Description

Technical Field

[0001] The present invention relates to the technical field of smoking articles, and in particular to a low-temperature smoking article. Background Art

[0002] The central heating low-temperature smoking device heats the cigarette by directly inserting the heating element into the cigarette. After the cigarette is heated, the smoking material and the heating element are bonded together. Pulling out the cigarette directly will cause the smoking material to separate from the cigarette and remain in the heating chamber of the device, which is extremely inconvenient to clean. Currently, most central heating devices on the market use an extractor structure. After the cigarette is smoked, the extractor is manually pushed, and then the cigarette is pulled out. Although this method can separate the smoking material from the heating element, because there is a heating element in the heating chamber, the residual smoke oil and smoke material debris in the heating chamber after long-term use are still not easy to clean.

[0061] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] The embodiment of the present application provides a low-temperature smoking device, which is used to solve the problem that the heating chamber of the existing smoking device is inconvenient to clean.

[0063] Example 1

[0064] See also Figure 1 and Figure 2 The low-temperature smoking device provided in Example 1 of the present application includes a shell 1, a heating element 2, a sliding member 3 and a first locking mechanism 4. A heating chamber 5 for accommodating cigarettes is formed inside the shell 1. The heating element 2 is arranged in the heating chamber 5 to heat the cigarettes. The sliding member 3 is slidably arranged in a receiving groove 6 on the shell 1, and can slide in the receiving groove 6 relative to the shell 1 between a first position and a second position. The heating element 2 is installed on the sliding member 3 and moves synchronously with the sliding member 3. The first locking mechanism 4 is arranged between the receiving groove 6 and the sliding member 3, and is used to lock the sliding member 3 in the first position and can be unlocked. When the first locking mechanism 4 locks the sliding member 3 in the first position, the heating element 2 is inserted into the heating chamber 5. After the first locking mechanism 4 is unlocked and the sliding member 3 slides to the second position, the heating element 2 withdraws from the heating chamber 5.

[0065] In the embodiment of the present application, when the heating chamber 5 needs to be cleaned, the heating element 2 can be withdrawn from the heating chamber 5 by sliding the slider 3, and the heating chamber 5 can be cleaned. During cleaning, the heating chamber 5 is easy to clean because there is no obstruction of the heating element 2 in the heating chamber 5. In addition, when the heating element 2 is inserted into the heating chamber 5, the slider 3 will be locked by the first locking mechanism 4, which can prevent the slider 3 from moving back due to excessive resistance when the cigarette is inserted.

[0066] In some possible implementation schemes, the heating chamber 5 has a first end and a second end opposite to each other, wherein the first end is used for inserting the cigarette, and the second end is a closed end, and a through hole (not shown in the figure) suitable for the heating element 2 to pass through is provided on the closed end, and the heating element 2 is driven by the sliding member 3 to pass through the through hole and enter the heating chamber 5. When in use, the cigarette is inserted into the heating chamber 5 from the first end of the heating chamber 5, and the corresponding heating element 2 is inserted into the cigarette, and the smoke is sucked away by the user from the end of the cigarette away from the heating element 2. When the cigarette needs to be withdrawn, the heating element 2 is driven to move relative to the heating chamber 5 by sliding the sliding member 3, and the cigarette is in a stationary state because it cannot overcome the static friction between the cigarette and the heating chamber 5, so that the heating element 2 withdraws from the cigarette.

[0067] In the embodiment of the present application, the outer shell 1 is used to accommodate other devices in the low-temperature smoking device. A cigarette insertion port directly connected to the first end of the heating chamber 5 is provided on the top of the outer shell 1. The cigarette enters the heating chamber 5 from the cigarette insertion port. The outer shell 1 can be surrounded by a top plate 101, a shell body 102 and a bottom plate 103.

[0068] Specifically, a control component is provided in the housing 1, and the control component is used to control the temperature change of the heating element 2 so that it can heat the smoking material, and can include a power supply 7, a circuit board 8 and a button 9. The heating element 2 can be connected to the circuit board 8 through a wire to realize circuit conduction. The button 9 is generally provided on the outer wall of the housing. The power supply 7, the circuit board 8 and the button 9 are electrically connected to the heating element 2 to form a heating control circuit for the heating element 2. As for the specific structure of the heating control circuit for the heating element 2, they are all conventional designs in the electrical field and are not described here. The power supply 7 can be an electric energy body such as a nickel-hydrogen battery, a lithium-ion battery or a fuel cell.

[0069] In the embodiment of the present application, the heating element 2 can be withdrawn from the cigarette, so that the carbonized tobacco material adhered to the heating element 2 during the heating process moves with the cigarette and separates from the heating element 2, and less residue is left on the heating element 2. In addition, during the withdrawal of the heating element 2, the side wall of the through hole can scrape the tobacco shreds remaining on the heating element 2, which can further reduce the residue on the heating element 2, and the tobacco shreds or tobacco oil residues that fall from the cigarette are all contained in the heating chamber 5, without contaminating other parts of the smoking device, and only the heating chamber 5 needs to be cleaned.

[0070] It is understandable that the cigarette can adopt a two-section structure, consisting of a filter section and a tobacco section containing a smoking material. The low-temperature cigarette of the above structure can be produced using an existing ordinary cigarette production line without the need to modify the existing production line.

[0071] It can be imagined that when the cigarette is inserted into the heating chamber 5, when the filter section of the cigarette is at least partially exposed from the outer shell 1, the user can directly hold the filter and inhale, without having to set up a suction component separately in the smoking device. The cost of the smoking device is reduced, and the filter can be replaced along with the cigarette after the cigarette is smoked. Different smokers can use the same smoking device for smoking, and the smoking device has strong adaptability.

[0072] Specifically, in order to facilitate insertion into the cigarette, the heating element 2 can be a heating rod or a heating sheet, and a spike portion can be provided at the front end of the heating rod or the heating sheet. Of course, the heating element 2 of other shapes can also be used.

[0073] As for the entire airway structure of the low-temperature smoking device, it is not the focus of improvement of the present application. For example, existing conventional air intake structures such as side air intake or bottom air intake can be adopted. When side air intake is adopted, an axial air flow groove can be set on the side of the heating chamber 5. When bottom air intake is adopted, an air intake hole that passes through the outer shell 1 can be directly set at the second end of the heating chamber 5.

[0074] See also Figure 1-Figure 4 It should be explained that the first locking mechanism 4 includes a first positioning pin 401 and a first elastic reset member 402. The first positioning pin 401 is slidably installed in the first pin hole 10 on the side of the sliding member 3. The first elastic reset member 402 is connected between the first positioning pin 401 and the first pin hole 10. The accommodating groove 6 is provided with a first positioning hole 11 that matches the first positioning pin 401. The first positioning pin 401 is provided with a first unlocking member 12 that drives the first positioning pin 401 to withdraw from the first positioning hole 11. Among them, the first elastic reset member 402 can be a spring or a spring.

[0075] In the embodiment of the present application, the sliding member 3 is limited by an elastic positioning pin. When the sliding member 3 moves to the first position, the first positioning pin 401 cooperates with the first positioning hole 11 to fix the position of the sliding member 3, and the first elastic reset member 402 applies an axial force pointing to the first positioning hole 11 to the first positioning pin 401. When unlocking is required, it is only necessary to move the first unlocking member 12 to withdraw the first positioning pin 401 from the first positioning hole 11. Of course, the first locking mechanism 4 can also adopt other existing locking mechanisms, which will not be described here.

[0076] See also Figure 1-Figure 4In some other possible implementation schemes, a sliding cover 13 is slidably installed on the outer wall of the shell 1 through a groove body to drive the sliding member 3 to slide in the accommodating groove 6. The sliding cover 13 is limited by the groove body to slide close to the shell 1, and the extension direction of the groove body is parallel to the accommodating groove 6. The sliding cover 13 is connected to the sliding member 3 through a pushing block 14. The sliding cover 13 is provided with a pushing groove 15 that is sleeved on the pushing block 14. The pushing groove 15 has a first end and a second end that are opposite and closed. The pushing groove 15 also has a first guide inclined surface 16 that cooperates with the first unlocking member 12.

[0077] In which, when the sliding cover 13 drives the sliding member 3 to move from the first position to the second position, the pushing block 14 first moves from the first end to the second end of the pushing slide groove 15, and then forces the sliding member 3 to move synchronously with the sliding cover 13; when the pushing block 14 moves from the first end to the second end of the pushing slide groove 15, the first guide slope 16 squeezes the first unlocking member 12 to force the first positioning pin 401 to withdraw from the first positioning hole 11.

[0078] In the process of the sliding cover 13 driving the sliding member 3 to move from the second position to the first position, the pushing block 14 first moves from the second end of the pushing slide groove 15 to the first end, and then forces the sliding member 3 to move synchronously with the sliding cover 13. When the first positioning pin 401 on the sliding member 3 runs to the position of the first positioning hole 11, the first positioning pin 401 is reinserted into the first positioning hole 11 under the action of the elastic reset force provided by the first elastic reset member, locking the sliding block at the first position, and at the same time, the first positioning pin 401 drives the first unlocking member 12 to reset.

[0079] In the embodiment of the present application, the sliding cover 13 can be pushed by hand to move up and down relative to the housing 1. The sliding cover 13 has a pushing slot 15. The sliding member 3 is provided with a pushing block 14 that matches the pushing slot 15. The pushing slot 15 is used to drive the sliding member 3 to move up and down. The pushing slot 15 has a guiding slope, which is used to squeeze the first positioning pin 401 to make the first positioning pin 401 disengage from the first positioning hole 11. The first elastic reset member 402 is used to reset the first positioning hole 11. Among them, "up" refers to the direction of the heating element 2 approaching the heating chamber 5, that is, the first position direction, and "down" refers to the direction of the heating element 2 away from the heating chamber 5, that is, the second position direction.

[0080] In the embodiment of the present application, one action of pushing the sliding cover 13 can realize three actions of sliding member limit release - moving the heating element - automatic limit, which is easy to operate.

[0081] See also Figure 1-Figure 7Specifically, a first axial slide groove 17 is provided on the side of the first pin hole, and the first unlocking member 12 is slidably arranged in the first axial slide groove 17, and one end is fixedly connected to the first positioning pin 401, and the other end extends into the pushing slide groove 15 and cooperates with the first guide inclined surface 16. When the pushing block 14 moves from the first end to the second end of the pushing slide groove 15, the first guide inclined surface 16 squeezes the first unlocking member 12 to force the first unlocking member 12 to slide in the first axial slide groove 17, thereby driving the first positioning pin 401 to move axially in the first pin hole 10 and compressing the first elastic return member 402, so that the first positioning pin 401 withdraws from the first positioning hole 11.

[0082] In actual application, a guide groove 18 is also provided on the inner wall of the accommodating groove 6, and a slide rail matching and inserted into the guide groove 18 is provided on the side of the sliding member 3. The extension direction of the guide groove 18 is parallel to the sliding direction of the sliding member 3. The sliding member 3 is limited to move only along the extension direction of the accommodating groove 6 by the cooperation between the slide rail and the guide groove 18.

[0083] See also Figure 1-Figure 7 In some other possible implementation schemes, the low-temperature smoking device in the embodiment of the present application also includes a second locking mechanism 19 for locking the sliding member 3 in the second position, the second locking mechanism 19 includes a second positioning pin 1901 and a second elastic reset member 1902, a second pin hole 20 is provided on the sliding member 3, and a second positioning hole 21 matching with the second positioning pin 1901 is provided on the accommodating groove 6, the second elastic reset member 1902 is connected between the second positioning pin 1901 and the second pin hole 20, the first positioning pin 401 is slidably installed in the first pin hole 10 on the side of the sliding member 3, the pushing slide groove 15 also has a second guide inclined surface 22, and the second positioning pin 1901 is provided with a second unlocking member 23 matching with the second guide inclined surface 22.

[0084] See also Figure 7-Figure 12 In the embodiment of the present application, when the sliding cover 13 drives the sliding member 3 to move from the first position to the second position, the pushing block 14 first moves from the first end to the second end of the pushing slide groove 15, and then forces the sliding member 3 to move synchronously with the sliding cover 13. When the sliding cover 13 moves to the second position, the second positioning pin 1901 and the second unlocking member are reset under the elastic restoring force of the second elastic reset member, and the second positioning pin 1901 is inserted into the second positioning hole 21 to lock the sliding member at the second position.

[0085] When the sliding cover 13 drives the sliding member 3 to move from the second position to the first position, the pushing block 14 first moves from the second end of the pushing slide slot 15 to the first end, and then forces the sliding member 3 to move synchronously with the sliding cover 13. When the sliding cover 13 moves to the first position, the first positioning pin 401 and the first unlocking member are reset under the elastic restoring force of the first elastic reset member 402, and the first positioning pin 401 is inserted into the first positioning hole 21 to lock the sliding member in the first position. When the pushing block 14 moves from the second end of the pushing slide slot 15 to the first end, the second guiding inclined surface 22 squeezes the second unlocking member 23 to force the second positioning pin 1901 to withdraw from the second positioning hole 21.

[0086] It should be explained that a second axial groove 24 is also provided on the side of the second pin hole 20, and the second unlocking member 23 is slidably set in the second axial groove 24, and one end is fixedly connected to the second positioning pin 1901, and the other end extends into the pushing groove 15, and the extension direction of the second axial groove 24 is parallel to the axis of the second pin hole 20.

[0087] In practical applications, the first pin hole 10 and the second pin hole 20 are arranged back to back, and their axes coincide and are connected. The first locating pin and the second locating pin can be directly connected by an elastic return member, so an elastic return member can be omitted.

[0088] The process of the low-temperature smoking device sliding cover 13 driving the sliding member 3 to move is as follows:

[0089] Figure 1 , Figure 3 and Figure 4 The schematic diagram shown is when the slide cover 13 is in the first position, the first positioning pin 401 cooperates with the first positioning hole 11, so that the slide member 3 is fixed on the housing 1, and the slide member 3 is at the top dead point of the movement stroke. At this time, the cigarette can be inserted into the heating chamber 5 for smoking, because the heating element 2 will be inserted into the smoking material of the cigarette at the same time during the process of inserting the cigarette into the heating chamber 5. This process will cause the heating element 2 to be subjected to downward pressure from the cigarette, and this structure can keep the slide member 3 stable in the current position when the slide cover 13 is not pushed manually.

[0090] When the cigarette is finished being smoked, the sliding cover 13 is pushed downwards. Figure 7 and Figure 8 As shown, the first guide slope 16 of the sliding cover 13 squeezes the first unlocking member 12, forcing the first unlocking member 12 to move in the first axial slot 17, thereby driving the first positioning pin 401 to move in the first pin hole 10, withdrawing the first positioning pin 401 from the first positioning hole 11, and then the pushing block 14 contacts the second end of the pushing slot 15. While the sliding cover 13 continues to move downward, the pushing slot 15 on the sliding cover 13 will drive the sliding member 3 to move downward together.

[0091] like Fig. 9 and Fig.10 As shown, when the slide 3 moves downward to the position where the second positioning pin 1901 is adjacent to the second positioning hole 21, the second positioning pin 1901 is inserted into the second positioning hole 21 under the action of the elastic reset member, so that the slide 3 is fixed on the housing 1, and the slide 3 is at the lower dead point of the movement stroke, and the slide 3 and the slide cover 13 cannot continue to move downward. At this time, the heating element 2 has been separated from the smoking material of the cigarette, and the cigarette can be directly pulled out without worrying about the smoking material being left in the heating chamber 5, and it is also convenient to clean the heating chamber 5.

[0092] Push the slide cover 13 upwards, as shown in FIG. Fig.11 and Fig.12 As shown, the second guide slope 22 of the sliding cover 13 squeezes the second unlocking member 23, forcing the second unlocking member 23 to move in the second axial slide groove 24, thereby driving the second positioning pin 1901 to move in the second pin hole 20, withdrawing the second positioning pin 1901 from the second positioning hole 21, and then the pushing block 14 contacts the first end of the pushing slide groove 15. While the sliding cover 13 continues to move upward, the pushing slide groove 15 on the sliding cover 13 will drive the sliding member 3 to move upward together until the sliding member 3 returns to the initial position.

[0093] In the embodiment of the present application, the sliding member 3 can be locked and fixed in both the first position and the second position, and the movement of the sliding member 3 and the locking and unlocking of the first position and the second position can be achieved simply by sliding the sliding cover 13 back and forth, which is convenient to operate.

[0094] Example 2

[0095] See also Figure 13-Figure 15 Different from Example 1, in the low-temperature smoking device provided in Example 2 of the present application, the second locking mechanism 19 includes a second positioning pin 1901 and a second elastic reset member 1902, and the accommodating groove 6 is provided with a second positioning hole 21 that matches the second positioning pin 1901.

[0096] Specifically, the sliding member 3 is provided with a second pin hole 20 connected to the first pin hole 10, the axis of the first pin hole 10 is parallel to the axis of the second pin hole 20, the second positioning pin 1901 is arranged in the second pin hole 20, and the second elastic reset member 1902 is connected between the first positioning pin 401 and the second positioning pin 1901. When the pushing block moves from the second end of the pushing slide groove to the first end, the first unlocking member slides against the first guide slope 16 under the action of the reset force of the first elastic reset member, and finally drives the second positioning pin to withdraw from the second positioning hole to achieve unlocking.

[0097] The process of the low-temperature smoking device sliding cover driving the sliding member to move in the embodiment of the present application is as follows:

[0098] When the sliding cover 13 is pushed upward, the pushing block moves along the trajectory of the pushing slide groove. At the same time, the first positioning pin, the second elastic reset member and the second positioning pin move in a direction away from the second positioning hole 21 under the reset force of the first elastic reset member, and the first unlocking member 12 resists and slides on the first guide slope 16. As the first positioning pin continues to move away from the second positioning hole 21, the first positioning pin will eventually drive the second positioning pin 1901 to withdraw from the second positioning hole 21 to achieve unlocking; when the sliding cover 13 continues to be pushed, the pushing slide groove on the sliding cover 13 will drive the sliding member to move upward together until the first positioning pin is reinserted into the first positioning hole under the reset force of the first elastic reset member. Fig.15 and 16 shown.

[0099] When the sliding cover 13 moves downward, the first guiding inclined surface 16 squeezes the first unlocking member 12 to force the first positioning pin 401 to withdraw from the first positioning hole 11 and compress the first elastic reset member, and then continues to squeeze the first unlocking member 12 to force the first positioning pin 401 to retreat axially along the first pin hole 10 to compress the first elastic reset member and the second elastic reset member. When the sliding cover 13 continues to move downward so that the top of the pushing slide groove contacts the pushing block, the slider will drive the sliding member to move downward together; when the sliding member is driven to the second position by the sliding cover, the second positioning pin 1901 is inserted into the second positioning hole 21 under the action of the second elastic reset member, so that the sliding member 3 is fixed on the housing. At this time, the sliding member 3 is at the lower dead point of the movement stroke, as shown in FIG. Fig.17 and 18 shown.

[0100] Compared with the first embodiment, the unlocking of the first locking mechanism 4 and the second locking mechanism 19 in this embodiment is controlled by the first push rod and the first guide inclined surface 16 that conflicts with the first push rod, and the structure is simpler.

[0101] The above embodiments are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
