Referring to fig. 2, in the conventional foam shield system, the liquid pump 107 is small due to assembly requirements, and the liquid pump 107 needs to be started first to suck foaming liquid into the pump cavity, so that the conventional foam shield system can work well after the foaming liquid is in the pump cavity. However, when the negative pressure is 0.05MPa, the liquid pump 107 cannot discharge air, and the selection of the type of the liquid pump 107 is particularly important, and the requirement of the whole system on the liquid pump 107 is high. In view of this, in the present application, the liquid pump mechanism pumps the foaming liquid into the oscillation cavity 113 through the liquid suction pipeline; one of the liquid suction pipelines and the liquid suction pipe 104 are the same pipeline and are used for conveying the foaming liquid to the oscillation cavity 113 in a pump mode.

Water is input into the oscillation cavity 113 through the water conveying pipeline 105; the water conveying pipeline 105 is arranged at the top of the upper shell 101 and is communicated with the oscillation cavity 113, and the water conveying pipeline 105 adopts an external water source; the pressure of the external water source is 0.4Mpa, so that after the foaming liquid is pumped by the liquid pump 107, the foaming liquid is subjected to impact mixing to form a vortex mixing liquid of the water and the foaming liquid.
Referring to fig. 3 and 4 together, in the existing foam shield system, because the liquid pump 107 is relatively small, the pump needs to be started first, and the foam shield system can work well after liquid is sucked into the pump cavity and the cavity has liquid therein (when the negative pressure is 0.05Mpa, the liquid pump 107 cannot discharge air at present), so that the gas backflow occupies the pump cavity of the liquid pump 107, and the one-way flow check valve 112 is adopted to stop the gas backflow in the present application.
Specifically, the liquid pump mechanism includes a liquid pump 107 disposed inside the housing; the liquid pump 107 is started by supplying 5v voltage through the power supply line 109, and the liquid suction end and the pump liquid end of the liquid pump 107 are hermetically connected with the liquid suction pipeline. By sealing the connection, air is prevented from entering the pump chamber of the liquid pump 107, and the response of the liquid pump 107 in switching to deliver foaming liquid is more sensitive.
The pipette path in the embodiment of the present application includes: an adaptor 110 having two passages; the adaptor 110 is pushed into the housing for limiting, and the adaptor 110 is limited and mounted in the upper housing 101 in an interference connection mode. The adaptor 110 has a first passage for sucking up foaming liquid and a second passage for pumping foaming liquid into the one-way valve 112, and liquid pump seals 108 are fitted between the first passage and the liquid suction end of the liquid pump 107 and between the second passage and the pump liquid end of the liquid pump 107, thereby achieving sealing between the liquid pump 107 and the adaptor 110.
When the first passage of adapter member 110 is sealingly connected to the intake end of liquid pump 107 and the second passage of adapter member 110 is sealingly connected to the pump end of liquid pump 107, the end of the second passage remote from liquid pump 107 communicates with oscillation chamber 113 through one-way valve 112. A one-way valve seal 111 is fitted between the one-way valve 112 and the second passage to ensure a seal between the one-way valve 112 and the adaptor piece 110.
And in order to increase the flow rate of the foaming liquid pumped into the oscillation cavity, a first narrow throat reducing pipe 114 is arranged at the joint of the one-way valve 112 and the oscillation cavity 113, so that the foaming liquid pumped by the liquid pump 107 rapidly flows into the oscillation cavity 113 through the first narrow throat reducing pipe of the one-way valve 112, and is mixed with the entering water in a vortex mode.
A second narrow throat reducing diameter 116 is arranged between the oscillating cavities 113 of the water conveying pipeline 105, and water with pressure outside enters the oscillating cavities 113 through the second narrow throat reducing diameter 116 of the water conveying pipeline 105 in a state of rapid increase of flow rate by the arrangement of the second narrow throat reducing diameter 116, so that the water and the foaming liquid are mixed rapidly.
The foaming liquid and the water meet inside the oscillating chamber 113 to form a vortex. The problem of difficulty in mixing liquid is solved by collecting the liquid to the oscillation cavity 113 through two different pipelines. In addition, in the embodiment of the present application, in order to better mix the water and the foaming liquid to form a vortex, a tapered swirling protrusion 115 is disposed at the bottom of the oscillation cavity 113, so that the water and the foaming liquid form a vortex after rapidly entering the oscillation cavity 113.
As can be seen from the above description, the foaming liquid is filled in the liquid reservoir and is connected to the liquid suction pipe 104 through the silicone tube; the pressurized water is rapidly fed into the oscillation cavity 113 through the second narrow throat diameter-changing 116, and the liquid pump 107 synchronously pumps the foaming liquid into the oscillation cavity 113 in a rapid state through the adapter 110. Check valve 112 prevents backflow of air from occupying the pump chamber of liquid pump 107 after liquid pump 107 is deactivated. The liquid outlet direction of the one-way valve 112 and the water outlet direction of the water conveying pipeline 105 are distributed at a right angle, so that external water with pressure impacts foaming liquid at a variable speed, and a vortex is easily formed under the structural action of the rotational flow protrusion 115 of the oscillation cavity 113, and a better mixing effect is achieved. Of course, it should be understood that the liquid outlet direction of the check valve 112 and the water outlet direction of the water conveying pipeline 105 may also adopt an included angle equal to 90 ° or smaller than 90 °, so as to realize the vortex flow in the oscillation cavity 113 in the self-flowing state of the water impact foaming liquid.
The bottom of the oscillation cavity 113 is connected with an infusion tube 106, and the infusion tube 106 is used for conveying primary mixed liquid formed by mixing water and foaming liquid to the foaming nozzle assembly 200 to form foam.
Referring to fig. 5, fig. 5 is a schematic diagram illustrating an exploded structure of a foaming nozzle assembly provided in an embodiment of the present application. The foaming nozzle assembly 200 replaces the air inlet function of the air pump by utilizing the structure of the foaming nozzle assembly, fully utilizes the phenomenon of two venturi, realizes natural air suction, achieves the effect of adopting one liquid pump 107, and can meet the same foaming effect with other foam shield systems.
Specifically, the foaming nozzle assembly 200 includes: a first nozzle 203, a second nozzle 205 and a foaming net 208 which are connected from top to bottom in sequence. A sealing cover 202 is hermetically connected above the first nozzle 203, the sealing cover 202 is used for sealing the top of the first nozzle 203, a reducer 201 is arranged on one side of the first nozzle 203, and a silicone tube is connected between the infusion tube 106 and the reducer 201, so that a primary mixed liquid which forms vortex mixing in the oscillation cavity 113 flows into the first nozzle 203, and the primary mixed liquid is continuously mixed and rotated and the flow rate is increased under the action of the first nozzle 203.
Water liquid mixing assembly 100 and foaming shower nozzle subassembly 200 adopt split type setting, according to the assembly demand, select for use the silicone tube of different length to connect, increase nimble assembly performance. In addition, the first nozzle 203, the second nozzle 205 and the foaming net 208 are connected in a snap-fit manner by using buckles. The first nozzle 203 is connected to the inside of the second nozzle 205 through a second clamping structure 206; specifically, second joint structure 206 includes, relatively or along the second buckle that first nozzle 203 circumference set up, set up the second draw-in groove with second buckle one-to-one on second nozzle 205, when first nozzle 203 moves towards the inside of second nozzle 205, the inside of second buckle one-to-one joint at the second draw-in groove to make the fixed assembly of first nozzle 203 in the inside of second nozzle 205, it is more convenient to guarantee the dismouting simultaneously.
The lower part of the second nozzle 205 is provided with a reducing nozzle 207, the foaming net 208 is clamped and fixed on the reducing nozzle 207 through a third clamping structure 209, and the foaming net 208 is made of a steel wire mesh and steel wire mesh fixing pieces. Specifically, the third clamping structure 209 includes, relatively or along the third buckle that reducing spout 207 circumference set up, set up the third draw-in groove with third buckle one-to-one on the wire net mounting, when reducing spout 207 moved to the inside of wire net mounting, the inside at the third draw-in groove of third buckle one-to-one correspondence joint to make foaming net 208 fixed assembly in the bottom of second nozzle 205, make reducing spout 207 spun high-speed liquid impact the wire net and form the foam. Adopt the joint structure to connect, reduce connection process, it is more convenient to assemble, is convenient for later stage change maintenance.
Referring to fig. 6, when the liquid is made to increase the rotational flow rate inside the first nozzle 203 and generate the primary venturi suction effect, an L-shaped water channel 204 communicated with the reducing pipe is provided inside the first nozzle 203, and the diameter of the water outlet 210 of the L-shaped water channel 204 is smaller than the diameter of the water inlet of the L-shaped water channel. By using the difference in diameter between the water inlet and the water outlet of the L-shaped water channel, the primary mixed liquid is caused to flow through the L-shaped water channel at an increased rotational flow rate and enter the second nozzle 205 at a rapidly increased flow rate.
As can be seen from the above description, the first-stage mixed liquid has a certain self-rotation force after flowing into the L-shaped water channel 204; the primary mixed liquid with the rotary flow rate forms a water column with an olive-shaped cavity after flowing out of the water outlet 210 after passing through the L-shaped water channel 204, so that the whole primary mixed liquid is slightly thick and does not lose the flow rate, air is absorbed for the first time, when the primary mixed liquid flows to the second nozzle 205 through the water outlet 210 of the first nozzle 203, the rotary flow rate of the primary mixed liquid is easily increased by using the mode that the caliber of the water outlet 210 is reduced, and the water column with the olive-shaped cavity generates a primary venturi suction effect.
Furthermore, the diameter of the water outlet 210 of the L-shaped water channel 204 is reduced, so that the flow speed of the primary mixed liquid is increased when the primary mixed liquid flows out of the L-shaped water channel 204, and an olive-shaped cavity is formed under the action of a rotating effect, so that air is absorbed, and the primary Venturi suction effect is facilitated.
After the primary mixed liquid flows out through the first nozzle 203, a secondary mixed liquid with increased flow rate and sufficient gas content is formed, and the secondary mixed liquid enters the second nozzle 205 in a self-flowing state with increased flow rate. The secondary mixed liquid formed by the first nozzle 203 flows through the second nozzle 205 and then impinges on the foaming net 208, and a secondary venturi suction effect is generated to form foam. Specifically, the primary mixed liquid and the secondary mixed liquid are both a mixture of water and a foaming liquid, and form foam after passing through the water liquid mixing assembly and the foaming head assembly, wherein the mixing and suction forms are different, so that the water liquid mixed liquid is defined as the primary mixed liquid, the liquid sucked through the first nozzle 203 to cause primary foaming is defined as the secondary mixed liquid, and finally the secondary mixed liquid is formed into foam after being impacted on the foaming net 208 through the second nozzle 205.
Specifically, a reducing nozzle 207 facing the foaming net 208 is arranged at the bottom of the second nozzle 205, and the diameter of the reducing nozzle 207 is smaller than the diameter of the second nozzle 205 and the diameter of the foaming net 208. When the high-flow-rate secondary mixed liquid flows through the reducing nozzle 207, a secondary Venturi suction effect is triggered, a large amount of gas is brought in, and finally, the gas collides on the foaming net 208 to form foam.
In the invention, under the condition that the conditions of flow speed, pressure and the like in the oscillation cavity 113 are met, liquid can form a vortex in the oscillation cavity 113 through the structure of the oscillation cavity 113, and the problem of difficulty in liquid mixing is solved by using the vortex of the oscillation cavity 113 to mix liquid. Meanwhile, the self structure of the foaming nozzle assembly 200 is utilized to replace the air inlet function of the air pump, the two venturi phenomena are fully utilized, natural air suction is realized, and the same foaming effect as other foam shield systems can be met by adopting one liquid pump 107.
In addition, the invention also provides an intelligent closestool which comprises an intelligent closestool body, wherein the intelligent closestool is provided with the built-in foam generating device of the first aspect. Therefore, the intelligent closestool body reduces the requirement for selecting the type of the liquid pump and simplifies the assembly process.
The intelligent closestool also comprises a control system, and the control system is electrically connected with the liquid pump through signals. When the foam generating device is used, a button does not need to be pressed in advance, and the control system is connected with the liquid pump to automatically generate foam and stop generating foam.
The controller system is a master device for controlling the starting, speed regulation, braking and reversing of the motor by changing the wiring of a main circuit or a control circuit and changing the resistance value in the circuit according to a preset sequence. The system consists of a program counter, an instruction register, an instruction decoder, a time sequence generator and an operation controller, and is a decision mechanism for issuing commands, namely, the decision mechanism is used for coordinating and commanding the operation of the whole computer system.
