Description

Technical Field

[0001] This utility model relates to the field of gas detection equipment technology, and in particular to a combustible gas detector with a moisture-proof structure. Background Technology

[0002] In practical applications of combustible gas detectors, ambient moisture can easily damage internal electronic components and sensors, leading to decreased detection accuracy, equipment malfunction, and even safety hazards. Existing moisture-proof measures often employ a single sealing structure or a simple filter design, which is ineffective in handling complex and humid environments. For example, ordinary filters cannot completely block liquid water while allowing efficient airflow, and sealing structures are prone to failure due to aging and wear after prolonged use, allowing moisture to enter the detector and affecting its normal operation. Therefore, a new type of moisture-proof structure is urgently needed to improve the environmental adaptability and reliability of combustible gas detectors.

[0003] Therefore, the existing technology of gas detection equipment needs further improvement. Utility Model Content

[0004] The purpose of this invention is to provide a combustible gas detector with a moisture-proof structure. Through a unique structural design, it achieves efficient gas-water separation and moisture-proof functions, ensuring that the detector works stably and accurately in humid environments.

[0005] To achieve the above objectives, the present invention adopts the following solution:

[0006] A combustible gas detector with a moisture-proof structure includes a gas detector housing, on which a spiral channel is provided, and a spiral moisture-proof filter is provided in the middle of the spiral channel along the spiral path of the spiral channel. Multiple air inlet pipes are provided below the spiral channel, and the multiple air inlet pipes are connected to the lower inner surface of the spiral channel.

[0007] The gas detector housing of this utility model includes a housing body, on which a plurality of mounting bases are provided, and a gas detector is disposed inside the housing body.

[0008] The spiral moisture-proof filter of this invention divides the spiral channel into an upper gas channel and a lower moisture channel.

[0009] The surface of the lower moisture channel of this invention is coated with a hydrophobic material.

[0010] The number of turns of the plurality of spiral channels in this invention is less than 1.

[0011] The present invention provides a plurality of air intake pipes that are evenly distributed around the central circumference of the gas detector housing.

[0012] The lower end of the air intake pipe of this utility model is provided with a tapered chamfer.

[0013] The hydrophobic material described in this invention is a polytetrafluoroethylene coating, which is uniformly applied to the surface of the underlying moisture channels through a spraying process.

[0014] The spiral moisture-proof filter screen of this utility model is detachably connected to the inner wall of the spiral channel by means of a slot engagement. The inner wall of the spiral channel is provided with an annular slot, and the edge of the spiral moisture-proof filter screen is provided with a snap-fit ​​protrusion that matches the annular slot.

[0015] In summary, the advantages of this utility model over the prior art are:

[0016] This invention addresses the shortcomings of existing gas detection equipment. Through its structural design, it offers the following advantages: The combination of a spiral channel and a spiral moisture-proof filter achieves vapor-water separation. The spiral channel increases the travel distance of the moisture-laden gas, ensuring sufficient filtration time and effectively preventing water vapor from entering the detector. Compared to traditional moisture-proof structures, its moisture-proof performance is significantly improved. The circumferentially distributed design of the air inlet pipe ensures uniform and smooth gas entry, and its simple structure makes it easy to use. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4This utility model provides a combustible gas detector with a moisture-proof structure, including a gas detector housing 1. A spiral channel 2 is provided on the gas detector housing 1. A spiral moisture-proof filter 3 is provided in the middle of the spiral channel 2 along the spiral path of the spiral channel 2. Multiple air inlet pipes 4 are provided below the spiral channel 2, and the multiple air inlet pipes 4 are connected to the lower inner surface of the spiral channel 2. Combustible gas enters the spiral channel 2 through the air inlet pipes 4. As it rises along the spiral path, the spiral moisture-proof filter 3 uses physical barriers to separate the gas from the moisture. The gas continues to flow into the detector through the upper channel, while the moisture is discharged along the lower channel, realizing simultaneous moisture protection and gas collection.

[0023] The gas detector housing 1 of this utility model includes a housing body 101, on which a plurality of mounting seats 102 are provided, and a gas detector 103 is provided inside the housing body 101; the mounting seats 102 are used to fix the detector to a wall, pipe or other position, the housing body 101 provides physical protection for the internal detector 103, and at the same time supports the external spiral channel and other structures.

[0024] The spiral moisture-proof filter 3 of this invention divides the spiral channel 2 into an upper gas channel 301 and a lower moisture channel 302; it uses the pore size of the filter to filter gas molecules and water molecules: gas molecules with smaller diameters can pass through the filter and enter the upper channel; water molecules are blocked by surface tension or gravity and slide down the lower channel to be discharged, forming a gas-water separation channel.

[0025] The surface of the lower moisture channel 302 described in this invention is coated with a hydrophobic material; the hydrophobic material, such as polytetrafluoroethylene, reduces the adhesion between water and the channel surface, making it easier for water to slide down the channel wall and drain under the action of gravity, thus avoiding water accumulation that could affect the moisture-proof effect.

[0026] In this invention, the number of turns of the plurality of spiral channels 2 is less than 1.

[0027] In this invention, multiple air intake pipes 4 are evenly distributed around the central circumference of the gas detector housing 1.

[0028] The lower end of the air intake pipe 4 of this utility model is provided with a tapered chamfer of 100°.

[0029] The hydrophobic material described in this invention is a polytetrafluoroethylene coating, which is uniformly applied to the surface of the lower moisture channel 302 by a spraying process.

[0030] The spiral moisture-proof filter 3 of this utility model is detachably connected to the inner wall of the spiral channel 2 by means of a slot. The inner wall of the spiral channel 2 is provided with an annular slot, and the edge of the spiral moisture-proof filter 3 is provided with a snap-fit ​​protrusion that matches the annular slot.
