Description

Technical Field

[0001] This utility model relates to the field of teaware, and in particular to a teapot based on a magnetic switch. Background Technology

[0002] A teapot can fully steep tea leaves and then filter out the tea leaves to obtain tea that meets the user's needs.

[0003] Existing teapots typically use a method of separating the tea leaves from the water by lifting the tea strainer directly from the teapot. However, this method requires a relatively deep water level in the teapot to soak the tea leaves in the tea strainer. Moreover, during the soaking process, most of the water cannot fully contact the tea leaves. In addition, users need to frequently lift the tea strainer from the teapot or place it on the teapot, which increases the difficulty of operation.

[0004] A search revealed that application number CN202422090537.3 discloses a sliding magnetic control teapot, comprising a teapot body, a tea compartment, and a magnetic control assembly. The tea compartment is detachably disposed in the spout of the teapot body, and a water outlet is located at the center of the bottom of the tea compartment, with a movable magnetic switch in the water outlet. The magnetic control assembly is disposed on the outer wall of the teapot body and includes a control shell, a first magnet, and a sliding operating component. The control shell is disposed on the outer wall of the teapot body, the first magnet is disposed inside the control shell, and the sliding operating component is disposed on the control shell and connected to the first magnet, and can push the first magnet to slide between an open position and a closed position. When the first magnet switches from the closed position to the open position, the magnetic force between the first magnet and the magnetic switch forces the magnetic switch to open the water outlet. However, in this technical solution, the magnetic switch is a movable magnetic block structure set at the bottom of the internal tea compartment. During operation, the first magnet slides up and down on the handle side. Because the first and second magnets are far apart, and the magnetic switch is affected by changes in magnetic force, the controllability of the flipping activity is poor. It is easy to cause insufficient or excessive flipping, which in turn affects the opening and closing effect. Utility Model Content

[0005] This invention provides a teapot based on a magnetic switch, which helps to solve the problem of unstable magnetic control effect in some current teapots.

[0006] This utility model is implemented as follows:

[0007] A teapot based on a magnetic switch includes a teapot body with a handle on one side. An inner liner is detachably installed at the top opening of the teapot body, and a lid is detachably installed at the top opening of the inner liner. A water outlet is provided at the bottom of the inner liner, connecting the inner cavity of the inner liner to the inner cavity of the teapot body. A filter screen is provided above the water outlet, and a valve stem that can move up and down is movably connected to the filter screen. A ball is provided at the bottom of the valve stem, which can block the water outlet to form a closed structure. A follower magnetic block is fixed at the top of the valve body, and an opening and closing magnetic block that can move laterally is provided on the lid. When the opening and closing magnetic block moves to directly above the follower magnetic block, it can magnetically attract the follower magnetic block, so that the valve stem moves up and the ball disengages from the water outlet, thus forming an open control structure for the water outlet.

[0008] Based on the above technical solution, the cover includes a panel, a sliding groove at the top of the panel, a perforation with a strip-shaped longitudinal through hole structure at the bottom of the sliding groove, an upper slider is movably connected in the sliding groove, a connecting rod is provided at the bottom of the upper slider, the connecting rod extends through the perforation to the bottom of the panel and connects to a lower slider, the lower slider and the upper slider form a synchronous linkage structure, the opening and closing magnetic block is set on one side of the bottom of the lower slider, and a bottom shell is connected to the bottom of the panel, the bottom shell and the panel enclose the lower slider inside.

[0009] Based on the above technical solution, a locking magnetic block is provided between the lower slider and the panel. The locking magnetic block includes a first magnetic block fixed to the bottom of the panel and a second magnetic block fixed to the lower slider. The second magnetic block is located at the end of the lower slider that is far away from the locking magnetic block. After the lower slider moves laterally to the threshold position with the upper slider, the second magnetic block is located directly below the first magnetic block to form a magnetic attraction limiting structure.

[0010] Based on the above technical solution, the sliding groove and the bottom surface of the panel are provided with protruding ridges, which are located on the sliding paths of the upper slider and the lower slider.

[0011] Based on the above technical solution, the bottom of the inner liner is provided with a valve seat, the water outlet is located at the center of the valve seat, the top of the water outlet has a spherical groove that adapts to the outer contour of the bottom of the ball, the valve seat is provided with a cylinder directly above the water outlet, the inner cavity of the cylinder above the water outlet is connected to the inner cavity of the inner liner, and the bottom of the valve stem and the ball are located inside the cylinder.

[0012] Based on the above technical solution, the filter screen is set horizontally, and a vertical guide tube is set at the top center position. The valve stem passes vertically through the inside of the guide tube, and the guide tube constitutes the guiding and limiting structure of the valve stem.

[0013] Based on the above technical solution, the second magnetic block is located at one end of the top of the lower slider.

[0014] Based on the above technical solution, the protruding ridge is at least two parallel linear flange structures, and the length direction of the protruding ridge is parallel to the sliding direction of the upper slider and the lower slider.

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] 1. This utility model, by placing the opening and closing magnetic block on the cover and using lateral displacement to interact with the follower magnetic block, significantly shortens the effective distance of magnetic action compared to the existing technology where the first magnet and the magnetic switch are far apart and slide up and down. This reduces the attenuation and variation of magnetic force during transmission. This close-range magnetic control design makes the flipping activity of the magnetic switch (valve stem and ball) more controllable. The valve stem moves straight up and down to switch the opening and closing state of the water outlet. This method is more stable and effectively avoids the problems of insufficient or excessive flipping, thereby significantly improving the stability of the magnetic control effect and ensuring the accuracy and reliability of the water outlet opening and closing.

[0017] 2. In use, the teapot of this invention allows users to easily control the flow of tea by simply pushing the upper slider horizontally, thus enabling the magnetic attraction or separation of the opening and closing magnetic blocks and the follower magnetic block. This operation method is more ergonomic, intuitive, and convenient, eliminating the need for frequent lifting and placing of the tea strainer as with traditional teapots. It significantly reduces the difficulty of operation and is especially suitable for users who need to adjust the water flow multiple times during tea brewing, improving efficiency and the overall tea-brewing experience.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0029] Combination Figures 1 to 8 This embodiment discloses a teapot based on a magnetic control switch, an innovative tea utensil design. By cleverly utilizing the magnetic control principle and combining it with a unique mechanical structure design, it achieves precise control over the water flow from the teapot. The teapot mainly consists of a body 100, an inner liner 300, a lid 400, and related magnetic control components. These components work together to complete the functions of brewing tea and controlling water flow.

[0030] In this embodiment, the teapot specifically includes a body 100, which is made of glass. The body 100 serves as the main container of the entire teapot and is used to hold water. Figure 1 and Figure 2 As shown, a handle 200 is provided on one side of the kettle body 100. The handle 200 has a D-shaped structure and is connected and fixed to the side wall of the kettle body 100 by means of adhesive or screws. The function of the handle 200 is to facilitate the user's grip and operation.

[0031] Combination Figure 3The teapot body 100 has a detachable inner liner 300 at its top opening. The top periphery of the inner liner 300 has a flange, which allows it to be inserted into the opening of the teapot body 100 to form a snap-fit ​​structure. The inner liner 300 is used to hold tea leaves, and its detachable design facilitates cleaning and tea leaf replacement. In this embodiment, the inner liner 300 is also made of glass.

[0032] The inner liner 300 has a detachable cover 400 at the top opening. The cover 400 serves to seal and protect the tea leaves in the inner liner 300, while also providing an installation location for the magnetic control components.

[0033] Furthermore, the bottom of the inner liner 300 is provided with a valve seat 310, and the center of the valve seat 310 is provided with a water outlet 311 that connects the inner cavity of the inner liner 300 and the inner cavity of the pot body 100. The water outlet 311 is the channel through which tea flows from the inner liner 300 to the pot body 100.

[0034] A filter screen 500 is installed above the water outlet 311. The filter screen 500 is a horizontal stainless steel filter screen 500 with evenly distributed filter holes. The function of the filter screen 500 is to filter tea leaves and prevent tea leaves from flowing out with the tea water.

[0035] A guide tube 510 is located at the top center of the filter screen 500. A valve stem 600, capable of vertical movement, is movably connected inside the guide tube 510. The valve stem 600 includes a vertical shaft 610 and a ball 620 at its bottom. The ball 620 can block the water outlet 311, forming a closed structure to prevent tea from flowing out. Specifically, the valve stem 600 passes vertically through the guide tube 510. The guide tube 510 constitutes a guiding and limiting structure for the valve stem 600, ensuring that the valve stem 600 remains vertical during its vertical movement and does not deviate. This guarantees that the ball 620 can accurately block or disengage from the water outlet 311, improving the accuracy of water output control.

[0036] The top of the water outlet 311 has a spherical groove that fits the outer contour of the bottom of the ball 620. This spherical groove design allows for better matching with the ball 620, forming a tighter seal when the ball 620 blocks the top of the water outlet 311, effectively preventing tea leakage. A cylinder 320 is located directly above the water outlet 311 on the valve seat 310. The inner cavity of the cylinder 320 above the water outlet 311 communicates with the inner cavity of the inner liner 300. The bottom of the valve stem 600 and the ball 620 are located inside the cylinder 320. The cylinder 320 provides guidance and restriction for the up-and-down movement of the valve stem 600 and the ball 620, making their movement more stable, and also protecting the valve stem 600 and the ball 620 from external impacts.

[0037] When tea needs to flow, a specific operation causes the ball 620 to rise and detach from the water outlet 311, thus enabling water to flow. For this purpose, in this embodiment, a follower magnet 630 is fixed to the top of the valve stem 610, and an opening / closing magnet 450 capable of lateral displacement is provided on the cover 400. When the opening / closing magnet 450 moves directly above the follower magnet 630, due to magnetic attraction, the opening / closing magnet 450 magnetically attracts the follower magnet 630, thereby causing the valve stem 600 to move upward, driving the ball 620 to detach from the water outlet 311, forming an opening control structure for the water outlet 311, allowing tea to flow from the inner liner 300 into the pot body 100. Compared to traditional mechanical operation or long-distance magnetic control, this magnetic control method has the advantages of simple operation and sensitive response, enabling more precise control of the opening and closing of the water outlet 311.

[0038] Furthermore, in combination Figure 5 and Figure 6 As shown, the cover 400 includes a disc-shaped panel 410. The top of the panel 410 has a sliding groove 411, which is a strip-shaped recessed groove with its inner end located at the center of the cover 400. The sliding groove 411 provides a track for the lateral movement of the opening and closing magnetic block 450. The bottom of the sliding groove 411 has a strip-shaped longitudinal through-hole 412, the length of which is parallel to the length of the sliding groove 411. An upper slider 420 is movably connected within the sliding groove 411, allowing it to slide linearly within the groove. The bottom of the upper slider 420 has a connecting rod 421, which extends through the through-hole 412 to the bottom of the panel 410 and connects to a lower slider 430. The connecting rod 421 has a threaded hole with an open bottom. Bolts are used to connect the lower slider 430 and the upper slider 420. After connection, the lower slider 430 is attached to the bottom of the cover 400, and the lower slider 430 and the upper slider 420 form a synchronous linkage structure. When the user pushes the upper slider 420 to move laterally within the sliding groove 411, the lower slider 430 will also move synchronously.

[0039] The opening and closing magnetic block 450 is located at the bottom inner end of the lower slider 430. As the lower slider 430 moves, its position changes (relative to the top of the valve stem 600), thereby achieving magnetic attraction or separation from the follower magnetic block 630.

[0040] The bottom of the panel 410 is connected to the bottom shell 460. The longitudinal profile of the bottom shell 460 is a U-shaped structure that is wider at the top and narrower at the bottom. The bottom shell 460 and the panel 410 enclose the lower slider 430 inside, which protects the lower slider 430 and the opening and closing magnetic block 450. It also avoids direct contact between the opening and closing magnetic block 450 and the follower magnetic block 630 during magnetic attraction. If the two are in direct contact, it will interfere with the subsequent lateral movement of the opening and closing magnetic block 450. At the same time, the bottom shell 460 also makes the entire cover 400 structure more compact and beautiful.

[0041] Additionally, a locking magnetic block 440 is provided between the lower slider 430 and the panel 410. The locking magnetic block 440 includes a first magnetic block 441 fixed to the bottom of the panel 410 and a second magnetic block 442 fixed to the lower slider 430. The second magnetic block 442 is located at the end of the lower slider 430 away from the closing magnetic block 450. When the lower slider 430 moves laterally to the threshold position following the upper slider 420, the second magnetic block 442 is located directly below the first magnetic block 441. At this time, a magnetic attraction limiting structure is generated between the first magnetic block 441 and the second magnetic block 442. This locking magnetic block 440 design can ensure that the lower slider 430 can stay stably after moving to a specific position, preventing the lower slider 430 from moving randomly in the non-operational state, ensuring the accuracy of the relative position of the opening and closing magnetic block 450 and the follower magnetic block 630, thereby improving the stability of magnetically controlled water dispensing. For example, when water dispensing is not required, such as... Figure 7 The left-side structure features a locking magnetic block 440 that keeps the sliding block 430 in a position that keeps the opening / closing magnetic block 450 away from the following magnetic block 630. This ensures sufficient distance between the opening / closing magnetic block 450 and the following magnetic block 630, preventing them from attracting each other and moving. The ball 620 is stably blocked above the water outlet 311. When water is needed, such as... Figure 7 In the right-side structure, when the user pushes the upper slider 420 horizontally inward, it causes the lower slider 430 to move to the threshold position. The first magnetic block 441 and the second magnetic block 442 of the locking magnetic block 440 are misaligned and do not attract each other, so that the opening and closing magnetic block 450 continuously attracts the following magnetic block 630, thus achieving stable water output.

[0042] Furthermore, such as Figure 8 As shown, a raised ridge 470 is provided on the bottom surface of the sliding groove 411 and the panel 410. The raised ridge 470 is located on the sliding path of the upper slider 420 and the lower slider 430. The raised ridge 470 is two parallel linear flange structures, and the length direction of the raised ridge 470 is parallel to the sliding direction of the upper slider 420 and the lower slider 430. The presence of the raised ridge 470 can play a number of roles. On the one hand, the raised ridge 470 reduces the contact area and friction by utilizing its raised structure, making the sliding of the upper slider 420 and the lower slider 430 smoother. On the other hand, the raised ridge 470 can provide a certain guiding effect for the sliding of the upper slider 420 and the lower slider 430, making them smoother and more accurate during the sliding process, reducing sliding deviation, and further improving the stability and reliability of the teapot operation.

[0043] This embodiment of a teapot based on a magnetic switch, through its unique structural design, including a rational layout of magnetic control components, a linkage structure of the lid 400, a locking magnetic block 440 design, a sliding guide structure, and related structural designs at the bottom of the inner liner 300, effectively solves the stability problem of existing teapots in terms of magnetic control effect. This teapot has advantages such as stable magnetic control effect, convenient operation, and a reasonable and reliable structural design, providing users with a higher quality and more efficient tea brewing experience. It has broad application prospects and market potential in the field of teaware, and is expected to promote the technological upgrading and innovative development of teapot products.
