[0034] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0035] The disclosure below provides many different embodiments or examples for implementing different structures of the embodiments of the present application. In order to simplify the disclosure of the embodiments of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the embodiments of the present application. In addition, the embodiments of the present application may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0036] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0037] In order to solve the problems in the prior art, the present application provides an atomizer seat and an electronic atomizer, which can effectively improve the sealing between the needle and the liquid storage assembly, avoid leakage of the atomized liquid, and cause waste and contamination and damage to internal components.

[0038] like Figure 1-3As shown, an embodiment of the present application provides an atomizer seat, including a support seat 1 and a needle 2 arranged on the support seat 1, the needle 2 has a sealing section 21 connected to the support seat 1, and the outer diameter of the sealing section 21 is gradually expanded along the axial direction of the needle 2 toward the support seat 1, and the sealing section 21 is used to abut the sealing plug 31 of the liquid storage component 3.

[0039] In the present application, after the needle 2 penetrates the liquid storage component 3, the sealing section 21 of the needle 2 abuts against the sealing plug 31 of the liquid storage component 3, and the sealing section 21 adopts a gradually expanding design to form a wedge-shaped fit with the sealing plug 31 to increase the contact pressure. Compared with the traditional straight-cylindrical needle 2, the gradually expanding design greatly improves the sealing reliability, avoids the leakage of the atomized liquid and causes waste and pollution and damage to internal components.

[0040] In the related art, the needles 2 on the current atomizer seats all use straight cylindrical needles 2. After piercing the sealing plug 31 of the liquid storage assembly 3, the needles 2 are sealed only by the axial outer surface of the needle 2 and the sealing plug 31. The sealing effect is poor, especially when the needle 2 tilts during use, it is easy for the atomized liquid to leak between the needle 2 and the sealing plug 31, resulting in waste of the atomized liquid and contamination and damage to internal components.

[0041] In the embodiment of the present application, the sealing section 21 of the needle 2 employs a tapered, gradually expanding structure. When the needle 2 penetrates the sealing plug 31 of the liquid reservoir assembly 3, the gradually expanding section and the sealing plug 31 are squeezed and deformed. The radial pressure generated by this deformation forms a sealing surface, preventing liquid leakage. The gradually expanding design of the sealing section 21 provides a better sealing effect, preventing atomized liquid leakage. The gradually expanding structure creates a wedge-shaped fit between the needle 2 and the sealing plug 31, increasing contact pressure. Compared to traditional straight-cylinder needles 2, the gradually expanding design significantly improves sealing reliability. It is suitable for portable electronic atomizers and solves the problem of liquid leakage.

[0042] The gradual expansion angle of the sealing section 21 can be optimized according to actual needs.

[0043] Optionally, a stepped gradually expanding structure may be adopted, which is easy to process and has multiple seals.

[0044] Optionally, an annular protrusion may be provided on the surface of the sealing section 21 to further enhance the sealing effect.

[0045] In some embodiments, the needle 2 also includes a straight section 22 connected to the sealing section 21. The straight section 22 is used to accommodate the ceramic column 41 of the atomization assembly 4. The outer diameter of the straight section 22 is equal to the minimum outer diameter of the sealing section 21. The straight section 22 is provided with a liquid inlet 221 for the atomized liquid to enter.

[0046] In this application, the straight section 22 provides a stable installation space for the ceramic column 41; the outer diameter is equal to the minimum outer diameter of the sealing section 21, achieving a smooth transition; the design of the liquid inlet 221 ensures that the atomized liquid supply channel is unobstructed, the overall structure is compact, and the assembly is convenient.

[0047] Specifically, the liquid inlet 221 can be arranged radially or obliquely; the straight section 22 and the sealing section 21 are integrally formed to ensure processing accuracy and achieve reliable positioning.

[0048] Optionally, the straight section 22 may be designed with multiple liquid inlet holes 221 to improve liquid supply efficiency.

[0049] In some embodiments, the needle 2 also includes: a piercing section 23, which is arranged at a section of the needle 2 away from the support seat 1, and the piercing section 23 is used to pierce the sealing plug 31 of the liquid storage component 3, and the outer diameter of the piercing section 23 is smaller than the outer diameter of the straight tube section 22; and a transition section 24, the two ends of the transition section 24 are respectively connected to the piercing section 23 and the straight tube section 22, and the outer diameter of the transition section 24 is gradually expanded from the piercing section 23 to the straight tube section 22.

[0050] In the present application, the piercing section 23 is small and convenient for penetrating the sealing plug 31, the transition section 24 is gradually designed to reduce the insertion resistance, the structural optimization reduces the risk of damage to the sealing plug 31, and improves the reliability of the assembly process.

[0051] Specifically, the piercing section 23 adopts a conical tip or a cut-surface tip, and the transition section 24 adopts a smooth transition.

[0052] In another embodiment, the needle 2 further includes a piercing section 23 connected to an end of the straight section 22 away from the sealing section 21 , and the outer diameter of the piercing section 23 is gradually expanded toward the straight section 22 .

[0053] The present application provides an alternative insertion structure design. The gradually expanding insertion section 23 is conducive to reducing the insertion resistance, simplifying the overall structure of the needle 2, facilitating processing and manufacturing, and reducing costs.

[0054] Specifically, the piercing section 23 is directly connected to the straight section 22, adopting a single gradually expanding angle design, without the need for an additional transition section 24 structure, and the surface treatment ensures a smooth transition

[0055] Optionally, a multi-stage gradually expanding angle design may be adopted.

[0056] In some embodiments, a first cavity communicating with the needle 2 is provided inside the support base 1 , and the first cavity is used to accommodate the ceramic base 42 of the atomization assembly 4 . An air inlet 11 communicating with the first cavity is provided on the side wall of the support base 1 .

[0057] In this application, the air intake is assisted by the air inlet 11, balancing the air pressure inside and outside the liquid storage component 3, so that the atomized liquid in the liquid storage component 3 can be discharged more smoothly, thereby ensuring that the atomization is not easy to be mushy, the mist is more moist, and the taste is better. The atomizer component 4 is stably installed, the air inlet channel is ensured to be unobstructed, the air flow path is optimized, and the atomization effect is improved.

[0058] Specifically, the size of the first cavity matches the ceramic seat 42 .

[0059] In some embodiments, the atomizer seat further includes a base 5 connected to the support seat 1 , and a second cavity is provided inside the base 5 , and the second cavity is used to accommodate the oil absorption assembly 6 .

[0060] In this application, the leakage and accumulation of atomized liquid are prevented, the atomized liquid is prevented from contacting electrical connection components, the service life of the product is extended, and the product safety is improved.

[0061] After the needle 2 of the atomizer seat penetrates the liquid storage component 3, the sealing section 21 of the needle 2 abuts against the sealing plug 31 of the liquid storage component 3. The sealing section 21 adopts a gradually expanding design, forming a wedge-shaped fit with the sealing plug 31 to increase the contact pressure. Compared with the traditional straight-cylinder needle 2, the gradually expanding design greatly improves the sealing reliability, avoids the waste caused by leakage of the atomized liquid and avoids pollution and damage to internal components.

[0062] like Figure 4-8 As shown, an embodiment of the present application provides an electronic atomizer, comprising: a shell 7 and a liquid storage component 3 and an atomization component 4 arranged in the shell 7; and the above-mentioned atomization seat, the atomization seat is arranged in the shell 7, and the atomization seat is used to support the atomization component 4 and the liquid storage component 3.

[0063] In the present application, the housing 7 is used to accommodate the liquid storage assembly 3 and the atomizer assembly 4. The atomizer seat is disposed within the housing 7 and cooperates with the housing 7 as a carrier for the liquid storage assembly 3 and the atomizer assembly 4, ensuring that the liquid storage assembly 3 can be accurately and effectively connected to the atomizer assembly 4, so that the atomized liquid in the liquid storage assembly 3 can be guided to the atomizer assembly 4 for atomization. Specifically, a suction nozzle is provided at one end of the housing 7 away from the atomizer assembly 4. The power of the suction nozzle generates negative pressure, thereby allowing external gas to enter the housing 7 and be inhaled through the suction nozzle together with the generated aerosol.

[0064] In some embodiments, the atomizer seat includes a support seat 1 and a base 5 connected to the support seat 1. A first cavity is provided in the support seat 1, and the first cavity is used to accommodate the ceramic seat 42 of the atomizer assembly 4. A second cavity connected to the first cavity is provided in the base 5. The electronic atomizer also includes an oil absorption assembly 6 arranged in the second cavity.

[0065] In this application, a complete liquid circulation and collection system is formed to prevent the atomized liquid from leaking into electrical components, improve product safety, and facilitate maintenance and cleaning.

[0066] In some embodiments, the atomization assembly 4 includes a first lead 43 and a second lead 44 electrically connected to the ceramic seat 42; the oil absorption assembly 6 includes: a porous ceramic 61, the porous ceramic 61 is provided with a through-hole 611 for the first lead 43 to pass through; and a flexible protective ring 62, which is sleeved on the outer periphery of the porous ceramic 61; wherein the second lead 44 is clamped between the flexible protective ring 62 and the base 5.

[0067] In this application, reliable protection of electrical connections is achieved, short circuits caused by liquid infiltration are prevented, the assembly process is simplified, and the product life is increased.

[0068] Specifically, first lead 43 passes through perforation 611 of porous ceramic 61 and through oil absorbing assembly 6, while second lead 44 bypasses oil absorbing assembly 6 through the gap between oil absorbing assembly 6 and base 5. This creates a relatively large distance between first lead 43 and second lead 44, effectively isolating them and preventing a positive-to-negative short circuit between them. Furthermore, flexible protective ring 62, made of silicone, clamps second lead 44, facilitating assembly and securing without damaging it.

[0069] In some embodiments, a notch 612 is provided on the porous ceramic 61 for accommodating the second lead 44 .

[0070] In the present application, the second lead 44 is avoided by the notch 612 on the porous ceramic 61, which can prevent the second lead 44 from squeezing the hard porous ceramic 61 and causing cracking, powder loss, and other undesirable phenomena of the porous ceramic 61. At the same time, the second lead 44 can be protected from damage caused by the hard porous ceramic 61.

[0071] In some embodiments, the shell 7 includes an outer shell 71 and a bottom shell 72 connected to one end of the outer shell 71. The bottom shell 72 is used to support the base 5. The bottom shell 72 has a connecting portion 721. The connecting portion 721 is arranged between the outer shell and the base 5, and the connecting portion is interference fit with the outer shell and the base 5.

[0072] In the present application, the connecting portion 721 is an annular structure, which is clamped between the outer shell 71 and the base 5. It can not only position the base 5 located in the shell 7, but also the connecting portion 721 has an interference fit with the outer shell and the base 5. After being pressed together, it can provide strong support, greatly improve the tensile strength, and ensure the stability of the structure.
