Description

Technical Field

[0001] The utility model relates to the technical field of gas alarms, and in particular to a gas alarm structure capable of preventing mosquitoes from blocking a fluid sensing channel. Background Art

[0002] In existing gas monitoring and alarm systems, gas alarms are key components widely used in industrial, commercial, and residential areas. They monitor hazardous gas concentrations in the air in real time and issue alerts when levels exceed standards, ensuring both personnel safety and environmental health. However, in practice, these alarms often face a common problem: small insects, such as mosquitoes, can easily enter the alarm through the air inlet, blocking the fluid sensing channel, leading to distorted monitoring data or equipment failure, thus compromising the accuracy and reliability of the alarm system.

[0003] Traditional solutions mostly rely on physical barriers such as fine metal mesh or plastic mesh to block mosquitoes, but these methods often have problems such as poor air permeability, easy clogging, and difficult maintenance. In addition, even if a mosquito net is set up, it is still difficult to completely prevent the invasion of tiny mosquitoes, especially in humid and warm environments. Mosquitoes are more active and pose a continuous threat to the normal operation of gas alarms. Therefore, in response to the above technical problems, a gas alarm structure is proposed here to prevent mosquitoes from clogging the fluid sensing channel. Utility Model Content

[0004] The purpose of the utility model is to provide a gas alarm structure that prevents mosquitoes from blocking the fluid sensing channel. Through the ingenious combination of the plug plate and the wedge block, the device body and the air intake cover can be easily installed and firmly locked. At the same time, the double protection of the double filter and the volatile mosquito repellent effectively blocks the invasion of mosquitoes, and the hemispherical smooth curved surface design of the air intake cover further enhances the anti-mosquito effect, making it difficult for mosquitoes to stay and facilitating subsequent cleaning and maintenance.

[0014] The technical solution of the utility model has at least the following beneficial effects:

[0015] The utility model proposes a gas alarm structure for preventing mosquitoes from clogging the fluid sensing channel. The structure uses the first filter and the second filter to perform double filtration, and the volatile mosquito repellent is put into the storage tube through the connecting pipe and diffused to the surroundings of the device body through the barrier net, thereby preventing mosquitoes from approaching. It can greatly prevent mosquitoes in the air from flying into the air intake hood. If there are still very small mosquitoes entering the air intake hood, since the air intake hood is a hemispherical shell with a smooth inner surface, the mosquitoes will have no place to land and will gather on the first filter or fall out directly. When it is necessary to clean the mosquitoes entering the air collection hood, it is only necessary to pull the connecting plate. At this time, the plug plate can be automatically popped out under the action of the second spring, and the separation of the device body and the air intake hood is completed quickly. The second filter can then be removed to clean the mosquitoes entering the air intake hood, which is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-9 The utility model proposes a gas alarm structure for preventing mosquitoes from blocking a fluid sensing channel, comprising a device body 1 and an air inlet cover 3. A gas analyzer 2 is fixedly connected to the interior of the device body 1, and a sound alarm 19 and a light alarm 20 are fixedly connected to the exterior of the device body 1.

[0028] A fixing ring 4 is fixedly connected to the lower side of the air intake hood 3, and a first filter screen 5 is provided at the bottom of the fixing ring 4. A mounting ring 6 is fixedly connected to the inner side of the air intake hood 3, and a second filter screen 7 is provided on the outside of the mounting ring 6. A plug-in plate 8 is fixedly connected to the upper side of the air intake hood 3, and a through hole 9 is provided on the outside of the plug-in plate 8. A slot 10 is provided at the bottom of the device body 1, and the slot 10 matches the plug-in plate 8. A wedge block 11 is slidably connected to the outside of the slot 10, a rebound mechanism is installed between the wedge block 11 and the device body 1, and a locking mechanism is installed on the inside of the slot 10.

[0029] The sound alarm 19 and the light alarm 20 are electrically connected to the gas analyzer 2 .

[0030] The rebound mechanism includes a connecting plate 12 and a first spring 13. The connecting plate 12 is fixedly connected to the outside of the wedge block 11. The first spring 13 is fixedly connected between the connecting plate 12 and the device body 1. The lower side of the wedge block 11 is beveled.

[0031] The locking mechanism includes a stopper 14 and a second spring 15 . The second spring 15 is fixedly connected to the inner side of the slot 10 . The stopper 14 is fixedly connected to the lower end of the second spring 15 , and the stopper 14 is close to the wedge block 11 .

[0032] The outside of the air intake cover 3 is fixedly connected to a storage pipe 16 , the outside of the storage pipe 16 is provided with a barrier net 17 , and the outside of the storage pipe 16 is fixedly connected to a connecting pipe 18 .

[0033] A mounting plate 21 is fixedly connected to the upper side of the device body 1 , and the device can be installed in various locations and occasions through the mounting plate 21 .

[0034] The working principle of a gas alarm structure for preventing mosquitoes from blocking the fluid sensing channel based on the embodiment is that when the device is installed, the plug plate 8 can be aligned with the slot 10 and directly inserted. Since the bottom of the wedge block 11 is an inclined surface, the wedge block 11 will be pushed outward under the action of force, and the first spring 13 will be stretched at the same time. When the wedge block 11 moves to the position of the through hole 9, it will automatically be stuck in the through hole 9 under the action of the first spring 13 to complete the positioning. At the same time, the top of the plug plate 8 will abut against the abutment plate 14, and the second spring 15 will be compressed, so that the plug plate 8 can be locked to prevent shaking, and the installation of the device body 1 and the air intake hood 3 can be completed. Then, when the device is installed in the place to be monitored through the mounting plate 21, the air passes through the first filter 5 and the second filter 7 and contacts the gas analyzer 2. After analysis by the gas analyzer 2, if there are too many harmful gases in the air, it will be detected through the sound. The sound alarm 19 and the light alarm 20 sound an alarm, and the mosquito repellent is double-filtered by the first filter 5 and the second filter 7, and the volatile mosquito repellent is put into the storage tube 16 through the connecting pipe 18, and diffused to the surrounding of the device body 1 through the barrier net 17, thereby preventing mosquitoes from approaching, and greatly preventing mosquitoes in the air from flying into the air intake cover 3. If there are still very small mosquitoes entering the air intake cover 3, since the air intake cover 3 is a hemispherical shell with a smooth inner surface, the mosquitoes will have no place to land, and will gather on the first filter 5 or fall out directly. When it is necessary to clean the mosquitoes entering the air collection cover, it is only necessary to pull the connecting plate 12. At this time, under the action of the second spring 15, the plug-in plate 8 can be automatically popped out, and the separation of the device body 1 and the air intake cover 3 is completed quickly. The second filter 7 can be removed and the mosquitoes entering the air intake cover 3 can be cleaned, which is more convenient.
