Description

Technical Field

[0001] The present invention relates to the field of pharmaceutical machinery and equipment, and particularly to an integrated decocting and brewing machine. Background Art

[0002] For common household medicines, the use of traditional Chinese medicines and Western medicines is essential. Among Western medicines, brewing medicines is common and necessary. However, for most people, the method of brewing medicines is to place the medicines in a cup and then pour boiling water, and at most use chopsticks or other items to stir and dissolve them. Little time is really spent on truly paying attention to elements such as the temperature, water volume, and medicine dosage required for brewing medicines. But sometimes such small oversights can cause the efficacy of certain medicines to be greatly reduced or even lost, resulting in the patient's condition not improving fully and effectively. In addition, the decocting and brewing of traditional Chinese medicines often require manual control of the heat, decocting time, first decoction and second decoction of traditional Chinese medicines, etc. If the patient decocts by themselves, it may cause the traditional Chinese medicine not to exert its full effect, and there are also certain risks. Summary of the Invention

[0003] The purpose of this case is to provide an integrated decocting and brewing machine to achieve automatic brewing of medicaments and automatic decocting of traditional Chinese medicines, facilitating drug services. To achieve the above purpose, the technical solutions of this case are as follows.

[0004] An integrated decocting and brewing machine includes a medicine machine housing (22), a medicine bag bin, a pushing mechanism, a bag-opening mechanism, a stirring mechanism, a traditional Chinese medicine decocting mechanism, and a water tank (45). The water tank (45) is divided into upper and lower layers, with cold water in the upper layer and hot water in the lower layer. The medicine machine housing (22) has a middle layer plate. The pushing mechanism, the bag-opening mechanism, the stirring mechanism, the traditional Chinese medicine decocting mechanism, and the water tank (45) are all fixed on the middle layer plate. There are holes on the middle layer plate, through which the stirring head (15) of the stirring mechanism can telescopically pass, and the hot water pipe of the water tank (45), the liquid medicine outlet pipe of the traditional Chinese medicine decocting mechanism, and the medicine leakage pipe of the bag-opening mechanism all pass through the middle layer plate. A turntable base (50) is installed at the bottom of the medicine machine housing (22). There is a support column-shaped shell (49) in the middle of the turntable base (50) to support the middle layer plate. There is also a cup holder (52) for placing cups on the turntable base (50). The turntable base (50) is configured to rotate around its central axis, thereby driving the cups on the cup holder (52) to rotate.

[0005] In this technical solution:

[0006] When the integrated decocting and brewing machine is in use, the cup is configured to stay at the position where it needs to stay for a set time and then rotate again, while enabling the pushing mechanism, the bag-opening mechanism, the water supply and heating of the water tank, and the stirring mechanism to cooperate successively to complete the brewing of medicaments or the decocting of traditional Chinese medicines.

[0007] Advantageous technical effects of this case: It can automatically brew medicine according to the dosage of medicine, the required temperature of medicine, and the amount of water; it can automatically control the water volume for decocting according to the formula and decocting requirements of traditional Chinese medicine, facilitating drug service.

Specific implementation mode

[0036] Refer to Figure 1-1 7

[0037] Refer to Figure 1 、 Figure 2, the medicine machine housing (22) is the main support of the machine. Its interior is a double-layer cavity structure. There is a middle layer board between the upper and lower cavities. Two groups of exhaust fans (35) are installed at the front position of the upper cavity. In addition to the exhaust fans (35), a medicine cutting system, a traditional Chinese medicine system, a stirring system, a water tank and other main mechanism modules are also installed in the upper cavity of the medicine machine housing (22). A turntable system is installed in the lower cavity of the medicine machine housing (22). The arc-shaped perspective window (29) is embedded in the front part of the lower cavity of the medicine machine housing (22) through three card slots on each of the left and right sides.

[0038] The upper part of the medicine machine housing (22) is equipped with a medicine machine upper cover (3) and a decocting pot upper cover (28). The decocting pot upper cover (28) is buckled in the center of the medicine machine upper cover (3) and can be opened. Three air outlet nets (39) are fixed to the upper part of the medicine machine upper cover (3). Two rectangular air inlet nets (34) are attached to the front part of the medicine machine housing (22). In the ventilation system of this machine, external air enters from the air inlet net (34), passes through the exhaust fan (35), and then is discharged through the air outlet net (39). The medicine box cover (7) is buckled on the upper part of the medicine machine upper cover (3). The cavity formed by the medicine box cover (7) and the medicine machine upper cover (3) contains the medicine bags to be brewed.

[0039] The rear part of the medicine machine housing (22) is equipped with a medicine machine rear cover (23). A pull-out trash box (40) is installed on the medicine machine rear cover (23). The trash box (40) is used to collect the discarded medicine packaging bags.

[0040] The lower pull-out tray (24) is movably installed in the card slot at the lower part of the medicine machine housing (22) and can be pulled out. Its main purpose is to catch the medicine powder, liquid, etc. that spill outside the medicine cup, which is convenient for cleaning.

[0041] As Figure 3 、 Figure 4 shown in the overall schematic diagram of the medicine discharging system and the partial enlarged schematic diagram of the lead screw push rod of the medicine discharging system. The lead screw (2) is the core part of this structure. It is fixed to the medicine machine upper cover (3) by two lead screw fixing parts (1, 13). The lead screw is fixedly connected with the push rod pinion (8) and rotates synchronously. The output end of the stepping motor (14) is a gear structure, which meshes with the driving large gear (9), and the driving large gear (9) meshes with the push rod pinion (8), so as to transmit the rotation of the lead screw stepping motor to the rotation of the lead screw (2).

[0042] There is a transmission thread on the lead screw (2), which cooperates with the medicine pushing plate (10). As the lead screw (2) rotates, the medicine pushing plate (10) will slide left and right along the lead screw guide to realize the pushing function of the medicine bag (11). The part extending from the rear of the medicine pushing plate (10) is used to receive and push the medicine bag.

[0043] The rear part of the upper cover (3) of the medicine machine is the rear bin, which consists of three medicine boxes. Different types of granule medicines can be placed together. Each medicine box has a rectangular window on the front-facing part, and there is a liftable medicine lifting plate (4) at the bottom of each medicine box. A number of medicine packets (11) are placed on it. When the medicine lifting plate (10) is installed, it has a certain forward inclination. As the medicine lifting plate rises, the medicine packets will slide out of the window of the medicine box one by one and fall onto the medicine pushing plate (10). The middle and rear part of the upper cover (3) of the medicine machine is the middle bin. The lead screw push rod mechanism is installed in the middle bin of the upper cover of the medicine machine through lead screw fixing parts (1)(13).

[0044] Lifting the medicine lifting plate (4) corresponding to the medicine box causes a bag of medicine to slide out. A button can be set in front of the medicine box and controlled through the button, or it can be controlled through an APP according to the user's choice of medicine using a program.

[0045] As Figure 5 shown, there is an opening at the bottom right of the middle bin of the upper cover (3) of the medicine machine. The size of the opening is larger than the length and width of the medicine packet. When the medicine packet is pushed to the rightmost state, the medicine packet can leak through this opening to the following medicine cutting mechanism below.

[0046] The structural schematic diagram of the medicine cutting mechanism is as Figures 6-8 shown. It mainly uses a lead screw (transmission screw) and rocker drive, which has the characteristics of being convenient, precise, and easy to be driven by a motor. The scissors mechanism is driven by a servo motor. The lower blade is fixedly connected to the scissors frame body and remains stationary. The upper blade realizes reciprocating swing through the repeated action of cam drive and an internal torsion spring, with high transmission efficiency, meeting the force required for opening the medicine bag.

[0047] As Figure 6 shown, the bottom of the cam scissors lower bracket (87) is installed on the outer shell (22) of the medicine machine through bolts (94) and washers (95). The medicine leakage hopper (96) is installed in cooperation with it through the groove structure on the outer shell (22) of the medicine machine. The medicine leakage pipe structure of the medicine leakage hopper (96) passes through the middle layer plate of the outer shell of the medicine machine during installation, so that the medicine powder in it can fall into the medicine cup (52) below. The outer shell (22) of the medicine machine and the upper cover (3) of the medicine machine are detachably installed and are divided into upper and lower cavity structures by the middle layer plate.

[0048] As Figure 7 shown, the first jaw link (75) is installed on the medicine leakage hopper (96) through the jaw link fixing pin (85). The link bearing (91) ensures that the first jaw link (75) can rotate around the fixing pin (85). The other end of the first jaw link (75) has a protruding pin, which cooperates with the second jaw link (76), enabling the second jaw link to rotate around one end of the first jaw link. The other end of the second jaw link is cooperated with the jaw cross bar (77) through the second link fixing pin (92).

[0049] There is a groove-shaped protrusion in the middle of the jaw cross bar (77), which cooperates with the long groove on the medicine leakage hopper (96), enabling the jaw cross bar to only move vertically up and down. When the first jaw link (75) rotates around the jaw link fixing pin (85), the jaw cross bar is driven to move up and down through the second jaw link.

[0050] Two pairs of jaws are rigidly installed on the jaw cross bar (77). Each pair of jaws consists of a jaw frame (70), an upper jaw finger (71), a lower jaw finger (72), a jaw servo (73), and a servo gear (74). Among them, the gear parts of the upper jaw finger (71), the lower jaw finger (72), and the servo gear (74) mesh and drive each other. The output end of the servo (73) is fixedly connected to the servo gear (74). When the output end of the servo rotates, the servo gear rotates synchronously, and the upper and lower jaw fingers close or open, thereby clamping or releasing the medicine bag. In particular, the contact ends of the upper and lower jaw fingers are designed to be inclined, so that the medicine bag is inclined when clamped, which is conducive to the powder spilling.

[0051] As Figure 8 shown, the upper scissor blade (78) and the lower scissor blade (79) are respectively connected to the scissor frame (97) through the upper blade (79) fixing pin (81) and the lower blade fixing pin (84). Among them, the upper scissor blade (79) can rotate around the fixing pin (81). The cam servo (82) is fixedly installed on the scissor frame (97). The output end of the servo is an eccentric cam, which contacts the lower end surface at the rear of the upper scissor blade (79). As the cam servo rotates, the upper scissor blade (79) will synchronously rotate within a certain inclination range, realizing the feeding translation of the scissors, making the cutting of the medicine bag more complete. The two scissor blades in the medicine cutting mechanism have two actions: "opening" (referring to an increase in the opening angle) and "closing" (referring to a decrease in the opening angle), which respectively correspond to the two processes of the cam turning from the thin part to the thick part and then from the thick part to the thin part. The "opening" action is realized by the motor driving the cam to rotate, and the cam pushes the upper blade upward. The "closing" action is realized by the deformation and rebound of the torsion spring. The spring coil of the torsion spring is sleeved on the fixing pin (81), and the two end fixing parts are respectively located in the grooves of the upper scissor blade (78) and the lower scissor blade (79). When the opening angle of the scissors becomes larger, the spring will be twisted, so a rebounding force is generated, making the scissor blades always contact the cam surface.

[0052] As Figure 9 shown, the scissor frame (97) is installed on the cam scissor rear cover (86) through four bolts (94) and washers (95). A cam scissor gear (90) is installed at the lower part of the cam scissor rear cover (86). This gear meshes with the lower cam scissor rack (89). The cam scissor rack (89) is fixedly installed on the cam scissor lower frame (87). When the cam scissor gear (90) rotates, it will drive the upper scissor mechanism to move back and forth along the rack guide direction.

[0053] As Figure 10 , Figure 11 , Figure 12 shown, two stirring lifting racks (20) are respectively installed on the front rack machine (19) and the rear rack machine frame (21). The bottoms of the front rack machine (19) and the rear rack machine frame (21) are fixedly connected to the medicine machine housing (22). The large transmission gear (12), the rack pinions (181)(183), the small transmission gear (18-2), and the stirrer motor (16) are all installed on the stirrer housing (17). The large transmission gear (12) meshes with the rack pinions (18-1) and the small transmission gear (18-2). The small transmission gear (18-2) meshes with the rack pinion (183). The rack pinions (181)(183) respectively mesh with the two stirring lifting racks (20). When the large transmission gear (12) rotates, it drives the rack pinions (181)(183) to rotate simultaneously, so that the stirrer housing (17) vertically lifts and lowers along the direction of the rack guide. The stirring head (15) is connected to the output end of the stirrer motor (16). When the output end of the stirrer motor (16) rotates, the stirring head (15) rotates synchronously to stir the mixture of drug particles and water, accelerating the dissolution of the drug particles. Note: The rack pinions and the 182 transmission pinions 181, 183 adopt gears with the same model parameters (the same number of teeth and module).

[0054] As Figure 13 , Figure 14 shown, the stepping motor (14) is fixedly installed on the turntable base (50). The upper layer turntable (53) is composed of 6 mesh plates. Each mesh plate is fixedly installed on the turntable bottom frame (50) through a card slot. The turntable bottom frame (50) is installed at the bottom of the medicine machine housing (22). A support columnar shell (49) is fixedly installed in the center of the turntable bottom frame (50). The support columnar shell (49) is a hollow shell structure, which plays the role of protecting the internal mechanism and supporting the middle layer plate of the medicine machine housing (22). The cup holder (52) is movably installed on the turntable base (50) and can move back and forth along the guide groove on the turntable bottom frame (50). A medicine cup can be placed in the cup holder (52). The turntable bottom frame (50) as a whole can rotate around its central axis, driving the mechanisms such as the cup holder (52) on it to rotate, so that the medicine cup can move to each required position to receive liquid medicine, medicine powder, water, etc.

[0055] As Figure 15As shown in the figure, the rear end of the cup holder (52) is fixedly connected to the cup holder bayonet (57), the rear end of the cup holder bayonet (57) is connected to the telescopic mechanism connecting piece (56), and the rear end of the telescopic mechanism connecting piece (56) is matched with the front end of the parallelogram telescopic mechanism (58). The output end of the stepping motor (14) is connected to the synchronous belt pulley (67). The synchronous belt pulley (67) on the stepping motor (14) meshes with the synchronous belt (68). The synchronous belt pulley at the other end of the synchronous belt (68) is located on the upper part of the parallelogram telescopic mechanism (58) and is connected to the parallelogram link frame (58-1). The parallelogram link frame (58-1) can contract or expand on the rod (58-2). When the output end of the stepping motor (14) rotates, the parallelogram telescopic mechanism (58) is driven to contract or expand through the synchronous belt drive, so as to realize the forward and backward movement of the cup holder (52) along the guide groove of the turntable chassis (50). A partitioned filter screen is arranged on the turntable chassis (50), and a snap-in partition design is adopted to avoid the risk of water accumulation and facilitate disassembly and cleaning. In particular, when the cup is selected to the position where it needs to be telescoped, it is locked, the cup is pushed out or pulled in, and then the turntable rotates and unlocks automatically.

[0056] Figure 16 It is the overall diagram of the traditional Chinese medicine system. The decocting pot rack (41), the water tank (45), and the medicine storage pot (46) are all directly fixedly installed on the middle layer board of the medicine machine housing (22). The position of the medicine storage pot (46) is lower than that of the decocting pot (42). The decocting pot (42) is installed on the upper part of the decocting pot rack (41). There is an inner filter screen (43) inside the decocting pot (42) to separate the traditional Chinese medicine from the medicinal liquid. An openable upper cover (28) of the decocting pot is installed on the upper part of the decocting pot (42). The water outlet pipe (44) is used to connect the decocting pot (42) and the water tank (45). The water pump (48) is installed in the middle of the water outlet pipe (44) to pump the water in the water tank (45) into the decocting pot (42). The medicine outlet pipe (47) connects the medicine storage pot (46) and the decocting pot (42). When the first decoction or the second decoction of the traditional Chinese medicine is completed, the valve inside the medicine outlet pipe (47) opens, and the decocted traditional Chinese medicine flows from the decocting pot (42) into the medicine storage pot (46) for heat preservation storage to facilitate the user to take the medicine and better exert the characteristics of the traditional Chinese medicine.

[0057] In particular, the water tank (45) is divided into upper and lower layers. The upper layer is the cold water layer with a larger space, and the lower layer is the hot water layer with a heating pipe, a water quantity sensor (composed of devices such as a magnet, a float, and a reed switch), and a water temperature sensor. There is a separation plate made of heat insulation material between the upper and lower water tanks. A first electric water valve is installed on the separation plate. When the electric water valve is opened, water flows from the upper water tank into the lower water tank. There are two water outlets of the water tank, which are located at the upper and lower parts of the water tank respectively ( Figure 16As shown. The water outlet at the upper part is connected to the upper water tank and is equipped with a water pump. This water outlet is used to quantitatively discharge cold water, which flows into the decocting pot (42) for decocting medicine. The water outlet at the lower part is connected to the lower water tank, and a pipe is led vertically downward (see Figure 16 ), and a second electric water valve is installed in the pipe. This water outlet is used to discharge hot water at a constant temperature and in a fixed quantity for flushing medicine. Its working process is as follows: When the control system receives the instruction to discharge water for soaking medicine, it first opens the first electric water valve located on the separation plate, and water flows from the upper water tank into the lower water tank. Through the feedback of the water quantity sensor in the lower water tank (when the required water level is reached, the water level sensor will send a signal to close the first electric water valve), a fixed quantity of cold water is injected into the lower water tank. Then, the heating pipe in the lower water tank starts to heat. When the required water temperature is reached, the water temperature sensor sends a signal, and the heating pipe stops heating. The second electric water valve is opened, and water is discharged downward, and a fixed quantity of hot water is put into the cup below.

[0058] The hot water layer is controlled to heat by electronic components. The hot water layer and the medicine discharging pot can control the heat preservation temperature.

[0059] For an example of the operation circuit of the medicine decocting and soaking integrated machine, see Figures 17-1 to 25 .

[0060] The electric control system of the medicine decocting and soaking integrated machine includes a total control system (see Figure 17-1 , Figure 17-2 ), a transmission system control system (see Figure 18 ), a medicine pushing rod control system (see Figure 19 ), a medicine clamping and shearing control system (see Figure 20 ), a water level control system (see Figure 21 ), a heating control system (see Figure 22 ), a medicine packaging and cleaning control circuit (see Figure 23 ), a stirring control circuit (see Figure 24 ), and a traditional Chinese medicine decocting control circuit (see Figure 25 ).

[0061] The working process of soaking medicine of the medicine decocting and soaking integrated machine is as follows.

[0062] When the turntable chassis (50) moves to the corresponding position, place the cup at the corresponding position on the conveyor belt. See Figure 17- Figure 18, press the switch S1, and the transport turntable drives the cup to move. When the cup moves to the first specified position, since the travel switch S2 is pressed, the "+" input of the comparator is at a high level, the input is 1, the output is at a high level, the output is 1, the energizing time relay KT1 and the de-energizing time relay KT4 work. The normally closed contact of KT1 delays to open, and its function is to delay based on the first action to ensure that this action can be fully completed. The instantaneous break contact (normally closed contact) of KT1 opens, the transport turntable stops running, and the first step begins, that is, the drug packaging cutting work.

[0063] When the cup runs to the first travel switch S2, since S2 is pressed, the delayed closing contact of the KT4 time relay closes. Since it is a de-energizing time relay, it will close after a delay after de-energization. After a certain delay, the normally closed contact of the KT1 time relay opens, and the V1 comparator outputs a low level again, the output is 0, KT1 and KT4 are de-energized, the instantaneous closing contact of KT1 closes, and it returns to the operating state of the transport turntable, and other parts are fully reset.

[0064] For the next process, see Figure 19 Figure 20 , the system operation during this period: when the normally open contact of the KT4 de-energizing delay closes, the M8 push rod motor rotates forward, and the push rod pushes the medicine bag to the clip, making the normally closed travel switch S12 close, and the circuit is disconnected. When S12 is disconnected, the V8 comparator outputs a high level, enabling the K2 ordinary relay, making its normally open contact close. When the normally open contact of the KT1 energizing delay closes, the motor M9 rotates forward to clamp the medicine bag, and the current cut-off electric time relay KT7 starts to work, and the push rod working circuit also starts to work. The M2 motor is the driving motor of the cutting system. The whole process continuously performs periodic motion to cut the drug packaging. Through the instantaneous closing of the instantaneous normally open contact of the KT7 time relay, the M3 motor is controlled to rotate forward, and the normally open contact of the KT7 delay closes, making the push rod send the medicine bag to the specified position, making the S5 travel switch disconnect, and the medicine clamping and shearing control circuit starts to work, and the motor M3 that controls the advancement of the cutting mechanism stops moving. The shearing mechanism cuts open the medicine bag, pours the medicine into the cup, the medicine packaging falls into the trash can behind the slope, and the medicine falls into the lower funnel. After a certain delay, the normally closed contact of the KT13 power-off electromagnetic relay returns to the initial state, that is, it closes, and the normally open contact remains disconnected, making the relay circuit self-lock, and the motor of the control circuit of the cutting mechanism rotates in reverse, and the mechanism retracts. Subsequently, the push rod returns to its position, the clip opens, the KT1 contact disconnects, and the medicine clamping and shearing control circuit stops working. Since the normally closed contact of KT4 closes, the push rod motor rotates in reverse and resets. When it touches the S13 travel switch, the motor stops working, and the push rod reset is completed, and the transport mechanism starts to work again, sending the cup filled with drug powder to the next process.

[0065] Similarly, when the cup reaches the second travel switch S3, the conveying device stops working and starts the heating and water supply operations. For the subsequent processes, refer to Figures 21-22 , the heating operation can be selectively run. If normal temperature water is needed, there is no need to touch the heating switch button S11 and the heating system will not work. If the warm water, hot water, or boiling water button is touched, this system will start working. When the temperature is lower than the lower limit temperature, the V6 voltage comparator outputs 0, 0, the 3rd pin of NE555 outputs a high level, and the E2 heating wire starts to heat. When heating from the lower limit temperature to the upper limit temperature, the V5 comparator outputs 0, the V6 comparator outputs 1, NE555 maintains the previous working state, emits a high level, that is, 1, and the heating wire continues to heat. When the temperature reaches or exceeds the upper limit temperature, V5 outputs 1, V6 outputs 1, the 3rd pin of NE555 outputs a low level, that is, 0, and the E2 heating wire stops working. When heating from the upper limit temperature to the lower limit temperature, V5 outputs 0, V6 outputs 1, NE555 maintains the previous working state, outputs a low level, and the heating wire remains in the dormant state until the lower limit temperature. This process repeats to achieve the heating and heat preservation control within the temperature range. At the same time, there is also a medicine packaging cleaning control system, which is designed separately. For details, please refer to Figure 23 , when the sensor detects the remains of the medicine package, the motor rotates forward, and the control can lower the rotatable funnel plate to make the medicine package slide into the trash can. Subsequently, the motor rotates backward and the funnel plate resets, completing one cleaning of the medicine package. At the same time, the main mechanisms operate independently without affecting each other.

[0066] Similarly, when the cup reaches the third travel switch S4, the conveyor belt stops working and starts the stirring operation. For the subsequent processes, refer to Figure 23, when the travel switch of the transport turntable control system is pressed, the “+” terminal of V3 inputs a high level and outputs a high level. KT3 and KT6 start to work, and the stirring control system is activated. Since the stirring head is controlled by KT6, it keeps working during the operation of this system. The initial state of the up and down movement mechanism is that K1 inputs current, making its normally closed contact disconnect and its normally open contact close. KT8 energizes and the electromagnetic relay does not work. The contact of KT8 disconnects, causing the motor M5 to rotate forward and the stirring head to move downward. The M6 motor is the driving motor of the stirring fan blade and rotates to stir during the whole movement of the entire device. The M5 motor is the motor that controls the up and down movement of the stirring device. In this case, this motor rotates forward and the device moves downward for stirring. When the device descends to a certain position, it touches the S6 travel switch, causing it to disconnect. The normally closed contact of K1 closes due to the power-off of the relay, making the VD6 power-on time relay energize and start to work. At the same time, the fan blade control motor still continues to work. After a delay of a period of time, that is, after waiting for the medicine to be fully stirred, the normally open contact of the KT8 power-on delay closes, causing the motor to rotate in reverse and move upward. The function of KT14 is to make the mechanism run reliably when the mechanism moves upward. When it moves upward to the initial position, it touches the travel switch S7 and KT8 de-energizes. When the time of KT3 and KT6 arrives, the relay is triggered by delay and relevant actions are executed. The transport turntable restarts to work and transfers the cup filled with brewed medicine, thus completing the whole medicine brewing process.

[0067] The decocting work process of the integrated medicine decocting and brewing machine is as follows: Place traditional Chinese medicine inside the filter screen of the decocting pot, start decocting after injecting water. After the decocting is completed, the medicine flows into the traditional Chinese medicine pre-storage box for heat preservation. Then, water is injected again to start the second decocting. After each decocting is completed, the medicine flows into the traditional Chinese medicine storage pot. After the decocting steps are completed, the lower valve of the traditional Chinese medicine storage pot is opened to make the traditional Chinese medicine flow into the medicine cup. For details of the circuit diagram, please see Figure 25 。

[0068] Example of the dimension interval design of relevant mechanisms of a medicine decocting and soaking integrated machine. By statistically analyzing the length and width dimensions of medicines, the length range of the medicine bags of most soaking medicines is 80 - 100 mm, and the width range is 50 - 70 mm. Based on this, the important dimensions and intervals of mechanisms such as the medicine box, scissors, and clamping jaws are designed to ensure the smooth opening of medicines. According to "a decoction of traditional Chinese medicine is taken orally in 2 - 3 times, 100 - 200 ml each time"; the water volume for soaking medicine: "150 - 200 ml"; and the dimensions and intervals of relevant mechanisms for decocting traditional Chinese medicine are designed accordingly. Specifically, the medicine warehouse is composed of three medicine boxes with different lengths, which can accommodate different medicines. The internal length is 120 - 130 mm, and the width is 90 mm. The effective blade length of the electric scissors: 70 mm; the movable length of the scissors: 110 mm. The vertical movement height of the clamping jaws: 85 mm. The maximum diameter of the stirring head: 40 mm; the vertical movement height: 180 mm. The inner diameter of the traditional Chinese medicine decocting and soaking pot is 160 mm; the height is 130 mm. The arc radius of the left end face of the traditional Chinese medicine storage box is 115 mm; the arc radius of the right end face is 230 mm; the height is 130 mm. The height of the total water tank is 235 mm; the length (inside) is 160 mm; the width (inside) is 140 mm; the arc radius of the right end face is 100.

[0069] The decocting and soaking integrated machine can have a corresponding APP human - machine interaction interface, and various operations can be completed on the mobile phone. Specifically, on the APP page, there are selection buttons "granules" and "traditional Chinese medicine". If "granules" is selected, for the type without stored {temperature, water volume}, manually input the temperature and water volume required by the type. When the input is completed, this type of data is stored locally or uploaded to the cloud for storage, and the storage name can be set by oneself. For the type with stored {temperature, water volume}, the decocting and soaking integrated machine starts to work. After the work is completed, the user takes the medicine. If "traditional Chinese medicine" is selected, it further prompts "select a prescription". For those with a doctor's prescription or pre - made prescription, the decocting and soaking integrated machine starts to work. After the work is completed, the user takes the medicine. For those without a prescription, the user manually inputs the prescription, the preservation temperature, the decocting time, and whether secondary decocting is required. When the input is completed, the data is stored locally or uploaded to the cloud for storage, and the storage name can be set by oneself.
