Description

Technical Field

[0001] This utility model relates to the field of massager technology, and in particular to an eye massager. Background Technology

[0002] In daily life and work, prolonged use of the eyes can cause eye fatigue. Eye massagers can effectively massage and relax the eyes to relieve eye fatigue.

[0003] As disclosed in patent CN117618228A, an eye massager includes a housing, an inner liner assembly disposed within the housing, and a control component disposed outside the housing. The inner liner assembly includes an inner liner and a massage component disposed within the inner liner. The control component is electrically connected to the massage component via a socket assembly, which includes a first pair of connectors and a second pair of connectors connected by plugging. The control component includes a control box and a circuit component disposed within the control box, which is used to power the eye massager and control the opening and closing of the massage component and its working mode. Furthermore, the inner liner assembly can be removed from the housing, and the control component is detachably connected to the housing, allowing the housing and the inner liner assembly to be cleaned separately.

[0004] In the aforementioned eye massager structure, because the inner liner is simply placed inside the housing, it has been found during use that the inner liner is prone to moving within the housing, affecting the electrical connection between the first and second pairs of connectors in the socket assembly. Furthermore, repositioning the inner liner after removing it from the housing is inconvenient. Utility Model Content

[0005] The purpose of this utility model is to provide an eye massager that uses a retaining ring to secure the electrical connection component. This not only prevents the inner liner component from moving within the housing and ensures the electrical connection between the control box and the electrical connection component, but also facilitates the positioning and installation of the inner liner component and the housing.

[0029] The directional terms such as "up," "down," "left," "right," "front," "back," "top," and "bottom" (if present) used in the specification and claims of this utility model are defined according to the position of the structures in the drawings and the relative positions of the structures, and are only for the purpose of clarity and convenience in expressing the technical solution. It should be understood that the use of directional terms should not limit the scope of protection claimed by this utility model.

[0030] like Figures 1 to 10 As shown, the eye massager provided in this embodiment of the present invention includes a housing 1, an inner liner assembly 2 disposed within the housing 1, and a control box 3 disposed outside the housing 1. The inner liner assembly 2 includes an inner liner 21 and a massage component 23 disposed within the inner liner 21. The massage component 23 is used to massage the human eye area. An electrical connection component 22 is provided on the side wall of the inner liner 21, and the electrical connection component 22 is electrically connected to the massage component 23. A through hole 11 is provided on the side wall of the housing 1 corresponding to the position of the electrical connection component 22. A retaining ring 4 is fixedly disposed in the through hole 11. The retaining ring 4 has a hollow annular structure. The electrical connection component 22 is held in the retaining ring 4 and is detachably connected to the retaining ring 4. The electrical connection component 22 protrudes outside the housing 1 through the retaining ring 4. The control box 3 is installed on the outer wall of the electrical connection component 22, and the control box 3 is electrically connected to the electrical connection component 22, and the control box 3 is detachably connected to the electrical connection component 22. The control box 3 is used to power the eye massager and control the opening and closing of the massage component 23 and its working mode.

[0031] Meanwhile, the shell 1 has a notch (not shown in the figure), located on the side of the shell 1, communicating with the inner cavity of the shell 1. An opening / closing element (not shown in the figure) is provided at the notch, connected to the shell 1, and used to open or close the notch (i.e., when the opening / closing element is opened, the notch is open; when the opening / closing element is closed, the notch is closed). When the notch is open, the inner liner assembly 2 can be removed from the shell 1 through the notch. The opening / closing element can be a zipper or a magnetic strip assembly, etc. For details regarding the structure and location of the notch and opening / closing element, please refer to the applicant's previous patent application (e.g., CN117618228A), which will not be elaborated here.

[0032] The eye massager provided in this embodiment has a notch on the housing 1 and an opening and closing component at the notch. When the notch is opened, the inner shell component 2 can be taken out of the housing 1 through the notch, so that the housing 1 and the inner shell component 2 can be deeply cleaned separately without worrying about the inner shell component 2 getting wet. Moreover, the inside of the housing 1 can also be cleaned, thereby improving the cleaning effect of the housing 1 and thus improving the user experience and service life of the eye massager.

[0033] Meanwhile, by providing a through hole 11 on the side wall of the housing 1, and fixing a retaining ring 4 inside the through hole 11, the electrical connection component 22 on the inner liner assembly 2 is engaged and fixed with the retaining ring 4, and the electrical connection component 22 protrudes outside the housing 1 through the retaining ring 4. With this arrangement, on the one hand, when the control box 3 is connected to the electrical connection component 22, the control box 3 and the electrical connection component 22 come into contact and are electrically connected. Moreover, since the electrical connection component 22 is engaged and fixed by the retaining ring 4, the position of the electrical connection component 22 can be prevented from changing, thereby ensuring the stability of the electrical connection between the control box 3 and the electrical connection component 22. On the other hand, since the electrical connection component 22 is engaged and fixed by the retaining ring 4, the inner liner assembly 2 and the housing 1 can be disassembled. After the inner liner assembly 2 is disassembled from the housing 1 and taken out of the housing 1, when the inner liner assembly 2 is put back into the housing 1, the engagement of the electrical connection component 22 with the retaining ring 4 facilitates the positioning and installation of the inner liner assembly 2 and the housing 1 (i.e., there is no need to adjust the position of the inner liner assembly 2 multiple times to align the electrical connection component 22 with the through hole 11).

[0034] like Figures 1 to 7 As shown, in one embodiment, the housing 1 has a flat structure and is made of a flexible, soft material. This allows the housing 1 to bend and conform to the human face when worn, and the soft material of the housing 1 improves wearing comfort. The housing 1 can be made of materials such as fabric, cotton-padded leather, or silicone. Of course, in other embodiments, the housing 1 can also be an arched structure that matches the shape of the human face.

[0035] like Figures 1 to 7As shown, in one embodiment, the housing 1 includes a front housing 10A and a rear housing 10B disposed opposite to each other. The rear housing 10B is located on the side of the front housing 10A facing the human eye. A through hole 11 and a retaining ring 4 are disposed on the front housing 10A, and a control box 3 is disposed on the outer wall of the front housing 10A. The edge of the front housing 10A is connected to the edge of the rear housing 10B (i.e., the side of the front housing 10A is connected to the side of the rear housing 10B). A receiving cavity (not labeled) for accommodating the inner liner assembly 2 is formed between the front housing 10A and the rear housing 10B. The inner liner assembly 2 is disposed in the receiving cavity, and a notch communicates with the receiving cavity 100. The notch is located at the side position where the front housing 10A and the rear housing 10B are connected, and the opening and closing member is connected to both the side of the front housing 10A and the side of the rear housing 10B. Specifically, in this embodiment, the side of the front shell 10A and the side of the rear shell 10B are connected by stitching (of course, they can also be connected by gluing or other methods), and the side of the front shell 10A and the side of the rear shell 10B are not stitched at the notch position, thereby forming a notch at the side position of the shell 1.

[0036] like Figures 3 to 7 As shown, in one embodiment, the inner liner 21 includes a first covering sheet 21A and a second covering sheet 21B disposed opposite to each other. The first covering sheet 21A and the second covering sheet 21B can be made of materials such as fabric. An electrical connection assembly 22 is disposed on the side wall of the first covering sheet 21A. The edges of the first covering sheet 21A and the edges of the second covering sheet 21B are joined together by heat pressing (of course, they can also be joined by adhesive bonding or other methods). During assembly, the massage assembly 23 is first placed between the first covering sheet 21A and the second covering sheet 21B, and then the first covering sheet 21A and the second covering sheet 21B are heat-bonded together.

[0037] In one embodiment, the massage component 23 includes a heating element that generates heat when energized, thereby providing a warm compress and massage to the eye area. Alternatively, in other embodiments, the massage component 23 may include a massage airbag that inflates and deflates, repeating this inflation and deflation process to massage the eye area. Of course, the massage component 23 can also be other types of massage structures.

[0038] like Figures 1 to 10As shown, in one embodiment, the control box 3 includes a box body 31 and a circuit assembly 32 disposed within the box body 31. The circuit assembly 32 includes a first circuit board 321 and a first terminal assembly 322 disposed on the first circuit board 321. The first terminal assembly 322 is electrically connected to the first circuit board 321. A clearance hole 312 is provided on the box body 31 at a position corresponding to the first terminal assembly 322, through which the first terminal assembly 322 protrudes into the box body 31. In this embodiment, the box body 31 includes a first box body 31A and a second box body 31B disposed opposite to each other. The first box body 31A and the second box body 31B can be connected by means of screwing, snap-fitting, etc. The circuit assembly 32 is disposed within the first box body 31A and the second box body 31B, and the clearance hole 312 is disposed on the side wall of the second box body 31B.

[0039] The electrical connection assembly 22 includes a snap-fit ​​base 221, a second circuit board 222, and a second terminal assembly 223 disposed on the second circuit board 222. The second terminal assembly 223 is electrically connected to the second circuit board 222, and the second circuit board 222 is electrically connected to the massage assembly 23 (specifically, the second circuit board 222 is electrically connected to the massage assembly 23 via a wire). The snap-fit ​​base 221 is fixed to the outer wall of the inner liner 21, snaps into the retaining ring 4, and protrudes from the outer shell 1 through the retaining ring 4. The second circuit board 222 is fixed to the inner wall of the inner liner 21, and the second terminal assembly 223 passes through the side wall of the inner liner 21 and the snap-fit ​​base 221 in sequence before protruding from the outer shell 1. Specifically, the inner liner 21 has a first through hole 210, the snap-fit ​​base 221 has a second through hole 2215, and the second terminal assembly 223 passes through the first through hole 210 and the second through hole 2215 in sequence.

[0040] When the housing 31 contacts the card slot 221, the first terminal assembly 322 and the second terminal assembly 223 contact and become electrically connected. That is, the first circuit board 321 and the second circuit board 222 are electrically connected through the first terminal assembly 322 and the second terminal assembly 223, thereby realizing the electrical connection between the control box 3 and the electrical connection assembly 22. In this embodiment, the first terminal assembly 322 includes multiple conductive posts, and the second terminal assembly 223 includes multiple spring pins, each of which contacts one-to-one with a corresponding conductive post.

[0041] like Figures 3 to 7As shown, in one embodiment, the electrical connection assembly 22 further includes a fixing member 224. The fixing member 224 is located on the side of the second circuit board 222 away from the snap-fit ​​seat 221. The second circuit board 222 is sandwiched between the fixing member 224 and the inner wall of the inner liner 21. The fixing member 224 and the snap-fit ​​seat 221 are fixedly connected by screws 226. This arrangement fixes the snap-fit ​​seat 221 and the second circuit board 222 onto the inner liner 21. In this embodiment, a stud 2216 is provided on the side of the snap-fit ​​seat 221 near the fixing member 224. The stud 2216 passes through the side wall of the inner liner 21, and the fixing member 224 is fixedly connected to the stud 2216 by screws 226. In this embodiment, both the snap-fit ​​seat 221 and the fixing member 224 are made of plastic.

[0042] like Figures 2 to 8 As shown, in one embodiment, the snap-fit ​​seat 221 is provided with a snap-fit ​​groove 2210, and the snap-fit ​​ring 4 is snapped into the snap-fit ​​groove 2210, thereby realizing the snap-fit ​​fixation between the snap-fit ​​seat 221 and the snap-fit ​​ring 4. In this embodiment, the snap-fit ​​seat 221 includes a first flat plate portion 2211 and a second flat plate portion 2212 arranged at intervals, and a connecting post 2213 connecting the first flat plate portion 2211 and the second flat plate portion 2212. The first flat plate portion 2211, the second flat plate portion 2212 and the connecting post 2213 are integral structures. The first flat plate portion 2211 and the second flat plate portion 2212 both protrude radially outward relative to the connecting post 2213. The snap-fit ​​groove 2210 is formed between the first flat plate portion 2211, the second flat plate portion 2212 and the connecting post 2213. The snap-fit ​​ring 4 is sleeved on the outside of the connecting post 2213, and the opposite sides of the snap-fit ​​ring 4 abut against the first flat plate portion 2211 and the second flat plate portion 2212 respectively.

[0043] In this embodiment, the first flat plate portion 2211 is located on the side of the second flat plate portion 2212 near the control box 3. The second flat plate portion 2212 abuts against the outer wall of the inner liner 21. The first flat plate portion 2211 has a circular plate structure, the connecting post 2213 has a cylindrical structure, and the second flat plate portion 2212 can be a circular plate structure or a non-circular plate structure (e.g., an elliptical plate structure). The retaining ring 4 has a circular ring structure, and the diameter of the first flat plate portion 2211 is larger than the diameter of the central hole 400 of the retaining ring 4. The retaining ring 4 is made of an elastic material, specifically silicone (of course, in other embodiments, the retaining ring 4 can also be made of elastic materials such as rubber). When the snap-fit ​​base 221 engages with the snap-fit ​​ring 4, the first flat plate portion 2211 passes through the central hole 400 of the snap-fit ​​ring 4, causing the snap-fit ​​ring 4 to engage in the snap-fit ​​groove 2210, thus securing the snap-fit ​​base 221 with the snap-fit ​​ring 4. Simultaneously, as the first flat plate portion 2211 passes through the central hole 400 of the snap-fit ​​ring 4, the snap-fit ​​ring 4 undergoes elastic deformation, causing the central hole 400 of the snap-fit ​​ring 4 to expand, allowing the first flat plate portion 2211 to pass smoothly through the central hole 400 of the snap-fit ​​ring 4. After the snap-fit ​​base 221 and the snap-fit ​​ring 4 are engaged, the first flat plate portion 2211 protrudes outside the housing 1 through the snap-fit ​​ring 4. Therefore, when the control box 3 is installed on the snap-fit ​​base 221, the control box 3 will come into contact with the first flat plate portion 2211.

[0044] like Figures 2 to 5 and Figure 9 and Figure 10 As shown, in one embodiment, the outer wall of the box body 31 is provided with a limiting groove 313 that conforms to the shape of the first flat plate portion 2211. When the control box 3 is installed on the mounting base 221, the first flat plate portion 2211 is located within the limiting groove 313 to align the control box 3 and the mounting base 221. Simultaneously, the mounting base 221 is provided with a protrusion 2214, which is specifically disposed on the first flat plate portion 2211. The outer wall of the box body 31 is provided with an alignment groove 311 that mates with the protrusion 2214. When the box body 31 contacts the mounting base 221, the protrusion 2214 is located within the alignment groove 311, thereby preventing the control box 3 from being placed backwards and serving as a foolproof mechanism.

[0045] like Figures 2 to 5 and Figure 9 and Figure 10As shown, in one embodiment, the card holder 221 is provided with a first magnetic member 225, which is specifically disposed on the side wall of the card holder 221 away from the control box 3; the box body 31 is provided with a second magnetic member 33 that attracts the first magnetic member 225, which is specifically disposed on the inner wall of the second box body 31B. The first magnetic member 225 and the second magnetic member 33 can both be magnets, magnets, etc. The control box 3 and the card holder 221 are detachably connected by the magnetic attraction of the first magnetic member 225 and the second magnetic member 33. Of course, in other embodiments, the control box 3 can also be connected to the card holder 221 by a detachable method such as a card-attachment.

[0046] like Figures 3 to 8 As shown, in one embodiment, the retaining ring 4 includes a first stop portion 41 and a second stop portion 42 spaced apart, and an annular portion 43 connected between the first stop portion 41 and the second stop portion 42. The first stop portion 41, the second stop portion 42, and the annular portion 43 are an integral structure, and all three are circular annular structures. The first stop portion 41 and the second stop portion 42 protrude radially outward relative to the annular portion 43. An annular groove 40 is formed between the first stop portion 41, the second stop portion 42, and the annular portion 43. The annular portion 43 is located inside the through hole 11, and the side wall of the housing 1 (specifically the front housing 10A) is sandwiched between the first stop portion 41 and the second stop portion 42, that is, the side wall of the housing 1 is stuck in the annular groove 40. At the same time, the retaining ring 4 and the housing 1 are connected and fixed by sewing; of course, in other embodiments, the retaining ring 4 and the housing 1 can also be fixed by adhesive bonding, thermal bonding, etc.

[0047] like Figures 1 to 3 and Figure 9 and Figure 10 As shown, in one embodiment, the housing 31 also contains a battery 34, which is electrically connected to the first circuit board 321. The battery 34 powers the eye massager. The housing 31 has a control button 35, which is also electrically connected to the first circuit board 321. The control button 35 controls the opening and closing of the eye massager and its operating mode. The first circuit board 321 has a charging interface 323, which is electrically connected to the first circuit board 321. A charging hole (not labeled) is provided on the housing 31 corresponding to the charging interface 323, through which the charging interface 323 protrudes, facilitating user charging of the battery 34.

[0048] In one embodiment, the electrical connection component 22 is located in the middle of the housing 1 in the left-right direction, so that when the control box 3 is connected to the electrical connection component 22, the control box 3 is also located in the middle of the housing 1 in the left-right direction.

[0049] As one implementation method, the cleaning steps for this eye massager are as follows: First, remove the control box 3 from the housing 1. Then, open the opening and closing mechanism to separate the retaining seat 221 of the inner liner assembly 2 from the retaining ring 4. Next, remove the inner liner assembly 2 through the notch to the outside of the housing 1. The housing 1, control box 3, and inner liner assembly 2 can then be deeply cleaned separately (the housing 1 can be soaked, brushed, and rubbed with cleaning agent). After cleaning, put the inner liner assembly 2 back into the housing 1 and re-engage the retaining seat 221 of the inner liner assembly 2 with the retaining ring 4. Then, close the opening and closing mechanism and reinstall the control box 3 onto the housing 1. When the control box 3 or the inner liner assembly 2 is damaged, the replacement steps for the control box 3 and the inner liner assembly 2 are similar to the above steps. The control box 3 and the inner liner assembly 2 can be replaced as a whole (without requiring the user to disassemble the control box 3 and the inner liner assembly 2 to replace the internal parts separately), thus facilitating operation.

[0050] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
