Description

Technical Field

[0001] This invention relates to the field of radiant heater technology, specifically a mobile radiant space heater. Background Technology

[0002] With increasing demand for instant heating in localized spaces, energy conservation, environmental protection, and flexibility, portable heaters have become an important heating solution for homes, garages, workshops, warehouses, outdoor commercial areas, and temporary locations. However, they generally suffer from low thermal inertia (cooling down immediately upon shutdown), extremely high surface temperatures posing safety hazards, potentially glaring infrared wavelengths, and relatively low energy efficiency. Some low-end products lack effective overheat protection and tip-over power-off functions. As an improvement on electric heating tubes, their infrared radiation spectrum is softer, and thermal efficiency is slightly improved, but there has been no fundamental change in portability, safety protection, and overall energy efficiency. They typically use propane as fuel, generating flameless infrared thermal radiation through catalytic combustion. They have high power and are particularly suitable for outdoor or well-ventilated semi-outdoor spaces. However, they must be connected to a fuel tank, pose combustion exhaust emissions (requiring ventilation), and carry safety risks associated with open flames or high-temperature catalytic plates. They also do not conform to the convenient concept of "pure electric" portability. They use heating wires to heat dense metal or ceramic plates, causing them to emit softer and more comfortable mid- and far-infrared rays. While the surface temperature is relatively low and safety is improved, it generally suffers from drawbacks such as slow preheating, large size and weight, limited power density, and high cost.

[0003] According to the radiative space electric heater structure proposed by patent number CN223274233U, the moving direction and moving speed of the electric heater structure can be controlled and adjusted by controlling and adjusting the rotation direction and speed of the output shaft of the forward and reverse geared motor, which solves the technical problem of inconvenient and labor-saving movement. However, this device prioritizes irradiation methods for specific positions, and the heating efficiency is low when changing the irradiation position by moving the entire device. Summary of the Invention

[0004] To solve the above technical problems, the present invention is achieved through the following technical solution: a mobile radiant space heater, comprising a fixed base, a support frame fixedly connected to the bottom of the fixed base, an adjusting screw threadedly connected to the top of the fixed base, a rotating frame engaged with the side of the adjusting screw, a heating coil rotatably connected to the top of the inner wall of the rotating frame, a fixed base plate fixedly connected to the bottom of the heating coil, a reflector plate rotatably connected to the top of the fixed base plate at a position on one side of the heating coil, a cleaning device fixedly connected to the bottom of the fixed base plate, the bottom of the cleaning device rotatably connected to the bottom of the inner wall of the rotating frame, and the rotating frame rotatably connected to the top of the fixed base via a bracket;

[0005] The heating coil includes a rotating shaft. A limiting strip is rotatably connected to the top of the rotating shaft, and a spring is fixedly connected to the side of the limiting strip. A conical top is fixedly connected to the bottom of the rotating shaft, and a fixed frame is fixedly connected to the bottom of the conical top. A spiral heating coil is fixedly connected to the bottom of the inner wall of the fixed frame. The bottom of the spiral heating coil is fixedly connected to the top of a fixed base plate. A rotating frame is sleeved on the side of the rotating shaft and rotatably connected to it. When the spiral heating coil is activated, it heats and generates infrared radiation, which is emitted and reflected along the side of a reflector, thereby heating surrounding objects. Rotating the reflector causes it to reflect the infrared radiation generated by the spiral heating coil in a directional manner. The fixed frame secures the spiral heating coil. The conical top design reduces the probability of dust and other impurities falling directly onto the surface of the spiral heating coil. The cooperation between the rotating shaft and the rotating frame facilitates the rotation of the spiral heating coil under the action of the fixed base plate. This allows for adjustment of the reflector angle and, by adjusting the position of the fixed base plate, directional heating of specific locations. The limiting strip and spring clips ensure that the coil remains at a fixed angle after adjustment, facilitating prolonged directional heating of specific locations. After adjustment, rotating the adjusting screw causes the rotating frame to rotate along the top of the fixed base, allowing for adjustment of the vertical angle of the rotating frame and further targeted irradiation and heating of specific locations.

[0006] Preferably, the reflector includes a reflective rotating plate, a light-concentrating groove is fixedly connected to the side of the reflective rotating plate, a forked bracket is fixedly connected to the top of the reflective rotating plate, a rotating handle is fixedly connected to the top of the forked bracket, and a fixing component is fixedly connected to the bottom of the reflective rotating plate. The fixing component passes through the top of the fixing base plate and is rotatably connected to the top of the fixing base plate.

[0007] Preferably, the fixing assembly includes a rotating shaft with a threaded groove on its side and a positioning groove on the inner wall of the threaded groove. A limit ring is fitted and rotatably connected to the side of the rotating shaft. A spring is fixedly connected to the top of the limit ring, and a support groove is fixedly connected to the top of the spring. A ball bearing is rotatably connected to the inner wall of the support groove. The rotating shaft passes through the bottom of the fixed base plate and is rotatably connected to the bottom of the fixed base plate. The top of the ball bearing contacts the bottom of the fixed base plate. The top of the rotating shaft is fixedly connected to the bottom of the reflective rotating plate. When adjusting the irradiation angle, rotating the handle causes the forked bracket to rotate, which in turn causes the reflective rotating plate to rotate, which in turn causes the rotating shaft to rotate. The rotating shaft drives the limiting ring to rotate. The limiting ring is fixed to the side of the rotating shaft through the positioning groove, thus supporting the bottom of the spring. The top of the spring provides elastic support to the bottom of the support groove, which in turn provides elastic support to the ball bearings. The ball bearings contact the bottom of the fixed base plate, thereby fixing the rotation angle of the rotating shaft through the contact friction of the ball bearings while the rotating shaft rotates. This makes it easier for the rotating shaft to remain in a fixed position after adjustment. The limiting ring slides along the threaded groove to adjust the elastic distance of the spring, thereby changing the damping of the rotating reflector plate. This makes it easier to maintain a fixed position at different reflection angles. The focusing groove facilitates the guidance and reflection of the infrared rays generated by the spiral heating coil, thereby improving the heating accuracy.

[0008] Preferably, the cleaning device includes an air guide pipe with an air inlet on its side. A pneumatic fan blade is rotatably connected to the inner wall of the air guide pipe. A filter ring is fixedly connected to the inner wall of the air guide pipe above the pneumatic fan blade. An air guide hole is connected to the top of the air guide pipe. A spiral jet hole is provided on the side of the air guide hole. The top of the air guide pipe is fixedly connected to the bottom of the fixed base plate. The air guide hole extends into the center of the spiral heating coil and is fixedly connected to the top of the inner wall of the fixed frame.

[0009] Preferably, the pneumatic fan blade includes a rotating base, a downward pressing fan blade is fixedly connected to the side of the rotating base, an arc-shaped blade is fixedly connected to the top of the downward pressing fan blade, the rotating base is fixedly connected to the top of the arc-shaped blade, and the bottom of the rotating base is rotatably connected to the inner wall of the air guide pipe through a bracket.

[0010] Preferably, the filter ring includes a fixed ring, with a conical air outlet pipe connected to the top center of the fixed ring. A concave filter ring is fitted and rotatably connected to the side of the conical air outlet pipe. The side of the fixed ring is fixedly connected to the inner wall of the air guide pipe. The fixed ring is positioned at the top of the downward-pressing fan blade, and the conical air outlet pipe is positioned above the air guide fan blade. When the rotating base is activated, the rotating base rotates, causing the downward-pressing fan blade to rotate. The rotation of the downward-pressing fan blade causes air to descend along the top of the fixed ring. The air enters the top of the concave filter ring along the inner wall of the air inlet, is filtered by the concave filter ring, passes through the bottom of the fixed ring, and reaches the bottom of the downward-pressing fan blade. The air then flows along the downward-pressing fan blade... The air flows along the side of the air duct and enters the side of the air guide fan blades along the arc-shaped blades. It then rises along the inner wall of the conical air outlet and enters the interior of the air guide hole. The air is filtered and guided, then dispersed and ejected along the spiral jet hole. The air is ejected through the gap between the spiral heating coils, which facilitates the ejection of filtered air along the gap between the spiral heating coils, thereby reducing the probability of dust and other impurities falling on the surface of the spiral heating coils. Furthermore, the position of the air inlet on the side of the air guide pipe reduces the possibility of dust entering along the bottom of the air guide pipe. The filtration effect and internal concavity of the concave filter ring facilitate the collection of dust and other impurities inside the concave filter ring.

[0011] Preferably, the rotating frame includes a rotating frame, a rotating gear is fixedly connected to one side of the bottom of the rotating frame, the side of the rotating gear is rotatably connected to the top of the fixed base via a bracket, a limiting ring adapted to the limiting strip is fixedly connected to the top of the rotating frame, the side of the rotating gear meshes with the side of the adjusting screw, the bottom of the inner wall of the rotating frame is rotatably connected to the top of the air guide pipe via a rotating shaft, and the top of the rotating frame, located below the limiting ring, is sleeved on the side of the rotating shaft and rotatably connected to the rotating shaft. The rotation of the adjusting screw drives the rotating gear to rotate, and the rotation of the rotating gear is connected to the fixed base via the bracket. The top of the device rotates, and the rotating gear rotates along the top of the fixed base. The rotation of the rotating gear drives the rotating frame to rotate, which in turn moves the limiting ring. Thus, the rotation of the rotating gear drives the rotating frame to move the spiral heating coil and the air guide tube synchronously, thereby changing the vertical irradiation angle of the spiral heating coil. The limiting strip engages with the inner wall of the limiting ring through the elastic drive of the spring, thereby preventing the rotating shaft from rotating back. The adjusting screw is linked with the rotating gear to facilitate the synchronous rotation of multiple sets of rotating gears, which in turn facilitates the synchronous adjustment of multiple sets of spiral heating coils, thus facilitating directional irradiation of specific positions.

[0012] This invention provides a mobile radiant space heater. It has the following advantages:

[0013] 1. This mobile radiant space heater is equipped with a spiral heating coil. Upon activation, the coil heats up, generating infrared radiation that is emitted outwards. The infrared radiation is reflected by the side of a reflector, thus heating surrounding objects. By rotating the reflector, the infrared radiation generated by the spiral heating coil can be directionally reflected for concentrated heating of specific areas. A fixed frame stabilizes the spiral heating coil, and the conical top design effectively reduces the probability of dust and other impurities falling directly onto the coil surface. The rotating shaft and rotating frame work together to allow the spiral heating coil to rotate under the influence of the fixed base plate. This allows for directional heating of specific locations by adjusting the reflector angle and utilizing the positional changes of the fixed base plate. The combination of a limiting strip and a spring ensures the device maintains a fixed angle after adjustment, facilitating prolonged directional heating of the target location. After horizontal adjustment, the adjusting screw can be further rotated, causing the rotating frame to rotate along the top of the fixed base, thereby adjusting the vertical angle of the rotating frame for more precise irradiation and heating of specific locations.

[0014] 2. This portable radiant space heater is equipped with a rotating handle. When adjusting the irradiation angle, rotating the handle drives the forked bracket to rotate, which in turn drives the reflective rotating plate to rotate. The reflective rotating plate is connected via a rotating shaft, which rotates synchronously with a limiting ring. The limiting ring is fixed to the side of the rotating shaft via a positioning groove and provides support to the bottom of the spring. The top of the spring elastically supports the bottom of the support groove, which in turn provides elastic support to the ball bearings, keeping them in contact with the bottom of the fixed base plate. During the rotation of the rotating shaft, the ball bearings help fix the rotation angle of the rotating shaft through contact friction, thus stabilizing the adjusted position. Simultaneously, the limiting ring can slide spirally along the threaded groove to adjust the elastic distance of the spring, thereby changing the damping force of the reflective rotating plate during rotation and achieving stable maintenance of the desired position at different reflection angles. The focusing groove helps guide and reflect the infrared rays generated by the spiral heating coil, thereby improving the heating accuracy and efficiency.

[0015] 3. This mobile radiant space heater is equipped with a rotating base. When the base rotates, it drives the downward-pressing fan blades, causing air to flow downwards along the top of the fixed ring. The air enters the top of the concave filter ring through the air inlet, is filtered, and then passes through the bottom of the fixed ring to reach below the downward-pressing fan blades. Subsequently, the airflow flows along the side of the downward-pressing fan blades, guided by the curved blades, and enters the side of the air guide fan blades, rising along the inner wall of the conical air outlet pipe into the air guide hole. Finally, the filtered air is dispersed and ejected through the spiral jet holes, passing through the gaps between the spiral heating coils. This process not only effectively reduces the probability of dust and impurities adhering to the coil surface, but also reduces the possibility of dust entering from the bottom of the air guide pipe because the air inlet is located on the side of the air guide pipe. The concave filter ring, through its filtering action and internal recessed structure, can collect dust and impurities inside the recesses, facilitating subsequent cleaning.

[0016] 4. This mobile radiant space heater is equipped with a rotating gear. When the adjusting screw rotates, it drives the rotating gear to rotate. The rotating gear is connected to the top of the fixed base via a bracket and rotates accordingly. The rotation of the rotating gear drives the rotating frame to move, which in turn moves the limiting ring, allowing the rotating frame to synchronously adjust the position of the spiral heating coil and the air guide pipe, thereby changing the vertical irradiation angle of the spiral heating coil. The limiting strip engages with the inner wall of the limiting ring using the elasticity of a spring, ensuring that the rotating shaft does not easily rotate back and maintaining angle stability. The linkage design between the adjusting screw and the rotating gear supports the synchronous rotation of multiple sets of rotating gears, thus achieving synchronous adjustment of multiple sets of spiral heating coils, facilitating uniform and precise directional irradiation of specific locations.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] For the first embodiment, please refer to... Figures 1-8 The present invention provides a technical solution: a mobile radiant space heater, comprising a fixed base 1, a support frame 2 fixedly connected to the bottom of the fixed base 1, an adjusting screw 3 threadedly connected to the top of the fixed base 1, a rotating frame 4 engaged on the side of the adjusting screw 3, a heating coil 6 rotatably connected to the top of the inner wall of the rotating frame 4, a fixed base plate 5 fixedly connected to the bottom of the heating coil 6, a reflector 7 rotatably connected to the top of the fixed base plate 5 at a position on one side of the heating coil 6, a cleaning device 8 fixedly connected to the bottom of the fixed base plate 5, the bottom of the cleaning device 8 rotatably connected to the bottom of the inner wall of the rotating frame 4, and the rotating frame 4 rotatably connected to the top of the fixed base 1 via a bracket;

[0028] The heating coil 6 includes a rotating shaft 601. The top of the rotating shaft 601 is rotatably connected to a limiting strip 602. A spring piece 603 is fixedly connected to the side of the limiting strip 602. A conical top 604 is fixedly connected to the bottom of the rotating shaft 601. A fixed frame 605 is fixedly connected to the bottom of the conical top 604. A spiral heating coil 606 is fixedly connected to the bottom of the inner wall of the fixed frame 605. The bottom of the spiral heating coil 606 is fixedly connected to the top of the fixed base plate 5. A rotating frame 4 is sleeved on the side of the rotating shaft 601 and rotatably connected to the rotating shaft 601.

[0029] The rotating frame 4 includes a rotating frame 401. A rotating gear 402 is fixedly connected to one side of the bottom of the rotating frame 401. The side of the rotating gear 402 is rotatably connected to the top of the fixed base 1 through a bracket. A limiting ring 403 adapted to the limiting strip 602 is fixedly connected to the top of the rotating frame 401. The side of the rotating gear 402 meshes with the side of the adjusting screw 3. The bottom of the inner wall of the rotating frame 401 is rotatably connected to the top of the air guide pipe 801 through a rotating shaft. The top of the rotating frame 401 is sleeved on the side of the rotating shaft 601 and rotatably connected to the rotating shaft 601 at a position below the limiting ring 403.

[0030] The spiral heating coil 606 is activated, generating infrared radiation that is emitted. This infrared radiation directly strikes the surface of the reflector 7 and is reflected along its side. The radiation is absorbed by surrounding objects, thus heating them. The reflector 7 is manually rotated according to the actual heating position, reflecting the infrared radiation generated by the spiral heating coil 606. Multiple sets of reflectors 7 are combined for easy adjustment and directional reflection. The fixed frame 605 secures the spiral heating coil 606. The conical top 604 reduces the probability of dust and other impurities falling directly onto the surface of the spiral heating coil 606. The cooperation between the rotating shaft 601 and the rotating frame 4 ensures the overall stability of the spiral heating coil 606. The base plate 5 rotates under its driving force, which facilitates the adjustment of the angle of the reflector plate 7. After the position of the base plate 5 is adjusted, the specific position is directionally heated. The setting of the limiting strip 602 and the spring piece 603 facilitates the reset of the limiting strip 602 under the elastic force of the spring piece 603, so that the limiting strip 602 is engaged with the inner wall of the limiting ring 403 to brake. After adjustment, it is held at a fixed angle, which facilitates long-term directional heating of the specific position after adjustment. After adjustment, the adjusting screw 3 is rotated, and the adjusting screw 3 drives the rotating frame 401 to rotate along the top of the fixed base 1, which facilitates the adjustment of the vertical angle of the rotating frame 401, so as to further irradiate and heat the specific position. The rotation of the adjusting screw 3 drives the rotating gear 402 to rotate. The rotating gear 402 rotates through the bracket and the top of the fixed base 1. The rotating gear 402 rotates along the top of the fixed base 1, which drives the rotating frame 401 to rotate and moves the limiting ring 403. Thus, the rotation of the rotating gear 402 drives the rotating frame 401 to move the spiral heating coil 606 and the air guide tube 801 synchronously, thereby changing the vertical irradiation angle of the spiral heating coil 606. The limiting strip 602 engages with the inner wall of the limiting ring 403 through the elastic drive of the spring 603, thereby preventing the rotating shaft 601 from rotating back. The linkage between the adjusting screw 3 and the rotating gear 402 facilitates the synchronous rotation of multiple sets of rotating gears 402, thereby facilitating the synchronous adjustment of multiple sets of spiral heating coils 606 and enabling directional irradiation of specific positions.

[0031] For the second embodiment, please refer to... Figures 1-4 Based on the first embodiment, the present invention provides a technical solution: the reflector 7 includes a reflective rotating plate 701, a light-concentrating groove 702 is fixedly connected to the side of the reflective rotating plate 701, a forked bracket 703 is fixedly connected to the top of the reflective rotating plate 701, a rotating handle 704 is fixedly connected to the top of the forked bracket 703, and a fixing component 705 is fixedly connected to the bottom of the reflective rotating plate 701. The fixing component 705 passes through the top of the fixing base plate 5 and is rotatably connected to the top of the fixing base plate 5.

[0032] The fixing assembly 705 includes a rotating shaft 7051. A threaded groove 7052 is provided on the side of the rotating shaft 7051. A positioning groove 7053 is provided on the inner wall side of the threaded groove 7052. A limiting ring 7054 is sleeved and rotatably connected to the side of the rotating shaft 7051. A spring 7055 is fixedly connected to the top of the limiting ring 7054. A support groove 7056 is fixedly connected to the top of the spring 7055. A ball bearing 7057 is rotatably connected to the inner wall of the support groove 7056. The rotating shaft 7051 passes through the bottom of the fixing base plate 5 and is rotatably connected to the bottom of the fixing base plate 5. The top of the ball bearing 7057 contacts the bottom of the fixing base plate 5. The top of the rotating shaft 7051 is fixedly connected to the bottom of the reflective rotating plate 701.

[0033] When adjusting the illumination angle, rotating the handle 704 causes the forked bracket 703 to rotate, which in turn rotates the reflector plate 701. The reflector plate 701 then rotates the rotating shaft 7051, which in turn rotates the limiting ring 7054. The limiting ring 7054 is fixed to the side of the rotating shaft 7051 via the positioning groove 7053, thus supporting the bottom of the spring 7055. The top of the spring 7055 provides elastic support to the bottom of the support groove 7056, which in turn provides elastic support to the ball bearing 7057. 057 contacts the bottom of the fixed base plate 5, thereby fixing the rotation angle of the rotating shaft 7051 through the contact friction of the ball 7057 while the rotating shaft 7051 rotates. This makes it easy for the rotating shaft 7051 to remain fixed in a fixed position after adjustment. The elastic distance of the spring 7055 is adjusted by the limit ring 7054 sliding along the threaded groove 7052, thereby changing the damping of the rotating reflector plate 701 when it rotates. This makes it easy to maintain a fixed position at different reflection angles. The setting of the focusing groove 702 facilitates the guidance and reflection of the infrared rays generated by the spiral heating coil 606, thereby improving the heating accuracy.

[0034] Third embodiment, please refer to Figures 1-7 Based on the second embodiment, the present invention provides a technical solution: the cleaning device 8 includes an air guide pipe 801, an air inlet 802 is provided on the side of the air guide pipe 801, a pneumatic fan blade 803 is rotatably connected to the inner wall of the air guide pipe 801, a filter ring 804 is fixedly connected to the inner wall of the air guide pipe 801 above the pneumatic fan blade 803, an air guide hole 805 is connected to the top of the air guide pipe 801, a spiral jet hole 806 is provided on the side of the air guide hole 805, the top of the air guide pipe 801 is fixedly connected to the bottom of the fixed base plate 5, and the air guide hole 805 extends into the inner center of the spiral heating coil 606 and is fixedly connected to the top of the inner wall of the fixed frame 605.

[0035] The pneumatic fan blade 803 includes a rotating base 8031, a downward pressing fan blade 8032 fixedly connected to the side of the rotating base 8031, an arc-shaped blade 8033 fixedly connected to the top of the downward pressing fan blade 8032, a rotating base 8031 ​​fixedly connected to the top of the arc-shaped blade 8033, and the bottom of the rotating base 8031 ​​is rotatably connected to the inner wall of the air guide pipe 801 through a bracket.

[0036] The filter ring 804 includes a fixing ring 8041, with a conical air outlet pipe 8042 connected to the top center of the fixing ring 8041. A concave filter ring 8043 is sleeved and rotatably connected to the side of the conical air outlet pipe 8042. The side of the fixing ring 8041 is fixedly connected to the inner wall side of the air guide pipe 801. The fixing ring 8041 is located at the top of the downward pressure fan blade 8032, and the conical air outlet pipe 8042 is located above the air guide fan blade 8034.

[0037] The rotating base 8031 ​​is activated, and its rotation drives the downward-pressing fan blade 8032 to rotate. The rotation of the downward-pressing fan blade 8032 causes air to descend along the top of the fixed ring 8041. The air enters the top of the concave filter ring 8043 along the inner wall of the air inlet 802, is filtered by the concave filter ring 8043, passes through the bottom of the fixed ring 8041, and reaches the bottom of the downward-pressing fan blade 8032. The air flows along the side of the downward-pressing fan blade 8032 and, guided by the arc-shaped blade 8033, enters the side of the air guide fan blade 8034. It then rises along the inner wall of the conical air outlet pipe 8042 and enters the air guide hole. Inside 805, air is dispersed and ejected through the spiral jet hole 806 after being filtered and guided. The air is ejected through the gap between the spiral heating coils 606, which facilitates the ejection of filtered air through the gap between the spiral heating coils 606, thereby reducing the probability of dust and impurities falling on the surface of the spiral heating coils 606. Furthermore, the air inlet 802 is located on the side of the air guide pipe 801, which reduces the possibility of dust entering through the bottom of the air guide pipe 801. Through the filtering effect and internal concavity of the concave filter ring 8043, dust and impurities are easily collected inside the concave recess of the concave filter ring 8043.

[0038] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
