[0002] Elevators, as an indispensable vertical transportation tool in modern buildings, are widely used in residential buildings, commercial buildings, hospitals, office buildings, and other places. To ensure that passengers can communicate with the outside world in a timely manner during elevator operation, elevator intercoms have become an important component of the elevator system. Elevator intercoms are typically used in emergencies, allowing passengers to use them to request help or obtain assistance from people outside the elevator.

[0003] Existing elevator intercoms typically employ a waterproof sealing design to isolate moisture from the air. However, after prolonged use, the sealing ring may lose its sealing effect due to oxidation. The lack of an active dehumidification device allows moisture to seep into the equipment, leading to short circuits or corrosion. Utility Model Content

[0004] To overcome the problem that existing elevator intercoms generally use a waterproof sealing design to isolate moisture in the air, the sealing ring may lose its sealing effect due to oxidation after long-term use, which can cause moisture to seep into the equipment and lead to short circuits or corrosion, a high humidity anti-corrosion elevator intercom is proposed.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figures 1-5 This utility model provides an embodiment of a high-humidity, corrosion-resistant elevator intercom, including a protective box 1; it also includes a fan 101 and a storage component; the fan 101 is fixedly connected to the top of the inner wall of the protective box 1, and multiple heat dissipation holes 102 are opened through the bottom of the inner wall of the protective box 1; a second groove 103 is opened at the lower end of the protective box 1, and a screw 104 is rotatably installed on the inner wall of the second groove 103; a motor 105 is fixedly connected to the front end of the protective box 1, and the output shaft of the motor 105 passes through the protective box 1 and is fixedly connected to the front end of the screw 104; a sealing plate 106 for sealing is threaded on the outer wall of the screw 104; a control panel 2 is fixedly connected to the front end of the protective box 1, and a storage component is provided at the front end of the control panel 2 for easy access; by starting the motor 105, the screw 104 is rotated, thereby driving... The dynamic sealing plate 106 moves back and forth on the inner wall of the second tank 103 to block the heat dissipation hole 102, keeping the internal space of the protective box 1 sealed. After a period of time, the electronic components inside the protective box 1 raise the internal temperature of the protective box 1 by the heat they emit. Under the blowing of the fan 101, the hot air circulates inside the protective box 1 to dry the internal moisture and prevent excessive moisture from damaging the circuit board 4. Then, the screw 104 reverses and drives the sealing plate 106 to release the seal. Under the action of the fan 101, the accumulated hot air inside is discharged, which solves the problem that the sealing ring may lose its sealing effect due to oxidation. Due to the lack of an active dehumidification device, moisture may seep into the equipment, causing short circuits or corrosion.

[0021] Please see Figure 2 and Figure 3In this embodiment, a rear cover plate 3 is fixedly connected to the inner wall edge of the protective box 1, a circuit board 4 is fixedly connected to the front end of the rear cover plate 3, a heat-conducting plate 5 is fixedly connected to the front end of the rear cover plate 3, cable management holes 6 are opened through the upper and lower ends of the heat-conducting plate 5, and mounting plates 7 are fixedly connected to the four corners of the rear cover plate 3. A bolt 8 is provided at the other end of the mounting plate 7, and the other end of the bolt 8 is threaded to the rear end of the protective box 1. Through the heat-conducting plate 5, the heat emitted by the circuit board 4 can be released to the outside, avoiding the accumulation of hot air and damage to the circuit board 4. By rotating the bolt 8, the circuit board 4 can be easily disassembled, so that it can be maintained.

[0022] Please see Figure 5 In this embodiment, the storage component includes a third trough 201, a storage box 202, silica gel desiccant 203, an observation window 204, and a handle 205. The control panel 2 has a through-hole third trough 201 at its front end. The storage box 202 is slidably disposed on the inner wall of the third trough 201. The lower end face of the storage box 202 is in contact with the inner wall of the protective box 1. Multiple silica gel desiccants 203 are disposed on the inner wall of the storage box 202. An observation window 204 is provided at the front end of the storage box 202. Two handles 205 are fixed to the front edge of the storage box 202. By placing silica gel desiccant 203 inside the storage box 202, the moisture inside the protective box 1 can be absorbed. The changes in the color and shape of the silica gel desiccant 203 can be seen directly through the observation window 204, so that the silica gel desiccant 203 can be replaced in time to avoid the silica gel desiccant 203 from becoming ineffective.

[0023] Please see Figure 1 and Figure 4 In this embodiment, a first groove 9 is provided at the right end of the protective box 1. A battery 10 is installed inside the first groove 9. A limit groove 11 is provided at the top of the inner wall of the first groove 9. A protective plate 12 is installed on the inner wall of the first groove 9. A limit plate 13 is fixedly connected to the upper end of the protective plate 12. A screw 14 is threadedly installed at the right end of the protective plate 12. A controller 15 and an alarm button 16 are fixedly connected to the front end of the control panel 2. A speaker 17 is provided at the front end of the control panel 2. A light 18 is fixedly connected to the edge of the front end of the control panel 2. Pressing the alarm button 16 triggers the alarm device and simultaneously connects the property duty phone to send a distress signal. Turning on the light 18 illuminates the interior of the elevator to avoid panic among passengers. The battery 10 provided at the right end of the protective box 1 can provide backup power for the equipment.

[0024] During use, the controller 15 controls the motor 105 to start and rotate the screw 104, thereby driving the sealing plate 106 to move back and forth on the inner wall of the second groove 103, blocking the heat dissipation hole 102 and keeping the internal space of the protective box 1 sealed. After a period of time, the electronic components inside the protective box 1 raise the internal temperature of the protective box 1 by the heat they emit. Under the blowing of the fan 101, the hot air circulates inside the protective box 1, drying the internal moisture and preventing excessive moisture from damaging the circuit board 4. Afterwards, the screw 104 reverses and drives the sealing plate 106 to release the seal, and the hot air accumulated inside is discharged under the action of the fan 101.

[0025] By placing silica gel desiccant 203 inside the storage box 202, the moisture inside the protective box 1 can be absorbed. When the staff inspects the box, they can directly see the changes in the color and shape of the silica gel desiccant 203 through the observation window 204, so as to replace the silica gel desiccant 203 in time and avoid the silica gel desiccant 203 from becoming ineffective.

[0026] When an elevator malfunctions, pressing the alarm button 16 triggers the alarm device and simultaneously connects the property management office to send a distress signal. Turning on the lighting 18 illuminates the interior of the elevator to prevent passengers from panicking. A battery 10 located on the right side of the protective box 1 provides backup power for the equipment.

[0027] Through the above steps, the screw 104 is rotated by starting the motor 105, which in turn drives the sealing plate 106 to move back and forth on the inner wall of the second tank 103, blocking the heat dissipation hole 102 and keeping the internal space of the protective box 1 sealed. After a period of time, the electronic components inside the protective box 1 raise the internal temperature of the protective box 1 by the heat they emit. Under the blowing of the fan 101, the hot air circulates inside the protective box 1, drying the internal moisture and preventing excessive moisture from damaging the circuit board 4. Then, the screw 104 reverses and drives the sealing plate 106 to release the seal. Under the action of the fan 101, the accumulated hot air inside is discharged, solving the problem that the sealing ring may lose its sealing effect due to oxidation. Due to the lack of an active dehumidification device, moisture may seep into the equipment, causing short circuits or corrosion.
