Description

Technical Field

[0001] This utility model relates to the field of atomizer technology, and more specifically, to an atomizer having a semi-circular tubular atomizing core. Background Technology

[0002] Existing electronic cigarettes or electronic atomization devices generally include a power supply component and an atomizer. The power supply component contains a battery that supplies power to the atomizer. When powered on, the atomizing core in the atomizer heats and evaporates the solution to be atomized, i.e., the atomizing liquid or e-cigarette liquid, into vapor, e-cigarette smoke, or aerosol. The atomizing liquid is stored in a reservoir inside the atomizer.

[0003] Currently, atomizers with porous atomizing coils on the market generally have a flat atomizing surface. Due to the limited atomization space inside the atomizer, the size of the atomizing coil is generally made relatively small. Therefore, the area of ​​the flat atomizing surface is limited by the small size of the atomizing coil, resulting in a smaller atomization volume and lower atomization efficiency.

[0004] In existing atomizers with porous atomizing coils, the coil is typically placed horizontally on the atomizer base. The upper side of the coil faces the liquid reservoir, forming the liquid inlet surface, while the lower side faces the atomization chamber, forming the atomization surface. The airflow entering from the bottom of the atomizer flows laterally into the atomization chamber. The atomized liquid vaporizes on the atomization surface and disperses downwards as aerosol or e-cigarette vapor, which is then carried by the laterally flowing airflow and flows upwards through the vapor outlet channel. This airflow channel is a winding and turning channel with a relatively slow airflow velocity. This results in a longer distance for the vapor to reach the user's mouth, greater flavor attenuation, and a less full and less flavorful vapor, leading to a poor user experience. Utility Model Content

[0005] This invention provides an atomizer with a semi-circular tubular atomizing core to overcome the above-mentioned technical deficiencies.

[0006] The technical solution of this utility model is implemented as follows: An atomizer with a semi-circular tubular atomizing core includes a mouthpiece shell. The top of the mouthpiece shell is provided with a suction port. An air inlet tube extends downward from the suction port into the mouthpiece shell. A liquid storage chamber for storing atomizing liquid is provided in the upper inner part of the mouthpiece shell. A sealing cap and an atomizing base are fitted onto the inner wall of the mouthpiece shell below the liquid storage chamber. The sealing cap is placed on the atomizing base. A base cavity is provided on the atomizing base. A tubular support is provided at the bottom of the base cavity. A notch is provided on the wall of the tubular support. The notch is filled with a semi-circular tubular atomizing core. A fixing sleeve is fitted onto the outer wall of the tubular support. A liquid inlet hole is provided on the wall of the fixing sleeve at the atomizing core. The liquid inlet hole is located above the sealing cap and directly connects to the liquid storage chamber. The upper end of the fixing sleeve is fitted onto the bottom end of the air inlet tube.

[0007] Preferably, the atomizing core includes a semi-circular tubular liquid guide and a heating layer and an electrode layer disposed on the surface of the liquid guide. The arc-shaped concave surface of the liquid guide is designated as the atomizing surface, and its arc-shaped convex surface is designated as the liquid inlet surface. The heating layer is disposed on the atomizing surface, and the electrode layer is disposed on the surfaces of both ends of the semi-circular tubular tube wall of the liquid guide and is electrically connected to the heating layer.

[0008] Preferably, the liquid guiding material is a porous ceramic body made of ceramic material and having an overall microporous structure.

[0009] Preferably, the heating layer is a metal coating layer deposited on the atomizing surface, and the metal coating layer includes micropores to allow the aerosol after heating and evaporation to penetrate and dissipate.

[0010] Preferably, an electrode column is vertically disposed inside the tubular support, and the electrode layer is in contact with the side wall of the electrode column.

[0011] Preferably, the tubular support has two symmetrical notches on its tube wall, and the atomizing core also has two notches corresponding to each of the two notches.

[0012] Preferably, a ring of fluid-guiding cotton is provided between the tubular support and the fixing sleeve.

[0013] Preferably, a fixing plate is also connected to the upper part of the sealing cover, and the upper surface of the fixing plate is provided with an inclined surface that slopes toward the liquid inlet hole.

[0014] Preferably, it also includes an atomizer bottom shell fitted onto the lower end of the mouthpiece shell.

[0015] Preferably, an air intake chamber is provided between the sealing cap and the atomizing base, a first air intake hole is provided at the bottom of the atomizing base, and a second air intake hole is provided at the bottom of the tubular support. The first air intake hole communicates with the second air intake hole through the air intake chamber.

[0016] The beneficial effects of this atomizer with a semi-circular tubular atomizing core are as follows: The atomizer of this invention features a semi-circular tubular atomizing core with an arc-shaped concave surface for its atomizing surface. This allows the atomizing core to have a larger atomizing surface area for the same external dimensions, significantly improving the atomization volume and efficiency. Simultaneously, the arc-shaped convex surface forming the liquid inlet surface further enhances the liquid inlet area for the same external dimensions, allowing for a larger amount of atomizing liquid to enter and more timely liquid supply, which also greatly improves the atomization volume and efficiency. Furthermore, the atomizing core of this invention is installed within the notch of the tubular support. Its arc-shaped concave atomizing surface can directly form the vertical wall of the vertically connected atomizing channel. This allows the aerosol or smoke-like vapor evaporated from the atomizing surface to be directly swept and carried out by the upward airflow. The generated smoke does not need to turn and can be directly inhaled by the user, shortening the distance the smoke travels to the user's mouth and allowing it to be inhaled more quickly. This reduces flavor decay, improves the flavor reproduction of the smoke, and allows the user to obtain a fuller smoke and taste, thus enhancing the user experience. Attached Figure Description

[0026] This utility model relates to an atomizer with a semi-circular tubular atomizing core. For ease of description, as follows: Figure 4 , Figure 5 As shown, the atomizer of this utility model is placed vertically with the inlet 10 facing upwards. Any descriptions of the atomizer components such as "upper, lower, upper part, lower part, bottom, upper end, lower end, bottom end, above, below, bottom surface, upward, downward, horizontal, vertical" in this article refer to the positional relationship of the components when the atomizer is placed vertically with the inlet facing upwards.

[0027] Example

[0028] like Figures 1-8 As shown, this utility model has an atomizer with a semi-circular tubular atomizing core, including a mouthpiece shell 1. The upper part of the mouthpiece shell 1 is tapered into the shape of a mouthpiece. The top of the mouthpiece shell 1 is provided with a suction port 10. The suction port 10 extends downward into the mouthpiece shell 1 and is provided with an air inlet tube 11. The upper inner part of the mouthpiece shell 1 is provided with a liquid storage chamber 100 for storing atomized liquid. The inner wall of the mouthpiece shell 1 is fitted with a fixing plate 2, a sealing cap 3 and an atomizing base 4 below the liquid storage chamber 100. The sealing cap 3 is placed on the atomizing base 4. The lower end of the mouthpiece shell 1 is also fitted with an atomizer bottom shell 5. The atomizer bottom shell 5 can be made of stainless steel sheet material. The atomizer bottom shell 5 can support the atomizing base 4 and has a better aesthetic effect.

[0029] The atomizing base 4 has a base cavity 40, and a tubular support 41 protrudes upward from the bottom of the base cavity 40. A notch 410 is provided on the wall of the tubular support 41, and the notch 410 is filled with an atomizing core 6. The atomizing core 6 is approximately semi-circular in shape. A fixing sleeve 7 is fitted onto the outer wall of the tubular support 41, which fixes the atomizing core 6 within the notch 410 of the tubular support. A liquid inlet hole 70 is provided on the wall of the fixing sleeve 7 at the atomizing core. The liquid inlet hole 70 is located above the sealing cap 3 and extends directly into the liquid storage chamber 100. The upper end of the fixing sleeve 7 is fitted onto the bottom end of the suction pipe 11, and a sealing sleeve 71 is provided between the two to prevent leakage of the atomizing liquid from the liquid storage chamber 100.

[0030] The atomizing core 6 includes a generally semi-circular tubular liquid guide 61, a heating layer 62, and an electrode layer 63 disposed on the surface of the liquid guide 61. The arc-shaped concave surface of the liquid guide 61 is designated as the atomizing surface 612, and its arc-shaped convex surface is designated as the liquid inlet surface 611. The heating layer 62 is applied to the atomizing surface 612. Two electrode layers 63 are provided, respectively disposed on the surfaces of both ends of the semi-circular tubular wall of the liquid guide 61 and electrically connected to the heating layer 62. The atomizing surface 612 of the atomizing core 6 of this invention is an arc-shaped concave surface, which allows the atomizing core 6 to have a larger atomizing surface area with the same external dimensions, greatly improving the atomization volume and efficiency. Simultaneously, the arc-shaped convex surface forming the liquid inlet surface 11 allows the atomizing core 6 to have a larger liquid inlet surface area with the same external dimensions, resulting in a larger amount of atomizing liquid entering the liquid guide 1 and timely liquid supply, which also greatly improves the atomization volume and efficiency. In addition, the atomizing core 6 of this utility model is installed in the notch 410 of the tubular bracket 41. Its arc-shaped concave atomizing surface can directly form the vertical wall of the vertically connected atomizing channel, so that the aerosol or smoke-like vapor evaporated on the atomizing surface can be directly swept and carried out by the upward airflow. The generated smoke does not need to turn and can be directly inhaled by the user, shortening the distance that the smoke is delivered to the user's mouth and being inhaled by the user more quickly. This reduces flavor decay, improves the flavor reproduction of the smoke, and allows the user to obtain a fuller smoke and taste, thus improving the user experience.

[0031] In this invention, the tubular support 41 has a central cavity that connects vertically with the cavity inside the intake pipe 11 to form a straight atomization channel. The atomization surface 612 formed by the concave surface of the atomizing core 6 is vertically oriented towards the cavity, like the pipe wall. The portion of the cavity where the atomizing surface 612 of the atomizing core 6 is located constitutes the atomization chamber 600, which is part of the aforementioned atomization channel. When the atomizing core 6 is powered on, the atomizing liquid in the conductive liquid 61 is heated and evaporated by the heating layer 62, and the resulting aerosol or vaporous smoke can be emitted from the atomizing surface 612 into the atomization chamber 600.

[0032] The liquid guide 61 is a porous ceramic body made of ceramic material and has an overall microporous structure.

[0033] The heating layer 62 is a metal coating layer applied to the atomizing surface by a coating process. The metal coating layer includes micropores so that the aerosol after heating and evaporation can penetrate and dissipate. The metal coating layer has a certain resistance and can generate heat when electricity is applied to its two ends.

[0034] Two electrode posts 42 are vertically arranged inside the tubular support 41. The two electrode layers 63 of the atomizing core 6 are respectively connected to the side walls of the two electrode posts 42. The electrode posts 42 include a positive electrode post and a negative electrode post.

[0035] In this embodiment, two notches 410 are symmetrically provided on the wall of the tubular support 41, and two semi-circular atomizing cores 6 are also provided and correspondingly disposed in the two notches 410. The electrode layers of the two atomizing cores are respectively in contact with and connected to the two electrode posts 42. In this embodiment, the two atomizing cores 6 can be powered on and work simultaneously, which doubles the amount of atomization per unit time of the atomizer, thus improving the atomization effect.

[0036] A ring of liquid-guiding cotton 8 is also provided between the tubular support 41 and the fixed sleeve 7. The liquid-guiding cotton 8 can absorb and conduct the atomizing liquid. The liquid-guiding cotton 8 can buffer the atomizing liquid that passes through the liquid inlet hole 70 and enters the liquid guide 61. It has a certain blocking and slow-release effect, preventing the atomizing liquid from flowing too fast into the liquid guide and causing leakage, and preventing dry burning caused by the inability to supply liquid in time due to shaking when there is less atomizing liquid in the liquid storage chamber.

[0037] In this embodiment, the sealing cap 3 is made of silicone material and can seal the lower part of the liquid storage chamber to prevent leakage of the atomizing liquid. A fixing plate 2 is also connected to the upper part of the sealing cap 3. The fixing plate 2 can shape and support the sealing cap 3 downwards to prevent the sealing cap from softening and deforming at high temperatures, which would further lead to poor sealing and leakage. The upper surface of the fixing plate 2 is provided with an inclined surface that slopes towards the liquid inlet hole 70. This inclined surface allows the atomizing liquid in the liquid storage chamber 100 to flow smoothly to the liquid inlet hole 70 even when the amount of atomizing liquid is small, so as to maximize the consumption and utilization of the atomizing liquid.

[0038] An air inlet chamber 400 is provided between the sealing cap 3 and the atomizing base 4. The bottom of the atomizing base 4 is provided with a first air inlet hole 43, and the bottom of the tubular support 41 is provided with a second air inlet hole 411. The first air inlet hole 43 is connected to the second air inlet hole 411 through the air inlet chamber 400.

[0039] The atomizer base shell 5 has through holes at the positions of the electrode post 42 and the first vent 43 located on the atomizer base so as to expose the electrode post 42 and the first vent 43.

[0040] When the atomizer of this utility model is working, the user inhales through the inhalation port 10, which creates a negative pressure in the atomization channel of the atomizer. Outside air can then flow into the bottom of the tubular support 41 through the first air inlet 43, the air inlet chamber 400 and the second air inlet 411, and further enter the atomization channel upwards.

[0041] In this embodiment, the base cavity 40 of the atomizing base 4 is also provided with absorbent cotton 9. The absorbent cotton 9 is connected to the air inlet cavity 400 provided between the sealing cover 3 and the atomizing base 4. It can be used to absorb and store the condensate or waste liquid formed by the atomizing liquid that drips into the air inlet cavity 400 from the atomizing cavity or atomizing channel, and further prevent the condensate or waste liquid from leaking or being sucked into the user's mouth by the airflow.

[0042] In this embodiment, the fixing plate 2, the sealing cap 3, and the atomizing base 4 are each provided with a vertically penetrating injection hole, which connects to the liquid storage chamber 100. After the nozzle shell 1, the fixing plate 2, the sealing cap 3, and the atomizing base 4 are installed, atomizing liquid can be added to the liquid storage chamber 100 through the injection hole. Correspondingly, a plunger 44 is also provided from the bottom of the atomizing base 4. After the liquid storage chamber 100 is filled with atomizing liquid, the plunger 44 extends upward from the bottom of the atomizing base 4 into the aforementioned injection hole to prevent leakage of atomizing liquid.

[0043] When the atomizer of this invention is working, the user inhales through the inhalation port 10, creating a negative pressure in the atomization channel of the atomizer. This negative pressure is conducted to the power supply component connected to the atomizer, generating airflow within the power supply component and triggering the airflow sensor. The airflow sensor then turns on the power switch, energizing the atomizing core 6. When the atomizing core 6 is energized, the atomizing liquid in the liquid storage chamber 100 passes through the liquid inlet hole 70 and the liquid guide cotton 8, seeping into the atomizing core 6 from the liquid inlet surface 611. It then seeps out from the atomization surface 612 and is heated and vaporized by the heating layer 62, producing an aerosol or vapor-like smoke. In other words, the atomizing liquid is atomized laterally and dispersed into the atomization chamber 600, and then carried upward by the airflow entering through the second air inlet hole 411 and discharged through the inhalation port 10.

[0044] The above description is merely a preferred embodiment of the present utility model, and the specific embodiments described above are not intended to limit the present utility model. Various modifications and variations can be made within the scope of the technical concept of the present utility model. All refinements, modifications, or equivalent substitutions made by those skilled in the art based on the above description are within the scope of protection of the present utility model.
