Description

Technical Field

[0001] This utility model relates to the field of fresh air technology, specifically a plasma fresh air device. Background Technology

[0002] A plasma fresh air system is an air purification and ventilation device that uses plasma technology to purify the air entering a room. Plasma is the fourth state of matter, composed of positive ions and negative electrons, and is highly reactive, capable of decomposing and removing pollutants from the air.

[0003] In the existing technology, the HEPA filter of plasma fresh air equipment needs to be replaced after a certain period of use. Replacing the HEPA filter requires disassembling the unit, which takes a long time and is quite cumbersome, thus affecting work efficiency. Therefore, a plasma fresh air device is proposed to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a plasma fresh air device that offers advantages such as quick HEPA filter replacement without disassembling the unit. This solves the problem that in existing technologies, HEPA filters in plasma fresh air devices need to be replaced after a certain period of use, and replacing the HEPA filter requires disassembling the unit, which takes a long time and is cumbersome, thus affecting work efficiency.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A plasma fresh air device includes a shell, the left and right sides of which are respectively an air outlet and an air inlet. The shell has a purification chamber and a filter chamber that are respectively connected to the air outlet and the air inlet. The purification chamber and the filter chamber are connected. The right wall of the inner cavity of the purification chamber is provided with a fan module that is connected to the filter chamber. The left side of the fan module is provided with a plasma module that is connected to the fan module and is connected to the air outlet. The top of the shell has a rectangular stepped hole that is connected to the filter chamber. The front wall of the inner cavity of the filter chamber is provided with a lifting component that extends into the filter chamber and to the top of the shell. The rear side of the lifting component is fixedly connected with an assembly plate that is adapted to the filter chamber and extends into the rectangular stepped hole and is flush with the top of the shell. The right side of the assembly plate has an assembly hole. The inside of the assembly plate is provided with limiting components that are arranged in a ring array and extend into the assembly hole. The inside of the assembly hole is provided with HEPA filter elements that are adapted to both the assembly plate and the limiting components on the opposite side.

[0008] The beneficial effects of this utility model are:

[0009] This plasma fresh air device uses a rotating lifting assembly to raise the mounting plate through a rectangular stepped hole, which then brings out the HEPA filter. When the limiting assembly is subjected to external force, it can undergo elastic deformation, pushing the HEPA filter out of the mounting hole and pressing the new mounting hole into it. The opposite side of the limiting assembly is in contact with the outer ring of the HEPA filter. Reversing the lifting assembly will reset the mounting plate and the HEPA filter, thus completing the replacement of the HEPA filter. It has the advantage of being able to quickly replace the HEPA filter without disassembling the main unit.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the lifting assembly includes a screw thread and a linkage pipe. The screw thread extending to the top of the outer shell is rotatably connected to the front wall of the filter chamber. The outer side of the screw thread is threadedly connected to the linkage pipe extending into the filter chamber. An assembly plate is fixedly connected to the rear side of the linkage pipe.

[0012] The beneficial effect of adopting the above-mentioned further solution is that by rotating the bolt head screw with an electric wrench, the force generated by the rotation of the outer thread of the bolt head screw can drive the linkage pipe to move vertically, thereby raising the assembly plate through the rectangular stepped hole or lowering the assembly plate to reset it.

[0013] Furthermore, the wall of the rectangular stepped hole is fixedly connected with a rectangular rubber ring that is flush with the top of the outer shell and fits the top edge of the mounting plate.

[0014] The advantage of adopting the above-mentioned further solution is that the rectangular rubber ring is in close contact with the top outer side of the assembly plate, preventing air leakage from the gap.

[0015] Furthermore, the limiting component includes a limiting ball head block and a spring. The assembly plate is movably connected with limiting ball heads blocks arranged in a circular array and extending into the assembly hole. The rear side of each limiting ball head block is fitted with a spring located inside the assembly plate.

[0016] Furthermore, the outer side of the HEPA filter element is provided with annular grooves that are adapted to the opposite side of the limiting ball head block.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by removing the old HEPA filter element, pressing firmly against one side of the HEPA filter element, and then moving the limiting ball head block to the opposite side and retracting it into the assembly plate, the old HEPA filter element can be removed from the assembly hole. The new HEPA filter element is then aligned with the assembly hole and pressed in. After the limiting ball head block contacts the HEPA filter element, it retracts into the assembly plate, causing the spring to elastically deform. When the opposite side of the limiting ball head block aligns with the annular groove on the outside of the HEPA filter element, the spring returns to its elastic deformation, thereby pushing the limiting ball head block. The opposite ends of the limiting ball head block contact the bottom of the annular groove, limiting the HEPA filter element, thus completing the installation of the HEPA filter element.

[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] In the embodiments, by Figure 1-6This invention discloses a plasma fresh air device, comprising a housing 1, with an air outlet 2 and an air inlet 3 on its left and right sides, respectively. Inside the housing 1, a purification chamber 4 and a filter chamber 5 are respectively connected to the air outlet 2 and the air inlet 3. The purification chamber 4 and the filter chamber 5 are interconnected. A fan module 6, connected to the filter chamber 5, is located on the right wall of the inner cavity of the purification chamber 4. A plasma module 7, connected to and connected to the air outlet 2, is located on the left side of the fan module 6. A rectangular stepped hole 8, connected to the filter chamber 5, is located on the top of the housing 1. The inner wall of the filter chamber 5 is provided with a lifting assembly 9 that extends into the filter chamber 5 and to the top of the outer shell 1. The rear side of the lifting assembly 9 is fixedly connected to an assembly plate 10 that is adapted to the filter chamber 5 and extends into the rectangular stepped hole 8 and is flush with the top of the outer shell 1. An assembly hole 11 is provided on the right side of the assembly plate 10. The interior of the assembly plate 10 is provided with a limiting assembly 12 that is arranged in a ring array and extends into the assembly hole 11. The interior of the assembly hole 11 is provided with a HEPA filter element 13 that is adapted to both the assembly hole 13 and the limiting assembly 12 on the opposite side.

[0027] The lifting assembly 9 includes a screw rod 901 and a linkage pipe 902. The screw rod 901, which extends to the top of the outer shell 1, is rotatably connected to the inner wall of the front cavity of the filter chamber 5. The linkage pipe 902, which extends into the filter chamber 5, is threadedly connected to the outer side of the screw rod 901. An assembly plate 10 is fixedly connected to the rear side of the linkage pipe 902.

[0028] By turning the bolt head screw 901 with an electric wrench, the force generated by the rotation of the outer thread of the bolt head screw 901 can drive the linkage fitting 902 to move vertically, thereby raising the assembly plate 10 through the rectangular stepped hole 8 or lowering the assembly plate 10 to reset it.

[0029] A rectangular rubber ring 14 is fixedly connected to the wall of the rectangular stepped hole 8, which is flush with the top of the outer shell 1 and fits the top edge of the mounting plate 10.

[0030] The rectangular rubber ring 14 is in close contact with the top outer side of the mounting plate 10 to prevent air leakage at the gap.

[0031] The limiting component 12 includes a limiting ball head block 121 and a spring 122. The limiting ball head blocks 121 are movably connected inside the assembly plate 10 in a circular array and extend into the assembly hole 11. The rear side of each limiting ball head block 121 is fitted with a spring 122 located inside the assembly plate 10.

[0032] The outer side of the HEPA filter element 13 is provided with an annular groove 15 that is adapted to the opposite side of the limiting ball head block 121;

[0033] Remove the old HEPA filter 13, press firmly against one side of the HEPA filter 13, and then move the limiting ball head block 121 to the opposite side and retract it into the assembly plate 10. The old HEPA filter 13 can then be removed from the assembly hole 11. Align the new HEPA filter 13 with the assembly hole 11 and press it in. After the limiting ball head block 121 contacts the HEPA filter 13, it retracts into the assembly plate 10. At the same time, the spring 122 undergoes elastic deformation. When the opposite side of the limiting ball head block 121 aligns with the annular groove 15 on the outside of the HEPA filter 13, the spring 122 returns to its elastic deformation, thereby pushing the limiting ball head block 121. The opposite ends of the limiting ball head block 121 contact the bottom of the annular groove 15, thus limiting the HEPA filter 13 and completing the installation of the HEPA filter 13.

[0034] Working principle:

[0035] Step 1: Rotate the bolt head screw 901 with an electric wrench. The force generated by the rotation of the outer thread of the bolt head screw 901 can then drive the linkage fitting 902 to move vertically, thereby lifting the assembly plate 10 through the rectangular stepped hole 8 and taking out the HEPA filter element 13.

[0036] Step 2: Remove the old HEPA filter 13. Press down on one side of the HEPA filter 13 and then move the limiting ball block 121 to the opposite side and retract it into the assembly plate 10. The old HEPA filter 13 can then be removed from the assembly hole 11.

[0037] Step 3: Align the new HEPA filter element 13 with the mounting hole 11 and press it in. After the limiting ball head block 121 contacts the HEPA filter element 13, it retracts into the mounting plate 10. At the same time, the spring 122 undergoes elastic deformation. When the opposite side of the limiting ball head block 121 aligns with the annular groove 15 on the outside of the HEPA filter element 13, the spring 122 returns to its elastic deformation, thereby pushing the limiting ball head block 121. The opposite ends of the limiting ball head block 121 contact the bottom of the annular groove 15, thus limiting the HEPA filter element 13 and completing the installation of the HEPA filter element 13. Finally, reverse the screw 901 to reset the mounting plate 10, and the top outer side of the mounting plate 10 is in close contact with the rectangular rubber ring 14, completing the replacement of the HEPA filter element 13.
