[0027] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0028] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0029] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0030] The embodiment of the utility model provides a nozzle mounting seat of an upper air inlet burner, such as Figure 1-3As shown, it includes a bottom plate 100, an air intake seat 200 and two nozzle columns 300. The air intake seat 200 is arranged on the bottom surface of the bottom plate 100, and the nozzle column 300 is arranged on the top surface of the bottom plate 100 and located above the air intake seat 200, which can facilitate the arrangement of the air intake channel below. The top of the nozzle column 300 is provided with a nozzle 310, and the nozzle 310 is used to spray gas outward. Two air intake channels 210 extending upward are arranged in the air intake seat 200, and the two air intake channels 210 are arranged and distributed along the first direction. The two air intake channels 210 extend to the tops of the two nozzle columns 300 respectively and are connected to the nozzle 310, and the gas in the air intake channel 210 can be sprayed outward through the nozzle 310. Air intake holes 220 extending along the first direction are arranged on both sides of the air intake seat 200, and the two air intake holes 220 are connected to the two air intake channels 210 respectively.

[0031] In this embodiment, the two air inlet holes 220 can supply air to the two air inlet channels 210 respectively. When the two air inlet channels 210 need to be connected, a hole can be opened on the inner wall of the air inlet channel 210 through any one of the air inlet holes 220 to open up the two air inlet channels 210, so that air can be supplied to the two air inlet channels 210 at the same time through any one of the air inlet holes 220. Therefore, the versatility of this embodiment is stronger. This structure is convenient for opening up the two air inlet channels 210, and for changing the air inlet structure, so as to flexibly configure a variety of air inlet methods. There is no need to open a mold to manufacture two sets of nozzle mounting seats, which can reduce the overall manufacturing cost. At the same time, air intake from the side of the air inlet seat 200 can reduce the bends of the air inlet pipe and facilitate the layout of the pipeline.

[0032] In some implementations, the two air inlet holes 220 can be coaxially arranged. After the two air inlet channels 210 are opened, the air flow can flow more easily into the air inlet channel 210 on the other side along the air inlet holes 220, which facilitates the flow of gas. Of course, the two air inlet holes 220 can also be non-coaxially arranged.

[0033] In some embodiments, Figure 5 As shown, the inner side wall of one of the air inlet channels 210 is provided with a connecting hole 230 penetrating to the other air inlet channel 210. A first blocking member 410 is provided in one of the air inlet holes 220 to seal it, and the other air inlet hole 220 is used for fuel gas input. Since the two air inlet channels 210 are connected through the connecting hole 230, gas can be supplied to the two air inlet channels 210 at the same time through one air inlet hole 220, which changes the original air inlet structure and realizes gas supply through one air inlet hole 220.

[0034] In this embodiment, a drilling tool such as a drilling machine can be used to extend into the air inlet hole 220 and then drill a hole along the first direction to open a connecting hole 230 , thereby facilitating the connection of the two air inlet channels 210 .

[0035] Furthermore, the first blocking member 410 is detachably fixed in the air inlet 220, and a detachable mounting structure is adopted to facilitate closing or opening the air inlet 220, which is easier to operate from Figure 4 The structure of the double air inlet 220 is changed to Figure 5 The air intake structure of the single air intake hole 220 is shown.

[0036] Furthermore, the first blocking member 410 is a screw, and the inner wall of the air inlet hole 220 provided with the first blocking member 410 is provided with a thread matched with the screw, so that the first blocking member 410 is detachably fixed in the air inlet hole 220 by means of a threaded connection.

[0037] In some embodiments, Figure 6 As shown, the inner side wall of one of the air inlet channels 210 is provided with a connecting hole penetrating to the other air inlet channel 210, and a second blocking member 420 is provided in the connecting hole to seal it.

[0038] For the air intake structure with a single air intake hole formed by opening a connecting hole, if it is desired to change it to the original air intake structure with two air intake holes, the second blocking member 420 can be used to block the connecting hole, and at the same time, the first blocking member 410 can be removed from the air intake hole 220, so that Figure 5 The structure of the single air inlet 220 shown is changed to Figure 6 The air intake structure of the double air intake holes 220 shown can flexibly change the air intake structure.

[0039] Furthermore, the second blocking member 420 may be made of a soft material such as rubber, which is inserted into the connection hole, fixed in the connection hole and blocks the connection hole at the same time.

[0040] In some embodiments, Figure 1 As shown, the spraying direction of the nozzle 310 may be parallel to the second direction, and the second direction may be perpendicular to the first direction.

[0041] In some embodiments, Figure 1 and Figure 2 As shown, protrusions 240 are provided on both sides of the air inlet seat 200, and the two air inlet holes 220 are respectively provided on the two protrusions 240, which can extend the length of the air inlet holes 220 and facilitate the connection of the external air inlet pipeline.

[0042] Furthermore, the unsealed air inlet 220 is connected to an air inlet connector 500. Figure 4 and Figure 6 As shown, when a dual air inlet structure is used, both air inlet holes 220 are not closed, and both air inlet holes 220 are connected to air inlet connectors 500; Figure 5As shown, when a single air inlet structure is used, one of the air inlet holes 220 is closed and the other is not closed, and the unclosed air inlet hole 220 is connected to an air inlet connector 500. An external air inlet pipeline can be connected to the air inlet connector 500 to transport the gas to the air inlet passage 210, and the external air inlet pipeline can be conveniently connected through the air inlet connector 500.

[0043] In this embodiment, the air inlet connector 500 may be provided with an external thread, and the inner wall of the air inlet hole 220 may be provided with a matching internal thread. The air inlet connector 500 is threadedly connected to the air inlet hole 220 to facilitate installation and disassembly.

[0044] In some embodiments, the air inlet passage 210 penetrates downward to the bottom surface of the air inlet seat 200 to form an opening on the bottom surface of the air inlet seat 200, and a third blocking member 430 is provided in the opening to seal it. When the air inlet passage 210 is formed, a hole can be formed upward from the bottom surface of the air inlet seat 200, so that the hole extends to the top of the nozzle column 300, so that the air inlet passage 210 is more easily formed.

[0045] In this embodiment, the third blocking member 430 may be a screw, and the inner wall of the opening is provided with a thread matching the screw, so that the third blocking member 430 closes the air inlet passage 210 by means of a threaded connection.

[0046] An embodiment of the utility model further provides a burner, comprising a nozzle mounting seat of an upper air inlet burner of any of the above embodiments. The specific description of the nozzle mounting seat of the upper air inlet burner can be referred to the above embodiments, which will not be repeated here.
