[0003] The existing active press-type time-delay valve may become loose during the opening and closing process of the valve body over time, thereby causing the valve body to be unable to effectively block. Utility Model Content

[0004] The purpose of the utility model is to provide a light-touch press-type four-way delay valve. After the water outlet is closed, the water level inside the inner valve cavity continues to rise, and the water barrier rises under the influence of buoyancy, thereby fitting the top spring strap onto the valve plug to complete the water-stopping operation. This can effectively prevent the switch structure from loosening due to the influence of water supply pressure, and can solve the problems in the prior art.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a light-touch, press-type four-way delay valve, comprising a valve body, a valve cover provided on the top of the valve body, the valve cover being connected to the valve body through a flange, a water inlet provided on one side of the valve body, a water outlet provided below the water inlet, wherein a reflux port is provided on the other side of the valve body, and a pressure relief port is provided on one side of the valve cover.

[0006] Furthermore, an inner valve cavity is provided inside the valve body, and an integrally formed valve column is provided at the bottom of the inner valve cavity, wherein the valve column is provided as a hollow structure, and the inner valve cavity is communicated with the water outlet through the valve column.

[0007] Furthermore, the water outlet is communicated with the reflux port, a plug head is provided inside the water outlet, and a water-blocking cover is provided inside the inner valve cavity, and the water-blocking cover is located above the valve column.

[0008] Furthermore, a hook is provided on the top of the water shield, and a spring strap is provided above the hook, wherein the spring strap is rotatably connected to the valve cover, and the water shield is connected to the spring strap via the hook.

[0009] Furthermore, a T-shaped flow channel is provided inside the pressure relief port, and the water inlet is connected to the T-shaped flow channel through a sealing ring tube, wherein the T-shaped flow channel extends through the T-shaped flow channel to above the inner valve cavity.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. In the present invention, after the water level inside the inner valve cavity exceeds the valve column, the water flow can pass through the valve column into the flow channel inside the water outlet. The return port collects and buffers the return water after the water outlet is closed, so as to prevent water from flowing back into the inner valve cavity. At this time, the water level inside the inner valve cavity continues to rise, and the water barrier rises under the influence of buoyancy, thereby fitting the top spring strap to the valve plug to complete the water-stopping operation. After the delay switch is turned on, the water level drops and the spring strap opens, and the water supply operation is resumed. This can effectively prevent the switch structure from becoming loose due to the influence of the water supply pressure. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] In order to solve the problem that the existing active push-type delay valve will become loose during the opening and closing process over time, resulting in the valve body being unable to effectively block; please refer to Figure 1-3 , the utility model provides the following solutions:

[0019] A light-touch, push-type, four-way time-delay valve comprises a valve body 1, a valve cover 103 is provided on the top of the valve body 1, the valve cover 103 is connected to the valve body 1 via a flange, a water inlet 102 is provided on one side of the valve body 1, a water outlet 101 is provided below the water inlet 102, a return port 104 is provided on the other side of the valve body 1, and a pressure relief port 105 is provided on one side of the valve cover 103.

A time-delay switch is provided on the outside of the water outlet 101, which can be pressed to discharge water.

[0020] The valve body 1 is provided with an inner valve cavity 107 inside, and an integrally formed valve column 1071 is provided at the bottom of the inner valve cavity 107, wherein the valve column 1071 is provided with a hollow structure, the inner valve cavity 107 is connected with the water outlet 101 through the valve column 1071, the water outlet 101 is connected with the return port 104, a bolt head 1011 is provided inside the water outlet 101, and a water barrier 106 is provided inside the inner valve cavity 107, and the water barrier 106 is located above the valve column 1071, and a hook 1061 is provided on the top of the water barrier 106, and a spring strap 1062 is provided above the hook 1061, wherein the spring strap 1062 is rotatably connected to the valve cover 103, and the water barrier The cover 106 is connected to the spring strap 1062 via a hook 1061. When the water level inside the inner valve cavity 107 exceeds the valve column 1071, the water can flow through the valve column 1071 into the flow channel inside the water outlet 101. The return port 104 collects and buffers the backflowing water after the water outlet 101 is closed, thereby preventing the water from flowing back into the inner valve cavity 107. At this time, the water level inside the inner valve cavity 107 continues to rise, and the water-blocking cover 106 rises under the influence of buoyancy, thereby making the top spring strap 1062 fit against the valve plug 1053 to complete the water-stopping operation. After the delay switch is turned on, the water level drops and the spring strap 1062 opens, and the water supply operation is resumed.

[0021] A T-shaped flow channel 1052 is provided inside the pressure relief port 105, and the water inlet 102 is connected to the T-shaped flow channel 1052 through a sealing ring tube 1051, wherein the T-shaped flow channel 1052 extends through the T-shaped flow channel 1052 to the top of the inner valve cavity 107, and a valve plug 1053 is provided between the T-shaped flow channel 1052 and the inner valve cavity 107, and the spring strap 1062 is located at the bottom of the valve plug 1053, and the sealing ring tube 1051 can ensure the sealing of the connection.

[0022] Working principle: when the water level inside the inner valve cavity 107 exceeds the valve column 1071, the water can pass through the valve column 1071 into the flow channel inside the water outlet 101, and the return port 104 collects and buffers the return water after the water outlet 101 is closed, so as to prevent water from flowing back into the inner valve cavity 107. At this time, the water level inside the inner valve cavity 107 continues to rise, and the water barrier 106 rises under the influence of buoyancy, thereby fitting the top spring strap 1062 to the valve plug 1053 to complete the water-stopping operation. After the delay switch is turned on, the water level drops and the spring strap 1062 opens, and the water supply operation is resumed.
