The present invention will be described in detail by examples.
As shown in fig. 1 and fig. 2, the present invention provides a schematic cross-sectional view of an automatic detergent delivery device for a washing machine, where the automatic detergent delivery device for a washing machine includes a liquid outlet 1 and a liquid inlet 2, and a containing pipe cavity 3 for containing detergent is arranged below the liquid outlet 1 and the liquid inlet 2; the piston 5 is arranged in the accommodating pipe cavity 3, the piston 5 is connected with the piston rod 6, and the piston rod 6 is connected with the gear transmission mechanism 7 and can move up and down under the drive of the gear transmission mechanism 7, so that the piston 5 is driven to move up and down.
A flexible directional valve 4 is arranged between the outlet 1 and the inlet 2, wherein a first valve port 41 of the flexible directional valve 4 is arranged at the outlet 1, and the first valve port 41 allows detergent to enter the outlet 1 from the accommodating lumen 3; a second valve port 42 of the flexible directional valve 4 is provided at the inlet 2, said second valve port 42 allowing detergent to enter the containing lumen 3 from the inlet 2; the first valve port 41 and the second valve port 42 are respectively provided on both sides of the valve body 43.
Specifically, as shown in fig. 3 and fig. 4, the flexible directional valve 4 includes a valve body 43, and a first valve port 41 and a second valve port 42 disposed on opposite sides of the valve body 43, where the first valve port 41 and the second valve port 42 are mirror images of each other and are disposed on opposite sides of the valve body 43 in a staggered manner. The first valve port 41 and the second valve port 42 are designed consistently. As shown in fig. 4, the first valve port 41 includes a first valve port seat 411, a first valve port surface 412 and a second valve port surface 413, the first valve port surface 412 and the second valve port surface 413 are mirror-symmetrically disposed on the valve port seat 411, and the first valve port surface 412 and the second valve port surface 413 are inclined surfaces inclined toward the inside of the valve port seat 411; the second valve port 42 includes a second valve port seat 421, a third valve port surface 422 and a fourth valve port surface 423, the third valve port surface 422 and the fourth valve port surface 423 are disposed on the second valve port seat 421 in a mirror symmetry manner, and the third valve port surface 422 and the fourth valve port surface 423 are inclined surfaces inclined toward the inside of the second valve port seat 421. In a normal state, the first valve port surface 412 and the second valve port surface 413 are closed toward the center of the first valve seat 411, the first valve port 41 is closed, the third valve port surface 422 and the fourth valve port surface 423 are closed toward the center of the second valve seat 421, and the second valve port 42 is closed.
The first valve port 41 and the second valve port 42 are designed in such a way that: as shown in fig. 5 (a), when the outside air pressure of the valve port surface is smaller than the inside air pressure of the valve port surface, the valve port surface is opened from the inside by the inside air pressure, and the valve port is turned on; as shown in fig. 5 (b), when the outside air pressure of the valve port surface is smaller than the inside air pressure of the valve port surface, the valve port surface is pressed from the outside by the outside air pressure, so that the valve port is closed.
As shown in fig. 1, the outer surface of the valve seat 411 of the first valve port 41 is in airtight contact with the inner surface of the liquid outlet 1, the outer surface of the valve body 43 is in airtight contact with the inner surface of the accommodating lumen 3, and the outer surface of the piston 5 is in airtight contact with the inner surface of the accommodating lumen 3, so that the air flow in the accommodating lumen 3 can only enter and exit through the first valve port 41 and the second valve port 42.
With such a design, when the piston 5 is pulled downward by the piston rod 6, as shown in fig. 6 (a), a negative pressure is generated in the accommodating lumen 3 between the piston 5 and the flexible directional valve 4, and under the pressure of the external atmospheric pressure, the two valve faces 422 and 423 of the second valve port 42 are opened by the external atmospheric pressure, so that the second valve port 42 is conducted, and the detergent can enter the accommodating lumen 3 between the piston 5 and the flexible directional valve 4 from the liquid inlet 2 through the second valve port 42. Also, since negative pressure is generated in the accommodating lumen 3, the two valve faces 412 and 413 of the first valve port 41 are pushed by external air pressure to further close toward the center of the first valve seat 411, so that the first valve port 41 is more tightly closed, and further, detergent is prevented from flowing back into the accommodating lumen 3 from the first valve port 41.
Next, when the piston 5 is pushed upward by the piston rod 6, as shown in fig. 6 (b), positive pressure is generated in the accommodating lumen 3 between the piston 5 and the flexible directional valve 4, and at this time, the outer surfaces of the two valve faces 422 and 423 of the second valve port 42 are subjected to the external atmospheric pressure, so that the two valve faces 422 and 423 are further closed to each other, and the second valve port 42 is more tightly closed; simultaneously, the first valve port surface 412 and the second valve port surface 413 of the first valve port are subjected to positive pressure effect from inside, so that the first valve port surface 412 and the second valve port surface 413 are propped open by the positive pressure in the containing cavity 3, the first valve port 41 is conducted, the detergent stored in the containing cavity 3 is pushed out of the first valve port 41 by the piston 5 from the containing cavity 3 and flows into the liquid outlet 1, and therefore, a certain amount of detergent is conveyed from the liquid inlet 2 to the liquid outlet 1 by the piston rod 6 after pulling down and pushing up the piston 5 each time.
Further, the flexible directional valve 4 may be made of rubber, and the valve body 43, and the first valve port 41 and the second valve port 42 disposed on the front and back sides of the valve body 43 may be integrally formed.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather to enable any modification, equivalent replacement, improvement or the like to be made within the spirit and principles of the invention.
