[0045] Understandably, cylinder 2 supports the whole censer 100, has the opening 21 to the side of main body 1, base 11 is partially inserted into cylinder 2 inside from opening 21 and is abutted with first step 24, and the spices are placed in base 11 as the inner bag 23 of censer 100 holds spices, and the side wall of base 11 inserted into opening 21 and the inner wall between first step 24 in opening 21 of cylinder 2 form heat insulation gap 13, heat insulation gap 13 forms a heat buffer layer, plays the role of slowing down heat conduction, prevents heat from being directly transmitted to the outer wall of cylinder 2 through contact.

[0046] Specifically, refer to Figure 3 Heat insulation gap 13 is a constant gap formed by the outer wall of base 11 and the inner wall of first step 24, and the space size is related to the width of base 11 and first step 24, and the width is usually between 1-5cm.

[0047] Further, in order to strengthen the heat insulation effect, heat insulation gap 13 can also contain heat insulation material or adopt double gap structure.

[0048] Heat insulation gap 13 is communicated with locking groove 111, forms a heat dissipation channel, helps heat to be dissipated from the inside of censer 100 to the external environment, and reduces the internal temperature of cover 12 and base 11.

[0049] Further, locking groove 111 is arranged at the edge position of the inner wall of base 11 towards cover 12 side and is communicated with the external environment, which helps heat insulation gap 13 to be communicated with the external environment.

[0050] The main body 1 includes a furnace base 11 and a furnace cover 12 detachably connected with the furnace base 11, which undertakes the combustion management and heat control inside the incense burner 100. The furnace base 11 holds incense, and insulates heat from being directly transmitted to the furnace cover 12. The furnace cover 12 closes the upper end of the main body 1, and controls the irregular escape of smoke generated by the combustion of incense.

[0051] Optionally, the furnace base 11 can be provided in a circular ring shape or a multi-edge hollow shape, and has a connecting port on the side facing the furnace cover 12. The furnace cover 12 is adaptively matched with the furnace base 11, and is connected with the furnace base 11 by being embedded into the locking groove 111 of the furnace base 11 through the locking member 121.

[0052] Specifically, the locking groove 111 is a groove on the inner wall of the furnace base 11, and the locking member 121 is a protrusion or a spring-type buckle or pin on the furnace cover 12, which is provided on the side facing the furnace base 11. In order to realize the stability of the connection between the furnace cover 12 and the furnace base 11, two groups of locking members 121 are symmetrically provided on the furnace cover 12, and two groups of locking grooves 111 are adaptively provided and symmetrically arranged with respect to the radial direction of the furnace base 11.

[0053] Further, the furnace base 11 is connected with a limiting member 113 on the side close to the cylinder body 2. The cylinder body 2 is provided with a threaded hole 22, and the incense burner 100 further includes a screw 3. When the main body 1 is connected with the cylinder body 2, the limiting member 113 is placed on the first step 24, and the limiting member 113 is locked between the screw 3 and the first step 24 by rotating the screw 3.

[0054] It can be understood that the screw 3 cooperates with the first step 24 to lock the limiting member 113 in the internal space of the cylinder body 2, so as to ensure the stable connection between the furnace base 11 and the cylinder body 2, and at the same time has a certain adjustability. When necessary, the fastening degree of the screw 3 can be adjusted to conveniently separate the furnace base 11 from the cylinder body 2.

[0055] The first step 24 is an annular step structure on the inner wall of the opening 21 of the cylinder body 2, which provides a physical support surface, so that the furnace base 11 is stably placed on this position, forming a transition interface between the cylinder body 2 and the furnace base 11. One of the surfaces of the first step 24 directly contacts the furnace base 11, preventing the furnace base 11 from being too deep into the cylinder body 2.

[0056] Specifically, the limiting member 113 is placed on the first step 24, and the shape of the limiting member 113 matches the shape of the inner wall of the first step 24. The limiting member 113 is arranged on the end of the furnace base 11 facing the cylinder body 2, and the side wall of the furnace base 11 and the inner wall of the first step 24 form a heat insulation gap 13. At least part of the limiting member 113 is locked in the heat insulation gap 13.

[0057] The opening 21 of the barrel 2 provides a convenient assembly interface for connecting the barrel 2 with the base 11, located at the top of the barrel 2 towards the main body 1, and a first step 24 is formed on the inner side thereof.

[0058] The threaded hole 22 on the barrel 2 cooperates with the screw 3, and the limiting piece 113 can be firmly fixed by rotating the screw 3. Such a locking and limiting structure is simple and convenient to operate, and the fastening force of the screw 3 can be accurately controlled to avoid excessive fastening or loosening.

[0059] Further, the threaded hole 22 is connected to the corresponding heat insulation gap 13, which can avoid damage to the threaded hole 22 caused by high temperature, and is conducive to heat management and optimization of the spatial structure design.

[0060] Further, referring to Figure 4 , the barrel 2 is provided with an inner container 23 which is detachably connected to the barrel 2, and the inner container 23 is hollow and forms a storage space 231.

[0061] Further, the barrel 2 is hollow.

[0062] It can be understood that when the screw is loosened and the base 11 is separated from the barrel 2, the base 11 can be taken out alone and the inner container 23 provided with the storage space 231 is exposed, and the storage space 231 makes full use of the space of the equipment incense burner 100, combines the storage function with the aromatherapy function of the incense burner 100, and improves the utilization rate of the overall space.

[0063] Specifically, the base 11 and the cover 12 can use high-temperature resistant and heat expansion resistant materials, such as aluminum alloy, stainless steel, ceramic or refractory metal, and the barrel 2 can select materials with better heat insulation performance, such as double-layer design or combination of different materials inside and outside, to ensure that the items stored in the storage space 231 are not affected by the temperature of the incense burning.

[0064] Further, the inner container 23 is provided with a connecting piece 232 on the side close to the main body 1, and the connecting piece 232 is placed on the first step 24.

[0065] It can be understood that the connecting piece 232 is placed on the first step 24, which simplifies the installation process of the connecting piece 232, and the first step 24 provides a stable support point to ensure the stable connection between the inner container 23 and the barrel 2, and prevents the connecting piece 232 from being displaced or falling off due to gravity or tilting during use.

[0066] The first step 24 limits the downward or inward displacement of the inner container 23, enhancing the connection stability between the inner container 23 and the barrel 2.

[0067] Further, the support provided by the first step 24 itself, the connecting piece 232 can also be tightly matched with the first step 24 through the screw 3 or other locking modes to enhance the stability of the connection between the inner container 23 and the cylinder 2.

[0068] Further, the inner wall of the furnace base 11 is provided with a second step 112 in the circumferential direction of the furnace base 11, and the second step 112 is spaced from the bottom wall of the furnace base 11 to form the accommodating groove 14.

[0069] Understandably, the accommodating groove 14 is a storage space for placing spices, and the second step 112 adds multiple levels to the inner wall of the furnace base 11, which increases the height of the connection between the furnace cover 12 and the furnace base 11. The second step 112 ensures that there is a certain space between the spices and the bottom wall of the furnace base 11, ensuring that each part of the spices can be in contact with oxygen during combustion, achieving full combustion.

[0070] Specifically, the second step 112 is a ring-shaped protruding structure extending inward from the inner wall of the furnace base 11, and the second step 112 forms a stepped accommodating space in the inner wall of the furnace base 11. The accommodating groove 14 is a ring-shaped groove structure formed between the second step 112 and the bottom wall of the furnace base 11.

[0071] Further, the locking groove 111 includes a first locking groove 1111 arranged on the second step 112 in the circumferential direction of the furnace base 11 and a second locking groove 1112 arranged perpendicular to the radial direction of the furnace base 11. The depth of the first locking groove 1111 and the second locking groove 1112 is equal to or greater than the thickness of the locking piece 121.

[0072] Understandably, the width of the locking piece 121 is matched with the depth of the first locking groove 1111 and the second locking groove 1112. The locking piece 121 first enters the second locking groove 1112 arranged perpendicular to the radial direction of the furnace base 11, then rotates along the first locking groove 1111 arranged in the circumferential direction, and is limited in the first locking groove 1111. The first locking groove 1111 limits the up and down movement of the locking piece 121, and the second locking groove 1112 provides preliminary positioning. Users can easily install or disassemble the furnace base 11 and the furnace cover 12.

[0073] Specifically, the first locking groove 1111 is arranged along the edge of the second step 112, and is a ring-shaped or curved groove structure for accommodating the locking piece 121. The depth of the first locking groove 1111 is greater than or equal to the thickness of the locking piece 121, so that the locking piece 121 can be completely accommodated without displacement up and down. The second locking groove 1112 is a groove perpendicular to the radial direction of the furnace base 11. The second locking groove 1112 is arranged between the edge of the furnace base 11 and the second step 112, and is in communication with the first locking groove 1111. The depth of the second locking groove 1112 is consistent with the thickness of the locking piece 121, so that the locking piece 121 can be accommodated in the second locking groove 1112 to avoid radial displacement.

[0074] Further, the length of the first locking groove 1111 is greater than the length of the second locking groove 1112, and the length of the first locking groove 1111 is greater than the length of the locking piece 121. The first locking groove 1111 is in communication with the second locking groove 1112, and the second locking groove 1112 is in communication with the heat insulation gap 13.

[0075] It can be understood that after the furnace cover 12 is installed in place with the furnace base 11 through the first locking groove 1111 and the second locking groove 1112, the bottom of the furnace cover 12 is placed on the second step 112. The first locking groove 1111 is arranged on the second step 112, and the bottom of the furnace cover 12 can seal and cover the first locking groove 1111, preventing smoke from flowing from the first locking groove 1111 which is long in the circumferential direction of the furnace base 11 to the heat insulation gap 13. The second locking groove 1112 is perpendicular to the radial direction of the furnace base 11, i.e., the second locking groove 1112 is arranged vertically. Due to the thermal expansion effect in the accommodating groove 14, the smoke will flow upward from the second locking groove 1112 and will not enter the heat insulation gap 13.

[0076] Specifically, the first locking groove 1111 and the second locking groove 1112 are in communication, so that the locking piece 121 can smoothly enter the first locking groove 1111 from the second locking groove 1112. The heat insulation gap 13 prevents heat conduction, ensuring that the outside of the furnace cover 12 is relatively cool, and preventing the user from being scalded when moving the furnace cover 12.

[0077] Further, the second step 112 is spaced apart from the bottom wall of the furnace base 11 to form an accommodating groove 14. The furnace cover 12 is hollow and cooperates with the accommodating groove 14 to form a smoke outlet space 15.

[0078] It can be understood that the furnace base 11 and the furnace cover 12 are combined to form a smoke outlet space 15, guiding the smoke formed by the burning of spices to a suitable smoke exhaust channel, avoiding the accumulation or backflow of smoke to the inside of the furnace base 11, and ensuring that the smoke can be discharged more smoothly and quickly.

[0079] Specifically, the furnace cover 12 comprises a first furnace cover 122 and a second furnace cover 123, and the first furnace cover 122 and the second furnace cover 123 are provided with a first exhaust hole 1221 and a second exhaust hole 1231 in the circumferential direction of the first furnace cover 122 and the second furnace cover 123.

[0080] In the first furnace cover 122 and the second furnace cover 123, a plurality of groups of the first exhaust hole 1221 and the second exhaust hole 1231 can be arranged, and the first exhaust hole 1221 and the second exhaust hole 1231 are arranged at different heights and located at the top or side of the first furnace cover 122 and the second furnace cover 123, and the exhaust holes at different heights form a layered smoke exhaust effect, and the exhaust holes at different heights help to better regulate the temperature inside the incense burner 100 and help to dissipate heat and avoid overheating.

[0081] Further, the size of the first exhaust hole 1221 and the second exhaust hole 1231 can be changed, or a curved flow guide space or a flow guide piece can be arranged in the smoke outlet space 15 to change the shape of the smoke outlet and enhance the beauty of the smoke and form a specific landscape.

[0082] Further, referring to Figure 5 , the second furnace cover 123 is a tower structure arranged in layers.

[0083] The tower structure arranged in layers optimizes the flow path of external air and smoke, helps to uniformly distribute airflow, ensures the uniformity of temperature and airflow in the furnace cover 12, enhances the beauty of smoke dissipation, avoids local overheating, and the tower enhances the aesthetic appearance of the incense burner 100 and enhances the user experience.

[0084] Specifically, the second furnace cover 123 comprises a middle cage and a roof to form a tower structure.

[0085] Further, the first furnace cover 122 and the second furnace cover 123 are connected by arranging corresponding clamping protrusions and sockets.

[0086] Specifically, the clamping protrusions are arranged on the middle cage, the sockets are arranged on the first furnace cover 122, the clamping protrusions position the middle cage corresponding to the sockets, the roof is sleeved on the middle cage, the socket is further provided with a first clamping thread hole, and the roof is provided with a second clamping thread hole with the same diameter corresponding to the first clamping thread hole. The screws pass through the second clamping thread hole and the first clamping thread hole in sequence to connect and fix the roof and the first furnace cover 122.

[0087] Alternatively, the first furnace cover 122 and the second furnace cover 123 can also be connected by riveting, buckling or bolt, as long as the stable connection of the first furnace cover 122 and the second furnace cover 123 can be realized, which is not limited in the utility model.

[0088] Further, the bottom of the second furnace cover 123 is provided with a positioning groove 124, which cooperates with a positioning protrusion 125 of the first furnace cover 122 towards the second furnace cover 123.

[0089] It can be understood that the cooperation of the positioning groove 124 and the positioning protrusion 125 ensures that the second furnace cover 123 can be accurately positioned during installation, avoids mispositioning or instability of the furnace cover 12, effectively enhances the sealing between the first furnace cover 122 and the second furnace cover 123, avoids leakage of smoke from the joint, and destroys the appearance and smoke mist modeling of the incense burner 100.
