Description

Technical Field

[0001] This invention relates to the field of electronic cigarette technology, and more specifically, to an electronic cigarette atomizing component and an electronic cigarette. Background Technology

[0002] Electronic cigarettes generally consist of a power supply unit and an atomizer. The power supply unit supplies power to the atomizer, which then heats and vaporizes the e-liquid to form vapor that the user inhales. In recent years, electronic cigarettes have gained popularity among consumers due to their convenience and perceived lower health risks.

[0003] To meet the demands of portability and ease of use, existing e-cigarettes are generally designed to be quite small. However, the numerous internal components in e-cigarettes, combined with the pursuit of miniaturization, result in overly compact internal spaces. This limited internal space severely impacts atomization efficiency and the user's vaping experience. Therefore, it is necessary to improve the internal structure of e-cigarettes and optimize the product design. Summary of the Invention

The atomizing core includes a porous body and a heating element. The porous body includes a liquid-absorbing surface, and the surface of the porous body opposite to the liquid-absorbing surface is the atomizing surface. The heating element is disposed on the atomizing surface, and the atomizing core seal is sleeved on the porous body to form a seal. Along the extension direction perpendicular to the liquid-absorbing surface to the atomizing surface, the cross-section of the upper cover is an elongated structure, the first direction being the width direction of the elongated structure; the length direction of the elongated structure is the second direction.

[0049] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0050] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0051] Reference Figures 1 to 15 This application provides an electronic cigarette atomizing component, the electronic cigarette atomizing component comprising:

[0052] The device comprises a housing 1, a lower base 2, an upper cover 3, and an atomizing core assembly. The housing 1 has a liquid storage chamber 10 inside and an air outlet channel on the housing. The liquid storage chamber 10 and the air outlet channel are isolated from each other. The liquid storage chamber 10 is used to store e-liquid.

[0053] See Figures 1 to 3 The lower base 2 is connected to the housing 1. The housing 1 can have an open lower part. The lower base 2 is connected to the lower opening of the housing 1 to form the receiving cavity. An air intake channel 22 is provided on the lower base 2.

[0054] See Figure 10 The upper cover 3 includes an upper cover body 30 and a top cover 300 located on top of the upper cover body 30. An airflow channel is provided on the upper cover body 30, and a notch 301 is provided on the top cover 300. The notch 301 is opened along the inner wall direction of the housing and surrounds the inner wall of the housing to form an air outlet.

[0055] The atomizing core assembly is disposed between the upper cover body 30 and the lower base 2. The atomizing core assembly has an atomizing surface facing the lower base 2, and an atomizing cavity 20 is formed between the atomizing surface and the lower base 2. The atomizing cavity 20 is connected to the air outlet through the airflow channel, and the air outlet is connected to the air outlet channel. The atomizing cavity 20 is also connected to the air inlet channel 22. Cold air entering from the air inlet channel 22, after encountering the atomized aerosol in the atomizing cavity 20, can carry the atomized aerosol through the airflow channel to the air outlet, and then through the air outlet to the air outlet channel for the user to inhale. The notch 301 reduces the size of the top cover 300 in the direction of the notch 301 opening, improves the space utilization of the electronic cigarette atomizing assembly, and makes the structural design of the electronic cigarette atomizing assembly more adaptable.

[0056] According to an embodiment of this application, see Figure 13 The notch is opened along the first direction S, and the airflow channel includes a first channel 31 and a second channel 32. The first channel 31 and the second channel 32 are distributed on both sides of the upper cover body 30 along the first direction S; that is, the setting direction of the notch is the same as the distribution direction of the first channel and the second channel on the upper cover body.

[0057] According to an embodiment of this application, the end face of the top cover 300 can be elongated, and the first direction is the width direction of the end face of the top cover 300, that is, the width direction of the top cover 300. The notch 301 is opened along the first direction and surrounds the inner wall of the housing 1 to form an air outlet. The airflow channel includes a first channel 31 and a second channel 32, which are distributed on both sides of the top cover body 30 along the first direction. The liquid in the liquid storage tank 10 is heated and atomized by the atomizing core assembly to form an atomized aerosol and enters the atomizing chamber. After passing through the atomizing chamber, it enters the first channel 31 and the second channel 32 and is then transported to the air outlet, and then through the air outlet to the air outlet channel to be inhaled by the user. The setting of the notch 301 allows the notch to directly cooperate with the inner wall of the housing to form an air outlet, reducing the size of the top cover 300 in the notch setting direction, improving space utilization, and making the structural design adaptability of the electronic cigarette atomizing component stronger. According to an embodiment of this application, the end face of the top cover 300 can be elongated. When the first direction is the width direction of the end face of the top cover 300, the notch allows the housing 1 to be closer to the top cover 3 in the first direction, while reducing the size of the top cover 3 and the housing 1 in the first direction, that is, reducing the width of the top cover 3 and the housing 1, making the housing 1 thinner, making the electronic cigarette more compact and more in line with the user's usage habits.

[0058] According to an embodiment of this application, since the atomizing chamber 20 is connected to the air intake channel 22, the cold air entering the atomizing chamber from the air intake channel 22, after encountering the atomized aerosol in the atomizing chamber 20, can carry the atomized aerosol through the first channel 31 and the second channel 32 of the airflow channel respectively. The atomized airflow in the first channel 31 and the second channel 32 mixes and is then delivered to the air outlet channel through the air outlet. The extending direction of the first channel 31 and the second channel 32 can be perpendicular to the end face of the upper cover body 30. After the first channel 31 and the second channel 32 form two channels on both sides of the upper cover body 30, the airflow pressure of the atomized aerosol can be balanced to ensure the flow stability of the atomized aerosol, so as to facilitate the user's inhalation.

[0059] According to an embodiment of this application, see Figure 10 and Figure 13 The upper cover body 30 has a saddle-shaped structure 34, the atomizing core assembly is fixed to the bottom side of the saddle-shaped structure 34, and the first channel 31 and the second channel 32 are distributed on both sides of the saddle-shaped structure 34 along the first direction S.

[0060] According to an embodiment of this application, an atomizing cavity 20 is formed between the atomizing surface of the atomizing core assembly and the lower base 2. The atomizing cavity 20 is connected to the air outlet through the airflow channel and to the air inlet channel 22. The bottom surface of the saddle-shaped structure 34 may have a mounting groove, in which the atomizing core assembly is fixedly installed. The mounting groove is located on the side of the saddle-shaped structure 34 closest to the atomizing cavity 20. The atomized aerosol formed by heating and atomizing on the atomizing surface of the atomizing core assembly can be mixed and transported to the air outlet channel through the first channel 31 and the second channel 32 respectively. While ensuring the stability of the atomizing core assembly, the smoothness of the atomized aerosol flow is improved through the first channel 31 and the second channel 32.

[0061] According to an embodiment of this application, at least a portion of the first channel 31 is opposite to the opening end of the notch 301; the top cover 300 has a top wall on the side opposite to the opening end of the notch 301, and at least a portion of the second channel 32 is opposite to the top wall.

[0062] Specifically, see Figures 10 to 15 When at least a portion of the first channel 31 is opposite to the opening end of the notch 301, the atomized airflow through the first channel 31 can directly enter the outlet channel through the airflow channel; while when at least a portion of the second channel 32 is opposite to the top wall, the top wall can block the atomized airflow flowing up from the second channel 32, causing the direction of the atomized airflow in the second channel 32 to change, and then merge with the airflow in the first channel 31 and enter the outlet channel.

[0063] To further explain, when the e-liquid in the atomizing chamber 20 is atomized, the first channel 31 allows the large aerosol particles atomized in the atomizing chamber 20 to flow directly into the air outlet channel through the first channel 31, greatly reducing the draw resistance of the electronic cigarette, that is, reducing the resistance when the user inhales the electronic cigarette. Moreover, the large aerosol particles can increase the saturation of the atomized airflow, restore the taste of the e-liquid, and improve the smoking experience of the electronic cigarette. Furthermore, the draw resistance of the electronic cigarette can be flexibly adjusted by the relative area of ​​the first channel 31 and the air outlet channel. For example, the draw resistance of the electronic cigarette can be adjusted by adjusting the relative size of the width of the two sides of the top cover 3 and the width of the air outlet channel inside the shell 1. When the second channel 32 is partially opposite to the top wall, during the atomization of the e-liquid in the atomizing chamber 20, the large aerosol particles atomized in the atomizing chamber 20 collide with the top wall after passing through the second channel 32, causing the large e-liquid aerosol particles to break down into smaller e-liquid aerosol particles. These smaller particles then enter the air outlet channel of the housing 1 along a curved flow trajectory. The flow velocity of the atomized aerosol after the collision is significantly reduced, which reduces condensation of the atomized aerosol and lowers the draw resistance of the electronic cigarette atomizing component.

[0064] According to an embodiment of this application, see Figure 4 The air outlet channel includes a first cavity 11 near the upper cover 3 and a second cavity 12 near the nozzle portion of the housing 1. The cross-section of the first cavity 11 is larger than the cross-section of the second cavity 12.

[0065] Specifically, the airflow direction of the air outlet channel can be... Figure 4 In the direction indicated by the middle arrow, the cross-sections of the first cavity 11 and the second cavity 12 can be perpendicular to the airflow direction of the air outlet channel. After the atomizing core assembly heats and atomizes the liquid in the storage tank 10, the large aerosol particles formed by the heating and atomization first enter the first cavity 11 through the airflow channel. The cross-sectional dimensions of the first cavity 11 can match the cross-sectional dimensions of the airflow channel, allowing the atomized aerosol passing through the airflow channel to directly enter the first cavity 11. When the cross-section of the first cavity 11 is larger than the cross-section of the second cavity 12, that is, when a large volume space is formed in the first cavity 11 on the air inlet side of the housing 1, the flow rate of the atomized aerosol can be reduced, and the condensation of the atomized aerosol can be decreased, thus adjusting the suction resistance of the electronic cigarette atomizing assembly while satisfying the user's vaping experience.

[0066] According to the embodiments of this application, the cross-section of the first cavity 11 can be U-shaped or gourd-shaped, etc., and the cross-section of the second cavity 12 is elliptical, which is convenient for the user to suck. The first cavity 11 includes a cavity with an elliptical cross-section that is directly opposite to the second cavity 12 and a cavity that is misaligned with the second cavity 12.

[0067] Additionally, the housing 1 can be made of an elastic, semi-transparent or transparent material, such as PVC or TPU. Figure 4 As shown, the lower part of the air outlet channel of the housing 1 is an airflow channel with a large volume space, which can reduce the resistance of the atomized airflow being delivered to the air outlet channel through the first channel 31 and the second channel 32.

[0068] According to an embodiment of this application, see Figure 10 and Figure 13 The notch 301 is U-shaped, V-shaped, semi-circular, small semi-circular, trapezoidal, or C-shaped.

[0069] Specifically, the open-shaped structure of the notch 301 can be understood as forming an opening in the top cover 300, and the opening extends to the edge of the top cover 300. The notch 301 facilitates the delivery of liquid in the storage tank 10 to the gas outlet channel after atomization, and also reduces the size of the top cover 3 in the first direction. A larger opening size of the notch 301 further enhances the degree of size reduction of the top cover 3 in the first direction. The cross-section of the notch 301 is perpendicular to the flow of the atomized aerosol, and when the cross-section of the notch 301 is one of the aforementioned open shapes, the larger opening of the notch 301 ensures effective size reduction of the top cover 3 in the first direction.

[0070] Furthermore, when the e-liquid in the atomizing chamber 20 is atomized, the large aerosol particles atomized in the atomizing chamber 20 collide with the top wall after passing through the second channel 32, causing the large e-liquid aerosol particles to become small e-liquid aerosol particles, which finally enter the air outlet channel of the shell 1 with a curved flow trajectory. After the large and small e-liquid aerosol particles merge in the large volume space of the air outlet channel, the aerosol flow rate decreases, thereby reducing the draw resistance of the electronic cigarette; moreover, the mixed e-liquid aerosol particles of different sizes can further improve the user's inhalation taste and enhance the user's experience of using the electronic cigarette. In addition, as the diameter of the second channel 32 gradually increases along the flow direction of the atomizing airflow, it can weaken the airflow rate of the small aerosol particles, avoiding the impact of a large airflow on the user during inhalation.

[0071] According to an embodiment of this application, see Figure 1 and Figure 2 The electronic cigarette atomizing assembly also includes an upper cover seal 4, which is sleeved on the upper cover 3 and is interference-fitted with the housing 1 and the upper cover 3 respectively.

[0072] Specifically, the upper cover seal 4 is located within the receiving cavity. The upper cover seal 4 is fitted onto the upper cover 3 to form a seal, and there is an interference fit between the upper cover seal 4 and the upper cover, as well as between the upper cover seal 4 and the inner wall of the housing 1, to fix the upper cover 3 within the housing 1, ensuring the assembly stability and sealing performance of the upper cover 3. Furthermore, the upper cover seal 4 matches the external structure of the upper cover 3. The upper cover seal 4 is fitted onto the upper cover 3, and its inner frame circumference fits tightly with the upper cover 3 to create a sealing effect. After the upper cover seal 4 and the upper cover 3 are assembled, they are inserted together into the housing 1, and the sealing ribs around the upper cover seal 4 have an interference fit with the inner wall of the housing 1.

[0073] According to an embodiment of this application, an edge-sealing structure 41 is formed on the upper cover seal 4, the outline of the edge-sealing structure 41 matches the outline of the notch 301, and the edge-sealing structure 41 is inserted into the notch 301.

[0074] Specifically, see Figures 6 to 9 The edge-sealing structure 41 is embedded in the notch 301, and the air outlet channel is connected to the atomizing chamber 20 through the edge-sealing structure 41. That is, the edge-sealing structure 41 on the atomizing core seal 6 is embedded in the notch 301, sealing the periphery of the notch 301 to prevent e-liquid from leaking out of the liquid storage tank 10. At the same time, the edge-sealing structure 41 also allows the air outlet channel and the atomizing chamber 20 to be connected through the edge-sealing structure 41, that is, the mixture of aerosol and air in the atomizing chamber can enter the air outlet channel through the edge-sealing structure 41 and then be inhaled by the user. In order to improve the sealing effect of the liquid storage tank 10 and reduce the risk of liquid leakage, the edge-sealing structure 41 is designed to provide a certain degree of sealing for the notch 301, separating the notch 301 from the liquid storage tank 10. In this way, after the edge-sealing structure 41 matches the notch 301, the cooperation between the upper cover seal 4 and the upper cover 3 can prevent e-liquid in the liquid storage tank 10 from leaking between the upper cover seal 4 and the inner wall of the housing 1.

[0075] According to an embodiment of this application, see Figure 3 The housing 1 has a plug-in portion 13 formed at the inner port of the air outlet channel, and the plug-in portion 13 is plugged into and fixed in the edge-sealing structure 41.

[0076] Specifically, when the plug-in part 13 is plugged into and fixed within the edge-sealing structure 41, the edge-sealing structure 41 forms a seal between the notch 301 and the plug-in part 13 to prevent oil leakage between the edge-sealing structure 41 and the notch 301. Plugging and fixing the plug-in part 13 of the air outlet channel into the edge-sealing structure 41 also improves the overall fixation and positioning reliability of the atomizing core seal 6 and the atomizing core 5. Through the above-mentioned plug-in fit, the air outlet channel directly communicates with the atomizing chamber 20 through the edge-sealing structure 41 and the notch 301. This air path structure is smooth and has fewer bends, which helps the atomized gas flow outwards and reduces the possibility of it cooling and forming condensate droplets.

[0077] According to an embodiment of this application, see Figure 8 and Figure 9 The edging structure 41 has a plurality of protruding ribs 411, and the edging structure 41 abuts against the outer periphery of the insertion part 13 through the protruding ribs 411.

[0078] Specifically, when the insertion part 13 is inserted and fixed in the edge-wrapping structure 41, in order to ensure the stability of the insertion fit between the insertion part 13 and the edge-wrapping structure 41, an inner protruding rib 411 can be used between the body structure of the edge-wrapping structure 41 and the insertion part 13, so that the inner protruding rib 411 tightly abuts against the insertion part 13, ensuring the reliability of the fit between the atomizing core seal 6 and the atomizing core 5 and the housing 1. Optionally, see Figures 1 to 3 The atomizing core assembly includes an atomizing core 5 and an atomizing core seal 6. The atomizing core 5 is used to heat and atomize the liquid in the liquid storage chamber 10. The atomizing core 5 includes a porous body 51 and a heating element 52. The porous body 51 includes a liquid-absorbing surface, and the surface of the porous body 51 opposite to the liquid-absorbing surface is the atomizing surface. The heating element 52 is disposed on the atomizing surface. The atomizing core seal 6 is sleeved on the porous body 51 to form a seal, and the atomizing core seal 6 and the upper cover 3, as well as the atomizing core seal 6 and the porous body 51, are all interference fits. Along the extension direction perpendicular to the liquid-absorbing surface to the atomizing surface, the upper cover 3 has an elongated cross-section, wherein the first direction is the width direction of the elongated structure, and the length direction of the elongated structure is the second direction.

[0079] According to an embodiment of this application, along the extension direction perpendicular to the liquid absorption surface to the atomizing surface, the cross-section of the upper cover 3 is elliptical, with the major axis of the ellipse pointing in the second direction W and the minor axis pointing in the first direction S. Figure 13 As shown.

[0080] Specifically, the atomizing core seal 6 is fitted onto the upper edge of the porous body 51 to form a seal for the atomizing core 5. Since the atomizing core seal 6 is interference-fitted with both the upper cover 3 and the porous body 51, the atomizing core 5 is fixed within the upper cover 3 by the atomizing core seal 6, ensuring the assembly stability and sealing performance of the atomizing core 5. The atomizing core seal 6 seals the outer wall surface of the atomizing core 5 and is interference-fitted with the inner wall of the upper cover 3, preventing e-liquid in the reservoir 10 from leaking through the gap between the atomizing core seal 6 and the upper cover 3.

[0081] According to an embodiment of this application, see Figure 10 and Figure 11 The upper cover 3 is provided with a liquid discharge channel 33, which is distributed on both sides of the notch 301 along the second direction. One end of the liquid discharge channel 33 is connected to the liquid storage tank 10, and the other end of the liquid discharge channel 33 extends to the liquid absorption surface.

[0082] Specifically, one end of the liquid discharge channel 33 is connected to the liquid storage chamber 10, and the other end of the liquid discharge channel 33 extends to the liquid absorption surface of the porous body. The cross-section of the liquid discharge channel 33 can be semi-circular, and the diameter of the liquid discharge channel 33 gradually decreases along the flow direction of the e-liquid. The e-liquid in the liquid storage chamber 10 can flow through the liquid discharge channel 33 to the atomizing core of the atomizing core assembly, so that the atomizing core assembly can heat the e-liquid and form an atomized airflow.

[0083] According to embodiments of this application, the number of the lower liquid channel 33 can be one or more, specifically determined based on the atomization amount of the electronic cigarette and the quality requirements of the inhaled product. In one embodiment of this application, see... Figure 10 There are two liquid channels 33, which are symmetrically distributed on both sides of the notch 301 along the second direction. The second direction can be the long axis direction of the upper cover 3. This can ensure the uniform mixing of aerosol particles of different sizes while balancing the atomized airflow, thereby improving the inhalation experience of the electronic cigarette.

[0084] According to an embodiment of this application, see Figure 12 and Figure 13 The ratio of the maximum dimension of the upper cover 3 in the second direction to the maximum dimension of the upper cover 3 in the first direction is (2-6):1, and the second direction is perpendicular to the first direction.

[0085] Along the extension direction perpendicular to the liquid absorption surface to the atomizing surface, the cross-section of the upper cover 3 is elongated, wherein the first direction is the width direction of the elongated structure; the second direction is the length direction of the elongated structure; according to the embodiment of this application; along the extension direction perpendicular to the liquid absorption surface to the atomizing surface, the cross-section of the upper cover 3 is elliptical, the major axis direction of the ellipse is the second direction, and the minor axis direction of the ellipse is the first direction.

[0086] When the ratio of the maximum size of the top cover 3 in the second direction to the maximum size of the top cover 3 in the first direction is controlled within the range of (2-6):1, the width of the shell 1 can be further reduced based on the reduction of the width of the top cover 3, since the structure of the top cover 3 matches that of the shell 1. This makes the shell 1 more inclined to a streamlined design with a narrower width, which meets the user's requirement for a streamlined design with a narrower width of the shell 1 and is more in line with the user's mouth shape for a better drinking experience.

[0087] Specifically, based on the dimensions of the electronic cigarette casing and the user's comfortable grip and inhalation experience, the maximum dimension of the top cover 3 in the second direction can be controlled within 10-30mm. That is, along the extension direction from the liquid-absorbing surface to the atomizing surface, the maximum dimension of the cross-section of the top cover 3 in the length direction is controlled within 10-30mm. The maximum dimension of the top cover 3 in the first direction is controlled within 5-12mm. That is, along the extension direction from the liquid-absorbing surface to the atomizing surface, the maximum dimension of the cross-section of the top cover 3 in the width direction is controlled within 5-12mm. When the width of the top cover 3 is significantly smaller than its length, the flatness of the top cover 3 can be ensured, which is beneficial for the streamlined design of the casing 1.

[0088] Additionally, see Figures 1 to 3 According to an embodiment of this application, a lower base 2 is circumferentially provided with a lower base seal 23, which abuts against the inner wall of the housing 1 and forms a seal between the lower base 2 and the inner wall of the housing 1. The lower base 2 is also provided with an oil-absorbing body 8, which is arranged around the outer periphery of the air intake channel 22. This effectively prevents cooled liquid from being inhaled by the user with the smoke or leaking out from the air intake channel 22.

[0089] According to an embodiment of this application, the heating element 52 is electrically connected to the conductive pin 21 through the electrical connector 7. The conductive pin 21 has an end face exposed outside the electronic cigarette atomizing assembly. An external power source can supply power to the heating element 52 through the conductive pin 21, thereby realizing the conversion of electrical energy and thermal energy on the heating element 52, and thus atomizing the e-liquid.

[0090] According to an embodiment of this application, see Figures 1 to 3The electronic cigarette atomizing component also includes an electrical connector 7, one end of which extends into the porous body 51 and is electrically connected to the heating element 52. A conductive nail 21 is provided on the lower base 2, and one end of the conductive nail 21 extends into the lower base 2 and abuts against the other end of the electrical connector 7.

[0091] This application embodiment also provides an electronic cigarette, including the aforementioned electronic cigarette atomizing component and power supply. The power supply can supply power to the heating element 52 through the conductive pin 21 and the electrical connector 7, thereby realizing the conversion of electrical energy and thermal energy in the heating element 52.

[0092] When a user uses an electronic cigarette, they inhale through the outlet. External air enters the atomizing chamber 20 through the air intake channel 22. Sensors inside the electronic cigarette detect the user's inhalation, establishing an electrical connection between the power supply and the heating element 52, supplying power to the heating element 52 to heat the liquid in the atomizing reservoir 10, forming vapor. Air entering the atomizing chamber 20 carries the vapor through the outlet channel and outlet, where it is inhaled by the user. The air entering the atomizing chamber 20 causes the vapor to condense and form condensate, which is absorbed by the absorbent body 8, preventing the liquid from being carried away by the vapor and inhaled by the user, or from accumulating too much liquid and causing leakage.

[0093] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application. The scope of this application is defined by the appended claims.
