Detailed implementation mode

[0034] To make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Usually, the components of the embodiments of the present utility model described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed present utility model, but merely represents the selected embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0036] As Figure 1 — Figure 14 shown in the embodiment.

[0037] A single air pump 2 realizes a double-pulse control box, including a fixing frame 1. An installation part is provided in the middle of the fixing frame 1, and at least two connection parts are arranged on the outer periphery of the installation part; an air pump 2 is fixedly installed on the installation part; a circuit board box 3 is installed on one of the connection parts and is arranged side by side with the air pump 2; an air path assembly is installed on the other connection part, and the air path assembly conveys the gas from the air pump 2 to different air paths.

[0038] The two connection parts are respectively located on both sides of the installation part, and the circuit board box 3 and the air path assembly are correspondingly located on both sides of the air pump 2. Refer to Figures 1 to 5 As shown, connection parts are arranged on both the left and right sides or the front and back sides of the installation part. Through the air path assembly and the circuit board box 3 installed on the two connection parts, they can be arranged side by side with the air pump 2, and the air pump 2 is installed on the installation part located in the middle of the two connection parts. Thus, the installation space of the fixing frame 1 is greatly improved, the distance between the air pump 2, the circuit board box 3 and the air path assembly is reduced, the structure is more compact, the space occupation is greatly reduced, and the control box can be installed in a narrow space.

[0039] It further includes a three-way solenoid valve 5. The air inlet of the three-way solenoid valve 5 is connected to the outlet of the air pump 2, and the air outlet of the three-way solenoid valve 5 is communicated with the air path assembly. The three-way solenoid valve 5 controls the gas from the air pump 2 to be delivered to different air paths of the air path assembly.

[0040] An air path joint 4 is further arranged between the three-way solenoid valve 5 and the outlet of the air pump 2. The three-way solenoid valve 5 and the air pump 2 are communicated through the air path joint 4.

[0041] Refer to Figures 1 to 5 As shown, the air path joint 4 is located between the air pump 2 and the air inlet of the three-way solenoid valve 5. The outlet of the air pump 2 is arranged downward, that is, both the air path joint 4 and the three-way solenoid valve 5 are located below the air pump 2, so that no space is occupied in the left-right direction or the front-back direction.

[0042] In this embodiment, the air inlet of the three-way solenoid valve 5 is connected to the outlet of the air pump 2 through the air path joint 4. Then, the two air outlets of the three-way solenoid valve 5 are respectively connected to the air path channels of the air path assembly. Specifically, the first air outlet pipe and the second air outlet pipe in the air path assembly are connected to the two air outlets of the three-way solenoid valve 5, so that the gas from the air pump 2 is switched and delivered to the first air outlet pipe or the second air outlet pipe through the three-way solenoid valve 5.

[0043] In this embodiment, the initial state of the three-way solenoid valve 5 can be to open the opening connected to the first air outlet pipe, and then switch to open the opening connected to the second air outlet pipe when needed. In practice, it can be designed according to needs and is not limited here.

[0044] The air path assembly includes a first air outlet pipe and a second air outlet pipe. A deflation switching device 6 is installed between the first air outlet pipe and the second air outlet pipe. The deflation switching device 6 is used to discharge the gas in the first air outlet pipe or the second air outlet pipe.

[0045] In this embodiment, the first air outlet pipe is connected to the full-discharge driving device of the toilet, and the second air outlet pipe is connected to the half-discharge driving device of the toilet. That is, when the three-way solenoid valve 5 switches the air path to the first air outlet pipe, the gas of the air pump 2 will be delivered to the full-discharge driving device through the guidance of the first air outlet pipe, and then the toilet realizes the full-drainage operation. Correspondingly, if the three-way solenoid valve 5 switches the air path to the second air outlet pipe, the gas from the air pump 2 will be delivered to the half-discharge driving device through the guidance of the second air outlet pipe, and then the toilet realizes the half-drainage operation.

[0046] The air release switching device 6 includes an exhaust switching valve. Two air inlets of the exhaust switching valve are respectively connected to the first air outlet pipe and the second air outlet pipe. The exhaust switching valve discharges the gas in the first air outlet pipe or the second air outlet pipe. The exhaust switching valve includes a valve body 61 and a valve core 62 respectively cooperating with the two air inlets of the valve body 61. The valve body 61 further includes an air release port 63 communicating with the two air inlets.

[0047] Refer to Figures 1 to 6 As shown, the exhaust switching valve can freely switch whether to discharge the gas in the first air outlet pipe or the second air outlet pipe. After the exhaust switching valve discharges the gas in the first air outlet pipe, the gas in the full discharge driving device is discharged, and then the full drainage state can be released. Correspondingly, after the exhaust switching valve discharges the gas in the second air outlet pipe and the gas in the semi-discharge driving device is discharged, the semi-drainage state can be released.

[0048] The valve core 62 is a one-way valve core for enabling one-way communication between the first air pipe 7 and the air release port 63 or between the second air pipe 8 and the air release port 63, or the valve core 62 is a sliding valve core for controlling the communication between the first air pipe 7 and the air release port 63 by sliding and controlling the communication between the second air pipe 8 and the air release port 63 by sliding; an air release solenoid valve 9 is installed at the air release port 63.

[0049] Refer to Figures 6 to 13 As shown, when the valve core 62 is a one-way valve core, the one-way valve core can be a duckbill-shaped one-way valve core as shown in Figure 8 or an umbrella-shaped sealed one-way valve core as shown in Figure 10 and Figure 11 As shown. There are two one-way valve cores, which can be recorded here as the right valve core connected to the first air outlet pipe and the left valve core connected to the second air outlet pipe. At this time, a corresponding air release solenoid valve 9 needs to be installed at the air release port 63. That is, when the valve core 62 is a one-way valve core, the gas entering the first air outlet pipe will enter the position of the air release port 63 through the right one-way valve core. Correspondingly, the gas entering the second air outlet pipe will also enter the position of the air release port 63 through the left valve core. However, since the air release solenoid valve 9 at the position of the air release port 63 will be closed, the air release solenoid valve 9 can be opened to release the air in the first air outlet pipe or the second air outlet pipe.

[0050] In this embodiment, since the valve core 62 is a one-way valve core, that is, the gas can only be transported unidirectionally through the one-way valve core. Specifically, the gas from the first air outlet pipe enters the position of the air release port 63 through the right valve core, but does not enter the second air outlet pipe through the left valve core. Correspondingly, the gas from the second air outlet pipe enters the position of the air release port 63 through the left valve core, but does not enter the first air outlet pipe through the right valve core.

[0051] Specifically, when it is necessary to cancel the full drainage operation, that is, at this time, there is gas in the first air outlet pipe to drive the full drainage driving device. At this time, the gas in the first air outlet pipe enters the position of the air release port 63 through the right valve core. The air release solenoid valve 9 opens the air release port 63 to communicate with the outside, thereby discharging the gas in the first air outlet pipe and canceling the full drainage state; when it is necessary to cancel the half drainage operation, that is, at this time, there is gas in the second air outlet pipe to drive the half drainage driving device. At this time, the gas in the second air outlet pipe enters the position of the air release port 63 through the left valve core. The air release solenoid valve 9 opens the air release port 63 to communicate with the outside, thereby discharging the gas in the second air outlet pipe.

[0052] If the valve core 62 is a sliding valve core 62, it can be slid back and forth as needed, so that the first air outlet pipe is connected to the air release port 63 or the second air outlet pipe is connected to the air release port 63. At this time, the air release port 63 can always remain open, and at this time, the opening of the air release solenoid valve 9 can always be in an open state, or the use of the air release solenoid valve 9 can be discarded.

[0053] In this embodiment, the air release solenoid valve 9 is a normally open solenoid valve, that is, the opening is in an open state to communicate the air release port 63 with the outside in the non-powered state, and the opening is closed to seal the air release port 63 in the powered state; in practice, in order to reduce the power consumption, if the valve core 62 is a one-way valve core, the air release port 63 needs to be kept closed all the time and opened during use. At this time, the air release solenoid valve 9 can be selected as a normally closed solenoid valve; that is, its opening is closed in the power-off state, and only when it is powered on, its opening is opened to communicate the air release port 63 with the outside for air release treatment; if the valve core 62 is a sliding valve core 62, the air release port 63 can be kept open all the time, and at this time, the air release solenoid valve 9 can adopt a normally open solenoid valve.

[0054] A sound-absorbing cotton 11 is installed at the air outlet of the air release solenoid valve 9; refer to Figure 3 As shown, the sound-absorbing cotton 11 is used to reduce the noise generated during air release, thereby improving the user experience.

[0055] Air outlet connectors 10 are installed at the air outlet ends of the first air outlet pipe and the second air outlet pipe, and the air outlet connectors 10 are installed on the corresponding connecting parts; refer to Figures 1 to 5 As shown, by arranging air outlet structures at the air outlet ends of the first air outlet pipe and the second air outlet pipe, it can be connected to the full drainage driving device and the half drainage driving device adapted to it.

[0056] The present utility model also discloses a toilet drainage device, including a single air pump for realizing dual-flush control box as described in any one of the above, and the air circuit assembly includes a full air circuit for controlling the drainage device to achieve full drainage and a half air circuit for controlling the drainage device to achieve half drainage.

[0057] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
