Description

Technical Field

[0001] The utility model relates to the technical field of humidity detection, in particular to a combined humidity detection device. Background Art

[0002] Humidity is defined as a physical quantity that indicates the dryness of the atmosphere. That is, the less water vapor contained in a certain volume of air at a certain temperature, the drier the air is; the more water vapor, the more humid the air is. Traditional humidity detection sensors include resistive or capacitive humidity detection sensors. For example, humidity sensors are the simplest humidity detection sensors. Humidity sensors mainly include resistive and capacitive humidity sensors. The characteristic of resistive humidity sensors is that a film made of humidity-sensitive materials is covered on the substrate. When water vapor in the air is adsorbed on the humidity-sensitive materials, the resistivity and resistance value of the resistive humidity sensors change. This characteristic can be used to measure humidity.

[0003] The inventors have found through research that the application range of the existing humidity detection devices is relatively small. Therefore, when workers conduct measurements outdoors, they need to carry a variety of measurement devices, which increases the burden on the workers. Utility Model Content

Under the action of the heat dissipation hole 13, the connection between the plug 9 and the jack 7 can be dissipated, and a display 10 electrically connected to the main board 3 is provided at the front end of the shell 1, and a button 11 electrically connected to the main board 3 is provided on the front wall of the shell 1, and the button 11 is used to select the needle probe 2 or the spherical microwave generator 6 to work.

[0030] The working principle of a combined humidity detection device is as follows: when measuring different objects to be tested, it is possible to select whether to use a needle probe 2 or a spherical microwave generator 6 for detection according to the characteristics of the objects to be tested, that is: when the surface of the object to be tested can be punctured, first insert the plug 9 into the jack 7, then press the button 11, select the detection mode, then the needle probe 2 can be used, at this time, hold the housing 201, use the pin 202 to puncture the surface of the object to be tested, so that the humidity of the object to be tested can be detected through resistance and the data can be sent to the main board 3 through the wire 8; when the object to be tested is in a small space and its surface is not allowed to be punctured, pull the plug 9 out of the jack 7, then press the button 11, and select the detection mode. 1. The spherical microwave generator 6 is extended into the space where the object to be tested is located through the connecting rod 5. At this time, microwaves are generated by the spherical microwave generator 6. Since microwaves are absorbed when passing through the object, the microwave energy will be attenuated. Moreover, the greater the moisture content of the object, the greater the attenuation of the microwave energy. Therefore, the humidity can be detected by the attenuation of the microwave. The humidity value finally measured is displayed on the display 10, which is convenient for the staff to observe. The practicality of the device is improved by the mutual cooperation between the needle probe 2 and the spherical microwave generator 6. By making the length of the wire 8 1 meter, the display 10 can be convenient for the user to observe during the detection of the pin 202, which plays a role in improving the practicality of the device.

[0031] The beneficial effects of the combined humidity detection device provided by this embodiment include: the needle probe 2 can be disassembled through the cooperation of the jack 7 and the plug 9, so that the entire device can be applied to different scenarios, expanding the application range of the device.

A battery 16 is detachably installed in the shell 1. When the power of the battery 16 is exhausted, the device can continue to be used by replacing the battery 16. A back cover 17 that cooperates with the battery 16 is detachably installed on the outer wall of the shell 1, and an elastic cover 15 is fixedly installed on the shell 201, and the wire 8 passes through the elastic cover 15.

[0034] The working principle of a combined humidity detection device is: when the wire 8 shakes, the elastic sleeve 15 can reduce the shaking amplitude of the wire 8, thereby preventing the wire 8 from directly contacting the shell 201, reducing the degree of wear on the outer wall of the wire 8, and when the device accidentally falls to the ground, the protective sleeve 12 made of elastic material can play a buffering role, thereby reducing the impact force on the device.
