Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and more specifically, to an anti-overflow extraction device. Background Technology

[0002] With the fast pace of modern family life and rising demands for quality, family-sized and large-package products have gained a significant place in the consumer market due to their affordability and convenience. Especially at family gatherings and festive celebrations, large-bottle beverages such as milk and juice have become indispensable choices. These large bottles not only meet the drinking needs of family members and guests but are also widely popular due to their affordable prices and convenient storage. However, in actual use, the problem of pouring large bottles has become increasingly apparent, particularly when frequently serving multiple guests. This not only makes the process inconvenient but also poses a risk of spillage, affecting the cleanliness and atmosphere of the gathering.

[0003] To address these issues, home beverage dispensers have emerged on the market. These devices use a push-button switch to control the pump's activation and deactivation, allowing liquid to be drawn from large bottles and poured into disposable cups. This design significantly improves ease of use and accuracy, effectively reducing liquid splashing and making family gatherings more organized and tidy.

[0004] However, while these extraction devices significantly improve the user experience, some liquid remains in the outlet tube after the user finishes using the device and turns off the pump by pressing the switch. This residual liquid, deprived of pump pressure, slowly flows out under its own weight, eventually dripping onto tabletops or other surfaces, causing unnecessary dirt. This not only affects environmental cleanliness but may also negatively impact the user experience. Utility Model Content

[0005] In order to overcome the problem that after the pump body is turned off in the existing extraction device, some liquid will remain in the outlet pipe. After the residual liquid loses the pressure support generated by the pump body, it will slowly flow out along the outlet under its own gravity and eventually drip onto the table or other placement surface, causing unnecessary dirt. This utility model provides an anti-overflow extraction device.

[0006] The technical solution of this utility model is as follows:

[0007] An overflow prevention extraction device, comprising:

[0008] The main housing contains a control module and a control switch, which are electrically connected. The main housing is also connected to a liquid outlet pipe, and an adjustable valve is provided at the liquid outlet of the liquid outlet pipe.

[0009] The pump is electrically connected to the control module and is also connected to the liquid outlet pipe.

[0010] When the control switch is in the ON state, the control module controls the extraction pump to rotate around the first direction and extract liquid to the liquid outlet pipe, and the valve opens towards the liquid outlet.

[0011] The control switch changes from the on state to the off state. The control module controls the extraction pump to rotate one revolution around the second direction and then stop. The first direction and the second direction are opposite directions. The valve opens towards the extraction pump and then closes.

[0012] According to the above-described scheme of this utility model, the valve includes at least three valves, and there is a slit between adjacent valves that can be automatically opened under pressure.

[0013] According to the above-described scheme of this utility model, the main housing includes an upper housing and a lower housing, the upper housing and the lower housing are detachably connected, and the upper housing and the lower housing together form a sealed chamber, and the control module is placed in the sealed chamber.

[0014] According to the above-described scheme of this utility model, the top surface of the upper shell is recessed downward to form a placement groove, which is used to install the liquid outlet pipe.

[0015] According to the above-described solution of this utility model, the lower housing is provided with a connecting pipe, the upper end of the connecting pipe extends upward into the placement slot, the liquid outlet pipe is connected and sealed to the upper end of the connecting pipe, and the lower end of the liquid outlet pipe extends downward to form a mounting part, the mounting part is provided with several teeth for fitting a suction tube.

Terms such as "upper," "lower," "left," "right," "front," "rear," and "bottom" indicate orientations or positions based on the orientations or positions shown in the accompanying drawings, and are only for ease of description and should not be construed as limiting the present technical solution.

[0032] It's worth noting that household beverage dispensers have appeared on the market. These devices use a push-button switch to control the pump's start and stop, allowing liquid to be drawn from large bottles and poured into disposable cups. This design significantly improves ease of use and accuracy, effectively reducing liquid splashing and making family gatherings cleaner and more organized.

[0033] However, while these extraction devices significantly improve the user experience, some liquid remains in the outlet tube after the user finishes using the device and turns off the pump by pressing the switch. This residual liquid, deprived of pump pressure, slowly flows out under its own weight, eventually dripping onto tabletops or other surfaces, causing unnecessary dirt. This not only affects environmental cleanliness but may also negatively impact the user experience.

[0034] like Figures 1-6 As shown, this embodiment provides an anti-overflow extraction device. After the control switch 12 is closed, the control module 11 controls the extraction pump 40 to rotate around the second direction. The extraction pump 40 reverses and drives the liquid in the outlet pipe 20 to flow back. During the liquid flow back, the valve 21 also opens in the flow back direction to ensure pressure balance in the direction of the extraction pump 40. After the extraction pump 40 stops working, the valve 21 closes to prevent the residual liquid in the outlet pipe 20 from overflowing, thus playing an anti-overflow role.

[0035] Specifically, the overflow prevention and extraction device includes a main housing 10 and an extraction pump 40. The main housing 10 is equipped with a control module 11 and a control switch 12, which are electrically connected. The main housing 10 is also connected to an outlet pipe 20, and an adjustable valve 21 is provided at the outlet of the outlet pipe 20. The extraction pump 40 is electrically connected to the control module 11 and is also connected to the outlet pipe 20.

[0036] When the user turns the control switch 12 to the ON position, the control module 11 receives the signal and controls the extraction pump 40 to rotate in the first direction and extract liquid to the outlet pipe 20. At the same time, the valve 21 opens towards the outlet, allowing the liquid to flow out smoothly.

[0037] When the user needs to stop the extraction process, they simply switch the control switch 12 from the on state to the off state. Upon receiving the signal, the control module 11 controls the extraction pump 40 to rotate one revolution in the second direction and then stop. The extraction pump 40 generates a reverse force, pushing the liquid in the outlet pipe 20 back into the storage container. Simultaneously, the valve 21 opens towards the extraction pump 40 to balance the pressure during the backflow process. After the extraction pump 40 stops working, the valve 21 automatically closes, further preventing residual liquid in the outlet pipe 20 from overflowing. Through the reverse rotation of the extraction pump 40 and the automatic adjustment of the valve 21, liquid overflow during the extraction process can be effectively prevented. The first and second directions are opposite directions.

[0038] In one embodiment, valve 21 includes at least three valves 211, with slits between adjacent valves 211 that open automatically under pressure. These slits open and close automatically under the action of the extraction pump 40, making the automatic opening and closing of the slits more flexible and controllable. Specifically, the suction or thrust of the extraction pump 40 during operation can precisely control and influence the opening and closing state of these slits, allowing the user to quickly adjust the opening degree of valve 21 according to actual needs.

[0039] In one embodiment, the main housing 10 includes an upper housing 13 and a lower housing 14, which are detachably connected and together form a sealed chamber, in which the control module 11 is placed.

[0040] The top surface of the upper housing 13 is recessed downward to form a placement groove 131. The placement groove 131 is used to install the liquid outlet pipe 20, ensuring that the liquid outlet pipe 20 can be stably installed on the upper housing 13, which facilitates subsequent connection and operation.

[0041] The lower housing 14 is provided with a connecting pipe 141. The upper end of the connecting pipe 141 extends upward into the placement slot 131. The liquid outlet pipe 20 is connected to the upper end of the connecting pipe 141 and is sealed. The lower end of the liquid outlet pipe 20 extends downward to form a mounting part 142. The mounting part 142 is provided with a plurality of teeth 1421 for fitting the straw 30. The teeth 1421 provide a reliable fitting point so that the straw 30 can be firmly fitted onto the liquid outlet pipe 20 and is not easy to fall off.

[0042] The other end of the suction pipe 30 is connected to the extraction pump 40. The extraction pump 40 serves as the power source for the entire system, drawing liquid from the storage container through the suction pipe 30 and delivering it to the outlet along the outlet pipe 20. This design not only ensures smooth fluid flow but also significantly improves the overall system's operating efficiency and stability.

[0043] In one embodiment, the device further includes a mounting cap 50 with threads on its inner surface. The threads of the mounting cap 50 engage with the threads on the storage container, allowing the entire anti-overflow extraction device to be securely installed on the storage container. The mounting cap 50 is fitted onto the mounting portion 142, and an abutment block 1422 extends outward from the mounting portion 142. The mounting cap 50 is positioned above the abutment block 1422, which prevents the mounting cap 50 from detaching from the mounting block, ensuring the stability and safety of the device during use.

[0044] The control switch 12 is located on the side of the main housing 10 near the outlet pipe 20. The control switch 12 has a spring 121, allowing the user to control its opening and closing with a simple pressing action. A pressing arm 15 is located outside the main housing 10. One end of the pressing arm 15 is hinged to the main housing 10, while the other end is suspended. A pressing block 151 is located on the pressing arm 15, used to press the spring 121 of the control switch 12 to control its opening and closing. The user can easily press the spring 121 of the control switch 12 using the pressing block 151 on the pressing arm 15.

[0045] The main housing 10 has a soft rubber sleeve 16 at the corresponding position of the control switch 12. The soft rubber sleeve 16 surrounds the groove of the main housing 10 where the spring piece 121 is located. The soft rubber sleeve 16 provides a relatively sealed cavity for the control switch 12, effectively protecting the control switch 12 from damage even if the device is splashed or leaked during use. Furthermore, the soft rubber sleeve 16 does not affect the opening and closing of the control switch 12, ensuring the normal use of the extraction device.

[0046] It also includes a power module 17, which is located inside the main housing 10 and is electrically connected to the control module 11. The power module 17 ensures that the device can operate continuously and stably, providing users with a more convenient and efficient experience.

[0047] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.

[0048] The present utility model patent has been described above with reference to the accompanying drawings.
