[0033] Please refer to Figures 1 to 13 The embodiment of the present application provides an electric heater 10, which comprises an electric heater body 100, a handle piece 200 and a heat insulation sleeve 300. The electric heater body 100 is provided with a containing space 101. The handle piece 200 comprises a connecting part 210 and a handle part 220 connected with each other. The connecting part 210 is rotatably connected to the electric heater body 100. The heat insulation sleeve 300 is sleeved on the outer periphery of the handle part 220. The handle piece 200 can be selectively in a storage state and an unfolded state. When the handle piece 200 is in the storage state (as shown in the figure), the handle piece 200 is embedded in the containing space 101. When the handle piece 200 is in the unfolded state (as shown in the figure), the handle part 220 is arranged opposite to and spaced from the electric heater body 100. Figure 3 The handle part 220 is arranged opposite to and spaced from the electric heater body 100. Figure 1

[0034] In this way, the handle piece 200 can be embedded in the containing space 101 of the electric heater body 100 when not in use, so as to reduce the space occupied by the equipment during carrying or storage, and enable the user to more conveniently manage the electric appliance in a limited space.

[0035] In addition, the handle piece 200 can be converted from the storage state to the unfolded state, so as to provide a simple and stable hand-holding point, and enable the user to more easily move the electric heater 10, thereby improving the convenience of use.

[0036] In addition, the design of the heat insulation sleeve 300 effectively prevents the heat generated by the electric heater 10 from being transmitted to the handle part 220, so as to prevent the user from being scalded by touching the high-temperature surface during carrying, thereby improving the safety of use.

[0037] In some embodiments, the containing space 101 and the handle piece 200 are both located at the top of the electric heater body 100.

[0038] In this way, the handle piece 200 is arranged at the top of the electric heater 10, so as to make the user more in line with the ergonomic principle when lifting the electric heater 10, reduce the action of bending over or tilting the body, and reduce the physical consumption and the risk of injury during carrying.

[0039] ​In addition, since the handle 200 and the accommodation space 101 are both on the same horizontal plane (i.e., the top), this helps to maintain the consistency and simplicity of the appearance of the electric heater 10, improving the visual aesthetics of the product.

[0040] Moreover, arranging the handle 200 on the top can avoid interference with other components of the electric heater 10 (such as the heating element, control panel, etc.), simplifying the internal structure design, and facilitating production and assembly.

[0041] In some embodiments, the accommodation space 101 can be located at the edge of the mounting frame 110; alternatively, the accommodation space 101 can be arranged as a groove that fits the handle 200 and the heat insulation sleeve 300.

[0042] In some embodiments, the electric heater body 100 includes a mounting frame 110 and a limiting ring 120, the connecting portion 210 is provided with a connecting column 211, the connecting column 211 is rotatably arranged in the mounting frame 110, the limiting ring 120 is arranged at the end of the connecting column 211 away from the connecting portion 210, and the connecting portion 210 and the limiting ring 120 are located on opposite sides of the mounting frame 110.

[0043] In this way, the rotatable connection between the connecting column 211 and the mounting frame 110 and the design of the limiting ring 120 ensure the stability of the handle 200 in the unfolded state. This structure can effectively prevent the handle 200 from accidentally loosening or falling off during transportation, improving the reliability of the product.

[0044] In addition, the combined design of the connecting column 211 and the limiting ring 120 makes the installation of the handle 200 more intuitive and simple, reducing the complexity of production and assembly, improving production efficiency, and facilitating user self-maintenance or replacement of parts.

[0045] Moreover, the rotatable connection design combined with the limiting ring 120 fixation not only provides a smooth operation experience, but also ensures that the handle 200 can be accurately placed in the required storage or unfolded position each time, enhancing user satisfaction.

[0046] In some embodiments, the connecting portion 210 and the electric heater body 100 can be connected by a bearing.

[0047] In some embodiments, the accommodation space 101 can be located at the edge of the mounting frame 110. The handle 200 can be arranged in a generally U-shaped manner. When the handle 200 is in the storage state, the handle 200 can be tightly attached to the edge of the mounting frame 110.

[0048] In some embodiments, the connecting column 211 is provided with a mounting groove 212, and the limiting ring 120 is embedded in the mounting groove 212 and arranged around the circumference of the connecting column 211. In this way, the design of the mounting groove 212 and the embedded circumferential arrangement of the limiting ring 120 can make the limiting ring 120 more accurately positioned on the connecting column 211, reduce the positional error during assembly, and improve the consistency and accuracy of assembly.

[0049] The mounting groove 212 is arranged at the end of the connecting column 211 and is in the shape of an annular groove. The depth and width of the mounting groove 212 should match those of the limiting ring 120 to ensure that the limiting ring 120 can be stably embedded therein and arranged around the connecting column 211. The mounting groove 212 can have a slight guide slope or guide groove inside to facilitate the installation of the limiting ring 120.

[0050] The limiting ring 120 is made of a flexible material (such as spring steel or nylon) and has a certain flexibility and restoring force, so that it can rotate freely in the mounting groove 212 but will not easily slide out. The limiting ring 120 is generally arranged in the shape of a ring.

[0051] In some embodiments, the limiting ring 120 is provided with a notch 121 on the side of the limiting ring 120 facing the connecting column 211. In this way, the notch 121 provides a space for elastic deformation of the limiting ring 120, which facilitates the installation of the limiting ring 120 in the mounting groove 212.

[0052] In some embodiments, the mounting frame 110 includes a connecting plate 111, a first side plate 112, and a second side plate 113. The connecting plate 111 is connected between the first side plate 112 and the second side plate 113. The first side plate 112 and the second side plate 113 are arranged opposite to and spaced apart from each other. The connecting column 211 is rotatably connected to the first side plate 112. The connecting portion 210 and the limiting ring 120 are located on opposite sides of the first side plate 112.

[0053] In some embodiments, the mounting frame 110 further includes a plurality of reinforcing ribs 114. Each reinforcing rib 114 is connected to the connecting plate 111, the first side plate 112, and the second side plate 113 and is located between the first side plate 112 and the second side plate 113. In this way, the reinforcing ribs 114 can disperse the force applied to the mounting frame 110, reduce local stress concentration, thereby prolonging the service life of the overall structure of the electric heater 10 and reducing the risk of damage due to material fatigue.

[0054] In some embodiments, the heat insulation sleeve 300 is a silica gel heat insulation sleeve 300. The silica gel heat insulation sleeve 300 is manufactured by using silica gel. The silica gel heat insulation sleeve 300 can withstand temperatures up to 200°C or above, ensuring good heat insulation effect even in long working conditions.

[0055] In addition, the silica gel heat insulation sleeve 300 is soft and elastic, and can closely fit the shape of the handle portion 220, providing a comfortable gripping feeling.

[0056] In some embodiments, the heat insulation sleeve 300 is a rubber heat insulation sleeve 300. The rubber heat insulation sleeve 300 is manufactured by using rubber. The rubber heat insulation sleeve 300 has good heat insulation performance, which can effectively prevent heat from being transmitted to the user, ensuring safe use.

[0057] The surface of the rubber heat insulation sleeve 300 usually has a certain friction, providing better anti-slip effect, increasing the safety and comfort of the user when holding.

[0058] In some embodiments, the heat insulation sleeve 300 includes a heat insulation sleeve body 310 and a protruding portion 320 connected to each other, and the heat insulation sleeve body is sleeved on the outer periphery of the handle portion 220. When the handle piece 200 is in the storage state, the heat insulation sleeve body 310 is embedded in the accommodation space 101, and the protruding portion 320 is located outside the accommodation space 101. When the handle piece 200 needs to be switched from the storage state to the unfolded state, the user can easily switch the handle piece 200 from the storage state to the unfolded state by directly grabbing the protruding portion 320, without the need for additional steps or tools, improving the convenience of use.

[0059] In some embodiments, the number of the connecting portions 210 is two, and the handle portion 220 is connected between the two connecting portions 210, and the two connecting portions 210 are oppositely and spacedly arranged. The overall shape of the handle piece 200 can be approximately U-shaped.

[0060] In this way, the two connecting portions 210 are located at both ends of the handle portion 220, forming a more stable support structure. This design can effectively prevent the handle from twisting or deforming during carrying, ensuring the absolute stability of the handle piece 200 in the unfolded state.

[0061] In addition, the two connecting portions 210 are oppositely and spacedly arranged, so that the force applied on the handle piece 200 can be evenly distributed, reducing the risk of local stress concentration and prolonging the service life of the handle piece 200 and its related components.

[0062] In some embodiments, the electric heater 10 can further include a heater, wherein the heater can be a resistance wire (coil) heater or a PTC ceramic heater, etc.

[0063] In some embodiments, the electric heater 10 relies on natural convection or forced convection to spread heat. Natural convection refers to the circulation formed by the rising of hot air and the falling of cold air; while forced convection is to accelerate the air flow by built-in fan, so that the hot air is distributed faster in the whole room.

[0064] The electric heater 10 is equipped with fins around the heater, increasing the surface area and promoting the rapid dissipation of heat.
