[0002] Traditional e-cigarette atomizer coils mostly use round holes to directly expel air, which cannot increase negative pressure or accelerate airflow inside the atomizer coil, resulting in poor atomization. Utility Model Content

[0003] Based on this, it is necessary to propose a speed-increasing valve that can boost the pressure of the air output from the atomizing coil. An atomizing coil and an atomizing device are also proposed.

[0005] In some embodiments, the adjusting block has a groove on the side facing away from the first end of the axial channel.

[0006] In some embodiments, the main body includes an inner ring wall, an outer ring wall and an end wall that are radially spaced from the inner ring wall along the central channel. The end wall connects one end of the inner ring wall and one end of the outer ring wall, and an insertion interface is formed between the other end of the inner ring wall and the other end of the outer ring wall. The inner ring wall encloses the axial channel.

[0007] In some embodiments, the length of the outer annular wall is less than the length of the inner annular wall in the axial direction of the axial channel.

[0008] In some embodiments, the circumferential dimension of the adjusting block gradually decreases along the radial direction and inwards from the central channel.

[0009] In some embodiments, the cross-section of the central channel is circular with multiple openings.

[0010] The second aspect of this application provides an atomizing core, comprising: a hollow core body, an oil storage component disposed within the core body, and a heating element; the speed-increasing valve, wherein the main body is installed at one end of the core body, and the central channel and the airflow groove between adjacent adjustment blocks are all connected to the inner cavity of the core body.

The end wall connects one end of the inner ring wall and one end of the outer ring wall. The inner ring wall and the outer ring wall are respectively snapped into the inner wall and the outer wall of the core.

[0013] A third aspect of this application provides an atomizing device, including the aforementioned atomizing core.

[0014] In this application, by adding adjusting blocks on the inner wall of the axial channel of the speed-increasing valve, the flow area of ​​the gas in the axial channel is reduced, resulting in the compression of the gas volume flowing through the axial channel, thus increasing the pressure and flow rate. Airflow grooves are provided between adjacent adjusting blocks to distribute the airflow as evenly as possible, thereby improving the fullness of the suction and enhancing the drawing quality.

[0031] The first aspect of this application discloses a speed-increasing valve for an atomizing core. The atomizing core can be used in an atomizing device to atomize an atomizing medium into a gas. The atomizing device can be, for example, an electronic cigarette, and the atomizing medium can be, for example, e-liquid. The atomizing devices disclosed in the embodiments of this application can be used, but are not limited to, electronic cigarettes, medical atomizers, and beauty instruments. In this application, an electronic cigarette is specifically used as an example for illustration.

[0032] refer to Figures 1 to 4 ,in Figure 1 This is a schematic diagram of the speed-increasing valve 10 from one perspective according to an embodiment of this application; Figure 2 This is a schematic diagram of the speed-increasing valve 10 from another perspective in an embodiment of this application. Figure 3 for Figure 1 The front view of the speed-increasing valve 10. Figure 4 for Figure 3 Sectional view along the AA direction.

[0033] The speed-increasing valve 10 includes a main body 110 and a pressure-increasing structure 120. The main body 110 is used to install onto the end of the core 210 of the atomizing core 20, and the main body 110 has a through axial channel 101. The two ends of the axial channel 101 in its own axial direction Z are respectively the first end (… Figure 4 The upper end) and the second end ( Figure 4 (The lower end of the middle). The second end is the air inlet, and the third end is the air outlet.

[0034] The pressurization and speed increase structure 120 is disposed at the second end of the axial passage 101. The pressurization and speed increase structure 120 includes a plurality of adjustment blocks 121 disposed on the inner wall of the axial passage 101. The plurality of adjustment blocks 121 are arranged at intervals in the circumferential direction so that an air flow groove 103 is formed between every two adjacent adjustment blocks, and a central passage 102 is formed between the free ends of the plurality of adjustment blocks 121.

[0035] Reference Figure 5 and Figure 6 , the atomizing core 20 includes a hollow core body 210, an oil storage member 220 disposed in the core body 210, and a heating element 230. The oil storage member 220 is configured to store liquid for atomization, such as e-liquid. The heating element 230 is configured to heat and atomize the e-liquid. When the main body 110 is mounted to the end of the core body 210 of the atomizing core 20, both the axial passage 101 and the central passage 102 communicate with the inner cavity of the core body 210 in the axial direction of the core body 210, so that the speed increase valve 10 can discharge the atomized air flow in the core body 210. Figure 5 wherein the second end of the axial passage 101 communicates with the inner cavity of the core body 210. In the present application, the axial direction of the core body 210 is the same as the axial direction of the axial passage 101, both being the Z direction.

[0036] The pressurization and speed increase structure 120 is specifically disposed at the second end of the axial passage 101 close to the core body 210. The pressurization and speed increase structure 120 is configured to pressurize the interior of the core body 210 and increase the flow rate of the air flow. Reference Figure 2 and Figure 4 , the end of the adjustment block 121 connected to the inner wall of the axial passage 101 is the connection end of the adjustment block 121, and the end far away from the inner wall of the axial passage 101 is the free end of the adjustment block 121. The plurality of adjustment blocks 121 are arranged at intervals in the circumferential direction, and the free ends of the plurality of adjustment blocks 121 converge toward the center of the axial passage, so that a central passage 102 is formed between the free ends of the plurality of adjustment blocks 121. In the circumferential direction of the axial passage 101, an air flow groove 103 is formed between any two adjacent adjustment blocks 121, and the plurality of adjustment blocks 121 together enclose the central passage 102. The axis of the central passage 102 coincides with the axis of the axial passage 101. In other words, by providing the plurality of adjustment blocks 121, the axial passage 101 is divided into the central passage 102 and the plurality of air flow grooves 103.

[0037] Optionally, the number of the adjustment blocks 121 is 4-8. Correspondingly, the total number of the air flow grooves 103 between adjacent adjustment blocks 121 is 3-7. Specifically, with reference to Figure 1 in this embodiment, the number of the adjustment blocks 121 is 5, and the total number of the air flow grooves 103 between adjacent adjustment blocks 121 is 4. It is easy to understand that the number and size of the air flow grooves 103 can be adjusted and changed according to the requirements of the pressurization amount and the acceleration amount.

[0038] The speed-increasing valve 10 of this application reduces the flow area of ​​the gas in the axial channel 101 by adding an adjusting block 121 on the inner wall of the axial channel 101. This compresses the gas volume flowing through the axial channel 101, increasing the pressure and flow rate. An airflow groove 103 is provided between adjacent adjusting blocks 121, which can distribute the airflow as evenly as possible, thereby improving the fullness of inhalation and enhancing the suction quality.

[0039] In some embodiments, the adjusting block 121 has a groove 122 on the side opposite to the first end of the axial channel 101. (See reference) Figure 2 and Figure 6 When the main body 110 is installed at the end of the core 210 of the atomizing core 20, the groove 122 faces the inner cavity of the core 210. With this design, the adjusting block 121 can prevent e-liquid and condensate inside the core 210 from flying into the mouth, and the groove 122 can collect e-liquid and condensate.

[0040] Thus, in the speed-increasing valve 10 of this application, the regulating block 121 reduces the flow area of ​​the axial channel 101, thereby compressing the gas volume flowing through the axial channel 101 and increasing the pressure and flow rate; on the other hand, the groove 122 of the regulating block 121 can effectively suppress the oil splatter phenomenon of the atomizing core 20 and prevent e-liquid and condensate from flying into the mouth.

[0041] In some embodiments, the main body 110 includes an inner ring wall 111, an outer ring wall 112 and an end wall 113 that are radially spaced from the inner ring wall 111 along the central channel 102. The end wall 113 connects one end of the inner ring wall 111 and one end of the outer ring wall 112. An insertion interface is formed between the other end of the inner ring wall 111 and the other end of the outer ring wall 112. The inner ring wall 111 encloses the axial channel 101.

[0042] The insertion interface formed between the inner ring wall 111 and the outer ring wall 112 can be inserted and mated with the upper end of the core 210, thereby assembling the speed-increasing valve 10 to the core 210. The end wall 113 abuts against the upper end of the core 210 to provide a sealing function, so that the airflow inside the core 210 can only be discharged through the axial channel 101.

[0043] Furthermore, in the axial direction Z of the axial channel 101, the length of the outer ring wall 112 is less than the length of the inner ring wall 111. The inner ring wall 111 is designed to be larger, and after being embedded in the core 210, the inner ring wall 111 can be as close as possible to the oil storage component 220 inside the core 210, thereby facilitating the faster extraction of the airflow formed by atomization.

[0044] refer to Figure 1 and Figure 2In some embodiments, the circumferential dimension of the adjusting block 121 gradually decreases along the radial direction and inwards of the central channel 102. "Along the radial direction and inwards" refers to the direction along the radial direction of the central channel 102 and towards its axis. In simpler terms, the adjusting block 121 is larger on the outside and smaller on the inside along the radial direction of the central channel 102.

[0045] With this design, the opening of the airflow slot 103 for connecting with the central channel 102 has a larger size in the circumferential direction, which facilitates the airflow in the central channel 102 to be dispersed into the airflow slot 103 between adjacent regulating blocks 121.

[0046] refer to Figure 2 In some embodiments, the cross-section of the central channel 102 is circular with multiple openings. In this application, the central channel 102 is connected to the airflow channel 103; therefore, the central channel 102 has multiple openings in its circumferential direction. The cross-section of the central channel 102 itself is circular with multiple openings.

[0047] It is understood that the cross-section of the central channel 102 is not limited to a circle. The shape of the cross-section of the central channel 102 can be adjusted according to the requirements of boost and acceleration.

[0048] refer to Figure 5 and Figure 6 The second aspect of this application provides an atomizing core 20, including a hollow core body 210, an oil storage component 220 and a heating element 230 disposed within the core body 210; and an acceleration valve 10 of any of the above embodiments, the main body 110 of the acceleration valve 10 being installed at one end of the core body 210, and the central channel 102 and the airflow groove 103 between adjacent adjusting blocks 121 being in communication with the inner cavity of the core body 210. In the atomizing core 20, the inner cavity of the core body 210 is in communication with the central channel 102 and the airflow groove 103 in the acceleration valve 10, so that the atomized airflow in the core body 210 is discharged through the central channel 102 and the airflow groove 103.

[0049] The atomizing core 20 of this application has an acceleration valve 10 mounted on the core body 210. An adjusting block 121 is added to the inner wall of the axial channel 101 of the acceleration valve 10, reducing the flow area of ​​the gas in the axial channel 101. This compresses the gas volume flowing through the axial channel 101, increasing the pressure and flow rate. An airflow groove 103 is provided between adjacent adjusting blocks 121, which can disperse the airflow as evenly as possible, thereby improving the fullness of inhalation and enhancing the inhalation experience.

[0050] refer to Figure 4 , Figure 5 and Figure 6Optionally, the main body 110 is snapped onto one end of the core 210, which facilitates the assembly and disassembly of the speed-increasing valve 10 and the core 210. Specifically, the inner ring wall 111 and the outer ring wall 112 of the main body 110 are snapped onto the inner wall and outer wall of the core 210, respectively.

[0051] refer to Figure 7 and Figure 8 A third aspect of this application also provides an atomizing device 100, including the aforementioned atomizing core 20 and housing 30, wherein the atomizing core 20 is housed within the housing 30. The atomizing device 100 also includes a power supply unit (not shown) assembled at the bottom of the housing 30.

[0052] The top of the housing 30 is provided with a suction port 310 that is axially connected to the speed-increasing valve 10. When the atomizing device 100 is in use, the user inhales through the suction port 310, and the atomized airflow in the atomizing core 20 flows out from the speed-increasing valve 10 and then enters the user's mouth through the suction port 310.

[0053] The atomizing device 100 of this application has an acceleration valve 10 installed on the atomizing core 20. An adjustment block 121 is added to the inner wall of the axial channel 101 of the acceleration valve 10 itself, which reduces the flow area of ​​the gas in the axial channel 101, thereby compressing the gas volume and increasing the pressure and flow rate. There are airflow grooves 103 between adjacent adjustment blocks 121, which can disperse the airflow as evenly as possible, thereby improving the fullness of inhalation and thus improving the inhalation quality.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. 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. Therefore, the protection scope of this patent application should be determined by the appended claims.
