Description

Technical Field

[0001] This utility model relates to the field of shower device technology, and in particular to a shower device for collecting and reusing cold water from a shower head. Background Technology

[0002] After a typical shower setup is turned off, water may accumulate inside its internal chambers and pipes, which can easily drip from the overhead showerhead. Because the showerhead's nozzles are relatively small, it takes a considerable amount of time for the water inside the showerhead and pipes to drip completely. This can cause inconvenience and discomfort when users enter the bathroom space under the overhead showerhead during non-shower hours to clean or tidy up, resulting in water dripping onto their heads or clothes.

[0003] To address these issues, some shower systems have incorporated drainage devices that allow water to drain from the pipes through the spout or a dedicated drain outlet when the shower valve is closed. This automatic drainage when the shower is turned off effectively solves the problem of water accumulating inside the shower after it is shut down.

[0004] However, the water inside existing shower devices is usually completely drained, and once drained, it is simply wasted and cannot be reused. If the water could be collected and mixed with the cooled water with the newly added hot water the next time it is used, water resources could be utilized better and waste could be avoided. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this invention is to provide a shower device for collecting and reusing cold water from the shower head. This device can collect internal water and prevent dripping from the overhead shower head. When used again, the stored water can be mixed with newly added hot water, thus making better use of water resources and avoiding waste.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A shower device for collecting and reusing cold water from a shower head includes a shower body, an overhead shower head, and a hand shower head. The shower body is equipped with a water temperature regulating valve and a water outlet control valve. The water outlet control valve is used to control the on / off of the water supply path of the overhead shower head or the hand shower head. The shower body is provided with an upward-extending water storage pipe. The water storage pipe is provided with a water supply inner core pipe. The lower end of the water supply inner core pipe is sealed and connected to the warm water outlet of the shower body. The upper end of the water supply inner core pipe is connected to the input end of a Venturi spray pipe. The output end of the Venturi spray pipe is connected to the water supply pipe of the overhead shower head. The suction port of the Venturi spray pipe is connected to a water suction pipe. The water suction pipe is located in the water storage pipe and its lower end extends to the bottom of the water storage pipe. An overflow port is provided on the upper side of the water storage pipe.

[0008] Furthermore, the venturi nozzle is fitted into the upper end of the water storage pipe, and the suction port is connected to the upper end of the pumping pipe with its opening facing downwards.

[0009] Furthermore, the output end of the venturi nozzle is connected to the water supply pipe of the overhead shower head via a connecting pipe.

[0010] Furthermore, the output end is provided with a connecting thread that is sealed to the connecting pipe.

[0011] Furthermore, a sealing ring is provided between the lower end of the water supply inner core tube and the lower end of the water storage tube.

[0012] Furthermore, the top spray showerhead has a water-gathering groove at the bottom inner side of the water outlet panel. The top spray inlet pipe of the top spray showerhead extends from top to bottom, close to the bottom surface of the groove in the middle of the water-gathering groove, and together with the water supply pipe of the top spray showerhead, forms a return water siphon channel. This return water siphon channel is connected to the inner cavity of the water storage pipe through the suction port of the Venturi nozzle. When the water outlet control valve is closed, gravity is used to discharge the water accumulated in the inner cavity of the top spray showerhead and the upper part of the pipe into the water storage pipe for storage. When water is supplied to the top spray showerhead again through the water supply inner core pipe, the high-speed water flow enters the Venturi nozzle and then draws the water stored in the water storage pipe into the water supply pipe of the top spray showerhead for mixing and use.

[0013] Furthermore, the water storage volume inside the water storage pipe is greater than the sum of the internal cavity volume of the overhead shower head and the volume of the pipeline channel above the inlet.

[0014] Furthermore, the bottom surface of the shower body is provided with a third water outlet.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model is equipped with a Venturi spray pipe and a water storage pipe, which can collect the water accumulated inside the overhead shower head and prevent the overhead shower head from dripping. When used next time, the water accumulated in the water storage pipe can be mixed with the newly input hot water to avoid cold water stimulation during use, and can make better use of water resources and avoid waste.

[0017] 2. This utility model places the Venturi nozzle at the upper end of the water storage pipe, and then installs a water suction pipe in the water storage pipe connected to the suction port of the Venturi nozzle. The water path in the overhead shower head and the water supply pipe of the overhead shower head together form a return water siphon channel. This return water siphon channel is connected to the inner cavity of the water storage pipe through the suction port of the Venturi nozzle. When the water outlet control valve is closed, gravity is used to discharge the water accumulated in the inner cavity of the overhead shower head and the upper part of the pipe into the water storage pipe for storage. When water is supplied to the overhead shower head again through the water supply inner core pipe, the high-speed water flow enters the Venturi nozzle and then draws the water stored in the water storage pipe into the water supply pipe of the overhead shower head for mixing and use. This can effectively avoid the discomfort caused by the cold water remaining in the overhead shower head of the traditional structure spraying onto the user, and can also avoid the complete drainage of the water accumulated in the overhead shower head, thus making better use of water resources.

The shower body 1 is equipped with a water temperature regulating valve 4 and a water outlet control valve 5. The water outlet control valve 5 controls the flow of water to the overhead shower head 2 or the hand shower head 3. The shower body 1 has an upward-extending water storage pipe 6, and a water supply inner core pipe 7 is installed within the water storage pipe 6. The lower end of the water supply inner core pipe 7 is sealed and connected to the warm water outlet of the shower body 1, and the upper end of the water supply inner core pipe 7 is connected to the input of a Venturi spray pipe 8. The Venturi nozzle 8 is connected to the water supply pipe of the top spray shower 2 via the output end 82. The Venturi nozzle 8's suction port 83 is connected to a water suction pipe 9. The water suction pipe 9 is located in the water storage pipe 6 and its lower end extends to the bottom of the water storage pipe 6. The upper side of the water storage pipe 6 is provided with an overflow port 61. The water storage volume inside the water storage pipe 6 is greater than the sum of the internal cavity volume of the top spray shower 2 and the pipe channel volume above the suction port 83. If there is excess water inside the water storage pipe 6, the excess water will be drained from the overflow port 61. The Venturi nozzle 8 is fitted into the upper end of the water storage pipe 6, the suction port 83 is open downwards and connected to the upper end of the water pumping pipe 9, and a sealing ring 11 is provided between the lower end of the water supply inner core pipe 7 and the lower end of the water storage pipe 6; the Venturi nozzle 8 and the water pumping pipe 9 can be pre-set in the water storage pipe 6 as a component and then installed on the shower body 1 for easy installation and connection.

[0027] The output end 82 of the Venturi nozzle 8 is connected to the water supply pipe of the overhead shower head 2 via the connecting pipe 10.
