Description

Technical Field

[0001] The present invention relates to a faucet, in particular to a household anti-splash faucet, belonging to the technical field of household building materials. Background Art

[0002] There are various anti-splash faucets on the market, aiming to reduce water splash and improve the usage efficiency and cleanliness in the kitchen and bathroom. Existing faucets mainly reduce water splash by optimizing water flow control, changing the water outlet mode or adding a buffer structure. Currently, the mainstream technologies include: 1) Aerator faucet: An aerator is installed at the water outlet to mix water flow with air, forming a soft bubble water flow to reduce the impact force. The aerator is generally installed in the end cap of the water outlet pipe, and the end cap is screwed onto the water outlet pipe. As a result, the structural space is small, and it is easy to be blocked (scale and impurities accumulate) after long-term use, affecting the water flow. It is only suitable for low water pressure environments, and splashing may still occur under high water pressure. 2) Shower-type water outlet faucet: Designed after a shower head, the water flow is dispersed into multiple thin streams to reduce the impact force. However, the dispersed water flow leads to weakened cleaning power and is not suitable for scenarios with strong water flow requirements such as rinsing stains. Moreover, the mode switching of some products is complex, affecting the user experience. 3) Buffer-type water outlet faucet: A buffer device (such as a silicone pad, flow limiter) is added at the water outlet to slowly release the water flow. It will reduce the water flow speed, affecting the usage efficiency, and the buffer effect of some cheap products is not good, and splashing will still occur. 4) Intelligent induction control faucet: Controls the water flow switch and intensity through an infrared sensor to avoid sudden changes in water flow caused by manual operation. However, its cost is high, the maintenance process is complex, and the sensor is easily interfered by water stains and dirt, resulting in misjudgment. In summary, the anti-splash effect of the anti-splash faucets in the prior art is limited, which not only affects the user experience, but also has problems such as the decline of the anti-splash performance after long-term use and high maintenance costs. Summary of the Invention

[0003] Aiming at the defects existing in the prior art, the purpose of the present invention is to provide a household anti-splash faucet, the water outlet pipe of which can be flexibly designed in structure.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A household anti-splash faucet includes a water outlet pipe. The inlet of the water outlet pipe is a cold and hot water mixing area, and an acceleration component is arranged in the mixing area; an air passage is arranged in the outer wall of the water outlet pipe for introducing air into the water for mixing.

[0006] Preferably, the air passage and the water outlet pipe are integrally structured. The air passage can be made of the same material as the water outlet pipe. At the same time, the air passage and the water outlet pipe can be integrally formed. For example, the water outlet pipe and the air passage can be cast.

[0007] In addition to the integrated design of the ventilation duct and the outlet pipe, the ventilation duct can also be designed as an independent hose extending in the outer wall of the outlet pipe. Such a structure is simpler than the integrated structure. The ventilation duct has an air inlet and an air outlet. The air inlet is used to suck air into the ventilation duct, and the air comes out of the ventilation duct through the air outlet and mixes with water there.

[0008] Preferably, the air outlet is arranged adjacent to the acceleration component. The advantage of this is that the air outlet is arranged at the maximum water flow velocity. Since the pressure is the lowest here, air can be reliably sucked in and introduced into the water.

[0009] Preferably, the outlet pipe has a water outlet, and the water outlet and the air inlet of the ventilation duct are arranged together. The water gushes out from the water outlet, and the air inlet of the ventilation duct is arranged beside the water outlet, so that air is also sucked in here. This design is particularly advantageous when the outlet pipe is opened, avoiding the necessity of making an additional opening on the outer wall to introduce air.

[0010] Preferably, a plurality of through holes are provided inside the acceleration component. The through holes are tapered with a larger diameter at the bottom and a smaller diameter at the top along the water flow direction, accelerating the water flow passing through the acceleration component.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] In the present invention, the ventilation duct is arranged inside the outer wall of the outlet pipe, and the mixing of air and water can be carried out at any position inside the outlet pipe. It is no longer required to mix at the end of the outlet pipe. In this way, the end of the outlet pipe can be constructed and designed more flexibly. For example, the end of the outlet pipe can be designed with a polygonal or elliptical cross-sectional shape.

[0013] The present invention utilizes the principle of fluid pressure. The acceleration component is arranged on the inlet side in the outlet pipe along the water flow direction. The water has been accelerated and mixed with air when entering the outlet pipe through the acceleration component. The fluid formed by the mixing of air and water has sufficient time and space for uniform mixing throughout the entire length of the outlet pipe and finally flows out smoothly from the end.

[0014] The structure of the present invention is simple, with low manufacturing and maintenance costs, good anti-sputtering effect, and no problems such as blockage will occur during long-term use. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 3 is in the closed position Figure 1 a schematic diagram of the embodiment. Detailed implementation manners

[0018] The present invention will be further described below in conjunction with preferred implementation manners and the accompanying drawings.

[0019] Figure 1 An embodiment of the present invention is shown. This household anti-splash faucet is equipped with a cold water handle 1 and a hot water handle 2, and the hot and cold water are mixed in the mixing area 3. The household anti-splash faucet includes a water outlet pipe 4. The faucet shown is a three-hole faucet. The present invention can also be applied to two-hole faucets or single-lever mixers.

[0020] When the household anti-splash faucet is opened, water flows out from the water outlet pipe 4. For this purpose, the water outlet pipe 4 has a water outlet 5.

[0021] In addition, an accelerating component 6 is arranged in the mixing area 3 along the water flow direction, and the water flows through the accelerating component 6 and is accelerated during this period, as shown according to Figure 2 shown.

[0022] The water outlet pipe 4 is limited by an outer wall 7 facing the outside. An air vent 8 is arranged in the outer wall 7, and air from the surroundings is sucked in through the air vent 8, as indicated by the arrow 9, and the air flows in the direction opposite to the water flow direction.

[0023] The air vent 8 has an air inlet 10 and an air outlet 11. The air inlet 10 is preferably arranged at the height of the water outlet 5. In particular, it can end flush with the water outlet 5.

[0024] The reference shows in enlarged scale the Figure 1 implementation details in Figure 2 . The accelerating component 6 includes a plurality of tapered through holes 12, and these through holes 12 gradually narrow from bottom to top along the water flow direction, thereby realizing the acceleration of the water flow. A negative pressure is formed by the high speed of the water flow to suck in air in the direction of the arrow 9. The air flows out from the air outlet 11, enters the water above the accelerating component 6 and mixes with it. A vortex water / gas mixed fluid 13 is generated and a determined jet flows out from the water outlet 5.
