Description

Technical Field

[0001] This utility model relates to the field of drive mechanism technology, and more specifically, to a waterproof drive mechanism. Background Technology

[0002] In the field of cleaning equipment, floor scrubbers are widely used in various occasions, such as commercial venues, homes, and industrial plants, as an efficient and convenient floor cleaning tool. The working principle of floor scrubbers is mainly to wipe and clean the floor by the high-speed rotation of the roller brush, while working with a water tank and water suction system to complete the entire cleaning process. However, when cleaning the floor, especially on wet or waterlogged floors, water can easily seep into the roller brush drive part of the floor scrubber, which may cause the motor to get damp, short-circuit, or even be damaged, thus affecting the normal operation and service life of the floor scrubber.

[0003] Traditional floor scrubber roller brush drive mechanisms often lack effective waterproofing measures or have unsatisfactory waterproofing, causing water to easily penetrate into the motor during the scrubbing process, leading to motor failure and increasing the maintenance costs of the floor scrubber. Therefore, we have made improvements and proposed a waterproof drive mechanism. Utility Model Content

[0004] The purpose of this utility model is to address the problem that existing floor scrubber roller brush drive mechanisms often lack effective waterproofing measures or have unsatisfactory waterproofing effects, which leads to water easily penetrating into the motor during the floor scrubbing process and causing motor failure.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In the scheme of this application:

[0020] To address the problem that existing floor scrubber roller brush drive mechanisms often lack effective waterproofing measures or have unsatisfactory waterproofing effects, leading to water easily penetrating into the motor during the scrubbing process and causing motor failure, this application incorporates several sealing rings between the waterproof housing and the rear and front sealing covers. These sealing rings form multiple waterproof barriers, effectively reducing water seepage through the connections between the rear and front sealing covers and the waterproof housing during scrubbing. This protects the motor from water damage. Because the motor is effectively waterproofed, the motor failure rate is significantly reduced when the floor scrubber operates on wet or flooded surfaces, thus extending its service life and improving the equipment's durability and reliability.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0030] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] Example 1, please refer to Figures 1-4 A waterproof drive mechanism includes a waterproof housing 1. A rear sealing cover 101 and a front sealing cover 102 are respectively provided at both ends of the waterproof housing 1. A drive assembly is located between the rear sealing cover 101 and the front sealing cover 102. Several sealing rings 2 are provided between the outer surfaces of the rear sealing cover 101 and the front sealing cover 102 and the inner wall of the waterproof housing 1. The sealing rings 2 are used to seal the connection between the waterproof housing 1 and the rear and front sealing covers 101 and 102. The sealing rings 2 are made of materials with good elasticity and sealing performance, such as rubber. When the sealing rings 2 are installed between the waterproof housing 1 and the rear and front sealing covers 101 and 102, they are subjected to a certain amount of compression, thereby filling the tiny gaps between them. This filling effect can effectively prevent water penetration, forming a reliable waterproof barrier, and thus achieving waterproof protection for the drive assembly.

[0033] Furthermore, the number of sealing rings 2 on the rear sealing cover 101 and the front sealing cover 102 is at least two, thereby forming multiple waterproof barriers. This effectively reduces the possibility of water seeping into the water through the connection between the rear sealing cover 101 and the front sealing cover 102 and the waterproof shell 1 during the floor cleaning process, thus improving the waterproof effect. When water attempts to seep in, each sealing ring 2 will block it, increasing the difficulty and path length of water penetration, further preventing water from penetrating deeper, thereby effectively improving the overall waterproof effect.

[0034] Furthermore, such as Figure 3As shown, both the rear sealing cover 101 and the front sealing cover 102 have positioning grooves 201 on their outer surfaces. The sealing ring 2 is inserted into the inner wall of the positioning groove 201. The design of the positioning groove 201 ensures the positional stability of the sealing ring 2, so that the sealing ring 2 can always remain in the sealing position. Because some vibration and external force are inevitably generated during installation, use and disassembly, without the limiting of the positioning groove 201, the sealing ring 2 may be displaced or twisted, thereby destroying its sealing effect. By limiting the sealing ring 2 with the positioning groove 201, this situation is effectively reduced, ensuring that the sealing ring 2 can continuously and stably play a waterproof role, and improving the reliability and stability of waterproofing.

[0035] Example 2 further optimizes the waterproof drive mechanism provided in Example 1, specifically, as follows: Figures 3-6 As shown, the drive assembly includes a motor body 103 disposed inside the waterproof housing 1. A support cylinder 108 is installed on the side of the motor body 103 near the front sealing cover 102. The output shaft of the motor body 103 passes through the support cylinder 108 and the front sealing cover 102 in sequence and is connected to a spline 105. The motor body 103 can drive the spline 105 to rotate. The spline 105 is connected to the roller brush of the floor scrubber to drive the roller brush to rotate.

[0036] A sealing bearing is provided between the output shaft of the motor body 103 and the inner wall of the front sealing cover 102. The sealing bearing is used to seal the connection between the output shaft of the motor body 103 and the front sealing cover 102. When the output shaft of the motor body 103 rotates, the sealing bearing can ensure the normal rotation of the output shaft while reducing the entry of external substances through the gap between the output shaft and the front sealing cover 102, thereby achieving a good sealing effect.

[0037] Furthermore, such as Figures 3-6 As shown, the spline 105 is provided with a mounting hole 104. The mounting hole 104 is connected to the output shaft of the motor body 103 by bolts. Bolt connection is a common and reliable detachable connection method. It has the characteristics of firm connection and convenient disassembly. By providing a mounting hole 104 on the spline 105 and a corresponding threaded hole on the output shaft of the motor body 103, the spline 105 can be connected to the output shaft after the bolts are tightened, ensuring the effective transmission of power.

[0038] Furthermore, such as Figure 3As shown, the outer surfaces of the front sealing cover 102 and the rear sealing cover 101 are provided with several limiting protrusions 106. Both ends of the waterproof shell 1 are provided with slots 107, and the inner wall of the slots 107 is inserted into the outer surface of the limiting protrusions 106. The limiting protrusions 106 and the slots 107 cooperate with each other to realize the limiting between the waterproof shell 1 and the rear sealing cover 101 and the front sealing cover 102, reduce the rotation between the waterproof shell 1 and the rear sealing cover 101 and the front sealing cover 102, and improve the stability of the structure.

[0039] Furthermore, the waterproof housing 1 is connected to the rear sealing cover 101 and the front sealing cover 102 by bolts. The bolt connection facilitates disassembly and assembly. The front sealing cover 102 is also connected to the support cylinder 108 by bolts, so that the motor body 103, the support cylinder 108 and the front sealing cover 102 can form a stable structure, improving the stability during use.

[0040] Example 3 further optimizes the waterproof drive mechanism provided in Example 1 or 2, specifically, as follows: Figure 5 and Figure 6 As shown, a positioning boss 113 is provided on the side of the support cylinder 108 near the front sealing cover 102, and a positioning groove 114 is provided on the side of the front sealing cover 102 near the support cylinder 108. The inner wall of the positioning groove 114 is inserted into the outer surface of the positioning boss 113. The insertion of the positioning boss 113 and the positioning groove 114 can connect the front sealing cover 102 and the support cylinder 108 together. This mechanical positioning method utilizes the principle of shape constraint of objects. Through the mutual nesting of the positioning boss 113 and the positioning groove 114, the relative rotation between the front sealing cover 102 and the support cylinder 108 is restricted.

[0041] Furthermore, such as Figure 3 and Figure 5 As shown, a slot 109 is provided inside the rear sealing cover 101. A limiting protrusion 110 is fixedly installed on the inner wall of the slot 109. A connecting seat 111 is inserted into the inner wall of the slot 109. One end of the connecting seat 111 is fixedly connected to the motor body 103. A limiting groove 112 is formed on the outer surface of the connecting seat 111, and the inner wall of the limiting groove 112 is inserted into the limiting protrusion 110. After the connecting seat 111 and the slot 109 are inserted together, they are used to realize the connection between the rear sealing cover 101 and the motor body 103. The insertion of the limiting protrusion 110 and the limiting groove 112 can limit the connection between the rear sealing cover 101 and the connecting seat 111 to prevent the connecting seat 111 and the rear sealing cover 101 from rotating, thereby improving the stability of the connection between the motor body 103 and the rear sealing cover 101.

[0042] Furthermore, such as Figure 3 and Figure 4As shown, a connecting rod 3 is fixedly connected to the side of the rear sealing cover 101 away from the motor body 103. A connecting shaft 301 is fixedly installed on the connecting rod 3. A mounting seat 302 is connected between the two ends of the connecting shaft 301. The wiring of the motor body 103 passes through the connecting seat 111, the rear sealing cover 101 and the connecting rod 3, and sealant is provided at the connection points of the wiring with the connecting seat 111, the rear sealing cover 101 and the connecting rod 3.

[0043] The waterproof drive mechanism provided by this utility model is used as follows:

[0044] Mounting base 302 is used to install the roller brush on the corresponding position on the floor scrubber, while the roller brush is sleeved on the outer surface of the waterproof shell 1 and connected to the spline 105. The motor body 103 drives the roller brush to rotate through the spline 105 to clean the floor.
