Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a shock-absorbing and noise-reducing eye lubricator. Background Technology

[0002] With the fast pace of modern life and the widespread use of electronic devices, dry eye syndrome has become a common eye health problem. Dry eye syndrome typically manifests as dryness, stinging, or a foreign body sensation in the eyes, primarily caused by insufficient tear production or excessive tear film evaporation. To alleviate and treat these problems, various eye care devices that promote tear production have emerged on the market.

[0003] Currently, electric massagers are a common health care device. They use a built-in power source to drive a vibration device, transmitting vibrational energy to the body to achieve a massage effect. The vibration characteristics of these devices, such as frequency and amplitude, can effectively promote local blood circulation and relieve muscle tension. However, specialized devices for patients with dry eye syndrome are still relatively scarce, especially instruments that can directly promote tear secretion by stimulating specific physiological reflex mechanisms.

[0004] In the prior art, patent CN217724064U discloses a tear secretion stimulator, which is designed to enhance tear secretion by stimulating the external nasal nerve area through vibration. This device uses a vibrating head to contact the skin near the user's nasal bone and lateral nasal cartilage; the vibration energy stimulates the nasolacrimal reflex, thereby promoting tear secretion. However, during the massage process, the vibrating head may repeatedly impact the inner wall of the housing due to high-frequency vibration, resulting in significant external vibration and considerable noise, affecting the user experience.

[0005] Invention CN118662348A discloses a device for treating dry eye syndrome. The device includes a housing and: a light source assembly comprising a light source array consisting of multiple light sources; a control circuit configured to activate the light source assembly to emit light radiation onto the outer surface of one or more eyelids according to predetermined light modulation parameters, using blue-violet light of a specific wavelength for phototherapy of dry eye syndrome. The device may also include a vibrator, which, according to a control signal from the control circuit, works in conjunction with the light source assembly to massage a target area around the eyelids. The vibration frequency range of the vibrator is 30Hz to 80Hz. This invention's device primarily uses phototherapy with vibration massage as a secondary function. Its structure is relatively complex, its manufacturing cost is high, making it difficult to popularize and promote. Furthermore, it does not address the comfort of vibration massage, and is prone to noise and significant shaking during vibration operation, thus reducing the user experience.

[0006] Therefore, how to improve existing eye massage devices and vibration massage components, optimize vibration stability and massage effect to achieve efficient, convenient and personalized treatment for dry eye patients, while improving user comfort and portability, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] To address the shortcomings of the existing technology, this utility model provides a shock-absorbing and noise-reducing eye moisturizer. By optimizing the vibration structure design, the collision noise between the vibration component and the shell is reduced. While ensuring the vibration intensity, vibration stability and massage effect of the vibration massage head, it can achieve efficient, convenient and personalized treatment for dry eye patients, while effectively reducing noise and improving user comfort and portability.

[0008] This utility model provides a shock-absorbing and noise-reducing eye moisturizer, comprising: a vibration unit, a shock-absorbing unit, and a housing covering the vibration unit and the shock-absorbing unit;

[0009] The vibration unit includes a vibrating block and an eccentric motor disposed within the housing, and a vibrating massage head connected to the vibrating block and extending out of the housing;

[0010] The eccentric motor is connected to the vibrating block and drives the vibrating block and the vibrating massage head to vibrate;

[0011] The damping unit is disposed between the vibration unit and the housing.

[0012] This invention reduces the transmission of vibration generated by the vibration unit to the housing by setting a damping unit between the vibration unit and the housing. This effectively reduces the impact and noise generated during vibration, thus improving the vibration and noise reduction performance of the equipment.

[0013] Furthermore, the housing has a working cavity that covers the vibration unit and the shock absorption unit, and may also have a handle-like cavity or handle-like body for easy gripping. The aforementioned working cavity and handle-like cavity (or handle-like body) have an integrated streamlined structure, which is convenient for hand gripping and carrying. In addition, if the internal capacity is sufficient, the housing can also have a variety of design options, such as a structure with only the working cavity (i.e., without a separate handle or similar object), with a compact overall size. By combining this with a concave-convex housing design for easy gripping, the operator can hold the massage firmly.

[0014] Furthermore, the eccentric motor is connected to one outer wall of the vibrating block and is suspended inside the housing. This suspended structure avoids collisions between the eccentric motor and the housing, preventing severe vibrations that could reduce grip comfort. This is especially beneficial when the housing is designed as a handle or handle-shaped cavity; the eccentric motor's location within the housing, away from the gripping end of the eye massager, minimizes grip vibration and improves comfort. On the other hand, it reduces energy loss during the transmission of eccentric motor vibration, ensuring it is effectively transmitted to the vibrating block and enhancing the vibration effect.

[0015] Furthermore, the housing includes a fixed cavity for accommodating the vibrating block, and limit grooves are respectively provided on the two opposite side walls of the fixed cavity; limit posts are respectively provided on the two opposite outer walls of the vibrating block, and the limit posts are correspondingly inserted into the limit grooves.

[0016] The damping unit is disposed between the vibrating block and the fixed cavity.

[0017] Furthermore, two limiting grooves are respectively provided on the opposite sidewalls of the fixed cavity, and two limiting posts are respectively provided on the opposite outer walls of the vibrating block.

[0018] The cooperation of the limiting post and the limiting groove effectively restricts the movement of the vibrating block within the fixed cavity, ensuring the stability and precise vibration direction of the vibrating block. Simultaneously, the damping unit positioned between the vibrating block and the fixed cavity absorbs unwanted vibrations from the vibrating block impacting the fixed cavity during vibration, reducing the impact of the vibrating block on the housing during operation, effectively reducing noise, and thus improving the equipment's vibration damping and noise reduction effects and user comfort.

[0019] Based on the vibration characteristics of the eccentric motor, the vibrating block vibrates in at least a first direction (Y-axis or longitudinal) and a second direction (X-axis or transverse). Vibration in the first direction drives the vibrating massage head to extend and retract, providing primarily an impact-type massage effect to promote blood circulation. Vibration in the second direction drives the vibrating massage head to vibrate horizontally, providing a kneading-type massage effect.

[0020] Furthermore, the limiting groove on the side wall of the fixed cavity extends along the first direction. The limiting post of the vibrating block is inserted into the corresponding limiting groove. On the one hand, due to the vibration of the eccentric motor, the limiting post moves back and forth in the limiting groove along the first direction, increasing the stroke of the vibrating massage head and enhancing the massage effect. On the other hand, the highest and lowest points of the limiting groove limit the vibration amplitude of the vibrating block in the first direction, preventing the vibrating block and its vibrating massage head from being shaken out and damaged, and also preventing the bottom of the vibrating block from hitting the bottom of the fixed cavity, thus increasing the vibration or noise of the housing.

[0021] Furthermore, the shock-absorbing unit includes a silicone sleeve that covers the vibrating block.

[0022] As a flexible material, the silicone sleeve effectively absorbs and buffers the vibrations generated by the vibratory block, reducing the energy directly transmitted to the housing, thereby effectively reducing noise and minimizing the impact of vibration on other components. The elasticity of silicone also provides additional stability, keeping the vibratory block stable during operation, further enhancing the device's vibration damping and noise reduction effects and user comfort.

[0023] Furthermore, the silicone sleeve is provided with a first through hole corresponding to the vibrating massage head, a second through hole corresponding to the eccentric motor, and a third through hole corresponding to the limiting post of the vibrating block.

[0024] Furthermore, a guide post is provided at the bottom of the silicone sleeve, and a spring is sleeved on the guide post and abuts against the bottom wall of the fixed cavity.

[0025] The user presses down on the vibrating massage head with their muscles, compressing the spring and generating greater tension, thus increasing the output of massage force and achieving the effect of adjusting the massage intensity. Secondly, the spring's elasticity helps the vibrating massage head smoothly follow the skin's surface, avoiding discomfort caused by uneven pressure and increasing massage comfort.

[0026] Furthermore, the shock-absorbing and noise-reducing eye moisturizer also includes an electronic control unit, which includes a button disposed on the outer surface of the housing and a circuit board fixed inside the housing and connected to the button; the outer surface of the button may optionally be provided with a light-transmitting element.

[0027] This shock-absorbing and noise-reducing eye moisturizer can be powered by batteries or by connecting to an external power source. Battery-powered devices can be equipped with replaceable batteries, rechargeable batteries, or rechargeable batteries fixed in the casing. For portability and ease of operation, battery power is preferred.

[0028] Specifically, the circuit board is connected to the button, the eccentric motor and the battery. The vibration intensity and mode are adjusted by controlling the output frequency of the eccentric motor. The battery supplies power to the eccentric motor in a controlled manner.

[0029] A light-transmitting element is set on the outer surface of the button, which can emit different colors of light according to different settings of the eye moisturizer, making it convenient for users to identify and adjust.

[0030] Furthermore, the shock-absorbing and noise-reducing eye moisturizer also includes a protective cover for protecting the vibrating massage head, which is detachably installed at the opening where the vibrating massage head extends out of the housing.

[0031] The protective cover can be designed in various ways to facilitate easy disassembly and maintain an aesthetically pleasing appearance, such as using a cap-shaped design, a cartoon design, or an irregular three-dimensional shape. It can be made of transparent or opaque material and can be joined using snap-fit ​​or plug-in methods for easy disassembly. When the shock-absorbing and noise-reducing eye massager is not in use, the protective cover is installed at the opening in the housing to surround and protect the vibrating massage head, preventing wear and damage. It also prevents dust, water, and other impurities from entering the housing through the gap between the opening and the vibrating massage head, which could lead to contamination or short circuits. To use the device, simply remove the protective cover. Furthermore, to prevent loss, a flexible connecting cable is preferably used to movably connect the protective cover to the housing, ensuring it does not affect or interfere with the instrument's use and is less likely to be lost.

[0032] Furthermore, the housing includes an upper housing and a lower housing, which are connected by snap-fit, screw fixing, fitting connection, thermal riveting and / or adhesive bonding.

[0033] This utility model has at least the following beneficial effects:

[0034] (1) By setting a damping unit between the vibration unit and the housing, the vibration is concentrated in the vibration massage head, ensuring the vibration intensity, vibration stability and massage effect of the vibration massage head. In particular, by using a silicone sleeve to cover the vibration block, the damping unit effectively absorbs and buffers the vibration generated by the vibration block, reducing the vibration energy transmitted to the housing, thereby significantly reducing the collision noise between the vibration and the housing.

[0035] (2) The spring design in this utility model allows users to adjust the massage intensity by pressing down on the vibrating massage head with their muscles. Compressing the spring generates greater tension, thereby increasing the output of massage force and achieving a personalized massage experience. In addition, the elasticity of the spring helps the vibrating massage head follow the skin surface smoothly, avoiding discomfort caused by uneven pressure, ensuring a more comfortable and safe massage process, and meeting the needs of different users.
