Description

Technical Field

[0001] This invention relates to the field of bathroom technology, and in particular to a method for supplying liquid and generating foam in a bathing device. Background Technology

[0002] Existing shower systems are typically used for personal hygiene. However, with rising living standards, people have higher expectations for their bathing experience. Most current shower systems only offer basic water flow. When using shower gel or shampoo, one usually needs to wet their body and hair first, then remove the bottle, squeeze out the liquid, and apply it. The shower gel and shampoo don't flow out with the water, making it inconvenient and time-consuming. Furthermore, the shower gel and shampoo take up bathroom space and reduce the comfort of the bathing experience. Summary of the Invention

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a method for supplying liquid and foaming in a bathing device. This method overcomes the defects of the prior art and enables users to freely switch between clean water and bath liquids such as shower gel and shampoo according to their needs during bathing, making it convenient for users to use and greatly improving their bathing experience.

[0004] To solve the above problems, the technical solution of the present invention is as follows: A method for supplying liquid and generating foam in a bathing device, the bathing device comprising an air pump, a water filter chamber, a transfer chamber, a mixing and foaming chamber, a delivery pump, a storage bottle, and a solenoid valve; the water filter chamber is connected to the hot and cold valve of a water heater shower head via an inlet pipe and a pipeline, and the water filter chamber is connected to the mixing and foaming chamber via a pipeline with a solenoid valve; at least one set of storage bottles is provided for storing bathing products, and the bottom of each set of storage bottles is connected to the mixing and foaming chamber via a pipeline and a delivery pump; the air pump is connected to the mixing and foaming chamber via an air pipe, and the mixing and foaming chamber is provided with an outlet pipe; a foaming net is provided at the outlet of the mixing and foaming chamber; the outlet pipe is connected to the shower head via a pipeline; the solenoid valve has two settings: when energized, the flow path inside the solenoid valve is fully open, and when de-energized, the cross-sectional area of ​​the flow path inside the solenoid valve becomes 1 / 49-1 / 225 of the fully open size; or, when de-energized, the flow path inside the solenoid valve is fully open, and when energized, the cross-sectional area of ​​the flow path inside the solenoid valve is 1 / 49-1 / 225 of the fully open size; Includes the following steps: S1. When clean water is needed, turn on the shower head hot and cold valve, adjust the water temperature, and control the solenoid valve to open the flow path inside the solenoid valve. Clean water enters the filter chamber through the inlet pipe, then enters the mixing and foaming chamber, and is delivered to the shower head through the outlet pipe and sprayed out from the shower head. S2. When the bath products stored in the reservoir are needed, turn on the shower head hot and cold valve to adjust the water temperature and control the energization / de-energization of the solenoid valve. This makes the cross-sectional area of ​​the flow path inside the solenoid valve 1 / 49-1 / 225 of its fully open state, allowing clean water to enter the mixing and foaming chamber. At the same time, turn on the delivery pump corresponding to the required reservoir bottle. Control its power through current to control the delivery speed of the liquid in the reservoir bottle, thereby controlling the liquid supply and adjusting the areal density of the foam, and allowing it to also enter the mixing and foaming chamber. Simultaneously, start the air pump to supply air. The clean water and bath products are impacted and mixed in the mixing and foaming chamber under the action of airflow. They are then formed into bubbles through the internal foaming net and output from the outlet pipe, sprayed out by the shower head. When you need clean water again, simply switch back to step S1.

[0005] The solenoid valve is a normally open two-position two-way solenoid valve. When de-energized, the cross-sectional area of ​​the two-position two-way solenoid valve is fully open. When energized, by setting the valve closing position, the cross-sectional area of ​​the flow path of the two-position two-way solenoid valve becomes 1 / 49-1 / 225 of the fully open cross-sectional area. It may be a normally closed two-position two-way solenoid valve. When energized, the cross-sectional area of ​​the two-position two-way solenoid valve is fully open. When de-energized, by setting the valve closing position, the cross-sectional area of ​​the flow path of the two-position two-way solenoid valve becomes 1 / 49-1 / 225 of the fully open cross-sectional area. Alternatively, the solenoid valve is a two-position three-way solenoid valve, including an inlet, a large outlet, and a small outlet, the diameter of the small outlet being 1 / 7 to 1 / 15 of the diameter of the other large outlet; when energized, the large outlet is closed and the small outlet is open, and when de-energized, the large outlet is open and the small outlet is closed; or, when energized, the small outlet is closed and the large outlet is open, and when de-energized, the large outlet is closed and the small outlet is open. Alternatively, the solenoid valve is a concentrated water solenoid valve, including an inlet, a small outlet, and a large outlet. Regardless of whether it is energized or de-energized, the small outlet is always open; when energized, the large outlet is open; when energized, the cross-sectional area of ​​the flow path is 49-225 times the cross-sectional area of ​​the small outlet.

[0006] The solenoid valve includes a valve body, an iron plate, an iron sleeve, a coil, a cover plate, a sliding sleeve, and a sealing cap. The iron plate covers the top surface of the valve body. An iron sleeve is fixedly installed at the center of the top surface of the iron plate.

The sealing ring forms a sealed sliding fit with the inner side wall of the movable cavity. A convex tube is provided in the center of the top surface of the cover, penetrating its top and bottom surfaces. The upper opening of the convex tube is higher than the cover. The sliding sleeve contains, from top to bottom, a moving iron core, spring B, and a top block. A limiting ring is located at the lower end of the sliding sleeve. The top block is frustum-shaped, with its lower end face being the top surface of the frustum. The diameter of the through hole at the center of the limiting ring is larger than the diameter of the top surface of the frustum but smaller than the diameter of the bottom surface. When power is off, the lower end face of the top block extends from the center outlet of the limiting ring, and spring B only supports the moving iron core. Under gravity, the lower end face of the top block slightly contacts the upper end of the convex tube. When power is on, the iron sleeve generates magnetic force under the action of the coil, causing the moving iron core to move downwards, pushing the top block against the upper end of the convex tube, thus sealing the upper end of the convex tube. The cover plate has a through hole on one side of its bottom surface that connects to the movable cavity; the lower part of the central pipe has a sealing platform that completely seals the valve outlet; the side wall of the central pipe has a side opening that communicates with the interior of the sealing platform; the top surface of the sealing platform has a pinhole that connects the annular channel and the interior space of the sealing platform; the cross-sectional area of ​​the pinhole is equivalent to 1 / 49 to 1 / 225 of the cross-sectional area of ​​the side opening.

[0038] The working process of this embodiment is as follows: During normal water rinsing, the solenoid valve 7 is energized, while the delivery pump 5 and air pump 1 are de-energized. When energized, the flow path inside the two-position two-way solenoid valve 7 is fully open. After the clean water enters the filter chamber 2 through the inlet pipe 8, it is filtered by the water quality filter element and then enters the transfer chamber 3, then the mixing and foaming chamber 4. Finally, the clean water flows to the shower head through the outlet pipe 8 and is sprayed out from the shower head. When shampoo is needed, the user disconnects the solenoid valve power switch. At this time, the two-position two-way solenoid valve 7 is in the de-energized state. When the power is off, the cross-sectional area of ​​the flow path inside the solenoid valve 7 is 1 / 180 of the fully open state. At the same time, the air pump 1 is in the energized state. The delivery pump 5 corresponding to the shampoo storage bottle 6 draws shampoo from the liquid outlet of the storage bottle 6 and pumps it into the mixing foam chamber 4. The air pump 1 supplies air to the mixing foam chamber 4. The water and shampoo are impacted and mixed in the mixing foam chamber 4 under the action of airflow, and form bubbles through the internal foaming net. The bubbles are output from the outlet pipe 9 and sprayed out by the shower head. When shower gel is needed, the user disconnects the solenoid valve power switch. At this time, the two-position two-way solenoid valve 7 is in the de-energized state. When the power is off, the cross-sectional area of ​​the flow path inside the solenoid valve 7 is 1 / 180 of the fully open state. At the same time, the air pump 1 is in the energized state. The delivery pump 5 corresponding to the shower gel storage bottle 6 draws the shower gel from the outlet of the storage bottle 6 and pumps it into the mixing foam chamber 4.

Regardless of whether it is energized or de-energized, the small outlet is always open; when energized, the large outlet is open; when energized, the cross-sectional area of ​​the flow path is 49-225 times the cross-sectional area of ​​the small outlet.

[0050] The working process of this embodiment is as follows: During normal clean water rinsing, open solenoid valve 7 and close delivery pump 5 and air pump 1. When powered on, the large outlet of concentrated water solenoid valve 7 is open and the small outlet is always open. At this time, water can flow out from both the small outlet and the large outlet at the same time. The cross-sectional area of ​​the flow path is fully open. After the clean water enters the filter chamber 2 through the inlet pipe 8, it is filtered by the water quality filter element and then enters the transfer chamber 3, then enters the mixing and foaming chamber 4. Finally, the clean water flows to the shower head through the outlet pipe 8 and sprays out from the shower head. When shampoo is needed, disconnect the power supply to the solenoid valve and turn on the power supply to the delivery pump 5 and the air pump 1. When the power is off, the large outlet of the concentrated water solenoid valve 7 is closed. At this time, the water can only flow out from the small outlet, and the cross-sectional area of ​​the flow path is 1 / 121 of the fully open size. At the same time, the air pump 1 is energized. The delivery pump 5 corresponding to the shampoo storage bottle 6 draws the shampoo from the liquid outlet of the storage bottle 6 and pumps it into the mixing foaming chamber 4. The air pump 1 supplies air to the mixing foaming chamber 4. The water and shampoo are impacted and mixed in the mixing foaming chamber 4 under the action of the airflow, and form bubbles through the internal foaming net. The bubbles are output from the outlet pipe 9 and sprayed out by the shower head. When conditioner is needed, disconnect the power supply to the solenoid valve and turn on the power supply to the delivery pump 5 and the air pump 1. When the power is off, the large outlet of the concentrated water solenoid valve 7 is closed. At this time, the water can only flow out from the small outlet, and the cross-sectional area of ​​the flow path is 1 / 121 of the fully open size. At the same time, the air pump 1 is energized. The delivery pump 5 corresponding to the liquid storage bottle 6 containing the conditioner draws the shower gel from the liquid outlet of the liquid storage bottle 6 and pumps it into the mixing foaming chamber 4. The air pump 1 supplies air to the mixing foaming chamber 4. The clean water and shower gel are impacted and mixed in the mixing foaming chamber 4 under the action of the airflow, and form bubbles through the internal foaming net. The bubbles are output from the outlet pipe 9 and sprayed out by the shower head. When shower gel is needed, disconnect the power supply to the solenoid valve and turn on the power supply to the delivery pump 5 and air pump 1. When the power is off, the large outlet of the concentrated water solenoid valve 7 is closed, and the water can only flow out from the small outlet. The cross-sectional area of ​​the flow path is 1 / 121 of the fully open size. At the same time, the air pump 1 is energized. The delivery pump 5 corresponding to the shower gel storage bottle 6 draws the shower gel from the outlet of the storage bottle 6 and pumps it into the mixing foaming chamber 4. The air pump 1 supplies air to the mixing foaming chamber 4. The clean water and shower gel are impacted and mixed in the mixing foaming chamber 4 under the action of the airflow, and form bubbles through the internal foaming net. The bubbles are output from the outlet pipe 9 and sprayed out by the shower head.
