FIELD OF THE INVENTION

The present invention particularly relates to an electronic cigarette.

BACKGROUND OF THE INVENTION

The existing electronic cigarette includes a housing, a support in the housing, a key PC board fixed on the support, and a suction nozzle at one end of the housing, and has the following disadvantages:

First, the suction nozzle is connected to the housing by thread tightening, and the suction nozzle is often rotated, so threads are easily worn to cause slipping, the connection method is unreliable, the use cost is increased, and the operation is not convenient.

Second, in order to increase the contact area of the hand operating the key PC board and avoid finger discomfort caused by the key, an electronic cigarette using a side panel of the housing as a key shell has appeared, wherein the bottom of the key shell is rotatably connected to the support through a shaft, a raised portion capable of abutting against the key PC board is provided at the bottom of the inner lateral surface of the key shell, and the key shell can rotate about the shaft and drive the raised portion to abut against the key PC board so as to control the circuit of the electronic cigarette to be closed. Since the side panel of the housing is used as the key shell, the force area of the key shell is large, the key shell is very easily deformed and deflected due to non-uniform force, the raised portion at the bottom of the key shell cannot abut against the key PC board, the switch of the key PC board cannot be effectively triggered, the operational reliability is low, and the user experience is poor.

Third, the phenomena of sucking liquid and scalding the mouth due to excessively high temperature of smoke often occur during smoking.

SUMMARY OF THE INVENTION

Aiming at the disadvantages of the prior art, the present invention provides an electronic cigarette, where the connection between a suction nozzle and a housing is reliable, the operation is convenient, the trigger efficiency of a key PC board is high, the reliability is high, and the problems of sucking liquid and scalding the mouth by smoke are solved, so the user experience is good.

In order to solve the above technical problems, the technical solution adopted by the present invention is as follows:

An electronic cigarette is provided, including a housing and a suction nozzle, the housing is provided with a support, wherein the electronic cigarette further includes a top cover capable of covering an opening of the housing, the suction nozzle is disposed at the top of the top cover, at least one end of the top cover is rotatably connected to the support, a clamping rib is disposed at the bottom of the top cover, and a locking mechanism connected to the clamping rib by locking is also disposed in the housing.

With the above structure, when the locking mechanism locks the clamping rib, the top cover covers the inside or outside of opening of the housing; and when the locking mechanism unlocks the clamping rib, the top cover can be opened to disconnect the suction nozzle from the housing. Since the locking mechanism is used to lock the top cover to realize the indirect connection between the suction nozzle and the housing, thread tightening is avoided, and the problem that threads are worn to cause slipping is also avoided. At the same time, the locking mechanism is used to lock or unlock the clamping rib, so the operation is convenient, the connection is reliable, and the cost is low. When the top cover is opened, an atomization assembly and the like can be put into the housing or taken out, so the operation is simple, convenient and reliable.

Further, an elastic mechanism for opening the top cover when the locking mechanism is separated from the clamping rib is also disposed in the housing.

With the above structure, when the locking mechanism unlocks the clamping rib, the elastic force of the elastic mechanism opens the top cover, so the operation is convenient.

As a preferred manner, at least one end of the top cover is rotatably connected to the support through a rotating shaft, the elastic mechanism includes a torsion spring between the support and the housing, and the torsion spring is sleeved outside the rotating shaft.

As a preferred manner, the locking mechanism includes a key handle, a transmission and a first spring, and the transmission has a buckling portion corresponding to the clamping rib; the transmission and the first spring are disposed on the support, one end of the key handle is connected to the transmission, and the other end of the key handle passes through the housing and is exposed.

With the above structure, when the top cover seals the opening of the housing, the buckling portion and the clamping rib are locked with each other; and when the key handle is pushed inward, the key handle drives the transmission to move inward and causes the buckling portion and the clamping rib to be unlocked, and the key handle compresses the first spring. When the key handle is pressed by an external force, the transmission moves toward the inside of the electronic cigarette along with the key handle, then the buckling portion on the transmission is separated from the clamping rib on the top cover, the locking portion is unlocked from the clamping rib, the top cover flips under the torsion of the torsion spring, that is, the top cover is opened by flipping, and the atomization assembly and the like can be taken out from the housing and be replaced, or the receiving chamber for placing the atomization assembly can be cleaned, thereby improving the user experience. When the key handle is released, the key handle and the transmission are reset under the restoring force of the first spring. When the top cover is closed, the buckling portion locks the clamping rib to stabilize the top cover, thereby preventing the atomization assembly from automatically popping up to affect the smoking effect.

As a preferred manner, two clamping ribs are symmetrically disposed at the bottom of the top cover, and two locking mechanisms are correspondingly disposed in the housing.

The locking mechanisms are disposed on two sides of the electronic cigarette, each key handle is disposed independently, and when a user needs to open the top cover to replace the atomization assembly, the top cover can be opened by pressing the key handles on two sides at the same time, which is in line with human operating habits, so the operation is simple and convenient, the force is uniform, and the top cover can be opened without being stuck or locked.

Further, a side panel of the housing is a key shell detachably connected to the housing, the bottom of the key shell is rotatably connected to the support through a key shaft, the upper part of the key shell is connected to a linkage block on the support by transmission, the linkage block is provided with a raised portion capable of abutting against a key PC board, and a second spring is disposed between the linkage block and the key PC board.

With the above structure, since the key shaft connected to the upper part of the key shell by transmission is provided, the force applied to the key shell is concentrated on a movable member, and the movable member abuts against the key PC board to turn on the circuit. At the same time, according to the principle of leverage, this control method not only concentrates the force, but also saves time and effort, is better in hand feel, and enhances the user experience.

As a preferred manner, two first grooves are symmetrically formed on two inner sides of the key shell, the linkage block is provided with two protrusions corresponding to the first grooves, and the support is provided with two second grooves corresponding to the protrusions.

Two first grooves are symmetrically formed on two inner sides of the key shell, the linkage block is provided with two protrusions corresponding to the first grooves, and the protrusions move in corresponding second grooves. The first grooves cooperate with the protrusions to prevent the key shell from being disconnected from the linkage block. At the same time, because the first groove and protrusion matching structures are symmetrically arranged, when the key shell is subjected to an external force, the key PC board is stressed uniformly, the hand feel of the key is improved, more effort is saved, the efficiency of abutting against the switch on the key PC board is higher, and the phenomenon of locking due to uneven force is avoided.

Further, a fixed block is also disposed on the support, one of the two second grooves is an oval groove formed in the support, and the other one of the two second grooves is an oval groove formed by a semi-oval groove in the fixed block and a semi-oval groove in the support.

An oval groove is defined by the fixed block and the support, which is convenient for assembly.

Further, the electronic cigarette includes an atomization assembly, the support is provided with a receiving chamber for placing the atomization assembly, a first electrode electrically connected to one pole of the atomization assembly is disposed at the bottom of the receiving chamber, and a second electrode electrically connected to the other pole of the atomization assembly is disposed at the bottom of the receiving chamber.

When the atomization assembly is placed in the receiving chamber and the top cover is closed, two poles of the atomization assembly are in contact with the first electrode and the second electrode respectively, and the working circuit is connected.

Further, the top cover abuts against the first electrode and the second electrode through the atomization assembly.

The atomization assembly of the electronic cigarette is squeezed and locked by the top cover, so that the atomization assembly is electrically connected to the first electrode and the second electrode in the support stably.

Further, a third spring is also disposed in the housing, one end of the third spring abuts against the first electrode, and the other end of the third spring abuts against the support.

Further, a fourth spring is also disposed in the housing, one end of the fourth spring abuts against the second electrode, and the other end of the fourth spring abuts against the support.

After the top cover is locked by the locking mechanism, the top cover compresses the third spring corresponding to the first electrode through the atomization assembly, and the top cover compresses the fourth spring corresponding to the second electrode through the atomization assembly, so that the atomization assembly automatically pops up after the top cover is opened, the operation is simple, and the atomization assembly is convenient to be take out or be mounted. At the same time, since the atomization assembly and the first electrode or the second electrode are in flexible contact, rigid contact is avoided, and the conductive reliability is high.

As a preferred manner, the atomization assembly includes a shell; a liquid chamber, a liquid guiding mechanism and an ultrasonic atomization sheet are disposed in the shell; the liquid chamber is communicated with an atomization surface of the ultrasonic atomization sheet through the liquid guiding mechanism, one electrode layer of the ultrasonic atomization sheet is electrically connected to the first electrode, and the other electrode layer of the ultrasonic atomization sheet is electrically connected to the second electrode.

Further, a first tube is also disposed in the shell, the first tube has a baffle portion at one end, the liquid chamber is on one side of the baffle portion, the liquid guiding mechanism is on the other side of the baffle portion, and the liquid chamber is communicated with the liquid guiding mechanism only through a first through hole in the baffle portion.

Because the liquid chamber is communicated with the liquid guiding mechanism only through the first through hole in the baffle portion, liquid is guided relatively slow, which can avoid the phenomenon of liquid immersion of the ultrasonic atomization sheet when the electronic cigarette is not used for a long time, the starting speed of the ultrasonic atomization sheet is improved, and the phenomenon that the user easily sucks the liquid during smoking is avoided.

Further, a second tube is disposed in the first tube, the other end of the first tube and one end of the second tube are both connected to one end of the shell through a connector, a cavity is formed in the connector, the cavity is communicated with the outside through a second through hole in the connector, a channel is formed between the first tube and the second tube, and the cavity, the channel, the atomization surface of the ultrasonic atomization sheet, the inner cavity of the second tube, and the suction nozzle are communicated in sequence.

With the above structure, since the cavity is disposed at the air outlet end of the second tube, the air in the cavity will absorb part of the heat of airflow flowing through the air outlet end of the second tube, thereby reducing the temperature of the airflow flowing out from the suction nozzle, and preventing scalding the mouth; at the same time, the air in the cavity reaches the atomization surface of the ultrasonic atomization sheet through the channel, thereby preventing cold air from directly reaching the atomization surface of the ultrasonic atomization sheet, and improving the working efficiency and atomization amount of the ultrasonic atomization sheet.

Compared with the prior art, the present invention has the advantages that the connection between the suction nozzle and the shell is reliable, the operation is convenient, the efficiency of triggering the key PC board is high, the reliability is high, the time and effort are saved, the starting speed of the ultrasonic atomization sheet is high, the working efficiency is high, the smoke is stable, suction of liquid or mouth scald is avoided, and the smoke taste and the user experience are good.
