Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an atomizer and an electronic cigarette. Background Technology

[0002] Electronic cigarettes consist of two parts: an atomizer and a frame. The atomizer stores e-liquid and heats it to an atomized state, providing the user with vapor to inhale, while the frame provides electrical power.

[0003] In existing atomizers, the e-liquid reservoir is connected to the heating chamber only through an e-liquid guide hole. E-liquid can be transferred from the reservoir to the heating chamber, allowing it to be heated and atomized within the heating chamber, thus meeting the user's requirements for the amount of e-liquid they smoke.

[0004] However, as the e-liquid continues to be used, the e-liquid level in the reservoir gradually drops, creating a negative pressure in the air inside the reservoir. This negative pressure may prevent the e-liquid from flowing through the wicking hole to the heating chamber, resulting in a lack of e-liquid in the heating chamber and affecting the normal operation of the atomizer. Utility Model Content

[0005] The main purpose of this invention is to propose an atomizer and electronic cigarette that aims to solve the problem of negative pressure and ensure the normal use of the atomizer.

[0006] To achieve the above objectives, this utility model proposes an atomizer, the atomizer comprising:

[0007] Heating chamber, the heating chamber being used to heat e-liquid; and

[0008] An oil storage chamber is provided with a sealing element, which divides the oil storage chamber into a first chamber and a second chamber. The first chamber is connected to the outside air through an air hole, and the second chamber is connected to the heating chamber through an oil guide hole. The second chamber is used to store e-liquid.

[0009] The sealing element is movable within the oil storage chamber to change the size of the first chamber and the second chamber, thereby balancing the air pressure within the first chamber and the second chamber.

[0010] In one embodiment, the atomizer includes:

[0011] The inner housing contains a heating chamber and a smoke duct, the smoke duct communicating with the heating chamber to transport the smoke generated by the heating chamber along the smoke duct and allow it to be inhaled by the user. The inner housing also has an oil guide hole on its side wall.

[0012] The outer shell is fitted onto the outside of the inner shell. A gap is provided between the inner wall of the outer shell and the outer wall of the inner shell to form the oil storage cavity. The sealing element is fitted onto the outside of the inner shell and located between the inner shell and the outer shell. The outer shell has the air hole and the suction port on the side away from the oil guide hole. The suction port is connected to the smoke duct and the outside air.

[0013] In one embodiment, the sealing element includes an annular base and a plurality of protrusions. Along the height direction of the annular base, the plurality of protrusions are stacked on the sidewall of the annular base, and the opposite sides of each protrusion abut against the inner wall of the outer shell and the outer wall of the inner shell, respectively.

[0014] In one embodiment, the protrusion is made of an elastic material;

[0015] And / or, the annular base and the protrusion are integrally formed.

[0016] In one embodiment, the oil storage cavity is a cylindrical structure with an annular cross-section, and the oil guide holes include multiple holes arranged circumferentially along the inner shell.

[0017] In one embodiment, the plurality of oil guide holes are arranged at equal intervals.

[0018] In one embodiment, the inner wall of the outer casing is flush with the bottom wall of the oil guide hole on the side of the second chamber near the oil guide hole.

[0019] In one embodiment, the housing includes:

[0020] The main body comprises a first pipe segment and a second pipe segment connected to each other. The radius of the first pipe segment is smaller than the radius of the second pipe segment. The first pipe segment is fitted onto the inner shell, and a suction port is formed on the side of the first pipe segment facing away from the second pipe segment. A gap is provided between the second pipe segment and the inner shell. An opening is provided on the side of the second pipe segment facing away from the first pipe segment, and an air hole is provided on the side of the second pipe segment near the first pipe segment.

[0021] The base covers the opening, and the second pipe section, the inner shell and the base enclose the oil storage cavity to form the oil storage cavity. A slot is formed on the side of the base facing the oil storage cavity, and one end of the inner shell is inserted into the slot.

[0022] In one embodiment, the atomizer further includes a connecting assembly disposed on the side of the base opposite to the oil reservoir, and the atomizer is detachably connected to other components via the connecting assembly.

[0023] This utility model also proposes an electronic cigarette, which includes the atomizer described above.

[0024] The technical solution of this utility model divides the oil storage chamber into a first chamber and a second chamber by setting a seal inside the oil storage chamber. The first chamber is connected to the external environment through an air vent, and the second chamber is connected to the heating chamber through an oil guide hole. The movement of the seal balances the air pressure in the first and second chambers. As the e-liquid level in the second chamber gradually decreases, the air volume between the seal and the oil surface increases, creating a negative pressure. Meanwhile, the first chamber is connected to the outside air through the air vent, where the atmospheric pressure is relatively high. At this time, a pressure difference is formed between the first and second chambers. This pressure difference generates a downward thrust, pushing the seal downward. The movement of the seal compresses the air between the seal and the oil surface, reducing the air volume in the second chamber and gradually increasing the pressure until a new pressure balance is reached between the first and second chambers. This ensures that the e-liquid can be smoothly transported to the heating chamber through the oil guide hole. Furthermore, the air pressure between the first and second chambers remains in a balanced state, preventing air from mixing into the e-liquid and creating bubbles that would affect the e-liquid flow and atomization effect.

[0036] Electronic cigarettes consist of two parts: an atomizer and a frame. The atomizer stores e-liquid and heats it to an atomized state, providing the user with vapor to inhale, while the frame provides electrical power.

[0037] In existing atomizers, the e-liquid reservoir is connected to the heating chamber only through an e-liquid guide hole. E-liquid can be transferred from the reservoir to the heating chamber, allowing it to be heated and atomized within the heating chamber, thus meeting the user's requirements for the amount of e-liquid they smoke.

[0038] However, as the e-liquid continues to be used, the e-liquid level in the reservoir gradually drops, creating a negative pressure in the air inside the reservoir. This negative pressure may prevent the e-liquid from flowing through the wicking hole to the heating chamber, resulting in a lack of e-liquid in the heating chamber and affecting the normal operation of the atomizer.

[0039] The main purpose of this utility model is to propose an atomizer 100 and an electronic cigarette, which aims to solve the problem of negative pressure and ensure the normal use of the atomizer 100.

[0040] Please see Figures 1 to 4 In one embodiment of this utility model, the atomizer 100 includes a heating chamber 21 and an oil storage chamber 113. The heating chamber 21 is used to heat e-liquid. The oil storage chamber 113 is provided with a sealing member 3, which divides the oil storage chamber 113 into a first chamber 1131 and a second chamber 1132. The first chamber 1131 is connected to the outside air through an air hole 1121, and the second chamber 1132 is connected to the heating chamber 21 through an oil guide hole 23. The second chamber 1132 is used to store e-liquid. The sealing member 3 can move within the oil storage chamber 113 to change the size of the first chamber 1131 and the second chamber 1132 and balance the air pressure in the first chamber 1131 and the second chamber 1132.

[0041] In this embodiment, the atomizer 100 includes an oil storage chamber 113 and a heating chamber 21. A sealing element 3 is installed within the oil storage chamber 113 to divide it into a first chamber 1131 and a second chamber 1132. The first chamber 1131 is connected to the external environment through an air vent 1121 to ensure its internal air pressure is balanced with atmospheric pressure. The second chamber 1132 is connected to the heating chamber 21 through an oil guide hole 23. The movement of the sealing element 3 is used to balance the air pressure between the first chamber 1131 and the second chamber 1132. As the e-liquid level in the second chamber 1132 gradually decreases, the air volume between the sealing element 3 and the e-liquid level increases, creating a negative pressure. Meanwhile, the first chamber 1131 is connected to the outside air through the air vent 1121, where the atmospheric pressure is relatively high. At this time, a pressure difference is formed between the first chamber 1131 and the second chamber 1132. This pressure difference generates a downward thrust, pushing the sealing element 3 downward. The movement of the seal 3 compresses the air between the seal 3 and the e-liquid surface, reducing the air volume in the second chamber 1132 and gradually increasing the pressure until a new pressure equilibrium is reached between the first chamber 1131 and the second chamber 1132. This ensures that the e-liquid can be smoothly transported to the heating chamber 21 through the wicking hole 23. Furthermore, the pressure between the first chamber 1131 and the second chamber 1132 remains in equilibrium, preventing pressure fluctuations from causing air to mix into the e-liquid and generate bubbles, which would affect the e-liquid's flow and atomization effect.

[0042] Understandably, the vent 1121 is mainly used to connect the first chamber 1131 with the outside air. Therefore, the size of the vent 1121 does not need to be too large, so as to prevent impurities from entering the first chamber 1131. Of course, if it is necessary to make the vent 1121 larger to meet other purposes, a filter screen or dust cover can be installed inside the vent 1121 to prevent external impurities from entering the first chamber 1131 through the vent 1121.

[0043] In one implementation, please refer to Figure 2 and Figure 3 The atomizer 100 includes an inner shell 2 and an outer shell 1. The inner shell 2 has a heating chamber 21 and a smoke channel 22 inside. The smoke channel 22 is connected to the heating chamber 21 so that the smoke generated by the heating chamber 21 is transported along the smoke channel 22 and inhaled by the user. The side wall of the inner shell 2 is provided with an oil guide hole 23. The outer shell 1 is fitted on the outside of the inner shell 2. There is a gap between the inner wall of the outer shell 1 and the outer wall of the inner shell 2 to form an oil storage chamber 113. The sealing member 3 is fitted on the outside of the inner shell 2 and is located between the inner shell 2 and the outer shell 1. The side of the outer shell 1 away from the oil guide hole 23 is provided with an air hole 1121 and an inlet 1111. The inlet 1111 is connected to the smoke channel 22 and the outside air.

[0044] In this embodiment, the atomizer 100 has a double-shell structure, including an inner shell 2 and an outer shell 1. The inner shell 2 is provided with a heating chamber 21 and a vapor channel 22. An oil storage chamber 113 is formed between the outer shell 1 and the inner shell 2, so that the oil storage chamber 113 can surround the heating chamber 21. The oil guide hole 23 on the side wall of the inner shell 2 allows the e-liquid in the oil storage chamber 113 to flow evenly into the heating chamber 21, ensuring the atomization effect. The sealing member 3 is sleeved on the outside of the inner shell 2 and located between the inner shell 2 and the outer shell 1. The movement of the sealing member 3 balances the air pressure in the first chamber 1131 and the second chamber 1132 in the oil storage chamber 113, ensuring that the e-liquid can flow smoothly. The outer shell 1 has an air hole 1121 and a suction port 1111 on the side away from the oil guide hole 23. The air hole 1121 is used to balance the air pressure, and the suction port 1111 connects the vapor channel 22 to the outside, making it convenient for the user to inhale.

[0045] Understandably, when the e-liquid reservoir 113 is arranged around the heating chamber 21, it improves space utilization, ensuring that more e-liquid can be stored within a limited space. At the same time, this layout also enhances the structural stability of the atomizer 100, making it more reliable during use and reducing the risk of damage caused by external impacts.

[0046] In one implementation, please refer to Figure 3 The sealing element 3 includes an annular base 31 and a plurality of protrusions 32. Along the height direction of the annular base 31, the plurality of protrusions 32 are stacked on the side wall of the annular base 31, and the opposite sides of each protrusion 32 abut against the inner wall of the outer shell 1 and the outer wall of the inner shell 2, respectively.

[0047] In this embodiment, the annular base 31 provides a supporting foundation for the seal 3, ensuring its stable movement within the oil storage cavity 113. Along the height direction of the annular base 31, multiple protrusions 32 are stacked on the sidewalls of the annular base 31. The two sides of each protrusion 32 are in close contact with the inner wall of the outer shell 1 and the outer wall of the inner shell 2, respectively, forming a sealing effect to prevent e-liquid leakage.

[0048] Understandably, the presence of the protrusion creates a gap between the annular base 31 and the inner wall of the outer shell 1, ensuring that the seal 3 can move within the oil storage cavity 113. Without the protrusion, the sidewall of the annular base 31 would completely abut against the inner wall of the outer shell 1 and the outer wall of the inner shell 2, increasing the contact area and weakening the movement of the seal 3 within the oil storage cavity 113, thus failing to guarantee pressure balance in the first chamber 1131 and the second chamber 1132. Furthermore, by providing multiple protrusions 32 to increase the contact area, the sealing performance of the oil storage cavity 113 and the stability of pressure balance are ensured.

[0049] Alternatively, the protrusion 32 can be stacked on the inner or outer wall of the annular base 31. In this case, the seal 3 seals the first chamber 1131 and the second chamber 1132 through the side wall of one side of the annular base 31 and the protrusion 32 on the other side. This ensures both sealing performance and allows the seal 3 to move flexibly to balance the air pressure.

[0050] In one implementation, please refer to Figure 3 The protrusion 32 is made of elastic material.

[0051] In this embodiment, the protrusion 32 is made of an elastic material, which allows the protrusion 32 to achieve a seal within the oil storage cavity 113 while ensuring the smooth movement of the sealing element 3 during e-liquid consumption. The elastic material can deform under pressure, tightly fitting the inner wall of the oil storage cavity 113 and the outer wall of the inner shell 2 to ensure sealing. At the same time, the elastic material allows the sealing element 3 to adjust its position in a timely manner when the air pressure changes, maintaining the air pressure balance between the first chamber 1131 and the second chamber 1132.

[0052] Alternatively, the elastic material can be food-grade silicone, rubber, or polyurethane, etc.

[0053] In one implementation, please refer to Figure 3 The annular base 31 and the protrusion 32 are integrally formed.

[0054] In this embodiment, the annular base 31 and the protrusion 32 are manufactured by an integral molding process, which not only simplifies the production process and improves production efficiency, but also enhances the sealing performance of the seal 3 and prevents the protrusion 32 from sliding relative to the annular base 31.

[0055] In one implementation, please refer to Figure 2 and Figure 4 The oil storage cavity 113 is a cylindrical structure, and the cross-section of the oil storage cavity 113 is annular. The oil guide hole 23 includes multiple holes, which are arranged along the circumference of the inner shell 2.

[0056] In this embodiment, the oil storage chamber 113 has a cylindrical structure and a circular cross-section, allowing it to uniformly surround the inner shell 2 and provide a stable e-liquid storage space. Multiple wicking holes 23 are distributed circumferentially along the inner shell 2, ensuring that e-liquid can flow into the heating chamber 21 from different directions, improving e-liquid supply efficiency. Understandably, the circular oil storage chamber 113 structure and the circumferentially distributed wicking holes 23 not only improve e-liquid storage efficiency and supply stability but also enhance the symmetry of the atomizer 100 and improve its aesthetics.

[0057] Optionally, the cross-section of the oil storage chamber 113 can also be configured in other shapes, such as square, triangular, or other irregular shapes. However, it is necessary to ensure that the oil storage chamber 113 is a cylindrical structure, that is, the cross-sectional shape and size of the oil storage chamber 113 are always the same. This ensures that the sealing member 3 can always separate the first chamber 1131 and the second chamber 1132 during the movement of the sealing member 3, preventing air from directly entering the second chamber 1132 and coming into contact with the e-liquid. Therefore, the cross-sectional shape of the oil storage chamber 113 is not specifically limited here.

[0058] In one implementation, please refer to Figure 2 Multiple oil guide holes 23 are set at equal intervals.

[0059] In this embodiment, multiple oil guide holes 23 are arranged at equal intervals along the circumference of the inner shell 2. This ensures that the path of e-liquid flowing from the oil storage chamber 113 to the heating chamber 21 is uniform and consistent, avoiding uneven e-liquid supply caused by uneven positions of the oil guide holes 23. It can be understood that this layout of the oil guide holes 23 optimizes the flow path of the e-liquid and improves the stability of e-liquid supply.

[0060] In one implementation, please refer to Figure 2 The second chamber 1132 is located on the side near the oil guide hole 23, and the inner wall of the outer shell 1 is flush with the bottom wall of the oil guide hole 23.

[0061] In this embodiment, by setting the inner wall of the outer shell 1 flush with the bottom wall of the oil guide hole 23 on the side of the second chamber 1132 close to the oil guide hole 23, the smooth flow of e-liquid between the oil storage chamber 113 and the heating chamber 21 is ensured, the residue of e-liquid in the oil storage chamber 113 is reduced, and the utilization rate of e-liquid is improved.

[0062] In one implementation, please refer to Figure 2 The outer shell 1 includes a main body 11 and a base 12. The main body 11 has a first pipe segment 111 and a second pipe segment 112 connected to each other. The radius of the first pipe segment 111 is smaller than the radius of the second pipe segment 112. The first pipe segment 111 is fitted onto the inner shell 2, and a suction port 1111 is formed on the side of the first pipe segment 111 facing away from the second pipe segment 112. There is a gap between the second pipe segment 112 and the inner shell 2. An opening is provided on the side of the second pipe segment 112 facing away from the first pipe segment 111. An air hole 1121 is provided on the side of the second pipe segment 112 near the first pipe segment 111. The base 12 covers the opening. The second pipe segment 112, the inner shell 2 and the base 12 enclose an oil storage cavity 113. A slot 121 is formed on the side of the base 12 facing the oil storage cavity 113. One end of the inner shell 2 is inserted into the slot 121.

[0063] In this embodiment, the outer shell 1 includes a main body 11 and a base 12. The main body 11 further includes a first tube segment 111 and a second tube segment 112. The first tube segment 111 has a smaller radius, allowing it to fit tightly onto the outside of the inner shell 2. A suction port 1111 is provided on the side of the first tube segment 111 facing away from the second tube segment 112 for the user to inhale vapor. The second tube segment 112 has a larger radius and is spaced from the inner shell 2. An opening is provided on the side of the second tube segment 112 facing away from the first tube segment 111 for easy filling with e-liquid. The base 12 is installed at the opening and, together with the second tube segment 112 and the inner shell 2, forms an oil storage cavity 113. A slot 121 is designed on the side of the base 12 facing the oil storage cavity 113, allowing one end of the inner shell 2 to be inserted into the slot 121 for installation.

[0064] Optionally, the base 12 and the second tube segment 112 are connected by a detachable structure, such as threads or clips, to facilitate the replenishment of e-liquid and the cleaning of the e-liquid reservoir 113. Optionally, the first tube segment 111 and the second tube segment 112 can be integrally formed or connected by a detachable structure.

[0065] In one implementation, please refer to Figure 2 and Figure 4 The atomizer 100 also includes a connecting component 4, which is located on the side of the base 12 facing away from the oil reservoir 113. The atomizer 100 is detachably connected to other components through the connecting component 4.

[0066] In this embodiment, the atomizer 100 also includes a connecting component 4, which is installed on the side of the base 12 facing away from the oil storage chamber 113. This component is used to enable the atomizer 100 to be detachably connected to other components. Users can disassemble and replace the atomizer 100 as needed, or combine it with other components, thereby enhancing the versatility of the product.

[0067] Optionally, the connecting component 4 can be connected by magnetic attraction, threaded connection or snap-fit ​​connection to achieve a detachable connection.

[0068] In one implementation, please refer to Figure 2 and Figure 4 The connecting component 4 includes a first connecting part 41, a second connecting part 42, and an insulating member 43. The second connecting part 42 is sleeved on the outside of the first connecting part 41 and is detachably connected to other components. The insulating member 43 is disposed between the first connecting part 41 and the second connecting part 42. The first connecting part 41 and the second connecting part 42 are electrically connected to the heating element, respectively.

[0069] In this embodiment, the connecting component 4 is not only used for structural connection but also for transmitting electrical energy. The connecting component 4 includes a first connecting portion 41, a second connecting portion 42, and an insulating member 43. The second connecting portion 42 is sleeved outside the first connecting portion 41, forming a protective and supporting base, while also enabling detachable connection with other components. The insulating member 43 is installed between the first connecting portion 41 and the second connecting portion 42 to ensure electrical insulation between them and prevent short circuits. Furthermore, the first connecting portion 41 and the second connecting portion 42 are electrically connected to the heating element to form a stable circuit loop. When the atomizer 100 is connected to other components, these components can transmit electrical energy, thereby providing a reliable power supply to the heating element.

[0070] Optionally, the insulation element 43 can be ceramic or polytetrafluoroethylene to ensure good insulation performance in high temperature and humid environments.

[0071] In one implementation, please refer to Figure 1 The outer wall of the outer shell 1 is provided with a grip groove 1122, which is used for gripping by the hand.

[0072] In this embodiment, the outer wall of the outer shell 1 is also provided with a grip groove 1122, thereby providing users with a more comfortable and stable grip experience.

[0073] Understandably, the shape and size of the grip groove 1122 can be optimized according to ergonomic principles to accommodate different users' hand shapes and gripping habits. By adding the grip groove 1122, users can obtain a better anti-slip effect when holding the atomizer 100, reducing the risk of accidental slippage, and also improving the comfort of using the atomizer 100.

[0074] Optionally, the surface of the grip groove 1122 may be textured or have an anti-slip material added to further improve grip stability.
