Description

Technical Field

[0001] This utility model relates to the field of teaware technology, specifically to a tea brewing structure. Background Technology

[0002] Currently, teapots, also known as tea infusers, are popular among many users due to their tea brewing and filtering functions. Existing teapots offer different solutions for water level control during brewing, generally divided into contact-type push-to-drain and non-contact magnetic control water dispensing. In teapots with magnetic control water dispensing, the magnetic control components are usually distributed inside the handle or lid, such as in publication number CN217987241U, a sliding control filter structure and a tea infuser containing the filter structure, and publication number CN117017036A, a magnetic water dispensing structure and a smart teapot.

[0003] While these structures are simple and easy to operate, their simplicity also makes the teapot's function very limited. Furthermore, they lack operability and playability in terms of control, which can easily lead to aesthetic fatigue. Therefore, it is necessary to develop a teapot that is more playable and has more functions. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a tea-brewing structure with more complete functions and increased playability.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A tea brewing structure includes a teapot body and a base, the teapot body being detachably placed on the base, the teapot body including an outer cup and an inner cup for brewing tea placed above the outer cup;

[0007] The bottom of the inner cup is provided with a through hole, and a drain assembly is provided on the through hole;

[0008] The drainage assembly includes a drain nozzle with a water outlet at the bottom, a filter screen above the drain nozzle, the drain nozzle and the filter screen forming a receiving cavity, and a first magnetic control assembly for sealing the water outlet is provided in the receiving cavity.

[0009] The base contains a second magnetic control component and a motor. The motor engages with the second magnetic control component, driving the second magnetic control component to change its position and magnetic field direction simultaneously, so that the first magnetic control component can switch between two states: blocking the water outlet and opening the water outlet.

[0010] In a preferred embodiment, the second magnetic control assembly includes a slider, the motor engages with the slider to drive the slider to move horizontally, and an active strong magnet is rotatably connected to the slider. When the motor drives the slider to move horizontally, the active strong magnet rolls between a generally horizontal first position and a second position within the base.

[0011] In a preferred embodiment, the slider is provided with a first rack, the output shaft of the motor is provided with a first gear, the first rack meshes with the first gear, and the slider is provided with a rotating shaft, the active strong magnet being rotatably connected to the slider through the rotating shaft.

[0012] In a preferred embodiment, the first magnetic control component has a blocking position located at the water outlet and an open water position located off the water outlet and against the side wall of the accommodating cavity, wherein the blocking position and the open water position are determined according to the position and orientation of the second magnetic control component.

[0013] In a preferred embodiment, when the motor drives the active strong magnet to roll between a generally horizontal first position and a second position within the base, the first position is generally located vertically below the water outlet, and the second position is offset from vertically below the water outlet. The magnetic pole direction of the active strong magnet switches between a first direction in which the S / N poles face the first magnetic control component and a second direction formed by rotating 45-315°.

[0014] In a preferred embodiment, the base is provided with a second rack, and the active strong magnetic synchronous rotation is connected to a second gear, with the second rack meshing with the second gear.

[0015] In a preferred embodiment, the water outlet has an inwardly folded edge, which together with the sidewall of the accommodating cavity forms two support points that support the first magnetic control assembly when the water outlet is opened.

[0016] In a preferred embodiment, the first magnetic control component includes an arc-shaped sealing head and a passive strong magnet, the passive strong magnet being encapsulated in a food-grade material.

[0017] In a preferred embodiment, the head of the first magnetic control component has an arc-shaped sealing head, and extends from the head of the sealing head to the back to form a chamber that encloses the passive strong magnet, which is a radial strong magnet that is generally columnar.

[0018] In a preferred embodiment, a heating module is provided inside the base near the upper surface.

[0019] Compared with the prior art, the present invention has the following advantages.

[0020] By adding the base and incorporating magnetic control within it, the weight of the handle or lid of the teapot is reduced, minimizing the arm strain required for tea brewing and making it more user-friendly. Furthermore, the overall center of gravity of the teapot is more even, resulting in greater stability and preventing it from tipping over.

[0021] In addition, the base is used for opening and closing the water supply, which not only conforms to the operating habits of most people who operate kettles, but also allows for more options in the design of the operating points based on the circuit, solving the limitation that the traditional operating buttons must be located on the handle or the lid. This greatly increases the design and playability of the product.

[0022] Furthermore, by adding a heating module to the base to keep the tea warm, combined with the tea-brewing water-draining function, the brewed tea can be kept at a set ideal temperature without being moved, providing a better tea flavor. Attached Figure Description

[0035] Example 1

[0036] Reference Figures 1-6This embodiment provides a tea brewing structure, including a teapot body 1 and a base 2. The teapot body 1 can be detachably placed on the base 2. The teapot body 1 includes an outer cup 11 and an inner cup 12 for brewing tea, which is placed inside and above the outer cup 11. The bottom of the inner cup 12 is provided with a through hole, and a water drain assembly 3 is provided on the through hole. The water drain assembly 3 includes a water spout 31 with a water outlet at the bottom, and a filter screen 32 is provided above the water spout 31. The water spout 31 and the filter screen 32 form a receiving cavity, and a first magnetic control assembly 4 for sealing the water outlet is provided in the receiving cavity.

[0037] The base 2 is equipped with a second magnetic control component 5 and a motor 6. The motor 6 engages with the second magnetic control component 5, driving the position and magnetic field direction of the second magnetic control component 5 to change simultaneously, so that the first magnetic control component 4 can switch between two states: blocking the water outlet and opening the water outlet.

[0038] In other words, the first magnetic control component 4 is remotely controlled by the second magnetic control component 5, so that the first magnetic control component 4 can block the water outlet when brewing tea, and open the water outlet to let water out after brewing. The control method is to change the position, distance and magnetic field direction of the second magnetic control component 5 through meshing transmission, so as to change the magnetic force. The corresponding technical principles and references have been mentioned in the background art.

[0039] In a preferred embodiment, the second magnetic control component 5 includes a slider 51, and the motor 6 engages with the slider 51 to drive the slider 51 to move horizontally. An active strong magnet 52 is rotatably connected to the slider 51. When the motor 6 drives the slider 51 to move horizontally, the active strong magnet 52 rolls between a roughly horizontal first position and a second position within the base 2. Using the motor 6 as the power output, based on the circuit connection, more selectivity in the operation point can be achieved. For example, the control point can be close to the bottom of the kettle body 1, or far from the bottom of the kettle body 1, or even wirelessly controlled from other terminals, such as mobile phones. It should be noted that the vertical freedom of the slider 51 can be restricted by means of a pressure plate, guide rail, or the distance between the upper and lower walls of the base 2 to ensure that the slider 51 remains horizontal when moving.

[0040] In a preferred embodiment, the slider 51 is provided with a first rack 511, the output shaft of the motor 6 is provided with a first gear, the first rack 511 meshes with the first gear, and the slider 51 is provided with a rotating shaft 512, the active strong magnet 52 is rotatably connected to the slider 51 through the rotating shaft 512.

[0041] In other words, the motor 6 outputs power in both forward and reverse rotation, driving the first gear to rotate, and through the first rack 511 meshing with it, it drives the slider 51 to move horizontally, ultimately pulling the active strong magnet 52 to roll between the approximately horizontal first position and the second position within the base 2.

[0042] In a preferred embodiment, the first magnetic control component 4 has a blocking position located at the water outlet and an open water position located off the water outlet and against the side wall of the accommodating cavity. Water is discharged when the open water position is reached. The blocking position and the open water position are determined according to the position and orientation of the second magnetic control component 5.

[0043] In a preferred embodiment, the motor 6 drives the active magnet 52 to move between a generally horizontal first position and a second position within the base 2. The first position is approximately vertically below the water outlet, and the second position is offset from vertically below the water outlet. The magnetic pole direction of the active magnet 52 switches between a first direction in which the S / N poles face the first magnetic control component 4, and a second direction formed by rotating 45-315°. The motor 6 can convert the rotational power of its output shaft into linear power through a lead screw structure, thereby driving the active magnet 52 to roll.

[0044] In this embodiment, the first position is further described in particular, which is located approximately vertically below the outlet. At this position, the second magnetic control component 5 is closest to the first magnetic control component 4 and the magnetic poles are oriented toward the first magnetic control component 4, resulting in the greatest mutual magnetic force. As the distance increases from the first position to other positions that are approximately horizontal, the mutual magnetic force decreases.

[0045] In this specific embodiment, at least the following status bits are guaranteed:

[0046] When the drain is turned on, the second magnetic control component 5 is in the first position, and at this time the magnetic poles of the second magnetic control component 5 and the first magnetic control component 4 are in a state of relative and repulsion, which causes the first magnetic control component 4 to deviate from the water outlet, forming a drain channel.

[0047] When the drain is closed, the repulsive force between the second magnetic control component 5 and the first magnetic control component 4 decreases after the second magnetic control component 5 rolls. The repulsive force is not enough to push the first magnetic control component 4 away. Even after rotating 180°, the repulsion turns into attraction. At this time, the first magnetic control component 4 is attracted and blocks the water outlet, thus closing the drain channel.

[0048] In a preferred embodiment, the base 2 is provided with a second rack 21, and the active strong magnet 52 is synchronously rotatably connected to a second gear 521, with the second rack 21 meshing with the second gear 521. The second rack 21 is fixedly connected to the base 2, and one end of the second gear 521 is fixedly connected to the active strong magnet 52, with both coaxial. This design provides better accuracy assurance for the rolling distance and angle of the second magnetic control component 5.

[0049] In a preferred embodiment, the water outlet has an inwardly folded edge, which, together with the sidewall of the accommodating cavity, forms two support points for the first magnetic control assembly 4 when the water outlet is opened. This design actually provides better stability when maintaining the water flow state.

[0050] In a preferred embodiment, the first magnetic control component 4 includes an arc-shaped sealing head 41 and a passive strong magnet 42, the passive strong magnet 42 being encased in food-grade material.

[0051] In a preferred embodiment, the first magnetic control component 4 has an arc-shaped sealing head 41. Extending from the head of the sealing head 41 towards the back, it forms a chamber that encloses the passive strong magnet 42, which is a roughly cylindrical radial strong magnet. This bullet-shaped design also helps maintain stability. The arc-shaped head is positioned near the water outlet, while the passive strong magnet 42 is positioned away from the water outlet, maintaining a relatively stable magnetic field direction for the internal radial strong magnet, thus cooperating with the active strong magnet 52.

[0052] In a preferred embodiment, a heating module 7 is provided inside the base 2 near the upper surface. The heating module 7 is mainly used to keep the tea soup warm or heat it.

[0053] Example 2

[0054] Reference Figure 7 The difference between this embodiment and Embodiment 1 lies in the structure used to place the inner cup 12 above the outer cup 11, as detailed below:

[0055] The inner cup 12 includes an upper cup body and a lower cup body that are connected to each other. The outer diameter of the upper cup body is larger than the outer diameter of the lower cup body. The base 2 is provided with a bracket 8. The upper end of the bracket 8 is connected to a roughly horizontal support ring 9. The inner diameter of the support ring 9 is larger than the outer diameter of the lower cup body and smaller than the outer diameter of the upper cup body, so that it can fit over and support the inner cup 12, so that the inner cup 12 is placed above the outer cup.

[0056] In this specific embodiment, when the inner cup 12 is secured by the support ring 9, the inner cup 12 is located directly above the outer cup 11, and the bottom height of the drain assembly 3 is greater than the rim height of the outer cup 11. This design effectively prevents the outer cup 11 from colliding with the inner cup 12 or the drain assembly 3 when the outer cup 11 is placed on or removed from the base 2.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
