Technical Field
[0001] The utility model belongs to the technical field of gas equipment, and particularly relates to an air inlet device in the shape of a mushroom head. Background Art
[0002] Gas equipment refers to equipment that uses gases such as natural gas and liquefied petroleum gas as fuel sources and converts chemical energy into heat energy or mechanical energy through combustion. Currently, such equipment generally adopts a dedicated air inlet device to ensure efficient operation;
[0003] The existing air inlet device usually supplies gas through an external gas supply pipe, and then mixes with the surrounding air through a plurality of air ports arranged in a ring. Although the air intake effect can be achieved, such a single layout of the air hole design limits the gas intake volume, resulting in a decrease in the mixing efficiency of gas and air, and further affecting the combustion efficiency and stability. Summary of the Utility Model
[0004] In view of this, the utility model provides an air inlet device in the shape of a mushroom head, which can greatly increase the gas intake volume through the double-air-hole design layout formed by the cooperation of the first air holes and the second air holes, helps the gas and air to be more evenly mixed, realizes the effective mixing and supply of gas and air, promotes the combustion efficiency and stability, can effectively block the waste ash formed by combustion, and ensures the long-term reliable operation of the equipment.
[0005] To solve the above technical problems, the utility model provides an air inlet device in the shape of a mushroom head, which includes a mushroom head, a plurality of first air holes and a plurality of second air holes respectively arranged on the inner core of the mushroom head. The plurality of second air holes are all located below the plurality of first air holes. A plurality of air inlets are provided at the bottom edge of the mushroom head, and a connecting pipe is arranged in the gas inlet at the center of the bottom of the mushroom head. A dust-proof member for blocking waste ash is arranged at the lower end of the connecting pipe. That is, through the double-air-hole design layout of the first air holes and the second air holes, the gas intake volume is greatly increased, which helps the gas and air to be more evenly mixed, realizes the effective mixing and supply of gas and air, and promotes the combustion efficiency and stability.
[0006] The plurality of first air holes and the plurality of second air holes are both arranged in a circular array, which helps the gas and air to be quickly and evenly mixed in the mushroom head.
[0007] The plurality of first air holes and the plurality of second air holes are staggered one by one in the circumferential direction, so that the gas can be evenly distributed when entering.
[0008] The diameters of the plurality of second air holes are all larger than the diameters of the plurality of first air holes, that is, the flow rate of the lower-layer gas is increased, which is beneficial to forming a stable and sufficient premixed gas.
[0009] The dust-proof component includes a dust-proof ring disposed at the bottom of the connecting pipe, which can effectively block the waste ash formed by combustion.
[0010] The dust-proof ring is integrally cast with the connecting pipe, which enhances the sealing performance and durability of both.
[0011] Internal threads are provided at the bottom of the inner arc surface of the connecting pipe. That is, by screwing with the external gas pipeline through the internal threads, the stable connection of the gas pipeline is ensured.
[0012] The beneficial effects of the above technical solutions of the present utility model are as follows:
[0013] 1. First, the connecting pipe is threadedly connected to the air supply port of the external gas pipeline through the internal threads, so that the two are connected. When the device starts to work, external air is naturally inhaled through multiple air inlets at the bottom edge of the mushroom head or forced to be introduced under the action of an external auxiliary fan. After the air enters, a certain flow field distribution will be formed inside the mushroom head. At this time, the gas enters the connecting pipe through the air supply port of the external gas pipeline, and then enters the mushroom head through the connecting pipe and the gas inlet at the bottom center of the mushroom head. During this process, since the first air holes and the second air holes are arranged in a circumferential array and are staggered one by one, such a design layout of the double air holes greatly increases the gas intake volume, helps the gas and air to be more evenly mixed, realizes the effective mixing and supply of the gas and air, and promotes the combustion efficiency and stability.
[0014] 2. The dust-proof ring can effectively block the waste ash formed by combustion. The design of integrally casting the dust-proof ring with the connecting pipe further enhances its sealing performance and durability, ensuring the long-term reliable operation of the device.

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the accompanying drawings of the embodiments of the present utility model will be combined below. Figures 1-3, the technical solutions of the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all embodiments. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by the present utility model.
[0020] As Figures 1-3 shown:
[0021] This embodiment provides an air intake device in the shape of a mushroom head, including a mushroom head 100 and a plurality of first air holes 101 and a plurality of second air holes 102 respectively arranged on the inner core of the mushroom head 100. The plurality of first air holes 101 and the plurality of second air holes 102 are both inclined downward from outside to inside. The plurality of first air holes 101 and the plurality of second air holes 102 form a design layout of double air holes, greatly improving the air intake volume of the gas. The plurality of second air holes 102 are all located below the plurality of first air holes 101. A plurality of air inlets 103 are provided at the bottom edge of the mushroom head 100. External air can be naturally inhaled through the plurality of air inlets 103 at the bottom edge of the mushroom head 100 or be forced to be introduced under the action of an external auxiliary fan. A connecting pipe 104 is provided in the gas inlet at the bottom center of the mushroom head 100 for transmitting the gas. A dust-proof member for blocking waste ash is provided at the lower end of the connecting pipe 104.
[0022] When the device starts to work, external air is naturally inhaled through the plurality of air inlets 103 at the bottom edge of the mushroom head 100 or is forced to be introduced under the action of an external auxiliary fan. After the air enters, a certain flow field distribution will be formed inside the mushroom head 100. At this time, the gas enters the connecting pipe 104 through the gas supply port of the external gas pipeline, and enters the inside of the mushroom head 100 through the connecting pipe 104 and the gas inlet at the bottom center of the mushroom head 100. During this process, due to the design layout of the double air holes of the first air holes 101 and the second air holes 102, the air intake volume of the gas is greatly improved, which helps the gas and air to be more evenly mixed, realizing the effective mixing and supply of the gas and air, and promoting the combustion efficiency and stability.
[0023] As Figures 1-2 shown, the plurality of first air holes 101 and the plurality of second air holes 102 are both arranged in a circular array, which helps the gas and air to be quickly and evenly mixed inside the mushroom head 100.
[0024] As Figures 1-2 shown, the plurality of first air holes 101 and the plurality of second air holes 102 are staggered one by one in the circumferential direction, so that the gas can be evenly distributed when entering.
[0025] As Figures 1-2As shown, the diameters of multiple second air holes 102 are all larger than those of multiple first air holes 101, which can increase the flow rate of the lower-layer gas and is conducive to forming a stable and sufficient premixed gas.
[0026] As Figures 1-3 shown, the dust-proof part includes a dust-proof ring 200 arranged at the bottom of the connecting pipe 104. The overall formed by the connecting pipe 104 and the dust-proof ring 200 is in a horn shape, which can effectively block the waste ash formed by combustion.
[0027] As Figures 1-3 shown, the dust-proof ring 200 and the connecting pipe 104 are integrally cast, enhancing the sealing performance and durability of both.
[0028] As Figure 3 shown, an internal thread 300 is provided at the bottom of the inner arc surface of the connecting pipe 104. The internal thread 300 is in threaded engagement with the external gas pipeline, thereby ensuring the stable connection of the gas circuit.
[0029] The working principle of a mushroom-shaped air intake device provided by the present utility model is as follows: First, it is threadedly connected to the air supply port of the external gas pipeline through the internal thread 300 to connect the two. When the device starts to work, external air is naturally inhaled through multiple air intake holes 103 at the bottom edge of the mushroom head 100 or is forced to be introduced under the action of an external auxiliary fan. After the air enters, a certain flow field distribution will be formed inside the mushroom head 100. At this time, the gas enters the connecting pipe 104 through the air supply port of the external gas pipeline and enters the mushroom head 100 through the gas intake hole at the bottom center of the connecting pipe 104 and the mushroom head 100. During this process, since the first air holes 101 and the second air holes 102 are arranged in a circumferential array and are staggered one by one, such a design layout of the double air holes greatly increases the gas intake volume, helps the gas and air to be more evenly mixed, realizes the effective mixing and supply of the gas and air, promotes the combustion efficiency and stability. The diameter of the second air hole 102 is larger than that of the first air hole 101, which can increase the flow rate of the lower-layer gas and is conducive to forming a stable and sufficient premixed gas. The dust-proof ring 200 can effectively block the waste ash formed by combustion, and the design of integrally casting the dust-proof ring 200 and the connecting pipe 104 further enhances its sealing performance and durability, ensuring the long-term reliable operation of the device.
[0030] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0031] The above are the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
