[0034] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0036] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] like Figure 1 and Figure 2 and Figure 3 As shown, it includes a sealed box body 1, an air supply component 2 and an air outlet component 3. The air supply component 2 and the air outlet component 3 are arranged in the box body 1, and the air outlet component 3 is connected to the air supply component 2.

[0038] The air supply component 2 is located at the bottom of the box body 1, and the air outlet component 3 is located at the upper part of the box body 1, and the air flow flows from the bottom to the upper part.

[0039] The air supply assembly 2 includes a first fan 21, a temperature control tube 22 for medium circulation, a first filter 23 and a second filter 24. The temperature control tube 22 is arranged between the first filter 23 and the second filter 24. A partition plate 4 is also arranged at the bottom of the box body 1. The first fan 21 is arranged on the upper surface of the partition plate 4. When the first fan 21 is started, the first fan 21 starts to inhale air.

[0040] The two ends of the first filter 23 abut against the partition plate 4 and the bottom of the box 1 respectively, and the two ends of the second filter 24 abut against the partition plate 4 and the bottom of the box 1 respectively. The area below the partition plate 4 is divided into two parts by the first filter 23 and the second filter 24. The medium circulating in the temperature control tube 22 is ice water.

[0041] A vent 40 is provided on the partition plate 4, and the suction end of the first fan 21 is aligned with the vent 40. The vent 40 and the second filter 24 are located on the same side. The gas first passes through the first filter 23, and then the temperature control tube 22 is located in the flow direction of the gas. Due to heat transfer, the heat of the gas is taken away by the ice water through the temperature control tube 22, and the gas passing through the second filter 24 is gas with too low temperature.

[0042] The air outlet assembly 3 includes a first filter 31 for gas purification. The air outlet end of the first fan 21 is connected to the air inlet end of the first filter 31 . The cold air passing through the first fan 21 is filtered again by the first filter 31 .

[0043] An air inlet 5 is provided at the bottom of the box body 1, and the air inlet 5 and the first filter 23 are located on the same side. The gas enters from the air inlet 5, passes through the first filter 23, and then passes through the area where the temperature control tube 22 is located. The gas contacts the outer wall of the temperature control tube 22, and then passes through the second filter 24, and then passes through the vent 40 to enter the first fan 21. The cold air comes out of the first fan 21 and enters the first filter 31, and then comes out of the first filter 31. An air outlet 6 is provided on the upper part of the box body 1. The outlet end of the first filter 31 is communicated with the air outlet 6. The cold air comes out of the first filter 31 and goes out from the air outlet 6. In this way, the cold air is discharged.

[0044] The air inlet 5 and the air vent 40 are respectively located on both sides of the frame 25, and the air vent 40 is located above the air inlet 5, but the air vent 40 and the air inlet 5 are separated by the frame 25, and the first filter 23 forms an angle with the bottom of the box body 1, so that when the gas comes in from the air inlet 5, the first filter 23 has a larger area for gas filtering, and the gas directly enters the first filter 23 when it comes in and rises. A small amount of gas rises to the upper part of the first filter 23 for filtration, and an angle is formed between the second filter 24 and the partition plate 4. The frame 25 is obliquely arranged at the bottom of the partition plate 4, and the second filter 24 is arranged in parallel with the first filter 23. The cooling gas comes out of the second filter 24 and directly rises from the air vent 40 to enter the first fan 21. The inclined arrangement of the first filter 23 and the second filter 24 can play a guiding role, and can also increase the filtration area, so that the gas can be filtered quickly.

[0045] like Figure 4 and Figure 5 As shown, a water collecting trough 7 is also provided at the bottom of the box body 1, and the water collecting trough 7 is arranged in parallel with the bottom of the second filter 24. When the gas becomes cold after passing through the first filter 23 and the second filter 24, condensed water will drip from the second filter 24. The cold air rises, and condensed water will also drip around the vent 40 and the bottom of the partition plate 4. The vent 40 is located above the open end of the water collecting trough 7, so the condensed water falls into the water collecting trough 7. A water outlet 70 is provided at the bottom of the water collecting trough 7, and the condensed water gathered in the water collecting trough 7 is discharged from the water outlet 70.

[0046] The air supply component 2 also includes a second fan 26, which is arranged on the partition plate 4. The vents 40 are arranged as needed and there is no limit on the number. The suction end of the second fan 26 is aligned with the vents 40, and two adjacent vents 40 are respectively connected to the suction ends of the first fan 21 and the second fan 26. The air outlet component 3 also includes a second filter 32. The air inlet end of the second filter 32 is connected to the air outlet end of the second fan 26, and the air outlet end of the second filter 32 is connected to the air outlet 6.

[0047] The air outlet component 3 also includes a first pipe 33 and a second pipe 34. The first pipe 33 and the second pipe 34 have the same structure and shape. The air inlet end of the first pipe 33 is smaller than the air outlet end, and the air inlet end of the second pipe 34 is smaller than the air outlet end. The two ends of the first pipe 33 are respectively connected to the air outlet end of the first fan 21 and the air inlet end of the first filter 31, so that the cold air passing through the first pipe 33 can be fully filtered by the first filter 31. The contact area between the cold air and the first filter 31 is large, and more filtering can be performed at one time. The two ends of the second pipe 34 are respectively connected to the air outlet end of the second fan 26 and the air inlet end of the second filter 32, so that the cold air passing through the second pipe 34 is fully filtered by the second filter 32.

[0048] The first duct 33 and the second duct 34 are arranged in parallel, and divide the box body 1 into a lower cavity 11 and an upper cavity 12. The lower cavity 11 and the upper cavity 12 are not connected. The first duct 33 and the second duct 34 play a sealing role. The air supply component 2 is located in the lower cavity 11, and the air outlet component 3 is located in the upper cavity 12. The air outlet component 3 also includes a guide plate 35. The guide plate 35 is obliquely arranged above the air outlet ends of the first filter 31 and the second filter 32. Then, the cold air filtered out of the first filter 31 and the second filter 32 will touch the obliquely arranged guide plate 35 when rising, and the top of the guide plate 35 is close to the air outlet 6. Therefore, after rising, the cold air is guided along the shape of the guide plate 35, that is, after the cold air rises and reaches the guide plate 35, the cold air begins to turn, and the cold air flows to the air outlet 6, and the cold air flows out from the air outlet 6.

[0049] An opening 8 is provided on the top of the box body 1, and the opening 8 and the air outlet 6 are respectively located on both sides of the guide plate 35. An auxiliary cavity 9 is provided at the bottom of the opening 8, and the auxiliary cavity 9 and the upper cavity 12 are respectively located on both sides of the guide plate 35, the air outlet 6 and the upper cavity 12 are located on one side, and the opening 8 and the auxiliary cavity 9 are located on one side.

[0050] An air inlet cavity 15 is provided on the outside of the first filter 23, an air outlet cavity 16 is provided on the outside of the second filter 24, the air inlet 5 is located at the bottom of the air inlet cavity 15, the air inlet 5 is communicated with the air inlet cavity 15, the air vent 40 is located at the top of the air outlet cavity 16, the gas coming in from the air inlet 5 is first in the air inlet cavity 15, and the cold air coming out of the second filter 24 is first in the air outlet cavity 16, and the first filter 23 and the second filter 24 can be replaced regularly.

[0051] A first wall panel 13 and a second wall panel 14 are respectively provided on both sides of the box body 1. The first wall panel 13 encloses the first outer wall of the box body 1 to form a first channel 17. The second wall panel 14 encloses the second outer wall of the box body 1 to form a second channel 18. The two ends of the first channel 17 are respectively connected to the air inlet chamber 15 and the auxiliary chamber 9, and the two ends of the second channel 18 are respectively connected to the air inlet chamber 15 and the auxiliary chamber 9. A first side port 19 and a second side port 20 are respectively provided on the two side walls of the box body 1. The first side port 19 is respectively connected to the first channel 17 and the auxiliary chamber 9, and the second side port 20 is respectively connected to the second channel 18 and the auxiliary chamber 9.

[0052] Because the air inlet 5 is arranged at the bottom of the box body 1, during installation, in some occasions, the air inlet 5 may not be smooth, so air is taken in from the opening 8, and some particles of dust fall into the auxiliary chamber 9. Then the gas enters from the first side port 19 and the second side port 20, and enters the first channel 17 and the second channel 18 respectively, and finally enters the air inlet chamber 15 and passes through the first filter screen 23.

[0053] A surrounding wall 81 is disposed around the opening 8 , and the surrounding wall 81 protrudes upward from the upper surface of the box body 1 .

[0054] The first filter 23 and the second filter 24 are relatively arranged on both sides of the frame 25, and the temperature control tube 22 is bent and arranged in the frame 25. The temperature control tube 22 is located in the area enclosed by the first filter 23 and the second filter 24. The bent setting of the temperature control tube 22 can contact the gas more, thereby minimizing the gas temperature.

[0055] like Figure 6 As shown, the temperature control tube 22 is arranged in a winding manner, and the extension path of the temperature control tube 22 is bent, so that more heat can be removed.

[0056] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
