Abstract
Description
Technical Field
[0001] The present utility model relates to a premixing pipe for mixing gas and air of a gas stove.
Background Art
[0002] At present, there are various types of gas stoves on the market. In order to ensure sufficient oxygen supply during use, some gas stoves are equipped with a blowing device to premix the gas, ensuring sufficient oxygen when the flame burns and a certain gas output pressure, so that the gas stove has the effect of "high heat", which can greatly shorten the cooking time of food. However, at present, the market still uses the traditional ejector pipe for premixing air and gas. Since a blowing device needs to be configured to output air with a certain pressure, the mixing efficiency of air and gas of this traditional ejector pipe structure is relatively low.
[0003] Therefore, it is necessary to make further improvements to it.
Content of the Utility Model
[0004] The purpose of the present utility model is to overcome the above problems. We provide a premixing pipe for mixing gas and air of a gas stove, and this premixing pipe has a relatively high mixing efficiency for mixing gas and air.
[0005] To achieve the above purpose, the present utility model provides a premixing pipe for mixing gas and air of a gas stove, which includes a first pipe body and a second pipe body. The second pipe body is connected to the output end of the first pipe body, and the second pipe body and the first pipe body are arranged perpendicular to each other. The input end of the first pipe body has an air inlet, and the air inlet is used to connect with a blowing device. An air intake is arranged on the pipe wall of the first pipe body, and the air intake is used to input gas. A plurality of side outlets are distributed on the peripheral wall of the output end of the second pipe body.
[0006] In one or more embodiments, the plurality of side outlets are circumferentially distributed on the pipe wall of the second pipe body.
[0007] In one or more embodiments, a plurality of output holes are further distributed on the pipe wall of the second pipe body, and the plurality of output holes are located below the plurality of side outlets.
[0008] In one or more embodiments, an installation step is arranged on the second pipe body, and a plurality of installation holes are distributed on the installation step. The installation step is located below the plurality of output holes.
[0009] In one or more embodiments, the air intake is arranged at a position close to the air inlet, and a threaded connection structure is arranged on the air intake and the air inlet.
[0010] In one or more embodiments, the length of the first pipe body is 6CM - 15CM, and the first pipe body and the second pipe body are fixed by welding.
[0011] In one or more embodiments, the first pipe body and the second pipe body are made of stainless steel.
[0012] The effects of the present utility model compared with the background technology are as follows: The premixing pipe has an air inlet connected to the blowing device and a gas inlet connected to the gas input. Air and gas at a certain pressure are premixed in the first pipe body, and when they are transported to the second pipe body, they are further mixed sufficiently under the hindering effect at the corner position, and finally the mixed gas is output from the second pipe body.
Description of the Drawings
[0013] Figure 1 It is a schematic structural diagram of the high-power gas stove according to the embodiment of the present utility model.
Specific Embodiments
[0014] To deepen the understanding of the present utility model, the following will further elaborate on the present utility model in combination with the embodiments and the drawings. The embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.
[0015] Please refer to the attached Figure 1 , the present utility model provides a premixing pipe for mixing gas and air of a gas stove, which includes a first pipe body 1 and a second pipe body 2. The second pipe body is connected to the output end of the first pipe body. The second pipe body 2 and the first pipe body 1 are arranged perpendicular to each other. The input end of the first pipe body 1 has an air inlet 3, and the air inlet is used to connect to a blowing device. The blowing device can specifically be a blower. An air inlet 4 is arranged on the pipe wall of the first pipe body, and the air inlet is used to input gas. The air inlet is specifically connected to the gas valve output port of the gas stove. A plurality of side output ports 5 are distributed on the circumferential wall of the output end of the second pipe body 2. Specifically, when gas and air are input into the first pipe body together, they will be preliminarily premixed, and then when passing through the corner of the first pipe body and the second pipe body, due to the hindering effect at the corner position, the air and gas collide with each other and are further mixed sufficiently, and then the mixed gas is output from the side output ports on the second pipe body.
[0016] The plurality of side output ports 5 are circumferentially distributed on the pipe wall of the second pipe body 2 and are evenly distributed circumferentially, which helps the mixed gas to be evenly output to the surrounding.
[0017] A plurality of output holes 6 are also distributed on the pipe wall of the second pipe body 2. The plurality of output holes are located below the plurality of side output ports. When the input air pressure increases and the input gas volume increases, in order to avoid the limitation of the output of the mixed gas, the output holes can share the output of the mixed gas and can further ensure that the mixed gas is evenly output to the surrounding.
[0018] An installation step 7 is arranged on the second pipe body 2, and a plurality of installation holes 8 are distributed on the installation step. The installation step is located below the plurality of output holes. The premixing pipe is fixedly hung on the burner head by screwing into the installation holes.
[0019] The air inlet 4 is arranged at a position close to the air inlet 3, and a threaded connection structure is provided on the air inlet and the air inlet, and the provision of the threaded connection structure helps the connection of the gas pipe and the air duct.
[0020] The length of the first pipe body 1 is 6 cm - 15 cm. The first pipe body and the second pipe body are fixed by welding. The lengths of the first pipe body are preferably 8 cm, 10 cm and 13 cm, and are specifically selected according to actual needs. In addition, the first pipe body 1 and the second pipe body 2 may specifically be made of stainless steel.
[0021] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. Any equivalent modifications or changes made by those of ordinary skill in the art according to the disclosure of the present invention shall be included in the protection scope recorded in the claims.
