[0041] The atomizer with an offset atomization core described in the present invention refers to a part of an electronic atomization device, which can be connected to a battery assembly to form a small electronic atomization device. This small electronic atomization device can be specifically used as an electronic cigarette for heating and atomizing tobacco liquid, or as a medical atomization device for heating and atomizing medicinal liquid or herbal essence, etc.

[0042] For the convenience of the following description, as shown in FIG2 , the housing of the atomizer is placed vertically with the mouthpiece 10 facing upward. The descriptions of “upper, lower, upper part, lower part, upper end, lower end, above, below, left and right” regarding the various structural components in the atomizer with an offset atomizing core described herein all refer to the positional relationships of the various structural components when the atomizer is placed vertically with the mouthpiece 10 facing upward. Modes for Carrying Out the Invention

[0043] The present invention will be described in detail below with reference to the accompanying drawings. Example 1:

[0044] As shown in Figures 1-3, an atomizer with an offset atomizer core according to an embodiment of the present invention comprises a housing 1 and an atomizer assembly 9. The housing 1 includes a mouthpiece end 11 and a connection end 12. The mouthpiece end 11 is provided with a suction port 10, which extends downwardly and is provided with an atomizer pipe 13. The connection end 12 is provided with an opening 14. The atomizer assembly 9 is inserted through the opening 14 and is sleeved onto the lower inner wall of the housing 1. The atomizer assembly 9 comprises an atomizer seat 2, an atomizer core 3, and a base 4. The atomizer seat 2 and the base 4 are connected vertically. The bottom end of the atomizer pipe 13 is connected to the upper portion of the atomizer assembly 9. The upper portion of the atomizer seat assembly 9, the inner wall of the housing 1, and the outer wall of the atomizer pipe 13 enclose a cavity for storing atomized liquid, forming a liquid storage chamber 15. The housing 1 is connected to a battery assembly (not shown) via the connection end 12 to form an electronic atomization device. The atomizer core 3 can absorb, penetrate, and conduct the atomized liquid to the heating surface from one side, and evaporate and atomize the atomized liquid into steam, aerosol or electronic cigarette smoke after being powered on and heated.

[0045] The inner wall of the shell 1 above the atomizer assembly 9 is provided with an inwardly protruding axial rib 16. The axial rib 16 is axially arranged on the inner wall of the shell 1 from top to bottom and is integrally formed with the shell 1. The bottom end of the axial rib 16 abuts against the upper end plane 20 of the atomizer seat 2.

[0046] An annular groove 17 is provided on the outer wall of the shell 1 at the upper part of the connection end 12, and a sealing ring 7 is provided in the annular groove 17. The sealing ring 7 is used for sealing when the shell 1 is connected to the battery assembly.

[0047] As shown in Figure 4, the atomizer core 3 of the present embodiment comprises a soft liquid-conducting layer 31, a porous ceramic liquid-conducting layer 32, and a heating layer 33, connected in sequence from top to bottom. The soft liquid-conducting layer 31 can be made of cotton, and the heating layer 33 can be composed of a heating resistor material such as a metal heating wire, a heating sheet, or a heating film. Atomized liquid is conducted downward from the soft liquid-conducting layer 31 and the porous ceramic liquid-conducting layer 32, penetrating the lower surface of the porous ceramic liquid-conducting layer 32. When the heating layer 33 is energized and heated, the atomized liquid is heated and atomized into aerosol or electronic cigarette mist. The heating layer 33 has notches, through-holes, or pores to allow the atomized liquid to evaporate into aerosol or electronic cigarette mist and escape through the heating layer 33. Electrode layers (not shown) are also provided on both sides of the bottom of the heating layer 33. The top of the columnar electrode 5 of the present invention abuts against these electrode layers, and close contact between the two ensures electrical connection of the heating layer 33. The columnar electrode 5 also provides upward support and fixation for the atomizer core 3.

[0048] As shown in Figures 5 to 9, the present invention has an atomizer with an offset atomizing core. The upper end of the atomizing seat 2 is provided with an upper end plane 20, and a vertical mist outlet through-hole 21 is provided downwardly from the center of the upper end plane 20. The bottom end of the mist outlet pipe 13 is sleeved in the mist outlet through-hole 21, and a liquid inlet 22 is downwardly provided on one side of the mist outlet through-hole 21. The bottom end of the atomizing seat 2 is upwardly recessed with a bottom cavity 23, and the mist outlet through-hole 21 is connected to the bottom cavity 23. The bottom cavity 23 is further upwardly provided with an atomizing core cavity 24, and the atomizing core cavity 24 is eccentrically arranged relative to the mist outlet through-hole 21. The atomizing core cavity 24 is connected to the liquid inlet 22, and the atomizing core 3 is sleeved upwardly in the atomizing core cavity 24 from the bottom cavity 23. Therefore, the atomizing core 3 is also eccentrically arranged relative to the mist outlet through-hole 21. An atomizing chamber 231 is provided between the atomizing seat 2 and the base 4 and below the atomizing core 3. A vertical air inlet hole 46 is provided on the atomizing seat 2. The air inlet hole 46 and the mist outlet hole 21 are arranged on the left and right sides of the atomizing core 3 opposite to each other. The atomizing chamber 231 is horizontally connected to the air inlet hole 46 and the mist outlet hole 21.

[0049] The atomizer with an offset atomizer core of the present invention, due to the aforementioned structural features and the structure of the offset atomizer core, has an airflow channel with two right-angle turns. That is, external air is introduced upward through the air inlet hole 46, then makes a right-angle turn laterally to enter the atomization chamber 231 at the bottom of the atomizer core 3, and then makes another right-angle turn upward to be discharged through the mist outlet pipe 13. While in the atomization chamber 231, the airflow can flow completely horizontally through the heating layer 33 at the bottom of the atomizer core 3. That is, the airflow passes through the entire heating area of ​​the heating layer 33, thereby entraining more aerosol or smoke and achieving more complete atomization, thereby improving atomization efficiency.

[0050] In other embodiments, the mist outlet hole 21 is not located at the exact center or near the exact center of the upper plane 20 , and liquid inlets are provided on two or more sides of the mist outlet hole 21 , and two or more atomizing core cavities 24 are also provided.

[0051] As shown in Figures 5 to 9, the atomizer of the present invention has an offset atomizing core. The outer wall of the atomizing seat 2 is provided with an annular ridge 25, and the inner wall of the mist outlet 21 is provided with an annular ridge 210. The annular ridges 25 and 210 both function as sealing rings.

[0052] The upper end plane 20 of the atomizer seat 2 is provided with an inclined surface 201, and the liquid inlet 22 is provided at the bottom end of the inclined surface 201. When the atomizer is in use, even if the amount of atomized liquid in the liquid storage chamber 15 is small, the atomized liquid can flow along the inclined surface 201 to the liquid inlet 22 to supply the atomizer core 3, so as to maximize the consumption and utilization of the atomized liquid.

[0053] A slot 29 is provided on the edge of the upper end plane of the atomizer seat 2 at a side located at a high position of the inclined surface 201. The slot 29 is used to clamp the axial rib 16 protruding inwardly on the inner wall of the shell. The bottom end of the axial rib 16 is clamped in the slot 29, which can enable the atomizer seat 2 to be axially and circumferentially positioned in the shell 1, and to be fixed to prevent loosening and deformation.

[0054] A right-angled step 241 is provided at the junction of the inner wall of the atomizer core chamber 24 and the inner wall of the liquid inlet 22. The upper edge of the atomizer core 3 abuts against the right-angled step 241. The right-angled step 241 prevents the atomizer core 3 from moving upward, ensuring more reliable operation of the atomizer core 3. It also ensures close contact between the upper edge of the atomizer core 3 and the right-angled step 241 for a seal, preventing the atomized liquid in the liquid storage chamber from leaking downward through the gap between the two.

[0055] A continuous ventilation groove 242 is formed on the inner walls of the atomizer core cavity 24, the right-angled step 241, and the liquid inlet 22. This serves to connect the bottom cavity 23 with the liquid inlet 22, thereby eliminating negative pressure within the liquid storage chamber 15. The ventilation groove 242 is a tiny groove, approximately 0.15mm-0.45mm in width and depth, which allows air to pass easily while providing some resistance to the liquid. When the atomized liquid in the liquid storage chamber 15 decreases after use, the internal pressure may become negative. In this case, the atomized liquid in the liquid storage chamber 15 is less likely to penetrate into the atomizer core 3, resulting in a lack of aerosol or smoke. With the addition of the ventilation groove 242, when negative pressure is generated within the liquid storage chamber 15, air within the atomizer chamber can pass through the gap between the sidewall of the atomizer core and the atomizer core chamber, then through the ventilation groove 242 to the liquid inlet 22, and then to the liquid storage chamber 15. This eliminates the negative pressure within the liquid storage chamber 15, allowing the atomized liquid to penetrate the atomizer core normally. When the pressure within the liquid storage chamber 15 is normal, the tension exerted by the tiny ventilation groove 242 prevents the atomized liquid from leaking back out of the liquid storage chamber 15.

[0056] The atomizer seat 2 of the present invention is integrally formed from a sealing material with a moderate hardness. Moderate hardness here refers to a hardness that is neither too soft nor too hard, but roughly medium. The sealing material can be a silicone material. This moderate hardness sealing material has a certain hardness to maintain a certain shape and not deform in high temperature environments such as 100-250°C. It also has a certain flexibility to ensure a tight seal when connected to other accessories, eliminating the need for a separate sealing material to ensure a tight connection. For example, the mist outlet through hole 21 of the present embodiment can be directly connected to the mist outlet pipe 13 without the need for additional sealing sleeves or sealing rings; the atomizer core 3 is arranged in the atomizer core cavity 24, and the two can be sealed because the integrated atomizer seat has a certain softness, and there is no need to add additional seals; the atomizer seat 2 is connected to the base 4 up and down, and the connection part between the two can also be sealed by itself without the need for additional seals; the outer wall of the atomizer seat 2 is provided with an annular ridge 25 so that the atomizer seat 2 acts as a sealing ring when the inner wall of the shell 1 is connected, thereby preventing the atomized liquid stored in the liquid storage cavity 15 from leaking through the gap between the two. The atomizer seat 2 of the present invention, due to its above-mentioned characteristics, reduces the accessories inside the atomizer. The overall atomizer only requires a shell, an atomizer seat, an atomizer core and a base. The structure is simple, which not only reduces production costs, but also facilitates automated assembly production during assembly production, greatly improving production efficiency.

[0057] As shown in Figures 2-3 and 10-12, the base 4 includes a bottom plate 41 and a surrounding wall 42. The surrounding wall 42 is sleeved on the inner wall of the bottom cavity 23. An atomizing chamber 231 is defined between the bottom of the atomizing seat 2 and the bottom plate 41. The atomizing chamber 231 includes at least a portion of the bottom cavity 23.

[0058] The bottom plate 41 is further provided with a fixing post 43 that is higher than the surrounding wall 42. The bottom of the atomizer seat 2 is provided with a fixing hole 26 at a position opposite the fixing post 43. The connection between the fixing post 43 and the fixing hole 26 enables the base 4 to better support and fix the atomizer seat 2, preventing the atomizer seat 2 from loosening or deformation.

[0059] The bottom plate 41 is provided with a boss 44 at the location below the atomizer core 3. The connection between the boss 44 and the bottom plate 41 is provided with a sloped step 441. The boss 44 and sloped step 441 are provided to prevent the atomized liquid at the bottom of the atomizer core 3 from being fully atomized. When small droplets of liquid dripping or condensing and falling onto the boss 44, waste atomized liquid is formed. Due to its higher elevation, the waste liquid can flow downward to the bottom plate 41 and further into the liquid collection chamber 48 described below.

[0060] An electrode through-hole 45 is formed on the boss 44 . A columnar electrode 5 is passed through the electrode through-hole 45 . The top end of the columnar electrode 5 abuts against two sides of the bottom of the atomizing core 3 .

[0061] An air inlet hole 46 is provided on the boss 44, outside the projected area below the atomizer core. A ledge 461 is provided between the air inlet hole 46 and the projected area below the atomizer core to prevent atomized liquid from dripping onto the boss 44 from flowing into the air inlet hole 46. There is also a space above the ledge 461 for air flow, allowing air entering through the air inlet hole 46 to flow into the atomization chamber 231 at the bottom of the atomizer core 3.

[0062] A baffle 47 having the same height as the surrounding wall 42 is provided upward from the bottom of the inclined step 441. The baffle 47 is located below the mist outlet hole 21 and is set in an arc shape to avoid blocking the mist outlet hole 21. A crack 470 is provided in the middle of the baffle 47. The baffle 47 is enclosed with the surrounding wall 42 on the other side of the boss 44 to form a liquid collecting chamber 48, and the liquid collecting chamber 48 is filled with an absorption liquid 6. The baffle 47 is used to enclose the liquid collecting chamber 48. The crack 470 of the baffle is used for the atomized liquid waste liquid flowing down from the boss 44 to pass through and flow into the liquid collecting chamber 48. The absorption liquid 6 is provided to absorb more atomized liquid waste liquid, thereby preventing the atomized liquid waste liquid from shaking on the bottom plate 41 and further leaking out from the suction port 10 or the air inlet hole 46.

[0063] The bottom cavity 23 is located above the absorbing liquid 6 and further includes a condensation chamber 27. A communication groove 28 is provided between the bottom of the mist outlet hole 21 and the condensation chamber 27. During use, a portion of the atomized aerosol or electronic cigarette smoke can enter the condensation chamber 27 through the communication groove 28 when flowing through the mist outlet hole 21. Due to the lower temperature of the inner wall of the condensation chamber 27, the oversaturated vapor in the mist or smoke can condense into small droplets on the inner wall of the condensation chamber 27. The small droplets further drip downward and are absorbed by the absorbing liquid 6.

[0064] The absorbing liquid 6 can be made of a material with good adsorption capacity, such as sponge, cotton, porous ceramic, or nickel foam. Furthermore, the absorbing liquid 6 can have good gas permeability, thereby absorbing small droplets or oversaturated water vapor carried by the gas as it passes through. At this point, a portion of the aerosol or smoke atomized in the atomization chamber 23 can simultaneously pass through the baffle slit 470 and enter the absorbing liquid 6 before being discharged through the communication groove 28. Any small droplets or oversaturated water vapor contained therein can then be absorbed by the absorbing liquid 6.

[0065] The working principle of the atomizer with an offset atomizer core in this embodiment is as follows: As shown in Figures 2-3, when the user inhales from the inhalation port 10, a negative pressure is generated inside the atomizer. As shown by the continuous arrow a in the figure, the external air enters the atomizing chamber 231 from the air inlet hole 46; as shown by the continuous arrow b in the figure, the atomized liquid in the liquid storage chamber 15 flows downward through the liquid inlet 22 to the upper surface of the atomizing core 3. The atomized liquid then further penetrates downward within the atomizing core 3 and diffuses to the heating layer 33 on its lower surface. After being heated by the heating layer 33, the atomized liquid is atomized into vapor or electronic cigarette smoke in the atomizing chamber 231. The generated vapor, driven by the air entering through the air inlet hole 46 at the bottom of the atomizing core 3, further flows horizontally to the mist outlet hole 21, then flows through the mist outlet pipe 13 to the inhalation port 10, and is finally inhaled into the mouth of the user. The vapor flow direction is as shown by the continuous arrow a in the figure. Industrial Applicability
