Detailed Description
The present invention will be described in further detail with reference to examples, which are illustrative of the present invention and are not to be construed as being limited thereto.
The first embodiment is as follows:
a sealable gas detection apparatus, comprising a detection mechanism and a sealing mechanism, the detection mechanism being as shown in fig. 1 and 2, and comprising:
a gas chamber 1, a gas sensor 2 positioned in the gas chamber, a gas inlet 3, a gas outlet 4, wherein, the air inlet channel 31 is used for communicating the air chamber 1 with the air inlet 3; a gas guiding device 5 which is communicated with the air chamber and controls the exchange of the internal gas and the external gas, and an exhaust passage 41 which is communicated with the gas guiding device 5 and the exhaust port 4. A filtering structure is arranged at the joint of the air inlet (3) and the air inlet channel (31).
According to different size requirements during actual product production, in order to enable the gas sensor 2 to detect the gas to be detected in the gas chamber 1, a hole for a sensing probe to extend into and be exposed in is formed in one side of the outer surface of the gas chamber, the gas chamber can also be designed into a cavity formed by matching a back plate 11 and a cover shell 12, a circuit board where the gas sensor 2 is located serves as the back plate 11 of the gas chamber, and the cover shell 12 of the gas chamber covers a part of the circuit board with the gas sensor to jointly form the gas chamber.
As shown in fig. 1, the air guiding device 5 includes a fan 51 and a baffle 52 for guiding the direction of the exhaust air, especially when a vortex fan is selected, a part of the vortex fan itself has a baffle for guiding the direction of the exhaust air, so that air can be discharged from one side and air can be discharged from the other side, and the exhaust channel 41 needs to be connected to the air outlet side of the vortex fan.
In order to prevent some impurities from being sucked into the air chamber to damage internal equipment or influence the detection result, a filter screen or a hydrophobic membrane (not shown in the filter structure diagram) is arranged at the joint of the air inlet 3 and the air inlet channel 31 and used for filtering non-gaseous impurities.
In order to ensure that the gas entering the gas chamber can be discharged quickly and prevent the gas residue from influencing the subsequent detection result, the gas flow area of the exhaust passage 41 is larger than or equal to that of the gas inlet passage 31.
In order to further accelerate the exhaust speed, an exhaust channel and an exhaust port can be respectively arranged at the two sides of the air chamber 1; in order to balance the pressure, the exhaust passages and the exhaust ports may be symmetrically distributed along the central axis of the gas guiding device 5 (two exhaust passages 41 are shown in fig. 1, and one exhaust port is not shown due to shielding).
Because turbofan self is non-confined, can bring the gas chamber into with the inside gas promptly of detection mechanism during its operation, if the detection mechanism is inside to be totally enclosed, there is certain probability can form gaseous vortex, lead to existing gas in the inside cavity of detection mechanism and the outside gas that gets into through inlet channel to be rotatory in vortex fan department always, form the unable discharge of negative pressure, influence the testing result, can set up inside and outside through-hole 6 of a plurality of communicationss device this moment on detection mechanism, be used for balanced negative pressure, the through-hole also can be used for the interior circuit heat dissipation of detection mechanism simultaneously. The sealing performance of the vortex fan can be modified by other means to solve the above problems.
In order to further prevent to form the gaseous vortex in the air chamber, set up slope guide table 13 in the one side of air chamber intercommunication gaseous guiding device and the opposite side that keeps away from gaseous guiding device both links up the department, prevent because there is the difference in height in air chamber both sides to form perpendicular ladder and make gaseous and strike perpendicular ladder bounce-back and come and go and form gaseous vortex when getting into air chamber one side and circulating to one side of intercommunication gaseous guiding device by inlet channel. When the height difference does not exist at the joint of the air chamber and the air guide device, the slope guide platform 13 is not required to be arranged.
If the device is used outdoors and may suffer from rainy or windy weather, the gas guiding device 5 is arranged at the upper side of the air chamber 1, the exhaust channel 41 and/or the air inlet channel 31 is arranged in a downward-trending gooseneck shape, and the exhaust port 4 is lower than the communication part of the gas guiding device 5 and the exhaust channel 41; the rainwater in the side direction can be prevented from being poured into the air chamber, and simultaneously, a part of wind and foreign matters carried in the wind can be shielded from blowing in, wherein the air inlet 3 is positioned below the air chamber 1, so that the rainwater is further prevented from entering the air chamber when raining; the gas enters from the gas inlet and reaches the gas chamber through the gas inlet channel, and then is guided into the gas exhaust channel through the gas guiding device and then is exhausted from the gas exhaust port. To further prevent rain water from entering the device, a through hole should also be provided below the device; meanwhile, the exhaust port 4 may be formed in a honeycomb shape or a filter screen may be additionally provided at the exhaust port 4 to further prevent foreign matters from being blown into the apparatus by wind.
The air guiding device can also be a common fan, a piezoelectric fan, an air pump, a blower or other mechanisms capable of sucking and discharging air out of the device, and the aim of the invention can be achieved only by adjusting the position of the air guiding device in the air chamber and the relative positions of the air guiding device and the air inlet channel and the air outlet channel according to the air guiding direction of the air guiding device or adding a guiding baffle.
In order to realize the functions of electronic components such as sensors, the internal structure of the invention necessarily comprises a control circuit and a power supply device (not shown in the figure), wherein the control circuit is used for controlling the gas sensor 2, the gas guiding device 5 and other electronic components to work, and the power supply device is used for supplying power to the electronic components of the device.
Although the casing of the detecting mechanism in fig. 1 is circular, in practical application, it can be designed into polygon, irregular shape or cartoon shape.
Example two:
the difference between the present embodiment and the first embodiment is that the present embodiment further includes a sealing mechanism, which can control the air inlet, the air outlet, or the through hole of the detection mechanism to be in a sealed or open state, and the sealing mechanism is activated when water proofing is required or the gas sensor needs to be operated in a sealed gas environment.
A sealing mechanism as shown in fig. 3 comprises a thin cover 301 and a rotating shaft 302, the thin cover is connected with a detection mechanism housing through a horizontal or vertical rotating shaft and rotates relative to the housing for opening or closing an air inlet, an air outlet or a through hole, and the detection mechanism is square in the figure.
Another kind of sealing mechanism, including set up the spout on the detection mechanism shell inside wall, be provided with the baffle in the spout, be provided with the fixture block on the baffle, set up the draw-in groove (be about to gas vent and/or air inlet and/or through-hole setting on detection mechanism shell lateral wall and be the trough-shaped) on the detection mechanism shell lateral wall, the fixture block card is gone into the draw-in groove and can slide in it to make the baffle slide in the spout, realize sealed or open detection mechanism.
As shown in fig. 4, when the detecting mechanism is circular, an annular sealing mechanism 7 can be disposed outside the detecting mechanism, the sealing mechanism can rotate relative to the detecting mechanism housing, an opening 711 is disposed at a position of the sealing mechanism relative to the air inlet, the air outlet or the through hole of the detecting mechanism, and when the sealing mechanism rotates to a corresponding position, the opening just coincides with or is staggered with the position of the air inlet, the air outlet or the through hole, so as to realize sealing or opening of the detecting mechanism.
In order to strengthen the water resistance, a waterproof coating or a sealing ring can be additionally arranged at the matching part of the sealing mechanism and the detection mechanism.
Example three:
the difference between this embodiment and the second embodiment is that the sealable gas detection apparatus further includes a motor, and a control circuit controls the operation of the motor to automatically control the opening and closing of the sealing mechanism by a program, so that the sealing mechanism and the detection mechanism can move relative to each other to seal or open the detection mechanism.
The sealable gas detection device is internally provided with a transmission mechanism which enables the motor to be matched with each sealing structure, and the transmission mechanism comprises but is not limited to conventional transmission mechanisms such as gears, cams, belts and the like.
When the sealing mechanism 7 is applied to the annular sealing mechanism 7 in the second embodiment, the motor 8 is fixedly connected with the detection mechanism and can be arranged inside the detection mechanism, for example, as shown in fig. 5, a motor gear 81 is arranged on the motor 8, the motor gear 81 extends out of the detection mechanism, a meshed tooth 82 matched with the motor gear is arranged on the lower side of the inner wall of the sealing mechanism in fig. 5, the motor gear is controlled to drive the sealing mechanism to rotate relative to the detection mechanism, and automatic sealing or opening of the detection mechanism is realized.
Example four:
as shown in fig. 6, a gas detection method includes the steps of:
presetting gas detection triggering conditions and stopping conditions;
presetting an abnormal alarm triggering condition and a releasing condition;
presetting the length of time for exhausting residual gas;
when gas detection is triggered, a gas sensor and a gas guide device are started;
if the abnormal alarm is not triggered during the operation period from the single detection triggering condition to the stopping condition, the gas sensor and the gas guiding device are closed when the gas detection is stopped;
if an abnormal alarm is triggered during the operation period after the gas detection is triggered, the gas sensor is closed after the abnormal alarm removing condition is reached and the gas detection stopping condition is reached, and the gas guiding device is closed after the preset residual gas discharging time length is passed.
Specific examples of applications are:
setting a gas detection trigger condition as a periodic time node (triggered once every 2 hours), and enabling a stop condition to reach a preset time length (30 minutes);
setting an abnormal alarm triggering condition as detecting that a certain target gas (the first target gas is CO) exists and/or the certain target gas (the second target gas is formaldehyde) reaches a certain concentration;
setting an abnormal alarm triggering condition to detect the existence of CO or the concentration of formaldehyde exceeding 0.065ppm, and releasing an alarm when the concentration of carbon monoxide is reduced to no detection response and the concentration of formaldehyde is lower than 0.065 ppm; the length of the residual gas discharge time is 2 minutes;
there may be logic associated between the gas detection stop condition and the abnormal alarm release condition, that is, if an abnormal alarm is triggered during the detection period, the detection is stopped after the abnormal alarm release condition is determined.
After the current gas detection triggering condition starts, assuming that CO is detected in the 25 th minute, an alarm is given, but no response is given in 5 minutes, at this time, a gas detection stopping condition of 30 minutes has been reached, but the abnormal alarm is not released, the gas sensor and the gas guiding device will continue to work, and after the alarm continues for 3 minutes, someone checks and ventilates to dissipate the CO, and the alarm is released, and meanwhile, the gas detection stopping condition is also reached, the gas sensor is closed first, and after 2 minutes of exhaust time, the CO which possibly remains in the gas chamber and cannot be detected by the gas sensor is exhausted (if the gas sensor which needs to be heated is used, the heat dissipation is equivalent to 2 minutes), and the gas guiding device is closed.
Example five:
the difference between the embodiment and the fourth embodiment is that the detection mechanism is opened before the gas guide device is opened, so that the gas to be detected can enter the gas chamber; after the gas diversion device is closed, the detection mechanism is sealed, so that the detection mechanism is in a windproof and/or waterproof state, and foreign matters are prevented from entering the device to damage a circuit or influence a detection result.
