Description

Electronic cigarette atomizer device and electronic cigarette atomizer

Technical Field

The present invention relates to the technical field of atomization devices of electronic cigarette atomizers, and more particularly to an electronic cigarette atomization device and an electronic cigarette atomizer thereof.

Background technique

Existing electronic cigarettes generally include a battery assembly and an electronic cigarette atomizer. The electronic cigarette atomizer is provided with an atomizing device. The heating body in the atomizing device can heat the atomizing liquid and evaporate it to produce aerosol when powered on. The atomizing liquid, i.e., electronic cigarette liquid, is stored in the atomizer of the electronic cigarette, and the aerosol, i.e., electronic cigarette smoke, is produced and can be inhaled by users.

One of the electronic cigarette atomization devices currently available on the market includes a heating mesh structure, and the heating mesh is usually a curved single circuit path structure. This circuit structure has a single line type and cannot be laid on the atomization surface over a large area, resulting in uneven heating, small heat generation or atomization amount, slow atomization speed during smoking, that is, slow atomization response time, poor atomization effect, and heat concentration area may cause overheating and produce a burnt smell. In addition, this heating mesh, due to its single circuit path or thin path, or the mesh is weak, cannot independently support the guiding liquid upward, so it needs to be first fixed on the bracket or support sheet, and then the guiding liquid is supported upward by the bracket or support sheet. The heating mesh is limited to the heating function. In this case, the heating mesh needs to be installed or integrally made on the bracket or support body, which increases the manufacturing process of the product and increases the cost. At the same time, part of the heat of the heating mesh when working will be conducted to the bracket or support sheet, dispersing the heat energy, so that the heating mesh cannot directly conduct all the heat energy to the guiding liquid, reducing the atomization effect.

Best Mode for Carrying Out the Invention

The electronic cigarette atomizer device of the present invention is used to be assembled into an atomizer of an electronic cigarette to heat and atomize the cigarette liquid into aerosol or electronic cigarette smoke.

For the convenience of description, the electronic cigarette atomizer device and the electronic cigarette atomizer thereof of the present invention have the soft liquid-conducting sheet of the electronic cigarette atomizer device placed on top as shown in FIG. 1 , and the descriptions of “upper, lower, upper part, lower part, upper end, lower end, above, below, upward, downward” etc. concerning various components described herein all refer to the upper and lower positional relationship when the soft liquid-conducting sheet of the electronic cigarette atomizer device is placed on top.

Embodiments of the present invention

The present invention will be described in detail below through specific embodiments.

Example 1

As shown in FIGS. 1 to 9 , the electronic cigarette atomization device of the present embodiment comprises an atomization seat 1, an electrode column 2, a heating mesh sheet 3 and a soft liquid guide sheet 4, wherein the atomization seat 1 comprises an atomization chamber 10 which is concave downwards, a first air inlet through hole 11 is arranged at the bottom of the atomization chamber 10, two electrode columns 2 are arranged at two sides at the bottom of the atomization chamber 10, a bottom end of the electrode column 2 is penetrated through the bottom of the atomization seat 1, a first electrode through hole 12 for the electrode column 2 to pass through is arranged at the bottom of the atomization seat 1, and an upper end of the electrode column 2 is upwardly The heating mesh 3 is extended above the atomizing chamber 10 and is horizontally mounted on the upper ends of the two electrode columns 2. The heating mesh 3 includes conductive parts 31 on both sides and a heating part 32 in the middle. The conductive part 31 is connected to the upper ends of the electrode columns 2, and in particular, the conductive part 31 is welded to the upper ends of the electrode columns 2 to form a fixed connection. The heating part 32 is a mesh structure roughly in the shape of a honeycomb formed by a plurality of metal wires. The mesh of this structure has a certain tension or pressure resistance. The soft conductive liquid 4 is laid flat on the upper plane of the heating mesh 3. The bottom of the atomizing seat 1 is also provided with an annular air inlet groove 13 and a central air inlet groove 14. The annular air inlet groove 13, the central air inlet groove 14 and the first air inlet through hole 11 are interconnected. The soft liquid-conducting sheet 4 is made of soft materials such as organic cotton, inorganic cotton, glass fiber, ceramic fiber, etc. The soft material in the soft liquid-conducting sheet 4 is mainly composed of fibrous materials and has certain tiny gaps. The tiny gaps can penetrate and conduct the atomized liquid. The larger the gap size, the faster the liquid conduction speed. If the gap is too large, it is easy to cause leakage of the atomized liquid.

In this embodiment, the soft liquid-conducting sheet 4 is composed of a lower liquid-conducting sheet 41 and an upper liquid-conducting sheet 42. The average gap size of the upper liquid-conducting sheet 42 is larger than the average gap size of the lower liquid-conducting sheet 41, and the thickness of the upper liquid-conducting sheet 42 is larger than the lower liquid-conducting sheet 41. This is beneficial for the upper liquid-conducting sheet 42 to absorb and store the atomized liquid, while the lower liquid-conducting sheet 41 is used to penetrate and conduct the atomized liquid to the heating mesh 3 in an appropriate amount, and maintain a balance between maximum penetration conduction and leakage to avoid leakage of the atomized liquid.

In other embodiments, the conductive portion 31 does not need to be welded to the upper end of the electrode column 2, but the heating mesh 3 can be adhered to the bottom of the soft liquid-conducting sheet 4 to form a fixed connection. In this way, the heating mesh 3 and the soft liquid-conducting sheet 4 can still be supported by the electrode column 2 to support the conductive portion 31 upward.

As shown in Fig. 4 and Fig. 5, the heating part 32 of the heating mesh 3 includes two heating wire bodies 321 arranged symmetrically in the transverse direction, and the two adjacent heating wire bodies 321 have a zigzag path shape. A plurality of first heat-conducting wire bodies 322 are arranged transversely between different equipotentials on the two adjacent heating wire bodies 321, and a plurality of second heat-conducting wire bodies 323 are also arranged unidirectionally on the outer sides of the two heating wire bodies 321, respectively. The unidirectional arrangement means that only one end of the second heat-conducting wire body 323 is connected to the outer side of the heating wire body 321. Both the first heat-conducting wire body 322 and the second heat-conducting wire body 323 are not conductive because no current passes through them, and both are used to conduct and dissipate the heat from the heating wire body 321. The heating wire body 321 and the first heat-conducting wire body 322 and the second heat-conducting wire body 323 form a mesh wire body that is roughly evenly distributed, and gaps 324 are formed between the mesh wire bodies so that the mist generated after heating and evaporation can be dissipated. The evenly distributed mesh wire bodies and the gaps 324 formed between the mesh wire bodies make the heating wire body 321 heat evenly, and the heat of the heating wire body 321 is quickly and evenly distributed to the bottom surface of the entire soft conductive body 4 through the first conductive wire body 322 and the second conductive wire body 323. The heating wire body 321, the first conductive wire body 322, and the second conductive wire body 323 can be made of the same metal material in one piece.

The heating wire 321 and the first heat conductor 322 can both be made of a zigzag wire or a thin, elongated metal sheet. Since the two ends of the first heat conductor 322 are at the same potential, the first heat conductor will not conduct electricity even if it is made of metal material. The second heat conductor 323 has only one end connected to the side of the heating wire, so it is also not conductive. However, the first heat conductor 322 and the second heat conductor 323 can be used to quickly conduct and dissipate heat from the heating wire 21.

The above-mentioned welding and mesh structural characteristics of the heating mesh 3 of this embodiment enable the heating mesh 3 to have a strong tension to support the soft liquid-conducting sheet 4 above without deformation, and there is no need to set up a bracket or support body or support sheet to support or fix the heating mesh 3. Not only can one component be saved to reduce the production cost, but also all the heat generated by the heating mesh 3 can be conducted to the bottom of the soft liquid-conducting sheet 4, avoiding part of the heat from being conducted to the bracket or support body or support sheet in contact with the heating mesh 3 and reducing the atomization efficiency. In addition, in the heating part 32 of the heating mesh, there are evenly distributed heating wire bodies 321 and heat-conducting wire bodies 322 and 323 that diffuse heat to the bottom surface of the entire soft liquid-conducting liquid 4, which can make the heating more uniform and avoid the problem of dry burning and burning caused by heat concentration in the local area of the bottom surface of the soft liquid-conducting liquid 4, which leads to impure taste; and because the entire heating mesh 3 is heating and conducting heat at the same time, the heating area is large, the atomization of the atomized liquid is rapid and timely, and the atomization amount is large, which greatly improves the atomization effect.

Example 2

As shown in Figures 10 to 14, on the basis of the above embodiments, the electronic cigarette atomization device of this embodiment further includes a limiting bracket 5 connected to the atomizer seat 1, and a liquid conducting cavity 50 is provided in the middle of the bottom of the limiting bracket 5. The soft liquid conducting sheet 4 can be inserted into the liquid conducting cavity 50 from bottom to top. Two liquid conducting holes 51 are respectively provided on both sides of the center of the top of the limiting bracket 5, and the liquid conducting holes 51 are downwardly connected to the liquid conducting cavity 50, so that the atomized liquid can be guided downward from the top of the limiting bracket 5 through the liquid conducting holes 51 to the soft liquid conducting sheet in the liquid conducting cavity 50.

In the present embodiment, the electrode column 2 is configured to have a certain elasticity. Thus, when the electrode column 2 supports the heating mesh 3 and the soft liquid-conducting sheet 4 upward, the heating mesh 3 can be continuously pressed upward against the bottom of the soft liquid-conducting sheet 4 through the elasticity of the electrode column 2, and the soft liquid-conducting sheet 4 can be continuously pressed upward against the inner upper part of the liquid-conducting cavity 50. This can avoid leakage of the electronic cigarette liquid due to the gap between the soft liquid-conducting sheet 4 and the liquid-conducting cavity 50, and can also keep the heating mesh 3 close to the soft liquid-conducting sheet 4 to make the heating more sufficient and the heating effect better.

The bottom of the limiting bracket 5 is located on both sides of the liquid guiding cavity 50 and is provided with a first mist outlet through hole 52 upwardly, the middle part of the limiting bracket 5 is located above the liquid guiding cavity 50 and is provided with a mist outlet cavity 53 which is not connected to the liquid guiding cavity 50, and the top of the limiting bracket 5 is provided with a second mist outlet through hole 54 downwardly, and the first mist outlet through hole 52, the mist outlet cavity 53, and the second mist outlet through hole 54 are connected in sequence. The first mist outlet through hole 52, the mist outlet cavity 53, and the second mist outlet through hole 54 are isolated from the liquid guiding through hole 51 and the liquid guiding cavity 50 and are not connected, that is, the liquid passage and the airway are separated and work independently without causing leakage.

The limiting bracket 5 is provided with side wall openings 55 on both sides of the mist outlet cavity 53, and the side wall openings 55 allow the mist outlet cavity 53 to horizontally pass through the limiting bracket 5. The outer side wall of the limiting bracket 5 is provided with crisscross liquid collecting grooves 57, which are connected to the side wall openings 55, and gas blocking bumps 56 are formed between the liquid collecting grooves 57. When the atomization device of the embodiment of the present invention is applied to an electronic cigarette atomizer, the outer wall of the limiting bracket 5 is enclosed with the inner wall of the shell of the electronic cigarette atomizer, and the liquid collecting groove 57 is enclosed with the inner wall of the shell of the electronic cigarette atomizer to form a liquid collecting channel. When the electronic cigarette atomization device is working, the aerosol containing water vapor in the mist outlet chamber 53 is condensed into droplets and can overflow through the side wall opening 55 and be collected in the liquid collecting groove 57 or the liquid collecting channel, or the aerosol surrounds the outer wall of the limiting bracket 5 through the side wall opening 55, and the water vapor in the aerosol is blocked by the air blocking protrusion 56 and condensed into small droplets, which are collected in the liquid collecting groove 57 or the liquid collecting channel to prevent the droplets from being inhaled into the user's mouth and causing a bad smoking experience.

A convex buckle 58 is provided on the side wall of the limiting bracket 5 located below the side wall opening 55, and upwardly extending lugs 15 are provided on the two side walls of the atomizer seat 1. A buckle hole 150 is provided at a position corresponding to the convex buckle 58 on the lug 15. When the limiting bracket 5 is connected to the atomizer seat 1, the convex buckle 58 is just buckled into the buckle hole 150, so that the limiting bracket 5 and the atomizer seat 1 are connected and fixed up and down.

The top wall of the liquid conducting cavity 50 of the limiting bracket 5 is provided with an upwardly recessed liquid conducting groove 501 in the horizontal and vertical directions, and the liquid conducting groove 501 is connected with the liquid conducting through hole 51. When the soft liquid conducting sheet 4 is tightly attached to the top wall of the liquid conducting cavity 50, the atomized liquid can still quickly diffuse to the upper plane of the soft liquid conducting sheet 4 through the liquid conducting groove 501, so that the soft liquid conducting sheet 4 can absorb and conduct the atomized liquid faster, avoiding dry burning caused by untimely conduction of the atomized liquid.

Example 3

As shown in Figures 15 to 18, an electronic cigarette atomizer of the present embodiment has an electronic cigarette atomizer device A as in Example 2, and a nozzle shell 6 and a bottom cover 7. The nozzle shell 6 includes a suction port 61 provided at the upper end and an opening provided at the bottom end. The suction port 61 extends downward and is provided with a suction port tube 62. The electronic cigarette atomizer device A is sleeved in the nozzle shell 6 from the opening upward, and the second mist outlet hole 54 is upwardly connected to the suction port tube 62. A liquid storage chamber 63 is formed between the inner wall of the nozzle shell 6 above the electronic cigarette atomizer device A and the suction port tube 62. The bottom cover 7 is sleeved on the bottom end of the nozzle shell 6 and supports the electronic cigarette atomizer device A inwardly. The bottom cover 7 is enclosed with the bottom of the atomizer seat 1, and forms an air intake chamber 70 with the annular air intake groove 13 and the central air intake groove 14 provided at the bottom of the atomizer seat 1.

After the mouthpiece tube 62 of this embodiment is downwardly sleeved on the second mist outlet through hole 54, its bottom end portion further extends downward to the mist outlet chamber 53, so that the outer wall of the bottom end portion of the mouthpiece tube 62 and the inner wall of the mist outlet chamber 53 form an annular groove 531. When the atomized electronic cigarette smoke reaches the mist outlet chamber, the water vapor contained in the smoke can condense on the inner wall of the mist outlet chamber. The condensed water vapor accumulates in the annular groove 531, which can prevent the water vapor from being driven upward by the airflow and being sucked into the user's mouth, so that the user can inhale smoke with a good taste.

The bottom cover 7 is a cylindrical body, including a bottom plate 71 and a side wall portion 72. The side wall portion 72 is sleeved on the bottom outer wall of the nozzle shell 6. A second electrode through hole 73 is provided on the bottom plate 71. The bottom end of the electrode column 2 is exposed from the second electrode through hole 73. The electronic cigarette atomizer of this embodiment can be connected to an electronic cigarette battery rod to form an electronic cigarette. The battery rod is provided with an electrode that is in contact with the electrode column 2 so that the battery can supply power to the electronic cigarette atomizer. A second air inlet hole 74 is also provided on the bottom plate 71. When the electronic cigarette atomizer is working, the external gas enters the air inlet chamber 70 or the annular air inlet groove 13 and the central air inlet groove 14 provided at the bottom of the atomizer seat 1 through the second air inlet hole 74, and then enters the atomizing chamber 10 through the first air inlet hole 11; at the same time, the atomized liquid in the liquid storage chamber 63 enters the upper plane of the soft liquid guiding sheet 4 in the liquid guiding chamber 50 through the liquid guiding hole 51, and the soft liquid guiding sheet 4 absorbs the atomized liquid and then penetrates downward to conduct the heating mesh 3. The heating mesh 3 is powered on to generate heat, and the atomized liquid at the bottom of the soft liquid guiding sheet 4 is heated and evaporated into aerosol or electronic cigarette smoke. The electronic cigarette smoke is emitted into the atomizing chamber 10, and then discharged upward through the first mist outlet hole 52, the mist outlet chamber 53, the second mist outlet hole 54, the suction pipe 62 and the suction port 61 in sequence with the incoming air, and finally sucked into the user's mouth.

In other embodiments, the electronic cigarette atomizer device A as in the second embodiment can also be applied to disposable electronic cigarettes. Disposable electronic cigarettes generally integrate the electronic cigarette atomizer and the electronic cigarette battery rod, that is, on the basis of the third embodiment, the bottom cover 7 of the electronic cigarette atomizer is cancelled, and its mouthpiece shell 6 is integrated with the outer shell of the electronic cigarette battery rod, and the bottom end of the electrode column in the electronic cigarette atomizer device A is directly electrically connected to the positive and negative electrodes of the battery.
