Abstract

The utility model relates to a water bucket fitting head capable of preventing deformation of a water bucket of a water dispenser. An air inlet is arranged on the opening of the water bucket of the water dispenser or in the position slightly lower than the opening. The water bucket fitting head raises the position of the air inlet so as to reduce the water level pressure difference inside the bucket; the air inlet and a passage are added onto the water bucket fitting head, so that the water dispenser has smooth air intake and normal water flowing; and water passages are uniformly distributed, so that the air pressure inside the water bucket is uniform. Such comprehensive measures prevent deformation of the water bucket with thin wall thickness.

Description

Intellectual head

Technical field

The utility model relates to a kind of intellectual head that can improve the water pot for drinking water machine distortion.

Background technology

At present, known traditional water dispenser water inlet portion structure intellectual head and smart seat is formed or be made of intellectual head and the whole smart seat that smart seat synthesizes.Principle is barreled drinking water that water dispenser uses (an or water-purifying tank), pour into the smart seat at machine top, complying with the inner intellectual head of smart seat cooperates with the ingenious of intelligent lid of water bottle oral area, intelligent lid in the intellectual head jack-up water bottle in the smart seat, the interior water of water bottle is entered in the machine by the blasthole of intellectual head, until cold water tank, go out cold water or the diversion cans of flowing through, enter hot-water cylinder from the cold water tap, utilize the pressure principle that hot water is flowed out from the hot water tap.After water is filled cold water tank and hot-water cylinder, the continuous inflow of water afterwards, water level rises and has sealed the air inlet of intellectual head bottom, water descends the general who has surrendered to form pressure less than external pressure again in bucket in this moment bucket, water descends more in leading to, and pressure more little (being that so-called negative pressure is big more) in the bucket is worked as at last to the water level face, the height pressure that the bucket internal pressure adds inner bucket water is during with the pressure balance of atmosphere, and water is in decline in the bucket.

Traditional similar 18.9 liters bucket PC blow molding, wall thickness is thicker, can resist in the bucket because the inside and outside differential pressure " negative pressure " brought in the bucket, but some similar 10L also, and 5L but is difficult to resist this kind " negative pressure " with the bucket of PET blow molding and can deforms.At this moment Tong smaller volume, rise in the inner bucket water position, and the air pressure in the bucket increases, and a bucket internal gas pressure adds that the height pressure difference of water will be greater than atmosphere outside pressure, and water continues to flow out.So circulation causes water to overflow from water dispenser at last, even bucket may take place falls down, and causes water dispenser internal short-circuit or near other electrical short-circuit, the life security that jeopardizes the user.

The utility model content

In order to overcome the distortion of bucket; reduce the inside and outside pressure reduction of bucket; decompose partial pressure; technical problem to be solved in the utility model provides and a kind ofly can not only solve the defective that the water fountain bucket air inlet is smooth, water yield does not reach industry standard; and can reduce inner bucket water and press; reduce the influence that the bucket wall is subjected to negative pressure simultaneously, the distortion of bucket is had the intellectual head of better protective effect.

Because of existing intellectual head normally has passage or the groove that 2 to 3 circular holes or both sides fluting contact with water in the bucket on the top of diversion column, the bottom of diversion column is that chassis opening or intellectual head has several through holes, formed a gas channel that joins with the external world with the air-vent of water dispenser, be raised to bottom the smart seat this moment when water level, the external air inlet channel sealing, it is less that water level rises, the height pressure difference that the bucket internal gas pressure adds inner bucket water just with the external pressure dynamic balance, inner bucket water no longer flows out.The bottleneck of bucket and intellectual head bottom also has an appointment 3 to the difference in height of 4CM in fact.

The technical scheme that its technical problem that solves the utility model adopts is: at the bottleneck of the corresponding water fountain bucket of intellectual head or be provided with air inlet on the lower position slightly.

Preferably, intellectual head of the present utility model has additional air inlet on diversion column, and the position of air inlet is near the bottleneck of corresponding water fountain bucket.

Preferably, intellectual head of the present utility model evenly offers a plurality of circular ports or square opening or other irregularly-shaped holes on its bottom disc, offer circular port or slotted eye near its top or top.

Preferably, intellectual head of the present utility model is provided with the gas shutoff plate in its bottom, seals the opening of intellectual head diversion column bottom, makes current go up orifice flow from garden, intellectual head bottom dish and goes out, the turbulent flow that produces when preventing water under the bucket.This gas shutoff plate can adopt button bit or screw thread or welding manner to link to each other with intellectual head.

Adopt the technical solution of the utility model, at the bottleneck of the corresponding water fountain bucket of intellectual head or after being provided with air inlet on the lower position slightly, when the water level of water dispenser is sealed air inlet and is stopped from external feed stream, if the bucket middle water level is identical when having intellectual head now with use, it is poor that the pressure of the interior air of bucket will increase the level pressure of 3-4CM, be equivalent to increase about 300 to 400Pa air pressure, both the bucket wall also with little 300 to 400Pa air pressure, has the improvement of getting well to preventing the ladle body distortion with the inside and outside differential pressure that bears.

The utility model is offered circular port or square opening or other irregularly-shaped holes on the intellectual head bottom disc, on diversion column, set up air inlet, enlarge aisle spare so first with the external pressure exchange, second increase the approach of air inlet: have only the air-vent air inlet originally, now from also carrying out tonifying Qi between bucket and the smart seat.The utility model is big according to atmospheric pressure, passage is up straight, can reduce air pressure loss principle and increase through hole at the intellectual head top, can make original gas channel obtain best replenishing, revise the back air-flow reaches close top from the top sidepiece air inlet, water flows out from circular hole on the lower side, and air inlet and exhalant canal are very unimpeded.

Existing intellectual head bottom is an opening, because it is straight-through with bucket, be easy to when discharging water again because the inertia of current, water flow velocity will be very fast, and other position, hole is because be the side water outlet, and water flow velocity is slow partially, in bucket, will produce turbulent flow like this, and then make a barrel internal gas pressure instability, and local distortion takes place, make bulk strength influenced.After the utility model increased the gas shutoff plate, the water in the bucket can only evenly flow into the diversion basin along the equally distributed through hole of intellectual head bottom disc from the through hole of the bottom of mozzle, belongs to the laminar flow phenomenon, and air is even with pressure in the bucket like this, is not easy to be out of shape.

The utility model can better improve water fountain bucket pressurized in use, reaches the purpose that the thin partially bucket of protection wall thickness prevents its distortion; Can use in the bucket of different materials, the tonifying Qi effect is better than traditional intellectual head, and the water dispenser tap can reach the industry requirement of 1.2L/min fully, and the bucket more weak to intensity has protective effect, and be simple in structure.
