[0037] Please refer to Figures 1-8 This utility model proposes an atomizing heating device, including an atomizing body 1, a nozzle 2, and an oil replenishment assembly 3. The atomizing body 1 has an oil storage chamber 17 and an atomizing channel 16 passing through the oil storage chamber 17. One end of the atomizing body 1 extends outward with an air guide pipe 14 communicating with the atomizing channel 16 and an oil guide pipe 15 communicating with the oil storage chamber 17. The nozzle 2 has a detachable cover attached to the atomizing body 1, and the nozzle 2 has an air outlet connected to the air guide pipe 14. The oil replenishment assembly 3 has a sealed oil replenishment chamber 34 and an air outlet pipe 33 passing through the oil replenishment chamber 34. The side wall of the oil replenishment chamber 34 has an oil replenishment hole 37 corresponding to the oil guide pipe 15, and the oil replenishment hole 37 is detachably filled with a sealing element 36. When the mouthpiece 2 is detached from the atomizing body 1, the oil replenishment assembly 3 is installed on the atomizing body 1, and the air guide tube 14 is inserted into the air outlet tube 33. The oil guide tube 15 is inserted into the oil replenishment hole 37 and pushes the sealing member 36 into the oil replenishment chamber 34, so that the oil storage chamber 17 is connected to the oil replenishment chamber 34 via the oil guide tube 15. With the replaceable mouthpiece 2 detachable from the oil replenishment chamber 34, after the oil stored in the oil storage chamber 17 of the atomizing body 1 is depleted, it can be replenished from the oil replenishment chamber 34 via the oil guide tube 15, facilitating user operation and oil replenishment.

[0038] In some embodiments, such as Figure 2-4As shown, the atomizing body 1 includes a shell 11 and a sealing seat 12. The shell 11 has a hollow structure and an opening 111 at one end. The sealing seat 12 is installed at the opening 111 and forms a sealed oil storage chamber 17 with the shell 11. The oil storage chamber 17 can directly store oil or be filled with an oil storage component to draw in oil. An air guide tube 14 and an oil guide tube 15 protrude from the end of the shell 11 opposite to the sealing seat 12. There can be one, two, or more oil guide tubes 15. Correspondingly, the oil replenishment component 3 has a corresponding number of oil replenishment holes 37 for the oil guide tubes 15 to be inserted into. An atomizing core component 13 is installed in the oil storage chamber 17. The atomizing core component 13 is used to heat the oil to generate an aerosol. One end of the atomizing core component 13 is inserted into the sealing seat 12, and the other end is connected to the air guide tube 14, thereby forming an atomizing channel 16 that runs through the oil storage chamber 17. Correspondingly, the sealing seat 12 is provided with an air inlet 121 that communicates with the atomizing channel 16. In practical applications, the air inlet 121 can be coaxially arranged with the air guide tube 14, or it can be arranged in other parts of the sealing seat 12; no limitation is made here. Outside air can enter the atomizing channel 16 through the air inlet 121, and the aerosol generated after atomization flows out of the atomizing body 1 through the air guide tube 14.

[0039] In some embodiments, such as Figure 3 As shown, the nozzle 2 has a clearance hole 22 corresponding to the oil guide tube 15. When the nozzle 2 covers the housing 11, the oil guide tube 15 is inserted into the corresponding clearance hole 22, and the air guide tube 14 is connected to the air outlet 21, so that the aerosol flows out from the air outlet 21 through the air guide tube 14. In this embodiment, the nozzle is detachably installed on the atomizing body by inserting the oil guide tube into the clearance hole and the air guide tube 14 into the air outlet 21. In practical applications, a mounting groove adapted to the outer periphery of the housing 11 can also be provided on the nozzle 2, and a detachable connection can be achieved by the interference fit between the mounting groove and the outer periphery of the housing 11. Alternatively, a snap-fit ​​can be provided on the housing 11 and a snap-fit ​​groove can be provided on the nozzle 2, and the nozzle 2 can be detachably installed on the atomizing body 1 by a snap-fit ​​connection.

[0040] In some embodiments, please refer to Figures 5-7The oil replenishment assembly 3 includes a cover 31, a base 32, and an air outlet 33. The cover 31 has a receiving groove (not shown in the figure), and the base 32 closes the opening end of the receiving groove to form the oil replenishment chamber 34 with the cover 31. In practical applications, the cover 31 may include a soft rubber part 321 and a hard rubber part 322. The size and shape of the hard rubber part 322 are adapted to the opening end, and the soft rubber part 321 at least partially covers the hard rubber part 322 to form the base 32. Thus, when the base 32 is installed at the opening end, the soft rubber part 321 elastically abuts against the hard rubber part 322 and the side wall of the receiving groove to seal the installation gap between the cover 31 and the base 32. The soft rubber part 321 and the hard rubber part 322 may be integrally formed or detachably connected. One end of the air outlet pipe 33 is inserted through the base 32, and the other end penetrates the top wall of the receiving groove and partially protrudes from the top wall beyond the cover 31 for user suction. In practical applications, the protruding part of the air outlet pipe 33 can be designed as a suction nozzle for user suction. The air outlet pipe 33 can be integrally connected to the cover 31 or can be a separate component.

[0041] In some embodiments, please refer to Figure 7 The oil replenishment hole 37 is located on the base 32, and correspondingly, the oil guide pipe 15 is located on the side of the housing 11 away from the sealing seat 12. The sidewall of the receiving groove extends away from the base 32 and forms a receiving groove 35 that is adapted to the outer periphery of the atomizing body by the outer periphery of the housing 11 and the base 32. The receiving groove 35 is detachably covered on the outer periphery of the housing 11. In practical applications, a slot can be provided on the inner sidewall of the receiving groove 35, and a matching snap can be provided on the outer periphery of the housing 11 to install the oil replenishment chamber 34 on the atomizing body 1. Of course, a detachable connection can also be achieved by means of threaded connection, interference fit, etc. When the oil replenishment chamber 34 is installed on the atomizing body 1, the air guide pipe 14 passes through the base 32 and connects to the air outlet pipe 33 to connect the atomizing channel 16 and the air outlet pipe 33. Simultaneously, the oil guide pipe 15 is inserted into the oil replenishment hole 37, and the sealing element 36 inside the oil replenishment hole 37 is pushed into the oil replenishment chamber 34 to connect the oil replenishment chamber 34 and the oil storage cavity 17. In this embodiment, by filling the oil replenishment hole 37 with the sealing element 36 to seal the oil replenishment hole 37, when oil replenishment is needed, the thrust of the oil guide pipe 15 inserted into the oil replenishment hole 37 pushes the sealing element 36 into the oil replenishment chamber 34, thereby achieving rapid connection of the oil replenishment circuit. No additional operation is required to remove the sealing element 36, ensuring reliable sealing and convenient operation.

[0042] It is worth noting that the oil replenishment hole 37 can also be set in other parts of the oil replenishment assembly, such as on the side wall of the receiving groove. Correspondingly, the oil guide pipe 15 is set on the side wall of the housing 11.

[0043] In some embodiments, such as Figure 8 As shown, the sealing element 36 includes a sealing element body 361, the outer periphery of which is adapted to the diameter of the oil replenishment hole 37. The sealing element body 361 is housed within the oil replenishment hole 37, and the outer periphery of the sealing element body 361 elastically abuts against the inner wall of the oil replenishment hole 37. By sealing the oil replenishment hole 37 with the sealing element body 361, the oil in the oil replenishment tank 34 will not leak from the oil replenishment hole 37.

[0044] In some embodiments, limiting rings 362 protrude from both ends of the sealing body 361. The outer diameter of the limiting rings 362 is slightly larger than the diameter of the oil filling hole 37. When the sealing member 36 fills the oil filling hole 37, the limiting rings 362 are located outside the oil filling hole 37, and the end faces of both ends of the oil filling hole 37 abut against the corresponding limiting rings 362. The limiting rings 362 restrict the axial displacement of the sealing body 361, preventing the sealing member 36 from falling out of the oil filling hole 37 and causing sealing failure. Furthermore, the ends of the two limiting rings 362 that are opposite to each other are provided with chamfers. This makes the outer diameter of the chamfered portion of the limiting ring 362 the smallest. During installation, the chamfered portion is first inserted into the oil filling hole 37, which serves as a guide and helps reduce the installation difficulty of the sealing body 361.

[0045] In some embodiments, the sealing body 361 is provided with at least one blind hole 363 coaxial with the oil replenishment hole 37. That is, the blind hole 363 does not penetrate the sealing body 361, which ensures sealing performance and also makes the sealing member 36 more prone to elastic deformation. When the oil guide tube 15 is inserted into the oil replenishment hole 37, the sealing member 36 is more likely to deform under the thrust and be pushed into the oil replenishment chamber 34, thereby reducing the difficulty for the user to install the oil replenishment chamber 34.

[0046] In some embodiments, the oil replenishment hole 37 is provided with tapered guide portions (not shown in the figure) at both ends. The diameters of the two tapered guide portions gradually increase in opposite directions. That is, the diameter of the tapered guide portion facing outward from the oil replenishment hole 37 is the largest, which facilitates the installation of the sealing body 361 and also guides the oil guide tube 15 into the oil replenishment hole 37.

[0047] In some embodiments, such as Figure 6As shown, one end of the oil guide pipe 15 inserted into the oil replenishment hole 37 protrudes into the oil replenishment chamber 34. That is, the opening of the oil guide pipe 15 is higher than the bottom surface of the oil replenishment chamber 34, so that the opening is less likely to be blocked by the sealing element 36 housed in the oil replenishment chamber 34, reducing the probability of the oil passage being blocked. Furthermore, the end of the oil guide pipe 15 protruding into the oil replenishment chamber 34 is provided with at least one first slot 151. The first slot 151 extends along the axial direction of the oil guide pipe 15 and connects the oil guide pipe 15 and the oil replenishment chamber 34. In this way, even if the opening of the oil guide pipe 15 is blocked, the oil in the oil replenishment chamber 34 can still flow into the oil guide pipe 15 through the first slot 151, thereby ensuring the smooth flow of the oil replenishment passage.

[0048] For further details, please refer to... Figure 2 and Figure 8 The other end of the oil guide pipe 15 protrudes into the oil replenishment chamber, and the protruding portion is provided with at least one second slot 152. The second slot 152 extends radially along the oil guide pipe 15 and connects the oil guide pipe 15 with the oil storage chamber 17. When the oil in the oil replenishment tank 34 flows into the oil storage chamber 17 through the oil guide pipe 15, the air in the oil storage chamber 17 can be discharged through the second slot 152. The second slot 152 accelerates the discharge of air from the oil storage chamber 17, which is beneficial to improving the oil replenishment efficiency.

[0049] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
