DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0020] <first embodiment>

[0021] Reference Figure 3 The steam sterilizer 100 is mainly divided into a working module 100a and a control module 100b. The control module and the working module are arranged and fixedly connected along the horizontal direction, and are electrically connected. The working module 100a is mainly responsible for generating steam and sterilizing and disinfecting objects in the cylinder body (not shown in the figure) of the steam sterilizer 100 by using the steam. The control module 100b is mainly responsible for receiving and processing signals of various sensors such as temperature sensors and pressure sensors, accurately controlling the operation of the sterilizer according to a preset program, and ensuring that each operation is orderly. In order to be able to record key parameters such as temperature, pressure, time and the like in the sterilization process in detail, as well as the name of the sterilization program, the information of the operator and the like, and to provide traceable basis for the sterilization process, the control module 100b part of the steam sterilizer 100 in the embodiment is further provided with a printing device 100c. After sterilization is completed, the printing device 100c can print a sterilization report in time, which is convenient for staff to check and archive, and the printed report can be used as an important file for quality control and management in the fields of medical treatment and scientific research. Reference Figure 1The printing device 100c in the embodiment includes a shell 1, a printer (not shown in the figure) and a cover plate 4. The shell 1 is embedded in the control module 100b of the steam sterilizer 100, and has an opening part 1a on one side, through which the inside of the shell 1 is in communication with the outside of the steam sterilizer 100. A control panel 5 is arranged on the inside of the shell 1 close to the opening part 1a, and a circuit device (not shown in the figure) is arranged on the side of the control panel 5 away from the opening part 1a, which is electrically connected with the printer and the steam sterilizer 100 to supply power to the printer and the steam sterilizer 100. A protruding bracket 2 is arranged on the upper surface of the side of the control panel 5 facing the opening part 1a, and the protruding height of the bracket 2 does not exceed the plane of the opening part 1a of the shell 1. The edge part 34 of the bracket 2 is provided with a screw hole, and the edge part 34 is threadedly fixedly connected with the surface of the control panel 5 through a screw 35. In other embodiments, other connection methods can also be used between the control panel 5 and the bracket 2, which are not limited here. The printer (not shown in the figure) is embedded and fixed in the protruding bracket 2, and the printer after being embedded is provided with a printing panel 3 on the side facing the opening part 1a. Figure 1 The surface of the printing panel 3 is provided with a printing port 31 to enable the inside and outside of the printer to communicate, and to enable a paper roll (not shown in the figure) in the printer to be unwound and extended. The printing device 100c further includes a printer switch 32 and a printer indicator lamp 33 arranged on the surface of the side of the printing panel 3 facing the opening part 1a. When the printer switch 32 is started, the printer indicator lamp 33 is immediately turned on, indicating that the printer is powered on and enters a normal working state. The cover plate 4 of the printing device 100c can be opened to cover the opening part 1a. When the cover plate 4 covers the opening part 1a, the printing panel 3 and the control panel 5 are hidden in the shell 1, so that the control module 100b of the steam sterilizer 100 is more simple and beautiful. In addition, when the staff transports, installs or performs other operations on the steam sterilizer 100, the control panel 5 and the printing panel 3 and other precise components in the shell 1 can be physically protected by closing the cover plate 4 to cover the opening part 1a, so as to prevent the printing device 100c or the steam sterilizer 100 from being abnormally operated or damaged due to accidental touch or accidental collision.

[0022] Reference Figure 1The surface of the cover plate 4 is provided with a waist-shaped hole 41. When the printer starts to work, the printing paper is firstly transmitted from the printing port 31, and then transmitted to the outside of the steam sterilizer 100 through the waist-shaped hole 41. When the work report of the steam sterilizer 100 is printed, the staff can directly tear the printing paper from the waist-shaped hole 41 of the cover plate 4 for archiving. In the steam sterilizer 100 with a printer currently sold in the market, there is usually a gap between the cover plate 4 and the printing port 31. When the printer starts to print or the work data of the steam sterilizer 100 is printed again after the previous printing paper is torn off, because the printing paper (not shown in the figure) equipped in the printer is usually curled, when the printing paper is transmitted from the printing port 31, combined with the weight of the printing paper itself, the end of the printing paper is usually transmitted at a horizontal downward angle into the gap between the cover plate 4 and the printing panel 3, so that the printing paper is difficult to directly enter the waist-shaped hole 41 of the cover plate 4 and be transmitted to the outside of the steam sterilizer 100. Therefore, before using the printer to print the report, the steam sterilizer 100 usually opens the cover plate 4 of the printing device 100c, pulls out a certain length of the printing paper in the printer, passes the end of the printing paper through the waist-shaped hole 41 near the side of the printer of the cover plate 4, then closes the cover plate 4 to cover the opening part 1a, and finally starts the printer to start the printing of the work data of the steam sterilizer 100. This printing method makes the staff need to perform multiple preparation operation steps before printing, which seriously affects the work efficiency of the staff and is accompanied by a certain amount of waste of printing paper. In addition, when the cover plate 4 is opened and closed and the printing paper is reset, the risk of the operator accidentally touching the buttons on the control panel 5 and the printing panel 3 is increased, which may cause the printing device 100c or the steam sterilizer 100 to work abnormally or be damaged.

[0023] To avoid the printing paper from the printing port 31 to the gap between the cover plate 4 and the printing panel 3 when the cover plate 4 is in the closed state, the printing paper cannot be directly transmitted from the waist-shaped hole 41 of the cover plate 4. In the embodiment, when the cover plate 4 covers the opening part 1a, the waist-shaped hole 41 is attached to the printing port 31 by setting the protruding height of the bracket 2 relative to the control panel 5, that is, the surface of the cover plate 4 towards the opening part 1a is attached to the surface of the printing panel 3 towards the opening part 1a. This embodiment can ensure that when the printer starts to work, the end of the printing paper is directly pushed into the waist-shaped hole 41 of the cover plate 4 after the printing paper starts to be transmitted from the printing port 31, and the printing paper is transmitted from the waist-shaped hole 41 to the outside of the cover plate 4. Through such an embodiment, when the steam sterilizer 100 starts to work and the printing device 100c starts to print the relevant data of the steam sterilizer 100, it is not necessary to open and close the cover plate 4, and it is not necessary to pull out the printing paper in advance. This embodiment not only can greatly improve the work efficiency of the staff, but also can save the use of printing paper. In order to reduce the obstacles encountered in the transmission process of the printing paper as much as possible and make the printing paper more smoothly sent out from the waist-shaped hole 41, in the embodiment, the length and width of the waist-shaped hole 41 are greater than those of the printing port 31.

[0024] In the embodiment, one side edge position of the cover plate 4 and one side edge position of the shell 1 close to the opening part 1a are movably connected through the hinge 6, and the cover plate 4 can move along the side edge axis of the hinge 6 connection, so that the cover plate 4 can be easily covered on the opening part 1a or removed from the opening part 1a. The control panel 5 is provided with a buckle base 55 on the surface thereof towards the opening part 1a, and the cover plate 4 is provided with a buckle fastener 43 on the surface thereof close to the control panel 5. When the cover plate 4 covers the opening part 1a, that is, in the closed state, the buckle fastener 43 is inserted into the buckle base 55. Through such a closing mode, when the cover plate 4 covers the opening part 1a, the cover plate 4 is closed more firmly, which can ensure that when the steam sterilizer 100 is transported or the cover plate 4 is slightly collided, the cover plate 4 in the closed state will not be easily opened. Figure 2 The surface of the cover plate 4 away from the control panel 5 is also provided with a pressing part 42, and the staff can more labor-saving and conveniently open or close the cover plate 4 by slightly pushing the pressing part 42.

[0025] <Second embodiment>

[0026] The embodiment also provides a steam sterilizer 100 which sterilizes articles such as medical devices by steam sterilization.

[0027] In the embodiment, the control panel 5 in the housing 1 of the printing device 100c is arranged to face the surface of the opening 1a, and further comprises a lock core 51, a buzzer 52, a USB interface 54 and an emergency stop button 53.

[0028] In the embodiment, the control panel 5 in the housing 1 of the printing device 100c is arranged to face the surface of the opening 1a, and further comprises a lock core 51, a buzzer 52, a USB interface 54 and an emergency stop button 53. Figure 3 When the cover plate 4 covers the opening 1a, the emergency stop button 53 can be exposed from the emergency stop button hole 44, and even if the cover plate 4 is in a closed state, the worker can directly press the emergency stop button 53 through the emergency stop button hole 44 to shut down the steam sterilizer 100 when the steam sterilizer 100 has an emergency.

[0029] The above is only a preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
