[0043] The present invention proposes an eye protector 1000, which aims to solve the problem that the heating component 20 is prone to overheating and damage after long-term use.

[0044] The specific structure of the eye protector 1000 of the present invention will be described below, and the use state of the eye protector 1000 (i.e., when worn) will be used as an example for description:

[0045] Combined with reference Figure 1 , Figure 2 , Figure 4 and Figure 8 In one embodiment of the eye protector 1000 of the present invention, the eye protector 1000 includes a shell 10, a heating component 20 and a flexible outer film 30; an installation cavity is formed in the shell 10, and the shell 10 is provided with an installation port 121, an air inlet 111 and an air outlet 112 connected to the installation cavity; the heating component 20 is arranged in the installation cavity; the flexible outer film 30 is arranged at the installation port 121 and contacts the heating component 20, and the outer side of the flexible outer film 30 is used to fit the user's eyes.

[0046] It can be understood that the eye protector 1000 of the present invention forms an installation cavity in the shell 10, and opens an installation port 121, an air inlet 111 and an air outlet 112 connected to the installation cavity on the shell 10; wherein the heating component 20 is arranged in the installation cavity, and the flexible outer film 30 is arranged at the installation port 121 and contacts the heating component 20; in this way, when the user wears the eye protector 1000, the user's eyes will be fitted with the outer side of the flexible outer film 30, and after starting to work, the heat generated by the heating component 20 will be transferred to the flexible outer film 30, so as to apply heat to the user's eyes through the flexible outer film 30 to relieve eye fatigue; and after working for a period of time, the external airflow can enter the air duct 213 through the air inlet 111 to exchange heat with the heating component 20 in the installation cavity, and the airflow after heat exchange will be blown out through the air outlet 112, so that the heating component 20 can be cooled, thereby solving the problem that the heating component 20 is prone to overheating and damage after long-term use.

[0047] In this embodiment, the eye protector 1000 further includes a circuit board, which is disposed in the housing 10 and electrically connected to the heating element 22 in the heating assembly 20 to provide electrical energy to the heating element 22 and drive the heating element 22 to work and generate heat.

[0048] Specifically, the outer shape of the housing 10 is roughly similar to that of ordinary glasses, so that the eye protector 1000 fits the user's eyes better during use, thereby improving the wearing comfort. The housing 10 can be made of plastic, metal, etc. The flexible outer membrane 30 can be a silicone piece or a rubber piece.

[0049] During use, the outer side of the flexible outer film 30 is the side facing the user's eyes, and is used to fit the user's eyes to apply hot compress to the user's eyes.

[0050] In actual application, the heating component 20 is arranged in the installation cavity of the shell 10. After the air flow enters the installation cavity through the air inlet 111, the air flow can flow along the outer surface of the heating component 20 to take away the heat from the outer surface of the heating component 20; or, after the air flow enters the installation cavity through the air inlet 111, the air flow can flow along the air duct 213 inside the heating component 20 to take away the heat from the inside of the heating component 20; or, after the air flow enters the installation cavity through the air inlet 111, part of the air flow can flow along the outer surface of the heating component 20, and part of the air flow can flow along the inside of the heating component 20 to simultaneously drive the heat from the outer surface and the inside of the heating component 20.

[0051] Combined with reference Figure 4 , Figure 5 and Figure 8 In one embodiment of the eye protection device 1000 of the present invention, an air duct 213 passing through the heating component 20 is formed between the air inlet 111 and the air outlet 112, and the air inlet 111 and the air outlet 112 are both connected to the air duct 213. In this way, after the airflow enters from the air inlet 111, it can flow to the air duct 213 inside the heating component 20 to take away the heat inside the heating component 20, thereby achieving the effect of rapid heat dissipation.

[0052] Specifically, the housing includes an upper housing 11 and a lower housing 12; the air inlet 111 and the air outlet 112 are both provided on the upper housing 11, and the installation opening 121 is provided on the lower housing 12; the upper housing 11 is covered on the lower housing 12, and the upper housing 11 and the lower housing 12 are combined to form an installation cavity. In this arrangement, before assembly, the upper housing 11 is first opened, and after the heating component 20 is assembled into the installation cavity, the upper housing 11 is covered on the lower housing 12, and the upper housing 11 is fixedly connected together by means of screws, buckles 2225, etc., so as to facilitate the installation of the heating component 20.

[0053] Combined with reference Figure 2 In one embodiment of the eye protector 1000 of the present invention, the heating component 20 includes a heat conductive member 21 and a heating member 22; the heat conductive member 21 is formed with the air duct 213, and the heat conductive member 21 is provided with an avoidance hole 2121 connected to the air duct 213; the heating member 22 is passed through the avoidance hole 2121, the inner surface of the heating member 22 is arranged facing the air duct 213, and the outer surface of the heating member 22 is in contact with the flexible outer film 30.

[0054] With such arrangement, the heating element 22 can be fixedly installed in the installation cavity of the shell 10 through the heat-conducting element 21 to ensure the installation stability of the heating element 22; in addition, the heating element 22 is passed through the avoidance hole 2121 of the heat-conducting element 21, and the inner surface of the heating element 22 is arranged facing the air duct 213; in this way, the airflow flowing through the air duct 213 can not only take away the heat in the air duct 213, but also take away the heat on the inner surface of the heating element 22, so as to achieve the effect of rapid heat dissipation; at the same time, the outer surface of the heating element 22 is in contact with the flexible outer film 30, so that the heat can be transferred to the flexible outer film 30 through the outer surface of the heating element 22, so as to perform hot compress on the user's eyes through the flexible outer film 30.

[0055] Specifically, the heat conducting member 21 may be heat conducting silica gel, heat conducting rubber, heat conducting metal, etc.

[0056] Combined with reference Figures 2 to 5 In one embodiment of the eye protector 1000 of the present invention, the heat conductive member 21 includes a first mounting plate 211 and a second mounting plate 212, the first mounting plate 211 is covered on the second mounting plate 212, and is clamped with the second mounting plate 212 to form the air duct 213, the first mounting plate 211 is provided with a first through hole 2111 connecting the air inlet 111 and the air duct 213, the first mounting plate 211 is also provided with a second through hole 2112 connecting the air outlet 112 and the air duct 213, and the second mounting plate 212 is provided with the avoidance hole 2121; wherein, the airflow flows through the air inlet 111, the first through hole 2111, the air duct 213, the second through hole 2112 and the air outlet 112 in sequence.

[0057] With such arrangement, the airflow entering from the air inlet 111 can flow into the air duct 213 through the first through hole 2111, and the airflow after heat exchange in the air duct 213 can flow toward the air outlet 112 through the second through hole 2112, so as to be blown out through the air outlet 112, thereby taking away the heat in the air duct 213.

[0058] Specifically, one or more first through holes 2111 may be provided. When multiple first through holes 2111 are provided, the multiple first through holes 2111 are all connected to the air inlet 111 and the air duct 213. Similarly, one or more second through holes 2112 may be provided. When multiple second through holes 2112 are provided, the multiple second through holes 2112 are all connected to the air outlet 112 and the air duct 213.

[0059] During the assembly process, the second mounting plate 212 can first be fixedly connected to the lower shell 12 of the shell 10 by means of screws, clips, etc., and then the first mounting plate 211 can be fixedly connected to the side of the first mounting plate 211 facing away from the lower shell 12 by means of screws, clips, etc., and then the upper shell 11 is covered on the lower shell 12 and fixedly connected together by means of screws, clips, etc.

[0060] Furthermore, in order to allow the airflow passing through the air duct 213 to smoothly enter the avoidance hole 2121 so as to take away the heat of the heating element 22 in the avoidance hole 2121, a guide hole connected to the avoidance hole 2121 may be opened on the second mounting plate 212, and the guide hole is located on a side of the avoidance hole 2121 close to the first through hole 2111. In this way, the airflow can be guided to the avoidance hole 2121 under the action of the guide hole.

[0061] Combined with reference Figures 2 to 4 In one embodiment of the eye protector 1000 of the present invention, a first avoidance groove 2113 opposite to and connected to the air inlet 111 is formed on the surface of the first mounting plate 211 facing the air inlet 111, the first avoidance groove 2113 is spaced apart from the first through hole 2111, and a channel 2114 penetrating to the first through hole 2111 is formed on the groove wall of the first avoidance groove 2113.

[0062] With such arrangement, the airflow led out from the air inlet 111 first enters the first avoidance groove 2113, then flows from the first avoidance groove 2113 to the first through hole 2111 through the channel 2114, and finally enters the air duct 213 through the first through hole 2111. In this way, the airflow can fully flow through various positions of the first mounting plate 211 to take away the heat at various positions of the first mounting plate 211, thereby further improving the heat dissipation efficiency of the heat-generating component 20.

[0063] Further, see Figure 6 A third avoidance groove 2116 is also provided on the surface of the first mounting plate 211 facing the second mounting plate 212, and the first through hole 2111 passes through the surface of the first mounting plate 211 facing away from the second mounting plate 212 to the bottom of the third avoidance groove 2116, and the third avoidance groove 2116 connects the first through hole 2111 and the air duct 213; in this way, the airflow can further fully flow through various positions of the first mounting plate 211 to take away the heat at various positions of the first mounting plate 211, thereby further improving the heat dissipation efficiency of the heat-generating component 20.

[0064] Further, see Figure 2In one embodiment of the eye protector 1000 of the present invention, the outer surface of the first mounting plate 211 surrounding the notch of the first avoidance groove 2113 abuts against the inner surface of the housing 10 surrounding the air inlet 111. In this way, it is ensured that the airflow introduced by the air inlet 111 flows through the first avoidance groove 2113, the channel 2114, the first through hole 2111 and the air duct 213 in sequence, so as to fully take away the heat inside the heating component 20, and prevent most of the airflow introduced by the air inlet 111 from being directly blown out to the air outlet 112 along the outer surface of the heating component 20, thereby affecting the heat dissipation effect of the heating component 20.

[0065] Combined with reference Figures 2 to 4 In one embodiment of the eye protector 1000 of the present invention, a second avoidance groove 2115 opposite to and connected to the air outlet 112 is provided on the surface of the first mounting plate 211 facing the air outlet 112, and the second through hole 2112 is provided at the bottom of the second avoidance groove 2115.

[0066] With such arrangement, the airflow in the air duct 213 flows to the second avoidance groove 2115 after passing through the second through hole 2112, and then flows to the air outlet 112 from the second avoidance groove 2115 to be blown outward, so that the airflow can further fully flow through various positions of the first mounting plate 211 to take away the heat at various positions of the first mounting plate 211, thereby further improving the heat dissipation efficiency of the heat-generating component 20.

[0067] Further, see Figure 2 In one embodiment of the eye protector 1000 of the present invention, the outer surface of the first mounting plate 211 surrounding the notch of the second avoidance groove 2115 abuts against the inner surface of the housing 10 surrounding the air outlet 112. With such a configuration, it is ensured that the airflow blown out of the air duct 213 flows through the second through hole 2112 and the second avoidance groove 2115 in sequence, and blows out through the air outlet 112, so as to further fully take away the heat inside the heating component 20, and prevent the airflow introduced into the second avoidance groove 2115 from flowing back to the air inlet 111, thereby affecting the air intake of the air inlet 111, and further affecting the heat dissipation effect of the heating component 20.

[0068] Combined with reference Figures 4 to 6In one embodiment of the eye protector 1000 of the present invention, a stopper 2117 is convexly provided on the surface of the first mounting plate 211 facing the second mounting plate 212, and the inner surface of the heating element 22 is attached to the surface of the stopper 2117 facing away from the first mounting plate 211. In this way, by attaching the inner surface of the heating element 22 to the surface of the stopper 2117 facing away from the first mounting plate 211, not only the installation stability of the heating element 22 can be ensured, but also the contact area between the heating element 22 and the first mounting plate 211 can be increased, so that the heat of the heating element 22 can be better transferred to the first mounting plate 211, thereby improving the heat dissipation efficiency of the heating element 22.

[0069] Further, see Figure 7 The surface of the heating film facing the avoidance hole 2121 is convexly provided with a limiting boss 31, the limiting boss 31 is arranged opposite to the limiting block 2117, and the heating element 22 is sandwiched between the limiting boss 31 and the limiting block 2117. In this way, the heating element 22 can be clamped and fixed under the action of the limiting boss 31 and the limiting block 2117 to further ensure the installation stability of the heating element 22; and the heating element 22 can also be closely fitted with the table surface of the limiting boss 31 of the flexible outer film 30, so that the heat of the heating element 22 is fully transferred to the flexible outer film 30 to ensure the hot compress effect on the user's eyes.

[0070] Combined with reference Figure 4 and Figure 6 In one embodiment of the eye protector 1000 of the present invention, a clearance groove 2118 is provided on the surface of the first mounting plate 211 facing the second mounting plate 212, and a support platform 2122 is protruding from the surface of the second mounting plate 212 facing the first mounting plate 211, and the surface of the support platform 2122 abuts against the bottom of the clearance groove 2118, and the support platform 2122 is gap-matched with the groove wall of the clearance groove 2118.

[0071] In this way, the support platform 2122 of the second mounting plate 212 is inserted into the air avoidance groove 2118 of the first mounting plate 211, and the table top of the support platform 2122 is abutted against the bottom of the air avoidance groove 2118, so as to improve the installation stability between the first mounting plate 211 and the second mounting plate 212; in addition, the gap between the support platform 2122 and the groove wall of the air avoidance groove 2118 is matched, so that the gap between the support platform 2122 and the groove wall of the air avoidance groove 2118 constitutes a part of the air duct 213.

[0072] Furthermore, in order to quickly position the first mounting plate and the second mounting plate during the assembly process to facilitate subsequent assembly, a positioning hole may be opened at the bottom of the avoidance groove 2118, and a positioning piece may be provided on the surface of the support platform 2122. By passing the positioning piece through the positioning hole, the first mounting plate and the second mounting plate can be quickly positioned; specifically, the positioning hole may be a strip hole, and the positioning piece may be a strip positioning block adapted to the strip hole.

[0073] Combined with reference Figure 8 In one embodiment of the eye protector 1000 of the present invention, the eye protector 1000 further includes a fan 40, which is disposed in the installation cavity and is used to introduce airflow from the air inlet 111 and blow the airflow out from the air outlet 112. In this arrangement, the external airflow can be introduced into the installation cavity from the air inlet 111 under the action of the fan 40, and the airflow in the installation cavity after heat exchange can be blown out from the air outlet 112 to improve the heat dissipation efficiency of the heating element 22.

[0074] Specifically, the air duct 213 has an installation space for installing the fan 40 , and the installation space is arranged close to the air outlet 112 .

[0075] Combined with reference Figure 1 In one embodiment of the eye protection device 1000 of the present invention, a sunken platform is provided on the outer wall of the housing 10, and the air outlet 112 is opened on the surface of the sunken platform. In this way, the air outlet 112 is opened at the sunken platform of the housing 10 to ensure the beauty of the eye protection device 1000.

[0076] In addition, a plurality of air outlets 112 are provided, and the plurality of air outlets 112 are spaced apart on the outer wall of the housing 10 , so that the hot air in the air duct 213 can be evenly blown outward through the plurality of air outlets 112 to ensure the heat dissipation efficiency of the heating element 22 .

[0077] In one embodiment, in conjunction with reference to Figure 1 , Figure 8 and Fig. 9 The eye protector 1000 includes a connecting member 200 and two eye masks 100, wherein the two eye masks 100 are rotatably connected to the two ends of the connecting member 200, so that the eye masks 100 can be universally rotated relative to the connecting member 200; wherein the two eye masks 100 both include the shell 10, the heating component 20 and the flexible outer membrane 30 as described above.

[0078] With such arrangement, since both eye masks 100 can be universally rotated relative to the connecting member 200, the user can rotate the two eye masks 100 according to the size of his / her face before use to complete the adaptation, thereby being able to adapt to users with different face sizes.

[0079] In addition, the user can also rotate the angle between the two eye masks 100 at any time during use to adjust the two eye masks 100 to a more comfortable angle for the user, or after using for a period of time, by rotating the angle between the two eye masks 100, different positions of the user's eyes can be relaxed to achieve the effect of fully relieving eye fatigue.

[0080] In actual application, universal balls 223 may be provided at both ends of the connecting member 200, and each eye mask 100 may be rotatably connected to the universal balls 223, so that the eye mask 100 may be universally rotatable relative to the connecting member 200; or, each eye mask 100 may have a universal ball 223, and the two ends of the connecting member 200 may be rotatably connected to the two universal balls 223, so that the eye mask 100 may be universally rotatable relative to the connecting member 200.

[0081] Further, see Figure 3 and Figure 4 , both ends of the connecting member 200 have universal balls 223, the first mounting plate 211 of the eye mask 100 has a mounting slot, the mounting slot is arranged opposite to the air inlet 111 of the housing 10, and each universal ball 223 is rotatably arranged through an air inlet 111 and inserted into a mounting slot. In this way, by rotatably traversing an air inlet 111 and inserting each universal ball 223 into a mounting slot, each eye mask 100 can be universally rotated relative to the connecting member 200, so as to adjust the angle and position between the two eye masks 100 at will.

[0082] Further, see Figure 1 , Figure 8 and Fig.10 The connecting member 200 includes a mounting shell 210 and two connecting structures 220; a cavity is formed in the mounting shell 210, and through holes 2011 communicating with the cavity are provided at both ends of the mounting shell 210; each of the connecting structures 220 is inserted through one of the through holes 2011, and one of the ends of each of the connecting structures 220 located outside the mounting shell 210 is provided with a universal ball 223. In this way, by inserting each of the connecting structures 220 through a through hole 2011 of the housing 10, the connection strength between the connecting structure 220 and the mounting shell 210 is ensured, thereby ensuring the installation stability of the connecting structure 220 and preventing the connection structure 220 from being separated from the mounting shell 210 during use; in addition, by connecting the universal ball 223 to one end of the connecting structure 220 located outside the mounting shell 210, the universal ball 223 can be easily inserted into the mounting groove of the eye mask 100, so that the eye mask 100 can achieve the function of universal rotation.

[0083] Further, see Fig. 9 , Fig.11 and Fig.12The connection structure 220 includes a connection rod 221 and a connection block 222; one end of the connection rod 221 is inserted into the through hole 2011 and inserted into the cavity, and the universal ball 223 is connected to the end of the connection rod 221 located outside the mounting shell 210; the connection block 222 is arranged in the cavity and sleeved on the connection rod 221. In this way, during the assembly process, one end of the connection rod 221 is first inserted into the through hole 2011 and inserted into the cavity, and then the connection block 222 is sleeved on the end of the connection rod 221 located in the cavity, so that the connection rod 221 can be connected to the mounting shell 210, so as to facilitate the assembly of the connection structure 220 and the mounting shell 210.

[0084] Further, see Figure 12 to Figure 14 The outer wall of the connecting block 222 is provided with a first connecting hole 2223, the inner wall of the connecting block 222 is provided with a clearance notch 2224 connected to the first connecting hole 2223, the side wall of the connecting rod 221 is provided with a positioning groove 2213, the notch of the positioning groove 2213 is arranged toward the clearance notch 2224, and the connecting structure 220 further includes a connecting column 225, the connecting column 225 is penetrated through the first connecting hole 2223, and the portion of the connecting column 225 protruding from the clearance notch is accommodated in the positioning groove 2213. In this way, the connecting column 225 can be penetrated through the first connecting hole 2223 and the portion of the connecting column 225 protruding from the clearance notch is accommodated in the positioning groove 2213, so as to ensure the connection strength between the connecting block 222 and the connecting rod 221, thereby preventing the connecting rod 221 from rotating relative to the connecting block 222 and affecting the installation stability of the connecting rod 221. Optionally, the connecting column 225 can be a screw.

[0085] Further, see Fig.11 and Fig.13 A limiting strip 2011a is protruded on opposite sides of the hole wall of the through hole 2011, and the limiting strip 2011a has a first abutting plane facing the connecting rod 221. The two first abutting planes are arranged opposite to each other. The connecting rod 221 has two second abutting planes 2211 arranged back to back. Each of the first abutting planes is abutted or gap-fitted with one of the second abutting planes 2211.

[0086] With such arrangement, the eye mask 100 can easily transmit external force to the universal ball 223 during rotation, and thus the external force can be transmitted to the connecting structure 220 through the universal ball 223. When the external force is too large, the connecting structure 220 can easily rotate relative to the mounting shell 210, thereby affecting the mounting stability of the connecting structure 220. Therefore, a limiting strip 2011a is provided on the hole wall of the through hole 2011, so that the limiting strip 2011a has a first abutting plane facing the connecting rod 221, and the connecting rod 221 has two second abutting planes 2211 arranged back to back. In this way, each first abutting plane can abut or clearance-match with a second abutting plane 2211 to limit the connecting rod 221, thereby preventing the connecting structure 220 from rotating relative to the mounting shell 210.

[0087] Furthermore, in order to not only be able to universally rotate the eye mask 100 but also to be able to adjust the distance between the two eye masks 100 to further adapt to users with different face sizes, the arrangement direction of the two first abutting planes is made perpendicular to the arrangement direction of the two eye masks 100. In this way, not only the connection structure 220 can be limited, but also the adjustment of the distance between the two eye masks 100 will not be affected.

[0088] Further, see Fig.13 and Fig.14 The inner wall of the connecting block 222 has two third abutting planes 2221 arranged opposite to each other, and the connecting rod 221 has two fourth abutting planes 2212 arranged opposite to each other, and each of the third abutting planes 2221 abuts against or has a clearance fit with one of the fourth abutting planes 2212. Similarly, by making the inner wall of the connecting block 222 have the third abutting planes 2221 arranged opposite to each other, and making the connecting rod 221 have the two fourth abutting planes 2212 arranged opposite to each other, each of the third abutting planes 2221 abuts against or has a clearance fit with one of the fourth abutting planes 2212, so as to further limit the position of the connecting rod 221, thereby preventing the connecting rod 221 from rotating relative to the connecting block 222.

[0089] Similarly, in order to not only be able to universally rotate the eye mask 100 but also to be able to adjust the distance between the two eye masks 100 to further adapt to users with different face sizes, the arrangement direction of the two third abutting planes 2221 is made perpendicular to the arrangement direction of the two eye masks 100. In this way, not only the connection structure 220 can be limited, but also the adjustment of the distance between the two eye masks 100 will not be affected.

[0090] Further, see Fig.11A mounting hole for accommodating the end of the connecting rod 221 is formed in the middle of the connecting block 222, and a limiting groove 2021 is provided on the inner wall of the mounting shell 210 facing the mounting hole. Two oppositely arranged limiting baffles 2222 are provided on the side of the connecting block 222 facing the limiting groove 2021. The two limiting baffles 2222 are respectively located on both sides of the avoidance hole 2121, and each limiting baffle 2222 has a limiting plane facing away from the other limiting baffle 2222. The two limiting planes are respectively abutted or gap-fitted with the two side walls opposite to the limiting groove 2021. Similarly, a limiting groove 2021 is provided on the inner wall of the mounting shell 210 facing the avoidance hole 2121, and two relatively arranged limiting baffles 2222 are provided on the side of the connecting block 222 facing the limiting groove 2021, and each limiting baffle 2222 has a limiting plane facing away from the other limiting baffle 2222. In this way, the two limiting planes can be respectively abutted or gap-fitted with the two side walls opposite to the limiting groove 2021 to limit the connecting block 222, thereby preventing the connecting block 222 from rotating relative to the mounting shell 210.

[0091] Similarly, in order to not only be able to universally rotate the eye mask 100 but also to be able to adjust the distance between the two eye masks 100 to further adapt to users with different face sizes, the length direction of the limiting groove 2021 is consistent with the arrangement direction of the two eye masks 100, that is, the arrangement direction of the two limiting planes is consistent with the arrangement direction of the two eye masks 100. In this way, not only the connection structure 220 can be limited, but also the adjustment of the distance between the two eye masks 100 will not be affected.

[0092] Further, see Fig. 9 The connection structure 220 further includes a connection sleeve 224, which is sleeved on one end of the connection rod 221 located outside the mounting shell 210 and covers the notch of the mounting slot. In such a configuration, in order to enable the universal ball 223 of the connecting structure 220 to be smoothly installed in the installation groove of the eye mask 100, the notch of the installation groove needs to be opened large enough, at least consistent with the diameter of the universal ball 223, so as to ensure that the universal ball 223 can be smoothly inserted into the installation groove. At this time, after the universal ball 223 is installed in the installation groove, due to the large notch of the installation groove, the universal ball 223 is easy to fall out of the installation groove during the rotation process; therefore, by sleeve-arranging a connecting sleeve 224 at one end of the connecting rod 221 located outside the installation shell 210, and making the connecting sleeve 224 sleeved in the notch of the installation groove, the universal ball 223 can be limited in the installation groove by the connecting sleeve 224. This configuration can not only ensure that the universal ball 223 can rotate freely in the installation groove, but also prevent the universal ball 223 from falling out of the installation groove during use.

[0093] Specifically, the connecting sleeve 224 can be fixedly connected to the eye mask 100 by means of screws, buckles, etc., so as to limit the universal ball 223 in the installation groove.

[0094] Furthermore, in order to prevent the connecting sleeve 224 from hindering the rotation of the universal ball 223, optionally, the connecting sleeve 224 includes a connecting cylinder and a bearing, the bearing is sleeved on the connecting rod 221, and the connecting cylinder is sleeved on the bearing, so that the connecting sleeve 224 can be effectively prevented from hindering the rotation of the universal ball 223.

[0095] Further, see Fig. 9 The through hole 2011 is a strip-shaped through hole 2011, the length direction of the strip-shaped through hole 2011 is consistent with the arrangement direction of the two eye masks 100, and the connecting structure 220 is slidably arranged along the length direction of the strip-shaped through hole 2011. In this way, before use, the user can adjust the distance between the two eye masks 100 by moving the eye masks 100 to drive the connecting structure 220 to slide along the length direction of the strip-shaped through hole 2011 through the eye masks 100, so as to further adapt to users with different face sizes.

[0096] Further, see Fig. 9 The inner wall of the mounting shell 210 is provided with a plurality of slots 2012, and the plurality of slots 2012 are arranged at intervals along the length direction of the through hole 2011; one end of the connecting structure 220 disposed in the cavity has a buckle 2225, and the connecting structure 220 slides so that the buckle 2225 is locked in one of the slots 2012. In this way, when the distance between the two eye masks 100 needs to be adjusted, the user can move the eye masks 100 to drive the connecting structure 220 to slide along the length direction of the strip through hole 2011 through the eye masks 100, and make the buckle 2225 on the connecting structure 220 escape from one of the slots 2012 and be locked in another slot 2012, so as to limit the connecting structure 220 at the position required by the user.

[0097] Furthermore, in order for the user to accurately and quickly adjust the eye mask 100 to the previously used spacing, the position of the mounting shell 210 corresponding to the slot 2012 can be set to a transparent structure, so that the user can observe the structure of the buckle 2225 and the slot 2012, thereby facilitating the user to accurately and quickly adjust the eye mask 100 to the previously used spacing.

[0098] Further, see Fig.11The inner wall of the installation shell 210 is provided with a slide rail 2013, and the slide rail 2013 is extended along the length direction of the strip-shaped through hole 2011. One end of the connection structure 220 disposed in the cavity has a slide groove 2226, and the slide groove 2226 is extended along the length direction of the strip-shaped through hole 2011. The slide rail 2013 is disposed in the slide groove 2226, so that the connection structure 220 slides along the extension direction of the slide rail 2013. In this way, the connection structure 220 can slide smoothly along the extension direction of the slide rail 2013 under the cooperation of the slide rail 2013 and the slide groove 2226, and the sliding track of the connection structure 220 is guaranteed to prevent the connection structure 220 from deviating from the track during the sliding process, thereby affecting the use effect.

[0099] Further, see Fig.11 The installation shell 210 includes a bottom shell 201 and an upper cover 202; the through hole 2011 is opened in the bottom shell 201; the upper cover 202 is covered on the bottom shell 201 and enclosed with the bottom shell 201 to form the cavity. In this arrangement, before assembly, the upper cover 202 is first opened, and the two connecting structures 220 are respectively installed to the corresponding positions, and then the upper cover 202 is covered on the bottom shell 201, and fixedly connected together by means of screws, buckles, etc., so as to facilitate the installation of the connecting structure 220.
