[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, an ear canal suction device for ENT care includes a box body 1, a box door is fixedly installed on the front left part of the box body 1, an adjustment and disassembly component 2 is fixedly installed on the left side of the box body, a fixing component 3 is fixedly installed on the upper left part of the box body 1, a suction component 4 is fixedly installed on the middle part of the right side of the box body 1, and a handle is fixedly installed on the lower right part of the box body 1.

[0028] By adjusting the disassembly component 2, the rotation angle of the adjustment tube 25 can be adjusted, so that the dirt at various angles in the patient's ear can be cleaned. At the same time, the adjustment tube 25 and the inner tube 22 can be quickly disassembled and cleaned without affecting the subsequent working state of the suction device. The fixing component 3 can facilitate the disassembly and fixation of the filter plate 38, and the dirt in the ear canal can be attracted to the filter plate 38 for easy cleaning and collection. The suction component 4 can use the adjustment tube 25 to attract earwax on the outer wall of the ear canal.

[0029] like Figure 5 As shown, the adjustment and disassembly component 2 includes a fixed frame, the right side of the fixed frame is fixedly installed on the left side of the box body 1, and a suction hood 21 is fixedly installed on the middle left side of the box body 1, and the suction hood 21 is located in the inner cavity of the fixed frame. The inner wall left part of the suction hood 21 is movably sleeved with an inner tube 22, and the front and rear left parts of the fixed frame are slidably connected with an insertion rod 23 that penetrates the front and rear parts of the fixed frame, and the front and rear parts of the outer wall of the inner tube 22 are provided with slots, and the ends of the two insertion rods 23 that are close to each other penetrate the front and rear positions of the left part of the outer wall of the suction hood 21 and are inserted into the inner walls of the two slots, and the sides of the outer walls of the two insertion rods 23 that are away from each other are movably sleeved with springs 24, and the ends of the two springs 24 that are close to each other are fixedly connected to the left parts of the front and rear sides of the fixed frame, and the ends of the two springs 24 that are away from each other are fixedly connected to the ends of the two insertion rods 23 that are away from each other.

[0030] By pulling out the two plug rods 23, the two plug rods 23 stretch the two springs 24 and disengage the plug-in relationship with the two slots, so that the inner tube 22 can be quickly removed for cleaning. When the inner tube 22 needs to be installed, the two plug rods 23 can be re-plugged into the two slots through the restoring force of the two springs 24.

[0031] like Figure 6 As shown, the right part of the outer wall of the inner tube 22 is rotatably connected with an adjusting tube 25, and the right part of the outer wall of the adjusting tube 25 is fixedly sleeved with a gear 26. The rear positions of the left parts of the upper and lower ends of the fixed frame are slidably connected with sliding rods 27 that pass through the upper and lower parts of the fixed frame. Racks 28 are fixedly installed at the opposite ends of the two sliding rods 27, and the front side of the rack 28 is meshed with the outer surface of the gear 26.

[0032] The movement of the two slide bars 27 can drive the rack 28 to move, so that the gear 26 can drive the adjustment tube 25 to rotate to different angles by meshing with the rack 28, thereby achieving cleaning work at different positions of the patient's ear canal.

[0033] like Figure 2 and Figure 6 As shown, three linearly arranged magnets 29 are fixedly installed on the rear side of the rack 28, a slide groove 210 is opened on the left rear side of the fixed frame, a slide plate 211 is slidably connected to the inner wall of the slide groove 210, an iron plate 212 is fixedly installed on the front side of the slide plate 211, and the iron plate 212 is located directly behind the three magnets 29.

[0034] By pushing the slide plate 211 , the three magnets 29 and the iron plate 212 are attracted to each other and merged together, and then the slide plate 211 can be pushed to slide in the slide groove 210 to drive the two slide bars 27 to move.

[0035] like Figure 7 As shown, the fixing assembly 3 includes a mounting bracket 31, the lower end of the mounting bracket 31 is fixedly mounted on the upper left portion of the box body 1, the upper end of the mounting bracket 31 is rotatably connected to an adjusting screw 32 that passes through the top of the mounting bracket 31, the lower end of the adjusting screw 32 is rotatably connected to the upper left portion of the box body 1, and the outer wall of the adjusting screw 32 is threadedly connected to a sliding sleeve 33.

[0036] By rotating the adjusting screw 32 , the sliding sleeve 33 moves up and down by being threadedly connected with the adjusting screw 32 .

[0037] like Figure 7As shown, the left and right parts of the upper end of the mounting frame 31 are slidably connected with fixed rods 34 that pass through the top of the box body 1, and the outer walls of the two fixed rods 34 are fixedly installed with connecting sleeves 35. The opposite sides of the outer walls of the two connecting sleeves 35 are fixedly connected to the left and right parts of the outer wall of the sliding sleeve 33. The tops of the outer walls of the two fixed rods 34 are movably sleeved with limiting springs 36, and the lower ends of the two limiting springs 36 are fixedly connected to the left and right parts of the upper end of the mounting frame 31. The ends of the two limiting springs 36 away from the mounting frame 31 are fixedly connected to the upper ends of the two fixed rods 34.

[0038] The sliding sleeve 33 moves the two connecting sleeves 35 and the fixing rod 34 , and the movement of the fixing rod 34 drives the limit spring 36 to be acted upon by force. The restoring force of the two limit springs 36 makes the resetting of the two fixing rods 34 easier.

[0039] like Figure 7 As shown, slide rails 37 are fixedly installed at the left and right positions of the upper and lower parts of the inner wall of the box body 1, and filter plates 38 are slidably connected on the opposite sides of the four adjacent slide rails 37. The filter apertures on the left sides of the two filter plates 38 are opened in a decreasing trend from left to right. Fixed grooves are opened in the middle of the upper ends of the two filter plates 38, and the lower ends of the two fixing rods 34 pass through the tops of the two upper slide rails 37 and are plugged into the inner walls of the two fixed grooves.

[0040] The two filter plates 38 can be fixed by the plug-in relationship between the two fixing rods 34 and the two fixing grooves, so that the filter plates 38 will not be displaced when the suction device is working, and the removal of the two filter plates 38 is also faster and more convenient. The decreasing aperture setting on the two filter plates 38 can prevent dirt from concentrating on one filter plate 38 and causing blockage.

[0041] like Figure 4 As shown, the suction component 4 includes a vent cylinder 41, the left side of the vent cylinder 41 is fixedly installed on the right side of the box body 1, a fixing plate 42 is fixedly installed on the inner wall of the vent cylinder 41, a motor 43 is fixedly installed on the middle part of the right side of the fixing plate 42, the outer wall of the output end of the motor 43 passes through the right part of the fixing plate 42 and is fixedly installed with a plurality of blades 44 arranged in a ring form, and a plurality of through grooves are opened on the right side of the fixing plate 42.

[0042] The output end of the motor 43 can drive a plurality of blades 44 to rotate, so that the air in the box is discharged to the outside through the through slot, thereby sucking out the dirt on the patient's ear canal.

[0043] The working principle of the utility model is as follows: the staff extends the adjustment tube 25 into the patient's ear canal by holding the handle, starts the motor 43, and the output end of the motor 43 drives the blade 44 to rotate, so that the earwax in the ear canal is sucked into the box body 1 through the inner tube 22 and the suction cover 21 due to the suction force, and is contaminated on the filter plate 38. The staff pushes the slide plate 211, so that the iron plate 212 and the three magnets 29 attract each other and merge together, and then moves the slide plate 211, so that the slide plate 211 slides on the inner wall of the slide groove 210 and drives the rack 28 to move through the two slide bars 27, and the gear 26 drives the adjustment tube 25 to rotate by meshing with the rack 28, so that the adjustment tube 25 can change the direction of sucking earwax. After the suction device finishes working, the staff pulls out the two rods 23, so that the two rods 23 stretch the springs 24 and disengage the plug-in relationship with the two slots, so that the adjustment tube 25 and the inner tube 22 can be removed at the same time for cleaning. After the cleaning is completed, pull the rods 23 to insert the inner tube 22 into the suction cover 21. After letting go, the restoring force of the two springs 24 can reset the two rods 23, thereby fixing the inner tube 22.

[0044] When the two filter plates 38 need to be cleaned, the adjusting screw 32 is rotated, and the sliding sleeve 33 drives the two connecting sleeves 35 and the fixing rod 34 to move upward through the threaded connection with the adjusting screw 32, so that the two fixing rods 34 are disengaged from the plug-in relationship with the two fixing grooves. The staff opens the box door and slides the two filter plates 38 out from between the four adjacent slide rails 37 for cleaning. After cleaning, the two filter plates 38 are slid back into the inner cavity of the box body 1, and the adjusting screw 32 is rotated to move the sliding sleeve 33 to reset, and the two fixing rods 34 fix the two filter plates again.
