Moreover, the air cylinder can also be started, and the output end of the air cylinder drives the block to move left along the guide rail, thereby driving the front group of guide blocks leftward. The guide blocks slide along the guide grooves while being driven leftward, so that the upper and lower nozzles move upward while moving leftward. The farther the outer nozzles move upward, the more the distance they move upward.

When the nozzles are gradually turned over, the turned-over nozzles gradually face the vertically arranged and inclinedly placed filter head bodies, so that the high-temperature steam is directly sprayed into the filter head body, thereby further increasing the sterilization effect and efficiency of the filter head body. After the steam enters the filter head body, water droplets are formed on the inner wall of the filter head body. The water droplets in the upper filter head body flow downward along the inner wall of the filter head body, while the water droplets in the lower filter head body gather to form a water mass. When the lower filter head body rotates to the upper position, the water mass flows downward along the filter head body, thereby flushing the impurities in the filter head, and achieving the effect of cleaning the inside of the filter head body.

Figures 1-3 ​As shown, a sterilization device for filter cartridge pipette tips includes a sterilization box 10, a sealed door 11 is installed on the front of the sterilization box 10, and a pipette tip placement mechanism 40 is provided on the left side of the interior of the sterilization box 10; a steam sterilization mechanism 20 is provided on the right side of the exterior of the sterilization box 10, and the steam sterilization mechanism 20 includes a connecting box 201 fixedly connected to the right side of the sterilization box 10, a steam generator 202 is fixedly installed on the inner bottom side of the connecting box 201, and the output end of the steam generator 202 is fixedly connected to an air outlet pipe 203, and the other end of the air outlet pipe 203 passes through the right surface of the sterilization box 10 and is located inside the sterilization box 10.

[0029] Specifically, the steam generator 202 consists of a heater and a heated water tank. A water injection pipe 206 is fixedly connected to the right side of the water tank and extends through the interior of the connection box 201. An air inlet pipe 204 is fixedly connected to the right side of the sterilization box 10. The other end of the air inlet pipe 204 is fixedly connected to the water tank. A condenser 205 is fixedly mounted on the air inlet pipe 204. Check valves 207 are installed on the air outlet pipe 203, the air inlet pipe 204, and the water injection pipe 206. During operation, the air outlet pipe 203 only allows steam rising from the water tank to be discharged through the air outlet pipe 203, while the water injection pipe 206 only allows water to be injected into the water tank from the outside. The air inlet pipe 204 only allows excess steam from the sterilization box 10 to enter, where it is condensed and returned to the water tank.

[0030] Furthermore, a controller 12 is fixedly installed on the front of the connection box 201, and the controller 12 is electrically connected to the steam generator 202; a humidity detector 14 is fixedly installed on the left end of the inner top side of the sterilization box 10, and a temperature detector 13 is fixedly installed on the right end of the inner top side of the sterilization box 10, and the temperature detector 13 and the humidity detector 14 are respectively electrically connected to the controller 12.

The controller 12 is operated to connect an external power source to activate the steam generator 202. The steam generator 202 generates high-temperature steam, which rises and is discharged into the sterilization chamber 10 through the exhaust pipe 203. Once the sterilization chamber 10 is filled with steam, the penetrating high-temperature steam effectively sterilizes the filter tip bodies 405, which can carry bacteria and other microorganisms. During this process, the temperature and humidity inside the sterilization chamber 10 are fed back by the temperature detector 13 and the humidity detector 14. The temperature detector 13 accurately measures the temperature to ensure that the temperature inside the sterilization chamber 10 reaches the predetermined sterilization temperature, effectively killing microorganisms and improving the sterilization effect. During steam sterilization, an appropriate humidity level ensures that the steam fully penetrates the product interior, achieving a better sterilization effect. The humidity detector 14 ensures that the humidity is controlled within an appropriate range.

[0034] In use, when steam is concentratedly sprayed to the surface of the support disc 403, part of the steam enters the inside of the bypass grooves 407 through the middle through groove 406 and then enters the inside of each independent inclined slot 404 to sterilize the outside of the independent filter core suction head body 405; when the nozzle 303 gradually turns over, the turned-over nozzle 303 gradually faces the vertically arranged and inclinedly placed filter core suction head body 405, so that high-temperature steam is directly sprayed into the inside of the filter core suction head body 405, further increasing the sterilization effect and efficiency of the filter core suction head body 405; after the steam enters the inside of the filter core suction head body 405, water droplets are formed on the inner wall of the filter core suction head body 405, the water droplets in the inside of the filter core suction head body 405 located at the upper position flow down along the inner wall of the filter core suction head body 405, and the water droplets in the inside of the filter core suction head body 405 located at the lower position flow to the deep position and gather into a water group at the deepest position of the filter core suction head 405; when the filter core suction head body 405 located at the lower position turns to the upper position, the water group flows down along the inner wall of the filter core suction head body 405 and washes away the impurities in the filter core, achieving the effect of cleaning the inside of the filter core suction head body 405. Meanwhile, the controller 12 starts the motor 401 through the external power supply, the output end of the motor 401 drives the tray 402 and the support disc 403 to rotate, so that the filter core suction head bodies 405 at different positions can all turn over to the vertical position and face the nozzle 303, so that all the filter core suction head bodies 405 can be effectively sterilized. Meanwhile, after sterilization, the tray 402 and the support disc 403 can be separated by opening the clasp, so that the support disc 403 is conveniently taken out.

[0036] In use, the pull rod 411 is pulled upward, the pull rod 411 drives the pressing block 410 to move upward and make the supporting spring 412, then the filter head body 405 is inserted into the inside of the inclined slot 404, and the pull rod 411 is released, so that the supporting spring 412 rebounds to drive the pressing block 410 to abut against the surface of the filter head body 405, thereby achieving the effect of positioning the filter head body 405.

[0037] Reference Figures 1-6 The inside right side of the sterilization box 10 is provided with an adjusting mechanism 30, the adjusting mechanism 30 comprises a connecting box 301 fixedly connected with the right side of the sterilization box 10, the right side of the connecting box 301 is fixedly communicated with the air outlet pipe 203, the left side of the connecting box 301 is fixedly connected with a group of vertically arranged folding hoses 302, and the left side of the folding hose 302 is fixedly connected with adjustable spray heads 303.

[0038] Preferably, the folding hose 302 is provided with a flow valve 304, and the flow valve 304 is electrically connected with the controller 12 respectively. The flow valve 304 is controlled by the controller 12 to accurately adjust the steam discharge flow of each spray head 303, so as to avoid waste of steam and effectively reduce energy consumption.

[0039] Specific, the inside right side of the sterilization box 10 is fixedly connected with a support plate 305, the top left side of the support plate 305 is fixedly connected with a fixed frame 306, the inside of the fixed frame 306 is hollow, the left and right sides are open, a group of guide grooves 307 are formed in the front and back sides of the fixed frame 306, wherein the guide groove 307 at the middle position is horizontal, and the guide grooves 307 at the upper and lower sides thereof are designed to gradually incline to the middle from left to right, and the inclination angle of the guide grooves 307 at the outer sides is larger; the outer side of the spray head 303 is fixedly connected with a connecting block 308, the front and back sides of the connecting block 308 are fixedly connected with connecting rods 309 respectively, the outer sides of the connecting rods 309 are rotatably connected with guide blocks 316, and the connecting rod 309 at the middle position is fixedly connected with the guide block 316, the guide block 316 is slidably connected with the corresponding guide groove 307; the front surface of the fixed frame 306 is fixedly connected with guide rails 312 on the upper and lower sides respectively, a pair of guide rails 312 are slidably connected with a driving block 315 on the inner sides, a vertical groove is formed in the rear side of the driving block 315, and the vertical groove is slidably connected with a group of connecting rods 309 on the front side; a gas cylinder 310 is arranged on the right side of the driving block 315, the base of the gas cylinder 310 is fixedly connected with the inner wall of the sterilization box 10, and the output end of the gas cylinder 310 is fixedly connected with the driving block 315.

[0040] In the initial state, the guide block 316 is located at the rightmost side of the guide groove 307, so that the interval between a group of nozzles 303 is small. In this case, the steam generator 202 is turned on, and the high-temperature steam generated by the steam generator 202 enters the inside of the connecting box 301 through the gas outlet pipe 203, and then uniformly enters each folded hose 302 and is sprayed out through a group of nozzles 303. Since the nozzles 303 have a small interval, the sprayed steam is concentratedly discharged to the position of the suction head placing mechanism 40, so that the temperature of the position of the suction head placing mechanism 40 rapidly rises, thereby accelerating the death speed of microorganisms and improving the sterilization efficiency. Moreover, the air cylinder 310 can be started, and the output end of the air cylinder 310 drives the block 315 to move leftward along the guide rail 312, thereby driving the guide block 316 on the front side leftward. While the guide block 316 is driven leftward, the guide block 316 slides along the inside of the guide groove 307, so that the nozzles 303 on the upper and lower sides move upward while moving leftward, and the nozzles 303 on the outer sides move upward by a greater distance, so that a group of nozzles 303 are bifurcated outward with the center as a bifurcation point, thereby increasing the interval between a group of nozzles 303. In this case, the steam generator 202 is turned on, so that when the nozzles 303 spray steam, the steam is discharged at different positions. The dispersed discharge of steam can make the steam form a more extensive distribution in the sterilization space, thereby enhancing the penetration of the steam, and the dispersed discharge helps the steam to better penetrate into every corner and gap of the sterilized objects, thereby improving the thoroughness of sterilization. Moreover, the dispersed discharge of steam can make the temperature and humidity in the sterilization space more uniform, and the uniform temperature and humidity distribution helps to achieve more uniform sterilization effect, thereby avoiding the occurrence of dead angles or over-sterilization during the sterilization process.

[0041] Further, the outer side of a group of guide grooves 307 is fixedly connected with an inclined tooth plate 313 (except for the middle guide groove 307), the inclination degree of the inclined tooth plate 313 is matched with the inclination degree of the corresponding guide groove 307, so that the length of the inclined tooth plate 313 on the outer side is longer; the outer side of the connecting rod 309 corresponding to the position of the inclined tooth plate 313 is fixedly connected with a gear 314, and the gear 314 is engaged with the corresponding inclined tooth plate 313.

[0042] In the process of driving a group of nozzles 303 to diverge from the output end of the air cylinder 310, the nozzles 303 drive the rear connecting rod 309 to move in the same direction, drive the corresponding gear 314 to transmit along the surface of the inclined tooth plate 313, and make the connecting rod 309 and the nozzles 303 turn outward; while the nozzles 303 spray steam, the nozzles 303 turn outward, so that the sprayed steam forms a fan shape. The fan-shaped gas injection can cover a larger area, so that more filter suction heads can be sterilized in one gas injection process; and by positioning the output end of the air cylinder 310 at different positions, the nozzles 303 are positioned at different turning angles, allowing gas to be injected from multiple angles and positions, ensuring that each filter suction head can be uniformly and sufficiently sterilized, especially those hard-to-reach corners and gaps. Fan-shaped gas injection helps to form strong airflow disturbance, thereby more effectively stripping and removing microorganisms attached to the surface of the filter suction head.

[0043] The working principle of the present application is: in the initial state, the guide block 316 is located at the rightmost side of the guide groove 307, so that the interval between a group of nozzles 303 is small. In this case, the steam generator 202 is started, high-temperature steam generated by the steam generator 202 enters the inside of the connecting box 301 through the gas outlet pipe 203, then the steam uniformly enters each folded hose 302 and is sprayed out through a group of nozzles 303. Because the interval between the nozzles 303 is small, the sprayed steam is concentratedly discharged to the position of the suction head placing mechanism 40, so that the temperature of the position of the suction head placing mechanism 40 rapidly rises, thereby accelerating the death speed of microorganisms and improving the sterilization efficiency. Moreover, the air cylinder 310 can also be started, the output end of the air cylinder 310 drives the block 315 to move leftward along the guide rail 312, drives the front group of guide blocks 316 leftward, and drives the guide blocks 316 to slide along the inside of the guide groove 307 while moving leftward, so that the nozzles 303 on the upper and lower sides move upward while moving leftward, and the nozzles 303 on the outer side move upward by a greater distance, so that a group of nozzles 303 diverge outward with the center as the diverging point, increasing the interval between a group of nozzles 303. In this case, the steam generator 202 is started, so that when the nozzles 303 spray steam, the steam is discharged at different positions. The dispersed discharge of steam can form a more extensive distribution in the sterilization space, thereby enhancing the penetration of steam, and the dispersed discharge of steam helps the steam to better penetrate into every corner and gap of the sterilized object, improving the thoroughness of sterilization. Moreover, the dispersed discharge of steam can make the temperature and humidity in the sterilization space more uniform, and the uniform temperature and humidity distribution helps to achieve more uniform sterilization effect, avoiding the occurrence of dead angles or over-sterilization during the sterilization process.
