[0027] The present utility model provides a cylindrical heater 100.

[0028] Please refer to Figures 1 to 4 , in an embodiment of the present utility model, the cylindrical heater 100 includes: a base 1, a combustion device 2, and a radiation tube 3. The combustion device 2 is located above the base 1 and is detachably connected to the base 1; the radiation tube 3 includes at least two radiation segment tubes 31, and the radiation segment tubes 31 are detachably connected to each other in sequence from head to tail. The radiation tube 3 is located on the side of the combustion device 2 facing away from the base 1 and extends along the direction from the base 1 to the combustion device 2; the radiation segment tube 31 closest to the combustion device 2 is detachably connected to the combustion device 2.

[0029] In one embodiment, the base 1 is an important component of the heater. The base 1 not only provides stable support for the heater, ensuring the safety and stability of the entire heater during use, but also includes storage and adjustment functions. Its interior is a hollow structure that can be used to store gas pipes or electric wires and other structures. The bottom is designed with multiple knobs that can be adjusted individually in height to cope with the use on floors of different heights; the panel on the top of the base 1 can bear the weight of the gas cylinder to balance the center of gravity of the entire columnar heater 100 and prevent the columnar heater 100 from tipping over due to unstable center of gravity. The base 1 is generally made of stainless steel or aluminum alloy. Stainless steel has excellent corrosion resistance, high temperature resistance, and good strength, enabling it to maintain stability and durability in humid or high-temperature environments. At the same time, it is easy to clean and has low maintenance costs; the characteristics of aluminum alloy are light weight, good thermal conductivity, easy to process and form, and relatively low cost. Its good heat dissipation performance helps to improve the efficiency of the heater. At the same time, the base 1 made of aluminum material is also relatively easy to carry and move. Both of these materials can provide solid support for the heater, ensuring the safety and reliability of the heater during use.

[0030] In another embodiment, the combustion device 2 includes a regulator, a gas pipe, a safety valve, a pilot flame, a thermocouple, a pulse igniter, a burner, etc. These structures are all assembled in the combustion device 2. The combustion device 2 as a whole is installed above the base 1 of the heater through a bracket or a support structure; due to the independence of the structure of the combustion device 2, it is convenient for maintenance. Moreover, since the combustion device 2 is located inside the heater, the product is more beautiful and has better integration. The regulator is used to control the supply of fuel to ensure combustion efficiency and stability. The gas pipe transports fuel (such as natural gas or liquefied petroleum gas) from the storage container to the burner. The safety valve automatically releases pressure when the pressure is too high to prevent equipment damage or safety accidents. The pilot flame is used to ignite the main burner to ensure the continuity of the combustion process. The thermocouple is used to detect the temperature of the burner to ensure the safety and stability of the combustion process. The pulse igniter ignites the fuel by generating a high-voltage electric spark, which is a fast and reliable ignition method. The burner is a component directly involved in fuel combustion, designed to efficiently and safely convert fuel into heat energy. These components work together to ensure that the combustion device 2 can operate safely and efficiently while providing necessary safety protection measures to prevent accidents.

[0031] The radiant tube 3 is an efficient heat exchanger that can transfer heat with a large surface area, thereby improving the thermal efficiency. The radiant tube 3 is usually made of stainless steel or glass and has good thermal conductivity, enabling it to quickly absorb and dissipate heat. The combustion device 2 transfers the heat generated by fuel combustion to the radiant tube 3, and the heat of the radiant tube 3 is transferred in the form of radiation, which allows it to evenly heat the space without increasing the surrounding air flow. The durability and corrosion resistance of the radiant tube 3 also make it an ideal choice for long-term stable operation, especially suitable for use in equipment that requires continuous high-temperature output. The head and tail of each radiant segment tube 31 are detachably connected in sequence by means of bolts or buckles, etc. The radiant tube 3 is located above the combustion device 2 and extends along the direction from the base 1 to the combustion device 2; the radiant tube 3 adopts a multi-segment design, which is convenient for users to store and transport the column heater 100. The radiant segment tube 31 closest to the combustion device 2 is detachably connected to the combustion device 2 by means of bolts or buckles, further improving the disassembly degree of the entire column heater 100.

[0032] The technical solution of the present utility model divides the radiant tube 3 of the ordinary column heater 100 into two or more segments, and the head and tail of each radiant segment tube 31 are detachably connected in sequence, generally by bolt connection or buckle connection; when the user is using it normally, after assembling the base 1, the combustion device 2 and multiple radiant segment tubes 31 into a complete column heater 100, the heat is transferred to the radiant tube 3 through the combustion device 2 for radiant heating; when storage or mailing is required, each radiant segment tube 31, the combustion device 2 and the base 1 are disassembled respectively. Through the segmented design of the radiant tube 3, when the entire column heater 100 is transported after disassembly, its length will not be limited by the length of the radiant tube 3 and cannot be shortened, resulting in the problem that the column heater 100 is not convenient for mailing, transportation or storage.

[0033] In an embodiment of the present utility model, please refer to Figure 1 and Figure 2 , the column heater 100 further includes a protective net 4. The protective net 4 includes at least two protective segment nets 41, and the head and tail of each protective segment net 41 are detachably connected in sequence. The protective net 4 is located on the side of the combustion device 2 facing away from the base 1 and extends along the direction from the base 1 to the combustion device 2; the protective segment net 41 closest to the combustion device 2 is detachably connected to the combustion device 2. Each protective segment net 41 encloses a protective passage 4a, and the radiant tube 3 is located in the protective passage 4a.

[0034] In one embodiment, the cylindrical heater 100 includes at least two protective segmented nets 41 that are detachably connected by bolts or snaps. These protective segmented nets 41 are connected end to end in sequence, arranged above the combustion device 2, and extend along the direction from the base 1 to the combustion device 2. The protective net 4 is generally made of stainless steel or aluminum alloy. Stainless steel has excellent corrosion resistance, high temperature resistance, and good strength, enabling it to maintain stability and durability in high-temperature environments, while being easy to clean and having low maintenance costs. Aluminum alloy is characterized by being lightweight, having good thermal conductivity, being easy to process and form, and having a relatively low cost. Its good heat dissipation performance helps improve the efficiency of the heater. A protective coating is also applied to the outer layer of the protective net 4 to prevent users from being scalded when using the cylindrical heater 100. The protective net 4 closest to the combustion device 2 is connected to the combustion device 2 by a detachable method such as bolts or snaps. All the protective segmented nets 41 enclose a protective channel 4a, and the radiation tubes 3 are arranged within these protective channels 4a. Such a design not only ensures the safety of the radiation tubes 3 during operation, preventing problems such as scalding of users by the high-temperature radiation tubes 3, but also facilitates the maintenance and cleaning of the combustion device 2 and the radiation tubes 3. The protective net 4 has a suitable size and shape to ensure that the length of the protective net 4 and the protective channel 4a can cover and protect the radiation tubes 3. The protective net 4 is connected in a predetermined sequence and manner to form a continuous protective structure, and finally the radiation tubes 3 are safely installed within the protective channel 4a formed by the protective net 4 to ensure their stability and safety during the heating process.

[0035] In an embodiment of the present utility model, please refer to Figure 1 and Figure 3 , the cross-sectional area of each protective segmented net 41 gradually decreases along the direction from the base 1 to the combustion device 2.

[0036] In another embodiment, the cross-sectional area of each protective segmented net 41 gradually decreases along the direction from the base 1 to the combustion device 2. This design not only improves the aesthetics of the heater but also helps optimize the distribution of heat flow, reduce heat loss, and improve the heating efficiency. Each protective segmented net 41 closest to the combustion device 2 can be sleeved on the adjacent protective segmented net 41. When the merchant needs to mail the cylindrical heater 100 or when the user needs to store the cylindrical heater 100, only need to detach each protective segmented net 41 from the cylindrical heater 100 and stack them in sequence from small to large, which can save storage space and also facilitate the mailing and transportation of the entire cylindrical heater 100.

[0037] In an embodiment of the present utility model, please refer to Figure 1 and Figure 2, the columnar heater 100 includes a cover plate 5, which is located on the side of the protective segmented net 41 farthest from the combustion device 2 and facing away from the combustion device 2, and is detachably connected to the protective segmented net 41 away from the combustion device 2.

[0038] In one embodiment, the cover plate 5 of the columnar heater 100 is designed as a flat or slightly curved plate-like structure. The size of the cover plate 5 matches the top of the radiation tube 3 and can completely cover the topmost protective segmented net 41. The material of the cover plate 5 is selected to be heat-resistant, lightweight and have a certain strength, such as aluminum alloy or stainless steel, to resist deformation under long-term high-temperature heating. A detachable connection method is adopted between the cover plate 5 and the protective segmented net 41 below. This connection is generally a snap connection, a bolt connection or other mechanical locking mechanisms, so that the user can easily remove the cover plate 5 for maintenance or cleaning of the heater when needed. The design of the detachable connection can ensure the stability of the cover plate 5 during use and facilitate disassembly.

[0039] In one embodiment of the present utility model, please refer to Figure 1 , the columnar heater 100 includes a cylinder 6, which is located between the combustion device 2 and the base 1. The cylinder 6 is detachably connected to the base 1 and the base 1. An installation cavity is formed by enclosing the cylinder 6 and the base 1, and the combustion device is located in the installation cavity.

[0040] In one embodiment, a cylinder 6 is provided between the combustion device 2 and the base 1. The cylinder 6 of the columnar heater 100 is designed as a hollow cylindrical structure, and its diameter is the same as that of the combustion device 2, which can provide good support for the combustion device 2, the radiation tube 3 and the protective net 4. The size of the cylinder 6 is adapted to the design of the base 1. The cylinder 6 is detachably connected to the base 1 by bolts or snaps. The material of the cylinder 6 is selected to have good heat resistance and stable structure, such as stainless steel or heat-resistant plastic, to ensure long-term use in a high-temperature environment. The upper and lower ends of the cylinder 6 are respectively connected to the base 1 and the combustion device 2 by threaded or slot connections, realizing the detachable connection between the cylinder 6 and the base 1 and the combustion device 2. An installation cavity is formed by enclosing the cylinder 6 and the base 1. This installation cavity provides installation space for the internal combustion device 2, control components and liquefied gas tank and other structures, and plays a role of protection and support. The design of the installation cavity ensures that the user can easily check and replace the internal components.

[0041] In one embodiment of the present utility model, please refer to Figure 1 and Figure 4 , the columnar heater 100 includes two cylinders 6, the two cylinders 6 are detachably connected, and the two cylinders 6 are located between the base 1 and the radiation tube 3. The cylinder 6 close to the base 1 is detachably connected to the base 1.

[0042] In one embodiment, the cylindrical heater 100 includes two coaxial cylinders 6. The two cylinders 6 are stacked and connected by bolts or snap connections, etc. Users can easily align and lock the two cylinders 6 together to achieve a stable connection. Users can quickly disassemble the cylinders 6 for maintenance or component replacement. At the same time, the design of the two cylinders 6 can make the installation cavity inside the cylinders 6 larger, capable of accommodating a liquefied gas tank and a gas pipe, and can also be used to arrange the internal components of the heater, such as a combustion chamber, a heat exchanger, a control unit, etc., while providing sufficient heat insulation and safety protection.

[0043] In one embodiment of the present utility model, please refer to Figure 4 , each cylinder 6 includes at least two buckle plates 61. The cross-section of the buckle plate 61 along the length direction of the cylinder 6 is arc-shaped, and the buckle plates 61 are detachably connected to each other.

[0044] In one embodiment, each cylinder 6 is composed of a plurality of buckle plates 61 with an arc-shaped cross-section. These buckle plates 61 are made of high-strength and heat-resistant materials, such as stainless steel or aluminum alloy, etc., to ensure stability and safety during the operation of the heater. The cross-section of the buckle plate 61 is designed to be arc-shaped to achieve the continuity and uniformity of the cylinder 6. At the same time, the arc-shaped buckle plate 61 can provide better structural strength. Each buckle plate 61 of each cylinder 6 can be buckled individually or simultaneously. The buckle plates 61 are detachably connected by a hinge structure or snap connection, etc. Specifically, each buckle plate 61 is provided with two hinge structures, which is beneficial to the stability of the installation of the buckle plate 61. The upper and lower cylinders 6 can be switched on and off separately and are switched on and off as a whole after being connected to each other. At the same time, it is also beneficial for users to quickly disassemble and assemble the cylinders 6, which is convenient for storage and mailing and transportation. The edge of the buckle plate 61 is designed with special grooves or protrusions, corresponding to the protrusions or grooves of the adjacent buckle plate 61, and quick locking and unlocking are achieved through sliding or rotating actions. This design allows the buckle plates 61 to be manually disassembled and assembled without using tools when installing, maintaining or replacing the cylinders 6.

[0045] In one embodiment of the present utility model, please refer to Figure 1 , each radiation tube 3 is provided with a plurality of ventilation holes 3a, and the ventilation holes 3a are arranged at intervals along the outer peripheral wall of the radiation tube 3.

[0046] In one embodiment, a plurality of ventilation holes 3a are evenly formed on the outer peripheral wall of the radiation tube 3 to ensure the uniformity of air flow and maximize the heat exchange efficiency. The shape of the ventilation holes 3a is generally circular or oval. The ventilation holes 3a are arranged at intervals along the outer peripheral wall of the radiation tube 3. Such intervals can be in a linear arrangement, a spiral arrangement or other specific geometric arrangements to meet the requirements of aerodynamics and heat transfer. The edges of the ventilation holes 3a are designed to be smooth to reduce the resistance during air flow and prevent the accumulation of dust and impurities. To improve the durability of the ventilation holes 3a and prevent deformation, the ventilation holes 3a are processed by precision machining or laser cutting technology to ensure that the edges of the holes are neat and burr-free. In addition, the setting of the ventilation holes 3a also takes into account the overall structural strength of the radiation tube 3, avoiding opening holes in critical stress concentration areas. The ventilation holes 3a on the radiation tube 3 not only help improve the thermal efficiency of the heater, but also help reduce noise and energy consumption. By reasonably designing the size, shape and distribution of the ventilation holes 3a, the thermal radiation characteristics and air flow pattern of the radiation tube 3 can be effectively controlled to achieve an efficient, quiet and energy-saving heating effect.

[0047] In one embodiment of the present utility model, please refer to Figure 1 , the columnar heater 100 includes an infrared net 32, and the infrared net 32 is located on the side of the radiation tube 3 facing away from the base 1 and is detachably connected to the radiation tube 3.

[0048] In one embodiment, the columnar heater 100 includes an infrared net 32 disposed above the radiation tube 3. The infrared net 32 is generally made of stainless steel or other materials with good heat radiation reflection ability. The shape of the infrared net 32 matches the top of the radiation tube 3 to ensure the prevention of flame overflow. The bottom of the infrared net 32 is connected to the radiation tube 3 by bolts or buckles and other means. The detachable connection method facilitates the disassembly and assembly of the infrared net 32 and is also beneficial for cleaning, maintaining the heater or replacing the infrared net 32. The infrared net 32 has more dense ventilation holes and the ventilation holes are smaller to further improve heat radiation. The installation position of the infrared net 32 is directly above the radiation tube 3 to ensure that the flame inside the radiation tube 3 can be effectively blocked by the infrared net 32, thereby improving the heating efficiency and uniformity.

[0049] In one embodiment of the present utility model, please refer to Figure 2 , the base 1 includes moving wheels 11, and the moving wheels 11 are rotatably connected to the outer side wall of the base 1. The moving wheels 11 are located above the outer bottom wall of the base 1.

[0050] In one embodiment, the base 1 of the columnar heater 100 is provided with moving wheels 11. The moving wheels 11 are made of durable materials such as plastic or rubber to ensure stability and durability under different ground conditions. The moving wheels 11 are rotatably connected to the base 1 through a bearing or a rotating shaft. The moving wheels 11 are installed on the outer side wall of the base 1. In order to improve the convenience of movement and prevent the columnar heater 100 from being unstable during use, the moving wheels 11 are located above the outer bottom wall of the base 1. This design enables the user to move the columnar heater 100 by simply tilting the columnar heater 100 in the direction of the moving wheels 11, making the moving wheels 11 directly contact the ground, thereby realizing the movement of the columnar heater 100 by means of the rolling of the moving wheels 11, which is more labor-saving and convenient while reducing wear on the ground. The base 1 of the heater not only provides the necessary support and stability but also increases the flexibility of movement, enabling the user to easily move the heater to different rooms or positions according to needs, improving its practicality and convenience.
