Description

Technical Field

[0001] The present invention relates to the technical field of daily necessities, in particular to a liquid metering device. Background Art

[0002] Small, bottled drinking water and beverages are widely used in homes, offices, and outdoors. Traditional drinking methods often rely on pouring, pressing a valve, or using a separate manual dispenser. While simple, these systems present numerous inconveniences and potential safety hazards.

[0003] Existing common drinking water holders typically dispense liquid via gravity, lacking effective volume control. This makes it difficult to control the flow of liquid during pouring, which can easily cause splashing or excessive outflow. Furthermore, most holders lack effective sealing and opening / closing mechanisms, making the bottle opening susceptible to contamination after use, posing a hygiene risk.

[0004] To improve liquid delivery efficiency, some drinking water devices use knob-type valves or rubber sealing plugs to control liquid release. However, these structures are not only cumbersome to operate, but their sealing effectiveness is also limited by manual operation precision, making them prone to leakage after prolonged use. Furthermore, bottle replacement typically requires tightening the screw or inserting and removing the sealing ring, a complex process that is particularly inconvenient with large bottles or insufficient hand strength, affecting the user experience.

[0005] In response to the demand for dispensing small bottled liquids, the market still lacks a drinking water dispensing bracket that combines efficient quick connection, intelligent opening and closing, adjustable flow and self-sealing capabilities.

[0006] Therefore, there is an urgent need for a small drinking water dispensing bracket with a compact structure, easy operation, strong controllability and self-opening and closing functions to meet the actual needs of convenient and safe drinking water in modern life. Summary of the Invention

[0007] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0008] To this end, the technical solution adopted by the present invention is as follows: a liquid metering device, comprising: a bracket, a control valve group, a quick-connect sleeve and a check valve head, wherein a joint seat and a ball tube seat are fixedly mounted on the surface of the bracket, and a liquid outlet pipe is movably sleeved on the surface of the ball tube seat, the control valve group is fixed to the surface of the bracket, and its upper and lower ends are respectively connected to the bottom end of the joint seat and the top surface of the ball tube seat, and the quick-connect sleeve is fixed to the top end of the joint seat; The control valve group includes: a valve seat, a turntable and a plurality of valve discs, the turntable is rotatably sleeved on the inner side of the valve seat, and a turn ear is fixedly connected to the surface of the turntable, a sealing strip is fixedly installed on the inner side of the turntable, and the plurality of valve discs are distributed in a circumferential direction, and the top surfaces thereof are in sliding contact with the bottom surface of the sealing strip, the opposing surfaces of the turntable and the valve seat are respectively provided with a linear slide groove and an inclined slide groove, and the upper and lower surfaces of the valve disc are respectively provided with a sliding protrusion and a sliding pin, which are respectively slidably sleeved on the inner sides of the linear slide groove and the inclined slide groove; The quick-connect assembly comprises: a fixed sleeve seat, a locking sleeve and a plurality of locking beads, wherein the locking sleeve is slidably sleeved on the outer side of the fixed sleeve seat, and the locking beads are movably mounted on the surface of the fixed sleeve seat, and the outer periphery of the locking beads is in sliding contact with the inner side of the locking sleeve; The stop valve head includes a joint pipe and a valve core body rotatably installed on the inner side of the joint pipe. The outer periphery of the joint pipe is adapted to the inner side of the fixed sleeve, and the surface of the valve core body is provided with a magnetic ball and a valve ring. A permanent magnet is fixedly installed on the inner side of the fixed sleeve to attract the magnetic ball to move obliquely.

[0009] Specifically, the systematic combination of the bracket, control valve assembly, quick-connect assembly, and check valve head achieves overall structural stability and functional integration of the liquid metering device. The control valve assembly provides flow control, while the quick-connect assembly and check valve head enable safe and convenient connection and disconnection.

[0010] In a preferred example, the present invention can be further configured as follows: a joint is provided at the top end of the joint tube for connecting to the mouth of the liquid filling bottle, the joint tube is quickly connected to the fixed sleeve to achieve a detachable connection between the liquid filling bottle and the liquid outlet end tube, a needle is fixedly installed on the inner side of the joint, and a plurality of axial through holes are opened on the surface of the needle.

[0011] Specifically, by providing a connection interface at the top end of the joint pipe and combining the detachability of the quick-connect structure, quick connection and safe locking between the liquid filling bottle and the liquid outlet end pipe are achieved.

[0012] In a preferred embodiment, the present invention can be further configured as follows: the surface of the valve core body is rotatably sleeved on the inner side of the joint pipe via a ball sleeve, the bottom end of the joint pipe is provided with a valve hole, the valve ring is in sliding contact with the surface of the valve hole, and the return spring is in a stretched state; Specifically, the permanent magnet magnetically attracts the magnetic ball to cause the valve core body to tilt, that is, the valve ring separates from the bottom surface of the valve hole to open, and stretches the reset spring; when the stop valve head is separated from the quick-connect sleeve, the magnetic ball is separated from the magnetic attraction, and the valve core body is reset by the elastic recovery of the reset spring, that is, the valve hole is re-sealed by the valve ring.

[0013] In a preferred example, the present invention can be further configured as follows: the outer periphery of the ball tube seat is spherical, and the liquid outlet tube is rotatably sleeved on the surface of the ball tube seat to adjust the direction of the liquid outlet tube port.

[0014] Specifically, the shape of the tube seat is designed to be a spherical structure, and the liquid outlet end tube is rotated to cooperate with the spherical structure, so that the liquid outlet direction can be flexibly adjusted.

[0015] In a preferred example, the present invention can be further configured as follows: a valve hole is opened on the surface of the joint pipe, and the valve hole is used to abut against the surface of the lock ball to achieve connection locking between the fixed sleeve and the joint pipe.

[0016] Specifically, by setting a valve hole that cooperates with the locking ball on the surface of the joint pipe, the quick connection mechanism can be automatically engaged and locked during the connection process, thereby ensuring the stability of the connection state, avoiding accidental disconnection or loosening, and improving the operating stability and service life of the device.

[0017] In a preferred embodiment, the present invention can be further configured as follows: a first spring is fixedly mounted on the surface of the fixed sleeve, and the top end of the first spring is connected to the bottom surface of the locking sleeve, so as to push the locking sleeve to move upward; Specifically, when the joint pipe is inserted into the fixed sleeve seat, the locking sleeve is manually pulled down to break away from the contact with the locking bead, so that the locking bead radially retracts to accommodate the joint pipe; after the joint pipe is inserted, the first spring pushes the locking sleeve upward to resume contact with the surface of the locking bead, so that the locking bead is radially guided into contact with the valve hole on the surface of the joint pipe, thereby achieving locking of the fixed sleeve seat and the joint pipe.

[0018] In a preferred example, the present invention can be further configured as follows: the number of the inclined grooves on the valve seat surface and the linear grooves on the turntable surface are the same as the number of valve discs and correspond one to one, and the inclined grooves and the linear grooves are arranged in mutually staggered directions.

[0019] Specifically, the number of inclined chutes and linear chutes corresponds to the number of valve discs, so that each valve disc forms a regular movement when the turntable rotates, realizing controllable, segmented flow regulation or on-off control.

[0020] In a preferred embodiment of the present invention, the sealing strips can be further configured such that the sealing strips slide against the surfaces of the valve discs and are arranged radially to seal the joints between adjacent valve discs. The sealing strips and valve discs slide together to form a multi-point seal, ensuring a tight seal when the flow channel is closed and preventing liquid leakage.

[0021] The beneficial effects achieved by the present invention are: 1. The present invention utilizes a rotating disc, valve flaps, and their associated inclined and linear chute structures to create a control method based on deflection and sliding motion. As the disc rotates, the valve flaps, constrained by the inclined and linear chute structures, deflect synchronously, opening and closing the flaps one by one. This structure enables smoother and more precise liquid flow regulation, providing excellent controllability and sealing, significantly improving the control accuracy and reliability of the flow controller.

[0022] 2. In this invention, the quick-connect assembly achieves rapid insertion, automatic locking, and convenient removal of the connector tube from the check valve head through the sliding and elastic fit between the locking sleeve, locking bead, and fixed sleeve. The user simply presses down or releases the locking sleeve to connect or disconnect, requiring no tools, ensuring quick, safe, and reliable operation. This structure significantly improves installation efficiency and user experience, making it ideal for frequent bottle replacements.

[0023] 3. In this invention, the valve core is mounted within the check valve head. Under the magnetic force of the permanent magnet, the built-in magnetic ball generates a deflection force, causing the valve core to deflect and open the valve orifice. When disconnected, the magnetic force disappears, and the elastic restoring force of the return spring automatically returns the valve core to its original position, closing the valve orifice. This structure requires no power or external control, relying entirely on physical magnetic attraction and elastic return to achieve automated opening and closing. This ensures operational stability and immediate sealing of liquid control, significantly enhancing the system's intelligence and safety. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0027] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0028] The following describes the liquid metering devices provided by some embodiments of the present invention with reference to the accompanying drawings.

[0029] Combine Figures 1-7 As shown, the liquid metering device provided by the present invention includes a bracket 100 , a control valve group 200 , a quick-connect sleeve 300 and a check valve head 400 .

[0030] The surface of the bracket 100 is fixedly mounted with a joint seat 110 and a ball tube seat 121. The outer periphery of the ball tube seat 121 is spherical, and the surface of the liquid outlet pipe 120 is movably sleeved. The liquid outlet pipe 120 can adjust the direction of the liquid outlet port by rotating with the ball tube seat 121.

[0031] The control valve assembly 200 is fixedly mounted on the surface of the bracket 100 , and its upper and lower ends are respectively connected to the bottom end of the connector seat 110 and the top surface of the ball tube seat 121 , thereby forming a liquid flow path.

[0032] The control valve assembly 200 includes a valve seat 210, a rotary disk 220, and several valve flaps 230. The rotary disk 220 is rotatably mounted on the inner side of the valve seat 210. A rotating lug 222 is fixedly connected to the surface of the rotary disk 220. The rotating lug 222 can be connected to a control lever. Manual operation of the control lever links the rotating lug 222 and the rotary disk 220 to deflect movement for transmission or positioning. A sealing strip 221 is fixedly mounted on the inner side of the rotary disk 220. The sealing strip 221 is arranged radially and slides against the top surfaces of the multiple valve flaps 230, providing a sealing seal.

[0033] Multiple valve flaps 230 are evenly distributed circumferentially between the rotating disk 220 and the valve seat 210, and are provided with sliding protrusions 232 and sliding pins 231 on their upper and lower surfaces, respectively. The sliding protrusions 232 slide into linear grooves 223 provided on the inner side of the rotating disk 220, while the sliding pins 231 slide into inclined grooves 211 provided on the inner side of the valve seat 210. The linear grooves 223 and inclined grooves 211 are identical in number to the number of valve flaps 230, corresponding one to one, and arranged in an interlaced pattern. The deflection of the rotating disk 220, guided by the relative motion of the inclined grooves 211 and sliding pins 231, drives the valve flaps 230 to tilt open or close, achieving flow regulation or quantitative control.

[0034] The quick-connect assembly 300 is mounted on the top of the connector base 110 and is used to quickly connect and disconnect the liquid bottle and the liquid metering device. The quick-connect assembly 300 includes a fixed sleeve 310, a locking sleeve 320, and several locking beads 330. The locking sleeve 320 slides over the outside of the fixed sleeve 310 and is connected to the fixed sleeve 310 via a first spring 321. The top of the first spring 321 is connected to the bottom of the locking sleeve 320, and its elastic action pushes the locking sleeve 320 upward.

[0035] The locking ball 330 is movably mounted on the surface of the fixed sleeve 310 and slidably abuts the inner side of the locking sleeve 320. When the locking sleeve 320 is pulled down until it is out of contact with the locking ball 330, the locking ball 330 can be radially retracted, allowing the joint pipe 410 to be inserted into the fixed sleeve 310. After insertion, the locking sleeve 320, urged by the first spring 321, rebounds to its initial position, restoring contact with the locking ball 330. This allows the locking ball 330 to be radially guided into contact with the valve hole 412 on the surface of the joint pipe 410, thereby achieving locking.

[0036] The check valve head 400 comprises a joint tube 410 and a valve core 420 rotatably mounted therein. The top of the joint tube 410 is provided with a joint 411 for connection to the mouth of a liquid filling bottle. The bottom of the joint tube 410 is provided with a valve hole 412, which mechanically engages and locks the locking ball 330. A needle 413 is fixedly mounted on the inside of the joint 411. The needle 413 has several axially extending through-holes formed on its surface to accelerate the entry of liquid.

[0037] The valve core 420 is rotatably connected to the inner side of the joint pipe 410 via a ball socket 423. A magnetic ball 421 and a valve ring 422 are mounted on the surface of the valve core 420. A return spring 424 is positioned in a stretched position between the valve core 420 and the joint pipe 410. When the check valve head 400 is inserted into the quick-connect assembly 300 and locked, the permanent magnet 311 fixed to the inner side of the fixed sleeve 310 attracts the magnetic ball 421, generating a deflecting torque, thereby driving the valve core 420 to tilt, causing the valve ring 422 to disengage from the valve hole 412, thereby achieving an open state.

[0038] When disassembly is required, the lock sleeve 320 is pulled down to release the locking state, the check valve head 400 is pulled out, the attraction of the permanent magnet 311 to the magnetic ball 421 disappears, the return spring 424 restores its initial deformation, pushes the valve core body 420 back to its original position, and the valve ring 422 re-fits the valve hole 412, automatically closing the liquid outlet channel to prevent leakage.

[0039] Through the above-mentioned structure and matching method, the present invention not only realizes the rapid installation and disassembly of the liquid bottle, but also ensures the automatic control and sealing of the liquid during the connection process, greatly improving the convenience of use and system safety.

[0040] The working principle and use process of the present invention: 1. Quick connection and locking principle: The quick connection and removal of the liquid bottle and the device can be achieved through the structural cooperation of the quick connection set 300 and the check valve head 400.

[0041] When the check valve head 400 is inserted into the fixed sleeve seat 310, the lock sleeve 320 is manually pulled down to retract the lock ball 330; after the insertion is completed, the first spring 321 pushes the lock sleeve to rebound, and the lock ball is introduced into the valve hole 412 on the joint pipe 410 to achieve locking.

[0042] 2. Automatic Opening and Closing Control Principle: After insertion, the permanent magnet 311 within the quick-connect assembly attracts the magnetic ball 421 on the valve core 420, causing it to deflect, forcing the valve ring 422 away from the valve hole 412, automatically opening the valve and allowing liquid to flow out. When the quick-connect assembly is removed, the magnetic force disappears, and the return spring 424 automatically resets the valve core, closing the valve hole 412 and preventing liquid leakage.

[0043] 3. Flow Control Principle: When liquid flows through the control valve assembly 200, the rotary disk 220 cooperates with the multiple valve flaps 230. The sliding movement of the sliding pin 231 and the sliding protrusion 232 in the inclined slide groove 211 and the linear slide groove 223 causes the valve flaps to open and close, thereby accurately adjusting or quantitatively controlling the liquid output.

In this specification, illustrative uses of these terms do not necessarily refer to the same embodiment or example.
