Description

Technical Field

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

[0002] In the field of bathroom fixtures, the showerhead, as a key component in showers, faucets, and other devices used to output water flow, directly impacts the user experience. Among these, the water pressure of the showerhead is a crucial performance indicator. Appropriate water pressure ensures that the water flow has sufficient impact and coverage to meet the user's needs for cleaning their body and hair, and provides a comfortable bathing experience.

[0003] However, some showerheads have poorly designed internal water flow channels, leading to significant resistance during water flow and substantial water pressure loss. Other showerheads incorporate complex filtration devices or components to perform other functions, such as filtering impurities. These components occupy internal space, reducing the effective flow space and further exacerbating resistance, resulting in lower water pressure. In actual use, when the water pressure is low, the water jet is dispersed and weak, failing to form a strong, concentrated stream. This makes it difficult for users to effectively clean their skin, reducing cleaning effectiveness. Furthermore, the weak water flow lacks the impact of a strong, massaging water jet, significantly reducing user comfort during showering. This insufficient water pressure is particularly noticeable for users with high expectations for their showering experience, severely impacting their evaluation of the product. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a sprinkler head that, by forming a pressurizing chamber between the pressurizing plate and the water outlet plate, utilizes the principle of water flow compression and pressurization to effectively increase the water pressure at the outlet, solving the problem of insufficient water pressure in traditional sprinkler heads, significantly enhancing the user's water comfort, and is simple in structure, low in cost, and easy to manufacture and promote.

[0005] This utility model also proposes a shower assembly having one of the above-mentioned nozzles.

[0006] A nozzle according to this utility model includes: Base shell; A water collection cylinder is located in the middle of the base shell. One end of the water collection cylinder is used for water inlet, and the other end is provided with a water outlet groove. A water outlet plate is disposed on the base shell and located on the side of the water outlet trough away from the center of the water collection cylinder; A pressure boosting plate is disposed inside the base shell and located on the side of the water outlet plate facing the center of the water collection cylinder. The pressure boosting plate is arranged around the water outlet groove. The inner circumferential surface of the pressure boosting plate abuts against the water collection cylinder, and the outer circumferential surface of the pressure boosting plate abuts against the base shell to form a pressure boosting cavity between the pressure boosting plate and the water outlet plate. The end face of the water outlet plate is provided with multiple water outlet holes for spraying water outward.

[0007] According to the present invention, a nozzle has at least the following beneficial effects: A water collecting cylinder is disposed in the middle of the base shell, with a water inlet at one end and a water outlet at the other, serving to guide the water flow. Furthermore, a water outlet plate is located on the side of the water outlet groove away from the center of the water collecting cylinder, with multiple water outlet holes distributed on its end face for spraying water outwards. Additionally, a pressure boosting plate is disposed inside the base shell and on the side of the water outlet plate facing the center of the water collecting cylinder, arranged around the water outlet groove. Its inner circumferential surface abuts against the water collecting cylinder, and its outer circumferential surface abuts against the base shell, thus forming a pressure boosting cavity between the pressure boosting plate and the water outlet plate. In application, when water flows in from the water collecting cylinder, it first enters this relatively enclosed and small-space pressure boosting cavity. Based on fluid mechanics principles, when water flows within a smaller pressurization chamber, the cross-sectional area of ​​the flow channel decreases, the water velocity increases, and the pressure rises. This is analogous to squeezing a certain amount of water into a smaller space, naturally increasing the water pressure. Consequently, water that might otherwise have insufficient pressure due to pipe resistance receives effective pressure compensation. When this pressure is released from the multiple water outlets on the end face of the water tray, it has higher pressure, allowing for a stronger and more concentrated spray. This effectively solves the problem of insufficient water pressure in traditional showerheads, greatly improving user comfort and providing a more impactful and effective cleaning experience. Simultaneously, the multiple dispersed water outlets ensure even water distribution, further enhancing the bathing experience.

[0008] According to some embodiments of the present invention, in a nozzle, the two sides of the pressure plate are welded and fixed to the water collection cylinder and the base shell, respectively.

[0009] According to some embodiments of the present invention, the pressure plate, the base shell, and the water collection cylinder are all made of metal.

[0010] According to some embodiments of this utility model, in a nozzle, the two sides of the pressure plate are respectively sealed to the water collection cylinder and the base shell.

[0011] According to some embodiments of the present invention, in a nozzle, the inner periphery of the pressure plate is welded and fixed to the water collection cylinder by an annular weld bead, and the outer periphery of the pressure plate is welded and fixed to the base shell by an annular weld bead.

[0012] According to some embodiments of the present invention, a nozzle is provided with reinforcing ribs on the surface of the pressure plate.

[0013] According to some embodiments of this utility model, in the thickness direction of the water outlet plate, the maximum width of the pressurizing chamber is A, which satisfies A≤10mm.

[0014] According to some embodiments of the present invention, in a nozzle, the water outlet plate is welded and fixed to the base shell.

[0015] According to some embodiments of the present invention, a nozzle is provided in which multiple nozzles are distributed on the end face of the water outlet plate, and the water outlet hole is disposed on the nozzle.

[0016] The shower assembly according to this utility model includes a spray head as described in this utility model.

[0017] The shower assembly according to this utility model has at least the following beneficial effects: by integrating the optimized nozzle into the shower assembly, the entire shower system can fully utilize the pressurization advantage of the nozzle, providing users with a more comfortable and convenient shower experience. In application, users can enjoy the strong and uniform water flow impact provided by the nozzle, thus improving the overall quality of the shower.

[0026] In the field of bathroom fixtures, the showerhead, as a key component in showers, faucets, and other devices used to output water flow, directly impacts the user experience. Among these, the water pressure of the showerhead is a crucial performance indicator. Appropriate water pressure ensures that the water flow has sufficient impact and coverage to meet the user's needs for cleaning their body and hair, and provides a comfortable bathing experience.

[0027] However, some showerheads have poorly designed internal water flow channels, leading to significant resistance during water flow and substantial water pressure loss. Other showerheads incorporate complex filtration devices or components to perform other functions, such as filtering impurities. These components occupy internal space, reducing the effective flow space and further exacerbating resistance, resulting in lower water pressure. In actual use, when the water pressure is low, the water jet is dispersed and weak, failing to form a strong, concentrated stream. This makes it difficult for users to effectively clean their skin, reducing cleaning effectiveness. Furthermore, the weak water flow lacks the impact of a strong, massaging water jet, significantly reducing user comfort during showering. This insufficient water pressure is particularly noticeable for users with high expectations for their showering experience, severely impacting their evaluation of the product.

[0028] Therefore, such as Figures 1 to 3As shown, this utility model proposes a nozzle, which includes a base shell 100, a water collection cylinder 200 disposed on the base shell 100, a water outlet plate 300 disposed on the base shell 100, and a pressure boosting plate 400 disposed on the base shell 100. The water collection cylinder 200 is disposed in the middle of the base shell 100. One end of the water collection cylinder 200 is used for water inlet, and the other end is provided with a water outlet groove 201. The water outlet plate 300 is located on the side of the water outlet groove 201 away from the center of the water collection cylinder 200, and the pressure boosting plate 400 is located on the side of the water outlet plate 300 facing the center of the water collection cylinder 200. Specifically, the pressure plate 400 is arranged around the water outlet trough 201. The inner circumferential surface of the pressure plate 400 abuts against the water collection cylinder 200, and the outer circumferential surface of the pressure plate 400 abuts against the base shell 100, so as to form a pressure chamber 401 between the pressure plate 400 and the water outlet plate 300. Furthermore, multiple water outlet holes 3101 are distributed on the end face of the water outlet plate 300 to spray water outward. It should be noted that the water collecting cylinder 200 is located in the middle of the base shell 100, with a water inlet at one end and a water outlet trough 201 at the other end, serving to guide the water flow. Furthermore, the water outlet plate 300 is located on the side of the water outlet trough 201 away from the center of the water collecting cylinder 200, with multiple water outlet holes 3101 distributed on its end face for spraying water outwards. Additionally, the pressure boosting plate 400 is located inside the base shell 100 and on the side of the water outlet plate 300 facing the center of the water collecting cylinder 200, arranged around the water outlet trough 201. Its inner circumferential surface abuts against the water collecting cylinder 200, and its outer circumferential surface abuts against the base shell 100, thus forming a pressure boosting chamber 401 between the pressure boosting plate 400 and the water outlet plate 300. In application, when water flows in from the water collecting cylinder 200, it first enters this... The relatively enclosed and small pressurization chamber 401, according to fluid mechanics principles, allows water to flow within a smaller cross-sectional area, increasing flow velocity and pressure. This is analogous to squeezing a certain amount of water into a smaller space, naturally raising the water pressure. Consequently, water that might otherwise have insufficient pressure due to pipe resistance receives effective pressure replenishment. When this pressure is released from the multiple water outlets 3101 on the end face of the water outlet plate 300, it has higher pressure, allowing for a stronger and more concentrated spray. This effectively solves the problem of insufficient water pressure in traditional showerheads, significantly improving user comfort and providing a more impactful and effective cleaning experience. Simultaneously, the multiple dispersed water outlets 3101 ensure even water distribution, further enhancing the bathing experience.

[0029] Optionally, the pressure plate 400 is welded and fixed to the water collection cylinder 200 and the base shell 100 on both sides, respectively, to form a stable and durable connection structure. This effectively prevents the pressure plate 400 from shifting or loosening due to water flow impact, pressure changes, or other factors during use. Compared to other connection methods, such as bolted or snap-fit ​​connections, welding eliminates issues like thread wear and reduced snap-fit ​​elasticity, ensuring the accuracy and stability of the pressure plate 400's position. This keeps the pressure-boosting chamber 401 structure formed between the pressure plate 400, the water collection cylinder 200, and the base shell 100 stable at all times. Water can flow within the pressure-boosting chamber 401 according to the designed path, thereby continuously and efficiently achieving the pressure-boosting function. This provides a stable and strong water pressure to the sprinkler head, improving the overall reliability and durability of the sprinkler head. Optionally, the pressure plate 400, base shell 100, and water collection cylinder 200 are all made of metal, possessing high strength and hardness. They can withstand the significant pressure and impact generated when water flows at high speed within the pressure chamber 401, ensuring that the pressure plate 400, base shell 100, and water collection cylinder 200 will not easily deform or be damaged during long-term use. For example, if the pressure plate 400, base shell 100, and water collection cylinder 200 are all made of stainless steel, they have excellent corrosion resistance, resisting the erosion of various chemicals and minerals that may be present in the water, thus extending the service life of the sprinkler head. Furthermore, metal has good thermal conductivity, allowing for rapid temperature balancing under different water temperature environments. This prevents adverse effects on sprinkler head performance due to excessively high or low local temperatures, ensuring stable operation of the sprinkler head under various water quality and temperature conditions, providing users with a continuous and reliable pressurized water output effect. Similarly, the water outlet plate 300 is welded and fixed to the base shell 100. This welding firmly connects the water outlet plate 300 to the base shell 100, preventing displacement, shaking, or loosening during use. It ensures the accurate relative position of the water outlet hole 3101 and the pressurization chamber 401, allowing the water pressurized by the pressurization chamber 401 to accurately spray out through the water outlet hole 3101, achieving a uniform and stable water output. Furthermore, the welding fixation improves the sealing between the water outlet plate 300 and the base shell 100, preventing water leakage at the connection point. It ensures that all water is pressurized by the pressurization chamber 401 before being sprayed out through the water outlet hole 3101, further improving the nozzle's pressurization efficiency and water output performance, and extending the nozzle's service life.

[0030] In some embodiments of this utility model, the two sides of the pressure boosting plate 400 are respectively sealed to the water collecting cylinder 200 and the base shell 100, which can effectively prevent water leakage around the pressure boosting chamber 401 and ensure that all or most of the water entering the water collecting cylinder 200 can enter the pressure boosting chamber 401 for pressurization. Furthermore, the sealed connection ensures that the water flow can be concentrated within the pressure boosting chamber 401, fully utilizing the spatial structure of the pressure boosting chamber 401 to compress and accelerate the water flow, so that the water flow obtains sufficient pressure after passing through the pressure boosting chamber 401 and is ejected from the water outlet 3101, thereby significantly improving the pressure boosting efficiency and water pressure of the nozzle, providing users with a better water usage experience. For example, a sealing ring is provided between the inner side of the pressure boosting plate and the water collecting cylinder, and a sealing ring is provided between the outer side of the pressure boosting plate and the base shell (not shown in the figure). In some embodiments of this utility model, the inner periphery of the pressure plate 400 is welded and fixed to the water collection cylinder 200 by annular weld beads, and the outer periphery of the pressure plate 400 is welded and fixed to the base shell 100 by annular weld beads. On the one hand, it can achieve continuous and uniform sealing between the pressure plate 400, the water collection cylinder 200, and the base shell 100. Compared with spot welding or intermittent welding, the annular weld can avoid local weak points or poor sealing, ensuring that the boundary of the pressure chamber 401 is intact and well sealed. Under the impact of water flow, the annular weld can effectively resist stress and prevent cracking or deformation of the connection parts, thereby ensuring that the pressure chamber 401 is always in the best pressure working state, continuously providing a stable and efficient pressure effect for the nozzle, and improving the overall performance and reliability of the nozzle. On the other hand, the annular weld also provides a sealing effect on the inner and outer circumferences of the pressure plate 400 to a certain extent. While achieving the connection through welding and fixing, it also achieves the sealing between the inner side of the pressure plate 400 and the water collection cylinder 200, as well as the sealing between the outer side of the pressure plate 400 and the base shell 100.

[0031] During nozzle operation, the pressure plate 400 needs to withstand the strong pressure from the high-pressure water flow inside the pressure chamber 401, which can easily cause deformation. (Refer to...) Figure 2 In some embodiments of this utility model, the surface of the pressure booster plate 400 is provided with reinforcing ribs 410. These ribs not only disperse the pressure of the water flow on the pressure booster plate 400, allowing for more even stress distribution when under pressure, thus preventing localized stress concentration that could lead to deformation or damage, but also enhance the strength of the pressure booster plate 400. This ensures a tight contact between the pressure booster plate 400, the water collecting cylinder 200, and the base shell 100, maintaining the precise dimensions and shape of the pressure boosting chamber 401. This ensures that the water flow within the pressure boosting chamber 401 can be efficiently compressed and pressurized according to design requirements. Therefore, the reinforcing ribs 410 improve the deformation resistance of the pressure booster plate 400, thereby enhancing the pressurization effect of the nozzle and its long-term stability.

[0032] Optionally, in some embodiments of this utility model, such as Figure 1 As shown, the maximum width of the pressurizing chamber 401 in the thickness direction of the water outlet plate 300 is A, which satisfies A≤10mm. Strict control of the width of the pressurizing chamber 401 is a key design feature for achieving efficient pressurization. In application, the smaller width of the pressurizing chamber 401 significantly reduces the cross-sectional area of ​​the flow channel after the water enters the chamber. According to fluid mechanics principles, with a constant flow rate, the smaller the cross-sectional area of ​​the flow channel, the faster the water flow velocity and the greater the pressure. This design allows the water flow to be rapidly compressed within the pressurizing chamber 401, resulting in higher pressure and stronger impact when ejected through the water outlet 3101. Preferably, 4mm≤A≤7mm. By precisely controlling the maximum width of the pressurizing chamber 401, the nozzle can effectively increase the outlet water pressure without adding additional power equipment, providing users with a strong and concentrated water flow, meeting their demand for a high-quality water experience, and simultaneously optimizing the internal space utilization efficiency of the nozzle.

[0033] Refer to Figures 1 to 3 In some embodiments of this utility model, multiple nozzles 310 are distributed on the end face of the water outlet plate 300, and water outlet holes 3101 are disposed on the nozzles 310. It should be noted that the nozzles 310 can further guide and concentrate the water flow from the water outlet holes 3101, causing the water flow to be sprayed out in a more concentrated and impactful manner. Compared to ordinary water outlet holes 3101, nozzles 310 can accelerate and shape the water flow, enhancing its penetration and cleaning effect. Simultaneously, the distributed arrangement of multiple nozzles 310 allows the water flow to evenly cover a larger area, avoiding situations where the local water flow is too strong or too weak, providing users with a more comfortable and comprehensive bathing experience. The coordinated design of the nozzles 310 and water outlet holes 3101, combined with the pressurization function of the pressurization chamber 401, further optimizes the water output performance of the spray head, meeting users' needs for high-quality and diverse water flow effects.

[0034] A shower assembly according to an embodiment of the present invention includes a shower head according to an embodiment of the present invention. Integrating the optimized shower head into the shower assembly allows the entire shower system to fully utilize the pressurization advantage of the shower head, providing users with a more comfortable and convenient showering experience. In application, users can enjoy the powerful and uniform water flow provided by the shower head, enhancing the overall quality of the shower.

[0035] Other configurations and operations of the shower assembly according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
