Description

Technical Field

[0001] This utility model relates to a breathing training device. Background Technology

[0002] Breathing training, as an effective rehabilitation and exercise method, is widely used in postoperative lung function recovery, adjunctive treatment of respiratory diseases, and athlete physical training. Existing breathing trainers mostly increase inspiratory resistance through adjustable, narrow airflow channels to train respiratory muscles. However, such devices often suffer from the following problems: First, when performing forceful exhalation at high resistance, excessive pressure can easily build up inside the device, leading to instability or even dislodgement from the face, affecting training continuity and user experience; second, resistance adjustment mechanisms often lack precise scale markings, making it difficult for users to accurately reproduce or fine-tune training intensity; furthermore, most products cannot easily adapt to different users' nasal spacing, affecting wearing comfort and airtightness. Therefore, there is an urgent need in this field for a breathing trainer that can balance effective training, safe pressure release, precise adjustment, and comfortable wear. Utility Model Content

[0003] The present invention aims to provide a breathing trainer to solve the technical problems of existing breathing trainers, such as the device easily falling off due to excessive internal pressure during high-resistance training, inaccurate resistance adjustment, and inability to adapt to different nasal distances of users.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A breathing trainer includes a connecting strap and two breathing training components, the connecting strap being used to connect the two breathing training components; Each breathing training component includes a top cover and a bottom shell. The top cover is mounted on the bottom shell and can rotate on the bottom shell. The top cover has a first arc-shaped hole, and the bottom shell has a second arc-shaped hole. When the top cover rotates relative to the bottom shell, the overlap angle between the first arc-shaped hole and the second arc-shaped hole can be adjusted. The top of the bottom shell is also provided with a one-way valve diaphragm. The one-way valve diaphragm allows gas to be discharged from the inside of the breathing trainer to the outside and prevents gas from being inhaled from the outside. The bottom of the bottom shell is the breathing port.

[0005] Furthermore, a filter cotton is provided at the breathing port.

[0006] Furthermore, the top of the bottom shell is a frustum structure, and the top cover has a groove that matches the frustum structure. The top cover is rotatably fitted onto the frustum structure through the groove. The top cover has a through hole at its center, and the frustum structure has a threaded hole at its center. The top cover and the bottom shell are connected by bolts. The bolts pass through the through hole and are threadedly connected to the threaded hole. A wave-shaped washer is provided between the head of the bolt and the top cover.

[0007] Furthermore, the outer periphery of the frustum structure at the top of the bottom shell is evenly distributed with several radial limiting posts.

[0008] Furthermore, the head of the bolt is provided with a through hole; both ends of the connecting strap are provided with plugs, the connecting strap passes through the through holes of the bolt heads of the two breathing training components, and a limiting sleeve is also fitted on the connecting strap.

[0009] Furthermore, the frustum structure at the top of the bottom shell is provided with several angular scale lines.

[0010] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model allows for stepless adjustment of air intake resistance by the overlapping angle of the arc-shaped holes on the top cover and bottom shell, meeting personalized training needs; the unique one-way valve diaphragm design can automatically open to release pressure when the expiratory pressure is too high, effectively preventing the device from falling off and ensuring training safety; (2) The angle scale lines set on the bottom shell make the resistance adjustment based on the data, which makes it easy for users to accurately remember and reproduce their best training state.

[0011] (3) The design of the connecting strap and the limiting sleeve allows users to adjust flexibly according to their own nose spacing, which improves the fit and comfort of wearing and expands the range of applicable people. Attached Figure Description

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] The present invention will be further described in detail below with reference to the embodiments.

[0015] like Figure 1-7 As shown, the breathing trainer of this utility model includes a connecting strap 1 and two breathing training components 2. The two breathing training components 2 have the same structure and are symmetrically connected to both ends of the connecting strap 1.

[0016] Each breathing training component 2 includes a bottom shell 3, a top cover 4, a one-way valve diaphragm 5, and a filter cotton 6.

[0017] The bottom shell 3 is cup-shaped, with a breathing port 7 at its bottom for connecting to the nasal cavity. Preferably, a filter cotton 6 is provided at the breathing port 7 to filter the inhaled air. The top of the bottom shell 3 is constructed as a frustum structure 8, with a threaded hole 9 at its center. The top surface of the frustum structure 8 has a second arc-shaped hole 10 and multiple radial limiting posts 11. Furthermore, the top surface of the frustum structure 8 is also engraved with angle scale lines 12 for indicating the rotation angle.

[0018] The top cover 4 is rotatably mounted on the frustum structure 8 of the bottom shell 3 via a connecting mechanism. Specifically, the bottom of the top cover 4 has a groove 13 that matches the frustum structure 8, allowing the top cover 4 to be stably fitted onto the frustum structure 8 and to rotate around its axis. The top cover 4 has a through hole 14 at its center and a first arc-shaped hole 15 around its circumference.

[0019] The rotating connection mechanism includes a bolt 16 and a corrugated washer 17. The bolt 16 passes through the corrugated washer 17 and the through hole 14 of the top cover 4 in sequence, and is then threadedly connected to the threaded hole 9 of the bottom shell 3. The corrugated washer 17 is elastically pressed between the head of the bolt 16 and the top cover 4, thereby providing appropriate frictional damping for the rotation of the top cover 4, so that it can rotate smoothly and maintain a stable position after adjustment.

[0020] The one-way valve diaphragm 5 is disposed on the top surface of the frustum structure 8 of the bottom shell 3 and is pressed and fixed by the top cover 4. The one-way valve diaphragm 5 and the bottom shell 3 together constitute a one-way valve. Its working principle is as follows: when the user inhales, the internal pressure of the trainer decreases, the one-way valve diaphragm 5 is tightly attached to the valve seat and is in the closed state, forcing all the airflow to enter through the overlapping part of the first arc-shaped hole 15 and the second arc-shaped hole 10, thereby generating breathing resistance; when the user exhales, when the internal air pressure rises to a certain value, the one-way valve diaphragm 5 is pushed open, forming a pressure relief channel, allowing the gas to be discharged quickly, effectively reducing the internal pressure and preventing the trainer from falling off due to excessive pressure.

[0021] The connecting strap 1 is used to connect two breathing training components 2. Specifically, the head of the bolt 16 has a through hole 18, preferably an oblong hole. Each end of the connecting strap 1 has a plug 19. The connecting strap 1 passes through the through holes 18 in the heads of the two bolts 16 and is limited by the plugs 19 at both ends. A limiting sleeve 20 is also fitted onto the connecting strap 1. By sliding the limiting sleeve 20, the effective length between the two ends of the connecting strap 1 can be adjusted to accommodate the nasal distance of different users.

[0022] In use, the user first slides the limiting sleeve 20 to adjust the length of the connecting strap 1, ensuring that the breathing ports 7 of the two breathing training components 2 are comfortably aligned with the nostrils. Then, the top cover 4 is rotated according to training needs. By observing the degree of overlap between the first arc-shaped hole 15 and the second arc-shaped hole 10, and referring to the angle scale line 12, the opening size of the air intake channel can be precisely set. The smaller the overlap angle, the greater the air intake resistance and the higher the training intensity; conversely, the smaller the resistance and the lower the intensity.

[0023] During inhalation, the user needs to inhale forcefully to overcome the resistance of the airflow channel, thereby training the respiratory muscles. During exhalation, in addition to some airflow being expelled from the original channel, when internal pressure accumulates, the one-way valve diaphragm 5 will open to release pressure, ensuring safe use and preventing the device from falling off.

[0024] It should be noted that, in this document, terms such as “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
