Description

Technical Field

[0001] This utility model relates to the field of tea machinery technology, and in particular to a small manual tea opener. Background Technology

[0002] Many dark tea products are compressed into tea bricks to reduce the volume of the tea leaves, making them easier to transport and store. More importantly, aging allows them to develop a better flavor. Because these tea bricks are compressed, they are difficult to break into smaller, more manageable pieces for precise brewing. While tea manufacturers could utilize automated, continuously crushing machinery to pre-break down whole tea bricks into smaller, more manageable pieces for controlled brewing, packaging these smaller bricks for sale, these machines are bulky, cumbersome, require significant space, have high throughput, and pose safety risks. They also require professional operation, making them unsuitable for retail stores or individual tea-breaking. Currently, there is no easily operable, portable tea-breaking device available for retail stores to offer customers a brick-breaking service, enhancing their experience, or for home tea enthusiasts to enjoy themselves. In reality, stores and individuals can only use small tools like tea tongs or tea knives to break the tea bricks. However, this brick-breaking and tea-opening process requires a high level of physical strength from the operator and is relatively easy to cause accidental injury. Furthermore, this operation can easily cause tea fragments to scatter everywhere, and the size and shape of the small brick fragments are difficult to control. The brick-breaking process is time-consuming, labor-intensive, lacks safety, and results in a certain amount of tea loss.

[0003] Currently, more and more tea brick and tea cake manufacturers are paying attention to the difficulties faced by consumers of compressed tea products, and many have developed devices specifically for opening brick tea. Summarizing the tea-opening devices that can be found in the past, they can be roughly divided into the following methods: saw blade cutting, blade cutting, stamping and cutting into blocks, needle piercing and dismantling, etc., and some even use a combination of methods for dismantling.

[0004] An electric tea-opening device, authorized by publication number CN206674930U (patent application number 201720345594.9), uses an electric cutter for tea bricks. It features a degree of automation and is a sealed tea-opening device. Another similar utility model patent, publication number CN203985901U (patent application number 201420397711.2), discloses a compressed tea-cutting machine. This machine uses a moving saw blade to cut compressed tea (thousand-liang tea) into tea cakes or into small tea pieces. A common advantage of these saw-blade-based tea-opening devices is that the resulting tea pieces are neatly shaped bricks with pre-defined sizes and shapes, and there are few restrictions or requirements on the shape of the compressed tea being opened. However, their common disadvantages are significant tea loss and the large amount of heat generated during sawing, which significantly affects the quality of the tea around the cut edge.

[0005] The utility model patent with patent publication number CN202525010U (patent application number 201220091814.7) describes a tea-opening device that uses a screw with a pressure head moving relative to a bottom support / collection box with a bottom cutter to open compressed Pu-erh tea—Tuocha. The opening process is essentially a forceful cut. The utility model patent with patent publication number CN203496049U (patent number CN201320657342.1) discloses a tea-slicing machine. It uses a four-bar linkage mechanism that leverages the lever principle to drive the blades in reciprocating motion, thus cutting the block-shaped Pu-erh tea into pieces. Both of these tea-opening devices are only suitable for loosely compressed tea cakes like Pu-erh tea, and cannot be used for opening compressed teas. Furthermore, the blades become dull after repeated use, and frequent blade cleaning is a tedious process.

[0006] An automated tea-breaking device for compressed tea, with authorization announcement number CN210642250U (application number 201821896505.0), is disclosed. The design utilizes a needle-shaped splitting device, including a pointed needle structure, a fixing component, and a power mechanism. The pointed needle structure is vertically mounted on the same side of the fixing component in a comb-like shape, and the fixing component is mounted on the power mechanism. The device uses a needle-point impact method to break the tea brick. This design places high demands on the needle's design, and the mechanism is quite complex. A brick tea splitting device published in patent publication number CN105875889A (application number 201610385305.8) uses microwave heating to quickly soften the brick tea, then uses arrow-shaped needles to impact and pierce the side of the tea brick, causing the interior to crack naturally. Finally, a cutting device breaks the brick tea into small pieces. Although the combination of the arrow-shaped striking pin and microwave heating in this device can make it easier to crack tea bricks, it has the following drawbacks: (1) After cracking, the shape of the tea brick is not uniform, and the damage marks on the denser tea bricks pierced by the arrow-shaped striking pin are still large, with more broken pieces; (2) This device requires microwave heating to assist in tea dismantling, which affects the internal quality of the tea; using a saw blade to cut small pieces results in a large loss of tea material; (4) Moreover, the structure is relatively complex, energy consumption is high, and maintenance is inconvenient.

[0007] The patent with publication number CN204560811U (application number CN201520110114.1) uses an impact method to break compressed tea cakes or bricks into pieces. The pressing heads include active and passive heads arranged alternately on a pressure plate. The passive heads are mounted on the pressure plate via buffer springs. The active and passive heads exert the same magnitude but opposite directions of force on the compressed tea cakes or bricks. The advantages of this design are fast tea-breaking speed and uniform tea pieces size. The disadvantages are that the tea bricks should not be too thick, otherwise successful pressing is difficult; to ensure successful pressing, the resulting bricks are relatively large; and regardless of the brick thickness, the resulting individual bricks are all the same size; different sizes and shapes of bricks require corresponding sizes and shapes of pressing heads. This equipment is relatively large, complex in structure, and expensive, making it suitable for batch tea-breaking in production plants but not for use in retail stores.

[0008] These previous patented inventions reveal that while significant progress has been made in addressing the pain points of tea opening and numerous solutions have been proposed, truly effective designs for tea opening devices specifically designed for compressed tea bricks are still limited. Particularly concerning are the miniaturization, simplification, durability, and ease of maintenance of these devices. There is still a considerable distance to go before tea opening devices are suitable for both retail stores and home use. Therefore, developing a portable tea opener that is suitable for use in stores, by tea enthusiasts at home, and even easily operated by women with limited strength is essential. Utility Model Content

[0009] This utility model provides a small manual tea opener, which aims to solve the problem mentioned above of the lack of small tea openers that are labor-saving, portable and convenient.

[0010] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A small manual tea opener includes a main body, the bottom of which is supported and suspended on an operating platform by a support assembly. The main body is divided into a tea brick box and a piercing box by a partition. Tea bricks are placed in the tea brick box with pads to elevate them. A brick-breaking piercing assembly is movably installed in the piercing box. A rotatable pressing assembly is provided on the side of the piercing box away from the tea brick box. A side strip box is provided on the side of the tea brick box away from the piercing box. A breaking assembly is provided at the bottom of the side strip box. When the pressing component presses down, it is linked with the brick-breaking bayonet component. The brick-breaking bayonet component slides towards the tea brick box and passes through the access window on the partition to pierce the top of the tea brick in the tea brick box to break the brick. After the broken brick is removed, the top layer of the tea brick is inserted into the breaking component to apply external force to break it.

[0011] Preferably, the top of the side box near the tea brick box has an opening that communicates with the top of the tea brick box, and the size of the opening is not smaller than the size of the entrance window. The top of the side box is sealed by a cover plate.

[0012] Preferably, the brick-breaking bayonet assembly includes an L-shaped bayonet holder, the horizontal part of which is embedded in the bayonet box to form a sliding fit along the extension direction of the bayonet box, the vertical part of which is parallel to the partition, and a number of bayonets are equally spaced on one side of the top of the vertical part along the extension direction of the entrance window. All bayonets are arranged horizontally and simultaneously penetrate the entrance window.

[0013] More preferably, the ends of the bayonets are all pointed, and the bayonets form a limiting fit with the access window to prevent them from tilting up. The bayonets are all detachably fixed to the vertical part of the bayonet holder.

[0014] Preferably, the pressing assembly includes a push rod, and the bayonet box is provided with an installation chamber on the side away from the tea brick box. A rotating shaft is provided in the installation chamber, and one end of the push rod forms a rotational engagement with the rotating shaft around the rotating shaft. The side of the side bar box away from the bayonet box is fixedly installed with a vertically arranged pressure rod bracket by fasteners. The pressure rod bracket is provided with a limiting groove arranged in the vertical direction, and the top of the limiting groove is open. The other end of the pushing pressure rod is movably embedded in the limiting groove from the opening to form a limiting fit.

[0015] More preferably, the push rod is elastically rotated with the rotating shaft through a torsion spring. In the initial position, the push rod is kept tilted up by the torsion spring, and the torsion spring enters an energy storage state when it is pressed down.

[0016] More preferably, the linkage component includes a toothed plate disposed on the side of the brick-breaking bayonet assembly away from the tea brick box, and a top plate is hinged to the bottom side of the push rod. When pressed down, the top plate and the toothed plate form a limiting engagement and push the toothed plate to slide toward the tea brick box, and the brick-breaking bayonet assembly and the toothed plate form a synchronous linkage.

[0017] Preferably, the breaking assembly includes a breaking frame located at the bottom of the side box, with a horizontally arranged breaking plate inside the breaking frame on the side away from the bayonet box. The breaking plate does not block the breaking frame. The breaking frame above the breaking plate has an opening that cooperates with the breaking plate to form a breaking window. A vertically arranged baffle is located inside the breaking frame on the side near the bayonet box. The baffle is opposite to the breaking window. After the tea brick is inserted into the breaking window, it abuts against the baffle and is broken by the tea brick in cooperation with the breaking plate and the breaking window under the action of external force.

[0018] Preferably, the bottom of the brick-breaking bayonet assembly is limited to slide against the bayonet box by an anti-tilting component, which is used to prevent the brick-breaking bayonet assembly from tilting up.

[0019] More preferably, the anti-tilting component includes a strip-shaped hole at the bottom of the bayonet box. The extension direction of the strip-shaped hole is consistent with the sliding direction of the brick-breaking bayonet component. The bottom of the brick-breaking bayonet component is provided with a slider that passes through the strip-shaped hole. The slider slides along the strip-shaped hole and forms a sliding fit with the strip-shaped hole. After the slider passes through the strip-shaped hole, an anti-tilting plate is detachably fixed by several fastening screws. The top of the anti-tilting plate is close to the bottom of the bayonet box.

[0022] The embodiments will be further described below with reference to the accompanying drawings.

[0023] like Figures 1-6 As shown, in a preferred embodiment 1, the bottom of the main box 1 is supported and suspended on the operating platform by the support component 7. The main box 1 is divided into a tea brick box 102 and a bayonet box 103 by a partition 104. Tea bricks are placed in the tea brick box 102 by padding blocks. A brick-breaking bayonet component 2 is movably installed in the bayonet box 103. A rotatable pressing component 4 is provided on the side of the bayonet box 103 away from the tea brick box 102. A side strip box 101 is provided on the side of the tea brick box 102 away from the bayonet box 103. A breaking component 6 is provided at the bottom of the side strip box 101. When the pressing component 4 presses down, it is linked with the brick-breaking bayonet component 2 through the linkage component 5. The brick-breaking bayonet component 2 slides toward the tea brick box 102 and passes through the inlet and outlet window 105 on the partition 104 to pierce the top of the tea brick in the tea brick box 102 to break the brick. After the broken brick is removed, the top layer of the tea brick is inserted into the breaking component 6 to apply external force to break it.

[0024] When in use, press down the pressing component 4. When the pressing component 4 is pressed down, it is linked with the brick-breaking bayonet component 2 through the linkage component 5. The brick-breaking bayonet component 2 slides toward the tea brick box 102 and passes through the inlet and outlet window 105 on the partition 104 to pierce the top of the tea brick in the tea brick box 102 to break the brick. After breaking the brick once, lift the pressing component 4 to the initial position, manually restore the brick-breaking bayonet component 2 to the initial position, and then use the linkage component 5 to make the pressing component 4 and the brick-breaking bayonet component 2 re-link. Repeat the above steps multiple times until the brick breaking is completed. After the tea brick is broken, the pieces usually cannot be completely separated, as they are still connected by ribs. However, they are easier to separate. Tear off the thin pieces of the broken brick and insert them into the breaking component 6. Apply vertical shearing force to break the thin pieces of the brick into small pieces within the breaking component 6. When it is necessary to break the brick again, a shim needs to be added to raise the remaining tea brick so that its bottom reaches the set height again for breaking. Repeat the above steps to complete the brick breaking.

[0025] Preferably, the side box 101 is a long, narrow box with a closed top and an open side top. It is located at the front of the main box 1 and its function is to strengthen the structural strength of the main box 1, provide support for receiving broken tea bricks, and provide buffer space for the advance of the brick-breaking bayonet. Tea brick box 102 is a place to place tea bricks to be broken. It is an open rectangular flat box. One side of the box has a brick-breaking bayonet that can be pushed in to split the tea brick laterally. The other side provides support for the tea bricks to be broken. One end of the bottom plate of the box has a round hole for lifting the tea bricks or pads inside the box with your fingers to facilitate the removal of items. The bayonet box 103 is where the knife holder assembly for breaking and splitting tea bricks is installed. It consists of three interconnected chambers. The first chamber is the first chamber where the brick-breaking bayonet assembly 2 and the toothed plate 501 slide. The second chamber is the second chamber where the toothed plate 501 is limited to slide. The third chamber is the third chamber where the push rod 401 is installed. During the pressing process, part of the push rod 401 may enter the second chamber.

[0026] As a preferred embodiment 2, the top of the side strip box 101 near the tea brick box 102 has an opening that communicates with the top of the tea brick box 102, and the size of the opening is not less than the size of the access window 105, so that the bayonet 202 can also enter, and push the top layer of the broken tea brick into the opening, so that it enters the breaking assembly 6 along the side strip box 101. The top of the side strip box 101 is sealed by a cover plate, which ensures that the material is always conveyed downwards.

[0027] As a preferred embodiment 3, the brick-breaking bayonet assembly 2 includes an L-shaped blade holder 201. The horizontal part of the blade holder 201 is embedded in the bayonet box 103 to form a sliding fit along the extension direction of the bayonet box 103. The vertical part of the blade holder 201 is parallel to the partition 104. A plurality of bayonets 202 are equally spaced on one side of the top of the vertical part along the extension direction of the access window 105. All bayonets 202 are arranged horizontally and simultaneously penetrate the access window 105.

[0028] The ends of the bayonets 202 are all pointed, and the bayonets 202 and the access window 105 form a limiting fit to prevent them from tilting up. The bayonets 202 are all detachably fixed to the vertical part of the bayonet holder 201.

[0029] Preferably, the knife holder 201 can be made of L-shaped angle iron, with the horizontal part used for sliding and the vertical part used for mounting the bayonet 202; The bayonet 202 used for breaking bricks is a sword-shaped bayonet, with 5 to 7 bayonets. The front conical section of the bayonet 202 is sharpened on both sides with the blades facing downwards, ensuring that the bayonet 202 can move forward horizontally and that the blades do not curl up. At the same time, the downward-facing blade also helps the thin brick pieces above the bayonet to be lifted upwards and peeled off from the main body of the tea brick below when the bayonet is pushed forward. The distance between the lower surface of the brick-breaking bayonet 202 and the bottom plate of the box is 2.4cm. The thickness of a typical tea brick is 2.5-3.2cm. It is estimated that the thin brick piece formed after the first split will be between 6-8mm. The remaining thickness is about 2.4cm, which is exactly a multiple of 8mm. When splitting bricks later, an 8mm thick bakelite or silicone sheet can be placed under the tea brick to be split to make the thin brick piece that is split off reach the ideal thickness (6-8mm). This thickness of brick piece makes it easier to break by hand later. Secondly, the length of the bayonet 202 needs to be sufficient to penetrate into the side box 101, so that the tea brick piece to be broken can be completely inserted into the side box 101.

[0030] As a more preferred embodiment 4, the vertical part of the knife holder 201 is provided with a mounting hole for mounting the bayonet 202. The bayonet 202 is provided with a mounting seat at the end away from the blade. After the bayonet 202 passes through the mounting hole, the mounting seat is fixedly installed to the vertical part of the knife holder 201 by fasteners, which ensures the installation stability and facilitates replacement and disassembly.

[0031] As a preferred embodiment 5, the pressing component 4 includes a push rod 401, and the bayonet box 103 is provided with an installation chamber on the side away from the tea brick box 102. The installation chamber is provided with a rotating shaft 402, and one end of the push rod 401 forms a rotational engagement with the rotating shaft 402 around the rotating shaft 402. A vertically arranged pressure rod bracket 404 is fixedly installed on the side of the side bar box 101 away from the bayonet box 103 by fasteners. The pressure rod bracket 404 is provided with a limiting groove 405 arranged in the vertical direction, and the top of the limiting groove 405 is open. The other end of the pushing pressure rod 401 is movably embedded in the limiting groove 405 from the opening to form a limiting fit.

[0032] The linkage component 5 includes a toothed plate 501 located on the side of the brick-breaking bayonet assembly 2 away from the tea brick box 102. A top plate 502 is hinged to the bottom side of the push rod 401. When pressed down, the top plate 502 and the toothed plate 501 form a limiting engagement and push the toothed plate 501 to slide toward the tea brick box 102. The brick-breaking bayonet assembly 2 and the toothed plate 501 form a synchronous linkage.

[0033] The installation chamber is the third chamber described in Example 1. The limiting groove 405 of the pressure rod bracket 404 ensures that the movement direction of the push rod 401 is vertical up and down. The other side of the push rod 401 rotates around the axis 402. When the push rod 401 rotates downward, it achieves downward pressure. The toothed plate 501 is welded and fixed to the horizontal part of the tool holder 201. When the push rod 401 is pressed down, the push plate 502 pushes the tool holder 201 forward with the help of the toothed plate 501. Using the toothed plate 501 has another advantage: the first few times you break the brick, you may not be able to break it all the way through. The dagger 202 needs to use multiple downward presses to break the brick continuously. At this time, when you can no longer continue to pierce smoothly, you can lift the top push rod 401, align the top plate 502 with other tooth grooves away from the direction of the tea brick box 102, and press down again. By repeatedly pressing down and lifting the top push rod 401, the top plate 502 will continuously push the knife holder 201 forward, thereby pushing the brick-breaking dagger 202 to chop into the tea brick step by step until it reaches the top, and finally complete the action of splitting the whole tea brick. Once the knife holder 201 reaches its top, fully lift the push rod 401 so that the push rod 502 is completely disengaged from the tooth plate 501. The knife holder 201 is no longer restricted. At this point, the knife holder 201 can be pulled back to its initial position, and the push rod can be put back. Select the appropriate tooth groove limiting top plate 502 to complete the preparation for the second tea brick breaking.

[0034] When in use, it is generally ensured that the angle between the top plate 502 and the toothed plate 501 on the side away from the tea brick box 102 is greater than 90°, so that when the push rod 401 is pressed down, the side of the top plate 502 away from the hinge tends to move forward, pushing the toothed plate 501 towards the side of the tea brick box 102.

[0035] As a more preferred embodiment 6, the push rod 401 forms an elastic rotational engagement with the rotating shaft 402 through the torsion spring 403. In the initial position, the push rod 401 is kept tilted up by the torsion spring 403. When pressed down, the torsion spring 403 enters the energy storage state, which facilitates the return to the initial position and provides a reaction force to ensure the stability during pressing down and further improve the pressing performance. A second torsion spring can also be used on the hinge shaft of the top plate 502 to form an elastic rotation. When pressed down, the top plate 502 pushes forward, and the second torsion spring enters an energy storage state to provide a reaction force, ensuring stability when pressed down and further improving the forward pushing performance.

[0036] As a preferred embodiment 7, the breaking assembly 6 includes a breaking frame 601 at the bottom of the side box 101. A horizontally arranged breaking plate 603 is provided inside the breaking frame 601 on the side away from the bayonet box 103. The breaking plate 603 does not block the breaking frame 601, making it convenient to take out the small thin piece from the bottom or push it out from the breaking window 604. The breaking frame 601 above the breaking plate 603 has an opening that cooperates with the breaking plate 603 to form the breaking window 604. A vertically arranged baffle 602 is provided inside the breaking frame 601 on the side near the bayonet box 103. The baffle 602 is opposite to the breaking window 604. After the tea brick is inserted into the breaking window 604, it abuts against the baffle 602 and is broken by external force in cooperation with the breaking plate 603 and the breaking window 604.

[0037] The breaking assembly 6 is located under the side box and consists of a thin brick breaking frame 601, a breaking plate 603, and a baffle 602. The breaking frame 601 above the breaking plate 603 has an opening that cooperates with the breaking plate 603 to form a breaking window 604 opposite to the baffle 602. When breaking, the thin brick is inserted into the breaking window 604 and abuts against the baffle 602 along the breaking plate 603, so that the broken part is almost a constant length. An upward or upward shearing force is applied to the part outside the breaking window 604, which works together with the breaking window 604 and the breaking plate 603 to break the brick.

[0038] Preferably, the baffle 602 is about 3cm away from the break-off window 604, limiting the length of the thin brick piece inserted into the break-off window 604 to only about 3cm. This results in a broken thin brick strip with a width of only about 3cm. The tea brick, after being cut, has a width of about 3cm and a thickness of about 0.8cm. Thus, the small thin brick pieces broken off from the thin brick strip are approximately 3cm × 3cm × 0.8cm in size. This size of small tea brick is suitable for brewing a single serving for several people and facilitates breaking the brick to a fixed length.

[0039] In a preferred embodiment 8, the bottom of the brick-breaking bayonet assembly 2 is limited and slidably connected to the bayonet box 103 by an anti-tilting component 3 to prevent the brick-breaking bayonet assembly 2 from tilting up. This ensures the direction of sliding and prevents tilting.

[0040] As a more preferred embodiment 9, the anti-tilting component 3 includes a strip hole 301 at the bottom of the bayonet box 103. The extending direction of the strip hole 301 is consistent with the sliding direction of the brick-breaking bayonet component 2. The bottom of the brick-breaking bayonet component 2 is provided with a slider 302 that passes through the strip hole 301. The slider 302 forms a sliding fit with the strip hole 301 along the strip hole 301. After the slider 302 passes through the strip hole 301, an anti-tilting plate 303 is detachably fixed by a number of fastening screws 304. The top of the anti-tilting plate 303 is close to the bottom of the bayonet box 103.

[0041] It facilitates disassembly and replacement. The anti-tilting plate 303 prevents the tool holder 201 from tilting up, and the slider 302 ensures the sliding direction.

[0042] As a preferred embodiment 10, the support component 7 includes support legs 701 and pads 702. There are four support legs 701 distributed symmetrically in pairs at the bottom of the main box 1. All support legs 701 are arranged vertically to ensure the suspension support of the main box 1. The pads 702 increase the force-bearing area and ensure the stability of the support.

[0043] The working principle of this utility model: When in use, press down the pressing component 4. When the pressing component 4 is pressed down, it is linked with the brick-breaking bayonet component 2 through the linkage component 5. The brick-breaking bayonet component 2 slides toward the tea brick box 102 and passes through the inlet and outlet window 105 on the partition 104 to pierce the top of the tea brick in the tea brick box 102 to break the brick. After breaking the brick once, lift the pressing component 4 to the initial position, manually restore the brick-breaking bayonet component 2 to the initial position, and then use the linkage component 5 to make the pressing component 4 and the brick-breaking bayonet component 2 re-link. Repeat the above steps multiple times until the brick breaking is completed. After the tea brick is broken, the pieces usually cannot be completely separated, as they are still connected by ribs. However, they are easier to separate. Tear off the thin pieces of the broken brick and insert them into the breaking component 6. After the breaking window 604 is inserted, it presses against the baffle 602 and applies a vertical shearing force. This, together with the breaking plate 603 and the first-level breaking window 604, breaks the thin brick into a small thin brick within the breaking frame 601. After removing the small thin brick, continue inserting and breaking. Repeating the above operation can break the tea brick into small thin bricks of almost equal length. When it is necessary to break the brick again, a shim needs to be added to raise the remaining tea brick so that its bottom reaches the set height again for breaking. Repeat the above steps to complete the brick breaking.
