[0003] However, in existing technologies, the water distribution of showerheads is not very uniform. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a shower head and fluid treatment equipment, which aims to at least partially solve the technical problem of poor water uniformity of the shower head.

[0005] The technical solution of this utility model is as follows:

[0006] A shower head, characterized in that it has a water inlet channel and a chamber communicating with the water inlet channel, and a plurality of water outlet holes communicating with the chamber. The shower head includes a water guide portion inclined relative to the axis of the outlet of the water inlet channel; wherein the water guide portion is located in the flow path of the fluid at the outlet of the water inlet channel, and / or, the water guide portion is located in the flow path of the fluid at the outlet of the water outlet holes.

[0007] In some embodiments, the water guide includes a first water guide surface located at the outlet of the water inlet channel, extending in the water outlet direction away from the central axis of the outlet of the water inlet channel.

[0008] In some implementations, the extension line of the first water guide surface intersects the axis of the water outlet at the inlet of the water outlet.

[0009] In some embodiments, the water guiding portion includes a protrusion disposed within the cavity; wherein the protrusion has an inclined second water guiding surface, the end of the second water guiding surface near the water outlet being lower than the end of the second water guiding surface near the water inlet channel.

[0010] In some embodiments, the protrusion has a through hole that communicates with the chamber and extends through the protrusion, and the through hole is coaxially arranged with the water inlet channel.

[0011] In some implementations, the second water guide surface extends to the edge of the water outlet.

[0012] In some embodiments, the shower head has a water guide located outside the chamber, and the water outlet hole passes through the water guide; wherein, the water guide includes a third water guide surface located at the water outlet end of the water guide, and the third water guide surface extends in the direction away from the central axis of the outlet of the water inlet channel along the water outlet direction.

[0013] In some implementations, the angle between the third water guiding surface and the water outlet direction is 10° to 80°.

[0014] In some embodiments, the water outlet includes a first section and a second section connected in the water outlet direction. The diameter of the first section is not smaller than the diameter of the second section. The diameter of the first section is 0.4 mm to 5 mm, and the diameter of the second section is 0.3 mm to 4 mm. The diameter of the first section decreases along the water outlet direction.

[0015] In some embodiments, the shower head has multiple water guides located outside the chamber, and the multiple water guides are arranged around the multiple water outlets; wherein, the water outlet end of the water guide has an inclined surface, which extends toward the central axis of the outlet of the water inlet channel along the water outlet direction.

[0016] In some embodiments, the ramp has at least one corner.

[0017] In some embodiments, the shower head includes a first cover and a second cover connected to the first cover, the first cover and the second cover together forming the chamber, the first cover having the water inlet channel and the second cover having the water outlet hole; wherein, a first sealing element is provided between the first cover and the second cover.

[0018] Based on the same inventive concept, this utility model also provides a fluid processing device, including a body and the shower head; the body is connected to the shower head; wherein a second sealing element is provided between the shower head and the body.

[0019] In some embodiments, the fluid handling device is a coffee machine, which further includes a coffee filter basket located below the showerhead along the water outlet direction.

[0020] According to one or more embodiments of this application, a shower head is provided with a water inlet channel and a chamber communicating with the water inlet channel. Water can flow into the chamber through the water inlet channel. The shower head has multiple water outlet holes communicating with the chamber, and water in the chamber can be discharged through the water outlet holes. Since the shower head includes a water guide portion that is inclined relative to the axis of the outlet of the water inlet channel, and the water guide portion is located in the flow path of the fluid at the outlet of the water inlet channel, and / or, the water guide portion is located in the flow path of the water outlet holes, when water flows from the water inlet channel into the chamber, the water guide portion can guide the water flow so that the water flows away from the central axis of the water inlet channel. The water section can guide the water flow to multiple outlet holes, ensuring that the water flows towards the outlet holes and exits the chamber through multiple outlet holes. This ensures that the water flow can fall evenly, improving the uniformity of the shower head's water output. When the water flows out of the outlet holes, the water guide section can guide the water flow to flow away from the central axis of the water inlet channel, allowing the water flow to be more widely dispersed when leaving the shower head. By expanding the spray range of the shower head, it can cover a larger area in a shorter time, thereby improving spray efficiency and ensuring that the powder can be evenly sprayed, improving the uniformity of the shower head's water output and ensuring that the powder is evenly extracted.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] It should be noted that all directional indications in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0045] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0046] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0047] During the operation of fluid processing equipment, heated hot water is usually mixed with powder by direct injection. Due to the concentrated injection of hot water, the mixing speed of powder and hot water is very slow and it is easy to clump. When the powder is coffee powder, the brewing time is long and the brewed coffee has uneven solubility and poor taste.

[0048] In related technologies, fluid handling equipment also uses a shower head structure at the hot water outlet to make the water flow more uniform. However, since the shower head includes multiple spray nozzles, the water flow is still difficult to cover the surrounding spray nozzles due to its own weight. As a result, the water flow will be concentrated in a few spray nozzles in the center of the shower head, leading to poor water uniformity.

[0049] Based on the above-mentioned technical problems, this application provides a shower head and fluid treatment device, which aims to solve the technical problem of poor water uniformity of the shower head to at least a certain extent.

[0050] The design concept of this application is to improve the uniformity of water output by setting up a water guide section to direct the water flow away from the central axis of the water inlet channel.

[0051] Based on the above design concept, in the first aspect of this application, an embodiment of this application provides a shower head 1000. Figure 1 These are schematic diagrams of the shower head structure in some embodiments; Figure 2 for Figure 1 A cross-sectional view of the central shower head. (Combined with...) Figure 1 and Figure 2 The shower head 1000 has a water inlet channel 10 and a chamber 20 communicating with the water inlet channel 10. The shower head 1000 also has multiple water outlet holes 40 communicating with the chamber 20. The shower head 1000 includes a water guiding section 130. The water guiding section 130 is inclined relative to the axis of the outlet of the water inlet channel 10. The water guiding section 130 is located in the flow path of the fluid at the outlet of the water inlet channel 10, and / or, the water guiding section 130 is located in the flow path of the water outlet holes 40.

[0052] The shower head 1000 provided in this application has a water inlet channel 10 and a chamber 20 communicating with the water inlet channel 10. Water can flow into the chamber 20 through the water inlet channel 10. The shower head 1000 has multiple water outlet holes 40 communicating with the chamber 20. Water in the chamber 20 can be discharged through the water outlet holes 40. Since the shower head 1000 includes a water guide part 130 that is inclined relative to the axis of the outlet of the water inlet channel 10, and the water guide part 130 is located in the flow path of the fluid at the outlet of the water inlet channel 10, and / or the water guide part 130 is located in the flow path of the water outlet holes 40, when water flows from the water inlet channel 10 into the chamber, the water guide part 130 can guide the water flow so that the water flows away from the central axis of the water inlet channel 10. The water guide section 130 directs the water flow to multiple water outlets 40, allowing the water to flow towards the outlets 40 and exit the chamber through them. This ensures the water falls evenly, improving the uniformity of the water output from the shower head 1000. When the water is discharged from the outlets 40, the water guide section 130 guides the water flow away from the central axis of the inlet channel 10, allowing the water to spread more widely when leaving the shower head 1000. By expanding the spray range of the shower head 1000, it can cover a larger area in a shorter time, thereby improving spray efficiency and ensuring that the powder is evenly sprayed, thus improving the uniformity of the water output from the shower head 1000 and ensuring that the powder is evenly extracted.

[0053] Furthermore, since water can flow out of chamber 20 through multiple water outlets 40, the water coverage of the shower head 1000 is high, and the water flow can evenly enter the powder. This allows the powder to be subjected to a more uniform water flow impact during the extraction process, avoiding uneven extraction caused by excessive or insufficient moisture in certain areas. This uniform wetting condition helps the active ingredients in the powder to dissolve or be released more fully into the water, thereby improving the quality and consistency of the extracted product.

[0054] In some embodiments, to ensure the uniformity of water output from the shower head 1000, the water guiding section 130 includes a first water guiding surface 11 located at the outlet of the water inlet channel 10. After water enters the water inlet channel 10, the water flows along the first water guiding surface 11. Since the first water guiding surface 11 extends away from the central axis of the water inlet channel 10 along the water outlet direction, the first water guiding surface 11 guides the water flow, causing the water to flow away from the central axis of the water inlet channel 10. The shower head 1000 has a through hole 30 coaxial with the water inlet channel 10 and multiple water outlet holes 40 surrounding the through hole 30. Both the through hole 30 and the water outlet holes 40 are connected to the chamber 20. Therefore, the first water guiding surface 11 can guide the water flow to the multiple water outlet holes 40 surrounding the through hole 30, so that the water flow flows in the direction of the water outlet holes 40. The water flow can flow out of the chamber 20 through the multiple water outlet holes 40, ensuring that the water flow can fall evenly and improving the uniformity of the water output of the shower head 1000.

[0055] As the water flows along the first guide surface 11, under the influence of gravity and the inertia of the water flow, after leaving the first guide surface 11, the water will continue to flow along the extension line of the first guide surface 11. (Combined with...) Figure 4 In some embodiments, in order to further ensure that the first water guiding surface 11 can guide the water flow to the water outlet 40, the extension line of the first water guiding surface 11 intersects the axis of the water outlet 40 at the inlet of the water outlet 40, so that the water flow can flow directly into the inlet of the water outlet 40, thereby reducing the possibility of the water flow reaching the area outside the water outlet. The water flow can fully flow into the water outlet 40, ensuring that the water flow can fall evenly and improving the uniformity of the water output of the shower head 1000.

[0056] Combination Figure 2 In some embodiments, to further ensure that water can be discharged through the outlet hole 40, the water guiding part 130 includes a protrusion 50 located in the chamber 20. The protrusion 50 has an inclined second water guiding surface 51, and the end of the second water guiding surface 51 near the outlet hole 40 is lower than the end of the second water guiding surface 51 near the water inlet channel 10.

[0057] Specifically, when water flows into the chamber 20 through the inlet channel 10, due to the impact force of the water flow, some of the water may leave the first guide surface 11 under the action of the impact force, causing the water to fall directly into the chamber 20. After leaving the first guide surface 11, the water will fall onto the protrusion 50, and the water flow will be guided by the second guide surface 51 inclined on the protrusion 50. Since the end of the second guide surface 51 near the outlet hole 40 is lower than the end of the second guide surface 51 near the inlet channel 10, under the action of gravity, the second guide surface 51 will guide the water flow to the outlet hole 40. The water flow can flow out of the chamber 20 through multiple outlet holes 40, ensuring that the water flow can fall evenly and improving the uniformity of the water output of the shower head 1000.

[0058] In some embodiments, in order to further ensure the water coverage of the shower head 1000, the protrusion 50 is provided with a through hole 30 that communicates with the chamber 20 and extends through the protrusion 50. The through hole 30 is coaxially arranged with the water inlet channel 10. When a certain amount of water flow accumulates in the chamber 20, that is, when the water flow overflows the protrusion 50, the water flow can be discharged through the through hole 30, which further increases the water coverage of the shower head 1000, so that the water flow can enter the powder evenly and achieve uniform extraction of the powder.

[0059] It should be noted that the water flow in the inlet channel 10 contains gas. During the process of water flowing into the chamber 20, the gas separates from the water flow. In related technologies, when water flows out through the outlet hole, due to the surface tension of the water, a water film forms at the outlet hole. When gas reaches the water film, it forms bubbles. As gas continuously enters the water film, the bubbles continuously enlarge until they explode, causing water to splash at the outlet hole, resulting in uneven water flow. In this embodiment, the first water guiding surface 11 can guide the water flow to multiple outlet holes 40 surrounding the through hole 30. That is, the through hole 30, which is coaxially arranged with the inlet channel 10, will not have water flow holes. At this time, the through hole 30 can act as an air vent, allowing the gas separated from the water flow to be discharged through the through hole 30, thereby reducing the possibility of bubbles forming at the multiple outlet holes 40, further ensuring that the water flow can fall evenly, and improving the uniformity of the shower head 1000's water output. Moreover, when a certain amount of water accumulates in the chamber 20, the water can be discharged through the through hole 30, which further increases the water coverage of the shower head 1000, allowing the water to enter the powder evenly and achieving uniform extraction of the powder.

[0060] In some embodiments, in order to further ensure the uniformity of water output from the shower head 1000, multiple water outlet holes 40 are evenly spaced at equal angles. That is, multiple water outlet holes 40 are evenly distributed in an array with the through hole 30 as the center point. When water flows out through multiple water outlet holes 40, the powder can be evenly sprayed, ensuring that the powder is evenly extracted.

[0061] In some embodiments, in order to ensure that the water flowing away from the first water guide surface 11 can flow fully to the outlet hole 40, the second water guide surface 51 extends to the edge of the outlet hole 40, providing a more direct and shorter path for the water to flow to the outlet hole 40. When the water leaves the first water guide surface 11, it can flow directly to the outlet hole 40, reducing the resistance and time of the water flow during the flow process, ensuring smooth water flow. At the same time, it guides the water flow to be concentrated around the outlet hole 40, so that the water flow is preferentially discharged through the outlet hole 40, thereby ensuring that the water output from the outlet hole 40 is uniform and stable.

[0062] Figure 4 for Figure 1 A bottom view of the central shower head. (Combined with...) Figure 2 and Figure 4 In some embodiments, to ensure the spray range of the shower head 1000, the shower head 1000 has a water guide 60 located outside the chamber 20, and the water outlet 40 passes through the water guide 60. The water guide portion 130 includes a third water guide surface 61 located at the water outlet end of the water guide 60, and along the water outlet direction, the third water guide surface 61 extends in a direction away from the central axis of the outlet of the water inlet channel 10.

[0063] Specifically, when water flows out of chamber 20 through outlet 50, it flows to the outlet end of guide 60 and encounters third guide surface 61. Guided by the third guide surface 61, the water flows away from the central axis of the outlet of inlet channel 10, allowing it to disperse more widely upon leaving the showerhead, rather than being concentrated near the central axis of outlet 40. This significantly expands the spray range of showerhead 1000. Furthermore, by expanding the spray range, showerhead 1000 can cover a larger area in a shorter time, thereby improving spray efficiency and ensuring that the powder is evenly sprayed and extracted.

[0064] Combination Figure 2 Furthermore, to ensure the spray range of the shower head 1000, the angle α between the third water guide surface 61 and the water outlet direction is 10° to 80°. For example, the angle α between the third water guide surface 61 and the water outlet direction is 58°.

[0065] Combination Figure 2 In some embodiments, to create a more uniform and wider spray range, the water outlet 40 includes a first section 41 and a second section 42 connected along the water outlet direction. The diameter of the first section 41 is not smaller than the diameter of the second section 42. The diameter of the first section 41 is 0.4 mm to 5 mm, and the diameter of the second section 42 is 0.3 mm to 4 mm. For example, the diameter of the second section 42 can be 1.7 mm. The diameter of the first section 41 decreases along the water outlet direction.

[0066] Specifically, since the orifice diameter of the first orifice section 41 is not smaller than that of the second orifice section 42, the water flow can maintain a large flow area within the first orifice section 41 before entering the second orifice section 42, reducing water flow resistance. When the water flow enters the second orifice section 42, due to the reduction in orifice diameter, the water flow is forced to accelerate and concentrate, thereby enhancing the jet pressure and velocity of the water flow. This makes the water flow jetted from the second orifice section 42 more powerful, increases the spray range of the water flow, and ensures that the powder can be evenly sprayed, guaranteeing uniform extraction of the powder. At the same time, since the orifice diameter of the first orifice section 41 decreases along the water outlet direction, that is, the inlet area of ​​the first orifice section 41 is larger, it facilitates the water flow entering the first orifice section 41. Moreover, the gradual design of the first orifice section 41 helps the water flow to transition more smoothly when flowing out of the outlet hole 40, avoiding water flow turbulence caused by abrupt changes in orifice diameter. This makes the water flow more stable during the jetting process, helping to form a more uniform and wider spray range, further ensuring that the powder can be evenly sprayed, and thus ensuring uniform extraction of the powder.

[0067] Combination Figure 2 In some embodiments, the first orifice 41 may be conical to guide water flow to the second orifice 42. The included angle β of the conical surface opening of the first orifice 41 may be 0° to 180°. For example, the included angle β of the conical surface opening of the first orifice 41 may be 75°.

[0068] In related technologies, hot water is typically used to extract powder. When the hot water flows to the powder, it generates water vapor, which condenses outside the chamber 20. Furthermore, during the spraying process at the water outlet 40, some water mixes into the condensate, increasing the amount of condensate outside the chamber 20. The high surface tension of the condensate causes it to condense into larger droplets before falling. However, the droplet placement is unpredictable, and the water volume is uncontrollable, resulting in uneven powder distribution and affecting extraction. In some embodiments, to further achieve uniform powder extraction, the shower head 1000 has multiple water guides 70 located outside the chamber 20, arranged around the multiple water outlets 40. Each water guide 70 has a bevel 71 at its outlet end, extending in the direction of water flow towards the central axis of the water inlet channel 10.

[0069] Specifically, when water vapor condenses outside chamber 20, condensate also forms on the water guide 70. Under the influence of gravity, the condensate on the water guide 70 drips down. During the dripping process, the condensate on the water guide 70 pulls the condensate near the water guide 70, guiding the condensate outside chamber 20 onto the water guide 70. This prevents the condensate from irregularly accumulating and forming large water droplets outside chamber 20. The condensate is dispersed into fine water streams or droplets, which drip down below the water guide 70. This reduces the uncertainty of droplet aggregation and tension, and makes the droplet position and volume more controllable, ensuring that the condensate dripping position is definite and the dripping volume is small. When these fine water droplets or streams come into contact with the powder again, they can more evenly wet the powder, improving extraction efficiency.

[0070] Furthermore, as the condensate on the guide 70 flows to the inclined plane 71, it flows along the plane, forming a sharp point at its lowest point. This sharp point punctures the water film, breaking it into smaller droplets. These smaller droplets flow more easily along the inclined plane 71, reducing flow resistance caused by an excessively thick water film. Simultaneously, the smaller droplets are more easily dispersed by gravity and surface tension, preventing excessive localized water accumulation. This uniform dispersion ensures the condensate drips evenly, allowing the powder to experience a more uniform water flow impact during extraction, avoiding uneven extraction caused by excessive or insufficient localized water. This uniform wetting condition helps the active ingredients in the powder dissolve or release more fully into the water, thereby improving the quality and consistency of the extracted product.

[0071] Meanwhile, since the inclined surface 71 extends towards the central axis of the outlet of the water inlet channel 10 along the water outlet direction, when the inclined surface 71 guides the water flow, it can make the water flow towards the central axis of the outlet of the water inlet channel 10, preventing condensed water from dripping outside the coffee filter basket. This not only reduces the uncertainty of water droplet accumulation and tension-induced droplet falling, but also makes the droplet falling position and water volume more controllable.

[0072] Combination Figure 2In some embodiments, to allow the condensate guided by the inclined surface 71 to form finer water streams or droplets, the inclined surface 71 has at least one corner 72, each corner forming a sharp point. When the condensate passes through the sharp point, the sharp point can pierce the water film of the condensate. Because the water film is pierced into finer water streams or droplets, these fine water streams or droplets can flow more easily along the inclined surface 71, reducing the flow resistance caused by an excessively thick water film. At the same time, the fine water streams or droplets are more easily dispersed by gravity and surface tension during the flow, avoiding excessive local accumulation of water. The guide 70 has a blind hole 73, the edge of which forms a corner 72.

[0073] Figure 5 for Figure 1 A schematic diagram of the structure of the first cover of the central shower head; Figure 6 for Figure 1 A schematic diagram of the structure of the second cover of the central shower head. (Combined with...) Figure 5 and Figure 6 In some embodiments, to form the chamber 20, the shower head 1000 includes a first cover 80 and a second cover 90 connected to the first cover 80. The first cover 80 and the second cover 90 together form the chamber 20. The first cover 80 has a water inlet channel 10, and the second cover 90 has a through hole 30 and a water outlet hole 40. Water can enter the chamber 20 through the water inlet channel 10 of the first cover 80 and be discharged through the water outlet hole 40 of the second cover 90. A first sealing element 100 is provided between the first cover 80 and the second cover 90, which improves the sealing performance of the chamber 20. The first sealing element 100 effectively prevents water from leaking from the gap between the first cover 80 and the second cover 90, ensuring smooth water flow and efficient utilization. At the same time, the improved sealing also reduces safety hazards and energy waste caused by water leakage.

[0074] Figure 3 for Figure 1 A top view of the central shower head. (Combined with...) Figure 2 and Figure 3 In some embodiments, in order to supply water to the water inlet channel 10, the shower head 1000 further includes a water inlet pipe 120. The water inlet pipe 120 is connected to the water inlet channel 10 at an angle, and can deliver external water flow into the water inlet channel 10.

[0075] Specifically, since the inlet pipe 120 is connected to the inlet channel 10 at an angle, the water delivered from the inlet pipe 120 to the inlet channel 10 will impact the wall of the inlet channel 10. The wall of the inlet channel 10 buffers the water flow, allowing it to flow along the wall of the inlet channel 10. This allows the water flow to be guided by the first guide surface 11, preventing the water from being discharged directly through the through hole 30. The angle between the inlet pipe 120 and the inlet channel 10 can be a right angle, an acute angle, or an obtuse angle.

[0076] Based on the same inventive concept, this application also proposes a fluid processing device that uses the aforementioned shower head. The specific structure of the shower head is as described in the above embodiments. Since it adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0077] In some embodiments, the fluid processing equipment can be a coffee machine, soy milk maker, milk powder machine, milk tea machine, or other equipment that requires the addition of water to the powder; this application embodiment does not limit this. Water flows into the container of the fluid processing equipment through the shower head 1000, and then the powder is extracted by the fluid processing equipment.

[0078] In some embodiments, to facilitate the installation of the shower head 1000, the fluid handling device includes a body connected to the shower head 1000. The body serves as an installation base, providing support for the installation of the shower head 1000 and ensuring its stability. A second seal 110 is provided between the shower head 1000 and the body. The second seal 110 ensures a good seal at the connection between the shower head 1000 and the body, preventing fluid (such as steam, water, or other liquids) from leaking inside the body, thereby maintaining the normal operation of the body.

[0079] In some embodiments, for coffee extraction, the fluid handling device is a coffee machine, which also includes a coffee filter basket positioned below the shower head 1000 along the water outlet direction. Coffee grounds are arranged within the coffee filter basket. The shower head 1000, as the water outlet component of the coffee machine, can evenly spray hot water onto the coffee grounds. When the coffee filter basket is positioned below the shower head 1000, the hot water can directly and evenly cover the coffee grounds, ensuring that each coffee particle is fully extracted, achieving a more uniform extraction effect and avoiding over-extraction or under-extraction of some coffee grounds, thereby improving the taste and quality of the coffee. Furthermore, because the hot water is sprayed directly onto the coffee grounds in the coffee filter basket, heat loss during transmission is reduced, making the extraction process more efficient. Efficient extraction means that more coffee can be produced in a shorter time, improving the production efficiency of the coffee machine and user satisfaction.
