Description

Technical Field

[0001] The utility model relates to the field of shower heads, in particular to an adaptive pressure shower head. Background Art

[0002] A shower head, also known as a shower nozzle, is mainly used in bathing and can be used as both a shower device and a water discharge device in a bathtub. The water outlet pressure of a shower head in daily use mainly comes from the pressure of regional water supply and varies due to various factors such as the location, floor height, and secondary water supply pressure of the place where it is located.

[0003] Currently, the shower heads on the market all have a fixed number of water outlet holes. Even for shower heads with multiple water outlet modes, the number of water outlet holes in each mode is fixed and cannot automatically adjust the number of water outlet holes according to pressure and flow rate. With the number and diameter of the water outlet holes fixed, at a specific water pressure, the water flow may be too small or too large. If the water flow is too large, the pressure will be relatively high, causing a stinging sensation, discomfort to the user, and water splashing. If the water flow is too small, there will be no water pressure, resulting in a longer flushing time and an incomplete flushing. Summary of the Utility Model

[0007] Further, the elastic member is a clockwork spring, one end of the clockwork spring is fixedly connected to the top of the water outlet plate, and the other end of the clockwork spring is fixedly connected to the side wall of the rotating shaft column;

[0008] Further, the water outlet plate includes a plurality of water outlet branches, a diversion plate is integrally formed at the top of each water outlet branch, and each water outlet branch corresponds to a group of water outlet nozzles;

[0020] The following further describes the present utility model in detail with reference to the attached Figure 1 - attached Figure 5 drawings:

[0021] An embodiment of the present utility model discloses an adaptive pressure shower head, as shown in Figure 1 , Figure 2As shown in the figure, an adaptive pressure shower head of the present utility model includes a shower head housing 1 and a water inlet grip 2, and further includes a water outlet plate 3 and an elastic member 4; a plurality of groups of water outlet nozzles 11 are provided on the bottom wall of the shower head housing 1, and a rotating shaft column 12 is integrally formed inside the shower head housing 1. The outer side wall of the rotating shaft column 12 is rotatably connected with the water outlet plate 3, and the water outlet plate 3 can close or open the water outlet nozzles 11. An elastic member 4 for resetting the water outlet plate 3 is further provided inside the shower head housing 1; in this embodiment, the water outlet nozzles 11 are provided in groups, and there is a certain interval between multiple groups of water outlet nozzles 11. By providing the water outlet plate 3 and the elastic member 4, the number of water outlet nozzles 11 can be automatically adjusted according to the water pressure. When the water pressure is insufficient, the water outlet plate 3 will close most of the water outlet nozzles 11, and only a small number of water outlet nozzles 11 will discharge water to enhance the water outlet pressure; when the water pressure is sufficient, the water outlet plate 3 will open most of the water outlet nozzles 11 according to the water pressure. As the number of water outlet nozzles 11 increases, the water outlet pressure decreases. By providing the elastic member 4, the water outlet plate 3 can automatically return to the preset position when the water pressure changes. It should be noted that the preset elastic force of the elastic member 4 should enable the water outlet plate 3 to meet the following requirements: when there is no water pressure or the water pressure is the lowest, the elastic member 4 makes the water outlet plate 3 just expose the outermost nozzles of each group of water outlet nozzles 11; as the water pressure increases, the water outlet plate 3 will linearly increase the number of opened nozzles in each group of water outlet nozzles 11, and as the water pressure decreases, the elastic member 4 will push the water outlet plate 3 to linearly decrease the number of opened nozzles in each group of water outlet nozzles 11; when the water pressure is the highest, the water outlet plate 3 will fully open each group of water outlet nozzles 11.

[0022] As Figure 2 , Figure 3 , Figure 5 shown, the elastic member 4 is a clockwork spring. One end of the clockwork spring is fixedly connected to the top of the water outlet plate 3, and the other end of the clockwork spring is fixedly connected to the side wall of the rotating shaft column 12; in this embodiment, a clockwork spring is used as the elastic member 4. The specific structure of the rotating shaft column 12 is as Figure 3 shown. The rotating shaft column 12 is a hollow structure. A fixing hole is provided on the side wall of the rotating shaft column 12. Two fixing plates are integrally formed on the top of the water outlet plate 3. One end of the clockwork spring is fixed between the two fixing plates, and the other end of the clockwork spring is fixedly connected to the rotating shaft column 12 through the fixing hole on the side wall of the rotating shaft column 12. Preferably, the elastic member 4 can also be a torsion spring. One end of the torsion spring is fixed between the two fixing plates, and the other end of the torsion spring is fixedly connected to the rotating shaft column 12 through the fixing hole on the side wall of the rotating shaft column 12 or fixedly connected to the top wall of the shower head housing 1. The elastic member 4 includes but is not limited to a clockwork spring or a torsion spring, as long as it can make the water outlet plate 3 return to the preset position through elastic deformation.

[0023] As Figure 2 , Figure 4As shown, the water outlet piece 3 includes a plurality of water outlet branch pieces 31. A guide plate 32 is integrally formed at the top of each water outlet branch piece 31, and each water outlet branch piece 31 corresponds to a group of water outlet nozzles 11. In this embodiment, the specific shapes of the water outlet piece 3, the water outlet branch pieces 31, and the guide plate 32 are as shown in Figure 4 As shown, the water outlet branch piece 31 is fan-shaped, and each group of water outlet nozzles 11 is also fan-shapedly distributed. The water outlet branch piece 31 can just open or close the corresponding group of water outlet nozzles 11. A through hole is opened at the axial center position of the water outlet piece 3, and the water outlet piece 3 is rotatably connected to the outer side wall of the rotating shaft column 12 through this through hole. It should be noted that the setting direction of the guide plate 32 intersects the water flow direction at the water outlet of the water inlet grip 2 in space. During use, the water flow flowing in from the water inlet grip 2 will push the guide plate 32, thereby driving the entire water outlet piece 3 to rotate. As the water outlet piece 3 rotates, the elastic member 4 will generate an elastic deformation of a corresponding magnitude to obtain elastic potential energy. When the pressure of the water flow decreases, a part of the elastic potential energy of the elastic member 4 is released to push the water outlet piece 3 to rotate in the opposite direction; when the pressure of the water flow increases, the elastic deformation of the elastic member 4 will further increase.

[0024] As Figure 1 、 Figure 2 、 Figure 3 As shown, there are N groups of water outlet nozzles 11 and N water outlet branch pieces 31, where N≥2. In this embodiment, there are 4 groups of water outlet nozzles 11 and 4 water outlet branch pieces 31. Each water outlet branch piece 31 corresponds to a group of water outlet nozzles 11, and there is a gap between each group of water outlet nozzles 11, and the area of the gap part is larger than the area of each water outlet branch piece 31.

[0025] As Figure 1 As shown, a threaded interface 21 for connecting an external water inlet pipe is opened at the end of the water inlet grip 2. In this embodiment, by adding the threaded interface 21, the shower housing 1 can be connected to an external water source pipe through the water inlet grip 2.

[0026] The implementation principle of the embodiment of the present utility model is as follows:

[0027] Threadedly connect the external water source pipe to the water inlet grip 2. Open the shower, and the water flow flowing in from the water inlet grip 2 will push the guide plate 32, thereby driving the water outlet piece 3 to rotate. As the water outlet piece 3 rotates, the elastic member 4 will generate an elastic deformation of a corresponding magnitude and cause the water outlet piece 3 to stop rotating. At this time, the water outlet piece 3 will expose a part of the water outlet nozzles 11;

[0028] When the pressure of the water flow decreases, a part of the elastic potential energy of the elastic member 4 is released to push the water outlet piece 3 to close part of the water outlet nozzles 11, and the water outlet pressure is enhanced by reducing the number of water outlet nozzles 11;

[0029] When the pressure of the water flow increases, the water outlet piece 3 will open more water outlet nozzles 11, and the water outlet pressure is reduced by increasing the number of the water outlet nozzles 11.

[0030] The above shows and describes the basic principles, main features and advantages of the present utility model. Each component mentioned in the present utility model is a common technology in the existing field. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
