Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Refer to Figure 1 , Figure 3 and Figure 5 , an embodiment provided by the present invention: An outbound call display with sound and light prompts, including a plastic frame 1, a panel 3 is fixedly connected to the front side of the plastic frame 1, an LCD color screen 5 is fixedly connected to the top of the inner wall of the plastic frame 1, a button 4 is fixedly connected to the bottom of the inner wall of the plastic frame 1, an electric telescopic rod 6 is fixedly connected to the middle of the rear side of the plastic frame 1, one end of the electric telescopic rod 6 is fixedly connected to an L-shaped hollow plate 7, a liquid storage box 16 is fixedly connected to the left side of the rear part of the plastic frame 1, a liquid inlet pipe 18 communicates with the top of the liquid storage box 16, a liquid outlet pipe 17 communicates with the right side of the liquid storage box 16, a plug rod 11 is fixedly connected to the right side of the liquid outlet pipe 17, a cover plate 12 is rotatably connected to the right side of the plug rod 11, a pulling bar 10 is rotatably connected to the left side of the plug rod 11, a motor 8 is fixedly connected to the right side of the rear part of the plastic frame 1, a rotating bar 9 is fixedly connected to one end of the motor 8, the rotating bar 9 is rotatably connected to the pulling bar 10, a cylinder 13 is fixedly connected to the top right part of the rear end of the plastic frame 1, the cylinder 13 is slidably connected to the plug rod 11, a drain pipe 14 communicates with the right side of the cylinder 13, the top of the drain pipe 14 penetrates through the L-shaped hollow plate 7 and communicates with an atomizing nozzle 15, a clamping mechanism 2 is arranged on the rear side of the plastic frame 1, and the clamping mechanism 2 is used for quickly disassembling and installing the device;

[0033] Specifically, it is set that after the operation and when the personnel leave the elevator, the electric telescopic rod 6 is started at this time, which can drive the L-shaped hollow plate 7 to extend out of the plastic frame 1. Subsequently, the motor 8 is started to drive the rotating bar 9 to rotate. Then, the rotation of the rotating bar 9 can drive the pulling bar 10, and further drive the plug rod 11 to move reciprocally. When the plug rod 11 moves to the left side of the cylinder 13, the cover plate 12 will rotate and open. At this time, the disinfectant in the liquid storage box 16 will enter the cylinder 13 through the liquid outlet pipe 17 under its own gravity. When the plug rod 11 moves to the right side, the cover plate 12 will close under the block of the disinfectant, thus forming a sealed space. Under the action of the plug rod 11, the disinfectant will enter the atomizing nozzle 15 through the drain pipe 14, and then spray out gas to disinfect and sterilize the surrounding of the equipment. When it is completed, the operation of the motor 8 is stopped, and the electric telescopic rod 6 is started to contract, thus completing the disinfection operation.

[0034] Referring to Figure 1 、 Figure 4 and Figure 5 As shown in, the engaging mechanism 2 includes a fixing plate 201, which is arranged at the rear side of the plastic frame 1. Slots 205 are opened on the left and right sides of the rear part of the plastic frame 1. L-shaped clamping blocks 202 are fixedly connected to the left and right sides of the front part of the fixing plate 201. The L-shaped clamping blocks 202 are engaged with the slots 205. A limiting hole 204 is opened at the bottom of the plastic frame 1. A limiting column 203 is fixedly connected to the bottom of the front side of the fixing plate 201. The limiting column 203 is engaged with the limiting hole 204. Grooves 206 are opened on the left and right sides of the outer wall of the plastic frame 1.

[0035] Specifically, the L-shaped clamping blocks 202 can be engaged with the slots 205, so that the whole device can be firmly attached to the fixing plate 201. And under the engagement of the limiting column 203 and the limiting hole 204, the device can be supported by the fixing plate 201. When disassembly and maintenance are required, just grab the groove 206 and then move upward to the top of the fixing plate 201 to release the engagement between the limiting column 203 and the limiting hole 204. Then move forward to the front side of the fixing plate 201 to remove the device, thus facilitating the maintenance personnel to carry out maintenance.

[0036] Referring to Figure 1 、 Figure 2 and Figure 4 As shown in, a transparent plate 19 is fixedly connected to the top side of the front part of the panel 3. Direction grooves 20 are opened on the upper and lower sides of the front part of the panel 3. Color lights 21 are fixedly connected to the inner walls of the direction grooves 20. A fixing block 22 is fixedly connected to the bottom of the front side of the panel 3. A nameplate 23 is fixedly connected to the front side of the fixing block 22. A camera 24 is fixedly connected to the front side of the plastic frame 1. A heat sensor 25 is fixedly connected to the right side of the plastic frame 1.

[0037] Specifically, the liquid crystal color screen 5 can be protected by the transparent plate 19. Through the direction grooves 20 and the colored lights 21, the operating state of the elevator can be indicated by the illumination of the colored lights 21. The basic information of the device can be marked through the nameplate 23. Face recognition can be performed through the camera 24, thereby preventing strangers from entering. Whether someone enters the elevator can be identified through the heat sensor 25.

[0038] Refer to Figure 1 、 Figure 2 and Figure 4 The top of the liquid inlet pipe 18 is fixedly connected with a water injection port 26. A rubber plug 27 is arranged on the inner wall of the water injection port 26. Sound holes 28 are respectively opened on the left and right sides of the top of the outer wall of the plastic frame 1. Speakers 29 are fixedly connected to the left and right sides of the rear inner wall of the plastic frame 1. Light bars 30 are fixedly connected to the left and right sides of the front part of the plastic frame 1. A transparent frame 31 is fixedly connected to the outer wall of the panel 3.

[0039] Specifically, the addition of disinfectant can be facilitated through the water injection port 26. When the elevator arrives at the station, passengers can be reminded through the sound holes 28 and the speakers 29, and passengers are reminded to pay attention to safety. Through the light bars 30 and the transparent frame 31, when the elevator ascends or descends, it can flash along the corresponding direction. Passengers only need to see the gradual change direction of the light bars 30 to know whether the elevator has arrived at the station or is ascending or descending.

[0040] Working principle: Before using this device, first, after the operation program is started and the personnel have left the elevator, the electric telescopic rod 6 is immediately started, so that the L-shaped hollow plate 7 extends out of the plastic frame 1. Subsequently, the motor 8 is started to drive the rotating bar 9 to rotate, and the rotation of the rotating bar 9 drives the pulling bar 10, thereby enabling the plug rod 11 to perform a reciprocating motion. When the plug rod 11 moves to the left side of the cylinder 13, the cover plate 12 rotates and opens accordingly. At this time, the disinfectant in the liquid storage box 16 flows into the cylinder 13 through the liquid outlet pipe 17 under the action of gravity. When the plug rod 11 moves to the right side, the cover plate 12 closes under the blocking action of the disinfectant, forming a closed space. Under the push of the plug rod 11, the disinfectant flows into the atomizing nozzle 15 through the drain pipe 14 and is sprayed out to disinfect and sterilize the surrounding of the device. After the disinfection operation is completed, the motor 8 stops running, and the electric telescopic rod 6 is started to contract, thus ending the disinfection process.

[0041] And through the clamping mechanism 2, with the cooperation of the L-shaped clamping block 202 and the clamping groove 205, the device can be attached to the fixing plate 201. At the same time, under the interaction of the limiting column 203 and the limiting hole 204, the device obtains the supporting force of the fixing plate 201. When disassembly and maintenance are required, just hold the groove 206 and move it upward to the top of the fixing plate 201, then the locking state between the limiting column 203 and the limiting hole 204 can be released. Subsequently, move the device to the front side of the fixing plate 201, and the device can be easily removed, thus facilitating the maintenance personnel to carry out the maintenance work.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
