Description

Technical Field

[0001] This utility model belongs to the field of ventilation system technology, specifically a detachable and maintainable variable air volume ventilation system filter device structure. Background Technology

[0002] Ventilation systems achieve indoor air circulation and replacement by introducing fresh outdoor air and expelling stale indoor air. Their main components include fans, ducts, air outlets, and various air handling equipment. Ventilation equipment is generally equipped with a filtration structure to intercept dust in the air.

[0003] Meanwhile, a data center purification and ventilation device with application number CN202021163125.3 includes a ventilation duct with a ventilation filter structure inside. The ventilation filter structure includes: a first motor, a first pulley, two mounting brackets, a rotating shaft, a second pulley, a belt, a fan, a mounting groove, a filter screen, and an opening assembly. The first motor is fixedly installed on the lower wall of the ventilation duct, the first pulley is fixedly installed on the drive end of the first motor, the upper ends of the two mounting brackets are fixedly installed on the upper wall inside the ventilation duct, the rotating shaft is movably fitted into the lower ends of the two mounting brackets through rolling bearings, the second pulley is fitted onto the rotating shaft, and an opening is provided on the lower wall of the ventilation duct.

[0004] However, the following problems were found in the implementation of the relevant technology: the filter screen used for filtration is embedded in the installation groove, but no positioning structure is set. As a result, simply embedding the filter screen into the installation groove from top to bottom does not improve the stability of the filter screen installation and it is easy for it to fall off. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a detachable and maintainable variable air volume ventilation system filter device structure, which has the advantage of quickly connecting and installing the filter screen with the ventilation structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detachable and maintainable variable air volume ventilation system filter device structure, including a ventilation frame, a connecting frame connected to the surface of the ventilation frame, two locking plates engaged on the inner side of the connecting frame, filter blades connected between the two locking plates, a ventilation fan connected to the inner side of the ventilation frame, a protective frame connected to the surface of the ventilation frame, and a locking component provided on the connecting frame.

[0007] Preferably, the engaging assembly includes four support rods, four first magnetic absorbing plates, four second magnetic absorbing plates, and four composite expansion springs. Each pair of support rods is disposed on the inner side of each locking plate. Two sliding plates are slidably connected to the surface of each pair of support rods. A limit rod is connected to one side of each of the four sliding plates. The four first magnetic absorbing plates are disposed at one end of each of the four limit rods. The four second magnetic absorbing plates are disposed on the inner side of the connecting frame. The four composite expansion springs are respectively sleeved on the outer side of each of the four support rods.

[0008] Preferably, the surfaces of each pair of skateboards are respectively attached to the inner side of each of the card plates.

[0009] Preferably, all four limiting rods are engaged with the inner side of the connecting frame.

[0010] Preferably, the four first magnetic absorbing sheets are magnetically attracted to the four second magnetic absorbing sheets respectively.

[0011] Preferably, the two ends of each pair of composite expansion springs are respectively connected to the surface of each pair of sliding plates.

[0012] Preferably, the two card plates are symmetrically arranged on the left and right sides of the vertical center line of the connecting frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes the outward expansion effect of a composite expansion spring to ensure that the upper and lower sliding plates are always supported by opposing forces. This facilitates the two sliding plates to approach each other under external force while also allowing them to reset and separate. Furthermore, it allows the limiting rod to be fixed to the inside of the connecting frame under the magnetic attraction of the first and second magnetic plates. This facilitates the snap-fit ​​installation of the card plate and filter fan to the connecting frame, preventing the filter fan from falling off. It also allows for easy separation and disassembly of the card plate and filter fan from the connecting frame, facilitating maintenance and improving the usability of the filter fan.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] like Figures 1 to 7 As shown, this utility model provides a detachable and maintainable variable air volume ventilation system filter device structure, including a ventilation frame 1, a connecting frame 3 connected to the surface of the ventilation frame 1, two clamping plates 6 snapped together on the inner side of the connecting frame 3, and a filter fan 7 connected between the two clamping plates 6 to facilitate filtration. A ventilation fan 4 is connected to the inner side of the ventilation frame 1, a protective frame 5 is connected to the surface of the ventilation frame 1, and a snap-fit ​​component 2 is provided on the connecting frame 3.

[0027] Specifically, the engaging assembly 2 includes four support rods 21, four first magnetic absorbing pieces 24, four second magnetic absorbing pieces 25, and four composite expansion springs 26. Each pair of support rods 21 is respectively disposed on the inner side of each locking plate 6. Two sliding plates 22 are slidably connected to the surface of each pair of support rods 21. Each of the four sliding plates 22 is connected to a limiting rod 23 on one side to facilitate engaging and positioning with the inside of the connecting frame 3. The four first magnetic absorbing pieces 24 are respectively disposed at one end of the four limiting rods 23. The four second magnetic absorbing pieces 25 are all disposed on the inner side of the connecting frame 3 to facilitate subsequent magnetic connection. The four composite expansion springs 26 are respectively sleeved on the outer side of the four support rods 21.

[0028] Furthermore, the surfaces of each pair of skateboards 22 are respectively attached to the inner side of each card plate 6, which helps to improve the stability of the skateboards 22 during translation and movement and avoids wobbling.

[0029] Furthermore, all four limiting rods 23 are engaged with the inner side of the connecting frame 3, which helps to limit the movement.

[0030] It is worth noting that the four first magnetic pieces 24 are magnetically attracted to the four second magnetic pieces 25 respectively, which facilitates the improvement of the stability of the limiting rod 23 when it is engaged inside the connecting frame 3.

[0031] It is worth noting that the two ends of each pair of composite expansion springs 26 are connected to the surfaces of each pair of slide plates 22 respectively, and the outward expansion makes it easy for the corresponding slide plates 22 to have opposing driving forces.

[0032] It is worth mentioning that the two clamping plates 6 are symmetrically arranged on the left and right sides of the vertical center line of the connecting frame 3, which facilitates the installation of the filter fan 7 with the connecting frame 3 and makes it easy to disassemble.

[0033] The first magnetic attracting plate 24, the second magnetic attracting plate 25, and the filter fan plate 7 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, back, left, and right" views of this device are... Figure 1 The direction shown in the diagram is the reference.

[0034] Working principle: First, align the position of the connecting frame 3 with the ventilation frame 1. Then, insert the two locking plates 6 into the connecting frame 3. At this time, press down the two upper sliding plates 22 and simultaneously lift the two lower sliding plates 22, causing the two upper limiting rods 23 and the first magnetic suction plate 24 to move down and the two upper limiting rods 23 and the first magnetic suction plate 24 to move up. This allows the two locking plates 6 to smoothly enter the connecting frame 3. After that, release the four sliding plates 22. Then, under the expansion action of the four composite expansion springs 26, the two upper limiting rods 23 and the first magnetic suction plate 24 will be released. Rod 23 and the first magnetic absorbing piece 24 are pushed upwards, and similarly, the two limiting rods 23 and the first magnetic absorbing piece 24 below are pressed down, so that the four first magnetic absorbing pieces 24 and the corresponding four second magnetic absorbing pieces 25 are magnetically attracted to each other, thus completing the positioning and installation of the two clamping plates 6 and the filter fan 7. Similarly, when removing the filter fan 7, simply follow the same operation to move the first magnetic absorbing piece 24 in opposite directions to separate it from the second magnetic absorbing piece 25. This facilitates both quick installation and quick removal of the clamping plates 6 and the filter fan 7, thereby improving the convenience of installation and making it easy to remove and maintain the filter fan 7.
