Description

Technical Field

[0001] The utility model relates to the technical field of air coolers, in particular to an air outlet filter device for an air cooler. Background Art

[0002] The air cooler, also known as the water-cooled fan, is an evaporative cooling and ventilation unit that combines cooling, ventilation, dust prevention and deodorization. It is composed of a motor, a fan impeller, a water curtain shell and a fan with an air inlet and an air outlet. A water nozzle and a sewage pipe are also provided on the fan. The air outlet of the air outlet is located in a dust collecting hood with a reflective cap at the bottom. The dust collecting hood is connected to the fan, and the water outlet of the water nozzle corresponds to the impeller, so that the air cooler has a simple structure, small size, low noise, and can fully mix the gas and water into atomization to achieve the purpose of cooling and removing dust particles and harmful substances in the gas.

[0003] When some existing air coolers are in use, in order to prevent external impurities from entering the air outlet, a filter is set at the air outlet. However, when the filter is filtering dust for a long time, dust is easily accumulated on the filter, which causes the filter to be blocked, thereby affecting the air outlet effect of the air cooler.

[0004] In view of the above problems, an air outlet filter device for an air cooler is proposed. Utility Model Content

[0009] Preferably, a pulley is fixedly sleeved on the threaded rod, a pulley is also fixedly sleeved on the rotating shaft, and belts are transmission-connected to the two pulleys.

[0010] Preferably, a sealing shell is fixedly mounted on the bottom of the lifting plate, and the sealing shell is movably connected to the surface of the rotating shaft.

[0011] Preferably, a slideway is provided inside the sealing shell, and a slip ring is slidably connected inside the slideway.

[0012] Preferably, an elastic spring is fixedly installed inside the slideway, the upper end of the elastic spring is fixedly connected to one side of the slip ring, and a sealed inner shell is fixedly installed on the slip ring, which slides through the inner wall of the sealed outer shell and extends to the outside of the sealed outer shell.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The air outlet filter device of the air cooler rotates the cleaning brush to clean the dust filtered by the filter, thereby preventing the dust from accumulating on the filter and causing the filter to be blocked, thereby improving the protection of the filter, thereby reducing the phenomenon of unsmooth air outlet, maximizing the use effect of the air cooler body, and reducing the blockage of the filter by dust.

[0016] (2) The air outlet filter device of the air cooler allows the slip ring to slide inside the slideway and squeeze the elastic spring, thereby making it easier for the bottom of the sealed inner shell to contact the top of the air cooler body, thereby facilitating the protection of the air outlet cover when the air cooler body is not working, thereby preventing external impurities from falling on the filter net, thereby improving the protection effect of the air cooler body and avoiding damage to the air cooler body.

[0017] (3) The air outlet filter device of the air cooler facilitates the sliding and resetting of the sealed inner shell inside the sealed outer shell by means of the arrangement of the elastic spring and the sealed inner shell. When the sealed inner shell contacts the top of the air cooler body, the elastic force of the elastic spring causes the sealed inner shell to always contact the top of the air cooler body, thereby improving the sealing effect.

[0027] By setting the filter 3, the air outlet hood 2 is protected, thereby preventing dust from entering the interior of the air outlet hood 2, reducing the probability of dust entering the interior of the air cooler body 1, thereby improving the protection of the air cooler body 1 and improving the dustproof effect of the air cooler body 1.

[0028] Start the driving motor 8, so that the driving motor 8 drives the threaded rod 9 to rotate, and then drives the pulley 15 on the threaded rod 9 to rotate, and then drives the rotating shaft 4 to rotate through the belt 16 and another pulley 15, so that the cleaning brush 5 rotates, and the cleaning brush 5 cleans the dust filtered by the filter 3, thereby preventing dust from accumulating on the filter 3 and causing clogging of the filter 3, thereby improving the protection of the filter 3, and thereby reducing the phenomenon of unsmooth air outlet, thereby maximizing the use effect of the air cooler body 1 and reducing the clogging of the filter 3 by dust.

[0029] A sealed shell 6 is fixedly installed at the bottom of the lifting plate 11, and the sealed shell 6 is movably connected to the surface of the rotating shaft 4. A slideway 19 is opened inside the sealed shell 6, and a slip ring 17 is slidably connected inside the slideway 19. An elastic spring 18 is fixedly installed inside the slideway 19, and the upper end of the elastic spring 18 is fixedly connected to one side of the slip ring 17. A sealed inner shell 7 is fixedly installed on the slip ring 17, and the sealed inner shell 7 slides through the inner wall of the sealed shell 6 and extends to the outside of the sealed shell 6.

[0036] When the threaded rod 9 rotates, the lifting plate 11 is restricted by the rotating shaft 4, so that the sealed outer shell 6 and the lifting plate 11 move downward. When the rotating shaft 4 contacts the top of the air cooler body 1, the sealed inner shell 7 slides toward the inside of the sealed outer shell 6, and the slip ring 17 slides inside the slideway 19 and squeezes the elastic spring 18, so that the bottom of the sealed inner shell 7 contacts the top of the air cooler body 1, so that the air outlet hood 2 is protected when the air cooler body 1 is not working.
