Description

Technical Field

[0001] This utility model relates to the field of shower head water outlet, and in particular to a water outlet nozzle. Background Technology

[0002] A shower head is a shower facility. A water outlet pipe is pre-installed on the wall, and the shower head is connected to the water outlet pipe through a water outlet hose to enable water to flow from the shower head. The shower head can divide the water flow into multiple streams and spray them out in a dispersed manner, thereby increasing the water flow area. The existing shower head includes a hand handle and a shower head. The shower head includes a water outlet body, a front cover, and a nozzle. The front of the water outlet body is open and hollow. The front cover is snapped onto the open front of the water outlet body. The nozzle has a water outlet panel and a water outlet nozzle. The water outlet panel is located between the front cover and the water outlet body, and the water outlet nozzle is located on the front side of the water outlet panel. The front cover has an extension hole corresponding to the position of the water outlet nozzle, allowing the water outlet nozzle to extend beyond the front side of the front cover. The water outlet nozzle has a hollow trumpet structure that is open at both ends and gradually narrows from back to front. The water outlet panel has a water outlet hole corresponding to the position of the water outlet nozzle, which communicates with the water outlet nozzle and is connected to the hollow cavity of the water outlet body. One end of the hand handle is connected to one end of the water outlet body and communicates with it. The other end of the hand handle is connected to the water outlet pipe through a water outlet hose. In use, water flows out of the water outlet pipe, passes through the handle, the water outlet body, and the nozzle, and finally sprays out from the water outlet nozzle.

[0003] Existing showerheads rely on the horn structure of the nozzles to pressurize the water flow when it sprays out, thus increasing the water pressure. However, the internal space of the nozzles remains fixed, and the nozzles do not adapt to changes in water pressure. As a result, the nozzles cannot change the overall water outlet area with changes in water pressure. Consequently, under low water pressure, the water has little or no impact, affecting the performance.

[0004] In view of this, the inventors of this case conducted in-depth research on the problem, which led to the creation of this case. Utility Model Content

[0005] The purpose of this utility model is to provide a water outlet to solve the problem that existing shower heads have no impact or only a small impact when the water pressure is low, which affects the shower experience.

[0006] To achieve its purpose, this utility model adopts the following technical solution:

[0007] A water outlet includes a water outlet panel and a water outlet nozzle. With one side of the water outlet panel as the front and the other as the rear, the water outlet nozzle is open at both ends and horizontally mounted on the front side of the water outlet panel along the front-rear direction. A water outlet hole, communicating with the water outlet nozzle, is provided on the rear side of the water outlet panel at a position corresponding to the water outlet nozzle. The water outlet nozzle is an elastic water outlet hose capable of radially expanding according to changes in water pressure to increase the water outlet area. The elastic water outlet hose has a first water outlet section and a second water outlet section, both of which are two-part... The structure is a flat, open column with the rear end of the first water outlet section connected to the front side of the water outlet panel and correspondingly connected to the water outlet hole. The front end of the first water outlet section is connected to the rear end of the second water outlet section. The rear end opening, the front end opening, the rear end opening, and the front end opening of the second water outlet section are all deformable flat openings that can reduce the cross-sectional area of ​​the opening as the water pressure decreases. The axes of each deformable flat opening are on the same straight line, and the outer diameter of each deformable flat opening gradually decreases from back to front.

[0008] Both the first and second water outlet sections are flat cylindrical structures that gradually narrow from back to front, and both the first and second water outlet sections have elliptical cross-sections.

[0009] The deformed flat opening is an elliptical opening, and the major and minor radii of each elliptical opening are on the same straight line. The major and minor radii of each elliptical opening gradually decrease from back to front.

[0010] The water outlet panel is a circular panel, and the major radius of each elliptical opening extends along the radial direction of the water outlet panel.

[0011] The front end of the first water outlet section and the rear end of the second water outlet section are connected by an arc-shaped section.

[0012] The flexible water outlet hose is a flexible silicone tube.

[0013] This new type of water nozzle, during assembly, involves installing the water outlet panel between the shower head front cover and the water outlet body, with the water outlet nozzle extending from the front end of the shower head front cover. The water outlet body is connected to the water outlet pipe, thus completing the assembly. In use, water enters the water outlet body and flows through the water outlet holes on the water outlet panel into the water outlet nozzle, passing sequentially through the first and second water outlet sections, and finally spraying out from the front end of the second water outlet section. Under high water pressure, both the first and second water outlet sections expand into columnar structures, and each deformed flat orifice transforms into a circular orifice. Because the area of ​​the circular orifice is larger than that of the flat orifice, the water outlet area at the front end of the second water outlet section is increased, preventing excessive water impact force from the nozzle. Under the lowest tap water pressure, the shapes of the first and second water outlet sections remain unchanged, and the shapes of each deformed flat orifice also remain unchanged, ensuring a certain water outlet area and maintaining a consistent water flow effect. Compared with existing technologies, when the water pressure increases, the first and second water outlet sections can expand accordingly, so that the water outlet area of ​​the nozzle changes with the water pressure. That is, the water flow size is changed by controlling the change of the water outlet area at the front end of the nozzle through the change of water pressure. Even at low water pressure, the nozzle can still ensure a certain water impact force, resulting in better performance. Attached Figure Description

[0018] To further explain the technical solution of this utility model, a detailed description is provided below in conjunction with the accompanying drawings.

[0019] A type of water outlet, such as Figures 1-4 As shown, the shower head includes a water outlet panel 1 and a water outlet nozzle 2. With one side of the water outlet panel as the front and the other side as the rear, the water outlet nozzle 2 is horizontally installed on the front side of the water outlet panel 1 in the front-rear direction. The water outlet nozzle 2 is a hollow structure with open ends. A water outlet hole 100 connected to the water outlet nozzle 2 is provided on the rear side of the water outlet panel 1 at the position corresponding to the position of the water outlet nozzle 2. The water outlet hole 100 is a circular structure. In use, the water outlet nozzle is installed between the shower head front cover and the water outlet body. The water flows into the water outlet body and then into the water outlet nozzle through the water outlet hole.

[0020] The water nozzle 2 is an elastic water outlet hose that can radially expand the water outlet nozzle 2 according to the change of water flow pressure, thereby increasing the water outlet area. The elastic water outlet hose is an elastic silicone tube. The elastic water outlet hose has a first water outlet section 21 and a second water outlet section 22. Both the first water outlet section 21 and the second water outlet section 22 are flat cylindrical structures that are open at both ends and gradually narrow from back to front. The cross-sections of the first water outlet section 21 and the second water outlet section 22 are both elliptical structures. The rear end of the first water outlet section 21 is connected to the front side of the water outlet panel 1 and is correspondingly connected to the water outlet hole 100. The front end of the first water outlet section 21 is connected to the rear end of the second water outlet section 22. That is, the front end of the first water outlet section 21 and the rear end of the second water outlet section 22 are connected by an arc-shaped section 23. During use, due to the limited water pressure of the tap water outlet, at high pressure, the water flows from the outlet hole into the first outlet section 21, causing elastic deformation. The first outlet section expands from a flat cylindrical structure to a cylindrical structure. Similarly, the second outlet section 22 also becomes a cylindrical structure. Ultimately, the water flows out from the front end of the second outlet section 22 with a circular cross-section, increasing the water outlet area. The initial state of the flat cylindrical structure of the nozzle is adapted to the lowest tap water pressure. At the lowest tap water pressure, the nozzle experiences almost no elastic deformation, and the water flows out from the front end of the second outlet section 22 with a flat cross-section, reducing the nozzle's outlet area while maintaining a certain outlet area and impact force. In other words, at low water pressure, the outlet area is smaller, allowing the nozzle to still possess a certain impact force.

[0021] The rear end opening of the first water outlet section 21, the front end opening of the first water outlet section 21, the rear end opening of the second water outlet section 22, and the front end opening of the second water outlet section 22 are all deformable flat openings that can reduce the cross-sectional area of ​​the opening diameter as the water pressure decreases. The axes of each deformable flat opening are on the same straight line, and the outer diameter of each deformable flat opening gradually decreases from back to front. Specifically, the deformable flat opening is an elliptical opening, and the major radius of each elliptical opening is on the same straight line. The major and minor radii of each elliptical opening gradually decrease from back to front. The water outlet panel 1 is a circular panel, and the major radius of each elliptical opening extends along the radial direction of the water outlet panel 1. In application, since each deformable flat opening gradually decreases from back to front, the inlet area at the rear end of the water outlet nozzle is increased, the fluid resistance is reduced, and the water pressure at the second water outlet section 22 of the water outlet nozzle has a greater pressure to open the second water outlet section 22, thereby making the front water outlet area of ​​the water outlet nozzle larger and avoiding excessive water flow impact.

[0022] This new type of water nozzle, during assembly, involves installing the water outlet panel 1 between the shower head front cover and the water outlet body, with the water outlet nozzle extending from the front end of the shower head front cover. The water outlet body is connected to the water outlet pipe, thus completing the assembly. In use, water enters the water outlet body and flows through the water outlet holes of the water outlet panel 1 into the water outlet nozzle 2, passing sequentially through the first water outlet section 21 and the second water outlet section 22, finally spraying out from the front end of the second water outlet section 22. Under high water pressure, both the first water outlet section 21 and the second water outlet section 22 expand into columnar structures, and each deformed flat orifice changes from an elliptical opening to a circular opening, thereby increasing the water outlet area at the front end of the second water outlet section 22 and preventing excessive water impact force from the nozzle. Under the lowest tap water pressure, the shapes of the first water outlet section 21 and the second water outlet section 22 remain unchanged from their initial state, and the shapes of each deformed flat orifice also remain unchanged, ensuring a certain water outlet area for the nozzle and maintaining a certain water output effect. Compared with existing technologies, when the water pressure increases, the first and second water outlet sections can expand accordingly, so that the water outlet area of ​​the nozzle changes with the water pressure. That is, the water flow size is changed by controlling the change of the water outlet area at the front end of the nozzle through the change of water pressure. Even at low water pressure, the nozzle can still ensure a certain water impact force, resulting in better performance.

[0023] The product form of this utility model is not limited to the illustrations and embodiments in this case. Any appropriate changes or modifications made to it based on similar ideas should be considered as not departing from the patent scope of this utility model.
