Description

Technical Field

[0001] This application belongs to the field of atomization technology, and more specifically, relates to an electronic atomization device. Background Technology

[0002] Electronic atomizing devices generally include a housing, a mouthpiece, an atomizing coil, and an electronic control unit. The housing forms an interconnected media chamber and an atomizing chamber. The media chamber stores the atomizing medium, and the atomizing coil is located within the atomizing chamber. The electronic control unit supplies power to the atomizing coil when the user inhales through the mouthpiece. When powered, the atomizing coil atomizes the atomizing medium flowing from the media chamber for the user to inhale. Because the atomizing medium needs to flow from the media chamber to the atomizing chamber, if the supply of liquid in the media chamber is insufficient, it will cause the atomizing coil to burn out, which will damage the atomizing coil and is also harmful to the human body. Summary of the Invention

[0003] The purpose of this application is to provide an electronic atomizing device to solve the technical problem in the prior art that the atomizing core will dry-burn when the liquid supply from the medium chamber is not timely.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: An electronic atomizing device is provided, comprising an inner shell and an outer shell. The outer shell is fitted over the inner shell, and the inner peripheral wall of the outer shell and the outer peripheral wall of the inner shell are spaced apart to form a medium chamber for storing an atomizing medium. The inner shell forms an atomizing chamber, and the bottom end of the inner shell forms a liquid inlet, which connects the medium chamber and the atomizing chamber. The position of the medium chamber corresponding to the top of the inner shell is designated as the first end, and the position of the medium chamber corresponding to the liquid inlet is designated as the second end. The cross-sectional area of ​​the medium chamber at the second end is greater than the cross-sectional area of ​​the medium chamber at the first end.

[0005] In one possible design, the cross-sectional area of ​​the media chamber gradually increases from the first end to the second end.

[0006] In one possible design, the cross-sectional area of ​​the media chamber increases and then decreases from the first end to the second end.

[0007] In one possible design, the cross-sectional area of ​​the media chamber varies linearly from the first end to the second end.

[0008] In one possible design, the cross-sectional area of ​​the media chamber varies in a curve from the first end to the second end.

[0009] In one possible design, the cross-sectional area of ​​the media chamber varies in a stepped manner from the first end to the second end.

[0010] In one possible design, the outer peripheral wall of the inner shell extends from the first end to the second end along an inclined line, a curve, or a stepped line, and the inner peripheral wall of the outer shell extends from the first end to the second end along a straight line.

[0011] Alternatively, the outer peripheral wall of the outer shell extends from the first end to the second end along an inclined line, a curve, or a stepped line, and the inner peripheral wall of the inner shell extends from the first end to the second end along a straight line.

[0012] Alternatively, the outer peripheral wall of the inner shell extends from the first end to the second end along an inclined line, a curve, or a stepped line, and the inner peripheral wall of the outer shell extends from the first end to the second end along an inclined line, a curve, or a stepped line.

[0013] In one possible design, the cross-sectional shape of the inner shell remains unchanged from the first end to the second end;

[0014] The cross-sectional shape of the outer shell remains unchanged from the first end to the second end.

[0015] In one possible design, the inner shell has a first side, a second side, a third side, and a fourth side connected in sequence, with the first side and the third side facing each other, and the second side and the fourth side facing each other; the atomizing chamber is formed in the inner shell near the first side, and the liquid inlet is formed on the first side; the first side extends from the first end to the second end along an inclined line, a curve, or a stepped line; the second side, the third side, and the fourth side all extend along a straight line.

[0016] In one possible design, an injection port is formed at the top of the outer shell, and a flow channel is formed between the top sidewall of the outer shell and the top sidewall of the inner shell. The top of the flow channel communicates with the injection port, and the bottom of the flow channel communicates with the medium chamber.

[0017] The beneficial effects of the electronic atomizing device provided in this application are as follows: By making the cross-sectional area of ​​the medium chamber at the second end larger than that at the first end, that is, making the liquid storage space at the liquid inlet of the medium chamber larger than that at the top of the medium chamber, the lateral pressure on the liquid at the liquid inlet is smaller, which helps to improve the fluidity of the atomizing medium in the medium chamber. This promotes the movement of the atomizing medium towards the liquid inlet, enabling the medium chamber to supply liquid to the atomizing chamber in a timely manner. This avoids the problem of dry burning of the atomizing core due to untimely delivery of the atomizing medium, reduces the possibility of damage to the atomizing core, and improves the user's safety.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0035] Please see Figures 1 to 3The electronic atomizing device provided in the embodiments of this application will now be described. This electronic atomizing device is used to heat and atomize an atomizing medium to form a mist that can be inhaled by a user.

[0036] The electronic atomizing device housing assembly 100 includes an inner shell 110 and an outer shell 120. The outer shell 120 is fitted over the inner shell 110. The inner peripheral wall of the outer shell 120 and the outer peripheral wall of the inner shell 110 are spaced apart to form a medium chamber 140 for storing the atomizing medium. An atomizing chamber 111 is formed on the inner shell 110. A liquid inlet 112 is formed at the bottom end of the inner shell 110, and the liquid inlet 112 connects the medium chamber 140 and the atomizing chamber 111. For ease of description, the position of the medium chamber 140 corresponding to the top of the inner shell 110 is designated as the first end, and the position of the medium chamber 140 corresponding to the liquid inlet 112 is designated as the second end. The cross-sectional area of ​​the medium chamber 140 at the second end is greater than the cross-sectional area of ​​the medium chamber 140 at the first end.

[0037] It should be noted that the inner peripheral wall of the outer shell 120 refers to the inner side wall of the outer shell 120 extending circumferentially, excluding the inner top wall and inner bottom wall of the outer shell 120. Similarly, the outer peripheral wall of the inner shell 110 refers to the outer side wall of the inner shell 110 extending circumferentially, excluding the outer top wall and outer bottom wall of the inner shell 110. Therefore, the medium chamber 140 formed between the inner peripheral wall of the outer shell 120 and the outer peripheral wall of the inner shell 110 is... Figure 3 The space surrounding the inner shell is 110.

[0038] The atomizing chamber 111 is equipped with an atomizing core 200. The atomizing medium in the medium chamber 140 flows to the atomizing chamber 111 through the liquid inlet 112, and the atomizing medium is atomized by the atomizing core 200 to form mist.

[0039] When the cross-sectional area of ​​the media chamber 140 at the second end is greater than that at the first end, that is, when the liquid storage space at the liquid inlet 112 of the media chamber 140 is greater than the liquid storage space at the top of the media chamber 140, the lateral pressure on the liquid at the liquid inlet 112 is smaller, which helps to improve the flowability of the atomizing medium in the media chamber 140. This causes the atomizing medium to move towards the liquid inlet 112, enabling the media chamber 140 to supply liquid to the atomizing chamber 111 in a timely manner. This avoids the problem of dry burning of the atomizing core 200 due to untimely delivery of the atomizing medium, reduces the possibility of damage to the atomizing core 200, and improves the user's safety.

[0040] In one embodiment, see Figures 5 to 9The cross-sectional area of ​​the medium chamber 140 gradually increases from the first end to the second end, that is, the liquid storage space of the medium chamber 140 is set to increase from the first end to the second end. The lower the height of the medium chamber 140, the larger the storage space, which has a gradual guiding effect on the atomizing medium and can better promote the flow of the atomizing medium at the liquid inlet 112, so that the liquid can be supplied to the atomizing chamber 111 in a timely manner and the atomizing core 200 can be prevented from burning dry.

[0041] In another embodiment of this application, please refer to Figure 10 The cross-sectional area of ​​the media chamber 140 increases and then decreases from the first end to the second end. In this embodiment, the first requirement is that the cross-sectional area of ​​the media chamber 140 at the second end is greater than that at the first end. Since the liquid inlet 112 is at the bottom, the atomizing medium will flow from the top to the liquid inlet 112 according to the fluidity of the liquid. Furthermore, the larger cross-sectional area at the second end further promotes the flow of the atomizing medium from the first end to the liquid inlet 112. Therefore, when the cross-sectional area of ​​the media chamber 140 increases and then decreases from the first end to the second end, the initial increase in cross-sectional area increases the fluidity of the atomizing medium, while the subsequent decrease does not affect the fluidity of the atomizing medium. In addition, the cross-sectional area of ​​the medium chamber 140 can be gradually increased from the first end to the position near the liquid inlet 112, so that the atomizing medium can be guided to the vicinity of the liquid inlet 112 at the fastest speed, and then gradually decreased from the position near the liquid inlet 112 to the liquid inlet 112, thereby ensuring that the atomizing medium at the liquid inlet 112 has high fluidity.

[0042] In one embodiment, see Figure 5 The cross-sectional area of ​​the media chamber 140 changes linearly from the first end to the second end.

[0043] Let the first end of the media chamber 140 be the starting point, and the distance downward from the first end be X; let the initial value of the cross-sectional area of ​​the media chamber 140 at the first end be a, and the cross-sectional panel at a distance X downward from the first end be Y. Then, the linear change means that the relationship graph with X as the abscissa and Y as the ordinate is a straight line, that is, the ratio of the change value of the cross-sectional area of ​​the media chamber 140 to the change value of the axial distance is a constant value.

[0044] When the cross-sectional area of ​​the media chamber 140 gradually increases from the first end to the second end, the linear change means that the ratio of the increase in the cross-sectional area of ​​the media chamber 140 to the increase in the axial distance from the first end to the second end is a positive value. The closer to the liquid inlet 112, the larger the cross-sectional area of ​​the media chamber 140, and the closer to the first end, the smaller the cross-sectional area of ​​the media chamber 140.

[0045] When the cross-sectional area of ​​the medium chamber 140 first increases and then decreases from the first end to the second end, the linear change means that from the first end to the inlet 112, the ratio of the increase in the cross-sectional area of ​​the medium chamber 140 to the increase in the axial distance is first positive and then negative.

[0046] In another embodiment of this application, please refer to Figure 6 The cross-sectional area of ​​the media chamber 140 changes in a curve from the first end to the second end.

[0047] A curvilinear change refers to a situation where the ratio of the change in cross-sectional area to the change in axial distance continuously changes; for example, the ratio may gradually increase, gradually decrease, increase first and then decrease, or decrease first and then increase. Specifically, when the change in axial distance is taken as the X-axis and the change in cross-sectional area as the Y-axis, the relationship between X and Y will exhibit an arc, curve, or parabola-like change.

[0048] As the cross-sectional area of ​​the medium chamber 140 gradually increases from the first end to the second end, the cross-sectional area of ​​the medium chamber 140 gradually increases in a curved manner from the first end to the liquid inlet 112.

[0049] When the cross-sectional area of ​​the medium chamber 140 increases and then decreases from the first end to the liquid inlet 112, the cross-sectional area of ​​the medium chamber 140 from the first end to the liquid inlet 112 forms a curve that first gradually increases and then gradually decreases.

[0050] In another embodiment of this application, please refer to Figure 7 The cross-sectional area of ​​the medium chamber 140 changes in a stepped manner from the first end to the second end.

[0051] The term "stepped change" refers to the fact that when the axial distance is taken as the X-axis and the cross-sectional area is taken as the Y-axis, the relationship between the axial distance and the cross-sectional area is stepped. In other words, as the axial distance changes, the cross-sectional area of ​​the media chamber 140 changes in segments. For example, in the first segment, the cross-sectional area of ​​the media chamber 140 remains unchanged. Then in the second segment, the cross-sectional area of ​​the media chamber 140 is larger than that in the first segment, but the cross-sectional area remains unchanged at every point in the second segment, and so on.

[0052] As the cross-sectional area of ​​the medium chamber 140 gradually increases from the first end to the inlet 112, the cross-sectional area of ​​each segment from the first end to the inlet 112 is larger than the cross-sectional area of ​​the previous segment.

[0053] When the cross-sectional area of ​​the medium chamber 140 first increases and then decreases from the first end to the inlet 112, the cross-sectional area of ​​each segment from the first end to the point of maximum cross-sectional area is larger than the cross-sectional area of ​​the previous segment; then from the point of maximum cross-sectional area to the inlet 112, the cross-sectional area of ​​each segment is smaller than the cross-sectional area of ​​the previous segment.

[0054] In one embodiment, the outer peripheral wall of the inner shell 110 extends from the first end to the second end along an inclined line, a curve, or a stepped line, while the inner peripheral wall of the outer shell 120 extends from the first end to the second end along a straight line. That is, the change in the cross-sectional area of ​​the entire media chamber 140 is achieved solely through the concavity or convexity of the outer peripheral wall of the inner shell 110, while the inner peripheral wall of the outer shell 120 remains straight from top to bottom and does not change.

[0055] Specifically, when the cross-sectional area of ​​the medium chamber 140 changes linearly, the outer peripheral wall of the inner shell 110 shrinks inward along the inclined line from the first end to the liquid inlet 112, or the outer peripheral wall of the inner shell 110 first shrinks inward along the inclined line from the first end to the liquid inlet 112 and then expands outward along the inclined line.

[0056] When the cross-sectional area of ​​the medium chamber 140 changes non-linearly, the outer peripheral wall of the inner shell 110 shrinks inward along the curve from the first end to the liquid inlet 112, or the outer peripheral wall of the inner shell 110 first shrinks inward along the curve from the first end to the liquid inlet 112 and then expands outward along the curve.

[0057] When the cross-sectional area of ​​the medium chamber 140 changes in a stepped manner, the outer peripheral wall of the inner shell 110 shrinks inward in a stepped manner from the first end to the liquid inlet 112, or the outer peripheral wall of the inner shell 110 first shrinks inward in a stepped manner from the first end to the liquid inlet 112 and then expands outward in a stepped manner.

[0058] In another embodiment of this application, please refer to Figure 8 The outer peripheral wall of the outer shell 120 extends along an inclined line, curve, or stepped line from the first end to the liquid inlet 112, while the inner peripheral wall of the inner shell 110 extends along a straight line from the first end to the liquid inlet 112. That is, the change in the cross-sectional area of ​​the entire medium chamber 140 is achieved solely by the concavity or convexity of the inner peripheral wall of the outer shell 120, while the outer peripheral wall of the inner shell 110 remains straight from top to bottom without change.

[0059] In yet another embodiment of this application, please refer to Figure 9The outer peripheral wall of the inner shell 110 extends along an inclined line, curve, or stepped line from the first end to the liquid inlet 112, and the inner peripheral wall of the outer shell 120 extends along an inclined line, curve, or stepped line from the first end to the liquid inlet 112. That is, the undulations of the inner peripheral wall of the outer shell 120 and the outer peripheral wall of the inner shell 110 together achieve the change of the cross-sectional area of ​​the entire media chamber 140, which allows the inner and outer sides of the media chamber 140 to change synchronously, balancing the forces on both sides of the atomized medium and improving the flow guiding effect.

[0060] In one embodiment, the cross-sectional shape of the outer peripheral wall of the inner shell 110 remains unchanged from the first end to the second end. That is, from the top end to the liquid inlet 112, the change at any point along the circumferential direction on the outer peripheral wall of the inner shell 110 is the same, thereby making the cross-sectional area of ​​the medium chamber 140 change uniformly along the circumferential direction of the inner shell 110.

[0061] In one embodiment, the cross-sectional shape of the inner peripheral wall of the outer shell 120 remains unchanged from the first end to the second end. That is, from the top end to the liquid inlet 112, the change of any point along the circumferential direction of the outer peripheral wall of the outer shell 120 is the same, so that the cross-sectional area of ​​the medium chamber 140 changes uniformly along the circumferential direction of the inner shell 110.

[0062] In another embodiment of this application, please refer to Figure 4 The inner shell 110 is generally flat and has a first side 115, a second side 116, a third side 117, and a fourth side 118 connected sequentially along its circumference. The first side 115 and the third side 117 are arranged opposite each other, and the second side 116 and the fourth side 118 are arranged opposite each other. The distance between the first side 115 and the second side 116 is smaller than the distance between the second side 116 and the fourth side 118. The atomizing chamber 111 is formed in the inner shell 110 near the first side 115, and the liquid inlet 112 is formed on the first side 115. The second side 116, the third side 117, and the fourth side 118 of the inner shell 110 are all straight surfaces, and the first side 115 of the inner shell 110 changes along an inclined straight line, a curve, or a stepped shape from the first end to the second end.

[0063] Specifically, the inlet 112 extends from the second side 116 near the first side 115, through the first side 115, to the fourth side 118 near the first side 115.

[0064] In one embodiment, see Figure 3 An injection port 1221 is formed on the top of the outer shell 120. A flow channel 150 is formed between the top sidewall of the outer shell 120 and the top sidewall of the inner shell 110. The top of the flow channel 150 is connected to the injection port 1221, and the bottom of the flow channel 150 is connected to the medium chamber 140.

[0065] Specifically, the top of the outer shell 120 is higher than the top of the inner shell 110, and the top sidewall of the outer shell 120 is located above the top sidewall of the inner shell 110. The top sidewalls of the outer shell 120 and the top sidewalls of the inner shell 110 are spaced apart to form a flow channel 150, and the inlet 1221 is formed on the top sidewall of the outer shell 120. When the atomizing medium in the medium chamber 140 is insufficient, the atomizing medium can be added through the inlet 1221 to the flow channel 150. The atomizing medium flows to the medium chamber 140 for storage through the flow channel 150, and the medium chamber 140 continuously supplies atomizing medium to the atomizing chamber 111 to prevent the atomizing coil 200 from burning dry.

[0066] In another embodiment of this application, the top of the outer shell 120 is flush with the top of the inner shell 110, and an injection port 1221 communicating with the medium chamber 140 is provided on the side wall of the outer shell 120. That is, in this embodiment, a flow channel 150 is not formed between the top of the outer shell 120 and the top of the inner shell 110, but the atomizing medium is directly injected into the medium chamber 140 through the injection port 1221 on the side wall of the outer shell 120, and then flows to the atomizing chamber 111 through the medium chamber 140.

[0067] In one embodiment, see Figure 3 The outer shell 120 includes a main body 121, a mouthpiece 122 formed on the top outer side of the main body 121, and a connecting portion 123 extending from the top inner side of the main body 121 toward the inner shell 110. A through hole 114 is formed on the top of the inner shell 110 for insertion of the connecting portion 123. The main body 121, the mouthpiece 122, and the connecting portion 123 are integrally connected. The mouthpiece 122 communicates with the atomizing chamber 111 through the connecting portion 123. The mist formed by the atomization of the atomizing medium in the atomizing chamber 111 flows through the connecting portion 123 to the mouthpiece 122 and is inhaled by the user.

[0068] Please see Figure 3 The connection between the connecting part 123 and the inner shell 110 is fitted with a sealing sleeve 900, and the sealing sleeve 900 achieves a sealed connection between the connecting part 123 and the inner shell 110.

[0069] Please see Figure 2 and Figure 3 The suction nozzle 122 is fitted onto the suction nozzle sleeve 180, which covers the injection port 1221. A plug 181 extends from the suction nozzle sleeve 180 towards the injection port 1221. When the suction nozzle sleeve 180 is fitted onto the suction nozzle 122, the plug 181 is inserted into the injection port 1221, thus concealing the injection port 1221. Specifically, a second sealing member 1000 abuts between the suction nozzle sleeve 180 and the suction nozzle 122 to achieve a sealed fit of the suction nozzle sleeve 180.

[0070] Please see Figure 2 and Figure 3The mouthpiece cover 180 is also covered by a protective cover 190. The protective cover 190 is used to protect the mouthpiece cover 180 and also to prevent external substances from entering the atomizing chamber 111 through the mouthpiece cover 180.

[0071] In one embodiment, see Figure 2 and Figure 3 The electronic atomizing device also includes a battery 500 and a control board 600. A battery compartment 113 is also formed in the inner shell 110. The battery 500 and the control board 600 are both located in the battery compartment 113. The battery 500 is electrically connected to the control board 600, and the atomizing core 200 is electrically connected to the control board 600. The battery 500 supplies power to the atomizing core 200, thereby enabling the atomizing core 200 to heat up and atomize the atomizing medium into mist.

[0072] Please see Figure 2 and Figure 3 The electronic atomizing device also includes a bottom shell 130, which is sealed to the bottom of the inner shell 110 and sealed to the bottom of the outer shell 120.

[0073] Please see Figure 2 and Figure 3 The electronic atomizing device also includes an airflow sensor 700, which is electrically connected to the control board 600. An airflow channel 131 is formed on the bottom shell 130, with one end of the airflow channel 131 communicating with the outside of the bottom shell 130 and the other end communicating with the atomizing chamber 111. The airflow sensor 700 is located in the airflow channel 131. When the user inhales through the mouthpiece 122, external air pressure enters through one end of the airflow channel 131 and passes through the airflow sensor 700. The airflow sensor 700 detects the air pressure change and feeds it back to the control board 600. The control board 600 electrically connects the battery 500 to the atomizing core 200, thereby powering the atomizing core 200 through the battery 500 to achieve atomization. When the user stops inhaling, the airflow sensor 700 no longer detects the air pressure change and feeds it back to the control board 600. The control board 600 then disconnects the battery 500 from the atomizing core 200, thereby stopping atomization.

[0074] Please see Figure 3 The atomizing chamber 111 and the battery compartment 113 are horizontally spaced apart. The bottom shell 130 is provided with a reserved chamber 132 and an airflow channel 131 corresponding to the atomizing chamber 111 and the battery compartment 113, respectively. The reserved chamber 132 is located below the atomizing chamber 111, and the airflow channel 131 is located below the battery compartment 113. The reserved chamber 132 and the airflow channel 131 are connected. The atomizing core 200 can be electrically connected to the control board 600 through the reserved chamber 132, and the airflow channel 131 can be connected to the atomizing chamber 111 through the reserved chamber 132.

[0075] Please see Figure 3The reserved compartment 132 is equipped with asbestos 400, which is used to absorb and store the atomizing medium dripping from the atomizing core 200 for later use.

[0076] Please see Figure 3 The atomizing medium also includes a charging base 800, which is located on the bottom shell 130 and is electrically connected to the control board 600. When the battery 500 is out of power, it can be charged through the charging base 800 to ensure that the electronic atomizing device can be used normally.

[0077] Please see Figure 2 and Figure 3 The electronic atomizing device also includes a decorative sleeve 160, which is fitted over the bottom shell 130. The decorative sleeve 160 has clearance holes at the positions corresponding to the airflow channel 131 and the charging base 800. The decorative sleeve 160 is used to decorate the bottom appearance of the electronic atomizing device.

[0078] Please see Figure 2 and Figure 3 The electronic atomizing device also includes a first sealing element 170, which includes a base plate 171 and an outer plate 172. The base plate 171 is annular, and the outer plate 172 extends upward from the outer edge of the base plate 171. The base plate 171 abuts between the bottom end of the inner shell 110 and the top end of the bottom shell 130, and the outer plate 172 abuts between the bottom end of the outer shell 120 and the bottom end of the inner shell 110. Thus, the first sealing element 170 can achieve a sealed connection between the inner shell 110 and the outer shell 120, and at the same time achieve a sealed connection between the outer shell 120 and the bottom shell 130.

[0079] Please see Figure 2 and Figure 3 The atomizing chamber 111 contains an atomizing tube 300, and an atomizing core 200 is disposed within the atomizing tube 300. The atomizing tube 300 has a connection port at the position of the liquid inlet 112. The atomizing medium enters the atomizing tube 300 through the liquid inlet 112 and the connection port to atomize the atomizing core 200. The first sealing member 170 also includes an inner side plate 173, which is formed on the inner side of the bottom plate 171 and is annular in shape corresponding to the atomizing chamber 111. The inner side plate 173 extends into the atomizing chamber 111 and abuts against the outer wall of the atomizing tube 300 and the inner wall of the atomizing chamber 111, thereby achieving a sealed connection between the atomizing tube 300 and the inner shell 110.

[0080] The inner side plate 173 is used to achieve a seal between the atomizing tube 300 below the liquid inlet 112 and the inner shell 110. (See also...) Figure 2 and Figure 3Located above the liquid inlet 112, a third sealing element 1100 is also abutted between the atomizing tube 300 and the inner wall of the atomizing chamber 111, thereby achieving a seal between the upper and lower ends of the atomizing tube 300 and the atomizing chamber 111.

[0081] In addition, please see Figure 2 and Figure 3 A fourth sealing element 1200 is provided inside the bottom shell 130 at the position corresponding to the airflow sensor 700 and the charging base 800, thereby achieving sealing and buffering of the airflow sensor 700 and the charging base 800.

[0082] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
