Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Example

[0045] See also Figure 1-Figure 12 , the present invention provides the following technical solutions:

[0046] A medicine grinding device for wound repair, comprising:

[0047] Medicine grinding box 1;

[0048] The connecting box 101 is arranged on the upper side of the medicine grinding box 1, and the upper end of the connecting box 101 is fixedly connected with the annular rotating block 113, and the upper end of the connecting box 101 is fixedly connected with a plurality of limiting sliding grooves 302;

[0049] The brewing box 2 has an annular rotating groove 112 at the lower end thereof, and an annular rotating block 113 rotates in the annular rotating groove 112;

[0050] The limiting ring 3 is slidably connected to the circumferential outer surface of the connecting box 101 and the brewing box 2. A plurality of limiting sliders 301 are provided at the lower end of the limiting ring 3. The plurality of limiting slide grooves 302 slide in the plurality of limiting sliders 301 respectively.

[0051] The grinding mechanism is arranged in the medicine grinding box 1. When grinding, the brewing box 2 is fixed and the medicine grinding box 1 rotates, and then the blades in the grinding mechanism grind the tablets into powder;

[0052] The feeding mechanism is connected to the grinding mechanism. When the tablets are ground into powder, the feeding mechanism rotates synchronously with the medicine grinding box 1 and feeds the medicine powder into the brewing box 2 through the spiral feeding device;

[0053] The limiting mechanism is arranged in the brewing box 2 and the connecting box 101. The limiting mechanism includes two groups of connecting components and two groups of closing components. When it is necessary to feed the medicine powder, the connecting port in the brewing box 2 and the medicine grinding box 1 is opened by the spring thrust of the connecting component, so that the feeding mechanism can feed the tablet powder into the brewing box 2. When it is necessary to brew the medicine liquid, the closing component closes the connecting channel between the medicine grinding box 1 and the brewing box 2 and then closes the brewing box 2 for brewing the medicine powder.

[0054] In a specific embodiment of the present invention, the medicine grinding box 1 contains a grinding chamber and a conveying chamber for tablets, and the brewing box 2 is used to brew medicine powder. The annular rotating block 113 rotates in the annular rotating groove 112 to connect the medicine grinding box 1 and the brewing box 2. When the connecting box 101 slides on the outer surfaces of the medicine grinding box 1 and the brewing box 2, the upper and lower ends are limited in sliding distance by the medicine grinding box 1 and the limiting ring 3. The limiting slide groove 302 is provided at the upper end of the connecting box 101 and the lower end of the limiting ring 3. The limiting slider 301 provided in the limiting ring 3 slides on the outer surface of the limiting slide groove 302 to limit the rotation of the limiting ring 3 so that the limiting ring 3 can only move up and down. When tablet grinding is not required, the limiting ring 3 is provided on the outer surface of the brewing box 2, and the trapezoidal block 306 is pushed by the reset spring 308. The limiting ring 306 is pushed completely into the fixing groove 310 by the limiting ring 3, so that the medicine grinding box 1 cannot rotate at the lower end of the brewing box 2. At this time, the connecting hole 309 is misaligned with the medicine feeding groove 110, and the isolating slide 305 separates the medicine feeding groove 110 from the flushing cavity of the brewing box 2 and the medicine grinding box 1. When the tablets need to be ground, the tablets are first put into the medicine grinding box 1 from the medicine feeding port 114, and the larger tablets fall between the conveying sleeve 107 and the inner wall of the medicine guiding groove 102. Then the operator presses the pushing blocks 311 from both sides, and pushes the trapezoidal blocking block 306 completely into the blocking groove 304 by the pushing block 311 to release the fixed restriction on the limiting ring 3, and then slides the limiting ring 3 downward to the connecting box 101. The outer surface of the trapezoidal block 306, after there is no limit on the outer side of the limiting ring 3, the return spring 308 pushes the trapezoidal block 306 outward until the blocking block 307 is stuck on the inner wall of the blocking groove 304. At this time, the connecting hole 309 coincides with the medicine feeding groove 110, the medicine grinding box 1 and the brewing box 2 are connected, and the limiting ring 3 and the medicine grinding box 1 are no longer restricted by the trapezoidal block 306. The medicine grinding box 1 is rotated to grind the tablets between the medicine guide groove 102 and the conveying sleeve 107 through the medicine grinding blade 109. The distance between the medicine guide groove 102 and the conveying sleeve 107 becomes narrower and narrower from top to bottom. The tablets ground into small pieces continue to fall to the bottom of the medicine guide groove 102 and are stuck on the inner wall of the medicine guide groove 102 and continue to be ground until the tablets are ground into powder and fall into the powder groove 103. 104 and the conveying blade 105 rotate with the medicine grinding box 1. When the medicine powder passes through the lower opening of the conveying trough 108, the medicine powder is conveyed upward by the rotating conveying blade 105. The outer surface of the anti-drop plate 106 fits with the inner wall of the conveying trough 108, so that the medicine powder cannot fall after being conveyed to the conveying trough 108. After the medicine powder is conveyed to the top of the conveying trough 108 by the conveying blade 105, it is squeezed and pushed by the subsequent medicine powder, and squeezed into the medicine flushing trough 111 from the medicine feeding trough 110. When a certain amount of medicine powder is accumulated in the medicine flushing trough 111, the operator slides the limiting ring 3 upward. The contact surface between the side end of the trapezoidal block 306 and the limiting ring 3 is an inclined surface. The limiting ring 3 pushes the trapezoidal block 306 into the clamping groove 304, and the connecting hole 309 is misaligned with the medicine feeding trough 110 again.The lower end of the brewing box 2 is blocked, and the limiting ring 3 is again limited by the trapezoidal block 306 and cannot rotate or move downward. At this time, the powder in the brewing box 2 can be flushed with water and taken.

[0055] For details, please refer to Figure 1-Figure 12 The grinding mechanism includes a medicine introducing groove 102, a medicine powder groove 103, a conveying sleeve 107, a medicine grinding blade 109 and a medicine inlet 114.
