Technical Field

[0001] The utility model relates to the technical field of door bodies, in particular to an automatic door for steam sterilization in a laboratory. Background Art

[0002] In the laboratory, in order to improve the sanitary environment of the laboratory, the laboratory is generally sterilized regularly to prevent bacteria from invading the interior of the laboratory. Currently, the existing laboratory doors are automatic doors, which not only have a high degree of automation but also have good sealing. However, the existing automatic doors used in laboratories lack the structure of automatic sterilization.

[0003] Patent publication number "CN218234797U" discloses "a kind of automatic door for laboratory steam sterilization, including a door frame, both ends of one side of the inner part of the door frame are installed with fixed plates, and two electric telescopic rods are installed on one side of the inner part of the door frame, one end of the electric telescopic rod is connected to a connecting plate, and the first mounting plate and the second mounting plate can be moved by utilizing the movable door during the activity, so that when the movable door is closed, the conductive block can be inserted into the conductive joint, so that the circuit of the electric control board is connected, and the nozzle sprays steam for sterilization. When the movable door is opened, the conductive block and the conductive joint can be separated, so that the circuit of the electric control board can be disconnected, so that the nozzle stops spraying steam, and the possibility of scalding when people pass by can be prevented, thereby realizing the automatic sterilization function of the device."

[0004] In response to the above-mentioned related issues, when the existing steam sterilization automatic door is sterilizing, the high-temperature steam may condense into water droplets on the surface of the door body. Since no water removal structure is set, the water droplets generated during use will flow to the ground, causing the ground to be wet and slippery. Therefore, there is a problem of inconvenience in collecting the water droplets on the surface of the door body.

[0005] Therefore, the utility model provides a laboratory steam sterilization automatic door to solve the above problems. Utility Model Content

[0006] In view of the shortcomings of the prior art, the utility model provides an automatic door for steam sterilization for laboratories, which solves the problem that during sterilization, high-temperature steam may condense into water droplets on the surface of the door body of the existing steam sterilization automatic door. Since no water removal structure is provided, the water droplets generated during use will flow to the ground, causing the ground to be wet and slippery, and therefore it is inconvenient to collect the water droplets on the surface of the door body.

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: a laboratory steam sterilization automatic door, comprising a shell, the inner side of the shell is slidably connected with an opening and closing mechanism, the opening and closing mechanism includes a switch button embedded in the outer surface of the shell, and the inner wall of the shell is fixedly connected with a sterilization mechanism, the sterilization mechanism includes a nozzle and a scraper fixedly connected to the inner wall of the shell.

[0008] Furthermore, a water collecting trough is provided on the inner side surface of the shell, a drainage valve is fixedly connected to the inner side surface of the water collecting trough, a fixing column is fixedly connected to the inner wall of the water collecting trough, and an alarm is fixedly connected to the outer surface of the shell.

[0009] By adopting the above technical solution, the waste water in the sump can be easily collected through the drainage valve.

[0010] Furthermore, a baffle is fixedly connected to the outer surface of the shell, the outer surface of the baffle is fixedly connected to the outer surface of the nozzle, and a vent is provided on the outer surface of the shell.

[0011] By adopting the above technical solution, the steam escape from the inner side of the shell can be reduced by the baffle, thereby improving the steam sterilization effect.

[0012] Furthermore, the sterilization mechanism also includes a plurality of groups of resistance heating rods, and the resistance heating rods are fixedly connected to the inner side surface of the shell.

[0013] By adopting the above technical solution, the moisture on the outer surface of the door body can be dried conveniently by using the resistance heating rod.

[0014] Furthermore, the inner wall of the shell is fixedly connected to a waterproof frame, the inner side surface of the waterproof frame is fixedly connected to a motor, the output shaft of the motor passes through the outer surface of the waterproof frame and is fixedly connected to a threaded rod, the other end of the threaded rod is rotatably connected to the inner side surface of the shell, and the inner wall of the shell is fixedly connected to a slide rail.

[0015] By adopting the above technical solution, water vapor can be prevented from entering the motor through the waterproof frame.

[0016] Furthermore, a connecting block is threadedly connected to the outer surface of the threaded rod, a lower surface of the connecting block is fixedly connected to the upper surface of the door body, and an outer surface of the connecting block is slidably connected to the upper surface of the slide rail.

[0017] By adopting the above technical solution, the door body can be easily limited by the slide rail, so that the door body can be stably slid into the shell.

[0018] Beneficial Effects

[0019] The utility model provides a laboratory steam sterilization automatic door. Compared with the prior art, it has the following beneficial effects:

[0020] 1. The laboratory uses steam to sterilize automatic doors. By starting the nozzle, the nozzle sprays steam, which makes it easier to sterilize the outer surface of the door. When the door slides on the inner side of the shell, the scraper can scrape the condensed water droplets on the outer surface of the door into the sump, and then start the drain valve to collect the sewage. At the same time, the resistance heating rod can heat the door. On the one hand, it can evaporate the moisture on the outer surface of the door, and on the other hand, it can perform secondary disinfection on the door.

[0021] 2. The laboratory uses steam sterilization automatic doors. By stepping on the switch button, the motor is started. The output shaft of the motor drives the threaded rod to rotate. The rotation of the threaded rod drives the connecting block to slide along the outer surface of the slide rail, so that the door body can slide on the inner side of the shell to open and close the door body, avoiding the situation of manually holding the handle to open the door, reducing the risk of cross infection.
