Abstract
Description
[Technical Field]
[0001] This utility model relates to the field of coaster technology, specifically a magnetically levitated self-drying coaster. [Background Technology]
[0002] In existing technologies, traditional reusable coasters, such as those made of silicone, plastic, wood, or ordinary felt, primarily rely on the absorbency and heat insulation properties of the materials to achieve their basic functions. These products require manual washing and separate air drying after use, a time-consuming and space-consuming process. Furthermore, most traditional coaster materials are not recyclable or biodegradable, making them environmentally unfriendly after disposal. In terms of function and user experience, existing products have simplistic designs, lack technological innovation, and fail to provide additional user enjoyment or health benefits while fulfilling basic functions.
[0003] Therefore, the market urgently needs an innovative coaster product that can automatically dry, is environmentally friendly, and combines fun with a healthy concept. [Utility Model Content]
[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a magnetic levitation self-drying coaster that can automatically dry, is environmentally friendly, and combines fun with a healthy concept. It solves the problems of traditional coasters, such as inconvenience in drying after washing, limited functionality, and poor environmental performance.
[0005] To achieve the above objectives, a magnetic levitation self-drying coaster is designed, comprising a felt coaster 1, a levitation module 2, and an annular base 3. The levitation module 2 is fixed inside the center of the felt coaster 1. The levitation module 2 adopts a fully sealed design and has a single-pole magnet structure inside. The center of the levitation module 2 has a through hole 204. The top of the annular base 3 has a hollow stainless steel column 301. A cylindrical neodymium magnet 302 is embedded inside the hollow stainless steel column 301. The polarity of the cylindrical neodymium magnet 302 is the same as the magnetic pole of the levitation module 2. The levitation module 2 is fitted into the hollow stainless steel column 301 through the through hole 204 in its center.
[0006] Furthermore, the center of the felt coaster 1 is provided with a tenon and mortise structure interface 101 that is interference-fitted with the shape of the suspension module 2, and the suspension module 2 is embedded inside the felt coaster 1 through the tenon and mortise structure interface 101.
[0007] Furthermore, the center of the felt coaster 1 is provided with a fitting interface 102 that is interference-fitted with the shape of the suspension module 2, and the suspension module 2 is pressed into the fitting interface 102 of the felt coaster 1 in an interference fit manner.
[0008] Furthermore, the felt coaster 1 is made of recyclable wool felt material, thus overcoming the problem that most traditional coaster materials are not recyclable and are environmentally unfriendly after disposal.
[0009] Furthermore, the levitation module 2 is composed of a neodymium magnet 201 and a large metal disk 202. The neodymium magnet 201 is located on the upper and lower sides of the large metal disk 202, so that the upper and lower surfaces of the levitation module 2 have the same magnetic poles. The outer layer of the levitation module 2 is sealed with a biodegradable plastic sealing layer 203, which further solves the problem of environmental unfriendliness after disposal due to the difficulty in degrading the material.
[0010] Furthermore, the biodegradable plastic sealing layer 203 is made of food-grade heat-resistant PLA plastic, and the suspension module 2 is encapsulated by food-grade heat-resistant PLA plastic to form a fully sealed cylindrical module, thereby ensuring the safety of use.
[0011] Furthermore, the hollow stainless steel column 301 is made of hollow stainless steel tube. A cylindrical neodymium magnet 302 is pressed and fixed inside the hollow stainless steel column 301. A stainless steel column bottom cover 303 is installed at the bottom of the hollow stainless steel column 301. Thus, the cylindrical magnet inside the column can generate a sufficiently strong magnetic repulsion force with the floating module at the bottom of the coaster. At the same time, the stainless steel material provides good structural support and protection.
[0012] Furthermore, the bottom of the annular base 3 is designed in the shape of a gyroscope, a flying saucer, or a dome. The bottom of the annular base 3 is connected to the hollow stainless steel column 301 by bolts 304, thus achieving a clean appearance without redundant details.

[0017] (4) The passive levitation vortex posture and spring-like bouncing effect generated by this utility model during operation constitute its unique and copyright-protected dynamic aesthetic features, and its dynamic visual effect is excellent.
[0018] (5) The structure of this utility model is stable and safe. Its fully sealed design ensures that the internal magnet does not come into contact with the outside world, and the food-grade heat-resistant shell ensures the safety of use.
[0019] (6) The base of this utility model adopts a design of stainless steel column with embedded cylindrical magnet, which not only provides precise magnetic guidance and strong repulsive force, but also enhances the durability and stability of the structure.

[0028] The present invention will be further described below with reference to the accompanying drawings:
[0029] As attached Figure 1 To be continued Figure 11As shown, this utility model provides a magnetic levitation self-drying coaster, including a felt coaster 1, a levitation module 2, and an annular base 3. The levitation module 2 is fixed inside the center of the felt coaster 1. The levitation module 2 adopts a fully sealed design and has a single-pole magnet structure inside. The center of the levitation module 2 is provided with a through hole 204. The top of the annular base 3 is provided with a hollow stainless steel column 301. A cylindrical neodymium magnet 302 is embedded inside the hollow stainless steel column 301. The polarity of the cylindrical neodymium magnet 302 is the same as the magnetic pole of the levitation module 2. The levitation module 2 is fitted into the hollow stainless steel column 301 through the through hole 204 in its center.
[0030] The felt coaster 1 is made of recyclable wool felt, thus overcoming the problem that most traditional coaster materials are not recyclable and are environmentally unfriendly after disposal. The center of the felt coaster 1 is provided with a tenon and mortise structure interface 101 that is interference-fitted with the shape of the suspension module 2. The suspension module 2 is embedded into the inside of the felt coaster 1 through the tenon and mortise structure interface 101. Alternatively, the center of the felt coaster 1 is provided with a fitting structure interface 102 that is interference-fitted with the shape of the suspension module 2. The suspension module 2 is pressed into the fitting structure interface 102 of the felt coaster 1 in an interference fit manner.
[0031] The levitation module 2 is composed of neodymium magnets 201 and a large metal disk 202. The neodymium magnets 201 are located on the upper and lower sides of the large metal disk 202, so that the upper and lower surfaces of the levitation module 2 have the same magnetic poles. The outer layer of the levitation module 2 is sealed with a biodegradable plastic sealing layer 203, which further solves the problem of environmentally unfriendly disposal due to the material's difficulty in degradation. The biodegradable plastic sealing layer 203 is made of food-grade heat-resistant PLA plastic. The levitation module 2 is encapsulated by food-grade heat-resistant PLA plastic to form a fully sealed cylindrical module, thereby ensuring the safety of use.
[0032] The bottom of the ring-shaped base 3 is designed in the shape of a gyroscope, flying saucer, or dome. The bottom of the ring-shaped base 3 is connected to the hollow stainless steel column 301 by bolts 304, resulting in a clean appearance without redundant details. The hollow stainless steel column 301 is made of hollow stainless steel tube. A cylindrical neodymium magnet 302 is pressed and fixed inside the hollow stainless steel column 301. A stainless steel column bottom cover 303 is installed at the bottom of the hollow stainless steel column 301, so that the cylindrical magnet inside the column can generate a sufficiently strong magnetic repulsion force with the floating module at the bottom of the coaster. At the same time, the stainless steel material provides good structural support and protection.
[0033] The magnetic levitation self-drying coaster described in this utility model aims to solve the problems of traditional coasters, such as inconvenience in drying after washing, limited functionality, and poor environmental friendliness. The product consists of three core components: a felt coaster 1, a suspension module 2, and a ring-shaped base 3. The felt coaster 1 is made of recyclable wool felt and has a tenon-and-mortise joint 101 in its center for fixing the suspension module 2. The suspension module 2 is embedded inside the felt coaster 1 through the tenon-and-mortise joint 101. The module adopts a fully sealed and heat-resistant design. Its core is an innovative unipolar magnet structure, which is composed of a neodymium magnet 201 with opposite poles and a large metal disc 202, so that the upper and lower surfaces of the module have the same magnetic poles (e.g., both are N poles). The outer layer of the module is completely sealed with food-grade heat-resistant and biodegradable thermoplastic plastic and has a through hole 204 in the center. The top of the ring-shaped base 3 has a hollow stainless steel column 301. A cylindrical neodymium magnet 302 is embedded inside the column, and the polarity of the cylindrical magnet is specially set so that it is the same as the magnetic pole of the suspension module 2 (e.g., both are N poles), thereby generating a mutual repulsion effect. The hollow stainless steel column 301 adopts a hollow stainless steel tube design with a cylindrical neodymium magnet 302 precisely pressed inside. This structural design ensures that when the first coaster is inserted into the column through its central through hole 204, the cylindrical magnet 302 inside the column can generate a sufficiently strong magnetic repulsion force with the floating module 2 at the bottom of the coaster. At the same time, the stainless steel material provides good structural support and protection.
[0034] The working principle of this utility model is as follows: the assembled coaster is inserted into the hollow stainless steel column 301 of the base through the central through hole 204; since the suspension module 2 and the cylindrical neodymium magnet 302 embedded in the base column have the same magnetic poles, a strong repulsive force is generated, which overcomes the coaster's own weight and makes it stably suspended above the base; under the combined action of magnetic balance and air disturbance, the coaster will undergo a slow, non-contact vortex motion; this motion accelerates the air flow on the surface of the coaster, thereby achieving rapid natural air drying; when a container filled with liquid is placed, the strong magnetic field generated by the coaster can also magnetize the liquid in the container.
[0035] The magnetic levitation self-drying coaster described in this utility model can be implemented in the following way:
[0036] First, the levitation module 2 is prepared. A ring-shaped neodymium magnet with its magnetization direction along the axis and the same polarity on its upper and lower surfaces is fixedly bonded to a metal disk with good magnetic permeability (such as low carbon steel) to form a unipolar magnet structure. This assembly is placed in an injection mold and encapsulated with food-grade heat-resistant PLA plastic to form a fully sealed cylindrical module with a through hole machined in the center.
[0037] Next, the felt coaster 1 is prepared. A circular recyclable wool felt pad is used, and a mortise and tenon structure interface that is interference-fitted with the shape of the suspension module 2 is punched out at its center using a precision mold, or an insert structure interface that is interference-fitted with the shape.
[0038] Next, prepare the annular base 3. Use a stainless steel tube to precisely machine a hollow column, press a cylindrical neodymium magnet with the same polarity as the magnetic pole of the suspension module into the stainless steel column and fix it, and install the assembled column assembly into the base shell.
[0039] Finally, the coaster is assembled and used. The packaged suspension module 2 is pressed into the tenon or mortise joint or the insert-type structural joint of the felt coaster 1 with an interference fit to form a coaster unit. When in use, the user aligns the center through hole at the bottom of the coaster unit with the hollow stainless steel column of the base and slowly inserts it. Due to the mutual repulsion between the cylindrical magnet inside the column and the coaster suspension module, the coaster will automatically and stably levitate and begin to slowly rotate, thus achieving the self-drying function.
