Description

Technical Field

[0001] This utility model relates to a water outlet device that allows for one-button switching of filter media. Background Technology

[0002] With the continuous development of the beauty industry, carbonated spring shampooing has gradually gained attention as an emerging hair care method. However, this technology is currently mainly used in professional beauty salons and is not yet widespread in home environments, making it difficult for ordinary users to enjoy the benefits of carbonated spring shampooing in their daily lives. At the same time, existing pull-out shampoo heads on the market have relatively limited functionality. Although some products have the function of placing filter media, their designs generally suffer from cumbersome operations for adding and replacing filter media, resulting in a poor user experience. Furthermore, traditional pull-out shampoo heads lack convenient operation methods during use and cannot meet users' needs for quick filter media replacement. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a water outlet device that allows for one-button switching of filter media.

[0004] This utility model is achieved through the following technical solution:

[0005] A water outlet device for one-button press-to-switch filter media includes a main body with a water passage cavity and a water outlet, the water passage cavity being connected to the water outlet. It also includes an ejector assembly disposed within the water passage cavity, the ejector assembly being configured to reciprocate axially relative to the main body. The ejector assembly has a cavity for placing filter media, which is connected to the water flow within the water passage cavity. When the ejector assembly is sealed to the main body, the cavity is located within the main body; when the ejector assembly is not sealed to the main body, the cavity is located outside the main body to facilitate filter media replacement. The cavity can reciprocate between the inside and outside of the main body as the ejector assembly reciprocates axially.

[0006] In this embodiment of the invention, the inner peripheral wall of the main body is provided with a guide groove in an annular pattern, and the outer periphery of the ejection assembly is provided with a guide post that can be located in the guide groove. The cooperation between the guide post and the guide groove enables the ejection assembly to reciprocate axially relative to the main body, so that the cavity can reciprocate between the inside and outside of the main body. The movement of the ejection assembly along its pressing direction enables the cavity to be placed inside the main body. The ejection assembly is also provided with a spring, which enables the ejection assembly to move in the opposite direction of its pressing.

[0007] In this embodiment of the present invention, an annular body is provided around the outer periphery of the ejection assembly, the annular body is rotatable relative to the ejection assembly, and a guide post that can move within a guide groove is arranged around the outer periphery of the annular body; the guide groove is arranged in a wave-like shape on the inner peripheral wall of the body.

[0008] In this embodiment of the present invention, the guide groove is provided with a first position and a second position at intervals. When the guide post is in the first position, the cavity can be placed inside the body. When the guide post is in the second position, the cavity can extend out of the body and be placed outside the body. The first position and the second position are located at different axial positions on the inner periphery of the body.

[0009] In this embodiment of the utility model, the body includes a connector and a water channel that are connected to each other. The inner circumference of the water channel is circumferentially arranged with an axially protruding first ratchet tooth facing the connector. The inner circumference of the connector is circumferentially arranged with an axially protruding second ratchet tooth facing the water channel. The tooth tip of the first ratchet tooth and the tooth root of the second ratchet tooth are axially engaged. The tooth root of the first ratchet tooth and the tooth tip of the second ratchet tooth are axially engaged. The guide groove is formed between the first ratchet tooth and the second ratchet tooth.

[0010] In this embodiment of the present invention, one tooth root of the first ratchet forms the first position mentioned above, and another tooth root adjacent to the first tooth root is connected to an axially arranged sliding groove. The sliding groove is disposed on the inner peripheral wall of the waterway. One end of the sliding groove is connected to the other tooth root, and the other end of the sliding groove is configured to form a second position. The guide post can abut against the other end of the sliding groove.

[0011] In this embodiment of the present invention, the outer periphery of the ejection assembly is provided with an axial guide groove, and the inner periphery of the waterway is provided with an axial guide rail. The guide rail can be connected to the guide groove so that the ejection assembly can only move axially relative to the waterway.

[0012] In this embodiment of the invention, a one-way valve is configured on the inner circumference of the connector, and a push rod that can cooperate with the one-way valve is configured on the ejector assembly; when the cavity is located inside the main body, the push rod can open the one-way valve to allow water to flow from the inner circumference of the connector to the water passage cavity; when the cavity is located outside the main body, the push rod can separate from the one-way valve to close the one-way valve, preventing water from flowing from the inner circumference of the connector to the water passage cavity; the water channel is configured to be able to be inserted into the connector, and a sealing element is configured at the connection between the water channel and the connector.

[0013] In this embodiment of the invention, a housing is also included, which is fitted around the outer periphery of the main body. The housing is provided with an installation port that can be adapted to the water outlet.

[0014] In this embodiment of the utility model, an aerator is provided inside the installation port, and the water inlet end of the aerator is configured to be connected to the water outlet.

[0015] The device operates as follows: S1, after the user presses the ejector assembly, the ejector assembly moves axially, and the cavity extends from the main body to the outside of the main body; S2, after the user puts the filter material into the cavity, the user presses the center of the front end of the pull-out head again, and the ejector assembly returns to its initial position, and the cavity is placed back into the main body; S3, the device, through the anti-reverse structure and optimized water flow path design, ensures that the user will not be splashed when replacing the filter material, while ensuring that the water flow fully rinses the filter material.

[0016] This invention achieves rapid filter media replacement and a safe and reliable user experience through the aforementioned technical solution. In particular, the use of a wave-shaped guide groove and annular design allows for more flexible and reliable switching between the cavity inside and outside the main body. Through the ribbed shielding design, most of the water flow passes above the pull-out head, thoroughly rinsing the filter media and ensuring that the outflowing water reaches the expected concentration. Furthermore, this device is not only suitable for washing hair with carbonated spring water but can also be used with other types of filter media, making it widely applicable.

[0017] The beneficial effects of this utility model are as follows: through innovative structural design and optimized operation, it solves the problems of cumbersome filter media addition and inconvenient operation in existing technologies. Specifically, a one-button press operation enables quick filter media replacement, simplifying the user's operation steps; the anti-reverse structure effectively prevents water backflow or splashing, improving safety; the wave-shaped guide groove and annular design make the switching process more flexible and reliable; and the ribbed shielding design optimizes the water flow path, ensuring thorough rinsing of the filter media, thereby improving the user experience. This utility model has significant technical advantages and promising market application prospects. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0027] Referring to the accompanying drawings, this utility model relates to a pull-out head for one-button filter media switching. The specific embodiments of this utility model will be described in detail with reference to the accompanying drawings. In this embodiment, it mainly includes a body 1, an ejector assembly 4, a guide groove 6, a guide post 7, a spring 8, an annular body 9, a first ratchet 10, a second ratchet 11, a sliding groove 12, a guide groove 13, a guide rail 14, a one-way valve 15, a push rod 16, a housing 17, a mounting port 18, and an aerator 19. Through the coordinated design of these components, rapid filter media replacement, optimized water flow path, and improved safety are achieved.

[0028] The main body 1 is equipped with a water passage cavity 2 and a water outlet 3, which are connected to each other to guide the water flow. The ejector assembly 4 is located inside the main body 1 and has a cavity 5 for placing filter media. Ribs (not shown in the figure) can be set in the water passage cavity to make the water flow upward to dilute the filter media as much as possible, and then flow downward from the water outlet. When the ejector assembly 4 is sealed with the main body 1, the cavity 5 is completely placed inside the main body 1. At this time, the cavity 5 is connected to the water flow in the water passage cavity 2, and the water will not flow out, ensuring that the water flows out after passing through the filter media. Preferably, the shell, the main body and one end of the ejector assembly can be flush in this state. Of course, it is also possible to form a concave shape in the middle of the ejector assembly for easy pressing by the user. When the ejector assembly 4 is not sealed with the main body 1, the cavity 5 extends to the outside of the main body 1, making it easy for the user to replace the filter media. The sealing fit can be achieved by a sealing ring 23 on the outer periphery of the ejector assembly.

[0029] The ejection assembly 4 moves relative to the body 1 in the axial direction (lateral direction in the figure). A guide post 7 is radially arranged on its outer periphery. The guide post 7 is embedded in a guide groove 6 arranged annularly on the inner wall of the body 1 and moves along the guide groove 6. The guide groove 6 has a wave-like design. When the guide post 7 moves along the wave-like guide groove 6, it drives the ejection assembly 4 to perform axial displacement. Simultaneously, the resulting rotation is performed by the annular body, thereby achieving the switching of the cavity 5 between inside and outside the body 1. The guide groove 6 is spaced between a first position A1 and a second position A2. When the guide post 7 is in the first position, the cavity 5 is completely placed inside the body 1, and the device is in normal working condition, allowing water to flow out through the filter media inside the cavity 5. When the guide post 7 is in the second position, the cavity 5 extends from inside the body 1 to the outside of the body 1, facilitating filter media replacement by the user. At this time, the one-way valve operates, and water will not flow out.

[0030] The ejection assembly 4 is equipped with a spring 8, one end of which is fixedly connected to the ejection assembly 4, and the other end is fixedly connected to the body 1 or a one-way valve. The spring 8 can be a conical spring. When the user presses the ejection assembly 4 to the right, the spring 8 is compressed; when the pressure is released, the spring 8 returns to its original shape and moves the ejection assembly 4 to the left. An annular body 9 is fitted around the outer periphery of the ejection assembly 4. This annular body can be an open ring, facilitating installation and reducing installation difficulty. The annular body 9 can rotate relative to the ejection assembly 4, and its outer periphery is equipped with guide posts 7, which can move within guide grooves 6. Through the rotation of the annular body 9 and the cooperation of the guide grooves 6, the axial displacement of the ejection assembly 4 and the rotational movement of the annular body are combined. The main body 1 includes a connector 20 and a water channel 21 that are connected to each other. The water channel is configured to be inserted into the connector, and a seal 22 is disposed at the connection between the water channel and the connector. A first ratchet 10 with axial protrusions is arranged circumferentially on the inner periphery of the water channel towards the connector, and a second ratchet 11 with axial protrusions is arranged circumferentially on the inner periphery of the connector 20 towards the water channel. The tip of the first ratchet 10 axially engages with the root of the second ratchet 11, and the root of the first ratchet 10 axially engages with the tip of the second ratchet 11, together forming a guide groove 6. One root of the first ratchet 10 forms a first position, and another root adjacent to this root is connected to an axially arranged sliding groove 12. One end of the sliding groove 12 communicates with the root of the first ratchet, and the other end forms a second position. The guide post 7 can move along the sliding groove 12, thereby realizing the telescoping switching of the cavity 5.

[0031] The ejection assembly 4 has an axial guide groove 13 on its outer periphery and an axial guide rail 14 on its inner periphery. The guide rail 14 and the guide groove 13 are connected to each other to ensure that the ejection assembly 4 can only move axially relative to the water channel, avoiding deviation or jamming. A one-way valve 15 is provided on the inner periphery of the connector, and a push rod 16 is provided on the ejection assembly 4. The push rod 16 cooperates with the one-way valve 15. When the cavity 5 is inside the body 1, the push rod 16 opens the one-way valve 15, allowing water to flow from the inner periphery of the connector into the water passage cavity 2; when the cavity 5 is outside the body 1, the push rod 16 separates from the one-way valve 15, causing the one-way valve 15 to close and prevent water from overflowing. The device also includes a housing 17 sleeved on the outer periphery of the body 1, which protects the internal structure. The housing 17 is provided with an installation port 18, which is adapted to the outlet 3. An aerator 19 is installed inside the mounting port 18. The inlet end of the aerator 19 is connected to the outlet 3 to further optimize the water flow effect.

[0032] The operation process of the device is as follows: S1, when the guide column is in the first position, the user presses the right side of the ejector assembly to the right, the ejector assembly 4 moves to the left along the axis, and the guide column moves towards the root of the second ratchet under the guidance of the inclined surface of the second ratchet. Then, it is released, and under the guidance of the spring and the inclined surface of the first ratchet, the guide column moves to the second position of the guide groove, that is, it slides into the other end of the groove through the root of the first ratchet (not in the first position), and the cavity 5 extends from the body 1 to the outside of the body 1; S2, after the user puts the filter material into the cavity 5, he presses the right side of the ejector assembly to the right, and the guide column returns from the second position to the first position (the movement principle is similar to S1). The ejector assembly 4 is reset to the initial position, and the cavity 5 is placed back into the body 1; S3, the device ensures that the user will not be splashed when replacing the filter material through the anti-reverse structure and the optimized design of the water flow path, while ensuring that the water flow fully rinses the filter material. In operation, the user first presses the ejector assembly 4. Under the pressure, the ejector assembly 4 moves axially, and the guide post 7 moves along the wavy guide groove 6 to the second position. The cavity 5 extends from inside the body 1 to the outside of the body 1, making it easy for the user to remove the old filter media or insert the new filter media. Subsequently, the user releases the pressure, the spring 8 returns to its original state and pushes the ejector assembly 4 back to the initial position, the guide post 7 moves along the guide groove 6 back to the first position, and the cavity 5 is placed back inside the body 1. At this time, the push rod 16 re-engages with the one-way valve 15, the one-way valve 15 opens, and water flows from the inner circumference of the connector into the water cavity 2, passes through the filter media in the cavity 5, and flows out from the outlet 3.

[0033] This invention achieves rapid filter media replacement and a safe and reliable user experience through the above-described technical solutions. The design of the wave-shaped guide groove 6 and the annular body 9 makes the switching of the cavity 5 between inside and outside the body 1 more flexible and reliable. The ribbed shielding design optimizes the water flow path, with most of the water flowing above the pull-out head, thoroughly rinsing the filter media and ensuring that the outflowing water reaches the expected concentration. Furthermore, this device is not only suitable for washing hair with carbonated spring water but can also be used with other types of filter media, making it widely applicable. A one-button press operation enables rapid filter media replacement, simplifying the user's operation. The anti-reverse structure effectively prevents water backflow or splashing, improving safety. The optimized water flow path design ensures thorough rinsing of the filter media, enhancing the user experience. This invention has significant technical advantages and promising market application prospects.
