After long-term use, the sealing plug is prone to deformation at high temperature, which eventually leads to the problem of liquid leakage of the electronic atomization device, affecting the user experience. UTILITARIAN CONTENT

[0012] The atomization core assembly is connected with the atomization part, the liquid inlet channel is arranged in the liquid inlet part, and the atomization part and the liquid inlet part are arranged separately on the second shell.

[0013] In some embodiments, the second shell is arranged at the bottom of the first shell.

[0014] The first end of the liquid inlet channel is located at the side wall of the second shell and forms a liquid injection port at the side of the second shell, the second end of the liquid inlet channel extends from the liquid injection port into the liquid inlet part, and the liquid injection port is in communication with the side wall of the liquid inlet channel.

[0015] In some embodiments, the sealing assembly comprises an elastic member and a sealing member.

[0016] The elastic member is located at the second end of the liquid inlet channel and connected with the liquid inlet part, and the sealing member is connected with the elastic member, so that the sealing member closes the liquid injection port under the elastic force of the elastic member.

[0017] In some embodiments, the sealing assembly further comprises a sealing ring.

[0018] The outer diameter of the sealing member is smaller than the caliber of the liquid inlet channel, and the sealing ring is located on the outer wall of the sealing member to seal the gap between the sealing member and the side wall of the liquid inlet channel.

[0019] In some embodiments, the liquid inlet part further comprises a limiting part.

[0020] The limiting part is located in the liquid inlet channel, and the sealing member abuts against the limiting part under the elastic force of the elastic member.

[0021] In some embodiments, the top of the first shell is provided with a suction nozzle.

[0025] In some embodiments, the atomization device further comprises a power supply assembly.

[0026] The power supply assembly is electrically connected with the atomization core assembly to supply power to the atomization core assembly.

[0027] In the atomizing device described in the above embodiments, because the atomizing core assembly is located within the liquid storage chamber, it transfers heat to the sealing assembly while heating the aerosol matrix.

This allows the sealing assembly, used to open or close the inlet channel, to be located away from the atomizing core assembly, preventing direct heat transfer from the atomizing core assembly to the sealing assembly. This reduces deformation of the sealing assembly, making the atomizing device less prone to leakage after long-term use and improving its durability. Attached Figure Description

Specific Implementation

[0036] The present application will be further described in detail below with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0037] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0038] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0039] This application provides an atomizing device, such as... Figures 1 to 6 As shown, the atomizing device may include a housing 1, an atomizing core assembly 2, and a sealing assembly 3. The housing 1 is provided with a liquid storage chamber 111 and a liquid inlet channel 121 communicating with the liquid storage chamber 111. The liquid storage chamber 111 can be used to store an aerosol matrix, and the liquid inlet channel 121 can be used to inject the aerosol matrix into the liquid storage chamber 111. The atomizing core assembly 2 is disposed in the liquid storage chamber 111 and can be used to heat the aerosol matrix in the liquid storage chamber 111 to atomize and generate aerosol. The sealing assembly 3 is disposed in the liquid inlet channel 121 and can be moved to open or close the liquid inlet channel 121. The liquid storage chamber 111 and the liquid inlet channel 121 are separated on the housing 1 to isolate the sealing assembly 3 from the atomizing core assembly 2.

[0040] Since the atomization core assembly 2 is arranged in the liquid storage cavity 111, the atomization core assembly 2 will transmit heat to the blocking assembly 3 while heating the aerosol substrate, so that the blocking assembly 3 is deformed under high temperature for a long time, affecting the sealing effect of the blocking assembly 3. The liquid storage cavity 111 and the liquid inlet channel 121 are arranged separately on the shell 1, so that the blocking assembly 3 for opening or closing the liquid inlet channel 121 can be away from the atomization core assembly 2, so as to block the heat transmitted directly from the atomization core assembly 2 to the blocking assembly 3, thereby reducing the deformation of the blocking assembly 3, preventing the problem of liquid leakage after long-term use of the atomization device, and improving the durability of the atomization device.

[0041] In some embodiments, as shown in Figures 1 to 4 The shell 1 can include a first shell 11 and a second shell 12; the liquid storage cavity 111 is arranged in the first shell 11, and the liquid inlet channel 121 is arranged in the second shell 12. The first shell 11 is detachably connected with the second shell 12. The second shell 12 has a liquid inlet 122 communicating the liquid storage cavity 111 and the liquid inlet channel 121. The blocking assembly 3 is movable in the liquid inlet channel 121 to open or close the liquid inlet 122.

[0042] Therefore, by arranging the liquid storage cavity 111 and the liquid inlet channel 121 in the first shell 11 and the second shell 12 respectively, the liquid storage cavity 111 and the liquid inlet channel 121 can be completely separated, so that the heat of the atomization core assembly 2 can be prevented from being directly transmitted to the blocking assembly 3. At the same time, since the liquid storage cavity 111 and the liquid inlet channel 121 are arranged in the first shell 11 and the second shell 12 respectively, the blocking assembly 3 and the aerosol substrate are dry and wet separated, so that the rust problem caused by long-term soaking of the blocking assembly 3 in the aerosol substrate can be avoided. The first shell 11 can be detachably connected with the second shell 12 by insertion, screwing or clamping, so as to facilitate the assembly between the first shell 11 and the second shell 12. The specific connection mode between the first shell 11 and the second shell 12 is not specially limited in the present application.

[0043] In other embodiments, the shell 1 can also be arranged as an integrally formed structure. At the same time, a partition plate or a partition sleeve can be arranged in the liquid storage cavity 111 of the shell 1 to isolate the liquid inlet channel 121, and the blocking assembly 3 is installed in the partition plate or the partition sleeve, which can also block the heat transmitted by the atomization core assembly 2. The specific separation mode of the liquid storage cavity 111 and the liquid inlet channel 121 is not specially limited in the present application.

[0044] In addition, the blocking assembly 3 moves in the liquid inlet channel 121 to open or close the liquid inlet 122, so that the movement of the blocking assembly 3 in the liquid inlet channel 121 can play a guiding role, so that the blocking assembly 3 can always move in a fixed direction to open and close the liquid inlet channel 121, thereby avoiding the problem of deviation during movement of the blocking assembly 3 due to deformation after long-term use, and further ensuring the sealing effect of the blocking assembly 3.

[0045] In some embodiments, as shown in Figure 3 and Figure 4 The second shell 12 can include an atomization part 123 and a liquid inlet part 124; the atomization core assembly 2 is connected with the atomization part 123, the liquid inlet channel 121 is arranged in the liquid inlet part 124, and the atomization part 123 and the liquid inlet part 124 are arranged separately on the second shell 12.

[0046] For example, the atomization part 123 can be a sleeve arranged on the second shell 12, and the atomization core assembly 2 can be sleeved and fixed in the sleeve. The liquid inlet part 124 can be arranged separately from the atomization part 123 on the second shell 12, and the liquid inlet part 124 can be arranged in a block structure, and the liquid inlet channel 121 is embedded in the liquid inlet part 124. In this way, the blocking assembly 3 can be completely separated from the atomization core assembly 2. The specific structure and separation method of the atomization part 123 and the liquid inlet part 124 are not specially limited in the present application.

[0047] In some embodiments, as shown in Figure 3 and Figure 4 The second shell 12 is arranged at the bottom of the first shell 11; the first end of the liquid inlet channel 121 is located at the side wall of the second shell 12 and forms a liquid injection port 125 at the side of the second shell 12, the second end of the liquid inlet channel 121 extends from the liquid injection port 125 to the liquid inlet part 124, and the liquid inlet 122 is in communication with the side wall of the liquid inlet channel 121.

[0048] Because the aerosol hot gas flow formed after the atomization core assembly 2 heats the aerosol substrate flows towards the top of the first shell 11, the heat at the top of the first shell 11 is more concentrated than the heat at the bottom. Therefore, arranging the second shell 12 at the bottom of the first shell 11 allows the blocking assembly 3 to avoid the position where the heat is relatively concentrated, thereby reducing the deformation of the blocking assembly 3 and ensuring the sealing effect of the blocking assembly 3. Arranging the liquid inlet 122 at the side wall of the liquid inlet channel 121 allows the blocking assembly 3 to close the liquid inlet 122 by using the side wall, so that the blocking assembly 3 has a larger sealing area.

[0049] In addition, the liquid injection port 125 is arranged on the side of the second shell 12, so that the user can inject the aerosol substrate into the liquid storage cavity 111 from the side of the second shell 12, thereby avoiding the problem that the user is inconvenient to add liquid due to the liquid injection port 125 arranged on the bottom of the second shell 12. In other embodiments, the second shell 12 can also be arranged on the top of the first shell 11, so that the user can inject the aerosol substrate into the liquid storage cavity 111 from the top of the second shell 12. The present application does not specially limit the relative position relationship between the first shell 11 and the second shell 12.

[0050] In some embodiments, as shown in Figure 3 and Figure 4 The blocking assembly 3 can include an elastic member 31 and a blocking member 32. The elastic member 31 is arranged at the second end of the liquid inlet channel 121 and connected with the liquid inlet portion 124. The blocking member 32 is connected with the elastic member 31, so that the blocking member 32 closes the liquid inlet port 122 under the elastic force of the elastic member 31.

[0051] When it is necessary to add the aerosol substrate, the user can push the blocking member 32 to move away from the liquid injection port 125, so as to open the liquid inlet port 122. At this time, the elastic potential energy of the elastic member 31 increases. When the addition is completed, the blocking member 32 can be automatically reset under the elastic force of the elastic member 31, so as to close the liquid inlet port 122. During the whole movement process of the blocking member 32 opening or closing the liquid inlet port 122, the blocking member 32 is always limited in the liquid inlet channel 121, and the problem of the blocking member 32 running out of position will not occur.

[0052] The blocking member 32 can be selected from a sealing plug, a sealing column or a sealing cover, and the elastic member 31 can be selected from a spring, a spring sheet or a torsional spring. For example, the blocking member 32 can be arranged in a cylindrical sealing manner, and the elastic member 31 can be arranged in a spring. The two ends of the spring are respectively connected with the liquid inlet portion 124 and the blocking member 32. When the blocking member 32 is pushed to move away from the liquid injection port 125, the sealing plug can open the liquid inlet port 122. When the addition is completed, the side wall of the sealing plug can be reset and closed under the elastic force, so as to close the liquid inlet port 122. In addition, the blocking member 32 can also be arranged in a sealing cover structure, and the elastic member 31 can also be arranged in a torsional spring. The sealing cover can be closed under the elastic force of the torsional spring, so as to close the liquid inlet port 122. The present application does not specially limit the specific structure of the elastic member 31 and the blocking member 32.

[0053] In other embodiments, the blocking assembly 3 can also include a magnetic pair and the blocking member 32. When the blocking member 32 is pushed to open the liquid inlet port 122, the magnetic pair can accumulate magnetic repulsion force under the top pushing force, so that the blocking member 32 can be automatically reset under the magnetic repulsion force, so as to close the liquid inlet port 122. The present application does not specially limit the specific structure of the blocking assembly 3.

[0054] In some embodiments, as shown in Figure 5 The outer diameter of the plugging member 32 can be smaller than the inner diameter of the liquid inlet passage 121, and the sealing ring 320 is arranged on the outer wall of the plugging member 32 to seal the gap between the plugging member 32 and the side wall of the liquid inlet passage 121.

[0055] When the outer diameter of the plugging member 32 is smaller than the inner diameter of the liquid inlet passage 121, the plugging member 32 has a small sliding resistance in the liquid inlet passage 121. In order to seal the plugging member 32 and the liquid inlet passage 121, the sealing ring 320 is arranged on the outer wall of the plugging member 32, so that the plugging member 32 can be in contact with the side wall of the liquid inlet passage 121 through the sealing ring 320 when sliding in the liquid inlet passage 121 to seal, thereby reducing the sliding resistance of the plugging member 32 and ensuring the sealing effect of the plugging member 32. Along the length direction of the liquid inlet passage 121, two sealing rings 320 can be sleeved or integrally formed on both ends of the plugging member 32. When the plugging member 32 closes the liquid inlet 122, the liquid inlet 122 is located between the two sealing rings 320. Of course, the plugging member 32 can also have three or more sealing rings 320. The present application does not specially limit the connection mode between the sealing ring 320 and the plugging member 32 and the specific number of the sealing ring 320.

[0056] In other embodiments, the outer diameter of the plugging member 32 can also be greater than or equal to the inner diameter of the liquid inlet passage 121, so that the outer wall of the plugging member 32 is directly in contact with the inner wall of the liquid inlet passage 121 for sealing. In addition, the plugging member 32 can be arranged as a solid structure or a hollow structure, and the present application does not specially limit the specific shape of the plugging member 32.

[0057] In some embodiments, as shown in Figure 3 and Figure 4 The liquid inlet portion 124 can also have a limiting portion 126. The limiting portion 126 is located in the liquid inlet passage 121, and the plugging member 32 is in abutment with the limiting portion 126 under the elastic force of the elastic member 31.

[0058] For example, the limiting portion 126 can be a limiting column arranged in the liquid inlet passage 121. When the plugging member 32 closes the liquid inlet 122 under the elastic force of the elastic member 31, the plugging member 32 can be limited by abutting against the limiting column, so that the plugging member 32 stops at the position of closing the liquid inlet 122.

[0059] In other embodiments, the limiting portion 126 can also be a limiting step provided on the inner wall of the liquid inlet channel 121. When the sealing member 32 moves under the elastic force of the elastic member 31, the sealing member 32 can abut against the limiting step, and the sealing member 32 can also be stopped at the position of closing the liquid inlet 122. The specific structure of the limiting portion 126 is not specially limited in the present application.

[0060] In some embodiments, as shown in Figures 2 to 4 , the top of the first shell 11 is provided with a suction nozzle 112; the atomization core assembly 2 is connected with the suction nozzle 112 through the atomization portion 123, and the sealing member 32 moves in the liquid inlet channel 121 in a direction away from the atomization core assembly 2 and closes the liquid inlet 122.

[0061] In some embodiments, as shown in Figure 4 , the atomization core assembly 2 can be arranged along the Y direction (vertical direction), and the aerosol formed after being atomized through the atomization core assembly 2 can be discharged through the suction nozzle 112. The liquid inlet channel 121 can be arranged along the X direction (horizontal direction), and since the sealing member 32 is mostly in the state of closing the liquid inlet 122 during normal use of the atomization device. Therefore, the position of the sealing member 32 closing the liquid inlet 122 is arranged at the end of the liquid inlet channel 121 away from the atomization core assembly 2, so that the straight-line distance between the sealing member 32 and the atomization core assembly 2 is the farthest, thereby facilitating the reduction of the adverse effects of high temperature on the sealing member 32, so as to ensure the sealing effect of the sealing member 32.

[0062] In some embodiments, as shown in Figure 3 and Figure 4 , the atomization device can further include a sealing member 4; the sealing member 4 is located between the first shell 11 and the second shell 12, and the first shell 11 and the sealing member 4 form a liquid storage cavity 111, the liquid inlet 122 penetrates the sealing member 4, and a part of the atomization core assembly 2 penetrates the sealing member 4.

[0063] The sealing member 4 can seal the gap between the first shell 11 and the second shell 12 to prevent leakage of the aerosol substrate from the gap between the first shell 11 and the second shell 12. Wherein, a groove (not shown in the figure) can be arranged at the bottom of the sealing member 4 along the circumferential direction of the sealing member 4, and the top of the second shell 12 can be inserted into the groove, so that the sealing member 4 is connected with the second shell 12. The second shell 12 can be inserted and matched with the first shell 11, so that the sealing member 4 and the first shell 11 form the liquid storage cavity 111. Thus, the installation of the atomization device is simple and convenient.

[0064] In other embodiments, the sealing member 4 and the second shell 12 can also be connected by bonding. The first shell 11 and the second shell 12 can also be connected by screwing or clamping. The present application does not specially limit the specific connection mode between the first shell 11, the second shell 12 and the sealing member 4.

[0065] In some embodiments, as shown in Figs. 1 and 2, the atomization device can further include a power supply assembly 5; the power supply assembly 5 is electrically connected with the atomization core assembly 2 to supply power to the atomization core assembly 2. Figure 1 and Figure 6 The atomization device can further include a power supply assembly 5; the power supply assembly 5 is electrically connected with the atomization core assembly 2 to supply power to the atomization core assembly 2.

[0066] The atomization core assembly 2 can include an atomization tube, a heating element and a liquid absorbing element. The atomization tube can be installed on the atomization portion 123 and communicate with the suction nozzle 112. The liquid absorbing element can be sleeved on the atomization tube to absorb the aerosol substrate in the liquid storage cavity 111. The heating element can be sleeved in the atomization tube to heat the aerosol substrate absorbed by the liquid absorbing element and generate aerosol. The aerosol can be discharged from the suction nozzle 112. The present application does not specially limit the specific structure of the atomization core assembly 2.

[0067] In addition, the power supply assembly 5 can include a power source 51 and a power source shell 52. The power source 51 can be installed in the power source shell 52, and the power source 51 can be electrically connected with the heating element of the atomization core assembly 2 to provide power for the heating element. The power source shell 52 can be detachably connected with the first shell 11. In other embodiments, the power source shell 52 and the first shell 11 can also be formed as an integral structure. The power supply assembly 5 can further include a circuit board, and the circuit board is electrically connected with the power source 51 and the heating element, respectively. The present application does not specially limit the specific structure of the power supply assembly 5.

[0068] The above application of specific examples to the present application is only used to help understand the present application and does not limit the present application. For those skilled in the art to which the present application belongs, according to the idea of the present application, a number of simple deductions, deformations or substitutions can be made.
