DETAILED DESCRIPTION Example 1

[0013] The multifunctional electronic weighing device for weighing traditional Chinese medicine comprises: a receiving tube 1, a weighing box 2, a weighing device 3, a lifting device 5, and a sweeping device 6; the receiving tube 1 is detachably mounted on the side wall of the weighing box 2, and can be replaced at any time through the detachable setting, and the interior of the weighing box 2 is divided into two cavities, namely a lifting chamber 23 and a pushing chamber 24; the lifting device 5 is fixedly mounted on the inner bottom end of the lifting chamber 23, the weighing device 3 is fixedly mounted on the upper end of the lifting device 5, and the sweeping device 6 is fixedly mounted on the inner bottom end of the pushing chamber 24, the vertical position of the weighing device 3 is controlled by the lifting device 5 and the sweeping device 6 is used to push and sweep at the same time; the pushing device can push a rod 67 on the surface of the weighing device 3, and the pushing rod 67 can push out the medicine remaining on the surface of the weighing device 3 after weighing the medicine, so as to ensure the cleanliness of the weighing surface, and then ensure the accuracy of the next weighing time; at the same time, it can also effectively avoid the influence of the residue of the previous medicine on the next medicine.

[0014] The push-sweeping device 6 includes a transmission assembly and a push rod 67; the upper end of the transmission assembly is movably mounted on a vertical rod 66 arranged downwardly in the middle of the push rod 67, and the transmission assembly includes: a transmission rod 60, a support rod 61, a disc 62, a limit block 61, and a rotating rod 63; the support rod 61 is fixedly mounted on the inner bottom end of the ejection chamber 24; the lower end of the side wall of the support rod 61 is respectively and sequentially rotated from bottom to top to connect the disc 62 and the transmission rod 60; the rotating rod 63 is eccentrically mounted on the disc 62, and the limit block 61 is movably mounted on the end of the rotating rod 63, and the limit block 61 is slidably mounted in the key slot provided on the transmission rod 60, and the transmission rod Another limit block 61 is movably installed at the upper end of 60, and the limit block 61 is slidably installed on the vertical rod 66; the transmission rod 60 is controlled by the rotation of the control disk 62 to drive the push rod 67 to move back and forth to achieve scraping of the upper end of the weighing device; a push plate 69 is fixedly installed at the front end of the push rod 67, and a push strip 692 is rotatably installed at the lower end of the push plate 69, and a torsion spring is installed inside the rotating shaft 691; a square groove 11 is provided on one side of the upper end of the inner side wall of the receiving tube 1, and an oblique opening 12 is provided on the side wall corresponding to the square groove 11; the push rod 67 is controlled by the transmission component to move back and forth repeatedly to control the flipping, pushing out and contraction of the push strip 692 to achieve cleaning of the surface of the weighing device 3. Specifically, when working, the motor (not shown in the figure) drives the disc 62 to rotate, and the disc 62 drives the rotating rod 63 to rotate, and after the rotation, the transmission rod 60 is driven to rotate, and the vertical rod 66 movably connected to the upper end of the transmission rod 60 will also move forward and backward (at this time, the rotating rod 63 swings back and forth), thereby driving the sensor to move forward and backward; at the same time, because the rotating rod 63 is eccentrically mounted on the disc 62, the push rod 67 will have the characteristic of rapid return, that is, it is slowly pushed out when moving forward, and is pulled back relatively quickly when returning; In addition, in this embodiment, in order to ensure that the surface of the weighing device 3 can be cleaned well during the push-pull process, the lower end of the push plate 69 is equipped with a push bar 692 through rotation, and a torsion spring (not shown in the figure) is installed inside the rotating shaft 691; a square groove 11 is provided on one side of the upper end of the inner side wall of the receiving tube 1, and an oblique opening 12 is provided on the side wall corresponding to the square groove 11. The oblique opening is set so that when the push bar moves to the position of the end oblique opening 12, due to the inclined surface setting, the push bar 692 will return to its original position under the force of the torsion spring, and will be compressed again when pulled back; this setting can make the push bar 692 completely fit on the weighing device 3 when it is active, and at the same time, the lower end of the push bar 692 is a structure with a wide top and a narrow bottom. Such a setting can make the push bar 692 generate a certain pressure when it rotates, so that it can closely fit the surface of the weighing device 3 for cleaning. At the same time, the weighing device 3 is effectively protected, and the surface of the push bar 692 can include a layer of soft plastic. Example 2

[0015] In this embodiment, based on the lifting device 5 described in Example 1, the lifting device 5 can be set to control the lifting of the weighing device 3, so that the user can weigh the medicine, and it can work with the timer; specifically, the lifting device 5 includes: a first motor 51, a screw 52, ​​and a slider 53; the first motor 51 is fixedly mounted at the bottom end of the lifting chamber 23; the screw 52 is fixedly mounted on the output shaft of the first motor 51; the slider 53 is movably mounted on the screw 52, ​​and a sliding bar 54 is provided on the two side walls of the slider 53, and the sliding bar 54 is slidably mounted on the limit bar 22 provided on the side wall of the lifting chamber 23. The weighing device 3 is fixedly mounted on the upper end of the slider 53, and the sensors 7 are fixedly mounted on the two side walls of the lifting chamber 23 perpendicular to the limit bar 22 and on the slider 53; the control element 4 is fixedly mounted on the upper end of the ejection device. The rise and fall of the slider 53 is controlled by controlling the forward or reverse rotation of the first motor 51, thereby controlling the lifting and lowering of the weighing device 3; when in use, the rotation of the first motor 51 is controlled, and the screw 52 will rotate accordingly, and the rotation of the screw 52 will drive the slider 53 threadedly connected to the screw 52 to move. At the same time, since the sliding bar 54 and the limit bar 22 are slidingly connected on the two side walls of the slider 53, the slider 53 can only move up and down, thereby realizing the lifting function. Example 3

[0016] A system of a multifunctional electronic weighing device for weighing Chinese medicine; specifically comprising sensors 7 installed on both side walls of the lifting chamber 23 and on the slider 53; a control element 4 installed on the ejection device; Sensor 7: used to detect the relative positions. When the positions are parallel to each other, the sensors 7 are fed back to the control element 4, and the control element 4 controls the first motor 51 to stop. There are two sensors 7 in total, one is installed on the side wall of the lifting chamber 23, and the other is installed on the slider 53. Specifically, the sensors 7 are position sensors. When the two sensors 7 are in the same horizontal position, the signals are fed back to the control element 4, and the control element 4 controls the first motor 51 to stop. Control element 4: used to control the operation of the entire device, including the start and stop of the first motor 51, the switch of the weighing device, and the mode switching of the weighing device. The specific mode switching belongs to the prior art and will not be described in detail here (it can be achieved by changing the voltage resistor, or sensors with different precisions are built in for work); the control element 4 includes a timer module, a microprocessor module, a signal receiving module, a display screen 41, and a button 42; the signal receives the signal from the sensor 7 and transmits the signal to the microprocessor module. After receiving the feedback signal, the microprocessor module issues an instruction to control the first motor 51 to stop; then the pushing component performs a pushing operation, and the current working status is displayed on the display screen 41; at the same time, the weighing mode of the weighing device, specifically the range, is switched by the button 42, and the current specific range is displayed on the display; at the same time, the timer starts timing after each push sweep. When the time exceeds the set threshold and the next sweep is performed, it is defaulted that the work is no longer performed. At this time, the microprocessor module controls the first motor 51 to store the weighing device 3 until the button 42 is touched to restore the initial weighing position. The ejection device described in the above process can also be directly used to eject the weighed Chinese medicine, which is convenient for medical staff to quickly configure the medicine. The specific process is: after the system is started, the initialization operation is first performed, including checking the status of each component and setting the initial parameters. After the weighing instruction is input through the button 42, the control element 4 controls the first motor 51 to start and drive the slider 53 and the weighing device 3 to rise. When the sensor detects that the slider 53 is at the same horizontal position as the side wall of the lifting chamber 23, the signal is fed back to the control element 4, and the motor stops running. After the weighing device 3 reaches the predetermined position, the control element 4 starts the weighing device for weighing. The weighing result is displayed to the user in real time through the display screen 41. After the weighing is completed, the control element 4 controls the ejection device to push the Chinese medicine to the specified position. After each weighing operation, the timer starts timing. When the time exceeds the set threshold, the system defaults to no longer work, and the microprocessor module controls the first motor 51 to store the weighing device 3. The user can trigger the operation of restoring the initial weighing position through the button 42.
