Description

Technical Field

[0001] The utility model relates to a faucet pull-out head structure, in particular to a faucet pull-out head structure with compact structure and reliable self-reset. Background Art

[0002] Faucets are something that families come into contact with almost every day. Frequent use increases people's demand for them. With the development of the bathroom industry, there are more and more faucet styles, and the water outlet of the faucet is no longer limited to the traditional fixed way of discharging water.

[0003] Currently, pull-out faucets are widely used, and their convenient pull-out design brings many benefits. Existing double-reset pull-out faucets rely on components such as a gravity hammer located below the faucet body. To ensure a sufficient pull-out range, the pull-out hose needs to be lengthened, which increases the production cost of the faucet. Furthermore, the gravity hammer is typically located below the sink, and a lengthy pipe is installed between the pull-out head and the gravity hammer, further increasing costs. Common reset-type pull-out faucets on the market are prone to difficulty resetting after running water. Therefore, ensuring stable and rapid resetting is an urgent issue to be addressed by the present invention. Utility Model Content

[0006] A spring is provided between the water inlet end of the pull-out tube connected to the spring tube and the water inlet end fixing block; when the pull-out head is pulled outward relative to the faucet outer tube, the pull-out tube and the spring tube move forward in the positive direction along the length direction of the faucet outer tube, and the spring is in a stretched state at this time; when the pull-out head is released, the pull-out tube and the spring tube move backward in the opposite direction, and the spring recovers from the stretched state to the initial unstretched state under the action of the spring force.

[0007] Preferably, the spring tube and the spring have the same shape. When the pulling head of the spring tube is pulled outward relative to the faucet outer tube, the length of the spring tube becomes longer as the spring stretches. When the pulling head of the spring tube is released, the length of the spring tube becomes shorter as the spring retracts and returns to its initial length.

[0008] Preferably, the spring is arranged inside the spring tube or outside the spring tube.

[0009] Preferably, the spring and the spring tube are integrally formed of rubber and plastic.

DETAILED DESCRIPTION

[0026] The faucet pull-out head structure of the present invention is connected to the faucet body 11, and includes a faucet outer tube 1 connected to the faucet body, a pull-out head 2 arranged at the end of the faucet outer tube 1 away from the faucet body, an internal hollow pull-out tube 3 arranged inside the faucet outer tube 1 and connected to the pull-out head 2 at one end, and a spring tube 4 connected to the end of the pull-out tube 3 away from the pull-out head 2 and internally hollow. A water inlet end fixing block 5 fixedly installed at the end of the faucet outer tube 1 is provided on the end of the faucet outer tube 1 connected to the faucet body, and the end of the spring tube 4 away from the pull-out tube 3 is installed on the water inlet end fixing block 5. The water inlet end fixing block 5 is provided with a water inlet hole 51 that passes through from top to bottom. The faucet body, the water inlet hole 51 on the water inlet end fixing block 5, the spring tube 4, the pull-out tube 3 and the pull-out head 2 form a water outlet channel.

[0027] A spring 6 is installed between the water inlet end of the pull-out tube 3 and the water inlet fixing block 5, where the pull-out tube 3 is connected to the spring tube 4. When the pull-out head 2 is pulled outward relative to the faucet outer tube 1, the pull-out tube 3 and the spring tube 4 move forward along the length of the faucet outer tube 1, and the spring 6 is in a stretched state. When the pull-out head 2 is released, the pull-out tube 3 and the spring tube 4 move backward in the opposite direction, and the spring 6 returns from the stretched state to its initial unstretched state under the action of the spring force.

[0028] With this structure, a spring tube 4 and a pull tube 3 are positioned within the faucet outer tube 1, between the water outlet of the faucet body and the pull head 2. A water inlet fixing block 5 is located at the lower end of the faucet outer tube 1. The faucet body, the water inlet hole 51 in the water inlet fixing block 5, the spring tube 4, the pull tube 3, and the pull head 2 form a water outlet channel.

The lower joint 7 is threadedly fitted in the water inlet hole 51, and the lower joint 7 is interference fit in the spring tube 4. A lower joint sealing ring for sealing is provided between the lower joint 7 and the water inlet end fixing block 5.

[0031] The water inlet fixing block 5 of the present invention includes a large circular surface 52 that rests on the end of the faucet outer tube, a connecting portion 53 arranged above the large circular surface 52 and embedded in the faucet outer tube, the connecting portion 53 is a cylindrical structure, and a water inlet sealing ring is provided between the connecting portion 53 and the inner wall of the faucet outer tube for sealing.

[0032] The end of the above-mentioned drawing tube connected to the spring tube 4 is provided with a fixing plate 8 fixedly mounted on the drawing tube 3. The fixing plate 8 is a hollow circular structure. The end of the spring 6 close to the drawing tube 3 is connected to the fixing plate 8. The drawing tube 3 is threaded with a clamping ring 9 that abuts against the end face of the fixing plate 8. The clamping ring 9 is a hollow cylindrical structure and is located below the fixing plate 8.

[0033] An upper joint 10 connecting the drawing tube 3 and the spring tube 4 of the present invention is provided between the drawing tube 3 and the spring tube 4. The upper joint 10 is threadedly fitted in the drawing tube 3 and interference fit in the spring tube 4. An upper joint sealing ring is provided between the upper joint 10 and the spring tube 4 for sealing.

[0034] The specific working process is: when the pulling head 2 is pulled outward relative to the faucet outer tube 1, the pulling tube 3 and the spring tube 4 move forward together along the length direction of the faucet outer tube 1, and the spring 6 is in a stretched state; when the pulling head 2 is released, the pulling tube and the spring tube 4 move backward together, and the spring 6 recovers from the stretched state to the initial unstretched state under the action of the spring force.

[0035] The above embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
