[0029] Embodiment 1

[0030] Specifically, as Figs. 1-6As shown in the figure, an atomizer comprises a liquid bottle 3, a flow limiting device 7 and an atomizing system 1, which form a circulation system. Liquid in the liquid bottle 3 enters the atomizing system 1 through the flow limiting device 7, is atomized by the atomizing system 1 and is released into the air. The atomizing system 1 has a liquid inlet and a liquid outlet, and the liquid outlet of the atomizing system 1 is connected to the liquid bottle 3.

[0031] Further, the liquid level in the liquid bottle 3 is higher than that in the atomizing system 1, so that the liquid in the liquid bottle 3 can spontaneously flow into the atomizing system 1 under the action of gravity and pressure. The flow limiting device 7 can control the opening and closing of the liquid passage between the liquid bottle 3 and the atomizing system 1 and / or adjust the size of the liquid flow rate, i.e., the flow limiting device 7 can play a role of interception and / or flow limitation.

[0032] Further, the flow limiting device 7 is provided with a valve, which controls the opening and closing of the liquid passage. The flow limiting device 7 is also provided with a microporous membrane or a cotton stick, and the size of the liquid flow rate can be adjusted by adjusting the specifications of the microporous membrane or the cotton stick, such as the opening area of the microporous membrane, the thickness and density of the cotton stick, etc. Generally, the larger the opening area of the microporous membrane, the larger the liquid flow rate; the smaller the opening area of the microporous membrane, the smaller the liquid flow rate. The larger the thickness of the cotton stick, the smaller the liquid flow rate; the smaller the thickness of the cotton stick, the larger the liquid flow rate, wherein the thickness of the cotton stick is the thickness perpendicular to the liquid flow direction. The microporous membrane or the cotton stick can be arranged at the liquid inlet or the liquid outlet of the flow limiting device 7.

[0033] As some embodiments of the present application, the flow limiting device 7 is a flow regulating valve, such as a ball valve, an angle valve, a butterfly valve, a diaphragm valve, a V-shaped valve, etc.

[0034] Preferably, the microporous membrane is a PTFE membrane.

[0035] Further, the gas pressure in the liquid bottle 3 is equal to that in the atomizing system 1.

[0036] Further, the gas in the atomizing system 1 can enter the liquid bottle 3 through the liquid outlet or be directly discharged into the atmosphere.

[0037] Specifically, as some embodiments of the present application, the liquid bottle 3 is connected to the liquid inlet of the flow limiting device 7 through a liquid inlet pipe 4, the liquid outlet of the flow limiting device 7 is connected to the liquid inlet of the atomizing system 1 through a connecting pipe 5, and the liquid outlet of the atomizing system 1 is connected to the liquid bottle 3 through a backflow pipe 6.

[0038] Further, one end of the reflux pipe 6 is connected with the discharge port of the atomization system 1, and the other end extends into the liquid bottle 3 above the liquid level.

[0039] In use, the liquid in the liquid bottle 3 can spontaneously flow into the flow limiting device 7 under the action of gravity and pressure, flow into the atomization system 1 through the flow limiting device 7, be atomized by the atomization system 1, and then be emitted into the air. When the liquid amount in the atomization system 1 is too much, the flow limiting device 7 can adjust the speed of the liquid in the liquid bottle 3 flowing into the atomization system 1, such as reducing the speed of the liquid in the liquid bottle 3 flowing into the atomization system 1. At the same time, the gas in the atomization system 1 can also flow back to the liquid bottle 3 through the reflux pipe 6, so that the gas pressure in the liquid bottle 3 and the atomization system 1 can be kept consistent, and the atomizer can continuously work.

[0040] As some embodiments of the present application, the liquid bottle 3 is connected with the liquid inlet of the flow limiting device 7 through the liquid inlet pipe 4, the liquid outlet of the flow limiting device 7 is connected with the liquid inlet of the atomization system 1 through the connecting pipe 5, the discharge port of the atomization system 1 is connected with the external air or a liquid return collecting device through the reflux pipe 6, and the liquid bottle 3 is provided with an air hole connected with the external air. The liquid inlet pipe 4, the flow limiting device 7 and the connecting pipe 5 jointly constitute a liquid channel between the liquid bottle 3 and the atomization system 1.

[0041] In use, the liquid in the liquid bottle 3 can spontaneously flow into the flow limiting device 7 under the action of gravity and pressure, flow into the atomization system 1 through the flow limiting device 7, be atomized by the atomization system 1, and then be emitted into the air. Since the discharge port of the atomization system 1 is connected with the external air or a liquid return collecting device through the reflux pipe 6, the pressure in the atomization system 1 is equal to the external atmospheric pressure. Since the liquid bottle 3 is provided with an air hole connected with the external air, the pressure in the liquid bottle 3 = the external atmospheric pressure = the pressure in the atomization system 1, and thus the atomizer can continuously work. When the liquid amount in the atomization system 1 is too much, the flow limiting device 7 can adjust the speed of the liquid in the liquid bottle 3 flowing into the atomization system 1, such as reducing the speed of the liquid in the liquid bottle 3 flowing into the atomization system 1, or even temporarily closing the liquid channel between the liquid bottle 3 and the atomization system 1 to reduce the amount of liquid flowing into the atomization system 1. When the atomization system stops working, the remaining liquid in the atomization system 1 can flow out of the atomization system 1 through the reflux pipe 6 and into the liquid return collecting device.

[0042] As some embodiments of the present application, a blowing device is arranged between the flow limiting device 7 and the atomization system 1, and is connected to the liquid outlet of the flow limiting device 7 and the liquid inlet of the atomization system 1 through the connecting pipe 5, so that the blowing device can blow air into the atomization system 1 to press the liquid in the atomization system 1 into the liquid bottle 3.

[0043] Further, the atomization system 1 comprises an atomization sheet 11 and an atomization pool 12, the atomization sheet 11 can atomize the liquid in the atomization pool 12, the atomization pool 12 is provided with an inlet 13, an outlet 14 and an atomization port, and the cross-sectional area of the inner side of the reflux pipe 6 is less than 1 / 10 of the cross-sectional area of the atomization pool 12.

[0044] Preferably, the cross-sectional area of the inner side of the reflux pipe 6 is less than 1 / 100 of the cross-sectional area of the atomization pool 12.

[0045] Preferably, the outlet of the atomization system 1 is located at the bottom of the atomization pool 12.

[0046] Specifically, when the liquid in the atomization system 1 needs to be discharged due to excessive amount, or the remaining liquid in the atomization system 1 needs to be discharged when the atomization system 1 stops working, the flow limiting device 7 is closed and the blowing device is started to blow air into the atomization system 1. Due to the small inner diameter of the reflux pipe 6, the gas in the atomization system 1 cannot pass through the liquid in the atomization pool 12 and the reflux pipe 6 to enter the liquid bottle in the form of bubbles, but gradually accumulates in the atomization system 1. When the air pressure in the atomization system 1 increases to a certain extent, the gas in the atomization system 1 will press the liquid in the atomization system 1 to enter the reflux pipe 6 and return to the liquid bottle 3 through the reflux pipe 6, realizing the recovery of the liquid in the atomization system 1. With the return, when the liquid level in the atomization system 1 is lower than the outlet of the atomization system 1, the interior of the atomization system 1 and the liquid bottle 3 are connected through the outlet, and the gas pressure in the interior of the atomization system 1 and the liquid bottle 3 can be equalized.

[0047] Further, the air blowing device can draw the gas near the flow limiting device 7 into the atomization system 1, or can draw external gas into the atomization system 1. In order to avoid the gas pressure in the liquid bottle 3 and the atomization pool 12 being too high during long-term use of the atomizer, the liquid bottle 3 and the atomization pool 12 are provided with a gas balance port, which is in communication with external air. By opening the gas balance port, the gas pressure in the liquid bottle 3 and the atomization pool 12 can be equalized with the pressure of the external environment. Preferably, a one-way valve is arranged on the gas balance port. When the gas pressure in the liquid bottle 3 and the atomization pool 12 reaches a specified value, the gas balance port is opened and in communication with the external air. The specified value of the gas pressure is much higher than the pressure for pressing the liquid in the atomization system 1 back into the liquid bottle 3.

[0048] Embodiment 2

[0049] The present application also provides an atomization system. Specifically, as shown in Figs. 2-4 The atomization system 1 comprises an atomization sheet 11 and an atomization pool 12. The atomization sheet 11 can atomize the liquid in the atomization pool 12. The atomization pool 12 is provided with an inlet 13, an outlet 14 and an atomization port. The atomization sheet 11 is arranged on the atomization port, i.e. the atomization sheet 11 is not arranged on the outlet 14. The atomization system 1 has a liquid inlet and a liquid outlet. The inlet 13 is the liquid inlet of the atomization system 1, and the outlet 14 is the liquid outlet of the atomization system 1.

[0050] Preferably, the atomization sheet 11 is a microporous piezoelectric vibration sheet.

[0051] Further, external liquid and / or gas can enter the atomization pool 12 from the inlet 13, and the liquid and / or gas in the atomization pool 12 can be discharged from the atomization pool 12 through the outlet 14.

[0052] Further, the inlet 13 of the atomization pool 12 is connected to a liquid bottle 3. The liquid in the liquid bottle 3 can be delivered into the atomization pool 12 through the inlet 13. The outlet 14 of the atomization pool 12 is connected to the liquid bottle 3. The liquid in the atomization pool 12 can flow back into the liquid bottle 3 through the outlet 14. The gas pressure in the atomization pool 12 can be kept equal to the gas pressure in the liquid bottle 3 through the outlet 14.

[0053] Further, the liquid inlet speed at the inlet 13 is greater than the liquid discharge speed at the outlet 14. The liquid inlet speed is equal to the liquid amount passing through the inlet 13 per unit time, and the liquid discharge speed is equal to the liquid amount passing through the outlet 14 per unit time.

[0054] Further, the liquid level in the atomization pool 12 should be high enough to enable the back of the atomization sheet 11 to contact the liquid in the atomization pool 12 and atomize the liquid in the atomization pool 12 by vibration. In this application, the side surface of the atomization sheet 11 from which the mist is emitted is referred to as the front, and the side surface opposite to the front is referred to as the back of the atomization sheet 11.

[0055] Preferably, the cross-sectional area of the inlet 13 is larger than that of the outlet 14, so that the amount of liquid entering the atomization pool through the inlet 13 is equal to the amount of liquid discharged from the atomization pool through the outlet 14 plus the amount of liquid atomized by the atomization sheet 11.

[0056] Further, the outlet includes a liquid outlet and a gas outlet. When the outlet 14 is in communication with the liquid bottle 3 and is used to balance the air pressure in the atomization system 1 and the liquid bottle 3, the outlet 14 on the atomization pool 12 is the gas outlet of the atomization system 1; when the outlet 14 is in communication with the external atmosphere and is used to make the air pressure in the atomization system 1 equal to the atmospheric pressure, the outlet 14 on the atomization pool 12 is also the gas outlet of the atomization system 1; when the outlet 14 is used to discharge liquid, the outlet 14 is the liquid outlet of the atomization system 1. The gas outlet and the liquid outlet can be different outlets 14 or the same outlet 14.

[0057] In use, the liquid to be atomized enters the atomization pool 12 through the inlet 13, is atomized by the atomization sheet 11, and is emitted into the air; the air and / or liquid in the atomization pool 12 can be discharged through the outlet 14.

[0058] Traditionally, only a liquid inlet is provided on the atomization pool, and the liquid can only flow into the atomization pool in one direction and be discharged by atomization. In this application, the inlet 13 and the outlet 14 are provided on the atomization pool 12, which, on the one hand, enables the liquid in the atomization pool 12, especially the remaining liquid in the atomization pool 12 after each atomization, to be discharged through the outlet 14 and be recycled, thereby achieving recycling of the liquid; on the other hand, enables the air in the atomization pool 12 to flow bidirectionally with the air in the components connected to the outlet 14, such as the liquid bottle 3, the external environment, etc., so that the pressure in the atomization pool 12 and the liquid bottle or the external air, etc. is always equal, and the atomization system 1 can work continuously for a long time.

[0059] The atomization system 1 described in the application is provided with a special inlet 13 on the atomization pool 12 for inputting liquid. Since a cotton swab is not used as a liquid suction channel, the disadvantages of discoloration, odor generation or easy confusion of different flavors can be avoided. In addition, the atomization pool 12 in the atomization system 1 described in the application is separately provided. Since a special inlet 13 is provided on the atomization pool 12, liquid in a liquid bottle can be transmitted to the atomization pool 12 through a pipeline, etc. It is not necessary to invert the liquid bottle 3 above the atomization system 1. Therefore, there is no risk of liquid leakage caused by the inverted liquid bottle.

[0060] As some embodiments of the application, the inlet 13 on the atomization pool 12 is connected with the liquid bottle 3 through a flow limiting device 7. The flow limiting device 7 can deliver the liquid in the liquid bottle 3 to the atomization pool 12 through the inlet 13. The outlet 14 is connected with the liquid bottle 3 through a pipeline. One end of the pipeline is in communication with the outlet 14, and the other end is inserted into the liquid surface in the liquid bottle 3. In the use process, when the flow limiting device 7 is just opened, the gas pre-existing between the flow limiting device 7 and the inlet 13 will enter the atomization pool 12 through the inlet 13 and flow out of the atomization pool 12 through the outlet 14, so that the pressure in the atomization pool 12 can be equal to the pressure in the liquid bottle. Then, the liquid in the liquid bottle 3 is delivered to the atomization pool 12 through the flow limiting device 7 and the inlet 13 for atomization. Since the atomization pool 12 and the liquid bottle 3 are connected through the pipeline provided on the outlet 14, the pressures in the atomization pool 12 and the liquid bottle 3 can always be consistent. The atomization system 1 can work continuously for a long time, and there is no need to set a gas hole on the liquid bottle 3.

[0061] As some embodiments of the application, the atomization pool 12 is provided with a plurality of inlets 13 and a plurality of outlets 14. The inlets 13 are respectively connected with the liquid bottles 3 through flow limiting devices 7. The outlets 14 are respectively connected with the liquid bottles 3.

The position of the third outlet is higher than or equal to the highest liquid level line, preferably, the position of the third outlet is equal to the highest liquid level line, and the third outlet is connected with the external liquid collecting device. The setting of the third outlet can recycle the liquid in the atomization pool 12 when the liquid level in the atomization pool 12 is higher than the highest liquid level line, so as to avoid that the liquid level in the atomization pool 12 is too high. On the other hand, the gas in the atomization pool 12 can flow through the third outlet and be connected with the external liquid collecting device. At this time, the first outlet is the liquid outlet of the atomization system 1, and the third outlet is the liquid outlet and the gas outlet of the atomization system 1.

[0065] As some embodiments of the present application, the atomization pool 12 is provided with one inlet 13 and three outlets 14, the inlet 13 is connected with the liquid bottle 3 through the flow limiting device 7, the outlets 14 are respectively connected above the liquid level of the liquid bottle 3, the liquid bottle 3 is located above the atomization pool 12, and the atomization sheet 11 is vertically arranged on the side of the atomization pool 12. The liquid in the liquid bottle 3 spontaneously flows into the atomization pool 12 by the action of gravity or pressure.

The third outlet is arranged, on the one hand, when the liquid level in the atomization pool 12 is higher than the highest liquid level line, the liquid in the atomization pool 12 can be backflowed into the liquid bottle 3 in a pumping manner through the third outlet, so as to avoid that the liquid level in the atomization pool 12 is too high; on the other hand, when the liquid in the atomization pool 12 is lower than the position of the third outlet, the gas in the atomization pool 12 can be connected with the gas in the liquid bottle 3 through the third outlet, so that the gas pressure in the atomization pool 12 and the liquid bottle 3 is equal, and then the atomization system 1 can continuously and stably work.

[0066] At this time, the first outlet is the liquid outlet of the atomization system 1, the second outlet is the gas outlet of the atomization system 1, and the third outlet is the gas outlet and the liquid outlet of the atomization system 1.

[0067] As some embodiments of this application, the atomizing pool 12 is provided with one inlet 13 and two outlets 14.
