Description

Technical Field

[0001] The invention relates to the technical field of bathroom products, and in particular to an anti-blocking faucet. Background Art

[0002] In order to save water and make the water flow more beautiful, existing faucets usually install a bubbler at the water outlet; the bubbler can fully mix the water and air flowing through it, so that the water flow has a foaming effect. With the addition of air, the flushing force of the water is greatly improved, thereby effectively reducing water consumption and saving water. However, current bubblers are composed of a water-saving barrier net and many layers of mesh with a foaming effect. Therefore, when in use, small particles of impurities and sediment are often blocked at the barrier net or mesh. With long-term use, impurities and sediment will accumulate in large quantities and eventually cause blockage, affecting the normal use of the faucet. Summary of the invention

[0003] The invention discloses an anti-blocking faucet, aiming to improve the problem that the existing faucet is easily blocked.

[0004] The present invention adopts the following scheme:

[0005] A blockage-proof faucet comprises a main body and a valve core built into the main body, the main body being provided with at least one water inlet and a water outlet, the water inlet and the water outlet being connected or blocked by the valve core, a water outlet nozzle being provided at the water outlet end of the main body, a first filter being provided on the water outlet nozzle, the water inlet of the main body being connected with a water outlet channel of an air-water mixing chamber, the water inlet channel of the air-water mixing chamber being connected with a water inlet device, and at least one air inlet hole connected to the outside being provided on the water inlet channel.

[0006] As a further improvement, the water outlet nozzle includes a water outlet head, the water outlet head has a water inlet cavity and a water outlet hole connected to the water inlet cavity, and a second filter is provided in the water inlet cavity.

[0007] As a further improvement, the water outlet also includes a shell, a water flow part adaptably connected to the shell, a moving part built into the shell, and an elastic part disposed between the moving part and the inner wall of the shell. The water outlet head is adaptably connected to the water flow part, and the moving part is configured to switch between a first position and a second position through the impact of water flow and the action of the elastic part.

[0008] As a further improvement, the moving part is provided with a check portion, on which a sealing member is sleeved. The check portion is arranged on the water flow channel of the water flow member and moves synchronously with the moving part to control the conduction or blocking of the water path between the water flow channel and the water outlet head.

[0009] As a further improvement, the main body has a rotatable curved pipe portion, and the water outlet nozzle is detachably arranged on the curved pipe portion.

[0010] As a further improvement, the water inlet flow channel has an acceleration section with a cross-section that decreases step by step from the fluid direction, and a negative pressure chamber arranged at the outlet end of the water inlet flow channel.

[0011] As a further improvement, the air inlet hole is arranged along the outer wall of the water inlet channel and is connected with the negative pressure chamber.

[0012] As a further improvement, the air inlet holes are arranged along the circumference of the water inlet channel.

[0013] As a further improvement, the valve core is a ceramic valve core, which is adaptably connected to a handle, and the handle is manipulated in an operable manner to adjust the valve core.

[0014] As a further improvement, the valve core is a solenoid valve, the solenoid valve is electrically connected to a control module, and the opening and closing of the solenoid valve is controlled by the control module.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0016] The anti-clogging faucet of the present application connects the main body with the gas-water mixing chamber so that gas is dissolved in the water flow. When the water flow with gas passes through the first filter screen of the water outlet, it is rectified to form a water flow with uniform bubbles and spray out from the water outlet. It is easy to understand that in the present application, there is no need to set up multiple layers of filter screens or mesh to repeatedly cut the water flow, and water with bubbles can be sprayed out, thereby avoiding the problem that when multiple layers of mesh are set, the mesh holes are easily blocked, causing the faucet to be blocked. Compared with the prior art, the advantages of the present application are obvious. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Example

[0034] Combination Figures 1 to 4The present embodiment provides an anti-blocking faucet, comprising a main body 1 and a valve core 2 built into the main body 1, the main body 1 is provided with at least one water inlet 11 and a water outlet 12, the water inlet 11 and the water outlet 12 are connected or blocked by the valve core 2, a water outlet nozzle 3 is installed at the end of the water outlet 12 of the main body 1, a first filter screen 31 is provided on the water outlet nozzle 3, the water inlet 11 of the main body 1 is connected with a water outlet channel 41 of an air-water mixing chamber 4, the water inlet channel 42 of the air-water mixing chamber 4 is connected with a water inlet device, and at least one air inlet hole 43 connected to the outside is provided on the water inlet channel 42. For example, the water inlet device is linked with the faucet, that is, when the water inlet 11 and the water outlet 12 of the faucet are connected, the water inlet pipe of the water inlet device is connected, and the water flows from the water inlet pipe through the water inlet channel 42 into the gas-water mixing chamber 4. When the water flows through the water inlet channel 42, it mixes with the gas input from the air inlet hole 43 to form dissolved gas water. The dissolved gas water flows from the water outlet channel 41 through the water inlet 11 into the body 1, and then flows from the water outlet 12 to the water outlet 3. The gas in the water flow is evenly divided by the first filter 31 on the water outlet 3, and finally sprayed from the water outlet 3 to the user side. Among them, the gas-water mixing chamber 4 can be connected to the water inlet 11 by a water pipe.

[0035] It should be noted that, in this embodiment, by connecting the main body 1 with the gas-water mixing chamber 4, gas is dissolved in the water flow, and the water flow with gas is divided more evenly when passing through the first filter screen 31 of the water outlet 3, forming a water flow with uniform bubbles to be sprayed from the water outlet 3. It is easy to understand that in this embodiment, water with bubbles can be sprayed without multi-layer filters or mesh cutting the water flow, thereby avoiding the problem that when multi-layer mesh is set, the mesh holes are easily blocked, resulting in faucet blockage.

[0036] In another embodiment, the water outlet 3 includes a water outlet head 32, the water outlet head 32 has a water inlet cavity 321 and a water outlet hole 322 connected to the water inlet cavity 321, and a second filter 33 is arranged in the water inlet cavity 321. For example, the first filter 31 is used for rectification, and the second filter 33 is used for cutting bubbles in water.

[0037] Preferably, the water outlet 3 further comprises a housing 34, a water-passing member 35 adapted to be connected to the housing 34, a moving member 36 built into the housing 34, and an elastic member 37 (such as a spring) disposed between the moving member 36 and the inner wall of the housing 34. The water outlet head 32 is adapted to be connected to the water-passing member 35. The moving member 36 is configured to switch between a first position and a second position through the impact of water flow and the action of the elastic member 37. The moving member 36 is provided with a check portion 361, and a sealing member 38 (such as a sealing ring) is sleeved on the check portion 361. The check portion 361 is disposed on the water flow channel 351 of the water-passing member 35, and the check portion 361 moves synchronously with the moving member 36 to control the conduction or blocking of the water path between the water flow channel 351 and the water outlet head 32. When the moving member 36 is in the first position, the water inlet 11 is connected to the water outlet 12, and the water flow at the water outlet 12 impacts the moving member 36, so that the moving member 36 compresses the elastic member 37 and moves toward the water outlet 322. At this time, the check portion 361 is separated from the water flow channel 351, and the water path between the water flow channel 351 and the water outlet 322 is connected, and the water flows from the side of the check portion 361 to the water outlet 322. When the moving member 36 is in the second position, the water inlet 11 is blocked from the water outlet 12, and under the elastic force of the elastic member 37, the moving member 36 moves away from the water outlet 322 until the check portion 361 and the water flow channel 351 squeeze the sealing member 38 to seal, so that the water path between the water flow channel 351 and the water outlet 322 is blocked. That is, when the water outlet 12 is connected to the water inlet 11, water flows out of the water outlet 322, and when the water inlet 11 is blocked from the water inlet 11, no water flows out of the water outlet 322, and at this time, the water flow channel 351 is sealed with the check portion 361, so as to prevent the water outlet 12 from being polluted by dust or the like entering from the water outlet 322 when the water flow is closed.

[0038] In a preferred embodiment, the body 1 has a rotatable curved pipe portion 13, and the direction of water outlet can be adjusted by rotating the curved pipe portion 13. In addition, the water outlet 3 is detachably arranged on the curved pipe portion 13, and the housing 34 of the water outlet 3 is connected to the curved pipe portion 13 by threads, which is convenient for disassembly and assembly of the water outlet 3, and convenient for cleaning and replacement of the water outlet 3.

[0039] On the basis of the above-mentioned embodiment, in an optional embodiment of the present invention, the water inlet channel 42 has an acceleration section 421 whose cross section decreases step by step from the fluid direction, and a small-diameter section 422 arranged on the downstream side of the acceleration section 421 for connecting to the mixing chamber. The acceleration section 421 and the small-diameter section 422 are surrounded by a cavity wall arranged in the water inlet portion 44, and a negative pressure cavity 441 is formed between the cavity wall and the inner wall of the water inlet portion 44. At least one air inlet hole 43 for connecting to the negative pressure cavity 441 is provided along the circumference of the water inlet portion 44. The water flows in from the water inlet portion 44 and is accelerated by the acceleration section 421. In the process of the water flow accelerating through the small-diameter section 422, a negative pressure is formed in the negative pressure cavity 441. It is easy to understand that the faster the water flow velocity, the greater the negative pressure it generates. The greater the negative pressure in the negative pressure cavity 441, the faster the air intake velocity of the air inlet hole 43, the better the air dissolving effect of the water flow, and the corresponding improvement of the water bubble effect sprayed from the water outlet 3.

[0040] Preferably, the air inlet hole 43 is arranged along the outer wall of the water inlet channel 42 and is connected to the negative pressure chamber 441. The air inlet hole 43 can be arranged with one, two, three, four, etc., without specific limitation. In this embodiment, preferably, there are two air inlet holes 43 symmetrically arranged along the circumference of the water inlet channel 42.

[0041] Based on the above embodiment, in an optional implementation of the present invention, the valve core 2 is a ceramic valve core 2, which is adapted to be connected with the handle 5, and the handle 5 is manipulated in an operable manner to adjust the valve core 2. The internal structure of the valve core 2 is prior art and will not be described in detail here.

[0042] In another embodiment, the valve core 2 is a solenoid valve, which is electrically connected to a control module, and the opening and closing of the solenoid valve is controlled by the control module. For example, a sensor is provided on the body 1, and the sensor is electrically connected to the control module. When the sensor detects a user signal, the signal is transmitted to the control module, so that the control module controls the opening of the solenoid valve, but it is not limited thereto.

[0043] The above are only preferred implementations of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
