In the actual use process, two application conditions are divided, one is that the commodity is in the storage and transportation process, and at this time, the liquid containing cavity 1 and the spraying head 2 are possibly connected together, so that the use is convenient for a client after receiving the commodity. In this case, the film cannot be broken, and the liquid flow path 21 is blocked. In another application, the spray head 2 and the liquid containing chamber 1 are separated before installation and use, and this embodiment can prevent the liquid in the liquid containing chamber 1 from leaking during installation.

The film breaking mode is divided into automatic mode and manual mode, and the manual mode is simple, namely after a customer receives a commodity, the atomizing base 23 is taken down from the atomizing head 22, the film is broken through any optional tool, and then the atomizing base 23 and the atomizing head 22 are assembled again.

This embodiment emphasizes the automatic case.

Preferably, the atomizing base 23 is hermetically inserted on the atomizing head 22; further comprises a first puncturing assembly 32 for puncturing the first film 31;

in the design, the first film 31 is disposed on the atomizing base 23 and the first piercing assembly 32 is disposed on the atomizing head 22;

This has the advantage that firstly, the air intake quantity is increased and secondly, even a slight relative offset of the atomizing seat 23 and the atomizing head 22 is permitted.

More specifically, in order to improve the convenience of use for the user, the atomizing head 2 further includes an atomizing cap 4 provided on the atomizing head 22; the atomizing cover 4 and the atomizing head 22 are connected in a relatively movable manner in the vertical direction;

the bottom of the atomizing cover 4 is fixedly connected with a pressing component 41; the pressing assemblies 41 are two vertically arranged plate bodies in the embodiment, the plate bodies extend to the upper surface of the atomizing base, and the pressing assemblies 41 are used for pressing the atomizing base 23 downwards to enable the insertion depth of the atomizing base 23 and the atomizing head 22 to change from a first depth to a second depth;

the first depth is the inserting depth of the atomizing base 23 and the atomizing head 22 when the first piercing assembly 32 does not pierce the first film 31;

the second depth is the insertion depth of the atomizing base 23 and the atomizing head 22 when the first piercing assembly 32 pierces the first film 31.

In this embodiment, the first depth should be significantly greater than the second depth, and the difference between the first depth and the second depth should be equal to the distance between the previous card slot and the next card slot.

As a recovery means of essential oil or fragrant liquid commonly used in the field, the recovery device further comprises a backflow hole 20, wherein the backflow hole 20 is arranged on the atomizing head 22 and the atomizing base 23, and the backflow hole 20 is communicated with the liquid accommodating cavity 1; the film further comprises a second film 33, and the second film 33 is arranged on the reflow hole 20; a second lancing assembly 34; the second piercing assembly 34 and the second membrane 33 should be positioned in a manner consistent with the positioning of the first membrane 31 and the first piercing unit described above, i.e., if the first piercing unit is positioned on the atomizing head 22, the second piercing assembly 34 should also be positioned on the atomizing head 22, as is the case in this embodiment.

When the inserting depth of the atomizing base 23 and the atomizing head 22 is a first depth, the second piercing assembly 34 does not pierce the second film 33;

Preferably, the first and second puncturing members 32 and 32 are hollow columns with pointed ends or puncturing bodies with pointed ends and cross-shaped cross sections; the choice of the hollow column or the piercing body is also related to the diameters of the liquid flow path 21 and the backflow hole 20, if the diameter is larger, the choice of the piercing body is suitable, and if the diameter is smaller, the choice of the hollow column is suitable because if the diameter is smaller, the piercing body is difficult to process on one hand, and on the other hand, the piercing body is easy to break during plugging, so the hollow column is more suitable for the situation with smaller diameter. If the diameter is large, it is said that the instantaneous liquid flow rate is very large, so that the use of the piercing body has a small effect on the flow rate resistance, whereas if the hollow column is used, the inner wall thereof has a certain thickness, which occupies the inner space of the liquid-returning hole 20.

In the present embodiment, the diameter of the return hole 20 is large, and the diameter of the liquid flow path 21 is small, so that the second puncturing member is a puncturing body, and the first puncturing member 32 is a hollow column.

the moving block is arranged in the atomizing base in a manner of relatively moving with the liquid flow path;

when the moving block is located at a preset position, the conducting hole is communicated with the liquid flow path;

and when the moving block is positioned at other positions except the preset position, the through hole and the liquid flow path are blocked.

9. The apparatus of claim 8, wherein the atomizing base has a receiving groove for receiving the moving block; an elastic component is arranged between the moving block and the accommodating groove; a fixing piece for fixing the moving block at a preset position is arranged on the atomizing base or on an external fixing unit;

when the moving block is located at a preset position, the elastic component is in a stretching or compressing state.

10. The apparatus of claim 8 or 9, wherein the moving block further comprises a backflow via hole; a backflow hole matched with the backflow conducting hole is formed in the spray head; the backflow hole is communicated with the liquid accommodating cavity;

when the blocking component moves to a preset position, the backflow via hole is communicated with the backflow hole;

when the blocking component moves to other positions except the preset position, the backflow through hole and the backflow hole are in a sealed isolation state.
