Description

Technical Field

In the process of implementing the scheme, the invention found that the following problems in the prior art have not been well solved: 1. Since the existing burner can only control the number of ignition heads on the burner by adjusting the size of the gas valve during use, the fire heads are still relatively concentrated in the middle position of the burner, and it is difficult to adjust the position of the fire heads, which easily affects the uniformity of heating the bottom of the pot; 2. Usually, during the use of the burner of the gas stove, air is quantitatively input into the position of the fire head through the air port, and the amount of air input by the air port remains unchanged during the process of adjusting the size of the burner. When the oxygen content in the air is too large or too small, the natural gas combustion efficiency will be affected. When some existing burners are used, it is difficult to synchronously adjust the air delivery volume during the process of adjusting the size of the fire, which is easy to cause waste.

[0020] A method for using a burner for a gas stove comprises the following steps:

[0021] S1. When adjusting the size of the burner, first turn the regulating switch to operate the natural gas regulating valve to control the amount of natural gas delivered by the natural gas regulating valve. During this process, the regulating switch engages the regulating gear with the gear rod, so that the gear rod engages with the end face gear ring on the regulating tube for transmission. At this time, the regulating tube rotates synchronously with the regulating disk. During the rotation of the regulating disk, the distance between the distributor head and the main fire head is adjusted by sliding on the surface of the supporting disk through the adjustment groove and the sliding pin at the bottom of the distributor head. In this way, the position of the distributor head can be adjusted synchronously during the adjustment of the natural gas regulating valve, so that when the burner is adjusted to a high fire, the six distributor heads move in opposite directions, and when the burner is adjusted to a low fire, the six distributor heads move relative to each other;

[0022] S2. During the rotation of the adjusting disk, the adjusting disk rotates synchronously with the adjusting rod, so that the adjusting rod slides along the surface of the arc-shaped inclined groove at the side wall of the arc-shaped adjusting plate. At this time, the arc-shaped adjusting plate moves downward and moves downward synchronously with the three rod-shaped mounting brackets, so that the rod-shaped mounting brackets move with the adjusting cylinder at the corresponding gas filling hole position, change the gap exposed by the gas filling hole, and control the size of the gas filling amount of the gas filling hole. Moreover, since the rotation of the adjusting disk is synchronized with the rotation of the natural gas regulating valve, when the switch of the natural gas regulating valve is increased, the rotation amplitude of the adjusting disk is synchronously increased, so that the adjusting rod and the arc-shaped inclined groove cooperate to increase the distance that the arc-shaped adjusting plate moves downward, thereby increasing the gap exposed by the gas filling hole. Conversely, the adjustment amplitude of the natural gas regulating valve is small, and the gap exposed by the gas filling hole is reduced.

[0023] S3. While the rod-shaped mounting bracket is moving the adjusting cylinder downward, the piston rod inside the adjusting cylinder slides in cooperation with the surface of the guide bracket through the guide pin, so that the piston rod moves inside the adjusting cylinder. During the use of the burner, the high temperature causes the memory metal to deform and move the limit rod downward and insert it into the limit hole at the top of the piston rod, thereby limiting the piston rod in one direction. When the burner is stopped, the adjusting cylinder rises and resets and seals one end of the air supply hole. After the memory metal cools and recovers, it rises and resets with the limit rod. Under the elastic recovery of the compression spring, the piston rod moves toward the air supply hole. At this time, during the resetting process of the piston rod, air is discharged from the other end of the air supply hole to clean the inside of the air supply hole.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] In the present invention, by using the adjusting switch, the adjusting disk and the fire head adjusting mechanism in coordination, when the adjusting switch is turned to operate the natural gas regulating valve to adjust the firepower of the burner, the distances between the six fire heads can be adjusted synchronously under the action of the fire head adjusting mechanism, so that when the burner is turned on with high firepower, the six fire heads are away from the main fire head, thereby ensuring the uniformity of heating the bottom of the pot.

[0026] In the present invention, through the coordinated use of components such as the adjustment disk, the fire head adjustment mechanism and the airflow adjustment mechanism, when the adjustment switch is turned to adjust the firepower of the burner, during the coordinated use of the firepower adjustment mechanism and the airflow adjustment mechanism, the gap adjustment between the adjustment cylinder and the air supply hole can be carried out synchronously with the adjustment of the firepower size, so that when the burner is turned on with high firepower, the gap between the adjustment cylinder and the air supply hole increases, thereby ensuring that the ratio of natural gas to oxygen in the air is in an efficient combustion state during the combustion process, thereby improving the energy-saving effect of the burner.

[0027] In the present invention, through the coordinated use of components such as the adjustment disk, the adjustment switch and the airflow adjustment mechanism, when the adjustment switch is turned to operate synchronously with the airflow adjustment mechanism, the piston rod inside the adjustment cylinder can move and accumulate force. After the burner stops using, the airflow generated by the piston rod during the resetting process automatically cleans the inside of the air supply hole, thereby avoiding blockage of the air supply hole position of the burner during long-term use and affecting the use effect.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

It should be noted that a cross-shaped mounting groove matching the natural gas regulating valve 701 is provided inside the gas stove bracket 1, and the bottom of the natural gas regulating valve 701 is connected to the external natural gas pipe. The natural gas regulating valve 701 here is a prior art and will not be described in detail here.

[0042] The inner top surface of the gas stove support 1 is fixedly connected with a support bar 703, the upper part of the support bar 703 is rotatably connected with a gear rod 704, one end of the gear rod 704 is meshed with the surface of the adjustment gear 702, the middle part of the adjustment disk 5 is fixedly connected with an adjustment tube 705, the surface of the adjustment tube 705 is rotatably connected to the middle position of the partition 4, the lower part of the adjustment tube 705 penetrates the partition 4 and is fixedly sleeved with an end face toothed ring 706, and the other end of the gear rod 704 is meshed with the bottom of the adjacent end face toothed ring 706. It should be noted that: the surface of the support bar 703 is fixedly connected with a connecting bearing, the middle part of the gear rod 704 is fixedly connected with the inner ring of the connecting bearing; a circular hole is opened in the middle position of the partition 4, the inner wall of the circular hole is fixedly connected with a supporting bearing, and the adjusting tube 705 is fixedly connected inside the supporting bearing; and a through hole matching with the adjusting tube 705 is opened in the middle part of the adjusting disk 5, so that the upper part of the adjusting tube 705 is fixedly installed inside the through hole.

[0043] One end of the natural gas regulating valve 701 away from the regulating switch 6 is fixedly connected to a gas pipe 707, and one end of the gas pipe 707 passes through the regulating pipe 705 and is fixedly connected to a support plate 708. The support plate 708 is arranged above the regulating plate 5, and the side wall of the support plate 708 is fixedly connected to the inner wall of the support cover 3.

[0044] A main fire head 709 is fixedly connected to the middle position of the top of the support plate 708, the bottom of the main fire head 709 is fixedly connected to the top of the gas pipe 707, the upper part of the gas pipe 707 is fixedly connected to a diverter sleeve 710, the surface of the diverter sleeve 710 is fixedly connected to six diverter pipes 711 at equal intervals along the circumference, and the surface of the support plate 708 is slidably connected to six diverter heads 712 at equal intervals along the circumference, the six diverter heads 712 correspond to the six diverter pipes 711 one by one, one end of the diverter pipe 711 is fixedly connected to the surface of the corresponding diverter head 712, and a sliding pin 713 is fixedly connected to the bottom of the diverter head 712. It should be noted that the diverter pipe 711 is set as a metal hose, and the surface of the metal hose is provided with a heat insulation layer to prevent high temperature from affecting the service life.

[0045] The surface of the adjusting disk 5 is provided with six adjusting grooves 714 equidistantly along the circumference, and the six adjusting grooves 714 correspond to the six sliding pins 713 one by one, and the lower part of the sliding pin 713 is slidably connected to the inside of the corresponding adjusting grooves 714. It should be noted that when the adjusting switch 6 is turned, the adjusting tube 705 and the supporting disk 708 are synchronously rotated with the rotation of the adjusting switch 6 through the coordinated transmission of the gear rod 704, the adjusting gear 702 and the end face gear ring 706. At this time, the positions of the six ignition heads 712 on the supporting disk 708 can be synchronously adjusted. When the adjusting switch 6 is adjusted to a high fire, the six ignition heads 712 move back to back, increase the distance between them, and effectively ensure the uniformity of heating the bottom of the pot. On the contrary, when the fire is adjusted to a low fire, the six ignition heads 712 move relatively.

[0046] In this embodiment, Figures 1 to 9 As shown, the side wall of the support plate 708 is symmetrically fixedly connected with a connecting rod, and one end of the connecting rod is fixedly connected to the inner wall of the support cover 3.

[0047] The surface of the support plate 708 is provided with six rectangular grooves equidistantly along the circumference, and a rectangular block is fixedly connected to the middle of the ignition head 712, and the ignition head 712 is slidably connected to the inside of the corresponding rectangular groove through the rectangular block. It should be noted that: a moving groove is provided on both sides of the inner wall of the rectangular groove, and a moving block is fixedly connected to both sides of the rectangular block, and the moving block is slidably connected to the inside of the corresponding moving groove, and the stability of the rectangular block during the sliding process inside the rectangular groove is ensured by the cooperation between the moving groove and the moving block.

[0048] In this embodiment, Figures 1 to 9 As shown, the airflow adjustment mechanism 8 includes adjustment rods 801 , and the number of the adjustment rods 801 is four. The four adjustment rods 801 are fixedly connected to the four sides of the adjustment disk 5 at equal intervals along the circumference.

[0049] The inner wall of the support cover 3 is fixedly connected with a support block 802, and the support blocks 802 are arranged in twelve numbers, and every three support blocks 802 are arranged in a group, and the four groups of support blocks 802 correspond to the four adjustment rods 801 one by one, and the middle part of the support block 802 is vertically slidably connected with a rod-shaped mounting frame 803, and an arc-shaped adjustment plate 804 is fixedly connected between the bottoms of the three adjacent rod-shaped mounting frames 803, and the side wall of the arc-shaped adjustment plate 804 is provided with an arc-shaped inclined groove 805, and one end of the adjustment rod 801 is slidably connected to the inside of the corresponding arc-shaped inclined groove 805. It should be noted that: one end of the adjusting rod 801 is set to be spherical, so as to reduce the friction resistance generated between the adjusting rod 801 and the inner wall of the arc-shaped inclined groove 805; when the adjusting disk 5 rotates and adjusts the distance between the six ignition heads 712, the adjusting disk 5 carries the adjusting rod 801 to slide inside the arc-shaped inclined groove 805 on the side wall of the arc-shaped adjusting plate 804, so that the arc-shaped adjusting plate 804 moves toward the top of the partition 4, and the greater the angle of rotation of the adjusting disk 5, the longer the distance the arc-shaped adjusting plate 804 moves downward; the rotation distance of the adjusting disk 5 is consistent with the length of the arc-shaped inclined groove 805, so as to prevent the adjusting rod 801 from moving out from the inside of the arc-shaped inclined groove 805.

[0050] The upper part of the rod-shaped mounting frame 803 is fixedly connected with an adjustment cylinder 806, the interior of the adjustment cylinder 806 is slidably connected with a piston rod 807, a compression spring 808 is movably connected between the inner wall of the adjustment cylinder 806 and the side wall of the piston rod 807, one end of the piston rod 807 passes through the adjustment cylinder 806 and is fixedly connected with a guide pin 809, and the inner wall of the support cover 3 is fixedly connected with a guide bracket 810 that matches the guide pin 809. It should be noted that: during the process of adjusting the high fire of the burner, the arc-shaped adjustment plate 804 moves downward with the operation and the rod-shaped mounting frame 803 and the adjustment cylinder 806, so that the gap between the adjustment cylinder 806 and the air supply hole 816 increases, and the air supply effect is improved. In this process, when the piston rod 807 moves downward with the adjustment cylinder 806, the guide pin 809 at the end of the piston rod 807 slides with the surface of the guide bracket 810, so that the piston rod 807 moves toward the inside of the adjustment cylinder 806 and squeezes the compression spring 808 to store force.

[0051] Five limit holes 811 are equidistantly provided on the top of the piston rod 807, a protective cover 812 is fixedly connected to the side of the adjusting cylinder 806 away from the support cover 3, a memory metal 813 is fixedly connected to the inner top surface of the protective cover 812, an extrusion spring 814 is fixedly connected between the bottom of the memory metal 813 and the inner top surface of the protective cover 812, a limit rod 815 matched with the limit hole 811 is fixedly connected to the middle position of the bottom of the memory metal 813, and an air replenishing hole 816 matched with the adjusting cylinder 806 is provided on the side wall of the upper part of the protective cover 812. It should be noted that: when the burner is ignited and used, the memory metal 813 is deformed in a high temperature environment and moves the limit rod 815 downward, so that the limit rod 815 is inserted into the inside of the limit hole 811, and the movement of the piston rod 807 is limited. When the burner stops being used, the memory metal 813 recovers its deformation after cooling down, and is reset under the action of the extrusion spring 814, so that the limit rod 815 rises and releases the connection with the limit hole 811, and then the compression spring 808 elastically recovers and resets the piston rod 807, and the airflow pushed out by the piston rod 807 is discharged from the upper end position of the air supply hole 816 to clean the inside of the air supply hole 816; the elastic force of the extrusion spring 814 here is relatively small, and it is only used to assist the memory metal 813 in recovering its deformation. The memory metal 813 is a prior art and will not be described in detail here.

[0052] In this embodiment, Figures 1 to 9 As shown, the guide bracket 810 is composed of an arc rod and a Z-shaped bar, one end of the arc rod is fixedly connected to the inner wall of the support cover 3, the other end of the arc rod is fixedly connected to the side wall of the Z-shaped bar, and the surface of the guide pin 809 overlaps the surface of the Z-shaped bar. It should be noted that when the adjustment cylinder 806 moves downward, the guide pin 809 on the piston rod 807 inside the adjustment cylinder 806 slides along the inclined track of the Z-shaped bar, so that the piston rod 807 moves inside the adjustment cylinder 806.

[0053] In this embodiment, Figures 1 to 9 As shown, a plug hole is provided at one end of the regulating cylinder 806 away from the air supply hole 816, and the piston rod 807 is movably inserted into the inside of the plug hole, and a positioning block is fixedly connected to the inner wall of the plug hole, and a positioning groove is provided at the bottom of the piston rod 807, and the positioning block is slidably connected to the inside of the positioning groove. It should be noted that the sliding cooperation between the positioning groove and the positioning block can prevent the piston rod 807 from rotating inside the regulating cylinder 806, which affects the cooperation between the limiting hole 811 and the limiting rod 815.

[0054] In this embodiment, Figures 1 to 9As shown, the upper part of the limit hole 811 is set to be conical, and the lower part of the limit rod 815 is provided with a chamfer that matches the limit hole 811, and the limit rod 815 is set to be a telescopic rod. It should be noted that: through the setting of the limit rod 815 of the telescopic rod structure, when the piston rod 807 moves toward the axial direction of the support cover 3, the chamfer at the lower part of the limit rod 815 can be retracted and raised after being pressed by the inner wall of the limit hole 811, and the piston rod 807 will be limited by the side of the limit rod 815 that is not chamfered during the reverse movement, so that the limit rod 815 can unidirectionally limit the movement of the piston rod 807; and the limit rod 815 can only slide vertically inside the protective cover 812, and cannot rotate.

[0055] In this embodiment, Figures 1 to 9 As shown, a method for using a burner for a gas stove comprises the following steps:

[0056] S1. When adjusting the size of the burner, firstly, the regulating switch 6 is turned to operate the natural gas regulating valve 701 to control the size of the natural gas delivered by the natural gas regulating valve 701. During this process, the regulating switch 6 engages the regulating gear 702 with the gear rod 704, so that the gear rod 704 engages with the end face gear ring 706 on the regulating tube 705 for transmission. At this time, the regulating tube 705 rotates synchronously with the regulating disk 5. During the rotation of the regulating disk 5, the regulating slot 714 cooperates with the sliding pin 713 at the bottom of the ignition head 712 to slide on the surface of the support disk 708 to adjust the distance between the ignition head 712 and the main fire head 709. In this way, the position of the ignition head 712 can be adjusted synchronously during the adjustment of the natural gas regulating valve 701. When the burner is adjusted to a high fire, the six ignition heads 712 move in opposite directions to ensure the uniform heating of the pot bottom under the high fire state. When the burner is adjusted to a low fire, the six ignition heads 712 move relatively.

[0057] S2. During the rotation of the adjusting disk 5, the adjusting disk 5 rotates synchronously with the adjusting rod 801, so that the adjusting rod 801 slides along the surface of the arc-shaped inclined groove 805 at the side wall position of the arc-shaped adjusting plate 804. At this time, the arc-shaped adjusting plate 804 moves downward and moves downward synchronously with the three rod-shaped mounting brackets 803, so that the rod-shaped mounting brackets 803 move with the adjusting cylinder 806 at the corresponding position of the gas supplement hole 816, change the gap exposed by the gas supplement hole 816, and control the size of the gas supplement amount of the gas supplement hole 816. Since the rotation of the adjusting disk 5 is synchronized with the rotation of the natural gas regulating valve 701, when the switch of the natural gas regulating valve 701 is increased, the rotation amplitude of the adjusting disk 5 is synchronously increased, so that the adjusting rod 801 and the arc-shaped inclined groove 805 cooperate to increase the downward distance of the arc-shaped adjusting plate 804, thereby increasing the gap exposed by the gas supplement hole 816. On the contrary, the adjustment amplitude of the natural gas regulating valve 701 is small, and the gap exposed by the gas supplement hole 816 is reduced.

[0058] S3. During the process of the rod-shaped mounting frame 803 moving the adjusting cylinder 806 downward, the piston rod 807 inside the adjusting cylinder 806 slides in cooperation with the surface of the guide bracket 810 through the guide pin 809, so that the piston rod 807 moves inside the adjusting cylinder 806. During the use of the burner, the high temperature causes the memory metal 813 to deform and move the limiting rod 815 downward to be inserted into the limiting hole 811 at the top of the piston rod 807, thereby limiting the piston rod 807 in one direction. When the burner stops being used, the adjusting cylinder 806 rises and resets and seals one end of the air supply hole 816. After the memory metal 813 cools and recovers, it rises and resets with the limiting rod 815. Under the elastic recovery of the compression spring 808, the piston rod 807 moves toward the direction of the air supply hole 816. At this time, during the resetting process of the piston rod 807, the air flow is discharged from the other end of the air supply hole 816 to clean the inside of the air supply hole 816 to avoid blockage of the air supply hole 816.

8. A method for using a burner for a gas stove, characterized in that: Using a burner for a gas stove as claimed in any one of claims 1 to 7 comprises the following steps: S1. When adjusting the size of the burner, the regulating switch (6) is first turned to drive the natural gas regulating valve (701) to operate, thereby controlling the amount of natural gas delivered by the natural gas regulating valve (701). During this process, the regulating switch (6) drives the regulating gear (702) to mesh with the gear rod (704), so that the gear rod (704) and the end face gear ring (706) on the regulating tube (705) are meshed and transmitted. At this time, the regulating tube (705) drives the regulating disk (5) to rotate synchronously. When the regulating disk (5) rotates, During the adjustment process, the adjustment groove (714) and the sliding pin (713) at the bottom of the ignition head (712) are matched and slid, so that the ignition head (712) slides on the surface of the support plate (708) to adjust the distance between the ignition head (712) and the main ignition head (709), so that the position of the ignition head (712) can be adjusted synchronously during the adjustment process of the natural gas regulating valve (701), so that when the burner is adjusted to a high flame, the six ignition heads (712) move in opposite directions, and when the burner is adjusted to a low flame, the six ignition heads (712) move relatively; S2. During the rotation of the adjusting disk (5), the adjusting disk (5) rotates synchronously with the adjusting rod (801), so that the adjusting rod (801) slides along the surface of the arc-shaped inclined groove (805) at the side wall of the arc-shaped adjusting plate (804). At this time, the arc-shaped adjusting plate (804) moves downward and synchronously moves downward with the three rod-shaped mounting frames (803), so that the rod-shaped mounting frames (803) move with the adjusting cylinder (806) at the corresponding position of the air supply hole (816), thereby changing the gap exposed by the air supply hole (816) and controlling the air supply. The gas supply amount of the gas supply hole (816) is controlled by the adjusting disk (5). Since the rotation of the adjusting disk (5) is synchronized with the rotation of the natural gas regulating valve (701), when the switch of the natural gas regulating valve (701) is increased, the rotation amplitude of the adjusting disk (5) is synchronously increased, so that the adjustment rod (801) and the arc-shaped inclined groove (805) cooperate to move the arc-shaped adjusting plate (804) downward to increase the distance, thereby increasing the gap exposed by the gas supply hole (816). On the contrary, when the adjustment amplitude of the natural gas regulating valve (701) is small, the gap exposed by the gas supply hole (816) is reduced. S3. When the rod-shaped mounting frame (803) moves the adjusting cylinder (806) downward, the piston rod (807) inside the adjusting cylinder (806) slides with the surface of the guide bracket (810) through the guide pin (809), so that the piston rod (807) moves inside the adjusting cylinder (806). During the use of the burner, the high temperature causes the memory metal (813) to deform and move the limiting rod (815) downward to be inserted into the limiting hole (811) at the top of the piston rod (807), thereby pressing the piston rod (807). 07) is used for one-way limiting. When the burner stops being used, the regulating cylinder (806) rises and resets and seals one end of the air supply hole (816). After the memory metal (813) cools and recovers, it rises and resets with the limiting rod (815). Under the elastic recovery of the compression spring (808), the piston rod (807) moves toward the air supply hole (816). At this time, during the resetting process of the piston rod (807), the air flow is discharged from the other end of the air supply hole (816) to clean the inside of the air supply hole (816).
