[0008] In one specific implementation, the card block includes an arc plate with its inner arc surface facing the housing. One end of the arc plate is provided with a connecting plate, and the end of the connecting plate opposite to the arc plate is provided with a folding plate. The connecting plate is provided with a first inclined guide surface that matches the connecting groove and a second inclined guide surface that matches the male connector.

[0009] In one specific implementation, the connector body is provided with a plurality of limiting blocks, and the elastic element is located between the plurality of limiting blocks and the shell.

[0010] In one specific implementation scheme, the end of the connector body facing away from the connecting pipe is provided with a retaining ring, and the inner edge of the shell is provided with a plurality of retaining blocks, the ends of the plurality of retaining blocks facing the retaining ring respectively contacting the retaining ring.

[0011] In one specific implementation scheme, the connector body is provided with a connecting sleeve, and the inner edge of the connecting sleeve is provided with a plurality of threaded blocks for threaded connection with the threaded part of the bottle mouth.

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses a quick-connector.

[0024] Reference Figure 1 and Figure 2 The quick-connector includes a female connector and a male connector mounted on the cleaning machine. The female connector includes a connector body 1 with a flow hole 2 at its center. A connecting pipe 3 communicating with the flow hole 2 is provided on the connector body 1. In this embodiment, the connecting pipe 3 is a flexible hose. The connector body 1 is connected to the threaded portion of the bottle neck, and the end of the connecting pipe 3 facing away from the cleaning machine is inserted into the beverage bottle. The end of the connector body 1 facing away from the connecting pipe 3 is connected to the male connector of the cleaning machine via a quick-connect device. Therefore, when water needs to be drawn from the beverage bottle to the cleaning machine, one end of the connector body 1 is connected to the threaded portion of the beverage bottle neck, and the connecting pipe 3 is inserted into the beverage bottle. The other end of the connector body 1 connects the female connector to the male connector of the cleaning machine via a quick-connect device. When the cleaning machine is started, the liquid in the beverage bottle flows into the cleaning machine through the connecting pipe 3 and the flow hole 2, supplying water to the cleaning machine. The position of the connecting pipe 3 is fixed by the connector body 1, preventing displacement and shaking, thus ensuring stable water supply and improving water supply efficiency.

[0025] In traditional methods, the water pipe is directly inserted into the bottle opening. This can easily cause the pipe to slip out of the bottle opening or fall to the bottom due to negative pressure during water pumping, user movement, or tilting, resulting in insufficient water intake or even air being drawn in. In this embodiment, the female connector is directly connected to the threaded portion of the bottle opening via the connector body 1, providing a more secure connection. The connecting pipe 3 is fixed in place inside the bottle, preventing it from easily falling off or shifting, thus avoiding accidental flow interruption or dry running, and improving the safety and reliability of the usage process.

[0026] Users simply need to screw the female connector body 1 onto the threaded part of the beverage bottle's neck, and then connect the female connector to the male connector of the cleaning machine via a quick-connect device to complete the water supply connection. No complicated operations or additional tools are required. In this solution, the male connector can be designed to directly connect to the existing water suction end of the cleaning machine, while the female connector connects to the beverage bottle via a standard or common bottle neck thread. This eliminates the need for significant modifications to the overall structure of the cleaning machine or custom-made beverage bottles, making it compatible with common beverage bottles and cleaning machine equipment. It has excellent adaptability and promotional value. This embodiment uses the common cola bottle's neck thread as an example for illustration.

[0027] Reference Figure 2 , Figure 3 and Figure 4 The quick-connect device includes a connecting ring 4 fixedly connected to the connector body 1. A housing 5 is fitted around the outer edge of the connecting ring 4. A slider 6 is fixedly connected to the surface of the connector body 1 facing the housing 5. A groove 7 matching the size of the slider 6 is opened on the inner edge of the housing 5. The slider 6 is slidably connected in the groove 7. The groove 7 limits the movement direction of the slider 6, so that the housing 5 can only move along the slider 6 when it moves along the connector body 1, thereby improving the stability of the housing 5 when it moves along the connector body 1.

[0028] Reference Figure 2 , Figure 3 and Figure 4 The connector body 1 is provided with several quick-release components connected to the male connector. In this embodiment, three quick-release components are used as an example. The three quick-release components are evenly distributed along the outer periphery of the connector body 1. Each of the three quick-release components includes two baffles 8 provided on the connector body 1. A connecting groove 9 is provided on the connector body 1 between the two baffles 8. A locking block 10 is slidably connected in the connecting groove 9. The male connector is provided with a locking groove that matches the size of the locking block 10. An elastic element 11 is provided between the baffles 8 and the connecting ring 4. A stop block 12 is fixedly connected to the inner edge of the shell 5. The stop block 12 is located between the two baffles 8 and the end of the stop block 12 facing the connecting ring 4 contacts the elastic element 11. In this embodiment, the elastic element 11 is a compression spring as an example.

[0029] Reference Figure 2 , Figure 3 and Figure 4The locking block 10 includes an arc plate 25. A protrusion 26 is fixedly connected to the outer edge of the connector body 1. The outer arc surface of the arc plate 25 is mounted on the protrusion 26. The inner arc surface of the arc plate 25 faces the housing 5. A connecting plate 13 is fixedly connected to one end of the arc plate 25. A folding plate 14 is fixedly connected to the end of the connecting plate 13 away from the arc plate 25. The connecting plate 13 is provided with a first inclined guide surface 15 that matches the connecting groove 9 and a second inclined guide surface 16 that matches the male connector. The first inclined guide surface 15 guides the locking block 10 along the moving direction of the connecting groove 9, improving the stability of the locking block 10 during movement. The second inclined guide surface 16 guides the male connector end to be inserted into the connector body 1, making it easier for the locking block 10 to be smoothly inserted into the male connector's slot.

[0030] Therefore, when water needs to be drawn from a beverage bottle to the washing machine, one end of the connector body 1 is connected to the threaded part of the bottle neck, and the connecting pipe 3 is inserted into the beverage bottle. The male connector is set on the water inlet end of the washing machine. The operator inserts the male connector into the inner edge of the connector body 1. During the insertion process, the male connector pushes the locking block 10, causing the locking block 10 to displace and retract. The arc plate 25 contacts the elastic element 11 at the end facing the connecting pipe 3. When the locking block 10 of the female connector is inserted into the locking groove of the male connector, the compression spring presses against the locking element. Block 10 applies force to engage with the slot, enabling quick connection between the female head and the male head on the cleaning machine. When the female head needs to be removed from the male head, the operator pulls the housing 5 towards the connecting pipe 3. During the movement, the abutment block 12 on the inner edge of the housing 5 applies force to the elastic element 11, compressing the elastic element 11 and separating it from the block 10. As the operator pulls the male head out of the connector body 1, the block 10 retracts and disengages from the slot, thus disassembling the female head from the male head.

[0031] Reference Figure 2 , Figure 3 and Figure 4 Six limiting blocks 17 are fixedly connected to the connector body 1. The six limiting blocks 17 are evenly distributed along the outer circumference of the connector body 1. The elastic element 11 is located between the six limiting blocks 17 and the housing 5. The limiting blocks 17 limit the position of the compression spring, reduce the possibility of radial movement of the compression spring, and improve the stability of the compression spring position. A retaining ring 18 is fixedly connected to the end of the connector body 1 away from the connecting pipe 3. Several stop blocks 19 are fixedly connected to the inner edge of the housing 5. The ends of the several stop blocks 19 facing the retaining ring 18 respectively contact the retaining ring 18. The retaining ring 18 limits the position of the stop blocks 19, reducing the possibility of the housing 5 detaching from the connector body 1.

[0032] Reference Figure 2 , Figure 3 and Figure 5A connecting sleeve 20 is fixedly connected to the connector body 1. The inner edge of the connecting sleeve 20 is provided with several threaded blocks 21 for threaded connection with the bottle neck threaded portion. The operator can connect the connecting sleeve 20 to the bottle neck threaded portion via threaded connection, enabling a detachable connection between the quick-connect fitting and the beverage bottle. Two contact blocks 22 are fixedly connected to the connecting sleeve 20. These two contact blocks 22 insert into the bottle neck threaded portion and contact the inner wall of the bottle neck threaded portion. In this embodiment, the two contact blocks 22 are set in an arc shape according to the shape of the beverage neck, and the two arc-shaped contact blocks 22 are arranged opposite to each other. Therefore, when the connecting sleeve 20 is threadedly connected to the bottle neck threaded portion, the two contact blocks 22 insert into the bottle neck threaded portion and contact the inner wall of the bottle neck threaded portion. Through the physical contact between the contact blocks 22 and the inner wall of the bottle neck, additional radial support and frictional resistance are formed, effectively reducing loosening or shaking between the connecting sleeve 20 and the bottle neck due to vibration generated during the operation of the washing machine, thus improving the overall reliability of the connection.

[0033] Reference Figure 2 , Figure 3 and Figure 5 The connecting sleeve 20 has a groove 23 that matches the size of the connecting pipe 3. The connecting pipe 3 is partially inserted into the groove 23, which limits the position of the connecting pipe 3 and improves the stability and firmness of the connection between the connecting pipe 3 and the connector body 1. The connecting sleeve 20 has a vent hole 24, which balances the air pressure inside the beverage bottle, making it less likely for the washing machine to suck up the bottle body when drawing water from it. The outer peripheral wall of the shell 5 has several annular grooves 27, and the outer peripheral wall of the connecting sleeve 20 has several anti-slip grooves 287. The annular grooves 27 and the anti-slip grooves 287 increase the friction, making it less likely for the operator to slip out of their hand.

[0034] It should be noted that the connector body 1 of the quick connector in this application embodiment can be replaced with various forms according to actual needs to meet special interface requirements. The connector body 1 can also be fitted onto a faucet for use. When used in places with insufficient space, such as a washbasin, it can also fill beverage bottles or other water storage devices that are inconvenient to fill with water, making it more convenient.

[0035] The implementation principle of this application embodiment is as follows: When water needs to be drawn from a beverage bottle to the cleaning machine, one end of the connector body 1 is connected to the threaded part of the bottle mouth of the beverage bottle and the connecting pipe 3 is inserted into the beverage bottle. The male end is set on the water inlet end of the cleaning machine. The operator inserts the male end into the inner edge of the connector body 1. During the initial insertion process, the male end pushes the locking block 10 to cause the locking block 10 to move and retract. The end of the arc plate 25 facing the connecting pipe 3 contacts the elastic element 11. When the locking block 10 of the female end is inserted into the locking groove of the male end, the compression spring applies a force to the locking block 10 to push the locking block 10 to engage with the locking groove, realizing the quick connection between the female end and the male end on the cleaning machine. The cleaning machine is started, and the liquid in the beverage bottle flows into the cleaning machine through the connecting pipe 3 and the flow hole 2 to supply water to the cleaning machine. The position of the connecting pipe 3 is fixed by the connector body 1 and is not easy to shift or shake. The water supply is stable and the water supply efficiency is improved. When it is necessary to detach the female head from the male head, the operator pulls the housing 5 towards the connecting pipe 3. During the movement of the housing 5, the abutment block 12 on the inner edge of the housing 5 applies force to the elastic element 11, causing the elastic element 11 to compress and separate from the locking block 10. During the process of the operator pulling the male head out of the connector body 1, the locking block 10 retracts and disengages from the slot, thus realizing the detachment of the female head from the male head.
