The upper end of the slide bar 20 is slidably connected to the motor seat 11. The elastic sheet 26 is fixedly connected to the slide bar 20. The return spring 25 is sleeved on the slide bar 20 and one end of the return spring 25 is fixedly connected to the motor seat 11. The elastic sheet 26 is fixedly connected to the slide bar 20. The cross section of the first sealing plate 21 is an I-shaped, and the diameter of the first sealing plate 21 is the same as the diameter of the internal flow channel 124 of the three-way frame 12. The connecting plate 30 is fixedly connected to the end wall of the motor base 11, and the preload spring 29 is sleeved on the slide bar 20. One end of the preload spring 29 is fixedly connected to the end wall of the connecting plate 30, and the first sealing plate 21 is fixedly connected to the other end of the preload spring 29. The sealing ring 22 is sleeved on the first sealing plate 21, and the outer diameter surface of the sealing ring 22 is pressed against the inner wall of the internal flow channel 124. The second sealing plate 23 is fixedly connected to the lower end of the slide bar 20, and the conical sealing ring 28 is sleeved on the second sealing plate 23. The outer diameter surface of the conical sealing ring 28 is pressed against the side wall of the internal flow channel 124, and a part of the conical sealing ring 28 is inserted into the internal flow channel 124.

[0054] The motor base 11 and the three-way frame 12 are connected to each other through a clamping member, which includes a clamping block 14; a clamping groove 13 is provided at the lower end of the motor base 11, and the clamping groove 13 is an annular groove. A plurality of clamping blocks 14 are provided and fixedly connected to the top wall of the three-way frame 12 at equal intervals, and the clamping blocks 14 are respectively clamped in the clamping grooves 13. A groove 31 is provided on the clamping block 14, and a part of the lower end of the motor base 11 extends into the groove 31.

[0055] In order to seal, a sealing assembly is also provided, which includes: a first sealing ring 15, a second sealing ring 16, and a third sealing ring 17; the first sealing ring 15 is sleeved on the motor base 11, the second sealing ring 16 is sleeved on the upper end of the three-way frame 12, and the third sealing ring 17 is sleeved on the lower end of the three-way frame 12. The sealing ring 22, the conical sealing ring 28, the first sealing ring 15, the second sealing ring 16, and the third sealing ring 17 are all made of rubber and have elasticity.

[0056] Working or installation process:

[0057] Initial state:

[0058] The second sealing plate 23 is located in the internal flow channel 124 of the motor base 11 and the conical sealing ring 28 is pressed and sealed against the inner wall of the internal flow channel 124; the first sealing plate 21 is located above the internal flow channel 124 and the first sealing plate 21 is not in contact with the inner wall of the internal flow channel 124, and the return spring 25 is in a state of being free of force;

[0059] The water flows into the internal flow channel 124 from the second interface 122, and the water flows through the flow channel 27 on the guide plate 18. Due to the setting of the inclined surface 19, the resistance of the water flow is reduced, so that when the water flows through the guide plate 18, the noise of the water flow is reduced. The water flows out from the upper end of the internal flow channel 124 and flows out of the third interface 123 to the outside of the three-way skeleton 12.

[0060] The three-way motor is slid from the removal slot 24 into the top of the motor seat 11 and the output end of the three-way motor is aligned with the upper end of the slide bar 20. When the three-way motor is started, the output end of the three-way motor pushes the slide bar 20 to move downward, and the slide bar 20 drives the spring 26 to move downward. The spring 26 follows the slide bar 20 to move vertically downward and squeeze the return spring 25, so that the return spring 25 is in a compressed state. When the slide bar 20 moves downward, it drives the first sealing plate 21 and the sealing ring 22 to move downward. The first sealing plate 21 and the sealing ring 22 move downward and are inserted into the inner wall of the internal flow channel 124 of the three-way frame 12, so that the sealing ring 22 is in sealing contact with the inner wall of the internal flow channel 124.

[0061] When the three-way motor is started in the reverse direction, the output end of the three-way motor no longer pushes the upper end of the slide rod 20, the return spring 25 is no longer compressed, the return spring 25 releases its own elastic potential energy, and pushes the spring sheet 26 to move upward, the spring sheet 26 drives the slide rod 20 to move upward, and the slide rod 20 drives the first sealing plate 21 and the sealing ring 22 to move upward, so that the first sealing plate 21 and the sealing ring 22 are pulled out from the internal flow channel 124 of the three-way frame 12;

[0062] When the three-way motor needs to be replaced, the three-way motor is directly extracted slightly upwards and moved horizontally out from the removal slot 24 to avoid the three-way motor being unable to be directly removed from the top of the motor seat 11 due to the small space at the upper end of the motor seat 11 during actual use. By setting the removal slot 24 at the upper end of the motor seat 11, the three-way motor can be directly moved horizontally out from the removal slot 24.

[0063] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features are replaced with the technical features with similar functions disclosed in the embodiments of the present disclosure (but not limited to) and the technical solutions formed.
