Background

Along with the improvement of people's standard of living, the electric ear cleaner has appeared on the market in order to improve original earpick spoon, replaces artifical external auditory canal to clean through electronic mode. For example, the applicant previously filed a chinese patent with publication number CN109077847A, which discloses a multifunctional electric ear pick-up device, comprising a housing and a metal suction tube, wherein a through hole for earwax to enter the metal suction tube is formed on the circumferential surface of the front end of the metal suction tube, a dirt storage chamber is arranged on the housing, the rear end of the metal suction tube is connected to a hollow shaft, the hollow shaft is communicated with the dirt storage chamber, an air suction device for sucking earwax into the dirt storage chamber through the metal suction tube is correspondingly arranged in the housing, the hollow shaft and the housing are sealed and form a rotating fit, and a driving device for driving the hollow shaft to rotate is further connected to the hollow shaft.

The ear picking device of the prior application can correspondingly drive the hollow shaft and the metal suction pipe inserted on the hollow shaft to rotate together through the driving device so as to clean the external auditory meatus of the human body in an electric mode. However, since the external auditory canal of a human body is fragile, if the metal straw is excessively inserted into the external auditory canal during use, the external auditory canal is damaged, or the ear is damaged and the hearing is affected due to excessive exertion. Meanwhile, if the earpick cannot enter the external auditory canal sufficiently, the cleaning effect is not good. Thus, in summary: how to improve the cleaning effect of earwax as much as possible while avoiding damage to the external auditory canal is a problem to be solved urgently by those skilled in the art.

SUMMERY OF THE UTILITY MODEL

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

As shown in fig. 1, 2 and 3, an ear picking device comprises a hollow shaft 1 and a driving device (not shown in the drawings) for driving the hollow shaft 1 to rotate, wherein an ear picking rod 2 which can be linked with the hollow shaft 1 is inserted in the hollow shaft 1, an elastic member 3 and a moving rod 4 which can push and extrude the elastic member 3 are arranged in the ear picking rod 2, and one end of the moving rod 4 which penetrates out of the ear picking rod 2 is provided with a cleaning head 5 which can scrape the ear; when the elastic element 3 is extruded, one end of the movable rod 4 in the ear picking rod 2 is in insertion fit with the ear picking rod 2 to form linkage.

When in use, the ear cleaner is inserted into the external auditory canal by a user. At this time, the movable rod 4 firstly extends into the external auditory canal until the cleaning head 5 abuts against the external auditory canal, and then one end of the movable rod 4 is urged to slide into the ear picking rod 2. One end of the rod to be moved 4 slides into abutment with the elastic member 3 and transmits the abutment force received from the external auditory meatus to the elastic member 3, thereby pressing the elastic member 3, so that the elastic member 3 is elastically deformed. In this state, the force exceeding the external auditory meatus of the human body is not transmitted to the hollow shaft 1 but is eliminated by the elastic member 3. Draw the ear ware and can correspond drive hollow shaft 1 and cartridge and draw ear pole 2 on hollow shaft 1 and rotate together through drive arrangement, because when elastic component 3 received the extrusion, move the pole in drawing the one end in ear pole 2 and draw ear pole 2 grafting cooperation in order to form the linkage, and then can drive the carriage release lever 4 in step and rotate to make and be located 5 pairs of ears of cleaning head of 4 one ends of carriage release lever and strike off, thereby scrape the earwax down, clear up effectually.

Furthermore, a limiting groove 6 or a limiting block 7 is arranged at one end of the moving rod 4 in the ear picking rod 2, and the limiting block 7 or the limiting groove 6 is arranged in the ear picking rod 2; when the elastic piece 3 is extruded, the limiting groove 6 is matched with the limiting block 7 in an inserting way.

Furthermore, the end of the hollow shaft 1 is provided with a rotating member 8 which can be matched with a driving device, and the rotating member 8 is a driven gear. The driving device comprises a motor and a driving gear, wherein the driving gear is arranged on an output shaft of the motor and is meshed and linked with the driven gear. The driving device is disclosed in the patent reference, and will not be described in detail herein.

Further, be provided with in the hollow shaft 1 and be used for the location to draw ear pole 2 the silica gel cover 9, this silica gel cover 9 is located hollow shaft 1 and draws between ear pole 2 and correspond the suit on drawing ear pole 2. Through the arrangement, the hollow shaft 1 and the ear picking rods 2 are linked through the silica gel sleeve 9, so that frictional resistance generated between the hollow shaft 1 and the ear picking rods 2 drives the ear picking rods 2 to synchronously rotate; meanwhile, the ear picking rod 2 is very convenient to insert or pull out from the hollow shaft 1, so that the ear picking rod 2 can be detached and cleaned without detaching other parts.

Furthermore, draw ear ware can arrange a casing in, and this casing with draw and be connected through bearing 10 location between the ear ware. Specifically, a step 11 is arranged on the hollow shaft 1, and a bearing 10 is sleeved on the step 11 of the hollow shaft 1. The bearing 10 is provided to allow relative rotation of the housing and the earpick inside the housing.

Further, a cap 12 is connected to one side of the silica gel sleeve 9 of the hollow shaft 1 through a thread, and a hole 13 for the ear rod 2 to pass through is formed in the axis of the cap 12. By arranging the cap 12, the silica gel sleeve 9 can be effectively prevented from being synchronously taken out in the process of inserting and pulling the ear-picking rod 2, and the silica gel sleeve 9 is limited; meanwhile, the cap 12 can limit the bearing 10, so that the bearing 10 is limited on the step 11.

Furthermore, the front end of the ear picking rod 2 is further covered with a flexible sleeve 14, and a plurality of convex ribs 15 are distributed on the outer circumferential surface of the flexible sleeve 14. Through the arrangement, the ear picking rod 2 can rotate, and the convex ribs 15 can scrape off the ear hooks in the auditory canals, so that the cleaning effect is better; simultaneously, protruding muscle 15 can carry out the butt to the cleaning head 5 of 4 one ends of carriage release lever, is avoiding the embedding of cleaning head 5 to draw in the ear pole 2 and convenient to use person discerns fast and draws ear pole 2 and carriage release lever 4.

Further, in the present embodiment, the elastic member 3 is preferably a spring.

Further, the cleaning head 5 is made of a soft material, and is preferably cotton in this embodiment.
