Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, and in particular to a faucet product, especially a faucet spout. Background Technology

[0002] A faucet is a common name for a water valve, used to control the flow of water and thus saving water. Faucets are constantly being updated, evolving from old-fashioned cast iron faucets to electroplated knob faucets, and then to stainless steel single-temperature single-control faucets, stainless steel dual-temperature dual-control faucets, and semi-automatic kitchen faucets. Now, more and more consumers consider factors such as material, function, and design when purchasing faucets.

[0003] Prior art CN205446900U discloses a faucet, including a faucet body with a switch handle. A support is provided on the faucet body, and a cover is hinged to the support to cover the switch handle. A controller, a distance sensor, and an ultraviolet disinfection lamp are housed within the cover. The controller is connected to both the distance sensor and the ultraviolet disinfection lamp. When the cover is closed, it covers the switch handle. Simultaneously, the distance sensor within the cover detects a change in distance and sends a signal to the controller. The controller then activates the ultraviolet disinfection lamp to disinfect the switch handle, making the process convenient and quick.

[0004] However, in the process of implementing the technical solution in the prior art, the applicant discovered the following technical problems in the prior art:

[0005] Because existing faucets have complex structures and poor cleaning effects, an increase in water flow is needed to improve the cleaning effect, thus failing to achieve the goal of water conservation. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a faucet spout, which solves the technical problem that the existing faucet has a complex structure and unsatisfactory cleaning effect, and at least achieves one of the technical effects of simple structure and good cleaning effect.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0008] A faucet spout comprises a faucet connector, an air inlet, a water channel, a water-air mixing chamber, and a water outlet. The faucet connector is externally connected to the water outlet of the faucet. The water channel is located in the center of the faucet spout and extends through the faucet connector and the water-air mixing chamber. One end of the water-air mixing chamber is connected to the water outlet, and the other end is connected to the water channel. The end of the water-air mixing chamber away from the water outlet is connected to the air inlet via an air passage. The air inlet includes at least one air inlet perpendicular to the outer wall of the faucet spout. The air passage is located outside the outer wall of the water channel, and its width is smaller than the diameter of the water channel. The diameter of the water-air mixing chamber is larger than the diameter of the water channel. Air enters the water-air mixing chamber from the air inlet. Water flows through the water channel and mixes with the air in the water-air mixing chamber.

[0009] Preferably, the width of the air passage is less than 1 / 8 to 1 / 10 of the diameter of the water passage.

[0010] More preferably, the faucet connection includes an air inlet, which is perpendicular to the water flow channel.

[0011] More preferably, the faucet connection is also equipped with a detachable connector.

[0012] Preferably, one end of the detachable connector is threadedly connected to the faucet, and the other end of the detachable connector away from the faucet is threadedly connected to the faucet connection part.

[0013] More preferably, the water outlet is provided with a grid.

[0014] Preferably, the diameter of the air inlet is larger than the diameter of the air passage, and the air velocity flowing through the air passage is greater than the air velocity flowing through the air inlet.

[0015] Preferably, the diameter of the water-air mixing chamber is larger than the diameter of the water flow channel.

[0016] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0017] The above technical solution employs a series of technical means, including a connecting part, an air inlet, a water channel, a water-air mixing chamber, and a water outlet. The water channel is located in the center of the faucet spout and connects the faucet connecting part and the water-air mixing chamber. One end of the water-air mixing chamber is connected to the water outlet, and the other end is connected to the water channel. The end of the water-air mixing chamber furthest from the water outlet is connected to the air inlet via an air passage. The air inlet includes at least one air inlet perpendicular to the outer wall of the faucet spout. The air passage is located outside the outer wall of the water channel, with a width smaller than the diameter of the water channel, and the diameter of the water-air mixing chamber is larger than the diameter of the water channel. This allows air to enter the water-air mixing chamber from the air inlet; water flows through the water channel and mixes with the air in the water-air mixing chamber. No additional electrically powered atomizing device is required, simplifying installation and the overall structure. Furthermore, according to the principle of fluid mechanics that high speed results in low pressure and low speed results in high pressure, the water flows at a high speed in the water channel, while the air in the atmosphere is relatively still. Since the air inlet and the water-air mixing chamber are connected, and the water-air mixing chamber is connected to the water channel, the pressure in the water-air mixing chamber is lower than the air pressure in the atmosphere. Air is drawn in from the air inlet and flows through the air channel into the water-air mixing chamber.

[0018] Tap water is mixed with air in the water-air mixing chamber and atomized to a certain extent. The water molecules in the atomized water are smaller than those in unatomized water, thus providing a certain degree of sterilization. The relatively smaller water molecules penetrate the surface of the object being cleaned more easily than normal tap water, effectively solving the technical problems of complex faucet structures and poor cleaning performance in existing technologies, thereby achieving a simple structure and excellent cleaning effect.

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Current faucets are used by directly pointing the spout at the object being cleaned. However, the limited diameter of the spout prevents the water flow area from being increased, affecting the cleaning effect. Replacing the spout with a larger diameter one often causes problems. Adding pressure boosting functions further complicates the faucet's structure and makes installation more difficult.

[0026] The technical solution of this application provides a faucet spout that solves the problems of unsatisfactory cleaning effect and complex structure in the prior art. It achieves the beneficial effects of simple structure and improved cleaning effect by providing a faucet spout that is perpendicular to the water channel 300 and the air inlet 210.

[0027] The overall concept of the implementation scheme of this utility model to solve the above-mentioned technical problems is as follows:

[0028] A faucet spout includes a faucet connector 100, an air inlet 200, a water flow channel 300, a water-air mixing chamber 400, and a water outlet 500. The water-air mixing chamber 400 is connected to both the air inlet 200 and the water outlet 500, and is also connected to both the water flow channel 300 and the water outlet 500. The air inlet 200 and the water-air mixing chamber 400 are connected by a narrow air passage 220, and the air inlet 200 has an air inlet 210 that penetrates the outer wall of the spout. Water flows out of the faucet, enters the water flow channel 300 of the faucet spout through the faucet connector 100, passes through the water-air mixing chamber 400, and then flows out of the water outlet 500.

[0029] Based on the principle of fluid mechanics that high speed results in low pressure and low speed results in high pressure, the water flows at a high speed in the water channel 300, while the air is relatively still in the atmosphere. Since the air inlet 200 and the water-air mixing chamber 400 are connected, and the water-air mixing chamber 400 is connected to the water channel 300, the pressure in the water-air mixing chamber 400 is relatively lower than that in the atmosphere. Air flows from the air inlet 210 through the air passage 220 and is drawn into the water-air mixing chamber 400.

[0030] Tap water is mixed with air in the water-air mixing chamber 400 and atomized to a certain extent. The water molecules in the atomized water after the water-air mixture are smaller than those in unatomized water, thus playing a certain role in sterilization. The relatively smaller water molecules penetrate the surface of the object being cleaned more easily than normal tap water, thereby improving the cleaning effect.

[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0032] A type of faucet spout, such as Figure 1-2 As shown, it mainly consists of a faucet connector 100, an air inlet 200, a water channel 300, a water-air mixing chamber 400, and a water outlet 500. The faucet connector 100 is connected to the water outlet of the faucet. The water channel 300 is located in the center of the faucet spout and runs through the faucet connector 100 and the water-air mixing chamber 400. One end of the water-air mixing chamber 400 is connected to the water outlet 500, and the end of the water-air mixing chamber 400 away from the water outlet 500 is connected to the air inlet 200 through an air passage 220. The air passage 220 is located outside the outer wall of the water channel 300.

[0033] The width of the air passage 220 is much smaller than the diameter of the water passage 300. Specifically, the width of the air passage 220 is less than 1 / 8 to 1 / 10 of the diameter of the water passage 300.

[0034] Household water typically has more than one tap, and taps don't always require water-air mixing. In addition, taps have different spout sizes. To further improve the adaptability of tap spouts, a detachable connector 110 is added. When water-air mixing is not needed, the tap spout can be removed using the detachable connector 110.

[0035] A type of faucet spout, such as Figure 3-4 As shown, it consists of a faucet connection part 100, an air inlet part 200, a water flow channel 300, a water-air mixing chamber 400, and a water outlet part 500. The faucet connection part 100 includes a detachable connector 110.

[0036] Specifically, one end of the detachable connector 110 is connected to the faucet outlet, and the other end is connected to the faucet spout 100.

[0037] To further enhance the compatibility of the faucet spout, detachable connectors 110 of different specifications are added to match different faucets. The size of the end of the detachable connector 110 that connects to the faucet is designed to match the size of the faucet. The detachable connector 110, the faucet connection part 100 of the faucet spout, and the faucet itself can all be separated.

[0038] The uniformity of water output has a certain impact on the cleaning effect. In order to improve the cleaning effect, a grid 510 is added to the water outlet section 500 to make the water-air mixture water output distribution more uniform.

[0039] Tap water enters the water-air mixing chamber 400 through the water flow channel 300 from the faucet connection 100. Simultaneously, according to the principle of fluid mechanics that higher velocity results in lower pressure and lower velocity in results in higher pressure, the water flows faster in the water flow channel 300 than the relatively still air in the atmosphere. Because the air inlet 200 and the water-air mixing chamber 400 are connected, and the water-air mixing chamber 400 is connected to the water flow channel 300, the pressure in the water-air mixing chamber 400 is relatively lower than that in the atmosphere. Air flows from the air inlet 210 through the air passage 220 and is drawn into the water-air mixing chamber 400. The mixing of water and air in the water-air mixing chamber 400 generates turbulent vortices of varying degrees, further accelerating the mixing process.

[0040] Since the air passage 220 is smaller than the water passage 300 and the air inlet 210, the air speed in the air passage 220 is greater than the air speed in the air inlet 210. When the air comes to the water-air mixing chamber 400, the air speed decreases and mixes with the water because the width of the air passage 220 is also smaller than the inner diameter of the water-air mixing chamber 400.

[0041] When air flows through air passage 220, because air passage 220 is smaller than both water passage 300 and air inlet 210, the air velocity in air passage 220 is greater than the air velocity in air inlet 210. When the air reaches water-air mixing chamber 400, because the width of air passage 220 is also smaller than the inner diameter of water-air mixing chamber 400, the air velocity decreases. The air leaving air passage 220 has a high velocity, while the air in water-air mixing chamber 400 has a low velocity. The collision of the fast and slow air creates air turbulence.

[0042] The diameter of the water flow channel 300 is smaller than the inner diameter of the water-air mixing chamber 400. The water flow in the water-air mixing chamber 400 is slower than the water flow in the water flow channel 300. The fast water flow that has just left the water flow channel 300 collides with the relatively slow water flow in the water-air mixing chamber 400, generating a turbulent vortex in the water.

[0043] The intertwining of water vortices and air vortices facilitates rapid mixing of water and air, which in turn allows the water to atomize to some extent.

[0044] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
