Description

Technical Field

[0001] This application relates to the field of smoking device technology, and in particular to a smoking device. Background Technology

[0002] Currently, when the heating element inside a smoking device is heated, it is prone to producing impurities. These impurities cannot be quickly expelled from the device, causing them to accumulate inside. As the amount of impurities increases, the air intake channel inside the device is easily blocked, leading to increased suction resistance and even making it impossible to continue smoking. Utility Model Content

[0003] Based on this, this application provides a smoking device to enhance the smoking experience for users.

[0004] This application provides a smoking device, which includes:

[0005] The main body has a heating chamber and an air intake chamber that are interconnected, and an air intake channel is provided on the side wall of the air intake chamber; and

[0006] Heating components are located inside the heating chamber;

[0007] The air intake channel includes a first channel segment and a second channel segment. The first channel segment extends along the outside of the body in a direction pointing towards the central axis of the body, and the first channel segment connects the outside of the body and the second channel segment. The second channel segment has a first end and a second end that are arranged opposite to each other along the extension direction of the second channel segment, and the second end is connected to one end of the first channel segment. Along the direction from the heating chamber to the air intake chamber, the first end is located downstream of the second end.

[0008] In some embodiments of this application, the side wall of the main body is provided with a mounting hole, which communicates with the air intake chamber;

[0009] The smoking device also includes a detachable component, which is detachably mounted on the main body and has an air intake channel.

[0010] In some embodiments of this application, the detachable component is configured as a valve.

[0011] In some embodiments of this application, the extension direction of the first channel segment is perpendicular to the extension direction of the second channel segment.

[0012] In some embodiments of this application, the extension direction of the second channel segment is parallel to the extension direction of the central axis of the body.

[0013] In some embodiments of this application, the extension length of the first channel segment is greater than the extension length of the second channel segment.

[0014] In some embodiments of this application, a plane perpendicular to the central axis of the body is defined as a first plane, and the orthographic projection of the heating component on the first plane and the orthographic projection of the air intake channel on the first plane do not overlap with each other.

[0015] In some embodiments of this application, the smoking device also includes a base, an air inlet chamber formed between the base and the heating assembly, and the base is located downstream of the air inlet channel along the direction from the heating chamber to the air inlet chamber, and the base is disposed close to the air inlet channel.

[0016] In some embodiments of this application, the shape of the radial cross section of the first channel segment is the same as the shape of the radial cross section of the second channel segment.

[0017] In some embodiments of this application, the radial cross-section of the first channel segment and the radial cross-section of the second channel segment are both circular.

[0018] The aforementioned smoking device includes a main body and a heating assembly. The main body has a heating chamber and an air intake chamber that are interconnected, and the heating assembly is disposed within the air intake chamber. When the user smokes, external air enters the air intake chamber through the air intake channel, and then enters the heating chamber, which is connected to the air intake chamber. The heating assembly heats the air to provide heated air for the subsequent smoking process. The air intake channel includes a first channel segment and a second channel segment. The first channel segment extends along the exterior of the main body in a direction pointing towards the central axis of the main body, and the first channel segment connects the exterior of the main body and the second channel segment, allowing air to enter the second channel segment from the outside and then into the air intake chamber. The second channel segment has a first end and a second end that are oppositely disposed along its extension direction. The second end is connected to one end of the first channel segment; along the direction from the heating chamber to the air intake chamber, the first end is located downstream of the second end. In this way, impurities are less likely to fall into the second channel section, reducing the risk of impurities falling into the air intake channel and thus reducing the risk of air intake channel blockage. Furthermore, air only needs to pass through the first and second channel sections to enter the air intake chamber, simplifying the path of air entering the air intake chamber from the outside. External air can flow more smoothly from the first channel section into the second channel section, improving the user's smoking experience. Attached Figure Description

[0032] Please refer to Figure 1 and Figure 3 , Figure 1 This paper shows a three-dimensional structural schematic diagram of the smoking device 100 in some embodiments of this application. Figure 2 It shows Figure 1 The front view of the smoking device 100. Figure 3 It shows Figure 2 A cut-off view of the cross-section at point aa. Figure 3 The black arrows in the diagram indicate the direction of airflow after entering the smoking device 100. The smoking device 100 provided in this application includes a body 1 and a heating component 2.

[0033] The main body 1 is the basis of the smoking device 100, and can be set with any structure and shape that is convenient to hold and use, such as cylindrical or square. This application does not limit it.

[0034] The heating component 2 is a key heating component in the smoking device 100. It is located in the heating chamber B. The main function of the heating component 2 is to provide heat to the cigarette to complete the heating and baking process of the cigarette, thereby releasing smoke that can be inhaled by the user.

[0035] The specific heating component 2 may include a heat-conducting element and a heating element embedded within the heat-conducting element. For example, the heat-conducting element may be graphite, and the heating element may be a resistance wire; however, this is not limited to any particular type. Graphite can quickly conduct heat from the resistance wire to the cigarette, improving the uniformity and efficiency of heating, helping the cigarette to be heated evenly during the heating process and releasing higher-quality smoke. Graphite has good mechanical strength and wear resistance, maintaining structural integrity during repeated heating and cooling, reducing the risk of damage due to thermal expansion and contraction. The resistance wire can rapidly generate heat after being energized, providing stable heat output, enabling the heating component 2 to quickly respond to user operations and improving the user experience. The smoking device 100 proposed in this application also includes a power supply, which controls the on and off of the resistance wire. Specifically, the heat generated by the resistance wire is quickly conducted to the cigarette through graphite. The thermal conductivity of graphite ensures uniform heat distribution, preventing localized overheating or underheating, and improving heating efficiency and the quality of the cigarette's baking process.

[0036] In some embodiments, a vacuum tube is fitted over the heat-conducting component, and the gap between the outer wall of the vacuum tube and the inner wall of the heating chamber B forms an airflow channel. The vacuum tube consists of two concentric glass or metal tubes, and the space between the two tubes is evacuated. By incorporating the vacuum tube, a heat insulation effect can be achieved, reducing heat loss from the heat-conducting component. In the design of the smoking device 100, the vacuum tube can reduce the heat loss of the heating component 2 to the surrounding environment during operation, allowing more heat to be used for heating and baking the cigarette, thus improving the user experience. At the same time, the heat insulation effect can also prevent the outer shell of the smoking device 100 from overheating, improving safety during use.

[0037] An air intake channel A is provided on the side wall of the air intake chamber C, and the air intake channel A includes a first channel segment A1 and a second channel segment A2. The first channel segment A1 extends along the outside of the body 1 in the direction pointing to the central axis of the body 1, and the first channel segment A1 connects the outside of the body 1 and the second channel segment A2.

[0038] Thus, when the smoking device 100 is in use, the smoker inhales, and a negative pressure is generated inside the smoking device 100, allowing air to enter from the outside through the first channel section A1 into the second channel section A2 and then into the air intake chamber C, and then into the heating chamber B. The heating component 2 heats the air to provide heated air for the subsequent baking of the cigarette, so that the smoking device 100 can operate smoothly.

[0039] Continue to refer to Figure 1 and Figure 3 and in conjunction with reference Figure 4 ,Figure 4 It shows Figure 3 A magnified view of a portion at point b. The second channel segment A2 has a first end D1 and a second end D2 arranged opposite to each other along its extension direction. The second end D2 is connected to one end of the first channel segment A1. The first end D1 is located downstream of the second end D2 along the direction from the heating chamber B to the air intake chamber C.

[0040] In this way, impurities are less likely to fall into the second channel section A2, reducing the risk of impurities falling into the air intake channel A, and thus reducing the risk of blockage in the air intake channel A. Furthermore, air only needs to pass through the first channel section A1 and the second channel section A2 to enter the air intake chamber C, simplifying the path of air entering the air intake chamber C from the outside. External air can flow more smoothly from the first channel section A1 into the second channel section A2, improving the user's smoking experience.

[0041] The air intake channel A of this application includes a first channel segment A1 and a second channel segment A2. Air only needs to pass through two channel segments to reach the air intake chamber C. The path is simple and direct. During the flow of air, it is not easy for the flow rate to fluctuate due to too many channel turns or branches. This makes the amount of air entering the heating chamber B more stable, which is conducive to the heating component 2 to heat the air evenly.

[0042] In some embodiments, the smoking device 100 further includes a cigarette insert and a cigarette stick. The cigarette stick is inserted into the cigarette insert, allowing it to be securely placed within the smoking device 100, preventing displacement during heating and ensuring uniform and efficient heating. Simultaneously, the design of the cigarette insert facilitates easy insertion and removal of the cigarette by the user, enhancing usability.

[0043] In some embodiments, the heat-conducting element described above has multiple through holes, allowing air to enter the heating chamber B from the air inlet chamber C and come into contact with the cigarette. The number and shape of the through holes are not limited herein.

[0044] In some embodiments, the smoking device 100 further includes a cigarette holder for inserting a cigarette. Specifically, the cigarette is inserted into the cigarette holder, and the heating element heats the heat-conducting element. When the heat-conducting element heats up, it heats the air around the heat-conducting element to form hot air. When inhaling, the hot air rises through the through hole to bake the cigarette in the cigarette holder, thereby generating smoke.

[0045] In some embodiments of this application, reference continues to be made to... Figures 1 to 4 The side wall of the main body 1 is provided with an installation hole, which is connected to the air inlet chamber C. The smoking device 100 also includes a detachable part 3, which is detachably disposed on the main body 1 and is provided with an air inlet channel A.

[0046] It is understandable that when the smoking device 100 is in use, the heating component 2 will generate impurities, such as carbon ash, after being heated. These impurities will fall from the heating chamber B into the air intake chamber C for storage. Excessive accumulation of impurities can easily cause blockage of the smoking device 100, thereby reducing its lifespan and affecting the user experience. Therefore, timely cleaning is necessary. This application provides a detachable part 3. When it is necessary to clean the impurities in the smoking device 100, it is only necessary to remove the detachable part 3 from the main body 1. This allows the impurities to flow from the air intake chamber C to the second channel section A2 and then through the first channel section A1 to be poured out to the outside of the smoking device 100. This timely cleaning of impurities that may block the air intake channel A reduces the possibility of blockage in the air intake channel A, allowing the smoking device 100 to operate normally. The detachable connection methods include, but are not limited to, threaded connections and snap-fit ​​connections.

[0047] Specifically, in this application, the air intake channel A includes a first channel section A1 and a second channel section A2. The structures of the first channel section A1 and the second channel section A2 are relatively simple, making them easier to clean. Once impurities enter the air intake channel A, cleaning personnel can more easily clean and maintain both channel sections, ensuring that the air intake channel remains unobstructed.

[0048] In some embodiments of this application, reference continues to be made to... Figures 1 to 4 The detachable part 3 is configured as a valve.

[0049] Thus, during the cigarette heating process, a stable airflow is required to ensure uniform combustion and heating of the cigarette. The valve can adjust the flow rate as needed to improve the consistency of the heating effect. Furthermore, the valve can open and close the air intake channel A. When the user is not smoking, closing the valve can prevent external impurities from entering the smoking device 100, thereby extending the service life of the smoking device 100.

[0050] Specifically, different types of valves can be selected to provide different flow regulation ranges and precisions, depending on the needs of the smoking device 100. For example, a solenoid valve can be used in a smoking device 100 that requires precise control of gas flow and automated operation, while a pneumatic valve can be used in a smoking device 100 that requires a larger gas flow and stable control.

[0051] In some embodiments of this application, reference continues to be made to... Figures 1 to 4 The extension direction of the first channel segment A1 is perpendicular to the extension direction of the second channel segment A2.

[0052] Thus, when air enters the second channel section A2 vertically downwards, the gravitational potential energy of the air increases and the kinetic energy decreases, thereby reducing the air speed and the impact on the intake chamber C and heating component 2, making the air enter the intake chamber C more smoothly.

[0053] During the heating process of the smoking device 100, the heat is mainly concentrated in the heating chamber B and the air intake chamber C. Since the first channel section A1 and the second channel section A2 are perpendicular, the heat is hindered to a certain extent during the transfer of heat to the external environment along the channel, thereby reducing the heat loss to the external environment and improving the thermal efficiency inside the smoking device 100.

[0054] Furthermore, during the use of the smoking device 100, after the smoke enters the second channel section A2, since the extension direction of the second channel section A2 is perpendicular to the extension direction of the first channel section A1, the backflow of smoke needs to overcome the resistance caused by the change in direction, thereby effectively reducing the possibility of backflow of smoke and enabling the user to inhale relatively pure smoke.

[0055] In some embodiments of this application, reference continues to be made to... Figures 1 to 4 The extension direction of the second channel segment A2 is parallel to the extension direction of the central axis of the body 1.

[0056] This ensures a clear and stable path for air as it flows downwards along the second channel segment A2. Specifically, since the extension direction of the second channel segment A2 is parallel to the extension direction of the central axis of the main body 1, the air experiences uniform force and a relatively stable velocity distribution within the second channel segment A2. This reduces turbulence and velocity fluctuations caused by the tilting or bending of the channel. Consequently, when the air needs to overcome gravity to enter the heating chamber B, the air already has a uniform distribution and stable flow velocity within the air intake chamber C, resulting in even smaller velocity fluctuations when overcoming gravity.

[0057] In some embodiments of this application, reference continues to be made to... Figures 1 to 4 The extension length of the first channel segment A1 is greater than the extension length of the second channel segment A2.

[0058] The longer first channel section A1 provides a longer buffer zone before the air enters the second channel section A2. This results in a more uniform air velocity as it enters the second channel section A2, reducing turbulence and eddies caused by velocity variations, thus making the smoking process smoother for the user. Furthermore, the longer first channel section A1 provides a longer path, allowing impurities more opportunities to deposit on the walls of the first channel section A1 before entering the second channel section A2. This reduces the risk of impurities entering the second channel section A2 and the air intake chamber C, lowering the likelihood of the smoking device 100 becoming clogged.

[0059] Reference continues to be made to some embodiments of this application. Figures 1 to 4 The plane perpendicular to the central axis of the body 1 is defined as the first plane. The orthographic projection of the heating component 2 on the first plane and the orthographic projection of the air intake channel A on the first plane do not overlap with each other.

[0060] The first plane can be understood as a virtual cross-section, which cuts a cross section along the direction perpendicular to the central axis of the body 1 of the smoking device 100.

[0061] During the use of the smoking device 100, impurities such as carbon ash will fall from the heating chamber B to the air intake chamber C. In order to reduce the risk of impurities entering the second channel section A2 during the falling process, this application arranges the air intake channel A and the heating component 2 in a direction perpendicular to the central axis, so that the falling impurities are not easily caught by the second channel section A2, thereby reducing the risk of impurities clogging the air intake channel A and improving the service life of the smoking device 100.

[0062] In some embodiments of this application, reference continues to be made to... Figures 1 to 4 and in conjunction with reference Figure 5 , Figure 5 It shows Figure 3 Partial truncated view. The smoking device 100 also includes a base 4, an air inlet chamber C formed between the base 4 and the heating component 2, in the direction from the heating chamber B to the air inlet chamber C, the base 4 is located downstream of the air inlet channel A, and the base 4 is positioned close to the air inlet channel A.

[0063] Thus, by providing a base 4, the base 4 can collect the impurities generated after the heating component 2 is heated. Since the base 4 is located in the path of the falling impurities, most of the impurities will be collected by the base 4, reducing the risk of impurities scattering everywhere, thereby reducing contamination of other internal components of the smoking device 100 and keeping the inside of the smoking device 100 clean.

[0064] When cleaning impurities is required, the base 4 is positioned to facilitate the removal of impurities from the base 4 towards the air intake channel A. Because the base 4 is close to the air intake channel A, cleaning can be done directly from the base 4, removing impurities along the direction of the air intake channel A without needing to go deep into the smoking device 100 for complicated operations, thus reducing the difficulty and time cost of cleaning.

[0065] In some embodiments of this application, reference continues to be made to... Figures 1 to 5 The radial cross-section of the first channel segment A1 has the same shape as the radial cross-section of the second channel segment A2.

[0066] The radial section refers to the shape obtained by a plane that passes through and is perpendicular to the central axis of the object.

[0067] Since the radial cross-section of the first channel section A1 has the same shape as the radial cross-section of the second channel section A2, the airflow does not need to adjust its direction or speed when passing through the air intake channel A, thereby reducing airflow disturbance and turbulence and effectively improving the performance of the smoking device 100.

[0068] In some embodiments of this application, reference continues to be made to... Figures 1 to 5The radial cross-sections of the first channel segment A1 and the second channel segment A2 are both circular.

[0069] Thus, the circular cross-section provides the smoothest airflow path. Compared to other shapes, such as squares or rectangles, the circular cross-section has no sharp corners or edges, which significantly reduces airflow resistance within the channel, allowing air to flow more smoothly from the first channel section A1 into the second channel section A2, and finally to the air intake chamber C. Furthermore, the circular cross-section can evenly distribute stress under pressure. In practical use, the air intake channel A of the smoking device 100 may be subjected to certain pressures, such as the negative pressure generated during smoking or the expansion pressure of air during heating. The circular cross-section can evenly distribute these pressures across the entire channel wall, reducing stress concentration points and thus lowering the risk of channel deformation or damage due to pressure.

[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
