Description

Technical Field

[0001] This utility model relates to the field of bathroom products technology, and in particular to a rotating massage water outlet mechanism and a shower head. Background Technology

[0002] In related technologies, showerheads are a common bathing product with a water spray function, but their water outlet angle and range are relatively fixed. Currently, to enrich the water spray patterns and provide users with a better water massage experience, massage showerheads have been introduced. Most current massage showerheads use a mechanism that drives the nozzles to rotate, changing the water spray pattern to achieve a rotary massage effect. However, because the nozzles rotate at high speeds and the water pattern frequency is fixed, they lack dynamic adjustment capabilities, resulting in poor massage effects and a monotonous user experience.

The planetary gears are connected to the water guide column. The impeller can receive the water flow flowing in through the inlet and is driven to rotate by the water flow, thereby causing the water guide column to rotate relative to the guide column, so that the water outlet is periodically aligned with the water baffle.

[0011] In one embodiment, the water-blocking member is placed inside the guide column along the first direction to divide the interior of the guide column into multiple independent flow channels, which are used to guide water flowing into the housing to the water-guiding column;

[0013] In one embodiment, the water-blocking component includes three water-blocking plates that intersect on the same axis and are placed inside the guide column to divide the interior of the guide column into three flow channels, and the included angle between two adjacent water-blocking plates is 120°.

[0014] Alternatively, the water-blocking component may include a single water-blocking plate disposed inside the guide column along a first direction, thereby dividing the interior of the guide column into two symmetrical flow channels.

[0015] In one embodiment, the outer casing includes a housing and a water inlet connector connected to the housing. The housing has a receiving cavity, and the fixing base is disposed within the receiving cavity. The water inlet connector has a water passage cavity for water passage, and a plurality of oblique water holes are spaced apart at the bottom of the water passage cavity. The oblique water holes are used to guide the water flowing into the water passage cavity into the receiving cavity to drive the impeller to rotate. The water inlet connector extends along the first direction and has a connecting portion communicating with the water passage cavity. The end of the connecting portion for connecting with an external water inlet pipe is the water inlet end.

[0016] In one embodiment, the end of the housing opposite to the water inlet connector extends along the first direction with an extension portion communicating with the receiving cavity. The extension portion has an opening, the water guide column is rotatably disposed in the extension portion, and the portion of the water guide column extending out of the extension portion is fitted with the planetary gear.

[0017] In one embodiment, the extension is provided in multiple parts, and each extension is rotatably provided with a water guide column, and a planetary gear is fitted on the portion of the corresponding water guide column that extends out of the extension.

[0018] In one embodiment, the fixed seat has a recessed cavity, the impeller is rotatably housed in the cavity, and the drive shaft of the impeller passes through the fixed seat and is connected to the sun gear.

When the fixed base is installed in the receiving cavity, the guide column extends into the water guide column, and a water baffle is provided on the side of the guide column facing the water outlet. As the water guide column rotates, the water outlet periodically aligns with the water baffle, thereby generating intermittent pulse water jets. This allows the user to experience intermittent water flow impact, resulting in a more comfortable massage effect and improving the user experience. Attached Figure Description

Therefore, features defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0039] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0040] like Figures 1 to 4 As shown in the figure, a rotary massage water outlet mechanism according to an embodiment of the present invention includes a housing 10, a water guide column 20, a fixed base 30, and a planetary reduction gear assembly 60. The housing 10 has a water inlet end 10a, allowing external water to enter the housing through the water inlet end 10a. The water guide column 20 is rotatably disposed inside the housing 10 and has multiple water outlet holes 20a for spraying out the water entering the housing 10 for use. A guide column 40 extends along a first direction X from the side of the fixed base 30 near the water guide column 20. The guide column 40 extends into the water guide column 20, and a water baffle 50 is provided on the side of the guide column 40 facing the water outlet holes 20a. When the water guide column 20 rotates relative to the guide column 40, the water outlet holes 20a periodically align with the water baffle 50.

[0041] In this embodiment, the rotating massage water outlet mechanism rotatably mounts the water guide column 20 within the housing 10 and connects a planetary gear 62 to the water guide column 20. The water flow flowing in through the inlet 10a drives the water guide column 20 to rotate within the housing. When the fixed base 30 is installed in the receiving cavity 11a, the guide column 40 extends into the water guide column 20, and a water baffle 50 is provided on the side of the guide column 40 facing the water outlet. As the water guide column 20 rotates, the water outlet 20a periodically aligns with the water baffle 50, thereby generating intermittent pulse water jets. This allows the user to experience intermittent water flow impacts, resulting in a more comfortable massage effect and enhancing the user experience.

[0042] It should be noted that when the water guide column 20 rotates to the position where the water outlet 20a is aligned with the water baffle 50, the water baffle 50 only blocks a portion of the water outlet 20a, and water can still flow out from the unblocked portion of the water outlet 20a. When the water guide column 20 rotates to the point where the water outlet 20a and the water baffle 50 are misaligned, the water outlet 20a is in a fully open state, and water flows out with a higher impact force. In other words, when the water guide column 20 is driven to rotate, the water outlet 20a on the water guide column 20 rotates relative to the water baffle 50 to alternately misalign or align with the water baffle 50, thereby producing an intermittent water jet effect.

[0043] For example, the driving force required to make the water guide column 20 rotate inside the housing is converted from the impact force of the incoming water flow. Therefore, in practical applications, the rotation of the water guide column 20 can be adjusted by adjusting the flow rate of the incoming water flow, thereby changing the pulse frequency of the water output to meet the needs of different users.

[0044] Please refer to Figure 3 and Figure 4 In one embodiment, the rotating massage water outlet mechanism further includes a planetary reduction assembly 60. The planetary reduction assembly 60 includes an impeller 61, multiple planetary gears 62, and a sun gear 63. The sun gear 63 is connected to the impeller 61 and meshes with the planetary gears 62. The planetary gears 62 are connected to the water guide column 20. The impeller 61 receives water flowing in through the inlet end 10a and is driven to rotate by the water flow, causing the water guide column 20 to rotate relative to the guide column 40, periodically aligning the water outlet with the water baffle. In other words, by cleverly installing the sun gear 63 on the impeller 61 and cooperating with the planetary gears 62 fitted on the water guide column 20, a planetary reduction assembly 60 is formed. This allows the high-speed rotational force of the water flow impact to be converted into a low-speed, high-torque driving force for the water guide column 20 when the impeller 61 rotates at high speed due to water flow impact. This ensures stable and powerful rotation of the water guide column 20 and greatly reduces the risk of jamming.

[0045] In one embodiment, the water-blocking member 50 is placed inside the guide column 40 along the first direction X to divide the interior of the guide column 40 into multiple independent flow channels 40a. The flow channels 40a are used to guide the water flowing into the housing 10 to the water guide column 20. That is, by placing the water-blocking member 50 inside the guide column 40 to divide the interior of the guide column 40 into multiple independent flow channels 40a, pressure crosstalk between different flow channels 40a can be effectively avoided, and the flow rate of each flow channel 40a can be balanced.

[0046] In one embodiment, multiple water outlets 20a are provided, all of which are distributed circumferentially at intervals. When the water guide column 20 rotates relative to the guide column 40, some of the water outlets 20a are aligned with the water baffle 50, while others are misaligned with the water baffle 50. That is, when the water guide column 20 is driven to rotate relative to the guide column 40, the water baffle 50 only blocks some of the water outlets 20a, and the water flow will still flow out from the unblocked water outlets 20a, avoiding abrupt changes in water flow in the traditional fully open or fully closed modes and reducing the water hammer effect.

[0047] In practical applications, please refer to Figure 5 and Figure 6 The number of water outlets 20a can be set to three, and all water outlets 20a are distributed at 120° intervals. Correspondingly, the water baffle 50 includes three water baffles 51, which intersect on the same axis and are placed inside the guide column 40 to divide the interior of the guide column 40 into three flow channels 40a, and the included angle between two adjacent water baffles 51 is 120°. That is, by setting three water outlets 20a in the guide column 20 and distributing the three water outlets 20a at 120° intervals, when the guide column 20 rotates to the position where the water outlets 20a are aligned with the water baffles 51, the water baffles 51 will block part of the water outlets 21, and the water flow can still flow out of the unblocked part of the water outlets 21. At this time, the water flow entering the guide column 40 flows out from the three flow channels 40a respectively, forming three water jets (see details for reference). Figure 7 This effectively avoids sudden changes in water flow that could lead to a poor user experience.

[0048] In another implementation, please refer to Figure 8 and Figure 9There are four water outlets 20a, all of which are spaced at 90° intervals along the circumference. Correspondingly, the water baffle 50 includes a single water baffle 51, which is disposed inside the guide column 40 along the first direction X to divide the interior of the guide column 40 into two symmetrical flow channels 40a. That is, by setting four water outlets 20a inside the guide column 20 and distributing them at 90° intervals, when the guide column rotates to the position where two of the water outlets 20a are aligned with the single water baffle 51, the water baffle 51 only blocks those two water outlets 20a, while the other two unblocked water outlets 20a maintain their original water flow. At this time, the water flowing into the guide column 40 flows out from the two flow channels 40a respectively, forming two streams of water (see details for reference). Figure 10 This allows for intermittent water jet effects. Furthermore, using a single baffle plate 51 instead of multiple combined baffle plates 51 reduces the number of parts and assembly steps, lowering processing complexity and cost.

[0049] In one embodiment, the outer casing 10 includes a housing 11 and a water inlet connector 12 connected to the housing 11. The housing 11 has a receiving cavity 11a, and the fixing base 30 is provided in the receiving cavity 11a. The water inlet connector 12 has a water passage cavity 12a for water passage, and a plurality of oblique water holes 12b are provided at intervals at the bottom of the water passage cavity 12a. The oblique water holes 12b are used to guide the water flow into the receiving cavity 11a to drive the impeller 61 to rotate. The water inlet connector 12 extends along the first direction X and has a docking part 12c connected to the water passage cavity 12a. The end of the docking part 12c that is connected to the external water inlet pipe is the water inlet end 10a.

[0050] For example, after connecting the docking part 12c to an external water inlet pipe, external water flow is introduced into the water passage chamber 12a. Since the bottom of the water passage chamber 12a is provided with multiple inclined water holes 12b, the water flow in the water passage chamber 12a impacts the impeller 61 at an inclined manner through the inclined water holes 12b, thereby driving the impeller 61 to rotate. The rotation of the impeller 61 drives the water guide column 20 to rotate, so that the water outlet 20a and the water baffle 50 alternately form misalignment or alignment to form intermittent pulse water output. In addition, the inclined water holes 12b are provided to convert the axial water flow into spiral flow or tangential flow in an inclined manner, so as to enhance the impact force of the water flow on the impeller 61 and improve the starting efficiency of the impeller 61.

[0051] In one embodiment, the housing 11 extends an extension 70 along a first direction X at one end away from the water inlet connector 12. The extension 70 connects to the receiving cavity 11a and has an opening 70a. A water guide column 20 is rotatably disposed within the extension 70, and a planetary gear 62 is fitted onto the portion of the water guide column 20 extending out of the extension 70. In other words, by extending an extension 70 from one end of the housing 11 away from the water inlet connector 12, and rotatably distributing a water guide column 20 within the extension 70, and then utilizing the engagement of a sun gear 63 driven by an impeller 61 with a planetary gear 62, the impeller 61 rotates under the impact of water flow, and the sun gear 63 drives the planetary gear 62 to rotate. This drives the water guide column 20 to rotate within the extension 70, causing the water outlet 20a and the water baffle 50 to alternately misalign or align, thereby generating intermittent pulsed water jets. This achieves full-coverage massage for the user, enhancing the user experience.

[0052] It should be noted that the extension 70 extending from the bottom surface of the outer casing 10 along the first direction X is intended to serve as a mounting base for the water guide column 20. The inner wall of the extension 70 cooperates with the water guide column 20 to provide radial support, ensuring stable rotation of the water guide column 20 and preventing axial movement of the water guide column 20.

[0053] Furthermore, if only one extension 70 is provided on the bottom surface of the housing 11, and no extensions are provided in other areas, the coverage area of ​​the water flow will be small, failing to achieve full-coverage massage for the user, resulting in a poor user experience. Therefore, in one embodiment, multiple extensions 70 are provided, all distributed at equal angular intervals around the center of the housing 10. Each extension 70 contains a rotatable water guide column 20, and a planetary gear 62 is fitted onto the portion of the corresponding water guide column 20 extending beyond the extension 70. A sun gear 63 meshes with multiple planetary gears 62. This effectively expands the water flow range, achieving full-coverage massage for the user and improving the user experience.

[0054] Please refer to Figure 11In one embodiment, the fixed base 30 has a recessed cavity 30a, in which the impeller 61 is rotatably housed. The drive shaft 61a of the impeller 61 passes through the fixed base 30 and is connected to the sun gear 63. The fixed base 30 has a drain outlet 30b that communicates with the cavity 30a, so that the water flowing into the cavity 30a can be directed to the water column 20. Thus, by forming the cavity 30a in the recess of the fixed base 30, the cavity 30a can serve as the working area of ​​the impeller 61 after it is subjected to the impact force of the water flow, preventing interference during the rotation of the impeller 61. At the same time, the cavity 30a can also increase the water pressure, so that the drain outlet 30b on the fixed base 30 can radiate evenly to the water column 20, avoiding local pressure concentration and scattering.

[0055] Please refer to Figure 11 In one embodiment, a guide portion 30c extends from the center of the bottom of the inner cavity 30a along the first direction X. The drive shaft 61a of the impeller 61 passes through the guide portion 30c and connects to the sun gear 63. That is, by extending the guide portion 30c from the center of the bottom of the inner cavity 30a along the first direction X, the drive shaft 61a of the impeller 61 can accurately pass through and connect to the sun gear 63. This simplifies the assembly process of the impeller 61, the sun gear 63, and the planetary gear 62, reduces manual adjustment costs, and at the same time, the guide portion can serve as an axial guiding structure for the drive shaft 61a, ensuring that the drive shaft 61a of the impeller 61 is aligned with the mounting axis of the sun gear 63, reducing eccentric force or radial runout, and improving power transmission efficiency.

[0056] Please refer to Figure 12 In one embodiment, the shell 11 includes a bottom wall 111 and a peripheral side wall 112. One end of the bottom wall 111 is connected to one end of the peripheral side wall 112 to form a receiving cavity 11a. An extension 70 is connected to the surface of the bottom wall 111 facing away from the peripheral side wall 112. It should be noted that the bottom wall 111 and the peripheral side wall 112 can be a single piece or separate pieces. That is, the bottom wall 111 and the peripheral side wall 112 can be manufactured using a one-piece molding process, or the bottom wall 111 and the peripheral side wall 112 can be formed as two separate components, i.e., the bottom wall 111 and the peripheral side wall 112 are molded separately and then connected to form the shell 11. Specifically, in this embodiment, the bottom wall 111 and the peripheral side wall 112 are manufactured using a one-piece molding process, i.e., the bottom wall 111 and the peripheral side wall 112 are a single piece. This eliminates the need for a connection between the bottom wall 111 and the peripheral side wall 112, ensuring the structural strength of the shell 11 and preventing cracking under the impact of high-speed water flow.

[0057] In one embodiment, the outer edge of the water inlet connector 12 has a plurality of connecting ears 12d distributed circumferentially, and the outer surface of the peripheral sidewall 112 has a plurality of mounting blocks 80 corresponding to the connecting ears 12d distributed circumferentially. The mounting blocks 80 are used to connect with the connecting ears 12d. In practical applications, the water inlet connector 12 is placed on the housing 11, and the connecting ears 12d of the water inlet connector 12 are aligned with the mounting blocks 80 on the peripheral sidewall 112. Then, fasteners (such as bolts) are passed through the connecting ears 12d and inserted into the mounting blocks 80, thereby realizing the detachable connection of the water inlet connector 12 to the housing 11, so that it can be quickly disassembled later, facilitating the replacement or maintenance of the impeller 61, planetary gear 62, sun gear 63, etc.

[0058] The working process of this utility model is as follows:

[0059] External water flows into the water passage chamber 12a from the inlet end 10a of the docking part 12c, and passes through the inclined water hole 12b opened at the bottom of the water passage chamber 12a, so that the water flows into the impeller 61 at an angle, thereby driving the impeller 61 to rotate. Since the impeller 61 is equipped with a sun gear 63, and the sun gear 63 meshes with the planetary gear 62 sleeved on the water guide column 20, the rotation of the impeller 61 can drive the planetary gear 62 to rotate, thereby driving the water guide column 20 to rotate inside the outer casing 10, so that the water outlet hole 20a on the water guide column 20 is periodically aligned with the water baffle 50, thereby generating intermittent pulse water jets.

[0060] This application also provides a shower head, including the rotating massage water outlet mechanism of the above embodiments.

[0061] The shower head according to the embodiments of this disclosure adopts the above-described rotating massage water outlet mechanism, and has the same technical effects as the above-described rotating massage water outlet mechanism, which will not be repeated here.

[0062] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
