Description

Technical Field

[0001] This utility model relates to the field of aerosol nozzle technology, specifically an eye protection spray nozzle. Background Technology

[0002] With people's excessive reliance on electronic products today, eye strain is becoming increasingly common, and using various eye care products to relieve eye discomfort has become a common practice. Traditional eye care products are mostly stored in liquid containers, requiring the container to touch the eyes and then be instilled with the eye drops. However, this method has significant drawbacks: the container is easily contaminated with bacteria when in contact with the eyes, and repeated use may lead to cross-infection; at the same time, once the eye drops are opened, they are exposed to air, and the active ingredients are prone to evaporation or deterioration, making it impossible to preserve the remaining liquid, which affects the effectiveness and easily leads to waste.

[0003] To address this, the industry has developed spray-type eye protection devices, such as the atomizing eyewash device disclosed in Chinese Patent CN202321328649.7. However, these devices suffer from problems such as difficulty in controlling the spray volume and the tendency to spray excessively, which not only wastes eyewash solution but also makes it difficult for the telescopic tube to evenly distribute the liquid to the eyes, resulting in poor eye protection effects. Therefore, further improvements are necessary. Utility Model Content

[0004] The present invention aims to provide an eye protection spray nozzle to overcome the shortcomings of the prior art.

[0005] An eye spray head designed for this purpose includes a connector, which has an assembly port and a connection port. The connector is assembled to a pressure tank containing eye drops through the assembly port. A connector is connected to the connection port, and a soft eye mask is provided on the connector. A pressing element is also movably provided on the connector. The lower end of the pressing element is connected to the valve body of the pressure tank. An atomizing nozzle is provided on the pressing element facing the connection port.

[0006] The connecting seat is through-type at both ends, with the assembly port formed at the lower end of the connecting seat and an assembly snap-fit ​​part provided thereon. The connecting seat can be detachably snapped onto the pressure tank through the assembly snap-fit ​​part.

[0007] The connecting seat has a longitudinal guide at its center, and the pressing member moves longitudinally on the longitudinal guide. The pressing member extends toward the pressure tank with a connecting post, and the connecting post has a connecting hole that communicates with the valve body of the pressure tank.

[0008] The connecting post is provided with a pressing element at its center, and reinforcing ribs extend from the outer side of the connecting post toward the outer wall of the pressing element.

[0009] The outer wall of the pressing component is also provided with reinforcing ribs, and the reinforcing ribs are connected to the reinforcing ribs.

[0010] The atomizing nozzle is connected to the side of the connecting column. The atomizing nozzle has a protrusion facing the connection port. A positioning groove is provided on the longitudinal guide part. The protrusion is longitudinally positioned and movable on the positioning groove.

[0011] The connection port is formed on one side of the connector and is provided with a connection snap-fit ​​part. The connector is provided with a connection snap-fit ​​mating part, and the connection snap-fit ​​mating part and the connection snap-fit ​​part can be detachably snap-fitted together.

[0012] The connection port is also provided with a connection anti-mistake part, and the connector is provided with a connection anti-mistake mating part. The connection anti-mistake mating part and the connection anti-mistake part cooperate to achieve a mistake-proof connection. The connection port is provided with a mistake-proof mark corresponding to the connection anti-mistake part, or the connector is provided with a mistake-proof mark corresponding to the connection anti-mistake mating part.

[0013] The tops of the connecting seat and the pressing member are inclined away from the connecting member, and the top of the pressing member is also arc-shaped and has a pressing anti-slip texture.

[0014] The soft eye mask has an arc-shaped edging extending from its outer edge. The front of the arc-shaped edging is elliptical, and the upper and lower parts of the middle are recessed towards the connecting seat.

[0015] This invention connects the spray head to a pressure tank storing eye drops via an assembly port. A press-fit component connects to the pressure tank's valve body, controlling the spray volume per application through the pressing stroke. The press-fit component is positioned towards the connection port, allowing the atomized eye drops to be sprayed directly onto the soft eye mask. This design overcomes the shortcomings of existing technologies, such as difficulty in controlling the spray volume and the risk of excessive spraying, effectively conserving eye drops.

[0022] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] See Figures 1-6 This eye spray head includes a connector 1, which has an assembly port 1.1 and a connection port 1.2. The connector 1 is assembled onto a pressure tank containing eye drops through the assembly port 1.1. A connector 2 is connected to the connection port 1.2, and a soft eye mask body 3 is provided on the connector 2. A pressing member 4 is also movably provided on the connector 1. The lower end of the pressing member 4 is connected to the valve body of the pressure tank. An atomizing nozzle 4.1 is provided on the pressing member 4 facing the connection port 1.2.

[0025] In this embodiment, the spray head is used in conjunction with the pressure tank storing eye drops through the assembly port 1.1. At the same time, the press part 4 is connected to the valve body of the pressure tank. The amount of sprayed per burst is controlled by the pressing stroke. Moreover, the press part 4 is set towards the connection port 1.2 at 4.1, so that the eye drops are atomized and sprayed directly towards the soft eye mask body 3. This not only allows the user to control the amount of sprayed per burst by pressing the stroke, but also solves the defects of the prior art that the amount of spray is difficult to control and easy to spray too much, effectively saving eye drops. The sprayed atomized eye drops can also act evenly and fully on the eyes, improving the eye protection effect. In addition, the soft eye mask body 3 on the connection part 2 fits flexibly with the skin around the eyes during use, preventing spray leakage and improving the comfort and safety of use.

[0026] The connecting seat 1 is designed with a through-type configuration at both ends, facilitating the connection and installation of the internal structure. An assembly port 1.1 is formed at the lower end of the connecting seat 1, and its inner wall is provided with an assembly latching part 1.3 (e.g., an annular groove or snap-fit ​​structure). Through this assembly latching part 1.3, the connecting seat 1 can be securely and detachably latched onto the opening of a pressure canister (not shown in the figure, belonging to the prior art of pressure spray cans) containing eye drops, enabling quick installation and replacement, and improving the product's versatility and ease of use.

[0027] At the center of the connecting seat 1, a longitudinal guide portion 1.4 is provided. The longitudinal guide portion 1.4 is preferably a cylindrical part that runs through the upper and lower ends of the connecting seat 1, with a smooth inner wall or a guide rib, for guiding the pressing member 4 to perform stable and smooth longitudinal (i.e., perpendicular to the direction of the pressure tank opening) reciprocating motion.

[0028] A connection port 1.2 is formed on one side of the connector 1 for connecting the connector 2. A connection latching part 1.6 (e.g., a slot) is provided on the inner or outer wall of the connection port 1.2. To ensure that the connector 2 can be assembled in the only correct direction and to avoid reverse assembly, a connection anti-misalignment part 1.7 is also provided on the connection port 1.2. Correspondingly, a connection anti-misalignment mating part 2.2 is provided on the connector 2. The connection anti-misalignment mating part 2.2 mates with the connection anti-misalignment part 1.7 to achieve a mistake-proof connection. Furthermore, to provide intuitive assembly guidance for the user and further prevent misoperation, a mistake-proof marking 1.8 is provided on the connection port 1.2 corresponding to the connection anti-misalignment part 1.7, or on the connector 2 corresponding to the connection anti-misalignment mating part 2.2. Specifically, in this embodiment, a mistake-proof marking 1.8 is provided on the connector 2 at the position corresponding to the connection anti-misalignment mating part 2.2 to indicate the correct assembly direction of the connector 2.

[0029] The presser 4 is longitudinally movable on the longitudinal guide portion 1.4. A connecting post 4.2 extends from the presser 4 toward the pressure tank. This connecting post 4.2 is preferably located at the center of the presser 4, and its lower end has a connecting hole 4.3. When the spray head is installed on the pressure tank, the connecting hole 4.3 at the lower end of the connecting post 4.2 communicates with the outlet of the pressure tank's valve body. When the user presses down on the presser 4, it will open the valve body of the pressure tank, allowing the pressurized eye drops inside the tank to enter the connecting post 4.2 through the connecting hole 4.3.

[0030] To ensure the structural strength of the connecting column 4.2 and prevent it from bending or breaking under repeated pressure, several radially evenly distributed reinforcing ribs 4.4 extend from the outer side of the connecting column 4.2 toward the outer wall of the pressing member 4. In addition, longitudinal reinforcing ribs 4.5 are also provided on the outer wall of the pressing member 4. These reinforcing ribs 4.5 are connected to the reinforcing ribs 4.4 as a whole, forming a high-strength support, which significantly improves the overall mechanical strength and durability of the pressing member 4.

[0031] The pressing component 4 is provided with an atomizing nozzle 4.1 facing the connection port 1.2. The atomizing nozzle 4.1 is connected to the internal flow channel on the side of the connecting column 4.2. The eye protection liquid is delivered to the atomizing nozzle 4.1 through the connecting column 4.2. The atomizing nozzle 4.1 has a fine atomizing channel (such as a vortex chamber or a micro-spray hole) inside, which can break the liquid into fine droplets before spraying it out.

[0032] To achieve precise spray direction guidance and prevent the pressing part 4 from rotating within the guide section, a protrusion 4.6 is integrally formed on the outer side of the atomizing nozzle 4.1 towards the connecting port 1.2, and a longitudinally extending positioning groove 1.5 is correspondingly provided on the inner wall of the longitudinal guide section 1.4. The protrusion 4.6 is embedded in the positioning groove 1.5 and can slide up and down within it, thereby ensuring that the atomizing nozzle 4.1 is always precisely aligned with the connecting port 1.2 and the interior of the subsequent soft goggle body 3, ensuring the accuracy of the spray path, and preventing the part from deflecting during the pressing process, resulting in a better operating feel.

[0033] To conform to ergonomics and facilitate user pressing, the tops of both the connector 1 and the pressing element 4 are designed to tilt away from the connector 2 (i.e., towards the user). The top of the pressing element 4 further extends in an arc shape to perfectly fit the fingertip, and its surface is provided with anti-slip texture. Figure 4 .7 (such as grid patterns, striped protrusions, etc.) increases the coefficient of friction, allowing for stable force application even when the user's hands are wet, effectively preventing slippage and improving the safety and convenience of operation.

[0034] One end of the connector 2 is provided with a connecting snap-fit ​​part 2.1 (e.g., a snap hook), which is used to detachably snap-fit ​​with the connecting snap-fit ​​part 1.6 on the connector 1, so as to realize the quick connection and separation of the two, and facilitate cleaning or replacement.

[0035] The other end of the connector 2 is fixed with a soft eye mask body 3. The soft eye mask body 3 is preferably made of safe, soft, and elastic materials such as silicone or TPE, and is fixed to the connector 2 by means of covering, bonding, or integral molding. The outer edge of the soft eye mask body 3 extends outward to form a curved rim 3.1. The front outline of this curved rim 3.1 is elliptical, conforming to the contour of the eye socket around the human eye. Specifically, the upper and lower parts of its middle section are designed to be recessed towards the connector 1 (i.e., towards the face), forming a curve that better fits the bridge of the nose and cheekbone area. When the user places the soft eye mask body 3 over their eyes, the soft curved rim 3.1 forms a flexible, sealed fit with the skin around the eyes. This effectively prevents the atomized eye drops from leaking out, improving liquid utilization and maintaining cleanliness; it also avoids the pressure of hard materials on the skin, greatly improving comfort and safety during use.

[0036] In use, connect the connector 1 to the pressure tank containing the eye drops via the assembly port 1.1. Connect the connector 2 (with the soft eye mask 3) to the connector port 1.2 of the connector 1 in the correct foolproof orientation. Hold the pressure tank and gently place the soft eye mask 3 around the closed area of ​​the eyes. Then press the press button 4 with your finger. The press button 4 moves down along the guide part 1.4, opening the pressure tank valve through the connecting column 4.2. Under the pressure inside the tank, the eye drops are sprayed out from the atomizing nozzle 4.1 through the connecting column 4.2, forming fine droplets that are directly sprayed into the closed or semi-closed space formed by the soft eye mask 3 and the eyes and surrounding skin, so that the atomized eye drops are evenly adhered to the eyes and surrounding skin.
