Description

Technical Field

[0001] This invention relates to the field of printing equipment technology, and more particularly to an image forming apparatus. Background Technology

[0002] Inkjet printers are widely used as one of the important devices for office automation and home printing.

[0003] Inkjet printers feature a horizontally movable carriage and ink cartridges mounted on it. The bottom of each cartridge has a liquid ejector for spraying liquid onto the media. To achieve color printing, the internal space of a single ink cartridge is divided into three or four compartments by partitions to hold three or four colors of ink. Compared to a single-color cartridge, this effectively reduces the number of cartridges, decreases the internal space required for cartridge installation, and thus reduces the overall size of the inkjet printer.

[0004] Inkjet printers also have ink tanks, which supply ink to ink cartridges via supply tubes. However, there are challenges in connecting the supply tubes to the ink cartridges, making the operation complex. Summary of the Invention

[0005] In view of this, the present invention provides an image forming apparatus to solve the technical problems of difficult connection and complex operation between the supply tube and the ink cartridge in the prior art.

[0006] To achieve the above objectives, the present invention provides an image forming apparatus, comprising: a frame and a liquid delivery pipeline, a first container, and a second container disposed on the frame; the liquid delivery pipeline includes multiple supply pipes that connect the first container and the second container to deliver liquid from the first container to the second container; the frame includes a movable base, the second container is mounted on the movable base, the second container is provided with a cover member, the cover member includes a mating part and at least one mounting part, and the multiple supply pipes are connected to the second container through corresponding mounting parts; any mounting part and the mating part can be independently rotatably connected or disassembled.

[0007] In one possible implementation, the mating part has an installation area and a connecting block. The installation part has a notch that mates with the connecting block to allow the installation part to enter the installation area. When the installation part rotates relative to the installation area until the connecting block is misaligned with the notch, the installation part connects with the mating part.

[0008] In one possible implementation, the mounting area is a mounting slot.

[0009] In one possible implementation, a plurality of connecting blocks are provided circumferentially along the mounting area, and a plurality of recesses are provided circumferentially along the mounting portion.

[0010] In one possible implementation, the mounting portion is provided with a raised rib, which is located between adjacent recesses.

[0011] In one possible implementation, the mounting portion is provided with a liquid inlet port that extends along the height direction perpendicular to the frame.

[0012] In one possible implementation, at least a portion of the plurality of supply tubes are arranged along the height direction of the frame.

[0013] In one possible implementation, a plurality of the supply tubes extend toward the mating portion from the same side of the mating portion.

[0014] In one possible implementation, the movable seat has a limiting plate and a fourth limiting portion, and the supply pipe is located between the limiting plate and the fourth limiting portion.

[0015] In one possible implementation, along the extension direction of the supply pipes, a plurality of the supply pipes are sequentially separated in their arrangement order to dock with the liquid inlet.

[0016] Compared with the prior art, the present invention has the following advantages: the mounting part and the mating part are rotatably engaged to achieve connection or disassembly, which has the advantages of simple operation and easy assembly. At the same time, the mounting part and the mating part can improve the sealing of the connection between the supply pipe and the second container, ensuring the smooth supply of liquid.

[0021] To better understand the technical solution of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0024] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0025] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of the present invention are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of the present invention. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0026] This application provides an image forming apparatus (e.g., an inkjet printer). For ease of description, the following description will utilize a Cartesian coordinate system of X, Y, and Z as needed. The first direction X is defined as the width direction of the image forming apparatus, corresponding to the width direction of the frame; the second direction Y is defined as the length direction of the image forming apparatus, corresponding to the length direction of the frame; and the third direction Z is defined as the height direction of the image forming apparatus, corresponding to the height direction of the frame. The first direction X is consistent with the direction of movement of the imaging medium P (e.g., paper), and the third direction Z is perpendicular to the first direction X and the second direction Y. Furthermore, based on the user's position when using the inkjet printer, the left side of the inkjet printer corresponding to the user is defined as "left," and the right side corresponding to the user is defined as "right." Specifically, Figures 1 to 3 The left and right directions shown in the diagram are consistent with the defined left and right directions. Figure 4 and Figure 5 The left and right directions shown in the diagram are opposite to the defined left and right directions.

[0027] like Figure 1 As shown, the image forming apparatus includes a frame 1 and a media transport assembly 2. The media transport assembly 2 includes a transport path 21 that runs through the frame 1 in a first direction X, and the imaging medium P (e.g., paper) can move along the transport path 21. The media transport assembly 2 also includes a storage tray 22 disposed at the beginning of the transport path 21, a paper discharge tray 24 disposed at the end of the transport path 21, and a set of transport rollers that drive the imaging medium P to move.

[0028] Specifically, the conveyor roller assembly includes a paper feed roller 231, a paper delivery roller 232, and a discharge roller (not shown in the figure). The paper feed roller 231 picks up the imaging medium P stored in the storage tray 22 and sends the imaging medium P into the conveying path 21. The paper delivery roller 232 receives the imaging medium P and drives the imaging medium P to move along the conveying path 21. During this process, an image is formed on the imaging medium P. The imaged imaging medium P is discharged onto the paper discharge tray 24 under the action of the discharge roller.

[0029] Specifically, such as Figure 2 and Figure 3As shown, the image forming apparatus further includes: a liquid delivery pipeline 3, a first container 4, and a second container 5. The liquid delivery pipeline 3 connects the first container 4 and the second container 5 to deliver liquid from the first container 4 to the second container 5. The frame 1 includes a transverse support 11, on which the first container 4 is mounted.

[0030] The first container 4 includes a liquid storage chamber for storing liquid and an ink inlet connected to the liquid storage chamber, through which the user can replenish the liquid into the liquid storage chamber. The first container 4 includes at least four liquid storage chambers, which respectively store black (B), cyan (C), red (M), and yellow (Y) liquids.

[0031] The second container 5 can be four single-color containers to store four different colored liquids, or a multi-color container with multiple independent cavities for storing liquids of different colors.

[0032] The liquid delivery pipeline 3 includes multiple supply pipes, which are used to deliver black (B), cyan (C), red (M), and yellow (Y) liquids respectively.

[0033] For example, the first container 4 includes a first sub-container 41 for storing black liquid and a second sub-container 42 for containing colored liquid, the first sub-container 41 and the second sub-container 42 being located at opposite ends of the transverse support 11. In some other embodiments, the first sub-container 41 and the second sub-container 42 may both be located at one end of the transverse support 11.

[0034] Accordingly, the supply pipe includes a first supply pipe 31 connecting the first sub-container 41 and the second container, and a second supply pipe 32 connecting the second sub-container 42 and the second container.

[0035] For example, one end of a first supply pipe 31 for conveying black (B) liquid is connected to a first sub-container 41, and the other end is connected to a receiving cavity in a second container 5 for storing black (B) liquid, thereby enabling the supply of black liquid to the second container 5; one end of a second supply pipe 32 for conveying cyan (C) liquid is connected to a second sub-container 42 for storing cyan (C) liquid, and the other end is connected to a receiving cavity in a second container 5 for storing cyan (C) liquid, thereby enabling the supply of cyan (C) liquid to the second container 5; one end of a second supply pipe 32 for conveying red (M) liquid is connected to a second sub-container 42 for storing red (M) liquid, and the other end is connected to a receiving cavity in a second container 5 for storing red (M) liquid, thereby enabling the supply of red (M) liquid to the second container 5; one end of a second supply pipe 32 for conveying yellow (Y) liquid is connected to a second sub-container 42 for storing yellow (Y) liquid, and the other end is connected to a receiving cavity in a second container 5 for storing yellow (Y) liquid, thereby enabling the supply of yellow (Y) liquid to the second container 5. The extension paths of different supply pipes can be different.

[0036] For example, the first container 4 has a liquid outlet, and the supply pipe is a flexible hose that is directly fitted onto the outer periphery of the liquid outlet. To ensure the connection strength between the supply pipe and the liquid outlet, they are interference-fitted.

[0037] Specifically, the bottom of the second container 5 is equipped with a liquid ejector head, which can eject the liquid in the container cavity, thereby achieving imaging on the imaging medium P. For example... Figure 1 As shown, to facilitate the spraying of liquid from the liquid nozzle of the second container 5 to different positions on the imaging medium P, the frame 1 is provided with a sliding frame, which includes a guide rod 12 and a movable seat 13. The guide rod 12 extends along the second direction Y, and the movable seat 13 is slidably connected to the guide rod 12 and can slide along the guide rod 12. The second container 5 is mounted on the movable seat 13, so that the second container 5 can also move along the second direction Y under the carrying of the movable seat 13. When the imaging medium P moves along the first direction X on the transport path 21, the second container 5 moves along the second direction Y and sprays liquid (e.g., ink) onto the imaging medium P during the movement to form an image on the imaging medium P.

[0038] More specifically, such as Figure 7As shown, the movable base 13 includes a base body 131 and a cover member 132 connected to the base body 131. The base body 131 has a container housing, in which the second container 5 is fixed. The cover member 132 is provided with a liquid inlet. The cover member can be used to seal and connect the second container. A supply pipe communicates with the liquid inlet, and the liquid inlet communicates with the receiving cavity of the second container 5 through a liquid valve and a sealing cap assembly, allowing liquid in the supply pipe to flow into the receiving cavity of the second container 5. When the cover member 132 is closed on the base body 131, the liquid valve is in the open state, allowing liquid to flow from the liquid inlet into the receiving cavity through the liquid valve. When the cover member 132 is rotated open relative to the base body 131, the liquid valve is in the closed state, preventing liquid from flowing out and thus preventing liquid from contaminating the image forming apparatus. Accordingly, the receiving cavities storing different colored liquids correspond to different liquid inlets and liquid valves, so that the supply pipes for transmitting different colored liquids can be connected to the liquid inlets.

[0039] In one specific implementation, such as Figure 2 and Figure 3 As shown, at least a portion of the multiple supply pipes are arranged along the third direction Z, which reduces the size of the liquid delivery pipe 3 along the first direction X, thus helping to reduce the volume of the image forming apparatus and achieve miniaturization of the image forming apparatus.

[0040] For example, the projection areas of the portions of the multiple supply pipes that are restricted in the third direction Z overlap with each other to form a first overlap area.

[0041] Specifically, such as Figure 4 As shown, the horizontal support 11 has a first limiting part 111, and the portions of the multiple supply pipes that are limited by the first limiting part 111 are arranged along the third direction Z.

[0042] The first limiting part 111 fixes multiple supply tubes to the transverse support 11, keeping the portion of the supply tube limited by the first limiting part 111 stationary when supplying liquid, thus improving the stability of the image forming apparatus during operation. Simultaneously, the first limiting part 111 arranges the multiple supply tubes in contact with it along the third direction Z, and the projection areas of the portions of the multiple supply tubes limited by the first limiting part in the third direction Z overlap to form a first overlap area, reducing the size of the multiple supply tubes in the first direction X.

[0043] For example, along the extension direction of the supply tube, the portion of the supply tube between the first container 4 and the first limiting portion 111 is fixed to the transverse support 11 and can remain stationary relative to the transverse support 11; the supply tube is a flexible tube, and along the extension direction of the supply tube, the portion from the first limiting portion 111 to the second container 5 can move relative to the transverse support 11.

[0044] For example, the first limiting part 111 can be any structure that can fix the supply tube in the third direction Z, such as a buckle extending in the third direction Z.

[0045] More specifically, such as Figure 4 As shown, for the scheme in which the first sub-container 41 and the second sub-container 42 are located at both ends of the frame 1, the first supply pipe 31 and the second supply pipe 32 meet at the first limiting part 111. Therefore, the first limiting part 111 also serves to fix the first supply pipe and the second supply pipe together.

[0046] Furthermore, the first supply pipe 31 has a second extension section 312 and an inclined section 313 on both sides of the first limiting part 111, and the transverse bracket 11 has two fifth limiting parts 116 on the right side of the first limiting part 111. The fifth limiting parts 116 are used to fix the first supply pipe 31. The part of the first supply pipe 31 between the two fifth limiting parts 116 is the first extension section 311. The first extension section 311 and the second extension section 312 are misaligned in the third direction Z.

[0047] For example, the fifth limiting part 116 is a snap-fit ​​or other structure that can fix the supply tube in a third direction Z.

[0048] Furthermore, the transverse support 11 has a second limiting part 112, and the portions of the multiple second supply pipes 32 that are limited by the second limiting part 112 are arranged along the third direction Z.

[0049] The second limiting part 112 fixes the multiple second supply tubes 32 to the transverse support 11, so that the portion of the second supply tube 32 limited by the second limiting part 112 remains stationary when supplying liquid, thereby improving the stability of the image forming apparatus during operation. At the same time, the second limiting part 112 arranges the second supply tubes 32 in contact with it along the third direction Z, thereby reducing the size of the multiple second supply tubes 32 in the first direction X.

[0050] For example, the projection areas of the portions of the multiple second supply tubes 32 that are limited by the second limiting part in the height direction Z of the frame 1 overlap to form a second overlapping area. The supply tubes are arranged in an orderly manner in the height direction, and the minimum interval between the adjacent edges of the first and second overlapping areas is 0, effectively reducing the size of the supply tubes in the first direction X, that is, greatly reducing the size of the printer in the width direction, without affecting the flexibility of the supply tube movement. While ensuring unrestricted movement of the supply tubes and continuous ink supply, the front-to-back dimensions of the printer are significantly reduced, thereby reducing the overall size of the printer. Furthermore, in some other embodiments, by utilizing the height arrangement of the supply tubes and controlling the interval between the first and second overlapping areas, or the partial overlap of the first and second overlapping areas, the printer size can be flexibly set, allowing for the selection of the most suitable size for space design, achieving a combined balance between continuous ink supply and effective space utilization.

[0051] For example, the second limiting part 112 is a buckle or other structure that can fix the supply tube in the third direction Z.

[0052] Specifically, for the scheme where the first sub-container 41 and the second sub-container 42 are located at opposite ends of the frame 1, in order to ensure that the first supply pipe 31 and the second supply pipe 32 extend in the same direction when they meet, the portion of the second supply pipe 32 between the first limiting part 111 and the second limiting part 112 is bent. By bending, the extension direction of the second supply pipe is changed, ultimately causing the first supply pipe and the second supply pipe to extend in the same direction. Similarly, a similar limiting structure can be selected to change the extension direction of the first supply pipe so that the first supply pipe and the second supply pipe extend in the same direction, which will not be elaborated here.

[0053] For example, the portion of the second supply tube 32 between the first limiting portion 111 and the second limiting portion 112 is a first curved section 321.

[0054] More specifically, along the third direction Z, the arrangement order of the multiple second supply pipes 32 at the first limiting part 111 is the same as the arrangement order at the second limiting part 112, so that the bending degree (i.e. bending radius) of the multiple first bending segments 321 is similar, preventing some of the first bending segments 321 from being under too much stress and breaking due to the bending radius being too small.

[0055] The second supply pipe 32, which extends from the second limiting part 112 toward the first sub-container 41, bends sequentially along the third direction Z, meaning that the second supply pipe 32, which is at its highest position in the second limiting part 112, remains at its highest position when it extends to the first limiting part 111, and the second supply pipe 32, which is at its lowest position in the second limiting part 112, remains at its lowest position when it extends to the first limiting part 111.

[0056] Since multiple first curved segments 321 overlap in the first direction X, in order to provide sufficient space for the multiple first curved segments 321, when viewed along the third direction Z, the portion of the second supply pipe 32 limited by the first limiting part 111 and the portion limited by the second limiting part 112 are at least partially misaligned, that is, the first overlapping area and the second overlapping area are at least partially misaligned.

[0057] For example, such as Figure 4 As shown, the transverse support 11 has a guide post 113, which has a guide arc surface. The first bending section 321 is guided by the guide arc surface, so that the first bending section 321 is arc-shaped, preventing the first bending section 321 from being over-bent and causing excessive stress and cracking.

[0058] For example, the guide post 113 can be cylindrical or semi-cylindrical. The bending angle of the first bending segment 321 is close to 180°.

[0059] Furthermore, such as Figure 4 As shown, the second supply pipe 32 has a third extension 323 on the side of the second limiting part 112 facing the second sub-container 42, and a fourth extension 324 on the side of the first limiting part 111 facing the second sub-container 42. The third extension 323 and the fourth extension 324 are misaligned in the third direction Z.

[0060] In addition, in order to allow the first supply pipe 31 and the second supply pipe 32 to meet smoothly at the first limiting part 111, the second extension section 312 is parallel to the fourth extension section 324, and the second extension section 312 can be arranged adjacent to the fourth extension section 324 in the third direction Z and then extend in the same direction.

[0061] In one specific implementation, such as Figure 4 and Figure 5 As shown, the second supply pipe 32 has a second bend 322 communicating with the third extension 323. The second bend 322 is connected to the liquid outlet of the second sub-container 42 so that liquid in the second sub-container 42 can flow into the second supply pipe 32. The second bend 322 is arranged along the second direction Y.

[0062] As the distance between the second sub-container 42 and the corresponding second limiting part 112 increases, the radius of the second bending section 322 connected to the second sub-container 42 gradually increases, thereby enabling multiple second supply pipes 32 to be connected to the corresponding second sub-container 42 in sequence through the second bending section 322, and the arrangement of the second bending section 322 is relatively regular.

[0063] As the distance between the second sub-container 42 and the corresponding third extension 323 increases, the length of the third extension 323 gradually increases, causing the multiple second supply pipes 32 to meet sequentially in the order of the portion restricted by the second limiting part 112.

[0064] For example, multiple second sub-containers 42 are arranged along the second direction Y. The second bending segment 322 of the second supply pipe 32, which is at the highest point along the third direction Z, has the largest radius and the third extension segment 323 has the longest length. The second bending segment 322 of the second supply pipe 32, which is at the lowest point along the third direction Z, has the smallest radius and the third extension segment 323 has the shortest length.

[0065] For example, the bending angle of the second bending segment 322 is close to 90°.

[0066] Furthermore, such as Figure 4 and Figure 5 As shown, a plurality of third limiting parts 114 are provided on the transverse support 11. The third limiting parts 114 are disposed between the second limiting parts 112 and the second bending section 322 to fix the second supply pipe 32 at the meeting position of the second supply pipe 32, so that the third extension section 323 and the second bending section 322 remain stationary when supplying liquid, thereby improving the stability of the image forming apparatus during operation.

[0067] For example, the third limiting part 114 can be any other structure that can fix the supply tube in the third direction Z, such as a buckle extending along the third direction Z.

[0068] Furthermore, such as Figure 5 As shown, the transverse support 11 is provided with a plurality of guide grooves 115. At least one side wall of the guide groove 115 has a guide arc surface. The second bending segment 322 is guided by the guide arc surface, thereby making the second bending segment 322 arc-shaped. This prevents the second bending segment 322 from being over-bent and causing excessive stress and cracking, or prevents the second bending segment 322 from being too bent and interfering with other second bending segments 322.

[0069] In one specific implementation, such as Figure 2 and Figure 3 As shown, the supply tube extends from the same side of the movable seat 13 to connect with the liquid inlet. Multiple supply tubes can be separated when they extend above the movable seat 13. That is, the extension direction of multiple supply tubes between the first limiting part 111 and the movable seat 13 is the same, thereby making the internal structure of the image forming apparatus more neat.

[0070] Specifically, the movable seat 13 has a limiting plate 133 that abuts against the supply pipe, causing the supply pipe to bend to connect with the liquid inlet. The limiting plate 133 does not cause the supply pipe to bend excessively, thus not affecting the smooth supply of liquid.

[0071] The movable base 13 is also provided with a fourth limiting part 134, and multiple supply tubes are restricted between the fourth limiting part 134 and the limiting plate 133. Along the extension direction of the supply tubes, after leaving the fourth limiting part 134, the multiple supply tubes separate sequentially according to their arrangement order to connect with different liquid inlets, making the internal structure of the image forming apparatus relatively neat.

[0072] For example, the surface of the fourth limiting part 134 that contacts the supply tube is arc-shaped, thereby guiding the supply tube to bend, and the surface of the fourth limiting part 134 that contacts the supply tube has no sharp point, so as not to puncture the supply tube or cause the supply tube to bend excessively.

[0073] More specifically, the second container 5 moves along the second direction Y under the carrying of the movable seat 13, and therefore the end of the supply pipe connected to the movable seat 13 also moves accordingly. The farthest position that the movable seat 13 can move to in the second direction Y is the first limit position and the second limit position. Figure 2 This shows the movable seat 13 moving to its first extreme position. Figure 3 The movable seat 13 is shown moving to the second extreme position.

[0074] like Figure 2 and Figure 3 As shown, the extension direction of the supply tube at the first limiting part 111 is opposite to the extension direction of the supply tube at the limiting plate 133 in the Y direction. That is, when viewed downwards along the third direction Z, the supply tube extends from the left side of the movable seat 13 to the top of the movable seat 13, and after passing the first limiting part 111, the supply tube extends to the left side of the frame 1. Figure 2 As shown, when the movable seat 13 moves to the first limit position, and as... Figure 3 As shown, when the movable seat 13 moves to the second limit position, the supply pipe can move within a small space following the displacement of the movable seat.

[0075] Furthermore, the first limiting part 111 is located at the center of the frame 1 in the second direction Y, such that the distance between the first limiting part 111 and the first limit position and the second limit position is equal or close, thereby allowing the length of the supply tube to be set relatively short.

[0076] Understandably, the first limiting part 111 can be located near the center region of the frame 1 in the second direction Y, and does not need to be set at the exact center in a mathematical sense. Preferably, the first limiting part 111 can also be set at a position slightly to the left of the center of the frame 1 in the second direction Y.

[0077] For example, when viewed downward along the third direction Z, when the movable seat 13 moves to the first limit position, the distance between the first limiting part 111 and the left side of the movable seat 13 is 144.82 mm, and when the movable seat 13 moves to the second limit position, the distance between the first limiting part 111 and the left side of the movable seat 13 is 150.48 mm.

[0078] In one specific implementation, such as Figure 6 and Figure 7 As shown, the movable seat 13 can be provided with the cover member 132 of the second container as its sealing connection member. The cover member can also be part of the structure of the second container to realize the sealing and connection functions. The cover member is provided with a mating part 7 and at least one mounting part 6. Multiple supply pipes are connected to the second container 5 through the corresponding mounting part 6. Any mounting part 6 and mating part 7 can be independently rotated and connected or disassembled.

[0079] For example, the mating part 7 can be a sealing cap bracket, and the mounting part 6 can be a sealing cap cover.

[0080] The mounting part 6 and the mating part 7 are rotatably connected to achieve the connection or disassembly of the two, which has the advantages of simple operation and easy assembly. At the same time, the mounting part 6 and the mating part 7 can improve the sealing of the supply pipe and the second container 5, ensuring the smooth supply of liquid.

[0081] Specifically, such as Figure 8 and Figure 9 As shown, the mating part 7 has an installation area 71 and a connecting block 72, and the mounting part 6 has a recess 61. The recess 61 mates with the connecting block 72 so that the mounting part 6 enters the installation area 71. When the mounting part 6 rotates relative to the installation area 71 until the connecting block 72 and the recess 61 are misaligned, the mounting part 6 connects with the mating part 7.

[0082] Correspondingly, when it is necessary to disassemble the mounting part 6 and the mating part 7, that is, to disconnect the mounting part 6 and the mating part 7, the mounting part 6 can be rotated relative to the mounting area 71 until the connecting block 72 corresponds to the recess 61, and then the mounting part 6 can be removed from the mounting area 71. Therefore, the assembly and disassembly of the movable seat 13 has the advantages of being simple and quick to operate.

[0083] For example, the mounting area 71 is a mounting groove, which can limit the range of motion of the mounting part 6 and guide the mounting part 6 to rotate relative to the mounting area 71 when the mounting part 6 is subjected to external force.

[0084] For example, a plurality of connecting blocks 72 are provided along the circumference of the mounting area 71, and a plurality of recesses 61 are provided along the circumference of the mounting part 6, so that the fitting between the mounting part 6 and the mating part 7 is more reliable, and the mounting part 6 is not easy to separate from the mating part 7 when the mounting part 6 and the mating part 7 are in the connected state.

[0085] For example, three connecting blocks 72 are evenly arranged along the circumference of the mounting area 71, and three recesses 61 are evenly arranged along the circumference of the mounting part 6, and the three connecting blocks 72 can respectively cooperate with the three recesses 61.

[0086] More specifically, the mounting section 6 is provided with a liquid inlet 62, which extends in the direction perpendicular to the third party Z, so that the part of the supply pipe connected to the liquid inlet 62 can extend in the direction perpendicular to the third party Z, and most of the supply pipe can extend in the direction perpendicular to the third party Z.

[0087] For example, to ensure the connection strength between the supply pipe and the mounting part 6, they are interference-fitted.

[0088] Furthermore, such as Figure 9 As shown, the mounting part 6 is provided with a protruding rib 63, which is located between adjacent recesses 61. When the user assembles or disassembles the end of the supply pipe connected to the movable seat 13, the user can contact the protruding rib 63 with his hand or a tool, so as to apply force to the mounting part 6 and make the mounting part 6 rotate.

[0089] Furthermore, multiple supply pipes extend from the same side of the mating part 7 toward the mating part 7, thereby making the structure of the supply pipes neater and facilitating the fixing of the supply pipes.

[0090] Specifically, the supply tube extends from the same side of the movable seat 13 to above the movable seat 13, and this side is called the entry side. The limiting plate 133 protrudes from the entry side along the second direction Y, so that it can contact the supply tube earlier and guide the supply tube to extend upwards towards the movable seat 13.

[0091] For example, the end of the limiting plate 133 protruding from the entry side is provided with a buckle, which can fix the supply pipe and improve the stability of the supply pipe during operation.

[0092] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
