As a commonly used tea-making utensil, a tea kettle for boiling tea and making tea is also increasingly favored by everyone. Currently, there are various tea kettles on the market. Most tea-making kettles include a kettle body, a filter element, and a kettle lid component. A spout and a handle are provided on the kettle body, and a tea strainer for placing tea leaves is arranged in the upper part of the kettle cavity. The filter element is used for filtering tea leaves, fruit tea, flower tea, etc.

[0003] In existing tea-making utensils, the kettle body, the kettle lid, and the filter element are independent of each other. There are relatively many tea-making parts, and the processes of making tea, pouring tea, and changing tea leaves are relatively cumbersome. Especially for the clamping method between the filter element and the kettle body or the kettle lid, the existing general technology is to engage through a positioning point and a positioning slot, or two positioning points and a positioning slot, etc. During the engagement process, the operator needs to hold the filter element and rotate it half a circle or even a full circle to make the positioning point on the filter element engage with the positioning slot on the kettle body or the kettle lid. The operation is very inconvenient, and the repeated rotation causes serious wear of the mating parts. After using for a period of time, the positioning of the filter element is not good, and there is looseness and shaking in the engagement. Moreover, during the tea-making process, there will be a shaking noise under the action of steam pressure. There is no positioning structure between the existing filter element and the kettle body or the kettle lid, and there will also be rotation and shaking during use.

Another core of the present invention is to provide a tea set including the above device.

[0028] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Please refer to Figures 1 to 8 , Figure 1 Exploded schematic diagram of a specific embodiment of the tea set filter cartridge clamping device provided by the present invention; Figure 2 Cross-sectional schematic diagram of a specific embodiment of the tea set filter cartridge clamping device provided by the present invention; Figure 3 Partial enlarged view of a specific embodiment of the tea set filter cartridge clamping device provided by the present invention; Figure 4 Schematic structural diagram of a filter screen base in a specific embodiment of the tea set filter cartridge clamping device provided by the present invention; Figure 5 Top view schematic diagram of a filter screen base in a specific embodiment of the tea set filter cartridge clamping device provided by the present invention; Figure 6 Partial enlarged view of a filter screen base in a specific embodiment of the tea set filter cartridge clamping device provided by the present invention; Figure 7 Schematic structural diagram of a filter cartridge filter screen in a specific embodiment of the tea set filter cartridge clamping device provided by the present invention; Figure 8 Schematic structural diagram of a silica gel support in a specific embodiment of the tea set filter cartridge clamping device provided by the present invention.

[0030] The specific implementation of the present invention provides a tea set filter cartridge clamping device, which is installed on a tea set. The tea set includes a kettle body 3, a kettle lid 5 placed on the upper opening of the kettle body 3, and a filter cartridge filter screen 4 placed inside the kettle body 3. In order to stably place the filter cartridge filter 4, this clamping device includes an annular clamp 1 and a filter screen base 2. The clamp 1 is arranged around the upper edge of the kettle body 3. At the same time, an installation groove with an opening downward is provided on the lower end surface of the clamp 1. When the clamp 1 is installed on the upper edge of the kettle body 3, the installation groove is sleeved on the upper edge, so that the installation groove clamps the upper edge of the kettle body 3.

[0031] Furthermore, a positioning platform 11 protruding inward is provided on the inner surface of the annular clamp 1. Specifically, the positioning platform 11 is an annular platform, integrally arranged on the inner side of the clamp 1. The positioning platform 11 can be arranged at the lower side edge of the inner surface of the clamp 1, or the position of the positioning platform 11 can be adjusted according to the situation. At the same time, the annular filter screen base 2 is installed on the inner circumference of the clamp 1. The positioning platform 11 is used to support the filter screen base 2, that is, the lower end surface of the filter screen base 2 abuts against the positioning platform 11, and the positioning platform 11 prevents the filter screen base 2 from moving downward and falling off.

[0032] Among them, a supporting platform 21 protruding inward is provided on the inner surface of the filter screen base 2. Specifically, the supporting platform 21 is an annular platform, integrally arranged on the inner side of the filter screen base 2. The supporting platform can be arranged at the lower side edge of the inner surface of the filter screen base 2, or the position of the supporting platform 21 can be adjusted according to the situation. At the same time, the upper outer edge of the annular filter cartridge filter screen 4 is installed on the inner circumference of the filter screen base 2. The supporting platform 21 is used to support the upper outer edge of the filter cartridge filter screen 4.

[0033] A first limiting structure 12 is provided on the inner surface of the clamp 1, a second limiting structure 22 is provided on the outer surface of the filter screen base 2, a third limiting structure 23 is provided on the inner surface of the filter screen base 2, and a fourth limiting structure 41 is provided on the upper outer edge of the filter cartridge filter screen 4. The first limiting structure 12 and the second limiting structure 22 are matched in shape, and the two cooperate to limit the relative rotation of the clamp 1 and the filter screen base 2. The third limiting structure 23 and the fourth limiting structure 41 are matched in shape, and the two cooperate to limit the relative rotation of the filter screen base 2 and the filter cartridge filter screen 4.

[0034] During use, the clamp 1 is installed on the upper edge of the kettle body 3, and the filter screen base 2 is supported by the positioning platform 11 of the clamp 1, and the filter cartridge filter screen 4 is supported by the supporting platform 21 of the filter screen base 2. Then, the relative rotation of the clamp 1 and the filter screen base 2 is restricted by using the first limiting structure 12 and the second limiting structure 22, and the relative rotation of the filter screen base 2 and the filter cartridge filter screen 4 is restricted by using the third limiting structure 23 and the fourth limiting structure 41. That is, through the mutual cooperation of multiple components of the limiting structure, the rapid positioning of the filter cartridge filter screen 4 is realized, the situation of rotation or shaking of the filter cartridge filter screen 4 is prevented, and further component wear and noise generation are avoided, making the operation simpler and more convenient, and the disassembly, washing and replacement of tea leaves more convenient and faster.

[0035] Preferably, the third limiting structure 23 is arranged at the lower edge of the filter screen seat 2, the fifth limiting structure 24 is arranged at the upper edge of the filter screen seat 2, and the sixth limiting structure 51 is arranged on the outer contour of the pressing cover of the kettle lid 5. The fifth limiting structure 24 cooperates with the sixth limiting structure 51. Further, an annular continuous cavity 25 is arranged between the third limiting structure 23 and the fifth limiting structure 24, and a buckle protrusion 26 is arranged in the annular continuous cavity 25. The buckle protrusion 26 is buckled with the sixth limiting structure 51 to limit the relative rotation of the filter screen seat 2 and the kettle lid 5. When the kettle lid 5 is covered, due to the cooperation between the fifth limiting structure 24 and the sixth limiting structure 51, after the outer contour of the pressing cover of the kettle lid 5 smoothly passes through the area where the fifth limiting structure 24 is located, the sixth limiting structure 51 enters the annular continuous cavity 25. Specifically, it includes at least two buckle protrusions 26, which are evenly arranged along the circumference of the annular continuous cavity 25. By rotating the kettle lid 5, the sixth limiting structure 51 is clamped in the buckle protrusion 26 group, so as to play the role of being clamped in place and preventing rotation.

[0036] The polygonal tooth structure of the kettle lid 5 includes sixteen teeth, and the tooth top is rounded. The distance between the convex point of the buckle protrusion 26 group and the rotation center is less than the distance between the highest point of the tooth top of the plastic pressing cover of the kettle lid 5 that is matched, and the matching amount of the cross collision between the two is 0.65 mm. The method to prevent over-clamping is: the tooth top of the plastic pressing cover of the kettle lid 5 is rounded, and the diameter of the convex point is controlled below 2 mm. The method to prevent excessive rotation is: the height difference between the baffle and the convex point is 1.09 mm, to prevent the cooperating flower-shaped gear from rotating too much. The plastic pressing cover is evolved from a regular hexadecagon, has sixteen corners, and can be rotated in cooperation with any corner, which can realize the functions of high-efficiency picking and placing and blind covering. Only the two corners corresponding to the straight line in the hexadecagon cooperate with another part. According to permutation and combination, there are eight combination methods in total, which improves the service life. The buckle protrusion 26 group can be set to two or more. The advantage of multi-point cooperation is that the wear is uniformized, the positioning is better, and the service life is longer. The sizes and structures of each component can also be adjusted according to the situation, which are all within the protection scope of the present invention.

[0037] In the tea set filter cartridge clamping device provided by the specific embodiment of the present invention, the first limiting structure 12 and the second limiting structure 22 are specifically polyhedron structures with concave-convex cooperation. This structure makes the surface of the components smoother, prevents scraping and wear. At the same time, since both of them are annular structures, under the condition of ensuring dimensional cooperation, that is, the outer peripheral dimension of the filter screen seat 2 is slightly smaller than the inner peripheral dimension of the clamp 1, the outer periphery of the filter screen seat 2 is in full contact with the inner periphery of the clamp 1, and a polyhedron structure that is not too protruding can be used to achieve rotational limitation. Specifically, the second limiting structure 22 is a plurality of small planes that are continuously processed and arranged in sequence along the circumferential direction on the arc-shaped outer surface of the filter screen seat 2. The raised edge structure is formed between adjacent small planes. At the same time, the cross section of the first limiting structure 12 can be a polygonal structure with the same shape, and the two are perfectly matched.

[0038] The third limiting structure 23 and the fifth limiting structure 24 are specifically polygonal retaining edges, forming an annular continuous cavity 25, wherein the polygonal baffle is a plurality of arc convex structures arranged continuously along the circumference, that is, the vacant part in the middle of the cross section of the third limiting structure 23 and the fifth limiting structure 24 is a polygonal toothed structure, and the fourth limiting structure 41 and the sixth limiting structure 51 are specifically polygonal toothed structures, with arc-shaped grooves between the teeth, so as to achieve the concave-convex fit between the polygonal retaining edges and the polygonal toothed structures, limit the rotation but not the circumferential movement, so that the tea set can be smoothly disassembled and assembled. Or the shape of each limiting structure can be adjusted according to the situation, such as a radial toothed structure or a keyway structure, which is within the protection scope of the present invention.

[0039] Furthermore, a locking structure 13 is provided on the outer periphery of the clamp 1 for locking the clamp 1 and stably fixing it on the kettle body 3, so that the inner and outer sides of the upper edge of the kettle body 3 are wrapped by the clamp 1, and a glue groove 14 is provided on the inner side where the clamp 1 cooperates with the kettle body 2. The glue groove 14 is used to position the clamp 1 and plays a role in sealing, heat insulation and vibration reduction.

[0040] In the tea filter liner clamping device provided in the above-mentioned specific embodiments, the support platform 21 is covered with a silicone holder 6, so that the silicone holder 6 wraps the end of the support platform 21 extending inward, and the silicone holder 6 contacts the outer edge of the upper end of the filter liner 4. The outer edge of the upper end of the filter liner 4 will not directly contact the support platform 21, but will be isolated and supported by the silicone holder 6, so as to reduce vibration, prevent slipping and reduce wear. Specifically, the silicone holder 6 is arranged in an annular manner. In order to continuously wrap the support platform 21, the vertical cross-section of the silicone holder 6 is two C-shaped structures with openings facing away from each other, and the C-shaped structure wraps the end of the support platform 21. And the bottom edge of the silicone holder 6 is an arc edge, which is the same shape as the end of the positioning platform 11 and abuts against it, and the top edge of the silicone holder 6 is a toothed edge, which is the same shape as the third limiting structure 23 and abuts against it. That is, the silicone holder 6 is an annular ring, and an annular rib is set at both the upper and lower ends of the annular ring. The annular rib extends outward to form an annular groove with an opening facing outward, and the annular groove wraps the support platform 21, and the outer edge of the bottom edge is circular, and the outer edge of the top edge is toothed.

[0041] Among them, the cross-sectional surface of the filter seat 2 is a vertical "concave" shape, and the protruding part at the bottom is the support platform 21. The outer end of the support platform 21 is against the positioning platform 11, and the inner free end of the support platform 21 is sleeved with a silicone holder 6. The cross-sectional surface of the silicone holder 6 is two "匚" shapes with openings facing away from each other, and the outer edge of the upper end of the filter 4 is placed on the upper end surface of the silicone holder 6.

[0042] During use, place the clamp 1 on the upper edge of the kettle body 3, lock the clamp 1 through the locking structure 13, put the silicone tray 6 on the support platform 21 of the filter screen base 2, place the filter screen base with the silicone tray 6 into the clamp 1, and support and fix the position of the filter screen base 2 by the positioning platform 11. Then, put the filter element filter screen 4 into the kettle body 3. The upper outer edge of the filter element filter screen 4 is supported by the silicone tray 6 to fix the position of the filter element filter screen 4. When the kettle lid 5 is covered, the sixth limiting structure 51 of the kettle lid 5 enters the annular continuous cavity 25, and the rotation of each component is restricted by each limiting structure.

Specific examples are used herein to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention.
