[0012] Compared with the prior art, the present invention has the following beneficial effects: This utility model provides a veterinary drug sterilizer with a uniform steam distribution structure. It employs a sterilization tank, a self-locking lid, a storage component, and a separation component. The storage component is installed into the sterilization tank using a snap-fit method. A circular funnel divides the storage tube into upper and lower parts, and the veterinary instruments to be sterilized are then separated by the separation component, preventing the instruments from being piled up. Protrusions one and two further separate the storage tube from the circular funnel, promoting steam diffusion. This solves the problem in existing veterinary drug sterilizers where some instruments cannot be sterilized due to being piled up in the sterilization tank. It achieves the beneficial effect of separating the instruments and increasing the contact area between the instruments and the steam. This utility model provides a veterinary drug sterilizer with a uniform steam distribution structure. It utilizes the cooperation between a sterilization tank and a uniform steam distribution mechanism. By controlling a steam jet pump, high-pressure steam kinetic energy is used to achieve gas suction and pressurization. When the high-pressure steam passes through the nozzle, it generates a high-speed airflow, creating a low-pressure zone at the nozzle outlet. Low-pressure steam is drawn into this zone, and air is repeatedly extracted and injected with steam, reducing the air residue rate and ensuring that steam penetrates the internal pores of the item, achieving sterilization without dead angles. This solves the problem that during the sterilization process, a large air content in the sterilization tank prevents steam from penetrating the internal pores of the item, thus achieving the beneficial effect of promoting uniform steam distribution.

[0021] The working principle of this veterinary drug sterilizer with a uniform steam distribution structure will be explained in detail below.
[0022] like Figure 1-5 As shown, when using this veterinary sterilizer to sterilize veterinary instruments, firstly, depending on the size of the instruments, the instruments to be sterilized can be separated by assembling and disassembling the partition 72 along the slot 710. Then, the circular drip tray 63 is placed on the annular support 62 to achieve multi-layer sterilization. After placement, the placement drip cylinder 61 is placed into the first chamber 101. The locking block 64 is rotated and engaged into the concave fixing plate 103 for positioning. The self-locking lid 2 is then closed. Sterilization water is then injected into the second chamber 102 through the injection pipe 9. The bottom heater 3 is activated via the control panel 5 to heat and boil the sterilization water in the second chamber 102, generating steam. Then, the steam is... Start the steam jet pump 81. The steam jet pump 81 uses high-pressure steam to expand thermally, converting pressure energy into kinetic energy to form a supersonic steam flow, creating a local low-pressure zone. This causes the mixing pipe 82 to draw in surrounding gas. The drawn-in gas and high-speed steam are fully mixed in the mixing pipe 82, and energy is transferred through momentum exchange, allowing the steam to be delivered into the first chamber 101. Air is discharged along the exhaust pipe 84. By repeatedly evacuating air and injecting steam, the air residue rate is reduced, ensuring that the steam penetrates the gaps between the veterinary instruments and achieves sterilization without dead angles. After sterilization is completed, open the safety valve 12 and the solenoid valve 13 to discharge the gas in the first chamber 101. Then open the valve 11 to discharge the remaining sterilization water.
