[0030] The present application provides the following description with reference to the accompanying drawings to help comprehensively understand various embodiments of the present application as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as just exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present application.

[0031] In the description of the present application, the orientation description, such as the orientation or positional relationship indicated by up, down, front, back, left, right, etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0032] It should be understood that when one element (e.g., a first element) is "connected" to another element (e.g., a second element), the element can be directly connected to the other element, or there can be an intervening element (e.g., a third element) between the element and the other element.

[0033] Embodiments of the present application provide a burner assembly, such as Figures 1-2As shown, it comprises an air inlet base 200, a burner 100 and a gas assembly 300. The burner 100 is fixed on the air inlet base 200, which provides support for the burner 100 and keeps the burner 100 stable. The burner 100 comprises a vertically arranged injection pipe 110 and a vertically arranged combustion pipe 120, i.e. the axial direction of the injection pipe 110 and the axial direction of the combustion pipe 120 are parallel to the vertical direction. The lower end of the injection pipe 110 is connected to the air inlet base 200, and the upper end of the injection pipe 110 is connected to the combustion pipe 120. The peripheral surface of the combustion pipe 120 is provided with a plurality of fire holes 121. The gas assembly 300 comprises a nozzle 310 arranged below the injection pipe 110 and facing the injection pipe 110.

[0034] The nozzle 310 can spray gas into the injection pipe 110. Under the action of the airflow, air and gas enter the injection pipe 110 together, then flow to the combustion pipe 120 and mix in the combustion pipe 120. The mixed gas can be sprayed out of the fire holes 121. After ignition, the flame is formed on the outer periphery of the combustion pipe 120. This structure creates conditions for improving the arrangement of the heat exchanger, so that the heat exchanger can be arranged outside the burner 100, and the heat exchanger can more efficiently absorb the heat energy radiated by the burner 100 to the surroundings, which improves the heat exchange efficiency.

[0035] In some embodiments, the air inlet base 200 is provided with an air inlet cavity 210, and the air inlet base 200 is provided with an air inlet communicating with the air inlet cavity 210. External air can enter the air inlet cavity 210 through the air inlet, and then flow to the burner 100. The injection pipe 110 is located at the top of the air inlet base 200, and the lower end of the injection pipe 110 communicates with the air inlet cavity 210. The nozzle 210 is located in the air inlet cavity 210.

[0036] By setting the air inlet cavity 210, the influence of external airflow on the nozzle 210 spraying gas is prevented, ensuring that the gas can be smoothly sprayed into the burner 100. At the same time, the gas is isolated and sealed to avoid gas leakage.

[0037] Further, a blower 400 for blowing air into the air inlet cavity 210 is fixed at the air inlet, and a wind guide structure 410 for guiding the airflow blown by the blower 400 to the injection pipe 110 is arranged in the air inlet cavity 210. The blower 400 can blow air into the air inlet cavity 210, increasing the primary air supply. The wind guide structure 410 guides the air to the injection pipe 110, making the air flow more smoothly to the injection pipe 110. Thus, the present embodiment can increase the primary air supply, make the gas combustion more sufficient, and improve the heat load.

[0038] Furthermore, the top of the air intake seat 200 is provided with multiple secondary air passages 220 that communicate with the air intake chamber 210. The secondary air passages 220 are arranged around the ejector tube 110. Under the action of the air guide structure 410, part of the air blown out by the blower 400 is blown towards the ejector tube 110, and the other part can be blown out from the secondary air passages 220 and then blown towards the outer periphery of the combustion tube 120. This provides secondary air for the combustion of the combustion tube 120, making the combustion of the gas more complete and further improving the heat load.

[0039] In some embodiments, such as Figure 3 As shown, a sealing sleeve 230 is provided on the top of the air inlet seat 200. The sealing sleeve 230 is fitted onto the outside of the burner 100, and the secondary air passage is located on the inside of the sealing sleeve 230. The sealing sleeve 230 acts as a limit and guide for the airflow blown out from the secondary air passage, causing the secondary air to blow upwards and reach the outer periphery of the combustion tube 120 as much as possible. At the same time, the heat exchanger can be fixed to the top of the sealing sleeve 230, which serves as a seal to prevent leakage of fuel gas and / or exhaust gas generated during combustion.

[0040] In this embodiment, the sealing sleeve 230 can be fixedly connected to the top of the air intake seat 200, or the sealing sleeve 230 can be integrally formed with the air intake seat 200.

[0041] In some embodiments, such as Figures 1-2 As shown, the air inlet is located on the side of the air intake seat 200. The air guide structure 410 is an air guide plate that is inclined relative to the horizontal direction. The air guide plate is directly opposite the air outlet of the blower 400. The height of the air guide plate gradually increases in the blowing direction of the blower 400. When the blower 400 blows air outward, the airflow blows onto the air guide plate, then flows upward along the air guide plate, and then guides the airflow to blow towards the ejector pipe 110 at the top of the air intake seat 200.

[0042] This embodiment uses a side-intake air intake method to avoid direct airflow onto the injector tube 110, thus preventing excessively rapid airflow from affecting the fire. Simultaneously, the blower 400 is located on the side of the air intake seat 200, which reduces the overall height of the burner assembly.

[0043] In some embodiments, such as Figure 2 As shown, there are two nozzles 310. The two nozzles 310 simultaneously inject gas into the ejector tube 110, which can increase the gas supply and improve the heat load.

[0044] In some embodiments, such as Figure 1As shown, an ignition needle 130 and a thermocouple 140 are also fixed on the intake seat 200. Both the ignition needle 130 and the thermocouple 140 are close to the combustion tube 120. The ignition needle 130 is used to ignite the gas ejected from the ignition hole to form a flame on the outer periphery of the combustion tube 120. The thermocouple 140 is used to detect the temperature near the combustion tube 120.

[0045] The present invention also provides a heater, including the burner assembly of any of the above embodiments. For a detailed description of the burner assembly, please refer to the above embodiments, which will not be repeated here.

[0046] In some embodiments, such as Figure 4 and Figure 5 As shown, the heater also includes a heat exchanger 500 and a main fan 600. The heat exchanger 500 is installed outside the burner 100, and the air outlet of the main fan 600 faces the heat exchanger 500. Because the heat exchanger 500 is installed outside the burner 100, it can absorb the heat energy radiated by the burner 100 to the surroundings, reduce heat loss, and thus improve heat exchange efficiency.

[0047] Furthermore, the heater also includes a housing 700, and the burner assembly, heat exchanger 500 and main fan 600 are all fixed inside the housing 700. The housing 700 is provided with a heating outlet 710. The air outlet of the main fan 600, the heat exchanger 500 and the heating outlet 710 are arranged sequentially along the air blowing direction of the main fan 600. The heat exchanger 500 absorbs the heat generated by the combustion of the burner 100, thereby heating the air around the heat exchanger 500. The main fan 600 then blows the heated air out through the heating outlet 710 to form hot air for the user to warm up.
