DETAILED DESCRIPTION

[0022] Specific embodiment one: please refer to Figures 1-5An adjustable three-outlet heater includes a base 1, a top shell 2, a control element 3, a first fan 4, and a second fan 5. The base 1 and the top shell 2 are detachably connected by a snap-fit ​​mechanism. The base 1 has an exhaust port 11 on its side for ventilation of the heater. The top shell 2 has an air inlet 21 and an air inlet 22, which correspond to the first fan 4 and the second fan 5, respectively. The control element 3 is detachably installed inside the base 1 and electrically connected to the first fan 4 and the second fan 5, respectively, for controlling the operation of the first fan 4 and the second fan 5.

[0023] The top shell 2 has three hot air outlets 23 on both sides and in the middle. A heating device 6 is installed in the hot air outlet 23 to heat the air drawn in by the first fan 4 and the second fan 5 through the air inlet 21 and the air inlet 22, thereby improving the heating efficiency of the heater.

[0024] like Figure 2 The base 1 shown has an internal airflow channel 7. The first fan 4 is connected to the exhaust port 11 and the heating device 6 corresponding to the hot air outlet 23 near the exhaust port 11 through the airflow channel 7. The second fan 5 is connected to the heating devices 6 corresponding to the other two hot air outlets 23 through the airflow channel 7. The heating part corresponding to the first fan 4 can be used for ventilation and outputting hot air. The heating part corresponding to the second fan 5 increases the efficiency of outputting hot air by increasing the number of hot air outlets 23. At this time, if only the first fan 4 is turned on by the control element 3, it is a single hot air outlet 23 operation. If only the second fan 5 is turned on by the control element 3, it is a double hot air outlet operation. If both the first fan 4 and the second fan 5 are turned on by the control element 3, it is a triple hot air outlet operation. The switching of the three levels improves the flexibility of the heater. At the same time, it can meet different heating needs, ensuring the efficiency of the heater and making the heater more energy-efficient.

[0025] Specifically, such as Figure 3 The flow channel 7 shown includes a first flow channel 71 and a second flow channel 72. The first flow channel 71 includes a folded plate 711, a first arc plate 712 and a first support plate 713 connected in sequence to form a semi-closed flow channel. The first fan 4 drives air to flow along the first flow channel 71 to the exhaust port 11 and the hot air outlet 23 near the first fan 4 for heat generation and air exchange with the outside. The second flow channel 72 includes a pair of second arc plates 721 and a pair of second support plates 722 connected symmetrically with respect to the center of the second fan 5 to form a closed flow channel symmetrical about the center of the second fan 5. The second fan 5 drives air to flow along the second flow channel 72 to the hot air outlets 23 on both sides of the second fan 5 for uniform heating of the air drawn in by the second fan 5, avoiding local overheating, thereby improving the heating effect.

[0026] Specifically, such as Figure 4The heating device 6 includes a cover plate 61, a heating part 62, a pair of connecting plates 63, and a terminal 64. The cover plate 61 is detachably connected to the pair of connecting plates 63 at both ends, and the connecting plates 63 are detachably installed on the upper part of the flow guide channel 7. The heating part 62 is clamped between the cover plate 61 and the connecting plate 63, and the terminal 64 is arranged on the side of the cover plate 61 and used to electrically connect the heating device 6 with the control element 3. A plurality of grids are opened on the top of the cover plate 61 to ensure that the hot air heated by the heating part 62 can smoothly flow to the hot air outlet 23, and at the same time, the user can be prevented from directly contacting the heating part 62 to reduce the risk of scalding.

[0027] Specifically, the heating device 6 is detachably installed on the first support plate 713 and the pair of second support plates 722 to heat the air sucked by the first fan 4 and the second fan 5.

[0028] Specifically, a plurality of support columns 12 are further arranged inside the base 1, and the support columns 12 are detachably connected with the heating device 6 to fix the heating device 6 and make the heating device 6 away from the bottom of the base 1, thereby avoiding that the heating device 6 causes the local overheating of the base 1 and damages the structure of the base 1.

[0029] Specifically, as shown in the drawings, Figure 5 The side of the cover plate 61 is provided with an extension part 65, one end of the extension part 65 abuts against the folding plate 711 of the flow guide channel 7, and the profile of the extension part is wide at the top and narrow at the bottom, which reduces the gap between the heating device 6 and the first fan 4 and the second fan 5, and avoids the hot air escaping to the upper part of the flow guide channel along the gap to waste heat.

[0030] In use, the first fan 4 or the second fan 5 or both of them are turned on by the control element 3 according to the user's own needs to realize the switching of the single hot air outlet 23 or the double hot air outlet 23 or the triple hot air outlet 23, so as to meet different heating needs, ensure the efficiency of the warmer, and achieve the energy-saving effect. The first fan 4 sucks the air from the air inlet 21, transports the air to the heating device 6 through the first flow guide groove 71, heats the air, and outputs the hot air at the hot air outlet 23, and at the same time, the air in the first flow guide groove 71 is discharged to the outside through the air outlet 11 to realize the air exchange function. The second fan 5 sucks the air from the air inlet 22, transports the air to the heating device 6 through the second flow guide groove 72, heats the air, and outputs the hot air at the hot air outlet 23, and through the pair of heating devices 6 symmetrically arranged about the second fan 5, the heating efficiency is improved. At the same time, the hot air is blocked by the extension part 65, which reduces the escape of the hot air to the upper part of the flow guide channel 7 along the gap, thereby avoiding the waste of heat.

[0031] The above merely describes a preferred embodiment of the present application; the scope of protection of the present application is not limited thereto. Any skilled person in the art, according to the technical scheme and improvement concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the scope of protection of the present application.
