Description

Technical Field

[0001] The invention relates to the technical field of burners, in particular to a stove burner with an external fire starter. Background Art

[0002] The stove burner is the core component of a gas stove. Its main function is to mix fuel (such as natural gas, liquefied petroleum gas, etc.) with air and ignite it to produce a flame, thereby achieving the purpose of cooking food. When igniting the stove, an ignition device is required. Traditional ignition devices are divided into external ignition devices and built-in ignition devices according to different installation locations. Among them, external ignition devices are easier to replace and are less susceptible to oil pollution than built-in ignition devices. Traditional external ignition devices are composed of a mounting base, an ignition column and an induction column. Among them, the mounting base, ignition column and induction column are mostly made of metal. Then, after long-term use, the metal will be damaged by thermal expansion and contraction, eventually causing the ignition column to leak or discharge abnormally. Moreover, when the ignition column leaks or discharges abnormally, since the ignition column is always in an energized state, it will cause the ignition column to explode, or even cause the stove to explode, ultimately causing personal injury to the cook.

[0032] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] refer to Figures 1 to 15 The stove burner with an external fire type shown in the figure includes a stove body 1 and an ignition assembly. The stove body 1 is cylindrical. The ignition assembly is arranged on the outer wall of the stove body 1. The ignition assembly includes a ceramic shell 2, an ignition column 3 and an induction column 4. The ceramic shell 2 is attached to the outer wall of the stove body 1. A quick-connect connector is provided between the ceramic shell 2 and the stove body 1. A first vertical slot 5 and a second vertical slot 6 are provided in the ceramic shell 2. Figure 1 and Figure 14 The induction column 4 is vertically inserted into the No. 1 vertical slot 5, and the top and bottom ends of the induction column 4 are respectively provided with an induction terminal 7 and a No. 1 conductive terminal 8. The bottom of the ceramic shell 2 is provided with a clamping mechanism for fixing the induction column 4. The ignition column 3 is vertically inserted into the No. 2 vertical slot 6, and the top and bottom ends of the ignition column 3 are respectively provided with a discharge terminal 9 and a No. 2 conductive terminal 10.

[0034] A conductive on-off mechanism is provided at the bottom of the ceramic shell 2, which includes a cylindrical shell 11, a conductive seat 12, a No. 1 spring 13, an annular iron 14 and an annular electromagnet 15. The cylindrical shell 11 is vertically fixed to the ceramic shell 2, and the cylindrical shell 11 is sleeved outside the ignition column 3. The conductive seat 12 is fixed to the bottom end of the cylindrical shell 11. The No. 1 spring 13 is vertically arranged between the conductive seat 12 and the ignition column 3. The annular iron 14 is coaxially sleeved on the cylindrical shell 11, and the annular iron 14 is connected to the lower end of the ignition column 3. The annular electromagnet 15 is coaxially fixed on the cylindrical shell 11, and the annular electromagnet 15 is located below the annular iron 14.

[0035] When installing the ignition assembly, first fix the ceramic shell 2 to the outer wall of the stove body 1 through the quick connector, and then insert the ignition column 3 into the second vertical slot 6. During this process, the lower end of the ignition column 3 will drive the annular iron 14 close to the annular electromagnet 15. At the same time, the first spring 13 is compressed by the ignition column 3. When the annular electromagnet 15 is energized, the annular iron 14 will be attracted by the annular electromagnet 15. At this time, the ignition column 3 is fixed, and the second conductive end 10 located at the bottom of the ignition column 3 will be in contact with the The conductive seat 12 fits in place. After the ignition column 3 is installed, the induction column 4 is inserted into the No. 1 vertical slot 5. After the induction column 4 is inserted into the No. 1 vertical slot 5, the induction column 4 is rotated so that the induction terminal 7 at the top of the induction column 4 faces the discharge terminal 9 at the top of the ignition column 3. Thereafter, the induction column 4 is fixed by the clamping mechanism. Among them, the No. 1 conductive terminal 8 at the bottom of the induction column 4 is electrically connected to the control machine (not shown in the figure), and the No. 2 conductive terminal 10 at the bottom of the ignition column 3 is connected to the power supply (not shown in the figure). When the ignition column 3 is electrically connected, liquefied gas is sprayed upward from the stove body 1. When the ignition column 3 is energized, the discharge end 9 at the top of the ignition column 3 will generate an electric spark, thereby igniting the liquefied gas in the stove body 1 to generate a stove fire. When the stove body 1 is ignited, the induction end 7 at the top of the induction column 4 will sense the current around the discharge end 9. When the ignition column 3 is damaged due to improper use or corroded due to long-term use, the discharge end 9 on the ignition column 3 will discharge abnormally after the ignition column 3 is energized, and the ignition column 3 may also leak electricity. At this time, the sensing end of the induction column 4 will detect the abnormality of the discharge end 9 of the ignition column 3. After that, the induction column 4 will cut off the power of the annular electromagnet 15 through the control machine. When the annular electromagnet 15 is de-energized, the No. 1 spring 13 releases the elastic force to push the ignition column 3 up, and finally the No. 2 conductive end 10 on the ignition column 3 will be separated from the conductive seat 12, thereby cutting off the power of the ignition column 3, preventing the ignition column 3 from causing the stove body 1 to explode due to abnormal discharge of the discharge end 9, and preventing the leakage of the ignition column 3 from affecting personal safety.

[0036] In order to show the specific structure of the quick connect connector, the following features are set:

[0037] The ceramic shell 2 is rectangular, and the side of the ceramic shell 2 facing the stove body 1 is formed with an arc-shaped surface 16 that fits with the outer wall of the stove body 1. There are two groups of quick-connect connectors, and the two groups of quick-connect connectors are respectively arranged on both sides of the ceramic shell 2. Each group of quick-connect connectors includes a limit pin 17, a No. 2 spring 18, an insert 19 and a No. 1 oblique wedge block 20. The insert 19 is formed on the outer wall of the stove body 1. Slots 21 are provided on both sides of the ceramic shell 2. Each insert 19 is horizontally inserted into the corresponding slot 21. A vertical slide 22 is provided in the insert 19. The No. 2 spring 18 is vertically provided in the slide 22. The limit pin 17 slides vertically in the slide 22. The two ends of the No. 2 spring 18 respectively conflict with the bottom end of the limit pin 17 and the inner bottom wall of the slide 22. Figure 6 As shown, the first oblique wedge block 20 is formed on the outer wall of the ceramic shell 2 , and the upper end of the limiting pin 17 is formed with a second oblique wedge block 23 that is wedge-matched with the first oblique wedge block 20 .

[0038] In the initial state, the second spring 18 releases its elastic force, thereby pushing the limit pin 17 upward, and finally the second oblique wedge block 23 provided at the upper end of the limit pin 17 will extend out of the plug block 19. When installing the ceramic shell 2, the curved surface 16 on the ceramic shell 2 is facing the stove body 1 and the ceramic shell 2 is pushed toward the stove body 1. During this process, the plug block 19 provided on the outer wall of the stove body 1 will be inserted into the slot 21 on one side of the ceramic shell 2. At the same time, the No. 1 oblique wedge block 20 provided on the ceramic shell 2 will conflict with the No. 2 oblique wedge block 23 on the limit pin 17. Thereafter, the No. 2 oblique wedge block 23 will be pressed due to a The second bevel block 18 will be pressed down by the second spring 18, and the first bevel block 20 will be pressed down by the second spring 18. The second bevel block 18 will be pressed down by the second spring 18, and the second bevel block 18 will be pressed down by the second spring 18. The second bevel block 18 will be pressed down by the second spring 18, and the first bevel block 20 will be pressed down by the second spring 18. The first bevel block 20 will be pressed down by the second spring 18, and the first bevel block 20 will be pressed down by the second spring 18, and the first bevel block 20 will be pressed down by the second spring 18, and the outward displacement of the ceramic shell 2 will be restricted.

[0039] In order to show how to disassemble the ceramic housing 2, the following features are set:

[0040] A strip groove 24 connected to the slide groove 22 is formed on one side of each insert block 19, and each strip groove 24 is vertical. A push block 25 extending from the strip groove 24 is formed on the outer wall of each limit pin 17. A stop block 26 is provided on the side of each No. 1 oblique wedge block 20 to limit the upward movement of the limit pin 17, and each stop block 26 is fixedly connected to the side wall of the ceramic shell 2.

[0041] When the curved surface 16 on the ceramic shell 2 fits with the outer wall of the stove body 1, the No. 2 inclined wedge block 23 will pass over the No. 1 inclined wedge block 20. At this time, the limit pin 17 will be pushed up due to the elastic force of the No. 2 spring 18. Finally, the No. 1 inclined wedge block 20 will upwardly conflict with the stop block 26, and the stop block 26 will limit the rising stroke of the limit pin 17. When the ceramic shell 2 needs to be disassembled, the two limit pins 17 are pushed downward respectively by the two push blocks 25. When the limit pins 17 are retracted into the slide groove 22, the ceramic shell 2 can be pulled out horizontally.

[0042] In order to show the specific structure of the sensing column 4, the following features are set:

[0043] The sensing column 4 includes a No. 1 ceramic column 27 and a No. 1 conductive rod 28. The upper end of the No. 1 ceramic column 27 is bulged, and the middle part of the No. 1 ceramic column 27 is polygonal. A sleeve 29 is rotatably provided in the No. 1 vertical slot 5. The sleeve 29 is provided with a polygonal groove that is embedded in the middle part of the No. 1 ceramic column 27. The No. 1 conductive rod 28 is vertically fixed in the No. 1 ceramic column 27, and the No. 1 conductive rod 28 is coaxial with the No. 1 ceramic column 27. The upper end of the No. 1 conductive rod 28 is the sensing terminal 7, and the lower end of the No. 1 conductive rod 28 is the No. 1 conductive terminal 8.

[0044] When installing the sensing column 4, the sensing column 4 is inserted downward into the sleeve 29 in the No. 1 vertical groove 5. Since the polygonal groove in the sleeve 29 is embedded with the polygonal middle part of the No. 1 ceramic column 27, the rotation of the sensing column 4 can be achieved through the sleeve 29. When the No. 1 ceramic column 27 is inserted downward into the sleeve 29, the enlarged upper end of the No. 1 ceramic column 27 will downwardly conflict with the top of the ceramic shell 2. At this time, the descent of the No. 1 ceramic column 27 is restricted by the enlarged upper end of the No. 1 ceramic column 27, and the lower end of the No. 1 ceramic column 27 is fixed by the clamping mechanism.

[0045] In order to show the specific structure of the clamping mechanism, the following features are set:

[0046] The clamping mechanism includes a fixed clamping block 30, a movable clamping block 31 and a resistance piece. The fixed clamping block 30 is fixed in an arc shape at the bottom of the ceramic shell 2, and the movable clamping block 31 is arranged in an arc shape on the opposite side of the fixed clamping block 30. The resistance piece includes a limit seat 32, a slide rod 33, a bolt 34 and an internal threaded sleeve 35. The limit seat 32 is fixed in a strip shape at the bottom of the ceramic shell 2, and the middle part of the slide rod 33 is slidably connected to the limit seat 32. The movable clamping block 31 is fixed at one end of the slide rod 33, and the other end of the slide rod 33 is formed with a resistance piece 36. The internal threaded sleeve 35 is fixed on the outer wall of the ceramic shell 2, and the bolt 34 rotates in the internal threaded sleeve 35. One end of the bolt 34 resists the resistance piece 36.

[0047] By rotating the bolt 34 to abut the block 36, the slide bar 33 is driven to move horizontally, and the slide bar 33 drives the movable clamping block 31 to move toward the fixed clamping block 30. Finally, the lower end of the sensing column 4 is clamped between the fixed clamping block 30 and the movable clamping block 31. When the sensing column 4 needs to be disassembled, the bolt 34 is rotated in the opposite direction so that the bolt 34 no longer abuts the block 36. The movable clamping block 31 is loosened, and the sensing column 4 can be finally pulled out of the sleeve 29.

[0048] In order to show the specific structure of the ignition column 3, the following features are set:

[0049] The ignition column 3 includes a No. 2 ceramic column 37 and a No. 2 conductive rod 38. The upper end of the No. 2 ceramic column 37 is bulged, the middle part of the No. 2 ceramic column 37 is polygonal, the No. 2 vertical groove 6 is a polygonal groove, and the polygonal middle part of the No. 2 ceramic column 37 is embedded in the No. 2 vertical groove 6. The No. 2 conductive rod 38 is vertically fixed in the No. 2 ceramic column 37, and the No. 2 conductive rod 38 is coaxial with the No. 2 ceramic column 37. The upper end of the No. 2 conductive rod 38 is the discharge end 9, and the lower end of the No. 2 conductive rod 38 is the No. 2 conductive end 10.

[0050] When installing the ignition column 3, insert the ignition column 3 directly downward into the second vertical groove 6. Since the second vertical groove 6 is embedded in the multi-faceted middle part of the second ceramic column 37, the ignition column 3 cannot rotate after being inserted into the second vertical groove 6, thereby ensuring that the discharge end 9 on the ignition column 3 can face the stove body 1.

[0051] In order to show how the ignition column 3 is connected to the ring iron 14, the following features are set:

[0052] The upper end of the cylindrical shell 11 is an open structure, and the lower end of the cylindrical shell 11 is a closed structure. A sliding sleeve 39 is provided in the cylindrical shell 11. The upper end of the sliding sleeve 39 is an open structure. The lower end of the sliding sleeve 39 is coaxially formed with a No. 1 retaining ring 40. The lower end of the No. 2 ceramic column 37 is downwardly inserted into the sliding sleeve 39, and the No. 2 conductive end 10 passes downwardly from the No. 1 retaining ring 40. The upper end of the sliding sleeve 39 is coaxially formed with a convex ring 41, and the outer wall of the convex ring 41 fits with the inner wall of the cylindrical shell 11. A No. 2 retaining ring 42 is coaxially formed in the lower end of the cylindrical shell 11. The No. 1 spring 13 is coaxially sleeved outside the sliding sleeve 39, and the two ends of the No. 1 spring 13 respectively conflict with the convex ring 41 and the No. 2 retaining ring 42, and the annular iron 14 is connected to the sliding sleeve 39.

[0053] The cylindrical shell 11 and the sleeve 39 are both made of ceramic. When the ignition column 3 is inserted downward into the No. 2 vertical slot 6, the lower end of the No. 2 ceramic column 37 will be inserted downward into the sleeve 39, and the No. 2 conductive end 10 will pass through the No. 1 baffle ring 40. In the process of the ignition column 3 continuously descending, the sleeve 39 will be resisted by the No. 2 ceramic column 37 to compress the No. 1 spring 13 downward. At the same time, the annular iron 14 connected to the sleeve 39 will contact the annular electromagnet 15 downward, and the annular iron 14 will be adsorbed by the annular electromagnet 15. At this time, the sleeve 39 is in a fixed state, and the No. 2 conductive end 10 will resist the conductive seat 12. Therefore, when the conductive seat 12 is energized, the current will flow along the conductive seat 12 to the No. 2 conductive end 10.

[0054] In order to show how the ring iron 14 is connected to the sliding sleeve 39, the following features are provided:

[0055] A No. 1 annular shell 43 is coaxially provided on the outer wall of the cylindrical shell 11, and the annular iron 14 is fixed in the No. 1 annular shell 43. The No. 1 annular shell 43 is provided with a number of L-shaped connecting rods 44 evenly distributed along the circumferential direction of the No. 1 annular shell 43. A number of avoidance grooves 45 corresponding to the L-shaped connecting rods 44 are opened on the outer wall of the cylindrical shell 11. The vertical end of each L-shaped connecting rod 44 is downwardly fixedly connected to the No. 1 annular shell 43, and the horizontal end of each L-shaped connecting rod 44 passes through the corresponding avoidance groove 45 and is fixedly connected to the convex ring 41. A No. 2 annular shell 46 is provided below the No. 1 annular shell 43, and the No. 2 annular shell 46 is fixedly connected to the outer wall of the cylindrical shell 11. The annular electromagnet 15 is fixed in the No. 2 annular shell 46.

[0056] When the sleeve 39 is driven to descend by the No. 2 ceramic column 37, the sleeve 39 will drive the No. 1 annular shell 43 to descend through several L-shaped connecting rods 44, so that the annular iron 14 provided in the No. 1 annular shell 43 will approach the annular electromagnet 15 provided in the No. 2 annular shell 46. When the annular iron 14 fits with the annular electromagnet 15, the annular iron 14 is adsorbed by the annular electromagnet 15, and finally the sleeve 39 will be in a fixed state, and then the No. 2 ceramic column 37 inserted in the sleeve 39 will be in a fixed state. Among them, a circle of rubber ring (not shown in the figure) can be attached to the inner wall of the sleeve 39 to increase the friction between the sleeve 39 and the No. 2 ceramic column 37 through the rubber ring, so that the lower end of the No. 2 ceramic column 37 can be tightly inserted into the sleeve 39.

[0057] Working principle: When installing the ignition assembly, first fix the ceramic shell 2 to the outer wall of the stove body 1 through the quick connector, and then insert the ignition column 3 into the second vertical slot 6. During this process, the lower end of the ignition column 3 will drive the annular iron 14 close to the annular electromagnet 15. At the same time, the first spring 13 is compressed by the ignition column 3. When the annular electromagnet 15 is energized, the annular iron 14 will be attracted by the annular electromagnet 15. At this time, the ignition column 3 is fixed, and the second conductive terminal 1 located at the bottom of the ignition column 3 0 will fit with the conductive seat 12. When the ignition column 3 is installed, the induction column 4 is inserted into the No. 1 vertical slot 5. After the induction column 4 is inserted into the No. 1 vertical slot 5, the induction column 4 is rotated so that the induction terminal 7 at the top of the induction column 4 faces the discharge terminal 9 at the top of the ignition column 3. Thereafter, the induction column 4 is fixed by the clamping mechanism. Among them, the No. 1 conductive terminal 8 at the bottom of the induction column 4 is electrically connected to the control machine (not shown in the figure), and the No. 2 conductive terminal 10 at the bottom of the ignition column 3 is electrically connected to the power supply (not shown in the figure). When the ignition column 3 is electrically connected, the liquefied gas is ejected upward from the stove body 1. When the ignition column 3 is energized, the discharge end 9 at the top of the ignition column 3 will generate an electric spark, thereby igniting the liquefied gas in the stove body 1 to generate a stove fire. When the stove body 1 is ignited, the induction end 7 at the top of the induction column 4 will sense the current around the discharge end 9. When the ignition column 3 is damaged due to improper use or corroded due to long-term use, the discharge end 9 on the ignition column 3 will discharge abnormally after the ignition column 3 is energized, and the ignition column 3 may also leak. At this time, the sensing end of the induction column 4 will detect the abnormality of the discharge end 9 of the ignition column 3. Thereafter, the induction column 4 will cut off the power to the annular electromagnet 15 through the control machine. When the annular electromagnet 15 is powered off, the No. 1 spring 13 releases its elastic force to push the ignition column 3 up, and finally the No. 2 conductive end 10 on the ignition column 3 will be separated from the conductive seat 12, thereby cutting off the power to the ignition column 3, preventing the ignition column 3 from causing the stove body 1 to explode due to abnormal discharge of the discharge end 9, and preventing the leakage of the ignition column 3 from affecting personal safety.
