Technical Field

The utility model belongs to the technical field of the gas safety technique and specifically relates to a gas alarm device is related to.

Background

Natural gas brings great convenience to life, but forgetting to turn off a gas switch or aging of a gas pipe during use causes serious consequences. Usually, a gas alarm device is installed in a kitchen, and once gas leakage occurs, a reminder is given through the gas alarm device.

Most of the existing gas alarms have the condition of misinformation, which causes inconvenience to users. In order to ensure that the sensor in the gas alarm is in contact with the outside air, an air hole is usually formed in the housing of the gas alarm. And the gas pocket is too little to lead to the gas permeability poor, and the inductor response is insensitive, and the gas pocket is big then easily invaded by mosquito cockroach, does not clear up for a long time and can trigger the warning, leads to the wrong report. False alarm can be triggered under the condition of overhigh humidity; it is desirable to keep the chamber ventilated once gas leaks to reduce the gas concentration. Therefore, a gas alarm device which can prevent the invasion of mosquitoes and has high safety is needed.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1, 2, 3 and 4, a gas alarm device includes a lower housing 1, at least one set of air-permeable insect-proof devices is installed on the lower housing 1, preferably, two sets of air-permeable insect-proof devices are installed on the lower housing 1, and the two sets of air-permeable insect-proof devices are respectively installed on two side surfaces of the lower housing 1. The air-permeable insect-proof device comprises two air-permeable plates 3 which are parallel to each other, and the thickness of each air-permeable plate 3 is 15-32 mm. Each ventilation plate 3 is provided with a plurality of inclined holes 4, and the orifices of the inclined holes 4 are circular or elliptical, preferably circular holes. The inclined holes 4 penetrate through the breathable plate 3, the included angle between the hole axes of the inclined holes 4 and the plate surface of the breathable plate 3 is 25-45 degrees, and the hole diameters of the inclined holes 4 are 5-15 millimeters.

As shown in fig. 1, 2, 3, and 4, a gap 5 is provided between the two air permeable plates 3, and the bottom of the gap 5 penetrates the outside, i.e., the lower portion of the gap 5 is not covered and is communicated with the outside. The inclined holes 4 on the two sides of the gap 5 are opposite in inclination direction, the inclined holes 4 on the two sides of the gap 5 are arranged in a staggered mode, and the orifices on the two sides do not correspond to each other. When the mosquito or cockroach passes through the first ventilation plate 3 in the ventilative protection against insects device, because the slope design of inclined hole 4 causes inconvenience for the mosquito removes, when the mosquito goes out the inclined hole and gets into in the clearance 5, because the width of clearance 5 is 10-20 millimeters, directly hits second ventilation plate 3 under the inertial action to drop from clearance 5, thereby avoid mosquito and cockroach to get into the inside of casing 1 down. The inside of lower casing 1 is provided with inductor 10, and drying box 11 is still installed to the inside of lower casing 1, and drying box 11's inside is equipped with the drier, can prevent that the air humidity is too big around inductor 10 from leading to the wrong report.

As shown in fig. 1 and 5, an upper casing 2 is provided on the upper side of the lower casing 1, and an air pump 6 is mounted inside the upper casing 2. The air pump 6 is activated when the alarm sounds. An air inlet of the air pump 6 is connected with an air pipe 7, the air pipe 7 penetrates through the upper shell 2, and a conical cover 8 is installed at the tail end of the air pipe 7. A hose connector 13 is connected to an air outlet of the air pump 6, a corrugated hose 12 is connected to the other end of the hose connector 13, and the hose connector 13 is embedded in the upper case 2. The top of the upper shell 2 is provided with a pipe frame 9, and the pipe frame 9 is used for fixing a corrugated hose 12. The corrugated hose 12 is a stretchable hose, and when in use, the nozzle of the corrugated hose 12 extends out of the window, so that indoor ventilation can be promoted by the air pump 6 in case of gas leakage.

When using this gas alarm device, when mosquito or cockroach process first ventilative board 3 in the ventilative protection against insects device, because the slope design of inclined hole 4 causes inconvenience for the mosquito removes, when the mosquito goes out the inclined hole and gets into in clearance 5, because the width in clearance 5 is 10-20 millimeters, directly hits second ventilative board 3 under the inertial action to drop from clearance 5, thereby avoid mosquito and cockroach to get into the inside of casing 1 down. The inside of lower casing 1 is provided with inductor 10, and drying box 11 is still installed to the inside of lower casing 1, and drying box 11's inside is equipped with the drier, can prevent that the air humidity is too big around inductor 10 from leading to the wrong report. The orifice of the corrugated hose 12 extends out of the window, and once the gas leakage alarm rings, the air pump 6 is started, so that indoor ventilation can be promoted, and the indoor gas concentration can be reduced. The gas alarm device can prevent the invasion of mosquitoes and has high safety.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
