Abstract
Description
Technical Field
[0001] This utility model relates to the field of atomization technology, and in particular to an atomizing core. Background Technology
[0002] Currently, most essential oil atomizing nozzles on the market use two-fluid internal extrusion atomizing coils. Internal extrusion atomizing nozzles are noisy and have low atomization efficiency, requiring two or more components, making manufacturing difficult and demanding high assembly precision. In contrast, in open-type atomizing coils, the liquid outlet faces the high-speed gas outlet. The liquid is dispersed under the impact of the gas, thus achieving atomization. This structure is effective for low-viscosity liquids like water, but less effective for high-viscosity liquids like essential oils, and also produces more noise.
[0003] CN 215460527 U discloses an atomizing core, including a core body. The core body has an essential oil channel and a gas channel. The essential oil channel includes an outlet end and an inlet end, and the gas channel includes an air outlet end and an air inlet end. The outlet end and the air outlet end intersect at an angle, with the outlet end located vertically above and at the vertical center of the air outlet end. This atomizing core relies on the air outlet end to blow airflow above it. However, in this way, the airflow blows directly towards the outlet end, making the essential oil at the outlet end susceptible to airflow interference, resulting in relatively loud noise and a relatively mediocre atomization effect.
[0004] The technical problem that this invention aims to solve is: how to improve the atomization effect of the atomizing core and reduce noise. Utility Model Content
[0005] The main purpose of this utility model is to provide an atomizing core in which the side wall of the first protrusion near the air outlet is designed as a first inclined surface and a second inclined surface connected sequentially along the liquid outlet direction. The high-speed airflow blown out of the air outlet will blow onto the first inclined surface, causing the high-speed airflow to be divided, and then the airflow direction is adjusted by the second inclined surface, thereby improving the atomization effect and reducing noise.
[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0007] An atomizing core includes a body, the body having a first protrusion having a liquid outlet hole; the body having an air outlet hole; the axis of the air outlet hole being perpendicular to the axis of the liquid outlet hole; a second protrusion blocking more than half of the end face area of the air outlet hole; the side wall of the first protrusion near the air outlet hole being a first inclined surface and a second inclined surface connected sequentially along the liquid outlet direction; the slope angle of the first inclined surface being greater than the slope angle of the second inclined surface.
[0008] Compared with existing technologies, this solution has the following advantages:
[0009] In one type of atomizing core, the sidewall of the first protrusion is designed with a first inclined surface and a second inclined surface connected sequentially along the liquid outlet direction. Under the obstruction of the first protrusion, part of the high-speed airflow from the air outlet blows upwards towards the liquid outlet, creating a vacuum near the liquid outlet, thereby causing the essential oil to be sprayed out from the liquid outlet. Secondly, the remaining high-speed airflow flows along the first and second inclined surfaces, and under the action of the first and second inclined surfaces, changes the direction of the high-speed airflow, driving the essential oil to move in a directional manner.
[0010] By setting the first and second inclined planes, the speed of the high-speed airflow can be slowed down, allowing more airflow to circulate back into the air duct of the air outlet, increasing the air output of the air outlet, and further enhancing the flow of the high-speed airflow along the liquid outlet, thereby enhancing the atomization ability of the high-speed airflow on the essential oil. In addition, the degree of outward diffusion of the high-speed airflow is reduced, avoiding the noise caused by the scattered atomization of the essential oil. Attached Figure Description

Detailed Implementation
[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application implemented as described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0018] Example 1
[0019] refer to Figure 1-3 An atomizing core includes a body 1, the body 1 having a first protrusion 2, the first protrusion 2 having a liquid outlet 21; the body 1 having an air outlet 11; the axis of the air outlet 11 being perpendicular to the axis of the liquid outlet 21; the first protrusion 2 blocking more than half of the end face area of the air outlet 11; the side wall of the first protrusion 2 near the air outlet 11 being a first inclined surface 22 and a second inclined surface 23 connected sequentially along the liquid outlet direction; the slope angle of the first inclined surface 22 being greater than the slope angle of the second inclined surface 23.
[0020] In this embodiment, the working process of this atomizing core is as follows: the external air pump introduces high-speed airflow into the air outlet 11. The high-speed airflow is ejected from the air outlet 11 and impacts the first protrusion 2, so that a part of the high-speed airflow passes above the liquid outlet 21, carrying away the air above the liquid outlet 21 and forming a negative pressure, thereby causing the essential oil in the liquid outlet 21 to be ejected. The subsequent high-speed airflow will mix and cut the essential oil to form atomized essential oil and spray it outward. The remaining high-speed airflow will flow along the first inclined surface 22 and the second inclined surface 23 and then flow back to the vicinity of the air outlet 11 and blow it together with the high-speed airflow ejected from the air outlet 11 towards the top of the liquid outlet 21, thereby increasing the overall air output, making the essential oil more evenly atomized, and improving the atomization effect.
[0021] It should be noted that the combination of the first inclined surface 22 and the second inclined surface 23 can slow down the airflow along the first inclined surface 22 and the second inclined surface 23, allowing it to mix better with the high-speed airflow ejected from the air outlet 11. Secondly, by using the first inclined surface 22 and the second inclined surface 23, the direction of airflow can be better adjusted, avoiding the situation where the airflow between the first protrusion 2 and the air outlet 11 cancels each other out when the airflow flows back through the gap between the first protrusion 2 and the air outlet 11. This allows more high-speed airflow to be blown towards the liquid outlet 21, reducing the diffusion of high-speed airflow in other directions, thereby improving the atomization effect and reducing noise.
[0022] Preferably, the slope angle of the first inclined plane 22 is 36° to 56°; the slope angle of the second inclined plane 23 is 26° to 46°.
[0023] In this embodiment, the slope angle of the first inclined plane 22 is 46°, and the slope angle of the second inclined plane 23 is 36°.
[0024] Preferably, the second inclined surface 23 and the end face of the first protrusion 2 form a boundary line 24; the boundary line 24 is located on the side of the axis of the liquid outlet 21 close to the air outlet 11, and the boundary line 24 is tangent to or intersects with the end face of the liquid outlet 21.
[0025] In this embodiment, the boundary line 24 is tangent to or intersects with the end face of the liquid outlet 21. This allows a portion of the high-speed airflow to immediately pass over the liquid outlet 21 when it impacts the first protrusion 2, enabling the essential oil in the liquid outlet 21 to be ejected more quickly. Specifically, when the boundary line 24 is tangent to the end face of the liquid outlet 21, the liquid outlet 21 forms a notch with the second inclined surface 23. When the high-speed airflow impacts the first protrusion 2, a portion of the high-speed airflow will blow along the notch towards the liquid outlet 21, resulting in a more uniform mixing of the essential oil in the liquid outlet 21 with the high-speed airflow, thus improving its atomization effect.
[0026] Preferably, the body 1 is provided with an air intake channel 12; the air intake channel 12 is connected to the air outlet 11; the diameter of the air intake channel 12 is larger than the diameter of the air outlet 11.
[0027] In this embodiment, the external air pump is connected to the air intake channel 12. The external air pump blows the airflow into the air intake channel 12 and then ejects it through the air outlet 11. Since the diameter of the air intake channel 12 is larger than the diameter of the air outlet 11, the airflow enters from the large diameter to the small diameter, and the airflow velocity increases, thereby forming a high-speed airflow.
[0028] Preferably, the body 1 is provided with an essential oil channel 13; the essential oil channel 13 is connected to the liquid outlet 21; the diameter of the essential oil channel 13 is larger than the diameter of the liquid outlet 21.
[0029] In this embodiment, the essential oil fills the essential oil channel 13. After a negative pressure zone is formed above the liquid outlet 21, the essential oil is sprayed outward from the essential oil channel 13 through the liquid outlet 21. The diameter of the essential oil channel 13 is larger than the diameter of the liquid outlet 21, which can enable the essential oil to be continuously output, avoiding the essential oil from being sprayed out intermittently, which would affect the atomization effect and generate noise.
[0030] Preferably, the end face of the first boss 2 is a third inclined surface 25.
[0031] In this embodiment, the third inclined surface 25 can guide the high-speed airflow after it passes through the liquid outlet 21, preventing the high-speed airflow from spreading outward, thereby better achieving directional spraying.
[0032] Preferably, the distance between the highest point of the first boss 2 and the air outlet 11 is 1.5 to 3.5 mm.
[0033] In this embodiment, the distance between the highest point of the first protrusion 2 and the air outlet 11 is preferably 2.5 mm. By controlling the distance between the highest point of the first protrusion 2 and the air outlet 11, and in conjunction with the first inclined surface 22 and the second inclined surface 23, the airflow flowing along the first inclined surface 22 and the second inclined surface 23 can be better returned to the vicinity of the air outlet 11, avoiding the generation of vortices in the gap between the first protrusion 2 and the air outlet 11, and causing the airflow between the first protrusion 2 and the air outlet 11 to cancel each other out, thereby reducing the atomization effect.
[0034] Preferably, the body 1 is provided with a second protrusion 3; the second protrusion 3 is located on the side of the first protrusion 2 near the air outlet 11; the air outlet 11 passes through the end face of the second protrusion 3 and communicates with the outside.
[0035] In this embodiment, the addition of a second protrusion 3 to the air outlet 11 can reduce the probability of essential oil sprayed from the liquid outlet 21 adhering to the vicinity of the air outlet 11, and prevent essential oil from entering the air outlet channel from the air outlet 11, thus affecting the next air spray.
[0036] Preferably, the sidewall of the second boss 3 is a fourth inclined surface 31.
[0037] In this embodiment, by setting the fourth inclined surface 31, the probability of essential oil adhering to the vent 11 is further avoided, allowing the essential oil to flow to the outside along the fourth inclined surface 31.
[0038] Example 2
[0039] refer to Figure 4 Compared with Example 1, the difference in this embodiment is that the slope angle of the first inclined surface 22 is 36°, the slope angle of the second inclined surface 23 is 26°, and the boundary line 24 intersects with the end face of the liquid outlet 21.
[0040] The slope angle of the first inclined surface 22 is set to 36°, and the slope angle of the second inclined surface 23 is set to 26°. After the airflow ejected from the air outlet 11 hits the first protrusion 2, part of the airflow flows sequentially through the second inclined surface 23 and the first inclined surface 22. The airflow can then flow back to the vicinity of the air outlet 11, mix with the airflow ejected subsequently from the air outlet 11, and blow together towards the liquid outlet 21. This improves the negative pressure effect near the liquid outlet 21 and prevents the airflow from forming vortices between the first protrusion 2 and the air outlet 11, thus preventing the airflow from canceling each other out. Secondly, after the airflow is mixed, it enhances the directional flow of the airflow in the horizontal direction, reduces the airflow from diffusing in other directions, and the airflow cuts and mixes the essential oil more evenly, avoiding the formation of large essential oil droplets, improving the atomization effect and reducing noise.
[0041] Example 3
[0042] refer to Figure 5Compared with Example 1, the difference in this embodiment is that the slope angle of the first inclined surface 22 is 56°, the slope angle of the second inclined surface 23 is 46°, and the boundary line 24 is tangent to the end face of the liquid outlet 21.
[0043] The slope angle of the first inclined surface 22 is set to 56°, and the slope angle of the second inclined surface 23 is set to 46°. This can improve the negative pressure effect near the liquid outlet 21 and prevent the airflow from forming vortices between the first protrusion 2 and the air outlet 11, thus causing the airflows to cancel each other out. Secondly, it enhances the directional flow of airflow in the horizontal direction, reduces the diffusion of airflow in other directions, improves the atomization effect, and reduces noise.
