Description

Technical Field

[0001] The utility model belongs to the technical field of atomization, and in particular relates to a liquid outlet nozzle and an atomization device. Background Art

[0002] In the fields of medical treatment, aromatherapy and electronic cigarettes, an atomizer is needed to atomize the liquid. Taking aromatherapy as an example, essential oil is stored in a liquid bottle, and the liquid bottle is connected to the atomizer. The atomizer works to extract the essential oil in the liquid bottle and spray it out in the form of atomization. When the essential oil is atomized, a high-pressure airflow is sprayed to the liquid outlet of the liquid outlet nozzle. The high-pressure airflow flows through the liquid outlet, so that a negative pressure is formed at the liquid outlet. The negative pressure extracts the essential oil in the liquid bottle, and the essential oil is sprayed from the liquid outlet and mixed with the high-pressure airflow, thereby achieving the purpose of atomizing the essential oil. At present, the high-pressure airflow passes through the liquid outlet, and the high-pressure airflow is relatively dispersed, so that the essential oil cannot be fully dispersed, and the atomization effect is not ideal. Utility Model Content

[0003] In view of this, the utility model provides a liquid outlet nozzle and an atomizing device, which can limit the flow direction of the high-pressure airflow and prevent the high-pressure airflow from dispersing, so that the liquid can be fully atomized and the atomized droplets are finer.

[0004] The technical solution adopted by the utility model is:

[0005] A liquid outlet nozzle, used for an atomizing device, comprises a body, a plug-in port opening downwardly formed on the body, a liquid outlet hole provided on the top wall of the body, the lower end of the liquid outlet hole being communicated with the plug-in port, a drainage groove is further provided on the outer side of the body, the drainage groove is inclinedly arranged, one end of the drainage groove passes through the side wall of the body, and the other end of the drainage groove passes through the top wall, the drainage groove avoids the liquid outlet hole, the boundary line between the groove bottom of the drainage groove and the top wall is a first boundary line, and a preset distance is left between the first boundary line and the liquid outlet hole.

[0006] Preferably, a boundary line between the bottom of the drainage groove and the side wall is a second boundary line, and the second boundary line is located below the middle of the side wall.

[0007] Preferably, the angle between the plane where the bottom of the drainage groove is located and the horizontal plane is 30°-60°.

[0008] Preferably, the preset spacing is no greater than 3 mm.

[0009] Preferably, the inner diameter of the liquid outlet hole gradually decreases from bottom to top.

[0010] The utility model also relates to an atomizing device, comprising a first shell, a lower connecting piece, an airway and the aforementioned liquid outlet nozzle, wherein a first cavity with an opening facing downward is formed in the first shell, the liquid outlet nozzle is connected to the upper wall of the first shell, and a liquid outlet hole of the liquid outlet nozzle is connected to the first cavity;

[0011] The lower connecting member includes a connecting plate and a connecting side wall, the connecting side wall is connected to the lower side of the connecting plate, the connecting side wall encloses a second cavity with an opening facing downward, the inner wall of the connecting side wall is provided with a threaded structure for connecting a liquid bottle, the lower connecting member is connected to the lower side of the first shell, the connecting plate closes the downward opening of the first cavity from the lower side, and a through hole is provided on the connecting plate, so that the first cavity and the second cavity are connected through the through hole;

[0015] Beneficial effects of the utility model:

[0016] The liquid outlet nozzle provided by the utility model is applied to an atomizing device. When the atomizing device is working, a high-pressure airflow is sprayed toward the drainage groove on the liquid outlet nozzle. A groove wall is formed on the drainage groove. The groove wall can limit the flow of the high-pressure airflow, so that the high-pressure airflow can only flow along the extension direction of the drainage groove, thereby avoiding the dispersion of the high-pressure airflow. The high-pressure airflow flows toward the first boundary line, and the first boundary line is basically adjacent to the liquid outlet hole, so that the high-pressure airflow flows through the liquid outlet hole, thereby forming a negative pressure at the liquid outlet hole, thereby sucking out the liquid. The liquid is sprayed from the liquid outlet hole and mixed with the high-pressure airflow. Since the high-pressure airflow basically does not disperse, the liquid can be fully atomized to form finer atomized droplets, thereby improving the atomization effect of the atomizing device.

[0031] See also Figure 1-Figure 4 The utility model provides a liquid outlet nozzle, which is applied to an atomization device. The atomization device can be applied to medical treatment, aromatherapy and electronic cigarettes. For example, in medical treatment, it is used as a medical atomizer, and the liquid bottle 5 is filled with liquid medicine. In aromatherapy, it is used as an aromatherapy spray, and the liquid bottle 5 is filled with essential oil. In electronic cigarettes, the liquid bottle 5 is filled with tobacco oil.

[0032] The liquid outlet nozzle includes a main body 1, on which is formed an insertion port opening facing downward, a liquid outlet hole 14 is provided on the top wall 12 of the main body 1, and the lower end of the liquid outlet hole 14 is connected to the insertion port, and a drainage groove 13 is also provided on the outer side of the main body 1, and the drainage groove 13 is inclined. One end of the drainage groove 13 passes through the side wall 11 of the main body 1, and the other end of the drainage groove 13 passes through the top wall 12, and the drainage groove 13 avoids the liquid outlet hole 14. The boundary line between the bottom of the drainage groove 13 and the top wall 12 is the first boundary line 15, and a preset distance is left between the first boundary line 15 and the liquid outlet hole 14.

[0033] The body 1 includes a top wall 12 and a side wall 11. The side wall 11 is in a circular shape and is connected to the lower side of the top wall 12, so that the body 1 forms an insertion port with an opening facing downward. A liquid outlet 14 is provided on the top wall 12. The liquid outlet 14 passes through the top wall 12 and is basically located at the center of the top wall 12. The liquid outlet 14 is connected to the insertion port.

[0034] For ease of understanding, the liquid outlet nozzle is applied to the atomization device for explanation. The atomization device includes a first shell 2, a lower connecting member 3, an air passage 4 and a liquid outlet nozzle. A first cavity 21 with an opening facing downward is formed in the first shell 2. The liquid outlet nozzle is connected to the upper wall of the first shell 2, and the liquid outlet hole 14 of the liquid outlet nozzle is connected to the first cavity 21.

[0035] The lower connecting member 3 includes a connecting plate 31 and a connecting side wall 32, the connecting side wall 32 is connected to the lower side of the connecting plate 31, the connecting side wall 32 surrounds a second cavity 33 with an opening facing downward, and a threaded structure for connecting a liquid bottle 5 is provided on the inner wall of the connecting side wall 32. The lower connecting member 3 is connected to the lower side of the first shell 2, the connecting plate 31 closes the downward opening of the first cavity 21 from the lower side, and a through hole is provided on the connecting plate 31, so that the first cavity 21 is connected to the second cavity 33 through the through hole.

[0036] The air channel 4 is located outside the first shell 2 . The air channel 4 has an air port 41 . The air port 41 faces the drainage groove 13 .

[0037] When the high-pressure airflow is sprayed toward the drainage groove 13, a groove wall is formed on the drainage groove 13, and the groove wall can limit the flow of the high-pressure airflow (in the width direction), so that the high-pressure airflow can only flow along the extension direction of the drainage groove 13, thereby avoiding the dispersion of the high-pressure airflow, and the high-pressure airflow flows to the first boundary line 15, and the first boundary line 15 is basically adjacent to the liquid outlet 14, so that the high-pressure airflow flows through the liquid outlet 14, thereby forming a negative pressure at the liquid outlet 14, thereby sucking out the liquid, and the liquid is sprayed from the liquid outlet 14 to mix with the high-pressure airflow. Since the high-pressure airflow basically does not disperse, the liquid can be fully atomized to form finer atomized droplets, thereby improving the atomization effect of the atomization device.

[0038] In addition, the cross-section of the side wall can be circular (the outer peripheral surface of the side wall is curved) or square (part of the outer peripheral surface of the side wall is flat); the bottom of the drainage groove 3 can be flat or curved, as long as the two ends of the bottom of the groove are connected to the side wall and the top wall respectively.

[0039] Moreover, the distance between the two groove walls of the drainage groove 3 can be constant or variable. For example, from bottom to top, the distance between the two groove walls gradually decreases (the change can be linear or nonlinear), thereby compressing the high-pressure airflow in the relative direction of the two groove walls, thereby accelerating the flow rate of the high-pressure airflow.

[0040] A boundary line between the bottom of the drainage groove 13 and the side wall 11 is a second boundary line 16 , and the second boundary line 16 is located below the middle of the side wall 11 .

[0041] The drainage groove 13 has a certain size in the height direction, which facilitates the high-pressure airflow to be blown into the drainage groove 13 .

[0042] The angle between the plane where the bottom of the drainage groove 13 is located and the horizontal plane is 30°-60°, for example, 30°, 40°, 50° or 60°.

[0043] The high-pressure airflow is basically blown toward the drainage groove 13 in a horizontal manner, and the drainage groove 13 is inclined, so as to guide the high-pressure airflow to flow obliquely upward, so that the high-pressure airflow passes through the liquid outlet 14. Moreover, the angle between the bottom of the drainage groove 13 and the horizontal plane (the top surface of the top wall 12 is also a horizontal plane) is 30°-60°, so that the drainage groove 13 has a certain length in the height direction, so that the high-pressure airflow can all reach the bottom of the drainage groove 13, and the bottom of the drainage groove 13 is inclined, so that it can flow upward along the bottom of the drainage groove 13, basically enabling all the high-pressure airflow to pass through the liquid outlet 14, and the liquid sprayed from the liquid outlet 14 contacts with all the high-pressure airflow, so that efficient atomization of the liquid can be achieved.

[0044] The angle between the groove bottom and the horizontal plane is controlled between 30° and 60°, so as to minimize the kinetic energy loss caused by the high-pressure airflow contacting the groove bottom and ensure that sufficient negative pressure can be generated when the high-pressure airflow reaches the liquid outlet 14 to suck out the liquid.

[0045] The preset spacing is no greater than 3 mm (for example, 1 mm, 2 mm or 3 mm), so that the high-pressure airflow can immediately reach the liquid outlet 14 when it flows out of the first boundary line 15, ensuring that the high-pressure airflow will basically not disperse through the liquid outlet 14, thereby ensuring the atomization effect on the liquid.

[0046] See also Figure 4 From bottom to top, the inner diameter of the liquid outlet hole 14 gradually decreases, so that the speed of the liquid passing through the liquid outlet hole 14 increases, the atomization effect of the liquid and the high-speed airflow is improved, and the atomized droplets are finer.

[0047] The utility model also provides an atomization device, including a first shell 2, a lower connecting piece 3, an airway 4 and the aforementioned liquid outlet nozzle, a first cavity 21 with an opening facing downward is formed in the first shell 2, the liquid outlet nozzle is connected to the upper wall of the first shell 2, and the liquid outlet hole 14 of the liquid outlet nozzle is connected to the first cavity 21.

[0048] The lower connecting member 3 includes a connecting plate 31 and a connecting side wall 32, the connecting side wall 32 is connected to the lower side of the connecting plate 31, the connecting side wall 32 surrounds a second cavity 33 with an opening facing downward, and a threaded structure for connecting a liquid bottle 5 is provided on the inner wall of the connecting side wall 32. The lower connecting member 3 is connected to the lower side of the first shell 2, the connecting plate 31 closes the downward opening of the first cavity 21 from the lower side, and a through hole is provided on the connecting plate 31, so that the first cavity 21 is connected to the second cavity 33 through the through hole.

[0049] The air channel 4 is located outside the first shell 2 . The air channel 4 has an air port 41 . The air port 41 faces the drainage groove 13 .

[0050] The specific working process of the atomization device has been described in the previous article and will not be repeated here.

[0051] The inner diameter of the air port 41 gradually decreases as it moves toward the guide groove 13 , thereby increasing the velocity of the high-pressure airflow ejected from the air port 4131 .

[0052] The ratio of the minimum inner diameter of the air port 41 to the width of the drainage groove 13 is (1:3)-(1:6), so that the high-pressure airflow ejected from the air port 41 basically enters the drainage groove 13, reducing the probability of the high-pressure airflow entering outside the drainage groove 13, thereby ensuring that the high-pressure airflow acts on the liquid outlet 14, and improving the atomization effect on the liquid.

[0053] It should be understood that the above-mentioned embodiments are merely illustrative and not restrictive. Without departing from the basic principles of the present invention, various obvious or equivalent modifications or substitutions that can be made by technicians in this field to the above details will be included in the scope of the claims of the present invention.
