Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a driving device for cleaning equipment and a cleaning equipment. Background Technology

[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 water may enter the equipment through these vents. If this water accumulates inside the casing and cannot be drained promptly, it will generate a large amount of moisture, causing rust on the motor's output end, output shaft, and bearings, thus affecting the normal operation and lifespan of the cleaning equipment. Utility Model Content

[0004] The present invention aims to provide a drive device and a cleaning device for cleaning equipment. By designing a water collection tank, accumulated water is guided to be discharged in a timely manner, so as to avoid water and moisture remaining inside the drive device for a long time, which would cause the components to rust.

[0005] To achieve the above objectives, the present invention provides a driving device for cleaning equipment, comprising a motor, an output shaft, a fan, and a housing. The output end of the motor is connected to the output shaft, and the fan is mounted on the output shaft. One end of the housing is connected to the outer casing of the motor, and the other end covers the end of the output shaft. The housing includes a side wall, a water collection trough, and a drain outlet. The side wall is connected to the outer casing of the motor, and the lower end of the side wall forms the water collection trough with the bottom surface of the housing. The bottom surface of the water collection trough is sloping, and multiple drain outlets are provided on the bottom surface of the water collection trough. The water collection trough collects and guides water droplets to be discharged from the drain outlets from the housing.

[0006] In a preferred embodiment of this utility model, the water collection tank is divided into a first tank and a second tank, and the drain outlet includes a first drain outlet and a second drain outlet. The first drain outlet is opened on the bottom surface of the first tank, and the second drain outlet is opened on the bottom surface of the second tank. In a preferred embodiment of the present invention, the bottom surfaces of the first trough and the second trough are sloping surfaces, and the portion of the bottom surface of the first trough near the first drain outlet is lower than the portion far from the first drain outlet; the portion of the bottom surface of the second trough near the second drain outlet is lower than the portion far from the second drain outlet. In a preferred embodiment of this utility model, the cover is connected to the gearbox of the cleaning equipment, the bottom surface of the cover partially overlaps with the top surface of the gearbox, the first groove is the side connected to the gearbox, the second groove is the side away from the gearbox, the bottom area of ​​the first groove is larger than the area of ​​the water collection groove overlapping with the top surface of the gearbox, and the first drain outlet is opened in a non-overlapping position. In a preferred embodiment of the present invention, the slope inclination angle of the first groove and the second groove is greater than the sway angle of the drive device installed in the cleaning equipment.

[0007] In a preferred embodiment of the present invention, the housing includes a transmission groove, the bottom of the housing is recessed to form the transmission groove, and the end of the output shaft is placed in the transmission groove.

[0008] In a preferred embodiment of the present invention, the driving device further includes a bearing and a seal, the bearing and the seal being fitted onto the outside of the output shaft and located in the transmission groove, the seal being located below the bearing.

[0009] In a preferred embodiment of the present invention, the cover further includes a baffle plate, the outer wall of the transmission groove extends upward to form the baffle plate, and the upper edge of the baffle plate is higher than the installation position of the bearing. In a preferred embodiment of the present invention, the cover further includes heat dissipation vents, and a plurality of heat dissipation vents are disposed on the side wall, with the fan at the same height as the heat dissipation vents.

[0010] This utility model also provides a cleaning device, including a driving device for cleaning devices as described in any one of the above claims. The cleaning device further includes a gearbox and a brush disc. The driving device is meshed with the gearbox, and the brush disc is connected to the gearbox. The driving device drives the brush disc to rotate through the gearbox.

[0011] This utility model provides a drive device for cleaning equipment. By setting a water collection tank to collect water droplets entering the device and setting the bottom of the water collection tank at an inclined angle, the water droplets are guided to flow along the slope to the first or second drain outlet. This effectively avoids the risk of rust caused by water droplets remaining in the water collection tank and a large amount of water vapor remaining. At the same time, the structural design of the fan and water baffle effectively prevents water or water vapor from entering the bearings and causing rust, thus extending the service life of the drive device.

[0019] 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 5 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.

[0020] 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.

[0021] The present invention provides a driving device 1 for use in cleaning equipment, especially floor scrubbers, for driving the cleaning equipment to work, and has heat dissipation and waterproof functions.

[0022] like Figure 1 As shown, 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.

[0023] like Figure 2 As shown, the drive device 1 includes a motor 11, an output shaft 12, a fan 13, and a housing 14. The output end of the motor 11 is connected to the output shaft 12. 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 housing 14 is mounted on the outside of the output shaft 12. One end of the housing 14 is connected to the housing of the motor 11, and the other end of the housing 14 covers the end of the output shaft 12. A heat dissipation space is formed between the inner wall of the housing 14 and the end of the motor 11. The rotating fan 13 cuts through the air, causing the air in the heat dissipation space to flow. The accelerated airflow passes over the output end of the motor 11 and the output shaft 12, carrying away heat through convection, thereby improving the heat dissipation effect and cooling the air. 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 cover 14 is connected to the housing of the reduction gearbox 2, 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.

[0024] Furthermore, such as Figure 3 As shown, the bottom surface of the cover 14 partially overlaps with the top surface of the gearbox 2, and the overlapping area is less than 1 / 2 of the area of ​​the bottom surface of the cover 14. The cover 14 can be integrally formed with the housing of the gearbox 2.

[0025] like Figure 2 As shown, the housing 14 includes a transmission groove 141, a side wall 142, a water collection groove 143, and a drain outlet 144. 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. 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. The bottom surface of the water collection groove 143 is a slope. Multiple drain outlets 144 are arranged on the bottom surface of the water collection groove 143. The water collection groove 143 is used to collect water droplets so that the accumulated water is discharged from the drain outlets 144.

[0026] like Figure 3 As shown, the water collection tank 143 is divided into a first tank 1431 and a second tank 1432. The first tank 1431 is the side connected to the gearbox 2, and the bottom area of ​​the first tank 1431 is larger than the area where the bottom of the water collection tank 143 overlaps with the top surface of the gearbox 2. The second tank 1432 is the side away from the gearbox 2. The drain outlet 144 includes a first drain outlet 1441 and a second drain outlet 1442. The first drain outlet 1441 is opened on the bottom surface of the first tank 1431, and the first tank 1431 partially overlaps with the housing of the gearbox 2. The first drain outlet 1441 is opened in the part where the two do not overlap, that is, near the axis. The second drain outlet 1442 is opened in the second tank 1432. The shape and size of the second drain outlet 1442 are designed according to actual needs. For example, as shown in the figure, the second drain outlet 1442 can be composed of multiple concentric arc-shaped holes of the same shape but different sizes.

[0027] Specifically, the bottom surfaces of the first trough 1431 and the second trough 1432 are sloped surfaces. The portion of the bottom surface of the first trough 1431 near the first drain outlet 1441 is lower than the portion away from the first drain outlet 1441. The bottom surface of the second trough 1432 may have multiple slopes. The portion of the bottom surface of the second trough 1432 near the second drain outlet 1442 is lower than the portion of the bottom surface away from the second drain outlet 1442.

[0028] Furthermore, since the drive device 1 has a sway angle when installed in the cleaning equipment, the bottom inclination angle of the first groove 1431 and the second groove 1432 must be greater than the sway angle.

[0029] Specifically, when water droplets fall into the water collection tank 143, the water droplets flow along the slopes of the first tank 1431 and the second tank 1432 to the first drain outlet 1441 and the second drain outlet 1442 and are discharged.

[0030] like Figure 1 As shown, the cover 14 also includes heat dissipation vents 145. Multiple heat dissipation vents 145 are evenly distributed on the side wall 142. The fan 13 is at the same height as the heat dissipation vents 145. When the fan 13 rotates, external air and internal air circulate and exchange through the heat dissipation vents 145.

[0031] 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.

[0032] like Figure 4 As shown, the cover 14 also includes a water baffle 146, which is formed by the upward extension of the wall of the transmission groove 141. The water baffle 146 is higher than the installation position of the bearing 15 and is used to prevent water from splashing into the bearing 15.

[0033] like Figure 4 As shown, the housing 14 further includes a first step 147 and a second step 148. The first step 147 and the second step 148 are disposed on the inner wall of the transmission groove 141. The first step 147 is located above the second step 148. The bearing 15 is placed on the first step 147, and the seal 16 is placed on the second step 148. The first step 147 and the second step 148 are respectively used to position and install the bearing 15 and the seal 16.

[0034] like Figure 5 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.

[0035] 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.

[0036] 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.

[0037] Furthermore, such as Figure 2 As 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.

[0038] Specifically, when the first surface 1331 is a slope, the direction of inclination is the same as that of the second surface 1332. 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.

[0039] 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 145, 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 146 blocks water droplets flying towards the bearing 15, and the water droplets bounce back into the water collection tank 143. The baffle plate 146 prevents water droplets from entering the bearing 15. Water falling into the water collection tank 143 flows out from the first drain outlet 1441 and the second drain outlet 1442 along the slope of the first groove 1431 and the second groove 1432. 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 or staying in the water collection tank 143 can also evaporate quickly, avoiding water accumulation and moisture retention inside the cover 14, effectively preventing the motor 11, the output shaft 12 and the bearing 15 from rusting. This utility model provides a drive device for cleaning equipment. By setting a water collection tank to collect water droplets entering the device and setting the inclination angle of the bottom surface of the water collection tank, the water droplets are guided to flow along the slope to the first or second drain outlet. This effectively avoids the risk of rust caused by water droplets remaining in the water collection tank and a large amount of water vapor remaining. At the same time, the structural design of the fan and water baffle effectively prevents water or water vapor from entering the bearings and causing rust, thus extending the service life of the drive device. Furthermore, by setting a fan and heat dissipation vents, the air circulation inside the drive device is effectively accelerated, improving the cooling capacity.
