It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 and 6, the embodiment of the present invention provides a shower head, which can convert water from a water supply pipe into a plurality of water jets with a certain pressure for the user to wash his body. The shower head of the present embodiment comprises a micro hydrogen production device 10, a shower head 20, a handle 40 and a control device 30, wherein the main bodies of the shower head 20 and the handle 40 can be made of plastic or metal shells, the shower head 20 is connected with the handle 40, and a water flow channel communicated with an external water supply pipeline is arranged in the handle 40.

The shower head 20 is provided with a first accommodating cavity 21 and a second accommodating cavity 22 which are separated from each other, and the first accommodating cavity 21 is communicated with the water flow passage of the handle 40, and because the first accommodating cavity 21 and the second accommodating cavity 22 are separated from each other, the water flow in the first accommodating cavity 21 can be prevented from entering the second accommodating cavity 22. The micro hydrogen production device 10 is arranged in the first accommodating cavity 21, the control device 30 is arranged in the second accommodating cavity 22, the micro hydrogen production device 10 is electrically connected with the control device 30, and the control device 30 controls the micro hydrogen production device to electrolyze water flowing into the first accommodating cavity 21 to generate hydrogen when detecting that water flow exists in the water flow channel (for example, the water pressure reaches a preset value); the side wall of the first accommodating cavity 21, which faces away from the second accommodating cavity 22, is provided with water spray holes, and water in which hydrogen generated by the micro hydrogen production device 10 is dissolved is sprayed out through the water spray holes. Namely, the micro hydrogen production device 10 is arranged in the shower head 20 and close to the water spraying holes on the shower head 20.

Because the diameter of shower head 20 is far greater than the diameter of handle 40, consequently can place the miniature hydrogen plant 10 that the volume is relatively great in shower head 20 to can improve the hydrogen content, and because miniature hydrogen plant 10 is nearer apart from the hole for water spraying, can avoid dissolving in the hydrogen of water and appear at the in-process that water flows to the water jet by miniature hydrogen plant 10, improve the hydrogen content in the play aquatic of shower.

As shown in fig. 2, which is a schematic view of an exploded structure of a micro hydrogen production device 10 in a shower head according to an embodiment of the present invention, the micro hydrogen production device includes a first electrode plate 11, a second electrode plate 12, a third electrode plate 13, a first partition plate 14, and a second partition plate 15. The first electrode plate 11, the second electrode plate 12, and the third electrode plate 13 are respectively in a sheet shape, and are made of conductive metal. For example, the main bodies of the first electrode plate 11, the second electrode plate 12 and the third electrode plate 13 may be respectively formed of circular titanium metal plates having a thickness of less than 2 mm and a diameter of 50-100 mm. Because titanium metal is relatively stable, no other ions enter water in the process of hydrogen production by electrolysis. Of the first electrode plate 11, the second electrode plate 12, and the third electrode plate 13, the surface of the electrode plate connected to the positive electrode of the power supply has a catalyst layer, and the catalyst layer may be specifically composed of a catalyst, etc., which can improve the hydrogen production efficiency.

In this embodiment, the first electrode plate 11, the second electrode plate 12, and the third electrode plate 13 are fixed together in parallel in sequence, the first electrode plate 11 and the third electrode plate 13 are connected to a first electrode of a voltage source, the second electrode plate 12 is connected to a second electrode of the voltage source, which is opposite to the first electrode, that is, during normal operation, the polarities of the first electrode plate 11 and the third electrode plate 13 are the same, and the polarity of the second electrode plate 12 is opposite to the polarities of the first electrode plate 11 and the third electrode plate 13. In an embodiment of the present invention, the first electrode may be a negative electrode of a voltage source, and the second electrode may be a positive electrode of the voltage source.

The first partition plate 14 is located between the first electrode plate 11 and the second electrode plate 12, and a first flow channel is formed between the first electrode plate 11 and the second electrode plate 12, that is, the first partition plate 14 is formed by plates perpendicular to the first electrode plate 11 and the second electrode plate 12, two side edges of the first partition plate 14 are respectively connected with the first electrode plate 11 and the second electrode plate 12 in a sealing manner, and the first flow channel is formed by enclosing the first partition plate 14, the first electrode plate 11 and the second electrode plate 12. The plane of the first flow channel is parallel to the first electrode plate 11 and the second electrode plate 12, that is, the water flow in the first flow channel flows in the plane parallel to the first electrode plate 11 and the second electrode plate 12, so that the water flow flowing in the first flow channel is always in contact with the first electrode plate 11 and the second electrode plate 12, and when the first electrode plate 11 and the second electrode plate 12 are electrified, hydrogen is generated by electrolysis under the action of voltage on the first electrode plate 11 and the second electrode plate 12, the hydrogen generated by electrolysis is soluble in water (the electrolysis can also generate oxygen at the same time, and the generated oxygen is also soluble in water), and the hydrogen content in water is improved.

The second partition 15 is located between the second electrode plate 12 and the third electrode plate 13, and a second flow channel is formed between the second electrode plate 12 and the third electrode plate 13, that is, the second partition 15 is formed by plates perpendicular to the second electrode plate 12 and the third electrode plate 13, two side edges of the second partition 15 are respectively connected with the second electrode plate 12 and the third electrode plate 13 in a sealing manner, and the second flow channel is formed by enclosing the second partition 15, the second electrode plate 12 and the third electrode plate 13. Similarly, the plane of the second flow channel is parallel to the second electrode plate 12 and the third electrode plate 13, that is, the water flow in the second flow channel flows in the plane parallel to the second electrode plate 12 and the third electrode plate 13, so that the water flow flowing in the second flow channel is always in contact with the second electrode plate 12 and the third electrode plate 13, and when the second electrode plate 12 and the third electrode plate 13 are powered on, hydrogen is generated by electrolysis under the action of voltage on the second electrode plate 12 and the third electrode plate 13, and the hydrogen generated by electrolysis is also soluble in water, thereby further increasing the hydrogen content in water.

In particular, the first separator 14 and the second separator 15 may be respectively made of an insulating elastic material, so that when the first separator 14 is disposed between the first electrode plate 11 and the second electrode plate 12 and the second separator 15 is disposed between the second electrode plate 12 and the third electrode plate 13, the first separator 14 is hermetically connected to the first electrode plate 11 and the second electrode plate 12, and the second separator 15 is hermetically connected to the second electrode plate 12 and the third electrode plate 13.

Or, the positions of the first separator 14 contacting the first electrode plate 11 and the second electrode plate 12 and the positions of the second separator contacting the second electrode plate 12 and the third electrode plate 13 may have elastic layers, respectively, which may also ensure that the first separator 14 is hermetically connected to the first electrode plate 11 and the second electrode plate 12, and the second separator 15 is hermetically connected to the second electrode plate 12 and the third electrode plate 13.

On the second electrode plate 12, there is also a through hole 121 communicating the first flow channel and the second flow channel, so that the water flowing through the first flow channel flows into the second flow channel through the through hole 121 and flows out through the second flow channel.

Through above-mentioned structure, get into miniature hydrogen plant's water, can form hydrogen and dissolve in water through first electrode board 11 and the electrolysis of second electrode board 12 earlier, then rethread second electrode board 12 and the further electrolysis of third electrode board 13 form hydrogen and dissolve in water, prolonged the stroke of single-stranded rivers between the electrode board, increased the contact stroke of single-stranded rivers and electrode board promptly, thereby can make the hydrogen that the electrode board produced dissolve in water more, greatly improve the hydrogen content in the aquatic.

In one embodiment of the present invention, the distance between the first electrode plate 11 and the second electrode plate 12 is 3-8 mm, which can ensure that the first electrode plate 11 and the second electrode plate 12 electrolyze the water in the first flow channel to generate hydrogen (the electrolysis also generates oxygen, and the generated oxygen is also dissolved in the water). Similarly, the distance between the second electrode plate 12 and the third electrode plate 13 is 3-8 mm.

As shown in fig. 4, in an embodiment of the present invention, the through hole 121 is located at a center position of the second electrode plate 12, for example, when the second electrode plate 12 is circular, the through hole 121 is located at a center of the circle. Accordingly, the first flow channel is spiral around the central axis of the through hole 121, that is, the cross section of the first partition plate 14 is spiral, the water inlet of the first flow channel is located at the outer edge of the spiral, the water outlet of the first flow channel is formed by the through hole 121, and as shown in fig. 5, water entering from the outer edge of the spiral flows to the center of the spiral and enters the through hole 121 under the guidance of the spiral first flow channel. Because the first flow channel adopts the spiral shape, on one hand, the length of the first flow channel can be prolonged, and the contact length of the water flow with the first electrode plate 11 and the second electrode plate 12 is increased, so that the content of hydrogen dissolved in the water flow is increased, on the other hand, the first partition plate 14 can not block the water flow, and the water in the first flow channel can be ensured to flow smoothly.

Similarly, the second flow channel is spiral around the central axis of the through hole 121, i.e. the cross section of the second partition 15 is spiral. The water inlet of the second flow channel is formed by a through hole 121, and the water outlet 152 of the second flow channel is located at the outer edge of the spiral shape, so that the water flowing in from the through hole 121 flows to the spiral edge and flows out under the guidance of the spiral second flow channel. Because the second flow channel adopts a spiral shape, on one hand, the length of the second flow channel can be prolonged, and the contact length of the water flow with the second electrode plate 12 and the third electrode plate 13 is increased, so that the content of hydrogen dissolved in the water flow is increased, on the other hand, the second baffle plate 15 can not block the water flow, and the smooth flow of the water in the second flow channel can be ensured.

In a specific implementation, the first flow channel and the second flow channel may be both spiral, or one of them may be spiral and the other may be in other shapes. Experiments prove that when the first flow passage and the second flow passage are simultaneously spiral, the content of hydrogen in the effluent is improved by 30-40% compared with the content of hydrogen in the effluent adopting a common single-flow-passage hydrogen production device under the same conditions (namely the same energy consumption) under the condition of the same effluent flow.

The edges of the first electrode plate 11, the second electrode plate 12, and the third electrode plate 13 may respectively have a plurality of fixing

holes

111, 122, and 131 distributed along the circumferential direction, and the first electrode plate 11, the second electrode plate 12, and the third electrode plate 13 are fixed together by bolts 16 passing through the fixing

holes

111, 122, and 131, respectively, to form an electrolysis module. The bolt 16 may be made of an insulating material, or an insulating washer or a snap ring may be disposed at a portion (i.e., the fixing

hole

111, 122, 131) of the first electrode plate 11, the second electrode plate 12, or the third electrode plate 13, which is in contact with the bolt 16, so as to prevent the bolt 16 from being electrically connected to the first electrode plate 11, the second electrode plate 12, or the third electrode plate 13. In practical applications, the first partition 14 and the second partition 15 may also have fixing

holes

141, 151, respectively, so that the bolts 16 can fix the first partition 14 and the second partition 15 at the same time to prevent the first partition 14 and the second partition 15 from being displaced. Of course, in practical applications, the first electrode plate 11, the second electrode plate 12, the third electrode plate 13, the first separator 14, and the second separator 15 may be fixed by other methods.

The control device 30 may specifically include a battery 31 (the battery 31 may be a rechargeable battery) disposed in the second receiving cavity 22 and a first control circuit board 32, wherein the first control circuit board 32 is powered by the battery 31, and the first control circuit board 32 outputs a direct current of 1 to 4A to the electrolysis module (i.e., the first electrode plate 11, the second electrode plate 12, and the third electrode plate 13) through a conductive terminal or a conductive wire extending to the first receiving cavity 21. Specifically, referring to fig. 3, the battery 31 can provide a dc voltage of 5V, and the first control circuit board 32 can boost the dc voltage of 5V output from the battery 31 to dc voltage of 6.5V by the battery voltage processing circuit, which includes the voltage management chip IC1 and the boost circuit IC2, as shown in fig. 5. Referring to fig. 4, the first control circuit board 32 may further include a dc-to-dc unit for processing the 6.5V dc to form a required output current and supplying power to the electrode plate of the micro hydrogen production apparatus 10. The specific structure of the battery voltage processing circuit and the dc-dc conversion unit on the first control circuit board 32 is conventional in the art and will not be described herein.

In addition, still can set up the power supply interface on gondola water faucet head 20, for example voltage is 5V's TYPE-C interface or USB interface etc. and this power supply interface and voltage management chip IC 1's voltage input end lug connection can make gondola water faucet head 20 sustainable work through the power supply interface, avoids battery 31 electric quantity to exhaust and leads to miniature hydrogen plant can't generate hydrogen. Of course, the first control circuit board 32 may further include a charging circuit, which is connected to both the power supply interface and the battery 31, and converts the output of the power supply interface into a charging current, thereby charging the battery 31. The charging circuit may adopt a conventional circuit structure, and is not described herein again.

In order to improve the waterproof performance, the power supply interface may be replaced with a power receiving coil, and accordingly, an external power supply terminal has a power transmitting coil, so that the first control circuit board 32 can be wirelessly supplied with power and the battery 31 can be wirelessly charged.

As shown in connection with fig. 6-7, in one embodiment of the present invention, the shower head 20 includes a water inlet 142 communicating with the first receiving chamber 21, the handle 40 includes a first connector 41 for connecting to a water supply pipe, a second connector 42 for connecting to the shower head 20, and a water flow passage 43 extending from the first connector 41 to the second connector 42, and the handle 40 is detachably assembled to the water inlet 142 of the shower head 20 through the second connector 42, so that water from the water supply pipe can enter the first receiving chamber 21 of the shower head 20 through the water flow passage 43 in the handle 40. That is, the grip 40 is detachably connected to the shower head 20 so that the user can easily replace the grip to meet different use requirements. Specifically, the shape and structure of the shower head 20 and the handle 40 are similar to those of a conventional shower head, and the second joint 42 and the water inlet 142 can be connected by a screw structure, a snap structure, or the like, without limitation.

In this embodiment, the grip 40 further includes a water filtering component 44, and the water filtering component 44 is located in the water flow channel 43, so that the water flowing into the water flow channel 43 from the first joint 41 flows through the water filtering component 44 and then flows out from the second joint 42. In this manner, the water filtering assembly 44 may filter the flow of water entering the grip 40. In particular, the water filtering component 44 may be one of a water purification unit, a water softening unit, and a different fragrance release unit, etc., i.e., different grips 40 may be provided with different water filtering components 44, so that water flowing therethrough may be treated differently. For example, the water purification unit can adopt medical stone particles and/or pumice particles and the like, which can adsorb impurities in water through adsorption and release trace elements into the water; the water softening unit can adopt resin particles and the like, and can exchange with calcium ions and magnesium ions in water through functional ions on the resin particles so as to adsorb redundant calcium ions and magnesium ions in the water and realize water softening; the fragrance releasing unit can adopt particles containing fragrance components, so that the fragrance is released into water when water flows through the particles, and the effects of relieving fatigue and the like can be achieved. The water filtering assembly 44 may be of any conventional type and construction and will not be described in detail herein.

In particular, two metal screens 45 are provided within the water flow channel 43, the water filter assembly 44 being located between the two metal screens 45. The two metal screens 45 primarily prevent larger solid particles from the water supply pipe and prevent solid particles from the water filter assembly 44 from entering the shower head 20.

The second connector 42 is provided with a first electrical connector 421 and a marking 422 corresponding to the type of the water filtering assembly 44. Since different grips 40 contain different types of water filtering elements 44, the marking portions 422 thereof also have different properties, that is, the information of the water filtering elements 44 contained in the grips 40 is recorded in the marking portions 422, and the types of the water filtering elements 44 contained in the grips 40 can be known by acquiring the marking information of the marking portions 422.

Accordingly, the water inlet interface 142 includes a second electrical connector (not shown in the drawings) electrically connected to the first control circuit board 32, and the first electrical connector 421 is electrically connected to the first control circuit board 32 via the second electrical connector when the second connector 42 is fitted to the water inlet interface 142. In this way, the first control circuit board 32 can obtain the marking information of the marking portion 422 through the second connector and the first connector 421, that is, know the type of the water filtering component 44 included in the handle 40 connected to the shower head 20, so that the first control circuit board 32 can enable the micro hydrogen production apparatus to operate in different modes according to the type of the water filtering component 44. For example, when the first control circuit board 32 knows that the water filtering component 44 in the handle 40 is a fragrance releasing unit, the micro hydrogen production device 10 is controlled to stop working, so as to avoid damaging fragrance molecules in the hydrogen production process by electrolysis; when the first control circuit board 32 knows that the water filtering component 44 in the handle 40 is a water purifying unit or a water softening unit, the micro hydrogen production device 10 is controlled to work at a rated power, so that the hydrogen content of the outlet water of the shower head 20 is higher.

By arranging the water filtering component 44 in the water flow channel 43 of the handle 40 and arranging the marking part 422 for the first control circuit board 32 in the shower head 20 to read at the connecting position of the handle 40 and the shower head 20, the shower head can adjust the working mode according to the type of the water filtering component, thereby meeting different requirements of users.

In practical use, the first control circuit board 32 can obtain the marking information of the marking part 422 by other means besides the first electrical connector 421 and the second electrical connector. For example, the marking portion 422 may be an NFC tag or an RFID tag, and the first control circuit board 32 has a corresponding tag reading circuit, but this will increase the overall cost of the shower head.

In an embodiment of the present invention, when the first control circuit board 32 obtains the mark information of the mark portion 422 through the first electrical connector 421 and the second electrical connector, the mark portion 422 is composed of a flexible conductive material located in the water flow channel 43 and having a predetermined resistivity, and accordingly, the first control circuit board 32 includes the detection circuit 221 for detecting the resistance (voltage), that is, the mark information of the mark portion 422 is composed of different resistance values, and the first control circuit board 32 learns the type of the corresponding water filtering component 44 in the handle 40 by detecting the resistance value of the mark portion 422. When the second connector 42 is fitted to the water inlet interface 142, the first electrical connector 421 is electrically connected to the detection circuit via the second electrical connector. The marking portion 422 can contact with the first electrical connector 421 under the action of the water flow pressure in the water flow passage 43, and is electrically connected to the first control circuit board 32 through the first electrical connector 421 and the second electrical connector. That is, the first control circuit board 32 acquires the marking information from the marking part 422 of the grip 40 when the water supply pipe is opened and supplies water to the shower head; and the first control circuit board 32 does not acquire the marking information when the water supply pipe is not opened. In this way, the power consumption of the first control circuit board 32 can be saved.

In a specific implementation, as shown in fig. 8, the inner wall of the second contact 42 may have a groove, the first electrical connector 421 includes at least two first conductive portions D1 located at the outer periphery of the second contact 42 and at least two second conductive portions D2 located at the bottom of the groove, and each of the first conductive portions D1 is electrically connected to one of the second conductive portions D2. Accordingly, the indicia 422 are formed of an elastic rubber membrane incorporating a conductive medium, with different types of water filter elements 44 having differing amounts of conductive medium incorporated into the indicia 422, thereby exhibiting different electrical resistivities. The marker 422 (i.e., the elastic rubber film doped with the conductive medium) is fixed at the opening of the groove and seals the groove (waterproofing of the second conductive part is achieved), and the marker 422 is pushed toward the bottom of the groove and contacts the second conductive part D2 at the bottom of the groove when it is pressurized by the water flow, thereby forming a path between the two first conductive parts D1 (the elastic rubber film doped with the conductive medium can be abstracted as the resistance Rs). That is, when the second connector 42 is assembled to the water inlet 142, the marking portion 422 is electrically connected to the detection circuit via the first electrical connector 421 and the second electrical connector to form a loop, which can also serve as a detection signal for water in the water flow channel 43, and the first control circuit board 32 can control the micro hydrogen production device to start producing hydrogen according to the signal.

Specifically, each second conductive portion is constituted by at least one first metal contact exposed to the outer periphery of the second tab 42; alternatively, each first conductive portion is constituted by a first metal ring surrounding the outer periphery of the second tab 42. Similarly, each second conductive part is composed of at least one second metal contact exposed out of the bottom wall of the groove and electrically connected with the same first conductive part; or each second conductive part is formed by a second metal ring which is exposed out of the bottom wall of the groove and electrically connected with one first conductive part. For example, when the main body of the grip 40 is made of a non-conductive material such as plastic, the first electrical connection member may be formed by a metal sheet or a metal strip that is integrally injection-molded with the main body of the grip 40, and both ends of the metal sheet or the metal strip are exposed to the outer periphery of the main body of the grip 40 and the bottom wall of the groove, respectively.

Accordingly, as shown in fig. 9, the first control circuit board 32 may include a main control unit, an electrolysis driving unit, a status display unit, a time counting unit, a handle function detecting unit, a start detecting unit, and the like, wherein the electrolysis driving unit may be specifically implemented in combination with the circuit of fig. 4. The grip function detecting unit and the start detecting unit can be realized by combining the circuits in the dashed line frame in fig. 8. As described in connection with fig. 4, when the grip function detecting unit and the start detecting unit detect that water flows enter, the main control unit sends an enable signal to the dc-dc converter circuit according to a preset control logic (for example, the water filtering component 44 is a water purifying unit) to enable the electrolysis driving unit to output current to the electrode plate of the micro hydrogen production apparatus 10, and meanwhile, the state display unit can indicate the working state of the micro hydrogen production apparatus 10 through the indicator light; the time counting unit starts timing and accumulates the working time of the micro hydrogen production device 10 and the water filtering component 44 (provides reference for replacing the water filtering component 44 and the micro hydrogen production device 10).

The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
