Abstract
Description
Technical Field
[0001] This utility model relates to the field of locking device technology, and in particular to a locking device for a pressurized brewing machine. Background Technology
[0002] In today's fast-paced life, tea capsules, with their convenience, precise dosage, and stable flavor, greatly satisfy people's demand for high-quality tea drinks anytime, anywhere. As a result, pressurized tea capsule brewing machines have become increasingly popular. These machines efficiently extract tea from capsules by injecting high-pressure water into a sealed chamber. This not only quickly enhances the deep aroma of the tea leaves and fully releases their effective components, but also significantly shortens brewing time, providing users with a rich and mellow tea drinking experience.
[0003] However, with the increasing variety of usage scenarios and frequency of use, pressurized tea capsule brewing machines have revealed some problems that cannot be ignored during actual operation. When brewing tea capsules, a high-pressure environment quickly forms inside the brewing machine, which can easily cause the lid to be forced open by the strong pressure. Once the lid is opened, the high-pressure hot water carrying tea residue will splash everywhere, not only scalding the user but also potentially damaging the surrounding environment, posing a serious safety hazard. At the same time, the instantaneous release of pressure during brewing disrupts the originally stable extraction environment, preventing the tea capsules from being fully extracted, severely affecting the taste and quality of the tea.
[0004] Existing pressure brewing machine lid locking devices are often overly complex in structure, which not only increases production costs and manufacturing difficulty but also causes many inconveniences for later maintenance and upkeep. Therefore, this utility model proposes a pressure brewing machine lid locking device. Utility Model Content

Positioning pieces are respectively fixedly connected to both ends of the sliding rod. The opposite sides of the two groups of positioning pieces are respectively in contact with the two groups of fixing plates.
[0009] Optionally, the triggering component includes a connecting plate fixedly connected to the side of the sliding rod close to the fixing block. The connecting plate penetrates through the clamping block and is slidably matched with it. An inclined rack is fixedly connected to the side of the connecting plate away from the sliding rod. A moving plate is fixedly connected to the end of the inclined rack away from the connecting plate. The top of the moving plate penetrates through the sealing cover and a pushing plate is installed. The moving plate is slidably matched with the sealing cover.
[0010] Optionally, a first limiting rod is fixedly connected to the side of the moving plate away from the inclined rack. A limiting piece is slidably connected to the first limiting rod. The limiting piece is fixedly connected to the bottom wall of the sealing cover.

[0033] Example
[0034] like Figures 1 to 3 As shown, this utility model proposes a pressurized tea brewing machine lid locking device, including a tea brewing machine body 1. The top of the tea brewing machine body 1 is provided with a placement groove 11, which is used to support tea capsules. This placement groove 11 is specifically designed to support tea capsules. When brewing, the user only needs to accurately place the tea capsule in the placement groove 11 to start the brewing process.
[0035] Furthermore, the aforementioned locking device includes a sealing cap 2 rotatably connected to the placement groove 11. The sealing cap 2 is hollow and is used to press against the placement groove 11 to achieve a seal. This effectively creates a relatively sealed brewing space, preventing high-pressure steam and hot water from overflowing during the brewing process, ensuring the stability of the tea capsule extraction environment, and allowing the aroma and active ingredients of the tea capsule to be fully released in the closed environment, significantly improving the quality of the tea infusion.
[0036] For details, please refer to Figures 2 to 5 The aforementioned locking device also includes a locking mechanism 3 disposed between the placement groove 11 and the sealing cap 2. The locking mechanism 3 is used to lock the sealing cap 2 onto the placement groove 11. The locking mechanism 3 includes a latching block 31 slidably connected to the bottom of the sealing cap 2. The latching block 31 is L-shaped. A fixing block 32 that cooperates with the latching block 31 is fixedly connected to the side of the sealing cap 2. The fixing block 32 is "U"-shaped. When the latching block 31 slides to engage with the fixing block 32, it can effectively prevent the sealing cap 2 from rotating and opening at will. This not only ensures the sealing of the brewing space but also avoids the sealing cap 2 from accidentally opening due to excessive brewing pressure, greatly reducing the risk of burns and improving safety during use. Furthermore, an arc-shaped groove 36 is provided on the opening side of the fixing block 32, which facilitates the latching block 31 to slide and engage with the fixing block 32. The locking mechanism 3 also includes a sliding rod 33 slidably connected to the locking block 31. Under the limiting action of the sliding rod 33, the locking block 31 can move up and down precisely, thus more easily locking into the fixed block 32. Two sets of fixing plates 34 are slidably connected to the sliding rod 33. The two sets of fixing plates 34 are symmetrically arranged on both sides of the locking block 31. Both sets of fixing plates 34 are fixedly connected to the bottom wall of the sealing cover 2. The fixing plates 34, by virtue of their fixed positions, work with the sliding rod 33 to limit the movement of the locking block 31, ensuring that the locking block 31 remains stable during movement and avoiding shaking or jamming, further improving the reliability of locking. Positioning pieces 35 are fixedly connected to both ends of the sliding rod 33. The opposite sides of the two sets of positioning pieces 35 are respectively in contact with the two sets of fixing plates 34. The limiting action of the positioning pieces 35 ensures that the sliding rod 33 is always stably located inside the locking block 31, continuously and effectively limiting the movement of the locking block 31.
[0037] Furthermore, the aforementioned locking device includes a trigger assembly 4 mounted on the locking mechanism 3, which is used for locking operations. The trigger assembly 4 includes a connecting plate 41 fixedly connected to the sliding rod 33 near the fixed block 32. The connecting plate 41 passes through the locking block 31 and slides with it. A helical rack 42 is fixedly connected to the side of the connecting plate 41 away from the sliding rod 33. A moving plate 43 is fixedly connected to the end of the helical rack 42 away from the connecting plate 41. When the moving plate 43 moves, it drives the sliding rod 33 to move synchronously via the helical rack 42 and the connecting plate 41, thereby moving the locking block 31 and enabling the locking block 31 to be easily engaged with the fixed block 32. A push plate 44 is mounted on the top of the moving plate 43, passing through the sealing cover 2. The moving plate 43 slides with the sealing cover 2. The design of the push plate 44 greatly facilitates the user in moving the moving plate 43 by pushing the push plate 44, significantly improving the ease of operation. A first limiting rod 45 is fixedly connected to the side of the movable plate 43 away from the helical rack 42. The first limiting rod 45 moves synchronously with the movable plate 43. A limiting piece 46 is slidably connected to the first limiting rod 45. The limiting piece 46 is fixedly connected to the bottom wall of the sealing cover 2. The limiting piece 46 and the first limiting rod 45 work together to limit the movable plate 43, ensuring that the movable plate 43 remains stable during movement and preventing deviation or tilting. A first spring 47 is sleeved on the outer ring of the first limiting rod 45. The first spring 47 is located between the movable plate 43 and the limiting piece 46. Through the setting of the first spring 47, during the movement of the movable plate 43, the first spring 47 is compressed and stores elastic potential energy. When it is necessary to unlock, the first spring 47 can release the stored elastic force, driving the movable plate 43 to automatically reset, realizing the automation of locking and unlocking operations and further simplifying the user operation process. The first limiting rod 45 is fixedly connected to the first limiting plate 48 at the end away from the moving plate 43. The setting of the first limiting plate 48 effectively prevents the first limiting rod 45 from disengaging from the limiting piece 46, ensuring that the entire trigger assembly 4 is always in a stable working state.
[0038] Furthermore, the aforementioned locking device also includes a limiting mechanism 5 mounted on the locking mechanism 3. The limiting mechanism 5 is used to lock and unlock. The limiting mechanism 5 includes two sets of second limiting rods 51 fixedly connected to the bottom wall of the sealing cover 2. The two sets of second limiting rods 51 are symmetrically arranged on both sides of the helical rack 42. Mounting pieces 52 are slidably connected to the two sets of second limiting rods 51. Since the positions of the second limiting rods 51 are fixed, the mounting pieces 52 can remain stable during movement, avoiding shaking or displacement. A helical tooth block 53 that cooperates with the helical rack 42 is mounted at the bottom of the mounting piece 52. The helical tooth block 53 allows the helical rack 42 to move away from the locking block 31, while preventing the helical rack 42 from moving closer to the locking block 31. This design ensures that after the locking block 31 successfully engages with the fixing block 32, the helical tooth block 53 can prevent the locking block 31 from disengaging from the fixing block 32, effectively improving the stability and reliability of the locking. A second limiting plate 54 is fixedly connected to the top of the second limiting rod 51. A second spring 55 is sleeved on the outer ring of the second limiting rod 51 and is located between the mounting plate 52 and the second limiting plate 54. When the helical tooth block 53 needs to separate from the helical rack 42, the second spring 55 can release its elastic force, pushing the mounting plate 52 to move the helical tooth block 53 closer to the helical rack 42, thereby re-limiting the helical rack 42. A pull rod 56 is fixedly connected to the top of the mounting plate 52. One end of the pull rod 56 passes through the sealing cover 2 and is fixedly connected to a pull ring 57. The user only needs to pull the pull ring 57 to move the mounting plate 52 through the pull rod 56, thereby causing the helical tooth block 53 to release its limitation on the helical rack 42. At this time, the first spring 47 releases its elastic force, thereby resetting the locking block 31 and achieving the purpose of unlocking. The operation is simple and convenient, greatly improving the user experience.
[0039] In this embodiment, the user places the tea capsule in the placement slot 11 on the top of the tea brewing machine body 1. The placement slot 11 provides stable support for the tea capsule, thus preparing it for brewing. The sealing cover 2, which is rotatably connected to the placement slot 11, is pressed down into the placement slot 11. The sealing cover 2 can create a relatively sealed brewing space, preventing high-pressure steam and hot water from overflowing during brewing.
[0040] The user pushes the push plate 44 on top of the sealing cover 2, which drives the moving plate 43 to move. The moving plate 43, through the helical rack 42 and the connecting plate 41, drives the sliding rod 33 to move, which in turn drives the locking block 31 to slide. The locking block 31 slides along the arc-shaped groove 36 on one side of the opening of the fixing block 32 and locks into the fixing block 32, thereby locking the sealing cover 2 onto the placement groove 11. During the movement of the locking block 31, the sliding rod 33, under the limiting action of the two sets of fixing plates 34 and the positioning piece 35, smoothly drives the locking block 31 to move, ensuring the stability of the locking process. When the moving plate 43 moves, the first limiting rod 45 moves smoothly under the limiting action of the limiting piece 46, while simultaneously compressing the first spring 47 to store elastic potential energy. At the same time, under the action of the helical rack 53, the helical rack 42 is prevented from moving closer to the locking block 31, thereby preventing the locking block 31 from disengaging from the fixing block 32.
[0041] Once the sealing cap 2 is locked, the tea maker starts. During the brewing process, the sealed brewing space maintains a stable pressure environment, allowing the aroma and active ingredients of the tea capsules to be fully released, thereby improving the quality of the tea. Thanks to the locking mechanism 3, even if the internal pressure is too high during brewing, the sealing cap 2 will not be forced open, preventing hot tea from splashing and ensuring user safety.
[0042] After brewing, the user pulls the ring 57 on the top of the sealing cap 2. The ring 57 moves the mounting piece 52 upward via the pull rod 56. The mounting piece 52 causes the helical tooth block 53 to separate from the helical rack 42, releasing the restriction imposed by the helical tooth block 53 on the helical rack 42 to move closer to the locking block 31. During the movement of the mounting piece 52, the second limit rod 51 limits it to ensure smooth movement. After the helical tooth block 53 separates from the helical rack 42, the first spring 47 releases its stored elastic potential energy, causing the moving plate 43 to reset. The moving plate 43, through the helical rack 42 and the connecting plate 41, causes the sliding rod 33 to reset. The sliding rod 33 causes the locking block 31 to disengage from the fixed block 32, completing the unlocking process. At this time, the user can open the sealing cap 2 and remove the brewed tea capsule.
[0043] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
