Description

Technical Field

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

[0002] Electronic atomizing devices can atomize e-liquid and other aerosol-generating substrates, thus forming aromatic aerosols, making them popular among users. However, traditional electronic atomizing devices often suffer from aerosol-generating substrate leakage. This leakage can corrode the internal circuitry of the device and allow users to inhale the aerosol-generating substrate during vaping. Utility Model Content

[0003] One of the technical problems addressed by this application is how to improve the leak-proof performance of electronic atomization devices.

[0004] An electronic atomizing device, comprising:

[0005] The shell assembly has a liquid storage chamber for storing the liquid atomizing matrix;

[0006] A support member surrounds the atomizing chamber and is connected to the shell assembly. The support member has a liquid guiding channel that connects the atomizing chamber and the liquid storage chamber.

[0007] An atomizing core, located within the atomizing chamber and made of a solid porous material with capillary action, has an atomizing channel. The atomizing core is used to heat the atomizing matrix to generate an aerosol, which is then output from the atomizing channel.

[0008] The buffer mechanism includes a first buffer and a second buffer that are capable of buffering the atomizing matrix and are located on opposite sides of the liquid guiding channel. The first buffer is located in the liquid storage chamber, and the second buffer is located in the atomizing chamber and sleeved around the atomizing core. The atomizing matrix enters the atomizing core through the first buffer, the liquid guiding channel and the second buffer.

[0009] In one embodiment, the atomizing core is a cylindrical porous ceramic core.

[0010] In one embodiment, the first buffer is sleeved outside the support, and the second buffer is sleeved inside the support, with the first buffer and the second buffer respectively blocking the opposite ends of the liquid guiding channel;

[0011] The first buffer is a liquid storage device made of porous material, and the second buffer is a liquid guiding device made of porous material, wherein the pore diameter of the liquid storage device is smaller than the pore diameter of the liquid guiding device.

[0012] In one embodiment, the wall thickness of the first buffer is greater than or equal to the wall thickness of the second buffer;

[0013] And / or, the number of liquid guiding channels is multiple, and the multiple liquid guiding channels are arranged at intervals along the circumference of the support.

[0014] In one embodiment, the support member includes a support ring, a first sleeve, and a second sleeve. The first sleeve and the second sleeve protrude from opposite sides in the thickness direction of the support ring. The first sleeve is connected to the outer edge of the support ring, and the second sleeve is connected to the inner edge of the support ring. The second sleeve forms the atomizing cavity and is sleeved between the first buffer member and the second buffer member. The first buffer member abuts against the support ring.

[0015] In one embodiment, the system further includes a seal for sealing the liquid storage chamber, the support ring being in sealing contact with the seal, the shell assembly including a cannula located within the liquid storage chamber, the cannula forming an air intake channel communicating with the outside and the atomizing chamber, and the seal being sleeved between the first sleeve and the cannula.

[0016] In one embodiment, the seal includes a sealing body, a lug, and a protruding ring. The lug protrudes from the outer side of the sealing body, the first sleeve is fitted over the sealing body and seals against the lug, the support ring seals against the sealing body, and the protruding ring protrudes from the inner side of the sealing body and is fitted over the insertion tube.

[0017] In one embodiment, the shell assembly includes an outer shell and a base, the base being located inside the outer shell and forming the liquid storage cavity with the outer shell, the base having an air inlet and a mounting hole, the air inlet communicating with the atomizing cavity, the bottom wall of the mounting hole having a first stepped surface surrounding the air inlet, the support member being interference-fitted with the mounting hole and abutting against the first stepped surface.

[0018] In one embodiment, the base is further provided with a receiving hole, the liquid storage chamber is connected to the receiving hole, the mounting hole is connected between the receiving hole and the air inlet, the support member, the atomizing core and the buffer mechanism are all located in the receiving hole, and a second stepped surface is formed on the bottom wall surface of the receiving hole surrounding the mounting hole, and the first buffer member abuts against the second stepped surface.

[0019] In one embodiment, the receiving orifice includes a constricted section that is in direct communication with the liquid storage cavity, and the diameter of the constricted section decreases from one end of the constricted section near the liquid storage cavity to the other end away from the liquid storage cavity.

[0020] One technical effect of an embodiment of this application is that, since the atomizing matrix in the liquid storage chamber enters the atomizing core sequentially through the first buffer, the liquid guiding channel, and the second buffer, the combined action of the first and second buffers makes the supply speed of the atomizing matrix to the atomizing core more stable, thereby effectively preventing leakage caused by excessive supply speed of the atomizing matrix from overflowing from the surface of the atomizing core. Simultaneously, the atomizing core itself is made of a solid porous material with capillary action, possessing smaller pore sizes and more stable atomizing matrix conduction speed compared to traditional heating mesh cores, further improving the leak-proof performance of the electronic atomizing device. This improved leak-proof performance prevents leaked atomizing matrix from corroding the battery or other circuit structures of the electronic atomizing device, thus extending its lifespan. Furthermore, it prevents leaked atomizing matrix from being inhaled into the user's mouth under the user's suction force, thereby improving the user's vaping experience. Attached Figure Description

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0034] See Figure 1 , Figure 2 and Figure 3This application provides an electronic atomizing device 10 for atomizing an atomizing matrix, thereby forming an aerosol that can be inhaled by a user. The atomizing matrix can be e-liquid, etc. The electronic atomizing device 10 includes a shell assembly 100, a support member 200, an atomizing core 300, and a buffer mechanism 400. The shell assembly 100 forms a liquid storage chamber 111 for storing the atomizing matrix. The support member 200 forms an atomizing chamber 2321 and is connected to the shell assembly 100. The support member 200 has a liquid guiding channel 2322 that can simultaneously connect the atomizing chamber 2321 and the liquid storage chamber 111. The atomizing core 300 is located inside the atomizing chamber 2321 and can generate heat to heat and atomize the atomizing matrix. The aerosol formed by heating and atomizing the atomizing matrix is ​​discharged into the atomizing chamber 2321. The atomizer core 300 is made of a porous material, giving it a certain porosity. This allows the micropores within the core to create capillary action, enabling the core to buffer and transport the atomization matrix. For example, the core can be made of porous ceramic materials, and may be a cylindrical porous ceramic core. It's understandable that when the core is a porous ceramic core, compared to a conventional heating mesh core, the pore size is smaller and more uniform, reducing leakage. Furthermore, the atomized aerosol produced by the core 300 has a more delicate and richer flavor.

[0035] The buffer mechanism 400 includes a first buffer 410 and a second buffer 420. The first buffer 410 is located in the liquid storage chamber 111, and the second buffer 420 is located in the atomization chamber 2321, such that the first buffer 410 and the second buffer 420 are located on opposite sides of the liquid guiding channel 2322. The atomizing substrate in the liquid storage chamber 111 can sequentially enter the atomizing core 300 through the first buffer 410, the liquid guiding channel 2322, and the second buffer 420, thereby realizing the atomization of the atomizing substrate by the atomizing core 300. If the atomizing matrix is ​​supplied directly to the atomizing core 300 through the liquid channel 2322, the supply speed of the atomizing matrix to the atomizing core 300 will be unstable. If the supply speed is too high, the atomizing matrix will overflow from the surface of the atomizing core 300, causing leakage. This leaked atomizing matrix will corrode the battery or other circuitry of the electronic atomizing device 10, thus affecting its lifespan. Furthermore, the leaked atomizing matrix can be inhaled into the user's mouth under the user's suction force, thus affecting the user's vaping experience.

[0036] See Figure 1 , Figure 2 and Figure 3Regarding the electronic atomizing device 10 in the above embodiments, since the atomizing matrix in the liquid storage chamber 111 can sequentially enter the atomizing core 300 through the first buffer 410, the liquid guiding channel 2322, and the second buffer 420, the combined action of the first buffer 410 and the second buffer 420 will make the supply speed of the atomizing matrix to the atomizing core 300 more stable, thereby effectively preventing the atomizing matrix from overflowing from the surface of the atomizing core 300 due to excessive supply speed and thus causing leakage. Simultaneously, considering that the atomizing core 300 itself is made of a solid porous material with capillary action, possessing smaller pore sizes and more stable atomizing matrix conduction speed compared to traditional heating mesh cores, the leak-proof performance of the electronic atomizing device 10 can be further improved. Given the improved leak-proof performance, on the one hand, leaked atomizing matrix can be prevented from corroding the battery or other circuit structures of the electronic atomizing device 10, thereby increasing the service life of the electronic atomizing device 10. On the other hand, leaked atomizing matrix is ​​prevented from being inhaled into the user's mouth under the user's suction force, thereby improving the user's vaping experience.

[0037] See Figure 1 , Figure 2 and Figure 3 In some embodiments, the first buffer 410 is fitted outside the support 200, and the second buffer 420 is fitted inside the support 200. Both the first buffer 410 and the second buffer can be hollow cylindrical structures, such as cylindrical or prismatic shapes. The first buffer 410 and the second buffer 420 respectively block the opposite ends of the liquid guiding channel 2322. This allows the atomizing matrix in the first buffer 410 to be smoothly transferred to the second buffer 420 through the liquid guiding channel 2322, and also makes the electronic atomizing device 10 more compact and simple in structure.

[0038] See Figure 1 , Figure 2 and Figure 3 In some embodiments, the second buffer 420 is sleeved around the periphery of the atomizing core 300. This results in a larger contact area between the second buffer 420 and the atomizing core 300, ensuring that the second buffer 420 supplies liquid to the atomizing core 300 at various positions along its circumference, thus improving the uniformity of liquid supply to the atomizing core 300. Of course, in other embodiments, the second buffer 420 can also be stacked on the atomizing core 300.

[0039] See Figure 3 , Figure 4 and Figure 5In some embodiments, the wall thickness of the first buffer 410 is greater than or equal to the wall thickness of the second buffer 420. This allows the thicker first buffer 410 to store and buffer a larger amount of atomizing matrix absorbed within the liquid chamber 111, while the thinner second buffer 420 can increase the transmission speed of the atomizing matrix. This ensures that a sufficient amount of atomizing matrix is ​​transmitted from the first buffer 410 to the atomizing core 300 at a reasonable speed, avoiding defects such as insufficient or excessive supply of atomizing matrix to the atomizing core 300. The first buffer 410 can be a liquid storage component made of porous material, and the second buffer 420 can be a liquid guiding component made of porous material. The pore size of the liquid storage component is smaller than the pore size of the liquid guiding component, that is, the pore size of the first buffer 410 is smaller than the pore size of the second buffer 420. This allows the first buffer 410 with a smaller aperture to have a stronger buffering function for the atomizing matrix, meaning that the first buffer 410 per unit volume can store more atomizing matrix; and the second buffer 420 with a larger aperture can reduce the transmission resistance of the atomizing matrix, thereby increasing the transmission speed of the atomizing matrix in the second buffer 420 and ensuring that the atomizing matrix is ​​quickly transmitted to the atomizing core 300.

[0040] See Figure 3 , Figure 4 and Figure 5 In some embodiments, the first buffer 410 and the second buffer 420 can be made of the same or different materials. For example, both the first buffer 410 and the second buffer 420 can be made of cotton material, thus enabling the first buffer 410 and the second buffer 420 to effectively buffer and transport the atomized matrix. Multiple liquid guiding channels 2322 are provided, spaced apart circumferentially along the support 200. This allows the first buffer 410 to transport the atomized matrix to the second buffer 420 at multiple different positions circumferentially along the support 200, thereby improving the uniformity of the atomized matrix supply.

[0041] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the shell assembly 100 includes a shell 110, a cannula 120, and a base 130. The base 130 is disposed within the shell 110, and the base 130 and the shell 110 together form a liquid storage chamber 111. The cannula 120 is located within the liquid storage chamber 111, with one end of the cannula 120 fixedly connected to the shell 110. When the shell assembly 100 exists alone, the other end of the cannula 120 is a free end. An air intake channel 121 is provided within the cannula 120, which connects to the outside and the atomizing chamber 2321. The user can perform suction at the end of the air intake channel 121 that connects to the outside, thereby allowing the aerosol in the atomizing chamber 2321 to be absorbed by the user through the air intake channel 121.

[0042] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the atomizing core 300 has an atomizing channel 310 that extends through the atomizing core 300 along its axial direction. Both ends of the atomizing channel 310 are connected to the atomizing chamber 2321. Therefore, the atomizing core 300 can also be a hollow cylindrical structure. By providing the atomizing channel 310, the aerosol in the atomizing chamber 2321 can easily enter the inhalation channel 121 through the atomizing channel 310.

[0043] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the base 130 has an air inlet 131, a mounting hole 132, and a receiving hole 133. The mounting hole 132 connects the air inlet 131 and the receiving hole 133. The air inlet 131 is further away from the suction channel 121 than the mounting hole 132, and the air inlet 131 can connect to the outside. When the user inhales, outside gas enters the atomization chamber 2321 through the air inlet 131, so that the gas carrying the aerosol in the atomization chamber 2321 is absorbed by the user through the suction channel 121. The air inlet 131 and the mounting hole 132 can form a stepped hole. The diameter of the mounting hole 132 is larger than the diameter of the air inlet 131. The air inlet 131 can be formed by a recess in the bottom wall surface of the mounting hole 132. The unrecessed portion of the bottom wall surface forms a first stepped surface 1321 surrounding the air inlet 131. The first stepped surface 1321 is horizontally positioned. During the installation of the support member 200, the support member 200 can be inserted into the mounting hole 132, so that the support member 200 and the mounting hole 132 are interference-fitted, thus realizing the interference connection between the support member 200 and the base 130. Furthermore, the support member 200 abuts against the first step surface 1321 along its axial direction, so that the first step surface 1321 limits the position of the support member 200, thereby improving the assembly accuracy and efficiency of the support member 200.

[0044] See Figure 2 , Figure 3 and Figure 4The liquid storage chamber 111 connects to the receiving hole 133. The receiving hole 133 and the mounting hole 132 can form a stepped hole, with the diameter of the receiving hole 133 being larger than the diameter of the mounting hole 132. The mounting hole 132 can be formed by a recess in the bottom wall surface of the receiving hole 133, and the non-recessed portion of the bottom wall surface forms a second stepped surface 1331 surrounding the mounting hole 132, which is horizontally positioned. The support member 200 can pass through the receiving hole 133. Obviously, the first stepped surface 1321 and the second stepped surface 1331 are spaced apart along the axial direction of the support member 200. The first buffer member 410 is located in the receiving hole 133, such that the first buffer member 410 abuts against the second stepped surface 1331, thereby limiting the first buffer member 410 and improving the assembly accuracy and efficiency of the first buffer member 410. The receiving orifice 133 includes a constriction section 1332 that is directly connected to the liquid storage chamber 111. The diameter of the constriction section 1332 decreases from one end near the liquid storage chamber 111 to the other end away from it, i.e., from the upper end to the lower end. This allows the constriction section 1332 to effectively guide and converge the liquid from the liquid storage chamber 111, ensuring that the liquid in the liquid storage chamber 111 flows into the first buffer 410 at a reasonable speed.

[0045] See Figure 4 , Figure 5 and Figure 6 In some embodiments, the support member 200 includes a support ring 210, a first sleeve 231, and a second sleeve 232. The support ring 210 is horizontally arranged, and the first sleeve 231 and the second sleeve 232 are located on opposite sides of the support ring 210 in the thickness direction. For example, the first sleeve 231 is located on the upper side of the support ring 210 and is connected to the outer edge of the support ring 210, while the second sleeve 232 is connected to the inner edge of the support ring 210. The second sleeve 232 forms an atomizing chamber 2321, and a liquid guiding channel 2322 is formed on the second sleeve 232. The second sleeve 232 is sleeved between the first buffer member 410 and the second buffer member 420, that is, the first buffer member 410 is sleeved outside the second sleeve 232, the second sleeve 232 is sleeved outside the second buffer member 420, and the liquid guiding channel 2322 is formed on the second sleeve 232. The first buffer 410 abuts against the outer surface of the support ring 210 along the axial direction of the support member 200, thus limiting the position of the first buffer 410. In fact, the upper end of the first buffer 410 abuts against the outer surface of the support ring 210, and the lower end of the first buffer 410 abuts against the second step surface 1331, thus positioning the first buffer 410 along the axial direction of the support member 200, further improving the assembly accuracy and efficiency of the first buffer 410.

[0046] See Figure 2 , Figure 3 and Figure 5 In some embodiments, the electronic atomizing device 10 further includes a sealing element 500 for sealing the liquid storage chamber 111. The sealing element 500 is sleeved between the first sleeve 231 and the insertion tube 120, i.e., the first sleeve 231 is sleeved outside the sealing element 500, and the sealing element 500 is sleeved outside the insertion tube 120, such that the sealing element 500 seals against the first sleeve 231 and the insertion tube 120 radially along the support member 200, thus achieving fixation and sealing of the sealing element 500. The sealing element 500 may be made of silicone material.

[0047] See Figure 2 , Figure 3 and Figure 5 In some embodiments, the seal 500 includes a sealing body 510, a lug 520, and a convex ring 530. The lug 520 is annular and protrudes radially from the outer surface of the sealing body 510, while the convex ring 530 is annular and protrudes radially from the inner surface of the sealing body 510. During the installation of the seal 500, the first sleeve 231 is fitted over the sealing body 510, such that the upper end of the first sleeve 231 seals against the lug 520 along the axial direction of the support member 200, thus positioning the first sleeve 231 by the lug 520. The lower end of the sealing body 510 seals against the inner surface of the support ring 210, thus limiting the seal 500 by the support ring 210 along the axial direction of the support member 200. Furthermore, the convex ring 530 is sleeved on the outside of the insertion tube 120. There can be multiple convex rings 530, which are spaced apart along the axial direction of the sealing body 510. By setting the convex rings 530, the deformation capacity and sealing capacity of the sealing element 500 can be reasonably improved, thereby improving the sealing effect of the sealing element 500.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
