 to exert a suction force on the second position of the dust bag 310 when the negative pressure device 400 draws air, so that under the driving of the two forces, the dust bag 310 is more easily unfolded. It should be noted that, in the present embodiment, referring to FIGS. 2 and 4, the first and second positions are respectively on the left and right sides of the dust bag 310, so that under the driving of the two forces, the left and right sides of the dust bag 310 are pulled apart, further driving the dust bag 310 to be fully unfolded.

[0040] It can be understood that, in some embodiments of the first aspect of the present application, referring to FIGS. 2 and 4, the positions of the first air inlet 120 and the first air outlet 130 are arranged staggered in the horizontal direction, so that when the negative pressure device 400 draws air, the air flow passing through the first air inlet 120 and the second air inlet 321 flows to the first air outlet 130 along the left and right directions at a longer distance. Since the air flow continuously exerts a force on the dust bag 310 in the process of passing through the gas permeable mesh 312, the dust bag 310 is constantly unfolded, and the longer distance of the air flow flowing along the left and right directions increases the angle of the unfolding of the left and right sides of the dust bag 310, further driving the dust bag 310 to fill the first cavity 110 and improving the utilization rate of the dust bag 310. At the same time, when the negative pressure device 400 draws air, the garbage can flow through the first air inlet and the second air inlet in sequence to reach the second cavity 311, so as to be collected by the dust bag 310, and the garbage entering the dust bag 310 falls to the bottom of the dust bag 310 under the action of gravity, at which time the position of the garbage exerting gravity on the dust bag 310 and the position of the first air outlet 130 are respectively on the left and right sides of the first cavity 110, so as to further unfold the dust bag 310 in the left and right directions, further improving the utilization rate of the dust bag 310.

In some embodiments, referring to FIGS. 2 and 4, one end of the air guide pipe 500 close to the dust collecting container is obliquely arranged towards the direction away from the first air outlet 130, which makes the airflow in the air guide pipe 500 obliquely arranged towards the direction away from the first air outlet 130 after entering the dust bag 310 through the second air inlet, so that the left and right sides of the dust bag 310 are pulled apart, and the dust bag 310 is further fully unfolded.

[0042] It can be understood that, in some embodiments of the first aspect of the present application, referring to FIGS. 2 and 4, one end of the air guide pipe 500 close to the mounting bracket 200 is perpendicular to the mounting plate 320, so that the direction of the first air inlet 120 is perpendicular to the mounting plate 320, and at this time, the caliber of the first air inlet 120 is increased, so that the air volume of the first air inlet 120 is increased, that is, the force of the airflow entering the dust bag 310 on one side of the dust bag 310 is increased, which is further beneficial to the left and right sides of the dust bag 310 being pulled apart and the dust bag 310 being fully unfolded.

At the same time, when the negative pressure device 400 exhausts, the garbage can flow through the first air inlet and the second air inlet into the second cavity 311 in sequence, so as to be collected by the dust bag 310, and the garbage entering the dust bag 310 further exerts force on the dust bag 310 under the action of gravity, so that the dust bag 310 is further expanded in the up-down direction, and the utilization rate of the dust bag 310 is further improved.

[0053] The second aspect embodiment of the application provides a cleaning device, which comprises the dust collecting station of the first aspect embodiment of the application. The cleaning device further comprises a dust storage container, which can be applied to a dust collector, a sweeping robot or the like to store garbage sucked by the device.

[0054] The dust storage container is provided with a dust outlet, and the dust outlet is in communication with the first air inlet 120. When the garbage in the dust storage container needs to be collected, the negative pressure device 400 is used to exhaust, so that the garbage can flow through the dust outlet, the first air inlet and the second air inlet into the second cavity 311 in sequence, and then be collected by the dust bag 310.

[0055] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
