Description

Technical Field

[0001] The invention relates to the technical field of gas detection, and in particular to a household gas detector based on infrared detection. Background Art

[0002] Point-type gas detectors (LED type) are used to detect the leakage concentration of combustible gases, toxic and harmful gases, oxygen and carbon dioxide. The main detection principles include electrochemistry, infrared, catalytic combustion, thermal conductivity and PID photoionization. When the concentration of the measured gas exceeds the preset value, the detector will send out an audible and visual alarm signal so that the user can take measures. The sampling method usually adopts a pump-suction type to suck the air around the detector into the detector body for testing its composition.

[0003] When point-type gas detectors are used at home, they are usually installed at the gas pipe in the kitchen or around the gas tank for real-time detection. However, there is the following problem: because the point-type gas detector detects the content of various gases in the kitchen air in real time, when the user is using the kitchen, the fumes generated will be adsorbed on the filter plate under the suction of the detector. Long-term accumulation may affect the efficiency of the gas detector and the detection accuracy of the gas detector. Therefore, the user needs to regularly disassemble and clean the filter plate of the detector. The operation is complicated and easy to forget. Therefore, a gas detector is designed that can automatically clean the oil accumulated on the filter plate regularly to ensure the normal use of the gas detector. Summary of the invention

[0004] In view of the problem that when the gas detector in the prior art detects the gas content in the kitchen air in real time, oil will accumulate on the filter plate, causing the filter plate to be blocked, affecting the sampling quality and measurement accuracy of the detector, a household gas detector based on infrared detection is proposed.

[0005] The present application provides a household gas detector based on infrared detection, the purpose of which is: by setting a liquid outlet component, when cleaning the oil stains on the filter plate, the detergent can be pressed on the surface of the filter plate, and the water inlet element allows water to flow in. At this time, the filter plate is driven by the self-cleaning component to rotate continuously in the water containing the cleaning liquid, so as to clean the oil stains on the surface of the filter plate. The cleaned water with oil stains is collected in the collecting tube in the collecting component, thereby completing the automatic cleaning of the filter plate, and the cleaned sewage is automatically collected for subsequent treatment.

[0006] The technical solution of the present invention is: a household gas detector based on infrared detection, comprising a mounting plate, and a detection unit arranged on the mounting plate, wherein the detection unit comprises a detection component and a cleaning component arranged on the mounting plate;

[0008] A plurality of protrusions are evenly and equidistantly fixedly mounted on the side end of the mounting plate, and mounting holes for mounting are provided on the protrusions. An infrared detector is installed inside the detector body, and the infrared detector is electrically connected to the sound and light alarm.

[0009] Furthermore, the cleaning component includes a supporting plate arranged on the side wall of the lower end of the mounting plate, a slide rail arranged on the side wall below the mounting plate, a slider slidably arranged in the slide rail, a lifting plate arranged at one end of the slider, and an electric telescopic rod arranged on the upper end of the supporting plate, the telescopic end of the electric telescopic rod is fixedly connected to the lower end of the lifting plate, a liquid outlet component is installed at the upper end of the lifting plate, a collecting component is installed at the lower end of the lifting plate, and a self-cleaning component is installed below the connecting port.

[0010] Furthermore, the liquid outlet component includes a matching cylinder arranged on the upper end of the lifting plate, a circular plate arranged on the inner wall of the upper end of the matching cylinder, arc-shaped through grooves evenly and equidistantly opened on the periphery of the circular plate with the center of the circular plate as the axis, a detergent cylinder arranged at the lower end of the circular plate, and a press-type pump head arranged at the upper end of the detergent cylinder, the detergent cylinder is filled with detergent, and the press-type pump head is located above the circular plate.

[0011] Furthermore, the collecting assembly includes a collecting cylinder arranged at the lower end of the lifting plate, a drain pipe arranged at the lower end of the collecting cylinder, and a connecting pipe arranged between the collecting cylinder and the matching cylinder.

[0012] Furthermore, the self-cleaning component includes an air inlet pipe arranged at the connecting port, a mounting ring groove provided on the inner wall of the air inlet pipe, a filter plate slidably arranged in the mounting ring groove, a primary fixed cylinder arranged on the filter plate, a rotating cylinder arranged on the primary fixed cylinder, a secondary fixed cylinder arranged at the upper end of the rotating cylinder, a driving motor arranged on the secondary fixed cylinder, and a rotating rod arranged at the driving end of the driving motor, one end of the rotating rod is fixedly connected to the bottom end of the primary fixed cylinder, and a water inlet element is installed between the side wall of the rotating cylinder and the mounting plate.

[0018] By setting up a self-cleaning component, the driving motor can drive the filter plate to rotate continuously in the water containing detergent, thereby further improving the cleaning efficiency of the filter plate. The centrifugal force generated by the continuous rotation can better clean the oil stains at the lower end of the filter plate, and the water containing the detergent is discharged during the descending process (when the wrapping shell is still wrapping the lower end of the intake pipe). At this time, the connecting pipe continues to take in water, and the filter plate is further cleaned by clean water, thereby ensuring the cleaning efficiency of the filter plate.

[0019] By setting up a collection component, the collection cylinder can recycle and collect dirty water after use, preventing dirty water from splashing when cleaning the filter plate and affecting the surrounding hygiene. The collected dirty water enters the collection cylinder, which is convenient for subsequent collection and treatment of the dirty water, effectively improving the convenience and practicality of the device.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] Example 1, reference Figure 1-Figure 4 , which is the first embodiment of the present invention, provides a household gas detector based on infrared detection, including a mounting plate 1, and also including a detection unit mounted on the mounting plate 1, the detection unit including a detection component and a cleaning component mounted on the mounting plate 1;

[0033] The detection component includes a detector body 2 fixedly mounted on the side wall of the mounting plate 1, a signal block 3 fixedly mounted on the upper end of the detector body 2, an outflow pipe 4 fixedly mounted on the side wall of the signal block 3, an audible and visual alarm 5 fixedly mounted on the end of the signal block 3 away from the outflow pipe 4, a display window 6 fixedly mounted on the detector body 2, a plurality of buttons 7 fixedly mounted on the display window 6, and a connection port 8 fixedly mounted on the lower end of the detector body 2;

[0034] A plurality of protrusions 9 are evenly and equidistantly fixedly mounted on the side end of the mounting plate 1 , and mounting holes for mounting are provided on the protrusions 9 . An infrared detector (not shown) is installed inside the detector body 2 , and the infrared detector is electrically connected to the sound and light alarm 5 .

[0035] Specifically, the detection component is used to detect the content of the detection gas in the air. A pump body (not shown in the figure) is arranged inside the detector body 2. The pump body is used to circulate the air around the detector into the detector body 2, and detect the air through the infrared detector. The pump body sucks the air around the detector through the connection port 8. After the infrared detector completes the detection, it flows out through the outflow pipe 4. The display window 6 will display the detected concentration in real time. When the concentration of the detection gas in the air exceeds the set threshold, the display window 6 transmits a signal to the sound and light alarm 5 through the signal block 3. The sound and light alarm 5 alarms through sound and light source, so that the user can know the gas leakage and exceeding the standard at the first time.

[0036] The mounting plate 1 is used to install the detector body 2 in a designated area. Generally, household gas detectors are installed at the gas pipeline or gas pipe interface in the kitchen. The mounting plate 1 is fixed on the wall or cabinet through nuts and mounting holes to facilitate user installation and disassembly.

[0037] Example 2, reference Figure 4-Figure 9 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the cleaning component includes a supporting plate 10 fixedly mounted on the lower end side wall of the mounting plate 1, a slide rail 11 fixedly mounted on the lower side wall of the mounting plate 1, a slider 12 slidably mounted in the slide rail 11, a lifting plate 13 fixedly mounted at one end of the slider 12, and an electric telescopic rod 14 fixedly mounted on the upper end of the supporting plate 10, the telescopic end of the electric telescopic rod 14 is fixedly connected to the lower end of the lifting plate 13, a liquid outlet component is installed at the upper end of the lifting plate 13, and a self-cleaning component is installed below the connecting port 8.

[0038] The liquid outlet component includes a matching cylinder 15 fixedly mounted on the upper end of the lifting plate 13, a circular plate 16 fixedly mounted on the inner wall of the upper end of the matching cylinder 15, an arc-shaped through groove 17 evenly and equidistantly arranged around the circular plate 16 with the center of the circular plate 16 as the axis, a detergent cylinder 18 fixedly mounted on the lower end of the circular plate 16, and a push-type pump head 19 fixedly mounted on the upper end of the detergent cylinder 18. The detergent cylinder 18 is filled with detergent, and the push-type pump head 19 is located above the circular plate 16.

[0039] Reference Figure 4 and Figure 5The self-cleaning component includes an air inlet pipe 23 fixedly mounted on the connecting port 8, a mounting ring groove provided on the inner wall of the air inlet pipe 23, a filter plate 24 slidably mounted in the mounting ring groove, a primary fixed cylinder 25 fixedly mounted on the filter plate 24, a rotating cylinder 26 rotatably mounted on the primary fixed cylinder 25, a secondary fixed cylinder 27 fixedly mounted on the upper end of the rotating cylinder 26, a driving motor 28 fixedly mounted on the secondary fixed cylinder 27, a rotating rod 29 fixedly mounted on the driving end of the driving motor 28, one end of the rotating rod 29 is fixedly connected to the bottom end of the primary fixed cylinder 25, and a water inlet element is installed between the side wall of the rotating cylinder 26 and the mounting plate 1.

[0040] The water inlet element includes a water tank 30 fixedly mounted on the mounting plate 1, a water supply pipe 31 fixedly mounted on the side wall of the water tank 30, a connecting pipe 32 fixedly mounted between the water tank 30 and the rotating cylinder 26, and a square hole 33 opened on the side wall of the primary fixed cylinder 25. The shape and size of the lower end surface of the air inlet pipe 23 are the same as the shape and size of the arc-shaped through groove 17 on the circular plate 16. A wrapping shell 34 is fixedly mounted on the outer wall of the matching cylinder 15, and the inner wall radius of the wrapping shell 34 is equal to the outer wall radius of the air inlet pipe 23. A controller (not shown) is fixedly mounted on the mounting plate 1, and the controller is electrically connected to the electric telescopic rod 14, and the electric telescopic rod 14 is electrically connected to the drive motor 28 and the water tank 30.

[0041] Specifically, the cleaning component first drives the lifting plate 13 to move upward through the driving end of the electric telescopic rod 14, and during the movement, drives the matching cylinder 15 on the lifting plate 13 to move upward synchronously, so that the matching cylinder 15 and the lower end of the air inlet pipe 23 are in contact and close contact, so that the two cooperate with each other to form a closed space, and in the process of contact and close contact, the lower end of the filter plate 24 and the push-type pump head 19 are in contact with each other and generate a downward pulling force on the push-type pump head 19, so that the push-type pump head 19 will push the cleaning liquid into the air in the process of pressing downward. The detergent in the agent cylinder 18 is squeezed between the filter plate 24 and the circular plate 16. At the same time, because the lower end of the air inlet pipe 23 and the end surface shape and size of the arc-shaped through groove 17 are the same, when the matching cylinder 15 and the air inlet pipe 23 are in close contact with each other, the lower end of the air inlet pipe 23 is blocked at the arc-shaped through groove 17, so that the circular plate 16 is in a closed state. At this time, when the water inlet element flows clean water into between the filter plate 24 and the circular plate 16, it contacts with the detergent to form a liquid, and the formed liquid can clean the oil stains accumulated on the filter plate 24.

[0042] The controller sets a certain time interval in advance. When the detector is used for a period of time, the controller can control the electric telescopic rod 14 to open, and drive the matching cylinder 15 to move upward through the driving end, thereby squeezing the detergent between the circular plate 16 and the filter plate 24, which is convenient for subsequent cleaning work. The water supply pipe 31 is used to replenish the clean water inside the water tank 30. When the electric telescopic rod 14 rises to the maximum height, the electric telescopic rod 14 triggers the water tank 30 and the driving motor 28 to start. A water pump (not shown in the figure) is arranged inside the water tank 30. When the water tank 30 starts, the water pump will also start. At this time, the water pump inputs the clean water inside the water tank 30 into the air inlet pipe 23, and contacts with the detergent at the lower end of the filter plate 24 to form a liquid, so as to better clean the filter plate 24. At the same time, the driving motor 28 drives the rotating rod 29 to rotate through the driving end, and then drives the filter plate 24 to rotate through the primary fixed cylinder 25, so that the filter plate 24 rotates continuously inside the liquid containing the detergent, and the lower end of the filter plate 24 is cleaned by centrifugal force. The filter plate 24 is set as a metal plate, which can better filter the oil smoke in the air, and the metal plate is easier to clean under the action of liquid. The wrapping shell 34 plays a buffering role. When the electric telescopic rod 14 moves downward, the lower end of the air inlet pipe 23 is separated from the arc groove 17. At this time, the liquid containing the detergent flows into the inside of the matching cylinder 15 through the arc groove 17. At this time, there is still liquid containing the detergent on the filter plate 24. At this time, the water tank 30 and the drive motor 28 continue to start. The clean water provided by the water tank 30 and the rotating filter plate 24 further rinse the residual liquid containing the detergent on the surface of the filter plate 24, and the liquid containing the detergent on the surface of the filter plate 24 is washed away, thereby improving the cleaning efficiency of the filter plate 24.

[0043] During use, when the controller reaches the set time value, the controller controls the electric telescopic rod 14 to start and the air pump is turned off. At this time, the electric telescopic rod 14 drives the lifting plate 13 to move upward through the driving end, and the lifting plate 13 drives the matching cylinder 15 to move upward and makes the arc groove 17 on the circular plate 16 and the lower end of the air inlet pipe 23 close to each other in a closed state. At the same time, the filter plate 24 presses the pressing pump head 19 downward to squeeze the detergent onto the circular plate 16. At this time, when the electric telescopic rod 14 rises to the maximum value, the water pump and the driving motor 28 in the water tank 30 are started. The driving motor 28 drives the primary fixed cylinder 25 to rotate through the driving end, and then drives the filter plate 24 to rotate. The water pump in the water tank 30 inputs clean water into the primary fixed cylinder 25 through the connecting pipe 32, and inputs it into the space between the circular plate 16 and the filter plate 24 through the square hole 33. The clean water and the detergent contact each other to form a liquid, and the filter plate 24 continuously rotates in the liquid, so that under the action of centrifugal force, the oil stains on the filter plate 24 interact with the liquid, so that the liquid effectively cleans the oil stains on the filter plate 24. After cleaning, the electric telescopic rod 14 moves downward, and when the lower end of the air inlet pipe 23 is separated from the arc groove 17, the liquid containing the detergent flows into the matching cylinder 15 through the arc groove 17, and the water tank 30 and the driving motor 28 rotate, so that the clean water input by the water tank 30 can flush the liquid containing the detergent remaining on the filter plate 24, and the flushed water continues to flow into the inside of the matching cylinder 15. The wrapping shell 34 prevents water from flowing out to the outside of the device to cause pollution. When the wrapping shell 34 is separated from the outer wall of the air inlet pipe 23, the driving motor 28 and the water tank 30 are turned off to complete the cleaning of the filter plate 24. At the same time, when it is used for a fixed time later, the electric telescopic rod 14 is started again to repeat the above process.

[0044] The remaining structures are the same as those of Example 1.

[0045] Example 3, reference Figure 8-Figure 9 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that a collecting assembly is installed at the lower end of the lifting plate 13, and the collecting assembly includes a collecting cylinder 20 arranged at the lower end of the lifting plate 13, a drain pipe 21 arranged at the lower end of the collecting cylinder 20, and a connecting pipe 22 arranged between the collecting cylinder 20 and the matching cylinder 15.

[0046] Specifically, the collecting component is used to collect water containing detergent after use and water used during flushing. When the water flows into the matching cylinder 15, it flows into the collecting cylinder 20 through the connecting tube 22. The user regularly processes the liquid in the collecting cylinder 20, discharges the liquid in the collecting cylinder 20 through the drain pipe 21 and performs subsequent processing.

[0047] During use, when the lower end of the air inlet pipe 23 is separated from the arc-shaped groove 17, the liquid containing the detergent and the flushing liquid flows into the matching cylinder 15 through the arc-shaped groove 17, and the liquid in the matching cylinder 15 flows into the collecting cylinder 20 through the connecting pipe 22 for collection. The user processes it regularly and discharges the liquid inside the collecting cylinder 20 through the drain pipe 21.

[0048] The remaining structure is the same as that of Example 2.

[0049] Based on Examples 1-3, the working principle of the present invention is as follows: when the controller reaches the set time value, the controller controls the electric telescopic rod 14 to start and the air pump is turned off. At this time, the electric telescopic rod 14 drives the lifting plate 13 to move upward through the driving end, and the lifting plate 13 drives the matching cylinder 15 to move upward and makes the arc groove 17 on the circular plate 16 and the lower end of the air inlet pipe 23 close to each other in a closed state. At the same time, the filter plate 24 presses the push-type pump head 19 downward to squeeze the detergent onto the circular plate 16.

[0050] When the electric telescopic rod 14 rises to the maximum value, the water pump in the water tank 30 and the driving motor 28 are started. The driving motor 28 drives the primary fixed cylinder 25 to rotate through the driving end, and then drives the filter plate 24 to rotate. The water pump in the water tank 30 inputs clean water into the primary fixed cylinder 25 through the connecting pipe 32, and inputs it into the space between the circular plate 16 and the filter plate 24 through the square hole 33. The clean water and the detergent contact each other to form a liquid, and the filter plate 24 is continuously rotated in the liquid. Under the action of centrifugal force, the oil stains on the filter plate 24 interact with the liquid, so that the liquid effectively cleans the oil stains on the filter plate 24.

[0051] After cleaning is completed, the electric telescopic rod 14 moves downward, and when the lower end of the air inlet pipe 23 is separated from the arc-shaped groove 17, the liquid containing the detergent flows into the matching cylinder 15 through the arc-shaped groove 17, and the water tank 30 and the driving motor 28 rotate, so that the clean water input by the water tank 30 can flush the liquid containing the detergent remaining on the filter plate 24, and the flushing water continues to flow into the inside of the matching cylinder 15. The wrapping shell 34 prevents water from flowing out to the outside of the device and causing pollution. When the wrapping shell 34 is separated from the outer wall of the air inlet pipe 23, the driving motor 28 and the water tank 30 are turned off.

[0052] When the lower end of the air inlet pipe 23 is separated from the arc groove 17, the liquid containing the detergent and the flushing liquid flows into the matching cylinder 15 through the arc groove 17, and the liquid in the matching cylinder 15 flows into the collecting cylinder 20 through the connecting pipe 22 for collection. The user processes it regularly and discharges the liquid in the collecting cylinder 20 through the drain pipe 21 to complete the cleaning of the filter plate 24. At the same time, when it is used for a fixed time, the electric telescopic rod 14 is started again to repeat the above process.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
