Description

Technical Field

[0001] This utility model belongs to the field of traditional Chinese medicine decoction equipment, specifically, it relates to a decoction pot with a lid for dispensing liquid. Background Technology

[0002] There are two main methods for discharging liquid from a decoction pot: top-discharging and bottom-discharging. With top-discharging, the lid must first be removed from the pot before inverting it to pour the medicine. Because the decoction pot is very hot after decocting, hot steam can easily burn the operator when the lid is removed.

[0003] The bottom-discharge check valve sealing structure is prone to failure due to long-term heat exposure, posing a risk of leakage. In addition, a bottom filter tank is required when dispensing medicine, resulting in a complex structure with many pieces of equipment.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] In order to solve at least some of the above-mentioned problems, this utility model provides a decoction pot with a lid that allows the decoction liquid to be poured out without removing the lid from the pot body. The decoction pot can be turned upside down so that the lid faces downwards.

[0006] The basic concept of the technical solution adopted in this utility model is:

[0007] A decoction pot with a lid and liquid outlet, comprising:

[0008] The pot body has a dispensing port at the top;

[0009] The lid is locked relative to the pot body and seals the inlet of the pot body;

[0010] A valve device is connected to the pot lid, and when the valve device is opened, it connects the inside of the pot to the outside.

[0011] Furthermore, the valve device includes:

[0012] The valve body is installed on the inside of the pot lid, and has a first chamber that communicates with the inside of the pot body and a first communication port that communicates with the first chamber.

[0013] A valve cover, installed on the outside of the pot lid, has an inlet for allowing the liquid medicine to drain or enter.

[0014] The pot lid is provided with a through opening that connects the inlet and the first connecting opening;

[0015] A valve stem is movably disposed within the inlet and the first communication port, and is used to control the connection or disconnection between the inlet and the first chamber.

[0016] Furthermore, when the valve stem is in the closed position, the first end of the valve stem extends out of the inlet;

[0017] When the valve stem is in the open position, the valve stem retracts into the inlet.

[0018] Furthermore, a channel for the liquid medicine to pass through is formed between the valve stem and the inlet;

[0019] The valve stem is provided with a stop portion, which is located in the first chamber. When the valve stem is in the closed position, the stop portion abuts against the valve cover.

[0020] Furthermore, a second elastic body is provided inside the valve body. The second elastic body is connected to the valve stem. When the valve stem is in the open position, the second elastic body compresses and stores force.

[0021] Furthermore, the valve body is also provided with a second chamber, which is connected to the first chamber through a second communication port;

[0022] The second end of the valve stem extends into the second chamber;

[0023] The second elastomer is located within the second cavity.

[0024] Furthermore, the lid is provided with a vent pipe extending to the bottom of the pot body, which connects the interior of the pot body with the atmosphere to balance the air pressure between the interior of the pot body and the atmosphere.

[0025] Furthermore, the vent pipe includes a first pipe section connected to the pot lid;

[0026] A second pipe section is provided at an angle to the first pipe section at the end furthest from the pot lid;

[0027] The second pipe section has a third pipe section extending towards the pot lid at the end away from the first pipe section, and there is a distance between the third pipe section and the pot lid.

[0028] Furthermore, the lid is locked to the pot body by multiple locking components;

[0029] The locking component includes:

[0030] The first end of the horizontal arm is connected to the pot body;

[0031] The flipping arm is flip-mounted on the horizontal arm and can be flipped in the direction of the pot lid.

[0032] A first elastic body is connected to the flipping arm and applies a force to the flipping arm to drive it to flip towards the pot lid.

[0033] When the flipping arm flips in the direction of the pot lid, the flipping arm is connected to the pot lid and applies a pressure to the pot lid in the direction of the pot body.

[0034] Furthermore, the edge of the pot lid is provided with a connecting sleeve that extends inward toward the inside of the pot lid;

[0035] When the lid closes the inlet of the pot body, the connecting sleeve covers the top of the pot body inside.

[0036] The outer side of the connecting sleeve is provided with an outwardly protruding snap-fit ​​part;

[0037] The flipping arm is provided with a protrusion that is angled to the flipping arm;

[0038] When the flipping arm is connected to the pot lid, the protrusion presses against the top of the locking part.

[0039] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.

[0040] After the decoction pot has finished decocting the herbs, simply turn it upside down so that the lid faces downwards and open the valve on the lid. The decocted liquid can then be discharged through the valve. Therefore, after the decoction pot has finished decocting the herbs, it is not necessary to open the lid to avoid the hot steam inside the pot overflowing when the lid is opened, which could burn the operator.

[0041] When pouring the medicinal liquid from one decoction pot into another, the decoction pot from which the liquid needs to be poured is inverted and moved above the decoction pot from which the liquid needs to be filled. The valve stem of the inverted decoction pot is aligned with the valve stem of the decoction pot below, and the inverted decoction pot is moved downwards. As the inverted decoction pot descends, the valve stems of both decoction pots move from the closed position to the open position. When the inlets of the two decoction pots are aligned, the medicinal liquid in the inverted decoction pot above flows into the decoction pot from which the liquid needs to be filled.

[0053] Reference Figures 1 to 4 This utility model discloses a decoction pot with a lid that allows liquid to be dispensed.

[0054] The decoction pot includes a pot body 1 and a lid 2 that covers the top of the pot body 1 and closes the inlet of the pot body 1. A locking mechanism is provided on the outer side wall of the top of the pot body 1. The locking mechanism is used to fix the lid 2 to the pot body 1, so that the lid 2 keeps the inlet of the pot body 1 closed.

[0055] In this embodiment, a valve device 4 is installed on the pot lid 2. When the valve device 4 is opened, the internal space of the pot body 1 is connected to the outside. A vent pipe 5 is installed on the pot lid 2. One end of the vent pipe 5 is connected to the inside of the pot body 1, and the other end is connected to the outside air. The vent pipe 5 can balance the air pressure between the internal space of the pot body 1 and the outside air.

[0056] After the decoction pot has finished decocting the herbs, there is no need to remove the lid 2 from the pot body 1. Instead, flip the pot body 1 together with the lid 2 and open the valve device 4. The herbs in the pot body 1 can then be poured out through the valve device 4. The vent pipe 5 connects the air pressure inside the pot body 1 with the outside air, ensuring that the decoction inside the pot body 1 can flow out through the valve device 4 under its own weight.

[0057] In this embodiment, the locking mechanism includes multiple locking components 3 that are fixedly connected to the pot body 1. The locking components 3 are arranged in a circular array with the central axis of the pot body 1 as the center line.

[0058] Specifically, the locking assembly 3 includes a horizontally arranged cross arm 31. The first end of the cross arm 31 is fixedly connected to the outer wall of the pot body 1, while the second end of the cross arm 31 is a free end. The connection between the cross arm 31 and the pot body 1 can be achieved by welding, bolting, or riveting. A vertically arranged tilting arm 32 is provided at the free end of the cross arm 31. The middle region of the tilting arm 32 in its extension direction is rotatably connected to the cross arm 31 via a pivot 321. The first end of the tilting arm 32 is located above the cross arm 31, and the second end of the tilting arm 32 is located below the cross arm 31, forming a seesaw structure at the free end of the cross arm 31.

[0059] In this embodiment, a distance is left between the first end of the flipping arm 32 and the outer wall surface of the pot body 1, and a similar distance is left between the second end of the flipping arm 32 and the outer wall surface of the pot body 1. A protrusion 322 extending towards the pot body 1 is provided at the first end of the flipping arm 32, and the angle between the protrusion 322 and the flipping arm 32 is a right angle. The protrusion 322 and the flipping arm 32 can be fixed together by welding, or the protrusion 322 and the flipping arm 32 can be integrally formed.

[0060] A first elastic body 33 is provided between the second end of the tilting arm 32 and the outer wall of the pot body 1. One end of the first elastic body 33 is fixedly connected to the outer wall of the pot body 1, and the other end of the first elastic body 33 is fixedly connected to the second end of the tilting arm 32. When the first elastic body 33 is in a non-stressed state, the tilting arm 32 is in a vertical state or tilted in the direction of the pot body 1.

[0061] In this embodiment, the edge of the pot lid 2 is provided with a connecting sleeve 21 extending inward towards the inside of the pot lid 2. The connecting sleeve 21 is welded and fixed to the pot lid 2 or integrally formed. The connecting sleeve 21 is cylindrical. The inner diameter of the connecting sleeve 21 is larger than the outer diameter of the pot body 1, so that when the pot lid 2 is placed on the pot body 1, the connecting sleeve 21 can cover the top of the pot body 1 inside.

[0062] The outer diameter of the connecting sleeve 21 is smaller than the distance between the first ends of the flipping arms 32 of the two opposing locking components 3. The axial length of the connecting sleeve 21 is greater than the distance between the flipping arm 32 and the top of the pot body 1, but less than the distance between the cross arm 31 and the top of the pot body 1. When the connecting sleeve 21 covers the top of the pot body 1, the connecting sleeve 21 extends between the first end of the flipping arm 32 and the pot body 1.

[0063] A snap-fit ​​part 211 extending outward is provided at the bottom of the outer wall surface of the connecting sleeve 21. The snap-fit ​​part 211 and the connecting sleeve 21 can be integrally formed, or the snap-fit ​​part 211 and the connecting sleeve 21 can be integrally formed.

[0064] Preferably, the bottom of the outer wall surface of the snap-fit ​​portion 211 is provided with a chamfer 2111.

[0065] In this embodiment, when the bottom of the connecting sleeve 21 extends into the space between the first end of the flipping arm 32 and the pot body 1, the locking part 211 is located below the protrusion 322 of the flipping arm 32. The protrusion 322 of the flipping arm 32 presses against the top surface of the locking part 211.

[0066] When the lid 2 is placed on the pot body 1, the flipping arm 32 is first rotated, causing its first end to flip towards the side opposite to the pot body 1. At this time, the second end of the flipping arm 32 applies force to the first elastic body 33, causing it to compress and store force. Then, the lid 2 is placed on the pot body 1, with the connecting sleeve 21 of the lid 2 covering the top of the pot body 1. The locking part 211 on the connecting sleeve 21 is located in the space between the flipping arm 32 and the pot body 1. Finally, the flipping arm 32 is released, the first elastic body 33 releases the stored force, and the flipping arm 32 is flipped, causing its first end to move towards the pot body 1. The protrusion 322 on the flipping arm 32 presses against the top of the locking part 211, and the protrusion 322 applies force to the locking part 211. As the protrusion 322 applies force to the locking part 211, the joint between the lid 2 and the pot body 1 can fit more tightly.

[0067] To prevent leakage at the joint between the lid 2 and the pot body 1, in this embodiment, the inner surface of the lid 2 is provided with a first annular groove 22. A first elastic sealing ring 23 is installed inside the first annular groove 22. The first elastic sealing ring 23 is embedded inside the first annular groove 22 and protrudes from the opening of the first annular groove 22.

[0068] When the lid 2 is placed on the pot body 1, the first annular groove 22 is aligned with the top rim of the pot body 1. When the lid 2 is locked by the locking mechanism, the first elastic sealing ring 23 is located between the lid 2 and the pot body 1, and the lid 2 and the pot body 1 compress the first elastic sealing ring 23. When the decoction pot is turned over to pour out the medicine, the first elastic sealing ring 23 located between the lid 2 and the pot body 1 ensures that the joint between the lid 2 and the pot body 1 is not prone to leakage.

[0069] In this embodiment, the valve device 4 includes a valve body 41 located inside the pot lid 2 and a valve cover 42 located outside the pot lid 2. The valve cover 42 and the valve body 41 are fixed together by bolts that pass through the pot lid 2. The valve body 41 and the valve cover 42 are connected by bolts and fit tightly against the pot lid 2.

[0070] An inlet 421 is provided on the valve cover 42, which penetrates the valve cover 42. The inlet 421 is provided from the side of the valve cover 42 facing the pot lid 2 to the side of the valve cover 42 away from the pot lid 2.

[0071] In this embodiment, a first chamber 411 and a second chamber 412 are provided inside the valve body 41, with the second chamber 412 located on the side of the first chamber 411 facing away from the pot lid 2. A first connecting port 413 is provided on the side of the valve body 41 facing the pot lid 2, and the first connecting port 413 communicates with the interior of the first chamber 411. A second connecting port 414 is provided between the first chamber 411 and the second chamber 412, connecting the interiors of the first chamber 411 and the second chamber 412. The first connecting port 413 and the second connecting port 414 are arranged opposite to each other.

[0072] A through-hole 25 is provided at a position opposite to the inlet 421 on the pot lid 2, and the through-hole 25 and the inlet 421 on the valve cover 42 are coaxially opposite each other. The first connecting port 413 of the valve body 41 is also coaxially opposite to the through-hole 25 on the pot lid 2.

[0073] The inlet 421, the first connecting port 413, the through port 25, and the second connecting port 414 are all circular holes. The diameter of the inlet 421 is smaller than that of the through port 25, while the diameters of the first connecting port 413 and the through port 25 are the same.

[0074] In this embodiment, the valve device 4 further includes a valve stem 43, which sequentially passes through an inlet 421, a through port 25, a first connecting port 413, a first chamber 411, and a second connecting port 414. The first end of the valve stem 43 is located outside the valve cover 42, and the second end of the valve stem 43 is located inside the second chamber 412. The valve stem 43 is movably disposed inside the valve body 41, and the direction of movement of the valve stem 43 is set along its own extension direction.

[0075] The diameter of the valve stem 43 is smaller than the orifice diameter of the inlet 421, thereby forming a channel for liquid to flow between the valve stem 43 and the orifice wall of the inlet 421. The valve stem 43 has a central hole that completely penetrates the valve stem 43 along its axis.

[0076] The diameter of the second connecting port 414 matches the diameter of the valve stem 43. An oil seal is installed at the top of the second connecting port 414, and the oil seal abuts against the outer wall surface of the valve stem 43.

[0077] A stop portion 431 extending outward is provided on the outer wall surface of the valve stem 43. The stop portion 431 is an annular structure that fits the valve stem 43 inside. The stop portion 431 and the valve stem 43 are integrally formed or welded together. The stop portion 431 is located inside the first chamber 411 and can move synchronously with the valve stem 43 inside the first chamber 411. The outer diameter of the stop portion 431 is larger than the diameter of the inlet 421 and smaller than the diameter of the through port 25.

[0078] The valve stem 43 can move in both open and closed positions.

[0079] When the valve stem 43 is in the closed position, the stop part 431 abuts against the valve cover 42. The stop part 431 seals the passage between the valve stem 43 and the inlet 421, disconnects the inlet 421 from the first chamber 411, and the first end of the valve stem 43 extends out of the inlet 421.

[0080] When the valve stem 43 is in the open position, the stop part 431 is separated from the valve cover 42, the passage between the valve stem 43 and the inlet 421 is opened, the first chamber 411 is connected to the inlet 421, and the first end of the valve stem 43 is retracted into the inlet 421.

[0081] In this embodiment, a connecting structure is provided on the wall of the first chamber 411, which connects the first chamber 411 to the internal space of the pot body 1. The medicinal liquid being decocted in the pot body 1 can enter the interior of the first chamber 411 through the connecting structure. The connecting structure can be a hole that passes through the valve body 41 to connect the interior of the first chamber 411 and the interior of the pot body 1.

[0082] The valve stem 43 is also provided with a connecting ring 432 extending outward along the radial direction of the valve stem 43. The connecting ring 432 is integrally formed with the valve stem 43, welded to it, or threadedly connected. The connecting ring 432 is located inside the second chamber 412, and the connecting ring 432 can move in the second chamber 412 when the valve stem 43 moves.

[0083] Inside the second chamber 412, a second elastic body 44 is also provided. The second elastic body 44 is a spring. The spring is fitted on the valve stem 43. One end of the spring abuts against the connecting ring 432, and the other end of the spring abuts against the cavity wall of the second chamber 412.

[0084] When the valve stem 43 is in the open position, the inlet 421 is connected to the first chamber 411, and the connecting ring 432 compresses the second elastic body 44, causing the second elastic body 44 to compress and store force. When the thrust applied to the valve stem 43 is released, the second elastic body 44 releases the force, pushing the valve stem 43 to move outward towards the pot lid 2, causing the stop part 431 on the valve stem 43 to abut against the valve cover 42, disconnecting the inlet 421 from the first chamber 411. At this time, the valve stem 43 returns to the closed position.

[0085] To improve the sealing between the stop 431 and the valve cover 42 when the stop 431 disconnects the inlet 421, a second annular groove 422 is formed on the surface of the valve cover 42 facing the through-hole 25. The second annular groove 422 is coaxially arranged with the inlet 421 and surrounds the inlet 421 on its inner side. A second elastic sealing ring 423 is embedded inside the second annular groove 422 and protrudes from the inside of the second annular groove 422. When the stop 431 is in contact with the valve cover 42, the stop 431 compresses the second elastic sealing ring 423, improving the sealing at the contact point between the stop 431 and the valve cover 42.

[0086] A third annular groove 424 is provided on the surface of the valve cover 42 facing away from the pot cover 2. The third annular groove 424 is coaxially arranged with the inlet 421. The third annular groove 424 surrounds the inlet 421 on the inner side. A third elastic sealing ring 425 is embedded inside the third annular groove 424, and the third elastic sealing ring 425 protrudes from the groove opening of the third annular groove 424.

[0087] In this embodiment, the vent pipe 5 includes a vertically arranged first pipe section 51, one end of which penetrates through the pot lid 2 and is sealed and fixed therebetween. The other end of the first pipe section 51 extends toward the bottom of the pot body 1. A second pipe section 52 is provided at the end of the first pipe section 51 extending toward the bottom of the pot body 1, and the second pipe section 52 is connected to the first pipe section 51. The angle between the second pipe section 52 and the first pipe section 51 is a right angle. A third pipe section 53 is provided at the end of the second pipe section 52 away from the first pipe section 51, extending toward the direction of the pot lid 2, and the third pipe section 53 is connected to the interior of the second pipe section 52. The third pipe section 53 is parallel to the first pipe section 51. A distance is left between the third pipe section 53 and the pot lid 2.

[0088] Preferably, the first pipe section 51, the second pipe section 52 and the third pipe section 53 are formed by continuously bending a single pipe.

[0089] The vent pipe 5 is used to connect the internal space of the pot body 1 with the outside air. When the medicinal materials in the decoction pot are poured out, the vent pipe 5 can balance the pressure of the air inside the pot body 1 and the outside air, so that the medicinal liquid can be poured out smoothly from the valve device.

[0090] A handle 24 is provided on the outside of the pot lid 2, and the top of the handle 24 is lower than the top of the valve stem 43 when it is in the closed position.

[0091] When pouring the medicinal liquid from one decoction pot into another, the decoction pot from which the liquid needs to be poured is inverted and placed above the decoction pot from which the liquid needs to be filled. The valve stem 43 of the inverted decoction pot is aligned with the valve stem 43 of the lower decoction pot, causing the inverted decoction pot to move downwards. As the inverted decoction pot descends, the valve stems 43 of both decoction pots move from the closed position to the open position. When the inlets 421 of the two decoction pots are aligned, the medicinal liquid in the upper, inverted decoction pot flows into the decoction pot from which the liquid needs to be filled through the inlet 421.
