Description

Technical Field

[0001] The invention relates to the technical field of foaming devices, in particular to an automatic quantitative mixing foaming device without electricity and a working method thereof. Background Art

[0002] With the development of science and technology, more and more new technologies are coming into the public eye, bringing earth-shaking changes to human production and life. Despite this, basic science, as the research basis for current new technologies and new sciences, still has great potential for exploration. The Venturi effect, as one of the basic sciences, is widely used in production and life. However, existing Venturi mixers have a series of problems such as insufficient two-phase mixing and uneven mixing without foaming.

[0003] With the continuous development of society, people's living standards are constantly improving. In modern families, whether it is the use of dishwashing liquid, hand soap, washing machine laundry detergent, or bath gel and shampoo, the use process is through manual pressing or electric liquid dispensing. Especially manual, it is difficult to grasp the amount of liquid to be judged by the user's subjective experience. There is a large error in the added dosage, resulting in unnecessary waste and affecting the washing effect. In order to increase the cleaning power, the liquid is rubbed by hand to produce foam, which increases the cleaning time and the foaming is uneven, and it is not mixed with water. Such a high concentration of cleaning liquid dripping on the hands or on the clothes to be washed will cause damage to the skin or the cleaned items, and may even easily lead to incomplete cleaning and excessive residual cleaning liquid, which will affect human health.

[0004] Therefore, an automatic quantitative foaming device without electricity and a working method thereof are proposed. Summary of the Invention

[0007] Preferably, the water outlet conversion assembly includes a water outlet pipe connected to the bottom of the circular placement seat, the top of one side of the water outlet pipe is connected to a docking elbow, the docking elbow is connected to the circular base at one end away from the water outlet pipe, and a water outlet for use with the docking elbow is provided on the right side of the inner cavity of the circular base, and manual valves are provided on the water outlet pipe and the docking elbow, and the valve stems of the two groups of manual valves are fixed to each other, and the right end of the valve stem of one group of manual valves passes through the shell and is fixedly connected to a knob, and the left side of the knob is fitted on the shell.

[0008] Preferably, the auxiliary liquid outlet component includes a circular cover fixedly connected to the back side of the bottom of the inner cavity of the liquid storage cylinder, the bottom of the liquid storage cylinder is fixedly connected to a cylinder, the bottom of the inner cavity of the circular base is provided with a circular groove for use with the cylinder, and the top of the second liquid outlet hole is connected to the circular groove, a Venturi tube for use with the water outlet is provided in the cylinder, a cross valve is vertically provided on the circular cover, a drainage hole for use with the cross valve is provided on the Venturi tube, and a placement hole for use with the cross valve is provided on the back side of the left side of the circular base.

[0009] Preferably, a filter screen is placed on the circular placement seat, an elastic washer used in conjunction with the filter screen is clamped in the fixing ring, and the bottom of the elastic washer is clamped in the circular placement seat, and the top of the elastic washer is fitted on the docking nut.

[0010] Preferably, the valve plates of the two groups of manual valves are respectively arranged horizontally and vertically.

[0011] Preferably, a rubber sealing cover is clamped on the liquid storage cylinder, and any one of detergent, hand soap, laundry detergent, etc. can be added into the liquid storage cylinder.

[0012] Preferably, a docking ring that can be docked with the water inlet pipe of the washing machine is fixedly connected to the right side of the bottom of the shell, and the first liquid outlet is located in the docking ring.

[0013] A method for operating a non-electrical automatic quantitative mixing and foaming device comprises the following steps:

[0014] S1. Pre-sleeve the docking nut on the faucet, and use the engagement of the external thread of the docking nut and the fixing ring to quickly fix the housing on the faucet. Then, the user adds detergent, hand soap, laundry detergent, etc. into the liquid reservoir and seals the liquid reservoir with a rubber sealing cover. Then, the user rotates the knob to synchronously drive the two sets of valve plates on the two sets of manual valves to rotate. Since the valve plates of the two sets of manual valves are respectively arranged horizontally and vertically, when the water outlet pipe is in a closed state, the docking elbow is in a water-passing state. Then, the clean water is transmitted to the circular base through the docking elbow and the water outlet. At the same time, the clean water in the circular base is transmitted to the circular groove through the Venturi tube;

[0015] S2. Due to the characteristics of the Venturi tube, this effect is manifested in that when the restricted flow passes through a reduced flow cross-section, the fluid velocity increases. The flow velocity is inversely proportional to the flow cross-section. According to Bernoulli's principle: p + ρgh + (1 / 2) * ρv^2 = c (c is a constant), that is, the increase in flow velocity is accompanied by a decrease in fluid pressure, that is, low pressure is generated near the high-speed flowing fluid, thereby producing an adsorption effect. Therefore, point b can be affected by the liquid flow velocity in the Venturi tube, which can generate negative pressure and positive pressure;

[0016] S3. Due to the design of the cross valve, when negative pressure is generated, it will cause the cross valve to open, releasing the closed state of the cross valve, and the cleaning liquid such as detergent or hand soap in the liquid storage cylinder can be quickly sucked into the venturi tube through the drainage hole and mixed with the clean water. Due to the high flow rate, the mixed liquid will hit the cylinder wall at high speed and generate bubbles. Then, the mixed liquid and bubbles will be discharged together through the second liquid outlet, realizing the quantitative extraction of detergent, hand soap, laundry detergent, etc. and the generation of bubbles. At the same time, according to the characteristics of the cross valve, leakage can also be prevented;

[0017] S4. The device can also be used to connect to the water inlet of the washing machine, that is, the faucet. The installation method is as described in S1. Then the user connects and fixes the water inlet pipe of the washing machine to the docking ring, so that the mixed liquid in the first liquid outlet can quickly enter the washing machine. An air inlet pipe can be installed on the liquid suction end. The liquid suction end can be set on one side of the circular cover, and the air inlet pipe runs through the liquid storage cylinder and communicates with the atmosphere, so as to achieve the purpose of fully mixing the gas, clean water and cleaning liquid. At the same time, the entry of gas can accelerate the mixing speed between the two liquids and make the mixing more complete; and it can increase the bubbling effect of the cleaning liquid. A duckbill valve needs to be installed on the circular cover and the air inlet pipe. Prevent the sucked liquid and gas from entering the air inlet pipe and the liquid storage cylinder. When it reaches the mixing expansion part, turbulence can be formed inside to increase the degree of full mixing of the cleaning liquid and the water flow. The above method can also achieve quantitative extraction of laundry liquid, and after extraction, the clean water and laundry liquid can be fully mixed. Compared with traditional hand soaps that use electric or induction methods, there is no need to connect an additional power supply or induction chip. The whole process is carried out mechanically and based on physical principles. It does not require plugging in, batteries, or power supply, which is more environmentally friendly and energy-saving. In addition, the device does not require active pressing of hand soaps, laundry liquids, etc. by the human body, thereby reducing the chance of bacterial and fungal infections in the human body.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In the present invention, by setting a rotating knob, when the device is connected to an ordinary faucet, the opening and closing of the docking elbow and the water outlet can be controlled, so as to control the automatic foaming of each quantitative liquid aspiration. At the same time, the design of the cross valve can release the closed state of the liquid storage cylinder, so that the clean water can be transmitted to the circular groove through the Venturi tube. Due to the characteristics of the Venturi tube, negative pressure can be generated near the high-speed flowing fluid, which is convenient for quickly sucking the hand soap or dishwashing liquid in the liquid storage cylinder into the Venturi tube through the discharge hole, and mixing with the clean water, rushing out of the Venturi tube at high speed and impacting the opposite tube wall at high speed to generate bubbles, and then discharged together through the second liquid outlet, thereby achieving quantitative liquid aspiration. The device can extract detergent, hand soap, laundry detergent, etc. in a certain amount and foam automatically; and when the device is connected to the washing machine faucet, it only needs to rotate the cross valve once to extract the laundry detergent in a certain amount each time and automatically shut it off. This device is simple, effective and low-cost. Compared with the traditional methods of washing dishes, washing hands and washing clothes, the device can mix the cleaning liquid in a certain proportion and foam automatically, with stronger cleaning power, and achieve the best cleaning effect with the least cleaning liquid. It can save cleaning liquid and tap water, and can also prevent high-concentration cleaning liquid from damaging the skin or the cleaned items, and can reduce residue, protect health, facilitate public use, and improve the quality of life.

It can save cleaning liquid and tap water, and can also prevent high-concentration cleaning liquid from damaging the skin or the objects being cleaned, and can reduce residue, protect health, facilitate public use, and improve the quality of life.

[0038] A method for operating a non-electrical automatic quantitative mixing and foaming device comprises the following steps:

[0039] S1. Pre-sleeve the docking nut 6 on the faucet, and use the engagement of the external thread of the docking nut 6 and the fixing ring 3 to quickly fix the housing 1 on the faucet. Then, the user adds detergent or hand soap and laundry detergent into the liquid reservoir 13, and seals the liquid reservoir 13 with the rubber sealing cover 14. Then, the user can synchronously drive the two sets of valve plates on the two sets of manual valves 10 to rotate by rotating the knob 12. Since the valve plates of the two sets of manual valves 10 are respectively arranged horizontally and vertically, when the water outlet pipe 8 is in a closed state, the docking elbow 9 is in a water-passing state. Then, the clean water is transmitted to the circular base 2 through the docking elbow 9 and the water outlet 11. At the same time, the clean water in the circular base 2 is transmitted to the circular groove through the Venturi tube 19;

[0040] S2. Due to the characteristics of the Venturi tube 19, this effect manifests itself in an increase in the velocity of the fluid as the restricted flow passes through a reduced flow cross-section. The velocity is inversely proportional to the flow cross-section. According to Bernoulli's principle: p + ρgh + (1 / 2) * ρv^2 = c (c is a constant), that is, an increase in flow velocity is accompanied by a decrease in fluid pressure. In other words, low pressure is generated near the high-speed flowing fluid, resulting in adsorption. Therefore, point b can be affected by the liquid flow velocity in the Venturi tube 19, generating both negative and positive pressures.

[0041] S3. Due to the design of the cross valve 20, when negative pressure is generated, the cross valve 20 is prompted to open, releasing the closed state of the cross valve 20, and the cleaning liquid such as detergent or hand soap in the liquid storage cylinder 13 can be quickly sucked into the venturi tube 19 through the liquid discharge hole 22 and mixed with the clean water. Due to the high flow rate, the mixed liquid will hit the wall of the cylinder 18 at high speed and generate bubbles. Then, the mixed liquid and bubbles will be discharged together through the second liquid outlet 16, realizing the quantitative extraction of detergent, hand soap, laundry detergent, etc. and the generation of bubbles. At the same time, according to the characteristics of the cross valve 20, leakage can also be prevented;

[0042] S4. The device can also be used to connect the water inlet of the washing machine, that is, the faucet. The installation method is as described in S1. Then the user docks and fixes the water inlet pipe of the washing machine with the docking ring 23, so that the mixed liquid in the first liquid outlet 15 can quickly enter the washing machine, and an air inlet pipe can be added to the liquid suction end. The liquid suction end can be set on one side of the circular cover 17, and the air inlet pipe runs through the liquid storage cylinder 13 and communicates with the atmosphere, so as to achieve the purpose of fully mixing the gas, clean water and cleaning liquid. At the same time, the entry of gas can speed up the mixing speed between the two liquids and make the mixing more complete; and it can increase the bubbling effect of the cleaning liquid, and it is necessary to add a circular cover 17 and the air inlet pipe. The duckbill valve prevents the sucked liquid and gas from entering the air inlet pipe and the liquid storage cylinder 13. When it reaches the mixing expansion part, turbulence can be formed inside to increase the degree of full mixing of the cleaning liquid and the water flow. The above method can also achieve quantitative extraction of laundry liquid, and after extraction, the clean water and laundry liquid can be fully mixed. Compared with traditional hand soaps that use electric or inductive methods, there is no need to connect an additional power supply or induction chip. The whole process is carried out mechanically and based on physical principles. It does not require plugging in, batteries, or power supply, which is more environmentally friendly and energy-saving. In addition, the device does not require active pressing of hand soaps, laundry liquids, etc. by the human body, thereby reducing the chance of bacterial and fungal infections in the human body.

The first liquid outlet (15) is located in the docking ring (23).

2. The non-electrical automatic quantitative mixing and foaming device according to claim 1, characterized in that: A filter screen (4) is placed on the circular placement seat (7), an elastic washer (5) used in conjunction with the filter screen (4) is clamped in the fixing ring (3), and the bottom of the elastic washer (5) is clamped in the circular placement seat (7), and the top of the elastic washer (5) is fitted on the docking nut (6).

3. The operating method of the non-electrical automatic quantitative mixing and foaming device according to any one of claims 1-2, characterized in that: The steps include: S1. Pre-install the docking nut (6) on the faucet, and use the external thread of the docking nut (6) and the fixing ring (3) to quickly fix the shell (1) on the faucet. Then, the user adds detergent, hand soap or laundry detergent into the liquid storage cylinder (13), and uses the rubber sealing cover (14) to seal the liquid storage cylinder (13). Then, the user rotates the knob (12) to synchronously drive the two sets of valve plates on the two sets of manual valves (10) to rotate. Since the valve plates of the two sets of manual valves (10) are respectively arranged horizontally and vertically, when the outlet pipe (8) is in a closed state, the docking elbow (9) is in a water-passing state. Then, the clean water is transmitted to the circular base (2) through the docking elbow (9) and the water outlet (11). At the same time, the clean water in the circular base (2) is transmitted to the circular groove through the venturi tube (19); S2. Due to the characteristics of the Venturi tube (19), when the restricted flow passes through the reduced flow section, the fluid velocity increases, and the flow velocity is inversely proportional to the flow section. According to Bernoulli's law, p+ρgh+(1 / 2)*ρv^2=c, where c is a constant, that is, the increase in flow velocity is accompanied by a decrease in fluid pressure, that is, low pressure will be generated near the high-speed flowing fluid, thereby generating an adsorption effect. Therefore, the minimum flow section can be affected by the liquid flow velocity in the Venturi tube (19), generating negative pressure or positive pressure; S3. Due to the design of the cross valve (20), when negative pressure is generated, the cross valve (20) is prompted to open, releasing the closed state of the cross valve (20), and the detergent, hand soap or laundry detergent in the liquid storage cylinder (13) is quickly sucked into the venturi tube (19) through the discharge hole (22) and mixed with the clean water. Since the flow rate is very high, the mixed liquid will hit the wall of the cylinder (18) at high speed and generate bubbles. Then, the mixed liquid and the bubbles will be discharged together through the second liquid outlet (16); S4. The device can also be used to connect to the water inlet of a washing machine, i.e., the faucet. The installation method is as described in S1. Then, the user docks and fixes the water inlet pipe of the washing machine with the docking ring (23), so that the mixed liquid in the first liquid outlet (15) can quickly enter the washing machine. An air inlet pipe is installed at the liquid suction end. The liquid suction end is set on one side of the circular cover (17). The air inlet pipe passes through the liquid storage cylinder (13) and is connected to the atmosphere, so as to achieve the purpose of fully mixing the gas, purified water and laundry liquid. At the same time, the entry of gas can accelerate the mixing speed between the two liquids and make the mixing more complete; and increase the bubbling effect of the laundry liquid. A duckbill valve needs to be installed on the circular cover (17) and the air inlet pipe to prevent the sucked liquid and gas from entering the air inlet pipe and the liquid storage cylinder (13).
