[0023] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] According to an embodiment of the present invention, the temperature and humidity sensor includes a housing 2, a detection tube 3, a detection probe, and a display screen 5. The detection tube 3 is arranged on a first side of the housing 2, and a through-tube 7 is arranged on a second side of the housing 2. The through-tube 7 extends towards the first side of the housing 2 and connects to the detection tube 3. The detection tube 3 extends along a first direction, and caps 4 are arranged at both ends of the detection tube 3 to seal it. A screw 402 is arranged inside the detection tube 3, and multiple filter elements 403 are arranged on the screw 402. Both ends of the screw 402 pass through the caps 4 and are slidably connected to them. The detection probe is arranged on the first side of the housing 2, and at least part of the detection probe enters the detection tube 3. The display screen 5 is electrically connected to the detection probe and is used to display the detection results. The housing 2, as the main structure of the sensor, provides protection for the internal components. The detection tube 3, located on the first side of the housing 2, houses the detection probe and filter elements 403, etc. The through-tube 7, located on the second side of the housing 2, extends and connects to the detection tube 3, ensuring that air can smoothly enter the detection tube 3 for temperature and humidity measurement. The detection tube 3 extends in a specific direction and is sealed at both ends by the sleeve cap 4, forming a closed measurement space. The screw 402 passes through and slides through the sleeve cap 4, allowing the filter 403 to move on the screw 402 for easy maintenance and replacement. The display screen 5 is electrically connected to the detection probe, displaying the detected temperature and humidity data in real time for easy reading by the user. The detection probe is located on the first side of the housing 2, with part of the probe entering the detection tube 3 to directly contact the air being measured for accurate temperature and humidity measurement.

[0025] The temperature and humidity sensor according to the present invention has the advantages of high detection accuracy, resistance to clogging, and long service life.

[0026] In some embodiments, the temperature and humidity sensor further includes an orifice plate 404, which is arranged on the screw 402. The first end of the filter 403 is connected to the orifice plate 404, and the second end of the filter 403 extends toward the end cap 4 of the screw 402.

[0027] Specifically, the perforated plate 404 is fixed to the screw 402, serving as a support structure for the filter element 403. One end of the filter element 403 is connected to the perforated plate 404, and the other end extends to the cover 4, forming an effective filtration layer. The filter element 403 is used to filter and adsorb dust and impurities in the air. The perforated plate 404 improves the stability of the filter element 403, preventing it from tilting and affecting the adsorption effect.

[0028] Optionally, the filter 403 on the screw 402 can be divided into two or more layers. Each layer of filter 403 has a different material and filter pore size, which can filter and adsorb impurities of different particle sizes, thereby improving the overall filtration effect.

[0029] In some embodiments, a plurality of filter elements 403 are arranged around the screw 402, and the filter elements 403 are equally spaced from any adjacent filter elements 403.

[0030] Specifically, the filter elements 403 are evenly arranged around the screw 402, ensuring the uniformity of airflow through the filter elements 403 and improving measurement accuracy. Multiple filter elements 403 are distributed in a ring around the screw 402, and the equal spacing between adjacent filter elements 403 ensures uniform airflow and avoids localized airflow obstructions affecting the test results.

[0031] In some embodiments, two sets of filter plates 403 are arranged along the length of the screw 402. The two sets of filter plates 403 are symmetrical about the perforated plate 404, and each set of filter plates 403 is distributed at equal intervals around the screw 402.

[0032] Specifically, the symmetrical arrangement of two sets of filter plates 403 about the perforated plate 404 can extend the filtration of air by the filter plates 403. The two sets of filter plates 403 are located on both sides of the perforated plate 404 and connected to the perforated plate 404 to fix the filter plates 403. As a result, the number of filter plates 403 on the screw 402 increases, the effective filtration area increases, and the filtration effect on air is improved.

[0033] Optionally, the filter 403 can have a three-dimensional structure, such as a corrugated or honeycomb structure on its surface, to increase the filtration surface area and improve filtration capacity. Simultaneously, the three-dimensional structure can further optimize the uniformity of airflow and reduce localized airflow obstruction by altering the airflow direction.

[0034] In some embodiments, a through hole 401 is provided in the center of the cover 4, and the screw 402 passes through the through hole 401 and is threadedly connected to the cover 4 through the through hole 401.

[0035] Specifically, the design of the perforation 401 and the threaded connection allows the cover 4 to be securely fixed to the screw 402 while facilitating disassembly. The perforation 401, positioned in the center of the cover 4, also prevents the filter 403 from colliding with the wall of the detection tube 3 due to misalignment of the screw 402. An internal thread can be provided within the perforation 401, allowing the cover 4 to be threadedly connected to the screw 402 for easy fixation and to prevent movement of the screw 402 relative to the detection tube 3. The cover 4 can also be snapped onto or threaded to the end of the detection tube 3, improving the airtightness of the detection tube 3.

[0036] Optionally, a sealing ring can be added to the side of the cover 4 that connects to the detection tube 3. The sealing ring can be an annular sealing ring, a rubber sealing gasket, etc., to improve the sealing performance and prevent air leakage.

[0037] Optionally, a transparent window or observation hole can be provided on the cover 4 or the detection tube 3 to facilitate real-time observation of the working status of the screw 402 and the filter 403 and to detect problems in a timely manner.

[0038] In some embodiments, a mounting base 1 is provided on the second side of the housing 2, and a connection interface 6 is provided on the mounting base 1. At least a portion of the through pipe 7 enters the connection interface 6 and communicates with the air hole 8 on the detection pipe 3. The air hole 8 is used to receive air from the through pipe 7.

[0039] Specifically, the design of the mounting base 1 and the interface 6 facilitates the installation and fixation of the sensor, while ensuring that air can flow from the through pipe 7 into the detection tube 3. The mounting base 1 facilitates the fixation of the equipment, and the alignment of the interface 6 with the air hole 8 of the detection tube 3 facilitates the connection between the through pipe 7 and the detection tube 3. The through pipe 7 sends air into the detection tube 3 through the air hole 8, where the air comes into contact with the filter 403 on the screw 402 inside the detection tube 3 to complete the filtration. The detection probe detects the air inside the detection tube 3.

[0040] Optionally, the through tube 7 can be made of a flexible material to facilitate angle adjustment during installation and ensure alignment with the air hole 8 of the detection tube 3.

[0041] In some embodiments, the extension direction of the through tube 7 is perpendicular to the extension direction of the detection tube 3.

[0042] Specifically, the through pipe 7 is perpendicular to the detection pipe 3. When the through pipe 7 supplies air to the detection pipe 3, the air travels to both ends of the detection pipe 3 at the air hole 8. On the one hand, this reduces the size of the sensor, and on the other hand, it allows the air to fully and evenly contact the filter 403 inside the detection pipe 3, maintaining the smooth flow of air inside the detection pipe 3.

[0043] In some embodiments, a plurality of detection holes are arranged on the housing 2. The detection holes are located on the first side of the housing 2 and arranged on both sides of the display screen 5. The detection holes are connected to the detection tube 3, and the detection probes correspond one-to-one with the detection holes.

[0044] Specifically, the design of multiple detection holes increases the number of measurement points for the sensor, improving the comprehensiveness of the data. Each detection hole is connected to the detection tube 3, ensuring accurate measurement by each probe. The detection holes are arranged on the first side of the housing 2 and distributed on both sides of the display screen 5, which shortens the wiring length between the detection probe and the display screen 5, better protecting the wiring of the display screen 5. The detection probe and detection holes are used opposite each other to detect air inside the detection tube 3; multi-point detection improves the reliability of the detection data.

[0045] In some embodiments, the display screen 5 is connected to the detection tube 3, and the detection probes are distributed on both sides of the detection tube 3.

[0046] Specifically, the display screen 5 is arranged on the detection tube 3 to directly display the measurement data inside the detection tube 3, and the detection probes are distributed on both sides of the detection tube 3 to further enrich the data acquisition positions.

[0047] In some embodiments, a protective cap is provided at the end of the screw 402 to prevent the cover 4 from detaching from the screw 402.

[0048] Specifically, the protective cap located at the end of the screw 402 prevents the cover 4 from accidentally falling off, ensuring the safety of the sensor during transportation and use. The protective cap can be fixed to the end of the screw 402 via a threaded connection or a snap-fit ​​structure. Threaded connections provide higher connection strength, while snap-fit ​​structures facilitate quick installation and removal.
