[0002] The burglar alarm is an alarm instrument that uses modern scientific and technological means to prevent crime and promptly detect criminal activities. There are many types of burglar alarms, which can be divided into switch alarms, sound alarms, induction alarms, infrared alarms, laser alarms, etc. based on their working principles. With the development of television technology and electronic computer technology, advanced monitoring and control alarm systems that use television and computers together have emerged. The alarm signals are transmitted in two ways: wireless and wired. With the strengthening of technical crime prevention work, burglar alarms have played a significant role.

[0003] At present, burglar alarms are divided into indoor and outdoor installations. For outdoor installed burglar alarms, they are easily eroded by rain, which can cause problems in the internal circuits and affect the normal use of the alarm. For this reason, we propose a burglar alarm with waterproof function. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a burglar alarm with waterproof function to solve the technical problems mentioned in the above background.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a burglar alarm with waterproof function, comprising a base, an alarm light is installed at the end of the base, and the alarm light is installed and connected to the base through a thread, a rainproof eave is provided on the outside of the end of the base located at the connection between the base and the alarm light, and the bottom end of the rainproof eave extends downward, a polyethylene plate is provided inside the base near the inner wall of the base, and a water diversion cavity is formed between the outer wall of the polyethylene plate and the inner wall of the base.

[0006] By adopting the above technical solution, external waterproofing is combined with internal waterproofing, thereby achieving a waterproof effect on the anti-theft alarm. In addition, rainwater can be used to dissipate heat from the anti-theft alarm and backwash the mesh plate.

[0007] The utility model is further configured that a heat dissipation hole is opened at the bottom end of the base, and a mesh plate is installed inside the heat dissipation hole.

[0008] By adopting the above technical solution, the effect of heat dissipation and dust prevention is achieved.

[0009] The utility model is further configured that the end surface of the base is located at the top of the rainproof eaves and a water collecting tank is installed, and the interior of the water collecting tank is connected to a water inlet pipe extending obliquely downward.

[0010] By adopting the above technical solution, the effect of water supply is achieved.

[0011] The utility model is further configured such that the end of the water inlet pipe extends to the inside of the base, and a U-shaped pipe connected to the water inlet pipe is arranged inside the base.

[0012] By adopting the above technical solution, the water supply effect of the U-shaped pipe is achieved.

[0013] The utility model is further configured that the end of the U-shaped tube is connected with a water outlet nozzle, and the water outlet nozzle is arranged just above the heat dissipation hole.

[0014] By adopting the above technical solution, the cooling water can be discharged and the screen can be recoil-cleaned.

[0015] In summary, the utility model mainly has the following beneficial effects:

[0016] 1. The utility model is provided with a rainproof eave, a polyethylene plate and a water diversion cavity. First, the alarm light is connected to the base, and then the base is installed on a fixed object to complete the installation of the anti-theft alarm. Then the anti-theft alarm can be used. In rainy days, rainwater will be evacuated under the action of the rainproof eaves, thereby preventing rainwater from affecting the connection between the alarm light and the base, achieving the effect of external waterproofing. Furthermore, if the base shell leaks and causes rainwater to enter the base, the rainwater will be intercepted by the polyethylene plate and, under the action of the water diversion cavity, the rainwater can be diverted to the heat dissipation hole for discharge, thereby achieving internal waterproofing. The combination of internal and external waterproofing greatly improves the waterproof performance of the anti-theft alarm.

[0017] 2. The utility model is provided with a water collecting tank, a water inlet pipe, a U-shaped tube and a water outlet nozzle. When it rains, rainwater will enter the water collecting tank and be stored, and the water in the water collecting tank will flow into the U-shaped tube through the water inlet pipe under the action of potential energy difference. When the rainwater flows in the U-shaped tube, it will take away the heat generated by the internal operation of the anti-theft alarm, thereby achieving the heat dissipation effect of the anti-theft alarm, and the water finally discharged from the U-shaped tube will be discharged through the water outlet nozzle. In this process, the sprayed water will have a backwash cleaning effect on the mesh plate, thereby simultaneously achieving the automatic cleaning effect of the mesh plate.

[0028] The working principle of the utility model is as follows: first, the alarm light 2 is connected to the base 1, and then the base 1 is mounted on a fixed object to complete the installation of the anti-theft alarm, and then the anti-theft alarm can be used;

[0029] On rainy days, rainwater will be evacuated under the action of the rainproof eaves 3, thereby preventing rainwater from affecting the connection between the alarm light 2 and the base 1, achieving the effect of external waterproofing. Furthermore, if the base 1 shell leaks and causes rainwater to enter the base 1, the rainwater will be intercepted by the polyethylene plate 5 and, under the action of the water diversion cavity 6, the rainwater can be drained to the heat dissipation hole 7 for discharge, achieving internal waterproofing, combining internal and external waterproofing, and greatly improving the waterproof performance of the anti-theft alarm;
