However, since most elevators nowadays are contact-based and the handrail structure is mostly fixed and simple, people can easily pick up viruses and spread them to others during the process of entering and exiting. In the current process of concurrent and widespread viral outbreaks, it is easy to achieve infection in the same space and in different spaces. Therefore, in order to reduce the invasion of viruses in the same space, this device provides a contactless elevator start-up and elevator disinfection device, which can reduce the presence of viruses and reduce the risk of infection.

[0003] Therefore, we made improvements and proposed a car voice system. Summary of the Invention

[0018] In a preferred embodiment of the car voice system provided by the present invention, the non-contact sensor button is provided with a non-contact sensing chip inside.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] In the scheme of this application:

[0021] 1. First, connect the connecting ring seat on the external delivery pipe to the outer side of the external discharge cylinder with threads. Then, extend the external delivery pipe to the internal compression sealing disc of the outlet. The sealing disc then compresses the spring, allowing the disinfectant inside the external discharge cylinder to be delivered to the external delivery pipe and spray pipe through the opening on the unclogging cylinder. The booster pump at one end of the external delivery pipe provides suction to allow the liquid to enter the liquid outlet and nozzle on the spray pipe, preventing it from entering the unclogging groove. The electric push rod extends and retracts the sealing disc and spray pipe to disinfect the elevator panel, increasing safety and reducing the retention and presence of viruses.

[0022] 2. When pressing the elevator button, bring your hand close to the non-contact sensor button to activate it. After the signal is processed by the coding inside the elevator panel, the elevator will reach the desired floor. Alternatively, you can bring your hand close to the non-contact sensor button twice to activate the voice recognition module and say the floor number. The signal will then be processed by the elevator panel to take you to the desired floor. This method avoids contact with the switch button, non-contact sensor button, and emergency call button, reducing the chance of simultaneous infection and contact.

[0023] 3. When the car body is finished or needs to be cleaned, disassemble the connecting ring seat and the external delivery pipe to remove the disinfectant cylinder from the external discharge cylinder. Disconnect the handrail through the connecting collar so that one end of the handrail is threadedly connected to the threaded rod. Rotate the rotating ring to drive the connecting rod through the helical gear to adjust the opening angle of the connecting plate. The locking pin is locked in the bayonet. The blocking column extends into the output port and drives the sealing plate to move inward so that the internal disinfectant is delivered to the unblocking groove and then flows to the external colloid.

[0024] 4. The storage slot on the connecting plate can hang items purchased by the owner. The locking pin extends into the inside of the connecting collar and is equipped with a spring. Pulling the connecting collar back and forth can pull out the handrail. When the fixing plate is connected to the connecting collar, the force is downward, so it will not slip out.

[0052] When pressing the elevator button, the hand approaches the non-contact sensor button 122 to activate it. After encoding and signal processing inside the elevator panel 12, the user is directed to the desired floor. Alternatively, the user can approach the non-contact sensor button 122 twice to activate the voice recognition module 123 and speak the floor number. The elevator panel 12 then processes the signal to take the user to the desired floor. This process avoids contact with the switch button 124, non-contact sensor button 122, and emergency call button 125, reducing the chance of simultaneous infection and contact. The switch button 124, non-contact sensor button 122, and emergency call button 125 are all equipped with sensor chips.

[0053] Example 2

[0054] The storage component includes a disinfectant reservoir 117, and an external discharge reservoir 11 with a hinged cover 111. The top side of the cover 111 has a handle groove 112, and the cover 111 and the external discharge reservoir 11 have corresponding locking slots for engagement. The sealing component includes an outlet 11701 and a sealing disc 11702. The outlet 11701 has a drain tube 11706 located inside the disinfectant reservoir 117. The drain tube 11706 has openings 11704 arranged in a circumferential array on its surface. A sealing ring 118 is located at the outer port of the outlet 11701, and a spring 11703 is located inside the drain tube 11706. The disinfection component includes a connecting ring seat 114, with an external discharge pipe 115 inside. A booster pump 119 is installed inside one end of the external discharge pipe 115. The output end of the booster pump 119 has a spray nozzle 116, and the upper surface of the spray nozzle 116 has a placement groove 11601. An electric push rod 11602 is installed on the top side of one end of the external delivery pipe 115, and the placement groove 11601 is set inside the placement groove 11601. A liquid outlet head 1110 is installed at one end of the spray pipe 116. A nozzle 1112 is opened on the surface of the liquid outlet head 1110, and a sealing plate 1111 is provided at one end of the liquid outlet head 1110.

[0055] First, the connecting ring seat 114 on the external delivery pipe 115 is threaded to the outer side of the external discharge tube 11. Then, the external delivery pipe 115 extends to the internal compression sealing plate 11702 of the output port 11701. Then, the sealing plate 11702 compresses the spring 11703, so that the disinfectant inside the external discharge tube 11 is delivered to the external delivery pipe 115 and the spray pipe 116 through the opening 11704 on the unblocking tube 11706. The booster pump 119 at one end of the external delivery pipe 115 provides suction to make the liquid enter the liquid outlet head 1110 and the nozzle 1112 on the spray pipe 116, and will not enter the unblocking groove 11707. The electric push rod 11602 extends and retracts the sealing plate 1111 and the spray pipe 116 inside the placement groove 11601 to disinfect the elevator panel 12. When not disinfecting, the sealing plate 1111 and the elevator panel 12 are set horizontally and sealed.

[0056] The sealing tray 1111 is set around the elevator panel 12 so that the surface can be disinfected. It can also be extended and retracted to facilitate the removal and insertion of the disinfectant bottle 117, thereby increasing safety and reducing the retention and presence of viruses.

[0057] Example 3

[0058] The mounting structure includes a limiting slot with a locking pin 13202 inside. One end of the locking pin 13202 has a connecting collar 132, and the connecting collar 132 has a compression spring 13201 inside. The compression spring 13201 extends into the interior of the fixing plate 13. The connecting collar 132 is slidably mounted with the fixing plate 13. One end of the connecting collar 132 has a support rod 131 inside. The outer cylinder 11 has a drainage groove 11707 inside, which penetrates the disinfectant cylinder 117. The connecting structure includes a threaded rod 133 with a rotating ring 134 rotatably mounted on its bottom side. One end of the rotating ring 134 extends into the interior of the threaded rod 133 and has a connecting rod 13301. A threaded seat 13302 is mounted on the top wall of the threaded rod 133, and a helical gear 13303 is meshed with the surface of the connecting rod 13301. The fixing structure includes a connecting plate 136, a storage groove 135 is provided on the surface of the connecting plate 136, a blocking post 138 is provided on the bottom side of both ends of the connecting plate 136, and a locking pin 137 is provided on both ends of the bottom side of the connecting plate 136.

[0059] When the interior of the car body 1 is finished or needs to be cleaned, disassemble the connecting ring seat 114 and the external delivery pipe 115, so that the disinfectant cylinder 117 can be taken out from the external discharge cylinder 11. Move the handrail 131 towards each other through the connecting sleeve 132, so that the locking pin 13202 is disengaged from the buckle, so that the inner end of the handrail 131 is threadedly connected to the outer surface of the threaded rod 133. Rotate the rotating ring 134 to drive the connecting rod 13301 to adjust the opening angle of the connecting plate 136 through the helical gear 13303. The locking pin 137 is locked on the locking slot 11705. The blocking column 138 extends into the output port 11701, driving the sealing plate 11702 to move inward, so that the internal disinfectant is delivered to the unblocking groove 11707 and then flows to the outer colloid 113. Manually hold the handrail 131 to make the outer colloid 113 roll and clean the inner wall of the car body 1. The sealing ring 118 and the output port 11701 are rotated and set.

[0060] It can be transformed into a different form for cleaning the inner walls, thereby increasing the function and transforming the form of the handrail 131, so that it can not only disinfect but also clean and sweep the car body 1.

[0061] The principle is as follows: First, the disinfectant cylinder 117 is placed into the external discharge cylinder 11. Then, the connecting ring seat 114 on the external discharge pipe 115 is threadedly connected to the outer side of the external discharge cylinder 11. After that, the external discharge pipe 115 extends to the inside of the outlet 11701 and squeezes the sealing disc 11702. Then, the sealing disc 11702 squeezes the spring 11703, so that the disinfectant inside the external discharge cylinder 11 is delivered through the opening 11704 on the drain cylinder 11706 to the external discharge pipe 115 and the spray pipe 116. The booster pump 119 at one end of the external discharge pipe 115 provides suction to make the liquid enter the outlet head 1110 and the nozzle 1112 on the spray pipe 116, and will not enter the drain trough. Inside 11707, the electric push rod 11602, within the placement slot 11601, extends the sealing disc 1111 and spray pipe 116 to disinfect the elevator panel 12. When not disinfecting, the sealing disc 1111 and elevator panel 12 are horizontally sealed. When cleaning the interior of the car body 1 is required, the connecting ring seat 114 and external delivery pipe 115 are disassembled, allowing the disinfectant cylinder 117 to be removed from the external delivery cylinder 11. The handrail 131 is moved towards each other through the connecting collar 132, causing the locking pin 13202 to disengage from the buckle, making the inner end of the handrail 131 threadedly connected to the outer surface of the threaded rod 133. Rotating the rotating ring 134 drives the connecting rod 13301 through the inclined... Gear 13303 adjusts the opening angle of connecting plate 136, locking pin 137 engages with slot 11705, blocking column 138 extends into outlet 11701, driving sealing disc 11702 inward to deliver internal disinfectant to unblocking channel 11707 and then onto outer colloid 113. Manually holding handle 131 causes outer colloid 113 to roll and clean the inner wall of car body 1. Sealing ring 118 rotates with outlet 11701. Storage slot 135 on connecting plate 136 can hang items purchased by the owner. Locking pin 13202 extends into connecting collar 132 and is equipped with a spring; connecting collar 132 can be pulled back and forth. When the handrail 131 is pulled out and the fixing plate 13 is connected to the connecting collar 132, the force is downward, so you will not slip out. When pressing the elevator button, your hand is close to the non-contact sensor button 122 to activate it and make it powered on. After the encoding and signal processing inside the elevator panel 12, it will reach the floor. Alternatively, you can bring your hand close to the non-contact sensor button 122 twice to activate the voice recognition module 123 and say the floor number. The signal processing through the elevator panel 12 will make it reach the desired floor. Avoiding contact with the switch button 124, non-contact sensor button 122, and emergency call button 125 reduces the chance of simultaneous spatial infection and contact.
