Description
Technical field
The utility model relates to sensor technical field, refers to a kind of gas sensor especially.
Background technology
Gas sensor configuration in the past, owing to entering, the spacing of gas outlet is short, and enter, gas outlet is in the same rectilinear direction of radial direction, gas is little to gas outlet pressure constant interval from air intake opening, in this interval, pressure gradient is large, and the inherent distance of cylindrical shell is entered, the relative homeostasis of areal pressure that gas outlet is far away, gas is seldom had to flow, this region is made to be in " building the pressure " state, detect most quilt " short circuit " of runner, gas detector fully cannot contact with tested gas, thus make accuracy of detection low, existing gas sensor simultaneously, be mostly the function only with mensurated gas composition concentration.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of gas sensor, tested gas can be made fully to contact with detector, thus improve the precision of detection, and can concentration, the temperature and humidity of Simultaneously test gas, practical.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of gas sensor, comprise cylindrical shell, the air intake opening that cylindrical shell upper end is provided with and cylindrical shell side are provided with gas outlet, by fixed head, detection runner is installed in described cylindrical shell, described detection runner upper end is hollow, cylindrical tube, lower end is curved pipe, described detection runner is communicated with cylindrical shell by screen pack, the inwall left and right sides of described detection runner is provided with some gas detectors, described gas detector comprises gas concentration detector, gas humidity detector, gas temperature detector, before and after the inwall of described detection runner, some flaps are installed, described flap and gas detector symmetry are installed, described gas outlet is connected with curved pipe, disk is provided with between described air intake opening and detection runner, described disk is provided with some irregular projections, described disk one end is connected with motor by rotating shaft, described motor is arranged on described cylindrical shell, described motor and cylindrical shell are seamless link.
As preferably, described motor is double steering motor.
As preferably, described gas outlet is provided with connecting pipe, can be used for collecting gas.
The utility model has following beneficial effect:
Tested gas can be made fully to contact with detector, thus improve the precision of detection, and can concentration, the temperature and humidity of Simultaneously test gas, practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
With reference to Fig. 1, this embodiment is by the following technical solutions: a kind of gas sensor, comprise cylindrical shell 1, the air intake opening 2 that cylindrical shell 1 upper end is provided with and cylindrical shell 1 side are provided with gas outlet 6, it is characterized in that, be provided with by fixed head 8 in described cylindrical shell 1 and detect runner 3, described detection runner 3 upper end is hollow, cylindrical tube, lower end is curved pipe, described detection runner 3 is communicated with cylindrical shell 1 by screen pack 13, the inwall left and right sides of described detection runner 3 is provided with some gas detectors, described gas detector comprises gas concentration detector 9, gas humidity detector 10, gas temperature detector 11, before and after the inwall of described detection runner 3, some flaps 12 are installed, described flap 12 is installed with gas detector symmetry, described gas outlet 6 is connected with curved pipe, disk 7 is provided with between described air intake opening 2 and detection runner 3, described disk 7 is provided with some irregular projections, described disk 7 one end is connected with motor 4 by rotating shaft 5, described motor 4 is arranged on described cylindrical shell 1, described motor 4 and cylindrical shell 1 are seamless link.
Described motor 4 is double steering motor.
Described gas outlet 6 is provided with connecting pipe, can be used for collecting gas.
Wherein, also comprise a display screen, described display screen is arranged on the outer wall of cylindrical shell 1, and described display screen is connected with described gas concentration detector 9, gas humidity detector 10, gas temperature detector 11, motor 4 by power lead, and described display screen is touch-screen.
This specifically implements the dust that can be fallen by filter screen filtration in tested gas, thus extend the serviceable life of detector, disk 7 is driven to rotate by motor 4, thus drive the air-flow of disc circumference, counter motion, because disk 7 is provided with irregular projection, thus increase the surface of contact of disk 7 and gas, well reduce the flow velocity of gas, the setting of flap, makes tested gas fully contact with detector further, thus improves the precision of detection simultaneously, and can concentration, the temperature and humidity of Simultaneously test gas, practical.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
