Description

Technical Field

[0001] The invention relates to the technical field of central air conditioners, and in particular to a central air conditioner air outlet duct purification and sterilization device. Background Art

[0002] Central air conditioning systems are indispensable air conditioning equipment in modern buildings. The sanitary condition of their air ducts directly affects the indoor air quality and the health of the residents. However, in actual use, dust, bacteria and other microorganisms are easily accumulated inside the central air conditioning air ducts, posing a potential health hazard. In order to solve this problem, the industry generally uses ultraviolet irradiation and high-temperature steam sterilization technology to purify and sterilize the air ducts.

[0003] Ultraviolet sterilization technology mainly relies on the ultraviolet rays emitted by ultraviolet lamps to destroy the DNA or RNA molecular structure in the cells of microorganisms, thereby achieving the purpose of sterilization and disinfection, while high-temperature steam sterilization uses high-temperature steam to penetrate the cell walls of microorganisms, denature and coagulate proteins, and ultimately kill the microorganisms. These two methods each have their own advantages, and when used in combination can significantly improve the sterilization effect.

[0004] However, the current design of central air-conditioning air duct purification and sterilization devices has limitations. The primary limitation is that its automation level is not high, the operation is cumbersome and inefficient, and it needs to be manually executed and communicated with the customer in advance to confirm the air-conditioning status. If the operation is scheduled to be performed at night, the burden on the operator is further increased. Secondly, the device places the filter and ultraviolet lamp directly inside the air outlet duct, resulting in these devices being susceptible to high temperature and high humidity environments when performing high-temperature steam sterilization. Water vapor may penetrate the filter, causing the filter material to become damp and moldy, reducing the filtration efficiency and shortening its life. At the same time, a humid environment may also cause electrical failures of the ultraviolet lamp, such as short circuit of the lamp tube and decreased light intensity, which not only weakens the sterilization effect, but also may bring safety risks. Summary of the invention

[0018] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limitations of the present invention. On the contrary, embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0019] A central air-conditioning air outlet duct purification and sterilization device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0020] like Figure 1-Figure 8 As shown, a central air-conditioning outlet duct purification and sterilization device according to an embodiment of the present invention includes an exhaust duct 1, and also includes a purification and sterilization device 2 arranged on the exhaust duct 1, and the purification and sterilization device 2 includes: The sterilization regulating mechanism 3 and the exhaust seat 4 are respectively arranged on the top of the exhaust duct 1; High-speed sterilization mechanism 5, filtering mechanism 6 and dust-proof breathable plate 7 are sequentially arranged on the inner wall of the exhaust duct 1, and one end of the high-speed sterilization mechanism 5 and the filtering mechanism 6 respectively passes through the top of the exhaust duct 1 and is connected to the sterilization adjustment mechanism 3; The gas measuring seat 8 and the air inlet mechanism 9 are respectively arranged at the bottom of the exhaust duct 1, the gas measuring seat 8 is located outside the high-pressure extinguishing mechanism 5, and the air inlet mechanism 9 is connected to one end of the high-pressure extinguishing mechanism 5 that passes through the bottom of the exhaust duct 1; The ultraviolet sterilization lamp 10 and the filter cartridge 11 are respectively arranged on the sterilization adjustment mechanism 3 and the filter mechanism 6; The sterilization regulating mechanism 3, the exhaust seat 4, the gas measuring seat 8 and the ultraviolet sterilization lamp 10 are respectively connected to the controller 12 arranged on the sterilization regulating mechanism 3 through the bus system to realize data transmission and reception of control instructions.

[0021] It should be noted that the controller 12 described in this embodiment has a built-in timing module (not shown in the figure), and the operation time is set by the timing module to achieve the timed and autonomous operation of the sterilization adjustment mechanism 3, the exhaust seat 4, the gas measuring seat 8 and the ultraviolet sterilization lamp 10.

[0022] It should be noted that the controller 12 described in this embodiment also has a built-in delay module (not shown in the figure). When the operation time is set and the gas measuring seat 8 still detects that the central air conditioner is in operation, the delay module automatically delays the start time of the sterilization adjustment mechanism 3, the exhaust seat 4, the gas measuring seat 8 and the ultraviolet sterilization lamp 10.

[0023] It should be noted that the ultraviolet sterilization lamp 10 described in this embodiment has a timed opening and closing function. After it is moved out of the exhaust duct 1, it will automatically close. After it is moved into the exhaust duct 1, it will automatically open and run intermittently to sterilize the inside of the exhaust duct 1.

[0024] Specifically, the present invention has a reasonable structure and an intelligent monitoring function. It can automatically detect the operating status of the central air-conditioning and automatically start the high-temperature sterilization device when the customer finishes using it or during the preset night time period to effectively sterilize the inside of the exhaust duct 1. During the sterilization process, the present invention can also flexibly adjust the positions of the ultraviolet sterilization lamp 10 and the filter cartridge 11 to effectively prevent high-temperature steam and gas from damaging the ultraviolet sterilization lamp 10 and the filter cartridge 11. Its highly automated characteristics not only eliminate the need for manual supervision, but also greatly improve work efficiency, reduce labor intensity, and demonstrate excellent use results. The present invention is equipped with a gas measuring seat 8, which is specifically used to monitor the operating status of the central air-conditioning, aiming to prevent any possible impact on user experience or equipment The present invention can avoid conflicts between the operation of the two devices, thereby ensuring that the system works efficiently and stably. By cooperating with the controller 12 to realize automatic monitoring, the present invention does not require manual intervention, effectively reduces the need for walking communication and night shift duty, greatly improves work efficiency, reduces labor intensity, and brings excellent use effect; the present invention integrates a sterilization adjustment mechanism 3, which can not only adjust the position of the ultraviolet sterilization lamp 10 to avoid damage by high-temperature steam and gas, but also serves as a power source for the high-speed sterilization mechanism 5 and the filtering mechanism 6, ensuring that the operating speeds of the two are synchronized, and the operation is simple. At the same time, a power source design is also convenient for maintenance and control, and the use effect is good; the present invention is equipped with an exhaust seat 4, whose core function is to monitor and discharge the high-temperature steam and high-temperature gas in the exhaust duct 1 The exhaust seat 4 is provided with a high-precision temperature and humidity sensor 43, which can sense the state of high-temperature steam and high-temperature gas inside the pipeline in real time and accurately, and then accurately adjust the start and stop time of the high-temperature sterilization equipment. At the same time, the exhaust seat 4 draws on the valve-type one-way valve design inside the gas measuring seat 8, which not only ensures the smoothness of gas discharge, but also effectively prevents dust and impurities from invading the pipeline, and keeps the internal environment of the exhaust duct 1 clean; the present invention is provided with a high-precision sterilization mechanism 5 and a filtering mechanism 6, wherein the high-precision sterilization mechanism 5 is responsible for controlling the opening and closing of the internal space at the left end of the exhaust duct 1 and the connection state with the air intake mechanism 9. When it is connected with the air intake mechanism 9, it can automatically perform high-temperature steam sterilization and high-temperature gas drying operations, while the filtering mechanism 6 controls the internal space at the right end of the exhaust duct 1. The opening and closing of the space inside and the precise adjustment of the position of the filter cartridge 11. When performing high-temperature sterilization, the space between the two mechanisms remains relatively sealed to ensure the accuracy of the sterilization range. At the same time, by precisely adjusting the position of the filter cartridge 11, high-temperature steam and gas are prevented from damaging the filter cartridge 11. The high-temperature sterilization mechanism 5 and the filtering mechanism 6 are synchronously triggered by the sterilization adjustment mechanism 3 to ensure that the opening and closing of the space at both ends of the exhaust duct 1 and the position of the filter cartridge 11 are coordinated to achieve excellent use effect; the present invention is equipped with an air intake mechanism 9, which has a simple structure and works in coordination with the high-temperature sterilization mechanism 5 to achieve automatic injection and flexible conversion of high-temperature steam and high-temperature gas. The mechanism can flexibly switch to the high-temperature gas drying mode after completing the high-temperature steam sterilization according to the preset program, which significantly improves the use effect.

[0025] When in use, the gas measuring seat 8 operates according to the instruction, and the gas measuring seat 8 operates to detect whether the central air-conditioning is running. If it is detected that the central air-conditioning is running, it will delay. If it is detected that the central air-conditioning is not running, the data will be sent to the controller 12, and the controller 12 will control the operation of the sterilization adjustment mechanism 3. The operation of the sterilization adjustment mechanism 3 first drives the ultraviolet sterilization lamp 10 to move upward, so that it is moved out of the exhaust duct 1, and then the sterilization adjustment mechanism 3 continues to operate, and synchronously drives the high-speed sterilization mechanism 5 and the filtering mechanism 6 to operate. When the high-speed sterilization mechanism 5 is in operation, it blocks the space inside the left end of the exhaust duct 1, and triggers the operation of the air intake mechanism 9, and is connected with the air intake mechanism 9, and the filtering mechanism 6 During operation, the space inside the right end of the exhaust duct 1 is blocked, and the position of the filter cartridge 11 is adjusted. After the high-speed sterilization mechanism 5 and the filter mechanism 6 are in operation, the space between them remains relatively sealed to ensure the accuracy of the sterilization range. After the high-speed sterilization mechanism 5 is connected to the air intake mechanism 9, the external high-temperature steam first enters the exhaust duct 1 to perform high-temperature steam sterilization on the exhaust duct 1. Then, as the high-speed sterilization mechanism 5 continues to operate, the external high-temperature gas enters the exhaust duct 1 to heat and dry the exhaust duct 1 to prevent water vapor from remaining in the exhaust duct 1. The exhaust seat 4 monitors the status of the high-temperature steam and high-temperature gas in real time, and detects the exhaust air according to the injection time. The total amount of high-temperature steam and high-temperature gas injected into the inside of the duct 1. When the high-temperature steam or high-temperature gas is filled, it will overflow to the outside of the exhaust duct 1 through the exhaust seat 4. The exhaust seat 4 sends the data to the controller 12 after detection. If the high-temperature steam is filled, the connection state is changed, and the high-temperature steam is allowed to stay in the exhaust duct 1 for a set time to achieve the purpose of high-temperature sterilization. If the high-temperature gas is filled, the connection state setting time is extended to allow the high-temperature gas to be continuously injected into the exhaust duct 1 to take away and remove the water vapor inside the exhaust duct 1. After the high-temperature sterilization and high-temperature gas drying operations are completed, the controller 12 controls the sterilization adjustment mechanism 3 to operate The operation of the sterilization regulating mechanism 3 synchronously drives the high-speed sterilization mechanism 5 and the filtering mechanism 6 to operate. When the high-speed sterilization mechanism 5 operates, the space inside the left end of the exhaust duct 1 is opened, and the connection with the air intake mechanism 9 is disconnected. When the filtering mechanism 6 operates, the space inside the right end of the exhaust duct 1 is opened, and the position of the filter cartridge 11 is adjusted to allow the gas to enter the exhaust duct 1 from the left end of the exhaust duct 1, and be discharged from the right end of the exhaust duct 1 after being filtered by the filter cartridge 11. After the operation of the high-speed sterilization mechanism 5 and the filtering mechanism 6 is completed, the sterilization regulating mechanism 3 drives the ultraviolet sterilization lamp 10 to enter the exhaust duct 1, and the ultraviolet sterilization lamp 10 performs ultraviolet sterilization operation on the inside of the exhaust duct 1.

[0028] It should also be noted that the drive motor 38 described in this embodiment is provided with an encoder, and is connected to the controller 12 via a bus system to achieve data transmission and reception of control instructions.

[0029] It should also be noted that after the ultraviolet sterilization lamp 10 described in this embodiment is moved out from the exhaust duct 1 , the bottom of the sealing seat 312 and the inner wall of the exhaust duct 1 are in the same plane.

[0030] Specifically, the structure and connection relationship of the sterilization adjustment mechanism 3 are further explained. When in use, the drive motor 38 operates according to the instruction, the drive motor 38 rotates in the forward direction and synchronously drives the first gear disc seat 33 to rotate, the first gear disc seat 33 rotates and synchronously drives the second gear disc seat 34 to rotate, the second gear disc seat 34 rotates through the synchronous gear 36 and the synchronous toothed belt 37 to synchronously drive the third gear disc seat 35 to rotate, the third gear disc seat 35 rotates and synchronously drives the transmission sub-gear 314 and the transmission main shaft 313 to rotate, because the first one-way transmission device is arranged between the second gear disc seat 34 and the third gear disc seat 35 and the two sets of reciprocating screw rods 39, the two sets of reciprocating screw rods 39 will not rotate, and the first gear disc seat 33 and the transmission main shaft 313 rotate through the second one-way transmission device 57 and the third one-way transmission device 67, and also respectively drive the first main irregular gear 56 and the second main irregular gear 65 to rotate.

[0031] When the driving motor 38 rotates in the opposite direction, the second gear disc seat 34 and the third gear disc seat 35 can synchronously drive the two sets of reciprocating screw rods 39 to rotate through the first one-way transmission. The rotation of the two sets of reciprocating screw rods 39 synchronously drives the slide seat and the fixed frame 310 to rise and fall vertically. The descent of the fixed frame 310 synchronously drives the lamp holder 311, the ultraviolet sterilization lamp 10 and the sealing seat 312 to descend, so that the ultraviolet sterilization lamp 10 enters the exhaust duct 1 for ultraviolet sterilization operation. The rise of the fixed frame 310 synchronously drives the lamp holder 311, the ultraviolet sterilization lamp 10 and the sealing seat 312 to rise, so that the ultraviolet sterilization lamp 10 is moved out of the exhaust duct 1, cleverly avoiding the potential damage of high-temperature steam and high-temperature gas to the ultraviolet sterilization lamp 10, and also facilitates the later maintenance and replacement of the ultraviolet sterilization lamp 10, with good use effect.

[0032] In one embodiment of the present invention, Figure 3 As shown, the exhaust seat 4 includes an upper exhaust seat body 41, a first valve-type one-way exhaust valve 42 and a temperature and humidity sensor 43. The upper exhaust seat body 41 is fixedly connected to the top of the exhaust duct 1, and the bottom of the upper exhaust seat body 41 passes through the interior of the exhaust duct 1 and is connected to the interior of the exhaust duct 1. The first valve-type one-way exhaust valve 42 and the temperature and humidity sensor 43 are arranged on the upper and lower inner walls of the upper exhaust seat body 41. The temperature and humidity sensor 43 is connected to the controller 12 through a bus system to realize data transmission and reception of control instructions.

[0033] Specifically, the structure and connection relationship of the exhaust seat 4 are further explained. The exhaust seat 4 is cleverly designed and consists of an upper exhaust seat body 41, a first valve-type one-way exhaust valve 42 and a temperature and humidity sensor 43. The upper exhaust seat body 41, as the main structure of the entire device, is fixedly connected to the top of the exhaust duct 1, and its bottom penetrates and enters the exhaust duct 1, ensuring that the internal space is unobstructed. The setting of the first valve-type one-way exhaust valve 42 is a highlight of the exhaust seat 4. It adopts a valve-type structure, which can ensure that the gas can only flow in one direction, effectively preventing the occurrence of air backflow, and also effectively preventing dust and impurities from entering the exhaust duct 1, ensuring that the exhaust duct 1 is clean. In addition, the addition of the temperature and humidity sensor 43 has further improved the intelligence level of the exhaust seat 4. The sensor can monitor the temperature and humidity data inside the exhaust duct 1 in real time, and transmit this information to the controller 12 accurately through the bus system. As the "brain" of the entire system, the controller 12 can make intelligent judgments based on the received data and issue corresponding control instructions, thereby achieving precise regulation and good use effect.

[0034] In one embodiment of the present invention, Figure 4-Figure 5 As shown, the high-pressure extinguishing mechanism 5 includes a first frame 51, a first channel 52, a first ball valve body 53, a second ball valve body 54, a first auxiliary transmission gear 55, a first main irregular gear 56, a second one-way transmission device 57, an exhaust hole 58, an air intake plate 59 and an air intake hole 510, wherein the first frame 51 is fixedly connected to the inner wall of the exhaust duct 1 and is located on the inner side of the gas measuring seat 8, the first channel 52 is opened on the surface of the first frame 51, the first ball valve body 53 and the second ball valve body 54 are respectively rotatably connected to the inner wall of the first channel 52, the first auxiliary transmission gear 55 and the first main irregular gear 56 are respectively rotatably connected to the inner wall of the first frame 51 and meshed, and one end of the central axis of the first ball valve body 53 and the second ball valve body 54 respectively penetrates into the first frame 51 and is connected with the first auxiliary transmission gear 55 and the first main irregular gear 5 6, one end of the central axis of the first main irregular gear 56 passes through the top of the exhaust duct 1, and is connected to one end of the central axis of the first gear disc seat 33 through the second one-way transmission device 57, wherein the transmission direction of the second one-way transmission device 57 is opposite to that of the first one-way transmission device, and the exhaust holes 58 are symmetrically arranged on the surface of the first main irregular gear 56, one end of the central axis of the first main irregular gear 56 passes through the bottom of the exhaust duct 1, and is fixedly connected with an air intake disk 59, and two groups of air intake holes 510 are arranged on the surface of the air intake disk 59, and the two groups of air intake holes 510 are symmetrically arranged in opposite directions along the center line of the air intake disk 59, and the two groups of air intake holes 510 are connected to the inside of the two groups of exhaust holes 58 through a plurality of air transmission channels, and the plurality of air transmission channels are respectively arranged inside the second ball valve body 54, inside the central axis on the second ball valve body 54, and inside the air intake disk 59.

[0035] Specifically, the structure and connection relationship of the high-extinguishing mechanism 5 are further explained. When in use, the first toothed disc seat 33 rotates and drives the first main irregular gear 56 to rotate synchronously through the first one-way transmission device. The first main irregular gear 56 rotates and drives the second ball valve body 54 and the first sub-transmission gear 55 to rotate synchronously. The first sub-transmission gear 55 rotates and drives the first ball valve body 53 to rotate synchronously. After the first ball valve body 53 rotates, it is in a closed state and blocks the internal space at the left end of the exhaust duct 1. In the initial case, the second ball valve body 54 only rotates 90° for the first time. After the second ball valve body 54 rotates for the first time, it is in a closed state, and one side of the exhaust hole 58 on the second ball valve body 54 faces Towards the inside of the exhaust duct 1, the high-temperature steam enters the air delivery channel through one group of air inlet holes 510, and is then delivered to the exhaust hole 58 by the air delivery channel, and finally discharged to the inside of the exhaust duct 1 by the exhaust hole 58, and the inside of the exhaust duct 1 is sterilized at high temperature. When the set amount of high-temperature steam is injected into the exhaust duct 1, the excess high-temperature steam will be discharged from the exhaust seat 4. After the temperature and humidity sensor 43 inside the exhaust seat 4 detects the steam, the data is sent to the controller 12, and the controller 12 controls the driving motor 38 to continue to rotate. The driving motor 38 continues to rotate to drive the second ball valve body 54 to rotate 90° for the second time. At this time, the second ball valve body 54 is in an open state, and the first A ball valve body 53 and an exhaust hole 58 for ejecting high-temperature steam are in a closed state, and then the driving motor 38 continues to rotate to drive the second ball valve body 54 to rotate 90° for the third time. At this time, the second ball valve body 54 is in a closed state, and the exhaust hole 58 on the other side of the second ball valve body 54 faces the inside of the exhaust duct 1. The high-temperature gas enters the gas transmission channel through another set of air inlet holes 510, and is then transported to the position of the exhaust hole 58 by the gas transmission channel, and finally discharged to the inside of the exhaust duct 1 by the exhaust hole 58, performing a high-temperature drying operation on the inside of the exhaust duct 1. When the temperature and humidity sensor 43 inside the exhaust seat 4 detects the high-temperature gas, the data is sent to the controller 12, which is controlled by the controller 12. The driving motor 38 stops running and the high-temperature gas injection time is extended. After the set time is over, the controller 12 controls the driving motor 38 to continue rotating. The driving motor 38 continues to rotate to drive the second ball valve body 54 to rotate 90° for the fourth time. After the second ball valve body 54 rotates 90°, the first auxiliary transmission gear 55 and the first main irregular gear 56 cooperate with each other to synchronously drive the first ball valve body 53 to rotate. At this time, the second ball valve body 54 is in an open state, and the first ball valve body 53 is also in an open state. After the first ball valve body 53 is opened, air can circulate inside the left end of the exhaust duct 1, so that the air of the central air conditioner can pass through the first channel 52 and flow toward the dust-proof and breathable plate 7.

[0036] In one embodiment of the present invention, Figure 4 and Figure 6As shown, the filtering mechanism 6 includes a second frame 61, a second channel 62, a third ball valve body 63, a fourth ball valve body 64, a second main irregular gear 65, a second sub-transmission gear 66 and a third one-way transmission device 67, wherein the second frame 61 is fixedly connected to the inner wall of the exhaust duct 1, the second channel 62 is opened on the surface of the second frame 61, the third ball valve body 63 and the fourth ball valve body 64 are respectively rotatably connected to the inner wall of the second channel 62, the second main irregular gear 65 and the second sub-transmission gear 66 are respectively rotatably connected to the inner wall of the second frame 61, and meshingly connected, one end of the central axis of the third ball valve body 63 and the fourth ball valve body 64 respectively penetrates into the second frame 61, and is connected to the second main irregular gear 65 and the second sub-transmission gear 66, one end of the central axis of the second main irregular gear 65 penetrates out of the top of the exhaust duct 1, and is connected to the transmission main shaft 313 through the third one-way transmission device 67; The third one-way transmission device 67 has the same transmission direction as the second one-way transmission device 57; The number of teeth on the first main irregular gear 56 is one quarter of the number of teeth on the first secondary transmission gear 55 , and the number of teeth on the second main irregular gear 65 is one quarter of the number of teeth on the second secondary transmission gear 66 .

[0037] It should be noted that the filter cartridge 11 described in this embodiment is detachably disposed in the through groove of the fourth ball valve body 64 .

[0038] It should also be noted that the third one-way transmission 67, the second one-way transmission 57 and the first one-way transmission are all ratchet one-way transmissions.

[0039] Specifically, the structure and connection relationship of the filter mechanism 6 are further described. During operation, the rotation of the transmission main shaft 313 drives the second main irregular gear 65 to rotate precisely and synchronously through the third one-way transmission device 67. This action chain causes the third ball valve body 63 and the second auxiliary transmission gear 66 (engaged with the second main irregular gear 65) to rotate synchronously. At the same time, the rotation of the second auxiliary transmission gear 66 also drives the synchronous rotation of the fourth ball valve body 64. This series of precise rotation actions ultimately achieves the precise adjustment of the position of the filter cartridge 11, cleverly avoiding the impact of high-temperature steam and high-temperature gas on the filter cartridge. 11 is potentially damaged, which effectively guarantees its service life and filtering efficiency, thereby maintaining the stability of air quality. It is worth noting that the synchronous rotation design of the third ball valve body 63 and the second ball valve body 54 ensures the timely opening and closing of the right end space, perfectly matching the working state of the second ball valve body 54. Similarly, the synchronous rotation mechanism of the fourth ball valve body 64 and the first ball valve body 53 ensures that only when the first ball valve body 53 is in the open state, the gas inside the exhaust duct 1 can smoothly pass through the filter cartridge 11 for efficient filtration, thereby greatly improving the operating efficiency and user experience of the overall system.

[0040] The device further limits the number of teeth of the first main irregular gear 56, the first sub-transmission gear 55, the second main irregular gear 65 and the second sub-transmission gear 66. The number of teeth of the first main irregular gear 56 and the second main irregular gear 65 is precisely adjusted to one-fourth of the number of teeth of the first sub-transmission gear 55 and the second sub-transmission gear 66. This design ensures that the first main irregular gear 56 and the second main irregular gear 65 can maintain perfect synchronous operation, and also ensures that the first sub-transmission gear 55 and the second sub-transmission gear 66 can be effectively triggered at the same time, thereby greatly enhancing the overall use effect.

[0041] In one embodiment of the present invention, Figure 7 As shown, the gas measuring seat 8 includes a lower test seat body 81, an air volume sensor 82 and a second valve-type one-way exhaust valve 83, wherein the lower test seat body 81 is fixedly connected to the bottom of the exhaust duct 1 and is communicated with the inside of the exhaust duct 1, the lower test seat body 81 is located outside the first frame 51, the air volume sensor 82 and the second valve-type one-way exhaust valve 83 are arranged on the upper and lower inner walls of the lower test seat body 81, and the air volume sensor 82 is connected to the controller 12 through a bus system to realize data transmission and reception of control instructions.

[0042] Specifically, the structure and connection relationship of the gas measuring seat 8 are further explained. The component cleverly integrates the lower test seat body 81, the air volume sensor 82 and the second valve-type one-way exhaust valve 83, wherein the lower test seat body 81 is carefully placed on the outside of the first frame body 51. This layout ensures that when the central air conditioner is started, the air can smoothly flow into the internal space of the lower test seat body 81 first, and then the air will flow through the air volume sensor 82, which can keenly capture the slight changes in air flow and convert them into accurate data signals. Then, the detected air will pass through the second valve-type one-way exhaust valve 83, which ensures the one-way flow of gas and effectively prevents backflow, and finally discharges the air from the lower test seat body 81. The design of the second valve-type one-way exhaust valve 83 also effectively prevents dust and impurities from entering the exhaust duct 1, ensuring that the exhaust duct 1 is clean and tidy and has a good use effect.

[0043] In one embodiment of the present invention, Figure 8As shown, the air intake mechanism 9 includes a bracket 91, an air distribution pipe 92, a first interface 93, a second interface 94, an annular seat 95, a first air hole 96 and a second air hole 97, wherein the bracket 91 is fixedly connected to the bottom of the exhaust duct 1 and corresponds to the position of the first frame 51, the air distribution pipe 92 is fixedly connected to the inner wall of the bracket 91, the first interface 93 and the second interface 94 are respectively arranged at the bottom of the air distribution pipe 92, the first interface 93 and the second interface 94 are respectively connected to the external high-temperature steam pipeline and the high-temperature gas pipeline, the annular seat 95 is arranged on the top of the air distribution pipe 92, and is sleeved on the outside of the air intake disk 59, the inner wall of the annular seat 95 is slidably connected to the surface of the air intake disk 59, the first air hole 96 and the second air hole 97 are respectively opened on the inner wall of the annular seat 95, and correspond to the positions of the two groups of air intake holes 510, and two groups of air transmission channels are arranged inside the air distribution pipe 92, and the first interface 93 and the second interface 94 are respectively connected to the inside of the first air hole 96 and the second air hole 97 through the two groups of air transmission channels.

[0044] It should be noted that the external high-temperature steam pipeline, high-temperature gas pipeline and gas transmission channel described in this embodiment are not shown in the figure. The external high-temperature steam pipeline and the high-temperature gas pipeline have a set pressure inside, so that when the first air hole 96 is connected with one group of air inlet holes 510 or the second air hole 97 is connected with another group of air inlet holes 510, the high-temperature steam inside the external high-temperature steam pipeline or the high-temperature gas inside the high-temperature gas pipeline can be automatically and continuously injected into the air inlet hole 510.

[0045] Specifically, the structure and connection relationship of the air intake mechanism 9 are further described. When the first air hole 96 is precisely aligned with and connected to a certain group of air intake holes 510, or the second air hole 97 is precisely aligned with and connected to another group of air intake holes 510, the medium (i.e., high-temperature steam or high-temperature gas) in the external high-temperature steam pipe or high-temperature gas pipe will automatically flow into the corresponding air intake hole 510 by utilizing the pressure difference between the inside and outside of the pipe. These media are then smoothly transported to the position of the exhaust hole 58 through a carefully designed gas transmission channel. Finally, the medium is discharged from the exhaust hole 58 and enters the exhaust duct 1, completing the task of high-temperature steam sterilization or high-temperature gas drying, wherein, The air delivery channel is cleverly arranged inside the second ball valve body 54, its central axis and the air inlet disk 59. It is worth mentioning that by rotating the air inlet disk 59, the user can easily change the position of the air inlet hole 510 to adapt to different work requirements. However, it should be noted that in order to ensure the normal operation of the system, the two groups of air inlet holes 510 cannot be in a connected state at the same time when in use. That is to say, when the first air hole 96 is connected to one group of air inlet holes 510, the second air hole 97 must remain disconnected from the other group of corresponding air inlet holes 510, and vice versa. Such a design not only ensures the smooth flow of the medium, but also avoids possible interference and conflict, and has a good use effect.

[0046] In summary, a central air-conditioning air outlet duct purification and sterilization device in an embodiment of the present invention has a reasonable structure and an intelligent monitoring function. It can automatically detect the operating status of the central air-conditioning and automatically start the high-temperature sterilization device when the customer finishes using it or during the preset night time period to effectively sterilize the inside of the exhaust duct 1. During the sterilization process, the present invention can also flexibly adjust the positions of the ultraviolet sterilization lamp 10 and the filter cartridge 11 to effectively prevent high-temperature steam and gas from damaging the ultraviolet sterilization lamp 10 and the filter cartridge 11. Its highly automated characteristics not only eliminate the need for manual supervision, but also greatly improve work efficiency, reduce labor intensity, and show excellent use results.
