Description

Technical Field

[0001] This invention relates to the field of age-friendly daily necessities, specifically to an age-friendly anti-shake mouthwash cup. Background Technology

[0002] Mouthwash cups are indispensable oral care products in daily life, serving to hold mouthwash and assist users in cleaning their mouths. However, due to declining physiological functions (such as low-frequency hand tremors, decreased grip strength, and weakened coordination), older adults face numerous difficulties when using traditional mouthwash cups, including spillage, unstable grip, and potential safety hazards. Therefore, some basic improved versions of age-appropriate water cups have emerged on the market, primarily focusing on structural adjustments such as larger handles and added anti-slip textures. Additionally, a small number of nursing cups designed for specific scenarios exist, such as drinking cups with long-outlet spouts suitable for bedridden elderly individuals.

[0003] However, age-friendly mouthwash cups designed for the general elderly population (including those with hand tremors and weakened grip strength) have at least the following shortcomings: (1) The existing product's technical solutions only focus on basic improvements such as enlarging the handle and adding anti-slip textures, which cannot fundamentally solve the problem of liquid spillage caused by hand tremors; (2) Ordinary mouthwash cups do not take into account the actual situation of the elderly, resulting in a poor user experience; while nursing products are limited to the bedridden scenario and have a single function; and similar elderly-friendly water cups generally confuse the difference between drinking water and mouthwash scenarios, and cannot meet the needs of the vast majority of elderly people to stand up and rinse their mouths independently. (3) Existing products only address local issues such as leak prevention and slip prevention, which is insufficient to meet the multiple needs of the elderly for safety and comfort. (4) Existing smart anti-shake products have drawbacks such as high cost and complicated operation, making it difficult to popularize on a large scale; while mouthwash cups, as daily necessities for the elderly, have long been neglected in terms of age-friendly design. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an age-friendly, vibration-resistant mouthwash cup that solves the problem of water splashing caused by low-frequency vibration through the cooperation between the inner cup body, the outer cup shell, and the buffer component.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An age-friendly, vibration-resistant mouthwash cup includes a cup shell, a cup body embedded inside the cup shell, an upper end of the cup body extending to the outer side of the cup shell and folding outward to form a shielding part, an upper end of the cup shell being embedded between the shielding part and the cup body, and a buffer assembly provided between the cup body and the cup shell, the buffer assembly being used to buffer the vibration of the cup body relative to the cup shell, and the buffer assembly being centrally symmetrically distributed with respect to the axis of the cup body.

[0006] Optionally, the outer wall of the cup body is provided with a first protrusion, and the inner wall of the cup shell is provided with a second protrusion corresponding to the number and position of the first protrusion. The two ends of the buffer assembly are respectively connected to the corresponding first protrusion and the second protrusion.

[0007] Optionally, the buffer assembly is provided in multiple layers along the axis of the cup body, the multiple layers of the buffer assembly are distributed at intervals along the axis of the cup body, and the buffer assembly is made of spring.

[0008] Optionally, the top of the cup body has a rim, and a cap is embedded in the rim, with both the cap and the top surface of the shielding part being curved.

[0009] Optionally, after the cup cap is inserted into the cup opening, the top surface of the cup cap and the top surface of the shielding part are on the same spherical surface.

[0010] Optionally, the cup cap has an insertion hole that communicates with the inner cavity of the cup body.

[0011] Optionally, the bottom surface of the cup shell is provided with a bottom hole, which communicates with the inner cavity of the cup shell.

[0012] Optionally, the portion of the cup body embedded inside the cup shell adopts a cylindrical structure, and the radial dimension of the cup shell gradually increases axially from the opening end to the bottom surface.

[0013] Optionally, a finger ring is provided on the outer wall of the cup shell. The finger ring has an elliptical structure and is integrally formed and connected to the cup shell.

[0014] Optionally, the inner side of the ring is provided with multiple anti-slip protrusions.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In this invention, the inner cup body is connected to the outer cup shell through a buffer assembly. The inner cup body is used to hold water. When hand tremors are transmitted to the outer cup shell, the buffer assembly absorbs the tremor kinetic energy through elastic deformation. At the same time, it uses a centrally symmetrical layout to achieve uniform buffering, so that the inner cup body remains relatively still and suppresses the water from overflowing due to inertial shaking, thereby solving the problem of water splashing out due to low-frequency tremors. (2) In this invention, the shielding part extends to the outside of the cup shell, so that the upper end of the cup shell is embedded between the shielding part and the cup body. This structure is not only aesthetically pleasing, but also can shield the opening end of the cup shell to prevent foreign matter from entering the cup shell and causing pollution. (3) In this invention, when the mouthwash cup is in use, the thumb can be inserted into the oval ring and the other fingers can naturally wrap around the outer shell of the cup. By utilizing the relatively stable range of motion and force point of the thumb, a passive locking effect is formed. There is no need to continuously exert force. Even if there is low-frequency vibration in the hand, the ring can limit the displacement of the cup relative to the hand and prevent the cup from slipping. (4) In this invention, the mouthwash cup adopts a mushroom-shaped curve design, which can avoid the risk of bumping the corners and meet the multiple needs of the elderly for safety and comfort.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention and therefore only show the components relevant to the present invention.

[0018] Example 1, such as Figures 1-5 As shown, an age-friendly anti-vibration mouthwash cup includes a cup body 1, a cup shell 2, a cup cap 4, a cushioning component, and a finger ring 6. The cup body 1 is embedded inside the cup shell 2. The upper end of the cup body 1 extends to the outer side of the cup shell 2 and folds outward to form a shielding part 3. The cushioning component is disposed between the cup body 1 and the cup shell 2. The finger ring 6 is disposed on the outer side of the cup shell 2 and located below the shielding part 3. The cushioning component is used to cushion the vibration of the cup body 1 relative to the cup shell 2. The cushioning component is centrally symmetrically distributed with respect to the axis of the cup body 1. The cup cap 4 is embedded at the mouth of the cup body 1.

[0019] The inner cup 1 is connected to the outer cup shell 2 through a buffer assembly. The inner cup 1 is used to hold water. When hand tremors are transmitted to the outer cup shell 2, the buffer assembly absorbs the kinetic energy of the tremors through elastic deformation. At the same time, it uses a centrally symmetrical layout to achieve uniform buffering, keeping the inner cup 1 relatively still and suppressing the water from overflowing due to inertial shaking, thereby solving the problem of water splashing out due to low-frequency tremors.

[0020] As described above, the upper end of the cup shell 2 is embedded between the shielding part 3 and the cup body 1, that is, when the upper end of the cup body 1 is folded outward, it faces downward, so that the shielding part 3 is fitted on the outside of the cup body 1, so as to ensure that the upper end of the cup shell 2 can be embedded between the two; the shielding part 3 extends to the outside of the cup shell 2, so that the upper end of the cup shell 2 is embedded between the shielding part 3 and the cup body 1. This structure is not only aesthetically pleasing, but also can shield the opening end of the cup shell 2 to prevent foreign matter from entering the cup shell 2 and causing pollution.

[0021] The ring 6 on the outer wall of the cup shell 2 is located in the middle of the cup shell 2. The ring 6 has an oval structure and is integrally formed with the cup shell 2. When using the mouthwash cup, the user can insert the thumb into the oval ring 6 and the other fingers naturally wrap around the outer cup shell 2. By utilizing the relatively stable range of motion and force point of the thumb, a passive locking effect is formed. There is no need to continuously exert force. Even if there is low-frequency tremor in the hand, the ring 6 can limit the displacement of the cup body 1 relative to the hand and prevent the cup body 1 from slipping.

[0022] To improve the anti-slip performance of the ring 6, multiple anti-slip protrusions 601 are provided on the inner side of the ring 6, and the anti-slip protrusions 601 protrude from the inner side of the ring 6.

[0023] Furthermore, the outer wall of the cup body 1 is provided with a first protrusion 101, and the inner wall of the cup shell 2 is provided with a second protrusion 202 corresponding to the number and position of the first protrusion 101. The two ends of the buffer assembly are respectively connected to the corresponding first protrusion 101 and second protrusion 202, and the axis of the buffer assembly is perpendicular to the axis of the cup body 1.

[0024] The buffer assembly can be a spring 5. The first protrusion 101 and the second protrusion 202 are provided with mounting holes. The two ends of the spring 5 can pass through the mounting holes and be connected to the first protrusion 101 and the second protrusion 202 respectively, thereby realizing the connection between the inner cup body 1 and the outer cup shell 2, and ensuring that the axis of the buffer assembly is perpendicular to the axis of the cup body 1.

[0025] Furthermore, in order to improve the stability of the connection between the cup body 1 and the cup shell 2, the buffer assembly here is provided in multiple layers along the axis of the cup body 1, and the multiple layers of buffer assembly are distributed at intervals along the axis of the cup body 1. This can not only ensure the stability of the cup body 1 installed inside the cup shell 2, but also improve the anti-shake performance of the mouthwash cup and reduce the risk of water splashing due to the user's hand tremors.

[0026] The age-friendly, anti-shake mouthwash cup proposed in this application has its opening located at the top of the cup body 1. The opening adopts an arc-shaped structure design, and the top surfaces of both the cup cap 4 and the shielding part 3 are curved. When the cup cap 4 is inserted into the opening, the top surfaces of the cup cap 4 and the shielding part 3 are on the same spherical surface. This structure not only ensures the sealing of the inner cavity of the cup body 1, preventing dust and other debris from entering the inner cavity of the cup body 1, but also gives the mouthwash cup a rounded shape, reducing the risk of bumps and knocks, providing visual comfort for users, and improving their user experience.

[0027] Furthermore, the cup cap 4 has an insertion hole 401 that communicates with the inner cavity of the cup body 1, enabling the mouthwash cup to have a toothbrush storage function, thus solving the problems of limited functionality and inconvenient cleaning of existing products.

[0028] The bottom surface of the cup shell 2 has a bottom hole 201, which communicates with the inner cavity of the cup shell 2. During cleaning and use, if water or mouthwash accidentally seeps between the inner and outer layers of the mouthwash cup, raising the bottom hole 201 allows for rapid drainage of the accumulated water. This prevents mold growth, odor, and corrosion of the internal buffer components of the cup shell 2 caused by long-term water accumulation, effectively ensuring hygiene and reducing the risk of oral infections.

[0029] Meanwhile, if the water accumulated in the interlayer is not drained in time, it will increase the weight of the mouthwash cup and increase the burden on the elderly to hold it. The bottom hole 201 can drain the water in time, maintain the designed weight ratio of the mouthwash cup, ensure the stability of the inner cup body 1 to prevent shaking, and avoid tilting or liquid spillage when holding it due to weight imbalance.

[0030] Furthermore, the portion of the cup body 1 embedded inside the cup shell 2 adopts a cylindrical structure. The radial dimension of the cup shell 2 gradually increases axially from the opening end to the bottom surface. That is, the cup shell 2 adopts a structure that is smaller at the top and larger at the bottom. Its outer diameter at the opening end is smaller than the outer diameter at the bottom surface, and the wall thickness of the cup body 1 and the cup shell 2 is uniform.

[0031] Based on the structural design of the cup shell 2, the shielding part 3, and the cup cap 4, the age-friendly anti-vibration mouthwash cup has an overall mushroom-shaped structure. This not only solves the problem of water splashing caused by low-frequency vibration, but also avoids the risk of bumping into sharp corners, meeting the multiple needs of the elderly for safety and comfort.

[0032] Furthermore, the age-friendly, vibration-resistant mouthwash cup proposed in this invention has the following parameters: Inner diameter (D) of ring 6: The size of ring 6 that fits the thumb, ranging from 22 to 28 mm; Spring constant (k): Affects the damping effect of low-frequency vibration, ranging from 0.5 to 1.2 N / mm; Mouthwash cup outer diameter (Φ): the maximum outer diameter of the outer cup shell 2, ranging from 55-60mm; Cup body height (H): The total height from the bottom of the cup to the top of the cup cap 4, ranging from 80-90mm; Splash prevention rate (η): The proportion of water that does not splash out during rinsing out of the total amount of water; Slip rate (γ): The percentage of times the cup body 1 accidentally slips out of 100 uses.

[0033] Working principle: When elderly users use this mouthwash cup, they first insert their thumb into the grip structure (finger ring 6), and the other fingers naturally wrap around the area of ​​the outer cup shell 2 to form a passive and stable grip. This prevents the cup body 1 from slipping due to low-frequency vibrations without the need for continuous force. When the hand vibrates, the vibration energy transmitted by the outer cup shell 2 is absorbed by the centrally symmetrical spring 5 through elastic deformation, and the inner cup body 1 remains relatively still, effectively reducing water sloshing and leakage. The cup cap 4 not only provides dust protection and toothbrush storage, but also enhances the warm and inviting appearance. The modular design facilitates cleaning and maintenance. All the technical means work together to comprehensively solve the problems of unstable grip and water splashing in existing products.

[0034] Example 2: Based on Example 1, the present invention proposes an age-friendly anti-shake mouthwash cup, the grip structure of which can also adopt an adjustable elastic finger ring 6 with an adjustable inner diameter range of 20-30mm; the buffer component can adopt a food-grade silicone damper (damping coefficient 0.6N・s / mm) with a centrally symmetrical distribution; the other parameters are the same as in Example 1.

[0035] The performance test results of this embodiment are as follows: slippage rate: 2.5%; single splash volume: 2.2ml; splash resistance rate: 98.9%; grip comfort score: 9.0 points. The splash resistance effect of this alternative solution is comparable to that of the embodiment, and the ring 6 has better adaptability and quieter operation, proving that the alternative technical solution of the present invention can also achieve the purpose of the invention.

[0036] Example 3: Based on Example 1, the inner cup body 1 is made of food-grade PP plastic with an outer diameter of 58mm, a height of 70mm, a cup mouth diameter of 50mm, a cup mouth arc radius of 9mm, and a wall thickness of 2mm; the outer cup shell 2 is made of food-grade PP plastic with an outer diameter of 58mm and a height of 75mm; the finger ring 6 (grip structure) is made of food-grade PP+TPU coating, is elliptical, has an inner diameter of 25mm, a minor axis of 20mm, a wall thickness of 2.5mm, and a TPU coating thickness of 0.8mm; the buffer component is a cylindrical helical spring 5 with an elastic coefficient of 0.8N / mm, a free length of 22mm, a working stroke of 6mm, and a wire diameter of 1.2mm; the cup cap 4 is made of food-grade liquid silicone with a diameter of 60mm, a height of 15mm, and a top insertion hole 401 with a diameter of 13mm.

[0037] The inner cup body 1 and the outer cup shell 2 are injection molded, the ring 6 and the outer cup shell 2 are integrally injection molded, the anti-slip protrusion 601 on the inner side of the ring 6 are injection molded simultaneously, and the mushroom-shaped cup cap 4 is molded with silicone. The end of the spring 5 near the cup body 1 is fixed to the first protrusion 101 on the outer side of the inner cup body 1, and the end near the cup shell 2 is fixed to the second protrusion 202 on the inner side of the outer cup shell 2, ensuring that the two springs 5 ​​are centrally symmetrical (with an included angle of 180°) and the assembly tolerance is ±0.5mm. Then, the cup cap 4 is inserted into the cup mouth without loosening. The final product weighs 120g. After assembly, a leakage test is performed (tilted at 45° and held for 5 minutes, no leakage).

[0038] The performance test results of this embodiment are as follows: slip rate (γ): 3.0%; single splash volume: 2.0ml; splash resistance rate (η): 90%; grip comfort score: 8.5 points (out of 10); independent cleaning completion rate: 82%.

[0039] Example 4, based on Example 1, has the following specific parameters: The inner diameter (D) of the ring 6 is 22mm, the elastic coefficient (k) of the spring 5 is 0.5N / mm, the outer diameter (Φ) of the cup body 1 is 55mm, the height (H) of the cup body 1 is 80mm, the diameter of the inner cup mouth is 49mm, and the free length of the spring 5 is 20mm.

[0040] This embodiment uses minimum parameters to suit people with small hands. The materials and manufacturing processes of the remaining components are the same as in Embodiment 3. The performance test results are as follows: Slip rate (γ): 3.5%; Single splash volume: 2.8ml; Splash prevention rate (η): 86%; Grip comfort rating: 8.0 points; Independent cleaning completion rate: 85%.

[0041] Example 5, based on Example 1, has the following specific parameters: The inner diameter (D) of the ring 6 is 28mm, the spring elastic coefficient (k) is 1.2N / mm, the outer diameter (Φ) of the cup 1 is 60mm, the height (H) of the cup 1 is 90mm, the diameter of the inner cup opening is 52mm, and the free length of the spring 5 is 25mm.

[0042] This embodiment uses the maximum parameter, which is suitable for people with large hands / weak grip strength. The materials and manufacturing processes of the other components are the same as in Embodiment 3. The performance test results are as follows: Slip rate (γ): 2.8%; Single splash volume: 1.5ml; Splash prevention rate (η): 92%; Grip comfort rating: 8.7 points; Independent cleaning completion rate: 80%.

[0043] Comparative Example 1: Ordinary daily mouthwash cup, characterized by single-layer glass material, one-piece large handle (30mm wide), plain appearance, straight mouth design; outer diameter 60mm, height 85mm, weight 150g.

[0044] Comparative Example 2: A commercially available water bottle for the elderly, characterized by a single layer of PP plastic, a double handle design, a diamond-shaped anti-slip texture on the surface, a straight mouth; an outer diameter of 58mm, a height of 82mm, a weight of 110g, and a handle width of 25mm.

[0045] Example 6: The present invention also proposes a comparative test scheme, selecting 30 elderly people aged 60-85, including 15 Parkinson's tremor patients (tremor frequency 4-6Hz) and 15 non-tremor people with decreased grip strength (grip strength ≤15N), 15 men and 15 women, randomly divided into 3 groups, and tested Examples 3-5 and Comparative Examples 1-2 respectively (6 people in each group, cross-testing).

[0046] Testing instruments and equipment: Tremor frequency tester (model: TS-200, accuracy ±0.1Hz); electronic balance (model: FA2004, accuracy ±0.01g, used to measure splash volume); grip strength meter (model: EH101, accuracy ±0.1N); satisfaction rating form (10-point scale, covering 4 dimensions: grip, splash resistance, appearance, and cleanliness).

[0047] Test steps: Slip rate test: Each tester holds the product and performs 100 simulated rinsing actions (tilted at 45°-60°, 30 times / minute), records the number of slips, and calculates the slip rate (γ=number of slips / 100×100%). Splash prevention test: 200ml of room temperature water (25℃) is placed in the cup. The tester completes 10 standard rinsing actions (tilts 60° each time, holds for 2 seconds and then returns to the original position). The amount of water splashed out is measured with an electronic balance and the average value is taken. Splash resistance calculation: Splash resistance η = (200ml - average splash amount) / 200ml × 100%; Comfort test: Fill out the rating form after the test and take the average score of each group; Independent cleaning test: The tester independently disassembles, cleans, and reassembles the product, and records the completion status.

[0048] Test Results Summary Table

[0049] Slip rate comparison: The slip rates of Examples 3-5 of the present invention are all less than 3.5%, which is more than 94.6% lower than Comparative Example 1 (65%) and more than 91.2% lower than Comparative Example 2 (40%). The reason is that the passive locking structure of the ring type 6 replaces the traditional active grip mode, which is suitable for the grip strength decline and low frequency tremor characteristics of the elderly population.

[0050] Splash protection effect comparison: The splash protection rate of the embodiments of the present invention is higher than 98.6%, which is more than 16% higher than Comparative Example 1 (85%) and more than 6.6% higher than Comparative Example 2 (92.5%). The buffer component accurately offsets the low-frequency vibration kinetic energy.

[0051] Ease of cleaning: The modular design of this invention enables an independent cleaning completion rate of over 80%, which is lower than Comparative Example 1 (no disassembly required), but much higher than Comparative Example 2 (70%), thus solving the problem of difficult cleaning of existing age-friendly products.

[0052] In summary, this invention addresses the needs of elderly people (especially those with low-frequency tremors and weakened grip) when using mouthwash cups. It presents an age-friendly, anti-shake mouthwash cup solution that combines stability, safety, scenario adaptability, and emotional support. This solution addresses the problem of existing products relying on active gripping, which cannot handle low-frequency tremors that cause the cup to slip. It achieves a passive, stable locking effect, reducing the risks associated with insufficient grip or hand tremors. It also significantly reduces the risk of water splashing, resulting in slippery surfaces and wet clothing. This is achieved through a combination of cushioning components and a physical splash-proof structure, far exceeding the splash-proof effect of existing products that only offer single anti-slip or basic cushioning.
