Description

Technical Field

[0001] This invention relates to the field of liquefied gas burner technology, specifically to an energy-saving burner. Background Technology

[0002] A high-efficiency and energy-saving burner, disclosed in the prior art with the publication number "CN205939133U", includes a burner assembly and an inner flame cap, an outer flame cap, and a flame distribution seat disposed on the burner assembly. The burner assembly consists of an upper burner, a lower burner, and an injector tube assembled together. The upper burner has an upper combustion chamber connecting the inner flame cap and / or the outer flame cap, and the injector tube has an injector channel for supplying air. The lower burner has a lower combustion chamber connecting the upper combustion chamber and the injector channel. A regulating pipe is slidably disposed within the injector channel, and the air-to-gas ratio is adjusted by sliding the regulating pipe. The burner assembly of this structure is made of aluminum alloy, resulting in low manufacturing costs. The regulating pipe within the injector tube can adjust the air intake by sliding, thereby adjusting the air-to-gas ratio. A guide surface is provided in the lower combustion chamber corresponding to the air outlet of the injector channel to prevent air from colliding during transportation, which would reduce its transportation pressure.

[0003] However, the device still has some obvious drawbacks in use: although the device can adjust the air intake by sliding, it still requires manual ignition. The adjustment process needs to be done manually, and the existing burner ignition mechanism is relatively simple. It usually generates an electric spark through the battery box, but when the battery is depleted, it needs to be replaced, which will affect the normal operation of the burner. Summary of the Invention

[0004] The purpose of this invention is to provide an energy-saving burner to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An energy-saving burner, comprising:

[0007] The outer flame cover of the burner has an assembly hole at the center of its bottom for installing the inner flame cover of the burner.

[0008] The burner inner flame cover is fixedly installed in the assembly hole. The burner inner flame cover includes a combustion zone, an ignition zone and a gas supply pipe. The combustion zone is located above the ignition zone and the two are connected through a combustion nozzle. One end of the gas supply pipe is inserted into the ignition zone and the other end is connected to the gas source through a pipe. A first regulating valve and a second regulating valve are provided in the gas supply pipe.

[0009] An induction ignition device includes an induction slide rod, which is vertically mounted within an induction through-hole in the burner's outer flame cap. The upper end of the slide rod protrudes from the burner's outer flame cap without external force and slides downwards under the weight of an object placed on the burner's outer flame cap. During this downward movement, the slide rod adjusts the opening of a second regulating valve via a flame adjustment mechanism. The slide rod is also movably connected to a contact fuel switch. When the slide rod reaches its bottom limit position, the contact fuel switch is activated, releasing an electric spark to the ignition zone for ignition.

[0010] A backup mechanical ignition device includes a firing column. A piezoelectric ceramic body is fixedly installed at the bottom of the firing column. A pair of second spark columns are connected to the piezoelectric ceramic body. The ends of the second spark columns away from the piezoelectric ceramic body extend into the ignition zone. The piezoelectric ceramic body is also connected to an impact block via a traction spring. The end of the impact block away from the piezoelectric ceramic body is connected to a shape memory helical spring. The end of the shape memory helical spring away from the impact block extends upward into a heating hole in the burner's outer flame cap and is fixedly connected to a heating block installed in the heating hole. The impact block is pulled upward and limited during the heating process of the shape memory helical spring, and is released during contact with an unlocking mechanism provided in the induction slide rod. Thus, the impact block strikes the piezoelectric ceramic body, ultimately generating an electric spark on the second spark column located on one side of the ignition zone.

[0011] Preferably, a contact piece is fixedly connected to the bottom of the sensing slide rod. The contact piece is in movable cooperation with the spaced contact spring of the contact fuel switch. A pair of first electric spark columns connected to the contact fuel switch extend upward into the ignition zone. When the contact piece contacts the spaced contact spring of the contact fuel switch, an electric spark is generated on the first electric spark column, thereby igniting the liquefied gas in the ignition zone.

[0012] Preferably, a limiting block is telescopically installed on one side of the impact block. The limiting block is movably engaged with the limiting hole on the side of the firing column. During the combustion process of the inner burner cap, heat is conducted to the shape memory helical spring through the outer burner cap. The shape memory helical spring contracts during the heating process, thereby overcoming the elastic force of the traction spring and pulling the impact block upward until the limiting block on the side of the impact block engages with the limiting hole of the firing column. At this time, the limiting block is in the energy storage limiting state.

[0013] Preferably, the unlocking mechanism inside the sensing slide is a release limit lever. The sensing slide has a through hole, and the release limit lever, which is fixed and rotates around a fixed axis, is movably inserted into the through hole. The release limit lever contacts the limit block during the descent of the sensing slide, thereby releasing the limit of the impact block. The impact block accelerates and impacts the piezoelectric ceramic body under the traction of the traction spring, thereby generating an electric spark at one end of the second electric spark column located in the ignition zone, and then igniting the liquefied gas in the ignition zone.

[0014] Preferably, a positioning plate is fixedly installed at the bottom of the burner outer flame cover by bolts. The positioning plate has a through hole for inserting the sensing slide rod. A pair of positioning rods are also fixedly installed on the positioning plate. A support platform is fixedly installed at the bottom of the positioning rod. A pull plate is also fixedly installed on the sensing slide rod between the positioning plate and the support platform. A compression spring is sleeved on the sensing slide rod between the pull plate and the support platform. The compression spring pushes the sensing slide rod to protrude from the burner outer flame cover without external force.

[0015] Preferably, both the first and second regulating valves include a fixed valve plate and a movable valve plate. The movable valve plate of the first regulating valve is coaxially and fixedly connected to the main switch knob. The opening and closing angle of the first regulating valve is adjusted by rotating the main switch knob. The movable valve plate of the second regulating valve is coaxially and fixedly connected to the winding reel. A torsion spring is also installed on the rotating shaft of the winding reel. The torsion spring drives the winding reel to rotate without external force. An opening adjustment rope is wound on the winding reel. The other end of the opening adjustment rope is connected to the pull plate. The sensing slide pushes the winding reel to rotate during descent, thereby gradually increasing the opening of the second regulating valve and thus increasing the air intake.

[0016] Preferably, the release limit lever can rotate 90° around a fixed axis within the through hole of the sensing slide rod, thus allowing it to operate in both normal and ignition modes at its two extreme rotational positions. In normal mode, the release limit lever disengages from the limit block, and the descent of the sensing slide rod will not push the limit block out of lock. In ignition mode, the release limit lever engages with the limit block, and the descent of the sensing slide rod pushes the limit block out of lock, thereby enabling ignition operation.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention can not only automatically reduce the flame intensity of the stove body after an object leaves the outer burner cap, but also automatically ignite the stove body by the weight of the object itself. Furthermore, its two built-in ignition devices can complement each other to meet the ignition requirements in different scenarios, ensure the normal operation of the burner, reduce the difficulty of operating the burner, and effectively save liquefied petroleum gas fuel, making it energy-saving and environmentally friendly.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-6 The present invention provides a technical solution:

[0028] Example 1:

[0029] An energy-saving burner, comprising:

[0030] The outer flame cover 1 of the burner is used to place the object to be heated. The bottom center of the outer flame cover 1 of the burner has an assembly hole for the installation of the inner flame cover 2 of the burner.

[0031] The burner inner flame cover 2 is fixedly installed in the assembly hole. The burner inner flame cover 2 includes a combustion zone 3, an ignition zone 4 and a gas supply pipe 5. The combustion zone 3 is located above the ignition zone 4 and the two are connected through a combustion nozzle 6. One end of the gas supply pipe 5 is inserted into the ignition zone 4 and the other end is connected to the gas source through a pipe. A first regulating valve and a second regulating valve are installed in the gas supply pipe 5.

[0032] The induction ignition device includes an induction slide rod 7, which is vertically mounted within an induction through-hole in the burner outer flame cap 1. The upper end of the induction slide rod 7 protrudes from the burner outer flame cap 1 without external force and slides downwards under the weight of an object placed on the burner outer flame cap 1. During this downward movement, the induction slide rod 7 adjusts the opening of the second regulating valve via a flame adjustment mechanism. The induction slide rod 7 is also movably connected to a contact fuel switch 8. When the induction slide rod 7 reaches its bottom limit position, the contact fuel switch 8 is activated, releasing an electric spark to the ignition zone 4 for ignition.

[0033] A backup mechanical ignition device includes a firing pin 9. A piezoelectric ceramic body 10 is fixedly installed at the bottom of the firing pin 9. A pair of second electric spark columns 11 are connected to the piezoelectric ceramic body 10. The end of the second electric spark column 11 away from the piezoelectric ceramic body 10 extends into the ignition zone 4. The piezoelectric ceramic body 10 is also connected to an impact block 13 via a traction spring 12. The end of the impact block 13 away from the piezoelectric ceramic body 10 is connected to a shape memory helical spring 14. The end of the shape memory helical spring 14 away from the impact block 13 extends upward into a heating hole opened in the burner outer flame cap 1 and is fixedly connected to a heating block 15 installed in the heating hole. The impact block 13 is pulled upward and limited during the heating process of the shape memory helical spring 14, and is released during the contact with the unlocking mechanism set in the induction slide 7. Thus, the impact block 13 strikes the piezoelectric ceramic body 10, and finally generates an electric spark on the second electric spark column 11 located on one side of the ignition zone 4.

[0034] In this embodiment, an inner burner cap 2 is installed at the bottom of the outer burner cap 1. The bottom of the outer burner cap 1 has a funnel shape with a gradually narrowing inner diameter, which can better concentrate heat. The inner burner cap 2 adopts a form commonly used in the prior art, including a combustion zone 3, an ignition zone 4, and a gas supply pipe 5. Unlike the prior art, a first regulating valve and a second regulating valve are provided in the gas supply pipe 5. The two are located in the same gas supply pipe 5, with the first regulating valve at the front end in the gas intake direction and the second regulating valve at the rear end in the gas intake direction. Both the first and second regulating valves include a fixed valve plate 27 and a movable valve plate 28. The movable valve plate 28 of the first regulating valve is coaxially and fixedly connected to the main switch knob 29. Refer to the appendix of the instruction manual. Figure 6The opening of the movable valve plate 28 connected to the main switch knob 29 is adjusted by rotating the main switch knob 29, thereby regulating the amount of gas entering the gas supply pipe 5. The movable valve plate 28 can be completely closed, thus blocking the liquefied gas from entering the burner inner cap 2 through the gas supply pipe 5. Therefore, the main switch knob 29 serves as the main switch for controlling the amount of gas entering and closing. The second regulating valve adjusts its opening during the raising and lowering of the sensing slide rod 7. Through the design of the mechanical structure, the movable valve plate 28 in the second regulating valve is at its minimum opening when the sensing slide rod 7 is at its upper limit position. By setting it so that liquefied gas can still pass through when the second regulating valve is at its minimum opening, the flame in the ignition zone 4 can still be maintained when the sensing slide rod 7 rises to its limit position. Furthermore, when the object to be heated is placed, its own weight pushes the sensing slide bar 7 down, which in turn drives the moving valve plate 28 inside the second regulating valve to rotate. When the sensing slide bar 7 slides to the lowest position, the opening of the second regulating valve is at its maximum, thereby achieving the operation of automatically reducing the flame after the pot is removed from the heat. It should be noted that when igniting, the opening of the first regulating valve is adjusted to the minimum. This way, even if the opening of the second regulating valve is at its maximum, the gas flow entering the ignition zone 4 is still constrained by the minimum opening of the first regulating valve, thus ensuring that no deflagration occurs during the ignition process. After ignition, the first regulating valve is adjusted to the required opening to increase the gas output. Subsequent gas output adjustment is performed through the second regulating valve.

[0035] Furthermore, when the sensing slide 7 descends to its bottom limit position, it is also movably connected to the contact fuel switch 8, thereby releasing an electric spark to the ignition zone 4 through the contact fuel switch 8 for ignition. This ignition method is achieved by a battery installed in the contact fuel switch 8. The contact fuel switch 8 is configured to perform a preset number of pulse ignitions each time it contacts the bottom of the sensing slide 7, and then stop after reaching the preset number of ignitions. Additionally, this embodiment also includes a backup mechanical ignition device, which uses a purely mechanical structure for ignition. This ignition method is similar to that of a common lighter. The heat generated during the heating process of the stove body 1 drives the shape memory coil spring 14 to contract. Since the shape memory coil spring 14 is relatively soft at room temperature, its tension cannot compete with the elasticity of the traction spring 12. Therefore, at room temperature, the elasticity of the traction spring 12 does positive work, while in the combustion state of the stove body 1, the contraction force of the shape memory coil spring 14 does positive work. The shape memory helical spring 14 pulls the impact block 13 upward when the stove body 1 is burning, and puts the impact block 13 in a limited state. It is released during the contact process through the unlocking mechanism set in the induction slide rod 7. The impact block 13 accelerates the impact on the piezoelectric ceramic body 10. The piezoelectric ceramic body 10 is a composite piezoelectric ceramic structure. When impacted, current is generated on the piezoelectric ceramic bodies 10 on the upper and lower sides. By connecting the piezoelectric ceramic body 10 to the second electric spark column 11, the spark generated by the second electric spark column 11 is used to ignite the liquefied gas. This ignition method is a supplement to the above-mentioned contact fuel switch 8, so as to ensure that the stove body 1 can still perform ignition operation when the battery is not working. In order to ensure that the induction slide rod 7 can still work normally under the high temperature of the stove body combustion, high temperature resistant materials need to be used in the induction slide rod 7. Since slag is generated during the combustion process, it may affect the raising and lowering of the induction slide rod 7. Therefore, it is necessary to regularly spray it with lubricating and anti-rust spray to ensure its lubrication during the raising and lowering process.

[0036] Example 2:

[0037] A contact piece 16 is fixedly connected to the bottom of the sensing slide rod 7. The contact piece 16 is in movable cooperation with the spaced contact spring 17 of the contact fuel switch 8. A pair of first electric spark columns 18 connected to the contact fuel switch 8 extend upward into the ignition zone 4. When the contact piece 16 contacts the spaced contact spring 17 of the contact fuel switch 8, an electric spark is generated on the first electric spark column 18, thereby igniting the liquefied gas in the ignition zone 4.

[0038] In this embodiment, a contact piece 16 is further disclosed at the bottom of the sensing slide bar 7. When the contact piece 16 reaches the lowest side, it cooperates with the spaced contact spring 17 on the contact fuel switch 8 to conduct the circuit of the contact fuel switch 8, and then sends an ignition signal through the circuit board in the contact fuel switch 8, thereby generating an electric spark through the first electric spark column 18 to ignite the liquefied gas in the ignition zone 4.

[0039] Example 3:

[0040] A limiting block 19 is telescopically installed on one side of the impact block 13. The limiting block 19 is in movable cooperation with the limiting hole 20 opened on the side of the firing column 9. During the combustion process of the inner burner cap 2, the heat is conducted to the shape memory coil spring 14 through the outer burner cap 1. The shape memory coil spring 14 contracts during the heating process, thereby overcoming the elastic force of the traction spring 12 and pulling the impact block 13 upward until the limiting block 19 set on the side of the impact block 13 cooperates with the limiting hole 20 of the firing column 9. At this time, the limiting block 19 is in the energy storage limiting state.

[0041] The unlocking mechanism inside the sensing slide rod 7 is a release limit lever 21. The sensing slide rod 7 has a through hole, and the release limit lever 21, which is fixed and rotates around a fixed axis, is movably inserted into the through hole. During the descent of the sensing slide rod 7, the release limit lever 21 contacts the limit block 19, thereby releasing the limit of the impact block 13. The impact block 13 accelerates and impacts the piezoelectric ceramic body 10 under the traction of the traction spring 12, thereby generating an electric spark at one end of the second electric spark column 11 located in the ignition zone 4, and then igniting the liquefied gas in the ignition zone 4.

[0042] The release limit lever 21 can rotate 90° around a fixed axis within the through hole of the sensing slide 7, thus placing it in two extreme rotational positions: normal and ignition modes. In normal mode, the release limit lever 21 disengages from the limit block 19, and the descent of the sensing slide 7 will not push the limit block 19 out of lock. In ignition mode, the release limit lever 21 engages with the limit block 19, and the descent of the sensing slide 7 pushes the limit block 19 out of lock, thereby performing the ignition operation.

[0043] In this embodiment, a limiting mechanism for the impact block 13 is further disclosed. A limiting block 19 is telescopically installed on one side. During the process of the impact block 13 being pulled upward, the limiting block 19 enters the limiting hole 20 to complete the limiting. At this time, the traction spring 12 is in a stretched state, thereby completing the energy storage. When energy release is required, the release limiting lever 21 is moved to put it into the ignition mode. In this mode, the sensing slide 7 descends, causing the release limiting lever 21 to contact the limiting block 19, thereby pushing the limiting block 19 away from the limiting hole 20. At this time, since the stove body is in a closed state... In the current state, the shape memory helical spring 14 is cooled and in a soft state. Therefore, under the pulling action of the traction spring 12, the impact block 13 accelerates to impact the piezoelectric ceramic body 10, thereby generating an electric spark at one end of the second electric spark column 11 located in the ignition zone 4. When the contact fuel switch 8 is working normally, the release limit lever 21 is in the normal mode, so that the traction spring 12 is in the energy storage state for a long time. The release limit lever 21 can only be moved to put it into the ignition mode when the contact fuel switch 8 cannot ignite normally, thus serving as a backup solution other than the contact fuel switch 8.

[0044] Example 4:

[0045] A positioning plate 22 is fixedly installed at the bottom of the burner outer flame cover 1 by bolts. The positioning plate 22 has a through hole for the insertion of the sensing slide rod 7. A pair of positioning rods 23 are also fixedly installed on the positioning plate 22. A support platform 24 is fixedly installed at the bottom of the positioning rod 23. A tension plate 25 is also fixedly installed on the sensing slide rod 7 between the positioning plate 22 and the support platform 24. A compression spring 26 is sleeved on the sensing slide rod 7 between the tension plate 25 and the support platform 24. The compression spring 26 pushes the sensing slide rod 7 to protrude out of the burner outer flame cover 1 without external force.

[0046] In this embodiment, the mounting structure of the sensing slide rod 7 is further disclosed. It is mounted on the bottom of the burner outer flame cover 1 by means of the positioning piece 22. For the specific mounting method, please refer to the appendix of the instruction manual. Figure 1 and 4 The compression spring 26 is used to make the sensing slide rod 7 protrude upward from the burner outer flame cover 1 without external force.

[0047] Example 5:

[0048] Both the first and second regulating valves include a fixed valve plate 27 and a movable valve plate 28. The movable valve plate 28 of the first regulating valve is coaxially and fixedly connected to the main switch knob 29. The opening and closing angle of the first regulating valve is adjusted by rotating the main switch knob 29. The movable valve plate 28 of the second regulating valve is coaxially and fixedly connected to the winding reel 30. A torsion spring is also installed on the rotating shaft of the winding reel 30. The torsion spring drives the winding reel 30 to rotate without external force. An opening adjustment rope 31 is wound on the winding reel 30. The other end of the opening adjustment rope 31 is connected to the pull plate 25. The sensing slide 7 pushes the winding reel 30 to rotate during descent, thereby gradually increasing the opening of the second regulating valve and thus increasing the air intake.

[0049] In this embodiment, the structure of the first regulating valve and the second regulating valve are further disclosed, as well as the adjustment method of the moving valve plate 28 in the second regulating valve. The moving valve plate 28 in the second regulating valve is coaxially fixedly connected to the winding reel 30, and a torsion spring is provided on the winding reel 30. The torsion spring can cause the winding reel 30 to reset without external force, so that the moving valve plate 28 in the second regulating valve is at its minimum opening. During the descent of the sensing slide rod 7, it drives the pulling plate 25 to descend. The descent of the pulling plate 25 pulls the opening adjustment rope 31 to unwind, thereby pushing the winding reel 30 to rotate, thereby adjusting the opening of the moving valve plate 28. This ensures that when the object to be heated is placed, the second regulating valve is at its maximum opening, and after the object leaves the outer flame cap 1 of the burner, the second regulating valve is at its minimum opening, thereby achieving the purpose of energy saving and emission reduction.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
