Description

Technical Field

[0001] This utility model relates to a ventilation device for a cleaning machine, belonging to the field of ventilation technology for cleaning machines. Background Technology

[0002] A cleaning machine is a device used to flush out contaminants generated or introduced into a hydraulic system during manufacturing, assembly, use, and maintenance. Through its design, the cleaning machine can effectively remove dirt in various application scenarios, including but not limited to oil stains on the surface of parts. It achieves cleaning and disinfection through high-temperature steam or high-pressure water jets. Cleaning machines are generally equipped with ventilation openings to ensure ventilation.

[0003] However, when cleaning some high-temperature objects, a certain amount of hot air will be generated inside the cleaning machine. Or when cleaning objects with hot water, a large amount of hot air will also be generated inside the cleaning machine. The existing ventilation openings are directly connected to the outside. When a large amount of hot air is discharged, it can easily affect the equipment and staff around the cleaning machine. In addition, the hot air is mixed with dust and debris from the objects after cleaning. The dust and debris will adhere to the equipment near the cleaning machine along with the hot air.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 This utility model provides a technical solution: a ventilation device for a cleaning machine, including a body 1, a heater 2 fixedly connected to one side of the body 1, a water inlet pipe 7 fixedly connected to the water inlet end of the heater 2, and an exhaust mechanism 3 provided around the water inlet pipe 7; two mounting plates 13 fixedly connected to the center of the upper end of the body 1, a motor 6 fixedly connected between the two mounting plates 13, a cleaning mechanism 5 provided at the output end of the motor 6, an air extraction mechanism 4 provided at the bottom end of the cleaning mechanism 5, the bottom end of the air extraction mechanism 4 being located inside the body 1, an air collecting cylinder 10 provided on the outer side of the upper end of the air extraction mechanism 4, and a cavity 15 provided inside the air collecting cylinder 10; a filter cylinder is provided on one side of the motor 6. 9. The filter cartridge 9 is fixedly connected to the body 1. A filter screen 14 is fixedly connected inside the filter cartridge 9. The cleaning mechanism 5 is inserted into the filter cartridge 9 on one side, corresponding to the filter screen 14. The filter cartridge 9 and the cavity 15 are connected by a vent pipe 11. An air pump 8 is provided on one side of the filter cartridge 9. The air pump 8 is fixedly connected to the body 1. The air pump 8 and the filter cartridge 9 are fixedly connected by a connecting pipe 12. The air outlet of the air pump 8 is connected to one side of the exhaust mechanism 3. The cold water inside the water inlet pipe 7 cools the hot air in the heat conduction pipe 32, thereby preventing the hot air with excessive temperature from being directly discharged and affecting the equipment and personnel around the body 1.

[0019] The exhaust mechanism 3 includes a mounting block 31, a heat-conducting pipe 32, an exhaust pipe 33, and a delivery pipe 34. The mounting block 31 is fixedly sleeved on the outside of the water inlet pipe 7. A heat-conducting pipe 32 is fixedly connected to one side of the mounting block 31. The heat-conducting pipe 32 is spirally sleeved around the outside of the water inlet pipe 7, with the inner side of the heat-conducting pipe 32 tightly fitted to the outer side of the water inlet pipe 7. The end of the heat-conducting pipe 32 away from the mounting block 31 is fixedly connected to the exhaust pipe 33, and the end of the heat-conducting pipe 32 near the mounting block 31 is fixedly connected to the delivery pipe 34. The end of the delivery pipe 34 away from the heat-conducting pipe 32 is fixedly connected to the air outlet of the air pump 8. The filtered hot air is discharged through the delivery pipe 34, the heat-conducting pipe 32, and the exhaust pipe 33, while the heat-conducting pipe 32 is coiled around the outside of the water inlet pipe 7. The system uses cold water inside the inlet pipe 7 to cool the hot air inside the heat pipe 32, thus preventing excessively hot air from being directly discharged and affecting the equipment and personnel around the machine body 1. The cleaning mechanism 5 includes a worm gear 51, a connecting rod 53, a worm 52, and a cleaning brush 54. The worm gear 51 is fixedly sleeved on the outside of the output end of the motor 6. The worm 52 is meshed with one side of the worm gear 51. The two ends of the worm 52 are rotatably connected to two mounting plates 13 respectively. One end of the connecting rod 53 is fixedly connected to one end of the worm 52. The other end of the connecting rod 53 is movably inserted into the filter cylinder 9 and fixedly connected to the center position of the cleaning brush 54. One side of the cleaning brush 54 is tightly fitted to the outside of the filter screen 14. When the motor 6 starts, the worm gear 51 cools the hot air inside the heat pipe 32, thus preventing the excessively hot air from being directly discharged and affecting the equipment and personnel around the machine body 1. The wheel 51 and worm gear 52 synchronously drive the connecting rod 53 to rotate, thereby causing the cleaning brush 54 to rotate outside the filter screen 14. The cleaning brush 54 cleans the dust and debris attached to the filter screen 14, ensuring ventilation efficiency. The air extraction mechanism 4 includes two air extraction ports 41, a rotating rod 42, two connecting pipes 43, and several air outlets 44. The top of the rotating rod 42 is fixedly connected to the worm wheel 51. The rotating rod 42 passes through the air collection cylinder 10 and the top wall of the machine body 1. The rotating rod 42 is rotatably connected to the air collection cylinder 10 and the top wall of the machine body 1. The inside of the rotating rod 42 is hollow. Connecting pipes 43 are fixedly connected to both sides of the bottom end of the rotating rod 42. Air extraction ports 41 are fixedly connected to the bottom ends of the two connecting pipes 43. The upper end of the rotating rod 42 is located at... Several air vents 44 are provided inside the cavity. Hot air inside the machine body 1 enters the rotating rod 42 through the air extraction port 41 and the connecting pipe 43. The hot air inside the rotating rod 42 then enters the air collection cylinder 10 through the air vents 44, thereby dissipating the heat inside the machine body 1. At the same time, the motor 6 drives the rotating rod 42 to rotate, thereby causing the two air extraction ports 41 to rotate inside the machine body 1, increasing the air extraction range of the two air extraction ports 41 and ensuring the exhaust effect. The length of the cleaning brush 54 is adapted to the diameter of the filter screen 14, and the center position of the cleaning brush 54 corresponds to the center point of the filter screen 14, ensuring that the cleaning brush 54 and the filter screen 14 are adapted to each other, thereby ensuring the cleaning effect of the cleaning brush 54 on the dust and debris on the filter screen 14.

[0020] Specifically, in use, cold water enters the heater 2 through the inlet pipe 7, and the heater 2 heats the cold water. The heated water is then delivered to the rinsing mechanism inside the machine body 1 to rinse the object. During the rinsing process, a large amount of hot air is generated inside the machine body 1. The air pump 8 draws air from the air collection cylinder 10 through the vent pipe 11 and the connecting pipe 43, creating a negative pressure inside the air collection cylinder 10. This causes the hot air inside the machine body 1 to enter the rotating rod 42 through the air extraction port 41 and the connecting pipe 43. The hot air in the rotating rod 42 then enters the air collection cylinder 10 through the air outlet 44, thereby dissipating the heat inside the machine body 1. At the same time, the motor 6 drives the rotating rod 42 to rotate, causing the two air extraction ports 41 to rotate inside the machine body 1, thus increasing the number of air extraction ports 41. The exhaust range is wide enough to ensure effective exhaust. Before being discharged, the heat passes through the filter screen 14 inside the filter cylinder 9. Dust and debris in the hot air are trapped on the filter screen 14. When the motor 6 starts, it drives the connecting rod 53 to rotate synchronously through the worm gear 51 and worm 52, so that the cleaning brush 54 rotates on the outside of the filter screen 14. The cleaning brush 54 cleans the dust and debris attached to the filter screen 14, ensuring ventilation efficiency. The filtered hot air is discharged through the conveying pipe 34, the heat conduction pipe 32 and the exhaust pipe 33. The heat conduction pipe 32 is coiled around the water inlet pipe 7. The cold water inside the water inlet pipe 7 cools the hot air in the heat conduction pipe 32, thereby preventing the hot air with excessive temperature from being discharged directly and affecting the equipment and personnel around the machine body 1.
