Description

Technical Field

[0001] The utility model relates to the field of hand dryers, in particular to an air outlet structure of a hand dryer. Background Art

[0002] In public restrooms, restaurants, shopping malls and other public places, hand dryers are widely used as a convenient and hygienic hand drying device. Traditional wall-mounted hand dryers usually include a main body, an air outlet sleeve and a heating unit. When a user puts their hand under the air outlet sleeve, the hand dryer is activated by a sensor, and the hot air generated by the heating unit blows towards the user's hand through the air outlet sleeve to quickly dry the hand. The existing wall-mounted hand dryer air outlets are generally directly exposed in design. This causes mosquitoes and other small insects to easily drill into the hand dryer when it is not working. When these mosquitoes enter the hand dryer, they may die inside, resulting in their corpses staying inside the air outlet sleeve. When the user uses the hand dryer, the internal fan blows out hot air and blows out these mosquito corpses together, which affects the user experience and causes environmental hygiene problems. Therefore, in order to solve the above problems, a new air outlet structure for hand dryers is needed. Content of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides an air outlet structure of a hand dryer as shown in Figures 1-4 Figure 6, which includes an air outlet guide cylinder 1. A base 2 and an upper cover 3 for fixing the air outlet guide cylinder 1 are arranged on the outer side of the air outlet guide cylinder 1. An air outlet 201 is arranged on the inner wall of the base 2. The air outlet structure further includes a filtering member and a fixing member;

[0022] It should be noted that the air outlet guide cylinder 1 and the base 2 are fixedly connected by screws, and the upper cover 3 and the base 2 can be fixed by screws;

[0023] Specifically, the filtering member is arranged at the bottom of the base 2 and outside the air outlet 201. The filtering member is used to prevent mosquitoes from entering the interior of the air outlet guide cylinder 1. The filtering member includes a fixed mesh plate 4, and a blocking net 401 for protection is arranged on the inner wall of the fixed mesh plate 4;

[0024] It should be noted that a plurality of ventilation round holes are formed on the front surface of the fixed mesh plate 4 to prevent large-sized insects from entering the interior of the air outlet guide cylinder 1. The blocking net 401 is made of stainless steel material, and its blocking radius is 0.05 mm. The side of the blocking net 401 is fixedly connected to the fixed mesh plate 4 by glue;

[0025] Specifically, the fixing members are symmetrically arranged at both ends of the fixed mesh plate 4. The fixing members are used for locking and disassembling the filtering member. The fixing members include connecting plates 5 arranged at the ends of the fixed mesh plate 4. Square sleeves 6 are arranged on the sides of the connecting plates 5, and the ends of the square sleeves 6 are inserted and connected to the bottom of the base 2;

[0026] It should be noted that both the connecting plate 5 and the fixed mesh plate 4 are made of polypropylene material. A rectangular groove for inserting the square sleeve 6 is formed on the side of the connecting plate 5. The inner wall of the rectangular groove is fixedly connected to the outer side of the square sleeve 6 by glue. A rectangular through hole for inserting the square sleeve 6 is formed on the bottom of the base 2;

[0027] A locking portion 7 is arranged at the insertion part of the base 2 and the square sleeve 6;

[0028] Specifically, the locking part 7 includes a fixed groove plate 701 arranged on the side of the air outlet guide tube 1. An elastic block 702 is arranged on the inner wall of the fixed groove plate 701. A movable plate 703 is arranged on the side of the elastic block 702. A locking protrusion 704 for inserting through the side of the square sleeve 6 is arranged on the side of the movable plate 703. An insertion rod 705 for pushing the locking protrusion 704 to unlock is arranged in the inner cavity of the square sleeve 6.

[0029] It should be noted that the fixed groove plate 701 and the side of the air guide tube 1 are fixed by glue bonding. The notch of the fixed groove plate 701 is close to the air outlet 201. The elastic block 702 and the groove wall are fixed by glue bonding. The movable plate 703 and the elastic block 702 are fixed by glue bonding. Both the locking protrusion 704 and the movable plate 703 are made of stainless steel and are integrally cast. The end of the locking protrusion 704 is spherical, which is convenient for it to insert into and move out of the side of the square sleeve 6.

[0030] Specifically, the elastic block 702 is a rubber block. An inclined cutting edge for assisting the square sleeve 6 to insert into the inner cavity of the fixed groove plate 701 is arranged on the side of the end of the square sleeve 6. When the square sleeve 6 is inserted into the inner cavity of the fixed groove plate 701, the inclined cutting edge is convenient for squeezing the locking protrusion 704, so that the elastic block 702 is deformed. In the state where the elastic block 702 is not squeezed, the movable plate 703 is in contact with the outer side of the square sleeve 6. A locking hole for the locking protrusion 704 to penetrate is arranged on the outer side of the square sleeve 6, and an inclined inner wall for assisting the locking protrusion 704 to move out of the locking hole is arranged at the top of the locking hole. The arrangement of the inclined inner wall is convenient for the insertion rod 705 to squeeze the locking protrusion 704 and limit it in the locking hole. The arrangement of the inclined inner wall is convenient for pulling out the square sleeve 6, and the locking protrusion 704 moves out of the locking hole along the inclined inner wall.

[0031] An inclined cutting edge for squeezing the locking protrusion 704 is arranged at the end of the insertion rod 705, which is convenient for squeezing the locking protrusion 704 into the locking hole.

[0032] During the actual use process, a filtering component is arranged at the air outlet 201 of the air outlet guide tube 1. The locking part 7 in the fixing component at the bottom of the base 2 locks the connecting plate 5 connected to the fixing mesh plate 4. Press the insertion rod 705, so that the inclined side of the insertion rod 705 squeezes the locking protrusion 704, making the locking protrusion 704 retract into the locking hole. Pull out the square sleeve 6 to realize the disassembly of the fixing mesh plate 4. Insert the square sleeve 6 into the inner cavity of the fixed groove plate 701. The locking protrusion 704 passes through the locking hole and enters the inner cavity of the square sleeve 6 to realize the locking of the square sleeve 6. The fixing mesh plate 4 and the intercepting net 401 in the filtering component are used to intercept mosquitoes, preventing mosquitoes from entering the air outlet guide tube 1 and polluting the inside of the air outlet guide tube 1, so as to avoid the air outlet guide tube blowing out the mosquito corpses inside during the operation of the hand dryer, which affects the use of the hand dryer.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
