Description

Technical Field

[0001] The present invention relates to the technical field of temperature and humidity measurement, and specifically to a temperature and humidity detection transmitter. Background Art

[0002] A temperature and humidity detection transmitter is a device used to measure the environmental temperature and humidity and convert the measured data into a signal that can be transmitted.

[0003] During the process of measuring temperature and humidity by a temperature and humidity detection transmitter, in order to reduce the influence of external dust particles entering the internal detection components of the temperature and humidity detection transmitter, a mesh hole is provided at the air inlet of the temperature and humidity detection transmitter. Due to the setting of the mesh hole, the intake mesh hole has a certain surface area and material properties, and is prone to adsorbing water vapor in the air. When humid air passes through the intake mesh hole, part of the water vapor will be adsorbed on the surface of the mesh hole, causing the humidity of the air entering the transmitter for detection to change, resulting in the detection result not accurately reflecting the humidity of the actual environment. And under some specific conditions, such as when the environmental temperature is relatively low and the air humidity is relatively high, water vapor condensation may occur at the intake mesh hole. The condensed water droplets will further adsorb and retain more moisture, and will also hinder the normal flow of air, making the humidity distribution of the air entering the transmitter uneven. This will not only affect the accuracy of humidity detection, but may also cause fluctuations or lags in the detected value. For this reason, we propose a temperature and humidity detection transmitter. Summary of the Invention

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0032] Embodiment 1

[0033] Please refer to Figures 1-10 , a temperature and humidity detection transmitter in the figure, including a transmitter housing 101. Inside the transmitter housing 101, there are arranged a temperature detection component 102 for temperature detection and a humidity detection component 103 for humidity detection. An air inlet hole 104 and an air outlet grille 105 are provided on the transmitter housing 101. The air inlet hole 104 and the air outlet grille 105 are symmetrically arranged on both sides of the transmitter housing 101;

[0034] It should be noted here that: the temperature detection component 102 and the humidity detection component 103 are conventional detection components in the technical field of temperature and humidity transmitters. The connection methods, working principles and operation methods of the temperature detection component 102 and the humidity detection component 103 are regarded as prior art in this application and will not be elaborated here;

[0035] It further includes:

[0036] An installation box 3, fixed inside the transmitter housing 101 and communicated with the air inlet hole 104;

[0037] The first dust-proof component is arranged on the transmitter housing 101 and is used for filtering and dust-proofing the air passing through the air outlet grille 105;

[0038] And, an air intake adaptive air flow control mechanism is arranged on the installation box 3, and a second dust-proof component for filtering the air intake after air intake control is arranged on the installation box 3;

[0039] The air intake adaptive air flow control mechanism includes a fan 401 installed inside the air intake hole 104 for air intake pumping. The upper end of the installation box 3 is connected in a communicating manner with a telescopic bellows 402. A plurality of groups of flow holes 403 are formed in the bellows 402. An installation disk 404 is fixed at the end of the bellows 402 away from the installation box 3. An elevating circular plate 6 is arranged above the installation disk 404. A connecting component for auxiliary connection is arranged between the elevating circular plate 6 and the installation disk 404. An elevating component for auxiliary lifting and a pressing component for pressing the installation disk 404 during the lifting process are arranged on the elevating circular plate 6;

[0040] It should be noted here that when the temperature and humidity detection transmitter is in use, through the mutual cooperation of the air intake adaptive air flow control mechanism and various components, according to different detection environments, it can not only expand the micropores of each group of flow holes 403 on the bellows 402 to accelerate the air flow speed and reduce water vapor adsorption, but also shrink the micropores of each group of flow holes 403 on the bellows 402 to improve the detection sensitivity. And through the periodic expansion and contraction of the flow holes 403 on the bellows 402, a "breathing effect" is formed. The air flow pulsation generated by this effect can purge the hole wall to prevent dust and particulate matter from blocking the micropores, avoiding problems such as poor air circulation and uneven humidity distribution caused by micropore blockage. At the same time, the purging effect of the air flow can reduce the adsorption of water vapor on the surface of the flow holes 403, making the air entering the transmitter closer to the humidity of the actual environment and improving the detection accuracy.

[0041] Preferably, the second dust-proof component includes an installation cylinder 501 fixed on the installation box 3. The bellows 402, the installation disk 404 and the elevating circular plate 6 are located inside the installation cylinder 501. A plurality of groups of filter holes 502 for filtering during the air flow process are formed in the installation cylinder 501. A separating component for scraping and separating the inner wall of the installation cylinder 501 during the lifting process is arranged on the elevating circular plate 6;

[0042] It should be noted here that during the whole process of air entering for detection and discharging outward, the dust particles in the air entering the circulation are filtered through the groups of flow holes 403 on the bellows 402 and the groups of filter holes 502 on the installation cylinder 501, and then combined with the filter screen 202 on the installation groove 201 to prevent the entry of external dust, so as to provide dust-proof protection for the temperature detection component 102 and the humidity detection component 103 inside the transmitter housing 101, facilitating more accurate detection operations.

[0043] Preferably, four sets of connecting components are evenly distributed between the mounting disk 404 and the lifting circular plate 6. The connecting component includes a mounting block 701 fixed to the opposite sides of the mounting disk 404 and the lifting circular plate 6. A ball head 703 is rotatably connected to the mounting block 701 through a spherical groove 702. A telescopic component for assisting telescopic connection is arranged between the two ball heads 703. The telescopic component includes a first sleeve 801 and a first sliding rod 802 arranged between the two ball heads 703. The first sliding rod 802 is slidably connected to the first sleeve 801. One ends of the first sleeve 801 and the first sliding rod 802 are respectively fixed to the two ball heads 703.

[0044] It should be noted here that: due to the rotatable connection of the ball head 703 by the spherical groove 702 on the mounting block 701 and the telescopic connection of the first sleeve 801 and the first sliding rod 802, it is convenient for the telescopic connection between the lifting circular plate 6 and the mounting disk 404 in the horizontal direction.

[0045] Preferably, the extrusion component includes a rectangular frame 1001 centrally fixed to the upper end of the mounting disk 404. A mounting shaft 1002 is rotatably connected to the lifting circular plate 6. A cam 1003 for abutting and extruding against the four sides inside the rectangular frame 1001 is fixed to the mounting shaft 1002. The cam 1003 is located inside the rectangular frame 1001. A driving component for driving the mounting shaft 1002 is arranged on the lifting circular plate 6.

[0046] It should be noted here that: during the process of driving the mounting disk 404 and the corrugated pipe 402 to move up and down by the rotation of the mounting shaft 1002, as the mounting shaft 1002 rotates, the cam 1003 is driven to rotate. During the rotation of the cam 1003, due to the reciprocating abutting and extruding action of the cam 1003 against the inner periphery of the rectangular frame 1001 on the mounting disk 404 and the telescopic connection of the connecting component and the telescopic component to the mounting disk 404, the mounting disk 404 and the corrugated pipe 402 perform reciprocating swinging in the front, back, left, and right directions in the horizontal direction while moving up and down.

[0047] Preferably, the driving component includes a first gear 1101 fixed to the mounting shaft 1002. A driving shaft 1102 is rotatably connected to the lifting circular plate 6. A second gear 1103 is fixed to the driving shaft 1102. The first gear 1101 and the second gear 1103 are meshed with each other. A mounting motor 1104 for driving the driving shaft 1102 is installed at the upper end of the lifting circular plate 6.

[0048] It should be noted here that by installing the motor 1104, the drive shaft 1102 is rotated. During the rotation of the drive shaft 1102, the second gear 1103 is driven to rotate. During the rotation of the second gear 1103, the installation shaft 1002 is rotated through the meshing transmission between the second gear 1103 and the first gear 1101.

[0049] Preferably, the lifting assembly includes a threaded tube 901 rotatably connected to the lifting circular plate 6. One end of the threaded tube 901 is fixed to one end of the installation shaft 1002. A threaded rod 902 is threadedly engaged with the threaded tube 901. One end of the threaded rod 902 is fixed inside the installation cylinder 501. Two groups of second sleeves 903 are fixed to the upper end of the lifting circular plate 6, and the two groups of second sleeves 903 are symmetrically arranged on both sides of the threaded tube 901. A second sliding rod 904 is slidably connected to the second sleeve 903. One end of the second sliding rod 904 is fixed to the inner wall of the installation cylinder 501;

[0050] It should be noted here that by the driving assembly, the installation shaft 1002 is rotated. During the rotation of the installation shaft 1002, the threaded tube 901 is driven to rotate. During the rotation of the threaded tube 901, through the meshing transmission between the threaded tube 901 and the threaded rod 902 and the sliding guiding action of the second sleeve 903 and the second sliding rod 904, the lifting circular plate 6 is forced to move up and down inside the installation cylinder 501.

[0051] Preferably, the separation assembly includes an annular scraping plate 1201 disposed inside the installation cylinder 501 and abutted against the inner wall of the installation cylinder 501. The annular scraping plate 1201 and the lifting circular plate 6 are connected and fixed by a plurality of connecting rods 1202;

[0052] It should be noted here that during the lifting of the lifting circular plate 6, the annular scraping plate 1201 is driven to move up and down synchronously through the connecting rod 1202. Since the annular scraping plate 1201 is abutted against the inner wall of the installation cylinder 501, through the up and down movement of the annular scraping plate 1201, the dust particles adhered to the inner wall of the installation cylinder 501 after filtration are scraped and separated.

[0053] Preferably, the first dust-proof assembly includes an installation groove 201 opened on the outer side of the transmitter housing 101. The installation groove 201 communicates with the air outlet grille 105. A filter screen 202 is installed inside the installation groove 201;

[0054] It should be noted here that during the entire process of air intake, detection, and exhaust, dust particles in the incoming air are filtered through the groups of circulation holes 403 on the corrugated pipe 402 and the groups of filter holes 502 on the mounting cylinder 501. In addition, the filter screen 202 on the mounting groove 201 is used to prevent external dust from entering, providing dust protection for the temperature detection component 102 and humidity detection component 103 inside the transmitter housing 101, which facilitates more accurate detection operations.

[0055] In this solution, a temperature and humidity detection transmitter includes the following steps:

[0056] When the temperature and humidity detection transmitter is in use, the transmitter housing 101 is installed at a designated position by means of bolt fixation. After installation, driven by the fan 401, external air is conveyed into the interior of the transmitter housing 101 through the air inlet hole 104 and the mounting box 3. During the conveying process, the incoming air passes through the circulation holes 403 of the corrugated pipe 402 and the filter holes 502 of the mounting cylinder 501 and is conveyed into the interior of the transmitter housing 101 (see Figure 9 ). The air conveyed into the interior of the transmitter housing 101 is subjected to temperature and humidity detection by the temperature detection component 102 and humidity detection component 103. After the detection is completed, the detected air is exhausted outward through the air outlet grille 105. During the entire process of air intake, detection, and exhaust, dust particles in the incoming air are filtered through the groups of circulation holes 403 on the corrugated pipe 402 and the groups of filter holes 502 on the mounting cylinder 501. In addition, the filter screen 202 on the mounting groove 201 is used to prevent external dust from entering, providing dust protection for the temperature detection component 102 and humidity detection component 103 inside the transmitter housing 101, which facilitates more accurate detection operations;

[0057] During the detection process, real-time identification is carried out through the humidity detection component 103. When the detected humidity is high, the drive component is used to rotate the mounting shaft 1002. During the rotation of the mounting shaft 1002, the threaded tube 901 is driven to rotate. During the rotation of the threaded tube 901, through the meshing transmission between the threaded tube 901 and the threaded rod 902 and the sliding guiding effect between the second sleeve 903 and the second slide bar 904, the lifting circular plate 6 is forced to move upward inside the mounting cylinder 501. During the upward movement of the lifting circular plate 6, through the connection between the lifting circular plate 6 and the mounting plate 404 by the connection component and the telescopic component, the mounting plate 404 is driven to move upward. Through the upward movement of the mounting plate 404, the corrugated tube 402 is stretched. During the stretching process, due to the flexible effect of the material of the corrugated tube 402 itself, the micropores of each group of flow holes 403 on the corrugated tube 402 expand, accelerating the air flow velocity, reducing water vapor adsorption, and preventing a large amount of water vapor in the air from adsorbing on the inner side of the corrugated tube 402 during high humidity detection, ensuring the accuracy of detection. When the detected humidity is low, through transmission, the lifting circular plate 6 is forced to move downward inside the mounting cylinder 501. During the downward movement of the lifting circular plate 6, through the connection between the lifting circular plate 6 and the mounting plate 404 by the connection component and the telescopic component, the mounting plate 404 is driven to move downward. Through the downward movement of the mounting plate 404, the corrugated tube 402 is contracted. During the contraction process, due to the flexible effect of the material of the corrugated tube 402 itself, the micropores of each group of flow holes 403 on the corrugated tube 402 shrink. The reduction of the micropores will reduce the cross-sectional area of the intake channel. According to the principle of fluid continuity, when the intake air volume is constant, the reduction of the channel cross-sectional area will lead to an increase in the air flow velocity. The appropriately increased air flow velocity can make the air pass through the detection area inside the transmitter more quickly, reducing the residence time of the air in the detection area, so that new air to be detected can be brought into the detection area more quickly in a timely manner, reflecting the changes in the environmental temperature and humidity, and helping to maintain the sensitivity of detection. During the telescopic process of the corrugated tube 402, the flow holes 403 on the corrugated tube 402 will expand and contract periodically, forming a "breathing effect". The air flow pulsation generated by this effect can purge the hole wall, preventing dust and particulate matter from blocking the micropores, avoiding problems such as poor air circulation and uneven humidity distribution caused by micropore blockage. At the same time, the purging effect of the air flow can reduce the adsorption of water vapor on the surface of the flow holes 403, making the air entering the transmitter closer to the humidity of the actual environment and improving the detection accuracy;

[0058] During the process of driving the mounting disk 404 and the corrugated pipe 402 to move up and down by the rotation of the mounting shaft 1002, as the mounting shaft 1002 rotates, the cam 1003 is driven to rotate. During the rotation of the cam 1003, through the reciprocating abutting and squeezing action of the cam 1003 against the inner periphery of the rectangular frame 1001 on the mounting disk 404 and the telescopic connection action of the connection assembly and the telescopic assembly on the mounting disk 404, the mounting disk 404 and the corrugated pipe 402 perform reciprocating swinging in the front, back, left and right directions in the horizontal direction while moving up and down (see Figure 10 ). Through the swinging of the corrugated pipe 402, the separation of adsorbed particulate matter and water vapor on the corrugated pipe 402 is more effectively assisted.
