Description

Technical Field

[0001] This utility model relates to the technical field of burners, and more specifically, to a top-inlet burner head base. Background Technology

[0002] In top-intake cooktops, the valve body is typically fixed to the lower part of the cooktop, making its outlet relatively close to the lower surface of the cooktop. This means the outlet is roughly level with the bottom of the base's support legs. The burner's nozzle inlet, on the other hand, is usually suspended between the base and the cooktop's bottom. During actual assembly, the significant height difference between the valve body's outlet and the base's inlet necessitates the use of a flexible hose. However, this height difference can cause the hose connection to be easily compressed by the outer wall of the upper side of the inlet pipe, leading to deformation, bending, and potential leaks. Utility Model Content

[0003] In order to overcome the defects of the existing technology, this utility model provides an upper air intake furnace head base to solve the problems in the existing technology.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an upper air intake furnace head base, including a burner support base, a support foot provided at the lower end of the burner support base, a nozzle seat provided on the burner support base, an extension portion that is connected and extends downward at the lower end of the nozzle seat, an air inlet that is connected to the nozzle seat is provided on one side of the lower end of the extension portion, and the lower end surface of the extension portion and the lower end surface of the support foot are located on the same plane.

[0005] In the aforementioned top-inlet burner head base, a protrusion is provided on the side edge of the burner support, the nozzle seat is installed on the upper end of the protrusion, the extension is provided on the lower end of the protrusion, the extension is hollow, and a gas passage is provided inside the nozzle seat.

[0006] In the aforementioned type of top-inlet furnace head base, a nozzle connected to the gas passage is installed on one side of the upper end of the nozzle seat.

[0007] In the aforementioned top-inlet furnace head base, the extension is a vertically arranged support block, and the support block has an inner cavity that communicates with the gas passage. The lower end face of the support block and the lower end face of the support foot are located on the same plane.

[0008] In the aforementioned type of top-inlet furnace head base, the air inlet is located on one side of the lower end of the support block.

[0009] In the aforementioned type of top-inlet furnace head base, a connecting seat is vertically connected to one side of the lower end of the support block, the air inlet is opened on the side of the connecting seat, and a cavity communicating with the inner cavity is provided inside the connecting seat.

[0010] In the aforementioned type of top-inlet furnace head base, the side of the support block is connected to the upper end of the connecting seat by reinforcing ribs.

[0011] In the aforementioned type of upper air intake furnace head base, the air inlet is connected to a valve body connecting pipe, and a valve body connection port is provided at the end of the valve body connecting pipe away from the air inlet.

[0012] The beneficial effects of this utility model are that by extending the extension downwards, the air inlet is set on the lower side of the extension, so that the air outlet is also closer to the bottom of the stove, greatly reducing the height difference between the air inlet and the air outlet of the valve body. This can prevent air leakage caused by the deformation of the hose connection, and the installation is more convenient. At the same time, the extension can cooperate with the support feet for support, improving the stability of the base. Attached Figure Description

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] Example 1 Combination Figures 1 to 3The illustrated upper air intake burner base includes a burner support 1, a support foot 2 at the lower end of the burner support 1, a nozzle seat 4 on the burner support 1, and a downwardly extending extension at the lower end of the nozzle seat 4. An air inlet 8, connected to the nozzle seat 4, is located on one side of the lower end of the extension. The lower end face of the extension and the lower end face of the support foot 2 are on the same plane. In this embodiment, by extending the extension downwards, the air inlet 8 is positioned on one side of the lower end of the extension, thus bringing the air outlet 8 closer to the bottom of the stove. This significantly reduces the height difference between the air inlet 8 and the valve body's air inlet, preventing air leakage due to deformation of the hose connection. Installation is also more convenient. Furthermore, the extension can cooperate with the support foot 2 for support, improving the stability of the base.

[0019] Specifically, in this embodiment, a protrusion 3 is provided on the side edge of the burner support 1, a nozzle seat 4 is installed on the upper end of the protrusion 3, and an extension is provided on the lower end of the protrusion 3. The extension is hollow, and a gas passage is provided inside the nozzle seat 4. The protrusion 3 and the extension are an integral structure, so as to support and install the nozzle seat 4 through the extension, and prevent the burner from being obstructed from being installed on the burner support 1. Among them, a nozzle 5 connected to the gas passage is installed on one side of the upper end of the nozzle seat 4.

[0020] In this embodiment, the extension is a vertically arranged support block 6. The support block 6 has an inner cavity that communicates with the gas passage. The lower end face of the support block 6 and the lower end face of the support leg 2 are on the same plane. The support block 6 is a long strip-shaped block, and its shape can be a cuboid or a cylinder.

[0021] In this embodiment, a connecting seat 7 is vertically connected to one side of the lower end of the support block 6. An air inlet 8 is provided on the side of the connecting seat 7, and a cavity communicating with the inner cavity is provided inside the connecting seat 7. The connecting seat 7 can be a right-angle bend. The air inlet 8 is opened on the side of the connecting seat 7 facing the valve body 12, so that the air inlet 8 and the air outlet of the valve body 12 are on the same straight line. This allows for installation by direct insertion of a rigid pipe or direct connection through a rigid pipe, preventing the connection of the connecting pipe from bending, squeezing and deforming due to height difference, making the stove safer.

[0022] The connecting seat 7 can be integrated with the support block 6. The side of the support block 6 is connected to the upper end of the connecting seat 7 by the reinforcing rib 9, which makes the support block 6 and the connecting seat 7 more solid, prevents bending and deformation, and improves the support performance of the support block 6.

[0023] In some embodiments, the connecting seat 7 and the support block 6 are detachably connected. For example, a protruding threaded section is provided on the connecting seat 7, and the threaded section is threadedly connected to the air inlet 8.

[0024] The air inlet 8 is connected to a valve body connecting pipe 10. The end of the valve body connecting pipe 10 away from the air inlet 8 is provided with a valve body connection port 11. Based on the fact that the air inlet 8 and the air outlet of the valve body 12 are on the same straight line, the valve body connecting pipe 10 can be a straight pipe or a bent pipe to improve the installation flexibility and facilitate the connection of the valve body connection port 11 to the valve body 12.

[0025] Example 2 The difference between this embodiment 2 and embodiment 1 is that the air inlet 8 is opened on one side of the lower end of the support block 6, and the air inlet 8 faces the valve body air outlet of the valve body 12, so that the air inlet 8 can be directly connected to the valve body 12 through the valve body connecting pipe 10, without the need to set the connecting seat 7.

[0026] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
