Description

Technical Field

[0001] This invention relates to the field of washing device technology, and in particular to a dispensing device and washing equipment. Background Technology

[0002] In existing push-button dispensing devices, the amount of detergent dispensed per press is very limited. For applications requiring higher detergent volumes, it is necessary to increase the amount dispensed per press. However, in practice, increasing the amount of detergent dispensed per press requires greater pressing force, which increases the difficulty of operation for users and results in a poor user experience. Summary of the Invention

[0006] According to the dispensing device of the present invention, by configuring the transmission mechanism to include multiple linkages, power can be transmitted to the drive rod, which can drive the dispensing pump to dispense the treatment agent. Since multiple linkages can amplify the stroke of the user pressing the drive button, the user can move the drive rod a large distance by lightly pressing the drive button, thereby meeting the application scenarios with high treatment agent usage and reducing the difficulty of pressing. In addition, the stroke of the drive rod can be set according to the space requirements and the amount of treatment agent dispensed by pressing the drive button once, thereby reasonably designing the length and setting position of the multiple linkages to meet the diverse needs of users.

[0011] In some embodiments, the plurality of links further includes: a first link; a second link, one end of the second link being hinged to one end of the first link, and the other end of the second link being hinged to one end of the drive rod.

[0012] In some examples, one end of the second link is hinged to one end of the first link via a first connecting shaft, which is provided with a roller that engages with the drive button.

[0013] In some specific examples, the drive button is movable between a first position and a second position, and the sum of the straight-line distance between the two ends of the first link and the two ends of the second link is greater than twice the travel distance of the drive button.

[0014] In some examples, the transmission mechanism further includes a fixed seat, which is hinged to the other end of the first connecting rod via a second connecting shaft; the fixed seat is located on the dispensing pump.

[0015] In some specific examples, the orthographic projection of the roller onto the plane containing the axes of the first connecting shaft and the second connecting shaft lies between the first connecting shaft and the second connecting shaft.

[0034] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The following is for reference. Figures 1-5The dispensing device 100 according to an embodiment of the present invention is described.

[0036] like Figures 1-4 As shown, the dispensing device 100 according to an embodiment of the present invention includes a drive button (not shown), a dispensing pump 20, and a transmission mechanism 30.

[0037] The dispensing pump 20 is used to dispense the treatment agent when the drive button is pressed. The treatment agent can be detergent, fabric softener, disinfectant, etc. The transmission mechanism 30 is located between the drive button and the dispensing pump 20, that is, the drive button can be connected to the dispensing pump 20 through the transmission mechanism 30.

[0038] The transmission mechanism 30 includes multiple connecting rods that are hinged together, thus forming a linkage mechanism. One of the multiple connecting rods is a drive rod 32, which is in transmission cooperation with the dispensing pump 20.

[0039] According to the dispensing device 100 of the present invention, the transmission mechanism 30 is configured to include multiple linkages. Power can be transmitted to the drive rod 32 by the multiple linkages. The drive rod 32 can drive the dispensing pump 20 to dispense the treatment agent. Since the multiple linkages can amplify the stroke of the user pressing the drive button, the user can move the drive rod a large distance by lightly pressing the drive button, thereby meeting the application scenarios with high treatment agent usage and reducing the difficulty of pressing. In addition, the stroke of the drive rod 32 can be set according to the space and the amount of treatment agent dispensed by pressing the drive button once, so that the structure, size, and setting position of the multiple linkages can be reasonably designed to meet the diverse needs of users.

[0040] like Figure 3 As shown, according to some embodiments of the present invention, the drive rod 32 is linearly movable relative to the dispensing pump 20. By configuring the transmission mechanism 30 as multiple linkages, the movement trend of the drive button can be transmitted to the drive rod 32, thereby enabling the drive rod 32 to drive the dispensing pump 20, resulting in a simple structure.

[0041] The movement direction of the drive button and the drive lever 32 can be the same; for example, both the drive button and the drive lever 32 can move horizontally or vertically. Alternatively, the movement direction of the drive button and the drive lever 32 can be different. For example, the drive button can move diagonally downwards, and the drive lever 32 can move horizontally. Of course, the drive button can also be set to swing within a preset angle range.

[0042] It should be noted that since the multiple links in the transmission mechanism 30 are hinged, the transmission mechanism 30 can form a linkage mechanism. The stroke of any link in the linkage mechanism is fixed. Even if the drive rod 32 has a fixed stroke, the quantitative dispensing of the dispensing pump 20 can be realized.

[0043] like Figure 2 and Figure 3 As shown, in some embodiments, the drive rod 32 is provided with a rack 321, and the transmission mechanism 30 further includes a gear 35, which cooperates with the dispensing pump 20 and meshes with the rack 321. The rack 321 can extend along the moving direction of the drive rod 32.

[0044] When the drive button is pressed, the transmission mechanism 30 operates synchronously, causing the rack 321 to move synchronously. Since the rack 321 meshes with the gear 35, the rack 321 can drive the gear 35 to rotate, thereby enabling the dispensing pump 20 to operate under the drive of the gear 35, realizing the dispensing of the treatment agent. When the drive button is released, the dispensing pump 20 stops operating. The structure is simple and the operation is easy.

[0045] like Figure 3 As shown, in some embodiments, an elastic element 40 is provided between the drive rod 32 and the dispensing pump 20. The elastic element 40 is used to drive the drive rod 32 to move so as to reset the drive button.

[0046] Therefore, by setting the elastic element 40, not only can the drive rod 32 be automatically reset by the elastic element 40, thereby resetting the drive button and facilitating subsequent control, but the dispensing pump 20 can also be controlled to stop dispensing the treatment agent, so as to realize the quantitative dispensing of the dispensing pump 20.

[0047] like Figure 1 and Figure 3 As shown, in some examples, the outer surface of the dispensing pump 20 is provided with a positioning plate 2121, the drive rod 32 is provided with a positioning groove 322, one end of the elastic member 40 is inserted into the positioning groove 322, and the other end of the elastic member 40 abuts against the positioning plate 2121. By setting the positioning groove 322 and the positioning plate 2121, the elastic member 40 can be stably positioned between the drive rod 32 and the dispensing pump 20, thereby enabling the drive rod 32 to achieve stable reset, and thus enabling the drive button to achieve stable reset.

[0048] Specifically, the elastic element 40 forms a spring, and one end of the drive rod 32 is provided with a positioning groove 322 extending along its length direction. One end of the spring is inserted into the positioning groove 322, so that the central axis of the spring is parallel to the length direction of the drive rod 32, ensuring that the drive rod 32 can be reset normally.

[0049] The positioning plate 2121 is provided with two oppositely arranged limiting plates 2122. The two limiting plates 2122 can limit the elastic element 40 and prevent the elastic element 40 from disengaging from the positioning plate 2121.

[0050] like Figures 1-3 As shown, in some embodiments, the multiple links also include a first link 33 and a second link 34. One end of the second link 34 is hinged to one end of the first link 33, and the other end of the second link 34 is hinged to one end of the drive rod 32. The structure is simple, easy to process and manufacture, and has a low cost.

[0051] In some examples, one end of the second link 34 is hinged to one end of the first link 33 via a first connecting shaft 36. This design is simple, easy to manufacture, convenient to assemble and disassemble, and has low cost. The first connecting shaft 36 is equipped with a roller 39, which engages with a drive button.

[0052] Therefore, by setting up the roller 39, since the size of the roller 39 is larger than that of the first connecting shaft 36, it can easily cooperate with the drive button to drive the dispensing pump 20 to dispense the treatment agent normally. In addition, the roller 39 can replace the sliding friction between the first connecting shaft 36 and the drive button with the rolling friction between the roller 39 and the drive button, which further reduces the driving difficulty and ensures the smoothness of the pressing process.

[0053] Specifically, when the drive button is pressed, it first contacts the roller 39, causing the roller 39 to rotate. The roller 39 then moves under external force, for example, diagonally downwards or horizontally. This causes the first connecting rod 33 to rotate, and the second connecting rod 34 moves under the influence of the first connecting rod 33. Since the drive rod 32 is connected to the second connecting rod 34, and the rack 321 on the drive rod 32 meshes with the gear 35 on the dispensing pump 20, the second connecting rod 34 can drive the drive rod 32 to move. This, in turn, drives the dispensing pump 20 to start operating via the gear 35 to dispense the treatment agent. During this process, the elastic element 40 is compressed. When the drive button is pressed again, the drive rod 32 moves back to its initial position under the action of the elastic element 40, thus stopping the dispensing pump 20.

[0054] In some specific examples, the drive button is movable between a first position and a second position, and the sum of the straight-line distance between the two ends of the first link 33 and the two ends of the second link 34 is greater than twice the travel distance of the drive button.

[0055] In other words, the sum of the straight-line distance L1 between the two hinged ends of the first link 33 and the straight-line distance L2 between the two hinged ends of the second link 34 is greater than twice the distance between the first and second positions of the drive button. This increases the travel distance of the user pressing the drive button, allowing the user to move the drive button a small distance with a light press, thus enabling the drive rod 32 to move a large distance. This meets the needs of application scenarios with high treatment agent usage, reduces the difficulty of operation for users, and improves the user experience.

[0056] like Figure 1 and Figure 3 As shown, in some examples, the transmission mechanism 30 also includes a fixed base 31, which is hinged to the other end of the first connecting rod 33 via a second connecting shaft 37. By providing the fixed base 31, the installation of the first connecting rod 33 is facilitated, and the stroke requirements of the drive rod 32 can be met, thereby enabling the dispensing pump 20 to achieve quantitative dispensing.

[0057] In some specific examples, the mounting base 31 is provided on the dispensing pump 20. For example, the mounting base 31 can be installed on the housing 21 of the dispensing pump 20 by means of fasteners or clips; or the mounting base 31 and the housing 21 of the dispensing pump 20 can be connected by welding or bonding; or the mounting base 31 and a part of the housing 21 of the dispensing pump 20 can be integrally formed.

[0058] In some specific examples, the housing 21 of the dispensing pump 20 includes a housing 211 and a cover 212, the housing 211 defining a receiving cavity 201 having an opening, and the cover 212 disposed on the housing 211 for closing the opening.

[0059] Reference Figure 3 The cover 212 has a mating groove 2123 on the side facing the housing 211, and the housing 211 is inserted into the mating groove 2123. The housing 211 has an inlet 2101 and an outlet 2102. The inlet 2101 can communicate with the storage box of the treatment agent, and the outlet 2102 can communicate with the dispensing chamber. When the dispensing pump 20 is working, the treatment agent can be dispensed into the dispensing chamber.

[0060] The fixing seat 31 is located on the side wall of the housing 211. For example, the fixing seat 31 and the housing 211 can be integrally formed. The positioning plate 2121 is located on the cover 212. The drive rod 32 and the second connecting rod 34 are located above the cover 212. The first connecting rod 33 can be formed into a bent rod that bends away from the dispensing pump 20, so that the first connecting rod 33 extends from the side wall of the housing 211 toward the cover 212, which facilitates the connection between the first connecting rod 33 and the second connecting rod 34, thereby meeting the functional requirements. Furthermore, by setting the connecting rod 33 as a bent rod, the first connecting rod 33 can avoid the dispensing pump 20, thus preventing the first connecting rod 33 from interfering with the dispensing pump 20 when rotating.

[0061] In some specific examples, the second link 34 and the drive rod 32 are hinged together by the third connecting shaft 38. The structure is simple, easy to process and manufacture, and easy to assemble and disassemble with low cost.

[0062] The central axes of the first connecting shaft 36, the second connecting shaft 37, and the third connecting shaft 38 are parallel to each other, ensuring that the transmission mechanism 30 achieves precise transmission.

[0063] In some specific examples, the orthographic projection of the roller 39 in the plane containing the axis of the first connecting shaft 36 and the axis of the second connecting shaft 37 is located between the first connecting shaft 36 and the second connecting shaft 37. This arrangement not only prevents the first link 33 and the second link 34 from locking up, and the second link 34 and the drive rod 32 from locking up, thus ensuring normal dispensing of the treatment agent, but also achieves the purpose of saving effort and reducing the difficulty of pressing.

[0064] It should be noted that, in order to reduce the difficulty of pressing and avoid self-locking between multiple links, the second connecting shaft 37 and the third connecting shaft 38 are as close as possible in the vertical direction, and the roller 39 is as far away from the second connecting shaft 37 as possible. The specific design can be reasonably made according to the placement space of the dispensing device 100 and other conditions.

[0065] like Figure 5 As shown, according to a further embodiment of the present invention, the dispensing device 100 further includes a nozzle body 50, the nozzle body 50 having a dispensing cavity 513 and a first dispensing hole 5145, the first dispensing hole 5145 communicating with the dispensing cavity 513, and the outlet of the dispensing pump 20 communicating with the first dispensing hole 5145.

[0066] Specifically, the nozzle body 50 has a first flow channel, and the first dispensing hole 5145 connects the first flow channel and the dispensing cavity 513. The first flow channel can deliver the treatment agent inside it to the dispensing cavity 513.

[0067] The nozzle body 50 has an upward-facing mounting recess 515 at its top. A dispensing pump 20 is located in the mounting recess 515 and above the first flow channel. The first flow channel is connected to the dispensing pump 20. When the dispensing pump 20 is working, it can dispense the treatment agent from the first flow channel into the dispensing chamber 513. In other words, the dispensing pump 20 can control the opening and closing of the first flow channel. When the dispensing pump 20 is pressed once, a quantitative dispensing of liquid can be achieved, thus realizing an intermittent dispensing pattern of the treatment agent. When the dispensing pump 20 is not working, it can disconnect the first flow channel, preventing the dispensing of treatment agent.

[0068] In some embodiments, the nozzle body 50 further includes a second dispensing hole and a second flow channel. The second dispensing hole connects the second flow channel and the dispensing chamber 513. The second flow channel can deliver the treatment agent inside to the dispensing chamber 513. The treatment agent in the second flow channel is suitable for natural dispensing under gravity. That is, there is no need to set up a separate power component to dispense the treatment agent in the second flow channel into the dispensing chamber 513. Instead, the treatment agent relies on gravity to flow naturally into the dispensing chamber 513, thereby achieving a continuous liquid dispensing of the treatment agent.

[0069] In some embodiments, the first channel and the second channel are connected. By setting the first channel and the second channel, the dosage of the treatment agent in a single delivery can be increased. When one channel fails, the other channel can be used for delivery without affecting the normal use of the delivery device 100 and ensuring the user experience.

[0070] like Figure 5 As shown, in some embodiments, the nozzle body 50 has a liquid inlet 521 that communicates with the second flow channel. A storage box is provided on the top of the nozzle body 50, and the liquid outlet of the storage box communicates with the liquid inlet 521. Specifically, the treatment agent in the storage box can be discharged from the liquid outlet and then enter the second and first flow channels through the liquid inlet 521, thereby facilitating various liquid discharge methods and enriching the liquid discharge options to meet the user's needs in different scenarios.

[0071] In some embodiments, the nozzle body 50 includes a nozzle body 51 and a cover plate 52. An inlet hole 521 is provided on the cover plate 52, and a second dispensing hole is provided on the nozzle body 51. The nozzle body 51 and the cover plate 52 are connected to define a second flow channel. The nozzle body 51 and the cover plate 52 can be connected by snap-fit, fasteners, welding, or bonding to ensure the reliability of the connection between the two.

[0072] The nozzle body 51 has a flow guide groove on its upper surface. The top of the flow guide groove is open. A cover plate 52 is provided on the nozzle body 51. The cover plate 52 can close the top opening of the flow guide groove. The cover plate 52 and the flow guide groove define a second flow channel. The structure is simple and easy to form.

[0073] like Figure 5 As shown, in some examples, the cover plate 52 is provided with an annular rib 522, which protrudes from the surface of the cover plate 52 and surrounds the liquid inlet hole 521. The storage box is provided with a removable sealing plug, which can cooperate with the annular rib 522.

[0074] Specifically, the sealing plug is located inside the storage box, and the cover plate 52 is located outside the storage box. The storage box and the cover plate 52 can be connected by the cooperation of the sealing plug and the annular rib 522, thereby fixing the storage box to the nozzle body 50. The sealing plug and the annular rib 522 can be arranged concentrically, which is beneficial to the reliability and sealing of the assembly.

[0075] In some specific examples, the sealing plug can form a one-way liquid outlet channel. When the storage box is separated from the nozzle body 50, the sealing plug is in a blocked state, and the liquid in the storage box will not flow out from the location of the sealing plug. When the storage box and the nozzle body 50 are in place, the protrusion in the annular rib 522 stops the sealing plug, causing the sealing plug to switch to a conductive state, thereby ensuring smooth liquid outlet.

[0076] In some embodiments, the top of the nozzle body 50 is provided with an outer trim component, which defines a mounting channel, and the drive button slides in the mounting channel. By providing a mounting channel in the outer trim component, the mounting channel can be used to position and guide the movement of the drive button.

[0077] Specifically, the drive button is movable between a first position and a second position. The drive button in the first and second positions can be limited by the outer trim component to prevent it from dislodging from the mounting channel. The first position is located outside the second position in the extending direction of the mounting channel. In the initial state, the drive button is in the first position. The user presses the drive button, causing it to move inward along the mounting channel, thereby controlling the dispensing pump 20.

[0078] like Figure 5 As shown, in some embodiments, the dispensing device 100 further includes a drawer 60 that defines a dissolving chamber 61. The drawer 60 is slidably disposed within the dispensing chamber 513 between an open position and a closed position. When the drawer 60 is in the closed position, the drawer 60 is spaced apart from the bottom wall of the dispensing chamber 513 to define a liquid spray channel.

[0079] The treatment agent flowing out from the first and second dispensing holes enters the dissolving chamber 61. Water enters the dissolving chamber 61 and mixes thoroughly with the treatment agent. Then, it enters the dispensing chamber 513 through the outlet 62 of the dissolving chamber 61 and is finally discharged from multiple through holes on the bottom wall of the dispensing chamber 513 or from the spray channel between the drawer 60 and the bottom wall of the dispensing chamber 513, thereby improving the washing effect of the washing equipment.

[0080] In some embodiments, the two oppositely arranged sidewalls of the drawer 60 each have a guide rail 631, and the two oppositely arranged sidewalls of the dispensing cavity 513 each have a guide groove. The two guide rails 631 and the two guide grooves are slidably engaged in a one-to-one correspondence, allowing the drawer 60 to slide along the extension direction of the guide grooves, ensuring that the drawer 60 can open and close smoothly and stably. Furthermore, the guide grooves provided on the sidewalls of the dispensing cavity 513 can support the guide rails 631 of the drawer 60, so that the drawer 60 is stably installed in the dispensing cavity 513.

[0081] like Figure 5 As shown, in some embodiments, the dispensing device 100 further includes a water-dividing plate 70, which has multiple water outlet holes 701. The water-dividing plate 70 is located inside the dispensing cavity 513 and above the drawer 60. The water-dividing plate 70 can divert the water flow before it enters the dissolving cavity 61, ensuring that the water flows into the dissolving cavity 61 evenly. The water-dividing plate 70 can be connected to the top wall of the dispensing cavity 513 using multiple fasteners to ensure the reliable installation of the water-dividing plate 70.

[0082] Specifically, the water distribution plate 70 and the top wall of the dispensing chamber 513 define a water-containing chamber, which buffers the water flow, slows down the flow rate, and allows the water to flow evenly into the dispensing chamber 513, thereby making the mixing of the water flow and the treatment agent more uniform.

[0083] The water distribution plate 70 has a clearance hole 703 for avoiding the first injection hole 5145 and the second injection hole. That is, the clearance hole 703 can avoid the first injection hole 5145 and the second injection hole, ensuring that the treatment agent can directly enter the injection chamber 513 and avoid the treatment agent being injected into the water holding chamber.

[0084] The following describes a washing apparatus according to an embodiment of the present invention.
