[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0031] like Figures 1 to 3As shown, the handrail cleaner according to the first embodiment of the invention includes a cleaning module 100 and a handle 200. The cleaning module 100 includes a mounting body 110, a liquid storage box 120 and two cleaning parts 130. The liquid storage box 120 is arranged on the mounting body 110, and the liquid storage box 120 is used to store cleaning liquid. In order to control the outflow of the cleaning liquid, the liquid storage box 120 is built with an electric water valve (not shown in the drawings), and the electric water valve can be a solenoid valve. The electric water valve is connected to a water outlet pipe 310. A nozzle 300 is provided at the bottom of the mounting body 110. The nozzle 300 is connected to the electric water valve through the water outlet pipe 310. When the electric water valve is started, the cleaning liquid in the liquid storage box 120 can be diverted to the nozzle 300 and then flows out from the nozzle 300. It can be understood that the nozzle 300 can also be arranged on the cleaning part 130, but is not limited thereto.

[0032] like Figures 4 to 6 As shown, the two cleaning parts 130 are movably connected to the two sides of the installation body 110, so that the distance between the two cleaning parts 130 is adjustable, and a cleaning space 140 is provided between the two cleaning parts 130. The shape of the cleaning space 140 corresponds to the shape of the handrail, and the spray direction of the nozzle 300 points to the cleaning space 140; if the shape of the handrail is cylindrical, the shape of the cleaning space 140 is circular, and the shapes of the two cleaning parts 130 are both arc-shaped, and the inner diameters of the two are consistent; if the shape of the handrail is square tube-shaped, the shape of the cleaning space 140 is rectangular, and the shapes of the two cleaning parts 130 are both right-angled, and the inner widths of the two are consistent. Since the two cleaning parts 130 are movably connected to the two sides of the installation body 110, and the shape of the cleaning space 140 corresponds to the shape of the handrail, the handrail cleaner can adapt to stair handrails of different sizes.

[0033] like Figure 4 and Figure 5As shown, specifically, the head ends of the two cleaning parts 130 are each provided with a slider 132, and the tail ends of the two cleaning parts 130 are both overhead ends. The installation body 110 is provided with a sliding opening 111 matched with the slider 132, and each of the sliders 132 can slide in the corresponding sliding opening 111, so that the two cleaning parts 130 are respectively movably connected to the two sides of the installation body 110. In order to enable the two cleaning parts 130 to move synchronously, a gear 400 is installed in the installation body 110, and the two sliders 132 are respectively provided with an upper rack 410 and a lower rack 420, and the gear 400 is meshed with the upper rack 410 and the lower rack 420 at the same time. When the cleaner retracts and retracts any one of the cleaning parts 130, the rack of the cleaning part 130 drives the gear 400 in the installation body 110 to rotate, and then the gear 400 drives the other rack to move, so as to realize the synchronous movement of the two. In order to reduce the situation where the two cleaning parts 130 extend autonomously without external force intervention, the upper rack 410, the lower rack 420 and the gear 400 are all helical teeth, so that the two cleaning parts 130 can be retracted inwardly relatively easily, but extended outwardly relatively difficultly (it is necessary to provide a pulling force for the two cleaning parts 130 to extend outward at the same time), so as to ensure that the two cleaning parts 130 can be close to the armrest.

[0034] In some embodiments of the present invention, in order to prevent the two cleaning parts 130 from being excessively extended so that the slider 132 is separated from the sliding opening 111, a limiting part 401 is provided at the end of the upper rack 410 and the end of the lower rack 420. When the limiting part 401 abuts against the gear 400, the cleaning part 130 cannot continue to extend outward, thereby playing a limiting role.

[0035] like Figure 1 and Figure 3As shown, the inner side of each cleaning part 130 is connected to a cleaning plate 131 for wiping the handrail, and a cleaning cloth or a cleaning brush is provided on the cleaning plate 131, and the cleaning cloth or the cleaning brush is protruding from the cleaning plate 131. When cleaning the handrail, the cleaning cloth or the cleaning brush abuts against the handrail. In order to facilitate the cleaning of the cleaning plate 131, the cleaning plate 131 is snap-connected with the cleaning part 130 so as to disassemble the cleaning plate 131 and clean it. In addition, the handle 200 is provided with a plurality of control buttons 210, one of which is used to control the start and stop of the electric water valve, the handle 200 is built with a battery, the handle 200 is provided with a plug, and the plug is electrically connected to the battery, the installation body 110 is provided with a socket matched with the plug, and the socket is electrically connected to the electric water valve, so that the handle 200 and the installation body 110 are detachably connected, and once the plug is connected to the socket, the battery is electrically connected to the socket. It should be noted that the plug is a multi-pin plug, and all the control buttons 210 on the handle 200 are electrically connected to the corresponding pins in the multi-pin plug, so that when the plug is connected to the socket, the electric water valve can be started and stopped by the control buttons 210 on the handle 200.

[0036] In some embodiments of the present invention, the handle 200 is provided with a charging port or a retractable charging pin, and when the battery needs to be charged, the handle 200 can be removed separately for charging.

[0037] In some embodiments of the invention, in order to improve the cleaning effect of the handrail cleaner, the installation body 110 is built with a vibration motor (not shown in the drawings), the socket is electrically connected to the vibration motor, and the circuit connection method of the vibration motor is similar to that of the electric water valve. When the plug is connected to the socket, the vibration motor can be started and stopped by the control button 210 on the handle 200. When the vibration motor is started, the vibration motor can drive the installation body 110 to vibrate, and transmit the vibration to the two cleaning parts 130 to achieve micro-vibration of the cleaning plate 131.

[0038] like Figure 1 As shown, in some embodiments of the present invention, the liquid storage box 120 is provided with a water inlet, and the water inlet is provided with a flip cover 121. When the cleaning liquid needs to be replenished, the cleaning staff can open the flip cover 121 to inject the cleaning liquid into the liquid storage box 120.

[0039] In some embodiments of the present invention, in order to enable the cleaner to hold the handle 200 tightly, the handle 200 is provided with a plurality of anti-slip grooves; or the handle 200 is provided with a rubber sleeve 220.

[0040] With the above structure, when the armrest needs to be cleaned, first, the two cleaning parts 130 are sleeved outside the armrest, and then the two cleaning parts 130 are retracted inward so that the cleaning cloth or cleaning brush on the cleaning plate 131 is in contact with the armrest. At this time, the cleaner holds the handle 200 to wipe the armrest. If wiping with cleaning liquid is required, the control switch matching the electric water valve is pressed and the electric water valve is started to make the cleaning liquid drip onto the armrest. If stubborn dirt is encountered, the control switch matching the vibration motor is pressed and the vibration motor is started to make the cleaning plate 131 vibrate slightly to improve the cleaning effect of the armrest cleaner.

[0041] It should be further explained that, since the position of the cleaning plate 131 is not adjustable, the cleaner needs to properly rotate the handle 200 when using the armrest cleaner so that the cleaning cloth or cleaning brush on the cleaning plate 131 can fully wipe the outer surface of the armrest.

[0042] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
