[0031] In the description of this application, the terms "upper", "lower", and "axial direction" are based on the attached Figure 4 It should be understood that these directional terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation of the present application. The term "first / second" is only used to distinguish different objects, and does not mean that there is any similarity or connection between the two.

[0032] One aspect of the present application provides a flow regulating assembly 100, see Figures 1 to 4 , including a housing 1 and an adjusting member 2.

[0033] A main flow channel 1a is formed in the casing 1; a first flow port 1b is formed on one axial side wall of the casing 1, and a second flow port 1c is formed on the peripheral side wall of the casing 1. The first flow port 1b and the second flow port 1c are both connected to the main flow channel 1a. Figure 4 For example, the housing 1 is a hollow tubular structure, the axial direction is the same as the up-down direction, the first flow port 1b and the second flow port 1c can be used for connecting the pipeline, and the liquid medium can flow into the main channel 1a from the first flow port 1b and flow out from the second flow port 1c. Alternatively, the liquid medium can also flow into the main channel 1a from the second flow port 1c and flow out from the first flow port 1b.

[0034] At least part of the regulating member 2 is disposed in the main flow channel 1a, and the regulating member 2 rotates around the axial direction of the casing 1 to adjust the flow rate of the first flow port 1b entering the main flow channel 1a. In other words, the regulating member 2 can be partially disposed in the main flow channel 1a, or can be completely disposed in the main flow channel 1a. Exemplarily, the lower end of the regulating member 2 is disposed in the main flow channel 1a, and can rotate around the axial direction of the casing 1. During the rotation process, the regulating member 2 can completely close the first flow port 1b or change the liquid outlet area of ​​the first flow port 1b, thereby adjusting the flow rate of the first flow port 1b entering the main flow channel 1a.

[0035] The flow regulating assembly 100 can be used in an electronic atomization device 1000. Taking the flow regulating assembly 100 of the embodiment of the present application as an example, refer to Figure 8 On the other hand, the present application provides an electronic atomization device 1000, including an air pump 200, an atomization chamber 210, a liquid storage chamber 220, an air supply channel 230, a liquid supply channel 240 and a flow regulating component 100 of any one of the embodiments described in the present application.

[0036] The air pump 200 supplies air to the atomizing chamber 210 through the air supply channel 230, and the liquid storage chamber 220 supplies liquid to the atomizing chamber 210 through the liquid supply channel 240. The airflow and the atomized liquid meet and mix in the atomizing chamber 210 to form atomized liquid droplets; the flow regulating component 100 is arranged on the liquid supply channel, the first flow port 1b is connected to the liquid storage chamber 220, and the second flow port 1c is connected to the atomizing chamber 210 to adjust the flow of the liquid supply channel. Specifically, the electronic atomizing device 1000 also includes an atomizing component with an atomizing chamber 210 and a liquid storage tank component with a liquid storage chamber 220. The liquid storage chamber 220 is used to contain and store atomized liquid. The atomized liquid includes but is not limited to liquid media such as liquid medicine, beauty liquid, and smoke liquid. That is to say, the electronic atomizing device 1000 can be used in the field of beauty atomization, the field of liquid medicine atomization, and the field of smoke liquid atomization. The atomized liquid is atomized in the atomizing chamber 210, and the liquid supply channel 240 is used to introduce the atomized liquid in the liquid storage chamber 220 into the atomizing chamber 210. The two ends of the air supply channel 240 are respectively connected to the atomizing chamber 210 and the pump air port of the air pump 200 to deliver the air flow pumped out by the air pump 200 to the atomizing chamber 210. The first flow port 1b is connected to the liquid storage chamber 220, and the second flow port 1c is connected to the atomizing chamber 210. The user can adjust the flow rate of the atomized liquid flowing into the atomizing chamber 210 from the liquid supply channel 240 by controlling the flow regulating component 100 in use to change the mist output of the atomizing component, thereby improving the user's experience.

[0037] In one embodiment, please refer to Fig. 9The electronic atomization device 1000 also includes a heater 250. Atomized liquid droplets formed after the airflow and the atomized liquid meet and mix in the atomization chamber 210 are sprayed out from the atomization chamber 210. The heater 250 can further heat and atomize the atomized liquid droplets sprayed from the atomization chamber 210 to form an aerosol with smaller particle size. Especially when the atomized liquid is a medicine liquid or a smoke liquid, the user experience can be further improved after secondary atomization by the heater 250.

[0038] A flow regulating assembly 100 provided in the embodiment of the present application has, on the one hand, a regulating member 2 and a casing 1. The regulating member 2 only needs to rotate around the axial direction of the casing 1 to directly adjust the flow rate of the first flow port 1b entering the main flow channel 1a. Compared with complex structures that require more energy and time to adjust, the overall structure of the flow regulating assembly 100 of the present application is simple and compact, the flow regulation changes are more linear and smooth, the corresponding time of flow regulation is shorter, and the working reliability of the flow regulating assembly 100 is high. On the other hand, the flow regulating assembly 100 can be arranged on the liquid supply channel of the electronic atomization device 1000. During use, the user can adjust the flow rate of the atomized liquid flowing from the liquid supply channel into the atomization chamber by controlling the flow regulating assembly 100, so that the liquid supply flow rate and the heating power of the atomization assembly are within a reasonable range, realizing the active control of the electronic atomization device 1000 on the flow regulation, and the quality of the aerosol generated after atomization is more stable, which improves the user's experience.

[0039] In one embodiment, Figures 4 to 7 , the regulating member 2 has a fully closed position and a fully open position. When the regulating member 2 is in the fully closed position, the regulating member 2 closes the first flow port 1b; when the regulating member 2 is in the fully open position, the liquid outlet area of ​​the first flow port 1b reaches the maximum; the regulating member 2 rotates continuously between the fully closed position and the fully open position to adjust the liquid outlet area of ​​the first flow port 1b. That is to say, when the regulating member 2 rotates continuously axially between the fully closed position and the fully open position relative to the casing 1, the liquid outlet area of ​​the first flow port 1b will change continuously with the rotation of the regulating member 2, so the flow regulating assembly 100 of the present application can achieve stepless regulation of the flow rate.

[0040] In one embodiment, please refer to Figures 5 to 7 A partial circumferential surface of one end of the adjusting member 2 facing the first flow outlet 1b forms a flow groove 2a, and the end surface of the adjusting member 2 facing the first flow outlet 1b is an adjusting surface 2b; when the adjusting member 2 is in a fully open position, the adjusting surface 2b is misaligned with at least part of the first flow outlet 1b, and when the adjusting member 2 is in a fully closed position, the adjusting surface 2b closes the first flow outlet 1b.

[0041] Specifically, the adjusting member 2 is a rod-shaped structure, the through-flow groove 2a is used to connect the first flow port 1b, the adjusting surface 2b is used to adjust the liquid outlet area of ​​the first flow port 1b, the casing 1 is formed with the first flow port 1b at one axial end thereof as a flow plate 121, the adjusting surface 2b of the adjusting member 2 abuts against the flow plate 121, and during the circumferential rotation of the adjusting member 2, the adjusting surface 2b can completely close the first flow port 1b or partially close the first flow port 1b or completely displace with the first flow port 1b, thereby continuously changing the liquid outlet area of ​​the first flow port 1b. When the adjusting member 2 is in the fully open position, on the projection plane perpendicular to the axial direction of the casing 1, the liquid outlet area of ​​the first flow port 1b flowing into the through-flow groove 2a reaches the maximum; when the adjusting member 2 is in the fully closed position, the adjusting surface 2b completely closes the first flow port 1b.

[0042] The shape of the first flow opening 1b is not particularly limited, and the first flow opening 1b can be circular, elliptical, square, polygonal, etc. In one embodiment, refer to Figure 5 , on the projection plane perpendicular to the axial direction of the casing 1, the projection of the first flow port 1b is an arc extending in the circumferential direction. The first flow port 1b is an arc-shaped structure, so that when the adjusting member 2 rotates a preset angle each time, the change in the liquid outlet area of ​​the first flow port 1b each time remains stable, and the user can accurately determine the current liquid outlet area of ​​the first flow port 1b according to the rotation angle of the adjusting member 2. Exemplarily, in one embodiment, the curvature range of the arc is 120° to 180°. Specifically, the curvature range of the arc can be 120°, 130°, 140°, 150°, 160°, 170°, 180° and other values.

[0043] In one embodiment, please refer to Figures 5 to 7 , on the projection plane perpendicular to the axial direction of the adjusting rod, the projection of the through-flow groove 2a is fan-shaped. Each time the preset angle is rotated, the radius edge of the fan cooperates with the arc structure of the first flow outlet 1b, which can evenly change the liquid outlet area of ​​the first flow outlet 1b, so that the change amount of the liquid outlet area of ​​the first flow outlet 1b each time remains stable, and further ensures that the current liquid outlet area of ​​the first flow outlet 1b can be accurately determined by the rotation angle of the adjusting member 2, so as to achieve precise adjustment of the liquid supply flow rate. Exemplarily, in one embodiment, the angle range of the fan is 100° to 150°. Specifically, the angle range of the fan can take values ​​such as 100°, 110°, 120°, 130°, 140°, and 150°.

[0044] In one embodiment, the radius of the inner arc edge 1ba of the first flow port 1b is 0.5 mm to 0.7 mm. Specifically, the radius of the inner arc edge 1ba can be 0.5 mm, 0.6 mm, or 0.7 mm. In one embodiment, the radius of the outer arc edge 1bb of the first flow port 1b is 0.9 mm to 1.1 mm. Specifically, the radius of the outer arc edge 1bb can be 0.9 mm, 1.0 mm, or 1.1 mm.

[0045] Since the fluid can pass through the gap between the inner arc edge 1ba of the first flow port 1b and the outer arc edge 1bb of the first flow port 1b, the larger the gap between the inner arc edge 1ba and the outer arc edge 1bb, the larger the change in the liquid outlet area of ​​the first flow port 1b each time the adjusting member 2 rotates by a preset angle, and the smaller the gap between the inner arc edge 1ba and the outer arc edge 1bb, the smaller the change in the liquid outlet area of ​​the first flow port 1b each time the adjusting member 2 rotates by a preset angle. Therefore, by reasonably setting the sizes of the inner arc edge 1ba and the outer arc edge 1bb, the change in the liquid outlet area of ​​the first flow port 1b can be effectively adjusted each time the adjusting member 2 rotates by a preset angle.

[0046] The flow regulating component 100 provided in the embodiment of the present application can realize precise regulation within a flow range of no more than 0.1 ml / s by reasonably setting the shape and size parameters of the first flow port 1b, the regulating surface 2b and the flow groove 2a.

[0047] In one embodiment, please refer to Figure 3 and Figure 4 The flow regulating assembly 100 includes an elastic member 3, and the two ends of the elastic member 3 are respectively connected to the casing 1 and the regulating member 2, so that the regulating member 2 and the axial side wall of the casing 1 where the first flow opening 1b is formed are kept in contact. In other words, the elastic force generated by the elastic member 3 will make the regulating surface 2b always contact the flow plate 121, which can prevent the regulating member 2 from sliding in the axial direction during the rotation of the casing 1, thereby preventing the first flow opening 1b from being directly connected to the main flow channel 1a after the regulating surface 2b is separated from the flow plate 121 in the axial direction, thereby ensuring the working reliability of the flow regulating assembly 100.

[0048] The structural form of the elastic member 3 is not particularly limited, and the elastic member 3 includes but is not limited to a spring, a spring sheet, a bellows, and other elastic structures with recoverable deformation. Figure 3 and Figure 4The sleeve 1 includes a sleeve cover 11 and a sleeve 12. A main flow channel 1a is formed in the sleeve 12. A first flow port 1b and a mounting port 1d are formed at both axial ends of the sleeve 12. One end of the adjusting member 2 close to the first flow port 1b extends into the main flow channel 1a through the mounting port 1d. The sleeve cover 11 is covered on the mounting port 1d. A step surface 2c is formed on the peripheral side wall of the adjusting member 2. Both ends of the elastic member 3 are connected to the sleeve cover 11 and the step surface 2c, respectively. Specifically, the connection method between the sleeve cover 11 and the sleeve 12 is not particularly limited, including but not limited to clamping, bolt and screw connection, welding, adhesive connection, etc. For example, in one embodiment, please refer to Figure X, the sleeve cover 11 includes a cover plate 111 covered at the mounting port 1d and a surrounding plate 112 surrounded by the outer peripheral side of the cover plate 111. The inner peripheral wall of the surrounding plate 112 is formed with an internal thread and the outer peripheral wall of the sleeve 12 is formed with an external thread. The surrounding plate 112 is threadedly sleeved with the sleeve 12. The cover 11 and the sleeve 12 are threadedly connected, which can facilitate the disassembly, assembly and maintenance of the adjusting member 2 and the elastic member 3. The elastic member 3 can be a compression spring sleeved on the adjusting member 2, when the two ends of the elastic member 3 are respectively connected to the lower end surface of the cover plate 111 and the step surface 2c, so that the adjusting member 2 and the flow plate 121 are kept in contact. Exemplarily, in one embodiment, the inner diameter of the sleeve 12 is between 3mm and 7mm; and / or the height of the sleeve 12 along the axial direction is 14mm to 20mm.

[0049] There is no particular limitation on the form in which the adjusting member 2 rotates around the axial direction of the casing 1. The user can manually apply a force to rotate around the axial direction of the casing 1 to operate the adjusting member 2 to rotate, or can operate the adjusting member 2 to rotate through mechanical transmission methods such as threaded matching, gear matching, etc., or can control the rotation of the adjusting member 2 through motor drive and other methods.

[0050] For example, in one embodiment, please refer to Figure 1 and Figure 4 , the end of the adjusting member 2 away from the first flow port 1b extends out of the main flow channel 1a and is formed with an operating portion 21 for cooperating with a tool. Specifically, a through hole 111a is formed on the cover plate 111 of the sleeve cover 11, and the operating portion 21 extends out of the main flow channel 1a through the through hole 111a. The operating portion 21 is used to provide a force point for the tool to operate the adjusting member 2 to rotate. The user can directly cooperate with the operating portion 21 through the tool to manually rotate the adjusting member 2. Alternatively, the operating portion 21 can be directly adapted to a motor, and the adjusting member 2 can be electrically driven to rotate by the motor. The structural form of the operating portion 21 is not particularly limited, please refer to Figure 1 The operating portion 21 is a platform surface formed on the outer peripheral wall of the adjusting member 2. Similarly, the operating portion 21 can also be configured as a toothed surface or other special-shaped surface adapted to a manual or electric operating tool.

[0051] In one embodiment, please refer to Figure 3 and Figure 4The adjusting member 2 is a cylindrical structure, and includes a first rod segment 22 and a second rod segment 23. An adjusting surface 2b and a flow groove 2a are formed at one end of the first rod segment 22. The other end of the first rod segment 22 is connected to the second rod segment 23. A step surface 2c is formed between the first rod segment 22 and the second rod segment 23. An operating portion 21 is formed at one end of the second rod segment 23 away from the first rod segment 22. Specifically, the first rod segment 22 is used to adjust the flow at the first flow port 1b, and the second rod segment 23 is used to cover the elastic member 3 and drive the first rod segment 22 to rotate. With such a configuration, when processing the adjusting member 2, it is only necessary to ensure the processing accuracy of the first rod segment 22 to achieve fine adjustment of the flow, thereby reducing the overall processing cost and difficulty of the adjusting member 2. Exemplarily, in one embodiment, the height of the first rod segment 22 along the axial direction of the casing 1 is 5 mm to 10 mm; and / or, the outer diameter of the first rod segment 22 is 2.9 mm to 6.9 mm; and / or, the height of the second rod segment 23 along the axial direction of the casing 1 is 15 mm to 20 mm; and / or, the outer diameter of the second rod segment 23 is 3 mm to 5 mm.

[0052] In one embodiment, please refer to Figure 3 and Figure 4 , the flow regulating assembly 100 includes a first connector 41 and a second connector 42; the first connector 41 is connected to the first flow port 1b, the second connector 42 is connected to the second flow port 1c, the extension direction of the first connector 41 is the same as the axial direction of the casing 1, and the extension direction of the second connector 42 is perpendicular to the axial direction of the casing 1. Specifically, the first connector 41 and the second connector 42 are both tubular structures with openings at both ends, and the end of the first connector 41 away from the first flow port 1b and the end of the second connector 42 away from the second flow port 1c are both used to connect external pipelines. The first connector 41 and the second connector 42 can facilitate the assembly and docking of external pipelines. Exemplarily, in one embodiment, the axial length of the first connector 41 and the second connector 42 is 5mm to 10mm; and / or, the inner diameter of the first connector 41 and the second connector 42 is 1mm to 3mm; and / or, the outer diameter of the first connector 41 and the second connector 42 is 4mm to 5mm.

[0053] For example, in one embodiment, please refer to Figure 3 and Figure 4 The outer peripheral wall of the first connector 41 away from the first flow port 1b is formed with a guide portion 4a, and / or the outer peripheral wall of the second connector 42 away from the second flow port 1c is formed with a guide portion 4a. Specifically, the guide portion 4a includes but is not limited to a chamfer or a rounded corner. The guide portion 4a can further facilitate the assembly and docking of the external pipeline.

[0054] In one embodiment, please refer to Figure 3 and Figure 4The flow regulating assembly 100 includes a seal 5, which is disposed between the inner peripheral wall of the main flow channel 1a and the outer peripheral wall of the regulating member 2. Specifically, the seal 5 is an annular structure, and the seal 5 is interference-fitted between the outer peripheral wall of the second rod segment 23 and the inner peripheral wall of the first sleeve segment. The seal 5 is used to prevent the liquid in the main flow channel 1a from leaking from the installation port 1d, so that the liquid can only enter and exit from the first flow port 1b and the second flow port 1c, thereby ensuring the reliability of flow regulation.

[0055] For example, in one embodiment, please refer to Figure 3 and Figure 4 , a limiting annular groove 2d is formed on one of the outer circumferential wall of the adjusting member 2 and the inner circumferential wall of the main flow channel 1a, and the sealing member 5 is embedded in the limiting annular groove 2d. In other words, the limiting annular groove 2d can be set on the adjusting member 2, or on the inner circumferential wall of the main flow channel 1a, and the limiting annular groove 2d is used to limit the relative position of the sealing member 5 during the axial rotation of the adjusting member 2 around the housing 1, to prevent the sealing member 5 from sliding along the axial direction during the rotation of the adjusting member 2, to prevent the sealing member 5 from falling off, and to improve the sealing reliability of the sealing member 5.

[0056] The material of the sealing member 5 includes, but is not limited to, flexible materials such as rubber, silicone, latex, etc. that are tightly sealed, have certain elasticity and wear resistance.

[0057] In one embodiment, please refer to Figure 4 , the width D1 of the flow regulating component 100 perpendicular to the axial direction is 10 mm to 20 mm.
