[0002] When medical staff prepare oral medications for infants and patients with severe dysphagia, they need to grind the medications into powder before giving them to the patients. Therefore, they need to use a medication grinding device to grind the medication particles.
[0003] When the existing drug grinding device grinds the drug, a large amount of fine powder will adhere to the uneven grinding surface of the grinding head, which is inconvenient to clean and will also cause the weight of the ground drug to change. If the powder is lost each time after grinding, the amount of medicine taken by the patient each time will decrease, resulting in poor efficacy. Therefore, a drug grinding device is proposed based on the above problems. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0021] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0022] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0025] The inner side of the seat body 2 is provided with a conical groove, and the lower side of the grinding disc 57 is a conical structure. The conical angle of the grinding disc 57 is set at the same angle as the conical groove angle of the seat body 2. Through this setting, the rotating grinding disc 57 and the seat body 2 can cooperate with each other to grind the medicine into powder. The inner side of the shell rod 55 is a square channel structure, and the square block 54 fits with the inner wall of the channel of the shell rod 55. Through this setting, the rotation of the shaft rod 52 can drive the shell rod 55 to rotate. The first spring 56 is set between the lower end surface of the square block 54 and the inner wall of the shell rod 55. Through this setting, the grinding disc 57 and the seat body 2 are tightly fitted. The second spring 64 is arranged between the lower end surface of the pressing block 62 and the upper end surface of the cover body 3, and the upper end surface of the guide block 63 is fitted with the inner wall of the cover body 3.

[0026] Workflow: The medical staff uses the drug grinding device to grind the drug as follows: first, place the drug to be processed in the conical groove of the seat body 2, install the cover body 3 and its auxiliary mechanism back on the tank body 1, and start the motor 51 of the grinding part 5 by pressing the switch, so that the shaft rod 52 drives the protrusion 53, the square block 54, the shell rod 55 and the grinding disc 57 to rotate, so that the rotating grinding disc 57 and the seat body 2 can cooperate to grind the drug into powder; after grinding, remove the cover body 3 to separate the grinding disc 57 from the seat body 2 up and down, and at this time, press the pressing block 62 of the extrusion part 6 to make the rod body 61 drive the guide block 63 to move downward, so that the guide block 63 and the protrusion 53 are at the same height position, and the protrusion 53 is affected by the shaft. The rod 52 rotates and moves in a circular motion. Since the guide block 63 and the protrusion 53 are at the same height, the circular displacement of the protrusion 53 will be squeezed by the guide block 63, causing the entire grinding section 5 to move to the left. When the protrusion 53 moves out of the influence of the guide block 63, the grinding section 5 will be reset to the right under the influence of the reset member 8, causing the grinding section 5 to vibrate left and right at high frequency during operation, thereby causing the grinding disc 57 to vibrate at high frequency, causing the drug powder adhered to the surface of the grinding disc 57 to fall off quickly and fall into the seat 2, completing the cleaning of the grinding disc 57 and the grinding of the drug. The drug grinding device can quickly and conveniently clean the grinding mechanism when grinding the drug to avoid loss of the ground drug.
