Description

A kind of mute type liquid feed device

Technical field

The utility model relates to a kind of liquid feed device, and the mute type liquid feed device that especially a kind of noise is minimum is applicable to the feed flow that water dispenser, air humidifier etc. install.

Background technology

Existing atomizing humidifying performance machine, its structure comprises bucket, bucket base and atomising device, bucket is arranged on the bucket base, the delivery port of this bucket links to each other with the water inlet of atomising device by drain pipe, by atomising device pure water is atomized, steam is emerged by exhaust outlet, realizes the humidification to air.This kind atomizing humidifying performance machine, pure water enters atomising device after by drain pipe, after water outflow in the bucket is a certain amount of, form negative pressure in the staving, when the need air inlet, air is also entered by this drain pipe and finishes additional air in the bucket, can form a series of bubble simultaneously, be accompanied by the sound that rings take place, especially influence the people at night between have a rest.

The bucket of existing water dispenser comprises a staving, and staving one end has a delivery port.Water in the bucket flows into the cold water chamber and the hot hydroecium of water dispenser respectively by this delivery port, for drinking.But because this kind bucket has only a delivery port, this delivery port is also used as air inlet promptly as water outlet usefulness.In the process of discharging water; water in the bucket continuously outflows, and the air pressure in the bucket reduces, and reaches certain pressure; air promptly sucks bucket from this delivery port; because the bucket domestic demand forms certain negative pressure, air could suck, and each amount of air drawn is also more relatively; take a breath with the form of a string air bubble through regular meeting; can send the sound of " rumble, rumble " during ventilation through regular meeting, especially at night, " rumble " sound that sends during pouring can disturb other people rest.

Summary of the invention

The utility model provides a kind of mute type liquid feed device at the deficiency that prior art exists, and this installs as the feed flow function, and not only noise is little, and is little to environmental disturbances, and economical and practical.

The technical solution adopted in the utility model is:

A kind of mute type liquid feed device, it comprises an airtight staving, and this staving bottom is provided with a drain pipe, it is characterized in that described staving bottom is provided with an air inlet pipe in addition, and the bottom of this air inlet pipe is higher than the bottom of drain pipe, and staving top is stretched at the top of air inlet pipe.

The exit of staving bottom is provided with a lid, and drain pipe and air inlet pipe are arranged on the lid.

The upper port of drain pipe is concordant with the lid end face, and the lower port of air inlet pipe is concordant with the lid bottom surface.

Staving top can also be provided with a liquid injection port, and the outlet passageway of steam is left at the staving middle part.

The utility model has following advantage compared to existing technology:

Quiet liquid feed device of the present utility model is applicable to that water dispenser supplies water, also can be used for the water supply of air wetting machine and be the feed flow of other device, this liquid feed device is owing to added an air inlet pipe on the next door of drain pipe, continuously outflow in the process of staving at liquid, this air inlet pipe is also replenished air constantly, in time eliminated the negative pressure that produces in the staving, avoided concentrating and replenished the noise that air brings.Because this air inlet pipe stretches in the staving and near the top, and general air inlet pipe is exposed liquid level, and the air that enters staving does not directly pass through liquid, so can not send the noise of " rumble, rumble ", the noise jamming at night has not just existed yet simultaneously.

The utility model design is ingenious, simple in structure, and production cost is low, is fit to the needs of modern high-quality family life, after applying, can improve the grade of Related product, can be subjected to liking of consumer surely.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing:

Embodiment one: water dispenser

As shown in Figure 1, quiet liquid feed device of the present utility model, it comprises an airtight staving 1, this staving 1 bottom is provided with an opening 2, opening 2 places are provided with a water outlet drain pipe 4, this drain pipe 4 in bucket, the bucket outside respectively leave a bit of length.Be provided with an air inlet pipe 5 with this drain pipe 4 is parallel, these air inlet pipe 5 upper ends are stretched in the staving 1, and staving 1 is stretched out in the lower end, and opening 2 places of staving 1 bottom are provided with a lid 3, and drain pipe 1 all is sleeved on this lid 3 with air inlet pipe 5.The bottom of this air inlet pipe 5 is higher than the bottom of drain pipe 4, and staving 1 top is stretched at the top of air inlet pipe 5, is advisable with the height that exceeds high liquid level (HLL), with convenient ventilation.The upper and lower port of air inlet pipe 5 is higher than the upper and lower port of drain pipe 4 respectively, and two pipe upper port are in staving 1, and lower port is outside staving 1, to make things convenient for fluid and air inlet.The top of drain pipe 4 is low as far as possible, and the height at top is barrel height of interior final residue liquid, and the bottom that the bottom is lower than air inlet pipe 5 gets final product operate as normal, and diameter is unsuitable too small when liquid viscosity is big, avoids liquid tension to influence fluid.

The liquid feed device of this structure can be used as the water supply bucket of drinking machine, because when discharging water, water continuously outflows the negative pressure of formation and is replenished by air inlet pipe 5 timely air inlets, and air is to enter staving by air inlet pipe 5, ventilation is the direct water body in bucket not, so can not send the sound because of vibrating water body, also be that we are difficult for hearing even a sound is arranged, can not produce interference.The lower end of air inlet pipe 5 is higher than the lower end of drain pipe 4 among the design, after can guaranteeing that like this water flows out, the air of water surface top can enter bucket and replenish, when air inlet was flooded in the rising of the liquid level outside the bucket, air can not enter in the bucket, along with the reduction of inner bucket water face, the negative pressure of air can stop the continuation of water to be flowed out in the bucket, water can not continue to flow out when reaching balance, reaches the purpose of control liquid level, has played the effect of automatic switch thus.After underwater outside the bucket was reduced to the air inlet mouth of pipe, air inlet exposed liquid level, and the outer air of bucket flows in the bucket because of negative pressure in the bucket, and the water in the drain pipe 4 can flow out to supply with continuously to be drunk.

Embodiment two: humidifier

As shown in Figure 2, for making liquid feed device of the present utility model be suitable for devices such as atomizing humidifying performance machine, opening 2 places in staving 1 bottom are provided with a lid 3, drain pipe 4 is arranged on the lid 3 with air inlet pipe 5, the upper port of drain pipe 4 is concordant with lid 3 end faces, and the lower port of air inlet pipe 5 is concordant with the bottom surface of lid 3.Can also add a liquid injection port 6 on staving 1 top, can avoid liquid to enter air inlet pipe 5, reducing intake resistance, and reduce final residue liquid.The outlet passageway 7 of steam is left at staving 1 middle part, so that steam is emerged.

This practical mute type liquid feed device not only can be used for above-mentioned water dispenser water supply, humidifier and supply water, the device that can also be used for other continuous liquid supply, this device is the outer liquid level of control staving automatically, automatically stop feed flow after being higher than certain altitude, can continue to begin feed flow when being lower than certain altitude again.
