Description

Technical Field

[0001] The utility model relates to the technical field of dust covers, and more specifically, to a dust cover for a cold air blower. Background Art

[0002] Cold air blowers are divided into industrial cold air blowers for refrigeration and household cold air blowers. Industrial cold air blowers are generally used in refrigeration environments such as cold storages and cold chain logistics. Household cold air blowers, also known as water-cooled air conditioners, are evaporative cooling and ventilation units that integrate functions of cooling, ventilation, dust prevention, and odor removal. It uses water as a medium to fully wet the "wet curtain" (a corrugated fiber laminate with high evaporation efficiency and high anti-corrosion performance formed by multiple processes). When dry and hot air passes through the wet curtain, water absorbs a large amount of heat in the air, and the flowing out air is moist and cool. When installing a cold air blower, a dust cover needs to be installed at the input end of the cold air blower to prevent dust and other debris from entering the cold air blower and causing damage to the cold air blower. For this reason, a dust cover for a cold air blower is proposed.

[0003] For existing dust covers of cold air blowers, most of them use bolts to fix the dust cover at the input end of the cold air blower. Therefore, tools are required to disassemble the bolts for both installation and disassembly, which is rather troublesome. Moreover, for existing dust covers of cold air blowers, dust will accumulate after long-term operation, so the dust cover needs to be frequently disassembled for cleaning, which is also rather troublesome.

[0029] Such as Figure 1 、 2As shown in Figures 2 and 3, the utility model provides a dust-proof cover for a cold air blower, which includes a dust-proof cover body 1. A cold air blower housing 4 is movably arranged on one side of the dust-proof cover body 1, a dust filter plate 6 is movably arranged inside the dust-proof cover body 1, and a louver 5 is movably arranged inside the dust-proof cover body 1.

[0030] In order to avoid the problem of troublesome disassembly of the dust-proof cover body 1 and make it more convenient to replace and clean the dust filter plate 6, a filter plate installation device 2 for installing the dust filter plate 6 inside the dust-proof cover body 1 is provided inside the dust filter plate 6, which is used to insert the dust filter plate 6 into the inside of the dust-proof cover body 1 and limit and fix the dust filter plate 6.

[0031] As Figure 4 shown, the filter plate installation device 2 includes an installation groove 21 opened inside the dust-proof cover body 1. The dust filter plate 6 is inserted into the inside of the installation groove 21. Notches 22 are respectively opened at the upper and lower ends on one side of the dust-proof cover body 1. Anti-slip grooves 23 are opened at the upper and lower ends of the dust filter plate 6. Elastic chambers 24 are respectively opened inside the upper and lower ends of the dust filter plate 6. A first spring 25 and a movable end 26 are movably arranged inside the elastic chamber 24. The first spring 25 is located below the movable end 26. Limit grooves 27 are respectively opened at the upper and lower ends of the dust-proof cover body 1. The movable end 26 is adapted to the limit groove 27. By inserting the dust filter plate 6 into the installation groove 21 and then sliding the movable end 26 into the limit groove 27, the installation and fixation of the dust filter plate 6 can be realized. When it is necessary to clean the dust, the two movable ends 26 are pressed into the elastic chamber 24, and the anti-slip groove 23 is held by hand through the notch 22, and the dust filter plate 6 can be pulled out of the installation groove 21, thus avoiding the problem of troublesome disassembly of the dust-proof cover body 1 and making it more convenient to replace and clean the dust filter plate 6.

[0032] Furthermore, in order to reduce the use of bolts and tools, installation and fixation devices 3 for limiting the dust-proof cover body 1 are respectively arranged on both sides of the cold air blower housing 4, which are used to limit and fix the dust-proof cover body 1.

[0033] As Figure 5 and 6As shown in the figure, the installation and fixing device 3 includes two fixing plates 31. The two fixing plates 31 are fixedly arranged on one side of the cold air blower housing 4. A partition plate 33 is fixedly arranged between the two fixing plates 31. A rotating shaft 34 penetrates through the inner sides of the two fixing plates 31. A stop plate 36 and a pressing plate 37 are fixedly arranged on the outer surface of the rotating shaft 34. The pressing plate 37 is located on one side of the partition plate 33. A second spring 35 is fixedly arranged between the pressing plate 37 and the partition plate 33. An inclined tooth groove plate 32 is fixedly arranged on one side of the dust-proof cover body 1. The inclined tooth groove plate 32 is inserted into the inner sides of the two fixing plates 31. The inclined tooth groove plate 32 is located on one side of the partition plate 33. The stop plate 36 is movably connected to the rotating shaft 34. A sealing groove 38 is formed on one side of the cold air blower housing 4. A sealing strip 39 is fixedly arranged on one side of the dust-proof cover body 1. The sealing groove 38 is adapted to the sealing strip 39. By inserting the inclined tooth groove plate 32 between the two fixing plates 31 and using the second spring 35 to bounce the pressing plate 37, the stop plate 36 is clamped on one side of the inclined tooth groove plate 32. Therefore, the effect of fixing the dust-proof cover body 1 can be achieved. By the close cooperation of the sealing groove 38 and the sealing strip 39, it is avoided that the dust-proof cover body 1 makes noise due to the vibration of the cooler, and the sealing performance of the dust-proof cover body 1 is improved. When disassembly is required, press the pressing plate 37 to move the stop plate 36 away from the inclined tooth groove plate 32, and then pull out the dust-proof cover body 1 and the inclined tooth groove plate 32, so that the disassembly of the dust-proof cover body 1 can be realized, reducing the use of bolts and tools and making the disassembly and installation more convenient.

[0034] The working principle is as follows: When the present utility model is in use, the installation and fixing device 3 can be used to install the present utility model on one side of the cold air blower housing 4. When dust accumulates due to the long-term operation of the cold air blower, the dust filter plate 6 can be pulled out and cleaned through the filter plate installation device 2. Overall, the trouble of bolt fixing is reduced, making the installation and disassembly of the dust-proof cover body 1 more convenient, reducing the trouble of frequently disassembling the dust-proof cover body 1. When dust accumulates, it can be cleaned and replaced by pulling out the dust filter plate 6, improving the practicability of the present utility model and reducing redundant and complex operations.

[0035] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
