Abstract
The invention discloses a mismeasurement preventing device for a humidity sensor. An air jacket is sleeved around the humidity sensor; one end of the air jacket is provided with an air inlet connected with an air source, and the other end of the air jacket is provided with an air outlet; and a channel enabling an air flow to flow towards a probe of the humidity sensor after flowing out of the air outlet is arranged between the air inlet and the air outlet. The mismeasurement preventing device for the humidity sensor has the advantages that the air source can be opened to enable gas to be blown towards the probe through the channel when the humidity measured by the humidity sensor is equal to 100%, water vapor can be evaporated after the gas is blown if water is attached to the humidity sensor, and finally, the humidity value measured by the humidity sensor accords with the actual condition, so that humidity mismeasurement caused by water attachment can be avoided.
Description
Technical field
The present invention relates to a kind of humidity sensor technical field, more precisely a kind of humidity sensor Anti-error device.
Background technology
There is the place of requirement at some to humidity, often need humidity sensor be set, the moisture signal obtained by humidity sensor and controlling accordingly.But in the place that some humidity are larger, the probe of humidity sensor easily hangs water, and once hang water, namely humidity sensor judges that on-the-spot humidity is 100%, and in fact humidity does not reach 100%, even if humidity reduced afterwards, probe still hangs water, then this humidity sensor hanging water detects and the humidity shown or 100%, so just occurs the error-detecting to humidity, just loses meaning to the original intention of carrying out relevant control according to humidity.
As can be seen here, how to arrange a device, can prevent humidity sensor from missing measuring moisture because hanging water, this is the current technical issues that need to address in this area.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of humidity sensor Anti-error device, can preventing humidity sensor from missing measuring moisture because hanging water.
For solving above technical matters, a kind of humidity sensor Anti-error device of the present invention, comprise the air-casing be set in around humidity sensor, on described air-casing, one end is provided with the air intake opening be connected with source of the gas, the described air-casing other end is provided with gas outlet, is provided with and makes gas flow out the passage of gas outlet after-blow to humidity sensor probe between air intake opening and gas outlet.
Preferably, it is hollow structure between the madial wall of described air-casing and lateral wall, on an end face of air-casing, be connected by web joint between madial wall with lateral wall, described air intake opening is formed on described web joint, on the other end of air-casing, the space between madial wall and lateral wall is as gas outlet.
Preferably, the madial wall of described air-casing and lateral wall are cone cylinder body shape or prismoid shape.
Preferably, described air intake opening is connected by tracheae with between source of the gas.
Preferably, described tracheae is provided with operation valve.
Preferably, also comprise a controller, when to record current humidity be 100% to humidity sensor, described controller sends start signal to operation valve and makes operation valve predetermined hold-time section in the on state.
Preferably, after operation valve opens predetermined hold-time section, when the current humidity that humidity sensor records is still 100%, namely described controller then sends start signal to operation valve every Preset Time.
Preferably, described air intake opening is multiple.
Preferably, described gas outlet is multiple, arranges around humidity sensor probe.
Preferably, described gas outlet is ring-type, arranges around humidity sensor probe.
Compared with prior art, humidity sensor Anti-error device of the present invention, comprise the air-casing be set in around humidity sensor, on described air-casing, one end is provided with the air intake opening be connected with source of the gas, the described air-casing other end is provided with gas outlet, be provided with between air intake opening and gas outlet and make gas flow out the passage of gas outlet after-blow to humidity sensor probe, thus, when to record humidity be 100% to humidity sensor, can open source of the gas makes gas blow to humidity sensor probe via passage, if to cause because hanging water, after then blowing, can water evaporation, the humidity finally making humidity sensor record is realistic, the mistake to humidity produced because hanging water so just can be avoided to survey.

Embodiment
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
See Fig. 1, Fig. 2, the humidity sensor Anti-error device in the present embodiment, comprise the air-casing 2 around the probe 11 being set in humidity sensor 1, this air-casing 2 does not contact with the miscellaneous part of probe 11 and humidity sensor.Air-casing 2 comprises lateral wall 21 and madial wall 22, is hollow structure between lateral wall 21 and madial wall 22, and lateral wall 21 and madial wall 22 are cone cylinder body shape, and one end that air-casing bore is little is positioned at below, arranges near the humidity inductive district 11a of probe; On air-casing one end face, be connected between lateral wall with madial wall by a junction 23, connecting portion 23 is provided with two air intake opening 2a; On air-casing other end, be not connected between lateral wall with madial wall, space therebetween, as gas outlet 2b, forms the gas passage of inclination between air intake opening and gas outlet; Air intake opening 2a is connected with compressed gas source by tracheae 3.Operation valve 4 is provided with in tracheae 3.The structural design that air-casing is such, makes the humidity inductive district 11a that can be blowed to probe by gas outlet gas out, is dried up by the water herein hung.
Humidity sensor Anti-error device in the present embodiment, also be provided with controller (not shown), when humidity sensor detects that humidity is 100%, controller sends steering order, operation valve is opened, compressed gas blows to probe via air intake opening, gas passage, gas outlet, blows probe after 10 seconds, as humidity still shows 100%, then illustrate that the humidity of 100% does not cause owing to hanging water, if and after having blown compressed gas, humidity changes, then illustrate because extension water causes.In 10 seconds that open compression air-blowing probe, do not carry out with the relevant control of humidity.After having blown compressed gas, if it is 100% that humidity shows always, then carrying out repetition blowing operation every 2 minutes, avoiding producing survey by mistake because hanging water.
Above to invention has been detailed introduction, applying specific case and setting forth principle of the present invention and embodiment in literary composition, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
