Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste ink tank, and in particular to a waste liquid container. BACKGROUND

[0002] An inkjet printer is usually provided with a waste liquid container for collecting waste ink generated by cleaning a print head. The waste liquid container is filled with an absorbent material. When the waste liquid enters the waste liquid container, it will be adsorbed by the absorbent material under the action of capillary force and migrate between different absorbent material blocks. Finally, the waste liquid reaches an absorption steady state. It takes a certain amount of time for all the absorbent material blocks in the waste ink container to reach the absorption steady state.

[0003] To cope with a large amount of single liquid discharge injected in the vertical direction, a waste ink container with a small depth size is internally provided with a cavity not filled with absorbent material. The container is provided with a guide inlet above the cavity. The waste liquid is first stored in the cavity through the guide inlet and can be fully absorbed by the absorbent material after a period of time. During the liquid discharge process, the waste liquid in the cavity is always in a fluctuating state and is easy to splash out of the guide inlet and cause pollution. CONTENT OF THE UTILITY MODEL

[0004] Embodiments of the present application provide a waste liquid container, which aims to suppress waste liquid fluctuation and prevent waste liquid from splashing out.

[0005] Embodiments of the present application provide a waste liquid container, which includes a hollow shell, an absorption part formed by an absorbent material is arranged in the shell, the absorption part is partially hollowed out on one side in an inverse plumb direction to form a distribution cavity, and a guide inlet is arranged on the shell and communicates with the distribution cavity.

[0006] The distribution cavity is provided with a main interval and a plurality of extension intervals formed by outward expansion of a peripheral wall of the main interval. The main interval extends along a first direction, and the plurality of extension intervals are arranged at intervals in the first direction. The first direction has a plumb direction component.

[0007] The extension interval is provided with an absorption top wall and an absorption peripheral wall formed by the absorbent material. The absorption top wall is continuous with an upper edge of the absorption peripheral wall.

[0008] In a possible design, the extension interval is arranged on an outer side of the main interval outwardly expanded along a second direction.

[0009] The second direction intersects the first direction.

[0010] In a possible design, a size difference between the extension interval and the main interval in the second direction is greater than twice an interval between two adjacent extension intervals in the first direction.

[0011] In a possible design, the extension interval has a size in the second direction that is greater than a size of the absorption portion in the first direction.

[0012] In a possible design, the main interval penetrates through the absorption portion along the first direction.

[0013] In a possible design, the absorption portion includes a plurality of first absorption portions and a plurality of second absorption portions that are sequentially stacked along the first direction.

[0014] The first absorption portion is provided with a first penetration portion, the second absorption portion is provided with a second penetration portion, and the plurality of first penetration portions and the plurality of second penetration portions are joined to form the distribution cavity.

[0015] The absorption top wall is located on the first absorption portion, and the absorption peripheral wall is located on the second absorption portion.

[0016] In a possible design, as viewed along the first direction, the first penetration portion is located inside the second penetration portion, and an edge of the first penetration portion does not overlap an edge of the second penetration portion.

[0017] In a possible design, the first penetration portion has a size L1 in the second direction, the second penetration portion has a size L2 in the second direction, and the first absorption portion has a size D1 in the first direction.

[0018] L1, L2 and D1 satisfy: L2-L1≥2D1.

[0019] In a possible design, the first penetration portion and the second penetration portion are both rectangular through holes, and the second direction is a length direction or a width direction of the second penetration portion.

[0020] In a possible design, the first penetration portion and the second penetration portion are both coaxially arranged circular through holes, and the second direction is a direction parallel to a radial direction of the second penetration portion.

[0021] In the embodiments of the present application, the extension interval is introduced to expand the surface area of the distribution cavity, so as to improve the absorption efficiency of the waste liquid. During the liquid discharge process, as the liquid level in the distribution cavity rises, the fluctuating upper waste liquid will flow into different extension intervals, impact the absorption peripheral wall and the absorption top wall that have adsorption capacity, cause kinetic energy loss of the waste liquid and make the waste liquid be quickly absorbed, thereby effectively inhibiting the fluctuation of the waste liquid.

[0022] In addition, in the case that the discharge amount and the adsorption saturation degree of the absorption material are different, the plurality of extension intervals can effectively inhibit the fluctuation of the waste liquid during the liquid discharge process, thereby preventing the waste liquid from splashing out of the waste liquid container and causing pollution due to the fluctuation.

[0023] Especially for the waste liquid container with small depth size and liquid discharge from the top, the introduction of the distribution cavity with multiple extension intervals can greatly reduce the risk of waste liquid spilling into the inlet.

[0024] It should be understood that the foregoing general description and the following detailed description are only exemplary and are not limiting to the present application. BRIEF DESCRIPTION OF DRAWINGS

[0059] The embodiment provides an image forming device, which is a multifunctional image forming device with functions of printing, copying, scanning, faxing and the like. The image forming device comprises a device body and a waste liquid container mounted on the device body, and the waste liquid container can accommodate waste ink discharged from the device body.

[0060] Specifically, the device body is provided with a receiving cavity, and the waste liquid container is mounted in the receiving cavity. The device body is also provided with a first electrical connection part located in the receiving cavity, an ink discharge part and a positioning protrusion. The first electrical connection part is used for electrical connection with a second electrical connection part of the waste liquid container, so that a chip on the waste liquid container can communicate with a control part of the device body, to ensure that the waste liquid container is installed in place, and to confirm whether the model of the installed waste liquid container is accurate. The ink discharge part is correspondingly provided with the guide part of the waste liquid container, so that the waste liquid in the device body can flow into the waste liquid container along the ink discharge part and the guide part. The positioning protrusion is used for detachable cooperation with a limiting groove of the waste liquid container, so as to fix the waste liquid container in the receiving cavity. Moreover, through the detachable cooperation of the positioning protrusion and the limiting groove, the waste liquid container is also convenient to disassemble from the device body, so as to facilitate the replacement of the waste liquid container.

[0061] The specific structure of the waste liquid container will be described in detail below with reference to the drawings.

[0062] As shown in Figure 1 and Figure 2 , it is a structural schematic diagram of the waste liquid container 1, please refer to Figure 1 and Figure 2 , the waste liquid container 1 comprises a hollow shell 11, the shell 11 comprises a detachable top cover 111 and a bottom shell 112, the top cover 111 and the bottom shell 112 are connected to form a receiving cavity for accommodating the absorbing part (not shown in the figure).

[0063] Among them, Figure 3 , it is an enlarged view of A part in Figure 2 , please refer to Figure 2 and Figure 3 , the bottom shell 112 is provided with a clamping part 112a, and the top cover 111 is provided with a matching part 111a, which are clamped and matched through the clamping part 112a and the matching part 111a, to realize the connection of the top cover 111 and the bottom shell 112.

[0064] Specifically, the clamping portion 112a can be a protrusion protruding outward along the outer side wall of the bottom shell 112, and the matching portion 111a can be a matching hole or a groove. When the top cover 111 is connected with the bottom shell 112, the clamping portion 112a can be inserted into the matching portion 111a to limit the separation of the clamping portion 112a and the matching portion 111a.

[0065] More specifically, the clamping portion 112a is located on the two oppositely arranged outer side walls of the bottom shell 112, and the matching portion 111a is correspondingly arranged at a position matched with the position of the clamping portion 112a to ensure the stable connection of the top cover 111 and the bottom shell 112. Alternatively, the clamping portion 112a is arranged on the outer side wall around the periphery of the bottom shell 112, and the matching portion 111a is correspondingly arranged at a position matched with the position of the clamping portion 112a to improve the reliability of the connection of the top cover 111 and the bottom shell 112.

[0066] Please continue to refer to Figure 1 and Figure 2 The bottom shell 112 is provided with a taking portion 115 away from the device body, which facilitates the user to install or dismount the waste liquid container 1 through the taking portion 115. The bottom of the bottom shell 112 is provided with a limiting groove 112b, which can be matched with the positioning protrusion of the device body when the waste liquid container 1 is installed on the device body, so as to fix the waste liquid container 1 on the device body.

[0067] As Figure 4 shown is a schematic view of part of the structure of the waste liquid container 1 (the top cover 111 is removed), please refer to Figure 2 and Figure 4 The bottom shell 112 is provided with a second electrical connection portion 13 close to the device body, which can be electrically connected with the first electrical connection portion of the device body when the waste liquid container 1 is installed on the device body, so that the waste liquid container 1 can communicate with the control portion of the device body, ensuring that the waste liquid container 1 is installed in place and ensuring that the model of the waste liquid container 1 is installed accurately.

[0068] The second electrical connection portion 13 is a chip.

[0069] As Figure 5 shown is a cross-sectional view of the shell 11, please refer to Figure 2 , Figure 4 and Figure 5 The shell 11 is provided with an absorbing portion 12 formed of absorbing material, the absorbing portion 12 is partially hollowed out to form a distribution cavity 121 on one side of the inverse plumb, and the shell 11 is provided with a guide-in portion 113 in communication with the distribution cavity 121.

[0070] Specifically, the introduction part 113 is an opening structure provided through the top cover 111. After the waste liquid container 1 is installed to the equipment body, the introduction part 113 is arranged corresponding to the ink discharging part of the equipment body. The waste liquid in the equipment body can flow to the distribution cavity 121 along the ink discharging part and the introduction part 113, and then be absorbed by the absorption part 12 located at the outer periphery of the distribution cavity 121 to store the waste ink.

[0071] The absorption part 12 can be a component with water absorption such as sponge, non-woven fabric, etc. Alternatively, the absorption part 12 can also be made of polyurethane or other materials with water absorption. Alternatively, the absorption part 12 can also be made of other materials with water absorption, which can be set according to actual conditions, and is not limited in the embodiment.

[0072] After the waste liquid container 1 is installed in place, the ink discharging part, the introduction part 113 and the distribution cavity 121 are aligned along the plumb direction, that is, the introduction part 113 is opened upward along the plumb direction, which can reduce the resistance when the waste liquid is introduced, so that the waste liquid can flow smoothly into the distribution cavity 121.

[0073] Please continue to refer to Figure 4 and Figure 5 The distribution cavity 121 is provided with a main interval 121a and a plurality of extension intervals 121b formed by outward expansion of the peripheral wall of the main interval 121a. The main interval 121a extends along the first direction X, and the plurality of extension intervals 121b are arranged at intervals in the first direction X, and the first direction X has a plumb direction component. The extension interval 121b has an absorption top wall 121b1 and an absorption peripheral wall 121b2 formed by surrounding the absorption material, and the upper edges of the absorption top wall 121b1 and the absorption peripheral wall 121b2 are continuous.

[0074] In the embodiment, the introduction of the extension interval 121b can expand the surface area of the distribution cavity 121 to improve the absorption efficiency of the waste liquid. During the liquid discharge process, the fluctuating upper waste liquid will flow into different extension intervals 121b as the liquid level in the distribution cavity 121 rises, impact the absorption peripheral wall 121b2 and the absorption top wall 121b1 with adsorption capacity, cause the kinetic energy of the waste liquid to be lost and be quickly absorbed, thereby effectively suppressing the fluctuation of the waste liquid.

[0075] In addition, in the case that the amount of liquid discharged and the adsorption saturation degree of the absorption material are different, the plurality of extension intervals 121b can effectively suppress the fluctuation of the waste liquid during the liquid discharge process, thereby preventing the waste liquid from splashing out of the waste liquid container 1 and causing pollution.

[0076] In addition, the plurality of extension intervals 121b are arranged at intervals in the first direction X, and the plurality of extension intervals 121b all have the absorption peripheral wall 121b2 and the absorption top wall 121b1, and the absorption material exists on each side and top surface of the extension interval 121b. For the waste liquid fluctuating in each horizontal direction, it has the dual effects of kinetic energy consumption and adsorption, and thus has a good inhibitory effect on the fluctuation of the waste liquid.

[0077] Especially for the waste ink container with small depth size and liquid discharge from the top, introducing the distribution cavity 121 with multiple extension intervals 121b can greatly reduce the risk of waste liquid splashing out of the introduction part 113.

[0078] Please continue to refer to Figure 5 The extension interval 121b is arranged outside the main interval 121a extending outward along the second direction Y, and the second direction Y intersects the first direction X. That is, the extension interval 121b is an interval further extending outward along the second direction Y from the main interval 121a, which enlarges the contact area of the extension interval 121b with the waste liquid and improves the absorption efficiency of the absorption part 12 to the waste liquid.

[0079] Specifically, in some embodiments, the second direction Y is substantially perpendicular to the first direction X.

[0080] In some embodiments, the difference in size of the extension interval 121b in the second direction Y is greater than twice the interval of the adjacent two extension intervals 121b in the first direction X, so as to enlarge the surface area and volume of the extension interval 121b, thereby further improving the suppression effect on the waste liquid fluctuation.

[0081] In some embodiments, the size of the extension interval 121b in the second direction Y is greater than the size of the absorption part 12 in the first direction X, so as to enlarge the volume of the extension interval 121b and improve the suppression effect on the waste liquid fluctuation.

[0082] In addition, the size of the extension interval 121b in the second direction Y is greater than the size of the absorption part 12 in the first direction X, that is, the size of the absorption part 12 in the second direction Y is greater than the size of the absorption part 12 in the first direction X, so that the absorption part 12 can effectively suppress the waste liquid fluctuation even if it is applied to a flat box-shaped waste liquid container 1.

[0083] Please continue to refer to Figure 5 The main interval 121a penetrates the absorption part 12 along the first direction X, so as to enlarge the depth size of the distribution cavity 121, increase the volume of the distribution cavity 121, and enable the waste liquid container 1 to cope with a larger amount of single liquid discharge.

[0084] Figure 6 As shown in the cross-sectional view of the shell 11, the absorption part 12 includes a plurality of first absorption parts 122 and a plurality of second absorption parts 123 arranged in sequence along the first direction X. Specifically, a second absorption part 123 is arranged between two adjacent first absorption parts 122, and a first absorption part 122 is arranged between two adjacent second absorption parts 123, and the first absorption part 122 and the second absorption part 123 can correspond to one or more pieces of stacked absorption material.

[0085] The first absorbing portion 122 is provided with a first through portion 122a, and the second absorbing portion 123 is provided with a second through portion 123a. The first through portion 122a and the second through portion 123a are connected to form a distribution cavity 121. That is, the first through portion 122a is a through hole penetrating the first absorbing portion 122 along the first direction X, and the second through portion 123a is a through hole penetrating the second absorbing portion 123 along the first direction X, so that the first through portion 122a and the second through portion 123a are connected in sequence to form the distribution cavity 121 penetrating the entire absorbing portion 12.

[0086] Please continue to refer to Figure 6 When viewed along the first direction X, the first through portion 122a is located inside the second through portion 123a, and the edge of the first through portion 122a does not overlap the edge of the second through portion 123a. That is, the size of the second through portion 123a in the second direction Y is greater than the size of the first through portion 122a in the second direction Y, and the second through portion 123a is outwardly expanded along the second direction Y compared with the first through portion 122a. The extension interval 121b is the area of the second through portion 123a outwardly expanded compared with the first through portion 122a.

[0087] That is, the second through portion 123a is outwardly expanded along the second direction Y compared with the first through portion 122a, so that the second absorbing portion 123 can form the extension interval 121b relative to the recess formed by the adjacent first absorbing portion 122. The absorbing top wall 121b1 is located on the first absorbing portion 122, and the absorbing peripheral wall 121b2 is located on the second absorbing portion 123.

[0088] The embodiment forms the absorbing portion 12 by sequentially arranging the first absorbing portion 122 and the second absorbing portion 123, so that the first through portion 122a on the first absorbing portion 122 and the second through portion 123a on the second absorbing portion 123 form the distribution cavity 121. By limiting the size of the first through portion 122a and the second through portion 123a, the extension interval 121b is formed in the absorbing portion 12. Compared with machining the extension interval 121b on the overall structure of the absorbing portion 12, the processing technology is simplified.

[0089] Please continue to refer to Figure 6 The size of the first through portion 122a in the second direction Y is L1, the size of the second through portion 123a in the second direction Y is L2, the size of the first absorbing portion 122 in the first direction X is D1, and L1, L2 and D1 satisfy: L2-L1≥2D1.

[0090] By limiting L2-L1≥2D1, it is ensured that the area of the second through portion 123a outwardly expanded along the second direction Y compared with the first through portion 122a has a large enough space, the area for storing waste liquid is increased, and the suppression effect on the fluctuation of waste liquid is improved.

[0091] Please continue to refer to Figure 4 In some embodiments, the first through portion 122a and the first through portion 122a are both rectangular through holes, and the second direction Y is the length direction or the width direction of the second through portion 123a.

[0092] Alternatively, in some embodiments, the first through portion 122a and the second through portion 123a are both coaxially arranged circular through holes, and the second direction Y is a direction parallel to the radial direction of the second through portion 123a.

[0093] Still alternatively, the first through portion 122a and the second through portion 123a can be other shapes of coaxially arranged through holes, which can be set according to actual conditions, and the present embodiment is not limited herein.

[0094] Please continue to refer to Figure 2 The top cover 111 is provided with an evaporation grille 114, which can expose part of the absorption portion 12 to evaporate the moisture in the waste liquid in the absorption portion 12, so as to store more waste liquid.

[0095] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
