Detailed Implementation

[0026] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "inner", "outer" and other terms used in this utility model to indicate the orientation or positional relationship are based on the positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device and components referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0029] In current technology, users blow air into the trainer through a mouthpiece to measure lung capacity. However, exhaled air often contains a certain amount of moisture. If not cleaned in time, water will accumulate inside the trainer, affecting its effectiveness and hygiene.

[0030] To solve the above problems, such as Figures 1 to 4 As shown, this utility model embodiment provides a breathing trainer 100, including a housing 10, a mouthpiece 20, and a filter assembly 30. The housing 10 is provided with an insertion interface 11, and a gas guide 40 and a flow sensor are provided inside the housing 10. One end of the gas guide 40 faces the insertion interface 11, and the other end of the gas guide 40 faces the flow sensor. The mouthpiece 20 is provided with an air outlet 21. The mouthpiece 20 is detachably inserted into the insertion interface 11, and the mouthpiece 20 is inserted into the housing 10 and sleeved on the outer periphery of the gas guide 40. The mouthpiece 20 and the gas guide 40 enclose an airflow cavity. The filter assembly 30 is provided in the airflow cavity to intercept moisture in the airflow entering the airflow cavity.

[0031] In this embodiment, the housing 10 is the main body of the breathing trainer 100 and can be made of lightweight and durable materials, such as ABS plastic or aluminum alloy. One end of the housing 10 is provided with a plug interface 11, which is designed to match the size and shape of the mouthpiece 20 to ensure that the mouthpiece 20 can be securely inserted.

[0032] One end of the air nozzle 20 is provided with an air outlet 21 for easy air blowing by the user, while the other end is designed to be detachably inserted into the insertion interface 11 of the housing 10. After insertion, it can be tightly fitted around the outer periphery of the gas guide 40 so that the two together form a sealed airflow cavity.

[0033] The gas guide 40 is located inside the housing 10, with one end facing the insertion port 11 to guide the airflow entering from the mouthpiece 20; the other end faces the flow sensor located inside the housing 10 to ensure that the airflow can be smoothly and accurately monitored by the flow sensor. The flow sensor is used to detect and display the user's respiratory flow in real time, thereby detecting vital capacity.

[0034] The filter assembly 30 is one of the core components of this embodiment. It is located in the airflow cavity and its specific position is selected according to the airflow path. It can effectively intercept saliva and moisture in the airflow while maintaining smooth airflow, thereby preventing saliva and moisture from entering the housing 10.

[0035] Based on the above technical solution, the user blows air into the housing 10 through the air outlet 21 of the mouthpiece 20. The airflow first enters the airflow cavity formed by the mouthpiece 20 and the gas guide 40. Inside the airflow cavity, the filter assembly 30 intercepts saliva and moisture in the airflow. The purified airflow continues to flow to the other end of the gas guide 40, and the flow rate is detected by the flow sensor, thereby detecting lung capacity. After the breathing trainer 100 has been used several times, the mouthpiece 20 is removed, and the filter assembly 30 is cleaned to avoid the accumulation of saliva, bacteria, and other contaminants, greatly improving the cleanliness of the breathing trainer 100.

[0036] In one implementation, the filter assembly 30 is detachably connected to the gas guide 40.

[0037] Understandably, during the long-term use of the breathing trainer 100, the filter component 30, as a key component for intercepting moisture in the airflow, will gradually accumulate impurities such as saliva and bacteria, affecting its filtration effect and airflow.

[0038] Based on this, in this embodiment, the filter assembly 30 is designed to be detachably connected to the gas guide 40, such as through a snap-fit ​​connection or a magnetic connection. After long-term use, the air nozzle 20 can be removed, and then the filter assembly 30 can be removed from the gas guide 40. The air nozzle 20 and the filter assembly 30 can be cleaned separately, dried, and then reinserted for reuse. By designing the filter assembly 30 as detachable, it is convenient for users to clean or replace it regularly, ensuring hygiene.

[0039] As one implementation method, such as Figure 3 As shown, the filter assembly 30 includes a filter nozzle 31 and a filter screen 32. The filter nozzle 31 is partially fitted inside the gas guide member 40, and the filter nozzle 31 is provided with an airflow channel 33 that connects the air blowing nozzle 20 and the gas guide member 40. The filter screen 32 is located at one end of the airflow channel 33 near the gas guide member 40.

[0040] Specifically, the filter tip 31 is partially fitted inside the gas guide 40 to ensure a good connection and seal between the filter tip 31 and the air nozzle 20 and the gas guide 40. The filter tip 31 has an internal airflow channel 33 for guiding airflow. The external shape of the filter tip 31 matches the inner wall of the gas guide 40 to ensure stability and sealing after fitting. The filter screen 32 is located downstream of the filter tip 31 and can intercept saliva moisture in the airflow, preventing saliva moisture from entering the housing 10. When the user blows air into the trainer through the air nozzle 20, the airflow first enters the filter tip 31, then passes through the airflow channel 33. Saliva moisture in the airflow is intercepted by the filter screen 32, and finally enters the gas guide 40 and flows to the flow sensor.

[0041] As one implementation method, the filter tip 31 is made of a flexible material.

[0042] Specifically, the filter tip 31 can be made of silicone, rubber, or other flexible materials. The silicone or rubber can fit tightly against the gas guide 40, thereby improving the sealing performance. At the same time, because the filter tip 31 has a certain degree of elasticity, it can adapt to shape changes during installation and disassembly without being easily damaged.

[0043] In this embodiment, the filter tip 31 can be made entirely of flexible material, that is, the entire filter tip 31 can be made of silicone, or the filter tip 31 can be partially made of flexible material, such as the inside being rigid and the outside being flexible, which can also achieve a tight fit with the gas guide 40.

[0044] As one implementation method, such as Figure 3 and Figure 4 As shown, the filter nozzle 31 includes a first filter part 311 and a second filter part 312 connected to the first filter part 311. The first filter part 311 is sleeved in the gas guide member 40, and the second filter part 312 is sleeved in the air blowing nozzle 20. The second filter part 312 is provided with a V-shaped opening facing the air blowing port 21, and the V-shaped opening is connected to the airflow channel 33.

[0045] Specifically, the first filter section 311 is fitted inside the gas guide member 40 as a connecting part, so that the filter nozzle 31 can be pulled out from the gas guide member 40. At the position of the second filter section 312, that is, at the end of the filter nozzle 31 near the air mouth 20, a V-shaped opening is provided as a guiding structure. The angle and speed of airflow are optimized by the reduced opening structure.

[0046] In one embodiment, the filter assembly 30 includes a sterilization element (not shown in the figures), which is disposed in the airflow channel 33.

[0047] Specifically, the sterilization components can be materials or devices with specific sterilization functions, such as ultraviolet lamps, ozone generating modules, etc. These sterilization components are integrated in the airflow channel 33 to kill bacteria, viruses and other microorganisms in the airflow without affecting the smoothness of the airflow.

[0048] In one embodiment, the filter assembly 30 includes activated carbon (not shown in the figures), which is disposed in the airflow channel 33.

[0049] Specifically, activated carbon can be used alone or in combination with components such as filter nozzle 31 and filter screen 32. When airflow passes through airflow channel 33, activated carbon can fully adsorb odors.

[0050] As one implementation method, such as Figure 3 As shown, a filter 50 is provided at the end of the gas guide 40 facing the flow sensor, and the filter 50 is used to protect the flow sensor.

[0051] Specifically, during airflow transmission, the airflow may still carry tiny particles or impurities after passing through the filter assembly 30 and the gas guide 40. If these particles or impurities directly contact the flow sensor, they can degrade the sensor's performance. Therefore, a filter 50 is installed at the outlet of the gas guide 40 to further filter the airflow, thereby protecting the flow sensor.

[0052] In this embodiment, the filter element 50 can be made of a material with good air permeability and high filtration accuracy, such as a microporous membrane or fiber cloth. The pore size can be selected as needed to ensure that it can both filter and maintain smooth airflow. The filter element 50 can be designed as a detachable or replaceable structure for easy cleaning and replacement.

[0053] As one implementation method, such as Figure 1 , Figure 3 and Figure 4 As shown, the housing 10 is equipped with an electronic control board 60, and the surface of the housing 10 is equipped with a display component 70. The display component 70 and the flow sensor are electrically connected to the electronic control board 60.

[0054] Specifically, the housing 10 houses an electronic control board 60, which integrates and controls various circuits and functional modules of the equipment. The electronic control board 60 is the core control component of the equipment, responsible for receiving signals from components such as flow sensors, and processing and analyzing them. Simultaneously, the electronic control board 60 is also responsible for sending instructions to the display component 70, enabling the display component 70 to display airflow information within the airflow chamber, thereby determining the vital capacity.

[0055] For example, the display component 70 includes a display screen 71 and an indicator light 72. The display screen 71 may be in the form of an LCD screen, an LED screen, etc., to provide a clear and intuitive display effect; the indicator light 72 includes a plurality of LEDs, the number of LEDs lit up indirectly indicating the lung capacity.

[0056] As one implementation method, such as Figure 3 and Figure 4 As shown, the surface of the housing 10 is provided with a button 80, which is used to control the start and stop of the display component 70.

[0057] As one implementation method, such as Figure 4 As shown, the air nozzle 20 includes a mounting part 22 and an air blowing part 23 connected to the mounting part 22. The mounting part 22 is inserted into the housing 10 and sleeved on the outer periphery of the gas guide member 40. The air blowing port 21 is provided on the air blowing part 23, and the air blowing port 21 gradually decreases in size from the direction close to the mounting part 22 to the direction far away from the mounting part 22, so that the air blowing part 23 is flat.

[0058] Specifically, when installing the air nozzle 20, the mounting part 22 is inserted into the housing 10 and fitted onto the outer periphery of the gas guide 40. The air blowing part 23 protrudes from the housing 10. Air is blown into the air blowing part 23 through the air blowing port 21 by holding it in the mouth, thereby measuring lung capacity. The air blowing part 23 is flat, with a slender and rounded shape, providing a good tactile feel, which increases the convenience of operation and enhances the user experience.

[0059] As one implementation method, such as Figure 4As shown, the housing 10 includes an upper cover 14 and a lower cover 15. The upper cover 14 and the lower cover 15 form a cavity for accommodating components such as the electronic control board 60. A ball-shaped shell 12 is fitted onto one end of the housing 10, and an insertion interface 11 is located on the ball-shaped shell 12. A rubber collar structure 13 is then fitted between the ball-shaped shell 12 and the upper cover 14 and the lower cover 15 to enhance the tactile feel. The ball-shaped shell 12 can be replaced with other different shapes, such as a bear shape, to improve its aesthetics.
