[0050] 1. This utility model discloses an integrated breathing training and testing device with expiratory temperature measurement function. By providing an air intake component for controlling the air intake speed in the air chamber and an air exhaust component for controlling the air exhaust speed in the air chamber, different air intake resistance and / or air exhaust resistance can be achieved to adjust the breathing resistance during the user's breathing training (i.e., adjust the magnitude of the breathing resistance), help the user to perform inhalation and / or air intake training, and improve the breathing training effect.

The present invention provides a breathing training and testing integrated device, wherein the second air inlet of the air inlet component has several holes of different diameters arranged circumferentially, and the second air outlet of the air outlet component has several holes of different diameters arranged circumferentially. By adjusting the diameter of the second air inlet in the air inlet component and the diameter of the second air outlet in the air outlet component, the corresponding air inlet flow rate and air outlet flow rate are selected to control different air inlet flow rates and air outlet flow rates, thereby achieving different air inlet resistance and air outlet resistance. Then, the user blows and / or inhales through the mouthpiece to achieve breathing training.

[0052] 3. This utility model discloses an integrated breathing training and testing device with expiratory temperature measurement function. The first and second rotating covers are flattened starfish shapes, facilitating the fit of the first and second wrists of both covers against the outer surface of the spherical segment of the housing. This results in a more aesthetically pleasing overall shape for the breathing training device without hindering the rotation of the first and / or second rotating covers. The arc-shaped transition between adjacent wrists makes it easier for the operator to place their fingers and apply rotational force, causing the first and / or second rotating covers to rotate. Furthermore, the starfish shape design increases the distance between the two wrists facing opposite directions, ensuring that the patient can simultaneously observe whether the markings on the first and second wrists of both covers align with the baseline on the spherical segment of the housing, thus understanding and maintaining the currently selected inlet / outlet and outlet settings, ensuring the stability of the breathing training intensity.

[0053] 4. This utility model discloses an integrated breathing training and testing device with expiratory temperature measurement function. By setting up a pressure sensor, a control unit, and a display screen, the control unit obtains information such as the number of breaths, the effective number of breaths, the user's vital capacity, and the maximum airflow velocity based on the gas pressure feedback from the pressure sensor. This information is then displayed to the user on the display screen so that the user or medical staff can judge the effect of the user's breathing training using this integrated breathing training and testing device, that is, to test the effect of the breathing training in order to understand the quality of the breathing training.

[0054] 5. This utility model provides a breathing training and testing integrated device with expiratory temperature measurement function. By setting a temperature sensor, the expiratory temperature inside the shell is measured. Then, the temperature sensor feeds back the expiratory temperature to the control unit, which displays the expiratory temperature on the display screen. Attached Figure Description

[0084] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0085] See Figures 1 to 20 Specific embodiment 1: This embodiment 1 provides a breathing training and testing integrated device including a housing 1 with an internal air chamber 150, a blow-in mouthpiece 200, an air intake component 300 for controlling the air intake speed in the air chamber 150, and an air outlet component 400 for controlling the air outlet speed in the air chamber 150. The blow-in mouthpiece 200, the air intake component 300 and the air outlet component 400 are all connected to the housing 1. The first air passage 206 of the blow-in mouthpiece 200 is connected to the air chamber 150.

[0086] The housing 100 contains a pressure sensor 500 for monitoring the gas pressure within the air chamber 150, a temperature sensor 700 for monitoring the gas temperature within the air chamber 150, and a control unit 600. A display screen 601 is mounted on the surface of the housing 100. The pressure sensor 500 feeds back the gas pressure within the air chamber 150 to the control unit 600, which then controls the operation of the display screen 601. For example, the control unit 600 determines the number of breaths taken and the number of effective breaths based on the feedback from the pressure sensor 500 (e.g., the pressure sensor 500 is a differential pressure sensor, continuously capturing pressure ranges or pressure differences; if the pressure range is continuously...). A breath lasting longer than 0.5 seconds is considered effective breathing, while a breath lasting less than or equal to 0.5 seconds is considered ineffective breathing. The specific values ​​are displayed on screen 601 for the user to understand and use to test or monitor the quality of breathing training. For example, the control unit 600 calculates the user's vital capacity based on feedback from the pressure sensor 500. When both the intake and exhaust components 300 and 400 are set to zero, and there is no resistance during exhalation and inhalation, the control unit 600, based on feedback from the pressure sensor 500, determines the maximum gas flow rate, allowing the user to judge whether their breathing depth is sufficient. The temperature sensor 700 feeds back the gas temperature within the air chamber 150 to the control unit 600, which displays the temperature on screen 601, reminding the user of the exhaled temperature and helping them determine if they have a fever (e.g., ≥36.7℃). If a fever is detected, timely treatment can be initiated to avoid delays in medical care.

[0087] The housing 1 includes a spherical segment 110, which is hollow inside, and a hollow tubular neck segment 130. The spherical segment 110 and the neck segment 130 are connected by a hollow transition segment 140. The hollow portions of the spherical segment 110, the transition segment 140, and the neck segment 130 are connected to form an air chamber 150. The neck segment 130 is connected to a mouthpiece 200, and the hollow portion of the neck segment 130 is connected to the first airway 206 of the mouthpiece 200. The overall design of the breathing training device is more aesthetically pleasing, and the user finds it more comfortable to hold the spherical segment 110 during use. The design of the spherical section 110 allows for a larger air chamber 150 in the breathing training device. The neck section 130, connecting to the mouthpiece 200, also gives the breathing training device a certain length. The first wrist 314 of the first rotating cover 310 and the second wrist 414 of the second rotating cover 410 can both fit against the spherical surface of the spherical section 110. During use, the user can exhale and inhale simultaneously using the mouthpiece 200 while visually observing the corresponding indicator numbers on the first wrist 314 and the second wrist 414, ensuring correct air intake and exhaust settings and more precise training results. The transition section 140 can adopt an inwardly concave arc transition, forming a vase-like shape, making the overall design of the breathing training device more aesthetically pleasing.

[0088] The spherical section 110 of the housing 100 is provided with a first mounting plate 164. The pressure sensor 500 and the control unit 600 are mounted on the first mounting plate 164. The control unit 600 is connected to the display screen 601. The space inside the spherical section 110 of the housing 100 is reasonably divided, making the structure more compact.

[0089] The spherical section 110 of the housing 1 is provided with a first partition plate 111 and a second partition plate 119. A first space 118 for installing an air intake assembly 300 is formed between the first partition plate 111 and the housing 1. The first partition plate 111 is provided with a first air intake hole 112. A second space 126 for installing an air outlet assembly 400 is formed between the second partition plate 119 and the housing 1. The second partition plate 119 is provided with a first air outlet hole 120. A third space is formed between the first partition plate 111, the second partition plate 119 and the housing 1. A third partition plate 1 is also provided in the spherical section 110 and the neck section 130 of the housing 100. 60. The third partition plate 160 divides the third space into an installation space 170 for installing the pressure sensor 500 and the control unit 600 and an airflow space 180 for gas flow. The airflow space 180 is part of the air chamber 150. The airflow space 180 is connected to the first air inlet 112, the first air outlet 120, the hollow part of the neck section 130, the hollow part of the transition section 140, and the first air passage 206 of the blow-in nozzle 200.

[0090] An auxiliary partition plate 190 is provided on the opposite side of the third partition plate 160 of the neck section 130, facing away from the airflow space 180. The third partition plate 160 and the auxiliary partition plate 190 completely separate the installation space 170 and the airflow space 180, preventing gas in the airflow space 180 from entering the installation space 170. The temperature sensor 700 is connected to the auxiliary partition plate 190, and the temperature sensor 700 is connected to the control unit 600 via a connecting cable 701.

[0091] The first air tube 501 of the pressure sensor 500 is connected to the airflow space 180 through the first air port 161 of the third partition plate 160, and the second air tube 502 of the pressure sensor 500 is connected to the airflow space 180 through the second air port 162 of the third partition plate 160.

[0092] A grid 163 is provided on one side of the third partition plate 160 of the neck section 130 facing the airflow space 180. The first air port 161 and the second air port 162 are located on both sides of the grid 163. The grid 163 helps to distribute the airflow near the first air port 161 and the second air port 162 more evenly, and improves the accuracy of the pressure sensor 500 in detecting the gas pressure on both sides of the grid 163.

[0093] The housing 1 also includes a control button 602 for connecting to the control unit 600, a charging port (not shown in the attached drawings), and a player (not shown in the attached drawings). A battery is also mounted on the first mounting plate 164. The charging port provides external power to the battery, which in turn powers the control unit 600 (e.g., the control unit's circuit board) and the display screen 601. The control button 602 controls the on / off state of the display screen and the objects displayed on the screen (e.g., respiratory rate, effective respiratory rate, vital capacity, maximum respiratory flow rate, etc.).

[0094] Preferably, the end of the mouthpiece 200 away from the housing 1 is the first end 201 of the mouthpiece. The outer side of the first end 201 of the mouthpiece is provided with a biting positioning protrusion 207, for example, the biting positioning protrusion 207 is a long strip protrusion (similar to a rib), distributed along the circumference and / or axial direction of the mouthpiece 200, used to guide the teeth to bite in a fixed position, while enhancing the structural strength of the mouthpiece 200, thus limiting the position and preventing slippage.

[0095] The neck section 130 of the housing 1 is detachably connected to the mouthpiece 200. By replacing the mouthpiece 200 for different users, multiple people can share it, maintaining hygiene. For example, the inner wall of the neck section 130 of the housing 1 is provided with a slot 131, and the outer side of the mouthpiece 200 corresponding to one end of the housing 1 (i.e., the second end 202 of the mouthpiece) is provided with a protruding snap-fit ​​part 204 and a third step part 203. When the mouthpiece 200 is inserted into the hollow part of the neck section 130, the neck section 130 engages with the third step part 203. The outer diameter of the neck section 130 is equal to or close to the outer diameter of the mouthpiece 200, making the connection between the neck section 130 and the mouthpiece 200 smoother and the overall appearance of the breathing trainer device more aesthetically pleasing. Then, rotate the nozzle 200 so that the locking part 204 engages with the slot 131. A click sound indicates that the neck section 130 and the nozzle 200 are successfully connected, helping to secure the housing 1 and the nozzle 200. When it is necessary to disassemble the neck section 130 and the nozzle 200, simply rotate the nozzle 200 so that the locking part 204 slides out of the slot 131, and then pull the nozzle 200 outward to separate the two. The nozzle 200 also has a clearance groove 205 at one end of the housing 1 (i.e., the second end 202 of the nozzle), providing space to allow for radial deformation of the end of the nozzle 200 where the locking part 204 is located.

[0096] The neck section 130 of the housing 1 and the mouthpiece 200 are both elliptical in cross-section. This ensures that the shapes of the neck section 130 and the mouthpiece 200 correspond, the connection between the two is smooth and aesthetically pleasing, and the elliptical mouthpiece 200 is more stable when it is held in place, preventing the mouthpiece 200 from rotating circumferentially.

[0097] The housing 1 has a first opening 115 at the location corresponding to the first space 118. The air intake assembly 300 includes an air intake valve 320 installed in the first space 118 and a first rotating cover 310 with a first vent 312. The first rotating cover 310 is flat and starfish-shaped. The middle part of the first rotating cover 310 is installed at the first opening 115. The first wrist 314 of the first rotating cover 310 is attached to the outer surface of the housing 1 (i.e., the outer surface of the spherical segment 110 of the housing 1). The housing 1 has a second opening 123 at the location corresponding to the second space 126. The air outlet assembly 400 includes an air outlet valve 420 installed in the second space 126 and a second rotating cover 410 with a second vent 412. The second rotating cover 410 is flat and starfish-shaped. The middle part of the second rotating cover 410 is installed at the second opening 123. The second wrist 414 of the second rotating cover 410 is attached to the outer surface of the housing 1 (i.e., the outer surface of the spherical segment 110 of the housing 1).

[0098] Both the first wrist 314 of the first rotating cover 310 and the second wrist 414 of the second rotating cover 410 can have six wrists. The first wrist 314 and the second wrist 414 are both attached to the surface of the shell 1 of the spherical segment 110, making the overall shape of the breathing training device more aesthetically pleasing without affecting the rotation of the first rotating cover 310 and / or the second rotating cover 410. The connection between adjacent wrists is an arc transition, which makes it easier for the operator to place their fingers and apply rotational force to make the first rotating cover 310 and / or the second rotating cover 410 rotate. The spherical segment 110 of the shell 1 is provided with reference lines on both sides, namely the first reference line 127-1 and the second reference line 127-2. The plane formed by the two reference lines passes through the center of the spherical segment 110, the center of the first air inlet 112, and the center of the second air inlet 322.

[0099] The starfish-shaped design, with increased distance between the two opposing wrists, ensures that the patient can simultaneously observe whether the markings on the first wrist 314 of the first rotating cover 310 and the second wrist 414 of the second rotating cover 410 are aligned with the reference line on the spherical segment 110 of the housing 1 (e.g., ...). Figure 2 The first baseline 127-1 (in this embodiment 1, the intake assembly 300 and the exhaust assembly 400 are both selected to the zero position) is used to understand and maintain the currently selected intake and exhaust positions, ensuring the stability of the breathing training intensity. For example, the middle part of the first rotating cover 310 is circular, and the distance from the center of the middle part of the first rotating cover 310 to the end of the first wrist 314 is greater than one-eighth of the circumference of the large circle of the spherical segment 110 of the housing 1. The middle part of the second rotating cover 410 is circular, and the distance from the center of the middle part of the second rotating cover 410 to the end of the second wrist 414 is greater than one-eighth of the circumference of the large circle of the spherical segment 110 of the housing 1. In this way, the distance between the ends of the two first wrists 314 in opposite directions is greater than one-quarter of the circumference of the great circle of the sphere segment 110 (i.e., the circle formed by the cross-section of the sphere through the center of the sphere); the distance between the ends of the two second wrists 414 in opposite directions is greater than one-quarter of the circumference of the great circle of the sphere segment 110 (i.e., the circle formed by the cross-section of the sphere through the center of the sphere).

[0100] The shape of the first vent 312 and the second vent 412 can be either circular or fan-shaped. The fan-shaped first vent 312 and the second vent 412 maximize the opening area of ​​the two holes and increase the gas throughput per unit time.

[0101] The intake valve 320 includes a first valve cover 321, a first valve seat 329, and a first valve plate 327. The first valve cover 321 is provided with several second intake holes 322 of different diameters arranged circumferentially. The second intake holes 322 of different diameters correspond to different intake resistances. The smaller the diameter, the greater the resistance, and the larger the diameter, the less the resistance. Users can select the second intake hole 322 of the corresponding diameter for inhalation training, thereby increasing the strength and endurance of the inspiratory muscles (diaphragm and intercostal muscles) through adjustable resistance training. The side of the first valve cover 321 facing the first valve seat 329 is connected to one end of the first rod 326. The first rod 326 includes a first rod A segment 326-1 corresponding to the first valve cover 321 and a first rod B segment 326-2 corresponding to the first valve seat 329. The diameter of the first rod B segment 326-2 is smaller than the diameter of the first rod A segment 326-1, and the height of the first rod B segment 326-2 is equivalent to the sliding stroke range of the first valve plate 327. The first valve cover 321 has a first annular protrusion 323 on the side facing the first valve seat 329, and the outer side of the first annular protrusion 323 has a first limiting protrusion 325.

[0102] The first valve seat 329 is open-topped, cylindrical in shape. The bottom 334 of the first barrel of the first valve seat 329 has a third vent 335, a first pin hole 336, and a first hole 337. The end of the first barrel portion 330 of the first valve seat 329 has a first limiting groove 331. The first limiting protrusion 325 matches the first limiting groove 331. When the first valve cover 321 covers the first valve seat 329, rotating the first valve cover 321 causes the first limiting protrusion 325 to correspond to and embed into the first limiting groove 331, and the first annular protrusion 323 embeds into the first barrel portion 330 of the first valve seat 329. The first rod segment B 326-2, after being sleeved onto the first valve plate 327, is inserted into the first hole 337. The area of ​​the first valve plate 327 covers the entire third vent 335. The first valve plate 327 slides up and down along the first rod B section 326-2. When the patient inhales, the air outlet assembly 400 (i.e., the air outlet valve 420) closes, and the pressure inside the air chamber 150 of the housing 1 decreases. Under the action of external atmospheric pressure, the first valve plate 327 slides along the first rod B section 326-2 toward the first rod A section 326-1 until the first valve plate 327 stops sliding against the end of the first rod A section 326-1. A channel for gas flow (i.e., the second airway 338) is created between the first valve plate 327 and the bottom 334 of the first barrel of the first valve seat 329. At this time, the first valve plate 327 moves away from the third vent 335, and external air enters the first valve seat 329 through the first vent 312, the third vent 335, and the second airway 338, and then enters the air chamber 150 of the housing 1 through the second air inlet 322 and the first air inlet 112, realizing the air intake function of the breathing training device.

[0103] When the patient exhales, the gas pressure in the air chamber 150 of the housing 1 increases. The gas in the air chamber 150 enters the first valve seat 329 through the first air inlet 112 and the second air inlet 322. The high-pressure gas presses the first valve plate 327 along the first rod B section 326-2, sliding towards the bottom 334 of the first barrel of the first valve seat 329 until the first valve plate 327 is in close contact with the bottom 334 of the first barrel of the first valve seat 329. The first valve plate 327 covers all the third vents 335, blocking the gas flow and realizing the closed air intake function of the breathing training device.

[0104] The first rotating cover 310 has a first pin 313 on one side of the housing 1, and the first pin 313 matches the first pin hole 336. When the first pin 313 is inserted into the first pin hole 336, the first rotating cover 310 and the first valve cover 321 are connected and fixed, which facilitates the first rotating cover 310 to drive the first valve seat 329 to rotate, and the first valve seat 329 to drive the first valve cover 321 to rotate, which facilitates the alignment of the second air inlet holes 322 of different sizes (i.e., different diameters) on the first valve cover 321 with the first air inlet hole 112, which facilitates the control of different air intake speeds and achieves different air intake resistance. The first rotating cover 310, the first valve seat 329, and the first valve cover 321 rotate synchronously, and the corresponding first vent hole 312 and third vent hole 335 always maintain a one-to-one correspondence, that is, one first vent hole 312 overlaps one third vent hole 335.

[0105] A first positioning plate 113 is provided on the inner side wall of the shell 1 corresponding to the first space 118. A first positioning groove 114 is provided on the inner end of the first positioning plate 113. The first positioning plate 113 between adjacent first positioning grooves 114 abuts against the first barrel part 330 of the first valve seat 329, restricting the radial movement of the first valve seat 329 and the first valve cover 321, ensuring that the positions of the first air inlet 112 and the corresponding second air inlet 322 are accurately aligned, and accurately controlling the air intake speed.

[0106] The air intake valve 320 also includes a first positioning post 328 and a first elastic part (such as a spring, not shown in the attached figure). One end of the first elastic part is connected to the inner wall of the first barrel part 330, and the other end of the first elastic part is connected to the first positioning post 328. The first annular protrusion 323 is provided with a first fixing groove 324 for fixing the first positioning post 328; the first barrel part 330 of the first valve seat 329 is also provided with a first through hole 332. After the first positioning post 328 passes through the first through hole 332, it matches with the first positioning groove 114. That is, as the first valve seat 329 rotates, the first positioning post 328 slides out from different first positioning grooves 114 and embeds into the next first positioning groove 114. This can prevent the first valve seat 329 and the first valve cover 321 from rotating circumferentially during use. When the first positioning post 328 is embedded in the first positioning groove 114, it will make a click sound to indicate to the user that the first rotating cover 310 has been rotated into place and the second air intake hole 322 of the corresponding diameter is aligned with the first air intake hole 112, making it simpler and more convenient to use.

[0107] The diameter of the first air inlet 112 is greater than or equal to the maximum diameter of the second air inlet 322. The maximum diameter of the second air inlet 322 refers to the diameter of the second air inlet 322 with the largest diameter. This ensures that the second air inlet 322 with the largest diameter can fully function (i.e. achieve the maximum air intake speed), so that the second air inlets 322 with other diameters can also fully function (i.e., achieve their maximum air intake speed).

[0108] The first valve cover 321 abuts against the first partition plate 111. The outer side of the first barrel portion 330 of the first valve seat 329 is provided with a second annular protrusion 333. The first opening 115 of the housing 1 is provided with a third annular protrusion 116. The inner side of the third annular protrusion 116 is provided with a first step portion 117. The first step portion 117 matches the second annular protrusion 333. That is, when the air intake assembly 300 is installed in the first space 118, the first step portion 117 presses on the second annular protrusion 333, and the first valve cover 321 abuts against the first partition plate 111. The first step portion 117 and the first partition plate 111 clamp the air intake valve 320, thereby realizing the installation and fixation of the air intake valve 320.

[0109] The middle portion of the first rotating cover 310 facing the side of the housing 1 has a fourth annular protrusion 311, which fits onto the outer side of the third annular protrusion 116. This design helps to fix the position of the first rotating cover 310, especially when the first rotating cover 310 rotates, the position between the first rotating cover 310 and the first opening 115 does not move, ensuring that the relative position between the first arm 314 of the first rotating cover 310 and the second air inlet 322 does not change, and ensuring the accuracy of the first rotating cover 310 in selecting the second air inlet 322.

[0110] The exhaust valve 420 includes a second valve cover 421, a second valve seat 429, and a second valve plate 427. The second valve cover 421 has several second exhaust holes 422 with different diameters arranged circumferentially. The second exhaust holes 422 with different diameters correspond to different exhaust resistances. The smaller the diameter, the greater the resistance, and the larger the diameter, the less the resistance. Users can select the second exhaust hole 422 with the corresponding diameter to perform exhalation training, thereby increasing the strength and endurance of the expiratory muscles (abdominal wall muscles and intercostal muscles) through adjustable resistance training. The side of the second valve cover 421 facing the first valve seat 329 is connected to one end of the second rod 426. The other end of the second rod 426 is provided with a limiting part 426-1. The second valve plate 427 is sleeved on the second rod 426. The limiting part 426-1 presses the second valve plate 427 tightly onto the second air outlet 422 of the second valve cover 421. The side of the second valve cover 421 facing the second valve seat 429 is provided with a fifth annular protrusion 423. The outer side of the fifth annular protrusion 423 is provided with a second limiting protrusion 425. When the patient exhales, the air intake assembly 300 (i.e., the air intake valve 320) closes, and the first valve plate 327 adheres tightly to and covers the third air vent 335, blocking the air intake. When gas flows through valve 320, the air intake assembly 300 (i.e., air intake valve 320) closes, and the gas pressure in the air chamber 150 of housing 1 increases. The gas in the air chamber 150 passes through the first air outlet 120 and the corresponding second air outlet 422, lifting the second valve plate 427 around its perimeter, thus creating a channel (i.e., the third air passage 437) for gas flow between the second valve plate 427 and the second air outlet 422. The gas in the air chamber 150 passes through the first air outlet 120 and the corresponding second air outlet 422 and the third air passage 437 into the second valve seat 429, and then enters the outside air through the fourth vent 435 and the second vent 412, thus realizing the air output function of the breathing training device.

[0111] When the patient inhales, the pressure inside the air chamber 150 of the housing 1 decreases. Under the action of external atmospheric pressure, the second valve plate 427 adheres tightly to and covers the second air outlet 422, blocking the flow of gas and realizing the function of closing the air outlet of the breathing training device.

[0112] The second valve seat 429 is open-topped and barrel-shaped. The bottom 434 of the second barrel of the second valve seat 429 is provided with a fourth vent hole 435 and a second pin hole 436. The end of the second barrel body 430 of the second valve seat 429 is provided with a second limiting groove 431. The second limiting protrusion 425 and the second limiting groove 431 are matched. When the second valve cover 421 is placed on the second valve seat 429 (inverted in the attached figure), the second valve cover 421 is rotated so that the second limiting protrusion 425 is embedded in the second limiting groove 431 and the fifth annular protrusion 423 is embedded in the barrel body of the second valve seat 429.

[0113] The second rotating cover 410 has a second pin 413 on one side of the housing 1, and the second pin 413 matches the second pin hole 436. When the second pin 413 is inserted into the second pin hole 436, the second rotating cover 410 and the second valve cover 421 are connected and fixed, which facilitates the second rotating cover 410 to drive the second valve seat 429 to rotate, and the second valve seat 429 to drive the second valve cover 421 to rotate. This facilitates the alignment of the second vent holes 422 of different sizes (i.e., different diameters) on the second valve cover 421 with the first vent hole 120, which facilitates the control of different venting speeds and achieves different venting resistances. The second rotating cover 410, the second valve seat 429, and the second valve cover 421 rotate synchronously, and the corresponding second vent hole 412 and the corresponding fourth vent hole 435 always maintain a one-to-one correspondence, that is, one second vent hole 412 overlaps one fourth vent hole 435.

[0114] A second positioning plate 121 is provided on the inner side wall of the housing 1 corresponding to the second space 126. A second positioning groove 122 is provided on the inner end of the second positioning plate 121. The second positioning plate 121 between adjacent second positioning grooves 122 abuts against the second barrel part 430 of the second valve seat 429, restricting the radial movement of the second valve seat 429 and the second valve cover 421, ensuring that the positions of the first air outlet 120 and the corresponding second air outlet 422 are accurately aligned, and accurately controlling the air outlet speed.

[0115] The vent valve 420 also includes a second positioning post 428 and a second elastic part. One end of the second elastic part is connected to the inner side wall of the second barrel body 430, and the other end of the second elastic part is connected to the second positioning post 428.

[0116] The fifth annular protrusion 423 is provided with a second fixing groove 424 for fixing the second positioning post 428; the second barrel part 430 of the second valve seat 429 is also provided with a second through hole 432. After the second positioning post 428 passes through the second through hole 432, it matches the second positioning groove 122. That is, as the second valve seat 429 rotates, the second positioning post 428 slides out from different second positioning grooves 122 and is embedded in the next second positioning groove 122. This can prevent the second valve seat 429 and the second valve cover 421 from rotating circumferentially during use. When the second positioning post 428 is embedded in the second positioning groove 122, it will make a click to indicate to the user that the second rotating cover 410 has been rotated into place and the second vent hole 422 of the corresponding diameter is aligned with the first vent hole 120, making it simpler and more convenient to use.

[0117] The diameter of the first vent 120 is greater than or equal to the maximum diameter of the second vent 422; the maximum diameter of the second vent 422 refers to the diameter of the second vent 422 with the largest diameter. Ensuring that the second vent 422 with the largest diameter can function fully (i.e., achieve maximum airflow velocity) will also ensure that the other vents 422 with different diameters can function fully (i.e., achieve their maximum airflow velocity).

[0118] The second valve cover 421 abuts against the second partition plate 119. The outer side of the second barrel portion 430 of the second valve seat 429 is provided with a sixth annular protrusion 433. The second opening 123 of the housing 1 is provided with a seventh annular protrusion 124. The inner side of the seventh annular protrusion 124 is provided with a second step portion 125, which matches the sixth annular protrusion 433. When the air outlet assembly 400 is installed in the second space 126, the second step portion 125 presses against the sixth annular protrusion 433, and the second valve cover 421 abuts against the second partition plate 119. The second step portion 125 and the second partition plate 119 clamp the air outlet valve 420, thereby achieving the installation and fixation of the air outlet valve 420.

[0119] The middle portion of the second rotating cover 410 facing the side of the housing 1 has an eighth annular protrusion 411, which fits onto the outer side of the seventh annular protrusion 124. This design helps to fix the position of the second rotating cover 410, especially when the second rotating cover 410 rotates, the position between the second rotating cover 410 and the second opening 123 does not move, ensuring that the relative position between the second wrist 414 of the second rotating cover 410 and the second vent 422 does not change, and ensuring the accuracy of the second rotating cover 410 in selecting the second vent 422.

[0120] The number of second air inlets 322 and second air outlets 422 is the same. Second air inlets 322 and second air outlets 422 of the same diameter are correspondingly arranged, for example, in a mirror image arrangement. The six first wrists 314 of the first rotating cover 310 are configured to correspond to the first numerical identifier 315 of the corresponding second air inlet 322. The six second wrists 414 of the second rotating cover 410 are configured to correspond to the second numerical identifier 415 of the corresponding second air outlet 422. The first numerical identifier 315 and the second numerical identifier 415 are also correspondingly arranged, for example, in a mirror image arrangement.

[0121] In this embodiment 1, a breathing training and testing integrated device is used. The user first rotates the first rotating cover 310 and the second rotating cover 410 to select the corresponding inlet and outlet airflow speed levels, controlling different inlet and outlet airflow speeds to achieve different inlet and outlet airflow resistances. Then, the user blows and / or inhales through the mouthpiece 200 to achieve breathing training. The pressure sensor 500 feeds back the gas pressure within the airflow space 180 to the control unit 600, which judges and displays information such as the number of breaths, effective breaths, maximum vital capacity, and maximum airflow speed on the display screen 601, allowing the user to check the effect and quality of the breathing training. The control unit 600 can also control a player (e.g., a speaker) to play prompts.

[0122] Meanwhile, the temperature sensor 700 feeds back the gas temperature (especially the user's exhaled gas) in the airflow space 180 to the control unit 600. The control unit 600 displays the user's exhaled gas temperature on the display screen 601 and reminds the user of the exhaled gas temperature. If the exhaled gas temperature is too high (e.g., ≥36.7℃), the control unit 600 can also control the player (e.g., speaker) to play a prompt sound, so that the user can judge whether he or she has a fever and can receive timely treatment to avoid delaying medical treatment.
