Its structure, as shown in Chinese utility model patent document CN216156725U, consists of an air tube and one or two air bladders. An air pump inflates the air bladders, and once the bladders are full, the pneumatic flush valve performs the flushing action.

[0003] In existing technologies, air is typically inflated into the airbag by pressing a button and using an inflation device integrated on the button. Existing technologies also use mechanical mechanisms to drain water, which hinders the realization of electrification. Utility Model Content

[0063] Example

[0064] This embodiment provides a drain valve control device (toilet drain valve control device), such as Figure 1 As shown, it includes:

[0065] The outer shell consists of an upper outer shell 1 and a lower outer shell 2;

[0066] A sealing element 3 is disposed between the upper outer shell 1 and the lower outer shell 2 to seal the gap between them;

[0067] An electrical wire (not shown in the figure) exits from the wire outlet 10 of the casing;

[0068] Air pump 5, the air pump 5 having an air pump inlet 51 and an air pump outlet 52;

[0069] The solenoid valve 6 has a gas inlet 61, a first gas outlet 62, and a second gas outlet 63. The gas inlet 61 is connected to the gas outlet 52 of the air pump 5. The solenoid valve 6 has a first state in which the gas inlet 61 is connected to the first gas outlet 62 and a second state in which the first gas outlet 62 is connected to the second gas outlet 63.

[0070] The wire is used to supply power to the air pump 5 and the solenoid valve 6. The air pump 5 starts to work after being energized, and the solenoid valve 6 switches between a first state and a second state after being energized.

[0071] The drain valve control device of this application can convert electrical signals into pneumatic signals. After the electrical signal is input by wire, the working state of the air pump 5 and the solenoid valve 6 is controlled. The air pump 5 sprays gas and injects it into the air bag of the pneumatic drain valve after passing through the solenoid valve 6. Inflation can be achieved without the operator pressing a button. Only an electrical signal needs to be input by wire, which provides the possibility of electrically controlling the pneumatic drain valve.

[0072] Furthermore, solenoid valve 6 is a normally open solenoid valve, such as... Figure 5 As shown, the solenoid valve 6 is in the first state when not powered on and in the second state when powered on. In the first state, the gas inlet 61 of the solenoid valve 6 is connected to the first gas outlet 62, and in the second state, the first gas outlet 62 and the second gas outlet 63 are connected. When the solenoid valve 6 is de-powered, the gas inlet 61 is disconnected from the first gas outlet 62, and the first gas outlet 62 and the second gas outlet 63 are connected, so that the gas in the trachea can be discharged.

[0073] Furthermore, a hook 21 is provided on the back of the lower housing 2 to facilitate installation.

[0074] Furthermore, the gas inlet 61 is connected to the air pump outlet 52 via a connecting pipe 7. The connecting pipe 7 is made of rubber, thereby maintaining a certain degree of airtightness when connected to both the gas inlet 61 and the air pump outlet 52.

[0075] The first gas outlet 62 is located within the gas outlet mounting through hole of the transition connection 13. The gas outlet mounting through holes are located on both sides of the transition connection 13, including a first gas outlet mounting through hole 211 and a second gas outlet mounting through hole 212. In use, if only one gas outlet mounting through hole is used, the unused gas outlet mounting through hole is sealed by the seal 3 (the seal 3 forms an enlarged end here). When two solenoid valves 6 are provided, both gas outlet mounting through holes will be used simultaneously.

[0076] The top of the housing is provided with a top outlet through hole, and a second gas outlet 63 is located within the top outlet through hole. For example, a first top outlet 213 and a second top outlet 214 are selected for the second gas outlet 63 to extend out. In use, only one top outlet through hole is used, and the unused top outlet through hole is sealed by a seal 3. When two solenoid valves 6 are provided, both top outlet through holes will be used simultaneously.

[0077] Furthermore, a first screw hole 101 and a positioning post 102 are provided on the outer edge of the upper outer shell 1 or the lower outer shell 2. Correspondingly, a second screw hole 201 and a positioning hole 202 are provided on the outer edge of the lower outer shell 2 or the upper outer shell 1. The screws located in the first screw hole 101 and the second screw hole 201, as well as the positioning post, all pass through the seal 3.

[0078] The other end of the wire connects to the sensor panel or smart toilet seat. The operator presses the button on the sensor panel or smart toilet seat, or uses a remote control to control the sensor panel or smart toilet seat, causing the corresponding circuit inside the sensor panel or smart toilet seat to send a signal, which activates the air pump 5 and the solenoid valve 6. Normally, after the air pump 5 has been operating for a set period of time, the solenoid valve 6 will then activate to switch the air path.

[0079] Furthermore, the upper outer shell 1 and the lower outer shell 2 form a first chamber 11 and a second chamber 12, with a transition connection 13 between the first chamber 11 and the second chamber 12. The air pump 5 is located in the first chamber 11, and the solenoid valve 6 is located in the second chamber 12. The air passage connection between the air pump 5 and the solenoid valve 6 is located on the side wall of the transition connection 13.

[0080] like Figure 6 As shown, one end of the air pump 5 has an air pump inlet 51 and an air pump outlet 52. The bottom has a connector 53 for connecting to an electrical wire.

[0081] Furthermore, a conical protrusion 23 is formed on the inner wall of the outer shell, and the conical protrusion 23 has a vent hole 22 passing through the outer shell in the middle. The air pump inlet 51 is connected to the conical protrusion 23. When the air pump 5 is working, it can draw gas from outside the outer shell into the air pump 5.

[0082] like Figure 5As shown, the conical protrusion 23 is specifically formed on the lower outer shell 2 and is connected to the air pump inlet 51 via a rubber pipe. Since the entire outer shell of the drain valve control device in this embodiment is sealed by a sealing element, the conical protrusion 23 connects to the outside of the outer shell, and the gas can be drawn from the outside to prevent the problem of gas extraction not being smooth due to the extraction of gas from inside the outer shell.

[0083] Several positioning blocks 24 are also provided inside the lower outer casing 2 to fix the components inside the casing.

[0084] The first gas outlet 62 is connected to the pneumatic drain valve in the toilet via a gas pipe, thereby enabling the pneumatic drain valve to perform relevant actions.

[0085] It should be noted that the various openings and through holes formed between the upper outer shell 1 and the lower outer shell 2 also need to be sealed. The sealing element 3 is made of rubber and is formed in the shape of the opening or through hole.

[0086] The diagram in this application shows only one solenoid valve 6. However, as an optional implementation, a second solenoid valve 6 can be connected in parallel within the second chamber 12. The gas inlet 61 of the second solenoid valve 6 is also connected to the air outlet 52 of the air pump 5. The second solenoid valve 6 operates in the opposite state to the first solenoid valve 6; that is, when the first solenoid valve 6 is in the first state, the second solenoid valve 6 is in the second state, and vice versa. The two solenoid valves 6 independently achieve half-discharge and full-discharge (the amount of water drained from the toilet tank).

[0087] Based on the above-described preferred embodiments according to this application, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this application. The technical scope of this application is not limited to the contents of the specification, but must be determined according to the scope of the claims.
