In the present embodiment, the air inlet space S is formed by the cavity 11 and the water separator 12, but the present invention is not limited thereto. For example, in other embodiments of the present invention, which are not shown, the air inlet space S may be formed by being surrounded by only the cavity 11.

Furthermore, the chamber 11 includes a bottom wall 111 and a circular sidewall 112 connected to the bottom wall 111 (periphery). Wherein, the bottom wall 111 is formed with a plurality of liquid-gas outlets 113 (communicating with the air intake space S and in a penetrating manner), and the annular side wall 112 is formed with an air inlet 114 communicating with the air intake space S (in a penetrating manner); that is, the intake space S may communicate with an external space through the plurality of liquid-gas outlets 113 and the intake port 114.

In more detail, the annular sidewall 112 is substantially circular and defines an axis C perpendicular to the center of the bottom wall 111, the liquid and gas outlets 113 are disposed separately from each other, and the distances between the centers of the liquid and gas outlets 113 and the axis C are the same. In the present embodiment, the plurality of liquid and gas outlets 113 are located in an area within 120 degrees of the bottom wall 111 centered on the axis C, and the plurality of liquid and gas outlets 113 have different inner diameters, but the present invention is not limited thereto.

The water separator 12 is detachably mounted on the annular side wall 112 and is located in the area surrounded by the bottom wall 111 and the annular side wall 112, but the water separator 12 cannot rotate relative to the chamber 11. That is, the air inlet space S is formed by the water separator 12, the bottom wall 111 and the annular side wall 112.

Further, the water separator 12 is formed with a plurality of water inlet channels 121, and the positions of the plurality of water inlet channels 121 respectively correspond to the plurality of liquid-gas outlets 113 along the direction parallel to the axis C, each water inlet channel 121 and the corresponding liquid-gas outlet 113 are arranged at intervals and communicated with the air inlet space S, and the inner diameter of each water inlet channel 121 is smaller than the inner diameter of the corresponding liquid-gas outlet 113. Furthermore, the water separator 12 is formed with a plurality of positioning grooves 122 outside the plurality of water inlet channels 121, each positioning groove 122 is not communicated with the air inlet space S, and the distances between the plurality of positioning grooves 122 and the axis C are the same.

In this embodiment, the water separator 12 includes a tray 123 mounted on the annular sidewall 112 and a column 124 extending from the bottom surface of the tray 123. Each of the water inlet channels 121 penetrates through the tray body 123 and the column 124, and each of the positioning slots 122 is recessed on the top surface of the tray body 123. In another aspect, the projection area formed by the orthogonal projection of the column 124 toward the top surface of the tray 123 is located inside the positioning slots 122, but the invention is not limited thereto.

In addition, in a cross section of the water outlet section 1 perpendicular to the axis C, the cross-sectional areas of the plurality of water inlet channels 121 are different, and the cross-sectional area of any one of the water inlet channels 121 is not equal to the sum of the cross-sectional areas of at least two of the rest of the water inlet channels 121. However, in other embodiments not shown in the present invention, the cross-sectional areas of the water inlet channels 121 may be the same; alternatively, the cross-sectional area of any one of the water inlet channels 121 is equal to the sum of the cross-sectional areas of at least two of the remaining water inlet channels 121.

The water outlet pipe 13 is connected to the bottom wall 111, and the water outlet pipe 13 is communicated with the corresponding water inlet channel 121 and the air inlet space S through any one of the liquid and gas outlets 113.

Furthermore, the check valve 15 is installed in the air inlet pipe 14, and the check valve 15 can be used to connect to the ozone generator, so that the gas generated by the ozone generator can enter the air inlet space S through the check valve 15, and the check valve 15 can prevent the gas or liquid in the air inlet space S from flowing to the ozone generator.

The water inlet section 2 comprises a pipe body 21, an adjusting part 22 connected to the inner edge of the pipe body 21, and a plurality of positioning components 23. One end of the fixing rod 4 is fixed to the adjusting part 22 of the water inlet section 2, and the other parts of the fixing rod 4 penetrate through the inner washer 3, the water separator 12 and the cavity 11 along the axis C, so that the water inlet section 2 can rotate relative to the water outlet section 1 around the axis C.

In more detail, the central line of the tube 21 is overlapped with the axis C, and the outer edge of the tube 21 is preferably aligned with the outer edge of the annular sidewall 112 of the cavity 11, but the invention is not limited thereto. A screw-connection portion 211 is formed at an inner edge of a top portion (e.g., an upper half portion of the tube body 21 in fig. 6) of the tube body 21 for connecting to a water source (e.g., a water pipe connected to a faucet), so that water flowing out of the water source can sequentially flow out of the adjustable venturi tube 100 through the water inlet section 2 and the water outlet section 1.

The adjusting part 22 is connected to the inner edge of the bottom of the tube 21 (e.g. the lower half of the tube 21 in fig. 6), and the adjusting part 22 is formed with a water inlet channel 221, and the water inlet channel 221 is toward a projection space through which the water outlet section 1 is orthographically projected, and preferably completely covers the plurality of water inlet channels 121. In the embodiment, the water inlet channel 221 is an arc channel with the axis C as a center, but the invention is not limited thereto. For example, in other embodiments not shown in the present invention, the water inlet channel 221 may also be a channel structure including a circular arc-shaped region.

Furthermore, the adjusting part 22 is pivotally connected to the water separator 12 along the axis C in a rotatable manner, so that the water inlet section 2 can rotate relative to the water outlet section 1, and the water inlet section 2 and the water separator 12 move relatively. In this embodiment, the positioning elements 23 are installed on at least one of the adjusting portion 22 and the tube 21, and the positions of the positioning elements 23 respectively correspond to (or face) the positioning slots 122, so that the positioning elements 23 are respectively inserted into and elastically pressed against the positioning slots 122.

In more detail, in the present embodiment, any one of the positioning assemblies 23 includes a compression spring 231 and a propping rod 232 connected to the compression spring 231, but the invention is not limited thereto. In any one of the positioning assemblies 23, the compression spring 231 is disposed in at least one of the adjusting portion 22 and the tube body 21, and the abutting column 232 is partially embedded and elastically pressed in the corresponding positioning slot 122.

Accordingly, in the present embodiment, the adjustable venturi tube 100 can position the water inlet section 2 at different predetermined positions relative to the water outlet section 1 by the cooperation of the positioning elements 23 and the positioning slots 122.

In the present embodiment, the adjusting portion 22 is only connected to a space 212 surrounded by the screw-in portion 211 through the water inlet channel 221, and the space 212 surrounded by the screw-in portion 211 can be selectively connected to at least one of the water inlet channels 121 through the water inlet channel 221 by the relative movement between the water inlet section 2 and the water separator 12. For example, as shown in fig. 8 to 11, the space 212 can be selectively communicated with one of the water inlet channels 121 through the water inlet channel 221.

Further, the space 212 surrounded by the screw-connection portion 211 can be rotated relative to the water outlet section 1 by the water inlet section 2, and selectively communicates with at least two of the water inlet channels 121 of the plurality of water inlet channels 121 via the water inlet channel 221. For example, as shown in fig. 12 to 15, the space 212 can be selectively communicated with two of the water inlet channels 121 via the water inlet channel 221; alternatively, the space 212 can be selectively communicated with the three water inlet passages 121 via the water inlet passage 221.

Accordingly, the adjustable venturi 100 can maintain the physical phenomenon of air intake of the adjustable venturi 100 by the selection of the water inlet passage 121 under different water pressure environments through the structural design (e.g., the selective cooperation between the water inlet passage 221 and the plurality of water inlet passages 121). Furthermore, the adjustable venturi 100 can be used to provide different water flow rates, so as to have a multi-stage water flow adjustment function, thereby meeting different water flow rates and air intake requirements and application environments.

Further, the inner gasket 3 is sandwiched between the water separator of the water outlet section 1 and the adjusting portion 22 of the water inlet section 2. The inner gasket 3 surrounds and is fixed to the water inlet passage 221, and the inner gasket 3 abuts against the water separator 12 without a gap, so that the water inlet passage 221 and the water inlet passages 121 can maintain a seal therebetween. In the embodiment, the inner washer 3 is a one-piece structure formed integrally, and the inner washer 3 has 180-degree rotational symmetry with respect to the axis, but the invention is not limited thereto.

It should be noted that, although the cavity 11 of the water outlet section 1 and the tube 21 of the water inlet section 2 are two separate components in the embodiment, the invention is not limited thereto. For example, in other embodiments not shown in the present invention, the cavity 11 of the water outlet section 1 and the tube body 21 of the water inlet section 2 may be integrally formed, and the water separator 12 is rotatably mounted on at least one of the cavity 11 and the tube body 21, so that the water separator 12 can rotate relative to the cavity 11 and the tube body 21, and the space 212 surrounded by the threaded portion 211 can selectively communicate with at least one of the water inlet channels 121 via the water inlet channel 221.
