Description

Gas-liquid mixing and gas dissolving device, flushing assembly and intelligent closestool

Technical Field

The utility model relates to a bathroom product, in particular to a toilet bowl.

Background

Bubble water is increasingly favored by consumers because less water is discharged within the same water discharge time and no stinging sensation is generated during use, the bubble water is softer and the cleaning strength of the water is stronger. However, the existing bubble water foaming mode generally adopts natural air suction, and an air pump is added to provide air for a water outlet end so as to generate bubble water, or a water pump is added to pressurize so as to increase the water flow speed and generate negative pressure so as to suck air and generate bubble water; the air and water are separated under the condition that the air bubble water in the natural air suction mode is mostly, the water and the air are not fully mixed, the influence of water pressure is large, the water-air mixing effect is poor, the water is not soft enough when in use, and the flushing strength is weak when the water contacts with the surface of the stain, so that the stain is not easy to clean; the way of adding the air pump and the water pump is complex in structure and high in cost. In addition, because of different regions, the water pressure of all regions of the country is different, the water pressure of some regions is low, the water pressure of some regions is relatively high, and many bubble water structures can form good bubble water effects at high water pressure, but the bubble water effects at low water pressure are poor.

Referring to fig. 1 to 4, this embodiment provides a gas-liquid mixing and gas dissolving device, including: a housing 1; the housing 1 has an opening 11 for inlet air and inlet water, and a mixing chamber 12 communicating with the opening 11, the mixing chamber also having an outlet 13 for bubble water;

a spiral unit 2 is arranged in the mixing cavity 12; the screw unit 2 is provided with a first screw sub-unit 21 and a second screw sub-unit 22 along the length direction of the mixing chamber 12, and the screw directions of the first screw sub-unit 21 and the second screw sub-unit 22 are different.

According to the gas-liquid mixed gas dissolving device, under the condition that the water inlet pressure is less than 0.12MPa, the water flow of the linear motion in the pipe body can be changed into the water flow of the spiral motion, and as the spiral directions of the first spiral subunit 21 and the second spiral subunit 22 are different, the mixed liquid rotates and shears, the contact liquid level between gas and water is increased, the greater the contact liquid level between gas and water is, the higher the efficiency of gas in water is, namely the shorter the time of gas in water is, the greater the quantity of gas in water is, and bubbles are continuously cut down and distributed in water in the rotation and shearing processes of a plurality of chambers. Therefore, the gas-liquid mixing effect can be well realized under the low-pressure state.

It should be noted that, in this embodiment, the first spiral subunit 21 and the second spiral subunit 22 are taken as examples, and of course, a third spiral subunit may be added, which belongs to simple replacement in this embodiment, and will not be described again.

In this embodiment, the spiral directions of the first spiral sub-unit 21 and the second spiral sub-unit 22 are different, so that the mixed solution can be rotated and sheared. However, in order to maximize the effect of the rotation and shearing motion of the mixed liquor, the spiral directions of the first spiral sub-unit 21 and the second spiral sub-unit 22 are preferably set to be at an angle of 90 °.

To further increase the effect of the rotation and shearing movement of the mixture, the first spiral sub-unit 21 and the second spiral sub-unit 22 form a cycle. While the screw unit 2 has three periods along the length of the mixing chamber 12. Thus, the mixed liquid is circularly rotated and sheared, the contact liquid level between the gas and the water flow is increased, the greater the contact liquid level between the gas and the water is, the higher the efficiency of the gas in the water is, namely, the shorter the time of the gas in the water is, the greater the quantity of the gas in the water is, and the bubbles are continuously cut to be smaller and are uniformly distributed in the water in the rotating and shearing processes of a plurality of chambers. The number of the periods may be increased or decreased as needed, and is not limited to 3 periods in the present embodiment.

In this embodiment, the end surface 23 of the spiral unit 2 facing the opening 11 is used to divide the passing water flow and air flow into two and then enter the first spiral sub-unit 21. For this purpose, a side end 23 of the screw element 2 facing the opening 11 is located on the central axis of the mixing chamber 12. When the water and gas mixture enters the gas dissolving device, the water and gas mixture is firstly divided into two parts by the end face 23 of the spiral unit 2, then enters the first spiral subunit 21, changes the water flowing in the pipe body in linear motion into water flowing in spiral motion, and then enters the second spiral subunit 22, and the transverse shearing of the water flowing is realized because the rotation directions of the two spiral subunits form an included angle of 90 degrees.

The gas-liquid mixing and gas-dissolving device can be applied to a flushing assembly of an intelligent closestool, so that the flushing assembly can also jet out bubble water when the water pressure is low, and the use experience of a user is improved.

The foregoing is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto, and any person skilled in the art will be able to make insubstantial modifications of the present utility model within the scope of the present utility model disclosed herein by this concept, which falls within the actions of invading the protection scope of the present utility model.
