Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to a high-pressure switching valve and a shower rod. Background Art
[0002] When the high-pressure switching valve is in use, the pressure of the internal flowing water is relatively large, and the water pressure helps the valve plate to fit tightly against the water diversion seat. However, when the water pressure is relatively high, it is possible that the valve plate has a water diversion hole on one side, resulting in a large difference in the water force on both sides, thereby causing the valve plate to be subjected to the water force that causes it to flip, and then a gap appears between the valve plate and the water diversion seat, reducing the sealing degree. For this reason, the utility model provides a switching valve that can solve the above technical problems. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides a switching valve structure with strong sealing performance.
[0004] In a first aspect, a high-pressure switching valve is provided, comprising a valve body, a valve plate and a switching member, wherein:
[0005] The valve body is provided with an installation cavity, one end surface of which is a water diversion seat provided with a plurality of water outlet holes, and the other end is provided with a limiting protrusion surrounding the valve center, and the limiting protrusion points to the water diversion seat.
[0006] The valve plate is provided with a water diversion hole and is rotatably mounted in the mounting cavity, with one end close to the water diversion seat and the other end close to or in contact with the end of the limiting protrusion, thereby preventing the valve plate from turning over.
[0007] The switching member is arranged outside the valve body and is connected to drive the valve plate to rotate. The water diversion hole is connected with any water outlet hole through the rotation of the valve plate.
[0008] The utility model provides a limiting protrusion in the installation cavity that is close to or in contact with the valve plate. When the water pressure is high and a force is applied to the valve plate to make it flip over and separate from the water diversion seat, the limiting protrusion can support the valve plate to avoid the valve plate and the water diversion seat from separating, thereby avoiding the problem of water leakage between the valve plate and the water diversion seat when the water pressure is high.
[0009] Preferably, the limiting protrusion is composed of a plurality of extension arms distributed at intervals.
[0010] Preferably, in order to reduce the friction between the limiting protrusion and the valve plate, a convex point is provided at the end of the limiting protrusion, and the convex point presses against the end surface of the valve plate.
[0011] Preferably, the convex point is a hemispherical convex point, which can further reduce the rotational resistance of the limiting protrusion to the valve plate.
[0012] Preferably, the end edges of the limiting protrusions are all rounded, which can prevent the edges of the limiting protrusions from scratching the valve plate or causing a large sense of blockage when contacting and relatively sliding with the valve plate.
[0013] Preferably, to reduce the forming difficulty of the valve body, the valve body includes a valve seat and a valve cover. Grooves are provided at one end of the valve seat and the valve cover that face each other. The water distribution seat is arranged in the groove of the valve seat, and the limiting protrusions are arranged in the groove of the valve cover.
[0014] Preferably, to improve the assembly tightness and firmness between the valve cover and the valve seat, there is a gap between the limiting protrusion and the groove wall of the valve cover. The groove wall of the valve seat is inserted into the gap, and the valve cover is sleeved on the outer peripheral part of the valve seat.
[0015] Preferably, a compression spring is further arranged in the installation cavity. One end of the compression spring abuts against one end of the valve plate away from the water distribution seat, and can tightly press the valve plate on the water distribution seat to improve the sealing performance.
[0016] In a second aspect, a shower rod is provided, which includes a rod member and the high-pressure switching valve described in the first aspect. The rod member is provided with a communicating water inlet channel, an installation cavity and a water outlet channel. The high-pressure switching valve is installed in the installation cavity, and the water inlet channel is communicated with any water outlet channel through the high-pressure switching valve.
[0017] Preferably, there are three water outlet channels, including a shower head water outlet channel, a shoulder spray water outlet channel and a rod member water outlet channel. The shower head water outlet channel and the water inlet channel are arranged side by side at the bottom end of the rod member. A shoulder spray is installed on the side of the rod member, and the shoulder spray is communicated with the shoulder spray water outlet channel. A water outlet nozzle is provided on the front of the rod member, and the water outlet nozzle is communicated with the rod member water outlet channel.
[0018] As can be seen from the above description of the present invention, the present invention has the following beneficial effects:
[0019] By arranging a limiting protrusion close to or in contact with the valve plate in the installation cavity, when the water pressure is large and a force is applied to the valve plate to make it flip and separate from the water distribution seat, the limiting protrusion can abut against the valve plate to prevent the valve plate from separating from the water distribution seat, thereby avoiding the problem of water leakage between the valve plate and the water distribution seat under the condition of large water pressure;
[0020] A convex point is provided at the end of the limiting protrusion, and the convex point abuts against the end face of the valve plate, which can reduce the friction force between the limiting protrusion and the valve plate;
[0021] The convex point is a hemispherical convex point, which can further reduce the rotational resistance of the limiting protrusion to the valve plate;
[0022] The end edges of the limiting protrusions are all rounded, which can prevent the edges of the limiting protrusions from scratching the valve plate or causing a large sense of blockage when contacting and sliding relative to the valve plate. Description of the Drawings
