The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0041] The elevator handrail 20 claimed in the present application is installed on the elevator car 100 and used for disinfecting the internal environment of the elevator car 100.
[0042] As Figure 1 , Figure 2As shown, the elevator handrail 20 provided by the embodiment of the present application has a cavity 201 formed inside the elevator handrail 20, which is used to contain the disinfectant 200; the elevator handrail 20 is provided with an atomization mechanism 30, which can atomize the disinfectant 200 in the cavity 201 and generate disinfectant gas when working, and the atomization mechanism 30 can discharge the generated disinfectant gas into the elevator car 100. Here, the disinfectant gas is in a gaseous state, and the disinfectant gas discharged by the atomization mechanism 30 can diffuse into the interior of the elevator car 100.
[0043] It can be understood that the disinfectant 200 contained in the cavity 201 of the elevator handrail 20 is atomized by the atomization mechanism 30 on the elevator handrail 20, and the disinfectant gas generated after atomization is discharged into the elevator car 100, and by using the material characteristics of the disinfectant gas, the interior environment of the elevator car 100 can be disinfected, so that the interior space of the elevator car 100 can be disinfected, which not only makes the entire disinfection process more simple and efficient, but also improves the interior hygiene level of the elevator car 100 and saves the cost of manual disinfection. Here, the atomization mechanism 30 is arranged on the part of the elevator handrail 20 connected to the car wall 10 on the elevator car 100. It should be noted that the elevator handrail 20 can be adjusted in style according to customer requirements, manufacturer needs, etc. to make the overall structure of the elevator handrail 20 more beautiful. In this embodiment, the atomization mechanism 30 can be any existing atomization device as long as it is connected to the elevator handrail 20 and can contact the disinfectant 200 in the cavity 201.
[0044] As shown in the drawings, Figure 2 In an embodiment, the atomization mechanism 30 includes an atomizer 31 and an atomization pipeline 32, the atomizer 31 is arranged in the cavity 201, and the atomization pipeline 32 communicates with the cavity 201 through the atomizer 31; the atomizer 31 can atomize the disinfectant 200 flowing into the atomizer 31 from the cavity 201 and generate disinfectant gas, and the disinfectant gas can flow to the elevator car 100 through the atomization pipeline 32. By using the structural characteristics of the atomizer 31, the atomization mechanism 30 realizes the atomization of the disinfectant 200 in the cavity 201 of the elevator handrail 20 and generates disinfectant gas when working, and then uses the flow guide of the atomization pipeline 32 to realize the discharge to the elevator car 100. Here, the atomizer 31 is arranged as an ultrasonic atomizing sheet, or other atomizing structures that can atomize the disinfectant into disinfectant gas.
[0045] It can be understood that the atomizing pipe 32 comprises a flow inlet, a flow outlet and a pipe wall connecting the flow inlet and the flow outlet, the flow inlet refers to the opening through which the disinfectant flows into the atomizing pipe 32, and the flow outlet refers to the opening through which the disinfectant gas formed after being atomized by the atomizer 31 flows out of the atomizing pipe 32 to the elevator car 100. The atomizer 31 is arranged at the flow inlet. The atomizing pipe 32 is in communication with the cavity 201 only through the flow inlet, that is, the cavity 201 is in communication with the atomizing pipe 32 only through the flow inlet, and the rest is closed. The disinfectant gas generated after the disinfectant 200 in the cavity 201 is atomized by the atomizer 31 is discharged from the flow outlet to the inside of the elevator car. The flow outlet can be higher than the surface of the elevator handrail 20, or lower than the surface of the elevator handrail 20, or flush with the surface of the elevator handrail 20. In order not to affect the use of the elevator handrail 20, preferably, the flow outlet is not higher than the surface of the elevator handrail 20. Since the processing capacity of the atomizer 31 is limited, preferably, the atomizer 31 is arranged at the bottom of the cavity 201, and then the flow inlet is arranged at the bottom of the cavity 201. Since the entire inside of the elevator handrail 20 is a closed structure, only the flow outlet of the atomizing pipe 32 is connected to the outside air, so that the disinfectant in the atomizing pipe 32 only exists at the flow inlet position, so that less disinfectant contacts the atomizer 31, and the atomizer 31 maintains higher working efficiency.
[0046] Exemplarily, as shown in Figure 2 the flow inlet is located on the wall of the atomizing pipe 32 on the left side of the atomizer 31, and the height direction is slightly higher than the atomizer 31. Since the atomizing pipe 32 is in communication with the outside environment, the cavity 201 is in communication with the outside environment only through the flow inlet. When there is no disinfectant in the atomizing pipe 32, the disinfectant in the cavity 201 will flow to the atomizer 31 in the atomizing pipe 32 from the flow inlet; as the liquid level of the flowing disinfectant gradually rises, the flow inlet will be finally blocked, so that the cavity 201 is closed and cannot enter air, and then there will be a pressure difference between the cavity 201 and the atomizing pipe 32, so that the disinfectant will not continue to flow in, thereby controlling the flow of the disinfectant flowing into the atomizer 31. The height of the flow inlet determines the flow of the disinfectant flowing into the atomizing pipe 32. Preferably, the cavity 201 is first filled with disinfectant to exhaust the air in the cavity 201 and increase the pressure difference between the cavity 201 and the atomizing pipe 32.
[0047] As shown in Figure 2As shown, in an embodiment, the atomization mechanism 30 further comprises a flow guide 33, the flow guide 33 is partially arranged in the atomization pipeline 32, and a flow guide chamber 301 is formed between the flow guide 33 and the atomization pipeline 32, the flow guide chamber 301 is used to guide the disinfectant gas to diffuse to the elevator car 100, in this way, the flow of the disinfectant gas in the atomization pipeline 32 can be facilitated, and the disinfectant gas can be dispersed, so that the disinfection effect of the disinfectant gas on the internal environment of the elevator car 100 can be improved. The flow guide 33 can be arranged in any shape that can guide the disinfectant gas in the atomization pipeline 32 to diffuse in a diffused manner when flowing out of the elevator handrail 20. In an embodiment, the center line of the flow guide 33 is arranged on the same straight line as the center line of the atomization pipeline 32, so that the disinfectant gas can pass through the flow guide chamber 301 in a ring-shaped manner and flow to the elevator car 100. In another embodiment, the flow guide 33 protrudes from the elevator handrail 20, and the part of the flow guide 33 protruding from the elevator handrail 20 gradually increases in outer diameter from the end close to the elevator handrail 20 to the end away from the elevator handrail 20, so as to guide the disinfectant gas to diffuse to the elevator car 100 in an umbrella-shaped manner.
[0048] As shown in Figure 2 and Figure 6 As shown, in an embodiment, the flow guide 33 comprises a flow guide port 331 and a flow guide rod 332, one end of the flow guide rod 332 is fixed in the atomization pipeline 32, the other end of the flow guide rod 332 is connected to the flow guide port 331, and the flow guide port 331 is provided with a through hole penetrating along the extension direction of the flow guide rod 332; the atomization mechanism 30 further comprises a fan 34, the fan 34 is arranged in the through hole and can rotate around the flow guide rod 332, so as to guide the disinfectant gas atomized by the atomizer 31 to the elevator car 100 through the through hole. In this way, after the atomizer 31 located at one end of the atomization pipeline 32 towards the cavity 201 atomizes the disinfectant liquid 200 into disinfectant gas, the fan 34 can promote the disinfectant gas to flow out of the atomizer 31, through the atomization pipeline 32 and to the elevator car, so that the discharge efficiency of the disinfectant gas from the atomization pipeline 32 can be improved, and the disinfection effect of the disinfectant gas on the internal environment of the elevator car 100 can be further improved.
[0049] In this embodiment, under the action of the fan 34, the flow guide chamber 301 formed between the flow guide port 331 and the atomization pipeline 32 becomes an air inlet, and the through hole in the flow guide port 331 becomes an air outlet, thereby promoting the disinfectant gas to diffuse into the elevator car 100.
[0050] It can be understood that whether the fan 34 is arranged or not, the atomizer 31 itself can push the atomized disinfectant gas to the elevator car 100 through the atomization pipeline 32, and the fan 34 only accelerates the flow rate of the disinfectant gas.
[0051] Specifically, in this embodiment, the inside of the guide rod 332 can be used for cable routing of the fan 34. A cable routing space is formed between the inner wall and the outer wall of the elevator handrail 20. The cable of the fan 34 can be extended from the end of the guide rod 332 fixed with the atomizing pipe 32, connected to the controller 50 via the cable routing space of the elevator handrail 20.
[0052] As shown in Figure 2 , in an embodiment, the atomizing mechanism 30 further comprises a partition plate 35 arranged in the cavity 201 and connected with the elevator handrail 20, for separating the cavity 201 into a first chamber 2011 and a second chamber 2012, and the partition plate 35 is provided with a liquid inlet hole 351, and the first chamber 2011 is arranged at a position above the second chamber 2012 along the gravity direction and communicates with the second chamber 2012 through the liquid inlet hole 351.
[0053] In this embodiment, the cavity 201 is separated into two chambers, and the two chambers are only communicated through one liquid inlet hole 351, which can alleviate the flow of the disinfectant in the second chamber 2012, thereby controlling the flow of the disinfectant flowing into the atomizer 31.
[0054] As shown in Figure 4 , Figure 5 , in an embodiment, the atomizer 31 is arranged in the second chamber 2012 and communicates with the second chamber 2012, so that the elevator handrail 20 can be provided with a liquid adding hole 21 at the position of the first chamber 2011, and the liquid adding hole 21 is selectively plugged by a cork 22, so that people can add disinfectant into the first chamber 2011 of the elevator handrail 20 through the liquid adding hole 21, and the disinfectant added into the first chamber 2011 can flow into the second chamber 2012 through the liquid inlet hole 351 of the partition plate 35 and provide disinfectant for the atomizer 31, so that it is convenient to add disinfectant 200 into the elevator handrail 20, and in this process, it is convenient to replace the disinfectant 200 to meet the use demand of disinfecting the internal environment of the elevator car 100.
[0055] As shown in Figure 2 , Figure 3 , in an embodiment, the atomizing mechanism 30 further comprises a floating ball 36 and a trigger switch 37, and the trigger switch 37 is arranged at the bottom of the second chamber 2012 corresponding to the liquid inlet hole 351; the floating ball 36 can float on the disinfectant 200 and move between the liquid inlet hole 351 and the trigger switch 37, and the floating ball 36 can float to block the liquid inlet hole 351 and sink to trigger the trigger switch 37; the atomizer 31 can stop the atomizing operation after the trigger switch 37 is triggered.
[0056] Exemplarily, as shown in Figure 2As shown, the elevator handrail 20 is provided with a grating fence 23 in the area where the second chamber 2012 is located, so as to constrain the movement track of the floating ball 36, and the disinfectant liquid introduced into the second chamber 2012 through the liquid inlet hole 351 can flow to the atomizer 31 through the grating fence 23. In this embodiment, the floating ball 36 is arranged in the space 231 enclosed by the grating fence 23 and the elevator handrail 20, and can float on the disinfectant liquid 200 in the second chamber 2012, and the floating ball 36 can sink or float relative to the grating fence 23 under the driving of the disinfectant liquid in the second chamber 2012. Here, the floating ball 36 is arranged as a rubber ball or a silica gel ball. The floating mechanism 30 can utilize the floating of the floating ball 36 on the liquid surface of the disinfectant liquid in the second chamber 2012, and the floating ball 36 can rise or fall along with the liquid level of the disinfectant liquid in the first chamber 2011, and due to the enclosure of the grating fence 23 to the floating ball 36, the rising floating ball 36 can abut to the position where the liquid inlet hole 351 of the partition plate 35 is located, until the floating ball 36 blocks the liquid inlet hole 351, that is, the floating ball 36 can realize the automatic control of opening and closing of the liquid inlet hole 351 on the partition plate 35, so as to facilitate the control of the disinfectant liquid capacity in the second chamber 2012.
[0057] It can be understood that, as described above, the liquid inlet hole 351 itself can slow down the flow of disinfectant liquid in the second chamber 2012; the opening and closing control of the floating ball 36 to the liquid inlet hole 351 can further enhance the flow control effect. Here, the floating ball 36 does not need to stably block the liquid inlet hole 351, and the existence of the floating ball 36 itself has played a role in further relieving the flow of disinfectant liquid.
[0058] As shown in the drawings, Figure 2 , Figure 3 In this embodiment, the trigger switch 37 is arranged in the space 231 and located at the bottom of the second chamber 2012; wherein the trigger switch 37 can be triggered by the floating ball 36 when the floating ball 36 sinks and generate a feedback signal. Here, the trigger switch 37 is arranged as a micro switch or a proximity switch.
[0059] It can be understood that the triggering of the floating ball 36 by the trigger switch 37 after sinking to the position can realize the signal feedback of the consumption of the disinfectant liquid 200 in the second chamber 2012, so as to play a prompting role to prompt people to timely add disinfectant liquid 200 to the cavity 201 of the elevator handrail 20. At the same time, the damage of the atomizer 31 can be avoided.
[0060] Specifically, the trigger switch 37 is connected to the controller 50 through a cable, and the cable can also be routed through the cable routing space between the inner wall and the outer wall of the elevator handrail 20.
[0061] Understandably, the main function of the float 36 is to trigger the trigger switch 37 when the liquid level drops to a lower position, so as to indicate the addition of disinfectant 200.
[0062] like Figure 2 As shown, in one embodiment, an indicator light strip 38 is provided on the elevator handrail 20. The indicator light strip 38 is electrically connected to a trigger switch 37, and the indicator light strip 38 can illuminate after the trigger switch 37 is triggered. Here, the indicator light strip 38 is located on the elevator handrail 20 at a position parallel to the car wall 10. That is to say, in this embodiment, the elevator car 100 can use the illumination of the indicator light strip 38 to indicate that the disinfectant 200 in the cavity 201 of the elevator handrail 20 has been consumed, thus facilitating the receipt of the signal that the disinfectant 200 in the second chamber 2012 has been consumed. Of course, in other embodiments, a speaker can also be used to indicate that the disinfectant 200 in the second chamber 2012 has been consumed, which will not be elaborated here.
[0063] like Figure 2 As shown, in one embodiment, an ultraviolet lamp 40 is also provided on the elevator handrail 20. The ultraviolet lamp 40 can generate ultraviolet light, which is used to irradiate the elevator car 100. Here, the ultraviolet lamp 40 is also located on the elevator handrail 20 at a position parallel to the car wall 10, so that the elevator car 100 can be disinfected by the ultraviolet light generated when the ultraviolet lamp 40 is working. In this way, the disinfection effect of disinfecting the interior environment of the elevator car 100 can be further improved.
[0064] The ultraviolet lamp 40 is electrically connected to the trigger switch 37, and the ultraviolet lamp 40 can stop or start emitting light after the trigger switch 37 is triggered. In this way, the trigger switch 37 simultaneously controls the start and stop of the ultraviolet lamp 40, so that the ultraviolet lamp 40 and the atomizer 31 stop working synchronously to indicate that the disinfection work has stopped, or so that the ultraviolet lamp 40 starts working after the atomizer 31 stops working, so that the ultraviolet lamp 40 can take over the disinfection work when the disinfectant solution 200 is exhausted.
[0065] like Figure 2 As shown, the elevator car 100 of this application also includes a controller 50. The controller 50 is electrically connected to the atomizer 31, the ultraviolet lamp 40, and the trigger switch 37. The controller 50 can control the working state of the atomizer 31 and the ultraviolet lamp 40 according to the elevator's operating status, and control the working state of the atomizer 31 and the ultraviolet lamp 40 according to the feedback signal sent after the trigger switch 37 is triggered. In other words, the controller 50 controls the operation of the atomizer 31 and the ultraviolet lamp 40 according to the elevator's operating status and the feedback signal sent after the trigger switch is triggered, so that the elevator handrail 20 applied in the elevator car 100 can be automatically disinfected when the elevator car 100 is stopped.
[0066] In summary, the elevator car 100 and the elevator of the present application can use the sterilization gas generated when the atomizing mechanism 30 is working and the ultraviolet light generated when the ultraviolet lamp 40 is working to realize the sterilization operation on the internal environment of the elevator car 100, so that the sterilization of the internal space of the elevator car 100 can be realized, which not only makes the whole sterilization process more simple and efficient, but also improves the internal hygiene level of the elevator car 100, prevents the spread and transmission of pathogens in the elevator, and saves the cost of manual sterilization.
[0067] The technical features of the above embodiments can be combined in any manner, and for the sake of brevity, not all possible combinations of the technical features in the above embodiments are described, but as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present disclosure.
