Description

Technical Field

[0001] The present invention relates to the technical field of fluid transportation, and in particular to a liquid discharge device and an atomizer. Background Art

[0002] In daily life, especially in daily chemical products, it is often necessary to discharge liquid through a liquid discharge device. At present, there are two main ways of discharging liquid from the liquid discharge device: one is that the liquid storage bottle is set below the liquid discharge device, and the liquid is discharged by pressing the liquid discharge device to change the pressure difference on both sides of the liquid; the other is that the liquid storage bottle is inverted above the liquid discharge device. When liquid discharge is required, the liquid discharge device is opened, and the liquid is discharged under the action of gravity, etc. When liquid discharge is not required, the liquid discharge device is closed, and the liquid cannot continue to be discharged.

[0003] When the liquid storage bottle is inverted above the liquid outlet device, leakage is likely to occur. For example, an aromatherapy machine equipped with a microporous atomizer generally comprises, from bottom to top, a base, a power unit, an atomizer, and a water tank. The atomizer includes at least a microporous atomizer. The atomizer is connected to the liquid outlet at the bottom of the water tank through the liquid outlet device. After the water and essential oil are discharged through the liquid outlet device, they form a mist through the microporous atomizer and are ejected from the spray nozzle. Because the water tank is located above the liquid outlet device and the atomizer, when the aromatherapy machine is in use, the microporous atomizer may leak liquid due to the pressure difference between the two sides. Existing methods use a manual fluid control valve, such as a switch, that is opened when in use and closed when not in use. This method requires manual operation, which is cumbersome and often causes users to forget to close the fluid control valve, causing the microporous atomizer to leak liquid. Furthermore, it reduces the automation and intelligence level of the aromatherapy machine.

[0004] Therefore, providing a liquid outlet device and an atomizer that can effectively prevent liquid leakage from a microporous atomizing sheet and can be intelligently controlled is one of the technical problems that need to be urgently solved by those skilled in the art. Summary of the Invention

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0032] Example 1

[0033] Specifically, such as Figures 1 to 6 As shown, a liquid discharge device, the liquid discharge device 3 includes an air pipe 31, a connecting piece and a fluid control device 34, the liquid storage bottle 1 is inverted above the liquid discharge device 3, and the connecting piece is provided with a gas phase channel connected to the outside, one end of the air pipe 31 is connected to the liquid surface above the liquid storage bottle 1, and the other end is connected to the gas phase channel on the connecting piece, and the connecting piece is also provided with a liquid phase channel, one end of the liquid phase channel is connected to the liquid storage bottle 1, and the other end of the liquid phase channel is connected to the outside through the fluid control device 34.

[0034] When in use, the fluid control device 34 is opened, and under the action of gravity, the liquid in the liquid storage bottle 1 can be discharged through the liquid phase channel on the connecting piece. As the liquid is discharged, the pressure in the liquid storage bottle 1 becomes smaller. In order to balance the pressure difference inside and outside the liquid storage bottle 1, external gas enters the liquid storage bottle 1 through the gas phase channel on the connecting piece and the air pipe 31 to maintain the pressure balance inside and outside the liquid storage bottle 1.

[0035] The liquid outlet device 3 described in the present application has a simple structure, and the pressure inside and outside the liquid storage bottle 1 can quickly reach equilibrium. In particular, after the fluid control device 34 is closed, the pressure at various locations inside the liquid outlet device 3 can quickly reach equilibrium with the external pressure, and the liquid outlet device 3 will not continue to discharge or leak liquid. When used in a nebulizer, the pressure on both sides of the microporous atomizing plate of the nebulizer can be made basically equivalent, thereby avoiding leakage at the microporous atomizing plate of the nebulizer.

[0036] Furthermore, the connecting member includes a first connecting member 32 and a second connecting member 33. The first connecting member 32 is a cylindrical structure with a hollow interior. The end of the first connecting member 32 close to the liquid storage bottle 1 is open, and the end of the first connecting member 32 away from the liquid storage bottle 1 has a bottom surface. The first connecting member 32 covers the bottle mouth 11 of the liquid storage bottle 1. A first liquid hole is provided on the bottom surface of the first connecting member 32. The first connecting member 32 is also provided with a first gas phase channel connected to one end of the air pipe 31.

[0037] Furthermore, the second connecting member 33 is a cylindrical structure with a hollow interior. The end of the second connecting member 33 close to the liquid storage bottle 1 is open, and the end of the second connecting member 33 away from the liquid storage bottle 1 has a bottom surface. The first connecting member 32 is accommodated in the second connecting member 33. A second liquid hole is provided on the bottom surface of the second connecting member 33. The second liquid hole is arranged corresponding to the first liquid hole and is connected to each other. The second connecting member 33 is also provided with a second gas phase channel connected to the first gas phase channel on the first connecting member 32.

[0038] Preferably, the first liquid hole is located at the center of the bottom surface of the first connecting member 32 ; the second liquid hole is located at the center of the bottom surface of the second connecting member 33 .

[0039] Furthermore, the first gas phase channel includes a first air hole located on the bottom surface of the first connecting member 32 and a gas phase connecting portion connected thereto. The gas phase connecting portion is a circular tubular structure axially arranged on the first connecting member 32, and one end of the air pipe 31 is accommodated in the gas phase connecting portion.

[0040] Furthermore, the second gas phase channel includes a second air hole located on the second connecting member 33, and the second air hole is connected to the first air hole.

When in use, the liquid is discharged to the atomizing port through the first liquid hole, the second liquid hole and the fluid control device 34, and then atomized by the microporous atomizing sheet in the atomizing port and released into the air. Under the action of the pressure difference, the external gas enters the atomizing device 35 from the microporous atomizing sheet on the atomizing port, and then enters the liquid storage bottle 1 through the third gas phase channel, the second gas phase channel, the first gas phase channel and the air pipe 31 in sequence.

[0045] In addition, when the atomizing device 35 is just started, the substances discharged together with the second end of the fluid control device 34 include liquid and a small amount of residual gas. The setting of the atomizing port and the third gas phase channel on the atomizing device 35 can enable this small amount of residual gas to enter the liquid storage bottle 1 through the third gas phase channel, the second gas phase channel, the first gas phase channel and the air pipe 31, so that the liquid discharge is smoother and the gas balance is faster.

Through the first sealing ring 36 and the second sealing ring 37, an annular gas circulation channel is formed between the bottom surface of the first connecting member 32 and the bottom surface of the second connecting member 33. On the one hand, the air intake of the liquid outlet device 3 is faster; on the other hand, the first air hole and the second air hole do not need to be provided accordingly, and the position setting of the first air hole and the second air hole is more flexible, and can be connected through the first sealing ring 36 and the second sealing ring 37.

[0047] As some embodiments of the present application, the air pipe 31 can be a tubular structure independently provided in the liquid storage bottle 1 , or can be a gas phase channel provided on the side wall of the liquid storage bottle 1 through integral molding.
