[0040] First embodiment Please refer to Figure 1 and Figure 2 This embodiment provides a water discharge device 100 of a manifold, including a connecting unit 110 and a water discharge unit 120, wherein the connecting unit 110 is used to connect to the manifold.

[0041] Please refer to Figure 3 The connecting unit 110 includes a connecting head body 111, a valve cover 112, a core rod 113 and a first driving member 114. The valve cover 112 is connected to one end of the connecting head body 111, and a drain port 1121 is provided at the end of the valve cover 112 away from the connecting head body 111. The valve cover 112 and the connecting head body 111 are connected to form a whole having an inner cavity, and the core rod 113 is accommodated in the inner cavity. The first driving member 114 controls the core rod 113 to move in the inner cavity so that the core rod 113 blocks the drain port 1121.

[0042] Please refer to Figure 4In this embodiment, the outer surface of the connector body 111 is used for connecting to one end of the manifold, and a threaded area 1118, a sealing area and a limiting area 1119 are sequentially arranged along the direction close to the valve cover 112; the connector body 111 is threadedly connected to the manifold through the threaded area 1118, and a sealing gasket 150 is arranged in the sealing area to prevent water leakage at the connection between the drain device and the manifold; the limiting area 1119 is a limiting protrusion, so that when the connector body 111 is connected to the manifold, it is sealed and connected through the threaded area 1118 and the sealing area, and is limited at the limiting area 1119.

[0043] In this embodiment, the first driving member 114 is an elastic member, specifically a spring, which is sleeved on the surface of the core rod 113 and drives the core rod 113 to move in the inner cavity through elastic force, so that the core rod 113 blocks the drain port 1121. By designing the connection unit 110 in the initial state, the drain port 1121 is in a blocked state, which is conducive to cooperating with the drain unit 120 to drain water, and at the same time preventing the water in the manifold from flowing out at will.

[0044] Please refer to Figure 5 The drainage unit 120 includes a drainage connector 121 and a drainage pipe 122, the drainage connector 121 and the drainage pipe 122 are sealed and connected, and one end of the drainage connector 121 away from the drainage pipe 122 is cooperatively connected with the valve cover 112; a second driving member 123 is arranged inside the drainage connector 121, and the second driving member 123 drives the core rod 113 to move in the inner cavity so that the core rod 113 opens the drainage port 1121.

[0045] In this embodiment, the second driving member 123 is a protrusion extending toward the valve cover 112, and the diameter of the second driving member 123 is smaller than the diameter of the drain port 1121; when the drain connection member 121 is connected to the valve cover 112, the second driving member 123 pushes the core rod 113 to open the drain port 1121, thereby ensuring the stability and controllability of the drain process.

[0046] Please refer to Figure 4 In this embodiment, the connector body 111 includes a flange 1111, a first wall 1112 and a second wall 1113. The second wall 1113 is sleeved in the first wall 1112 and spaced apart from the first wall 1112. The first wall 1112 and the second wall 1113 are connected by the flange 1111 on the side away from the drainage unit 120.

[0047] Please refer to Figure 6A drainage cavity 1114 is formed between the first wall 1112 and the second wall 1113, and a first drainage hole 1115 is provided in the area of ​​the flange 1111 corresponding to the drainage cavity 1114; the inner cavity surrounded by the second wall 1113 is a water-isolating cavity 1116, and the water-isolating cavity 1116 accommodates a core rod 113 and a first driving member 114. The core rod 113 is provided with a first diameter section 1131 and a second diameter section 1132 in sequence along the direction close to the drainage unit 120, and the diameter of the first diameter section 1131 is smaller than the diameter of the second diameter section 1132. The first driving member 114 is sleeved in the first diameter section 1131 and accommodated in the water-isolating cavity 1116, and the second diameter section 1132 blocks the end of the second wall 1113 away from the flange 1111.

[0048] When water needs to be drained, the water in the manifold flows from the first drain hole 1115 on the flange 1111 to the drain chamber 1114. Due to the isolation effect of the second wall 1113, the first diameter section 1131 of the core rod and the first driving member 114 will not be impacted by water in the water-isolating chamber 1116, which can effectively ensure the service life of the first driving member 114, that is, the spring, and avoid the spring from being impacted by water flow and failing after long-term water drainage.

[0049] In addition, the second diameter section 1132 blocks one end of the second wall 1113 away from the flange 1111, so that when the core rod 113 moves in the inner cavity, the contact between the second diameter section 1132 and the second wall 1113 can provide a guiding effect to prevent the core rod 113 from moving out of position in the inner cavity.

[0050] In this embodiment, in order to further ensure the moving direction of the core rod 113, an inner hole 1117 is formed on the flange 1111, and the first diameter section 1131 passes through and blocks the inner hole 1117, and can selectively move in the inner hole 1117. The inner hole 1117 of the flange 1111 cooperates with the first diameter section 1131 of the core rod 113, so that the movement process of the core rod can be further guided to prevent the core rod 113 from moving out of position in the inner cavity.

[0051] In this embodiment, in order to prevent water from entering the water-isolating chamber 1116 and affecting the service life of the first driving member 114 when water leaks, a groove for accommodating the sealing member 140 is opened at the inner hole 1117, and the sealing member 140 is arranged in the groove between the inner hole 1117 and the first diameter section 1131.

[0052] In this embodiment, in order to ensure the stable connection of the spring, a positioning groove 1134 is provided at the connection between the second diameter section 1132 and the first diameter section 1131. One end of the elastic member is fixed in the positioning groove 1134, and the other end thereof extends toward the direction close to the flange 1111. The driving core rod 113 is driven to block the drain outlet 1121 through the abutting effect with the flange 1111.

[0053] Please refer to Figure 7 In this embodiment, the core rod 113 also includes a third diameter section 1133 for blocking the drain port 1121. The third diameter section 1133 is connected to the second diameter section 1132, and the connection is a second limiting slope 1135. The inner cavity of the valve cover 112 near the drain port 1121 is also provided with a first limiting slope 1123, so that when the third diameter section 1133 cooperates with the drain port 1121 of the valve cover 112 to block, the drain connector 121 cooperates with the valve cover 112 to limit.

[0054] The cooperation between the first limiting inclined surface 1123 and the second limiting inclined surface 1135 can prevent the core rod 113 from escaping from the inner cavity formed by the connector body 111 and the valve cover 112 .

[0055] Specifically, the first limiting inclined surface 1123 and the second limiting inclined surface 1135 are both inclined surfaces whose inner diameters decrease successively in a direction approaching the drain port 1121 .

[0056] In this embodiment, a groove for accommodating the seal 140 is opened at the third diameter section 1133 , and a seal 140 is arranged in the groove between the third diameter section 1133 and the drain port 1121 to prevent the third diameter section 1133 from leaking when blocking the drain port 1121 .

[0057] In this embodiment, two sealing members 140 are provided on the outer surface of the valve cover 112 away from the connector body 111 to seal the valve cover 112 and prevent water leakage when the valve cover 112 is connected to the drain connector 121 .

[0058] In this embodiment, a sealing member 140 is also disposed between the valve cover 112 and the connector body 111 to prevent water leakage between the valve cover 112 and the connector body 111 .

[0059] Please refer to Figure 8 In this embodiment, the drain connector 121 includes a connecting section 1211, a water passing section 1212 and a reverse tooth section 1213 which are connected in sequence.

[0060] The connecting section 1211 is provided with a first positioning notch 1214 extending axially from the end face. The first positioning notch 1214 is an L-shaped notch. The outer surface of the valve cover 112 is provided with a positioning protrusion 1122. The positioning protrusion 1122 is accommodated in the first positioning notch 1214, and enables the drain connector 121 and the valve cover 112 to rotate relative to each other, thereby realizing a quick connection between the drain connector 121 and the valve cover 112.

[0061] In this embodiment, the positioning protrusion 1122 is a pin.

[0062] In this embodiment, a second driving member 123 is disposed in the water passing section 1212 , and a second drainage hole 1215 is disposed on the water passing section 1212 . The second drainage hole 1215 allows the inner cavity of the drainage connector 121 to communicate with the drainage pipe 122 .

[0063] Please refer to Figure 5 In this embodiment, the drain pipe 122 includes a steel sleeve 1221 and a hose 1222. The hose 1222 is connected to the inverted tooth section 1213 of the drain connector 121. The steel sleeve 1221 is sleeved on the surface of the hose 1222 corresponding to the inverted tooth section 1213. The multiple inverted teeth arranged on the surface of the inverted tooth section 1213 can be embedded in the hose 1222, and the compression effect of the steel sleeve 1221 can be used to tightly fix the drain pipe 122 to the drain connector 121.

[0064] Please refer to Fig. 9 and Fig.10 In this embodiment, a protective cover 130 is further included. When water drainage is not required, the drainage unit 120 can be removed from the connecting unit 110 , and then the protective cover 130 can be put on the surface of the connecting unit 110 .

[0065] The protection cover 130 includes a bottom surface 132 and a side wall surface 133 . The end surface of the side wall surface 133 away from the bottom surface 132 is provided with a second positioning notch 131 . The second positioning notch 131 is an L-shaped notch and cooperates with the positioning protrusion 1122 of the valve cover 112 for positioning.

[0066] By designing the protective cover 130, when water drainage is not required, the core rod 113 and the first driving member 114 in the connecting unit 110 and the internal sealing member 140 form a first waterproof seal, and then the protective cover 130 is installed on the surface of the valve cover 112 to form a second seal. Two sealing members 140 are also arranged between the protective cover 130 and the valve cover 112 for sealing. At the same time, the bottom surface 132 of the protective cover 130 has no protrusions or other structures, which will not cause the water drainage port 1121 to open.

[0067] In other embodiments, the first driving member 114 and the second driving member 123 may also be magnets, and the drain port 1121 can be opened by the repulsion of like charges from each other. Then, a magnet is also arranged on the bottom surface 132 of the protective cover 130, which has the effect of attraction of opposite charges from each other with the first driving member 114, thereby closing the drain port 1121.

[0068] The present invention provides a water discharge device 100 of a manifold, and its working principle is as follows: The connector body 111 is installed on the manifold, and the core rod 113 blocks the drain port 1121 of the valve cover 112 under the elastic force of the first driving member 114. Then the drain connector 121 is installed on the surface of the valve cover 112. As the drain connector 121 is installed, the second driving member 123 inside it contacts and pushes the core rod 113 to move toward the manifold, and the drain port 1121 is opened. The water in the manifold flows from the first drain hole 1115 on the flange 1111 to the drain cavity 1114, and then flows out from the drain port 1121, and flows into the hose 1222 through the second drain hole 1215 on the drain connector 121, completing the drain process.

[0069] When water drainage is not needed, the drainage unit 120 is removed, and after the core rod 113 loses the supporting effect of the second driving member 123, it is subjected to the elastic force of the first driving member 114 and moves toward the drainage port 1121 and blocks the drainage port 1121. Then, the protective cover 130 is put on the surface of the valve cover 112 to seal it again, thereby ensuring the stable working process of the manifold.

[0070] The embodiment of the present invention provides a drainage device 100 for a manifold, which has no handle, does not require orientation during installation, and has low operation requirements; there is no external switch, and there is no risk of misoperation; the connection unit 110 and the drainage unit 120 are quickly plugged together to form a drainage channel, which is simple and convenient, and has high installation efficiency, and has low requirements for operators and operating space; when the connection unit 110 and the drainage unit 120 are connected to drain water, there is no need to close the system main valve, and pressure drainage can be achieved, which is convenient and easy; a spring protection space is set in the connector body 111 to prevent water flow from impacting the spring, and the structure is reliable. The structure is easy and fast to install, simple to operate, and easy to process, and can prevent the problem of misoperation, and has good application potential.

[0072] The manifold body 200 may adopt a conventional manifold structure on the market, such as a structure consisting of a manifold, a water return and a connecting branch therebetween.

[0073] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
