DETAILED DESCRIPTION

[0027] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0028] The following is combined with Figure 1-4 This application is described in further detail. Example

[0029] Please refer to Figure 1-4 The present embodiment provides a small infrared radiation burner, including an air delivery device, a natural gas delivery device, a burner, an ignition device and a controller 1. The burner includes a combustion tube and a combustion head 2. The combustion head 2 is a tubular structure. One end of the combustion head 2 extends into the combustion tube, and the other end is connected to the natural gas delivery device. At least one first air inlet hole 3 is opened in the circumference of the combustion head 2. The air delivered by the air delivery device can enter the combustion head 2 through the first air inlet hole 3. At least one second air inlet hole 4 is opened on the combustion tube. The air delivery device can deliver air to the combustion tube through the second air inlet hole 4. The natural gas delivery device and the air delivery device are both electrically connected to the controller 1, and the combustion head 2 is connected to the controller 1 through the ignition device.

[0030] In this embodiment, the air delivery device is used to deliver air to the inside of the burner to provide oxygen supply for the combustion of natural gas. The natural gas delivery device is used to deliver natural gas to the inside of the burner. When air and natural gas are delivered into the burner at the same time, a mixed gas is formed. At this time, the controller 1 can be operated to control the ignition device, and the mixed gas is ignited for combustion.

[0031] According to Bernoulli's principle, when the flow is constant, the greater the flow rate of the fluid, the smaller the pressure. When the high-pressure natural gas is transported into the burner by the natural gas delivery device, when the high-pressure natural gas flows through the first air inlet 3 opened on the burner head 2, due to the high flow rate of the natural gas, the pressure inside the burner head 2 at the first air inlet 3 is less than the pressure outside the burner head 2. Therefore, when the wind delivered by the air delivery device flows to the first air inlet 3, under the action of the pressure difference, the air can enter the burner head 2 from the first air inlet 3 under the "drive" of the high-pressure natural gas, mix with the natural gas for the first time, and then burn. In this process, the excess mixed gas will flow from the burner head 2 into the combustion tube, and at the same time, the wind delivered by the air delivery device can enter the combustion tube through the second air inlet 4, and mix with the unburned mixed gas for the second time to further increase the oxygen content of the mixed gas, and then fully burn in the combustion tube. The number of the first air inlet 3 and the second air inlet 4 can be increased as needed.

[0032] Furthermore, in the utility model, the combustion tube includes an outer cylinder 5 and an inner cylinder 6 coaxially arranged in the outer cylinder 5, a combustion chamber is formed between the inner cylinder 6 and the outer cylinder 5, one end of the combustion head 2 extends into the inner cylinder 6, the second air inlet 4 is located at the end of the inner cylinder 6 close to the combustion head 2, and the end of the outer cylinder 5 away from the combustion head 2 is sealed.

[0033] In the present embodiment, the combustion tube is designed with this structure, which can increase the combustion area of ​​the burner on the one hand, that is, the mixed gas in the combustion head 2 can also flow into the combustion tube for combustion, so that the burner can burn more natural gas under the same oxygen supply; on the other hand, the wind delivered by the air delivery device enters the combustion tube through the second air inlet 4, which can further increase the oxygen content of the mixed gas and make the combustion more complete.

[0034] Furthermore, in the present invention, the air conveying device includes a centrifugal fan 7 and a wind pressure sensor 8 disposed on the centrifugal fan 7 , and the wind pressure sensor 8 is electrically connected to the controller 1 .

[0035] In this embodiment, the centrifugal fan 7 is used to deliver air to the burner. The wind pressure sensor 8 is used to feed back the working status of the centrifugal fan 7 to the controller 1. Specifically, when the centrifugal fan 7 is turned on, fresh air is supplied to the small burner, and the signal of the normal operation of the centrifugal fan 7 is detected by the wind pressure sensor 8, which then transmits the signal to the controller 1. While the centrifugal fan 7 is operating normally, the natural gas delivery device also starts to work, delivering natural gas to the combustion head 2. The controller 1 then controls the ignition device to perform the ignition action, and the mixed gas formed by the air and natural gas can be burned.

[0036] Furthermore, in the present invention, the natural gas transmission device includes a gas pipeline 9 and a solenoid valve 10 arranged on the gas pipeline 9, the gas pipeline 9 is connected to one end of the burner head 2 away from the inner cylinder 6, and the solenoid valve 10 is electrically connected to the controller 1.

[0037] In this embodiment, the gas pipeline 9 can be connected to an external gas transmission device to transmit natural gas to the burner head 2. The solenoid valve 10 installed on the gas pipeline 9 is used to control the flow of the gas pipeline 9.

[0038] Furthermore, in the present invention, the ignition device is an ignition needle 11 , one end of the ignition needle 11 is electrically connected to the controller 1 , and the other end extends into the combustion head 2 .

[0039] In this embodiment, the ignition device adopts an ignition needle 11 with a needle structure, one end of which is convenient for extending into the combustion head 2, and then an ignition action is realized under the control of the controller 1 to ignite the combustion head 2.

[0040] Furthermore, in the present invention, a flame sensing sensor is also included which is arranged on the combustion head 2 , and the flame sensing sensor is electrically connected to the controller 1 .

[0041] In this embodiment, the flame sensor is used to detect the flame state in the combustion head 2 and transmit the signal value to the controller 1. If the flame state is normal, the solenoid valve 10 and the centrifugal fan 7 continue to operate, and the system operates normally; if the flame state is abnormal, that is, no flame is detected, the abnormal signal is immediately transmitted to the controller 1, and the controller 1 controls the ignition needle 11 to re-ignite.

[0042] Furthermore, in the present invention, the flame sensing sensor is a flame sensing needle 12 , one end of the flame sensing needle 12 is electrically connected to the controller 1 , and the other end extends into the burner head 2 .

[0043] In this embodiment, the flame sensing sensor adopts a probe type sensor, which is convenient for one end to be inserted into the combustion head 2 for detection. Specifically, the flame sensing needle 12 is an instrument for detecting flames, which mainly determines the existence of flames by sensing the electrical signal generated by the change of gas around the flame.

[0044] Furthermore, in the utility model, it also includes a shell 13, the burner is installed on the shell 13, a receiving chamber 14 is formed in the shell 13, the air inlet end of the burner is located in the receiving chamber 14, and the air outlet of the centrifugal fan 7 is connected to the receiving chamber 14.

[0045] In this embodiment, the housing 13 can be used to install various parts of the burner for easy transportation and storage. The accommodating chamber 14 in the housing 13 facilitates the flow of wind delivered by the centrifugal fan 7 to the combustion head 2. The burner is installed on the housing 13, and a part of it is exposed to the outside for easy heat dissipation. In addition, a handle 16 can be installed on the housing 13 for easy transportation.

[0046] Furthermore, in the present invention, a one-way valve is provided at the air outlet of the centrifugal fan 7 in the shell 13, and the wind generated by the centrifugal fan 7 flows through the one-way valve and the accommodating chamber 14 in sequence and can be respectively delivered to the combustion head 2 and the combustion tube.

[0047] In this embodiment, a one-way valve is provided at the air outlet of the centrifugal fan 7 so that the wind energy generated by the centrifugal fan 7 can enter the accommodating chamber 14. When the centrifugal fan 7 is not working, the airflow and / or dust in the accommodating chamber 14 cannot enter the centrifugal fan 7.

[0048] Furthermore, in the present utility model, the one-way valve is a one-way wind shield plate 15 hingedly arranged in the housing 13 , and the one-way wind shield plate 15 can block the air outlet of the centrifugal fan 7 .

[0049] In this embodiment, the one-way valve adopts this structure to realize the one-way wind shielding function. Specifically, when the centrifugal fan 7 works normally, the wind generated by it has a certain thrust. When this thrust acts on the one-way wind shield 15, since the one-way wind shield 15 is hinged with the shell 13, the wind with a certain thrust can push the one-way wind shield 15 to rotate, and the air outlet of the centrifugal fan 7 can be opened, and the wind will flow into the accommodating chamber 14. When the centrifugal fan 7 stops working, the one-way wind shield 15 can be in a suspended state or other state under the action of gravity, as long as the air outlet of the centrifugal fan 7 can be blocked. At this time, the airflow in the accommodating chamber 14 cannot enter the centrifugal fan 7 through the air outlet of the centrifugal fan 7, or flow to other positions. The one-way wind shield 15 can be installed at the air outlet of the centrifugal fan 7 by hinge connection, pin shaft and pin hole connection, etc.

[0050] When in use, start the centrifugal fan 7, and the signal of the normal operation of the centrifugal fan 7 will be detected by the wind pressure sensor 8, and the wind pressure sensor 8 will then transmit the signal to the controller 1. While the centrifugal fan 7 is operating normally, the natural gas delivery device also starts to work, delivering natural gas to the combustion head 2. The controller 1 then controls the ignition device to perform the ignition action, and the mixed gas formed by the air and natural gas can be burned. During the combustion of the mixed gas, if the flame state is normal, the solenoid valve 10 and the centrifugal fan 7 will continue to operate, and the system will operate normally; if the flame state is abnormal, that is, the flame sensing needle 12 does not detect the flame, this abnormal signal will then be transmitted to the controller 1, and the controller 1 will control the ignition needle 11 to re-ignite and re-ignite the mixed gas. When not in use, turn off the centrifugal fan 7, the solenoid valve 10, the ignition device and various sensors.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
