[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] Example 1: As Figures 1 to 4 As shown, a scald-proof heater includes a base plate 1, a heat sink 2, and a face shield 3. The heat sink 2 is fixedly mounted on the upper surface of the base plate 1, and the face shield 3 is located on the left side of the heat sink 2. The base plate 1 is provided with a first guardrail 4, a second guardrail 5, a third guardrail 6, and a top cover 7. The first guardrail 4 surrounds the heat sink 2 and is detachably connected to the base plate 1. The second guardrail 5 is fitted outside the first guardrail 4 and slides up and down in cooperation with the first guardrail 4. The third guardrail 6 is fitted outside the second guardrail 5 and slides up and down in cooperation with the second guardrail 5. One side of the top cover 7 is rotatably engaged with the third guardrail 6. The face shield 3 is provided with a limiting member 8 to prevent the top cover 7 from rotating.

[0032] The first guardrail 4, the second guardrail 5, the third guardrail 6, and the top cover 7 form a heat-resistant assembly. When not in use, the first guardrail 4, the second guardrail 5, and the third guardrail 6 are stored together, and the top cover 7 is attached to the outside of the third guardrail 6, taking up relatively little space (see [link]). Figure 1 In use, the first guardrail 4, the second guardrail 5, and the third guardrail 6 extend vertically. The top cover 7 covers the upper end of the third guardrail 6 and is located directly above the heat sink 2. The face shield 3 is connected to the top cover 7 via the limiting member 8 (see...). Figure 4 This design ensures that the heat-resistant components are stably positioned around the heat sink 2, preventing users from accidentally touching the heat sink 2 and providing better safety.

[0033] In this embodiment, the lower end of the base plate 1 is provided with multiple wheels 11, which makes it easy for users to move the heater flexibly.

[0034] It should be noted that the mask 3 is equipped with a control module and a heating module, which are conventional technologies in this field and will not be described in detail here; the first guardrail 4, the second guardrail 5, the third guardrail 6 and the top cover 7 can all be made of high-temperature resistant plastic, which has good heat resistance and is lightweight, making it easy for users to operate.

[0035] Example 2: Figures 4 to 8 As shown, the rest of the parts are the same as in Embodiment 1, except that the first guardrail 4 is a first U-shaped plate with the opening facing the face shield 3, and the side of the first guardrail 4 is provided with a plurality of first heat dissipation holes 41.

[0036] In this embodiment, the second guardrail 5 is a second U-shaped plate with its opening facing the face mask 3. The side of the second guardrail 5 is provided with a plurality of second heat dissipation holes 51. The inner side of the second guardrail 5 is provided with a first slide rail 52 extending in the vertical direction. The outer side of the first guardrail 4 is fixedly provided with a first slider 42, and the first slider 42 slides and engages with the first slide rail 52 in a vertical sliding cooperation.

[0037] In this embodiment, the third guardrail 6 is a third U-shaped plate with its opening facing the face mask 3. The side of the third guardrail 6 is provided with a plurality of third heat dissipation holes 61. The inner side of the third guardrail 6 is provided with a second slide rail 62 extending in the vertical direction. The outer side of the second guardrail 5 is fixedly provided with a second slider 53, and the second slider 53 slides and engages with the second slide rail 62 in a vertical sliding cooperation.

[0038] In this embodiment, the upper cover 7 is provided with a plurality of fourth heat dissipation holes 71, which helps to improve the heat dissipation effect at the top and prevent heat accumulation.

[0039] In this design, the first guardrail 4, the second guardrail 5, and the third guardrail 6 are all U-shaped to avoid obstructing the face mask 3 and to facilitate user operation of the control module on the face mask 3. The design is relatively reasonable. Preferably, multiple first sliders 42, first slide rails 52, second sliders 53, and second slide rails 62 are provided to help improve the stability of the structure.

[0040] Example 3: Figure 4 , Figure 7 and Figure 8 As shown, the rest of the parts are the same as in Embodiment 1, except that the upper end of the third guardrail 6 is recessed downward to form a groove 63. The groove 63 penetrates the two surfaces of the third guardrail 6 in the front-back direction. On the left and right sides of the groove 63, there are strip grooves 631 extending in the up-down direction. The upper cover 7 is provided with a mounting block 72 that extends into the groove 63. On both sides of the mounting block 72, there are rotating shafts 721. The two rotating shafts 721 correspond one-to-one with the two strip grooves 631. The rotating shafts 721 extend into the corresponding strip grooves 631.

[0041] When not in use, the top cover 7 can be flipped to the outside of the third guardrail 6 (see...). Figure 2 The top cover 7 can slide downwards, the mounting block 72 slides downwards along the groove 63, and the rotating shaft 721 slides downwards along the strip groove 631, ultimately causing the top cover 7 to adhere to the outside of the third guardrail 6 (see...). Figure 1 To facilitate storage and reduce space occupation, the top cover 7 is moved upwards to allow the mounting block 72 to move into the groove of the recess 63. Then, the top cover 7 is rotated to cover the upper end of the third guardrail 6 (see...). Figure 4 ).

[0042] Furthermore, a handle 73 is provided on the other side of the top cover 7. The handle 73 not only serves as a point of leverage, making it easy for users to pull up the top cover 7 to unfold the first guardrail 4, the second guardrail 5, and the third guardrail 6, but also serves as a clothes rack after the top cover 7 is placed on the third guardrail 6, making it easy for users to hang clothes and dry them with a heater.

[0043] Example 4: Figure 9 As shown, the rest of the parts are the same as in Embodiment 1, except that the limiting member 8 includes a plurality of positioning posts 81 fixedly disposed on the upper end of the face mask 3. The plurality of positioning posts 81 are distributed along the front-back direction. A limiting post 82 is fixedly disposed on the upper end surface of the positioning post 81. The diameter of the limiting post 82 is smaller than the diameter of the positioning post 81. A plurality of limiting holes 74 are provided on the upper cover 7. The plurality of limiting holes 74 correspond one-to-one with the plurality of limiting posts 82. The limiting post 82 is used to be inserted into the corresponding limiting hole 74.

[0044] When the first guardrail 4, the second guardrail 5, and the third guardrail 6 are fully extended, and the top cover 7 is placed on top of the third guardrail 6, the height of the top cover 7 is higher than the limiting member 8, meaning that the limiting post 82 is not inserted into the limiting hole 74 at this time (see...). Figure 3 Instead, when the first guardrail 4, the second guardrail 5, and the third guardrail 6 are retracted a short distance, the height of the upper cover 7 drops a short distance, at which point the limiting post 82 inserts into the limiting hole 74 to complete the locking (see...). Figure 4 ).

[0045] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
