Description

Technical Field

[0001] The present invention relates to the technical field of bathroom products, and in particular to an intermittent water outlet mechanism and a water outlet device. Background Art

[0002] Among the shower products with massage functions on the market, the frequency of intermittent water discharge is relatively fast, resulting in a poor massage pulse feeling and failing to achieve the expected visual effect and shower experience. For this reason, Chinese patent CN109647640A discloses a water outlet device with a low-speed water outlet flow. A planetary gear set is arranged in the water flow chamber to achieve the deceleration of the rotation of the rotating water diversion disk through multi-stage meshing rotation between gears, so that the water flow of the two water outlet chambers can be switched at a low speed to achieve the expected water splash shape and massage effect. However, in this scheme, more gears need to be arranged. In order to ensure the volume of the water outlet device, the size of each gear needs to be designed to be relatively small, which also means that the dimensional accuracy requirements of each gear are high. On the one hand, it is not conducive to production line assembly, and on the other hand, the cost of parts is also high. In addition, in this scheme, the rotating water diversion disk can only be provided with one water flow hole. Once the number of water flow holes is increased, it is difficult to achieve the effect of low-speed switching, so the shape of the water splash that can be formed is limited. Summary of the invention

[0003] The invention discloses an intermittent water outlet mechanism, aiming to improve the problems of the existing massage water outlet device, such as the complex structure and high cost which are not conducive to production.

[0005] As a further improvement, the water diversion plate is provided with two shifting parts along the diameter direction, the minimum distance between the shifting part and the axis of the shifting rod is smaller than the length of the shifting rod, and the maximum distance between the shifting part and the axis of the shifting rod is larger than the length of the shifting rod.

[0006] As a further improvement, the water diversion plate is provided with a rotating part on the side away from the driving part, the rotating part is inserted into the assembly hole at the bottom of the main body, the water hole runs through the water diversion plate, and the water outlet channel is installed or formed at the bottom of the main body.

[0007] As a further improvement, the reduction transmission assembly includes a driving gear coaxially arranged with the impeller and a driven gear meshing with the driving gear, and the shifting rod is coaxially arranged with the driven gear.

[0008] As a further improvement, the main body includes an upper shell and a lower shell, the two shells cooperate to form the water passage chamber, 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.

[0009] As a further improvement, a fixed frame is provided in the water passage chamber, the rotating shaft at one end of the driven gear is inserted in the upper shell body, and the rotating shaft at the other end is inserted in the fixed frame, and the top surface of the fixed frame is provided with an arc protrusion to limit the driven gear along the axial direction, the shift rod is arranged below the fixed frame, and is provided with a limiting portion for plugging with the driven gear, so that the shift rod rotates synchronously with the driven gear.

[0011] As a further improvement, the main body is provided with two water outlet channels, and the two water outlet channels are arranged to control the connection and disconnection with the water through hole through two symmetrically arranged water dividing plates.

[0012] As a further improvement, the main body is provided with four water outlet channels, and two adjacent water outlet channels are arranged to control the connection and disconnection with the water through hole through the same water dividing plate, and the water through hole is an arc hole.

[0013] A water outlet device is also provided, comprising a water outlet body and an intermittent water outlet mechanism as described above and arranged on the water outlet body.

[0014] By adopting the above technical solution, the present invention can achieve the following technical effects: 1. The present application sets the lever eccentrically relative to the water-dividing plate, so that the lever has at least a partial idle stroke during the rotation process.

Specific implementation manner

[0020] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention. Embodiment

[0021] Combined with Figures 1 to 14 , this embodiment provides an intermittent water outlet mechanism, including a body 1, the body 1 is provided with a water passage chamber 11, a water inlet channel 12 communicating with the water passage chamber 11, and at least one water outlet channel 13. Among them, an impeller 2, a speed reduction transmission assembly linked with the impeller 2, a poking rod 4, and a water distribution plate 5 are arranged in the water passage chamber 11. The poking rod 4 is eccentrically arranged relative to the water distribution plate 5 and is driven to rotate via the speed reduction transmission assembly. At least two poking parts 51 are arranged on the water distribution plate 5, so that the poking rod 4 has a partial idle rotation stroke during one rotation, and can switch the poking part 51 in contact with it, thereby prolonging the switching time between the alignment and conduction of the water passing holes 52 on the water distribution plate 5 and the water outlet channel 13 and the misalignment and sealing.

[0022] It should be noted that in this embodiment, the lever 4 is eccentrically arranged relative to the water-dividing plate 5, so that the lever 4 has at least a partial idling stroke during the rotation process, and the idling stroke is defined as the stroke of the lever 4 not contacting the toggle portion 51, that is, the water-dividing plate 5 will not rotate with the lever 4 during the idling process, thereby extending the water outlet time and sealing time of the water outlet channel 13, thereby reducing the water outlet frequency, ensuring that the water spray can form the expected visual effect, and improving the shower experience of massage water. Compared with the prior art, this embodiment has a simple structure and can achieve the effect of reducing the water outlet frequency without setting a planetary gear set for multi-stage deceleration, which is conducive to reducing costs, facilitating production and manufacturing, and thus improving market competitiveness.

[0023] In a preferred embodiment, the water-dividing disc 5 is provided with two toggle parts 51 along the diameter direction, the minimum distance between the toggle part 51 and the axis of the lever 4 is less than the length of the lever 4, and the maximum distance between the toggle 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 toggle part closer to its axis, so that the water-dividing disc 5 rotates. Since the lever 4 is eccentrically arranged relative to the water-dividing disc 5, the first toggle part abutted by it gradually rotates to be separated from the lever 4. At this time, the lever 4 enters the idling stroke, and the water-dividing disc 5 stops rotating and remains at the current position. When the lever 4 rotates to abut against the second toggle part, the water-dividing disc 5 rotates accordingly until the second toggle part rotates to be separated from the lever 4. The water-dividing disc 5 stops again and remains at the current position until the lever 4 abuts against the first toggle part. This cycle is repeated to reduce the water discharge frequency and ensure the water discharge effect.

[0024] Exemplarily, the water diverter plate 5 is provided with a rotating portion 53 on a side away from the toggle portion 51, the rotating portion 53 is inserted into the assembly hole at the bottom of the body 1, the water hole 52 is provided through the water diverter plate 5, and the water outlet channel 13 is installed or formed at the bottom of the body 1. Among them, the rotating portion 53 of the water diverter plate 5 is inserted into the assembly hole of the body 1, so that the rotation of the water diverter plate 5 is only driven by the toggle lever 4, reducing the matching size, thereby reducing the precision of the parts, which is beneficial to the assembly and manufacturing of the product.

[0025] On the basis of the above embodiment, in an optional embodiment of the present invention, 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, and 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, the two shells cooperate to form a water passage chamber 11, the water inlet channel 12 is arranged in the upper shell 14, and an inclined water groove 121 is arranged 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 arranged in the lower shell 15. The water flows into the water inlet channel 12, and then passes through the inclined water groove 121 so that the water flows obliquely to impact the impeller 2, thereby driving the impeller 2 to rotate, so as to synchronously drive the reduction transmission assembly, so that the lever 4 rotates. The water inlet channel 12 and the water outlet channel 13 are respectively arranged in the upper and lower shells to make the structure more compact and facilitate mold opening.

[0026] Preferably, a fixing frame 6 is provided in the water passage chamber 11, a rotating shaft at one end of the driven gear 32 is inserted in the upper housing 14, and a rotating shaft at the other end is inserted in the fixing frame 6, a circular arc protrusion 61 is provided on the top surface of the fixing frame 6 to limit the driven gear 32 in the axial direction, and the shifting rod 4 is arranged below the fixing frame 6 and provided with a limiting portion 41 for plugging with the driven gear 32, so that the shifting rod 4 rotates synchronously with the driven gear 32. Among them, the provision of the circular arc protrusion 61 can reduce the contact area between the driven gear 32 and the fixing frame 6, thereby reducing the rotation resistance, and ensuring that the rotation of the driven gear 32 can proceed smoothly.

[0027] In another embodiment, the lower shell 15 is provided with a sealing groove at a position corresponding to the water diversion tray 5, and a sealing ring 151 is embedded in the sealing groove for sealing against the water diversion tray 5, and the sealing ring 151 is configured to at least partially protrude from the inner bottom surface of the lower shell 15. The sealing ring 151 and the lower shell 15 are molded by secondary encapsulation to prevent the sealing ring 151 from being lifted or separated from the sealing groove when the water diversion tray 5 rotates, thereby ensuring the sealing effect. At the same time, the provision of the sealing ring 151 can reduce the contact area between the water diversion tray 5 and the inner bottom surface of the body 1, thereby correspondingly reducing the rotation resistance of the water diversion tray 5 and ensuring stable water discharge.

[0028] On the basis of the above embodiment, in an optional embodiment of the present invention, the body 1 is provided with two water outlet channels 13, and the two water outlet channels 13 are arranged to control the opening and closing of the water hole 52 through two symmetrically arranged water diversion plates 5. The two water diversion plates are driven by two driven gears 32 respectively. Specifically, the two driven gears 32 are symmetrically distributed on both sides of the driving gear 31, so that the driving gear 31 is subjected to balanced force, further ensuring stable water outlet. Figure 4 and Figure 5 When the driving gear 31 rotates, the two driven gears 32 rotate in opposite directions, and the corresponding rotation positions of the levers 4 are also different, so that the two water outlet channels 13 discharge water alternately.

[0029] In other embodiments, referring to Figures 11 to 14 , the main body 1 is provided with four water outlet channels 13. Two adjacent water outlet channels 13 are arranged to control the on-off of the water passing holes 52 through the same water distribution plate 5. Among them, the water passing holes 52 are arc-shaped holes to extend the conduction time between the water outlet channels 13 and the water passing holes 52, and further reduce the switching frequency between two adjacent water outlet channels 13. Specifically, the four water outlet channels 13 are respectively a first water outlet channel, a second water outlet channel, a third water outlet channel and a fourth water outlet channel. The first water outlet channel and the second water outlet channel control the on-off of the first water passing hole through the first water distribution plate. The third water outlet channel and the fourth water outlet channel control the on-off of the second water passing hole through the second water distribution plate. The two water distribution plates 5 are symmetrically arranged and drive the lever 4 through the symmetrically arranged driven gears 32, so as to form the water outlet effect of the four water outlet channels 13 discharging water alternately. Compared with the prior art, there is no need to double the number of reduction gears, the structure is simpler, and more kinds of water spray can be formed to meet the needs of different users.

[0030] The present invention further provides a water outlet device, which includes a water outlet main body and an intermittent water outlet mechanism as described in any one of the above embodiments disposed on the water outlet main body. Among them, the water outlet main body can be a shower head, a ceiling spray, a spray gun, a shoulder spray, a waist spray, etc., without specific limitation. By arranging the intermittent water outlet mechanism on the water outlet main body, the water outlet main body has intermittent or alternating water outlet, so as to form a massage effect, and its water outlet frequency is low, which can effectively improve the shower experience.
