Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the features relevant to the present invention are shown in the drawings.
Example one
The embodiment provides an automatic feeding device, which is used for automatically feeding detergents so that two feeding units can feed two kinds of detergents through one driving assembly, the structure of the automatic feeding device is simplified, and the cost of the automatic feeding device is reduced.
As shown in fig. 1 and 2, the present embodiment provides an automatic dispensing apparatus including a first dispensing unit 10, a second dispensing unit 20, and a driving assembly 30. The first dosing unit 10 is used to control the dosing of the first detergent. The second dosing unit 20 is used for controlling the dosing of the second detergent. The driving assembly 30 is used for driving the first putting unit 10 to put in the first detergent or driving the second putting unit 20 to put in the second detergent.
In this embodiment, the second dispensing unit 20 is in contact with the first dispensing unit 10, and the first dispensing unit 10 can drive the second dispensing unit 20 to dispense the second detergent. The driving assembly 30 is used for driving the first putting unit 10 to put in the first detergent. The drive assembly 30 may include a motor capable of forward and reverse rotation, or other drive assembly that may output circular motion.
The driving assembly 30 drives the first putting unit 10 to put in the first detergent, and the second putting unit 20 is driven by the first putting unit 10 to put in the second detergent, so that the driving assembly 30 drives the two putting units to finish putting in the two detergents, thereby simplifying the automatic putting device and reducing the cost. The first detergent can be a decontamination detergent, the second detergent can be a softener, and the first detergent and the second detergent can be other types of detergents, which are not described in detail herein.
Both the first dosing unit 10 and the second dosing unit 20 are capable of being in a first state of motion and a second state of motion. When the first putting unit 10 is in the first motion state, the second putting unit 20 is in the second motion state, and at this time, the first putting unit 10 does not put in the first detergent, and the second putting unit 20 puts in the second detergent. When the first putting unit 10 is in the second motion state, the second putting unit 20 is in the first motion state, and at this time, the first putting unit 10 puts the first detergent and the second putting unit 20 does not put the second detergent.
The two dosing units are in different motion states at the same time so as to dose different detergents at different times, thereby enabling the washing device to be in different washing stages at different times. For example, the first detergent may be a detergent, the second detergent may be a softener, the first dispensing unit 10 is in the second motion state before the laundry is cleaned, and the detergent is dispensed, and the second dispensing unit 20 is in the first motion state and the softener is not dispensed. After the clothes are decontaminated, the second feeding unit 20 is in the second motion state, and the softener is fed, and at this time, the first feeding unit 10 is in the first motion state, and the decontamination detergent is not fed.
In this embodiment, the first and second dispensing units 10 and 20 have the same structure, and in other embodiments, the first and second dispensing units 10 and 20 may have different structures, as long as the two kinds of detergents can be dispensed.
As shown in fig. 2, in the present embodiment, the first and second launching units 10 and 20 each comprise a gear 1 and a follower 2, and the gear 1 and the follower 2 are rotationally connected. The gear 1 of the first feeding unit 10 is a driving gear 11, the gear 1 of the second feeding unit 20 is a driven gear 12, and the driving gear 11 is engaged with the driven gear 12. The follower 2 of the first drop unit 10 is a first follower disc and the follower 2 of the second drop unit 20 is a second follower disc.
As shown in fig. 3, in this embodiment, in order to improve the rotation stability of the driving gear 11, the driven gear 12, the first follower disk and the second follower disk, the automatic feeding device further includes a connecting plate 40, a shaft hole is formed in the connecting plate 40, a rotatable rotating shaft 50 is disposed in the shaft hole, and the driving gear 11, the driven gear 12, the first follower disk and the second follower disk are all rotatably connected to the connecting plate 40 through the rotating shaft 50. The rotating shaft 50 connected with the driving gear 11 is in transmission connection with an output shaft of the driving assembly 30, and is in transmission connection with the driving gear 11, and the follower 2 can rotate relative to the rotating shaft 50.
As shown in fig. 2, the follower 2 has a clearance 3 with the gear 1, so that the follower 2 and the gear 1 can move relatively.
In this embodiment, the first direction is defined as V 1 Clockwise as shown, the second direction being V 2 The counterclockwise direction is shown, although in other embodiments the first direction is counterclockwise and the second direction is clockwise.
The driving assembly 30 drives the driving gear 11 to rotate around its axis, the driving gear 11 drives the driven gear 12 to rotate, and when the driving gear 11 follows arrow V in fig. 2 1 When moving in the direction shown (clockwise), it drives the driven gear 12 in the direction of arrow V in fig. 2 2 The direction of movement shown (counterclockwise).
When the dosing unit is in the first state of motion, the gear wheel 1 is moved in the first direction, i.e. in fig. 2 (clockwise), and the follower 2 does not move with the gear wheel 1. When the dosing unit is in the second state of motion, the gear wheel 1 moves in a second direction (i.e. counter clockwise in fig. 2) and the follower 2 moves with the gear wheel 1.
In order to realize the relative movement and relative rest of the follower 2 and the gear 1, the end face of the gear 1 is provided with a containing groove, the follower 2 is rotatably arranged in the containing groove, a gap 3 with variable size is arranged between the follower 2 and the groove wall of the containing groove, and a braking part 8 is arranged in the gap 3. Specifically, the brake 8 in the first drop unit 10 is a first brake, the brake 8 in the second drop unit 20 is a second brake, and the brake 8 may be a ball or a roller. The cross-section of the receiving groove is circular in this embodiment.
The braking member 8 is slidable within the gap 3 to a first position and a second position, the gap 3 in the first position being smaller in size than the gap 3 in the second position.
When the gear 1 moves along the first direction, the braking part 8 is acted by the friction force of the gear 1 and can move to the first position of the gap 3, the size of the gap 3 at the first position is small, the braking part 8 is in contact with the follower 2 and the gear 1, and the pressure borne by the follower 2 is large due to the small size of the gap 3 at the first position, so that the friction force among the follower 2, the gear 1 and the follower 2 is large, and the follower 2 moves along with the gear 1 under the action force of the braking part 8.
When the gear 1 moves along the second direction, the braking member 8 can move to the second position of the gap 3 by the friction force of the gear 1, the size of the gap 3 in the second position is larger, and the braking member 8 is in contact with the follower 2 and the gear 1, but because the size of the gap 3 in the second position is larger, the pressure on the follower 2 is smaller, the friction force between the follower 2 and the gear 1 and the follower 2 is smaller, the force on the follower 2 is not enough to rotate the follower 2, and therefore the follower 2 does not move along with the gear 1.
Since the brake 8 is still in contact with the gear wheel 1 when in the second position, the brake 8 can still be brought into the first position by the friction of the gear wheel 1 when the gear wheel 1 is moved again in the first direction.
The edge of the follower 2 is provided with a braking groove 31, the groove wall of the braking groove 31 and the groove wall of the accommodating groove are provided with a gap 3, and the edge of the follower 2 and the groove wall of the accommodating groove are also provided with a gap 3. The braking member 8 is disposed in the braking groove 31 and can be located at a first position and a second position. Specifically, the braking groove 31 may be a wedge-shaped groove, the groove walls of the braking groove 31 include a first groove wall 311 and a second groove wall 312 arranged in an L-shaped structure, the first groove wall 311 is arranged along the radial direction of the follower 2, and the second groove wall 312 is arranged at an acute angle or a right angle with respect to the first groove wall 311, so that the gap 3 between the second groove wall 312 and the groove wall of the accommodating groove is gradually reduced, that is, the position of the braking groove 31 close to the first groove wall 311 is the second position, and the position of the braking groove 31 far from the first groove wall 311 is the first position. In order to secure the braking effect of the braking member 8, a plurality of braking grooves 31 are provided along the circumferential direction of the follower 2.
Taking the first releasing unit 10 as an example, when the driving gear 11 is along V as shown in FIG. 2 1 When the first brake piece moves in the clockwise direction, the first brake piece moves to the second position under the action of the friction force of the driving gear 11, the size of the gap 3 at the second position is large, the first follow-up disc is separated from the driving gear 11, and the first follow-up disc does not move along with the driving gear 11.
When the driving gear 11 is along V as shown in FIG. 2 2 When the movable brake moves in the direction (anticlockwise), the first brake is acted by the friction force of the driving gear 11 and moves away from the first groove wall311 to a first position, the gap 3 in the first position is of a smaller size, so that the first follower disk and the drive gear 11 move integrally.
In the present embodiment, in order to smoothly bring the stopper 8 into the second position, the stopper 8 is connected to the follower 2 through the elastic member 4. When the braking member 8 is in the first position, the elastic member 4 is in tension and the gear 1 is along V as shown in fig. 2 2 Moving in the direction (anticlockwise), the braking member 8 is brought into the second position by the pulling force and friction force of the elastic member 4. Specifically, the elastic member 4 connected to the first brake disk is a first elastic member, and the elastic member 4 connected to the second brake disk is a second elastic member. The elastic element 4 may be a spring or a leaf spring.
In this embodiment, the automatic dispensing device further includes a storage unit 60, the storage unit 60 is used for storing detergent, the first dispensing unit 10 and the second dispensing unit 20 are both connected to the storage unit 60, and the first dispensing unit 10 and the second dispensing unit 20 both dispense detergent by controlling the storage unit 60.
The storage unit 60 includes a pump housing 7, a link 5, and a plunger 6. The pump case 7 is used for placing detergent, and the lower end of the pump case 7 is provided with a liquid outlet 72 with a liquid outlet one-way valve. The plunger 6 is arranged in the pump shell 7, the follower 2 is connected with one end of the connecting rod 5, and the other end is connected with the plunger 6. When the dosing unit is in the first state of motion, the follower 2 does not move with the gear 1, so that the link 5 is stationary. When the releasing unit is in the second motion state, the follower 2 moves along with the gear 1, so as to drive the connecting rod 5 to move up and down, and the air pressure in the pump shell 7 is changed in the process of moving the plunger 6 up and down, so that the liquid outlet of the liquid outlet 72 is realized.
Wherein, the pump case 7 for placing the first detergent is a first pump case, and the pump case 7 for placing the second detergent is a second pump case. A first plunger is arranged in the first pump shell and provided with a first liquid inlet with a liquid inlet one-way valve, and a second plunger is arranged in the second pump shell and provided with a second liquid inlet with a liquid inlet one-way valve. The link 5 connected to the first plunger is a first link, and the link 5 connected to the second plunger is a second link. The first connecting rod is connected with the first follower and is parallel to the end surface of the driving gear 11, and the second connecting rod is connected with the second follower and is parallel to the end surface of the driven gear 12, so that the connecting rod 5 moves up and down in the process that the follower 2 rotates along with the gear 1.
Specifically, the follower 2 may be provided with a convex pillar 21, the link rod 5 is connected with the convex pillar 21, an end of the link rod 5 connected with the convex pillar 21 is a collar 51, the collar 51 is sleeved on the convex pillar 21, and the convex pillar 21 can rotate relative to the collar 51, so that the link rod 5 moves up and down in the process of circular motion of the convex pillar 21. Specifically, the convex column 21 disposed on the first follower disk is a first convex column, and the convex column 21 disposed on the second follower disk is a second convex column.
In this embodiment, the pump casing 7 may further be provided with a liquid inlet 71 having a liquid inlet check valve, so that the pump casing 7 can be filled with liquid during the upward movement of the plunger 6. Specifically, the liquid outlet 72 provided in the first pump case is a first liquid outlet, and the liquid outlet 72 provided in the second pump case is a second liquid outlet.
The automatic releasing device provided in the embodiment is arranged along the V of the follower 2 2 In the process of moving in one circle, the liquid outlet of the liquid outlet 72 and the liquid inlet of the liquid inlet 71 can be automatically realized.

Further, since the stroke of the upward movement and the stroke of the downward movement of the plunger 6 are the same, the liquid inlet amount of the liquid inlet 71 and the liquid outlet amount of the liquid outlet 72 are the same. Therefore, the pump shell 7 does not need to be separately injected with the washing liquid, and a device for injecting the washing liquid into the pump shell 7 does not need to be separately arranged, so that the structure of the automatic feeding device is simplified.
