Description

Technical Field

[0001] This utility model relates to the field of teaware technology, specifically to a magnetically controlled teapot. 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 results in a very limited function for the teapot. Furthermore, the lack of operability and playability in control can easily lead to aesthetic fatigue. Additionally, the shape of the teapot is a crucial factor influencing customer purchasing decisions. The aforementioned structures integrate the magnetic control components, requiring careful consideration of the component's placement during the design phase, thus imposing constraints on the teapot's appearance. Therefore, there is a need to develop a teapot that offers greater playability and design flexibility, as well as more functions. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model proposes a magnetically controlled teapot with more complete functions, increased playability and designability.

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

[0006] A magnetically controlled teapot includes a teapot body and a base, wherein the teapot body can be detachably placed on the base, and the teapot body includes 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 is provided with a second magnetic control component and a third magnetic control component. The second magnetic control component is attracted to the first magnetic control component, and the third magnetic control component is repelled by the first magnetic control component. By changing the position of the second magnetic control component, the first magnetic control component can switch between blocking the water outlet and opening the water outlet.

[0010] In a preferred embodiment, the second magnetic control component includes an active strong magnet, and a driving mechanism is provided in the base to drive the active strong magnet to deflect around a rotating axis between a generally horizontal first position and a second position in the base.

[0011] In a preferred embodiment, the drive mechanism includes a motor, a swing element, and a gear and rack structure. One end of the swing element is fixedly connected to the active strong magnet, and the other end of the swing element is rotatably connected to the rotating shaft. The motor is connected to the swing element through the gear and rack structure.

[0012] In a preferred embodiment, the gear rack structure includes a transmission rack that moves horizontally and linearly within the base. Both ends of the transmission rack are respectively engaged with a driving gear and a driven gear. The driving gear is fixedly connected to the output shaft of the motor, and the driven gear is rotatably connected to the rotating shaft and fixedly connected to the swing member.

[0013] In a preferred embodiment, a guide groove and a limiting beam are fixedly provided inside the base, and the transmission rack slides along the guide groove between the bottom surface of the inner wall of the base and the limiting beam.

[0014] In a preferred embodiment, the third magnetic control component includes an auxiliary strong magnet, which is fixedly disposed within the base on a side offset from the vertically below the first magnetic control component, and the magnetic force of the auxiliary strong magnet on the first magnetic control component is less than the magnetic force of the active strong magnet on the first magnetic control component.

[0015] In a preferred embodiment, the first magnetic control component has a blocking position located at the water outlet and an open water level when it is offset from the water outlet and leans against the side wall of the accommodating cavity, the blocking position and the open water level being determined according to the position of the second magnetic control component.

[0016] In a preferred embodiment, when the driving mechanism drives the active strong magnet to move 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, with the S / N poles of the active strong magnet facing the first magnetic control component.

[0017] In a preferred embodiment, the water outlet has an inwardly folded edge, which together with the sidewall of the accommodating cavity forms a support point for the first magnetic control component when the water outlet is opened.

[0018] In a preferred embodiment, the first magnetic control assembly includes an arc-shaped sealing head and a passive strong magnet. A chamber is formed extending from the head to the back of the first magnetic control assembly, which encloses the passive strong magnet. The passive strong magnet is a radial strong magnet that is generally cylindrical and is encased in food-grade material.

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

[0020] By adding the base and incorporating the magnetic control mechanism within it, the limitation that existing magnetic control mechanisms must be placed on the kettle body is resolved. This allows designers to fully unleash their creativity, greatly increasing the design possibilities of the product.

[0021] Furthermore, by incorporating magnetic control into the base, 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. In addition, the overall center of gravity of the teapot is more even, making it more stable and less prone to tipping over.

[0022] 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. Attached Figure Description

[0035] Reference Figures 1-7

[0036] A magnetically controlled teapot includes 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 above the outer cup 11.

[0037] The bottom of the inner cup 12 is provided with a through hole, and a drain assembly 3 is provided on the through hole;

[0038] The drainage assembly 3 includes a drain nozzle 31 with a water outlet at the bottom, a filter screen 32 above the drain nozzle 31, the drain nozzle 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.

[0039] The base 2 is provided with a second magnetic control component 5 and a third magnetic control component 10. The second magnetic control component 5 is attracted to the first magnetic control component 4, and the third magnetic control component 10 is repelled by the first magnetic control component 4. By changing the position of the second magnetic control component 5, the first magnetic control component 4 can switch between two states: blocking the water outlet and opening the water outlet.

[0040] In other words, the first magnetic control component 4 is remotely controlled by the cooperation of the second magnetic control component 5 and the third magnetic control component 10, 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 of the second magnetic control component 5, so that the magnetic force acting on the first magnetic control component 4 changes. The corresponding technical principles and references have been mentioned in the background art.

[0041] In a preferred embodiment, the second magnetic control component 5 includes an active strong magnet 51, and a driving mechanism is provided in the base 2 to drive the active strong magnet 51 to deflect around a rotating shaft 52 between a generally horizontal first position and a second position in the base 2, thereby changing the distance between the active strong magnet 51 and the first magnetic control component 4, and thus changing the magnetic attraction force of the active strong magnet 51 on the first magnetic control component 4.

[0042] In a preferred embodiment, the drive mechanism includes a motor 53, a swing member 54, and a gear and rack structure. One end of the swing member 54 is fixedly connected to the active strong magnet 51, and the other end of the swing member 54 is rotatably connected to the rotating shaft 52. The motor 53 is connected to the swing member 54 through the gear and rack structure.

[0043] Specifically, the active strong magnet 51 is fixedly sleeved on one end of the swing member 54, and the motor 53 drives the other end of the swing member 54 to rotate around the rotating shaft 52 through a gear and rack structure, which in turn drives the active strong magnet 51 to swing horizontally around the rotating shaft 52. The distance between the active strong magnet 51 and the first magnetic control component 4 changes accordingly. In addition, by using the motor 53 as the power output, based on the circuit connection, more selectivity of the operation point can be achieved. For example, the control point can be close to the bottom of the kettle body 1 or far away from the bottom of the kettle body 1, or even wirelessly controlled on other terminals, such as mobile phones.

[0044] In a preferred embodiment, the gear rack structure includes a transmission rack 55, which moves horizontally and linearly within the base 2. Both ends of the transmission rack 55 are respectively engaged with a driving gear 56 and a driven gear 57. The driving gear 56 is fixedly sleeved with the output shaft of the motor 6, and the driven gear 57 is rotatably connected to the rotating shaft 52 on the same axis and is fixedly connected to the swing member 54.

[0045] Specifically, when the motor 53 is running, the drive gear 56 rotates axially, driving the transmission rack 55 meshing with it to move horizontally in a straight line, which causes the driven gear 57 to rotate around the rotating shaft 52 as the central axis, and then drives the drive magnet 51 to swing around the rotating shaft 52 as the central axis through the swinging member 54.

[0046] As an optional embodiment, the axis of the driving gear 56 is parallel to the horizontal plane; the axis of the rotating shaft 52 is perpendicular to the horizontal plane; the transmission rack 55 includes two tooth segments integrally formed, wherein the tooth protrusion of one tooth segment faces upward and meshes with the driving gear 56, and the tooth protrusion of the other tooth segment faces the driven gear 57 and meshes with it.

[0047] In a preferred embodiment, a guide groove 6 and a limiting beam 7 are fixedly provided inside the base 2, and the transmission rack 55 slides along the guide groove 6 between the bottom surface of the inner wall of the base 2 and the limiting beam 7.

[0048] Specifically, one end of the limiting beam 7 is connected to the top of the rotating shaft 52, and the other end of the limiting beam 7 is fixedly connected to the base 2 through the column, forming an arch bridge structure that spans the transmission rack 55. While not affecting the horizontal linear movement of the transmission rack 55, it restricts the degree of freedom of the transmission rack 55 in the vertical direction, effectively preventing the transmission rack 55 from disengaging from the guide groove 6 in the vertical direction.

[0049] Understandably, the direction of movement of the transmission rack 55 can also be guided by a guide rail.

[0050] As an optional embodiment, two baffles are fixedly installed inside the base 2. When the active strong magnet 51 moves to the first position and the second position, it abuts against the two baffles respectively, which is used to limit the swing angle of the active strong magnet 51.

[0051] In a preferred embodiment, the third magnetic control component 10 includes an auxiliary strong magnet, which is fixedly disposed in the base 2 on a side offset from the vertically below the first magnetic control component 4, and the magnetic force of the auxiliary strong magnet on the first magnetic control component 4 is less than the magnetic force of the active strong magnet 51 on the first magnetic control component 4.

[0052] In this specific embodiment, at least the following status bits are guaranteed:

[0053] With the drain closed, the active strong magnet 51 is in the first position. At this time, the active strong magnet 51 and the magnetic pole of the first magnetic control component 4 are in a state of being opposite and attracting each other, while the auxiliary strong magnet and the magnetic pole of the first magnetic control component 4 are in a state of being deviated and repelling each other. Since the magnetic force of the auxiliary strong magnet on the first magnetic control component 4 is less than the magnetic force of the active strong magnet 51 on the first magnetic control component 4, the first magnetic control component 4 can block the water outlet and close the drain channel under the attraction of the active strong magnet 51.

[0054] When the drain is turned on, the active strong magnet 51 is in the second position. At this time, the active strong magnet 51 and the magnetic pole of the first magnetic control component 4 are in a state of being offset from each other and attracting each other, while the auxiliary strong magnet and the magnetic pole of the first magnetic control component 4 are in a state of being offset from each other and repelling each other. The attraction of the active strong magnet 51 and the repulsion of the auxiliary strong magnet act on the first magnetic control component 4 at the same time and in the same direction, so that the first magnetic control component 4 will deviate from the water outlet to form a drain channel.

[0055] 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, wherein the blocking position and the open water position are determined according to the position of the second magnetic control component 5.

[0056] In a preferred embodiment, when the driving mechanism drives the active strong magnet 51 to move between a generally horizontal first position and a second position within the base 2, the first position is generally located vertically below the water outlet, the second position is offset from vertically below the water outlet, and the S / N poles of the active strong magnet face the first magnetic control component 4.

[0057] In particular, it is further explained that when the active strong magnet 51 is in the first position, the second magnetic control component 5 is closest to the first magnetic control component 4 and the magnetic pole direction is towards the first magnetic control component 4, the mutual magnetic force is the greatest, the first magnetic control component 4 has a good sealing effect on the water outlet, and can greatly reduce the influence of the auxiliary strong magnet on the first magnetic control component 4. Furthermore, when moving from the first position to other positions that are roughly horizontal, the distance between the second magnetic control component 5 and the first magnetic control component 4 increases, the mutual magnetic force decreases, and the repulsive force of the auxiliary strong magnet on the first magnetic control component 4 increases.

[0058] 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.

[0059] In a preferred embodiment, the first magnetic control component 4 includes an arc-shaped sealing head 41 and a passive strong magnet 42. A chamber is formed extending from the head to the back of the first magnetic control component 4, enclosing the passive strong magnet 42. The passive strong magnet 42 is a generally columnar radial strong magnet, encased in food-grade material. This bullet-like design also helps maintain stability. The sealing head 41 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 51.

[0060] In a preferred embodiment, 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. Furthermore, a support 8 is provided on the base 2. The upper end of the support 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, thereby enabling it to fit over and support the inner cup 12, placing the inner cup 12 above the outer cup.

[0061] In this 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.

[0062] As an optional embodiment, a heating module is provided inside the base 2 near the upper surface. The heating module is mainly used to keep the tea soup warm or heat it. Combined with the water dispensing function of the tea brewing machine, it can maintain the brewed tea at a set ideal temperature without moving it, providing a better tea flavor.

[0063] 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.
