As shown in <FIG>, the drainage mechanism <NUM> includes a valve body <NUM>, a return spring <NUM>, a piston <NUM>, and water-sealing rubber <NUM>. An installation plate <NUM> is connected below the water inlet in an outer wall of the valve body <NUM>, and the dual-outlet micro-pump <NUM> is fixed on the installation plate <NUM> to connect the drainage control water outlet <NUM> to the water inlet of the valve body <NUM>. The piston <NUM> divide the valve body <NUM> into an upper cavity and a lower cavity, the lower cavity is a drainage liquid cavity <NUM> communicated with a water inlet of the valve body <NUM>, and the return spring <NUM> is disposed in the upper cavity. The piston <NUM> is slidably arranged in the valve body <NUM>, and a lower end of the piston <NUM> extends out of the valve body <NUM> and is connected with the water-sealing rubber <NUM>. The water-sealing rubber <NUM> is sealed and adapted with the water outlet of the drainage base <NUM>. When the piston <NUM> moves downward, the water-sealing rubber <NUM> seals the drainage base <NUM>, and when the piston <NUM> moves upward, the water-sealing rubber <NUM> is opened to realize drainage. According to needs, a water supplement tube <NUM> or a water leakage tube <NUM> is further arranged at the water outlet of the drainage base <NUM>. In the present embodiment, the water supplement tube <NUM> and the water leakage tube <NUM> are connected at the same time, as shown in <FIG>.

The integrated drainage member of the present disclosure is in a dual control mode: as shown in <FIG>, when the valve body <NUM> is in a closed state, the water-sealing rubber <NUM> seals the water outlet of the drainage base <NUM>. When a mechanical control method is used, it is only necessary to pull the wire-controlled pull rope to drive the piston <NUM> to move upward, such that the water-sealing rubber <NUM> is separated from the drainage base <NUM>, then the water outlet of the drainage base <NUM> is opened, and the water in the water tank is flushed from the water outlet of the drainage base <NUM> into the toilet. When an electronic control method is used, the dual-outlet micro-pump <NUM> is started, part of the water in the water tank is pumped from the water inlet <NUM> of the dual-outlet micro-pump <NUM> through the filter screen <NUM>, and enters the drainage liquid cavity <NUM> from the drainage control water outlet <NUM>, and the other part of the water enters the washing tubing <NUM> of the toilet from the washing water outlet <NUM>. As shown in <FIG>, since the water enters the drainage liquid cavity <NUM>, the entire piston <NUM> slides upward under the action of the water pressure inside the valve body <NUM>, and the return spring <NUM> is compressed at the same time, thereby opening the water outlet of the drainage base <NUM>, and the water source in the water tank flows from the drainage base <NUM> into the toilet. As shown in <FIG>, the water from the washing water outlet <NUM> flows into the wall surface of the toilet cavity of the toilet through the washing tubing <NUM> to wash the toilet cavity.

The present embodiment provides an integrated water fitting assembly with a dual-outlet micro-pump, which has the functions of drainage, washing, and flushing. As shown in <FIG>, the present embodiment adds a flushing aid pump <NUM> and a flushing aid tube <NUM> on the basis of Embodiment I. The flushing aid pump <NUM> and the flushing aid tube <NUM> are connected through a flushing aid tubing <NUM>. The flushing aid tube <NUM> includes an inlet end connected with a pressurized water source end, and an outlet end inserted into the drainage base <NUM> and connected with the water outlet of the drainage base <NUM>.

As shown in <FIG>, the flushing aid pump <NUM> is disposed on a side of the drainage base <NUM>, and an installation bracket is arranged on the drainage base <NUM> for installing the flushing aid pump <NUM>. A filter screen <NUM> may be arranged at a position of the water inlet of the flushing aid pump <NUM>. In other embodiments, the flushing aid pump <NUM> may also be integrated in the housing <NUM>, and the water outlet of the flushing aid pump <NUM> extends out of the housing <NUM>.

As shown in <FIG>, a water-passing cavity is arranged inside the flushing aid pump <NUM>, an impeller of the flushing aid pump <NUM> is located in the water-passing cavity, and a water inlet and a water outlet of the flushing aid pump <NUM> are both communicated with the water-passing cavity of the flushing aid pump.

As shown in <FIG>, the flushing aid tubing <NUM> is set in a U-shape, and the flushing aid tubing <NUM> includes one end connected with the flushing aid pump <NUM>, and the other end connected with the flushing aid tube <NUM>. In the present embodiment, a venturi tube is selected as the flushing aid tube <NUM>, and the venturi tube has a gradually reduced diameter at the outlet end, which can better increase the flow rate of fluid and achieve a better flushing aid effect. Several venturi tubes can be provided (two venturi tubes are provided in <FIG>). If more than one venturi tubes are provided, several branch tubes can be connected at the end of the flushing aid tubing <NUM> through an adapter, and each branch tube can be connected with the venturi tube respectively. The venturi tube can be integrally formed or assembled from several sections of tube body. In the form of assembly, the venturi tube can be assembled with structures of different materials according to needs, and can also be arranged in different directions according to different needs. The venturi tube can be made into U-shaped or L-shaped according to the needs, such that the water flow at the outlet end of the venturi tube is sprayed in different directions.

An anti-siphon hole <NUM> is formed in an upper part of the flushing aid tubing <NUM>, and the anti-siphon hole <NUM> is higher than a working water level set in the water cavity, which can prevent siphoning.

When the smart toilet starts flushing, a main control unit independently drives the flushing aid pump <NUM> to work according to the needs. The flushing aid pump <NUM> pumps the water in the water cavity of the toilet into the flushing aid tube <NUM>, the flow rate of the flushing aid water at the inlet end of the flushing aid tube <NUM> is a, and water is sprayed out from the outlet end of the flushing aid tube <NUM> through a small cross-sectional tube diameter. The flow rate of the flushing water is increased to a'. Due to the increased flow rate at the outlet end, the flow rate of the water discharged from the drainage base <NUM> is also increased, such that the flow rate of the water is increased from b to b', thereby effectively improving the ability of flushing the toilet cavity.

As shown in <FIG>, the present embodiment provides an integrated water fitting assembly with a dual-outlet micro-pump, which has the functions of drainage, washing, and flushing. The present embodiment adds a flushing aid tube on the basis of Embodiment I. An inlet end of the flushing aid tube <NUM> is connected with the inlet valve <NUM> of the toilet through a water supply tube <NUM>, and a solenoid valve <NUM> for controlling on-off of the water flow in the water supply tube <NUM> is arranged on the water supply tube <NUM>.

When the smart toilet starts flushing, a main control unit independently drives the solenoid valve <NUM> to work according to the needs, the water in the inlet valve <NUM> enters the flushing aid tube <NUM> through the water supply tube <NUM>, and the diameter of the outlet end of the flushing aid tube <NUM> is gradually reduced. Since the diameter is reduced, the flow rate of the fluid is increased when the restricted flow passes through the reduced flow cross-section. The flushing aid water flow of the flushing aid tube <NUM> is ejected from a nozzle to increase the flow rate of the water in the drainage base <NUM>, which further drives the flow rate of the water in the flushing tubing of the smart toilet, thereby increasing the jet force for flushing the toilet cavity.

As shown in <FIG> and <FIG>, the present embodiment provides an integrated water fitting assembly, including: a housing <NUM>, a drainage mechanism <NUM>, a dual-head flow distribution assembly <NUM>, a micro-pump <NUM>, and a drainage base <NUM>.

The water-sealing rubber <NUM> is sealed and adapted with the water outlet of the drainage base <NUM>. When the piston <NUM> moves downward, the water-sealing rubber <NUM> seals the drainage base <NUM>, and when the piston <NUM> moves upward, the water-sealing rubber <NUM> is opened to realize drainage. According to needs, a water supplement tube <NUM> or a water leakage tube <NUM> is further arranged at the water outlet of the drainage base <NUM>. In the present embodiment, the water supplement tube <NUM> and the water leakage tube <NUM> are connected at the same time, as shown in <FIG>. The water supplement tube <NUM> is connected with the inlet valve <NUM> of the smart toilet, such that the water supplement function of the toilet can be realized.

The integrated drainage member of the present disclosure is in a dual control mode: as shown in <FIG>, when the valve body <NUM> is in a closed state, the water-sealing rubber <NUM> seals the water outlet of the drainage base <NUM>. When a mechanical control method is used, it is only necessary to pull the wire-controlled pull rope to drive the piston <NUM> to move upward, such that the water-sealing rubber <NUM> is separated from the drainage base <NUM>. Then, the water outlet of the drainage base <NUM> is opened and the water in the water tank is flushed from the water outlet of the drainage base <NUM> into the toilet. When an electronic control method is used, the dual-outlet micro-pump <NUM> is started, part of the water in the water tank is pumped by the micro-pump <NUM>, enters the drainage liquid cavity <NUM> from the drainage control water outlet <NUM>, and the other part of the water enters the washing tubing <NUM> of the toilet from the washing water outlet <NUM>. As shown in <FIG>, since the water enters the drainage liquid cavity <NUM>, the entire piston <NUM> slides upward under the action of the water pressure inside the valve body <NUM>, and the return spring <NUM> is compressed at the same time, thereby opening the water outlet of the drainage base <NUM>, and the water source in the water tank flows from the drainage base <NUM> into the toilet. As shown in <FIG>, the water from the washing water outlet <NUM> flows into the wall surface of the toilet cavity of the toilet through the washing tubing <NUM> to wash the toilet cavity.

As shown in <FIG>, the present embodiment provides an integrated water fitting assembly. The difference between the present embodiment and Embodiment IV is: the dual-head flow distribution assembly <NUM> in the present embodiment includes a distribution body <NUM> with a hollow cavity and a delay mechanism <NUM> located inside the distribution body <NUM>. An installation plate <NUM> is connected below the water inlet in an outer wall of the valve body <NUM> of the drainage mechanism <NUM> and the dual-head flow distribution assembly <NUM> is fixed on the installation plate <NUM> to connect the drainage control water outlet <NUM> to the water inlet of the valve body <NUM>.

As shown in <FIG>, the delay mechanism includes a water distribution piston <NUM>, a delay spring <NUM>, and an adjusting member. The adjusting member includes an adjusting knob <NUM> and an adjusting plate <NUM> fixedly connected with the adjusting knob. The adjusting plate <NUM> is located inside the distribution body <NUM>, and the adjusting knob <NUM> extends out of the distribution body <NUM>. The adjusting member is disposed on the distribution body <NUM> movably up and down. For example, in the present embodiment, screw transmission connection is used: a threaded hole is formed in an upper part of the distribution body <NUM>, an external thread is formed in an outer wall of the adjusting knob <NUM>, and the adjusting knob <NUM> is inserted into the threaded hole to be connected with the distribution body <NUM> by screw transmission. Other up and down movement methods can also be used, such as controlling the up and down movement of the adjusting plate through a motor push rod.

The water distribution piston <NUM> separates the hollow cavity of the distribution body <NUM> into an upper cavity and a lower cavity, the delay spring <NUM> is located in the upper cavity, an upper end of the delay spring <NUM> abuts against the adjusting plate <NUM>, and a lower end of the delay spring <NUM> abuts against the water distribution piston <NUM>.

As shown in <FIG>, after a water pressure acts on the water distribution piston <NUM> to compress the delay spring <NUM>, the washing water outlet <NUM> and the drainage control water outlet <NUM> are both communicated with the flow water inlet <NUM>. In the present embodiment, toilet washing is controlled first and then drainage is realized. By exchanging the positions of the washing water outlet <NUM> and the drainage control water outlet <NUM>, the toilet drainage can also be controlled first, and then washing is realized. As shown in <FIG>, by moving the adjusting knob <NUM> up and down, a compression length of the delay spring <NUM> can be adjusted, thereby adjusting the elastic force of the delay spring <NUM> to achieve different delay requirements.

As shown in <FIG> and <FIG>, in other implementations, the delay mechanism may only include the water distribution piston <NUM> and the delay spring <NUM>. The upper end of the delay spring <NUM> abuts against the upper wall of the distribution body <NUM>, and the lower end of the delay spring <NUM> abuts against the water distribution piston <NUM>. By selecting a suitable delay spring, the demand for the delay of the upper outlet can be realized.

As shown in <FIG>, in order to prevent "air trapping" caused by excessive air in the distribution body, a first pressure relief hole <NUM> is formed in an upper part of the distribution body <NUM>, and a second pressure relief hole <NUM> is formed in the water distribution piston <NUM>, such that the air is discharged to the outside of the distribution body in time.

By reasonably setting a volume flow rate of the inner cavity of the dual-head flow distribution assembly, a diameter of the water inlet, a diameter of the washing water outlet, and a diameter of the drainage control water outlet, the water outlet of the micro-pump can have a head of <NUM>-<NUM> and a flow rate of <NUM>-<NUM>/min, the drainage control water outlet can have a head of <NUM>-<NUM> and a flow rate of <NUM>-<NUM>/min, and the washing water outlet can have a head of <NUM>-<NUM> and a flow rate of <NUM>-<NUM>/min, so as to satisfy the needs for washing and drainage of the smart toilet.

The present embodiment provides an integrated water fitting assembly, which has the functions of drainage, washing, and flushing aid. The present embodiment adds a flushing aid pump <NUM> and a flushing aid tube <NUM> on the basis of Embodiment IV or Embodiment V. The connection and use principle of the flushing aid pump <NUM> and the flushing aid tube <NUM> are the same as those in Embodiment II.
