When cleaning the needle, the needle is placed on the mounting frame 11 through the discharge unit, and cleaning liquid is added to the cleaning cavity in the box body 1. The cover 2 closes the box body 1, and the lifting unit drives the discharge unit and the needle to move through the mounting plate 12, the second motor 10 and the mounting frame 11, so that the needle enters the cleaning liquid. The ultrasonic mechanism 9 emits high-frequency vibration waves into the cleaning chamber, forming a cavitation effect in the cleaning liquid, thereby causing impurities on the surface of the needle to be peeled off and fall off, thereby improving the cleaning effect of the needle. While cleaning, the second motor 10 drives the needle to rotate during the cleaning process through the mounting frame 11, and the flushing flow formed by the circulation unit can better clean the needle, facilitate the falling of impurities on the needle, and improve the cleaning effect. After cleaning is completed, the lifting unit drives the needle to move out of the cleaning liquid through the mounting plate 12, and the hot air unit blows the needle dry, and the UV lamp 7 sterilizes the needle.

[0029] like Figure 3 、 Figure 4 、 Figure 6 、 Figure 7The cam 306 is provided on the cam 304 so that the cam 306 can be adjusted by the user. The upper plate 303, the middle plate 304, the lower plate 305, the elastic component and the hollow box 310 can be used to prevent the needle from falling off during cleaning and to protect the needle.

[0030] like Figure 4 、 Figure 7 As shown, an elastic sleeve 307 is fixedly installed in the placement hole 306. The needle is placed in the elastic sleeve 307 when cleaning. The elastic sleeve 307 is used to facilitate positioning of different needles, reduce the deviation of the needle, and improve applicability. At the same time, the elastic sleeve 307 protects the needle and reduces collision damage to the needle.

[0031] like Figure 4 、 Figure 6 、 Figure 7As shown, the elastic component includes a damping rod 308, which is fixedly mounted on the corresponding sides of the upper plate 303 and the lower plate 305. The telescopic end of the damping rod 308 is connected to the hollow box 310. A spring 309 is sleeved on the damping rod 308. The hollow box 310 is supported by the spring 309 and the damping rod 308. During the lifting and lowering movement, the hollow box 310 can continue to fit on both ends of the needle, and the two ends of the needle are adaptively clamped and limited to prevent the needle from falling off the hollow box 310, thereby improving the safety of the needle during cleaning.

[0032] like Figure 2 、 Figure 3 、 Figure 5 As shown, the lifting unit includes a support frame 403, which is fixedly installed in the cleaning chamber in the box body 1, and a first motor 401 is fixedly installed on the support frame 403. A second screw rod 402 is rotatably installed on the support frame 403, and the second screw rod 402 is fixedly connected to the output shaft of the first motor 401. The second screw rod 402 is connected to the mounting plate 12 by threaded fitting. The second screw rod 402 is driven to rotate by the first motor 401, and the mounting plate 12 is driven to move up and down along the support frame 403 by the second screw rod 402. The turning needle can be placed in the cleaning chamber during cleaning, and can be driven to move out after cleaning is completed, thereby improving the convenience of the turning needle discharge. At the same time, the turning needle can be driven to move back and forth up and down in the cleaning liquid during the cleaning process, thereby better cleaning the turning needle and improving the cleaning effect.

[0033] like Figure 1 、 Figure 2 As shown, the circulation unit includes an infusion mechanism 601, a purification filter box 602, and a liquid outlet nozzle 603. The infusion mechanism 601 is fixedly arranged in the cleaning cavity in the box body 1, the purification filter box 602 is arranged on the side of the box body 1, and the liquid outlet nozzle 603 is arranged on the inner side of the box cover 2. The liquid outlet nozzle 603 is annular and is connected to the discharge end of the infusion mechanism 601 through the purification filter box 602. The infusion mechanism 601 and the purification filter box 602 both adopt existing technologies. A filter component is installed in the purification filter box 602. During operation, the cleaning liquid in the cleaning cavity is extracted through the infusion mechanism 601. The cleaning liquid is then transported to the purification filter cartridge 602, where the filter assembly in the purification filter cartridge 602 filters out impurities in the cleaning liquid, preventing the impurities in the cleaning liquid from adhering to the needle a second time and affecting the cleaning effect of the needle. The filtered cleaning liquid enters the liquid outlet nozzle 603 and is sprayed out through the liquid outlet nozzle 603, so that the cleaning liquid re-enters the cleaning chamber. The sprayed cleaning liquid rinses the surface of the needle, which can better remove impurities on the needle surface and make the impurities on the needle surface fall off more easily. Since the liquid outlet nozzle 603 is arranged in an annular shape, the rinsing range is increased, thereby ensuring the effect and efficiency of the needle cleaning.

[0034] like Figure 2As shown, the hot air unit includes a hot air delivery mechanism 501 and an air outlet pipe 502. The hot air delivery mechanism 501 is fixedly installed in the installation cavity in the box body 1, and the air outlet pipe 502 is fixedly installed on the inner side of the box cover 2. The air outlet pipe 502 is annular. The hot air delivery mechanism 501 is connected to the air outlet pipe 502. The hot air delivery mechanism 501 adopts the existing technology. The box cover 2 is equipped with a one-way exhaust mechanism for discharging the gas in the cleaning cavity. The hot air delivery mechanism 501 includes a disinfection and purification component, a heating component, and an air delivery component. The air entering the hot air delivery mechanism 501 is purified and disinfected by the disinfection and purification component. The air after purification and disinfection The air is heated by the heating component, and the heated air is transported to the air outlet pipe 502 through the air supply component and blown into the cleaning chamber through the air outlet pipe 502. After the needle is cleaned, the needle rises in the cleaning chamber, and the hot air flow ejected from the air outlet pipe 502 blows the needle dry. The hot air after disinfection and purification will not affect the needle. By blowing the needle dry, the cleaning liquid on the needle is prevented from dripping and polluting the environment when it is taken out, and the needle is prevented from breeding bacteria due to moisture, thereby improving the drying efficiency and hygiene of the needle. The excess gas is discharged through the one-way exhaust mechanism to avoid the pressure increase in the box body 1 and the danger.

[0035] like Figure 2 As shown, a drug concentration detection sensor 8 is fixedly installed in the cleaning chamber in the box body 1. During the cleaning process of the needle, the concentration of the cleaning liquid in the cleaning chamber is detected by the drug concentration detection sensor 8. When the cleaning liquid is insufficient, it can be added in time to ensure that there is enough cleaning liquid in the cleaning chamber to clean the needle, thereby ensuring the cleaning effect of the needle.

[0036] Working principle: Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 As shown, the first screw rod 302 is rotated by the knob, and the upper plate 303 is moved by the first screw rod 302 to adjust the distance between the upper plate 303 and the middle plate 304. The needle is placed in the placement hole 306 and protected by the elastic sleeve 307. The lower end of the needle is placed in the hollow box 310 on the lower plate 305. The first screw rod 302 is rotated in the opposite direction by the knob, and the upper plate 303 drives the hollow box 310 to move so that the hollow box 310 covers the upper end of the needle. The hollow box 310 is supported by the spring 309 and the damping rod 308, and the hollow box 310 limits the two ends of the needle.

[0037] like Figure 1 、 Figure 3 、 Figure 5As shown, the discharge unit for placing the turning needles is fixedly mounted on the mounting frame 11, cleaning liquid is added to the cleaning chamber in the box body 1, and the box body 1 is closed by the box cover 2. The second screw rod 402 is driven to rotate by the first motor 401, and the mounting plate 12 is driven to move by the second screw rod 402. The mounting plate 12 drives the turning needles into the cleaning liquid through the second motor 10 and the mounting frame 11. The ultrasonic mechanism 9 emits high-frequency vibration waves into the cleaning chamber, forming a cavitation effect in the cleaning liquid, thereby causing impurities on the surface of the turning needles to be peeled off.

[0038] like Figure 1-Figure 5 As shown, during the cleaning process, the second motor 10 drives the needle to rotate during cleaning through the mounting frame 11. At the same time, the infusion mechanism 601 extracts the cleaning liquid from the cleaning chamber and delivers it to the purification filter box 602. The impurities in the cleaning liquid are filtered by the filter assembly in the purification filter box 602. The filtered cleaning liquid enters the liquid outlet nozzle 603 and is sprayed out through the liquid outlet nozzle 603. The centrifugal force during rotation and the sprayed cleaning liquid rinse the surface of the needle, accelerating the removal of impurities on the needle surface. At the same time, the hollow box 310 is supported by the spring 309 and the damping rod 308, so that the hollow box 310 can continuously limit the needle.

[0039] like Figure 2 As shown, during the cleaning process, the concentration of the cleaning liquid in the cleaning chamber is detected by the agent concentration detection sensor 8. When the cleaning liquid is insufficient, it can be added in time to ensure that there is enough cleaning liquid in the cleaning chamber to clean the needle and ensure the cleaning effect of the needle;

[0040] like Figure 2 、 Figure 3 、 Figure 5 As shown, after cleaning is completed, the first motor 401 drives the second screw rod 402 to rotate in the opposite direction, and the second screw rod 402 drives the needle to move out of the cleaning liquid through the mounting plate 12. The heated air is delivered to the air outlet pipe 502 by the hot air delivery mechanism 501 and blown into the cleaning chamber through the air outlet pipe 502. The hot air flow ejected from the air outlet pipe 502 dries the needle, and at the same time, the UV lamp 7 sterilizes the needle.
