Description

Technical Field

[0001] This application relates to the field of atomizing device technology, and more particularly to a liquid supply structure and an electronic atomizing device. Background Technology

[0002] Current electronic atomizing devices often use a direct connection between the atomizer and the reservoir to supply e-liquid. Under conditions of significant differences in the external environment, this method can easily lead to overfilling of the reservoir cotton inside the atomizer. When the reservoir cotton exceeds its storage limit, leakage may occur.

[0003] Therefore, solutions have emerged that use piezoelectric pumps to quantitatively deliver the atomized liquid from the reservoir to the atomizer's storage cotton. This solution allows the piezoelectric pump to replenish the liquid exactly as it is consumed by the atomizer, avoiding leakage caused by changes in the external environment when the atomizer and reservoir are directly connected. However, current electronic atomization devices that use piezoelectric pumps to quantitatively deliver the atomized liquid from the reservoir to the atomizer suffer from the problem of inconvenient replenishment of the liquid after it is depleted.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0026] In this specification, references to "one embodiment," "some embodiments," or "embodiment" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.

[0027] Current electronic atomizing devices often use a direct connection between the atomizer and the reservoir to supply e-liquid. Under conditions of significant differences in the external environment, this method can lead to overfilling of the reservoir cotton inside the atomizer, which can cause leakage if the cotton exceeds its storage limit.

[0028] Therefore, solutions have emerged that use piezoelectric pumps to quantitatively deliver the atomized liquid from the reservoir to the atomizer's storage cotton. This solution allows the piezoelectric pump to replenish the liquid as needed. However, current electronic atomization devices that use piezoelectric pumps to quantitatively deliver the atomized liquid from the reservoir have the problem of inconvenient replenishment once the liquid in the reservoir is depleted.

[0029] In view of this, this application provides a liquid supply structure and an electronic atomizing device. Since the main component includes an atomizer, and the split component is detachably connected to the main component, the split component includes a liquid storage tank with a storage cavity for storing atomized liquid. Furthermore, at least one of the main component and the split component is detachably connected to a power pump. The power pump has an input end and an output end, with the input end connected to the liquid storage tank and the output end connected to the atomizer. Therefore, after the atomized liquid in the liquid storage tank is consumed, the split component can be directly disassembled from the main component, and then atomized liquid can be injected into the storage cavity in the liquid storage tank of the split component to replenish the atomized liquid. Then, the split component can be reconnected to the main component so that the input end is connected to the liquid storage tank and the output end is connected to the atomizer. The operation is simple and convenient.

[0030] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0031] Please refer to Figures 1 to 5 , Figure 1 This is a schematic diagram of the structure of the electronic atomizing device 100 in one embodiment of this application. Figure 2 yes Figure 1 The diagram shows an exploded view of the electronic atomizing device 100. Figure 3 yes Figure 1 The top view of the electronic atomizing device 100 shown is shown. Figure 4 yes Figure 3 The electronic atomizing device 100 shown is a cross-sectional view along the mm direction. Figure 5 yes Figure 1 A magnified view of a portion of point A in the middle.

[0032] In a first aspect, embodiments of this application provide a liquid supply structure, including a main component 10, a split component 20, and a power pump 30.

[0033] The main component 10 includes an atomizer 11, which can be used to heat and atomize the atomizing liquid.

[0034] The atomizer 11 may include an atomizing core 111 and a reservoir cotton 112, in some examples, the reservoir cotton 112 is fitted onto the atomizing core 111.

[0035] The split component 20 is detachably connected to the main component 10. Please refer to [link / reference]. Figure 4 The split component 20 includes a liquid storage tank 21, which has a liquid storage cavity 2101 for storing atomizing liquid.

[0036] In some examples, the separate component 20 and the main component 10 can be detachably connected by means of magnetic attraction, snap-fit, screw connection, bolt connection or buckle connection.

[0037] At least one of the main component 10 and the separate component 20 is detachably connected to the power pump 30, see [link to relevant documentation]. Figure 5 The power pump 30 has an input end 31 and an output end 32. The input end 31 is connected to the liquid storage tank 21, and the output end 32 is connected to the atomizer 11.

[0038] The power pump 30 can be a piezoelectric pump or a micro pump, etc. For example, a piezoelectric pump has a square structure with a ribbon cable on top for connection to a control board to form power supply and signal control. The liquid inside the piezoelectric pump flows in one direction only; reverse flow is blocked. The working process of the piezoelectric pump is as follows: when an AC voltage is applied to the piezoelectric vibrator, the vibrator is compressed and bent radially under the action of the electric field. This periodic deformation causes a change in the volume of the pump chamber. When the piezoelectric vibrator bends forward, the pump chamber volume increases, the internal pressure decreases, the pump valve opens, and the atomized liquid enters the pump chamber; when the piezoelectric vibrator bends in the reverse direction, the pump chamber volume decreases, the internal pressure increases, the pump valve closes, and the atomized liquid in the pump chamber is discharged.

[0039] It is understood that the liquid supply structure provided in this application embodiment can utilize the characteristics of the power pump 30 to deliver atomizing liquid to the atomizing core 111 of the atomizer 11 in a timed and quantitative manner. When the power pump 30 is working, the atomizing liquid enters from the liquid storage chamber 21 above the liquid storage cotton 112 of the atomizer 11 and is quickly absorbed by the liquid storage cotton 112. When the liquid storage cotton 112 absorbs to a certain extent, it can conduct the atomizing liquid to the atomizing core 111 in the center, thus supplying atomizing liquid to the atomizing core 111. This ensures that the liquid storage cotton 112 of the atomizer 11 will not be oversaturated with the atomizing liquid, solving the leakage phenomenon caused by external environmental factors.

[0040] In some examples, at least one of the main component 10 and the separate component 20 can be detachably connected to the power pump 30 by means of magnetic connection, snap-fit, screw connection, bolt connection or snap-fit ​​connection.

[0041] Wherein, at least one of the main component 10 and the separate component 20 may be detachably connected to the power pump 30 as follows: The main body component 10 is detachably connected to the power pump 30, and the split component 20 is connected to the power pump 30. After the split component 20 is separated from the main body component 10, the input end 31 is connected to the liquid storage tank 21, and the output end 32 is not connected to the atomizer 11. When the split component 20 is connected to the main body component 10, the input end 31 is connected to the liquid storage tank 21, and the output end 32 is connected to the atomizer 11.

[0042] Alternatively, the main component 10 is connected to the power pump 30, and the split component 20 is detachably connected to the power pump 30. After the split component 20 is separated from the main component 10, the input end 31 is not connected to the liquid storage tank 21, and the output end 32 is connected to the atomizer 11. When the split component 20 is connected to the main component 10, the input end 31 is connected to the liquid storage tank 21, and the output end 32 is connected to the atomizer 11.

[0043] Alternatively, the main component 10 can be detachably connected to the power pump 30, and the split component 20 can be detachably connected to the power pump 30. After the split component 20 is separated from the main component 10, the input end 31 is not connected to the liquid storage tank 21, and the output end 32 is not connected to the atomizer 11. When the split component 20 is connected to the main component 10, the input end 31 is connected to the liquid storage tank 21, and the output end 32 is connected to the atomizer 11.

[0044] As can be seen from the above, the liquid supply structure provided in this application embodiment includes an atomizer 11 in the main component 10, and a detachable component 20 connected to the main component 10. The detachable component 20 includes a liquid storage tank 21, which has a storage cavity 2101 for storing atomized liquid. At least one of the main component 10 and the detachable component 20 is detachably connected to a power pump 30. The power pump 30 has an input end 31 and an output end 32, and the input end 31 is connected to the liquid storage tank 21. The output end 32 is connected to the atomizer 11. Therefore, after the atomizing liquid in the storage tank 21 is consumed, the split component 20 can be directly disassembled from the main component 10. Then, atomizing liquid can be injected into the storage chamber 2101 in the storage tank 21 of the split component 20 to replenish the atomizing liquid. Then, the split component 20 can be connected to the main component 10, so that the input end 31 is connected to the storage tank 21 and the output end 32 is connected to the atomizer 11. The operation is simple and convenient.

[0045] It should be noted that multiple split components 20 can be provided as spare parts (the liquid storage chamber 2101 in its liquid storage tank 21 has been pre-filled with atomizing liquid). After the split component 20 is disassembled from the main component 10, another split component 20 can be directly connected to the main component 10.

[0046] Please refer to Figures 1 to 5In some embodiments, the power pump 30 is connected to the main body component 10, and the liquid storage tank 21 is detachably connected to the power pump 30.

[0047] By adopting the above solution, it is only necessary to disassemble the split component 20 from the main component 10, then inject atomizing liquid into the liquid storage chamber 2101 in the liquid storage tank 21 of the split component 20 to replenish the atomizing liquid, and then connect the split component 20 to the main component 10 so that the input end 31 is connected to the liquid storage tank 21. There is no need to disassemble the power pump 30, making the operation simpler and more convenient.

[0048] Optionally, the liquid storage tank 21 is provided with a liquid outlet 2102 that communicates with the liquid storage cavity 2101, and the input end 31 is detachably inserted into the liquid outlet 2102.

[0049] With this configuration, the input end 31 can be directly inserted into the liquid outlet 2102 to connect the liquid storage tank 21 with the power pump 30, and to make the input end 31 connected to the liquid storage tank 21, which is simple and convenient to operate.

[0050] Please refer to this as well. Figure 6 and Figure 7 , Figure 6 yes Figure 1 The diagram shows the structure of the separate component 20 in the electronic atomizing device 100. Figure 7 yes Figure 6 The exploded structural diagram of the split component 20 shown.

[0051] As one possible implementation, the split component 20 includes a plug 22 that is detachably inserted into the liquid outlet 2102.

[0052] By adopting the above solution, when it is not necessary to connect the separate component 20 to the main component 10, the liquid outlet 2102 can be sealed by inserting the sealing component 22 into the liquid outlet 2102. When it is necessary to connect the separate component 20 to the main component 10, the sealing component 22 can be removed from the liquid outlet 2102 so that the input end 31 can be inserted into the liquid outlet 2102.

[0053] It should be noted that the separate component 20 does not need to be connected to the main component 10 during transportation. The sealing element 22 can be removed from the outlet hole 2102 by directly taking it out of the outlet hole 2102 or by moving the sealing element 22 into the storage chamber 2101. The sealing element 22 can be configured as a columnar structure.

[0054] Optionally, the liquid storage tank 21 includes a resilient seal 211 that defines an outlet hole 2102.

[0055] This design allows the sealing component 22 to achieve better sealing performance against the liquid outlet 2102.

[0056] It should be noted that the material of the elastic seal 211 can be silicone or rubber, etc. The liquid storage tank 21 may be provided with a mounting hole, and the elastic seal 211 is housed in the mounting hole.

[0057] Please refer to Figures 3 to 7 In some embodiments, the liquid storage tank 21 is provided with an injection hole 2103 that communicates with the liquid storage cavity 2101; the split component 20 also includes an injection assembly 23 and a limiting member 24. The injection assembly 23 is connected to the injection hole 2103, and the limiting member 24 is detachably connected to the liquid storage tank 21. Part of the limiting member 24 abuts against the injection assembly 23 to restrict the injection assembly 23 from moving away from the injection hole 2103.

[0058] By adopting the above solution, the liquid injection assembly 23 can be restricted from moving in a direction away from the liquid injection hole 2103 by partially limiting the limiting member 24 abutting against it, thereby preventing the liquid injection assembly 23 from becoming loose or falling off.

[0059] It should be noted that the liquid injection assembly 23 may include a one-way valve 231 and a sealing silicone 232, and a portion of the limiting member 24 abuts against the one-way valve 231. The limiting member 24 and the liquid storage tank 21 can be detachably connected by means of magnetic attraction, snap-fit, screw connection, bolt connection or buckle connection.

[0060] Understandably, the limiting component 24 can also be used as a decorative component.

[0061] As one possible implementation, the outer surface of the liquid storage tank 21 is provided with a first connecting part 2104; the limiting member 24 is sleeved on the liquid storage tank 21, and the limiting member 24 is provided with a second connecting part 241, and the first connecting part 2104 and the second connecting part 241 are detachably connected.

[0062] By adopting the above solution, the limiting component 24 and the liquid storage tank 21 can be detachably connected relatively easily.

[0063] It should be noted that the first connecting part 2104 can be configured as a connecting post, and the second connecting part 241 can be configured as a connecting hole. Alternatively, the second connecting part 241 can be configured as a connecting post, and the first connecting part 2104 can be configured as a connecting hole. Multiple first connecting parts 2104 and second connecting parts 241 can be provided, and each part corresponds to the other.

[0064] Please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7In some embodiments, the main body component 10 includes a main housing 12, an atomizer 11 is disposed within the main housing 12, the main housing 12 is provided with a receiving groove 121, and at least a portion of the separate component 20 is received within the receiving groove 121.

[0065] By adopting the above solution, the position of the split component 20 can be defined by the receiving groove 121.

[0066] It should be noted that the power pump 30 can be connected to the main housing 12, and part of the liquid storage tank 21 is housed in the receiving tank 121.

[0067] Optionally, the main housing 12 is provided with a retaining part 101, which is located on the bottom wall and / or side wall of the receiving groove 121. The split component 20 includes a snap-fit ​​part 201, which is detachably snap-fitted with the retaining part 101.

[0068] This design allows for a relatively convenient detachable connection between the main housing 12 and the separate component 20.

[0069] It should be noted that the holding part 101 can be configured as a hook, and the engaging part 201 can be configured as a slot. Alternatively, the holding part 101 can be configured as a slot, and the engaging part 201 can be configured as a hook. Multiple engaging parts 201 and holding parts 101 can be provided, and they are configured in a one-to-one correspondence. The engaging part 201 can be provided in the liquid storage tank 21.

[0070] Optionally, the main housing 12 is provided with a positioning part 102, which is located on the bottom wall and / or side wall of the receiving groove 121. The split component 20 includes a mating part 202, which mates with the positioning part 102 to limit the relative position of the main body and the split component 20 in the connection direction, which is perpendicular to the depth direction of the receiving groove 121.

[0071] With this configuration, the mating part 202 can cooperate with the positioning part 102 to limit the relative position of the main body and the split part 20 in the connection direction perpendicular to the depth direction of the receiving groove 121.

[0072] It should be noted that the mating part 202 can be recessed, and the positioning part 102 can be protruding. Alternatively, the mating part 202 can be protruding, and the positioning part 102 can be recessed. Multiple mating parts 202 and positioning parts 102 can be provided, and they are arranged in a one-to-one correspondence. The mating part 202 can be provided in the liquid storage tank 21.

[0073] For example, the mating part 202 is set as a recess, and the positioning part 102 is set as a protrusion.

[0074] Optionally, the power pump 30 is disposed inside the main housing 12, and the input end 31 extends to the outside of the positioning part 102.

[0075] This configuration allows for a more compact structure of the main component 10 and the power pump 30.

[0076] It is understood that the liquid outlet 2102 can be located at the bottom of the mating part 202, and the input end 31 can be detachably inserted into the liquid outlet 2102.

[0077] Optionally, the split component 20 includes a stop portion 203, and the bottom wall of the receiving groove 121 is slidably engaged with the stop portion 203.

[0078] With this configuration, when the separate component 20 is placed in the receiving groove 121, the stop part 203 can restrict the position of the entire separate component 20 in the receiving groove 121.

[0079] It should be noted that the stop part 203 can be configured as a protrusion, and multiple stop parts 203 can be provided. The stop part 203 can be provided in the liquid storage tank 21.

The split component 20 includes a liquid storage tank 21 with a liquid storage cavity 2101 for storing atomizing liquid. At least one of the main component 10 and the split component 20 is detachably connected to a power pump 30. The power pump 30 has an input end 31 and an output end 32. The input end 31 is connected to the liquid storage tank 21, and the output end 32 is connected to the atomizer 11. Therefore, after the atomizing liquid in the liquid storage tank 21 is consumed, the split component 20 can be directly disassembled from the main component 10, and then atomizing liquid can be injected into the liquid storage cavity 2101 in the liquid storage tank 21 of the split component 20 to replenish the atomizing liquid.
