Description

Technical Field

[0001] The present invention relates to the field of tea extraction machines, in particular to a high-pressure segmented tea extraction machine. Background Art

[0002] In modern society, with the improvement of people's living standards and the change of consumption concepts, tea, as a healthy and fashionable beverage, has been loved by more and more people. The scale of the tea beverage market continues to expand, and the demand for tea beverages is showing a rapid growth trend, whether in traditional teahouses, emerging milk tea shops, or daily home drinking. However, traditional tea brewing methods have many limitations and cannot meet the market's growing demand for diversity and high quality.

[0003] The traditional way of making tea mainly relies on manually placing tea leaves into a container and extracting them by soaking them in hot water. This method has the problem of low efficiency. Each time you make tea, you need to wait for the tea leaves to be fully soaked, which generally takes several minutes or even longer, and cannot meet the needs of fast-paced life and large orders in commercial places. Moreover, the quality of manual tea brewing depends to a large extent on the experience and technique of the tea maker. The tea brewed by different people varies greatly in taste, aroma, concentration, etc., making it difficult to ensure the stability and consistency of product quality. In addition, the traditional way of making tea has a low utilization rate of tea leaves. Due to insufficient soaking, the effective ingredients in the tea leaves cannot be completely precipitated, resulting in a waste of raw materials and increased production costs. In order to solve these problems of the traditional way of making tea, tea extraction machines came into being;

[0004] At present, the equipment for making tea soup on the market is mainly divided into two categories: one is to place tea leaves into a large-capacity tea barrel, inject high-temperature water, and obtain tea soup after a long soaking period. During the soaking process, heat loss is large, and the flavor of the tea soup is not good. The tea soup is preserved in an insulation barrel, and the production process takes a long time. The large capacity cannot be used in time, and the tea soup is not fresh; the second type is modified from a coffee machine, which can be ground and extracted immediately. Since the tea leaves need to go through the segmented processes of water injection, soaking, and tea soup, after the water injection is stopped, the brewing head is depressurized, and the soaking process is in a pressure-free state, the extraction time is reduced, and at the same time, part of the tea soup is depressurized, resulting in waste, which is especially obvious when there are many segments. For this reason, we proposed a high-pressure segmented tea extraction machine. Summary of the Invention

[0005] Purpose of the invention: The purpose of the present invention is to provide a high-pressure segmented tea extraction machine that can shorten the tea preparation time, reduce heat loss, and ensure that the tea flavor is rich and fresh; another purpose of the present invention is to provide a high-pressure segmented tea extraction machine that can maintain a high-pressure environment during the segmented extraction process, improve the extraction time, avoid tea waste, and improve the utilization rate of tea leaves.

[0006] Technical solution: A high-pressure segmented tea extraction machine includes a base, a shell is installed on the upper surface of the base, a water pump is installed on the left side of the inside of the shell, a one-way valve is installed on the top of the output end of the water pump, a flow meter is installed on the output end of the one-way valve, a boiler 1 is fixedly installed on the output end of the flow meter, a boiler 2 is installed on the output end of the boiler 1, a two-way solenoid valve is fixedly installed on the output end of the boiler 2, a three-way solenoid valve is fixedly installed on the output end of the two-way solenoid valve, a brewing head is fixedly installed on the output end of the three-way solenoid valve, a filter valve is embedded in the left side of the outer wall of the brewing head, a heater is embedded in the front of the outer wall of the brewing head, an extraction handle is installed on the bottom of the brewing head, and a cup-dispensing mechanism is fixedly installed on the front surface of the shell.

[0007] Furthermore, the cup-dispensing mechanism includes a storage box, and the interior of the storage box has two through-type storage openings.

[0008] Furthermore, the front surface of the shell is fixedly connected to guide rails on both sides of the storage box, and the interior of the guide rails is fixedly and slidably connected to sliding bars, and the opposite sides of the two sliding bars are fixedly connected to the two sides of the storage box respectively.

[0009] Furthermore, an annular groove is integrally formed below the inner side wall of the storage opening, and a through-type movable opening is opened on the opposite sides of the two annular grooves.

[0010] Furthermore, a plurality of plastic cups are sequentially engaged and placed on the inner side of the storage opening from top to bottom, and an anti-slip ring is integrally formed on the top of the plastic cup. Both sides of the storage box are fixedly connected with fixed bars in front and behind the two movable openings, and two movable bars are arranged between the two fixed bars facing each other. The back sides of the two movable bars facing each other are fixedly connected with guide rods, and the end of the guide rod away from the movable bar passes through the fixed bar and is slidably connected to the fixed bar.

[0011] Furthermore, the inner lower surface of the movable bar is rotatably connected to a screw rod through a rotating shaft, the outer side wall of the screw rod is threadedly connected to a screw sleeve, and the opposite sides of the two screw sleeves facing each other are located on the inner side of the movable port and are fixedly connected to a connecting bar, one end of the connecting bar extends to the inner side of the storage port, and an arc-shaped limiting ring is integrally formed.

[0012] Furthermore, both sides of the storage box are fixedly connected to an axle seat below the movable opening, the inner side of the axle seat is rotatably connected to a rotating rod via a rotating shaft, the bottom end of the rotating rod is fixedly connected to a bottom cover, the top end of the rotating rod is fixedly connected to a spiral column, the outer side wall of the spiral column is spirally installed with a spiral sleeve, the outer side wall of the spiral sleeve is rotatably connected to two traction rods via a rotating shaft, the top end of the traction rod is rotatably connected to a rotating head via a rotating shaft, and the top of the rotating head is fixedly connected to the bottom of the movable bar.

[0013] Furthermore, the top end of the screw rod passes through the top of the movable bar and is fixedly connected to a knob.

[0014] Furthermore, a spring is fixedly connected to the opposite sides of the fixed bar and the movable bar and located on the outside of the guide rod.

[0015] Beneficial effects: Through the three-stage heating of boiler 1, boiler 2, and brewing head, the temperature during the working process can be guaranteed to be stable and the endurance time is long. The use of high-precision flow meter has higher accuracy and ensures the consistency of flow during multiple production processes;

[0016] The process of water injection, soaking and liquid discharge is controlled by a two-way solenoid valve and a three-way solenoid valve: in the first stage, the two-way solenoid valve and the three-way solenoid valve are opened, and the water pump is started at the same time to inject water into the extraction handle. When the extraction handle is filled, the two-way solenoid valve is closed, and the three-way solenoid valve remains open, and the water injection is completed. In the second stage, the pressure in the extraction handle is maintained for soaking, and the set soaking time is maintained. In the third stage, the two-way solenoid valve is opened, and the water pump is started at the same time to continue to inject water into the extraction handle. The one-way valve of the extraction handle is opened, and the tea soup is discharged to the set flow rate. At the same time, the two-way solenoid valve and the three-way solenoid valve are closed. The pressure in the extraction handle is released through the three-way solenoid valve, and the handle can be smoothly removed to complete the entire extraction process. If necessary, the second and third stages can be repeated. Before the entire production process is completed, the three-way solenoid valve is always kept open to maintain the pressure in the extraction handle;

[0017] The cup retrieval process is simple and easy to understand. Simply manually turn the bottom cover, and a series of mechanical transmissions will limit the plastic cup, allowing you to easily remove the bottom cup. This eliminates the need for complex operating steps, reducing user difficulty and improving cup retrieval efficiency. For places with large traffic, it can quickly meet the cup retrieval needs of multiple people.

[0018] The knob can flexibly control the rotation of the screw, thereby adjusting the position of the screw sleeve and the arc-shaped limit ring. The number of plastic cups removed at a time can be precisely controlled according to actual needs. Whether taking out a single cup or multiple cups at once, it can be easily achieved, greatly improving the applicability and flexibility of the device. It can be widely used in different scenarios, such as homes, offices, tea shops, etc.

[0019] The various components of the device work closely together through guide rails, sliding bars, rotating shafts, and threaded connections to form a stable mechanical transmission system. The spring setting provides a reset function for components such as the movable bar, ensuring that the device can return to its initial state after each operation, ensuring the normal operation of subsequent cup removal operations. The entire device has a compact structure, stable operation, a long service life, and a low failure rate.

[0020] The storage opening in the storage box adopts a multi-layer stacking design of plastic cups, which makes full use of the vertical space and saves overall space. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example:

[0031] like Figure 1 and Figure 2 As shown, a high-pressure segmented tea extraction machine is provided, which includes a base 12, a shell 13 is installed on the upper surface of the base 12, a water pump 1 is installed on the left side of the inner part of the shell 13, a one-way valve 2 is installed on the top of the output end of the water pump 1, a flow meter 3 is installed on the output end of the one-way valve 2, a boiler 1 4 is fixedly installed on the output end of the flow meter 3, a boiler 2 5 is fixedly installed on the output end of the boiler 1 4, a two-way solenoid valve 6 is fixedly installed on the output end of the boiler 2 5, a three-way solenoid valve 8 is fixedly installed on the output end of the two-way solenoid valve 6, a brewing head 9 is fixedly installed on the output end of the three-way solenoid valve 8, a filter valve 7 is embedded in the left side of the outer wall of the brewing head 9, a heater 11 is embedded in the front side of the outer wall of the brewing head 9, and an extraction handle 10 is installed at the bottom of the brewing head 9;

[0032] Water pump 1 draws incoming water and pressurizes it to the appropriate pressure; one-way valve 2 prevents hot water from flowing back and contaminating the water source, while keeping the back end full of water to ensure accurate water flow measurement; flowmeter 3 measures water volume; boiler 1 4 stores hot water to ensure that the water temperature flowing to the next heating device does not fluctuate much; boiler 2 5 stores hot water to further reduce the temperature variation of the outlet water; two-way solenoid valve 6 controls the extraction process; three-way solenoid valve 7 controls the overall extraction process and pressure relief; filter valve 8 filters impurities and protects the solenoid valve; brewing head 9 is used to install the extraction handle 10 and keep it warm; the extraction handle 10 is used to place tea leaves and maintain the extraction pressure; heater 11 heats and keeps the brewing head 9 warm.

[0033] When the device is in use, it is activated, and boiler 1 4, boiler 2 5, and brewing head 9 begin heating. When the temperature reaches the set value, they stop heating and can begin operation. Tea leaves are placed in the extraction handle 10, which is then mounted on the brewing head 9. The extraction button is pressed, opening the two-way solenoid valve 6, filter valve 7, and three-way solenoid valve 8. Water pump 1 is simultaneously activated, and hot water at the set temperature is injected into the extraction handle 10. The current water output is calculated by detecting the pulses of flowmeter 3. When the water output reaches the set flow rate, the corresponding valve is closed, and water pump 1 is stopped. During operation, if one of the heating devices detects a drop in temperature, it will promptly start heating to the set temperature. The device is always maintained at the appropriate temperature and pressure.

[0034] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, a cup-dispensing mechanism 14 is fixedly mounted on the front surface of the housing 13;

[0035] The cup dispensing mechanism 14 includes a storage box 15 , and the storage box 15 has two through-type storage openings 16 ;

[0036] The front surface of the housing 13 is fixedly connected to guide rails 17 on both sides of the storage box 15. Sliding bars 18 are fixedly and slidably connected inside the guide rails 17. The opposite sides of the two sliding bars 18 are fixedly connected to the two sides of the storage box 15 respectively.

[0037] An annular groove 19 is integrally formed below the inner side wall of the storage opening 16, and two annular grooves 19 are provided with through-type movable openings 20 on opposite sides thereof.

[0038] A plurality of plastic cups 21 are sequentially engaged and placed on the inner side of the storage opening 16 from top to bottom. An anti-drop ring 22 is integrally formed on the top of the plastic cups 21. Fixed bars 23 are fixedly connected to the front and rear of the two movable openings 20 on both sides of the storage box 15. Two movable bars 24 are provided between the two opposite fixed bars 23. A guide rod 25 is fixedly connected to the opposite sides of the two movable bars 24. The end of the guide rod 25 away from the movable bar 24 passes through the fixed bar 23 and is slidably connected to the fixed bar 23.

[0039] The inner lower surface of the movable bar 24 is rotatably connected to a screw rod 26 via a rotating shaft. The outer wall of the screw rod 26 is threadedly connected to a screw sleeve 27. The opposite sides of the two screw sleeves 27 are located inside the movable opening 20 and are fixedly connected to a connecting bar 28. One end of the connecting bar 28 extends to the inside of the storage opening 16 and is integrally formed with an arc-shaped limiting ring 29.

[0040] On both sides of the storage box 15, below the movable opening 20, there are fixedly connected shaft seats 30. The inner side of the shaft seat 30 is rotatably connected to a rotating rod 31 via a rotating shaft. The bottom end of the rotating rod 31 is fixedly connected to a bottom cover 32. The top of the rotating rod 31 is fixedly connected to a spiral column 33. A spiral sleeve 34 is spirally installed on the outer wall of the spiral column 33. The outer wall of the spiral sleeve 34 is rotatably connected to two traction rods 35 via a rotating shaft. The top of the traction rod 35 is rotatably connected to a rotating head 36 via a rotating shaft. The top of the rotating head 36 is fixedly connected to the bottom of the movable bar 24.

[0041] The top end of the screw rod 26 passes through the top of the movable bar 24 and is fixedly connected to the knob 37;

[0042] A spring 38 is fixedly connected to the opposite side of the fixed bar 23 and the movable bar 24 and located on the outside of the guide rod 25;

[0043] Under normal conditions, the bottom cover 32 is pushed by the spring 38 to tightly cover the bottom of the storage opening 16, and its upper surface is completely in contact with the bottom of the storage box 15, forming a closed structure at the bottom of the storage opening 16. At this time, the rotating rod 31 is perpendicular to the bottom of the storage box 15, and the spiral column 33 is in its initial position. Due to the position of the bottom cover 32, the traction rod 35, the rotating head 36, the movable bar 24 and other components are in their initial distribution state under the action of the spring 38. The two adjacent arc-shaped limiting rings 29 are in a separated state and stored in the annular groove 19. Their position is lower than the anti-drop ring 22 of the penultimate plastic cup 21, and will not hinder the gravity drop of multiple plastic cups 21, so that the plastic cups 21 can be freely stacked in the storage opening 16 under the action of gravity.

[0044] When the teacup 21 is to be taken out, the operator manually rotates the bottom cover 32, and the bottom cover 32 rotates around the rotating shaft inside the shaft seat 30, gradually moving away from the bottom of the storage opening 16. As the bottom cover 32 rotates, the rotating rod 31 rotates synchronously, driving the spiral column 33 at the top to rotate. The rotation of the spiral column 33 causes the spiral sleeve 34 to spirally rise along its outer wall. During the rising process of the spiral sleeve 34, the two traction rods 35 are driven to move upward synchronously through the rotating shaft. When the traction rod 35 moves upward, the movable bar 24 is pulled by the rotating head 36 to overcome the elastic force of the spring 38 and move toward the middle, so that the two arc-shaped limiting rings 29 are close to each other and finally clamped under the anti-slip ring 22 of the second-to-last plastic cup 21 inside the storage opening 16. The cooperation of the arc-shaped limiting ring 29 and the anti-slip ring 22 limits and fixes the second-to-last plastic cup 21 and the multiple plastic cups 21 above it. At this time, the lowest plastic cup 21 loses the upper obstruction, and the operator can easily remove the lowest plastic cup from the bottom of the storage opening 16 for receiving tea.

[0045] When multiple plastic cups 21 need to be taken out at the same time, the operator can hold the knob 37 and rotate the knob 37 to drive the screw 26 to rotate. When the screw 26 rotates, the screw sleeve 27 threadedly connected to it will rise or fall according to the rotation direction of the screw 26. The rise and fall of the screw sleeve 27 drives the connecting bar 28 to move synchronously, thereby causing the arc-shaped limit ring 29 at one end of the connecting bar 28 to rise or fall. The operator can accurately control the clamping limit position of the arc-shaped limit ring 29 according to the number of plastic cups 21 that need to be taken out at a time. For example, if three plastic cups need to be taken out, the arc-shaped limit ring 29 can be adjusted to clamp under the anti-slip ring of the fourth-to-last plastic cup, thereby realizing the operational requirement of taking out multiple plastic cups 21 at the same time.

[0046] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
