Description

Technical Field

[0001] This invention relates to the field of gas furnace technology, and in particular to a forced-air gas furnace. Background Technology

[0002] A forced-air gas stove is a gas stove equipped with a blower. The blower forces air into the intake pipe through a blower channel to increase the air intake, resulting in a stronger flame and a "stir-fry" function. Chinese-style gas stoves are divided into atmospheric and forced-air types. Forced-air stoves can be further classified by gas source: forced-air liquefied petroleum gas stoves, forced-air natural gas stoves, and forced-air manufactured gas stoves; by combustion method: forced-air post-mixed (air mixed during combustion) and forced-air pre-mixed (air mixed before combustion) gas stoves; and by application: forced-air Chinese-style gas wok stoves (also called "Chinese-style stoves"), forced-air gas steamers (where gas is used as an energy source, and forced-air oxygen is supplied for combustion to heat saturated steam for steaming food), forced-air gas low-soup stoves, and forced-air gas large pot stoves, etc.

[0003] Chinese Patent Publication No. CN115307187A discloses an air intake structure and a blower-type gas stove. The air intake structure includes a first gas pipeline, a first air intake pipe, a second air intake pipe, a blower pipe, and a blower. The first and second air intake pipes are coaxially arranged, with the outlet end of the first air intake pipe extending into the inner cavity of the second air intake pipe. An annular channel is provided between the outer side wall of the outlet end of the first air intake pipe and the inner side wall of the second air intake pipe, and the inner side wall of the inlet of the second air intake pipe and the outer side wall of the inlet of the first air intake pipe are sealed. The blower pipe is connected to the second air intake pipe, and a blower channel is provided inside the blower pipe. The blower is located at the inlet of the blower channel, and the outlet of the blower channel is connected to the annular channel. A return groove is provided on the side wall at the inlet of the first air intake pipe, with both ends of the return groove connected to the contraction cavity of the first air intake pipe and the blower channel, respectively. This invention can prevent gas backflow and leakage, thus improving the safety of blower-type gas stoves.

[0004] However, while the aforementioned forced-draft gas stove solves the problem of gas backflow and leakage, thus improving safety, it still suffers from burner clogging during use. Specifically, oil residue, rusty iron filings, and other debris from the bottom of the pot easily fall off and clog the vents of the forced-draft gas stove. Furthermore, cleaning from the outside makes it easier to push the residue back into the stove through the vents, affecting its performance. Summary of the Invention

[0005] Therefore, it is necessary to provide a blast gas stove to address the technical problem that residue at the bottom of the pot easily falls off and blocks the vent holes of the burner head of the blast gas stove, thus affecting the gas combustion performance during the use of the blast gas stove.

[0006] A forced-air gas stove includes: a burner head, on which a gas outlet cylinder is fixedly mounted; a sliding groove is provided on the upper surface of the gas outlet cylinder; a sliding tube is movably mounted on the gas outlet cylinder; a sliding ring is fixedly mounted on the bottom of the sliding tube and movably mounted with the sliding groove; an assembly tube is fixedly mounted on the top of the sliding tube; a top plate is fixedly mounted on the top of the assembly tube; multiple gas outlet holes are circumferentially arranged on the surface of the assembly tube; multiple gas supply holes are provided on the inner bottom surface of the gas outlet cylinder; an installation tube is fixedly mounted on the inner bottom surface of the gas outlet cylinder; the installation tube is located inside the gas supply holes; and a limit plate is movably mounted inside the installation tube. A guide rod is fixedly mounted on the mounting plate. The guide rod moves through the mounting tube and is fixedly mounted at the top and bottom of the top plate. A connecting plate is fixedly mounted on the guide rod, which is located above the mounting tube. A telescopic spring is mounted on the mounting tube and the guide rod. The two ends of the telescopic spring are fixedly mounted to the connecting plate and the inner bottom surface of the gas cylinder, respectively. Multiple sets of mounting plates are fixedly mounted on the surface of the connecting plate. Each set has two mounting plates. A connecting rod is fixedly mounted between the two mounting plates in each set. An adjusting rod is movably mounted on each connecting rod. A pointed cone is fixedly mounted on one end of each adjusting rod. The pointed cone moves over the gas outlet.

[0007] In one embodiment, each connecting rod is equipped with a torsion spring, the two ends of which are fixedly assembled with the mounting plate and the adjusting rod, respectively. Multiple support blocks are fixedly assembled on the surface of the connecting plate, and the support blocks are respectively attached to the bottom of the adjusting rod.

[0008] In one embodiment, a plurality of push rods are fixedly mounted on the inner bottom surface of the gas outlet cylinder. The push rods are located on the outside of the connecting plate, and the top of the push rods is in contact with the bottom of the adjusting rod.

[0009] In one embodiment, the guide rod has an inner cavity, and the surface of the guide rod has a plurality of moving grooves that communicate with the inner cavity, and the moving grooves and the inner cavity are located above the connecting plate.

[0010] In one embodiment, the surface of the top plate is provided with an operating groove, and a transmission screw is movably mounted on the inner cavity. One end of the transmission screw movably passes through the operating groove, and a knob is fixedly mounted on one end of the transmission screw, with the knob located in the operating groove.

[0011] In one embodiment, the surface of the knob is the same as the surface of the top plate.

[0012] In one embodiment, a threaded sleeve is threaded onto the transmission screw, and a sliding block is fixedly mounted on the threaded sleeve. The sliding block is movably assembled with the moving groove, and an inclined rod is fixedly mounted on one end of each sliding block, with the inclined rod positioned above the adjusting rod.

[0013] In one embodiment, an igniter is fixedly mounted on the burner head, the igniter is located on one side of the gas outlet cylinder, and a gas supply pipe is fixedly mounted on the burner head.

[0014] In one embodiment, a connecting block is fixedly mounted on the burner head, and the connecting block is provided with fixing holes.

[0015] In one embodiment, there are multiple cones, each of which is fixedly mounted to the end of the adjusting rod.

[0016] The aforementioned forced-air gas stove works by placing a pot on the burner head, ensuring the bottom of the pot is in contact with the top plate. The pot's weight causes the sliding ring on the sliding tube to slide in the sliding groove on the gas outlet cylinder. Simultaneously, one end of the guide rod moves inside the mounting tube. As the guide rod moves, the connecting plate causes the telescopic spring to contract. At this point, the push rod pushes the adjusting rod to move, and the adjusting rod rotates on the connecting rod. The torsion spring generates torque, and the pointed cone moves from the gas outlet hole to the inside of the mounting tube, facilitating gas flow. After the pot is used, the elastic force of the telescopic spring and the torque of the torsion spring cause the pointed cone to move into the gas outlet hole until the bottom of the adjusting rod is in contact with the support block. At this point, the pointed cone pushes the residue stuck in the gas outlet hole to the outside of the gas outlet cylinder, facilitating the cleaning of residue stuck in the gas outlet hole, improving the gas flow effect, and further enhancing the combustion performance of the gas during use.

[0032] For example, a forced-air gas stove includes: a burner head, on which a gas outlet cylinder is fixedly mounted; a sliding groove is provided on the upper surface of the gas outlet cylinder; a sliding tube is movably mounted on the gas outlet cylinder; a sliding ring is fixedly mounted on the bottom of the sliding tube, and the sliding ring is movably assembled with the sliding groove; an assembly tube is fixedly mounted on the top of the sliding tube; a top plate is fixedly mounted on the top of the assembly tube; multiple gas outlet holes are circumferentially arranged on the surface of the assembly tube; multiple gas supply holes are provided on the inner bottom surface of the gas outlet cylinder; an installation tube is fixedly mounted on the inner bottom surface of the gas outlet cylinder; the installation tube is located inside the gas supply holes; and a limit plate is movably mounted inside the installation tube. A guide rod is fixedly mounted on the top plate, passing through the mounting tube. The top of the guide rod is fixedly mounted to the bottom of the top plate. A connecting plate is fixedly mounted on the guide rod, located above the mounting tube. Telescopic springs are mounted on the mounting tube and the guide rod, with both ends of the springs fixedly mounted to the connecting plate and the inner bottom surface of the gas outlet cylinder, respectively. Multiple sets of mounting plates are fixedly mounted on the surface of the connecting plate, with two plates in each set. A connecting rod is fixedly mounted between the two mounting plates in each set. An adjusting rod is movably mounted on each connecting rod, with a pointed cone fixedly mounted at one end. The pointed cone moves across the gas outlet. A torsion spring is mounted on each connecting rod, with both ends fixedly mounted to the mounting plate and the adjusting rod, respectively. Multiple support blocks are fixedly mounted on the surface of the connecting plate, each supporting block fitting against the bottom of the adjusting rod. Multiple push rods are fixedly mounted on the inner bottom surface of the gas outlet cylinder, located outside the connecting plate, with the top of the push rod corresponding to the bottom of the adjusting rod. The guide rod has an internal cavity, and its surface has multiple moving grooves that communicate with the internal cavity, both located above the connecting plate. The top plate has an operating groove on its surface, and a transmission screw is movably mounted on the internal cavity. One end of the transmission screw extends through the operating groove, and a knob is fixedly mounted on the other end of the transmission screw, located within the operating groove. The knob's surface is flush with the top plate's surface. A threaded sleeve is threaded onto the transmission screw, and a sliding block is fixedly mounted on the threaded sleeve. The sliding block is movably mounted with the moving groove, and an inclined rod is fixedly mounted on one end of each sliding block, positioned above the adjusting rod. An igniter is fixedly mounted on the burner head, located on one side of the gas outlet cylinder. A gas supply pipe is fixedly mounted on the burner head. A connecting block with a fixing hole is fixedly mounted on the burner head. Multiple pointed cones are fixedly mounted on the ends of the adjusting rod.

[0033] The aforementioned forced-air gas stove works by placing a pot on the burner head, ensuring the bottom of the pot is in contact with the top plate. The pot's weight causes the sliding ring on the sliding tube to slide in the sliding groove on the gas outlet cylinder. Simultaneously, one end of the guide rod moves inside the mounting tube. As the guide rod moves, the connecting plate causes the telescopic spring to contract. At this point, the push rod pushes the adjusting rod to move, and the adjusting rod rotates on the connecting rod. The torsion spring generates torque, and the pointed cone moves from the gas outlet hole to the inside of the mounting tube, facilitating gas flow. After the pot is used, the elastic force of the telescopic spring and the torque of the torsion spring cause the pointed cone to move into the gas outlet hole until the bottom of the adjusting rod is in contact with the support block. At this point, the pointed cone pushes the residue stuck in the gas outlet hole to the outside of the gas outlet cylinder, facilitating the cleaning of residue stuck in the gas outlet hole, improving the gas flow effect, and further enhancing the combustion performance of the gas during use.

[0034] The following is in conjunction with the appendix Figures 1 to 8 This application will be described in further detail.

[0035] One embodiment of this application discloses a forced-air gas furnace; please refer to... Figures 1 to 4 A forced-air gas stove includes a burner head 500, on which a gas outlet cylinder 600 is fixedly mounted. A sliding groove 601 is provided on the upper surface of the gas outlet cylinder 600. A sliding tube 602 is movably mounted on the gas outlet cylinder 600. A sliding ring 607 that moves along the sliding groove 601 is fixedly mounted at the bottom of the sliding tube 602. An assembly tube 603 is fixedly mounted at the top of the sliding tube 602. A top plate 604 is fixedly mounted at the top of the assembly tube 603. Multiple gas outlet holes 605 are circumferentially arranged through the surface of the assembly tube 603.

[0036] The bottom surface of the gas burner cylinder 600 has multiple gas inlets 606. An installation tube 608 is fixedly mounted on the bottom surface of the gas burner cylinder 600. The installation tube 608 is located inside the gas inlets 606. A limiting plate 609 is movably mounted inside the installation tube 608. A guide rod 610 is fixedly mounted on the limiting plate 609. The guide rod 610 movably passes through the installation tube 608, and its top is fixedly mounted to the bottom of the top plate 604. A connecting plate 611 is fixedly mounted on the guide rod 610, and the connecting plate 611 is located above the installation tube 608.

[0037] A telescopic spring 612 is fixedly installed between the connecting plate 611 and the inner bottom surface of the gas outlet cylinder 600. The mounting tube 608 and the guide rod 610 are installed on the inner side of the telescopic spring 612. Multiple sets of mounting plates 613 are fixedly installed on the surface of the connecting plate 611. Each set of mounting plates 613 consists of two plates. A connecting rod 614 is fixedly installed between the two mounting plates 613 in each set. An adjusting rod 615 is movably installed on each connecting rod 614. A pointed cone 616 that moves on the gas outlet 605 is fixedly installed at one end of each adjusting rod 615.

[0038] Each connecting rod 614 is equipped with a torsion spring 617, and each assembly plate 613 has two torsion springs 617. The torsion springs 617 provide torque for the upward rotation of the adjusting rod 615 and act on the bottom of the adjusting rod 615. The two ends of the torsion springs 617 are fixedly assembled with the assembly plate 613 and the adjusting rod 615, respectively. Multiple support blocks 618 are fixedly assembled on the surface of the connecting plate 611, which fit against the bottom of the adjusting rod 615. The support blocks 618 can limit and support the movement of the adjusting rod 615. Multiple push rods 619 are fixedly assembled on the inner bottom surface of the gas stove cylinder 600, which fit against the bottom of the adjusting rod 615.

[0039] It should be noted that the push rod 619 is only located below the adjusting rod 615. It will only come into contact with the push rod 619 when the adjusting rod 615 and the connecting plate 611 move down. In essence, there is no connection between them, but they will resist the support when moving. Therefore, the term "fitting" is used to describe it, which can be understood as contact.

[0040] The push rod 619 is located outside the connecting plate 611 and inside the gas outlet cylinder 600. The number of gas outlet cylinders 600 is the same as that of the adjusting rod 615, and they are located below the adjusting rod 615. A vent hole 620 is provided on the surface of the mounting tube 608, and the vent hole 620 communicates with the interior of the mounting tube 608. When the pot is placed on the burner head 500, the bottom of the pot is placed against the top plate 604. The weight of the pot causes the sliding ring 607 on the sliding tube 602 to slide in the sliding groove 601 on the gas outlet cylinder 600. At the same time, one end of the guide rod 610 moves inside the mounting tube 608. As the guide rod 610 moves, the connecting plate 611 causes the telescopic spring 612 to retract. At this time, push rod 619 pushes adjusting rod 615 to move, adjusting rod 615 rotates on connecting rod 614, torsion spring 617 generates torque, and cone 616 moves from air outlet 605 to the inside of assembly tube 603 to facilitate air passage through air outlet 605. After the pot is used, under the elastic force of telescopic spring 612 and the torque of torsion spring 617, cone 616 moves into air outlet 605 until the bottom of adjusting rod 615 fits against support block 618. At this time, cone 616 pushes the residue stuck in air outlet 605 to the outside of gas cylinder 600, making it easier to clean the residue stuck in air outlet 605 and improve the ventilation effect.

[0041] Furthermore, there are multiple cones 616, which are fixedly mounted on the end of the adjusting rod 615. This can improve the efficiency of pushing out the residue stuck in the gas outlet 605 by using multiple cones 616, and the cone shape does not affect the output of the gas.

[0042] Please refer to Figures 5 to 8The guide rod 610 has an internal cavity 627, and its surface has multiple movable slots 623 communicating with the internal cavity 627. The movable slots 623 and the internal cavity 627 are located above the connecting plate 611. The surface of the top plate 604 has an operating slot 621, and a transmission screw 626 is movably mounted on the internal cavity 627. One end of the transmission screw 626 extends movably into the operating slot 621, and a knob 622 located in the operating slot 621 is fixedly mounted on the other end of the transmission screw 626. The surface of the knob 622 is flush with the surface of the top plate 604.

[0043] A threaded sleeve 628 is threaded onto the transmission screw 626, and a sliding block 624 that moves in the moving groove 623 is fixedly mounted on the threaded sleeve 628. An inclined rod 625 is fixedly mounted on one end of each sliding block 624, positioned above the adjusting rod 615. Twisting the knob 622 causes the transmission screw 626 to rotate on the threaded sleeve 628, moving the sliding block 624 in the moving groove 623. At this time, the inclined rod 625 clamps the adjusting rod 615, which is attached to the support block 618. Under the action of the support block 618, the torsion spring 617 cannot deflect downwards; under the power of the push rod 619 and the gas, it can only tilt upwards, resulting in upward deformation, ultimately causing the cone 616 to be out of place in the adjusting rod 615. Now the tilting rod 625 moves downward, causing the tilting rod 625 to drive the adjusting rod 615 downward, reducing the deformation of the torsion spring 617, helping the torsion spring 617 to recover, avoiding the deformation of the torsion spring 617 from affecting the performance of the cone 616 on the adjusting rod 615, and improving the service life of the torsion spring 617.

[0044] Please refer to this again. Figure 1 An igniter 100 is fixedly mounted on the burner head 500. The igniter 100 is located on one side of the gas outlet cylinder 600. A gas supply pipe 400 is fixedly mounted on the burner head 500. A connecting block 300 is fixedly mounted on the burner head 500. The connecting block 300 is provided with a fixing hole 200. The burner head 500 is fixed by mounting bolts through the fixing holes 200 on the connecting block 300. In use, the gas flows through the gas supply pipe 400 and is then sprayed out through the gas supply hole 606 and the gas outlet hole 605, and is ignited by the igniter 100.

[0045] The working principle of the above embodiment is as follows: The pot is placed on the burner head 500, so that the bottom of the pot is in contact with the top plate 604. The weight of the pot causes the sliding ring 607 on the sliding tube 602 to slide in the sliding groove 601 on the gas outlet cylinder 600. Simultaneously, one end of the guide rod 610 moves inside the mounting tube 608. As the guide rod 610 moves, the connecting plate 611 causes the telescopic spring 612 to retract. At this time, the push rod 619 pushes the adjusting rod 615 to move. The adjusting rod 615 rotates on the connecting rod 614, and the torsion spring 617 generates torque. The pointed cone 616 moves from the gas outlet 605 to the inside of the mounting tube 603, facilitating the passage of gas through the gas outlet 605. After the pot is used, under the elastic force of the telescopic spring 612 and the torque of the torsion spring 617, the pointed cone 616 moves towards the gas outlet. The adjusting rod 615 moves within the hole 605 until its bottom contacts the support block 618. At this point, the cone 616 pushes the residue stuck in the gas outlet 605 to the outside of the gas cylinder 600, facilitating the cleaning of the residue stuck in the gas outlet 605 and improving the ventilation effect. To prevent the torsion spring 617 from deforming due to the force of the push rod 619 for a long time, thus affecting its service life, the knob 622 is turned, causing the transmission screw 626 to rotate on the threaded sleeve 628, allowing the sliding block 624 to move on the moving groove 623. At this time, the tilting rod 625 clamps the adjusting rod 615 that is in contact with the support block 618, preventing the deformation of the torsion spring 617 from affecting the performance of the cone 616 on the adjusting rod 615, improving the service life of the torsion spring 617, and reducing the cost of use.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
