[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention arranges the cooperation of structures such as the plug-in block, the first anti-slip pattern, and the filter screen so that the device can insert the plug-in block into the interior of the monitor body. The filter screen is located between the airflow and monitoring components such as the pressure sensor and the source low-frequency second-order filter inside the monitor body, so that the air blown out by the user can be filtered through the filter screen to prevent excessive impurities in the gas from affecting the final monitoring results. The user can use the friction provided by the first anti-slip pattern to more conveniently plug in and replace the plug-in block, thereby achieving the purpose of filtering the exhaled air when the user uses the device.

[0020] The present invention cooperates with structures such as a mouthpiece, an air guide groove, and a positioning block so that when the device needs to monitor respiration, one side of the protective cover can be pried open so that the buckle of the protective cover is separated from the connection with the top of the monitor body, and then the protective cover is rotated to leak out of the air inlet, and the mouthpiece is inserted into the air inlet. The positioning block can fix the position of the mouthpiece by its own shape, and the sealing ring can prevent the gas from escaping when the user uses the device to monitor respiration. The user patient stands up and takes a deep breath, then puts the mouthpiece into the mouth, wraps the mouthpiece tightly with the lips, and exhales forcefully and quickly so that the gas enters the inside of the device through the air guide groove and contacts the pressure sensor to monitor the data, thereby achieving a more hygienic user when using the device and preventing impurities from falling into the inside of the device and affecting the device when the device is idle.

[0033] like Figures 1 to 9As shown, the outer wall of the air inlet 5 is provided with a drainage mechanism 8, a wrist strap 9 is fixed to the bottom end of the monitor body 1, the outer wall of the monitor body 1 is provided with a second anti-slip pattern 10, the protective cover 2 is rotatably connected to the top of the monitor body 1, and the second anti-slip pattern 10 is provided with a plurality of groups of equally spaced side walls of the monitor body 1, and the second anti-slip patterns 10 are symmetrically distributed about the central axis of the monitor body 1.

[0034] The above scheme is adopted: the monitor body 1 is started by pressing the switch button 3, and the protective cover 2 lights up at this time. After the user blows, the airflow passes through the pressure sensor inside the monitor body 1. The sensor converts the airflow pressure into an electrical signal, and processes it through the circuit, and finally obtains parameters such as the peak expiratory flow rate. At this time, the surface of the data display screen 4 displays the parameters. These parameters can reflect the patient's respiratory function status and provide important diagnostic basis for doctors.

[0035] like Figures 1 to 9 As shown, the disassembly and assembly mechanism 7 includes a pressing rod 701, a first return spring 702 and an extrusion block 703. The pressing rod 701 is installed on the inner wall of the monitor body 1. The bottom end of the pressing rod 701 is fixed with a first return spring 702. The first return spring 702 is fixed at the bottom end inside the monitor body 1. The first return spring 702 is used to squeeze the pressing rod 701 and keep it moving upward.

The extrusion blocks 703 are provided with two groups symmetrically distributed about the central axis of the pressing rod 701, the inner wall of the monitor body 1 is slidably connected to the limit block 704, the inner wall of the plug block 601 is slidably connected to the limit rod 705, and the side wall of the limit rod 705 is fixed with a second reset spring 706, the limit block 704 is provided with several groups slidably connected to the inner wall of the monitor body 1, the limit rod 705 is provided with several groups slidably connected to the inner wall of the plug block 601, and the second reset spring 706 is used to squeeze the limit rod 705 and keep it moving inward.

[0037] The above scheme is adopted: when the plug block 601 needs to be replaced, the pressing rod 701 is pressed, so that the position of the extrusion block 703 moves downward and contacts the limit block 704. When the extrusion block 703 contacts the limit block 704 through its own inclined surface, it can push the limit block 704 to move outward, so that the limit block 704 pushes the limit rod 705 out of the connection groove with the monitor body 1. At this time, the plug block 601 can be pulled out to replace the plug block 601. When installing the plug block 601, keep pressing When the rod 701 is in the pressed state, the insert block 601 is inserted so that the limit rod 705 is aligned with the limit block 704 and then released. The first return spring 702 presses the pressing rod 701 upward, thereby driving the extrusion block 703 to break away from the contact with the limit block 704, so that the limit block 704 will not be squeezed from above. At this time, the second return spring 706 can squeeze the limit rod 705, so that the limit rod 705 contacts the limit block 704 and pushes itself and the limit block 704 into the fixing groove of the outer wall of the monitor body 1 for fixation.

[0038] like Figures 1 to 9 As shown, the filtering mechanism 6 includes an insert block 601, a first anti-slip pattern 602 and a filter screen 603. The insert block 601 is slidably connected to the inner wall of the monitor body 1. The surface of the insert block 601 is provided with a first anti-slip pattern 602. The filter screen 603 is installed on the top of the insert block 601. The first anti-slip pattern 602 is symmetrically distributed about the central axis of the insert block 601. The surface of the filter screen 603 is provided with a plurality of groups of holes, and the holes are located on the central axis of the filter screen 603 and are evenly spaced.

[0039] The above scheme is adopted: by inserting the plug 601 into the interior of the monitor body 1, the filter 603 is positioned between the airflow and the monitoring components such as the pressure sensor, source low-frequency second-order filter, etc. inside the monitor body 1, so that the air blown out by the user can be filtered through the filter 603 to prevent excessive impurities in the gas from affecting the final monitoring results. The user can use the friction provided by the first anti-slip pattern 602 to more conveniently plug in and replace the plug 601.

[0040] like Figures 1 to 9 As shown, the drainage mechanism 8 includes a mouthpiece 801, an air guide groove 802, a positioning block 803 and a sealing ring 804. The mouthpiece 801 is installed on the inner wall of the air inlet 5. The top of the mouthpiece 801 is provided with an air guide groove 802. The outer wall of the mouthpiece 801 is fixed with a positioning block 803. The outer wall of the mouthpiece 801 is installed with a sealing ring 804. The mouthpiece 801 and the air inlet 5 are slidably connected. The bottom end of the air guide groove 802 is connected to the inner cavity of the monitor body 1. Two groups of positioning blocks 803 are provided, and the positioning blocks 803 are symmetrically distributed about the central axis of the mouthpiece 801.

[0041] The above scheme is adopted: by prying open one side of the protective cover 2, the buckle of the protective cover 2 is separated from the connection with the top of the monitor body 1, and then the protective cover 2 is rotated to leak out of the air inlet 5, and the mouthpiece 801 is inserted into the air inlet 5. The positioning block 803 can fix the position of the mouthpiece 801 by its own shape, and the sealing ring 804 can prevent the gas from escaping when the user uses the device to monitor the breathing. The user patient stands up and takes a deep breath, then puts the mouthpiece 801 into the mouth, wraps the mouthpiece 801 tightly with the lips, and exhales forcefully and quickly to allow the gas to enter the device through the air guide groove 802 and contact the pressure sensor to monitor the data, so as to achieve a more hygienic user when using the device.

[0042] The working principle and use process of the present invention are as follows: the monitor body 1 is started by pressing the switch button 3, at which time the protective cover 2 lights up, and after the user blows air, the airflow passes through the pressure sensor inside the monitor body 1, and the sensor converts the airflow pressure into an electrical signal, and processes it through a circuit, and finally obtains parameters such as the peak expiratory flow rate. At this time, the surface of the data display screen 4 displays the parameters, and these parameters can reflect the patient's respiratory function status and provide important diagnostic basis for doctors. By inserting the plug 601 into the interior of the monitor body 1, the position of the filter 603 is located between the airflow and the pressure sensor inside the monitor body 1, the source low-frequency second-order filter and other monitoring groups The air blown by the user can be filtered through the filter screen 603 to prevent the air from containing too many impurities and affecting the final monitoring result. The user can more conveniently plug and unplug the plug block 601 through the friction provided by the first anti-slip pattern 602. When the plug block 601 needs to be replaced, the pressing rod 701 is pressed so that the position of the extrusion block 703 moves downward and contacts the limit block 704. When the extrusion block 703 contacts the limit block 704 through its own inclined surface, it can push the limit block 704 to move outward, so that the limit block 704 pushes the limit rod 705 to withdraw from the connection groove with the monitor body 1. The first reset spring 702 presses the pressing rod 701 upward, thereby driving the squeezing block 703 to break away from the contact with the limit block 704, so that the limit block 704 will not be squeezed from above. At this time, the second reset spring 706 can squeeze the limit rod 705, so that the limit rod 705 contacts the limit block 704 and pushes itself and the limit block 704 into the fixing groove of the outer wall of the monitor body 1 for fixing. By prying open one side of the protective cover 2, The buckle of the protective cover 2 is separated from the connection with the top of the monitor body 1, and then the protective cover 2 is rotated to leak out of the air inlet 5, and the mouthpiece 801 is inserted into the air inlet 5. The positioning block 803 can fix the position of the mouthpiece 801 by its own shape, and the sealing ring 804 can prevent the gas from escaping when the user uses the device to monitor the breathing. The user patient stands up and takes a deep breath, then puts the mouthpiece 801 into the mouth, wraps the mouthpiece 801 tightly with the lips, and exhales forcefully and quickly to allow the gas to enter the device through the air guide groove 802 and contact the pressure sensor to monitor the data, so as to achieve a more hygienic use of the device by the user.
