Description

Fragrance expanding machine Technical Field The utility model relates to the technical field of fragrance expanding machines, in particular to a fragrance expanding machine. Background A fragrance dispenser, also known as a fragrance dispenser or air freshener, is a device capable of converting liquid essential oils into gaseous molecules that diffuse into the air. For make full use of space places the air pump, the atomizing subassembly is placed on current machine that expands adopts upper portion, the valve setting of air pump is placed to the lower part, major structure is including the stack shell that is equipped with inner tube and urceolus, connect the atomizing subassembly at stack shell top, be equipped with the atomizing core in the atomizing subassembly, holding essential oil bottle in the inner tube, the air pump is placed to the urceolus space of inner tube bottom, the export of air pump is through air duct intercommunication inner tube inner chamber, be equipped with the liquid passageway of connecting the essential oil bottle and the gas passage of intercommunication inner tube inner chamber on the atomizing core respectively, utilize the air current that the air pump produced, from atomizing core gas outlet blowout, form the liquid outlet of the essential oil suction atomizing core of negative pressure in with the essential oil bottle, after with the gas mixing atomizing, follow atomizing subassembly's play fog mouth discharge. Because the inner cavity of the inner cylinder is used for air intake, the sealing effect between the cylinder body and the atomization assembly determines the amount of air entering the atomization core, and in order to replace the essential oil bottle, the cylinder body and the atomization assembly are connected in a threaded or clamping mode, and the sealing effect can be influenced by the operation during disassembly and installation. For this reason, chinese patent publication No. CN220142248U discloses a novel fragrance-emitting machine structure, which comprises a base and an outer body, wherein the outer body comprises an upper cavity and a lower cavity, an atomizing core frame is connected above the upper cavity, an inner cylinder sealing ring is annularly fixed on the atomizing core frame, the effect of which is to improve the sealing performance between the atomizing core frame and the inner cylinder, and prevent the gas in the inner cylinder cavity from diffusing out from the gap between the atomizing core frame and the inner cylinder to affect the gas supply of the atomizing core, wherein the inner side of the top of the inner cylinder is also provided with an angle boss, when the atomizing core frame is fixed on the inner cylinder, the angle boss extrudes the inner cylinder sealing ring to ensure the sealing performance between the atomizing core frame and the inner cylinder. However, in this kind of scheme of putting, the inner tube sealing washer is installed on the lateral wall of atomizing core frame to just can reach sealed effect through the slant extrusion between angle boss and the inner tube sealing washer, and because be threaded connection between atomizing core frame and the inner tube, so when adopting rotatory mode to connect or dismantle between atomizing core frame and the inner tube, angle boss is because with the slant extrusion between the inner tube sealing washer, so angle boss can not be followed and drive the inner tube sealing washer to twist reverse and produce deformation, even probably lead to the inner tube sealing washer to drop from atomizing core frame's lateral wall, and then influence the sealed effect between atomizing core frame and the inner tube. In order to solve the problem of gas leakage, the prior art still adopts the mode of multichannel sealing washer to seal barrel and atomizing subassembly, and such scheme also has the installation complicacy, can also because the sealing washer upset displacement causes the not tight problem of seal in the use. The application aims to solve the technical problem of designing the fragrance expanding machine which can not cause torsion deformation to the sealing element when the atomizing device is installed or detached and can effectively ensure the sealing effect between the atomizing device and the inner cylinder. Disclosure of utility model In order to overcome the defects in the prior art, the utility model aims to provide the fragrance expanding machine which can not cause torsion deformation to a sealing element when an atomization device is installed or detached and can effectively ensure the sealing effect between the atomization device and an inner cylinder. The utility model adopts the technical scheme that the fragrance-diffusing machine comprises an atomization assembly and a barrel body which are connected with each other, wherein the barrel body comprises an outer barrel and an inner barrel arranged in the outer barrel, an airflow channel for airflow to pass thr
