[0027] The following is a detailed description of the embodiments of the present utility model in conjunction with the accompanying drawings.

[0028] See also Figure 1-Figure 5 The utility model provides a high-efficiency heating device for a heater, which serves as a heat source for the heater and cooperates with a fan to form warm air. The device includes a combustion barrel 3 and a first box body 4.

[0029] A chamber is formed in the combustion barrel 3, which forms a combustion chamber 30 for combustion. A flame hole 301 and a heat exhaust port 302 are provided on the side wall of the combustion chamber 30, wherein the flame hole 301 is used to allow the flame of the burner to enter and burn in the combustion chamber to generate heat and smoke, and the heat exhaust port 302 is used to discharge the high-temperature smoke; a chamber is formed in the first box body 4 to form a first chamber 40, which is connected to the heat exhaust port 302 and can allow the high-temperature smoke generated by the combustion in the combustion chamber 30 to enter, and a first mounting hole 401 is provided on the side wall of the first box body 4, and the first mounting hole 401 is used to install a heat collecting device 5, which is used to absorb heat in the high-temperature smoke and serve as a heat source for the heater. In this embodiment, the combustion barrel 3 or the first box body 4 is made of a heat-conducting material, or The combustion barrel 3 and the first box body 4 are both made of heat-conducting materials, which can be made of stainless steel or aluminum or copper or other heat-conducting metals, which can absorb the heat in the internal fire and smoke, and transfer the heat from the inside to the outside, that is, the outer walls of the combustion barrel 3 and the first box body 4 can dissipate heat to form another heat source, and cooperate with the fan to form warm air. Since the volume of the combustion barrel 3 and the first box body 4 is relatively large, the inner and outer wall areas are also relatively large, the heat absorption and heat release areas are large, the heat absorption and heat release effects are good, the energy utilization rate is high, the heating efficiency is fast, and the fan can quickly form hot air; at the same time, in conjunction with the heat collecting device on the side wall of the first box body 4, the heat in the smoke is further absorbed and released to avoid being discharged with the exhaust gas, which greatly reduces the heat energy loss, improves the energy utilization rate, has low energy consumption, high heating efficiency and good use effect.

[0030] During operation, the temperature of the flue gas located at the center of the first chamber is higher, and the temperature of the flue gas located on both sides is relatively lower, that is, the temperature of the flue gas entering the center of the thermal collector is higher, and the temperature of the flue gas entering the two sides of the thermal collector is relatively lower, resulting in uneven heat distribution and affecting the heat absorption efficiency and effect. In order to solve this problem, in the present application, one or more diverter rods 41 are provided in the first box body 4. The diverter rod 41 is horizontally arranged and is located at the lower end of the first mounting hole (thermal collector assembly). Its length direction is parallel to the connecting direction of the first box body and the second box body. During the rising process of the flue gas, it contacts the diverter rod 41 and disperses to both sides of the diverter rod to achieve diversion and dispersion, that is, the flue gas in the center can be dispersed to both sides, thereby achieving uniform distribution of the flue gas, reducing the temperature difference between the flue gas entering the center and both sides of the thermal collector, and improving the heat absorption efficiency and effect. In this embodiment, the cross section of the combustion barrel 3 is circular. Preferably, it is a cylindrical structure and is arranged horizontally, that is, a horizontal structure is adopted, which can reduce the center of gravity and the installation height, improve the placement stability, and at the same time, can increase the internal combustion area and the effective area of ​​heat absorption; in this application, the front end of the combustion barrel 3 is open (open), forming a heat exhaust port 302, the first box body 4 is fixed to the front end of the combustion barrel 3, and the lower bottom surface of the first box body 4 is flush with the lower bottom surface of the combustion barrel 3, and the bottom surface of the first box body 4 is also arc-shaped, and the combustion barrel 3 and the first box body 4 are connected. The first box body 4 forms an integral structure; the flame hole 301 is opened on the side wall of the first box body 4, and its axis is parallel to the axis of the combustion barrel 3; specifically, it is opened at the end of the first box body 4, and it faces the combustion chamber 30; the top surface of the first chamber 40 is higher than the height of the combustion barrel, so that the high-temperature flue gas can be concentrated into the first chamber, which is convenient for the rapid heat collection of the heat collection device; at the same time, the axial width of the first box body 4 (parallel to the axial direction of the combustion barrel) is smaller than the length of the combustion barrel, so that the flue gas can quickly enter the heat collection device, thereby improving the working efficiency.

[0031] In the present application, an outwardly convex arc cover 31 is provided at the tail of the combustion barrel 3. The inner wall of the arc cover 31 is an arc surface, and its center (center of the sphere) is located in the combustion chamber, preferably, on the axis of the combustion barrel. It plays a certain buffering role during combustion to reduce impact and vibration. At the same time, it can achieve better heat collection and good use effect. Through its heat collection function, it can force the heat in the combustion chamber to quickly enter the first chamber and the heat collection device, thereby improving the overall working efficiency.

[0032] The function of the arc cover 31 is further described below:

[0033] The flame generated by the burner enters the combustion chamber from the flame hole 301 and is sprayed toward the arc hood. The flame is mixed with air (oxygen) and mist fuel (or gas), and has a certain flame impact force. The flame is sprayed toward the center of the arc hood to directly heat the arc hood. Therefore, the temperature of the arc hood is higher than the temperature of the side wall of the combustion barrel, thereby achieving heat concentration. In the combustion process, incomplete combustion may occur, that is, oil gas or carbon monoxide that is not completely burned may rush toward the arc hood with the flame impact force, and gasification may be formed under the high temperature of the arc hood. At the same time, since the inner wall of the arc hood is an arc (spherical) surface, it diffuses to the surroundings under the guidance of the arc surface and flows back along the inner wall of the combustion chamber toward the direction of the fire, thereby having a buffering effect. At the same time, the refluxed flue gas contacts the incoming flame to achieve secondary combustion, thereby making the combustion more complete and the fuel utilization rate high. At the same time, it extends the combustion (flow) distance of the flame or flue gas and increases the overall temperature.

[0034] In order to improve the safety of use and prevent the situation where the pressure and oil and gas in the combustion chamber are too high to form a deflagration when the combustion chamber fails to ignite once under certain conditions, in the present application, a pressure relief pipe 32 is arranged on the side wall of the combustion chamber 30, and a pressure cap 321 is arranged at the end of the pressure relief pipe 32. Under normal combustion conditions, the pressure cap 321 is in a closed state. At this time, the pressure relief pipe is closed and not connected to the outside; when a deflagration or other conditions cause excessive internal pressure, the pressure cap 321 is opened. At this time, the pressure relief pipe is connected to the outside, and the pressure can be released and pressure relief is achieved, thereby improving the safety of use; in the present application, the pressure relief pipe 32 is located at the end away from the heat exhaust port 302, that is, it is arranged at the tail end of the combustion barrel, and it is arranged to be inclined upward.

[0035] In the present embodiment, a second box body 6 is also included. The second box body 6 is located at the upper end of the tail of the combustion barrel and has a certain distance between the first box body and is used to install the heat collecting device 5. A smoke exhaust chamber 60 is provided in the second box body 6. A second mounting hole 602 and a smoke exhaust hole 601 are provided on the side wall of the smoke exhaust chamber 60, wherein the second mounting hole 602 faces the first box body and is used to connect with the air outlet end of the heat collecting device 5. The smoke exhaust hole 601 is provided at the end facing away from the first box body for exhausting smoke, and the air outlet end of the pressure relief pipe 32 is provided in the smoke exhaust chamber 60. Specifically, a hole body is provided at the bottom of the second box body 6, and the hole body is connected to the pressure relief pipe 32. The outlet end of the pressure tube 32 is connected as a pressure relief hole, and the pressure cover 321 is rotatably installed above the pressure relief hole through the shaft body 322. The rotation axis of the pressure cover 321 is parallel to the horizontal plane and perpendicular to the axis of the pressure relief tube 32. At the same time, the shaft body 322 is arranged near one end of the first box body. Under the action of gravity or spring force, the pressure cover 321 can cover the pressure relief hole and form a seal for the pressure relief tube. When the internal pressure is greater than the gravity of the pressure cover or the spring force, the pressure cover 321 opens and realizes pressure relief. In this embodiment, the pressure cover 321 adopts a metal plate structure, which has a certain gravity itself. At the same time, it is resistant to high temperature and has a long service life.
