Description

Technical Field

[0001] The utility model relates to the technical field of sanitary products, in particular to an ear canal washing head. Background Art

[0002] An ear canal irrigator is a sanitary product for flushing the ear canal, and is mainly used to flush secretions and other earwax in the external auditory canal. Some ear canal irrigators in the prior art generally place the irrigating head close to the ear canal opening, and then drip the irrigating liquid into the ear canal from the ear canal opening. This type of ear canal irrigator is not convenient for alignment with the ear canal opening, and it is easy to cause the irrigating liquid to spill on the user's face or other positions, causing trouble to the user. And the irrigating liquid enters the ear canal from the ear canal opening, which is also easy to cause discomfort to the user and reduce the comfort of use. In addition, if the cleaning liquid cannot enter the ear canal smoothly, the effect of ear canal flushing will also be reduced. If the ear canal irrigator is directly extended into the ear canal, the insertion depth of the ear canal irrigating head cannot be controlled, which is easy to cause damage to the human ear. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide an ear canal flushing head, which can facilitate users to flush the ear canal, improve the comfort of use and the flushing effect, and avoid damage to the human ear.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is as follows: an ear canal flushing head, comprising a liquid inlet end, a main body, a stopper and a liquid outlet end connected in sequence, the liquid inlet end, the main body and the liquid outlet end are respectively provided with a liquid inlet, a liquid flow channel and a liquid outlet, the liquid inlet, the liquid flow channel and the liquid outlet are connected in sequence; the outer diameter of the liquid outlet end is smaller than the inner diameter of the ear canal opening, and the outer diameter of the stopper is larger than the inner diameter of the ear canal opening.

[0005] Compared with the prior art, the beneficial effect of the utility model is that the ear canal flushing head is provided with a stopper near the liquid outlet, and the outer diameter of the liquid outlet is smaller than the inner diameter of the ear canal opening, and the outer diameter of the stopper is larger than the outer diameter of the ear canal opening. When in use, the liquid outlet is inserted into the ear canal. Since the outer diameter of the stopper is larger, it will be stopped outside the ear canal opening, thereby preventing the liquid outlet from being inserted too deeply and preventing the human ear from being damaged. After the liquid outlet is inserted into the ear canal, flushing liquid can be added from the liquid inlet. After the flushing liquid flows through the liquid flow channel, it flows out from the liquid outlet into the ear canal to achieve cleaning of the ear canal. The ear canal flushing head can directly insert the liquid outlet into the ear canal, and can better add flushing liquid into the ear canal, which can not only facilitate the user to flush the ear canal and avoid the flushing liquid from spilling everywhere, but also improve the user's comfort and flushing effect.

[0006] In the above-mentioned ear canal flushing head, the stopper is an annular stopper.

[0007] In the above-mentioned ear canal flushing head, the outer diameter of the liquid outlet end gradually decreases in the direction away from the stop portion.

[0008] The above-mentioned ear canal flushing head has the liquid inlet end in a funnel shape.

[0009] In the above-mentioned ear canal flushing head, the cross section of the liquid inlet end is elliptical.

[0010] In the above-mentioned ear canal flushing head, the liquid inlet end is connected to the main body part at an angle.

[0011] In the above-mentioned ear canal flushing head, an arc-shaped transition section is connected between the liquid inlet end and the main body.

[0012] In the above-mentioned ear canal flushing head, the inner diameters of the liquid inlet, the liquid flow channel and the liquid outlet decrease successively.

[0013] In the above-mentioned ear canal flushing head, the liquid inlet end, the main body, the stopper and the liquid outlet end are integrally formed.

[0019] Description of the accompanying drawings: 100 liquid inlet end, 110 liquid inlet port, 200 arc-shaped transition section, 300 main body, 310 liquid flow channel, 400 stopper, 500 liquid outlet end, 510 liquid outlet port. DETAILED DESCRIPTION

[0020] The embodiments of the present invention are described in detail below. Figures 1 to 4An embodiment of the utility model provides an ear canal flushing head, comprising a liquid inlet end 100, a main body 300, a stopper 400 and a liquid outlet end 500 connected in sequence, wherein a liquid inlet 110, a liquid flow channel 310 and a liquid outlet 510 are sequentially provided inside the liquid inlet end 100, the main body 300 and the liquid outlet end 500, and the liquid inlet 110, the liquid flow channel 310 and the liquid outlet 510 are sequentially connected; the outer diameter of the liquid outlet end 500 is smaller than the inner diameter of the ear canal opening, and the outer diameter of the stopper 400 is larger than the inner diameter of the ear canal opening.

[0021] The ear canal flushing head is provided with a stopper 400 near the liquid outlet 500, and the outer diameter of the liquid outlet 500 is smaller than the inner diameter of the ear canal opening, and the outer diameter of the stopper 400 is larger than the outer diameter of the ear canal opening. When in use, the liquid outlet 500 is inserted into the ear canal. Since the outer diameter of the stopper 400 is larger, it will be stopped outside the ear canal opening, thereby preventing the liquid outlet 500 from being inserted too deeply and preventing the human ear from being hurt. After the liquid outlet 500 is inserted into the ear canal, a flushing liquid can be added from the liquid inlet 110. After the flushing liquid flows through the liquid flow channel 310, it flows out from the liquid outlet 510 into the ear canal to achieve cleaning of the ear canal. The ear canal flushing head can directly insert the liquid outlet 500 into the ear canal, and can better add the flushing liquid into the ear canal, which can not only facilitate the user to flush the ear canal and avoid the flushing liquid from spilling everywhere, but also improve the user's comfort and flushing effect.

[0022] Further, refer to Figure 2 The stopper 400 is an annular stopper so as to be attached to the auricle and better stopped outside the ear canal opening to prevent the liquid outlet 500 from being inserted too deeply, and to increase the contact area between the stopper 400 and the auricle, which can further reduce discomfort and improve the comfort of use. Furthermore, the outer diameter of the liquid outlet 500 gradually decreases in the direction away from the stopper 400, which can not only provide a guide for the insertion of the liquid outlet 500, but also further reduce the risk of ear canal damage.

[0023] Further, refer to Figure 1 and Figure 4 The liquid inlet end 100 is funnel-shaped, and the liquid inlet 110 is also funnel-shaped. When in use, the opening of the flushing liquid reservoir is opened, and the opening of the flushing liquid reservoir is extended into the liquid inlet 110 of the ear canal flushing head, and the flushing liquid reservoir is squeezed to add the flushing liquid into the liquid inlet 110. The liquid inlet end 100 and the liquid inlet 110 are funnel-shaped, so that a certain temporary storage space can be provided for the flushing liquid to prevent the flushing liquid from overflowing from the liquid inlet 110. Furthermore, the cross section of the liquid inlet end 100 is elliptical, so as to facilitate the positioning of the opening of the flushing liquid reservoir and better squeeze the flushing liquid into the liquid inlet 110.

[0024] Furthermore, the liquid inlet end 100 is connected to the main body 300 at an angle, so that the liquid inlet 110 and the liquid flow channel 310 are set at an angle. When the flushing liquid reservoir is squeezed, the flushing liquid will not rush directly into the ear canal, thereby avoiding damage to the ear canal. In addition, when the flushing liquid flows from the liquid inlet 110 to the liquid flow channel 310, it needs to pass through a bend, thereby providing a buffer for the flow of the flushing liquid, further avoiding the flushing liquid from being poured into the ear canal with too much pressure, thereby further reducing the risk of ear canal damage. Specifically, referring to Figure 3 and Figure 4 An arc-shaped transition section 200 is connected between the liquid inlet end 100 and the main body 300 to form a bend here to provide a buffer. The transition connection method can also facilitate the processing and molding of the flushing head. Furthermore, the liquid inlet end 100, the main body 300, the stopper 400 and the liquid outlet end 500 are integrally formed to facilitate mass production. In order to further increase the comfort of use and reduce the risk of ear canal damage, the inner diameters of the liquid inlet 110, the liquid flow channel 310 and the liquid outlet 510 are reduced in sequence, so as to further provide a buffer for the flow of the flushing liquid, so that the flushing liquid can flow into the ear canal at a slower speed and a smaller diameter water column.
