Description
Technical field
Thermometry field is the utility model is related to, especially a kind of accurate wireless humiture probe.
Background technology
Cold chain refers to that some raw-food materials, the food by processing or semi-finished product, special biological products and medicine are passing through
After crossing purchase, processing, sterilizing, inactivation, during Product processing, storage, transport, distribution and retail, use, its links
All the time it is under specific low temperature environment necessary to product, reduces loss, prevent from polluting and go bad, ensures that product food is pacified
Entirely, bio-safety, the special supply chain system of drug safety.
In order to detect the humidity in air, the housing of wireless humiture probe is typically provided with through hole, so that air can
It is internal to enter humiture probe, but in the detection process of cold chain, the water in environment may enter wireless warm and humid from through hole
The inside of probe is spent, so as to cause Humidity Detection inaccurate, in some instances it may even be possible to damage the wiring board of wireless humiture probe.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of accurate wireless humiture probe, and it can be with
Humidity in accurate detection air, and can effectively prevent wireless humiture tip damage.
A kind of accurate wireless humiture probe, including housing and master control borad in housing and supplied to the master control borad
The power supply of electricity, the master control borad are provided with temperature and humidity measurement circuit, processing unit and wireless transport module, and the master control borad is provided with
Temperature and Humidity element, the housing are provided with through hole, and the through hole corresponds to the Temperature and Humidity element and set, the through hole
Place is provided with and is available for the waterproof layer that air passes through.
Further, the area of the through hole is 0.1cm2-1cm2.
Further, the waterproof layer includes PP spun-bonded non-woven fabrics layer and PE gas permeable polymer films.
Further, the housing includes upper shell and lower house, and the through hole is located on upper shell, the upper shell and
Lower house is connected by screw.
Using the above method, the utility model has following technique effect：
1. through hole corresponds to the Temperature and Humidity element and set, the through hole is provided with and is available for the waterproof layer that air passes through,
So that the aqueous vapor in air can pass through from waterproof layer so that detecting element can detect the humidity in air, and ring
Water in border can not enter the inside that wireless humiture is popped one's head in by waterproof layer, prevent water from directly contacting detecting element and causing to detect
Precise decreasing, and can effectively prevent wireless humiture tip damage.
2. the area of the through hole is 0.1cm2-1cm2.So as on the basis of accuracy of detection is ensured, effectively reduction into
This.If via area is less than 0.1cm2, the moisture in environment possibly can not be transmitted swimmingly to detecting element, if through hole
Area is more than 1cm2, then needs larger waterproof layer, so as to increase cost.
3. waterproof layer includes PP spun-bonded non-woven fabrics layer and PE gas permeable polymer films.It is wireless not only effectively to prevent that aqueous water from entering
Humiture probe is internal, accurately detects humidity, and has preferable intensity, prevents waterproof layer from damaging.
Brief description of the drawings
Fig. 1 is the structural representation of embodiment one.
Fig. 2 is the front view of embodiment one.
Fig. 3 is the waterproof layer structure schematic diagram of embodiment one.
Housing 1, upper shell 2, lower house 3,21, groove 22 of releasing the button, through hole 23, button cell 4, master control borad 5, monolithic
Machine 51, detecting element 54, waterproof layer 6.
Specific embodiment
The technical scheme of the utility model embodiment is explained with reference to the accompanying drawing of the utility model embodiment and
Illustrate, but following embodiments are only preferred embodiment of the present utility model, and it is not all.Based on the embodiment in embodiment,
Those skilled in the art obtain other embodiment on the premise of creative work is not made, and belong to of the present utility model
Protection domain.
Embodiment one：
As shown in figure 1, present embodiments provide a kind of accurate wireless humiture probe, it includes housing 1, housing 1 by
Upper shell 2 and lower house 3 form, and are fixedly mounted between upper shell 2 and lower house 3 by screw and nut, the outer surface of upper shell 2
It is installed with and releases the button 21, releasing the button 21 is embedded in push-button recess 22, and push-button recess 22 is cylinder, and cylinder
One end is run through the inwall of upper shell 2 and is fixedly mounted on inwall, the electricity powered in housing 1 provided with master control borad 5 and to master control borad 5
Source, power supply is button cell 4 in the present embodiment, and the master control borad 5 is provided with temperature measuring circuit, processing unit and wireless
Transport module, the processing unit include single-chip microcomputer 51, and in the present embodiment, the processing unit is by the number of temperature measuring circuit
Transmitted according to after processing by wireless transport module, the master control borad 51 is provided with Temperature and Humidity element 54, is set on the housing
Have through hole 23, the area of the through hole 23 is 0.5cm2, certainly, the area of through hole 23 be not limited to 0.5cm2 or
0.1cm2,0.3cm2,0.8cm2,1cm2, so as on the basis of accuracy of detection is ensured, effectively reduce cost.If through-hole face
Product is less than 0.1cm2, then the moisture in environment possibly can not be transmitted swimmingly to detecting element, if via area is more than 1cm2,
Larger waterproof layer is then needed, so as to increase cost.The corresponding Temperature and Humidity element 54 of the through hole 23 is set, described logical
It is provided with hole and is available for the waterproof layer 6 that air passes through.
The waterproof layer 6 includes PP spun-bonded non-woven fabrics layer and PE gas permeable polymer films.Detected in the environment of cold chain
When, if the water in cold chain environment instills through hole 23, water is difficult that therefore, aqueous water can not pass through by PE gas permeable polymer films
Waterproof layer enters the inside of wireless humiture probe, prevents water from directly contacting detecting element and causing accuracy of detection to decline, and can
Effectively to prevent wireless humiture tip damage.And the aqueous vapor in air can pass through from waterproof layer so that detecting element can be with
Detect the humidity in air.PP spun-bonded non-woven fabrics layers are arranged on the outside or both sides of PE gas permeable polymer films, so as to effectively increase
Add the intensity of waterproof layer, prevent waterproof layer from damaging.
As described above, preferred embodiment only of the present utility model, is not used for limiting reality of the present utility model
