[0002] When a bag-type vacuum cleaner is working, the dust bag of the dust collection station collects dust, large particles of debris and other garbage. The dust bag is usually installed horizontally in a compact space. The dust bag is also folded, so that the dust bag cannot be fully unfolded after being installed in the dust collection station.

[0003] In the related art, in order to solve the above problems, a negative pressure device is usually provided in the dust collecting station, through which the internal installation space of the dust collecting station is evacuated to form a negative pressure state in the internal installation space, thereby driving the dust bag to fully unfold.

[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] Reference Figure 1 and Figure 2 The embodiment of the first aspect of the utility model provides a dust collection station, including an installation chamber 100, a first chamber 110 is formed inside the installation chamber 100, and the installation chamber 100 is provided with a first air inlet 120 and a first air outlet 130 connected to the first chamber 110, and the first air inlet 120 and the first air outlet 130 are respectively located on both sides of the installation chamber 100. Specifically, the first air inlet 120 is located on the upper side of the installation chamber 100, and the first air outlet 130 is located on the lower side of the installation chamber 100. In some other embodiments, the first air inlet 120 and the first air outlet 130 can also be located on two adjacent sides of the installation chamber 100.

[0039] It is understandable that in some embodiments of the first aspect of the present utility model, reference Figure 1 and Figure 2 The dust collection station includes a mounting bracket 200 and a dust collection container. The mounting bracket 200 is movably disposed in the first cavity 110 , and the mounting bracket 200 is used to fix the dust collection container to the mounting chamber 100 .

[0040] It is understandable that in some embodiments of the first aspect of the present utility model, reference Figure 1 and Figure 2 The dust collection container includes a mounting plate 320 and a dust bag 310. The dust bag 310 can be a disposable dust bag 310 that can be directly discarded after a period of use. A second cavity 311 for collecting garbage is formed inside the dust bag 310. The dust collection container has a second air inlet 321 connected to the second cavity 311. The second air inlet 321 is used to connect with the first air inlet 120, so that garbage can enter the dust bag 310 through the first air inlet 120 and the second air inlet 321 in turn, and then be collected by the dust bag 310. In some embodiments, refer to Figure 1 and Figure 2 The second air inlet 321 is opened on 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 connected and connected, so that the first air inlet 120 and the second chamber 311 are connected.

[0041] In some embodiments, reference Figure 2 and Figure 3 The mounting plate 320 is detachably fixed to the mounting bracket 200. When dust collection is required, the mounting plate 320 is installed on the mounting bracket 200 to fix the mounting bracket 200 to the dust collecting container, thereby fixing the dust collecting container to 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 separated from the mounting bracket 200, so as to replace the dust bag 310.

[0042] It is understandable that in some embodiments of the first aspect of the present utility model, reference Figure 1 and Figure 2 The dust bag 310 is made of a breathable material, such as a sewing bag, a non-woven bag, an SMS bag (Spunbond-Meltblown-Spunbond, composite non-woven fabric), a paper bag, etc. The dust bag 310 has a plurality of breathable mesh holes 312, so that the airflow reaching 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 then be discharged through the first air outlet 130.

[0043] In some embodiments, reference Figure 1 and Figure 2Along the length direction of the mounting bracket 200, one side of the mounting plate 320 is inclined toward the center of the first cavity 110, and the gravity of the dust bag 310 is focused on the lower side of the mounting plate 320, making it easier to unfold the higher side of the dust bag 310, thereby facilitating increasing the volume of the dust bag 310 and improving the utilization rate of the dust bag 310; at the same time, the dust bag 310 in the related art can be fully unfolded when placed in the first cavity 110 without folding, thereby effectively utilizing the volume of the dust bag 310 and improving the utilization rate of the dust bag 310.

[0044] It is understandable that in some embodiments of the first aspect of the present utility model, reference Figure 2 and Figure 4 The dust collecting station includes a negative pressure device 400, which is in fluid communication with the first air outlet 130. The negative pressure device 400 is at least used to evacuate the first cavity 110 so that the air pressure in the first cavity 110 is lower than the air pressure in the second cavity 311. When the dust bag 310 needs to be unfolded, the negative pressure device 400 evacuates the first cavity 110, so that the airflow enters the second cavity 311 through the first air inlet 120 and the second air inlet 321 in sequence, and then the airflow 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; since 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 is evacuating air, the garbage can pass through the first air inlet and the second air inlet in sequence with the flow of air flow to reach the second cavity 311, so as to be collected by the dust bag 310. The garbage entering the dust bag 310 further exerts a force on the dust bag 310 under the action of gravity, so that the dust bag 310 is further expanded in the up and down directions, thereby further improving the utilization rate of the dust bag 310.

[0045] It is understandable that in some embodiments of the first aspect of the present utility model, reference Figure 2 and Figure 4 , a filter device is provided at the first air outlet 130, and the filter device is used to filter the airflow at the first air outlet 130 to reduce the situation where fine particles and other garbage enter the negative pressure device 400. Specifically, the filter device can be a filter 1311. When the negative pressure device 400 continues to pump air, the garbage passes through the first air inlet and the second air inlet in sequence with the airflow to reach the second cavity 311. At this time, some fine particles or dust will pass through the air permeable mesh 312 with the airflow, and thus be transferred to the first air outlet 130. The airflow is filtered by the filter 1311 to separate the airflow from the fine particles, thereby reducing the situation where fine particles and other garbage enter the negative pressure device 400, so that the negative pressure device 400 is protected.

[0046] It is understandable that in some embodiments of the first aspect of the present utility model, reference Figure 2 and Figure 4 , the first air inlet 120 is tilted in a direction away from the first air outlet 130, so that when the negative pressure device 400 is exhausting air, the airflow passing through the first air inlet 120 and the second air inlet 321 is located on both sides of the dust bag 310 in the direction of the first air outlet 130, that is, the airflow entering the dust bag 310 blows toward the first position of the dust bag 310 to apply a thrust to the first position of the dust bag 310, and when the negative pressure device 400 is exhausting air, the first air outlet 130 sucks the second position close to the dust bag 310 to apply a suction force to the second position of the dust bag 310, so that the dust bag 310 is more easily unfolded under the driving of the two forces. It should be noted that in this embodiment, referring to Figure 2 and Figure 4 The first position and the second position are respectively located 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.

[0047] It is understandable that in some embodiments of the first aspect of the present utility model, reference Figure 2 and Figure 4 The position of the first air inlet 120 and the position of the first air outlet 130 are staggered in the horizontal direction, so that when the negative pressure device 400 is exhausting air, the distance along the left-right direction of the airflow passing through the first air inlet 120 and the second air inlet 321 to the first air outlet 130 becomes longer. Since the airflow continuously exerts a force on the dust bag 310 in the process of passing through the breathable mesh 312, the dust bag 310 is continuously expanded, and the distance of the airflow flowing in the left-right direction becomes longer, so that the expansion angle of both sides of the dust bag 310 is increased, so as to further drive the dust bag 310 to fill the first cavity 110, thereby improving the utilization rate of the dust bag 310. At the same time, when the negative pressure device 400 is evacuating air, the garbage can pass through the first air inlet and the second air inlet in sequence with the flow of air flow to reach the second cavity 311, and is thus collected by the dust bag 310. The garbage entering the dust bag 310 falls to the bottom of the dust bag 310 under the action of gravity. At this time, the position where the garbage exerts gravity on the dust bag 310 and the position of the first air outlet 130 are respectively located on the left and right sides of the first cavity 110, thereby further expanding the dust bag 310 in the left and right directions, further improving the utilization rate of the dust bag 310.

[0048] It is understandable that in some embodiments of the first aspect of the present utility model, reference Figure 2 and Figure 4The dust collecting station includes an air duct 500, the first air inlet 120 is disposed in the air duct 500, and the air duct 500 is used to guide the direction of the first air inlet 120 and to convey the garbage, so that during the process of the negative pressure device 400 exhausting air, the air duct 500 can guide the garbage, so that the garbage passes through the first air inlet 120 and the second air inlet 321 in sequence and enters the second chamber 311. In some embodiments, referring to Figure 2 and Figure 4 The end of the air duct 500 close to the dust collecting container is tilted toward the direction away from the first air outlet 130, so that the airflow in the air duct 500 enters the dust bag 310 through the second air inlet and is tilted toward the direction away from the first air outlet 130, so that the left and right sides of the dust bag 310 are pulled apart, further driving the dust bag 310 to be fully unfolded.

[0049] It is understandable that in some embodiments of the first aspect of the present utility model, reference Figure 2 and Figure 4 , one end of the air duct 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. At this time, the diameter 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 conducive to the left and right sides of the dust bag 310 being pulled apart, driving the dust bag 310 to be fully unfolded.

[0050] It is understandable that in some embodiments of the first aspect of the present utility model, reference Figure 2 and Figure 3 , the air duct 500 and the dust collection container are sealed by a first sealing member. Specifically, the first sealing member includes a sealing ring 610, which is fixedly sleeved on one end of the air duct 500 close to the dust collection container. When the mounting bracket 200 is fixed to the dust collection container, the mounting bracket 200 is fixed to the mounting chamber 100, and the air duct 500 is connected to the second air inlet 321, and the gap between the first air inlet 120 and the second air inlet 321 is sealed by the sealing ring 610.

[0051] It is understandable that in some embodiments of the first aspect of the present utility model, reference Figure 3 and Figure 5, mounting grooves 220 are provided on both sides of the mounting bracket 200 in the length direction, and the openings of the mounting grooves 220 on both sides are arranged opposite to each other, and the mounting plate 320 is inserted into the mounting groove 220. When dust collection is required, the mounting plate 320 is inserted into the mounting groove 220 to fix the mounting plate 320 to the mounting bracket 200, thereby fixing the mounting bracket 200 to the mounting chamber 100, so that the air guide 500 is connected to the mounting plate 320, so that the first air inlet 120 and the second air inlet 321 are connected and connected; 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 groove 220, so that the dust bag 310 can be replaced.

[0052] It is understandable that in some embodiments of the first aspect of the present utility model, reference Figure 3 and Figure 5 The mounting bracket 200 is fixed to the mounting plate 320 by a snap-fit ​​structure 230. The snap-fit ​​structure 230 is movably arranged on the mounting bracket 200. When the mounting plate 320 is inserted into the plug-in slot, the snap-fit ​​structure 230 can fix the mounting bracket 200 and the mounting plate 320 to limit the relative position between the mounting plate 320 and the mounting bracket 200. When the dust bag 310 needs to be replaced, the snap-fit ​​structure 230 is separated from the mounting plate 320, and the mounting plate 320 is separated from the mounting slot 220, so that the dust bag 310 can be replaced.

[0053] It is understandable that in some embodiments of the first aspect of the present utility model, reference Figure 2 and Figure 3 The dust collection station includes a guide structure 700, which is arranged on the side wall of the first cavity 110. The guide structure 700 is used to guide the installation bracket 200 to enter the first cavity 110 to ensure that the air duct 500 can be connected to the installation plate 320 after the installation bracket 200 enters the first cavity 110, so that the first air inlet 120 and the second air inlet 321 are connected and connected. Specifically, the guide structure 700 is a guide groove opened on the side wall of the first cavity 110. There are two guide grooves, which are respectively located on two opposite side walls of the first cavity 110. Two guide parts 210 are respectively provided on both sides of the mounting bracket 200 in a one-to-one manner. The guide part 210 slides with the guide groove. The mounting bracket 200 is installed in the mounting chamber 100 by sliding with the guide groove. When the guide part 210 slides relative to the guide groove until the guide part 210 abuts against the bottom of the guide groove, the guide tube is connected to the mounting plate 320, thereby making the first air inlet 120 and the second air inlet 321 docked and connected.

[0054] It can be understood that in some other embodiments, the guide structure 700 can also be two guide rails, which are respectively located on two opposite side walls of the first cavity 110, and the guide portion 210 slides with the guide rails to install the mounting bracket 200 in the mounting chamber 100 through the sliding of the guide portion 210 and the guide rails, so that the guide tube is connected to the mounting plate 320, and the first air inlet 120 is connected to the second air inlet 321.

[0055] It is understandable that in some embodiments of the first aspect of the present utility model, reference Figure 2 and Figure 3 The guide structure 700 includes an arcuate portion 710 and a straight portion 720. The arcuate portion 710 is located below the straight portion 720. Since the loading and mounting bracket 200 is operated in a narrow space, the user usually operates without vision. Therefore, by setting the arcuate portion 710 and the straight portion 720, when loading and mounting the bracket 200, one end of the guide portion 210 is first carried on the arcuate portion 710, and the two slide relative to each other. With the guidance of the arcuate portion 710, the guide portion 210 is guided to the straight portion 720, thereby sliding relative to the straight portion to complete the installation of the mounting bracket 200, thereby improving the accuracy and convenience of loading.

[0056] It is understandable that in some embodiments of the first aspect of the present utility model, reference Figure 2 and Figure 3 The dust collecting station includes a dust chamber cover assembly 800. The installation chamber 100 is provided with an installation opening 140. The installation opening 140 is used for the installation bracket 200 to enter the first chamber 110. The dust chamber cover assembly 800 is used to close the installation opening 140. When the installation bracket 200 needs to be loaded, the dust chamber cover assembly 800 is opened, and the installation bracket 200 enters the first chamber 110 from the installation opening 140. The installation bracket 200 is installed in the installation chamber 100 by sliding through the guide portion 210 and the guide groove, so that the dust chamber cover assembly 800 closes the installation opening 140. In this embodiment, referring to Figure 2 and Figure 3 The installation opening 140 is opened on the left side of the installation chamber 100 , that is, the side of the installation plate 320 that is higher than the installation chamber 100 , so as to facilitate the installation of the installation bracket 200 .

[0057] It is understandable that in some embodiments of the first aspect of the present utility model, reference Figure 2 and Figure 3The dust chamber cover assembly 800 is sealed with the installation chamber 100 by the second sealing member 900, and the second sealing member 900 is arranged at the installation opening 140. When the dust chamber cover assembly 800 closes the installation opening 140, the airflow of the first chamber 110 will not leak out through the installation opening 140 through the sealing of the second sealing member 900, so that when the negative pressure device 400 draws air, the negative pressure state is formed in the first chamber 110 better, so that the dust bag 310 is better deployed.

[0058] The implementation principle of the first aspect of the present application is as follows: when installing the dust bag 310, the mounting plate 320 is inserted into the mounting groove 220, and the mounting bracket 200 is fixed to the mounting plate 320 by the snap structure 230, so that one end of the guide portion 210 is carried on the arc portion 710, and the two slide relative to each other, and the guide portion 210 is guided to the straight portion 720 by the guidance of the arc portion 710, so that it slides relative to the straight portion, so that the mounting bracket 200 is fixed to the mounting chamber 100, and then the air duct 500 is connected to the mounting plate 320. Then, the first air inlet 120 is connected to the second air inlet 321; at this time, along the length direction of the mounting bracket 200, one side of the mounting plate 320 is inclined toward the center of the first cavity 110, and the angle of the dust bag 310 in the first cavity 110 is adjusted so that the first cavity 110 can completely accommodate the dust bag 310, and then the first cavity 110 is evacuated by the negative pressure device 400, so that the first cavity 110 forms a negative pressure state, driving the dust bag 310 to be fully expanded, effectively utilizing the volume of the first cavity 110, and improving the utilization rate of the dust bag 310.

[0059] When the dust bag 310 needs to be unfolded, the negative pressure device 400 evacuates the first chamber 110, so that the airflow enters the second chamber 311 through the first air inlet 120 and the second air inlet 321 in sequence, and then the airflow enters the first chamber 110 through the air-permeable mesh 312, and then enters the negative pressure device 400 from the first air outlet 130; since the air pressure in the first chamber 110 is lower than the air pressure in the second chamber 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 evacuates air, the garbage can pass through the first air inlet and the second air inlet in sequence with the flow of airflow to reach the second chamber 311, so as to be collected by the dust bag 310, and the garbage entering the dust bag 310 further exerts a force on the dust bag 310 under the action of gravity, so that the dust bag 310 is further unfolded in the up and down directions, further improving the utilization rate of the dust bag 310.

[0060] The second embodiment of the present invention provides a cleaning device, including a dust collection station, which is the dust collection station described in the first embodiment of the present invention. The cleaning device also includes a dust storage container, which can be used in devices such as vacuum cleaners and sweeping robots to store the garbage they absorb.

[0061] The dust storage container is provided with a dust outlet, which is connected to the first air inlet 120. When it is necessary to collect the garbage in the dust storage container, air is drawn through the negative pressure device 400, so that the garbage can pass through the dust outlet, the first air inlet and the second air inlet in sequence with the flow of air to reach the second cavity 311, and then be collected by the dust bag 310.
