[0054] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0055] The most critical concept of the present invention is to use a liquid outlet with a rotationally symmetrical shape and a corresponding liquid outlet channel so that the output liquid flow column has a special shape.

[0056] Please refer to Figure 1-Figure 21 , a liquid outlet shape control device, comprising a liquid inlet end and a liquid outlet end, a flow channel for liquid flow is arranged between the liquid inlet end and the liquid outlet end, the liquid outlet end comprises a liquid outlet, the shape of the liquid outlet is a rotationally symmetrical figure, the liquid inlet end comprises a liquid inlet, the liquid inlet is arranged at one end of the flow channel, a liquid outlet channel is arranged between the liquid outlet and the other end of the flow channel, and the liquid outlet channel is connected to the flow channel, and the cross-sectional shapes of the liquid outlet channel at different positions along the liquid outlet direction are respectively rotationally symmetrical figures corresponding to the liquid outlet.

[0057] The working principle of the present invention is as follows: liquid flows out from the liquid outlet with a rotationally symmetrical shape along the liquid outlet channel to form a liquid flow column with a special shape; when the continuous liquid flows into the air to form a liquid flow column, the force between the liquid molecules makes the cross-sectional area of ​​the liquid flow column gradually tend to be circular.

[0058] As the liquid falls, the cross section of the liquid column will gradually become circular. After the cross section of the liquid column becomes circular, the pressure and inertia force inside the liquid will cause the cross section of the liquid column to continue to change into a shape that is symmetrical with the shape of the outlet.

[0059] As the liquid continues to fall, the cross section of the water column approaches a circle again; as the liquid continues to fall, the cross section of the water column becomes the same shape as the shape of the liquid outlet. As the liquid continues to fall, the cross section of the liquid flow column repeats a cycle along the falling direction, forming a non-rotating liquid flow column.

[0060] From the above description, it can be seen that the beneficial effect of the present invention is that: by using a liquid outlet with a rotationally symmetrical shape and a corresponding liquid outlet channel, the outflowing liquid column is subjected to the force of liquid molecules in the air to form a liquid column with a special shape.

[0061] Furthermore, the shape of the liquid outlet is an axisymmetric figure.

[0062] It can be seen from the above description that setting the shape of the liquid outlet to an axisymmetric figure allows the cross section of the liquid flow column to maintain relative balance when it changes, thereby increasing the duration of the liquid flow column with a special shape.

[0063] Furthermore, the liquid outlet channel is rotationally twisted with the central axis of the liquid outlet channel as the rotation center, and the cross-sectional shapes of the rotationally twisted liquid outlet channel at different positions along the liquid outlet direction are rotationally symmetrical figures corresponding to the liquid outlet.

[0064] From the above description, it can be seen that by using a liquid outlet with a rotationally symmetrical shape and a corresponding rotationally twisted liquid outlet channel, when the liquid flows out along the rotationally twisted liquid outlet channel to form a liquid flow column, a centrifugal force rotating around the central axis of the liquid flow column is generated; depending on the degree of rotational twisting of the liquid outlet channel, the centrifugal force can offset part or all of the forces between liquid molecules, so that the liquid flow column can resist deformation and form a liquid flow column with a special shape.

[0065] Furthermore, the area of ​​the liquid outlet is smaller than the cross-sectional area of ​​the liquid outlet channel, the inner wall of the liquid outlet channel is provided with a guide section, the guide section is connected to the liquid outlet, and the cross-sectional area of ​​the guide section is equal or decreases along the liquid outlet direction.

[0066] From the above description, it can be seen that a guide section is provided on the inner wall of the liquid outlet channel, which is used to limit the flow direction of the liquid so that it tends to flow smoothly, so that the liquid flows from the part with a large flow cross-sectional area to the part with a small flow cross-sectional area; under the action of pressure, the flow of the liquid tends to be smooth, so that the output liquid flow column can maintain a special shape for a long time.

[0067] Furthermore, at least one of the flow channel and the liquid outlet channel is provided with a slow flow section, the cross-sectional area of ​​the slow flow section decreases along the liquid outlet direction, and the rate of change of the cross-sectional area of ​​the slow flow section decreases along the liquid outlet direction.

[0068] From the above description, it can be seen that setting a slow flow section in the flow channel or the liquid outlet channel has a certain liquid guiding effect, and at the same time can limit the flow direction of the liquid to make it tend to a smooth flow, and the cross-sectional area change rate of the slow flow section decreases along the liquid outlet direction, which can further improve the slow flow effect.

[0069] Furthermore, the liquid outlet channel is provided with at least one slow flow section.

[0070] It can be seen from the above description that a plurality of slow flow sections can be provided in the liquid outlet channel to form a multi-level slow flow, thereby ensuring that the liquid in the flow channel flows smoothly.

[0071] Furthermore, at least one slow flow section is provided in the flow channel.

[0072] It can be seen from the above description that a plurality of slow flow sections can be provided in the flow channel to form a multi-level slow flow, thereby ensuring that the liquid in the flow channel flows smoothly.

[0073] Furthermore, the shapes of the cross sections of the flow channel at different positions along the liquid outlet direction are respectively the same, the cross section of the flow channel is a rotationally symmetrical structure, and the cross-sectional areas in the flow channel are respectively equal.

[0074] From the above description, it can be seen that cross-sections of the same shape and area are provided in the flow channel to limit the chaotic flow of liquid. After the chaotic liquid flows through a certain length of the flow channel, the flow direction of the liquid tends to be stable; at the same time, the cross-section of the flow channel is set to a rotationally symmetrical structure to facilitate the liquid to flow smoothly into the liquid outlet channel.

[0075] Furthermore, guide ribs are provided in the flow channel, and the guide ribs are arranged perpendicular to the liquid outlet direction.

[0076] From the above description, it can be seen that guide ribs perpendicular to the liquid outlet direction are provided in the flow channel. The guide ribs have a certain blocking effect on the flow of liquid, which can limit the flow direction of the liquid and keep the flow direction of the liquid uniform; at the same time, the guide ribs can also limit the pressure and flow rate of the liquid flowing into the liquid inlet end.

[0077] Furthermore, a filtering device for reducing liquid pressure and slowing down the flow is provided at one end of the flow channel close to the liquid outlet channel.

[0078] From the above description, it can be seen that when the liquid enters the air from the liquid outlet shape control device, the liquid flow is affected by the pressure change to form turbulence or local high-speed flow; therefore, a filtering device is arranged in the flow channel, and the inlet surface and the outlet surface of the filtering device can form a pressure difference, so that the flow velocity of the liquid remains unchanged and flows smoothly after passing through the filtering device, and at the same time the liquid pressure can be reduced.

[0079] Furthermore, the number of the liquid outlet is at least one, the number of the liquid outlet channel is at least one, and the at least one liquid outlet channel corresponds one-to-one to the at least one liquid outlet.

[0080] Furthermore, a temperature control device is provided at one end of the flow channel close to the liquid inlet end.

[0081] As can be seen from the above description, the temperature control device can be used to keep the liquid at a suitable temperature to meet the needs of the user.

[0086] The guide plate 7 is composed of crossed guide ribs, and the guide plate 7 is perpendicular to the liquid inlet direction and is arranged at one end of the flow channel 2 close to the liquid inlet 1;

[0087] The guide plate 7 limits the flow direction of the liquid and has a blocking effect on the flow of the liquid, so that the liquid tends to have the same flow direction and the same flow speed when flowing in the flow channel, and at the same time, the vortex flow between the guide plate 7 and the filter device 8 can be removed;

[0089] The filter device 8 can generate a large resistance to the liquid, and at the same time form a large pressure difference between the inlet surface and the outlet surface to reduce the liquid pressure and make the liquid flow smoothly; after the liquid passes through the filter device 8, the liquid flows perpendicular to the surface of the filter device 9;
