Referring to fig. 1 to 6, in one embodiment of the present utility model, an air intake structure of a spray head includes a spray head 1, a gas passage 2 provided in the spray head 1; one end of the gas channel 2 is connected with a peripheral gas source, and the other end of the gas channel 2 is connected with a peripheral atomization core 8;

the gas channel 2 is provided with a liquid storage cavity 3.

In practical application scenario, the gas channel 2 can often feed liquid, and liquid can flow into the air pump, and the air pump is easy to damage after a period of use. In order to solve this problem, by providing a liquid storage chamber 3 in the gas passage 2, a small amount of liquid can be stored, and when the air pump is restarted, the liquid is blown out, and the liquid does not flow back into the pump.

The "on the gas channel 2" in this embodiment means that the liquid storage cavity 3 may be a part of the gas channel 2, or small recesses may be dug in the lower surface of the gas channel 2.

More preferably, a portion of the gas channel 2 comprises at least one U-shaped section; the bottom of the U-shaped section is the liquid storage cavity 3.

The U-shaped section has the advantage that the flow direction of the gas can be changed, so that the gas directly impacts the liquid storage cavity 3, the liquid in the liquid storage cavity 3 is brought out, and meanwhile, the volume of the liquid storage cavity 3 with the design is also large enough.

Preferably, the height of the liquid storage cavity 3 is lower than the height of the end of the gas channel 2 connected with the gas source. However, the height of the liquid storage cavity 3 is not exclusive to be higher than the height of the end, connected with the air source, of the air channel 2, and in this case, the air channel 2 is bent once more, so that the air flow resistance is improved.

In practical application, be equipped with atomizing seat 4 on the atomising head 1, atomizing seat 4 is used for connecting the atomizing core 8 of peripheral hardware, the tip of gas channel 2 extends to on the atomizing seat 4, be equipped with cavity 5 in the atomising head 1, the bottom of cavity 5 is the sealed end, cavity 5 separates into a U type passageway 6 through a baffle 17, the air supply is connected to the one end of U type passageway 6, atomizing seat is connected to the other end of U type passageway 6 and switches on with the atomizing core 8 of peripheral hardware.

The U-shaped channel 6 is herein the above U-shaped section.

More specifically, the bottom of the cavity 5 is plugged and sealed by a sealing plug 7 (omitted in fig. 3-5 and shown in fig. 6), so that the bottom of the cavity 5 is not directly sealed by injection molding because of injection molding difficulty, and the injection molding difficulty can be reduced by additionally adding a sealing plug 7.

Example 2

Referring to fig. 1-10, a spray head comprises a spray head 1 and a spray core 8, wherein an atomization seat 4 is fixed on the spray head 1, the spray core 8 is fixed on the atomization seat 4, and an air outlet 9 and a liquid outlet 10 are arranged on the spray core 8; the atomizing head 1 is provided with a liquid channel 16 and a gas channel 2 which extend to the atomizing seat 4, and the gas channel 2 is an air inlet structure as described in the embodiment 1; one end of the gas channel 2 is communicated with the gas outlet 9, and the other end of the gas channel is communicated with an external gas source; one end of the liquid channel is communicated with the liquid outlet 10, and the other end of the liquid channel is communicated with an external liquid supply container.

The spray head of this embodiment is substantially the same as cn202020268404.X except for the air intake structure. The working process is as follows: the air source, namely the air pump blows pressurized air, the pressurized air is blown out from the air outlet 9 and is blown to the vicinity of the liquid outlet 10, so that the vicinity of the liquid outlet 10 is negative pressure to drive the liquid in the liquid supply container to be output through the liquid outlet 10, and the liquid and the compressed gas are mixed to form spray. If the machine is stopped, the fog can be settled, a small amount of fog can enter the air outlet 9, and is stored through the liquid storage cavity 3, and when the machine is started next time, the air in the liquid storage cavity 3 is blown out by the air of the air pump, so that the accumulated liquid cannot flow back to the air pump.

More specifically, the air outlet 9 of the atomizing core 8 extends upwards, and an included angle formed by an extension line of the air outlet 9 and the axis of the liquid outlet 10 is 45 ° -135 °; the atomizing core 8 is provided with a shielding block 11 with a wedge-shaped tip, and the shielding block 11 is positioned above the air outlet 9 and shields part of the air outlet 9; the outlet 10 is located at the wedge-shaped tip.

One of the main reasons for the mist flowing back to the gas channel 2 in practice is that the wedge blocks are sloping surfaces up and down, and the liquid can slide down the sloping surfaces into the gas channel 2. Optimization of the intake structure of the present embodiment is necessary.

Example 3

Referring to fig. 1-12, an aroma diffusing device forms an atomization by adopting the atomizing head, wherein the atomizing head further comprises an atomizing cover 12, the atomizing cover 12 and the atomizing head 1 form an atomizing cavity, and the atomizing base 4 is positioned in the atomizing cavity; the atomizing cover 12 is provided with an atomizing pipe 13, an air inlet pipe 14 is arranged below the atomizing pipe 13, a baffle ring 15 is arranged below the atomizing cover 12, one end of the atomizing pipe 13 extends to the inner side of the baffle ring 15, and one end of the air inlet pipe 14 extends to the outer side of the baffle ring 15 and is positioned on one side, close to the free end of the atomizing pipe 13, of the atomizing cover 12.
