Description

Technical Field

[0001] This utility model relates to the field of shower technology, and in particular to a water distribution device and a shower device using the same. Background Technology

[0002] With the upgrading of residents' living standards, water heaters, as core equipment in household and commercial bathroom systems, have formed two main technological branches: gas-fired and storage-type electric water heaters. Gas water heaters, relying on their instantaneous water supply and lack of capacity limitations, dominate in continuous water use scenarios such as apartments and hotels; while electric water heaters, with their flexible installation and high safety, have become the preferred solution for the renovation of old residential buildings and temporary locations. In addition, the two types of equipment also have compatibility barriers due to differences in their working principles: gas water heaters require a certain water pressure and flow threshold to ignite, while electric water heaters can be used with low-flow showers (such as water-saving showerheads). The contradiction in the end-user water flow requirements makes it difficult for shower systems to be reused across platforms.

[0003] In existing technologies, there is a significant trend towards integrated shower functions. For example, patent CN119423597A discloses an integrated shower device that uses a water-diverting mechanism to direct a portion of the water flow to a built-in foam functional area, allowing the water to mix with shower gel before being output, achieving a seamless "shower while taking out the gel" operation. While this design improves the user experience, it further exacerbates the compatibility issues with gas water heaters: the water-diverting mechanism forces the flow of the main water outlet to be diverted, with actual measurements showing a 30% to 40% decrease in total flow. The diverted flow often falls below the gas water heater's start-up threshold, causing the device to fail to ignite properly. This contradiction is particularly prominent in high-frequency equipment replacement scenarios such as rental housing and serviced apartments, where users expect to retain the convenience of a multi-functional shower terminal but require additional pipe modifications to match the gas equipment, significantly increasing operating costs.

[0049] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0050] The following is in conjunction with the appendix Figures 1 to 11 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0051] In existing technologies, shower water distribution devices typically use a single valve to control water flow. When the user activates the foam generation function, the water flow in the main outlet channel is significantly reduced due to the diversion effect. This decrease in flow often prevents the gas water heater from reaching the minimum flow threshold required for ignition, forcing users to make trade-offs between using the function and hot water supply. This severely restricts the widespread application of multi-functional shower equipment.

[0052] This utility model proposes a water distribution device, including a body 1. The body 1 includes a lower water outlet valve core cavity 111, a top spray valve core cavity 112, a handheld shower valve core cavity 113, a foaming water valve core cavity 12, and a gas valve core cavity 13. Each of the lower water outlet valve core cavity 111, the handheld shower valve core cavity 113, the top spray valve core cavity 112, the foaming water valve core cavity 12, and the gas valve core cavity 13 is provided with a control valve core. The control valve core is used to control the connection or closure of the water inlet and outlet of the corresponding cavity.

[0053] The main body 1 is provided with a valve body inlet 100, a lower outlet 101, a foaming water outlet 102, a top spray outlet 103, and a handheld shower outlet 104. The main body 1 is provided with an inlet chamber 140 and a drainage chamber 15.

[0054] The valve body inlet 100 is connected to the inlet end of the inlet chamber 140, the outlet end of the inlet chamber 140 is connected to the inlet end of the diversion chamber 15 and the inlet end of the lower outlet valve core chamber 111, and the outlet end of the lower outlet valve core chamber 111 is connected to the lower outlet 101.

[0055] One of the outlet ends of the water drainage chamber 15 is connected to the inlet end of the hand shower valve core chamber 113, and the outlet end of the hand shower valve core chamber 113 is connected to the hand shower outlet 104.

[0056] One of the outlet ends of the drainage water chamber 15 is connected to the inlet end of the top spray valve core chamber 112, and the outlet end of the top spray valve core chamber 112 is connected to the top spray outlet 103.

[0057] One outlet of the drainage water chamber 15 is connected to the inlet of the foaming water valve core chamber 12. The outlet of the foaming water valve core chamber 12 is connected to the foaming water outlet 102. The outlet of the foaming water valve core chamber 12 is also connected to the inlet of the gas valve core chamber 13. The outlet of the gas valve core chamber 13 is connected to the lower outlet 101.

[0058] Specifically, when the shower using this water distribution device is applied to an electric water heater, and the water heater is activated simultaneously with the foaming function to meet the required flow rate threshold, the control valve core in the gas valve core cavity 13 can be closed. Water flowing from the foaming water valve core cavity 12 will not flow out of the lower outlet 101, thus saving water. When the water distribution device is applied to a gas water heater, the control valve core in the gas valve core cavity 13 needs to be opened. Water flows from the foaming water valve core cavity 12 to the foaming water outlet 102, while another stream flows from the foaming water valve core cavity 12 through the gas valve core cavity 13 and out of the lower outlet 101. This ensures that the shower's foaming function is met while also satisfying the flow rate threshold required for the gas water heater's ignition.

[0059] Compared to existing technologies, traditional water distribution devices, such as those in patent CN119423597A, use a single valve core to control dual channels. The flow diversion process during the foaming function inevitably leads to a linear decrease in the flow rate of the main water outlet. In contrast, this solution, by setting up multiple independently controlled valve core cavities, ensures that the water flow in the main water outlet can still be supplemented while the shower is in foaming mode.

[0060] Through the above technical solution, this utility model effectively solves the compatibility problem between multi-functional showers and gas water heaters. The foaming water valve core cavity 12 diverts water to the foaming water outlet 102 and the lower outlet 101 respectively, realizing dynamic replenishment of water flow. This structural arrangement ensures the continuous and stable operation of the gas equipment while guaranteeing the foaming water supply, and can adapt to low water pressure supply environments without the need for additional pressurization equipment.

[0061] Furthermore, the main body 1 is also provided with a lower water outlet chamber 141, a top spray water outlet chamber 142, a handheld shower water outlet chamber 143, a foaming water chamber 161, a foaming water outlet chamber 162, a flow distribution chamber 18, and a gas valve drain chamber 19.

[0062] The lower water outlet chamber 141 is connected to the water outlet end of the lower water outlet valve core chamber 111, the water outlet end of the gas valve drain chamber 19, and the lower water outlet 101, respectively.

[0063] The water inlet of the top spray water outlet chamber 142 is connected to the water outlet of the top spray valve core chamber 112, and the water outlet of the top spray water outlet chamber 142 is connected to the top spray water outlet 103.

[0064] The inlet end of the handheld shower head water outlet chamber 143 is connected to the outlet end of the handheld shower head valve core chamber 113, and the outlet end of the handheld shower head water outlet chamber 143 is connected to the handheld shower head water outlet 104.

[0065] The inlet end of the foaming water chamber 161 is connected to the outlet end of the foaming water valve core chamber 12, the outlet end of the foaming water chamber 161 is connected to the inlet end of the foaming water outlet chamber 162, the outlet end of the foaming water outlet chamber 162 is connected to the foaming water outlet 102, the outlet end of the foaming water chamber 161 is also connected to the inlet end of the flow distribution chamber 18, and the outlet end of the flow distribution chamber 18 is connected to the inlet end of the gas valve drain chamber 19.

[0066] The inlet end of the gas valve drain chamber 19 is connected to the outlet end of the gas valve core chamber 13.

[0067] Specifically, a control valve core is installed inside the lower outlet valve core cavity 111 to control the mutual connection or mutual closure of the inlet and outlet ends of the cavity. For example... Figure 9 As shown, when the control valve core of the lower outlet valve core cavity 111 is opened, water flows from the valve body inlet 100 into the inlet cavity 140, and then flows from the inlet cavity 140 through the inlet end of the lower outlet valve core cavity 111 into the lower outlet valve core cavity 111, and then flows out from the outlet end of the lower outlet valve core cavity 111 into the lower outlet cavity 141, and is discharged from the body 1 through the lower outlet 101.

[0068] Similarly, the water discharge principle of the top spray outlet 103 is as follows: water flows from the inlet chamber 140 into the diversion chamber 15, flows into the top spray valve core chamber 112 at one of the outlet ends of the diversion chamber 15, and flows out from the outlet end of the top spray valve core chamber 112 to the top spray outlet chamber 142, and then is discharged from the body 1 through the top spray outlet 103.

[0069] Similarly, the water outlet principle of the hand shower 104 is as follows: water flows from the inlet chamber 140 into the diversion chamber 15, flows into the hand shower valve core chamber 113 at one outlet end of the diversion chamber 15, and flows out from the outlet end of the hand shower valve core chamber 113 to the hand shower outlet chamber 143, and then is discharged from the body 1 through the hand shower outlet 104.

[0070] A control valve core is installed inside the gas valve core cavity 13 to control the interconnection or closure of the water inlet and outlet ends of the cavity. For example... Figure 8 As shown, the foaming water chamber 161 is connected to the foaming water outlet chamber 162, and also to the inlet end of the gas valve core chamber 13 via the flow distribution chamber 18. When the control valve core of the gas valve core chamber 13 is opened, water flows into the gas valve core chamber 13 from one outlet end of the diversion water chamber 15, and then flows from the outlet end of the gas valve core chamber 13 to the foaming water chamber 161. After flowing into the foaming water outlet chamber 162 from the outlet end of the foaming water chamber 161, it is discharged from the body 1 through the foaming water outlet 102. In addition, the water flows through the outlet end of the foaming water chamber 161, and then sequentially through the flow distribution chamber 18, the gas valve core chamber 13, and the gas valve drain chamber 19 before flowing into the lower outlet chamber 141 and being discharged from the body 1 through the lower outlet 101. The connection of the gas valve core cavity 13 allows part of the water flow that was diverted to the foaming function zone to flow back to the lower water outlet cavity 141 and be discharged from the lower water outlet 101, ensuring the foaming function of the shower while also meeting the flow threshold required for the ignition of the gas water heater.

[0071] Furthermore, the main body 1 is also provided with a flow distribution valve core cavity 17, which includes a foaming water inlet 170, a first diversion port 171 and a second diversion port 172. A flow distribution valve is provided inside the flow distribution valve core cavity 17, which is used to distribute the proportion of liquid flowing out from the first diversion port 171 and the second diversion port 172.

[0072] The foaming water inlet 170 is connected to the outlet of the foaming water chamber 161, the first diversion port 171 is connected to the inlet of the foaming water outlet chamber 162, the second diversion port 172 is connected to the inlet of the flow distribution chamber 18, and the foaming water outlet chamber 162 and the flow distribution chamber 18 are not connected to each other.

[0073] The flow distribution valve core cavity 17 refers to a chamber structure with three fluid channels, the internal space of which is used to install the flow regulation mechanism. The foaming water inlet 170 is connected to the outlet end of the foaming water chamber 161 and is used to receive the water flow delivered by the foaming water chamber 161. The first branch port 171 and the second branch port 172 refer to two independently set output ports, which are respectively connected to the foaming water outlet chamber 162 and the flow distribution cavity 18. The flow distribution valve is a device with proportional regulation function, which can be implemented by a rotary valve core or a slide valve structure. The rotation angle of the valve core can change the effective flow area of ​​the two branch ports.

[0074] Specifically, when water flows from the foaming water chamber 161 into the flow distribution valve core chamber 17 through the foaming water inlet 170, the rotary valve core adjusts the opening ratio of the first diversion port 171 and the second diversion port 172 according to a preset angle. For example, when the valve core rotates to 30°, the open area of ​​the first diversion port 171 accounts for 70% and the second diversion port 172 accounts for 30%. At this time, most of the water flows through the foaming water outlet chamber 162 to the foaming water outlet 102, satisfying the foaming function of the foaming component. The physical isolation design of the two diversion paths avoids mutual interference between water flows, and the real-time adjustment capability of the flow distribution valve enables the system to dynamically balance the functional water supply and the operating needs of the gas equipment.

[0075] Furthermore, the foaming water valve core cavity 12 includes a plurality of sub-foaming water valve core cavities 121, each sub-foaming water valve core cavity 121 is provided with the control valve core, the inlet end of the sub-foaming water valve core cavity 121 is connected to one outlet end of the drainage water cavity 15, and the outlet end of the sub-foaming water valve core cavity 121 is connected to the inlet end of the foaming water cavity 161.

[0076] Each of the sub-foaming water valve core cavities 121 is equipped with a corresponding control valve core. Different sub-foaming water valve core cavities 121 correspond to different bath products. By operating the control valve core of the corresponding sub-foaming water valve core cavity 121, water is passed through the sub-foaming water valve core cavity 121, and the corresponding bath product is input into the foaming component.

[0077] Furthermore, the lower water outlet valve core cavity 111, the top spray valve core cavity 112, the handheld shower valve core cavity 113 and a plurality of the sub-foaming water valve core cavities 121 are formed at the front end of the body 1, and the gas valve core cavity 13 and the flow distribution valve core cavity 17 are formed at the bottom of the body 1.

[0078] The valve body inlet 100 and the top spray outlet 103 are located at the top of the main body 1, the bottom outlet 101 is located at the bottom of the main body, and the handheld shower outlet 104 and the foaming water outlet 102 are located on the side of the main body 1 away from the valve body inlet 100.

[0079] The front end refers to the side of the main body closest to the operating interface, which can be achieved by machining a flat surface to create a valve core mounting groove, facilitating centralized maintenance of the valve core. The bottom refers to the lower end of the main body in the direction of gravity, which can be formed into a vertically extending cavity structure using casting technology to accelerate drainage using gravity. The top refers to the upper end of the main body in the direction of gravity, which can be provided with through holes to connect to external pipelines, ensuring stable high-level inlet pressure. The side furthest from the inlet refers to the distal area of ​​the main body perpendicular to the inlet axis, which can be isolated by a split-chamber design to avoid cross-interference of the water flow path.

[0080] Specifically, the lower water outlet valve core cavity 111, the top spray valve core cavity 112, and the handheld shower valve core cavity 113 (collectively referred to as the water purification valve core cavity) and the foaming water valve core cavity (several sub-foaming water valve core cavities 121) are centrally arranged at the front end to form a control module, reducing pressure loss caused by internal passage bends. Since the functions corresponding to the gas valve core cavity 13 and the flow distribution valve core cavity 17 are used less frequently in daily use, integrating the gas valve core cavity 13 and the flow distribution valve core cavity 17 at the bottom avoids accidental activation and makes the structure more compact. The valve body inlet 100 forms a high-level water inlet structure at the top, ensuring sufficient water pressure for the drainage chamber. The top spray outlet 103 is located at the top, facilitating connection to the shower head. The lower water outlet 101 forms a low-level water outlet channel at the bottom, utilizing potential energy difference to enhance water flow intensity. The handheld shower head outlet 104 and the foam water outlet 102 are arranged on the far side, and through spatial isolation, more functions can be integrated into the main body 1.

[0081] Furthermore, the foaming water outlet chamber 162, the flow distribution chamber 18, and the gas valve drain chamber 19 are formed on the top of the main body 1;

[0082] The water inlet chamber 140 and the water outlet chamber 15 are arranged horizontally along the left and right directions of the main body 1. The water outlet chamber 15 extends in the left and right directions. The lower water outlet chamber 141 is located behind the water inlet chamber 140. The top spray water outlet chamber 142 and the handheld shower water outlet chamber 143 are both located above the water outlet chamber 15. The foaming water chamber 161 is located behind the water outlet chamber 15.

[0083] The gas valve core cavity 13 and the flow distribution valve core cavity 17 extend in the vertical direction and are located on the rear side of the water diversion cavity 15.

[0084] By using a three-dimensional, layered layout, the main water flow channels, such as the inlet chamber 140 and the diversion chamber 15, are kept in a straight line, while the diversion functional cavities, such as the inlet chamber 140 and the diversion chamber 15, are independently arranged at different height levels, thus optimizing the internal structure of the water distribution device.

[0085] A shower device includes a housing, a solenoid valve 2, several liquid storage tanks 3, a liquid pump 4, a water inlet assembly 5, a foaming assembly, and the aforementioned water distribution device, wherein the solenoid valve 2, the liquid pump 4, the water inlet assembly 5, the foaming assembly, and the water distribution device are respectively disposed inside the housing;

[0086] The water inlet assembly 5 includes a cold water pipe 51, a hot water pipe 52, and a manifold 53. One end of the cold water pipe 51 and one end of the hot water pipe 52 are respectively connected to one end of the manifold 53, and the other end of the manifold 53 is connected to the valve body inlet 100.

[0087] The control valve core of the foaming water valve core cavity 12 is electrically connected to the solenoid valve 2. Several liquid storage tanks 3 are respectively connected to the input end of the solenoid valve 2. The output end of the solenoid valve 2 is connected to the input end of the liquid pump 4. The output end of the liquid pump 4 is connected to the feed end 701 of the foaming component. The liquid inlet end 702 of the foaming component is connected to the foaming water outlet 102. The foam outlet end 703 of the foaming component is connected to the handheld shower head outlet 104.

[0088] Solenoid valve 2 can be a two-position three-way solenoid valve to achieve multi-channel switching, selecting the shower liquid supply path of different storage tanks 3 through electrical control signals. Liquid pump 4 specifically adopts a peristaltic pump structure, used to quantitatively deliver shower liquid to the foaming component. The inlet end 702 of the foaming component is connected to the foaming water outlet 102 of the water distribution device, so that the foaming water flow and shower liquid form a premixed fluid in the mixing chamber of the foaming component. The control valve cores configured in the sub-foaming water valve core chamber 121 of the water distribution device are electrically connected to solenoid valve 2. When the corresponding control valve core is pressed, in addition to starting the corresponding sub-foaming water valve core chamber 121 to supply water to the foaming water chamber 161, the corresponding storage tank 3 is also driven to output shower liquid through solenoid valve 2.

[0089] Specifically, it includes two scenarios:

[0090] 1. When igniting the gas water heater, the foaming function is not used. At this time, the foaming water valve core chamber 12 of the water distribution device is in a closed state. Opening the control valve core of any sub-outlet valve core chamber enables water to be discharged while simultaneously igniting the gas water heater. At this time, all the water flowing into the water distribution device is output through the corresponding outlet (lower outlet 101, top spray outlet 103, or handheld shower outlet 104), ensuring that the drainage flow meets the ignition threshold of the gas equipment.

[0091] 2. When igniting the gas-fired water heater, the foaming function is used. When using the foaming function, the control valve core in the foaming water valve core cavity 12 is opened accordingly. After the water flows into the main body, it is divided into the foaming water cavity 161 and the foaming water outlet cavity 162, and output from the foaming water outlet 102. At this time, the water flow rate discharged through the lower outlet 101, the top spray outlet 103, or the handheld shower outlet 104 is reduced. In order to ensure the ignition requirements of the gas equipment, the control valve core in the gas valve core cavity 13 is opened to connect the "foaming water cavity 161-flow distribution cavity 18-gas valve drain cavity 19-lower outlet cavity 141" path, so that the water flows out from the lower outlet 101 to ensure the drainage flow rate threshold.

[0092] Furthermore, it also includes a water temperature control component 6, which is installed on the water inlet component 5 and is used to control the ratio of cold water and hot water entering the manifold 53.

[0093] The water temperature control component is installed on the water inlet component 5. After obtaining water at a suitable temperature by adjusting the hot and cold water mixing ratio, it is then delivered to the water distribution device.

[0094] Furthermore, it also includes an air pump 8, the output end of which is connected to the air inlet port 704 of the foaming assembly.

[0095] Specifically, the air pump 8 is connected to the air inlet port 704 of the foaming component to pump air into the foam liquid for mixing, which can make the foam richer. The foam liquid is output from the foam outlet 703 of the foaming component and merges with the water flow output from the hand shower outlet 104. Finally, the hand shower outputs the foam to provide the user, which can make the output foam richer and improve the user experience.

[0096] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
