[0030] Figures 1-6 This is one or more embodiments of the present utility model.

[0031] The control lever structure 100 is used to connect with the cleaning equipment, allowing the user to hold and push the cleaning equipment to work on the floor to be cleaned.

[0032] The control lever structure 100 includes a grip portion 110, a connecting rod portion 120, and a clearance portion 130. The grip portion 110 provides a grip for user operation. One end of the connecting rod portion 120 is connected to the grip portion 110, and the other end is connected to the clearance portion 130. The connecting rod portion 120 is a hollow or open structure, and a battery 200 is installed inside. The battery 200 is used to power electronic components. Placing the battery 200 inside the connecting rod portion 120 has at least two advantages: First, it saves space on the cleaning equipment base, facilitating a lightweight design. Second, placing the battery 200 inside the connecting rod portion 120 keeps it away from the cleaning equipment base and the surface to be cleaned. This is especially important for cleaning equipment that involves water, as the battery needs to be kept away from the ground to prevent dirt, wastewater, and moisture from entering the battery. Increasing the distance between the battery and the ground, compared to placing the battery on the cleaning equipment base, makes the battery safer and improves its reliability.

[0033] During implementation, the design of the operating lever structure ensures that the thickness d of the clearance part 130 is less than the radial width D1 of the connecting rod part 120, thereby realizing the clearance function of the operating lever structure in this solution. When the operating lever structure 100 is lying flat, the clearance part 130 matches the shape of the cleaning equipment. The clearance part 130 can avoid the external contour of the cleaning equipment. That is, when the operating lever structure is lying flat, the design of the clearance part 130 can compress the local space of the operating lever structure 100, so that the operating lever structure 100 will not collide with the external contour of the cleaning equipment, nor will it be pushed too high by the contour of the cleaning equipment. This reduces the space occupied by the operating lever structure 100 when it is lying flat, making it easier to reduce the working volume of the equipment.

[0034] When the control lever structure 100 is laid flat, the machine thickness can be reduced as much as possible, and the design of the clearance part 130 can reduce the weight of the cleaning equipment body, which is conducive to lightweight design and user operation.

[0035] In one embodiment, the clearance portion 130 includes a first clearance surface 1310 and a second clearance surface 1320, which are connected. The first clearance surface 1310 and the second clearance surface 1320 can also be transitioned by rounded corners. When the operating lever structure is flat, the second clearance surface 1320 fits against the outer contour of the cleaning device. This fit can be close to, or a zero-fit contact, or have a small gap of less than 5mm. The first clearance surface 1310 can avoid the outer contour of the cleaning device. In other embodiments, when the operating lever structure is flat, the second clearance surface 1320 can be parallel to the outer surface contour of the cleaning device. Alternatively, in other embodiments, a curved surface with an arc can be used instead of the first clearance surface 1310.

[0036] In one embodiment, the lever structure 100 is made of carbon fiber composite material, plastic or metal. In specific implementation, one or both of the grip part 110 and the connecting rod part 120 may be made of carbon fiber composite material, plastic or metal.

[0037] In one embodiment, the connecting rod 120 can be designed as a straight rod. Along the longitudinal extension direction of the connecting rod 120, or along its length, there exists a continuous region R. The length of this region R accounts for at least 70% of the total length of the connecting rod 120. Within this region R, the radial width D1 of the connecting rod 120 at any point does not vary by more than ±5% of its average width, maintaining the consistency and harmony of the connecting rod 120's shape. Furthermore, the radial width D1 of the connecting rod 120 is controlled to not exceed 80mm. Compared to the existing design with a body width of approximately 110mm, its width is reduced by at least a quarter, resulting in a smaller volume occupied by the operating lever structure and a reduced weight. This not only aids user operation but also makes the operating lever structure more material-efficient and easier to store. Moreover, the design maintains an almost uniform radial width across most areas of the connecting rod 120, which also helps improve the overall integrity of the connecting rod. In some embodiments, the connecting rod 120 can be detached or spliced ​​with the gripping part 110 and the clearance part 130, and can be selectively assembled. Of course, in other embodiments, the connecting rod 120, the gripping part 110, and the clearance part 130 can also be connected by integral molding, or even two of them can be integrally molded and then spliced / connected with the other one. The way to achieve the connection is not fixed.

[0038] In one embodiment, to further reduce the volume of the connecting rod 120, the design avoids adding weight to the connecting rod 120 by attaching external components to its surface. In this implementation, after the connecting rod 120 is spliced ​​and connected with the grip 110 and the clearance part 130, all the outer contours of the connecting rod 120's outer surface are exposed to the outside air. Under normal operating conditions, the surface of the connecting rod has no coverings or fixed parts, allowing only the following non-functional contacts: a) user's hand grip; b) ambient air; c) temporary deposits (such as water stains or dust) that do not affect the rod's contour; d) magnetic attraction. That is, no other external components are attached to the connecting rod 120. Other components include, but are not limited to, water tanks, motors, cable holders, tool racks, and other components requiring bolt / clip fastening. For example, the clean water tank or waste water tank is no longer externally mounted on the connecting rod 120, meaning there is no longer a problem of the clean water tank or waste water tank sharing the same edge or surface with the outer contour of the connecting rod 120. The pipes for the clean water tank and waste water tank are also no longer installed on the connecting rod 120. This reduces the weight of the connecting rod 120, saving the user's operating effort. This design aims to achieve a better humanized design and a better user experience.

[0039] In one embodiment, an ambient light 1210 is also provided on the connecting rod 120. The design of the ambient light 1210 enhances the lighting effect of the connecting rod 120, making the connecting rod 120 exhibit a more advanced process structure effect.

[0040] To facilitate the operation of the joystick structure 100, an anti-slip cone 1110 and a display screen 1120 are provided on the grip 110. The anti-slip cone 1110 is located at the bottom of the grip 110, and the display screen 1120 is located at the top of the grip 110. The display screen 1120 displays the working status of the cleaning equipment, and the anti-slip cone 1110 is designed to facilitate the user's grip on the grip 110, providing an anti-slip effect, which plays an irreplaceable role in the user-friendly design. Batteries can power both the display screen and the ambient light separately.

[0041] This solution also provides a pole-type floor scrubber 10, including an operating lever structure 100 and a base 200. The base 200 is connected to the operating lever structure 100 via a universal joint, allowing the operating lever structure 100 to rotate around the base 200.

[0042] In one embodiment, considering the problem that the base of the current floor scrubber may inadvertently tilt during operation, the operating lever structure 100 of this solution is set or connected to the central area of ​​the base 200 to balance the weight distribution of the floor scrubber, so that the user can operate the floor scrubber more stably and fit the floor to be cleaned, making it less likely for the floor scrubber to tilt and affect the cleaning performance.

[0043] In order to make the operating rod structure 100 as thin and light as possible, the thickness of the connecting rod part should be controlled within 80 mm. However, while ensuring the thickness design of the operating rod structure 100, it is also necessary to take into account maintaining the strength of the operating rod structure 100 to avoid breakage of the operating rod structure, and at the same time be able to avoid the outline of the base 200 of the floor washer. Then, the avoidance part 130 needs to be refined so that the avoidance part 130 can achieve thinness and lightness, maintain strength, and when the operating rod structure is in the lying position, it can smoothly avoid the outline of the floor washer. The parameter of the depth D2 of the avoidance part can be designed as follows: the depth D2 of the avoidance part 130 and the maximum height H_max of the base 200 in the lying direction satisfy D2 < H_max. In one implementation, control the depth D2 of the avoidance part 130 to satisfy 0.1H_max ≤ D2 ≤ 0.8H_max. In order to make the design of the avoidance part 130 more perfectly adapted to the floor washer, the avoidance part 130 needs to be designed with a first avoidance surface 1310, and the angle of the first avoidance surface 1310 needs to be controlled so that when the operating rod structure lies flat, the included angle α between the first avoidance surface 1310 and the ground to be cleaned satisfies α ≥ 90 degrees, making α an obtuse angle or a right angle, and the best way is an obtuse angle, so that the outline of the base 200 can smoothly slide into the avoidance part 130 along the first avoidance surface 1310 without causing the avoidance part to collide with the outline of the cleaning device; as Figure 6 The schematic diagram of the included angle α when the operating rod structure of the rod-type floor washer in

[0044] In one implementation, in order to avoid the surface of the avoidance part 130 being scratched due to friction with the surface of the base 200 of the floor washer, a low-friction coating can be applied to the surface of the avoidance part 130 or the base 200, or the low-friction coating can also be applied separately to the surface of the first avoidance surface 1310, so as to reduce the surface friction that may come into contact, and the friction coefficient ≤ 0.2.

[0045] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.

[0046] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
