Description

Technical Field

[0001] This disclosure relates to the technical field of concealed tank assemblies for toilets, and more particularly to panel assemblies for concealed tanks and concealed tank assemblies for toilets. Background Technology

[0002] In the sanitation sector, some toilet tanks are installed within the wall. Tanks installed within the wall are referred to as concealed tanks. For concealed tanks installed within the wall, a panel assembly needs to be connected to the front side of the concealed tank. The panel assembly includes a retaining bracket and a panel, which, in its assembled state, is connected to the retaining bracket by a connecting device (e.g., a clamping structure) to facilitate a snap-fit ​​connection between the retaining bracket and the panel. At least one pneumatic element is provided on the retaining bracket to control a pneumatic drain valve placed within the concealed tank. The retaining bracket is connected to the concealed tank via at least one connector (including a pin, screw, or the like). At least one button is provided on the panel to trigger at least one pneumatic element of the retaining bracket. In the assembled state of the panel assembly, the panel covers the end of at least one connector.

[0003] For preventative maintenance of the concealed water tank, the panel attached to the retainer needs to be removed from the retainer. To remove the panel from the retainer, a specific tool must be used to pry up one edge of the panel, and then at least one connector must be removed.

[0004] The disadvantages of the solutions provided in the prior art are as follows: 1. Because the panel needs to be removed from the retaining bracket, and it is difficult to remove the panel manually, special tools are required for removal. Therefore, it is inconvenient for users to obtain the specific tools needed to pry the panel off the retaining bracket to perform preventative maintenance on the concealed water tank.

[0005] 2. Due to repeated disassembly and reassembly of the panel and retaining bracket, the clamping structure and panel assembly in the existing technology deform, resulting in unstable and loose connections between the panel and retaining bracket. Therefore, the panel assembly needs to be replaced, which increases the maintenance cost of the concealed water tank. Summary of the Invention

[0006] This disclosure aims to overcome the aforementioned deficiencies by providing a panel assembly for a concealed toilet tank and a concealed tank assembly for a toilet. The panel assembly includes a retainer bracket connectable to the concealed tank, the retainer bracket having a tablet slot through which a cleaning tablet is inserted into the concealed tank. The panel assembly includes a panel that is connected to the retainer bracket in an assembled state. The assembled state of the panel assembly includes a closed state and an open state, in which the panel conceals the tablet slot of the retainer bracket, and in the open state, the tablet slot of the retainer bracket is accessible for inserting a cleaning tablet into the concealed tank. The panel is slidably connected to the retainer bracket by a sliding structure, allowing the panel to slide relative to the retainer structure without removing the panel from the retainer bracket, facilitating later maintenance. The subject matter of this disclosure improves maintenance efficiency, reduces maintenance-related costs by eliminating the need to replace old panel assemblies with new ones, and also ensures stable assembly of the panel and retainer bracket.

[0007] This disclosure provides a panel assembly for a concealed tank of a toilet. The panel assembly includes a retaining bracket with pneumatic elements and a panel with a button. The retaining bracket includes a mounting frame that can be connected to the tank window or cover of the concealed tank using multiple connectors, and includes a bracket body that snaps into the mounting frame. The panel includes at least one button configured to move rearward relative to the panel to actuate at least one flush valve of the concealed tank to perform a toilet flush.

[0008] The panel is connected to the front of the retainer via a sliding structure, allowing the panel to be slidably connected to the retainer in the assembled state, thus enabling the panel to slide relative to the retainer. In the closed state of the panel assembly, the panel covers the front of the retainer and conceals the tablet slot. In the closed state of the panel assembly, the button position corresponds to the position of the pneumatic component.

[0009] To switch between a closed and open state of the panel assembly, the panel of the panel assembly is configured to slide laterally or vertically relative to a retaining bracket. In one example, the panel assembly includes at least one pivot component connected to at least one button to pivot the at least one button relative to the panel, thereby switching between a closed and open state of the panel assembly.

[0010] In the example, the sliding structure includes a guide groove and a guide rail, which is configured to slidably engage with the guide groove (e.g., configured to slide in the guide groove).

[0011] The guide rail groove is provided on the retaining bracket, and the guide rail is provided on the panel. Alternatively, the guide rail is provided on the retaining bracket, and the guide rail groove is provided on the panel.

[0012] In the example, the sliding structure includes a guide groove and a guide post, the guide post being configured to slidably engage with the guide groove (e.g., being configured to slide within the guide groove).

[0013] The guide groove is disposed on the retaining bracket, and the guide post is disposed on the panel. Alternatively, the guide post is disposed on the retaining bracket, and the guide groove is disposed on the panel.

[0014] In the example, the sliding structure includes a guide groove and a plurality of guide posts. The plurality of guide posts are arranged at intervals along the extension direction of the guide groove, and the plurality of guide posts are configured to slidably engage with the guide groove, respectively.

[0015] In the example, the sliding structure includes two guide slots and multiple guide posts. The two guide slots are arranged in parallel, some of the multiple guide posts are configured to slidably engage with one of the guide slots, and the other guide posts are configured to slidably engage with the other guide slot.

[0016] In the example, the guide groove is set on the retainer and passes through the front and rear surfaces of the retainer.

[0017] Guide posts are located on the rear side of the panel. Two guide post flanges are located at the ends of the guide posts and spaced apart (e.g., spaced apart from each other), forming a limiting groove between the two guide post flanges.

[0018] The wall of each of the guide slots is configured to slidably engage in (e.g., configured to slide in a limiting slot) a limiting slot.

[0019] In the example, groove wall notches are provided on the groove wall of each of the guide grooves and are configured to allow the corresponding guide post flanges to pass through.

[0020] In the example, the elastic member is configured to drive the panel to reset and is connected between the panel and the retaining bracket.

[0021] In the example, the retaining bracket includes a mounting frame configured to connect to a concealed water tank, and a bracket body configured to clamp with the mounting frame.

[0022] Pneumatic components are mounted on the main body of the support frame.

[0023] In the example, the tablet slot is positioned on the retainer and configured to inject detergent.

[0024] When the panel is closed, it covers the tablet slot.

[0025] When the panel is in the open position, the panel is away from the tablet slot.

[0026] In the example, the tablet slot is positioned on one side of the retainer.

[0027] In the example, the back side (i.e., the rear side) of the tablet slot is connected to the injection tube.

[0028] This disclosure also provides at least one concealed tank assembly for a toilet, having a concealed tank according to any of the foregoing examples of this subject matter and at least one panel assembly.

[0029] In the example, the concealed water tank includes a tank window located on the front side of the concealed water tank, and a retaining bracket is attached to the tank window.

[0030] By adopting the above technical solution, the present invention brings the following beneficial effects: A panel assembly for a concealed toilet tank according to the subject matter of this disclosure includes a retainer and a panel. The retainer includes a pneumatic element. One end of the retainer is connected to and secured to the concealed tank via a connector, and the pneumatic element is configured to control a pneumatic flush valve within the concealed tank. The panel includes a button, and the panel is connected to the retainer via a sliding structure. When the panel is in an initial or closed state, the panel covers the front side of the retainer, and the position of the button corresponds to the position of the pneumatic element in a front-to-back direction. When the panel is pushed, the panel can slide laterally or vertically relative to the retainer. The user can select which end of the retainer needs to be exposed so that the connector is exposed at the end as needed. Further, the subject matter of this disclosure provides a concealed tank assembly having a concealed tank and a panel assembly connected to the concealed tank. In an example, the concealed tank includes a tank window or cover connected to the concealed tank, a panel assembly connected to the tank window or cover, a detergent dispenser connected to the panel assembly for stacking cleaning tablets, and at least one flush valve connected to the panel assembly via at least one flexible hose.

[0035] A panel 12 is disposed on the front side of a retainer 11 and is connected to the retainer body 112 of the retainer 11 via a sliding structure 15. When the panel 12 is in the closed state, the panel 12 completely or substantially covers the front side of the retainer body 112 of the retainer 11. The panel 12 includes a button 14 configured to move rearward relative to the panel 12 to trigger at least one flush valve of the concealed tank 16 to perform a toilet flush. In the example, the button 14 includes at least one button 141, 142, wherein at least one button 141, 142 and at least one pneumatic element 13 are correspondingly configured such that at least one button 141, 142 is positioned corresponding to the position of at least one pneumatic element 13. At least one button 141, 142 of the button 14 is connected to the panel assembly 12 to trigger the flushing action of the concealed tank 16. In the example, buttons 141, 142 of the button 14 are connected to the panel assembly 12 to perform a large flush and a small flush, respectively.

[0036] Panel 12 is configured to slide laterally or vertically relative to the support body 112 of retaining bracket 11 in order to switch from a closed state to an open state.

[0037] The panel assembly according to the subject matter of this disclosure is used in a concealed water tank 16. The panel assembly 100 includes a retaining bracket 11 connectable to the concealed water tank 16, the retaining bracket 11 having a tablet slot 114 through which cleaning tablets are inserted into the concealed water tank 16. The panel assembly 100 includes a panel 12 connected to the retaining bracket 11 in an assembled state. The assembled state of the panel assembly 100 includes a closed state and an open state. In the closed state, the panel 12 conceals the tablet slot 114 of the retaining bracket 11. In the open state, the tablet slot 114 of the retaining bracket 11 is accessible for inserting cleaning tablets into the concealed water tank 16. The retaining bracket 11 includes a mounting frame 111 connectable to a tank window 161 or cover 18 of the concealed water tank 16 using multiple connectors, and includes a bracket body 112 that snaps into the mounting frame 111. The bracket body 112 includes a plurality of clearance slots 118 corresponding to a plurality of connectors, such that the mounting frame 111 can be connected to the tank window 161 or the cover 18, and the bracket body 112 includes a tablet slot 114.

[0038] In this example, pneumatic element 13 is mounted on the support body 112 of the retaining bracket 11, and is configured to control a pneumatic drain valve in the concealed water tank 16. A description of the structure and connection between pneumatic element 13 and the pneumatic drain valve is omitted here. At least one of the buttons 14, 141, 142, is mounted on the panel 12 and configured to trigger pneumatic element 13 to actuate the flushing action of the concealed water tank 16. A description of the structure and connection between buttons 14 and pneumatic element 13 is omitted here. The number of pneumatic elements 13 and buttons 14 can be set as needed. In this example, the buttons can be moved only when the panel 12 is in the closed state to trigger pneumatic element 13.

[0039] like Figures 13 to 16 As shown, the concealed water tank 16 is hidden in the wall 17. The retaining bracket 11 is fixedly or removably mounted to the wall 17 using connectors (e.g., screws). An opening is provided in the wall 17 such that a tank window 161 on the top of the front side of the concealed water tank 16 extends forward. In the example, a cover 18 (e.g., ...) replaces the tank window 161. Figure 33 and Figure 34The water tank window 161 (as shown) is connected to the concealed water tank 16. The thickness of the water tank window 161 can be adjusted according to the thickness of the wall 17 or the user's needs. For example, the thickness of the water tank window 161 can be adjusted between a maximum thickness and a minimum thickness. A retaining bracket 11 is connected to the front side of the water tank window 161 or the cover 18. The left and right ends and / or the upper and lower ends of the retaining bracket 11 are connected to the water tank window 161 or the cover 18 via connectors. The left and right ends and / or the upper and lower ends of the retaining bracket 11 are provided with connecting holes 113 for the connector to pass through and connect. The connector may include screws. By using screws on the cover 18 (such as...) Figure 33 and Figure 34 The retainer 11 is inserted into the connection hole 113, and can be fixedly or removably connected to the cover 18. In this example, for servicing the concealed water tank 16 (e.g., performing inspection and maintenance of the concealed water tank 16), it is not necessary to remove the screw from the connection hole 113 to disconnect the retainer 11. Instead, the water tank servicing can be performed using a snap-fit ​​connection, as further described below.

[0040] like Figure 33 and Figure 34 As shown, the cover 18 can be a frame with thickness. The thickness of the cover 18 can be adjusted according to the thickness of the wall 17 or the user's needs. For example, the thickness of the cover 18 can be adjusted between a maximum thickness (e.g., the cover 18 can be a cover 18a with the maximum thickness) and a minimum thickness (e.g., the cover 18 can be a cover 18b with the minimum thickness). The retaining bracket 11 can also be fixedly or detachably connected to the concealed water tank 16. In the example, the water tank window 161 or cover 18 is connected between the mounting frame 111 and the concealed water tank 16. The water tank window 161 or cover 18 is connected to the concealed water tank 16 using connectors (e.g., screws) or snap-fit ​​connections.

[0041] In the example, flexible hoses connect each of the pneumatic components 13 to each of the flush valves in the reservoir of the concealed water tank 16. In the example, the reservoir of the concealed water tank 16 includes at least one flexible hose to connect at least one pneumatic valve to at least one flush valve of the concealed water tank 16. For servicing the concealed water tank 16 (e.g., performing inspection and maintenance of the concealed water tank 16), the panel 12 and the bracket body 112 can be removed from the mounting frame 111 by removing the snap-fit ​​connection between the bracket body 112 and the mounting frame 111, and the flexible hoses can be detached from the pneumatic components 13. The water tank can then be serviced.

[0042] Similar slots can be provided on the tablet container basket, as shown in the example. Figure 35The tablet container basket 1151 shown can also be adjusted according to the wall thickness. The slot can be defined at different distances, and the tablet container basket 1151 can slide toward the injection tube 115 along different distances.

[0043] As disclosed herein, panel assembly 100 includes a sliding structure 15 for slidably connecting panel 12 to retaining bracket 11 in an assembled state, allowing sliding movement of panel 12 relative to retaining bracket 11 to switch between a closed and open state of panel assembly 100. Panel 12 is attached to the front side of bracket body 112. The sliding structure 15 allows panel 12 to slide laterally or vertically relative to the bracket body 112 of retaining bracket 11, depending on the configuration of the sliding structure 15. After installation, panel 12 is positioned on the outside of a wall for user operation.

[0044] In the example, the sliding structure 15 includes a guide rail, a slider, a guide post, a guide rail groove, a sliding groove, a guide groove, or a combination thereof, to achieve linear sliding of the panel 12.

[0045] When panel 12 is in the initial or closed state, panel 12 covers the front side of the support body 112 of retaining bracket 11, and the area of ​​panel 12 is slightly larger than the area of ​​the support body 112 of retaining bracket 11, so as to completely cover the support body 112 of retaining bracket 11. When panel 12 is in the initial or closed state, the position of at least one button 141, 142 of buttons 14 corresponds to the position of at least one pneumatic element 13 in the front-to-back direction. After the user presses at least one button 141, 142 of buttons 14, at least one button 141, 142 of buttons 14 can trigger or press its corresponding pneumatic element 13, thereby controlling the pneumatic drain valve in the concealed water tank 16.

[0046] As needed, limiting structures (such as limiting grooves, elastic members, and the like) can be provided to restrict panel 12 to an initial or closed state. In the assembled state of panel assembly 100, the user applies an external force to panel 12 to cause panel 12 to slide relative to support body 11.

[0047] In the subject of this disclosure, the state of the panel 12 after it has slid relative to the support body 112 of the retaining bracket 11 toward either side (e.g., left and right or top and bottom) is referred to as the open state, at which point the user can access the tablet slot 114 to insert a cleaning tablet into the concealed water tank 16.

[0048] When the user slides the panel 12 relative to the bracket body 112 of the retaining bracket 11, the user can select which end of the bracket body 112 of the retaining bracket 11 needs to be exposed as needed, thereby exposing the connection hole 113 at that end, and thus removing the bracket body 112 from the concealed water tank 16.

[0049] In the example, the sliding structure 15 includes a guide groove and a guide rail configured to slidably engage with the guide groove (e.g., configured to slide within the guide groove). Therefore, the sliding structure 15 allows the panel 12 to move relative to the support body 112 of the retaining bracket 11.

[0050] The guide rail groove is provided on the support body 112 of the retaining bracket 11, and the guide rail is provided on the panel 12. Alternatively, the guide rail is provided on the support body 112 of the retaining bracket 11, and the guide rail groove is provided on the panel 12.

[0051] In this example, the sliding structure 15 adopts a structure combining at least one guide rail and at least one guide rail groove, and has the following two combined installation methods.

[0052] In the first embodiment, at least one guide rail groove is provided on the front side of the support body 112 of the retaining bracket 11, and at least one guide rail is provided on the back side (i.e., the rear side) of the panel 12.

[0053] In the second embodiment, at least one guide rail is provided on the front side of the support body 112 of the retaining bracket 11, and at least one guide rail groove is provided on the back side (i.e., the rear side) of the panel 12.

[0054] Depending on the desired sliding direction, at least one guide rail and at least one guide rail groove can be selected to extend laterally or vertically. At least one guide rail fits into at least one guide rail groove, and at least one guide rail and at least one guide rail groove are assembled by a sliding connection.

[0055] In the example, such as Figures 4 to 12 As shown, the sliding structure 15 includes at least one guide groove 151 and a plurality of guide posts 152 that are slidably engaged with the at least one guide groove 151.

[0056] At least one guide groove 151 is provided on the support body 112 of the retaining bracket 11, and a plurality of guide posts 152 are provided on the panel 12. Alternatively, a plurality of guide posts 152 are provided on the support body 112 of the retaining bracket 11, and at least one guide groove 151 is provided on the panel 12.

[0057] In the example, the sliding structure 15 adopts a structure that combines at least one guide groove 151 and multiple guide posts 152, and has the following two combined installation methods.

[0058] In the first embodiment, at least one guide groove 151 is provided on the front side of the support body 112 of the retaining bracket 11, and a plurality of guide posts 152 are provided on the back side (i.e., rear side) of the panel 12. In the example, the plurality of guide posts 152 are integrated with the panel 12.

[0059] In the second embodiment, a plurality of guide posts 152 are disposed on the front side of the support body 112 of the retaining bracket 11, and at least one guide groove 151 is disposed on the back side (i.e., rear side) of the panel 12. In one example, the plurality of guide posts 152 are integrated with the support body 112 of the retaining bracket 11.

[0060] Depending on the desired sliding direction, at least one guide groove 151 can be selected to extend laterally or vertically. The end of each of the guide posts 152 is inserted into the corresponding guide groove 151, and the plurality of guide posts 152 and the corresponding guide grooves 151 are assembled via a sliding connection.

[0061] After the panel 12 is assembled onto the support body 112 of the retaining bracket 11, a plurality of guide posts 152 slidably engage with corresponding guide grooves 151. In the normal state, each of the plurality of guide posts 152 has friction with at least one guide groove 151, allowing the panel 12 to be positioned at a designated location. When the user applies an external force to slide the panel 12, the plurality of guide posts 152 slide along at least one guide groove 151, thereby causing the panel 12 to slide relative to the support body 112 of the retaining bracket 11, thus achieving the open state of the panel assembly 100.

[0062] In one example, a plurality of guide posts 152 are arranged at intervals (e.g., spaced apart from each other) along the extension direction of at least one guide groove 151, and the plurality of guide posts 152 are slidably engaged with at least one guide groove 151 respectively.

[0063] In this example, a plurality of guide posts 152 are spaced apart to form a row, and each guide post 152 is slidably engaged with at least one guide groove 151. The plurality of guide posts 152 respectively provide support for the panel 12. This improves the stability of the panel 12 assembled on the support body 112 of the retaining bracket 11, and also improves the stability of the panel 12 when sliding relative to the support body 112 of the retaining bracket 11.

[0064] In one example, such as Figure 6 , Figure 7 and Figure 11As shown, the sliding structure 15 includes two guide grooves 151 and a plurality of guide posts 152. The two guide grooves 151 are arranged in parallel, some of the guide posts 152 are slidably engaged with one of the guide grooves 151, and another of the guide posts 152 is slidably engaged with another of the guide grooves 151.

[0065] In this example, two guide slots 151 are arranged parallel to each other at intervals (e.g., spaced apart from each other). A plurality of guide posts 152 are correspondingly arranged in two rows, which engage with the two guide slots 151. This arrangement of two guide slots 151 engaging with two rows of guide posts 152 improves the stability of the panel 12 assembled on the support body 112 of the retaining bracket 11, and also improves the stability of the panel 12 when it slides relative to the support body 112 of the retaining bracket 11.

[0066] In the example, such as Figure 32 As shown, the sliding structure 15 includes three guide grooves 151 and multiple guide posts 152. The three guide grooves 151 include one guide groove 151 disposed on the upper side of the support body 112 and two guide grooves 151 disposed on the lower side of the support body 112.

[0067] In the example, such as Figure 35 and Figure 36 As shown, the sliding structure 15 includes a blocking block 153. The blocking block 153 is disposed on the rear side of the panel 12 and slidably engages with the guide groove 151. When the panel assembly 100 is assembled, the blocking block 153 is inserted into the guide groove 151. Therefore, as the panel 12 moves relative to the retaining bracket 11, the blocking block 153 can move within the guide groove 151. When the panel 12 is in its initial or closed state, the blocking block 153 is disposed at the first end of the guide groove 151.

[0068] In the example, the sliding structure 15 includes a locking device 154 disposed at the second end of the guide groove 151. When the panel 12 is opened, the blocking block 153 moves from the first end of the guide groove 151 toward the second end of the guide groove 151 until the blocking block 153 is locked by the locking device 154. The blocking block 153 can be inserted into the locking device 154 to be locked by the locking device 154.

[0069] In the example, such as Figures 5 to 12 As shown, at least one guide groove 151 is provided on the support body 112 of the retaining bracket 11 and passes through the front and rear surfaces of the support body 112 of the retaining bracket 11.

[0070] Each of the plurality of guide posts 152 includes a first guide post flange 1521A on the circumferential surface at the free end of the respective guide post 152, and each of the plurality of guide posts 152 includes a second guide post flange 1521B on the circumferential surface of the guide post 152 at a certain distance from the free end, to form a limiting groove 1522 between the first guide post flange 1521A and the second guide post flange 1521B.

[0071] At least one guide groove 151 includes a plurality of groove wall recesses 1512 on the groove wall 1511 of the at least one guide groove 151. A plurality of guide posts 152 are inserted into or removed from the at least one guide groove 151 through the plurality of groove wall recesses 1512. The groove wall 1511 of the guide groove 151 is slidably fitted in a limiting groove 1522.

[0072] In the example, at least one guide groove 151 provided on the support body 112 of the retaining bracket 11 is an elongated through hole that passes through the front and rear surfaces of the support body 112 of the retaining bracket 11.

[0073] Multiple guide posts 152 are disposed on the back side (i.e., rear side) of the panel 12, and the positions of the guide posts 152 correspond to the positions of the corresponding guide grooves 151. Each of the first guide post flange 1521A and the second guide post flange 152B is spaced apart at the end of each of the guide posts 152. In the example, each of the guide post flanges 1521A and 1521B is substantially circular and is spaced apart along the axial direction of each of the guide posts 152 to form a limiting groove 1522 between the two guide post flanges 1521. In the example, each of the guide posts 152 and each of the guide post flanges 1521A and 1521B is a plastic component. The diameter of each of the guide post flanges 1521A and 1521B is slightly larger than the width of its corresponding guide groove 151. When each of the guide posts 152 is assembled with at least one guide groove 151, the first guide post flange 1521A extends through the corresponding guide groove 151, such that the groove wall 1511 of each of the guide grooves 151 is slidably fitted in the corresponding limiting groove 1522 of each of the guide posts 152, which serves to limit the movement in the axial direction or in the front-to-back direction.

[0074] In the example, such as Figure 6As shown, each of the guide grooves 151 has a groove wall 1511 including a plurality of groove wall recesses 1512, which are configured to allow the first post flange 1521A to pass through, such that the first guide post flange 1521A passes through the corresponding guide groove 151.

[0075] The number and spacing of each of the groove wall recesses 1512 correspond to the number and spacing of the plurality of guide posts 152.

[0076] In the example, each of the guide pillars 152 has a hollow structure. This helps to reduce the weight of the structure.

[0077] In the example, the elastic member is configured to drive the panel 12 to reset and is connected between the panel 12 and the support body 112 of the retaining bracket 11. The elastic member may be a tension spring, an elastic sheet, or the like.

[0078] A tension spring or elastic sheet is connected between the panel 12 and the support body 112 of the retaining bracket 11, and is configured to pull the panel 12 to slide toward the center (initial position) of the support body 112 of the retaining bracket 11 for resetting. After releasing the panel 12, the user does not need to slide to close the panel 12. The panel 12 can close automatically, thereby improving usability.

[0079] In the example, the aforementioned elastic member can also be connected between the fixed member and the sliding member of the sliding structure 15.

[0080] In the example, such as Figures 2 to 5 As shown, the retaining bracket 11 includes a mounting frame 111 configured to connect to the concealed water tank 16 and a bracket body 112 clamped to the mounting frame 111. For example, the bracket body 112 can be mounted in the mounting frame 111 of the retaining bracket 11 by snap-fit ​​engagement at four points. Pneumatic components 13 are arranged on the bracket body 112.

[0081] In this example, the retaining bracket 11 comprises two parts: a mounting frame 111 and a bracket body 112. The mounting frame 111 is configured to connect and secure to the tank window 161 of the concealed water tank 16. Connection holes 113 are provided at both ends of the mounting frame 111. Multiple pneumatic components 13 are provided on the bracket body 112. The bracket body 112 and the mounting frame 111 are connected by a snap-fit ​​connection. This facilitates assembly and disassembly.

[0082] In the example, a snap 116 is provided at each of the two apex corners and / or the two bottom corners of the mounting frame 111, and a slot 117 is correspondingly provided at each of the two apex corners and / or the two bottom corners of the bracket body 112. When the bracket body 112 and the mounting frame 111 are assembled, the bracket body 112 can be secured in the mounting frame 111 by engaging the snaps 116 into their corresponding slots 117.

[0083] In examples within this topic, such as Figure 5 and Figure 6 As shown, the clearance groove 118 is provided on the edge of the bracket body 112 and is configured to make room for the protrusion where the connection hole 113 is located.

[0084] In the example, the support body 112 of the retainer 11 includes a tablet slot 114 configured to allow a user to inject (e.g., insert) cleaning tablets, etc., into the concealed tank 16, wherein the cleaning tablets may be made of detergent material or cleaning balls containing detergent material. In the example, detergent solution can be poured directly into the tablet slot 114. In the example, the concealed tank 16 includes a detergent cartridge 162, which allows injected detergent to fall into the detergent cartridge 162. If necessary, a conduit may be provided between the concealed tank 16 or the detergent cartridge 162 and the tablet slot 114 to guide the injected detergent into the detergent cartridge 162 of the concealed tank 16. When multiple cleaning tablets or cleaning balls are added to the concealed tank 16 via the panel assembly 100, the cleaning tablets or cleaning balls can be stacked in the detergent cartridge 162. Thus, the bottom first cleaning tablet or first cleaning ball can be exposed to the waterline in the concealed tank 16. When the cleaning tablets or cleaning balls at the bottom dissolve in water, the second cleaning tablets or cleaning balls placed on top of the first cleaning tablets or cleaning balls slide down into the water and dissolve in the water in the concealed water tank 16. Therefore, it allows users to conveniently add multiple cleaning tablets or cleaning balls to the concealed water tank 16 at once via the panel assembly 100, as the cleaning tablets or cleaning balls can dissolve gradually.

[0085] Because panel 12 is slidably connected to the support body 112 of retainer 11, panel 12 slides relative to retainer 11 to open panel assembly 100, exposing tablet slot 114 to the user for inserting cleaning tablets into concealed water tank 16. After detergent has been injected, when panel 12 conceals tablet slot 114, the user slides panel 12 in the opposite direction to close panel assembly 100.

[0086] In this example, when a user needs to inject detergent into the concealed tank 16 or the detergent dispenser 162 of the concealed tank 16, the user only needs to slide the panel 12 relative to the support body 112 of the retaining bracket 11 to open the panel assembly 100, thereby exposing the tablet slot 114, allowing the user to inject cleaning tablets into the concealed tank 16 or the detergent dispenser 162 of the concealed tank 16. There is no need to detach the panel assembly 100 from the wall 17. Therefore, it is convenient for the user and improves the user experience.

[0087] In the example, such as Figures 3 to 6 As shown, the tablet slot 114 is disposed on one side of the retainer 11.

[0088] In this example, the tablet slot 114 is disposed on one side of the retaining bracket 11, preferably near the edge, top corner, or bottom corner of one side of the bracket body 112 of the retaining bracket 11. When detergent needs to be injected, the tablet slot 114 can be exposed after the user slightly pushes or pulls the panel 12. This helps to reduce the sliding distance of the panel 12.

[0089] In the example, the tablet slot 114 is positioned within the travel distance of the sliding structure 15. The panel 12 can open toward the side away from the tablet slot 114 to expose the tablet slot 114 and the connector at that end. Alternatively, the panel 12 can open toward the side closer to the tablet slot 114 to expose the connector, which is positioned at the end of the retaining bracket 11 away from the tablet slot 114.

[0090] In the example, such as Figures 1 to 5 As shown, the panel assembly 100 includes an injection tube 115 that can be connected to a tablet slot 114 to guide a cleaning tablet into a concealed water tank 16. The injection tube 115 is connected to the back side (i.e., rear side) of the tablet slot 114. An end of the injection tube 115 can extend into the concealed water tank 16 or detergent dispenser 162, and thus can guide detergent to slide into the concealed water tank 16 or detergent dispenser 162. The injection tube 115 is configured on the support body 112 of the retainer 11. In the example, as... Figure 35As shown, a tablet container basket 1151 is connected to an infusion tube 115. The tablet container basket 1151 is configured to hold cleaning tablets and ensure that at a given time, one cleaning tablet is immersed in water in a concealed water tank 16. A locking device 1152 is provided on the tablet container basket 1151 and is configured to lock the infusion tube 115 when it is closed by the tablet container basket 1151. A similar slot can be provided on the tablet container basket 1151, which can also be adjusted according to the wall thickness. The slot can be defined at different distances, allowing the tablet container basket 1151 to slide along different distances toward the infusion tube 115.

[0091] like Figures 13 to 16 As shown, the concealed water tank assembly according to the example of this disclosure includes a concealed water tank 16 and a panel assembly 100 as described in any of the foregoing examples.

[0092] The front of the concealed water tank 16 has a water tank window 161, and the mounting frame 111 of the retaining bracket 11 is connected to the water tank window 161.

[0093] The concealed water tank assembly according to this disclosure includes a concealed water tank 16 and a panel assembly 100. Regarding the structure, the construction and operating principle of the panel assembly 100, as described in the preceding paragraphs, are incorporated herein.

[0094] The concealed water tank 16 includes a tank window 161 or cover 18 connected to the concealed water tank 16, a panel assembly 100 connected to the tank window 161 or cover 18, a detergent dispenser 162 connected to the panel assemblies 100, 200, 300 for stacking cleaning tablets, and at least one flush valve connected to the panel assembly 100 via at least one flexible hose. The concealed water tank 16 can be installed in a cavity of the wall 17. The tank window 161 or cover 18 is connected to the top of the front side of the concealed water tank 16 and extends into a window in the wall 17. A retaining bracket 11 is connected to the tank window 161 via a connector that passes through a connection hole 113 in the retaining bracket 11.

[0095] The panel assembly 100 allows users to perform preventative maintenance without removing the panel assembly 12 from the retaining bracket 11 of the panel assembly 100. This improves maintenance efficiency and also ensures stable assembly of the panel 12 and the retaining bracket 11.

[0096] The examples in this disclosure further provide a method for manufacturing panel assemblies. Figure 17This is a flowchart of a method for manufacturing a panel assembly 100 according to Example 1 of this disclosure. Here, the panel assembly 100 manufactured by the method of this disclosure is any panel assembly 100 according to any example disclosed in this disclosure. The description of the panel assembly 100 as described in this disclosure is incorporated herein. The panel assembly 100 is configured to perform the operations, functions, or the like as described in this disclosure.

[0097] In action S101, the sliding structure 15 is formed on the support body 112 of the retaining bracket 11 and on the panel 12 of the panel assembly 100.

[0098] As mentioned above, in one example, such as Figures 4 to 12 As shown, the sliding structure 15 includes at least one guide groove 151 and a plurality of guide posts 152 that are slidably engaged with the at least one guide groove 151.

[0099] At least one guide groove 151 is provided on the support body 112 of the retaining bracket 11, and a plurality of guide posts 152 are provided on the panel 12. Alternatively, a plurality of guide posts 152 are provided on the support body 112 of the retaining bracket 11, and at least one guide groove 151 is provided on the panel 12.

[0100] In this example, the sliding structure 15 adopts a structure that combines at least one guide groove 151 and multiple guide posts 152, and has the following two combined installation methods.

[0101] In the first embodiment, at least one guide groove 151 is provided on the front side of the support body 112 of the retaining bracket 11, and a plurality of guide posts 152 are provided on the back side (i.e., rear side) of the panel 12. In the example, the plurality of guide posts 152 are integrated with the panel 12.

[0102] In the second embodiment, a plurality of guide posts 152 are disposed on the front side of the support body 112 of the retaining bracket 11, and at least one guide groove 151 is disposed on the back side (i.e., rear side) of the panel 12. In one example, the guide posts 152 are integrated with the support body 112 of the retaining bracket 11.

[0103] Depending on the desired direction of sliding, at least one guide groove 151 can be selected to extend laterally or vertically.

[0104] Multiple guide posts 152 are provided on the rear side of the panel 12, and two guide post flanges 1521A and 1521B are provided at the end of each guide post 152 and spaced apart, forming a limiting groove 1522 between the two guide post flanges 1521A and 1521B.

[0105] At least one guide groove 151 has its groove wall 1511 slidably fitted in the limiting groove 1522.

[0106] In the example, at least one guide groove 151 is provided on the support body 112 of the retaining bracket 11. The at least one guide groove 151 is an elongated through hole, and the at least one guide groove 151 is provided in the support body 112 of the retaining bracket 11, passing through the front surface and the rear surface of the support body 112 of the retaining bracket 11.

[0107] Guide posts 152 are disposed on the back side (i.e., rear side) of panel 12, and the positions of guide posts 152 correspond to the positions of corresponding guide grooves 151. First guide post flanges 1521A and second guide post flanges 1521B are spaced apart at the ends of each of the guide posts 152. In the example, guide post flanges 1521A and 1521B are substantially circular, and the two guide post flanges 1521A and 1521B are spaced apart along the axial direction of each of the guide posts 152 to form a limiting groove 1522 between the two guide post flanges 1521. In the example, each of the guide posts 152 and the two guide post flanges 1521A and 1521B of each of the guide posts 152 are made of plastic. The diameters of the two guide post flanges 1521A and 1521B are slightly larger than the width of their corresponding guide grooves 151.

[0108] In the example, such as Figure 6 As shown, each of at least one guide groove 151 has a groove wall 1511 including a groove wall recess 1512 configured to allow a post flange 1521 to pass through, such that a first guide post flange 1521A passes through the corresponding guide groove 151.

[0109] In step S102, panel 12 is slidably connected to support body 112 of retaining bracket 11 via sliding structure 15.

[0110] As described above, the ends of the plurality of guide posts 152 are inserted into corresponding guide grooves 151, and the guide posts 152 and the corresponding guide grooves 151 are assembled via a sliding connection.

[0111] In the assembled state of panel assembly 100, panel 12 is connected to retaining bracket 11, and guide post 152 slidably engages with at least one guide groove 151. In the normal state, friction exists between the guide post 152 and the groove wall 1511 of the at least one guide groove 151, allowing panel 12 to be positioned at a designated location. When a user slides panel 12, guide post 152 slides along guide groove 151, thereby opening panel 12.

[0112] When the guide post 152 and the guide groove 151 are assembled, the first guide post flange 1521A can extend through the corresponding guide groove 151, so that the groove wall 1511 of the guide groove 151 can be slidably fitted in the corresponding limiting groove 1522, which plays the role of limiting in the axial direction or from front to back.

[0113] In action S103, the injection tube 115 is connected to the tablet slot 114 of the retainer 11.

[0114] As mentioned above, such as Figures 1 to 5 As shown, the injection tube 115 is connected to the back side (i.e., rear side) of the tablet slot 114. The end of the injection tube 115 can extend into the concealed water tank 16 or detergent cartridge 62, and thus can guide detergent to slide into the concealed water tank 16 or detergent cartridge 162.

[0115] Because panel 12 is slidably connected to the support body 112 of retainer 11, panel 12 can slide relative to the support body 112 of retainer 11 to open panel assembly 100, thereby exposing tablet slot 114. When panel 12 is in the initial or closed state, panel 12 covers tablet slot 114. When the user slides panel 12 to open panel assembly 100, panel 12 moves away from tablet slot 114 to expose it to the user for dispensing a cleaning tablet. After dispensing a cleaning tablet, the user slides panel 12 in the opposite direction to close panel assembly 100, at which point panel 12 conceals tablet slot 114.

[0116] In action S104, at least one of the buttons 14, 141, 142, is installed in the panel 12 to trigger the flushing action of the concealed water tank 16.

[0117] As described above, at least one of the buttons 14, 141, 142, is disposed on the panel 12 and configured to press or trigger the pneumatic element 13. When the panel 12 is in the initial or closed state, the position of at least one of the buttons 14, 141, 142, corresponds to the position of the pneumatic element 13 in the front-to-back direction. By pressing at least one of the buttons 141, 142 of the panel assembly 100, the user can trigger the corresponding pneumatic element 13, and thus trigger at least one flush valve of the concealed water tank 16 to actuate the flushing action of the concealed water tank 16.

[0118] Example 2: like Figures 18 to 24As shown, Example 2 of this disclosure includes a panel assembly 200 for a concealed water tank 16, comprising a retaining bracket 21 connectable to the concealed water tank 16, the retaining bracket 21 having a tablet slot 211 through which cleaning tablets are inserted into the concealed water tank 16. The panel assembly 200 includes a panel 23 connected to the retaining bracket 21 in an assembled state. The assembled state of the panel assembly 200 includes a closed state and an open state. In the closed state, the panel 23 conceals the tablet slot 211 of the retaining bracket 21, and in the open state, the tablet slot 211 of the retaining bracket 21 is accessible for inserting cleaning tablets into the concealed water tank 16. In this example, the panel assembly 200 includes a sliding structure 26 to slidably connect the panel 23 to the retaining bracket 21 in the assembled state of the panel assembly 200, thereby allowing sliding movement of the panel 23 relative to the retaining bracket 21 to switch between the closed and open states of the panel assembly 200. In the example, panel assembly 200 includes an injection tube 22 that can be connected to a tablet slot 211 to guide a cleaning tablet into a concealed water tank 16. In one example, panel assembly 200 includes a button 24 and a leaf spring 25 that can be connected to the button 24.

[0119] The retainer 21 includes a tablet slot 211 configured to allow a user to add cleaning tablets to the concealed water tank 16. In this example, the cleaning tablets include cleaning tablets or cleaning balls that can be dissolved in water within the concealed water tank 16. When multiple cleaning tablets or cleaning balls are added to the concealed water tank 16 via the panel assembly 200, the cleaning tablets or cleaning balls can be stacked. Thus, a first cleaning tablet or cleaning ball at the bottom can be positioned below the waterline in the concealed water tank 16. As the bottom cleaning tablet or cleaning ball dissolves in water, a second cleaning tablet or cleaning ball positioned on top of the first cleaning tablet or cleaning ball can slide down into the water and dissolve. Therefore, it allows a user to conveniently add multiple cleaning tablets or cleaning balls to the concealed water tank 16 at once via the panel assembly 200, as the cleaning tablets or cleaning balls dissolve gradually.

[0120] In the example, the cleaning tablets include a liquid detergent that can be mixed with water in the concealed water tank 16.

[0121] The retainer 21 includes a connecting plate 212 disposed at the rear side of the tablet slot 211. Therefore, the rear side of the tablet slot 211 can be connected to the injection tube 22 via the connecting plate 212.

[0122] The connecting plate 212 includes a slot 2121, a groove 2122 disposed at the front end of the slot 2121, and an opening 2123 disposed at the rear end of the slot 2121. In the example, the slot 2121 is L-shaped. However, the shape of the slot 2121 is not limited to this. In the example, the retaining bracket 21 includes two connecting plates 212 spaced apart from each other. The injection tube 22 can be clamped between the two connecting plates 212. The width of the space between the two connecting plates 212 corresponds to the width of the injection tube 22.

[0123] The injection tube 22 includes a front end configured to connect to the rear side of the tablet slot 211 and a rear end configured to extend into the concealed water tank 16. Therefore, the injection tube 22 allows cleaning tablets to slide into the concealed water tank 16.

[0124] The injection tube 22 includes a curved portion 221 and a straight portion 222. The curved portion 221 includes the front end of the injection tube 22, and the straight portion 222 includes the rear end of the injection tube 22. The straight portion 222 lies flat downwards, allowing the cleaning tablet to enter the concealed water tank 16 under gravity. In one example, the curved portion 221 and the straight portion 222 may be integrally formed. In another example, the curved portion 221 and the straight portion 222 may be detachably connected to each other.

[0125] The injection tube 22 includes a protrusion 223 disposed on the outer surface of the front end of the injection tube 22. The shape of the protrusion 223 corresponds to the shape of the slot 2121, the groove 2122, and the opening 2123. When the injection tube 22 is connected to the rear side of the tablet slot 211, the user inserts the protrusion 223 into the opening 2123, and the slot 2121 guides the protrusion 223 into the groove 2122 under the influence of gravity. In the example, the injection tube 22 includes two protrusions 223 disposed on two outer surfaces of the front end of the injection tube 22.

[0126] Panel 23 includes at least one button 241, 242 of buttons 24 configured to move rearward relative to panel 23 to trigger at least one flush valve of concealed tank 16 to flush water from concealed tank 16 into the toilet bowl. In the example, panel 23 includes a button slot 231 configured to receive at least one button 241, 242. Button slot 231 protrudes from the rear surface of panel 23 and has a thickness corresponding to the thickness of at least one button 241, 242 of buttons 24. In the initial or unpressed state, at least one button 241, 242 of buttons 24, the front surface of at least one button 241, 242, and the front surface of panel 23 can be substantially coplanar. This configuration provides a clean appearance for panel assembly 200.

[0127] Panel 23 includes a leaf spring support 232, which is configured to support the leaf spring 25 and is disposed on the rear surface of panel 23. In the example, the leaf spring support 232 is disposed above the button slot 231. However, the position of the leaf spring support 232 is not limited to this.

[0128] At least one of the buttons 24, 241, 242, is configured to perform a flushing action, which includes a large flush and a small flush. In the example, the size of button 241 configured to perform a large flush may be larger than the size of button 242 configured to perform a small flush. When a user presses at least one of the buttons 241, 242, each of the at least one button 241, 241 moves rearward relative to panel 23. In the example, the buttons 24 may be individually connected to a pneumatic element (e.g., pneumatic element 13). A description of pneumatic element 13 is incorporated herein and therefore omitted. In the example, the number of buttons 24 can be set as needed. In another example, at least one button 241, 242 may be configured to the panel 23 to trigger a flush. In the example, the buttons 24 and the pneumatic element 13 may be connected via a flexible rod, flexible tube, or flexible hose. Therefore, movement of the buttons 24 together with the panel 23 will not obstruct the triggering of the pneumatic element 13.

[0129] The leaf spring 25 includes a horizontal portion 251 and two vertical portions 252 extending from both ends of the horizontal portion 251. The horizontal portion 251 is connected to a leaf spring support 232. The two vertical portions 252 are respectively connected to buttons 24. In this example, the leaf spring 25 may be made of a flexible plastic material. When a user presses at least one button 241, 242 of the buttons 24, at least one button 241, 242 returns to its initial state under the restoring force of the two vertical portions 252 of the leaf spring 25.

[0130] The sliding structure 26 includes at least one guide groove 261 disposed on the retaining bracket 21 and at least one guide post 262 disposed on the rear surface of the panel 23. In the assembled state of the panel assembly 200, at least one guide post 262 of the panel 23 slides within at least one guide groove 261 of the retaining bracket 21, causing the panel 23 to slide relative to the retaining bracket 21, thereby switching between a closed state and an open state of the panel assembly 200. The position of the at least one guide groove 261 corresponds to the position of the at least one guide post 262. The height of the at least one guide groove 261 corresponds to the height of the at least one guide post 262. The thickness of the at least one guide post 262 is greater than the thickness of the at least one guide groove 261.

[0131] With this configuration, at least one guide post 262 can be inserted into at least one guide slot 261 to pass through the front and rear surfaces of the retainer 21, and can slide within the at least one guide slot 261. Therefore, the panel 23 can be moved relative to the retainer 21 via the sliding structure 26, allowing the tablet slot 211 of the retainer 21 to be closed or opened. When the tablet slot 211 is open, the user can add cleaning tablets to the concealed water tank 16. When at least one guide post 262 is inserted from the front surface of the retainer 21 into the at least one guide slot 261, one end of the guide post 262 protrudes from the rear surface of the retainer 21.

[0132] In the example, at least one guide groove 261 includes two guide grooves 261 respectively disposed on the upper and lower ends of the retaining bracket 21. The two guide grooves 261 are arranged in parallel. Correspondingly, at least one guide post 262 includes two guide posts 262 respectively disposed on the upper and lower ends of the panel 23. The two guide posts 262 are arranged in parallel. This configuration can improve the stability of the panel 23 assembled on the retaining bracket 21, and can also improve the stability of the panel 23 when the guide posts 262 slide. However, the number and position of at least one guide groove 261 are not limited to this, and the number and position of at least one guide post 262 are not limited to this.

[0133] In the example, panel assembly 200 includes at least one slider cover 27. The at least one slider cover 27 includes a connecting portion 271 connected to the free end of at least one guide post 262 in the assembled state of panel assembly 200, and a retaining portion 272 integral with the connecting portion (271). In the assembled state of panel assembly 200, the retaining portion 272 is juxtaposed with the rear surface of retaining bracket 22 to retain at least one guide post 262 engaging with at least one guide groove 261. In the example, panel assembly 200 includes at least four slider covers 27, wherein two of the at least four slider covers 27 are connected to guide posts 262 disposed on the upper end of panel 23, and the other two are connected to guide posts 262 disposed on the lower end of panel 23. Each slider cover 27 includes a connecting portion 271 and a retaining portion 272. The connecting portion 271 is configured to connect to the guide post 262. The retaining portion 272 is configured to prevent the corresponding guide post 262 from disengaging from the corresponding guide groove 261. The height of the slider cover 27 is greater than the height of the guide groove 261.

[0134] When assembling the guide post 262 and the guide groove 261, the user can insert the guide post 262 from the front surface of the retaining bracket 21 into the guide groove 261, with one end of the guide post 262 extending from the rear surface of the retaining bracket 21. The user then attaches the slider cover 27 to the free end of the guide post 262 passing through the guide groove 261, abutting against the rear surface of the retaining bracket 21, thereby holding the guide post 262 in place.

[0135] The subject matter of this disclosure further provides a method for manufacturing panel assembly 200. Figure 25 This is a flowchart of a method for manufacturing a panel assembly 200 according to Example 2 of this disclosure. Here, the panel assembly 200 manufactured by this method includes a panel assembly according to any exemplary embodiment of this disclosure. The description of the panel assembly 200 as described in this disclosure is incorporated herein. The panel assembly 200 is configured to perform the operations, functions, or the like as described in this disclosure.

[0136] In action S201, the sliding structure 26 is formed on the retaining bracket 21 and the panel 23 of the panel assembly 200.

[0137] As described above, the sliding structure 26 includes at least one guide groove 261 disposed on the retaining bracket 21, and at least one guide post 262 disposed on the rear surface of the panel 23. The position of the at least one guide groove 261 corresponds to the position of the at least one guide post 262. The height of the at least one guide groove 261 corresponds to the height of the at least one guide post 262. The thickness of the at least one guide post 262 is greater than the thickness of the at least one guide groove 261.

[0138] In the example, at least one guide groove 261 includes two guide grooves 261 respectively disposed on the upper and lower ends of the retaining bracket 21. The two guide grooves 261 are arranged in parallel. Correspondingly, at least one guide post 262 includes two guide posts 262 respectively disposed on the upper and lower ends of the panel 23. The two guide posts 262 are arranged in parallel. This configuration can improve the stability of the panel 23 assembled on the retaining bracket 21, and can also improve the stability of the panel 23 when the guide posts 262 slide in their respective guide grooves 261. However, the number and position of at least one guide groove 261 are not limited to this, and the number and position of at least one guide post 262 are not limited to this.

[0139] The slider cover 27 includes four slider covers 27, two of which are configured to connect to guide posts 262 disposed at the upper end of the panel 23, and two slider covers are configured to connect to guide posts 262 disposed at the lower end of the panel 23. Each slider cover 27 includes a connecting portion 271 and a retaining portion 272. The connecting portion 271 is configured to connect to the guide post 262. The retaining portion 272 is configured to prevent the corresponding guide post 262 from disengaging from the corresponding guide groove 261. The height of the slider cover 27 is greater than the height of the guide groove 261.

[0140] In step S202, panel 23 is slidably connected to retaining bracket 21 via sliding structure 26.

[0141] As described above, at least one guide post 262 can be inserted into at least one guide slot 261 to pass through the front and rear surfaces of the retainer 21, and can slide within the at least one guide slot 261. Therefore, the panel 23 moves relative to the retainer 21 via the sliding structure 26, allowing the tablet slot 211 of the retainer 21 to be closed or opened. In the open state of the panel assembly 200, the user can access the tablet slot 211 to add cleaning tablets to the concealed water tank 16. When at least one guide post 262 is inserted from the front surface of the retainer 21 into at least one guide slot 261, one end of the guide post 262 protrudes from the rear surface of the retainer 21.

[0142] When assembling the guide post 262 and the guide groove 261, the user can insert the guide post 262 from the front surface of the retaining bracket 21 into the guide groove 261, with the free end of the guide post 262 protruding from the rear surface of the retaining bracket 21. The user can then attach the slider cover 27 to the free end of the guide post 262, allowing the slider cover 27 to abut against the rear surface of the retaining bracket 21, thereby holding the guide post 262 in place.

[0143] In action S203, the injection tube 22 is connected to the tablet slot 211 provided on the retaining bracket 21.

[0144] As described above, the injection tube 22 includes a front end configured to connect to the rear side of the tablet slot 211 and a rear end configured to extend into the concealed water tank 16. Therefore, the injection tube 22 can guide a cleaning tablet to slide into the concealed water tank 16.

[0145] The injection tube 22 includes a curved portion 221 and a straight portion 222. The curved portion 221 includes the front end of the injection tube 22, and the straight portion 222 includes the rear end of the injection tube 22. The straight portion 222 lies flat downwards onto the cleaning tablet to enter the concealed water tank 16 under gravity. In one example, the curved portion 221 and the straight portion 222 may be integrally formed. In another example, the curved portion 221 and the straight portion 222 may be detachably connected to each other.

[0146] The injection tube 22 includes a protrusion 223 disposed on the outer surface of the front end of the injection tube 22. The shape of the protrusion 223 corresponds to the shape of the slot 2121, the groove 2122, and the opening 2123. When the injection tube 22 is connected to the rear side of the tablet slot 211, the user can insert the protrusion 223 into the opening 2123, and the slot 2121 can guide the protrusion 223 into the groove 2122 under the action of gravity. In the example, the injection tube 22 includes two protrusions 223 disposed on two outer surfaces of the front end of the injection tube 22.

[0147] In action S204, at least one of the buttons 24, 241, 242, is installed in the panel 23.

[0148] As described above, button 24 includes two buttons 241 and 242, respectively configured to perform a large rinse and a small rinse. The size of button 241, configured to perform a large rinse, may be larger than the size of button 242, configured to perform a small rinse. When the user presses button 24, button 24 can move rearward relative to panel 23. In this example, buttons 24 may be connected to pneumatic components (e.g., pneumatic component 13). A description of pneumatic component 13 is incorporated herein and therefore omitted. In this example, the number of buttons 24 can be set as needed. In another example, only one button 24 may be configured to trigger the rinse.

When tablet slot 362 is exposed, a user can add at least one cleaning tablet to concealed water tank 16.

[0150] The retaining bracket 31 may have an internal space or internal slot configured to accommodate other elements of the panel assembly 300 or to allow other elements of the panel assembly 300 to pass through the interior of the retaining bracket 31.

[0151] The retainer 31 includes an opening 311 disposed on its rear surface to allow the injection tube 32 to be inserted into the internal space or internal slot of the retainer 31. The width and height of the opening 311 correspond to the width and height of the injection tube 32. The retainer 31 includes a slot 313 configured to allow the spring assembly 35 to pass through.

[0152] The retainer 31 includes two spaced-apart connecting plates 312 configured to connect an injection tube 32. The injection tube 32 can be clamped between the two connecting plates 312. The width of the space between the two connecting plates 312 corresponds to the width of the injection tube 32. In one example, the injection tube 32 may be integrally formed with the two connecting plates 312. In another example, the injection tube 32 and the two connecting plates 312 may be detachably connected to each other.

[0153] The injection tube 32 includes a front end and a rear end, the front end being configured to be connected to the rear surface of the panel 33, and the rear end being configured to extend into the concealed water tank 16 (e.g., the concealed water tank 16 as described above). Therefore, the injection tube 32 can guide the cleaning tablet to slide into the concealed water tank 16.

[0154] The injection tube 32 includes a curved portion 321 and a straight portion 322. The curved portion 321 includes the front end of the injection tube 32, and the straight portion 322 includes the rear end of the injection tube 32. The straight portion 322 lies downwards, allowing the cleaning tablet to enter the concealed water tank 16 under gravity. In one example, for instance, when the straight portion 322 is integrally formed with the two connecting plates 312, the curved portion 321 and the straight portion 322 can be detachably connected to each other. In another example, for instance, when the injection tube 32 and the two connecting plates 312 are detachably connected to each other, the curved portion 321 and the straight portion 322 can be integrally formed.

[0155] Panel 33 includes at least one button 341, 342 of buttons 34, wherein at least one button 341, 342 is configured to move rearward relative to panel 33 to trigger at least one flush valve of concealed tank 16 to perform toilet flushing. In the example, panel 33 includes a central space 331 configured to receive buttons 34. In the initial or unpressed state of buttons 34, the front surface of buttons 34 and the front surface of panel 33 can be substantially coplanar. This configuration provides a clean appearance for panel assembly 300.

[0156] Panel 33 includes a post 332 on its rear surface to connect retaining bracket 31 to panel 33 in the assembled state of panel assembly 300. The post 332 is disposed on the rear surface of panel 33 and configured to guide retaining bracket 31 toward the rear surface of panel 33 when the user connects retaining bracket 31 and panel 33. In the assembled state of panel assembly 300, the front surface of retaining bracket 31 contacts the rear surface of panel 33, and the upper surface of panel 33 can rest on the post 332.

[0157] In the example, column 332 includes two columns 332 disposed on the upper edge of panel 33. In the example, column 332 includes four columns 332, wherein two of the four columns 332 are disposed on the upper edge of panel 33, and the other two columns 332 are disposed on the lower edge of panel 33.

[0158] Button 34 includes two buttons 341 and 342, respectively configured to perform a small rinse and a large rinse. The size of button 341, configured to perform a small rinse, may be smaller than the size of button 342, configured to perform a large rinse. When the user presses button 34, button 34 can move rearward relative to panel 33. In this example, button 34 may be connected to a pneumatic element (e.g., pneumatic element 13). A description of pneumatic element 13 is incorporated herein and therefore omitted. In this example, the number of buttons 34 can be set as needed. In another example, only one button 34 may be configured to trigger the rinse. In this example, button 34 and pneumatic element 13 may be connected via a flexible rod, flexible tube, or flexible hose. Therefore, movement of button 34 will not obstruct the triggering of pneumatic element 13.

[0159] In the example, panel assembly 300 includes at least one pivoting component 37 connected to at least one button 341, 342 to pivot the button 341, 342 relative to panel 33, thereby toggling between a closed and open state of panel assembly 300. One of the buttons 34 (e.g., button 341) can pivot relative to panel 33 via pivoting component 37 such that the tablet slot 362 of retainer 31 can be covered or exposed by button 341. When tablet slot 362 is exposed, a user can add cleaning tablets to concealed water tank 16. In this example, button 341 can pivot relative to panel 33. In another example, button 342 can pivot relative to panel 33.

[0160] When the buttons 34 are in their initial positions, the front surface of the buttons 34 and the front surface of the panel 33 can be substantially aligned on the same plane. The buttons 34 can be held in their initial positions by the spring assembly 35.

[0161] Each of the spring assemblies 35 includes a spring post 351, a spring 352, and a cap 353. In this example, there are four spring assemblies 35. However, the number of spring assemblies 35 is not limited to this.

[0162] In this example, the spring posts 351 include two spring posts 351 disposed on the rear surface of the button 342 and two spring posts 351 disposed on the rear surface of the connecting protrusion 36. The length of the spring posts 351 may correspond to or may be greater than the thickness of the retaining bracket 31.

[0163] Each of the springs 352 is fitted onto a corresponding spring post 351. The springs 352 are configured to be compressed in response to the rearward movement of the button 34 when the user presses it. The springs 352 are also configured to provide a restoring force to the button 34, allowing the button 34 to move forward to its initial position.

[0164] A cover 353 is disposed at the rear end of the spring post 351. The diameter of the cover 353 is larger than the diameter of the slot 313 of the retaining bracket 31. In the example, the panel assembly 300 includes a connecting protrusion 36 that can be attached to the rear surface of the panel 33 such that the front surface of the connecting protrusion 36 is located behind the rear surface of at least one button 341, 342 pivotally connected to the panel 33. When installing the panel assembly 300, a user can attach the spring post 35 to the rear surface of the button 342 and the rear surface of the connecting protrusion 36, and can sleeve the spring 352 onto the spring post 351. The user can then insert the rear end of the spring post 35 into the slot 313 of the retaining bracket 31 and attach the cover 353 to the rear end of the spring post 351.

[0165] When the buttons 34 are in their initial positions, the cover 353 contacts the rear surface of the retaining bracket 31 to prevent the buttons 34 from moving forward relative to the panel 33. When the user presses the button 34, the button 34 and the spring post 351 can move rearward relative to the panel 33. Therefore, the rear end of the spring post 351 can extend from the rear surface of the retaining bracket 31.

[0166] The connecting protrusion 36 includes a front surface configured to align with or abut from the rear surface of the panel 33. The connecting protrusion 36 may have an internal space or internal slot configured to accommodate other elements of the panel assembly 300 or to allow other elements of the panel assembly 300 to pass through the interior of the connecting protrusion 36. The connecting protrusion 36 is aligned with the button 341 in a front-to-back direction.

[0167] The connecting protrusion 36 includes an opening 361 disposed on the rear surface of the connecting protrusion 36, and the opening 361 is configured to allow the injection tube 32 to be inserted into the internal space or internal slot of the connecting protrusion 36. The width and height of the opening 361 correspond to the width and height of the injection tube 32.

[0168] The connecting protrusion 36 includes a tablet slot 362 disposed on its front surface to allow a user to add cleaning tablets to the concealed water tank 16. In the assembled state of the panel assembly 300, the tablet slot 362 of the connecting protrusion 36 is located behind the rear surface of at least one button (341, 342) pivotally connected to the panel (33). The width and height of the tablet slot 362 correspond to the width and height of the infusion tube 32. In this example, the detergent may include cleaning tablets or cleaning balls that can be dissolved in water in the concealed water tank 16. When multiple cleaning tablets or cleaning balls are added to the concealed water tank 16 via the panel assembly, the cleaning tablets or cleaning balls can be stacked. Thus, the bottom first cleaning tablet or first cleaning ball can be positioned below the waterline in the concealed water tank 16. When the bottom cleaning tablet or cleaning ball is dissolved in water, a second cleaning tablet or second cleaning ball disposed on the first cleaning tablet or first cleaning ball can slide down into the water and be dissolved. Therefore, it allows users to easily add multiple cleaning tablets or cleaning balls to the concealed water tank 16 at once via the panel assembly 300, as the cleaning tablets or cleaning balls can gradually dissolve.

[0169] In another example, the detergent may also include other types of detergents (such as liquid detergents) that can be mixed with water in the concealed water tank 16.

[0170] When the injection tube 32 is installed, the user can insert the front end of the injection tube 32 into the openings 311 and 361, and then connect the front end of the injection tube 32 to the tablet slot 362.

[0171] When button 341 is in its initial position, the front surface of connecting protrusion 36 can be aligned with the rear surface of panel 33. When the user presses button 341, button 341 and connecting protrusion 36 can move rearward relative to panel 33. Therefore, the front surface of connecting protrusion 36 can disengage from the rear surface of panel 33.

[0172] Pivoting assembly 37 includes two pivoting assemblies 37. The number of pivoting assemblies 37 is not limited thereto. Each of the pivoting assemblies 37 includes a hinge 371 and a pivot pin 372. The hinge 371 is configured to connect the edge of at least one button 341, 342 to the edge of the panel 33. The hinge 371 includes a slot configured to receive the pivot pin 372. The pivot pin 372 is configured to insert into the slot of the hinge 371. At least one button 341, 342 rotates about the pivot pin 372, thereby allowing it to be opened or closed by a user.

[0173] The leaf spring 38 includes two leaf springs 38. The number of leaf springs 38 is not limited to this. Each of the leaf springs 38 includes a horizontal portion 381 and a vertical portion 382 extending from the horizontal portion 381. The horizontal portion 381 is connected to a corresponding hinge 371. The vertical portion 382 is connected to the rear surface of the connecting protrusion 36. The leaf springs 38 may be made of a flexible plastic material. When the user releases the button 341, the button 341 can return to its initial position under the restoring force of the leaf springs 38.
