Description

Technical Field

[0001] This utility model relates to an air supply device, specifically a fully sealed high-efficiency air supply device. Background Technology

[0002] An air supply device is an air supply device used in cleanrooms. It is mainly used to filter and deliver fresh air to ensure that the air quality in the cleanroom meets high standards. It is widely used in many fields, including medical, biomedical, precision manufacturing, food processing and electronic cleanrooms.

[0003] Existing air supply devices have complex structures and unreasonable designs. The filter structure inside the device cannot form a seal with the entire cavity of the device, causing some gas to bypass the filter and leak out directly during transportation, resulting in incomplete gas filtration. In addition, existing air supply devices lack a finely designed flow guiding structure, causing the gas to be transported in a scattered and irregular manner, thus reducing air supply efficiency. To address these issues, the inventors have improved the structure of the air supply device. Utility Model Content

[0004] The purpose of this invention is to provide a fully sealed, high-efficiency air supply device. This device has a simple structure and reasonable design. There is no gap between the filter and the inner wall of the air supply outlet box, achieving a fully sealed and leak-proof effect. The filter can filter all the gas entering the air supply outlet box cavity, while achieving a fully sealed and leak-proof effect. Several evenly distributed air inlets help guide all the gas along a characteristic direction, allowing the gas to be delivered in a regular manner, achieving a high-efficiency air supply effect, and solving the problems mentioned in the above-mentioned technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully sealed high-efficiency air supply device, which includes an air supply outlet box. The air supply outlet box is a hollow cavity structure with an opening at the bottom and is rectangular in shape. A guide plate and a filter located below the guide plate are installed inside the cavity of the air supply outlet box. The filter is placed horizontally, and all four sides of the filter are in contact with the inner wall of the cavity of the air supply outlet box. There is no gap between the filter and the inner wall of the cavity of the air supply outlet box. The filter can achieve a fully sealed and leak-proof effect, so that the filter can filter all the gas entering the cavity of the air supply outlet box. A diffuser is provided at the bottom of the air supply outlet box. The diffuser includes a diffuser plate with several air inlets.

[0006] Preferably, a regulating valve is installed on the top of the air outlet box. The regulating valve is located above the guide plate, and the guide plate is close to the regulating valve. Therefore, when the regulating valve is opened, the air to be filtered can enter the cavity of the air outlet box and be delivered to the filter after passing through the guide plate.

[0007] Preferably, an air inlet is provided through the top of the air outlet box from top to bottom. The air inlet is connected to the regulating valve. A guide plate is set inside the air inlet so that all the gas entering the air outlet box cavity is guided by the guide plate, which facilitates the improvement of gas flow efficiency. The shape of the micro-holes on the guide plate is the same as the shape of the air inlet hole, so it can guide the flow efficiently.

[0008] Preferably, multiple support legs are fixed inside the cavity of the air outlet box, the multiple support legs are symmetrical to both ends of the filter, and each of the multiple support legs is provided with a limiting groove.

[0009] Preferably, the bottom of the filter is set in the limiting groove, and the top of the filter is formed with a zero-leakage knife groove. The limiting groove can limit the position of the filter, ensuring that the filter remains stable in the air outlet box cavity. The zero-leakage knife groove can make the filter and the air outlet box tightly connected, so there are no gaps, ensuring a full seal effect and preventing gas leakage.

[0010] Preferably, several air inlets are evenly distributed on the diffuser plate, and several fixed spare slots are provided on the edge of the diffuser plate. Since the air inlets are evenly distributed, it is beneficial to guide all the gas along a characteristic direction. Therefore, the effect of efficient air supply can be achieved through several air inlets.

[0011] Preferably, multiple lifting lugs are fixed on the upper surface of the air outlet box, and the multiple lifting lugs are evenly distributed on the air outlet box.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a fully sealed high-efficiency air supply device. The fully sealed high-efficiency air supply device includes an air outlet box. The overall structure is simple and reasonably designed. The air outlet box is a hollow cavity structure with an opening at the bottom. The air outlet box is rectangular in shape. A diffuser is provided at the bottom of the air outlet box. The diffuser includes a diffuser plate. Several evenly distributed air inlets are provided on the diffuser plate. Several evenly distributed air inlets help to guide all the gas along a characteristic direction, so that the gas is delivered regularly and quickly. Therefore, high-efficiency air supply can be achieved through several air inlets, which is suitable for widespread use.

[0014] 2. The air outlet box of this utility model is equipped with a guide plate and a filter located below the guide plate. The filter is placed horizontally, and all four sides of the filter are in contact with the inner wall of the air outlet box cavity, so that there is no gap between the filter and the inner wall of the air outlet box cavity. Therefore, the filter can achieve a full seal and leak-proof effect, so that the filter can filter all the gas entering the air outlet box cavity. It not only achieves a relatively complete filtration effect, but also plays a role in full sealing and leak prevention, avoiding the direct delivery of unfiltered gas into the room and causing air pollution. It is highly practical. Attached Figure Description

[0025] Please see Figures 1 to 2 The present invention provides an embodiment of a fully sealed high-efficiency air supply device, which includes an air outlet box 1, an adjusting valve 7 installed on the top of the air outlet box 1, a diffuser 6 provided at the bottom of the air outlet box 1, and multiple lifting lugs 8 fixed on the upper end face of the air outlet box 1, which are evenly distributed on the air outlet box 1.

[0026] Please see Figures 3 to 4The air outlet housing 1 is a hollow cavity structure with an opening at the bottom, and it is rectangular in shape. A guide plate 2 and a filter 3 located below the guide plate 2 are installed inside the cavity of the air outlet housing 1. The filter 3 is horizontally placed, and all four sides of the filter 3 are flush with the inner wall of the cavity of the air outlet housing 1, ensuring no gaps between the filter 3 and the inner wall of the cavity. This achieves a completely sealed and leak-proof effect, allowing the filter 3 to filter all air entering the cavity of the air outlet housing 1. The air supply box 1 is filtered by a regulating valve 7 located above the guide plate 2, with the guide plate 2 close to the regulating valve 7. An air inlet is provided from top to bottom at the top of the air supply box 1, and this air inlet is connected to the regulating valve 7. The guide plate 2 is located inside the air inlet, so that all the gas entering the air supply box 1 cavity is guided by the guide plate 2, thereby improving the gas flow efficiency. Therefore, when the regulating valve 7 is opened, the air to be filtered can enter the cavity of the air supply box 1 and be delivered to the filter 3 after passing through the guide plate 2.

[0027] Please see Figure 5 Multiple support legs 9 are fixed inside the cavity of the air outlet housing 1. The multiple support legs 9 are symmetrical to both ends of the filter 3, and each of the multiple support legs 9 is provided with a limiting groove 4. The bottom of the filter 3 is set in the limiting groove 4, and the top of the filter 3 forms a zero-leakage knife groove 5. The position of the filter 3 can be limited by the limiting groove 4 to ensure that the filter 3 remains stable in the cavity of the air outlet housing 1. The zero-leakage knife groove 5 can make the filter 3 and the air outlet housing 1 tightly connected, so there is no gap, ensuring a full seal effect and preventing gas leakage.

[0028] Please see Figure 6 The diffuser 6 includes a diffuser plate 61 with a plurality of air inlets 62 evenly distributed on the diffuser plate 61. A plurality of fixed spare slots 63 are provided on the edge of the diffuser plate 61. Since the plurality of air inlets 62 are evenly distributed, it is beneficial to guide all the gas along a characteristic direction, so that the gas is delivered regularly and quickly. Therefore, the effect of efficient air delivery can be achieved through the plurality of air inlets 62. In addition, the shape of the micro-holes on the guide plate 2 is the same as the shape of the air inlets 62, so it can guide the air efficiently.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
