Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, features in the following embodiments can be combined with each other.

[0020] Combination Figures 1 to 9 In one embodiment, the compact faucet of this application includes a base 1, a main body component 2, a water flow control component 3, and a fixing device 4.

[0021] The base 1 is suitable for installation on a countertop P with mounting holes P1, such as a common marble countertop used in kitchens. In this embodiment, the base 1 has a sleeve 1A and a base 1B. A transverse mounting portion for installing the water flow control assembly 3 is provided on the outer periphery of the sleeve 1A, and the base 1B is located below the sleeve 1A; the two are detachably joined. Figure 10 The base component 1B has positioning blocks N spaced apart along the circumference. The size of the outer periphery of the positioning block N is adapted to the size of the mounting hole P1 to facilitate the installation position of the positioning base 1. A through hole S is formed between the positioning blocks N of the base component 1B for the conduit to pass through.

[0022] In this embodiment, the main component 2 is the part where water flows. It is a common pull-out type and includes a water channel body 2A, a cold water conduit 2B, a hot water conduit 2C, a mixing water conduit 2D, a faucet body 2E, a pull-out conduit 2F, a counterweight 2G, and a water outlet 2H. The water channel body 2A is installed inside the sleeve 1A of the base 1. When the base 1B is separated from the sleeve 1A, the water channel body 2A can be removed from the underside of the sleeve 1A. The water channel body 2A has a water flow channel, a common component of faucets, and will not be described further. The cold water conduit 2B, hot water conduit 2C, and mixing water conduit 2D are connected to the water channel body 2A, respectively for supplying cold water inflow, hot water inflow, and mixed water outflow. The faucet body 2E is rotatably mounted on the lower side of the sleeve 1A of the base 1 via a coupling Q. The faucet body 2E has a connecting hole G, and the coupling Q has a spring-loaded engaging part Q1. When the faucet body 2E is sleeved on the coupling Q, the faucet body 2E is connected to the coupling Q by the spring-loaded engaging part Q1 engaging the connecting hole G. When it is necessary to separate the faucet body 2E, the engaging part Q1 is pressed to disengage it from the connecting hole G. One side of the pull-out conduit 2F passes through the faucet body 2E and is connected to the water outlet 2H. The water outlet 2H can be a water outlet with various water outlet modes, which will not be described in detail. The other side of the pull-out conduit 2F passes through the coupling Q and passes through the water channel body 2A via a hollow screw 4A, and finally connects to the mixing water conduit 2D. The counterweight 2G is located on the underside of the countertop P and is installed on the pull-out conduit 2F. It is used to provide power for the water outlet 2H to move to the faucet body 2E after the water outlet 2H is separated from the faucet body 2E. In this embodiment, the counterweight 2G includes a first part M1 and a second part M2 that are spliced ​​together.

[0023] The water flow control component 3 is mounted laterally on the sleeve 1A. It includes a valve core 3A and a rotating handle 3B. By controlling the rotation of the rotating handle 3B, the valve core 3A can be moved, thereby adjusting the water outlet mode of the mixed water conduit 2D. The water flow control component 3 controlling the water outlet mode of the mixed water conduit 2D is existing technology, so it will not be described in detail.

[0024] The fixing device 4 is used to detachably hold the base 1 on the platform P. It includes a lead screw 4A, a nut 4B, an anti-detachment arm 4C, and a state switching element 4D. The anti-detachment arm 4C and the state switching element 4D form an anti-detachment structure, which is driven by the lifting and lowering movement of the nut 4B, switching between a detachment-allowed state (allowed to detach through the mounting hole P1) and a detachment-restricted state (able to abut against the lower side of the platform). Specifically, in this embodiment, the lead screw 4A is a hollow tube that passes through the base 1 and extends to the lower side of the platform P. Specifically, the lead screw 4A passes through the waterway body 2A, and its upper side is engaged with the coupling Q. The upper side of the lead screw 4A is smooth, while its lower outer circumference has external threads. The nut 4B is sleeved on the lower side of the lead screw 4A, and the two have a mating thread structure. Figure 7 In this embodiment, the nut 4B is constrained by the cold water conduit 2B, the hot water conduit 2C, and the mixing water conduit 2D, and does not rotate with the lead screw 4A. Therefore, the nut 4B can be controlled to move up and down on the underside of the platform P by means of the lead screw 4A rotating while it itself does not rotate. Multiple anti-detachment arms 4C are circumferentially spaced on the nut 4B, and are pivotally connected to the nut 4B, thus allowing it to switch between a retracted and extended state by rotating up and down relative to the nut 4B. (Reference) Figure 7 When in the retracted state, the anti-detachment arm 4C can pass through the mounting hole P1 on the platform P, thereby allowing the base 1 to separate from the platform P; when in the extended state, the anti-detachment arm 4C can abut against the lower side of the platform P, thereby keeping the base 1 fixed on the platform P. The state switching component 4D is used to control the anti-detachment arm 4C to switch from the extended state to the retracted state. The state switching component 4D has a trigger protrusion corresponding to the position of the anti-detachment arm 4C, which is used to push the anti-detachment arm 4C to rotate upward. Specifically, in this embodiment, the state switching component 4D is sleeved on the lead screw component 4A (a bearing may be provided between the two) and is located below the nut component 4B. The state switching component 4D is restricted by the cold water conduit 2B, the hot water conduit 2C, and the mixing water conduit 2D, and does not rotate with the lead screw component 4A. When the nut 4B moves away from the state switching member 4D, the anti-disengagement arm 4C rotates from top to bottom relative to the nut 4B under its own gravity and is in an extended state; when the anti-disengagement arm 4C descends with the nut 4B, the triggering protrusion of the state switching member 4D will push the anti-disengagement arm 4C to rotate upward, thus switching it from the extended state to the retracted state.

[0025] The above describes the specific structure of a faucet according to one embodiment of this application. It should be understood that other variations of the design are also possible. In another embodiment, the nut 4B can be adjusted to be restricted by one or two of the cold water conduit 2B, hot water conduit 2C, and mixing water conduit 2D, and not to rotate with the lead screw 4A. In another embodiment, the state switching member 4D can be adjusted to be restricted by one or two of the cold water conduit 2B, hot water conduit 2C, and mixing water conduit 2D, and not to rotate with the lead screw 4A. In another embodiment, an elastic element can be disposed between the anti-detachment arm 4C and the nut 4B, so that the anti-detachment arm 4C always has a downward rotation tendency; the elastic element is, for example, a torsion spring or a telescopic spring. In another embodiment, the faucet of this application can be adjusted to a non-stretching faucet, i.e., the water outlet 2H cannot separate from the faucet body 2E. In another embodiment, the anti-detachment structure can be adjusted to the linkage structure disclosed in patent application CN201720934519.6.

[0026] The difference from the prior art is that the technical solution of this application makes full use of the existing structure of the faucet by using the limiting nut and state switching component of the water guide pipe to rotate in 4D, making the overall structure more compact.

[0027] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
