[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

A locking block 403 is movably connected to the installation block 4, and the installation block 4 is connected to the third connecting pipe 401 and the first connecting pipe 2 through the locking block 403. A bidirectional screw 801 and a guide rod 802 are provided inside the water storage tank 1 near the first connecting pipe 2. Two sealing plates 8 are connected to the bidirectional screw 801 and the guide rod 802. One end of the bidirectional screw 801 extends... A handwheel 803 is fixedly connected to the water storage tank 1. Here, the mounting block 4 is interconnected with the third connecting pipe 401 and the first connecting pipe 2. The bidirectional screw 801 is rotatably connected to the water storage tank 1 and threadedly connected to the sealing plate 8. The guide rod 802 is fixedly connected to the water storage tank 1 and slidably connected to the sealing plate 8. When the handwheel 803 is rotated clockwise, the handwheel 803 drives the connected bidirectional screw 801 to rotate clockwise, so that the sealing plates 8 on the bidirectional screw 801 move closer to each other under the limiting action of the guide rod 802, and the sealing plates 8 seal the water storage tank 1. When the handwheel 803 is rotated counterclockwise, the handwheel 803 drives the connected bidirectional screw 801 to rotate counterclockwise, so that the sealing plates 8 on the bidirectional screw 801 separate from each other under the limiting action of the guide rod 802, thereby releasing the sealing effect of the sealing plates 8 on the water storage tank 1.

[0024] like Figure 3As shown, the water storage tank 1 is fixedly connected with a partition 5 inside, the water storage tank 1 divides the internal space into hot water cavity and cold water cavity through the partition 5, the partition 5 is fixedly connected with heat insulation cotton 501 on the side facing the cold water cavity, here, the design of the partition 5 provides additional options for users, so that users can take cold and hot water according to their own needs, and the design of the heat insulation cotton 501 can block the heat flow from the hot water cavity inside the water storage tank 1 to the cold water cavity, which plays a role in heat preservation for the cold water cavity, effectively improving the flexibility and practicality of the device.

[0025] As shown in Figure 6 The second connecting pipe 3 is fixedly connected with a motor 6, the output shaft of the motor 6 extends into the second connecting pipe 3 and is connected with a baffle 601, here, the first connecting pipe 2 and the second connecting pipe 3 are in communication with the hot water cavity and the cold water cavity inside the water storage tank 1, the diversion end of the second connecting pipe 3 is provided with a baffle 601, the motor 6 is started, the motor 6 drives the output shaft to rotate, the output shaft of the motor 6 drives the connected baffle 601 to rotate, so that the baffle 601 no longer blocks the second connecting pipe 3, so that users can flexibly adjust the flow of cold and hot water according to their needs.

[0027] The device is used for heating water temperature, when the filter element 402 needs to be replaced, the device can be quickly replaced, first the hand wheel 803 needs to be rotated clockwise, the hand wheel 803 drives the connected bidirectional screw rod 801 to rotate clockwise, so that the sealing plates 8 on the bidirectional screw rod 801 move close to each other under the limiting action of the guide rod 802, the sealing plates 8 block the water storage tank 1, preventing the liquid in the water storage tank 1 from flowing back into the first connecting pipe 2, then the clamping block 403 is pulled out, so that the clamping block 403 exits the clamping groove formed in the mounting block 4, the first connecting pipe 2 and the third connecting pipe 401, thereby releasing the limiting action of the clamping block 403 on the mounting block 4, so that users can horizontally push the mounting block 4 to take it out, then replace the filter element 402 in the mounting block 4, after completion, the mounting block 4 is pushed again, so that the mounting block 4 returns to the initial position, then the clamping block 403 is inserted into the clamping groove of the mounting block 4 again by artificial means, so that the mounting block 4 is tightly connected with the first connecting pipe 2 and the third connecting pipe 401, the clamping block 403 fixes and limits the mounting block 4, then the hand wheel 803 is rotated counterclockwise, the hand wheel 803 drives the connected bidirectional screw rod 801 to rotate counterclockwise, so that the sealing plates 8 on the bidirectional screw rod 801 move away from each other under the limiting action of the guide rod 802, thereby releasing the blocking action of the sealing plates 8 on the water storage tank 1, so that the device enters standby state, thus completing the replacement work of the filter element 402 of the device.
