Description

Technical Field

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

[0002] Most existing showerheads use a mechanical diverter valve + ordinary thermostatic mixing valve / water heater temperature control solution. When a user switches from "rain shower" to "massage" or "concentrated rinse", the total flow rate changes abruptly, causing dynamic lag in the control of the mixing valve or water heater; coupled with the stagnation of hot and cold water in the flow channel and changes in pressure drop, this often leads to a sudden drop or rise in the outlet water temperature (commonly known as cold / thermal shock), causing discomfort and even the risk of scalding. Utility Model Content

[0003] The purpose of this invention is to provide a shower head that uses a small-capacity branch hollow pipe and a large-capacity third hollow pipe connected in parallel in the water flow channel. At the moment the shower head switches water outlet modes, it temporarily absorbs / releases a small flow of water to ensure the stability of water pressure, water flow and temperature.

[0004] The solution presented in this application is implemented through the following steps.

[0005] The first aspect of this application provides a shower head, comprising a plurality of coaxially fixedly connected hollow tubes and a water outlet module communicating with the end of the last hollow tube. All the hollow tubes form axial water flow channels inside, communicating with the water inlet of the water outlet module, so that water flows out through the spray nozzles of the water outlet module; wherein: A water pressure regulator connected to the water flow channel is vertically fixed to the first hollow pipe near the water inlet of the water flow channel for regulating the water pressure in the water flow channel. A temperature regulator is vertically fixed at the connection between the first hollow tube and the second hollow tube for adjusting the temperature of the water in the water channel. The second hollow tube is vertically fixed to a water flow regulator that is connected to the water flow channel, and is used to switch the shape of the water flow in the water flow channel; The two ends of the third hollow tube are coaxially sleeved with the ends of the second and fourth hollow tubes; wherein the inner diameter of the third hollow tube is larger than the inner diameter of the second hollow tube. The end of the third hollow tube near the fourth hollow tube is vertically and fixedly connected to an internally hollow branch hollow tube that communicates with the third hollow tube. The volume of the branch hollow tube is smaller than that of the third hollow tube.

[0006] A water pressure regulator is used at the inlet near the water flow channel to regulate the water pressure in the water flow channel, and a temperature regulator is used at the end of the first hollow pipe to regulate the water temperature. A water flow regulator is also installed in the second hollow pipe to switch the shape of the water flow in the water flow channel, which can ensure that the water pressure, temperature and water flow all meet the set requirements.

[0007] Furthermore, a small-capacity branch hollow pipe is connected in parallel with a large-capacity third hollow pipe in the water flow channel. At the moment the showerhead switches its water flow mode, it temporarily absorbs / releases a small flow of water. When the water flow from the outlet module gradually decreases after the mode switch, the instantaneous increase in water volume in the main channel (the water flow channel within the third hollow pipe) causes a brief pressure surge. This water flow is "absorbed" by the small-capacity branch hollow pipe (water / air in the small cavity is slightly compressed and then released delayedly through micropores), thus mitigating the instantaneous drop in total flow. Conversely, when the water flow from the outlet module gradually increases after the mode switch, a short-term "water shortage" occurs in the main channel. The small-capacity branch hollow pipe releases the previously stored water to compensate for the steep increase in total flow, thus preventing the heat source / mixing end from being "evacuated / blocked." The source of the transient temperature change at the outlet is weakened, ensuring the stability of the water pressure, flow, and temperature.

[0008] The shower head described in the first aspect may optionally include a U-shaped tube, one end of which is coaxially fixed and connected to the end of the fourth hollow tube away from the third hollow tube, and the other end of which is fixedly connected and connected to the inlet of the water outlet module.

[0009] A U-shaped pipe is used to fix and connect the pipe body forming the water flow channel to the water outlet module, providing stable support to the water outlet module while avoiding the water outlet area of ​​the water outlet module, thus preventing the components on the pipe body structure from drying out.

[0010] As described in the first aspect, the shower head may optionally include an array of multiple chambered water outlet units, each water outlet unit having a water inlet hole on its side; wherein the water inlets of two adjacent water outlet units are connected.

[0011] It employs an array of multiple water outlet units to provide a large water outlet area, and through interconnected water inlets, it ensures that the water output of multiple water outlet units is evenly distributed, thereby improving the comfort of use.

[0012] As described in the first aspect, the shower head may optionally have a polygonal shape for the water outlet unit.

[0013] The use of polygonal shapes facilitates the integrated installation of multiple water outlet units in an array, thereby improving the degree of integration.

[0014] As described in the first aspect, the shower head may optionally have a slot on one side of each water outlet unit near the water inlet, and a buckle fixedly connected to the corresponding position on the side opposite to the slot, so that two adjacent water outlet units are fixedly connected by the buckle and the slot.

[0015] By setting buckles and slots on two opposite sides of the water outlet unit, the sides of the two water outlet units can fit together after being fastened, so that the water inlet holes can be connected; this facilitates the installation and disassembly of two adjacent water outlet units, improving structural stability and making disassembly and maintenance easier.

[0016] As described in the first aspect, the shower head may optionally include: The top cover has a water inlet hole on its side; The bottom cover, together with the top cover, forms a sealed chamber; The water outlet structure is coaxially fixed in the chamber, and one end of the water outlet structure is fixedly connected to an inlet pipe that passes through the inlet hole.

[0017] The system uses a sealed chamber formed by a top cover and a bottom cover. Water enters through the inlet pipe of the water outlet structure in the chamber and flows out through the outlet hole, creating a shower effect.

[0018] As described in the first aspect, the shower head may optionally include a flow sensor coaxially fixed to the water outlet structure.

[0019] A flow sensor is used to measure the amount of water flowing out of the water outlet structure, which makes it easier to adjust the various regulators in the pipe structure that forms the water flow channel to form a stable water pressure and improve the shower experience.

[0020] As described in the first aspect, the shower head may optionally have a fixing groove in the center of the water outlet structure for fixing the flow sensor.

[0021] A flow sensor is fixed at the center of the water outlet structure to ensure the accuracy of the measurement results.

[0022] As described in the first aspect, the shower head may optionally have a water outlet hole at the corner of the end face of the top cover, and the shower head may further include a spray nozzle assembly fixed to the water outlet hole and communicating with the chamber; an O-ring is sleeved between the spray nozzle assembly and the water outlet hole.

[0023] The water in the chamber is discharged through the outlet hole using a nozzle assembly. The nozzle assembly is detachably fixed to the top cover by an O-ring, which ensures the chamber is sealed and facilitates subsequent descaling and maintenance.

[0024] The shower head described in the first aspect may optionally include a main control chip for controlling the switching of the water pressure regulator, the temperature regulator, and the water flow regulator.

[0025] By using a main control chip to control each regulator, the temperature, pressure, and mode of the water flow in the water channel are jointly controlled, which can achieve constant temperature and pressure stability when the user switches working modes, thus improving the user experience.

[0028] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0029] Existing showerheads typically have the following drawbacks: Firstly, the water temperature is unstable, resulting in cold / thermal shocks. When users switch between different water flow modes (such as rain shower, massage, and rinse), the showerhead's water distribution structure causes a sudden change in the total flow rate, causing a lag in the response of the thermostatic mixing valve or the water heater's temperature control system. As a result, the water temperature drops or rises suddenly in a short period of time, producing significant cold / thermal shocks, which may cause scalding or discomfort in severe cases.

[0030] Secondly, the water flow switching method is crude and cannot achieve a smooth transition. Traditional showerheads mostly have an integral structure, and the water flow mode switching relies on a mechanical valve to switch all the spray channels at once. This "whole head switching" method lacks the ability to independently adjust each spray hole or area. During the switching process, the water pressure and flow rate change drastically, resulting in uneven water flow, obvious mode jumps, and an abrupt experience.

[0031] Thirdly, the lack of intelligent zoning and linkage control mechanisms means that the temperature control, water flow mode, and water pressure adjustment functions of existing showerheads are independent and cannot form a coordinated control. When the mode or pressure changes, the system cannot actively predict temperature fluctuations or compensate in advance, lacking intelligent linkage and feedforward control logic, resulting in low overall control accuracy and poor stability.

[0032] Fourthly, traditional spray surfaces are mostly integral structures, which can only be switched as a whole and lack the ability to independently adjust the flow of different nozzle areas. They cannot transition in small steps or gradually, and therefore it is difficult to suppress instantaneous fluctuations in temperature and flow.

[0033] Based on this, and addressing the problems of existing technologies such as instantaneous fluctuations in outlet water temperature, susceptibility to cold / thermal shocks, sudden changes in water flow / pressure during switching modes (rain shower / massage / rinse, etc.), abrupt experience, and lack of temperature-water pressure-mode linkage control, this embodiment provides a shower head with a honeycomb structure aesthetic and shock-resistant temperature stabilization capabilities. This shower head features a collaborative design at both the structural and control ends, enabling it to suppress sudden jumps in total flow rate and quickly stabilize the outlet water temperature during mode switching, thereby improving comfort and safety.

[0034] like Figure 1 The schematic diagram of the shower head shown includes several coaxially fixed hollow tubes and a water outlet module 10 connected to the end of the last hollow tube. The interior of all the hollow tubes forms an axial water flow channel that is connected to the water inlet of the water outlet module 10 so that water flows out through the spray hole of the water outlet module 10.

[0035] Multiple hollow tubes are coaxially fixedly connected, forming an axially connected space inside as a water flow channel, which facilitates the entry of cold water from the inlet. Then, through the action of multiple controllers in the middle, the pressure and temperature of the cold water are regulated, and the water flows through the outlet to the water outlet module 10 to form a shower.

[0036] In this embodiment, four hollow tubes are coaxially fixedly connected, namely, the first hollow tube 11, the second hollow tube 12, the third hollow tube 13, and the fourth hollow tube 14. The first hollow tube 11 is close to the water inlet 101 of the water channel, and the fourth hollow tube 14 is close to the water outlet of the water channel. The first hollow tube 11 is vertically fixed with a water pressure regulator 111 that communicates with the water channel to regulate the water pressure in the water channel.

[0037] A temperature regulator 110 is vertically fixed at the connection between the first hollow tube 11 and the second hollow tube 12. This regulator is used to adjust the temperature of the water in the water channel, thereby heating the water in the channel. The temperature is adjusted according to the user-set temperature to ensure that the temperature of the water exiting the water outlet module 10 matches the user-set temperature. A water flow regulator 121, which communicates with the water channel, is vertically fixed to the second hollow tube 12. This regulator is used to switch the shape of the water flow in the water channel.

[0038] A water pressure regulator 111 is used at the water inlet 101 near the water flow channel to regulate the water pressure in the water flow channel, and a temperature regulator 110 is used at the end of the first hollow pipe 11 to regulate the water temperature. A water flow regulator 121 is also set in the second hollow pipe 12 to switch the shape of the water flow in the water flow channel, which can ensure that the water pressure, temperature and water flow meet the set requirements.

[0039] The two ends of the third hollow tube 13 are coaxially sleeved with the ends of the second hollow tube 12 and the fourth hollow tube 14; wherein, the inner diameter of the third hollow tube 13 is larger than the inner diameter of the second hollow tube 12; the end of the third hollow tube 13 near the fourth hollow tube 14 is vertically and fixedly connected to an internally hollow branch hollow tube that communicates with the third hollow tube 13, and the volume of the branch hollow tube is smaller than the volume of the third hollow tube 13.

[0040] In this embodiment, the inner diameters of the first hollow tube 11, the second hollow tube 12, and the fourth hollow tube 14 are not significantly different. The inner diameter of the third hollow tube 13 is much larger than that of the second hollow tube 12 and also much larger than that of the fourth hollow tube 14, thus forming a water storage chamber inside the third hollow tube 13. The axial water flow channel formed by the first hollow tube 11, the second hollow tube 12, the third hollow tube 13, and the fourth hollow tube 14 can be understood as the main channel for water flow.

[0041] A hollow branch pipe 15, which is vertically fixed to the end of the third hollow pipe 13 near the fourth hollow pipe 14 and communicates with the third hollow pipe 13, serves as a branch for water flow. The volume of the branch hollow pipe 15 is smaller than that of the third hollow pipe 13, meaning the water storage volume in the branch is much smaller than the volume of the third hollow pipe 13 in the main channel. Water in the main channel can flow into the branch, and water in the branch can also flow into the main channel.

[0042] A small-capacity branch hollow pipe 15 is connected in parallel with a large-capacity third hollow pipe 13 in the water flow channel. At the moment the showerhead switches its water flow mode, it temporarily absorbs / releases a small flow of water. When the water flow of the outlet module 10 gradually decreases after the mode switch, the instantaneous increase in water volume in the main channel (the water flow channel within the third hollow pipe 13) causes a short-term pressure surge. This water flow is "absorbed" by the small-capacity branch hollow pipe 15 (water / air in the small cavity is slightly compressed and then released delayedly through micropores), thus mitigating the instantaneous drop in total flow. Conversely, when the water flow of the outlet module 10 gradually increases after the mode switch, a short-term "water shortage" occurs in the main channel. The small-capacity branch hollow pipe 15 releases the previously stored water to compensate for the steep increase in total flow, thus preventing the heat source / mixing end from being "evacuated / blocked." The source of the transient temperature change at the outlet is weakened, ensuring the stability of the water pressure, flow, and temperature.

[0043] Continue as Figure 1 As shown, the shower head also includes a U-shaped tube. One end of the U-shaped tube is coaxially fixed and connected to the end of the fourth hollow tube 14 away from the third hollow tube 13, and the other end of the U-shaped tube is fixedly connected and connected to the inlet 101 of the water outlet module 10. By using the U-shaped tube to fix and connect the pipe body forming the water flow channel to the water outlet module 10, a stable support is provided to the water outlet module 10 while avoiding the water outlet area of ​​the water outlet module 10, thus preventing the components on the pipe structure from drying out.

[0044] like Figure 1 and Figure 2 As shown, the water outlet module 10 includes multiple arrays of chambered water outlet units 100, each with a water inlet hole on its side; wherein the water inlets of two adjacent water outlet units 100 are connected. The array of multiple water outlet units 100 provides a large water outlet area, and the connected water inlets ensure even water output from the multiple water outlet units 100, thereby improving user comfort.

[0045] For example, the shape of the water outlet unit 100 is polygonal. Using polygons facilitates the integrated installation of multiple water outlet units 100 in an array, thereby improving the integration level. Figure 2 The diagram illustrates the shape of a hexagon, but it can also be a polygon with other numbers of sides, which will not be described in detail in this embodiment.

[0046] like Figure 3 and Figure 4As shown, each water outlet unit 100 has a slot 112 on one side near the water inlet, and a buckle 113 is fixedly connected to the corresponding position on the opposite side of the slot 112, so that two adjacent water outlet units 100 are fixedly connected by the engagement of the buckle 113 and the slot 112. By setting the buckle 113 and the slot 112 on the two opposite sides of the water outlet units 100 respectively, it is easy for the sides of the two water outlet units 100 to fit together after being fastened, so that the water inlet is connected; it is convenient for the installation and disassembly of two adjacent water outlet units 100, which improves the structural stability and facilitates disassembly and maintenance.

[0047] like Figure 5 As shown, the water outlet unit 100 includes a coaxially arranged upper cover 102, a water outlet structure 104, and a bottom cover 106. The upper cover 102 and the bottom cover 106 can be closed, and the water outlet structure 104 is located inside the upper cover 102 and the bottom cover 106. Specifically, the upper cover 102 has a water inlet hole on its side. The bottom cover 106 closes with the upper cover 102 to form a sealed chamber. The water outlet structure 104 is coaxially fixed inside the chamber, and one end of the water outlet structure 104 is fixedly connected to an inlet pipe 105 that passes through the water inlet hole. The inlet pipe 105 communicates with a U-shaped pipe, so that water flows from the water channel formed by multiple hollow pipes through the U-shaped pipe to the water outlet unit 100 to achieve showering. The closed upper cover 102 and the bottom cover 106 form a sealed chamber. Water enters through the inlet pipe 105 of the water outlet structure 104 in the chamber and flows out through the water outlet hole, creating a showering effect.

[0048] In addition, the water outlet unit 100 also includes a flow sensor 136 coaxially fixed with the water outlet structure 104. The flow sensor 136 measures the amount of water flowing out of the water outlet structure 104, which facilitates the adjustment of various regulators in the pipe structure that forms the water flow channel to form a stable water pressure and improve the showering experience.

[0049] like Figure 5 As shown, a fixing groove 103 is provided in the center of the water outlet structure 104 to fix the flow sensor 136 and ensure the accuracy of the measurement results.

[0050] like Figure 2 and Figure 5 As shown, a water outlet is provided at the corner of the end face of the top cover 102. The shower head also includes a spray nozzle assembly 122 fixed to the water outlet and communicating with the chamber; an O-ring is fitted between the spray nozzle assembly 122 and the water outlet. The spray nozzle assembly 122 is used to allow water in the chamber to flow out through the water outlet. The spray nozzle assembly 122 is detachably fixed to the top cover 102 by the O-ring, which ensures the chamber is sealed and facilitates subsequent descaling and maintenance.

[0051] As with the showerhead in the first aspect, optionally, a main control chip is also included to control the switching of the water pressure regulator 111, the temperature regulator 110, and the water flow regulator 121. By using the main control chip to control each regulator, the temperature, water pressure, and mode of the water flow in the water channel can be jointly controlled, achieving constant temperature and pressure stability when the user switches between working modes, thus improving the user experience.
