Description

Technical Field

[0001] This utility model relates to the field of spray equipment technology, and in particular to a shower head. Background Technology

[0002] A shower head, also known as a watering can, was originally a device for watering flowers, potted plants, and other plants. Later, it was modified into a shower device, making it a common bathroom item.

[0003] Some existing showerheads, such as the application document titled "showerhead" with patent application number 201711306567.1, all adopt direct spraying, that is, after the water flow from the water pipe flows to the showerhead, it is divided into branch water flow corresponding to the water outlets, and then sprayed out.

[0004] However, the water flow pattern from each nozzle of this type of shower head is too uniform, resulting in poor spraying effect. It cannot meet the needs of different usage scenarios at the same time, and only by setting more and denser nozzles can the spraying be made as even and comprehensive as possible. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a shower head that improves the water spray pattern, making the water spray more flexible, and meeting the usage needs of different scenarios.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A shower head includes a back cover, a water distribution plate, and a water outlet panel assembled in sequence, wherein the back cover and the water distribution plate form a first water distribution cavity, and the water distribution plate and the water outlet panel form a second water distribution cavity;

[0008] Several protrusions are provided on the water-facing surface of the water outlet panel. A cavity is opened through the protrusion from the top surface to the bottom surface of the water outlet panel. The opening on the top surface of the protrusion is connected to the first water distribution cavity.

[0009] A side opening is provided on the side wall of the boss to connect with the cavity, and the side opening is connected to the second water distribution cavity. Several water distribution blocks are provided on the water distribution plate to extend into the cavity. The water distribution blocks construct the cavity into two intersecting first flow channels and second flow channels. The first flow channel is connected to the first water distribution cavity, and the second flow channel is connected to the second water distribution cavity through the side opening.

[0010] Furthermore, a water distribution hole is provided on one side of the water distribution block, and the opening on the top surface of the boss communicates with the water distribution hole.

[0011] Furthermore, a sealing platform is provided at the location corresponding to the boss on the water distribution plate, and the boss and the sealing platform are connected in a sealed manner.

[0012] Furthermore, a drainage clearance groove is provided on the side of the water distribution block, and the drainage clearance groove is provided corresponding to the side opening.

[0013] Furthermore, the height of the side opening is less than half the height of the boss.

[0014] Furthermore, the water-facing surface of the water-dividing plate is provided with several water inlet grooves, and water-dividing holes are opened at the bottom of the water inlet grooves, and the water-dividing holes are connected to the cavity.

[0015] Furthermore, the side of the rear cover is provided with a water inlet channel, which is connected to the first water distribution chamber and the second water distribution chamber respectively.

[0016] Furthermore, the boss is cylindrical or cuboid.

[0017] The beneficial effects of this utility model are as follows: It provides a shower head in which a water distribution plate cooperates with the back cover and the water outlet panel to form a first water distribution cavity and a second water distribution cavity inside the shower head. The water outlet panel is provided with a boss, and the boss has a cavity. The water distribution block on the water distribution plate constructs the cavity into two intersecting first and second flow channels. When spraying, the water flow is divided into two streams and flows through the first and second water distribution cavities respectively. After flowing along the first and second flow channels respectively, they finally converge and are discharged from the water outlet panel. Each discharge position has a confluence structure composed of the first water distribution cavity, the second water distribution cavity, and the cavity. By adjusting the flow rate or water pressure of any water distribution cavity, the water outlet pattern of the shower head can be changed, making the spray pattern more flexible and meeting the usage needs of different scenarios.

[0028] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0029] Please refer to Figures 1 to 8 A shower head includes a rear cover 1, a water distribution plate 2, and a water outlet panel 3 assembled in sequence. The rear cover 1 and the water distribution plate 2 form a first water distribution cavity 4, and the water distribution plate 2 and the water outlet panel 3 form a second water distribution cavity 5.

[0030] The water outlet panel 3 has several protrusions 6 on its water-facing surface. Each protrusion 6 has a through cavity 7 extending from its top surface to the bottom surface of the water outlet panel 3. The top opening 8 of the protrusion 6 is connected to the first water distribution cavity 4. The side wall of the protrusion 6 has a side opening 9 that connects to the cavity 7 and is connected to the second water distribution cavity 5.

[0031] The water distribution plate 2 is provided with a plurality of water distribution blocks 10 extending into the cavity 7. The water distribution blocks 10 construct the cavity 7 into two intersecting first flow channels 11 and second flow channels 12. The first flow channel 11 is connected to the first water distribution cavity 4, and the second flow channel 12 is connected to the second water distribution cavity 5 through the side opening 9.

[0032] As can be seen from the above description, the beneficial effects of this utility model are as follows: Inside the shower head, the water distribution plate 2 cooperates with the rear cover 1 and the water outlet panel 3 to form a first water distribution cavity 4 and a second water distribution cavity 5, respectively. A boss 6 is provided on the water outlet panel 3, and the boss 6 has a cavity 7. The water distribution block 10 on the water distribution plate 2 constructs the cavity 7 into two intersecting first flow channels 11 and second flow channels 12. During spraying, the water flow is divided into two streams and flows through the first water distribution cavity 4 and the second water distribution cavity 5 respectively, then flows along the first flow channel 11 and the second flow channel 12 respectively, and finally converges and is discharged from the water outlet panel 3 along the cavity 7. Each discharge position has a confluence structure composed of the first water distribution cavity 4, the second water distribution cavity 5, and the cavity 7. By changing the flow rate or water pressure of any one water distribution cavity, the water outlet pattern of the shower head can be changed, making the spray pattern more flexible and meeting the usage needs of different scenarios. At the same time, by constructing a boss on the water outlet plate, the available space of the required cavity is increased, providing sufficient space for the interaction of fluids within the cavity. In addition, the space between the protrusions can be shared as a water inlet and storage channel, avoiding the layout cost of a separate channel and increasing the uniformity and stability of the water output.

[0033] Furthermore, when two water streams with different flow angles collide, if one stream is stronger than the other (i.e., has a larger flow rate), the outflow trajectory of the collided fluid will tend to follow the larger flow rate. When the two branch fluids from the first channel 11 and the second channel 12 collide, both a confluence effect and fluid particles are generated, and the splashing direction of the fluid particles is mainly towards both sides perpendicular to the water flow direction. A cavity 7 is provided in the outflow direction of the channel to limit the splashing of fluid particles and to re-converge the fluid particles with the converging fluids, thereby affecting the outflow direction and shape.

[0034] Furthermore, a water distribution hole 13 is provided on one side of the water distribution block 10, and the opening 8 on the top surface of the boss 6 is connected to the water distribution hole 13.

[0035] As can be seen from the above description, a water distribution hole 13 is opened on the side of the water distribution channel so that the first flow channel 11 can be accurately connected to the first water distribution cavity 4 at the same time as it is formed, thereby improving the tightness of the fit between the components.

[0036] Furthermore, a sealing platform 14 is provided at the corresponding position of the water distribution plate 2 and the boss 6, and the boss 6 and the sealing platform 14 are sealed together.

[0037] As can be seen from the above description, by setting the sealing platform 14 to be aligned and fitted with the boss 6, the cavity 7 of each boss 6 is ensured to be independent, and water flow other than directly from the first flow channel 11 and the second flow channel 12 is prevented from flowing into the cavity 7.

[0038] Furthermore, a drainage clearance groove 15 is provided on the side of the water distribution block 10, and the drainage clearance groove 15 is correspondingly provided with the side opening 9.

[0039] As can be seen from the above description, by opening a drainage clearance groove 15 corresponding to the side opening 9, a flow clearance space is provided for the water flow from the second water distribution chamber 5, so as to avoid the situation where the water flow from the side opening 9 is affected by the width of the flow channel, resulting in too little water for the water flow to meet the water flow of the first flow channel 11.

[0040] Furthermore, the height of the side opening 9 is less than half the height of the boss 6.

[0041] As can be seen from the above description, the height of the side opening 9 is less than half the height of the boss 6, so as to avoid the water flow from the second water distribution cavity 5 and the water flow from the side directly impacting the water flow in the first flow channel 11 and affecting the final water outflow effect; at the same time, it ensures that a certain water passage space is formed in the cavity 7 to ensure the water constraint and rectification effect.

[0042] Furthermore, the water-facing surface of the water-dividing plate 2 is provided with several water inlet grooves 16, and water-dividing holes 13 are opened at the bottom of the water inlet grooves 16, and the water-dividing holes 13 are connected to the cavity 7.

[0043] As can be seen from the above description, a water inlet groove 16 is provided on the water-facing surface of the water distribution plate 2. The water inlet groove 16 guides the water flow to initially converge and then pours into the water distribution hole 13, thereby increasing the water flow speed at the water distribution hole 13.

[0044] Furthermore, the side of the rear cover 1 is provided with a water inlet channel 17, which is connected to the first water distribution chamber 4 and the second water distribution chamber 5 respectively.

[0045] As can be seen from the above description, placing the water inlet channel 17 on the side of the rear cover 1 can reduce the space requirement for the internal flow channel layout of the shower head to a certain extent.

[0046] Furthermore, the boss 6 is cylindrical or cuboid.

[0047] As described above, designing the boss 6 as a cylinder or cuboid improves assembly convenience. A cylinder enhances sealing, while a cuboid increases density.

[0048] Please refer to Figure 1 and Figure 2 Embodiment 1 of this utility model is as follows:

[0049] A shower head includes a rear cover 1, a water distribution plate 2, and a water outlet panel 3 assembled sequentially. The rear cover 1 and the water distribution plate 2 form a first water distribution cavity 4, and the water distribution plate 2 and the water outlet panel 3 form a second water distribution cavity 5. Several protrusions 6 are provided on the water-facing surface of the water outlet panel 3. The protrusions 6 have a through cavity 7 extending from the top surface to the bottom surface of the water outlet panel 3. The top opening 8 of the protrusion 6 communicates with the first water distribution cavity 4. The side wall of the protrusion 6 has a side opening 9 that communicates with the cavity 7. The side opening 9 communicates with the second water distribution cavity 5. Several water distribution blocks 10 extending into the cavity 7 are provided on the water distribution plate 2. The water distribution blocks 10 construct the cavity 7 into two intersecting first flow channels 11 and second flow channels 12. The first flow channel 11 communicates with the first water distribution cavity 4, and the second flow channel 12 communicates with the second water distribution cavity 5 through the side opening 9.

Figure 2 As indicated by arrow L1, another portion flows into the second water distribution chamber 5, forming a second stream of water, with its flow direction as shown in the image. Figure 2 As shown by arrow L2 in the diagram; the first stream of water flows through the opening 8 on the top surface of the boss 6 and into the first flow channel 11 of the cavity 7, while the second stream of water flows through the side opening 9 and into the second flow channel 12 of the cavity 7; inside the cavity 7, the first stream of water and the second stream of water converge and collide, and finally discharge together from the discharge port located at the bottom of the water outlet panel 3 connected to the cavity 7.

[0052] To better control the convergence of the first and second water flows, a water-dividing hole 13 is provided on one side of the water-dividing block 10, and the opening 8 on the top surface of the boss 6 is connected to the water-dividing hole 13. It should be noted that there can be one or more first water-dividing chambers 4 and second water-dividing chambers 5, and each first water-dividing chamber 4 and second water-dividing chamber 5 can be connected to one or more chambers 7.

[0053] The first water-dividing cavity 4 can be formed by a slot on the back cover 1 and / or a slot on the water-facing surface of the water-dividing plate 2, while the second water-dividing cavity 5 can be formed by a slot on the back surface of the water-dividing plate 2 and / or a slot on the inward-facing side of the water outlet panel 3.

[0054] Furthermore, a drainage clearance groove 15 is provided on the side of the water distribution block 10, and the drainage clearance groove 15 is correspondingly provided with the side opening 9. The drainage clearance groove 15 serves as the drainage cavity 7, forming a conversion space connecting the side opening 9 and the second water distribution cavity 5.

[0056] A shower head, based on the above-described embodiment one, has a sealing platform 14 provided at the corresponding position of the water distribution plate 2 and the boss 6, and the boss 6 and the sealing platform 14 are sealed together. Preferably, the boss 6 is shaped as follows: Figure 5 The cylinder shown or Figure 7 and Figure 8 The cuboid shown can be replaced by a boss 6 in other embodiments, which may also be other three-dimensional structures such as a trapezoidal platform. Figure 3 and Figure 5 As shown, the shape and size of the sealing platform 14 are adapted to the boss 6; during assembly, the two are aligned vertically.

[0057] Furthermore, in order to create a certain water passage space in the cavity 7 and ensure the water confinement and rectification effect, the height of the side opening 9 is less than the height of the boss 6. Preferably, the height of the side opening 9 is less than half the height of the boss 6.
