Technical Field

[0001] The utility model relates to the technical field of cosmetic spraying devices, in particular to a spraying component. Background Art

[0002] Cosmetic sprayers generally include a container, a liquid introduction tube, a valve body and a nozzle. The liquid introduction tube is arranged in the container, the valve body is movably arranged on the mouth of the container, the nozzle is arranged on the valve body, and a channel for connecting the liquid introduction tube and the nozzle is arranged in the valve body. The container is often used to contain liquid products such as toner or lotion.

[0026] Example:

[0027] See also Figure 1-Figure 4A spray assembly comprises a drainage tube 1, a valve structure 2, a nozzle 3 (aperture is 0.33mm) and a sealing cup 4; the sealing cup 4 is sealed and arranged on the mouth of a container bottle W; the container bottle W is filled with powder and gas (specifically low-boiling point gas); the drainage tube 1 is arranged in the container bottle W, a part of the valve structure 2 is arranged in the container bottle W, and the other part is arranged outside the container bottle W, the drainage tube 1 is connected to the sealing cup 4 through the valve structure 2, and is connected to the nozzle 3 obliquely arranged on the container bottle W through the valve structure 2; the valve structure 2 is a compressible and restorable structure; a valve chamber 2.1.1 is arranged on the valve structure 2, and a tail hole 2.1.2 (aperture is 0.64mm) connected to the drainage tube 1 and a first bypass hole 2.1.3 (aperture is 0.33mm) connected to the container bottle W are opened on the valve chamber 2.1.1. When the valve structure 2 is pressed, the valve structure 2 is compressed into the container bottle W, so that the gas in the drainage tube 1 is reduced; after the pressing is completed, during the recovery process of the valve structure 2, the powder in the container bottle W is compressed by the gas in the container bottle W into the drainage tube 1 and is sprayed out through the tail hole 2.1.2, the valve chamber 2.1.1 and the nozzle 3; and the first bypass hole 2.1.3 is provided to facilitate the valve chamber 2.1.1 and the gas in the drainage tube 1 to always be connected with the gas in the bottle, ensuring that the decompression extraction and spraying operation of the powder is completed smoothly.

[0028] See also Figure 1-Figure 3The valve structure 2 includes a valve body 2.1, an annular elastic member 2.2 (specifically a spring) and a valve stem 2.3; the valve body 2.1 is arranged in the container bottle W and connected to the drainage tube 1; the valve chamber 2.1.1 is arranged in the valve body 2.1; a part of the valve stem 2.3 is arranged in the valve chamber 2.1.1, and the other part passes through the sealing cup 4 and is arranged outside the container bottle W; a mounting hole for the valve stem 2.3 to slide through is arranged on the sealing cup 4; a through hole 2.3.1 connected to the valve chamber 2.1.1 and the nozzle 3 is provided in the valve stem 2.3 to facilitate the smooth extraction of powder; a The second side hole 2.3.2 (aperture is 0.46mm) is convenient for extracting gas from the top of the bottle and better mixing powder; the annular elastic member 2.2 is arranged in the valve chamber 2.1.1, one end of which is connected to the inner wall of the valve chamber 2.1.1, and the other end is sleeved on the valve stem 2.3 and connected to the outer wall of the valve stem 2.3; when the annular elastic member 2.2 is in a compressed state, the valve stem 2.3 contacts the tail hole 2.1.2 on the valve chamber 2.1.1 to ensure that the powder is sprayed out in a pressed state; when the annular elastic member 2.2 is in a free extension state, the valve stem 2.3 is separated from the tail hole 2.1.2 on the valve chamber 2.1.1 to ensure that the powder is not sprayed out in a non-pressed state. The combination of the annular elastic member 2.2 and the valve stem 2.3 can realize the compressibility and recovery operation of the valve structure 2.

[0029] See also Figure 3 A first annular limit platform 2.1.4 connected to the tail hole 2.1.2 is provided in the valve chamber 2.1.1 near one end of the drainage tube 1. The inner diameter of the first annular limit platform 2.1.4 is larger than the inner diameter of the tail hole 2.1.2, so that the powder can be smoothly extracted. The inner diameter of the first annular limit platform 2.1.4 is larger than the minimum outer diameter of the valve stem 2.3, so that when the annular elastic member 2.2 is in a compressed state, the valve stem 2.3 can smoothly contact the tail hole 2.1.2 on the valve chamber 2.1.1 and directly extract the powder from the valve chamber 2.1.1.

[0030] See also Figure 4 A second annular limit platform 2.3.3 is provided on the outer wall of the valve stem 2.3, and the outer diameter of the second annular limit platform 2.3.3 is larger than the inner diameter of the mounting hole to prevent the valve stem 2.3 from being separated from the mounting hole during the restoration process.

[0031] See also Figure 1 One end of the annular elastic member 2.2 is connected to the first annular limit platform 2.1.4, and the other end is connected to the second annular limit platform 2.3.3, which facilitates the limiting installation of the annular elastic member 2.2 and provides a stable elastic force to the valve stem 2.3.

[0032] See also Figure 1-Figure 2 The spray assembly further comprises an inner gasket 5, which is arranged at the connection between the valve stem 2.3 and the mounting hole to ensure a sealing effect.

[0033] See also Figure 4 An annular groove is provided on the outer wall of the valve stem 2.3, and the annular groove is provided on the side of the second annular limit platform 2.3.3 away from the annular elastic member 2.2, so that when the valve stem 2.3 is not pressed (i.e. the annular elastic member 2.2 is in a freely extended state), the inner gasket 5 is accommodated in the annular groove to achieve a better sealing effect.

[0034] See also Figure 4 The second bypass hole 2.3.2 is arranged on the annular groove, so that when the annular elastic member 2.2 is in a non-pressed state (ie, the annular elastic member 2.2 is in a freely extended state), the inner gasket 5 can seal the second bypass hole 2.3.2 to prevent powder and gas from escaping.

[0035] See also Figure 1-Figure 2 The spray assembly further comprises an outer gasket 6, which is arranged at the connection between the sealing cup 4 and the mouth of the container bottle W to ensure a sealing effect.

[0036] The spray assembly operation process is as follows:

[0037] When the valve structure 2 is pressed, the valve structure 2 is compressed into the container bottle W, so that the gas in the drainage tube 1 is reduced; after the pressing is completed, during the recovery process of the valve structure 2, the powder in the container bottle W is compressed by the gas in the container bottle W into the drainage tube 1 and is sprayed out through the tail hole 2.1.2, the valve chamber 2.1.1 and the nozzle 3; and the first bypass hole 2.1.3 is provided to facilitate the valve chamber 2.1.1 and the gas in the drainage tube 1 to always be connected with the gas in the bottle, ensuring that the decompression extraction and spraying operation of the powder is completed smoothly.

[0038] In addition, this embodiment limits the aperture of the tail hole in the spray assembly to 0.64mm, the aperture of the first side hole to 0.33mm, the aperture of the nozzle to 0.33mm, and the aperture of the second side hole to 0.46mm, which can be combined to enable the spray assembly to gently spray powder products suitable for the face.

[0039] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
