[0002] This application claims priority to Chinese patent application filed on December 27, 2024, with application number 202423275180.2 and entitled “Atomizer and Electronic Atomizing Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of atomization technology, and in particular to an atomizer and an electronic atomization device. Background Technology

[0004] Aerosols are colloidal dispersion systems formed by solid or liquid particles dispersed and suspended in a gaseous medium. Aerosols can be absorbed by the human body through the respiratory system, providing users with a novel alternative absorption method. Atomizing devices are devices that generate aerosols from stored atomizing media through heating or ultrasound. Atomizing media include liquid, gel, paste, or solid aerosol-generating matrices. Atomizing these media delivers inhalable aerosols to users, replacing conventional product forms and absorption methods.

[0005] Atomizing devices typically consist of a liquid reservoir and an atomizing core located on one side of the reservoir. The reservoir stores the atomizing medium and supplies it to the atomizing core. The atomizing core absorbs the medium and heats it with electrical energy to generate an aerosol. However, due to structural limitations, existing atomizing devices have a limited size for the liquid inlet channel connecting the reservoir and the atomizing core. This can easily lead to immobile air bubbles during inverted-upright use, causing the atomizing core to dry-burn due to insufficient liquid supply, resulting in a burnt taste and affecting the flavor.

[0042] Referring to Figure 1, an embodiment of this application provides an electronic atomizing device 1000 for heating an atomizing medium to generate an aerosol for user use. The atomizing medium includes, but is not limited to, liquid materials such as medicines and oils used for medical, health, and beauty purposes.

[0043] The electronic atomizing device 1000 includes an atomizer 100 and a battery assembly 300. The battery assembly 300 is connected to one end of the atomizer 100 and electrically connected to the atomizer 100. The atomizer 100 is used to store the atomizing medium and, under the action of the electrical energy of the battery assembly 300, heats and atomizes the atomizing medium to generate an aerosol for the user to use.

[0044] In the following embodiments, the height direction of the electronic atomizing device 1000 is defined as the first direction (i.e., the Z direction in Figure 1), the length direction of the electronic atomizing device 1000 is defined as the second direction (i.e., the X direction in Figure 1), and the width direction of the electronic atomizing device 1000 is defined as the third direction (i.e., the Y direction in Figure 1). The atomizer 100 and the battery assembly 300 are connected to each other in the first direction. Wherein, the first direction, the second direction, and the third direction intersect each other; in a preferred embodiment, the first direction, the second direction, and the third direction are perpendicular to each other.

[0045] As shown in Figures 2 to 5, the atomizer 100 includes a main housing 110, an atomizing base 120, and an atomizing core 130. Specifically, the main housing 110 has a hollow shell structure with one open end, including an open end and a closed end disposed opposite to each other in a first direction. An air outlet channel 110a and a liquid storage chamber 110b are provided in the end of the main housing 110 near the closed end. One end of the air outlet channel 110a penetrates the closed end of the main housing 110 to connect with the external atmosphere, and the other end of the air outlet channel 110a extends towards the open end of the main housing 110 along the first direction. The liquid storage chamber 110b surrounds the air outlet channel 110a circumferentially and is used to store the atomizing medium. The air outlet channel 110a allows the aerosol generated by atomization to flow out.

[0046] The atomizing seat 120 is installed in one end of the main housing 110 near the opening end and is located on one side of the liquid storage chamber 110b in the first direction. The atomizing seat 120 is configured to form a liquid inlet channel 120a, which extends along the first direction and communicates with the liquid storage chamber 110b.

[0047] The atomizing core 130 is disposed within the atomizing base 120 and located on one side of the liquid inlet channel 120a in the second direction. The atomizing core 130 has a liquid inlet surface 130a facing the liquid inlet channel 120a and an atomizing surface 130b facing away from the liquid inlet channel 120a. The liquid inlet surface 130a is used to absorb the atomizing medium, and the atomizing surface 130b is used to heat the atomizing medium. An airflow channel 120b is formed between the atomizing surface 130b and the atomizing base 120. The airflow channel 120b extends in the first direction to connect the atomizing surface 130b with the external atmosphere.

[0048] In one specific embodiment, the atomizing core 130 has a cubic structure. The length direction of the atomizing core 130 is parallel to a third direction, the width direction is parallel to a second direction, and the height direction is parallel to a first direction. The atomizing core 130 is a porous structure formed of high-temperature resistant materials such as ceramics. A heating element formed of materials such as metal wires or metal mesh is embedded on the side of the atomizing core 130 facing away from the liquid inlet channel 120a. The heating element is electrically connected to the battery assembly 300, thereby heating the atomizing medium to generate an aerosol.

[0049] Thus, the atomizing medium in the storage chamber 110b reaches the inlet surface 130a of the atomizing core 130 through the inlet channel 120a, and is then guided to the atomizing surface 130b and heated by the atomizing surface 130b to generate aerosol. The aerosol generated by atomization flows sequentially through the airflow channel 120b and the outlet channel 110a into the external atmosphere. Compared with the downward and upward atomization methods in the prior art, the lateral atomization method in this application has a shorter aerosol transport path, can carry out more aerosol, and improves the utilization rate of the atomizing medium.

[0050] As described in the background section, in lateral atomizing atomizers, the inlet channel is relatively narrow, making it easy for air bubbles to get stuck, leading to problems such as poor liquid intake and insufficient liquid supply to the atomizing core. Specifically, in this application, in the first direction, the length of the inlet channel 120a is greater than the length of the inlet surface 130a, thus meeting the structural design requirements for lateral atomization without requiring a large space. However, because the inlet channel 120a is relatively long and narrow, air bubbles accumulate in it, resulting in insufficient liquid supply to the atomizing core 130.

[0051] Based on the above-mentioned technical problems, in this application, at least one protruding post 140 is provided inside the liquid inlet channel 120a, thereby increasing the roughness of the channel wall of the liquid inlet channel 120a, thereby increasing the wettability of the liquid inlet channel 120a. The contact angle between the air bubbles in the liquid inlet channel 120a and the channel wall becomes larger, so the air bubbles are more likely to detach from the channel wall and be discharged from the liquid inlet channel 120a. Ultimately, it can prevent the atomizing core 130 from dry burning and producing a burnt smell due to insufficient liquid supply caused by the presence of air bubbles.

[0052] Figures 3 to 7 show an atomizer 100 provided in the first embodiment of this application.

[0053] Referring to Figures 3 to 5, in the first embodiment, the atomizing base 120 has a liquid inlet channel 120a on one side in the second direction. The liquid inlet channel 120a has a bottom wall and a side wall. The side wall extends from the edge of the bottom wall in the first direction and surrounds the bottom wall circumferentially. A liquid inlet 121a communicating with the liquid inlet surface 130a is provided on the side of the side wall near the atomizing core 130. Thus, the atomizing medium in the liquid storage chamber 110b flows into the liquid inlet channel 120a in the first direction, and then flows into the atomizing core 130 through the liquid inlet 121a in the second direction.

[0054] The protruding post 140 protrudes from the bottom wall of the channel and connects to the side of the channel side wall away from the atomizing core 130, thereby effectively improving the wettability of the bottom wall of the channel. The contact angle between the air bubbles in the liquid inlet channel 120a and the side wall and bottom wall of the channel becomes larger, so the air bubbles are more likely to detach from the side wall and bottom wall of the channel and be discharged from the liquid inlet channel 120a. Ultimately, it can prevent the atomizing core 130 from dry burning and producing a burnt smell due to insufficient liquid supply caused by the presence of air bubbles.

[0055] In one specific embodiment, the length h of the liquid inlet channel 120a in the first direction is greater than 6 mm, the width of the liquid inlet channel 120a in the second direction is less than 2 mm, and the length of the liquid inlet channel 120a in the third direction is less than 4.6 mm. Referring to Figures 6 and 7, the liquid inlet channel 120a is provided with multiple protrusions 140, all of which are arranged at intervals along the third direction. Each protrusion 140 is approximately a long strip extending along the first direction. The distance l between two adjacent protrusions 140 is 0.7 mm, the height h of each protrusion 140 in the first direction is 2.3 mm, the length a of each protrusion 140 in the second direction is 1.67 mm, and the width b of each protrusion 140 in the third direction is 0.4 mm.

[0056] It is understood that the dimensions of the liquid inlet channel 120a, the shape, size, and number of the protrusions 140 are not limited to these, and can be set as needed to meet different liquid inlet requirements.

[0057] Further, referring again to Figure 3, a guide groove 120c is provided on the side of the channel sidewall away from the atomizing core 130. The guide groove 120c extends from one end of the liquid inlet channel 120a to the other end of the liquid inlet channel 120a along a first direction. When the electronic atomizing device 1000 is in the upright state, the liquid can be guided by the capillary action formed by the guide groove 120c. When the electronic atomizing device 1000 is in the inverted state during use, the guide groove 120c can effectively lock the atomizing medium, preventing excessive flow of the atomizing medium and the generation of bubbles. As a preferred embodiment, multiple guide grooves 120c are provided on the channel sidewall, and all guide grooves 120c are arranged at intervals along a third direction. It is understood that the shape, length, number, and arrangement of the guide grooves 120c are not limited, and can be set as needed to meet different flow guidance and liquid locking requirements.

[0058] Figures 8 to 10 show an atomizer 100 provided in the second embodiment of this application.

[0059] In the second embodiment, the liquid inlet channel 120a is formed between the atomizing seat 120 and the main housing 110. The atomizing seat 120 has a liquid inlet 121a that connects the liquid inlet channel 120a and the liquid inlet surface 130a. The protruding post 140 protrudes from the atomizing seat 120 and passes through the liquid inlet 121a in the first direction.

[0060] Specifically, the side wall of the atomizing base 120 facing away from the atomizing core 130 in the second direction is recessed inward, thus forming a liquid inlet channel 120a together with the inner side wall of the main housing 110. The liquid inlet channel 120a includes a first liquid inlet section and two second liquid inlet sections. The two second liquid inlet sections are located on opposite sides of the first liquid inlet section in the third direction. The end of the second liquid inlet section near the liquid storage chamber 110b is connected to the liquid storage chamber 110b, and the other end of the second liquid inlet section away from the liquid storage chamber 110b is connected to the first liquid inlet section. The liquid inlet 121a is opened in the first liquid inlet section, so the atomizing medium in the liquid storage chamber 110b enters the atomizing core 130 in sequence through the second liquid inlet section, the first liquid inlet section, and the liquid inlet 121a.

[0061] Furthermore, the side wall of the atomizing seat 120 facing away from the atomizing core 130 in the second direction includes a first wall surface 121 and two second walls surface 123. The two second walls surface 123 are located on opposite sides of the first wall surface 121 in the third direction. The distance between the second walls surface 123 and the inner wall of the main housing 110 on the other side of the liquid inlet channel 120a is greater than the distance between the first walls surface 121 and the inner wall of the main housing 110 on the other side of the liquid inlet channel 120a. Therefore, a first liquid inlet section is formed between the first walls surface 121 and the main housing 110, and a second liquid inlet section is formed between the second walls surface 123 and the main housing 110. The liquid inlet 121a is opened on the side of the first walls surface 121 away from the liquid storage chamber 110b.

[0062] In order to guide the atomizing medium, the first wall surface 121 is provided with a liquid inlet groove 121b. Multiple liquid inlet grooves 121b are located on opposite sides of the liquid inlet 121a in the third direction. All liquid inlet grooves 121b located on the same side of the liquid inlet 121a in the third direction are arranged at intervals along the first direction. Each liquid inlet groove 121b extends along the third direction to connect the second liquid inlet section and the liquid inlet 121a.

[0063] Multiple protrusions 140 are provided on the first wall surface 121, and all protrusions 140 are spaced apart along a third direction. Each protrusion 140 extends along a first direction to pass through the liquid inlet 121a, so that the atomizing medium enters the atomizing core 130 from the gap between two adjacent protrusions 140. In some embodiments, each protrusion 140 has multiple drainage grooves 140a on opposite sides in a second direction, and all drainage grooves 140a are spaced apart along the first direction. Each drainage groove 140a extends along a third direction.

[0064] Thus, the atomizing medium in the storage chamber 110b enters the two second inlet sections respectively, and then flows along the inlet groove 121b of the first inlet section toward the inlet port 121a. Finally, guided by the guide groove 140a, it passes through the gap between two adjacent protrusions 140 and enters the inlet port 121a, and finally reaches the atomizing core 130.

[0065] It is understandable that the shape, number, and arrangement of the liquid inlet tank 121b and the diversion tank 140a are not limited, so as to meet different liquid guiding requirements.

[0066] The aforementioned atomizer 100 and electronic atomizing device 1000, through the arrangement of structures such as the protruding post 140, can effectively increase the wettability of the channel wall of the liquid inlet channel 120a, thereby facilitating the detachment of bubbles generated during the liquid inlet process from the channel wall, thus preventing problems of poor liquid inlet and insufficient liquid supply caused by bubbles, and improving the taste of the aerosol generated by atomization.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
