It should be understood that first receiving recess 101 is cylindrical and first liquid inlet 102 is connected to first receiving recess 101, allowing laundry detergent in the laundry detergent bottle to enter first receiving recess 101 through first liquid inlet 102.

[0037] The first cover tube 11 is arranged in the first receiving groove 101 of the liquid storage 10. Specifically, a first annular ring 103 in a circular shape is provided at the top of the liquid storage 10, wherein a second annular ring 104 in a circular shape is provided on the first annular ring 103, and a third annular ring 110 in a circular shape and clamped on the second annular ring 104 is provided at the top of the first cover tube 11.

[0038] Preferably, the outer diameter of the first annular ring 103 is larger than the outer diameter of the second annular ring 104, and the length of the first cover tube 11 is smaller than the depth of the first receiving groove 101, wherein the outer diameter of the first cover tube 11 is equal to the aperture of the first receiving groove 101, and a first sealing ring is provided between the outer wall of the top end of the first cover tube 11 and the inner wall of the first receiving groove 101 of the liquid storage 10.

[0039] In this embodiment, a first receiving hole 111 is formed through the first cover tube 11, wherein a separator 112 is provided at the bottom end of the first receiving hole 111 of the first cover tube 11. The separator 112 divides the bottom end of the first receiving hole 111 of the first cover tube 11 into a first hole 1121 and a second hole 1122. It should be understood that the separator 112 divides the bottom end of the first receiving hole 111 into the first hole 1121 and the second hole 1122, which are not connected.

[0040] Furthermore, a second liquid inlet hole 113 is provided on the sidewall of the top end of the first receiving through hole 111 of the first cover 11, communicating with the first through hole 1121. The second liquid inlet hole 113 corresponds to the first liquid inlet hole 102. It should be understood that the laundry detergent in the laundry detergent bottle can enter the first through hole 1121 through the first liquid inlet hole 102 and the second liquid inlet hole 113, and then enter and be stored in the first receiving groove 101 through the first through hole 1121.

[0041] The liquid outlet cylinder 12 is cylindrical and is used to discharge laundry liquid, wherein a second receiving through hole 121 passes through the liquid outlet cylinder 12 .

[0043] Furthermore, a first baffle 1124 is provided on the bottom wall of the second receiving through-hole 121 to prevent the second receiving through-hole 121 from communicating with the first through-hole 1121. The first baffle 1124 is disposed on the top of the isolation plate 112. It should be understood that the provision of the first baffle 1124 ensures that the laundry liquid transferred from the first receiving groove 101 to the second through-hole 1122 is discharged directly from the second receiving through-hole 121 and does not flow into the first through-hole 1121.

[0044] In this embodiment, a downwardly inclined guide plate 1131 is provided on the inner wall of the second liquid inlet hole 113 of the first cover drum 11 , so that the laundry liquid flowing in from the second liquid inlet hole 113 is guided into the first through hole 1121 through the guide plate 1131 .

[0045] Preferably, the cross-section of first through-hole 1121 is smaller than the cross-section of second through-hole 1122. Isolation plate 112 includes a vertically disposed first partition plate 1125 and a second partition plate 1126 tilted away from second liquid inlet 113. The horizontal plane of first baffle 1124 is located at the center of guide plate 1131. It should be understood that the tilt of second partition plate 1126 away from second liquid inlet 113 is primarily intended to allow laundry liquid entering second liquid inlet 113 to flow quickly into first through-hole 1121.

[0046] The connecting structure is arranged outside the liquid outlet cylinder 12 and is used to be connected to the bottle mouth of the laundry liquid bottle.

[0047] The cover 13 is used to cover the liquid discharge cylinder 12 .

[0048] In this embodiment, the connecting structure includes a first connecting body 14 and a second connecting body 15, wherein the liquid discharge tube 12 is passed through the first connecting body 14 and the second connecting body 15, the first connecting body 14 is used to connect to the bottle mouth of the laundry detergent bottle and is arranged in the first annular ring 103 of the liquid storage 10, and the second connecting body 15 is arranged on the third annular ring 110 and is arranged outside the liquid discharge tube 12.

[0049] Preferably, the first annular ring 103 and the third annular ring 110 are formed with a first clamping groove 1011 in a circular shape.

[0050] Furthermore, the first connecting body 14 includes a second cover tube 141, a fourth annular ring 142 and a vertical clamping plate 143, wherein the second cover tube 141 is provided with a third receiving through hole 1411, and the inner wall of the third receiving through hole 1411 is provided with an internal thread for threaded connection with the external thread of the outer wall of the bottle mouth of the laundry detergent bottle, the fourth annular ring 142 is in a circular ring shape, the fourth annular ring 142 is arranged on the inner wall of the third receiving through hole 1411 of the second cover tube 141, and the fourth annular ring 142 is clamped in the first clamping groove 1011, the vertical clamping plate 143 is in a circular ring shape, and the vertical clamping plate 143 is arranged on the bottom surface of the fourth annular ring 142 along the vertical direction.

[0051] Preferably, the inner diameter of the inner hole of the vertical clamping plate 143 is equal to the outer diameter of the first annular ring 103 , so that the first annular ring 103 of the liquid storage 10 can be tightly clamped.

[0052] In this embodiment, the top wall of the inner hole of the cover 13 is provided with a protrusion 131 that is inserted into the liquid discharge cylinder 12, wherein the protrusion 131 is provided with a second receiving groove 1311. The outer wall of the cover 13 is provided with a fifth annular ring 132 that is clamped outside the second cover tube 141, and the second connector 15 is located in the third receiving through hole 1411. It should be understood that the second cover tube 141 is cylindrical, the fifth annular ring 132 is annular, and the outer diameter of the fifth annular ring 132 is larger than the outer diameter of the second cover tube 141.

[0053] Furthermore, the second connector 15 includes a sixth annular ring 151, a third cover tube 152, and a fourth cover tube 153. The sixth annular ring 151 is annular, the third cover tube 152 is annular, and the third cover tube 152 is arranged on the bottom surface of the sixth annular ring 151 and on the third annular ring 110. The fourth cover tube 153 is annular, and the fourth cover tube 153 is arranged on the top surface of the sixth annular ring 151. It should be understood that the liquid discharge cylinder 12 is inserted into the sixth annular ring 151.

[0054] Preferably, a circular extension plate 1511 is provided downwardly extending from the outer wall of the sixth annular ring 151. A second clamping groove 1512 is formed between the extension plate 1511 and the inner wall of the third receiving hole 1411 of the second cover tube 141 for retaining the side wall of the cover 13. It should be understood that the distance between the extension plate 1511 and the inner wall of the third receiving hole 1411 of the second cover tube 141 is equal to the thickness of the side wall of the cover 13.

[0055] In this embodiment, the first liquid inlet hole 102 and the second liquid inlet hole 113 have the same shape and size.

[0056] Specific working principle:

[0057] When pouring the laundry detergent, when pouring it once (the first time just after opening), the laundry detergent in the laundry detergent bottle enters the first through hole 1121 through the first liquid inlet hole 102 and the second liquid inlet hole 113, and then enters the first receiving groove 101 of the liquid storage 10 through the first through hole 1121 (in this process, the laundry detergent is not transported from the first receiving groove 101 to the second through hole 1122). At this time, the first receiving groove 101 contains a certain amount of laundry detergent (the laundry detergent entering from the first through hole 1121). When pouring it again, the laundry detergent in the first receiving groove 101 enters the liquid outlet cylinder 12 through the second through hole 1122 and is discharged from the liquid outlet cylinder 12 pours out, at this time, a fixed amount of laundry detergent is poured out, and when the bottle mouth of the laundry detergent bottle is tilted downward, laundry detergent will enter the first through hole 1121 through the first liquid inlet hole 102 and the second liquid inlet hole 113. At this time, the laundry detergent is in the first through hole 1121 and will not enter the first receiving groove 101. When the laundry detergent bottle is placed upright, the laundry detergent in the first through hole 1121 enters the first receiving groove 101, and the amount of laundry detergent that enters is fixed. Therefore, the third, fourth, and Nth pouring out will all pour out a fixed amount of laundry detergent in the first receiving groove 101, thereby realizing the quantitative output of laundry detergent.

[0058] It is worth noting that in some embodiments, the size of the liquid inlet hole is changeable to change the amount of liquid inlet into the liquid inlet hole. Specifically, the bottom surface of the first annular ring 103 is provided with a scale along the length direction of the first liquid inlet hole 102, and the top wall of the second liquid inlet hole 113 is extended with an indicator head for pointing to the scale, wherein the outer wall of the top end of the first cover tube 11 is provided with a first arc-shaped slide groove in the horizontal direction, and the inner wall of the first receiving groove 101 of the liquid storage 10 is provided with a first sliding bead (there are multiple first sliding beads) slidingly arranged in the first slide groove in the horizontal direction, so that the liquid storage 10 is slidably arranged outside the first cover tube 11 through the first sliding bead, so as to change the size of the second liquid inlet hole 113 by sliding the liquid storage 10. It should be understood that, under normal circumstances, the first liquid inlet hole 102 and the second liquid inlet hole 113 overlap, and the liquid inlet amount is mainly based on the liquid inlet amount of the first liquid inlet hole 102. When the liquid storage 10 slides relative to the first cover tube 11, the first liquid inlet hole 102 and the second liquid inlet hole 113 no longer overlap, and the side wall of the liquid storage 10 will block the second liquid inlet hole 113, thereby reducing the liquid inlet amount of the second liquid inlet hole 113. Therefore, the user can rotate the liquid storage 10 as needed to change the size of the liquid inlet amount of the second liquid inlet hole 113, which is highly flexible.

[0059] Preferably, the length of the first slide groove is smaller than the circumference of the outer wall of the top end of the first cover tube 11, so that the sliding stroke of the liquid storage 10 can be limited, and the length of the first slide groove is equal to or less than the length of the second liquid inlet hole 113 (for example, the length of the first slide groove is equal to half the length of the second liquid inlet hole 113), so that no matter how it rotates, the side wall of the liquid storage 10 will not completely block the second liquid inlet hole 113.

[0060] It should be understood that the scale provided on the bottom surface of the first annular ring 103 is used to display the amount of laundry liquid input through the liquid inlet. That is, the amount of laundry liquid that can be input through the liquid inlet can be known by which scale value the indicator head points to. Each scale value corresponds to the amount of laundry liquid input through the liquid inlet.

[0061] Further references Figure 13-18 In some embodiments, the second connector 15 is slidably disposed outside the liquid discharge cylinder 12. Specifically, a second chute 201 is horizontally disposed on the outer wall of the liquid discharge cylinder 12, and a third chute 202 is disposed on the inner wall of the second receiving through hole 121 of the liquid discharge cylinder 12 and is in the same horizontal plane as the second chute 201.

[0062] A first through-hole 2011 is defined at one end of the second chute 201, connecting one end of the second chute 201 with one end of the third chute 202. A second through-hole 2012 is defined at the other end of the second chute 201, connecting the other end of the second chute 201 with the other end of the third chute 202. The first through-hole 2011 and the second through-hole 2012 are symmetrically arranged. A plurality of second sliding beads 204 are slidably disposed within the second chute 201 on the inner wall of the inner hole of the sixth annular ring 151. A semicircular second baffle 205 is slidably disposed within the third chute 202. A first pull rope 2021 and a second pull rope 2022 are disposed within the third chute 202. It should be understood that both the first pull rope 2021 and the second pull rope 2022 are movable within the third chute 202.

[0063] Furthermore, one end of the first pull rope 2021 is connected to one end of the second baffle 205, the other end of the first pull rope 2021 passes through the first penetration hole 2011 and is connected to one side of the inner wall of the inner hole of the sixth annular ring 151, one end of the second pull rope 2022 is connected to the other end of the second baffle 205, the other end of the second pull rope 2022 passes through the second penetration hole 2012 and is connected to the other side of the inner wall of the inner hole of the sixth annular ring 151, so that when the sixth annular ring 151 is rotated in the first direction, the sixth annular ring 151 pulls the second baffle 205 to rotate in the first direction through the first pull rope 2021, so that when the sixth annular ring 151 is rotated in the second direction, the sixth annular ring 151 pulls the second baffle 205 to rotate in the second direction through the second pull rope 2022, and the first direction is opposite to the second direction.

[0064] It should be understood that the first baffle 1124 and the second baffle 205 have the same shape and size, and the length of the third slide groove 202 is greater than half the circumference of the second receiving through hole 121, so that the second baffle 205 can rotate to both ends of the first baffle 1124. Under normal circumstances, the second baffle 205 is above the first baffle 1124 ( Figure 15 In one way, the optimal way, the distance between the second baffle 205 and the first baffle 1124 is 0-5 mm), so that the laundry liquid flowing from the second through hole 1122 to the liquid outlet cylinder 12 is determined by the area of ​​the second through hole 1122. When the second connector 15 is rotated to drive the sixth annular ring 151 to slide, the sixth annular ring 151 drives the second baffle 205 to slide in the third chute 202 through the pull rope, so that the second baffle 205 partially blocks the liquid outlet of the second through hole 1122 to change the size of the liquid outlet, thereby achieving a change in the liquid outlet volume. In this way, the amount of laundry liquid output can be adjusted as needed, which is more flexible.
