However, as is well known, it is difficult to achieve a seal between hardware components. When oil reaches the heating wire from the lower oil hole, the heating wire is in direct contact with the plane containing the lower oil hole, and oil can easily flow from the gap between the heating wire and the plane containing the lower oil hole into the atomizing chamber, resulting in oil leakage.

[0024] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. The various technical features of this utility model can be combined interactively without contradicting each other.

[0025] Reference Figures 1 to 8 Firstly, this utility model proposes an atomizer, including an oil cup 100, a support 200, a heating element 300, and an oil guide 400, which can effectively solve the oil leakage problem while reducing the number of atomizer parts.

[0026] Specifically, refer to Figure 2 , Figure 3 and Figure 4The oil cup 100 has a liquid storage chamber 110. The support 200 includes a base 230 and a main body 210 located on the base 230. The main body 210 is disposed inside the oil cup 100, and the base 230 is located outside the oil cup 100. One side of the main body 210 has a mounting surface 211 and a liquid guiding portion 220 protruding from the mounting surface 211. The mounting surface 211 has an atomizing groove 212. An oil guide body 400 is disposed on one side of the mounting surface 211. A heating element 300 is located between the oil guide body 400 and the mounting surface 211, corresponding to the position of the atomizing groove 212. The oil guide body 400 and the heating element 300, together with the atomizing groove 212, form an atomizing channel 510. The support 200 also has an air intake channel 240, at least partially formed on the base 230, communicating with the external atmosphere and the atomizing groove 212.

[0027] It is worth noting that the liquid guiding part 220 has a contact surface 221 on one side. The contact surface 221 and the mounting surface 211 are located on the same side of the support 200. Moreover, the contact surface 221 is provided with a liquid guiding port 222, which is connected to the liquid storage cavity 110. The oil guiding body 400 covers the liquid guiding port 222 and abuts against the contact surface 221.

[0028] Understandably, since the liquid guiding part 220 protrudes from the mounting surface 211, the oil guiding body 400 can directly and tightly fit with the contact surface 221, thereby avoiding oil leakage caused by the gap between the heating element 300 and the oil guiding body 400.

[0029] In some specific embodiments, the oil guide 400 is a flat cotton core. After absorbing oil, the oil guide 400 expands, pressing against the contact surface 221 to form a seal at the liquid outlet 222, preventing oil leakage. It is understood that the oil guide 400 can completely cover the contact surface 221 or only partially cover it; no specific limitation is made here, as long as the liquid outlet 222 is completely covered.

[0030] In some embodiments, the contact surface 221 protrudes from the surface of the heating element 300 facing the oil guide body 400 in the direction along the vertical mounting surface 211. In other embodiments, the contact surface 221 is flush with the surface of the heating element 300 facing the oil guide body 400. This arrangement further ensures that the contact surface 221 can contact the oil guide body 400, thereby preventing oil leakage.

[0031] In some embodiments, the height difference between the contact surface 221 and the mounting surface 211 or the surface of the heating element 300 facing the oil guide body 400 is greater than or equal to 0.1 mm and less than or equal to 1.2 mm. For example, it can be 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, or 1.2 mm, but is not limited thereto. When the heating element 300 is mounted on the mounting surface 211, it ensures that the contact surface 221 directly contacts the oil guide body 400, forming a sealing structure to prevent oil leakage. Furthermore, it ensures the stability of the heating element 300 mounted on the mounting surface 211, preventing the heating element 300 from wobbling in the direction perpendicular to the mounting surface 211, thereby effectively achieving liquid atomization.

[0032] In some embodiments, the contact surface 221 is a plane, and the oil guide body 400 and the contact surface 221 make contact through the plane, which can further ensure a tight contact. In some embodiments, the contact surface 221 and the mounting surface 211 are arranged parallel to each other, which can also ensure good contact between the contact surface 221 and the oil guide body 400. In some embodiments, the contact surface 221 is a plane, and the contact surface 221 and the mounting surface 211 are parallel to each other. The surface of the oil guide body 400 facing the mounting surface 211 is set as a plane parallel to the mounting surface 211 to achieve tight contact with the contact surface 221, and the processing and production of the oil guide body 400 and the support 200 are simpler.

[0033] In some embodiments, refer to Figure 5 and Figure 6 The heating element 300 includes a first conductive part 310, a heating part 320, and a second conductive part 330. The first conductive part 310, the heating part 320, and the second conductive part 330 are arranged sequentially along a second direction, that is, the first conductive part 310 and the second conductive part 330 are respectively connected to the two sides of the heating part 320. The second direction is parallel to the mounting surface 211.

[0034] The first conductive part 310 and the second conductive part 330 are respectively connected to the mounting surface 211 and are used to connect to the external power supply; the heating part 320 and the atomizing groove 212 enclose to form an atomizing channel 510 and are used to heat and atomize the liquid.

[0035] In some embodiments, the first conductive part 310, the heating part 320, and the second conductive part 330 are integrally formed.

[0036] It should be noted that in some embodiments, the heating element 300 is a heating wire, and the heating element 300 can be separately disposed from the oil guide body 400. Of course, the heating element 300 and the oil guide body 400 can also be an integral structure, and the heating element 300 can also be a heating film or other heating structure, which is not limited here.

[0037] In some embodiments, refer to Figures 6 to 8 One or both of the first conductive part 310 and the second conductive part 330 are provided with a clearance hole 350, and the liquid guiding part 220 passes through the clearance hole 350 so that the contact surface 221 contacts the oil guiding body 400.

[0038] By setting a clearance hole 350 that cooperates with the contact surface 221, the contact surface 221 and the oil guide body 400 can achieve good contact, thereby avoiding oil leakage. At the same time, the clearance hole 350 can position and fix the heating element 300, reducing the problem of deformation caused by displacement during assembly and the inability to fit tightly with the oil guide body 400.

[0039] It is understood that there can be one or more liquid guiding parts 220. Multiple liquid guiding parts 220 can be arranged on the same side of the atomizing tank 212 or on both sides of the atomizing tank 212.

[0040] In some embodiments, a liquid guiding section 220 is provided on each side of the atomizing tank 212. Each of the contact surfaces 221 of the two liquid guiding sections 220 is provided with a liquid guiding port 222 communicating with the oil storage chamber. Correspondingly, the first conductive section 310 and the second conductive section 330 are each provided with a clearance hole 350. The two liquid guiding sections 220 pass through the clearance holes 350 of the first conductive section 310 and the second conductive section 330, respectively. This arrangement allows the oil absorption of the oil guide body 400 on both sides of the atomizing tank 212 to be approximately balanced. The liquid is more evenly absorbed into the heating area for heating and atomization after passing through the oil guide body 400, thus improving the liquid atomization effect.

[0041] In some embodiments, refer to Figure 5 One or both of the first conductive part 310 and the second conductive part 330 are provided with a relief groove 340. The relief groove 340 is provided with an opening facing the liquid guiding part 220, that is, the groove wall of the relief groove 340 is provided along the edge of the liquid guiding part 220. In this way, the heating element 300 can also avoid contact with the liquid guiding part 220, so that the contact surface 221 can directly contact the oil guiding body 400, thereby achieving the effect of preventing oil leakage.

[0042] In some embodiments, the first conductive part 310 and the second conductive part 330 are both provided with relief grooves 340, and the liquid guiding part 220 is symmetrically arranged on both sides of the atomizing groove 212, which can make the oil absorption of the oil guiding body 400 on both sides of the atomizing groove 212 roughly balanced. The oil is more evenly absorbed into the heating area for heating and atomization through the oil guiding body 400, which can improve the liquid atomization effect.

[0043] In some embodiments, refer to Figure 3 The main body 210 is also provided with an oil discharge channel 224, which extends to the end away from the base 230. The oil discharge channel 224 connects the liquid guide port 222 and the liquid storage chamber 110. Specifically, the oil discharge channel 224 is provided with an opening facing the liquid storage chamber 110, and the liquid guide port 222 passes through the contact surface 221 and communicates with the oil discharge channel 224, thereby realizing the communication between the liquid guide port 222 and the liquid storage chamber 110.

[0044] In some embodiments, the contact surface 221 is provided with a return air port 223 and a return air groove 225. The return air groove 225 is connected to the liquid storage chamber 110 through the return air port 223. The end of the return air groove 225 away from the return air port 223 is connected to the atmosphere. The oil guide body 400 and the return air groove 225 enclose at least a portion of the return air passage. In embodiments where an oil discharge passage 224 is provided, the return air port 223 is connected to the liquid storage chamber 110 through the oil discharge passage 224.

[0045] Understandably, when a user uses the atomizer, the atomizing medium, such as oil, is atomized by the heating element 300, and the user draws it in through the atomization channel 510. The atomizing medium in the storage chamber 110 is continuously consumed. In order to ensure that the atomizing medium can flow continuously and smoothly from the storage chamber 110 to the liquid inlet 222 and be absorbed by the oil guide body 400, a return air inlet 223 and a return air groove 225 are provided to connect the storage chamber 110 with the outside atmosphere, realize the return air to the storage chamber 110, and ensure the air pressure balance inside and outside the storage chamber 110.

[0046] Understandably, since the return air port 223 and the return air groove 225 are located on the contact surface 221, and the oil guide body 400 abuts against the contact surface 221, when the atomizing medium flows out through the return air port 223 and the return air groove 225, the atomizing medium can be absorbed by the oil guide body 400 in a timely manner, avoiding leakage of the atomizing medium and ensuring the reliability of the atomizer.

[0047] In some embodiments, refer to 3 and Figure 4 The atomizer also includes an air passage component 500, which is disposed within the atomization groove 212. The air passage component 500 and the heating element 300 enclose each other to form an atomization channel 510. Specifically, the air passage component 500 is provided with an air passage, the shape of which is set according to actual needs, and the air passage is set to open towards the heating element 300.

[0048] In some embodiments, the airway component 500 is made of materials such as silicone or rubber.

[0049] It is understandable that the oil guide body 400 can completely cover the return air port 223 or cover a part of the return air port 223; no specific limitation is made here.

[0050] In some embodiments, the perforated area of ​​the return air port 223 on the contact surface 221 is smaller than the perforated area of ​​the liquid guide port 222 on the contact surface 221.

[0051] In some embodiments, the support 200 has two oil channels 224 in the liquid guiding part 220, two liquid guiding parts 220, and a return air port 223 is provided on the contact surface 221 of both liquid guiding parts 220.

[0052] In some embodiments, the atomizer further includes a pressing member 600, which is connected to the support 200 and abuts against the side of the wicking body 400 away from the heating element 300. The pressing member 600 can provide pressure to the wicking body 400 toward the heating element 300, thereby making the connection between the wicking body 400 and the contact surface 221 tighter, thus further improving the reliability of the sealing structure formed by the wicking body 400 and the contact surface 221, and further preventing oil leakage.

[0053] In some embodiments, the pressing member 600 is detachably connected to the outside of the support 200. Specifically, the pressing member 600 has a snap-fit ​​on both sides, and the support 200 has a connecting protrusion on both sides. The position of the snap-fit ​​corresponds to the position of the protrusion. After the air passage 500, the heating element 300 and the oil guide 400 are installed on the support 200, the pressing member 600 is installed so that the protrusion is snapped into the corresponding snap-fit, thereby achieving a stable connection between the components.

[0054] It should be noted that in some specific embodiments, the pressing component 600 is a steel sheet. Of course, the pressing component 600 can also be made of other materials, and no specific limitation is made here.

[0055] In some embodiments, the air intake channel 240 includes an air intake passage 241 disposed on the base 230 and an air intake groove 242 disposed on the main body 210 and extending circumferentially. The air intake groove 242 connects the atomizing chamber 212 and the air intake passage 241, and extends circumferentially along the main body 210. The air intake passage 241 and the air intake groove 242 are provided to reduce the outflow of condensate from the atomizer through the air intake channel 240.

[0056] In a second aspect, the present invention provides an atomizing device, which includes a power supply component and an atomizer as described in any one of the embodiments of the first aspect, wherein the power supply component is electrically connected to the heating element 300 in the atomizer, and the power supply component is used to supply power to the heating element 300.

[0057] Since the atomizing device uses the aforementioned atomizer, it also possesses all the beneficial effects of the aforementioned atomizer, which will not be elaborated upon here.

[0058] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
