[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] like Figure 1-4This is a schematic diagram of the structure of a tower heater proposed in this utility model. The tower heater of this utility model includes a base 1 and a tower body 2 disposed on the base. The tower body 2 includes a front tower body 3 and a rear tower body 4 fastened to the front tower body 3. An air outlet mesh cover 5 is detachably connected to the front tower body 3, and air inlets 6 are evenly distributed on the rear tower body 4. An air duct 18 is disposed inside the tower body 1 between the air inlets 6 and the air outlet mesh cover 5. A main motor mounting bracket 31 is disposed at the inlet of the air duct 18 extending to the air inlet 6. An exhaust motor 19 and exhaust blades 20 are installed inside the main motor mounting bracket 31. A PLC heating mesh plate 16 and an air guide grille 12 are disposed sequentially from the inside to the outside at the outlet of the air duct 18 extending to the air outlet mesh cover 5. Air guide blades 14 are disposed vertically on the air guide grille 12.

[0024] This embodiment combines tower fan and heating by incorporating an air duct, motor, and exhaust blades inside the tower body, and a PLC heating grid and air guide grille at the air duct outlet. Under the action of the motor, exhaust blades, air duct, PLC heating grid, and air guide grille, warm air is blown out from the air outlet cover, thus changing the traditional impeller rotation mechanism of the tower fan. At the same time, the air guide blades are used to adjust the direction of the warm air outlet, which is beneficial for controlling the direction of the air outlet.

[0025] In this embodiment, when the PLC heating grid plate 16 and the exhaust motor 19 are powered on, the exhaust motor 19 drives the exhaust blades 20 to work, so that the airflow enters the air duct 18 through the air inlet 6 and the air guide blades 14, and is blown out from the air duct outlet along the air duct. The airflow is heated by the PLC heating grid plate 16 at the air duct outlet to form hot air, and the hot air is blown out along the air guide grille 12 and the air outlet cover 5 to realize the heating function.

[0026] In a preferred embodiment, the air duct 18 includes a pair of parallel left and right side plates, an upper arc-shaped plate connecting the tops of the left and right side plates, and a lower arc-shaped plate connecting the lower parts of the left and right side plates. The gap between the upper and lower arc-shaped plates gradually increases from the air duct inlet to the air duct outlet. The end of the exhaust motor 19 away from the exhaust blades 20 extends into the air duct 18. In this embodiment, the air duct structure is conducive to expanding the air outlet area. At the same time, the built-in exhaust motor 19 structure makes the airflow blocked and diffused outward at the exhaust motor after entering the air duct, so that the exhaust motor plays the role of guiding the air. The outward diffused airflow is conducive to filling the entire air duct area and moving towards the air duct outlet, which facilitates the heating of the air at the outlet and the formation of hot airflow.

[0027] In a preferred embodiment, the PLC heating grid plate housing frame is configured as a square frame and is closedly connected to the air duct outlet. The air guide grille housing frame is configured as a square frame and is closedly connected to the air duct outlet. The end of the air guide grille housing frame extends out of the front tower body 3 near the air outlet cover 4. This structure in this embodiment is beneficial for forming a closed structure between the PLC heating grid plate housing frame and the air guide grille housing frame and the air duct outlet, so that hot air is blown directly out from the front tower body 3 and the air outlet cover 5, avoiding hot air from entering the electrical area inside the tower body 2.

[0028] In a preferred embodiment, an electrical compartment is located inside the tower body 2, above the air duct 18 and the PLC heating grid plate outer shell frame. A circuit board 15 is installed inside the electrical compartment. A switch knob 8 is located at the center of the top of the tower body 2. A thermostat 30, connected to the switch knob 8, is installed inside the electrical compartment. The thermostat 30 is electrically connected to the circuit board 15. In this embodiment, the circuit board 15 controls the operation of the PLC heating grid plate 16 and the exhaust motor 19. The switch knob 8 is used to start and stop the PLC heating grid plate 16 and the exhaust motor 19. Simultaneously, when the switch knob 8 is turned on, it controls the temperature. Through the thermostat 30 and the circuit board 15, the operating current of the PLC heating grid plate 16 is increased, thereby raising the temperature of the warm air outlet. A temperature sensor is installed at the lower part of the air duct 18 to monitor the temperature inside the air duct and feed it back to the circuit board, thus achieving the purpose of temperature control for the heater.

[0029] In a preferred embodiment, the top of the PLC heating grid plate extends out of the PLC heating grid plate housing frame and is provided with a wiring terminal 17 for connection to the circuit board 15. In this embodiment, this structure facilitates the electrical connection between the PLC heating grid plate and the circuit board 15. After the PLC heating grid plate and the circuit board 15 are connected, the front housing is fastened onto the rear housing.

[0030] In a preferred embodiment, the upper part of the tower body 2, at the connection between the front and rear tower bodies, is provided with an air guide operation slot and an air guide adjustment handle 7 that slides up and down within the air guide operation slot. Both ends of the air guide blades 14 are provided with air guide shafts that rotate on the air guide grille housing frame. One side of the air guide shaft extends out of the end side wall of the air guide grille housing frame and is connected to a connecting rod 13 for vertical movement. The top of the connecting rod 13 is connected to the air guide adjustment handle 7 through a connecting frame. In this embodiment, when the heater needs to be adjusted vertically, the air guide adjustment handle 7 can be manually adjusted to move up and down within the air guide operation slot, causing the connecting frame and the connecting rod 13 to move up and down together. When the connecting rod 13 moves up and down, the air guide shaft rotates on the air guide grille housing frame, thereby causing the air guide blades 14 to deflect and adjust their angle, achieving the purpose of vertical air guidance.

[0031] In a preferred embodiment, a guide slide 22 is provided at the base 1 extending into the tower body. A rotating seat 23, which rotates on the guide slide 22, is provided at the bottom of the housing. A central shaft 24, extending from the center of the guide slide 22 onto the upper surface of the rotating seat 23, is provided at the top of the rotating seat 23. A deflection motor mounting seat 28 is provided on the top of the rotating seat 23. A deflection motor 10 is mounted on the deflection motor mounting seat 28. The deflection motor 10 is connected to the central shaft 24 via a crankshaft 11 and a connecting piece 25. In this embodiment, when the deflection motor 10 is working, it drives the crankshaft 11, the connecting piece 25, and the central shaft 24 to rotate. When the central shaft 24 is limited and stationary, its reaction force drives the deflection motor 10, the crankshaft 11, and the connecting piece 25 to deflect along the central shaft 24. The motor 10 drives the deflection motor mounting seat 28, the rotating seat 23, and the housing to deflect and move on the guide slide 22, thereby realizing the deflection of the housing 2 along the center of the base 1, realizing the left and right air outlet of the heater, and increasing the air outlet range.

[0032] In a preferred embodiment, the rotating base 23 is provided with a pair of rear shell mounting brackets 9 that are fixedly connected to the rear tower body 4 by connecting bolts 27. The center of the front side wall of the rotating base 23 is provided with a snap-fit ​​groove 26 that is fixedly connected to the front tower body 3. In this embodiment, during installation, the rear tower body 4 is installed on the rotating base 23 by the rear shell mounting brackets 9. After the air duct and electrical components inside the shell are connected and installed in place, the side wall of the front tower body 3 is snapped onto the side wall of the rear tower body 4 to form a whole. At the same time, the bottom part of the front tower body 3 is snapped onto the snap-fit ​​groove 26 to realize the connection between the front tower body 3 and the rotating base 23. This connects the front tower body 3, the rear tower body 4, and the rotating base 23 into a whole to form a shell, making the shell structure firm and safe and reliable to use.

[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
