Description

Technical Field

[0001] The utility model relates to the technical field of automatic medicine decocting machines, in particular to a leakage-proof liquid submersion structure of an automatic medicine decocting machine. Background Art

[0002] The decoction machine is a decoction device that can decoct medicine quickly. Chinese herbal decoction is one of the traditional dosage forms of Chinese medicine. The quality of the decoction directly affects the clinical efficacy. The material basis for the decoction to affect the efficacy is mainly the effective ingredients decocted in the decoction. Therefore, in order to exert the clinical efficacy of Chinese herbal decoction, it is necessary to decoct the effective ingredients to the maximum extent possible.

[0003] For example, China Utility Model Patent Publication No. (CN205272651 U) discloses an automatic medicine pressing structure of an automatic medicine decocting machine, which includes a pot body, a pot cover and a medicine residue extrusion mechanism. The pot body is sealed with a pot cover, and the pot cover is coaxially mounted with the medicine residue extrusion mechanism. The medicine residue extrusion mechanism includes a vertical pipe, a screw, a screw nut and an extrusion plate. The vertical pipe is vertically mounted on the top of the pot cover, and the screw is coaxially mounted inside the vertical pipe. The outside of the screw is coaxially meshed and connected in the screw nut. A connecting pipe is coaxially mounted downward on the outside of the screw nut, and an extrusion plate is mounted at the lower part of the connecting pipe. The screw nut is driven by the rotation of the screw. The patent discloses a patent patent for a patent in which a motor is installed on the top side of the lead screw to move up and down, and a motor is installed on the top side of the lead screw, and the motor drives the lead screw to rotate through a belt drive. This practical solution solves the problem that the manual driving of the extrusion disk not only occupies manpower, but also has low work efficiency, and the pressure of the extrusion disk depends entirely on the operator's intuition, which affects the separation effect of the liquid medicine. However, the patent discloses an invention that extrudes from top to bottom, and the structural components used for extrusion are accumulated on the pot cover, resulting in a large gravity that the pot cover needs to withstand when opening the automatic decoction machine. This makes it not only inconvenient to open, but also easy to collide with the surroundings, affecting practicality. Utility Model Content

[0012] Furthermore, the number of the position sensors is two, and they are symmetrically distributed up and down about the central axis of the guide rod.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. The anti-leakage liquid submersible extrusion structure of the automatic medicine decoction machine can drive the driving gear to rotate through the cooperation of the motor, thereby driving the driven gear and the screw to rotate.

A first flange seat 4 is fixed on the lower surface of the medicine decocting barrel 1, and a second flange seat 5 is fixed on the upper surface of the mounting box 2. A limiting mechanism 6 for controlling the squeezing range is provided on the medicine decocting barrel 1 to prevent the cover plate of the medicine decocting barrel 1 from being deformed or damaged due to excessive force, and a discharge pipe 7 is connected to the lower surface of the medicine decocting barrel 1.

[0023] Among them, the outer side of the medicine decoction barrel 1 is hinged with a barrel cover 8 through a hinge shaft, the outer side of the barrel cover 8 is fixed with a locking ring 9, and the outer side of the medicine decoction barrel 1 is fixed with a lock buckle 10, which is convenient for closing and fixing the medicine decoction barrel 1 and improving the sealing performance of the medicine decoction barrel 1.

[0024] See also Figure 2-3 In order to reduce the space occupied by the medicine decoction machine and prevent the leakage and waste of medicine liquid during squeezing, the squeezing mechanism 3 in this embodiment includes a motor 301, which is fixed to the right side of the installation box 2, and the output shaft of the motor 301 penetrates and extends to the inside of the installation box 2, and is fixed with a driving gear 302, the output shaft of the motor 301 drives the driving gear 302 to rotate, the outer side of the driving gear 302 is meshed with a driven gear 303, the driving gear 302 drives the driven gear 303 to rotate, the driven gear 303 is rotatably connected to the inner bottom wall of the installation box 2 through a bearing, a screw rod 304 is fixed to the inner side of the driven gear 303, the driven gear 303 drives the screw rod 304 to rotate, the other end of the screw rod 304 penetrates the installation box 2 and extends to the upper side of the second flange seat 5, and the outer side is threadedly connected with a threaded sleeve 305, the screw rod 304 drives the threaded sleeve 305 to move The top of the threaded sleeve 305 passes through the first flange seat 4 and extends to the interior of the medicine decoction barrel 1, and is fixed with an extrusion plate 306. The threaded sleeve 305 drives the extrusion plate 306 to move, squeezes the medicine bag and the barrel cover 8, and allows the medicine liquid to flow out fully. A guide rod 307 is fixed between the upper surface of the second flange seat 5 and the first flange seat 4. A connecting plate 308 is fixed to the outer side of the threaded sleeve 305. A slider 309 is fixed to the upper surface of the connecting plate 308. The inner side of the slider 309 is slidably connected to the outer side of the guide rod 307. When the threaded sleeve 305 moves, the connecting plate 308 is driven to move. The connecting plate 308 drives the slider 309 to move. The slider 309 slides on the guide rod 307. The guide rod 307 limits the connecting plate 308 and the threaded sleeve 305 to avoid angle deviation. A liquid leakage prevention component is provided on the connecting plate 308.

[0025] In this example, there are two guide rods 307 , which are symmetrically distributed about the central axis of the first flange seat 4 , so that the connecting plate 308 can maintain balance and stability during the movement.

[0026] It should be noted that the anti-leakage component includes a guide plate 310, which is fixed to the upper surface of the connecting plate 308. A sealing ring 311 is fixed to the inner side of the first flange seat 4. During the movement of the threaded sleeve 305, the sealing ring 311 seals the first flange seat 4 as much as possible. However, it is inevitable that a small amount of liquid medicine will leak. The leaked liquid medicine flows down along the threaded sleeve 305 and flows to the guide plate 310. A collection box 312 is provided below the guide plate 310. The guide plate 310 guides the liquid medicine to the collection box 312. 12 to avoid wasting of liquid medicine, a hanging ring 313 is fixed to the outside of the collecting box 312, a card slot 314 is opened on the upper surface of the guide plate 310, and the hanging ring 313 is located inside the card slot 314, so that the collecting box 312 can be easily removed from the guide plate 310, and the collecting box 312 can move synchronously with the guide plate 310, the inner diameter of the sealing ring 311 is adapted to the outer diameter of the threaded sleeve 305, and the outer diameter of the hanging ring 313 is adapted to the width of the card slot 314, so as to prevent the position of the collecting box 312 from shifting forward and backward.

[0027] See also Figure 4 In order to prevent the cover plate of the medicine decoction barrel 1 from being deformed or damaged due to excessive force, the limiting mechanism 6 in this embodiment includes a support plate 601, which is fixed to the lower surface of the medicine decoction barrel 1, and a position sensor 602 is fixed on the front of the support plate 601. An inductor 603 is fixed on the right side of the connecting plate 308. When the connecting plate 308 moves, the inductor 603 is driven to move. When the inductor 603 moves to the position sensor 602, the position sensor 602 and the inductor 603 are inductively sensed, and then the position sensor 602 sends a stop signal to the motor 301 to stop the threaded sleeve 305 from moving, thereby limiting the moving range of the threaded sleeve 305 to prevent the barrel cover 8 from being deformed or damaged due to excessive force.

[0028] In this example, there are two position sensors 602 , which are symmetrically distributed up and down about the central axis of the guide rod 307 , so that the connecting plate 308 can be limited when moving upward or downward.

[0029] The working principle of the above embodiment is:

[0030] (1) First, open the barrel cover 8, put the medicine bag into the medicine decoction barrel 1, and pour an equal proportion of water into the medicine decoction barrel 1, then close the barrel cover 8 and lock the lock ring 9 and the lock buckle 10, then heat the medicine decoction barrel 1 to decoct the medicine, and after the decoction is completed, open the discharge pipe 7, and the medicine liquid flows out from the discharge pipe 7. At this time, the medicine bag is still full of medicine liquid, and it is necessary to squeeze the medicine bag to avoid wasting the medicine liquid. Turn on the motor 301, and the output shaft of the motor 301 drives the driving gear 302 to rotate, the driving gear 302 drives the driven gear 303 to rotate, the driven gear 303 drives the screw rod 304 to rotate, the screw rod 304 drives the threaded sleeve 305 to move, and the threaded sleeve 305 drives the extrusion disk 306 to move, squeeze the medicine bag and the barrel cover 8, so that the medicine liquid can flow out fully.

[0031] (2) When the threaded sleeve 305 moves, the connecting plate 308 is driven to move, and the connecting plate 308 drives the slider 309 to move. The slider 309 slides on the guide rod 307. The guide rod 307 limits the connecting plate 308 and the threaded sleeve 305 to avoid the angle from being offset. During the movement of the threaded sleeve 305, the sealing ring 311 seals the first flange seat 4 as much as possible. However, it is inevitable that a small amount of liquid medicine will leak. The leaked liquid medicine flows down along the threaded sleeve 305 and flows to the guide plate 311. At 10, the guide plate 310 guides the medicine liquid to the collection box 312 for collection to avoid waste of the medicine liquid. When the connecting plate 308 moves, the sensor 603 is driven to move. When the sensor 603 moves to the position sensor 602, the position sensor 602 and the sensor 603 are inductively sensed, and then the position sensor 602 sends a stop signal to the motor 301 to stop the threaded sleeve 305 from moving, thereby limiting the movement range of the threaded sleeve 305 to prevent the barrel cover 8 from being subjected to excessive force and being deformed or damaged.
