Rapid and accurate detection of atmospheric humidity is of great significance for ensuring production safety, improving technological level and enhancing quality of life.
[0003] Traditional humidity detection devices mostly use passive sampling, which relies on the natural diffusion of air to the sensor's sensitive element for measurement. This method has problems such as slow response speed, great influence from ambient airflow, and significant measurement lag in static or low-flow air, making it difficult to meet the application requirements for real-time and rapid monitoring of humidity changes. Utility Model Content
[0004] The purpose of this invention is to provide a rapid atmospheric humidity detection device, which solves the problem that traditional humidity detection devices mostly adopt a passive sampling method, that is, rely on the natural diffusion of air to the sensor's sensitive element for measurement. This method has problems such as slow response speed, great influence from ambient airflow, and significant measurement lag in static or low-flow air, making it difficult to meet the application requirements for real-time and rapid monitoring of humidity changes.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a rapid atmospheric humidity detection device, including a housing, a display screen installed on the inner wall of the housing, an air inlet pipe installed on the left inner wall of the housing, an air outlet pipe installed on the right inner wall of the housing, and a detection component for detecting air humidity installed inside the housing. The detection end of the detection component is connected to the air inlet pipe and the air outlet pipe.
[0007] Furthermore, the detection component includes a gas channel tube, a humidity sensor is fixedly installed at the inner bottom of the gas channel tube, an inclined guide plate is fixedly installed at the inner bottom of the gas channel tube, a micro pump is installed on the inner wall of the housing, an input pipe is installed at the output end of the micro pump, and a connecting shell is installed on the upper surface of the gas channel tube.
[0008] Furthermore, the input pipe is connected to the connecting shell, the connecting shell is connected to the interior of the gas channel pipe, and the gas channel pipe is connected to the inlet pipe and the outlet pipe.
[0009] Furthermore, two staggered grooves are formed on the outer surface of both the air inlet pipe and the air outlet pipe, and an installation groove is formed inside both the air inlet pipe and the air outlet pipe. A first magnetic ring is fixedly installed on the inner wall of each installation groove.
[0010] Furthermore, each of the mounting slots is equipped with a dustproof plate, and a second magnetic ring is fixedly installed on the side of the dustproof plate near the first magnetic ring, and the second magnetic ring and the first magnetic ring are magnetically attracted to each other.
[0011] Furthermore, two protrusions are fixedly installed on each of the peripheral sides of the dustproof plate, and the protrusions are located inside the misalignment groove.
[0012] This utility model has the following beneficial effects:
[0013] (1) The present invention uses the airflow blown out by the micro pump to induce the Venturi effect through the setting of the inclined guide plate, thereby realizing negative pressure air intake without moving parts in the air intake pipe. This method is faster than simple natural diffusion sampling and more energy-efficient than direct negative pressure sampling because the main airflow simultaneously undertakes the dual functions of introduction and transportation, realizing rapid detection of atmospheric humidity.
[0014] (2) The dustproof plate at the air inlet of this utility model can prevent external dust from being directly sucked in, protect the internal cleanliness, and the magnetic fixing method makes the cleaning and replacement of the dustproof plate extremely simple and quick, greatly improving the user experience and equipment maintenance convenience.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-4 As shown, this utility model is a rapid atmospheric humidity detection device, including a housing 1, a display screen 2 installed on the inner wall of the housing 1, an air inlet pipe 4 installed on the left inner wall of the housing 1, an air outlet pipe 5 installed on the right inner wall of the housing 1, and a detection component 3 for detecting air humidity installed inside the housing 1. The detection end of the detection component 3 is connected to the air inlet pipe 4 and the air outlet pipe 5.
[0025] The detection component 3 includes a gas channel tube 301, a humidity sensor 302 is fixedly installed at the bottom inner side of the gas channel tube 301, an inclined guide plate 303 is fixedly installed at the bottom inner side of the gas channel tube 301, a micro pump 304 is installed on the inner wall of the housing 1, an input tube 305 is installed at the output end of the micro pump 304, and a connecting shell 306 is installed on the upper surface of the gas channel tube 301.
[0026] The input pipe 305 is connected to the connecting shell 306, the connecting shell 306 is connected to the interior of the gas channel pipe 301, and the gas channel pipe 301 is connected to the inlet pipe 4 and the outlet pipe 5.
[0027] Specifically, the micro pump 304 starts working, drawing in air from the surrounding area and blowing this pressurized airflow into a specific area within the gas channel pipe 301 through its output and input pipes 305. The high-speed airflow is guided and accelerated by the inclined guide plate 303. According to the Venturi effect in fluid mechanics, the static pressure decreases when the high-speed airflow passes through a narrow passage. This design creates a local negative pressure zone at the connection between the intake pipe 4 and the gas channel pipe 301. This negative pressure effect can actively and quickly draw the external air to be tested into the interior of the gas channel pipe 301 through the intake pipe 4. The drawn-in air immediately mixes with the main airflow blown out by the pump in the channel and flows together through the detection area of the humidity sensor 302. The humidity sensor quickly and in real time measures the humidity of the mixed airflow and transmits the signal to the display screen 2 for final display.
[0028] Two staggered grooves 6 are provided on the outer surface of the air inlet pipe 4 and the air outlet pipe 5. An installation groove 7 is provided inside the air inlet pipe 4 and the air outlet pipe 5. A first magnetic ring 8 is fixedly installed on the inner wall of the installation groove 7.
[0029] The interior of each mounting slot 7 is equipped with a dustproof plate 9. A second magnetic ring 10 is fixedly installed on the side of the dustproof plate 9 near the first magnetic ring 8. The second magnetic ring 10 and the first magnetic ring 8 are magnetically attracted to each other.
[0030] Two protrusions 11 are fixedly installed on each of the peripheral sides of the dustproof plate 9, and the protrusions 11 are located inside the misalignment groove 6.
[0031] Specifically, the dustproof plate 9 installed at the ports of the air inlet pipe 4 and the air outlet pipe 5 is fixed by the adsorption of the first magnetic ring 8 and the second magnetic ring 10, which can filter large particles of impurities. The design of the protrusion 11 and the misalignment groove 6 makes it easy to take out the dustproof plate 9 and disassemble it.
[0032] Working Principle: Upon startup, the micro pump 304 draws in air from the surrounding area and, through its output and input pipes 305, directs this pressurized airflow towards a specific area within the gas channel pipe 301. The high-speed airflow is guided and accelerated by the inclined guide plate 303. Based on the Venturi effect in fluid mechanics, the static pressure decreases when the high-speed airflow passes through a narrow passage. This design creates a local negative pressure zone at the connection between the inlet pipe 4 and the gas channel pipe 301. This negative pressure effect actively and quickly draws the ambient air to be measured into the gas channel pipe 301 through the inlet pipe 4. The drawn-in air immediately mixes with the main airflow from the pump within the channel and flows together through the detection area of the humidity sensor 302. The humidity sensor rapidly and in real-time measures the humidity of the mixed airflow and transmits the signal to the display screen 2. Finally, all air is discharged from the device through the outlet pipe 5. The dustproof plate 9 installed at the port is fixed by the first magnetic ring 8 and the second magnetic ring 10, which can filter large particles of impurities. The design of the protrusion 11 and the misalignment groove 6 makes it easy to pick up and disassemble the dustproof plate 9.
