[0062] The present invention will be described more clearly and completely below with reference to the accompanying drawings, but this will not limit the scope of the present invention to the embodiments.

[0063] like Figures 1 to 6 As shown, this embodiment provides a pollution prevention and ventilation device 100 for a burner 200. The pollution prevention and ventilation device 100 also includes a peripheral wall 110 and a pollution prevention plate 120. A ventilation opening 113 is provided on the peripheral wall 110, and the opening of the ventilation opening 113 is adjustable. The pollution prevention plate 120 is provided at the bottom of the peripheral wall 110 to block the lower opening of the peripheral wall 110.

[0064] In this embodiment, the peripheral wall 110 and the anti-fouling plate 120 are provided to collect spilled liquids, splashed oil and water, etc., generated by the user during cooking, so as to facilitate the cleaning of the burner 200; the vent 113 on the peripheral wall 110 is conducive to the supply of secondary air when the burner 200 is burning; in addition, the opening of the vent 113 is adjustable, which is conducive to flexibly adjusting the amount of secondary air entering according to the combustion of the burner 200.

[0065] It should be noted that the anti-fouling ventilation device 100 can both prevent fouling and provide secondary air supply. Specifically, the anti-fouling plate 120 is used for fouling prevention, and the ventilation openings 113 on the peripheral wall 110 are used for secondary air supply. In addition, the anti-fouling ventilation device 100 has a certain liquid capacity, meaning that the ventilation openings 113 should not be set too low; otherwise, overflowing liquid and other contaminants on the anti-fouling plate 120 will flow out through the ventilation openings 113, thus contaminating the burner 200. The aforementioned burner 200 includes an outer ring mixing chamber 230. The burner 200 is positioned below the outer ring burner cap 220. The inner peripheral wall of the outer ring mixing chamber 230 has multiple waist-shaped openings 231 (side air inlets) to supplement the secondary air required for combustion. The burner 200 also has a gap region 260 between the outer ring burner cap and the inner ring burner cap. The anti-fouling ventilation device 100 is located in the gap region 260. This means that air passing through the ventilation opening 113 must first pass through the multiple waist-shaped openings 231 of the outer ring mixing chamber 230 before entering through the ventilation opening 113 to supplement the secondary air for the inner ring burner cap. A gap is left between the outer peripheral wall of the outer ring mixing chamber 230 and the cooktop surface. Air from the outer periphery of the burner 200 flows in through this gap and enters the gap region 260 through the side air inlets 260 on the inner peripheral wall of the outer ring mixing chamber 230.

[0066] Reference Figures 1 to 4 It is understood that the peripheral wall 110 includes an inner ring plate 111 and an outer ring plate 112. The inner ring plate 111 has a first ventilation opening 1111 on its ring wall, and the outer ring plate 112 has a second ventilation opening 1121 on its ring wall. The outer ring plate 112 is rotatably fitted on the outside of the inner ring plate 111 to adjust the overlap of the first ventilation opening 1111 and the second ventilation opening 1121. The overlap of the first ventilation opening 1111 and the second ventilation opening 1121 is the opening of the ventilation opening 113. The anti-fouling plate 120 is set at the bottom of the inner ring plate 111 to block the lower opening of the inner ring plate 111.

[0067] In this embodiment, the first vent 1111 and the second vent 1121 are provided for secondary air supply when the burner 200 is burning. The outer ring plate 112 is rotatably sleeved on the outside of the inner ring plate 111 (at this time, the outer ring plate 112 rotates while the inner ring plate 111 remains stationary), which helps to make the structure of the anti-pollution ventilation device 100 compact and reduce its space occupation. In addition, it can also make the outer ring plate 112 and the inner ring plate 111 fit as close as possible, so that the first vent 1111 and the second vent 1121 fit as close as possible, thereby improving the efficiency of secondary air supply. Moreover, the above-mentioned arrangement allows for simple and reliable operation to adjust the amount of secondary air supply.

[0068] It should be noted that when the burner 200 experiences flame detachment, the outer ring plate 112 can be adjusted to reduce the opening, thereby reducing the amount of secondary air supplied to the burner 200 from the atmosphere and effectively solving the flame detachment problem. When the burner 200 produces a yellow flame, the outer ring plate 112 can be adjusted to increase the opening, thereby increasing the amount of secondary air supplied to the burner 200 from the atmosphere and effectively solving the yellow flame problem. In the design of the burner 200, the optimal opening for secondary air supply is generally designed with an overlap of half that is completely overlapping the first vent 1111 and the second vent 1121.

[0069] Reference Figure 2 and 5 It is understood that the central area of ​​the anti-fouling plate 120 is provided with a mounting hole 121, which allows the inner ring flame cap 210 of the burner 200 to pass through.

[0070] In this embodiment, the mounting hole 121 facilitates the installation of the anti-fouling plate 120 onto the burner 200.

[0071] It should be noted that the mounting hole 121 is fitted onto the outside of the inner ring burner cap 210, and the outer ring burner cap 220 is fitted onto the outside of the anti-pollution ventilation device 100, so that the burner 200 is more compact. In addition, it should be noted that at least two handles 122 are provided on the edge of the mounting hole 121 for taking out the anti-pollution ventilation device 100 for cleaning. The handles 122 extend upwards, and the highest point of the handles 122 is lower than the lowest point of the flame outlet of the inner ring burner cap 210 to prevent the flame from burning the handles 122, resulting in incomplete combustion and excessive smoke. The height of the handles 122 should not be too low, otherwise it will be difficult to grip. The upper part of the handles 122 has a certain angle (20-30 degrees) to facilitate gripping (if the angle is too large, it will be difficult to grip with two fingers; if the angle is too small, it will be easy to slip when gripping with two fingers).

[0072] Reference Figures 1 to 4 It is understood that an actuator is provided on the ring wall of the outer ring plate 112, which is used to drive the outer ring plate 112 to rotate; the actuator is a pull rod 1122, which is provided on the inner peripheral wall 110 at the edge of the second vent 1121 of the outer ring plate 112, and extends through the first vent 1111, and the pull rod 1122 can rotate in the first vent 1111.

[0073] In this embodiment, the actuator is designed to facilitate the rotation of the outer ring plate 112; the pull rod 1122 is disposed on the inner peripheral wall 110 at the edge of the second vent 1121 of the outer ring plate 112, which helps to reduce its space occupation. In addition, the pull rod 1122 disposed on the inner peripheral wall 110 at the edge of the second vent 1121 can maximize and minimize the overlap between the first through hole and the second through hole, that is, the overlap can be maximized; the pull rod 1122 extends through the first vent 1111, which facilitates the operation of the pull rod 1122.

[0074] It should be noted that the aforementioned actuator is not necessarily the manually operated lever 1122, but can also be an electrically controlled remote control device, etc.

[0075] Reference Figure 1 It is understood that the first vent 1111 has two limiting notches along the rotation direction of the outer ring plate 112. The two limiting notches are located at the two circumferential ends of the first vent 1111 and are adapted to the pull rod 1122.

[0076] In this embodiment, the limiting notch facilitates the placement and fixing of the pull rod 1122, preventing the pull rod 1122 from moving arbitrarily and affecting the opening size of the first ventilation opening 1111 and the second ventilation opening 1121.

[0077] It should be noted that even without the aforementioned limiting notch, the two ends of the first ventilation opening 1111 can still limit the pull rod 1122, but this cannot guarantee the stability of the pull rod 1122.

[0078] Reference Figure 1 It is understood that the two limiting notches are the first limiting notch 11111 and the second limiting notch 11112; wherein, when the first limiting notch 11111 is adapted to the pull rod 1122, the overlap is 100%, and when the second limiting notch 11112 is adapted to the pull rod 1122, the overlap is 0%.

[0079] In this embodiment, the provision of the first limiting notch 11111 and the second limiting notch 11112 improves the efficiency of operating the lever 1122 to obtain the desired opening degree.

[0080] It should be noted that when the lever 1122 moves to the middle position of the first vent 1111, the opening is half of the fully open position, which also provides the burner 200 with the optimal amount of secondary air supply for combustion.

[0081] Reference Figures 1 to 4 It is understood that the inner ring plate 111 has a first limiting flange 1112 that is radially outward along its top edge, and the inner ring plate 111 has a second limiting flange 1113 that is radially outward along its bottom edge, and the outer ring plate 112 is located between the first limiting flange 1112 and the second limiting flange 1113.

[0082] In this embodiment, the first limiting flange 1112 and the second limiting flange 1113 are provided to prevent the outer ring plate 112 from moving in the axial direction, thereby affecting the opening.

[0083] It should be noted that the setting of the first limiting flange 1112 and the second limiting flange 1113 does not affect the radial rotation of the outer ring plate 112.

[0084] Reference Figures 1 to 4 It is understood that there are multiple first ventilation openings 1111, which are evenly spaced on the circumferential wall 110 of the inner ring plate 111, and multiple second ventilation openings 1121, which are evenly spaced on the circumferential wall 110 of the outer ring plate 112.

[0085] In this embodiment, the arrangement of multiple first vents 1111 and multiple second vents 1121 and their arrangement method are conducive to improving the efficiency and sufficiency of secondary air supply. Both the first vents and the second vents are arranged corresponding to the waist-shaped port 231 (side air inlet) of the burner to introduce secondary air from the periphery of the burner into the interval area 260 and supply it to the inner ring burner cap.

[0086] It should be noted that the purpose of the multiple solid parts on the vertical side of the inner ring plate 111 (that is, the parts of the inner ring plate 111 that are not the first vent 1111) facing the multiple waist-shaped openings 231 of the outer ring mixing chamber 230 is to cover up the appearance, so that the user cannot see the multiple waist-shaped openings 231 and the overflow liquid will not splash out directly; however, since the diameter of the inner ring plate 111 is smaller than the inner diameter of the outer ring mixing chamber 230, there is an air passage, so the air passing through the waist-shaped openings 231 can enter the vent.

[0087] like Figure 5 and 6 As shown, this embodiment also provides a burner 200, which further includes the aforementioned anti-pollution ventilation device 100, which is disposed between the inner ring flame cap 210 and the outer ring flame cap 220 of the burner 200.

[0088] In this embodiment, the anti-pollution ventilation device 100 is designed to maximize the capacity to contain spilled or splashed oil and water from cooking food generated during the operation of the burner 200.

[0089] It should be noted that the inner ring flame cap 210 is provided with a thermocouple 240 and an ignition needle 250. The mounting hole 121 has a thermocouple hole 123 and an ignition needle hole 124 along its edge. The thermocouple hole 123 and the ignition needle hole 124 are used to fit the thermocouple 240 and the ignition needle 250 to achieve positioning of the anti-pollution ventilation device 100.

[0090] This embodiment also provides a stove, which includes the burner 200 described above.

[0091] In this embodiment, the peripheral wall 110 and the anti-fouling plate 120 are provided to collect spilled liquids, splashed oil and water from cooking, etc., generated by the user during cooking, so as to facilitate the cleaning of the burner 200; the vent 113 on the peripheral wall 110 is provided to facilitate the supply of secondary air when the burner 200 is burning; in addition, the opening of the vent 113 is adjustable, which is beneficial to flexibly adjust the amount of secondary air entering according to the combustion situation of the burner 200, so as to achieve complete combustion of the burner 200.
