Description

Technical Field

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

[0002] As people's living standards improve, their demands for the bathing experience also increase. Some existing showerheads allow shower gel or shampoo to be added directly to the water pipes connected to the shower head, mixing shower gel foam into the water sprayed from the shower head, making it more convenient for users to use shower gel or shampoo while showering. However, due to inconsistent water pressure in each household, especially in high-rise buildings and self-built houses where the water pressure is low, the automatic force of the tap water cannot achieve the desired mixing and foaming, resulting in unstable foam output from the showerhead. Therefore, showerheads often need to be equipped with independent liquid pumps, which increases production costs and the potential for malfunctions. Utility Model Content

[0003] Therefore, it is necessary to provide a shower device that addresses the problem of unstable water pressure in some existing shower devices, which prevents the automatic mixing and foaming of tap water and results in unstable bubble output.

[0004] A shower device includes a liquid storage bottle, a foaming unit, and a liquid inlet assembly. The liquid inlet assembly includes a water inlet pipe, a water pump, and a venturi tube. The water inlet pipe is connected to the water inlet end of the water pump. The venturi tube has a first liquid inlet, a second liquid inlet, and a first liquid outlet. The first liquid inlet is connected to the water outlet end of the water pump, and the second liquid inlet is connected to the liquid storage bottle. The foaming unit has a foaming chamber and an input port and an output port respectively communicating with the foaming chamber. The first liquid outlet is connected to the input port, and the output port is used to output the foam liquid in the foaming chamber.

[0005] This application provides a shower unit equipped with a water pump to provide power for clean water. The pump's outlet and a storage bottle are connected to the first and second inlets of a venturi tube, respectively. When clean water flows at high speed through the throat of the venturi tube, according to Bernoulli's principle, the pressure drops sharply, creating a vacuum and generating a strong suction effect. This allows the cleaning liquid in the storage bottle to be automatically drawn in. Finally, the energy provided by the pump, along with the mixture of the drawn-in clean water and cleaning liquid, enters the foaming unit through the venturi tube's outlet for further foaming to form a foam liquid. This device, utilizing the combination of a water pump and a venturi tube, not only maintains stable water pressure in the shower unit but also allows for the simultaneous extraction of both clean water and cleaning liquid with a single pump. This simplifies the electrical structure, effectively reduces production costs, and lowers the risk of device failure.

[0006] In one embodiment, a switching pipeline is also included, comprising a three-way switching valve and an outlet pipe. The first port of the three-way switching valve is connected to the inlet pipe, the second port is connected to the inlet of the water pump, and the third port is connected to the outlet pipe. By adopting this structure, users can easily switch between the foam liquid path and the clean water path as needed using the three-way switching valve. When foam generation is required, clean water flows sequentially through the inlet pipe, the first port, and the second port to the water pump, where it enters the foaming unit under the pump's driving force and mixes with the cleaning liquid to generate foam liquid. When foam generation is not required, the user operates the three-way switching valve to connect the first and third ports, allowing clean water to flow through the inlet pipe into the three-way switching valve and then out through the outlet pipe, achieving the effect of showering or rinsing.

[0007] In one embodiment, the foaming unit is provided with a liquid passage chamber, one end of which is connected to the output port, and the other end of which is provided with a liquid passage hole. The end of the water outlet pipe away from the three-way switching valve is connected to the liquid passage chamber through the liquid passage hole. By adopting the above structure, the clean water discharged from the water outlet pipe will be discharged through the output port of the foaming unit, which facilitates the high integration of the liquid inlet component, switching pipeline, and foaming unit into a compact module, not only simplifying the system layout but also effectively reducing the risk of leakage.

[0008] In one embodiment, the foaming chamber is connected to the outlet via the liquid-passing chamber, which is located below the foaming chamber. This allows clean water to maintain a distance from the foaming chamber and the foaming components within it after entering the liquid-passing chamber through the liquid hole, thus better preserving the water's purity.

[0009] In one embodiment, a microswitch and a control circuit board are also included. The control circuit board is connected to the water pump and used to control the pump's start and stop. The microswitch is connected to the control circuit board and is configured to be triggered by the three-way switching valve to send a start signal to the control circuit board. With this structure, when the user turns the three-way switching valve to the foaming mode, the valve simultaneously triggers the microswitch activation circuit, causing the water pump / air pump, etc., to start operating.

[0010] In one embodiment, the foaming unit includes a housing assembly and a foaming assembly. The housing assembly has the foaming cavity, and the foaming assembly is disposed within the foaming cavity. The foaming assembly is used to transform the mixture entering the foaming cavity into foam. By embedding the foaming assembly within the foaming cavity, when the mixture of water and cleaning fluid flows through the foaming cavity, the porous structure of the foaming assembly cuts, squeezes, and permeates the liquid, efficiently transforming the mixture into uniform and fine foam, achieving a low-energy-consumption and high-stability foam generation effect.

[0011] In one embodiment, the housing assembly includes an outer shell and a mounting cylinder. The outer shell has the foaming cavity, the inlet, and the outlet. The mounting cylinder is disposed in the foaming cavity and has mounting holes. The inlet communicates with the outlet through the mounting holes. The foaming assembly includes multiple foaming meshes, each of which is fitted and installed to fit the mounting holes and spaced axially along the mounting holes. By adopting the above structure, the multiple foaming meshes spaced axially along the mounting holes form a multi-stage foaming channel, thereby allowing the mixture to be cut, squeezed, and permeated multiple times, greatly improving the fineness and uniformity of the foam.

[0012] In one embodiment, the mounting cylinder is connected to the side of the mounting cylinder with the inlet, and the mounting hole is positioned opposite to the inlet. By adopting the above structure, the mounting cylinder is directly connected to and aligned with the inlet, thereby allowing the liquid entering the foaming chamber through the inlet to fully, smoothly, and directly impact the foaming net, which can improve foaming efficiency and foam quality.

[0013] In one embodiment, the foaming unit further includes a sealing ring fitted over the outer side of the mounting cylinder. The sealing ring seals the connection gap between the mounting cylinder and the inner wall of the foaming chamber. Simultaneously, the reliable sealing of the gap between the mounting cylinder and the chamber wall by the sealing ring ensures that all the mixture can fully pass through the multi-stage foaming mesh.

[0014] In one embodiment, an air pump is also included, the air outlet of which is connected to the foaming chamber. The air pump supplies air to the foaming unit. The air pump, connected to the foaming chamber, pumps gas into the foam liquid within the chamber for mixing, resulting in richer foam. The foam liquid is then output from the outlet to a shower head or similar device to provide foam to the user, thus enhancing the user experience and producing richer foam.

[0015] In one embodiment, a tee connector is further included. The tee connector has a fluid channel and includes a first axial connector portion, a second axial connector portion, and a radial connector portion, each communicating with the fluid channel. One end of the radial connector portion is connected to one of the air pump and the first liquid outlet. The other end of the radial connector portion extends into the fluid channel and extends away from the first axial connector portion along its axial direction. The first axial connector portion is connected to the other of the air pump and the first liquid outlet. The second axial connector portion is connected to the inlet. By employing this structure, the end of the radial connector portion extending into the fluid channel extends away from the first axial connector portion along its axial direction, thereby preventing the gas input from the air pump from colliding with the mixed liquid input from the venturi tube, and reducing the impact of the airflow on the fluid flow within the venturi tube.

[0016] In one embodiment, the venturi tube is provided with a second liquid outlet, and the second liquid outlet is equipped with a drain valve. By providing the drain valve, the second liquid outlet can be opened to drain water during foaming, which helps to stabilize the total water pressure and the ratio of hot to cold water, ensuring that the gas water heater will not shut off.

[0017] In one embodiment, a first flow regulating valve is also included, which is disposed on the water inlet pipe. This allows for convenient adjustment of the water flow rate of the showerhead and the regulation of the proportion of clean water in the foam solution.

[0018] In one embodiment, a second flow regulating valve is further included, which is connected between the second inlet and the storage bottle. This allows for the adjustment of the cleaning solution ratio in the foam solution.

[0019] In one embodiment, the number of liquid storage bottles is no less than two, and these two liquid storage bottles are selectively connected to the second liquid inlet via a multi-way valve. Specifically, when there is more than one liquid storage bottle, the cleaning fluid channel of multiple liquid storage bottles can be switched manually by operating the multi-way valve, reducing the use of circuit components.

[0034] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0036] The following describes some embodiments of the shower device according to the present invention with reference to the accompanying drawings.

[0037] like Figures 1 to 6As shown, this embodiment discloses a shower device, including a liquid storage bottle 1, a foaming unit 2, and a liquid inlet assembly 3. The liquid inlet assembly 3 includes a water inlet pipe 31, a water pump 32, and a venturi tube 33. The water inlet pipe 31 is connected to the water inlet end of the water pump 32. The venturi tube 33 is provided with a first liquid inlet 301, a second liquid inlet 302, and a first liquid outlet 303. The first liquid inlet 301 is connected to the water outlet end of the water pump 32, and the second liquid inlet 302 is connected to the liquid storage bottle 1. The foaming unit 2 is provided with a foaming chamber 201 and an input port 202 and an output port 203 respectively connected to the foaming chamber 201. The first liquid outlet 303 is connected to the input port 202, and the output port 203 is used to output the foam liquid in the foaming chamber 201.

[0038] This application provides a shower device equipped with a water pump 32 to provide a power source for clean water. The outlet of the water pump 32 and the storage bottle 1 are connected to the first inlet 301 and the second inlet 302 of a venturi tube 33, respectively. When clean water flows at high speed through the throat of the venturi tube 33, according to Bernoulli's principle, the pressure drops sharply, creating a vacuum and generating a strong suction effect. This allows the cleaning liquid in the storage bottle 1 to be automatically drawn in. Finally, the energy provided by the water pump 32 and the mixture of the drawn-in clean water and cleaning liquid enter the foaming unit 2 through the outlet 203 of the venturi tube 33 for further foaming to form a foam liquid. This device, utilizing the cooperation of the water pump 32 and the venturi tube 33, not only maintains stable water pressure in the shower device but also allows for the simultaneous extraction of both clean water and cleaning liquid with a single pump 32. This simplifies the electrical structure of the device, effectively reduces production costs, and lowers the risk of device failure.

[0039] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further includes a switching pipeline 4, which comprises a three-way switching valve 41 and an outlet pipe 42. The first valve port of the three-way switching valve 41 is connected to the inlet pipe 31, the second valve port of the three-way switching valve 41 is connected to the inlet end of the water pump 32, and the third valve port of the three-way switching valve 41 is connected to the outlet pipe 42. By adopting the above structure, users can conveniently switch between the foam liquid water path and the clean water path using the three-way switching valve 41 as needed. When foam needs to be generated, clean water flows sequentially through the inlet pipe 31, the first valve port, and the second valve port to the water pump 32, and enters the foaming unit 2 under the driving force of the water pump 32 to mix with the cleaning liquid to generate foam liquid. When foaming is not required, the user operates the three-way switching valve 41 to connect the first valve port and the third valve port, so that clean water flows through the inlet pipe 31 into the three-way switching valve 41 and then flows to the outlet pipe 42 for discharge, achieving the effect of showering or rinsing.

[0040] like Figure 2 , Figure 5 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the foaming unit 2 is provided with a liquid passage chamber 204, one end of which is connected to the output port 203, and the other end of which is provided with a liquid passage hole 205. The end of the water outlet pipe 42 away from the three-way switching valve 41 is connected to the liquid passage chamber 204 through the liquid passage hole 205. By adopting the above structure, the clean water discharged from the water outlet pipe 42 will be discharged through the output port 203 of the foaming unit 2, which facilitates the high integration of the liquid inlet assembly 3, the switching pipeline 4, and the foaming unit 2 into a compact module, which not only simplifies the system layout but also effectively reduces the risk of leakage.

[0041] like Figure 5 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the foaming chamber 201 is connected to the outlet 203 through the liquid passage chamber 204, and the liquid passage chamber 204 is located below the foaming chamber 201. Therefore, when clean water enters the liquid passage chamber 204 through the liquid hole 205, it can maintain a distance from the foaming chamber 201 and the foaming component 22 in the foaming chamber 201, allowing the clean water to remain cleaner.

[0042] In addition to the features of the above embodiments, this embodiment further includes a micro switch and a control circuit board. The control circuit board is connected to the water pump 32 and is used to control the start and stop of the water pump 32. The micro switch is connected to the control circuit board and is configured to be triggered by the three-way switching valve 41 to send a start signal to the control circuit board. By adopting the above structure, when the user turns the three-way switching valve 41 to switch to the foaming mode, the three-way switching valve 41 will simultaneously trigger the micro switch activation circuit, causing the water pump 32 / air pump 5, etc., to start working.

[0043] like Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the foaming unit 2 includes a housing assembly 21 and a foaming assembly 22. The housing assembly 21 is provided with a foaming cavity 201, and the foaming assembly 22 is disposed in the foaming cavity 201. The foaming assembly 22 is used to transform the mixture entering the foaming cavity 201 into foam. By embedding the foaming assembly 22 in the foaming cavity 201, when the mixture of clean water and cleaning liquid flows through the foaming cavity 201, the porous structure of the foaming assembly 22 cuts, squeezes, and permeates the liquid, efficiently transforming the mixture into uniform and fine foam, achieving a low-energy consumption and high-stability foam generation effect.

[0044] like Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 21 includes a housing 211 and a mounting cylinder 212. The housing 211 is provided with a foaming cavity 201, an inlet 202, and an outlet 203. The mounting cylinder 212 is disposed in the foaming cavity 201 and is provided with a mounting hole 206. The inlet 202 communicates with the outlet 203 through the mounting hole 206. The foaming assembly 22 includes multiple foaming nets, and the multiple foaming assemblies 22 are all adapted to be installed in the mounting hole 206 and are spaced apart along the axial direction of the mounting hole 206. By adopting the above structure, the multiple foaming nets are spaced apart along the axial direction of the mounting hole 206, thereby forming a multi-stage foaming channel. As a result, the mixture will be cut, squeezed, and permeated multiple times, which greatly improves the fineness and uniformity of the foam.

[0045] like Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the mounting cylinder 212 is connected to the side of the mounting cylinder 212 with the inlet 202, and the mounting hole 206 is arranged opposite to the inlet 202. By adopting the above structure, the mounting cylinder 212 is directly connected to the side with the inlet 202 and aligned with the inlet 202, thereby allowing the liquid entering the foaming chamber 201 through the inlet 202 to fully, smoothly and directly impact the foaming net, which can improve the foaming efficiency and foam quality.

[0046] like Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the foaming unit 2 also includes a sealing ring 23, which is sleeved on the outside of the mounting cylinder 212 and is used to seal the connection gap between the mounting cylinder 212 and the inner wall of the foaming cavity 201. Simultaneously, the reliable sealing of the gap between the mounting cylinder 212 and the cavity wall by the sealing ring 23 ensures that all the mixture can fully pass through the multi-stage foaming mesh.

[0047] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further includes an air pump 5. The air outlet of the air pump 5 is connected to the foaming chamber 201, and the air pump 5 is used to supply air to the foaming unit 2. The air pump 5 is connected to the foaming chamber 201, pumping air into the foam liquid in the foaming chamber 201 for mixing, which can make the foam richer. The foam liquid is output from the output port 203, and finally output to the shower head, etc. to provide foam to the user, which can make the output foam richer and improve the user experience.

[0048] like Figure 2 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further includes a three-way connector 6. The three-way connector 6 is provided with a fluid channel. The three-way connector 6 includes a first axial connector portion 61, a second axial connector portion 62, and a radial connector portion 63, which are respectively connected to the fluid channel. One end of the radial connector portion 63 is connected to one of the air pump 5 and the first liquid outlet 303. The other end of the radial connector portion 63 extends into the fluid channel and extends away from the first axial connector portion 61 along its axial direction. The first axial connector portion 61 is connected to the other of the air pump 5 and the first liquid outlet 303. The second axial connector portion 62 is connected to the inlet 202. By adopting the above structure, the end of the radial connector portion 63 that extends into the fluid channel extends away from the first axial connector portion 61 along its axial direction. This avoids the gas input from the air pump 5 from clashing with the mixed liquid input from the venturi tube 33, reducing the influence of the airflow on the fluid flow inside the venturi tube 33.

[0049] like Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the venturi tube 33 is provided with a second liquid outlet 304, and the second liquid outlet 304 is provided with a drain valve 34. By setting the drain valve 34, the drain valve 34 can be operated to open the second liquid outlet 304 to drain water during foaming, which helps to stabilize the total water pressure and the ratio of hot and cold water, ensuring that the gas water heater will not shut off.

[0050] In addition to the features of the above embodiments, this embodiment further includes a first flow regulating valve, which is disposed on the water inlet pipe 31. This allows for convenient adjustment of the water output of the shower head and the regulation of the proportion of clean water in the foam solution via the first flow regulating valve.

[0051] like Figure 1 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further includes a second flow regulating valve 7, which is connected between the second inlet 302 and the storage bottle 1. Thus, the proportion of cleaning liquid in the foam liquid can be adjusted via the second flow regulating valve 7.

[0052] In addition to the features of the above embodiments, this embodiment further specifies that: the number of liquid storage bottles 1 is not less than two, and the not less than two liquid storage bottles 1 are selectively connected to the second liquid inlet 302 through a multi-way valve. Specifically, when there is more than one liquid storage bottle 1, the multiple liquid storage bottles 1 can switch the cleaning fluid channel by manually operating the multi-way valve, reducing the use of circuit components.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
