Abstract
The utility model discloses a monitoring channel structure for dust detection device, the venthole of being seted up by the base bottom surface constitutes with base upper portion intercommunication institute, a breach has been seted up to this base bottom surface, be provided with on the breach with this breach complex movable cover, the venthole is located this movable cover. The utility model discloses a new structural design, increased the movable cover of being convenient for to clean, take off behind the movable cover non professional alright clean easily, do not influence its precision and sensitivity simultaneously.
Description
Technical field
This utility model relates to dust investigating, especially a kind of sense channel structure for dust investigating。
Background technology
Now, PM2.5 (diameter finely ground particles less than 2.5um) is closely bound up with health, directly results in being substantially increased of various respiratory tract disease sickness rate。Continuous deterioration in view of air quality, air purifying process and air cleaning series products obtain swift and violent development, the numerical value of PM2.5 is also increasingly paid close attention to by people simultaneously, this is accomplished by the dust concentration situation that a high-precision dust investigating embodies in air intuitively, to determine the need for room air is purified, or it is movable if appropriate for carrying out some to assess oneself residing environment。
Therefore, have Crinis Carbonisatus to understand dust investigating that a patent No. is 201410476778.X, its volume is little, cost is low, it is easy to carry, and the feature such as low in energy consumption, but after the induction apparatus life-time service of this dust investigating light-receiving module, optical glass can adhere to oil stain and dust, affect accuracy of detection and induction sensitivity, could removing stain or wiping after needing entirety to disassemble, current its optical glass position of existing such structure layman can not carry out removing stain or wiping operation, is unfavorable for the maintenance of device and accurate operation。
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of removable sense channel structure for dust investigating。
The technical solution adopted in the utility model is:
A kind of sense channel structure for dust investigating, the venthole offered by base bottom surface connects with pedestal top and is constituted, this base bottom surface offers a breach, and breach is provided with the removable cover coordinated with this breach, and described venthole is positioned on this removable cover。
One of preferably, described removable cover is fastened on the breach of base bottom surface。
Preferred two, described removable cover coordinates with the notch implant of base bottom surface。
Preferred three, described removable cover is threadeded with the breach of base bottom surface。
Preferred four, described removable cover is hinged with the gap edge of base bottom surface to be overturn at breach for removable cover。
The beneficial effects of the utility model:
This utility model have employed new structural design, adds the removable cover being easy to wiping, and after taking off removable cover, layman just can carry out wiping easily, does not affect its precision and sensitivity simultaneously。
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further。
Fig. 1 is the installation diagram of this utility model sense channel structure；
Fig. 2 is the exploded view of this utility model sense channel structure。
Detailed description of the invention
As Figure 1-Figure 2, for a kind of sense channel structure for dust investigating of the present utility model, the venthole 20 offered by pedestal 10 bottom surface connects with pedestal top and is constituted, this pedestal 10 bottom surface offers a breach 101, being provided with the removable cover 30 fastened with this breach 101 on breach 101, venthole 20 is positioned on this removable cover 30。
It is fastened and connected except above-mentioned between removable cover 30 and breach 101, also can adopt: removable cover 30 coordinates with breach 101 latch of base bottom surface；Or, removable cover 30 is threadeded with the breach 101 of base bottom surface；Or, removable cover 30 is hinged with breach 101 edge of base bottom surface to be overturn at breach 101 for removable cover 30。
It can be seen that the technical program have employed new structural design, adding the removable cover 30 being easy to wiping, after taking off removable cover 30, layman just can carry out wiping easily, does not affect its precision and sensitivity simultaneously。
The foregoing is only preferred embodiments of the present utility model, this utility model is not limited to above-mentioned embodiment, broadly falls within protection domain of the present utility model as long as realizing the technical scheme of this utility model purpose with essentially identical means。
