Description

Technical Field

[0001] The utility model belongs to the technical field of showers, and particularly relates to a cold water pre-drain shower structure. Background Art

[0002] With the continuous improvement of people's living standards, more and more families and hotels use showers. A shower is a device that sprays a mixture of cold water and hot water in a certain proportion. It is an essential device for every household's shower. Due to the limitation of the shower channel structure, there is usually a certain distance between the hot water inlet channel from the hot water source to the shower device. After the shower ends, a part of the water will remain inside the hot water inlet channel. If not used for a long time, the hot water in the channel will cool down, that is, it will turn from hot water to cold water and remain inside the channel. Next time when taking a shower, the cooled stored water needs to be drained before hot water can flow out. Therefore, when taking a shower next time, it is necessary to drain the cold water first, and one also needs to use the body to test the water temperature during the bath. Only when it reaches a certain temperature can one take a shower, which not only wastes water resources but also wastes time. In winter, being splashed by the residual cold water in the shower channel is likely to cause a cold, seriously affecting the user experience. In addition, the traditional shower structure also has the following problems:

[0003] 1. The traditional shower structure is equipped with an electric control device. When the electric control device fails, the entire shower head fails, and it is very difficult to repair and replace, bringing difficulties to the shower.

[0004] 2. Most of the traditional shower structures adopt the traditional mechanical valve core control method. This method cannot quickly and accurately adjust to the desired flow rate and temperature. When using it, one needs to adjust the device while perceiving the changes in flow rate and temperature, and repeat the above operations to achieve the desired effect. The adjustment process is cumbersome and time-consuming.

[0005] 3. Most of the traditional shower heads adopt electronic touch control switches. In actual use, the touch buttons are very easy to be accidentally touched, wasting water resources. At the same time, when taking a bath, the water droplets on the shower head or the ceiling spray splash onto the touch buttons, which is also very easy to trigger the touch buttons, resulting in misoperation of the electric shower.

[0028] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present utility model.

[0029] As Figures 1-8 shown, a pre-drain cold water shower structure of the present utility model is installed on one side of the shower valve body. The water inside the pre-drain cold water structure is the mixed water after mixing cold water and hot water. The pre-drain cold water shower structure includes a main control panel 2 and a pre-drain device 1, a MUCA integration group 3, a pre-drain switch 4, a flow regulation module 5 and a temperature regulation module 6 arranged on the main control panel 2. The pre-drain device 1 includes a functional channel 14 and a connection part 11, a solenoid valve 7 and a POM quick-opening valve core 13 which are cooperatively connected with the functional channel 14. The main water path is the water flow channel of the functional channel 14. A POM quick-opening valve core 13 is installed on one side of the functional channel 14, and a solenoid valve 7 is installed at the other end. A connection part 11 is arranged between the two. At the same time, the connection part 11 is provided with a pre-drain hole 1103. When the solenoid valve 7 on the functional channel 14 fails, the POM quick-opening valve core 13 can be controlled to quickly disconnect the main pipeline water path to avoid property losses to users.

[0030] The functional channel (14) is the main water flow channel, including the first chamber 1401 and the third chamber 1403 on both sides and the second chamber 1402 in the middle. An electromagnetic valve 7 is installed on the upper part of the first chamber 1401 and fixed through four bolt holes on the functional channel 14. A POM quick-opening valve core 13 is installed on the third chamber 1403 and fixed by screwing with the threads inside the functional channel 14 and the threads on the POM quick-opening valve core 13. A connecting part 11 is installed on the second chamber 1402, and the connecting part 11 is provided with a telescopic rod 1106, and the telescopic rod 1106 is installed inside the second chamber 1402.

[0031] An external DC waterproof wire 8 is provided on the electromagnetic valve 7 and connected to the MUCA integration group 3, which can control the on-off of the water flow. A rotary valve stem is provided on the POM quick-opening valve core 13, which can control the on-off of the water flow. The connecting part 11 is located in the middle of the functional channel 14 and is also the main water outlet channel for pre-discharging cold water.

[0032] In order to achieve the purpose of pre-discharging cold water, a main control panel 2 is provided outside the functional channel 14. The main control panel 2 is an exterior part for the user to operate the entire pre-drainage structure. A temperature adjustment module 6 is provided on one side of the main control panel 2, and a paraffin constant temperature valve core is installed inside, which can sense the water temperature and freely control the outlet water temperature. At the same time, the temperature can be displayed on the digital display screen belonging to the MUCA integration group 3. A flow rate adjustment module 5 is provided on one side of the temperature adjustment module 6. A bottom-in and side-out valve core is installed inside the flow rate adjustment module 5, which can adjust the size of the water output.

[0033] In order to achieve the purpose of pre-discharging cold water, a pre-drain switch 4 is provided on the main control panel 2. The pre-drain switch 4 is a push-button type, so there is no need to worry about accidental touch. After the pre-drain switch 4 is activated, the residual cold water in the channel will enter the first water inlet 1407 through the functional channel 14, then pass through the bottom of the POM quick-opening valve core 13, enter the second water outlet 1406 from the side of the POM quick-opening valve core 13, and at the same time enter the second water inlet 1408, then enter the electromagnetic valve 7, enter the third water outlet 1404 of the functional channel 14 through the water outlet of the electromagnetic valve 7, and then pass through the internal chamber of the functional channel 14, and finally enter the main water outlet 1405.

[0034] After the cold water enters the main water outlet 1405, it passes through the connecting part 11. Further, the connecting part 11 is provided with a telescopic rod 1106. The inside of the telescopic rod 1106 is hollow, that is, the pre-drain hole 1103 can accommodate the water flow, and the water flow is discharged through the direction controller 9. This structure can discharge the residual cold water in the channel. When the user hears a beep from the MUCA integration group 3 or sees the display screen go out, the water in the channel is the required shower temperature we set, and direct showering can be done without extra operations, making the shower experience better.

[0035] During use, when the solenoid valve 7 fails or the power supply is insufficient to start, the POM quick-opening valve core 13 on the functional channel 14 can be closed to cut off the water inlet of the main pipeline. The double-waterway inlet automatic switching structure of the functional channel 14 has two waterways. The first waterway is that the POM quick-opening valve core 13 passes through the solenoid valve position and then through the main outlet 1405 to discharge water, which is a parallel waterway. The second waterway enters the functional channel 14 through the bottom of the water distribution valve button (not described in the figure), and then discharges water from the main outlet 1405, which is a series waterway. It realizes the free switching between series and parallel of the two waterways, can control the water output simultaneously, or cut off the water inlet of one way, saving space, greatly reducing costs, being more convenient for maintenance and replacement, and avoiding the failure of the entire shower structure due to the failure of the electric control device.

[0036] There are two flat gaskets 15 provided at the lower part of the functional channel 14. The two flat gaskets 15 are installed at the bottom of the functional channel 14. Further, a first groove 1411 and a second groove 1410 are provided at the bottom of the functional channel 14 to accommodate the two flat gaskets 15. After the flat gaskets 15 are installed, the positioning holes 1409 of the functional channel 14 can be locked on the valve body with four screws, which can not only ensure the fixation of the functional channel 14 but also play a sealing role, effectively preventing potential water leakage.

[0037] An O-ring 12 is provided at one end of the telescopic rod 1106 of the connecting part 11. The telescopic rod 1106 is installed inside the second cavity 1402 of the functional channel 14. Relying on the two O-rings 12 can ensure the non-leakage of the pre-drainage structure. Positioning grooves 1105 are provided on both sides of the end of the connecting part 11 device, and a positioning platform 1001 is provided on the edge of the positioning sleeve 10. The positioning platform 1001 can be directly buckled on the positioning grooves 1105 for fixation. The positioning platforms 1001 are distributed on both sides of the positioning sleeve 10, and at the same time, the positioning grooves 1105 are distributed on both sides of the connecting part 11.

[0038] A direction controller 9 is connected to the connecting part 11. The direction controller 9 is arranged between the positioning sleeve 10 and the connecting part 11 and is positioned by a positioning buckle 1101 provided at the front end of the connecting part 11. A limiting platform 1102 is also provided on the connecting part 11. The bottom of the direction controller 9 contacts the limiting platform 1102. The inside of the positioning sleeve 10 is an adjustment chamber 1002. The direction controller 9 can freely rotate a certain angle inside the adjustment chamber 1002, that is, the direction controller 9 can be manually toggled a certain angle inside the 1002 to adjust the water outlet direction, and can adjust an angle suitable for oneself for showering, thereby controlling the water outlet direction of the pre-drainage.

[0039] It should be noted that the MUCA integration group of the present application includes a power module, a temperature sensor, a digital display screen, a start switch, a PCB circuit board and some accessories.
