Description

Technical Field

[0001] The present invention relates to the field of bathroom fixtures, and in particular to a water outlet panel and a water outlet device. Background Art

[0002] In order to enrich the water-discharging functions of existing bathroom products, various functional components are added to the bathroom products, such as enabling the bathroom products to produce bubble water, blade water, massage water, granular water, etc. For example, Chinese patent document No. CN102210988A discloses a bubbler, which includes a body (100), a diverter (200) and an insert (300). The diverter (200) and the insert (300) are installed in the body (100). The body (100) is provided with an air intake hole (110) that penetrates inside and outside. The water flow is affected by the diverter (200) to form a jet, and the jet collides with the insert (300) to produce an atomization effect, and the jet is atomized by the air intake. The air sucked in by the hole (110) is mixed, and the insert (300) includes a plurality of bottom baffles (310), a plurality of middle baffles (320) and a plurality of upper convex columns (330) fixed together, and channels (340) are formed between adjacent bottom baffles (310) and adjacent middle baffles (320). The collision surface of the upper convex columns (330), the collision surface of the middle baffles (320) and the collision surface of the bottom baffles (310) form three layers spaced along the direction (X). Due to the arrangement of the three layers of collision surfaces, the water flow enters the insert and collides to form granular water. However, due to the arrangement of the three layers of collision surfaces, the volume of the overall structure of the bubbler is large, and due to the position design of the collision surfaces, the number of water spray forms that can be formed by the bubbler is small, which cannot meet the user's more usage needs.

[0003] In addition, the air intake hole in the bubbler made by the above patent is located on the side wall of the main body, and the water flow area of the insert is large, so that the negative pressure generated in the inner cavity when the water flows through the insert is insufficient, resulting in insufficient air intake, and thus the atomization effect of the granular water is poor. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a water outlet panel and a water outlet device to improve the atomization effect of granular water.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A water outlet panel includes a first water passing member and a water retaining portion; the first water passing member has a water spray forming cavity therein;

[0007] The water retaining portion is provided on a side of the first water passing member axially away from the water spray forming cavity, and an axial projection area of the water spray forming cavity is located on the water retaining portion, so that a water flow channel distributed along the circumference of the first water passing member is formed between the water retaining portion and the inner wall of the water spray forming cavity;

[0008] The first water flow member is provided with a first flow-disturbing column and a water flow groove communicating with the water flow channel;

[0009] In the radial direction of the first water-passing member, the first flow-spreading column is directly opposite to the water-passing groove, so that a flow-spreading channel is formed between the circumferential side wall of the first flow-spreading column and the inner wall of the water-passing groove;

[0010] The inner diameter of the water spray forming cavity gradually increases in a direction away from the water retaining portion.

[0011] The first water flow member has at least two water flow columns therein, and a water flow groove is provided between every two adjacent water flow columns, and the side walls of the water flow columns constitute the inner walls of the water flow groove.

[0012] In order to solve the above technical problems, another technical solution adopted by the present invention is:

[0013] A water outlet device comprises the water outlet panel described in the above technical solution.

[0014] The beneficial effect of the present invention is that: due to the provision of the first spoiler post, the water flow is divided into two water flows in the water flow chamber, and the divided water flows flow into the water flow channel from the spoiler channel. When a plurality of first spoiler posts and water flow channels are provided, the water flows divided by adjacent first spoiler posts collide with each other and then flow into the water spray forming chamber from the water flow channel. During the mutual impact of the water flows, granular water is formed, and the water flows flowing through different water flow channels also collide in the water spray forming chamber, so that the water flows are completely formed into granular water. When only one first spoiler post and water flow channel is provided, the water flows divided by the spoiler post collide in the spoiler channel, generating some granular water, and the other part collides with the inner wall of the water spray forming chamber after entering the water flow channel, thereby completely forming granular water. The water flow area of the spray-forming cavity gradually increases as it moves away from the water retaining portion. This sudden increase in the water flow area creates negative pressure, which draws air in from the outlet side of the spray-forming cavity and mixes with the water flow, atomizing the granular water. The air drawn in from the outlet side of the spray-forming cavity hinders the discharge of the water flow and creates a pulsating effect. The formation of the granular water of the present invention conserves water, increases the air content in the granular water, and ensures its impact, providing a strong stain-washing function.

[0033] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0034] Please refer to Figures 1-11 A water outlet device includes a water outlet panel, which is connected to the water outlet device in a relatively flippable manner; the water outlet panel includes a first water flow member 1, a second water flow member 2 and a water retaining portion 3; the second water flow member 2; in the axial direction of the first water flow member 1, the second water flow member 2 is arranged opposite to the first water flow member 1 and forms a water flow cavity 21; the first water flow member 1 has a water splash forming cavity 11; the water retaining portion 3 is provided on the side of the first water flow member 1 away from the water splash forming cavity 11 in the axial direction, and the axial projection area of the water splash forming cavity 11 is The first water-forming cavity 11 is provided with a first spoiler 5 and a water channel 6 connected to the water channel 4. The first water-forming cavity 11 is provided with a first spoiler 5 and a water channel 6 connected to the water channel 4. In the radial direction of the first water-forming cavity 1, the first spoiler 5 is directly opposite the water channel 6, so that a spoiler channel 61 is formed between the circumferential sidewall of the first spoiler 5 and the inner wall of the water channel 6. The inner diameter of the water-forming cavity 11 gradually increases in a direction away from the water-forming cavity 3. The phrase "directly opposite the first spoiler 5 and the water channel 6" means that in the radial direction of the first water-forming cavity 1, the projected area of the first spoiler 5 is located within the projected area of the water channel 6.

[0035] It is understandable that, due to the setting of the first spoiler post 5, water current is divided into two streams in water chamber 21, and the water current after being divided then flows into the water trough 6 from spoiler channel 61. When the first spoiler post 5 and water trough 6 are provided with a plurality of times, then the water current after being divided by adjacent first spoiler post 5 impacts each other after flowing into the water flower forming chamber 11 from water trough 6, in the process that water current impacts each other, granular water forms, and the water current flowing through different water troughs 6 also can clash in the water flower forming chamber, and water current is formed granular water completely; When the first spoiler post 5 and water trough 6 are only provided with one, then the water current after being divided by the spoiler post impacts in spoiler channel 61, produces part granular water, and it and part then enter the water trough 6 after along with water current and clash with the inwall of the water flower forming chamber, and then thoroughly forms granular water. The water flow area of the water spray forming cavity 11 will gradually increase in the direction away from the water retaining portion 3. Due to the sudden increase in the water flow area, negative pressure is generated. The formation of negative pressure causes air to be sucked in from the water outlet side of the water spray forming cavity 11 and mixed with the water flow, thereby realizing the atomization of granular water. The air sucked in from the water outlet side of the water spray forming cavity 11 has an obstructive effect on the discharge of the water flow, and can also make the discharge of the water flow form a certain pulsation, that is, the discharge of the water spray is intermittent, which is also conducive to rinsing away dirt.

[0036] In some embodiments, the first water flow member 1 has at least two water flow columns 16 , and there is a water flow groove 6 between every two adjacent water flow columns 16 . The provision of multiple water flow columns 16 can divide the water flow more evenly and ensure the formation of the water flow groove 6 .

[0037] In some embodiments, the water splash forming cavity 11 has a water inlet 111, a water outlet 112 and a water outlet 113 arranged in sequence along the direction away from the water retaining portion 3; the inner diameter of the water inlet 111 is smaller than the inner diameter of the water outlet 112, and the inner diameter of the water outlet 112 is smaller than the inner diameter of the water outlet 113.

[0038] In some embodiments, all water flow columns 16 form an inner water inlet grille, and the water splash forming cavity 11 has a first water flow area 12 and a second water flow area 13 arranged in sequence along a direction gradually away from the water retaining portion 3. In the radial direction of the first water flow part 1, the width of the first water flow area 12 is smaller than the width of the second water flow area 13.

[0039] In a possible embodiment, the first water flow area 12 and the second water flow area 13 are both located in the water flow chamber 21. Specifically, the water flow column 16 is located in the water flow chamber 21, and the first water flow area 12 is located on the inner wall of the inner water inlet grille; the second water flow area 13 is located at the water inlet 111 of the water spray forming chamber 11, wherein two water flow grooves 6 can be formed between the three water flow columns 16, and the same stream of water will flow out from the two adjacent water flow grooves 6 after being diverted by the spoiler column. Since the width of the first water flow area 12 (that is, the inner diameter of the inner water inlet grille) is smaller than the width of the second water flow area 13, the first water flow area 12 is located between the three water flow columns 16 arranged in sequence. When the water flow flows from the first water flow area 12 into the second water flow area 13, the water flow area of the water flow changes, thereby generating negative pressure, and air is sucked into the water flow chamber 21 and mixed with the water flow, so that the formed granular water contains gas, thereby improving the softness of the granular water.

[0040] In another possible embodiment, the first water flow area 12 and the second water flow area 13 are both located in the water spray forming cavity 11; specifically, the first water flow area 12 and the second water flow area 13 are respectively located in the water inlet 111 and the water flow area 112, or the first water flow area 12 and the second water flow area 13 are respectively located in the water flow area 112 and the water outlet 113, or the first water flow area 12 and the second water flow area 13 are respectively located in the water inlet 111 and the water outlet 113.

[0041] In a third possible embodiment, the first water flow area 12 is located in the water flow chamber 21, and the second water flow area 13 is located in the water spray forming chamber 11. Specifically, the first water flow area 12 is located between three water flow columns 16 arranged in sequence, and the second water flow area 13 is located on the water inlet 111, the water flow outlet 112 or the water outlet 113.

[0042] In some embodiments, it also includes a third water flow area 14 and a fourth water flow area 15 which are arranged in sequence along the direction gradually away from the water retaining portion 3, that is, along the direction gradually away from the water retaining portion 3, the first water flow area 12, the second water flow area 13, the third water flow area 14 and the fourth water flow area 15 are arranged in sequence, and wherein, the width W of the first water flow area 12> the width D of the second water flow area 13> the width L of the third water flow area 14> the width K of the fourth water flow area 15, so that the water flow passes through multiple sudden changes in the water flow area. In each sudden change in the water flow area, negative pressure will be generated in the sudden change area, and a certain amount of air will be inhaled to disturb the discharge of the water flow, thereby forming pulsating water, so that the decontamination effect of the final water splash is improved.

[0043] In some embodiments, the inner wall of the water column 16 gradually tilts away from the water splash forming cavity 11 in the direction away from the water retaining portion 3, so that the width of the first water flow area 12 gradually increases in the direction away from the water retaining portion 3, achieving the effect of the water flow area changing from small to large, thereby improving the suction effect.

[0044] In some embodiments, a second spoiler column 7 is further included; the first spoiler column 5 and the second spoiler column 7 are arranged in sequence along the circumference of the first water flow member 1, and the second spoiler column 7 is located between every two adjacent first spoiler columns 5; in the circumferential direction of the first water flow member 1, a water flow channel connected to the spoiler channel 61 is formed between the first spoiler column 5 and the second spoiler column 7; the arrangement of the second spoiler column 7 can further break up the water flow and improve the collision effect of the water flow.

[0045] In some embodiments, all water columns 16 form an inner water inlet grille, and the water retaining portion 3 is fixed to or placed on the inner water inlet grille in the form of a cover plate 8. When the cover plate 8 is fixed to the inner water inlet grille, it can guide the water flow through the space formed between the water trough 6 and the cover plate 8, so that all water flows only through the water trough 6 into the water spray forming cavity 11, improving the impact effect of the water flow, that is, improving the formation effect of the granular water and increasing the outlet pressure and density of the granular water. In contrast, when the cover plate 8 is only placed on the inner water inlet grille, most of the water flow can still flow through the space formed between the water trough 6 and the cover plate 8, but a small amount of water flow will flow into the water spray forming cavity 11 through the gap between the end surface of the water column 16 and the cover plate 8. This solution has a poorer granular water forming effect, but the structural requirements are lower. As long as the height of the gap is reasonably controlled and the flow rate through the gap is controlled to within 20% of the flow rate through the water trough 6, the final formed granular water quality can meet the most basic requirements. As an improvement to this embodiment, in order to supplement the flow rate, small holes can be provided on the cover plate 8 to allow water to flow through the small holes axially into the water spray forming cavity 11, but the sum of the flow rate passing through the gap and the flow rate flowing through the small holes must also be controlled to be less than 20% of the flow rate passing through the water trough 6.

[0046] In some embodiments, a diversion slope 18 is provided between the water trough 6 and the water inlet 111 of the water spray forming chamber 11. The diversion slope 18 gradually slopes away from the water retaining portion 3 along the direction from the water trough 6 to the water inlet 111. After most of the water flows through the water trough 6, it will collide with the first water flow member 1 in the radial direction, thereby generating granular water. At the same time, the remaining water flows along the diversion slope 18 and collides with the water spray forming chamber 11, thereby generating granular water. The setting of the diversion slope 18 creates a time difference between the two parts of granular water being discharged from the water spray forming chamber 11, thereby causing the water flow to pulsate. The granular water finally formed will have a pulsating function, thereby improving the cleaning effect of the granular water. Generally, the inclination angle α of the diversion slope 18 is less than 45°; more preferably, the inclination angle α is between 15° and 30°, which can produce the best granular water forming effect.

[0047] In some embodiments, a sealing member 9 is also included; a water replenishment channel 17 is also provided on the first water flow member 1, and the water replenishment channel 17 is distributed along the circumference of the first water flow member 1; when the first water flow member 1 serves as the water inlet surface, the water replenishment channel 17 can be used to replenish the water flow and increase the water intake. When the first water flow member 1 serves as the water outlet surface, the sealing member 9 is pressed against the water replenishment channel 17, so that the water flow must pass through the water trough 6 and the water splash forming cavity 11 before being discharged, ensuring the formation of the granular water. In addition, the sealing member 9 blocks the water replenishment channel 17 and can also play a pressurizing role, so that the granular water column obtains greater impact force.

[0048] In some embodiments, a flow straightener 10 is further included; the flow straightener 10 is disposed within the water passage cavity 21. When the water retaining portion 3 serves as the water outlet, the sealing member 9 presses against the flow straightener 10, allowing the water supply channel 17 to communicate with the water spray forming cavity 11. When the first water passage 1 serves as the water outlet, the flow straightener 10 presses against the cover plate 8. When the first water passage 1 serves as the water inlet, the flow straightener 10 supports the sealing member 9, allowing the water supply channel 17 to open, while preventing the sealing member 9 from blocking the water outlet hole on the second water passage 2. In addition, the water retaining portion 3 can be arranged on the rectifying member 10 or on the second water passing member 2. Specifically, in one embodiment, when the water retaining portion 3 is arranged on the rectifying member 10 and the first water passing member 1 serves as the water outlet surface, the water flow channel 4 is also located on the rectifying member 10. At this time, the rectifying member 10 plays a diversion role, ensuring that the water flow can flow through the water trough 6 and then enter the water splash forming cavity 11, thereby ensuring the forming effect of the granular water. In another embodiment, the water retaining portion 3 can also be arranged on the second water passing member 2. Correspondingly, the water flow channel 4 is also located on the second water passing member 2 and distributed along the circumference of the water retaining portion 3. In a third embodiment, the second water passing member 2 can also be a closed structure, and a water hole is opened on the circumferential side wall of the water outlet panel, and the water flow channel 4 is located in the water hole. In other embodiments, regardless of whether the water retaining portion 3 is arranged on the rectifying member 10 or the second water flow member 2, a small hole can be opened in the water retaining portion 3 to supplement the water flow, but the diameter of the small hole should not be too large to ensure that the main water flow can flow through the water flow channel 4 and through the water tank 6.

[0049] In some embodiments, an external water inlet grille 20 is further included; the external water inlet grille 20 is arranged around the axis of the first water pass member 1; in the radial direction of the first water pass member 1, the external water inlet grille 20 is located between the water supply channel 17 and the internal water inlet grille; the setting of the external water inlet grille 20 plays a role in preliminary diversion of the water flow.

[0050] In some embodiments, the fairing 10 is a floating structure, that is, the fairing 10 can change its position in the axial direction of the water outlet panel as the water outlet panel is flipped. Specifically, a limiting platform 22 is provided on the side of the second water pass 2 facing the first water pass 1. The limiting platform 22 is used to support the fairing 10. When the second water pass 2 serves as the water outlet surface, the fairing 10 will be pressed against the limiting platform 22, so that a distance is maintained between the fairing 10 and the water pass surface of the second water pass 2.

[0051] In some embodiments, a third spoiler 30 is further included; one third spoiler 30 is disposed in each water channel 6, and the third spoiler 30 is centrally located within the water channel 6 in the circumferential direction of the first water channel 1. The third spoiler 30 is provided to further disperse the water flow.

[0052] In some embodiments, six water-passing columns 16 are evenly distributed along the circumference. In the axial direction of the first water-passing member 1, the total water-passing area of the plurality of water-passing columns 16 is smaller than the cross-sectional area of the entrance to the water-spray-forming cavity 11. This design facilitates smoother discharge of water entering the water-spray-forming cavity 11, resulting in an optimal water-spray pattern.

[0053] In some embodiments, six water-passing columns 16 are evenly distributed along the circumference. In the axial direction of the first water-passing member 1, the water-passing area S at the outlet of the water channel 6 (referring to the water-passing area formed between any two adjacent water-passing columns at the outlet of the water channel) is 50% to 60% of the water-passing area A of the flow-disrupting channel 61. Optimally, this ratio can be designed to be 55%. The principle of this design is to allow water flow to enter the crowded water channel 6 from the loose flow-disrupting channel 61, thereby allowing the water flow to better collide with each other before entering the water channel 6, thereby facilitating the formation of an optimal water splash.

[0054] Please refer to Figure 1-Figure 7 , embodiment 1 of the present invention is:

[0055] A water outlet device includes a water outlet panel, which is connected to the water outlet device in a relatively flippable manner; the water outlet panel includes a first water flow member 1, a second water flow member 2, and a water retaining portion 3; the second water flow member 2 is arranged opposite to the first water flow member 1 in the axial direction of the first water flow member 1; the first water flow member 1 has a water spray forming cavity 11; the water retaining portion 3 is provided on the side of the first water flow member 1 away from the water spray forming cavity 11 in the axial direction, and the axial projection area of the water spray forming cavity 11 is located on the water retaining portion 3 On the top, a water flow channel 4 distributed along the circumference of the first water flow member 1 is formed between the water retaining portion 3 and the inner wall of the water splash forming cavity 11; twelve first spoiler columns 5 and six water flow grooves 6 connected to the water flow channel 4 are provided in the first water flow member 1; in the radial direction of the first water flow member 1, the first spoiler columns 5 are opposite to the water flow grooves 6, so that a spoiler channel 61 is formed between the circumferential side wall of the first spoiler columns 5 and the inner wall of the water flow grooves 6; the inner diameter of the water splash forming cavity 11 gradually increases in the direction away from the water retaining portion 3.

[0056] In this embodiment, the first spoiler columns 5 and the second spoiler columns 7 are arranged sequentially along the circumference of the first water flow passage 1, and the second spoiler columns 7 are located between every two adjacent first spoiler columns 5; in the circumferential direction of the first water flow passage 1, a water flow channel connected to the spoiler channel 61 is formed between the first spoiler columns 5 and the second spoiler columns 7.

[0057] In this embodiment, the water flow chamber 21 and the water splash forming chamber 11 have a first water flow area 12, a second water flow area 13, a third water flow area 14 and a fourth water flow area 15, which are arranged in sequence along the direction gradually away from the water retaining portion 3, wherein the width of the first water flow area 12 > the width of the second water flow area 13 > the width of the third water flow area 14 > the width of the fourth water flow area 15; the water splash forming chamber 11 has a water inlet 111, a water flow port 112 and a water outlet 113, which are arranged in sequence along the direction away from the water retaining portion 3; the inner diameter of the water inlet 111 is smaller than the inner diameter of the water flow port 112, and the inner diameter of the water flow port 112 is smaller than the inner diameter of the water outlet 113. The water flow column 16 is located in the water flow cavity 21 , the first water flow area 12 is located on the inner wall of the inner water inlet grille; the second water flow area 13 is located in the water inlet 111 ; the third water flow area 14 is located in the water flow outlet 112 ; and the fourth water flow area 15 is located in the water outlet 113 .

[0058] In this embodiment, the first water flow member 1 has six water flow columns 16 , with a water flow groove 6 between every two adjacent water flow columns 16 , and the inner walls of the water flow columns 16 gradually tilt away from the water spray forming cavity 11 in the direction away from the water retaining portion 3 .

[0059] In this embodiment, there is a diversion slope 18 between the water trough 6 and the water inlet 111 of the water spray forming cavity 11. The diversion slope 18 gradually tilts away from the water retaining portion 3 along the direction from the water trough 6 to the water inlet 111, and the inclination angle α is 20°.

[0060] In this embodiment, a sealing member 9 and a flow regulating member 10 are also included. The first water passage 1 is also provided with a water replenishment channel 17, which is distributed along the circumference of the first water passage 1. When the first water passage 1 serves as the water outlet, the sealing member 9 presses against the water replenishment channel 17; when the first water passage 1 serves as the water inlet, the sealing member 9 presses against the flow regulating member 10. The water retaining portion 3 and the water flow channel 4 are both provided on the flow regulating member 10, with the water flow channel 4 surrounding the water retaining portion 3.

[0061] In this embodiment, an outer water inlet grille 20 is further included; the outer water inlet grille 20 is arranged around the axis of the first water flow member 1; in the radial direction of the first water flow member 1, the outer water inlet grille 20 is located between the water supply channel 17 and the inner water inlet grille.

[0062] The working principle of this embodiment is:

[0063] When the first water-passing member 1 serves as the water outlet, the water flows through the second water-passing member 2 and the water-passing channel 4 on the rectifying member 10 in sequence, and is then dispersed by the first and second spoiler columns 5 and 7. The dispersed water flows from the spoiler channel 61 through the end of the water trough 6 away from the central water-passing cavity 21, and finally enters the water-splash forming cavity 11 through the water trough 6.

[0064] The water flowing through the water trough 6 collides with each other to form granular water, which is then discharged from the water spray forming cavity 11. Part of the water flows directly into the first water flow member 1 in the radial direction to form granular water, while the other part of the water flows along the guide slope and enters the water spray forming cavity 11 and collides to form granular water. Due to the spatial difference between the two parts of granular water, there is a time difference when they are discharged from the water spray forming cavity 11, resulting in water flow pulsation.

[0065] When the second water flow part 2 serves as the water outlet surface, the sealing member 9 is pressed against the rectifying member 10, the water replenishment channel 17 is opened, and the water flows through the water replenishment channel 17 and the water flow channel 4 located on the rectifying member 10 in sequence and is discharged from the water flow surface of the second water flow part 2, forming fine water.
