Detailed Description
The present invention will be described in further detail with reference to examples and drawings, but the present invention is not limited thereto.
Referring to fig. 1 to 4, the hand dryer using solid dry particles according to the present invention includes a support table 1, a solid dry particle spraying device 2 disposed on the support table 1, a hand drying box 3, and a solid dry particle collecting device 4, wherein the solid dry particle spraying device 2, the hand drying box 3, and the solid dry particle collecting device 4 are sequentially disposed from top to bottom and are communicated with each other. The solid dry particle spraying device 2 comprises a box body 2-1, a solid dry particle storage mechanism arranged in the box body 2-1 and a spraying driving mechanism used for driving the solid dry particles in the solid dry particle storage mechanism to be sprayed to the hand drying box 3. The hand drying box 3 is provided with an inlet and an outlet 3-1 through which both hands of people can pass. The solid dry particle collecting means 4 comprises a collecting box 4-1 disposed below the hand drying box 3.
Referring to fig. 1-4, two storage spaces are arranged in the box body 2-1, and are arranged in parallel and separated by a partition plate 2-10; one storage space is used for storing the solid dry particles, so that the solid dry particle storage mechanism is formed; the other storage space is used for placing the spraying driving mechanism; wherein, the storage space for storing the solid dry particles is a first storage space 2-2, and the storage space for placing the spraying driving mechanism is a second storage space 2-3.
Referring to fig. 1 to 4, the box body 2-1 is provided with a feed inlet 2-4 at the upper end of the first storage space 2-2, so that it is convenient for a worker to add the solid dry particles into the solid dry particle storage mechanism.
Referring to fig. 1-4, the spraying driving mechanism comprises a fan 2-5 arranged in a second storage space 2-3, a first opening 2-7 arranged on the partition 2-10 for connecting the first storage space 2-2 with the second storage space 2-3, and a second opening 2-8 arranged on the box body 2-1 for connecting the second storage space 2-3 with the hand drying box 3, wherein a first baffle 2-9 is arranged on the first opening 2-7, and the first baffle 2-9 is rotatably connected to the partition 2-10; a second baffle 2-11 is arranged on the second opening 2-8, and the second baffle 2-11 is rotatably connected to the box body 2-1; a synchronous mechanism for driving the first baffle 2-9 and the second baffle 2-11 to synchronously move so as to promote the first opening 2-7 and the second opening 2-8 to be simultaneously opened or closed is arranged between the first baffle 2-9 and the second baffle 2-11. Thus, when both hands need to be dried, the fan 2-5 can be started, and the wind power of the fan 2-5 pushes the second baffle 2-11 at the second opening 2-8 to turn outwards, so that the second opening 2-8 is opened. The second baffle 2-11 is also driven by the synchronizing mechanism to turn the first baffle 2-9 towards the second storage space 2-3 while turning outwards, so as to open the first opening 2-7. Thus, the solid dry particles in the solid dry particle storage mechanism enter the second storage space 2-3 along the first opening 2-7 and are sprayed into the hand drying box 3 along the second opening 2-8 under the driving of the wind power of the fan 2-5. When the hands do not need to be dried, the fan 2-5 is turned off, and the first baffle 2-9 and the second baffle 2-11 return to the original positions under the action of the synchronizing mechanism due to the fact that wind power of the fan 2-5 does not exist, so that the first opening 2-7 and the second opening 2-8 are closed.
Referring to fig. 1-4, the synchronizing mechanism includes a torsion spring (not shown in the drawings) disposed at the first barrier 2-9 and a link 2-12 for connecting the first barrier 2-9 and the second barrier 2-11, wherein the link 2-12 is installed in the case 2-1 through a rotating shaft 2-6; the two ends of the torsion spring act on the partition plates 2-10 and the first baffle plates 2-9; under the state that solid dry particles are not sprayed, the elasticity of the torsion spring enables the first baffle 2-9 to be closed on the first opening 2-7, enables the first baffle 2-9 to be tightly propped against one end of the connecting frame 2-12, enables the other end of the connecting frame 2-12 to be tightly propped against the second baffle 2-11, and enables the second baffle 2-11 to be closed on the second opening 2-8; under the state of spraying solid dry particles, the second baffle plate 2-11 opens the second opening 2-8 under the action of wind power, and pushes the first baffle plate 2-9 to overcome the elasticity of the torsion spring to open the first opening 2-7 through the connecting frame 2-12. Thus, when the fan 2-5 is started, and when the wind power of the fan 2-5 is larger than the acting force of the torsion spring on the second baffle 2-11, the wind power of the fan 2-5 pushes the second baffle 2-11 away, so that the second baffle 2-11 is turned over counterclockwise, and the second opening 2-8 is opened. The second baffle 2-11 also drives the connecting frame 2-12 and the first baffle 2-9 to rotate counterclockwise against the elasticity of the torsion spring while turning over, so as to open the first opening 2-7, so that the solid dried particles in the first storage space 2-2 enter the second storage space 2-3, and enter the hand drying box 3 through the second opening 2-8 under the driving of the wind force of the fan 2-5. After the hands dry, the fan 2-5 is turned off, and the first baffle 2-9 and the second baffle 2-11 rotate clockwise under the elasticity of the torsion spring and return to the original positions, thereby closing the first opening 2-7 and the second opening 2-8. Like this, fan 2-5's wind-force both can drive the entering solid dry particle in the second parking space 2-3 moves to in the hand drying box 3, can blow on people's both hands along with solid dry particle again to accelerate the evaporation of the drop of water on the both hands, improve drying efficiency.
Referring to fig. 1-4, a torsion spring (which is not shown in the drawings) is further disposed on the rotating shaft 2-6 of the connecting frame 2-12, and two ends of the torsion spring act on the box body 2-1 and the second baffle 2-11; under the state of non-spraying solid particles, the elasticity of the torsion spring urges the second baffle 2-11 to close on the second opening 2-8; under the state of spraying solid particles, the second baffle 2-11 overcomes the elasticity of the torsion spring to open the second opening 2-8 under the action of wind force. Thus, the torsion springs arranged at the first baffle 2-9 and the second baffle 2-11 make the first baffle 2-9 and the second baffle 2-11 respectively cling to the first opening 2-7 and the second opening 2-8, and only when the wind power of the fan 2-5 is greater than the elasticity of the torsion springs at the first baffle 2-9 and the second baffle 2-11, the wind power of the fan 2-5 can make the first baffle 2-9 and the second baffle 2-11 rotate, so that the first opening 2-7 and the second opening 2-8 are opened, and the solid particles in the first storage space 2-2 are put into the hand drying box 3.
Referring to fig. 1-4, the box body 2-1 is provided with a guide plate 2-13 on the first storage space 2-2, the projected area of the guide plate 2-13 on the bottom of the box body 2-1 is consistent with the bottom area of the first storage space 2-2, one end of the guide plate 2-13 is arranged at the lower end of the first opening 2-7, and the other end of the guide plate 2-13 is inclined upwards in the direction away from the first opening 2-7; the solid dry particles are stored in the first storage space 2-2 at a position above the guide plate 2-13. Thus, the dried solid particles stored in the first storage space 2-2 above the guide plate 2-13 have a tendency to slide down the guide plate 2-13 to the first opening 2-7, and when the first opening 2-7 is opened, the dried solid particles in the first storage space 2-2 slide down the guide plate 2-13 and pass through the first opening 2-7 into the second storage space 2-3. This allows the dry solid particles in the first storage space 2-2 to smoothly enter the second storage space 2-3.
Referring to fig. 1-4, a first guide mechanism is arranged between the second opening 2-8 and the hand drying box 3, a second guide mechanism is arranged between the collecting box 4-1 and the hand drying box 3, and the first guide mechanism and the second guide mechanism are funnel-shaped guide grooves 2-14. The first and second guide means are provided for guiding the solid dried particles smoothly into the hand drying box 3 or the collection box 4-1.
Referring to fig. 1-4, the collection box 4-1 is in the shape of an inverted frustum pyramid, and a movable door 4-2 is arranged at the lower end of the collection box 4-1; after the collection box 4-1 collects the solid dry particles, the worker takes out the solid dry particles and treats them uniformly.
Referring to fig. 1-4, a movable baffle 3-2 is arranged at an inlet/outlet 3-1 in the hand drying box 3, and the movable baffle 3-2 is rotatably connected in the hand drying box 3. When both hands stretch into hand drying box 3's in-process, people's both hands also can promote adjustable fender 3-2 court hand drying box 3 is inside rotates certain angle, like this, fan 2-5's wind-force drives when the dry granule of solid sprays on both hands, owing to have adjustable fender 3-2 blocks, consequently the dry granule of solid can not follow fly out in importing and exporting 3-1.
