[0027] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0028] Please refer to the following: Figures 1 to 3 This utility model discloses a water purification device, which includes an instant heating pipe 20, a faucet 30, and a solenoid valve structure 10. The solenoid valve structure 10 of this solution includes a solenoid valve bracket 1, a connecting pipe assembly 2, a first solenoid valve 3, and a second solenoid valve 4. The first solenoid valve 3 and the second solenoid valve 4 are fixedly installed on the solenoid valve bracket 1. The first connecting port 211 of the connecting pipe assembly 2 is used to connect to the outlet end of the instant heating pipe 20. The first inlet 31 of the first solenoid valve 3 is connected to the second connecting port 221 of the connecting pipe assembly 2. The first outlet 32 ​​of the first solenoid valve 3 is connected to the inlet end of the instant heating pipe 20. The second inlet 41 of the second solenoid valve 4 is connected to the third connecting port 222 of the connecting pipe assembly 2. The second outlet 42 of the second solenoid valve 4 is used to connect to the faucet 30. The first solenoid valve 3 and the second solenoid valve 4 are not opened at the same time. With this design, when a user needs hot water, the water heated by the instant heating pipe 20 enters the connecting pipe assembly 2 through the first connection port 211. During the heating process of the instant heating pipe 20, the first solenoid valve 3 opens and the second solenoid valve 4 closes. Hot water that is too cold and does not meet the user's drinking needs is discharged back to the instant heating pipe 20 through the first solenoid valve 3 for reheating. When the instant heating pipe 20 heats the water to meet the user's drinking needs, the first solenoid valve 3 closes and the second solenoid valve 4 opens. The hot water is then discharged to the faucet 30 through the second solenoid valve 4 for the user to drink, thereby improving the user's experience.

[0029] In some embodiments, the solenoid valve bracket 1 is a long strip bracket, with the first solenoid valve 3 and the second solenoid valve 4 respectively installed at both ends along the length of the solenoid valve bracket 1. The connecting pipe assembly 2 includes a first connecting pipe 21 and a second connecting pipe 22. The second connecting pipe 22 is connected to the first connecting pipe 21 and located between the first solenoid valve 3 and the second solenoid valve 4. A first connection port 211 is provided on the first connecting pipe 21, and a second connection port 221 and a third connection port 222 are provided on the second connecting pipe 22. This design avoids interference between the connecting pipe assembly 2 and the connections of the first solenoid valve 3, the second solenoid valve 4, and the instant heating pipe 20. Furthermore, it allows for a more complex overall solenoid valve structure 10.

[0030] Furthermore, the first connecting pipe 21 and the second connecting pipe 22 are arranged in parallel so that the axis of the second connecting port 221 and the axis of the third connecting port 222 are both parallel to the axis of the first connecting port 211. This design allows for a more compact connection structure between the first solenoid valve 3, the second solenoid valve 4, the first connecting pipe 21, and the second connecting pipe 22, thereby making the entire solenoid valve structure 10 more compact.

[0031] In some embodiments, in order to connect the second connecting pipe 22 and the first connecting pipe 21, the first connecting pipe 21 is provided with a first pair of sockets 212, and the second connecting pipe 22 is provided with a second pair of sockets 223. The second pair of sockets 223 are inserted into the first pair of sockets 212 so that the second connecting pipe 22 is connected to the first connecting pipe 21.

[0032] Specifically, since the second connecting pipe 22 and the first connecting pipe 21 are arranged in parallel, the first pair of sockets 212 are located on the side of the first connecting pipe 21, and the second pair of sockets 223 are located on the side of the second connecting pipe 22, so that the second connecting pipe 22 and the first connecting pipe 212 can be parallel after the second pair of sockets 223 and the first pair of sockets 212 are connected.

[0033] Furthermore, considering that gaps may easily exist between the first pair of sockets 212 and the second pair of sockets 223, resulting in water leakage, the solenoid valve structure 10 also includes a sealing ring. The first pair of sockets 212 and the second pair of sockets 223 are sealed by the sealing ring, thereby improving the sealing performance between the first solenoid valve 3 and the second solenoid valve 4.

[0034] In some embodiments, the solenoid valve structure 10 further includes an NTC5, which is connected to the fourth connection port 213 of the connecting pipe assembly 2. The NTC5 is used to detect the water temperature entering the connecting pipe assembly 2 from the first connection port 211. With this design, the water temperature entering the connecting pipe assembly 2 can be monitored by the NTC5. When the water temperature is detected to be too low and does not meet the user's drinking needs, the first solenoid valve 3 is opened and the second solenoid valve 4 is closed; when the water temperature is detected to meet the user's drinking needs, the first solenoid valve 3 is opened and the second solenoid valve 4 is closed.

[0035] Furthermore, the axis of the fourth connection port 213 is parallel to the axis of the first connection port 211. This design makes the entire structure more compact.

[0036] In some embodiments, in order to enable the first solenoid valve 3 and the second solenoid valve 4 to be installed on the solenoid valve bracket 1, the solenoid valve bracket 1 is provided with a first mounting groove 11 and a second mounting groove 12. The first solenoid valve 3 is inserted and installed in the first mounting groove 11, and the second solenoid valve 4 is inserted and installed in the second mounting groove 12.

[0037] Furthermore, in order to fix the first solenoid valve 3 and the second solenoid valve 4 on the solenoid valve bracket 1, the solenoid valve bracket 1 is provided with a first mounting hole 13 and a second mounting hole 14, the first solenoid valve 3 is provided with a first connecting ear 33 having a third mounting hole 34, and the second solenoid valve 4 is provided with a second connecting ear 43 having a fourth mounting hole 44. The first mounting hole 13 and the third mounting hole 34 are connected by a first fastener, and the second mounting hole 14 and the fourth mounting hole 44 are connected by a fourth fastener.

[0038] The water purification device provided by this utility model includes a solenoid valve structure 10 comprising a solenoid valve bracket 1, a connecting pipe assembly 2, a first solenoid valve 3, and a second solenoid valve 4. The first solenoid valve 3 and the second solenoid valve 4 are fixedly installed on the solenoid valve bracket 1. The first connection port 211 of the connecting pipe assembly 2 is used to connect to the outlet end of the instant heating pipe 20. The first inlet port 31 of the first solenoid valve 3 is connected to the second connection port 221 of the connecting pipe assembly 2. The first outlet port 32 of the first solenoid valve 3 is connected to the inlet end of the instant heating pipe 20. The second inlet port 41 of the second solenoid valve 4 is connected to the third connection port 222 of the connecting pipe assembly 2. The second outlet port 42 of the second solenoid valve 4 is used to connect to a faucet 30. The first solenoid valve 3 and the second solenoid valve 4 are not opened simultaneously. With this design, when a user needs hot water, the water heated by the instant heating pipe 20 enters the connecting pipe assembly 2 through the first connection port 211. During the heating process of the instant heating pipe 20, the first solenoid valve 3 opens and the second solenoid valve 4 closes. Hot water that is too cold and does not meet the user's drinking needs is discharged back to the instant heating pipe 20 through the first solenoid valve 3 for reheating. When the instant heating pipe 20 heats the water to meet the user's drinking needs, the first solenoid valve 3 closes and the second solenoid valve 4 opens. The hot water is then discharged to the faucet 30 through the second solenoid valve 4 for the user to drink, thereby improving the user's experience.
