A distribution valve with active shut-off function

Abstract

This utility model relates to a distribution valve with an active shut-off function, including a shower box housing, a distribution valve body, and a rotating block. The rotating block is provided at the output end of the distribution valve body. The shower box housing is provided with a hot and cold water mixing inlet and multiple hot and cold water outlets and isolation zones arranged in a ring around the hot and cold water mixing inlet. When no water outlet is being distributed, the rotating block is driven to rotate by the distribution valve body, so that the strip hole covers the hot and cold water mixing inlet and the isolation zone. With this configuration, even if the solenoid valves controlling the cold water channel and the hot water channel are damaged, water will not directly pass through the distribution valve and flow out from the distributed outlet.

[0002] Currently, most hot and cold water shower boxes on the market use solenoid valves to control the ratio of cold and hot water inlets. The solenoid valve controls the flow, and then a water circuit conveyor belt distribution valve determines which outlet to connect to. In this type of shower box, the water output is controlled by the solenoid valve, and the distribution valve is only used to distribute the outlet. There is a technical problem: when the solenoid valve is damaged, the distribution valve cannot stop the flow, and water will continue to flow out from the designated outlet. In view of this, this solution was developed. Utility Model Content

[0017] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0018] like Figures 1-9 As shown, this embodiment provides a distribution valve with an active shut-off function, including a shower box housing 1, an upper outer shell 2, a lower outer shell 3, a distribution valve body 4, and a rotating block 5.

[0019] The shower box housing 1 has a cold water channel 11, a hot water channel 12, a hot and cold water mixing channel 13, and four water outlet channels. Solenoid valves are installed at the outlets of the cold water channel 11 and the hot water channel 12. The solenoid valves are used to control the flow of cold and hot water. The water in the cold water channel 11 and the hot water channel 12 is controlled to enter the hot and cold water mixing channel 13. The shower box housing 1 has a hot and cold water mixing inlet 14, which is connected to the hot and cold water mixing channel 13. The shower box housing 1 has four hot and cold water outlets 15. The four hot and cold water mixing outlets are arranged in a ring along the hot and cold water mixing inlet 14. A partition area 16 is formed between any adjacent hot and cold water mixing outlets. Specifically, the shower box housing 1 has a closed-loop sealing groove 17 surrounding the four hot and cold water outlets 15. A special-shaped sealing ring is provided in the closed-loop sealing groove 17.

[0020] A temperature measuring hole is provided on the hot and cold water mixing channel 13, and a thermometer is installed in the temperature measuring hole.

[0021] A distribution valve body 4 and a rotating block 5 are provided above the hot and cold water mixing inlet 14, the four hot and cold water outlets 15, and the partition area 16. The rotating end of the distribution valve body 4 is connected to the rotating block 5. A strip-shaped hole 522 extending outward is formed in the middle of the lower surface of the rotating block 5. The strip-shaped hole 522 is connected to the hot and cold water mixing inlet 14. The rotation of the distribution valve body 4 controls the hot and cold water mixing inlet 14 to communicate with the four hot and cold water mixing outlets or the partition area 16 respectively. A pressure block 6 is also provided between the rotating block 5 and the upper surface of the shower box. The pressure block 6 is used to fit the area of ​​the shower box housing 1 with the hot and cold water mixing inlet 14, the hot and cold water outlets 15, and the partition area 16 and to press the irregular sealing ring. A first corresponding hole corresponding to the hot and cold water mixing inlet 14 is formed in the middle of the pressure block 6. Four second corresponding holes corresponding to the four hot and cold water mixing outlets are also provided around the pressure block 6.

[0022] The rotating block 5 includes an upper adapter block 51 and a lower drive block 52. The upper adapter block 51 is connected to the rotating end of the distribution valve. An insert block 513 is formed on the lower surface of the upper adapter block 51, and a notch 521 is formed on the upper surface of the lower drive block 52. The insert block 513 and the notch 521 are adapted to each other. A strip hole 522 is located on the lower surface of the lower drive block 52, and the notch 521 is located at the outer edge of the lower drive block 52. There are four notches 521, which are arranged in a ring at intervals along the axis of the lower drive block 52. The number of insert blocks 513 corresponds to the number of notches 521.

[0023] Preferably, the upper adapter block 51 includes a plug-in portion 511 and a connecting portion 512. The connecting portion 512 is located above the plug-in portion 511. The connecting portion 512 has a boss 5121. A connecting hole is formed in the middle of the boss 5121. The connecting hole is used to connect with the rotating end of the distribution valve body 4.

[0024] The distribution valve body 4 is located inside the upper outer shell 2, while the shower box housing 1 and the rotating block 5 are located inside the lower outer shell 3. Specifically, a mounting groove is formed on the lower surface of the upper outer shell 2, the adapter block is located in the mounting groove, a through hole is formed at the bottom of the mounting groove, a boss 5121 extends out of the through hole, and a sealed connection is formed between the boss 5121 and the mounting groove. A sealing groove is also formed at the bottom of the mounting groove, the through hole is located on the bottom wall of the sealing groove, and a limit ring 5122 is formed at the lower end of the boss 5121. The limit ring 5122 extends into the sealing groove, and a sealing ring is fitted on the outer circumference of the boss 5121 and located above the limit ring 5122. This configuration achieves electrical isolation between the electrical equipment (distribution valve and solenoid valve) and the shower box housing 1 (water passage area).

[0025] This solution features a rotating block 5 at the output end of the distribution valve body 4. The shower box housing 1 has a hot and cold water mixing inlet 14 and multiple hot and cold water outlets 15 and a partition area 16 arranged in a ring around the hot and cold water mixing inlet 14. When no outlet is being distributed, the rotating block 5 is driven to rotate by the distribution valve body 4, causing the strip hole 522 to cover the hot and cold water mixing inlet 14 and the partition area 16. With this configuration, even if the solenoid valves controlling the cold water channel 11 and the hot water channel 12 are damaged, water will not directly pass through the distribution valve and flow out from the distributed outlet.
