  As described above, some incense burners of the type that burn incense pay attention to producing smoke as well as fragrance, and there is a demand for an incense burner that can enjoy the state in which smoke is emitted.

  One aspect of the present invention is an incense burner having a combustion chamber for burning incense inside. This incense burner further has a discharge port for discharging smoke from the combustion chamber to the outside, and a breathable wall portion in which an opening connected to the combustion chamber is covered with a heat insulating material containing heat-resistant fibers, The internal pressure of the combustion chamber can be varied. In the present specification, the combustion includes burning the incense (musk), that is, burning the incense while emitting red smoke and burning.

  In this incense burner, by changing the internal pressure of the combustion chamber, the amount and speed of smoke emitted from the discharge port can be changed. For this reason, not only the smoke rises from the discharge port, but a smoke lump can be discharged from the discharge port, and if a condition is adjusted, a donut-shaped smoke lump can be discharged.

  One form of changing the internal pressure of the combustion chamber is to make part of the wall of the combustion chamber elastically deformable by a force from the outside. For example, the user can enjoy the fluctuation of the state of the smoke emitted from the discharge port by flicking the side or upper surface of the censer by hand. By changing the internal pressure, outside air enters the combustion chamber from the discharge port. For this reason, depending on conditions such as the size of the discharge port and the width of pressure fluctuation, there is a possibility that sufficient combustion air for burning the incense can be obtained from the discharge port. It is also possible to vary the internal pressure of the censer by a mechanical method.

  If the user tries to change the internal pressure of the combustion chamber manually, it may be impossible to keep hitting the upper and side surfaces of the incense burner while the incense is burning. The simplest way to continue combustion is to ensure a sufficient opening area so that the combustion air enters the combustion chamber sufficiently. However, as the opening area increases, it becomes difficult to change the internal pressure of the combustion chamber, and hitting any part of the incense burner reduces the effect on smoke behavior.

  The incense burner of one embodiment of the present invention has an air-permeable wall portion in which an opening connected to the combustion chamber is covered with a heat insulating material containing heat-resistant fibers. This breathable wall part is mainly constructed of a heat-insulating material containing heat-resistant fibers, so that breathability is obtained, so if the internal pressure of the combustion chamber does not fluctuate significantly, the temperature difference between the combustion chamber and the outside air It functions as an opening that guides outside air into the combustion chamber due to the chimney effect. On the other hand, when the pressure in the combustion chamber is changed by a method such as tapping the upper surface of the incense burner, the heat insulating material becomes a gas flow resistance, and the pressure fluctuation in the chamber hardly leaks to the outside, and the internal pressure in the combustion chamber is likely to fluctuate. For this reason, it is possible to easily change the internal pressure of the combustion chamber by a method such as tapping and affect the behavior of smoke emitted from the discharge port.

  It is desirable that the wall portion for ventilation is at least a part of the bottom wall of the combustion chamber and also serves as a support for placing the incense. The vicinity of the wall portion for ventilation is one of the positions suitable for burning the incense in the incense furnace because the oxygen concentration is high. A suitable heat insulating material is a heat-resistant fiber made of cotton and formed into a mat, for example, a glass fiber mat.

  The incense burner is a detachable resin cover for constituting a part of the wall of the combustion chamber, and preferably has an elastically deformable dish-shaped cover. The internal pressure of the combustion chamber can be varied by hitting the cover. In addition, this cover is provided with a concavo-convex pattern to support a plurality of ring-shaped incense, and as a container (container) for supplying a plurality of incense for burning in the incense burner, an alternative with the incense burner Can supply.

  In FIG. 1, the external appearance of the incense burner of embodiment of this invention is shown. FIG. 2 shows a schematic configuration of the incense burner by a development view. The incense burner 1 includes a hollow body 10 that is pentagonal as a whole. The body 10 is formed of ABS resin and includes a cylindrical combustion chamber 11 inside. The upper part of the combustion chamber 11 is a circular opening 12, and a lower part (bottom) 13 has a plurality of support beams 14 extending radially and an opening between the support beams 14. In addition, leg portions 15 are provided at five locations on the bottom of the body 10 so that the bottom 13 is slightly lifted. A cylindrical shield 20 made of aluminum is inserted into the combustion chamber 11 and constitutes a side wall of the combustion chamber 11. A glass fiber mat 25 is placed on the bottom 13 of the combustion chamber 11 and constitutes a breathable bottom wall 19.

  A cover 30 made of a transparent and thin resin (for example, polyethylene terephthalate) is placed on the upper opening 12 of the combustion chamber 11 to constitute the upper wall 18 of the combustion chamber 11. The cover 30 has a thin (low height) dome shape or dish shape with a circular periphery, and a circular opening 39 is formed in the center. The circular opening 39 is fitted with an aluminum holder 55 having a circular discharge port 56 formed in the center, and constitutes a portion for discharging smoke 5 and fragrance from the combustion chamber 11. On the back surface of the holder 55, a metal fitting 57 for attaching a ring-shaped incense (incense) 50 is attached.

  FIG. 3 is a sectional view showing how the incense 50 is attached to the incense burner 1. Incense 50 is obtained by molding musk incense with sandalwood as a main component so that the outer shape becomes a ring shape having a substantially hexagonal shape. The incense 50 can enjoy the scent as it is, but when it is burned, smoke is generated and the scent spreads around the smoke. When burning the incense 50, the holder 55 is removed from the central opening 39 of the cover 30 constituting the upper wall 18 of the incense burner 1. The incense 50 is attached to the metal fitting 57 on the back surface of the holder 55 and ignited. Thereafter, the holder 55 is inserted into the opening 39 of the cover 30.

  As shown in the sectional view of FIG. 4, the incense 50 is set in a state of being suspended inside the combustion chamber 11 by the holder 55. The combustion air 6 is also supplied from the central discharge port 56 of the holder 55, but is mainly supplied via the glass fiber mat 25 on the bottom wall 20 of the combustion chamber 11. The smoke 5 generated by the burning of the incense 50 fills the combustion chamber 11 and is discharged from the discharge port 56.

  This resin cover 30 is thin and elastic, and is elastically deformed when hit with a finger or the like from above. For this reason, when the force 7 is applied to the cover 30 with a finger or the like from above, the cover 30 is elastically distorted and the internal pressure of the combustion chamber 11 can be changed. Since the cover 30 has a thin dome shape, the cover 30 is easily deformed, and the cover 30 bends by hitting with an appropriate force. Thereafter, the cover 30 returns to its original shape, and the volume of the combustion chamber 11 can be greatly changed. As a result, the internal pressure of the combustion chamber 11 can be varied.

  The glass fiber mat 25 constituting the bottom wall 19 of the combustion chamber 11 is formed by matting glass short fibers having a length of about 50 to 75 mm or cotton entangled with long fibers into a mat shape. Is about 3 to 10 mm. The diameter of the glass fiber is about several μm to several tens of μm and has heat resistance of about 600 ° C. Therefore, the member 25 made of glass fiber in a mat shape has a heat insulating property because it includes a large amount of an air layer. Further, since the glass fiber mat 25 is also a porous member, the glass fiber mat 25 is sufficiently breathable to provide the combustion air 6 in a normal state where the incense 50 is burning in the combustion chamber 11. On the other hand, the size of the individual openings formed by the entanglement of the glass fibers is on the order of μm or 1 mm, and the mat 25 has a complicated structure in which these openings are laminated. For this reason, the glass fiber mat 25 becomes resistant to the air flow associated with the rapid pressure fluctuation.

  Therefore, when the cover 30 is elastically deformed by a method such as tapping, the internal pressure of the combustion chamber 11 increases. For this reason, the smoke 5 filling the inside of the combustion chamber 11 is discharged from the discharge port 56 all at once, and is released as ring-shaped smoke when the conditions are satisfied. Therefore, this incense burner 1 can usually burn the incense 50 inside the combustion chamber 11 and enjoy the scent or enjoy the smoke 5 rising from the aromatic mouth 56. Further, by tapping the cover 30, the mass of the smoke 5 can be released from the aromatic mouth 56, and depending on how to strike, the mass of the smoke 5 can be made into a ring shape, or the state where the ring-shaped smoke is diffused can be enjoyed. .

  In FIG. 5, the different usage of the incense burner 1 is shown with sectional drawing. In this example, the incense 50 is placed on the glass fiber mat 25 of the bottom wall 19 and burned. That is, the bottom wall 19 of the combustion chamber 11 is used as a support for burning the incense 50. Since the bottom wall 19 is breathable, the top of the bottom wall 19 is one of the positions where combustion air can be easily obtained. Moreover, since the glass fiber mat 25 also has heat insulation (heat retention), it is easy to maintain combustion.

  The breathable heat insulating material for constituting the bottom wall 19 of the incense burner 1 is not limited to the glass fiber mat 25. In order to obtain air permeability, a sintered metal or other porous ceramic-based heat insulating material may be used. However, it is desirable that the heat insulating material includes a heat-resistant fiber having a high opening ratio and easy to adjust the thickness. . Examples of heat-resistant fibers include silica (silicon) fibers and carbon fibers in addition to glass fibers. Asbestos fibers have high heat resistance but are considered harmful to health and are not preferred. The heat insulating material may be a non-woven fabric using heat-resistant fibers such as glass fibers or a cloth woven with heat-resistant fibers (for example, glass cloth). These materials are also highly heat-insulating and have a certain degree of air permeability. As shown in FIG. 4, when the incense 50 is burned in a state suspended in the combustion chamber 11, it is one of suitable materials. .

  As shown in FIG. 5, when the incense 50 is placed on the bottom wall 19 and used as a support base, the contact area with the incense 50 is increased as compared with the mat 25 in which a cotton-like one is formed, or There are cases where the burning of the incense 50 cannot be maintained due to a lack of the aperture ratio. In this respect, the glass fiber mat 25 is preferable because it can burn the incense 50 in any case. Glass fibers, silica fibers, and carbon fibers are commercially available in the form of cotton-like mats (glass fiber mats, silica fiber mats, etc.) for forming the breathable wall portion of the incense burner 1 Can be used for Further, when a part of the heat insulating material is melted or discolored by the combustion heat of the incense 50, it is easy to replace the mat made of heat-resistant fibers as the heat insulating material.

  The cover 30 constituting the upper wall 18 of the combustion chamber 11 constitutes a part of the upper wall of the incense burner 1 and is detachable and replaceable. In order to increase the pressure fluctuation in the combustion chamber 11, it is desirable that the cover 30 be elastically deformed relatively large with an appropriate force. For this reason, it is desirable to employ a cover 30 having a small thickness (film or thin plate) made of a resin such as PET. Furthermore, the cover 30 is preferably dome-shaped or dish-shaped. On the other hand, there is a high possibility that the inside of the combustion chamber 11 is deformed or discolored due to heat or smoke in the combustion chamber 11 and the transparency is lost. In such a case, it is preferable to replace the cover 30.

  FIG. 6 shows an example in which six incense 50 are placed on the cover 30. The cover 30 of this example has a pattern 31 formed by unevenness, and has a shape that can be used as a member (container, container) for attaching six ring-shaped incense (incense) 50 to form a unit. That is, the pattern 31 of the cover 30 has a design suitable for mounting a plurality of incense 50 and can be supplied together with the incense 50. For this reason, the cover 30 for replacement | exchange can be supplied with the incense 50. FIG.

  The cover 30 is not limited to the upper part of the combustion chamber 11 but may be attached to the front or side. Moreover, the blower outlet 56 can also be arrange | positioned not only upward but the front or side. Further, the cover 30 may be elastically deformed so that the bottom wall or part of the side wall of the combustion chamber 11 can be elastically deformed instead of changing the internal pressure of the combustion chamber 11. For example, a change in the state in which the smoke 5 is emitted even if the internal pressure of the combustion chamber 11 is changed by forming a part of the wall of the combustion chamber 11 with a rubber plate or the like and vibrating or pulsating the plate with a motor or the like. Can enjoy. Further, the internal pressure of the combustion chamber 11 may be varied by connecting the combustion chamber 11 to a device having a function capable of varying the pressure, such as a piston or a diaphragm.

  In addition, the wall portion for ventilation blocked by the heat insulating material is not limited to the bottom wall 19, and may be a side wall of the combustion chamber 11. However, it is easy to guide fresh air to the combustion chamber 11 by the draft pressure, and the bottom wall 19 of the combustion chamber 11 is made of a breathable heat insulating material because it can be used as an incense support. It is an embodiment.
