However, because both the crushing container and the crushing rod are made of hard materials, it is quite strenuous for medical staff to use the crushing rod to crush the drug, resulting in poor crushing effect and uneven drug crushing.

[0004] Therefore, there is an urgent need to design a crusher to solve the current shortcomings of poor crushing effect and time-consuming and labor-intensive operation of solid medicines. Utility Model Content

[0005] In view of this, the present invention provides a solid drug crusher that can more conveniently crush solid drugs.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A solid drug crusher, the key feature of which is that it includes a cup base and a crushing inner liner that can be slidably installed in the cup base. The crushing inner liner has a crushing chamber with an open upper end. The bottom of the crushing chamber is an arc-shaped groove structure. The surface of the arc-shaped groove structure is distributed with friction protrusions. An elastic component is installed between the bottom of the crushing inner liner and the cup base. The elastic component applies a thrust that causes the crushing inner liner to slide upward.

[0008] It also includes a crushing component, the lower part of which has a crushing protrusion adapted to the crushing chamber. The crushing protrusion can extend into the crushing chamber and rotate relative to the crushing chamber. The bottom of the crushing protrusion is provided with an arc surface structure similar to the arc-shaped groove structure, and friction protrusions are distributed on the surface of the arc surface structure.

[0009] After the solid drug is placed into the crushing chamber, the crushing protrusion is inserted to the bottom of the crushing chamber, which can push the crushing inner liner to slide downward, so that the elastic component is in a charged state.

[0010] Preferably, a first limiting structure is provided between the inner liner and the cup base, the first limiting structure being used to limit the distance the inner liner slides up and down along the cup base.

[0018] Preferably, the cup holder is formed by fastening together an upper structure and a lower structure.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. Using the solid drug crusher provided by this utility model, after multiple solid drugs are placed into the crushing chamber, the crushing protrusion of the crushing component is inserted to the bottom of the crushing chamber. The drug is sandwiched between the upper and lower friction protrusions. Since the elastic component is in a compressed and stored state at this time, it applies an upward thrust to the crushing inner chamber. Therefore, by repeatedly rotating the crushing component, the solid drug can be crushed under the upward thrust of the elastic component and the action of the upper and lower friction protrusions, thus achieving crushing and grinding.

[0028] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0029] like Figure 1 and 2 As shown, a solid drug crusher includes a cup base 1, a crushing inner liner 2, and a crushing component 3. The cup base 1 has a cylindrical structure, and the crushing inner liner 2 is slidably installed within the cup base 1. Figure 3 As can be seen, the inner crushing container 2 has a crushing chamber 21 with an open upper end. The bottom of the crushing chamber 21 is an arc-shaped groove structure 2a, and the surface of the arc-shaped groove structure 2a is distributed with friction protrusions a. An elastic component 4 is installed between the bottom of the inner crushing container 2 and the cup seat 1. This elastic component 4 applies a thrust that causes the inner crushing container 2 to slide upward. Furthermore, the lower part of the crushing component 3 has a crushing protrusion 31 adapted to the crushing chamber 21. This crushing protrusion 31 can extend into the crushing chamber 21 and rotate relative to the crushing chamber 21. The bottom of the crushing protrusion 31 has an arc surface structure similar to the arc-shaped groove structure 2a, and the surface of this arc surface structure is distributed with friction protrusions b. After the solid drug is placed into the crushing chamber 21, the crushing protrusion 31 is inserted to the bottom of the crushing chamber 21, which can push the inner crushing container 2 to slide downward, so that the elastic component 4 is in a stored state.

[0030] Based on the above structural design, after multiple solid drugs are placed into the crushing chamber 21, the crushing protrusion 31 of the crushing component 3 is inserted to the bottom of the crushing chamber 21, and the drugs are sandwiched between the upper friction protrusion b and the lower friction protrusion a (see reference). Figure 4 Since the elastic component 4 is in a compressed and stored state at this time, it applies an upward thrust to the inner liner 2. Therefore, by repeatedly rotating the crushing component 3, the solid medicine can be crushed under the upward thrust of the elastic component 4 and the action of the upper and lower friction protrusions, thus achieving crushing and grinding. It has the advantages of convenient operation, high crushing efficiency and good crushing effect.

[0031] Furthermore, a first limiting structure is provided between the crushing inner liner 2 and the cup base 1, which can limit the distance that the crushing inner liner 2 slides up and down along the cup base 1.

[0032] Specifically, refer to Figure 1 and 3 The first limiting structure includes a first annular boss 2b protruding outward along the circumferential direction of the upper end of the crushing chamber 21. The upper end of the cup seat 1 is open, and the open end of the upper end of the cup seat 1 is provided with a second annular boss 1b protruding inward along its circumferential direction. A slider 2c protruding radially outward is provided on the outer wall of the crushing inner liner 2. A sliding gap c is formed between the slider 2c and the first annular boss 2b. The second annular boss 1b is located between the slider 2c and the first annular boss 2b. Figure 3 As shown, before installing the crushing component 3, the elastic component 4 applies a force that causes the crushing inner liner 2 to slide upward, so that the upper surface of the slider 2c abuts against the lower surface of the second annular protrusion 1b. After the crushing protrusion 31 of the crushing component 3 is inserted into the bottom of the crushing chamber 21, the crushing component 3 is pressed down, which can drive the crushing inner liner 2 to slide downward along the height direction of the cup seat 1.

[0033] To ensure the smooth sliding of the inner liner 2 during crushing, combine as in 1 and Figure 4 As shown, the inner wall of the cup holder 1 is provided with a groove 1c extending along its height direction, and the slider 2c slides in conjunction with the groove 1c. In this embodiment, there are four sets of grooves 1c and sliders 2c, which correspond one-to-one, and the four sets of sliders 2c are symmetrically distributed around the circumference of the crushing inner liner 2. In this embodiment, the upper part of the crushing protrusion 31 and the crushing cavity 21 are both cylindrical structures. A large gap is reserved between the two cylindrical structures and between the slider 2c and the groove 1c to ensure that when the crushing inner liner 2 is repeatedly rotated, it can achieve a certain amount of shaking in the space under the pushing force of the elastic component 4 and the resistance of the solid drug to the upper and lower friction protrusions. This allows the drug to form a flowing state during the drug grinding process, improving the grinding effect and efficiency.

[0034] Please refer to Figure 1 and 3The upper end of the crushing component 3 is fixed with a cover 3a, which is a ring-shaped structure. After the crushing component 3 is installed, the inner wall of the ring-shaped cover 3a slides and engages with the outer wall of the cup holder 1, and the cover 3a can rotate relative to the cup holder 1. In use, pressing down on the cover 3a and then repeatedly twisting the cover 3a will crush the medicine. This installation structure can improve the stability of the rotation operation of the crushing component 3.

[0035] Revisit Figures 1 to 3 The upper outer side of the cup holder 1 is provided with an annular limiting part 1d protruding outward in the circumferential direction. One end of the cover 3a is provided with a downward extending locking strip 3a1. The lower end of the locking strip 3a1 is provided with a locking part d that is adapted to the bottom structure of the annular limiting part 1d. During operation, after the crushing component 3 is pressed down and the crushing inner liner 2 is slid down to the set position, the locking part d can be locked onto the annular limiting part 1d so that the crushing component 3 can be held at that height position. Then, by repeatedly twisting the cover 3a, the crushing component 3 is driven to rotate back and forth, so that the lower friction protrusion a and the upper friction protrusion b can repeatedly crush the medicine. This installation structure can further improve the stability of the rotation operation of the crushing component 3.

[0036] During the crushing process of solid drugs, the volume of the drug continuously shrinks, such as... Figure 5 As shown, the thrust applied by the elastic component 4 will push the inner liner 2 to slide upward, thereby reducing the space enclosed by the arc-shaped groove structure 2a and the bottom of the crushing component 3, ensuring that the medicine can be completely crushed, and further improving the crushing effect.

[0037] like Figure 3 and Figure 6 As shown, the lower friction protrusions a on the surface of the arc-shaped groove structure 2a and the upper friction protrusions b on the bottom arc-shaped structure surface of the crushing protrusion 31 are both distributed in a ring array. In this embodiment, the lower friction protrusions a and upper friction protrusions b are spatially alternately distributed. That is, when the crushing component 3 is inserted into the crushing inner liner 2 and the crushing component 3 is repeatedly rotated, the upper friction protrusions b at the bottom of the crushing protrusion 31 and the lower friction protrusions a on the surface of the arc-shaped groove structure 2a will not overlap. Through the continuous alternating friction of the upper friction protrusions b and lower friction protrusions a on the drug, a better crushing effect can be achieved.

[0038] like Figure 1 and Figure 3 As shown, the lower end of the crushing inner liner 2 is provided with a downward protruding first mounting structure 2d, and the bottom of the cup seat 1 is provided with an upward protruding second mounting structure 1a corresponding to the position of the first mounting structure 2d. The elastic component 4 is supported between the first mounting structure 2d and the second mounting structure 1a. The first mounting structure 2d and the second mounting structure 1a can prevent the elastic component 4 from shifting.

[0039] Depend on Figure 1 and Figure 3As can be seen, in this embodiment, the crushing component 3 has a drug storage space 3b in the middle, and a sealing cover 3e is provided on the top of the drug storage space 3b. The drug storage space 3b can be used to store drugs, which increases the function of the solid drug crusher.

[0040] For ease of processing and assembly, refer to Figure 1 and Figure 3 The cup holder 1 is formed by fastening together an upper structure 11 and a lower structure 12.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
