The peripheral wall of the medicine feeding tube 28 is provided with a plurality of transmission grooves 283, the transmission grooves 283 are linear grooves and extend along the axial direction of the medicine feeding tube 28, and the plurality of transmission grooves 283 are uniformly distributed along the peripheral direction of the medicine feeding tube 28. The upper end peripheral wall of the medicine feeding tube 28 is provided with a ring groove 281.
The drive assembly includes a power spring 25, a lower pressure plate 24, a drive ring 26 and a drive sleeve 27. The lower pressure plate 24 is disc-shaped, the lower pressure plate 24 is horizontally arranged and is axially and downwardly slidably arranged in the mounting shell 22 along the mounting shell 22, the lower pressure plate 24 is positioned above the upper medicine tube 28, the peripheral wall is in contact with the inner wall of the mounting shell 22, and the lower pressure plate is configured to be downwardly slidable only along the axial direction of the mounting shell 22. The transmission sleeve 27 is rotatably sleeved on the medicine feeding tube 28, a clamping ring 271 is arranged at the upper end of the transmission sleeve 27, the clamping ring 271 is fixedly arranged at an opening at the upper end of the transmission sleeve 27 and positioned at the inner side of the transmission sleeve 27, and the clamping ring 271 is rotatably arranged in the annular groove 281, so that the transmission sleeve 27 can drive the medicine feeding tube 28 to synchronously move up and down and can rotate relative to the medicine feeding tube 28. The upper end of the transmission sleeve 27 is connected with the lower pressure plate 24, a first spiral groove 272 extending along the axial direction of the mounting shell 22 is arranged on the peripheral wall of the transmission sleeve 27, the first spiral groove 272 is communicated with the inner side of the transmission sleeve 27, and the rotation direction of the first spiral groove 272 extends upwards anticlockwise along the axial direction of the transmission sleeve 27. The transmission ring 26 is slidably sleeved on the transmission sleeve 27, and a plurality of transmission sliding blocks 261 are arranged on the inner wall of the transmission ring 26. One end of the transmission slide 261 is fixed on the transmission ring 26, the other end of the transmission slide 261 extends inwards to pass through the first spiral groove 272 and is inserted into the transmission groove 283, and each transmission slide 261 can pass through the first spiral groove 272 and is inserted into one transmission groove 283 so as to drive the transmission ring 26 to slide along the axial direction of the transmission sleeve 27 and drive the medicine feeding tube 28 to rotate when the transmission slide 261 slides downwards in the first spiral groove 272, and the transmission ring 26 rotates downwards clockwise when the transmission slide 261 slides along the first spiral groove 272. The power storage spring 25 is sleeved on the transmission sleeve 27 and is positioned between the lower pressure plate 24 and the transmission ring 26, the upper end of the power storage spring is connected with the lower pressure plate 24, and the lower end of the power storage spring is connected with the transmission ring 26 so as to enable the power storage spring 25 to store power when the transmission ring 26 slides upwards. The upper chamber assembly 21 is slidably mounted on the mounting housing 22 up and down and is configured to slide the drive ring 26 up the drive sleeve 27 when slid up, so as to disengage the drive ring 26 when the drive ring 26 is slid up to a predetermined value, thereby releasing the power spring 25.
In operation, the feeding tube 28 is inserted into the auditory canal and into the site to be fed, and the loading assembly 21 is slid upward along the mounting shell 22, and the loading assembly 21 slides upward and drives the drive ring 26 to slide upward. Since the lower platen 24 cannot move upward, the power spring 25 is compressed during the upward movement and rotation of the drive ring 26. When the loading assembly 21 drives the drive ring 26 to rise to a preset position, the power spring 25 is compressed to store power.

The spring force of the power storage spring 25 releases the elastic force to drive the ring 26 to have downward thrust, so that the ring 26 rotates clockwise to slide downwards on the transmission sleeve 27, and meanwhile, the power storage spring 25 has upward thrust to the lower pressure plate 24, so that the lower pressure plate 24 drives the transmission sleeve 27 to be unable to slide downwards. In the clockwise rotation of the transmission ring 26, the medicine feeding tube 28 is driven to synchronously rotate, so that the medicine 30 is ground into powder on the grinding knife 31, and the medicine is fed to the part needing to be fed in the auditory canal.
In this embodiment, as shown in fig. 2 to 4, a feeding spring 23 is provided in the installation housing 22, and the feeding spring 23 is vertically provided at an upper end connected to the top cover 32 of the installation housing 22 and at a lower end connected to the lower platen 24. The initial state of the feed spring 23 is in a compressed state so that after the medicine 30 is ground for a certain length, the feed spring 23 releases the elastic force to slide the lower platen 24 downward, so that the grinding blade 31 is ensured to grind the medicine 30 next time.
In this embodiment, as shown in fig. 1-7, the loading assembly 21 includes an inner slip ring 212 and an outer slip ring 211. A plurality of upper chamber grooves 223 are circumferentially and uniformly distributed on the peripheral wall of the installation shell, the upper chamber grooves 223 are used for communicating the inside of the installation shell 22, and the upper chamber grooves 223 are linear grooves and extend along the up-down direction of the installation shell 22. The outer sliding sleeve 211 is sleeved on the mounting shell 22 in a vertically sliding manner, a plurality of fixing rods 214 are fixed on the inner wall, and the fixing rods 214 are horizontally arranged. Each of the fixing rods 214 is slidably installed up and down in one of the upper bore grooves 223. The inner slip ring 212 is horizontally arranged in the mounting shell 22 and is positioned at the outer side of the driving ring 26, the outer sliding sleeve 211 is fixedly connected through the fixing rod 214, a one-way transmission component is arranged between the inner slip ring 212 and the driving ring 26, so that when the inner slip ring 212 slides upwards, the driving ring 26 is driven to move upwards, and when the inner slip ring 212 drives the driving ring 26 to move upwards to a preset position, the driving ring 26 and the inner slip ring 212 are separated from each other, and at the moment, the inner slip ring 212 displaces above the driving ring 26. Specifically, the outer sliding sleeve 211 is slid upward to drive the inner sliding ring 212 to slide upward, and simultaneously drive the driving ring 26 to move upward. When the medicine 30 needs to be ground again, the unidirectional transmission assembly contracts when the inner slide ring 212 slides downwards until the outer slide ring 212 moves the outer side of the transmission ring 26, and the outer slide sleeve 211 can slide upwards again.
In this embodiment, as shown in fig. 6 and 11, the unidirectional transmission assembly includes unidirectional sliding teeth 213 and unidirectional unlocking grooves 262, the number of the unidirectional sliding teeth 213 may be a plurality of unidirectional unlocking grooves 262 in a spiral groove shape, the unidirectional unlocking grooves 262 are disposed on the peripheral wall of the transmission ring 26, the unidirectional unlocking grooves 262 extend upwards spirally along the axial direction of the transmission shaft and extend upwards anticlockwise, and an opening is disposed at the upper end of the unidirectional unlocking grooves 262.

In the process of sliding up the inner slip ring 212, the unidirectional sliding teeth 213 are driven to slide in the unidirectional unlocking groove 262, and the transmission ring 26 rotates anticlockwise during sliding up, when the unidirectional sliding teeth 213 are separated from the unidirectional unlocking groove 262, the connection relationship between the transmission ring 26 and the inner slip ring 212 disappears, and the compression spring is released. The unidirectional unlocking grooves 262 can be uniformly distributed on the outer wall of the transmission ring 26, so that when the process of feeding and grinding is finished once, the transmission ring 26 rotates by a fixed angle relative to the feeding assembly 21, and then the unidirectional sliding teeth 213 on the next feeding assembly 21 can still be ensured to be clamped into the end positions of the other unidirectional unlocking groove 262, so that the power storage value of the power storage spring 25 driven by the next feeding assembly 21 is ensured to be unchanged.

Specifically, each of the single downward pressing teeth 224 has a ring-shaped tooth shape so as to be inwardly contracted when the single downward pressing teeth are subjected to downward pressure, and the spiral slider 242 and the single downward pressing teeth 224 cooperate so that the lower platen 24 can only move downward.
In this embodiment, as shown in fig. 4 and 5, the lower platen 24 and the transmission sleeve 27 are connected by an elastic telescopic rod 241, so that when the transmission sleeve 27 receives the upward thrust of the inner slip ring 212, the elastic telescopic rod 241 contracts, and then the transmission sleeve 27 drives the medicine feeding tube 28 to move upwards, so that a gap is kept between the medicine 30 and the grinding blade 31, and friction between the medicine 30 and the grinding blade 31 is avoided when the transmission ring 26 drives the medicine feeding tube 28 to rotate upwards.
