Description

Technical Field

[0001] This invention belongs to the technical field of laundry detergent bottle bodies, and particularly relates to a bottle body for packaging laundry detergent. Background Technology

[0002] Laundry powder has always been the dominant product for washing clothes. However, it cannot completely dissolve during use, and the residue can easily damage clothes. Laundry liquid, on the other hand, mainly consists of nonionic surfactants that can penetrate deep into the fabric fibers to clean more thoroughly. It dissolves completely and quickly, and is easy to rinse.

[0003] Chinese invention patent CN217457052U discloses a portable laundry detergent bottle, comprising a bottle body and a cap. A connecting box is fixedly connected to the upper surface of the cap. A locking mechanism is provided inside the connecting box. The locking mechanism consists of a bidirectional screw, two connecting blocks, and two locking plates. The two ends of the bidirectional screw are rotatably connected to the two transverse sides inside the connecting box. The two connecting blocks are symmetrically rotated and sleeved on the two transverse ends of the bidirectional screw. Connecting grooves are symmetrically opened on the transverse sides of the upper surface of the connecting box. Connecting rods are fixedly connected to the upper surfaces of the two connecting blocks. The upper ends of the connecting rods extend to the upper surface of the connecting box through the connecting grooves. The two locking plates are respectively fixedly connected to the upper ends of the two connecting rods. A pump tube is fixedly connected to the center of the upper surface of the connecting box.

[0004] However, the above-mentioned patents have the following shortcomings:

[0005] 1. The above-mentioned patent can change the volume of the device, so that users can change the size of the device according to their needs, making the device easy to carry. However, the above-mentioned patent requires users to actively adjust the volume of the device, and cannot automatically adjust the volume of the device according to the content of laundry detergent in the device, thus making the use of the device not smart and convenient enough.

[0006] 2. The above-mentioned patent requires the laundry detergent to be extracted by squeezing the bottle or by the weight of the detergent itself. This method cannot extract the detergent in a precise quantity, which may result in too much detergent being extracted at once, thus causing waste. Summary of the Invention

[0007] This invention provides a bottle for packaging laundry detergent, aiming to solve the problems mentioned in the background art. The aforementioned patents require users to actively adjust the volume of the device, rather than automatically adjusting the volume according to the content of laundry detergent inside, thus making the device less intelligent and convenient to use. Furthermore, the aforementioned patents require squeezing the bottle or using the weight of the laundry detergent itself to remove the detergent, which cannot measure the amount of detergent removed at one time, potentially leading to excessive amounts of detergent being removed and wasting the detergent.

[0008] The present invention is implemented as follows: a bottle for packaging laundry detergent includes a base, a bottle body fixedly connected to the top of the base, the bottle body being configured as a foldable corrugated shape, a mounting shell fixedly connected to the top of the bottle body, a connecting chamber threadedly connected to the middle of the mounting shell, a liquid outlet chamber connected to the side wall of the connecting chamber, a liquid inlet pipe connected to the bottom of the connecting chamber, the liquid inlet pipe being configured as a foldable corrugated shape, a fixing shell fixedly connected to the inner bottom wall of the bottle body, a plurality of through holes opened on the outer periphery of the fixing shell, and the top of the fixing shell communicating with the liquid inlet pipe;

[0009] A compression mechanism for compressing the bottle is provided between the base and the mounting shell.

[0010] The connecting chamber is equipped with a liquid dispensing mechanism for controlling the liquid dispensing volume of the liquid dispensing chamber.

[0011] Preferably, the compression mechanism includes a through groove and a fixed shaft, the through groove being disposed through the bottom of the mounting housing, and the number of through grooves being multiple;

[0012] The number of fixed shafts is the same as the number of through slots. The fixed shafts are located inside the mounting housing. The ends of the fixed shafts are fixedly connected to the inner wall of the mounting housing. A winding drum is rotatably connected to the outer circumference of the fixed shafts. A spring is provided between the winding drum and the fixed shafts. One end of the spring is fixedly connected to the fixed shafts, and the other end of the spring is fixedly connected to the inner wall of the winding drums.

[0013] A tensioning rope is wound around the outer periphery of the take-up drum. One end of the tensioning rope is fixedly connected to the outer periphery of the take-up drum, and the other end of the tensioning rope is fixedly connected to the base. The tensioning rope passes through an adjacent through slot.

[0014] When the base is furthest from the mounting shell, the bottle between the base and the mounting shell is in an unfolded state, and its internal volume is at its maximum. At this time, the spring between the winding drum and the fixed shaft is in a taut state. When the taut spring springs back, the winding drum will wind up the outer tension rope, thereby pulling the base and the mounting shell closer together through multiple tension ropes, thus compressing the bottle between the base and the mounting shell, thereby reducing the volume of the bottle.

[0015] Preferably, the liquid dispensing mechanism includes a sealing structure for sealing the connecting chamber and a reset structure for controlling the reset of the sealing structure.

[0016] Preferably, the sealing structure includes a sealing ring and an mounting cylinder. The sealing ring is disposed inside the communicating chamber, and the outer periphery of the sealing ring is fixedly connected to the inner wall of the communicating chamber. The mounting cylinder is disposed through the top of the communicating chamber, and a push rod is disposed through the middle of the mounting cylinder. The push rod is slidably connected to the mounting cylinder, and a sealing plate is fixedly connected to the bottom of the push rod. The sealing plate corresponds to the bottom of the sealing ring.

[0017] When the push rod moves the sealing plate against the sealing ring, the connecting chamber is sealed. At this time, the bottle cannot be compressed due to air pressure. When the push rod moves the sealing plate and sealing ring to a misalignment, the connecting chamber is in a connected state. When the bottle is compressed and its volume decreases, the laundry detergent in the bottle will enter the fixed shell through the through hole and enter the connecting chamber through the liquid inlet pipe. Finally, the laundry detergent will be discharged through the sealing ring and the liquid outlet chamber.

[0018] Preferably, the reset structure includes a piston plate with a through mounting hole in the middle. A connector is fixedly connected to the bottom of the piston plate, and the bottom of the connector is fixedly connected to a push rod. A reset spring is provided at the bottom of the connector, and the reset spring is sleeved on the outer periphery of the push rod. One end of the reset spring abuts against the inner wall of the mounting cylinder, and the other end of the reset spring abuts against the connector. An adjustment component for adjusting the reset speed of the sealing plate is provided in the middle of the piston plate.

[0019] The piston plate has multiple fixing holes on its surface, and the multiple fixing holes are distributed around the center of the piston plate.

[0020] A connecting cylinder is fixedly connected to the middle of the fixing hole. A connecting groove is provided on the outer periphery of the connecting cylinder. A sealing groove is provided on the bottom of the connecting cylinder. A sealing plug is slidably disposed inside the connecting cylinder. A compression spring is provided on the top of the sealing plug. The top of the compression spring abuts against the inner wall of the connecting cylinder, and the bottom of the compression spring abuts against the sealing plug.

[0021] By pressing the connector with a return spring, the connector will drive the push rod and the sealing plate to move upward, so that the sealing plate abuts against the sealing ring, thereby sealing the connecting chamber.

[0022] Preferably, the adjusting component includes an adjusting cylinder with a through mounting hole at the bottom. The bottom of the adjusting cylinder is fixedly connected to the mounting hole. Adjusting grooves are provided on both sides of the adjusting cylinder, and a sliding groove is provided on the inner wall of the adjusting cylinder. An adjusting block is slidably arranged inside the adjusting cylinder. A threaded rod is threadedly connected to the middle of the adjusting block. The middle of the threaded rod is rotatably connected to the end of the adjusting cylinder, and a knob is fixedly connected to the end of the threaded rod.

[0023] By pressing the knob, the piston plate can be moved downward in the connecting cylinder by adjusting the cylinder. At this time, the piston plate will cause the sealing plate to separate from the sealing ring through the connecting piece and the push rod, so that the connecting chamber is in a connected state. During this process, part of the gas at the bottom of the piston plate will be discharged through the adjusting groove on the outer periphery of the adjusting cylinder, and part of the gas will be discharged through the connecting groove on the outer periphery of the connecting cylinder due to the air pressure.

[0024] When the knob is no longer pressed, the return spring will cause the piston plate to slide upward in the connecting cylinder. Therefore, the bottom of the piston plate is in a negative pressure state. At this time, the outside air enters the connecting cylinder through the adjustment groove on the outer circumference of the adjustment cylinder at a certain flow rate, which causes the sealing plate to rise slowly until the sealing plate abuts against the sealing ring, thereby sealing the connecting chamber.

[0025] During the process of the sealing plate and sealing ring being unsealed and then resealed, the shrinkage of the bottle will cause the laundry detergent in the bottle to be discharged into the dispensing chamber in a measured amount. As the laundry detergent is discharged from the bottle, the volume of the bottle can be reduced, thereby reducing the overall volume of the device. As a result, the device gradually becomes smaller during use, making it easier to carry.

[0026] Furthermore, by rotating the knob, the position of the adjusting block inside the adjusting cylinder can be adjusted via the threaded rod, thereby adjusting the air inlet and outlet area of ​​the adjusting groove, thus regulating the flow rate of outside air into the adjusting cylinder, which in turn adjusts the reset time of the sealing plate and sealing ring, and consequently adjusts the amount of laundry detergent dispensed by the device, thereby improving the applicability of the device.

[0027] Preferably, a limiting block is fixedly connected to the bottom wall inside the connecting compartment, and the number of the limiting blocks is set to multiple, with the multiple limiting blocks distributed around the center of the connecting compartment;

[0028] By setting a limit block, the sealing plate can be prevented from moving to the bottom of the connecting chamber, thus preventing the top of the inlet pipe from being sealed by the sealing plate after the knob is pressed.

[0029] Compared with the prior art, the beneficial effects of the present invention are: a bottle for packaging laundry detergent according to the present invention:

[0030] 1. By setting up a compression mechanism, the corrugated bottle can be compressed by external pressure. During this process, the laundry detergent inside the bottle can be squeezed out of the device. As the laundry detergent is used, the size of the device can be reduced, making it convenient to carry.

[0031] 2. By setting up a dispensing mechanism, the laundry detergent in the bottle can be dispensed in a measured amount by pressing the knob, thus avoiding the waste of a large amount of laundry detergent being squeezed out at once. Furthermore, the dispensing volume of the device can be adjusted by rotating the knob, thereby improving the applicability of the device. Attached Figure Description

[0066] Working principle and usage process of this invention:

[0067] When the distance between the base 1 and the mounting shell 12 is the farthest, the bottle 11 located between the base 1 and the mounting shell 12 is in the unfolded state. At this time, the volume of the bottle 11 is the largest. At this time, the spring 24 between the winding drum 23 and the fixed shaft 22 is in a taut state. When the taut spring 24 rebounds, the winding drum 23 will wind up the tightening rope 25 on its outer periphery. Thus, the base 1 and the mounting shell 12 are pulled closer through multiple tightening ropes 25, thereby compressing the bottle 11 located between the base 1 and the mounting shell 12, thereby reducing the volume of the bottle 11.

[0068] At this time, by pressing the knob 3256, the piston plate 321 can be driven to slide downward in the mounting cylinder 312 through the adjusting cylinder 3251. At this time, the piston plate 321 will drive the sealing plate 314 to separate from the sealing ring 311 through the connecting piece 323 and the push rod 313, thereby making the connecting chamber 13 in a connected state. This allows the laundry detergent in the bottle 11 to enter the fixed shell 16 through the through hole 17 and enter the connecting chamber 13 through the liquid inlet pipe 15. Finally, the laundry detergent is discharged through the sealing ring 311 and the liquid outlet chamber 14.

[0069] During the above process, part of the gas at the bottom of the piston plate 321 will be discharged through the adjustment groove 3252 on the outer periphery of the adjustment cylinder 3251, and part of the gas will be discharged through the connecting groove 328 on the outer periphery of the connecting cylinder 327 due to the air pressure pushing open the sealing plug 3210.

[0070] When the knob 3256 is no longer pressed, the return spring 324 will cause the piston plate 321 to slide upward in the mounting cylinder 312. Therefore, the bottom of the piston plate 321 is in a negative pressure state. At this time, the outside air enters the regulating cylinder 3251 through the regulating groove 3252 on the outer periphery of the regulating cylinder 3251 at a certain flow rate, so that the sealing plate 314 slowly rises until the sealing plate 314 abuts against the sealing ring 311, thereby sealing the connecting chamber 13.

[0071] During the process of sealing the sealing plate 314 and sealing the sealing ring 311 from unsealing to resealing, the shrinkage of the bottle body 11 will cause the laundry detergent in the bottle body 11 to be discharged in a measured amount into the liquid outlet 14. As the laundry detergent in the bottle body 11 is discharged, the volume of the bottle body 11 can be reduced, thereby reducing the overall volume of the device. As a result, the device gradually becomes smaller during use, making it easier to carry.

[0072] Furthermore, by rotating the knob 3256, the position of the adjusting block 3254 within the adjusting cylinder 3251 can be adjusted via the threaded rod 3255, thereby adjusting the air inlet and outlet area of ​​the adjusting groove 3252. This, in turn, regulates the flow rate of outside air into the adjusting cylinder 3251, which in turn regulates the reset time of the sealing plate 314 and the sealing ring 311, ultimately adjusting the amount of laundry detergent dispensed by the device. This improves the applicability of the device.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
