Description

Technical Field

[0001] The utility model relates to the field of hand dryers, and particularly to a hand dryer. Background Art

[0002] With the improvement of modern living standards, the comfort and convenience of public restrooms have attracted more and more attention. As one of the common devices in restrooms, traditional hand dryers are mostly installed on the wall by double-sided adhesive. This installation method is simple and fast. However, in the long-term use process, due to the humid environment in the restroom, when the double-sided adhesive is in long-term contact with water, its viscosity will be significantly reduced, resulting in the hand dryer not being firmly fixed on the wall and being prone to falling off. This not only affects the use but may also cause damage to the device when it falls. Moreover, after the double-sided adhesive falls off, in order to paste more firmly, it is necessary to clean the residual adhesive on the wall surface, which takes time. Therefore, in order to solve the problem that the hand dryer fixed by double-sided adhesive is easy to fall off, a new type of hand dryer is needed. Content of the Utility Model

[0003] The purpose of the utility model is to provide a hand dryer to solve the problems put forward in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: A hand dryer, including a bottom shell, with an upper cover arranged on the front surface of the bottom shell, and further including:

[0006] A heating assembly, which is arranged in the inner cavity of the bottom shell and the upper cover and is used for heating the air flowing in through the air intake hole. The heating assembly includes a heating motor, and a flow guide cylinder for guiding out hot air is arranged at the air outlet end of the heating motor;

[0007] A fixing assembly, which is arranged on the back surface of the bottom shell and is used for fixing the hand dryer on the wall surface. The fixing assembly includes a fixing chassis, magnetic adsorption parts are symmetrically arranged in the inner cavity of the fixing chassis, a fixing strip for magnetic adsorption by the magnetic adsorption parts is arranged on the back surface of the bottom shell, and a closing part is arranged on the back surface of the fixing chassis.

[0025] The present utility model provides a hand dryer as Figures 1-4 shown, which includes a bottom case 1, and an upper cover 2 is arranged on the front surface of the bottom case 1. It further includes: an air intake assembly, a heating assembly, and a fixing assembly 3;

[0026] Specifically, the air intake assembly is arranged on the top of the bottom case 1. The air intake assembly is used for the entry of external air, and the air intake assembly includes an air intake hole 101 arranged on the top of the bottom case 1;

[0027] It should be noted that a flow guide plate 4 for gas drainage is provided in the top inner cavity of the bottom shell 1. The flow guide plate 4 is used to disperse and guide the incoming gas, facilitating subsequent heating operations. The bottom shell 1 and the upper cover 2 are fixed to each other by screws.

[0028] Specifically, the heating component is arranged in the inner cavities of the bottom shell 1 and the upper cover 2. The heating component is used to heat the air flowing in through the air inlet hole 101. The heating component includes a heating motor 5, and a flow guide cylinder 6 for discharging hot air is arranged at the air outlet end of the heating motor 5.

[0029] It should be noted that the air delivery end of the flow guide cylinder 6 is inserted and connected to the inner wall of the bottom shell 1. An air outlet hole 102 for the flow guide cylinder 6 to penetrate is opened at the bottom of the bottom shell 1. The heating motor 5 and the bottom shell 1 are fixed by screws. The tapered design of the flow guide cylinder 6 is used to pressurize the heated gas, so as to facilitate the drying of the water stains on the hand by the hot air. The flow guide cylinder 6 and the air outlet end of the heating motor 5 can be connected and fixed by screws.

[0030] Specifically, the fixing component 3 is arranged on the back of the bottom shell 1. The fixing component 3 is used to fix the hand dryer on the wall surface. The fixing component 3 includes a fixing chassis 301. Magnetic adsorption parts are symmetrically arranged in the inner cavity of the fixing chassis 301. A fixing strip 305 for adsorption by the magnetic adsorption parts is arranged on the back of the bottom shell 1. A closing part is arranged on the back of the fixing chassis 301.

[0031] It should be noted that a groove for the fixing chassis 301 to penetrate is arranged on the back of the bottom shell 1. The fixing strip 305 is made of steel strip, and the bottom shell 1 is made of plastic material. The fixing strip 305 and the inner wall of the groove are fixed by hot melting.

[0032] Specifically, the closing part includes a closing plate 302. The closing plate 302 is arranged on the back of the fixing chassis 301. The closing plate 302 and the fixing chassis 301 are fixed to each other by screws. Waterproof rings 306 for preventing water vapor from entering the inside of the fixing chassis 301 are symmetrically arranged on the back of the closing plate 302. The waterproof rings 306 prevent water vapor from entering the inner cavity of the fixing chassis 301 through the screw fixing part between the closing plate 302 and the fixing chassis 301. The waterproof rings 306 are made of rubber material and are fixedly bonded to the closing plate 302. Through holes are opened at the top and bottom of the closing plate 302 and the fixing chassis 301, facilitating the insertion of expansion screws, so as to limit the fixing chassis 301 on the surface of the wall.

[0033] Specifically, the magnetic attraction part includes a magnet 303 arranged on the back surface of the fixed chassis 301. Magnet guide strips 304 are symmetrically arranged on the back side edges of the magnet 303. The magnet 303 is fixedly bonded to the inner cavity wall of the fixed chassis 301 with glue. The magnet guide strips 304 are made of steel, which is convenient for increasing the adsorption area of the magnet 303, so as to facilitate its attraction and fixation of the fixed strip 305, thereby adsorbing and fixing the hand dryer on the surface of the wall.

[0034] During actual use, by symmetrically arranging a fixing component 3 on the back surface of the hand dryer bottom shell 1, the magnet 303 in the fixed chassis 301 of the fixing component 3 is magnetically fixed to the fixing strip 305 on the back surface of the bottom shell 1, thereby fixing the hand dryer on the wall surface. In addition, the closing plate 302 is used to close the inner cavity of the fixed chassis 301. This magnetic attraction fixing form replaces the direct fixing form of the hand dryer and the wall with double-sided tape, thus avoiding problems such as the double-sided tape getting damp, its viscosity decreasing, and being easily peeled off. At the same time, it also solves the problem that the residual glue on the wall is difficult to remove and affects the fixation of the hand dryer.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
