Abstract
Description
Technical Field
[0001] This utility model belongs to the field of human respiratory function training, and in particular relates to a respiratory safety valve and a respiratory function training mask. Background Technology
[0002] For healthy individuals, strong respiratory muscles are required to inhale and exhale during physical activity. Currently, common methods for training respiratory function mainly involve altering the oxygen concentration in the environment, such as high-altitude training, to further stimulate the respiratory system. However, this has strict requirements for the environment and venue, and the training cost is high. Of course, there are also methods that use respiratory function training masks to train respiratory function. In this case, the respiratory function training mask mainly provides inspiratory and expiratory resistance, requiring the user to extend and contract the respiratory muscles to a greater extent during breathing, thereby improving respiratory function. However, current breathing masks are equipped with inspiratory and expiratory one-way valves. The inspiratory one-way valve is very likely to become blocked during training in complex environments. If the inspiratory valve becomes blocked when the user is performing special activities or sports training (such as rock climbing), the user may not be able to free their hands to remove the mask, which may lead to suffocation. Utility Model Content
[0003] In view of the suffocation hazard of the aforementioned respiratory function training mask, one of the purposes of this utility model is to provide a breathing safety valve with a simple structure and good safety.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A breathing safety valve includes a valve tube, a safety membrane, and two filter elements. The valve tube is arranged in a front-to-back direction, and the two filter elements are spaced apart in the front-to-back direction inside the valve tube. The safety membrane is disposed inside the valve tube and located between the two filter elements. The safety membrane is in contact with the filter element located in front. When air is blown forward from the rear end of the valve tube, the safety membrane is in contact with the filter element located in front and blocks the airflow inside the valve tube to prevent the airflow from flowing forward. When air is drawn backward from the rear end of the valve tube, the safety membrane expands backward into a spherical shape until it ruptures, thereby opening the valve tube.
[0005] The beneficial effects of the above technical solution are as follows: when the rear end of the breathing safety valve blows air forward, the safety membrane will not rupture due to the support of the filter element located in front, and the valve tube can be kept in a blocked state. When the rear end of the breathing safety valve inhales backward, if the inhalation intensity is large enough, the safety membrane will be squeezed and ruptured due to the pressure difference between the two ends, so that the interior of the breathing safety valve can be in a state of front-to-back connection.
[0006] The safety film described in the above technical solution has an easy-tear line.
[0007] The beneficial effect of the above technical solution is that the strength of the area with the tear line on the safety film is relatively low, making the rear end of the breathing safety valve more likely to break when inhaling.
[0008] The safety film described in the above technical solution is a PET film.
[0009] The beneficial effects of the above technical solution are that it makes the preparation simple and has good tensile properties.
[0010] The above technical solution includes multiple easy-tear lines, which are arranged radially on the safety film and distributed in a crisscross pattern.
[0011] The beneficial effect of the above technical solution is that it ensures that the safety film will not shatter into fragments after it breaks.
[0012] The filter element mentioned in the above technical solution is a filter screen.
[0013] The beneficial effects of the above technical solution are that it provides good support performance and at the same time prevents fragments of the safety membrane from overflowing out of the valve tube with the airflow.
[0014] The above technical solution also includes a vent cap, which is installed at the front end of the valve tube and has multiple vent holes that communicate with the interior of the valve tube.
[0015] The beneficial effect of the above technical solution is that the vent cap can protect the front end of the valve tube from rain.
[0016] In the above technical solution, the vent cap is groove-shaped, the front end of the valve tube extends into the vent cap, and the groove end of the vent cap is turned inward to fit with the front end of the valve tube. The vent hole is provided on the bottom wall of the groove of the vent cap.
[0017] The advantages of the above technical solution are that it has a simple structure and good rainproof effect.
[0018] The breathable cap described in the above technical solution has a layer of breathable cotton pad inside.
[0019] The beneficial effect of the above technical solution is that the breathable cotton pad can further filter the airflow entering the valve tube to prevent the inhalation of droplets, pollen, etc.
[0020] The second objective of this invention is to provide a respiratory function training mask with a simple structure and good safety.
[0021] To achieve the above objectives, another technical solution of this utility model is as follows: a respiratory function training mask, comprising a mask body and a respiratory safety valve as described above, wherein the respiratory safety valve is disposed on the front side of the mask body, and the rear end of the valve tube is connected to the mask body and penetrates the mask body.
[0022] The beneficial effect of the above technical solution is that when the user wears the respiratory function training mask for respiratory function training, if the inhalation resistance is too high, the user can take a deep breath, which will cause the safety membrane to rupture, allowing air to enter and exit the mask body through the breathing safety valve.
[0023] The above technical solution also includes an inhalation one-way valve, an exhalation one-way valve, and a filter layer. The inhalation one-way valve and the exhalation one-way valve are both located at the front end of the mask body, and the filter layer is located at the inlet or outlet end of the inhalation one-way valve.
[0024] The beneficial effects of the above technical solution are as follows: when a user uses the respiratory function training mask for respiratory function training, under normal circumstances, the airflow is exchanged with the outside world through the inhalation one-way valve and the expiration one-way valve, while the filter layer can also provide inhalation resistance to improve the user's inhalation resistance effect, thereby achieving the training of respiratory muscles.

[0034] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will be more clearly described in light of the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.
[0035] Example 1
[0036] like Figure 1 - Figure 3 As shown, this embodiment provides a breathing safety valve, including a valve tube 1, a safety membrane 2, and two filter elements 3. The valve tube 1 is arranged in a front-to-back direction, and the two filter elements 3 are spaced apart in the front-to-back direction inside the valve tube 1. The safety membrane 2 is disposed inside the valve tube 1 and located between the two filter elements 3. The safety membrane 2 is in contact with the filter element 3 located in front. When air is blown forward from the rear end of the valve tube 1, the safety membrane 2 and the filter element 3 located in front are in contact with each other, thus isolating the interior of the valve tube 1 to prevent air from entering. As the airflow moves forward, when the rear end of the valve tube 1 draws air backward, the safety membrane 2 expands backward into a spherical shape until it ruptures, thus opening the passage within the valve tube 1. When the rear end of the breathing safety valve blows air forward, the safety membrane is supported by the filter element located in front, preventing it from rupturing and keeping the inside of the valve tube sealed. When the rear end of the breathing safety valve draws air backward, if the suction intensity is sufficiently high, the safety membrane will rupture due to the pressure difference between the two ends, thus allowing the interior of the breathing safety valve to be in a state of unobstructed flow.
[0037] in, Figure 2 and Figure 3 The dashed arrows in the diagram indicate the direction of airflow during inhalation or exhalation.
[0038] like Figure 4As shown, the safety film 2 in the above technical solution is provided with easy-tear lines 21. This makes the strength of the safety film relatively low at the location of the easy-tear lines, thus making the rear end of the breathing safety valve easier to break during inhalation. The safety film 2 is a PET film, which makes its preparation simple and provides good tensile strength. Multiple easy-tear lines 21 are provided, and these lines are radially arranged and intersecting each other on the safety film 2, so that the safety film will not form fragments after breaking. The edge of the safety film is sealed to the valve tube. Preferably, two easy-tear lines can be provided on the safety film, intersecting in an "X" shape.
[0039] like Figure 5 As shown, the filter element 3 in the above technical solution is a filter screen, which provides good support and prevents fragments of the safety membrane from overflowing out of the valve tube with the airflow. The edge of the filter element is connected to the inner wall of the valve tube. Besides its filtering function, the filter element located at the front plays a crucial supporting role, especially during exhalation, ensuring the safety membrane adheres to the front filter element to prevent breakage. In this embodiment, the filter screen can be a 60-100 mesh steel wire mesh, preferably an 80 mesh steel wire mesh.
[0040] like Figure 6 As shown, the above technical solution also includes a breathable cap 4, which is installed at the front end of the valve tube 1. The breathable cap 4 has multiple breathable holes 41 that communicate with the interior of the valve tube 1, so that the breathable cap can protect the front end of the valve tube from rain. Preferably, the breathable cap 4 is groove-shaped, with the front end of the valve tube 1 extending into the breathable cap 4, and the groove end of the breathable cap 4 is turned inward to fit with the front end of the valve tube 1. The breathable holes 41 are located on the bottom wall of the groove of the breathable cap 4. Its structure is simple and has a good rainproof effect. More preferably, a breathable cotton pad 42 is provided inside the breathable cap 4, so that the breathable cotton pad can further filter the airflow entering the valve tube to prevent the inhalation of droplets, pollen, etc.
[0041] Preferably, in this embodiment, the breathable cotton pad 42 can be directly installed at the front end of the valve tube and located inside the breathable cap. In this embodiment, the edge of the breathable cap extends outward, so that even if a small amount of rainwater enters the breathable cap, it will temporarily remain inside the breathable cap and will not wet the breathable cotton pad. Furthermore, it is even more preferred that a drain hole can be provided at the lower edge of the breathable cap (to allow the water inside the breathable cap to drain out). The breathable cotton pad can be directly made of 2-3 layers of gauze.
[0042] Example 2
[0043] like Figure 7As shown, this embodiment provides a respiratory function training mask, including a mask body 200 and a respiratory safety valve 100 as described in Embodiment 1. The respiratory safety valve 100 is located on the front side of the mask body 200, and the rear end of the valve tube 1 is connected to the mask body 200 and communicates with the inside of the mask body 200. In this way, when the user wears the respiratory function training mask for respiratory function training, if the inhalation resistance is too high (when the user is at risk of suffocation), the user can take a deep breath, thereby causing the safety membrane to rupture, so that air can enter and exit the mask body through the respiratory safety valve.
[0044] like Figure 7 and Figure 8 As shown, the above technical solution also includes an inspiratory one-way valve 300, an expiratory one-way valve 400, and a filter layer 500. Both the inspiratory one-way valve 300 and the expiratory one-way valve 400 are located at the front end of the mask body 200. The filter layer 500 is located at the inlet or outlet end of the inspiratory one-way valve 300. This allows the user to exchange airflow with the outside environment under normal circumstances through the inspiratory and expiratory one-way valves when using the respiratory function training mask for respiratory function training. The filter layer also provides resistance to inhalation to increase the user's inspiratory resistance effect, thereby achieving the training of respiratory muscles. The filter layer 500 can be made of sol-gel cloth; preferably, the filter layer seals the outlet end of the inspiratory one-way valve.
[0045] In this embodiment, the mask body is provided with straps 210 on both sides, so that the mask body can be worn on the face through the straps, covering the user's lips and nose. At this time, the user can only breathe through the inhalation one-way valve 300 and the exhalation one-way valve 400. The structure of the inhalation one-way valve and the exhalation one-way valve used in this embodiment can be similar to the one-way valve structure on the existing KN95 mask, except that the installation direction of the inhalation one-way valve and the exhalation one-way valve is reversed. In addition, the size of the inhalation one-way valve and the exhalation one-way valve in this embodiment is relatively small, so that their air passage is also correspondingly smaller, thereby giving the user a certain resistance when inhaling and exhaling, so that the user's respiratory muscles can be exercised better. The filter layer is provided at the inhalation one-way valve, which can further increase the inhalation resistance and improve the exercise effect. However, the filter layer may be blocked during use. If the blockage is so severe that it may cause the user to suffocate, the user can use the breathing safety valve to forcibly open the breathing passage with the outside world (i.e., the breathing safety valve reconstructs a breathing passage).
[0046] In this embodiment, the structural strength of the safety membrane must ensure that the respiratory function training mask will not break during normal operation, but will only break when the user takes a strong, deep breath (of course, the inhalation intensity corresponding to the breakage of the safety membrane can be divided into multiple levels according to the user's age group, so as to meet the training needs of respiratory muscles of users of different ages).
[0047] In this embodiment, the mask body can be made of silicone, latex or plastic, and the mask body has a good fit with the facial skin after being worn, so as to achieve good sealing between the mask body and the skin.
[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
