Description

Technical Field

[0001] This invention relates to a heating device, and more particularly to an umbrella-shaped heater. Background Technology

[0002] The umbrella-shaped heater is a heating device that uses gas combustion technology. It features a high-efficiency stainless steel heat dissipation mesh, a durable and corrosion-free body made of thickened steel plate, and a sturdy gas cylinder placed inside for easy operation. The arc-shaped adjustment allows for high, medium, and low heat settings to meet different heat needs. The maximum power reaches 15KW and above, which is six times that of ordinary heaters. It uses liquefied petroleum gas (natural gas) as fuel, which is dust-free, odorless, noiseless, highly efficient, and environmentally friendly, with a combustion rate of 99.9%.

[0003] Existing umbrella-shaped heaters typically consist of a gas cylinder at the bottom, covered by a metal casing. A gas pipe connects to the top of the cylinder, and the burner is located above the support pipe. Above the burner is a top cover used to reflect heat. However, current umbrella-shaped heaters are too large, resulting in high packaging costs, especially with rising export container costs, significantly increasing transportation costs. Furthermore, the top cover cannot be adjusted, limiting the heat reflection angle and failing to meet user needs. Summary of the Invention

[0004] This invention provides an umbrella-shaped heater whose components can be disassembled, thereby greatly reducing packaging volume, lowering transportation costs, and improving economic efficiency. At the same time, the angle of the top cover can be adjusted to meet the needs of different users. It solves the technical problems of existing umbrella-shaped heaters, which have a monolithic structure, resulting in large packaging volume, high transportation costs, and an inability to adjust the angle of the top cover.

[0005] The above-mentioned technical problem of the present invention is solved by the following technical solution: an umbrella-shaped heater, comprising a base component, a support tube and a burner component;

[0006] The base component includes a base for placing the gas cylinder;

[0007] The base component also includes a base frame located outside the gas cylinder, on which the gas cylinder is placed. The base frame can then limit the gas cylinder in the circumferential direction, and can also be used to fix the base to the support pipe.

[0008] The base component also includes a cover located outside the base frame to shield the gas cylinder. The cover is flexible. The base frame can also provide circumferential support for the cover and provide installation space for the gas cylinder in the support pipe.

[0009] The support pipe is used to support the burner and to house the gas pipeline. The two ends of the gas pipeline are connected to the burner and the gas cylinder, respectively.

[0010] The burner component includes a burner, which is connected to a control switch;

[0011] The burner assembly also includes a top cover located above the burner, which is used to reflect the heat from the burner.

[0012] The purpose of the cover is simply to shield the gas cylinder from exposure; it does not need to bear any force or weight. Previously, rigid covers were bulky and had high production and transportation costs. Flexible covers, on the other hand, are soft, foldable, and small in size, facilitating transportation and significantly reducing production and transportation costs. After all components of the product are packaged and transported to their destination, during assembly, once the burner components are assembled and the gas cylinder is placed on the base, the flexible cover can be directly opened and fitted over the base frame.

[0013] To ensure the flexible housing remains flat outside the base frame and improves the overall aesthetics of the umbrella-shaped heater, a preferred embodiment is a housing flattening structure. This flattening structure provides an upward pushing and downward pulling force to the housing, allowing the flexible housing to flatten outside the base frame.

[0014] Preferably, the flattening structure of the cover includes an upper fixing ring that fits onto the support tube. A compression spring is located below the fixing ring, with the other end of the spring abutting against the base frame. The compression force of the spring presses against the upper fixing ring, providing an upward pulling force to the flexible cover.

[0015] Preferably, the flattening structure of the cover also includes a lower fixing member, which is located below the cover and is made of metal. A magnet is provided below the base, and the lower fixing member is attracted to the base to flatten the cover. The magnet on the base holds the lower fixing ring, providing a downward pulling force to the flexible cover.

[0016] The lower fixing component can be an evenly distributed arc-shaped block at the lower ring of the cover, or it can be a whole circular ring installed at the bottom of the cover. Preferably, the lower fixing component is a metal ring, which passes through the bottom surface of the cover.

[0017] Preferably, the casing is made of textile or plastic materials, such as polyester, PG fabric, nylon fabric, Oxford cloth, and canvas, but not limited to these materials.

[0018] Preferably, the top cover is umbrella-shaped and made of a textured board, corrugated board, or board with a embossed surface. This improves heat reflection efficiency.

[0019] As a preferred embodiment, the top cover is integrally molded.

[0020] Alternatively, the top cover is composed of 2 to 9 cover panels joined together, with adjacent cover panels connected by connectors. Each connector is a long, narrow plate with a snap-fit ​​groove on each side. The cover panels are inserted into these grooves and then tightened with screws. This design results in small cover panels, facilitating transportation and reducing costs.

[0021] Preferably, a reflector adjustment structure is also installed on the top cover. This structure is used to adjust the angle of the top cover. The reflector adjustment structure includes an adjustment bracket fixed above the burner. The adjustment bracket includes two parallel adjustment plates with guide grooves on them. A positioning shaft is located below the top cover, with both ends of the positioning shaft positioned within the guide grooves of the two adjustment plates. The length of the positioning shaft is slightly greater than the distance between the two adjustment plates. The angle of the top cover can be adjusted using the reflector adjustment structure according to the user's needs to obtain the maximum heating area.

[0022] Preferably, the guide rail groove includes a horizontal guide rail groove and an inclined guide rail groove, which are not connected. The starting end of the inclined guide rail groove is on the same straight line as the horizontal guide rail groove, ensuring the position of the top cover. It can be horizontal or inclined.

[0023] Preferably, parallel baffles are fixed below the top cover, and two parallel positioning shafts are fixed between the two baffles. The ends of the positioning shafts pass through guide rail grooves and are fixed to the baffles. One positioning shaft is located in a horizontal guide rail groove, and the other positioning shaft is located in an inclined guide rail groove. The positioning shaft located in the horizontal guide rail groove is a horizontal positioning shaft, and the positioning shaft located in the inclined guide rail groove is an inclined positioning shaft. The horizontal positioning shaft determines the position of the top cover, and the inclined positioning shaft is driven to provide support for the top cover.

[0024] As a preferred embodiment, the horizontal guide rail groove is provided with a positioning slot at both its starting and ending ends. When the horizontal positioning shaft is located within the positioning slot, the inclined positioning shaft is located at the starting end of the inclined guide rail groove, and the two positioning shafts are on the same straight line, thus keeping the top cover horizontal. When the horizontal positioning shaft is located at the end of the horizontal guide rail groove, the inclined positioning shaft is located within the inclined positioning slot, providing support for the top cover and allowing the top cover to be tilted at an angle, thereby completing the adjustment of the top cover angle.

[0025] To allow for infinitely many angle adjustments, as another preferred option, the horizontal guide rail groove is evenly distributed with multiple positioning slots. When the horizontal positioning shaft is located in different positioning slots, the top cover is at different angles.

[0026] Preferably, a hook rod can be sleeved on the positioning shaft, with the hook at the front end of the hook rod sleeved on the positioning shaft. The hook rod pushes or pulls the positioning shaft along the horizontal guide groove. The hook at the front end of the hook rod hooks onto the positioning shaft. By operating the hook rod, the horizontal positioning shaft is driven to move within the horizontal guide groove, determining the position of the horizontal positioning shaft, thereby completing the adjustment of the top cover position.

[0027] Preferably, a push rod is hinged to the positioning shaft for pushing or pulling the positioning shaft along the horizontal guide groove.

[0028] Preferably, the burner includes at least one ring of flame outlets, but may also have two or three rings.

[0029] Preferably, the support tube has a segmented structure, consisting of multiple hollow tubes connected together, with a sealing ring between two adjacent hollow tubes.

[0030] Preferably, adjacent hollow tubes are connected by threads or by snap-fit ​​connections.

[0031] The flexible shell allows for easy folding, reducing the overall packaging volume of the umbrella-shaped heater. The support tube is also segmented, and the top cover is composed of multiple panels, further reducing packaging size, lowering transportation costs, and improving economic efficiency. Additionally, an adjustable reflector structure on the top cover allows for changes in the angle or direction of the reflective surface, catering to users at different viewing angles.

[0032] Therefore, the umbrella-shaped heater of the present invention has the following advantages: the top cover is divided into multiple top cover plates, the support tube is divided into multiple branch tubes, and the shell is made into a flexible shell. This greatly reduces the packaging volume, thereby reducing transportation costs and improving economic efficiency. At the same time, a reflective surface adjustment structure is installed on the top cover, allowing the reflective surface of the top cover to be adjusted in angle and range according to the user's needs, improving the product's flexibility.

[0042] The technical solution of the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0043] Example 1:

[0044] like Figure 1 and 2 As shown in Figure 3, an umbrella-shaped heater includes a top cover 1, a burner 2 arranged from top to bottom, the burner 2 having a burner switch 3, a support tube 4, a base frame, a cover 5 covering the base frame, and a base 6 below the base frame.

[0045] The base 6 is circular and welded to the base frame. The base frame consists of three support rods 8, two of which are on the same diameter. The projection of the three support rods 8 along the axial direction of the support tube forms an isosceles triangle. One end of each support rod 8 is welded to the base 6, and the other end is welded to a fixing plate, which is fixed to the support tube. The gas cylinder is placed onto the base between two adjacent support rods. A top cover 7, which is disc-shaped, is installed on the base frame and fits over the support tube 4. The bottom of the top cover is supported by the fixing plate. A cover 5, made of nylon fabric, covers the gas cylinder and the base frame from the top cover 7 downwards. A metal upper fixing ring 9 is sewn into the center of the cover and fits over the support tube 4. A compression spring 10 is installed below the upper fixing ring 9, with one end abutting against the upper fixing ring 9 and the other end abutting against the base. The cover is cylindrical, and a lower fixing ring 13 is sewn at the lower end of the cover. The lower fixing ring 13 is a ring-shaped metal ring. A magnet 12 is installed on the bottom surface of the base. The magnet 12 attracts the lower fixing ring to the base 6. At the same time, the elastic force of the compression spring 10 pushes the upper fixing ring 9 upward, thereby flattening and expanding the flexible cover made of nylon cloth.

[0046] like Figure 4 and 5As shown, the support tube 4 is a hollow tube, and the upper end of the support tube 4 is connected to the burner 2, which has 2-3 exhaust ports. Two parallel adjusting plates 14, shaped like right trapezoids, are installed above the burner 2. The two adjusting plates 14 form an adjusting bracket. A horizontal guide groove 18 is formed on the upper horizontal edge of the adjusting plate 14, and an inclined guide groove 17 is formed on the inclined edge of the adjusting plate. The starting end of the inclined guide groove 17 is on the same straight line as the horizontal guide groove 18. The horizontal guide groove 18 and the inclined guide groove 17 are not connected. A recessed positioning slot 19 is located at the starting end of the horizontal guide groove 18.

[0047] like Figure 6 As shown, a top cover 1 is installed above the adjustment bracket. The top cover is composed of multiple equally sized fan-shaped bean-patterned plates 21 spliced ​​together. Adjacent bean-patterned plates 21 are connected by long strip connectors 20. The cross-section of the connector 20 is "I" shaped, and slots are opened on both sides of the connector. The bean-patterned plates are inserted into the slots and then fixed to the connector with screws.

[0048] Two parallel baffles 24 are installed below the top cover 1. Two parallel positioning shafts are fixed between the two baffles 24. The ends of the positioning shafts pass through the guide rail grooves on the adjusting plate and are fixed by nuts. One positioning shaft is located in the horizontal guide rail groove and is called the horizontal positioning shaft 16; the other is located in the inclined guide rail groove and is called the inclined positioning shaft 15.

[0049] When the horizontal positioning shaft 16 is located in the positioning slot 19 of the horizontal guide rail groove 18, the inclined positioning shaft 15 is located at the starting end of the inclined positioning groove 17, thereby ensuring that the top cover is in a horizontal state.

[0050] When the horizontal positioning shaft moves to the end of the horizontal guide groove, the tilting positioning shaft slides downward along the tilting positioning groove, causing the top cover to tilt. Since the horizontal guide groove and the tilting guide groove are not connected, when the horizontal positioning shaft moves to the end of the horizontal guide groove, it will not slide back to the starting end due to the gravity of the top cover, thus causing the top cover to tilt.

[0051] Of course, when adjusting the top cover, it can be done by using a hook rod with a hook. The hook rod hangs the hook on the horizontal positioning shaft, and then pulls or pushes the horizontal positioning shaft to move within the horizontal guide rail, thereby adjusting the angle of the top cover.

[0052] Example 2:

[0053] like Figure 7 As shown, unlike Embodiment 1, the horizontal guide rail groove 18 on the adjustment plate has multiple positioning slots 19 evenly distributed on it. When the horizontal positioning shaft 16 is located in different positioning slots 19, the tilt angle of the top cover is different, thereby realizing the adjustment of the top cover at different angles.

[0054] Example 3:

[0055] like Figure 8 As shown, unlike embodiments 1 and 2, the support tube is composed of multiple hollow tubes 22, with sealing rings 23 sleeved between adjacent hollow tubes, and adjacent hollow tubes are connected by threads.

[0056] Example 4:

[0057] like Figure 9 As shown, unlike embodiments 1 and 2, a push rod 26 is hinged to the horizontal positioning shaft via a hinge 25, which is used to push or pull the positioning shaft 16 to move along the horizontal guide groove.
