Abstract
The invention belongs to the field of air detection, and particularly relates to an air detection device and method. The air detection device comprises a shell, an air detection module and a heating module, wherein the air detection module and the heating module are located inside the shell. An air inlet and an air outlet are formed in the upper and lower corresponding positions of the shell. The air detection module is located on one side of the air inlet. The heating module is located on one side of the air outlet. Local air is heated above the air detection module through heat brought when a heating circuit portion works, and therefore natural air convection is accelerated. Air nearby the detection device is circulated more rapidly, and therefore the response time of controlling the detection device is shortened.
Description
Technical field
The invention belongs to air detection field, be specially a kind of air detecting device and method.
Background technology
Because room air horizontal flow speed is slow, although air has the upper and lower convection current of nature, flowing velocity is also very slow.For air detecting device, slower to the detection response speed of air.The two kinds of modes that mainly contain current air detection product solve the problem of air flowing: one adds fan, as Chinese patent CN103487557A " a kind of surrounding air pick-up unit ", comprise top and there is the kit (1) of open ports, pick-up unit shell (2), power supply (3), blower fan (4) and switch (5), wherein, the bottom of pick-up unit shell (2) wherein on a side is provided with opening (6), and kit (1) is placed on bottom in pick-up unit shell (2) through opening (6) packaged type, pick-up unit shell (2) top arranges air intake opening (7), blower fan (4) is arranged in pick-up unit shell (2), be positioned between air intake opening (7) and the position of placing kit (1), power supply (3) is connected with blower fan (4) through switch (5), but can bring noise, simultaneously bring extra cost and fan due to for a long time rotate be easy to damage, a kind of, be on product, open enough large hole, this can affect the aesthetics of finished product, as Chinese patent CN204116178U " a kind of air detection instrument " comprises the housing with opening, air-inlet cavity room is arranged with in housing, the bottom of air intake chamber offers the air inlet communicated with the external world, carrier base is provided with in housing, the openend of carrier base and housing is formed with the gap for air-out, carrier base installed the cartridge assemblies being connected with and detecting and analyze air quality and provide the battery of power supply for cartridge assemblies, cartridge assemblies comprises detection components, display and control assembly, voice broadcast assembly, main PCB plate and data transfer components, the air detection assembly that detection components comprises air-supply assembly and is disposed adjacent with air-supply assembly, more some equipment does not consider air circulation problem in the design, and so, the air passage rates in pick-up unit, to detected parameter delay of response.
And along with industrial expansion, environmental pollution is comparatively serious, be the technological means of necessity of outdoor environment in present sensing chamber to the detection of air quality, but the not very convenient effective air quality detecting device of existing equipment is for detecting air.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of air detecting device and method, this method realizes air natural convection current from bottom to top, shortens the response time of air detecting device.
For solving the problems of the technologies described above, the present invention is achieved through the following technical solutions, a kind of air detecting device, comprises housing, is positioned at the air detection module of housing and heating module, and described housing is provided with air intake opening and gas outlet in position corresponding up and down; Described air detection module is positioned at air intake opening side; Described heating module is positioned at the top of side, gas outlet air detection module.
As the technical scheme that the present invention improves, described air detection module inside is provided with heating circuit.
As the technical scheme that the present invention improves, the heat that described heating circuit produces is less than the heat that heating module produces.
As the technical scheme that the present invention further improves, also comprise heater element, described heater element is between air detection module and heating module or between heating module and air outlet.
Another object of the present invention is to provide a kind of air detection method, comprise the steps:
A air flows into through air intake opening, and air detection module detects leaked-in air;
The air that b detects through detection module, move upward inflow heating module, and heating module heats it, obtains the air after heating;
Air after c heating is flowed out by gas outlet, and forms cold and hot convection current with outside air, and wherein colder air sinks to flowing to air detecting device through air intake opening;
D repeats step a-c.
Wherein, can be used for detecting humiture, carbon dioxide, PM2.5 or VCO.
Principle of work of the present invention
The present invention designs with the principle that the device that thermal value is larger is spatially more top, by making the local air heating in air detecting device thus accelerating the air flowing in air detecting device;
Wherein, air detection module is positioned at the below of heating module, air is made first to flow through air detection module, flow through heating module part again, the air flowing through testing circuit part is that speed is accelerated, temperature humidity etc. are change not, ensures that the parameter that pick-up unit detects is consistent with surrounding air actual parameter;
Through heating module heating, air accelerates upwards to flow, thus in band motion detection device, air flowing velocity is from bottom to top accelerated, and promotes natural convection air, to realize the object of the response time shortening air detecting device.
The invention has the beneficial effects as follows:
For air detecting device, fan can not be used, the too large air vent affecting outward appearance and use need not be opened, only utilize heating during pick-up unit self-heating module work to accelerate the air passage rates in air detecting device, thus shorten the response speed of pick-up unit.
Cost-saving relative to fan solutions, greatly improve, also more save the energy due to rapid wear device, the stabilization of equipment performance not using fan such.And relative to the air detecting device of wide-bore, avoid because open the outward appearance that large air vent brings influenced, simultaneously, because large air vent scheme utilizes air natural to circulate, pick-up unit response speed is slow, and this scheme utilizing circuit to add hot-air acceleration natural convection air speed is then significantly improved to this.
Accompanying drawing explanation
