Description

Technical Field

[0001] This utility model relates to the field of household cleaning appliances, and in particular to a cleaning device. Background Technology

[0002] Current cleaning equipment, especially floor scrubbers, typically integrates the waste collection tank into the control lever body, with a universal joint connecting the body and base. This necessitates that the universal joint, the connection between the base and the control lever body, balance the requirements for waste and airflow while maintaining rigidity and hardness. This often necessitates making the universal joint quite large, with a diameter of 30mm or even more. This results in a bulky universal joint that also needs a flexible hose for waste and airflow, which is prone to cracking and leakage due to repeated rotation. Furthermore, the large universal joint structure makes the control lever body less smooth to operate during use. Moreover, current universal joint designs cannot achieve miniaturization and lightweighting of the connection between the base and control lever body, leading to material waste in the floor scrubber design. Therefore, miniaturizing the universal joint and reducing its size is a problem that the cleaning equipment industry needs to solve. Utility Model Content

[0003] Therefore, it is necessary to provide a cleaning device to solve the problems existing in the prior art.

[0004] A cleaning device includes a base, an operating lever body, and a waste container. The waste container is disposed on the base, and the base has a waste inlet channel communicating with the waste container. The base and the operating lever body are rotatably connected by a universal joint. The cleaning device also includes a rigid connecting piece, and the universal joint is connected to the rigid connecting piece to form a rotating shaft assembly. The rigid connecting piece serves as a transition connector between the base and the operating lever body. The first end of the rigid connecting piece is connected to the operating lever body, fixing the rigid connecting piece to the operating lever body. The rigid connecting piece is adapted to and fixed to the base by the universal joint. The operating lever body can rotate around the universal joint between a working position and a locked position. The average thickness of the rigid connecting piece does not exceed 10 mm. The base also has a locking structure. When the operating lever body is in the locked position, the locking structure adapts to the rotating shaft assembly to lock the operating lever body.

[0005] Furthermore, a through hole is provided at the second end of the rigid connecting piece, and the universal joint is adapted and connected through the through hole.

[0006] Furthermore, the rigid-tough connecting piece is a metal connecting piece.

[0007] Furthermore, the metal connecting piece is an L-shaped metal connecting piece; the first end is fixed to the operating lever body by insertion, welding or bolt connection; the average thickness of the L-shaped metal connecting piece does not exceed 5mm.

[0008] Furthermore, the locking structure includes a magnetic component disposed on the base; when the operating lever body is rotated to the locked position, the magnetic component attracts the metal parts through magnetic attraction, thereby locking the operating lever body.

[0009] Furthermore, the metal component is the rigid connecting piece, and the magnetic component is disposed on the base at a position corresponding to the rigid connecting piece; when the operating lever body rotates to the locked position, the magnetic component attracts the rigid connecting piece through magnetic attraction, thereby locking the operating lever body.

[0010] Furthermore, the locking structure includes a locking point and a spring. The locking point is located on the base, and the spring provides an elastic restoring force. When the operating lever body rotates to the locked position, the universal joint presses against the locking point and compresses the spring until the locking point engages and is fixed with the universal joint.

[0011] Furthermore, the cleaning equipment is a floor scrubber.

[0012] The cleaning equipment in this solution places the waste collection box and waste inlet channel on the base, avoiding placing the waste collection box on the operating lever body. This eliminates the need for a flexible hose for passing waste and airflow, thus avoiding the need to create waste and airflow channels on the universal joint between the base and the operating lever body. This design incorporates the wastewater and airflow channels within the base, eliminating the need for a separate wastewater hose. This minimizes the thickness of the universal joint between the base and the operating lever body, allowing for a smaller and thinner design that occupies less space, thus promoting miniaturization and material savings. To ensure the rigidity and stiffness of the connectors and prevent cracking due to insufficient rigidity during operation, the connectors are designed as rigid-tough connecting plates, preferably metal. This ensures rigidity while maximizing the slimness and thinness of the connectors, resulting in a miniaturized and lightweight connection structure between the cleaning equipment base and the operating lever body. With the rigid-tough connecting plate thickness controlled to less than 10mm, compared to the existing universal joint diameter of at least 30mm, this design reduces the lateral space occupied by the universal joint and connecting plate by at least 66%, saving design space and materials, and further promoting the miniaturization and lightweighting of cleaning equipment. Eliminating the hoses for passing garbage and airflow also avoids the problem of hoses cracking and leaking garbage. Attached Figure Description

[0028] Figures 1-7 This is one or more embodiments of the present utility model.

[0029] In one embodiment, the cleaning device 100 includes a base 110, a lever body 120, and a waste container 130. The waste container 130 is disposed on the base 110, and the base 110 has a waste inlet channel 111 communicating with the waste container 130. The waste container 130 may be detachably mounted on the base 110 or non-detachably mounted on the base 110. The base 110 and the lever body 120 are rotatably connected via a universal joint 140. The cleaning device 100 may be a floor scrubber, a stick vacuum cleaner, etc.

[0030] The universal joint 140, connected to the rigid connecting piece 150, allows the universal joint and the rigid connecting piece to form a rotating shaft assembly. The rigid connecting piece 150 serves as a transitional connector between the base 110 and the operating lever body 120. The rigid connecting piece 150 can be made of metal or other materials with similar, slightly weaker, or stronger toughness and rigidity. Its main function is to connect the operating lever body 120 and the base 110, ensuring that the connector is not easily deformed, broken, or damaged during rotation, twisting, or turning of the operating lever body 120. The connection between the rigid connecting piece 150 and the universal joint 140 can be such that the universal joint 140 is located in the middle, at the end, or at other positions on the rigid connecting piece 150. The rigid connecting piece 150 and the universal joint 140 are fitted together and fixed to the base 110.

[0031] In one embodiment, the rigid connecting piece 150 has a first end 151 and a second end 152. The first end 151 is connected to the operating lever body 120, fixing the rigid connecting piece 150 to the operating lever body 120. The second end 152 is connected to the base 110 via a universal joint 140. The operating lever body 120 can rotate around the universal joint 140 between a working position and a locked position. The rigid connecting piece 150 has a thickness of no more than 10 mm to reduce the thickness of the connecting piece and minimize its design space. The base 110 also has a locking structure 160. When the operating lever body 120 is in the locked position, the locking structure 160 engages with the rotating shaft assembly to lock the operating lever body 120.

[0032] This design places both the waste inlet channel and the waste collection box on the base, avoiding the waste collection box being located on the operating lever body. This eliminates the need for a hose passage for waste between the base and the operating lever body, and also eliminates the hose passage for waste within the universal joint. In other words, the universal joint only includes a rotating structure and no longer requires a channel for waste or airflow. This allows for a smaller universal joint structure, saving design materials and space, and simplifying the design of connectors. A rigid and flexible connecting piece 150 is used to seamlessly connect the base 110 and the operating lever body 120, solving the problem of hose cracking and waste leakage in the universal joint caused by frequent pushing, pulling, and rotating of the operating lever body 120 in existing cleaning equipment. The use of the rigid and flexible connecting piece 150 in this design allows for a smaller and thinner connection structure, avoiding material waste and space occupation, promoting the miniaturization and lightweight development of cleaning equipment. Eliminating the hose for waste and airflow also avoids the problem of hose cracking and waste leakage.

[0033] To facilitate locking of the joystick body 120, in one embodiment, the locking structure 160 includes a magnetic component 1601. The magnetic component 1601 is disposed on the base 110. The joystick body 120 can be fixed by the magnetic attraction between the magnetic component 1601 and the metal part. In the implementation process, when the joystick body 120 is rotated to the locked / locked position, the magnetic component 1601 attracts the metal part to lock the joystick body 120. The metal part can be the rigid connecting piece 150 or other metal parts, as long as it can be attracted by the magnetic component 1601 when the joystick body 120 is rotated to the locked / locked position. In the implementation process, the metal part can be placed on the joystick body 120 so that the magnetic component 1601 can attract it so that when the joystick body 120 is in the locked position, the magnetic effect of the magnetic component 1601 can lock the joystick body 120. In one embodiment, the metal component is directly a rigid connecting piece 150, and the magnetic component 1601 is positioned on the base in a manner that corresponds to and matches the rigid connecting piece 150. Specifically, when the operating lever body 120 is rotated to the locked / stopped position, the magnetic component 1601 is positioned to attract the rigid connecting piece 150. When the operating lever body 120 is rotated to the locked position, the magnetic component 1601 attracts the rigid connecting piece 150 through magnetic attraction, thus locking the operating lever body 120. The magnetic component 1601 can be a magnet or other magnetically conductive material.

[0034] In another embodiment, other locking methods can be used. The locking structure 160 includes a locking point 161 and a spring 162. The locking point 161 is located on the base 110, and the spring 162 provides an elastic restoring force. When the operating lever body 120 rotates to the locked position, the part of the universal joint 140 that cooperates with the locking point 161 presses against the locking point 161 and compresses the spring 162. As the operating lever body 120 rotates, the locking point 161 engages and is fixed with the universal joint 140, thereby locking the operating lever body 120.

[0035] The cleaning equipment provided in this solution places the waste collection box and waste inlet channel in the base, avoiding the placement of the waste collection box on the operating lever body. This eliminates the need for waste and airflow channels in the universal joint connecting the base and the operating lever body. By placing the waste and airflow channels in the base, this solution minimizes the thickness of the universal joint connecting the base and the operating lever body, making it thinner. Simultaneously, it considers the requirements for rigidity and stiffness, preventing cracking due to insufficient rigidity in the connection between the base and the operating lever body during operation. A rigid and flexible connecting plate is used as the connection between the base and the operating lever body, ensuring the rigidity of the connection while maximizing its ultra-thin design. This results in a miniaturized and lightweight design of the rigid and flexible connecting plate between the cleaning equipment base and the operating lever body. By controlling the thickness of the rigid-tough connecting piece to within 10mm, compared to the universal joint diameter of 30mm and above in the existing technology, the rigid-tough connecting piece of this solution occupies at least 66% of the lateral volume. This not only saves design space and materials, but also promotes the miniaturization and lightweighting of cleaning equipment.

[0036] In one embodiment, to facilitate the connection between the universal joint 140 and the rigid connecting piece 150, a through hole 1520 can be provided at the second end 152, and the universal joint 140 can be connected to the base 110 through this through hole 1520. The universal joint 140 and the through hole 1520 can be in clearance fit, or the through hole 1520 can be used to allow the operating lever body 120 to rotate around the universal joint 140. To better accommodate the L-shaped connection between the base 110 and the operating lever body 120, the rigid connecting piece 150 can be designed as an L-shaped metal connecting piece. This design maximizes the ease of rotation between the rigid connecting piece 150 and the operating lever body 120, minimizing the space occupied by the rotating structure of the operating lever body 120 in the base 110, thus facilitating rotation.

[0037] In one embodiment, the first end 151 is fixed to the operating lever body 120 by plugging, welding or bolting. At the same time, in order to further reduce the volume occupied by the connector, the thickness of the L-shaped metal connecting piece can be controlled to no more than 5mm, and ideally it can even be controlled to within 3mm.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
