Description

Technical Field

[0001] The utility model belongs to the field of respiratory training instruments, and particularly relates to an adjustable breathing valve and a respiratory muscle training mask. Background Technique

[0002] Respiratory muscles include the diaphragm, intercostal muscles, pectoralis major, pectoralis minor, etc., which are responsible for realizing the ventilation function of the lungs. Under normal circumstances, respiratory muscles can easily complete the breathing task. Athletes, especially those engaged in endurance sports such as long-distance running, swimming, and cycling athletes, need strong respiratory muscles to support their oxygen demand during high-intensity training and competitions. The strength and endurance of respiratory muscles directly affect the breathing efficiency and athletic performance of athletes. Many athletes will conduct high-altitude training to improve their athletic ability in a low-oxygen environment. In a high-altitude environment, due to the thin air, respiratory muscles need to work harder to maintain sufficient oxygen supply. Therefore, the adaptability and training of respiratory muscles are particularly important for high-altitude athletes. In addition, in special working environments such as divers and high-altitude workers, the training of respiratory muscles is equally crucial. Divers need to resist water pressure underwater, while high-altitude workers need to resist the low-oxygen environment at high altitudes. These environments pose additional challenges to respiratory muscles, so the strength and endurance of respiratory muscles are crucial for their work performance and safety.

[0003] In traditional respiratory muscle training devices, the respiratory training device disclosed in the patent document with the literature number CN220459855U, "A Multifunctional Respiratory Training Device", is for patients with respiratory tract infections or asthma. It provides a training device that integrates respiratory training, oxygen therapy, and nebulization therapy, and can adjust the respiratory resistance according to the specific conditions and training needs of the patients. However, this device is less targeted at athletes, divers, and high-altitude workers, has a complex operation, requires certain training for patients or medical staff to be effectively used, and needs to be held by hand during use, restricting the participation methods of training. The patent document with the literature number CN219376011U, "A Respiratory Exerciser", provides a training device that separates exhalation and inhalation for users. It is fixed to the head in the form of a strap, effectively liberating the user's hands and greatly improving the training abundance. However, this utility model strictly restricts the respiratory mode and can only be trained in the form of nasal inhalation and oral exhalation, which will undoubtedly affect the training effect because in the actual operation process, in most cases, both the mouth and nose are used for breathing, and the adjustment of the control component has a certain operational complexity. The cleaning and maintenance of the device may be more cumbersome, and the use cost is relatively high. The respiratory mask disclosed in the patent document with the literature number CN210933640U, "A Respiratory Mask for Chronic Obstructive Pulmonary Disease Functional Exercise", can not only be fixed to the head but also achieve separate training for the inhalation and exhalation processes. However, this device has a complex structure, is not easy to disassemble, is not easy to clean, is prone to dirt accumulation, and the complex structure is accompanied by an increase in cost, having certain limitations.

[0034] Embodiment 1

[0035] As Figures 1 - 3As shown in the figure, this embodiment provides an adjustable breathing valve, which includes a valve housing 11, a valve plate 12, and an annular switching member 13. The valve plate 12 is a flexible diaphragm, and the valve plate 12 is arranged inside the valve housing 11. An air inlet hole 111 is arranged at one end of the valve housing 11, and an air outlet hole 112 is arranged at the other end of the valve housing 11. The valve plate 12 is located between the air inlet hole 111 and the air outlet hole 112. When the pressure difference between the air inlet hole 111 and the air outlet hole 112 is positive, the valve plate 12 is in an open state. When the pressure difference between the air inlet hole 111 and the air outlet hole 112 is negative, the valve plate 12 is in a closed state. The side wall of the switching member 13 is provided with a plurality of ventilation holes 131 of different sizes and annularly spaced apart (the sizes of the plurality of ventilation holes are different. Preferably, the ventilation holes are all circular holes. At this time, the diameters of the plurality of ventilation holes are different. Of course, the air inlet can also adopt a circular hole). The air inlet hole 111 is arranged on the side wall of the corresponding end of the valve housing 11, and the switching member 13 is rotatably sleeved on the valve housing 11, and the air inlet hole 111 is located within the ring of the switching member 13. Rotate the switching member 13 until any one of the ventilation holes 131 is aligned with the air inlet hole 111 to adjust the size of the air flow rate; by providing a rotatable switching member on the valve housing, and the air inlet hole on the valve housing is located within the ring of the switching member, and the switching member is provided with a plurality of ventilation holes that are annularly spaced apart and of different sizes, so that when the switching member is rotated until any one of the ventilation holes on it is aligned with the air inlet hole, the air flow rate of the entire adjustable breathing valve can be adjusted. When the switching member is rotated to block the air inlet hole, at this time the air inlet hole is in a closed state, and the air flow cannot pass through the adjustable breathing valve at this time.

[0036] See details Figure 1 and Figure 2 As shown in the figure, in the above technical solution, the plurality of ventilation holes 131 are annularly spaced apart in sequence on the valve housing 11 in the order of the hole diameters. In this way, when the switching member rotates, the switching member can be rotated flexibly and conveniently according to the needs of the air flow rate.

[0037] In the above technical solution, the diameter of the ventilation hole 131 with the largest hole diameter is the same as the diameter of the air inlet hole 111. Its structure is simple and the adjustment is convenient.

[0038] In the above technical solution, the distance between any two adjacent ventilation holes 131 is greater than the diameter of the air inlet hole 111; in this way, it can be avoided that the air inlet hole communicates with two ventilation holes at the same time.

[0039] Embodiment 2

[0040] Such as Figure 4As shown in the figure, this embodiment provides a respiratory muscle training mask, which includes a mask body 2 and a wearing piece 3. The wearing piece 3 is arranged on the mask body 2, and the mask body 2 is worn through the wearing piece 3. Two breathing valves 1 are arranged on the mask body 2, and the breathing valves 1 are adjustable breathing valves as described in Embodiment 1. The two breathing valves 1 are an inhalation valve 1a and an exhalation valve 1b respectively. Its structure is simple, and the air flow rate of the two breathing valves can be flexibly adjusted for respiratory muscle training. Of course, the air flow rate of any one breathing valve can also be adjusted to zero for separate inhalation training or exhalation training. In this embodiment, the installation directions of the two breathing valves on the mask body 2 are different, and the two breathing valves are spaced left and right on the mask body. However, the intake end of one breathing valve is located outside the mask body (i.e., the side away from the nose, and this breathing valve is the inhalation valve, which can only inhale external air into the inner side of the mask body), while the intake end of the other breathing valve is located inside the mask body (i.e., the side close to the nose, and this breathing valve is the exhalation valve, which can only discharge the gas exhaled by people to the outside).

[0041] In the above technical solution, the mask body 2 is a non-breathable material piece (which can be a plastic material piece, and its main function is to fit with the human face and wrap the mouth and nose of people inside). In this way, the air flow will only pass in and out through the breathing valves, which can improve the controllability of the respiratory muscle training mask.

[0042] At present, the fabric of existing masks is breathable (such as the mask disclosed in the patent document with the document number CN220174536U "A New Type of Protective Mask"), and only one breathing valve is provided (and this breathing valve is equivalent to an exhalation valve, that is, when inhaling, the air is filtered by the mask, and when exhaling, it directly passes through the breathing valve for unobstructed discharge to the outside. In contrast to the prior art, this embodiment is not for filtering air, but for respiratory resistance training. Therefore, in this embodiment, the structure of the breathing valve is improved, two breathing valves are provided, and at the same time, the fabric of the mask body is set to be non-breathable, so that the air entering and leaving the mask body can only flow through the two breathing valves).

[0043] Such as Figure 4 and Figure 5 As shown in the figure, the above technical solution further includes a signal indicator 4 arranged outside the mask body 2. The signal indicator 4 has an indicating member 41, and the signal indicator 4 controls the operating frequency of the indicating member 41. In this way, the signal indicator can periodically operate through the indicating member to guide the training personnel to adjust the breathing frequency.

[0044] Such as Figure 5 and Figure 6As shown in the figure, the signal indicator 4 in the above technical solution further includes a housing 42, a power switch 43, a controller 44, and a power supply unit 45. The controller 44 and the power supply unit 45 are both arranged inside the housing 42. The housing 42 is installed on the outer side of the mask body 2, and the indicating member 41 and the power switch 43 are both arranged on the housing 42. The power supply unit 45 and the indicating member 41 are both electrically connected to the controller 44. The power switch 43 is arranged on the circuit where the power supply unit 45 is electrically connected to the controller 44. Its structure is simple, and the indicating effect is good. At the same time, the operating frequency of the indicating member can be adjusted (in this embodiment, the controller can adopt a relatively small single-chip microcomputer, and the adjustment knob of the single-chip microcomputer is exposed outside the housing 42, specifically, it can be an Arduino series single-chip microcomputer).

[0045] In the above technical solution, the power supply unit 45 is a button battery box; its volume is small.

[0046] In the above technical solution, the indicating member 41 is a light-emitting diode (for the flashing of the lamp tube), a vibration motor (for periodic vibration), or a buzzer (for periodically emitting a beeping sound); its structure is simple, and the signal emitted has a good reception effect by the training personnel.

[0047] The feature of this embodiment is that by setting two breathing valves with adjustable air passing flow rate (that is, adjustable air passing resistance) and installed in opposite directions on the mask body to adjust the resistance load of breathing, by rotating the switching members of the two breathing valves and adjusting the air passing flow rates of the two respectively, exhalation training, inhalation training, and breathing training can be realized. Among them, the mask body is worn on the head through a wearing member, which can free the hands, enrich the training content, improve the diversity of training. At the same time, the respiratory muscle training mask has a simple structure, strong durability, is easy to disassemble, easy to clean, has no complex structure, simple operation, low production and operation costs, and high cost performance; and setting a signal indicator can conduct targeted training on the breathing rhythm by the indicating member emitting periodic signals (such as performing a breathing action when the indicating member emits a signal once, or the training personnel alternately performing inhalation and exhalation actions for two adjacent signals emitted by the indicating member).

[0048] Training mode 1 (exhalation training):

[0049] At this time, after the training personnel wear the respiratory muscle training mask, adjust the air passing flow rate of the exhalation valve to zero, and adjust the air passing flow rate of the inhalation valve to the maximum. At this time, the training personnel have no resistance when inhaling, and when exhaling (due to the obstruction of the exhaled gas), the exhalation muscle group conducts resistance training at this time.

[0050] Training mode 2 (inhalation training):

[0051] At this time, after the trainer wears the respiratory muscle training mask, the air passing flow rate of the inhalation valve is adjusted to zero, while the air passing flow rate of the exhalation valve is adjusted to the maximum. At this time, there is no resistance when the trainer exhales, while when inhaling (due to the obstruction of inhaled air), the inspiratory muscle group undergoes resistance training (when training, it is not necessary for the trainer to endure forcefully. If they feel suffocated, they can immediately remove the mask body by themselves).

[0052] Training mode three (respiratory training):

[0053] At this time, after the trainer wears the respiratory muscle training mask, the air passing flow rates of the two respiratory valves are adjusted according to needs (neither is in the state of zero air passing flow rate), and at this time, the trainer performs normal breathing actions.

[0054] In the above three training modes, a periodic signal can be emitted by the signal indicator to guide the trainer to breathe.

[0055] As mentioned above, it is only the preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention; any ordinary technician in this industry can smoothly implement the present invention as shown in the accompanying drawings of the specification and as described above; however, any slight changes, modifications, and equivalent variations made by those skilled in this profession without departing from the technical solution of the present invention and by using the technical content disclosed above are all equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications, and variations made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
