Detailed Description
The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings to fully understand the objects, the features and the effects of the present invention.
Fig. 1 is an exploded perspective view of the present invention. As shown in fig. 1, the waterproof and moistureproof household combustible gas detector comprises an upper cover 1, a lower shell 2 matched with the upper cover 1, and a gas sensor 3 arranged inside the upper cover 1, wherein the lower shell 2 and the upper cover 1 are of a cavity structure.
As shown in FIG. 1, the detector of the utility model is provided with a waterproof sealing ring 4 on the sealing surface of an upper cover 1 and a lower cover 2, when the upper cover 1 is screwed on the lower cover 2 by a fastener, the surface of the lower cover 2 opposite to the upper cover 1 presses on the waterproof sealing ring 4, the more the fastener is screwed, the greater the pressure of the upper cover 1 and the lower cover 2 on the waterproof sealing ring 4 is, and the better the sealing performance between the upper cover 1 and the lower cover 2 is. Specifically, a circle of sealing ring groove 9 is formed in the surface, in contact with the lower shell 2, of the cavity wall of the upper cover 1, the sealing ring groove 9 is bent inwards at the positions of the four corners of the upper cover 1 to avoid fastener holes connecting the upper cover 1 and the lower shell 2, and therefore thin ribs are newly added in the four corners of the upper cover 1 to form the sealing ring groove 9. The waterproof sealing ring 4 is embedded in the sealing ring groove 9, and correspondingly, the waterproof sealing ring 4 is rectangular and is inwards bent at four corners. The sealing structure can prevent moist air or liquid from entering the detector from the holes of the fastening piece on the upper cover 1, and the bent shape of the waterproof sealing ring 4 is more convenient for sealing, so the sealing effect of the detector is better.
As shown in fig. 1 and 2, a cylindrical buzzer mounting seat 11 is vertically arranged in an upper cover 1 of the utility model, a buzzer hole 7 is arranged at a position of a bottom plate of the upper cover 1 corresponding to the buzzer mounting seat 11, and a waterproof breathable film 5 is arranged at the position of the buzzer hole 7 and on the inner side of the upper cover 1. The outer part of the buzzer 6 is sleeved with a buzzer sealing sleeve 10 and then is arranged in a buzzer mounting seat 11 hole, and the end part of the buzzer 6 presses the waterproof breathable film 5 into the inner surface of the upper cover 1. The waterproof breathable film 5 is circular, the diameter of the waterproof breathable film is smaller than the inner aperture of the buzzer mounting seat 11, waterproof glue is coated on one side or two sides of the waterproof breathable film, and the waterproof breathable film 5 is adhered to the inner surface of the upper cover 1 through the waterproof glue.
The utility model selects a white waterproof breathable film 5 with the thickness of 0.15mm, and the air permeability is 2000-2500 ml/cm2Min, water pressure resistance of 20kpa, temperature resistance range: the temperature is-40 ℃ to +125 ℃, and the protection level of IP68 can be achieved.
The waterproof breathable film 5 is adhered to the buzzer hole 7 of the detector, the sound of the buzzer 6 can be smoothly transmitted by utilizing the breathable characteristic of the waterproof breathable film 5, and dust, dirt or liquid is prevented from entering the detector upper cover 1 by utilizing the waterproof characteristic of the waterproof breathable film 5, so that the waterproof purpose can be achieved by arranging the waterproof breathable film 5, and the normal transmission of the alarm sound is not influenced.
As shown in fig. 2, a sealing sleeve 8 is further arranged outside the gas sensor 3, the sealing sleeve 8 comprises a flange 81 and a cylinder 82, an inner hole of the sealing sleeve 8 is sleeved outside the gas sensor 3, the outside of the cylinder 82 is in contact with the upper cover 1, an end face of the flange 81 connected with the cylinder 82 is pressed on a step inside the upper cover 1, and the flange 81 of the sealing sleeve 8 not only increases the sealing effect, but also plays a role in axially fixing the sealing sleeve 8. The sealing sleeve 8 is arranged between the gas sensor 3 and the upper cover 1, and dust and liquid are blocked outside the upper cover 1, so that the sealing effect of the detector is enhanced.
In addition, in order to ensure that the data displayed in the upper cover 1 can be clearly seen, the middle of the upper cover 1 of the utility model is made of plastic material with good light transmittance.
