Description

Technical Field

[0001] This utility model relates to the field of stove head technology, and in particular to a water-blocking stove head. Background Technology

[0002] A stove is a common kitchen appliance. Inside the stove is an ignition needle used to ignite a small flame. The ignition needle is usually made of high-temperature resistant ceramic and fixed inside the stove. However, existing ignition needles do not have any shielding or protection. During use, chefs often need to add water while cooking. The chef's action of scooping water with a spoon is usually fast and large, and cold water can easily splash onto the stove outside the pan. The ceramic is fixed close to the flame and has a high temperature under prolonged high-temperature conditions. When cold water suddenly splashes onto the ceramic, the ceramic is suddenly cooled and is prone to cracking and damage. Utility Model Content

[0003] To address the aforementioned problems, this utility model aims to provide a water-blocking burner head to solve the issue of water easily splashing onto the ignition needle, causing damage to the ceramic that holds the ignition needle in place.

[0004] The technical problem solved by this utility model can be achieved by the following technical solution: a water-blocking stove head, including a stove head body, a water-blocking cover, an ignition needle, a sensing needle, and a fixed ceramic. An ignition needle and a sensing needle are provided on the inner side wall of the stove head body. The sensing needle is located on one side of the ignition needle. Both the ignition needle and the sensing needle are fixed on the fixed ceramic. A water-blocking cover is provided above the fixed ceramic. A combustion hole is provided on the water-blocking cover.

[0005] The fixing ceramic is fixed inside the steel sleeve, which penetrates the furnace head body from the side. The fixing ceramic passes through the steel sleeve, and the upper end of the fixing ceramic extends out of the upper outlet of the steel sleeve.

[0006] The center of the water-blocking cover protrudes upwards, and the combustion holes are distributed around the protrusion.

[0007] The inner wall of the burner body is provided with a placement step, and the edge of the water baffle is placed on the placement step.

[0008] The burner body includes a flame cap and a mixing chamber shell. The flame cap is positioned above the mixing chamber shell, and the bottom surface of the flame cap and the mixing chamber shell form a mixing chamber. A first air outlet is provided on the upper part of the flame cap, which is connected to the mixing chamber. A small flame tube is inserted through the center of the flame cap and the mixing chamber shell. A small flame air supply hole is provided on the side of the small flame tube, which is connected to the mixing chamber. An air inlet pipe is connected to the side of the mixing chamber shell, and a main air inlet is provided at the lower part of the air inlet pipe.

[0009] The upper end of the small flame tube is provided with a flame cap, and the side of the flame cap is provided with a second vent hole, which is connected to the small flame tube.

[0010] The side of the burner cap is provided with a make-up air and drain pipe, the upper end of which is located on one side of the second air outlet. The air inlet pipe is provided with a make-up air interface, which is connected to the side of the make-up air and drain pipe through a pipe.

[0011] Compared with the prior art, this utility model has the following advantages: This utility model sets a water baffle above the ceramic fixing ignition needle and the burner cap to block the cold water splashing from above during use. The water baffle will block the cold water splashing from above and will not directly splash onto the ceramic fixing ignition needle and the burner cap, preventing the ceramic from cracking due to sudden cooling and improving the service life of the burner head. The water accumulated in the burner head can also be discharged through the air supply and drainage pipe. Attached Figure Description

[0021] Combined with appendix Figures 1 to 6 As shown, this embodiment discloses a water-blocking stove head, including a stove head body, a water-blocking cover 8, an ignition needle 6, a sensing needle 7, and a fixed ceramic 5. The ignition needle 6 and the sensing needle 7 are provided on the inner side wall of the stove head body. The sensing needle 7 is located on one side of the ignition needle 6. The ignition needle 6 and the sensing needle 7 are fixed on the fixed ceramic 5. The water-blocking cover 8 is provided above the fixed ceramic 5. The water-blocking cover 8 is provided with combustion holes 9. The center of the water-blocking cover 8 protrudes upward, and the combustion holes 9 are distributed around the protrusion.

[0022] The burner head body includes a burner cap 2 and a mixing chamber shell 1. The burner cap 2 is positioned above the mixing chamber shell 1, and its bottom surface and the mixing chamber shell 1 form a mixing chamber 10. A first air outlet 11 is provided on the upper part of the burner cap 2, which is connected to the mixing chamber 10. An air inlet pipe 4 is connected to the side of the mixing chamber shell 1, and a main air inlet 14 is provided at the lower part of the air inlet pipe 4. A flame suppressor cap 13 is provided at the upper end of the small flame tube 3, and a second air outlet 12 is provided on the side of the flame suppressor cap 13, which is connected to the small flame tube 3. A small flame tube 3 is inserted through the center of the burner cap 2 and the mixing chamber shell 1. Four small flame air supply holes 18 are provided on the side of the small flame tube 3, which are connected to the mixing chamber 10. In use, the air introduced by the air inlet pipe 4 enters the small flame tube 3 through the small flame air supply holes 18 to supply air, ensuring that the small flame is upward.

[0023] The fixing ceramic 5 is fixed inside the steel sleeve 17. The steel sleeve 17 penetrates the burner body from the side. The upper end of the steel sleeve 17 is located above the fire cover 2. The fixing ceramic 5 passes through the steel sleeve 17, and the upper end of the fixing ceramic 5 extends out of the upper outlet of the steel sleeve 17.

[0024] A make-up air and drain pipe 15 is provided on the side of the burner cap 2. The upper end of the make-up air and drain pipe 15 is located on one side of the second air outlet 12. A make-up air interface 16 is provided on the air inlet pipe 4. The make-up air interface 16 is connected to the side of the make-up air and drain pipe 15 through a pipe to make up air. When in use, a pot is placed on top of the burner. When the pot is placed on top, the flame will jump down. Unburned gas may also leak out from the make-up air and drain pipe 15. By making up air through the make-up air and drain pipe 15, the flame will not fall down and unburned gas will be prevented from being discharged from the make-up air and drain pipe 15. Water that falls into the burner during use can be discharged through the make-up air and drain pipe 15.

[0025] The inner wall of the fire cover 2 is provided with a placement step, and the edge of the water-blocking cover 8 is placed on the placement step.

[0026] In use, gas enters the lower end of the small burner tube 3, and air enters the small burner air inlet 18 on the side. The gas mixture of gas and air exits from the second air outlet 12. The ignition needle 6 ignites the gas from the side of the outlet of the small burner tube 3. Air enters through the air inlet 4, and gas enters through the main air inlet 13. The two are mixed in the mixing chamber 10 and then pass through the first air outlet 11 to the upper part of the burner cap 2 for combustion. A water baffle 8 is installed above the ceramic 5 that fixes the ignition needle 6 to block cold water splashing from above during use. The water baffle 8 will block the cold water splashing from above and will not directly spray onto the ceramic 5 that fixes the ignition needle 6, thus preventing the ceramic 5 from cracking due to sudden cooling.

[0027] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
