Description

Technical Field

[0001] This utility model belongs to the field of spray structure technology, specifically relating to an adjustable spray structure. Background Technology

[0002] Existing spray structures mostly use vertically positioned atomizers with a fixed spray direction, which limits the water mist distribution range. Especially when it is necessary to evenly cover the surface parallel to the spray direction with water mist, the parabolic trajectory is often formed due to gravity, resulting in uneven spray. In addition, adjusting the spray direction in traditional structures requires replacing the atomizer or relying on external equipment, which not only increases costs but also reduces the flexibility of use. Although some designs attempt to expand the coverage by increasing the power of the atomizer, the energy consumption is high and liquid waste is easy to occur. Another common problem is the insufficient contact stability between the water absorption component and the atomizer. Liquid transmission is easily affected by vibration or tilting, causing spray interruption. In the current technology, there is a lack of a simple, low-cost solution that can flexibly adjust the spray direction, which makes it difficult to meet the needs of diverse application scenarios. Therefore, there is an urgent need for a spray structure that can ensure spray uniformity and allow for angle adjustment through simple operation. Utility Model Content

Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0036] like Figure 1-3 As shown, this utility model provides an adjustable spray structure, including a housing 1. The housing 1 includes an upper shell 11 and a lower shell 12, which together form a receiving cavity 13. An atomizing component 2 is provided inside the receiving cavity 13. The atomizing component 2 includes a water tank component 21 and an atomizer 22. An absorbent cotton swab 23 is provided between the water tank component 21 and the atomizer 22. The upper shell 11 includes a first upper shell 111 and a second upper shell 112. The receiving cavity 13 includes a first mounting cavity 131 corresponding to the first upper shell 111 and a second mounting cavity 132 corresponding to the second upper shell 112. The first mounting cavity 131 accommodates the water tank component 21 and the absorbent cotton swab 23, and the second mounting cavity 132 accommodates the atomizer 22.

[0037] The lower shell 12 has a first connecting part 133 on the inner peripheral wall of the second mounting cavity 132. The first connecting part 133 is a protrusion extending from both sides of the central axis L of the shell 1 toward the center in the direction of the interior of the second mounting cavity 132. The water tank component 21 has a second connecting part 212 corresponding to the first connecting part 133. The second connecting part 212 is a concave shape corresponding to the protrusion. The water tank component 21 is fixed in the second mounting cavity 132 by the second connecting part 212 and the first connecting part 133, which prevents the water tank component 21 from shaking and causing leakage, and effectively improves the installation stability and durability of the water tank component 21.

[0038] Specifically, a through hole is provided between the first mounting cavity 131 and the second mounting cavity 132. One end of the absorbent cotton swab 23 passes through the through hole and contacts the atomizer 22. That is, one end of the absorbent cotton swab 23 is connected to the water tank component 21 and directly contacts the liquid therein, while the other end directly contacts the atomizer 22. It is worth noting that the first mounting cavity 131 is a closed space. This design ensures that even if the water tank leaks, the liquid will not flow to the atomizer 22 or other components in the second mounting cavity 132 and cause damage. The radius of the through hole 14 is smaller than the radius of the absorbent cotton swab 23, and the two are interference-fitted, so that water from the water tank will not enter the second mounting cavity 132 through the through hole 14. Instead, the liquid flows from the water tank through capillary action. The water tank is transported to the atomizer 22, and the high-frequency resonance of the atomizer 22 breaks down the liquid water molecules to produce a naturally drifting water mist, forming ultrafine particles to achieve a highly efficient spraying effect. The atomizer 22 is usually a thin sheet with two parallel surfaces. One surface is used to spray water mist, and the other surface is used to fully contact the absorbent cotton swab 23 and is designated as the contact surface 3. That is, the contact surface 3 and the spraying surface of the atomizer 22 are always parallel. It is worth noting that the tail shape of the absorbent cotton swab 23 is not fixed, but can be arbitrarily adjusted to maximize the area of ​​the contact surface 3, such as adjusting it to an inclined surface. In this application, the central axis P of the absorbent cotton swab 23 and the contact surface 3 of the atomizer 22 are inclined.

[0039] In most commercially available spray structures, the atomizer 22 is positioned perpendicular to the spray direction. Furthermore, some spray structures require the atomizer 22 to be used with a heated comb or straightener. In practical applications, the atomizer 22 needs to spray water mist onto one of the working surfaces 6 of the comb or straightener to achieve a cooling function. This working surface 6 is usually parallel to the spray direction. The water mist falls onto the working surface 6 under gravity, following a parabolic trajectory. The best effect of this process is that the atomizer 22 can evenly spray water mist onto the working surface 6. However, in ordinary spray structures, the atomizer 22 is positioned perpendicular to the spray direction. Without adjusting the spray intensity, the atomizer would be difficult to achieve the above-mentioned effect. If the spray intensity of the atomizer is adjusted, the atomizer needs to be replaced or the control device needs to be adjusted, which increases the cost. To solve this problem, the contact surface 3 of the absorbent cotton swab 23 and the atomizer 22 in this application is set at an angle, forming an angle A with the central axis P of the absorbent cotton swab 23. The angle A needs to be adjusted adaptively according to the spray intensity of the atomizer 22 and the size of the area of ​​the working surface 6. By simply adjusting the angle A, the atomizer 22 can evenly spray water mist onto the working surface 6.

[0040] Specifically, such as Figure 4-5As shown, in one embodiment of this utility model, under normal circumstances, the central axis P of the absorbent cotton swab 23 is parallel to the central axis L of the housing 1. At this time, the angle A formed by the contact surface 3 of the atomizer 22 and the axis P or L has been set. However, when the comb or straightener needs to be replaced and the angle A needs to be adjusted again, the atomizer 22 needs to be adjusted, which is a very cumbersome process. In order to simplify the process, the contact surface 3 can be adjusted indirectly by adjusting the absorbent cotton swab 23. Specifically, the central axis P of the absorbent cotton swab 23 is adjusted to form an angle with the central axis L of the housing 1, which is set as angle B. The angle B ranges from 0 to 45 degrees. Since the absorbent cotton swab 23 is always in full contact with the atomizer 22, when the central axis P and the central axis L form the angle B and change, the angle formed by the contact surface 3 and the central axis L of the housing 1 will also change to form angle C. The angle A is equal to the angle B plus the angle C.

[0041] Specifically, such as Figure 6-7 As shown, in one embodiment of this utility model, a guide bracket 4 is provided between the absorbent cotton swab 23 and the water tank component 21. The guide bracket 4 has a groove 43 for fixing the absorbent cotton swab 23. The groove 43 is cylindrical in shape and matches the absorbent cotton swab 23. Simultaneously, the tail end of the absorbent cotton swab 23 near the water tank component 21 is provided with a first inclined surface 231 or a first slot 232. A second groove 43 is provided within the groove 43 that cooperates with the first inclined surface 231 or the first slot 232. The inclined surface 41 or the second slot 42 is provided to form a snap-fit ​​structure. This structural design allows the absorbent cotton swab 23 and the inclined surface or slot therein to be firmly fixed in the guide bracket 4, maintaining the stability of liquid water transmission through capillary action. On the other hand, when it is necessary to replace the absorbent cotton swab 23, it can be separated from the guide bracket 4 along the axis P, which is very convenient. In another embodiment, the tail of the absorbent cotton swab 23 can also be a conventional cylinder, which can achieve similar effects.

[0042] Specifically, such as Figure 8As shown, in practical applications, the spray structure will be connected to different products, such as combs or hair straighteners. Different products will have different spray angle requirements for their atomizers 22. To change the spray angle, the tilt angle of the atomizer 22 must be changed. One end of the absorbent cotton swab 23 is also inclined and always in contact with the atomizer 22, forming the contact surface 3. That is, changing the angle C formed by the contact surface 3 and the central axis L of the housing 1 can change the spray angle of the atomizer 22. To meet this technical requirement, the tilt angle of the groove 43 is changed, that is, the slope of the second inclined surface 41 is reduced. Since the groove 43 is adapted to one end of the absorbent cotton swab 23, when the... When the guide bracket 4 and one end of the absorbent cotton swab 23 abut against each other, the absorbent cotton swab 23 tilts together with the groove 43, the first inclined surface 231 and the second inclined surface 41 are in contact, and the slope of the first inclined surface 231 will also decrease. This causes the end of the absorbent cotton swab 23 near the guide bracket 4 to move down, while the end near the atomizer 22 and the atomizer 22 rise together. The included angle C becomes smaller, thereby changing the spray angle of the atomizer 22. The inclination degree of the groove 43 inside the guide bracket 4 is specially set according to different products, such as combs or hair straighteners, during production. Different products only need to produce different guide brackets 4, and other components can be produced on the same production line, which greatly reduces production costs.

[0043] Furthermore, such as Figure 9-10 As shown, the guide bracket 4 is provided with at least one through hole 44 or through groove 45. The through hole 44 is circular in shape, and its two ends are respectively connected to the water tank component 21 and the groove 43, so that the absorbent cotton swab 23 provided in the groove 43 can contact the water tank component 21 through the through hole 44 and effectively absorb water over the maximum range. Preferably, the number of through holes 44 is 3. In some other embodiments, the through holes 44 can also be replaced by mesh, which can achieve the same effect.

[0044] Specifically, such as Figure 11As shown, in the prior art, due to differences in size and workmanship, and the possibility of shaking, knocking, or dropping during use, the absorbent cotton swab 23 and atomizer 22 in a conventional spray structure are prone to loosening or even gaps. This results in poor contact between the absorbent cotton swab 23 and atomizer 22, leading to poor, unstable, or absent atomization effects from the atomizer 22, severely impacting the user experience. To effectively solve this technical problem, in one embodiment of this utility model, the water tank component 21 contacts the guide bracket 4... The end is provided with a spring-loaded part 51, and a spring 5 is provided between the spring-loaded part 51 and the guide bracket 4. The spring-loaded part 51 is a protrusion extending along the axis L towards the guide bracket 4. One end of the spring 5 is sleeved on the outer periphery of the protrusion and forms a stable snap-fit ​​structure with it. That is, one end of the spring 5 is fixed on the water tank component 21, and the other end is in elastic contact with the guide bracket 4. Through its elasticity, it applies an elastic force close to the absorbent cotton swab 23 to the guide bracket 4 to push the absorbent cotton swab 23, ensuring that the guide bracket 4 and the absorbent cotton swab 23 are always fully pressed and abutted.

[0045] Meanwhile, by combining the first inclined surface 231 or the first slot 232 with the second inclined surface 41 or the second slot 42, and under the spring pressure of the spring 5, the absorbent cotton swab 23 always maintains full and stable contact with the atomizer 22. This effectively avoids the problem of poor contact or loosening between the absorbent cotton swab 23 and the atomizer 22 due to shaking, knocking, dropping, or differences in workmanship. It further solves the problems of poor, unstable, and disappearing atomization effect of the atomizer 22, thereby enabling the atomizer 22 to maintain an effective, continuous, and stable atomization effect, thus further improving the user experience. In other embodiments, the spring 5 can be replaced with any elastic material to achieve similar effects.

[0046] Furthermore, such as Figure 12 As shown, the guide bracket 4 has a limiting protrusion 46 on its outer side, and the upper shell 11 or lower shell 12 has a concave-convex block that engages with it. The limiting protrusion 46 extends perpendicular to the spring compression direction of the spring 5 and is used to limit the spring compression of the spring 5 on the guide bracket 4, preventing the guide bracket 4 from excessively squeezing the absorbent cotton swab 23 and causing it to deform. In other embodiments, the number of limiting protrusions 46 can be one or more, which can achieve the same effect.

[0047] Furthermore, such as Figure 12-13As shown, the water tank component 21 has a sliding part 213 at one end near the guide bracket 4, and the guide bracket 4 is slidably connected to the sliding part 213. At the same time, the outer side of the guide bracket 4 is also provided with at least two guide strips 47 parallel to the spring compression direction of the spring 5. The water tank component 21 is provided with guide grooves 211 corresponding to the guide strips 47. This structural design ensures that the movement direction of the guide bracket 4 when subjected to spring compression is always along the axis L, avoiding deviation from the trajectory and loosening or deformation of the absorbent cotton swab 23. In other embodiments, the guide grooves 211 are provided on the outer side of the guide bracket 4, and the guide strips 47 are provided on the water tank component 21, which can achieve the same effect. In other embodiments, the number of guide strips 47 can be one or more, which can also achieve the same effect.

[0048] The following is a detailed explanation of the working principle of this utility model:

[0049] Liquid is stored or flows through the water tank component 21 and continuously delivered to the atomizer 22 via the absorbent cotton swab 23 through capillary action. The atomizer 22 disperses liquid water molecules into ultrafine particles through high-frequency resonance, forming a naturally drifting water mist. The key is that the contact surface 3 between the absorbent cotton swab 23 and the atomizer 22 is set at an angle, forming an adjustable angle. This design allows the spray direction of the atomizer 22 to be flexibly adjusted according to actual needs without replacing the atomizer or making complex structural modifications. When the area or position of the action surface 6 (such as the cooling surface of a comb or hair straightener) changes, only the tilt angle of the absorbent cotton swab 23 needs to be adjusted to change the tilt angle of the contact surface of the atomizer 22, thereby optimizing the coverage trajectory of the water mist and making it evenly distributed in the target area. In addition, the elastic cooperation between the guide bracket 4 and the water tank component 21 ensures that the absorbent cotton swab 23 is always in close contact with the atomizer 22, avoiding interruption of liquid transmission. At the same time, the design of the spring 5 and the guide strip 47 limits the offset of the bracket.

[0050] The innovation of this utility model lies in the following: The adjustable-angle contact surface design significantly improves the adaptability and uniformity of the spray structure. Compared to traditional vertical atomizers, this design allows for indirect changes in the spray direction of the atomizer by adjusting the tilt angle of the absorbent cotton swab. Precise control of the water mist coverage area can be achieved without replacing parts or complex operations. This improvement effectively solves the problems of fixed spray direction and uneven coverage in existing technologies, making it particularly suitable for scenarios requiring uniform spraying of water mist onto a parallel working surface (such as cooling hair styling tools). Simultaneously, the coordinated design of the guide bracket and elastic components ensures stable contact between the absorbent cotton swab and the atomizer, preventing interruption of liquid transmission and improving reliability. Furthermore, the modular structure simplifies assembly and maintenance processes, reducing production costs. The overall solution balances high-efficiency spray performance with flexibility and economy, making it widely applicable in various fields such as home appliances, medical, and beauty. The snap-fit ​​connection between the first and second connecting parts also effectively secures the water tank component to the housing.
