[0004] In view of this, the purpose of this application is to provide an atomizing device that aims to solve the technical problems of leakage of atomizing matrix and accidental activation of atomizing devices during mobile transportation in related technologies.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] An embodiment of this application provides an atomizing device, comprising:

[0007] A housing having an air outlet portion and an air outlet channel provided therein;

[0008] A bracket having an air intake channel;

[0009] An atomizing component is disposed on the bracket and extends from the bracket to the air outlet. The atomizing component is provided with an atomizing channel, one end of which is connected to the air inlet channel and the other end of which is connected to the air outlet channel.

[0010] Rolled rods;

[0011] The atomizing assembly further includes a sheet-shaped liquid guiding element and a heating element disposed within the atomizing channel, wherein the liquid guiding element and the heating element are stacked and wound along the outer periphery of the winding rod.

[0012] The rolled rod passes through the atomizing channel and is interference-fitted with the air inlet channel of the bracket and the air outlet channel of the air outlet section, respectively, and blocks the air inlet channel and the air outlet channel.

[0013] In one embodiment, the rolling bar includes a first segment, a second segment, and a third segment connected in sequence;

[0014] The first section passes through the atomizing channel and the air intake channel and is interference-fitted with the air intake channel, and blocks the air intake channel;

[0015] The second section is interference-fitted with the air outlet channel and blocks the air outlet channel;

[0016] The third section extends through the air outlet channel to the outside of the housing.

[0017] In one embodiment, the liquid guiding element and the heating element are stacked and wound around the outer periphery of the portion of the first segment located in the atomizing channel, and the diameter of the second segment is larger than the diameter of the first segment.

[0018] In one embodiment, the circumferential wall of the second segment is provided with a plurality of annular protrusions spaced apart along the axial direction of the rolled rod, and at least one of the annular protrusions is interference-fitted with the air outlet channel and blocks the air outlet channel.

[0019] In one embodiment, the diameter of the air outlet channel gradually increases along the direction towards the atomizing channel at one end of the air outlet channel, and the annular protrusion includes at least a first annular protrusion and a second annular protrusion, the first annular protrusion being located between the second annular protrusion and the first segment, and the diameter of the second annular protrusion being smaller than the diameter of the first annular protrusion.

[0020] In one embodiment, the diameter of the third segment is smaller than the diameter of the air outlet channel.

[0021] In one embodiment, the diameter of the third segment is D1, and the diameter of the air outlet channel is D2, satisfying the relationship: 0.7≤D1 / D2≤0.95.

[0022] In one embodiment, the winding rod further includes a fourth segment, which is connected to the end of the third segment away from the second segment.

[0023] The diameter of the fourth segment is smaller than the diameter of the air outlet channel, and / or the diameter of the fourth segment is smaller than the diameter of the third segment.

[0024] In one embodiment, an annular groove is provided on the circumferential wall at the connection between the fourth segment and the third segment.

[0025] In one embodiment, the housing has a receiving cavity with one end open, and the support is located in the receiving cavity to form a liquid storage space with the housing;

[0026] The atomizing device also includes a cover, which covers the opening and has an opening protruding toward the bracket at a position corresponding to the air intake channel. The opening has an air intake hole that communicates with the outside and the air intake channel.

[0027] The beneficial effects of this application are:

[0028] This application provides an atomizing device. By inserting a rolled rod through the atomizing channel and press-fitting it with the air inlet channel and the air outlet channel of the outlet section of the bracket, respectively, and sealing the air inlet and outlet channels, this effectively prevents leakage of the atomizing matrix inside the housing through the air inlet or outlet channels, thus avoiding the technical problem of atomizing matrix leakage during the movement and transportation of the atomizing device. On the other hand, it also prevents outside air from entering the atomizing channel through the air inlet channel and being discharged through the air outlet channel, thereby avoiding the technical problem of the airflow sensor erroneously detecting a suction signal and feeding it back to the controller during the movement and transportation of the atomizing device, causing the atomizing device to start erroneously.

[0029] When the atomizing device is needed, the coil is pulled out sequentially from the air inlet channel, atomizing channel, and air outlet channel under external force, so that the atomizing channel is connected to the air inlet channel and the air outlet channel respectively. In this way, when the user inhales, the outside air can flow through the air inlet channel, atomizing channel, and air outlet channel in sequence. During this process, the airflow sensor detects the suction signal and feeds it back to the controller. The controller controls the heating element of the atomizing component to turn on according to the suction signal fed back by the airflow sensor. The atomizing matrix in the shell is transported to the heating element through the liquid guide to atomize the atomizing matrix to generate an aerosol. The generated aerosol mixes with the outside air to form an aerosol product. The aerosol product is discharged through the air outlet channel for the user to use.

[0030] By stacking sheet-like liquid guiding components and heating elements and winding them along the outer periphery of a rolled rod, the sheet-like liquid guiding components and heating elements are easily wound into a columnar atomizing assembly with atomization channels, effectively improving the processing and installation efficiency of the atomizing assembly. In the prior art, the columnar atomizing assembly with atomization channels is first processed, and then a sealing component used to isolate the atomization channels from the outside air is inserted into the atomization channels, resulting in high installation difficulty and low installation efficiency of the sealing component. In this embodiment, the rolled rod is directly used as a support for the liquid guiding components and heating elements, and the rolled rod is also retained as a sealing component, saving costs, reducing installation difficulty, and increasing installation efficiency. On the other hand, the rolled rod is kept close to the atomization channels to seal the atomization channels, thereby further reducing the probability of atomization matrix leakage and false start-up during the movement and transportation of the atomizing device.

[0050] like Figure 1 As shown, an embodiment of this application provides an atomizing device 100, relating to the technical field of atomizing devices 100, mainly used to atomize an atomizing matrix into an aerosol for user use. The atomizing device 100 includes a housing 110, a support 120, an atomizing component 130, and a coiled rod 140.

[0051] See also Figure 2 and Figure 3The housing 110 has an air outlet 111, which is provided with an air outlet channel 1111. The bracket 120 has an air inlet channel 121. The atomizing component 130 is disposed on the bracket 120 and extends from the bracket 120 to the air outlet 111. The atomizing component 130 is provided with an atomizing channel 131, one end of which communicates with the air inlet channel 121, and the other end of which communicates with the air outlet channel 1111.

[0052] The atomizing assembly 130 further includes a sheet-shaped liquid guide 132 and a heating element 133 disposed within the atomizing channel 131. The liquid guide 132 and the heating element 133 are stacked and wound around the outer periphery of the coiled rod 140. The coiled rod 140 passes through the atomizing channel 131 and is press-fitted with the air inlet channel 121 of the support 120 and the air outlet channel 1111 of the air outlet section 111, respectively, and blocks the air inlet channel 121 and the air outlet channel 1111.

[0053] The atomizing device 100 provided in the embodiments of this application, by inserting a rolled rod 140 through the atomizing channel 131 and press-fitting it with the air inlet channel 121 of the support 120 and the air outlet channel 1111 of the air outlet 111 respectively, and sealing the air inlet channel 121 and the air outlet channel 1111, can prevent the atomizing matrix inside the housing 110 from leaking through the air inlet channel 121 or the air outlet channel 1111, thereby effectively avoiding the technical problem of atomizing matrix leakage that is prone to occur during the movement and transportation of the atomizing device 100. On the other hand, it can also prevent outside air from entering the atomizing channel 131 through the air inlet channel 121 and being discharged through the air outlet channel 1111, thereby avoiding the technical problem that the airflow sensor of the atomizing device 100 may mistakenly detect a suction signal and feed it back to the controller during the movement and transportation of the atomizing device 100, causing the atomizing device 100 to start erroneously.

[0054] When the atomizing device 100 is needed, the coiled rod 140 is pulled out sequentially from the air inlet channel 121, the atomizing channel 131, and the air outlet channel 1111 under external force, so that the atomizing channel 131 is connected to the air inlet channel 121 and the air outlet channel 1111 respectively. In this way, when the user inhales, the outside air can flow through the air inlet channel 121, the atomizing channel 131, and the air outlet channel 1111 in sequence. During this process, the airflow sensor detects the suction signal and feeds it back to the controller. The controller controls the heating element 133 of the atomizing component 130 to turn on according to the suction signal fed back by the airflow sensor. The atomizing matrix in the housing 110 is transported to the heating element 133 through the liquid guide 132 to atomize the atomizing matrix to generate an aerosol. The generated aerosol mixes with the outside air to form an aerosol product. The aerosol product is discharged through the air outlet channel 1111 for the user to use.

[0055] By stacking the sheet-like liquid guiding element 132 and the heating element 133 and winding them along the outer periphery of the winding rod 140, it is easier to form a columnar atomizing assembly 130 with an atomization channel 131 by winding the sheet-like liquid guiding element 132 and the heating element 133, thus effectively improving the processing and installation efficiency of the atomizing assembly 130. In the prior art, the columnar atomizing assembly with an atomization channel is first processed, and then a sealing element used to isolate the atomization channel from the external air is inserted into the atomization channel, resulting in the technical problems of high installation difficulty and low installation efficiency of the sealing element. In this embodiment, the rolled rod 140 is directly used as a support for the liquid guide 132 and the heating element 133, and is wound into shape. At the same time, the rolled rod 140 is retained as a sealing element, which saves costs, reduces installation difficulty and increases installation efficiency. On the other hand, the rolled rod 140 is made to fit tightly against the atomization channel 131 to seal the atomization channel 131, thereby further reducing the probability of atomization matrix leakage and false start-up during the movement and transportation of the atomization device 100.

[0056] For example, the material of the rolled rod 140 can be silicone or rubber, the liquid guiding component 132 can be a sheet of liquid guiding cotton, and the heating component 133 can be a sheet of heating mesh. The sheet of liquid guiding cotton and the heating wire are stacked and wound along the outer periphery of the rolled rod 140 to form a columnar atomizing assembly 130 with an atomizing channel 131.

[0057] like Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, the rolled rod 140 includes a first segment 141, a second segment 142, and a third segment 143 connected in sequence; the first segment 141 passes through the atomizing channel 131 and the air inlet channel 121 and is interference-fitted with the air inlet channel 121, and blocks the air inlet channel 121; the second segment 142 is interference-fitted with the air outlet channel 1111 and blocks the air outlet channel 1111; the third segment 143 extends through the air outlet channel 1111 to the outside of the housing 110.

[0058] In this embodiment, by inserting the first segment 141 through the atomizing channel 131 and the air inlet channel 121 with an interference fit and sealing the air inlet channel 121, and by inserting the second segment 142 with an interference fit and sealing the air outlet channel 1111, the atomizing matrix inside the housing 110 can be prevented from leaking through the air inlet channel 121 or the air outlet channel 1111, thereby effectively avoiding the technical problem of atomizing matrix leakage during the movement and transportation of the atomizing device 100. On the other hand, it can also prevent outside air from entering the atomizing channel 131 through the air inlet channel 121 and being discharged through the air outlet channel 1111, thereby avoiding the technical problem of the airflow sensor of the atomizing device 100 erroneously detecting the suction signal and feeding it back to the controller during the movement and transportation of the atomizing device 100, which would lead to the atomizing device 100 being falsely activated.

[0059] Meanwhile, by extending the third segment 143 through the air outlet channel 1111 to the outside of the housing 110, the user can pull out the entire rolled rod 140 sequentially from the air inlet channel 121, the atomization channel 131 and the air outlet channel 1111 through the third segment 143 when using the atomizing device 100. This allows the atomization channel 131 to be connected to the air inlet channel 121 and the air outlet channel 1111 respectively, so that outside air can enter the atomization channel 131 through the air inlet channel 121 and mix with the aerosol generated in the atomization channel 131 to form an aerosol product. The aerosol product can be discharged through the air outlet channel 1111 for the user to use.

[0060] For example, the first segment 141, the second segment 142 and the third segment 143 can be integrally molded from silicone or rubber.

[0061] like Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, the liquid guiding element 132 and the heating element 133 are stacked and wound around the outer periphery of the portion of the first segment 141 located in the atomizing channel 131, and the diameter of the second segment 142 is larger than the diameter of the first segment 141.

[0062] In this embodiment, the liquid guiding component 132 and the heating component 133 are stacked and wound around the outer periphery of the portion of the first segment 141 located in the atomizing channel 131. This facilitates the winding and forming of the sheet-like liquid guiding component 132 and the heating component 133 into a columnar atomizing assembly 130 with an atomizing channel 131, effectively improving the processing and installation efficiency of the atomizing assembly 130. In related technologies, the columnar atomizing assembly with an atomizing channel is first processed, and then a sealing component used to isolate the atomizing channel from the external air is inserted into the atomizing channel, resulting in high installation difficulty and low installation efficiency of the sealing component. In this embodiment, the rolled rod 140 is directly used as a support for the liquid guide 132 and the heating element 133, and is wound into shape. At the same time, the rolled rod 140 is retained as a sealing element, which saves costs, reduces installation difficulty and increases installation efficiency. On the other hand, the first section 141 is in close contact with the atomization channel 131 to block the atomization channel 131, thereby further reducing the probability of atomization matrix leakage and false start-up during the movement and transportation of the atomization device 100.

[0063] By setting the diameter of the second segment 142 to be larger than that of the first segment 141, the diameter of the second segment 142 is larger than that of the atomizing channel 131. Thus, during the process of the sheet-like liquid guide 132 and heating element 133 being stacked and wound along the outer periphery of the portion of the first segment 141 located in the atomizing channel 131, the second segment 142 can limit the liquid guide 132 and heating element 133, preventing them from deviating from the portion of the first segment 141 located in the atomizing channel 131 during winding, thereby ensuring winding stability and positional accuracy.

[0064] like Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, the circumferential wall of the second segment 142 is provided with a plurality of annular protrusions spaced apart along the axial direction of the rolled rod 140, and at least one of the annular protrusions is interference-fitted with the air outlet channel 1111 and blocks the air outlet channel 1111.

[0065] In this embodiment, by providing multiple annular protrusions spaced apart along the axial direction of the rolled rod 140 on the circumferential wall of the second section 142, and by press-fitting at least one annular protrusion with the air outlet channel 1111 to seal the air outlet channel 1111, even if the assembly position of the second section 142 changes along its axial direction when it is assembled into the air outlet channel 1111, the air outlet channel 1111 can still be sealed, effectively improving the sealing stability of the air outlet channel 1111 and reducing the probability of leakage of the atomizing matrix and false start-up of the atomizing device 100 during transportation.

[0066] like Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, the diameter of the air outlet channel 1111 near the atomizing channel 131 gradually increases along the direction toward the atomizing channel 131. The annular protrusion includes at least a first annular protrusion 1421 and a second annular protrusion 1422. The first annular protrusion 1421 is located between the second annular protrusion 1422 and the first segment 141. The diameter of the second annular protrusion 1422 is smaller than the diameter of the first annular protrusion 1421.

[0067] In this embodiment, during the assembly of the support 120, atomizing component 130, and rolled rod 140 into the housing 110, the third segment 143 and the second segment 142 of the rolled rod 140 are sequentially assembled into the air outlet channel 1111. By setting the end of the air outlet channel 1111 near the atomizing channel 131 to gradually increase in diameter in the direction toward the atomizing channel 131, it is easier for the third segment 143 to pass through the end of the air outlet channel 1111 near the atomizing channel 131 and thus effectively improve the assembly efficiency.

[0068] By placing the first annular protrusion 1421 between the second annular protrusion 1422 and the first segment 141, the second annular protrusion 1422 is assembled into the air outlet channel 1111 before the first annular protrusion 1421. At the same time, by setting the diameter of the second annular protrusion 1422 to be smaller than the diameter of the first annular protrusion 1421, it is beneficial for the third segment 143 and the second annular protrusion 1422 with a smaller interference fit to be smoothly assembled into the air outlet channel 1111 first, and then the first annular protrusion 1421 with a larger interference fit to completely block the air outlet channel 1111. This effectively improves the assembly smoothness of the coiled rod 140 and the sealing performance of the coiled rod 140 to the air outlet channel 1111.

[0069] like Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, the diameter of the third segment 143 is smaller than the diameter of the air outlet channel 1111.

[0070] In this embodiment, during the assembly of the bracket 120, atomizing component 130, and rolled rod 140 into the housing 110, the third segment 143 and the second segment 142 of the rolled rod 140 are sequentially assembled into the air outlet channel 1111. By setting the diameter of the third segment 143 to be smaller than the diameter of the air outlet channel 1111, it is beneficial for the third segment 143 to pass smoothly through the air outlet channel 1111 first, and then for the second segment 142 with a larger interference fit to completely block the air outlet channel 1111. This effectively improves the assembly smoothness of the rolled rod 140 and the sealing performance of the rolled rod 140 to the air outlet channel 1111. On the other hand, the diameter of the third section 143 is smaller than the diameter of the air outlet channel 1111, so that there is a gap between the third section 143 and the air outlet channel 1111 for accommodating the atomizing matrix. In this way, even if the second section 142 fails to seal and leaks the atomizing matrix, it will be stuck in the gap and will not leak out of the housing 110, further reducing the probability of atomizing matrix leakage during the movement and transportation of the atomizing device 100.

[0071] In one embodiment, the diameter of the third segment 143 is D1, and the diameter of the air outlet channel 1111 is D2, satisfying the relationship: 0.7≤D1 / D2≤0.95.

[0072] In this embodiment, by controlling the diameter ratio of the third segment 143 to the air outlet channel 1111 between 0.7 and 0.95, the diameter of the third segment 143 is slightly smaller than the diameter of the air outlet channel 1111. This avoids the technical problem of excessively large gaps between the third segment 143 and the air outlet channel 1111, which could lead to leakage of the atomized matrix outside the housing 110 when the second segment 142 fails to seal. On the other hand, it also avoids the technical problem of excessively small gaps between the third segment 143 and the air outlet channel 1111, which could cause difficulties in assembling the rolled rod 140.

[0073] For example, the ratio of the diameter of the third segment 143 to the diameter of the air outlet channel 1111 can be 0.7, 0.75, 0.8, 0.85, 0.9, 0.91, 0.92, 0.95, etc. The specific ratio can be designed according to the actual needs of the product, and will not be listed here.

[0074] like Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, the rolled rod 140 further includes a fourth segment 144, which is connected to the end of the third segment 143 away from the second segment 142. The diameter of the fourth segment 144 is smaller than the diameter of the air outlet channel 1111, and / or the diameter of the fourth segment 144 is smaller than the diameter of the third segment 143.

[0075] In this embodiment, the fourth segment 144 is connected to the end of the third segment 143 furthest from the second segment 142. During the assembly of the bracket 120, the atomizing component 130, and the coiled rod 140 into the housing 110, the fourth segment 144, the third segment 143, and the second segment 142 of the coiled rod 140 pass through or are assembled into the air outlet channel 1111 in sequence. By setting the diameter of the fourth segment 144 to be smaller than the diameter of the air outlet channel 1111, it is beneficial for the fourth segment 144 and the third segment 143 to pass through the air outlet channel 1111 smoothly first, and then for the second segment 142 with a larger interference fit to completely block the air outlet channel 1111. This effectively improves the assembly smoothness of the coiled rod 140 and the sealing performance of the coiled rod 140 to the air outlet channel 1111. On the other hand, when the bracket 120, atomizing component 130 and coiled rod 140 are not fully assembled and the fourth section 144 passes through the air outlet channel 1111 and is located outside the housing 110, the user can push the bracket 120, atomizing component 130 and coiled rod 140 toward the housing 110, and pull the fourth section 144 to help the bracket 120, atomizing component 130 and coiled rod 140 be fully assembled into the housing 110, which effectively improves the ease and efficiency of installation and reduces the difficulty of installation.

[0076] By setting the diameter of the fourth segment 144 to be smaller than that of the third segment 143, the diameter of the fourth segment 144 is much smaller than that of the air outlet channel 1111, resulting in a larger gap between the fourth segment 144 and the air outlet channel 1111, which further improves the assembly smoothness of the rolled rod 140.

[0077] For example, the first segment 141, the second segment 142, the third segment 143 and the fourth segment 144 can be integrally molded from silicone or rubber.

[0078] like Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, an annular groove 145 is provided on the circumferential wall at the connection between the fourth segment 144 and the third segment 143.

[0079] In this embodiment, an annular groove 145 is formed on the circumferential wall at the connection between the fourth segment 144 and the third segment 143. This facilitates the assembly personnel to determine whether the bracket 120, atomizing component 130, and coiled rod 140 are installed correctly by observing the relative position of the annular groove 145 and the housing 110, ensuring positional accuracy. On the other hand, the annular groove 145 also serves as a gripping point to increase the friction between the fingers and the coiled rod 140, making it easier for the user to pull the coiled rod 140 out of the air inlet channel 121, atomizing channel 131, and air outlet channel 1111 by gripping the annular groove 145 when using the atomizing device 100, thus connecting the air inlet channel 121, atomizing channel 131, and air outlet channel 1111.

[0080] like Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, the housing 110 has a receiving cavity 112 with an opening 113 at one end, and the support 120 is located in the receiving cavity 112 to form a liquid storage space 160 with the housing 110. The atomizing device 100 also includes a cover 150, which covers the opening 113, and the cover 150 has an opening 151 protruding towards the support 120 at a position corresponding to the air inlet channel 121. The opening 151 has an air inlet hole 1511 communicating with the outside and the air inlet channel 121.

[0081] In this embodiment, the housing 110 has a receiving cavity 112 with an opening 113 at one end. The support 120 is disposed in the receiving cavity 112 to form a liquid storage space 160 for storing the atomizing matrix with the housing 110. By covering the opening 113 with the cover 150, the support 120 is stably installed in the receiving cavity 112, thereby ensuring the installation stability of the atomizing assembly 130 and the coiling rod 140.

[0082] By providing an opening 151 at the position corresponding to the air inlet channel 121 on the cover 150, and opening an air inlet 1511 on the opening 151 to communicate with the outside and the air inlet channel 121, when the atomizing device 100 is needed, the coiled rod 140 is pulled out sequentially from the air inlet channel 121, the atomizing channel 131, and the air outlet channel 1111 under the action of external force, so that the air inlet 1511, the air inlet channel 121, the atomizing channel 131, and the air outlet channel 1111 are connected, so that when the user inhales, the outside air can flow sequentially through the air inlet. 1511, air inlet channel 121, atomization channel 131 and air outlet channel 1111. During this process, the airflow sensor detects the suction signal and feeds it back to the controller. The controller controls the heating element 133 of the atomization component 130 to open according to the suction signal fed back by the airflow sensor. The atomization matrix in the receiving cavity 112 is transported to the heating element 133 through the liquid guide 132 to atomize the atomization matrix into an aerosol. The generated aerosol mixes with the outside air to form an aerosol product. The aerosol product is discharged through the air outlet channel 1111 for user use.

[0083] Meanwhile, by protruding the opening 151 toward the bracket 120, the air inlet 1511 on the opening 151 is far away from the bottom of the receiving groove of the cover 150, so that the leaked atomizing matrix can be contained by the bottom of the receiving groove, effectively reducing the probability of the atomizing matrix leaking to the outside through the air inlet 1511.

[0084] In one embodiment, the atomizing device 100 does not include a power supply component, and the atomizing device 100 is configured to work in conjunction with an external power supply component. In another embodiment, the atomizing device 100 further includes a power supply component electrically connected to the atomizing assembly 130, the power supply component being detachably or non-detachably disposed within the housing 110, or detachably or non-detachably disposed outside the housing 110.
