Description

Technical Field

[0001] This utility model belongs to the field of bathroom technology and relates to a shower head. Background Technology

[0002] Showerheads are very common bathroom products, mainly used by users during daily bathing. Traditional showerheads do not have a temperature display function, and users are prone to scalding themselves by not being able to check the water temperature in time when turning them on. To address this, Chinese patent application number 202320392336.1 discloses a digital display showerhead handle, which includes a housing, a pressing component, a digital display component, and a connector. One end of the housing is a water inlet, and the other end is a water outlet for connecting to the showerhead. A water flow channel is formed inside the housing. The digital display component is mounted on the housing to display the temperature of the water in the water flow channel. The pressing component is mounted on the housing, and pressing the pressing component opens or closes the water flow channel. One end of the connector is connected to the water inlet and abuts against the digital display component to restrict the digital display component, and the other end of the connector is used to connect to the water inlet pipe. The digital display component includes a water generator and a digital display screen. The water generator is located inside the water flow channel and has a temperature sensing element. The digital display screen is mounted on the housing and is connected to the water generator via a connecting wire to display the water temperature. During use, water from the inlet pipe enters the water flow channel through the connector. The water in the water flow channel drives the impeller inside the hydroelectric generator to rotate, generating electricity to power the digital display screen. At the same time, the temperature sensing element on the hydroelectric generator detects the water temperature and displays it on the digital display screen, allowing users to easily monitor the water temperature and adjust it in time to prevent the water from becoming too hot or too cold.

[0003] However, the aforementioned digital display shower handle also has its shortcomings: during assembly, the digital display screen and the water generator are installed separately in the housing. In particular, the digital display screen is set in the second mounting cavity of the housing, and the housing is tubular with a relatively small internal space. This makes it very inconvenient to thread and connect the water generator and the digital display screen with connecting wires inside the housing, thus causing assembly inconvenience. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a shower head that solves the inconvenience of assembly and maintenance.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A shower head includes a handle and a shower head detachably connected to the front end of the handle. The handle contains a digital display module and a water generator, which are electrically connected. The handle contains a water-passing assembly with a flow channel. The water generator is fixed within the flow channel, and the digital display module is fixed to the side of the water-passing assembly. A limiting step is provided at the rear end of the handle. A raised edge is provided on the outer side of the rear end of the water-passing assembly, abutting against the limiting step. The front end of the water-passing assembly has a columnar water outlet located within the front end of the handle. A limiting cap is externally threaded onto the water outlet. A shoulder is provided within the front end of the handle, and the rear end of the limiting cap abuts against the shoulder.

[0007] During assembly, first fix the hydroelectric generator inside the flow channel of the water-passing assembly, and fix the digital display module to the side of the water-passing assembly. Then, insert the water-passing assembly into the handle from back to front. The outer protrusion of the rear end of the water-passing assembly will abut against the limiting step inside the rear end of the handle, while the water outlet of the front end of the water-passing assembly will extend into the front end of the handle. Then, thread the limiting cap to the outside of the water outlet and abut against the shoulder inside the front end of the handle. In this way, the water-passing assembly can be fixed inside the handle by the abutment between the protrusion and the limiting step, and the abutment between the limiting cap and the shoulder. By incorporating a water-passing assembly within the handle, fixing the digital display module to the side of the water-passing assembly, and fixing the hydroelectric generator within the flow channel of the water-passing assembly, the digital display module, hydroelectric generator, and water-passing assembly form a modular structure. This modular structure allows for complete installation or disassembly within the handle. In particular, when making electrical connections between the digital display module and the hydroelectric generator, the limitations of the handle's internal space no longer apply, thus greatly improving the ease of assembly.

[0008] In addition, when the digital display module or the hydroelectric generator needs maintenance, simply remove the limit cap from the water outlet of the water-passing assembly, and the entire water-passing assembly can be pulled out from the rear end of the handle. This makes it easy to disconnect the digital display module from the hydroelectric generator for maintenance, thus providing high maintenance convenience.

[0009] In one of the above-mentioned shower heads, the front end of the limiting cap and the outer side wall are provided with several insertion ports along the circumferential direction.

[0010] The limiting cap is located inside the front end of the handle, where the space is too small to easily operate with tools. To address this, several slots are provided circumferentially between the front end of the limiting cap and the outer wall, allowing tools to be easily used to operate the limiting cap.

[0011] In the aforementioned shower head, the side of the water-passing component near the front end has a groove, the digital display module is positioned in the groove, the side of the water-passing component has a cable outlet hole, and the water-powered generator and the digital display module are connected by a connecting wire passing through the cable outlet hole.

[0012] The hydroelectric generator is fixed inside the water-passing assembly. After positioning the digital display module in the groove, a connecting wire is passed through the outlet hole to electrically connect the hydroelectric generator and the digital display module. With the above setup, the electrical connection or disconnection between the digital display module and the hydroelectric generator can be easily achieved.

[0013] In the aforementioned shower head, the water-passing assembly includes a rear water-passing body and a front water-passing body located in front of the rear water-passing body. The rear water-passing body and the front water-passing body are fixedly connected by a long strip-shaped connecting arm that runs along the handle. The flow channel includes a first flow channel located in the rear water-passing body and a second flow channel located in the front water-passing body. A switch is also provided inside the handle. The switch is located between the rear water-passing body and the front water-passing body. The switch is cylindrical with open ends. The two ends of the switch are respectively sleeved on the front end of the rear water-passing body and the rear end of the front water-passing body. A water-stopping structure is provided inside the switch. The switch can slide along the handle and control the first flow channel and the second flow channel to be separated inside the switch through the water-stopping structure. The side of the handle has a relief groove, and a push button that passes through the relief groove and is fixedly connected to the switch is provided outside the handle.

[0014] Based on the water flow assembly being configured to include a rear water flow body and a front water flow body located at the front end of the rear water flow body, with the rear water flow body and the front water flow body being fixedly connected by a long strip-shaped connecting arm along the handle, the switch is configured as a cylindrical shape with open ends. The two ends of the switch are respectively fitted onto the front end of the rear water flow body and the rear end of the front water flow body. The switch has a water-stopping structure inside, and the switch can slide along the handle and control the first flow channel and the second flow channel to be connected or disconnected within the switch through the water-stopping structure. This allows the switch to control whether the shower head is spraying water while also being directly integrated into the water flow assembly. In this way, the switch is installed directly within the handle while the water flow assembly is fixed inside the handle. Finally, the push button only needs to be passed through the clearance groove outside the handle and fixed to the switch, further improving the convenience of assembly.

[0015] During assembly, the two ends of the switch are first fitted onto the front end of the rear water passage body and the rear end of the front water passage body, respectively. Then, the connecting arm is used to fix the front water passage body and the rear water passage body together. In this way, the switch is integrated into the water passage assembly. The switch can slide back and forth but will not fall off the water passage assembly.

[0016] In the aforementioned shower head, the water-stopping structure includes a water guide pipe and a linkage ring. Several support rods are integrally fixed between the outer peripheral wall of the linkage ring and the inner peripheral wall of the switch component. An annular positioning groove is provided on the outer side of the middle part of the water guide pipe, and the linkage ring is locked in the annular positioning groove. The rear end of the water guide pipe is located in the first flow channel. Several water guide holes are provided circumferentially on the side of the rear end of the water guide pipe. A second sealing ring is provided in the front end of the rear water passage body. The second sealing ring is located in front of the water guide holes. The movement of the water guide pipe can expose the water guide holes outside the rear water passage body.

[0017] When the shower head is in the off state, the water guide hole is located inside the first flow channel and behind the second sealing ring. At this time, water flowing into the water guide pipe cannot flow into the inner hole of the switch. When water is needed, the user only needs to push the push button to move the switch. The switch, through the cooperation of the linkage ring and the annular positioning groove, will move the water guide pipe forward together. This causes the water guide hole to move out of the front end of the water body, so that the water flowing into the water guide pipe will flow into the inner hole of the switch, then into the second flow channel, and finally into the shower head and outwards.

[0018] In the above-mentioned shower head, a support sleeve is fixed inside the rear end of the front water passage body. The support sleeve is a cylindrical shape with an open rear end. The front end of the water guide pipe is inserted into the support sleeve, and a first sealing ring is provided on the outer side of the front end of the water guide pipe. There is a water passage gap between the outer wall of the support sleeve and the inner side wall of the rear end of the front water passage body.

[0019] By fixing a support sleeve inside the rear end of the front water passage, and inserting the front end of the water guide pipe into the support sleeve, support is provided for the front end of the water guide pipe, ensuring its stable movement. A first sealing ring is installed on the outer side of the front end of the water guide pipe to seal the gap between the water guide pipe and the support sleeve, preventing water flowing into the water guide pipe from leaking out through the gap. Furthermore, a gap for water passage is created between the outer wall of the support sleeve and the inner wall of the rear end of the front water passage, allowing the support sleeve to guide the movement of the water guide pipe while ensuring water can flow normally into the second flow channel.

[0020] In the above-mentioned shower head, the side of the support sleeve is provided with several ribs along the circumferential direction. The ribs are elongated along the axial direction of the handle. The rear end of the front water body is provided with an annular groove. Each rib is provided with a locking block on its side, and each locking block is locked in the annular groove.

[0021] The support sleeve is fixed to the front water passage body by the cooperation of the locking block and the annular locking groove. The protruding ribs allow water to pass through between the outer wall of the support sleeve and the inner wall of the rear end of the front water passage body.

[0022] In one of the above-mentioned shower heads, as another technical solution, the inner hole of the switch is stepped, with the front being larger than the back. The front end of the rear water passage has a columnar fitting part one, the outer diameter of which matches the inner diameter of the rear end of the switch. The rear end of the front water passage has a columnar fitting part two, the outer diameter of which matches the inner diameter of the front end of the switch. The first flow channel is opened into the fitting part one, and the inlet of the second flow channel is located at the rear end of the fitting part two. The water-stopping structure includes the inner wall of the rear end of the switch, a water outlet located on one side of the fitting part, and a water-stopping sealing ring sleeved and fixed on one side of the fitting part. The water-stopping sealing ring is located in front of the water outlet.

[0023] When the shower head is in the water-discharging state, the water outlet of the rear water passage is located in the inner hole of the front end of the switch. At this time, the water outlet is not closed, and the water in the pipe flows into the shower head and outwards through the first and second flow channels. During the water flow, the impeller in the hydroelectric generator rotates to generate electricity and supply power to the digital display module. At the same time, the temperature sensor integrated on the hydroelectric generator detects the water temperature and displays it on the digital display module, allowing the user to monitor the water temperature in real time. To turn off the shower head, the user simply pushes the push button to slide the switch. Because the positions of the front and rear water passages are fixed, as the switch slides forward, the water outlet is positioned in the inner hole of the rear end of the switch, thus blocking the water outlet and preventing water from flowing out of the first flow channel.

[0024] In the above-mentioned shower head, the rear end of the connecting arm is integrally fixed to the rear water flow body, the front end of the connecting arm has a slot, and the side of the front water flow body has a protruding plate-shaped part that is inserted into the slot.

[0025] During assembly, the switch assembly can be first placed over the rear water passage body, and then the front water passage body can be directly inserted into the switch assembly. Because the rear end of the connecting arm is integrally fixed to the rear water passage body, after the mating part of the front water passage body is inserted into the switch assembly, the plate-like part on the side of the front water passage body can be inserted into the slot at the front end of the connecting arm to directly and fix the connecting arm to the front water passage body.

[0026] In the above-mentioned shower head, the side of the switch component is provided with a connecting part, the push button is fixed to the connecting part, the side of the connecting arm is provided with a sliding groove, the side of the switch component is provided with a sliding strip, and the sliding strip is located in the sliding groove.

[0027] Because the connecting part needs to be fixed to the push button, there are positional requirements for it in the circumferential direction. This shower head has a sliding groove on the side of the connecting arm and a sliding strip on the side of the switch. The sliding strip is located in the sliding groove to ensure that the switch can slide back and forth without rotating in the circumferential direction. This ensures that the connecting part will not deviate after the switch is integrated into the water flow assembly.

[0028] Compared to existing technologies, this showerhead features a modular structure. By incorporating a water-passing assembly within the handle, fixing the digital display module to the side of the assembly, and securing the hydroelectric generator within the flow channel of the assembly, the digital display module, hydroelectric generator, and water-passing assembly form a single unit. This modular structure allows for complete installation and disassembly within the handle. Particularly significant is the ease of assembly, as the internal space of the handle no longer restricts electrical connections between the digital display module and the hydroelectric generator. Furthermore, when the digital display module or hydroelectric generator requires maintenance, simply removing the retaining cap from the outlet of the water-passing assembly allows the entire assembly to be pulled out from the rear of the handle. This facilitates easy disconnection of the digital display module from the hydroelectric generator for maintenance, further enhancing its ease of maintenance. Attached Figure Description

After the front end of the handle 1 is inserted into the docking hole 2a, rotating the handle 1 will allow the snap-fit ​​block to be inserted into the slot.

[0042] like Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, in this embodiment, the side of the water-passing component 5 near the front end has a groove 5b3, and the digital display module 3 is positioned within the groove 5b3. The side of the handle 1 near the front end has a window, and a transparent acrylic plate 7 is fixed inside the window. The side of the water-passing component 5 has a wire outlet hole 5a3, and the hydroelectric generator 4 and the digital display module 3 are connected by a connecting wire passing through the wire outlet hole 5a3. The hydroelectric generator 4 integrates a temperature sensor. The hydroelectric generator 4 is an existing structure, and how the hydroelectric generator 4 generates electricity and how it detects temperature are existing technologies, as detailed in a previously published patent application (patent number 201620298699.9) on a hydroelectric LED module. Furthermore, the water-passing assembly 5 includes a rear water-passing body 5a and a front water-passing body 5b located in front of the rear water-passing body 5a. The rear water-passing body 5a and the front water-passing body 5b are fixedly connected by a long strip-shaped connecting arm 5c along the handle 1. The flow channels include a first flow channel 5a2 located in the rear water-passing body 5a and a second flow channel 5b2 located in the front water-passing body 5b. The handle 1 also has a switch 8 located between the rear water-passing body 5a and the front water-passing body 5b. The switch 8 is a cylindrical shape with open ends, and its two ends are respectively sleeved on the front end of the rear water-passing body 5a and the rear end of the front water-passing body 5b. The switch 8 has a water-stopping structure. The switch 8 can slide along the handle 1 and the water-stopping structure controls the separation of the first flow channel 5a2 and the second flow channel 5b2 within the switch 8. The side of the handle 1 has a relief groove 1c, and the outside of the handle 1 has a push button 9 that passes through the relief groove 1c and is fixedly connected to the switch 8. The first flow channel 5a2 passes through the rear end of the rear water passage 5a. The water passage assembly 5 also includes a water inlet connector 5d threaded into the rear end of the rear water passage 5a. The hydroelectric generator 4 is positioned inside the rear water passage 5a by the water inlet connector 5d. The cable outlet 5a3 is located in the rear water passage 5a. The rear end of the water inlet connector 5d extends beyond the rear end of the handle 1. The water outlet 5b1 is located at the front end of the front water passage 5b, and the protruding edge 5a1 is located on the outer side of the rear end of the rear water passage 5a. Specifically, the water-stopping structure includes a water guide pipe 10 and a linkage ring 11. Several support rods 12 are integrally fixed between the outer peripheral wall of the linkage ring 11 and the inner peripheral wall of the switch component 8. An annular positioning groove 10b is provided on the outer side of the middle part of the water guide pipe 10. The linkage ring 11 is locked in the annular positioning groove 10b. In practice, several block-shaped locking teeth can be provided on the inner side of the linkage ring 11 along the circumferential direction. Each locking groove is locked in the annular positioning groove 10b. The rear end of the water guide pipe 10 is located in the first flow channel 5a2. Several water guide holes 10a are provided on the rear side of the water guide pipe 10 along the circumferential direction. The movement of the water guide pipe 10 can expose the water guide holes 10a outside the rear water body 5a.A support sleeve 13 is fixed inside the rear end of the front water passage 5b. The support sleeve 13 is a cylindrical shape with an open rear end. The front end of the water guide pipe 10 is inserted into the support sleeve 13, and a first sealing ring 14 is provided on the outer side of the front end of the water guide pipe 10. There is a water passage gap 16 between the outer wall of the support sleeve 13 and the inner side wall of the rear end of the front water passage 5b. A second sealing ring 15 is provided inside the front end of the rear water passage 5a. The second sealing ring 15 is located in front of the water guide hole 10a. Several ribs 13a are provided circumferentially on the side of the support sleeve 13. The ribs 13a are elongated along the axial direction of the handle 1. An annular groove 5b5 is provided inside the rear end of the front water passage 5b. Each rib 13a has a locking block 13b on its side, and each locking block 13b is locked in the annular groove 5b5.

[0043] Furthermore, such as Figure 5 and Figure 6 As shown, the rear end of the connecting arm 5c is integrally fixed to the rear water passage 5a. The front end of the connecting arm 5c has a slot 5c1. The side of the front water passage 5b has a protruding plate-shaped part 5b4, which is inserted into the slot 5c1. The side of the switch 8 has a protruding connecting part 8a. The push button 9 is fixed to the connecting part 8a. The side of the connecting arm 5c has a sliding groove 5c2. The side of the switch 8 has a sliding strip 8b, which is located in the sliding groove 5c2. The connecting part 8a is a square block along the handle. The side of the connecting part 8a facing the clearance groove 1c has a connecting groove 8a1. The push button 9 has a pin, which is inserted and fixed in the connecting groove 8a1. In this embodiment, there are two connecting arms 5c, which are arranged opposite each other. The switch 8 is located between the two connecting arms 5c. The notch 5c3 is provided on one of the connecting arms 5c.

[0044] When using, connect this shower head to the water pipe via the inlet connector 5d. With the shower head off, if... Figure 3 As shown, the water guide hole 10a of the water guide pipe 10 is located inside the rear water passage body 5a and behind the second sealing ring 15. At this time, the water flowing into the water guide pipe 10 cannot flow into the inner hole of the switch 8. When water is needed, the user only needs to push the push button 9 forward with the switch 8. The switch 8 will move forward with the water guide pipe 10 through the cooperation of the linkage ring 11 and the annular positioning groove 10b. This causes the water guide hole 10a to move out of the front end of the rear water passage body 5a. As a result, the water flowing into the water guide pipe 10 will flow into the inner hole of the switch 8, and then flow into the second flow channel 5b2 through the gap 16 between the outer wall of the support sleeve 13 and the inner wall of the rear end of the front water passage body 5b, and finally flow into the shower head 2 and outward. As the water flows, it drives the impeller inside the hydroelectric generator 4 to rotate and generate electricity, which then supplies power to the digital display module 3. At the same time, the temperature sensor integrated on the hydroelectric generator 4 detects the water temperature and displays it on the digital display module 3, allowing the user to monitor the water temperature in real time.

[0045] In actual assembly, the water guide pipe 10 can be positioned inside the switch piece 8 first, and then the switch piece 8 can be fitted over the front end of the rear water passage 5a. The rear end of the water guide pipe 10 will be inserted into the rear water passage 5a. Then, the front end of the front water passage 5b can be directly inserted into the switch piece 8 so that the front end of the water guide pipe 10 is inserted into the support sleeve 13. Because the rear end of the connecting arm 5c is integrally fixed to the rear water passage 5a, after the front water passage 5b is inserted into the switch piece 8, the plate-shaped part 5b4 on the side of the front water passage 5b can be inserted into the slot 5c 1 at the front end of the connecting arm 5c to fix the connecting arm 5c directly to the front water passage 5b. Then, the hydroelectric generator 4 is placed from the rear end of the rear water passage 5a and positioned by connecting the water inlet connector 5d inside the rear end of the rear water passage 5a. Then, the digital display module 3 is positioned in the groove 5b3 and connected to the digital display module 3 with connecting wires. In this way, the digital display module 3, the hydroelectric generator 4, and the switch 8 are all integrated into the water-passing assembly 5. Finally, simply insert the water-passing assembly 5 into the handle 1 from back to front. The outer protrusion 5a1 of the rear end of the water-passing assembly 5 will abut against the limiting step 1a inside the rear end of the handle 1. At the same time, the water outlet 5b1 at the front end of the water-passing assembly 5 will extend into the front end of the handle 1. Then, the limiting cap 6 is threaded to the outside of the water outlet 5b1 and abuts against the shoulder 1b inside the front end of the handle 1. In this way, the water-passing assembly 5 can be fixed in the handle 1 by the abutment of the protrusion 5a1 against the limiting step 1a and the abutment of the limiting cap 6 against the shoulder 1b.

[0046] By incorporating a water-passing assembly 5 within the handle 1, fixing the digital display module 3 to the side of the water-passing assembly 5, and fixing the hydroelectric generator 4 within the flow channel of the water-passing assembly 5, the digital display module 3, the hydroelectric generator 4, and the water-passing assembly 5 constitute a modular structure. This modular structure allows for complete installation or disassembly within the handle 1. Particularly when making electrical connections between the digital display module 3 and the hydroelectric generator 4, the internal space of the handle 1 is no longer a constraint, significantly improving assembly convenience. Furthermore, when the digital display module 3 or the hydroelectric generator 4 requires maintenance, simply removing the limiting cap 6 from the water outlet 5b1 of the water-passing assembly 5 allows the entire water-passing assembly 5 to be pulled out from the rear end of the handle 1. This facilitates easy disconnection of the digital display module 3 from the hydroelectric generator 4 for maintenance, thus providing high maintenance convenience as well.

[0047] Example 2

[0048] This embodiment is basically the same as the first embodiment in terms of structure and principle, except that: in this embodiment, the inner hole of the switch 8 is a stepped type with a larger front and a smaller rear. The front end of the rear water passage 5a has a columnar fitting part one, the outer diameter of which matches the inner diameter of the rear end of the switch 8. The rear end of the front water passage 5b has a columnar fitting part two, the outer diameter of which matches the inner diameter of the front end of the switch 8. The first flow channel 5a2 is opened into the fitting part one, and the inlet of the second flow channel 5b2 is located at the rear end of the fitting part two. The water-stopping structure includes the inner wall of the rear end of the switch 8, a water passage provided on one side of the fitting part, and a water-stopping sealing ring sleeved and fixed on one side of the fitting part. The water-stopping sealing ring is located in front of the water passage.

[0049] When the shower head is in the water-discharging state, the water outlet of the rear water outlet 5a is located in the front inner hole of the switch 8. At this time, the water outlet is not closed, and the water in the water pipe flows into the shower head 2 through the first flow channel 5a2 and the second flow channel 5b2 and then flows out. During the water flow, the impeller in the hydroelectric generator 4 is driven to rotate to generate electricity and supply power to the digital display module 3. At the same time, the temperature sensor integrated on the hydroelectric generator 4 detects the water temperature and displays it on the digital display module 3, allowing the user to monitor the water temperature in real time. When the shower head needs to be turned off, the user only needs to push the push button 9 to slide the switch 8. Because the positions of the front water outlet 5b and the rear water outlet 5a are fixed, as the switch 8 slides forward, the water outlet is located in the rear inner hole of the switch 8 and behind the water-stop sealing ring. This blocks the water outlet, preventing water from flowing out of the first flow channel 5a2.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
