Abstract
Description
Technical Field
[0001] This utility model relates to the field of toilet accessories, specifically to a flushing module and a toilet tank. Background Technology
[0002] Toilets, also known as commodes, make people's lives more convenient. However, because toilets are installed on the ground and have limited height, people need to bend over to press the mechanical switch to flush after use, which is inconvenient and affects comfort.
[0003] Therefore, existing smart toilets use a seat-leaving sensor to detect whether someone is using the toilet and output a signal after the user gets up and leaves. The controller (i.e., the seat-leaving flush module) receives the signal and controls the drain valve to flush the toilet, thus achieving automatic flushing after the user leaves the seat.
[0004] When the drain valve adopts a pneumatic structure, the off-seat flushing module needs to output an air source to control the pneumatic drain valve. Therefore, an air pipe connector needs to be designed on the housing of the off-seat flushing module to connect the external air pipe. Existing air pipe connectors are generally integrally injection molded with the housing, and the material of the air pipe structure is the same as that of the housing (both are plastic), or metal connectors are integrally injection molded with the housing through pre-embedding. These all have a drawback: when the air pipe connector is damaged, the entire housing needs to be replaced, which is costly. However, if the housing and air pipe connector are separated, there is a risk of poor airtightness, allowing external moisture to enter the housing of the off-seat flushing module and damage the internal sensing and control module. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides an off-seat flushing module and a toilet tank.
[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0008] Furthermore, the diameter of the mounting perforation is smaller than the diameter of the mounting slot. The air pipe connector includes an inner pipe section, an outer pipe section, and an abutment boss located between the inner pipe section and the outer pipe section. The outer pipe section passes through the mounting perforation to the outside of the housing. The inner pipe section of the air pipe connector passes through the air outlet end of the air guide channel of the sealing filler block. The abutment boss is confined between the filling protrusion and the inner wall of the housing.
[0009] Furthermore, the tracheal connector is a rigid metal connector.
[0010] Furthermore, the end of the tracheal connector extending out of the housing has a radially protruding inverted buckle structure.
[0011] Furthermore, the housing includes a bottom shell and a top cover, the top cover sealingly covering the opening of the bottom shell to form a sealed mounting cavity, and the sensing control module, air pump and sealing filler block are all disposed within the mounting cavity.
[0012] Furthermore, the mounting slots and mounting perforations are formed on the top cover.
[0013] Furthermore, the sealing filler block is provided with a straight through hole on one opposite side. The straight through hole serves as one section of the air guide channel. A sealing protrusion protrudes from the inner wall of the housing opposite to the mounting slot. The sealing protrusion is sealed and inserted into one opening of the straight through hole. The other opening of the straight through hole serves as the air outlet of the air guide channel.
[0014] Furthermore, an air tube bayonet is integrally formed on the outer side of the housing.
[0015] A toilet tank includes a tank body, a pneumatic drain valve, and an off-seat flushing module disposed within the tank body; the off-seat flushing module is the off-seat flushing module described above; the sensor control module of the off-seat flushing module is used to connect to an off-seat sensor to receive signals emitted by the off-seat sensor, and the air pipe connector is externally connected to an air pipe and connected to the pneumatic drain valve through the air pipe.
[0016] Furthermore, the outer side of the housing of the off-seat flushing module is provided with a quick-connect structure, which is connected to the inner wall of the water tank.
[0017] The technical solution provided by this utility model has the following beneficial effects:
[0018] The housing and air pipe connector are separated and assembled, allowing for individual replacement and saving costs. Simultaneously, a sealing filler block structure is added. This block seals the mounting slot with its filling protrusions, achieving an internal and external seal. This prevents moisture from entering the housing through the gap between the air pipe connector and the housing, resulting in a superior sealing effect and improved product reliability.

These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0029] Reference Figures 1 to 5As shown, this embodiment provides an off-seat flushing module 1, including an air pipe connector 20, a housing 10, and a sensing control module 41, an air pump 42, and a sealing filler block 30 disposed within the housing 10. The sensing control module 41 drives and connects to the air pump 42. Specifically, the sensing control module 41 is prior art and is used to connect to an off-seat sensor to receive signals emitted by the off-seat sensor. The housing 10 is provided with a mounting slot 102 located within the housing 10 and a mounting through hole 101 connecting the mounting slot 102 and extending to the outside. The sealing filler block 30 is disposed within the housing 10 and has a filling protrusion 31 that seals and fills the mounting slot 102. The sealing filler block 30 is provided with an air guide channel 32. The first end of the air guide channel 32 is connected to the air pump 42, and the second end of the air guide channel 32 is formed on the filling protrusion 31. The air pipe connector 20 passes through the mounting through hole 101 and is sealed and inserted into the second end of the air guide channel 32.
[0030] The solution proposed in this application separates the housing 10 from the air pipe connector 20 and assembles them, allowing for individual replacement and saving costs. Simultaneously, the addition of a sealing filler block 30, which seals the mounting slot 102 through the filling protrusion 31, achieves internal and external sealing. This prevents moisture from entering the housing 10 through the gap between the air pipe connector 20 and the housing 10, resulting in a good sealing effect and improved product reliability.
[0031] Continue to refer to Figure 6 As shown, this embodiment also provides a toilet tank, including a tank body 2, a pneumatic drain valve disposed in the tank body 2, and the aforementioned off-seat flush module 1; the sensing control module 41 of the off-seat flush module 1 is used to connect to an off-seat sensor to receive the signal emitted by the off-seat sensor, and the air pipe connector 20 is externally connected to an air pipe and connected to the pneumatic drain valve through the air pipe.
[0032] The working principle is as follows: The external seat-leaving sensor is installed on the toilet seat. When it senses that the user has gotten up, it outputs a signal to the sensing control module 41 of the seat-leaving flushing module 1. The sensing control module 41 controls the air pump 42 to work. The airflow output by the air pump 42 passes through the air guide channel 32 of the sealed filling block 30, the air pipe connector 20 and the air pipe in sequence and flows into the pneumatic drain valve, thereby driving the pneumatic drain valve to perform drainage work.
[0033] Preferably, in this embodiment, the diameter of the mounting perforation 101 is smaller than the diameter of the mounting slot 102. The tracheal connector 20 includes an inner pipe section 21, an outer pipe section 23, and an abutment boss 22 located between the inner pipe section 21 and the outer pipe section 23. The outer pipe section 23 passes through the mounting perforation 101 to the outside of the housing 10. The inner pipe section 21 of the tracheal connector 20 passes through the air outlet end of the air guide channel 32 of the sealing filler block 30. The abutment boss 22 is confined between the filling protrusion 31 and the inner wall of the housing 10. In this way, not only is sealing achieved, but the tracheal connector 20 is also well fixed, achieving a stable connection through a simple structure. When disassembling the tracheal connector 20, simply pull the filling protrusion 31 of the sealing filler block 30 out of the mounting slot 102.
[0034] More preferably, the endotracheal connector 20 is a rigid metal connector. The metal material has sufficient hardness, allowing the wall of the endotracheal connector 20 to be made very thin. In this embodiment, the endotracheal connector 20 is specifically a copper connector, which is low in cost, lightweight, and not corroded by moisture.
[0035] The end of the tracheal connector 20 extending out of the housing 10 (i.e. the end of the external pipe section 23) has a radially protruding inverted buckle structure 24. When connecting an external tracheal pipe, it can open and fix the tracheal pipe, forming an interference fit with the tracheal pipe and improving the reliability of the connection.
[0036] The housing 10 includes a bottom shell 12 and a top cover 11. The top cover 11 seals over the opening of the bottom shell 12 to form a sealed mounting cavity 100. The sensing control module 41, the air pump 42, and the sealing filler block 30 are all disposed within the mounting cavity 100. The mounting slot 102 and the mounting through hole 101 are formed in the top cover 11, making it easy to manufacture. Specifically, when the bottom shell 12 and the top cover 11 are closed, the gap can be filled and sealed by the sealing ring 15. This is prior art and will not be described in detail here.
[0037] The sealing filler block 30 is a rubber block with a certain degree of elasticity, which provides a good sealing effect and will not collapse and block the air passage 32.
[0038] For ease of processing, the sealing filler block 30 is provided with a straight through hole running through one opposite side, meaning that a straight through hole is directly made in the sealing filler block during processing. During assembly, the straight through hole serves as one section of the air guide channel, and a sealing protrusion 121 protrudes from the inner wall of the housing (i.e., the inside of the bottom shell 12) opposite to the mounting slot 102. The sealing protrusion 121 is sealed and inserted into one opening of the straight through hole, and the other opening of the straight through hole serves as the air outlet of the air guide channel 32. Of course, other embodiments are not limited to this.
[0039] Preferably, in this embodiment, the number of air pipe connectors 20 is four, namely two air inlet connectors and two air outlet connectors; of the two air inlet connectors, one is used to connect to the full exhaust button of the operation panel (defined as the first air inlet connector), and the other is used to connect to the half exhaust button of the operation panel (defined as the second air inlet connector); of the two air outlet connectors, one is used to connect to the half exhaust drive of the pneumatic drain valve, and the other is used to connect to the full exhaust drive of the pneumatic drain valve. It also includes two two-inlet, one-outlet switching valves 43. The air pump 42 has two air outlets (a full exhaust outlet and a half exhaust outlet), which are respectively connected to the first inlet of the two switching valves 43. The two air inlet connectors are respectively connected to the second inlet of the two switching valves 43 through the air guide channel 32 of the sealing filler block 30. Specifically, the second inlet of each switching valve 43 is connected to a sealing filler block 30, and an air inlet connector is connected through the sealing filler block 30; the outlets of the two switching valves 43 are connected to the same sealing filler block 30, and each is connected to an air outlet connector through the sealing filler block 30. Thus, each switching valve 43 is connected to both the air source of the air pump 42 and the air source of the manual button; for example, the first switching valve 43 is connected to the full exhaust end of the air pump 42 and the first air inlet connector, and the second switching valve 43 is connected to the half exhaust end of the air pump 42 and the second air inlet connector; the final air circuit connection diagram is shown below. Figure 7 As shown.
[0040] The two switching valves 43 are connected to the air pump 42 via normally closed inlets and to the air inlet connector via normally open inlets. The structure of the switching valves 43 is existing technology and will not be described in detail here. The two switching valves 43 are connected to the sensing control module 41, which controls the switching of the two inlets of the switching valves 43. The specific working principle is as follows: When the full drain button or half drain button is pressed manually, the corresponding switching valve 43 outputs gas and drives the flushing valve to perform full or half drain operation. When flushing is performed using the seat-off sensor, the sensing control module 41 receives the signal from the seat-off sensor and controls the air pump 42 to work. The air pump 42 outputs gas from its full or half drain end. At the same time, the sensing control module 41 controls the corresponding switching valve 43 to switch the air path, allowing the air pump 42 to output airflow. In this way, both manual pressing for drainage and water discharge can be performed by sensing water discharge through the seat-off sensor can be performed.
[0041] Of course, in other embodiments, the number of air pipe connectors 20 and the arrangement of internal air passages are not limited to this; for example, only an air passage controlled by the air pump 42 may be provided.
[0042] Specifically, the outer side of the housing 10 is also integrally formed with a trachea bayonet 13 for binding the trachea and restricting the layout of the trachea.
[0043] Meanwhile, a quick-connect structure 14 is provided on the outer side of the housing 10 of the off-seat flushing module 1, and is connected to the inner wall of the water tank 2 through the quick-connect structure 14, realizing the quick installation and disassembly of the off-seat flushing module 1 and the water tank 2. Specifically, the quick-connect structure 14 can adopt a structure in the prior art, such as a snap-fit structure.
[0044] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
