Detailed Implementation

[0022] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0023] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0024] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0025] This application addresses the problem of leakage caused by excessive hydraulic pressure in existing atomizing devices. A flow rate control component is installed between the liquid storage tank and the liquid storage element. The Tesla valve core of this component controls the flow rate of the atomizing matrix from the liquid storage tank to the liquid storage element, thereby reducing hydraulic pressure and avoiding leakage caused by excessive hydraulic pressure in existing technologies. This method offers advantages such as effective control of injection speed and prevention of leakage.

[0026] like Figure 1 , 2 As shown, in one embodiment, an atomizing component is provided, which can be used in an atomizing device. The atomizing component has a width direction, a depth direction, and a height direction, and may include: a liquid storage chamber 10, a flow rate control component 20, a liquid storage element 30, and an atomizing core component 40, etc., and can be used to heat the atomizing matrix to generate an aerosol.

[0027] The liquid storage chamber 10 is used to store the atomizing matrix and provide the atomizing matrix when the atomizing component is working.

[0028] The flow rate control assembly 20 may include a Tesla valve core 21 for controlling the flow rate. The Tesla valve core 21 includes an inlet 211, at least one Tesla valve unit 212 with a symmetrical structure, and an outlet 213 connected in sequence. The inlet 211 is connected to the storage tank 10, and the storage element 30 is connected to the outlet 213 to adsorb the atomizing matrix output from the outlet 213. The atomizing core assembly 40 heats and atomizes the atomizing matrix from the storage element 30 to form an aerosol.

[0029] The atomizing matrix flows from the inlet 211 to the outlet 213 in the same direction as the reverse flow direction of the Tesla valve unit 212, thus at least partially reversing the flow direction of the atomizing matrix. When liquid injection is required, the atomizing matrix of the storage tank 10 enters the Tesla valve unit 212 from the inlet 211. Since it enters from the reverse flow direction of the Tesla valve unit 212, the atomizing matrix encounters greater resistance when passing through the Tesla valve unit 212, resulting in a certain pressure drop and reducing the flow rate. This avoids leakage caused by excessive hydraulic pressure.

[0030] The reverse flow direction of the Tesla valve unit 212 is the direction that reduces the flow velocity of the liquid passing through it. For example... Figure 3As shown, liquid enters Tesla valve unit 212 from inlet 211 and then flows out from outlet 213, which is the reverse flow direction of Tesla valve unit 212. When liquid flows into Tesla valve unit 212 in the reverse flow direction, eddies or vortices are generated, resulting in relatively high resistance, thus allowing for flow rate control. Liquid enters Tesla valve unit 212 from outlet 213 and then flows out from inlet 211, which is the forward flow direction of Tesla valve unit 212. When liquid flows into Tesla valve unit 212 in the forward flow direction, no eddies or vortices are generated, resulting in relatively low resistance, allowing the fluid to pass smoothly through Tesla valve unit 212 without loss of flow rate.

[0031] Furthermore, based on the characteristics of the Tesla valve, when fluid flows in in the opposite direction, the faster the flow rate, the greater the resistance. When there is a large amount of atomized matrix in the reservoir 10, its pressure is high, meaning the flow rate entering the Tesla valve unit 212 is also fast. At this time, the Tesla valve unit 212 generates greater resistance, which can significantly reduce the flow rate. Conversely, when the amount of atomized matrix in the reservoir 10 decreases, its pressure also decreases, and the flow rate entering the Tesla valve unit 212 slows down. At this time, the Tesla valve unit 212 generates less resistance, and the reduction in flow rate is smaller, thus enabling dynamic adjustment of the hydraulic pressure.

[0032] In addition, the Tesla valve unit 212 of this application has a symmetrical structure, which can generate a counteracting effect when the diverted liquid flow reconverges, forming eddies and energy loss, thereby reducing the pressure of the liquid flow. This can better reduce the pressure of the atomizing matrix entering the liquid storage device 30, and avoid defects such as leakage caused by pressure on the liquid storage device 30.

[0033] like Figure 3 In one embodiment, the Tesla valve unit 212 includes two Tesla valve units 212 connected in series between the inlet 211 and the outlet 213. It is understood that the number of Tesla valve units 212 can be adjusted according to actual needs.

[0034] As shown in the figure, each Tesla valve unit 212 includes a main flow channel 2121, a branch flow channel, and a flow channel partition. The main flow channels 2121 of adjacent Tesla valve units 212 are connected. The inlet of the main flow channel 2121 is connected to the liquid inlet 211, and the outlet of the main flow channel 2121 is connected to the liquid outlet 213, so that the atomizing matrix can flow from the liquid inlet 211 into the main flow channel 2121 and flow out through the outlet of the main flow channel 2121.

[0035] The flow channel partition includes a first partition 2122 and a second partition 2123 symmetrically disposed on both sides of the main flow channel 2121. Correspondingly, the flow branching channel includes a first flow branching channel 2124 and a second flow branching channel 2125 symmetrically disposed outside the first partition 2122 and the second partition 2123, respectively.

[0036] The inlets of the first diversion channel 2124 and the second diversion channel 2125 are connected to the inlet of the main channel 2121, and the outlets of the first diversion channel 2124 and the second diversion channel 2125 are connected to the outlet of the main channel 2121, and a vortex zone is formed at the outlet of the first diversion channel 2124 and the second diversion channel 2125.

[0037] When the atomizing matrix flows in from the inlet 211, under the obstruction and diversion effect of the first partition 2122 and the second partition 2123, part of the atomizing matrix will flow into the first diversion channel 2124 and the second diversion channel 2125. When the atomizing matrix flows out from the outlet of the first diversion channel 2124 and the second diversion channel 2125, a counteracting effect is formed, creating a vortex zone, which counteracts the atomizing matrix in the main channel 2121, thereby damaging some energy and reducing the pressure. This allows for better control of the flow velocity of the atomizing matrix, achieving flow rate control.

[0038] Furthermore, when the pressure of the atomizing matrix flowing in from the inlet 211 decreases, the eddy effect of the main channel 2121, the first branch channel 2124, and the second branch channel 2125 is reduced, the pressure drop on the fluid is reduced, and the flow rate is not reduced excessively, ensuring smooth replenishment and realizing dynamic adjustment of hydraulic pressure.

[0039] In some embodiments, both the first partition 2122 and the second partition 2123 can be teardrop-shaped. The narrower portion of the teardrop shape is positioned near the inlet 211, allowing the atomizing matrix entering the main channel 2121 to be smoothly diverted to the first diversion channel 2124 and the second diversion channel 2125. The arc-shaped portion of the teardrop shape is positioned near the outlet 213, and the first diversion channel 2124 and the second diversion channel 2125 are also configured as arc-shaped channels corresponding to the arc-shaped portions of the teardrop shape. This allows the atomizing matrix to be ejected from the ends of the arc-shaped channels on both sides, forming a vortex and generating a countercurrent flow opposite to the flow direction of the main channel 2121, thereby reducing the flow velocity of the main channel 2121. This allows for better reduction of the flow velocity even when the inlet flow velocity is high, thus controlling the injection speed. As shown in the figure, the solid line represents the liquid flow direction of the main channel 2121, and the dashed line represents the countercurrent liquid flow direction formed by the diversion channels.

[0040] In one embodiment, such as Figure 4As shown, the width dimension L of the main channel 2121 is 0.6mm-1mm; and / or the depth dimension H of the main channel 2121 is 0.6mm-1mm. As shown in the figure, the X direction is the width direction of the atomizing component, the Y direction is the depth direction of the atomizing component, and the Z direction is the height direction of the atomizing component. It can be understood that the width and depth dimensions of the main channel 2121 can be adjusted according to the height and volume of the liquid storage chamber 10 to adapt to different injection speed requirements.

[0041] In one embodiment, such as Figure 3 , 4 As shown, the Z-direction represents the height direction of the Tesla valve. The width dimension of the cross-section in the height direction of the first diversion channel 2124 increases from its inlet to its outlet, forming a curved section at the outlet. Correspondingly, the width dimension of the cross-section in the height direction of the second diversion channel 2125 also increases from its inlet to its outlet, forming a curved section at the outlet. By gradually increasing the cross-sectional area, the flow velocity can be further reduced, thereby preventing excessive pressure at the outlet 213 due to excessive flow velocity. Furthermore, the curved section at the outlet can control the liquid flow direction at the outlet of the diversion channel, thereby controlling the formation of the vortex zone and better controlling energy loss to reduce the flow velocity of the main channel 2121.

[0042] In one embodiment, the number of Tesla valve units 212 is proportional to the height of the liquid storage tank 10. It is understood that when the height of the liquid storage tank 10 is higher, the pressure at the inlet 211 is greater, resulting in a higher flow rate into the flow rate control component 20. By increasing the number of Tesla valve units 212, the flow rate is gradually reduced, thereby achieving a more suitable flow rate at the outlet 213. This prevents excessive pressure on the atomizing matrix entering the liquid storage component 30, which could lead to insufficient adsorption capacity and leakage.

[0043] In one embodiment, when the rated height of the atomizing matrix stored in the liquid storage chamber 10 is less than 30 mm, the number of Tesla valve units 212 is 2-4.

[0044] When the rated height of the atomizing matrix stored in the liquid storage chamber 10 is greater than 30mm, the number of Tesla valve units 212 is 4-6.

[0045] Of course, the number of Tesla valve units 212 can be adjusted according to specific needs.

[0046] In one embodiment, the inlet 211 and the Tesla valve unit 212 are arranged in opposite directions parallel to the height direction; the outlet 213 is arranged in a direction parallel to the width direction. Figure 2As shown, in this embodiment, the reverse flow directions of the liquid storage tank 10 and the Tesla valve unit 212 are set in the height direction, and the liquid storage tank 10 is located above the flow rate control component 20. The atomized matrix in the liquid storage tank 10 can flow into the flow rate control component 20 under the action of gravity.

[0047] Understandably, in some embodiments, the liquid storage chamber 10 may also be located below the flow rate control component 20, and the entire atomizing component can be flipped over when liquid injection is required. Of course, in some embodiments, the liquid storage chamber 10 and the flow rate control component 20 can also be arranged side by side, and the two angles can be adjusted when liquid injection is required.

[0048] In one embodiment, the flow control assembly 20 may further include a sleeve 22 surrounding the Tesla valve core 21. The sleeve 22 can serve as a support for the entire Tesla valve core 21, facilitating better installation into the atomizing assembly.

[0049] In some embodiments, the Tesla valve core 21 can be made of deformable materials such as silicone or non-deformable materials such as plastic or metal. The Tesla valve core 21 can also consist of two valve bodies joined together along the height direction. After joining, the two valve bodies form corresponding structures such as an inlet 211, an outlet 213, and a Tesla valve unit 212. The two joined valve bodies can be fixed inside the sleeve 22.

[0050] The two valve bodies can be symmetrical, or the inlet 211, outlet 213, Tesla valve unit 212, and other structures can be located on one valve body, while the other valve body is a cover. The specific structural form can be adjusted as needed.

[0051] In one embodiment, the atomizing assembly further includes a seal 50, which is located below the liquid reservoir 30 and the flow control assembly 20 in the height direction. The seal 50 effectively prevents the atomizing matrix from leaking out of the atomizing assembly from below, thereby further avoiding leakage defects.

[0052] In some embodiments, the seal 50 is provided with a mounting hole, the lower end of the sleeve 22 can be inserted into the mounting hole, and the outer wall of the sleeve 22 is in close contact with the inner wall of the mounting hole, thereby preventing the atomized matrix from leaking from the outer wall of the sleeve 22 and further improving the sealing performance.

[0053] In one embodiment, the storage tank 10 directly stores the atomizing matrix, or it can be detachably equipped with a container 11 for storing the atomizing matrix. It is understood that when the storage tank 10 directly stores the atomizing matrix, an injection port can also be provided in the storage tank 10, so that the atomizing matrix can be replenished through the injection port after use. The container 11 can also be detachably installed in the storage tank 10, so that the container 11 can be directly replaced to replenish the atomizing matrix after use.

[0054] In one embodiment, reference Figure 4 The liquid outlet has an outlet end face (unmarked), and the inlet end face and the outlet end face (unmarked) are set at an angle, the angle α being between 60-120°. Thus, after the atomized matrix passes through the Tesla valve unit 212, a vortex zone is formed, which slows down the flow rate. Then, the flow rate is further slowed down by the deflection, and then it is output through the liquid outlet 213.

[0055] In one embodiment, this application also provides an atomizing device, which includes an atomizing component and a power supply component 60. The power supply component 60 supplies power to the atomizing core component 40 of the atomizing component, and the atomizing core component 40 heats the atomizing matrix to produce an aerosol. The atomizing component can be the atomizing component of any of the above embodiments.

[0056] Understandably, the atomizing device may also include a housing 90, a mouthpiece 70, a control circuit 80, etc. The atomizing components, mouthpiece 70, and control circuit 80 can be installed inside the housing 90. The atomizing core assembly 40 may include a heating component 41, a liquid guide 42, and a wire 43. It is electrically connected to the power supply assembly 60 via the wire 43 to access a power source. The liquid guide 42 is connected to the liquid reservoir 30 to receive the atomizing matrix, which is then atomized by the heating component 41 to generate an aerosol, which is then output through the mouthpiece 70 for the user to inhale. Understandably, the atomizing device may include various functions and structures of existing atomizing devices, which will not be elaborated upon here.

[0057] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
