[0027] In order to make the person skilled in the art better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the present application.
[0028] It should be noted that the embodiments and the features and technical solutions in the embodiments in the present application can be combined with each other without conflict.
[0029] It should be noted that: similar labels and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.
[0030] Embodiment 1, a waterproof driving device, comprising a waterproof sleeve 102, the waterproof sleeve 102 is provided with a sealing end cover 101 at both ends, a driving motor 1 is arranged between the two sealing end covers 101 in the waterproof sleeve 102, a plurality of first sealing elements are arranged between the inner wall of the waterproof sleeve 102 and the outer surface of the sealing end cover 101, the plurality of first sealing elements are used to form multiple waterproof barriers at the connection between the sealing end cover 101 and the waterproof sleeve 102 to achieve waterproof;
[0031] The combination of the waterproof sleeve 102 and the sealing end cover 101 forms a relatively closed space in which the driving motor 1 is wrapped, and a plurality of first sealing elements play a role at the connection between the sealing end cover 101 and the waterproof sleeve 102. They cooperate with each other to form multiple waterproof barriers. The first sealing elements can fill the tiny gaps at the connection and prevent water from entering the inside of the waterproof sleeve 102 in a permeating, splashing, or other manner, thereby effectively protecting the driving motor 1.
[0032] In the embodiment 2, the waterproof driving device provided in the embodiment 1 is further optimized. Specifically, the number of first sealing elements arranged between the sealing end cover 101 and the waterproof sleeve 102 is at least two, thereby realizing multiple waterproof barriers, increasing the difficulty of water entering the inside of the waterproof sleeve 102, and improving the waterproof effect.
[0033] Further, as shown in Figures 2-3 , the first sealing element includes a waterproof sealing ring 2, which is sleeved on the outer surface of the sealing end cover 101 and in contact with the inner wall of the waterproof sleeve 102. The waterproof sealing ring 2 is made of rubber. The elasticity of the rubber enables it to deform when being extruded, thereby filling the uneven surface and tiny gaps between the sealing end cover 101 and the waterproof sleeve 102 and forming a seal.
[0034] Further, as shown in Figure 2 and Figure 3 , a sealing ring limiting groove 201 is formed on the outer surface of the sealing end cover 101, and the waterproof sealing ring 2 is inserted into the inner wall of the sealing ring limiting groove 201. The sealing ring limiting groove 201 is used to limit the waterproof sealing ring 2 and reduce its movement, thereby ensuring its stability and sealing performance during long-term use.
[0035] In the embodiment 3, the waterproof driving device provided in the embodiment 1 is further optimized. Specifically, the first sealing element is sealing glue, which is arranged between the sealing end cover 101 and the waterproof sleeve 102. The sealing glue not only seals the connection between the waterproof sleeve 102 and the sealing end cover 101, but also fixes the waterproof sleeve 102 and the sealing end cover 101 together, thereby enhancing the structural stability of the entire waterproof driving device. The sealing glue can be polyamide glue, which can be softened by heating and then removed during disassembly and maintenance.
[0036] In the embodiment 4, the waterproof driving device provided in the above embodiments is further optimized. Specifically, as shown in Figure 2As shown, the support cylinder 103 is arranged between the driving motor 1 and one of the sealing end covers 101, and the output shaft of the driving motor 1 penetrates the support cylinder 103 and the one of the sealing end covers 101 and extends to the outside of the waterproof sleeve 102 and is connected with the spline 104, which is used to connect with the roller brush of the scrubber during use, so that the driving motor 1 can drive the roller brush of the scrubber to rotate through the spline 104.
[0037] Further, a sealing bearing is arranged at the connection between the output shaft of the driving motor 1 and the sealing end cover 101, which is used for sealing the connection between the output shaft of the driving motor 1 and the sealing end cover 101 and ensuring the rotation of the output shaft of the driving motor 1.
[0038] Further, as shown in Figures 1-2 The other sealing end cover 101 is provided with a mounting seat 105 on the side away from the waterproof sleeve 102, which is used to connect with the body of the scrubber.
[0039] In embodiment 5, the waterproof driving device provided in the above embodiments is further optimized, specifically, as shown in Figures 4-5 The sealing end cover 101 is connected with the waterproof sleeve 102 through a screw, and a second sealing member is arranged between the outer surfaces of the waterproof sleeve 102 and the two sealing end covers 101, which can seal the gap between the outer surfaces of the waterproof sleeve 102 and the sealing end covers 101 and also covers the screw to reduce the corrosion of the screw in water;
[0040] The arrangement of the second sealing member further improves the waterproof performance of the overall waterproof driving device. It not only seals the gap between the outer surfaces of the waterproof sleeve 102 and the sealing end covers 101, but also covers the screw to form protection. When water contacts the waterproof driving device, it will first encounter the obstruction of the second sealing member, reducing the direct entry into the gap and contact with the screw, which effectively prevents water from penetrating from the outside to the inside of the waterproof sleeve 102, further enhances the waterproof effect, protects the internal components such as the driving motor 1, and at the same time, reduces the corrosion of the screw in water, prolongs the service life of the screw; as a key component for connecting the waterproof sleeve 102 and the sealing end cover 101, if the screw is corroded, it will cause the connection to be loose, affecting the structural stability and sealing performance of the overall waterproof driving device. Through the protection of the second sealing member, the screw is always maintained in a dry environment, maintaining a good connection state.
[0041] Further, as shown in Figures 4-5As shown, the second sealing member includes two annular grooves 302 respectively formed on the waterproof sleeve 102 and the sealing end cover 101, and a convex bead 301 is arranged in each of the two annular grooves 302, and the outer surfaces of the two convex beads 301 are fixedly connected with a sealing sleeve 3, the sealing sleeve 3 is sleeved between the outer surfaces of the waterproof sleeve 102 and the sealing end cover 101, and the sealing sleeve 3 covers the outer surface of the connection between the sealing end cover 101 and the waterproof sleeve 102, thereby improving the waterproof effect, the convex bead 301 and the annular groove 302 cooperate to limit the sealing sleeve 3, thereby improving the stability of the sealing sleeve 3 and reducing the movement of the sealing sleeve 3 in the axial direction, and the sealing sleeve 3 is also made of rubber, and the elasticity of the rubber enables the sealing sleeve 3 to cover the connection between the sealing end cover 101 and the waterproof sleeve 102.
[0042] Further, as shown in Figures 4-5 The outer surface of the waterproof sleeve 102 is fixedly sleeved with a supporting sleeve 303, and the end of the supporting sleeve 303 is in contact with the end of the sealing sleeve 3, and the supporting sleeve 303 can limit the sealing sleeve 3.
