DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to better understand the purpose, structure and function of the present utility model, the following will further describe in detail a water immersion alarm of the present utility model with reference to the accompanying drawings.

[0024] As Figures 1 to 4 shown, a water immersion alarm of the present utility model includes a housing 1. An alarm 3 is provided inside the housing 1, and a probe 5 is electrically connected below the housing 1 through a wire. When water touches the probe 5, the probe 5 conducts electricity to make the alarm 3 energized, and the alarm 3 will emit an alarm sound after being energized. To protect the inner cavity of the housing 1, a cover plate 2 is detachably attached to the opening of the housing 1 by screws, and a sound outlet hole 4 for the sound of the alarm 3 to pass out is provided on the cover plate 2. Among them, in the inner cavity of the housing 1, a fixing piece is provided at each of the four corners of the housing 1, and a screw hole is provided on the screw piece. And through holes are provided on the cover plate 2 corresponding to the positions of the respective screw holes. In this way, the cover plate 2 can be connected to the housing 1 by screwing the screws through the through holes on the cover plate 2 and then screwing the screws into the screw holes on the fixing pieces. To facilitate people to identify the alarm 3, an alarm lamp 14 is provided on the cover plate 2, and the alarm lamp 14 is electrically connected to the probe 5. At the same time, to fix the housing 1, a lifting member is provided on the housing 1. Specifically, the lifting member is preferably a lifting ear 16. Pass a screw through the through hole on the lifting ear 16 and then fix it on the installation main body. Among them, the lifting ears 16 are provided at both ends of the housing 1, and the setting of the two lifting ears 16 can increase the installation stability of the housing 1. Of course, the probe 5 can be fixed at an appropriate height on the external main body through an arc-shaped clamp for detecting the water level.

[0025] As Figure 3 and Figure 4As shown in the figure, a dust-proof component 6 is provided on the inner wall of the cover plate 2. Through the dust-proof component 6, when the alarm 3 is not working, external dust can be prevented from entering the housing 1, which affects the normal use of each electronic component in the housing 1. At the same time, the dust-proof component 6 can also clean the sound outlet holes 4 on the cover plate 2, preventing the accumulation of dust in the sound outlet holes 4 from causing the blockage of the sound outlet holes 4. Specifically, the dust-proof component 6 includes slide rails 61 symmetrically arranged with the center of the sealing plate 62 and a motor 64 provided on the inner wall of the sealing plate 62. The motor 64 is connected to an external power supply for power supply. Among them, the slide rails 61 are respectively arranged above and below the sound outlet holes 4 of the cover plate 2, and a sealing plate 62 for blocking the sound outlet holes 4 is slidably arranged between the two slide rails 61. At the same time, a scraping plate 65 adapted to the sound outlet holes 4 is provided at one end of the sealing plate 62. The scraping plate 65 can slide in the sound outlet holes 4, and the motor 64 is connected to the sealing plate 62 through a transmission part 63. It should be noted that the motor 64 is electrically connected to the alarm 3. When the alarm 3 is powered on and emits an alarm sound, the alarm 3 will send a signal to the motor 64, and the motor 64 will drive the sealing plate 62 to work through the transmission part 63, so that the sealing plate 62 releases the blocking of the sound outlet holes 4, so as to transmit the alarm sound of the alarm 3.

[0026] As Figure 4 shown, the transmission part 63 for connecting the motor 64 and the sealing plate 62 includes a rack 632 provided on the sealing plate 62. The rack 632 is arranged along the length direction of the sealing plate 62. A gear 631 is provided at the output end of the motor 64, and the gear 631 meshes with the rack 632. Specifically, after the motor 64 receives the signal from the alarm 3, it starts to work. The motor 64 drives the gear 631 at its output end, the gear 631 drives the rack 632, and the rack 632 drives the sealing plate 62 to slide in the slide rail 61, so that the sealing plate 62 releases the blocking of the sound outlet holes 4. At the same time, the scraping plate 65 provided at one end of the sealing plate 62 will also slide, and scrape and clean the dust in the sound outlet holes 4, preventing the problem of blockage of the sound outlet holes 4 caused by the accumulation of dust in the sound outlet holes 4. The operation is simple and convenient to use. Similarly, when the alarm 3 stops working, the alarm 3 will also send a signal to the motor 64, the motor 64 will reverse, and then drive the sealing plate 62 to move to the initial position through the transmission part 63.

[0027] Preferably, a guiding frame 7 is also provided on the cover plate 2 corresponding to the position of the motor 64, and the guiding frame 7 is symmetrically arranged with the center of the motor 64. The motor 64 is slidably arranged in the guiding frame 7 through a slider 8, and the slider 8 is arranged on the side wall of the motor 64. And an electric push rod 9 connected to an external power supply is also provided on the cover plate 2. The telescopic end of the electric push rod 9 is connected to the motor 64. When the electric push rod 9 works, it can drive the motor 64 to move. And the motor 64 moves in the guiding frame 7 through the slider 8, which can increase the stability of the motor 64 on the sealing plate 62, reduce the weight borne by the electric push rod 9 on the motor 64, and increase the service life of the electric push rod 9.

[0028] As shown Figure 3 In the figure, a resilient component is provided on the cover plate 2, and the resilient component is used in cooperation with the sealing plate 62. Specifically, the resilient component includes a first support plate 10 provided at one end of the sealing plate 62, and a second support plate 11 provided at one end of the inner wall of the cover plate 2. The first support plate 10 and the second support plate 11 are connected by a spring 12. When the motor 64 drives the sealing plate 62 to release the blockage of the sound outlet hole 4 through the transmission part 63, the sealing plate 62 will drive the first support plate 10 to move, and the first support plate 10 will compress the spring 12. When the alarm 3 stops working, the alarm 3 will send a signal to the electric push rod 9, and the electric push rod 9 will push the motor 64 to move, so that the gear 631 on the motor 64 disengages from the rack 632, and then the spring 12 will push the first support plate 10 and the sealing plate 62 towards the initial position. When the sealing plate 62 moves to the initial position, the scraper 65 will collide with the sound outlet hole 4, and the vibration generated by the collision will shake off the dust scraped on the scraper 65, achieving the cleaning work of the dust on the scraper 65.

[0029] As a further improvement, a limiting rod 13 is provided on the second support plate 11, and a limiting block is provided at the free end of the limiting rod 13. The limiting rod 13 passes through the spring 12 and penetrates the first support plate 10, and the first support plate 10 is located between the limiting block and the second support plate 11. The limiting block can limit the first support plate 10 to reduce the impact of the scraper 65 on the sound outlet hole 4. The setting of the limiting rod 13 can prevent the spring 12 from being overly bent, thus affecting the normal use of the spring 12. To prevent the alarm 3 from not being usable during a power outage, a battery 15 is also provided in the housing 1, and the battery 15 is electrically connected to the probe 5, the alarm, the alarm lamp 14, and the electric push rod 9.

[0030] Usage method: Fix the water immersion alarm 3 at an appropriate position, and then fix the probe 5 at an appropriate position using a clamp. When the probe 5 is touched by water, the probe 5 conducts electricity and makes the alarm 3 power on and emit an alarm sound. The alarm 3 will send a signal to the motor 64, and the motor 64 drives the sealing plate 62 to move through the transmission part 63, so that the sealing plate 62 releases the blockage of the sound outlet hole 4. During the movement of the sealing plate 62, the scraper 65 on the sealing plate 62 will scrape and clean the dust on the sound outlet hole 4. When the alarm 3 stops working, the alarm 3 will send a signal to the electric push rod 9, and the electric push rod 9 will push the motor 64 to move, so that the gear 631 on the motor 64 disengages from the rack 632 on the sealing plate 62. Then the spring 12 will push the sealing plate 62 to the initial position through the first pressing plate, causing the sealing plate 62 to collide with the sound outlet hole 4, and the vibration generated after the collision will shake off the dust on the scraper 65. Finally, the electric push rod 9 will drive the motor 64 towards the initial position, and during the movement, the gear 631 will engage with the rack 632 again.
