[0003] The main purpose of this invention is to propose a liquid supply component and atomizer to solve the problem that the liquid supply structure in the prior art is not reusable.

[0004] To achieve the above objectives, in one aspect, this application provides a liquid supply assembly, the liquid supply assembly comprising:

[0005] The first housing has an air intake and an air guide tube that communicates with the air intake and is disposed within the first housing. An open cavity is formed between the outer wall of the air guide tube and the inner wall of the first housing.

[0006] A sealing cap is connected to the first housing and closes the cavity to form a closed first liquid storage cavity. The sealing cap is provided with a liquid outlet and a mounting hole. A sealing block is provided at the liquid outlet. The sealing block can deform under the action of external force and at least partially detach from the liquid outlet.

[0007] The air guide tube is at least partially interference-fitted into the mounting hole to form a sealed connection with the sealing cap.

[0008] It is understood that in the above embodiments, the liquid supply component can not only be connected to the atomizing component as a nozzle, but also provide additional atomizing liquid to the atomizing component, and the liquid supply component can be reused.

[0009] In some embodiments, the sealing cap and the inner wall of the first housing enclose a receiving cavity on the side opposite to the first liquid storage cavity.

[0010] Furthermore, the receiving cavity has a slot on its groove wall.

[0011] In some embodiments, the sealing block includes a deformable portion and a movable portion connected together, the deformable portion being connected to a sealing cap, and the movable portion covering the liquid outlet.

[0012] In some embodiments, the cross-section of the sealing block on the side near the liquid outlet is smaller than the cross-section on the side away from the liquid outlet.

[0013] In some embodiments, the sealing cap has a slit that defines the closure block within the sealing cap.

[0014] Furthermore, the width of the aforementioned cut is between 0.1 and 0.7 mm.

[0015] On the other hand, this application also provides an atomizer, which includes an atomizing component and a liquid supply component as described in any of the above claims.

[0038] This application provides a liquid supply assembly having a housing and a sealing cap, the sealing cap being connected to the housing and defining a reservoir within the housing for storing atomizing liquid (atomizing matrix, e-liquid). It is understood that in some embodiments, the liquid supply assembly can be part of an atomizer, with its housing being part of the atomizer housing; that is, the housing of the liquid supply assembly serves as a first housing, and other parts of the atomizer housing serve as a second, third, or Nth housing.

[0039] In some embodiments, such as Figure 1-12As shown, the outer shell of the liquid supply assembly serves as the first housing 10 of the atomizer. The first housing 10 has a proximal end for the user to inhale aerosol or atomized vapor, and a distal end away from the proximal end. The first housing 10 has an air inlet 100 on the proximal surface. An air guide tube 102 is provided inside the first housing 10. The air guide tube 102 internally defines an air passage 1020 that allows gas to pass through the liquid supply assembly. The air outlet end of the air guide tube 102 is connected to the air inlet 100. The air inlet end of the air guide tube 102 extends distally to form an air inlet 101 of the liquid supply assembly. An open cavity is formed between the outer wall of the air guide tube 102 and the inner wall of the first housing 10 on the distal side.

[0040] like Figure 1 As shown, at least a portion of the edge or sidewall of the sealing cap 11 extends into the cavity and connects with the inner wall of the first housing 10 at the opening of the cavity. The sealing cap 11 is used to connect with the first housing 10 and seal the cavity to form a closed first liquid storage chamber 103. After the sealing cap 11 is connected to the first housing 10, at least a portion of the air guide tube 102 is interference-fitted into the mounting hole 110 to seal against the sealing cap 11. This prevents the e-liquid in the first liquid storage chamber 103 from directly entering the air guide tube 102 and causing leakage.

[0041] It is understood that in the above embodiments, the liquid supply component can be packaged and transported independently. The liquid supply component can not only be connected to the atomizing component 20 as the mouthpiece of the atomizer 1, but also provide additional atomizing liquid to the atomizing component 20. Moreover, the liquid supply component can be reused.

[0042] In some embodiments, the sealing cap 11 and the inner wall of the first housing 10 enclose a receiving cavity 105 on the side opposite to the first liquid storage cavity 103. Specifically, the sealing cap 11 is installed in the cavity and divides the cavity into a closed first liquid storage cavity 103 and a semi-closed receiving cavity 105, the receiving cavity 105 being used to connect and form with other functional components of the atomizer 1.

[0043] Furthermore, a slot 104 is provided on the groove wall of the receiving cavity 105. For example... Figure 2 As shown, the slot 104 is a through slot that can engage with the connecting protrusions on other functional components.

[0044] In some embodiments, the sealing cap 11 is provided with a liquid outlet 111 and a mounting hole 110, and a sealing block 112 is provided at the liquid outlet 111. The sealing block 112 can deform under the action of external force and at least partially detach from the liquid outlet 111.

[0045] like Figures 3-4As shown, the sealing block 112 includes a deformable part 1120 and a movable part 1121 connected together. The deformable part 1120 is connected to the sealing cap 11, and the movable part 1121 covers the liquid outlet 111. The movable part 1121 can act as a bearing for external forces. Under the action of external forces, the movable part 1121 is forced to move into the first liquid storage chamber 103. The deformable part 1120 deforms to allow the movable part 1121 to move into the first liquid storage chamber 103, thereby opening the liquid outlet 111 and allowing e-liquid to flow out from the liquid outlet 111.

[0046] The sealing block 112 is preferably made of silicone or rubber, which can deform under stress and return to its original state after the external force is removed. Furthermore, the sealing cap 11 and the sealing block 112 can be made of the same material and can be integrally molded. It is foreseeable that the sealing cap 11 can be interference-fitted with the first housing 10 to provide better sealing of the first liquid storage chamber 103. For example, in some embodiments, the sealing cap 11 has a slit 113, which cuts a sealing block 112 at a position corresponding to the liquid outlet 111, partially away from the sealing cap 11. One side of the sealing block 112 is connected to the sealing cap 11. The presence of the slit 113 makes it easier for the sealing block 112 to detach from the liquid outlet 111 under the action of external force.

[0047] In some embodiments, the cross-section of the sealing block 112 near the liquid outlet 111 is smaller than the cross-section away from the liquid outlet 111. Alternatively, the sealing block 112 has a top end facing the interior of the first liquid storage chamber 103 and a bottom end away from the top end, wherein the cross-sectional area of ​​the top end is larger than the cross-sectional area of ​​the bottom end, or the cross-sectional area of ​​the sealing block 112 gradually decreases from the top end to the bottom end, with the smaller bottom end serving a guiding function. When the sealing block 112 recovers from deformation, it can be guided into the liquid outlet 111 through the bottom end, and after gradually penetrating the liquid outlet 111, it forms a tight fit or interference fit with the liquid outlet 111. Figure 5 As shown, the sealing block 112 is divided into a lower part and an upper part according to the size of its cross-sectional area. The upper part has a larger cross-sectional area than the lower part. In use, the lower part is inserted into the liquid outlet 111 to form a clearance fit, and the upper part forms an interference fit with the liquid outlet 111.

[0048] Furthermore, the width of the aforementioned slit 113 is between 0.1 and 0.7 mm. Under the influence of the surface tension of the atomizing liquid, the atomizing liquid is unlikely to leak through the slit 113.

[0049] On the other hand, this application also provides an atomizer, see [link to application]. Figures 6-12As shown, the atomizer 1 includes a liquid supply component and an atomizing component 20 as described in any of the above embodiments. The atomizing component 20 has a protruding arm 221. After the atomizing component 20 is connected to the liquid supply component, the arm 221 lifts the sealing block 112, so that the first liquid storage chamber 103 is in liquid communication with the atomizing component 20, and the atomizing liquid stored in the first liquid storage chamber 103 is supplied to the atomizing component 20.

[0050] Specifically, the atomizing component 20 includes a second housing 21, a base 22, an atomizing tube 23, and an atomizing core 24. One end of the second housing 21 is connected to the first housing 10. The base 22 is detachably connected to the other end of the second housing 21 and defines an installation cavity between the base and the second housing 21. The atomizing tube 23 is disposed in the installation cavity. The second housing 21, the base 22, and the atomizing tube 23 together enclose a second liquid storage cavity 25. The atomizing tube 23 is provided with a liquid inlet hole 230 communicating with the second liquid storage cavity 25. The atomizing core 24 is fixed inside the atomizing tube 23.

[0051] like Figure 9 As shown, the second housing 21 and the base 22 enclose a mounting cavity. The second housing 21 has a liquid inlet 212 and an air outlet 211 on the side near the first housing 10. The air inlet end of the atomizing tube 23 is fixed to the base 22 within the mounting cavity, and the air outlet end of the atomizing tube 23 communicates with the air outlet 211. The second housing 21, the atomizing tube 23, and the base 22 together form a second liquid storage cavity 25, and the liquid inlet 230 communicates with the second liquid storage cavity 25. The positions of the liquid inlet 212 and the liquid outlet 111 correspond, and the arm 221 extends from the second liquid storage cavity 25 and passes through the liquid inlet 212. Figure 12 As shown, after the first housing 10 is connected to the second housing 21, the arm 221 lifts the sealing block 112, pushing the sealing block 112 to deform or detach from the liquid outlet 111. The atomized liquid flows into the second liquid outlet 25 from the first liquid storage chamber 103, and then flows into the atomizing tube 23 through the liquid inlet 230 and is heated and atomized by the atomizing core 24.

[0052] The base 22 is also provided with an air inlet 223 that penetrates the base 22, and the air inlet end of the atomizing tube 23 is inserted into the air inlet 223 and connected to the base 22.

[0053] like Figure 9 As shown, the base 22 extends longitudinally from the second liquid storage chamber 25 to form an arm 221 that passes through the liquid inlet 212. The cross-sectional area of ​​the arm 221 gradually decreases from the base 22 to the end, so that the atomized liquid can enter the second liquid storage chamber 25 through the liquid inlet 212. The arm 221 can also serve as a liquid guiding component to guide the atomized liquid into the second liquid storage chamber 25.

[0054] In some embodiments, the second housing 21 is provided with a buckle 213, and the base 22 is provided with a first latching protrusion 210 that engages with the buckle 213. For example... Figure 10As shown, the base and the second housing 21 are detachably connected so that the user can replace or clean the atomizing tube 23 or the atomizing core 24 as needed.

[0055] Furthermore, the second housing 21 is provided with a second latching protrusion 222, which is used to engage with the latching groove 104 on the first housing 10.

[0056] Specifically, the first housing 10 has a receiving cavity 105, and the second housing 21 is at least partially housed within the receiving cavity 105. The surfaces of the first housing 10 and the second housing 21 are joined to form an integral atomizer 1. Furthermore, after the first housing 10 and the second housing 21 are joined, the air guide tube 102 is in gas communication with the atomizing tube 23, and the aerosol formed by the atomization of the atomizing component 20 is discharged from the air inlet 100 through the air guide tube 102.
