Technical Field
[0001] This utility model relates to a shower water pressure boosting device. Background Technology
[0002] Insufficient water pressure during showers is a common problem in daily life, especially in high-rise buildings or remote areas where the water supply pressure often fails to meet the needs of an ideal shower experience.

[0006] Furthermore, the shower water pressure boosting device of this utility model also includes a first pipe and a second pipe. One end of the first pipe is connected to a mixing valve and the other end is connected to a booster pump. The second pipe is installed at the water outlet.
[0007] Furthermore, the shower water pressure boosting device of this utility model also includes an indicator light, which is installed on the body and electrically connected to the controller.
[0008] Furthermore, the shower water pressure boosting device of this utility model also includes a magnetic wireless charging module and a wireless power bank. The magnetic wireless charging module is installed on the body. When the wireless power bank moves to fit against the magnetic wireless charging module, the wireless power bank and the magnetic wireless charging module are wirelessly connected.
[0009] Furthermore, the present invention provides a shower water pressure pressurization device, which also includes a frame, a pressure plate, and elastic elements. The frame is installed on the body corresponding to the magnetic wireless charging module, and has a frame opening at the top. The side away from the body is connected to the pressure plate through at least two elastic elements.
[0010] Furthermore, the frame includes a first side plate, a bottom plate, and a second side plate. The first side plate and the second side plate are erected at both ends of the bottom plate, and the tops of the first side plate and the second side plate are spaced apart to form a frame opening.
[0011] Furthermore, the elastic element includes a storage tube, a guide rod, and a spring. The storage tube is mounted on the frame. One end of the guide rod is connected to the pressure plate, and the other end is inserted into the storage tube through the spring. One end of the spring is connected to the storage tube, and the other end is connected to the pressure plate.
[0012] Furthermore, the touch screen displays battery level, water temperature, and water pressure, and includes a pressure adjustment button.
[0013] Furthermore, the shower water pressure boosting device of this utility model also includes a tap water pipe, a one-way valve, a housing, a retractable inner tank, a supporting water pipe, and a water supply pipe. The retractable inner tank is installed in a ventilated housing.

[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This utility model has the ability to generate electricity using the temperature difference of bath water and to store the generated electricity. Specifically, a thermoelectric generator is installed between cold and hot water pipes. The thermoelectric generator generates electricity using the temperature difference between the cold and hot water pipes. The generated electricity is stored in a battery, which can supply power to a booster pump. A pressure sensor monitors the bath water pressure. When the bath water pressure is lower than a set lower limit, the controller controls the booster pump to work, increasing the bath water pressure and improving bathing comfort.
[0017] 2. This invention uses a storage battery to power the booster pump, avoiding the need for the booster pump to be powered by mains electricity. This improves bathing safety and effectively prevents electric shock.
[0018] 3. This utility model enables water replenishment to achieve the water pressure required for bathing. Specifically, a retractable inner tank stores water, and a supporting water pipe connects to the retractable inner tank via perforated holes. When the external water supply is interrupted, water from the retractable inner tank enters the supporting water pipe through the perforated holes. The supporting water pipe then guides the water to the cold water pipe, increasing the water flow rate. The water then enters the mixing valve and is pressurized by the booster pump to achieve the required bathing water pressure. Attached Figure Description

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] like Figures 1 to 4 As shown, a shower water pressure boosting device includes a body 1, a mixing valve 2, a cold water pipe 16, a hot water pipe 17, thermoelectric generators 15, a booster pump 4, and a pressure sensor 6. The body 1 is equipped with a touch screen display 9, a controller 11, a battery 13, and a charging / discharging module 14. The touch screen display 9 and the battery 13 are electrically connected to the controller 11, and the charging / discharging module 14 is electrically connected to the battery. The cold water pipe 16 and the hot water pipe 17 are arranged in parallel at intervals and extend into the body 1. Within the body, they form multiple parallel intervals and bend before extending out of the body 1, and then connect to the mixing valve 2 respectively. Multiple thermoelectric generators 15 are installed at intervals between the cold water pipe 16 and the hot water pipe 17. One side of each thermoelectric generator 15 is attached to the cold water pipe 16, and the other side is attached to the hot water pipe 17. The booster pump 4 has an inlet and an outlet. The inlet is connected to the mixing valve 2, and the pressure sensor 6 is installed at the outlet. Both the booster pump 4 and the pressure sensor 6 are electrically connected to the controller 11. Among them, multiple thermoelectric generators 15 are electrically connected to the charging and discharging module 14.
[0028] The mixing valve includes a hot water inlet, a cold water inlet, and an outlet. The hot water inlet is connected to the hot water pipe, the cold water inlet is connected to the cold water pipe, the outlet is connected to the booster pump, and the booster pump is connected to the shower pipe.
[0029] It should be noted that the mixing valve is a commonly used shower mixing valve.
[0030] Understandably, the booster pump can operate at 24V. A battery can supply power to the booster pump. And 24V is considered a safe voltage.
[0031] The touchscreen display 9 shows the battery level, water temperature, and water pressure, and includes a pressure adjustment button. The battery level display allows users to easily determine the battery's charge level. The water temperature display shows the bath water temperature, and the water pressure display shows the bath water pressure. The pressure adjustment button on the touchscreen display 9 is touch-sensitive and allows users to adjust the required water pressure. The upper and lower limits of the bath water pressure can be set on the controller using the pressure adjustment button.
[0032] In some alternative embodiments, a connection structure for the booster pump is provided. A first pipe 3 and a second pipe 5 are added. One end of the first pipe 3 is connected to the mixing valve 2, and the other end is connected to the booster pump 4. The second pipe 5 is installed at the outlet end.
[0033] In some optional embodiments, an indicator light 8 is added to facilitate the monitoring of the pressurizing pump's operating status. The indicator light 8 is mounted on the body 1 and electrically connected to the controller 11.
[0034] When the booster pump 4 is working, indicator light 8 will show green. This indicates that the supply of hot and cold water pressure is lower than the set water pressure for showering, and the booster pump 4 will work to increase the shower water pressure.
[0035] The indicator light will turn red when the supply of hot or cold water pressure is equal to or higher than the set shower pressure. This indicates that the booster pump is not working.
[0036] In some optional embodiments, when the power generation due to the temperature difference of the bath water is insufficient, a magnetic wireless charging module 12 and a wireless power bank 10 are added. The magnetic wireless charging module 12 is installed on the body 1. When the wireless power bank 10 moves to fit against the magnetic wireless charging module 12, the wireless power bank 10 and the magnetic wireless charging module 12 are wirelessly connected.
[0037] When charging, the wireless power bank 10 is moved to the magnetic wireless charging module 12, and the magnetic wireless charging module 12 and the wireless power bank 10 are attracted to each other, so that the wireless power bank 10 and the magnetic wireless charging module 12 are in contact. The wireless power bank 10 supplies power to the magnetic wireless charging module 12, and the magnetic wireless charging module 12 charges the battery 13.
[0038] In some optional embodiments, to further secure the wireless power bank 10 and the magnetic wireless charging module 12, a frame 18, a pressure plate 19, and elastic elements 20 are added. The frame 18 is mounted on the body 1 corresponding to the magnetic wireless charging module 12, and has a frame opening 184 at the top. The side away from the body 1 is connected to the pressure plate 19 through at least two elastic elements 20.
[0039] When in use, the wireless power bank 10 is inserted into the frame 18 through the opening 184. When inserted, because the thickness of the wireless power bank 10 is greater than the distance between the pressure plate 19 and the surface of the body 1, the wireless power bank 10 pushes the pressure plate 19 to move outward. The pressure plate 19 pulls the elastic element 20 to deform outward. The elastic element has elastic potential energy, and the elastic element pulls the pressure plate 19 in the opposite direction. The pressure plate 19 then squeezes the wireless power bank 10 tightly against the magnetic wireless charging module 12. After releasing, the wireless power bank 10 will not fall off due to the interaction between the frame 18, the pressure plate 19 and the elastic element 20, and the wireless power bank 10 and the magnetic wireless charging module 12 remain in contact.
[0040] In some alternative embodiments, one structure of the framework is provided. For example... Figure 2 As shown, the frame 18 includes a first side plate 181, a bottom plate 182 and a second side plate 183. The first side plate 181 and the second side plate 183 are erected at both ends of the bottom plate 182. The tops of the first side plate 181 and the second side plate 183 are spaced apart to form a frame opening 184.
[0041] The base plate 182 can support the wireless power bank 10 and prevent the wireless power bank 10 from falling downwards.
[0042] The first side plate 181 and the second side plate 183 can prevent the wireless charging bank 10 from moving to the sides.
[0043] In some alternative embodiments, one structure of the elastic element is provided. The elastic element 20 includes a storage cylinder 201, a guide rod 203, and a spring 202. The storage cylinder 201 is mounted on the frame 18. One end of the guide rod 203 is connected to the pressure plate 19, and the other end passes through the spring 202 and is inserted into the storage cylinder 201. One end of the spring 202 is connected to the storage cylinder 201, and the other end is connected to the pressure plate 19.
[0044] The guide rod 203 can be movably stored inside the storage cylinder. That is, the guide rod can extend and retract relative to the storage cylinder. In addition, the guide rod 203 can also support the spring.
[0045] When the pressure plate moves outward relative to the frame, it causes the guide rod and spring to extend. When the spring extends, it undergoes elastic deformation and has elastic properties. The pressure plate is then pulled in the opposite direction by the spring force, which causes the pressure plate to squeeze the wireless charging bank 10 inserted into the frame.
[0046] According to the above embodiments, the working principle of this utility model is as follows:
[0047] When the mixing valve 2 is opened, cold water flows through the cold water pipe 16 and hot water flows through the hot water pipe 17. The multiple thermoelectric generators 15 located between the cold water pipe 16 and the hot water pipe 17 generate electricity by utilizing the temperature difference between the cold water and the hot water. The generated electricity is stored in the battery 13 through the charge and discharge module 14.
[0048] The water temperature monitored by temperature sensor 8 is transmitted to controller 11, which then displays the water temperature on touch screen 9, allowing the temperature of the water discharged from mixing valve 2 to be known in real time.
[0049] Pressure sensor 6 monitors the water pressure discharged from mixing valve 2 in real time. When the water pressure is lower than the set lower limit of the shower water pressure, controller 9 controls booster pump 4 to operate. Booster pump 4 is powered by battery 13. After starting, booster pump 4 increases the water pressure. When the water pressure reaches the set upper limit of the shower water pressure, controller controls booster pump to stop operating. This provides the required shower water pressure, improving shower comfort.
[0050] It should be noted that when the shower water pressure is often insufficient, a water pressure value can be set on the touch screen, and the controller will control the booster pump to constantly provide the set water pressure value.
[0051] This invention uses a storage battery to power the booster pump, which avoids powering the booster pump through the mains power supply and improves safety during use.
[0052] In some optional embodiments, a water replenishment structure is provided when the water supply network flow is insufficient, which includes a tap water pipe 25, a one-way valve 24, a housing 21, a retractable inner liner 22, a support water pipe 23, and a replenishment water pipe 26. The retractable inner liner 22 is installed inside the ventilated housing 21. The support water pipe 23 passes through the housing 21 and the retractable inner liner 22, and the connection between the support water pipe 23 and the retractable inner liner 22 is sealed. One end is connected to the tap water pipe 25, which is equipped with the one-way valve 24, and the other end is connected to one end of the replenishment water pipe 26. The other end of the replenishment water pipe 26 is connected to the cold water pipe 16. The support water pipe 23 has multiple permeable holes 231 distributed on the pipe wall inside the retractable inner liner 22.
[0053] The connection between the supporting water pipe 23 and the retractable inner liner 22 is a sealed connection, which can effectively prevent water leakage at the connection.
[0054] Multiple water-permeable holes 231 are distributed on the supporting water pipe 23. The supporting water pipe is connected to the inner space of the retractable inner liner through the multiple water-permeable holes. It can be understood that water in the supporting water pipe 23 enters the retractable inner liner 22 through the multiple water-permeable holes 231, and water in the retractable inner liner 22 can also enter the supporting water pipe through the water-permeable holes.
[0055] One type of expandable inner liner can be made of soft plastic. Specifically, the soft plastic is food-grade thermoplastic polyurethane elastomer (TPU). The expandable inner liner can freely expand and contract with changes in water volume, achieving dynamic volume changes.
[0056] It should be noted that the enclosure provides rigid support for the retractable inner liner while limiting its excessive expansion.
[0057] The one-way valve prevents water from flowing back and ensures that the water tank remains full.
[0058] To facilitate control of the cold water pipe's flow, a control valve 27 is installed. The control valve 27 is installed on the cold water pipe 16, with its outlet end near the connection point between the cold water pipe 16 and the water supply pipe 26. The control valve is used to control the flow of cold water into and out of the cold water pipe.
[0059] The surface of the housing 21 has ventilation holes 211. This facilitates the expansion and contraction of the retractable inner liner and significantly reduces the resistance during this process. Understandably, when the retractable inner liner expands, it forces air out of the housing through the ventilation holes 211. When the retractable inner liner contracts, the air inside the housing connects with the external atmospheric pressure through the ventilation holes; therefore, the contraction of the retractable inner liner does not create negative pressure inside the housing.
[0060] It should also be noted that both the cold water pipe and the tap water pipe are connected to the tap water network.
[0061] Work style:
[0062] Normal water storage: When the shower is off, the external water pressure pushes the water flow into the support water pipe. The water in the support water pipe enters the retractable inner tank through multiple water-permeable holes. The retractable inner tank expands to the limited volume of the cabinet 21. For example, the limited volume of the cabinet can be set to 10L.
[0063] Dynamic compensation: Triggering condition: When the shower is turned on and the external water supply flow rate Q_external < the user-set flow rate target Q (e.g., 6L / min): The pressure pump draws water, causing the outlet pressure of the cold water pipe 16 to drop, creating a pressure difference ΔP between the inside and outside of the retractable inner tank.
[0064] ΔP drives the inner liner to contract, and the water stored in the expandable inner liner enters the supporting water pipe through the water permeable hole, replenishing the flow rate Q compensation = Q target - Q external.
[0065] Compensation termination: When Q_external ≥ Q_target or the expandable inner liner is emptied, the expandable inner liner stops contracting.
[0066] Emergency Mode: In the event of an external water outage, i.e., a interruption of the municipal water supply, the user manually switches control valve 27. Water from the retractable inner tank flows through the permeable holes into the support water pipe, which then directs the water into the replenishment water pipe. The replenishment water pipe then supplies water to the cold water pipe, thus replenishing the cold water supply. This provides temporary water supply, such as a 10L water tank outputting at 6L / min for 1 minute and 40 seconds.
[0067] Application Examples:
[0068] Target flow rate Q target: 4~10L / min (user-defined), for example, user sets Q target = 8L / min.
[0069] When the water tank volume VV ≥ T×(Q_target - Q_external), and Q_external = 5L / min, V ≥ 15L (T = 5min).
[0070] Permeable hole diameter: 0.5~1mm, hole diameter 0.8mm, hole spacing 10mm.
[0071] It is understood that the hot water of this invention can be supplied by air source water heaters, solar water heaters, etc.
[0072] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
