As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
In a practical or designed tamping device, the shape of the canister 200 and the pestle 100 can have a significant effect on the tamping process. Referring to fig. 1, if the cavity 210 of the container 200 is cylindrical, the ram 110 of the pestle 100 is also cylindrical, or the contact surface between the ram 110 and the cavity 210 is flat, which is not easy to operate for pounding medicine. The difficulty lies in that the bottom surface of the hammer head 110 is a plane, the bottom surface of the inner cavity 210 of the tank body 200 is also a plane, and in the process of pounding the medicine, the medicine pestle can be axially moved to ensure that the plane of the bottom surface of the hammer head 110 is just in contact with and stressed on the parallel state with the bottom surface of the inner cavity 210, so that the hammer head 110 can be ensured to contact with the medicine as much as possible, the side edge of the bottom surface of the hammer head 110 can be ensured not to be in direct contact with the bottom surface of the inner cavity 210 as much as possible, and the hammer head 110 and the inner cavity 210 are protected from deformation or rigid contact loss. However, the precision and long-term wear of the plunger 100 are problems that the plunger is difficult to move axially, and the cylindrical ram 110 and the inner cavity 210 are not suitable for small amounts of medicinal materials. In addition, as shown in fig. 2, if the conical inner cavity 210 and the hammer head 110 are used for increasing the size of the hammer head 110 and the inner cavity 210, the tip of the hammer head 110 is easily worn, but the medicinal material is pressed against the side wall of the inner cavity 210 when the hammer head 110 is impacted and squeezed, so that the amount of the medicinal material contacted by the hammer head 110 and the inner cavity 210 in a single impact is increased. Therefore, the impact and grinding area can be increased more in the bottomless hammer head 110 and the inner cavity 210. But the bottomless hammer head 110 and the tip of the cavity 210 are very susceptible to wear if the axes do not coincide upon impact. Compared with the first two hammers 110 and the inner cavity 210, the impact of 1 plane contact with the medicinal materials is positive pressure, the shearing force is small, the crushing effect is common, the contact surface is small, and the grinding effect under positive contact is worse; 2. the conical surface has obvious shearing action when contacting with medicinal materials, and the relatively larger contact surface between the hammer head and the inner cavity has obvious grinding effect; 3. the simple surface contact has large loss of the hammer head and the inner cavity and large operation difficulty, and all have the problems mentioned in the background technology, namely that the medicinal materials are easy to burst out and/or splash.
Of course, the prior art does not use cylindrical and conical hammers and cavities, but designs the contact surface as a cambered surface. Meanwhile, the contact surface between the bottom of the cavity 210 and the hammer head 110 is not the same as that shown in fig. 1-2 (the shape and/or size of the hammer head 110 and the cavity 210 are the same), and the size of the hammer head 110 in the prior art is much smaller than that of the bottom of the cavity 210, as shown in fig. 3. This results in the drug material having a tendency to move up the walls of the cavity 210 upon impact, and easily burst or splash if not restrained.
Based on fig. 1-3, it can be seen that the larger the axial depth of the inner cavity and the ratio of the top opening, the less the medicinal material is easy to fly out of the inner cavity, and the closer the shape and size of the hammer head 110 and the inner cavity 210, especially the bottom of the inner cavity 210, are, the higher the probability of the material being extruded and rubbed and the lower the probability of the material being blown out of the inner cavity. First, in order to improve the crushing efficiency of the medicinal materials, it is certainly better to have the shape and size of the hammer head 110 and the bottom of the inner cavity 210 closer to each other, but why is the prior art not adopted? The reason is that the higher the consistency of the shape and size of the bottom of the hammer head 110 and the inner cavity 210, the more difficult the use, because the higher the consistency of the shape and size of the bottom of the hammer head 110 and the inner cavity 210, the more limited the direction of the hammer head 110 moving relative to the inner cavity 210, as shown in fig. 1-2, the impact surfaces are determined, if the impact surfaces are matched to a greater extent, firstly, the medicinal material may not be impacted, and secondly, the hammer head and the inner cavity are in direct contact, and the rigid impact of the two contact surfaces causes loss. Therefore, in the prior art, the bottom of the cavity 210 is much larger than the hammer head 110 to compromise the effect of manual operation.
In order to prevent the block or granular medicinal materials from being broken out, the fresh medicinal material juice does not splash. The hammer head 110 is designed into two parts, including a soft body part 111 and a heavy hammer part 112, the soft body part 111 is wrapped outside the heavy hammer part 112, the soft body part 111 is filled with gas or liquid and then becomes a sphere, the soft body part 111 is used for basically positioning the medicinal material on the inner wall of the inner cavity 210 of the tank body 200 when contacting the medicinal material, and then the heavy hammer part 112 closely follows the hammered medicinal material. The soft body 111 and the weight 112 are spherical at least in the lower half and are fixed to the end of the pestle 120. Meanwhile, the inner cavity 210 of the can 200 at least includes an opening 211 and an impact part 213, the opening 211 is large at the top and small at the bottom for facilitating the entry of the hammer head 110, and the impact part 213 is also convenient to display, the impact part 213 is the inner side surface of the bottom of the inner cavity 210, the impact part 213 is a spherical surface, the spherical surface diameter of the impact part 213 is 1-1.2 times the diameter of the soft body part 111, the diameter of the lower sphere part of the weight part 112 is smaller than the inner diameter of the lower sphere of the soft body part 111, and can be 0.6-0.8 times the inner diameter of the lower sphere.
Thus, in use, as shown in fig. 4-5, the hammer head 110 falls, the soft body 111 contacts the medicinal material first, and the medicinal material can be squeezed on the inner wall of the impact portion 213 because the soft body can deform, and then the heavy hammer portion 112 hammers the medicinal material. The soft body 111 external diameter is the same basically with impact portion 213 internal diameter, contradicts impact portion suddenly under the soft body 111 inertia effect moreover, and the effect that the part deformation external diameter grow that is located the upside of impact portion 213 can play the closing cap impact portion avoids the medicinal material to break out and the juice splashes. In addition, the lower parts of the weight part 112 and the soft body part 111 are both spheres, so that the requirement on the angle of the hammer head 110 during falling is not strict, the inclined angle can be well attached to the impact part, and the rapid crushing is realized. In addition, the soft body 111 is very suitable for crushing fresh grass leaves, the grass leaves can be ground by rotating the hammer head 110 after being extruded, and juice cannot splash.
As shown in fig. 4 to 6, for convenience of operation or hammering at various angles, the weight part 112 may be a sphere, the soft body 111 is also a sphere after being filled with gas or liquid, and the outer diameter of the soft body 111 after being filled with gas or liquid is equal to the inner diameter of the impact part 213.
In order to avoid the medicine material from being broken and splashed, the inner cavity 210 further comprises a connecting part 212, and the connecting part 212 is positioned between the opening part 211 and the impact part 213; the connecting part 212 protrudes into the inner cavity 210, and the minimum inner diameter of the connecting part 212 is not less than the maximum outer diameter of the soft body part 111; the impact part 213 is an 1/2 spherical surface; the longitudinal height of the impact portion 213 is the longitudinal height of the lumen 1/4-1/3, as shown in FIG. 4. The depth of the cavity is increased, and the hammer head 110 can be guided to fall through the connecting part 212, and the soft body part 111 is assisted to cover the impact part.
The soft body part may be a rubber ball, but the rubber ball is easily worn or broken in actual use, so as shown in fig. 6 to 7, the soft body part 111 is provided with a multi-layer structure including a metal dense mesh 1111, an elastic layer 1112, and a metal cloth 1113;
the metal dense net 1111 is the outermost layer of the soft body part 111, and the metal dense net 1111 is used for directly contacting with the medicinal material to maintain the strength of the soft body part 111;
the elastic layer 1112 is positioned inside the metal dense mesh 1111 and is used for maintaining the sealing performance of the soft body part 111;
the metal cloth 1113 is located inside the elastic layer 1112 and is used for bearing the impact of the weight part 112.
The pore diameter of the metal dense mesh 1111 is not more than 0.3 mm; the metal dense mesh 1111 can have two layers, and the included angle between the warp and the weft of the two layers of metal dense mesh 1111 is 30-60 degrees.
The metal wire content of the metal cloth 1113 is 6%, and the metal cloth 1113 can also have multiple layers. The elastic layer 1112 is prevented from being pierced or worn by the metal dense mesh 1111 and the metal cloth 1113. Of course, the metal cloth can be any wear-resistant and impact-resistant material.
In practical use, because the medicinal materials are different, such as round particles and irregular particles, or the amount of the pounding medicine for one time is different, the space of the inner cavity 210 does not need to be as large, and the inner cavities of the round particles or the medicinal materials with small amount are smaller, which is more favorable for the pounding operation. Therefore, the pestle 120 is hollow to form a storage space, and is communicated with the cavity between the soft body 111 and the weight 112, and a solenoid valve is fixedly arranged at the communication position (the circuit connection of the solenoid valve is very simple and not shown in the figure, and simple circuit components including a power supply position and the like are also shown, and the prior art is very mature), and a solenoid valve switch is fixedly arranged on the pestle 120; the plunger thus receives and cushions the gas or liquid within the body 111 in preparation for deformation of the body.
Further comprises a sleeve 130, wherein the sleeve 130 comprises a positioning ring 131 and a tube body 132;
the positioning ring 131 and the pestle rod 120 can be axially positioned on the sleeve 130, the pipe body 132 is sleeved outside the pestle rod 120, and the top end of the pipe body 132 is fixedly connected with the positioning ring 131 through a tension spring; the positioning ring can be connected with the pestle rod 120 through threads or a buckle, so that the positioning effect is achieved.
The top end of the soft body 111 is fixed on the outer surface of the pestle 120 in a sealing way, and a part of the soft body 111 is always positioned in the pipe 132. As shown in fig. 8 to 9, the soft body portion 111 is a bag having a bottom portion of a hemisphere, and a shape of a water drop after being filled with air or liquid. The top end of the soft body 111 is fixed on the outer wall of the pestle 120, the soft body 111 is pressed by moving the sleeve 130 up and down, the solenoid valve is opened, and the gas or liquid in the soft body can enter the storage space of the pestle 120. When the volume of the soft body part needs to be enlarged, the sleeve 130 is moved upward, and the gas or liquid stored in the pestle rod 120 can enter the soft body part 111. When the volume of the soft body part 111 needs to be reduced, the sleeve 130 is moved downwards, the soft body part 111 is squeezed, gas or liquid in the soft body part 111 enters the storage space in the pestle 120, and the electromagnetic valve is closed after the required volume is achieved. Furthermore, since the tube 132 and the positioning ring 131 are fixed by the tension spring, when the pestle 100 falls down and abuts against the impact portion, the tube 132 continues to move downward, and the soft body 111 is pressed to deform in the horizontal direction, thereby covering the impact portion 213.
Certainly, in order to cooperate with the crushing and grinding of the medicinal materials, as shown in fig. 9, the inner cavity 210 can be better deformed, the inner cavity 210 is made of an elastic material, a liquid filling cavity is formed between the inner cavity 210 and the inner wall of the tank body 200 in a hollow manner, the liquid filling cavity is sealed and separated by a partition plate, a buffer cavity 220 is arranged below the liquid filling cavity, the buffer cavity 220 is communicated with the liquid filling cavity through a pipeline, and a pump is arranged on the pipeline and used for filling and discharging liquid in the liquid filling cavity; the liquid fills the non-Newtonian fluid filled cavity. The soft body portion 111 is filled with a non-newtonian fluid. There are many materials for non-Newtonian fluids and D3O is commercially available and is suitable for use. Fill non-Newtonian fluid, the effect is better compared with gas and ordinary liquid, because it still has little deformation in the part that receives the impact itself, other parts that do not receive the impact can deform to make the medicinal material be difficult to break out and splash away, receive the place of impact and the cooperation of weight portion 112 moreover and can better transmission impact force, broken speed is faster. To avoid damage to the impact portion 213, a backing plate 214 may be placed according to the size of the internal cavity.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
