Technical Field
[0001] This utility model relates to the technical field of portable tablet crushers, and in particular to a portable tablet crusher. Background Technology
[0002] A tablet pulverizer is a device that crushes quick-packaged tablets into powder. The tablet is placed inside the pulverizer, and the screw is turned by hand, causing the tablet to be crushed by the pressure plate inside the pulverizer, thus achieving the pulverizing effect.
[0003] The inventor discovered during routine use of the tablet crusher that, because the tablets are crushed by squeezing, some drug powder adheres to the surface of the pressure plate. This powder may react with other tablets when crushing them, rendering the tablets unusable and causing adverse effects. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a portable tablet crusher.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable tablet crusher, comprising a crusher, one end of which is threadedly connected to a medicine box, a screw threadedly connected to the surface of the crusher, a pressure plate fixedly connected to one end of the screw, an isolation device provided on the surface of the pressure plate, the isolation device comprising an isolation membrane sleeved on the surface of the pressure plate, and a leather ring fixedly connected to one end of the isolation membrane.
[0006] The aforementioned components achieve the following effects: Under the action of the leather ring, the separating membrane can be fitted onto the surface of the pressure plate, preventing the tablets from contacting the pressure plate and adhering to its surface. When tablets need to be crushed, the tablets are placed inside the pill holder, and the pill holder is screwed onto the crusher. Holding the crusher with one hand and turning the screw with the other, the pressure plate is pressed into the pill holder, thus crushing the tablets into powder. Due to the small size of the crusher, it is portable.
[0007] Preferably, a film is fixedly connected to one end of the pressure plate, and the film is fixedly connected to the surface of the release liner.
[0008] The effect achieved by the above components is that, under the action of the film, the release liner adheres to the surface of the pressure plate, thereby preventing the powder from coming into contact with the pressure plate.
[0009] Preferably, a rubber ring is fixedly connected to the side of the isolation membrane, and one end of the rubber ring is fixedly connected to the top of the pressure plate.
[0010] The effect achieved by the above components is that, under the action of the rubber ring, the release liner will not wrinkle on the surface of the pressure plate, thereby achieving the function of fixing the release liner.
[0011] Preferably, the surface of the screw is provided with an annular groove, and a rubber band is provided inside the annular groove.
[0012] The effect achieved by the above components is that, under the action of the annular groove and the elastic band, the opening of the isolation membrane is fixed inside the annular groove, thereby achieving the function of fixing the isolation membrane.
[0013] Preferably, a rubber ring is fixedly connected to the inner wall of the annular groove, and the rubber ring is evenly arranged inside the annular groove.
[0014] The aforementioned components achieve the following effects: The rubber ring prevents the release diaphragm from sliding inside the groove, thus avoiding slippage. When isolation of the pressure plate is required, the release diaphragm is fitted onto the surface of the pressure plate. The rubber ring ensures the release diaphragm is securely fitted onto the pressure plate surface. The adhesive film adheres the release diaphragm to the pressure plate surface, preventing contact between the powder and the pressure plate. The rubber ring prevents the release diaphragm from wrinkling on the pressure plate surface, thus fixing the release diaphragm in place. A rubber band is fitted onto the release diaphragm surface, securing it inside the groove. The rubber ring prevents the release diaphragm from sliding inside the groove, thus achieving the isolation effect.
[0015] Preferably, the surface of the pulverizer is provided with an anti-slip device, the anti-slip device including an anti-slip ring sleeved on the surface of the pulverizer, and an anti-slip strip fixedly connected to the surface of the anti-slip ring.
[0016] The effect achieved by the above components is that, under the action of the anti-slip strips and anti-slip rings, the pulverizer will not slip when the tablets are crushed.
[0017] Preferably, a rectangular strip is fixedly connected to the surface of the pulverizer, and a round strip is fixedly connected to the inner wall of the anti-slip strip, with the round strip and the rectangular strip arranged alternately.
[0018] The effect achieved by the above components is that, under the action of the round and rectangular bars, the pulverizer and the anti-slip ring will not rotate, thereby preventing the pulverizer from rotating when pulverizing tablets.
[0019] Preferably, a baffle is fixedly connected to the side of the pulverizer, and the baffle is disposed at both ends of the anti-slip ring.
[0020] The aforementioned components achieve the following effects: The baffle prevents the anti-slip ring from slipping off the surface of the pulverizer. When pulverizing tablets to prevent slippage, the anti-slip ring is fitted onto the surface of the pulverizer. The anti-slip strips and the anti-slip ring prevent the pulverizer from slipping during tablet crushing. The round and rectangular strips prevent rotation between the pulverizer and the anti-slip ring, thus preventing rotation of the pulverizer during tablet crushing. The baffle also prevents the anti-slip ring from slipping off the surface of the pulverizer, achieving an anti-slip effect.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting up an isolation device, when it is necessary to isolate the pressure plate, an isolation film is fitted onto the surface of the pressure plate. Under the action of the rubber ring, the isolation film can be fitted onto the surface of the pressure plate. Under the action of the film, the isolation film adheres to the surface of the pressure plate, thereby preventing the powder from contacting the pressure plate. Under the action of the rubber ring, the isolation film is prevented from wrinkling on the surface of the pressure plate, thus achieving the function of fixing the isolation film. The rubber band is fitted onto the surface of the isolation film, thereby making the rubber band stuck inside the ring groove. Under the action of the rubber ring, the isolation film is prevented from sliding inside the ring groove, thus avoiding the phenomenon of sliding, thereby achieving the isolation function. This solves the problem that the pressure plate easily picks up drug powder when pressing drugs, which may cause drug reactions when pressing other tablets, thus making the tablets unusable.

[0030] Working principle: When using the portable tablet crusher 1, to crush tablets, place the tablets inside the pill holder 5, screw the pill holder 5 onto the crusher 1, hold the crusher 1 with one hand and turn the screw 4 with the other, causing the pressure plate 6 to press into the pill holder 5, thus crushing the tablets into powder. Due to the small size of the crusher 1, it achieves portability. When it is necessary to isolate the pressure plate 6, a release liner 21 is fitted onto the surface of the pressure plate 6. The rubber ring 22 allows the release liner 21 to fit onto the surface of the pressure plate 6, and the adhesive film 23 makes the release liner 21 adhere to the surface of the pressure plate 6, thus preventing the powder from contacting the pressure plate 6. The rubber ring 27 prevents the release liner 21 from wrinkling on the surface of the pressure plate 6, thus securing the release liner 21. The function is to place the rubber band 25 on the surface of the separating membrane 21, thereby locking the rubber band 25 inside the annular groove 24. Under the action of the rubber ring 26, the separating membrane 21 will not slide inside the annular groove 24, thus avoiding the phenomenon of sliding and achieving the function of isolation.
