Technical Field

[0001] This utility model relates to the technical field of traditional Chinese medicine decoction devices, and in particular to a decoction machine. Background Technology

[0002] As a core piece of equipment for modern Chinese medicine decoction, the decoction machine is widely used in medical institutions, pharmacies, and homes. The main structure of the decoction machine is a sealable container. During use, water and a bag containing the medicinal herbs are placed inside and sealed. Heating is then achieved through electricity or magnetism to decoct the herbs. However, during decoction, the bag of herbs floats on the surface, preventing the herbs from being fully submerged. Furthermore, the sealed decoction process makes it difficult to stir and compress the herbs, affecting the quality of the decoction. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a decoction machine with a simple structure, easy operation, and the ability to squeeze the dregs bag.

[0004] To solve the above-mentioned technical problems, this utility model provides a decoction machine, including a cylinder body, a cylinder cover, a pressing connecting rod, and a pressing disc. The bottom of the cylinder body is provided with a heating disc. The cylinder cover is closable and covers the top of the cylinder body. The top of the cylinder cover is provided with a through hole communicating with the interior of the cylinder body. The pressing rod is slidably engaged with the through hole. The pressing rod includes a connecting pipe, a sliding rod, a spring, and a connecting rod. A sleeve is fixed to the bottom end of the connecting pipe. The diameter of the sleeve is smaller than the diameter of the connecting pipe. The sliding rod passes through the connecting pipe and is slidably connected to the sleeve. The top end of the sliding rod is provided with a limiting flange. The spring is sleeved on the sliding rod and located between the top end of the sleeve and the bottom end of the limiting flange. The top end of the connecting rod is provided with a connecting shaft. The top end of the connecting shaft extends into the sleeve and is rotatably connected to the bottom end of the sliding rod. The pressing disc is disposed in the cylinder body and is fixedly connected to the bottom end of the connecting rod.

[0005] As a preferred embodiment of this utility model, the bottom end of the sliding rod is provided with a connecting groove, the top end of the connecting shaft is provided with a connecting post that matches the connecting groove, the top end of the connecting post extends into the connecting groove, and is rotatably connected to the sliding rod through a rotating shaft.

[0006] As a preferred embodiment of this utility model, a connecting bushing coaxially arranged with the through hole is installed on the top or bottom of the cylinder head, and a sealing ring that cooperates with the extrusion rod is provided inside the connecting bushing.

[0007] As a preferred embodiment of this utility model, the extrusion plate is provided with multiple liquid passage holes.

[0008] As a preferred embodiment of this utility model, the cylinder body is made of glass.

[0009] As a preferred embodiment of this utility model, a handle is fixedly connected to the top end of the connecting tube.

[0010] As a preferred embodiment of this utility model, the end face of the bottom end of the sleeve is fitted and connected to the end face of the top end of the connecting rod.

[0011] This utility model discloses a decoction machine, which has the following advantages compared with the prior art: During use, the sliding extrusion rod allows the extrusion disc to extrude the dregs bag, ensuring the quality of the decoction and simplifying operation. Under normal conditions, the top of the connecting shaft extends into the sleeve. At this time, the sleeve prevents the sliding rod from rotating relative to the connecting shaft, thus preventing accidental rotation of the extrusion rod during sliding and ensuring the normal operation of the extrusion process. When the connecting tube is lifted, and it slides upward relative to the sliding rod until the connecting shaft disengages from the sleeve, the sliding rod and connecting tube can rotate relative to the connecting shaft, thereby enabling the extrusion rod to rotate and fold, allowing the cylinder cover to be opened.

Detailed Implementation

[0017] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0018] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] like Figure 1-4 As shown, a preferred embodiment of the decoction machine of this utility model includes a cylinder 1, a cylinder cover 2, a pressing connecting rod, and a pressing disc 4. A heating disc 11 is provided at the bottom of the cylinder 1. The cylinder cover 2 is closable and covers the top of the cylinder 1. The top of the cylinder cover 2 has a through hole communicating with the interior of the cylinder 1. Generally, the through hole is vertically arranged. The pressing rod 3 slides through the through hole and extends into the interior of the cylinder 1. The pressing rod 3 includes a connecting pipe 31, a sliding rod 32, a spring 35, and a connecting rod 33. A sleeve 34 is fixed to the bottom end of the connecting pipe 31. The sleeve 34 is coaxially arranged with the connecting pipe 31. The diameter of the sleeve 34 is smaller than the diameter of the connecting pipe 31. The sliding rod 32... The sliding rod 32 is inserted into the connecting pipe 31 and slidably connected to the sleeve 34. The top end of the sliding rod 32 is provided with a limiting flange 321. The spring 35 is sleeved on the sliding rod 32 and located between the top end of the sleeve 34 and the bottom end of the limiting flange 321. The top end of the connecting rod 33 is provided with a connecting shaft 36. The diameter of the connecting shaft 36 is smaller than the diameter of the connecting rod 33. The top end of the connecting shaft 36 extends into the sleeve 34 and is rotatably connected to the bottom end of the sliding rod 32. Generally, the outer diameters of the connecting rod 33, the sleeve 34 and the connecting pipe 31 are the same and are compatible with the diameter of the through hole, thereby ensuring that the extrusion rod 3 has sufficient sliding stroke. The extrusion disc 4 is located in the cylinder 1 and is fixedly connected to the bottom end of the connecting rod 33.

[0020] The working principle of this embodiment is as follows: When in use, water and a bag of medicinal residue containing Chinese herbal medicine slices (the bag of medicinal residue is permeable to water) are placed into the cylinder 1. Then, the cylinder lid 2 is closed and heated by the heating plate 11. During the heating process, by repeatedly pressing down and lifting the extrusion rod 3, the extrusion plate 4 repeatedly squeezes the bag of medicinal residue, achieving the effect of kneading the medicine. That is, the bag of medicinal residue is squeezed and stirred under the sealed decoction state. Alternatively, the extrusion rod 3 can be pressed down so that the extrusion plate 4 fixes the bag of medicinal residue in an appropriate position, allowing the medicinal materials to be decocted in a state of full contact with water, which is conducive to the dissolution of effective ingredients, ensures the quality of decoction, and is easy to operate.

[0021] Under normal conditions, the top of the connecting shaft 36 extends into the sleeve 34. At this time, due to the obstruction of the sleeve 34, the sliding rod 32 cannot rotate relative to the connecting shaft 36, thereby preventing the extrusion rod 3 from rotating unexpectedly during the sliding process and ensuring the normal operation of the extrusion. When the connecting tube 31 is lifted until the extrusion plate 4 abuts against the bottom of the cylinder head 2, the connecting rod 33 can no longer move upward. Therefore, the connecting tube 31 will slide upward relative to the sliding rod 32, and the spring 35 will be compressed to generate elastic force. When the connecting shaft 36 is disengaged from the sleeve 34, the sliding rod 32 and the connecting tube 31 can rotate relative to the connecting shaft 36. At this time, the extrusion rod 3 can be rotated and folded so that the extrusion rod 3 hangs on the cylinder head 2 so that the cylinder head 2 can be opened (side-opening). Afterwards, after the connecting tube 31 is rotated to the vertical position, the extrusion rod 3 will return to the normal state under the elastic force of the spring 35.

[0022] For example, the bottom end of the sliding rod 32 is provided with a connecting groove 322, and the top end of the connecting shaft 36 is provided with a connecting post 361 that matches the connecting groove 322. The top end of the connecting post 361 extends into the connecting groove 322 and is rotatably connected to the sliding rod 32 through the rotating shaft 362, thereby realizing the rotatable connection between the connecting shaft 36 and the sliding rod 32.

[0023] For example, a connecting bushing 21 coaxially arranged with the through hole is installed on the top or bottom of the cylinder cover 2. The extrusion rod 3 passes through the connecting bushing 21. A sealing ring that cooperates with the extrusion rod 3 is provided in the connecting bushing 21, which can effectively prevent steam leakage during the cooking process and reduce heat loss. It is understood that in order to prevent the pressure in the cylinder body 1 from being too high, a pressure relief valve is provided on the cylinder cover 2.

[0024] For example, the extrusion plate 4 is provided with multiple liquid passage holes 41. When the extrusion plate 4 extrudes the drug residue bag, the liquid in the cylinder 1 will pass through the liquid passage holes 41, reducing the resistance to the extrusion plate 4 and facilitating operation.

[0025] For example, the cylinder 1 is made of glass, which allows for a clear view of the contents of the cylinder 1. Generally, the side of the cylinder 1 is provided with a scale for measuring the volume of the liquid inside the cylinder 1, so that water can be added in the correct amount.

[0026] For example, a handle 37 is fixedly connected to the top end of the connecting tube 31, which facilitates pressing down and lifting the extrusion rod 3, making operation convenient.

[0027] For example, the end face of the bottom end of the sleeve 34 is fitted and connected to the end face of the top end of the connecting rod 33 to ensure the overall flatness of the extrusion rod 3 and prevent the extrusion rod 3 from getting stuck when it slides in the through hole.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
