Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and more specifically, to an automatic sensing device for detecting environmental temperature and humidity. Background Technology

[0002] As the core location for data storage and processing, the server room generates a lot of heat when the server equipment is running. The hot air is distributed vertically due to density differences, resulting in significant differences in temperature and humidity at different heights. For example, the ground floor is prone to forming local high humidity areas due to the accumulation of air conditioning condensate. The temperature and humidity of the middle server rack directly affect the heat dissipation efficiency of the equipment, while the top is prone to forming high temperature stagnation areas.

[0003] Currently, traditional detection methods typically involve using multiple temperature and humidity sensors to individually detect the temperature and humidity in different high-altitude areas. However, while distributed deployment of multiple sensors can cover multiple heights, it requires the additional installation of numerous lines and power supply modules, which not only increases the complexity of the computer room wiring but also makes it susceptible to electromagnetic interference from servers. Furthermore, multi-sensor calibration is difficult and data consistency is poor. Therefore, we propose an automatic temperature and humidity sensing device for detecting the environment. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an automatic sensing device for detecting environmental temperature and humidity, so as to solve the technical problem that the current automatic sensing device for detecting environmental temperature and humidity is inconvenient to use in the computer room.

[0005] To solve the above technical problems, this utility model provides the following technical solution: an automatic sensing device for detecting ambient temperature and humidity, including a lifting frame, an air pump fixedly installed on the top of the lifting frame, a three-way solenoid valve fixedly connected to the air pump's suction end, connecting pipes with different port heights fixedly installed on the connecting ends of the three-way solenoid valve, an air inlet pipe fixedly connected to the port of each connecting pipe, and the cross-sectional shape of the air inlet pipe is flat and round, and an elastic dust cover fixedly connected to the end of each air inlet pipe, and a temperature and humidity detection box fixedly connected to the air pump's outlet end;

[0006] The temperature and humidity detection box includes a box body, on one side of which a silicone hose is fixedly connected to the air outlet of an air pump, and a temperature and humidity sensor is fixedly connected between the opposing surfaces inside the temperature and humidity detection box and fits into the port of the silicone hose.

[0007] This invention utilizes a three-way solenoid valve and connecting pipes with different port heights to simultaneously or alternately extract ambient air from different heights, achieving multi-height coverage without the need for additional detection modules, thus simplifying the detection process. The lifting frame structure can also adjust the overall detection height range according to actual needs, further enhancing the device's adaptability and flexibility to different computer room layouts. At the same time, single-sensor detection avoids data inconsistencies caused by individual differences in multiple sensors (such as different accuracy deviations and drift characteristics), ensuring that temperature and humidity data in different height areas have a unified benchmark and improving data reliability.

[0008] Preferably, the dust cover has several bending grooves on its upper and lower sides, and the dust cover has bending limiting ribs embedded in the interior of both ends.

[0009] Preferably, the air intake pipe includes an outer pipe with heat insulation properties, an inner pipe is fixedly disposed inside the outer pipe, and a heat insulation cavity is formed between the outer pipe and the inner pipe.

[0010] Preferably, a vent hole is provided through the side of the box body facing the silicone tube, and a movable sealing component is used to seal the inside of the vent hole.

[0011] Preferably, the sealing assembly includes a cross fixed to the inner wall of the box, a limiting sleeve fixedly provided at the center of the cross near the side of the box, and a sealing plate that fits against the inner wall of the vent hole fixedly connected to the end of the limiting sleeve.

[0012] Preferably, a limiting rod that fits against the inner wall of the limiting sleeve is fixedly provided on the side of the cross, and a return spring that is inserted and connected to the limiting rod is fixedly provided on the side of the sealing plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model utilizes a three-way solenoid valve and connecting pipes with different port heights to allow the device to simultaneously or alternately extract ambient air at different heights. This achieves multi-height coverage without the need for additional detection modules, simplifying the detection process. The lifting frame structure can also adjust the overall detection height range according to actual needs, further enhancing the device's adaptability and flexibility to different computer room layouts. At the same time, single-sensor detection avoids data inconsistencies caused by individual differences in multiple sensors (such as different accuracy deviations and drift characteristics), ensuring that temperature and humidity data in different height areas have a unified benchmark and improving data reliability.

[0015] 2. This utility model also uses an elastic dust cover at the end of the air inlet pipe to filter dust and impurities in the air, preventing them from entering the temperature and humidity detection box and adhering to the sensor surface, thus affecting the detection accuracy. The bending groove and limiting rib design of the dust cover can not only ensure normal air entry, but also bend the dust cover to a certain angle according to the air flow direction, further improving the stability of air collection at the corresponding height. In addition, the heat insulation cavity structure of the air inlet pipe can reduce the influence of external temperature changes on the temperature of the air inside the pipe, avoid deviations in detection data, and indirectly protect the sensor from extreme temperature shocks, extending its service life.

[0022] like Figures 1 to 5As shown, this utility model relates to an automatic sensing device for detecting ambient temperature and humidity, comprising a lifting frame 1, an air pump 2 fixedly mounted on the top of the lifting frame 1, a three-way solenoid valve 3 fixedly connected to the air pump 2's suction end, connecting pipes 4 with different port heights fixedly mounted on the connecting ends of the three-way solenoid valve 3, an air inlet pipe 5 fixedly connected to the port of each connecting pipe 4, and the air inlet pipe 5 having a flat oval cross-section, and an elastic dust cover 6 fixedly connected to the end of each air inlet pipe 5, and a temperature and humidity detection box 7 fixedly connected to the air pump 2's outlet end; the air pump 2 can be used to detect ambient temperature and humidity. The design of the three-way solenoid valve 3 allows for the sequential extraction of air at the same height. The three-way solenoid valve 3 controls the connection between the connecting pipe 4 and the air pump 2 at different heights. The flat circular cross-section of the air inlet pipe 5 better conforms to the air flow trajectory. According to fluid simulation, the airflow resistance is reduced by 15% compared to the circular cross-section at the same flow rate, further reducing the air pump load. By introducing air at different heights into the temperature and humidity detection box 7 through the air pump 2, the temperature and humidity detection work at different heights can be completed, which can effectively improve the accuracy of temperature and humidity detection. Moreover, this structural design is simple, eliminates complex wiring procedures, and is easy to use.

[0023] The temperature and humidity detection box 7 includes a box body 701. A silicone hose 702, which is fixedly connected to the air outlet of the air pump 2, is fixedly installed on one side of the box body 701. A temperature and humidity sensor 8, which is in contact with the port of the silicone hose 702, is fixedly connected between the opposing surfaces inside the temperature and humidity detection box 7. The box body 701 can enclose the temperature and humidity sensor 8, which can reduce electromagnetic interference, reduce direct contact between the temperature and humidity sensor 8 and the electromagnetic source, effectively avoid electromagnetic interference, and improve the stability and accuracy of the detection data. The silicone hose 702 prevents the heat of the air pump body from being directly transferred to the pipe through the metal interface, reduces the phenomenon of pipe displacement caused by the vibration of the air pump 2, and improves the stability of air delivery.

[0024] In the embodiments of this utility model, the upper and lower sides of the dust cover 6 are provided with a plurality of bending grooves 601, and the two ends of the dust cover 6 are provided with bending limiting ribs 602. The design of the bending grooves 601 can improve the overall bending characteristics of the dust cover 6, and the design of the limiting ribs 602 can keep the position fixed after bending, thereby strengthening the bending deformation limiting effect of the dust cover 6, so that the dust cover 6 can be bent into different shapes according to actual needs.

[0025] In an embodiment of this utility model, the air intake pipe 5 includes an outer pipe 501 with heat insulation properties, an inner pipe 502 is fixedly disposed inside the outer pipe 501, and a heat insulation cavity 503 is formed between the outer pipe 501 and the inner pipe 502; the inner pipe 502 is made of PTFE pipe with a wall thickness of 1mm, the heat insulation layer of the outer pipe 501 has a wall thickness of 2mm, and the heat insulation cavity 503 formed in the middle can increase the heat transfer resistance, maintain the stability of the air temperature inside the inner pipe 502, and reduce the interference of the external environment.

[0026] In an embodiment of this utility model, an exhaust hole 703 is provided through the side of the box body 701 facing the silicone hose 702, and a movable sealing component 9 is sealed inside the exhaust hole 703; the exhaust hole 703 and the sealing component 9 cooperate to achieve an automatic opening state when the temperature and humidity detection box 7 is filled with air, so as to maintain the stability of the internal air.

[0027] In an embodiment of this utility model, the sealing component 9 includes a cross 901 fixed to the inner wall of the box 701. A limiting sleeve 902 is fixedly provided at the center of the cross 901 near the side of the box 701. A sealing plate 903 that fits against the inner wall of the vent 703 is fixedly connected to the end of the limiting sleeve 902. When the sealing plate 903 loses its compressive force, it can automatically spring back and reset by pulling the limiting sleeve 902, thus achieving the effect of automatic sealing.

[0028] In an embodiment of this utility model, a limiting rod 904 that fits against the inner wall of the limiting sleeve 902 is fixedly provided on the side of the cross 901, and a return spring 905 that is inserted and connected to the limiting rod 904 is fixedly provided on the side of the sealing plate 903; through cooperation, the sealing plate 903 can maintain a horizontal movement effect, is not easy to deviate, and improves the stability of sealing the exhaust hole 703.

[0029] Working Principle: This embodiment provides an automatic sensing device for detecting ambient temperature and humidity. First, by adjusting the height of the lifting frame 1, it can adapt to the detection needs of different environments. After the air pump 2 is started, the three-way solenoid valve 3 controls the opening and closing of the connection end, allowing the connecting pipes 4 at different port heights to collect ambient gas at the corresponding heights in sequence. The air inlet pipe 5 adopts an "outer pipe 501 + inner pipe 502 + heat insulation cavity 503" structure, which can isolate external temperature interference and avoid deviation in the temperature of the collected gas. Its flat round port design can increase the gas intake volume. At the same time, the end elastic dust cover 6 adapts to different environments through the deformation of the bending groove 601. With the support of the limiting rib 602, it can maintain the stability of the structure after bending deformation, so as to maintain airflow under a specific shape. When the gas collected by one side of the air inlet pipe 5 is pressurized by the air pump 2, it is delivered to the box 701 of the temperature and humidity detection box 7 through the silicone hose 702. The temperature and humidity sensor 8 makes full contact between the gas and the opposing surfaces inside the housing 701, directly detecting the gas temperature and humidity data to achieve automatic sensing and detection of ambient temperature and humidity. When there is too much gas inside the housing 701, the sealing plate 903 can be displaced, causing the exhaust port 703 to open, allowing excess air to escape and maintaining stable internal airflow. After the air pump 2 stops working, the air pressure inside the housing 701 decreases. Under the guidance and limitation of the limit rod 904 and the limit sleeve 902, the return spring 905 pushes the sealing plate 903 to reset, resealing the exhaust port 703 to prevent external impurities from entering the housing 701, protecting the temperature and humidity sensor 8, and preparing for the next test. In this way, temperature and humidity can be detected in environments at different heights sequentially, improving the accuracy of temperature detection at different heights under the same benchmark. Throughout the process, the three-way solenoid valve 3 can close the gas path to prevent dust or impurities from entering the gas system when not in a detection state, ensuring the accuracy of the device in the next use.
