[0002] Existing electronic atomization devices are generally composed of an atomizer and a power supply component, wherein the atomizer includes a liquid reservoir, an atomization component and other components, and the liquid reservoir is connected to the atomization component to provide the atomization component with the atomization matrix required to generate aerosol. In the prior art, the liquid reservoir includes a shell, and an opening is provided on the shell. The opening is sealed with a silicone sealing seat made of silicone material. In order to reuse the liquid reservoir, a liquid injection hole is provided on the shell or the silicone sealing seat to replenish the atomization matrix to the liquid reservoir.

[0003] In the related art, in order to ensure the sealing of the liquid storage of the electronic atomizer, the base is generally made of silicone or other materials to prevent the liquid in the electronic atomizer from leaking out. However, silicone will change due to environmental influences, for example, silicone will expand and contract with heat; in addition, during the assembly process of the base and the liquid reservoir, an interference fit method will be used to squeeze the silicone base, causing the silicone base to deform, and a gap will be generated between the base and the liquid reservoir or between the base and the atomization component, which will cause the liquid stored in the electronic atomizer or the condensate generated to leak out of the gap. To solve this problem, a sealing ring is usually added to the base, but the increase in parts will lead to low assembly efficiency and increased production costs. Utility Model Content

[0032] In order to make the above-mentioned purpose, features and advantages of the present application more obvious and easy to understand, the specific implementation mode of the present application is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present application. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] In the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] The existing liquid storage device includes a shell, a base and a sealing ring. The shell is provided with an opening, the base is made of silicone material, a sealing ring is provided on the base, the base is assembled to the shell from the opening, the sealing ring is deformed between the outer wall of the base and the inner wall of the shell, and the sealing ring with deformation can be used to achieve the sealing and fixation of the shell and the base. It is understandable that during the assembly process, the base made of silicone material will be squeezed and deformed, and at the same time, the sealing ring will be twisted due to continuous friction with the inner wall of the shell or the outer wall of the sealing ring and the base. The twisted sealing ring will produce a slight gap between the shell and the base, causing air to enter the shell, and the atomized matrix will be oxidized if exposed to oxygen for a long time.

[0035] like Figure 2-9 As shown, the present application provides a liquid reservoir, which can be applied to an atomizer and an electronic atomization device having the liquid reservoir. Figure 2-9As shown, the liquid reservoir includes a shell 10, a base 11 made of PP material, and a sealing cover 12, wherein a liquid storage chamber 13 is provided in the shell 10, and an opening is also provided on the shell 10 to communicate with the liquid storage chamber 13; the base 11 is inserted into the opening and has an interference fit with the shell 10 to seal the opening, and a liquid injection hole is provided on the base 11, and the liquid injection hole passes through the base 11 to communicate with the liquid storage chamber 13 and the outside of the shell 10; the sealing cover 12 is detachably provided on the base 11, and a sealing plug 120 is protrudingly provided on the sealing cover 12, and the sealing plug 120 is inserted into the liquid injection hole to seal the liquid injection hole.

[0036] Specifically, PP is a thermoplastic plastic, which is polymerized from propylene monomers, has good chemical stability and heat resistance, is not easily corroded by most solvents and chemicals, and has higher strength and rigidity than silicone materials, that is, better tensile strength and compressive strength, and can resist the effects of external forces to a certain extent. In common electronic atomization devices, the shell 10 of the liquid reservoir is made of high-strength plastic, glass or metal materials, wherein, taking plastic as an example, the shell 10 preferably uses PCTG (amorphous copolyester). It can be understood that the physical strength and rigidity of PCTG are higher than PP. It is known that the shell 10 is hollow, and an opening is provided on the shell 10. The base 11 is inserted into the opening by an interference fit. The base 11 is squeezed by the shell 10 and deformed, and the deformed part is filled into the gap between the base 11 and the inner wall of the shell 10, so that the base 11 can be tightly assembled on the shell 10, and it can also play a good sealing effect.

[0037] In some embodiments, Figure 2-Figure 9 As shown, the shell 10 is roughly barrel-shaped, with an opening at the bottom of the shell 10. The shell 10 extends from the opening into the shell 10 to form a storage cavity for receiving the base 11. The base 11 has an insertion portion that matches the contour of the storage cavity. The size of the insertion portion is slightly larger than the inner diameter of the storage cavity. When the base 11 is inserted into the shell 10 from the opening, it has an interference fit with the shell 10. After the base 11 and the shell 10 are assembled, a sealed liquid storage cavity 13 is formed. When the size of a base 11 is slightly larger than the size of the storage cavity, the two will form a static seal or dynamic seal effect within a certain range after assembly, and at the same time prevent the base 11 from loosening or relative movement in the shell 10. It can be understood that in this embodiment, the shape of the reservoir shell 10 is not limited to a barrel shape, and can also be other shapes, such as a square column shape, a matchbox shape, or even a spherical shape.

[0038] Furthermore, the base 11 is provided with a protrusion 110 on one side close to the inner wall of the housing 10, and a recessed portion cooperating with the protrusion 110 is provided on the inner wall of the housing 10. Figure 8As shown, the base 11 has a side wall, a top surface and a bottom surface, the side wall connects the top surface and the bottom surface, and a protrusion 110 is provided on the side wall of the base 11. When the base 11 is inserted into the liquid storage cavity 13, the protrusion 110 is stuck in the recess to limit the base 11 from moving or rotating in the housing 10. Preferably, two recesses are symmetrically provided on the inner wall of the housing 10, and two corresponding protrusions 110 are provided on the base 11 to enhance the relative rotation resistance between the base 11 and the housing 10.

[0039] In some embodiments, a groove is provided on one side of the base 11 close to the sealing cover 12, the injection hole is provided in the groove, and the sealing cover 12 is installed in the groove to seal the injection hole. Figure 3 As shown, a groove is provided on the bottom surface of the base 11, which is sunken toward the top surface of the base 11. The injection hole passes through the base 11 from the bottom of the groove and is connected to the liquid storage chamber 13 in the housing 10. The sealing plug 120 on the sealing cover 12 is inserted into the injection hole to seal the injection hole. When the atomizing device manufacturer or user injects liquid into the liquid storage chamber 13, the sealing cover 12 can be pulled out first to expose the injection hole, and then the atomizing matrix can be injected into the liquid storage chamber 13 through the injection hole. After the injection is completed, the sealing cover 12 is covered to insert the sealing plug 120 into the injection hole.

[0040] In some embodiments, the sealing cover 12 is made of silicone or PP, and the sealing plug 120 is integrally formed with the sealing cover 12 , so that the user can easily deform the sealing cover 12 by tools or manually, and then lift up the sealing cover 12 .

[0041] It is understandable that compared with the liquid reservoir in the prior art, the above-mentioned liquid reservoir adopts PP material with greater strength and rigidity than silicone material, reduces the use of sealing parts, and the interference fit is more convenient for mechanical or manual assembly, and the production cost is lower.

[0042] Illustratively, the present application also provides a nebulizer, which can atomize the atomization matrix in the liquid reservoir. The nebulizer includes the above-mentioned liquid reservoir and a nebulization component. In some embodiments, the nebulization component can be encapsulated in the liquid reservoir.

[0043] like Figure 2-9As shown, the liquid reservoir of the atomizer 1 includes a shell 10, a base 11 made of PP material, and a sealing cover 12, wherein the shell 10 is roughly cylindrical, has a length in the Z-axis direction, and has a thickness in the radial direction perpendicular to the axial direction, a liquid storage chamber 13 is provided in the shell 10, and a suction nozzle 14 and an opening are also provided on the shell 10, the opening is connected with the liquid storage chamber 13, the base 11 is inserted into the opening and has an interference fit with the shell 10 to seal the opening, a liquid injection hole and an air hole are provided on the base 11, the liquid injection hole passes through the base 11 to connect the liquid storage chamber 13 and the outside of the shell 10, the sealing cover 12 is detachably provided on the base 11, and a sealing plug 120 is protrudingly provided on the sealing cover 12, and the sealing plug 120 is inserted into the liquid injection hole to seal the liquid injection hole.

[0044] The atomizer assembly 15 is encapsulated in the housing 10. The atomizer assembly 15 includes an atomizer tube 150 and a heating element 151 disposed in the atomizer tube 150. One end of the atomizer tube 150 is fixed on the base 11 and communicated with the air hole. The other end of the atomizer tube 150 is connected to the suction nozzle 14. The heating element 151 is disposed in the atomizer tube 150. The heating element 151 heats the atomized matrix in the heating state to generate an aerosol that can be inhaled by the user. The user inhales the aerosol in the atomizer tube 150 through the suction nozzle 14. The external air enters the atomizer tube 150 from the air hole under the action of suction, and flows out of the suction nozzle 14 with the aerosol. It can be understood that the atomizer tube 150 is provided with a liquid guide hole that is connected to the liquid storage chamber 13, and the atomizer assembly 15 obtains the atomized matrix in the liquid storage chamber 13 through the liquid guide hole.

[0045] Furthermore, the atomizing assembly 15 further includes a conductor, which penetrates the bottom of the base 11 and is connected to the heating element 151. The conductor is used to be electrically connected to the power supply unit so that the heating element 151 obtains electrical energy to heat the atomized substrate. It is understandable that the conductor is partially exposed at the bottom of the base 11 and forms a conductive contact to facilitate electrical connection with an external power supply unit.

[0046] In some embodiments, see Figure 3 As shown, the sealing cover 12 on the liquid reservoir is provided with a through hole 122 penetrating the sealing cover 12 , and the through hole 122 is communicated with the air hole to prevent the sealing cover 12 from blocking the air hole.

[0047] Figure 1 As shown, the present application also provides an electronic atomization device, including a power supply device 2 and the above-mentioned atomizer 1, and the atomizer 1 is detachably connected to the power supply device 2. It is known that when the atomizer 1 is connected to the power supply device 2, the conductor electrically connects the heating element 151 to the power supply device 2, and the power supply device 2, as the power supply unit of the atomizer 1, provides the heating element 151 with the electric energy required to heat the atomized matrix.

[0048] In some embodiments, the power supply device 2 includes a battery 21, and also includes a housing 20 encapsulating the battery 21. Figure 6 or Fig. 9 As shown, the power supply device 2 includes a housing 20 and a battery 21 encapsulated in the housing 20. The end of the housing 20 close to the atomizer 1 is recessed into the housing 20 to form a receiving cavity 22 with a depth. The receiving cavity 22 has an opening 23 close to one end of the atomizer 1. The atomizer 1 can be removably plugged into the receiving cavity 22 from the opening 23. In some other embodiments, the atomizer 1 may have the same or similar receiving cavity 22 structure, and the power supply device 2 may be partially plugged into the receiving cavity 22 of the atomizer 1.

[0049] like Figure 6 As shown, an electrode 24 is fixedly arranged at the bottom of the receiving cavity 22, and the electrode 24 is electrically connected to the battery 21. Specifically, one end of the electrode 24 is protrudingly arranged at the bottom of the receiving cavity 22, and the other end of the electrode 24 is electrically connected to the battery 21. Figure 3 As shown, a positioning hole 121 for exposing the conductor is provided on the sealing cover 12. When the atomizer 1 is inserted into the receiving cavity 22, the electrode 24 is inserted into the positioning hole 121 and contacts the conductor. The conductor electrically connects the electrode 23 with the heating element 151 to realize the transmission of electrical energy from the battery 21 to the heating element 151.

[0050] Furthermore, when the atomizer matrix in the liquid reservoir of the atomizer 1 is consumed or either the atomizer 1 or the power supply device 2 is damaged, the user can conveniently pull out the atomizer 1 from the receiving chamber 22 to replace the failed component and continue to use the effective component.

[0051] In some embodiments, the housing 10 of the liquid reservoir in the atomizer 1 is interference-fitted with the receiving cavity 22. Figure 6 As shown, the outer diameter of the housing 10 of the liquid reservoir gradually increases from one end close to the power supply device 2 to the other end. Similarly, in some other embodiments, the inner diameter of the receiving cavity 22 may gradually change from one axial end to the other end to meet the interference fit between the atomizer 1 and the power supply device 2. It is understandable that the housing 10 of the liquid reservoir can also be used as the housing 10 of the atomizer 1.

[0052] In some embodiments, Fig. 9 As shown, a plurality of wedge-shaped tensioning blocks 16 are protrudingly provided on the outer wall of the shell 10 of the liquid reservoir, and the tensioning blocks 16 have a thickness in the radial direction perpendicular to the axial direction of the cylindrical shell 10, and the thickness gradually increases from one end close to the receiving cavity 22 to the other end. When the liquid reservoir is inserted to the bottom of the receiving cavity 22, the tensioning blocks 16 gradually fit to the inner wall of the receiving cavity 22 as the shell 10 gradually penetrates into the receiving cavity 22, so as to achieve an interference fit between the shell 10 and the receiving cavity 22.

[0053] In some embodiments, the power supply device 2 is provided with at least one positioning groove 25, and the housing 10 of the liquid reservoir is provided with a positioning block 17 protruding from the surface of the housing 10, and the positioning block 17 cooperates with the positioning groove 25 to limit the rotation of the atomizer 1 relative to the power supply device 2. Specifically, in order to facilitate quick identification of the plug-in direction of the atomizer 1 and the power supply device 2, as shown in FIG. Fig.10 As shown, at least one positioning groove 25 is provided on the housing 20 of the power supply device 2, and the positioning groove 25 is close to the opening 23 of the accommodating cavity 22, and the positioning block 17 is trapezoidal, and its narrower end is close to the power supply device 2, and the positioning groove 25 is adapted to the contour of the positioning block 17. Furthermore, the positioning groove 25 is a through groove that penetrates the housing 20, and when the positioning block 17 is docked with the positioning groove 25, the surface of the positioning block 17 constitutes a part of the surface of the power supply device 2, so that the atomizer 1 and the power supply device 2 can obtain a nearly complete and smooth surface after being assembled, thereby improving the user's holding experience.
