Detailed Description
the technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
A foam generating apparatus of this embodiment, as shown in fig. 1, includes a case 1, a water inlet pipe 2, a first valve 3 and a foam guiding pipe 4, wherein a middle partition plate 101 is disposed in the case 1, the middle partition plate 101 divides the inside of the case 1 into a foam generating chamber 102 and a foaming agent storage chamber 103, a foaming agent outflow hole 104 is disposed at the bottom of the middle partition plate 101, the bottom of the foam generating chamber 102 is communicated with the foaming agent storage chamber 103 through the foaming agent outflow hole 104, a water spray opening 105 is disposed at the top surface of the foam generating chamber 102, a pressure opening 106 is disposed at the top surface of the foaming agent storage chamber 103, one end of the water inlet pipe 2 is connected to the water spray opening 105 and the pressure opening 106, the other end of the water inlet pipe 2 is connected to a tap water pipe 7 through the first valve 3, one end of the foam guiding pipe 4 is connected to the lower end of the foam generating chamber 102, the foaming agent storage chamber 103 stores a foaming agent 107 therein.
When in use, the first valve 3 is opened, tap water enters the foam generating chamber 102 and the foaming agent storage chamber 103 from the water inlet pipe 2, the foaming agent 107 in the foaming agent storage chamber 103 flows to the bottom of the foam generating chamber 102 from the foaming agent outflow hole 104, when tap water entering the foam generating chamber 102 from the water outlet 105 hits the foaming agent 107 at the bottom of the foam generating chamber 102, a large amount of foam is rapidly generated, and then the air pressure at the upper part of the foam generating chamber 102 is increased due to the continuous increase of foam in the foam generating chamber 102, so that the foam flows out from the foam guide pipe, and only the foam guide pipe 4 is connected to the urinal 6; further, the foam that has not yet flowed out of the foam generating chamber 102 is stored in the foam generating chamber 102, and the foam can be quickly supplied when the next foam generation is required.
The tap water is led to the foaming agent storage chamber 103, so that the situation that the foaming agent 107 cannot flow into the foam generating chamber 102 from the pores of the foaming agent 107 due to negative pressure formed in the upper space in the foaming agent storage chamber 103 can be prevented, the foaming effect of the foaming agent 107 cannot be influenced by the dilution of the tap water on the foaming agent 107, and the foaming effect can still be achieved when the tap water impacts the foaming agent in the foam generating chamber 102.
The top surface of the foaming agent storage chamber 103 is also provided with a filling port 108 and a sealing cover 109, and the sealing cover 109 is hermetically covered on the filling port 108 through threads; a one-way valve 110 is arranged between the water spraying opening 105 and the water inlet pipeline 2, and a high-pressure nozzle 111 is arranged at the water spraying opening 105.
Since the foaming agent 107 is a consumable, after the foaming agent is used for a period of time, the foaming agent 107 needs to be supplemented into the foaming agent storage chamber 103, and the foaming agent 107 can be conveniently added into the foaming agent storage chamber 103 by arranging the filling port 108; the sealing cover 109 can seal the filling opening 108 to prevent dust from entering, and can also play a role of sealing, a one-way valve 110 is arranged between the water spraying opening 105 and the water inlet pipeline 2 to prevent air from entering the foaming agent storage chamber 103 from the foaming agent generation chamber 102, when the first valve 3 is closed, the upper space of the foaming agent storage chamber 103 can form a negative pressure closed space, so that the foaming agent 107 can not flow into the foaming agent generation chamber 102 from the foaming agent outflow hole 104 under the action of atmospheric pressure, when the first valve 3 is opened, a small amount of tap water and air flow into the foaming agent storage chamber 103 to increase the air pressure of the upper space in the foaming agent storage chamber 103, so that the foaming agent 107 can flow out from the foaming agent outflow hole 104, namely, only when the first valve 3 is opened, the foaming agent 107 can flow into the foaming agent generation chamber 102 to play a role of foam random control, the use of the foaming agent 107 can also be saved.
The high pressure nozzle 111 provided at the water jet 105 can make tap water strongly impact on the foaming agent 107 at the bottom of the foam generating chamber 102, and can generate a large amount of foam instantaneously to shorten the foaming time.
The other end of the bubble guide pipe 4 is connected with the water outlet of the urinal 6, and a bubbler 41 is arranged at one end, close to the urinal 6, in the bubble guide pipe 4.
Because the pressure of the foam is unstable when the foam flows out of the foam guide pipe 4, the foam is unstable when the foam flows out, and the phenomenon of explosion or sputtering can occur, so that the bubbler 41 can play a role in stabilizing, the pressure of the foam when the foam flows out is more stable, and the foam is uniformly discharged; in addition, since the foam is generated when tap water impacts the foaming agent 107, the foam is not uniform in size and is relatively coarse, and surrounding foam is easily splashed around when the large foam is broken; the bubbler 41 can further refine the foam, so that the flowing foam is finer and smoother, the impact force of the fine foam is smaller when the fine foam is crushed, the problem of sputtering can not occur when the fine foam is crushed, and the using effect is better.
The case 1 is made of transparent plastic.
The use of clear plastic allows the remaining amount of foamable composition 107 to be easily observed to facilitate the timely addition of foamable composition 107 to foamable composition storage chamber 103.
The first valve 3 is an infrared induction flushing valve, and the first valve 3 is used for controlling the communication and the stop of the water inlet pipeline 2.
The infrared induction flushing valve can automatically make bubbles when a human body approaches the urinal 6, and the use is more convenient.
The outside parcel of box 1 has soundproof cotton 5, soundproof cotton 5 is in filler 108 department is equipped with and dodges the position.
Because the foam is formed by spraying tap water from the water spray opening 105 in the foam generating chamber 102 to impact the foaming agent 107 at the bottom of the foam generating chamber 102, the noise is higher in the early stage of the foaming process, and the soundproof cotton 5 can effectively reduce the outward diffusion of the noise and play a role of silencing; the provision of a relief location at the fill port 108 facilitates the addition of the foaming agent 107 from the fill port 108.
The diameter of the foaming agent outflow hole 104 is 0.5-3 cm.
Because the foaming agent 107 has certain viscosity, when the diameter of the foaming agent outflow hole 104 is less than 0.5cm, the foaming agent 107 is not easy to flow from the foaming agent storage chamber 103 to the foam generation chamber 102, which easily causes the problem of too small foaming amount; when the diameter of the foam discharging hole is larger than 3cm, a large amount of the foaming agent 107 flows into the foam generating chamber 102 due to an excessively large hole diameter, and an excessive amount of the foaming agent 107 flows into the foam generating chamber 102, which causes an excessive amount of foam generation, resulting in waste.
As shown in fig. 2, the urinal 6 using the foam generating device is provided with a water outlet for discharging foam or clean water; the water outlet is simultaneously connected with the bubble guide pipe 4 and the tap water pipe 7, a second valve 61 is arranged between the tap water pipe 7 and the water outlet, and the second valve 61 is an infrared induction flushing valve.
The provision of the second valve 61 advantageously controls flushing of the urinal 6: when a human body approaches the urinal 6, tap water is communicated with the first valve 3 to make bubbles, foam flows to the bottom of the urinal 6 through the bubble guide pipe 4 under the action of atmospheric pressure, and the bubble making time can be preset to avoid waste caused by excessive bubble making; when the human body leaves the urinal 6 after defecation, the second valve 61 is connected with tap water, and the tap water is used for flushing the foam; if the foam is directly used for flushing, the foam cannot be flushed away, so that a large amount of foam remains in the urinal 6, and the foam with bacteria or excrement is splashed out of the urinal 6 when the foam collides with the foam.
The water outlets 62 are multiple and are horizontally and uniformly arranged along the inner side of the urinal 6.
The even arrangement of the water outlets 62 can make the foam flow evenly to the bottom of the urinal 6, so that the foam can be evenly covered on the bottom of the urinal 6, and the phenomenon that the foam is not covered on part of the positions and cannot play a role in buffering and preventing splashing is prevented.
The diameter of the water outlet 62 is 2-5 cm.
Because the mobility of the foam is poor, when the diameter of the water outlet 62 is smaller than 2cm, the foam is difficult to flow into the urinal 6, and the bottom of the whole urinal 6 can be covered for a long time, so that the use is inconvenient; when the diameter of the water outlet 62 is larger than 5cm, the water outlet pressure of the water outlet 62 is too low to flush the foam in the urinal 6.
The technical principle of the present invention is described above with reference to specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without any inventive effort, which would fall within the scope of the present invention.
