Description

Technical Field

[0001] This invention belongs to the field of clothing cleaning technology, and more specifically, relates to an additive dispensing device. Background Technology

[0002] The laundry detergent dispenser is a frequently used household appliance. It includes an additive dispensing device, which primarily consists of a water tank connected to the dispenser's water inlet and a dispenser box housed within the water tank. The dispenser box is typically designed to be pull-out, allowing users to remove it and add detergent, fabric softener, and / or disinfectant. A thrust mechanism is usually installed on the top or side walls of the dispenser box. After the dispenser box is pulled out a certain distance, the thrust mechanism engages with the internal structure of the water tank, limiting its movement and preventing it from falling out. The thrust mechanism is usually a sheet-like structure fixed to the rear of the dispenser box and suspended at the front. Pressing the front of the thrust mechanism compresses it inwards, dislocating the engagement mechanism within the water tank and allowing the dispenser box to be completely removed.

[0003] However, the above solution has the following problems: In daily use, when disassembling the dispenser box, users need to hold the front end of the dispenser box or the handle installed on the front of the dispenser with one hand, and press the front end of the thrust structure with the other hand. That is, it requires two hands to disassemble the dispenser box. It is not possible or very difficult to disassemble the dispenser box with only one hand, which lacks convenience.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an additive dispensing device. By placing the pull unit compressed by the limiting unit of the control stop structure on the front side of the dispenser box, the user can operate the pull unit located on the front side of the dispenser box while holding the front side of the dispenser box with one hand, thereby solving the problem that the user cannot disassemble the dispenser box with one hand.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: an additive dispensing device, comprising: a water box, inside which is a dispenser box that can be pulled out and pushed back from the front; a thrust-stopping structure disposed on the dispenser box; the thrust-stopping structure includes at least a limiting unit, which at least partially protrudes from the outer wall of the dispenser box, so that when the dispenser box is pulled out to a first position, the limiting unit abuts against the water box and prevents the dispenser box from detaching from the water box; the front side of the dispenser box is provided with a hand-receiving cavity into which a hand can be inserted, and the thrust-stopping structure also includes a pulling unit disposed in the hand-receiving cavity, the pulling unit being connected to the limiting unit through a connecting unit, the pulling unit driving the limiting unit to move into the dispenser box to a compression position intersecting with the water box under the action of external force, the limiting unit in the compression position no longer interferes with the outward pulling of the dispenser box and prevents the other water boxes from detaching.

[0007] Furthermore, a handle is connected to the front of the dispenser box. The handle is hollow inside to form a hand-receiving cavity, and a connecting port is provided on the handle for the hand to be inserted into the receiving cavity.

[0008] Furthermore, a recessed groove is provided on the rear side of the handle, which is fastened to the front side wall of the dispenser box to form a hand receiving cavity.

[0009] Preferably, the connection port is located on the front surface of the handle.

[0010] Furthermore, a baffle structure is provided on the handle, which can be opened and closed to block the communication port;

[0011] Preferably, the baffle structure is located on the rear side of the handle;

[0012] In a further preferred embodiment, the baffle structure is hinged to the rear side of the handle.

[0013] Furthermore, the limiting unit is located on one side edge near the communication port, and the baffle structure is hinged to the rear surface of the handle on the opposite side of the communication port.

[0014] Furthermore, the pulling unit has a sheet-like structure, and the pulling unit has a ring hole along the vertical direction for fingers to insert.

[0015] Furthermore, a recessed mounting groove is provided on one side wall of the distributor box, and the limiting unit of the thrust structure is located in the mounting groove. The limiting unit is spaced apart from the bottom of the mounting groove, and the bottom of the limiting unit is connected to the connecting unit.

[0016] Furthermore, the front of the mounting slot is provided with a connecting channel that communicates with the hand receiving cavity, and the connecting unit is movably disposed within the connecting channel.

[0017] Furthermore, the connecting unit includes a bent portion extending forward from the bottom of the limiting unit; and connecting portions at both ends connected to the extended ends of the bent portion and the pulling unit, respectively.

[0018] Furthermore, a baffle is provided in the mounting groove, and the bent part is located in the gap between the baffle and the bottom of the mounting groove; the baffle abuts against the upper surface of the bent part.

[0019] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: by setting the pulling unit of the limiting unit of the control stop structure compressed on the front side of the dispenser box, the user can operate the pulling unit located on the front side of the dispenser box at the same time while holding the front side of the dispenser box with one hand, so that the user can disassemble the dispenser box with only one hand, which brings convenience to the user.

[0044] In another embodiment of the present invention, the baffle structure 320 is disposed on the front side of the handle portion 3. The baffle structure 320 has a protrusion 322 disposed in the protrusion of the communication port 310. The outer periphery of the protrusion 322 is fitted to fit the shape of the peripheral wall of the communication port 310. The baffle structure 320 is fastened to the outside of the handle portion 3 by friction with the communication port 310.

[0045] In another embodiment of the present invention, the rear surface of the baffle structure 320 is provided with a rearwardly extending claw, and the front surface of the handle portion 3 is provided with a corresponding engaging hole; by passing the extended end of the claw through the corresponding engaging hole and abutting against the rear surface of the handle portion 3, the baffle structure 320 is fixed on the handle portion 3.

A hinge hole is provided on the hinge plate 330, and each protrusion is inserted into the corresponding hinge hole.

[0053] In the embodiments of the present invention, each hinge plate 330 is provided with a reinforcing plate 331 extending away from the corresponding hinge portion 321 at its upper and lower ends, and each hinge plate 330 and the corresponding reinforcing plate 331 form a U-shaped structure to enhance the structural strength of the hinge plate 330, prevent the hinge plate 330 from deforming in the left and right direction, and improve the stability of the hinge between the baffle structure 320 and the handle portion 3.

[0054] In an embodiment of the present invention, the hinge plate 330 is provided with a protrusion 322 protruding into the communication port 310, and the outer periphery of the protrusion 322 is fitted to the periphery edge of the communication port 310.

[0055] In an embodiment of the present invention, the front surface of the protrusion 322 of the baffle structure 320 is flush with the front surface of the handle portion 3.

[0056] In an embodiment of the present invention, the rear outer periphery of the protrusion 322 is connected to an outwardly extending support leg 323, and the front surface of the support leg 323 and the outer periphery of the protrusion 322 form an L-shaped corner; the L-shaped corner further seals the communication port 310, preventing dust from entering the hand receiving cavity 301 through the gap between the outer periphery of the protrusion 322 and the peripheral wall of the communication port 310.

[0057] In an embodiment of the present invention, a torsion spring is provided between the baffle structure 320 and the handle portion 3; when the baffle structure 320 is flipped by hand, the torsion spring is compressed; when the hand leaves the baffle structure 320, the torsion spring pushes the baffle structure 320 to reset, so that the baffle structure 320 is re-fastened to the communication port 310.

[0058] In an embodiment of the present invention, the protrusion 322 is connected to the hinge 321 via the support leg 323 to form a baffle structure 320.

[0059] In an embodiment of the present invention, the pulling unit 230 is a sheet-like structure, and the pulling unit 230 has a finger ring hole 231 for inserting fingers in the vertical direction; after the user inserts his palm upward into the receiving cavity, he pulls the pulling unit 230 by inserting his fingers into the finger ring hole 231, thereby driving the pulling unit 230.

[0060] In another embodiment of the present invention, the lower surface of the drive structure is provided with an upwardly recessed portion; the user drives the pulling unit 230 by inserting a finger into the recess.

[0061] In one embodiment of the present invention, the drive structure is provided with an uneven surface; the user drives the drive structure by the friction between the finger and the surface of the drive structure.

[0062] In an embodiment of the present invention, a recessed mounting groove 110 is provided on one side wall of the dispenser box 1. The limiting unit 210 of the thrust structure 2 is disposed in the mounting groove 110, and the limiting unit 210 is spaced apart from the bottom of the mounting groove 110. The bottom of the limiting unit 210 is connected to the connecting unit 240. By providing the mounting groove 110, space is provided for installing the thrust structure 2, while also providing space for the limiting unit 210 to compress.

[0063] In an embodiment of the present invention, the mounting groove 110 is provided on the top of the dispenser box 1; specifically, the top of the dispenser box 1 is recessed inward to form the mounting groove 110.

[0064] In an embodiment of the present invention, the limiting unit 210 includes a thrust key 211. One end of the thrust key 211 is connected to the mounting groove 110 through the fixing unit 220 of the thrust structure 2, and the opposite extension end is spaced apart from the bottom of the mounting groove 110. The connecting unit 240 is connected to the bottom of the extension end of the thrust key 211.

[0065] In an embodiment of the present invention, the thrust key 211 is flush with the opening of the mounting groove 110.

[0066] In an embodiment of the present invention, the thrust key 211 is a sheet-like structure; furthermore, the sheet-like thrust key 211 is arranged parallel to the bottom of the mounting groove 110.

[0067] In embodiments of the present invention, the thrust key 211 is a strip-shaped structure, and the strip-shaped thrust key 211 extends along the front-back direction; preferably, the mounting groove 110 is a strip-shaped groove extending along the front-back direction, and the thrust key 211 blocks the opening of the mounting groove 110.

[0068] In an embodiment of the present invention, the fixing unit 220 is connected to the rear end or the front end of the strip-shaped thrust key 211; the front end or the rear end of the strip-shaped thrust key 211 is spaced apart from the bottom of the mounting groove 110, and the bottom of the front end or the rear end is connected to the connecting unit 240; the thrust key 211 is made to form a rocker with the fixing unit 220 as the fulcrum, and the compression deformation of the limiting unit 210 is achieved by bending the extended end into the mounting groove 110.

[0069] In an embodiment of the present invention, the limiting unit 210 further includes a protrusion 212 on the thrust key 211 that protrudes in a direction away from the mounting groove 110. When the dispenser box 1 is pulled out to the first position, the protrusion 212 abuts against the water box.

[0070] In an embodiment of the present invention, the water box is provided with an installation cavity with an opening on the front side, and a stop structure protruding downward is provided on the top of the installation cavity. When the dispenser box 1 is pulled out to the first position, the stop structure abuts against the thrust structure 2. Specifically, the rear side of the stop structure abuts against the front side of the protrusion 212 of the thrust structure 2.

[0071] In an embodiment of the present invention, the protrusion 212 is provided with a vertical front surface and an inclined surface that slopes backward and downward from the top of the front surface. The front surface of the protrusion 212 abuts against the water box and limits the position of the dispenser box 1. In addition, when the disassembled dispenser box 1 is reinstalled into the water box, the inclined surface of the protrusion 212 cooperates with the abutment position of the water box to cause the push button 211 to automatically deform downward, so that the dispenser box 1 is reinstalled inside the water box.

[0072] In an embodiment of the present invention, the protrusion 212 is disposed on the top of the thrust key 211; more preferably, the protrusion 212 is disposed directly above the position where the thrust key 211 is connected to the connecting unit 240.

[0073] In an embodiment of the present invention, the extension end of the thrust key 211 is connected to a pressing part 213, which is located inside the mounting groove 110. The pressing part 213 is spaced apart from the bottom of the mounting groove 110. The connection position between the connecting unit 240 and the thrust key 211 is located between the pressing part 213 and the fixing unit 220. By pressing the pressing part 213, the extension end of the thrust key 211 can also be driven to deform downward. In the event of damage to the pulling unit 230 or the connecting unit 240, the pressing part 213 can compress and deform the limiting unit 210 into the mounting groove 110 to disassemble the distributor box 1, thus facilitating the user to replace the thrust structure 2.

[0074] In an embodiment of the present invention, the front of the mounting groove 110 is provided with a communication channel 120 that communicates with the hand receiving cavity 301, and the connecting unit 240 is movably disposed in the communication channel 120.

[0075] In an embodiment of the present invention, the connecting unit 240 is a strip-shaped structure. One end of the strip-shaped connecting unit 240 is connected to the bottom of the limiting unit 210, and the other end extends through the connecting channel 120 into the hand receiving cavity 301 and is connected to the pulling unit 230.

[0076] With the above settings, by driving the pulling unit 230 to move away from the distributor box 1, the connecting unit 240 is pulled to apply a downward force to the limiting unit 210, causing the limiting unit 210 to deform into the mounting groove 110, thereby releasing the limiting effect of the limiting unit 210 on the distributor box 1.

[0077] In an embodiment of the present invention, the rear end of the thrust key 211 of the limiting unit 210 is connected to the mounting groove 110 via the fixing unit 220, and the opposite front end is connected to the connecting unit 240. Since the connecting unit 240 applies a downward and forward inclined force to the limiting unit 210, it can be decomposed into a downward pulling force and a horizontal forward pulling force. The downward pulling force causes the thrust key 211 to bend downward, while the forward pulling force is a force that causes the thrust key 211 to extend outward in the horizontal direction. Compared with the force that causes the thrust key 211 to compress inward in the horizontal direction, it is less likely to cause the thrust key 211 to deform, thereby improving the service life of the thrust structure 2.

[0078] In an embodiment of the present invention, the cross-section of the connecting channel 120 is rectangular, and the corresponding connecting unit 240 is a rectangular strip structure with a matching shape; preferably, the cross-sectional size of the connecting unit 240 is equal to or slightly smaller than the cross-sectional size of the connecting channel 120; through the shape matching between the connecting channel and the connecting unit 240, the circumferential direction of the connecting structure is limited to prevent the connecting structure from rotating around its own axis and affecting the user's use.

[0079] In an embodiment of the present invention, the pulling unit 230 is a sheet-like structure with the same cross-sectional dimensions as the connecting unit 240.

[0080] In an embodiment of the present invention, the connecting unit 240 includes a bent portion 241 extending forward from the bottom of the limiting unit 210; and a connecting portion 242 connected at both ends to the extended end of the bent portion 241 and the pulling unit 230, respectively; the bent portion 241 is located in the mounting groove 110, and the connecting portion 242 extends out of the mounting groove 110 through the communicating channel 120.

[0081] In an embodiment of the present invention, the bottom of the front side wall of the mounting groove 110 is connected to the communication channel 120.

[0082] In an embodiment of the present invention, the connecting channel 120 extends horizontally forward; the extended end of the bent portion 241 is horizontally forward corresponding to the connecting portion 242.

[0083] In an embodiment of the present invention, the bottom of the horizontally extending connecting channel 120 is flush with the bottom of the mounting groove 110.

[0084] In an embodiment of the present invention, the extended end of the bent portion 241 is in contact with the bottom of the mounting groove 110; the bent portion 241 has the function of pulling the limiting unit 210, and also has the function of supporting the limiting unit 210. After the pulling unit 230 is reset, the bent portion 241 springs back to its original shape, the extended end of the bent portion 241 abuts against the bottom of the mounting groove 110, and the opposite connecting end pushes the limiting unit 210 to reset and supports the limiting unit 210, so as to prevent the suspended extended end of the limiting unit 210 from bending downward and deforming, which would affect the stability of the limiting of the distributor box 1.

[0085] In embodiments of the present invention, each unit of the thrust structure 2 is integrated.

[0086] In an embodiment of the present invention, a baffle 111 is provided in the mounting groove 110, and a bent portion 241 is disposed in the gap between the baffle 111 and the bottom of the mounting groove 110; the baffle 111 abuts against the upper surface of the bent portion 241; by setting the baffle 111, the connecting unit 240 is limited to prevent the limiting unit 210 from shifting; and by blocking the previous displacement of the bent portion 241 by the baffle 111, while ensuring that the tension remains unchanged, the force tilted forward from top to bottom is corrected into a downward tension or the tilt angle is reduced, thereby increasing the magnitude of the vertical downward component of the tension, so that the user can more easily drive the limiting unit 210 to deform downward.

[0087] In an embodiment of the present invention, the fixing unit 220 is a claw structure, and a locking post is provided in the mounting groove 110. The two ends of the locking post are respectively connected to the two side walls of the mounting groove 110, and the fixing unit 220 is detachably locked onto the locking post.

[0088] In an embodiment of the present invention, the locking post is disposed at the rear of the mounting groove 110 and is spaced apart from the groove wall at the rear end; the fixing unit 220 includes two locking claws disposed at the front and rear, which respectively engage with the rear and front sides of the locking post, thereby realizing the engaging connection between the fixing unit 220 and the locking post.

[0089] In an embodiment of the present invention, the baffle 111 is a columnar structure with both ends connected to the groove walls on the left and right sides of the mounting groove 110.
