Description

Rotary shower head and coffee machine

Technical Field

The utility model belongs to a water supply technology of beverage equipment, and particularly relates to a rotary shower head capable of uniformly outputting water flow and a coffee machine.

Background

The drip filter type coffee maker is used for outputting hot water into a filter tank and dissolving coffee powder (such as a material bag) in the filter tank to make a coffee beverage. In the prior art, water flow sprayed to the filter tank is not uniform, so that the coffee is soaked in inconsistent time, and the taste of the coffee is influenced. In particular, the water in the water tank of the coffee machine can generate a part of steam after being heated, and the existence of the steam can aggravate the phenomenon that the water flow sprayed to the filter tank is uneven.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problems and provide a rotary shower head capable of uniformly outputting water flow and a coffee machine, and aims to overcome the defects that the existing drip filter type coffee machine has uneven water flow sprayed to a filter tank, so that the coffee is not soaked for a uniform time, and the taste of the coffee is influenced.

In order to achieve the purpose, the rotary shower head comprises a shell and is characterized in that: the shell is provided with an inner cavity, a water inlet communicated with the inner cavity and a plurality of water outlet holes, and a rotating body which rotates by means of water inflow from the water inlet is arranged in the inner cavity so as to uniformly distribute the water inflow from the water inlet to the water outlet holes. When the water outlet device works, water is fed into the inner cavity through the water inlet and is discharged outside through the water outlet holes, and the rotating body rotates by means of the water fed from the water inlet, so that the water is uniformly discharged from the water outlet holes. Moreover, even if the hot water contains a small amount of steam, the interference of the steam can be overcome by the rotation of the rotating body, and the uniform water outlet can be realized.

In order to promote the rotating body to rotate flexibly, a convex shaft and a shaft hole are separately arranged on the rotating body and the shell, and the convex shaft is positioned in the shaft hole to realize rotating fit.

In order to make compact structure, with the volume control of rotatory gondola water faucet at reasonable size, especially make the inflow from the water inlet impact the rotator and rotate, the shell is the platykurtic, the inner chamber has the chamber end and lateral wall, the water inlet is located the lateral wall, a plurality of apopores are located at the bottom of the chamber.

In order to avoid that the inner ports of the water outlet holes form water films due to the surface tension of water, the bottom of the rotating body is provided with a water scraping part which scrapes the inner ends of the water outlet holes when rotating, and the water scraping part can destroy the water films formed at the inner ports of the water outlet holes, so that the water in the inner cavity can smoothly flow out through the water outlet holes.

In order to achieve reasonable and effective water film scraping, the rotating body comprises at least two spokes distributed radially, and the lower edges or/and the bottom surfaces of the spokes form the water scraping part.

In order to make water flow out evenly through the rotation of the rotating body, the rotating body comprises a surrounding edge and a hub part positioned in the center of the surrounding edge, the spokes are connected between the surrounding edge and the hub part, and the hub part is in running fit with the shell. The water is evenly distributed to each water outlet hole through the rotation of the spokes.

In order to provide a flow-through space for the water, water channels are formed between the spokes. Or, the spokes are provided with water through holes. When the spokes are provided with water flow holes, the rotating body is provided with a bottom surface, a spiral water tank is arranged on the upper side of the bottom surface, the upper ends of the water flow holes are positioned on the bottom surface of the spiral water tank, and the water flow from the water inlet is uniformly distributed to the water outlet holes through the diversion of the spiral water tank.

Because the water flow flows from the edge of the rotating body to the center of the rotating body in the spiral water tank, the water flow flows to the center of the rotating body by inertia, and in order to enable the water flow through holes to uniformly distribute the flowing water, the longer the distance between the water flow through holes and the center of the rotating body is, the larger the hole diameter is, and the shorter the distance between the water flow through holes and the center of the rotating body is, the smaller the hole diameter is.

In order to cause the rotating body to rotate, the radial edge of the rotating body is provided with a water flushing part which is impacted by water inlet from the water inlet to cause the rotating body to rotate.

In order to avoid that the centrifugal action caused by the rotation of the rotating body enables the water pressure distributed around the cavity to be larger, the water pressure distributed at the center of the cavity to be smaller and therefore the water outlet holes are uneven in water outlet, the distances between the water outlet holes and the center of the inner cavity are larger and smaller, and the distances between the water outlet holes and the center of the inner cavity are smaller and larger, so that the uneven water pressure is balanced, and the flow rate of the water outlet holes is even.

In order to avoid the water flowing out of the water outlet holes from converging together, the water outlet holes extend to the lower part of the shell through the pipe parts, and the water outlet of each water outlet hole can independently flow downwards.

To facilitate assembly, the housing includes a shell having a slot and a cover that fits over the shell and covers the slot, the slot defining the internal cavity.

When the rotary shower head is applied to a coffee machine, water can uniformly flow out, so that the coffee is soaked for the same time, and the good taste is ensured. The coffee machine comprises a main machine and a coffee cup, wherein the main machine is provided with a hot water supply waterway, and is characterized in that: the main machine is also provided with the rotary shower head, and the water inlet of the rotary shower head is connected with the hot water supply waterway.

In order to facilitate the operation and the coffee brewing, the top of the main machine is provided with a turnover cover, the lower side of the turnover cover is provided with a filter tank, and the rotary shower head is positioned between the turnover cover and the filter tank.

For cleaning, the filter tank is detachably mounted, and the rotary shower head is connected with the hot water supply waterway in a laterally movable manner.

The rotating body is arranged in the inner cavity of the shell, and when the water outlet device works, the rotating body rotates by means of water inlet from the water inlet so as to uniformly distribute the water inlet to the water outlet holes and enable the water outlet holes to uniformly discharge water. The rotary shower head is applied to the coffee machine, so that water can be uniformly discharged, the coffee is soaked in the same time, and the good taste of the coffee is ensured.
