Description

Technical Field

[0001] The present invention relates to the technical field of temperature and humidity transmitter devices, and particularly to a wall-mounted temperature and humidity transmitter. Background Art

[0002] A temperature and humidity transmitter is a device that can convert physical quantities of temperature and humidity in the environment into electrical signals that can be transmitted and processed.

[0003] In industrial scenarios, such as electronic manufacturing workshops, where strict requirements are placed on the environmental temperature and humidity, temperature and humidity transmitters can monitor and feedback data in real time to help the control system maintain appropriate temperature and humidity, ensuring the production quality of electronic products. In agricultural planting, greenhouse greenhouses rely on temperature and humidity transmitters to accurately grasp the internal temperature and humidity changes, so as to ventilate, irrigate, shade, etc. in a timely manner, creating a good environment for crop growth. In warehousing and logistics, for warehouses storing temperature and humidity-sensitive items such as food, medicine, and precision instruments, temperature and humidity transmitters can ensure the stability of the storage environment and prevent the items from deteriorating and being damaged. In smart homes, residents can perceive the indoor temperature and humidity through temperature and humidity transmitters and cooperate with smart home appliances to improve the living comfort. In the medical field, in places such as operating rooms and drug storage rooms, temperature and humidity transmitters play a key role in ensuring the safety of the medical environment and the quality of drugs. In scientific research experiments, it provides data support for the precise control of the experimental environment.

[0004] A wall-mounted temperature and humidity transmitter is a common type of temperature and humidity transmitter, specifically designed for wall-mounted installation to accurately monitor the temperature and humidity in a specific space. Its appearance is usually flat, with mounting holes on the back, which can be easily fixed on the wall without occupying too much space.

[0005] When a wall-mounted temperature and humidity transmitter is installed in a poorly ventilated space, such as a small corner of a warehouse or a well-sealed equipment machine room, the natural air flow is weak, and it is difficult to quickly update the air around the transmitter. This will cause the measured temperature and humidity values to only represent a small local area and cannot reflect the overall environmental conditions. At this time, using a blower on the wall-mounted temperature and humidity transmitter to guide the air flow can promote the full circulation of air, allowing the air in different areas to evenly flow through the transmitter, thereby obtaining more representative temperature and humidity data. During the process of using a blower to guide the air flow on the wall-mounted temperature and humidity transmitter, the air flow blown by the blower is usually fast and unstable, which may cause the local air flow around the sensor to be too fast or too slow, resulting in measurement errors and unable to accurately reflect the true temperature and humidity conditions. Moreover, the fast air flow may affect the heat exchange and water vapor adsorption and desorption processes of the sensor. For example, for a thermal resistance temperature sensor, a fast air flow will accelerate heat dissipation and make the measured temperature lower; for a capacitive humidity sensor, the air flow may interfere with the adsorption balance of water vapor on the sensing element, resulting in inaccurate humidity measurement. Therefore, we propose a wall-mounted temperature and humidity transmitter. Summary of the Invention

[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 of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1

[0033] Please refer to Figures 1-10 , the wall-mounted temperature and humidity transmitter shown in the figure includes a temperature and humidity transmitter housing 101. A display screen 102 for displaying after temperature and humidity detection is provided on the front side of the temperature and humidity transmitter housing 101. Mounting blocks 103 for assisting wall-mounted installation are fixed at the four corners of the back surface of the temperature and humidity transmitter housing 101. A temperature detection module 104 and a humidity detection module 105 for detecting temperature and humidity are installed inside the temperature and humidity transmitter housing 101;

[0034] It should be noted here that: the display screen 102, the temperature detection module 104, and the humidity detection module 105 are conventional detection components in the technical field of temperature and humidity transmitters. The connection methods, working principles, and operation methods among the display screen 102, the temperature detection module 104, and the humidity detection module 105 are regarded as existing technologies in this application and will not be elaborated here;

[0035] It further includes:

[0036] An auxiliary air intake component for auxiliary detection provided on the temperature and humidity transmitter housing 101. The auxiliary air intake component includes an installation cylinder 201 installed at the bottom of the temperature and humidity transmitter housing 101 in a communicating manner. An axial flow fan 202 for auxiliary suction and intake is installed inside the installation cylinder 201. A plurality of air outlet grilles 203 for post-detection air outlet are opened at the upper end of the temperature and humidity transmitter housing 101. A buffer box 3 is fixed at the inner bottom of the temperature and humidity transmitter housing 101. The installation cylinder 201 communicates with the inside of the buffer box 3, and a heat and humidity exchange and balance component is provided on the buffer box 3;

[0037] The heat and humidity exchange and balance component includes installation grooves 401 symmetrically opened on both sides of the buffer box 3. A rectangular plate 402 is connected inside the installation grooves 401 through a telescopic component. A plurality of metal thin plates 403 arranged in an inclined state are connected on the opposite sides of the two buffer boxes 3 through a connection component. An L-shaped frame 8 is fixed on the two rectangular plates 402. A transmission component for driving the two L-shaped frames 8 is provided outside the buffer box 3. An adjustment component for adjusting the use angle of the metal thin plates 403 during the transmission of the rectangular plate 402 is provided inside the installation grooves 401; the metal thin plates 403 on one side of the two rectangular plates 402 are arranged in a staggered state;

[0038] It should be noted here that: during the use of the wall-mounted temperature and humidity transmitter, through the auxiliary air intake component, the air in the installation area circulates on the temperature and humidity transmitter housing 101, facilitating the rapid update of the air around the transmitter. During the air circulation process, through the heat and humidity exchange and balance component, on the one hand, the heat in the air flow is transferred and balanced to avoid local overheating or overcooling areas interfering with temperature measurement. On the other hand, the humidity in the air flow is adsorbed and released to make the humidity distribution more uniform, thereby improving the accuracy of temperature and humidity measurement. Moreover, the staggered arrangement of the metal thin plates 403 extends the flow path of the air flow, increases the air flow resistance, plays a role in buffering the incoming air flow, ensures the smoothness of the air flow flowing to the temperature detection module 104 and the humidity detection module 105, reduces the influence of the high-speed air flow on the measurement accuracy of the sensor, and improves the accuracy of temperature and humidity detection.

[0039] Preferably, the connecting component includes a mounting shaft 501 rotatably connected to the rectangular plate 402. Two groups of connecting plates 502 are fixed on the mounting shaft 501. The two groups of connecting plates 502 are symmetrically arranged on both sides of the rectangular plate 402. One end of each of the two groups of connecting plates 502 is fixedly connected to one side of the metal sheet 403.

[0040] It should be noted here that: through the mounting shaft 501 and the connecting plates 502, it is convenient to assist in the rotatable connection of the metal sheet 403.

[0041] Preferably, the transmission component includes an L-shaped plate 1001 fixed to the L-shaped frame 8. Two groups of fixing plates 1002 are fixed on the outer side of the flow buffer box 3. The two groups of L-shaped plates 1001 are located between the two groups of fixing plates 1002. Two groups of threaded sleeves 1003 are fixed on the two groups of L-shaped plates 1001. A double-headed lead screw 1004 is rotatably connected between the two groups of fixing plates 1002. The two groups of threaded sleeves 1003 are respectively engaged with the two ends of the double-headed lead screw 1004. A driving motor 1005 for driving the double-headed lead screw 1004 is installed on the fixing plate 1002. Two guide rods 1006 are fixed between the two groups of fixing plates 1002. The two groups of guide rods 1006 are symmetrically arranged at both ends of the double-headed lead screw 1004. The L-shaped plate 1001 is slidably connected to the two groups of guide rods 1006; the thread directions at both ends of the double-headed lead screw 1004 are opposite.

[0042] It should be noted here that: the driving motor 1005 rotates the double-headed lead screw 1004. Since the thread directions at both ends of the double-headed lead screw 1004 are opposite, during the rotation of the double-headed lead screw 1004, through the meshing transmission between the two groups of threaded sleeves 1003 and the two ends of the double-headed lead screw 1004 respectively, the two groups of L-shaped plates 1001 are forced to move. During the movement of the two groups of L-shaped plates 1001, through the sliding guiding action of the two groups of guide rods 1006, the two groups of L-shaped plates 1001 and the L-shaped frame 8 after being stressed move closer to or away from each other.

[0043] Preferably, two groups of telescopic components are evenly distributed at the upper and lower ends of the rectangular plate 402.

[0044] It should be noted here that: through the two groups of telescopic components, the telescopic guiding effect is ensured.

[0045] Preferably, the telescopic component includes two groups of sleeves 601 fixed to the rectangular plate 402. A sliding rod 602 is slidably connected to the two groups of sleeves 601. One end of the sliding rod 602 is fixed to the inner wall of the installation groove 401.

[0046] It should be noted here that: through the two groups of sleeves 601 and the sliding rod 602, it is convenient to assist in the telescopic guiding of the rectangular plate 402.

[0047] Preferably, the adjusting component includes a gear 702 fixed on the mounting shaft 501, and a rack 701 is fixed inside the mounting groove 401. The gear 702 and the rack 701 are meshed with each other;

[0048] It should be noted here that during the movement of the rectangular plate 402, through the meshing transmission between the gear 701 on the mounting shaft 501 and the rack 702 inside the mounting groove 401, the mounting shaft 501 rotates. During the rotation of the mounting shaft 501, through the connection of the connecting plate 502, the metal sheet 403 is driven to rotate synchronously. By rotating the metal sheet 403, the inclination angle of the metal sheet 403 is increased.

[0049] Preferably, a flexible sealing belt 9 for sealing the mounting groove 401 is installed inside the mounting groove 401. The rectangular plate 402, the adjusting component and the telescopic component are located between the two flexible sealing belts 9 of the mounting groove 401. The L-shaped frame 8 and the connecting plate 502 are respectively installed and fixed on the two flexible sealing belts 9;

[0050] It should be noted here that through the flexible sealing belt 9, the mounting groove 401 and the outside of the flow buffer tank 3 are sealed to prevent the air inside the flow buffer tank 3 from flowing out to the outside of the flow buffer tank 3 through the mounting groove 401.

[0051] In this solution, the wall-mounted temperature and humidity transmitter includes the following steps:

[0052] During the use of the wall-mounted temperature and humidity transmitter, the multiple mounting blocks 103 on the temperature and humidity transmitter housing 101 are installed and fixed at the specified mounting position by bolts. After the installation is completed, in order to accurately reflect the temperature and humidity conditions in the area after the wall-mounted temperature and humidity transmitter is installed, the axial flow fan 202 on the mounting cylinder 201 is started. Through the driving action of the axial flow fan 202, part of the air in the area where the wall-mounted temperature and humidity transmitter is installed is sucked into the inside of the temperature and humidity transmitter housing 101 and discharged outward from each air outlet grille 203, so as to achieve the purpose of the air circulation in the installation area on the temperature and humidity transmitter housing 101. During the circulation process, the temperature detection module 104 and the humidity detection module 105 inside the temperature and humidity transmitter housing 101 detect the humidity and temperature of the air during the circulation process in real time, and after the detection is completed, the specific values of the temperature and humidity are displayed on the display screen 102 to achieve the effect of temperature and humidity detection;

[0053] When driving air to circulate through the housing 101 of the temperature and humidity transmitter, the incoming air passes through the flow buffer box 3. During this process, the air flows through the staggered metal sheets 403 on one side of each group of the two groups of rectangular plates 402. Since the metal sheets 403 have good heat conduction and humidity adsorption and desorption characteristics, when the air flow passes through the staggered metal sheets 403, the metal sheets 403 can fully exchange heat and moisture with the air flow. On the one hand, the heat in the air flow is transferred and balanced to avoid local overheating or overcooling areas interfering with temperature measurement. On the other hand, the humidity in the air flow is adsorbed and released to make the humidity distribution more uniform, thereby improving the accuracy of temperature and humidity measurement. Moreover, the staggered arrangement of the metal sheets 403 extends the flow path of the air flow, increases the air flow resistance, and plays a role in buffering the incoming air flow, ensuring the smoothness of the air flow flowing to the temperature detection module 104 and the humidity detection module 105, reducing the influence of high-speed air flow on the measurement accuracy of the sensor, and improving the accuracy of temperature and humidity detection;

[0054] Moreover, during the process of air circulation and control through the auxiliary air intake component and the heat and moisture exchange and balance component, when the axial flow fan 202 on the auxiliary air intake component needs to inhale and circulate air with a greater output power, the driving motor 1005 is synchronously driven. Through the driving motor 1005, the double-headed lead screw 1004 rotates. Since the thread directions at both ends of the double-headed lead screw 1004 are set to be opposite, during the rotation of the double-headed lead screw 1004, the two groups of thread sleeves 1003 are respectively engaged with the two ends of the double-headed lead screw 1004 for transmission, so that the two groups of L-shaped plates 1001 are forced to move. During the movement of the two groups of L-shaped plates 1001, through the sliding and guiding action of the two groups of guide rods 1006, the two groups of L-shaped plates 1001 and the L-shaped frames 8 after being stressed move closer to each other. During the movement of the two groups of L-shaped frames 8, the two groups of rectangular plates 402 are driven to move closer inside the two groups of installation grooves 401 respectively. Through the closer movement of the two groups of rectangular plates 402, the distance between the two adjacent metal sheets 403 between the two groups of rectangular plates 402 is reduced. And during the movement of the rectangular plates 402, through the meshing transmission between the gear 701 on the installation shaft 501 and the rack 702 inside the installation groove 401, the installation shaft 501 rotates. During the rotation of the installation shaft 501, through the connection of the connecting plate 502, the metal sheets 403 are driven to rotate synchronously. By rotating the metal sheets 403, the inclination angle of the metal sheets 403 is increased. By reducing the distance between the two adjacent metal sheets 403 and increasing the inclination angle of the metal sheets 403, the metal sheets 403 between the two groups of rectangular plates 402 are arranged more closely (see Figure 10) When the air flow passes through, the resistance will increase significantly, which can greatly reduce the air flow speed. At the same time, increasing the inclination angle can make the air flow generate more reflections and deflections between the metal sheets 403, further consuming the air flow energy and slowing down the air flow speed, ensuring the smooth air flow reaching the temperature and humidity sensor and preventing measurement deviation caused by the impact of high-speed air flow.
