Description

Technical Field

[0001] The utility model relates to a high-efficiency air supply outlet and a clean room comprising the high-efficiency air supply outlet. Background Art

[0002] High-efficiency air supply outlet (HEPA BOX) is a terminal filtration device used for the renovation and construction of clean rooms of levels 1000-300000. As the last filter of the clean room air supply, it plays a key role in whether the cleanliness of the clean room is qualified.

[0003] Most of the high-efficiency air supply vents in the prior art only contain one filter, and the air supply must be turned off when replacing it.

[0004] Furthermore, because the damper of the high-efficiency air supply vent is located above the room's ceiling, adjustment is inconvenient. For example, the Chinese utility model patent, Publication No. CN 206929944 U, entitled "Variable Air Volume Air Supply Vent for Purified Operating Rooms," has a complex adjustment mechanism with multiple components. Another example, the Chinese utility model patent, Publication No. CN 220038722 U, entitled "Intelligent High-Efficiency Air Supply Vent with Embedded Constant Air Volume Valve Structure," uses electronic control via a control system, requiring additional wiring and costs.

[0005] Therefore, the high-efficiency air supply vents in the prior art cannot realize filter replacement when the air supply is turned on, and the adjustment structure of the air valve is complex or costly. Summary of the Invention

[0006] In view of this, in order to overcome the defects in the prior art, the purpose of the present invention is to provide an improved high-efficiency air supply outlet, which can realize the replacement of the filter while maintaining the air supply and facilitate the adjustment of the air inlet valve.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A high-efficiency air supply vent includes a diffuser, a housing, a top cover, and an air inlet. The air inlet is provided with an air inlet valve. The housing includes at least one high-efficiency filter and one sub-high-efficiency filter, with the sub-high-efficiency filter positioned between the air inlet and the high-efficiency filter. The high-efficiency air supply vent includes an adjustment mechanism for controlling the opening or closing of the air inlet valve, or the degree of opening thereof. The adjustment mechanism includes an actuator disposed on the air inlet, a regulator disposed on the diffuser, and a flexible shaft disposed between the regulator and the actuator. The actuator is connected to the air inlet valve. The regulator can be a bolt, screw, or pin, capable of rotating along its own axis, thereby driving the flexible shaft to rotate.

[0009] According to some preferred implementation aspects of the present invention, the actuator assembly includes an input shaft, an output shaft and a gear assembly located between the input shaft and the output shaft, one end of the flexible shaft is connected to the regulator, and the other end of the flexible shaft is connected to the input shaft.

[0010] Preferably, the input shaft extends in a vertical direction and the output shaft extends in a horizontal direction, that is, the input shaft and the output shaft are perpendicular to each other, and the gear assembly can be a mutually meshing bevel gear assembly to achieve direction adjustment.

[0011] According to some preferred embodiments of the present invention, the input shaft extends vertically downward from the actuator, and the regulator extends vertically upward from the diffuser. Both the input shaft and the regulator are vertically oriented for easy adjustment.

[0012] According to some preferred implementation aspects of the present invention, the air inlet valve includes a rotating shaft and a blade arranged on the rotating shaft, and the output shaft of the actuator is connected to the rotating shaft for rotating the rotating shaft.

[0013] During adjustment, the regulator is rotated to drive the flexible shaft to rotate, which in turn drives the rotating shaft to rotate through the input shaft, gear assembly, and output shaft to adjust the blade angle and control the opening or closing degree of the air inlet valve.

[0014] According to some preferred embodiments of the present invention, the housing includes an outer box, an inner box, and an insulation layer located between the outer box and the inner box. The provision of the insulation housing can effectively prevent condensation at ordinary air outlets.

[0016] According to some preferred implementation aspects of the present invention, the top cover is detachably connected to the top of the shell, and snap-fit buckles are provided between opposite sides of the top cover and the top of the shell.

[0017] The top cover is designed to be openable, allowing personnel to replace the sub-HEPA filter without entering the cleanroom, reducing contamination to the cleanroom. The top sub-HEPA filter can also be replaced without shutting off the air supply. Furthermore, since the HEPA filter is protected by a sub-HEPA filter at the front, the service life of the HEPA filter can be effectively extended.

[0018] According to some preferred implementation aspects of the present invention, the air inlet is arranged on the side of the shell, and the air inlet direction is parallel to the plane where the high efficiency filter or sub-high efficiency filter is located.

[0019] According to some preferred embodiments of the present invention, the high-efficiency air supply vent includes a generator disposed within the housing and corresponding to the air inlet. The generator can generate electricity using the supplied air and power sensors within the high-efficiency air supply vent, such as a wind speed sensor, a temperature and humidity sensor, or a pressure differential sensor.

[0020] The utility model also provides a clean room comprising the high-efficiency air supply outlet as described above.

[0021] Due to the implementation of the above technical solutions, the present invention has the following advantages compared with the prior art: the high-efficiency air supply outlet of the present invention, on the one hand, is provided with a high-efficiency filter and a sub-high-efficiency filter, and the top cover is rotatably or detachably connected to the shell, so that the sub-high-efficiency filter can be replaced while the air is continuously supplied; on the other hand, the actuator and the regulator are connected by a flexible shaft, so that the air inlet valve can be adjusted indoors.

DETAILED DESCRIPTION

[0030] In order to help those skilled in the art better understand the technical solutions of the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0031] like Figure 1-7 As shown, the clean room of this embodiment has a high-efficiency air supply vent 1 installed on its ceiling. The high-efficiency air supply vent 1 includes a diffuser 2, a shell 3, a top cover 4, an air inlet 5, a generator 6, and an adjustment mechanism for controlling the opening or closing of the air inlet valve 7. The top cover 4, shell 3, and diffuser 2 are arranged in sequence to form a space for accommodating the generator 6 and the filter. The shell 3 includes an outer box 121, an inner box 122, and an insulation layer 123 located between the outer box 121 and the inner box 122. The outer box 121 is a color-coated steel plate, and the inner box 122 is a stainless steel plate. The provision of the insulation shell 3 can effectively prevent condensation that occurs in ordinary air supply vents. The generator 6 can generate electricity using the supplied air and power sensors within the high-efficiency air supply vent, such as a wind speed sensor, a temperature and humidity sensor, or a pressure differential sensor.

[0032] The high-efficiency air supply outlet 1 in this embodiment is provided with a misting pipe 15 at the front end of the generator 6 , which can be used to test the high-efficiency air supply outlet 1 .

[0033] The top cover 4 in this embodiment is an openable structure, so that personnel can replace the filter without entering the clean room, reducing the contamination of the clean room by personnel. At the same time, the top sub-high efficiency filter 9 can be replaced without turning off the air supply. Specifically, the top cover 4 is rotatably connected to the top of the shell 3; one side of the top cover 4 is rotatably connected to the top of the shell 3 through a rotating member 14, and a snap-fit buckle 13 is provided between the other opposite side of the top cover 4 and the top of the shell 3; or, the top cover 4 is detachably connected to the top of the shell 3, and a snap-fit buckle 13 is provided between the two opposite sides of the top cover 4 and the top of the shell 3. In this embodiment, the former method, i.e., the rotatable connection, is preferred.

[0034] Generator 6 is disposed within housing 3 and corresponding to air inlet 5, which is equipped with an air inlet valve 7. Air inlet 5 is located on the side of housing 3, with the air inlet direction parallel to the plane where HEPA filter 8 or sub-HEPA filter 9 is located. Air inlet valve 7 includes a rotating shaft 71 and a blade 72 disposed on rotating shaft 71. The output shaft of actuator 10 is connected to rotating shaft 71 for rotating shaft 71.

[0035] At least one high efficiency filter 8 (H14, filtration efficiency ≧0.3um≧99.995%) and a sub-high efficiency filter 9 (H10, filtration efficiency ≧0.5um≧95%) are provided in the housing 3. The sub-high efficiency filter 9 is provided between the air inlet 5 and the high efficiency filter 8. The front end of the high efficiency filter 8 is protected by the sub-high efficiency filter 9, which can effectively extend the service life of the high efficiency filter 8.

[0036] A support member 16 connected to the inner box 122 is provided between the HEPA filter 8 and the sub-HEPA filter 9. The HEPA filter 8 and the sub-HEPA filter 9 are fixed to the support member 16 by a pressing block 18 and a fastener 17 such as a screw.

[0037] The adjustment mechanism includes an actuator 10 mounted on the air inlet 5, a regulator 11 mounted on the diffuser plate 2, and a flexible shaft (not shown) disposed between the regulator 11 and the actuator 10. The regulator 11 can be a bolt, screw, or pin, capable of rotating along its own axis, thereby driving the flexible shaft. The regulator 11 on the diffuser plate 2 allows adjustment of the air inlet valve 7 within the room.

[0038] Specifically, the actuator assembly 10 includes an input shaft 101, an output shaft, and a gear assembly positioned between the input and output shafts. One end of the flexible shaft is connected to the regulator 11, and the other end is connected to the input shaft 101. The input shaft 101 extends vertically, while the output shaft extends horizontally, meaning the two shafts are perpendicular to each other. The gear assembly can be a meshing bevel gear assembly to facilitate directional adjustment. The input shaft 101 extends vertically downward from the actuator 10, while the regulator 11 extends vertically upward from the diffuser plate 2. Therefore, both the input shaft 101 and the regulator 11 are oriented vertically, facilitating adjustment.

[0039] During adjustment, the regulator 11 is rotated to drive the flexible shaft to rotate, and the input shaft 101, the gear assembly, and the output shaft are then used to drive the rotating shaft 71 to rotate, thereby adjusting the angle of the blade 72 and controlling the opening or closing degree of the air inlet valve 7.

[0040] This utility model features a high-efficiency air outlet with a side-mounted, pivoting connection at the top, creating an openable structure. The interior features a double-layer filter structure, with a sub-HEPA filter at the top and a HEPA filter at the bottom. This eliminates the need for personnel to replace filters in the cleanroom, reducing contamination. Furthermore, the top sub-HEPA filter can be replaced without shutting down the air supply. Because the HEPA filter is protected by a sub-HEPA filter at the front, its service life is significantly extended, typically lasting 6-8 years. A flexible shaft connects the actuator and regulator, enabling indoor adjustment of the air inlet valve.

[0041] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of protection of the present invention.
