Description

Technical Field

[0001] This utility model relates to the field of kitchen and bathroom appliances, and more specifically, to an easy-to-clean pull-out faucet. Background Technology

[0002] Currently, pull-out faucets on the market use a non-removable structure, and their aerators are prone to clogging, resulting in low water flow or even complete blockage and unusability. Therefore, they have high requirements for water quality; otherwise, the product's lifespan will be greatly affected.

[0003] Secondly, due to limitations in structural design, the flow rate of small pull-out faucets with a diameter of 24mm is currently too small to meet the requirements for large flow rates.

[0004] To address the above problems, this utility model provides a better structural solution. Utility Model Content

[0005] The purpose of this invention is to provide an easy-to-clean pull-out faucet that facilitates cleaning and maintenance and extends the product's service life.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An easy-to-clean pull-out faucet includes a housing and an inlet connector, a spindle, a switching structure, an aerator, a water outlet screen, and a pressure ring disposed within the housing. The spindle has an inlet end and an outlet end, and an inlet channel, a first branch channel, and a second branch channel are provided between the inlet end and the outlet end. The first branch channel is connected to the aerator, and the second branch channel is connected to the water outlet screen. The switching structure is disposed on the spindle between the inlet channel and the first and second branch channels. The inlet connector is engaged with the inlet end of the spindle, and the water outlet screen is connected to the outlet end of the spindle, limiting the aerator to the outlet end of the spindle. The pressure ring is screwed to the housing, limiting the water outlet screen to the outlet end of the spindle.

[0008] Preferably, the switching structure includes a central plug, a spring, a central plug base, and a button. The central plug base is located at the water outlet end of the spindle, above the aerator. The spring is provided between the central plug base and the central plug. The head of the central plug is connected to the button.

[0009] Preferably, the mandrel includes an inner chamber and an outer chamber, with the outer chamber partially covering the inner chamber. The inner chamber is used for coaxial mounting of the center bolt, and the outer chamber is used to form the water inlet channel.

[0010] Preferably, the button includes a rocker and a connecting rod, wherein the rocker has a C-shaped bayonet, the spindle is provided with a connecting seat, and the connecting seat is provided with pivots protruding to both sides for engaging with the C-shaped bayonet.

[0011] Preferably, the connecting rod is a hollow column with an opening on one side, and the head of the central bolt is spherical. The head of the central bolt is embedded from the bottom of the hollow column, thereby connecting with the connecting rod.

[0012] Preferably, the water outlet mesh is a single row of fine holes or a double row of coarse holes.

[0013] Preferably, a gasket is provided between the aerator and the center plug base.

[0014] Preferably, the outer end face of the pressure ring is provided with evenly distributed slots.

[0015] The beneficial effects of this utility model are:

[0016] Except for the spiral connection between the pressure ring and the outer shell, the rest of this invention uses a snap-fit ​​connection. Therefore, it is convenient to disassemble the main body located at the water outlet of the spindle for cleaning and maintenance, reducing the adverse impact of water quality issues on the product's service life.

[0017] The center pin and center pin base are directly assembled at the internal center of the mandrel, without occupying a separate space in the diameter direction. The internal space of the mandrel is utilized to the fullest extent, resulting in an extremely small overall shape.

[0018] Because the pressure ring and the outer shell are connected by a spiral, the main body located at the water outlet end of the spindle is easy to disassemble. As a result, the water outlet screen can be configured with either a single row of fine holes or a double row of coarse holes, which is convenient for users to choose and increases the versatility of the product's functions.

[0019] The central throttle is installed in the center of the inlet channel. The water path splits from the upper and lower sides of the central throttle to form the first branch channel and the second branch channel, which can maximize the cross-section of the water path and achieve a large diameter and large flow rate of water output.

[0035] like Figure 1 and Figure 2 As shown, an easy-to-clean pull-out faucet includes a housing 1 and an inlet connector 2, a spindle 3, a switching structure 4, an aerator 5, a water outlet screen 6, and a pressure ring 7 disposed within the housing 1.

[0036] Among them, such as Figure 9 As shown, the spindle 3 has an inlet end 31 and an outlet end 32, and an inlet channel L, a first branch channel L1 and a second branch channel L2 are provided between the inlet end 31 and the outlet end 32. The first branch channel L1 is connected to the aerator 5, and the second branch channel L2 is connected to the outlet network 6. The inlet connector 2 is engaged with the inlet end 31 of the spindle 3.

[0037] The switching structure 4 is located on the spindle 3, between the inlet channel L and the first branch channel L1 and the second branch channel L2. The spindle 3 includes an inner chamber 301 and an outer chamber 302, with the outer chamber 302 partially covering the inner chamber 301. The switching structure 4 includes a central plug 41, a spring 42, a central plug base 43, and a button 44. The inner chamber 301 is used to coaxially mount the central plug 41, and the outer chamber 302 is used to form the inlet channel L. The central plug base 43 is located at the outlet end of the spindle 3, above the aerator 5, and a gasket 8 is provided between the aerator 5 and the central plug base 43. A spring 42 is provided between the central plug base 43 and the central plug 41, and the button 44 is connected to the head of the central plug 41.
