Description

Fragrance expanding machine Technical Field The utility model relates to the field of aromatherapy machines, in particular to an aroma expanding machine. Background The aromatherapy machine is used as a common household appliance in modern life, and converts aromatherapy liquid into fine mist through a specific technical means so as to achieve multiple effects of aromatherapy, humidification, air purification and the like. Among the many types of aromatherapy machines, the design of utilizing high pressure gas to generate negative pressure to extract and mix the aromatherapy liquid for atomization is favored for its efficient and rapid aromatherapy emission characteristics. The operating principle of the aromatherapy machine is that high-pressure gas forms negative pressure through a specific device to attract aromatherapy liquid to enter a mixing area, then the high-pressure gas and the aromatherapy liquid are refined into tiny particles in the high-speed mixing process, and finally the tiny particles are emitted in an atomization mode, so that a pleasant aromatherapy atmosphere is created. In the existing aromatherapy machine products adopting the high-pressure gas atomization technology, one of the structures is to compress external air into high-pressure gas through an air pump and convey the high-pressure gas to a pressure inner cavity inside the aromatherapy machine. The pressure cavity is used for supplying air to the atomizing assembly, and the structure is that an air inlet positioned in the pressure cavity is directly arranged on the atomizing assembly. The atomizing assembly has the advantages that when the atomizing assembly is installed, the installation direction and the angle are not needed to be considered, the atomizing assembly is only required to be inserted and screwed or clamped, the air inlet naturally falls into the pressure cavity, and the pressure cavity is sealed through the sealing assembly, so that a sealed pressure cavity is formed. The structure is simpler to operate and does not need to consider the condition of air leakage. The pressure cavity plays an important role, and receives high-pressure gas from the air pump and guides the gas to the atomizing head, so as to provide a stable gas source with certain pressure for the atomizing head, thereby ensuring that the aromatherapy liquid can be atomized smoothly and uniform fog can be formed. However, the pressure lumen design of the prior art exposes a series of challenges in practical production and application. On the one hand, the pressure in the cavity is not easy to control. The change of the shape and the size of the pressure inner cavity can change the flow path and the spatial distribution of the gas in the cavity, so that the high-pressure gas output by the air pump is difficult to establish a stable pressure environment in an expected mode after entering the cavity. When the shape of the pressure cavity is complex or the size of the pressure cavity is deviated, irregular flow phenomena such as vortex and backflow can be generated in the cavity, and the pressure actually applied to the atomizing head is greatly deviated from the output pressure set by the air pump. The instability of the pressure can lead to good atomization effect of the aromatherapy liquid, the generation amount and uniformity of the mist can not be effectively ensured, and the integral use performance and user experience of the aromatherapy machine are further affected. On the other hand, the pressure distribution in the cavity is not uniform. Under the condition that the size and the specification of the pressure cavity are not uniform, the pressure difference of the gas at different positions of the cavity is obvious. The air pressure may be relatively high in certain areas near the air pump inlet or pressure chamber, while the air pressure may be relatively low in areas away from these areas. The non-uniformity of the pressure distribution can lead to inconsistent air pressure effect on each part of the atomizing head, so that the atomization degree of the aromatherapy liquid on the atomizing head is different. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provides a solution of the aromatherapy machine, which can effectively solve the problems that the pressure in the pressure cavity is not easy to control and the distribution is uneven. The utility model adopts the technical scheme that the fragrance-diffusing machine comprises a main body, an atomizing head and a container, wherein the atomizing head is connected with the container and is used for pumping liquid in the container and mixing the liquid with high-pressure gas to form mist to escape out of the cover body, a sealing component is arranged between the atomizing head and the main body to realize sealing connection, a pressure inner cavity is formed in the main body, a high-pressure air source is arranged to provide high-pressure air for
