And as users' requirements for air quality increase, more and more air conditioners begin to use carbon dioxide (CO2) sensors. Specifically, the carbon dioxide sensor detects the concentration of carbon dioxide in the air and sends it to the controller, so that the controller controls the display light to light up according to the concentration of carbon dioxide, thereby prompting the user, and the user can manually adjust the air conditioner to improve the air quality.

[0003] Chinese patent CN103063809A authorized and announced on April 24, 2013 discloses a carbon dioxide detection device and detection method for life detection in ruins, which includes a rod sleeve: the rod sleeve is a hollow cylindrical structure, the conical head is fixed to the front end of the internal bracket to form a sampling core, the rear end of the conical sleeve is sealed and connected to the front end of the sampling rod sleeve to form a hollow sampling rod, the sampling core is inserted into the sampling rod and can be slidably arranged and is provided with a locking device; the gas sampling pump, the carbon dioxide sensor and the partition are all fixed on the internal bracket, the partition separates the gas sampling pump and the carbon dioxide sensor, and is slidably sealed with the inner wall of the sampling rod. In the above application documents, the device is in an overly long form under normal circumstances, making it inconvenient to carry. At the same time, during the downward movement of the detection ruins, the device at the bottom may collide with objects in the ruins, causing damage, and there are certain limitations on the downward extension distance. Summary of the invention

[0004] In order to solve the problems in the prior art that the equipment is normally too long, making it inconvenient to carry, and that during the downward movement of the detection ruins, the device at the bottom may collide with objects in the ruins and cause damage, and that there are certain limitations on the downward extension distance, the present invention proposes a detection device for electronic-grade carbon dioxide, which can perform detection according to different heights selected by people.

[0005] A detection device for electronic grade carbon dioxide, comprising a carbon dioxide detector and a working plate;

[0006] An extension device is installed on the surface of the working plate, and the extension device includes a limiting hole and a turntable. A chain is installed inside the limiting hole, the top of the chain is wrapped around the inside of the turntable, and the bottom of the chain is hinged with a chassis. Pressure bins are penetrated and fixedly connected inside the two sides of the chain, and an isolation plate is fixedly connected inside the pressure bin. A first chamber is installed on the left side of the isolation plate, and a second chamber is installed on the right side of the isolation plate. A pressure rod is slidably connected inside the first chamber, and an insertion block is slidably connected inside the second chamber. A card slot is inserted into the bottom surface of the insertion block, and the surface of the card slot is fixedly connected to the top surfaces on both sides of the chain. A baffle is installed on the side surface of the pressure rod away from the pressure bin, and an end of the baffle away from the pressure rod is hinged with a support block, and the top of the baffle is hinged with a directional telescopic rod.

[0007] Furthermore, a filtering device is provided inside the chassis, and the filtering device includes a filter net, the surface of the filter net is fixedly connected to the inside of the chassis, the bottom of the filter net is rotatably connected to fan blades, the surface of the chassis is hinged with a hinge and a protective net, and a soft rubber tape is installed between the inside of the chassis and the air pipe.

[0008] Furthermore, the chain includes a plurality of cylinders, and the plurality of cylinders are connected in series by a hinge rod, and the extension and retraction of the chain are achieved by allowing relative rotation between the chain links. When it is necessary to adjust the length of the chain or change its shape, relative movement can be generated between the chain links by controlling the rotation of the hinge rod, thereby achieving an overall change of the chain.

[0009] Furthermore, the surface of the turntable is fixedly connected to the side of the working plate, one end of the turntable is rotatably connected to the turntable, and the other end of the turntable is penetrated and fixedly connected to the exhaust component, which can be conveniently connected to an external pipeline or other equipment to realize gas extraction and transmission. The rotation function of the turntable can also be used to adjust the relative position of the exhaust component and the surrounding environment to better perform gas extraction work.

[0010] Furthermore, the top of the vacuum assembly is fixedly connected to the bottom of the working plate, and the vacuum assembly and the carbon dioxide detector are assembled and connected with each other, so that the vacuum assembly can stably and effectively extract gas samples and transmit them to the carbon dioxide detector for detection, thereby ensuring the accuracy and real-time performance of carbon dioxide detection.

[0011] Furthermore, the pressing bin and the card slot are both assembled inside each cylinder of the chain, realizing the extension, locking and retraction functions of the chain, which ensures the stability and reliability of the chain during the extension and retraction process.

[0012] Furthermore, an air pipe is installed on the central surface of the chain, a positioning block is fixedly connected to the surface of the air pipe, and the surface of the positioning block is fixedly connected to the inner wall of the chain. The chain not only bears the weight of the chassis and controls its extension and retraction, but also achieves communication with the air extraction component through the air pipe installed at its center to provide a gas sample for the carbon dioxide detector. The positioning block ensures the stability and reliability of this gas transmission channel.

[0013] Furthermore, the surface of the air extraction component penetrates the turntable and is interconnected with the air pipe, and the air extraction component and the air pipe are mutually interconnected.

[0014] Furthermore, the tops of the directional telescopic rod and the support block are respectively fixedly connected to the bottom surface of the working plate. Through the stability and reliability of the directional telescopic rod, it can provide necessary support and guidance when the chain is extended or retracted. As the chain is extended or retracted, the baffle will move accordingly, and the directional telescopic rod will adapt to this movement through its telescopic function, ensuring that the baffle always maintains the correct relative position with the pressure rod.

[0015] Furthermore, the protective net is assembled in three groups and wrapped around the chassis. The main function of the protective net is to protect the chassis and its internal equipment from the intrusion of the external environment. At the same time, the protective net can also provide a certain safety protection effect to prevent accidents when people or objects come into direct contact with the chassis.

[0016] The difference from the prior art is that the beneficial effects of this application are:

[0017] (1) The detection device for electronic-grade carbon dioxide drives the turntable by extending the turntable in the device, thereby releasing and retracting the chain. At the same time, the chain extends downward through the limit hole to drive the chassis to the required position. The device is composed of a plurality of cylinders connected by hinges, so that the cylinders can be flexibly extended and bent to provide a stable and reliable effect for carbon dioxide detection.

[0018] (2) The detection device for electronic grade carbon dioxide comprises a filter screen and a fan blade in the filtering device. The filter screen is fixed inside the chassis, and the fan blade is located below the filter screen and can rotate. The periphery of the chassis is covered with three layers of protective nets to achieve the protective effect of the protective nets to prevent the chassis from being damaged during the descent process.

[0037] Embodiment 1

[0038] See also Figure 1-Figure 7 , as shown in the figure, a detection device for electronic grade carbon dioxide includes a carbon dioxide detector 100 and a working plate 200;

[0039] An extension device 400 is installed on the surface of the working plate 200. The extension device 400 includes a limit hole 406 and a turntable 417. The limit hole 406 is equipped with a chain 401. The top of the chain 401 is wound around the inside of the turntable 417. The chain 401 includes a plurality of cylinders, and the plurality of cylinders are connected in series through a hinge rod. By allowing relative rotation between the links, the extension and retraction of the chain 401 are achieved. When it is necessary to adjust the length of the chain 401 or change its shape, the relative movement between the links can be controlled by controlling the rotation of the hinge rod, thereby achieving the overall change of the chain 401. The bottom of the chain 401 is hinged with a chassis 416. The surface of the disk 417 is fixedly connected to the side of the working plate 200, one end of the turntable 417 is rotatably connected to the turntable 418, and the other end of the turntable 417 is connected to the exhaust component 300, which can be easily connected to an external pipeline or other equipment to achieve gas extraction and transmission. The rotation function of the turntable 417 can also be used to adjust the relative position of the exhaust component 300 and the surrounding environment to better perform gas extraction. The top of the exhaust component 300 is fixedly connected to the bottom of the working plate 200, and the exhaust component 300 and the carbon dioxide detector 100 are assembled and connected with each other, so that the exhaust component 300 can be stably and effectively The gas sample is extracted and transmitted to the carbon dioxide detector 100 for detection, thereby ensuring the accuracy and real-time performance of carbon dioxide detection. The two sides of the chain 401 are penetrated and fixedly connected with a pressure chamber 402. The pressure chamber 402 and the card slot 415 are both assembled inside each cylinder of the chain 401, and the extension, locking and retraction functions of the chain 401 are jointly realized, which ensures the stability and reliability of the chain 401 during the extension and retraction process. The interior of the pressure chamber 402 is fixedly connected with an isolation plate 410. The left side of the isolation plate 410 is equipped with a first chamber 412, and the right side of the isolation plate 410 is equipped with a second chamber 411. The chain 40 1 is equipped with an air pipe 408 on the central surface, and a positioning block 409 is fixedly connected to the surface of the air pipe 408. The surface of the positioning block 409 is fixedly connected to the inner wall of the chain 401. The chain 401 not only bears the weight of the chassis 416 and controls its extension and retraction, but also realizes communication with the exhaust component 300 through the air pipe 408 installed in the center, so as to provide a gas sample for the carbon dioxide detector 100. The positioning block 409 ensures the stability and reliability of this gas transmission channel. The surface of the exhaust component 300 passes through the turntable 417 and is mutually connected with the air pipe 408, and mutually connected with the air pipe 408 is realized through the exhaust component 300.This means that the air sample extracted from the vicinity of the chassis 416 can be directly transmitted to the exhaust assembly 300 through the air pipe 408 for subsequent carbon dioxide detection. The first chamber 412 is internally slidably connected to a pressure rod 413, and the second chamber 411 is internally slidably connected to an insert block 414. The bottom surface of the insert block 414 is inserted with a card slot 415. The surface of the card slot 415 is fixedly connected to the internal top surface on both sides of the chain 401. The pressure rod 413 is equipped with a baffle 404 on the side surface away from the pressure bin 402. The end of the baffle 404 away from the pressure rod 413 is hinged. There is a support block 403, and the top of the baffle 404 is hinged with a directional telescopic rod 405. The directional telescopic rod 405 and the top of the support block 403 are respectively fixedly connected to the bottom surface of the working plate 200. Through the stability and reliability of the directional telescopic rod 405, it can provide necessary support and guidance when the chain 401 is extended or retracted. As the chain 401 is extended or retracted, the baffle 404 will move accordingly, and the directional telescopic rod 405 will adapt to this movement through its telescopic function, ensuring that the baffle 404 always maintains a correct relative position with the pressure rod 413.

[0040] When in use, people first place the carbon dioxide detector 100 on the working plate 200 and align the chassis 416 with the desired position. By turning the rotating plate 418, the chain 401 inside the rotating plate 417 begins to stretch, just like opening a tape measure, driving the chassis 416 to gradually descend. The cylinder of the chain 401 allows it to bend and stretch flexibly. When the chain 401 descends, it will pass through the limiting hole 406. At this time, the pressure rod 413 next to the chain 401 will hit the baffle 404, and the baffle 404 will push the pressure rod 413 upward, which causes the air pressure in the first chamber 412 to increase, thereby pushing the plug 414 in the second chamber 411 to move downward and insert it into the slot 415 next to the chain 401. In this way, each cylinder of the chain 401 is fixed to form a whole to prevent the chassis 416 from shaking when it descends. Once the chassis 416 reaches the specified position, the exhaust assembly 300 starts working. The air is drawn through the air pipe 408, and after passing through the filter device 500 inside the chassis 416, the clean air enters the carbon dioxide detector 100 for accurate carbon dioxide content detection. When people want to retract the chassis 416, they only need to rotate the rotating plate 418 in the opposite direction, which will cause the turntable 417 to start retracting the chain 401. During the retraction process, the pressure rod 413 contacts the baffle 404 again, but this time the baffle 404 will push the pressure rod 413 downward, and the air pressure in the first chamber 412 is reduced, causing the plug 414 in the second chamber 411 to be pulled out of the slot 415. In this way, the chain 401 can bend freely and be completely retracted by the turntable 417. The baffle 404 is fixed to the working plate 200 by the support block 403, and a directional telescopic rod 405 is connected to the top to ensure that the baffle 404 can maintain the correct position when the chain 401 is extended or retracted, and work in conjunction with the pressure rod 413.

[0041] At the same time, in order to reduce the impurities in the air from entering the interior during the work of exhaust, please refer to Figure 1-Figure 7 As shown in the figure, a filter device 500 is arranged inside the chassis 416, and the filter device 500 includes a filter screen 501. The surface of the filter screen 501 is fixedly connected to the inside of the chassis 416, and the bottom of the filter screen 501 is rotatably connected to the fan blade 502. The surface of the chassis 416 is hinged with a hinge and a protective net 503. The protective net 503 is assembled in three groups and wrapped around the chassis 416. The main function of the protective net 503 is to protect the chassis 416 and its internal equipment from the intrusion of the external environment. At the same time, the protective net 503 can also provide a certain safety protection effect to prevent accidents when people or objects directly contact the chassis 416. A soft adhesive tape 505 is installed between the inside of the chassis 416 and the trachea 408.

[0042] When the chassis 416 needs to be placed at a designated location for carbon dioxide detection, the operator will first operate the chassis 416 to descend. At this time, the protective net 503 can protect the internal structure of the chassis 416. When the chassis 416 reaches the designated location, the air extraction component 300 is started to extract the surrounding air through the air pipe 408. The air pipe 408 and the chassis 416 are tightly connected by the soft adhesive tape 505 to ensure that the air can smoothly enter the interior of the chassis 416. During the air extraction process, the fan blades 502 inside the chassis 416 will automatically rotate. , like an automatic small windmill, it blocks large dust and impurities in the air outside the filter 501, and the filter 501 is responsible for further filtering out smaller dust and impurities, ensuring that the air entering the chassis 416 is very clean. The filtered clean air will then enter the carbon dioxide detector 100, so that the detector can more accurately measure the carbon dioxide content in the air. During the whole process, the chassis 416 and its filter device 500 ensure the accuracy of the detection and the protection of the equipment, making the detection of carbon dioxide more reliable and effective.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
