Description

Technical Field

[0001] This utility model belongs to the technical field of heating equipment, and in particular relates to an electric heater. Background Technology

[0002] An electric heater is a device that uses electrical energy to provide heat to a room. It converts electrical energy into heat energy through electric heating elements (such as heating wires, carbon fiber heating tubes, etc.), thereby increasing the air temperature and achieving a heating effect.

[0003] An existing electric heater, such as the one disclosed in application number CN2018217113617, includes a shell with an opening at the top. A heating device is located inside the shell, comprising a bracket mounted on the shell, an insulating rod with a heating wire wound around it, and the heating wire connected to a power source for heating. Multiple foot pedals are spaced apart inside the shell, positioned above the heating device. A ventilation hole is located at the bottom of the shell, below the heating device. Furthermore, the inner sidewall of the shell has opposing sliding grooves, with both ends of the foot pedals engaging with and movable within these grooves. Limiting components restrict the movement of each foot pedal.

[0004] In the aforementioned technical solution, the foot pedal is convenient for users to warm their feet, and its lateral movement facilitates the removal of foreign objects that may have fallen onto the heating device, resulting in a good user experience. However, in actual use, while the power of the heating device is adjustable, the height difference between the foot pedal and the heating device is fixed. If the heating device is set to a higher power, the foot pedal may become too hot, hindering the user's foot warming process. Therefore, there is room for improvement. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an electric heater that can flexibly adjust the height of the foot pedal to make it easier for users to warm their feet.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an electric heater, including a shell with an opening at the top and a heating mechanism disposed at the bottom of the shell, a cylinder that can slide up and down is disposed inside the shell, a plurality of detachable foot pedals are disposed inside the cylinder, and a lifting mechanism for driving the cylinder to move up and down is disposed on the outside of the shell.

[0007] Preferably, the upper end of the shell protrudes outward to form a first stop, and the upper end of the cylinder protrudes outward to form a second stop, with the second stop resting on the first stop.

[0008] Preferably, the lifting mechanism includes n cylinders, where n is an integer greater than or equal to 1. The first stop has n through holes, and each of the n through holes corresponds to one of the n cylinders. The cylinder body is fixedly mounted on the outer side of the housing, and the telescopic rod of the cylinder passes through the corresponding through hole and is connected to the lower end face of the second stop.

[0009] As a preferred choice, n can be 2, 3, or 4.

[0010] Preferably, a guide rod is fixedly provided on the lower end face of the second stop, and a guide hole is provided on the first stop, through which the guide rod passes.

[0011] Preferably, the inner wall of the cylinder is provided with a plurality of positioning mechanisms corresponding one-to-one with the foot pedal. The positioning mechanism includes two strip grooves that extend in the vertical direction. One end of the foot pedal abuts against the lower side of one of the strip grooves in the corresponding positioning mechanism, and the other end of the foot pedal abuts against the lower side of the other strip groove in the corresponding positioning mechanism.

[0012] Preferably, the upper end of the strip groove extends through the upper end face of the cylinder.

[0013] Preferably, a limiting post is fixedly provided on the lower side of the strip groove, and a limiting hole corresponding to the limiting post is provided on the foot pedal, with the limiting post inserted into the limiting hole.

[0014] Preferably, the heating mechanism includes a heating wire and a plurality of insulating rods, the insulating rods being spaced apart in a horizontal direction, and the heating wire being wound around the insulating rods.

[0015] Preferably, the lower end face of the housing is provided with a plurality of mounting ports, and a fan is provided in the mounting ports.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] 1. By setting up a cylinder and a lifting mechanism, the cylinder and the shell slide together vertically. The lifting mechanism is used to drive the cylinder to move up and down, thereby moving the foot pedal up and down, so as to adjust the height difference between the foot pedal and the heating mechanism. It has good flexibility and can prevent the foot pedal from getting too hot or too cold, and control the temperature of the foot pedal at a suitable temperature, so as to make it easy for users to warm their feet.

[0018] 2. The foot pedal height is adjustable, making it suitable for users of different heights and offering good usability;

[0019] 3. The foot pedal is detachably connected to the cylinder body, making it easy for users to remove the foot pedal and take out any foreign objects that have fallen onto the heating mechanism. This makes it more convenient to use. Of course, the air flow channel can also be enlarged by removing the foot pedal, which helps to improve the heat exchange efficiency.

[0028] Example 1: As Figures 1 to 3 As shown, an electric heater includes a housing 1 with an upper opening 11 and a heating mechanism 2 disposed at the bottom of the housing 1. A cylinder 3 that can slide up and down is disposed inside the housing 1. Multiple detachable foot pedals 4 are disposed inside the cylinder 3. A lifting mechanism 5 for driving the cylinder 3 to move up and down is disposed on the outside of the housing 1.

[0029] In this embodiment, the upper end of the shell 1 protrudes outward to form a first baffle 12, and the upper end of the cylinder 3 protrudes outward to form a second baffle 31, with the second baffle 31 resting on the first baffle 12.

[0030] In this embodiment, the heating mechanism 2 includes a heating wire 21 and a plurality of insulating rods 22. The insulating rods 22 are spaced apart in the horizontal direction, and the heating wire 21 is wound around the insulating rods 22.

[0031] In this embodiment, the lower end face of the housing 1 is provided with a plurality of mounting ports 13, and a fan 6 is provided in the mounting port 13. The fan 6 helps to quickly exhaust the hot air inside the housing 1, thereby improving the heat exchange efficiency. Conventionally, the fan 6 includes fan blades and a rotating motor, which will not be described in detail here.

[0032] Example 2: Figure 3 As shown, the rest is the same as in Embodiment 1, except that the lifting mechanism 5 includes n cylinders 51, where n is an integer greater than or equal to 1. The first stop 12 has n through holes 121, each corresponding to one of the n cylinders 51. The cylinder body of each cylinder 51 is fixedly mounted on the outer surface of the housing 1. The telescopic rod of each cylinder 51 passes through the corresponding through hole 121 and connects to the lower end face of the second stop 31. Preferably, n is 2, 3, or 4. The cylinder 51 pushes the cylinder 3 with the second stop 31 to move up and down, resulting in good stability.

[0033] In this embodiment, a guide rod 32 is fixedly provided on the lower end face of the second stop 31, and a guide hole 122 is provided on the first stop 12. The guide rod 32 passes through the guide hole 122, and the guide rod 32 and the guide hole 122 cooperate to play a guiding role, which helps to improve the stability of the structure.

[0034] Example 3: Figures 3 to 5 As shown, the rest of the parts are the same as in Embodiment 1. The difference is that the inner wall of the cylinder 3 is provided with a plurality of positioning mechanisms 33 corresponding to the foot pedal 4. The positioning mechanism 33 includes two strip grooves 331, which extend in the vertical direction. One end of the foot pedal 4 abuts against the lower side of one strip groove 331 in the corresponding positioning mechanism 33, and the other end of the foot pedal 4 abuts against the lower side of the other strip groove 331 in the corresponding positioning mechanism 33.

[0035] In this embodiment, the upper end of the strip groove 331 penetrates the upper end face of the cylinder 3, which facilitates the processing of the cylinder 3 and the installation of the foot pedal 4.

[0036] In this embodiment, a limiting post 332 is fixedly provided on the lower side of the strip groove 331, and a limiting hole 41 corresponding to the limiting post 332 is provided on the foot pedal 4. The limiting post 332 is inserted into the limiting hole 41, which helps to improve the stability of the connection and avoids the risk of the foot pedal 4 detaching from the strip groove 331 during use, thus improving safety. Furthermore, the upper end of the limiting post 332 is provided with a beveled guide surface to facilitate quick assembly with the foot pedal 4.
