Detailed Description
This high-sensitivity fire smoke alarm, as shown in figure 1, including body 1, the stable set and the support to each partial structure of body 1 that sets up are realized, ensure the stable realization of whole smoke alarm function of structure, body 1 can play the guard action to the part of inside, prevent external mosquito, foreign matter etc. get into inside body 1, body 1 top bottom surface fixedly connected with sensor, the sensor can turn into the signal of telecommunication with smog, thereby make high-sensitivity fire smoke alarm send out the police dispatch newspaper, body 1's bottom fixedly connected with safety cover 2, a plurality of logical grooves have been seted up to the perisporium of safety cover 2, logical inslot fixedly connected with filter screen 3, safety cover 2 can block the foreign matter outside safety cover 2, filter screen 3 on the safety cover 2 can make tiny smog pass through, this filter screen 3 can also filter great granule outside filter screen 3 simultaneously, thereby make smog enter into inside high-sensitivity fire smoke alarm, and then smog conveys the sensor and converts the signal of telecommunication, finally realize high-sensitivity fire smoke alarm function of smoke alarm.
As shown in fig. 2 and 3, two annular air guide members 4 are fixedly connected to the inner wall of the cylindrical protection cover 2, the top of the body 1 is fixedly connected with a pump air guide member 5 communicated with the two air guide members 4, the pump air guide member 5 is an air pump, so that air can flow to the air guide member 4 from the pump air guide member 5, and meanwhile, the opening of the vent groove 6 faces the filter screen 3, and the air can flow from the vent groove 6 to the filter screen 3 because of air pressure.
As shown in fig. 1, fig. 3 and fig. 5, the equal fixedly connected with annular rubber ring 9 of air guide 4 that is located the air duct 6 both sides, top surface and interior bottom surface fixedly connected with are used for sealing air duct 6 and accomodate the morpheme 7 in air duct 6 in rubber ring 9, the material of morpheme 7 is soft silica gel piece, consequently, when morpheme 7 takes place to deform, rubber ring 9 can play the effect of stepping down for morpheme 7, be formed with ventilative seam 13 between the outer wall of rubber ring 9 and the inner wall of safety cover 2, prevent that rubber ring 9 from offsetting the production clearance dead angle with the inner wall of safety cover 2, rubber ring 9 is close to the lateral wall of filter screen 3 and sets up jagged 12, make the gap between rubber ring 9 and the filter screen 3 grow, when smog gets into inside body 1 through filter screen 3 from the body 1 outside, make things convenient for smog to cross rubber ring 9 from the breach of setting up and flow to sensor department from the jagged 12, the stability of the whole smog sensing alarm function of reinforcing structure.
As shown in fig. 3 and 5, deformation sheet 7 is good in elasticity and easy to deform, when gas passes through vent groove 6, gas pressure enables deformation sheet 7 to deform, deformation sheet 7 is bent to vent groove 6 at the center along the thickness direction, when gas flows into vent groove 6, first spherical magnet 10 is fixedly connected to the bent part of deformation sheet 7, second spherical magnet 11 attracted with first spherical magnet 10 is fixedly connected to the inner wall of vent groove 6, when gas does not flow into vent groove 6, because of second spherical magnet 11 fixed connection is on the inner wall of vent groove 6, first spherical magnet 10 can move to second spherical magnet 11 and drive deformation sheet 7 to fold and store in vent groove 6 because of magnetic force.
As shown in fig. 1, fig. 3 and fig. 5, after the air is filled in the vent groove 6, the air in the vent groove 6 contacts with the deformation sheet 7 to generate pressure on the deformation sheet 7, thereby the deformation sheet 7 deforms towards the direction of the filter screen 3, thereby the deformation sheet 7 penetrates out of the vent groove 6 to offset the filter screen 3, meanwhile, a plurality of air outlets 8 are formed in the deformation sheet 7 along the thickness direction, the air outlets 8 have a gathering effect on the air, thereby the air outlets 8 enable the air to be concentrated, and further the air pressure when the air passes through the air outlets 8 is larger, therefore, the air in the vent groove 6 presses the deformation sheet 7 to offset the filter screen 3, the air pressure in the vent groove 6 is higher than the air pressure outside the vent groove 6 and the air pressure outside the high-sensitivity fire smoke alarm, therefore, the air can flow from the vent groove 6 to the outside the filter screen 3 through the filter screen 3 offsetting the deformation sheet 7 through the air outlets 8, and further can take away part of dust on the filter screen 3, thereby the effect of cleaning the dust on the filter screen 3 is achieved. One side of the deformation sheet 7 close to the filter screen 3 is coated with a dustproof nano coating, so that when the deformation sheet 7 blocks dust from entering the interior of the high-sensitivity fire smoke alarm, the dust is prevented from being adsorbed on the deformation sheet 7.
The working principle is as follows: when pump gas spare 5 starts, pump gas spare 5 is to 4 pump gas of air guide spare, gas can get into in air channel 6 through the gas-supply pipe, when the gas in air channel 6 is full of, gas can oppress the deformation piece 7 and take place the deformation to filter screen 3 direction, thereby make deformation piece 7 and filter screen 3 offset, the gas outlet offsets with filter screen 3 this moment, gas flows to the outside of body 1 through filter screen 3 from the gas outlet on deformation piece 7, the gas that flows in this process can take away partial dust on the filter screen 3 and reach the deashing process of filter screen 3, at this moment because deformation piece 7 offsets with filter screen 3, therefore can realize the effect of sheltering from to the raise dust at the in-process deformation piece 7 of deashing, reduce the dust that raises and enter into the inside volume of structure, when pump gas spare 5 closes, because of the atmospheric pressure decline in the air channel 6 that disappears, first spherical magnet 10 can be attracted to second spherical magnet 11 department because of magnetic force, first spherical magnet 10 can drive deformation piece 7 and turn over the air channel 6 in the turn over.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
