Description

Technical Field

[0001] This utility model belongs to the technical field of bathroom products, specifically relating to a water-saving device and a shower system. Background Technology

[0002] Currently, the shower systems commonly used in homes, hotels, and public bathrooms mainly consist of a water heater, water pipes, and a shower head. They operate by directly connecting the water heater to the shower head via water pipes to deliver and supply hot water. However, in practical applications, this type of shower system suffers from significant water waste, specifically in the following two key aspects:

[0003] Firstly, during the shower startup phase, because the water pipes still contain residual cold water from the previous use, users must wait for all the cold water in the pipes to drain completely after turning on the showerhead, until the hot water from the water heater reaches the showerhead and the water temperature is adjusted to a suitable level before they can officially start showering. During this period, the cold water flowing from the showerhead is not collected by any device and is directly discharged into the sewer, resulting in the unnecessary waste of this usable water resource.

[0004] Secondly, during showering, when users apply shower gel or rub their bodies, to prevent the water heater from stopping and then restarting due to temperature fluctuations in the pipes—resulting in a flow of hot residual water followed by cold water that hasn't reached the set temperature—users typically turn the shower head towards the wall, allowing water to flow continuously unused until they finish applying and rubbing their skin, before turning the shower head back. This process further increases water waste.

[0005] Therefore, existing shower systems cause a significant waste of water resources during use, and there is an urgent need for a technical solution that can effectively address the problem of water waste during showering. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, a water-saving device and shower system are provided, which solves the problem that the existing shower system will cause a lot of water waste during use.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A water-saving device includes a water distribution switch and a water storage tank. A mixing device is installed on the water storage tank. The water distribution switch is connected to the water storage tank and the mixing device through an inlet pipe. An automatic switching mechanism is installed inside the water storage tank to control the water inlet and outlet of the water storage tank.

[0009] With the above structural design, the water-saving device is installed between the faucet and the shower head of the shower system. When first used, cold water can be directly introduced into the water storage tank for temporary storage through the water diversion switch, at which time the outlet of the water storage tank is closed. When the cold water is exhausted, the water diversion switch is switched to introduce hot water into the mixing device. At the same time, the automatic switching mechanism installed in the water storage tank automatically controls the water inlet of the water storage tank to close and the water outlet to open, so that the cold water in the water storage tank is mixed with the hot water in the mixing device, thereby achieving the purpose of saving water during showering.

[0010] Preferably, the inlet of the water storage tank is connected to the inlet pipe, and the outlet of the water storage tank is connected to the mixing device.

[0011] Preferably, the automatic switching mechanism includes a slide rod installed on the inner wall of the water storage tank, a connecting rope movably mounted on the slide rod, and a first gravity ball and a second gravity ball connected to both ends of the connecting rope, respectively. A first limiting member and a second limiting member are respectively provided at the water inlet and the water outlet of the water storage tank, and the first gravity ball and the second gravity ball are respectively disposed within the first limiting member and the second limiting member to block the water inlet or the water outlet.

[0012] Preferably, the weight of the first gravity ball is greater than the weight of the second gravity ball.

[0013] With the above structural design, the automatic switching mechanism uses a first gravity ball and a second gravity ball to block the inlet or outlet of the water, respectively. Initially, due to the greater weight of the first gravity ball, the inlet is closed and the outlet is open. When the water distribution switch is opened to introduce water into the storage tank, the first gravity ball inside the tank moves upward under water pressure, opening the inlet. Simultaneously, the second gravity ball moves downward to block the outlet, allowing cold water to enter the storage tank. After the cold water is drained, the water distribution switch is adjusted to another inlet pipe to introduce hot water into the mixing device. At the same time, because the water pressure at the inlet in the storage tank is lost, the first gravity ball moves downward to block the inlet, and the second gravity ball moves upward to open the outlet, allowing the cold water in the storage tank to automatically enter the mixing device and mix with the hot water. Therefore, the above automatic switching mechanism can automatically adjust the inlet or outlet of the storage tank according to the adjustment of the water distribution switch, realizing the temporary storage and automatic mixing of cold water, greatly improving the efficiency of water resource utilization, and is worthy of widespread promotion.

[0014] Preferably, both the first limiting member and the second limiting member adopt a hollow cylindrical structure, and the top of the first limiting member is provided with a limiting plate to prevent the first gravity ball from falling off.

[0015] With the above structural design, the cylindrical structure can play a guiding and limiting role, while the limiting plate at the top of the first limiting member can prevent the first gravity ball from being pushed out of the first limiting member under water pressure.

[0016] Preferably, the mixing device includes an outer shell and a built-in spray pipe. The upper end of the outer shell is connected to the outlet of the water storage tank, and the lower end is connected to the shower head through a pipe. The spray pipe is connected to the water inlet pipe.

[0017] Preferably, the nozzle has a guide pipe, one end of which is a connector connected to the water inlet pipe, and the other end is a conical pressure boosting nozzle, and a check valve is provided on the guide pipe.

[0018] Preferably, the water diversion switch includes a body, the upper end of which is connected to an external water pipe, and two bypass interfaces on the body that are respectively connected to the inlet pipe. A control valve is installed inside the body to control the switch of the bypass interfaces.

[0019] The above structural design enables rapid switching between cold and hot water. When using cold water, the inlet pipe is switched to directly enter the storage tank, and when using hot water, the inlet pipe is switched to enter the mixing device. The structure is simple and the operation is convenient.

[0020] Preferably, the water storage tank has a detachable cover at the top and an air vent on the side, and a hook assembly on the back that can be fixed to the wall.

[0021] The above structural design facilitates the disassembly and assembly of the water-saving device, making its placement more convenient.

[0022] To achieve the above objectives, this utility model also provides a shower system, including the aforementioned water-saving device, and further including a faucet and a shower head connected to an external cold water pipe and a hot water pipe. The outlet of the faucet is connected to the water distribution switch, and the shower head is connected to the mixing device through a connecting pipe.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. This utility model, through the water-saving device, can directly introduce cold water into the storage tank for temporary storage, and then introduce hot water into the mixing device through the water distribution switch to automatically mix with the cold water discharged from the storage tank, thereby avoiding the problem of wasting cold water in the early stage of showering, and saving one-tenth of the shower water consumption each time.

[0025] 2. The automatic switch mechanism installed in the water storage tank of this utility model can be automatically linked with the water distribution switch to realize the automatic opening and closing of the water inlet or outlet in the water storage tank, thereby realizing the automatic mixing of cold water and hot water and further improving the water-saving effect.

[0026] 3. The mixing device of this invention is based on Bernoulli's principle. Within the mixing device, the water flow rate at the nozzle is fast and the pressure is low, while the incoming cold water flows slowly and has a high pressure. Therefore, the water at the high-pressure area is naturally drawn to the low-pressure area, thereby improving mixing efficiency. Compared to mixing solely through gravity, this mixing device significantly improves mixing efficiency. Attached Figure Description

[0035] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0036] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] Please see Figures 1 to 6 A water-saving device, used in conjunction with a shower system, is installed between a faucet 6 and a shower head 7. The device includes a water distribution switch 1 and a water storage tank 2. A mixing device 3 is installed on the water storage tank 2 for mixing cold and hot water. The water distribution switch 1 is connected to both the water storage tank 2 and the mixing device 3 via an inlet pipe 4. An automatic switching mechanism 5 is installed inside the water storage tank 2 to control the inlet and outlet of water. Therefore, by incorporating this water-saving device, cold water can be introduced into the water storage tank 2 before showering, and then the cold water in the tank 2 can be mixed with hot water in the mixing device 3 before use, avoiding the waste of cold water in the early stages of showering.

[0038] The specific structure is as follows:

[0039] The inlet 2a of the water storage tank 2 is connected to the inlet pipe 4, and the outlet 2b of the water storage tank 2 is connected to the mixing device 3. In this embodiment, there are two inlet pipes 4, which are respectively connected to the water distribution switch 1 and switched by the water distribution switch 1. One water distribution pipe 4 is connected to the water storage tank 2, and the other is connected to the mixing device 3.

[0040] Please continue reading. Figure 2Furthermore, the automatic switching mechanism 5 includes a slide rod 5a installed on the inner wall of the water storage tank 2, a connecting rope 5b movably mounted on the slide rod 5a, and a limiting groove 5g in the middle of the slide rod 5a. A first gravity ball 5c and a second gravity ball 5d are respectively connected to both ends of the connecting rope 5b. A first limiting member 5e and a second limiting member 5f are respectively provided at the water inlet 2a and water outlet 2b of the water storage tank 2. The first gravity ball 5c and the second gravity ball 5d are respectively disposed within the first limiting member 5e and the second limiting member 5f to block the water inlet 2a or the water outlet 2b. Both the first limiting member 5e and the second limiting member 5f adopt a hollow cylindrical structure, and the top of the first limiting member 5e is provided with a limiting plate 51e to prevent the first gravity ball 5c from detaching.

[0041] In this embodiment, the weight of the first gravity ball 5c is greater than the weight of the second gravity ball 5d. Therefore, in the initial position, the inlet 2a is closed and the outlet 2b is open.

[0042] Please see Figure 4 and Figure 5 The mixing device 3 includes an outer shell 3a and a built-in nozzle 3b. The upper end of the outer shell 3a is connected to the outlet 2b of the water storage tank 2, and the lower end is connected to the shower head via a pipe. The nozzle 3b is connected to the inlet pipe 4. The nozzle 3b has a guide pipe 31b, one end of which is a connector 32b connected to the inlet pipe 4, and the other end is a conical pressure-boosting nozzle 33b. A check valve 34b is installed on the guide pipe 31b. When the cold water in the water storage tank 2 is used up, the pressure at the top of the mixing device 3 decreases. By installing the check valve 34b in the mixing device 3, the water sprayed from the nozzle 3b can be prevented from flowing back into the water storage tank 2. In this embodiment, the mixing device 3 is made using Bernoulli's principle, that is, in the mixing device 3, the water flow rate at the nozzle 3b is fast and the pressure is low, while the cold water entering the mixing device 3 has a slow flow rate and a high pressure. Therefore, the water at the high pressure point will naturally be drawn to the low pressure point, thereby improving the mixing efficiency. Compared to mixing by gravity alone, this mixing device 3 greatly improves mixing efficiency.

[0043] Please see Figure 6The water diversion switch 1 includes a body 1a, the upper end of which is connected to an external water pipe, i.e., to a faucet 6. The body 1a has two bypass ports 1b, each connected to the inlet pipe 4. A control valve 1c is installed inside the body 1a to control the opening and closing of the bypass ports 1b. The control valve 1c includes a hollow sphere 11c with its upper end inside the body 1a. The upper end of the sphere 11c is open, and one side has a through hole 12c that can rotate to connect with the inlet pipe 4. The lower end of the sphere 11c is connected to a rotating handle 13c, and the rotating handle 13c has an arrow pointing to the through hole 12c, facilitating the determination of whether the control valve 1c is open to the inlet pipe 4. The structure of this control valve 1c is prior art and will not be described in detail.

[0044] Furthermore, the water storage tank 2 is provided with a detachable tank cover 2c at the upper end, and an air vent 2d on the side. The back of the water storage tank 2 is provided with a hook assembly 2e that can be fixed to the wall.

[0045] This utility model also provides a shower system, including the water-saving device, and further including a faucet 6 and a shower head 7 connected to an external cold water pipe and a hot water pipe. The water outlet of the faucet 6 is connected to the water distribution switch 1, and the shower head 7 is connected to the mixing device 3 through a connecting pipe.

[0046] The working principle of this utility model is as follows:

[0047] The water-saving device's water distribution switch 1 is connected to the faucet 6, and the mixing device 3 is connected to the shower head 7. In the initial state, the weight of the first gravity ball 5c in the water storage tank 2 is greater than that of the second gravity ball 5d. Therefore, the water inlet 2a of the water storage tank 2 is closed, and the water outlet 2b is open.

[0048] In use, adjust the water distribution switch 1 to the left inlet pipe 4 and simultaneously turn on the faucet 6 to introduce the freshly flowing cold water into the storage tank 2. Due to the water pressure generated by the water flow in the inlet pipe 4, the first gravity ball 5c in the storage tank 2 moves upward and the second gravity ball 5d moves downward. At this time, the inlet 2a of the storage tank 2 opens and the outlet 2b closes, allowing cold water to temporarily enter and be stored in the storage tank 2. Based on experience, after the estimated cold water has been drained, adjust the water distribution switch 1 to the right inlet pipe 4, allowing hot water to enter the mixing device 3 through the inlet pipe 4. Simultaneously, due to the loss of water pressure at the inlet 2a in the storage tank 2, the first gravity ball 5c moves downward to block the inlet 2a, and the second gravity ball 5d moves upward, opening the outlet 2b. The cold water in the storage tank 2 automatically enters the mixing device 3 to mix with the hot water entering through the inlet pipe 4 until the cold water in the storage tank 2 is used up. The mixing device 3 is manufactured using Bernoulli's principle, which improves the mixing efficiency of hot and cold water entering the mixing device 3. Therefore, the automatic switching mechanism 5 of this invention can automatically adjust the inlet or outlet water in the water storage tank 2 according to the adjustment of the water distribution switch 1, realizing the temporary storage and automatic mixing of cold water.

[0049] This utility model's water-saving device can directly introduce cold water into the storage tank 2 for temporary storage, and then introduce hot water into the mixing device 3 through the water distribution switch 1 to automatically mix with the cold water discharged from the storage tank 2, thereby avoiding the problem of wasting cold water in the early stages of showering. Furthermore, this utility model's water-saving device has a simple structure and low cost, making it worthy of widespread promotion.

[0050] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
