Detailed Description
Example 1
Referring to fig. 1 to 5, a specific structure of a first embodiment of the present invention is shown, which is a fan with cooling and heating functions, the fan housing 10 has an air inlet 11 and an air outlet 12, a fan 20 is installed on the air inlet 11, a heating plate 30 and a cooling plate 40 are installed in the fan housing 10, the heating plate 30 is pivoted to one side of the air outlet 12, the cooling plate 40 is pivoted to the other side of the air outlet 12, and the heating plate 30 and the cooling plate 40 share one air outlet 12. Thereby, the fan can be in the following three states: heating, refrigerating and normal temperature air supply. 1. In the heating state, the heating plate 30 completely closes the air outlet 12, the cooling plate 40 rotates to the side of the air outlet 12 to give way, at this time, the fan 20 pumps natural wind into the fan housing 10, and the heating plate 30 heats air and then sends out warm air from the gap of the heating plate 30. 2. In the refrigerating state, the refrigerating plate 40 completely closes the air outlet 12, the heating plate 30 rotates to the side of the air outlet 12 to give way, at this time, the fan 20 pumps natural wind into the fan housing 10, the air is humidified by the refrigerating plate 40, and cold air is sent out from the gap of the refrigerating plate 40 after the air is cooled. 3. When the air is sent at normal temperature, the air outlet 12 is opened by the refrigerating plate 40 and the heating plate 30, and the refrigerating plate and the heating plate are rotated to be away from the side of the air outlet 12, so that the air outlet 12 is unblocked, and natural air sent by the fan 20 from the air inlet 11 is directly blown out from the air outlet 12.
The heating plate 30 is made of a heating support 31 and a heating wire 32 or PTC wound on the heating support 31. The refrigeration plate 40 is made of a refrigeration support 41 and a wetting body 42 mounted on the refrigeration support 41, the refrigeration plate 40 is provided with a water tank 43, the water tank 43 is provided with a small water pump or an electromagnetic valve, and the small water pump is communicated with the water tank 43 and the wetting body 42 through water pipes. For example, the wetting body 42 may be a sheet of paper having a plurality of hollowed-out holes. The water tank 43 is installed at the bottom of the fan housing 10, so that the center of gravity of the entire fan can be lowered, and the product is not easily knocked down lightly.
A first pivot shaft 33 is disposed on one side of the heating plate 30, two ends of the first pivot shaft 33 extend out of the heating plate 30 to form a first pivot point 34, and the first pivot point 34 is pivoted with the fan housing 10. A second pivot shaft 44 is disposed on one side of the cooling plate 40, two ends of the second pivot shaft 44 extend out of the cooling plate 40 to form a second pivot point 45, and the second pivot point 45 is pivoted with the fan housing 10. This design allows the heating plate 30 and the cooling to open and close the air outlet 12 like a door. In this embodiment, the first pivot 33 and the second pivot 44 are located on opposite sides of the air outlet 12, for example, on the left side and the right side, respectively, and may also be located on the upper side and the lower side, respectively. In this design manner of pivotally opening and closing the air outlet 12, the volume of the fan can be reduced as much as possible, so that the fan can be made into a rectangular or cubic structure.
In this embodiment, the first pivot 33 and the second pivot 44 are connected to the gear transmission module 50, and are driven by the gear transmission module 50 to open and close the heating plate 30 and the cooling plate 40 in a linkage manner. The gear transmission module 50 comprises a large gear 51, a first small gear 52, a first shaft transmission gear 53, a second small gear 54 and a second shaft transmission gear 55; the large gear 51 has a set of sector teeth 511, the first pinion 52 and the second pinion 54 being located on both sides of the large gear 51, the set of sector teeth 511 being periodically engaged with the first pinion 52 and the second pinion 54, the first shaft transmission gear 53 being mounted to the first pivot shaft 33 and engaged with the first pinion 52, and the second shaft transmission gear 55 being mounted to the second pivot shaft 44 and engaged with the second pinion 54. In design, the first shaft transmission gear 53 and the second shaft transmission gear 55 can be sector gears, so that the installation space occupied in assembly can be reduced, and the fan can be made smaller.
By designing the large gear 51 to have the sector gear group 511 instead of the full gear structure, when the large gear 51 rotates clockwise, the large gear 51 just starts to mesh with the first small gear 52 and finishes meshing with the second small gear 54, at this time, the large gear 51 can only drive the heating plate 30 to close the air outlet 12, no force is applied to the cooling plate 40, and when the large gear 51 rotates clockwise until the large gear 51 does not rotate, the heating plate 30 completely closes the air outlet 12. When the large gear 51 rotates counterclockwise, the heating plate 30 is driven to rotate by the first small gear 52 and the first shaft transmission gear 53 to open the air outlet 12, then the large gear 51 is meshed with the second small gear 54, and the transmission force is transmitted from the second shaft transmission gear 55 to the cooling plate 40, so that the cooling plate 40 closes the air outlet 12 in the same manner. The present invention utilizes the smart design of the gear transmission module 50, so that only the heating plate 30 and the cooling plate 40 close the air outlet 12 at a time, and when the large gear 51 is simultaneously meshed with the first small gear 52 and the second small gear 54, the air outlet 12 is in a through unobstructed state.
In this embodiment, a knob 512 is disposed on the large gear 51, and the clockwise or counterclockwise rotation of the large gear 51 is controlled by the force applied by the knob 512. Of course, the large gear 51 can also be connected with a motor, and the motor can be used for driving more labor-saving.
As shown in fig. 1 and 2, two first blocking platforms 56 and two second blocking platforms 57 are arranged at the top of the fan housing 10; when the heating plate 30 opens and closes the air outlet 12, two ends of the first shaft transmission gear 53 are respectively blocked at two first blocking tables 56; when the cooling plate 40 opens and closes the air outlet 12, two ends of the second shaft transmission gear 55 are respectively blocked by two second blocking platforms 57. The arrangement of the first and second stages 56 and 57 limits the rotation angle of the heating plate 30 and the hot and cold plate by limiting the rotation angle of the first and second shaft transmission gears 53 and 55.
The fan housing 10 has an upper housing 13, a lower housing 14, and a rear housing 15, the upper housing 13 is covered on the lower housing 14 to form an air duct, the rear housing 15 and the lower housing 14 are integrally formed, and the fan 20 is mounted on the rear housing 15. The air inlet 11 is arranged on the rear shell 15, and the air outlet 12 is arranged on the front panel of the upper shell 13.
The application method of the invention is as follows:
As shown in fig. 3, when the knob 512 is not twisted to any side, the large gear 51 is simultaneously meshed with the first small gear 52 and the second small gear 54, both the heating plate 30 and the cooling plate 40 are in an open state, the air outlet 12 is unblocked, and natural air can be sent out at this time.
As shown in fig. 4, when the knob 512 is rotated 90 degrees clockwise, the large gear 51 is meshed with the first small gear 52 to drive the first small gear 52 to rotate, and the first small gear 52 drives the first shaft transmission gear 53 to rotate, so that the heating plate 30 is driven to close the air outlet 12, and the air is heated and then sent out.
As shown in fig. 5, when the knob 512 is rotated 90 ° counterclockwise, the large gear 51 is meshed with the second small gear 54 to drive the second small gear 54 to rotate, and the second small gear 54 drives the second shaft transmission gear 55 to rotate, so as to drive the refrigeration plate 40 to close the air outlet 12, and the air is humidified, cooled and then sent out.
