The terms used in the description of the present utility model in this article are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0026] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] As Figure 3 、 Figure 4 、 Figure 5A drip-proof water outlet nozzle 100 as shown includes a box part 11, a water outlet part 13 and a water inlet part 14. The box part 11 is connected to the water outlet part 13 and the water inlet part 14 respectively. The water outlet part 13 is provided with a water outlet channel 02, and the water inlet part 14 is provided with a water inlet channel 03. A chamber 01 is arranged inside the box part 11. Water flows into the chamber 01 through the water inlet channel 03 and then flows out through the water outlet channel 02. The chamber 01 has a preset residual liquid level 07, which refers to the liquid level of the water remaining inside the drip-proof water outlet nozzle 100 after the water discharge ends; one end of the water outlet channel 02 close to the chamber 01 protrudes from the inner wall of the chamber 01 to form an annular protrusion 131, and the annular protrusion 131 protrudes above the residual liquid level 07. In this way, the inlet of the water outlet channel 02 will be higher than the residual liquid level 07. When the water discharge ends, the water remaining inside the chamber 01 will not easily enter the water outlet channel 02, thus achieving the effect of preventing dripping.

[0028] The technical details of each component will be introduced one by one below.

[0029] In some embodiments, as Figure 5 shown, the height by which the above-mentioned annular protrusion 131 protrudes above the residual liquid level 07 is not less than 0.5 mm and not more than 15 mm.

[0030] In practical applications, when the height by which the annular protrusion 131 protrudes above the residual liquid level 07 is within the above range, on the one hand, it will not affect the anti-dripping effect, and on the other hand, it will not affect the water discharge efficiency of the drip-proof water outlet nozzle 100. When the height by which the annular protrusion 131 protrudes above the residual liquid level 07 is too low, under the action of external vibration, the water remaining inside the chamber 01 will fluctuate. When fluctuating, the maximum height of the liquid level of the water remaining inside the chamber 01 will slightly increase and exceed the residual liquid level 07. When the height by which the annular protrusion 131 protrudes above the residual liquid level 07 is too low, the water remaining inside the chamber 01 will cross the upper edge of the annular protrusion 131 under the fluctuation and enter the water outlet channel 02, resulting in dripping; when the height by which the annular protrusion 131 protrudes above the residual liquid level 07 is too high, on the one hand, it will increase the thickness of the drip-proof water outlet nozzle 100, making it inconvenient for assembly and miniaturization; on the other hand, when discharging water, the amount of water required to submerge the upper edge of the annular protrusion 131 inside the chamber 01 increases, resulting in an extended water discharge time of the drip-proof water outlet nozzle 100 and causing a bad user experience.

[0031] In some embodiments, as Figure 5As shown, the top of the above-mentioned chamber 01 is higher than the annular protrusion 131, and the residual liquid level surface 07 is flush with the highest liquid level of the water inlet channel 03. The highest liquid level of the water inlet channel 03 refers to: after the water inlet stops, the highest liquid level of the water (i.e., the residual water) retained in the water inlet channel 03. The water outlet channel 02 is longitudinally arranged at the front end of the drip-proof water outlet nozzle 100, and the water inlet channel 03 is transversely arranged or arranged in a "7" shape. The water inlet of the water inlet channel 03 is generally located below the drip-proof water outlet nozzle 100, that is, the water inlet is lower than the water inlet channel 03 and the water outlet channel 02. When water enters from the water inlet, the water enters the chamber 01 through the water inlet channel 03 and overflows the annular protrusion 131 and is discharged from the water outlet channel 02. After the water inlet stops, the water inside the chamber 01 and the water inlet channel 03 is residual water. Since when the water inlet stops, part of the water can flow back or be sucked back through the water inlet, the liquid level of the residual water in the water inlet channel 03 and the chamber 01 is lower than the annular protrusion 131 and is maintained at the residual liquid level surface 07.

[0032] In practical applications, when water flows through the water inlet channel 03 into the chamber 01, the highest liquid level surface of the water inlet channel 03 being flush with the residual liquid level surface 07 can ensure that after the water discharge switch is closed, since the chamber 01 and the water inlet channel 03 are in a communicating state, the liquid level inside the chamber 01 will not be higher than the residual liquid level surface 07 due to the liquid level inside the water inlet channel 03, making the anti-drip effect of the drip-proof water outlet nozzle 100 more stable.

[0033] Furthermore, the distance between the above-mentioned annular protrusion 131 and the top of the chamber 01 is greater than 1 mm but less than 7 mm. If the distance between the annular protrusion 131 and the top of the chamber 01 is less than 1 mm, when discharging water, the water discharge volume of the water outlet channel 02 will be affected due to the too small distance between the water inlet of the water inlet channel 03 and the inner wall of the chamber 01. If the distance between the annular protrusion 131 and the top of the chamber 01 is too large, the thickness of the drip-proof water outlet nozzle 100 will increase, which is not conducive to the assembly and miniaturization of the drip-proof water outlet nozzle 100. In addition to the above effects, if the distance between the annular protrusion 131 and the top of the chamber 01 is too large, many redundant spaces will be generated inside the chamber 01, thus causing waste in structure and space.

[0034] In some embodiments, such as Figure 4 、 Figure 5As shown, a water blocking member 12 is provided inside the above-mentioned chamber 01. The water blocking member 12 is connected to the inner wall of the chamber 01 and is disposed opposite to the water inlet passage 03 to block the buffer water flow. The water inside the water inlet passage 03 is blocked by the water blocking member 12 after flowing out of the water inlet passage 03. The blocked water flow can flow into the chamber 01 from both sides of the water blocking member 12 (correspondingly, when the residual water inside the chamber 01 flows back or is sucked back into the water inlet passage 03, the water flow can flow back or be sucked back into the water inlet passage 03 from both sides of the water blocking member 12). In this way, without affecting the flow rate at the outlet of the water inlet passage 03, the flow rate of the water flow in the water inlet passage 03 entering the chamber 01 can be slowed down, thereby reducing the impact effect of the water flow inside the chamber 01; at the same time, the water blocking member 12 can also buffer the fluctuation of the liquid level inside the chamber 01, making the liquid level inside the chamber 01 more likely to return to calm, which is beneficial to improving the water outlet effect of the anti-drip water outlet nozzle 100.

[0035] Further, as Figure 4 、 Figure 5 shown, the above-mentioned water blocking member 12 includes a blocking portion 121 and a diagonal brace 122. The blocking portion 121 is disposed on the inner wall of the chamber 01, and the diagonal brace 122 is respectively connected to the blocking portion 121 and the inner wall of the chamber 01 to reinforce the blocking portion 121. Through the above design, the water blocking member 12 can be made more stable as a whole.

[0036] In some embodiments, as Figure 4 、 Figure 5 shown, along the protruding direction of the annular protrusion 131, the water blocking member 12 protrudes from the residual liquid level surface 07. With such a design, the waterproof member can reduce the fluctuation of the liquid level inside the chamber 01, and at the same time can also improve the buffering effect of the water blocking member 12 on the water flow entering the chamber 01.

[0037] In some embodiments, as Figure 5 shown, the above-mentioned box portion 11 includes a box body 111 and a cover body 112, and the cover body 112 is hermetically sealed to the box body 111. Since some important structures are provided inside the box portion 11, through the above split design, the processing and production of the anti-drip water outlet nozzle 100 can be facilitated, and the production difficulty of the anti-drip water outlet nozzle 100 is greatly reduced.

[0038] Further, a sealing ring is also provided between the box body 111 and the cover body 112. When the box body 111 and the cover body 112 are mutually covered and welded, there may be minute gaps, which may have an adverse effect on the sealing performance of the connection structure between the box body 111 and the cover body 112; the sealing ring can effectively block the minute gaps existing between the box body 111 and the cover body 112, thereby effectively ensuring the sealing performance of the connection structure between the box body 111 and the cover body 112. In practical applications, through the above design of the sealing ring, the liquid inside the chamber 01 will not flow out through the gaps between the box body 111 and the cover body 112.

[0039] It is understandable that the above-mentioned box body 111 and cover body 112 are usually made of plastic material and can be ultrasonically welded together after being covered with each other. The ultrasonic welding method will not generate high temperature, and will not have a great impact on the material properties of the box body 111 and the cover body 112 after welding, nor will it release some substances harmful to human health, thereby preventing the water-dripping faucet 100 from polluting the water when discharging water.

[0040] In some embodiments, such as Figure 3 、 Figure 4 、 Figure 5 As shown, the water outlet part 13 is arranged longitudinally and connected to the lower side of the box part 11, and the water inlet channel 03 is arranged horizontally and communicated with one side of the chamber 01. Through the above design, the water flow directions of the water outlet channel 02 and the water inlet channel 03 are perpendicular to each other in space, which is beneficial to preventing the water remaining inside the chamber 01 from entering the water outlet channel 02 and dripping.

[0041] Such as Figure 1 、 Figure 2 As shown, a water-dripping prevention faucet provided by the present application includes a main body 200 and the above-mentioned water-dripping prevention water outlet nozzle 100. An assembly cavity 04 is provided inside the main body 200. An inlet 05 and an outlet 06 are provided on the inner wall of the assembly cavity 04. At least part of the water-dripping prevention water outlet nozzle 100 is assembled in the assembly cavity 04. The inlet 05 is used to communicate with the water inlet channel 03, and the outlet 06 communicates with the water outlet channel 02. The water outlet channel 02 communicates with the external environment through the outlet 06. After the water-dripping prevention faucet is connected to an external water source, the external water source flows out through the inlet 05 and enters the above-mentioned water-dripping prevention water outlet nozzle 100, then flows out of the water-dripping prevention water outlet nozzle 100 through the water outlet channel 02, and flows out from the outlet 06. Under the action of the above-mentioned water-dripping prevention water outlet nozzle 100, the water-dripping prevention faucet can reduce the dripping of the remaining water after the water discharge is finished, thereby improving the user experience when using the water-dripping prevention faucet.

[0042] In some embodiments, such as Figure 1 、 Figure 2 As shown, the side of the water outlet channel 02 close to the outlet 06 protrudes from the outlet 06. In practical applications, after the above-mentioned water-dripping prevention water outlet nozzle 100 is assembled in the assembly cavity 04 inside the main body 200, a gap 08 will be formed between the water outlet part 13 and the outlet 06. When the water outlet channel 02 discharges water, part of the water flow will enter the inside of the assembly cavity 04 through the gap 08 and cause siltation. After a long time, the silted water will pollute the discharged water, thereby affecting the water use safety. Through the above design, the side of the water outlet channel 02 close to the outlet 06 protrudes from the outlet 06, so that a distance is formed between the outlet end of the water outlet channel 02 and the outlet 06, thereby effectively avoiding the water flow entering the inside of the assembly cavity 04 through the gap 08 during water discharge and generating siltation, ensuring the water use safety.

[0043] A water purifier provided by the present application includes the above anti-drip faucet.
