Description

Technical Field

[0001] This utility model relates to the field of atomization technology, and in particular to an aerosol generating device. Background Technology

[0002] Aerosol generators, also known as virtual cigarettes, electronic cigarettes, vaporizers, etc., are mainly used to simulate the feeling of smoking without affecting health, for the purpose of quitting smoking or replacing cigarettes. Existing aerosol generators can be roughly divided into three categories: 1. With a reservoir: Compared with open-oil products, the atomization and inhalation experience of the reservoir type is slightly inferior, and with the same amount of e-liquid, the space utilization is low and the volume is large; 2. Open-type (self-filling): During use, adding e-liquid will cause leakage from the center hole of the atomizer coil (after opening the filling plug, the pressure difference balance inside and outside the cartridge is broken), affecting the experience; 3. Pre-filled (commonly 2ml capacity on the market): Large-capacity products cannot pass reliability tests and are prone to leakage, affecting the experience.

[0003] Existing large-capacity aerosol generators all have drawbacks. The oil-absorbing cotton has a slightly inferior feel and low space utilization. Open-type devices without oil filling leak oil, while pre-filled devices are prone to oil leakage.

[0004] Under the above circumstances, there is an urgent need for a product that can solve the problem of oil leakage during the transportation and use of the ventilation mist generator. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an aerosol generating device, which can provide a pressure-reducing channel and a pressure-reducing chamber above the oil guide component. When the aerosol generating device is in a negative pressure environment, the e-liquid in the oil guide component flows upward along the pressure-reducing channel and the pressure-reducing chamber to relieve pressure. When the aerosol generating device is in a positive pressure environment, the e-liquid in the pressure-reducing channel and the pressure-reducing chamber flows downward back to the oil guide component.

[0006] This utility model provides an aerosol generator, including a housing, a mounting base, and an atomizing component;

[0007] The housing is provided with an oil storage chamber and an exhaust hollow pipe. The oil storage chamber is used to hold e-liquid, and the exhaust hollow pipe is provided with an airflow channel communicating with the outside. The mounting base is installed at one end of the housing.

[0008] The atomizing assembly includes an atomizing hollow tube and an atomizing core mounted on the atomizing hollow tube. The atomizing core includes an oil guide and a heating element. The lower end of the atomizing hollow tube is fixed on the mounting base, and the upper end of the atomizing hollow tube is inserted into the exhaust hollow tube.

[0009] The outer surface of the upper end of the atomizing hollow tube is recessed to form a pressure-reducing channel and a pressure-reducing cavity. The pressure-reducing channel and the pressure-reducing cavity are located above the oil guide. The two ends of the pressure-reducing channel are respectively connected to the oil guide and the pressure-reducing cavity. The e-liquid in the oil guide can flow into the pressure-reducing cavity through the pressure-reducing channel.

[0010] Furthermore, the housing is also provided with an oil inlet channel, the two ends of which are respectively connected to the oil storage chamber and the oil guide. The oil inlet channel has at least one bend, and the e-liquid in the oil storage chamber flows into the oil guide after being buffered by the bend of the oil inlet channel.

[0011] Furthermore, the oil storage cavity is positioned higher than the oil guide, and the two ends of the oil inlet channel are respectively connected to the bottom of the oil storage cavity and the side of the oil guide.

[0012] Furthermore, the oil guide is embedded in the atomizing hollow tube, and the heating element is in contact with the oil guide. The heating element is used to atomize the e-liquid in the oil guide and enter the atomizing hollow tube.

[0013] Furthermore, the lower end of the atomizing hollow tube is provided with an atomizing base integrally formed with the atomizing hollow tube. The oil guiding component has a U-shaped structure and includes two parallel oil guiding main bodies. The two oil guiding main bodies are respectively installed on both sides of the atomizing base, and the heating element is simultaneously attached to the inner wall surface of the two oil guiding main bodies.

[0014] Furthermore, the pressure relief channel includes an annular groove section and a first curved groove section. The annular groove section is arranged around the atomizing hollow tube. The two ends of the first curved groove section are respectively connected to the annular groove section and the pressure relief chamber. The first curved groove section has at least one bend. The e-liquid in the oil guide first flows into the annular groove section, and then flows from the annular groove section into the pressure relief chamber through the first curved groove section.

[0015] Furthermore, the outer surface of the upper end of the atomizing hollow tube is recessed to form a venting channel, and the two ends of the venting channel are respectively connected to the pressure reducing chamber and the airflow channel.

[0016] Furthermore, the inner wall of the exhaust hollow pipe is provided with an outwardly flared inclined surface, which is located above the venting channel. The inclined surface is used to guide the condensate formed in the exhaust hollow pipe into the venting channel and flow into the pressure reducing chamber through the venting channel.

[0017] Furthermore, the venting channel includes a second curved groove section and a straight groove section. The second curved groove section is disposed above the pressure reducing chamber. The straight groove section extends along the axial direction of the atomizing hollow tube, and both ends of the straight groove section are respectively connected to the second curved groove section and the pressure reducing chamber. Both ends of the second curved groove section are respectively connected to the straight groove section and the airflow channel. The second curved groove section has at least one bend.

[0018] Furthermore, the pressure-reducing chamber is provided around the outer surface of the atomizing hollow tube.

[0019] In summary, this embodiment of the invention allows for the depressurization channel and depressurization chamber to be provided above the oil guide component. When the aerosol generator is in a negative pressure environment, the e-liquid in the oil guide component flows upward along the depressurization channel and depressurization chamber to relieve pressure. When the aerosol generator is in a positive pressure environment, the e-liquid in the depressurization channel and depressurization chamber flows downward back to the oil guide component.

[0047] The following detailed explanation uses specific examples:

[0048] like Figures 1 to 13 As shown, this utility model embodiment provides an aerosol generator, including a housing 100, a mounting base 200, and an atomizing component 300;

[0049] The housing 100 is provided with an oil storage chamber 110 and an exhaust hollow pipe 120. The oil storage chamber 110 is used to hold e-liquid, and the exhaust hollow pipe 120 is provided with an airflow channel 121 that communicates with the outside. The mounting base 200 is installed at one end of the housing 100.

[0050] The atomizing assembly 300 includes an atomizing hollow tube 310 and an atomizing core 320 mounted on the atomizing hollow tube 310. The atomizing core 320 includes an oil guide 321 and a heating element 322. The lower end of the atomizing hollow tube 310 is fixed on the mounting base 200, and the upper end of the atomizing hollow tube 310 is inserted into the exhaust hollow tube 120.

[0051] The outer surface of the upper end of the atomizing hollow tube 310 is recessed to form a pressure relief channel 311 and a pressure relief chamber 312. The pressure relief channel 311 and the pressure relief chamber 312 are located above the oil guide 321. The two ends of the pressure relief channel 311 are connected to the oil guide 321 and the pressure relief chamber 312 respectively. The e-liquid in the oil guide 321 can flow into the pressure relief chamber 312 through the pressure relief channel 311.

[0052] Specifically, the oil guide 321 is an oil guide cotton that can store e-liquid and provide it to the heating element 322 for atomization. E-liquid can also flow into or out of the oil guide 321.

[0053] like Figures 1 to 4 As shown, in this embodiment, the aerosol generator further includes an oil-absorbing component 400, an electronic component 500, and a base 600. The base 600 is fixedly connected to the housing 100 to form a complete outer shell. The mounting base 200, atomizing component 300, oil-absorbing component 400, and electronic component 500 are installed together within the outer shell formed by the base 600 and the housing 100. The oil-absorbing component 400 is located below the atomizing component 300 and is used to absorb condensate or e-liquid flowing down from the atomizing component 300. The electronic component 500 is located next to the oil-absorbing component 400 and includes electronic components such as a battery circuit board, used to power the heating element 322 and control the switching of the aerosol generator. The base 600 has an air inlet at the bottom, which is connected to the bottom of the atomizing component 300 to provide air intake for the atomizing component 300. Air from outside the atomizing device enters through the air inlet, mixes with the atomized e-liquid when passing through the atomizing component 300, and then passes through the atomizing hollow tube 310 and the exhaust hollow tube 120 before being inhaled by the user.

[0054] like Figure 5 , Figure 8 , Figure 11 As shown, in this embodiment, the housing 100 is also provided with an oil inlet channel 130. The two ends of the oil inlet channel 130 are respectively connected to the oil storage chamber 110 and the oil guide 321. The oil inlet channel 130 is provided with at least one bend. The e-liquid in the oil storage chamber 110 flows into the oil guide 321 after being buffered by the bend of the oil inlet channel 130.

[0055] Specifically, the oil inlet channel 130 has two bends to reduce the impact force of the e-liquid flow. The first section of the oil inlet channel 130 is vertically downward, after a first 90° bend, the second section is horizontal, after a second 90° bend, and the third section flows horizontally and perpendicular to the second section into the oil guide component 321. There are two oil inlet channels 130, which are respectively connected to the two oil guide body parts 3211 on the side of the oil guide component 321.

[0056] Specifically, the impact of liquid gravity on the wicking element 321 can be adjusted by regulating the shape and size of the inlet of the inlet channel 130, and is not limited to the circular shape shown in this embodiment. E-liquid permeates into the wicking element 321 through the inlet channel 130. The bends in the inlet channel 130 can buffer the oil pressure and reduce the inlet speed. Especially during vibration, the inlet channel 130 acts like a bay, providing a buffer and preventing oil from being continuously forced into the atomizer coil 320, thus avoiding leakage.

[0057] In this embodiment, the oil storage cavity 110 is positioned higher than the oil guide 321, and the two ends of the oil inlet channel 130 are respectively connected to the bottom of the oil storage cavity 110 and the side of the oil guide 321.

[0058] Specifically, the e-liquid in the oil storage chamber 110 flows into the oil guide component 321 through the oil inlet channel 130 under the action of gravity. The oil storage chamber 110 is designed with a large capacity, and an oil filling hole 140 is also provided at the bottom of the oil storage chamber 110. The oil filling hole 140 is used to inject e-liquid into the oil storage chamber 110. After the injection is completed, the oil filling hole 140 is plugged with a plug. Both the oil filling hole 140 and the oil inlet channel 130 are opened in the mounting base 200. When the mounting base 200 is fixedly connected to the housing 100, the top of the mounting base 200 and the inner cavity of the housing 100 form the oil storage chamber 110.

[0059] Specifically, the mounting base 200, in conjunction with the housing 100, divides the aerosol generator into two independent chambers. The top of the mounting base 200 and the housing 100 form an oil storage chamber 110 as the first chamber, while the mounting base 200 and the atomizing component 300 form a second chamber to accommodate the oil guide 321. Assuming the combined volume of the two chambers is 10ml, the second chamber (oil guide 321) has a capacity of 2ml, and the first chamber (oil storage chamber 110) has a capacity of 8ml. This means that the atomizing coil 320 only needs to withstand a pressure difference of approximately 1 / 5 of its original volume, reducing the risk of leakage.

[0060] like Figures 5 to 7 As shown, in this embodiment, the oil guide 321 is embedded in the atomizing hollow tube 310, and the heating element 322 is attached to the oil guide 321. The heating element 322 is used to atomize the e-liquid in the oil guide 321 and enter the atomizing hollow tube 310.

[0061] In this embodiment, the lower end of the atomizing hollow tube 310 is also provided with an atomizing base 313 integrally formed with the atomizing hollow tube 310. The oil guide 321 has a U-shaped structure and includes two parallel oil guide main bodies 3211. The two oil guide main bodies 3211 are respectively installed on both sides of the atomizing base 313, and the heating element 322 is simultaneously attached to the inner wall surface of the two oil guide main bodies 3211.

[0062] Specifically, the heating element 322 is a planar mesh shape (the traditional atomizing core 320 is a circular heating wire (mesh) wrapped around the heating element), and is fixed to the atomizing base 313 by rib (rib) interference and (riveting) pressing. There are two heating elements 322, respectively located on both sides of the atomizing base 313. This embodiment does not limit the number of heating elements 322; single-mesh, three-mesh, or even multi-mesh layouts should be considered as having the same structure as this embodiment.

[0063] Specifically, the oil guide 321 is U-shaped with an opening in the middle. The oil guide 321 is mounted on the atomizing base 313 in a hanging manner, and the atomizing hollow tube 310 passes through the opening in the middle of the oil guide 321. The oil guide bodies 3211 on both sides cover the two heating elements 322. When the two heating elements 322 are working, the atomized mist flows into the atomizing hollow tube 310 from two directions, resulting in higher atomization efficiency and better atomization uniformity.

[0064] like Figures 12 to 13 As shown, in this embodiment, the pressure relief channel 311 includes an annular groove section 3111 and a first curved groove section 3112. The annular groove section 3111 is arranged around the atomizing hollow tube 310. The two ends of the first curved groove section 3112 are respectively connected to the annular groove section 3111 and the pressure relief chamber 312. The first curved groove section 3112 is provided with at least one bend. The e-liquid in the oil guide 321 first flows into the annular groove section 3111, and then flows from the annular groove section 3111 through the first curved groove section 3112 into the pressure relief chamber 312.

[0065] Specifically, since the oil guide 321 is U-shaped and attached to the atomizing base 313, the annular groove 3111 can effectively collect and gather e-liquid before it flows into the first curved groove 3112. The pressure relief channel 311 serves to release pressure and can also act as an oil passage. When the oil pressure in the oil guide 321 is high, the e-liquid enters the pressure relief chamber 312 through the pressure relief channel 311.

[0066] In this embodiment, the outer surface of the upper end of the atomizing hollow tube 310 is also recessed to form a venting channel 314, and the two ends of the venting channel 314 are respectively connected to the pressure reducing chamber 312 and the airflow channel 121.

[0067] In this embodiment, the venting channel 314 includes a second curved groove section 3141 and a straight groove section 3142. The second curved groove section 3141 is disposed above the pressure reducing chamber 312. The straight groove section 3142 extends along the axial direction of the atomizing hollow tube 310, and both ends of the straight groove section 3142 are connected to the second curved groove section 3141 and the pressure reducing chamber 312, respectively. Both ends of the second curved groove section 3141 are connected to the straight groove section 3142 and the airflow channel 121, respectively. The second curved groove section 3141 has at least one bend.

[0068] Specifically, the function of the straight groove section 3142 is to facilitate the flow of e-liquid into the decompression chamber 312, and the e-liquid will first fill the decompression chamber 312 before flowing out from the straight groove section 3142, rather than flowing out directly from the straight groove section 3142 before the decompression chamber 312 is full.

[0069] Specifically, the working principle of the pressure reducing chamber 312 is similar to that of an automatic water dispenser. The upper part of the oil guide 321 is connected to the atomizing hollow tube 310 through the pressure reducing channel 311, the pressure reducing chamber 312 and the venting channel 314, and then connected to the outside atmosphere. Every time the user takes a breath of mist, the oil guide 321 will take in a little oil through the oil inlet channel 130 to ensure that the product has sufficient oil supply and does not burn the core.

[0070] Specifically, when the ambient air pressure of the aerosol generator decreases, such as during transport or carrying on an airplane, the ambient air pressure is lower than the air pressure inside the aerosol generator. A pressure difference exists between the oil guide 321 and the ambient air pressure, causing e-liquid to flow out of the oil guide 321. Without the pressure relief channel 311 and pressure relief chamber 312, e-liquid would seep out of the aerosol generator along the exhaust hollow pipe 120. However, the pressure relief channel 311 and pressure relief chamber 312 in this embodiment guide the e-liquid in until the internal and external air pressure difference is balanced. When the ambient air pressure increases, such as when an airplane lands, the ambient air pressure is higher than the air pressure inside the aerosol generator. A pressure difference exists between the oil guide 321 and the ambient air pressure, causing e-liquid to flow back into the oil guide 321 along the pressure relief chamber 312 and the oil inlet channel 130 until the internal and external air pressure difference is balanced.

[0071] In this embodiment, the pressure relief chamber 312 is arranged around the outer surface of the atomizing hollow tube 310. The upper end of the outer surface of the atomizing hollow tube 310 is recessed and forms a pressure relief chamber 312 with the inner wall of the exhaust hollow tube 120, which is equivalent to a small oil tank for temporarily storing e-liquid.

[0072] like Figure 5 As shown, in this embodiment, the inner wall of the exhaust hollow pipe 120 is provided with an outwardly expanding inclined surface 122. The inclined surface 122 is located above the venting channel 314. The inclined surface 122 is used to guide the condensate formed in the exhaust hollow pipe 120 into the venting channel 314 and flow into the pressure reducing chamber 312 through the venting channel 314.

[0073] Specifically, the condensate formed in the exhaust hollow pipe 120 enters the pressure relief chamber 312 through the second curved groove section 3141, and finally flows back to the oil guide component 321 through the pressure relief channel 311 for reuse.

[0074] The scope of protection of this utility model is not limited to the single part mentioned above. Any combination of two or three parts to form a new superior single part, or any new part added to the structure of this embodiment (or an increase in the number of a certain part) that has the same air release and pressure relief function, and whose material is not limited to stainless steel, should also be included in the scope of protection of this utility model.

[0075] In summary, this embodiment of the invention allows for the pressure relief channel 311 and pressure relief chamber 312 to be provided above the oil guide 321. When the aerosol generator is in a negative pressure environment, the e-liquid in the oil guide 321 flows upward along the pressure relief channel 311 and pressure relief chamber 312 to relieve pressure. When the aerosol generator is in a positive pressure environment, the e-liquid in the pressure relief channel 311 and pressure relief chamber 312 flows downward back to the oil guide 321.

[0076] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
