Description

Technical Field

[0001] This utility model belongs to the field of washing machine accessories technology, specifically relating to a multifunctional ink cartridge assembly. Background Technology

[0002] Currently, washing machines on the market typically come with a dispensing box, which is a movable box without a liquid storage function. The dispensing box contains one or more ink cartridges, which have a liquid storage function. Users can refill the ink cartridges multiple times, making it convenient to use. A patent with publication number CN214493997U discloses a novel soft-pack structure, including a soft pack and a one-way valve. One end of the soft pack has a liquid outlet, which houses the one-way valve. It also includes a shell and an interface. The shell has an internal cavity with an opening at one end for inserting the soft pack. The liquid outlet of the soft pack is detachably connected to one end of the interface, and the interface is detachably connected to the opening at the shell. The soft pack is placed within the cavity formed by the shell and the interface. This drawer-type soft pack, using a soft pack and a one-way valve, can be directly used on the washing machine, is convenient, and does not occupy external space. However, the one-way valve placement of existing ink cartridges is unreasonable, resulting in significant liquid residue after extraction; the ink cartridges lack separate covers and vent valves, making detergent replacement inconvenient and resulting in poor liquid extraction efficiency. Furthermore, the lack of ink level detection in the ink cartridge results in a poor user experience. Therefore, a multi-functional ink cartridge assembly needs to be designed to overcome these difficulties. Summary of the Invention

[0003] This invention addresses the problems existing in the prior art by designing a multifunctional ink cartridge assembly. The invention facilitates the replacement of detergent through a sealing component, and detergent residue is not easily left behind; the liquid level is detected through a float component, resulting in a better user experience.

[0004] The objective of this invention is achieved through the following technical solution: a multifunctional ink cartridge assembly, comprising an ink cartridge body, the ink cartridge body including a front cover and a rear cover; the front cover has a liquid extraction channel extending into the ink cartridge body, and a one-way valve assembly and a filter assembly are respectively provided in the liquid extraction channel, the one-way valve assembly being located near the inlet of the liquid extraction channel, and the filter assembly being located near the end of the liquid extraction channel; the front cover has a float assembly for liquid level detection, and the open end of the front cover has a sealing assembly for sealing the ink cartridge body; the sealing assembly includes a vent valve.

[0005] Preferably, the liquid extraction channel is provided with a limiting step, one end of which is equipped with a one-way valve assembly, and the other end of which is equipped with a filter assembly.

[0006] Preferably, the one-way valve assembly includes a valve base, a valve body, a spring, and a valve core; the valve base and the valve body are snap-fitted together, the valve base is tightly fitted in the liquid extraction channel, and the valve base is fitted with a limiting step; the valve core is slidably installed in the valve body, and a spring is provided between the valve core and the valve base.

[0007] Preferably, both the valve base and the valve body are hollow, and the valve core is provided with a first sealing element; in the default state, the first sealing element abuts against the inner wall of the valve body; the outer wall of the valve body is provided with a second sealing element, which is disposed between the valve body and the liquid extraction channel.

[0008] Preferably, the filter assembly includes a filter element body and a third seal; the filter element body and the end of the liquid extraction channel are tightly connected, and a third seal is provided between the filter element body and the inner wall of the liquid extraction channel for sealing.

[0009] When the ink cartridge is removed from the dispensing tray of the washing machine, the valve core, under the action of a spring, presses against the inner wall of the valve body, thus closing the one-way valve assembly. Detergent inside the ink cartridge will not flow out of the extraction channel, allowing the user to easily replace the detergent simply by opening the sealing assembly. When the ink cartridge is installed into the dispensing tray, a protrusion inside the tray presses against the valve core, opening the one-way valve assembly. When the washing machine's pump operates, it extracts the detergent from the ink cartridge. A filter element is installed at the end of the extraction channel of the ink cartridge to prevent impurities in the detergent from escaping through the extraction channel, resulting in better overall cleaning performance.

[0010] Preferably, the front cover and rear cover of the ink cartridge are formed into the ink cartridge body by high-frequency welding, and an insert is provided between the front cover and the rear cover; a column is provided on the front cover, and the column extends along the axial direction of the ink cartridge body; the column is forked in the middle, and the outer diameter of the column gradually increases from the root to the end; a float assembly is sleeved on the column, and the float assembly can rotate relative to the column; a magnet is installed on the float assembly, and a magnetic switch is provided on the outside of the ink cartridge body facing the float assembly; an electrical signal is generated when the magnet approaches the magnetic switch.

[0011] The ink cartridge body is typically installed horizontally inside the detergent dispenser. When the user fills the cartridge with detergent, the liquid level is usually high. The float assembly, influenced by the buoyancy of the liquid, rotates relative to a pillar on the inner wall of the cartridge's front cover. The magnet inside the float assembly is far from the magnetic switch on the outside of the cartridge body, so the magnetic switch is off and no electrical signal is generated. When detergent is removed from the cartridge, the float assembly descends with the liquid level, triggering the magnetic switch. This activates the magnetic switch, sending an electrical signal to the washing machine's control panel, thus achieving the liquid level detection function.

[0012] Preferably, the open end of the ink cartridge front cover is provided with a sealing assembly threadedly connected thereto. The sealing assembly includes a sealing cap, an annular sealing ring, and a vent valve. A threaded circular post is provided on the open end of the ink cartridge front cover, and the sealing cap is threadedly connected to the threaded circular post. An annular sealing ring is tightly fitted inside the sealing cap, and the outer contour of the annular sealing ring is adapted to the outer contour of the sealing cap. When the sealing cap is installed on the threaded circular post, the annular sealing ring abuts against the end of the threaded circular post. A vent valve is installed on the sealing cap.

[0013] Preferably, the threaded cylindrical column extends into the ink cartridge body along its axial direction. The inner wall of the threaded cylindrical column has a first extension extending radially, and the first extension has a marking. The sealing cover has a mounting through hole for installing a vent valve, and several evenly distributed vent holes are arranged around the mounting through hole. In the default state, the diaphragm of the vent valve is attached to the vent hole. The sealing cover is cylindrical, and the mounting through hole is eccentrically positioned with respect to the sealing cover. The outer layer of the threaded cylindrical column has a limiting rib, and the outer wall of the sealing cover has a clearance groove. When the clearance groove on the sealing cover is engaged with the limiting rib, the vent valve is positioned away from the limiting rib.

[0014] The sealing cap is connected to the cartridge body via a threaded cylindrical thread, facilitating easy assembly and disassembly. The mounting through-hole is offset from the sealing cap, allowing for an offset of the vent valve on the mounting through-hole. A clearance groove and a limiting rib limit the rotation angle of the sealing cap. When the sealing cap is tightened to the cartridge body, the clearance groove abuts against the limiting rib, which is located near the bottom of the cartridge body. At this time, the vent valve is positioned away from the limiting rib and near the top of the cartridge body, ensuring continuous ventilation during detergent extraction. During extraction, external air enters the cartridge body through the vent valve, balancing the internal pressure and making detergent extraction smoother. An annular sealing ring further enhances the cartridge body's sealing performance. When adding detergent, the cartridge body is placed vertically; a marking on the first extension indicates the maximum detergent capacity.

[0015] Preferably, the sealing assembly includes a flip cover, a vent valve, and a rectangular seal; the flip cover is mounted on the upper surface of the ink cartridge front cover and is rotatably connected to the ink cartridge front cover; a rectangular seal is provided on the lower surface of the flip cover, and when the flip cover is fitted with the ink cartridge front cover, the rectangular seal is fitted onto the ink cartridge front cover; a second extension is provided on the open end of the ink cartridge front cover, extending radially therefrom, and the second extension is marked; a vent valve is provided on the flip cover, and a guide handle groove is provided on the open end of the ink cartridge front cover, the guide handle groove being inclined to the ink cartridge front cover.

[0016] This cartridge uses a flip-top design, with the flip-top rotating relative to the cartridge body. When the flip-top is in contact with the cartridge body, it is sealed by a rectangular seal, keeping the cartridge body closed. To add detergent, open the flip-top and add detergent through the guide handle groove, allowing it to flow smoothly into the cartridge body. With the cartridge body lying flat while adding detergent, a marking on the second extension indicates the maximum detergent capacity, making it easy to know.

[0017] Compared with the prior art, the present invention has the following advantages: 1. The sealing component on the ink cartridge body can be easily opened and closed, facilitating the replacement of detergent; 2. A float assembly is set inside the ink cartridge body to facilitate the detection of the liquid level inside the ink cartridge body; 3. By setting a filter assembly, impurities in the detergent are prevented from flowing out of the ink cartridge body; 4. By setting a vent valve, the pressure inside and outside the ink cartridge body is balanced during the liquid extraction process, making the liquid extraction process smoother.

The valve core 34 is slidably installed inside the valve body 32, and a spring 33 is provided between the valve core 34 and the valve base 31. Both the valve base 31 and the valve body 32 are hollow. A first sealing element 35 is provided on the valve core 34. In the default state, the first sealing element 35 abuts against the inner wall of the valve body 32. A second sealing element 36 is provided on the outer wall of the valve body 32, and the second sealing element 36 is disposed between the valve body 32 and the liquid extraction channel 2. The filter assembly 4 includes a filter element body 41 and a third seal 42; the filter element body 41 and the end of the liquid extraction channel 2 are tightly connected, and a third seal 42 for sealing is provided between the filter element body 41 and the inner wall of the liquid extraction channel 2.

[0021] The ink cartridge front cover 101 and ink cartridge rear cover 102 are formed into the ink cartridge body 1 by high-frequency welding. An insert 103 is provided between the ink cartridge front cover 101 and ink cartridge rear cover 102. A column 8 is provided on the ink cartridge front cover 101, and the column 8 extends along the axial direction of the ink cartridge body 1. The column 8 is forked in the middle, and the outer diameter of the column 8 gradually increases from the root of the column 8 to the end of the column 8. A float assembly 5 is sleeved on the column 8, and the float assembly 5 can rotate relative to the column 8. A magnet 51 is installed on the float assembly 5, and a magnetic switch 52 is provided on the outside of the ink cartridge body 1 facing the float assembly 5. When the magnet 51 is close to the magnetic switch 52, it can generate an electrical signal. The ink cartridge front cover 101 has a sealing assembly 6 threadedly connected to its open end. The sealing assembly 6 includes a sealing cap 62, an annular sealing ring 63, and a vent valve 61. A threaded circular post 64 is provided on the open end of the ink cartridge front cover 101, and the sealing cap 62 is threadedly connected to the threaded circular post 64. An annular sealing ring 63 is tightly fitted inside the sealing cap 62, and the outer contour of the annular sealing ring 63 is adapted to the outer contour of the sealing cap 62. When the sealing cap 62 is installed on the threaded circular post 64, the annular sealing ring 63 abuts against the end of the threaded circular post 64. A vent valve 61 is installed on the sealing cap 62. The threaded cylindrical column 64 extends into the ink cartridge body 1 along its axial direction. A first extension 65 extending radially is provided on the inner wall of the threaded cylindrical column 64, and a marking is provided on the first extension 65. The sealing cover 62 has a mounting through hole 66 for installing the vent valve 61, and several evenly distributed vent holes 67 are provided around the mounting through hole 66. In the default state, the diaphragm of the vent valve 61 is attached to the vent hole 67. The sealing cover 62 is cylindrical, and the mounting through hole 66 is eccentrically positioned with respect to the sealing cover 62. The outer layer of the threaded cylindrical column 64 has a limiting rib 68, and the outer wall of the sealing cover 62 has a clearance groove 69. When the clearance groove 69 on the sealing cover 62 is engaged with the limiting rib 68, the vent valve 61 is positioned away from the limiting rib 68.

[0022] The specific operation process of this embodiment is as follows: When the ink cartridge body 1 is removed from the dispensing box on the washing machine, the valve core 34 abuts against the inner wall of the valve body 31 under the action of the spring 33, so the one-way valve assembly 3 is in a closed state; the detergent in the ink cartridge body 1 will not flow out from the extraction channel 2, and the user can easily replace the detergent by simply opening the sealing assembly 6. When the ink cartridge body 1 is installed into the dispensing box, the protrusion in the dispensing box will squeeze the valve core 34, so the one-way valve assembly 3 is in an open state. When the extraction pump in the washing machine works, the detergent in the ink cartridge body 1 can be extracted. A filter body 41 is set at the end of the extraction channel 2 of the ink cartridge body 1, which prevents impurities in the detergent from being discharged from the extraction channel 2, resulting in a better overall cleaning effect.

[0023] The ink cartridge body 1 is typically installed horizontally inside the detergent dispenser. When the user fills the ink cartridge body 1 with detergent, the liquid level is usually high. The float assembly 5, influenced by the buoyancy of the liquid level, can rotate around the column 8 on the inner wall of the ink cartridge front cover 101. The magnet inside the float assembly 5 is far from the magnetic switch 52 on the outside of the ink cartridge body 1, so the magnetic switch 52 is off and no electrical signal is generated. When the detergent in the ink cartridge body 1 is removed, the float assembly 5 descends with the liquid level, the magnetic switch 52 is activated, and sends an electrical signal to the control panel inside the washing machine, thus achieving the liquid level detection function.

[0024] The sealing cap 62 is threadedly connected to the threaded circular post 64 on the ink cartridge body 1, facilitating disassembly and assembly. The mounting through hole 66 is eccentrically positioned with respect to the sealing cap 62, allowing the vent valve 61 on the mounting through hole 66 to also be eccentrically positioned. The rotation angle of the sealing cap 62 is limited by the recessed groove 69 and the limiting rib 68. When the sealing cap 62 is tightened onto the ink cartridge body 1, the recessed groove 69 abuts against the limiting rib 68, which is located near the bottom of the ink cartridge body 1. At this time, the vent valve 61 is positioned away from the limiting rib 68 and near the top of the ink cartridge body 1, ensuring continuous ventilation during ink extraction. During extraction, external air enters the ink cartridge body 1 through the vent valve 61, balancing the internal pressure and making the detergent extraction process smoother. The annular sealing ring 63 further enhances the sealing performance of the ink cartridge body 1. When adding detergent, the ink cartridge body 1 is placed vertically; the markings on the first extension 65 provide guidance, so that the user can clearly know the maximum amount of detergent to add.

[0025] Example 2 like Figures 8 to 9 As shown, this embodiment differs from Embodiment 1 only in that the sealing component 6 is threadedly connected to the ink cartridge body 1, while the sealing component in this embodiment uses a flip-top connection. The sealing component 6 includes a flip-top 9, a vent valve 61, and a rectangular sealing element 10; the flip-top 9 is installed on the upper end face of the ink cartridge front cover 101, and the flip-top 9 is rotatably connected to the ink cartridge front cover 101; the lower end face of the flip-top 9 is provided with a rectangular sealing element 10, and when the flip-top 9 is fitted with the ink cartridge front cover 101, the rectangular sealing element 10 is fitted onto the ink cartridge front cover 101; the open end of the ink cartridge front cover 101 is provided with a second extension 11 extending radially therefrom, and the second extension 11 is marked; the flip-top 9 is provided with a vent valve 61, and the open end of the ink cartridge front cover 101 is provided with a guide handle groove 12, and the guide handle groove 12 is inclined to the ink cartridge front cover 101.

[0026] The ink cartridge body 1 here adopts a flip-top 9-type design, and the flip-top 9 can rotate relative to the ink cartridge body 1. When the flip-top 9 is in contact with the ink cartridge body 1, it is sealed by the rectangular sealing member 10, and the ink cartridge body 1 is in a closed state. When detergent needs to be added, the flip-top 9 is opened, and the detergent is added from the guide handle groove 12, so that the detergent can flow smoothly into the ink cartridge body 1. By setting the ink cartridge body 1 flat when adding detergent, the maximum amount of detergent can be easily known through the markings on the second extension 11.

[0027] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
