Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to a high-efficiency heat-not-burn electronic cigarette. Background Art

[0002] Heat-not-burn e-cigarettes use the principle of low-temperature heat-not-burn to heat the tobacco leaves just enough to release flavor without igniting. As an alternative to traditional cigarettes, they remove most of the harmful substances in traditional cigarettes, effectively reducing the harm to smokers' health.

[0003] Currently available heat-not-burn electronic cigarettes usually have a heating body, which mainly includes internally heated ceramic heating plates and heating needles, or externally heated fixed heating tubes and heating pots, as well as internal and external mixed heating forms. By setting the heating body on the outside or inside of the cigarette body and energizing the heating body, the cigarette body can be heated at low temperature without burning.

[0004] However, in actual use, the conventional external heating body is a cylindrical structure with a fixed diameter. The cigarette body is inserted into the cylindrical structure to heat the cigarette body. When the heating body is working, as the tobacco oil in the cigarette body evaporates, the cigarette body will shrink and become thinner, thereby creating a larger gap between the inner wall of the heating body and the outer wall of the cigarette body, reducing the heat conduction of the heating body and increasing power loss. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a high-efficiency heat-not-burn electronic cigarette to solve the technical problems in the prior art that the gap between the inner wall of the heating body and the outer wall of the cigarette body becomes larger, the heat conductivity of the heating body is reduced, and the power loss is increased.

[0006] The present invention provides a high-efficiency heat-not-burn electronic cigarette suitable for heating a cigarette body, comprising:

[0007] The heating body is configured as a hollow cylinder with one end open, and the smoke body extends into the heating body from the opening. The heating body is elastic. When the smoke body is placed into the heating body, the inner wall of the heating body and the smoke body are in close contact when the electronic cigarette is started. When the smoke body becomes thinner, the inner wall of the heating body shrinks and deforms inward to maintain close contact with the outer wall of the smoke body.

[0008] In one embodiment, the heating body has a first state and a second state. When in the first state, the inner wall of the heating body is in close contact with the outer wall of the cigarette body. When the heating body is in the second state, a gap is left between the inner wall of the heating body and the outer wall of the cigarette body. The heating body also includes a driving member, which drives the inner wall of the heating body to deform toward or away from the cigarette body, so that the heating body is switched between the first state and the second state.

[0009] In one embodiment, it further includes an upper shell and a lower shell, the heating body is arranged on the side of the lower shell facing the upper shell, the upper shell is arranged to be a hollow cylinder with openings at both ends, the upper shell is sleeved on the heating body and connected to the lower shell, and the smoke body extends into the heating body through the opening of the upper shell.

[0010] In one embodiment, the heating body includes a connecting section and a plurality of abutting sections. The abutting section is annularly arranged on a side of the connecting section facing the cigarette body and one end is connected to the connecting section. When the cigarette body is inserted into the heating body, the cigarette body is located between the plurality of abutting sections.

[0011] The plurality of abutment sections are open on one side facing away from the connecting section, and a pushing member is provided at the abutment section, which drives the abutment section to deform toward the cigarette body until the abutment section and the outer wall of the cigarette body are tightly abutted, so that the heating body is in the first state.

[0012] In one embodiment, the pushing member includes a pressure ring and an elastic member mounted on the heating body. The elastic force of the elastic member drives the pressure ring to move away from the connecting section, and the pressure ring drives multiple abutting sections to deform toward the cigarette body until the abutting sections and the outer wall of the cigarette body are tightly pressed against each other, and the heating body is in the first state.

[0013] In one embodiment, the upper shell is rotatably connected to the lower shell with the axis of the lower shell as the rotation axis, the driving member includes an inclined slope provided on the pressure ring, and the slope extends along the rotation path of the upper shell. A pressure block is provided in the upper shell, and when the upper shell is rotatably connected to the lower shell, the pressure block and the slope interfere with each other;

[0014] When the upper shell rotates, the pressing block slides on the slope along the length direction of the slope, pushing the pressing ring to move toward the connecting section, so that the heating body switches from the first state to the second state.

[0015] In one embodiment, a bracket is further included, which is in the shape of a tube with an open end. The bracket is sleeved on the heating body and a space is left between the bracket and the heating body for placing the elastic member. The bracket is provided with a guide bar on the side facing the pressure ring, and the guide bar extends along the moving direction of the pressure ring. A guide hole corresponding to the guide bar is provided on the pressure ring, and the guide bar extends into the guide hole and slides with the guide hole.

[0016] In one embodiment, the heating body is configured as an open circular tube, the smoke body extends into the circular tube, and a slit is provided on the side wall of the circular tube. The slit is provided along the length direction of the circular tube and passes through both ends of the circular tube.

[0017] In an initial state, the diameter of the circular tube is smaller than the diameter of the cigarette body. When the cigarette body extends into the circular tube, the cigarette body and the inner wall of the circular tube are pressed tightly.

[0018] In one embodiment, the driving member includes a sliding block that slides along the length direction of the heating body, and a first pushing block is provided on the circular tube wall on both sides of the gap, and the first pushing block extends along the length direction of the heating body, and the opposite side walls of the first pushing block are inclined and inclined in opposite directions, and the sliding block is provided with two second pushing blocks corresponding to the first pushing block, and the second pushing blocks are located at the first pushing block and abut against the inclined side walls of the first pushing block;

[0019] When the sliding block is pushed to slide on the heating body, the second pushing block slides and collides along the length direction of the first pushing block, so that the second pushing block pushes the two first pushing blocks to move closer to and away from each other, the gap in the circular tube becomes larger or smaller, and the heating body switches between the first state and the second state.

[0020] In one embodiment, a switch key is slidingly provided on the upper shell, and a linkage block is provided on the side of the switch key facing the slider. The linkage block is inserted into the sliding block. When the switch key slides, it drives the sliding block to slide along the length direction of the heating body.

[0022] The high-efficiency heat-not-burn electronic cigarette provided by the present invention has an elastic heating body. When the cigarette body is placed in the heating body, the inner wall of the heating body and the outer wall of the cigarette body are tightly attached. When the cigarette body is heated, as the cigarette oil evaporates, the cigarette body becomes thinner. At this time, the inner wall of the heating body deforms and contracts toward the cigarette body and is tightly attached to the outer wall of the cigarette body again. The heating body can automatically clamp the cigarette body at all times, so that the heat of the heating body can be fully and directly conducted to the cigarette body, reducing battery energy consumption, increasing usage time with the same battery capacity, and improving the user experience.

[0043] In addition, the technical features involved in different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

[0044] Example 1

[0045] Reference Figure 1-Figure 7 As shown, the present invention provides a high-efficiency heat-not-burn electronic cigarette, which is suitable for heating a cigarette body 1. The cigarette body 1 can be set as a cigarette. The high-efficiency heat-not-burn electronic cigarette includes a heating body 2, which is set as a hollow cylinder with openings at both ends. The cigarette body 1 extends into the heating body 2 from the top opening. When powered on, the heating body 2 will heat and heat the cigarette body 1 without burning, so that the tobacco leaves in the cigarette body 1 are just heated to a degree that emits flavor but does not ignite. Since the tobacco oil on the internal tobacco leaves or tobacco shreds evaporates during the heating process of the cigarette body 1, the volume of the cigarette body 1 will shrink, and the gap between the heating body 2 and the cigarette body 1 will expand, thereby reducing the heat conduction of the heating body 2 and increasing power loss.

[0046] In order to improve the heat conduction of the heating body 2 and reduce power loss, the heating body 2 is set to be elastic. When the cigarette body 1 is placed in the heating body 2 and the electronic cigarette is started, the diameter of the cross section of the heating body 2 is smaller than the diameter of the cigarette body 1, and the inner wall of the heating body 2 and the outer wall of the cigarette body 1 are tightly attached. After the cigarette body 1 is heated for a period of time, the cigarette body 1 becomes thinner. At this time, the inner wall of the heating body 2 shrinks and deforms inward and remains tightly attached to the outer wall of the cigarette body 1 again.

[0047] After the cigarette body 1 is heated for a period of time, as the tobacco oil in the cigarette body 1 evaporates, the cigarette body 1 becomes thinner. At this time, the inner wall of the heating body 2 shrinks and deforms inward and remains close to the outer wall of the cigarette body 1 again, so that the heating body 2 can automatically clamp the cigarette body 1 at all times, so that the heat of the heating body 2 can quickly act on the tobacco leaves or tobacco in the cigarette body 1, so that the heat of the heating body 2 can be fully and directly conducted to the cigarette body 1, thereby achieving the purpose of consuming the least electricity and the fastest response speed, reducing battery energy consumption, increasing usage time under the same battery capacity, and improving user satisfaction.

[0048] Specifically, the heating body 2 has a first state and a second state. When in the first state, the inner wall of the heating body 2 is tightly attached to the outer wall of the cigarette body 1. When the heating body 2 is in the second state, a gap is left between the inner wall of the heating body 2 and the outer wall of the cigarette body 1. When the cigarette body 1 needs to be inserted, the heating body 2 is placed in the second state. At this time, the cigarette body 1 is conveniently inserted into the heating body 2. After the cigarette body 1 is inserted, the heating body 2 is adjusted to the first state under the action of elastic force. At this time, the inner wall of the heating body 2 and the outer wall of the cigarette body 1 are tightly attached, so that the heat of the heating body 2 can quickly act on the tobacco leaves or tobacco shreds of the cigarette body 1, so that the heat of the heating body 2 can be fully and directly conducted to the cigarette body 1, thereby achieving the purpose of consuming the least electricity and the fastest response speed, reducing battery energy consumption.

[0049] As a specific embodiment, in order to enable the heating body 2 to switch between the first state and the second state, the high-efficiency heating without burning electronic cigarette also includes a driving member 3. The driving member 3 drives the inner wall of the heating body 2 to deform in the direction of approaching or away from the cigarette body 1, so that the heating body 2 is converted between the first state and the second state, thereby clamping the cigarette body 1, thereby reducing energy consumption. At the same time, when not in use, a gap is left between the heating body 2 and the cigarette body 1, which is convenient for switching between inserting or removing the cigarette body 1, thereby making the electronic cigarette more convenient to use. When the cigarette body 1 needs to be clamped and heated, or when the cigarette body 1 needs to be inserted or removed, switching can be achieved directly through the driving member 3.

[0050] The heating body 2 includes a connecting section 21 and a plurality of abutting sections 22. The abutting section 22 is annularly arranged on the side of the connecting section 21 facing the cigarette body 1 and one end is connected to the connecting section 21. When the cigarette body 1 is inserted into the heating body 2, the cigarette body 1 is located between the plurality of abutting sections 22. The plurality of abutting sections 22 are open on the side facing away from the connecting section 21, that is, the abutting section 22 is tilted from the end connected to the connecting section 21 away from the cigarette body 1, so that the plurality of abutting sections 22 are open. In the initial state, the cylinder formed by the abutting sections 22 The diameter of the cross section of the shaped structure is larger than the diameter of the cigarette body 1, so the heating body 2 is initially in the second state at this time, which is convenient for inserting and removing the cigarette body 1. In order to enable the abutting section 22 to continue to be in close contact with the cigarette body 1 after the cigarette body 1 is inserted, a pushing member 6 is provided at the abutting section 22. The pushing member 6 drives the abutting section 22 to deform toward the cigarette body 1 until the abutting section 22 and the outer wall of the cigarette body 1 are in close contact, and the heating body 2 is in the first state. When the cigarette body 1 becomes thinner, the pushing member 6 continues to push the abutting section 22, so that the abutting section 22 is in close contact with the outer wall of the cigarette body 1 again.

[0051] The pushing member 6 can be used to convert the heating body 2 from the initial state to the first state, and can continuously push the abutting section 22, so that after the cigarette body 1 becomes thinner, the abutting section 22 and the cigarette body 1 can still be pressed tightly together, so that the heat of the heating body 2 can be fully and directly conducted to the cigarette body 1, reducing battery energy consumption.

[0052] Specifically, the pushing member 6 includes a pressure ring 61 and an elastic member 62 which are sleeved on the heating body 2. The elastic member 62 is configured as a compression spring which is coaxially arranged with the heating body 2. The diameter of the pressure ring 61 is smaller than the cross-sectional diameter of the cylindrical structure formed by the abutting section 22 pressing against the cigarette body 1 in the initial state, and the elastic member 62 is arranged on the side of the pressure ring 61 facing the connecting section 21. The elastic force of the elastic member 62 in the compressed state drives the pressure ring 61 to move away from the connecting section 21, and the pressure ring 61 drives the multiple abutting sections 22 to deform toward the cigarette body 1 until the abutting sections 22 and the outer wall of the cigarette body 1 are pressed tightly. The heating body 2 is in the first state. When the cigarette body 1 becomes thinner, a gap appears between the cigarette body 1 and the abutting section 22. At this time, the elastic member 62 The pressing ring 61 is pushed to move away from the connecting section 21 under the action of the elastic force, so that the pressing ring 61 drives multiple abutting sections 22 to deform toward the cigarette body 1 until the abutting sections 22 are again pressed against the outer wall of the cigarette body 1, so that during the heating process of the cigarette body 1, the abutting sections 22 and the cigarette body 1 are always kept in close contact. The specific structure of the pushing member 6 is not limited in this embodiment. It can be set as a pressing ring 61 and an elastic member 62, or it can be set as an elastic member 62 that pushes the abutting section 22 in the horizontal direction. The elastic member 62 directly pushes the abutting section 22 toward the cigarette body 1 until it is pressed against the cigarette body 1, or other structural methods can be used as long as the abutting section 22 can be pushed so that the abutting section 22 can continue to be pressed against the outer wall of the cigarette body 1.

[0053] At this time, the abutment section 22 is deformed inward by driving the pressure ring 61 through the elastic member 62, rather than being deformed inward directly by the elasticity of the abutment section 22 itself. The control part is transferred to the elastic member 62. When using cigarette bodies 1 of different sizes, only the elastic member 62 and the pressure ring 61 need to be replaced to adapt to the larger or smaller deformation of the abutment section 22, without replacing the heating body 2. Since the replacement of the heating body 2 is cumbersome and inconvenient, and the heating body 2 is more expensive, the use of the elastic member 62 and the pressure ring 61 can make it more convenient to use and save costs.

[0054] A cylindrical bracket 7 is provided at the elastic member 62 . The bracket 7 is cylindrical with one end open. The bracket 7 is sleeved on the heating body 2 and a space is left between the bracket 7 and the heating body 2 to accommodate the elastic member 62 .

[0055] A guide bar 11 is provided on the side of the bracket 7 facing the pressure ring 61. The guide bar 11 extends along the moving direction of the pressure ring 61. A guide hole 12 corresponding to the guide bar 11 is opened on the pressure ring 61. The guide bar 11 extends into the guide hole 12 and slides with the guide hole 12 to guide the pressure ring 61 so that the pressure ring 61 can only slide along the length direction of the heating body 2.

[0056] In order to facilitate the installation of the heating body 2 and the bracket 7, the electronic cigarette also includes a coaxially arranged upper shell 4 and a lower shell 5. The heating body 2 is arranged on the side of the lower shell 5 facing the upper shell 4. The upper shell 4 is arranged to be a hollow cylinder with openings at both ends. The upper shell 4 is sleeved on the heating body 2 and connected to the lower shell 5. The cigarette body 1 extends into the heating body 2 through the opening of the upper shell 4. The end of the bracket 7 facing away from the pressure ring 61 is fixed on the side of the lower shell 5 facing the upper shell 4.

[0057] In order to enable the heating body 2 to be converted from the first state to the second state, the upper shell 4 is rotatably connected to the lower shell 5 with the axis of the lower shell 5 as the rotation axis. The driving member 3 includes an inclined slope 31 arranged on the pressure ring 61. The slope 31 extends along the rotation path direction of the upper shell 4. A pressure block 32 is arranged in the upper shell 4. When the upper shell 4 is rotated and connected to the lower shell 5, the pressure block 32 and the slope 31 conflict; when the upper shell 4 rotates, the pressure block 32 slides on the slope 31 along the length direction of the slope 31, pushing the pressure ring 61 to move toward the connecting section 21, so that the heating body 2 switches from the first state to the second state, facilitating the insertion and removal of the cigarette body 1.

[0058] When the upper shell 4 is mounted on the lower shell 5 , the rotating block 10 is retracted so that the rotating block 10 does not affect the docking of the upper shell 4 and the lower shell 5 . When the upper shell 4 is mounted on the lower shell 5 , the rotating block 10 is retracted so that the rotating block 10 does not affect the docking of the upper shell 4 and the lower shell 5 . When the upper shell 4 and the lower shell 5 are docked in place, the rotating block 10 is located at the rotating groove 9 . Under the action of the spring, the rotating block 10 moves toward the rotating groove 9 until the rotating block 10 extends into the rotating groove 9 . At this time, the rotating block 10 returns to its original shape under the action of the spring and fits the inner wall of the rotating groove 9 , and can slide along the length direction of the rotating groove 9 , so that the upper shell 4 rotates on the lower shell 5 with its axis as the rotating axis.

[0059] Example 2

[0060] Reference Figures 8-12 As shown, the difference between this embodiment and embodiment 1 is that the heating body 2 in this embodiment is configured as an open circular tube 23, and a slit 24 is provided on the side wall of the circular tube 23. The slit 24 is arranged along the length direction of the circular tube 23 and passes through both ends of the circular tube 23; in the initial state, the diameter of the circular tube 23 is smaller than the diameter of the cigarette body 1. When the cigarette body 1 is inserted into the circular tube 23, the cigarette body 1 and the inner wall of the circular tube 23 are pressed tightly. After the cigarette body 1 has been used for a period of time, the cigarette body 1 becomes thinner, and the circular tube 23 will be deformed toward the cigarette body 1 under the action of its own rebound force until it is pressed tightly against the outer wall of the cigarette body 1 again, so that the heat of the heating body 2 can be fully and directly conducted to the cigarette body 1, thereby achieving the purpose of consuming the least electricity and the fastest reaction speed, reducing battery energy consumption, increasing the usage time under the same battery capacity, and improving user satisfaction.

[0061] When in the first state, the diameter of the circular tube 23 is smaller than the diameter of the cigarette body 1. Therefore, when the cigarette body 1 is inserted into the circular tube 23, the circular tube 23 will curl inward under the action of its own resilience, so that the inner wall of the circular tube 23 and the outer wall of the cigarette body 1 are pressed tightly against each other. When in the second state, the gap 24 of the circular tube 23 is opened, and a gap is left between the cigarette body 1 and the inner wall of the circular tube 23. The switching of the circular tube 23 between the first state and the second state can be achieved by the driving member 3.

[0062] In this embodiment, the driving member 3 includes a sliding block 33 that slides along the length direction of the heating body 2. A first pushing block 34 is provided on the wall of the circular tube 23 on both sides of the gap 24. The first pushing block 34 extends along the length direction of the heating body. The opposite side walls of the first pushing block 34 are inclined and the inclination directions are opposite. A second pushing block 35 corresponding to the first pushing block 34 is provided on the sliding block 33. The two second pushing blocks 35 and the two first pushing blocks 34 are arranged in a one-to-one correspondence. The second pushing block 35 is located at the first pushing block 34 and conflicts with the inclined side wall of the first pushing block 34. The second pushing block 35 slides along the length direction of the first pushing block 34.

[0063] When the sliding block 33 is pushed to slide on the heating body 2, the second pushing block 35 slides along the length direction of the first pushing block 34. Since the contact surface of the first pushing block 34 is set to an inclined surface, when the sliding block 33 slides along the length direction of the heating body 2, the second pushing block 35 continues to conflict with the inclined surface of the first pushing block 34, so that the second pushing block 35 can push the two first pushing blocks 34 to move away from each other, and the gap 24 of the circular tube 23 becomes larger, so that the heating body 2 switches from the first state to the second state. When the sliding block 33 slides in the opposite direction, the first pushing block 34 is no longer restricted by the second pushing block 35. Under the action of the elastic force of the circular tube 23 itself, it curls inward, so that the gap of the circular tube becomes smaller, and the two first pushing blocks move towards each other, switching the heating body 2 from the second state to the first state. Two groups of the first pushing block 34 and the second pushing block 35 can be provided, and the two groups are arranged along the length direction of the circular tube 23.

[0064] A switch key 8 is slidably provided on the upper shell 4 , and a linkage block is provided on the side of the switch key 8 facing the slider. The linkage block is inserted into the sliding block 33 . When the switch key 8 slides, it can drive the sliding block 33 to slide along the length direction of the heating body 2 .

[0065] After the cigarette body 1 is heated for a period of time, as the tobacco oil in the cigarette body 1 evaporates, the cigarette body 1 becomes thinner. At this time, the inner wall of the heating body 2 shrinks and deforms inward and again fits tightly against the outer wall of the cigarette body 1, so that the heating body 2 can automatically clamp the cigarette body 1 at all times, so that the heat of the heating body 2 can quickly act on the tobacco leaves or tobacco in the cigarette body 1, so that the heat of the heating body 2 can be fully and directly conducted to the cigarette body 1, thereby achieving the purpose of consuming the least electricity and the fastest response speed, reducing battery energy consumption, increasing usage time with the same battery capacity, and improving user satisfaction.

[0066] Specifically, the heating body 2 has a first state and a second state. When in the first state, the inner wall of the heating body 2 is tightly attached to the outer wall of the cigarette body 1. When the heating body 2 is in the second state, a gap is left between the inner wall of the heating body 2 and the outer wall of the cigarette body 1, which is convenient for inserting the cigarette body 2 into the heating body 2. By sliding the switch key 8, the sliding block 33 is driven to move up and down. At this time, the sliding block 33 releases the force to push the two first push blocks 34, and the round tube 23 curls inward under the action of its own rebound force. The heating body 2 is in the second state. At this time, the cigarette body 1 is convenient to extend into the interior of the heating body 2 and insert After the cigarette body 1 is inserted, the sliding switch key 8 is sliding to drive the sliding block 33 to move up and down. At this time, the sliding block 33 releases the pushing force on the two first pushing blocks 34, and the round tube 23 curls inward under the action of its own resilience, so that the heating body 2 is adjusted from the second state to the first state. At this time, the inner wall of the heating body 2 and the outer wall of the cigarette body 1 are tightly attached, so that the heat of the heating body 2 can quickly act on the tobacco leaves or tobacco shreds of the cigarette body 1, so that the heat of the heating body 2 can be fully and directly conducted to the cigarette body 1, thereby achieving the purpose of consuming the least electricity and the fastest response speed, reducing battery energy consumption.
