The cross-sectional dimensions of the air guide tube 141 in the first area are the same, and the second area The cross-sectional dimension of the air duct 141 in the middle decreases gradually in the direction away from the bottom wall of the liquid storage cavity 131; The velocity of the gas coming out of the medium increases. After the air pump (not shown) in the atomizing host 2 pumps gas from the small-diameter passage at the end of the air guide tube 141, due to the Venturi effect, a negative pressure is formed at the end of the small-diameter passage, and the negative pressure pushes the cup body 13 The liquid at the bottom of the liquid storage chamber 131 is sucked up from the liquid guide channel 143 formed by the cooperation of the water guide sleeve 142 and the air guide tube 141.

If the baffle plate 16 is not set between the collision surface of the collision body 15 and the liquid level of the liquid to be atomized in the liquid storage chamber 131, as the atomization proceeds, the liquid to be atomized in the liquid storage chamber 131 will be consumed. The liquid level in the liquid storage chamber 131 drops, so that the distance between the collision surface of the collision body 15 and the liquid level of the liquid to be atomized in the liquid storage chamber 131 gradually increases, and the atomized particles in the atomization chamber 121 Most of the large particles cannot be deposited and mixed in the liquid storage chamber 131 to be atomized again, which reduces the proportion of tiny particles at the mist outlet 111 , resulting in a poor atomization effect. In this application, the baffle plate 16 is set between the collision surface of the collision body 15 and the liquid surface of the liquid to be atomized in the liquid storage chamber 131, so that as the atomization proceeds, the gap between the collision surface of the collision body 15 and the baffle plate 16 The distance remains constant, and does not change with the decrease of the liquid to be atomized in the liquid storage chamber 131. Most of the large particles in the atomized particles atomized by the atomization chamber 121 are attached to the baffle plate 16 and cannot reach the mist outlet. 111, so as to stabilize the proportion of tiny particles at the mist outlet 111, thereby achieving a better atomization effect.

Wait. Preferably, the shielding plate 16 is a ring, which makes the shielding plate 16 easy to process and assemble, and the shielding plate 16 provides a more uniform distribution of the attachment surface for the atomized large particles, which is conducive to stabilizing the proportion of tiny particles at the mist outlet 111. In another embodiment, the atomizing cup assembly 1 includes a plurality of baffle plates 16, which are arranged at intervals around the circumference of the flow guide structure 14, and the distance between the plurality of baffle plates 16 is designed according to needs, and can It is sufficient to achieve a stable proportion of tiny particles at the mist outlet 111.

In one embodiment, the distance between the collision surface of the collision body 15 and the shielding plate 16 is 13-16 mm; preferably, it is 15 mm. This is because 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 small, so that the amount of mist is small and reduces the user's sense of experience; the collision surface of the collision body 15 and the shielding The distance between the surfaces of the plate 16 close to the collision body 15 is too large, which is not conducive to the deposition of large particles in the atomized particles, and thus cannot achieve a better atomization effect.
