Description

Technical Field

[0001] This utility model relates to the field of decompression toy technology, and more specifically, to a fingertip press decompression toy. Background Technology

[0002] With the fast pace of modern life and significantly increased work and study pressures, people urgently need a portable, safe, and low-cost tool for immediate emotional release. Various "stress-relieving toys" have emerged on the market, such as elastic balls, bubble boards, and magnetic sliders, most of which rely on the elastic deformation of materials or repeated magnetic force to reset. However, these products generally suffer from the following shortcomings: 1. Rapid decay of reset force and short lifespan; 2. Limited tactile feedback, unable to provide continuous and stable damping feedback; 3. Exposed structure, prone to pinching fingers or accumulating dirt, resulting in poor hygiene; 4. High noise level, unsuitable for quiet environments such as offices and libraries.

[0003] Based on the above drawbacks, this application proposes a new structure that applies the principle of air pressure damping to handheld decompression toys, which can simultaneously solve the problems of short lifespan, poor feel, and high noise in existing decompression toys. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a decompression toy with a long service life, high-frequency pressing operation, good feel and low noise.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fingertip press-to-decompress toy, comprising a cylindrical body, the inner cavity of which forms a piston chamber, and a limiting cover at the bottom of the cylindrical body to seal the bottom end of the piston chamber. The limiting cover is threadedly engaged with the cylindrical body. A pressing rod is inserted into the cylindrical body, and the pressing rod is inserted into the piston chamber with a clearance fit and can slide up and down axially. When the pressing rod slides down, the air in the piston chamber is allowed to be compressed and slowly discharged. When the pressing rod is released, the external air is allowed to flow back, so that the pressing rod automatically rises under the action of the internal air pressure and the external atmospheric pressure difference.

[0006] The present invention is further configured such that a push-button switch is provided on the inner surface of the limiting cover facing the bottom area of ​​the cylinder.

[0007] The present invention is further configured such that: the first end of the pressing rod is a pressing end with concave and convex annular texture, and the tail end is a pressing end with at least two concave annular grooves along the circumference of the pressing end.

[0008] The present invention is further configured such that the gap width between the outer wall of the pressing rod and the outer wall of the piston cavity on the cylinder is 3μm-4μm.

[0009] The present invention is further configured such that the outer surface of the cylinder and the outer surface of the limiting cover are both provided with concave textures.

[0010] By adopting the above technical solutions, the product offers the following advantages: 1. Long service life: "Air pressure micro-gap damping" replaces traditional elastomers or magnetic reset structures, leaving only a 3-4 μm annular micro-gap between the pressing rod and the cylinder. This gap provides controllable air damping while avoiding solid friction, spring fatigue, magnet demagnetization, and material creep. 2. Dual benefits of anti-slip appearance and fingertip massage: The outer surface of the cylinder and the outer surface of the limiting cover are designed with concave textures, increasing grip friction and stimulating acupoints on the fingertips during handling. The annular textured surface at the top of the pressing rod massages the fingertips while pressing, promoting peripheral blood circulation and achieving a dual experience of "stress relief + micro-fitness." 3. Low noise: Suitable for high-frequency use in quiet places such as offices, classrooms, subways, and libraries without disturbing others. 4. Continuously stable damping feel, satisfying those who need to release pressure. 5. High manufacturing precision: The precise fit between the pressing rod and the sleeve allows for both sliding contact and optimal reduction of the gap. Attached Figure Description

[0013] Reference Figures 1 to 6 The embodiments of this utility model will be further described below.

[0014] A fingertip-pressing decompression toy includes a cylindrical body 1, the inner cavity of which forms a piston chamber 2. A limiting cover 3 is provided at the bottom of the cylindrical body 1 to seal the bottom end of the piston chamber 2. The limiting cover 3 is threadedly engaged with the cylindrical body 1. A pressing rod 4 is inserted into the cylindrical body 1. The pressing rod 4 is inserted into the piston chamber 2 with a clearance fit and can slide up and down axially. When the pressing rod 4 slides down, it allows the air in the piston chamber 2 to be compressed and slowly discharged. When the pressing rod 4 is released, it allows the external air to flow back, so that the pressing rod 4 automatically rises under the action of the internal air pressure and the external atmospheric pressure difference.

[0015] A push-button switch 5 is provided on the inner surface of the limiting cover 3 facing the bottom area of ​​the cylinder 1. The pressing rod 4 has a pressing end with concave and convex annular textures at its front end and a pressing end with at least two concave annular grooves 6 along its circumference. The gap width between the outer wall of the pressing rod 4 and the outer wall of the piston cavity 2 on the cylinder 1 is 3μm-4μm. Both the outer surface of the cylinder 1 and the outer surface of the limiting cover 3 have concave textures.

[0016] Example 1: Refer to the attached instruction manual Figure 1 In this state, the bottom end of the pressing rod 4 directly abuts against the button switch 5 of the limit cover 3, and its end portion is located outside the piston chamber 2. By continuously pressing its end, in conjunction with the button switch 5, a continuous pressing sensation is achieved, which helps to release pressure. At the same time, the texture on the end face of the pressing rod 4 can improve the feel, making the fingertips feel more comfortable when pressing.

[0017] Example 2: Refer to the attached instruction manual Figure 2 In this state, most of the pressing rod 4 is located outside the piston chamber 2. By continuously pressing the pressing rod 4, the pressing rod 4 will form a pressing-recovery state through the airflow damping in the piston chamber 2, thus achieving the purpose of decompression.

[0018] Example 3: An annular groove 6 is provided at the tail end of the pressing rod 4. When the pressing rod 4 is disengaged from the piston chamber 2, a sound is generated, which can be used as the decompression content.

[0019] Example 4: The pressing rod 4 is placed upside down on a flat surface. Then, the cylinder 1 is fitted onto the tail end of the pressing rod 4 through the piston chamber 2. Rotating the cylinder 1 causes it to rotate along the outer surface of the pressing rod 4, continuously engaging the cylinder 1 with the pressing rod 4. The rotation of the cylinder 1 serves as the decompression mechanism.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
