Description

Electronic aerosolizer and electronic cigarette Technical field

The invention particularly relates to an electronic cigarette atomizer and the electronic cigarette.

Background technique

The existing electronic atomizers have the following disadvantages:

1. When sealing the oil hole between the oil tank and the atomized cotton, it usually depends on the relative rotation of the connecting sleeve and the outer sleeve. Because the connecting sleeve and the outer sleeve are metal parts, when two metal parts are required to rotate together, The dimensional accuracy requirements for the two metal parts are very high, and assembly is also cumbersome at the same time, so the production time is long and the production cost is high, and the sealing effect is not good, and there is a risk of oil leakage and oil absorption.

2. Rotary gas adjustment process often drives the oil injection cap to rotate, causing the oil injection cap to be opened by mistake, which causes the e-liquid to leak out or the oil tank to lose negative pressure. As a result, the e-liquid from the oil tank to the atomized cotton is too fast and smoke is drawn. The condition of the oil. 3. When the rotary air regulating structure rotates to two extreme positions, it will inevitably drive the oil injection cap to rotate, which will cause the e-liquid to leak out or the oil tank to lose negative pressure. As a result, the e-liquid will be led from the oil tank to the atomized cotton too quickly, causing suction. To the case of e-liquid.

Summary of the Invention

In the existing electronic atomizer, the oil inlet hole is sealed by the relative rotation of two metal parts, so the production time is long and the production cost is high, and the sealing effect is not good, and there is a risk of oil leakage and oil absorption. It will cause the oil filling hole to open, resulting in oil leakage and oil suction. An object of the present invention is to provide an electronic cigarette atomizer and the electronic cigarette, which have short production time, low production cost, and good sealing effect. It is independent of the oil injection action and does not affect each other. It does not cause the accidental opening of the oil filler cap during gas adjustment, avoids oil leakage and smoke oil, and has a good user experience.

To solve the above technical problems, the technical solutions adopted by the present invention are:

An electronic atomizer includes a casing, and a top cover is provided on the top of the casing. An oil tank, an atomizing member, a connecting sleeve, and an atomizing cotton connecting the oil silo and the atomizing member are provided in the casing. The connecting sleeve is provided for communication. The lower part of the connection sleeve is set outside the upper section of the outer sleeve of the oil tank and the oil inlet of the atomized cotton. The outer sleeve is set outside the atomized cotton. A first passage for connecting the oil inlet and the atomized cotton is provided on the outer sleeve. Oil hole; the top cover can drive the connecting sleeve to rotate in the circumferential direction and make the oil inlet hole open or close; its structural feature is also used to provide buffer for the force between the connecting sleeve and the outer sleeve when the connecting sleeve rotates in the circumferential direction Functioning cushioning mechanism.

With the above structure, since the buffer mechanism provides a buffering force for the force between the connecting sleeve and the outer sleeve when the connecting sleeve rotates in the circumferential direction, the rigid connection between the connecting sleeve and the outer sleeve is not completely rigid, so the connecting sleeve and the outer sleeve are not completely rigid. The requirements for the dimensional accuracy of the fitting of the pipe are low, the assembly is convenient, the production time is short, the production cost is low, and the sealing effect is good, avoiding the risk of oil leakage and oil absorption.

As a first preferred mode, the buffer mechanism includes a seal, and an outer periphery of the seal is provided with a locking groove that is engaged with the first oil hole, and the seal is provided with a first portion opposite to the first oil hole. The two oil passing holes and the second oil passing hole communicate with the first oil passing hole and the atomized cotton.

The seal is clamped and fixed in the first oil hole of the outer casing, so when the top cover rotates and drives the connection sleeve to rotate with respect to the outer casing, the seal does not rotate, and the oil inlet hole is sealed only by the rotation of the connection sleeve, preventing the oil inlet during oil injection. The oil hole and the atomized cotton communicate with the oil leakage. Due to the cushioning effect of the seal, the connection sleeve and the outer sleeve are not completely rigid. Therefore, the dimensional accuracy of the connection sleeve and the outer sleeve is low, the assembly is convenient, the production time is short, the production cost is low, and the sealing effect is Better to avoid the risk of oil leakage and oil absorption.

Further, a convex ring is provided on the seal along the outer periphery of the second oil hole toward the inner side wall of the connecting sleeve.

Due to the interference fit between the convex ring and the connecting sleeve, when the oil is injected, the convex ring abuts on the inner wall of the connecting sleeve, which can more reliably seal the oil inlet hole.

Further, an inner sleeve is provided in the connecting sleeve, and the outer sleeve is sleeved outside the inner sleeve. The atomized cotton is cup-shaped, and the side wall of the atomized cotton is sandwiched between the inner sleeve and the outer sleeve. The inner side of the seal is in contact with the outer wall of the atomized cotton.

Since the sealing member abuts on the atomized cotton, the atomized cotton and the inner sleeve are more fully contacted, the oil passage is smooth and reliable, and the atomized cotton is prevented from generating wrinkles during the assembly process.

As a second preferred manner, the buffer mechanism includes a seal sleeved on the outside of the connection sleeve, a second oil hole is formed on the seal, and the seal is provided along the outer periphery of the second oil hole. An inner convex ring protruding into the oil inlet hole, the end surface of the inner convex ring abuts the outer side wall of the outer casing.

With the above structure, the seal is sleeved outside the connection sleeve, so that the seal is rotated together when the connection sleeve rotates, thereby opening or closing the oil inlet hole on the connection sleeve, preventing the oil inlet hole from communicating with the atomized cotton during oil injection. And oil leakage occurs. Since the inner convex ring is inserted into the oil inlet hole of the connecting sleeve, and the end face of the inner convex ring is in contact with the outer side wall of the outer sleeve, the sealing effect can be ensured. The dimensional accuracy of the connection sleeve and the outer sleeve is low, the assembly is convenient, and the production man-hour is short. Moreover, the production cost is low, and the sealing effect is better, and the risks of oil leakage and oil absorption are avoided. In addition, the seal is lightly abraded and feels good without jamming.

Further, the inner convex ring passes through the oil inlet hole and abuts against a side wall of the oil inlet hole to prevent the inner convex ring from being deformed during the rotation process and ensure a sealing effect.

Further, an inner sleeve is provided in the connecting sleeve, and the outer sleeve is sleeved outside the inner sleeve. The atomized cotton is cup-shaped, and the side wall of the atomized cotton is sandwiched between the inner sleeve and the outer sleeve.

Further, the housing is provided with an air inlet channel and an air outlet channel, and the suction nozzle is sleeved outside the top cover and can be rotated relative to the top cover. The air inlet, the air inlet channel, the atomizing member, the air outlet channel, the air outlet, and the suction nozzle are in this order. The communication also includes an inverse mechanism for preventing the suction nozzle from moving axially with respect to the top cover; a movable part and an internal thread sleeve are arranged in the top cover, and the lower part of the side wall of the movable part is screwed with the internal thread sleeve; the suction nozzle rotates Drive the movable part to rotate relative to the internal thread sleeve and move axially along the top cover; the movable part is provided with an air vent that connects the air inlet and the air inlet channel. When the movable part moves axially along the top cover, the internal thread cover The inner wall is out of place to cover the air hole to adjust the amount of intake air entering the air intake channel; the top cover is provided with an oil injection hole for filling oil into the oil tank, and the top cover is matched with the internal thread sleeve.

With the above structure, since the suction nozzle and the top cover are engaged with each other, and the suction nozzle and the top cover are buckled and locked, the suction nozzle can be prevented from moving axially relative to the top cover. When the suction nozzle is rotated, the movable member moves axially under the driving of the suction nozzle, so as to adjust the area of the air hole blocked by the internal thread sleeve. The air hole on the movable member moves out of position relative to the air inlet, increasing or decreasing the unit. The air flow passing through the pores in a time, easy to adjust, and good sealing performance. Due to the large holding area of the suction nozzle, the rotation force during the rotation can be easily controlled, and the operation is simple and reliable. At the same time, due to the clearance between the top cover and the internal threaded sleeve, the top cover will not rotate during the air adjustment process, so the oil injection hole will not be opened during air adjustment, to avoid oil leaks in the oil tank or excessive oil supply and smoke oil. Even if the nozzle is rotated to the extreme position during gas adjustment, the top cover will not be driven to rotate, and the oil hole will not be accidentally opened during gas adjustment.

Further, the top cover and the connection sleeve are riveted by a pressure ring. The top cover drives the connection sleeve to rotate circumferentially through the pressure ring. When the oil injection hole is opened, the oil inlet hole is misaligned with the first oil hole; when the oil injection hole is closed, The oil inlet hole is aligned with the first oil hole.

With the above structure, the top cover and the connecting sleeve are integrated into one by the pressure ring riveting, so that the rotation of the top cover can drive the connecting sleeve to rotate at the same time, so that the oil inlet hole can be closed when the top cover rotates to the opening of the oil filling hole to avoid the suction Smoke oil.

Further, the top cover is provided with a first limit step, an internal thread sleeve is placed on the first limit step, and the pressure ring is provided with a first clamping position for pressing the first limit step to limit the position. A step, a second clamping step for pressing the second limit step on the internal thread sleeve to press the limit.

With the above structure, the internally threaded sleeve is axially fixed by the first clamping step on the pressure ring, and the internally threaded sleeve can only rotate relative to the top cover in the circumferential direction. Therefore, when the top cover is filled with oil, the internal thread sleeve does not rotate, so it does not affect the air intake. Oiling and gas adjustment are independent of each other and do not affect each other.

Further, the outer wall of the connecting sleeve is provided with a limiting outer plane for limiting the circumferential rotation of the top cover relative to the connecting sleeve, and the inner wall of the top cover is provided with a limiting inner plane that cooperates with the limiting outer plane.

The outer wall of the connecting sleeve is cut to a limited outer plane, which cooperates with the limiting inner plane on the top cover, which can further limit the rotation of the top cover relative to the connecting sleeve, and ensure that the oil inlet hole is closed during oil injection.

Further, the bottom of the internally threaded sleeve is provided with at least two clamping grooves for restricting the circumferential rotation of the internally threaded sleeve, and the oil tank is provided with a card parallel to the electronic cigarette axis and matching with the clamping groove. Position post.

The locking post cooperates with the locking groove to limit the circumferential rotation of the internally threaded sleeve, so that the internally threaded sleeve cannot rotate when the suction nozzle is turned to adjust the air, so that the oil injection action and the gas adjustment action are absolutely separated without affecting each other.

In a preferred manner, at least two convex ribs parallel to the axis of the nozzle are uniformly arranged in the circumferential direction of the inner wall of the suction nozzle, and the outer wall of the movable member has positioning surfaces corresponding to the ribs on a one-to-one basis.

The convex rib and the positioning surface cooperate with each other to realize the rotation linkage effect.

Further, an air inlet pipe is provided in the housing, and the inner cavity of the air inlet pipe forms the air inlet passage; the air inlet end of the air inlet pipe is connected with the movable member, and the air outlet end of the air inlet pipe is opposite to the atomizing member. .

Because the air inlet end of the air inlet pipe is connected to the movable part, the movable part will drive the air inlet pipe to move during the movement process, so that the relative position of the air outlet end of the air inlet pipe and the atomizing part is changed. When the air intake volume is adjusted to be small, the distance between the air outlet end of the intake pipe and the atomizing part is relatively short, so the impact force of the air flow is large, so the smoke emission effect is good, and the smoke concentration will not be reduced while affecting the use.

Further, the inside of the vent hole on the top of the suction nozzle has a ring portion extending toward the inside of the suction nozzle, which can prevent the condensed smoke oil from being sucked out.

Further, the movable member has a cylindrical portion opposite to the vent hole. The cylindrical part can play the role of drainage, which can effectively help the condensed e-liquid at the nozzle to return, and alleviate the condensation of e-liquid at the nozzle.

As a preferred manner, the top of the cylindrical portion is a sharp-edged tip, and the drainage effect is better.

Based on the same inventive concept, the present invention also provides an electronic cigarette, including the electronic cigarette atomizer.

Compared with the prior art, the production process of the invention is short, the production cost is low, and the sealing effect is good; the oil injection hole will not be opened during gas adjustment, and the gas adjustment and oil injection actions are independent of each other without affecting each other, and there will be no mistakes in gas adjustment. The phenomenon of opening the oil cap to avoid oil leakage and smoking smoke, the user experience is good.

detailed description

Example one

As shown in FIG. 1 to FIG. 9, the first embodiment of the electronic cigarette atomizer includes a housing 8. A top cover 9 is provided on the top of the housing 8, and an oil tank 12, an atomizing member 3, a connection sleeve 22, and a communication oil tank are provided in the housing 8. 12 and the atomized cotton 14 of the atomizing member 3, an oil inlet 2201 for connecting the oil tank 12 and the atomized cotton 14 is provided on the connecting sleeve 22, and the lower section of the connecting sleeve 22 is sleeved outside the upper section of the outer sleeve 24, and the outer sleeve 24 It is sleeved outside the atomized cotton 14, and a first oil passage 2401 for connecting the oil inlet hole 2201 and the atomized cotton 14 is provided on the outer sleeve 24; the top cover 9 can drive the connecting sleeve 22 to rotate in the circumferential direction and make the inlet The oil hole 2201 is opened or closed; it also includes a buffer mechanism for providing a buffering effect for the force between the connection sleeve 22 and the outer sleeve 24 when the connection sleeve 22 rotates in the circumferential direction.

The second oil passing hole 4501 opposite to the oil hole 2401 is connected to the first oil passing hole 2401 and the atomized cotton 14. The sealing member 45 is made of silicone.

The seal 45 is snapped and fixed in the first oil hole 2401 of the outer sleeve 24. Therefore, when the top cover 9 rotates and drives the connection sleeve 22 to rotate relative to the outer sleeve 24, the seal 45 does not rotate, and only the connection sleeve 22 is rotated to seal the inlet. The oil hole 2201 prevents oil leakage between the oil inlet 2201 and the atomized cotton 14 during oil injection. Due to the cushioning effect of the seal 45, the connection sleeve 22 and the outer sleeve 24 are not completely rigid. Therefore, the dimensional accuracy of the connection sleeve 22 and the outer sleeve 24 is low, the assembly is convenient, the production time is short and the production is short. The cost is low and the sealing effect is better, avoiding the risk of oil leakage and oil absorption.

A convex ring 4503 is provided on the seal 45 along the outer periphery of the second oil hole 4501 toward the inner wall of the connecting sleeve 22.

Due to the interference fit between the convex ring 4503 and the connecting sleeve 22, the convex ring 4503 abuts on the inner side wall of the connecting sleeve 22 during oil filling, which can more reliably seal the oil inlet hole 2201.
