Technical Field

[0001] The utility model belongs to the technical field of ear suction nozzles, in particular to a suction nozzle for ear suction nozzles. Background Art

[0002] When earwax (cerumen) appears, you can use an ear suction device to deal with it; an ear suction device, also known as an ear aspirator or earwax remover, is a tool used to remove earwax (cerumen) in the ear canal; the working principle of the ear suction device is mainly based on negative pressure suction, which creates a local vacuum environment to suck out earwax. When using the ear suction device, gently insert the ear suction head into the patient's external auditory canal, being careful not to go too deep to avoid damaging the eardrum; then open the ear suction device and use the suction head to suck the earwax out of the ear canal.

[0003] Because the depth of the external auditory canal of adults is about 2.5 to 3.5 cm, in order to protect the eardrum, the length of the suction tip inserted into the external auditory canal should not exceed about 2 cm; because the depth of the external auditory canal of children is about 1 to 1.5 cm, in order to protect the eardrum, the length of the suction tip inserted into the external auditory canal should not exceed about 1 cm; if it exceeds, the risk of injuring the eardrum will increase significantly.

[0004] Therefore, although the ear suction nozzle in the prior art is convenient for sucking out earwax during use, it is difficult to judge the depth of the nozzle inserted into the ear canal. Once improperly operated, the eardrum may be easily injured. Utility Model Content

[0005] The utility model aims to provide a suction head for an ear suction device, which solves the problem that it is inconvenient to judge the insertion depth of the ear canal during the use of the ear suction device, thereby easily causing damage to the eardrum.

[0006] The suction head for the ear suction device comprises a horizontally arranged suction tube; the left end of the suction tube is connected to a connector which is in communication with the suction tube and is used to be connected to the ear suction device; a sleeve is sleeved on the suction tube, the sleeve is made of elastic material and fits with the outer wall of the suction tube; a limiting ring is sleeved on the sleeve for limiting the suction tube to the outside of the ear canal.

[0007] Furthermore, the straw is provided with scale lines on its outer side wall along its length direction.

[0008] Furthermore, the straw is made of silicone material.

[0009] Furthermore, the ring is made of silicone material.

[0010] Furthermore, the length of the straw is 3-4 cm.

[0011] Furthermore, the right end of the straw is a closed structure, and a suction hole for sucking earwax is provided on the outer side wall of the right end of the straw.

[0020] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0021] Example 1

[0022] The ear suction nozzle of the present embodiment is as follows: Figure 1 , Figure 3 and Figure 5 As shown, it includes a horizontally arranged straw 1; the left end of the straw 1 is connected to a connector 3 which is in communication with the straw 1 and is used to connect to the ear suction device; the connector 3 is connected to the ear suction device in a conventional manner, and the structure of the connector 3 is like a bottle cap, and the inner side wall of the connector 3 is provided with an internal thread, and the upper side of the ear suction device is provided with an external thread for threading with the internal thread, so the connector 3 can be installed on the ear suction device in a threaded manner, such as Figure 5The position in the figure is a schematic diagram of the structure in which the connector 3 is installed on the ear suction device; because the connector 3 is connected to the suction tube 1, the connector 3 drives the suction tube 1 to be installed on the ear suction device; when in use, the right end of the suction tube 1 is inserted into the ear canal of the user, and then the ear suction device is turned on. The ear suction device generates negative pressure suction, and the earwax can be sucked into the ear suction device through the suction tube 1 and the connector 3;

[0023] like Figure 1 and Figure 2 As shown, the straw 1 is covered with a collar 6, which is made of elastic material and fits with the outer wall of the straw 1; when the collar 6 is covered on the straw 1, it is clamped on the straw 1 by the friction force generated by its elastic force, just like a rubber band can be tied on the hair; therefore, in the absence of external force, the collar 6 can be stably covered on the straw 1, and when the collar 6 is pulled to move, it can be moved to different positions on the straw 1 because of its elastic force;

[0024] like Figure 1 and Figure 2As shown, a limiting ring 2 is mounted on the ring 6 for limiting it to the outside of the ear canal; the limiting ring 2 and the ring 6 are fixedly connected; because the straw 1 can be inserted into the ear canal of the user, the ring 6 can be driven to be inserted into the ear canal of the user. At this time, in order to prevent the ring 6 from moving into the ear canal of the user, the outer diameter of the limiting ring 2 is designed according to the size of the ear hole, so that the size of the ear hole is smaller than the outer diameter of the limiting ring 2. The size of the normal ear hole is not fixed, and the diameter is usually about 0.5-1cm, which varies from person to person; therefore, the outer diameter of the limiting ring 2 can be designed to be in the range of 1.1-1.5cm, so that the limiting ring 2 cannot enter the ear hole from the position of the ear hole, because the limiting ring 2 and the ring 6 are fixedly connected together, so the purpose of limiting the position of the limiting ring 2 outside the ear canal is achieved; at this time, because the ring 6 can move to different positions on the straw 1, and the position of the ring 6 can remain stable without the action of external force, the limiting ring 2 can be driven to move to the straw. 1; therefore, the cooperation between the limiting ring 2 and the sleeve ring 6 can limit the depth of the straw 1 inserted into the ear canal, because the ear canal depths of adults and children are different, the length of the adult inserted into the ear canal should not exceed about 2cm, and the length of the child inserted into the ear canal should not exceed about 1cm; when used for adults, the limiting ring 2 and the sleeve ring 6 are moved to a position 2cm away from the right end of the straw 1, so that the straw 1 can only be inserted into the user's ear canal 2cm; when used for children, the limiting ring 2 and the sleeve ring 6 are moved to a position 1cm away from the right end of the straw 1, so that the straw 1 can only be inserted into the user's ear canal 1cm; therefore, by adjusting the position of the limiting ring 2 and the sleeve ring 6, the depth of the straw 1 inserted into the ear canal is limited, avoiding the problem of the straw 1 being inserted too deeply and causing damage to the eardrum, so that the design can clarify the depth of the ear canal inserted by the straw 1 for people of different age groups, and improve the safety of the ear suction device during use;

[0025] like Figure 1 As shown, the straw 1 is provided with scale lines 4 on its outer side wall along its length direction, and the starting point of the scale lines 4 is Figure 1 The right end of the middle straw 1 ends at Figure 1 The left end of the middle straw 1; through the design of the scale line 4, the position of the limit ring 2 and the collar 6 can be quickly adjusted to determine the distance between the limit ring 2 and the collar 6 and the right end of the straw 1, which increases the convenience during use;

[0026] The length of the straw 1 is 3-4 cm. In a specific implementation process, the length of the straw 1 can be selected to be 3 cm, 4 cm or any value between 3-4 cm. By setting this range, the straw 1 can be used more stably. If the length of the straw 1 is less than 3 cm, when the distance of insertion into the ear canal is 2 cm, and the straw 1 needs to be turned over during use, the length of the straw 1 is too short, which will lead to the problem of inconvenience in operating the ear suction device. If the length of the straw 1 is greater than 4 cm, it will lead to waste of resources and increase production costs.

[0027] like Figure 1 and Figure 4 As shown, the right end of the straw 1 is a closed structure, and a suction hole 5 for sucking earwax is provided on the outer side wall of the right end of the straw 1. When in use, because earwax generally adheres to the side wall of the ear canal of the user, by providing the suction hole 5 on the outer side wall of the straw 1 instead of providing the suction hole 5 at the end of the straw 1, it is convenient to suck the earwax on the side wall of the ear canal from the suction hole 5, and it is also possible to protect the eardrum and avoid the suction force generated by the ear suction device from being adsorbed in the direction of the eardrum.

[0028] The straw 1 is made of silicone material; the ring 6 is made of silicone material; silicone has many advantages, such as elasticity, softness and flexibility, not easy to deform, non-toxic and tasteless, and good wear resistance, so the products made of it can withstand a certain external friction without damage or cracking, and the products made of it have a longer life than other materials; therefore, when the straw 1 is inserted into the ear canal of the user, it can also provide more comfort to the user; therefore, the ring 6 can be more stably put on the straw 1;

[0029] During specific use: first, insert the straw 1 connected to the ear suction device into the patient's ear canal. If it is used for adults, move the limiting ring 2 and the sleeve ring 6 to a position 2 cm away from the right end of the straw 1, so that the straw 1 can only be inserted 2 cm into the user's ear canal; if it is used for children, move the limiting ring 2 and the sleeve ring 6 to a position 1 cm away from the right end of the straw 1, so that the straw 1 can only be inserted 1 cm into the user's ear canal; therefore, during the insertion of the straw 1, its insertion depth can be clearly determined, thereby improving the safety of the straw 1 during use and protecting the user's eardrum as much as possible.
