[0024] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0025] An embodiment of the present invention provides a high-grade clean laboratory, such as Figures 1-6 As shown, it includes a clean room 1, including a clean room 1 and a filter box 2. The interior of the clean room 1 is partitioned into a main room 3 and a secondary room 4. An air inlet pipe 5 is connected to the lower left side of the filter box 2, and a connecting pipe 6 is installed on the upper right side of the filter box 2. One of the pipe orifices of the connecting pipe 6 is connected to an air delivery pipe 7. An air conditioner 8 is installed on the top of the main room 3. The air delivery pipe 7 is connected to the air inlet of the air conditioner 8. A water delivery pipe 9 is installed at the drain outlet of the air conditioner 8. The other end of the water delivery pipe 9 is connected to the upper left side of the filter box 2. A sewage discharge pipe 10 is connected to the bottom of the filter box 2. A filter screen frame 11 is installed on the inner side wall of the filter box 2. A connecting shaft 12 is rotatably installed at the top end inside the filter box 2. A brush plate 14 is installed on the outer side wall of the connecting shaft 12 through a bracket 13. The brush plate 14 is in contact with the lower surface of the filter screen frame 11. A motor 15 is installed on the top of the filter box 2. The output shaft of the motor 15 is connected to the top of the connecting shaft 12. This laboratory is composed of a clean room 1 and a filter box 2. When dust removal is carried out in the clean room 1, the air conditioner 8 can be started. The air conditioner 8 inhales air through the air delivery pipe 7. When the air delivery pipe 7 is in operation, negative pressure is generated inside the filter box 2, and outside air is inhaled from the air inlet pipe 5. The inhaled air is transported upward from the bottom of the filter box 2. The air will pass through the filter screen frame 11, and the filter screen frame 11 can filter the dust in the air, thereby ensuring that the air blown out by the air conditioner 8 is clean. When the air conditioner 8 is used for a long time, a large amount of dust will be generated on the surface of the filter screen frame 11 of the filter box 2 and block it. Here, the condensate drain outlet of the air conditioner 8 is connected to the water delivery pipe 9, and since the water delivery pipe 9 is connected to the filter box 2, the condensate water will flow into the filter box 2 and flow downward through the surface of the filter screen frame 11. When the condensate water flows, the dust on the surface of the filter screen frame 11 will be brought into the sewage discharge pipe 10, and at the same time, the filtering effect of the filter screen frame 11 is improved. At the same time, the motor 15 can be started. The motor 15 drives the brush plate 14 to rotate through the connecting shaft 12. When the brush plate 14 rotates, the dust that is difficult to wash off on the surface of the filter screen frame 11 can be scraped off, thereby playing an auxiliary cleaning role and improving the cleaning effect of the filter screen frame 11. This device washes the filter box 2 by connecting the condensate water generated by the operation of the air conditioner 8 to the filter box 2, realizing the automatic cleaning of the filter box 2, and at the same time, cooperating with the brush plate 14 can ensure that the filter screen frame 11 can be effectively cleaned.

[0026] Three groups of filter screen frames 11 are provided, and the three groups of filter screen frames 11 are equidistantly distributed from top to bottom. The pore diameters of the three groups of filter screen frames 11 gradually decrease from bottom to top. By providing three groups of filter screen frames 11 with different filtering pore diameters, different sizes of dust particles in the air can be filtered. At the same time, since the filtered dust is getting smaller and smaller, the dust can fall out from the mesh holes of the filter screen frame 11 below it during cleaning.

[0027] The inner wall of the filter box 2 is set to be rectangular, and the left and right side walls of the filter box 2 are provided with positioning slots that are compatible with the width of the filter frame 11. The filter frame 11 is slidably inserted into the inner wall of the filter box 2. The filter frame 11 is composed of a rectangular frame and a circular grid frame, and the frame is provided with a strip groove that is compatible with the diameter of the connecting shaft 12 on the rear side. A partition 16 is installed on the rear side of the inner wall of the filter box 2. The partition 16 is fitted with the frame of the filter frame 11 and the outer wall of the connecting shaft 12. The filter frame 11 is placed in a sliding groove provided on the inner wall of the filter box 2. This setting can make the disassembly and assembly of the filter frame 11 more convenient, and is convenient for the subsequent disassembly and replacement of the filter frame 11. The surface of the filter frame 11 is grooved to meet the positioning and insertion of the connecting shaft 12. The upper and lower layers of the filter frame 11 can be sealed by providing the partition 16 to prevent air with dust from entering through the gap.

[0028] A fan 19 is installed on the outside of the top of the sub-chamber 4, and an air trough 20 is installed on the inside of the top of the sub-chamber 4. The air outlet of the fan 19 is communicated with the air trough 20, and an air inlet pipe 21 is connected to the air inlet of the fan 19. The other end of the air inlet pipe 21 is connected to the connecting pipe 6. The connecting pipe 6 is set as a three-way pipe and a solenoid valve 17 is installed at the center. By setting up the fan 19, the fan 19 can blow air into the inside of the sub-chamber 4, and the air inlet of the fan 19 is connected to the connecting pipe 6 through the air inlet pipe 21. Before entering the main chamber 3, the staff will first pass through the sub-chamber 4 for blowing and dust removal, and then enter the main chamber 3 after the dust removal is completed. The space of the sub-chamber 4 is small, so the dust removal effect is good and fast, thereby ensuring that the staff will not bring dust when entering the main chamber 3.

[0029] A hanger 18 is installed on the inner wall of the secondary chamber 4. By installing the hanger 18 inside the secondary chamber 4, it is convenient to put in the clean clothes, and the staff can change the clean clothes inside the secondary chamber 4. Dust removal can be carried out during this period to ensure that there is no dust when entering the main chamber 3.

[0030] A dust collecting groove 22 is provided at the inner bottom end of the auxiliary chamber 4, and a connecting pipe 23 is installed at the left end of the dust collecting groove 22. The other end of the connecting pipe 23 is connected to the lower right side of the filter box 2. By providing the dust collecting groove 22, when the auxiliary chamber 4 is blowing and dusting, the air containing dust will pass through the dust collecting groove 22, and then enter the filter box 2 through the connecting pipe 23. After the dust removal is completed, the dust will fall into the sewage pipe 10. When the auxiliary chamber 4 is dusting, the air supply pipe 7 is closed by controlling the solenoid valve 17, and the air inlet pipe 21 is opened. When the main chamber 3 is ventilated and dusted, on the contrary, the air supply pipe 7 is opened and the air inlet pipe 21 is closed.

[0031] There are front chamber doors 24 installed between the main chamber 3 and the auxiliary chamber 4 and on the left side of the clean room 1. There are two groups of front chamber doors 24, and they are all installed for horizontal sliding. An electromagnetic slide rail 25 is installed at the top of the front chamber doors 24. The two groups of front chamber doors 24 are both slidingly opened and closed. By providing the front chamber doors 24, the front chamber doors 24 are composed of two single doors sliding towards each other. This opening and closing method has the advantages of being fast and having good sealing performance. When entering the clean room 1, first open the external front chamber door 24 to enter the auxiliary chamber 4, and then the external front chamber door 24 is closed. After the dust removal is completed, the internal front chamber door 24 is opened. At this time, the dust inside the auxiliary chamber 4 and on the staff's clothing has been removed, so that external dust will not enter the clean room 1.

[0032] There are rear chamber doors 26 installed on the right side of the main chamber 3. There are two groups of rear chamber doors 26, and they are all rotationally opened and closed. By providing the rear chamber doors 26, the rear chamber doors 26 can be opened when the equipment needs to be moved. Moreover, the opening space of the rear chamber doors 26 is relatively large, so it is convenient to move larger equipment. And the fast opening and closing of the front chamber doors 24 is convenient for the staff to enter and exit.
