Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0031] Referring to the drawings of the specification, a new type of pull-out head 110 with a button-free structure includes a water inlet connector 10 and a center plug 20 that can be connected. The middle parts of the water inlet connector and the center plug both have the function of passing water. A lower shell 30 is arranged on the periphery of the water inlet connector. The lower shell and the upper shell form an outer shell that can form an integral whole. When the two are in the default state, the lower end of the upper shell abuts against the upper end of the lower shell. An inner body is arranged in the lower shell, and the inner body is fixedly connected to the lower shell. The lower shell and the inner body can move up and down synchronously relative to the water inlet connector and the center plug, and the function switching of the water flow is realized through relative movement. A water diversion chamber 40 is arranged in the inner body, and the water diversion chamber is provided with an upper water outlet 41 and a lower water outlet 42. The inner body is provided with a first flow channel 43 that can be connected to the upper water outlet, and the inner body is provided with a second flow channel 44 that can be connected to the lower water outlet. One end of the center plug can be arranged in the water diversion chamber. Inside, a water outlet 21 that can connect the water outlet chamber and the water inlet joint is arranged on the periphery of the center plug located in the water distribution chamber, an upper sealing ring 22 that can cooperate with the upper water outlet is arranged on the outer periphery of the center plug located above the water outlet hole, and a lower sealing ring 23 that can cooperate with the lower water outlet is arranged on the outer periphery of the center plug located below the water outlet hole. When the pull-out head is in the default state, the upper shell and the lower shell are merged and closed. In this state, the lower water outlet cooperates with the lower sealing ring, and water does not pass through the second flow channel. Water flows upward from the water outlet of the center plug and flows out from the upper water outlet through the first flow channel; but when switching is required, the lower shell and the inner body are pulled down relative to the water inlet joint and the center plug. At this time, the upper shell and the lower shell are separated, the upper sealing ring cooperates with the upper water outlet, the first flow channel is disconnected, and the lower water outlet is separated from the lower sealing ring, the contact seal cooperates, and water passes through the second flow channel. Water flows downward from the water outlet of the center plug and flows out from the lower water outlet through the second flow channel.

[0032] Preferably, it also includes an upper shell 50 located on the periphery of the water inlet joint, the upper shell is located at the upper end of the lower shell, and the upper shell is fixedly connected to the water inlet joint. An elastic member 90 is arranged between the lower shell and the upper shell or the water inlet joint, and the elastic member can make the lower shell move upward and reset relative to the upper shell. The elastic member can be a spring, which is arranged between the lower shell and the water inlet joint. When water is flowing, the water pressure can overcome the force of the spring to keep the second flow channel continuously outflowing water. However, when the water is turned off, due to the absence of the water pressure, the spring resets, so that the upper shell and the lower shell are merged and restored to the default water flow state of the first flow channel. The cross-sectional areas of the upper sealing ring and the lower sealing ring can be set to be consistent to ensure the balance of the water pressure. The elastic member can also be a tension spring, which can be arranged between the upper shell and the lower shell.

[0033] Furthermore, a water outlet panel 60 is provided at the lower end of the lower shell, and a first water outlet hole 61 which can be connected to the first flow channel is provided on the water outlet panel, and a second water outlet hole 62 which can be connected to the second flow channel is also provided on the water outlet panel. The initial state of the pull-out head is: water flows through the first flow channel and water is discharged from the first water outlet; when the lower shell moves downward relative to the upper shell (it can also be said that the lower shell moves downward relative to the water inlet joint), the water flow in the first flow channel can be disconnected, and water can flow through the second flow channel and water is discharged from the second water outlet. Preferably, the first water outlet hole is the water outlet hole of the water softener, and the second water outlet hole is the water outlet hole of the shower water. Under normal circumstances, the pull-out head defaults to soft water, which can also be said to be bubble water.

[0034] Furthermore, the inner body includes a gland 70, the upper end of which is provided with a guide strip 71, the lower end of the water inlet joint is provided with a guide groove 11, the guide strip can be inserted into the guide groove and connected therewith. The middle part of the gland can be sleeved on the outer periphery of the center plug, and a sealing ring 24 is provided between the outer periphery of the center plug and the gland, thus achieving the effect of guiding and sealing.

[0035] Preferably, the inner body further comprises a first water channel 81 and a second water channel 82 that match each other, the second flow channel can be distributed at the second water channel, and the first flow channel can be distributed between the first water channel and the second water channel. A water dividing cavity is formed between the first water channel and the second water channel, the upper water outlet is arranged on the first water channel, the lower water outlet is arranged on the second water channel, the first water channel can be arranged on the periphery of the second water channel, and the periphery of the lower end of the gland can be connected to the first water channel.

[0036] The utility model also discloses another technical feature:

[0037] A faucet 100 includes the novel pull-out head 110 with a button-free structure.

[0038] It also includes a pull-out tube 120, which can be arranged in an outer tube 130. The outer periphery of the pull-out tube is sleeved with a gravity hammer 140. The water outlet end of the pull-out tube is provided with a water outlet joint 150, and the water outlet joint is threadedly connected to the water inlet joint; a snap ring 160 is also provided in the outer tube, and the water outlet joint can be snap-fitted with the snap ring.

[0039] Specifically, the utility model designs a new type of pull-out head without buttons, which removes the traditional switching structure, making the appearance simpler, less prone to dirt and grime, and easy to clean; the user's action of switching the water splash when pulling is simplified, and the required water splash can be selectively pulled out, and the water splash can be automatically switched while pulling, which improves the inconvenience of pulling and pressing to switch the water splash when operating with one hand, and avoids accidental touch during the pulling and pulling process. At the same time, the water splash can be switched back and forth with one hand in the pulling and non-pulling states, which is easy to operate. This design achieves double water pressure balance by optimizing the water channel structure, uniform switching force, small switching force, and the water can be automatically reset to the default water splash when turning off the water in any state.

[0040] The pull-out head mainly comprises a water inlet joint, an elastic member, a pressure cover, a center plug, a first water channel, a second water channel, a water outlet panel, an upper shell and a lower shell of the pull-out head and other parts, wherein the center plug is fixedly connected to the water inlet joint, and a water passage is left in the middle of the center plug; the upper shell of the pull-out head is fixedly connected to the water inlet joint by a thread; the lower shell of the pull-out head can be sleeved on the outer periphery of the water inlet joint for relative axial movement, and the elastic member is placed between the water inlet joint and the lower shell of the pull-out head; the first water channel is fixedly connected to the second water channel, forming a first upward flow channel and a second downward flow channel therebetween, and the water outlet of the water channel in the middle of the center plug is placed in a water diversion chamber; the water outlet panel is fixedly connected to the lower shell of the pull-out head, and its two water outlet holes are connected to the two flow channels respectively, and the water outlet panel simultaneously presses the first water channel and the second water channel against the internal step of the lower shell of the pull-out head; the pressure cover is fixedly connected to the first water channel by a thread, and the other end is sleeved in the guide groove of the water inlet joint to play a sealing and guiding role. In summary, the upper shell of the pull-out head, the water inlet joint and the center bolt are relatively fixedly connected to form a fixed part, while the lower shell of the pull-out head, the water outlet panel, the first water channel, the second water channel and the gland are relatively fixedly connected to form a movable part that can move up and down axially relative to the fixed part. When the movable part moves upward relative to the fixed part, the first flow channel is connected and the second flow channel is closed; when the movable part moves downward relative to the fixed part, the second flow channel is connected and the first flow channel is closed.

[0041] The pull-out head is threadedly connected to the water outlet joint of the pull-out tube through the water inlet joint, and the outer periphery of the water outlet joint can be fixed with the buckle ring through the matching relationship of the buckle, and the buckle ring is fixed on the outer tube. Therefore, under normal conditions, the pull-out head is hung on the outer tube of the faucet through the water outlet joint and the pulling force transmitted by the gravity hammer through the pull-out tube. At this time, the faucet is flowing with water, and under the action of the spring, the pull-out head emits a default water splash; gently pull the lower shell of the pull-out head to overcome the spring elastic force, that is, to meet the force required for the pull-out head 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 gravity hammer and the force of the buckle of the water outlet joint and the buckle ring, the pull-out head is still hung on the faucet, and the water splash is switched to another water splash, and can be maintained under the action of water pressure; after turning off the water, it can automatically reset to the default state under the action of the spring; or push up the outer shell of the pull-out head to switch the water splash back to the default water splash. Alternatively: the pull-out head is threadedly connected to the water outlet joint of the pull-out tube through the water inlet joint, and the pull-out tube is provided with a gravity hammer; the buckle ring is fixed to the outer tube of the faucet, and a magnet is provided on one end of the upper shell of the pull-out head and the buckle ring, and a magnetic attraction piece is provided on the other end, that is, when the pull-out head returns to its original position, the upper shell and the buckle ring are tightly attached by magnetism. Therefore, under normal conditions, the pull-out head is hung on the outer tube of the faucet by the magnetic force and the pulling force transmitted by the gravity hammer through the pull-out tube. At this time, water is flowing through the faucet, and under the action of the spring, the pull-out head produces a default splash; gently pull the pull-out head shell to overcome the elastic force, that is, to meet the force required for the pull-out head to switch the water path, and the movable part moves downward relatively. Since the pulling force at this time is smaller than the magnetic force and the force of the water outlet connector and the buckle ring, the pull-out head is still hung on the faucet, and the water splash is switched to the beneficial splash and can be maintained under the action of water pressure; after turning off the water, it can automatically reset to the default state under the action of the spring; or push up the pull-out head shell to switch the water splash back to the default splash.

[0042] When you need to pull out the default water splash, you only need to increase the force to pull the upper shell of the pull-out head, and the pull-out head will be pulled out as a whole, and the default water splash will be maintained. The pulling force is only used to overcome the gravity hammer pulling force and the buckle force (or magnetic attraction). When you need to pull out another water splash, you only need to increase the force to pull the lower shell of the pull-out head. When the pull-out head is pulled out, the elastic force of the elastic part is also overcome, and the water path automatically switches to another water splash; turning off the water can also reset to the default water splash, or returning the pull-out head to the outer tube of the faucet, the water path can also automatically switch back to the default water splash.

[0043] The utility model designs a new type of pull-out head, which does not need buttons to control the switching structure, effectively avoids dirt and grime, and is easy to clean. When in use, the user can independently select the required water splash when pulling, that is, the default water splash appears when the upper half of the shell is pulled out, and the second function water splash is automatically switched when the lower half of the shell is pulled out; after pulling, the upper and lower shells can be pushed closer or farther with one hand to switch back and forth between the two water splashes; at the same time, the water splash can be restored to the default water splash while pulling and resetting; when there is no need to pull, the water splash can be switched back and forth by gently pulling and pushing back; the utility model can also realize the automatic reset of the water to the default water splash when the water is turned off, which simplifies the user operation logic and is more convenient to use.

[0044] The above description shows and describes the preferred embodiments of the utility model. As mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field.
