Technical Field

[0001] This utility model relates to the field of water purifier faucet technology, specifically to a pull-out water purifier faucet. Background Technology

[0002] Existing faucet products have significant limitations in their functional design. On the one hand, some faucets only have a pull-out function. While this feature improves convenience to some extent, allowing users to perform various cleaning operations in scenarios such as the kitchen or bathroom, like washing the sink or wiping the countertop, it fails to meet the current urgent demand for healthy drinking water. On the other hand, some faucets connect to water purifiers to form water purifier faucets. This design does provide users with higher-quality drinking water and ensures the health and safety of the water, but its lack of a pull-out function limits its application in some complex cleaning tasks.

[0003] As people's living standards continue to improve, their functional demands for faucets are becoming increasingly diversified. Consumers hope to enjoy the convenience of a pull-out faucet and the health benefits of a purified water dispensing function in a single product. However, current faucet products on the market have not yet adequately met this comprehensive need, and how to organically integrate pull-out and purified water dispensing functions has become an urgent problem to be solved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to propose a pull-out water purifier faucet to solve the problems mentioned in the background section above.

[0005] This utility model is achieved through the following technical solution:

[0006] A pull-out water purifier faucet includes a housing, a water outlet bend rotatably connected to the housing, and a pull-out head disposed at the free end of the water outlet bend. The housing has a first mounting cavity and a second mounting cavity. A mixing valve core is disposed in the first mounting cavity, and a Hall effect component is disposed in the second mounting cavity. A mixing pipe is disposed at the water outlet end of the mixing valve core.

[0007] It also includes a pull-out tube, one end of which is connected to the pull-out head, and the other end of which is provided with a first interface and a second interface. The first interface is connected to the mixing pipe, and the second interface is connected to the water outlet of the water purifier.

[0008] The Hall effect assembly includes a bottom cover, a circuit board disposed on the bottom cover, and a knob rotatably connected to the bottom cover. A magnet is embedded in the knob. The circuit board has switch contacts and multiple Hall effect sensors. The knob has a button portion that abuts against the switch contacts. A return spring is provided between the knob and the bottom cover. The water purifier has multiple water output modes. By rotating the knob, when one of the Hall effect sensors senses the magnet, it transmits an electrical signal to the water purifier. The water purifier switches to the corresponding water output mode based on the type of received electrical signal. By pressing the knob, the button portion abuts against the switch contacts and transmits a start signal to the water purifier, causing the water purifier to turn on and output water.

[0009] Furthermore, the pull-out tube includes an outer tube, an inner tube disposed within the outer tube, a connector disposed at the lower end of the outer tube, and a counterweight fixed to the outside of the outer tube. The connector is provided with a first interface and a second interface. The outer tube is connected to the first interface, and the second interface is connected to the inner tube.

[0010] Furthermore, the knob and the bottom cover are respectively provided with a plurality of protrusions and grooves. When the protrusions and the grooves are engaged with each other, the magnet is facing one of the Hall sensors.

[0011] Furthermore, the Hall effect assembly includes a circlip and a set screw. The knob is provided with a guide shaft, which passes through the bottom cover and is engaged by the circlip. The return spring is sleeved on the outer periphery of the guide shaft, and the set screw passes through the housing and is connected to the bottom cover.

[0012] Furthermore, the circuit board is equipped with an indicator light, which is electrically connected to the Hall sensor. When one of the Hall sensors detects a magnet, the indicator light emits a specific light source that shines through the knob.

[0013] Furthermore, the first mounting cavity and the second mounting cavity are arranged symmetrically along the central axis of the housing.

[0014] Furthermore, the number of Hall sensors is four, and correspondingly, the water purifier is equipped with four water output modes: room temperature purified water, 90℃ high temperature purified water, 5℃ cold water purified water, and aerated water.

[0015] The beneficial effects of this utility model are as follows: A pull-out water purifier faucet includes a housing, a water outlet bend rotatably connected to the housing, and a pull-out head disposed at the free end of the water outlet bend. The housing has a first mounting cavity and a second mounting cavity. A mixing valve core is disposed in the first mounting cavity, and a Hall effect sensor is disposed in the second mounting cavity. The water outlet end of the mixing valve core is provided with a mixing pipe. It also includes a pull-out tube, one end of which is connected to the pull-out head, and the other end of which is provided with a first interface and a second interface. The first interface is connected to the mixing pipe, and the second interface is connected to the water outlet end of the water purifier. The Hall effect sensor includes a bottom cover, a circuit board disposed on the bottom cover, and a knob rotatably connected to the bottom cover. The knob has a pre-embedded magnet. The circuit board is provided with switch contacts and multiple Hall effect sensors. The knob is provided with an abutment switch contact. The button section has a return spring between the knob and the bottom cover. The water purifier has multiple water outlet modes. By rotating the knob, when a Hall sensor senses the magnet, it transmits an electrical signal to the water purifier. The water purifier switches to the corresponding water outlet mode according to the type of received electrical signal. By pressing the knob, the button section abuts against the switch contact and transmits a start signal to the water purifier, causing the water purifier to start dispensing water. Through the above structure, the pull-out water purifier faucet of this utility model achieves the pull-out function through the cooperation of the pull-out tube and the pull-out head. The water outlet mode of the water purifier can be selected by the knob, making it versatile in use. The regular water flowing out of the mixing valve core and the purified water flowing out of the water purifier are respectively connected through the first interface and the second interface, and the two do not interfere with each other. When the mixing valve core or the water purifier fails, it will not affect the normal water supply of the other component. Attached Figure Description

[0022] 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. It should be noted that the description of these embodiments is intended to aid in understanding this utility model, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Reference Figures 1 to 4 As shown, a pull-out water purifier faucet includes a housing 1, a water outlet bend 2 rotatably connected to the housing 1, and a pull-out head 3 disposed at the free end of the water outlet bend 2. The housing 1 has a first mounting cavity 11 and a second mounting cavity 12. A mixing valve core 4 is disposed in the first mounting cavity 11, and a Hall effect sensor 5 is disposed in the second mounting cavity 12. The water outlet end of the mixing valve core 4 is provided with a mixing pipe 41. It also includes a pull-out pipe 6, one end of which is connected to the pull-out head 3, and the other end of which is provided with a first interface 631 and a second interface 632. The first interface 631 is connected to the mixing pipe 41, and the second interface 632 is connected to the water outlet end of a water purifier (not shown in the figure). The Hall effect sensor 5 includes a bottom cover. 51. A circuit board 52 disposed on the bottom cover 51, and a knob 53 rotatably connected to the bottom cover 51. The knob 53 has a pre-embedded magnet 54. The circuit board 52 is provided with switch contacts and multiple Hall sensors. The knob 53 is provided with a button part 532 that abuts against the switch contacts. A return spring 55 is provided between the knob 53 and the bottom cover 51. The water purifier has multiple water outlet modes. By rotating the knob 53, when a certain Hall sensor senses the magnet 54, it transmits an electrical signal to the water purifier. The water purifier switches to the corresponding water outlet mode according to the type of received electrical signal. By pressing the knob 53, the button part 532 abuts against the switch contacts and transmits a start signal to the water purifier, causing the water purifier to start dispensing water.

[0024] The specific usage of this utility model is as follows:

[0025] When a user needs purified water, they can rotate knob 53. When a Hall sensor detects magnet 54, it transmits an electrical signal to the water purifier's processor via wired or wireless transmission. The processor in the water purifier receives and identifies which Hall sensor emitted the electrical signal, and then switches to the corresponding water outlet mode. The user then presses knob 53, causing button 532 on knob 53 to abut against switch contacts. The switch contacts emit a start signal, which is transmitted to the water purifier's processor via wired or wireless transmission. The processor in the water purifier recognizes the start signal and turns on the water outlet, allowing the purified water to flow through the second interface 632 and through the pull-out head 3.

[0026] In order to ensure that the button part 532 can correctly abut the switch contact when the knob 53 is rotated to the corresponding angle, the knob 53 can be provided with a number of button parts 532 equal to the number of Hall sensors, or the circuit board 52 can be provided with a number of switch contacts equal to the number of Hall sensors.

[0027] The mixing valve core 4 is connected to a cold water supply pipe 42, a hot water supply pipe 43, and a mixing pipe 41. When the user needs regular water, cold water and hot water enter the mixing valve core 4 through the cold water supply pipe 42 and the hot water supply pipe 43 respectively, and then flow out through the mixing pipe 41 and into the first interface 631. The user can adjust the temperature or turn the water on and off by rotating the mixing valve core 4. Regular water flows out through the first interface 631 and the pull-out head 3.

[0028] Through the above structure, the pull-out water purifier faucet of this utility model realizes the pull-out function through the cooperation of the pull-out tube 6 and the pull-out head 3, and the water output mode of the water purifier can be selected by the knob 53. The functions and water output modes are diversified to meet the diverse water needs of users.

[0029] The regular water flowing from the mixing valve core 4 and the purified water flowing from the water purifier are respectively connected through the first interface 631 and the second interface 632, and the two do not interfere with each other. This independent water supply design of the mixing valve core 4 and the water purifier demonstrates significant benefits in practical applications. In everyday use scenarios such as the kitchen or bathroom, even if the mixing valve core 4 malfunctions, users can still obtain relatively pure cold water through the water purifier, ensuring the smooth operation of basic needs such as daily cleaning and handwashing. Similarly, when the water purifier fails, users can still mix and adjust hot and cold water through the mixing valve core 4 to meet normal usage needs in non-drinking scenarios in the kitchen, such as cleaning and washing vegetables. This independent design avoids the paralysis of the entire water supply system due to the failure of a single component, thus not affecting the user's normal water usage experience.

[0030] The pull-out tube 6 includes an outer tube 61, an inner tube 62 disposed within the outer tube 61, a connector 63 disposed at the lower end of the outer tube 61, and a counterweight 64 fixed to the outside of the outer tube 61. The connector 63 has a first interface 631 and a second interface 632. The outer tube 61 is connected to the first interface 631, and the second interface 632 is connected to the inner tube 62. This tube-within-a-tube design of the outer tube 61 and the inner tube 62 saves space and, by constructing a completely independent dual-channel water supply system, avoids the potential risk of cross-contamination when purified water and conventional water are mixed in the same water flow channel.

[0031] The pull-out head 3 has a purified water channel (not shown in the figure) connected to the inner pipe 62 and a regular water channel (not shown in the figure) connected to the outer pipe 61. Purified water from the water purifier enters the inner pipe 62 through the second interface 632 and then flows out through the purified water channel. Regular water from the mixing valve core 4 enters the gap between the outer pipe 61 and the inner pipe 62 through the first interface 631 and then flows out through the regular water channel. This structure creates a completely independent dual-channel water supply system.

[0032] The knob 53 and the bottom cover 51 are respectively provided with a plurality of protrusions 531 and grooves 511. When the protrusions 531 and the grooves 511 are engaged with each other, the magnet 54 is aligned with one of the Hall sensors. This structure ensures that the knob 53 achieves precise positioning and feedback during rotation. When the protrusions 531 are successfully inserted into the grooves 511, tactile feedback informs the user that the correct position has been reached.

[0033] The Hall effect assembly 5 includes a circlip 56 and a set screw 57. The knob 53 is provided with a guide shaft. The guide shaft passes through the bottom cover 51 and is engaged by the circlip 56. The return spring 55 is sleeved on the outer periphery of the guide shaft. The set screw 57 passes through the housing 1 and is connected to the bottom cover 51.

[0034] The various components of the Hall assembly 5 are assembled using a shaft retainer 56 and a set screw 57. During assembly, the circuit board 52 is first installed on the bottom cover 51, the magnet 54 is inserted into the knob 53, the return spring 55 is fitted around the outer circumference of the guide shaft, the guide shaft of the knob 53 passes through the bottom cover 51, and is then fixed by the shaft retainer 56. Finally, the rear end of the bottom cover 51 is inserted into the second mounting cavity 12 and fixed by the set screw 57.

[0035] Furthermore, the circuit board 52 is equipped with an indicator light, which is electrically connected to the Hall sensor. When a Hall sensor detects the magnet 54, the indicator light emits a specific light source that shines through the knob 53. This specific light source can be a different color or a different frequency of light. By recognizing the specific light source, the user can determine which water outlet mode the water purifier has switched to, providing a series of intuitive water outlet mode feedbacks. In another embodiment, the user can determine whether the knob 53 has been correctly rotated to the correct position by the color of the specific light source, ensuring that the magnet 54 is aligned with a Hall sensor, thus switching the water purifier to the user's desired water outlet mode.

[0036] The water purifier features four Hall effect sensors, corresponding to four water output modes: room temperature purified water, 90°C high-temperature purified water, 5°C cold water, and aerated water. Correspondingly, there is one protrusion 531 and four recesses 511 spaced 90° apart. The protrusion 531 is located on the knob 53, and the recesses 511 are located on the bottom cover 51. Users can control the water purifier to switch to the corresponding water output mode by rotating the knob 53 90°, making operation convenient. The specific structure of the water purifier is prior art and will not be described in detail here.

[0037] The first mounting cavity 11 and the second mounting cavity 12 are arranged symmetrically along the central axis of the housing 1. The symmetrical layout design can improve the aesthetics of the pull-out water purifier faucet of this utility model.
