Description

Technical Field

[0001] This application relates to the technical field of hair dryers, and particularly to a heat-insulating hair dryer. Background Art

[0002] After washing hair, when people need to wash up and go to bed or go out, it takes a lot of time for the hair to dry naturally or with a low-speed hair dryer. High-speed hair dryers facilitate people's lives and shorten the time for people to dry their hair. Currently, in order to be able to blow out air at different temperatures, high-speed hair dryers are usually composed of a group of heating wires and a small fan. If only the small fan rotates and the heating wires do not work, the high-speed hair dryer can only blow out cold air. When the heating wires and the small fan work simultaneously, the heating wire assembly generates heat, and the air blown by the fan becomes hot air after passing through the heating wires.

[0003] Currently, when the hair dryer is working in the heating state, the outer shell part around the air outlet of the hair dryer has a relatively high temperature, even up to 80°C, which makes it easy for users to be scalded during the use of the hair dryer. Summary of the Utility Model

[0004] In order to solve the above problems, this application provides a heat-insulating hair dryer, which is ingeniously designed and has a simple structure. By setting a heat-insulating layer, the temperature of the outer shell around the air outlet of the hair dryer is greatly reduced, which can prevent users from being scalded, and at the same time, the heat utilization rate is improved. In addition, the heat-insulating layer is thin and easy to install, and does not affect the overall size of the hair dryer. Only an installation gap for the heat-insulating layer needs to be left between the outer shell and the inner shell, and there is no need to adjust the production parameters of each component in the hair dryer due to the setting of the heat-insulating layer, which greatly saves the cost investment required for product update and upgrade. The technical solutions adopted in this application are as follows:

[0005] A heat-insulating hair dryer, comprising: a blowing part and a holding part, the blowing part and the holding part are connected; a first cavity is provided inside the holding part, and a wind generating component is provided in the first cavity, and the wind generating component is used for supplying air to the blowing part; the blowing part includes an inner shell and an outer shell, and a heat-insulating layer is provided between the inner shell and the outer shell.

[0006] By setting the heat-insulating layer, the temperature of the outer shell around the air outlet of the hair dryer is greatly reduced, which can prevent users from being scalded. At the same time, the setting of the heat-insulating layer reduces the heat released from the outer shell, enabling more heat to be released from the air outlet of the hair dryer, thus improving the heat utilization rate. In addition, the heat-insulating layer is thin and easy to install, and does not affect the overall size of the hair dryer. Only an installation gap for the heat-insulating layer needs to be left between the outer shell and the inner shell, and there is no need to adjust the production parameters of each component in the hair dryer due to the setting of the heat-insulating layer, which greatly saves the cost investment required for product update and upgrade.

[0007] In some embodiments, the heat insulation layer is provided with an adhesive layer, and the heat insulation layer is adhered to the outer wall of the inner housing through the adhesive layer.

[0008] By providing the adhesive layer, it is convenient to paste the heat insulation layer on the outer wall of the inner housing, improving the installation efficiency of the heat insulation layer. At the same time, it also ensures the connection strength between the heat insulation layer and the outer wall of the inner housing, and can prevent the heat insulation layer from falling off during the assembly process of each component of the hair dryer.

[0009] In some embodiments, the heat insulation layer is a porous vacuum silicon layer.

[0010] In some embodiments, a heat dissipation layer is further attached to the heat insulation layer.

[0011] By providing the heat dissipation layer, the heat can be evenly dispersed on the outer housing around the air outlet of the hair dryer, so that the temperature distribution of the outer housing is relatively uniform, avoiding the occurrence of too high local temperature on the outer housing and further improving the user experience.

[0012] In some embodiments, the heat dissipation layer is attached between the heat insulation layer and the inner housing.

[0013] By arranging the heat dissipation layer inside the heat insulation layer, compared with arranging the heat dissipation layer outside the heat insulation layer, the heat dissipation effect can be better, making the temperature distribution of the outer housing more uniform.

[0014] In some embodiments, the heat dissipation layer includes a metal foil layer.

[0015] In some embodiments, the metal foil layer is an aluminum foil or a copper foil.

[0016] In some embodiments, the heat dissipation layer further includes a non-metallic heat conduction layer, and the non-metallic heat conduction layer is arranged between the heat insulation layer and the metal foil layer.

[0017] In some embodiments, the non-metallic heat conduction layer is a graphene coating.

[0018] In some embodiments, the heat dissipation layer is adhered to the outer wall of the inner housing.

[0020] 1. An insulated hair dryer provided by the present application greatly reduces the temperature of the outer shell around the air outlet of the hair dryer by setting an insulating layer, which can prevent users from being scalded. At the same time, the setting of the insulating layer reduces the heat released from the outer shell, enabling more heat to be released from the air outlet of the hair dryer, thus improving the heat utilization rate. In addition, the insulating layer is thin and easy to install, without affecting the overall size of the hair dryer. Only an installation gap for the insulating layer needs to be left between the outer shell and the inner shell, and there is no need to adjust the production parameters of each component in the hair dryer due to the setting of the insulating layer, greatly saving the cost input required for product update and upgrade.

[0021] 2. An insulated hair dryer provided by the present application is facilitated to paste the insulating layer on the outer wall of the inner shell by setting an adhesive layer, which improves the installation efficiency of the insulating layer and also ensures the connection strength between the insulating layer and the outer wall of the inner shell, and can prevent the insulating layer from falling off during the assembly process of each component of the hair dryer.

[0022] 3. An insulated hair dryer provided by the present application can evenly disperse heat on the outer shell around the air outlet of the hair dryer by setting a heat - equalizing layer, so that the temperature distribution of the outer shell is relatively uniform, avoiding the occurrence of the situation where the local temperature of the outer shell is too high, and further improving the user experience.

[0023] 4. An insulated hair dryer provided by the present application can achieve a better heat - equalizing effect and make the temperature distribution of the outer shell more uniform by setting the heat - equalizing layer inside the insulating layer compared with setting the heat - equalizing layer outside the insulating layer.

[0035] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the specific implementation manners of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings in the following description are only some embodiments of the present application. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained according to these drawings, and other implementation manners can also be obtained.

[0036] To make the drawings concise, only the parts related to the present application are schematically shown in each drawing, and they do not represent the actual structure of the product. In addition, to make the drawings concise and easy to understand, in some drawings, components with the same structure or function are only schematically shown one of them, or only one of them is marked. In this document, "one" not only means "only this one", but also means the situation of "more than one".

[0037] It should also be further understood that the term "and / or" used in the specification and appended claims of the present application refers to any combination and all possible combinations of one or more of the related listed items, and includes these combinations.

[0038] In this document, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0039] In addition, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0040] Refer to Figures 1-8, this application provides a heat-insulating hair dryer, including: a blowing part 1 and a holding part 2, and the blowing part 1 is connected to the holding part 2; a first cavity (not shown in the figure) is provided inside the holding part 2, and a wind generating component is provided in the first cavity, and the wind generating component is used to supply air to the blowing part 1; the blowing part 1 includes an inner housing 3 and an outer housing 4, and a heat-insulating layer 5 is provided between the inner housing 3 and the outer housing 4. It can be understood that the hair dryer described in this application can be a rod-shaped hair dryer or a blowing rod as shown in Figure 3 , or a hair dryer of the type shown in Figure 7 , or other types of hair dryers. It should be noted that the installation position of the heat-insulating layer 5 mainly corresponds to the part of the hair dryer (when the heat-insulating layer 5 is not provided) with a higher outer shell temperature. In addition, the probability of contact between the outer shell and the user can also be taken into consideration. That is to say, it is best to set the heat-insulating layer 5 at the part of the hair dryer outer shell with a higher temperature and a greater probability of contact with the user. Without a doubt, the hair dryer described in this application is a hair dryer with a heating function, that is, a heating component 6 is provided inside the hair dryer. For example, the heating component 6 is composed of a heating support frame, a heating wire wound around the heating support frame, and a mica tube sleeved outside the heating support frame. It can be understood that for the hair dryer shown in Figure 3 , referring to Figure 4 , the heating component 6 is arranged in the blowing part 1, and the heating component 6 and the air outlet 7 are arranged in sequence along the length direction of the hair dryer. The air flow is heated by the heating component 6 and then blown out from the air outlet 7; for the hair dryer shown in Figure 7 , referring to Figure 8 , the heating component 6 is arranged in the blowing part 1, and both the heating component 6 and the air outlet 7 are annular and coaxially arranged. The air flow is heated by the heating component 6 and then blown out from the air outlet 7. The heating component 6 and the wind generating component are both prior arts and will not be elaborated here one by one.

[0041] It is worth noting that in order to improve the heat-insulating effect of the hair dryer while minimizing the adjustments and changes made to the existing hair dryer production line, that is to say, the setting of the heat-insulating layer 5 will not have a greater impact on the production parameters of the existing hair dryer components, and the parameter adjustment of the hair dryer components is small. This requires that the overall thickness of the heat-insulating layer 5 be thin, the overall weight of the heat-insulating layer 5 be light, and the heat-insulating layer 5 also needs to be easy to install. In order to install the heat-insulating layer 5, the thickness of the outer shell in the existing hair dryer can be reduced to provide an installation space for the heat-insulating layer 5, or the size of the outer housing 4 can be slightly increased, or the size of the inner housing 3 can be slightly reduced, as long as there is an installation gap for the heat-insulating layer 5 between the outer housing 4 and the inner housing 3.

[0042] The heat insulation layer 5 can be a porous vacuum silicon layer, a silicon-based aerogel layer, or other heat insulation materials. The porous vacuum silicon layer is a new heat insulation material in the form of cross-linked flakes composed of a polymer aggregate and nano-porous vacuum silica. The fine pore diameter of the nano-porous vacuum silica is 10 - 40 nm, which is smaller than the mean free path of air molecules, 68 nm, with a porosity of over 97%. The density can be as low as below 0.03 g / ml, achieving a quasi-vacuum effect. Therefore, no molecular collisions occur inside the fine pores, resulting in ultra-high heat insulation performance. The porous vacuum silicon layer is a flexible sheet heat insulation material with a thickness that can be made 0.5 - 4 mm. The porous vacuum silicon layer has a porous structure with a uniform surface. Its thermal conductivity can be as low as 0.014 W / (m·K), and the thermal resistance can be as low as 0.353 (m2·K) / W. Its operating temperature ranges from -40 to 200 °C. For the embodiment as Figure 3 shown, when the porous vacuum silicon layer is not provided, the temperature of the outer shell around the blower outlet 7 is as high as 80 °C. However, after setting a 1.5-mm-thick porous vacuum silicon layer, the temperature of the outer shell around the blower outlet 7 drops to approximately 40 °C, and the heat insulation effect is very significant. It can be understood that if a better heat insulation effect is desired, the thickness of the heat insulation layer 5 can be increased.

[0043] The silicon-based aerogel layer is a nano-porous polymer material with a three-dimensional continuous network formed by interconnected silica particles (1 - 5 nm) as the framework and gas expanding throughout its volume. It has a high porosity (85 - 99.8%) and extremely small pores (not greater than 20 nm). On the one hand, this special nano-pore network structure significantly reduces the gas-solid heat conduction efficiency of the silicon-based aerogel layer, making the thermal conductivity of the silicon-based aerogel layer significantly low, at 0.01 - 0.03 W / (m·K).

[0044] It is worth noting that by setting the heat insulation layer 5, the temperature of the outer shell around the blower outlet 7 is greatly reduced, preventing users from being scalded. At the same time, the setting of the heat insulation layer 5 reduces the heat released from the outer shell, enabling more heat to be released from the blower outlet 7, improving the heat utilization rate. In addition, the heat insulation layer 5 is thin and easy to install, without affecting the overall size of the blower. Only an installation gap for the heat insulation layer 5 needs to be left between the outer shell 4 and the inner shell 3, and there is no need to adjust the production parameters of each component in the blower due to the setting of the heat insulation layer 5, greatly saving the cost investment required for product upgrading.

[0045] It can be understood that when installing the heat insulation layer 5, it can be directly wrapped around the outer wall of the inner housing 3. After connecting the seams of the heat insulation layer 5, the installation of the heat insulation layer 5 is completed. It can also be pasted on the outer wall of the inner housing 3 by using an adhesive. Preferably, the adhesive is directly compounded with the heat insulation layer 5 to form an adhesive layer on one side of the heat insulation layer 5, and a protective film is provided outside the adhesive layer. When the heat insulation layer 5 needs to be installed, the protective film can be directly torn off for pasting, which greatly improves the installation efficiency of the heat insulation layer 5 and also ensures the connection strength between the heat insulation layer 5 and the outer wall of the inner housing 3. The adhesive can be polyacrylic acid glue, polyurethane glue, or inorganic high-temperature glue. Polyacrylic acid glue with a relatively low price is preferred. Polyacrylic acid glue can be used at a temperature of 150-160°C, showing its excellent heat resistance.

[0046] In one embodiment, a heat dissipation layer (or heat conduction layer) can also be provided between the outer housing 4 and the inner housing 3. The heat dissipation layer can be provided outside the heat insulation layer 5 or inside the heat insulation layer 5. By providing the heat dissipation layer, the heat can be evenly dispersed on the outer housing around the air outlet 7 of the hair dryer, so that the temperature distribution of the outer housing is relatively uniform, avoiding the occurrence of too high local temperature on the outer housing and further improving the user experience. It should be noted that it is preferred to set the heat dissipation layer inside the heat insulation layer 5, that is, to set the heat dissipation layer between the heat insulation layer 5 and the inner housing 3. By setting the heat dissipation layer inside the heat insulation layer 5, compared with setting the heat dissipation layer outside the heat insulation layer 5, the heat dissipation effect can be better and the temperature distribution of the outer housing can be more uniform. It can be understood that the heat insulation layer 5 and the heat dissipation layer can be provided independently of each other, that is, the two are not bonded and are only in close contact with each other. In another case, the heat insulation layer 5 and the heat dissipation layer are compounded together, and the two are compounded by an adhesive to form a composite layer. The type of adhesive can refer to the foregoing embodiments. The heat dissipation layer can also be compounded with the heat insulation layer 5 as a coating. It is easy to understand that when the heat dissipation layer is provided inside the heat insulation layer 5, the connection method between the heat dissipation layer and the outer wall of the inner housing 3 can refer to the connection method between the heat insulation layer 5 and the outer wall of the inner housing 3 when the heat insulation layer 5 is provided alone. That is to say, the heat dissipation layer can only be wrapped around the outer wall of the inner housing 3 without being bonded to it, or can be bonded to the outer wall of the inner housing 3 by an adhesive.

[0047] Specifically, the heat spreader layer can be merely a metal foil layer, such as an aluminum foil, a copper foil, or a tin foil, or merely a non-metal heat conducting layer, such as a graphene coating, a graphene film, a fullerene coating, or a fullerene film, or can also be a natural graphite film, an artificial graphite heat dissipation film, or a nano-carbon heat dissipation film. It should be noted that the heat spreader layer can also be a composite layer of a metal foil layer and a non-metal heat conducting layer. In one embodiment, the heat insulation layer 5, the non-metal heat conducting layer, and the metal foil layer are sequentially laminated together, which can greatly improve the installation efficiency of the heat insulation layer 5 and the heat spreader layer. In addition, the non-metal heat conducting layer is disposed between the heat insulation layer 5 and the metal foil layer, which can form a good protection for the non-metal heat conducting layer, prevent the non-metal heat conducting layer from being damaged, reduce the loss of the non-metal heat conducting layer, and ensure the heat spreading effect (heat conducting effect) of the heat spreader layer. In this application, the metal foil layer is preferably an aluminum foil with a relatively low price, and the non-metal heat conducting layer is preferably a graphene coating. The thickness of the aluminum foil can be 15μm, 30μm, or 250μm, and the thickness of the graphene coating can be 13μm. It can be understood that the specific types and thicknesses of the above aluminum foil and graphene coating are only some of the selections that can meet the heat insulation requirements of the hair dryer. In other embodiments, other types of heat spreader materials and thicknesses can be selected according to specific heat insulation requirements.

[0048] It should be noted that the above embodiments can be freely combined as needed. The above are only the preferred embodiments of this application. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of this application, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of this application.
