[0028] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0029] Example 1

[0030] See also Figure 1-10 In the embodiment, an ear canal foreign body cleaning device is provided, comprising: an outer tube 1, one end of the outer tube 1 is fixedly connected to a connector 11, one end of the outer tube 1 is provided with a sleeve 12, one end of the sleeve 12 is fixedly connected to two spindle-shaped springs 13, the outer side of the outer tube 1 is provided with anti-slip grooves 14, one end of the sleeve 12 is provided with a through hole 15, a suction component, the suction component is arranged outside the outer tube 1, and is used to suck small foreign bodies in the ear canal, and a disassembly and assembly component is arranged inside the outer tube 1, and is used to install and fix the sleeve 12.

[0031] When cleaning the ear canal, the sleeve 12 is sleeved onto the connector 11 of the outer tube 1, and the inner wall of the ear canal is cleaned by the spring 13 of the spindle-shaped structure. The anti-slip pattern 14 is convenient for medical staff to hold, and the through hole 15 is connected to the suction hole 23. The suction component can clean up small fragments of foreign matter, and can scrape off foreign matter stuck to the inner wall of the ear canal, and then suck away the scraped foreign matter. With the adjustable suction force, the foreign matter can be directly sucked out to improve the practicality of the device. Then, the required tools can be quickly replaced by disassembling and assembling the components. The space occupancy is small, it is easy to store, and the cost is low. When cleaning the ear canal, when the tool type needs to be frequently changed, there is no need to find and replace the entire tool, thereby improving work efficiency. The replaceable tool head can meet the needs of cleaning different foreign matter.

[0032] Example 2

[0033] On the basis of Example 1, the suction assembly includes: a connecting tube 2 fixedly connected to the outside of the outer tube 1, a connecting port 21 connected to one end of the connecting tube 2, an air inlet hole 22 opened at the other end of the connecting tube 2, a suction hole 23 opened inside the outer tube 1, a connecting hole 24 opened on one side of the suction hole 23, and the connecting hole 24 is conductive with the inside of the connecting tube 2.

[0034] When cleaning tiny foreign objects in the ear canal, one end of the spring 13 is inserted deep into the ear canal. The spindle-shaped spring 13 can hang down tiny foreign objects on the ear canal wall. The suction tube of the external suction device is connected to the connecting port 21, and then the external suction device is started. Gas is sucked in from one end of the air inlet 22 and flows rapidly inside the connecting tube 2. Since the air flow rate inside the connecting tube 2 is greater than the air flow rate inside the suction hole 23, the gas inside the suction hole 23 will enter the connecting tube 2 along the connecting hole 24 and be sucked away, thereby generating suction at the through hole 15 at one end of the outer tube 1, thereby sucking away tiny foreign objects. The spindle-shaped spring 13 is used to clean up tiny foreign objects on the inner wall of the ear canal and then suck them away, thereby cleaning. At the same time, the ear canal dirt can also be cleaned. At the same time, the sleeve 12 is removed and the outer tube 1 is used directly to suck out foreign objects in the ear canal, thereby increasing the practicality of the device.

[0035] Among them, the mounting plate 25 outside the outer tube 1 is close to one end of the air inlet 22, and the mounting plate 25 is internally threadedly connected with a threaded screw 26, one end of the threaded screw 26 is fixedly connected to a knob 27, and the other end of the knob 27 is fixedly connected to a blocking block 28.

[0036] When the suction force needs to be adjusted, the knob 27 is turned to drive the threaded screw 26 to rotate and screw with the mounting plate 25. The force generated by the screwing of the threads drives the threaded screw 26 to move, and one end of the threaded screw 26 drives the blocking block 28 to move into the air inlet 22. Since the air inlet 22 and the blocking block 28 are both arranged in a trapezoidal structure, when the blocking block 28 continues to move into the air inlet 22, the aperture of the air inlet 22 is reduced. At this time, the air inlet inside the air inlet 22 is reduced and the air inlet The amount of gas also becomes smaller, and a large amount of gas will be sucked in from the through hole 15 and the suction hole 23, thereby increasing the suction force of the suction hole 23 and the through hole 15. When the aperture of the air inlet hole 22 becomes larger, the corresponding suction force of the suction hole 23 and the through hole 15 becomes smaller. By controlling the rotation direction of the control knob 27, the blocking block 28 is controlled to move left and right, thereby adjusting the aperture size of the air inlet hole 22, thereby adjusting the suction force change of the suction hole 23 and the through hole 15, so as to adapt to the cleaning of different foreign matter.

[0037] One end of the outer tube 1 away from the connector 11 is threadedly connected to a threaded block 29 , one end of the threaded block 29 is fixedly connected to a fixing rod 210 , one end of the fixing rod 210 extends into the suction hole 23 and is fixedly connected to a sealing block 211 .

[0038] When the suction hole 23 is blocked by foreign matter, the threaded block 29 is unscrewed and pulled out, and the threaded block 29 drives the fixing rod 210 to move, and the fixing rod 210 pulls the sealing block 211 out of the suction hole 23, so that the two ends of the suction hole 23 are connected to each other. At this time, a slender rod is used to be inserted into the suction hole 23 to push out the foreign matter blocked inside the suction hole 23.

[0039] Example 3

[0040] On the basis of Example 1, the disassembly and assembly components include: a sliding cavity 3 opened inside the outer tube 1, an inner sleeve 31 slidably connected inside the sliding cavity 3, two symmetrical placement grooves 32 opened on one side of the sliding cavity 3, balls 33 are slidably connected inside the two placement grooves 32, an arc groove 34 opened on the outside of the inner sleeve 31 near one end of the connector 11, a fixing groove 35 opened on the inner wall of the sleeve 12, two symmetrically arranged limiting grooves 36 opened on the sliding cavity 3 away from the side of the placement groove 32, sliding rods 37 are slidably connected inside the limiting grooves 36, one end of the two sliding rods 37 is connected to the inner sleeve 31, and the other ends of the two sliding rods 37 are fixedly connected to the sliding sleeve 38, an installation groove 39 is opened near the middle position of the sliding cavity 3, a pushing ring 310 is fixedly connected to the outside of the inner sleeve 31, the pushing ring 310 is located inside the installation groove 39, and a spring 311 is connected between the pushing ring 310 and the installation groove 39.

[0041] In the process of cleaning foreign objects in the ear canal, different types of foreign objects may be encountered. Therefore, in order to meet the needs of cleaning foreign objects, different tools are used for operation, such as retractors, ear spoons and other tools. When changing tools, the sliding sleeve 38 is pulled to the left. When the sliding sleeve 38 is pulled, the sliding rod 37 is driven to move inside the limiting groove 36 until it hits the inner wall on the left side of the limiting groove 36. The sliding rod 37 drives the inner sleeve 31 to move inside the sliding cavity 3. When the inner sleeve 31 moves, the external pushing ring 310 simultaneously moves to the left to squeeze the spring 311. The spring 311 is squeezed and contracts to store energy. The inner sleeve 31 moves to the left so that the arc groove 34 moves to the bottom of the two placement grooves 32. Then the sleeve 12 is pulled off to the left, and the sleeve 1 When moving to the left, the ball 33 is pushed toward the center, so that the ball 33 is pushed into the two placement grooves 32, thereby releasing the fixation of the sleeve 12, selecting the required tool head, sleeve the sleeve 12 at one end of the tool onto the connector 11, and pushing the sleeve 12 to the right to the rightmost end, then loosening the sliding sleeve 38, the spring 311 loses its binding and releases its elasticity, pushing the push ring 310 to move to the right, and the push ring 310 drives the inner sleeve 31 to move to the right, and the ball 33, under the action of the arc groove 34, pushes the ball 33 to move from the inside of the placement groove 32 to the outside on both sides, and the ball 33 is stuck in the fixing groove 35 of the sleeve 12, thereby fixing the sleeve 12, so that the tool can be quickly replaced and the cleaning efficiency is improved.
