Description

Technical Field

[0001] This invention relates to the field of sanitary ware technology, and in particular to slow-release modules and water outlet devices. Background Technology

[0002] As people's living standards improve, users have increasingly higher requirements for water quality. A slow-release module is a device that stores slow-release materials. After being placed in a water storage device such as a water pipe or tank, the slow-release materials stored in the module are slowly released into the storage device and mix with the water, thereby achieving functions such as descaling and dechlorination. Because the release of the slow-release materials is a slow and automatic process, the effectiveness of the slow-release module will change over time. Summary of the Invention

[0003] Therefore, it is necessary to address the issue of efficacy changes over time by providing a slow-release module and a water outlet device. As the storage capacity of the slow-release material decreases over time, the extruder will gather the slow-release material towards the slow-release wall, ensuring that the effective area of ​​the slow-release material released into the slow-release chamber at any given time is the area of ​​the slow-release wall. Moreover, the volume of the slow-release chamber remains unchanged, and the amount of water it can hold remains unchanged. As a result, the release rate of the slow-release material into the slow-release chamber is more consistent, the concentration of the functional solution remains unchanged, and the efficacy of the slow-release module is more consistent before and after.

[0004] A sustained-release module, comprising:

[0005] A sustained-release chamber, wherein the chamber wall is provided with a sustained-release hole;

[0006] A sealed cavity is used to store slow-release material. The sealed cavity and the slow-release cavity share a common cavity wall, and this common cavity wall is a slow-release wall. The other cavity walls of the sealed cavity are sealed walls. The slow-release material in the sealed cavity can be released into the slow-release cavity through the slow-release wall.

[0007] An extruder configured to compress the sealing wall as the amount of slow-release material stored in the sealing cavity decreases, thereby converging the slow-release material in the sealing cavity toward the slow-release wall, while the area of ​​the slow-release wall remains constant during the converging process.

[0008] In one embodiment, the portion of the sealing wall opposite to the sustained-release wall is a compression-receiving portion, the extruder acts on the compression-receiving portion, and the direction of the extrusion force applied by the extruder to the compression-receiving portion is from the compression-receiving portion toward the sustained-release wall.

[0009] In one embodiment, the sustained-release module includes a temporary storage housing that surrounds the sustained-release cavity, and the sustained-release orifice is formed on the temporary storage housing;

[0010] The sustained-release module also includes a sealed container, and the temporary storage shell is slidably inserted into the sealed container. The sealed container and the temporary storage shell define the sealed cavity. The bottom wall of the sealed container is the compression force-bearing part, and the part of the temporary storage shell opposite to the compression force-bearing part is the sustained-release wall.

[0011] In one embodiment, the temporary storage housing is sealed to the side wall of the sealed barrel;

[0012] And / or, the slow-release orifice is located on the temporary storage housing, directly opposite the slow-release wall.

[0013] In one embodiment, the sustained-release module further includes a waterproof isolation cylinder, the connection between the temporary storage shell and the sealing barrel is located inside the waterproof isolation cylinder, and both the temporary storage shell and the sealing barrel are sealed to the waterproof isolation cylinder. At least one of the temporary storage shell and the sealing barrel is slidable relative to the waterproof isolation cylinder, and the direction in which it is slidable relative to the waterproof isolation cylinder is consistent with the slidable direction between the temporary storage shell and the sealing barrel. The sustained-release hole is located outside the waterproof isolation cylinder.

[0014] In one embodiment, the temporary storage housing is divided into an insertion portion and an extension portion in a direction slidable relative to the sealing barrel. The insertion portion can be inserted into the sealing barrel. The length direction of the waterproof isolation cylinder is consistent with the direction in which the temporary storage housing can slide relative to the sealing barrel. One end of the waterproof isolation cylinder is connected to the extension portion, and the extension portion seals the opening at that end of the waterproof isolation cylinder. The sealing barrel is located inside the waterproof isolation cylinder and is slidable relative to the waterproof isolation cylinder. A sealing ring is provided between the sealing barrel and the waterproof isolation cylinder. The slow-release hole is formed on the extension portion.

[0015] In one embodiment, the temporary storage shell and the waterproof isolation cylinder are integrally formed and connected. The space enclosed by the outward portion is a columnar structure, and the space enclosed by the insertion portion is a columnar structure. The outer diameter of the outward portion is larger than the outer diameter of the insertion portion. The outer diameter of the waterproof isolation cylinder is the same as the outer diameter of the outward portion, and the outer diameter of the sealing barrel is located between the outer diameter of the insertion portion and the outer diameter of the waterproof isolation cylinder.

[0016] In one embodiment, the waterproof insulating cylinder has an end wall located on the side of the extrusion force-bearing portion away from the slow-release wall, and the extrusion member acts between the end wall and the extrusion force-bearing portion.

[0017] In one embodiment, the extrusion member is an elastic member;

[0018] And / or, the slow-release wall is provided with a plurality of spaced-apart small holes, through which the slow-release material in the sealed cavity can be released into the slow-release cavity.

[0019] A water outlet device includes a water outlet channel and a slow-release module as described in any of the preceding claims, wherein the slow-release module is placed in the water outlet channel.

[0020] The above solution provides a slow-release module and a water dispensing device. In use, the slow-release material is placed in a sealed cavity, and the slow-release module is placed in water. When the slow-release module is initially placed in water, water enters the slow-release cavity through the slow-release holes, and the slow-release material is released into the water within the slow-release cavity via the slow-release wall, thus forming a functional solution within the cavity. When the user uses the water dispensing device, the functional solution in the slow-release cavity is discharged from the slow-release holes and mixed with the water, then supplied to the user. After use, the water dispensing device stops dispensing water, but water continues to fill the slow-release cavity, and the slow-release material continues to be released into the cavity from the slow-release wall. With the passage of time and repeated use, the slow-release material is gradually consumed. As the stored amount of slow-release material decreases, the extruder presses against the sealed wall, thereby converging the stored slow-release material towards the wall, ensuring that the effective area of ​​the slow-release material released into the slow-release cavity at any given time is the area of ​​the slow-release wall. Once user habits are formed, the interval between two uses generally does not differ significantly. Since the volume of the slow-release chamber remains constant, the volume of water within it also remains constant, resulting in a relatively consistent rate of release of the slow-release material. With a consistent release rate and duration, the amount of slow-release material released remains constant, consequently maintaining the concentration and volume of the functional solution. Therefore, the effectiveness of the slow-release module remains relatively consistent over time. Attached Figure Description

[0028] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] In some embodiments of this application, a sustained-release module 10 is provided, such as... Figures 1 to 3 As shown, the slow-release module 10 can be applied to the water outlet device 20. For example, in some embodiments, the water outlet device 20 includes a water outlet channel 21 and a slow-release module 10, with the slow-release module 10 placed in the water outlet channel 21. The slow-release module 10 can store a slow-release material 15, which is released and mixed with water to form a functional solution 16. The functional solution 16 can enter the water outlet channel 21 through the slow-release hole 112 of the slow-release module 10, and can achieve corresponding effects depending on the performance of the functional solution 16.

[0030] The specific slow-release material 15 can be in solid or paste form, and can be one or more of the following: scale inhibitors, chlorine removers, and skin-beautifying materials, etc.

[0031] Specifically, such as Figures 1 to 3 As shown, the sustained-release module 10 includes a sustained-release chamber 111, a sealing chamber 121, and a compression member 14.

[0032] Continue to refer to Figures 1 to 3 The wall of the slow-release cavity 111 is provided with a slow-release hole 112.

[0033] The sealed cavity 121 is used to store the slow-release material 15. The sealed cavity 121 and the slow-release cavity 111 share a common cavity wall, which is the slow-release wall 113. The other cavity walls of the sealed cavity 121 are the sealing walls 122. The slow-release material 15 in the sealed cavity 121 can be released into the slow-release cavity 111 through the slow-release wall 113. For example, in some cases, the slow-release wall 113 has multiple spaced-apart holes, through which the slow-release material 15 in the sealed cavity 121 can be released into the slow-release cavity 111. When the slow-release module 10 is placed in an aqueous environment, water first enters the slow-release cavity 111 through the slow-release hole 112, and the slow-release material 15 in the sealed cavity 121 is released into the slow-release cavity 111 and mixes with the water to form a functional solution 16.

[0034] The extruder 14 is configured to extrude the sealing wall 122 as the amount of slow-release material 15 stored in the sealing cavity 121 decreases, so as to gather the slow-release material 15 in the sealing cavity 121 toward the slow-release wall 113, and the area of ​​the slow-release wall 113 remains unchanged during the gathering process.

[0035] In use, the slow-release material 15 can be placed in the sealed cavity 121, and the slow-release module 10 can be placed in water. For example... Figure 1 As shown, when the slow-release module 10 is initially placed in water, water enters the slow-release chamber 111 through the slow-release hole 112. The slow-release material 15 is released into the slow-release chamber 111 through the slow-release wall 113 and mixes with the water, thereby forming a functional solution 16 in the slow-release chamber 111. When the user uses the water outlet device 20, as... Figure 2 As shown, with the flow of water, a negative pressure zone is formed at the location of the slow-release orifice 112. The functional solution 16 in the slow-release chamber 111 will be discharged from the slow-release orifice 112 and mixed with the water, and then provided to the user. When the water usage is finished, the water outlet 20 stops discharging water, and water will continue to fill the slow-release chamber 111, and the slow-release material 15 will continue to be released from the slow-release wall 113 into the slow-release chamber 111. Figure 2 and Figure 3As shown, with the passage of time and frequency of use, the slow-release material 15 is gradually consumed. As the storage amount of slow-release material 15 decreases, the extruder 14 compresses the sealing wall 122, thereby converging the stored slow-release material 15 towards the slow-release wall 113, ensuring that the effective area of ​​the slow-release material 15 released into the slow-release cavity 111 at any given time is the area of ​​the slow-release wall 113. Furthermore, the position of the slow-release wall 113 does not change, and the volume of the slow-release cavity 111 remains constant. Once user habits are formed, the interval between two uses generally does not differ significantly. Since the volume of the slow-release cavity 111 remains constant, the volume of water in the slow-release cavity 111 remains constant, and the release rate of the slow-release material 15 into the slow-release cavity 111 is relatively consistent. With a consistent release rate and duration, the release amount of the slow-release material 15 remains constant, thus keeping the concentration and volume of the functional solution 16 constant. Therefore, each time the user uses the water outlet device 20, the effectiveness of the slow-release module 10 remains relatively consistent, even as the usage time increases.

[0036] Specifically, the extruder 14 can squeeze the sealing wall 122 from the side of the sealing cavity 121, reducing the volume of the sealing cavity 121 and drawing the slow-release material 15 towards the slow-release wall 113. The side of the sealing cavity 121 furthest from the slow-release wall 113 is defined as the lower part of the sealing cavity 121, the side containing the slow-release cavity 111 is defined as the upper part of the sealing cavity 121, and other positions are defined as the sides of the sealing cavity 121. It should be noted that when squeezing the sealing wall 122 from the side, the squeezing position must ensure that it does not affect the contact area between the slow-release material 15 and the slow-release wall 113. For example, if the extruder 14 acts on the side of the sealing cavity 121 and away from the slow-release wall 113, while providing a lateral force to the sealing cavity 121, this point of force is also located away from the slow-release wall 113, so the slow-release material 15 can still converge towards the slow-release wall 113.

[0037] Of course, such as Figures 1 to 3 As shown, the extrusion member 14 can also provide force to the sealing wall 122 from the side of the sealing cavity 121 away from the release wall 113. In such cases... Figures 1 to 3 From the perspective shown, the extruder 14 can provide extrusion force to the sealing wall 122 from below the sealing cavity 121.

[0038] Specifically in some embodiments, such as Figure 1 and Figure 2As shown, the portion of the sealing wall 122 opposite to the slow-release wall 113 is the compression force-bearing portion 123. The extruder 14 acts on the compression force-bearing portion 123, and the direction of the extrusion force applied by the extruder 14 to the compression force-bearing portion 123 is from the compression force-bearing portion 123 towards the slow-release wall 113. The extruder 14 provides force to the sealing wall 122 through the compression force-bearing portion 123, causing the slow-release material 15 in the sealing cavity 121 to move closer to the slow-release wall 113.

[0039] like Figures 1 to 3 As shown, the extruder 14 provides an upward force to the sealing wall 122. The part of the cavity wall shared by the release cavity 111 and the sealing cavity 121 is always the top surface of the sealing cavity 121. The area of ​​the release wall 113 remains unchanged, so the effectiveness of the release module 10 can be ensured to be consistent.

[0040] The cavity wall of the sealed cavity 121 can be made of a deformable elastic material, such as an accordion cover or a rubber sleeve.

[0041] The cavity wall of the sealed cavity 121 can also be made of a rigid material with a fixed shape. For example, in some embodiments, such as Figures 1 to 3 As shown, the sustained-release module 10 includes a temporary storage housing 11, which forms the sustained-release cavity 111, and the sustained-release hole 112 is formed on the temporary storage housing 11.

[0042] The sustained-release module 10 also includes a sealed container 12, and the temporary storage housing 11 is slidably inserted into the sealed container 12. The sealed container 12 and the temporary storage housing 11 define the sealed cavity 121. The side walls and bottom walls of the sealed container 12 are both sealing walls 122. The bottom wall of the sealed container 12 is the compression force-bearing part 123. The part of the temporary storage housing 11 opposite to the compression force-bearing part 123 is the sustained-release wall 113.

[0043] At this time, both the temporary storage shell 11 and the sealed container 12 are fixed-shape structures that can slide together. When the amount of slow-release material 15 stored in the sealed cavity 121 decreases, the extruder 14 applies a compressive force to the sealed container 12, causing relative sliding between the sealed container 12 and the temporary storage shell 11, thereby changing the size of the sealed cavity 121 and ensuring that the slow-release material 15 adheres consistently to the slow-release wall 113. Meanwhile, the volume of the slow-release cavity 111 remains constant, and the only pathway for the slow-release material 15 to be released into the slow-release cavity 111 is through the slow-release wall 113, whose area remains unchanged.

[0044] To further prevent leakage of the slow-release material 15 in the sealed cavity 121, the temporary storage shell 11 and the side wall of the sealed container 12 can be sealed together. In other words, although the temporary storage shell 11 and the sealed container 12 can slide relative to each other, they are still in a sealed state.

[0045] Furthermore, in some embodiments, such as Figures 1 to 3 As shown, the slow-release module 10 also includes a waterproof isolation cylinder 13. The connection between the temporary storage shell 11 and the sealing barrel 12 is located inside the waterproof isolation cylinder 13, and both the temporary storage shell 11 and the sealing barrel 12 are sealed to the waterproof isolation cylinder 13. At least one of the temporary storage shell 11 and the sealing barrel 12 is slidable relative to the waterproof isolation cylinder 13, and the direction of its sliding relative to the waterproof isolation cylinder 13 is consistent with the sliding direction between the temporary storage shell 11 and the sealing barrel 12. In other words, the connection between the temporary storage shell 11 and the sealing barrel 12 is protected inside by the waterproof isolation cylinder 13, further reducing the possibility of water entering the sealing cavity 121 from this point. Of course, the presence of the waterproof isolation cylinder 13 does not hinder the relative sliding between the sealing barrel 12 and the temporary storage shell 11. When the temporary storage shell 11 and the sealing barrel 12 slide relative to each other, the waterproof isolation cylinder 13 slides relative to at least one of them.

[0046] The slow-release hole 112 is located outside the waterproof isolation cylinder 13, and the functional solution 16 in the slow-release cavity 111 can flow out of the slow-release module 10 through the slow-release hole 112 without being blocked by the waterproof isolation cylinder 13.

[0047] Specifically in one embodiment, such as Figure 2 and Figure 3 As shown, the slow-release hole 112 is located on the temporary storage housing 11, directly opposite the slow-release wall 113.

[0048] More specifically, in some embodiments, such as Figure 1 and Figure 2 As shown, the temporary storage housing 11 is divided into an insertion portion 114 and an extension portion 115 in a direction slidable relative to the sealing barrel 12. The insertion portion 114 can be inserted into the sealing barrel 12. Specifically, the insertion portion 114 and the sealing barrel 12 can be sealed together.

[0049] The length of the waterproof isolation cylinder 13 is aligned with the direction in which the temporary storage shell 11 can slide relative to the sealing barrel 12. One end of the waterproof isolation cylinder 13 is connected to the outward portion 115, which seals the opening at that end of the waterproof isolation cylinder 13. Essentially, the end of the waterproof isolation cylinder 13 connected to the outward portion 115 is sealed, preventing water from entering from this end.

[0050] The sealing barrel 12 is located inside the waterproof isolation cylinder 13. The sealing barrel 12 is slidable relative to the waterproof isolation cylinder 13. A sealing ring 124 is provided between the sealing barrel 12 and the waterproof isolation cylinder 13.

[0051] Therefore, as Figure 1 and Figure 2 As shown, the waterproof isolation cylinder 13, the temporary storage shell 11, the sealing barrel 12, and the sealing ring 124 together form a sealed space. When relative sliding occurs between the temporary storage shell 11 and the sealing barrel 12, the volume of this sealed space will change.

[0052] Specifically, the sustained-release hole 112 can be formed on the extended portion 115, for example, the sustained-release hole 112 is located on the extended portion 115 at a position directly opposite the sustained-release wall 113.

[0053] like Figures 1 to 3 As shown, in some embodiments, the temporary storage housing 11 and the waterproof isolation cylinder 13 are integrally formed and connected. The temporary storage housing 11 and the waterproof isolation cylinder 13 can be integrally injection molded, or formed by stamping from a single material, etc.

[0054] In one embodiment, such as Figure 1 and Figure 2 As shown, the space enclosed by the outward-extending portion 115 is a columnar structure, and the space enclosed by the insertion portion 114 is also a columnar structure. The outer diameter of the outward-extending portion 115 is larger than the outer diameter of the insertion portion 114. The outer diameter of the waterproof isolation cylinder 13 is the same as the outer diameter of the outward-extending portion 115. The outer diameter of the sealing cylinder 12 is located between the outer diameter of the insertion portion 114 and the outer diameter of the waterproof isolation cylinder 13. Therefore, the sealing cylinder 12 can be inserted into the gap between the insertion portion 114 and the waterproof isolation cylinder 13.

[0055] Furthermore, in some embodiments, such as Figures 1 to 3 As shown, the waterproof isolation cylinder 13 is provided with an end wall 131, which is located on the side of the extrusion force-bearing part 123 away from the slow-release wall 113, and the extrusion member 14 acts between the end wall 131 and the extrusion force-bearing part 123.

[0056] Specifically, the extrusion member 14 can be an elastic member, for example, the elastic member is extruded between the end wall 131 and the extrusion force-bearing part 123. Figure 1 As shown, when the slow-release module 10 is first placed into the water outlet channel 21, there is a large amount of slow-release material 15, and the elastic element is in a compressed state with a large compression amount. Figure 2As shown, as the slow-release material 15 is consumed, the compression of the elastic element decreases, pushing the sealed container 12 upwards. This reduces the volume of the sealed cavity 121, causing the slow-release material 15 to be compressed onto the slow-release wall 113. The common area between the slow-release cavity 111 and the sealed cavity 121 remains constant—the slow-release wall 113. Furthermore, the volume of the slow-release cavity 111 and the volume of the functional solution 16 it contains remain constant throughout this process. When the water outlet device 20 is used regularly, the interval between two uses will not differ significantly, resulting in a relatively consistent release time for the slow-release material 15. With the volume of the slow-release cavity 111 remaining constant, the density of the functional solution 16 will not change significantly, thus ensuring a relatively consistent overall effectiveness of the slow-release module 10.

[0057] Specifically, the water outlet device 20 can be a shower head, faucet, smart toilet, bathtub, water heater, or various types of pipes.

[0058] In devices such as water heaters that operate at high temperatures, the components of the slow-release module 10, including the temporary storage shell 11, the sealed tank 12, the waterproof isolation cylinder 13, and the sealing ring 124, can be made of high-temperature resistant materials.
