a sterilizer

Abstract

The invention belongs to the technical field of disinfection equipment, and relates to a sterilizer. The sterilizer comprises a shell enclosed by an upper cover plate, a bottom plate, a front panel, a back panel and two vertical plates, wherein a heat component, a water tank component and a sterilization cylinder are arranged in the shell; the heat component comprises an arch part with an arch surface; the water tank component comprises an opening tank body; a connecting frame is connected outside the tank body in a sealed manner, and is clamped between the upper cover plate and the tank body; a first mounting hole is formed in the shell; a tank door is connected to the connecting frame in a hinged manner, and the opening of the tank body can run through the connecting frame and the first mounting hole; the tank door is arranged outside the shell, and a closed space is formed by the tank door, the connecting frame and the tank body when the tank door is covered. The invention also relates to a preparation method of the shell, which comprises the steps of preparing materials, molding by casting, thermally treating, plating silver, and performing ion bombardment to obtain the shell of the sterilizer. The sterilizer is reasonable in design, and convenient for assembling and disassembling the heat component; the shell has an antibacterial performance, and the corrosion resistance of the shell is not influenced.

Description

technical field [0001] The invention belongs to the technical field of disinfection equipment, and relates to a sterilizer. Background technique [0002] The sterilizer is designed by taking advantage of the fact that bacteria cannot survive under high temperature and high pressure, and is used to kill bacteria in items. The sterilizer is an ideal disinfection equipment. It is suitable for medical and health undertakings, scientific research undertakings, agriculture and other units. It can sterilize medical equipment, glassware, solution culture medium and other items. [0003] The heating device, water tank, and drain valve are all important components of the sterilizer. There are generally two ways to install the heating device in the prior art: one is to install the heating device outside the sterilizer cavity, and then heat the There is a waterway fixed outside the device, and the water in the waterway is heated by the heating device before being transported to the ste...

Problems solved by technology

[0003] The heating device, water tank, and drain valve are all important components of the sterilizer. There are generally two ways to install the heating device in the prior art: one is to install the heating device outside the sterilizer cavity, and then heat the There is a waterway fixed outside the device, and the water in the waterway is heated by the heating device before being transported to the sterilization cylinder. Such a heating device is inconvenient to install and disassemble. After long-term use, there will inevitably be scale in the waterway, and the waterway must be cleaned When the heating device must be removed at the same time, the unreasonable design makes the operation inconvenient; another installation method is to directly install the heating device at the bottom of the inner cavity of the sterilization cylinder, which makes the heating of the water in the sterilization cylinder more efficient. Direct and effective, but it is difficult to clean the sterilizer when cleaning the sterilization cylinder, the design is unreasonable, which affects the subsequent effective work of the sterilizer

[0004] In the prior art, the water tank is generally selected as a top-mounted type, which is installed on the upper cover of the sterilizer, and the top is completely open. When installing a top-mounted water tank, it is necessary to set a sealing gasket around the top of the water tank first, and then install the water tank. Together with the sealing gasket, it is snapped into the installation part of the upper cover plate, and finally the water tank is fixed on the sterilizer through screws and other parts. When performing such operations, the staff needs to constantly adjust the sealing gasket to make the top of the water tank and the sterilizer The sealing effect between the upper cover plates reaches the best state, which is time-consuming and labor-intensive, and the installation and disassembly are troublesome

In addition, because the water tank is an open structure, generally those skilled in the art will cover the water tank with a cover, and take the cover aside when water needs to be filled, and the staff often forget to cover the cover again after filling the water. , the design is unreasonable, and it is not convenient to use, which directly affects the normal operation of the sterilizer

In addition, the casings of sterilizers in the prior art are generally made of ordinary alloys, which have no sterilizing effect
