Description

Technical Field

[0001] The invention relates to the technical field of tea beverage preparation, in particular to a preparation table for instant beverages. Background Art

[0002] Ready-to-drink beverages are a common type of beverage that is made and sold immediately, such as milk tea, fruit tea, and coffee. They are usually made on-site at a production table set up in the store.

[0003] For example, the existing Chinese patent publication number is CN215125984U, titled "A Beverage Preparation Bar for a Beverage Shop." The patent includes "a table body, a baffle, the bottom of the baffle being fixedly connected to the top of the table body, a garbage crushing device and an odor filtering device installed inside the table body, a cleaning pool on the top of the table body, and an adjustable material box inside the baffle."

[0004] An insulated bucket for temporarily storing liquid materials is usually placed on the top of the existing preparation table. When taking out the materials, the valve under the insulated bucket is directly opened to take out the materials. Since the insulated bucket is usually a closed structure when in use, as the liquid in the insulated bucket is released less, under the action of pressure, the outflow speed of the liquid in the bucket during release also decreases, or even no liquid flows out. A common method is to provide an air flow hole connected to the atmosphere on the insulated bucket, but this will reduce the sealing performance of the insulated bucket. In order to solve the above problem, we have proposed a preparation table for instant drinks. Summary of the Invention

[0026] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Please refer to Figures 1-6 , a beverage-making table for instant beverages provided by an embodiment of the present invention includes a table body 1, a plurality of heat preservation barrels 2 are arranged on the table body 1, a nitrogen supply mechanism 3 is installed on the table body 1, and the nitrogen output end of the nitrogen supply mechanism 3 is connected to each heat preservation barrel 2 through a pipe valve mechanism 4, and the internal pressure of each heat preservation barrel 2 is greater than the external pressure;

[0028] Specifically, the table body 1 is an existing stainless steel operating table, and various tools and materials required for making fruit tea are usually equipped on its operating table. A discharging valve is installed on the barrel body of the heat preservation barrel 2. The main body of the nitrogen supply mechanism 3 is composed of a compressor, a converter, and a gas storage tank. Its main principle is that the compressor compresses air and then filters out nitrogen through the converter, and then the nitrogen enters the gas storage tank for storage. This is the prior art and will not be elaborated. The pipe valve mechanism 4 includes a pneumatic opening and closing valve and a pipeline;

[0029] In the actual use process, the pipeline transports the nitrogen in the gas storage tank to each heat preservation barrel. When the nitrogen in the corresponding heat preservation barrel 2 reaches the required amount, for example, when the air pressure in the heat preservation barrel reaches the preset value, the air pressure opening and closing valve will close at this time to block the nitrogen transportation, so as to keep the pressure inside the heat preservation barrel 2 greater than the external pressure. When the liquid material in the heat preservation barrel 2 is released through the discharge valve on the barrel body, the nitrogen in the heat preservation barrel provides power for the release of the liquid material at this time, maintaining a good discharge speed of the heat preservation barrel. In addition, the nitrogen can also play a role in preserving the freshness of the liquid material in the heat preservation barrel, which has good practical significance.

[0030] In another embodiment provided by the present invention, the pipe valve mechanism 4 includes a first pipe body 4.1 extending into the heat preservation barrel 2. The other end of the first pipe body 4.1 is connected and communicated with the nitrogen output end of the nitrogen supply mechanism 3. An air pressure opening and closing valve 4.3 is installed on the first pipe body 4.1;

[0031] In actual use, when the pressure difference between the two ends of the first pipe body 4.1 connected to the air pressure opening and closing valve 4.3 is less than the preset lower limit value of the valve body, the air pressure opening and closing valve 4.3 is in a closed state at this time. On the contrary, when the pressure difference between the two ends of the connected first pipe body 4.1 is greater than the preset upper limit value of the valve body, the air pressure opening and closing valve 4.3 is in an open state. The air pressure opening and closing valve 4.3 is an existing valve body, and its specific principle will not be elaborated;

[0032] In still another embodiment provided by the present invention, a piston assembly 5 is provided in the heat preservation barrel 2. The piston assembly 5 includes a piston plate 5.1. The plate surface of the piston plate 5.1 is perpendicular to the central axis of the heat preservation barrel 2. A core pipe 5.2 is fixedly penetrated through the middle of the piston plate 5.1. The core pipe 5.2 is a rigid pipe body. The central axis of the core pipe 5.2 coincides with the central axis of the heat preservation barrel 2. The top end of the core pipe 5.2 is inserted and connected with the first pipe body 4.1. The part of the first pipe body 4.1 inserted into the heat preservation barrel 2 is a straight rigid pipe body. The core pipe 5.2 can make telescopic movements in the vertical direction of the first pipe body 4.1. A base pipe 5.3 fixedly connected to the bottom of the heat preservation barrel 2 is movably sleeved at the bottom end of the core pipe 5.2. The base pipe 5.3 is a rigid pipe body. The core pipe 5.2 can make telescopic movements in the vertical direction of the base pipe 5.3. The piston assembly 5 can move vertically in the heat preservation barrel 2 under the action of air pressure; Preferably, a plurality of weight washers are provided on the piston plate 5.1, and the gravity of the piston plate 5.1 is adjusted by increasing or decreasing the number of weight washers;

[0033] Among them, a plurality of branch pipes 5.31 are fixedly communicated with the bottom side of the base pipe 5.3. The ends of each branch pipe 5.31 are blocking ends. A plurality of air leakage holes 5.32 are opened on the pipe body of the branch pipe 5.31;

[0034] In actual use, the first tube body 4.1 of the pipe-valve mechanism 4 introduces nitrogen into the core tube 5.2, which then guides the nitrogen into the base tube 5.3 and then flows through the various branch tubes 5.31 for diversion. Finally, it is dispersed into the liquid in the insulation barrel 2 through the vent holes 5.32. Since nitrogen is an inert gas, it does not chemically react with food and is not absorbed by food, and thus does not have any adverse effects on the liquid. The nitrogen then escapes from the upper part of the liquid in the insulation barrel 2. During the nitrogen escape process, the liquid is disturbed, thereby preventing the liquid in the insulation barrel 2 from sedimentation and maintaining a uniform state of the liquid.

[0035] As the nitrogen in the insulation barrel 2 increases, the air pressure between the piston assembly 5 and the bottom of the insulation barrel 2 increases, causing the piston assembly 5 to move upward in the vertical direction, thereby keeping the pressure in the insulation barrel 2 constant. In other words, as the material liquid in the insulation barrel 2 is released multiple times, the content of the material liquid in the insulation barrel 2 is different at different time periods. Since the pressure in the insulation barrel 2 is kept constant, when the insulation barrel 2 containing different capacities releases the material liquid in each time period, the discharge speed in each time period can be kept consistent, thereby maintaining the stability of the discharge process.

[0036] In another embodiment provided by the present invention, the branch pipe 5.31 includes a rubber hose 5.33, one end of which is connected to the base pipe 5.3 via a hard tube 5.34, and the other end of the rubber hose 5.33 is fixedly connected to a hard cylinder 5.35. The air leakage hole 5.32 is located on the hard cylinder 5.35. During the release process, due to the reaction force of the nitrogen airflow, the hard cylinder 5.35 will swing irregularly in the insulation barrel 2, thereby further increasing the degree of disturbance of the liquid material during the nitrogen escape process.

[0037] In another embodiment provided by the present invention, a gas valve unit 8 is installed on the plate body of the piston plate 5.1, and a resistance component 9 is provided above the piston plate 5.1. The resistance component 9 can open the gas valve unit 8 as the piston plate 5.1 rises;

[0038] Among them, the air valve unit 8 includes a sealing baffle 8.1 located at the bottom of the piston plate 5.1, the plate surface of the sealing baffle 8.1 is parallel to the bottom surface of the piston plate 5.1, and an elastic sealing ring 8.2 is fixed to the top of the sealing baffle 8.1. The sealing baffle 8.1 and the elastic sealing ring 8.2 can form a cover buckle area at the bottom of the piston plate 5.1. For example, when the sealing baffle 8.1 and the bottom surface of the piston plate 5.1 are squeezed against each other, the elastic sealing ring 8.2 is deformed between the sealing baffle 8.1 and the piston plate 5.1 to play a sealing role. The inner wall surface of the elastic sealing ring 8.2 is the boundary surface of the cover buckle area. A through hole 8.3 is opened on the cover buckle area of the piston plate 5.1. The through hole 8.3 can be adapted and plugged with the interference component 9. The center line of the through hole 8.3 is perpendicular to the sealing baffle 8.1, and the sealing baffle 8.1 and the piston plate 5.1 are connected by a tension spring 8.6;

[0039] Among them, the interference component 9 includes a straight rod 9.1, the straight rod 9.1 is located on the moving trajectory line of the through-hole 8.3, the axis of the straight rod 9.1 and the center line of the through-hole 8.3 are on the same vertical line, the straight rod 9.1 can pass through the through-hole 8.3, and an exhaust groove 9.2 is opened on the top side of the straight rod 9.1. The number of the exhaust grooves 9.2 can be selected to be multiple, the length direction of the exhaust groove 9.2 is consistent with the length direction of the straight rod 9.1, one end of the exhaust groove 9.2 is connected to the top of the straight rod 9.1, and the other end of the exhaust groove 9.2 is located on the side of the straight rod 9.1;

[0040] When the straight rod 9.1 has not yet come into contact with the sealing plate 8.1, the tension spring 8.6 is in its original length and contracted state. At this time, the elastic sealing ring 8.2 is squeezed and deformed between the sealing plate 8.1 and the piston plate 5.1. The formed cover buckle area seals and blocks the through-hole 8.3, preventing nitrogen from leaking from the bottom of the piston plate 5.1 to the area above the piston plate 5.1. At the same time, the lower end of the exhaust groove 9.2 is located in the through-hole 8.3. At this time, the air valve unit 8 is in a closed state.

[0041] During actual use, the piston assembly 5 moves upward in the vertical direction in the heat preservation barrel 2 under the action of air pressure. When the straight rod 9.1 contacts the sealing baffle 8.1 and a force is generated, at this time, the sealing baffle 8.1 moves downward, the tension spring 8.6 undergoes a tensile deformation, the distance between the sealing baffle 8.1 and the piston plate 5.1 increases, the elastic sealing ring 8.2 separates from the lower part of the piston plate 5.1, and the lower groove end of the exhaust groove 9.2 is located below the piston plate 5.1. At this time, the nitrogen gas below the piston plate 5.1 can enter the area above the piston plate 5.1 through the penetration port 8.3 and the exhaust groove 9.2, and at this time, the air valve unit 8 is in an open state; when the air pressure below the piston plate 5.1 decreases, then under the action of the gravity of the piston assembly 5, it moves downward in the vertical direction. When the straight rod 9.1 is completely separated from the sealing baffle 8.1, at this time, under the action of the elastic restoring force of the tension spring 8.6, the air valve unit 8 returns to the closed state. The above entire process achieves the effect of automatic pressure relief, which is beneficial to avoiding excessive pressure in the heat preservation barrel 2 and ensuring the normal use of the heat preservation barrel 2.

[0042] In another embodiment provided by the present invention, a sleeve 10 is fixed to the top of the piston plate 5.1, a rubber ring sleeve 11 is fixed to the inner wall surface of the sleeve 10, the rubber ring sleeve 11 is made of elastic rubber material, a ratchet tooth groove structure 12 is provided on the inner wall of the rubber ring sleeve 11, a convex structure 13 is provided on the side surface of the bottom end of the straight rod 9.1, the center line of the sleeve 10 coincides with the center line of the penetration port 8.3, and the tooth tip direction of the ratchet tooth groove structure 12 faces downward, thereby forming a barbed structure on the inner ring wall of the rubber ring sleeve 11. The convex structure 13 is preferably a plurality of hard rings fixedly sleeved on the straight rod 9.1;

[0043] During actual use, when the straight rod 9.1 approaches the sealing baffle 8.1, at this time, the straight rod 9.1 penetrates into the sleeve 10. During this process, the convex structure 13 slides over the ratchet tooth groove structure 12, and the resistance value between the convex structure 13 and the ratchet tooth groove structure 12 during this process is α. When the straight rod 9.1 contacts and then separates from the sealing baffle 8.1, it should be particularly noted that at this time, the straight rod 9.1 still contacts the sealing baffle 8.1, and the air valve unit 8 has not been closed. At this time, the straight rod 9.1 moves away from the sleeve 10. During this process, the convex structure 13 and the ratchet tooth groove structure 12 are engaged to form a resistance to detachment, and the resistance value between the convex structure 13 and the ratchet tooth groove structure 12 during this process is β, and β is greater than α, thereby hindering the detachment movement of the straight rod 9.1 at this stage, and the air valve unit 8 remains in the open state. As the air pressure below the piston plate 5.1 continues to decrease, the supporting force on the piston plate 5.1 decreases. Then when the resistance to detachment is less than the gravity of the piston assembly 5, at this time, the straight rod 9.1 can be completely separated from the sealing baffle 8.1;

[0044] During the whole process, it achieves the effect of automatically delaying the closing of the air valve unit 8, thereby improving the automatic pressure relief effect.

[0045] In another embodiment provided by the present invention, a bucket lid 6 is adapted to the top of the heat preservation bucket 2. The bottom of the bucket lid 6 is perpendicularly fixed to the straight rod 9.1. The first pipe body 4.1 is fixedly penetrated through the middle of the bucket lid 6. An exhaust hole 7 is formed in the bucket lid 6. The exhaust hole 7 can release the excess nitrogen in the area above the piston plate 5.1 to the outside of the heat preservation bucket 2. It should be further noted that when the bucket lid 6 and the heat preservation bucket 2 are closed, they are connected by a locking member. The locking member can be selected as a rotary lock, a bolt lock or a flip lock, etc., so that the bucket lid 6 can be tightly closed on the heat preservation bucket 2. Further, an iron sheet 16 is fixed to the bottom of the heat preservation bucket 2, thereby increasing the wear resistance of the bottom surface of the heat preservation bucket 2;

[0046] It should be particularly noted that a magnetic attraction seat 14 is fixed on the table body 1, and a switching handle 15 is provided on the magnetic attraction seat 14. In actual use, the heat preservation bucket 2 is adsorbed and fixed to the magnetic attraction seat 14, thereby improving the stability of the heat preservation bucket 2 when placed on the table body 1. When it is necessary to remove the heat preservation bucket 2 from the table body 1, at this time, the switching handle 15 is toggled so that the magnetic attraction force of the magnetic attraction seat 14 on the heat preservation bucket 2 is cancelled. It should be particularly noted that the first pipe body 4.1 can be connected and rotated at the nitrogen output end of the nitrogen supply mechanism 3. When the heat preservation bucket 2 is translated away from the magnetic attraction seat 14, the heat preservation bucket 2 can be removed. The whole process is simple to operate and is convenient for the disassembly and fixing of the heat preservation bucket 2 on the table body 1.

[0047] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
