Through air exchange, it can effectively reduce the indoor temperature and at the same time provide a fresh air environment. It is suitable for various places such as factories, warehouses, offices, etc.

[0003] Currently, a front panel body 1 is rotatably installed on the chassis of the air cooler. A plurality of through holes are provided on the front panel body, and the air cooler intakes air through the through holes of the front panel body. A filter screen is installed on the front panel body, and the filter screen is detachably and fixedly installed on the front panel body by a plurality of bolts. The filter screen filters the intake air of the air cooler, so that impurities are not easily introduced into the air cooler.

[0004] After the air cooler is used for a long time, it is necessary to disassemble and replace the filter screen. Using the method of turning bolts to replace the filter screen has the problem that it is inconvenient to disassemble and install the filter screen. Summary of the Utility Model

[0005] In order to facilitate the disassembly and assembly of the filter screen, the present application provides a filter screen structure for the front panel of an air cooler.

[0006] A filter screen structure for the front panel of an air cooler provided by the present application adopts the following technical solutions:

[0007] A filter screen structure for the front panel of an air cooler includes a front panel body and a filter screen. The front panel body is a metal plate, the filter screen is a flexible net, a magnetic attraction strip is arranged on the outer peripheral side of the filter screen, the magnetic attraction strip adsorbs on the front panel body, a limiting plate is arranged on the side wall of the front panel close to the filter screen, there are two limiting plates, and the two limiting plates are located on the upper and lower sides of the filter screen and limit the filter screen.

[0008] By adopting the above technical solutions, when installing the filter screen, first bend the filter screen, put the upper and lower ends of the filter screen into the two limiting plates, and then adsorb and fix the filter screen on the front panel body through the magnetic attraction strip, and the installation of the filter screen can be quickly completed. When disassembling the filter screen, first bend the filter screen and move one side of the filter screen out of the limiting plate, and the disassembly of the filter screen can be quickly completed, making the disassembly and assembly of the filter screen more convenient and fast.

[0009] Preferably, the limiting plate includes a first plate body and a second plate body. The two first plate bodies are fixedly arranged at the upper and lower ends of the side wall of the front panel body close to the filter screen. The first plate body is perpendicular to the front panel body. The upper and lower sides of the filter screen abut against the mutually close side walls of the two first plate bodies. The two second plate bodies are fixedly installed on one side of the two first plate bodies close to each other along the direction perpendicular to the first plate body.

[0010] By adopting the above technical solution, when the filter screen is adsorbed on the front plate body by the magnetic adsorption strip, the two first plate bodies abut and limit the filter screen, so that the position of the filter screen is not easy to move, and the two second plate bodies limit the filter screen, so that when the air intake of the cold air blower is large, the filter screen will not be blown up and separated from the front plate body.

[0011] Preferably, a receiving groove is formed on the side wall of the front plate body close to the filter screen, a lifting plate is rotatably arranged in the receiving groove of the front plate body, the filter screen covers the hinged end of the lifting plate, and the moving end of the lifting plate is located outside the filter screen.

[0012] By adopting the above technical solution, when the filter screen needs to be disassembled, the lifting plate is rotated by the moving end of the lifting plate. When the lifting plate rotates, it will drive the filter screen to lift, causing the filter screen to deform, so as to facilitate the quick disassembly of the filter screen. When the filter screen needs to be installed, the lifting plate is rotated and installed in the receiving groove, so that the lifting plate will not affect the installation of the filter screen.

[0013] Preferably, a pull ring is arranged on the moving end of the lifting plate.

[0014] By adopting the above technical solution, using the pull ring is convenient for pulling up the lifting plate from the receiving groove.

[0016] By adopting the above technical solution, when installing the filter screen, first rotate the third plate body away from the front plate body, and the filter screen can be installed without bending the filter screen. After the filter screen is installed, first rotate the third plate body to limit the filter screen, and then use the locking member to lock the third plate body, so that the installation of the filter screen is more convenient and fast.

[0017] Preferably, the locking member includes an eccentric wheel, the eccentric wheel is fixedly arranged on the rotating shaft, and when the third plate body rotates to limit the filter screen, the eccentric side of the eccentric wheel abuts against the front plate body and limits the third plate body.

[0018] By adopting the above technical solution, the third plate body drives the eccentric wheel to rotate synchronously when rotating. When the third plate body rotates to limit the filter screen, the eccentric side of the eccentric wheel abuts against the front plate body and limits the third plate body. When the third plate body rotates away from the front plate body, the eccentric side of the eccentric wheel is separated from the front plate body, and the limit of the front plate body can be released.

[0019] Preferably, a handle is fixedly arranged on the eccentric wheel.

[0020] By adopting the above technical solution, using the handle is convenient for rotating the eccentric wheel and the third plate body.

[0021] Preferably, a friction block is fixedly arranged on the front plate body, and the eccentric side of the eccentric wheel abuts against the friction block.

[0022] By adopting the above technical solution, when the eccentric wheel limits the third plate body, the eccentric side of the eccentric wheel abuts against the friction block, thereby increasing the static friction force on the outer side wall of the eccentric wheel and making the limiting effect of the eccentric wheel better.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By using the magnetic attraction strip, when installing the filter screen, first bend the filter screen, put the upper and lower ends of the filter screen into the two limiting plates, and then adsorb and fix the filter screen on the front plate body through the magnetic attraction strip, so that the installation of the filter screen can be quickly completed. When disassembling the filter screen, first bend the filter screen and move one side of the filter screen out of the limiting plate, so that the disassembly of the filter screen can be quickly completed, making the disassembly and installation of the filter screen more convenient and fast;

[0025] 2. Through the first plate body and the second plate body, when using the magnetic attraction strip to adsorb the filter screen on the front plate body, the two first plate bodies abut against and limit the filter screen, making the position of the filter screen not easy to move, and the two second plate bodies limit the filter screen, so that when the air intake of the cold air blower is large, the filter screen will not be blown up and separated from the front plate body;

[0026] 3. With the help of the lifting plate, when the filter screen needs to be disassembled, rotate the lifting plate through the moving end of the lifting plate. When the lifting plate rotates, it will drive the filter screen to lift, causing the filter screen to deform, so as to facilitate the quick disassembly of the filter screen. When the filter screen needs to be installed, rotate the lifting plate and install it in the receiving groove, so that the lifting plate will not affect the installation of the filter screen.

Detailed implementation manners

[0035] The following further elaborates on the present application in conjunction with the attached Figures 1-7 drawings.

[0036] Embodiment 1:

[0037] The embodiment of the present application discloses a filter screen structure of the front panel of a cold air blower.

[0038] Referring to Figure 1 , Figure 2 and Figure 3 , a filter screen structure of the front panel of a cold air blower includes a front panel body 1 and a filter screen 2. The front panel body 1 is hingedly installed on the box body, the filter screen 2 is installed on the side wall of the front panel body 1 close to the inside of the box body, and a magnetic attraction strip 3 is fixedly installed on the outer peripheral side wall of the filter screen 2. In the present application, the front panel body 1 can be made of a metal or alloy material that can be adsorbed by a magnet, and the filter screen 2 can be made of a flexible net.

[0039] Limiting plates 4 are fixedly installed on both the upper and lower sides of the side wall of the front panel body 1 close to the filter screen 2. The limiting plate 4 includes a first plate body 41 and a second plate body 42. The first plate body 41 is installed on the limiting plate 4 and is perpendicular to the limiting plate 4, and the two first plate bodies 41 are parallel to each other. The two second plate bodies 42 are fixedly installed at one ends of the two first plate bodies 41 away from the limiting plate 4, and the two second plate bodies 42 are located on the side where the two first plate bodies 41 are close to each other.

[0040] When installing the filter screen 2, first bend the filter screen 2 from the middle of the filter screen 2, put the upper and lower sides of the filter screen 2 into two limiting plates 4, and then adsorb and fix the filter screen 2 on the front plate body 1 through the magnetic strip 3, so that the filter screen 2 can be quickly installed. At this time, the upper and lower sides of the filter screen 2 abut against the side walls of the two first plate bodies 41 close to each other, and the two first plate bodies 41 limit the filter screen 2 in the vertical direction, so that the installation position of the filter screen 2 is not easily offset. During the air intake process of the cold air blower, the two second plate bodies 42 limit the filter screen 2, so that when the air intake volume of the cold air blower is large, the filter screen 2 will not be blown off the front plate body 1. When disassembling the filter screen 2, first bend the filter screen 2 from the middle of the filter screen 2, move one side of the filter screen 2 out of the limiting plate 4, and the filter screen 2 can be disassembled from the front plate body 1, so that the filter screen 2 can be quickly disassembled and assembled.

[0041] The implementation principle of the front plate filter screen structure of the cold air blower in the embodiment of the present application is: the magnetic strip 3 is used to adsorb and fix the filter screen 2 on the front plate body 1, so that the installation and insertion of the filter screen 2 are more convenient and fast.

[0042] Embodiment 2:

[0043] Refer to Figure 4 and Figure 5 In this embodiment, the difference from Embodiment 1 is that two receiving grooves 5 are horizontally opened in the middle of the side wall of the front plate body 1 close to the filter screen 2, and a lifting plate 6 is rotatably installed in each of the two receiving grooves 5 of the front plate body 1. The ends of the two lifting plates 6 close to each other are hinged ends, and the filter screen 2 covers the upper part of the hinged ends of the two lifting plates 6.

[0044] The side of the lifting plate 6 away from its hinged end is a moving end, and a pull ring 7 is fixedly installed on the moving end of each of the two lifting plates 6. The lifting plate 6 can be pulled up through the pull ring 7. When the lifting plate 6 does not rotate, the lifting plate 6 is adaptively located in the receiving groove 5 and is flush with the side wall of the front plate body 1, so that the lifting plate 6 does not affect the adsorption and fixation of the filter screen 2.

[0045] When the filter screen 2 needs to be disassembled, the two lifting plates 6 are rotated by pulling the two pull rings 7, and the two lifting plates 6 lift the filter screen 2 from both sides of the middle of the filter screen 2, so that the magnetic strip 3 is separated from the front plate body 1. At this time, the middle of the filter screen 2 bulges, so that the filter screen 2 can be directly removed from the front plate body 1 at the bulging part in the middle of the filter screen 2, making the disassembly of the filter screen 2 more convenient and fast.

[0046] The implementation principle of Embodiment 2 of the present application is: when the filter screen 2 needs to be disassembled, the lifting plate 6 is rotated by driving the pull ring 7. When the lifting plate 6 rotates, it will drive the filter screen 2 to lift, causing the filter screen 2 to deform, so as to facilitate the quick disassembly of the filter screen 2.

[0047] Embodiment 3:

[0048] Refer to Figure 6 andFigure 7 , the difference between this embodiment and Embodiment 1 is that the limiting plate 4 located at the top of the front plate body 1 includes a third plate body 43. Two mounting blocks 12 are fixedly installed at the top of the side wall of the front plate body 1 close to the filter screen 2. A rotating shaft 8 is rotatably installed in the two mounting blocks 12. The third plate body 43 is located between the two mounting blocks 12 and is fixedly sleeved on the rotating shaft 8.

[0049] Locking members are installed at both ends of the rotating shaft 8. The locking members include eccentric wheels 9. The two eccentric wheels 9 are fixedly sleeved at both ends of the bearing and are located on the sides of the two mounting blocks 12 away from each other. A grip 10 is fixedly installed on each eccentric wheel 9, and the grip 10 is parallel to the third plate body 43. Friction blocks 11 are fixedly installed at the top of the side wall of the front plate body 1 at the positions of the two eccentric wheels 9. When the eccentric side of the eccentric wheel 9 abuts against the friction block 11, the friction block 11 locks the third plate body 43 through the eccentric wheel 9 and the rotating shaft 8.

[0050] When installing the filter screen 2, first drive the eccentric wheel 9 to rotate through the grip 10 to release the lock of the third plate body 43. Press the bottom end of the filter screen 2 against the first plate body 41 at the bottom of the front plate body 1, adsorb and fix the filter screen 2 on the front plate body 1, and then drive the eccentric wheel 9 to rotate through the grip 10 to lock the third plate body 43. At this time, the third plate body 43 presses and fixes the top of the filter screen 2. In this way, on the one hand, it is not necessary to bend the filter screen 2 when installing the filter screen 2, making the installation of the filter screen 2 more convenient. On the other hand, the filter screen 2 is pressed and fixed, making the installation of the filter screen 2 more stable. Similarly, by driving the eccentric wheel 9 to rotate through the grip 10 to release the lock of the third plate body 43, the filter screen 2 can be quickly removed without bending the filter screen 2.

[0051] The implementation principle of Embodiment 3 of this application is: by rotating the grip 10 to drive the third plate body 43 to rotate, the installation and disassembly of the filter screen 2 do not require bending the filter screen 2, so that the disassembly and assembly of the filter screen 2 are more convenient and fast.

[0052] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
