Referring to fig. 6 and 7, fig. 6 is a schematic structural view of the X-axis driving assembly 210, and fig. 7 is a schematic view of the fixing bracket 190 with the solution tank 230 mounted thereon. The X-axis driving assembly 210 includes a second linear motor 211 and a second screw rod 213, an output shaft of the second linear motor 211 is connected with one end of the second screw rod 213, a sliding block 215 is sleeved on the second screw rod 213, the sliding block 215 is in threaded connection with the second screw rod 213, the sliding block 215 can move left and right along the second screw rod 213, and the fixing bracket 190 is fixedly connected with the sliding block 215. The fixing bracket 190 is fixedly connected with the sliding block 215 through screws. When the second linear motor 211 rotates counterclockwise, the second screw rod 213 and the sliding block 215 cooperate to convert the rotation of the second linear motor 211 into a linear movement of the sliding block 215 from left to right along the second screw rod 213, and the fixing bracket 190 and the sliding block 215 move together because the fixing bracket 190 and the sliding block 215 are fixedly connected by screws, thereby realizing the displacement of the solution cartridge 230. A magnetic stripe 233 is provided at one end of the solution cartridge 230, and the magnetic stripe 233 records information about the solution cartridge 230, such as: production date, capsule quantity and capsule position. The card reader 171 is arranged on the supporting column 170, the card reader 171 is used for reading the recorded content of the magnetic stripe 233, after each time a new solution box 230 is replaced, the card reader 171 reads the information in the magnetic stripe 233, and after each time the liquid in the capsule is extracted, the card reader 171 records the position of the extracted capsule, so that all the liquid in all the capsules contained in the solution box 230 can be extracted. A control board 173 is provided at an end of the support column 170 remote from the card reader 171. A controller is arranged on the control board 173, the control board 173 is used for controlling the whole liquid injection device, and the limit sensor 113, the first linear motor 141, the second linear motor 211 and the card reader 171 are all electrically connected with the control board 173. In order to make the user more aware of how the card reader 171 records the extracted capsule position, the following is exemplified here: each solution cassette 230 typically contains 10 to 12 rows of capsules, each of which contains a chemical solution, such as hydrogen peroxide solution, for sterilization. If the liquid in the third row of capsules of the solution cartridge 230 is being extracted, and if the solution cartridge 230 moves to the right by two capsule position units (i.e. the solution in the fifth row of capsules is to be extracted), the control board 173 will perform the following operations according to the predetermined formula: the controller can determine that the liquid in the fourth row of capsules has not been extracted according to the distance moved by the solution box 230 this time, the control board 173 transmits a signal that the fourth row of capsules has not been extracted to the card reader 171, and the card reader 171 writes the content into the magnetic stripe 233 for recording, so that the next extraction is facilitated. That is, the magnetic strip 233 can record which capsules in the solution cartridge 230 have had their solutions extracted and which have not. And during the actual extraction process, the controller can control the solution cartridge 230 to move one capsule position unit at a time, thereby allowing the lower needle 153 to extract the solution in each capsule in turn.

The liquid injection device of the hydrogen peroxide low-temperature plasma sterilizer provided by the utility model has the working principle that:

the solution box 230 filled with the disinfection and sterilization liquid medicine capsules is inserted into the clamping groove 191, the control board 173 controls the second linear motor 211 to rotate, the fixing support 190 is driven to move rightwards, the magnetic strip 233 on the solution box 230 corresponds to the card reader 171, after the card reader 171 reads data in the magnetic strip 233, the second linear motor 211 rotates in the opposite direction, the fixing support 190 is driven to move leftwards, and when the solution box 230 moves to the leftmost position, the rightmost capsule of the solution box 230 faces the upper puncture needle 155 and the lower puncture needle 153. The control board 173 controls the first linear motor 141 to rotate to drive the liquid injection assembly 150 to approach the solution box 230. Meanwhile, the blocking block 131 gradually moves away from the conduit 157, so that the sterilizer and the liquid injection assembly 150 are communicated. When the limit sensor 113 far from the first linear motor 141 senses the limit block 161, the limit block 111 transmits a signal to the control board 173. At this time, the first linear motor 141 stops rotating, the upper needle 155 and the lower needle 153 both pierce the side wall of the capsule, the liquid in the capsule is extracted by the negative pressure in the sterilization chamber of the medical sterilizer, and the liquid is sent into the sterilization chamber of the sterilizer through the conduit 157, thereby completing the extraction of the liquid in the capsule.

After the liquid extraction is completed, the first linear motor 141 rotates in the opposite direction to drive the liquid injection assembly 150 to move away from the solution box 230. When the injection assembly 150 retreats away from the solution box 230, the blocking block 131 gradually approaches the contact conduit 157 and extrudes the contact conduit 157, until the position of the limiting block 161 is sensed by the limiting sensor 131 close to the first linear motor 141, the first linear motor 141 stops rotating, and the blocking block 131 is matched with the mounting groove 159 to completely extrude and block the conduit 157. At this time, if the next liquid pumping operation is required, the second linear motor 211 starts to rotate, the fixing bracket 190 moves rightwards by a distance of one capsule position unit, the second linear motor 211 stops rotating, and then the previous steps of pumping the liquid in the capsule are repeated. When all the capsules in the solution tank 230 are extracted, the second linear motor 211 rotates in the reverse direction, the solution tank 230 is withdrawn, and the worker needs to extract the solution tank 230 out of the card slot 191 and replace the solution tank 230 with a new one.

The above-mentioned embodiments only express the specific embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present application. It should be noted that, for those skilled in the art, without departing from the technical idea of the present application, several changes and modifications can be made, which are all within the protection scope of the present application.
