The fourth valve body 1111 is used to control the on-off of the second waste pipe 111, so that the steam filled in the second heating plate 11 and the water generated by the liquefaction of the steam can be discharged.

[0045] Based on the above, the steam source 5 in this embodiment also has the function of supplying steam to the second heating plate 11 to preliminarily heat the water in the water tank 1. In other words, in this embodiment, there is no need to set up an additional structure specifically for heating the second heating plate 11, thereby further simplifying the structure of the instrument cleaning device.

[0046] It should be noted that the steam source 5 is connected to the cleaning chamber 2 through the first steam pipeline 51, and is connected to the first heating plate 21 and the second heating plate 11 through the second steam pipeline 52 and the third steam pipeline 53 respectively. The first steam pipeline 51, the second steam pipeline 52 and the third steam pipeline 53 are all provided with a fifth valve body 511, so as to control the opening and closing of the first steam pipeline 51, the second steam pipeline 52 and the third steam pipeline 53 respectively.

[0047] Based on the contents mentioned above, the instrument cleaning device in this embodiment also includes a water source 6, which is connected to the water tank 1 and the cleaning chamber 2. Specifically, the water source 6 is connected to the water tank 1 through a first water injection pipe 61, so that water can be replenished in the water tank 1 after the water tank 1 supplies water to the cleaning chamber 2. The water source 6 is also connected to the cleaning chamber 2 through a second water injection pipe 62. During the cleaning stage, the liquid in the cleaning chamber 2 needs to be at a suitable temperature to ensure that the medical instruments are fully cleaned, and during the rinsing stage, the liquid in the cleaning chamber 2 needs to be at a suitable temperature to ensure that the medical instruments are fully rinsed. Therefore, when the temperature of the liquid in the cleaning chamber 2 is heated to too high, the water source 6 can also directly inject water into the cleaning chamber 2 to cool down the liquid in the cleaning chamber 2.

[0048] Wherein, the first water injection pipeline 61 and the second water injection pipeline 62 are both provided with a sixth valve body 611 , so as to control the on-off of the first water injection pipeline 61 and the second water injection pipeline 62 .

[0049] It is understandable that in this embodiment, the water tank 1 and the cleaning chamber 2 are both provided with a temperature sensor 13, so that the temperature of the liquid in the water tank 1 and the cleaning chamber 2 can be detected. In this embodiment, a PT100 sensor is used as the temperature sensor 13. Of course, in other optional embodiments, other types of temperature sensors may also be used, and this embodiment does not specifically limit this.

[0050] Furthermore, the instrument cleaning device also includes a circulation pipeline 81 and a spray head 82. The spray head 82 is arranged in the cleaning chamber 2 and is located at the top of the internal cavity of the cleaning chamber 2. One end of the circulation pipeline 81 is connected to the bottom of the cleaning chamber 2, and the other end of the circulation pipeline 81 is connected to the spray head 82. The liquid mixed with the detergent and water can circulate between the bottom and the top of the cleaning chamber 2 along the circulation pipeline 81, and the liquid flowing to the top of the cleaning chamber 2 can be sprayed into the cleaning chamber 2 through the spray head 82.

[0053] Furthermore, the instrument cleaning device in the present embodiment also includes a vacuum pump 7, which is configured to evacuate the internal cavity of the cleaning chamber 2, thereby reducing the air pressure in the cleaning chamber 2. Specifically, before the rinsing stage and the cleaning stage, the vacuum pump 7 can evacuate the cleaning chamber 2 to reduce the air pressure in the cleaning chamber 2, thereby reducing the boiling point of the water in the cleaning chamber 2, and thus allowing the liquid in the cleaning chamber 2 to boil quickly during the rinsing stage and the cleaning stage, thereby shortening the time for heating the liquid in the cleaning chamber 2 to boiling while ensuring the cleaning and rinsing effects, thereby further improving the working efficiency of the instrument cleaning device.

[0054] It should be noted that the vacuum pump 7 in this embodiment is a water ring vacuum pump, and therefore the vacuum pump 7 is also connected to the water source 6 and the drainage pipeline 41 .

[0055] In addition, the instrument cleaning device in this embodiment also includes a return air pipeline 43, the two ends of which are respectively connected to the cleaning chamber 2 and the outside world, so that the air pressure in the cleaning chamber 2 is restored to atmospheric pressure after cleaning, and the air pressure in the cleaning chamber 2 is restored to atmospheric pressure after rinsing.

[0056] Specifically, a ninth valve body 431 is provided on the air return line 43 , so as to control the on-off of the air return line 43 .

[0057] After the disinfection is completed, the medical device needs to be dried.

The downstream end of the third passage 931 is connected to the bottom of the cleaning cabin 2, the downstream end of the fourth passage 932 is connected to the middle of the cleaning cabin 2, and the downstream end of the fifth passage 933 is connected to the top of the cleaning cabin 2. The heated air can be sent to the bottom, middle and top of the cleaning cabin 2, thereby fully drying the medical device.

[0058] It can be understood that in this embodiment, the upstream ends of the fourth passage 932 and the fifth passage 933 are both connected to the downstream end of the sixth passage 934, and the upstream end of the sixth passage 934 is connected to the heater 92. The third passage 931 and the sixth passage 934 are both provided with a tenth valve body 9311, so as to control the opening and closing of the third passage 931 and the sixth passage 934.

[0059] It is worth noting that in the present embodiment, during the drying stage, the vacuum pump 7 also evacuates the cleaning chamber 2 to reduce the air pressure in the cleaning chamber 2, thereby reducing the boiling point of the water in the cleaning chamber 2, and further facilitating the vaporization of liquid water attached to the surface of the medical device to further dry the medical device. The vaporized water can be sucked away by the vacuum pump 7 together with the air in the cleaning chamber 2.

[0060] Furthermore, an air filter 912 is provided on the first ventilation pipeline 91. The air filter 912 is located on the upstream side of the fan 911 to filter the air sent to the heater 92, so as to prevent the air sent into the cleaning cabin 2 from being accompanied by impurities such as dust, thereby avoiding contamination of medical equipment.
