Description

Technical Field

[0001] The present invention relates to the technical field of electronic atomization, and particularly to an atomization mechanism and an electronic atomization device. Background Art

[0002] An electronic atomization device, namely an electronic cigarette, has the same appearance as a cigarette, a similar taste to a cigarette, and even has many more flavors than ordinary cigarettes. It can also draw out smoke, taste and feeling like a cigarette. It is mainly used for quitting smoking and replacing cigarettes. An electronic cigarette is a non-combustible alternative cigarette product. It has some characteristics similar to ordinary cigarettes, can refresh the mind, satisfy the pleasure of smokers and the usage habits developed over the years. However, it is essentially different from ordinary cigarettes. Electronic cigarettes do not burn, do not contain tar, and do not contain more than 460 chemical substances produced during the combustion of ordinary cigarettes that can cause respiratory and cardiovascular diseases. Thus, the carcinogenic substances in ordinary cigarettes are removed, and it will not cause harm to others from "second-hand smoke" or pollute the environment. The key component of a traditional electronic cigarette is an electronic atomizer. The air intake base in the electronic atomizer is used in combination with an oil cup to facilitate the installation and sealing of the atomization components.

[0003] However, in order to improve the sealing performance, a silicone rubber sealing ring is usually added to the air intake base, which makes the overall diameter of the air intake base larger, and it is difficult to press the silicone rubber sealing ring during installation. Moreover, adding a silicone rubber sealing ring increases the number of components of the electronic atomization device and makes the assembly process of the electronic atomization device more complicated.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0031] The present invention relates to an atomization mechanism. In one embodiment, the atomization mechanism includes an atomization component and a sealing component. The atomization component includes an atomization central tube, an atomization seat and an atomization heating element. The atomization central tube is connected to the atomization seat, and an air outlet channel is formed inside the atomization central tube and the atomization seat. The atomization heating element is disposed in the air outlet channel. The sealing component includes an interference-fitted sealing oil cup and a plastic base. The plastic base is connected to the atomization seat, and both the plastic base and the atomization seat are sleeved inside the sealing oil cup. The additional sealing ring provided on the plastic base is omitted, and the tight connection between the plastic base and the sealing oil cup can be achieved directly through the interference fit between the plastic base and the inner wall of the sealing oil cup. While ensuring the sealing performance between the plastic base and the sealing oil cup, the use of additional sealing rings is avoided, which has the characteristics of simplifying the assembly and effectively reducing the production cost of the atomization mechanism.

[0032] Please refer to Figure 1 and Figure 2 , which is a schematic structural diagram of the atomization mechanism according to an embodiment of the present invention.

[0033] The atomization mechanism 10 of one embodiment includes an atomization component 100 and a sealing component 200. The atomization component 100 includes an atomization central tube 110, an atomization base 120, and an atomization heating element 130. The atomization central tube 110 is connected to the atomization base 120, and an air outlet channel 102 is formed inside the atomization central tube 110 and the atomization base 120. The atomization heating element 130 is disposed in the air outlet channel 102. The sealing component 200 includes an interference-fitted sealing oil cup 210 and a plastic base 220. The plastic base 220 is connected to the atomization base 120, and both the plastic base 220 and the atomization base 120 are sleeved inside the sealing oil cup 210.

[0034] In this embodiment, the additional sealing ring on the plastic base 220 is omitted. The tight connection between the plastic base 220 and the sealing oil cup 210 can be directly achieved through the interference fit between the plastic base 220 and the inner wall of the sealing oil cup 210. Without using an extra sealing ring while ensuring the sealing performance between the plastic base 220 and the sealing oil cup 210, it has the characteristic of simplified assembly and effectively reduces the production cost of the atomization mechanism. Moreover, along the air outlet direction of the air outlet channel 102, the distance between the first arc-shaped inclined surface 222 and the inner wall of the sealing oil cup 210 gradually increases. Also, the material of the plastic base is plastic. In this embodiment, a silicone base with a silicone ring is used, and the anti-oil leakage level of the atomization mechanism is IP56 to IP58 and IP66 to IP68. While using the plastic base in this application, the anti-oil leakage level of the atomization mechanism is IP57 to IP58 and IP67 to IP68, achieving the same anti-oil leakage effect as the original silicone base with a silicone ring.

[0035] In one embodiment, the plastic base 220 has a first arc-shaped inclined surface 222. The first arc-shaped inclined surface 222 inclines away from the inner wall of the sealing oil cup 210, and the first arc-shaped inclined surface 222 is used for sliding contact with the inner wall of the sealing oil cup 210 when the plastic base 220 is pressed into the sealing oil cup 210. In this embodiment, a sloped first arc-shaped inclined surface 222 is formed at the position where the plastic base 220 contacts the sealing oil cup 210. When installing the plastic base 220 into the sealing oil cup 210, the plastic base 220 can be quickly guided into the sealing oil cup 210 by means of the inclination angle of the first arc-shaped inclined surface 222, facilitating the installation of the plastic base 220 and the sealing oil cup 210.

[0036] In one embodiment, please refer to Figure 2 and Figure 3, the atomizing base 120 has a second arc-shaped inclined surface 122, the second arc-shaped inclined surface 122 is inclined away from the inner wall of the sealing oil cup 210, and the second arc-shaped inclined surface 122 is used for slidingly abutting against the inner wall of the sealing oil cup 210. In this embodiment, the second arc-shaped inclined surface 122 is located at the position where the atomizing base 120 contacts the sealing oil cup 210. The second arc-shaped inclined surface 122 has a guiding function, that is, by means of the slope of the second arc-shaped inclined surface 122, the second arc-shaped inclined surface 122 is inclined away from the inner wall of the sealing oil cup 210, so that in the air outlet direction along the air outlet channel 102, the distance between the second arc-shaped inclined surface 122 and the inner wall of the sealing oil cup 210 gradually increases, so that the end of the atomizing base 120 forms an isosceles trapezoid structure. When the atomizing base 120 is pressed into the sealing oil cup 210, the second arc-shaped inclined surface 122 smoothly guides the atomizing base 120 into the sealing oil cup 210, improving the installation convenience between the atomizing base 120 and the sealing oil cup 210.

[0037] In another embodiment, the atomizing base 120 is in interference connection with the inner wall of the sealing oil cup 210, that is, the projected area of the second arc-shaped inclined surface 122 on the inner wall of the sealing oil cup 210 is smaller than the projected area of the atomizing base 120 on the inner wall of the sealing oil cup 210, that is, the inclined part of the second arc-shaped inclined surface 122 is a part of the atomizing base 120, so that the diameter of the part of the atomizing base 120 outside the second arc-shaped inclined surface 122 is larger than the caliber of the sealing oil cup 210. In this way, after the second arc-shaped inclined surface 122 is located in the sealing oil cup 210, the remaining part of the atomizing base 120 will have an interference fit with the sealing oil cup 210 after being pressed into the sealing oil cup 210, so that the atomizing base 120 is in close contact with the inner wall of the sealing oil cup 210, improving the sealing performance between the atomizing base 120 and the sealing oil cup 210.

[0038] In one of the embodiments, please refer to Figure 3, the atomizing central tube 110, the atomizing base 120 and the sealing oil cup 210 form an oil storage cavity 104. The oil storage cavity 104 is communicated with the oil guiding hole of the atomizing central tube 110. The atomizing base 120 is provided with an oil injection hole 124 communicated with the oil storage cavity 104. A part of the plastic base 220 is located in the oil injection hole 124 to block the oil injection hole 124. In this embodiment, the oil storage cavity 104 is used to accommodate e-liquid. The oil storage cavity 104 is also communicated with the oil guiding hole and the oil injection hole 124 respectively. The oil guiding hole is opened on the atomizing central tube 110, which is convenient for guiding the e-liquid in the oil storage cavity 104 into the atomizing heating element 130, so as to facilitate the atomizing heating element 130 to heat and atomize the e-liquid. The oil injection hole 124 is opened on the atomizing base 120. The oil injection hole 124 is used to inject e-liquid into the oil storage cavity 104. After the oil injection is completed, a part of the plastic base 220 is clamped in the oil injection hole 124. The plastic base 220 seals the oil injection hole 124, which is convenient for storing the e-liquid in the oil storage cavity 104 and reduces the probability of the e-liquid leaking through the oil injection hole 124.

[0039] Further, please refer to Figure 3 , the plastic base 220 includes a plastic body 224 and a sealing glue column 226 which are connected to each other. The plastic body 224 is in interference connection with the inner wall of the sealing oil cup 210. The sealing glue column 226 passes through the oil injection hole 124, and the sealing glue column 226 is in interference connection with the inner wall of the oil injection hole 124. In this embodiment, the sealing glue column 226 is located on the side of the plastic body 224 close to the atomizing base 120. The sealing glue column 226 passes through the oil injection hole 124, and the sealing glue column 226 is in interference connection with the inner wall of the oil injection hole 124 to improve the connection strength between the sealing glue column 226 and the inner wall of the oil injection hole 124, so as to improve the sealing performance between the sealing glue column 226 and the atomizing base 120. The plastic body 224 is sleeved in the sealing oil cup 210, and the plastic body 224 is in interference connection with the inner wall of the sealing oil cup 210 to improve the connection strength between the plastic body 224 and the inner wall of the sealing oil cup 210, so as to improve the sealing performance between the plastic body 224 and the sealing oil cup 210.

[0040] In one embodiment, please refer to Figure 4, the sealing assembly 200 further includes an electrode post 230. The plastic base 220 is provided with a pole hole 228 communicating with the air outlet channel 102. The electrode post 230 is inserted into the pole hole 228 and connected to the atomizing heating element 130. The electrode post 230 is used to connect to an external power supply. In this embodiment, the pole hole 228 is used for inserting the electrode post 230. After the electrode post 230 passes through the pole hole 228, it abuts against the atomizing heating element 130. The electrode post 230 holds the atomizing heating element 130 against the atomizing base 120, that is, the atomizing base 120 and the electrode post 230 jointly clamp one end of the atomizing heating element 130. After ensuring the electrical connection between the electrode post 230 and the atomizing heating element 130, the atomizing heating element 130 is stably fixed on the atomizing base 120, improving the stability of the atomizing heating element 130 on the atomizing base 120.

[0041] Further, please refer to Figure 4 , the plastic base 220 is further provided with an installation groove 221 communicating with the pole hole 228. A part of the electrode post 230 is clamped in the installation groove 221. In this embodiment, the installation groove 221 is formed on the plastic base 220. The installation groove 221 also communicates with the pole hole 228. The opening of the installation groove 221 faces outside the sealing oil cup 210. When the electrode post 230 is inserted into the pole hole 228, the end of the electrode post 230 away from the atomizing base 120 is clamped in the installation groove 221, so that the electrode post 230 is stably installed on the plastic base 220, improving the connection stability between the electrode post 230 and the plastic base 220.

[0042] In one embodiment, please refer to Figure 5 , the atomizing assembly 100 further includes a limiting tube 140. A part of the limiting tube 140 is located inside the atomizing central tube 110. The inner part of the limiting tube 140 communicates with the air outlet hole of the sealing oil cup 210 and the atomizing central tube 110 respectively. The limiting tube 140 is connected to the sealing oil cup 210 and the atomizing heating element 130 respectively. In this embodiment, a part of the limiting tube 140 is clamped in the atomizing central tube 110. One end of the limiting tube 140 abuts against the atomizing heating element 130, and the other end of the limiting tube 140 abuts against the sealing oil cup 210. The part of the limiting tube 140 extending into the atomizing central tube 110 blocks the atomizing central tube 110 to prevent the atomizing central tube 110 from extending excessively, ensuring that the oil guiding hole of the atomizing heating element 130 is correspondingly arranged with the atomizing central tube 110, so as to facilitate guiding the e-liquid to the atomizing heating element 130.

[0043] Further, please refer to Figure 5 The limiting tube 140 includes a tube body 142 and a blocking portion 144 which are connected to each other. The tube body 142 is located inside the atomization central tube 110 and abuts against the atomization heating element 130. The blocking portion 144 abuts against one end of the atomization central tube 110 away from the atomization base 120. At least one of the blocking portion 144 and the tube body 142 also abuts against the air outlet pipe of the sealed oil cup 210. In this embodiment, the tube body 142 is communicated with the air outlet channel 102, which is convenient for guiding the smoke generated from the atomization heating element 130 to the air outlet hole of the sealed oil cup 210. The blocking portion 144 is located at one end of the tube body 142 away from the atomization base 120, that is, the blocking portion 144 abuts against one end of the atomization central tube 110 away from the atomization base 120, so that the blocking portion 144 is located outside the atomization central tube 110, thereby preventing the limiting tube 140 from extending excessively into the atomization central tube 110.

[0044] In one embodiment, please refer to Figure 6 and Figure 7 together. The atomization heating element 130 includes an atomization core 132 and a heating element 134 which are connected to each other. The atomization central tube 110 is provided with a cotton clamping groove 112. The cotton clamping groove 112 is located at a position of the atomization central tube 110 close to the atomization base 120, and the cotton clamping groove 112 is communicated with the air outlet channel 102. The atomization core 132 is respectively disposed in the air outlet channel 102 and the cotton clamping groove 112. The heating element 134 is used for connecting to an external power supply.

[0045] In this embodiment, during assembly, only need to first press the atomization core 132 into the atomization central tube 110 from the end with the cotton clamping groove 112. After the atomization core 132 is stuck in the cotton clamping groove 112, then fix the atomization central tube 110 with the atomization core 132 on the atomization base 120 to realize the rapid installation of the atomization core 132 assembly 130 and the atomization assembly 100. Moreover, since a part of the atomization core 132 is clamped in the cotton clamping groove 112, the atomization core 132 is stably installed between the atomization base 120 and the atomization central tube 110, improving the installation stability of the atomization core 132 on the atomization mechanism.

[0046] In one embodiment, please refer to Figure 6 and Figure 7, the atomization core 132 includes a cotton core body 1322 and a limiting part 1324 which are connected to each other. The cotton core body 1322 is located inside the atomization center tube 110, and the limiting part 1324 passes through the cotton clamping groove 112. The limiting part 1324 is used to abut against the atomization center tube 110. In this embodiment, the cotton core body 1322 is directly connected to the heating element 134. After the heating element 134 is powered on, the heat generated on the heating element 134 will be directly conducted to the cotton core body 1322 to heat the e-liquid on the cotton core body 1322. The limiting part 1324 is connected to the cotton core body 1322. The limiting part 1324 is a part of the cotton core body 1322, that is, the limiting part 1324 is the part of the cotton core body 1322 protruding from the air outlet channel 102. Moreover, a part of the limiting part 1324 is located inside the cotton clamping groove 112, so that when the atomization core 132 is pressed into the atomization center tube 110, the limiting part 1324 is blocked by the bottom of the cotton clamping groove 112. When the atomization core 132 is clamped on the atomization center tube 110, it is convenient and at the same time avoids the situation that the atomization core 132 extends excessively into the atomization center tube 110, ensuring that the atomization core 132 is located at a designated position when pressed into the atomization center tube 110. In another embodiment, the cotton core body 1322 and the limiting part 1324 are integrally formed, which is convenient for forming the atomization core 132 at one time, thereby improving the overall strength of the atomization core 132.

[0047] Further, please refer to Figure 7, a connection groove 126 communicating with the air outlet channel 102 is formed in the atomizing base 120. A part of the atomizing central tube 110 is located in the connection groove 126, and one side of the limiting portion 1324 away from the cotton core body 1322 abuts against the inner wall of the connection groove 126. In this embodiment, the connection groove 126 is formed in the atomizing base 120, and the opening of the connection groove 126 faces the atomizing central tube 110. During assembly, the atomizing central tube 110 with the atomizing core 132 clamped thereon moves towards the atomizing base 120. Finally, a part of the atomizing central tube 110 is embedded in the connection groove 126, so that the atomizing central tube 110 is clamped with the atomizing base 120, facilitating clamping the atomizing central tube 110 on the atomizing base 120. In addition, since the atomizing core 132 is also clamped on the atomizing central tube 110, a part of the limiting portion 1324 of the atomizing core 132 is also clamped in the connection groove 126 together with the atomizing central tube 110, so that the atomizing core 132 is also stably clamped in the connection groove 126, thereby improving the installation stability of the atomizing core 132 on the atomizing base 120. In another embodiment, the limiting portion 1324 is connected with the atomizing base 120 by interference fit. The limiting portion 1324 extends excessively into the connection groove 126, so that a certain reverse elastic force is generated on the atomizing base 120 and the atomizing central tube 110, thereby making the connection between the atomizing base 120 and the atomizing central tube 110 more firm and further improving the connection stability between the atomizing base 120 and the atomizing central tube 110.

[0048] Furthermore, please refer to Figure 6, the limiting part 1324 has an introduction inclined surface 1326, and the introduction inclined surface 1326 is located on the side of the limiting part 1324 away from the cotton core body 1322. In the air outlet direction of the air outlet channel 102, the distance between the introduction inclined surface 1326 and the atomization center tube 110 gradually increases. In this embodiment, the limiting part 1324 serves as an extension part of the atomization core 132, that is, the limiting part 1324 is the part where the cotton core body 1322 protrudes out of the air outlet channel 102. The limiting part 1324 not only avoids the situation where the atomization core 132 is excessively embedded, but also can realize the rapid installation of the atomization core 132 on the atomization center tube 110 through the cooperation with the cotton clamping groove 112. And the introduction inclined surface 1326 is formed on the limiting part 1324, and in the air outlet direction of the air outlet channel 102, the distance between the introduction inclined surface 1326 and the atomization center tube 110 gradually increases, so that the limiting part 1324 forms a wedge-shaped structure, that is, the volume of the part of the limiting part 1324 close to the atomization seat 120 is smaller than the volume of the part far from the atomization seat 120. In this way, when the atomization core 132 is buckled in the connection groove 126 of the atomization seat 120 following the atomization center tube 110, under the inclined guidance of the introduction inclined surface 1326, the length of the limiting part 1324 embedded in the connection groove 126 increases, which is convenient for the limiting part 1324 to be embedded in the connection groove 126, and at the same time, it also makes the limiting part 1324 match with the atomization seat 120, that is, while facilitating the embedding of the limiting part 1324 into the connection groove 126, the atomization core 132 and the atomization center tube 110 can be stably clamped on the atomization seat 120.

[0049] In one embodiment, please refer to Figure 8, the atomizing central tube 110 is provided with an oil guiding hole 112 which communicates with the air outlet channel 102, and the oil guiding hole 112 is used to guide the e-liquid to the atomizing core 132. In this embodiment, the atomizing central tube 110 is used to form an oil storage chamber between the atomizing base 120 and the oil cup so as to store the e-liquid therein. The atomizing core 132 is clamped in the cotton clamping groove 112 of the atomizing central tube 110. The cotton clamping groove 112 is a notch of the atomizing central tube 110. Besides serving as a clamping interface of the atomizing core 132, it also serves as an oil inlet of the atomizing central tube 110, that is, the cotton clamping groove 112 can also guide the e-liquid onto the cotton core body 1322 in the atomizing central tube 110. The oil guiding hole 112, as a separate oil inlet on the atomizing central tube 110, and the cotton clamping groove 112 are jointly used to introduce the e-liquid into the atomizing central tube 110, so that the oil guiding rate of the atomizing central tube 110 is increased, and thus the rate of the atomizing core 132 being wetted by the e-liquid is increased. In another embodiment, the oil guiding hole 112 and the cotton clamping groove 112 are symmetrically arranged. The oil guiding hole 112 and the cotton clamping groove 112 are both used to introduce the e-liquid into the atomizing central tube 110. Setting the oil guiding hole 112 and the cotton clamping groove 112 symmetrically avoids the position of the e-liquid introduced into the atomizing central tube 110 being too concentrated, so that the e-liquid wets the cotton core body 1322 in the atomizing central tube 110 from different directions, thereby increasing the diffusion rate of the e-liquid on the atomizing core 132.

[0050] In one embodiment, please refer to Figure 7 , the atomizing base 120 is provided with an air guiding hole 128 that communicates with the air outlet channel 102. The heating element 134 passes through the air guiding hole 128, and one end of the heating element 134 away from the atomizing core 132 is used to connect with the electrode post. In this embodiment, the air guiding hole 128 communicates with the external environment. The air guiding hole 128 is used to introduce external air into the air outlet channel 102 so as to take out the atomized smoke together. Wherein, part of the heating element 134 and part of the atomizing core 132 are located in the air outlet channel 102. The heating element 134 heats the e-liquid on the atomizing core 132, and the heating element 134 generates heat after being conducted to an external power supply. With the arrangement of the air guiding hole 128, it is convenient to lead out part of the heating element 134 and make it close to the external power supply, so as to facilitate the electrical connection between the heating element 134 and the external power supply.

[0051] Further, please refer to Figure 7, the atomization base 120 is further provided with a wire clamping hole 121, the opening of the wire clamping hole 121 faces away from the atomization central tube 110, a part of the heating element 134 is received in the wire clamping hole 121, and the wire clamping hole 121 is further used to receive a part of the electrode post, so that the electrode post and the inner wall of the wire clamping hole 121 clamp the part of the heating element 134 located in the wire clamping hole 121. In this embodiment, the wire clamping hole 121 corresponds to the electrode post, and the wire clamping hole 121 receives a part of the electrode post therein. Moreover, after the atomization core 132 is fastened to the atomization base 120 along with the atomization central tube 110, a part of the heating element 134 passes through the air guide hole 128, and then passes through the inside of the atomization base 120 and is received in the wire clamping hole 121. The opening of the wire clamping hole 121 faces away from the atomization central tube 110, that is, the opening of the wire clamping hole 121 faces the electrode post, which is convenient for clamping a part of the heating element 134 between the electrode post and the inner wall of the wire clamping hole 121 when connecting the base with the electrode post to the atomization base 120, thereby facilitating the quick installation and fixation between the heating element 134 and the electrode post, and improving the installation stability of the heating element 134 on the atomization base 120.

[0052] In each of the above embodiments, the heating element is a heating resistance wire, which is used for electrically connecting with an external battery rod and heating the atomization core after being powered on. Please refer to Figure 9 , the atomization core 132 includes multiple layers of cotton wraps 1328, that is, the multiple layers of cotton wraps 1328 are stacked on top of each other. Two pins of the heating element are located between any two adjacent cotton wraps, and the multiple layers of cotton wraps 1328 are bent to fix the heating element thereon.

[0053] In one of the embodiments, the present application further provides an electronic atomization device, including the atomization mechanism described in any of the above embodiments. In this embodiment, the atomization mechanism includes an atomization component and a sealing component. The atomization component includes an atomization central tube, an atomization base, and an atomization heating element. The atomization central tube is connected to the atomization base, and an air outlet channel is formed inside the atomization central tube and the atomization base. The atomization heating element is disposed in the air outlet channel. The sealing component includes an interference-connected sealing oil cup and a plastic base. The plastic base is connected to the atomization base, and both the plastic base and the atomization base are sleeved inside the sealing oil cup. The plastic base has a first arc-shaped inclined surface. The first arc-shaped inclined surface inclines away from the inner wall of the sealing oil cup, and the first arc-shaped inclined surface is used for slidingly abutting against the inner wall of the sealing oil cup when the plastic base is pressed into the sealing oil cup. Compared with the prior art, the present invention has at least the following advantages: 1. A first arc-shaped inclined surface with a slope is formed at the position where the plastic base contacts the sealing oil cup. When installing the plastic base into the sealing oil cup, the plastic base can be quickly guided into the sealing oil cup by means of the inclination angle of the first arc-shaped inclined surface, facilitating the installation of the plastic base and the sealing oil cup; 2. The additional sealing ring provided on the plastic base is omitted. The tight connection between the plastic base and the sealing oil cup can be realized directly through the interference fit between the plastic base and the inner wall of the sealing oil cup. Without using an additional sealing ring while ensuring the sealing performance between the plastic base and the sealing oil cup, the production cost of the atomization mechanism is effectively reduced.

[0054] The above-described embodiments merely illustrate several implementation manners of the present invention, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
