Abstract
The utility model relates to a noise reduction apparatus of an optical sensor. The noise reduction apparatus has a cylindrical housing, a cylindrical cavity is provided in the housing, the cavity is communicated with one end surface of the housing, the center of the other end surface of the housing is provided with a circular hole communicated with the cavity, cylindrical blocks are arranged in the cavity, the center of each block is provided with a rectangular through hole, at least two cylindrical blocks are provided, a gap is arranged between two blocks, and preferably, three blocks are provided. The noise reduction apparatus is advantageous in that the structure is simple, noise is effectively reduced, and test accuracy of the sensor is guaranteed.
Description
Technical field
The utility model relates to the sensor denoising device, relates in particular to a kind of optical sensor denoising device.
Background technology
In use,, there is certain noise in the defect due to design to optical sensor.Therefore its internal ventilation mouth is point-like, and sound is made an uproar greatlyr in venting process, and owing to existing certain sound to make an uproar, the air-flow that these sound are made an uproar easily to gas exerts an influence, thereby affects the accuracy of sensor test.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of and can reduce the optical sensor denoising device that the inner sound of optical sensor is made an uproar.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of optical sensor denoising device, has cylindrical housings, in described housing, be provided with circular cylindrical cavity, cavity and housing one end face connect, center, housing other end is provided with the circular hole of ganging up mutually with described cavity, in described cavity, is provided with cylindrical block, and the block center is provided with rectangular through-hole.
Further, described cylindrical block has two at least, and is provided with gap between block and block.
Again further, described block is preferably three.
Compared with prior art, usefulness of the present utility model is: this optical sensor denoising device is simple in structure, can make effectively to reduce sound and make an uproar, and guarantees the accuracy of sensor test.
The accompanying drawing explanation:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the utility model optical sensor denoising device structure cut-open view;
Fig. 2 is optical sensor denoising device inner cylinder block end face structure schematic diagram.
In figure: 1, housing; 11, cavity; 12, circular hole; 2, block; 21, rectangular through-hole.
Embodiment:
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail:
A kind of optical sensor denoising device shown in Figure 1, has cylindrical housings 1, in described housing 1, be provided with circular cylindrical cavity 11, cavity 11 connects with housing 1 one end faces, housing 1 center, other end is provided with the circular hole 12 of ganging up mutually with described cavity 11, in described cavity 11, is provided with at least two cylindrical blocks 2; In order to make noise reduction reach best, the block 2 in described cavity 11 is preferably 3; As shown in Figure 2, block 2 centers are provided with rectangular through-hole 21.
Particularly, gas enters in the cavity 11 of housing 1 from circular hole 12, owing in cavity 11, being provided with the block of center with rectangular through-hole 21, and between each block, all has certain gap, the flow velocity of the gas that therefore relaxes, gas becomes strip by point-like, has increased its area, reduce sound and made an uproar, guaranteed the accuracy of sensor test.
It is emphasized that: above is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, every foundation technical spirit of the present utility model, to any simple modification, equivalent variations and modification that above embodiment does, all still belongs in the scope of technical solutions of the utility model.
