In the description of the utility model, unless otherwise specified, "multiple" means two or more.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or a chemical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0025] An embodiment of the utility model discloses an electrical appliance, including a power assembly and a mounting shell 1 for mounting the power assembly, wherein the mounting shell 1 is partially or entirely an outer shell. Among them, there are various electrical appliances, such as electric heaters, electric fans, air conditioners, refrigerators, etc. The power assemblies in different electrical appliances are different, and are set according to the actual electrical appliances. The power assemblies are all prior art, and will not be described in detail here. In this embodiment, an electric fan is taken as an example to discuss its mounting shell 1.

[0026] See also Figure 1 The electric fan comprises a power assembly (not shown) and a mounting shell 1 for mounting the power assembly, wherein the mounting shell 1 is partially or entirely an outer shell. In this embodiment, the mounting shell 1 is a partial outer shell. Figure 1 Structure A in the middle is a partial cross-sectional view of the installation shell 1, that is, a structural schematic diagram of the outer shell.

[0027] See also Figure 2A housing of the utility model is used for electrical appliances, and in this embodiment is used for electric fans. The housing includes a housing 2 and an external protective layer 4 made of cloth or leather, and the external protective layer 4 is bonded and fixed to the outer surface of the housing 2. The housing also includes an intermediate connecting layer 3, which is arranged between the housing 2 and the external protective layer 4 and bonded to the housing 2 and the external protective layer 4 respectively. Preferably, the thickness of the external protective layer 4 is 0.2mm-1.0mm. The length of the external protective layer 4 in any direction is 5mm-20mm larger than that of the housing 2, so as to leave a length for edge processing while completely covering the housing 2.

[0028] Furthermore, the intermediate connection layer 3 is respectively bonded or hot-melt bonded to the shell 2 and the outer protective layer 4. The intermediate connection layer 3 may be a glue layer. Preferably, the intermediate connection layer 3 is made of environmentally friendly yellow glue material or other similar bonding materials. Gluing means bonding with glue. There are many methods of glue bonding. The following are three bonding methods:

[0029] Method 1: Surface spraying process. Spray glue evenly on the surface of the shell 2, and also spray glue evenly on the surface of the external protective layer 4 that needs to be bonded. After the glue has dried for a certain period of time, twenty minutes, cover the surface of the product with cloth. Since the entire surface is sprayed with glue, the bonding strength per unit area does not need to be very large, and the glue can be appropriately diluted to reduce the bonding strength of the glue. Then, the pressure between the external protective layer 4 and the shell 2 is maintained for a certain period of time, and the external protective layer 4 can be bonded to the shell 2. Generally, the pressure holding time ranges from 10 seconds to one minute. The method of spraying glue on the surface of the shell 2 can be to place the product on a fixed fixture, and use a spray gun to spray glue to cover the entire outer surface of the shell 2 that is in contact with the external protective layer 4. The same is true for spraying glue on the surface of the external protective layer 4.

[0030] Method 2: Glue brushing process. According to the shape of the product surface, brush glue with a higher concentration on the turning point or edge of the shell 2 surface to produce a greater bonding strength. Because the outer protective layer 4 is usually easy to debond at the turning point or edge, if necessary, brush glue evenly on the outer protective layer 4 to increase the firmness of the bonding. Then, keep the pressure between the outer protective layer 4 and the shell 2 for a certain period of time, so that the outer protective layer 4 can be bonded to the shell 2.

[0031] Method 3: Double-sided adhesive process. A uniform and quantitative amount of glue is applied to the whole piece of cloth or leather, and then the cloth or leather is cut into the required size and the outer protective layer 4 is cut out and covered on the shell 2. Then, the adhesive activity of the glue is activated by heating and pressure maintenance to adhere the plastic parts and the cloth.

[0032] The hot-melt bonding method is to install the outer protective layer 4 and the shell 2 on a suitable jig, and use a mold to heat-melt the outer protective layer 4 to the inner edge of the product. The outer protective layer 4 using the hot-melt method needs to have a certain elasticity and a stretching and rebounding effect, so that the cloth is stretched to fit the product completely when the mold is closed, and finally the excess cloth or leather is thermally cut off with a tool. The tool used can be an electric soldering iron head with a knife-shaped head or a similar tool, which is more efficient when cutting.

[0033] It can be understood that in some embodiments, the intermediate connection layer 3 is a continuous structure and covers the outer surface of the shell 2, for example, in the above-mentioned method 1 and method 3, the intermediate connection layer 3 is a continuous glue layer. Alternatively, the intermediate connection layer 3 can be arranged at intervals on the outer surface of the shell 2, for example, in the above-mentioned method 2, a glue with a higher concentration is brushed on the turning point or edge of the shell 2 surface, and a glue with a higher concentration is brushed on the same position on the external protective layer 4 when necessary.

[0034] Furthermore, the shell 2 includes a main shell 21 and a corner section 22, and the corner section 22 is arranged at the edge of the main shell 21. The corner section 22 is the most prone to defects such as warping of fabric or leather and bulging. In order to prevent this, the external protective layer 4 includes a main protective layer 41 and an edge protective layer 42. The size of the main protective layer 41 is consistent with the size of the main shell 21 and is glued or hot-melted to the outer surface of the main shell 21. The size of the edge protective layer 42 is larger than the size of the corner section 22 and is glued or hot-melted to the surface of the corner section 22. Preferably, the edge protective layer 42 is glued or hot-melted to the outer surface, outer side surface and part or all of the inner surface of the corner section 22. The length of the edge protective layer 42 in any direction is greater than the length of the corner section 22 by 4mm-6mm. Usually, glue is applied separately to the outer protective layer 4, i.e., the edge protective layer 42, on the inner surface of the edge section 22 at the corner of the housing 2, preferably the edge protective layer 4. The edge protective layer 42 has a higher concentration and stronger adhesion than the concentration of the spraying or brushing glue in the above-mentioned methods 1 to 3. Then, the edge protective layer 42 is evenly pressed onto the glue, and it is pressed tightly with a jig. At the folded and overlapped part of the edge protective layer 42 at the corner, the overlapping part is thermally cut off with a tool.

[0035] By implementing the utility model, the following beneficial effects are achieved:

[0036] The outer protective layer 4 of the shell of the utility model is made of cloth or leather and has a buffering effect, which can prevent the shell 2 from being damaged by collision or extrusion. In addition, the outer protective layer 4 has richer colors and styles, and the bonding operation is simple.

[0037] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the utility model; it should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, the above embodiments or technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model, that is, the embodiments described in "some embodiments" can be freely combined with any of the above and below embodiments; therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should fall within the scope of the claims of the utility model.
