Description

TECHNICAL FIELD

[0001] The utility model relates to inkjet imaging field especially relates to a ink bottle. BACKGROUND

[0002] The ink bottle is a container for storing and delivering ink, which is usually applied in inkjet imaging equipment as a supply source of ink. The ink bottle is mainly composed of a bottle body for containing ink and a bottle cap for sealing the bottle body. During use, the user installs the ink bottle into the ink supply system of the inkjet imaging equipment by unscrewing the bottle cap, and the ink flows into the equipment through the ink outlet on the bottle body. In order to prevent ink leakage, the ink outlet of the ink bottle is usually equipped with a valve core to control the flow of ink.

[0003] The existing ink bottle usually controls the opening and closing of the valve core by an elastic element. Specifically, during transportation, the action of the elastic element makes the valve core tightly closed to prevent ink leakage. When the ink bottle is installed into the inkjet imaging equipment, the air guide column in the equipment will push the valve core to move inward, overcoming the elastic force of the elastic element, and then opening the ink outlet to allow the ink to flow into the inkjet imaging equipment.

[0004] In order to ensure that ink leakage is prevented during transportation, the existing ink bottle often designs an elastic element with a large elastic force to ensure that the valve core can remain in a tightly closed state during transportation. However, although the use of an elastic element with a large elastic force effectively prevents ink leakage during transportation, the reaction force of the elastic element may cause the ink bottle to be accidentally ejected when the ink bottle is installed into the inkjet imaging equipment, thereby affecting the normal installation and use of the ink bottle and increasing the operation difficulty during ink filling.

When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements can be present. The terms "front," "back," "upper," "lower," and the like are used herein for clarity in describing the technical solutions and are not intended to limit the scope of the present application. It should be understood that the use of these terms should not limit the scope of the present application.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0047] Referring to Figures 1-2 One embodiment of the present application provides an ink bottle 1, which mainly consists of a bottle body 10, a middle cover 20, a valve core assembly 30 and an upper cover 40.

[0048] Bottle body 10

[0049] The bottle body 10 includes a bottle body 11 and a bottle mouth 12 arranged at the top of the bottle body. The bottle body 11 is internally provided with a storage chamber 13 for storing ink Figure 4 The bottle mouth 12 is in communication with the storage chamber 13, and the ink in the storage chamber 13 flows outwards through the bottle mouth 12. The bottle body 11 is designed in a substantially cylindrical shape to facilitate the storage and transportation of ink, but in other embodiments, the bottle body 11 can also be other shapes, such as a quadrangular prism or other suitable geometric shapes.

[0050] The bottle body 11 is specially designed to have a certain elastic deformation capacity. During use of the ink bottle, the bottle body 11 can be elastically deformed to adjust the volume of the storage chamber 13, ensuring smooth flow of the ink.

[0051] The bottle mouth 12 is located at the top of the bottle body 11, and the outer circumferential surface thereof is provided with an outer protrusion for cooperating with an inner protrusion of the middle cover 20 to ensure the sealing of the bottle cover.

[0052] Middle cover 20

[0053] The middle cover 20 is detachably connected to the bottle mouth 12, and can be fixed to the bottle mouth 12 by thread connection, clamping or other suitable means, or integrated with the bottle body 11. The middle cover is provided with an ink outlet 23, which has ink channels 233 and gas channels 231 separated from each other. The ink channels 233 have a first opening (not shown in the figure) close to the bottle mouth 12 in the axial direction, for the outflow of ink. The gas channels 231 have a second opening (not shown in the figure) close to the bottle mouth 12 in the axial direction, for the inflow of gas. Through this structural design, the ink bottle can ensure the flow of ink while avoiding the entry of gas into the ink bottle during ink injection and use, thereby maintaining the pressure balance inside the ink bottle. The ink channels 233 have a third opening away from the bottle mouth 12 in the axial direction, for the inflow of ink into the ink channels 233, and the gas channels 231 have a fourth opening away from the bottle mouth 12 in the axial direction, for the inflow of gas into the gas channels 231. The third opening is farther away from the bottle body in the axial direction than the fourth opening, so that the inlets of ink and gas are separated, avoiding interference between the gas and the ink inflow position.

[0054] The middle cover 20 is also provided with a plurality of clamping grooves 25 for cooperating with the edges of the positioning holes 103 of the inkjet imaging device, to ensure the stability of the ink bottle during installation and avoid accidental falling of the ink bottle due to the reaction force of the elastic element or other external forces.

[0055] In one embodiment, the middle cover 20 includes a cover portion 21, a positioning portion 22, a limiting portion 24 and a convex portion 220. The cover portion 21 is a cylindrical structure with an inner circumferential surface provided with an inner protrusion. The inner protrusion of the cover portion 21 is clamped with the outer protrusion of the bottle mouth 12 to stably assemble the middle cover 20 on the bottle body 10. The cover portion 21 ensures good sealing by clamping the outer protrusion and the inner protrusion to prevent ink leakage. In other embodiments, thread connection can also be used. In this embodiment, the outer circumference of the cover portion 21 is polygonal in shape to facilitate operation and fixation, but other shapes such as circular or other suitable geometric shapes can also be used.

[0056] The positioning portion 22 extends outwardly in the axial direction L from the top of the cover portion 21, and is used to cooperate with the positioning holes 103 on the positioning plate 101 of the inkjet imaging device 100, thereby achieving precise positioning of the ink bottle 1. In this embodiment, the cross section of the positioning portion 22 is approximately rectangular in shape, but other shapes such as a polygonal outer circumference can also be used according to actual needs.

[0057] The outer side wall of the positioning portion 22 comprises oppositely arranged first and second side walls 221 and 222. One end of the first side wall 221 is connected with one end of the second side wall 222 with a third side wall 223, and the other end of the first side wall 221 is connected with the other end of the second side wall 222 with a fourth side wall 224. Through this structure, the positioning portion 22 can achieve a more stable positioning effect, ensuring that the relative position between the ink bottle and the inkjet imaging device remains stable during the installation process. Further, the first and second side walls 221 and 222 are planar structures, and they are parallel to each other. The parallel design effectively prevents the ink bottle 1 from rotating relative to the inkjet imaging device 100 during the installation process, ensuring that the ink bottle is accurately installed and stably fixed. The third side wall 223 is an outwardly convex circular arc shape, increasing the overall stability of the positioning portion and helping to guide the smooth installation of the ink bottle into the device. The fourth side wall 224 is approximately planar, and the central portion thereof is further provided with an outwardly convex circular arc-shaped convex surface. This design helps to further enhance the positioning accuracy and the convenience of installation.

[0058] The limiting portion 24 is arranged between the cover portion 21 and the positioning portion 22, and serves to limit the depth of insertion of the positioning portion 22 into the positioning hole 103 of the inkjet imaging device. When the ink bottle 1 is installed into the inkjet imaging device 100, the upper end surface of the limiting portion 24 will be in contact with the outer surface of the device positioning plate 101 (as shown in Figure 5 The contact effect ensures that the positioning portion 22 is not inserted too deeply into the positioning hole 103, thereby preventing the ink bottle 1 from being installed too deeply or inaccurately, and ensuring the correct positioning of the ink bottle in the device. As an example, the limiting portion 24 is a cylindrical structure, and the end of the limiting portion 24 close to the bottle mouth is connected with the top of the middle cover 21. This structure design enables the limiting portion 24 to effectively limit the insertion depth of the positioning portion 22, ensuring that the ink bottle will not affect the positioning or sealing effect due to over-insertion during the installation process.

[0059] The protrusion 220 is arranged on the outer side wall of the positioning portion 22, and together with the limiting portion 24 and the positioning portion 22 forms at least one clamping groove 25. The clamping groove 25 can be used to cooperate with the edge of the positioning hole 103 on the inkjet imaging device, enhancing the bonding force between the ink bottle and the positioning plate of the inkjet imaging device, ensuring that the ink bottle is stably fixed during the installation process, and avoiding accidental ejection due to external force or reaction force. In another embodiment, the clamping groove 25 can be formed in a different way. Specifically, instead of relying on the arrangement of the protrusion 220, the clamping groove 25 is formed by arranging a recess on the outer side wall of the positioning portion 22, thereby forming at least one clamping groove 25.

[0060] In one embodiment, the convex portion 220 is substantially triangular in shape, and includes a first side 2201, a second side 2202, and a top surface 2203. The first side 2201 is located on the side of the convex portion 220 facing the limiting portion 24, and is inclined outwardly as it moves away from the limiting portion 24. The first side 2201 forms a limiting step with the outer side wall of the positioning portion 22. The limiting step prevents the ink bottle from being ejected outwardly due to reaction force or external force during installation or use, thereby enhancing the stability of the ink bottle and ensuring that it is securely fixed in the inkjet imaging device. Moreover, the first side 2201 is inclined, which serves as a guide during disassembly, making it easier to pull the ink bottle out of the inkjet imaging device.

[0061] The second side 2202 is located on the side of the convex portion 220 facing away from the limiting portion 24, and is inclined inwardly as it moves away from the limiting portion 24. The inward inclination of the second side 2202 allows the ink bottle to pass smoothly through the positioning hole 103 during installation, and guides the top surface 2203 over the edge of the positioning hole 103 during installation, ensuring that the ink bottle is accurately inserted into the clamping groove 25, thereby achieving stable positioning of the ink bottle. Preferably, the end of the second side 2202 away from the limiting portion 24 extends to the end surface of the positioning portion 22, making the installation of the ink bottle more stable and improving stability and accuracy.

[0062] The top surface 2203 is connected between the first side 2201 and the second side 2202, forming a triangular structure of the convex portion 220. Preferably, the top surface 2203 is parallel to the central axis of the middle cover 21. The parallel design of the top surface 2203 ensures that the ink bottle can pass smoothly through the positioning hole 103 during installation, and the structure of the top surface 2203 allows the edge of the positioning hole 103 to be accurately inserted into the clamping groove 25. This parallel structure design further ensures the accurate docking between the ink bottle and the inkjet imaging device 100. The angle between the first side 2201 and the central axis is greater than the angle between the second side 2203 and the central axis, so that more force is required to detach the ink bottle from the inkjet imaging device, thereby preventing the ink bottle from being easily detached from the inkjet imaging device.

[0063] In one embodiment, the number of protrusions 220 is two or more, and all protrusions 220 are arranged at intervals in the circumferential direction. The plurality of protrusions 220 are arranged at intervals on the outer side wall of the positioning portion 22 and distributed in the circumferential direction, thereby forming a plurality of clamping grooves 25 together with the limiting portion 24 and the positioning portion 22, and the existence of the plurality of clamping grooves makes the positioning of the ink bottle more stable. Preferably, the protrusions 220 are arranged on the fourth side wall 224 of the positioning portion, which is close to one side of the gas passage 231. When the ink bottle is installed on the inkjet imaging device, the gas guide column of the inkjet imaging device is in contact with the valve core after passing through the gas passage 231. By arranging the protrusions 220 on the fourth side wall 224 and close to the gas passage 231, it can help to better disperse and offset the reaction force from the elastic element during the ink filling process.

[0064] In one embodiment, two protrusions 220 are included, and the back sides of the two protrusions 220, which are opposite to each other, are located on the same plane as the first side wall and the second side wall, respectively. By designing the largest possible distance between the two protrusions 220, the force applied on the ink bottle can be effectively dispersed, and the stability and fixing effect between the ink bottle and the inkjet imaging device can be enhanced.

[0065] The protrusions 220 in the present embodiment are integrally formed with the positioning portion 22, and can also be independent parts installed on the positioning portion 22. The material of the protrusions 220 can also be a flexible material, such as rubber.

[0066] In one embodiment, the ink outlet 23 and the middle cover are in a split structure, the top of the positioning portion 22 is provided with a mounting hole 225, the ink outlet 23 includes a mounting portion 230 and an ink outlet nozzle 232, the overall shape of the mounting portion 230 matches the shape of the mounting hole 225 on the positioning portion 22, and the mounting portion 230 is installed in the mounting hole 225 on the top of the mounting portion 230. The ink outlet nozzle 232 extending outward in the axial direction L is arranged on one side of the center line of the mounting portion 230, and the ink passage 233 is arranged on the ink outlet nozzle 232. The gas passage 231 is arranged on the other side of the center line of the mounting portion 230.

[0067] In the present embodiment, the ink outlet 23 is an independent part and is arranged independently of the positioning portion 22. The ink outlet 23 is made of a soft material, such as silicone material, which can better seal the ink outlet 23, the inkjet imaging device, the middle cover 20 and the valve core assembly 30. The ink outlet 23 can also be integrally formed with the positioning portion 22.

[0068] In the present embodiment, the axial protrusion height of the ink outlet nozzle 232 is higher than the axial protrusion height of the mounting portion 230, so that the ink passage 233 is longer than the gas passage 231, which can better separate the ink passage 233 and the gas passage 231, and avoid the ink from blocking the gas passage 231 during the ink filling process. The axial heights of the ink passage 233 and the gas passage 231 can also be substantially the same.

[0069] Valve core assembly 30

[0070] The valve core assembly includes a valve core and an elastic element, the valve core is movable between a first position closing the first opening and the second opening and a second position away from the first opening and the second opening, the elastic element is used to exert an elastic force on the valve core to keep the valve core in the first position, thereby ensuring that the ink outlet of the ink bottle is in a closed state when the ink bottle is not installed, preventing ink leakage.

[0071] In an embodiment, the valve core assembly 30 further includes a valve core seat 32, the valve core seat 32 includes a circumferential wall 320, a valve core receiving portion 321 and an elastic element receiving portion 322, the circumferential wall 320 is a cylindrical wall extending in the axial direction L. The upper surface of the circumferential wall 320 is provided with a base surface 3201. The base surface 3201 seals a part of the top opening of the circumferential wall 320 in the radial direction. The circumference of the circumferential wall 320 is provided with a flange 3202. The outer diameter of the flange 3202 is greater than the outer diameter of the circumferential wall 320. The upper end surface of the flange 3202 abuts against the inside of the positioning portion 22, achieving the axial L positioning of the front end of the valve core assembly 30 relative to the middle cover 20. The outer wall of the circumferential wall 320 can also be sleeved with a sealing ring 50. The sealing ring 50 is fitted at the lower end surface close to the flange 3202.

[0072] The outer contour structure of the valve core receiving portion 321 matches the inner structure of the positioning portion 22. The valve core receiving portion 321 extends upward from the base surface 3201 of the circumferential wall 320 in the axial direction L. The valve core 31 is received in the valve core receiving portion 321 and is slidable in the axial direction L in the valve core receiving portion 321.

[0073] The elastic element receiving portion 322 includes two support walls 3221 and a connecting wall 3222. The two support walls 3221 extend in the axial direction L.

[0074] The upper ends of the two support walls 3221 are connected to the lower end of the circumferential wall 320. The two support walls 3221 form an ink flow channel for the flow of ink therebetween. The connecting wall 3222 is connected to the lower ends of the two support walls 3221. In this embodiment, the number of support walls 3221 is 2. However, more than two can be provided, in which case, multiple ink flow channels 3223 will be formed.

[0075] In one embodiment, the valve core 31 comprises a blocking part 310 and a supporting part 311. The blocking part 310 protrudes in the axial direction L towards the positioning part 22 of the middle cover 20. When the ink bottle 1 is not installed on the inkjet imaging device 100, the valve core 31 is in a state of closing the ink outlet, the upper end surface of the blocking part 310 of the valve core 31 abuts against the lower surface of the ink outlet 23, at this time the first opening and the second opening are closed. When the ink bottle 1 is installed on the inkjet imaging device 100, the valve core 31 is pushed open by the air guide column 102 of the inkjet imaging device 100, the blocking part 310 is away from the lower surface of the ink outlet 23, at this time the first opening and the second opening are opened, and the ink can flow from the ink bottle 1 to the inkjet imaging device 100.

[0076] The supporting part 311 extends in the axial direction L away from the ink outlet 23. The supporting part 311 is a circular arc-shaped wall. The number of supporting parts 311 can be multiple, which is not limited in the present application. In the present embodiment, the supporting part 311 is a pair of circular arc-shaped walls symmetrically arranged.

[0077] The elastic element is installed between the valve core 31 and the valve core seat 32. Specifically, the valve core 31 is provided with a first fixing part 312 extending downward in the axial direction L between the blocking part 310 and the two supporting parts 311, the connecting wall 3222 of the valve core seat 32 is provided with a second fixing part 3224 extending upward in the axial direction L, and the elastic element 33 is installed between the first fixing part 312 and the second fixing part 3224. In the present embodiment, the elastic element 33 is a spring. Other materials with elasticity can also be used.

[0078] The working principle of the ink bottle in the present embodiment is as follows:

[0079] 1. During transportation or storage, the valve core 31 closes the first opening and the second opening under the action of the elastic element 33 to prevent ink leakage.

[0080] 2. During installation, referring to Figure 4 and Figure 5 , the edge of the positioning hole 103 on the positioning plate 101 of the inkjet imaging device 100 is clamped into the clamping groove 25, so that the ink bottle 1 is stably connected with the inkjet imaging device 100. At the same time, the air guide column 102 on the inkjet imaging device 100 abuts against the valve core 31 through the gas passage 231. As the ink bottle 1 further approaches the inkjet imaging device 100, the valve core 31 slides in the valve core accommodating part 321 in the direction of the bottle main body 11 against the elastic force of the elastic element 33 until the first opening and the second opening are completely opened. When the valve core 31 is opened, the ink stored in the storage chamber 13 flows through the ink flow passage 3223 on the valve core seat 32 to the two sides of the valve core 31, and then is injected into the ink passage of the inkjet imaging device through the ink outlet nozzle 232, completing the ink supply process.

[0081] The ink bottle 1 is pre-fixed on the ink jet imaging device 100 through the clamping groove 25, so that the ink bottle is stable during installation. Thus, when the valve core 31 is opened, the ink bottle 1 can be effectively prevented from being bounced back due to the reaction force of the elastic element 33, so as to ensure the stability of the device and the accuracy of ink supply.

[0082] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the patent scope of the present application. It should be pointed out that, for those skilled in the art, without departing from the protection scope of the present application.
