Description

Technical Field

[0001] This utility model relates to the technical field of floor cleaning machines, specifically to a dust collection device for hard surface cleaning equipment. Background Technology

[0002] A floor scrubber is a lightweight floor surface treatment device commonly used for floor grinding and polishing, especially for grinding concrete floors, grinding epoxy putty layers, and leveling floors. To provide a better dust-free working environment, some models also include a vacuum cleaner. Connecting the vacuum cleaner allows for the timely collection of dust generated during grinding. However, this can also trap larger, unground stones, causing blockages in the pipes and requiring disassembly for cleaning. In some existing models, the vacuum cleaner is an additional, separate unit, meaning it collects dust from the areas the cleaning disc has passed through. This method tends to be less effective at dust removal. Other designs integrate the vacuum cleaner into the overall structure, but this typically involves suction from above the grinding area. This requires navigating through a more convoluted pipe to collect the dust in the collection box, and larger stones are difficult to collect due to gravity. The collection box is also located inside the machine, making it inconvenient to remove for cleaning. Utility Model Content

[0003] To address the problems existing in the prior art, the present invention aims to provide a dust collection device for hard surface cleaning equipment. This invention adds an adsorption mechanism and a easily detachable collection box to the existing equipment body, facilitating the collection of debris and dust generated during floor polishing, and is also easy to disassemble and clean.

[0004] The present invention discloses a dust collection device for a hard surface cleaning equipment, comprising an adsorption mechanism located at the rear of the equipment body, a collection box connected below the adsorption mechanism, the collection box being detachably connected to the bottom of the equipment body, and one side of the collection box being connected to the space where the equipment body is polishing the ground via a pipe. When the adsorption mechanism is activated, it generates suction, thereby sequentially adsorbing the dust generated when the equipment body polishes the ground into the collection box through the collection box and the pipe.

[0005] In one embodiment, a mounting plate is provided on the bottom rear side of the device body, the adsorption mechanism is fixed on the mounting plate, the collection box is detachably connected to the bottom of the mounting plate, and the mounting plate has an opening in the middle for connecting the adsorption mechanism and the collection box.

[0006] In one embodiment, the mounting plate has hook-shaped grooves on both sides and an opening at the rear end. The two sides of the collection box are adapted to the grooves, so that the collection box and the mounting plate can be slidably connected.

[0007] In one embodiment, the top side of the collection box is provided with a cover plate, the middle of the cover plate is recessed and fixed with a positioning member, the positioning member is a hollow column, the upper end of the positioning member is connected to the adsorption mechanism, and a gap is left between the lower end of the positioning member and the bottom of the collection box.

[0008] In one embodiment, the bottom of the mounting plate is further provided with an elastic sealing ring corresponding to the position of the positioning member.

[0009] In one embodiment, the pipe is fixed to one side of the collection box opposite the device body, and the device body has an opening corresponding to the position of the pipe and is adapted to the pipe.

[0010] In one embodiment, the adsorption mechanism is a vortex fan.

[0011] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0012] This invention adds an adsorption mechanism and a easily detachable collection box to the original equipment body. The adsorption mechanism connects the collection box, pipes, and the grinding disc position of the equipment body when grinding the ground, directly adsorbing all the dust and debris generated at the grinding disc into the collection box. The adsorption channel is basically located on the plane of the bottom of the equipment body, so the adsorption mechanism does not need to provide greater suction to overcome the gravity of dust and debris, so as to collect the debris and dust generated during the grinding of the ground and temporarily fall into the collection box. The collection box is detachable and easy to disassemble, install, and clean, and can remove larger stones to avoid clogging of the internal channels. Attached Figure Description

[0018] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can be described as the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1-4 As shown, the dust collection device of the present invention for a hard surface cleaning equipment includes an adsorption mechanism 2 located at the rear of the equipment body 1. A collection box 3 is connected below the adsorption mechanism 2. The collection box 3 is detachably connected to the bottom of the equipment body 1. One side of the collection box 3 is connected to the space where the equipment body 1 is polishing the ground through a pipe 4. When the adsorption mechanism 2 is activated, it generates suction, thereby adsorbing the dust generated when the equipment body 1 polishes the ground into the collection box 3 through the collection box 3 and the pipe 4 in sequence. This invention adds an adsorption mechanism 2 and a easily detachable collection box 3 to the original equipment body 1. The adsorption mechanism 2 connects the collection box 3, the pipe 4, and the grinding disc position of the equipment body 1 when grinding the ground, directly adsorbing all the dust and debris generated at the grinding disc into the collection box 3. The adsorption channel is basically located on the bottom plane of the equipment body 1. The adsorption mechanism 2 does not need to provide greater suction to overcome the gravity of dust and debris, so as to collect the debris and dust generated during the grinding of the ground and temporarily fall into the collection box 3. The collection box 3 is detachable and easy to disassemble, install, and clean, and can remove larger stone particles to avoid clogging of the internal channel.

[0021] Furthermore, for ease of installation, a mounting plate 5 is provided on the rear bottom of the device body 1. The adsorption mechanism 2 is fixed on the mounting plate 5, and the collection box 3 is detachably connected to the lower part of the mounting plate 5. The mounting plate 5 has an opening in the middle for connecting the adsorption mechanism 2 and the collection box 3. By extending the mounting plate 5 to the rear and using the mounting plate 5 to fix the adsorption mechanism 2 and the detachably connected collection box 3, this device can be directly integrated into the original device body 1. The collection box 3 can be used as a corner by forming an inclined surface, and the suction force generated by the adsorption mechanism 2 above can more planarly adsorb dust and debris along the pipe 4. Moreover, the mounting plate 5 has hook-shaped grooves 6 on both sides and an opening at the rear. The two sides of the collection box 3 are adapted to the grooves 6, so that the collection box 3 and the mounting plate 5 can be slidably connected. The collection box 3 can be slidably connected through the grooves 6, and it is connected to the mounting plate 5 in a drawer-like manner. It can be removed from the rear to clean the dust adsorbed inside the collection box 3.

[0022] Specifically, the collection box 3, as a single movable component, has a cover plate 7 on its top side. The cover plate 7 has a recessed center and a positioning element 8 is fixed therein. The positioning element 8 is a hollow cylinder. Its upper end connects to the adsorption mechanism 2, and its lower end has a gap with the bottom of the collection box 3. The actual cross-section of the positioning element 8 is I-shaped with a hollow cylindrical center. Its upper end fits snugly onto the recessed cover plate 7, while its lower end leaves space at the bottom of the collection box 3 to form a handle. This allows the negative pressure generated by the adsorption mechanism 2 to pass through the positioning element 8 and the gap, creating suction inside the collection box 3. The gap also prevents larger debris or stones from directly entering the adsorption mechanism 2, providing a degree of protection. When the collection box 3 is completely removed, the dust and other debris inside can be cleaned directly by opening the cover plate 7 and the positioning element 8. The positioning element 8 can also be used to correspond to the through hole of the mounting plate 5. Furthermore, the bottom of the mounting plate 5 is provided with an elastic sealing ring 9 corresponding to the position of the positioning element 8. The elastic sealing ring 9 is used to fill the gap between the upper end of the positioning element 8 and the mounting plate 5. After the collection box 3 is reinstalled, the suction force generated by the adsorption mechanism 2 can be introduced from the middle of the positioning element 8 into the interior of the collection box 3 without causing air leakage at the connection point.

[0023] Furthermore, the pipe 4 is fixed on the side of the collection box 3 opposite to the device body 1, and the device body 1 has an opening corresponding to the position of the pipe 4, which is adapted to fit the pipe 4. Due to the sliding connection between the collection box 3 and the slide 6, the corresponding front-mounted pipe 4 can engage with the hole on the device body 1. When the collection box 3 is reinstalled under the mounting plate 5, the pipe 4 will be inserted into the hole and connected to the space for grinding the ground, thus positioning the collection box 3 and preventing it from falling off. In addition, the adsorption mechanism 2 can use a vortex fan, which provides annular suction to adsorb dust into the collection box 3 and also provides a certain blowing effect. When the collection box 3 is removed for cleaning, simple cleaning can be performed on areas such as the inside of the positioning part 8.
