Description

Technical Field

[0001] The present invention relates to the technical field of sanitary ware, and in particular to a water distribution device and a shower head. Background Art

[0002] A shower head is a common sanitary ware. The functions of traditional shower heads are relatively single, usually with only a single type of water spray. With the improvement of people's living standards, the single water spray of traditional shower heads can no longer meet people's requirements for shower experience. In order to improve the functions of the shower head and increase the water spray styles, existing shower heads often use a dual-inlet channel and dual-outlet channel method to expand the water spray styles. During the process of water spray switching, a water distribution device is required to switch the water spray styles. The water distribution device can connect different inlet channels to different outlet channels. In this way, after switching the inlet channel, water can be sprayed out from different outlet channels, and the nozzle styles of different outlet channels are different, enabling the switching of different water sprays. However, such a mechanism usually requires multiple layers of outlet channels to be connected to different nozzles respectively. Such a design will thicken the overall structure of the shower head, and it is also necessary to design different nozzle structures separately, which increases the material cost and production cost while also increasing the probability of damage and repair. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a water distribution device that can streamline the water distribution structure, spray different water sprays with only one layer of outlet channel, effectively reduce the thickness of the shower head, and has a simple structure and reliable use.

[0004] To solve the above technical problem, the present invention provides a water distribution device, including an inlet cover, an inclined hole plate, and an outlet cover. The inlet cover includes an inner inlet hole and an outer inlet hole, and water can enter the inclined hole plate from the inner inlet hole or the outer inlet hole. The inclined hole plate is disposed between the inlet cover and the outlet cover. The outlet cover includes an outlet cylinder, and the outlet cylinder is located at the bottom of the outlet cover and is used for spraying water.

[0005] The water distribution device further includes a switching mechanism and a swinging mechanism. The switching mechanism includes a first water distribution inclined hole and a second water distribution inclined hole disposed on the inclined hole plate. The swinging mechanism includes a column and a swinging rotating plate sleeved on the column. The first water distribution inclined hole and the second water distribution inclined hole can make the swinging rotating plate swing around the column in opposite directions respectively. The swinging rotating plate is located at the water inlet end of the outlet cylinder, and the swinging direction of the swinging rotating plate can respectively control the water to enter the outlet cylinder tangentially or axially.

[0006] As an improvement of the above solution, the water outlet cylinder includes a retaining boss, a water inlet cavity, and a water outlet nozzle. The retaining boss is located inside the water outlet cover and protrudes from the bottom of the water outlet cover. An inlet groove for water inlet is formed on the side of the retaining boss. The water inlet cavity is communicated with the water outlet nozzle. The water outlet nozzle is located at the bottom of the water outlet cylinder and on the central axis of the water inlet cavity. Water can enter the water inlet cavity from the inlet groove and be sprayed out from the water outlet nozzle.

[0007] As an improvement of the above solution, the side plates on both sides of the groove body of the inlet groove are a first side plate and a second side plate respectively. The distance from the first side plate to the axis of the water inlet cavity is less than the distance from the second side plate to the axis of the water inlet cavity. The second side plate is smoothly connected to the side wall of the water inlet cavity.

[0008] As an improvement of the above solution, the swinging turning plate includes a connecting ring and a plurality of guiding strips. The plurality of guiding strips protrude radially from the outer side and the inner side of the connecting ring and are evenly distributed.

[0009] The number of the water outlet cylinders is multiple. The positions of the multiple inlet grooves respectively correspond to the positions of the multiple guiding strips. The guiding strips can be inserted into the inlet grooves. The swinging turning plate can swing counterclockwise or clockwise. The guiding strips can move closer to the first side plate or closer to the second side plate following the swinging turning plate.

[0010] As an improvement of the above solution, the width of the inlet groove is greater than the width of the guiding strip. When the guiding strip is in contact with the first side plate, a first flow channel can be formed between the guiding strip and the second side plate. Water can enter the water inlet cavity from the first flow channel, and the water inlet direction is the tangential direction of the water inlet cavity.

[0011] When the guiding strip is in contact with the second side plate, a second flow channel can be formed between the guiding strip and the first side plate. Water can enter the water inlet cavity from the second flow channel, and the water inlet direction is the central direction of the water inlet cavity.

[0012] As an improvement of the above solution, the inclination directions of both the first water diversion inclined hole and the second water diversion inclined hole are towards the space between the first water diversion inclined hole and the second water diversion inclined hole. The water entering the first water diversion inclined hole on the inclined hole plate has an opposite direction to the water entering the second water diversion inclined hole.

[0013] Both the first water diversion inclined hole and the second water diversion inclined hole are inclined towards the circumferential direction of the water outlet cover.

[0014] As an improvement to the above solution, the swing rotating plate further includes a plurality of swing bars. The plurality of swing bars protrude radially from the outer and inner sides of the connecting ring and are evenly distributed. The swing bars are arranged between the water outlet of the first water diversion inclined hole and the water outlet of the second water diversion inclined hole. Water can come out from the first water diversion inclined hole or the second water diversion inclined hole to push the swing bars to swing, and the swing bars can drive the swing rotating plate to swing counterclockwise or clockwise.

[0015] As an improvement to the above solution, the water diversion device further includes a water diversion cover. The water diversion cover is provided with a first inlet hole and a second inlet hole. The first inlet hole is communicated with the inner water inlet hole, and the second inlet hole is communicated with the outer water inlet hole.

[0016] As an improvement to the above solution, the water diversion cover is further provided with a first water diversion chamber, a second water diversion chamber and a water diversion partition. The first water diversion chamber is communicated with the first inlet hole, the second water diversion chamber is communicated with the second inlet hole. The first water diversion chamber and the second water diversion chamber are isolated from each other by the water diversion partition. The first water diversion chamber is communicated with the first water diversion inclined hole, and the second water diversion chamber is communicated with the second water diversion inclined hole.

[0017] The present invention also provides a shower head, including the water diversion device as described above.

[0018] Implementing the present invention has the following beneficial effects:

[0019] The water diversion device of the present invention is provided with a switching mechanism and a swinging mechanism. The water coming in from the water inlet cover can respectively enter the first water diversion inclined hole and the second water diversion inclined hole in the switching mechanism. When the water enters the first water diversion inclined hole, the impact force of the water can drive the swinging rotating plate in the swinging mechanism to swing around the upright column. During the swinging process, the water will enter the water outlet cylinder tangentially, and the water will enter the water outlet cylinder under the action of centrifugal force and spray out from the water outlet cylinder. At this time, the sprayed water is granular water; when the water enters the second water diversion inclined hole, the impact force of the water can drive the swinging rotating plate in the swinging mechanism to swing around the upright column in the other direction. During the swinging process, the water will directly enter the water outlet cylinder axially and then directly spray out from the water outlet cylinder. At this time, the sprayed water is flower sprinkler water. Therefore, the present invention controls the water to enter the water outlet cylinder from different directions through the switching mechanism and the swinging mechanism, and can achieve the spraying effect of different water flowers without relying on multiple water outlet channels, having the advantages of simple structure and relatively thin thickness, saving material costs and production costs while effectively reducing the thickness of the shower head, being reliable in use, and also reducing the probability of damage and repair.

[0030] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inner, and outer that appear or will appear in the text of the present invention are only based on the drawings of the present invention and do not specifically limit the present invention.

[0031] See Figure 1 and Figure 2, an embodiment of the present invention discloses a water separation device 10, which includes an inlet cover 1, an inclined hole plate 6, and an outlet cover 2. The inlet cover 1 includes an inner water inlet hole 11 and an outer water inlet hole 12. Water can enter the inclined hole plate 6 from the inner water inlet hole 11 or the outer water inlet hole 12. Before switching the water spray, water only enters the inclined hole plate 6 from a single channel. For example, it first enters the inclined hole plate 6 from the inner water inlet hole 11. When it is necessary to switch the water spray, the water inlet channel will be changed from the inner water inlet hole 11 to the outer water inlet hole 12. An existing water separation switching mechanism can be installed in front of the inner water inlet hole 11 and the outer water inlet hole 12, which can make the water path switch between the inner water inlet hole 11 and the outer water inlet hole 12. In this embodiment, the inner water inlet hole 11 is located at the center of the inlet cover 1, and the outer water inlet hole 12 is located at a position closer to the outside in the inlet cover 1. The inclined hole plate 6 is arranged between the inlet cover 1 and the outlet cover 2. The inclined hole plate 6 is provided with inclined holes. The water that enters the inlet cover 1 can pass through the inclined hole plate 6. The outlet cover 2 includes an outlet cylinder 21. The outlet cylinder 21 is located at the bottom of the outlet cover 2, and the outlet cylinder 21 is used for spraying water spray. In order to separate the incoming water and be able to separate two kinds of water sprays in the same outlet cylinder 21, the water separation device 10 further includes a switching mechanism 4 and a swinging mechanism 5. The switching mechanism 4 includes a first water separation inclined hole 41 and a second water separation inclined hole 42 provided on the inclined hole plate 6. Water can enter the outlet cylinder 21 separately through the first water separation inclined hole 41, or enter the outlet cylinder 21 separately through the second water separation inclined hole 42. The swinging mechanism 5 includes a column 51 and a swinging rotating plate 52 sleeved on the column 51. The first water separation inclined hole 41 and the second water separation inclined hole 42 can make the swinging rotating plate 52 swing around the column 51 in two directions respectively.

[0032] Specifically, when water enters from the first water diversion inclined hole 41, under the action of the water impact force, the water can drive the swing turntable 52 to rotate in one direction. Since the swing turntable 52 is located at the water inlet end of the water outlet cylinder 21, after the swing turntable 52 swings, the water will enter the water inlet end of the water outlet cylinder 21 at an angle. The swing direction of the swing turntable 52 can respectively control the water to enter the water outlet cylinder 21 tangentially or axially. In this embodiment, when water enters from the first water diversion inclined hole 41, the swing turntable 52 will swing counterclockwise. Since the water blocking position of the swing turntable 52 changes, the water will enter the water outlet cylinder 21 from the tangential direction of the water outlet cylinder 21. At this time, the water will rotate along the inner wall of the water outlet cylinder 21 in the water outlet cylinder 21, and the water flower pattern coming out of the water outlet cylinder 21 is granular water. When water enters from the second water diversion inclined hole 42, the swing turntable 52 will swing clockwise. At this time, the water blocking position of the swing turntable 52 changes again, and the water will directly enter the water outlet cylinder 21 from the central axis direction of the water outlet cylinder 21 and be directly ejected from the water outlet cylinder 21. At this time, the water will not rotate along the inner wall of the water outlet cylinder 21. Therefore, the water flower pattern coming out of the water outlet cylinder 21 is ordinary sprinkler water. The embodiment of the present invention does not adopt the method of an ordinary multi-layer water outlet channel to switch the water flower pattern, but utilizes the rotation characteristic and adopts the method of changing the water inlet angle to realize the switching of two water flower patterns in the same layer of water inlet channel, which has the advantages of simple structure and thin thickness.

[0033] The beneficial effects of the embodiment of the present invention are as follows:

[0034] In the water distribution device 10 according to the embodiment of the present invention, a switching mechanism 4 and a swinging mechanism 5 are provided. The water entering from the water inlet cover 1 can enter the first water distribution inclined hole 41 and the second water distribution inclined hole 42 in the switching mechanism 4 respectively. When the water enters the first water distribution inclined hole 41, the impact force of the water can drive the swinging plate 52 in the swinging mechanism 5 to swing around the column 51. During the swinging process, the water will enter the water outlet cylinder 21 tangentially, and the water will enter the water outlet cylinder 21 under the action of centrifugal force and spray out from the water outlet cylinder 21. At this time, the sprayed water is granular water; when the water enters the second water distribution inclined hole 42, the impact force of the water can drive the swinging plate 52 in the swinging mechanism 5 to swing around the column 51 in the other direction. During the swinging process, the water will directly enter the water outlet cylinder 21 axially and then directly spray out from the water outlet cylinder 21. At this time, the sprayed water is sprinkler water. Therefore, the present invention controls the water to enter the water outlet cylinder 21 from different directions through the switching mechanism 4 and the swinging mechanism 5, and can achieve the spraying effect of different water flowers without relying on multiple water outlet channels. It has the advantages of simple structure and thin thickness, effectively reducing the thickness of the shower head while saving material costs and production costs, being reliable in use, and also reducing the probability of damage and maintenance.

[0035] See Figure 3 and Figure 4 In order to enable the same water outlet cylinder 21 to spray two kinds of water flowers respectively, the water outlet cylinder 21 includes a gear position convex platform 211, a water inlet cavity 212 and a water outlet nozzle 213. The gear position convex platform 211 is located in the water outlet cover 2 and protrudes from the bottom of the water outlet cover 2. A water inlet groove 22 for water inlet is provided on the side of the gear position convex platform 211. The water enters the water outlet cylinder 21 from the water inlet groove 22. The water inlet cavity 212 is communicated with the water outlet nozzle 213. The water outlet nozzle 213 is located at the bottom of the water outlet cylinder 21 and on the central axis of the water inlet cavity 212. The water can enter the water inlet cavity 212 from the water inlet groove 22 and spray out from the water outlet nozzle 213. The water inlet cavity 212 is preferably a cavity with a circular cross-section, and the cross-section of the water inlet cavity 212 is larger than the cross-section of the water outlet nozzle 213. The side plates on both sides of the groove body of the water inlet groove 22 are the first side plate 221 and the second side plate 222 respectively. The distance from the first side plate 221 to the axis of the water inlet cavity 212 is less than the distance from the second side plate 222 to the axis of the water inlet cavity 212. The second side plate 222 is smoothly connected to the side wall of the water inlet cavity 212, that is, the distance from the first side plate 221 to the center of the cross-section of the water inlet cavity 212 is less than the radius of the cross-section of the water inlet cavity 212, while the distance from the second side plate 222 to the center of the cross-section of the water inlet cavity 212 is equal to the radius of the cross-section of the water inlet cavity 212. The second side plate 222 constitutes the tangent plane of the water inlet cavity 212.

[0036] See Figure 5and Figure 6 , the swing turning plate 52 includes a connecting ring 521 and a plurality of guiding strips 522. The connecting ring 521 is sleeved on the column 51, and the connecting ring 521 can swing on the column 51. A plurality of the guiding strips 522 protrude radially from the outer side and the inner side of the connecting ring 521 and are evenly distributed. The number of the water outlet cylinders 21 is multiple, and the positions of the multiple water inlet grooves 22 respectively correspond to the positions of the multiple guiding strips 522. The guiding strips 522 can be inserted into the water inlet grooves 22. During the process of water entering the water inlet grooves 22, the guiding strips 522 can guide the water so that it enters the water inlet grooves 22. The swing turning plate 52 can swing counterclockwise or clockwise. During the swinging process of the swing turning plate 52, the guiding strips 522 can follow the swing turning plate 52 and approach the first side plate 221 or approach the second side plate 222. In this embodiment, when the swing turning plate 52 swings counterclockwise, the guiding strips 522 approach the first side plate 221, and when the swing turning plate 52 swings clockwise, the guiding strips 522 approach the second side plate 222. The first side plate 221 and the second side plate 222 both play a role in limiting. When the swing turning plate 52 swings, the first side plate 221 and the second side plate 222 limit the swing angle range of the swing turning plate 52 by limiting the swing range of the guiding strips 522.

[0037] In order to leave space for water inlet, the width of the water inlet groove 22 is greater than the width of the guide strip 522. In this way, when the guide strip 522 is in close contact with the first side plate 221, a first flow channel 223 can be formed between the guide strip 522 and the second side plate 222, and water can enter the water inlet cavity 212 from the first flow channel 223. At this time, the water inlet direction is the tangential direction of the water inlet cavity 212. Since the tangentially entering water will form a rotating water flow in the water inlet cavity 212, under the combined action of centrifugal force and gravity, the water will be sprayed out from the water outlet nozzle 213 in the form of water droplets of granular water. Correspondingly, when the guide strip 522 is in close contact with the second side plate 222, a second flow channel 224 can be formed between the guide strip 522 and the first side plate 221, and water can enter the water inlet cavity 212 from the second flow channel 224. At this time, the water inlet direction is the central direction of the water inlet cavity 212. Since the water outlet nozzle 213 is located at the central position of the water inlet cavity 212, the water will be directly sprayed out in the form of ordinary shower water under the action of gravity. Therefore, the guide strip 522 can control the angle of water entering the water inlet cavity 212, so as to control the water droplet pattern of the water outlet. During this switching process, the water of the two water droplet patterns enters from the same water outlet cylinder 21 and is sprayed out from the same water outlet nozzle 213. Therefore, by using the swing of the guide strip 522, the effect of spraying two water droplet patterns can be achieved only by using the same layer of water inlet channel, i.e., the water inlet groove 22, and the same water outlet cylinder 21, which has the advantages of simple structure, material saving, and overall thinning of the shower head.

[0038] See Figure 7, the inclination direction of the first water diversion inclined hole 41 is opposite to that of the second water diversion inclined hole 42, and the direction of water entering the first water diversion inclined hole 41 on the inclined hole plate 6 is opposite to that of entering the second water diversion inclined hole 42. Specifically, both are oriented towards the space between the first water diversion inclined hole 41 and the second water diversion inclined hole 42, that is, the first water diversion inclined hole 41 and the second water diversion inclined hole 42 are arranged facing each other. The water on the inclined hole plate 6 can enter the water outlet cover 2 from opposite directions through the first water diversion inclined hole 41 and the second water diversion inclined hole 42. The first water diversion inclined hole 41 and the second water diversion inclined hole 42 are distributed along the circumferential direction, and both the first water diversion inclined hole 41 and the second water diversion inclined hole 42 are inclined towards the circumferential direction of the water outlet cover 2. Therefore, the water coming out of the first water diversion inclined hole 41 or the second water diversion inclined hole 42 will move towards the circumferential direction of the water outlet cover 2. In order to drive the swing turntable 52 to swing, the swing turntable 52 further includes a plurality of swing bars 523. The plurality of swing bars 523 protrude radially from the outer side and the inner side of the connecting ring 521 and are evenly distributed. The swing bars 523 are arranged between the water outlet of the first water diversion inclined hole 41 and the water outlet of the second water diversion inclined hole 42, so that water can come out of the first water diversion inclined hole 41 or the second water diversion inclined hole 42 to push the swing bars 523 to swing, and the swing bars 523 can drive the swing turntable 52 to swing counterclockwise or clockwise.

[0039] In this embodiment, referring to Figure 5 , when water enters the first water diversion inclined hole 41, under the action of the inclined hole, the water will move along the circumferential direction of the water outlet cover 2. At this time, the water will impact the swing bar 523, causing the swing bar 523 to drive the swing turntable 52 to swing counterclockwise in the direction of water movement. The guide bar 522 will follow the swing turntable 52 to swing and gradually approach the first side plate 221 to finally form the first flow channel 223. The water will enter the water outlet cylinder 21 from the first flow channel 223, thereby forming granular water jets; referring to Figure 6 , when water enters the second water diversion inclined hole 42, under the action of the inclined hole, the water will move along the circumferential direction of the water outlet cover 2. At this time, the water will impact the swing bar 523, causing the swing bar 523 to drive the swing turntable 52 to swing clockwise in the direction of water movement. The guide bar 522 will follow the swing turntable 52 to swing and gradually approach the second side plate 222 to finally form the second flow channel 224. The water will enter the water outlet cylinder 21 from the second flow channel 224, thereby forming ordinary sprinkler water jets.

[0040] Referring to Figure 8, the water distribution device 10 further includes a water distribution cover 3. The water distribution cover 3 is provided with a first inlet hole 31 and a second inlet hole 32. The first inlet hole 31 is communicated with the inner water inlet hole 11, and the second inlet hole 32 is communicated with the outer water inlet hole 12. The water entering the inner water inlet hole 11 will flow out from the first inlet hole 31, and the water entering the outer water inlet hole 12 will flow out from the second inlet hole 32. The water distribution cover 3 is further provided with a first water distribution chamber 33, a second water distribution chamber 34 and a water distribution partition 35. The first water distribution chamber 33 is communicated with the first inlet hole 31, and the second water distribution chamber 34 is communicated with the second inlet hole 32. The first water distribution chamber 33 and the second water distribution chamber 34 are isolated from each other by the water distribution partition 35. Therefore, the water entering from the inner inlet hole will not enter the second water distribution chamber 34 and will only enter the first water distribution chamber 33, and the water entering from the outer inlet hole will not enter the first water distribution chamber 33 and will only enter the second water distribution chamber 34, achieving the function of water distribution. The first water distribution chamber 33 is communicated with the first water distribution inclined hole 41, and the second water distribution chamber 34 is communicated with the second water distribution inclined hole 42. Therefore, after water distribution, see Figure 9 , the water entering from the inner inlet hole will enter from the first water distribution inclined hole 41 and push the swing turning plate 52 to swing counterclockwise. Subsequently, the water enters the water outlet cylinder 21 from the first flow channel 223 to form granular water, see Figure 10 , the water entering from the outer inlet hole enters from the second water distribution inclined hole 42 and pushes the swing turning plate 52 to swing clockwise. Subsequently, the water enters the water outlet cylinder 21 from the second flow channel 224 to form ordinary sprinkler water.

[0041] An embodiment of the present invention also provides a shower head (not shown in the figure). The shower head includes the water distribution device 10 as described above. An inlet cover 1, an inclined hole plate 6, an outlet cover 2, a switching mechanism 4, and a swinging mechanism 5 are provided on the water distribution device 10 of the shower head. The water entering from the inlet cover 1 can respectively enter the first water distribution inclined hole 41 and the second water distribution inclined hole 42 in the switching mechanism 4. When the water enters the first water distribution inclined hole 41, the impact force of the water can drive the swinging rotating plate 52 in the swinging mechanism 5 to swing around the column 51. During the swinging process, the water will enter the water outlet cylinder 21 tangentially, and the water will enter the water outlet cylinder 21 under the action of centrifugal force and be ejected from the water outlet cylinder 21. At this time, the ejected water spray is granular water; when the water enters the second water distribution inclined hole 42, the impact force of the water can drive the swinging rotating plate 52 in the swinging mechanism 5 to swing around the column 51 in the other direction. During the swinging process, the water will directly enter the water outlet cylinder 21 axially, and then be directly ejected from the water outlet cylinder 21. At this time, the ejected water spray is shower water. Therefore, the embodiment of the present invention can achieve the realization effect and switching effect of two water spray styles in a single-layer water inlet channel and a single type of water outlet cylinder structure through a refined water distribution structure. While achieving a simple structure and a relatively thin thickness, it can save material costs and production costs, is reliable in use, and can also reduce the probability of damage and maintenance.

[0042] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in the technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
