Description

Technical Field

[0001] The utility model relates to the technical field of magnetic cup lids, in particular to a filtering structure that realizes the rapid separation of a tea strainer and a cup lid through the rotation of a ball, especially a magnetic ball type tea-water separation filtering cup lid. Background Art

[0002] A traditional filtering cup lid is a water cup lid used in the design of a tea-making cup and has a filtering function. Its structure is mainly composed of a cup lid and a built-in snap-connected tea strainer component.

[0003] For this traditional snap-connected filtering cup lid, it is usually necessary to place tea leaves inside the tea strainer component and then pour hot water from the inside of the cup mouth to brew the tea leaves. Since the tea strainer containing the tea leaves is in the upper part of the cup body, when the water volume in the cup decreases after brewing, the tea leaves will separate from the water liquid, which results in the tea leaves not being fully and effectively soaked, affecting the taste of drinking tea.

[0004] Based on this, in recent years, many units have developed some magnetic tea-water separation cup lids to achieve the purpose of fully soaking tea leaves during the tea-making process. For example, in the prior application document of the patent with the patent application number CN202321346520.9, a magnetic tea-water separation filtering cup lid is disclosed. This structure mainly uses the cooperation movement of a rotating gear and a rack to control the separation of the upper magnet and the lower magnet, and relies on its own weight to re-adsorb by inverting the cup body.

[0005] Although the above magnetic separation structure can achieve the purpose of magnetic attraction in practical applications, there are the following problems in the actual use process: First, the use of an internal rotating gear and a rack makes the manufacturing cost and manufacturing difficulty of the whole product relatively high; second, the running flexibility of the rotating gear and the rack will be reduced to a certain extent after long-term use, and the installation difficulty is relatively high.

Detailed implementation mode

[0032] The embodiments of the technical solution of the present utility model will be described in detail below in conjunction with the accompanying drawings. The following embodiments are only used to illustrate the technical solution of the present utility model more clearly, so they are only examples and cannot be used to limit the protection scope of the present utility model. The specific structure of the present utility model is as Figures 1-7 shown in the figure.

[0033] Embodiment 1: A magnetic bead magnetic adsorption type tea water separation and filtration cup lid, including a lower cup lid 1, the lower cup lid 1 is matched with the external thread on the upper part of the cup body 2 through the internal thread provided inside it. An upper cup lid 3 is provided on the upper part of the lower cup lid 1. A cavity 4 is formed between the upper cup lid 3 and the lower cup lid 1. A bead mounting tube 27 is integrally formed on the top of the lower cup lid 1 inside the cavity 4. An installation cavity 5 is formed inside the bead mounting tube 27. A magnetic bead unit 6 is movably installed inside the installation cavity 5. The bottom of the magnetic bead unit 6 abuts against the bottom of the installation cavity 5. The top of the magnetic bead unit 6 passes through the central hole at the top of the upper cup lid 3 and extends to its upper part. A tea strainer assembly is provided at the bottom of the lower cup lid 1. The top of the tea strainer assembly is magnetically adsorbed and matched with the magnetic bead unit 6 through a lower magnetic adsorption member. The lower part of the tea strainer assembly extends into the cup body 2.

[0034] It should be noted that: when the magnetic bead magnetic adsorption type tea water separation and filtration cup lid works, the whole cup lid is directly screwed onto the cup body 2. In addition, before making tea, it is necessary to disassemble the tea strainer assembly in advance and pour an appropriate amount of tea leaves into it, and then screw the tea strainer assembly to keep the tea strainer assembly magnetically fixed to the lower cup lid 1.

[0035] When it is necessary to control the fall of the tea strainer assembly, the operator can drive the entire magnetic ball unit 6 and the vertically arranged columnar upper magnet 604 inside it to rotate by rotating the top of the current magnetic ball unit 6 on the top of the upper cup lid 3. When the upper magnet 604 rotates, it will separate from the lower magnetic member. At this time, after the tea strainer assembly loses the magnetic attraction, it will fall into the hot water inside the cup body 2 under the action of gravity, enabling the tea leaves to come into full contact with the hot water, thereby achieving the purpose of fully brewing tea.

[0036] After the tea brewing is completed, invert the entire cup. At this time, under the action of its own weight, the entire tea strainer assembly will fall to the position of the lower cup lid 1, thereby enabling the tea strainer assembly to be magnetically attracted to the lower cup lid 1 again.

[0037] In any of the above solutions, preferably, the magnetic ball unit 6 includes a spherical segment ball 601. On the left and right sides of the spherical segment ball 601, support short shafts 602 are symmetrically and detachably fixedly installed. The two ends of the support short shaft 602 are respectively inserted and fitted into the rotation holes on both sides of the ball installation tube 27. A vertical through hole 603 is provided in the center of the spherical segment ball 601 from top to bottom. Upper and lower sealing members are respectively and hermetically plugged at the upper and lower parts of the vertical through hole 603. The upper sealing member and the lower sealing member are detachably fixedly connected. A vertically arranged upper magnet 604 is fitted and installed in the space between the upper sealing member and the lower sealing member. The bottom of the upper magnet 604 is magnetically attracted and matched with the top of the lower magnetic member.

[0038] It should be noted that: The entire magnetic ball unit 6 in the present invention relies on the spherical segment ball 601 as the external protective support. At the same time, through the cooperation and connection of the spherical segment ball 601 with the upper and lower sealing members, a ball surface structure is formed on the outer surface of the entire magnetic ball unit 6. The ball surface structure can ensure the smoothness of the rotation of the entire magnetic ball unit 6 and the convenience of the rotation operation.

[0039] When the magnetic ball unit 6 is assembled, since the upper magnet 604 is installed inside it, the magnetic attraction fixation can be ensured to be stable when magnetically attracting and fixing with the lower tea strainer assembly.

An internal thread blind hole 9 is provided at the center of the bottom of the upper pipe 7 of the upper spherical segment body 8, and an upper mounting post hole 10 for inserting the upper part of the upper magnet 604 is provided at the top of the internal thread blind hole 9.

[0041] Preferably, in any of the above solutions, the lower plugging member includes a lower pipe 11 arranged vertically, and a lower spherical segment body 12 is integrally formed at the top of the lower pipe 11. The center of the spherical surface at the top of the lower spherical segment body 12 is the same as the center of the spherical surface of the spherical segment ball 601 and the two spherical surfaces are matched. An external thread connecting post 13 is provided at the center of the bottom of the lower pipe 11 of the lower spherical segment body 12. The external thread connecting post 13 is matched with the internal thread on the inner side wall of the internal thread blind hole 9 through the external thread provided on its outer side wall. A lower mounting post hole 14 for inserting the lower part of the upper magnet 604 is provided at the top of the external thread connecting post 13, and the top of the lower pipe 11 abuts against the bottom of the upper pipe 7.

[0042] It should be noted that: the screwing of the upper pipe 7 in the upper plugging member and the lower pipe 11 in the lower plugging member designed in this embodiment can ensure the stability after the two are connected; in addition, through the cooperation of the enlarged upper stepped reaming 605 and the lower stepped reaming 606, the firmness of the installation parts of the upper spherical segment body 8 and the lower spherical segment body 12 and the sealing performance after relative abutment can be ensured.

[0043] Preferably, in any of the above solutions, a decorative ring 15 is further installed between the upper cup cover 3 and the lower cup cover 1. The lower part of the decorative ring 15 is sleeved on the outer side wall of the upper part of the lower cup cover 1, and the bottom of the upper cup cover 3 is clamped on the top of the decorative ring 15. The decorative ring 15 mainly plays a role in beautification.

[0044] Preferably, in any of the above solutions, the tea strainer assembly includes an upper tea strainer 16 provided at the bottom of the lower cup cover 1. A lower tea strainer 17 is screwed on the bottom of the upper tea strainer 16. A plurality of water filtering holes are provided on the outer surface of the lower tea strainer 17. The top of the upper tea strainer 16 abuts against the bottom of the lower cup cover 1. The lower magnetic part is fitted and installed in the concave cavity at the center of the top of the upper tea strainer 16, and the top of the lower magnetic part is flush with the top of the upper tea strainer 16.

[0045] The tea strainer assembly adopts a split structure in which the upper tea strainer 16 and the lower tea strainer 17 are screwed together, which can effectively ensure its convenience in use. By rotating the current lower tea strainer 17, it can be separated from the upper tea strainer 16, and then it is convenient to place tea leaves inside the lower tea strainer 17.

[0046] In any of the above solutions, preferably, the lower magnetic attraction member includes a lower magnet 18 disposed in a concave cavity at the center of the top of the upper tea strainer 16. A lower magnet cover sleeve 19 and a lower magnet iron box 20 which are cooperatively clamped are respectively disposed on the upper and lower portions of the lower magnet 18, and the lower magnet cover sleeve 19 and the lower magnet iron box 20 cooperate to cover the lower magnet 18.

[0047] The whole lower magnetic attraction member relies on the lower magnet cover sleeve 19 and the lower magnet iron box 20 to cover the internal lower magnet 18, so as to ensure that the internal lower magnet 18 does not contact with external water liquid and ensure the hygiene during use.

[0048] In any of the above solutions, preferably, an outer skin 21 is sleeved on the periphery of the lower cup cover 1.

[0050] The provided internal hexagonal screw holes 22 mainly serve the purpose of facilitating relative rotation when the upper and lower plugging members and the lower plugging member are rotationally installed, and reducing the difficulty during disassembly and installation.

[0051] Embodiment 2: Compared with Embodiment 1, the difference in this embodiment lies in that it further includes the following technical features:

[0052] A first upper sealing ring 23 is cooperatively clamped and installed at the contact surface between the bottom of the upper spherical segment 8 and the bottom of the upper stepped reaming 605, and a second upper sealing ring 26 which is hermetically fitted with the inner side wall of the upper stepped reaming 605 is cooperatively clamped on the outer side wall of the middle part of the upper spherical segment 8.

[0053] It should be noted that: The cooperation of the first upper sealing ring 23 and the second upper sealing ring 26 can double-seal the connection part between the upper spherical segment 8 and the spherical segment ball 601, improving the sealing effect.

[0054] In any of the above solutions, preferably, a first lower sealing ring 24 is cooperatively clamped and installed at the contact surface between the top of the lower spherical segment 12 and the top of the lower stepped reaming 606, and a second lower sealing ring 25 which is hermetically fitted with the inner side wall of the lower stepped reaming 606 is cooperatively clamped on the outer side wall of the middle part of the lower spherical segment 12.

[0055] It should be noted that: the cooperation between the first lower sealing ring 24 and the second lower sealing ring 25 can achieve double sealing of the connection part between the lower spherical segment body 12 and the spherical segment body ball 601, improving the sealing effect.

[0056] In addition, the double sealing provided at the upper and lower parts can also cooperate with the threaded connection in the middle to achieve the effect of preventing loosening due to vibration, ensuring the firmness during connection.

[0057] Specific working principle: Before making tea, it is necessary to disassemble the tea strainer assembly in advance and pour an appropriate amount of tea leaves into it, then screw the tea strainer assembly together to keep the tea strainer assembly magnetically fixed to the lower cup lid 1; during operation, directly screw the entire cup lid onto the cup body 2. When it is necessary to control the descent of the tea strainer assembly, the operator can drive the entire magnetic ball unit 6 and the vertically arranged columnar upper magnet 604 inside it to rotate by rotating the top of the current magnetic ball unit 6 on the top of the upper cup lid 3.

[0058] When the upper magnet 604 rotates, it will separate from the lower magnetic part. At this time, after the tea strainer assembly loses the magnetic attraction, it will fall into the hot water inside the cup body 2 under the action of gravity, enabling the tea leaves to come into full contact with the hot water, thereby achieving the purpose of making tea fully. After making tea, invert the entire cup, and under the action of its own weight, the entire tea strainer assembly will fall to the position of the lower cup lid 1, making the tea strainer assembly re-adsorb to the lower cup lid 1.

[0059] The ball magnetic attraction type tea-water separation and filtration cup lid can achieve magnetic control of the tea strainer assembly at its bottom by rotating the magnetic ball unit 6. When the tea strainer assembly separates from the magnetic ball unit 6, it can be ensured that it will fall into the cup body 2 under the action of gravity and mix fully with the hot water, enabling the tea leaves to be fully soaked and ensuring the tea-making effect; the entire tea strainer assembly adopts a quick-disassembly combined tea strainer structure, which can ensure the smoothness of tea-making, and at the same time can prevent tea leaves from scattering into the cup body 2, ensuring the tea-water separation effect.

[0060] When controlling the separation of the tea strainer, only by operating the spherical magnetic ball unit 6, it can effectively ensure the smoothness and coherence of the operation. At the same time, the entire magnetic ball unit 6 is supported by the supporting short shafts 602 on both sides, which can effectively ensure the convenience of installation of the entire structure and the convenience during subsequent use; the magnetic ball unit 6 has the magnet built-in and can ensure the isolation of the internal structure from the external water liquid by relying on multiple seals, effectively ensuring its service life.
