The basic working principle of the percussion device of the vibration percussion sputum excretion machine is as follows: the flexible axle 9 transmits the rotary motion of the main machine output of the vibration percussion sputum excretion machine to the rotating shaft 1, the eccentric shaft 12, the adjusting sleeve 4 and the percussion head 7 are sequentially sleeved from inside to outside and rotate together, and the percussion head 7 rotates and moves up and down simultaneously due to the fact that the percussion head 7 has eccentricity relative to the main rotating shaft 11, so that the human body can be knocked. The amplitude of the rapping head 7 is twice the total eccentricity C. The purpose of the meshing of the inner ring gear 411 with the outer ring gear 121 is to transmit the rotary motion of the eccentric shaft 12 to the adjustment sleeve 4. The fastener 5 serves to limit the axial movement of the adjustment sleeve 4.
The invention can change the total eccentricity C by rotating the adjusting sleeve 4 and changing the relative position of the adjusting sleeve 4 and the eccentric shaft 12, thereby adjusting the amplitude of the percussion device.
The total eccentricity C is adjusted as follows: firstly, fixing the rotating shaft 1, loosening the fastening piece 5, and moving the adjusting sleeve 4 forwards to enable the inner gear ring 411 to leave the outer gear ring 121; then the adjusting sleeve 4 is rotated to adjust the total eccentricity C, after the adjustment is proper, the adjusting sleeve 4 is moved inwards to enable the inner gear ring 411 to be meshed with the outer gear ring 121, and then the fastener 5 is screwed down.
According to the standard YY/T1665-2019 of the medical industry of the people's republic of China, the maximum amplitude of the knocking head 7 is generally not more than 7mm, and when the knocking head is used for children or people with weak bodies, the amplitude of the knocking head 7 is preferably 3mm. Therefore, the first eccentricity A is preferably 2.5mm, the second eccentricity B is preferably 1mm, the adjustment range of the total eccentricity C is 1.5-3.5 mm, and the amplitude adjustment range of the rapping head 7 is preferably 3-7 mm.
The total eccentricity C is the distance between the excircle axis of the adjusting sleeve main body 41 and the axis of the main rotating shaft 11. As shown in fig. 5, when the included angle between the first eccentricity a and the second eccentricity B is 180 °, the total eccentricity C = the first eccentricity a + the second eccentricity B, that is, the total eccentricity C is 3.5mm, and the amplitude of the impact head 7 is 7mm. As shown in fig. 6, when the included angle between the first eccentricity a and the second eccentricity B is 0 °, the total eccentricity C = the first eccentricity a to the second eccentricity B, that is, the total eccentricity C is 1.5mm, and the amplitude of the impact head 7 is 3mm. As shown in fig. 7, when the angle between the first eccentricity a and the second eccentricity B is 78.5 °, the total eccentricity C is 2.5mm, and the amplitude of the rapping head 7 is 5mm.
As previously described, the purpose of the engagement of the inner ring gear 411 with the outer ring gear 121 is to transmit the rotational movement of the eccentric shaft 12 to the adjustment sleeve 4. As shown in fig. 3 and 4, the outer ring gear 121 has a plurality of convex teeth, and the inner ring gear 411 has a plurality of concave tooth spaces, and the teeth correspond to the tooth spaces one by one and are embedded in the tooth spaces.
Theoretically, the adjusting sleeve 4 and the eccentric shaft 12 can have a relative position equal to the number of teeth and gullets, so that the amplitude of the rapping head 7 of the present invention can be many.
During the amplitude adjustment, the rotation of the shaft 1 should be avoided when loosening and tightening the fastening member 5 and rotating the adjustment sleeve 4. The main rotating shaft 11 is located in the hand-held sleeve 2, and the eccentric shaft 12 is located in the outer gear ring 121, so if no mechanism is provided to prevent the main rotating shaft 11 from rotating, the rotation prevention of the main rotating shaft 11 is inconvenient.
The preferred vibration percussion sputum excretion machine comprises a rotating shaft locking structure 8, wherein the rotating shaft locking structure 8 comprises a locking column 81, a button 82, a limiting sheet 84 and a first spring 83; the locking column 81 is arranged along the radial direction of the main rotating shaft 11, the locking column 81 penetrates through the handheld sleeve 2, the button 82 is connected to the outer end of the locking column 81, the first spring 83 is sleeved on the locking column 81 and located between the button 82 and the handheld sleeve 2, the first spring 83 outwards supports the button 82, the limiting piece 84 is located in the handheld sleeve 2, and the limiting piece 84 is connected with the locking column 81 and abuts against the handheld sleeve 2; the main rotating shaft 11 is provided with an inserting hole 111 corresponding to the position of the locking column 81; when the button 82 is pressed, the locking post 81 can be inserted into the insertion hole 111.
Thus, the push button 82 is not pressed, the first spring 83 supports the push button 82 outward, the locking post 81 is not inserted into the insertion hole 111, and the rotation shaft 1 is rotatable. The button 82 is pressed, the locking column 81 moves inwards and is inserted into the insertion hole 111, the rotation of the rotating shaft 1 can be limited, and the operation is very convenient. The pivot locking formation 8 is preferably located relatively close to the front end of the glove 2.
The invention can be further configured as follows: the vibrating percussion sputum excretion machine comprises a second spring 6, a spring ring groove 122 is arranged on the eccentric shaft 12, and the second spring 6 is arranged in the spring ring groove 122 and supports the adjusting sleeve bottom plate 42 forwards. Therefore, when the fastening piece 5 is loosened, the second spring 6 can push the adjusting sleeve 4 to move forwards, so that the inner gear ring 411 is separated from the outer gear ring 121, and the amplitude adjusting operation is further facilitated. Tightening the fastener 5 compresses the second spring 6 without affecting the rearward movement of the adjustment sleeve 4.
In order to know the specific value of the amplitude, as shown in fig. 5 to 7, the adjusting sleeve bottom plate 42 is provided with an observation hole 421, the front end surface of the eccentric shaft 12 is provided with an amplitude number 123, and the amplitude number 123 aligned with the observation hole 421 is the amplitude of the percussion head 7. Thus, the amplitude of the tapping head 7 can be directly observed through the observation hole 421.
Further, the present invention is preferably as follows: the adjusting sleeve bottom plate 42 is spaced from the front end surface of the adjusting sleeve main body 41, and the fastening piece 5 does not exceed the front end surface of the adjusting sleeve main body 41. The fastener 5 is hidden, so that the situation that the fastener 5 is rotated to hit a human body can be avoided.
The rapping head 7 should not be rigid, but the rapping head 7 may be made of a somewhat flexible material, such as rubber.
