Description

Technical Field

[0001] The present invention relates to the field of electronic heating atomization devices, and in particular to an electronic heating atomization device with multi-channel liquid supply. Background Art

[0002] Electronic heating atomization technology is a method of using electricity to heat the atomizing liquid to bring it to a boiling point to produce an aerosol composed of a mixture of steam and air. Electronic atomization devices are widely used in the field of electronic cigarettes. Its working principle is to conduct the atomized liquid from the liquid storage end to the atomizing surface located in the air flow channel through the capillary pores inside the liquid-conducting material. A heating element is provided on the atomizing surface. When the heating element is powered, the heating element on the atomizing surface will generate heat due to the thermal effect of the resistor, heating the atomizing liquid to a boiling point and producing atomized steam. The atomized steam and the air entering the atomizer are mixed to form an aerosol substance, which is commonly known as smoke. The continuous atomization process requires a continuous supply of liquid through the liquid-conducting material, but it cannot be too much. Too much liquid will easily leak, so it is more important to ensure that the liquid is adequately supplied.

[0003] Usually, liquid enters from both ends of the liquid-guiding parts made of liquid-guiding materials. The liquid-guiding parts conduct the liquid from the liquid storage tank to the heating element for heating and atomization. Since the liquid is transferred from both ends to the middle through the capillary action of the liquid-guiding parts, the liquid reaches some parts of the liquid-guiding parts far away from the two ends, or the density of some parts of the liquid-guiding parts is different, which causes the liquid to reach these parts at a slower speed, resulting in the heating element being overheated due to insufficient liquid supply, causing dry burning and other problems, affecting the taste of the smoke.

The second liquid guide 22 with a liquid conducting function is equivalent to a second liquid supply channel, which is used to conduct liquid to the position where the first liquid guide 21 has insufficient liquid. This can effectively avoid the problem of the heating element being overheated or even burning dry due to insufficient liquid supply, improve the taste of the smoke, and enhance the user experience.

The first liquid-conducting liquid 21 is installed on the mounting base 4 first, and the second liquid-conducting liquid 22 is installed on the mounting base 4 later, pressing the first liquid-conducting liquid 21. The heating element 23 and the contact area between the first body portion 211 and the second body portion 221 are located in the ventilation cavity 43. The "pressing" here is to achieve contact between the first and second liquid-conducting liquids, thereby enabling the second liquid-conducting liquid to transfer liquid to the first liquid-conducting liquid. The "pressing" can be light or firm, as long as the two are in contact.

[0071] More preferably, see Figure 2-7 The liquid storage structure 11 is arranged above the mounting base 4, the first liquid guide 21 and the second liquid guide 22 are installed on the mounting base 4 from the upper side, and the second liquid guide 22 is arranged above the first liquid guide 21.

Furthermore, the second liquid-conducting material 22 is laterally overlapped and in contact with the first liquid-conducting material 21, with both ends also in contact with the liquid storage structure 11. Compared to existing technologies, this increases the liquid-conducting rate by 100%, better meeting the liquid supply requirements during atomization.

[0076] In embodiments where the first liquid guiding element 21 and the second liquid guiding element 22 are separate entities, the second liquid guiding element 22 is preferably made of fiber, such as cotton or linen, because it is relatively soft and easy to assemble.

One side of the opening of the inner shell 3 is combined with the mounting base 4 and covers the heating element 23, the first liquid-conducting liquid 21, and the second liquid-conducting liquid 22. The first liquid-conducting liquid 21 and the second liquid-conducting liquid 22 extend into the liquid storage structure 11 formed between the mounting base 4 and the outer shell 1. The mounting base 4 is provided with a first positioning groove 41 matching the first liquid-conducting liquid 21 and a second positioning groove 42 matching the second liquid-conducting liquid 22, for achieving positioning of the first liquid-conducting liquid 21 and the second liquid-conducting liquid 22. Further preferably, the mounting base 4 is provided with a ventilation cavity 43 opening toward one side and an air inlet 44 connected to the ventilation cavity 43, and the inner shell 3 is also provided with an air outlet 33 connected to the internal cavity. The heating element 23, the first liquid guide 21 and the second liquid guide 22 are located in the ventilation cavity 43. The airflow entering the ventilation cavity 43 from the air inlet 44 carries the smoke formed by heating and atomization by the heating element 23, enters the air outlet channel 12 through the air outlet 33, and then flows out of the electronic heating atomization device.

[0080] Preferably, the liquid storage structure is a liquid storage tank arranged in the outer shell 1 or a liquid storage part made of absorbent material. The liquid storage tank is a hollow cavity, and the liquid storage absorbs and stores the liquid through its own absorbency. For example, the liquid storage part can be liquid storage cotton or a ceramic part with numerous micropores inside.

[0081] Preferably, when assembling the electronic heating atomizer device, the heating element 23, the first liquid-conducting element 21, and the second liquid-conducting element 22 are mounted on the mounting base 4. The mounting base 4 and the inner shell 3 secure the first liquid-conducting element 21 and the second liquid-conducting element 22. After the inner shell 3 and the atomizer core 2 are assembled, the first seal 71 and the second seal 72 are installed, and then the inner shell 3 and the atomizer core 2 are installed together into the outer shell 1. The air outlet passage 12 leads to the atomizer core 2. The first seal 71 seals the air outlet passage 12 with the inner shell 3, and the second seal 72 seals the mounting base 4 with the outer shell 1. The bottom shell 5 and the electrode 6 are then installed. The electrode 6 is electrically connected to the heating element 23 of the atomizer core 2, and the electronic heating atomizer device is formed. The vapor generated by the atomizer core 2 flows out of the electronic heating atomizer device through the air outlet passage 12. The electrode 6 is used to supply power to the heating element 23 from an external power source.

[0082] In summary, the electronic heating atomization device includes a first liquid guide 21 and a second liquid guide 22. The second liquid guide 22 can be arranged at a location where the first liquid guide 21 is insufficient. The first liquid guide 21, which has a liquid conduction function, is equivalent to a first liquid supply channel for conducting liquid to the heating element 23. The second liquid guide 22, which has a liquid conduction function, is equivalent to a second liquid supply channel for conducting liquid to the location where the first liquid guide 21 is insufficient. This can effectively avoid the problem of the heating element being overheated or even burning dry due to insufficient liquid supply, improve the taste of the smoke, and enhance the user experience. The first liquid guide 21 and the second liquid guide 22 can be separate independent entities. After both are installed in the electronic heating atomization device, the first liquid guide 21 contacts the second liquid guide 22, and the second liquid guide 22 replenishes the liquid to the central area of ​​the first liquid guide 21. The first liquid guide 21 and the second liquid guide 22 can also be integrated. Both are made into an integrated part in advance and then installed in the electronic heating atomization device. The first liquid guide 21 is connected to the second liquid guide 22, and the second liquid guide 22 replenishes the liquid to the central area of ​​the first liquid guide 21.
