Description

Technical Field

[0001] This utility model relates to a plant essence extraction device. Background Technology

[0002] Existing plant extract extraction equipment is equipped with an extractor and an extractor storage device: the plant powder to be extracted is placed in the extractor, soaked in hot water, and then filtered to remove the residue, thereby extracting the extract and sending it into the storage device.

[0003] The aforementioned plant extract extraction equipment includes: a water tank for storing water; and a water supply system for heating the water into hot water and delivering it to the extractor. However, in this plant extract extraction equipment, the hot water pipeline of the water supply system contains a large amount of steam. Therefore, sometimes due to the steam pressure, the hot water mixed with steam is forcefully ejected from the outlet and splashes, potentially hitting users and posing a safety hazard. Utility Model Content

[0004] The purpose of this invention is to provide a plant essence extraction device that provides a more stable plant essence liquid flowing from the outlet and prevents liquid splashing.

[0005] Therefore, the plant essence extraction device of this utility model includes: an extractor, a water tank, and a water supply device connected to the water tank via a water supply pipe, the water supply device being used to supply hot water to the extractor; it also includes a heater for heating water flowing from the water tank and through the water supply pipe into hot water; the water supply device includes a water outlet unit; the water outlet unit includes an inner cavity, on which an inlet and an outlet are provided; the inner cavity has a wall portion opposite to the inlet, which causes the hot water flowing in from the inlet to collide with the wall portion in the inner cavity; the top wall of the inner cavity has multiple vent holes for venting steam from the inner cavity. Simultaneously, when the water outlet unit outputs hot water from the outlet, it can introduce outside air into the inner cavity through the vent holes, facilitating a stable water flow output from the outlet.

[0006] Preferably, the cross-sectional area of ​​the hot water flow channel in the inner cavity is larger than the cross-sectional area of ​​the water supply pipe.

[0007] Preferably, the water outlet unit is provided with an exhaust port for discharging steam from the internal space.

[0008] Preferably, the cross-sectional area of ​​the water flow in the inner cavity of the water outlet unit gradually decreases in the downstream region along the direction of hot water flow; wherein the cross-sectional area of ​​the water flow in the inner cavity near the water outlet is the smallest.

[0009] Preferably, the bottom of the internal space of the water outlet unit is a slope. This sloped design ensures that the upper part of the hot water flow direction within the cavity is higher than the lower part. Furthermore, the water outlet should be located downstream of the hot water flow direction, and preferably on the aforementioned sloped surface, lower than the water inlet.

[0010] In the extractor, plant powders are soaked in hot water and then filtered through a filter to extract plant essences, which are then stored in a collection vessel.

[0011] In this invention, the diameter of the water outlet of the aforementioned water outlet unit is preferably at least the same as, or smaller than, the diameter of the liquid inlet. This reduces the steam pressure of the hot water flowing into the inner cavity from the water inlet, thereby reducing the flow velocity of the hot water in the inner cavity. Therefore, the hot water flowing out of the water outlet will be more stable.

[0012] Compared to existing technologies, the technical advantages of this invention are as follows: The design of the wall allows hot water entering the inner cavity from the inlet to collide and mix, separating steam from the hot water and expelling it from the inner cavity through the vent. This not only reduces the impact force of steam pressure on the hot water ejected from the outlet but also reduces the flow instability of the hot water ejected from the outlet. Based on this structure, the steam pressure of the hot water flowing into the inner cavity from the water pipe can be reduced, thereby weakening the flow velocity of the hot water within the inner cavity. Therefore, the hot water flowing from the outlet is more stable. This, in turn, results in a more stable flow of plant essence liquid from the outlet, preventing splashing of the plant essence liquid. Attached Figure Description

Detailed Implementation

[0014] The plant extractor 1 of this embodiment, under user operation, can automatically produce plant extract liquid using plant powder (such as crushed tea leaves, Chinese medicinal herbs, etc. with a particle size of 0.5-3mm) and hot water. This plant extractor is an immersion-type plant extractor: first, the plant powder is soaked in hot water for a certain period of time, and then the plant residue is filtered out through a filter to obtain the plant extract liquid.

[0015] like Figures 1 to 2 The plant essence extraction device 1 consists of the following components: a collection vessel 2, a placement platform 3, a support column 4, a water supply device 5, an extractor 6, a water tank 7, a heater 8, and a water supply pipe 9. The placement platform 3 is located at the bottom of the plant essence extraction device 1 and is used to place the collection vessel 2. The support column 4 extends upward from the rear end of the placement platform 3 and is connected to the water supply device 5. The water supply device 5 is located at the upper end of the plant essence extraction device 1, installed above the extractor 6, with the collection vessel 2 located below the extractor 6. The water supply device 5 contains a water outlet unit 50. Viewed from the side, the plant essence extraction device 1 has an overall shape roughly resembling a "C".

[0016] like Figures 2 to 7 The water outlet unit 50 includes an inner cavity 51, on which an inlet 52 and an outlet 53 are provided. The inlet 52 is located at the rear end of the inner cavity 51, while the outlet 53 is located at the lower front end of the inner cavity 51.

[0017] The extractor 6 has a funnel-shaped structure and contains a filter (usually a single or multiple layer of cloth filter). The extractor 6 is located above the collection vessel 2 and below the water supply device 5.

[0018] The water tank 7 is used to store water for extracting plant essence. The water tank 7 is installed on the upper rear part of the support column 4.

[0019] The heater 8 is an electric or electromagnetic heater for heating water, and it is installed inside the placement platform 3. Inside the placement platform 3, the heater 8 is located below the surface adjacent to the platform 3. When energized, the heater 8 heats the plant essence in the collection vessel 2 on the placement platform 3. Furthermore, the heater 8 also heats the water supply pipe 9, thereby heating the water flowing from the water tank 7 and through the water supply pipe 9 into hot water.

[0020] The water supply pipe 9 may include multiple water pipes for transporting water stored in the water tank 7 and for generating hot water after being heated by the heater 8. The water supply pipe 9 is installed in the support column 4 and the placement platform 5 and is connected to the water tank 7 and the water supply device 5.

[0021] A water pump is installed on the water supply pipe 9 or in the water tank 7. When the user starts the water pump through the control device such as the operation panel, the water in the water tank 7 is heated by the heater 8 through the water supply pipe 9 and then sent to the water supply unit 5.

[0022] The water supply pipe 9 extends downward from the outlet at the lower end of the water tank 7, enters the interior of the placement platform 3, and is positioned near the lower side of the heater 8. The water flowing in the water supply pipe 9 is heated by the heater 8 and converted into hot water. The hot water flowing in the water supply pipe 9 flows into the inner cavity 51 through the inlet 52 of the water outlet unit 50 of the water supply device 5, and then flows out from the outlet 53. The hot water flowing out from the outlet 53 is injected into the extractor 6. Subsequently, this hot water wets the plant powder in the extractor 6, and then filters it through a filter. The extracted plant essence flows out from the outlet at the lower part of the extractor 6 and flows into the collection pot 2.

[0023] like Figure 3-4 The water outlet unit 50 includes an inner cavity 51, a wall portion 54, a vent 55, a water storage portion 56, and an inclined portion 57. The wall portion 54 is located within the inner cavity 51, dividing it into an upstream space 51a and a downstream space 51b. The wall portion 54 protrudes downwards from the top surface of the water outlet unit 50 within the inner cavity 51, with a gap between its lower end and the bottom surface of the water outlet unit 50; this gap allows communication between the upstream space 51a and the downstream space 51b. The design of the wall portion 54 allows hot water containing a significant amount of steam flowing in from the inlet 52 to collide within it; the wall portion 54 is located directly opposite the inlet 52, and from the front, it completely overlaps with the inlet 52.

[0024] Because the wall 54 of the water outlet unit 50 is designed to collide with the hot water flowing into the inner cavity 51 (i.e., the upstream space 51a) from the inlet 52, gas can be effectively separated from the hot water. This not only reduces the influence of steam pressure on the velocity of the hot water ejected from the outlet 53, but also reduces flow turbulence and splashing when the hot water is ejected from the outlet 53. Therefore, the flow state of the hot water ejected from the outlet 53 is more stable.

[0025] The cross-sectional area of ​​the hot water flow channel in the inner cavity 51 of the water outlet unit 50 is larger than that in the hot water flow channel in the water supply pipe 9. Therefore, the steam pressure of the hot water flowing into the inner cavity 51 from the water supply pipe 9 can be reduced, thereby weakening the flow velocity of the hot water in the inner cavity 51. In this way, the hot water sprayed from the outlet 53 can be more stable.

[0026] The diameter of the outlet 53 of the water outlet unit 50 should be at least the same as, or smaller than, the diameter of the inlet 52. This design reduces the steam pressure of the hot water flowing into the inner cavity 51 from the inlet 52, thereby reducing the flow velocity of the hot water in the inner cavity 51. Therefore, the flow rate of hot water ejected from the outlet 53 can remain relatively stable.

[0027] Vent holes 55 are used to discharge steam from the water outlet unit 50, enabling steam in the inner cavity 51 to be released to the outside of the water outlet unit 50. These vent holes 55 are connected to the inner cavity 51 (especially the downstream space 51b). The vent holes 55 are designed to penetrate the upper surface of the water outlet unit 50; in addition, these vent holes 55 are also arranged near the downstream side of the wall portion 54.

[0028] Since the vent 55 on the water outlet unit 50 can discharge steam from the inner cavity 51, it can effectively prevent steam from accumulating in the inner cavity 51. In addition, since the vent 55 is located near the downstream of the wall 54, it can stably discharge the steam that separates from the hot water after colliding with the wall 54 to the external space.

[0029] When the water outlet unit 50 sprays hot water through the water outlet 53, it can also draw outside air into the inner cavity 51 through the vent 55. Therefore, it can stably achieve the function of spraying hot water through the water outlet 53.

[0030] On the vent 55 of the water outlet unit 50, a plurality of ribs 58 are provided across the vent 55; these ribs divide the vent 55 into multiple parts (four parts in this embodiment). Due to the provision of these ribs, even if there are multiple vents 55, the rigidity of the upper part of the water outlet unit 50 can be guaranteed; at the same time, it can also effectively prevent foreign objects from entering the inner cavity 51 through the vents 55.

[0031] The water storage section 56 of the water outlet unit 50 is located within the downstream space 51b. The water storage section 56 is formed by this relatively large area of ​​the downstream space 51b, and therefore can be used to store hot water. In this way, even if the pump suddenly stops during the extraction of the plant essence, causing the hot water inside the heater 8 to rapidly flow into the water outlet unit 50, the water storage section 56 can effectively store this hot water, thereby preventing hot water from overflowing from the vent 55.

[0032] In the downstream region along the hot water flow direction, the cross-sectional area of ​​the inner cavity 51 of the water outlet unit 50 gradually decreases; the cross-sectional area of ​​the inner cavity 51 near the outlet 53 is the smallest, so as to effectively guide the hot water to the outlet 53, thereby making the water pressure of the hot water in the inner cavity 51 more stable.

[0033] The lower part of the inner cavity 51 of the water outlet unit 50 is formed by an inclined surface 57. This inclined surface design ensures that the upstream side of the water flow direction in the internal space is at a higher position, while the downstream side is at a lower position. The water outlet 53 is located downstream of the water inlet 52, and the inclined surface 57 is lower than the water inlet 52. Through this design, hot water can flow in the inner cavity 51 along a predetermined path, thereby effectively stabilizing the flow state of the hot water.

[0034] The inlet 52 and outlet 53 of the water outlet unit 50 are arranged along the flow direction of hot water in the inner cavity 51 in the plan view. Due to this structure, the flow of hot water from the inlet 52 to the outlet 53 in the inner cavity 51 can be effectively stabilized.
