Description

Technical Field

[0001] The utility model relates to the technical field related to ventilators, in particular to a ventilator cleaning device. Background Art

[0002] The ventilator is mainly used to ventilate the working environment. When the ventilator works in an environment with high dust, the dust in the environment will adhere to the fan blades, and when larger dust particles pass through the rotating fan blades, the blades will crush the large dust particles to produce fine dust. The fine dust will adhere and deposit in the front and trailing edge areas of the non-working front of the blade and the trailing edge of the working surface of the blade near the rear disk of the impeller.

[0003] With the continuous use of the ventilator, the dust on its fan blades will gradually thicken due to adhesion and deposition, making subsequent cleaning more difficult. As the thickness of the dust on the fan blades gradually increases, the ventilation effect of the ventilator will gradually deteriorate. Therefore, the fan blades of the ventilator should be cleaned frequently. If the dust on the fan blades is cleaned frequently, it will affect the efficiency of the ventilator, especially when the ventilator is installed at a high place, which makes cleaning more inconvenient.

[0004] Based on the above situation, it is necessary to design a ventilator cleaning device to solve the above problems. Utility Model Content

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0024] Reference Figures 1-6 As shown, a ventilator cleaning device includes a shell 1, a driving motor 2 is provided inside the shell 1, a fan body 3 is provided at the output end of the driving motor 2, and also includes a shell 2 5 located at the output end of the fan body 3 and connected to one end of the shell 1, a plurality of air nozzles 4 arranged at the output and input ends of the fan body 3, and an air pump 6 arranged inside the shell 2 5, wherein the plurality of air nozzles 4 are equidistantly arranged around the central axis of the shell 1, so that the air nozzles 4 can blow air to the fan body 3 from various angles when in use, and the output direction of the air nozzles 4 is toward the fan body 3, and the air pump 6 delivers high-pressure gas to the air nozzles 4 through the air guide pipe. When the ventilator is installed, the shell 2 5 is connected to the shell 1, and then when the fan body 3 is driven by the driving motor 2 When the fan body 3 rotates and starts ventilation operation, the dust in the air will adhere to the blades of the fan body 3. If the fan body 3 needs to be cleaned, the speed of the fan body 3 is slowed down or the fan body 3 is stopped, and then the air pump 6 is started. The air pump 6 will transport the gas in a compressed state through the air guide pipe to the input end of each air nozzle 4, and then blow it out through the output end of the air nozzle 4. After the accelerated flow of gas flows to the high-pressure air nozzle 4, it is affected by the internal structure of the air nozzle 4, making the gas become a high-impact airflow. When the gas is acted on the blades of the fan body 3, the dust attached to the blades will be blown away. Then, after the fan body 3 resumes the high-speed ventilation state, the dust that has fallen will be blown out by the fan body 3 along with other air.

[0025] The dust on the fan body 3 is removed by blowing air. Compared with the problem of rusting of the fan body 3 caused by using water to clean, the gas cleaning can remove the dust without damaging the fan body 3. Since the device structure is connected to the ventilator, the fan body 3 can be cleaned frequently. When the dust is just attached to the fan body 3, its adhesion force is small, so it can be blown away by the high-pressure gas. Moreover, due to the large number of cleaning times, it is ensured that dust will not be deposited on the fan body 3, and when the fan body 3 rotates at a low speed, it will not affect the use of the device structure. It can also ensure that the dust blown off the fan body 3 will be blown out of the outer shell 1 and the outer shell 2 5 as the fan body 3 fanns.

[0026] Among them, in order to enable the air nozzles 4 respectively surrounding the outer shell 1 and the outer shell 2 5 to effectively receive the airflow, the air guide pipe includes an annular tube 1 7 connected to the outer wall of the outer shell 1, an annular tube 2 8 connected to the outer wall of the outer shell 2 5, and an air guide pipe 1 9 connecting the annular tube 2 8 with the output end of the air pump 6, and an air guide pipe 2 10 is connected between the annular tube 1 7 and the annular tube 2 8. The annular tube 7 and the annular tube 2 8 are both connected to the air nozzle 4. When in use, the air pump 6 transports the gas into the annular tube 1 7, and then flows into the interior of the annular tube 2 8 through the air guide pipe 1 9, and then is introduced into the air nozzles 4 connected to each other.

[0027] Furthermore, a three-way valve 11 is provided on the air duct 2 10, one of the ports of the three-way valve 11 is connected to the output end of the air duct 1 9, and the other two ports of the three-way valve 11 are connected to the annular tube 1 7 and the annular tube 2 8 respectively. The setting of the three-way valve 11 can prevent the gas output by the air pump 6 from being excessively dispersed, thereby ensuring the high impact force of the gas. Specifically, when the three-way valve 11 connects the air duct 2 10 with the annular tube 1 7, the gas output by the air pump 6 will be output by the air nozzle 4, thereby cleaning one side of the fan body 3. When the three-way valve 11 connects the air duct 2 10 with the annular tube 2 8, the gas output by the air pump 6 will be output by the air nozzle 4, thereby cleaning the other side of the fan body 3. During this period, it is ensured that the gas output by the air pump 6 will not be excessively diverted. In addition, according to actual usage, the three-way valve 11 can be disabled so that the gas of the air pump 6 can be output through the air nozzle 4.

[0028] Among them, the output directions of several air nozzles 4 toward the fan body 3 are all different, so that each position of the blades of the fan body 3 can be impacted by high-pressure gas. According to actual usage, when installing the air nozzle 4, the output direction of the air nozzle 4 can be appropriately adjusted to better achieve the above effect.

[0029] Furthermore, the interior of the outer shell 2 5 is connected to a protective shell 12 with an opening at one end. The end of the protective shell 12 away from the opening has a certain streamline to ensure that the flow of air is not obstructed. The air pump 6 is arranged in the protective shell 12, and the end of the protective shell 12 close to the fan body 3 is provided with an annular tube 3 13, and the annular tube 3 13 is provided with several air nozzles 3 130. The output end of the air nozzle 3 130 faces the fan body 3, and the annular tube 3 13 is connected to the output end of the air pump 6. When the air pump 6 is used to deliver gas to the air nozzle 3 130, the air nozzle 3 130 can clean the dust near the axis position of the fan body 3. When the gas blown out by the air nozzle 4 acts on the fan body 3 near the axis position, the impact force of the gas will be weakened. Therefore, the use of the air nozzle 3 130 can avoid the situation where the dust at this position is not cleaned in place.

[0030] Furthermore, since the air pump 6 needs to continuously inhale gas when it is running, in order to prevent the dust in the gas around the air pump 6 from drying into the operation of the air pump 6, a ring plate 14 is fixedly connected to the open end of the protective shell 12, and a filter member 15 is provided in the ring plate 14. The gas will first pass through the filter member 15 to filter out the dust therein before being inhaled by the air pump 6. The gas output by the air pump 6 is clean gas, which also avoids clogging the air nozzle 4 and affecting the use of the air nozzle 4.

[0031] Furthermore, if the dust content in the operating environment of the air pump 6 is large, more dust will be attached to the filter screen, which will affect the use of the air pump 6. Therefore, a motor 16 is connected to the ring plate 14, and a scraper 17 is connected to the output end of the motor 16. The scraper 17 is in contact with the surface of the filter element 15. The motor 16 drives the scraper 17 to operate, and the scraper 17 will remove the dust on the filter element 15. The removed dust will be blown away with the output of the ventilator.
