Description

Technical Field

[0001] This utility model belongs to the technical field of products for people with disabilities, specifically relating to a magnetic easy-to-clean floating ruler water cup for the blind. Background Technology

[0002] People with visual impairments, such as the blind, face numerous inconveniences in their daily lives, with the use of a water cup being a typical example. Unable to visually judge the water level, they are prone to spilling liquids (especially hot water) when filling the cup, posing a risk of burns. Furthermore, they often struggle to gauge the remaining water level while drinking, negatively impacting their experience.

[0003] To address this issue, some existing technologies employ floating water level indicators. For example, a hollow tube is placed inside a cup, with a floating scale that rises and falls with the liquid level. A hole is located at the bottom of the tube, using the principle of communicating vessels to maintain consistent liquid levels inside and outside the tube. However, this design reveals two shortcomings in practical applications that urgently need to be addressed: When users use such cups to brew beverages containing solid particles, such as tea, traditional Chinese medicine, or fruit tea, these particles can easily be drawn into the pipe's holes during pouring or shaking, causing partial blockage. Once a blockage occurs, the exchange of liquid levels inside and outside the pipe is hindered, causing the floating scale to fail to accurately reflect the true water level, rendering the measurement function ineffective. Furthermore, there is a narrow gap between the floating scale and the inner wall of the pipe, and the holes in the pipe can easily trap liquid and dirt. If these areas are not cleaned promptly, bacteria can easily grow. For visually impaired users, it is difficult to perceive and thoroughly clean these complex, hard-to-clean areas, and long-term use may pose health risks. Even if the device is designed to be removable from the cup, its complex internal structure remains difficult to clean.

[0004] Therefore, how to provide a water cup for the blind that can ensure accurate measurement in any usage scenario and allows visually impaired users to easily and thoroughly clean it to ensure hygiene and safety is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The purpose of this invention is to provide a magnetically attached, easy-to-clean, floating ruler-type water cup for the blind, which aims to solve the technical problems of existing floating water level measuring devices being easily blocked by foreign objects, resulting in inaccurate measurements, and the complex structure that creates cleaning dead corners and breeds bacteria, posing hygiene risks.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A magnetic easy-to-clean floating ruler water cup for the blind includes a cup body, the main body of which is made of food-grade material and its inner wall surface is a smooth curved surface; The cup body is provided with a magnetic adsorption base inside the wall material of the cup body, and the magnetic adsorption base is embedded in the wall material of the cup body and does not come into direct contact with the liquid. The magnetic guide filter assembly includes a C-shaped filter frame with a "C"-shaped main body and magnetic units disposed inside the longitudinal edges on both sides of the C-shaped filter frame; The magnetically attracted guide filter assembly magnetically engages with the magnetic adsorption base on the cup body via the magnetic unit, thereby detachably adsorbing onto the inner wall of the cup body. In the adsorbed state, the inner concave surface of the C-shaped filter frame and the inner wall of the cup body together form a vertically extending closed guide channel. The C-shaped filter frame divides the internal space of the cup body into two areas: a guide area formed by the concave surface of the magnetically attracted guide filter assembly and the inner wall of the cup body, and a tea filtration area formed by the convex surface of the magnetically attracted guide filter assembly and the inner wall of the cup body. The C-shaped filter frame has filter holes on its side wall that connect the guide area and the tea filtration area; A water level measuring device, floatingly installed within the guide channel, includes a float and a ruler connected above the float, the ruler having Braille markings for touch recognition; In the disassembled state, the magnetic guide filter assembly separates from the cup body, the guide channel disintegrates, and the inner wall of the cup body and the surface of the C-shaped filter frame are both open and cleanable surfaces.

[0007] Furthermore, the longitudinal edges on both sides of the C-shaped filter frame are designed as outwardly expanding inverted trapezoidal flared structures; The magnetic suction unit is embedded inside the inverted trapezoidal flared structure; The magnetic adsorption base forms an elongated adsorption area on the side wall of the cup body that corresponds to the inverted trapezoidal flared structure. The inverted trapezoidal flared structure is configured to automatically center and adsorb the magnetically guided filter component by utilizing the inclined surface of the inverted trapezoidal flared structure in conjunction with the normal component of the magnetic attraction force.

[0008] Furthermore, the magnetic attraction unit includes a neodymium iron boron magnet core and a flexible sealing layer that completely covers the outside of the inverted trapezoidal flared structure; In the adsorption state, the flexible sealing layer is held by magnetic attraction and undergoes elastic deformation, sealing the gap between the edge of the C-shaped filter frame and the inner wall of the cup. The flexible sealing layer is made of food-grade liquid silicone.

[0009] Furthermore, the ruler is made of food-grade silicone and has elastic memory properties. It can bend elastically when touched by a lateral external force and automatically return to a vertical state after the external force is removed. The top of the ruler is designed with a smooth, obtuse angle structure; The planar shape of the float is an ellipse that matches the cross-section of the guide channel.

[0010] Furthermore, a duckbill-shaped water inlet is provided on the upper side wall of the cup body corresponding to the guide area, and the inner cavity of the water inlet is directly connected to the guide channel; The connection between the water inlet and the guide channel is equipped with a two-stage filter.

[0011] Furthermore, it also includes a cup lid, which is detachably fitted onto the top of the cup body; The lower surface of the cup lid is provided with a downwardly protruding C-shaped limiting rib, the shape of which matches the top cross-sectional shape of the C-shaped filter frame; When the cup lid is closed, the C-shaped limiting rib is held in place at the top of the C-shaped filter frame.

[0012] Furthermore, the overall outline of the cup lid covers and is larger than the upper opening of the tea filtering area and the guide area; The cup lid is provided with a through hole or opening corresponding to the guide channel for the ruler rod to pass through, and the size of the opening is smaller than the size of the float, so as to prevent the water level measuring device from detaching from the cup body when the water level is too high.

[0013] Furthermore, the connection structure between the cup lid and the cup body is a direct-fitting structure or a short-stroke locking and rotating structure.

[0014] Furthermore, the magnets in the magnetic adsorption base and magnetic adsorption unit are neodymium iron boron magnets; The magnetic adsorption base is sealed inside the wall of the cup, and the magnetic adsorption unit is sealed inside the inverted trapezoidal flared structure.

[0015] Furthermore, the cup body is made of polyphenylsulfone, and the C-shaped filter frame is made of food-grade polypropylene.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) This utility model provides a magnetic easy-clean floating ruler water cup for the blind. When cleaning is required, the user only needs to remove the magnetic guide filter component. There are no deep holes or gaps that cannot be reached by fingers or cleaning tools. Blind users can easily clean without dead angles, eliminating the hidden danger of bacterial growth from the root.

[0017] (2) This utility model provides a magnetic easy-clean floating scale water cup for the blind, which uses the large side wall of the C-shaped filter frame as the primary filter and a secondary filter at the water inlet to effectively block tea residue. The large water passage ensures the effectiveness of the communicating vessel principle and guarantees the reliability of water level measurement.

[0018] (3) This utility model provides a magnetic easy-clean floating ruler water cup for the blind. The inverted trapezoidal magnetic structure has an automatic guiding function, allowing the blind to complete the installation of the components without precise alignment. The ruler is also made of food-grade silicone material, which has anti-collision and bending functions to prevent the hard ruler from puncturing the blind person's face. The magnet is fully enclosed and sealed to prevent contact with liquid. Attached Figure Description

[0020] The technical solution of this utility model will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are not all embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] It should be noted that the terms "center", "upper", "lower", "horizontal", "left", "right", "front", "back", "lateral", "longitudinal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] This embodiment provides a magnetic easy-to-clean water cup specifically designed for visually impaired individuals, such as... Figures 1 to 4 As shown, it mainly includes a cup body 1, a magnetic guide filter assembly 2, a water level measuring device 3, and a cup lid 4.

[0023] The main body of the cup body 1 is made of food-grade polyphenylene sulfone (PPSU), which is heat-resistant, impact-resistant, and BPA-free. As shown in the figure, the cup body 1 is generally cylindrical or slightly conical in shape. Regarding the grip structure of the cup body, the cup body 1 can be designed with a handle or without a handle. In this embodiment, a handle is designed on the outer wall of the cup body 1 to facilitate a stable grip for blind users. However, in other preferred embodiments, to simplify the structure or adapt to different usage habits, the cup body 1 may not have a handle.

[0024] Inside the cup body 1, there are two elongated storage slots along the vertical direction, such as... Figure 1 As shown in the black area, a magnetic adsorption base 11 is embedded in the groove. In this embodiment, the magnetic adsorption base 11 is a long strip of neodymium iron boron magnet. Neodymium iron boron magnets are heat-resistant (temperature resistance above 120℃) and will not demagnetize when the water temperature is high. Furthermore, for aesthetic purposes and to protect the magnet from corrosion, after embedding the magnet, it is sealed by ultrasonic welding, ensuring that the outer surface of the cup body 1 remains completely flat and smooth, and that the magnet does not directly contact the liquid inside the cup. In addition, a duckbill-shaped water inlet 12 extending outwards is provided on the upper side wall of the cup body 1. The curvature of the water inlet 12 is set to be relatively gentle to fit the lip and prevent it from pricking the mouth when drinking. A secondary filter hole 121 with a diameter of approximately 0.5mm is provided at the base of the water inlet 12 where it connects to the internal space of the cup, for secondary filtration when pouring liquid.

[0025] Magnetic guide filter component 2, such as Figure 2 and Figure 3As shown, the main body of the component is a micro-"C"-shaped C-type filter frame 21, made of food-grade PP. The arc-shaped sidewalls of the C-type filter frame 21 are densely covered with filter holes 210 with a diameter of approximately 1 mm. These filter holes 210 allow liquid to pass through freely, but solid particles such as tea leaves are blocked; this is the primary filtration structure in this embodiment. The longitudinal edges on both sides of the C-type filter frame 21 are designed as outwardly expanding inverted trapezoidal flared structures 211. Inside each inverted trapezoidal flared structure 211, a magnetic suction unit is encapsulated using an insert injection molding process. The magnetic suction unit also uses neodymium iron boron magnet core material, and a thin flexible sealing layer covers the sides of the C-type filter frame 21, i.e., the exterior of the inverted trapezoidal flared structures 211. In this embodiment, the flexible sealing layer is preferably made of food-grade liquid silicone. When the magnetically guided filter assembly 2 is placed in the cup, the magnetic suction unit attracts the magnetic adsorption base 11 inside the cup wall. At this point, the magnetic surface of the inverted trapezoidal flared structure 211 should be the same size as the area of ​​the elongated magnet inside the magnetic adsorption base 11. This makes it easier to coordinate with the normal component of the magnetic force for automatic adsorption, assisting blind users in easily installing the magnetically guided filter assembly 2 into place. Meanwhile, the flexible sealing layer on the outer layer of the C-shaped filter frame 21 undergoes elastic deformation under magnetic clamping, tightly adhering to the inner wall of the cup body 1, resulting in a tighter fit and preventing tea residue from leaking in through side gaps.

[0026] In the adsorption state, the inner concave surface of the magnetic guide filter component 2 and the smooth inner wall of the cup body 1 together form a vertical guide channel. The magnetic guide filter component 2 divides the internal space of the cup body into two areas: the guide area formed by the concave surface of the magnetic guide filter component 2 and the inner wall of the cup body 1, and the tea filtration area formed by the convex surface of the magnetic guide filter component 2 and the inner wall of the cup body 1.

[0027] Water level measuring device 3, such as Figures 1 to 3 As shown, the device is floating within the guide channel. It includes a bottom float 31 and a top ruler 32. The float 31 is a hollow PP buoy with an elliptical shape adapted to the cross-section of the guide channel, and a suitable gap is left between it and the inner wall of the channel to prevent jamming. One end of the ruler 32 is fixed to the float 31, and the other end extends upward. To protect the safety of visually impaired users, the ruler 32 in this embodiment is specially made of food-grade silicone. This material has good flexibility and elastic memory. When a blind person bends down to drink water and their face accidentally touches the ruler 32, the ruler will bend elastically without any pain; and when the external force is removed, the ruler will return to its vertical state due to the elasticity of the material and continue to indicate the water level. The surface of the ruler 32 is molded with raised Braille markings 33 for the user to read by touch.

[0028] Cup lid 4, as Figure 4As shown, the inner bottom surface of the cup lid 4 is provided with a ring of downward-protruding C-shaped limiting ribs 41. When the cup lid 4 is closed, the C-shaped limiting ribs 41 press precisely against the upper surface of the C-shaped filter frame 21. This design forms a stable structure with magnetic radial fixation and axial pressing of the cup lid. In addition, the overall outline of the cup lid 4 covers and is slightly larger than the tea filtering area, and also covers the guide area. The cup lid 4 has an opening at the guide channel for the measuring rod to extend, but the size of this opening is smaller than the size of the float 31. This feature can prevent the water level measuring device 3 from falling out of the cup with the overflowing water if too much water is poured in. The protruding part of the cup lid can limit the float 31.

[0029] Regarding the closing method of the cup lid 4, this embodiment provides two optional structures: the first is a direct closing structure, that is, the cup lid 4 is closed on the cup mouth by gravity or slight friction, which is convenient and quick to use and suitable for static use at home.

[0030] The second type is a short-stroke locking and rotating structure, in which the lid 4 and the cup opening are fitted with a latch or rotor. The user only needs to put down the lid 4 and rotate it for a short stroke to lock the lid. This structure ensures a tight fit while also taking into account the convenience of blind operation, avoiding the difficulty of aligning long threads.

[0031] The working principle of this invention is as follows: Utilizing the principle of communicating vessels, when water is poured into the cup body 1, the liquid passes through the filter holes 210 on the C-shaped filter frame 21 and enters the guide channel, making the liquid surface in the guide area and the tea filtration area level. Tea leaves are blocked from the outside. The water level measuring device 3 floats with the liquid level and indicates the water level via a flexible ruler 32. After drinking, the cup lid 4 and the magnetic guide filter assembly 2 can be removed to thoroughly clean the fully open inner wall of the cup and the surface of the assembly.

[0032] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
