[0022] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] See Figures 1 - 3 , an embodiment of the present utility model provides a breathing trainer, which includes a housing 1, an air chamber component 3 and a PCB board 4. Among them, the housing 1 is in a long strip shape. The housing 1 includes a front face 1a, a rear face 1b and a top face (not marked in the figure) connecting the front face 1a and the rear face 1b. A blowing nozzle 2 is provided on the top face. The air chamber component 3 is arranged inside the housing 1. The air chamber component 3 includes an intake port 31 communicating with the blowing nozzle 2 and an air chamber 32 communicating with the intake port 31. An air leakage hole 321 and a detection hole 322 are formed in the side wall of the air chamber 32. The air leakage hole 321 is used to allow the airflow entering from the blowing nozzle 2 to flow out of the housing 1 through the air leakage hole 321, so as to form a complete airflow channel inside and outside the housing 1. The PCB board 4 is arranged inside the housing 1. An air pressure detection sensor 41, a display screen 42 and a battery 43 are provided on the PCB board 4. The air pressure detection sensor 41 is located inside the detection hole 322 for detecting the air pressure in the air chamber 32, so that the user can obtain the measured data during blowing. The display screen 42 is arranged on the front face 1a and is located on the side far from the top face. The display screen 42 is used to at least display the data and / or guiding pattern after the measured air pressure size is processed and converted. The battery 43 is used to supply power to the PCB board 4.

[0024] By setting the housing 1 in a long strip shape and arranging the display screen 42 on the front face 1a of the housing 1 and at a position far from the top face, when the user blows on the blowing nozzle 2, the user can observe the change of the test data and / or the guiding pattern in real time, so that the user can obtain effective training data in real time, which helps to improve the training effect.

[0025] For the breathing trainer provided by the present utility model, when the user blows on the blowing nozzle 2, the user can at least observe the test data and / or the guiding pattern in real time, so that the user can obtain effective training data in real time, which helps to improve the training effect of the user.

[0026] Specifically, a transparent panel 13 is provided on the front surface 1a of the housing 1. The transparent panel 13 corresponds to the display screen 42, so that the display screen 42 can display data or patterns through the transparent panel 13. A groove 14 for accommodating the transparent panel 13 is provided on the front surface 1a of the housing 1, so that the transparent panel 13 can be flush with the surface of the housing 1, maintaining the consistency of the external structure of the breathing trainer.

[0027] Furthermore, a control switch 44 is also provided on the PCB board 4. The control switch 44 is located on one side of the display screen 42 and close to the top surface. A key 5 corresponding to the control switch 44 is provided on the front surface 1a of the housing 1. The key 5 is provided on the front surface 1a, which facilitates the user to operate the key 5 during use and improves the user experience.

[0028] In this embodiment, the control switch 44 can be, but is not limited to, a function switch for turning on and off the breathing trainer and / or adjusting the parameters and functions of the breathing trainer. Correspondingly, the user can control the control switch 44 inside the housing 1 by setting the corresponding key 5.

[0029] Furthermore, a training program is embedded in the PCB board 4. A speaker 45 is also provided on the PCB board 4. The speaker 45 is used to broadcast the voice of the training program to guide the training. In this way, the user can train by combining voice prompts with guiding patterns, which can improve the training effect and user experience of the user.

[0030] Furthermore, a sound outlet hole 11 is provided on the back surface 1b of the housing 1. The speaker 45 is close to the top surface. The sound outlet hole 11 corresponds to the speaker 45. Setting the sound outlet hole 11 on the back surface 1b of the housing 1 can prevent the sound outlet hole 11 from facing the user on the front surface 1a during use, resulting in overly harsh sounds and affecting the use experience. And setting the speaker 45 close to the top surface and the sound outlet hole 11 corresponding to the speaker 45 enables the sound emitted by the speaker 45 to be closer to the user to ensure that the sound transmitted by the speaker 45 is clear enough. At the same time, it can also stagger the positions of the speaker 45 and the display screen 42, improving the reasonable layout of the internal structure of the breathing trainer, making the structure of the breathing trainer smaller and more convenient to carry.

[0031] Furthermore, the air release hole 321 is provided on the side of the air chamber 32 facing the back surface 1b of the housing 1. An air outlet channel 12 is provided on the back surface 1b of the housing 1. The air outlet channel 12 is communicated with the air release hole 321. In this way, when the user blows air, the back surface 1b of the breathing trainer faces downwards. The air release hole 321 and the air outlet channel 12 provided on the back surface 1b are beneficial for the saliva flowing in with the blown air to flow out of the housing 1 under the action of gravity, which can prevent the saliva from corroding the electronic components inside the housing 1, thereby improving the service life of the breathing trainer.

[0032] Furthermore, the housing 1 further includes a bottom surface 1c that connects the back surface 1b and the front surface 1a and is opposite to the top surface. A charging port 6 is provided on the bottom surface 1c, and the charging port 6 is electrically connected to the PCB board 4. Setting the charging port 6 can charge the battery 43, thereby ensuring the recyclability of the breathing trainer and reducing the energy cost.

[0033] Specifically, the PCB board 4 includes a first PCB board unit 4a and a second PCB board unit 4b that are electrically connected. The first PCB board unit 4a and the second PCB board unit 4b are sequentially arranged from the top surface in a direction away from the top surface. One end of the first PCB board unit 4a close to the top surface extends to the detection hole 322, and the air pressure detection sensor 41 is provided on the first PCB board unit 4a and corresponds to the detection hole 322. Compared with the integrated PCB board 4, setting the PCB board 4 as the split first PCB board unit 4a and second PCB board unit 4b can facilitate the adjustment of the installation position of the PCB board 4, and can optimize the position layout of the internal control switch 44, air pressure detection sensor 41, speaker 45, display screen 42, battery 43 and other electronic components on the PCB board 4, thereby avoiding excessive space occupation by the internal electronic components and ensuring the realization of the miniaturization of the structure of the breathing trainer.

[0034] Specifically, one end of the second PCB board unit 4b close to the bottom surface 1c extends to the bottom surface 1c, the charging port 6 is electrically connected to the second PCB board 4, the control switch 44, the speaker 45, and the air pressure detection sensor 41 are all provided on the first PCB board unit 4a, and the display screen 42 and the battery 43 are provided on the second PCB board unit 4b

[0035] Furthermore, the second PCB board unit 4b is arranged on the center line of the housing 1. In this way, the lower half space inside the housing 1 can be divided into two spaces of the same size. The display screen 42 is arranged on one side of the second PCB board unit 4b facing the front surface 1a, and the battery 43 is arranged on one side of the second PCB board unit 4b facing the back surface 1b. In this way, the occupation of the internal space of the housing 1 by the battery 43 and the display screen 42 can be minimized, and the structure of the breathing trainer can be miniaturized.

[0036] Further, the first PCB board unit 4a is disposed inside the housing 1 and near the front surface 1a, that is, the second PCB board unit 4b can divide the upper half of the housing 1 into a large space and a small space in the direction from the front surface 1a to the back surface 1b. The air chamber 32 of the air chamber member 3 and the speaker 45 are both located on the side of the first PCB board unit 4a facing the back surface 1b. The air pressure detection sensor 41 is disposed on the side of the first PCB board unit 4a facing the back surface 1b of the housing 1 and extends into the detection hole 322, and the control switch 44 is disposed on the side of the first PCB board unit 4a facing the front surface 1a. In this way, it is convenient to reasonably install the air chamber 32 and the speaker 45 that occupy a large volume and the control switch 44 that occupies a small volume, and to realize the reasonable layout of the upper half space inside the housing 1.

[0037] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
