Description

Technical Field

[0001] The utility model relates to a Chinese medicine preparation mechanism, in particular to a stirring mechanism for Chinese medicine preparation. Background Art

[0002] In the process of preparing paste-like Chinese medicine, it is often necessary to add glycerol to Chinese medicine powder, which can not only play the role of moisturizing and locking water, but also can play the role of lubrication, promoting wound healing and relieving skin inflammation in the prepared Chinese medicine. However, the existing glycerol addition is mainly based on the subjective judgment of medical staff, and the problem of inaccurate glycerol addition is very likely to occur. If the amount of glycerol added is too much, the prepared plaster is too thin and rotten, which is not conducive to later storage. If the amount of glycerol added is less, the prepared plaster is too dry and hard, which is not conducive to later use. In addition, when the Chinese medicine powder is stirred and mixed in the stirred tank, it is easy to rise and adhere to the wall of the tank, and then this part of the Chinese medicine powder is difficult to mix in, resulting in the waste of Chinese medicine powder. Utility Model Content

[0003] The utility model aims to provide a stirring mechanism for preparing traditional Chinese medicine, which can realize accurate addition of glycerin and reduce waste of traditional Chinese medicine powder.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] Preferably, at least one positioning protrusion is arranged on the end surface of the outer pot, and a positioning hole for inserting the positioning protrusion is opened on the outer edge of the inner pot.

[0010] Preferably, a discharge channel connecting the inside and outside of the inner pot is also provided at the bottom of the inner pot, and a plunger valve is also provided under the inner pot. The plunger of the plunger valve extends into the discharge channel to control the opening and closing of the discharge channel. A connecting terminal is also provided at the bottom of the outer pot. After the inner pot is placed in the outer pot, the connecting terminal is inserted into the discharge channel, and the outer end of the connecting terminal is connected to an output pump arranged on the outer pot.

[0011] Compared with the prior art, the beneficial effect of the utility model is that through the above scheme, the accurate distribution of the glycerol supply according to the weight of the Chinese medicine is achieved during the preparation of Chinese medicine, thereby ensuring the quality of the preparation of Chinese medicine.

[0017] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0018] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] like Figures 1 to 4 The stirring mechanism for preparing Chinese medicine shown in the figure comprises a scale body 100, and an outer kettle 200 is connected to the top of the scale body. A motor 1200 is installed at the bottom of the outer kettle, and the output shaft of the motor extends vertically upward and has a tenon for embedding. Figure 3 As shown, an inner liner 1100 is slidably placed in the outer kettle, and the inner surface of the inner liner has a non-stick coating 1120 to reduce the adhesion of the Chinese medicine powder to the inner wall of the inner liner during the mixing process of the Chinese medicine powder and glycerin.

[0021] It should be noted that the scale is an electronic scale with a tare weighing function so as to accurately weigh the weight of the Chinese medicine powder added to the inner tank each time.

[0022] In addition, in order to facilitate the uniform mixing of the Chinese medicine powder and glycerin in the inner pot, a stirring paddle 800 is rotatably installed at the bottom of the inner pot. After the rotating shaft of the stirring paddle extends downward to the bottom of the inner pot, it is detachably connected to the tenon on the motor to achieve uniform rotation in the inner pot under the drive of the motor. In order to prevent the stirring paddle from driving the inner pot to rotate with it, at least one raised positioning protrusion 210 is provided on the end face of the outer kettle, and a positioning hole 1110 adapted to the positioning protrusion is provided on the extension of the inner pot. It should be noted that when the inner pot is placed in the outer kettle, the positioning protrusion is inserted into the positioning hole to prevent relative rotation between the inner pot and the outer kettle, thereby preventing the inner pot from being driven by the rotating stirring paddle.

[0023] It should also be noted that when the stirring paddle stirs the Chinese medicine powder in the inner container, the Chinese medicine powder is easily lifted up. In order to prevent the Chinese medicine powder from being lifted up into the air, a sealing cover 300 is also sealed on the port of the outer kettle to seal the ports of the outer kettle and the inner container when the Chinese medicine powder is stirred. Figure 1 As shown, the sealing cover and the outer kettle are detachably connected via a buckle.

[0024] like Figure 2 , Figure 3 As shown, a metering pump 500 is also installed on the top of the sealing cover. The metering pump can be a peristaltic pump or an electric infusion pump with a precise delivery amount, so as to accurately pump the amount of glycerin required for stirring the Chinese medicine powder into a paste into the inner container before stirring the Chinese medicine powder. It should be noted that, Figure 4 As shown, a screw sleeve is provided on the side of the metering pump, which is connected to the liquid inlet end of the metering pump. A storage tank 600 is detachably screwed in the screw sleeve, and a certain amount of glycerin is stored in the storage tank to continuously provide sufficient glycerin for the metering pump; and the output end of the metering pump passes through the sealing cover and then into the inner tank, so that the pumped glycerin can be dripped into the inner tank.

[0025] It should be noted that in this solution, a control panel 400 installed on the sealing cover 300 is used to accurately control the amount of glycerol output by the metering pump. The control panel is connected to the metering pump 500 by electrical signals to achieve accurate control of the amount of glycerol pumped out by the metering pump. It should be noted that in this solution, the proportion of the amount of glycerol added in the control panel can be preset, such as an integer ratio of 1:4 to 10, and can also be flexibly adjusted through the built-in adjustment button. In order to simplify the control, a battery 700 that can be repeatedly charged and discharged is also installed on the sealing cover. The battery is electrically connected to the metering pump and the control panel through a wire to provide a stable and continuous amount of electricity to the control panel and the metering pump.

[0026] In the present solution, it should also be noted that if the Chinese medicine powder is directly placed in the inner tank and stirred with the dripped glycerin, the Chinese medicine powder is relatively light and is easily lifted up during the stirring process and adsorbed to the wall of the inner tank, thereby causing a waste of the Chinese medicine powder. After the Chinese medicine powder is adsorbed on the wall of the inner tank, when the sealing cover is subsequently opened, the airflow entering will cause this part of the Chinese medicine powder to float into the environment.

[0027] This solution was designed with this situation in mind, and in order to avoid this situation. In this solution, a gland 1000 is also designed, which is placed in the inner liner, and the outer edge is in sealing contact with the inner wall of the inner liner in a sliding manner, so that the gland can slide up and down in the inner liner. At the same time, the input of glycerol is achieved when mixing and stirring the Chinese medicine powder. That is, there is no need to add glycerol first, then open the sealing cover, and then put the gland in the inner liner. In this solution, an infusion tube 130 connected to the output end of the metering pump is also provided, and the infusion tube slides through the lower part of the sealing cover so that the glycerol pumped out by the metering pump can be directly delivered to the Chinese medicine powder through the gland. It should be noted that in order to prevent the sealing cover from slipping off the infusion tube, the lower end of the infusion tube has a blocking ring.

[0028] In addition, it should be noted that, in the present solution, in order to better enable the pressure cover to have a certain pressure on the Chinese medicine powder that needs to be stirred and mixed, a plurality of counterweight blocks 900 are also provided on the pressure cover.

[0029] Depending on the material of the Chinese medicine powder, the pressure from the gland on the Chinese medicine powder is preferably flexible and adjustable. To this end, the counterweight block is detachably connected to the upper surface of the gland. Preferably, a plurality of magnetic sheets 1010 can be provided on the upper surface of the gland. At the same time, the material of the counterweight block 900 is made of a metal material that can be magnetically attracted, so that the counterweight block can be removed and adsorbed on the gland.

[0030] In addition, on the basis of the above scheme, in order to realize the quantitative discharge of the medicine after the configuration is completed, the present scheme also has the following structure. Specifically, a discharge channel 1130 is also opened at the bottom of the inner liner 1100, and the two ends of the discharge channel extend to the inside of the inner liner and the outside of the inner liner respectively, so as to connect the inside and outside of the inner liner through the discharge channel. At the same time, a connecting terminal 220 is arranged at the bottom of the outer kettle 200. The connecting terminal is a cylindrical tube, which is arranged through the bottom of the outer kettle to connect the inside and outside of the bottom of the outer kettle. It should be noted that when the inner liner is placed in the outer kettle, the upper end of the connecting terminal is sealed and inserted into the outer end of the discharge channel to realize the connection with the discharge channel. In addition, it should be noted that if Figure 3As shown, an output book 1500 is also installed outside the outer kettle, and the output pump can be a plunger pump, paste pump, etc. for quantitatively outputting paste materials to take out the configured medicine from the inner tank. In addition, it should be noted that in order to prevent the material from entering the discharge channel when the medicine is stirred and configured, a plunger valve 1400 is also installed at the bottom of the inner tank, and the plunger of the plunger valve is inserted into the inner side end of the discharge channel 1130 to control the connection state between the discharge channel and the inner tank. It should be noted that in this scheme, the plunger valve and the output pump are both electrically connected to the scale body in this scheme to realize the sharing of power supply. In addition, the plunger pump is electrically connected to the scale body through a plug, that is, in this scheme, before the inner tank is placed in the outer kettle, the plug-in terminal extending from the plunger pump (which is provided by the plunger pump, not shown in the figure) can be connected to the plug-in interface on the scale body, and when the inner tank is taken out for cleaning, the plug-in terminal can be pulled out and separated from the plug-in interface on the scale body. The output pump is directly connected to the scale body. When the drug needs to be quantitatively discharged, the output pump drives the plunger pump to retract so that the discharge channel is connected. At this time, the drug in the inner container will be pressed into the discharge channel due to the pressure applied by the upper gland, which is convenient for the output pump to discharge. It should be noted that in order to facilitate the convergence of the drug into the discharge pipe, the inner end of the discharge pipe is set as far as possible in the middle of the bottom of the inner container, and the bottom of the inner container is concave downward in a conical shape, so that the paste-like drug can converge to the middle by its own gravity.

[0031] Working principle: When it is necessary to mix the Chinese medicine powder and glycerin, first remove the sealing cover. Then open the scale body and peel and set it to zero. Next, place the Chinese medicine powder in the inner tank, and weigh the weight of the added Chinese medicine powder through the scale body. After the above steps are completed, the sealing cover is re-covered on the outer kettle. At the same time, the pressure cover is slid into the inner tank so that the inner tank is sealed. It should be noted that because the inner wall of the inner tank is coated with a non-stick coating, it is relatively smooth and has a low friction coefficient. Therefore, the pressure cover can slide down from the infusion tube due to its own gravity to press down on the Chinese medicine powder at the bottom of the inner tank to avoid the Chinese medicine powder flying everywhere in the inner tank during the mixing process. After the above steps are completed, the staff enters the weighed Chinese medicine powder weight value into the control panel, and then according to the proportion, the control panel controls the metering pump to pump the corresponding volume of glycerin into the inner tank. When the glycerin is pumped, the motor can be driven to rotate so that the stirring paddle stirs and mixes the Chinese medicine powder and glycerin. It should be noted that in the above scheme, because of the pressure of the pressure cover, during the stirring process of the Chinese medicine powder, the space for the Chinese medicine powder is also equivalent to the volume of the Chinese medicine powder in the inner tank, so the possibility of the Chinese medicine powder flying up and adhering to the upper inner wall of the inner tank is also eliminated, so there is no waste of Chinese medicine powder, and the situation of the Chinese medicine powder attached to the inner tank wall being blown into the environment when the sealing cover is opened. When the drug stirring and configuration is completed, and the configured drug needs to be quantitatively taken out externally, the output pump can be started. At this time, the output pump drives the plunger pump to retract, thereby making the discharge channel connected, and the drug is pressed into the discharge channel due to the heavy pressure of the pressure cover. When the drug enters the discharge channel, the quantitative discharge of the drug can be achieved through the output pump.
