Description

Technical Field

[0001] This utility model relates to a physical exercise device, and more particularly to an air-blowing training device, which allows users to exercise their abdominal muscles and lung capacity by blowing air. Background Technology

[0002] In the field of lung training, improving vital capacity and respiratory muscle strength is crucial for enhancing respiratory function and improving quality of life. However, existing respiratory training devices have many limitations. For example, some devices can only train expiratory muscle strength and cannot effectively train inspiratory muscle strength; others, while allowing adjustment of training difficulty, lack the function of quantitatively assessing the user's respiratory pressure, making it difficult to meet personalized training needs.

[0003] Both Chinese utility model patent CN220448020U and US invention patent US10722748B1 propose a respiratory pressure load-type resistance training device, which utilizes the weight of breathing weights and airflow resistance to regulate the user's breathing. This design not only strengthens lung muscle strength but also significantly improves lung control and capacity. The training device allows different users, or users in different physical states, to adjust the load value generated by their breathing by adding or removing weights within the container. However, the force gradient is adjusted in units of weight, making it difficult to make large-to-small step adjustments. Utility Model Content

[0034] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0035] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0036] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. 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.

[0037] This embodiment provides an air-blowing training device, the structure of which is as follows: Figure 1-6 As shown, the device includes an air cylinder 1, an air tube 2, and an exhalation mask 3. The upper end of the air cylinder 1 has an air inlet, and the exhalation mask 3 is connected to the air inlet via the air tube 2. The air cylinder 1 contains an elastic element 5 and a movable block 6. The contour of the movable block 6 matches the inner hole of the air cylinder 1, and there is a clearance between them. The movable block 6 is positioned above the elastic element 5. When the exhaled airflow from the person in the exhalation mask 3 enters the air inlet of the air cylinder 1 through the air tube 2, it creates a force that pushes the movable block 6 to move and compress the elastic element 5. In this embodiment, the elastic element 5 is a cylindrical compression spring.

[0038] When a user uses this air-blowing trainer, regardless of the blowing force, the exhaled airflow from the body in the exhalation mask 3, after entering the air inlet of the air cylinder 1 through the air tube 2, will create a force that pushes the movable block 6 to move and compresses the elastic element 5. This design allows even people with weak respiratory function to push the movable block 6 to produce a certain displacement with a relatively small blowing force, thus achieving a training effect. Simultaneously, as training progresses, the user can gradually increase the blowing force, pushing the movable block 6 to move a greater distance and compressing the elastic element 5 to a greater extent, achieving a gradual training effect.

[0039] like Figure 1 , 4 As shown in Figure 7, a scale section 7 is provided on one side of the movable block 6, and a viewing window 8 is provided on the peripheral wall of the air cylinder 1. The scale of the scale section 7 is opposite to that of the viewing window 8. The scale in the viewing window 8 changes as the movable block 6 moves down, intuitively displaying the user's blowing force and effect, providing real-time training feedback to the user. This allows the user to adjust the blowing force according to the scale changes, enabling scientific breathing training and helping to improve the motivation and effectiveness of training. This design not only provides real-time training feedback to the user but also facilitates medical staff or rehabilitation instructors to assess the patient's respiratory function recovery based on scale changes, thereby achieving precise training monitoring.

[0040] Preferably, such as Figure 2 , 6 As shown in Figures 7 and 8, a vertical, elongated scale bar 9 is provided on one side of the movable block 6, with the scale portion 7 located on the outer surface of the scale bar 9. This elongated scale bar 9 design makes the scale display clearer and more intuitive. It also reduces the need for a large transparent window, providing better obscuring of the air pump's interior. The scale bar 9 extends vertically, consistent with the movement direction of the movable block 6, eliminating the need for frequent adjustments to the viewing angle when observing the scale, thus improving convenience and accuracy. Furthermore, the vertical scale bar 9 more intuitively reflects the displacement changes of the movable block 6, further enhancing the visualization of training effects. Through the clear scale display, users can more accurately understand the changes in their blowing force with each breath, clearly noticing even small improvements or significant enhancements, allowing for more targeted training and better adapting to the training needs of individuals with different respiratory functions, achieving scientific breathing training.

[0041] Furthermore, the scale bar 9 extends vertically downwards from the lower end of the movable block 6, covering the entire movement range of the movable block 6. This design allows the scale bar 9 to cover the entire displacement range of the movable block 6, ensuring accurate readings of the scale values ​​at any position. Simultaneously, the vertically extending scale bar 9 is perfectly aligned with the movement direction of the movable block 6, further improving the accuracy and intuitiveness of the scale display and providing users with more precise training feedback.

[0042] like Figure 7, 8 As shown, a longitudinal guide structure is provided between the peripheral sidewall of the movable block 6 and the inner wall of the air cylinder 1. This guide structure includes matching longitudinal grooves 16 and longitudinal ribs 17. In this embodiment, the peripheral sidewall of the movable block 6 has a longitudinal groove 16, and the inner wall of the air cylinder 1 has a longitudinal rib 17. The longitudinal groove 16 and the longitudinal rib 17 fit together. This guide structure ensures that the movable block 6 moves smoothly and steadily up and down within the air cylinder 1, avoiding any impact on the training effect due to the wobbling of the movable block 6. This guide structure not only improves the service life of the trainer but also enhances the stability and accuracy of the training process. Regardless of the user's blowing force, the movable block 6 can move stably within the air cylinder 1, ensuring the smooth progress of the training process. Stable movement of the movable block 6 provides the user with more accurate training feedback, helping the user better understand their respiratory function status and gradually adjust the blowing force according to the training level to achieve scientific breathing training.

[0043] like Figure 7 As shown, the upper surface of the movable block 6 is provided with an air-receiving groove 18, which is coaxial with the air inlet. This allows the exhaled airflow from the human body in the exhalation mask 3 to accurately act on the air-receiving groove 18, concentrating the force of the airflow and more effectively propelling the movable block 6 to move. The design of the air-receiving groove 18 not only improves the sensitivity of the trainer but also ensures efficient utilization of the airflow, further enhancing the training effect. Preferably, the center of the air-receiving groove 18 is provided with a cross-shaped protrusion 4 to reinforce the structure.

[0044] like Figure 6 As shown, a perforated window 20 is provided on one side of the air cylinder 1, and a viewing window 8 is provided at the perforated window 20.

[0045] like Figure 1 , 4 As shown in Figure 6, the top of the air pump 1 is equipped with a cap 14, and the air inlet is located at the center of the cap 14. The cap 14 is screwed onto the upper end of the air pump 1, and a connecting tube 15 is rotatably provided at the inlet of the cap 14. This rotatable connecting tube 15 makes the connection between the exhalation mask 3 and the air pump 1 more flexible, allowing users to adjust the angle of the exhalation mask 3 according to their usage habits, improving comfort and convenience. The screw-on cap 14 ensures a secure connection, and at the same time, the screw-on cap 14 facilitates cleaning of the air pump, better meeting hygiene requirements.

[0046] like Figure 1 , 2As shown in Figures 4 and 6, the lower end of the air cylinder 1 is provided with a support base 10, and a counterweight 11 is provided inside the support base 10. The counterweight 11 can significantly increase the overall stability of the trainer and prevent it from tipping over due to external forces during use. This is especially suitable for rehabilitation training scenarios, ensuring that users can operate the trainer safely and stably during training, and avoiding the impact on training effects or accidental injuries caused by equipment shaking.

[0047] Furthermore, as shown in the figure, the bottom surface of the support base 10 is equipped with an anti-slip pad or suction cup. The suction cup can adhere tightly to the placement surface, and the anti-slip pad can increase friction, further enhancing the adhesion between the trainer and the tabletop. Whether on a smooth tabletop or other flat surfaces, this ensures that the trainer remains stable during use, preventing slippage due to insufficient surface friction. This design not only improves the applicability of the trainer but also provides users with a safer and more reliable user experience.

[0048] like Figure 1 , 2 As shown in Figures 4, 6, and 8, the bottom of the air cylinder 1 is open, and its lower section has a threaded portion 13. The support base 10 is screwed onto the air cylinder 1 through the threaded portion 13. The support base 10 includes a partition 110, which seals the bottom of the air cylinder 1 to form a closed cavity. This screw-on connection method is not only convenient for installation and disassembly, but also allows users to easily replace or clean the support base 10 as needed. In addition, the robustness of the threaded connection ensures a tight fit between the support base 10 and the air cylinder 1, further enhancing the overall stability of the trainer.

[0049] like Figure 2 , 6 As shown, the support base 10 includes an upper support seat 101 and a lower support wall 102, which are detachably connected by snap-fit ​​or by fasteners. With this type of base, users can choose whether to install the support base 10 or replace it with a counterweight 11 of different weights according to different training needs or usage scenarios to adapt to the training needs of people with different respiratory functions.

[0050] like Figure 1-6 As shown, the cross-section of the support base 10 gradually expands from top to bottom, thereby improving the support performance. Anti-slip pads or suction cups can be provided at the bottom of the lower support wall 102, or the bottom of the lower support wall 102 can be provided with anti-slip texture.

[0051] like Figure 2 As shown, the partition 110 is provided on the upper support base 101, and the upper side of the partition 110 is provided with a positioning post 19. When the support base 10 is screwed into the air cylinder 1, the positioning post 19 extends into the interior and becomes a fixed spring.

[0052] This invention provides an air-blowing training device. Specific examples are used to illustrate the principle and implementation of this invention. The descriptions of the embodiments are merely for the purpose of helping to understand this invention and its core ideas. It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this invention.
