Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to a spiral connection mechanism and a low-temperature smoking device. Background Technology

[0002] Low-temperature smoking devices are electronic devices designed to simulate the experience of traditional cigarettes, but typically do not involve tobacco combustion. They generate an aerosol by heating it, producing an inhalable aerosol that mimics the smoking experience of a traditional cigarette.

[0003] Over time, grease will accumulate on the inner wall of a low-temperature vaping device, so it needs to be cleaned regularly. After opening the cleaning cover, you can use a brush / cotton swab or other device to clean the inner cavity from the bottom. The existing cleaning cover and the bottom of the low-temperature vaping device are connected by a plug, which makes it easy for the cleaning cover to fall off during use.

[0004] Therefore, it is urgent to study a spiral connection mechanism and a low-temperature fume appliance to solve the above problems. Utility Model Content

[0017] The protrusion is made of stainless iron, aluminum alloy, or zinc alloy.

[0018] As an optional technical solution for a spiral connection mechanism, the connection assembly further includes a connection body connected to the protrusion. The connection assembly includes two mating parts, with a portion of the mating parts embedded in the connection body and a portion exposed on the outside of the connection body to form the protrusion.

[0019] As an optional technical solution for a spiral connection mechanism, the connection assembly further includes a connection body connected to the protrusion. The connection assembly includes a connection ring, with two protrusions disposed on the outer side of the connection ring. The connection ring is sleeved and fixed to the outer periphery of the connection body.

[0020] As an optional technical solution for a spiral connection mechanism, the connection assembly further includes a connection body connected to the protrusion. The connection assembly includes a connection ring and two mating parts. The two mating parts are located on the outside of the connection ring. The connection ring is injection molded inside the connection body. The mating parts are partially located inside the connection body and partially located on the outside of the connection body to form the protrusion.

[0021] As an optional technical solution for the spiral connection mechanism, the connection assembly further includes a connection body connected to the protrusion. The protrusion is located at one end of the connection body, and two limiting rings are arranged at intervals along the extension direction of the connection body at the other end of the connection body. Both limiting rings are sleeved on the outer periphery of the connection body and form an annular limiting groove with the connection body. The spiral connection mechanism also includes a sealing ring, which is sleeved in the limiting groove.

[0022] A low-temperature smoke appliance includes a housing and a spiral connecting mechanism as described in any of the above technical solutions. The housing has a receiving cavity and a receiving opening communicating with the receiving cavity. A base is installed on the housing to seal the receiving opening. The base has a mounting groove, and the spiral groove is disposed in the mounting groove. The connecting assembly further includes a connecting body connected to the protrusion. The bottom of the mounting groove has a first channel penetrating the base, and the connecting body has a second channel penetrating along its own axis.

[0038] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0039] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0040] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0041] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0042] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0043] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0044] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0045] like Figures 1 to 7As shown, this embodiment provides a spiral connection mechanism, which includes a base 100 and a connecting assembly 200. The base 100 includes a first connecting portion 12a; the connecting assembly 200 includes a second connecting portion 22a; one of the first connecting portion 12a and the second connecting portion 22a is a spiral groove 120, and the other is a protrusion 220. When one of the connecting assembly 200 and the base 100 is screwed and rotated relative to the other, the connecting assembly 200 moves in or out along the centerline of the base 100. This spiral engagement effectively reduces the probability of the connecting assembly 200 separating from the base 100. Furthermore, the spiral engagement of the protrusion 220 and the spiral groove 120 simplifies the connection structure and reduces production costs.

[0046] The base 100 includes a mounting groove 120, and a first connecting part 12a is disposed inside the mounting groove 120; the connecting assembly 200 includes a connecting body 210 connected to the second connecting part 22a; when one of the connecting assembly 200 and the base 100 is screwed and rotated relative to the other, the connecting assembly 200 moves along the center line of the base 100 to be screwed into or out of the mounting groove 110.

[0047] Since the connecting component 200 needs to be screwed into the mounting groove 110, the diameter of the connecting component 200 is smaller than the diameter of the mounting groove 110. To improve the convenience of structural design, in some embodiments, the first connecting part 12a is a spiral groove 120, and the second connecting part 22a is a protrusion 220. That is, the base 100 is provided with a spiral groove 120; the connecting component 200 is provided with a protrusion 220. Of course, in other embodiments, the protrusion 220 can be provided on the base 100; the spiral groove 120 can be provided on the connecting component 200.

[0048] In some embodiments, there are two spiral grooves 120 and two protrusions 220. The cooperation of the two protrusions 220 and the two spiral grooves 120 helps to improve the twisting speed, simulates the connection effect of a double-ended thread, and greatly improves the screwing efficiency. By setting the pitch, the connecting component 200 and the base 100 can be screwed into the mounting groove 110 by twisting them relative to each other by 1 turn or half a turn.

[0049] The two helical grooves 120 or the two protrusions 220 are centrally symmetrical. This arrangement helps to improve the symmetry of the fit between the protrusions 220 and the helical grooves 120 and the balance of forces, thereby helping to reduce the possibility of the connecting assembly 200 deviating during rotation, reducing the chance of jamming, and improving the smoothness and reliability of the screw connection.

[0050] In some embodiments, the protrusion 220 and the connecting body 210 are integrally formed. Both the protrusion 220 and the connecting body 210 are made of metal. The metal protrusion 220, integrally formed with the connecting body 210, has reliable strength and helps reduce the risk of breakage of the protrusion 220 due to violent rotation. The protrusion 220 is columnar, and its extension direction is perpendicular to the extension direction of the connecting body 210.

[0051] For example, the protrusions 220 and the connecting body 210 are made of the same material, specifically stainless steel, aluminum alloy, or zinc alloy. In some embodiments, the connecting body 210 can be made of a material such as stainless steel that can be magnetically attracted. In this embodiment, the connecting body 210 is columnar, and the two protrusions 220 are arranged symmetrically about the axis of the connecting body 210.

[0052] In some embodiments, combined with Figure 5 As shown, the connecting assembly 200 includes two mating parts 230. Parts of the mating parts 230 are embedded within the connecting body 210, while other parts protrude from the outside of the connecting body 210 to form protrusions 220. The sidewall of the mounting groove 110 has two spiral grooves 120 arranged around the centerline of the mounting groove 110. The mating parts 230 and the connecting body 210 are made of different materials, and the hardness of the mating parts 230 is greater than that of the connecting body 210. For example, the connecting body 210 can be made of plastic or rubber, and the mating parts 230 can be made of metal. The mating parts 230 and the connecting body 210 are connected by injection molding or hot-melt welding.

[0053] To improve connection strength, in some embodiments, combined with Figure 6 As shown, the connecting assembly 200 includes a connecting ring 240, with two protrusions 220 disposed on the outer side of the connecting ring 240. The connecting ring 240 is sleeved and fixed to the outer periphery of the connecting body 210. The sidewall of the mounting groove 110 has two spiral grooves 120 arranged around the center line of the mounting groove 110. The connecting ring 240 and the protrusions 220 have the same hardness, both greater than the hardness of the connecting body 210. Exemplarily, the connecting ring 240 and the protrusions 220 are integrally formed and are made of metal. The connecting body 210 can be made of plastic. The connecting ring 240 and the connecting body 210 are connected by adhesive bonding or ultrasonic riveting.

[0054] In some embodiments, combined with Figure 7As shown, the connecting assembly 200 includes a connecting ring 240 and two mating parts 230. The two mating parts 230 are located on the outer side of the connecting ring 240 and are symmetrically arranged about the axis of the connecting ring 240. The connecting ring 240 is injection molded inside the connecting body 210. The mating parts 230 are partially located inside the connecting body 210 and partially located on the outer side of the connecting body 210 to form a protrusion 220. The connecting ring 240 and the mating parts 230 have the same hardness, both greater than that of the connecting body 210. For example, the connecting ring 240 and the protrusion 220 are integrally molded and are made of metal. The connecting body 210 can be made of plastic. A portion of the connecting ring 240 and the mating parts 230 are disposed inside the connecting body 210 by injection molding or other methods. This arrangement results in a higher connection strength between the mating parts 230 and the connecting body 210.

[0055] Regarding the formation of the spiral grooves 120, in some embodiments, the sidewall of the mounting groove 110 is provided with at least two spiral protrusions 130 arranged around the center line of the mounting groove 110 to form at least two spiral grooves 120. The above arrangement helps to appropriately increase the diameter of the mounting groove 110 so as to adaptively increase the diameter of the connecting body 210, thereby making it easier for the user to hold.

[0056] To improve the sealing of the mounting groove 110, in some embodiments, a protrusion 220 is provided at one end of the connecting body 210, and two limiting rings 211 are arranged at intervals along the extension direction of the connecting body 210 at the other end of the connecting body 210. Both limiting rings 211 are sleeved on the outer periphery of the connecting body 210, and the two limiting rings 211 and the connecting body 210 form an annular limiting groove 212. The spiral connection mechanism also includes a sealing ring, which is sleeved in the limiting groove 212, and the outer periphery of the sealing ring abuts against the circumferential sidewall of the mounting groove 110. This arrangement allows the sealing ring to seal between the sidewall of the mounting groove 110 and the connecting body 210, thereby preventing impurities in the mounting groove 110 from flowing out through the gap between the mounting groove 110 and the connecting body 210; at the same time, along the axial direction of the connecting body 210, the sealing ring is limited between the two limiting rings 211, which helps to ensure that the sealing ring moves synchronously with the connecting body 210 on the axis of the connecting body 210.

[0057] Combination Figure 8As shown, this embodiment also provides a low-temperature smoking device, which includes a housing 300 and a spiral connection mechanism as described in any of the above embodiments. The housing 300 has a receiving cavity 310 and a receiving opening communicating with the receiving cavity 310. A base 100 is installed on the housing 300 to seal the receiving opening. The bottom of the mounting groove 110 has a first channel 140 that passes through the base 100, and the connecting body 210 has a second channel 213 that passes through it along its own axis. Along the gas flow direction, the second channel 213, the first channel 140, and the receiving cavity 310 are connected in sequence. The receiving cavity 310 has an aerosol generating mechanism. During the user's inhalation of the low-temperature smoking device, the gas enters the receiving cavity 310 after passing through the second channel 213 and the first channel 140, and brings the generated aerosol to the user. When cleaning is required, the connecting body 210 can be unscrewed from the mounting groove 110 to expose the first channel 140. The brush, as an accessory, can pass through the mounting groove 110 and the first channel 140 and extend into the accommodating cavity 310 for cleaning.

[0058] In some embodiments, the connecting body 210 can be made of a material such as stainless steel that can be magnetically attracted. The connecting body 210 is provided with a second channel 213, and a magnet can be embedded in the brush handle. When the brush handle is inserted into the second channel 213, the brush handle and the connecting body 210 can be attracted by magnetic force to form a whole, so that the brush can be operated by holding the connecting body 210.

[0059] In this embodiment, a portion of the connecting ring 240 and the mating part 230 are located inside the connecting body 210, and a portion of the mating part 230 is located outside the connecting body 210, forming a protrusion 220. The connecting ring 240 is sleeved on the outer periphery of the second channel 213 to avoid the second channel 213 and ensure the unobstructed air passage.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
