Description

Technical Field

[0001] The present invention relates to the technical field of water outlet equipment, and in particular to a water outlet device and a water purification system. Background Art

[0002] The water outlet device includes a water outlet and a water outlet pipe connected to the water outlet. A heating element is arranged on the water outlet pipe. The heating element is controlled to be turned on or off to meet the user's needs for hot water or normal temperature water. However, some water will remain in the water outlet after each water is taken. When the water is taken next time, the residual water flowing out of the water outlet will not meet the user's water temperature requirements. When hot water and normal temperature water are taken alternately, the water remaining in the water outlet will not meet the user's water demand due to too high or too low temperature. Even when a small amount of normal temperature water is taken after hot water, the hot water remaining in the water outlet will cause the temperature of the normal temperature water taken to be too high, causing scalding, posing a safety hazard. Summary of the invention

[0003] In view of this, the present invention provides a water outlet device and a water purification system to solve the problem that the residual water flowing out of the water outlet of the existing water outlet device when the water is drawn next time does not meet the user's water drawing temperature requirement, and when hot water and normal temperature water are taken alternately, the residual water in the water outlet will not meet the user's water drawing demand due to too high or too low temperature, and even the hot water residual in the water outlet will cause the temperature of the normal temperature water taken to be too high and cause scalding, posing a safety hazard.

[0004] A first aspect of the present invention provides a water outlet device, comprising a water outlet nozzle, a water outlet pipe and a reflux module, wherein the water outlet nozzle has a water outlet cavity, the water outlet end of the water outlet pipe is connected to the water outlet cavity, the water outlet pipe is used to transport hot water or normal temperature water to the water outlet cavity, and the reflux module is used to return water in the water outlet cavity that has not reached a preset temperature value to the water inlet end of the water outlet pipe.

[0005] Beneficial effect: The water outlet device of the present application is provided with a reflux module. When the water in the water outlet chamber of the water outlet nozzle does not reach the preset temperature value, the reflux module can reflux the water in the water outlet chamber that has not reached the preset temperature value to the water inlet end of the water outlet pipe, until the water in the water outlet chamber of the water outlet nozzle reaches the preset temperature value before flowing out for the user to take, thereby ensuring that the water outlet temperature of the water outlet nozzle always meets the user's water demand.

[0006] In some embodiments, the reflux module includes a reflux pipeline and a control valve, one end of the reflux pipeline is connected to the water outlet chamber, and the other end of the reflux pipeline is connected to the water inlet end of the water outlet pipeline. The control valve is arranged on the reflux pipeline, and the control valve is used to open the reflux pipeline so that the water in the water outlet chamber that has not reached the preset temperature value can flow back to the water inlet end of the water outlet pipeline through the reflux pipeline.

[0007] Beneficial effect: When the water in the water outlet chamber does not reach the preset temperature value, the control valve conducts the reflux pipeline, and the water in the water outlet chamber that does not reach the preset temperature value flows back through the reflux pipeline to the water inlet end of the water outlet pipeline, realizing water reflux.

[0008] In some embodiments, the water outlet device also includes a temperature sensor, which is disposed at the water outlet nozzle. Based on the temperature sensor detecting that the water in the water outlet chamber has not reached a preset temperature value, the control valve is controlled to open the return pipeline.

[0009] Beneficial effect: The temperature sensor can detect the temperature of the water in the water outlet nozzle. When the temperature sensor detects that the water in the water outlet chamber does not reach the preset temperature value, the control valve is controlled to open the reflux pipeline to allow the water in the water outlet chamber that does not reach the preset temperature value to reflux through the reflux pipeline.

[0010] In some embodiments, based on the temperature sensor detecting that the water in the water outlet chamber has reached a preset temperature value, the control valve is controlled to close the return pipeline.

[0011] Beneficial effect: When the temperature sensor detects that the water in the water outlet cavity has reached a preset temperature value, the control valve is controlled to close the return pipeline to prevent the water in the water outlet cavity of the water outlet nozzle that has reached the preset temperature value from flowing out through the return pipeline.

[0012] In some embodiments, the connection between the return pipe and the water outlet cavity is located below the connection between the water outlet end and the water outlet cavity.

[0013] Beneficial effect: By locating the connection between the reflux pipeline and the water outlet chamber below the connection between the water outlet end and the water outlet chamber, the reflux pipeline can also reflux water with a lower water level in the water outlet chamber, making it easier for the water outlet pipeline to deliver water to the water outlet chamber.

[0014] In some embodiments, the water outlet device also includes a heating element, which is arranged between the water inlet end and the water outlet end of the water outlet pipe. The heating element is operated when the user takes hot water, and is turned off when the user takes normal temperature water.

[0015] Beneficial effect: The heating element can heat the water flowing through it. When the user uses hot water, the water flows from the water inlet end of the water outlet pipe to the water outlet end, and the water flows through the heating element to be heated. When the user uses normal temperature water, the heating element is in the closed state, and the normal temperature water flows from the water inlet end of the water outlet pipe to the water outlet end and flows into the water outlet nozzle.

[0016] In some embodiments, the water outlet device also includes a water pump, and the water pump is arranged in the water outlet pipeline.

[0017] Beneficial effect: The water pump can provide pressure for the flow of water, so that the water flows from the water inlet end of the water outlet pipe to the water outlet end and finally flows into the water outlet cavity of the water outlet nozzle.

[0018] In some embodiments, the water outlet device further includes a water tank, and the water tank is connected to the water inlet end of the water outlet pipeline.

[0019] Beneficial effect: The water tank can store a certain amount of domestic water. When water is needed, water flows from the water tank into the water inlet end of the water outlet pipe, and flows from the water inlet end to the water outlet end and into the water outlet cavity of the water outlet nozzle.

[0020] In some embodiments, the water outlet is further provided with a water receiving port, and the water receiving port is connected to the water outlet cavity.

[0021] Beneficial effect: The water inlet provided at the water outlet can facilitate users to take water, and the water in the water outlet cavity that reaches the preset temperature value flows out through the water inlet for users to use.

[0022] A second aspect of the present invention provides a water purification system, comprising a water purifier and a water outlet device of the present invention, wherein the water purifier is used to produce pure water, and a water outlet pipeline of the water outlet device is connected to the water purifier.

[0023] Beneficial effect: Since the water purification system of the present invention includes the water outlet device of the present invention, the water purification system has the same technical effect as the water outlet device, which will not be repeated here.

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0042] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0043] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0045] Combine the following Figures 1 to 8 , describing an embodiment of the present invention.

[0046] like Figure 1 and Figure 8 As shown, according to an embodiment of the present invention, on the one hand, a water outlet device is disclosed, including a water outlet nozzle 1, a water outlet pipe 2 and a reflux module 3, wherein the water outlet nozzle 1 has a water outlet cavity 11, a water outlet end 22 of the water outlet pipe 2 is connected to the water outlet cavity 11, the water outlet pipe 2 is used to transport hot water or room temperature water to the water outlet cavity 11, and the reflux module 3 is used to return water in the water outlet cavity 11 that has not reached a preset temperature value to the water inlet end 21 of the water outlet pipe 2.

[0047] The water outlet device of the present application is provided with a reflux module 3. When the water in the water outlet cavity 11 of the water outlet nozzle 1 does not reach the preset temperature value, the reflux module 3 can reflux the water in the water outlet cavity 11 that does not reach the preset temperature value to the water inlet end 21 of the water outlet pipe 2, until the water in the water outlet cavity 11 of the water outlet nozzle 1 reaches the preset temperature value before flowing out for the user to take, thereby ensuring that the water outlet temperature of the water outlet nozzle 1 always meets the user's water demand.

[0048] It can be understood that when a user needs to take hot water, the water outlet pipe 2 is used to transport hot water to the water outlet chamber 11. The temperature of the water remaining in the water outlet chamber 11 is relatively low (lower than the preset temperature value). At this time, the water with a relatively low temperature can be refluxed to the water inlet end 21 of the water outlet pipe 2 through the reflux module 3 until the temperature of the water in the water outlet chamber 11 reaches the preset temperature value and flows out for use by the user, thereby ensuring the water intake temperature of the user;

[0049] When the user switches from taking hot water to taking normal temperature water, the water outlet pipe 2 is used to transport normal temperature water to the water outlet chamber 11. Since there is still hot water remaining in the water outlet chamber 11 and the hot water temperature is relatively high (higher than the preset temperature value), the remaining hot water can be refluxed to the water inlet end 21 of the water outlet pipe 2 through the reflux module 3 at this time, so as to avoid scalding the user by the hot water and improve the safety of use.

[0050] It should be noted that the preset temperature value is specifically related to the user's water intake temperature. When the user takes water at different temperatures, the preset temperature value will also change.

[0051] For example, when a user uses boiling water to make tea, the preset temperature value is 98°C to 100°C.

[0052] For another example, when a user uses warm water to make milk powder, the preset temperature value is 45°C to 55°C.

[0053] When the user uses normal temperature water, the preset temperature value is equal to the ambient temperature. For example, the preset temperature value in summer can be 20°C to 40°C, and the preset temperature value in winter can be 0°C to 20°C.

[0054] like Figure 5 and Figure 6 As shown, the water outlet cavity 11 is a cavity formed inside the water outlet nozzle 1, which can store a certain amount of water. The water first flows into the water outlet cavity 11 to achieve confluence buffering, and then flows to the outside through the water outlet cavity 11 for users to take.

[0055] The shape and size of the water outlet cavity 11 are related to the shape and size of the water outlet nozzle 1 and can be specifically set according to actual needs.

[0056] For example, when the shape of the water outlet 1 is satisfactory and the size is large, the water outlet cavity 11 can be appropriately set larger to store more water;

[0057] For another example, when the shape and size of the water outlet nozzle 1 are small, the water outlet cavity 11 can be appropriately set to be smaller.

[0058] like Figure 8 As shown, in some embodiments, the reflux module 3 includes a reflux pipeline 31 and a control valve 32, wherein one end of the reflux pipeline 31 is connected to the water outlet chamber 11, and the other end of the reflux pipeline 31 is connected to the water inlet end 21 of the water outlet pipeline 2, and the control valve 32 is arranged on the reflux pipeline 31, and the control valve 32 is used to conduct the reflux pipeline 31 so that the water in the water outlet chamber 11 that has not reached the preset temperature value can flow back to the water inlet end 21 of the water outlet pipeline 2 through the reflux pipeline 31.

[0059] When the water in the water outlet chamber 11 does not reach the preset temperature value, the control valve 32 conducts the reflux pipe 31, and the water in the water outlet chamber 11 that does not reach the preset temperature value flows back through the reflux pipe 31 to the water inlet end 21 of the water outlet pipe 2, thereby realizing water reflux.

[0060] Of course, when the water in the water outlet chamber 11 reaches a preset temperature, the control valve 32 closes the return pipe 31 to prevent the water in the water outlet chamber 11 that has reached the preset temperature from flowing out through the return pipe 31 .

[0061] like Figure 2 and Figure 3As shown, in some embodiments, the water outlet device also includes a temperature sensor 5, which is arranged at the water outlet nozzle 1. Based on the temperature sensor 5 detecting that the water in the water outlet chamber 11 has not reached a preset temperature value, the control valve 32 is controlled to open the return pipe 31.

[0062] The temperature sensor 5 can detect the temperature of the water in the water outlet nozzle 1. When the temperature sensor 5 detects that the water in the water outlet chamber 11 does not reach the preset temperature value, the control valve 32 is controlled to open the return pipe 31 so that the water in the water outlet chamber 11 that does not reach the preset temperature value can reflux through the return pipe 31.

[0063] In some embodiments, based on the temperature sensor 5 detecting that the water in the water outlet chamber 11 reaches a preset temperature value, the control valve 32 is controlled to close the return pipeline 31 .

[0064] When the temperature sensor 5 detects that the water in the water outlet cavity 11 has reached a preset temperature value, the control valve 32 is controlled to close the return pipe 31 to prevent the water in the water outlet cavity 11 of the water outlet nozzle 1 that has reached the preset temperature value from flowing out through the return pipe 31 .

[0065] In some embodiments, the connection between the return pipe 31 and the water outlet chamber 11 is located below the connection between the water outlet end 22 and the water outlet chamber 11 .

[0066] By locating the connection between the reflux pipe 31 and the water outlet chamber 11 below the connection between the water outlet end 22 and the water outlet chamber 11 , the reflux pipe 31 can also reflux water with a lower water level in the water outlet chamber 11 , thereby facilitating the water outlet pipe 2 to deliver water to the water outlet chamber 11 .

[0067] Specifically, the water outlet 1 has a first interface 12 and a second interface 13, wherein the first interface 12 and the second interface 13 are both connected to the water outlet chamber 11, the first interface 12 is located above the second interface 13, the first interface 12 is connected to the water outlet end 22 of the water outlet pipe 2, and the second interface 13 is connected to the return pipe 31.

[0068] like Figure 1 and Figure 7 As shown, in some embodiments, the water outlet device also includes a heating element 4, which is arranged between the water inlet end 21 and the water outlet end 22 of the water outlet pipe 2. The heating element 4 operates when the user takes hot water, and is turned off when the user takes normal temperature water.

[0069] The heating element 4 can heat the water flowing through it. When the user uses hot water, the water flows from the water inlet end 21 of the water outlet pipe 2 to the water outlet end 22, and the water flows through the heating element 4 to be heated. When the user uses normal temperature water, the heating element 4 is in a closed state, and the normal temperature water flows from the water inlet end 21 of the water outlet pipe 2 to the water outlet end 22 and flows into the water outlet 1.

[0070] Specifically, the heating element 4 may be an instant heating tube, but is not limited thereto.

[0071] The heating element 4 includes an inlet 41 and an outlet 42, wherein the inlet 41 is connected to the water inlet end 21 of the water outlet pipe 2, and the outlet 42 is connected to the water outlet end 22 of the water outlet pipe 2. Water flows from the water inlet end 21 of the water outlet pipe 2 through the inlet 41 into the heating element 4, and flows to the water outlet end 22 of the water outlet pipe 2 through the outlet 42 of the heating element 4.

[0072] To ensure the sealing of the connection, a sealed connection is adopted between the inlet 41 of the heating element 4 and the water inlet end 21 of the water outlet pipe 2, and / or a sealed connection is adopted between the outlet 42 of the heating element 4 and the water outlet end 22 of the water outlet pipe 2.

[0073] The above arrangement can prevent water from leaking from the connection between the inlet 41 of the heating element 4 and the water inlet end 21 of the water outlet pipe 2, and / or the connection between the outlet 42 of the heating element 4 and the water outlet end 22 of the water outlet pipe 2, thereby ensuring the sealing of the connection between the structures.

[0074] Specifically, a sealing structure may be provided between the inlet 41 of the heating element 4 and the water inlet end 21 of the water outlet pipe 2, and / or between the outlet 42 of the heating element 4 and the water outlet end 22 of the water outlet pipe 2, and the sealing structure may be used to fill and seal the gap between the inlet 41 of the heating element 4 and the water inlet end 21 of the water outlet pipe 2, and / or the gap between the outlet 42 of the heating element 4 and the water outlet end 22 of the water outlet pipe 2.

[0075] More specifically, the sealing structure may be a sealing ring, such as an O-ring, a U-ring or a special-shaped ring, etc., which may be configured as required and is not limited in this embodiment.

[0076] In the present application, the sealing structure is an O-ring, and O-rings are arranged between the inlet 41 of the heating element 4 and the water inlet end 21 of the water outlet pipe 2, and between the outlet 42 of the heating element 4 and the water outlet end 22 of the water outlet pipe 2, so as to ensure the connection sealing between the inlet 41 of the heating element 4 and the water inlet end 21 of the water outlet pipe 2, and between the outlet 42 of the heating element 4 and the water outlet end 22 of the water outlet pipe 2.

[0077] In some embodiments, the water outlet device further includes a water pump 6 , which is disposed in the water outlet pipeline 2 .

[0078] The water pump 6 can provide pressure for the flow of water, so that the water flows from the water inlet end 21 of the water outlet pipe 2 to the water outlet end 22 and finally flows into the water outlet cavity 11 of the water outlet nozzle 1 .

[0079] Exemplarily, the water pump 6 may be a self-priming pump, a vacuum pump, etc., which may be selected according to actual needs, and this embodiment does not limit it.

[0080] Since the water pump 6 is a prior art, it will not be described in detail in this embodiment.

[0081] In some embodiments, the water outlet device further includes a water tank 7 , and the water tank 7 is connected to the water inlet end 21 of the water outlet pipeline 2 .

[0082] The water tank 7 can store a certain amount of domestic water. When water is needed, water flows from the water tank 7 into the water inlet end 21 of the water outlet pipe 2, and flows from the water inlet end 21 to the water outlet end 22 and into the water outlet cavity 11 of the water outlet nozzle 1.

[0083] The shape of the water tank 7 can be circular, elliptical or geometric, etc., and can be set according to specific needs, and this embodiment does not limit it.

[0084] The size of the water tank 7 can be set according to the volume of the water outlet device. For example, when the volume of the water outlet device is large and there is more space left inside, the water tank 7 can be set larger to store more water. When the volume of the water outlet device is small and there is less space left inside, the water tank 7 can be set smaller to reduce space occupancy.

[0085] As for the specific setting position, illustratively, the water tank 7 is set at the upstream, the water pump 6 is set upstream of the heating element 4, and the connection between the return pipe 31 and the water inlet end 21 of the outlet pipe 2 is located upstream of the water pump 6, so that the return water can flow to the heating element 4 through the water pump 6.

[0086] In some embodiments, the water outlet 1 is further provided with a water receiving port 15 , and the water receiving port 15 is communicated with the water outlet cavity 11 .

[0087] The water outlet 1 is provided with a water inlet 15 , which can facilitate users to take water. The water in the water outlet cavity 11 that reaches a preset temperature value flows out through the water inlet 15 for use by users.

[0088] It can be understood that the water outlet 1 is provided with a water receiving valve, and the water receiving port 15 can be opened or closed by controlling the water receiving valve. Specifically, when the water in the water outlet chamber 11 has reached a preset temperature value, the water receiving valve is opened to open the water receiving port 15, so that the water reaching the preset temperature value flows out from the water receiving port 15; when the water in the water outlet chamber 11 does not reach the preset temperature value, the water receiving valve is closed to close the water receiving port 15, so as to prevent the water that does not reach the preset temperature value from flowing out from the water receiving port 15.

[0089] Preferably, the water inlet 15 is disposed at the bottom of the water outlet chamber 11 , so that the water in the water outlet chamber 11 can flow toward the water inlet 15 by its own weight.

[0090] like Figure 5 or Figure 6As shown, in addition, a mounting position 14 is provided on the water outlet 1, and the mounting position 14 is used to install the temperature sensor 5, so as to achieve the installation and fixation of the temperature sensor 5 and ensure the stability of the temperature sensor 5 in use.

[0091] At the same time, in order to facilitate the installation and connection of the water outlet 1, the water outlet 1 is also provided with a mounting ear 16. The mounting ear 16 facilitates the installation and fixation of the water outlet 1 and other structures to ensure the structural installation stability of the water outlet 1.

[0092] In terms of the number of installations, two installation ears 16 can be provided, and the two installation ears 16 are arranged on opposite sides of the water outlet 1, so that the opposite sides of the water outlet 1 are connected and fixed to other structures, thereby enhancing the structural connection reliability of the water outlet 1.

[0093] Of course, the number and positions of the mounting ears 16 can also be adjusted as needed and are not limited to the settings in this embodiment.

[0094] Specifically, the mounting ears 16 are provided with mounting holes, and the water spout 1 can be fixedly connected to other structures by fasteners such as bolts and screws that fit into the mounting holes and are connected and fixed to other structures.

[0095] In addition, for the convenience of control, the water outlet device of this embodiment also includes a control unit, and the control unit and the temperature sensor 5, the control valve 32 and the water receiving valve are all communicatively connected.

[0096] When the temperature sensor 5 detects that the temperature of the water at the water outlet 1 is lower than the preset temperature value, the control unit controls the control valve 32 to open to conduct the return pipe 31. At this time, the water receiving valve remains in a closed state. When the temperature sensor 5 detects that the temperature of the water at the water outlet 1 reaches the preset temperature value, the control unit controls the control valve 32 to close to close the return pipe 31. At the same time, the control valve 32 controls the water receiving valve to open, so that the water in the water outlet chamber 11 flows out through the water receiving port 15 for the user to take.

[0097] In order to facilitate the understanding of the water outlet device of this embodiment, the following is a Figure 1 To Attachment Figure 8 The usage process is introduced as follows:

[0098] When the user needs to take hot water, the heating element 4 is in the open state, water flows out of the water tank 7 and flows into the water inlet end 21 of the water outlet pipe 2, flows into the heating element 4 through the water inlet end 21 and is heated into hot water, and the hot water flows from the heating element 4 to the water outlet end 22 of the water outlet pipe 2, and flows into the water outlet cavity 11 of the water outlet nozzle 1 through the water outlet end 22;

[0099] The temperature sensor 5 detects the temperature of the water in the water outlet chamber 11. When it is detected that the temperature of the water in the water outlet chamber 11 is lower than the preset temperature value, the control unit controls the control valve 32 to open to conduct the reflux pipeline 31. The water in the water outlet chamber 11 flows back to the water inlet end 21 of the water outlet pipeline 2 through the reflux pipeline 31, and mixes with the water in the water inlet end 21 and flows to the heating element 4 together to achieve reheating. When the temperature sensor 5 detects that the temperature of the water in the water outlet chamber 11 reaches the preset temperature value, the control unit controls the control valve 32 to close to close the reflux pipeline 31. At the same time, the control unit controls the water inlet valve to open to conduct the water inlet 15, so that the hot water with the preset temperature value in the water outlet chamber 11 flows out through the water inlet 15 for the user to take.

[0100] When the user needs to take normal temperature water, the heating element 4 is in the closed state, and water flows out of the water tank 7 and flows into the water inlet end 21 of the water outlet pipe 2, flows through the water inlet end 21, the heating element 4 and the water outlet end 22, and then flows into the water outlet cavity 11;

[0101] When there is residual hot water in the water outlet chamber 11 and the temperature sensor 5 detects that the temperature of the water in the water outlet chamber 11 is higher than the preset temperature value, the control unit controls the control valve 32 to open to connect the reflux pipe 31, and the residual hot water in the water outlet chamber 11 flows through the reflux pipe 31 and flows back to the water inlet end 21 of the water outlet pipe 2, and mixes with the normal temperature water in the water inlet end 21 and flows together to the water outlet 1; when the temperature sensor 5 detects that the temperature of the water in the water outlet chamber 11 reaches the preset temperature value, the control unit controls the control valve 32 to close to close the reflux pipe 31, and at the same time the control unit controls the water inlet valve to open to connect the water inlet 15, so that the normal temperature water in the water outlet chamber 11 flows out through the water inlet 15 for the user to take.

[0102] According to an embodiment of the present invention, on the other hand, a water purification system is disclosed, including a water purifier and a water outlet device of the present invention, wherein the water purifier is used to produce pure water, and a water outlet pipeline 2 of the water outlet device is connected to the water purifier.

[0103] Since the water purification system of the present invention includes the water outlet device of the present invention, the water purification system has the same technical effect as the water outlet device, which will not be described in detail here.

[0104] It can be understood that the water outlet pipe 2 of the water outlet device is connected to the water purifier, and the pure water taken out by the water purifier flows to the water outlet nozzle 1 through the water outlet pipe 2 for the user to take.
