DETAILED DESCRIPTION

[0028] It should be noted that the various embodiments / implementations provided in this application can be combined with each other without causing any contradiction. The detailed description in the specific implementation mode should be understood as an explanation of the purpose of this application and should not be regarded as an improper limitation on this application.

[0029] 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.

[0030] 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.

[0031] A main flow channel 1a is formed in the housing 1. A first flow port 1b is formed on one axial side wall of the housing 1, and a second flow port 1c is formed on the peripheral side wall of the housing 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.

[0032] At least part of the regulating member 2 is disposed in the main flow channel 1a, and the regulating member 2 slides along 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 slide in the axial direction relative to the casing 1 to open or close the first flow port 1b located on the side wall of the lower end of the casing 1, and adjust the distance between the regulating member 2 and the first flow port 1b to adjust the flow rate of the first flow port 1b entering the main flow channel 1a.

[0033] 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 6 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.

[0034] 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.

[0035] In one embodiment, please refer to Figure 7The 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.

[0036] The 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 slide axially along 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.

[0037] There is no special limitation on the form in which the adjusting member 2 slides in the axial direction. The user can manually apply a sliding force in the axial direction to operate the adjusting member 2 to slide, or the user can convert the rotational motion into linear motion through mechanical transmission methods such as threaded fitting, worm gear fitting, gear rack fitting, etc. to achieve relative sliding between the adjusting member 2 and the relative housing 1.

[0038] For example, in one embodiment, please refer to Figure 4 and Figure 5 The adjusting member 2 has a fully closed position for closing the first flow port 1b and a fully open position for avoiding the first flow port 1b in the axial sliding direction of the casing 1. The adjusting member 2 is threadedly matched with the casing 1, so that the adjusting member 2 can continuously slide between the fully closed position and the fully open position relative to the casing 1 along the axial direction during the circumferential rotation of the adjusting member 2 relative to the casing 1, so as to adjust the liquid outlet area of ​​the first flow port 1b. When the adjusting member 2 continuously slides between the fully closed position and the fully open position along the axial direction relative to the casing 1, the liquid outlet area of ​​the first flow port 1b continuously changes with the sliding of the adjusting member 2, so the flow regulating assembly 100 of the present application can realize stepless regulation of the flow rate.

[0039] The relative position of the threaded connection between the adjusting member 2 and the casing 1 is not particularly limited. In one embodiment, the adjusting member 2 can be a rod-shaped structure with an external thread on the circumferential side wall, and the inner circumferential wall of the main channel 1a is provided with an internal thread that cooperates with the external thread of the adjusting member 2. The internal thread of the main channel 1a is threadedly engaged with the external thread of the adjusting member 2, so that the adjusting member 2 can rotate circumferentially relative to the casing 1 while continuously sliding along the axial direction of the casing 1.

[0040] In one embodiment, please refer to Figure 3 and Figure 4 The adjusting member 2 includes a rod body 21 and a cover body 22. An installation opening 1d is formed at one axial end of the casing 1 away from the first flow port 1b. One end of the rod body 21 extends into the main flow channel 1a through the installation opening 1d. The cover body 22 is connected to the axial end of the rod body 21 away from the first flow port 1b. The cover body 22 includes a cover plate 221 connected to one end of the rod body 21 and a surrounding plate 222 arranged around the outer peripheral side of the cover plate 221. The inner peripheral wall of the surrounding plate 222 is threadedly sleeved with the outer peripheral wall of the casing 1. In this way, the user can directly operate the cover body 22 to drive the rotation of the entire adjusting member 2. Since the cover body 22 is threadedly matched with the casing 1, the adjusting member 2 will also slide along the axial direction of the casing 1 as a whole during the rotation process. Specifically, the flow rate adjustment process from small to large is as follows: in the fully closed position, the end of the rod body 21 away from the installation opening 1d abuts against the first flow port 1b of the casing 1 to close the communication between the first flow port 1b and the main flow channel 1a. In the process of switching from the fully open position to the fully open position, the end of the rod body 21 away from the installation port 1d is separated from the casing 1, and slides relative to the casing 1 in the axial direction away from the first flow port 1b, and the gap between the rod body 21 and the first flow port 1b gradually increases, and finally in the fully open position, when the gap between the rod body 21 and the first flow port 1b reaches the maximum value. Exemplarily, in one embodiment, the height of the enclosure 222 along the axial direction of the casing 1 is 6mm to 8mm; and / or, the height of the internal thread of the enclosure 222 along the axial direction of the casing 1 is 5mm to 7mm.

[0041] In one embodiment, the diameter of the thread is M4 to M36. That is to say, the size range of the outer diameter of the thread of the outer peripheral wall of the casing 1 is M4 to M36. Specifically, the outer diameter of the thread of the outer peripheral wall of the casing 1 can be M4, M8, M12, M18, M27, M36 and other values. Specifically, when the user rotates the adjusting member 2 to a certain arc length, the larger the diameter of the thread, the smaller the angle of rotation of the adjusting member 2, the smaller the change in flow regulation, the lower the adjustment sensitivity, and the flow regulation is relatively slower and the flow regulation accuracy is relatively higher; conversely, when the user rotates the adjusting member 2 to a certain arc length, the smaller the diameter of the thread, the larger the angle of rotation, the larger the change in flow regulation, the higher the adjustment sensitivity, and the flow regulation is relatively faster. Therefore, the sensitivity of flow change can be adjusted by setting a suitable thread diameter, and the thread diameter can be set to M4 to M36 to obtain a suitable flow regulation sensitivity.

[0042] In one embodiment, the pitch of the thread is 0.5 mm to 3 mm. The axial distance that any point on the thread moves along the same spiral line for one revolution, that is, when the rotation angle of the adjusting member 2 is constant, the smaller the pitch, the smaller the distance that the adjusting member 2 slides along the axial direction, the smaller the change in flow regulation, the lower the adjustment sensitivity, and the flow regulation is relatively slower and the flow regulation accuracy is relatively higher; conversely, when the rotation angle of the adjusting member 2 is constant, the larger the pitch, the larger the distance that the adjusting member 2 slides along the axial direction, the larger the change in flow regulation, the higher the adjustment sensitivity, and the flow regulation is relatively faster.

[0043] In one embodiment, the flow regulating assembly 100 includes an elastic member 3, and the elastic force of the elastic member 3 is used to ensure that the threaded fitting between the regulating member 2 and the casing 1 is in close contact. In other words, the elastic force generated by the elastic member 3 can keep the threaded connection surface of the threaded fitting between the regulating member 2 and the casing 1 in close contact at all times, which can effectively prevent the thread from slipping, and ensure that each time the regulating member 2 rotates at any small angle relative to the casing 1, the regulating member 2 can slide relative to the casing 1 along the axial direction, thereby ensuring the regulation accuracy.

[0044] 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 4 For example, the inner peripheral wall of the main channel 1a is formed with a step surface 1f, and the two ends of the elastic member 3 are respectively connected to the cover plate 221 and the step surface 1f. Specifically, the elastic member 3 can be a compression spring or a tension spring sleeved on the rod body 21, and the two ends of the elastic member 3 are respectively connected to the lower end surface of the cover plate 221 and the step surface 1f to provide an elastic force for keeping the threaded connection surface in close contact.

[0045] For example, in one embodiment, please refer to Figure 4 The axial section of the casing 1 between the step surface 1f and the first flow port 1b is the first sleeve section 11, and the axial section of the casing 1 between the step surface 1f and the installation port 1d is the second sleeve section 12. Specifically, the first sleeve section 11 is used for guiding the flow at the first flow port 1b, and the second sleeve section 12 is used for threaded connection with the cover body 22 and sleeved with the elastic member 3. Therefore, the precision of the threaded connection between the second sleeve section 12 and the cover body 22 directly affects the flow adjustment precision. In this way, when processing the casing 1, it is only necessary to ensure the processing precision of the second sleeve section 12 to achieve fine adjustment of the flow, thereby reducing the overall processing cost and difficulty of the casing 1. For example, in one embodiment, the height of the first sleeve section 11 along the axial direction of the sleeve shell 1 is 14 mm to 20 mm; and / or, the outer diameter of the first sleeve section 11 is 5 mm to 8 mm; and / or, the inner diameter of the first sleeve section 11 is 3 mm to 4 mm; and / or, the height of the second sleeve section 12 along the axial direction of the sleeve shell 1 is 8 mm to 12 mm; and / or, the outer diameter of the second sleeve section 12 is 8 mm to 12 mm; and / or, the inner diameter of the second sleeve section 12 is 5 mm to 8 mm. In other words, the overall structural size of the second sleeve section 12 is greater than the overall structural size of the first sleeve section 11, so as to facilitate the assembly of the rod body 21 and the elastic member 3.

[0046] For example, in one embodiment, please refer to Figure 3 and Figure 4 The rod body 21 is a cylindrical structure, and includes a first rod segment 211 and a second rod segment 212. One end of the first rod end is close to the first flow port 1b, and the two ends of the second rod segment 212 are respectively connected to the cover body 22 and the end of the first rod segment 211 away from the first flow port 1b. Specifically, the first rod segment 211 is used to adjust the flow at the first flow port 1b, and the second rod segment 212 is used to connect the cover body 22 and the sleeve elastic member 3. With such a configuration, when processing the rod body 21, it is only necessary to ensure the processing accuracy of the first rod segment 211 to achieve fine adjustment of the flow, thereby reducing the overall processing cost and difficulty of the rod body 21. Exemplarily, in one embodiment, the height of the first rod segment 211 along the axial direction of the casing 1 is 5 mm to 8 mm; and / or, the outer diameter of the first rod segment 211 is 2 mm to 4 mm; and / or, the height of the second rod segment 212 along the axial direction of the casing 1 is 10 mm to 14 mm; and / or, the outer diameter of the second rod segment 212 is 3 mm to 5 mm.

[0047] In one embodiment, please refer to Figure 3 and Figure 4, a first frustum surface 1e whose cross-sectional diameter gradually increases in the direction away from the first flow port 1b is formed on the outer peripheral side of the first flow port 1b, and a second frustum surface 2a is formed on the peripheral side wall of the adjusting member 2 close to the axial end of the first flow port 1b, and the first frustum surface 1e abuts against the second frustum surface 2a to close the first flow port 1b. The first frustum surface 1e and the second frustum surface 2a cooperate with good centering, which can ensure that the adjusting member 2 can effectively close the first flow port 1b each time they abut. Compared with the abutment of a plane perpendicular to the axial direction, the sealing is better, and the gapless contact between the adjusting member 2 and the casing 1 can be ensured. Exemplarily, in one embodiment, the height of the first frustum surface 1e along the axial direction of the casing 1 is 1mm to 2mm.

[0048] The flow regulating assembly 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 pitch of the thread, the diameter of the thread, the shape and size parameters of the first flow port 1b, and the shape and size parameters of the rod body 21.

[0049] 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 3mm to 5mm.

[0050] 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.

[0051] 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 212 and the inner peripheral wall of the first sleeve segment 11. 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.

[0052] For example, in one embodiment, please refer to Figure 3 and Figure 4 , a limiting annular groove 2b 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 2b. In other words, the limiting annular groove 2b can be set on the adjusting member 2 or on the inner circumferential wall of the main flow channel 1a. The limiting annular groove 2b is used to limit the relative position of the sealing member 5 during the sliding process of the adjusting member 2 relative to the casing 1, so as to avoid the sealing member 5 from being worn or slipping off during the reciprocating sliding process of the adjusting member 2 along the axial direction of the casing 1, thereby improving the sealing reliability of the sealing member 5.

[0053] 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.

[0054] 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. Specifically, the width D1 of the flow regulating component 100 perpendicular to the axial direction can be 10 mm, 12 mm, 15 mm, 17 mm, 19 mm, 20 mm, etc. In one embodiment, please refer to Figure 4 , the height D2 of the flow regulating component 100 along the axial direction is 20mm to 30mm. Specifically, the height D2 of the flow regulating component 100 along the axial direction can take values ​​such as 20mm, 22mm, 25mm, 27mm, 29mm, 30mm, etc. In other words, by reasonably setting the structural dimensions of each component of the flow regulating component 100, the overall width of the flow regulating component 100 perpendicular to the axial direction is not greater than 20mm, and the overall height of the flow regulating component 100 along the axial direction is not greater than 30mm. While the overall structural dimensions of the existing flow regulating device along a certain direction are usually greater than 80mm, the overall structural dimensions of the flow regulating component 100 of the present application are smaller, the structure is more compact, and it can be applied to a portable electronic atomization device 1000.
