Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined to clearly and completely describe the technical solutions of the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
Referring to fig. 1, the utility model provides a foam soap dispenser, which comprises a faucet 1, wherein the end of the faucet 1 is provided with a liquid outlet joint 11, and the faucet 1 is further provided with a soap dispensing sensing window 12; the soap feeding device 2 comprises a liquid inlet pipe 21, an air inlet pipe 22, a two-way pump 23, a soap liquid bottle 24 and an air pump 25; one end of the liquid inlet pipe 21 is communicated with the liquid outlet joint 11, and the other end is communicated with the soap liquid bottle 24 through the two-way pump 23; one end of the air inlet pipe 22 is connected with the air pump 25, and the other end of the air inlet pipe is communicated with the liquid outlet joint 11; a controller 3 connected to the soap supply sensing window 12, the bidirectional pump 23 and the air pump 2, respectively5, connection; the main controller 3 is used for controlling the bidirectional pump 23 and the air pump 25 to be separated for a preset time T when receiving the signal of the soap feeding induction window 121The opening is carried out successively, so that the soap liquid and the air are mixed at the liquid outlet joint 11 simultaneously; the main controller 3 is further configured to control the air pump 25 to stop working after the use is finished, and simultaneously control the two-way pump 23 to reversely rotate to pump the soap liquid into the liquid inlet pipe 21.
When in use, the hand is placed at the soap-feeding induction window 12, the main controller 3 receives the liquid-discharging signal and then controls the soap-feeding device 2 to start working, the two-way pump 23 and the air pump 25 are arranged at preset time intervals T1The soap liquid and the air are respectively liquid and gas, so that the density and the state are greatly different, and the flow rate of the soap liquid is less than the air flow rate when the pump body pumps. Therefore, the bidirectional pump 23 starts to operate before the air pump 25, so that the soap liquid and the air reach the liquid outlet joint 11 simultaneously to be mixed, the mixing is more complete, and the foaming is more uniform.
Preferably, the predetermined time T1Is 0.3-1 second, and the preset time T is set according to different soap liquid conditions in the using process1. The foam is not completely sucked due to too short pumping time, the motor is not controlled easily due to too fast switching, and the service life of the motor is shortened; the pumping-back time is too long, so that the use effect is influenced, and the practicability is reduced.
After the liquid outlet signal disappears, the residual unused foam in the faucet 1 can be pumped back by controlling the bidirectional pump 23 through the main controller 3 to enable the foam to flow back, the bidirectional pump 23 stops working after a certain time, the foam flows back into the liquid inlet pipe 21, and the foam can be extruded for use next time. The foam is the mixture of the soap liquid and the air, even the foam flows back to the soap liquid bottle 24 along the liquid inlet pipe 31, the soap liquid in the bottle can not be polluted, the soap liquid waste is reduced, and the cleaning performance can not be influenced.
In one embodiment, the main controller 3 further controls the two-way pump 23 to reversely pump the soap liquid into the liquid inlet pipe 21 for a pumping time T1And pumping the foam back to the liquid inlet pipe 21 until the foam is pumped out again for use next time.
In another embodiment, the main controller 3 further controls the two-way pump 23 to reversely pump the soap liquid into the liquid inlet pipe 21 for a pumping time T1+0.1～T1+0.5, considering that the foam stays in the liquid inlet pipe 21 and also slides down continuously under the action of gravity, the pumping-back time is increased by 0.1-0.5 second, so that the foam can directly flow back to the soap liquid bottle 24, the soap liquid bottle is convenient to store and use, and the foam and the soap liquid are both soap liquid in nature and cannot cause soap liquid pollution.
The whole liquid outlet process is transmitted to the main controller through the soap feeding induction window to receive signals, and then the main controller controls all elements to complete the liquid outlet process without additional operation or direct contact with a foam soap feeder, so that the soap dispenser is more convenient and sanitary to use; and by setting the interval predetermined time T to the main controller1The liquid soap and the air can reach the liquid outlet joint simultaneously to be mixed and foamed, so that the foam is more uniform, and the use feeling of a user is improved.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
