Description
Technical field
This utility model relates to a kind of sampling apparatus, particularly relates to a kind of environmental protection atmosphere sampler.
Background technology
Atmosphere sampler is to gather atmosphere pollution or the instrument of air being contaminated or device, and atmosphere sampler plays a good role for the detection of harmful gas in air and environment.The pollutant such as the formaldehyde in architectural engineering room air, ammonia, benzene being carried out sampling and typically requires constant flow sampler, constant flow sampler needs to use microsystem to be controlled turnover air quantity, and price is higher and structure is complicated, not readily portable.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, it is provided that a kind of enter the stable environmental protection atmosphere sampler of air inflow.
The purpose of this utility model is achieved through the following technical solutions.
A kind of environmental protection atmosphere sampler, including housing, handle and air outlet it is provided with on described housing, by installing hole, air guide cap is installed on described housing, described installing hole is screwed hole, described air guide cap includes gas cap head and gas cap handle, described gas cap head-shield is located at the front of gas cap handle, described gas cap handle with installing hole for threadeding, air flue through before and after being provided with in described gas cap handle, it is provided with gas outlet between rear portion surrounding and the gas cap handle of described gas cap head, described gas outlet connects with the air flue being arranged in gas cap handle, it is provided with gap between rear end and the housing of described gas cap head, the rear end of described gas cap handle has been threaded connection adjusting nut, described adjusting nut is positioned at hull outside, described air flue is connected with collapsible tube by connecting tube.
The further technical scheme of this utility model is: described gas cap head is connected to the front end of gas cap handle by some grid.
This utility model takes above-mentioned technological means to produce and provide the benefit that: environmental protection atmosphere sampler of the present utility model, the size in gap can be adjusted by adjusting nut, thus it is conveniently adjusted and stablizes the size in gap, make the throughput of entrance housing reach the state set.
Accompanying drawing explanation
Fig. 1 is the structural representation of environmental protection atmosphere sampler of the present utility model.
In figure, 1-housing, 2-handle, 3-installing hole, 4-air outlet, 5-connecting tube, 6-collapsible tube, 7-air guide cap, 8-gas cap head, 9-gas cap handle, 10-air flue, 11-gap, 12-gas outlet, 13-adjusting nut, 14-grid.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings and this utility model is described in further detail by embodiment.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
nullEnvironmental protection atmosphere sampler of the present utility model is as shown in Figure 1，Including housing 1，Handle 2 and air outlet 4 it is provided with on housing 1，By installing hole 3, air guide cap 7 is installed on housing 1，Installing hole 3 is screwed hole，Air guide cap 7 includes gas cap head 8 and gas cap handle 9，Gas cap head 8 is located at the front of gas cap handle 9，Gas cap handle 9 with installing hole 3 for threadeding，Air flue 10 through before and after being provided with in gas cap handle 9，It is provided with gas outlet 12 between rear portion surrounding and the gas cap handle 9 of gas cap head 8，Gas outlet 12 connects with the air flue 10 being arranged in gas cap handle 9，It is provided with gap 11 between rear end and the housing 1 of gas cap head 8，The rear end of gas cap handle 9 has been threaded connection adjusting nut 13，Adjusting nut 13 is positioned at the outside of housing 1，Air flue 10 is connected with collapsible tube 6 by connecting tube 5，Gas cap head 8 is connected to the front end of gas cap handle 9 by some grid 14.
Environmental protection atmosphere sampler of the present utility model, can be adjusted the size in gap 11, thus be conveniently adjusted and stablize the size in gap 11 by adjusting nut 13, makes the throughput of entrance housing 1 reach the state set.
Embodiment described above only have expressed embodiment of the present utility model, and it describes more concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
