Description

Technical Field

[0001] The utility model relates to an eye care spray cap device.

Background Art

[0002] Most of the surface of the eyes is exposed to the outside world, making them vulnerable to environmental stimuli, bacteria, dust, etc. When there is a large amount of eye discharge, or eyelid skin allergy and eye fat granule formation caused by makeup, the eyes' own cleaning and protection functions may be insufficient to eliminate the impact.

[0003] In order to clean and care for the eyes or assist in drug administration treatment, some auxiliary eye cup devices for spray bottles have emerged on the market. As disclosed in the Chinese utility model patent with the application number 201922384995.7, it includes a spray head and an eye cup. The socket at the lower end of the spray head is connected to the spray bottle; the pressing plate at the upper end of the spray head is in contact with the nozzle of the spray bottle. The connecting part of the eye cup is circular and gradually expands into an elliptical fitting part; the connecting part of the eye cup is rotatably connected to the spray head, and the nozzle direction of the spray bottle points to the fitting part of the eye cup. When the spray head is sleeved on the spray bottle, the convex edge of the eye cup is gently pressed on the eye socket of a person to directly contact the skin of the person, and then the pressing plate is pressed down to eject the content of the spray bottle. Although this auxiliary eye cup device can be used for cleaning and caring for the eyes or assisting in drug administration treatment, there are still defects. Since the spray nozzle for the liquid to be sprayed in a mist shape on the nozzle is generally inserted into the nozzle, it may fly off during the spraying process. In this way, the spray nozzle is likely to pass through the connecting part and the fitting part to injure the eyes, causing unnecessary damage and greatly affecting the user experience.

[0004] Therefore, the present utility model is precisely produced based on the above deficiencies.

Specific Embodiment

[0026] The present utility model will be further described below with reference to the accompanying drawings:

[0027] As Figures 1 to 5 shown, an eye care spray cap device applicable to an aerosol bottle includes a spray base 1 that can be installed on the aerosol bottle. A pressing nozzle 2 for driving the aerosol valve of the aerosol bottle to open is slidably arranged up and down in the spray base 1. An liquid outlet channel 21 for communicating with the aerosol valve to allow the liquid in the aerosol bottle to flow out is arranged on the pressing nozzle 2, and a spray nozzle 3 for communicating with the liquid outlet channel 21 to spray the liquid in a mist shape is arranged. A hollow guiding body 4 is arranged on the spray base 1 in the spraying direction of the mist-shaped liquid of the spray nozzle 3. One end of the guiding body 4 is provided with a spray inlet 41 for allowing the mist-shaped liquid to be sprayed from the spray nozzle 3 into the guiding body 4, and the other end of the guiding body 4 is provided with a spray outlet 42 that can be attached to the skin around the human eye and for outputting the mist-shaped liquid in the guiding body 4 to the human eye. A blocking portion 43 for preventing the spray nozzle 3 from passing through the spray inlet 41 when the spray nozzle falls off is arranged at the spray inlet 41. As Figure 5 shown, before use, the present spray cap device needs to be installed on the aerosol bottle 6 so that the liquid outlet channel 21 is connected to the valve rod of the aerosol valve. The outer edge of the spray outlet 42 is arranged in a shape that fits the eye socket. During use, the spray outlet 42 is attached to the skin around the human eye. Pressing the pressing nozzle 2 at the top can drive the valve rod to open the aerosol valve, so that the liquid inside the aerosol bottle reaches the spray nozzle 3 through the liquid outlet channel 21 and then is sprayed in a mist shape from the spray inlet 41 to the spray outlet 42. During this process, even if the spray nozzle accidentally flies off during use, the blocking portion can prevent the spray nozzle from passing through the spray inlet and entering the guiding body, thereby eliminating the risk of the spray nozzle flying off and injuring the eyes. The overall structure is simple and more safe and reliable.

[0028] Specifically, the blocking portion 43 is the opening edge of the spray inlet 41, and the width of the spray inlet 41 is smaller than the diameter of the spray nozzle 3. In this way, when the spray nozzle flies off, the spray nozzle will also be blocked by the opening edge of the spray inlet 41 and cannot pass through the spray inlet 41.

[0029] Specifically, the spray inlet 41 is a vertically extending waist-shaped hole, and the length of the waist-shaped hole is greater than the diameter of the spray nozzle 3. When the pressing nozzle 2 at the top is pressed, the spray nozzle 3 also moves downward along with the pressing nozzle 2. During this process, the mist-like liquid ejected from the spray nozzle 3 can always pass through the waist-shaped hole.

[0030] As Figure 3 shown, inside the guiding body 4, an inner ring 44 extending towards the spray outlet 42 is provided outside the spray inlet 41. The inner ring 44 and the inner wall of the guiding body 4 enclose a liquid storage tank 45 that can store the liquid flowing back from the inner wall of the guiding body 4 towards the spray inlet 41. By adding the design of the liquid storage tank on the guiding body, when part of the liquid flows back from the inner wall of the guiding body towards the spray inlet, the liquid will flow into the liquid storage tank and be stored by the liquid storage tank, avoiding the situation that the flowing-back liquid enters the spray seat from the spray inlet and causing liquid leakage at the connection between the spray seat and the aerosol bottle, thus improving the user's pleasant experience.

[0031] Specifically, the guiding body 4 includes a connection head 46 with one end detachably connected to the spray seat 1 and the other end open, and an eye cup 47 detachably connected to the open end of the connection head 46. The spray outlet 42 is provided on the eye cup 47, and the spray inlet 41 and the inner ring 44 are provided on the bottom wall of the connection head 46. The eye cup 47 includes a round tube end connected to the connection head 46 and a contact end in a gradually changing flat trumpet shape, and the whole can be made of soft rubber to ensure comfortable use and fit the contour of the eye socket.

[0032] Further, an installation cavity 11 communicating with the spray nozzle 3 is provided on the spray seat 1. Both ends of the connection head 46 are respectively provided with a first insertion part 461 with one end inserted into the installation cavity 11 and a second insertion part 462 with one end inserted into the eye cup 47. A guiding and positioning device 5 for guiding the spray inlet 41 to be aligned with the spray nozzle 3 when the first insertion part 461 is inserted into the installation cavity 11 is provided between the first insertion part 461 and the installation cavity 11.

[0033] Specifically, the guiding and positioning device 5 includes a guiding slot 51 provided on the inner wall of the installation cavity 11 and a guiding block 52 provided on the outer wall of the first insertion part 461 and sliding along the guiding slot 51 when the first insertion part 461 is inserted into the installation cavity 11. When the first insertion part 461 is inserted into the installation cavity 11, the guiding block 52 and the guiding slot 51 play a guiding role in the insertion of the first insertion part 461, and can keep the waist-shaped hole vertically extended without dislocation to ensure unobstructed liquid ejection.

[0034] Further, a strip groove 111 is provided on the inner wall of the installation cavity 11, and a rib 463 that is snapped into the strip groove 111 after the first insertion part 461 is inserted into the installation cavity 11 is provided on the outer wall of the first insertion part 461, so as to ensure stable and reliable insertion of the connection head and the spray seat and prevent it from falling off during use.

[0035] In the present utility model, a sliding cavity 12 for the up-and-down sliding of the pressing nozzle 2 is provided on the spray base 1. A positioning step 13 is provided in the sliding cavity 12. The upper end of the pressing nozzle 2 is provided with a pressing surface 22 that abuts against the positioning step 13 after the pressing nozzle 2 slides downward. The upper end of the sliding cavity 12 is higher than the pressing surface 22 of the pressing nozzle 2, and the pressing surface is not easily touched accidentally, so that the self-spray problem can be avoided when the package is slightly pressed or impacted during transportation.

[0036] In the present utility model, a U-shaped hole 14 that opens downward and communicates the sliding cavity 12 with the installation cavity 11 is provided on the cavity wall of the sliding cavity 12. The pressing nozzle 2 is provided with a nozzle installation part 23 whose one end extends into the U-shaped hole 14 and slides up and down along the U-shaped hole 14. In this way, when the pressing nozzle 2 moves upward along the sliding cavity 12, the nozzle installation part 23 will finally abut against the inner wall of the inverted U-shaped hole, effectively preventing the pressing nozzle 2 from being disengaged from the spray base 1. Specifically, the spray nozzle 3 is inserted into the nozzle installation part 23.
