[0026] The filter 15 is a filtering device connecting the subject and the handheld part 13, and is used to assist the patient in checking and diagnosing lung function. When in use, the exhaled gas of the subject passes through the filter 15, filtering out the saliva during the blowing, thereby effectively avoiding cross infection; the one-time use can also reduce the loss of the equipment and improve the working efficiency of lung function testing.

[0027] The plug-in plate 33 can drive the filter 15 to move, and enable the filter 15 to be plugged and assembled with the mouthpiece 16 , and then the filter 15 is assembled on the handheld part 13 .

[0028] The mouthpiece 16 has a connecting tube 161 . The mouthpiece 16 is made of a silicone material, and the connecting tube 161 is made of plastic. The connecting tube 161 is used for plugging and fixing with the filter 15 .

[0029] The filter 15 is evenly arranged in the filter cavity 21 along the front-to-back direction, and the filter 15 is placed vertically, and the axis of the slot 151 is distributed along the left-to-right direction; the mouthpiece 16 is evenly arranged in the mouthpiece cavity 22 along the front-to-back direction, and the mouthpiece 16 is placed vertically, and the axis of the connecting tube 161 is distributed along the left-to-right direction.

[0033] When the protrusion 311 is located in the driving groove 63, the plug-in plate 33 is directly opposite to the slot 151 in the filter chamber 21. The eccentric wheel 35 cooperates with the eccentric abutment plate 331, and at this time, the screw 6 rotates, the protrusion 311 slides along the driving groove 63, the screw connecting plate 31 does not move, and the screw 6 drives the eccentric wheel 35 to rotate, so that the eccentric wheel 35 drives the plug-in plate 33 to plug into the slot 151.

[0034] An eccentric column 351 capable of abutting against the eccentric abutment plate 331 is disposed at an eccentric position on the eccentric wheel 35 ; the eccentric wheel 35 and the screw rod 6 are connected through a synchronous belt 36 .

[0036] The mounting cavity 23 is longitudinally slidably connected with a reset rod 74 driven by the hand-held portion 13; a reset spring is arranged between the reset rod 74 and the mounting cavity 23; the lower end of the reset rod 74 is provided with a reset inclined surface 741 which can abut against the slider 332 and thus force the plug-in board 33 to separate from the slot 151; when the clamping mechanism 3 makes the combined filter 15 and the mouthpiece 16 located below the hand-held portion 13, the reset rod 74 is opposite to the slider 332, and the hand-held portion 13 is installed on the main body 11 at this time, the hand-held portion 13 will press down the reset rod 74, so that the reset inclined surface 741 abuts against the slider 332 and forces the slider 332 to move, thereby separating the elastic protrusion 333 from the limiting protrusion 322, and the tension spring 34 drives the plug-in board 33 to reset, and the plug-in board 33 is separated from the slot 151, and the hand-held portion 13 and the filter 15 are plugged together.

[0037] A limiting plate 5 is arranged in the installation cavity 23; a steering gear 324 is coaxially arranged on the movable frame 32; a rack 52 which is distributed along the left and right directions and can mesh with the steering gear 324 is arranged on the limiting plate 5; the rack 52 drives the steering gear 324 to rotate 180°; limiting grooves 51 are respectively arranged on the left and right sides of the rack 52 on the limiting plate 5; a rotation limiting groove 323 which is slidably connected with the limiting groove 51 to limit the rotation of the movable frame 32 is arranged on the movable frame 32.

[0038] When the limiting groove 323 is located in the limiting groove 51, the movable frame 32 drives the plug-in board 33 to be located vertically; when the rotating gear 324 moves to the middle of the rack 52, the rotating gear 324 rotates 90°, and then the movable frame 32 drives the plug-in board 33 to move to the horizontal, and the filter 15 on the plug-in board 33 moves to the horizontal synchronously. At this time, when the hand-held part 13 is placed on the host 11, the hand-held part 13 is opposite to the filter 15, which is convenient for the filter 15 to be assembled on the hand-held part 13.

[0039] A feeding mechanism 4 is provided in the replenishing bin 2; the feeding mechanism 4 includes a mouthpiece push plate 46 slidably connected in the mouthpiece cavity 22, a filter push plate 42 sliding in the filter cavity 21, and a filter disc 41 and a mouthpiece disc 45 rotating in the mounting cavity 23; a filter pull rope 43 is wound around the filter disc 41; one end of the filter pull rope 43 is connected to the filter push plate 42; a mouthpiece pull rope 47 is wound around the mouthpiece disc 45; one end of the mouthpiece pull rope 47 is connected to the mouthpiece push plate 46.

[0040] A mouthpiece gear 451 is coaxially arranged on the mouthpiece plate 45; a filter gear 411 is coaxially arranged on the filter plate 41; the feeding mechanism 4 also includes a rotatable synchronization rod 44; a first gear 441 and a second gear 442 are coaxially arranged on the synchronization rod 44; the first gear 441 is meshed with the filter gear 411; the second gear 442 is meshed with the mouthpiece gear 451; the transmission ratio between the filter plate 41 and the mouthpiece plate 45 is equal to the diameter ratio between the filter 15 and the mouthpiece 16.

[0041] When the filter disc 41 rotates, the filter push plate 42 is driven to move through the filter pull rope 43, and the filter push plate 42 pushes the filter 15 to feed. At the same time, the filter disc 41 is transmitted through the synchronization rod 44, so that the mouthpiece disc 45 rotates, and the mouthpiece push plate 46 pushes the mouthpiece 16 to feed. Since the movement speeds of the filter push plate 42 and the mouthpiece push plate 46 are different, the diameters of the filter 15 and the mouthpiece 16 are adapted, so that the new filter 15 and the mouthpiece 16 arrive at the assembly position at the same time, which is convenient for the clamping mechanism 3 to work.

[0042] A motor 71 is fixedly connected in the installation cavity 23; a motor gear 72 is arranged on the output shaft of the motor 71; a screw gear 61 capable of meshing with the motor gear 72 is coaxially arranged on the screw 6; the motor gear 72 can be transmission-connected to the screw 6 and the mouthpiece plate 45.

[0043] A sliding frame 73 is slidably connected in the installation cavity 23; the sliding frame 73 and the motor gear 72 move axially synchronously; a conical surface 131 for driving the sliding frame 73 to move is provided on the hand-held part 13; a sliding spring for resetting the sliding frame 73 is provided between the sliding frame 73 and the installation cavity 23; when the hand-held part 13 is not installed on the main unit 11, the sliding frame 73 enables the motor gear 72 to be transmission-connected with the screw 6; when the hand-held part 13 is installed on the main unit 11, the conical surface 131 drives the sliding frame 73 to move until the motor gear 72 is transmission-connected with the mouthpiece plate 45, and the motor gear 72 is meshed with the mouthpiece gear 451.

[0044] The handheld portion 13 is provided with an insertion port 132 for plugging with the filter 15 .

[0045] In the initial state, the handheld part 13 is mounted on the host 11, and a filter 15 is connected to the plug interface 132 of the handheld part 13, and a mouthpiece 16 is connected to the filter 15. Under the action of the conical surface 131 of the handheld part 13, the reset inclined surface 741 on the reset rod 74 drives the plug-in board 33 to separate from the slot 151 on the filter 15, and the sliding frame 73 makes the motor gear 72 mesh with the mouthpiece gear 451. The new mouthpiece 16 and filter 15 are pushed by the mouthpiece push plate 46 and the filter push plate 42 respectively to move to face the clamping mechanism 3.

[0046] During operation, the patient picks up the handheld part 13 so that the handheld part 13 is separated from the main unit 11 . The patient holds the mouthpiece 16 and blows or inhales into the handheld part 13 .

[0047] At the same time, as the handheld portion 13 leaves the main body 11 , the reset rod 74 is reset upward, and the sliding frame 73 is reset, so that the sliding frame 73 drives the motor gear 72 to mesh with the screw gear 61 .

[0048] Then the motor 71 works, and the motor gear 72 drives the screw 6 to rotate. The screw 6 drives the screw connecting portion 31 to move toward the filter chamber 21. In this process, the rack 52 is meshed with the steering gear 324, so that the moving frame 32 rotates to a vertical position, and then the rotation limiting groove 323 on the moving frame 32 moves into the limiting groove 51, and the moving frame 32 no longer rotates.

[0049] As the screw 6 rotates, the protrusion 311 on the screw connection part 31 moves along the thread groove 62 into the driving groove 63. At this time, the plug-in board 33 is opposite to the slot 15, and the eccentric column 351 on the eccentric wheel 35 is opposite to the eccentric plate 331. The screw 6 continues to rotate, and the screw connection part 31 no longer moves axially. At this time, the screw 6 drives the eccentric wheel 35 to rotate, and the eccentric column 351 pushes the eccentric plate 331, so that the plug-in board 33 moves toward the slot 151. Finally, the plug-in board 33 is inserted into the slot 151, and the plug-in board 33 is relatively fixed to the filter 15. At the same time, the tension spring 34 is extended, and the elastic protrusion 333 passes over the limiting protrusion 322. At this time, the limiting protrusion 322 prevents the elastic protrusion 333 from moving in the opposite direction, thereby preventing the plug-in board 33 from resetting.

[0050] Then the motor 71 drives the screw 6 to rotate in the opposite direction, and the screw 6 drives the clamping mechanism 3 to move toward the mouthpiece cavity 22. Finally, the moving frame 32 moves into the limiting groove 51 close to the mouthpiece cavity 22. The filter 15 on the plug-in board 33 is plugged into the connecting pipe 161 on the mouthpiece 16, and the mouthpiece 16 is installed on the filter 15.

[0051] Then the motor 71 drives the screw 6 to rotate, and the screw 6 drives the screw connection part 31 to move toward the rack 52, and finally the screw connection part 51 moves to the middle position of the rack 52. The rack 52 drives the steering gear 324 to rotate 90 degrees, and the mobile frame 32 rotates to the horizontal, and then the filter and the mouthpiece also rotate to the horizontal, waiting to be assembled with the handheld part 13.

[0052] After the patient examination is completed, the mouthpiece 15 and the filter 15 on the handheld part 13 are removed and discarded. Then the handheld part 13 is installed on the main unit 11. As the handheld part 13 is installed in the main unit 11, the handheld part 13 is assembled with the horizontal filter 15 and the mouthpiece 16 in the main unit 11. At the same time, the conical surface 131 on the handheld part 13 drives the reset rod 74 and the sliding frame 73 to move. The reset rod 74 moves downward, and the reset inclined surface 741 abuts against the slider 332, so that the elastic protrusion 333 breaks through the limit of the limit protrusion 322, and then the tension spring 34 drives the plug-in board 33 to reset, and the plug-in board 33 is separated from the filter 15, and then the new filter 15 and the mouthpiece 16 are assembled on the handheld part 13, waiting for the next use.

[0053] At the same time, the sliding frame 73 drives the motor gear 72 to mesh with the mouthpiece gear 451. The motor 71 works, and the mouthpiece plate 45 and the filter plate 41 rotate. The filter pull rope 43 is wound on the filter plate 41, and then the filter push plate 42 pushes each filter 15 to feed, so that the next filter 15 is facing the clamping mechanism 3. The mouthpiece pull rope 47 is wound on the mouthpiece plate 45, and then the mouthpiece push plate 46 pushes the mouthpiece 16 to feed, so that the next mouthpiece 16 is facing the clamping mechanism 3. At this point, the host 11 returns to the initial state.
