Description

Technical Field

[0001] The present invention belongs to the technical field of showers, and particularly relates to a multifunctional steady-flow oxygen-enriched water-saving shower system. Background Art

[0002] The water flow rate of traditional shower heads is controlled by controlling the flow rate of the faucet to control the water flow rate of the shower head under different water spray modes. Currently, most shower heads on the market usually do not have the function of adjusting the flow rate. Most of them use angle valves to achieve switching and controlling the water output. Since the water output can only be determined by the degree of opening the angle valve, it is difficult to control and inaccurate. It not only wastes time, but also cannot accurately and quickly adjust to obtain the required flow rate. When actually using water, when the water pressure is low, the water output is too low, affecting the use; when the water pressure is high, the water output exceeds its actual demand, causing a large amount of waste. Summary of the Invention

[0003] Aiming at the defects of the above traditional shower heads, the purpose of the present invention is to provide a multifunctional steady-flow oxygen-enriched water-saving shower system, which has a simple structure, reasonable design, practical convenience, water-saving and comfort.

[0005] Among them, both the overhead shower head and the handheld shower head are provided with a shower head having a hollow structure. An air cavity, an engine water cavity and a water distribution cavity are provided in the shower head.

[0007] A water transmission separation layer separating the two is provided between the engine water cavity and the water distribution cavity. The water transmission separation layer is provided with a plurality of water inlet protrusions corresponding to the air outlet pipes one by one. The water inlet protrusions are provided with water inlet holes communicating the engine water cavity and the water distribution cavity.

[0008] The air outlet pipes extend into the water inlet holes one by one, and the air outlet ends of the air outlet pipes are relatively close to the water outlet ports of the water inlet holes. A gap for guiding the water flow in the engine water cavity to the water distribution cavity is formed between the outer wall of the air outlet pipe and the inner wall of the water inlet hole.

[0009] The bottom end of the surface-mounted lifting pipe is provided with a water distributor. The overhead shower is connected to the water distributor through the surface-mounted lifting pipe, and the hand-held shower is connected to the water distributor through a flow-stabilizing restrictor. The water inlet pressure of the hand-held shower is controlled by the flow-stabilizing restrictor. An outlet channel is provided inside the water distributor, and the water output of the overhead shower and the hand-held shower is controlled respectively by adjusting the angle of the water distributor.

[0010] Further, when the water distributor rotates clockwise by 120°, the hand-held shower discharges water. When the water distributor is in the middle position, the water output of the overhead shower is 9.5 ± 0.1 L / min. When the water distributor rotates counterclockwise by 120°, the water output of the overhead shower is 4.75 ± 0.1 L / min.

[0011] Further, a sliding body is provided in the middle of the surface-mounted lifting pipe. One end of the sliding body is open and the other end is closed. The water inlet of the hand-held shower is connected to the end of the vertical shower hose through a flow-stabilizing restrictor. The hand-held shower is inserted into the opening on the side of the sliding body and is limited by the end shell of the vertical shower hose. The head end of the vertical shower hose is connected to the water distributor.

[0012] Further, the water outlet side of the shower head is set as a water outlet wall, and a number of water outlet holes communicating with the water distribution cavity are provided on the water outlet wall.

[0013] Further, a cylindrical upper support tube is provided at the upper end of the surface-mounted lifting pipe. The overhead shower passes through the middle of the upper support tube through a horizontal shower hose. The horizontal shower hose is connected to the overhead shower through a spherical joint at its end, and the rotation angle is ±15°.

[0014] Further, the sliding body is slidably sleeved on the middle of the surface-mounted lifting pipe.

Detailed implementation mode

[0030] The present invention provides a multifunctional flow-stabilizing oxygen-enriched water-saving shower system.

[0031] As Figure 1 and Figure 2 shown, the multifunctional flow-stabilizing oxygen-enriched water-saving shower system of the present invention includes a hollow surface-mounted lift pipe 2, an overhead shower 5 installed at the top end of the surface-mounted lift pipe 2, and a hand-held shower 6 installed in the middle of the surface-mounted lift pipe 2.

[0032] Among them, both the overhead shower 5 and the hand-held shower 6 are provided with a shower head 9 having a hollow structure. The shower head 9 uses the pressure difference generated by the Venturi effect to press air into the water passage, and the air and water are fully mixed, so as to achieve the effect of oxygen enrichment and water saving. Specifically, an air chamber 91, an engine water chamber 92 and a water distribution chamber 93 are provided in the shower head 9. Among them, the air chamber 91 is located above the engine water chamber 92, and the water distribution chamber 93 is located in front of the engine water chamber 92. In order to cooperate with the Venturi effect and increase the process of air and water mixing, the engine water chamber 92 extends from the shower arm to the shower head 9 and is located below the air chamber 91. When the shower water enters through the engine water chamber 92, a pressure difference will be caused. At this time, air is injected from top to bottom through the air chamber 91 to mix with water, achieving the purpose of oxygen enrichment and water saving. Specifically, the overhead shower 5 and the hand-held shower 6 utilize the Venturi effect. This effect is manifested in that when a restricted flow passes through a reduced cross-section of the flow passage, the fluid shows an increase in flow velocity, and its flow velocity is inversely proportional to the cross-section of the flow passage. Simply put, this effect means that a low pressure will be generated near a high-speed flowing fluid, thereby generating an adsorption effect. Using this effect, a change in the pipe cross-section is set on the water inlet pipeline of the shower to inject external air into the shower water, forcing the water flow to accelerate, achieving the effect of water saving. The hand-held shower 6 has two water outlet modes. Among them, the oxygen-enriched mode means that an air chamber 91 is provided in the water inlet channel of the shower head 9 to increase the process of full mixing of air and water. Compared with the ordinary mode, it can save flow rate and make the sprayed water droplets softer and more comfortable. At the same time, the engine water chamber 92 in the shower can ensure that the highest standard of accurate and continuous water volume distribution can be achieved for each water outlet hole, so that the water is evenly mixed with air and the water droplets are full when spraying out of the shower, ensuring a comfortable body feeling while reducing the water consumption during bathing.

[0033] The upper surface of the shower head 9 is provided with a plurality of air-permeable holes communicating with the air cavity 91, and the engine water cavity 92 is communicated with the water delivery pipeline of the shower head 9; there is a gas-water separation layer 94 separating the two between the air cavity 91 and the engine water cavity 92, and the gas-water separation layer 94 is provided with a plurality of air outlet pipes 941 located in the engine water cavity 92; there is a water delivery separation layer 95 separating the two between the engine water cavity 92 and the water distribution cavity 93, and the water delivery separation layer 95 is provided with a plurality of water inlet protrusions 951 corresponding to the air outlet pipes 941 one by one, and the water inlet protrusions 951 are provided with water inlet holes 9511 communicating the engine water cavity 92 and the water distribution cavity 93; the air outlet pipes 941 extend into the water inlet holes 9511 one by one, and the air outlet end of the air outlet pipe 941 is relatively close to the water outlet port of the water inlet hole 9511, and a gap for guiding the water flow in the engine water cavity 92 to the water distribution cavity 93 is formed between the outer wall of the air outlet pipe 941 and the inner wall of the water inlet hole 9511; the bottom end of the surface-mounted lifting pipe 2 is provided with a water distributor 4, the overhead shower 5 is communicated with the water distributor 4 through the surface-mounted lifting pipe 2, and the hand-held shower 6 is communicated with the water distributor 4 through the flow-stabilizing restrictor 8, and the water inlet pressure of the hand-held shower 6 is controlled through the flow-stabilizing restrictor 8. In fact, the flow-stabilizing and restricting technology can adjust the water inlet pressure of the shower within a certain range. The basic principle of the flow-stabilizing restrictor 8 is to achieve the effect of flow stabilization through the combination of the water passing channel and the elastic structure. The elastic structure will produce different deformation amounts under different water pressures, thereby changing the cross-sectional area of the water passing channel. Under the combination of the deformation amount and the structure of the water passing channel itself, the corresponding water outlet size is changed, achieving the effect of pressure stabilization and throttling, and can keep the water outlet flow rate of the shower constant.

[0034] In fact, the interior of the water distributor 4 is provided with three water outlet channels, and the water output of the hand-held shower 6 and the overhead shower 5 are respectively controlled by adjusting the angle of the water distributor 4. The water distributor 4 can be used to switch between using the hand-held shower 6, the overhead shower 5 and the water-saving of the overhead shower 5. The water-saving channel in the water distributor 4 reduces the water inlet flow rate into the shower by reducing the cross-sectional area of the water passing channel, achieving the purpose of water saving. The water distributor 4 is used to adjust the water outlet mode of the shower, such as Figure 3 、 Figures 4a to 4c shown, when the knob of the water distributor 4 rotates clockwise by 120°, Figure 4a channel ① in the middle is opened and the hand-held shower 6 discharges water; when the knob of the water distributor 4 rotates counterclockwise by 120°, Figure 4c only channel ② in the middle is opened, and the overhead shower 5 discharges water in a water-saving manner, with the water output of 4.75 ± 0.1 L / min, preferably 4.75 L / min, and the flow rate is saved by up to 50%; when the knob of the water distributor 4 is in the middle position, Figure 4bThe middle channels ② and ③ are opened, and the overhead shower 5 discharges water with a water flow rate of 9.5 ± 0.1 L / min, preferably 9.5 L / min. Among them, an air cavity 91, an engine water cavity 92, and a cleaning nozzle are provided inside the shower heads 9 of both the overhead shower 5 and the hand-held shower 6. The air injection technology generated by the Venturi effect can reduce the water consumption during the flushing process, achieving a water-saving effect. In this system, the air injection position is the shower head 9. An engine water cavity 92 is provided inside the shower head 9 to ensure that the highest standard of precise and continuous water volume distribution can be achieved for each water outlet hole of the shower. The front end water outlet of the shower uses medical rubber, which can quickly clean the nozzle and prevent scale.

[0035] As a preferred embodiment of the present invention, the sliding body 3 is slidably sleeved in the middle of the surface-mounted lifting pipe 2. One end of the sliding body 3 is open and the other end is closed. The water inlet of the hand-held shower 6 is communicated with the end of the vertical shower hose 7 through a flow-stabilizing restrictor 8. The hand-held shower 6 is inserted into the opening on the side end of the sliding body 3 and is limited by the end housing of the vertical shower hose 7. The head end of the vertical shower hose 7 is communicated with the water distributor 4. As Figure 5 shown, the end of the vertical shower hose 7 is self-equipped with a filter gasket 71.

[0036] As a preferred embodiment of the present invention, the water outlet side of the shower head 9 is set as a water outlet wall 96, and a plurality of water outlet holes 961 communicating with the water distribution cavity 93 are provided on the water outlet wall 96.

[0037] As a preferred embodiment of the present invention, the upper end of the surface-mounted lifting pipe 2 is provided with a cylindrical upper support tube 21. The overhead shower 5 passes through the middle of the upper support tube 21 through the horizontal shower hose 1. The horizontal shower hose 1 is connected to the overhead shower 5 through its end spherical joint, and the rotatable angle is ±15°.

[0038] As a preferred embodiment of the present invention, the inlet hose communicating with the water distributor 4 is a DN15 threaded hose with a length of 1250 ± 10 mm, and the minimum flow rate is 7 ± 1 L / min, preferably 7 L / min; it can be connected to a water supply faucet or a wall outlet elbow.

[0039] As a preferred embodiment of the present invention, the diameter of the overhead shower 5 is 200 ± 10 mm, preferably 200 mm; the diameter of the hand-held shower 6 is 100 ± 10 mm, preferably 100 mm; the length of the horizontal shower hose 1 is 390 ± 10 mm, preferably 390 mm; the vertical distance between the upper support tube 21 and the horizontal shower arm is 116 ± 10 mm, preferably 116 mm; the vertical distance between the water distributor 4 and the upper support tube 21 is 620 ± 10 mm, preferably 620 mm.

[0040] As a preferred embodiment of the present invention, the stable flow restrictor 8 is a plastic ring with an internal rubber ring. The cross-sectional area of the water passage is controlled by the elastic deformation of the rubber ring, so as to adjust the phenomenon of excessive water flow such as jetting that may occur when the water pressure suddenly increases, and can also effectively prevent water resource waste.

[0041] The key water-saving indicators of the shower head include flow rate and flow rate uniformity. The influencing factors usually include the pressure of the water supply pipe network, the flow-limiting effect of the flow restrictor, and the internal structure of the shower head body. The multi-functional stable flow oxygen-enriched water-saving shower system provided by the present invention optimizes the internal structure of the stable flow restrictor and the shower head body, and combines oxygen-enriching technology, stable flow technology, water-saving technology, and comfort testing to provide a shower system that can simultaneously achieve water-saving performance and usage performance and meet the comfort requirements of users.
