Description

Technical Field

[0001] The utility model relates to the field of atomization equipment, in particular to an atomization core structure and an atomization head using the atomization core. Background Art

[0002] The existing atomization equipment is provided with an air pump, an essential oil bottle and an atomization head, and an atomization core is also provided in the atomization head. A pair of air outlet holes and liquid outlet holes whose central axes form an angle with each other are generally provided on the atomization core. The air outlet hole is connected to the outlet of the air pump through the air channel, and the liquid outlet hole is connected to the liquid suction tube in the essential oil bottle through the liquid channel. After the airflow is ejected from the air outlet hole, negative pressure is generated nearby, and the essential oil in the essential oil bottle is sucked out from the liquid outlet hole. Under the impact of the airflow, mist droplets are formed and discharged through the mist outlet on the atomization head to form a fragrant mist.

[0003] In order to ensure that sufficient negative pressure can be formed near the liquid outlet, the cross-sectional area of ​​the general air outlet is smaller than that of the gas channel, and the cross-sectional area of ​​the liquid outlet is also smaller than that of the liquid channel. Limited by the size of the air outlet, although the outlet flow of the existing air pump is large, the outlet pressure is not high. The air output through a single air outlet on the atomization core is actually limited. In the use occasions where a large amount of spray is required, such as hotel halls, large conference rooms and other large environments, or when used in the fresh air duct of the air conditioning system, the air outlet flow of the aroma diffuser with a single air outlet is small, and the fragrance droplets formed are small, which cannot be used in such an environment. If the problem is solved by increasing the air flow pressure, it is necessary to replace a high-power air pump, which increases the investment in the equipment, and the service life of the air pump is also limited under long-term high power; the increase in air flow will lead to an increase in resistance at the air outlet, which is easy to generate noise and affect the user experience. In addition, excessive air pressure will cause a large change in the negative pressure at the liquid outlet, and the essential oil is prone to discontinuity when being sucked out, which seriously affects the aroma diffusion effect. In addition, the existing atomizer cores that use low-pressure, high-flow air pumps have many structural components and need to be assembled before use, which increases the number of assembly steps, increases costs, and has low product consistency, which limits its use.

[0134] Example 1

[0135] See also Figure 1-3 A porous atomizer core includes an integrally formed atomizer core body 1, on which three groups of spray ports 2 are symmetrically distributed on the same horizontal plane, each group of spray ports 2 is composed of air outlet holes 3 and liquid outlet holes 4 forming an angle between the central axis, and on the atomizer core body 1, an air outlet cavity 5 connecting all the air outlet holes 3 and a liquid outlet cavity 6 connecting all the liquid outlet holes 4 are provided. On the atomizer core body 1, an air guide tube 7 and a liquid guide tube 8 protruding outward are provided, the air outlet cavity 5 is located in the air guide tube 7, and the liquid outlet cavity 6 is located in the liquid guide tube 8. In the present embodiment, the number of the spray ports 2 is three symmetrically distributed, or it can be two or more than four, which can be selected according to the flow rate or atomization amount of the air pump used. Since the cross-section of the air outlet cavity 5 is much larger than the cross-section of the air outlet hole 3, a large amount of air can flow in the air outlet cavity 5, and each air outlet hole 3 can spray out a normal airflow without increasing the air pressure. The airflow resistance formed at the air outlet hole 3 does not increase, and the continuous airflow spraying can also form a stable negative pressure at the liquid outlet hole 4. The amount of essential oil inhaled through the liquid outlet cavity 6 is also relatively stable. The spraying can be continuous and the total amount is increased, thereby meeting the requirements of large-flow fragrance diffusion.

[0136] The air outlet cavity 5 is coaxial with the liquid outlet cavity 7, and the air outlet cavity 5 and the liquid outlet cavity 7 are respectively located at opposite ends of the atomizer core body 1 in the axial direction. The oppositely arranged air outlet cavity and liquid outlet cavity can simplify the atomizer core structure and facilitate air and liquid intake.

[0137] In this embodiment, an air guide tube 7 and a liquid guide tube 8 are provided on the atomizer core body 1, which is convenient for fixing in the atomizer head by plugging, and can also be connected in the atomizer head by threaded connection or snap connection, and a sealed connection can be used according to the use needs. The liquid guide tube 8 can also be connected to the liquid pipette of the essential oil bottle by threading. The two conduit structures can also be simplified, and only the air outlet cavity 5 and the liquid outlet cavity 6 are retained. When such an atomizer core is installed in the atomizer head, it is only necessary to ensure that the air flow channel is connected to the air outlet cavity 5, and the essential oil channel is connected to the liquid outlet cavity 6, and the structure of the atomizer core can be further simplified.

[0139] See also Figure 5-6 A porous atomizer core comprises an integrally formed atomizer core body 1, on which three groups of spray ports 2 are symmetrically distributed, each group of spray ports 2 is composed of an air outlet hole 3 and a liquid outlet hole 4 with an angle formed between the central axis, and an air outlet cavity 5 whose outlet section is connected to all the air outlet holes 3 and a liquid outlet cavity 6 whose outlet section is connected to all the liquid outlet holes 4 are provided on the atomizer core body 1. An air guide tube 7 and a liquid guide tube 8 protruding outward are provided on the atomizer core body 1, the air outlet cavity 5 is located in the air guide tube 7, and the liquid outlet cavity 6 is located in the liquid guide tube 8. The air outlet holes 3 of the three groups of spray ports 2 on the atomizer core body 1 are arranged adjacently and staggered in height, which can increase the collision of droplets and form finer droplets, which is conducive to providing an atomization effect.

[0140] In this embodiment, the air outlet cavity 5 is coaxial with the liquid outlet cavity 7, and the air outlet cavity 5 and the liquid outlet cavity 7 are respectively located at opposite ends of the atomizer core body 1 in the axial direction. The relatively arranged air outlet cavity and liquid outlet cavity can simplify the atomizer core structure and facilitate air and liquid intake. The cross-sectional area of ​​the air outlet cavity 5 is much larger than the cross-sectional area of ​​the air outlet hole 3, and a larger flow of air can pass through. Other simplified technical features are the same as those in Example 1 and are not repeated here.

[0155] In the present embodiment, the number of the spray ports 2 is three symmetrically distributed, or it can be two or more than four, which can be selected according to the flow rate or atomization amount of the air pump used. Since the cross-section of the air outlet cavity 5 is much larger than the cross-section of the air outlet hole 3, a large amount of air can flow in the air outlet cavity 5, and each air outlet hole 3 can spray out a normal airflow without increasing the air pressure. The airflow resistance formed at the air outlet hole 3 does not increase, and the continuous airflow spraying can also form a stable negative pressure at the liquid outlet hole 4. The amount of essential oil inhaled through the liquid outlet cavity 6 is also relatively stable.

When such an atomizer core is installed in the atomizer head, it is sufficient to ensure that the air flow channel is connected to the air outlet cavity 5, and the essential oil channel is connected to the liquid outlet cavity 6, and the structure of the atomizer core can be further simplified.
