The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

Reference is now made to the dispensing device 10, the dispensing assembly 100 and the washing apparatus 1000 according to an embodiment of the present invention. For example, the dispensing device 10 may be used in washing devices having a water inlet system, such as a washing machine, a dishwasher, a wash-stand, or a sink.

Referring to fig. 1 and 2, a dispensing device 10 according to an embodiment of the present invention, the dispensing device 10 is used for dispensing lotion and may include a dispensing pump 1 and a driving assembly 2. Wherein the detergent can be liquid detergent such as laundry detergent, softener and the like.

Referring to fig. 3-5, the dispensing pump 1 includes a pump casing 11 and a pump body 12, the pump body 12 is disposed in the pump casing 11, wherein the pump body 12 may be rotatably disposed in the pump casing 11, or the pump body 12 may also be movably disposed in the pump casing 11, a liquid inlet 116 and a liquid outlet 117 are formed on the pump casing 11, the driving assembly 2 is connected to the pump body 12, the driving assembly 2 includes a driving member 21, the driving member is disposed outside the pump casing, and the driving member 21 drives the pump body 12 to move.

It can be understood that, the manual dispensing device in the related art, its principle is that this kind of reciprocating motion device who changes the extraction and exhaust device cavity volume proportion of adopting similar plunger pump realizes imbibition and flowing back, and what manual dispensing device's driving piece was located the pump case, and the motion space of driving piece receives the restriction of pump case size, leads to the motion stroke of driving piece little, and the single volume of puting in the device is few, and the number of times of puting in is many, and user experience is poor.

According to the dispensing device 10 provided by the embodiment of the invention, the driving part 21 is arranged at the outer side of the pump shell 11, so that the movement space of the driving part 21 is not limited by the size of the pump shell 11, the movement stroke of the driving part 21 is favorably increased, the space in the pump shell can be fully utilized, the single dispensing amount of the dispensing device 10 can be increased, the dispensing times are favorably reduced, the dispensing device can meet the requirements of large-capacity washing equipment such as a washing machine, a dish washing machine and the like on the dispensing of the washing agent, and the use experience of users is favorably improved.

Referring to fig. 3-5, in some embodiments of the invention, pump body 12 is rotatably disposed within pump housing 11 such that a suction area 114 and a discharge area 115 are formed within pump housing 11, suction area 114 corresponding to liquid inlet 116 and discharge area 115 corresponding to liquid outlet 117. For example, the user can manually drive the driving member 21 to rotate so as to drive the pump body 12 to rotate, thereby realizing the semi-automatic dispensing of the dispensing device 10, i.e. manually dispensing a certain amount of lotion.

It will be appreciated that when the dispensing device 10 is in the initial state (no lotion is present in the discharge area 115), negative pressure is generated in the suction area 114 and positive pressure is generated in the discharge area 115 when the rotary drive member 21 rotates the pump body 12, and the lotion at the inlet 116 flows to the discharge area 115 under the effect of the pressure difference, during which the suction at the inlet 116 and the discharge at the outlet 117 of the dispensing pump 1 are not synchronized in time until the discharge of lotion at the outlet 117 is possible, after which, i.e. when the dispensing device 10 is operating normally, the suction at the inlet 116 and the discharge at the outlet 117 of the dispensing pump 1 are synchronized in time when the rotary drive member 21 rotates the dispensing pump to dispense lotion.

The inventor found in practical studies that the principle of the manual dispensing device in the related art is to use a reciprocating device like a plunger pump to change the volume ratio of the cavity of the pumping and discharging device to achieve the liquid suction and the liquid discharge, and the liquid suction and the liquid discharge are alternately performed, in other words, the liquid suction and the liquid discharge of the manual dispensing device in the related art are located in the same area and are not synchronized in time, the liquid discharge force is provided by manual pressing, the power required by liquid pumping is provided by spring resetting, and the device is similar to a pressing and putting device for shampoo or hand sanitizer and the like in daily life, but because the washing equipment such as a washing machine, a dish washing machine and the like has larger capacity, the quantity of the washing agent required for each washing is far larger than the single use quantity of the hand sanitizer or the shampoo in daily life, this requires the pump chamber to be made larger or the number of user presses to be increased, which results in a poor user experience.

The dispensing device 10 according to the embodiment of the present invention can control the rotation angle of the driving member 21 to achieve quantitative control of the dispensing amount of the lotion, and since the liquid suction area 114 and the liquid discharge area 115 of the dispensing pump 1 are located in different areas, when the dispensing device 10 is working normally, the liquid suction at the liquid inlet 116 and the liquid discharge at the liquid outlet 117 of the dispensing pump 1 are synchronized in time, thereby ensuring that the throwing amount of the throwing pump 1 is not limited by the volume of the throwing pump 1, being beneficial to increasing the amount of the washing agent thrown by the throwing device 10 in one time, further, on the basis of a certain volume of the throwing device 10, the single throwing amount of the throwing device 10 can be increased, the throwing precision of the single throwing can be ensured, the throwing times can be reduced, the precision requirement can be ensured, can meet the requirement of large-capacity washing equipment 1000 such as a washing machine, a dish washing machine and the like on the putting of the washing agent, and is beneficial to improving the use experience of users.

Alternatively, in some examples, referring to fig. 2 and 3, the pump housing 11 includes a housing portion 111 and an end cap 112, the end cap 112 is detachably disposed at an open end of the housing portion 111, the housing portion 111 and the end cap 112 define a relatively sealed pump chamber 113 therebetween (see fig. 5), and the pump body 12 is rotatably disposed in the pump chamber 113. It will be appreciated that the mounting and replacement of the pump body 12 is facilitated by the end cap 112 being removably disposed at the open end of the housing portion 111. For example, the end cap 112 may be connected to the housing portion 111 by a snap, rivet, or threaded fastener connection.

In some embodiments of the present invention, as shown with reference to fig. 1 and 6, the driver 21 is rotatable between a first position (see fig. 6) and a second position (see fig. 13), and during rotation from the first position to the second position, the driver 21 drives the pump body 12 in motion to perform suction and discharge (see fig. 5). It can be understood that the rotation angle of the driving member 21 from the first position to the second position is related to the rotation angle of the pump body 12, and the rotation angle of the pump body 12 can be controlled by controlling the rotation angle of the driving member 21 from the first position to the second position, so that the control of the single throwing amount of the throwing device 10 is conveniently realized, and the structure is simple and the operation is convenient.

In some alternative embodiments of the invention, illustrated with reference to fig. 6-8, the axis of rotation of the driver 21 extends substantially horizontally, the first position being above the second position. For example, as shown in fig. 6 to 8, the rotational axis of the driver 21 is L, and the rotational axis L extends in the left-right direction. It can be understood that, driving piece 21 is the pitch arc around the pivoted orbit of axis of rotation, through making the top that first position is located the second place, the user can press driving piece 21 so that driving piece 21 rotates to the second place by first position, the user application of force of being convenient for puts in device 10 in the drive and puts in lotion, and can increase driving piece 21's motion stroke, be favorable to further improving the single volume of putting in, reduce user's the number of times of putting in, improve user's use experience. Of course, the present invention is not limited thereto, and the first position may be located below the second position.

In some alternative embodiments of the invention, and as shown with reference to fig. 6, the angle between the first position and the second position is no greater than 120 °. In other words, the angle between the line connecting the first position and the center of rotation of the driver 21 and the line connecting the second position and the center of rotation of the driver 21 is not more than 120 °. That is, the rotational angle of the driver 21 from the first position to the second position or from the second position to the first position is not more than 120 °. Therefore, the included angle between the first position and the second position is not too large, which is beneficial to avoiding the overlarge rotation stroke of the driving part 21 and facilitating the operation of a user on one hand, and it can be understood that if the rotation angle of the driving part 21 is too large, the user is difficult to complete; on the other hand, the interference between the driving member 21 and other parts is avoided, and the reliability of the operation of the driving member 21 is ensured. For example, as shown in fig. 7, the first position is located above the second position, and the user presses the free end of the driving member 21 downward to rotate the driving member 21 from the first position to the second position in the counterclockwise direction about the rotation axis L, in which the rotation track of the driving member 21 is an arc.

The rotation angle of the driving member 21 from the first position to the second position may be 10 °, 20 °, 30 °, 40 °, 50 °, 60 °, 70 °, 80 °, 90 °, 100 °, 110 °, or 120 °, and the design of the rotation angle of the driving member 21 from the first position to the second position may be adjusted according to actual needs, which is not limited in the present invention.

In some alternative embodiments of the present invention, referring to fig. 6, the driving assembly 2 further comprises an elastic restoring member 22, and the elastic restoring member 22 is used for driving the driving member 21 to restore to the first position. It will be appreciated that the resilient return member 22 exerts a resilient deformation force on the drive member 21 which is directed towards the first position when the drive member 21 is rotated from the first position to the second position by a user, and that the drive member 21 is returned to the first position by the resilient return member 22 when the user releases the hand, whereby the drive member 21 does not have to be manually returned to the first position when the drive member 21 is operated from the first position to the second position, further facilitating the user operation, and that, compared to conventional manual dispensing devices, and because the liquid suction area 114 and the liquid discharge area 115 of the dispensing pump 1 are located in different areas, the liquid suction at the liquid inlet 116 and the liquid discharge at the liquid outlet 117 of the dispensing pump 1 are synchronized in time when the dispensing device 10 is operating normally, so that the resilient return member 22 is not required, and the user does not need a great force to effect dispensing when pressing the drive assembly 2, the operation comfort of the user is improved. Of course, the present invention is not limited thereto, and the driving assembly 2 may not include the elastic restoring member 22, and after the user drives the driving member 21 to rotate from the first position to the second position, the driving member 21 may be manually rotated to restore the driving member 21 from the second position to the first position.

In some embodiments of the invention, as shown with reference to fig. 6, the resilient return member 22 is connected at one end to the drive member 21 and at the other end to the pump housing 11. For example, as shown in fig. 6, the elastic restoring member 22 is a spring, the pump housing 11 is integrally formed with the storage case 20, and one end of the elastic restoring member 22 is connected to an upper portion of the driving member 21 and the other end is connected to an outer sidewall of the storage case 20. It can be understood that, referring to fig. 6, when the driving member 21 receives the driving force F, the elastic restoring member 22 is deformed in tension, and when the driving force F is removed, the elastic restoring member 22 is deformed again to drive the driving member 21 to restore, which is simple in structure and convenient in operation.

Alternatively, referring to fig. 6, at least a portion of the driving member 21 forms the elastic restoring member 22, for example, at least a portion of the driving member 21 may be made of an elastic material such as plastic or metal spring, and when the driving member 21 is rotated by a force, the elastic restoring member 22 is deformed at the same time, and when the driving force is removed, the elastic restoring member 22 is deformed to drive the driving member 21 to restore. Therefore, the driving piece 21 can reset under the self action, and an elastic resetting piece 22 is not needed to be additionally arranged, so that the number of parts can be reduced, and the installation is convenient.

In some embodiments of the present invention, referring to fig. 6, the pump body 12 comprises two rotatable and mutually engaged sub-pump bodies 121, and it can be understood that, by making the pump body 12 comprise two rotatable and mutually engaged sub-pump bodies 121, the operational reliability of the dispensing pump 1 is improved, and when the dispensing pump 1 does not work, the leakage of the dispensing pump 1 is avoided.

Alternatively, referring to FIG. 12, the pump body 12 is a vane pump 14. It will be appreciated that the impeller pump 14 rotates the liquid at a high speed to transfer mechanical energy to the liquid for the purpose of transporting the liquid. For example, the vane pump 14 may be a centrifugal or axial vane pump.

In some alternative embodiments of the present invention, as shown in fig. 5 and 10, the pump body 12 includes two rotatable and externally engaged sub-pump bodies 121, and the sub-pump bodies 121 are gears (see fig. 5) or screws (see fig. 10). Therefore, the structure is simple, the reliability of the work of the pump body 12 is further improved, and the throwing precision of single throwing is ensured. Of course, the present invention is not limited to this, and the pump body 12 may be replaced by two gear pump bodies that rotate and mesh with each other, for example, the pump body 12 may include an internal gear and an external gear, the external gear is located inside the internal gear and is eccentrically arranged with respect to the internal gear, the driving member 21 of the driving assembly 2 is connected to the external gear, the external gear is driven to rotate by the rotation of the driving member 21, the external gear drives the internal gear to rotate, so as to drive the lotion in the pump housing 11 to flow, so as to generate a negative pressure at the liquid inlet 116, generate a positive pressure at the liquid outlet 117, and the lotion in the liquid suction region 114 flows to the liquid discharge region 115 under the effect of the pressure difference and is discharged through the liquid outlet 117, so as to achieve the dispensing of the lotion.

In some embodiments of the present invention, and with reference to fig. 12, the pump body 12 is a vane pump 14, the pump housing 11 defines a mounting cavity 13 therein having a circular cross-section, the vane pump 14 including: disk 141 and a plurality of blades 142, disk 141 rotationally establishes in installation cavity 13, and disk 141 is eccentric setting relatively installation cavity 13, prescribes a limit to suction and discharge chamber 131 between the periphery wall of disk 141 and the internal perisporium of installation cavity 13, and suction and discharge chamber 131 includes suction region 114 and flowing back region 115, and a plurality of blades 142 set up at the interval in disk 141's circumference, and the one end of each blade 142 links to each other with disk 141 and the other end ends and installation cavity 13's internal perisporium elasticity ends to. For example, as shown in fig. 12, one end of each vane 142 is connected to the disc 141 through a spring element 143, so that the other end of each vane 142 is elastically abutted against the inner peripheral wall of the mounting cavity 13, when the vane pump 14 is driven by the driving assembly 2 to rotate clockwise, the vane 142 drives the liquid in the mounting cavity 13 to rotate, due to the eccentric arrangement of the disc 141, a negative pressure is generated at the liquid inlet 116, which achieves a liquid suction effect, and a positive pressure is generated at the liquid outlet 117, which causes the liquid to be squeezed out at the liquid outlet 117, which achieves a liquid discharge effect.

It can be understood that the control of the dosage of the lotion can be realized by controlling the rotation angle of the driving member 21, and the liquid suction and the liquid discharge of the dispensing pump 1 are synchronous in time, so that the dosage of the dispensing pump 1 is not limited by the volume of the dispensing pump 1, the dosage of the dispensing device 10 can be increased and the dispensing precision of the dispensing device 10 can be ensured, meanwhile, because one end of each blade 142 is connected with the wheel disc 141 and the other end is elastically stopped against the inner peripheral wall of the mounting cavity 13, the reliable liquid feeding and the liquid discharge of the dispensing pump 1 can be ensured, and when the impeller pump 14 stops working, the other end of each blade 142 is elastically stopped against the inner peripheral wall of the mounting cavity 13 to realize the sealing, which is beneficial to avoiding the leakage of the dispensing device 10.

In some embodiments of the present invention, referring to fig. 12, the dispensing device 10 further comprises a cylindrical mounting seat 15, the mounting seat 15 is disposed in the pump housing 11 and fixed relative to the pump housing 11, a mounting cavity 13 is formed in the mounting seat 15, and the mounting cavity 13 is eccentrically disposed relative to the mounting seat 15. It can be understood that the installation seat 15 and the pump shell 11 are arranged in a split manner, so that the respective processing difficulty of the installation seat 15 and the pump shell 11 is reduced, and the mold opening cost is reduced.

Of course, the invention is not limited thereto, but the mounting seat 15 and the pump housing 11 may also be one piece. It can be understood that the structure and the performance stability of the mounting seat 15 and the pump case 11 can be guaranteed by the integrally formed structure, the integrally formed structure is convenient to form and simple to manufacture, redundant assembling parts and connecting procedures are omitted, the assembling efficiency of the mounting seat 15 and the pump case 11 is greatly improved, the reliability of connection of the mounting seat 15 and the pump case 11 is guaranteed, and moreover, the integrally formed structure is high in overall strength and stability, more convenient to assemble and longer in service life.

Alternatively, in some examples, as shown in fig. 12, the central axis of the mount 15 may coincide with the central axis of the wheel disc 141, thereby facilitating machining and reducing costs.
