Description
TECHNICAL FIELD
[0001] The utility model relates to water purification technical field, especially a water outlet nozzle and water purifier. BACKGROUND
[0002] With the gradual popularization of water purifier in modern society and the iterative development of water purifier itself, most of the high-end water purifiers in the market are equipped with sterilization devices. However, due to the limitations brought by the structural characteristics of the sterilization device itself, the sterilization device in the prior art is arranged at a position away from the discharge port at the end of the fluid flow path. In the foregoing case, the fluid sterilized by the sterilization device will still breed bacteria during the process of passing to the discharge port, resulting in a large number of bacteria in the discharged fluid, which exceeds the standard and is not conducive to the safety of drinking.
[0003] Secondly, most of the water outlet nozzles in the market lack the function of stabilizing the flow of fluid leaving the discharge port. In the absence of the stabilizing function, the fluid leaving the discharge port may drip on one hand, and may splash on the other hand.
[0004] Therefore, there is a demand in the market for a water outlet nozzle and water purifier that can reduce the bacteria breeding in the sterilized fluid and has the function of stabilizing the flow. SUMMARY
[0005] The technical problem to be solved by the utility model is to reduce the bacteria breeding in the sterilized fluid and stabilize the flow of fluid leaving the discharge port, and to provide a water outlet nozzle and water purifier.
[0006] The utility model solves the above technical problems by the following technical solutions:
[0007] A water outlet nozzle is arranged at the discharge port at the end of the fluid flow path, and the water outlet nozzle further comprises:
[0008] A main channel is arranged between the inlet and the outlet of the water outlet nozzle, and a middle section of the main channel is provided with a partition plate, which divides the main channel into an inlet channel and an outlet channel. A first opening is formed in the inlet channel and communicates with the inlet of the water outlet nozzle. A second opening is formed in the outlet channel and communicates with the outlet of the water outlet nozzle. The first opening and the second opening are connected by a sterilization loop.
[0009] A sterilization part acts on the sterilization loop.
[0010] In the present scheme, the main channel, which is communicatively arranged between the inlet and the outlet of the water outlet nozzle, is divided into two sections by the partition, one of which, which is in communication with the inlet of the water outlet nozzle, is an inlet channel, and the other, which is in communication with the outlet of the water outlet nozzle, is an outlet channel, so that after the fluid enters the main channel from the inlet of the water outlet nozzle, it will impact on the partition and thereby be slowed down, constituting a flow stabilizing effect on the fluid.
[0011] In addition, the inlet channel is provided with a first opening in communication with the inlet of the water outlet nozzle, and the outlet channel is provided with a second opening in communication with the outlet of the water outlet nozzle, and the first opening and the second opening are further in communication through the sterilization loop. Thus, the fluid slowed down by the partition flows from the first opening to the sterilization loop, is sterilized by the sterilization part acting on the sterilization loop, and then flows from the second opening to the outlet channel and finally is discharged from the outlet of the water outlet nozzle, so that the fluid can be further buffered and slowed down in the sterilization loop by flowing through the sterilization loop, further playing a flow stabilizing effect.
[0012] On the other hand, the discharge port is arranged at the end of the fluid flow path by the water outlet nozzle, and the sterilization part in the water outlet nozzle sterilizes the fluid flowing in the sterilization loop, so that the fluid is discharged from the discharge port after passing through the sterilization part, i.e. the path of the fluid to the discharge port is eliminated, thereby avoiding the growth of bacteria in the fluid during the process of passing to the discharge port, ensuring that the total number of bacteria is within the range limited by the standard, and ensuring the safety of drinking.
[0013] Preferably, the first opening is located at one end of the inlet channel towards the partition, and the second opening is located at one end of the outlet channel towards the partition; and / or, the first openings are circumferentially spaced apart in the inlet channel, and the second openings are circumferentially spaced apart in the outlet channel.
[0014] In the present scheme, the first opening is located at one end of the inlet channel towards the partition, so that after the fluid is slowed down by impacting on the partition, it can flow from the first opening to the sterilization loop, saving the process of the fluid being guided to the first opening in the inlet channel, avoiding the turbulence that the fluid itself may generate in the foregoing process, and further optimizing the flow stabilizing effect.
[0015] In addition, the second opening is located at one end of the outlet channel towards the partition, so that after the fluid enters the outlet channel from the second opening, it is naturally guided by gravity to flow to the outlet of the water outlet nozzle, thereby avoiding the turbulence that the fluid may generate when flowing towards the partition against gravity after entering the outlet channel from the second opening, and further optimizing the flow stabilizing effect.
[0016] In another aspect, the first openings are circumferentially spaced in the inlet channel, and the second openings are circumferentially spaced in the outlet channel, so that the fluid can enter the sterilization loop uniformly from the first openings, and the fluid can flow out of the sterilization loop uniformly from the second openings, avoiding the turbulence caused by uneven distribution of the fluid.
[0017] Preferably, the sterilization loop is a ring-shaped chamber surrounding the radial side of the main channel, and a flow guide is arranged in the sterilization loop, which divides the sterilization loop into a first loop chamber and a second loop chamber, and the first loop chamber is spaced between the main channel and the second loop chamber.

[0019] In this scheme, the flow guide divides the ring-shaped sterilization loop into a first loop chamber and a second loop chamber, and one end of the flow guide towards the inlet of the water outlet nozzle is provided with a first communication port, and the other end of the flow guide towards the outlet of the water outlet nozzle is provided with a second communication port, so that the fluid can first enter the first loop chamber from the first opening, and then further flow into the second loop chamber from the first communication port and the second communication port, and then be buffered again, thereby optimizing the flow stabilization effect.
[0020] Preferably, a sealing ring is arranged in the first loop chamber, and the sealing ring is arranged at the position of the main channel spaced by the first opening and the second opening, and the sealing ring is tightly abutted between the inner surface of the flow guide and the outer surface of the main channel.
[0021] In this scheme, the sealing ring is arranged at the position of the main channel spaced by the first opening and the second opening, and the sealing ring is tightly abutted between the inner surface of the flow guide and the outer surface of the main channel, so that the fluid entering the first loop chamber from the first opening is forced to pass through the first communication port, and the fluid entering the second loop chamber from the first communication port flows through the entire second loop chamber along the length direction of the second loop chamber, and then returns to the first loop chamber from the second communication port, and then enters the outlet channel through the second opening connected to the first loop chamber, and the fluid itself passes through a long path, which helps the fluid itself to be buffered by the long path, thereby optimizing the flow stabilization effect.
[0022] Preferably, the flow guide is made of Teflon material.
[0023] In this scheme, the flow guide is made of Teflon material, which is corrosion-resistant, high-temperature-resistant and has a small friction coefficient, ensuring the service life of the flow guide.
[0024] Preferably, the sterilization part comprises an LED sterilization unit and a light-transmitting plate, and the light-transmitting plate is arranged between the LED sterilization unit and the sterilization loop.
[0025] In the present solution, the LED sterilization unit projects light with sterilization capability to the sterilization loop through the light-transmitting plate, and the LED sterilization unit is not in direct fluid communication with the sterilization loop, thereby avoiding friction or guidance of the sterilization part to the fluid in the sterilization loop in the case of direct fluid communication, and ensuring the stability of the fluid.
[0026] Preferably, the outlet of the water outlet nozzle is provided with a flow stabilizing unit for stabilizing the fluid flowing out of the outlet of the water outlet nozzle.
[0027] In the present solution, the flow stabilizing unit is arranged at the outlet of the water outlet nozzle for guiding the fluid flowing out of the outlet of the water outlet nozzle, thereby optimizing the flow stabilizing effect.
[0028] Preferably, the flow stabilizing unit is a filter screen.
[0029] In the present solution, the flow stabilizing unit is a filter screen, thereby increasing the surface tension of the fluid at the outlet of the water outlet nozzle by the filter screen, and reducing the risk of dripping.
[0030] Preferably, the water outlet nozzle comprises a shell, and the main channel and the sterilization part are located inside the shell.
[0031] In the present solution, the shell protects the main channel and the sterilization part located inside the shell, and also prevents accidental leakage of the fluid from the water outlet nozzle.

[0033] In the present solution, the water purifier is provided with the water outlet nozzle described in any one of the above solutions, thereby reducing the bacteria proliferated in the fluid after sterilization, and being capable of stabilizing the fluid leaving the discharge port.
[0034] On the basis of common knowledge in the art, the above preferred conditions can be combined arbitrarily, thereby obtaining each preferred embodiment of the present application.
[0035] The positive progress effect of the present application is that, in the water outlet nozzle of the present application, the main channel which is communicatively arranged between the inlet and the outlet of the water outlet nozzle is divided into two sections by the partition, one section which is in communication with the inlet of the water outlet nozzle is an inlet channel, and the other section which is in communication with the outlet of the water outlet nozzle is a discharge channel, thereby impacting the partition after the fluid enters the main channel from the inlet of the water outlet nozzle and thereby obtaining deceleration, and constituting a flow stabilizing effect on the fluid.
[0036] In addition, a first opening is formed on the inlet channel and communicates with the inlet of the water outlet nozzle, a second opening is formed on the outlet channel and communicates with the outlet of the water outlet nozzle, and the first opening and the second opening are communicated through the sterilization loop. Thus, the fluid slowed down by the baffle flows from the first opening to the sterilization loop, and after sterilization by the sterilization part of the sterilization loop, flows from the second opening to the outlet channel and is finally discharged from the outlet of the water outlet nozzle, so that the fluid can be further buffered and slowed down in the sterilization loop by flowing through the sterilization loop, and further plays a role of stabilizing the flow.
[0037] On the other hand, the discharge port is arranged at the end of the fluid flow path through the water outlet nozzle, and the sterilization part in the water outlet nozzle sterilizes the fluid flowing in the sterilization loop, so that the fluid is discharged from the discharge port after sterilization by the sterilization part, that is, the path of the fluid to the discharge port is eliminated, so as to avoid the growth of bacteria in the process of the sterilized fluid to the discharge port, ensure that the total number of bacteria is within the range limited by the standard, and ensure the safety of drinking.

[0063] The utility model will be further illustrated by way of examples below, but the utility model is not limited in the scope of the examples.
[0064] As Figures 1-4 shown, the present embodiment provides a water outlet nozzle 1, which is arranged at a discharge port 2 at the end of a fluid flow path, and further comprises:
[0065] a main channel 10, which is arranged between the inlet and the outlet of the water outlet nozzle 1, and a middle section of the main channel 10 is provided with a partition plate 15, which divides the main channel 10 into an inlet channel 21 and an outlet channel 22, the inlet channel 21 is provided with a first opening 31 which is in communication with the inlet of the water outlet nozzle 1, the outlet channel 22 is provided with a second opening 32 which is in communication with the outlet of the water outlet nozzle 1, and the first opening 31 and the second opening 32 are in communication through a sterilization loop 40; and
[0066] a sterilization part 50, which acts on the sterilization loop 40.
[0067] In specific implementation, the main channel 10 arranged in communication between the inlet and the outlet of the water outlet nozzle 1 is divided into two sections by the partition plate 15, one section in communication with the inlet of the water outlet nozzle 1 is the inlet channel 21, and the other section in communication with the outlet of the water outlet nozzle 1 is the outlet channel 22, so that after the fluid enters the main channel 10 from the inlet of the water outlet nozzle 1, the fluid will impact on the partition plate 15 and slow down thereby, constituting a flow stabilizing effect on the fluid.
[0068] In addition, the first opening 31 is arranged on the inlet channel 21 and is communicated with the inlet of the water outlet nozzle 1, the second opening 32 is arranged on the outlet channel 22 and is communicated with the outlet of the water outlet nozzle 1, and the first opening 31 and the second opening 32 are communicated through the sterilization loop 40. Thus, the fluid slowed down by the baffle 15 flows into the sterilization loop 40 through the first opening 31, is sterilized by the sterilization part 50 of the sterilization loop 40, and then flows into the outlet channel 22 through the second opening 32 and is finally discharged from the outlet of the water outlet nozzle 1, so that the fluid is further slowed down and buffered in the sterilization loop 40 during the process of flowing through the sterilization loop 40, and the flow stabilizing effect is further achieved.
[0069] On the other hand, the sterilization part 50 of the water outlet nozzle 1 is arranged at the discharge port 2 at the end of the fluid flow path, and the sterilization part 50 of the water outlet nozzle 1 sterilizes the fluid flowing in the sterilization loop 40, so that the fluid is discharged from the water outlet nozzle 1 through the discharge port 2 after being sterilized by the sterilization part 50, that is, the path of the fluid to the discharge port 2 is eliminated, so as to avoid the growth of bacteria in the fluid during the process of flowing to the discharge port 2, ensure that the total number of bacteria is within the range limited by the standard, and ensure the safety of drinking.
[0070] The baffle 15 in the embodiment has a flat plate structure, so as to provide a relatively simple and easy-to-produce structure. However, those skilled in the art can adjust the structure and shape of the baffle 15 itself, such as arranging a buffering curved surface on the baffle 15 which can play a buffering role and other flow stabilizing structures commonly used in the art, and the embodiment does not limit this.
[0071] In addition, the first opening 31 and the second opening 32 in the embodiment are both circular hole structures, so as to provide a relatively simple and easy-to-produce structure. However, those skilled in the art can adjust the openings in the embodiment according to actual needs, such as replacing the circular hole structure in the embodiment with a square hole structure or an elliptical hole structure, and the embodiment does not limit this.
[0072] As shown in Figures 1-4 the first opening 31 is located on the inlet channel 21 and faces the baffle 15, and the second opening 32 is located on the outlet channel 22 and faces the baffle 15; and the first opening 31 is circumferentially spaced in the inlet channel 21, and the second opening 32 is circumferentially spaced in the outlet channel 22.
[0073] In specific implementation, the first opening 31 is located at one end of the inlet channel 21 towards the partition plate 15, so that the fluid can flow into the sterilization loop 40 from the first opening 31 after impacting on the partition plate 15 and being decelerated thereby, saving the process of guiding the fluid in the inlet channel 21 to the first opening 31 and avoiding the turbulence that the fluid itself can generate in the foregoing process, further optimizing the flow stabilization effect.
[0074] In addition, the second opening 32 is located at one end of the outlet channel 22 towards the partition plate 15, so that the fluid can be naturally guided by gravity to flow to the outlet of the water outlet nozzle 1 after entering the outlet channel 22 from the second opening 32, thereby avoiding the turbulence that the fluid can generate after entering the outlet channel 22 from the second opening 32 against gravity and flowing towards the partition plate 15, further optimizing the flow stabilization effect.
[0075] On the other hand, the first openings 31 are circumferentially spaced in the inlet channel 21, and the second openings 32 are circumferentially spaced in the outlet channel 22, so that the fluid can uniformly enter the sterilization loop 40 from the first openings 31, and the fluid can uniformly flow out of the sterilization loop 40 from the second openings 32, avoiding the turbulence that can be caused by uneven distribution of the fluid.
[0076] As shown in Figures 1-4 , the sterilization loop 40 is a ring-shaped chamber surrounding the radial side of the main channel 10, and the sterilization loop 40 is provided with a flow guide pipe 60, which divides the sterilization loop 40 into a first loop chamber 81 and a second loop chamber 82, and the first loop chamber 81 is spaced between the main channel 10 and the second loop chamber 82;
[0077] The flow guide pipe 60 is provided with a first communication port 71 at one end towards the inlet of the water outlet nozzle 1, and a second communication port 72 at one end towards the outlet of the water outlet nozzle 1, and the first communication port 71 and the second communication port 72 communicate the first loop chamber 81 and the second loop chamber 82.
[0078] In specific implementation, the flow guide pipe 60 divides the ring-shaped sterilization loop 40 into the first loop chamber 81 and the second loop chamber 82, and the flow guide pipe 60 is provided with the first communication port 71 at one end towards the inlet of the water outlet nozzle 1 and the second communication port 72 at one end towards the outlet of the water outlet nozzle 1, so that the fluid can first enter the first loop chamber 81 from the first opening 31, be buffered for the first time in the first loop chamber 81, and then further flow into the second loop chamber 82 from the first communication port 71 and the second communication port 72 and be buffered for the second time, thereby further optimizing the flow stabilization effect.
[0079] As shown in Figures 1-4 , wherein Figure 4The flow path inside is schematically shown by the dashed line and arrow. The first loop chamber 81 is provided with a sealing ring 83, which is arranged on the main channel 10 at a position spaced apart by the first opening 31 and the second opening 32, and sealingly abuts between the inner surface of the flow guide pipe 60 and the outer surface of the main channel 10.
[0080] In a specific implementation, the sealing ring 83 is arranged on the main channel 10 at a position spaced apart by the first opening 31 and the second opening 32, and sealingly abuts between the inner surface of the flow guide pipe 60 and the outer surface of the main channel 10, so that the fluid entering the first loop chamber 81 from the first opening 31 is forced to pass through the first communication port 71, the fluid entering the second loop chamber 82 from the first communication port 71 flows through the entire second loop chamber 82 along the length direction of the second loop chamber 82, and then returns to the first loop chamber 81 from the second communication port 72, and then enters the exhaust channel 22 through the second opening 32 connected to the first loop chamber 81. In this way, the path of the fluid itself is long, which helps the fluid itself to buffer by using a long path, thereby further optimizing the flow stabilizing effect.
[0081] It should be noted that the specific implementation in this embodiment is to use a single flow guide pipe 60, thereby giving a relatively simple and easy-to-produce and install manner. However, those skilled in the art can also conceive to further improve the embodiment by using multiple flow guide pipes 60 nested in layers, so that the fluid path in the sterilization loop 40 is further lengthened and presents a labyrinth shape, which is not limited in the embodiment.
[0082] As shown in Figures 1-4 , the flow guide pipe 60 is made of Teflon material.
[0083] In a specific implementation, the flow guide pipe 60 is made of Teflon material, which is corrosion-resistant, high-temperature-resistant and has a small friction coefficient, ensuring the service life of the flow guide pipe 60. As an alternative implementation, those skilled in the art can also conceive to use other materials with similar properties to replace the Teflon material, which is not limited in the embodiment.
[0084] As shown in Figures 1-4 , the sterilization part 50 includes an LED sterilization unit 501 and a light-transmitting plate 502, which is arranged between the LED sterilization unit 501 and the sterilization loop 40.
[0085] In a specific implementation, the LED sterilization unit 501 projects light with sterilization capability into the sterilization loop 40 through the light-transmitting plate 502. The LED sterilization unit 501 is not in direct fluid communication with the sterilization loop 40, which avoids friction or guidance of the fluid in the sterilization loop 40 by the sterilization unit 50, thereby ensuring the stability of the fluid. As an alternative implementation, those skilled in the art can replace the LED sterilization unit 501 and the light-transmitting plate 502 with other sterilization devices commonly used in the art according to actual needs, such as a silver contact sterilization device or an ultraviolet sterilization device. When replacing the sterilization device, those skilled in the art can adapt the specific structure of the water outlet nozzle 1, which is not limited in the present embodiment.
[0086] As shown in Figures 1-4 , the outlet of the water outlet nozzle 1 is provided with a flow stabilizing unit 90 for stabilizing the fluid flowing out of the outlet of the water outlet nozzle 1.
[0087] In a specific implementation, the flow stabilizing unit 90 is arranged at the outlet of the water outlet nozzle 1 to guide the fluid flowing out of the outlet of the water outlet nozzle 1, thereby optimizing the flow stabilization. The flow stabilizing unit 90 in the present embodiment is a turbine structure, thereby guiding the flowing fluid. As an alternative implementation, those skilled in the art can replace the turbine structure in the present embodiment with other flow stabilizing units 90 commonly used in the art, such as a flow guide plate, which is not limited in the present embodiment.
[0088] Not shown in the figure, the flow stabilizing unit 90 is a filter screen.
[0089] In a specific implementation, the flow stabilizing unit 90 is a filter screen, thereby increasing the surface tension of the fluid at the outlet of the water outlet nozzle 1 by the filter screen, and reducing the risk of dripping.
[0090] As shown in Figures 1-4 , the water outlet nozzle 1 comprises a housing 100, and the main channel 10 and the sterilization unit 50 are located inside the housing 100.
[0091] In a specific implementation, the housing 100 protects the main channel 10 and the sterilization unit 50 located inside it, and also prevents accidental leakage of the fluid from the water outlet nozzle 1. The water outlet nozzle 1 in the present embodiment is installed by thread connection of the housing 100 with the drain 2. As an alternative implementation, those skilled in the art can replace the thread connection in the present embodiment with other installation methods commonly used in the art, such as embedding, which is not limited in the present embodiment.
[0092] The present embodiment also provides a water purifier (not shown in the figure) which further comprises the above-mentioned water outlet nozzle 1.
[0093] In the specific implementation, the water purifier reduces the bacteria growth in the fluid after sterilization by being provided with the water outlet nozzle 1 of any one of the above, and can stabilize the fluid leaving the discharge port 2.
[0094] Although the specific embodiments of the present application are described above, those skilled in the art should understand that this is only an example, the protection scope of the present application is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present application, but these changes and modifications all fall within the protection scope of the present application.
