The air moisture sampling device is composed of a moisture sensitive element, an outer cover for the moisture sensitive element, an air pump, an air pump driving motor, an electronic time switch and motor power supply. The air moisture sampling device adopts the method of electronic controlled time ventilation to increase the amount of the factors of moisture signals collected by the moisture sensitive element and extend the collecting scope of the moisture signals for improving the precision of the moisture sensor, improving the stability of the moisture sensor and improving the cost performance of the moisture sensor taking the moisture sensitive element as the center. The utility model creates a good condition for the electromechanical integration controlled by moisture measurement.
Description
The utility model relates to measurement, the instrument of the air humidity that controls environment or equipment.
Air is ceaselessly to flow in environment space, and for certain volume space, the air humidity of the unitary space of each diverse location has discreteness and dynamic character in the space.As air humidity (the being called for short humidity down) value that will measure this space integral body more exactly, then must gather the moisture signal factor in this space as much as possible, and these moisture signal factors are taken from all positions in this space as far as possible, the mean value that has only all moisture signal factors in this space could the correct humidity of expressing this space integral body.
Humidity measurement and control instrument or equipment are when using humidity-sensitive element to carry out the humidity sampling at present, only be exposed to humidity-sensitive element in the air simply, the not measure of auxiliary sampling, so the method for sampling make humidity-sensitive element adopt the moisture signal factor be confined to limited small space around the humidity-sensitive element; And, make the ambient humidity, light and temperature signal factor that transient changing take place thereupon because humidity-sensitive element surrounding air flows to and the variation of flow.The humidity value that records thus has locality and randomness, and its precision is difficult coincide with the meteorological humidity instrument of standard.
For solving above contradiction, the utility model provides a kind of as preceding page or leaf claims described air humidity sampling apparatus.
The method that this air humidity sampling apparatus solves above contradiction is: by the regularly forced ventilation of Electronic Control air pump, allow be sampled air and flow through the humidity-sensitive element surface with certain orientation, certain flow, certain speed; The humidity undesired signal of getting rid of sampling apparatus xsect all directions by the humidity-sensitive element outer cover; By regularly forced ventilation of air pump, impel the surrounding space air to mix trend naturally evenly.After taking above measure, humidity-sensitive element just can obtain the moisture signal factor of surrounding space more, comparatively fast, more equably, through the accumulation mean effort of certain hour humidity-sensitive element to moisture signal, the moisture signal that presents on humidity-sensitive element at last promptly approaches the humidity mean value of certain volume space on every side.Therefore, the moisture signal that records of this sampling apparatus can the correct face of land reach the humidity of certain volume space integral body.
Below in conjunction with the description of drawings structure of the present utility model and the course of work.
Shown in Figure of description, at tubular case of humidity-sensitive element (1) outside suit is humidity-sensitive element outer cover (4), its first effect be certain air pressure arranged around when sampling keeps humidity-sensitive element be sampled air uniformly, its second effect is a humidity undesired signal of getting rid of the sudden change that sampling apparatus xsect all directions come.Humidity-sensitive element (1) and humidity-sensitive element outer cover (4) are installed in the front end of the air inlet (9) of air pump (2), are sampled air and are following following path flows to guarantee when air pump (2) turns round, to force; Air flows into from humidity-sensitive element outer cover air inlet (8), flows into air pump air inlet (9) through humidity-sensitive element (1) back, again outside air pump air outlet (10) discharger.
Shown in Figure of description, installing air pump driving power (3) is as the power of air pump below air pump (2).Air pump drive motor (3) has been connected in series electric timing switch (5) by motor power (6) power supply in supply line, be used for controlling the air pump drive motor and do regularly gap running.Gap running period is the air humidity sampling period, regulates electric timing switch (5) relevant elements value and can set up the humidity sampling period.
This device course of work is as follows: according to ambient humidity situation of change and time constant that electric timing switch (5) is regulated in the requirement of sampling precision, promptly regulate the humidity sampling period.Power turn-on master switch (11), sampling apparatus is started working, air pump drive motor (3) running, air pump (2) forced ventilation.Make to be sampled air and to flow into from humidity-sensitive element outer cover air inlet (8), through flowing into air pump air inlet (9) again behind humidity-sensitive element (1) surface, outside air pump air outlet (10) discharger with certain flow, certain speed.After obtaining moisture signal, humidity-sensitive element (1) transfers electric signal to, delivering to device outer signal processing system, air pump drive motor by humidity-sensitive element signal transmssion line (7) is controlled by electric timing switch (5) working time, operation a period of time promptly stops, stopping a period of time reruning the above course of work of going round and beginning again.
The Practical significance of this sampling apparatus: increase the quantity that humidity-sensitive element is gathered the moisture signal factor by the method that adopts Electronic Control regularly to ventilate, the acquisition range of expansion moisture signal, improve the precision of humidity sensor, improve the stability of humidity sensor, raising is the ratio of performance to price of the humidity sensor at center with the humidity-sensitive element, for the electromechanical integration of moisture measurement control has been created good condition.
