Description

Technical Field

[0001] This utility model belongs to the field of dust absorption equipment, and in particular relates to a dust absorption device in a confined space. Background Technology

[0002] In industrial production, industrial vacuum cleaners are commonly used for dust removal in smaller workshops. These vacuum cleaners have a filter inside the drum, and a fan collects external dust into the drum. Currently, most of these vacuum cleaners have a long collection tube on the cleaning head, which connects to the suction tube on the drum. Cleaning is done manually by holding the collection tube, which is tiring and time-consuming. To address these issues, some industrial vacuum cleaners have been designed with the cleaning head fixed to a frame and wheels installed on it for movement. However, this design is limited, especially in situations with grooves or narrow spaces where the frame cannot pass through. Utility Model Content

[0003] In view of this, the present invention aims to overcome the shortcomings of the above-mentioned problems in the prior art and proposes a dust absorption device in a limited space.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A dust absorption device for a confined space includes a barrel body, which is mounted on the upper side of a movable frame. A suction pipe is connected to the barrel body, and a cleaning head is connected to the other end of the suction pipe. An arc-shaped retaining plate with a forward-facing opening is fixed to the front end of the movable frame. The cleaning head can be vertically engaged in the retaining plate. Limiting edges are provided on the upper and lower sides of the retaining plate on the cleaning head, and a limiting platform is provided on the cleaning head between the upper and lower limiting edges. When the cleaning head is engaged in the retaining plate, the two ends of the retaining plate correspond to and abut against the two ends of the limiting platform, and the upper and lower sides abut against the corresponding limiting edges.

[0006] Furthermore, the cleaning head includes an adsorption hood, a cleaning brush, and a connecting tube. The connecting tube is located on the upper side of the adsorption hood and is connected to the adsorption hood. The cleaning brush is installed inside the adsorption hood. The opening at the top of the connecting tube is connected to and fixed together with the vacuum tube.

[0007] Furthermore, the limiting edge and the limiting platform are both set on the connecting pipe and are integrally formed with the connecting pipe.

[0008] Furthermore, a connecting rod is fixed to the front end of the mobile frame, and a clamping plate is fixed to the front end of the connecting rod.

[0009] Furthermore, the arc center of the card plate is located inside the card slot of the card plate, and the arc radius of the card slot matches the corresponding radius dimension of the cleaning head.

[0010] Furthermore, the suction pipe is a corrugated pipe.

[0011] Furthermore, a handrail is fixed to the rear side of the mobile frame.

[0012] Furthermore, the mobile frame is equipped with casters at the four corners of its bottom.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] The dust absorption device for confined spaces described in this utility model is movable via a mobile frame, making it easy to move and use within the factory. When the mobile frame is moved, the cleaning head moves synchronously with the frame under the action of the clamping plate, eliminating the need for the operator to hold the cleaning head while cleaning. In narrow spaces where the mobile frame cannot easily pass through, the operator can remove the cleaning head from the clamping plate and clean it by hand. This device is a simple modification of an existing industrial vacuum cleaner, changing the cleaning head to be both handheld and clamped in the clamping plate, allowing for cleaning based on the movement of the mobile frame. This provides versatile operation and is suitable for cleaning in various confined spaces. Attached Figure Description

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] As shown in the figure, a dust absorption device for a confined space includes a barrel 1, which is mounted on the upper side of a movable frame 4. A suction pipe 2 is connected to the barrel 1, and a cleaning head 3 is connected to the other end of the suction pipe 2. An arc-shaped clamping plate 5 with an opening facing forward is fixed to the front end of the movable frame 4. The cleaning head 3 can be vertically clamped in the clamping plate 5. Limiting edges 32 are provided on the cleaning head 3 at the upper and lower sides of the clamping plate 5, and a limiting platform 33 is provided on the cleaning head 3 between the upper and lower limiting edges 32. When the cleaning head 3 is clamped in the clamping plate 5, the two ends of the clamping plate 5 correspond to and abut against the two ends of the limiting platform 33, and the upper and lower sides abut against the corresponding limiting edges 32. In this embodiment, the dust absorption device is moved by the mobile frame 4, making it easy to move and use in the factory. When the mobile frame 4 is moved, the cleaning head 3 moves synchronously with the mobile frame 4 under the action of the clamping plate 5, so that the operator does not need to hold the cleaning head 3 to perform cleaning operations. When the position is narrow and the mobile frame 4 is inconvenient to pass through, the operator can take the cleaning head 3 from the clamping plate 5 and hold it to perform cleaning.

[0025] The cleaning head 3 includes an adsorption cover 34, a cleaning brush 35, and a connecting tube 31. The connecting tube 31 is located on the upper side of the adsorption cover 34 and communicates with it. The cleaning brush 35 is installed inside the adsorption cover 34. The opening at the top of the connecting tube 31 is connected to and fixed together with the suction tube 2. In this embodiment, the adsorption cover 34 and the connecting tube 31 are integrally injection molded structures. The interface between the connecting tube 31 and the suction tube 2 is fixed together by heat fusion or by threaded connection, which is a conventional technical means in this field.

[0026] The limiting edge 32 and the limiting platform 33 are both set on the connecting pipe 31 and are integrally formed with the connecting pipe 31.

[0027] A connecting rod 6 is fixed to the front end of the movable frame 4, and a clamping plate 5 is fixed to the front end of the connecting rod 6, so that the cleaning head 3 can be slightly away from the movable frame 4, and the cleaning head 3 is not constrained by the movable frame 4 when it needs to be clamped in the clamping plate 5.

[0028] The center of the arc of the card plate 5 is located inside the slot of the card plate 5, that is, the arc length of the card plate 5 is greater than the arc length of a semicircle with the same arc radius, and the arc radius of the slot matches the corresponding radius on the cleaning head 3. In this embodiment, the card plate 5 is made of hard plastic material with a certain deformation and recovery capability.

[0029] The vacuum hose 2 is a corrugated hose, which makes it easy for the vacuum hose 2 to extend and retract.

[0030] A handrail 7 is fixed to the rear of the mobile frame 4 to facilitate the operator's movement of the device.

[0031] The mobile frame 4 is equipped with casters 8 at the four corners of its bottom for easy movement.

[0032] In this embodiment, when the cleaning head 3 is attached to the card plate 5, the bottoms of the cleaning head 3 and the caster wheel 8 are close together, ensuring that the cleaning head 3 can perform cleaning smoothly during movement.

[0033] In this embodiment, the distance between the upper and lower limit edges 32 matches the height of the card plate 5, ensuring that the cleaning head 3 will not move up and down when it is inserted into the card plate 5.

[0034] In this embodiment, the internal structure of the barrel 1 is common knowledge that can be grasped by those skilled in the art. It is a conventional structure in industrial vacuum cleaners, and the innovation of this application does not lie in this. Therefore, its internal structure will not be described in detail here.

[0035] The working process of this embodiment is as follows:

[0036] When the cleaning head 3 is engaged in the slot of the clamping plate 5, the longitudinal movement of the cleaning head 3 is restricted by the upper and lower limit edges 32, and the circumferential movement of the cleaning head 3 in the horizontal plane is restricted by the limit platform 33. The combination of these two measures ensures the stability of the cleaning head 3 within the clamping plate 5. When encountering narrow areas, such as where the moving frame 4 cannot pass, or where there are narrow depressions on the ground, the cleaning head 3 can be removed and held by hand for cleaning.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
