There are also two sets of friction blocks 9 fixedly arranged on the peripheral side wall of the dial 7, the friction blocks 9 are arranged in the gap 23, the two sets of friction blocks 9 are respectively located on both sides of the annular groove 8, and each group of friction blocks 9 is set to be several , A number of friction blocks 9 in each group are evenly distributed along the circumferential direction of the dial 7. A reinforcing block 10 is fixedly connected to both sides of the dial 7, and the reinforcing block 10 is in the shape of a disc. A reinforcing block 10 facing the reduced diameter opening 18 is coaxially fixed with a screw 13 and a matching sleeve on the screw 13 is provided with a second A movable seat 12, the first movable seat 12 is integrally connected with two sliders 11, the two sliders 11 are matched with the two sliding grooves 31 one by one, and the first movable seat 12 is also fixedly connected with a plurality of connecting rods 14 The length of the second movable seat 16 and the connecting rod 14 is greater than or equal to the length of the screw 13. The end of the screw 13 facing the reduced diameter opening 18 is also fixedly connected with a limit disk 15, and the diameter of the limit disk 15 is larger than the diameter of the screw 13.
[0029] The second movable seat 16 of one linear output device is fixedly connected with the first soft plug 17, and the second movable seat 16 of the other linear output device is fixedly connected with the second soft plug 21. The fixed connection between the second movable seat 16 and the first soft plug 17 or the second soft plug 21 may be to provide a clamping block on the second movable seat 16 and a block on the first soft plug 17 or the second soft plug 21 The card slot matched with the card block not only realizes a fixed connection, but also can replace the first soft plug 17 or the second soft plug 21. The first soft plug 17 has a cylindrical shape, and the end of the first soft plug 17 facing the reduced diameter opening 18 has a hemispherical shape. The second soft plug 21 is in the shape of a tower. The long side of the section of the second soft plug 21 forms a saw-tooth-like structure in the direction from the tip to the tail end. Each saw tooth is inclined to the tail end, and the bends are set in a circle. Angle, the tip of the tower shape is hemispherical to form a hemispherical head 22. The diameter of the first soft plug 17 and the diameter of the second soft plug 21 are both larger than the inner diameter of the reduced diameter opening 18. Both the first soft plug 17 and the second soft plug 21 are made of memory foam, preferably PU foam. The first soft plug 17 and its housing 5 and the corresponding linear output device together form a cerumen softening mechanism, and the second soft plug 21, its housing 5 and the corresponding linear output device together form a cerumen removal mechanism.
[0030] A part of the housing 5 near the reduced diameter opening 18 where the first soft plug 17 is located is also provided with a through hole 19, and a communicating head 20 is fixedly arranged in the through hole 19, and the communicating head 20 includes a fixed connection with the inner wall of the through hole 19 The duct base 30 and the duct 29 passing through the duct base 30.
[0031] It also includes a liquid addition bottle. The liquid addition bottle includes a screw-connected bottle bottom 25 and a bottle body 26. The bottle body 26 is also integrally connected with a conical bottle mouth 27. The inside of the bottle mouth 27 is fixed with a one-way valve 28, and The conduction direction of the valve 28 is from the bottle mouth 27 to the bottle bottom 25.
[0032] The method of use of the present invention is as follows.
[0033] Step 1: Use the cerumen softening mechanism to soften the cerumen in the external auditory canal, thereby facilitating the removal of the cerumen.
[0034] First, add a solution for softening the cerumen into the liquid addition bottle, which can be physiological saline. The specific method is to separate the bottom 25 and the body 26 by rotating the bottom 25, then add the solution to the bottom 25, and then re The bottle bottom 25 and the bottle body 26 are installed. Because the bottle mouth 27 is provided with a one-way valve 28, the solution will not flow out of the liquid adding bottle. Secondly, the catheter 29 is inserted into the bottle mouth 27, and the catheter 29 conducts the one-way valve 28 so that the solution can flow along the catheter 29 into the housing 5 where the first soft plug 17 is located. After that, the dial 7 of the linear output device connected to the first soft plug 17 is moved to drive the screw 13 to rotate. Through the cooperation of the screw 13 and the first movable seat 12, the first movable seat 12 is driven to the reduced diameter opening 18. The first movable seat 12 drives the second movable seat 16 and the first soft plug 17 to move in the direction of the diameter-reducing opening 18 through the connecting rod 14. The first soft plug 17 drips through the conduit 29 during the movement. On the first soft stopper 17, the first soft stopper 17 is infiltrated, but because only one side of the first soft stopper 17 is infiltrated, the solution is not evenly distributed in the first soft stopper 17. As the soft plug 17 continues to move, the first soft plug 17 starts to protrude from the reduced diameter opening 18. Because the diameter of the reduced diameter opening 18 is smaller than the diameter of the first soft plug 17, the first soft plug 17 will be compressed. The gas in the first soft plug 17 is squeezed out, and the solution with less content can be retained and evenly distributed in the first soft plug 17. Because it is made of memory foam, the first soft plug 17 is removed from the shell After the body 5 is extended, it continues to maintain the compressed state. At this time, the first soft plug 17 is extended into the external auditory canal. As air continues to enter, the first soft plug 17 gradually expands and returns to its original size, and fits with the external auditory canal. The solution in the first soft plug 17 will infiltrate the cerumen, thereby realizing the softening of the cerumen.
[0035] Step two, use the cerumen removal structure to remove the cerumen from the external auditory meatus.
[0036] Similar to step 1, the second soft plug 21 is driven to protrude from the housing 1 by rotating the dial 7 of the linear output device connected to the second soft plug 21. When the second soft plug 21 passes through the reducing buckle 18 After being compressed, the protruding part of the second soft plug 21 is inserted into the external auditory canal, and then the second soft plug 21 inhales air to expand and restore. The expanded second soft plug 21 fits on the external auditory canal, and then pulls the first soft plug outward. Two soft plugs 21, the tower-shaped outer wall of the second soft plug 21 can continuously peel the softened cerumen from the external auditory canal, and the cerumen is temporarily stored in the recessed part of the outer wall, as the second soft plug 21 is pulled , Can completely remove the cerumen in the external auditory canal and take it out of the external auditory canal.
[0037] The invention adopts the method of first softening and then clearing to remove the cerumen, so as to clean the external ear canal. The adhesive force between the softened cerumen and the skin of the external ear canal is reduced, and it is easier to remove, and the removal process will not cause damage to the external ear canal. . At the same time, the present invention uses the first soft plug 17 and the second soft plug 21 made of memory foam as tools for softening and taking out the cerumen, which will not cause damage to the skin of the external auditory canal when directly contacting the skin of the external auditory canal, and the first soft plug 17 and the second soft plug 21 can fully fit with the external auditory canal during the expansion process, so as to ensure that the softening of the cerumen and the removal of the cerumen can be very thorough, and there will be no residue.
[0038] In summary, the present invention can completely remove the cerumen of the external auditory canal without causing damage to the skin of the external auditory canal, and is particularly suitable for infants with delicate skin.
[0039] In other embodiments of the present invention, because the memory foam material is not suitable for cleaning, it needs to be replaced after a period of use. Therefore, the housing 5 can be divided into two parts evenly along the axial direction, and the two parts are detachable by inserting blocks and slots. Connection, thereby facilitating the replacement of the second soft plug 17 and the second soft plug 21.
