[0002] In many scenarios, such as industrial production and warehousing, timely detection of carbon dioxide leaks is necessary. A carbon dioxide detector is a specialized device used to measure atmospheric carbon dioxide levels and other related parameters. This device typically incorporates a carbon dioxide sensor component, also known as a detection probe.

[0003] During use, the detection probe of the existing carbon dioxide leak detector is easily contaminated by dust, impurities, etc., which affects the accuracy and reliability of the detection. It requires regular manual cleaning, which is relatively cumbersome. Summary of the Invention

Driven by the reciprocating component, the air blowing component sucks external air into the interior and transmits the gas to a position close to the detector through the guide component.

[0005] Furthermore, the circulation mechanism further includes: A conical member, the conical member is arranged at the top of the curved rod, the outer wall of the curved rod is slidably connected to the inner wall of the guide assembly, the bottom diameter of the conical member is smaller and the top diameter is larger; The limiting plate is arranged on the top of the conical member.

[0006] Furthermore, the detector comprises: An instrument body, the bottom of which is connected to the top of the box; A detection head, the detection head is arranged on the inner wall of the box; An alarm is mounted on the top of the instrument body.

[0007] Furthermore, the cleaning mechanism includes: The gear ring, the top of which is slidably connected to the top of the inner wall of the box, is sleeved on the top of the detection head. The worker pulls the rack to engage the rack with the gear ring, thereby rotating the gear ring and driving the bristles on the curved plate to clean the detection head; The outer wall of the rack is meshed with the outer wall of the gear ring, and a sleeve is provided on the side of the outer wall of the box body close to the rack.

[0008] Furthermore, the cleaning mechanism further comprises: An arc-shaped plate, the top of which is rotatably connected to the bottom of the gear ring, the outer wall of which is provided with a magnetic block, and the inner wall of which is provided with a soft brush; The pull rod is in contact with the magnetic block. The pull rod is made of metal. The outer wall of the pull rod is slidably connected to the inner wall of the box. The pull rod pulls up the arc plate through magnetic attraction and keeps it away from the detection head during detection.

[0009] Furthermore, the reciprocating assembly includes: A driving rod, the outer wall of which is connected to the motor, and the end of the driving rod away from the motor is rotatably connected to a connecting rod. The driving rod rotates, causing the connecting rod to drive the limiting rod to slide up and down in the groove in the branch rod, thereby driving the air blowing assembly to move up and down, providing a power source for the air sucking assembly. The motor is set to work in stages; A limiting rod, the limiting rod being arranged at one end of the driving rod away from the connecting rod, the other end of the limiting rod being connected to the outer wall of the air blowing assembly; The support rod is symmetrically arranged on the inner wall of the box body, and the inner wall of the support rod is slidably connected to the outer wall of the limiting rod.

[0010] Furthermore, the air blowing assembly includes: The bottom shell has an outer wall connected to the outer wall of the limiting rod, an air extraction hole is symmetrically opened at the bottom of the bottom shell, a groove is opened on the inner wall of the bottom shell close to the air extraction hole, and the bottom of the guide component contacts the inner wall of the groove.

[0011] Furthermore, the air blowing assembly further comprises: a folding cylinder, the folding cylinder being mounted on the top of the bottom shell; A top shell is mounted on the top of the folding cylinder, and air outlet holes are evenly opened on the top of the top shell; A rubber sheet is arranged on the top of the top shell. The position of the rubber sheet corresponds to the position of the air outlet. A small hole is provided in the middle of the rubber sheet. When relaxed, the small hole is closed due to the tension and elasticity of the rubber sheet itself. When the guide component overlaps with the air blowing component and is squeezed upward, the air pressure in the cylinder increases, causing the gas to impact the rubber sheet, opening the small hole and causing the air flow to flow out of the small hole to purge the bottom of the detection head.

[0012] Furthermore, the flow guide assembly includes: a disc, the disc being arranged on the inner wall of the groove; A counterweight block is mounted on the top of the disc, the middle portion of the counterweight block is sleeved with the outer wall of the curved rod, and a protrusion is provided on one side of the counterweight block, which engages with a slide groove on the curved rod; An elastic rod, symmetrically arranged on the inner wall of the counterweight, and having relatively low elasticity; An extrusion ring is installed at one end of the elastic rod close to the bent rod. The outer wall of the extrusion ring contacts the outer wall of the bent rod. The extrusion ring has a small friction force and produces a small friction with the surface of the conical part. After the disc is separated from the bottom shell, due to the small friction force, under the action of the gravity of the counterweight block, the extrusion ring gradually slides downward and drops the disc onto the groove again.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention provides a circulation mechanism so that the air flow is blown out from the top of the air blowing assembly and contacts the detection head. The air in the box is circulated through multiple reciprocating motions, so that the air around the detection head is affected by the air flow, is pumped into the box and then discharged, which is beneficial for the detection head to detect the carbon dioxide concentration in the surrounding air. At the same time, it can also reduce the contact between the detection head and dust in the air, thereby extending the cleaning cycle.

[0014] 2. The present invention sets a cleaning mechanism. Initially, the pull rod is inserted into the interior of the box, so that the pull rod contacts the magnetic block and is attracted by the magnetic block, and the arc plate is attached to the pull rod and pulled outward, so that the arc plate is away from the detection head. When maintenance is required, the worker pulls out the pull rod so that the arc plate rotates downward by gravity and approaches the detection head. Then the worker pulls the rack to engage the rack with the gear ring, thereby rotating the gear ring, and then driving the bristles on the arc plate to clean the detection head. Then the screen plate is replaced to keep the internal environment of the box clean, extend the cleaning cycle of the equipment, and simplify the operation of the worker cleaning the probe.

[0015] 3. The present invention sets an air blowing assembly, and the bottom shell unfolds the folding cylinder. At this time, the guide assembly slowly moves downward on the cone, so that the air extraction hole at the bottom of the bottom shell is filled with air. After the guide assembly moves downward to block the air extraction hole, the reciprocating assembly drives the bottom shell to move upward again. At this time, a relatively sealed state is formed in the cylinder, and the gas is finally blown out from the air outlet at the top, so that the detection head detects the outside air, draws in the gas at the bottom of the box and pushes it upward, so that the detection head quickly contacts the gas below the equipment for detection, thereby expanding the detection range of the detector.

[0016] 4. The present invention sets a guide component to create a gap between the exhaust hole and the disc for a period of time, which facilitates the air at the bottom to enter the interior of the bottom shell, and the counterweight block will gradually move downward, eventually causing the disc to overlap with the interior of the groove again. At this time, the bottom of the bottom shell is sealed again to form a closed space. As the reciprocating component moves upward, the gas is eventually blown upward, ensuring that the gas is drawn in from below and blown out from above, and the air under the equipment is transferred to a position close to the detection head, which can reduce the time it takes for carbon dioxide to leak and be discovered, expand the application scenarios of the equipment, and improve safety.

DETAILED DESCRIPTION

[0019] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications. Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a self-cleaning carbon dioxide leak detector is described as follows.

[0020] It comprises: a box body 1, a sieve plate 3 is provided at the bottom of the box body 1; Motor 2, motor 2 is symmetrically arranged on both sides of the box 1; The detector 6 is installed on the top of the box 1, and its bottom extends into the interior of the box 1; The circulation mechanism 4 is arranged on the inner wall of the box body 1; The cleaning mechanism 5 is installed on the top of the inner wall of the box body 1 near the detector 6.

[0021] During operation, the staff installs the detector 6 and the box 1 on the wall of the part that needs to be detected, so that the detector 6 is above the box 1 and fixed to the wall. When detection is required, the motor 2 drives the circulation mechanism 4 to convert the airflow, so that the external air enters the box 1, so that the detector 6 can detect the carbon dioxide concentration in the surrounding air environment. A sieve plate 3 is provided at the bottom of the box 1. When the air enters the box 1, it is filtered by the sieve plate 3 to protect the detection head 603 at the bottom of the detector 6 to prevent dust in the air from adhering to the detection head 603 and affecting the detection sensitivity. When cleaning is required, the staff manually drives the cleaning mechanism 5 to clean the surface of the detection head 603.

[0022] The circulation mechanism 4 includes: a curved rod 401, the bottom of which is mounted on the inner wall of the housing 1, and a sliding groove 407 is formed on the surface of the curved rod 401; a reciprocating assembly 402, which is symmetrically arranged on the inner wall of the housing 1, and the outer wall of the reciprocating assembly 402 is connected to the motor 2; and a flow guide assembly 404, which is arranged on the inner wall of the air blowing assembly 403 and moves along the curved rod 401. The air blowing assembly 403 is installed on the outer wall of the reciprocating assembly 402. Driven by the reciprocating assembly 402, the air blowing assembly 403 draws external air into the interior and transmits the gas to a position close to the detector 6 through the guide assembly 404; The circulation mechanism 4 also includes: a conical member 405, which is arranged at the top of the bent rod 401, the bottom diameter of the conical member 405 is smaller, and the top diameter is larger, and the outer wall of the bent rod 401 is slidingly connected to the inner wall of the guide component 404; a limiting plate 406, which is arranged at the top of the conical member 405.

[0023] During the inspection process, the motor 2 drives the reciprocating component 402 to enable the air blowing component 403 to move up and down. When the air blowing component 403 drives the guide component 404 to move upward along the curved rod 401, the middle of the guide component 404 gradually contacts the surface of the conical member 405 on the curved rod 401 and gradually tightens. Then the reciprocating component 402 drives the air blowing component 403 to descend. At this time, the guide component 404 is separated from the air blowing component 403, and is slowly lowered on the surface of the conical member 405, so that the air blowing component 403 can pass in. When the guide component 404 drops to overlap with the blower component 403, the reciprocating component 402 pushes upward again, so that the air flow is blown out from the top of the blower component 403 and contacts the detection head 603. Through multiple reciprocating motions, the air in the box 1 is circulated, so that the air around the detection head 603 is affected by the air flow, is pumped into the inside of the box 1 and then discharged, which is beneficial for the detection head 603 to detect the carbon dioxide concentration in the surrounding air. At the same time, it can also reduce the contact of the detection head 603 with dust in the air and extend the cleaning cycle.

[0024] The detector 6 includes: an instrument body 601 , the bottom of which is connected to the top of the box 1 ; a detection head 603 , which is arranged on the inner wall of the box 1 ; and an alarm 602 , which is installed on the top of the instrument body 601 .

[0025] The cleaning mechanism 5 includes: a gear ring 501, the top of the gear ring 501 is slidably connected to the top of the inner wall of the box body 1, and the gear ring 501 is sleeved on the top of the detection head 603; a rack 502, the outer wall of the rack 502 is meshed and connected with the outer wall of the gear ring 501, and a shell 503 is provided on the side of the outer wall of the box body 1 close to the rack 502.

[0026] The cleaning mechanism 5 also includes: an arc-shaped plate 504, the top of the arc-shaped plate 504 is rotatably connected to the bottom of the gear ring 501, and bristles are provided on the inner side of the arc-shaped plate 504, which brush the dust on its surface when in contact with the detection head 603. The bristles are made of flexible material. The arc-shaped plate 504 is rotatably installed on the gear ring 501, and the maximum angle when rotating along the pin is vertical, and the detection head 603 can no longer be detected to avoid damage. The outer wall of the arc-shaped plate 504 is provided with a magnetic block 505; a pull rod 506, the pull rod 506 is in contact with the magnetic block 505, the pull rod 506 is made of metal, and the outer wall of the pull rod 506 is slidably connected to the inner wall of the box body 1. The pull rod 506 pulls up the arc-shaped plate 504 by magnetic attraction, and keeps it away from detection during detection.

[0027] After the detector 6 has been used for a long time, the dust on the detection head 603 gradually increases. At this time, it is no longer possible to completely remove the dust by blowing alone, and manual intervention is required. Initially, the pull rod 506 is inserted into the box body 1, so that the pull rod 506 contacts the magnetic block 505. Attracted by the magnetic block 505, the curved plate 504 is attached to the pull rod 506 and pulled outward, so that the curved plate 504 is away from the detection head 603. When maintenance is required, the worker pulls out the pull rod 506, so that the curved plate 504 rotates downward by gravity. Close to the detection head 603, the curved plate 504 is rotatably installed on the gear ring 501, and the maximum angle when rotating along the pin is vertical, and the detection head 603 can no longer be detected to avoid damage. The worker then pulls the rack 502 to engage the rack 502 with the gear ring 501, thereby rotating the gear ring 501, and then drives the bristles on the curved plate 504 to clean the detection head 603, and then replaces the screen plate 3 to keep the internal environment of the box 1 clean, extend the cleaning cycle of the equipment, and simplify the operation of the worker to clean the probe.

[0028] Example 2, please refer to Figures 1-8The present invention provides a technical solution: on the basis of Example 1, the reciprocating assembly 402 includes: a driving rod 4021, the outer wall of the driving rod 4021 is connected to the motor 2, and the end of the driving rod 4021 away from the motor 2 is rotatably connected to the connecting rod 4022; a limiting rod 4023, the limiting rod 4023 is arranged at the end of the driving rod 4021 away from the connecting rod 4022, and the other end of the limiting rod 4023 is connected to the outer wall of the inflation assembly 403; a support rod 4024, the support rod 4024 is symmetrically arranged on the inner wall of the box body 1, and the inner wall of the support rod 4024 is slidably connected to the outer wall of the limiting rod 4023.

[0029] During the test, the motor 2 drives the driving rod 4021 to rotate, so that the connecting rod 4022 drives the limiting rod 4023 to slide up and down in the groove in the branch rod, thereby driving the air blowing component 403 to move up and down, providing a power source for the air sucking component 403. The motor 2 is set to work in stages. Compared with the use of a blower, it can reduce energy consumption, and the structure is simpler and easy to install and use at high places. The air blowing assembly 403 includes: a bottom shell 4031, the outer wall of the bottom shell 4031 is connected to the outer wall of the limit rod 4023, the bottom of the bottom shell 4031 is symmetrically provided with an air extraction hole 4032, the inner wall of the bottom shell 4031 is provided with a groove 4033 on one side close to the air extraction hole 4032, and the bottom of the guide assembly 404 is in contact with the inner wall of the groove 4033 The air blowing component 403 also includes: a folding cylinder 4034, which is installed on the top of the bottom shell 4031; a top shell 4035, which is installed on the top of the folding cylinder 4034, and air outlet holes 4037 are evenly opened on the top of the top shell 4035; a rubber sheet 4036, which is arranged on the top of the top shell 4035, and the position of the rubber sheet 4036 corresponds to the position of the air outlet holes 4037. A small hole is provided in the middle of the rubber sheet 4036. When relaxed, the small hole is in a closed state due to the tension and elasticity of the rubber sheet 4036 itself. When the guide component 404 overlaps with the air blowing component 403 and is squeezed upward, the air pressure in the cylinder increases, causing the gas to impact the rubber sheet 4036, thereby opening the small hole and causing the air flow to flow out from the small hole to purge the bottom of the detection head 603.

[0030] At the beginning, the bottom shell 4031 is driven by the motor 2 to approach the top shell 4035. During operation, the reciprocating assembly 402 drives the bottom shell 4031 to move downward, so that the bottom shell 4031 unfolds the folding cylinder 4034. At this time, the guide assembly 404 slowly moves downward on the cone 405, so that the air extraction hole 4032 at the bottom of the bottom shell 4031 is filled with air. Until the guide assembly 404 moves downward to block the air extraction hole 4032, the reciprocating assembly 402 drives the bottom shell 4031 to move upward again. At this time, A relatively sealed state is formed in the cylinder, and the gas is finally blown out from the air outlet 4037 at the top, so that the detection head 603 detects the outside air. After the gas in the cylinder is blown out, the above steps are repeated again, and the bottom shell 4031 continues to move downward, and the guide component 404 blocks the air extraction hole 4032 and then moves upward again. After repeating several times and detecting no abnormalities, it can be stopped. After a while, it is opened again, and the gas at the bottom of the box body 1 is sucked in and pushed upward, so that the detection head 603 quickly contacts the gas below the equipment for detection; Since the density of carbon dioxide is greater than that of air, carbon dioxide leaks usually occur in the lower layer of the space. When the equipment is installed at a higher position, it is not convenient to quickly detect the air at the bottom, resulting in the gas leakage being discovered only after a certain period of time, shortening the repair time of the staff and causing greater harm. The above problems can be effectively avoided by setting the air blowing component 403.

[0031] The flow guide assembly 404 includes: a disc 4041, which is arranged on the inner wall of the groove 4033; a counterweight block 4042, which is installed on the top of the disc 4041, and the middle part of the counterweight block 4042 is connected to the outer wall of the curved rod 401. A protrusion 4045 is provided on one side of the counterweight block 4042, and the protrusion 4045 engages with the slide groove 407 on the curved rod 401; an elastic rod 4043, which is symmetrically arranged on the inner wall of the counterweight block 4042; an extrusion ring 4044, The extrusion ring 4044 is mounted on the end of the elastic rod 4043 close to the curved rod 401. The outer wall of the extrusion ring 4044 contacts the outer wall of the curved rod 401. The extrusion ring 4044 has a small friction force. The elastic rod 4043 has a small elasticity, which produces a small friction with the surface of the conical member 405. After the disc 4041 is separated from the bottom shell 4031, due to the small friction force, the extrusion ring 4044 gradually slides downward under the action of the weight of the counterweight 4042, and the disc 4041 falls back into the groove 4033. When the reciprocating assembly 402 drives the bottom shell 4031 to move upward, the disc 4041 is stuck in the groove 4033 of the bottom shell 4031 and moves upward. Since the diameter of the conical member 405 increases gradually, as the counterweight 4042 moves upward, the elastic rod 4043 and the extrusion ring 4044 are gradually subjected to a greater extrusion force. Therefore, during the downward movement of the bottom shell 4031, the counterweight 4042 cannot quickly follow its downward movement, resulting in a gap between the air extraction hole 4032 and the disc 4041 for a period of time. , which makes it easier for the air at the bottom to enter the bottom shell 4031, and the counterweight block 4042 will gradually move downward, eventually making the disc 4041 overlap with the inside of the groove 4033 again. At this time, the bottom of the bottom shell 4031 is sealed again to form a closed space. As the reciprocating component 402 moves upward, the gas will eventually be blown upward, ensuring that the gas is drawn in from the bottom and blown out from the top, and the air under the equipment is transferred to a position close to the detection head 603, which can reduce the time it takes for carbon dioxide to leak and be discovered, expand the application scenarios of the equipment, and improve safety.

[0032] The specific workflow is as follows: During operation, the staff installs the detector 6 and the box 1 on the wall of the part that needs to be tested, so that the detector 6 is above the box 1 and fixed to the wall. During the testing process, the motor 2 drives the reciprocating component 402 to enable the air blowing component 403 to move up and down. When the air blowing component 403 drives the guide component 404 to move upward along the curved rod 401, the middle of the guide component 404 gradually contacts the surface of the cone 405 on the curved rod 401 and gradually tightens. Then the reciprocating component 402 drives the air blowing component 403 to descend. At this time, the guide component 404 is separated from the air blowing component 403, and is slowly lowered on the surface of the cone 405, so that the air blowing component 403 can Air is introduced. When the guide component 404 drops to overlap with the air blowing component 403, the reciprocating component 402 pushes upward again, so that the air flow is blown out from the top of the air blowing component 403 and contacts the detection head 603. The air in the box 1 is circulated through multiple reciprocating motions, so that the air around the detection head 603 is affected by the air flow, is pumped into the inside of the box 1 and then discharged to facilitate the detector 6 to detect the carbon dioxide concentration in the surrounding air environment. A sieve plate 3 is provided at the bottom of the box 1. When the air enters the box 1, it is filtered by the sieve plate 3 to protect the detection head 603 at the bottom of the detector 6, so as to prevent dust in the air from adhering to the detection head 603 and affecting the detection sensitivity. When cleaning is required, the worker pulls out the pull rod 506, causing the arc plate 504 to rotate downward by gravity, close to the detection head 603. The arc plate 504 is rotatably installed on the gear ring 501, and the maximum angle when rotating along the pin is vertical, and the detection head 603 can no longer be detected to avoid damage. The worker then pulls the rack 502 to engage the rack 502 with the gear ring 501, thereby rotating the gear ring 501, and then drives the bristles on the arc plate 504 to clean the detection head 603, and then replaces the screen plate 3 to keep the internal environment of the box 1 clean.
