[0002] Cleaning equipment, such as floor scrubbers, is a device for cleaning floors and is suitable for cleaning large commercial spaces, such as shopping malls, restaurants, and stations.

[0003] Because floor scrubbers and other cleaning equipment need to clean large areas and operate for extended periods, the motor temperature rises during operation, requiring heat dissipation. Current technology typically involves adding a fan to the motor and creating ventilation holes in the casing to cool it. However, during operation, water inevitably splashes everywhere, and this water may enter the equipment through the ventilation holes, accumulating at the bearings or flowing along the output shaft into the gearbox. Over time, this can cause rust on the motor output end, bearings, and even the gearbox, affecting the normal operation and lifespan of the cleaning equipment. Utility Model Content

[0004] This utility model aims to provide a drive device and cleaning equipment for cleaning equipment. The fan design can prevent water or water vapor from entering the bearing, thus avoiding rust and affecting the use of the bearing.

[0023] To make the objectives and technical solutions of the present utility model embodiments clearer, the following will be described in conjunction with the accompanying drawings of the present utility model embodiments. Figure 1 -Appendix Figure 4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] In this utility model, for clarity, the following description is provided: [The observer faces the attached...] Figure 1 Observe the up and down directions as indicated in the instruction manual. Figure 1 The vertical direction is taken as the reference. The above description is only for the purpose of clearly describing this utility model, and is not intended to indicate or imply that the structure or component referred to must have a specific orientation or be constructed in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] like Figure 1 As shown, the driving device 1 provided by this utility model is applied in cleaning equipment, especially floor scrubbers, to drive the cleaning equipment to work, and has heat dissipation and waterproof functions.

[0026] The cleaning equipment includes a drive unit 1, a reduction gearbox 2, and a brush disc 3. The drive unit 1 is meshed with the reduction gearbox 2, and the brush disc 3 is connected to the reduction gearbox 2. The drive unit 1 drives the reduction gearbox 2 to work, and the reduction gearbox 2 drives the brush disc 3 to work.

[0027] like Figure 2 As shown, the drive device 1 includes a motor 11, an output shaft 12, and a fan 13. The output end of the motor 11 is connected to the output shaft 12, and the fan 13 is mounted on the output shaft 12. The motor 11 drives the output shaft 12 to rotate, and the fan 13 rotates with the output shaft 12. The fan 13 rotates and cuts the air, driving air circulation to cool the motor 11 and the output shaft 12.

[0028] Specifically, the reduction gearbox 2 is meshed with the end of the output shaft 12, the reduction gearbox 2 is connected to the brush disc 3, the motor 11 drives the reduction gearbox 2 to work through the output shaft 12, and the reduction gearbox 2 drives the brush disc 3 to rotate and sweep the ground.

[0029] like Figure 2 As shown, the fan 13 includes a shaft portion 131, a first fan frame 132, a second fan frame 133, and blades 134. The shaft portion 131 is mounted on the output shaft 12. The first fan frame 132 is located above the second fan frame 133. The first fan frame 132 and the second fan frame 133 have the same radial length. A plurality of evenly distributed blades 134 are installed between the first fan frame 132 and the second fan frame 133. The end of the blade 134 is connected to the shaft portion 131, and the other end of the blade 134 extends to the edge of the first fan frame 132 and the second fan frame 133.

[0030] Specifically, the first fan frame 132 has a hollow structure, such as the annular structure shown in the figure. The first fan frame 132 is fixed to the end of the blade 134 away from the shaft 131. When the fan 13 is working, air flows upward through the hollow structure of the first fan frame 132 to cool the motor 11. The second fan frame 133 is connected to the shaft 131 and is fixed to the lower end of the blade 134.

[0031] Furthermore, such as Figure 2As shown, the second fan frame 133 includes a first surface 1331 and a second surface 1332, which are connected to each other. The first surface 1331 is connected to the shaft portion 131, and the second surface 1332 is away from the shaft portion 131. The first surface 1331 is a plane or a slope, and the second surface 1332 is a slope. The end of the second surface 1332 near the shaft portion 131 is higher than the end away from the shaft portion 131. Water droplets enter the fan 13 and flow down along the second surface 1332.

[0032] Specifically, when the first surface 1331 is a slope, the direction of inclination is the same as that of the second surface 1332. like Figure 3 As shown, the drive device 1 also includes a cover 14, which is fitted on the outside of the output shaft 12. One end of the cover 14 is connected to the housing of the motor 11, and the other end of the cover 14 wraps around the end of the output shaft 12. The cover 14 is connected to the housing of the gearbox 2, and the cover 14 can be integrally formed with the housing of the gearbox 2.

[0033] Specifically, a heat dissipation space is formed between the inner wall of the housing 14 and the end of the motor 11. The fan 13 rotates and drives the air flow in the heat dissipation space. The accelerated air flows through the output end of the motor 11 and the output shaft 12, and carries away heat through convection, thereby improving the heat dissipation effect.

[0034] The drive device 1 further includes a bearing 15 and a seal 16. The bearing 15 is mounted on the output shaft 12 and is located between the housing 14 and the output shaft 12. The bearing 15 supports the output shaft 12, ensuring its relative position and rotational accuracy, and ensuring smooth and stable rotation. The seal 16 is mounted on the outside of the output shaft 12 and is placed inside the housing 14, below the bearing 15. The seal 16 prevents moisture from entering the end of the output shaft 12 and affecting its transmission.

[0035] Specifically, the radial length of the second fan frame 133 is greater than the radial length of the bearing 15 to prevent water droplets from dripping into the bearing 15 along the second surface 1332.

[0036] like Figure 2As shown, the housing 14 includes a transmission groove 141, a side wall 142, and a water collection groove 143. The bottom of the housing 14 is recessed to form the transmission groove 141, and the end of the output shaft 12 is placed in the transmission groove 141. The side wall 142 is connected to the housing of the motor 11, and the lower end of the side wall 142 forms the water collection groove 143 between it and the outer wall of the transmission groove 141, which is used to collect water droplets and discharge them.

[0037] like Figure 3 As shown, the housing 14 also includes a water baffle 144, which is formed by the upward extension of the wall of the transmission groove 141. The water baffle 144 is higher than the installation position of the bearing 15 and is used to prevent water from splashing into the bearing 15.

[0038] like Figure 3 As shown, the housing 14 further includes a first step 145 and a second step 146. The first step 145 and the second step 146 are disposed on the inner wall of the transmission groove 141. The first step 145 is located above the second step 146. The bearing 15 is placed on the first step 145, and the seal 16 is placed on the second step 146. The first step 145 and the second step 146 are respectively used to position and install the bearing 15 and the seal 16.

[0039] like Figure 1 As shown, the cover 14 also includes heat dissipation vents 147. Multiple heat dissipation vents 147 are evenly distributed on the side wall 142. The fan 13 is at the same height as the heat dissipation vents 147. When the fan 13 rotates, external air and internal air circulate and exchange through the heat dissipation vents 147.

[0040] like Figure 2 As shown, the cover 14 also includes a drain outlet 148. A plurality of drain outlets 148 are opened on the bottom surface of the water collection tank 143. Water droplets fall into the water collection tank 143 and are discharged from the cover 14 through the drain outlets 148.

[0041] Specifically, the bottom surface of the water collection tank 144 is preferably designed as a slope, with the bottom surface portion near the drain outlet 148 being lower than the bottom surface portion away from the drain outlet 148.

[0042] like Figure 4 As shown, the housing 14 also includes a mounting portion 149, which is symmetrically arranged on the side wall 142. The drive device 1 also includes a mounting rod 17, which connects the motor 11 and the housing 14. One end of the mounting rod 17 is fixed to the mounting portion 149, and the other end of the mounting rod 17 extends into the motor 11 and is fixed to the end cover of the motor 11.

[0043] The working process of the drive device 1 is as follows: the motor 11 drives the output shaft 12 to rotate, the output shaft 12 drives the fan 13 to rotate, the fan 13 accelerates the air circulation, and removes the heat from the end of the motor 11 and the output shaft 12. During the rotation, the fan 13 generates negative pressure to draw in water or water vapor. Most of the water or water vapor is thrown out through the heat dissipation port 147, and a small amount of water or water vapor enters the fan 13 or is ejected into the water collection tank 143. Water entering the fan 13 flows into the water collection tank 143 along the first surface 1331 and the second surface 1332. Water hitting the side wall 142 or the bottom surface of the water collection tank 143 may splash towards the bearing 15. The baffle plate 144 blocks the water droplets flying towards the bearing 15, and the water droplets bounce back into the water collection tank 143. The baffle plate 144 prevents water droplets from entering the bearing 15. Water falling into the water collection tank 143 flows out from the drain port 148. The seal 16 can further prevent water falling into the bearing 15 from entering the gearbox 2 along the output shaft 12. A very small amount of water falling into the bearing 15 can also evaporate quickly, avoiding water accumulation on the bearing 15 and effectively preventing the bearing 15 from rusting. The present invention provides a drive device for cleaning equipment. Through the structure of a fan and a baffle plate, the drive device effectively prevents water or water vapor from entering the bearing and causing it to rust. The water flows into the water collection tank and is discharged from the drain outlet, which improves the waterproof capability of the drive device and extends the service life of the drive equipment. Furthermore, the combination of the fan and the heat dissipation vent can effectively accelerate the air circulation inside the drive device, cool the motor end and the output shaft, and improve the cooling capability.

[0044] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
