Description

Technical Field

[0001] The utility model relates to the technical field of disinfection cabinets, in particular to a steam disinfection cabinet. Background Art

[0002] Steam sterilization refers to a method of using high-temperature steam to kill bacteria or microorganisms. Since pure steam has strong penetrability, proteins and protoplasm colloids are easily denatured and coagulated under hot and humid conditions. Steam enters the cells and condenses into water, which can release potential heat and increase the temperature. Therefore, steam sterilization has a stronger bactericidal function.

[0003] For example, a common air pressure high temperature steam sterilizer disclosed in the utility model patent with Chinese patent number CN201520139383.0 includes a cabinet body, an inner tank and a steam generating assembly are respectively arranged in the cabinet body, a heating element is arranged in the inner cavity of the inner tank, an air inlet is arranged at a position corresponding to the heating element on the inner tank, an air outlet of the steam generating assembly is connected to the air inlet of the inner tank through a steam delivery pipe, and a fan is also arranged on the cabinet body, the air inlet of the fan is connected to the inner cavity of the inner tank, and the air outlet of the fan is connected to the atmosphere. The steam generated by the above-mentioned steam generating assembly enters the inner cavity of the inner tank through the steam delivery pipe, and can disinfect the items in the inner tank. However, the steam generating assembly occupies a large space, resulting in a low effective utilization rate of the inner tank, and the steam in the steam generating assembly is input into the inner tank by an external transfer method, which is prone to problems such as insufficient steam delivery and residual steam in the steam delivery pipe. The steam cannot be discharged in the steam delivery pipe for a long time, which will cause the steam delivery pipe to mold, rot, and clog, affecting the service life and disinfection quality of the disinfection cabinet. In addition, the steam will experience temperature decay during the delivery process, resulting in a waste of resources.

[0004] Therefore, further improvement is necessary. Utility Model Content

[0029] The utility model is further described below in conjunction with the accompanying drawings and embodiments. Embodiment 1

[0030] See also Figure 1-Figure 6 The steam sterilizer comprises an outer shell 1, a sterilizing liner 2 is arranged in the outer shell 1, a water tank 3 and a fluid controller 4 are arranged outside the sterilizing liner 2, a heating tube 5 and a water tray 6 are arranged inside, the fluid controller 4 is connected with the water tank 3 and the water tray 6 through pipelines, and an ultrasonic mister 7 is arranged on the water tray 6.

[0031] In this embodiment, a pipeline is used to connect the fluid controller 4, the water tank 3, and the water tray 6, so that the water in the water tank 3 can be directly pumped into the water tray 6 through the fluid controller 4. In addition, an ultrasonic mist generator 7 is used to ultrasonically atomize the water in the water tank 3 into steam, thereby achieving the effect of directly forming steam in the disinfection liner 2, avoiding the problems of mildew, decay, blockage, etc. caused by the need to transport steam from the outside to the disinfection liner 2 in the prior art. Moreover, the heating tube 5 can perform secondary heating on the steam, and can complete the drying of the steam and the comprehensive disinfection of the objects in the disinfection liner 2 in a relatively short time, which not only ensures that the objects in the disinfection liner 2 are dry, but also effectively improves the disinfection effect and efficiency, and reduces the use cost.

[0032] A control circuit board 9 is also provided on the outside of the disinfection liner 2, and the control circuit board 9 is electrically connected to the fluid controller 4, the heating tube 5, and the ultrasonic mist generator 7 respectively.

[0033] The fluid controller 4 pumps the water in the water tank 3 into the water tray 6 through the control of the control circuit board 9, the heating tube 5 heats the inside of the disinfection liner 2 through the control of the control circuit board 9, and the ultrasonic mist generator 7 atomizes the water in the water tray 6 through the control of the control circuit board 9.

[0034] An opening is provided at the bottom of the disinfection liner 2 , a water tray 6 is located outside the disinfection liner 2 and fixedly arranged on the opening, a surface of the water tray 6 is flush with the bottom surface of the disinfection liner 2 , and an ultrasonic mist generator 7 is arranged at the bottom or side of the water tray 6 .

[0035] In this embodiment, the ultrasonic mist generator 7 is an ultrasonic atomizing sheet, which is fixed against the bottom of the water tray 6 and is electrically connected to the control circuit board 9. The fluid controller 4 pumps the water in the water tank 3 into the water tray 6 under the control of the control circuit board 9. When the ultrasonic mist generator 7 stores water in the water tray 6, it generates ultrasonic waves under the control of the control circuit board 9 and atomizes the water in the water tray 6 into steam.

[0036] That is, when working, the water pumping amount of the fluid controller 4 can be controlled by the control circuit board 9. Under the control of the control circuit board 9, the fluid controller 4 first extracts a certain amount of water in the water tank 3 and transports it to the water tray 6. Then the control circuit board 9 controls the ultrasonic fogger 7 to work. The ultrasonic fogger 7 generates ultrasonic waves when working, and atomizes the water in the water tray 6 into steam, so that steam is generated inside the disinfection liner 2. After the disinfection liner 2 is filled with steam, the fluid controller 4 and the ultrasonic fogger 7 stop working, and the heating tube 5 starts working, which not only heats and disinfects the objects in the disinfection liner 2, but also heats the steam at the same time to make the steam generate a higher temperature, thereby comprehensively disinfecting the objects in the disinfection liner 2 in a shorter time, and at the same time can also achieve rapid drying of the steam.

[0037] The pipeline includes an inlet pipe 10 and an outlet pipe 11. The fluid controller 4 is a water pump or a solenoid valve, whose inlet end is connected to the water tank 3 through the inlet pipe 10, and whose outlet end is connected to the side or bottom of the water tray 6 through the outlet pipe 11.

[0038] The water in the water tank 3 enters the water tray 6 through the water inlet pipe 10 , the fluid controller 4 , and the water outlet pipe 11 in sequence.

[0039] A fixing plate 12 is provided on the outer shell 1 or the sterilizing liner 2 . The fixing plate 12 is located at the top, back, side or bottom of the sterilizing liner 2 . The fluid controller 4 and the control circuit board 9 are fixedly provided on the fixing plate 12 , respectively.

The fixing plate 12 is fixedly provided on the outer frame 13 and is located on the top of the sterilization liner 2 .

[0041] A bracket 14 is provided on the outer shell 1, the disinfection liner 2 or the outer frame 13, and the water tank 3 is detachably mounted on the bracket 14, or the water tank 3 is fixedly mounted on the bracket 14 and a water supply pipe connected to the water supply end is provided thereon.

[0042] The water tank 3 is removable and can be filled with water or connected to a water supply end to directly add water for water replenishment, which is convenient for users to use.

[0043] In this embodiment, the fixed plate 12 is located at the top of the disinfection liner 2 and is fixedly connected to the outer frame 13. The fluid controller 4 and the control circuit board 9 are fixedly set on the fixed plate 12. The bracket 14 is located on the front side of the fixed plate 12 and is fixedly set on the top of the disinfection liner 2. The water tank 3 is disassembled and assembled on the top of the disinfection liner 2 through the bracket 14, which can improve space utilization.

[0044] Since the water tank 3 is arranged at the top and the water tray 6 is arranged at the bottom, and the water outlet pipe 11 extends from top to bottom, the water in the water tank 3 can smoothly flow into the water tray 6 without backflow or blockage problems.

[0045] The water tank 3 of this embodiment is disassembled and assembled to achieve water replenishment.

[0046] Specifically, a front frame 15 is provided on the front side of the outer frame 13, a fixed panel 16 is provided on the front frame 15, a fixed panel disassembly port is provided on the fixed panel 16, the bracket 14 is located at the rear side of the fixed panel disassembly port, and the water tank 3 is disassembled and assembled on the bracket 14 through the fixed panel disassembly port, thereby allowing the user to directly disassemble and assemble the water tank 3 at the fixed panel disassembly port, which is convenient to use.

[0047] In addition, the front frame 15 is provided with a front frame disassembly opening 17, the bracket 14 is located at the rear side of the front frame disassembly opening 17, the water tank 3 is disassembled and assembled on the bracket 14 through the front frame disassembly opening 17, and a pull-out basket is slidably provided on the disinfection liner 2, and the pull-out basket covers or opens the front frame disassembly opening 17 through its pull-out basket panel 18 when sliding, thereby allowing the user to disassemble and assemble the water tank 3 through the front frame disassembly opening 17 after opening the pull-out basket, and when the pull-out basket is closed, the pull-out basket panel 18 can cover the front frame disassembly opening 17, which not only avoids the water tank 3 from being exposed, but also improves the overall appearance of the product.

[0048] In this embodiment, a slide groove is provided on the bracket 14, and the water tank 3 is slidably disassembled on the slide groove of the bracket 14 through the fixed panel disassembly port or the front frame disassembly port 17. In addition, a limiting member is also provided on the bracket 14, and the water tank 3 is limited by the limiting member during assembly. Embodiment 2

[0049] See also Figure 7-10 The present steam sterilizer is different from the first embodiment in that a heater 8 is provided on the water tray 6 .

[0050] The heater 8 of this embodiment preheats the water tank 3 and then directly evaporates the water into steam, thereby achieving the effect of directly forming steam in the disinfection liner 2, avoiding the problems of mildew, decay, blockage, etc. caused by the need to transport steam from the outside to the disinfection liner 2 in the prior art. Moreover, since the steam is directly generated in the disinfection liner 2, the temperature of the steam will not have the problem of transmission attenuation. The high-temperature steam combined with the secondary heating of the heating tube 5 can complete the drying of the steam and the comprehensive disinfection of the objects in the disinfection liner 2 in a relatively short time, which not only ensures that the objects in the disinfection liner 2 are dry, but also effectively improves the disinfection effect and efficiency, and reduces the cost of use.

[0051] The heater 8 is arranged at the bottom or side of the water tray 6 .

[0052] The control circuit board 9 is electrically connected to the fluid controller 4 , the heating tube 5 , and the heater 8 respectively.

[0053] Specifically, the heater 8 is a heating disk, which is wound around the bottom of the water tray 6 and is electrically connected to the control circuit board 9. The heater 8 generates heat and heats the water tray 6 under the control of the control circuit board 9. The fluid controller 4 pumps the water in the water tank 3 into the heated water tray 6 under the control of the control circuit board 9. The water evaporates into steam when it meets the heated water tray 6.

[0054] That is, when working, the control circuit board 9 first controls the heater 8 to work and heat the water tray 6. After the water tray 6 is heated for a period of time, the fluid controller 4 extracts a certain amount of water in the water tank 3 and transports it to the heated water tray 6 through the control of the control circuit board 9. When the water enters the heated water tray 6, it will immediately evaporate into steam, so that high-temperature steam is generated inside the disinfection liner 2. After the disinfection liner 2 is filled with high-temperature steam, the fluid controller 4 and the heater 8 stop working, and the heating tube 5 starts working, which not only heats and disinfects the objects in the disinfection liner 2, but also reheats the high-temperature steam to make the high-temperature steam generate a higher temperature, thereby comprehensively disinfecting the objects in the disinfection liner 2 in a shorter time, and at the same time can also achieve rapid drying of the steam.
