Description

Technical Field

[0001] This utility model relates to a pulsed vacuum sterilizer with a built-in ultra-clean electric heating steam generator, belonging to the technical field of pulsed vacuum sterilizers. Background Technology

[0002] A pulsed vacuum sterilizer is a device specifically designed for steam sterilization of hollow items and utensils. Currently, the pulsed vacuum sterilizers in the sterilization supply centers of major hospitals in China use two types of steam sources: external and internal.

[0003] The built-in steam generator is fixed to the top of the sterilizer via a specific connection method. The steam generator uses a horizontal structure, with a steam generation chamber volume exceeding 30L. It has low steam generation efficiency and is classified as a pressure vessel, therefore requiring additional registration with the relevant authorities for use in hospitals. Furthermore, the lack of a dehumidification device makes it prone to wet packing issues during sterilization. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a pulsed vacuum sterilizer with a built-in ultra-clean electric heating steam generator. The steam generation chamber has a small volume and high steam generation efficiency. It is not a pressure vessel and does not require additional registration. It can fully filter out the moisture in the steam and avoid the problem of wet packs during the sterilization process.

[0005] The pulsed vacuum sterilizer with a built-in ultra-clean electric heating steam generator described in this utility model includes a housing, and a sterilizer and a steam generator are provided inside the housing. The steam generator is located on the side of the sterilizer and is connected to the interlayer of the sterilizer.

[0006] The steam generator is a vertical structure with several steam generating chambers arranged in an array inside. Each steam generating chamber is equipped with a heating pipe that heats the water entering the chamber to quickly generate steam. The upper part of the steam generating chamber is connected to a steam storage drum via a conduit. The steam storage drum is equipped with a steam-water separator to filter out moisture from the steam.

[0007] The technical solution of this utility model is to provide a pulsed vacuum sterilizer with an integrated ultra-clean electric heating steam generator. By dividing the overall steam generation chamber into multiple smaller steam generation chambers and installing heating tubes in each steam generation chamber, the volume and mass of water to be heated each time are reduced under the condition of the same heating tube power, thus significantly improving the steam generation efficiency. At the same time, the volume of the steam generation chamber is less than 23L, which does not belong to pressure vessel equipment and does not require additional registration. In addition, a steam-water separation device is installed in the steam storage drum to filter out the moisture in the steam, effectively avoiding the problem of wet drum.

[0008] Preferably, the bottom of the steam generating chamber is connected to the distribution cylinder, which distributes water evenly to each steam generating chamber.

[0009] Preferably, a temporary water tank is provided on one side of the diversion cylinder, the temporary water tank is connected to the inlet of the water pump, and the outlet of the water pump is connected to the diversion cylinder.

[0010] Preferably, the top of the steam storage drum is connected to the interlayer of the sterilizer via a sanitary pipe; the steam storage drum is also equipped with a return pipe, through which the water filtered by the steam-water separator is returned to the distribution cylinder.

[0011] Preferably, the steam-water separation device includes steam baffles and guide channels; there are multiple steam baffles, which are staggered one after the other, and steam outlet holes are evenly distributed on the steam baffles. Adjacent steam baffles are connected by guide channels; after steam is generated, it passes through the staggered steam baffles, where water is blocked, and then collects in the steam storage drum along the guide channels, and flows back to the distribution cylinder through the return pipe, thus achieving effective separation of steam and water.

[0012] Preferably, the diversion cylinder is also provided with a drain pipe, and a drain solenoid valve is installed on the drain pipe.

[0013] Preferably, a combined control system is also fixed on one side of the sterilizer; a control panel is installed on the casing.

[0014] The advantages of this utility model compared with the prior art are:

[0015] The pulsed vacuum sterilizer with a built-in ultra-clean electric heating steam generator described in this utility model has multiple smaller steam generation chambers, each equipped with a heating tube. This results in high steam generation efficiency. Furthermore, since the volume of each steam generation chamber is less than 23L, it is not classified as a pressure vessel and therefore does not require additional registration. Additionally, a steam-water separation device is installed to filter out moisture from the steam, effectively preventing the problem of wet packs during the sterilization process.

[0020] The present invention will be further described below with reference to specific embodiments.

[0021] However, the description of this utility model is only a structural or even functional description of the embodiments, and the scope of the present utility model is not limited by the embodiments described herein.

[0022] For example, multiple embodiments may have various modifications and forms, and it should be understood that the scope of this utility model includes equivalents that can realize the technical concept.

[0023] like Figures 1-3 As shown, this embodiment is achieved through the following technical solution: it includes a housing 1, and a sterilizer 10 and a steam generator are provided inside the housing 1. The steam generator is located on the side of the sterilizer 10 and is connected to the interlayer of the sterilizer 10.

[0024] The steam generator is a vertical structure. Several steam generating chambers 5 are arranged in an array inside the steam generator. Each steam generating chamber 5 is equipped with a heating pipe, which can heat the water entering the steam generating chamber 5 to quickly generate steam. The upper part of the steam generating chamber 5 is connected to the steam storage drum 4 through a conduit. The steam storage drum 4 is equipped with a steam-water separator to filter out the moisture in the steam.

[0025] In this embodiment, the bottom of the steam generating chamber 5 is connected to the distribution cylinder 6, which distributes water evenly to each steam generating chamber 5. A temporary water tank 8 is provided on one side of the distribution cylinder 6, connected to the inlet of the water pump 7, and the outlet of the water pump 7 is connected to the distribution cylinder 6. The top of the steam storage drum 4 is connected to the interlayer of the sterilizer 10 via a sanitary pipe 2; the steam storage drum 4 is also equipped with a return pipe 9, through which the water filtered by the steam-water separator is returned to the distribution cylinder 6.

[0026] The steam-water separation device includes steam baffles 41 and guide channels 42. Multiple steam baffles 41 are arranged in a staggered pattern, with steam outlets evenly distributed on each baffle. Adjacent baffles are connected by guide channels 42. After steam is generated, it passes through the staggered baffles 41, where moisture is blocked. The moisture then flows along the guide channels 42 into the steam storage drum 4 and back through the return pipe 9 to the distribution cylinder 6, achieving effective separation of steam and moisture. The distribution cylinder 6 is also equipped with a drain pipe 61, on which a drain solenoid valve is installed. A combined control system 3 is fixed to one side of the sterilizer 10; a control panel 11 is installed on the casing 1.

[0027] The working process of this utility model is as follows:

[0028] After the sterilizer 10 is turned on, the steam generator starts first. The heating tube inside the steam generating chamber 5 is electrically heated to quickly generate steam. The steam is collected in the steam storage tank 4 through the conduit. The moisture in the steam is blocked by the steam baffle 41 and then collected in the steam storage tank 4 through the guide groove 42. It is then returned to the distribution cylinder 6 through the return pipe 9. The steam with the moisture removed enters the jacket of the sterilizer 10 through the sanitary pipe 2 and begins to heat up, preparing for the sterilization process.

[0029] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
