Description

Technical Field

[0001] This application relates to the field of cleaning equipment, and in particular to an airbag. Background Technology

[0002] With the development of society and economy and the improvement of family living standards, cleaning equipment is being used more and more widely in daily life. In related technologies, in order to reduce the risk of collision between cleaning equipment and obstacles in front of it, a buffer structure is set at the front of the cleaning equipment to mitigate the interaction force generated when the cleaning equipment collides with the obstacle. For example, the infinitely variable speed vacuum cleaner disclosed in CN217137882U has an airbag at the front of the floor brush to mitigate the impact force generated during the collision.

[0003] However, due to the airbag design, the suction inlet of the floor brush is difficult to get close to obstacles, making it difficult to clean dust near obstacles, especially at the corner in front of the floor brush and along the edge of obstacles on the side of the floor brush. Utility Model Content

[0004] Therefore, it is necessary to provide an airbag that can clean dust near obstacles.

[0005] On one hand, this application provides an airbag for use in cleaning equipment; the airbag includes:

[0006] The body has an air cavity; the body can be compressed along a first direction; one end of the body along the first direction is an air inlet; the air inlet of the body is provided with an air inlet; the air inlet connects the air cavity and the external environment; the body has a first end and a second end arranged opposite to each other along a second direction; the second end of the body is provided with an air outlet, which connects the air cavity and the external environment when opened;

[0007] When the body is compressed along the first direction, the air outlet opens so that the gas in the air chamber flows out through the air outlet.

[0008] Optionally, when the body extends along the first direction and the air inlet is open, the air outlet is reduced or closed.

[0009] Optionally, the air outlet is an air outlet that extends along a third direction; the third direction is perpendicular to both the first direction and the second direction.

[0010] Optionally, the second end of the main body is provided with a plurality of air outlets; the plurality of air outlets include a plurality of first air outlets spaced apart along the third direction and a plurality of second air outlets spaced apart along the third direction; along the first direction, the first air outlets and the second air outlets are spaced apart; along the third direction, the first air outlets and the second air outlets are alternately arranged.

[0011] Optionally, along the third direction, the interval between adjacent first air outlets and second air outlets is 0.

[0012] Optionally, along the first direction, the air outlet is located near the air inlet of the body.

[0013] Optionally, the body includes a corrugated peripheral wall; the direction of the annular corrugations of the corrugated peripheral wall is perpendicular to the first direction.

[0014] Optionally, the air inlet end of the body has a protrusion, and the air inlet is disposed on the protrusion.

[0015] Optionally, along the second direction, with the bottom end of the body as a reference, the height of the bottom end of the air inlet is higher than the height of the maximum protrusion position of the protrusion.

[0016] Optionally, the airbag further includes:

[0017] A reset mechanism is used to provide a reset force for the extension of the body.

[0018] In several embodiments provided in this application, when the airbag is applied to a cleaning device, the second end of the main body faces the surface to be cleaned. When the main body encounters an obstacle and is compressed, the gas in the air chamber flows out from the air outlet to blow up dust near the obstacle, making it easier for the cleaning device to suck up the dust, thus cleaning the dust near the obstacle.

[0019] In some embodiments provided in this application, the air outlet is a slit extending along a third direction; this third direction is perpendicular to both the first and second directions. On one hand, since the air outlet is a slit, it can decrease or close as the body extends along the first direction, resulting in a simple structure. On the other hand, the air outlet extending along the third direction ensures a more uniform distribution of airflow along this direction, more evenly dispersing dust near obstacles and improving the uniformity of the cleaning effect. Furthermore, the extension of the air outlet along the third direction ensures that the speed at which the air outlet decreases or closes at different positions along the third direction is approximately the same as the speed at which it does so when the body extends along the first direction, reducing deformation of the sidewalls of the air outlet caused by inconsistent opening sizes and airflow.

[0020] In some embodiments provided in this application, there are multiple air outlets, which allow the gas in the air chamber to flow out more quickly when the body is compressed. The first and second air outlets are spaced apart along a first direction, thus allowing for more outlets without connecting them, and better distributing the gas in the air chamber. The first and second air outlets are alternately arranged along a third direction, making the airflow blown out of the air chamber through the outlets more evenly distributed along the third direction, so that dust near obstacles can be blown up more evenly.

[0028] To make the technical solution and beneficial effects of this application more apparent and understandable, a detailed description is provided below by listing specific embodiments. The accompanying drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly show the details of the local features; unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application pertains.

[0029] See Figures 1 to 5An embodiment of this application provides an airbag 100, which is applied to a cleaning device. The airbag 100 includes a body 110. The body 110 has an air cavity 111. The body 110 is compressible along a first direction aa. One end of the body 110 along the first direction aa is an air inlet 112. The air inlet 112 of the body 110 is provided with an air inlet 113. The air inlet 113 connects the air cavity 111 and the external environment. The body 110 has a first end 114 and a second end 115 disposed opposite to each other along a second direction bb. The second end 115 of the body 110 is provided with an air outlet 116. When the air outlet 116 is open, it connects the air cavity 111 and the external environment. When the body 110 is compressed along the first direction aa, the air outlet 116 opens so that the gas in the air cavity 111 flows out through the air outlet 116.

[0030] When the airbag 100 is applied to a cleaning device, the second end 115 of the body 110 faces the surface to be cleaned. When the body 110 is compressed when it encounters an obstacle, the gas in the air chamber 111 flows out from the air outlet 116 to blow up the dust near the obstacle, making it easier for the cleaning device to suck up the dust, thus cleaning the dust near the obstacle.

[0031] Optionally, when the airbag 100 is applied to a cleaning device, the first direction aa is the front-to-back direction of the cleaning device, and the airbag 100 is located at the front end of the cleaning device. When the cleaning device encounters an obstacle in front of it, it can mitigate the impact force generated during the impact.

[0032] In this embodiment, the first direction aa is perpendicular to the second direction bb. When the airbag 100 is applied to the cleaning device, the first direction aa is the front-to-back direction of the cleaning device's movement; the second direction bb is the direction perpendicular to the surface to be cleaned.

[0033] Optionally, when the body 110 extends along the first direction aa and the air inlet 113 is open, the air outlet 116 decreases or closes. Thus, when the airbag 100 is applied to a cleaning device, the process of the body 110 extending along the first direction aa is the process of the cleaning device moving away from obstacles. During this process, the air outlet 116 decreases or closes, reducing the risk of dust being drawn into the air chamber 111 from the air outlet 116.

[0034] In this embodiment, the air outlet 116 is a slit extending along a third direction cc; the third direction cc is perpendicular to both the first direction aa and the second direction bb. On the one hand, since the air outlet 116 is a slit, when the body 110 extends along the first direction aa, the air outlet 116 can be reduced or closed as the body 110 extends, resulting in a simple structure. On the other hand, since the air outlet 116 extends along the third direction cc, the airflow blown out through the air outlet 116 is more evenly distributed along the third direction cc, thereby more evenly blowing up dust near obstacles and improving the uniformity of the cleaning effect.

[0035] Furthermore, the air outlet 116 extends along the third direction cc, so that when the body 110 extends along the first direction aa, the air outlet 116 decreases or closes at approximately the same speed at different positions along the third direction cc, thereby reducing the deformation of the sidewall of the air outlet 116 caused by inconsistent opening size and inconsistent air intake.

[0036] Optionally, the length of the air outlet 116 extending in the third direction (cc) falls within the range of 2mm to 10mm. If the length of the air outlet 116 extending in the third direction (cc) is greater than or equal to 2mm, it can have a larger air outlet area after the air outlet 116 is opened, thus better blowing away dust near obstacles. If the length of the air outlet 116 extending in the third direction (cc) is less than or equal to 10mm, the air outlet 116 can be easily reduced or closed when the body 110 is extended, thereby reducing the risk of dust entering the air chamber 111 through the air outlet 116.

[0037] Specifically, the length of the air outlet 116 extending along the third direction cc can be any value within the range of 2mm to 10mm, such as 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, and 10mm.

[0038] Of course, it is understood that in some other embodiments, the direction of the air outlet is not limited to the third direction, but can also be along any other direction that is not co-located with the third direction.

[0039] In this embodiment, the second end 115 of the body 110 is provided with multiple air outlets 116; the multiple air outlets 116 include multiple first air outlets 1161 spaced apart along a third direction cc, and multiple second air outlets 1162 spaced apart along a third direction cc; along a first direction aa, the first air outlets 1161 and second air outlets 1162 are spaced apart; along a third direction cc, the first air outlets 1161 and second air outlets 1162 are alternately arranged. The multiple number of air outlets 116 allows the gas in the air chamber 111 to flow out more quickly through the air outlets 116 when the body 110 is compressed. The first air outlets 1161 and second air outlets 1162 are spaced apart along the first direction aa, thereby allowing for more air outlets 116 to be provided without connecting them, thus better diverting the gas in the air chamber 111. The first air outlet 1161 and the second air outlet 1162 are alternately arranged along the third direction cc, so that the airflow blown out of the air chamber 111 through the air outlet 116 is more evenly distributed along the third direction cc, so that the dust near the obstacle can be blown up more evenly.

[0040] In this embodiment, along the third direction, the adjacent first air outlet 1161 and second air outlet 1162 partially overlap, so that the airflow blown out through the air outlet 116 is uninterrupted along the third direction cc, so as to clean the dust in different locations near the obstacle.

[0041] In other embodiments, adjacent first and second air outlets may not overlap along a third direction. For example, in some embodiments, the interval between adjacent first and second air outlets along a third direction is [specified value]. Thus, when the body is compressed, the airflow blown out through the outlets continues along a third direction, allowing airflow near obstacles to be better blown up.

[0042] It is understandable that although the interval between adjacent first and second air outlets is zero along the third direction, the first and second air outlets are still spaced apart because they are spaced apart along the first direction. This has little impact on the strength of the sidewalls of the first and second air outlets, and facilitates the opening, shrinking or closing of the first and second air outlets.

[0043] Of course, it is understandable that in some other embodiments, the interval between adjacent first and second air outlets along a third direction may be greater than zero.

[0044] See Figures 1 to 5Specifically, in this embodiment, multiple first air outlets 1161 are evenly spaced along a third direction cc, and multiple second air outlets 1162 are evenly spaced along a third direction cc. The lengths of the multiple first air outlets 1161 extending along the third direction cc are all equal, and the lengths of the multiple second air outlets 1162 extending along the third direction cc are all equal, and the length of the first air outlet 1161 extending along the third direction cc is equal to the length of the second air outlet 1162 extending along the third direction cc. When the body 110 is compressed along the first direction aa, the airflow blown out of the air chamber 111 through the air outlets 116 is more evenly distributed along the third direction cc, so that dust near obstacles can be blown up more evenly.

[0045] Along the first direction aa, the air outlet 116 is close to the air inlet 112 of the body 110, so that the airflow blown out through the air outlet 116 can get closer to the obstacle, so as to better blow up the dust near the obstacle.

[0046] In this embodiment, the body 110 includes a corrugated peripheral wall 117; the annular corrugations of the corrugated peripheral wall 117 are perpendicular to the first direction aa, which facilitates the compression of the body 110 along the first direction aa, thereby allowing the gas in the air cavity 111 to flow out more smoothly from the air outlet 116.

[0047] In this embodiment, the body 110 is an elastic body 110. The air outlet 116 is located at or near the protrusion mechanism of the corrugated peripheral wall 117. Thus, when the body 110 is compressed, the air outlet 116 can open more quickly; when the body 110 is extended, the air outlet 116 can close more quickly.

[0048] Optionally, the body 110 has sidewalls arranged opposite each other along a third direction (cc), the thickness of which is greater than the thickness of the sidewalls at the first end 114 and the second end 115 of the body 110. The thicker sidewalls along the third direction (cc) of the body 110 provide better support, reducing the risk of sagging at the air inlet end 112 of the body 110. The thinner sidewall at the second end 115 of the body 110 facilitates deformation, thereby facilitating the opening and closing of the air outlet 116; and also reduces the weight of the body 110, further reducing the risk of sagging at the separate air inlet end 112.

[0049] Optionally, the sidewall thickness of the air inlet 112 of the main body 110 is less than or equal to the sidewall thickness of the main body 110 which is set opposite to each other along the third direction cc, so that the weight of the main body 110 is smaller and the risk of the split air inlet 112 sagging is reduced.

[0050] Optionally, the body 110 is made of soft polyvinyl chloride, thermoplastic polyurethane elastomer, or silicone. Optionally, the thickness of the sidewalls of the body 110 opposite to each other along the first direction aa and the second direction bb falls within the range of 0.6 mm to 3 mm, and the thickness of the sidewalls of the body 110 opposite to each other along the third direction cc falls within the range of 0.6 mm to 4 mm.

[0051] It is understood that in some other embodiments, the body is not limited to an elastic body, but can also be formed of a non-elastic material that is compressible along the first direction.

[0052] It is understood that in some other embodiments, the shape of the body is not limited to this, and it can be compressed along the first direction, which is not limited here.

[0053] In this embodiment, the air inlet end 112 of the main body 110 has a protrusion 118, and the air inlet 113 is provided on the protrusion 118. Thus, when the airbag 100 approaches an obstacle, the air inlet 113 can be blocked earlier, thereby allowing more gas in the air chamber 111 to flow out through the air outlet 116.

[0054] Optionally, along the second direction bb, with the bottom end of the body 110 as a reference, the height of the bottom end of the air inlet 113 is higher than the height of the maximum protrusion position of the protrusion 118. By blocking the protrusion 118, the risk of blown dust entering the air chamber 111 through the air inlet 113 is reduced.

[0055] In this embodiment, the air inlet 113 is circular, with a simple structure and easy processing. It is understood that in other embodiments, the air inlet is not limited to a circle, but may also be square, rhomboid, or other regular or irregular shapes.

[0056] In some embodiments, the airbag further includes a reset mechanism. The reset mechanism provides a reset force for the extension of the body, allowing the body to extend more quickly.

[0057] Optionally, the reset mechanism is an elastic element disposed within the air cavity. When the main body is compressed along the first direction, it simultaneously overcomes the elastic force of the reset mechanism, that is, the elastic deformation of the reset mechanism increases; when the main body extends along the first direction, the reset mechanism extends under the action of its own elastic force, thereby assisting the main body in extending.

[0058] Alternatively, the reset mechanism may be, but is not limited to, a spring.

[0059] Optionally, the reset mechanism is an air supply mechanism; the air supply port of the reset mechanism is connected to the air chamber. When the main body extends, the air chamber is inflated through the reset mechanism to assist in the extension of the main body.
