Description

Technical Field

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

[0002] The existing aroma diffusion equipment is provided with an air pump, an essential oil bottle and an atomizer head. The atomizer head is provided with an atomizer core. The atomizer core is provided with an air outlet hole and a liquid outlet hole whose central axes form an angle with each other. The air outlet hole is connected to the outlet of the air pump through an air channel or an air pipe, and the liquid outlet hole is connected to the liquid suction pipe in the essential oil bottle through a liquid channel. The airflow generated by the air pump can form a negative pressure near the air outlet hole after being ejected from the air outlet hole. The essential oil in the essential oil bottle flows out from the liquid outlet hole through the liquid suction pipe, forms mist droplets after being impacted by the airflow, and forms fragrant mist after being discharged through the mist outlet on the atomizer head. In order to facilitate assembly, the atomizer core is made into an integrally formed structure, the air outlet hole and the liquid outlet hole are directly arranged on the atomizer core, an air outlet cavity connected with the air outlet hole and a liquid outlet cavity connected with the liquid outlet hole are arranged in the atomizer core body, an air outlet pipe inserted into the air outlet cavity and a liquid outlet pipe inserted into the liquid outlet cavity are arranged in the atomizer head, and the atomizer core is fixed in the atomizer head by utilizing the friction between the outer wall of the air outlet pipe and the inner wall of the air outlet cavity and between the outer wall of the liquid outlet pipe and the inner wall of the liquid outlet cavity.

[0003] Since organic solvents are often used to dissolve and mix the fragrance raw materials during the processing into essential oils, a certain amount of solvent components will inevitably remain in the finished essential oil products. Different essential oil products will also use different solvent components. The atomizer core is mostly made of a one-piece high-molecular polymer material and is within the coverage range of the sprayed essential oil droplets. The surface will be covered with essential oil components for a long time, and different degrees of swelling will inevitably occur due to the absorption of solvents, causing the overall volume of the atomizer core to swell, and the inner diameter of the liquid outlet cavity inside it will also increase accordingly, forming a gap between the inner wall of the liquid outlet tube, which is prone to essential oil leakage. The amount of essential oil flowing to the liquid outlet hole is correspondingly reduced, seriously affecting the atomization effect of the essential oil; and after the atomizer core swells, the friction between the inner wall of the cavity and the outer wall of the tube is also reduced accordingly, and the atomizer core is also easy to detach. Summary of the invention

[0004] The purpose of the utility model is to provide an atomizer core structure, which can effectively improve the connection stability of the atomizer core in the atomizer head, effectively prevent the leakage of essential oil, and stabilize the atomization effect.

[0005] Another object of the utility model is to provide an atomizer head structure, which uses the above-mentioned atomizer core structure, has reliable connection, can prevent leakage, and has a better atomization effect.

[0006] The technical solution of the utility model is: an atomizer core structure, including an atomizer core body, on which adjacent air outlet holes and liquid outlet holes are provided, and an angle is formed between the central axes of the air outlet holes and the liquid outlet holes, an air outlet cavity connected to the air outlet holes and a liquid outlet cavity connected to the liquid outlet holes are provided in the atomizer core body, and a liquid guide tube protruding outward is also provided on the atomizer core body, and the liquid outlet cavity is located in the liquid guide tube.

[0007] A protruding liquid guide tube is arranged on the atomizer core, and the liquid outlet cavity is arranged in the liquid guide tube. The connection of the atomizer core body in the atomizer head is realized by plugging the liquid guide tube. In this way, when the atomizer core swells under the action of the solvent, the size of the liquid guide tube also increases accordingly, and the matching gap between the liquid guide tube and the plug-in part of the atomizer head becomes smaller. The connection of the atomizer core in the atomizer head is tighter, and it is not easy to leak the essential oil, thereby ensuring a good atomization effect.

[0008] The atomizer core body is also provided with an outwardly protruding air guide tube, and the air outlet cavity is located in the air guide tube. The atomizer core body is further provided with a protruding air guide tube, which is connected to the atomizer head by plugging, so that the gas channel is not affected by the swelling phenomenon, thereby ensuring the stability of the gas flow and further improving the atomization effect and stability.

[0009] The central axes of the air outlet cavity and the liquid outlet cavity are parallel to each other. The central axes of the air outlet cavity and the liquid outlet cavity intersect at right angles. The gas and liquid communication mode of the atomizer core body can be conveniently arranged in the atomizer head to meet the needs of installing the atomizer core body in atomizer heads of different structures, thereby simplifying the connection between the atomizer head and the atomizer core.

[0010] Another technical solution of the utility model is: an atomizer head using the atomizer core structure as described above, wherein a gas channel connected to the outlet of the air pump is provided in the atomizer head, the gas channel is connected to the gas outlet cavity, and the liquid guide tube on the atomizer core body is connected to the liquid suction tube of the essential oil bottle by plugging. The atomizer head body is fixed in the atomizer head by plugging the liquid guide tube and the liquid suction tube. When the atomizer core body swells as a whole, the connection between the liquid guide tube and the liquid suction tube can be kept firm and stable, ensuring a stable and reliable atomization effect.

[0011] A liquid angle seat is also provided in the atomizer head, and the liquid guide tube and the liquid suction tube are connected by plugging through the liquid angle seat.

The atomizer seat is arranged in the atomizer head to facilitate modular production, and the connection of the atomizer core to the atomizer seat is achieved by inserting the liquid guide tube into the liquid inlet groove.

[0014] The central axes of the air inlet channel and the liquid inlet channel are coaxial, and the liquid inlet groove is located on one side of the liquid inlet channel. The air inlet channel and the liquid inlet channel arranged opposite to each other help simplify the structure of the atomizer seat, facilitate air and liquid intake, and the liquid inlet groove is arranged on one side to facilitate the connection of the atomizer core body to the atomizer seat.

[0015] The central axes of the air inlet channel and the liquid inlet channel are parallel, and the liquid inlet groove is located on one side of the liquid inlet channel.
