DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0044] In view of the defects of the prior art, the utility model realizes that the retained water in the water outlet pipe can be introduced into the wastewater pipe through the drainage pipe, thereby preventing the retained water from flowing back into the water inlet pipe. It can also prevent the liquid retained in the water outlet pipe from coming into contact with the air to breed bacteria, thereby preventing direct drinking from causing harm to the user's body. It can also prevent the temperature of the liquid retained in the water outlet pipe from being too high and scalding the user, thereby increasing the safety of the water dispenser when in use.

[0045] See attached Figure 1 to Figure 4 The present embodiment provides a water outlet for draining retained water, comprising: an inlet pipe 1; an outlet pipe 2; a drainage pipe 3 for communicating with a wastewater pipe; a control valve 4, the control valve being arranged at the intersection of the inlet pipe 1, the outlet pipe 2 and the drainage pipe 3, and being connected with the inlet pipe 1, the outlet pipe 2 and the drainage pipe 3 respectively; the outlet pipe is selectively connected with the inlet pipe 1 and the drainage pipe 3 by rotating the control valve 4, so that the outlet pipe 2, the control valve 4 and the drainage pipe 3 form a drainage channel to drain the retained water in the outlet pipe 2.

[0046] It should be noted that: in the present embodiment, if the water in the water outlet pipe 2 is retained for too long, bacteria will be bred, and direct drinking by the user will cause harm to the user's body; if the water in the water outlet pipe 2 is high-temperature water, direct use by the user will cause scalding of the user. To avoid the above situation, a drainage pipe 3 and a waste water pipe are provided, so that the retained water in the water outlet pipe 2 can be introduced into the waste water pipe through the drainage pipe 3, and the retained water can be prevented from flowing back into the water inlet pipe 1. The liquid retained in the water outlet pipe 2 can also be prevented from contacting with the air to breed bacteria, thereby avoiding harm to the user's body caused by direct drinking. The liquid retained in the water outlet pipe 2 can also be prevented from being too hot and scalding the user, thereby increasing the safety of the water dispenser when in use.

[0047] In this embodiment, the structure of the outlet end of the water outlet pipe 2 is not limited, and it is sufficient to ensure that it can discharge liquid.

[0048] In this embodiment, the water outlet is a faucet or a bathroom shower device.

[0049] In this embodiment, the drainage tube 3 is made of a high temperature resistant material.

[0050] In this embodiment, the water inlet pipe 1 is connected to the water tank, and the water in the water tank can flow out through the water inlet pipe 1, the control valve 4 and the water outlet pipe 2.

[0051] In some possible embodiments, the control valve 4 includes a valve body 41 and a valve core 42 arranged in the valve body 41, the valve core 42 includes a valve core flow channel, and the valve body 41 has a valve body port; the valve core 42 is rotatably connected to the valve body 41, and the valve core 42 rotates relative to the valve body 41 so that the valve core flow channel and the valve body port can be selectively connected. By setting the valve core 42 to be able to rotate relative to the valve body 41, the valve core flow channel and the valve body port can be selectively connected, so that the drainage pipe 4 does not divert the retained water when the water outlet pipe 2 discharges liquid, and the drainage pipe 4 only diverts the retained water when the water outlet pipe 2 is connected to the drainage pipe 3. On the basis of being able to divert the retained water, different states of the water outlet correspond to different valve core 42 positions, so as to avoid the drainage pipe 3 from diverting at the same time when the water outlet pipe 2 is discharging water, thereby avoiding wasting water resources.

[0052] In some possible embodiments, the valve body port includes a first outlet 411, a second outlet 412 and an inlet 413 connected to the water inlet pipe 1, the first outlet 411 is connected to the water outlet pipe 2, and the second outlet 412 is connected to the drainage pipe 3; the first outlet 411 and the second outlet 412 can be connected through a valve core flow channel, and the water outlet pipe 2, the first outlet 411, the second outlet 412, the drainage pipe 3 and the waste water pipe form a drainage flow channel. By setting the first outlet 411, the second outlet 412 and the inlet 413, the water inlet pipe 1, the water outlet pipe 2 and the drainage pipe 3 are respectively connected to one port, thereby avoiding mutual interference between the water in the water inlet pipe 1, the water outlet pipe 2 and the drainage pipe 3, resulting in the failure to achieve the drainage effect of the drainage pipe 3.

[0053] Specifically, a spherical cross section formed by the first outlet 411 , the second outlet 412 , and the inlet 413 is parallel to a spherical cross section where the second connecting hole 414 disposed on the valve body 41 is located.

[0054] In some possible embodiments, the valve core flow channel includes a first flow channel 421, a second flow channel 422 and a third flow channel 423 which are interconnected. The first flow channel 421, the second flow channel 422 and the third flow channel 423 are arranged in sequence, and the first outlet 411, the second outlet 412 and the import 413 are arranged in sequence; the angle between the second outlet 412 and the first outlet 411, the angle between the second outlet 412 and the import 413, the angle between the second flow channel 422 and the first flow channel 421, and the angle between the second flow channel 422 and the third flow channel 423 are all equal. By setting the above angles to be equal, it can be ensured that when the flow channel rotates by a preset angle, it can correspond to one or two outlets, thereby realizing different states of the water outlet.

[0055] Specifically, the preset angle is the angle between the first outlet 411 and the second outlet 412 , and the preset angle is 0-90°. The preset angle is set according to actual conditions and is not limited here.

[0056] Specifically, the preset angle is 0-30°, 0-40°, 10-40°, 30-50°, 60-80° or 70-90°, etc.

[0057] Preferably, the preset angle is 90°.

[0058] Specifically, the valve core flow channel further includes a valve core inner cavity 425 , which is communicated with the first flow channel 421 , the second flow channel 422 , and the third flow channel 423 , respectively, and the valve core inner cavity 425 is arched.

[0059] Specifically, the spherical cross section formed by the first flow channel 421, the second flow channel 422 and the third flow channel 423 is parallel to the spherical cross section where the third connecting hole on the valve core 42 is located.

[0060] In some possible embodiments, the axis of the first flow channel 421 and the axis of the third flow channel 423 are located in the same straight line, and the side of the first flow channel 421 and the third flow channel 423 away from the second flow channel 422 is a solid structure 424 with a plane. By setting the plane, the drainage resistance can be reduced, the drainage speed can be increased, and the retained water can be reduced, thereby avoiding wasting water resources.

[0061] In some possible embodiments, the valve body 41 has a spherical cavity, and the valve core 42 is a spherical structure that matches the spherical cavity; the axis of the first outlet 411 coincides with the axis of the inlet 413 and passes through the center of the spherical cavity; the axis of the first flow channel 421 coincides with the axis of the third flow channel 423 and passes through the center of the spherical structure. By setting the valve body 41 and the valve core 42 to matching spherical structures, it is possible to ensure that the valve core 42 rotates smoothly in the valve body 41, and avoid the control valve 4 being too large and occupying too much space, thereby further reducing the volume occupied by the control valve 4.

[0062] In some possible embodiments, when the valve core 42 rotates to the first flow channel 421 and the first outlet 411 are connected, and the third flow channel 423 and the inlet 413 are connected, the water outlet is in an open state, and the water inlet pipe 1, the inlet 413, the first outlet 411 and the water outlet pipe 2 form a liquid flow channel, allowing the water in the water inlet pipe 1 to flow out from the water outlet pipe 2; when the valve core 42 rotates to the first flow channel 421 and the second outlet 412 are connected, and the second flow channel 422 and the first outlet 411 are connected, the water outlet is in a drainage state and a closed state, that is, the inlet pipe 1, the inlet 413, the first outlet 411 and the outlet pipe 2 form a liquid flow channel, allowing the water in the water inlet pipe 1 to flow out from the outlet pipe 2; The water in the water pipe 1 cannot enter the water outlet pipe 2. The water outlet pipe 2, the first outlet 411, the second outlet 412, the drainage pipe 3 and the waste water pipe form a drainage channel, allowing the retained water in the water outlet pipe 2 to flow out of the waste water pipe. The water outlet state is switched by rotating the valve core 42. When the water outlet is in the drainage state, the drainage pipe 3 can drain the retained water in the water outlet pipe 2. At the same time, the refluxed retained water can also flush the waste water pipe, reducing the scale and bacteria attached to the wall of the waste water pipe, extending the service life of the waste water pipe and reducing the odor of the waste water pipe.

[0063] like Figure 4 As shown, the first flow channel 421, the second flow channel 422 and the third flow channel 423 are arranged in clockwise order, and the first outlet 411, the second outlet 412 and the inlet 413 are arranged in counterclockwise order.

[0064] Specifically, when the water outlet is in the open state, rotate the switch assembly 5 counterclockwise to the locking position, and the water outlet is switched from the open state to the closed state. At this time, the water outlet pipe 2 and the drainage pipe 3 are connected to achieve drainage of the retained water in the water outlet pipe 2; when the water outlet is in the closed state, rotate the switch assembly 5 clockwise to the locking position, and the water outlet is switched from the closed state to the open state, the water inlet pipe 1 and the water outlet pipe 2 are connected, and water flows out of the water outlet pipe 2.

[0065] In some possible embodiments, the water outlet also includes a switch assembly 5 and a shell 6 with a accommodating cavity, and the switch assembly 5 is arranged on the shell 6; a first connecting hole is arranged on the shell 6, one end of the water outlet pipe 2 extends into the first connecting hole and is detachably connected to the shell 6; the control valve 4 is arranged in the accommodating cavity, and part of the switch assembly 5 extends into the accommodating cavity and is connected to the control valve 4. By setting the shell 6, part of the water inlet pipe 1, part of the water outlet pipe 2 and part of the drainage pipe 3 can be set in its accommodating cavity to avoid being exposed and polluted by the external environment, thereby achieving the environmental requirements for the use of the water outlet and ensuring that the water of the water outlet is pollution-free.

[0066] Specifically, the switch assembly 5 includes a handle 51, a handwheel 52 and a handwheel core. The handwheel core and the handle 51 are arranged on the handwheel 52 at intervals. A thread is provided at the end of the handwheel core away from the handle 52. One end of the handwheel core extends into the accommodating cavity and is connected to the control valve 4. Driven by the handle 51, the handwheel 52, the handwheel core and the control valve rotate synchronously to realize the connection between the water inlet pipe 1 and the water outlet pipe 2, the connection between the water outlet pipe 2 and the drainage pipe 3, or the water inlet pipe 1, the water outlet pipe 2 and the drainage pipe 3 are not connected.

[0067] In some possible embodiments, a second connecting hole 414 is provided on the valve body 41, and a third connecting hole corresponding to the second connecting hole 414 is provided on the valve core 42; the third connecting hole is a threaded hole, and the axis of the second connecting hole 414 passes through the center of the control valve 4; the switch assembly 5 is provided with an external thread matching the third connecting hole, and part of the switch assembly 5 extends into the accommodating cavity, the second connecting hole 414 and the third connecting hole in turn, and is threadedly connected to the third connecting hole. The switch assembly 5 and the valve core 42 are threadedly connected, so that they can be replaced separately, thereby reducing the replacement cost.

[0068] In some possible embodiments, the water outlet further includes a controller, a display component 7 and a sensor arranged in the water outlet pipe 2; the display component 7 and the sensor are both electrically connected to the controller, the sensor is arranged close to the control valve 4, and the sensor is used to detect whether there is liquid in the water outlet pipe 2; the display component 7 is arranged on the shell 6, and is used to display display information, and the display information is used to display whether there is liquid in the water outlet pipe 2. By arranging the controller, the display component 7 and the sensor to cooperate with each other, it is possible to monitor whether there is liquid in the water outlet pipe 2. When there is liquid in the water outlet pipe 2, the controller controls the display component 7 to display information to prompt the user that there is liquid in the water outlet pipe 2, thereby avoiding the liquid retained in the water outlet pipe 2 from contacting with the air to breed bacteria, avoiding direct drinking from causing harm to the user's body, and also avoiding the liquid retained in the water outlet pipe 2 from having too high a temperature and scalding the user, thereby increasing the safety of the water outlet when in use.

[0069] Specifically, the sensor is a liquid level sensor, which is arranged at one end of the water outlet pipe 2 close to the shell 6, and is used to obtain liquid information in the water outlet pipe 2. When there is liquid in the water outlet pipe 2, the sensor sends liquid existence information to the controller. When there is no liquid in the water outlet pipe 2, the sensor sends liquid non-existence information to the controller; the controller controls the display component 7 to display corresponding display information according to the corresponding information, and the display information includes two types of information: the absence of liquid and the presence of liquid.

[0070] Specifically, the display information includes text information, video information or audio information.

[0071] Specifically, the water outlet also includes a fixed end, which is used to be fixedly connected to the surface to be installed. The fixed end is a hollow structure, and a thread is provided on the outer side of the fixed end so that the fixed end can be fixedly connected to the surface to be installed; the fixed end is arranged opposite to the first connecting hole, and the fixed end and the water outlet pipe 2 are arranged opposite to each other on both sides of the shell 6; a flat washer and a parallel ring are sequentially sleeved on the outer side of the fixed end to achieve the fastening effect of the fixed end and the surface to be installed.
