[0042] The existing upper air intake combustion device includes an anti-dry burning probe, an ignition needle and a thermocouple. The anti-dry burning probe, ignition needle and thermocouple are usually directly fixed on the burner head with a retaining ring or a spring, and then the anti-dry burning probe, ignition needle and thermocouple are fixed with fasteners such as screws. When repairing the upper air intake combustion device designed in this way, it is necessary to remove the burner head, release the screws and then replace the anti-dry burning probe or ignition needle or thermocouple. Since components such as the anti-dry burning probe, ignition needle and thermocouple are easily damaged, the frequent disassembly and assembly process may easily cause the anti-dry burning probe, ignition needle and thermocouple to wear out, resulting in the inability to align with the original installation position, causing certain defects in subsequent use by users.

[0043] In addition, in the above-mentioned prior art, if only one of the anti-dry-burning probe, the ignition needle and the thermocouple needs to be replaced, the burner head still needs to be dismantled as a whole, which is inconvenient for users.

[0044] Therefore, the technical problem solved by the present invention is how to reasonably adjust the installation method of the anti-dry burning probe, the ignition needle and the thermocouple.

[0045] In an embodiment of the present invention, Figure 1 As shown, a top-inlet combustion device comprises a base 1 and a burner head 2, wherein the burner head 2 is installed above the base 1;

[0046] An installation cavity 11 is formed between the base 1 and the burner head 2, and a bracket 3 is arranged in the installation cavity 11. The bracket 3 is provided with a position for installing and fixing an anti-dry burning probe, an ignition needle and a thermocouple, and the bracket 3 is detachably mounted on the base 1.

[0047] A top-inlet combustion device of the present embodiment includes a base 1 and a burner head 2, wherein the burner head 2 is installed above the base 1, and an installation cavity 11 is formed between the base 1 and the burner head 2. A bracket 3 is provided in the installation cavity 11, and a position for installing and fixing an anti-dry-burning probe, an ignition needle and a thermocouple is formed on the bracket 3, and the bracket 3 is detachably installed on the base 1. By installing the anti-dry-burning probe, the ignition needle and the thermocouple through a bracket 3, the anti-dry-burning probe, the ignition needle and the thermocouple can be taken out by removing the bracket 3, thereby making it easier for users to install and disassemble.

[0048] Moreover, the anti-dry burning probe, ignition needle and thermocouple are installed on the bracket 3, so that the anti-dry burning probe, ignition needle and thermocouple are relatively independent from the burner head 2, and the burner head 2 will not affect the installation of the anti-dry burning probe, ignition needle and thermocouple.

[0049] It should be added that, in the process of replacing the anti-dry-burning probe, ignition needle and thermocouple on the bracket 3, if the replacement is frequent, it will cause the bracket 3 and the anti-dry-burning probe, ignition needle and thermocouple to loosen. Since the bracket 3 and the base 1 are detachably installed, and the bracket 3 and the burner head 2 are relatively separated, only the bracket 3 needs to be replaced, which can also save the user's usage cost.

[0050] In this embodiment, if Figure 1 As shown, in order to facilitate the installation and positioning of the bracket 3, a local position of the bottom of the base 1 protrudes upward to form a step 12, and the bracket 3 is installed on the step 12;

[0051] The purpose of setting the step 12 is to provide an installation position for the bracket 3. Preferably, the surface of the step 12 is flat to facilitate stable installation of the bracket 3.

[0052] In addition, a mounting hole 13 is provided on the step 12 , and a mounting block partially protrudes downward at the bottom of the bracket 3 , and the position of the bracket 3 is fixed by placing the mounting block in the mounting hole 13 .

[0053] After the mounting block is placed in the mounting hole 13 , the edge of the mounting block can abut against the inner wall of the mounting hole 13 , so that the position of the bracket 3 can be positioned in the horizontal direction.

[0054] In addition, the installation hole 13 is set on the step 12 to facilitate the installation of the anti-dry-burning probe, ignition needle and thermocouple. Generally, the components of the anti-dry-burning probe, ignition needle and thermocouple are relatively long and need to be set through the base 1 to facilitate the connection with the electrical circuit. Therefore, the installation hole 13 can facilitate the routing of the electrical circuit.

[0055] In this embodiment, if Figure 2As shown, the bracket 3 includes a bottom plate 31 and a column 32 arranged on the bottom plate 31, and a first clamping position 331, a second clamping position 321 and a third clamping position 322 are respectively provided above the bottom plate 31 for installing and fixing the anti-dry burning probe, the ignition needle and the thermocouple;

[0056] The second latching position 321 and the third latching position 322 are integrated in a column 32;

[0057] The first latching position 331 is disposed at one end of the bracket 3 and is disposed opposite to the column 32 .

[0058] The anti-dry burning probe is usually set on the central axis of the upper air inlet combustion device, and the ignition needle and the thermocouple are usually set around the central axis. In order to distinguish the installation position of the anti-dry burning probe from the ignition needle and the thermocouple, the first clamping position 331 is set at one end of the bracket 3 and is arranged opposite to the column 32.

[0059] Since the ignition needle and the thermocouple are used at the same time, the second clamping position 321 and the third clamping position 322 for mounting the ignition needle and the thermocouple are integrated into one column 32 .

[0060] In this embodiment, if Figure 2 As shown, the bottom plate 31 has a plurality of fixing holes 311 , and the mounting hole 13 is provided with a fixing piece 131 matched with the fixing hole 311 , and the fixing piece 131 is opposite to the fixing hole 311 .

[0061] The bracket 3 is fixed on the bottom plate 31 by screws, bolts, etc. passing through the fixing member 131 and the fixing hole 311 aligned with the fixing member 131 in sequence.

[0062] In this embodiment, the fixing holes 311 are preferably two, and correspondingly, the fixing parts 131 are provided with two, and the two fixing holes 311 are arranged on both sides of the bottom plate 31, which is convenient for alignment with the fixing parts 131 and avoids the fixing parts 131 being too long to affect the installation or routing of the anti-dry burning probe, the ignition needle and the bottom of the thermocouple.

[0063] In this embodiment, if Figure 2 As shown, in order to stabilize the structure of the bracket 3, a reinforcing plate 34 is provided between the column 32 and the third clamping position 322, and both ends of the reinforcing plate 34 are integrally formed with the column 32 and the third clamping position 322 respectively.

[0064] Since the application environment of the upper air inlet combustion device is a high temperature environment, a reinforcing plate 34 is provided in the interval area between the column 32 and the third clamping position 322 to prevent the bottom plate 31 from bending and deforming.

[0065] In this embodiment, if Figure 2As shown, in order to realize the installation of the anti-dry burning probe, the bottom plate 31 is further provided with a T-shaped column 35 and a fastener 36, and the first clamping position 331 is provided on the T-shaped column 35;

[0066] The upper portion of the T-shaped column 35 is narrowed to form a vertical plate 351 , and the vertical plate 351 cooperates with the fastener 36 to clamp and install the anti-dry-burning probe.

[0067] The anti-dry-burning probe is fixed on the first clamping position 331 by screws, bolts, etc. passing through the fastener 36 and the vertical plate 351 in sequence.

[0068] In this embodiment, preferably, the fastener 36 is provided with two screw holes 361 arranged diagonally. When fixed by screws or bolts, the fastener 36 can be tightly attached to the vertical plate 351 to prevent one side of the fastener 36 from tilting up, causing the anti-dry-burning probe to be misplaced or loosened.

[0069] In this embodiment, if Figure 2 As shown, the vertical plate 351 has a first fixing groove 3511 therein;

[0070] The fastener 36 has a second fixing groove 362;

[0071] The first fixing groove 3511 and the second fixing groove 362 both have a plurality of convex strips 371 spaced apart from each other.

[0072] A plurality of convex strips 371 spaced apart from each other form a plurality of concave positions, and a convex ring is provided at the lower end of the anti-dry-burning probe. When the fastener 36 and the vertical plate 351 are installed, a plurality of concave rings are formed in the first clamping position 331, and the convex ring is embedded in the concave ring to position and install the anti-dry-burning probe.

[0073] In addition, according to the above, a plurality of concave rings are vertically stacked and arranged. Due to the setting of the mounting hole 13, the convex ring on the anti-dry-burning probe can be embedded in any of the concave rings, so that the anti-dry-burning probe can be installed at multiple different height positions.

[0074] In this embodiment, if Figure 3 As shown, the burner head 2 includes a fire cover 21, a coupling member 22 for mounting the fire cover 21, and a venturi tube member 23 located at the bottom of the coupling member 22;

[0075] The venturi tube 23 has an escape area 24 . When the venturi tube 23 is placed in the installation cavity 11 , the step 12 is located in the escape area 24 .

[0076] The bracket 3 is installed in the avoidance area 24 so that the venturi tube 23 will not interfere with the anti-dry burning probe, the ignition needle and the thermocouple fixed on the bracket 3.

[0077] In this embodiment, if Figure 3 As shown, the Venturi tube 23 includes an upper tube 231 and a lower tube 232;

[0078] The lower pipe member 232 is fixedly mounted on the bottom of the coupling member 22, and a receiving cavity 233 is formed between the lower pipe member 232 and the coupling member 22;

[0079] The upper pipe member 231 is embedded in the accommodating cavity 233 and is installed in combination with the lower pipe member 232 .

[0080] One end of the existing Venturi tube is fixed to the bottom of the joint by screws and bolts. The sealing effect is determined by the screws and bolts. It is difficult to ensure that the Venturi tube will not leak after being fixed. It is also difficult to test. Even after using a seal, it is difficult to ensure that the screws and bolts will not leak after being tightened.

[0081] In this embodiment, the lower pipe 232 is integrally formed with the bottom of the coupling 22 , and the sealing effect can be conveniently adjusted by adjusting the upper pipe 231 , or a sealing member capable of providing sealing effect is provided between the upper pipe 231 or the lower pipe 232 .

[0082] In this embodiment, if Figure 3 to Figure 4 As shown, in order to make the gas intake smoother, the venturi tube 23 is provided with an intake pipe 234.

[0083] The air intake pipe 234 is extended obliquely, and one end of the air intake pipe 234 is connected to the fire cover 21;

[0084] One end of the air intake pipe 234 close to the fire cover 21 has an arc-shaped transition 2341 .

[0085] Compared with the angled setting at one end of the air intake pipe 234 , the arc-shaped transition 2341 can reduce the obstruction to the flow of gas and prevent the gas from being retained in the air intake pipe 234 for a long time.

[0086] According to the disclosure and teaching of the above description, those skilled in the art to which the present invention belongs may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the present invention.
