Description

TECHNICAL FIELD The present disclosure relates to a technical field of atomization, in particular to an atomizing device. BACKGROUND Aerosol is a colloidal dispersion system formed by small solid or liquid particles dispersed and suspended in a gas medium. Since the aerosol can be absorbed by a human body through a respiratory system, it provides users with a new alternative absorption method. An atomizing device is configured to atomize an atomizing medium by heating or ultrasound to generate the aerosol. The atomizing medium include nicotine-containing e-liquid, medical drugs, skin care lotions, etc. The atomizing medium is atomized to generate the aerosol that can be inhaled as an alternative to conventional inhaled product. The existing atomizing devices can be divided into closed-type atomizing devices and open-type atomizing devices according to the way of liquid injecting. The atomizing medium of the closed-type atomizing device is filled during the production and cannot be refilled after use, so the cost is higher for the user. The open-type atomizing device is provided with a liquid injecting hole on a shell thereof and sealed with a sealing element. After the atomizing medium in the atomizing device is used up, the sealing element can be provided to refill atomizing device with the atomizing medium, so the open-type atomizing device can be reused, thereby reducing the cost and more environmentally friendly. However, the sealing element of the open-type atomizing device is easy to open. If a child opens the sealing element, it is easy to cause leakage and there is a risk of eating the atomizing medium by the child. WO 2021/140317 A1 discloses a atomizing device with a body and a changeable cartridge having a chamber, wherein the chamber is refillable via openings. EP 3 498 113 A1 discloses an electronic smoking device with an atomizer/liquid reservoir portion. In order to facilitate refilling a liquid reservoir, the atomizer/liquid reservoir portion comprises a docking valve for docking a source of liquid to be stored in the liquid reservoir, wherein the docking valve is adapted to form a snap-fit connection with a counter docking valve of a source of liquid. SUMMARY Accordingly, an atomizing device according to claim 1 is provided, which can prevent children from opening a liquid injecting hole and causing leakage and accidental ingestion liquid. An atomizing device includes a liquid storing element provided with a liquid injecting hole, a sealing element detachably connected to the liquid storing element and configured to seal the liquid injecting hole, and a protecting element connected to the liquid storing element. The protecting element is movable relative to the liquid storing element and is capable of switching between a first position and a second position, wherein the shielding area of the sealing element by the protecting element in the first position is greater than the shielding area of the sealing element by the protecting element in the second position.

When the protecting element is in the first position, the protecting element is capable of rotating around the axial direction of the liquid storing element and is capable of switching between a locking state and an unlocking state; when the protecting element is in the locking state, the protecting element is fixed relative to the liquid storing element in the axial direction of the liquid storing element; when the protecting element is in the unlocking state, the protecting element is capable of moving in the axial direction of the liquid storing element to be switched to the second position. In one of the embodiments, one of the liquid storing element and the protecting element is provided with a buckle, the other one of the liquid storing element and the protecting element is provided with a first guiding groove extending along the circumferential direction of the liquid storing element, when the protecting element is in the locking state, the buckle is engaged in the first guiding groove. In one of the embodiments, a transiting portion protrudes within the first guiding groove, when the protecting element is in the unlocking state, the buckle abuts against the transiting portion to be disengaged from the first guiding groove. In one of the embodiments, one of the liquid storing element and the protecting element provided with the first guiding groove is further provided with a second guiding groove, the second guiding groove is located on a side of the first guiding groove in the axial direction of the liquid storing ele
