Description

Technical Field

[0001] This utility model generally relates to the field of bathroom equipment technology, and more specifically, to a waterproof device for a reversing valve. Background Technology

[0002] Existing directional control valves typically use Y-rings to isolate and seal the water passage chamber from the motor. However, in practical applications, the sealing performance of the Y-ring is affected by factors such as installation accuracy, media characteristics, and operating pressure, posing a certain risk of leakage. If the Y-ring leaks, liquid may seep into the motor area, leading to motor rusting and seizing, especially when in contact with special liquids such as descaling solutions or chemical solutions, where the risk of corrosion increases significantly. Motor rusting and seizing will directly cause malfunction of the directional control valve, affecting the user experience.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0011] According to one embodiment of the present invention, the reversing valve is provided with an assembly cavity for accommodating the sealing isolation element and a water passage cavity for water passage, and a first drain port and / or a second drain port for communicating the assembly cavity with the outside. The first drain port corresponds to the position of the first sealing part, and the second drain port corresponds to the position of the second sealing part.

[0012] According to one embodiment of the present invention, the sealing isolation member is at least a first sealing part, and a first water-blocking edge is provided on the surface of the first sealing part opposite to the valve core. The first water-blocking edge is provided corresponding to the first drain port, and the first water-blocking edge is used to guide water flow out from the corresponding first drain port.

[0013] According to one embodiment of the present invention, the sealing and isolating member includes a first sealing part and a second sealing part;

[0014] The first sealing part is sleeved on the connecting shaft, and the second sealing part is coaxially sleeved between the first sealing part and the driving member on the side of the first sealing part near the driving member, with the first sealing part and the second sealing part overlapping each other.

[0015] Alternatively, the first sealing part and the second sealing part are coaxially sleeved on the connecting shaft, and the second sealing part is provided between the side of the first sealing part near the water passage cavity and the water passage cavity, with the first sealing part and the second sealing part overlapping each other.

[0016] According to one embodiment of the present invention, a second water-blocking edge is provided on the first sealing part, and the second water-blocking edge is provided corresponding to the second drain outlet. The second water-blocking edge is used to guide water flow out from the correspondingly provided second drain outlet.

[0019] According to one embodiment of the present invention, the driving component is a motor, the connecting shaft is a motor output shaft, and the motor output shaft drives the first sealing part through the flat part while simultaneously driving the valve core to rotate and switch the water passage.

[0020] According to one embodiment of the present invention, the reversing valve is composed of a valve body and a valve cover.

When leakage occurs with the traditional Y-ring, the first and second sealing parts enhance the waterproof performance at the connection between the drive component and the reversing valve, isolating the leaking water from contact with the motor and preventing damage from the leaking liquid. Furthermore, the first water-blocking edge on the first sealing part guides the water flow out through the corresponding drain port on the first sealing part. As the water continues to flow towards the motor side, the second water-blocking edge on the first sealing part further guides the water out through the corresponding drain port on the second sealing part. Guiding the leaked water out through the drain port effectively prevents moisture from penetrating into the motor, fundamentally eliminating the problem of the motor rusting and jamming due to contact with liquid, preventing the reversing valve from malfunctioning due to motor failure, and significantly improving product reliability and user experience.

[0039] like Figures 1-3 As shown, this embodiment provides a waterproof device for a reversing valve 100, including: a drive member 200, which has a connecting shaft 210 connected to a valve core 130 inside the reversing valve 100; the drive member 200 is used to drive the valve core 130 to move; and a sealing isolation member, which is a first sealing part 300 disposed between the valve core 130 and the connecting shaft 210, and / or, the sealing isolation member is a second sealing part 400 disposed between the body 220 of the drive member 200 and the reversing valve 100. It can be understood that the drive member 200 can be a power output device such as a motor or cylinder, or a transmission component such as a worm gear or pulley. The valve core 130 of the reversing valve 100 switches the water outlet path under the drive of the drive member 200. The reversing valve 100 can be a ball valve, a rotary valve, etc. In this embodiment, the driving component 200 is a motor, and the connecting shaft 210 is the motor output shaft. The motor output shaft drives the first sealing part 300 through a flat part, which in turn drives the valve core 130 to rotate and switch the water passage. The reversing valve 100 is provided with screw holes, and the motor is locked to the reversing valve 100 on both sides by bolts. The beneficial effect is that the provision of the first sealing part 300 and the second sealing part 400 increases the waterproof performance at the connection between the driving component 200 and the reversing valve 100, preventing leakage from entering the motor and causing damage. In this embodiment, the sealing isolation component includes the first sealing part 300 and the second sealing part 400; the first sealing part 300 and the second sealing part 400 are separately provided, the first sealing part 300 is specifically a bushing, and the second sealing part 400 is specifically a sealing gasket.

[0040] In some other embodiments, the first sealing portion 300 and the second sealing portion 400 are integrally formed.

[0041] In some embodiments, such as Figures 1-5As shown, the reversing valve 100 is provided with an assembly cavity 160 for accommodating the sealing isolator and a water passage cavity 140 for water passage, and a first drain port 141 and / or a second drain port 142 for communicating the assembly cavity 160 with the outside. The first drain port 141 corresponds to the position of the first sealing part 300, and the second drain port 142 corresponds to the position of the second sealing part 400. It can be understood that in the complete state of the reversing valve 100, the assembly cavity 160 and the chamber where the valve core 130 of the reversing valve 100 is located, i.e., the water passage cavity 140, are isolated from each other. The arrangement of the water passage cavity 140 and the assembly cavity 160 is conducive to a concealed design, making the overall device simpler and more aesthetically pleasing. At the same time, it protects the sealing isolator and reduces the probability of external damage. The first drain port 141 and / or the second drain port 142 further play a cooperating role, draining the leakage blocked by the sealing isolator, avoiding liquid accumulation, ensuring waterproof effect, and achieving double protection. The first drain outlet 141 is positioned in a manner that corresponds to the first sealing part 300, meaning that the first drain outlet 141 is positioned close to the first sealing part 300, so that leaked liquid can be discharged from the first drain outlet 141 in a timely manner after being blocked by the first sealing part 300.

[0042] In some embodiments, such as Figures 2-5 As shown, the sealing isolation component includes a first sealing part 300. A first water-retaining edge 310 is provided on the surface of the first sealing part 300 opposite to the valve core 130. The first water-retaining edge 310 is correspondingly provided with a first drain port 141 and is used to guide water flow out from the corresponding first drain port 141. It can be understood that the first water-retaining edge 310 can play a guiding role, so that the leakage blocked by the first sealing part 300 is directed out from the position of the first water-retaining edge 310, and in conjunction with the first drain port 141 located close to it, the leakage is discharged more quickly.

[0043] In some embodiments, such as Figures 2-5 As shown, a second water-retaining edge 320 is provided on the first sealing part 300, and the second water-retaining edge 320 is correspondingly provided with the second drain outlet 142. It can be understood that the first sealing part 300 has a certain length. When the water volume is too large and overflows the first water-retaining edge 310, the second water-retaining edge 320 can play a secondary blocking role, guiding the leaking liquid to the second drain outlet 142, which is closer to the second water-retaining edge 320, for discharge. In this embodiment, the outer diameter of the second water-retaining edge 320 is larger than the outer diameter of the first water-retaining edge 310, allowing the second water-retaining edge 320 to intercept a larger volume of water.

[0044] In some embodiments, the sealing isolation member includes a first sealing portion 300 and a second sealing portion 400; the first sealing portion 300 is sleeved on the connecting shaft 210, and the second sealing portion 400 is coaxially sleeved between the first sealing portion 300 and the driving member 200, with the first sealing portion 300 and the second sealing portion 400 overlapping each other; or, the first sealing portion 300 and the second sealing portion 400 are coaxially sleeved on the connecting shaft 210, and the second sealing portion 400 is disposed between the first sealing portion 300 and the water passage cavity 140, with the first sealing portion 300 and the second sealing portion 400 overlapping each other. In this embodiment, the first sealing portion 300 is sleeved on the connecting shaft 210, i.e., the output shaft of the motor, and the second sealing portion 400 is coaxially sleeved between the first sealing portion 300 and the driving member 200, with the first sealing portion 300 and the second sealing portion 400 overlapping each other.

[0045] In some embodiments, such as Figure 2 and Figure 5 As shown, the first drain port 141 and the second drain port 142 are sequentially arranged along the corresponding sleeve positions of the first sealing part 300 and the second sealing part 400. The arrangement of the first drain port 141 and the second drain port 142 serves as a gradient drainage function.

[0046] In some embodiments, such as Figure 6 As shown, the reversing valve 100 has a mounting groove 150 for a second sealing part 400. The mounting groove 150 has a drain channel 151, which communicates with the second drain port 142. In this embodiment, the second sealing part 400 is approximately σ-shaped, that is, the ring-shaped body has a protruding tail, so that the second sealing part 400 will not easily rotate after being embedded in the mounting groove 150. The second sealing part 400 just covers the drain channel 151.

[0047] In some embodiments, such as Figure 3 and Figure 7 As shown, the valve core 130 includes a core body 131, which has a shaft groove 1311 for connecting the connecting shaft 210. A first sealing part 300 is inserted into the shaft groove 1311, and a limiting rib 330 for circumferential positioning is provided between the first sealing part 300 and the shaft groove 1311. In this embodiment, during assembly, the connecting shaft 210 of the drive member 200 passes through the second sealing part 400 and the first sealing part 300 in sequence, and the first sealing part 300 is fitted into the shaft groove 1311 of the core body 131.

[0048] In some embodiments, such as Figures 3-7As shown, the reversing valve 100 consists of a valve body 110 and a valve cover 120. The valve body 110 has an inlet, and the valve cover 120 has several outlets. A fixed valve plate 134 is fixed to the valve cover 120. The valve core 130 includes a Y-ring 132, a core 131, a moving valve plate 133, and a fixed valve plate 134 connected in sequence. The motor output shaft drives the moving valve plate 133 to rotate to switch the water passage. It can be understood that the Y-ring 132 is located between the valve body 110 and the core 131 of the reversing valve 100. The Y-ring 132 divides the valve body 110 into an assembly cavity 160 and a water passage cavity 140. The side of the Y-ring 132 facing the valve cover 120 is the water passage cavity 140, and the side of the Y-ring 132 facing the drive component is the assembly cavity 160, sealing the chamber of the valve body 110 where the core 131 is located. When the Y-ring 132 leaks, the water first seeps into the first sealing part 300. Due to the action of the first water-blocking edge 310 of the first sealing part 300, the water will first flow out from the first drain port 141 on the valve body 110, thus preventing water from flowing onto the motor and causing rust. When the leakage of the Y-ring 132 is large, if the first drain port 141 cannot drain the water in time, the water may continue to spread. However, under the action of the second water-blocking edge 320 of the first sealing part 300 and the second sealing part 400, the water can only be discharged from the second drain channel 151 on the valve body 110 through the second drain port 142. Due to the action of the second sealing part 400 and the first sealing part 300, the water will not come into contact with the motor, thereby improving the service life of the motor and preventing the toilet seat from malfunctioning due to motor rust and jamming, which would affect the user experience.
