In other embodiments, the side wall of the fluid chamber 4 extends out of a length of tubing (not numbered) with an end provided as an opening 41 and one end of the negative pressure return tube 2 is sleeved inside or plugged outside the tubing. Optionally, a first seal 51 is mounted between the outer wall of the negative pressure return tube 2 and the inner wall of the tube; alternatively, the first seal 51 is mounted between the inner wall of the negative pressure return tube 2 and the outer wall of the tube. This embodiment is not illustrated, and will not be described in detail here.

In this embodiment, please continue to refer to fig. 3 to 5, the structure further includes a spray head 11. The nozzle 11 is connected to one end of the high pressure intake pipe 1, and the nozzle 11 is disposed towards the opening 41 of the fluid chamber 40, and the other end of the high pressure intake pipe 1 passes through the negative pressure return pipe 2 and then is connected to the accommodating chamber 300.

In this embodiment, please continue to refer to fig. 3 to 5, the liquid-gas inlet-outlet integrated pipe includes a second sealing member 52, and two sides of the second sealing member 52 are respectively and hermetically connected to the connection position of the high-pressure inlet pipe 1 and the negative pressure return pipe 2.

For this purpose, a second seal 52 is mounted between the outer wall of the high-pressure intake pipe 1 and the inner wall of the negative-pressure return pipe 2 to prevent leakage from this location.

Alternatively, the second seal 52 is an annular seal member, such as an annular seal ring or an annular gasket, disposed around the outer wall of the high-pressure intake pipe 1. And the second sealing member 52 may be a rubber member, a silicone member, or waterproof EVA (foam), etc.

In the present embodiment, please continue to refer to fig. 2 to 5, the nozzle 11 extends to the inside of the fluid chamber 40, so as to avoid the problem of insufficient flow rate of the cooling liquid and gas, and then is directly discharged through the transfer tube 6, thereby preventing the heat exchange efficiency from being reduced.

In the present embodiment, please continue to refer to fig. 3 and 4, the adapter tube 6 and the negative pressure return tube 2 are disposed to intersect, and the connection position of the negative pressure return tube 2 and the adapter tube 6 is disposed in a sealing manner.

Alternatively, with continued reference to fig. 3, the adapter tube 6 and the negative pressure return tube 2 intersect to form a T-shape, specifically, the adapter tube 6 communicates with the intermediate position of the negative pressure return tube 2.

In this embodiment, the liquid-gas inlet and outlet integrated pipe further comprises a pressure pump 7, and the pressure pump 7 and the high-pressure inlet pipe 1 are mutually communicated and used for conveying the cooling liquid gas in the accommodating cavity 300 to the spray head 11 through the high-pressure inlet pipe 1 and then spraying the cooling liquid gas. Wherein the pressure pump 7 may be arranged inside the water tank 30, i.e. in the receiving chamber 300.

In this embodiment, the liquid-gas inlet and outlet integrated tube further comprises a vacuum pump 8 and a collecting bin body 23, wherein an input end of the vacuum pump 8 is communicated with the adapter tube 6, so that the adapter tube 6 and the negative pressure return tube 2 form a relative negative pressure state, and then the cooling liquid-gas in the fluid cavity 40 is discharged to the external collecting bin body 23. Wherein the pressure pump 7 may be arranged inside the collecting bin body 23.

In this way, the pressure pump 7 sprays the cooling liquid and gas into the fluid chamber 40 at a high speed, the cooling liquid and gas contacting the fluid chamber 40 is a mixture of liquid and particles, and the heat transferred by the side wall of the fluid chamber 40 can cause the mixture of liquid and particles of the cooling liquid and gas to be vaporized by heating, wherein the speed of vaporizing the particles by heating is increased, that is, the heat absorption efficiency of the cooling liquid and gas is increased. After the cooling liquid and the gas are vaporized and absorb heat, the cooling liquid and the gas are condensed on the inner wall of the fluid cavity 40 in a particle form until the cooling liquid is converged into liquid, and then the cooling liquid and the gas in the fluid cavity 40 are discharged to the external collecting bin body 23 through the vacuum pump 8, so that continuous refrigeration and heat dissipation of the electronic module are realized. In addition to this, it should be appreciated that the present application, while reducing the connection locations of the outflow conduit and the fluid chamber 40, is provided with a first seal 51 at the corresponding connection location. However, in an alternative scenario, the first sealing element 51 may not be provided at this connection point, i.e. although there is a small gap at this connection point, the liquid and gas inside the fluid chamber 40 is discharged through the negative pressure return pipe 2 due to the suction effect of the vacuum pump 8, avoiding leakage of liquid and gas.

In summary, the liquid-air inlet and outlet integrated pipe utilizes the inner cavity space of the part of the negative pressure return pipe 2 as the assembly space of the inflow pipeline, changes the structure that the original inflow pipeline and the outflow pipeline are mutually communicated with the fluid cavity independently, reduces the connection position of the pipeline and the fluid cavity, thereby reducing the water leakage probability and improving the heat dissipation efficiency.

Further, explanation will be made taking an example in which the liquid-gas inlet-outlet integrated pipe is covered above the electronic module, and the opening 41 is provided in the bottom side wall of the fluid chamber 4. In other words, when the liquid level of the cooling liquid gas inside the fluid chamber 40 submerges at least part of the opening 41, the liquid cooling liquid gas is quickly discharged to the collection bin 23 after passing through the negative pressure return pipe 2 and the transfer pipe 6.

With continued reference to fig. 4, a second embodiment of the liquid-gas inlet-outlet integrated tube of the present application will now be explained in detail.

The second embodiment is similar to the first embodiment except for the above structure, and the details are not repeated here.

With continued reference to fig. 5, a third embodiment of the liquid-gas inlet-outlet integrated tube of the present application will now be explained in detail.

The pressure pump 7 and the vacuum pump 8 are respectively and electrically connected with the electronic module, the liquid-gas inlet-outlet integrated pipe is arranged in the shell, and the fluid cavity 4 of the liquid-gas inlet-outlet integrated pipe is in contact with the electronic module.

In some electric appliances, the layout of the negative pressure return pipe 2 and the adapter pipe 6 is set according to the structural layout in the actual electric appliance, and is not limited to the several forms in the above embodiments, but may be shaped, and is not limited to the examples.

In some electrical appliances, the negative pressure return pipe 2 and the switching pipe 6 are flexible pipelines, and clamping positions for clamping the negative pressure return pipe 2 and the switching pipe 6 are arranged on corresponding shells.

In some electrical appliances, the collection bin 23 and the receiving cavity 300 are located outside the housing of the electrical appliance.

In addition, those skilled in the art will appreciate that the use of the liquid-air inlet and outlet integrated tube structure is not limited to the field of heat dissipation. The structure that the high-pressure inflow pipe 1 and the negative pressure return pipe 2 of the application are combined not only can be combined with the fluid cavity 40 of the application to form a liquid-air in-out integrated pipe structure for radiating the electronic module, but also can be applied to a device for heating a certain part. The corresponding fluid chamber 40 is used for conducting heat, the high-pressure inflow pipe 1 is used for conveying liquid and gas with heating function, and the negative pressure return pipe 2 discharges the liquid and gas with heating function.

Specifically, the fluid chamber 40 serves as a receiving space for cleaning the mop, the high-pressure inflow tube 1 for conveying cleaning liquid, and the negative pressure return tube 2 for discharging sewage. This structure not only realizes liquid discharge through the vacuum pump 8, but also reduces the connection position of the outflow pipe and the fluid chamber, i.e., reduces the probability of opening the opening in the fluid chamber 4. Correspondingly, the corresponding sealing measures at the connecting positions are reduced, and the liquid-gas leakage probability of the whole device is improved.

In an optional scene, the liquid-gas inlet and outlet integrated pipe structure can also be applied to chemical production devices for realizing the reaction of certain chemical substances;
