[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0032] like Figures 1 to 6 As shown, the present invention discloses a non-electric foaming showerhead. Its overall design realizes its core function through water flow, enabling it to provide the necessary foaming function for bathing without power supply. The device utilizes an ingenious mechanical structure design to solve the problems of high energy consumption, high noise, and high maintenance costs of traditional electrically driven showerheads, making it suitable for use in homes, outdoors, and other environments.

[0033] The foaming bathtub comprises a bathtub body 1, internally provided with a main valve assembly 2 for controlling the mixing of cold and hot water and the subsequent water distribution. The output end of the main valve assembly 2 is connected to a shower assembly 3, comprising a shower valve 31 and a shower head 32, for evenly spraying the mixed foam water onto the user, providing a pleasant bathing experience.

[0034] The shower assembly 3 is connected to a foaming device. This device is a core component of the present invention, mixing water, air, and a cleaning solution (such as soap or shower gel) to produce rich foam. The foaming device includes a mixing valve 4, a mixing chamber 5, an air supply structure 6, a water supply line 7, and a soap supply structure 8.

[0035] The mixing valve 4 is located between the main valve assembly 2 and the mixing cavity 5, and is used to control the water flow into the mixing cavity 5, and at the same time provide driving force for the air supply structure 6 and the soap supply structure 8 (the air supply structure 6 and the soap supply structure 8 are both driven by water flow).

[0036] The mixing cavity 5 is a key component for mixing water, gas and cleaning liquid to achieve foaming. Its output end is connected to the shower assembly 3, and its input end is respectively connected to the air supply structure 6, the water supply pipeline 7 and the soap supply structure 8. The interior of the mixing cavity 5 adopts a spiral guide plate 51 and a refinement network structure (such as a refinement network 52) to enhance the mixing efficiency and make the foam more uniform and delicate. The spiral guide plate 51 causes the water flow to form a vortex motion in the cavity, thereby enhancing the interaction between water, gas and cleaning liquid; the refinement network 52 further refines the foam, making the output foam more uniform and delicate, and improving the user experience. The output end of the mixing cavity is also provided with a third one-way valve (not shown in the figure) to prevent the water at the shower from flowing back into the cavity, thereby ensuring the long-term and stable operation of the device.

[0037] Further, such as Figure 5As shown, the mixing chamber 5 is further provided with a stirring assembly 53, which is preferably driven to rotate by water flow. Specifically, the stirring assembly 53 includes a rotating shaft 531, a plurality of spiral blades 532 mounted on the rotating shaft 531, and a plurality of stirring blades 533 mounted on the rotating shaft 531. The paddle blades 532, under the impact of the water flow, can drive the stirring blades 533 to rotate, thereby stirring the gas-liquid mixture in the mixing chamber 5 and accelerating gas-liquid mixing.

[0038] The gas supply structure 6 includes a gas-liquid exchanger 61, a device that generates gas by exchanging gas and liquids driven by water flow. The gas-liquid exchanger includes a gas-liquid exchange container 611. The top of the gas-liquid exchange container 611 is connected to the mixing chamber 5 via a gas pipe 612, and the bottom of the container is connected to the mixing valve 4 via a water inlet pipe 62.

[0039] A one-way valve 6121 is provided on the gas delivery pipe 612 to prevent the water or gas in the mixing cavity 5 from flowing back.

[0040] During operation, water flows through the water inlet pipe 62 into the gas-liquid exchange container 611 , squeezes the air at the top of the container to the air delivery pipe 612 , and transmits it to the mixing cavity 5 to participate in foaming.

[0041] The bottom of the gas-liquid exchange container 611 is also provided with a drainage structure. After the air is exhausted, it can be opened in time to discharge the remaining water in the container, so as to facilitate the smooth progress of the next gas-liquid exchange.

[0042] Preferably, in order to replenish some gas during the gas-liquid exchange process, the present invention designs a Venturi tube at the water inlet pipe 62, which can use the Venturi effect to automatically inhale air when water flows through, thereby achieving effective gas replenishment.

[0043] Specifically, the water inlet pipe 62 includes a Venturi tube 621. An air supply pipe 622 is provided on the sidewall of the throat of the Venturi tube 621, connecting the inner cavity of the Venturi tube 621 with the outside world. The air supply pipe 622 is equipped with a first one-way valve 623. The water inlet pipe 62 of the gas-liquid exchanger is designed in the form of a Venturi tube. An air supply pipe 66 is provided on the sidewall of the throat of the Venturi tube. As water flows through, it draws in air using the negative pressure created. The first one-way valve 623 prevents gas backflow. This design generates a stable gas flow without the need for additional power, thereby replenishing gas to the gas-liquid exchange container 611 and significantly extending the gas-liquid exchange time.

[0044] The water supply line 7 is connected to the mixing valve 4, which is used to introduce a constant water flow into the mixing chamber 5. A water constant flow valve 71 is installed in the water supply line to ensure the stability of the water flow rate and prevent imbalances in the mixing ratio caused by water pressure fluctuations, thereby further ensuring the consistency of foam quality. The water constant flow valve 71 is a common constant flow valve on the market and is a state of the art, so it will not be described in detail here.

[0045] The soap supply structure 8 provides a steady supply of cleaning liquid to the foaming device. It includes a soap bottle 81 that stores the cleaning liquid and a water-driven hydraulic pump 82. The hydraulic pump 82 utilizes water flow as a driving force, pumping cleaning liquid from the soap bottle through an internal mechanical transmission and delivering it to the mixing chamber 5.

[0046] The present invention achieves fully mechanical foaming by driving the air supply structure 6, soap supply structure 8 and mixing cavity 5 with water flow, without relying on electricity. The foaming effect of the device is delicate and stable, with the following advantages:

[0047] 1. Energy saving and environmental protection: make full use of water flow energy, no external power supply is required, and energy consumption is reduced.

[0048] 2. Low-noise operation: Motor-free design significantly reduces operating noise and improves user experience.

[0049] 3. Low maintenance cost: The all-mechanical structure design reduces the maintenance and replacement requirements of electrical components.

[0050] 4. Wide range of applicable scenarios: It can be used in various scenarios such as daily bathing at home, outdoor activities, camping, etc., and is especially suitable for environments with lack of power supply.

[0051] In summary, the present invention provides a non-electric foaming shower head with clever design and reliable performance, which effectively solves the pain points of traditional shower heads in terms of energy consumption, noise and maintenance, and provides users with a new green and energy-saving bathing experience.

[0052] Furthermore, the drainage structure 63 ensures that the gas-liquid exchanger can quickly drain residual water after each gas-liquid exchange, maintaining internal cleanliness and efficient operation. The drainage structure 63 includes a drain pipe 631 located at the bottom of the gas-liquid exchange container 611 and a drain valve 632 located on the drain pipe 631. The drain pipe 631 is connected to the bottom of the gas-liquid exchange container 611 via a pipeline. When the drain valve 632 is opened, the accumulated water in the container can be quickly drained.

[0053] To further enhance drainage efficiency, the top of the gas-liquid exchange container 611 is provided with a gas-injection hole 633 for replenishing gas. This gas-injection hole 633 is structurally integrated with a second one-way valve 634. Through the cooperation of the gas-injection hole 633 and the second one-way valve 634, when the drain valve 632 is opened, the accumulated water in the container can be smoothly drained.

[0054] Furthermore, to optimize the user experience, a knob 41 is provided on the mixing valve 4. It is noteworthy that the knob 41 facilitates the synchronous control of the mixing valve 4 and the drain valve 632. Specifically, the knob 41 and the drain valve 632 are connected via a transmission structure 411. The transmission structure 411 adopts a mechanical connecting rod design or a gear transmission design (selectable according to actual needs), which can transmit the rotation of the knob 41 to the drain valve 632, realizing the coordinated operation of the two valves.

[0055] The knob 41 is designed to function as follows: when the user rotates the knob 41 to open the mixing valve 4, the transmission mechanism 411 simultaneously closes the drain valve 632, ensuring that water flows smoothly into the gas-liquid exchange container 611 and the subsequent mixing chamber 5, thereby initiating the gas-liquid exchange and foam generation process. Conversely, when the user rotates the knob 41 to close the mixing valve 4, the transmission mechanism 411 automatically opens the drain valve 632, quickly draining any remaining water from the gas-liquid exchange container 611. This design greatly simplifies the operation process and avoids the need for the user to separately adjust the drain valve.

[0056] Through the above structural design, not only the automatic drainage function of the gas-liquid exchanger is effectively realized, but also the intelligent linkage of the mixing valve and the drain valve can be realized during operation, thereby improving the convenience and user experience of the whole machine.

[0057] Furthermore, the hydraulic pump 82 includes a pump housing 821, the interior of which is divided into a main chamber 822 and a secondary chamber 823. The main chamber 822 is used to introduce water flow drive and generate rotational energy, while the secondary chamber 823 is responsible for driving the gear pump 827 through mechanical linkage to achieve the pumping function of the cleaning liquid.

[0058] The main chamber 822 is connected to a driving water path 825 for introducing water flow. An impeller 824 is provided in the main chamber 822, which generates rotational power by the impact of the fluid. The driving water path 825 is connected to the mixing valve 4 to ensure that the water flows from the mixing valve into the main chamber and drives the impeller to rotate at high speed. A driving shaft 826 is provided at the center of the impeller 824. The driving shaft passes through the main chamber 822 in the up and down directions. The other end of the driving shaft 826 extends to the sub-chamber 823. A gear pump 827 driven by the driving shaft is provided in the sub-chamber 823. The gear pump 827 is composed of a gear set and is driven by the driving shaft 826 to achieve synchronous rotation. It can efficiently extract the cleaning liquid in the soap bottle 81 and transport it to the mixing chamber 5 through a pipeline, where it is fully mixed with the water flow to generate uniform and fine foam. This design eliminates the complexity and energy consumption problems of traditional motor drive through the combination of hydraulic drive and mechanical linkage, thereby improving the stability and energy efficiency of the system.

[0059] Furthermore, to ensure efficient water flow, the lower end of the main chamber 822 is provided with a plurality of water inlets 8221. These inlets 8221 can evenly introduce water flow to drive the rotation of the impeller 824. Simultaneously, the sidewalls of the main chamber 822 are provided with a plurality of water outlets 8222. These outlets direct water flow from the main chamber, forming a stable water flow path. The distribution of the water inlets 8221 and outlets 8222 effectively prevents the generation of eddies and turbulence, thereby improving the overall efficiency of the hydraulic pump. Of course, the positions of the water inlets 8221 and outlets 8222 can be interchanged.

[0060] To ensure the rotational stability of the impeller 824 , the drive shaft 826 is connected to rotate in the middle of the main chamber 822 in the up and down directions.

[0061] Through the above design, the hydraulic pump 82 can achieve efficient operation under fluid drive, and at the same time, the gear pump 827 in the auxiliary cavity 823 can complete the automatic extraction and delivery of the cleaning liquid.

[0062] Furthermore, the main valve assembly 2 includes a hot water interface 21, a cold water interface 22, a thermostatic valve 23 and a main pipe 24. The main pipe 24 connects the mixing valve 4 and the shower assembly 3. The shower assembly 3 includes a shower valve 31 and a shower head 32.

[0063] The main valve assembly 2 further includes a lower water outlet valve connected to the main pipeline 24 .
