Description

Technical Field

[0001] This application relates to the field of incense burning apparatus technology, and more specifically to an incense stick inserting device and an incense burning apparatus. Background Technology

[0002] As a traditional incense product, incense sticks usually need to be supported and fixed with incense holders or incense burners during use to keep the incense sticks in a stable state and complete continuous smoldering.

[0003] Existing incense stick holders are usually made of materials such as metal, ceramic or stone and have a socket that fits the incense stick. When in use, the end of the incense stick is inserted into the socket to fix it. In order to ensure stable insertion, existing incense holders usually rely on the matching relationship between the inner diameter of the socket and the diameter of the incense stick, so that the incense stick is positioned by the friction between the inner wall of the socket and the outer surface of the incense stick.

[0004] However, in actual use, to ensure stable insertion, the bottom of the socket is usually a closed structure or forms a large support contact surface. When the incense stick is burning near the end, the heat is easily dissipated through the socket due to the large contact area between the incense root and the bottom of the socket. At the same time, the bottom and side walls of the socket obstruct air circulation, making it difficult for the remaining incense root to continue smoldering. This results in unburned incense root residue, which not only wastes the incense stick but also requires manual cleaning, affecting its use. Summary of the Invention

[0005] This application provides an incense stick insertion device and an incense burning appliance, which can stably hold incense sticks of different diameters while reducing the contact area between the incense stick and the insertion structure, improving the air circulation conditions in the combustion zone, enabling the incense stick to maintain stable smoldering and ensuring that the end of the incense stick burns out completely, thereby improving the utilization rate of the incense stick.

[0006] In a first aspect, this application provides an incense stick insertion device, comprising: an inlet portion having an insertion hole extending vertically and having a hollow shape; one or more clamping portions connected to the inlet portion and arranged obliquely along the height direction of the inlet portion, the one or more clamping portions having at least two clamping free ends extending toward the center of the insertion hole, the clamping free ends being made of a low thermal conductivity elastic material; and a receiving portion disposed at the bottom of the insertion hole and forming a hollow receiving space for holding at least part of the incense stick and, when the incense stick burns below the clamping free ends, accommodating the remaining incense stick roots and supporting the incense stick roots to continue burning until they are completely burned; wherein, the at least two clamping free ends are capable of elastically opening when the incense stick is inserted and clamping the incense stick from different directions under elastic recovery, so that the incense stick is kept in position along the axial direction of the insertion hole, while forming a gap between the incense stick and the clamping portion.

[0007] In one alternative of the first aspect, the clamping part is symmetrically arranged extending along the insertion hole towards the receiving part and forms a clamping space for clamping incense sticks in at least part of it. The clamping free end of the clamping part is in the shape of a barb, a hook, or a straight needle to make point contact with the incense sticks and to allow the burning heat of the incense sticks to preheat the clamping free end.

[0008] In one alternative of the first aspect, the plurality of at least two clamping portions include: a plurality of clamping free ends, which are offset along the height direction of the inlet portion and / or the circumferential direction of the insertion hole, so as to act on different positions of the incense stick and form a clamping space.

[0010] In one alternative of the first aspect, the plurality of clamping free ends are staggered along the height direction of the inlet and distributed circumferentially along the insertion hole, so that different clamping free ends act on different axial positions of the incense stick to form multi-point or hierarchical clamping and positioning.

[0011] In one alternative embodiment of the first aspect, the clamping portion further includes: one or more limiting members, which are respectively disposed on the one or more clamping portions and have at least two limiting free ends, the limiting free ends being arranged obliquely along the height direction of the inlet portion and extending at least partially into the insertion hole extension area, for limiting the position of the inserted incense stick and preventing the incense stick from tilting.

[0012] In one alternative of the first aspect, the clamping part is made of spring steel, stainless steel, titanium alloy, nickel-titanium alloy or elastic polymer material, so that the clamping part returns to its initial state after the incense is burned to the clamping position.

[0013] In one alternative of the first aspect, at least two of the plurality of limiting free ends are located on the same horizontal plane or are offset along the height direction of the inlet to form a limiting space that restricts the position of the inserted incense stick and prevents the incense stick from tilting.

[0014] In one alternative embodiment of the first aspect, the receiving portion includes: at least two first connectors connected at their ends to form a receiving space of planar, concave, or arc-shaped form for receiving the remaining incense stick and supporting the incense stick to continue burning until it is completely burned out; and contact points evenly distributed on the at least two first connectors and located within the receiving space for reducing the contact area between the remaining incense stick and the at least two first connectors; wherein the contact area between the receiving space and the incense stick is smaller than the bottom area of ​​the socket and an airflow space is formed between the receiving space and the socket.

[0015] In one alternative of the first aspect, the at least two first connectors are connected in at least one region by one or more second connectors to prevent the incense stick residue from escaping the receiving space.

[0017] In one alternative of the first aspect, the exterior of the at least two clamping portions and the receiving portion is coated with one or more layers of a low thermal conductivity material coating.

[0018] In one alternative of the first aspect, a support portion is further included, which is connected to the inlet portion for at least partially installing the incense stick insertion device into the incense holder of the incense burner.

[0035] To facilitate understanding of the technical solutions provided in this application, the relevant terms are explained below.

[0036] It should be noted that the terminology used in the implementation section of this application is only for explaining the embodiments of this application and is not intended to limit this application.

[0037] For example, the term "and / or" in this article simply describes the relationship between related objects, indicating that three relationships can exist. For instance, A and / or B can represent: A alone, A and B simultaneously, and B alone. The term "at least one" simply describes the combination relationship of listed objects, indicating that one or more can exist. For instance, at least one of the following: A, B, C can represent the following combinations: A alone, B alone, C alone, A and B simultaneously, A and C simultaneously, B and C simultaneously, and A, B, and C simultaneously. The term "multiple" refers to two or more. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0038] For example, the term "corresponding" can indicate a direct or indirect correspondence between two things, or an association between them, or a relationship of instruction and being instructed, configuration and being configured, etc. The term "when..." can be interpreted as "if," "suppose," "when," or "in response," etc. The terms "first," "second," "third," "fourth," "A," "B," etc., are used to distinguish different objects, not to describe a specific order. The terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0039] Currently, existing incense holder structures still have shortcomings in practical use. To ensure stable placement, the bottom of the insertion hole 10a is usually a closed structure or forms a large supporting contact surface. When the incense stick is burning near the end, due to the large contact area between the incense root and the bottom of the insertion hole 10a, heat is easily conducted away through the insertion hole 10a. At the same time, the bottom and side walls of the insertion hole 10a obstruct airflow, making it difficult for the remaining incense root to continue smoldering. This results in unburned incense root residue, which not only wastes the incense stick but also requires manual cleaning, affecting its use.

[0040] Furthermore, since existing incense holders mainly rely on the diameter of the 10a insertion hole to position the incense sticks, and the diameters of incense sticks produced by different manufacturers vary, when the incense stick diameter is smaller than the inner diameter of the 10a insertion hole, it is easy for it to tilt, shake, or even fall off; while when the incense stick diameter is larger than the inner diameter of the 10a insertion hole, it is difficult to insert. Therefore, different specifications of incense sticks often require incense holders with different hole diameters. In addition, existing incense holders usually rely on the side wall of the 10a insertion hole to form a large contact area with the incense stick for fixation. During the burning process, the large contact area between the side wall and the incense stick not only increases heat conduction but may also affect the air circulation near the burning area, which is not conducive to the continuous and stable smoldering of the incense stick, and may even cause the incense stick to go out when it burns close to the clamping position.

[0041] Figure 1A first perspective structural schematic diagram of an exemplary incense stick holder according to some embodiments of this application is shown; Figure 2 A second perspective structural schematic diagram of an exemplary incense stick insert device according to some embodiments of this application is shown.

[0042] Therefore, for reference Figure 1 and Figure 2 As shown. To solve the above-mentioned technical problems, this application relates to an incense stick inserting device 1, which is placed on the incense holder of an incense burning device; the incense stick inserting device 1 includes at least an inlet portion 10, one or more clamping portions 20 and a receiving portion 30.

[0043] <Introduction Section 10> Figure 3 A top view of an exemplary incense stick holder according to some embodiments of this application is shown.

[0044] refer to Figure 3 As shown. The inlet part 10 serves as the insertion part for the incense stick, and it is provided with a plug hole 10a extending in the vertical direction. The plug hole 10a adopts a through hole design and is provided with an insertion port 11 and a connecting port 12. The insertion port 11 is used for inserting the incense stick, and the connecting port 12 communicates with the clamping space 21 of at least two clamping parts 20 so that the inserted incense stick can extend into the clamping space 21.

[0045] Specifically, the inlet portion 10 is made of materials including but not limited to metals, ceramics, polymer composites, or combinations thereof. In this application, the inlet portion 10 is exemplarily made of materials with low thermal conductivity and high heat resistance, such as titanium alloys, stainless steel, alumina ceramics, silicon nitride ceramics, etc., to reduce the rate at which heat is transferred from the incense stick to the inlet portion 10. The insertion hole 10a is generally through-hole, and its cross-section is exemplarily circular, elliptical, polygonal, or other shapes suitable for inserting the incense stick. In this application, the insertion hole 10a is exemplarily circular. The sidewalls and / or bottom of the insertion hole 10a are at least partially hollowed out. The sidewalls of the insertion hole 10a may be provided with one or more through holes, through slots, grid structures, or spaced support ribs to improve airflow near the combustion zone.

[0046] In some examples of this application, the maximum inner diameter of the socket 10a is greater than the maximum outer diameter of the compatible incense stick, so that a preset gap is formed between the side wall of the socket 10a and the inserted incense stick, and the preset gap is continuously distributed circumferentially along the inner wall of the socket 10a. For example, when the diameter of the compatible incense stick is in the range of 1mm to 5mm, the inner diameter of the socket 10a can be set to 2mm to 6mm to accommodate the insertion requirements of incense sticks of different specifications. Those skilled in the art should understand that the above dimensions are only examples and do not constitute a limitation on the scope of protection of this application.

[0047] Since the inner diameter of the socket 10a is larger than the outer diameter of the incense stick, after the incense stick is inserted, the side wall of the socket 10a does not participate in the radial positioning of the incense stick. Instead, the incense stick is positioned and held by at least two clamping parts 20.

[0048] In some examples of this application, the inlet 10 adopts a ring structure to form the insertion port 11. The inlet 10 is connected to the structure below only by a few connecting ribs, so that most of the area of ​​the insertion hole 10a remains open, thereby reducing the absorption of heat from the burning incense by the inlet 10.

[0049] In some examples of this application, in order to reduce the influence of the inlet portion 10 on the burning area of ​​the incense stick, an insulation layer is provided on the surface of the inlet portion 10. The insulation layer adopts a single-layer or multi-layer structure formed by ceramic coating, oxide layer, high-temperature resistant resin layer or other high-temperature resistant insulation materials, and its preparation method includes, but is not limited to, spraying, chemical deposition, electrophoretic deposition or heat treatment.

[0050] During the use of incense sticks, the incense stick is first inserted into the socket 10a through the insertion port 11 and radially positioned under the action of the clamping part 20. As the incense stick continues to smolder, its combustion area gradually moves downward. Since a preset gap is maintained between the socket 10a and the incense stick, and the inlet part 10 is made of a low thermal conductivity material and has at least a partially hollow structure, the conduction and absorption of combustion heat by the inlet part 10 can be reduced, while facilitating the entry of air into the combustion area.

[0051] It is understood that the description of the number, shape, size, hollowing method, material and insulation layer structure of the insertion hole 10a of the inlet part 10 in this application is only an example. Those skilled in the art can make equivalent substitutions or combinations without departing from the concept of this application. As long as the structure can realize the insertion of the incense stick and reduce the absorption of heat from the burning of the incense stick, it should be regarded as an equivalent embodiment of this application.

[0052] <One or more clamping parts 20> Figure 4 A side view of an exemplary incense stick holder according to some embodiments of this application is shown. Figure 5 A front view schematic diagram of an exemplary incense stick holder according to some embodiments of this application is shown; Figure 6 An enlarged structural schematic diagram of an exemplary region A according to some embodiments of this application is shown.

[0053] refer to Figures 4 to 6As shown. The one or more clamping parts 20 are fixedly or detachably connected to the inlet part 10. The clamping parts 20 are arranged obliquely along the direction from the inlet part 10 to the receiving part 30. Each clamping part 20 is provided with at least two clamping free ends 20b extending toward the center of the insertion hole 10a. The clamping free ends 20b are made of a low thermal conductivity elastic material and are used for radial positioning and elastic clamping of the inserted incense stick.

[0054] Specifically, the one or more clamping portions 20 are circumferentially spaced along the insertion hole 10a and apply clamping force to the inserted incense stick from different directions. Each clamping portion 20 is arranged in a manner including, but not limited to, relative, symmetrical, or asymmetrical arrangements. For example, the number of clamping portions 20 can be one, two, three, four, or more, and the clamping free ends 20b of each clamping portion 20 can be two, three, four, or more. For example, when a clamping portion 20 is set as a single clamping portion, its two clamping free ends 20b can be arranged relative to each other and symmetrically arranged at 180 degrees. When there are three or more clamping free ends 20b, each clamping free end 20b can be evenly distributed around the center of the insertion hole 10a and arranged with three clamping points radially offset by 120 degrees, or each clamping free end 20b can be offset along the height direction of the inlet portion 10 to improve the adaptability to incense sticks of different diameters.

[0055] Each clamping part 20 can have the same number and style of clamping free ends 20b, or it can have different numbers and styles of clamping free ends 20b, depending on the actual needs and cost of the operator. Each clamping part 20 includes a clamping fixed end 20a and a clamping free end 20b. The clamping fixed end 20a is connected to the inlet part 10, and the clamping free end 20b extends toward the center of the insertion hole 10a and at least partially extends into the extension area of ​​the insertion hole 10a, so as to form a clamping space 21 for the incense stick to pass through inside the insertion hole 10a. The clamping free end 20b forms point contact or partial line contact with the incense stick. By reducing the contact area between the clamping free end 20b and the incense stick, the heat conduction of the clamping part 20 to the incense stick is reduced, and the impact on the air circulation in the incense stick combustion area is reduced, so as to maintain the continuous smoldering of the incense stick.

[0056] The minimum size of the clamping space 21 is smaller than the maximum outer diameter of the incense stick to be clamped, while the maximum size of the clamping space 21 is larger than the minimum outer diameter of the incense stick to be clamped, so that the clamping part 20 can adapt to the insertion requirements of incense sticks of different specifications within the elastic deformation range, thereby realizing the self-centering positioning of the incense stick.

[0057] In some examples of this application, the clamping part 20 is made of a flexible metal material, polymer material or composite material, including but not limited to elastic metal material; in this application, spring steel, stainless steel, titanium alloy, nickel titanium alloy, copper alloy, polyimide, polyether ether ketone or a combination of the above materials are exemplary. The clamping free end 20b is preferably made of a material with low thermal conductivity and high temperature resistance to reduce the absorption of heat from the burning incense stick.

[0058] Therefore, the clamping free end 20b can undergo elastic deformation due to the pressure of the outer wall of the incense stick during insertion and open in a direction away from the center of the socket 10a; after the incense stick reaches the predetermined insertion position, the clamping free end 20b provides a rebound force towards the center of the socket 10a under its own restoring force, thereby clamping and positioning the incense stick from multiple directions; since the clamping free end 20b has elastic deformation capability, it can be adapted to incense sticks of different diameters without changing the size of the socket 10a to achieve positioning.

[0059] In some examples of this application, the clamping free end 20b is in the form of, but not limited to, barbed, hooked, or straight needle.

[0060] Specifically, when the clamping free end 20b adopts a barbed structure, it improves the limiting ability of the incense stick; when the clamping free end 20b adopts a bent hook structure, it can form a certain guiding effect when clamping the incense stick; when the clamping free end 20b adopts a straight needle structure, its free end forms a pointed part, which contacts the outer surface of the incense stick. Those skilled in the art should understand that any structure that can form point contact or partial line contact and provide elastic clamping effect can be used as the clamping free end 20b.

[0061] In some examples of this application, the clamping part 20 may be a one-piece molded structure, for example, formed by stamping, wire cutting, laser cutting, metal injection molding or additive manufacturing processes; or it may be formed by assembling independent parts and connected to the inlet part 10 by welding, snap-fitting, riveting, bonding or threaded connection.

[0062] During the use of incense sticks, after the incense stick is inserted from the top of the insertion hole 10a, the clamping free end 20b opens outward when squeezed by the outer wall of the incense stick and provides a rebound force to clamp the incense stick after it reaches the predetermined position. Since the clamping free end 20b maintains partial contact with the incense stick and the clamping part 20 is suspended in the air, the heat generated during the burning of the incense stick can be gradually transferred to the clamping free end 20b through thermal radiation and thermal convection, causing the temperature of the clamping free end 20b to gradually rise. When the incense stick is burning close to the clamping position, the clamping free end 20b will not absorb a large amount of heat, thus preventing the temperature of the incense burning area from dropping, which is conducive to maintaining the continuous smoldering of the incense stick.

[0063] refer to Figure 6 As shown. In some embodiments of this application, the multiple clamping parts 20 can be arranged on the same horizontal plane or staggered along the height direction of the inlet part 10; and the multiple clamping free ends 20b can be symmetrically arranged around the circumference of the insertion hole 10a or staggered around the circumference of the insertion hole 10a, so as to adapt to the clamping requirements of different specifications of incense sticks.

[0064] Specifically, when multiple clamping free ends 20b are arranged on the same horizontal plane, the multiple clamping free ends 20b act together on the same axial position of the incense stick and are symmetrically arranged along the circumference of the insertion hole 10a to achieve radial positioning of the incense stick and symmetrically clamp the incense stick at the same height; wherein, when multiple clamping free ends 20b are symmetrically clamped by two free ends, the incense stick is radially clamped by multiple clamping free ends 20b and the bottom end of the incense stick is supported by the receiving part 30, thereby preventing the incense stick from sliding axially or tipping over, so as to keep the incense stick in a basically vertical insertion state.

[0065] Specifically, when multiple clamping free ends 20b are staggered along the height direction of the inlet 10, the contact positions between different clamping free ends 20b and the incense stick are distributed at intervals along the axial direction of the incense stick and arranged at intervals along the circumferential direction of the insertion hole 10a, forming a multi-point clamping positioning; wherein multiple clamping free ends 20b can be three, four or more clamping free ends staggered along the axial and circumferential directions of the incense stick to clamp and position the incense stick from different directions, thereby improving the adaptive clamping capability for fine-gauge incense sticks, high-oil incense sticks and incense sticks of different diameters.

[0066] It is understandable that when incense sticks are made of particularly fine dimensions or materials with a high oil content, if multiple clamping free ends 20b are symmetrically clamped only along the same axial position of the incense stick, the contact area between the multiple clamping free ends 20b and the incense stick is likely to be concentrated at the same burning position of the incense stick, which may affect the air circulation and heat transfer in the burning area of ​​the incense stick. Therefore, this application can adopt multiple clamping free ends 20b that are staggered along the axial direction of the incense stick and circumferentially staggered around the insertion hole 10a, so that the multiple clamping free ends 20b act on different burning positions of the incense stick, thereby reducing heat conduction while ensuring stable clamping, so that the incense stick can continue to smolder.

[0067] Figure 7 A schematic diagram of a second style of an exemplary incense stick holder according to some embodiments of this application is shown; Figure 8 A second-style front view of an exemplary incense stick holder according to some embodiments of this application is shown. (Reference) Figure 7 and Figure 8As shown in some examples of this application, this application employs three clamping portions 20 arranged in a staggered manner along the same axial position of the incense stick. The angle between the free ends 20b of each of the three clamping portions 20 is exemplarily 120°, and an axial clamping space 21 is formed between the free ends 20b of the three clamping portions 20 to clamp incense sticks of particularly fine specifications or with a high oil content.

[0068] As the incense stick continues to smolder and gradually burns downwards, the contact between the upper clamping free end 20b and the incense stick will be released first, while the lower clamping free end 20b continues to provide clamping effect; when the incense stick burns further to the lower clamping free end 20b, the lower clamping free end 20b also returns to its initial position, thereby causing the remaining incense stick to lose its clamping constraint and fall downwards into the receiving part 30 to continue burning.

[0069] refer to Figure 6 As shown. In some examples of this application, when multiple clamping parts 20 are misaligned along the height direction, the multiple clamping parts 20 include at least a first clamping part 22 and a second clamping part 23. The first clamping part 22 includes at least two first clamping members arranged symmetrically with each other, and the second clamping part 23 includes at least two second clamping members arranged symmetrically with each other.

[0070] The first clamping part 22 is inverted and disposed inside the inlet part 10 and is provided with one or more first clamping free ends 20b. The first clamping free ends 20b are inclined along the direction from the inlet part 10 to the receiving part 30 and extend toward the center of the socket 10a, at least partially extending into the extension area of ​​the socket 10a. The second clamping part 23 is inverted and disposed inside the inlet part 10 and is provided with one or more second clamping free ends 20b. The second clamping free ends 20b are inclined along the direction from the inlet part 10 to the receiving part 30 and extend toward the center of the socket 10a, at least partially extending into the extension area of ​​the socket 10a. The second clamping free ends 20b are lower than the first clamping free ends 20b in the height direction.

[0071] The at least two first clamping members are inverted and disposed within the inlet portion 10, with the first clamping free ends 20b of the at least two first clamping members located on the same horizontal plane to form a first clamping space 21a; the at least two second clamping members are inverted and disposed within the inlet portion 10, with the second clamping free ends 20b of the at least two first clamping members located on the same horizontal plane to form a second clamping space 21b; wherein the second clamping space 21b is lower than the first clamping space 21a in the height direction, and the central axes of the first clamping space 21a and the second clamping space 21b are substantially coincident, so that the incense stick can pass through the first clamping space 21a and the second clamping space 21b in sequence during the insertion process and ultimately maintain a state substantially consistent with the axis of the insertion hole 10a.

[0072] refer to Figure 6 As shown. Exemplarily, in this application, the first clamping part 22 includes a first clamping member I22a and a first clamping member II22b. The first clamping member I22a is provided with a first clamping free end I, and the first clamping member II22b is provided with a first clamping free end II. The second clamping part 23 includes a second clamping member I23a and a second clamping member II23b. The second clamping member I24a is provided with a second clamping free end I, and the second clamping member II23b is provided with a second clamping free end II.

[0073] The first clamping space 21a and the second clamping space 21b may have the same or different dimensions. For example, the first clamping space 21a may be slightly larger than the second clamping space 21b so that the incense stick can be initially guided when inserted, while the second clamping space 21b is used to position and clamp the incense stick. Alternatively, the first clamping space 21a and the second clamping space 21b may have the same size to achieve uniform clamping.

[0074] In some examples of this application, the first clamping free end 20b and the second clamping free end 20b are offset along the incense stick axis, so that there is no completely overlapping contact area between the clamping free ends 20b, thereby reducing the heat conduction of the clamping part 20 to the incense stick and avoiding multiple clamping free ends 20b acting on the same combustion position, which would affect air circulation.

[0075] It is understood that the use of two sets of clamping parts 20 staggered along the height direction in this application is only an example implementation. In other embodiments, three, four or more sets of clamping parts 20 may be set and arranged sequentially along the height direction of the inlet part 10. As long as the purpose of graded clamping, stable positioning and gradual release of the remaining incense root during the burning process can be achieved, they should be regarded as equivalent replacements of this application.

[0076] It is understood that the description of the number, shape, arrangement, material and manufacturing process of the clamping part 20 in this application is only an example. Those skilled in the art can make equivalent substitutions or combinations without departing from the concept of this application. Any structure that can achieve elastic clamping, adaptive positioning and reduced heat conduction of the incense stick should be regarded as an equivalent embodiment of this application.

[0077] refer to Figures 2 to 6 As shown. In some embodiments of this application, the one or more clamping portions 20 further include one or more limiting members 24, which may be integrally formed with the clamping portion 20 or fixed to the clamping portion 20 as independent components.

[0078] Specifically, the one or more limiting members 24 are respectively connected to the corresponding clamping part 20 and are arranged circumferentially along the insertion hole 10a. Each limiting member 24 includes a limiting fixed end 24a and at least one limiting free end 24b. The limiting fixed end 24a is used to connect with the clamping part 20, and the limiting free end 24b is arranged obliquely along the direction from the inlet part 10 to the receiving part 30 and extends toward the center of the insertion hole 10a, at least partially extending into the extension area of ​​the insertion hole 10a.

[0079] In some examples of this application, the limiting member 24 may be disposed on any one or more of the first clamping portion 22, the second clamping portion 23, or a plurality of clamping portions 20; for example, the limiting member 24 may be disposed on the clamping portion 20 at a higher position along the height direction to provide guidance and limiting function in the initial stage of incense insertion; or disposed on the clamping portion 20 at a lower position along the height direction to provide auxiliary support for the remaining incense root in the later stage of incense burning; or disposed in an array at any position of the clamping portion 20 along the height direction.

[0080] Each limiting member 24 may also be provided with two or more limiting free ends 24b. The multiple limiting free ends 24b may be located on the same horizontal plane and evenly distributed around the circumference of the socket 10a, or they may be staggered along the height direction to form a limiting space around the center of the socket 10a, so that the incense stick can be limited when it is tilted in any direction. For example, when the incense stick is subjected to an external collision or swings due to its own center of gravity shift, the outer surface of the incense stick will first contact the limiting free end 24b in the corresponding direction and return to a position close to the center of the socket 10a under the blocking action of the limiting free end 24b. The maximum size of the limiting space is greater than or equal to the maximum size of the clamping space 21 and less than the maximum inner diameter of the socket 10a.

[0081] In some examples of this application, the limiting free end 24b adopts a structure including but not limited to straight rod, arc, needle, bent or other structure that can form a local limiting effect, and the end of the limiting free end 24b includes but is not limited to rounded corners, spherical surface, chamfer or passivation treatment, so as to avoid damaging the surface of the incense stick or affecting the normal smoldering of the incense stick when it comes into contact with the incense stick.

[0082] In some examples of this application, the limiting member 24 and the clamping part 20 may be made of the same material, or they may be made of a material with a lower elastic modulus than the clamping part 20, so as to reduce the force generated when the limiting member 24 comes into contact with the incense stick.

[0083] Specifically, the limiting free end 24b maintains a non-contact state or forms an intermittent contact state with the incense stick. In other words, when the incense stick is in the normal insertion state, a preset gap can be maintained between the limiting free end 24b and the incense stick; when the incense stick is deflected due to external force, the limiting free end 24b can contact the incense stick and form a limiting effect on it, thereby limiting the extent to which the incense stick deviates from the axis of the socket 10a.

[0084] It is understood that the number, arrangement, structure and material selection of the limiting member 24 in this application can be adjusted according to actual needs; for example, two, three, four or more limiting members 24 can be set, or a multi-layer limiting structure or a staggered arrangement along the height direction can be adopted. As long as the structure can limit the deflection of the incense stick and does not affect the continuous smoldering of the incense stick, it should be regarded as an equivalent implementation of this application.

[0085] <Containment Section 30> Figure 9 An enlarged structural schematic diagram of an exemplary region B according to some embodiments of this application is shown.

[0086] refer to Figures 1 to 5 , Figure 9 As shown. The receiving part 30 is disposed below the insertion hole 10a and communicates with the communication port 12 of the insertion hole 10a. It is used to receive and support the remaining incense stick when the incense stick burns down to below the clamping free end 20b, so that the remaining incense stick can continue to smolder until it is completely burned.

[0087] The receiving portion 30 is made of materials including but not limited to metal, ceramic, polymer or composite materials. For example, in this application, the receiving portion 30 is made of the same material as the clamping portion 20 to reduce the transfer of combustion heat to the receiving portion 30.

[0088] The receiving portion 30 forms a receiving space 30a that is at least partially hollowed out. The receiving space 30a is used to accommodate the remaining incense root after the incense stick has burned and to provide an air circulation channel for the burning area. The axial dimension of the receiving space 30a along the insertion hole 10a is greater than the maximum length of the incense root. For example, when the length reserved at the end of the incense stick is 5mm to 20mm, the axial dimension of the receiving space 30a can be set to 6mm to 25mm to ensure that the remaining incense root can be completely accommodated in the receiving space 30a. Those skilled in the art should understand that the above size range is only an example and does not constitute a limitation on the scope of protection of this application.

[0089] Furthermore, the contact area between the accommodating space 30a and the remaining incense stick is smaller than the projected area of ​​the bottom of the socket 10a. At least a portion of the accommodating space 30a and the socket 10a together form an airflow space, allowing external air to enter the combustion zone through the gap between the side wall of the socket 10a, the accommodating space 30a, and the first connector 31.

[0090] In some examples of this application, the receiving portion 30 includes at least two first connectors 31 and one or more contact points 32 evenly distributed on the at least two first connectors 31. The at least two first connectors 31 together form a support frame for the receiving space 30a and provide support for the remaining incense sticks located in the receiving space 30a.

[0091] Specifically, the at least two first connectors 31 extend along the insertion direction of the socket 10a and are connected to each other at the end away from the socket 10a to form a receiving space 30a with a preset size; wherein the receiving space 30a can be formed in a planar shape, or in a concave shape, an arc shape or other spatial structure suitable for receiving the remaining incense sticks.

[0092] In some examples of this application, the first connector 31 has an arc-shaped structure and is arranged circumferentially along the central axis of the insertion hole 10a; in other examples, the first connector 31 may also adopt a shape including but not limited to a straight line, a broken line, a wave, a grid, a hollow mesh structure or other shapes that can form a support structure.

[0093] The number of the first connectors 31 is two, three, four or more. When there are two first connectors 31, the two first connectors 31 can be arranged opposite each other to form an open accommodating space 30a. When there are three or more first connectors 31, each first connector 31 can be evenly distributed around the center of the socket 10a.

[0094] In other examples of this application, the receiving part 30 may also adopt a multi-slit point support structure, a multi-needle support structure, a porous high-temperature resistant support structure, or a low thermal conductivity curved surface support structure; for example, the receiving part 30 may adopt a dot matrix support surface formed by multiple contact points, or a net-like support structure formed by multiple needle-like structures, or a receiving surface formed by high-temperature fireproof cotton with a porous structure, high-temperature resistant ceramic fiber material, or other high-temperature resistant materials with low thermal conductivity, so that the remaining incense root can be suspended on the receiving surface and continue to maintain a smoldering state.

[0095] Therefore, regardless of the support form adopted by the receiving part 30, the contact area between it and the remaining incense root is smaller than the projected area of ​​the bottom of the insertion hole 10a, and at least one air circulation channel is formed between the receiving space 30a and the insertion hole 10a, so that external air can enter the area around the remaining incense root to maintain the air circulation conditions required for the continuous smoldering of the remaining incense root.

[0096] During the use of incense sticks, when the incense sticks burn down to below the free end 20b, the remaining incense sticks fall into the receiving space 30a under their own gravity and are supported by the receiving part 30. Since the receiving part 30 adopts at least a partially hollow structure or a low thermal conductivity receiving structure to prevent the remaining incense sticks from falling into gaps, depressions or pores, the remaining incense sticks can continue to smolder in a free receiving state and gradually burn until they are basically burned out.

[0097] It is understood that the use of the first connector 31 to form a net-like accommodating space 30a in this application is only a preferred embodiment. In other embodiments, a planar support structure (such as an incense tray or incense holder), a curved support structure, a porous support structure, a multi-point support structure, or other structural forms that can freely support the remaining incense roots and prevent them from getting stuck can also be used. Any structure that can freely support the remaining incense roots, reduce heat conduction, and prevent the remaining incense roots from falling and getting stuck, thus affecting their continued combustion, should be regarded as an equivalent replacement for this application.

[0098] The multiple first connectors 31 can be connected by integral molding, or a second connector 33 can be provided between the multiple first connectors 31 for connection. The second connector 33 includes, but is not limited to, connecting wires, connecting rings, connecting plates or other connecting structures to prevent the remaining incense sticks from leaving the accommodating space 30a during the burning process. In this application, the second connector 33 is exemplarily adopted as a filament structure, and its cross-sectional size is less than or equal to the cross-sectional size of the first connector 31.

[0099] Specifically, the contact point 32 is located on the side of the first connector 31 facing the accommodating space 30a and at least partially protrudes from the surface of the first connector 31. The contact points 32 are arranged at intervals along the length of the first connector 31, so that the contact points 32 form point contact or partial line contact with the remaining incense root, thereby reducing the contact area between the remaining incense root and the accommodating part 30. Since the contact area is small, the absorption of the remaining incense root's combustion heat by the accommodating part 30 can be reduced, while facilitating the entry of air into the area around the remaining incense root to maintain the continuous smoldering of the remaining incense root.

[0100] The contact point 32 may be a protrusion, boss, short line segment, needle-like structure, spherical structure, prism structure or other structure that can form a local support function, and the number of contact points 32 may be one or more. Multiple contact points 32 may be evenly distributed at equal intervals or unevenly distributed.

[0101] In some examples of this application, the accommodating part 30 can adopt an open structure as a whole, that is, multiple through openings are formed between the first connecting members 31, so that the remaining incense sticks can simultaneously obtain air supply from the radial and axial directions during the burning process; the accommodating part 30 can also adopt a mesh structure, grid structure or frame structure to further improve air circulation efficiency.

[0102] It is understood that the descriptions of the number, shape, connection method, arrangement of contact points 32, size, material and manufacturing process of the accommodating part 30, the accommodating space 30a and the manufacturing process in this application are merely examples. Those skilled in the art can make equivalent substitutions or combinations without departing from the concept of this application. Any structure that can receive the remaining incense root, reduce the contact area and maintain the remaining incense root in a continuous smoldering until it is completely burned should be regarded as an equivalent implementation of this application.

[0103] In some embodiments of this application, at least two clamping portions 20 and receiving portions 30 have at least a portion of their outer surfaces coated with one or more layers of low thermal conductivity material coating.

[0104] Specifically, the low thermal conductivity material coating can continuously cover the outer surfaces of the clamping part 20 and the receiving part 30, or it can be only applied to the area in contact with the incense stick, a portion near the combustion area, or an area prone to heat accumulation. Those skilled in the art should understand that the coverage area of ​​the low thermal conductivity material coating can be adjusted according to actual usage requirements and is not limited to complete coverage. The low thermal conductivity material coating can be formed by spraying, dipping, electrophoretic deposition, chemical deposition, physical vapor deposition, chemical vapor deposition, plasma spraying, anodizing, or heat treatment. For example, when the clamping part 20 and the receiving part 30 are made of metal, the coating can be formed by anodizing or plasma spraying; when the clamping part 20 and the receiving part 30 are made of polymer material, the coating can be formed by spraying or dipping.

[0105] The thermal conductivity of the low thermal conductivity material coating is lower than that of the substrates of the clamping part 20 and the receiving part 30, so as to reduce the rate at which heat is transferred from the incense stick to the clamping part 20 and the receiving part 30. The low thermal conductivity material coating is formed by means of inorganic coating, organic coating or composite coating, including but not limited to alumina, zirconium oxide, silicon dioxide, silicon nitride, ceramic composite material, polyimide, polytetrafluoroethylene, high temperature resistant resin or combination of the above materials.

[0106] In some examples of this application, the low thermal conductivity material coating adopts a multi-layer composite structure, including a bonding layer in contact with the substrate and an insulating layer disposed on the outside of the bonding layer. The bonding layer is used to improve the adhesion between the coating and the substrate, and the insulating layer is used to reduce heat transfer. In actual implementation, a wear-resistant layer, an anti-oxidation layer or an anti-corrosion layer can also be disposed on the outside of the insulating layer to improve the long-term service life of the clamping part 20 and the receiving part 30.

[0107] It is understood that the material type, number of layers, thickness, coverage area and preparation process of the low thermal conductivity material coating of this application can be adjusted according to actual needs. Any surface treatment method that can reduce the heat conduction of the clamping part 20 and the accommodating part 30 and improve the high temperature resistance should be regarded as an equivalent embodiment of this application.

[0108] refer to Figure 1 and Figure 2 , Figure 4 and Figure 5 As shown. In some embodiments of this application, the incense stick holder 1 further includes a support portion 40.

[0109] The support part 40 is connected to the inlet part 10 and is used to install at least part of the incense stick insertion device 1 into the incense holder of the incense burner.

[0110] Specifically, the support part 40 is disposed below, to the side or around the inlet part 10. In this application, the support part 40 is exemplary disposed below the inlet part 10, and it adopts a columnar structure, plate-like structure, ring-like structure or frame structure, including but not limited to columnar structure, plate-like structure, ring-like structure or frame structure. For example, the support part 40 adopts a cylindrical support column, with its support connection end 41 connected to the inlet part 10 and its support end 42 fixed inside the incense holder.

[0111] The support part 40 is made of materials including but not limited to metal, ceramic, polymer or composite materials, such as stainless steel, aluminum alloy, titanium alloy, copper alloy, alumina ceramic, polyether ether ketone or a combination of the above materials, to meet the usage requirements of the incense stick insertion device 1 during long-term repeated insertion and removal of incense sticks.

[0112] The support part 40 can be integrally formed with the inlet part 10, or it can be a separate component that is detachably or fixedly connected to the inlet part 10. For example, the support part 40 and the inlet part 10 can be connected by means including but not limited to welding, riveting, snap-fitting, threaded connection, press-fitting connection, bonding or embedding.

[0113] The support column can be integrally formed with the inlet part 10, or it can be used as a separate component to be installed with the incense burner. For example, the installation position of the support column and the incense burner may include, but is not limited to, one or more combinations of external threads, internal threads, snaps, plugs, positioning bosses, positioning grooves, magnetic components, or elastic limiting components 24.

[0114] In some examples of this application, for instance, the outer periphery of the support part 40 is provided with an external thread, and the incense holder is provided with a matching internal thread, and the support part 40 is installed in the incense holder by screwing; in another example, the support part 40 may also be provided with an elastic buckle, which is fixed in the incense tray by snap-fit; in another example, the support part 40 may also be provided with a magnetic component, which is detachably connected to the metal parts provided in the incense burner by magnetic attraction.

[0115] In some examples of this application, the support part 40 may also be provided with an adjustment structure to adjust the installation height, tilt angle or installation position of the incense stick insert 1 relative to the incense burner; for example, the support part 40 may adopt a telescopic component, a threaded adjustment component or a spherical universal connection component to adapt to the installation requirements of different types of incense burners.

[0116] In actual use, the support part 40 first completes a fixed connection with the incense burner, and then the inlet part 10, the clamping part 20 and the receiving part 30 work together to insert the incense stick.

[0117] It is understood that the structure, installation method, material type and setting position of the support part 40 of this application can be adjusted according to the structure of different incense burners. As long as the structure can connect the incense stick insertion device 1 with the incense burner and provide support, it should be regarded as an equivalent embodiment of this application.

[0118] Therefore, the usage process of the incense stick holder 1 is as follows: After the incense stick is inserted into the upper end of the socket 10a, it first pushes the first clamping free end 20b to elastically open and is initially positioned by the first clamping part 22 after passing through the first clamping space 21a. Then the incense stick continues to move downward and pushes the second clamping free end 20b to elastically open. After passing through the second clamping space 21b, it is further positioned by the second clamping part 23. Since the first clamping space 21a and the second clamping space 21b are arranged sequentially along the height direction, the self-centering clamping of the incense stick can be achieved, so that incense sticks of different diameters can be kept stable along the axial direction of the socket 10a.

[0119] As the incense stick continues to smolder and gradually burns downwards, the burning area first moves to the first clamping free end 20b. When the incense stick at the position corresponding to the first clamping free end 20b is completely burned out, the first clamping free end 20b loses its support and returns to its initial position under the elastic recovery action, while the second clamping part 23 continues to provide clamping action for the remaining incense stick. Subsequently, the incense stick burns further to the second clamping free end 20b, and the second clamping free end 20b returns to its initial state. At this time, the remaining incense stick loses the clamping constraint in the radial direction and falls into the receiving space 30a of the receiving part 30 under its own gravity and is supported by the contact point 32. Since the contact point 32 and the remaining incense stick form a partial contact, and the receiving part 30 as a whole has at least a partially hollow structure, the remaining incense stick can continuously obtain the air required for combustion and remain in a smoldering state until it is completely burned out.

[0120] Figure 10 A schematic diagram of the additive manufacturing process of an exemplary incense stick insert device according to some embodiments of this application is shown.

[0121] refer to Figure 10 As shown. In one manufacturing embodiment of this application, the incense stick inserting device 1 is processed using additive manufacturing technology to achieve integrated manufacturing of the inlet part 10, the clamping part 20, the accommodating part 30, and the supporting part 40, thereby reducing assembly steps and improving the processing accuracy of complex hollow structures, overhanging structures, and micro-support structures. In the actual additive manufacturing process, the operator can set the incense stick inserting device 1 to be printed upright or upside down according to actual needs.

[0122] For example, the upright additive manufacturing process of the incense stick insert 1 is as follows: A three-dimensional digital model is established based on the design parameters of the incense stick insertion device 1. The three-dimensional digital model includes at least the structural information of the inlet part 10, the clamping part 20, the accommodating part 30 and the supporting part 40, and parametrically models the local fine structures such as the clamping free end 20b, the limiting free end 24b and the contact point 32. Then, the three-dimensional digital model is sliced ​​to generate processing data suitable for additive manufacturing equipment. Depending on the type of material selected, additive manufacturing processes such as selective laser melting (SLM), selective laser sintering (SLS), electron beam melting (EBM) or fused deposition modeling (FDM) can be used.

[0123] In some examples of this application, the incense stick insert 1 is integrally formed using titanium alloy powder through selective laser melting. Since additive manufacturing can realize the manufacturing of complex suspended structures and micro-feature structures, it can directly form the clamping free end 20b, the limiting free end 24b, and the contact point 32 in the receiving part 30 without subsequent assembly.

[0124] After additive manufacturing is completed, the incense stick inserting device 1 undergoes post-processing, including removing the support structure, surface grinding, sandblasting, heat treatment, and dimensional correction, in order to improve the elasticity and overall dimensional accuracy of the clamping part 20.

[0125] In some examples of this application, the clamping part 20 and the receiving part 30 are surface treated, for example, by forming a low thermal conductivity material coating through anodizing, plasma spraying, chemical deposition or physical vapor deposition, so as to further reduce the transfer of the heat of burning incense to the incense inserting device 1.

[0126] In another manufacturing embodiment of this application, the incense stick holder 1 is manufactured using conventional manufacturing methods, specifically as follows: The inlet portion 10, clamping portion 20, accommodating portion 30, and supporting portion 40 of this application are assembled after being processed separately; wherein the inlet portion 10 and supporting portion 40 are formed by processes including but not limited to turning, milling, drilling, stamping, die casting, metal injection molding, or ceramic sintering; the clamping portion 20 is formed by processes including but not limited to wire cutting, laser cutting, stamping, bending, or elastic component processing; and the accommodating portion 30 is formed by processes including but not limited to stamping, welding, precision casting, or machining.

[0127] In some examples of this application, an inlet portion 10 is formed and an insertion hole 10a is formed in the inlet portion 10. Multiple clamping portions 20 and limiting members 24 are formed and fixed inside the inlet portion 10. A receiving portion 30 is formed and connected to the inlet portion 10. A support portion 40 is formed and assembled with the inlet portion 10 to form a complete incense stick insert device 1. The components can be assembled by welding, brazing, riveting, snap-fitting, threaded connection, press-fitting connection, laser welding or bonding.

[0128] After assembly, the incense stick inserting device 1 is subjected to elastic calibration and functional testing. For example, the clamping force of the clamping free end 20b, the size of the clamping space 21, the size of the accommodating space 30a, and the overall installation size are tested to ensure that the incense stick inserting device 1 can be adapted to incense sticks of preset specifications.

[0129] Then, according to actual needs, the surface treatment of the incense stick insert device 1 is carried out, including polishing, sandblasting, oxidation treatment, electroplating treatment, spraying low thermal conductivity material coating or high temperature resistant coating, etc.

[0130] It is understood that the additive manufacturing method and the conventional manufacturing method are only preferred manufacturing methods for the incense stick inserting device 1 of this application. Those skilled in the art can select appropriate manufacturing processes according to material type, production scale and cost requirements, or combine additive manufacturing processes with conventional manufacturing processes. For example, additive manufacturing can be used to form an integrated structure of the inlet part 10, the clamping part 20 and the receiving part 30, and then conventional processing methods can be used to manufacture the support part 40 and assemble it. Any processing technology that can realize the manufacturing of the incense stick inserting device 1 of this application should be regarded as an equivalent embodiment of this application.

[0131] Therefore, this application also relates to an incense burning device, which can be integrally formed with the incense stick insertion device 1 by additive manufacturing, or can be manufactured separately. It includes an incense holder and the incense stick insertion device 1 described in any of the above embodiments located on the incense holder.

[0132] Specifically, the incense holder is used to support the incense stick insertion device 1 and collect the incense ash produced during the burning of the incense stick. It can be in the shape of a plate, bowl, box, column, pedestal or other shape suitable for placing the incense stick insertion device 1. Its material can be metal, ceramic, stone, wood, polymer or composite material.

[0133] In some embodiments of this application, the incense stick inserting device 1 and the incense holder are manufactured in one piece, for example, by using additive manufacturing process to form the incense holder, the inlet part 10, the clamping part 20, the accommodating part 30 and the supporting part 40 in one step, thereby reducing the number of parts, improving the overall structural strength and reducing assembly errors.

[0134] In other embodiments of this application, the incense holder and the incense stick insertion device 1 are manufactured independently and connected by an installation structure, which can be one or more combinations of threaded connection, snap-fit ​​connection, plug-in connection, magnetic connection, press-fit connection or adhesive connection.

[0135] For example, the incense holder is provided with an installation hole, and the incense stick insertion device 1 is inserted into the installation hole through the support part 40; or, the incense holder is provided with a threaded installation position, and the incense stick insertion device 1 is fixed to the incense holder by means of threads; or, the incense holder is provided with a magnetic component, and the incense stick insertion device 1 can be detached and installed by means of magnetic attraction.

[0136] In some embodiments of this application, the incense holder is provided with a receiving cavity, ash collection trough or ash receiving tray for collecting incense ash; the incense stick insertion device 1 described above is located in the middle area of ​​the incense holder so that the incense ash generated during the burning of the incense stick can fall naturally into the incense holder.

[0137] In some embodiments of this application, the incense holder may also be provided with auxiliary functional structures, such as an anti-slip pad, a counterweight, a decorative element, a lighting component, or an aromatherapy auxiliary component, to improve the user experience of the incense burning device.

[0138] In some embodiments of this application, the incense holder may also be provided with an air guiding structure to improve airflow near the incense burning area; for example, the incense holder may be provided with through holes, guide grooves, mesh holes or spaced support ribs so that external air can enter the area around the incense insert device 1 to improve the stability of the incense burning continuously.

[0139] In actual use, after the user inserts the incense stick into the incense stick holder 1, the incense stick completes self-centering and positioning under the action of the clamping part 20, and the remaining incense root is received by the receiving part 30 in the later stage of the incense burning. The incense ash produced during the burning process falls into the incense holder and is collected by the incense holder.

[0140] It is understood that the shape, size, material and installation method of the incense holder of this application can be adjusted according to different application scenarios. For example, the incense holder can be a desktop incense burner, a wall-mounted incense burner, a portable incense burner or a combination incense burner. As long as it is a device that can support the incense stick insertion device 1 of this application and realize the burning of incense sticks, it should be regarded as an equivalent implementation of the incense burner of this application.

[0141] It is understood that the incense stick insert device 1 of this application can be sold and used separately as an independent component, or it can be integrated into the overall incense burning device without affecting the scope of protection of this application.

[0142] Therefore, the physical product reference of the incense stick inserting device 1 of this application is as follows. Figures 11 to 13 As shown, Figure 11 Several physical schematic diagrams of an exemplary incense stick holder according to some embodiments of this application are shown. Figure 12 A single physical schematic diagram of an exemplary incense stick holder according to some embodiments of this application is shown.
