Description

Technical Field

[0001] The invention relates to the technical field of secondary gas purification, in particular to a fresh air purification device for a central air conditioner. Background Art

[0002] Central air conditioning refers to a large air-conditioning system, which consists of a main unit and a terminal. The main unit is divided into a water-cooled unit and an air-cooled unit. The terminal equipment mainly consists of an air-conditioning unit and a fan coil unit. Another type of central air-conditioning is a VRV air-conditioning unit that uses refrigerant Freon. The fresh air generated by the central air-conditioning needs to pass through purification equipment to remove harmful substances such as dust, pollen, bacteria, viruses, and harmful gases in the outdoor air to protect our respiratory system and physical health.

[0003] After using the existing purification equipment, there are still the following problems:

[0004] 1. When using purification equipment to purify the fresh air of the central air conditioner, a filter mechanism is usually used for purification. After long-term use, the purification equipment needs to be maintained and the purification mechanism in the purification equipment needs to be removed. The removal methods include disassembly and pull-out. However, both methods stop the purification equipment from working, thereby suspending the purification of the fresh air of the central air conditioner, causing the fresh air to enter the room without being purified, thereby reducing the indoor air quality.

[0005] 2. After the fresh air of the central air-conditioning is purified by the purification equipment, the purification equipment is usually maintained by regular maintenance. However, regular maintenance is easily affected by the quality of the fresh air before purification. If the quality of the fresh air is low before purification, it is easy to increase the degree of pollution to the purification equipment during purification, so that the purification equipment reaches the pollution level required for maintenance before regular maintenance, and then continue to use the purification equipment to purify the fresh air before regular maintenance, which affects the quality of fresh air purification and reduces the purification effect of the purification equipment on the fresh air.

[0055] Working principle:

[0056] Initial limit:

[0057] Before using the device, the user needs to install motor 1 at the top of the drive shaft 32, which serves as the driving source of the drive shaft 32, and install motor 2 at the end of the rotating shaft 52 away from the control box 51, which serves as the driving source of the rotating shaft 52;

[0058] The user needs to connect an electric valve to one end of the bellows 412 away from the diversion pipe 411, and connect the other end of the electric valve to a water source. At this time, the electric valve is in a closed state.

[0059] The infrared sensor 6 can be an infrared PM2.5 sensor. The user needs to install a controller inside the control block 2, and the controller is electrically connected to the infrared sensor 6. At the same time, the electric valve, the electric push rod 43 and the motor 1 are controllably connected to the controller. The infrared sensor 6 detects particulate matter in the air purified by the purification plate 1 36 or the purification plate 2 39, and converts the detection result into an electrical signal. The electrical signal generated by the infrared sensor 6 is input into the controller. The controller performs a logical judgment on the detection signal sent by the infrared sensor 6 to check whether the detection signal is within the set threshold range, thereby controlling the opening and closing of the electric valve, the electric push rod 43 and the motor 1, and the controller is a controller that can automatically time;

[0060] The user needs to connect a fresh air source to the integrated air inlet pipe at the top of the purification box 1, and the fresh air source is turned on. At the same time, the integrated air outlet pipe at the bottom of the purification box 1 is connected to an external drainage source to introduce the purified fresh air into the central air conditioner.

[0061] The user needs to connect an external treatment agent source to the agent guide tube 510. The treatment agent can be an air cleaner, disinfectant, deodorant, environmentally friendly cleaner, etc. The status of other parts is as follows Figures 1 to 13 As shown;

[0062] Steps for replacing and cleaning the purification board:

[0063] like Fig.11 As shown, the fresh air in the fresh air source enters the integrated air inlet pipe at the top of the purification box 1, and the fresh air enters the inside of the purification box 1 from the integrated air inlet pipe. After being purified by the purification plate 36, the fresh air passes through the area where the infrared sensor 6 is located. Based on the light scattering principle, the infrared sensor 6 generates a hot air flow through the infrared LED light source and the heating resistor to promote the flow of the sampled air. When the particles in the air pass through the infrared light, reflected light is generated. The sensor detects the intensity of the reflected light to determine the concentration of the particles. When it is detected that the concentration of the fresh air particles after being purified by the purification plate 36 exceeds the set threshold range, the infrared sensor 6 controls the motor 1 to start, and its principle is consistent with the above.

[0064] like Figures 3 to 6As shown, after the motor 1 is started, the output shaft of the motor 1 drives the drive shaft 32 to rotate clockwise, and the drive shaft 32 drives the gear 33 to rotate clockwise when rotating clockwise. Since the rack 1 34 and the rack 2 37 are both meshed with the gear 33 for transmission, the gear 33 drives the rack 1 34 and the rack 2 37 to move relative to each other when rotating clockwise. The rack 1 34 and the rack 2 37 synchronously drive the transmission frame 1 35 and the transmission frame 2 38 to move relative to each other during the relative movement. The transmission frame 1 35 and the transmission frame 2 38 synchronously drive the purification plate 1 36 and the purification plate 2 39 to move relative to each other during the relative movement, thereby the purification plate 1 36 is moved to the inside of the processing box 41, and the purification plate 2 39 is moved to the outside of the purification box 1, and then the space where the purification plate 1 36 and the purification plate 2 39 are located is replaced, so that the new purification plate is automatically replaced according to the concentration of the purified fresh air particles, so that the user does not need to replace the purification plate 1 36 and the purification plate 2 39 through regular maintenance, thereby reducing the time and labor intensity of manual operation, reducing human errors, ensuring that the purification plate is installed correctly, so that the concentration of fresh air particles entering the conical purification seat 513 is within a normal range, thereby reducing the wear on the conical purification seat 513;

[0065] like Figure 6 As shown, when the rack 1 34 and the rack 2 37 are in relative motion, the rack 1 34 is in a state of being away from the purification box 1, and the rack 2 37 is in a state of being close to the purification box 1. When the rack 1 34 is away from the purification box 1, it drives the driving frame 310 away from the purification box 1, and when the driving frame 310 is away from the purification box 1, it drives the control seat 311 away from the purification box 1. Figure 4 As shown, the driving block 313 is slidably connected with the limit block 312, so the control seat 311 synchronously lifts the driving block 313 when it is away from the purification box 1, so that the driving block 313 moves upward, and the driving block 313 drives the control frame 315 to move upward when it moves upward, and the control frame 315 drives other structures of the multi-layer processing mechanism except the processing box 41 to move upward when it moves upward, so as to adjust the distance between the processing plate 49 and the top of the purification plate 1 36, so that the bottom end of the processing plate 49 and the top end of the purification plate 1 36 are on the same horizontal line. After the purification plate 1 36 and the purification plate 2 39 are replaced, the fresh air inside the purification box 1 is purified by the purification plate 2 39 when it reaches the area where the infrared sensor 6 is located. When the fresh air purified by the purification plate 2 39 is detected by the infrared sensor 6 as not reaching the set threshold range, the infrared sensor 6 controls the motor 1 to turn off, start the electric push rod 43 and the electric valve, and make the electric push rod 43 start working, as shown in FIG. Figure 8As shown, the piston rod inside the electric push rod 43 drives the push block 44 away from the electric push rod 43, and the push block 44 drives the mounting block 45 away from the electric push rod 43 when it is away from the electric push rod 43, and the mounting block 45 drives the processing plate 49 away from the electric push rod 43 when it is away from the electric push rod 43, and the processing plate 49 drives the processing seat 410 away from the electric push rod 43 when it is away from the electric push rod 43, and after the electric valve is opened, the water in the water source is introduced into the bellows 412 through the electric valve, and the water is introduced from the bellows 412 into the inside of the shunt pipe 411, and the water is introduced from the inside of the shunt pipe 411 into the processing chamber 1 and the processing chamber 2 respectively, and the water in the processing chamber 2 is sprayed out from the processing hole 2 at the bottom of the processing seat 410. The top of the purification plate 36 is flushed, and the water in the processing chamber 1 is sprayed from the processing hole 1 at the bottom of the processing plate 49 to the top of the purification plate 36 after flushing, thereby flushing the top of the purification plate 36 twice. Since the bottom of the processing plate 49 and the top of the purification plate 36 are on the same horizontal line, and the processing plate 49 is in the process of moving away from the electric push rod 43, the impurities and water on the top of the purification plate 36 are scraped off by the bottom of the processing plate 49, thereby cleaning the top of the purification plate 36, and then removing the dust and pollutants accumulated on the top of the purification plate 36, preventing bacteria from breeding, and improving the cleaning effect of the top of the purification plate 36 through secondary flushing;

[0066] like Figure 8 As shown, the mounting block 45 drives the processing block 47 away from the electric push rod 43 when it is away from the electric push rod 43. The processing block 47 is compressed by the purification plate 36 close to the mounting block 45 when it is away from the electric push rod 43, so that the processing block 47 is compressed into the receiving groove at the bottom end of the mounting block 45, and the bottom end of the processing block 47 conflicts with the top end of the purification plate 36. When the processing block 47 is compressed into the receiving groove, the elastic column 46 is compressed synchronously, so that the elastic column 46 is deformed. When the processing block 47 moves away from the electric push rod 43, its bottom end moves to face the purification hole 1, and at this time, the bottom end of the processing block 47 loses the pressure from the purification plate The top of the cleaning hole 36 is resisted, so that the processing block 47 is rebounded into the purification hole 1 by the rebound force of the elastic column 46, so as to remove the impurities in the purification hole 1 to prevent the purification hole 1 from being blocked, and the processing block 47 drives the bristles 48 to move downward when rebounding into the purification hole 1, so that the bristles 48 clean the inner wall of the purification hole 1. The cleaning hole 1 is cleaned by the processing block 47 and the bristles 48, which can effectively remove the dust, dirt and other blockages in the purification hole 1, restore the purification function of the purification hole 1, ensure that the purification hole 1 is unobstructed, help improve the purification efficiency of the fresh air, and ensure the smooth circulation of the fresh air;

[0067] Double-layer purification steps:

[0068] Before using the device, the user needs to turn on the power of the motor 2, and the motor 2 starts to work. The output shaft of the motor 2 drives the shaft 52 to rotate, and the shaft 52 drives the cam 53 to rotate when rotating. Fig. 9 As shown, the driving plate 54 is slidably connected to the inside of the control box 51, and the driving plate 54 is located on one side of the cam 53, so that the cam 53 synchronously pushes the driving plate 54 away from the rotating shaft 52 when rotating. Fig.10 As shown, the drive plate 54 compresses the spring 2 55 when it is away from the rotating shaft 52, causing the spring 2 55 to deform, as shown in FIG. Fig.11 As shown, the driving plate 54 synchronously drives the connecting frame 56 away from the rotating shaft 52 when it is away from the rotating shaft 52, and the connecting frame 56 synchronously drives the friction frame 57 to move at the top of the conical purification seat 513 when it is away from the rotating shaft 52. When the cam 53 rotates to 180 degrees and returns to the position shown in FIG. Fig.11 In the state shown, the driving plate 54 is no longer pushed by the cam 53, and the spring 2 55 loses the compression from the driving plate 54, so that the driving plate 54 is moved closer to the rotating shaft 52 by the rebound force of the spring 2 55, thereby driving the friction frame 57 back to Fig.11 The position shown in the figure makes the friction frame 57 in the reciprocating motion at the top of the conical purification seat 513, and then the reciprocating motion of the friction frame 57 is used to generate friction at the top of the conical purification seat 513, so that the friction frame 57 uses the friction static principle to form an electrostatic area at the top of the conical purification seat 513, and then the fresh air purified by the purification hole 1 is adsorbed by the electrostatic area at the top of the conical purification seat 513. The use of electrostatic adsorption can further optimize the quality of the fresh air, and adsorb the tiny particles in the fresh air at the top of the conical purification seat 513 to avoid the tiny particles from contacting the purification hole 2, thereby preventing the tiny particles from causing wear to the purification hole 2, further improving the purification effect of the fresh air, and preventing the tiny particles from clogging the purification hole 2, thereby ensuring that the purification hole 2 will not reduce the amount of fresh air passing through due to clogging, so that the fresh air maintains the maximum air volume to enter the conical purification seat 513;

[0069] like Fig.12 and Fig.13As shown, the cam 53 synchronously drives the control cylinder 58 to rotate when it rotates, and the control cylinder 58 synchronously drives the purification tube 511 to rotate when it rotates, and the purification tube 511 drives the spray plate 512 to rotate when it rotates, so as to form an electrostatic area at the top of the conical purification seat 513 while promoting the flow of fresh air inside the conical purification seat 513, and the user connects the treatment agent source before using the device, and the treatment agent in the treatment agent source enters the inside of the guide tube 510, and the treatment agent enters the drainage cavity in the introduction ring 59 from the inside of the guide tube 510, and the treatment agent enters the inside of the control cylinder 58 through the drainage hole from the drainage cavity, and the treatment agent enters the purification tube from the inside of the control cylinder 58 Inside 511, the treatment agent enters the purification chamber in the spray plate 512 from the purification pipe 511, and then the treatment agent is sprayed from the spray hole to the inside of the conical purification seat 513 to mix with the fresh air, and the rotation of the spray plate 512 drives the gas flow inside the conical purification seat 513, thereby promoting the treatment agent to quickly contact the fresh air inside the conical purification seat 513, thereby accelerating the mixing speed of the treatment agent and the fresh air, thereby improving the quality of the fresh air, and then accelerating the speed at which the fresh air is exported from the conical purification seat 513, so that the fresh air is introduced into the drainage source through the integrated air outlet pipe at the bottom of the purification box 1, and then the purified fresh air is introduced into the central air conditioner.
