Description

Technical Field

[0001] This utility model relates to the field of laboratory ventilation equipment technology, and in particular to a low-carbon, energy-saving spray-type laboratory ventilation equipment. Background Technology

[0002] Spray-type laboratories can also be used to test the protective performance of product casings under water spray conditions, ensuring the product's performance during storage, transportation, and use in rainy climates. This type of equipment is widely used in electronics, transportation, aerospace, automotive, and electrical industries to test the waterproof performance of electronic equipment, automotive parts, lighting fixtures, and other products.

[0003] After use in the laboratory, the equipment needs to be sprayed to allow the atomized water mist to absorb dust in the air and provide ventilation. Existing spray-type laboratory ventilation equipment is equipped with fans for better ventilation. At the same time, the laboratory's airtightness must be ensured when ventilation is not required. This places higher demands on ventilation and airtightness, requiring the laboratory to be unsealed when ventilation is needed. Therefore, a low-carbon and energy-saving spray-type laboratory ventilation equipment is needed. Utility Model Content

[0004] The purpose of this utility model is to solve the problems raised by the prior art by proposing a low-carbon and energy-saving spray-type laboratory ventilation equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A low-carbon, energy-saving spray-type laboratory ventilation device includes a laboratory body, a water tank on one side of the laboratory body, an air inlet and an exhaust pipe fixedly connected inside the laboratory body, a spiral atomizing nozzle fixedly connected to the inner top wall of the laboratory body, rotating discs rotatably connected to the surfaces of both the air inlet and exhaust pipes, fans rotatably mounted on the inner walls of both the air inlet and exhaust pipes, a filter screen fixedly connected to the surface of the air inlet, an activated carbon plate fixedly connected to the surface of the exhaust pipe, and a sealing ventilation mechanism installed on the inner top wall of the laboratory body.

[0007] Preferably, the sealing and ventilation mechanism includes a waterproof motor fixedly connected to the top wall of the laboratory body, a first bevel gear fixedly connected to the output end of the waterproof motor, and a second bevel gear fixedly connected to one end of the fan, wherein the first bevel gear meshes with the second bevel gear.

[0008] Furthermore, a drive plate is fixedly connected to the surface of the fan, a force-applying plate is rotatably connected to the inner wall of the drive plate, and an arc-shaped telescopic rod is fixedly installed on the surfaces of the drive plate and the force-applying plate.

[0009] Preferably, a plurality of arc-shaped blocks are fixedly connected to the surface of the rotating disk, and fixed blocks are fixedly connected to the surfaces of the air inlet and exhaust pipes. Springs are fixedly connected to the surfaces of the rotating disk and the fixed blocks.

[0010] Furthermore, the inner walls of the air intake and exhaust pipes are rotatably connected to multiple sector plates, one end of which is fixedly connected to a friction ring, which makes frictional contact with the surface of the rotating disk.

[0011] Preferably, a water pump is fixedly installed on the upper surface of the water tank, the water inlet of the water pump extends to the bottom of the water tank, the water outlet of the water pump is fixedly connected to a water suction pipe, one end of the water suction pipe extends into the interior of the spiral atomizing nozzle, and a floor drain pipe is installed on the inner bottom wall of the laboratory body.

[0012] The beneficial effects of this utility model are as follows:

[0013] When the fan rotates, the drive plate rotates the force plate, applying pressure to the contact surface of the arc-shaped block. This causes the rotating disk to rotate under pressure, which in turn causes the friction ring to rotate, changing the angle of multiple sector plates. This allows outside air to pass through the filter screen and enter the main body of the laboratory. When the force plate separates from the surface of the arc-shaped block, the rotating disk resets under the pull of the spring, thus sealing the air inlet of the air inlet. The advantage of this is that it seals the main body of the laboratory when ventilation is not possible, and when ventilation is possible, the angle of the sector plates is adjusted, and the fan rotates to perform ventilation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-5 A low-carbon, energy-saving spray-type laboratory ventilation device includes a laboratory body 1, a water tank 2 on one side of the laboratory body 1, an air inlet 6 and an exhaust 8 fixedly connected inside the laboratory body 1, a spiral atomizing nozzle 5 fixedly connected to the inner top wall of the laboratory body 1, a rotating disk 19 rotatably connected to the surface of both the air inlet 6 and the exhaust 8, a fan 21 rotatably installed on the inner wall of both the air inlet 6 and the exhaust 8, a filter screen 18 fixedly connected to the surface of the air inlet 6, an activated carbon plate 7 fixedly connected to the surface of the exhaust 8, and a sealing ventilation mechanism installed on the inner top wall of the laboratory body 1.

[0022] By setting spiral atomizing nozzles 5, which are installed at multiple angles, the sprayed atomized gas is more evenly filled into the laboratory body 1. By setting a fan 21, which is electrically driven to rotate, the outside air is guided into the laboratory body 1 through the air intake 6. By setting a filter screen 18, dust in the air is filtered out. By setting an activated carbon plate 7, impurities in the air are adsorbed and treated. By setting a sealed ventilation mechanism, the system switches between sealing and ventilation. When using the laboratory body 1, the air is sealed. After the experiment, ventilation is achieved.

[0023] In this utility model, reference Figure 2 and Figure 3 The sealed ventilation mechanism includes a waterproof motor 10 fixedly connected to the top wall of the laboratory body 1. The output end of the waterproof motor 10 is fixedly connected to a first bevel gear 11, and one end of the fan 21 is fixedly connected to a second bevel gear 12. The first bevel gear 11 and the second bevel gear 12 mesh.

[0024] By setting a waterproof motor 10, the first bevel gear 11 is driven to rotate, and by setting the first bevel gear 11, the second bevel gear 12 and the fan 21 are driven to rotate.

[0025] In this utility model, reference Figure 3 A drive plate 17 is fixedly connected to the surface of the fan 21, and a force-applying plate 14 is rotatably connected to the inner wall of the drive plate 17. An arc-shaped telescopic rod 13 is fixedly installed on the surfaces of the drive plate 17 and the force-applying plate 14.

[0026] By setting the driving plate 17, the force-applying plate 14 can move together. By setting the arc-shaped telescopic rod 13, the force-applying plate 14 can be reset well after encountering resistance.

[0027] In this utility model, reference Figure 3 Multiple arc-shaped blocks 20 are fixedly connected to the surface of the rotating disk 19. Fixed blocks 16 are fixedly connected to the surfaces of the air inlet 6 and the exhaust pipe 8. Springs 15 are fixedly connected to the surface of the rotating disk 19 and the surface of the fixed blocks 16.

[0028] By setting up the arc-shaped block 20, when the surface of the force plate 14 comes into contact with the surface of the arc-shaped block 20, it drives the rotating disk 19 to rotate. By setting up the spring 15, the rotating disk 19 is pulled to quickly return to its original position.

[0029] In this utility model, reference Figure 4 and Figure 5 Multiple sector plates 22 are rotatably connected to the inner walls of the air intake 6 and the exhaust 8. A friction ring 23 is fixedly connected to one end of the sector plate 22, and the friction ring 23 is in frictional contact with the surface of the rotating disk 19.

[0030] By setting multiple sector plates 22, when the sector plates 22 rotate at an angle, outside air can be sent into the laboratory body 1 through the air inlet 6. By setting friction rings 23, multiple rotating disks 19 are driven to rotate at an angle.

[0031] In this utility model, reference Figure 1 and Figure 2 A water pump 3 is fixedly installed on the upper surface of the water tank 2. The water inlet of the water pump 3 extends to the bottom of the water tank 2. A water pump pipe 4 is fixedly connected to the water outlet of the water pump 3. One end of the water pump pipe 4 extends into the interior of the spiral atomizing nozzle 5. A floor drain pipe 9 is installed on the inner bottom wall of the laboratory body 1.

[0032] By setting up a water pump 3, the clean water in the water tank 2 is sent to the spiral atomizing nozzle 5 through the water pumping pipe 4, and a floor drain pipe 9 is installed.

[0033] Working principle: When using the main body 1 of the laboratory, multiple sector plates 22 are in contact with each other to maintain the air seal inside the main body 1. After the experiment is completed, the water pump 3 is started to send the clean water in the water tank 2 into the spiral atomizing nozzle 5 through the water pipe 4. The clean water is sprayed out through the spiral atomizing nozzle 5 for atomized dust collection. At this time, the waterproof motor 10 can be started. The output end of the waterproof motor 10 drives the first bevel gear 11 to rotate. The first bevel gear 11 drives the fan 21 to rotate through the second bevel gear 12. The rotation of the fan 21 drives the force plate 14 to rotate through the drive plate 17. The force plate 14 applies pressure to the contact surface with the arc block 20, causing the rotating disk 19 to rotate under the force. When the force plate 14 is resisted, it bends through the arc-shaped telescopic rod 13 to avoid the resistance. The rotating disk 19 rotates, causing the friction ring 23 to rotate, changing the angle of the corresponding sector plate 22, so that the outside air can be filtered through the filter screen 18 and enter the laboratory body 1. The air inside the laboratory body 1 is transported through the filter of the activated carbon plate 7. When the force plate 14 separates from the surface of the arc block 20, the rotating disk 19 is reset under the pulling action of the spring 15, realizing the sealing of the air inlet of the air inlet 6. With the above structure, when the fan 21 is not rotating, multiple sector plates 22 can seal the air inlet 6. When ventilation is performed, the angle of the sector plate 22 is automatically rotated to perform ventilation operation.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
