Description

Technical Field

[0001] This application relates to the field of heating technology, and more specifically, in particular to an outdoor heater with a support tube. Background Technology

[0002] Outdoor gas heaters are commonly used in homes for heating purposes in patios, outdoor shopping malls, and outdoor restaurants. Taking Amazon as an example, products are shipped from the manufacturer to a warehouse, and then from the warehouse to the user's desired destination. However, according to relevant safety regulations, the flame height of outdoor gas heaters must be higher than 1.9 meters (as per the American National Standards Institute standard). Therefore, the support tube of the heater has a minimum length limit. During packaging and transportation, the support tube is often quite long, leading to difficulties in packaging and transportation, and higher shipping costs. Utility Model Content

[0003] The purpose of this application is to address the shortcomings of the prior art and propose an outdoor heater with a support tube that has low transportation costs.

[0004] To achieve the above objectives, this application proposes an outdoor heater with a support tube, including a burner head, a support tube for fixing and supporting the burner head, and a base assembly for supporting and fixing the support tube. The support tube includes an upper tube and a lower tube, which are disassembled during transportation and can be assembled at the destination. After the support tube is assembled, the upper end of the lower tube is fixedly connected to the lower end of the upper tube, and the upper end of the upper tube is fixedly connected to the burner head.

[0005] At the connection between the upper tube and the lower tube, one of the upper tube and the lower tube has a first snap-fit ​​portion and the other has a second snap-fit ​​portion, and the first snap-fit ​​portion and the second snap-fit ​​portion are adapted to each other for detachable connection or snap-fit.

[0006] The second snap-fit ​​portion includes a first receiving portion and a second receiving portion, wherein the first receiving portion is connected to the second receiving portion.

[0007] The first receiving portion has a groove, and the second receiving portion has a through hole, wherein the groove of the first receiving portion communicates with the through hole of the second receiving portion.

[0008] During assembly, the first snap-fit ​​portion snaps into the second receiving portion via the first receiving portion. When assembly is complete, the first snap-fit ​​portion is partially or entirely housed in the second receiving portion.

[0009] The upper wall of the second receiving part is inclined, and in the vertical direction of the support tube, the height of the upper wall at the end away from the first receiving part is less than the height at the end near the first receiving part.

[0010] At the connection between the burner head and the upper pipe, one of the upper pipe and the burner head has a first snap-fit ​​part, and the other has a second snap-fit ​​part, and the first snap-fit ​​part and the second snap-fit ​​part are adapted to each other for detachable connection or snap-fit.

[0011] Both the upper tube and the lower tube are provided with matching fixing holes, which are fixed with bolts or screws; both the upper tube and the burner head are provided with matching fixing holes, which are fixed with bolts or screws.

[0012] The support tube includes a foot plate. At the connection between the lower tube and the foot plate, one of the lower tube and the foot plate has a first snap-fit ​​portion, and the other has a second snap-fit ​​portion. The first snap-fit ​​portion and the second snap-fit ​​portion are adapted to each other for detachable connection or snap-fit; or, the lower tube and the foot plate are welded and fixed.

[0013] The foot plate includes a locking part and a third receiving part. The bottom assembly includes a foot tube, and the foot tube includes a locking hole. The locking part is adapted to the locking hole. After installation, part of the foot tube is received in the third receiving part, and part or all of the locking part is received in the locking hole.

[0014] Beneficial effects:

[0015] As can be seen from the above technical solutions, this application has the following advantages compared with the prior art:

[0016] 1. The support tube is split into upper and lower tubes during transportation, which reduces the length of the packaging and thus reduces packaging and transportation costs. At the same time, the upper and lower tubes are assembled at the destination to meet the height requirements of the heater.

[0017] 2. The upper and lower tubes are snapped together using the first and second connecting parts, which not only makes it convenient for users to assemble, but also allows users to repeatedly disassemble and reassemble, making it convenient for users to store and assemble.

[0018] 3. The first connecting part enters from the first receiving part and is finally snapped into the second receiving part. This setting results in low coaxiality between the upper and lower tubes after installation, making the support tube straighter.

[0019] 4. The burner head and the upper tube adopt the same connection method as the lower tube, which is convenient for users to store and assemble, and has the advantage of low coaxiality.

[0020] 5. Fixing holes are provided at the connection between the upper and lower pipes, and bolts or screws are used to fix them in place, which improves the stability of the connection between the upper and lower pipes.

[0021] 6. The upper wall of the second receiving part is inclined, which makes it easier for the first connecting part to enter the second receiving part, making it convenient for users to install.

[0022] 7. The foot plate is equipped with a third receiving part and a locking part, which improves the convenience of foot tube and foot plate installation. Attached Figure Description

Detailed Implementation

[0035] The embodiments of this application will now be clearly and completely described with reference to the accompanying drawings.

[0036] Please refer to Figures 1 to 10 As shown, an outdoor heater with a support tube 3 according to this application includes a reflector cover 1, a support tube 3, a burner head 2, and a base assembly. The base assembly supports the support tube 3, and the support tube 3 supports the burner head 2. The base assembly includes a barrel 4, foot tubes 6, and a base 5. After the heater is installed, the base 5 is fixed to the bottom of the foot tubes 6, the top of the foot tubes 6 is fixed to the bottom of the support tube 3, the top of the support tube 3 is fixed to the bottom of the burner head 2, and the top of the burner head 2 is fixed to the reflector cover 1.

[0037] The bottom of the foot tube 6 is detachably connected to the base 5 by bolts, the top of the foot tube 6 is detachably connected to the bottom of the support tube 3 by bolts, and the top of the support tube 3 is detachably connected to the bottom of the burner head 2 by bolts. It is understood that bolt connections include screws, bolts, etc., and detachable connections include snap-fit ​​connections, threaded connections, etc.

[0038] Please refer to the figure. The support tube 3 includes an upper tube 31, a lower tube 32, and a foot plate 33. The upper tube 31 and the lower tube 32 are detachably connected. The lower tube 32 and the foot plate 33 can be detachably connected, such as by snap-fit, bolt connection, or internal and external thread screw connection, or they can be fixedly connected, such as by welding or integral molding. In this embodiment, the lower tube 32 and the foot plate 33 are detachably connected. The upper tube 31 and the lower tube 32 are in a disassembled state during transportation to reduce the packaging length during transportation. At the destination, the upper tube 31 and the lower tube 32 can be assembled and fixed.

[0039] The specific assembly method and structure are as follows: one of the upper tube 31 and the lower tube 32 has a first snap-fit ​​portion 311, and the other has a second snap-fit ​​portion 321. In this embodiment, the upper tube 31 has the first snap-fit ​​portion 311, and the lower tube 32 has the second snap-fit ​​portion 321. Both the upper tube 31 and the lower tube 32 have fixing holes 312, and the first snap-fit ​​portion 311 and the second snap-fit ​​portion 321 are adapted to each other. The fixing holes 312 in the upper tube 31 are adapted to and correspond one-to-one with the fixing holes 312 in the lower tube 32. The first snap-fit ​​portion 311 is a protruding structure that protrudes into the interior of the upper tube 31, and can be formed by extrusion. The sidewalls of the protruding structure are inclined. The second snap-fit ​​portion 321 includes a first receiving portion 3211 and a second receiving portion 3212. The first receiving portion 3211 is a groove structure. The first receiving portion 3211 can partially or completely accommodate the first snap-fit ​​portion 311, that is, the protruding structure is partially or completely accommodated in the first receiving portion 3211. The first receiving portion 3211 is a vertically extending groove structure, with the opening of the groove pointing radially outward along the lower tube 32, and the bottom wall of the groove protruding into the interior of the lower tube 32. The second receiving portion 3212 is a through-hole structure, which communicates with the groove structure.

[0040] The protruding structure of the first latching portion 311 is adapted to the through-hole structure of the second receiving portion 3212. The outer contour of the protruding structure is adapted to the contour of the hole in the through-hole structure; that is, when the protruding structure is circular, elliptical, or polygonal, the hole in the through-hole structure is correspondingly circular, elliptical, or polygonal. In this embodiment, the protruding structure and the through-hole structure are quadrilateral structures, and the upper wall of the through-hole is inclined. In the vertical direction of the support tube 3, the height of the end away from the first receiving portion 3211 is less than the height of the end close to the first receiving portion 3211, which facilitates the installation of the protruding structure and the through-hole. When the protruding structure is partially or completely accommodated in the through-hole structure, the first latching portion 311 and the second latching portion 321 are installed.

[0041] The through-hole structure of the second receiving part 3212 is located at one end of the groove structure of the first receiving part 3211 along the length direction. The other end of the groove structure is a flared structure. The flared structure gradually narrows in the direction close to the through-hole structure, so that the protrusion structure of the first snap-fit ​​part 311 can enter the groove structure.

[0042] The second snap-fit ​​portion 321 located in the lower tube 32 is housed inside the upper tube 31. During the assembly of the upper tube 31 and the lower tube 32, the protruding structure of the first snap-fit ​​portion 311 moves downward from the top of the lower tube 32 along the groove structure of the first receiving portion 3211. At this time, the protruding structure is partially housed inside the groove structure and moves along the length direction of the groove structure. When the protruding structure moves to the bottom of the groove structure along the length direction, the protruding structure rotates towards the through hole structure, so that the protruding structure is finally snapped onto the through hole structure, realizing the assembly of the first snap-fit ​​portion 311 and the second snap-fit ​​portion 321. That is, when the assembly is completed, the first snap-fit ​​portion 311 is housed entirely or partially in the second receiving portion 3212, and at this time, the upper end of the lower tube 32 supports and fixes the lower end of the upper tube 31, and the upper end of the upper tube 31 supports and fixes the lower end of the burner head 2.

[0043] After the first snap-fit ​​part 311 and the second snap-fit ​​part 321 are installed, the fixing hole 312 located on the upper tube 31 and the fixing hole 312 located on the lower tube 32 correspond to each other, and the inner wall of the fixing hole 312 located on the lower tube 32 is provided with threads, so that the upper tube 31 and the lower tube 32 are fixed by bolts or screws. Through the snap-fit ​​of the first snap-fit ​​part 311 and the second snap-fit ​​part 321, and the screwing of bolts or screws, the upper tube 31 and the lower tube 32 are fixed by the combined action of the two fixing methods. Under the dual action, the stability of the upper tube 31 and the lower tube 32 is improved.

[0044] There are multiple first snap-fit ​​portions 311 and fixing holes 312 on the upper tube 31, and multiple second snap-fit ​​portions 321 and fixing holes 312 on the lower tube 32, each corresponding one-to-one with the first snap-fit ​​portions 311 and fixing holes 312 on the upper tube 31. In this embodiment, at the connection between the upper tube 31 and the lower tube 32, there are three first snap-fit ​​portions 311 and three second snap-fit ​​portions 321, and one fixing hole 312 on each. After the first snap-fit ​​portions 311 and the second snap-fit ​​portions 321 are installed, the user only needs to fix them with screws once, which reduces the convenience of installing the upper tube 31 and the lower tube 32 and reduces the assembly time.

[0045] When the protruding structures of the three first snap-fit ​​parts 311 are respectively accommodated in the through-hole structures of the three second accommodating parts, the protruding structure is partially accommodated in the through-hole structure, that is, the side wall of the protruding structure is snapped onto the inner wall of the through-hole, which reduces the gap between the protruding structure and the through-hole, thereby reducing the shaking of the connection between the upper tube 31 and the lower tube 32. At the same time, at the connection between the upper tube 31 and the lower tube 32, the inner wall of the upper tube 31 and the outer wall of the lower tube 32 fit together, which improves the coaxiality of the upper tube 31 and the lower tube 32 after connection, making the heater straighter after installation.

[0046] The lower end of the upper pipe 31 is connected to the upper end of the lower pipe 32, the upper end of the upper pipe 31 is connected to the lower end of the burner head 2, and the lower end of the lower pipe 32 is connected to the foot plate 33. The connection method between the upper pipe 31 and the burner head 2 is the same as the connection method between the upper pipe 31 and the lower pipe 32, and the connection method between the lower pipe 32 and the foot plate 33 is the same as the connection method between the upper pipe 31 and the lower pipe 32. The connection between the upper pipe 31 and the burner head 2 is also achieved through the first snap-fit ​​part 311 and the second snap-fit ​​part 321. At the connection between the upper pipe 31 and the burner head 2, one of the upper pipe 31 and the burner head 2 has the first snap-fit ​​part 311, and the other has the second snap-fit ​​part 321. At the same time, the upper pipe 31 and the burner head 2 have corresponding multiple fixing holes 312, and the fixing holes 312 are threaded, so that the upper pipe 31 and the burner head 2 can be further fixed with bolts. The connection between the lower pipe 32 and the foot plate 33 is also achieved through the first snap-fit ​​part 311 and the second snap-fit ​​part 321. At the connection between the lower pipe 32 and the foot plate 33, one of the lower pipe 32 and the foot plate 33 has the first snap-fit ​​part 311, and the other has the second snap-fit ​​part 321. At the same time, the lower pipe 32 and the foot plate 33 have corresponding multiple fixing holes 312, and the fixing holes 312 are threaded, so that the upper pipe 31 and the burner head 2 can be further fixed with bolts. It is understood that the upper pipe 31 and the burner head 2 can be fixed by welding, and the lower pipe 32 and the foot plate 33 can be fixed by welding. In this embodiment, the upper pipe 31 and the burner head 2 are connected by a first snap-fit ​​part 311 and a second snap-fit ​​part 321, and the lower pipe 32 and the foot plate 33 are fixed by welding.

[0047] The upper end of the foot plate 33 is connected to the lower end of the lower tube 32, and the lower end of the foot plate 33 is fixedly connected to the foot tube 6. Specifically, the foot tube 6 includes a third receiving portion 331, which also has a groove structure. A portion of the foot tube 6 is accommodated within the groove structure of the third receiving portion 331 to improve the stability of the connection between the foot tube 6 and the foot plate 33. Fixing holes 312 are provided on both the foot plate 33 and the foot tube 6 for bolt fixing, further improving the stability of the connection between the foot plate 33 and the foot tube 6.

[0048] The foot plate 33 is provided with a locking part 332, and the foot tube 6 is provided with a locking hole 61. The locking part 332 extends from the foot plate 33 towards the foot tube 6. When the foot plate 33 and the foot tube 6 are installed, the locking part 332 is partially or completely accommodated in the locking hole 61, so that the locking part 332 is engaged with the foot tube 6. At this time, part of the foot tube 6 is accommodated in the groove structure of the third receiving part 331, so that the foot plate 33 and the foot tube 6 are engaged and fixed. At the same time, the dual function of the locking hole 61, the locking part 332, and the third receiving part 331 improves the stability of the connection between the foot tube 6 and the foot plate 33. Furthermore, after the foot tube 6 and the foot plate 33 are engaged and fixed, the fixing hole 312 on the foot tube 6 and the fixing hole 312 on the foot plate 33 are opposite and compatible. Bolts are used to pass through the fixing hole 312 to fix the foot tube 6 and the foot plate 33, which improves the stability of the connection between the foot plate 33 and the foot tube 6. Meanwhile, there are two fixing holes 312 on the foot tube 6 and two fixing holes 312 on the foot plate 33, and the two fixing holes 312 form a straight line to prevent rotation.
