[0030] Example

[0031] Combination Figures 1 to 7 The present embodiment provides a water outlet switching structure of a pull-out head, comprising a shell 11, a water inlet joint 12, a center bolt 13 connected to the water inlet joint 12, and a water channel assembly 14 sleeved on the center bolt 13 and movable along the axial direction of the pull-out head 1; wherein the shell 11 is adaptively connected to the water channel assembly 14, the center bolt 13 is provided with a water inlet channel communicating with the water inlet joint 12, and the water channel assembly 14 has a first water channel and a second water channel; by driving the shell 11, the water channel assembly 14 can be driven to move relative to the center bolt 13, so that the water inlet channel is connected to the second water channel, and the connection state with the second water channel is maintained under the action of external tension or water pressure, and when the shell 11 is reset, the water channel assembly 14 moves synchronously, and at this time, the water inlet channel is connected to the first water channel, thereby realizing water channel switching.

[0032] It should be noted that in this embodiment, the waterway assembly 14 is driven by the housing 11 to move and switch the waterway, and there is no need to set a switch structure such as a button on the appearance part, thereby effectively avoiding dirt and grime, and making cleaning convenient. At the same time, it avoids the restriction of the button structure on the appearance and the problem of accidental touch during use.

[0033] In a preferred embodiment, it further includes a connector 15 and a bushing 16, wherein the connector 15 is used to connect the water inlet connector 12 and the pull-out tube, and the bushing 16 is used to connect with the faucet body 2. The connector 15 is provided with a first clamping portion 151, and the bushing 16 is provided with a second clamping portion 161. When the pull-out head 1 is pulled out of the faucet body 2, the first clamping portion 151 is separated from the second clamping portion 161, and when the pull-out head 1 is hung on the faucet body 2, the first clamping portion 151 is engaged with the second clamping portion 161. Preferably, the first clamping portion 151 is set as a groove arranged along the circumference of the outer wall of the connector 15, and the second clamping portion 161 is set as a convex portion arranged along the circumference of the inner wall of the bushing 16. Among them, the cross section of the groove can be an arc shape, and the convex portion is arranged in the same shape as the groove, so as to reduce the resistance of the pull-out head 1. In other embodiments, a first magnetic component may be provided on the bushing, and a second magnetic component may be provided on the housing. When the pull-out head 1 is pulled out of the faucet body 2, the first magnetic component is separated from the second magnetic component, and when the pull-out head 1 is hung on the faucet body 2, the first magnetic component is attracted to the second magnetic component. Preferably, at least one of the first magnetic component and the second magnetic component is a magnet. For example, a magnet is provided at the end of the housing 11 close to the faucet body 2, and the bushing 16 is provided with a metal material that can be magnetically attracted, so that the pull-out head 1 is hung on the faucet body 2 by magnetic attraction. In other embodiments, two magnets may also be used, which is not limited to this and is not specifically limited.

[0034] In another embodiment, the connecting member 15 is trumpet-shaped, and the connecting member 15, the center bolt 13 and the water inlet connector 12 are connected in sequence by threads. An elastic member 17 is arranged between the shell 11 and the water inlet connector 12, and the elastic member 17 is preferably a spring. When in use, the user can pull out the pull-out head 1 by hand. Since the first clamping portion 151 and the second clamping portion 161 are initially engaged, the shell 11 compresses the spring to drive the waterway assembly 14 to move downward. After the pull-out head 1 is pulled out, it is subjected to the pulling force of the weight assembly on the pull-out tube, thereby maintaining the water inlet channel and the second waterway conduction. When the user lets go and releases the pull-out head 1, the pull-out head 1 returns to the initial position under the action of the weight assembly and is hung on the faucet body 2. At this time, the shell 11 is reset under the elastic force of the spring, that is, it moves upward relative to the center bolt 13, so that the water inlet channel and the first waterway are conducted.

[0035] It should be mentioned that the trumpet-shaped connecting member 15 has a guiding function so that the pulling head 1 can be quickly aligned when resetting.

[0036] On the basis of the above embodiments, in an optional embodiment of the utility model, the waterway assembly 14 includes an upper waterway 141 and a lower waterway 142, the side wall of the center plug 13 is provided with a water outlet 131 connected to the water inlet channel, and the upper end and the lower end of the water outlet 131 are respectively provided with a first seal 132 and a second seal 133, when the second seal 133 is sealed with the lower waterway 142, the water outlet 131 is connected to the first waterway, or when the first seal 132 is sealed with the upper waterway 141, the water outlet 131 is connected to the second waterway. The water outlet end of the housing 11 is provided with a water outlet panel 144, the middle part of the water outlet panel 144 is provided with a first water outlet hole, and a second water outlet hole is arranged along the circumference of the first water outlet hole, the first water outlet hole is connected to the first waterway, and the second water outlet hole is connected to the second waterway. Preferably, the first water outlet hole discharges soft water, which can be columnar water with a bubbler, and the second water outlet discharges shower water. Exemplarily, a first water passage and a second water passage are provided on the water outlet panel 144 , and the water outlet holes are arranged on the side of the water outlet panel 144 facing the user and are connected to the water passages in a one-to-one correspondence.

[0037] In another embodiment, the water channel assembly 14 further includes a water flow member 143 adapted to be connected to the sewer 142, and the water flow member 143 has a first water flow channel for communicating with the first water channel and a second water flow channel for communicating with the second water channel, wherein the first water flow channel is arranged along the center of the water flow member 143, and the second water flow channel is arranged along the periphery of the first water flow channel. The first water outlet hole on the water outlet panel 144 is connected to the first water flow channel, and the second water outlet hole is connected to the second water flow channel. During assembly, the water outlet panel 144 is threadedly connected to the housing 11 so that the water flow member 143 is pressed tightly inside the housing 11.

[0038] In other embodiments, the waterway assembly 14 further includes a gland 145, one end of which is fixedly connected to the upper waterway 141, and the other end is sleeved in the guide groove of the water inlet joint 12, which plays a role of sealing and guiding. Exemplarily, the water outlet panel 144 is fixedly connected to the housing 11 by threads, and is pressed under the upper waterway 141 and the lower waterway 142, so that the upper waterway 141 is pressed inside the housing 11; the gland 145 is fixedly connected to the upper waterway 141 by threads. Among them, the water inlet joint 12 and the center bolt 13 are relatively fixedly connected to form a fixed part, and the housing 11, the water outlet panel 144, the upper waterway 141, the lower waterway 142 and the gland 145 are relatively fixedly connected to form a movable part that can move axially up and down relative to the fixed part.

[0039] For example, under normal conditions, the pull head 1 is hung on the faucet body 2 by the pulling force transmitted by the connecting member 15 and the heavy hammer assembly. When the faucet body 2 is flowing with water, the outer shell 11 of the pull head 1 is gently pulled to overcome the elastic force of the elastic member 17, that is, to meet the force required for the pull head 1 to switch the water path, and the movable part moves downward relatively. Since the pulling force at this time is less than the pulling force of the heavy hammer assembly and the force of the first clamping part 151 and the second clamping part 161, the pull head 1 is still hung on the faucet, and the water is switched to shower water, and the shower water outlet state is maintained under the action of the water pressure; after the water is turned off, it automatically resets to the soft water outlet state under the action of the elastic member 17; or the shower water is switched back to soft water by pushing up the outer shell 11 of the pull head 1. When the pull-out head 1 is pulled out with increased force, the elastic force of the elastic member 17 is also overcome during the process of the pull-out head 1 being pulled out, and the water channel is automatically switched to shower water; the water can also be reset to soft water when the water is turned off, or the pull-out head 1 can be returned to the faucet body 2 to automatically switch back to soft water.

[0040] It should be mentioned that, in the present embodiment, the user can automatically switch the shower water of the pull-out head 1 while pulling, and automatically switch back to soft water when returning to its position, which simplifies the user's operation logic and is easy to use. When the pull-out head 1 is hung on the faucet body 2, the water splash can be switched back and forth by gently pulling and pushing back. In summary, in the present embodiment, no matter what state the pull-out head 1 is in (hanging on the faucet body 2 or pulling out of the faucet body 2), the water can be turned off and automatically reset to soft water. The action of switching the water splash after the user pulls is simplified, and the water outlet is automatically switched while pulling, which improves the inconvenience of pulling and pressing to switch the water splash during one-handed operation, and also avoids the problem of accidental touch during pulling. In addition, by optimizing the water channel structure, the water pressure balance of the dual water channels is achieved, the switching force is uniform, and the switching force is small.

[0041] Combination Figure 8 The utility model further provides a pull-out faucet, comprising a faucet body 2 and a pull-out head 1 arranged on the faucet body 2, wherein the pull-out head 1 performs water outlet switching via a water outlet switching structure, and the water outlet switching structure is the water outlet switching structure of the pull-out head as described in any of the above embodiments. Exemplarily, the faucet body 2 comprises a bend pipe 21 and a valve body, the pull-out head 1 is connected to the pull-out pipe, a weight assembly is arranged on the pull-out pipe, and the water flow switch, flow rate and temperature regulation are controlled by the valve body.
