Description

Technical Field

[0001] This utility model relates to a heating device, specifically a layered and zoned heating device. Background Technology

[0002] Existing electric heating technologies mainly rely on heating wires and PTC (positive temperature coefficient thermistor) materials, and are widely used in various electric heating devices, such as hair dryers, electric water heaters, and heaters. However, these traditional heating technologies have certain limitations. Due to their linear structure, heating wires, although able to heat air through direct contact, have a small contact area, resulting in low heat energy utilization and difficulty in achieving efficient heating.

[0003] On the other hand, although PTC materials can achieve heating over a large area, their heating elements are usually separated from the air by a layer of ceramic. This insulating layer prevents the heating elements from directly contacting the air, further reducing heating efficiency.

[0004] In addition, most existing heating devices use a whole-area heating method, which cannot heat different areas in layers or zones according to their needs. This leads to a lot of energy waste, especially in battery-powered wireless devices, where energy waste directly affects the device's battery life and limits the product's practicality and user experience.

[0005] Therefore, existing heating technologies cannot meet the needs of high efficiency, energy saving, and flexible control. There is an urgent need for an innovative heating technology that can improve heating efficiency and make rational use of electrical energy in order to solve the problems in existing technologies and improve product performance. Utility Model Content

[0006] To address the aforementioned problems, this invention provides a layered, zoned heating device, which effectively overcomes the shortcomings of existing technologies.

[0007] This utility model is achieved through the following technical solution: a layered, zoned heating device, comprising:

[0008] At least one layer of electrothermal material, said electrothermal material layer being composed of a material capable of generating heat by passing electricity;

[0009] At least one carrier layer is provided, the carrier layer being used to support the electrothermal material layer and the electrode, the carrier layer being made of an insulating material or a material with an insulating layer (e.g., alumina).

[0010] At least one electrode layer, the electrode layer being used to provide electrical energy to the electrothermal material layer;

[0011] The electrothermal material layer is layered and heated in zones according to a predetermined area to achieve efficient utilization of electrical energy.

[0012] As a preferred technical solution, the electrothermal material layer is composed of graphene or other materials that generate heat when energized.

[0013] As a preferred technical solution, the carrier layer is composed of ceramic material, alumina material, or other materials with an insulating layer or insulating material.

[0014] As a preferred technical solution, the electrode layer is made of silver, copper, aluminum, or other conductive materials.

[0015] As a preferred technical solution, the outer surface of the electrothermal material layer that comes into contact with the air is a planar or curved structure to increase the contact area with the air.

[0016] As a preferred technical solution, different regions of the electrothermal material layer have different resistance values ​​(i.e., there is more than one electrothermal material layer on the front or back of the carrier) or have the same resistance value (i.e., there is only one electrothermal material layer on the front or back of the carrier) to achieve customized heating according to specific needs.

[0017] As a preferred technical solution, the spacing between the heating units can be adjusted according to the product requirements.

[0018] As a preferred technical solution, the heating unit can be used alone or in combination of multiple heating units.

[0019] As a preferred technical solution, the heating area can be divided into any positive multiple of "1" to meet different power utilization needs.

[0020] The beneficial effects of this utility model are: the layered and zoned heating device of this utility model adopts a layered design of electrothermal material and carrier, adjusts the distance between heating units according to needs, and uses electrodes to provide electrical energy to achieve the effect of layered and zoned heating, which can greatly improve the utilization efficiency of electrical energy.

[0021] Compared with traditional heating technology, this device can set different resistance values ​​or the same resistance value in different areas according to specific needs, and set the distance between heating units, thereby achieving precise heating control and avoiding the waste of electrical energy.

[0022] In addition, since the heating material is in direct contact with the air and uses a planar or curved contact method, the heating efficiency of the device is significantly improved, overcoming the problem of low heating efficiency caused by the small contact area between the heating element and the air or the layer design in the prior art.

[0023] Not only is it applicable to the field of wireless hair dryers, helping to solve the battery life problem caused by battery capacity limitations, but it can also be widely used in other fields that require efficient heating, thereby providing a more energy-saving and environmentally friendly heating solution, while maintaining the miniaturization and lightweight of the device, and improving the user experience.

That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0048] Example 1:

[0049] like Figure 1 and Figure 2 As shown, the present invention provides a layered and zoned heating device, comprising two layers of electrothermal material 1 disposed on the front side of the support layer 3, and one layer of electrothermal material 1 disposed on the back side of the support layer 3, wherein the electrothermal material 1 is composed of a material capable of generating heat by passing electricity.

[0050] The carrier layer 3 is used to support the electrothermal material layer 1 and the electrode layer 2. The carrier layer 3 is made of insulating material or material with an insulating layer (such as alumina material).

[0051] Each layer of electrothermal material 1 has an electrode layer 2 on both sides, and the electrode layer 2 is used to provide electrical energy to the electrothermal material layer 1.

[0052] In this embodiment, the electrothermal material layer 1 is heated in zones according to a predetermined area to achieve efficient utilization of electrical energy. The electrothermal material layer 1 is composed of graphene or other materials that generate heat when energized. The carrier layer 3 is composed of ceramic or alumina or other materials with an insulating layer or insulating materials. The electrode layer 2 is composed of silver, copper, aluminum or other conductive materials. The outer surface of the electrothermal material layer 1 that is in contact with the air is a planar or curved structure to increase the contact area with the air. Different areas of the electrothermal material layer 1 have different resistance values ​​or are set with the same resistance value. In scenarios where two or more heating units are used in combination, the spacing between the heating units can be flexibly adjusted according to the needs of the product to achieve customized heating according to specific requirements.

[0053] Example 2:

[0054] like Figure 3 and Figure 4 As shown, the working principle of Embodiment 2 is the same as that of Embodiment 1, and the structural layout is also basically the same. The difference is that the electrothermal material layer 1 is located on one side of the carrier layer 3.

[0055] Example 3:

[0056] like Figure 5 As shown, the working principle of Embodiment 3 is the same as that of Embodiment 1, except that three layers of electrothermal material 1 are provided on both the front and back sides of the carrier layer 3, and the three layers of electrothermal material 1 are spaced apart.

[0057] Example 4:

[0058] like Figure 6 As shown, the working principle of Embodiment 4 is the same as that of Embodiment 1, and the layout is also basically the same. The difference is that the electrode layer 2 is the same length as the entire carrier layer 3 and covers both sides of the entire carrier layer 3.

[0059] Example 5:

[0060] like Figure 7 As shown, the layout of Embodiment 5 is similar to that of Embodiment 1. The difference from Embodiment 3 is that the electrode layer 2 on the two electrothermal material layers 1 on the reverse side of this embodiment connects the two electrothermal material layers 1, and the two electrode layers 2 share a common electrode on both sides.

[0061] Example 6:

[0062] like Figure 8 As shown, the layout of Embodiment 6 is similar to that of Embodiment 1, except that the electrode layer 2 on its front and back surfaces connects all the electrothermal material layers 1 together, sharing a common electrode.

[0063] Example 7:

The difference is that an electrothermal material layer 1 is provided on both the front and back sides of the carrier layer 3, and each electrothermal material layer 1 is provided on one side of the carrier layer 3, and the coverage area of ​​the electrothermal material layer on the carrier layer 3 is greatly increased.

[0065] Example 8:

[0066] like Figure 10 As shown, this embodiment is similar to embodiment 9, except that two layers of electrothermal material 1 are provided on both the upper and lower surfaces. The front and back surfaces of the carrier layer 3 are evenly divided by the electrothermal material layer 1, and each layer of electrothermal material 1 has a separate electrode layer 2.

[0067] Example 9:

[0068] like Figure 11 As shown, the principle of this embodiment is the same as that of embodiment 1, and the materials used are also the same. The difference is that the electrothermal material layer 1 covers the entire front and back of the carrier layer 3, and the electrode layer 2 is the same length as the carrier layer 3.

[0069] Example 10:

[0070] like Figure 12 As shown, this embodiment differs from embodiment 9 in that an electrode layer 2 is also provided in the middle of the electrothermal material layer 1. The electrode layer 2 divides the entire electrothermal material layer 1 into two layers, with the front and back sides having the same layout.

[0071] Example 11:

[0072] like Figure 13 and Figure 14 As shown, in this embodiment, the carrier layer 3 does not have an electrothermal material layer 1 on the front side, but only has an electrothermal material layer 1 arranged on the back side, and electrode layers 2 of equal length are arranged on both sides of the electrothermal material layer 1.

[0073] Example 12:

[0074] like Figure 15 As shown, this embodiment is similar in layout to embodiment 13. The front of the carrier is not provided with an electrothermal material layer 1, but an electrothermal material layer 1 is provided on the back. The electrothermal material layer 1 is arranged in three layers, and an electrode layer 2 is provided on both sides of each electrothermal material layer 1.

[0075] Example 13:

[0076] like Figure 16 and Figure 17As shown, the difference between this embodiment and embodiment 12 is that the electrothermal material layer 1 on the reverse side is placed on the front side, while the rest remains the same.

[0077] Example 14:

[0078] like Figure 18 As shown, the working principle of this embodiment is the same as that of embodiment 1. The difference is that in this embodiment, two layers of electrothermal material 1 are provided at intervals on both the front and back sides of the carrier layer 3, and an electrode layer 2 of equal length is provided on both sides of each layer of electrothermal material 1.

[0079] Example 15:

In this embodiment, the electrode layer 2 is the same length as the electrothermal material layer 1.
