Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to a fuel dispenser and an electronic atomization device. Background Technology

[0002] Electronic atomizers increase the number of vape cycles by adding a fuel bottle to facilitate the supply of fuel to the working fuel tank or atomization chamber.

[0003] For oil bottles that supply oil by pressing a button, the oil outlet is connected to the button. When the button moves up and down, the oil outlet moves synchronously, allowing the aerosol product inside the oil bottle to flow out through the oil outlet. However, the movement of the oil outlet by the button affects the stability of the seal at the oil outlet, making it easy for oil to leak out, which is very inconvenient to use. Utility Model Content

[0004] This application provides a fuel bottle and an electronic atomizing device, which can solve the problem of easy fuel leakage during fuel supply.

[0005] To solve the above-mentioned technical problems, this application provides an oil supply bottle, including: a bottle body, a pressing bracket, a movable plug, a one-way valve, and a piston assembly.

[0006] The bottle body has a bottle mouth at one end and an air inlet at the other end;

[0007] The pressing bracket covers the bottle mouth, the pressing bracket has a cavity inside, the pressing bracket has an opening at one end inside the bottle mouth, and the pressing bracket has an oil outlet on its side.

[0008] The movable plug is movably disposed inside the bottle body, and the side of the movable plug abuts against the inner wall of the bottle body to form a receiving cavity for accommodating aerosol products. As the aerosol products gradually decrease, the movable plug moves synchronously to reduce the volume of the receiving cavity.

[0009] The one-way valve is located at the opening, allowing the aerosol product in the receiving cavity to flow into the cavity in one direction.

[0010] One end of the piston assembly is placed inside the cavity, and the other end is placed outside the pressing bracket. When the piston assembly is in the pressing state, the oil outlet is connected to the cavity, the one-way valve covers the opening, and the aerosol product in the cavity flows out through the oil outlet. When the piston assembly is in the reset state, the oil outlet is closed, the one-way valve opens the opening, and part of the aerosol product in the receiving cavity flows into the cavity. The moving plug moves synchronously toward one end of the one-way valve.

[0011] In one possible embodiment of this application, the pressing bracket includes: a cover and a support. The cover is closed to the bottle mouth, the opening and the cavity are provided in the cover, and the support is provided at the end of the cover away from the bottle body. The support is provided with the oil outlet.

[0012] In one possible embodiment of this application, the support member is provided with a mounting groove, and the end of the cap member away from the bottle body is placed in the mounting groove. An oil guiding channel is formed at the connection between the cap member and the support member. One end of the oil guiding channel is connected to the oil outlet, and the other end is connected to the end of the cavity away from the one-way valve.

[0013] In one possible embodiment of this application, the oil supply bottle further includes an oil supply needle tube, one end of which is placed inside the oil outlet.

[0014] In one possible embodiment of this application, the piston assembly includes: a pressing part, an elastic element, and a sealing plug. The pressing part is connected to the sealing plug, and the sealing plug is located within the cavity. When the pressing part is in a pressed state, the sealing plug moves toward the opening and opens the oil guide channel. When the pressing part is in a reset state, the sealing plug closes the oil guide channel and moves away from the opening. One end of the elastic element abuts against the pressing part, and the other end abuts against the support member, so that the pressing part can be reset.

[0015] In one possible embodiment of this application, the pressing part includes: a button and a connecting rod. The sealing plug has a clearance hole. One end of the connecting rod is connected to the button, and the other end passes through the clearance hole. The end of the connecting rod is provided with a cover plate. When the pressing part is in the reset state, the cover plate covers the clearance hole. When the pressing part is in the pressed state, the cover plate opens the clearance hole. One end of the button located in the cavity abuts against the sealing plug and drives the sealing plug to move. One end of the clearance hole communicates with the cavity, and the other end communicates with the oil guide channel.

[0016] In one possible embodiment of this application, the cover is provided with a mounting hole, the support is provided with a mounting channel, one end of the mounting channel is placed in the cavity through the mounting hole, and part of the button is movably disposed in the mounting channel to abut against or move away from the sealing plug.

[0017] In one possible embodiment of this application, the piston assembly further includes a sealing ring disposed at the contact point between the button and the mounting channel.

[0018] This application also proposes an electronic atomizing device, comprising: an atomizer, a power supply component, a driving component, and an oil supply bottle, wherein the power supply component is electrically connected to the driving component and the atomizer, the oil supply bottle is the oil supply bottle described above, the atomizer includes an atomizing chamber, and the oil outlet is connected to the atomizing chamber.

[0019] In one possible embodiment of this application, the fuel bottle is detachably connected to the atomizer.

[0020] The oil supply bottle of this application comprises a bottle body, a pressing bracket, a movable plug, a one-way valve, and a piston assembly. The bottle body has a bottle opening at one end and an air inlet at the other. The pressing bracket covers the bottle opening and has a cavity inside. One end of the pressing bracket located inside the bottle opening has an opening, and the side of the pressing bracket has an oil outlet. The movable plug is movably disposed within the bottle body, and its side circumferentially abuts against the inner wall of the bottle body to form a receiving cavity for accommodating aerosol products. As the aerosol products gradually decrease, the movable plug moves synchronously to reduce the volume of the receiving cavity. The one-way valve is located at the opening, allowing the receiving cavity to... The aerosol product flows unidirectionally into the cavity. One end of the piston assembly is placed inside the cavity, and the other end is placed outside the pressing bracket. When the piston assembly is in the pressing state, the oil outlet connects to the cavity, the one-way valve closes the opening, and the aerosol product in the cavity flows out through the oil outlet. When the piston assembly is in the reset state, the oil outlet closes, the one-way valve opens the opening, and a portion of the aerosol product in the receiving cavity flows into the cavity. The moving plug moves synchronously towards one end of the one-way valve. Thus, as the amount of aerosol product in the bottle decreases, the negative pressure increases, driving the moving plug to move, ultimately maintaining a stable pressure inside the bottle. This prevents insufficient oil supply and eliminates the need for a guide tube inside the oil bottle, reducing costs and improving assembly efficiency. Furthermore, by setting the oil outlet and cavity on the pressing bracket, when the piston assembly is pressed, the oil outlet can supply oil. The positions of the oil outlet and cavity remain unchanged, and the connection between the oil outlet and the external atomizer is also more stable, thus making it less prone to oil leakage when the oil supply bottle supplies oil.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features.

[0031] In this application, the term "exemplary" is used to mean "used as an example, illustration, or description." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0032] Please see Figures 1 to 4 In one embodiment, this application proposes an oil supply bottle 100, comprising: a bottle body 10, a pressing bracket 20, a movable plug 30, a one-way valve 40, and a piston assembly 50.

[0033] One end of the bottle body 10 is provided with a bottle mouth 11, and the other end is provided with an air inlet 12;

[0034] The pressing bracket 20 is closed to the bottle mouth 11. The pressing bracket 20 has a cavity 211 inside. The end of the pressing bracket 20 located inside the bottle mouth 11 has an opening 212. The side of the pressing bracket 20 has an oil outlet 221.

[0035] The movable plug 30 is movably disposed inside the bottle body 10. The side of the movable plug 30 abuts against the inner wall of the bottle body 10 to form a receiving cavity 13 for containing aerosol products. As the aerosol products gradually decrease, the movable plug 30 moves synchronously to reduce the volume of the receiving cavity 13.

[0036] A one-way valve 40 is provided at the opening 212, allowing the aerosol product in the receiving cavity 13 to flow into the cavity 211 in one direction.

[0037] One end of the piston assembly 50 is placed inside the cavity 211, and the other end is placed outside the pressing bracket 20. When the piston assembly 50 is in the pressing state, the oil outlet 221 connects to the cavity 211, the one-way valve 40 closes the opening 212, and the aerosol product in the cavity 211 flows out through the oil outlet 221. When the piston assembly 50 is in the reset state, the oil outlet 221 is closed, the one-way valve 40 opens the opening 212, and part of the aerosol product in the receiving cavity 13 flows into the cavity 211. The moving plug 30 moves synchronously to one end of the one-way valve 40.

[0038] The bottle body 10 can be made of transparent material, or more specifically, transparent plastic or transparent glass. There can be multiple air inlets 12, which are connected to the outside of the oil supply bottle 100. This prevents negative pressure from forming between the moving plug 30 and the bottom of the bottle body 10, thus ensuring that the moving plug 30 moves stably as the aerosol product in the receiving cavity 13 decreases.

[0039] The connection between the pressing bracket 20 and the bottle mouth 11 can be made by interference fit, which can prevent oil leakage at the connection.

[0040] The movable stopper 30 can be made of silicone. The side of the movable stopper 30 can elastically abut against the inner wall of the receiving cavity 13, and the abutment between the movable stopper 30 and the inner wall of the receiving cavity 13 can form at least two annular structures, thereby further preventing oil leakage at the connection between the movable stopper 30 and the inner wall of the receiving cavity 13. Furthermore, a slide can be provided inside the bottle body 10, and the edge of the movable stopper 30 can be located in the slide, thereby allowing the movable stopper 30 to move stably and preventing oil leakage at the contact point.

[0041] The one-way valve 40 can be made of silicone. One side of the one-way valve 40 can be provided with an elastic plate. When the aerosol product, such as e-liquid, in the receiving cavity 13 enters the cavity 211, the elastic plate is opened to open the opening 212. When the e-liquid in the cavity 211 is pressed by the piston assembly 50 to flow out of the oil outlet 221, the elastic plate is covered by the pressure in the cavity 211 to close the opening 212, preventing the e-liquid in the cavity 211 from entering the receiving cavity 13.

[0042] The piston assembly 50 can move up and down, thereby drawing e-liquid from the receiving cavity 13 into the cavity 211, and then allowing the e-liquid in the cavity 211 to flow out through the outlet 221. As the piston assembly 50 moves up and down repeatedly, the e-liquid in the receiving cavity 13 continuously flows out through the outlet 221 to supply e-liquid to the atomizer 70.

[0043] As the aerosol product inside the bottle 10 decreases, the negative pressure increases, driving the moving plug 30 to move, ultimately maintaining a stable pressure inside the bottle 10. This prevents uneven oil supply and eliminates the need for a guide tube inside the bottle 10, reducing costs and improving assembly efficiency. Furthermore, by setting the oil outlet 221 and cavity 211 on the pressing bracket 20, when the piston assembly 50 is pressed, the oil outlet 221 can supply oil. The positions of the oil outlet 221 and cavity 211 remain fixed, and the connection between the oil outlet 221 and the external atomizer 70 is more stable, thus making it less prone to oil leakage when the oil supply bottle 100 supplies oil.

[0044] Please see Figure 3 and Figure 4 In one embodiment, the pressing bracket 20 includes a cover 21 and a support 22. The cover 21 covers the bottle neck 11, and an opening 212 and a cavity 211 are provided in the cover 21. The support 22 is located at the end of the cover 21 away from the bottle body 10, and the support 22 has an oil outlet 221. The connection between the cover 21 and the support 22 can be interlocked. The combination of the cover 21 and the support 22 facilitates the assembly of the one-way valve 40 and the piston assembly 50, improving assembly efficiency.

[0045] Please see Figure 3 and Figure 4 In one embodiment, the support member 22 is provided with a mounting groove 222. The end of the cap 21 away from the bottle body 10 is placed in the mounting groove 222. An oil guiding channel 213 is formed at the connection between the cap 21 and the support member 22. One end of the oil guiding channel 213 is connected to the oil outlet 221, and the other end is connected to the end of the cavity 211 away from the one-way valve 40. The mounting groove 222 makes the connection between the support member 22 and the cap 21 more compact, reduces the space occupied by the pressing bracket 20, and thus makes the oil supply bottle 100 smaller and easier to carry.

[0046] Please see Figure 3 and Figure 4 In one embodiment, the fuel bottle 100 further includes a fuel supply needle 60, one end of which is placed inside the fuel outlet 221. The fuel supply needle 60 may be made of metal; in one embodiment, the fuel supply needle 60 is a steel pipe, which facilitates the connection of one end of the fuel supply needle 60 into the fuel outlet 221, and the other end can be quickly connected to the atomizer 70, improving assembly efficiency.

[0047] Please see Figure 3 and Figure 4In one embodiment, the piston assembly 50 includes: a pressing part 51, an elastic member 52, and a sealing plug 53. The pressing part 51 is connected to the sealing plug 53, which is located in the cavity 211. When the pressing part 51 is in the pressing state, the sealing plug 53 moves toward the opening 212 and opens the oil guide channel 213. When the pressing part 51 is in the reset state, the sealing plug 53 closes the oil guide channel 213 and moves away from the opening 212. One end of the elastic member 52 abuts against the pressing part 51, and the other end abuts against the support member 22, so that the pressing part 51 can be reset.

[0048] The elastic element 52 can be a linear spring, allowing the pressing part 51 to spring back to its reset state after being pressed down. The sealing plug 53 can be integrally formed with the pressing part 51, simplifying the structure of the oil supply bottle 100 and making assembly easier. Furthermore, when the pressing part 51 is in the reset state, the sealing plug 53 closes the oil guide channel 213, preventing e-liquid in the cavity 211 from flowing out through the oil outlet 221, thus improving the stability of the oil supply from the oil supply bottle 100.

[0049] Please see Figure 3 and Figure 4 In one embodiment, the pressing part 51 includes: a button 511, a connecting rod 512, and a sealing plug 53 having a clearance hole 531. One end of the connecting rod 512 is connected to the button 511, and the other end passes through the clearance hole 531. The end of the connecting rod 512 is provided with a cover plate 513. When the pressing part 51 is in the reset state, the cover plate 513 covers the clearance hole 531. When the pressing part 51 is in the pressing state, the cover plate 513 opens the clearance hole 531. One end of the button 511 located in the cavity 211 abuts against the sealing plug 53 and drives the sealing plug 53 to move. One end of the clearance hole 531 communicates with the cavity 211, and the other end communicates with the oil guide channel 213.

[0050] The button 511 may have a groove, and one end of the connecting rod 512 is placed in the groove, thereby connecting the connecting rod 512 and the button 511. The elastic element 52 can be sleeved on the connecting rod 512, with one end of the elastic element 52 abutting against the button 511 and the other end abutting against the support member 22. The clearance hole 531 is located in the middle of the sealing plug 53. The connecting rod 512 passes through the clearance hole 531. When the pressing part 51 moves from the pressing state to the reset state, the cover plate 513 covers the clearance hole 531, and at the same time, the cover plate 513 can move the sealing plug 53 to the reset state simultaneously, thereby simplifying the connection structure of the pressing part 51.

[0051] Please see Figure 3 and Figure 4In one embodiment, the cover 21 is provided with a mounting hole 214, and the support 22 is provided with a mounting channel 223. One end of the mounting channel 223 is placed in the cavity 211 through the mounting hole 214. Some buttons 511 are movably disposed in the mounting channel 223 to abut against or move away from the sealing plug 53.

[0052] The mounting channel 223 abuts tightly against the inner wall of the mounting hole 214, preventing oil leakage at the connection between the cover 21 and the support 22. The button 511 abuts against the inner wall of the mounting channel 223 with a clearance fit. Furthermore, the piston assembly 50 also includes a sealing ring 51, located at the abutment between the button 511 and the mounting channel 223, thereby achieving an elastic seal between the button 511 and the mounting channel 223 to prevent oil leakage at the abutment. Even further, multiple sealing rings 51 can be used, fitted onto the side of the button 511, with the outer side of the sealing ring 51 elastically abutting against the inner wall of the mounting channel 223. This allows the button 511 to move back and forth within the mounting channel 223 while reducing the risk of oil leakage and improving the reliability of the oil supply bottle 100.

[0053] Please see Figure 5 This application also proposes an electronic atomizing device, including: an atomizer 70, a power supply component 80, a drive component 90, and a fuel bottle 100. The power supply component 80 is electrically connected to the drive component 90 and the atomizer 70. The fuel bottle 100 is the aforementioned fuel bottle 100. The atomizer 70 includes an atomization chamber, and an oil outlet 221 communicates with the atomization chamber. The power supply component 80 may include a battery, which may have a detachable connection structure for easy battery recycling. The atomizer 70 is equipped with a heating wire for heating and atomizing the infiltrated aerosol product, such as e-liquid, for inhalation by the user. The drive component 90 may be a motor, which is connected to the piston assembly 50 of the fuel bottle 100 via a gear structure. When the drive component 90 rotates, it drives the piston assembly 50 to press and reset, thereby enabling the fuel bottle 100 to supply fuel to the atomizer 70. Furthermore, since the electronic atomizing device uses the aforementioned fuel supply bottle 100, it also possesses all the beneficial effects brought about by the aforementioned fuel supply bottle 100, which will not be elaborated upon here.

[0054] Please see Figure 5 In one embodiment, the fuel bottle 100 is detachably connected to the atomizer 70. The fuel bottle 100 can be quickly connected to the atomizer 70 via the fuel supply needle 60, thereby improving the assembly efficiency of the fuel bottle 100. Furthermore, the fuel bottle 100 is detachable, making it convenient for users to replace the fuel bottle 100, thus extending the service life of the electronic atomizing device and making it more convenient to use.

For the specific implementation of each of the above units or structures, please refer to the previous method embodiments, which will not be repeated here.

[0056] The above provides a detailed description of the fuel bottle and electronic atomizing device provided in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application.
