Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to a nose pad capable of storing volatile liquid and slowly releasing the volatile liquid. Background Art

[0002] Glasses are widely used, including myopia glasses, sunglasses, decorative non-functional glasses, etc. Myopia glasses are generally used to correct vision, sunglasses are generally used to protect eyes in the sun, and some glasses are purely for decorative effects. Due to the widespread use of glasses, there are more and more requirements for glasses, but the functions of existing glasses are relatively simple when used.

[0003] To this end, the Chinese utility model with the announcement number CN209514225U proposes "a kind of safe liquid storage glasses", including a frame and a lens arranged on the frame, a nose pad and a glasses leg hinged on the frame, the glasses leg including a leg rod, an end seat and a volatilization cover, the leg rod is provided with a liquid storage chamber, one end of the end seat is inserted into the liquid storage chamber from the end of the leg rod, and the other end is connected to the frame, the liquid storage chamber is provided with a volatilization hole, and the volatilization cover is provided on the volatilization hole. By arranging the liquid storage chamber on the glasses leg, and sealing the liquid storage chamber by using the end seat and the volatilization cover, the smell will eventually be dissipated from the end seat position, so that the glasses can store perfume or essential oil, which can keep the fragrance or refreshment for a long time, and the perfume or essential oil is released slowly and evenly.

[0004] In order to make the hole position of volatile gas closer to the user's nasal cavity, the Chinese utility model with announcement number CN215375994U proposes "a kind of eyeglass stent", which is symmetrically arranged on both sides of the bridge of the glasses. The eyeglass stent includes a stent body, a connecting part arranged on the stent body for connecting the stent body and the glasses, and also includes a cavity arranged inside the stent body, a through hole arranged on the stent body connecting the cavity and the outside of the stent body, and a volatile material is installed in the cavity.

[0005] When the volatile material inside the above-mentioned glasses leg with a liquid storage chamber or glasses support with a cavity evaporates, the material can be added by pulling out the additional plug. However, due to the large volume difference between the glasses support and the glasses leg: if the plug set on the glasses support is too large, it is not convenient for the glasses support to support the glasses frame, and after the plug is too large, it will compress the storage volume of the volatile material too much; if the plug set on the glasses support is too small, it will be inconvenient to repeatedly pull out and repeatedly insert the plug, and a plug that is too small will be more easily damaged when pulling out and inserting. It is necessary to improve the structure of repeatedly adding volatile materials to this type of glasses support. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-4 A nose pad 10 capable of storing volatile liquid and slowly releasing the volatile liquid comprises a nose pad body 101, wherein a liquid storage cavity 103 is arranged inside the nose pad body 101, and the nose pad body 101 is constructed to have a certain thickness and be hollow inside.

[0032] A slow-release hole 104 communicating with the liquid storage cavity 103 is formed on the outer side of the nose pad body 101 , and the volatile liquid in the liquid storage cavity 103 is slowly volatilized and released through the slow-release hole 104 .

[0033] The nose pad body 101 is an elastic body structure or a soft body structure. When the liquid storage cavity 103 is squeezed by applying force to the nose pad body 101, the liquid storage cavity 103 is correspondingly formed into a variable volume liquid storage cavity.

[0034] The nose pad body 101 may be made of soft plastic, such as polyurethane (PU), for example, by additive manufacturing, or by molding, injection molding, and then bonding.

[0035] When adding volatile liquid, the volume of the liquid storage cavity 103 is correspondingly flattened to become smaller by manually squeezing the nose pad body 101, thereby expelling the air in the liquid storage cavity 103; then the slow-release hole 104 is moved to the volatile liquid to be added, and the squeezing of the nose pad body 101 is released to restore it to the shape before squeezing, at which time the volume of the liquid storage cavity 103 is correspondingly restored to become larger, and in the process of the volume of the liquid storage cavity 103 increasing, negative pressure is formed at the orifice of the slow-release hole 104, so that the volatile liquid to be added is sucked into the liquid storage cavity 103, and the addition of the volatile liquid is completed. The process of adding volatile liquid is more convenient, and the volume of the liquid storage cavity 103 is not affected.

[0036] The volatile liquid can be a perfume that adds fragrance, or an aromatherapy liquid with special effects, and so on.

[0037] Preferably, a protrusion 106 is formed on the inner wall of the liquid storage chamber 103, and the protrusion 106 extends toward the direction close to the sustained-release hole 104. By selecting the number of protrusions 106, the surface area of ​​the volatile liquid in the liquid storage chamber 103 can be controlled, thereby controlling the overall volatilization rate.

[0038] There are multiple protrusions 106 , which are formed on the inner wall of the liquid storage cavity 103 . Strip-shaped grooves are formed between adjacent protrusions 106 .

[0039] Please refer to Figure 3 More preferably, the plurality of protrusions 106 are disposed on two inner side walls of the liquid storage chamber 103 that are opposite to each other, and the protrusions 106 on the two inner side walls of the liquid storage chamber 103 that are opposite to each other are staggered with each other.

[0040] When squeezing the nose pad body 101, it can be squeezed from both sides of the protrusion 106, so that the protrusions 106 on both sides can have a larger stroke by being offset from each other, so that the volume of the liquid storage cavity 103 can be compressed smaller and more volatile liquid can be sucked in by negative pressure.

[0041] When the liquid storage cavity 103 is at its maximum volume, the virtual volume formed in the liquid storage cavity 103 accounts for 5%-70% of the volume of the nose pad body 101 when covering the slow-release hole. The virtual volume is converted from the volume in the liquid storage cavity 103.

[0042] The corresponding capacity volume can be set according to the volatilization speed and the required endurance time. If it is necessary to meet the use of a single day, the above ratio can be set to a larger value, such as 50%-70%. That is, when the volume of the above nose pad body remains unchanged, the space in the liquid storage cavity is correspondingly increased.

[0043] When the volatilization speed is set by controlling the number of protrusions 106, the volatilization duration can be set by combining the capacity volume and the number of protrusions.

[0044] In the embodiment of the utility model, a magnet 102 is provided on the nose pad body 101 , and the nose pad body 101 is magnetically matched with the corresponding magnetically attracted portion 22 on the applied eyeglass bracket 1 through the magnet 102 .

[0045] The magnetically attracted part 22 can be a part that has magnetic force itself or a part that does not have magnetic force but can be magnetically attracted, a part that does not have magnetic force but can be magnetically attracted such as an iron block, or a part that has magnetic force itself such as a magnet. The corresponding selection can be made according to the needs. The magnetically attracted part 22 is usually installed on the nose support bracket 11 of the eyeglass bracket 1. Figure 4 As shown, the magnetically attracted portion 22 can be mounted on the nose pad bracket 11 by means of screws 23 .

[0046] The magnetic attraction design can quickly remove the nose pad 10 from the nose pad bracket 11, and can quickly install the nose pad 10 on the nose pad bracket 11. The detachable design of the above application makes the process of adding volatile liquid more convenient.

[0047] The magnetically attracted portion 22 is preferably a component having the same magnetic force. The magnet 102 and the magnetically attracted portion 22 are magnetically attracted to each other, and the structure is more stable during application and installation.

[0048] A magnet mounting hole 105 is formed on the outer side of the nose pad body 101, and the magnet 102 is mounted on the magnet mounting hole 105. The nose pad body 101 is configured to squeeze and tighten the magnet 102 located in the magnet mounting hole 105 to form a secure connection. After the nose pad body 101 is prepared, the magnet 102 can be squeezed into the magnet mounting hole of the nose pad body with an elastic structure or squeezed into the magnet mounting hole of the nose pad body with a soft structure.

[0049] The length of the nose pad body 101 is any value between 1.25 cm and 1.75 cm. Figure 2 The width of the nose pad body 101 is any value between 0.5cm-1cm, such as Figure 2 The width in the left-right direction shown.

[0050] The magnet is a cylindrical magnet, the diameter of the magnet is any value between 1mm and 5mm, and the height of the magnet is any value between 0.5mm and 8mm. Figure 2 As shown, the magnet 102 is pressed into the magnet mounting hole along its axial direction.

[0051] In the embodiment of the present invention, the diameter of the slow-release hole 104 is any value between 0.1 mm and 2 mm, and the number of the slow-release holes 104 is any value between 1 and 200. The slow-release holes 104 are fine micropores. When the number of the slow-release holes 104 is large, the multiple slow-release holes 104 can be as follows: Figure 2 The gathering openings shown are arranged on the nose pad body 101. The volatile liquid is released evenly and slowly through the gathering openings on the surface of the nose pad body 101, and the negative pressure addition of the volatile liquid is facilitated.

[0052] When the pore diameter remains unchanged, the number of the slow-release holes 104 affects the slow-release rate of the volatile gas on the one hand, and directly affects the addition speed of the volatile liquid on the other hand. Therefore, the number of slow-release holes is preferably moderate, such as 100, which has a faster addition speed of the volatile liquid on the one hand, and a moderate slow-release speed on the other hand, which is more conducive to long-term use.

[0053] The volatile liquid in the liquid storage chamber 103 is the infiltration liquid of the inner wall of the liquid storage chamber, forming a capillary phenomenon to increase the volatilization surface area, and when it is matched with the protrusion 106, the capillary phenomenon can be better applied, and the protrusion 106 is used to further increase the volatilization surface area. Through the tiny pore size and capillary phenomenon, the volatile liquid in the liquid storage chamber 103 is not easy to overflow, but slowly volatilizes and releases through the slow-release hole.

[0054] The preparation process may be to first determine the composition of the volatile liquid to be used, and then select a material that can form an infiltrative liquid according to the composition of the volatile liquid to prepare the nose pad body.

[0055] It is worth mentioning that, as a nose pad applied to glasses, glasses using the nose pad are actually disclosed at the same time.

[0056] The material selection of the nose pad body is preferably made of a material that can withstand a certain external pressure without deformation, so that when the nose pad is applied to glasses and worn by the user, it can support the glasses frame and additional components such as lenses on the glasses frame without being easily deformed or causing the space in the liquid storage cavity to be compressed, such as a polyurethane material with a certain hardness.

[0057] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
