[0028] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0029] Example 1:

[0030] This embodiment provides a data collector, including:

[0031] The plug-in terminal 2 is provided at one end of the collector body 1 and includes a plug-in cavity 3;

[0032] Humidity sensor 4, humidity sensor 4 is arranged on the inner wall of plug cavity 3;

[0033] The vent valve 5 is provided on the collector body 1 and connects the plug cavity 3 with the interior of the collector body 1;

[0034] A ventilation fan 6 is provided inside the collector body 1 and an output end of the ventilation fan 6 is connected to the ventilation valve 5;

[0035] The humidity sensor 4 controls the opening and closing of the ventilation valve 5 and the ventilation fan 6 .

[0036] The housing of the collector body 1 is generally a closed structure. Internal cushioning material can be installed to reduce the impact of vibration on internal components. The housing materials and advantages of the collector body 1 include: Metal: Aluminum alloy: Lightweight and corrosion-resistant, suitable for most environments, and provides good heat dissipation. Stainless steel: Highly corrosion-resistant, suitable for extreme environments, but heavier. Steel: Strong and durable, commonly used in industrial applications, but may require rust-proofing. Plastic: ABS (Acrylonitrile-Butadiene-Styrene): Impact-resistant, suitable for lightweight designs, commonly used in indoor equipment. Polycarbonate: High strength and impact resistance, suitable for applications requiring high durability. Polypropylene: Chemically resistant, suitable for chemical or humid environments. Composite materials: Carbon fiber: Extremely strong and lightweight, commonly used in high-end or specialty applications, but at a higher cost. Fiberglass-reinforced plastic (FRP): Combines the lightness of plastic with the strength of metal, suitable for applications requiring corrosion and impact resistance. Other components and modules are located within the housing of the collector body 1, which are prior art and will not be discussed in detail in this application.

[0037] The shape of the plug-in end 2 is set according to the shape of the interface, which is generally a straight line, and a plug-in cavity 3 is opened on the end face of the plug-in end 2. A needle-like structure for signal connection is set in the plug-in cavity 3. The needle-like structure is connected to the internal components or modules of the collector body 1. This is a prior art and will not be described in detail. A humidity sensor 4 is provided at the bottom of the plug-in cavity 3, which is flat or array-arranged. A hole is provided on the humidity sensor 4 for passing through the needle-like structure to avoid collision interference, and the needle-like structure can make the humidity sensor 4 structure more stable. The humidity sensor 4 can be arranged in an array to measure the humidity in a larger range and reduce detection blind spots. The humidity sensor 4 can be a surface tension humidity sensor 4 or a resistive humidity sensor 4. The surface tension humidity sensor 4 includes a droplet or a film. Changes in humidity will cause changes in the shape of the droplet or film. The humidity level can be determined by measuring the change in shape. The resistive humidity sensor 4 uses a humidity-sensitive material, such as a polymer or ceramic, as a resistance element. Humidity changes will affect the resistance value of the material. The humidity level can be determined by measuring the change in resistance, and the signal of the humidity sensor 4 is transmitted to the control circuit. The control circuit transmits the signal to the drive device of the ventilation valve 5 and the ventilation fan 6, and controls the opening and closing of the ventilation valve 5 and the ventilation fan 6 through the humidity sensor 4.

[0038] Working principle:

[0039] When the air humidity in the plug-in cavity 3 exceeds the warning line, the humidity sensor 4 sends a signal to the control system, which then controls the ventilation valve 5 and the ventilation fan 6 to open. Since heat is generated inside the collector body 1, the air containing heat is transmitted to the plug-in cavity 3 through the ventilation fan 6 and the ventilation valve 5, thereby increasing the temperature inside the plug-in cavity 3, so that the moisture evaporates and flows out through the gap. When the air humidity in the plug-in cavity 3 drops below the warning line, the ventilation fan 6 and the ventilation valve 5 are closed to prevent moisture from entering the interior of the collector body 1.

[0040] The above structure can prevent the humidity in the plug-in cavity 3 from being too high, which may cause the connection between the data collector plug-in terminal 2 and the interface to fail.

[0041] Example 2:

[0042] This embodiment provides a data collector, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0043] Also includes:

[0044] The air outlet channel 7 connects the outside of the collector body 1 and the inside of the plug-in cavity 3, and a baffle 8 is provided at the outer end of the air outlet channel 7. The baffle 8 is formed on the surface of the collector body 1 and will open when subjected to pressure.

[0045] The air outlet channel 7 is used to connect the outside of the collector body 1 and the plug-in cavity 3. Preferably, the outer end of the air outlet channel 7 is set on the side outer wall of the collector body 1, and a baffle 8 is provided at the outer end of the air outlet channel 7. The baffle 8 is a thin sheet structure, and the outer side of the baffle 8 is in contact with the inner wall of the outlet channel. A rubber part can be added to the outer side of the baffle 8 to increase the sealing performance. When the ventilation valve 5 and the ventilation fan 6 are started, the air pressure in the plug-in cavity 3 will increase, and the baffle 8 will be pushed open, releasing the air containing water vapor through the air outlet pipe, so that the air flows and the dehumidification efficiency is higher. When dehumidification is not required, the baffle 8 blocks the air outlet channel 7 to prevent foreign matter, water or dust from entering the plug-in cavity 3.

[0046] Example 3:

[0047] This embodiment provides a data collector, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0048] One end of the air outlet channel 7 in the plug-in cavity 3 and the vent valve 5 are respectively arranged at two ends of the plug-in cavity 3 .

[0049] By arranging one end of the air outlet channel 7 in the plug-in cavity 3 and the vent valve 5 at the two ends of the bottom of the plug-in cavity 3 respectively, the flow range of the plug-in cavity 3 is increased, dead corners of stagnant flow are prevented, and the effective dehumidification area and efficiency are increased.

[0050] Example 4:

[0051] This embodiment provides a data collector, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0052] An elastic deformation sheet 9 is further provided between the baffle 8 and the surface of the collector body 1 .

[0053] The elastic deformation sheet 9 is an integral structure extending from the edge of the baffle 8 toward the periphery. The elastic deformation sheet 9 extends the deformation area of ​​the baffle 8, so that when the curvature of the baffle 8 is the same, the opening of the baffle 8 is larger and deformation due to excessive bending curvature is less likely to occur.

[0054] Example 5:

[0055] This embodiment provides a data collector, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0056] The vent valve 5 is a miniature ball valve.

[0057] The structure of the vent valve 5 is a ball valve structure. If a ball valve of this size is not available on the market, the ball valve can be made by 3D printing. The ball valve structure is easier to print and install.

[0058] Example 6:

[0059] This embodiment provides a data collector, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0060] Also includes:

[0061] The temperature sensor is arranged in the collector body 1 and controls the opening and closing of the ventilation valve 5 and the ventilation fan 6.

[0062] A temperature sensor is provided in the collector body 1. The temperature sensor is a device that can sense temperature and convert it into a usable output signal. The working principle is mainly based on the principles of thermoelectric effect, resistance effect, thermistor effect, thermocouple effect, etc., and the temperature signal is converted into an electrical signal. When the temperature is too high and reaches a dangerous value, the ventilation valve 5 and the ventilation fan 6 are activated to release the hot air inside the collector body 1 through the plug-in cavity 3 and the air outlet channel 7 to the outside to achieve cooling.

[0063] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific embodiments. The above-mentioned specific embodiments are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which fall within the scope of protection of this application.
