Description

Technical Field

[0001] This application relates to the field of atomization product technology, specifically to an electronic atomizer. Background Technology

[0002] Electronic atomizers are electronic products used to heat and atomize liquids into aerosols. Currently, traditional electronic atomizers have only one liquid tank, which can only hold one type of liquid. If users need to use other types of liquids, they need to disassemble the electronic atomizer to change the liquid, which is cumbersome, time-consuming, and laborious. Repeated disassembly and reassembly can easily affect the sealing performance of the electronic atomizer and the product's performance.

[0003] In existing technologies, although there are electronic atomizers with multiple oil tanks, the isolation effect between adjacent oil tanks is poor, which can easily cause multiple oils to mix and affect the user experience. Utility Model Content

[0004] In view of this, this application provides an electronic atomizer that can prevent cross-contamination of different types of oil in different oil tanks, thereby improving the user experience.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] An electronic atomizer includes an oil cup having n oil reservoirs and an atomizing component connected to the oil cup, where n is a positive integer greater than or equal to 2;

[0007] The atomizing component includes an atomizing bracket, an airway bracket, a heating element, and an oil guiding element. The oil guiding element has a support portion and n oil guiding portions connected to the support portion. The n oil guiding portions are arranged along the outer periphery of the airway bracket. The heating element is provided with n elements and abuts against the oil guiding portions and the airway bracket one-to-one.

[0008] The atomizing bracket is provided with a mounting groove, the air passage bracket is disposed in the mounting groove, the oil guide part is pressed between the side wall of the mounting groove and the air passage bracket, the support part is pressed between the bottom wall of the mounting groove and the air passage bracket, and the compression ratio of the support part is less than the compression ratio of the oil guide part.

[0009] Optionally, a compression structure is provided between the bottom wall of the atomizing bracket and the airway bracket, and the support part is compressed by the compression structure so that the compression ratio of the support part is less than the compression ratio of the oil guide part.

[0010] Optionally, the extrusion structure includes a protruding ridge, which is disposed on the bottom wall of the mounting groove and / or the airway support.

[0011] Optionally, the side of the protruding ridge closest to the support portion is a plane, and the width of the protruding ridge gradually increases in the direction away from the support portion.

[0012] Optionally, a partition structure is provided between the side wall of the atomizing bracket and the airway bracket, and the partition structure is provided between any two adjacent oil guides.

[0013] Optionally, the partition structure includes a protrusion and a groove for the protrusion to be inserted into, one of the protrusion and the groove being disposed on the atomizing bracket and the other on the airway bracket, and the extending direction of the protrusion and the groove being perpendicular to the circumferential direction of the airway bracket.

[0014] Optionally, the protrusion is disposed on the airway support, and the atomizing support is provided with a limiting part that abuts against the protrusion.

[0015] Optionally, the compression ratio of the support portion is 30-60%, and the compression ratio of the oil guide portion is 70-90%.

[0016] Optionally, two oil tanks, two oil guides, and two heating elements are provided. The two heating elements are respectively located on opposite sides of the air passage component, and the two oil guides are respectively located on opposite sides of the air passage component.

[0017] Optionally, the device also includes a base assembly having a first electrode and two second electrodes, the heating element having a first contact portion and a second contact portion, the first electrode being connected to the two first contact portions, and the two second electrodes being connected one-to-one to the two second contact portions.

[0018] The electronic atomizer provided in this application requires the heating element and the wicking element to be assembled onto the airflow support first during installation. The wicking portion of the wicking element abuts against the side of the airflow support, and the supporting portion abuts against the first end face of the airflow support. Then, the atomizing core, consisting of the airflow support, heating element, and wicking element, is embedded in the mounting groove of the atomizing support. At this point, the wicking element is compressed, thus fixing the atomizing core within the mounting groove of the atomizing support. The compression ratio of the supporting portion of the wicking element is less than that of the wicking portion; that is, the degree of compression of the supporting portion is greater than that of the wicking portion. This prevents the wicking fluid from easily passing through the supporting portion from different wicking portions. In other words, the supporting portion, when compressed, does not function as a wicking element, thereby isolating the wicking fluid from different wicking portions and preventing cross-contamination of different types of wicking fluid in different tanks, which improves the user experience.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] like Figures 1-12 As shown in the figure, this application provides an electronic atomizer, including an oil cup 1, an atomizing component 2, and a base component 3. Both the atomizing component 2 and the base component 3 are connected to the oil cup 1. For example, the atomizing component 2 and the base component 3 are integrated and housed together inside the oil cup 1, and then sealed inside the oil cup 1 by a bottom cover 4. The oil cup 1 has multiple oil reservoirs 11 for storing oil. The number of oil reservoirs 11 is set to n, where n is a positive integer greater than or equal to 2. For example, the number of oil reservoirs 11 can be two, three, or four. These n oil reservoirs 11 can be arranged circumferentially around the oil cup 1 so that each oil reservoir 11 can be individually connected to the atomizing component 2. In addition, an air outlet channel 12 is provided in the center of the oil cup 1, and the multiple oil reservoirs 11 are arranged circumferentially around the air outlet channel 12.

[0035] The atomizing assembly 2 includes an atomizing bracket 21, an airflow bracket 22, a heating element 24, and an oil guide 23. The atomizing bracket 21 has a mounting groove 211 and multiple oil outlet channels 215 arranged circumferentially around the mounting groove 211. When the atomizing assembly 2 is connected to the oil cup 1, each oil outlet channel 215 communicates one-to-one with the oil reservoir 11 in the oil cup 1. The airflow bracket 22, the heating element 24, and the oil guide 23 constitute the atomizing core, which is embedded inside the mounting groove 211 of the atomizing bracket 21. A bracket silicone 25 is provided at the end of the atomizing bracket 21, surrounding its outer periphery. When the atomizing assembly 2 is connected to the oil cup 1, the bracket silicone 25 acts as an airflow seal.

[0036] The oil guide component 23 has a support portion 232 and an oil guide portion 231. There are multiple oil guide portions 231, and the number of oil guide portions 231 is set to n. All n oil guide portions 231 are connected to the support portion 232. For example, the n oil guide portions 231 are distributed and connected along the circumference of the support portion 232. When there are two oil guide portions 231, the two oil guide portions 231 are respectively connected to the opposite sides of the support portion 232. When there are four oil guide portions 231, the four oil guide portions 231 are respectively connected to the four sides of the support portion 232.

[0037] Furthermore, n oil guiding parts 231 are arranged circumferentially along the airway support 22 and adhere to the side of the airway support 22. In a specific design, an atomizing channel 221 is provided through the middle of the airway support 22. When the atomizing component 2 is connected to the oil cup 1, the atomizing channel 221 communicates with the air outlet channel 12 in the oil cup 1. The circumference of the atomizing support 21 is the circumference of the atomizing channel 221. Multiple mounting surfaces are arranged along the circumference of the atomizing channel 221 on the outer periphery of the airway support 22. The number of mounting surfaces is n, and the n oil guiding parts 231 are arranged one-to-one on the n mounting surfaces. Correspondingly, n heating elements 24 are provided. Each heating element 24 abuts between the mounting surface of the airway support 22 and the oil guiding part 231 of the oil guiding component 23, so that the heating element 24 can heat and atomize the oil on the oil guiding part 231 into an aerosol.

[0038] The airway support 22 has a first end face and a second end face. The first end face of the airway support 22 is close to the bottom wall of the mounting groove 211 of the atomizing support 21. The mounting surface of the side of the airway support 22 is close to the side wall of the mounting groove 211 of the atomizing support 21, so that the oil guiding part 231 of the oil guiding member 23 is pressed between the side wall of the mounting groove 211 and the mounting surface of the airway support 22, and the support part 232 of the oil guiding member 23 is pressed between the bottom wall of the mounting groove 211 and the first end face of the airway support 22. During installation, the heating element 24 and the oil guide 23 need to be assembled on the airway bracket 22 first. The oil guide part 231 of the oil guide 23 abuts against the side of the airway bracket 22, and the support part 232 of the oil guide 23 abuts against the first end face of the airway bracket 22. Then, the atomizing core composed of the airway bracket 22, the heating element 24 and the oil guide 23 is embedded in the mounting groove 211 of the atomizing bracket 21. At this time, the oil guide 23 is compressed by the pressure so that the atomizing core is squeezed and fixed in the mounting groove 211 of the atomizing bracket 21.

[0039] In this case, the compression ratio of the support portion 232 of the oil guide 23 is less than that of the oil guide portion 231. The compression ratio here is the ratio of the thickness of the oil guide 23 after being compressed to its thickness before being compressed. That is, the degree of compression of the support portion 232 of the oil guide 23 is greater than that of the oil guide portion 231. This makes it difficult for the oil on different oil guide portions 231 to be transmitted through the support portion 232. In other words, the support portion 232 does not play the role of oil guide after being compressed, thereby isolating the oil on different oil guide portions 231 and preventing the oil passages of different types of oil in different oil tanks 11 from being interconnected, which is conducive to improving the user experience.

[0040] In the specific design, the compression ratio of the support portion 232 is 30-60%, and the compression ratio of the oil guiding portion 231 is 70-90%. Preferably, the compression ratio of the support portion 232 is 50%, and the compression ratio of the oil guiding portion 231 is 80%. This allows the oil guiding portion 231 to have good oil guiding performance, while also allowing the support portion 232 to have good oil separating performance.

[0041] It should be noted that, when the thickness of the support portion 232 and the oil guiding portion 231 on the oil guiding component 23 is the same, in order to make the compression ratio of the support portion 232 less than the compression ratio of the oil guiding portion 231, the distance 'a' between the first end face of the airway support 22 and the bottom wall of the mounting groove 211 of the atomizing support 21 can be made smaller than the distance 'b' between the mounting surface of the airway support 22 and the side wall of the mounting groove 211 of the atomizing support 21. For example, the distance 'a' between the first end face of the airway support 22 and the bottom wall of the mounting groove 211 of the atomizing support 21 is 0.3 mm, and the distance 'b' between the mounting surface of the airway support 22 and the side wall of the mounting groove 211 of the atomizing support 21 is 0.8 mm.

[0042] Since there are n oil tanks 11, oil guides 231, and heating elements 24, and they are arranged in a one-to-one correspondence, the oil in each oil tank 11 can pass through different oil guides 231 and heating elements 24. That is, the oil path in each oil tank 11 is different, so as to avoid affecting the user experience quality due to oil cross-contamination. The following is a specific explanation using an n=2 example, that is, there are two oil tanks 11, two oil guides 231, and two heating elements 24. The two heating elements 24 are respectively arranged on opposite sides of the air passage support 22, and the two oil guides 231 are respectively arranged on opposite sides of the air passage support 22. During processing, the air passage support 22 can be set as square or plate-shaped, with a simple structure, easy to process, and conducive to improving the connection stability of the heating elements 24 and oil guides 231.

[0043] In some embodiments, a compression structure is provided between the bottom wall of the atomizer and the first end face of the airway support 22. When the atomizer support 21 and the airway support 22 are connected, the compression structure compresses the support portion 232 of the oil guide portion 231, so that the compression ratio of the support portion 232 is less than that of the oil guide portion 231. Here, the extension direction of the compression structure can be perpendicular to the arrangement direction of the two oil guide portions 231, and the support portion 232 of the oil guide member 23 is compressed and divided into two parts, which are respectively close to the two oil guide portions 231. In this way, the oil guiding performance of the support portion 232 of the oil guide member 23 can be further reduced by the added compression structure, and the oil on different oil guide portions 231 can be prevented from being transferred through the support portion 232. Here, the compression structure can be set as a compression pad or compression protrusion, etc.

[0044] The extrusion structure includes a protruding rib 212. One protruding rib 212 can be provided and disposed on the bottom wall of the mounting groove 211 of the atomizing bracket 21 or the first end face of the airway bracket 22, so that the protruding rib 212 can abut against the first end face of the airway bracket 22 or the bottom wall of the mounting groove 211 of the atomizing bracket 21, clamping the support portion 232 of the oil guide member 23. Alternatively, two protruding ribs 212 can be provided, respectively disposed on the bottom wall of the mounting groove 211 of the atomizing bracket 21 and the first end face of the airway bracket 22, so that the two protruding ribs 212 clamp the support portion 232 of the oil guide member 23.

[0045] Understandably, the length of the protruding rib 212 needs to be greater than or equal to the size of the support portion 232 of the oil guide 23, so that the protruding rib 212 can completely clamp the support portion 232 and prevent oil from flowing through the support portion 232. Moreover, since an atomizing channel 221 is provided through the airway support 22, and one end of the atomizing channel 221 is located on the first end face of the airway support 22, the protruding rib 212 is provided with a clearance section at the position of the atomizing channel 221.

[0046] like Figure 4 As shown, the side of the protruding ridge 212 closest to the support portion 232 is a flat surface, allowing the ridge 212 to press the support portion 232 tightly through this flat surface, which helps to increase the pressing area and the isolation effect. Furthermore, the width of the ridge 212 gradually increases in the direction away from the support portion 232. This prevents abrupt changes in the thickness of the support portion 232 when the ridge 212 presses against it, thus protecting the oil guide 23 and preventing the support portion 232 from being crushed, which would affect subsequent use.

[0047] In a specific design, the cross-sectional shape of the protruding ridge 212 can be set as an isosceles trapezoid or a frustum shape, that is, the side surface shape of the protruding ridge 212 can be a straight surface or an arc surface.

[0048] In some embodiments, a partition structure is provided between the side wall of the atomizing bracket 21 and the airway bracket 22. The partition structure is located between any two adjacent oil guide sections 231. Here, n partition structures are provided, each located between two adjacent oil guide sections 231. The partition structure can isolate the oil on different oil guide sections 231 on the side between the airways, further preventing oil from crossing between oil paths of different types of oil in different oil tanks 11, thereby improving the user experience. The partition structure can be in the form of a sealing gasket or a sealing groove, etc.

[0049] The separating structure includes a protrusion 222 and a recess 213. One of the protrusions 222 and the recess 213 is disposed on the atomizing bracket 21, and the other is disposed on the airway bracket 22. When the airway bracket 22 is installed in the mounting groove 211 of the atomizing bracket 21, the protrusion 222 is precisely embedded in the recess 213, thus achieving a separating function. Moreover, the extending direction of the protrusion 222 and the recess 213 is perpendicular to the circumferential direction of the airway bracket 22, that is, the extending direction of the protrusion 222 and the recess 213 is perpendicular to the arrangement direction of the multiple oil guides 231, resulting in a better separating effect of the separating structure. During installation, the direction in which the airway bracket 22 extends into the mounting groove 211 is consistent with the direction in which the protrusion 222 extends into the recess 213. This allows the protrusion 222 to be smoothly embedded into the recess 213 and provides guidance and limitation for the installation position of the airway bracket 22, which helps to improve the installation reliability and structural strength of the airway bracket 22 and the atomizing bracket 21.

[0050] like Figure 5 , 6 As shown in Figure 10, the protrusion 222 in the partition structure is provided on the side of the airway support 22, and the groove 213 is provided on the side wall of the atomizing support 21. Since the airway support 22 is made of ceramic material, the protrusion 222 is easy to process on the airway support 22 without affecting the structural strength of the airway support 22. Moreover, a limiting part 214 is provided on the bottom wall of the mounting groove 211 of the atomizing support 21. When the airway support 22 is connected to the atomizing support 21, the end of the protrusion 222 on the airway support 22 abuts against the limiting part 214, thereby forming a limit between the airway support 22 and the atomizing support 21, so that the distance between the first end face of the airway support 22 and the bottom wall of the mounting groove 211 of the atomizing support 21 is maintained at a preset value, which is beneficial to improving assembly efficiency and structural stability.

[0051] In some embodiments, two oil tanks 11, two oil guides 231, and two heating elements 24 are provided. The two heating elements 24 are respectively located on opposite sides of the airway support 22, and the two oil guides 231 are respectively located on opposite sides of the airway support 22. During installation, the two heating elements abut against the two sides of the airway support 22, and then an oil guide 23 is provided on the outside of the airway support 22 so that each heating element is sandwiched between the oil guide 231 of the oil guide 23 and the airway support 22. Finally, the airway support 22, the heating elements, and the oil guide 23 are embedded together into the mounting groove 211 of the atomizing support 21. Through the compression deformation of the oil guide 23, the heating elements abut against the side wall of the airway support 22. In this way, the oil in each oil tank 11 of the oil cup 1 can pass through the atomizing support 21, the oil guide 23, the heating elements, and the airway support 22 in sequence, thereby heating and atomizing the oil to form an aerosol.

[0052] Each heating element has a first contact portion and a second contact portion. By connecting the first contact portion and the second contact portion to the positive and negative poles, the heating element can generate heat, causing the heating element to heat and atomize the oil on the oil guide 23 to form an aerosol.

[0053] like Figure 11 , 12 As shown, the base assembly 3 includes a base body 31, a first electrode 33, and a second electrode 34. Both the first electrode 33 and the second electrode 34 are connected to the base body 31, thereby connecting the first electrode 33 and the second electrode 34 to the positive and negative terminals of the battery, respectively, via the base body 31. For example, the base body 31 has electrode holes for inserting the first electrode 33 and the second electrode 34, with a portion of each electrode inserted into the electrode holes. There is one first electrode 33 and two second electrodes 34, meaning the base assembly 3 has three electrodes. The two second electrodes 34 are respectively connected to the second contact portions of two heating elements, connecting the second contact portions of the two heating elements to the positive or negative terminal of the battery. The first electrode 33 has two connecting portions, which are respectively connected to the first contact portions of two heating elements, connecting the first contact portions of the two heating elements to the negative or positive terminal of the battery. Thus, by connecting the two heating elements to the positive and negative terminals of the battery through three electrodes, the space occupied by the electrodes is saved, allowing for layout within a limited internal space, facilitating installation, and not affecting the stability of other structural components. Moreover, the three electrodes can control the two heating elements, enabling three control scenarios: either the oil in the two oil tanks 11 can be used individually, or the oil in the two oil tanks 11 can be used together, thus improving the user experience.

[0054] In the specific design, the first electrode 33 has a conductive first end and two second ends. The first end of the first electrode 33 is inserted into the electrode hole of the base body 31, and the two second ends are electrically connected to the second contact portions of the two heating elements, with two connecting portions formed on the two second ends. Here, the first electrode 33 can be configured as Y-shaped.

[0055] An oil-absorbing component 32 is also provided on the base body 31. The oil-absorbing component 32 is located inside the base body 31. The first electrode 33 and the second electrode 34 both pass through the oil-absorbing component 32. The oil-absorbing component 32 can play a role in preventing oil leakage.
