[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0029] Combined with Figures 1-6 , a device for adjusting the outlet speed of a burner, including a primary control room 1 and a secondary control room 2 arranged on one side of the primary control room 1. A heat dissipation box 11 is fixedly connected to the bottom of the primary control room 1, a first connecting pipe 12 is fixedly connected to the inside of the primary control room 1, and an adjustment mechanism is arranged in the primary control room 1. The adjustment mechanism plays the effect of adjusting the gas flow rate. The adjustment mechanism includes a motor 111 fixedly connected inside the heat dissipation box 11, a ball valve 121 rotatably connected inside the first connecting pipe 12, a first knob 13 rotatably connected to the other side of the primary control room 1, a connecting box body 14 fixedly connected to one side of the secondary control room 2, and a sealing ring 141 fixedly connected to the inside of the connecting box body 14.

[0030] Next, the present invention will be further described in conjunction with the embodiments.

[0031] Embodiment 1: To solve the problem that in the existing outlet speed adjustment device during use, it is often carried out through a single manual control. When the adjustment device is installed at a high place, it is difficult for the staff to adjust the gas flow rate, affecting the use effect. The following technical solutions are disclosed in this embodiment, specifically as Figures 1-5As shown in the figure, the output end of the motor 111 is fixedly connected with a first transmission gear 112. One side of the first transmission gear 112 is meshed and connected with a second transmission gear 113. The bottom end of the ball valve 121 extends to the outside of the first connecting pipe 12 and is fixedly connected with a three-quarter circle block 122. The bottom of the first connecting pipe 12 is fixedly connected with a fixed disk 123. The bottom of the fixed disk 123 is fixedly connected with a baffle 124. The baffle 124 is matched with the three-quarter circle block 122. One end of the first knob 13 extends into the interior of the first control room 1 and is fixedly connected with a first bevel gear 131. One side of the first bevel gear 131 is meshed and connected with a second bevel gear 132. The second bevel gear 132 is located above the first connecting pipe 12. The bottom end of the second bevel gear 132 is fixedly connected with the ball valve 121. When in use, when it is necessary to control the gas flow rate of the burner, the motor 111 located inside the heat dissipation box 11 can be started at this time. The motor 111 drives the first transmission gear 112 to rotate, and then the second transmission gear 113 rotates. The second transmission gear 113 drives the three-quarter circle block 122 to rotate, and then the ball valve 121 rotates inside the first connecting pipe 12. The rotation of the ball valve 121 can adjust the gas flow rate passing through the first connecting pipe 12. When the motor 111 is started and adjusted, the settings of the three-quarter circle block 122 and the baffle 124 can make the ball valve 121 only rotate within a certain range, preventing the ball valve 121 from changing from the open state to the closed state due to multiple starts of the motor 111. When manual adjustment is required, the first knob 13 located on one side of the first control room 1 can be rotated at this time. The first knob 13 drives the first bevel gear 131 to rotate, and then the second bevel gear 132 rotates. The second bevel gear 132 can also make the ball valve 121 rotate inside the first connecting pipe 12, and then the gas flow rate passing through the first control room 1 can be adjusted, and then the gas flow rate of the gas-air mixture can be controlled. The function of enabling the staff to conveniently adjust the gas flow rate according to actual needs is realized, and the use effect is improved.

[0032] Embodiment 2: To solve the problem that the existing outlet speed regulating devices are often relatively single in function, and when related devices are damaged, it is not convenient to maintain the damaged devices, which in turn affects the subsequent work efficiency. The following technical solutions are disclosed in this embodiment, specifically as Figures 6-10As shown, a moving block 142 is slidably connected to the bottom of the connecting box body 14. The top of the moving block 142 extends into the connecting box body 14 and is fixedly connected to a first spring rod 143. One end of the first spring rod 143 is fixedly connected to a first clamping hoop 144. A second spring rod 145 is also fixedly connected inside the connecting box body 14. The bottom of the second spring rod 145 is fixedly connected to a second clamping hoop 146. The second clamping hoop 146 is located above the two first clamping hoops 144. A second connecting pipe 15 is slidably connected to the other side of the first control room 1. The second connecting pipe 15 is communicated with the first connecting pipe 12 through a hose. A second knob 151 is rotatably connected to the bottom of the first control room 1. The top of the second knob 151 is fixedly connected to a screw rod 152. The screw rod 152 is threadedly connected to the second connecting pipe 15. The second connecting pipe 15 is matched with the sealing ring 141. The second connecting pipe 15 is slidably engaged with the first clamping hoop 144 and the second clamping hoop 146. An installation groove 21 is formed on one side of the connecting box body 14. A bolt 211 is disposed through the outside of the first control room 1. A clamping block 212 is also fixedly connected to the other side of the first control room 1. The clamping block 212 is slidably engaged with the installation groove 21. The bolt 211 is matched with the clamping block 212. A protective cover 3 is detachably disposed at one end of the first connecting pipe 12. A handle 31 is fixedly connected to one side of the protective cover 3. A pressing block 32 is slidably connected inside the handle 31. One end of the pressing block 32 is fixedly connected to a third spring rod 321. One end of the third spring rod 321 is fixedly connected inside the handle 31. Connecting rods 322 are fixedly connected to both the left and right ends of the pressing block 32. One end of the connecting rod 322 is slidably connected to a trapezoidal block 323. The trapezoidal block 323 is slidably connected inside the protective cover 3. Fixing grooves 325 are formed inside the first connecting pipe 12. There are two groups of fixing grooves 325. The fixing grooves 325 are slidably engaged with fixing blocks 324. When it is necessary to remove the first control room 1 for maintenance operations, the bolt 211 located on the connecting box body 14 can be rotated first. After the bolt 211 is separated from the clamping block 212, the moving block 142 located at the bottom of the connecting box body 14 can be pulled first. The moving block 142 drives the first clamping hoop 144 to move, so that the first clamping hoop 144 loosens the clamping of the second connecting pipe 15. At this time, the second connecting pipe 15 can be removed from the inside of the connecting box body 14, and then the first control room 1 and the second control room 2 can be separated. When the maintenance operation is completed and the first control room 1 needs to be installed, the first control room 1 can be moved to one side of the second control room 2, so that the second connecting pipe 15 moves to the opening on the connecting box body 14. Then, the second connecting pipe 15 located at the bottom of the first control room 1 is rotated. The second connecting pipe 15 drives the second knob 151 to rotate, so that the screw rod 152 moves. When the screw rod 152 moves to the intersection of the two first clamping hoops 144, due to the setting of the rounded edge at the bottom end of the first clamping hoop 144, the second connecting pipe 15 can move between the two first clamping hoops 144. Under the action of the first spring rod 143, the first clamping hoop 144 can clamp the second connecting pipe 15.Moreover, the arrangement of the second spring rod 145 and the second clamping hoop 146 can achieve the effect of clamping the second connecting pipe 15 in all directions. At the same time, the clamping block 212 moves into the interior of the installation groove 21. Finally, the bolt 211 is rotated, and the bolt 211 can fix the clamping block 212, thereby preventing the second control room 2 from detaching from the first control room 1. And when the first control room 1 is not in use, the protective cover 3 can be placed on one side of the first connecting pipe 12 on the first control room 1. After the protective cover 3 is installed inside the first connecting pipe 12, due to the arrangement of the fixing block 324, the fixing block 324 can automatically engage in the fixing groove 325, thereby fixing the protective cover 3. When the first control room 1 needs to be used, the staff can hold the handle 31. During the pulling process, the pressing block 32 is pressed. The pressing block 32 drives the two connecting rods 322 to move, so that the two trapezoidal blocks 323 slide inside the protective cover 3. The trapezoidal block 323 drives the fixing block 324 to disengage from the interior of the fixing groove 325, and thus the protective cover 3 can be removed from one side of the first connecting pipe 12, which can improve the service life of the first control room 1, realize the function of improving the work efficiency of disassembling and assembling the first control room 1, and at the same time improve the service life of the first control room 1.
