Description

Technical Field

[0001] This utility model relates to the field of stove technology, and in particular to an outdoor heating stove. Background Technology

[0002] When camping or working outdoors in cold weather, outdoor heaters are often needed for warmth. Existing outdoor heaters, as shown in patent application number CN202322189915.9, include a furnace body, a combustion rack, and a glass cover. The combustion rack is located in the furnace body, and the glass cover is located at the top of the furnace body. When the above-mentioned outdoor heater is in use, pellet fuel is placed in the combustion rack and ignited. Air enters the furnace body from the bottom to provide oxygen, and the exhaust gas from the combustion is discharged upward through the glass cover.

[0003] Existing heating stoves have the following disadvantages: First, the pellet fuel is burned by natural wind, resulting in a small flame and poor heating effect; second, the exhaust gas passes through a glass cover, which is very hot and can easily burn users. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of existing heating stoves, this utility model proposes an outdoor heating stove that improves the heating effect and is less likely to scald users.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An outdoor heating stove includes a stove body, a combustion rack, a fan, and a glass cover. An air inlet is provided at the lower end of the stove body. The combustion rack includes a cylinder and a combustion mesh installed in the cylinder. The cylinder is vertically arranged in the stove body, and a first air duct is formed between the cylinder and the stove body. The glass cover includes an inner glass tube, an outer glass tube, and a fixing key. The outer glass tube is fixedly connected to the outside of the inner glass tube by the fixing key. A second air duct is formed between the inner glass tube and the outer glass tube. The lower end of the outer glass tube rests on the upper end of the stove body, and the lower end of the inner glass tube is located on the outer side of the upper end of the cylinder. The upper end of the first air duct is connected to the lower end of the second air duct. The fan is located at the lower end of the cylinder and blows air to the cylinder and the lower end of the first air duct.

[0006] Through the above settings, firstly, the glass cover adopts a double-layer design to reduce the surface temperature of the glass cover and prevent burns; secondly, a first air duct and a second air duct are formed on the inner side of the furnace body and the glass cover respectively, further reducing the temperature of the outer side of the furnace body and the glass cover; thirdly, the fan blows air upwards to improve the combustion efficiency of the pellet fuel in the combustion rack, resulting in a larger flame, which enhances the aesthetics while improving the heating effect.

[0007] Furthermore, the heating furnace also includes a support frame, which includes a duct and a support plate. The duct is vertically fixedly connected to the furnace body, with the lower end of the duct higher than the air inlet. The fan is installed in the duct. The support plate is fixedly connected to the outer side of the upper end of the duct. The lower end of the cylinder is fitted onto the upper end of the duct and rests on the support plate. The upper end is provided with an air outlet that communicates with the lower end of the first air duct.

[0008] With the above setup, the blower is installed in the furnace body via a bracket.

[0009] Furthermore, the support also includes a baffle plate, which is horizontally fixed to the upper end of the air duct. There is a gap between the baffle plate and the air duct, and the horizontal projection of the baffle plate covers the horizontal projection of the fan.

[0010] The above settings prevent ash from the combustion of pellet fuel from falling onto the wind turbine and affecting its safety.

[0011] Furthermore, the combustion frame also includes an ash collection mesh, which is located below the combustion mesh and fixedly connected to the lower end of the cylinder.

[0012] The above settings further prevent ash from falling onto the fan.

[0013] Furthermore, the combustion rack also includes an annular baffle, which is located below the ash collection mesh and fixedly connected to the lower end of the cylinder. The inner diameter of the annular baffle is smaller than the outer diameter of the baffle plate.

[0014] The above settings further prevent ash from falling onto the fan.

[0015] Furthermore, the combustion frame also includes multiple bolts, which are circumferentially mounted on the cylinder with the ends of the bolts protruding from the inner wall of the cylinder. The edge of the combustion mesh rests on the bolts, and the combustion frame also includes a pull ring fixedly connected to the upper side of the combustion frame.

[0016] The above setup makes it easy to remove the combustion screen for cleaning and prevents it from becoming clogged.

[0017] Furthermore, the heater also includes a reflector assembly, which includes an air outlet sleeve, a connecting rod, and a reflector plate. An annular groove is provided along the outer periphery of the upper end of the outer glass tube, and the lower edge of the air outlet sleeve is inserted into the annular groove. The reflector plate is fixedly connected to the air outlet sleeve by the connecting rod, and the upper end of the inner glass tube is lower than the upper end of the outer glass tube.

[0018] The above settings further enhance the heating effect. Attached Figure Description

[0025] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0026] like Figures 1 to 6 An outdoor heating stove includes a stove body 3, a combustion rack, a fan 4, and a glass cover 5. The lower end of the stove body 3 is provided with an air inlet 6. The combustion rack includes a cylinder 7 and a combustion mesh 8 installed in the cylinder 7. The cylinder 7 is vertically arranged in the stove body 3, and a first air duct 9 is formed between the cylinder 7 and the stove body 3. The glass cover 5 includes an inner glass tube 51, an outer glass tube 52, and a fixing key 53. The outer glass tube 52 is fixedly connected to the outside of the inner glass tube 51 by the fixing key 53. A second air duct 10 is formed between the inner glass tube 51 and the outer glass tube 52. The lower end of the outer glass tube 52 rests on the upper end of the stove body 3, and the lower end of the inner glass tube 51 is located on the outer side of the upper end of the cylinder 7. The upper end of the first air duct 9 is connected to the lower end of the second air duct 10. The fan 4 is located at the lower end of the cylinder 7 and blows air to the lower end of the cylinder 7 and the first air duct 9.

[0027] Through the above settings, firstly, the glass cover 5 adopts a double-layer design to reduce the surface temperature of the glass cover 5 and prevent burns; secondly, a first air duct 9 and a second air duct 10 are formed on the inner side of the furnace body 3 and the glass cover 5 respectively, further reducing the outer temperature of the furnace body 3 and the glass cover 5; thirdly, the fan 4 blows air upward to improve the combustion efficiency of the particulate fuel in the combustion rack, resulting in a larger flame, which enhances the aesthetics while improving the heating effect.

[0028] The furnace body 3 of this application is basically cylindrical in shape, with an open top for easy placement of the combustion rack. Within the combustion rack, the cylindrical body 7 is a cylindrical structure, placed vertically within the furnace body 3, and coaxially aligned with it. The combustion mesh 8 is a circular mesh structure made of metal with high-temperature resistance, horizontally installed in the middle of the cylindrical body 7. Pellet fuel is fed into the cylindrical body 7 from the top, and the combustion mesh 8 supports the pellet fuel. The glass cover 5 is cylindrical, with its outer surface flush with the outer surface of the cylindrical body 7 for aesthetic appeal. A blower 4 is installed at the lower end of the furnace body 3. The blower 4 can be powered by an external power source or a battery. Specifically, the blower 4 includes a motor and blades. The motor is fixedly installed at the lower end of the furnace body 3, with its output axis pointing upwards and aligned with the furnace body 3. The blades are connected. When the motor drives the blades, outside air enters the furnace body 3 through the air inlet 6. Under the action of the blades, part of the airflow flows through the cylinder 7 and the combustion net 8 to the pellet fuel, which helps the pellet fuel to burn, increases its flame height and combustion efficiency. Users can see the flame through the glass cover 5. The heating furnace provides lighting function and improves the heating effect. The exhaust gas generated by the combustion of pellet fuel is discharged to the outside atmosphere from the upper end of the inner glass tube 51. Another part of the airflow passes through the first air duct 9 and the second air duct 10 and is discharged upward to the outside atmosphere. When the airflow passes through the first air duct 9, it absorbs the heat of the furnace body 3 and helps to reduce the temperature of the furnace body 3. When the airflow passes through the second air duct 10, it absorbs the heat of the outer glass tube 52 and helps to reduce the temperature of the outer glass tube 52.

[0029] As one implementation method, the heating furnace also includes a support frame, which includes a duct 11 and a support plate 12. The duct 11 is vertically fixed inside the furnace body 3, and the lower end of the duct 11 is higher than the air inlet 6. The fan 4 is installed in the duct 11. The support plate 12 is fixedly connected to the outer side of the upper end of the duct 11. The lower end of the cylinder 7 is fitted onto the upper end of the duct 11 and rests on the support plate 12. The upper end is provided with an air outlet 13 that communicates with the lower end of the first air duct 9.

[0030] With the above setup, the blower 4 is installed in the furnace body 3 via a bracket.

[0031] In this application, the air duct 11 is coaxially and fixedly connected to the lower end of the furnace body 3. Specifically, the middle part of the air duct 11 is fixedly connected to the furnace body 3 via a connecting plate. The lower end of the air duct 11 is higher than the air inlet 6, facilitating the upward delivery of outside air through the air inlet 6 and the air duct 11. Part of the airflow flows through the upper end of the air duct 11 into the pellet fuel in the cylinder 7, and another part of the airflow flows through the air outlet 13 into the first air duct 9, and then upward through the second air duct 10 to be discharged to the outside atmosphere. Figure 3 As shown.

[0032] As one implementation, the bracket also includes a baffle 14, which is horizontally fixed to the upper end of the air duct 11. There is a gap between the baffle 14 and the air duct 11, and the horizontal projection of the baffle 14 covers the horizontal projection of the fan 4.

[0033] The above settings prevent ash from the combustion of pellet fuel from falling onto the fan 4 and affecting its safety.

[0034] The baffle 14 of this application has a disc-shaped structure and is horizontally fixedly connected to the upper end of the air duct 11. The horizontal projection of the baffle 14 covers the horizontal projection of the blower 4, and the baffle 14 can completely cover the blower 4. When the pellet fuel is burned, it produces ash. If any ash falls through the combustion net 8, the ash will fall onto the baffle 14 and will not fall onto the blower 4, thus protecting the blower 4. There is a gap between the edge of the baffle 14 and the air duct 11. When the blower 4 blows air upward, the airflow can bypass the edge of the baffle 14 and move upward along the cylinder 7 to aid the combustion of the pellet fuel.

[0035] As one implementation, the combustion rack also includes an ash collection net 15, which is located below the combustion net 8 and fixedly connected to the lower end of the cylinder 7.

[0036] The above settings further prevent ash from falling onto fan 4.

[0037] The aperture of the ash-collecting mesh 15 in this application is smaller than that of the combustion mesh 8. When ash falls from the combustion rack, the ash-collecting mesh 15 can catch the ash and prevent it from falling further down onto the blower 4. When the blower 4 is running, the airflow can flow upward through the ash-collecting mesh 15 to aid the combustion of the pellet fuel.

[0038] As one implementation, the combustion rack also includes an annular baffle 16, which is disposed on the lower side of the ash collection mesh 15 and fixedly connected to the lower end of the cylinder 7. The inner diameter of the annular baffle 16 is smaller than the outer diameter of the baffle plate 14.

[0039] The above settings further prevent ash from falling onto fan 4.

[0040] The annular baffle 16 of this application is disposed between the ash receiving screen 15 and the baffle plate 14. When ash falls from the ash receiving screen 15, the annular baffle 16 can block part of the ash and prevent the ash from falling onto the ash through the gap between the baffle plate 14 and the air duct 11.

[0041] As one implementation, the combustion frame also includes a plurality of bolts 17, which are circumferentially mounted on the cylinder 7. The ends of the bolts 17 protrude from the inner wall of the cylinder 7. The edge of the combustion mesh 8 rests on the bolts 17. The combustion frame also includes a pull ring 18 fixedly connected to the upper side of the combustion frame.

[0042] The above settings make it easy to remove the combustion mesh 8 for cleaning and prevent the combustion mesh 8 from becoming clogged.

[0043] As one implementation, the heater also includes a reflector assembly 19, which includes an air outlet sleeve 191, a connecting rod 192, and a reflector plate 193. An annular groove 20 is provided along the outer periphery of the upper end of the outer glass tube 52, and the lower edge of the air outlet sleeve 191 is stuck in the annular groove 20. The reflector plate 193 is fixedly connected to the air outlet sleeve 191 through the connecting rod 192. The upper end of the inner glass tube 51 is lower than the upper end of the outer glass tube 52.

[0044] The above settings further enhance the heating effect.

[0045] like Figure 6 The lower edge of the air outlet sleeve 191 is locked in the annular groove 20 to prevent the air outlet sleeve 191 from moving left and right; the reflector 193 is made of silver material and has good heat reflection performance. The heat radiation of the flame is reflected by the reflector 193 and then radiates to the surroundings, which is convenient for heating the surrounding users; when the fan 4 blows air upward, the airflow in the cylinder 7 bypasses the reflector 193, passes through the connecting rod 192 and the air outlet sleeve 191 and is discharged upward into the outside atmosphere. The airflow in the second air duct 10 passes through the connecting rod 192 and the air outlet sleeve 191 and is discharged upward into the outside atmosphere.

[0046] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
