Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of bathroom products, and particularly relates to an intermittent water outlet mechanism and a water outlet device. BACKGROUND

[0002] Among the shower products with massage function on the market, the frequency of intermittent water outlet is relatively fast, which causes poor massage pulse feeling and cannot achieve the expected visual effect and shower experience. Therefore, the water outlet device with low-speed water flow disclosed in Chinese patent CN109647640A sets up a planetary gear set in the water passing cavity to realize the deceleration of the rotating water distribution disc through the multi-stage meshing rotation between the gears, so that the water flow of the two water outlet cavities can be switched at low speed to achieve the expected water spray shape and massage effect. However, in this scheme, a large number of gears need to be set up, and in order to ensure the size of the water outlet device, the size of each gear needs to be designed to be relatively small, which also means that the size precision of each gear is high, which is not conducive to line assembly on the one hand and the cost of parts is also high on the other hand. In addition, in this scheme, the rotating water distribution disc can only be provided with one water passing hole, and once the number of water passing holes is increased, it is difficult to achieve the effect of low-speed switching, so the water spray shape that can be formed is limited. SUMMARY

[0003] The utility model discloses an intermittent water outlet mechanism, which aims at improving the problems of complex structure and high cost of existing massage water outlet devices, which are not conducive to production.

[0004] The utility model discloses the following scheme:

[0005] An intermittent water outlet mechanism, comprising a body, the body is equipped with a water passing cavity and a water inlet channel and at least one water outlet channel that are communicated with the water passing cavity, wherein the water passing cavity is configured with an impeller, a speed reduction transmission assembly that is set in linkage with the impeller, a lever and a water distribution disc, the lever is set eccentrically relative to the water distribution disc and is driven to rotate through the speed reduction transmission assembly, at least two levering parts are provided on the water distribution disc, so that the lever has a part idle stroke in the process of rotating one circle and can switch the levering part abutting therewith, thereby prolonging the switching time between the water passing hole on the water distribution disc and the water outlet channel in alignment conduction and misalignment sealing.

[0006] As a further improvement, the water distribution disc is provided with two levering parts in the diameter direction, the minimum distance between the levering part and the lever shaft center is less than the length of the lever, and the maximum distance between the levering part and the lever shaft center is greater than the length of the lever.

[0007] As a further improvement, the water diversion disc is provided with a rotating part on the side away from the toggle part, the rotating part is inserted into the assembly hole of the bottom of the body, the water passing hole is provided through the water diversion disc, and the water outlet channel is arranged or formed in the bottom of the body.

[0008] As a further improvement, the speed reduction transmission assembly comprises a driving gear coaxially arranged with the impeller and a driven gear engaged with the driving gear, and the toggle lever is coaxially arranged with the driven gear.

[0009] As a further improvement, the body comprises an upper shell and a lower shell, the two shells are matched to form the water passing cavity, the water inlet channel is arranged in the upper shell, and an inclined water groove is arranged in the water inlet channel, the impeller is arranged at the water outlet end of the inclined water groove, and the water outlet channel is arranged in the lower shell.

[0010] As a further improvement, a fixing frame is arranged in the water passing cavity, the rotating shaft of one end of the driven gear is inserted into the upper shell, and the rotating shaft of the other end is inserted into the fixing frame, the top surface of the fixing frame is provided with a circular arc protrusion to limit the driven gear in the axial direction, the toggle lever is arranged below the fixing frame and is provided with a limiting part for being inserted into the driven gear, so that the toggle lever rotates synchronously with the driven gear.

[0011] As a further improvement, the lower shell is recessed with a sealing groove corresponding to the position of the water diversion disc, a sealing ring for abutting and sealing with the water diversion disc is embedded in the sealing groove, and the sealing ring is arranged to at least partially protrude from the inner bottom surface of the lower shell.

[0012] As a further improvement, the body is provided with two water outlet channels, and the two water outlet channels are arranged to control the on-off of the water passing hole through two symmetrically arranged water diversion discs.

[0013] As a further improvement, the body is provided with four water outlet channels, and adjacent two water outlet channels are arranged to control the on-off of the water passing hole through the same water diversion disc, and the water passing hole is an arc-shaped hole.

[0014] Another water outlet device is provided, which comprises a water outlet body and the intermittent water outlet mechanism as claimed in any one of the above.

[0015] By adopting the above technical scheme, the following technical effects can be achieved:

[0016] 1. This application eccentrically positions the lever relative to the water distribution plate, ensuring that the lever has at least a partial free-spinning stroke during rotation. This free-spinning stroke is defined as the stroke during which the lever does not contact the actuating part. In other words, the water distribution plate does not rotate during the free-spinning process, thereby extending the water flow and sealing time of the water outlet channel, thus reducing the water flow frequency.

[0018] 3. Setting the water passage hole as an arc-shaped hole can extend the conduction time between the water outlet channel and the water passage hole, further reducing the switching frequency of the two water outlet channels. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0041] Combination Figures 1 to 14 This embodiment provides an intermittent water outlet mechanism, including a body 1. The body 1 has a water passage chamber 11 and an inlet channel 12 and at least one outlet channel 13 communicating with the water passage chamber 11. The water passage chamber 11 is equipped with an impeller 2, a speed reduction transmission assembly linked to the impeller 2, a lever 4, and a water distribution plate 5. The lever 4 is eccentrically positioned relative to the water distribution plate 5 and is driven to rotate via the speed reduction transmission assembly. The water distribution plate 5 is provided with at least two actuating parts 51 so that the lever 4 has a partial free-spinning stroke during one rotation and can switch the actuating part 51 that abuts against it, thereby extending the switching time between the alignment and misalignment sealing of the water passage hole 52 on the water distribution plate 5 and the water outlet channel 13.

[0042] It should be noted that in this embodiment, the lever 4 is eccentrically positioned relative to the water distribution plate 5 so that the lever 4 has at least a partial free-spinning stroke during rotation. The free-spinning stroke is defined as the stroke during which the lever 4 does not contact the actuating part 51. In other words, the water distribution plate 5 does not rotate during the free-spinning stroke of the lever 4, thereby extending the water outlet time and sealing time of the water outlet channel 13, thus reducing the water outlet frequency. This ensures that the water spray can form the expected visual effect, enhancing the shower experience of the massage water. Compared with existing technologies, this embodiment has a simple structure and achieves the effect of reducing the water outlet frequency without the need for a planetary gear set for multi-stage speed reduction. This helps reduce costs, facilitates manufacturing, and thus enhances market competitiveness.

[0043] In a preferred embodiment, the water distribution plate 5 is provided with two actuating parts 51 along its diameter. The minimum distance between the actuating part 51 and the axis of the lever 4 is less than the length of the lever 4, and the maximum distance between the actuating part 51 and the axis of the lever 4 is greater than the length of the lever 4. When the lever 4 rotates, it abuts against the first actuating part closer to its axis, causing the water distribution plate 5 to rotate. Since the lever 4 is eccentrically positioned relative to the water distribution plate 5, the first actuating part gradually rotates until it disengages from the lever 4. At this time, the lever 4 enters its free-spinning stroke, and the water distribution plate 5 stops rotating and remains in its current position. When the lever 4 rotates to abut against the second actuating part, the water distribution plate 5 rotates accordingly until the second actuating part rotates to disengage from the lever 4. The water distribution plate 5 then stops again and remains in its current position until the lever 4 abuts against the first actuating part. This cycle repeats to reduce the water output frequency and ensure the water output effect.

[0044] For example, the water distribution plate 5 has a rotating part 53 on the side away from the actuating part 51. The rotating part 53 is inserted into the mounting hole at the bottom of the body 1. The water passage hole 52 passes through the water distribution plate 5, and the water outlet channel 13 is installed or formed at the bottom of the body 1. The rotating part 53 of the water distribution plate 5 is inserted into the mounting hole of the body 1, so that the rotation of the water distribution plate 5 is only caused by the action of the lever 4, reducing the mating dimensions, thereby reducing the precision of the parts and facilitating the assembly and manufacturing of the product.

[0045] Based on the above embodiments, in an optional embodiment of this utility model, the reduction transmission assembly includes a driving gear 31 coaxially arranged with the impeller 2 and a driven gear 32 meshing with the driving gear 31. The lever 4 is coaxially arranged with the driven gear 32. Further, the body 1 includes an upper shell 14 and a lower shell 15, which cooperate to form a water passage cavity 11. A water inlet channel 12 is provided in the upper shell 14, and an inclined water groove 121 is provided in the water inlet channel 12. The impeller 2 is arranged at the water outlet end of the inclined water groove 121, and the water outlet channel 13 is provided in the lower shell 15. Water flows in from the water inlet channel 12, and then through the inclined water groove 121, the water flow obliquely impacts the impeller 2, thereby driving the impeller 2 to rotate, so as to synchronously drive the reduction transmission assembly, causing the lever 4 to rotate. The water inlet channel 12 and the water outlet channel 13 are respectively provided in the upper and lower shells to make the structure more compact and facilitate mold opening.

[0046] Preferably, a fixed frame 6 is provided inside the water passage cavity 11. One end of the driven gear 32 is inserted into the upper housing 14, and the other end is inserted into the fixed frame 6. The top surface of the fixed frame 6 is provided with an arc-shaped protrusion 61 to limit the driven gear 32 axially. The lever 4 is arranged below the fixed frame 6 and is provided with a limiting part 41 for engaging with the driven gear 32, so that the lever 4 rotates synchronously with the driven gear 32. The arc-shaped protrusion 61 reduces the contact area between the driven gear 32 and the fixed frame 6, thereby reducing rotational resistance and ensuring that the driven gear 32 can rotate smoothly.

[0047] In another embodiment, the lower housing 15 has a recessed sealing groove corresponding to the water distribution plate 5. A sealing ring 151 is embedded in the sealing groove to abut and seal against the water distribution plate 5. The sealing ring 151 is configured to at least partially protrude from the inner bottom surface of the lower housing 15. The sealing ring 151 and the lower housing 15 are formed by secondary overmolding to prevent the sealing ring 151 from being lifted or detached from the sealing groove when the water distribution plate 5 rotates, thus ensuring a good seal. Simultaneously, the sealing ring 151 reduces the contact area between the water distribution plate 5 and the inner bottom surface of the main body 1, thereby reducing the rotational resistance of the water distribution plate 5 and ensuring stable water output.

[0048] Based on the above embodiments, in an optional embodiment of this utility model, the main body 1 is provided with two water outlet channels 13. The two water outlet channels 13 are configured to control the opening and closing of the water passage holes 52 via two symmetrically arranged water distribution plates 5. The two water passage plates are driven by two driven gears 32, specifically, the two driven gears 32 are symmetrically distributed on both sides of the driving gear 31 to ensure that the driving gear 31 is subjected to balanced force, further ensuring stable water output. (Refer to...) Figure 4 and Figure 5 When the driving gear 31 rotates, the two driven gears 32 rotate in opposite directions, and the corresponding levers 4 rotate in different positions, causing the two water outlet channels 13 to alternately discharge water.

[0049] In other embodiments, refer to Figures 11 to 14 The main body 1 has four water outlet channels 13. Adjacent water outlet channels 13 are connected to a common water distribution plate 5 via a shared water passage 52. The water passage 52 is an arc-shaped hole to extend the connection time between the water outlet channel 13 and the water passage 52, further reducing the switching frequency between adjacent water outlet channels 13. Specifically, the four water outlet channels 13 are designated as a first, second, third, and fourth water outlet channel. The first and second water outlet channels are connected to a first water passage via a first water distribution plate, while the third and fourth water outlet channels are connected to a second water passage via a second water distribution plate. The two water distribution plates 5 are symmetrically arranged and, via symmetrically configured driven gears 32, drive a lever 4, thus creating an alternating water flow effect from the four water outlet channels 13. Compared to existing technologies, this design eliminates the need for a significantly larger number of reduction gears, resulting in a simpler structure and the ability to generate a wider variety of water spray patterns to meet the needs of different users.

[0050] This utility model also provides a water outlet device, including a water outlet body and an intermittent water outlet mechanism as described in any of the above embodiments, disposed on the water outlet body. The water outlet body can be a shower head, overhead spray, spray gun, shoulder spray, waist spray, etc., and is not specifically limited. By setting an intermittent water outlet mechanism on the water outlet body, the water outlet body can have intermittent or alternating water output, thereby creating a massage effect. Its low water output frequency effectively enhances the showering experience.

[0051] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
