Description

Technical Field

[0001] The invention relates to the technical field of clean room door handle devices. Background Art

[0002] Clean room purification doors are used in clean rooms with relatively high cleanliness requirements, especially those that require good sealing and easier cleaning. However, with the continuous development of technology, people's requirements for purification doors are getting higher and higher, resulting in traditional purification doors can no longer meet people's needs.

[0003] The existing clean room purification door has certain disadvantages when in use. Since there are many people entering and leaving the clean room, they will frequently touch the door handle of the clean room purification door, which will cause the bacteria and viruses on their hands to be brought to the surface of the door handle, so that people who touch the door handle subsequently carry bacteria and viruses, causing subsequent people who touch the door handle to be infected, especially during the virus epidemic, this situation is more serious, and the existing door handle cannot disinfect and sterilize the door handle in real time. Summary of the invention

[0004] The object of the present invention is to provide a clean room door handle to overcome the defect that the door handle cannot be disinfected and sterilized in time.

[0005] The technical solution to achieve the above-mentioned purpose is: a clean room door handle, including a door body, a door handle body is rotatably arranged on the outer wall of the door body, the upper end of the door handle body is arranged as an inclined surface, a delay sensing switch is embedded in the top of the door handle body, a micro fan is fixedly connected to the outer wall of the door handle body, a storage box is fixedly connected to the outer wall of the door body, a discharge pipe is fixedly connected to the bottom end of the storage box, the outlet end of the discharge pipe faces the highest point of the inclined surface, a round rod is slidably connected to the top end of the storage box, and the The bottom end of the round rod is fixedly connected with a baffle, and the baffle is located just above the top end of the discharge pipe, the top end of the round rod is fixedly connected with a connecting rod, the bottom end of the connecting rod is fixedly connected with a linear rack, the outer wall of the storage box is fixedly connected with a driving member, the outer wall of the storage box is fixedly connected with a fixed block, the inner wall of the fixed block is rotatably connected with a rotating shaft, the inner wall of the rotating shaft is fixedly connected with a rotating rod, the outer wall of the rotating rod is fixedly connected with an arc rack, the outer wall of the door handle body is fixedly connected with a push plate, and the push plate is located below one end of the rotating rod.

[0006] Preferably, the air outlet end of the micro fan faces the top of the door handle body, and the delay sensing switch is electrically connected to the micro fan.

[0007] Preferably, the length of the discharge pipe is equal to the width of the door handle body.

[0008] Preferably, the driving member includes a support plate, a circular shaft, a driving gear and a driven gear, the outer wall of the storage box is fixedly connected to two support plates, the outer wall of the support plate is rotatably connected to a circular shaft, one end of the circular shaft is fixedly connected to the driving gear, and the other end of the circular shaft is fixedly connected to the driven gear, the driving gear is meshed with a circular arc rack, and the outer wall of the driven gear is meshed with a linear rack.

[0009] Preferably, a transparent glass plate is installed on the outer wall of the storage box, an inlet pipe is fixedly connected to the top of the storage box, and a sealing cover is threadedly connected to the inner wall of the top of the inlet pipe.

[0010] Preferably, the inner wall of the discharge pipe is rotatably connected to a coupling shaft, and the outer wall of the coupling shaft is fixedly connected to four buffer plates distributed in an array.

[0011] Preferably, a spring is fixedly connected to the top of the storage box, and a top of the spring is fixedly connected to a connecting rod.

[0012] Preferably, a filter screen is inserted and connected to the bottom end of the discharge pipe, and the width of the bottom end of the discharge pipe is 5 mm.

[0013] The beneficial effect of the present invention is that holding and rotating the door handle body will trigger the delayed sensing switch, so that the micro fan starts for a period of time. At the same time, the door handle body drives the push plate to move upward, and the push plate pushes one end of the rotating rod to rotate upward, so that the other end of the rotating rod rotates downward, and the rotating rod drives the other end to drive the arc rack to drive the driving member to operate, and the driving member drives the linear rack to move upward, and the linear rack drives the connecting rod to move upward. At the same time, the connecting rod pulls the spring, and the connecting rod drives the round rod to move upward, so that the baffle is separated from the top opening of the discharge pipe, so that the disinfectant is input into the outer wall of the door handle body through the discharge pipe. The disinfectant will push the buffer plate by its own gravity, and the buffer plate will intermittently block the discharge pipe to avoid excessive discharge of the disinfectant. The upper end of the door handle body is set as an inclined surface, so that the disinfectant can flow along the inclined surface to the outer wall of the entire door handle body that is held, thereby disinfecting the surface of the door handle body that is held. At the same time, the micro fan accelerates the flow of the disinfectant and accelerates the volatilization of the disinfectant, so as to avoid the door handle body from being kept in a wet state for a long time, thereby realizing the timely disinfection of the door handle body.
