A hand-held scalp treatment spray bottle

Abstract

The utility model discloses a handheld scalp nursing spray bottle, including bottle body, bottle lid, pressure air bag, hose joint and flat nozzle, the bottle body top is equipped with the bottle lid, the outlet end of bottle lid is provided with flat nozzle, and the inlet end is connected with pressure air bag through hose joint, the hose joint has a bending portion, and the bending angle of bending portion is 120 to 150. The hose joint with specific bending angle and flat nozzle are innovatively combined, and the efficient and cooperative fluid conveying system is formed. The bending portion makes the hose be able to be naturally attached to the palm force trajectory, forms the smooth mechanical transmission path when extruding pressure air bag, and effectively converts the hand force into stable liquid flow power. The flat nozzle connected with the hose can accurately convert the liquid transmitted through the hose into wide fan-shaped spray based on the flattened opening structure, which not only expands the coverage range of single spraying, but also enables the medicine liquid to be evenly attached to the scalp surface in a soft and diffuse manner. Not only the stress loss problem caused by the traditional straight pipe design is solved, but also the low-damping fluid transmission from the liquid storage cavity to the target area is realized through the geometric adaptation of nozzle form and conduit trend, which significantly improves the operation comfort and nursing effect of the user.

Description

Technical Field

[0001] This utility model relates to the field of spray bottle technology, and in particular to a handheld scalp care spray bottle. Background Technology

[0002] In daily life, scalp care is crucial for maintaining healthy hair and preventing various scalp problems. However, many scalp care products currently on the market present several inconveniences in use. Traditional scalp care spray devices often use ordinary round nozzles, which do not distribute the liquid evenly enough, easily leading to excessive or insufficient application in certain areas, resulting in unsatisfactory care effects. Furthermore, their spray direction adjustment is inflexible, requiring users to frequently adjust their hand angle or head posture, making operation cumbersome and inconvenient.

[0003] Furthermore, the existing spray system design is not scientifically sound. The hose connecting the pressure bladder and nozzle lacks an effective bending design. This makes the hose susceptible to external pressure or twisting during use, affecting the normal delivery of the liquid and causing spray interruptions or unstable flow. Moreover, the unreasonable hose layout restricts the direction and range of the spray when used at different angles, further reducing the convenience and effectiveness of scalp care and failing to meet users' needs for comprehensive and even scalp care in various scenarios. Clearly, the existing technology needs improvement. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a handheld scalp care spray bottle to solve one or more problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a handheld scalp care spray bottle, comprising a bottle body, a bottle cap, a pressure airbag, a hose connector, and a flat nozzle. The bottle body is provided with a bottle cap at the top, and the outlet end of the bottle cap is provided with a flat nozzle.

[0017] This utility model provides a handheld scalp care spray bottle. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following detailed description is provided with reference to the accompanying drawings and embodiments. In the description of this utility model, it should be understood that the terms "up," "down," "left," and "right," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description; they should not be construed as limitations on this utility model. Furthermore, the terms "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] Please see Figures 1 to 3This utility model provides a handheld scalp care spray bottle, including a bottle body 1, a bottle cap 2, a pressure airbag 3, a hose connector 4, and a flat nozzle 5. The bottle body 1 has a bottle cap 2 at its top, and the flat nozzle 5 is located at the outlet end of the bottle cap 2. The inlet end is connected to the pressure airbag 3 via the hose connector 4. The hose connector 4 has a bend 6 with a bending angle of 120° to 150°. Preferably, the bottle cap 2 is threaded to the opening at the top of the bottle body 1. The synergistic effect of the hose connector 4 and the flat nozzle 5 significantly improves the user experience and functional value of the product in terms of both ease of operation and scalp care effect. On the one hand, the bending structure of the hose connector 4 adapts to the natural posture of the hand holding the spray bottle, effectively avoiding the problem of interference between the traditional connection structure and the hand. This allows the user to maintain a comfortable and stable grip when caring for different areas of the scalp (including the back of the head, behind the ears, and other inconvenient areas), providing an operational basis for the precise positioning of the flat nozzle 5. The nozzle can be aimed at the target scalp area without frequent hand adjustments, significantly reducing the difficulty of operation. On the other hand, the bending design of the hose connector 4 ensures smooth delivery of the care solution from the pressure bag 3 to the cap 2, avoiding flow obstruction or pressure instability caused by twisting of the connection structure. The flat nozzle 5, based on this stable delivery, fully utilizes its ability to adapt its spray coverage to localized areas of the scalp and its more even liquid distribution, ensuring that the care solution evenly covers the target scalp area. This avoids the problem of missed areas caused by the dispersed spray of traditional round nozzles, and also prevents spray accumulation due to poor flow, achieving a synergistic unity of "smooth operation" and "uniform care." With this synergistic effect, users can easily complete scalp care without having to overcome additional operational interference or unstable spraying issues. This not only improves the comfort of the process but also ensures that the care solution can evenly contact the scalp, fully exerting its care effects and significantly optimizing the overall scalp care experience.

[0019] Please see Figure 3The flat nozzle 5 includes a connecting part 7 and a spraying part 8. The spraying part 8 has a transversely penetrating waist-shaped spray hole 9. The connecting part 7 is inserted into the outlet end of the bottle cap 2, and the waist-shaped spray hole 9 communicates with the interior of the bottle cap 2 through the connecting part 7. More specifically, the connecting part 7 has a circular channel, one end of which communicates with the outlet end of the bottle cap 2, and the other end communicates with the waist-shaped spray hole 9. Specifically, the medication transitions from the circular channel to the waist-shaped spray hole 9 and is sprayed out from the waist-shaped spray hole 9. This design effectively controls the spray direction and range, ensuring that the medication covers the target area in a uniform fan-shaped distribution. By adjusting the width and length of the waist-shaped spray hole 9, the matching degree between the spray angle and the coverage area can be further optimized, thereby adapting to the specific needs of different scalp areas. In addition, the edges of the flat nozzle 5 are polished to avoid the risk of accidental scratches to users caused by sharp parts. The spray part 8 is made of a corrosion-resistant and anti-aging polymer material, which can maintain stable performance and extend service life when in contact with various care solutions for a long time.

[0020] Optionally, a sealing sleeve and a connecting tube 10 are also included. The outlet end of the bottle cap 2 is connected to one end of the connecting tube 10, and the other end of the connecting tube 10 is fitted with one end of the sealing sleeve. The other end of the sealing sleeve is fitted onto the outside of the connecting part 7. The sealing sleeve is made of soft and highly elastic silicone material, which can fit tightly against the outer wall of the connecting part 7, effectively preventing leakage of the agent during spraying. To ensure a firm connection and easy disassembly, the inner wall of the connecting tube 10 is designed with a threaded structure that mates with the external thread of the outlet end of the bottle cap 2. In addition, the end of the sealing sleeve may also have an annular protrusion, which strengthens the connection between the sealing sleeve and the connecting tube 10 or the connecting part 7. In actual use, the annular protrusion of the sealing sleeve can provide additional friction to ensure that it remains stable on the outside of the connecting part 7, and is not easy to fall off even during frequent operation or movement. The threaded structure of the connecting tube 10 is precision machined, which not only ensures a tight fit with the outlet end of the bottle cap 2, but also maintains good sealing performance after multiple disassemblies and reassemblies. To further enhance the reliability of the overall structure, the inner wall of the sealing sleeve is designed with a fine anti-slip texture. This texture can enhance the fit with the connection part 7 without affecting the ease of installation.

[0021] In this embodiment, a negative pressure tube 11 is integrally formed on the bottle cap 2. Both ends of the negative pressure tube 11 are connected to a connecting tube 10 and a hose connector 4, respectively. An air blowing tube 12 is also connected to the negative pressure tube 11. One end of the air blowing tube 12 communicates with the negative pressure tube 11, and the other end extends into the bottle body 1 and downwards vertically. The specific usage process is as follows: When spraying the pesticide, the user presses the nozzle to create negative pressure inside the bottle 1. The pesticide flows through the negative pressure tube 11 into the connecting tube 10 and is then evenly sprayed out from the nozzle. The air blowing tube 12 is designed to increase the air pressure inside the bottle 1, allowing the pesticide to be smoothly expelled from the bottle 1, thus ensuring the continuity and stability of the spraying process. In actual operation, the position and angle of the air blowing tube 12 have been tested to ensure that it can efficiently inject air into the bottle 1 without affecting the flow of the pesticide. In addition, the connection between the negative pressure tube 11, the connecting tube 10, and the hose connector 4 adopts a seamless connection design, avoiding liquid retention problems caused by uneven interfaces. At the same time, the length of the extension of the air blowing tube 12 inside the bottle 1 has been optimized to minimize pesticide residue and improve the utilization rate of the pesticide in the bottle. When using bottles 1 with different heights, the length of the air blowing tube 12 can be appropriately increased or decreased.

[0022] The pressure airbag 3 is spherical or ellipsoidal. More specifically, the pressure airbag 3 is made of elastic silicone material, and the pressure airbag 3 is detachably connected to the hose connector 4. The spherical or ellipsoidal design allows it to better fit the palm during use, providing a comfortable pressing experience.

[0023] In summary, this handheld scalp care spray bottle, through its rational structural combination, provides a superior user experience for scalp care. The combination of the bottle body 1 and the cap 2 ensures overall grip stability, facilitating flexible operation during care. The connection between the pressure bladder 3 and the hose connector 4 ensures stable delivery of the care solution, guaranteeing smooth operation. The flat nozzle 5 at the outlet end of the cap 2 allows the care solution to better conform to the scalp surface during spraying, contributing to a suitable coverage effect and meeting the liquid distribution requirements of scalp care. The bend 6 on the hose connector 4 allows for flexible adjustment of the nozzle's spray direction, enabling users to easily adjust their holding posture according to different scalp care areas, reducing operational limitations and further enhancing comfort and convenience during use, adapting to diverse daily scalp care scenarios. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial applicability.

[0024] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
