The nozzle structure currently used in China is relatively simple. When the pressure in the nozzle changes, the water pressure at the outlet also changes, and it cannot maintain a stable pressure state. Utility Model Content

[0003] In order to solve the technical problems existing in the background technology, the utility model proposes a pressure-stabilizing nozzle assembly.

[0004] The utility model proposes a pressure-stabilizing nozzle assembly, comprising a shell, a water outlet plate, and a pressure regulating member.

A plurality of conical water outlets are provided on the water outlet plate. The expanded ends of the water outlets are located at the front end in the water outlet direction. The pressure regulating member is provided with a plurality of conical stoppers arranged one-to-one corresponding to the water outlets. The conical stoppers are plugged into the water outlets.

[0016] Figure 4 for Figure 3 A schematic diagram of the enlarged structure in FIG. DETAILED DESCRIPTION

[0017] Reference Figure 1-4 The utility model proposes a pressure-stabilizing nozzle assembly, including a shell 1, a water outlet plate 2, and a pressure regulating member 3. The shell 1 is provided with an inlet 11 and an outlet 12. The water outlet plate 2 and the pressure regulating member 3 are sequentially installed in the shell 1 along the water outlet direction. The water outlet plate 2 is provided with a plurality of conical water outlets 21, and the expanded end of the water outlet 21 is located at the front end in the water outlet direction. The pressure regulating member 3 has a plurality of conical stoppers 31 arranged one-to-one corresponding to the water outlets 21. The conical stoppers 31 are inserted into the water outlets 21, and a flow channel for water flow to pass through is formed between the outer wall of the stopper 31 and the inner wall of the water outlet 21, and the stopper 31 can slide along its axial direction to adjust the size of the flow channel.

[0018] The water outlet size of the existing nozzle is fixed. When the water inlet pressure increases, the water outlet pressure also increases accordingly. When the water inlet pressure decreases, the water outlet pressure also decreases accordingly, and it cannot be well maintained in a stable state.

[0019] With the pressure-stabilizing nozzle assembly proposed by the present invention, when the water pressure at the inlet 11 is too high, the block 31 moves outward from the water outlet 21, the flow channel becomes larger, and the water pressure flowing out through the flow channel decreases; when the water pressure at the inlet 11 decreases, the block 31 moves inward from the water outlet 21, the flow channel becomes smaller, and the water pressure flowing out through the flow channel increases, thereby maintaining the outlet water pressure stable when the inlet water pressure is unstable.

[0020] In the above embodiment, in order to facilitate the maintenance, replacement, and assembly of the water outlet plate 2, the water outlet plate 2 is slidably installed in the shell 1, and an annular protrusion 13 is provided on the inner wall of the shell 1 along its radial direction, and the annular protrusion 13 can abut against the rear end face of the water outlet plate 2. The shell 1 is detachably connected to an annular fixing member 7 through a thread, and the fixing member 7 has a fixing portion 71 that can abut against the front end face of the water outlet plate 2. The water outlet plate 2 is clamped between the annular protrusion 13 and the fixing portion 71. When the fixing member 7 is removed from the shell 1, the water outlet plate 2 can be taken out from the shell 1.

[0021] The utility model proposes a first embodiment so that the block 31 in the above embodiment can slide along its axis, a guide plate 4 arranged along the water outlet direction is fixed on the pressure regulating member 3, one end of the guide plate 4 extends to one side of the rear end of the water outlet plate 2 and is fixed with a flow baffle 5, and a spring 6 arranged along the water outlet direction is provided between the flow baffle 5 and the water outlet plate 2.

[0022] The baffle member 5 has a baffle surface that is perpendicular to the direction of water flow. When the water pressure at the inlet 11 is too high, the flow velocity of the water flow increases, and the water flow acts on the baffle surface to squeeze the baffle member 5, so that the baffle member 5 moves in the direction close to the water outlet plate 2. At the same time, the baffle member 5 drives the block 31 on the pressure regulating member 3 to move in the direction away from the water outlet plate 2, the flow channel becomes larger, and the water pressure passing through the flow channel becomes smaller than the water pressure before the flow channel becomes larger. Similarly, when the water pressure at the inlet 11 decreases, the flow velocity decreases, and the force acting on the baffle surface decreases accordingly. The baffle member 5 is acted upon by the elastic force of the spring 6 to move in the direction away from the water outlet plate 2, and drives the block 31 to move into the water outlet 21, and the flow channel becomes smaller. At this time, the pressure of water flowing out through the flow channel increases compared to the pressure before the flow channel becomes smaller, thereby allowing the water pressure of the water to remain stable.

[0023] It should be further explained that, in the above embodiment, the baffle 5 and the water outlet 21 are arranged in a staggered manner.

[0024] In the above embodiment, a guide groove is opened in the annular protrusion 13 along its radial direction, and the guide plate 4 is slidably connected with the guide groove along the water outlet direction. In order to make the movement of the stopper 31 more stable, the number of guide plates 4 is two and they are arranged symmetrically, and the distance between the two guide plates 4 is greater than the diameter of the water outlet plate 2.

[0025] At this time, the process of assembling the water outlet plate 2, the pressure regulating component 3 and its accessory components into the shell 1 is as follows: first, pass the guide plate 4 through the guide groove along the length direction of the shell 1, and leave part of the guide plate 4 outside the shell 1, then place the water outlet plate 2 between the two guide plate 4 parts located outside the shell 1 along the radial direction of the shell 1, push the pressure regulating component 3 so that the block 31 can enter the water outlet 21, then push the pressure regulating component 3 into the shell 1, and finally screw the fixing component 7 onto the shell 1 to complete the assembly.

[0026] It should be further explained that when the water outlet plate 2 is circular, the water outlet plate 2 may be displaced during use, resulting in the block 31 being unable to correspond to the water outlet 21. To solve the above problem, the water outlet plate 2 is also provided with a positioning rod, and a positioning groove for the positioning rod to be inserted is provided on the annular protrusion 13. The positioning rod and the positioning groove are arranged along the length direction of the shell 1. For details, refer to Figure 1-2 .

[0027] The utility model also proposes a second embodiment so that the stopper 31 in the above embodiment can slide along its axis, a screw rod 32 is rotatably mounted on the pressure regulating member 3, and a threaded hole adapted to be screwed with the screw rod 32 is provided on the annular protrusion 13.

[0028] The user can rotate the screw 32 to adjust the size of the flow channel according to the use requirements. Figure 3-4 .

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
