(1) Isolation piece

An embodiment of the present disclosure provides a spacer for an atomizer, including a spacer body 2 and a traction piece 209, wherein a hollow channel is formed in the spacer body 2, and the hollow channel is used to accommodate the mist of the atomizer The main body of the spacer blocks the oil inlet hole of the atomization core in the first state, and exposes the oil inlet hole of the atomization core in the second state. The traction member 209 is used to drive the main body of the spacer 2 to slide, so that The spacer body slides from the first state to the second state. Wherein, when the spacer body is in the first state, the traction member is connected to the spacer body and seals the hollow passage; when the spacer body is in the second state, the traction member is detached from the spacer body, so that the hollow passage communicates with the outside world. Specifically, when the main body of the spacer is in the first state, the oil inlet hole is blocked, so that the oil inlet hole is isolated from the oil storage chamber described below, and the smoke oil in the oil storage chamber cannot enter the atomizing core through the oil inlet hole; When the main body of the spacer is in the second state, the oil inlet hole is exposed, so that the oil inlet hole communicates with the oil storage chamber, and the e-liquid in the oil storage chamber can enter into the atomizing core through the oil inlet hole. Before use, the spacer main body 2 can be sleeved outside the atomizing tube 3 of the atomizer by using its hollow passage to seal the oil inlet hole. When the user uses it, the tractor 209 can be used to pull the spacer main body 2 to slide to open the oil inlet hole. In this way, the spacer can seal the oil inlet hole, separate the air from the e-liquid, avoid problems such as oil leakage during storage or transportation, oxidative deterioration of the e-liquid intake, and prevent the heating element from being used for a long time before it is used. For the problem of shortened service life caused by contact with e-liquid, the main body of the spacer is moved to open the oil inlet hole through the traction piece during use, which is convenient and quick, and does not affect the user experience.

In some embodiments, the spacer body 2 and the traction member 209 are integrally formed. Alternatively, the spacer body 2 is integrally formed with the puller 209 as separate components connected to each other. Cutting grooves are provided at the junction of the spacer body 2 and the traction member 209 to separate the spacer body and the traction member at the junction, that is to say, the junction is easy to be broken.

In some embodiments, the traction member 209 includes a rod body 206 and a cover portion 500 arranged at one end of the rod body 206, the edge of the cover portion 500 is connected with the port of the hollow channel and seals the port of the hollow channel, and the cover portion 500 Cutting grooves 207 are provided at the joints between the edges of and the ports of the hollow channel. Overheating or overcooling during storage or transportation will cause the atomizer to expand with heat and contract with cold, and there will be gaps in the atomizer to avoid air leakage and oil leakage. The main body of the spacer is used to be sleeved on the peripheral wall of the mist outer tube. When the cover body seals the port of the hollow channel, it is equivalent to sealing the atomization tube, which is equivalent to sealing the entire air guide channel in the atomizer. When the user uses it, after the traction member is pulled off, the cover body is broken, and the air guide channel is opened, which does not affect the user's suction of the atomized aerosol.

In some embodiments, the spacer body 2 is formed with a limiting portion for limiting the sliding stroke of the spacer body 2 . The spacer main body 2 only slides within a certain stroke in the atomizer by using the limit part, and the spacer main body 2 does not leave the atomizer. After the traction piece 209 drives the spacer main body 2 to slide to the designated position, the spacer main body The limited part is limited to the designated position. In some examples, when force is applied again, the traction member 209 is broken and disengaged.

In some examples, a limiting protrusion protruding radially is formed on the outer periphery of the spacer main body 2, and the limiting protrusion serves as a limiting portion. Wherein, if the shape of the main body of the spacer is a straight cylinder, etc., the limiting boss can be directly protruded radially on the outer peripheral wall as the limiting part.

In another example, the spacer body 2 includes a first sleeve 202 and a second sleeve 200, the first sleeve is arranged between the traction member and the second sleeve, the first sleeve 202 is opposite to the second sleeve The diameter of 200 is reduced, and a limiting convex edge 203 is formed between the first sleeve 202 and the second sleeve 200, and the limiting convex edge serves as a limiting portion. The atomizer includes an oil reservoir, and one end of the oil reservoir is a smoking port, which protrudes downward from the edge of the smoking port to form an air duct. The outer wall of the air duct and the inner wall of the oil reservoir enclose an oil storage cavity. The state is located under the air guide tube. After sliding, the limit convex edge will abut against one end of the air guide tube to seal the oil storage chamber. Therefore, in addition to the position-limiting function, the position-limiting convex edge can also serve the purpose of sealing the oil storage chamber. Wherein, the first sleeve extends into the air guide tube, and the second sleeve is located under the air guide tube and in the oil storage chamber.

The traction member 209 includes a rod body 206 and a cover body 500 arranged at one end of the rod body 206, the edge of the cover body part 500 can be connected with the port of the first sleeve 202 and seal the port of the first sleeve 202, and the cover body Cutting grooves 207 are provided at junctions between the edge of the portion 209 and the port of the first sleeve 202 .

In another example, a limiting protrusion protrudes radially outward from the limiting protrusion 203 of the second sleeve 200 , and the limiting protrusion and the limiting protrusion 203 together constitute a limiting portion. By designing the limit boss at the limit convex edge 203, the limit part protrudes longer in the radial direction, the limit is more stable, the limit effect is better, and the effect of sealing the oil storage chamber is also better. it is good.

In some embodiments, at least one drag reducing boss 204 protruding radially is formed on the outer wall of the first sleeve 202 . Use the drag-reducing boss to reduce the contact area between the main body of the spacer and the atomizing tube, so that the main body of the spacer can move more smoothly, and avoid the phenomenon that the main body of the spacer has not slid to open the oil inlet hole and the traction piece is broken.

In some examples, at least one drag-reducing boss 204 is in the shape of a sheet and is arranged and distributed on the outer wall of the first sleeve 202 along the axial direction. In some other examples, at least one drag reducing boss 204 is distributed on the outer wall of the first sleeve 202 in a spiral shape. In some other examples, at least one drag reducing boss 204 is distributed on the outer wall of the first sleeve 202 in a cross shape. Preferably, each drag-reducing boss 204 is planar and arranged axially on the outer wall of the first sleeve 202 to facilitate production.

The uppermost drag-reducing boss 204 of the at least one drag-reducing boss 204 is inclined and slopes downward to the end. The atomizer tends to expand with heat and contract with cold under the condition of overcooling or overheating, resulting in a pressure difference inside and outside the atomizer, and the top drag-reducing boss is easily deformed by the pressure difference. Umbrella shape, even if there is a pressure difference to deform the sealing boss, there will be no gaps to leak air or oil.

When the main body of the spacer is moved and the traction piece is disconnected, the air groove and the air guide channel will be opened to ventilate the air groove, thereby balancing the air pressure in the oil storage chamber, and the oil inlet hole will enter the oil more quickly, preventing the heating element from being damaged due to insufficient oil inlet. Burnout problem. Therefore, when the atomizer is not in use, the sealing boss is used to seal the lower end of the air groove. Only when the atomizer is in use, the main body of the spacer is moved and the traction member is disconnected, the sealing boss leaves the original position, and the air groove is opened. When the sealing boss is in the initial position, the air groove is sealed to avoid oil leakage and air leakage.

In some other embodiments, the rod body 206 of the traction member 209 is formed with a radially protruding sealing boss 205 , the sealing boss is inclined and slopes downward to the end. At this time, the sealing boss is used to seal the upper end of the air groove, and can also further play the role of sealing the air guiding channel. Among them, the atomizer tends to expand with heat and contract with cold under the condition of overcooling or overheating, resulting in a pressure difference between the inside and outside of the atomizer. Since the sealing boss is at the top, it is designed to be inclined downward, roughly in the shape of an umbrella, even if There is no pressure difference to deform the sealing boss, and there will be no gap to cause air or oil leakage.
