Abstract

A liquid delivery system comprising a base unit ( 2 ) comprising a liquid inlet in an upwardly facing surface, a liquid duct leading from the inlet to a liquid outlet above the liquid inlet; a pump for pumping the liquid from the inlet to the outlet; a motor to drive the pump; and a shroud extending upwardly in a manner which surrounds the inlet, the system further comprising a vessel ( 1 ) received within the shroud in an inverted configuration with its outlet lowermost and in communication with the fluid inlet, the vessel ( 1 ) having a refill opening ( 20 ) towards the end opposite to the outlet.

Description

Liquid conveying system

The present invention relates to a kind of liquid conveying system.

Specifically, the present invention relates to applicant's the base unit of early applying for the liquid conveying system of description among the GB 0820981.9.

This liquid conveying system comprises base unit, and the refill unit of the material that splendid attire is to be allocated is assemblied in this base unit to be inverted structure, and namely the outlet of refill unit is at lowermost end.Base unit comprises: be arranged in the liquid inlet to upper surface, fluid pipeline leads to the liquid outlet that is positioned at the top, liquid inlet from entrance; The pump of pumping liquid from the inlet to the outlet; The motor of driving pump; And to surround the upwardly extending guard shield of mode of entrance, guard shield has top edge.This base unit is known as " described type " in the back.

In the use, the lowermost end of refill unit is provided with a valve.When refill unit was mounted to described base unit, the socket that projects upwards of encirclement liquid inlet was opened the valve in the refill unit, thereby allowed liquid to flow to pedestal from refill unit.

The invention provides a kind of alternative that recharges this system.

According to the present invention, liquid conveying system comprises the base unit of described type, it is characterized in that this system further comprises being inverted structure and is received in container in the guard shield, the outlet of described container is positioned at bottommost and is communicated with the liquid inlet, and described container has the opening that recharges towards the end relative with its outlet.

In use can be positioned at the existence that recharges opening on the top of container, allow user's refill container and no longer need it is removed from pedestal, more must not dispose described container and with a new replacement it.

In GB0820981.9, described container is a bottle that has valve at opening, and described valve is resiliently biased and seals outlet, and is opened when being arranged in inserting pedestal and opens the flow passage that out enters described pedestal from container.Also can provide such valve in the present invention.But because do not need to remove described container in recharging process, therefore described valve not necessarily.Therefore, as an alternative, can control flowing from outlet without valve.In this case, in order to prevent making dirty, then described container can fill by first empty insertion pedestal, and perhaps pedestal can fallen to be placed on the top of described container before its assembling, and the described container that then reverses makes it enter mode of operation.

In its simplest form, described container can be to have calyculus to receive the lining of liquid.The removable cap of purpose can be deposited, transmit and recharge to described lining with being useful on.Perhaps, described container can have the ampuliform structure that self can selectively cut out by closing element.This can take the self-closing valve form, perhaps takes can to separate with bottle or can connect with bottle in some way the form of the removable cap of (for example, by slide mechanism or hinge).

With reference now to the embodiment of accompanying drawing description according to system of the present invention,, in the accompanying drawings:

Fig. 1 is the profile according to the distributor with bottle that only is used for the GB0820981.9 that background technology contains;

Fig. 2 introduces in the distributor but the sectional block diagram of the refill unit of unassembled Fig. 1 also;

Fig. 3 is the front perspective view according to the first embodiment of system of the present invention; And

Fig. 4 is the front perspective view according to the second embodiment of system of the present invention.

Before describing the present invention, the first as a setting operation of the distributor with refill unit of technology introduction GB0820981.9.

Described distributor is the non-hand-held dispenser that generally is applicable to family expenses.Distributor mainly is for distributing soap lye, but liquid or the semi liquid state product (having ideally the viscosity larger than water) that also can be used for distribute other, for example hand lotion, skin cream, moisturiser, face cream, shampoo, shower cream, the foam of washing one's hands, shaving cream, hand cleanser, toothpaste, acne treatment frost, surface cleaner or sanitizer alcohol gel for example.

Described distributor comprises two major parts, i.e. container 1 and base unit 2.Described container 1 is provided with the reservoir of storing liquid to be allocated and as the base unit 2 that is assembled to described below.

Described base unit has interface 3, and liquid is dispensed to this interface 3 from refill unit.Interface 3 and distributing pipe 4 fluid connections.Pump 5 operates that selectively metering liquid is pumped dispensing head 6 along distributing pipe 4.

Described base unit has infrared transmitter 7A, and it is used for launching the infrared beams that arrives receiver 7B by window 8, with existing of the hand that detects near user distributor.Control circuit is to making a response to start described pump from the signal of proximity transducer.Illustrated sensor is truncated beam sensor (break beam sensor), but also can be reflection sensor.Although what provide is infrared sensor, but any known proximity transducer for example capacitance sensor all can be used.Device can be by network supply or powered battery.

With reference now to Fig. 2 describe in more detail the bottle 1 and base unit 2 between interface.

Base unit 2 comprises guard shield 10, and the major part that guard shield 10 surrounds bottle is with protection and support bottle.Socket 11 is outstanding at the base portion of guard shield 10.Has a plurality of castellation section 13 at the end face of socket.O shape ring sealing ring 14 centers on socket 11 below castellation section 13.

When refill unit 1 is placed when entering base unit 2, socket 11 enters the ring exit 15 in the bottom of refill unit 1, and O shape ring sealing ring 14 seals facing to this ring exit.So socket overcomes the effect of elastic bias components 17 and lifts outlet valve element 16, thereby opens the flow passage that enters base unit.Two pressure-reducing valves 18 allow air to enter bottle when liquid is assigned with.

According to refill unit of the present invention as shown in Figure 3, this refill unit has identical shape with the refill unit of describing in the past, but it also can have different shapes.This refill unit can have valve element 16 and/or one or more pressure-reducing valve 18.But these for its operation not necessarily.

Refill unit 1 has the opening of recharging 20 at the top, the described opening 20 that recharges is selectively closed by cap 21, and described cap 21 is attached to the top of described bottle by flexible hinge 22.

Refill unit 1 can be filled liquid or sky.If be full of liquid, just need removable lid.If do not need such lid, base unit 2 is reversed into structure as shown in Figure 3 and was placed on the top of housing before can normal operating with being squeezed at whole assembly ideally.

Perhaps, refill unit 1 can be empty, can place it in simply in the base unit 2 with orientation shown in Figure 3 in this case.If bottle is empty, perhaps when full bottle need to recharge, the user opened simply cap 21 and new liquid is poured into refill unit 1, thereby continues to use described device according to normal mode.

Perhaps, as shown in Figure 4, the whole top section of refill unit 1 can be removed, thereby described refill unit has calyculus rather than the structure of ampuliform as shown in Figure 3.The cup-shaped refill unit can be closed with being assemblied in described cap (larger than cap 21) on filler cells.
