The gas-liquid mixture that flows out of the end of the diversion structure 14 collides with the collision surface of the collision body 15 at a high speed to form atomized particles which splash to the periphery, the atomized particles are screened through the cavity wall of the atomization cavity 121, large particles are deposited and mixed in the liquid storage cavity 131, and small particles are sprayed out from the mist outlet 111 under the action of outside air.

If the collision face at collision body 15 and stock solution chamber 131 treat between the liquid level of atomizing liquid and not set up shielding plate 16, along with atomizing going on, the liquid of treating in the stock solution chamber 131 is consumed, the liquid level descends in the stock solution chamber 131, make collision body 15's collision face and stock solution chamber 131 treat the distance between the liquid level of atomizing liquid grow gradually, the unable deposit of large granule in the atomizing granule that atomizes in atomizing chamber 121 is most mixed by atomizing in stock solution chamber 131 once more, and then make the proportion of the little granule of outlet 111 department decline, the not good phenomenon of atomization effect appears. This application sets up the shielding plate 16 through the collision face at collision body 15 and stock solution chamber 131 treat between the liquid level of atomizing liquid for along with atomizing going on, the distance between collision body 15's collision face and the shielding plate 16 is unchangeable, and not change along with treating the reduction of atomizing liquid in the stock solution chamber 131, the large granule majority in the atomizing granule that atomizing chamber 121 atomizes is attached to shielding plate 16 and can't reach out fog mouth 111, thereby stabilize out the proportion of the tiny granule of fog mouth 111 department, and then realize better atomization effect.

Referring to fig. 25 and 26, fig. 25 is a schematic structural view of a portion of the atomizing cup assembly provided in fig. 4, and fig. 26 is a schematic structural view in a top view provided in fig. 25.

The baffle plate 16 is circumferentially arranged around the flow guide structure 14 and fixed on the side wall of the flow guide structure 14; that is, the shielding plate 16 has an integral structure, and the shielding plate 16 has an annular structure, and may be a square ring, a circular ring, a polygonal ring, or the like. Preferably, the shielding plate 16 is a circular ring, so that the shielding plate 16 is convenient to process and assemble, and the shielding plate 16 provides a more uniform attachment surface for the atomized large particles, which is beneficial to stabilizing the proportion of the fine particles at the mist outlet 111. In another embodiment, the atomizing cup assembly 1 includes a plurality of shielding plates 16, the plurality of shielding plates 16 are arranged around the circumferential direction of the flow guiding structure 14 at intervals, and the distance between the plurality of shielding plates 16 is designed as required, so that the proportion of the fine particles at the mist outlet 111 can be stabilized.

In one embodiment, the distance between the collision surface of the collider 15 and the shielding plate 16 is 13-16mm; preferably, it is 15mm. This is because the distance between the collision surface of the collider 15 and the surface of the shielding plate 16 close to the collider 15 is too small, so that the amount of mist is small, and the use experience of the user is reduced; the distance between the collision surface of the collision body 15 and the surface of the shielding plate 16 close to the collision body 15 is too large, which is not favorable for the deposition of large particles in the atomized particles, and thus, the better atomization effect cannot be realized.

In one embodiment, the distance between the end surface of the cavity wall of the atomizing cavity 121 and the shielding plate 16 is 3-6mm; preferably, it is 5mm. This is because the distance between the end surface of the cavity wall of the atomizing cavity 121 and the surface of the shielding plate 16 close to the collision body 15 is too small, so that the amount of mist is small, and the use experience of the user is reduced; the distance between the end surface of the wall of the atomization cavity 121 and the surface of the shielding plate 16 close to the collision body 15 is too large, which is not favorable for the deposition of large particles in the atomized particles, and thus the better atomization effect can not be realized.

Referring to fig. 4 and 26, the shielding plate 16 is spaced from the sidewall of the cup 13, and a first notch 161 is formed at a side of the shielding plate 16 contacting the baffle structure 14. It can be understood that the shielding plate 16 is spaced from the side wall of the cup body 13, so that the large particles in the atomized particles can be atomized again after being deposited on the shielding plate 16 and then flowing into the liquid storage chamber 131 through the gap between the shielding plate 16 and the side wall of the cup body 13; a first notch 161 is formed on the side of the shielding plate 16 contacting the diversion structure 14 to balance the air pressure in the liquid storage chamber 131 and the side of the shielding plate 16 away from the liquid storage chamber 131, so that the liquid deposited on the shielding plate 16 can flow into the liquid storage chamber 131 from the gap between the shielding plate 16 and the side wall of the cup body 13.

Referring to fig. 25, the atomizing cup assembly 1 further includes a connecting member 19, and the collision body 15 is fixed to the flow guide structure 14 through the connecting member 19; the connecting member 19 includes a first sub-connecting member 191 and a second sub-connecting member 192, the extending direction of the first sub-connecting member 191 is perpendicular to the extending direction of the second sub-connecting member 192, and the extending direction of the first sub-connecting member 191 is the same as the extending direction of the flow guide structure 14. Optionally, the end of the first sub-connector 191 remote from the second sub-connector 192 abuts the shutter 16, so that the connector 19 is fixed to the side wall of the baffle structure 14 together with the shutter 16.

Referring to fig. 27 and 28, fig. 27 is a schematic top view diagram of another embodiment of the partial structure provided in fig. 25, and fig. 28 is a schematic top view diagram of another embodiment of the partial structure provided in fig. 25.

Further, a second notch 162 is provided at a side of the shielding plate 16 away from the flow guiding structure 14. The shape and size of the second notch 162 can be designed as required, so that the liquid deposited on the shielding plate 16 can flow into the liquid storage chamber 131 from the second notch 162.

In one embodiment, the shielding plate 16 is a ring, and the second notch 162 is fan-shaped. Specifically, the second notch 162 includes two oppositely disposed side edges and a bottom edge connecting the two side edges (as shown in fig. 27); the angle between the two side extension lines is 50-70 degrees, preferably 60 degrees. The included angle between the two sides of the second notch 162 is too small to allow the liquid deposited on the shielding plate 16 to flow into the liquid storage chamber 131 from the second notch 162; the included angle between the two sides of the second notch 162 is too large, so that the large particles in the atomized particles cannot deposit on the shielding plate 16, that is, the distance between the collision surface of the collision body 15 and the liquid surface of the liquid to be atomized in the liquid storage cavity 131 cannot be ensured to be stable without descending along with the liquid surface in the liquid storage cavity 131.

In another embodiment, the shielding plate 16 is a circular ring, and the second notch 162 is fan-shaped; specifically, the second notch 162 includes two opposite side edges (as shown in fig. 28), so that the liquid deposited on the shielding plate 16 can flow into the liquid storage chamber 131 from the second notch 162.

Through experiments, it is found that some of the atomized particles atomized in the atomization region 151 adhere to the connection member 19, and in order to facilitate the droplets adhering to the connection member 19 to flow into the liquid storage chamber 131 to be atomized again, a side of the second notch 162 is flush with the surface of the second sub-connection member 192.

Referring to fig. 27, since the two second sub-connecting pieces 192 are symmetrically arranged on both sides of the collision body 15, and atomized particles are adhered to the two second sub-connecting pieces 192, optionally, two second notches 162 are symmetrically arranged on the shielding plate 16, and one side of each of the two second notches 162 is flush with the surface of the corresponding second sub-connecting piece 192, which is beneficial for liquid deposited on the connecting piece 19 to enter the liquid storage cavity 131. It will be appreciated that the two second notches 162 are symmetrically disposed on the shielding plate 16, which is also beneficial for the liquid deposited on the shielding plate 16 to flow into the liquid storage chamber 131 and keep the shielding plate 16 balanced.

The screening plate 144 is disposed around the flow guiding structure 14 and fixed to the sidewall of the flow guiding structure 14; that is, the screening plate 144 has an annular configuration. One end of the screening plate 144 abuts against the end of the fourth hollow projection 1224 on the cover body 12, and the screening plate 144 and the fourth hollow projection 1224 together enclose a space formed as the atomizing chamber 121. Atomized particles formed after gas-liquid mixture flowing out of the end of the flow guide structure 14 impacts the impact surface of the collision body 15 at high speed splash to the periphery, the atomized particles are screened through the cavity wall of the atomization cavity 121, large particles are deposited and mixed in liquid in the liquid storage cavity 131, and small particles are sprayed out from the mist outlet 111 under the action of outside air.
