Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic atomizer technology, and more specifically, to an electronic atomizer with a direct airflow channel. Background Technology
[0002] Existing electronic cigarettes or electronic atomization devices generally include a power supply component and an electronic atomizer. The power supply component contains a battery that supplies power to the electronic atomizer. When powered on, the atomizing core inside the electronic atomizer heats and evaporates the solution to be atomized, i.e., the atomizing liquid or e-cigarette liquid, into vapor, electronic smoke, or aerosol. The atomizing liquid is stored in a reservoir inside the electronic atomizer.
[0003] In existing electronic atomizers on the market, the atomizing coil is generally placed horizontally on the atomizer base. The upper side of the atomizing coil faces the liquid reservoir to form the liquid inlet surface, and the lower side faces the atomization channel to form the atomization surface. The airflow entering from the bottom of the atomizer flows horizontally after entering the atomization channel. After the atomized liquid vaporizes on the atomization surface, it is released downwards as an aerosol or electronic vapor, which is then carried by the horizontally flowing airflow and flows upwards through the vapor outlet channel. This airflow channel is a curved airflow channel with a relatively slow airflow velocity. This results in the vapor being inhaled a longer distance to the user's mouth, causing greater flavor decay. The vapor inhaled by the user is not full enough and has a poor taste, resulting in a poor user experience. Utility Model Content

The descriptions of the various components of the electronic atomizer in this article, such as "upper, lower, upper part, lower part, bottom, upper end, lower end, bottom end, above, below, bottom surface, upward, downward, horizontal, vertical", all refer to the positional relationship of the components when the electronic atomizer is placed vertically with the inlet facing upwards.
[0031] Example
[0032] like Figure 1 , Figure 2As shown, the electronic atomizer with a straight air passage of this utility model includes an atomizer shell 1, an upper part of the atomizer shell 1, a suction port 10 at the top of the atomizer shell 1, an air inlet 11 extending downward into the interior of the atomizer shell 1 from the suction port 10, a liquid storage chamber 100 for storing atomized liquid in the upper inner part of the atomizer shell 1, and an atomizer bottom cover 7 fitted onto the bottom of the atomizer shell 1.
[0033] like Figures 2-5 As shown, the inner wall of the atomizer shell 1 is connected to the atomizing component 8 at the upper part of the atomizer bottom cover 7 and the lower part of the liquid storage chamber 100. The atomizing component 8 includes an atomizing bracket 2, an atomizing core 3 and an atomizing base 4.
[0034] like Figures 6-8 As shown, the upper part of the atomizing bracket 2 is provided with a mist outlet hole 20 that is sleeved with the inhalation pipe 11. The lower part of the atomizing bracket 2 has a structure that is cut off in half along the vertical central axis to form a bracket half 201. The atomizing core 3 is vertically and laterally arranged on the bracket half 201. "Vertically and laterally" means that the atomizing surface of the atomizing core 3 is vertically and laterally arranged on one side of the atomizing channel.
[0035] like Figures 9-11 As shown, the bottom of the atomizing base 4 is provided with an air inlet 40, and the upper part of the atomizing base 4 has a structure that is cut off in half along the vertical central axis to form a base half 401.
[0036] like Figures 2-11 As shown, the atomizing bracket 2 and the atomizing base 4 are connected vertically, and the bracket half 201 and the base half 401 are laterally connected to form a whole. In this embodiment, the bracket half 201 and the base half 401 are fastened together by a side-mounted snap-fit connection structure, wherein the bracket half 201 has slots 211 on both sides, and the base half 401 has hooks 411 on both sides, and the hooks 411 are fastened together in the slots 211.
[0037] A cavity forming an atomizing channel 300 is provided between the support half 201 and the base half 401. The atomizing channel 300 is connected to the air inlet 40 and the air intake pipe 11. The atomizing channel 300 and the air intake pipe 11 are connected in a straight line from bottom to top to form a straight air passage.
[0038] The outer wall of the base half 201 is provided with a concave part 202. The concave part 202 and the inner wall of the atomizer shell 1 form a liquid inlet channel 200, which is connected to the liquid storage chamber 100.
[0039] like Figures 6-8As shown, the atomizing bracket 2 is composed of a bracket body 21 and a bracket sealing cap 22. The bracket sealing cap 22 is sleeved on the bracket body 21 and is used to seal the gap between the bracket body 21 and the inner wall of the atomizer shell 1, as well as between the mist outlet hole 20 and the air inlet pipe 11, to ensure that the atomized liquid in the liquid storage chamber 100 does not leak except when it enters the liquid inlet channel 200.
[0040] The bracket half 201 of the atomizing bracket is provided with an opening 203 that connects the liquid inlet channel 200 and the atomizing channel 300. The atomizing core 3 includes a liquid inlet surface 3A and an atomizing surface 3B facing away from the liquid inlet surface. The atomizing core 3 is sealed in the opening 203. The liquid inlet surface 3A of the atomizing core 3 is vertically arranged on the side of the liquid inlet channel 200, and the atomizing surface 3B of the atomizing core 3 is vertically arranged laterally on the side of the atomizing channel 300. The atomizing surface 3B of the atomizing core 3 is parallel to the airflow direction in the atomizing channel 300.
[0041] In this invention, the bracket half 201 and the base half 401 are laterally connected to form an integral structure, so that the atomizing core 3 can be assembled on the bracket half 201 of the atomizing bracket first, and then the bracket half 201 and the base half 401 are fastened together, making the assembly process in production simple and efficient, which helps to save costs and increase production.
[0042] This invention relates to an electronic atomizer with a direct airflow channel. When the user inhales, a negative pressure is generated inside the atomizer, triggering the atomizing core 3 to operate. External air enters the atomization channel 300 through the air inlet 40, and then, together with the electronic vapor generated by the atomizing core 3, flows vertically upward through the vapor outlet 20, the inhalation tube 11, and the inhalation port 10, and is drawn into the user's mouth. The airflow and the direction of the electronic vapor flow generated by this invention's electronic atomizer with a direct airflow channel are as follows: Figure 3 As shown by the continuous arrows in the image.
[0043] When the atomizing core 3 is powered on, the atomizing liquid in the liquid storage chamber 100 flows downward through the liquid inlet channel 200 and seeps into the atomizing core 3 from the liquid inlet surface 3A. It then seeps out from the atomizing surface 3B and is heated and vaporized by the heating layer 32, generating aerosol or electronic smoke. In other words, the atomizing liquid is atomized laterally and dispersed into the atomizing channel 300. It is then carried by the airflow parallel to the atomizing surface 3B and discharged through the suction pipe 11. In this structure, when the user inhales, the aerosol or e-cigarette vapor generated by the atomizing core 3 is dispersed into the atomization channel 300. At the same time, outside air enters the atomization channel 300 through the air inlet 40, generating airflow. The airflow flows upward in a straight line parallel to the atomizing surface 3B within the atomization channel 300, and is discharged through the inhalation tube 11 and the mouthpiece 10, generating a strong airflow that directly washes the atomizing surface 3B. This airflow can carry out larger molecules of atomized substances such as sweeteners generated by the atomizing surface 3B, allowing them to be inhaled into the user's mouth simultaneously with the airflow. Furthermore, the atomizing core 3 is vertically and laterally positioned at the opening 203 of the atomization channel 300. The atomization channel 300 and the inhalation tube 11 are connected in a straight line from bottom to top, forming a straight airway. The e-cigarette vapor generated by the atomizing core 3 does not need to bend and can be directly inhaled by the user, shortening the distance the vapor travels to the user's mouth, reducing flavor decay, and greatly improving the flavor reproduction of the vapor. This allows the user to obtain a fuller vapor and taste, providing a better user experience.
[0044] like Figures 9-11 As shown, the atomizing base 4 includes a base body 41, an inner sealing sleeve 42, and an outer sealing ring 43. The inner sealing sleeve 42 is fitted onto the inner wall of the base body 41 to seal the connection gap between the base body 41 and the support body 21. The outer sealing ring 43 is fitted onto the lower outer wall of the base body 41 to seal the gap between the base body 41 and the inner wall of the atomizer shell 1.
[0045] The inner sealing sleeve 42 of the base is located below the atomizing channel 300 and above the air inlet 40, and has an inclined surface 421. The lower inner part of the base body 41 has a liquid collection groove 412. The liquid droplets condensed on the inner wall of the atomizing channel 300 become residual liquid and drip onto the inclined surface 41, and can then drip further along the inclined surface 41 into the liquid collection groove 412, preventing residual liquid from leaking outward from the air inlet 40. The liquid collection groove 412 is equipped with absorbent cotton 5, which can better absorb the solidified residual liquid and prevent residual liquid from flowing.
[0046] like Figure 12 , Figure 13 As shown, the atomizing core 3 includes a porous liquid guiding layer 31 and a heating layer 32. The heating layer 32 is applied to the atomizing surface 3B of the porous liquid guiding layer 31, and electrode layers 33 are also connected to the left and right sides of the heating layer 32.
[0047] like Figures 2-5As shown, the atomizing core 3 also includes a liquid permeation sheet 30 that is closely attached to the porous liquid guide 31 on the side opposite to the heating layer, i.e., the liquid inlet surface 3A. The porous liquid guide 31 is made of porous ceramic material through sintering.
[0048] An electrode post 6 is vertically provided on the base plate of the atomizing base 41, and the side of the electrode post 6 is in contact with the electrode layer 33.
[0049] 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.
