Description

[Technical Field]

[0001] This utility model relates to a handheld heat-insulated moxibustion jar, belonging to the field of moxibustion tools. [Background Technology]

[0002] Moxibustion is a treatment method that uses the heat generated by heating moxa sticks to stimulate acupoints or specific parts of the body. By stimulating the activity of Qi, it can regulate disordered physiological and biochemical functions of the body, thereby achieving the purpose of preventing and treating diseases. When users perform moxibustion on themselves, they usually use wooden moxibustion jars.

[0003] Currently available wooden moxibustion jars have poor heat insulation, making them easy to burn the user's hands. Additionally, the wooden jar may ignite when in contact with a burning moxibustion stick, posing a safety hazard. [Utility Model Content]

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a handheld heat-insulated moxibustion jar.

Detailed Implementation Methods

[0037] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0038] In the following description, terms such as “inner,” “outer,” “upper,” “lower,” “left,” and “right” that indicate orientation or positional relationship are used only for the convenience of describing the embodiments and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0039] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0040] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0041] Example 1:

[0042] Figures 1 to 4 The illustration shows a first embodiment of this utility model, including a base 1, a wooden can 2, and a top cover 3. The top cover 3 can also be used to fix the moxibustion stick. The can 2 and the top cover 3, as well as the can 2 and the base 1, are detachably connected. The can 2 is surrounded by a handle 21. The handle 21 and the inner cavity wall 22 of the can are an integral structure. A first annular heat insulation groove 23 for heat insulation is provided between the handle 21 and the inner cavity wall 22. The inner side of the inner cavity wall 22 of the can is also provided with a metal barrier ring 24. The inside of the barrier ring 24 is provided with a combustion cavity 4 for accommodating the moxibustion stick.

[0043] With this design, firstly, in this embodiment, a handheld part 21 is provided around the two sides of the can body. A first annular heat-insulating groove 23 is provided between the handheld part 21 and the inner cavity wall 22 of the can body. The air in the first annular heat-insulating groove 23 forms a heat-insulating layer, allowing the first annular heat-insulating groove 23 to provide good heat insulation, preventing the user from directly contacting the high-temperature inner cavity wall 22 of the can body and reducing the possibility of burns. Secondly, a metal barrier ring 24 is also provided inside the inner cavity wall 22 of the can body. The barrier ring 24 has a combustion chamber 4 inside to accommodate the moxibustion stick, preventing… When the moxibustion stick burns in the combustion chamber 4, it directly contacts the wooden inner wall 22 of the can, greatly reducing the probability of the can being ignited and improving safety. Finally, the handle 21 and the inner wall 22 of the can are an integral structure, avoiding the problem of glue or other adhesives coming unglued in high-temperature environments. Even when other connection structures are used, the connection structure is prone to deformation in high-temperature environments, leading to connection problems. At the same time, the integral structure is more convenient to process and assemble, reducing the manufacturer's production costs.

[0044] It should be noted that in this embodiment, only a single tank 2 is provided, while in other embodiments, the tank 2 may include multiple detachably connected tank units 20. Such implementation will be described in detail in Embodiment 2.

[0045] The side wall of the canister 2 is provided with a first vent 25. The external space of the canister 2, the first annular heat insulation groove 23, and the combustion chamber 4 are connected through the first vent 25. When the moxibustion stick burns in the combustion chamber 4, it generates moxibustion heat. Part of the moxibustion heat is evenly transferred to the first annular heat insulation groove 23 through the first vent 25 and then to the outer wall of the canister 2 through the first annular heat insulation groove 23. Part of the moxibustion heat is directly transferred to the outside of the canister 2 through the first vent 25, so that the user can perform moxibustion from various angles on the side of the canister 2, expanding the ways of using the product and making it easier for the user to use it freely.

[0046] The base 2 has an inner cavity, and a second annular heat insulation groove 13 is provided on the periphery of the inner cavity. This design allows the base 1 and the jar 2 to have good heat insulation effects, preventing users from being burned by the base 2 of the moxibustion jar when holding it.

[0047] The first annular heat insulation groove 23 is located at the bottom of the tank body 2 with its opening facing downwards, and the second annular heat insulation groove 13 is located at the top of the base 2 with its opening facing upwards. The first annular heat insulation groove 23 and the second annular heat insulation groove 13 are connected to each other, so that the airflow between the base and the tank body can be relatively evenly distributed and will not be too concentrated.

[0048] To facilitate the dissipation of heat, the side wall of the base 1 is provided with a third vent 14, which penetrates the inner wall 12 of the base. The barrier ring 24 is provided with a second vent channel. When the canister 2 and the base 1 are connected, the barrier ring 24 is at least partially embedded in the base 1. The external space of the canister 2 and the combustion chamber 4 are connected through the first vent 25 and the second vent channel. In this way, the heat will not be blocked by the barrier ring 24, allowing the product to dissipate heat smoothly while ensuring safety and heat insulation.

[0049] It should be noted that in this embodiment, the bottom of the barrier ring 24 is provided with a second vent 26 that cooperates with the first vent 25. The second vent 26 constitutes a second vent channel. In other embodiments, the implementation of the second vent channel can also be changed. For example, the length of the barrier ring 24 can be directly changed, and the bottom of the barrier ring 24 can be set above the first vent 25 to avoid it. Such an implementation also falls within the protection scope of this utility model.

[0050] To increase the assembly freedom between the components in this embodiment, at least one of the base 1 and tank 2 components, and the tank 2 and top cover 3 components, are connected by a connecting member. In this embodiment, the base 1 and tank 2 components, and the tank 2 and top cover 3 components are all assembled and connected using the same connecting member. The connecting member includes a first connecting member 5 and a second connecting member 6. The first connecting member 5 includes an extension ring 51 located on one of the components. The second connecting member 6 is located on the inner wall of the other component. The extension ring 51 is embedded in the inner wall of the other component and forms a ventilation gap with respect to the end face of the inner wall. An air outlet is provided at the ventilation gap to communicate with the outside. When the air outlet is located on the tank, the air outlet is a first air outlet 25 located on the tank. When the air outlet is located on the base, the air outlet is a third air outlet 14 located on the base. Referring to the accompanying drawings, taking the first connecting member 5 on the canister 2 and the second connecting member 6 on the base 1 as examples, when the canister 2 and the base 1 are connected, the extension ring 51 is embedded in the inner wall 12 of the base, and a ventilation gap L1 is formed between the end face of the extension ring 51 and the inner wall 12. A third vent 14 communicating with the outside is provided at the ventilation gap L1. In this way, the third vent 14 will not be blocked when the canister 2 and the base 1 are assembled, allowing the heat energy to be released smoothly. Similarly, this connection method can also be set when the top cover 3 is connected to the canister 2, which will not be described in detail in this specification.

[0051] Considering that a barrier ring 24 is also provided in this embodiment, when the top cover 3 and the can body 2 are connected, the extension ring 51 is set at the bottom of the top cover 2, and the ventilation gap is set between the top of the barrier ring 24 and the extension ring 51. This setting is to avoid the barrier ring 24 blocking the air outlet, and also to ensure that the heat of moxibustion can be released smoothly.

[0052] The inner wall 22 of the tank has a radially protruding annular inner groove 29 at the ventilation spacing L1. The first vent 25 is connected to the annular inner groove 29. The annular inner groove 29 is connected to the first annular heat insulation groove 23. The annular inner groove 29 can guide the heat to accumulate in the annular inner groove 29 and be transmitted to the first annular heat insulation groove 23 or directly to the external space through the first vent 25. This allows the gas to be discharged more evenly from the first vent 25.

[0053] In this embodiment, the base 1, the can 2, and the top cover 3 are made of wood. Using wood for the base 1, the can 2, and the top cover 3 is more aesthetically pleasing. Compared to plastic or other materials, wood does not emit harmful substances under high temperature conditions, making it healthier. However, in other embodiments, the base 1, the can 2, and the top cover 3 can also be made of other materials. The first connecting member 5 and the second connecting member 6 are both metal parts, which can withstand high temperatures and protect the wooden base 1, the can 2, and the top cover 3.

[0054] In this embodiment, the second connecting member 6 includes an internal thread, and the extension ring 51 has an external thread that mates with the internal thread. Using a threaded connection ensures good stability and facilitates assembly and disassembly. In other embodiments, other connection methods can be used, such as snap-fit ​​connections. In this embodiment, both the first and second connecting members are metal rings. One metal ring has an internal thread, and the other metal ring is fitted onto the extension ring and has an external thread on its outer wall. The threads of metal parts are less prone to deformation at high temperatures, while the threads of wooden parts are prone to deformation under long-term high-temperature environments, leading to difficulties in later assembly and disassembly.

[0055] It should also be noted that the first and second connecting components in this embodiment are connected by threads, which also has the function of fine-tuning the temperature of the moxibustion jar. Since the moxibustion jar relies on the air outlet channel at the bottom of the base 1 as the main treatment method in most physiotherapy situations, the moxibustion stick is fixed on the top cover 3. In this embodiment, the vertical distance between the components can be adjusted appropriately by the threaded connection between the components, thereby adjusting the distance between the moxibustion stick and the base 1. This can achieve the effect of fine-tuning the temperature of the air outlet channel of the base.

[0056] To increase the limiting effect on the barrier ring, the barrier ring 24 is provided with an outer flange 28, and the inner wall of the tank body 2 is provided with a stepped surface 27. In this embodiment, the lower section of the annular inner groove 29 forms the stepped surface, and the outer flange 28 of the barrier ring 24 abuts against the stepped surface 27, thereby limiting the barrier ring 24 in the lower direction, which facilitates the installation and removal of the barrier ring and makes it convenient for users to clean the ash inside the tank.

[0057] After the tank body 2 is connected to the top cover 3, the top cover 3 is embedded in the tank body 2. The bottom of the top cover 3 forms an upper limit on the barrier ring 24. In this way, the barrier ring 24 is limited both above and below. When the user uses the product, the barrier ring 24 cannot move at will, which prevents the barrier ring 24 from falling off and reduces abnormal noise from the product.

[0058] To ensure the heat insulation effect, the thickness of the first annular heat insulation groove 23 is 1 to 5 mm. If the thickness of the first annular heat insulation groove 23 is less than 1 mm, the heat insulation effect may be poor. If the thickness of the first annular heat insulation groove 23 is greater than 1 mm, the overall strength of the product may be lower, making it easy to be damaged, and the material waste rate may be higher, resulting in higher costs or larger overall product volume.

[0059] The base 1 is provided with an air outlet channel 11 that communicates with the combustion chamber 4. The air outlet channel 11 is provided with a dustproof net 12. When the user performs moxibustion, he / she can align the base 1 of the moxibustion jar with the area to be treated. The heat of the moxa is delivered through the air outlet channel 11. The dustproof net 12 can prevent the ash from falling onto the user and prevent the user from being burned.

[0060] The top cover 3 of the moxibustion jar is also provided with a pin 31 for fixing the moxibustion stick. When the user uses it, the pin 31 is inserted into the moxibustion stick to fix the moxibustion stick and make it less likely to shake.

[0061] The top cover 3 also includes a top cover outer frame 31 and a top cover inner column 32. The top cover outer frame 31 and the top cover inner column 32 are detachably connected. When the top cover inner column 32 is not needed, the top cover inner column 32 can be disassembled, and the moxibustion stick can extend out from the inner cavity of the top cover outer frame 31, so that the heat energy of moxibustion can be directly emitted.

[0062] Example 2:

[0063] like Figure 5 As shown, unlike Embodiment 1, the canister 2 in this embodiment includes three detachably connected canister units 20. In other embodiments, the number of canister units 20 is not limited and can be stacked freely. When more canister units 20 are stacked, it can be used as a moxibustion pillow. Such implementation methods all fall within the protection scope of this utility model.

[0064] In this embodiment, a first connecting member 5 is provided below the top cover 1 and the tank unit 20. The first connecting member 5 is provided with an extension ring 51. A second connecting member 6 is provided above the base 3 and the tank unit 20. When the first connecting member 5 and the second connecting member 6 are connected, the extension ring 51 is embedded inside the second connecting member 6 to realize a detachable connection between the top cover 1 and the tank unit 20, between adjacent tank units 20, and between the tank unit and the base 3. In other embodiments, the positions of the first connecting member and the second connecting member can also be interchanged. This implementation also falls within the protection scope of this utility model.

[0065] It should be noted that in this embodiment, the same connecting components are used to connect the tank units 20, the tank unit 20 and the top cover 3, and the tank unit 20 and the base 1. This makes the connecting components universal in this product. On the one hand, this universal structure reduces the manufacturer's production cost. On the other hand, it allows users to have greater freedom in assembly and can arbitrarily combine and apply them according to their own needs, similar to assembling building blocks.

[0066] In this embodiment, when adjacent tank units 20 are connected, the bottom of the barrier ring 24 of the upper tank unit 20 is inserted into the lower tank unit 20. The barrier ring 24 is provided with a second gas outlet channel. The external space of the tank and the combustion chamber are connected through the first gas outlet hole 25 and the second gas outlet channel.

[0067] It should be noted that in this embodiment, the bottom of the barrier ring 24 is provided with a second vent 26 that cooperates with the first vent 25. The second vent 26 constitutes a second venting channel. In other embodiments, the length of the barrier ring 24 can be changed, and the bottom of the barrier ring 24 can be set above the first vent 25 to avoid it. Such implementation also falls within the protection scope of this utility model.

[0068] like Figure 5 As shown, in this embodiment, the two components of adjacent tank units 20 are connected by the connecting member. One end of the same tank unit 20 is provided with a first connecting member 5, and the other end is provided with a second connecting member 6. The ventilation gap L1 is located between the first connecting member and the second connecting member.

[0069] When the adjacent canister units 20 are connected, the bottom of the barrier ring 24 of the upper canister unit 20 is inserted into the lower canister unit 20 to limit the top of the barrier ring in the lower canister unit 20. In this embodiment, the bottom of the upper barrier ring 24 and the top of the lower barrier ring 24 abut against each other, which can reduce product noise and further prevent the burning moxibustion stick from hitting the wooden canister. In other embodiments, there may also be a certain gap between the bottom of the upper barrier ring 24 and the top of the lower barrier ring 24 to form a second air outlet channel, which is conducive to the dissipation of moxibustion heat. However, the gap is small and can still play a certain limiting role.

[0070] It should be noted that the setting of the first vent for the tank unit 20 can be relatively free. For example, in this embodiment, one of the tank units 20 may not have a first vent, and the implementation method can vary relatively freely.

[0071] To allow for greater flexibility in fixing the moxibustion stick, this embodiment preferably uses a separator plate. The separator plate is positioned between two adjacent canister units 20, and it has pins for fixing the moxibustion stick. When in use, the pins 31 are inserted into the moxibustion stick to fix it in place and prevent it from shaking. Since the separator plate can be positioned between any two adjacent canister units, for moxibustion sticks of different lengths, the separator plate can be installed between the required two adjacent canister units according to actual needs.

[0072] Example 3:

[0073] Unlike Embodiment 1, the difference between the inner diameter of the inner wall 22 of the can and the outer diameter of the barrier ring 24 is 0.2 to 1 mm. As a result, a second first annular heat insulation groove 23 is formed between the barrier ring 24 and the inner wall 22 of the can, which reduces the contact area between the barrier ring 24 and the inner wall 22 of the can, further improving the heat insulation effect, making it less likely for users to be burned, and improving safety.

[0074] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
