A rectifier and a water tap

Abstract

A rectifier and faucet are provided, comprising a first cavity and a second cavity. The first cavity is connected to the second cavity via a first water level passage and a first air inlet. The second cavity is connected to the atmospheric environment via a second air inlet. Air is supplied to the first and second cavities respectively through the first and second air inlets, allowing air to contact the bubbles in the water flowing through the first and second cavities, thereby increasing the size of the bubbles. After the bubbles contact the atmosphere, the bubble walls are connected to the atmosphere. Under the action of gravity, the water film at the top of the bubbles flows downward, and the surface tension causes the water film to contract and thin, causing the bubbles to burst inside the rectifier. This reduces the bubble content in the water flow, reduces the possibility of large bubbles bursting at the outlet, improves the undesirable phenomena such as water flow interruption and shaking, and enhances the user experience.

Description

Technical Field

[0001] This utility model relates to the field of rectifier technology, and in particular to a rectifier and a water tap. Background Technology

[0002] When water is dispensed from a device such as a faucet, if the water flow contains a lot of air bubbles when dispensing hot or boiling water, the faucet may shake due to the bursting of these bubbles. At the same time, many small air bubbles can easily coalesce into large air bubbles, which can burst at the faucet outlet, causing the water flow to stop and resulting in a poor water-holding experience for the user. Utility Model Content

[0003] This utility model provides a rectifier to reduce the amount of air bubbles in the water flow, thereby reducing the shaking that occurs when the water is flowing from the faucet and improving the user experience.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A rectifier is provided with an inlet and an outlet, and also with a first cavity and a second cavity. The first cavity is connected to the inlet, and the second cavity is connected to the outlet. The first cavity is connected to the second cavity through a first water level passage.

[0006] The first cavity is connected to the second cavity through the first air inlet, and the second cavity is connected to the atmospheric environment through the second air inlet. Air is supplied to the first cavity and the second cavity through the first air inlet and the second air inlet respectively, so that the air comes into contact with the bubbles in the water flowing through the first cavity and the second cavity.

[0007] Furthermore, it includes an outer shell and an inner shell disposed within the outer shell. The space enclosed by the inner side of the inner shell constitutes a first cavity. At least a portion of the space of the second cavity is formed by the space enclosed by the outer shell and the inner shell. The inner shell is provided with a first air inlet and a first water outlet, and the outer shell is provided with a second air inlet.

[0008] Furthermore, the inner shell has a plurality of first air inlets arranged in a circumferential array on its side wall, each first air inlet constituting a first air inlet position; the bottom of the inner shell has a plurality of water passage holes, each water passage hole constituting a first water passage position; the outer shell has a plurality of second air inlets arranged in a circumferential array on its side wall, each second air inlet constituting a second air inlet position.

[0009] Furthermore, it also includes a flow stabilizer, which is located at the end away from the water outlet and has several flow stabilizing holes that are connected to the first cavity.

[0010] Furthermore, it also includes a guide post, which passes through the first cavity and the second cavity. The flow stabilizer is located on the outside of the guide post and extends radially along the guide post. The guide post contains a first filter screen. The flow stabilizer and the guide post are integrally formed or separately formed.

[0011] Furthermore, it also includes a retaining ring, which is connected to the outer shell, and the inner shell and the flow stabilizer are connected to the retaining ring.

[0012] Furthermore, the inlet and outlet ends of the first water level are respectively equipped with a second filter screen and a third filter screen.

[0013] Furthermore, the outer shell is connected to an end cap, which is fitted over the guide post. The space enclosed by the end cap, the inner shell, and the outer shell constitutes a second cavity. The end cap is provided with several flow channels communicating with the second cavity.

[0014] Furthermore, the end cap has a guide section on the side facing away from the second cavity to guide the outflow of water from the flow channel onto the water outlet path of the guide column.

[0015] A water tap includes a water outlet body and a rectifier as described above, the rectifier being installed at the water outlet of the water outlet body.

[0016] The beneficial effects of this utility model are:

[0017] 1. The present invention proposes a rectifier comprising a first cavity and a second cavity. The first cavity is connected to the second cavity via a first water level channel and a first air inlet. The second cavity is connected to the atmospheric environment via a second air inlet. Air is supplied to the first and second cavities respectively through the first and second air inlets. The air contacts the bubbles in the water flowing through the first and second cavities, thereby increasing the size of the bubbles. After the bubbles contact the atmosphere, the bubble walls are connected to the atmosphere. Under the action of gravity, the water film at the top of the bubbles flows downward, and at the same time, the surface tension causes the water film to contract and thin, causing the bubbles to burst inside the rectifier. This reduces the bubble content in the water flow, reduces the possibility of large-sized bubbles bursting at the outlet, improves the adverse phenomena such as water flow interruption and shaking, and enhances the user experience.

[0018] 2. The rectifier proposed in this utility model has a first air intake position composed of multiple first air intake holes and a second air intake position composed of multiple second air intake holes, which improves the air intake efficiency of the first cavity and the second cavity and promotes the bursting of bubbles inside the rectifier.

[0019] 3. The rectifier proposed in this utility model has a flow stabilizing component with a flow stabilizing hole, a guide post located on the outside of the flow stabilizing component, and a first filter screen inside the guide post, so that most of the water flow and a small amount of bubbles flow out through the guide post, and the first filter screen is used to prevent a small amount of bubbles from accumulating into large bubbles, while a small amount of water flow and most of the bubbles pass through the flow stabilizing hole, the first cavity and the second cavity in sequence, causing the bubbles to burst.

[0020] 4. The rectifier proposed in this utility model has a second filter screen and a third filter screen respectively provided at the inlet and outlet of the first water level, which are used to cut the bubbles and cause the bubbles to burst.

[0021] 5. The rectifier proposed in this utility model has a guide part on the end cover that guides the water flow from the flow channel to the water flow path of the guide column, so as to promote the water flow from the guide column and the water flow from the second cavity to converge together and prevent the water flow from spreading out.

Detailed Implementation

[0032] The following is combined with Figures 1-8 This utility model will be described in detail.

[0033] This embodiment proposes a rectifier, which has an inlet and an outlet, and also has a first cavity 301 and a second cavity 302. The first cavity 301 is connected to the inlet, and the second cavity 302 is connected to the outlet. The first cavity 301 is connected to the second cavity 302 through a first water level passage.

[0034] The first chamber 301 is connected to the second chamber 302 through the first air inlet, and the second chamber 302 is connected to the atmospheric environment through the second air inlet. Air is supplied to the first chamber 301 and the second chamber 302 through the first air inlet and the second air inlet, respectively. The air comes into contact with the bubbles in the water flowing through the first chamber 301 and the second chamber 302, thereby increasing the size of the bubbles. After the bubbles come into contact with the air, the bubble walls are connected to the air. Under the action of gravity, the water film at the top of the bubble flows downward. At the same time, the surface tension causes the water film to shrink and become thinner, causing the bubbles to break inside the rectifier. This reduces the bubble content in the water flow, reduces the possibility of large bubbles breaking at the outlet, improves the adverse phenomena such as water flow interruption and shaking, and improves the user experience.

[0035] like Figure 2 As shown, the rectifier includes an outer shell 10 and an inner shell 20 disposed within the outer shell 10. The space enclosed by the inner side of the inner shell 20 constitutes a first cavity 301. At least a portion of the space of the second cavity 302 is formed by the space enclosed by the outer shell 10 and the inner shell 20. The inner shell 20 is provided with a first air inlet and a first water outlet, and the outer shell 10 is provided with a second air inlet. If the outer shell 10 is integrally formed with a water outlet, then the entire space of the second cavity 302 is formed by the space enclosed by the outer shell 10 and the inner shell 20. If the outer shell 10 forms a water outlet by connecting other components, then the space enclosed by the outer shell 10 and the inner shell 20 only constitutes a portion of the space of the second cavity 302.

[0036] like Figure 6 and Figure 7As shown, the inner shell 20 has a plurality of first air inlets 401 arranged in a circumferential array on its side wall, each first air inlet 401 constituting a first air inlet position; the outer shell 10 has a plurality of second air inlets 402 arranged in a circumferential array on its side wall, each second air inlet 402 constituting a second air inlet position. Therefore, the first air inlet position formed by multiple first air inlets 401 and the second air inlet position formed by multiple second air inlets 402 improve the air intake efficiency of the first cavity 301 and the second cavity 302, promoting the bursting of bubbles inside the rectifier. Figure 6 As shown, the bottom of the inner shell 20 is provided with several water passage holes 403, and each water passage hole 403 constitutes the first water passage level.

[0037] like Figure 2 As shown, the rectifier also includes a flow stabilizer 501, which is located at the end furthest from the outlet. The flow stabilizer 501 has several flow stabilizing holes 5011, which are connected to the first cavity 301. Figure 2 and Figure 5 As shown, the flow stabilizer 501 is located outside the guide post 502 and along the radial direction of the guide post 502. The guide post 502 passes through the first cavity 301 and the second cavity 302, and a first filter screen 801 is provided inside the guide post 502. In use, most of the water flow and a small amount of bubbles flow out through the guide post 502, and the first filter screen 801 is used to prevent a small amount of bubbles from accumulating into large bubbles. A small portion of the water flow and most of the bubbles flow out sequentially from the flow stabilizer 501, the first cavity 301, and the second cavity 302, causing the bubbles to burst. The flow stabilizer 501 and the guide post 502 are integrally formed or separately formed, and the water inlet ends of the flow stabilizer 501 and the guide post 502 constitute a water inlet.

[0038] like Figure 2 As shown, the rectifier also includes a retaining ring 60, which is connected to the outer casing 10. The inner casing 20 and the current stabilizer 501 are connected to the retaining ring 60. Figure 2 and Figure 7 As shown, the outer casing 10 is also connected to an end cap 70, which is fitted over the guide post 502. The end cap 70 has several flow channels 701 communicating with the second cavity 302. The water outlet of the flow channels 701 and the water outlet of the guide post 502 together form a water outlet. As mentioned above, the outer casing 10 forms a water outlet by connecting other components. Therefore, the second cavity 302 is formed by the space enclosed by the end cap 70, the inner casing 20, and the outer casing 10. Figure 4 As shown, the end cap 70 is provided with a guide part 702 that guides the water flow from the flow channel 701 to the water flow path of the guide column 502, so as to promote the water flow from the guide column 502 and the water flow from the second cavity 302 to converge together and prevent the water flow from spreading out.

[0039] like Figure 2As shown, the inlet end of the first water level is equipped with a second filter screen 802, and the outlet end of the first water level is equipped with a third filter screen 803, which are used to cut the bubbles and cause the bubbles to burst, further reducing the possibility of large bubbles bursting at the outlet.

[0040] This embodiment also proposes a water faucet (not shown), including a water outlet body and a rectifier as described above, which is installed at the water outlet of the water outlet body. Furthermore, the rectifier is suitable for water purifier faucets, especially instant hot water purifier faucets. The main hot water, carrying a small amount of bubbles, flows out through the guide column 502. The first filter 801 prevents the small amount of bubbles from accumulating into large bubbles. Most of the bubbles flow out from the flow stabilizer 501, the first cavity 301, and the second cavity 302 outside the rectifier, thereby repeatedly dispersing the bubbles and preventing the formation of large bubbles at the outlet.

[0041] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
