Description

Technical Field

[0001] This utility model relates to the field of air horn technology, specifically to an air horn. Background Technology

[0002] An air horn is a device that uses compressed air to drive a sound-generating device to produce a high-decibel sound. It is widely used in transportation, industrial safety, and special occasions. Its core structure typically includes an air compressor, an air cylinder, a solenoid valve, and the horn body. When working, compressed air impacts a metal diaphragm or reed to generate a powerful sound wave with a volume of 100-150 decibels, far exceeding that of ordinary electric horns. In vehicles such as cars, trains, and ships, air horns are mainly used for long-distance warnings or signal transmission in harsh environments; in industrial settings, they are often used for factory safety alarms; and in some special fields such as sports events and emergency rescue, they are also used as a signaling tool.

[0003] Publication number CN108831428B discloses a multi-tone electrically controlled air horn, including a connecting cylinder. An end cap is fixedly mounted on the rear end surface of the connecting cylinder by screws. Mounting side plates are fixedly welded to both sides of the front end surface of the connecting cylinder. Air outlets are provided at both ends of the outer surface of the connecting cylinder. Positive end magnets are fixedly connected to both ends of the inner surface of the connecting cylinder. A control rod is slidably connected to the inner surface of the connecting cylinder. A ventilation cavity is provided inside the control rod. Connecting ventilation holes are provided at both ends of the inner surface of the ventilation cavity. The outer surface of the connecting ventilation holes... The inner surface of the control rod is connected to the air outlet. The control rod has wire holes on both sides of the inner front end. A coil is slidably connected to the inner surface of the wire hole. The outer surface of the coil is wound around the center of the outer surface of the control rod. This multi-tone electronically controlled air horn can greatly improve the convenience and stability of use. However, this technology does not have a dustproof structure at the air inlet. Under long-term use, dust, sand and other particles in the air will directly enter the air horn with the airflow. Long-term accumulation will block the air passage or jam the vibrating parts, resulting in a decrease in sound, distortion or even complete failure. Therefore, this technology still has some room for improvement. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an air horn in response to the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air horn, including a connecting seat, with air horns at both ends of the connecting seat, a drive motor at the top of the connecting seat capable of controlling the air horns to produce sound, and air outlets communicating with the air horns on both sides of the connecting seat. The characteristic feature is that: a mounting hole is opened on one side of the connecting seat, and a mounting box for installing a filter screen can be detachably installed in the mounting hole, with the mounting box placed on the surface of the connecting seat.

[0016] By adopting the above technical solution, the solenoid valve can be stably assembled through the fixing block and the vertical connecting piece. The matching design of the plug slot and the connecting piece simplifies the installation and positioning process of the solenoid valve and improves the assembly efficiency. The electrical connection design between the drive motor and the solenoid valve can realize the automatic control of the air circuit opening and closing. Combined with the sounding logic of the air horn, a linkage mechanism is formed to enhance the intelligence of the equipment. The modular plug structure facilitates the individual replacement and maintenance of the solenoid valve.

[0017] The aforementioned air horn can be further configured such that: one side of the connecting seat is provided with a T-shaped seat for fixed installation with the outside, and both ends of the T-shaped seat are provided with connecting grooves for connection with the outside.

[0018] By adopting the above technical solution, the T-shaped base provides a stable external mounting foundation for the connector, and the connecting slots at both ends can be adapted to various external fixing methods, enhancing the versatility of installation scenarios.
