Description

Technical Field

[0001] This utility model relates to the technical field of smoking devices, and in particular to a portable smoking device with retractable control. Background Technology

[0002] Traditional ashtrays, as a basic tool for collecting cigarette ash, are typically designed in a fixed manner, making them inconvenient to carry and requiring precise aiming of the cigarette at the ashtray. Furthermore, these ashtrays often lack effective sealing mechanisms, allowing ash to easily scatter due to external airflow, especially in indoor and vehicle environments. This not only causes environmental pollution but can also pose safety hazards, such as fires.

[0003] To address these issues, existing technologies have proposed several solutions. For example, a portable multi-functional smoking device recently filed by the applicant uses a rotating top cover to accommodate upper insertion holes of different sizes and a fixed lower insertion hole, thus adapting to cigarettes of different diameters; a ventilation window is provided through the side wall of the grip tube to allow smoke to escape. These solutions improve ease of use and reduce the risk of lost accessories, but they still have some limitations:

[0004] 1. Fixed ventilation windows do not restrict airflow, making it difficult to extinguish cigarettes easily;

[0005] 2. Fixed ventilation windows cannot prevent ash from spilling when smoking devices are tilted or in other moving scenarios, which is not conducive to maintaining hygiene and cleanliness;

[0006] 3. Fixed ventilation windows increase the longitudinal dimensions of smoking devices, limiting their miniaturization.

[0007] In view of this, the inventor has specifically designed a portable smoking device with retractable control, which leads to this invention. Utility Model Content

[0008] To solve the above problems, the technical solution of this utility model is as follows:

[0009] A retractable and controllable portable smoking device, comprising:

[0010] The grip tube has an inner cavity with an opening at the top.

[0011] The lifting cylinder is slidably inserted into the inner side of the upper opening of the gripping cylinder, or slidably sleeved on the outer side of the upper end of the gripping cylinder;

[0012] The top cover, located at the upper end of the lifting cylinder, has a cigarette insertion hole that allows a cigarette to be inserted into the inner cavity;

[0013] A ventilation window is located at the connection between the lifting cylinder and the holding cylinder. It is used to control the opening and closing of the ventilation window as the lifting cylinder and the holding cylinder move up and down, thereby controlling the communication between the inner cavity and the external environment.

[0014] Preferably, the lifting cylinder is fitted with the inner cavity with a clearance to achieve lifting and sliding.

[0015] Preferably, a first limiting structure and a second limiting structure are provided between the inner cavity sidewall and the outer peripheral side of the lifting cylinder to limit the lifting range of the lifting cylinder relative to the gripping cylinder.

[0016] Preferably, the first limiting structure is a detachable limiting member disposed on the side wall of the lifting cylinder or the inner cavity, and the second limiting structure is a linear limiting hole disposed on the side wall of the inner cavity or the lifting cylinder, wherein the limiting member extends into the limiting hole to limit the vertical extension range of the lifting cylinder.

[0017] Preferably, the first limiting structure is a limiting part protruding from the outer wall of the lifting cylinder, and the second limiting structure is a limiting edge protruding from the inner wall of the inner cavity. The limiting part and the limiting edge stop cooperate to limit the extension and retraction position of the lifting cylinder.

[0018] Preferably, the first limiting structure and the second limiting structure are a limiting protrusion and a limiting groove, respectively attached to one of the inner sidewall of the inner cavity and the outer sidewall of the lifting cylinder. The limiting protrusion passes into the limiting groove to limit the telescopic sliding distance of the lifting cylinder.

[0019] Preferably, the connection position between the lifting cylinder and the gripping cylinder is provided with an annular guide distributed around the periphery of their contact surface to facilitate smooth sliding between the lifting cylinder and the gripping cylinder.

[0020] Preferably, the mounting base of the annular guide is an annular groove arranged around the inner or outer side wall of the lifting cylinder, and the annular guide is a sealing ring embedded in the annular groove.

[0021] Preferably, the bottom of the gripping cylinder is detachably provided with a bottom cover for opening and closing the bottom opening of the inner cavity.

[0022] Preferably, it also includes an intercepting filter covering the ventilation window, the intercepting filter being used to allow ventilation and intercept soot spillage.

[0023] The beneficial effects of this utility model are as follows:

[0024] The telescopic design of this utility model not only provides the ventilation environment required for combustion when the ventilation window is open, but also cuts off the connection between the inner cavity and the external environment when the ventilation window is closed, sealing the air to achieve the function of extinguishing smoke. The ventilation window hidden in the sealed state prevents soot from falling in the event of dumping or other accidents, ensuring the cleanliness of the surrounding environment.

[0025] In addition, its lift-up structure significantly reduces the vertical dimensions, making the product more compact and easy to carry in a bag or pocket.

[0026] Meanwhile, the simple operation of opening or closing the ventilation window with one hand improves the convenience of using the smoking device and also brings users a more elegant and modern visual experience. Attached Figure Description

[0044] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. Example

[0045] Please see Figures 1 to 5 This is a retractable and controllable portable smoking device, which is the preferred embodiment of the present utility model. It includes a grip tube 10, a lifting tube 20 and a top cover 30 assembled from bottom to top.

[0046] like Figure 2 , 3 As shown in Figure 4, the gripping tube 10 is cylindrical in shape, and a cylindrical inner cavity 11 with an opening at the top is formed inside.

[0047] In particular, in order to facilitate the creation of different personalized appearances, the grip tube 10 is composed of an inner tube 13 and an outer tube 14 nested together. The inner tube 13 is preferably made of metal and serves as the connection base between the various structures, while the outer tube 14 serves as the supporting component for personalized appearances, reflecting different appearance designs.

[0048] like Figure 2 , 3As shown in Figure 4, the lifting cylinder 20 is composed of two cylindrical structures that are coaxially distributed in a stepped shape and are stacked together. The lifting cylinder 20 is slidably inserted into the upper opening of the holding cylinder 10 and has a ventilation window 40 that can open and close the inner cavity 11 to communicate with the external environment as the lifting cylinder 20 moves up and down.

[0049] Specifically, the lifting cylinder 20 includes an upper cylinder 21 and a lower cylinder 22 that are coaxially arranged as an integral unit. A step is formed between the upper cylinder 21 and the lower cylinder 22. A cylindrical connecting cavity 23 is formed on the inner side of the upper cylinder 21 and the lower cylinder 22. The outer diameter of the lower cylinder 22 is smaller than that of the upper cylinder 21. A vent 40 is provided in the lower cylinder 22. The lower cylinder 22 and the inner cavity 11 are in a sliding cooperation for lifting.

[0050] In this embodiment, the ventilation window 40 is arranged in an arc shape around the outer periphery of the lower cylinder 22. The opening of the ventilation window 40 penetrates the outer wall and inner wall of the lower cylinder 22, thereby connecting the outside of the lower cylinder 22 and the connecting cavity 23. When the lower cylinder 22 rises to a position where the ventilation window 40 exceeds the upper end face of the grip cylinder 10, the external environment and the inner cavity 11 inside the grip cylinder 10 can be connected through the ventilation window 40. Conversely, when the lower cylinder 22 is slid down to a position where the ventilation window 40 is below the upper end face of the grip cylinder 10, the ventilation window 40 is completely closed by the grip cylinder 10.

[0051] In addition, in this embodiment, the ventilation window 40 is positioned near the upper cylinder 21 on the lower cylinder 22. Thus, the user only needs to press and slide the upper cylinder 21 upwards to raise the lifting cylinder 20 by a small stroke, which will allow the ventilation window 40 to be exposed, making it easier to control the opening and closing state of the ventilation window 40.

[0052] Among them, combined Figure 4 In order to achieve a limiting stop between the upper cylinder 21 and the gripping cylinder 10, the outer diameter D of the upper cylinder 21 is designed to be larger than the inner diameter D of the upper opening of the inner cavity 11. Thus, when the lifting cylinder 20 descends to the point where the upper cylinder 21 contacts the upper end face of the gripping cylinder 10, the bottom of the upper cylinder 21 and the upper opening of the gripping cylinder 10 form a stop, limiting the lifting cylinder 20 from descending further and defining the lowest lifting starting position of the lifting cylinder 20.

[0053] like Figure 2 , 3 As shown, in order to maintain the smoke-venting function of the ventilation window 40, block external dust, and prevent internal soot from escaping, an intercepting filter 50 can be installed on the inside or outside of the ventilation window 40 to allow smoke to escape, air to circulate, and to block the entry and exit of soot and dust.

[0054] In this embodiment, a cage-shaped intercepting filter 50 is provided on the inner side of the ventilation window 40. The outer diameter of the intercepting filter 50 is adapted to the inner diameter of the inner connecting cavity 23 of the lower cylinder 22. When the cage-shaped intercepting filter 50 is inserted into the lower cylinder 22, it can cover the inner area of ​​the ventilation window 40, forming an interception structure that allows smoke to escape, air to circulate, and blocks smoke and dust from entering and exiting.

[0055] In particular, the cage-like intercepting filter 50 in this embodiment can also serve as a corresponding receiving area. Fragrance for suppressing smoke odor is filled and placed in the inner area of ​​its cage-like structure. It permeates through the gaps in the intercepting filter 50 and is dispersed from the ventilation window 40 along with the smoke odor, thereby suppressing the smoke odor.

[0056] Furthermore, the intercepting filter 50 referred to in this embodiment is composed of several through holes or through grooves of specific shapes opened on a planar structure, and is not limited to a mesh structure only, so it is not considered a limitation on the intercepting filter.

[0057] like Figure 2 , 3 As shown in Figure 4, the lower cylinder 22 and the inner cavity 11 are fitted with a clearance. Specifically, the inner diameter of the inner cavity 11 is slightly larger than the outer diameter of the lower cylinder 22, which facilitates the insertion of the lower cylinder 22 and forms a lifting and sliding relationship with the inner cavity 11. By controlling the size of the clearance, the smoothness of the lifting fit between the lifting cylinder 20 and the gripping cylinder 10 can also be adjusted, as follows:

[0058] like Figure 3 , 4 As shown in Figure 5, in this embodiment, three annular guide members 60 are provided on the outer wall of the lower cylinder 22 along its axial direction. The three annular guide members 60 are distributed parallel to each other along the axial direction of the lower cylinder 22. In this embodiment, the annular guide member 60 is a rubber sealing ring. An annular groove 24 is provided around the outer periphery of the lower cylinder 22. The sealing ring is embedded in the annular groove 24. The outer ring of the sealing ring is in contact with the surface of the inner cavity 11. Thus, by setting the sealing ring, the up-and-down sliding process between the lower cylinder 22 and the inner cavity 11 can be guided, making its lifting process smoother. At the same time, the sealing ring also seals the gap between the inner cavity 11 and the lower cylinder 22, preventing the flue gas from escaping from the gap.

[0059] Specifically, in this embodiment, three sealing rings are respectively disposed on the upper side of the vent 40, the lower side of the vent 40, and the outer periphery of the lower cylinder 22 near the bottom. Thus, the sealing rings on the upper and lower sides of the vent 40 can prevent the smoke entering the gap from the vent 40 from escaping when the vent 40 is not raised. The cooperation of the three sealing rings can ensure that the lifting process between the lifting cylinder 20 and the holding cylinder 10 remains smooth and sealed.

[0060] like Figure 4, 5 As shown, it also includes a first limiting mechanism 70 and a second limiting structure 80. The first limiting structure 70 is a limiting member, and the second limiting structure 80 is a linear limiting hole 81 vertically distributed in the inner cylinder 13 and a fixing hole 82 that penetrates the side wall of the lower cylinder 22. The limiting member is pin-shaped, and its periphery is recessed inward to form a limiting annular groove 71 that is adapted to the diameter of the fixing hole. The end of the limiting member and located on one side of the limiting annular groove 71 forms a limiting end 72.

[0061] The limiting ring groove on the limiting component allows it to smoothly engage with the fixing hole 82. At this time, the limiting end 72 is located at the position protruding from the surface of the inner cylinder 13 and penetrating into the inner cavity 11. After the lower cylinder 22 penetrates into the inner cavity 11, the limiting hole 81 on the lower cylinder aligns with the fixing hole 82. At this time, the limiting end 72 can just penetrate into the limiting hole 81. Thus, when the lifting cylinder 20 slides up and down, under the restriction of the limiting end, it can only slide within the vertical extension distance of the limiting hole 81.

[0062] Alternatively, the position of the fixing hole 82 can be interchanged with that of the limiting hole 81, and the orientation of the limiting member will be reversed accordingly, which can also limit the lifting range of the lifting cylinder 20.

[0063] like Figure 4 , 5 As shown, in order to further improve the stability of the lifting and sliding between the lower cylinder 22 and the inner cavity 11, two first limiting structures 70 are evenly arranged around the inner cavity 11 and symmetrically distributed along the diameter of the inner cavity 11, and two second limiting structures 80 are evenly arranged around the outer periphery of the lower cylinder 22 and are opposite to the position of the first limiting structure 70.

[0064] like Figure 2 , 3 As shown in Figure 5, the top cover 30 is installed on the upper end of the lifting cylinder 20 and has a cigarette insertion hole 31 that allows a cigarette to be inserted into the inner cavity 11.

[0065] In this embodiment, in order to connect and fix the top cover 30 and the lifting cylinder 20, a connecting seat 32 is connected to the lower end of the top cover 30. The cigarette insertion hole 31 is centrally located at the center of the top cover 30 and extends integrally to the bottom surface of the connecting seat 32 to form a communication area with the communicating cavity 23 and the inner cavity 11. The connecting seat 32 is threadedly connected to the communicating cavity 23 on the inner side of the upper cylinder 21, thereby realizing the detachable fixation between the top cover 30, the connecting seat 32 and the lifting seat.

[0066] In this embodiment, the outer diameter D of the upper cylinder 21 is adapted to the outer diameter of the grip cylinder 10 and the outer diameter of the top cover 30, so that the entire smoking device forms a flat state, maintaining the overall aesthetics of the smoking device while also making it easy for the user to hold.

[0067] like Figure 4 ,5 As shown, in order to further facilitate the collection and cleaning of soot, a bottom cover 12 is installed at the bottom of the grip tube 10. Thus, by opening the bottom cover 12, the bottom of the inner cavity 11 can be opened or closed, making it convenient to clean the soot and other garbage accumulated in the inner cavity 11.

[0068] Furthermore, such as Figure 3 , 4 As shown in Figure 6, an air inlet ring 16 is provided at the bottom of the outer cylinder 14. The air inlet ring 16 is fitted onto the bottom of the inner cylinder 13. The outer diameter of the air inlet ring 16 is the same as that of the outer cylinder 14, so that the air inlet ring 16 is flush with the outer surface of the outer cylinder 14, thereby achieving an aesthetic purpose.

[0069] Several air intake holes 161 are formed through the outer periphery of the air intake ring 16, serving as the basis for air intake.

[0070] To facilitate air intake into the inner cavity 11, the lower half of the inner wall of the inner cylinder 13 is narrowed to form a protrusion 131 protruding from the wall of the inner cavity 11. Several air guide channels 132 are formed on the inner wall of the inner cavity 11 above the protrusion 131, extending downwards to the bottom of the protrusion 131. The depth of the air guide channels 132 is the same as the wall thickness of the upper half of the inner cylinder 13, thus allowing the outer side of the air guide channels 132 to communicate with the inner wall of the outer cylinder 14. Furthermore, the air guide channels 132 are located within the protrusion 131. An air inlet 133 is formed at the upper end of the outer cylinder 14, thereby allowing the air guide channel 132 to communicate with the external environment below the bottom of the outer cylinder 14. Furthermore, the lowest position of the air guide channel 132 is designed such that when the air inlet sleeve 16 is fitted onto the inner bottom of the inner cylinder 13, the air inlet hole 161 corresponds to the lowest position of the air guide channel 132, allowing external air to enter the air guide channel 132 along the air inlet hole 161, rise along the air guide channel 132 to the air inlet 133, and then enter the inner cavity 11.

[0071] Furthermore, in order to control the opening and closing of the air passage 132 in conjunction with the raising and lowering of the lifting cylinder 20 and the opening and closing of the vent 40, the uppermost position of the protrusion 131 is designed such that when the lifting cylinder 20 is fully lowered into the inner cavity and at its lowest position, the lowest position of the lower cylinder 22 is exactly in contact with the upper end face of the protrusion 131. This allows the air inlet 133 to be sealed when the lifting cylinder 20 is lowered into the inner cavity 11, preventing the smoke from escaping when the device is not in use. When the device is in use, the lifting cylinder 20 is raised, and the vent 40 is exposed. At this time, the lower cylinder 22 rises to a position higher than the air inlet 133, and the air inlet 133 is reconnected with the inner cavity 11. This allows the air inlet 161, the air passage 132, and the air inlet 133 to form a passage, facilitating the introduction of fresh air from the bottom of the device when the user smokes, thereby actively circulating the air in the inner cavity 11.

[0072] Specifically, in this embodiment, there are several air inlets 161 along the periphery of the air inlet collar 16 and they are divided into two groups. The two groups of air inlets 161 are symmetrically distributed about the center of the air inlet collar 16. The number and position of the air guide channel 132 and the air inlet point 133 correspond to the air inlets 161.

[0073] like Figure 4 As shown, in this embodiment, the bottom cover 12 is divided into a disc-shaped bottom 121 and a side portion 122 that is vertically protruding from the axial upper side of the bottom 121. The side portion 122 is cylindrical, and a dust collection groove 123 is formed on its inner side. The outer diameter of the side portion 122 is adapted to the inner diameter of the protrusion 131, and the two are connected by threads or snaps. Thus, the bottom cover 12 can be fixedly connected to the lower end of the holding cylinder 10 to realize the functions of dust collection and dust removal. Example

[0074] Please see Figure 7 This is a retractable and controllable portable smoking device as a second embodiment of the present invention. The difference from the first embodiment is that the lifting cylinder 20 is sleeved on the outer side of the upper end of the holding cylinder 10.

[0075] Specifically, the inner cylinder 13 of the gripping cylinder 10 is designed to be taller than the outer cylinder 14, so that the gripping cylinder 10 forms a protruding insertion base at the top, and the inner side of the lifting cylinder 20 forms an insertion groove that is compatible with the outer wall of the inner cylinder 13 (i.e., the same position as the figure numeral 23).

[0076] In this embodiment, the ventilation window 40 is opened on the outer side wall of the inner cylinder 13 and is located above the uppermost end of the outer cylinder 14. Thus, when the lifting cylinder 20 is inserted into the outer side of the inner cylinder 13, a vertical telescopic sliding relationship is formed. When the lifting cylinder 20 descends to contact the upper end face of the outer cylinder 14, it completely covers the ventilation window 40, cutting off the communication between the inner cavity 11 and the external environment. Conversely, when the ventilation window 20 rises to expose the ventilation window 40, the communication between the inner cavity 11 and the external environment is opened, providing the ventilation environment required for combustion smoke. Example

[0077] Please see Figure 8 This is a retractable and controllable portable smoking device as a third embodiment of the present invention. The difference from the first embodiment is that the first limiting structure 70 is a limiting part protruding from the outer periphery of the lower cylinder 22, and the second limiting structure 80 is a limiting edge protruding from the inner wall of the inner cavity 11. Both the limiting part and the limiting edge protrude toward the gap between the lower cylinder 22 and the inner cavity 11, and the limiting part is located below the limiting edge. Thus, when the lifting cylinder 20 rises, the upper end face of the limiting part contacts the lower end face of the limiting edge to form a limit, at which time the lifting cylinder 20 is at its highest raised position.

[0078] In this embodiment, the limiting edge is annular and is formed around the opening at the upper end of the inner cavity 11. The limiting part is also annular and is arranged around the bottom of the outer periphery of the lower cylinder 22.

[0079] Combination Figure 8 The limiting part, together with the stepped structure of the upper cylinder 21, forms the upper and lower positions that cooperate with the limiting edge. When the lifting cylinder 20 descends to the point where the stepped structure at the bottom of the upper cylinder 21 contacts the limiting edge, this is the lowest position of the lifting cylinder 20.

[0080] In addition, combined Figure 9 To prevent the lifting cylinder 20 from rotating circumferentially and to enable it to rise and fall linearly in the vertical direction, a positioning part 25 is formed by protruding from the outer wall of the lower cylinder 22 below the limiting part. The side wall of the inner cavity 11 is recessed inward to form a positioning groove 26 that fits into the positioning part 25. The positioning groove 26 extends and is distributed in the vertical direction. Thus, under the limiting cooperation of the positioning part 25 and the positioning groove 26, the vertical extension and retraction of the lifting cylinder 20 is realized, improving its operating feel.

[0081] In particular, the positions of the positioning part 25 and the positioning groove 26 can also be reversed, that is, the positioning groove 26 is set on the side wall of the lower cylinder 22 and the positioning part 25 is set on the side wall of the inner cavity 11. In this case, it can be easily achieved by simply extending the height of the lower cylinder 22, and there is no restriction here. Example

[0082] Please see Figure 10 This is a retractable and controllable portable smoking device as an embodiment four of the present invention. The difference from embodiment one is that the intercepting filter 50 is sheet-shaped and curved to form an arc shape that adapts to the side wall of the communicating cavity 23 inside the lower cylinder 22. Thus, the intercepting filter 50 is attached and fixed to the inner side wall of the ventilation window 40, which can form an interception structure that allows smoke to escape, air to circulate, and blocks soot and dust from entering and exiting. Example

[0083] Please see Figure 11-12 This is a retractable and controllable portable smoking device as a fifth embodiment of the present invention. The difference from the first embodiment is that the number of the first limiting structure 70 and the second limiting structure 80 is set to two, and they are radially symmetrically distributed about the inner cavity 11.

[0084] In Embodiment 1, the first limiting structure 70 is a limiting protrusion, and the second limiting structure 80 is a limiting groove. During the continuous raising and lowering of the ventilation window, the limiting protrusion is prone to wear and tear during repeated contact with the edge of the limiting groove. By increasing the number and arrangement of the first limiting structure 70 and the second limiting structure 80, the durability of the lifting and lowering cooperation structure between the lifting cylinder 20 and the gripping cylinder 10 can be further enhanced, allowing users to obtain a lasting comfortable experience.

[0085] In addition, see Figure 12 The first limiting structure 70 and the second limiting structure 80 can also be set in three sets, evenly distributed along the periphery of the inner cavity 11, so that the durability of the lifting and lowering cooperation structure between the lifting cylinder 20 and the gripping cylinder 10 is further enhanced.

[0086] As an extension, it is foreseeable to increase the number and arrangement of the first limiting structure 70 and the second limiting structure 80, which is also within the protection scope of this scheme, and will not be elaborated here. Example

[0087] This is a retractable and controllable portable smoking device as an embodiment of the present invention. The difference from embodiment one is that the annular guide 60 is an elastic steel wire ring.

[0088] The elastic steel wire ring is formed by bending a flexible steel wire into a notched ring. On the one hand, the above structure facilitates the installation of the annular guide 60 into the annular slot 24. On the other hand, compared with the method of using rubber sealing rings, the steel wire structure has more stable and wear-resistant properties, can adapt to more lifting contacts, and fully extend the service life of the lifting structure. Example

[0089] like Figure 13 As shown, this is a retractable and controllable portable smoking device as a sixth embodiment of the present invention. The difference from the first embodiment is that the first limiting structure 70 is a limiting protrusion, and the second limiting structure 80 is a limiting groove opened along the axial direction of the lower cylinder 22. The limiting protrusion passes into the limiting groove to limit the extension and retraction of the lifting cylinder 20 within the extension distance of the limiting groove.

[0090] The limiting protrusion and the limiting groove are matched as follows: a U-shaped hollow groove 15 is opened on the inner cylinder 13 of the gripping cylinder 10, so that the part inside the hollow groove 15 forms a sheet-like structure with one end fixed and the other end movable. When the lower cylinder 22 is inserted into the inner cavity 11, when the limiting groove moves to the position covering the aforementioned sheet-like structure, the movable end of the sheet-like structure is pressed inward from the outside of the inner cylinder 13, so that it bends and deforms and fits into the range of the limiting groove. At this time, the bent sheet-like structure forms the aforementioned limiting protrusion, which cooperates with the limiting groove to limit the telescopic distance of the lifting cylinder 20, so that the vertical movement range of the lifting cylinder 20 is limited to the range of the limiting groove. Finally, the structure of the inner cylinder 13 is modified and hidden by the outer cylinder 14, completing the assembly process between the lifting cylinder 20 and the gripping cylinder 10.

[0091] In this embodiment, the bending angle of the sheet structure is preferably 90°, so that it is completely perpendicular to the side wall of the inner cylinder 13, forming a vertical telescopic limit with the limiting groove.

[0092] Alternatively, the positions of the limiting protrusion and the limiting groove can be reversed, i.e., the limiting protrusion is formed on the side wall of the lower cylinder 22 and the limiting groove is formed on the side wall of the inner cylinder 13. This is not a restriction on the setting position of the limiting protrusion and the limiting groove.

[0093] The beneficial effects of this utility model are as follows:

[0094] The telescopic structure design adopted in this utility model can not only provide the ventilation environment required for combustion when the ventilation window 40 is open, but also cut off the connection between the inner cavity 11 and the external environment when the ventilation window 40 is closed, thereby sealing the air for smoke extinguishing. The ventilation window 40, which is hidden in the sealed state, can also prevent soot from falling in case of dumping or other accidents, ensuring the cleanliness of the surrounding environment.

[0095] In addition, this utility model adopts a partially telescopic overlapping structure of the lifting cylinder 20 and the gripping cylinder 10, which effectively reduces the overall size of the smoking device in the vertical direction, achieving a more streamlined and compact design that is easy to carry and store. On the other hand, by utilizing the cooperation between the lifting cylinder 20 and the gripping cylinder 10, the exposure or concealment of the ventilation window 40 can be controlled by a simple lifting action, allowing users to easily operate with one hand without the need for two-handed cooperation, greatly simplifying the operation process and improving the convenience of using the smoking device.

[0096] The smoking device created by this invention is particularly suitable for various mobile scenarios, such as indoors, in a vehicle, or outdoors, ensuring that users can conveniently and quickly use the smoking device in different environments, while maintaining good ash and smoke management.

[0097] In summary, this utility model not only optimizes the size of the smoking device, making it more compact and lightweight, but also improves the ease of operation and user experience through the lifting design, meeting the needs of modern users for convenience and efficiency.

[0098] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
