Description
Technical Field
[0001] This utility model relates to the field of intercom device technology, specifically to an intercom device for visitors. Background Technology
[0002] Currently, in residential communities, companies, or detached houses, access barriers are installed at the entrances for security management purposes. These barriers can be opened with either a key or an intercom. When a visitor or an insider without a key wants to enter through the barrier, they can call the room via the intercom. After confirmation from the person inside, the person inside can remotely unlock the barrier, allowing the visitor to pass.
[0003] Existing intercom devices are mostly installed on the outside of the unit door, and their positions are relatively fixed. However, since the residents include the elderly and children, it is difficult for children to operate the intercom device due to their short stature. This results in low ease of use for the intercom device. In addition, the intercom device is easily affected by dust and rain when exposed to the outside for a long time, which can easily damage the internal components and shorten its service life.
[0004] Therefore, it is necessary to invent a visitor intercom device to solve the above problems. Utility Model Content

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0031] This utility model provides, for example Figures 1 to 4 The illustrated intercom device for visitors includes a mounting base 1. A protective shell 12 is fixedly connected to the upper front side of the mounting base 1. A liftable viewing panel 2 is provided on the front side of the mounting base 1. A lifting mechanism is provided between the mounting base 1 and the viewing panel 2. The lifting mechanism includes a positioning groove 13, a lifting screw 14, a servo motor 15, a positioning block 21, and a connecting block 22. Mounting plates 11 are fixedly connected to both the left and right surfaces of the mounting base 1. Control buttons are fixedly connected to the upper and lower ends of the surface of the left mounting plate 11. Button 18, two sets of positioning grooves 13 are provided on the right side surface of the mounting base 1, the upper and lower ends of the lifting screw 14 are rotatably connected to the inner top wall and inner bottom wall of the mounting base 1 respectively, the servo motor 15 is fixedly installed on the upper end of the mounting base 1, the output end of the servo motor 15 is fixedly connected to the upper end of the lifting screw 14, the positioning block 21 is fixedly connected to the back of the visible panel 2, the connecting block 22 is fixedly connected to the back of the positioning block 21, the positioning block 21 is slidably connected to the positioning groove 13, and the connecting block 22 is threadedly connected to the lifting screw 14.
[0032] The servo motor 15 can rotate in both directions. The output of the servo motor 15 drives the lifting screw 14 to rotate. During the rotation of the lifting screw 14, the connecting block 22 moves up and down inside the mounting base 1, thereby moving the visible panel 2 up and down to adjust the height of the visible panel 2. At the same time, the control button 18 is provided with two buttons, one on top and one on the bottom. The top button is convenient for adults to use, while the bottom button is convenient for children, people with short stature, and people with disabilities to use.
[0033] Specifically, during use, pressing the control button 18 starts the servo motor 15. The servo motor 15 rotates forward, driving the lifting screw 14 to rotate forward. With the cooperation of the positioning block 21, it drives the connecting block 22 to move downward on the surface of the lifting screw 14. At the same time, it drives the positioning block 21 and the viewing panel 2 to move downward. After adjusting the viewing panel 2 to a suitable height, the control button 18 is released. In addition, the call is completed through the viewing panel 2. After the access control is opened, the servo motor 15 automatically starts and rotates in the reverse direction, driving the lifting screw 14 to rotate in the reverse direction, retracting the viewing panel 2 into the protective shell 12. The protective shell 12 protects the viewing panel 2, improving the safety of the viewing panel 2 and preventing it from being affected by dust and rain, as well as preventing human damage.
[0034] See Figure 1 , Figure 2 and Figure 5The mounting base 1 has a liquid storage tank 3 fixedly connected to the upper part of the front and rear sides. The upper surfaces of the two sets of liquid storage tanks 3 are fixedly connected to the liquid outlet pipe 31 and the liquid inlet pipe 36. The front end of the liquid inlet pipe 36 is fixedly connected to the liquid inlet hopper 37. The upper end of the protective shell 12 is fixedly installed with a micro pump body 32. The two sets of liquid outlet pipes 31 are fixedly connected to the liquid inlet of the micro pump body 32. The liquid outlet of the micro pump body 32 is fixedly connected to the liquid outlet pipe 33. The lower end of the liquid outlet pipe 33 is fixedly connected to the liquid spraying pipe 34. The surface of the liquid spraying pipe 34 is fixedly connected to the liquid nozzle 35. The liquid spraying pipe 34 is fixedly connected to the inner wall of the protective shell 12. The upper ends of the mounting base 1, the protective shell 12 and the liquid storage tanks 3 are fixedly connected to the equipment shell 16. The front end of the equipment shell 16 is snapped with a movable panel 17. The surface of the movable panel 17 has multiple heat dissipation grooves.
[0035] Simultaneously, as the servo motor 15 drives the visible panel 2 to move upward, the micro pump 32 starts, drawing out the disinfectant alcohol from the storage tank 3 through the outlet pipe 31 and transporting it to the inside of the spray pipe 34 through the drain pipe 33. At this time, the disinfectant alcohol is sprayed outward in a mist through multiple spray nozzles 35 on the surface of the spray pipe 34. As the visible panel 2 moves to the protective shell 12, the mist alcohol is sprayed on the surface of the visible panel 2, disinfecting and sterilizing the surface of the visible panel 2, reducing the spread of bacteria and improving the safety of use.
[0036] In addition, when the disinfectant alcohol inside the storage tank 3 is used up, remove the movable panel 17 to expose the two sets of inlet hoppers 37 inside, pour the alcohol into the inlet hoppers 37, and then the alcohol flows into the storage tank 3 through the inlet pipe 36 for storage.
[0037] The working principle of this utility model is as follows: By utilizing the servo motor 15, lifting screw 14, positioning block 21, and connecting block 22, the height of the visual panel 2 is adjusted. In use, the visual panel 2 is moved downward to a specified height to facilitate use by people of different heights and improve ease of use. In the non-use state, the visual panel 2 is raised to the inside of the protective shell 12, and the protective shell 12 protects the visual panel 2, reducing the impact of dust and rain on the visual panel 2 and improving the safety of equipment use. At the same time, the micro pump body 32 and the spray nozzle 35 work together to spray disinfectant alcohol outward to disinfect and sterilize the surface of the visual panel 2, reduce the spread of bacteria, and improve the safety of use.
