In a place where there is no household power source, the secondary battery 55 is connected to the power source connecting terminal 51 so that the control circuit 19 operates in the secondary battery operating state and at least the electric pump 14 is driven and controlled to control the content liquid. Since it can be poured out electrically, the advantages and disadvantages of the past are eliminated, and moreover,
Dispensing will be automatic where there is no household power supply, making it more convenient and easier to use than a manual pump.

The heater 3 is used even when the secondary battery 55 is used.
It is possible to control the temperature of b etc. by driving,
The power consumption is large and the life of the secondary battery 55 is short,
Considering that the secondary battery 55 is used for a short time, it can be said that it is preferable not to drive the heaters 3a and 3b during the use of the secondary battery 55 as in the first embodiment.

Further, since the power source connection terminal 51 is shared by the household power source and the secondary battery 55, it is not necessary to provide a dedicated power source connection terminal for each, and the external structure of the body 6 does not become complicated, and the usual structure is not required. It will be as simple as anything. Moreover, connecting the secondary battery 55 to the power connection terminal 51,

When the electric pump 14 is driven by the secondary battery 55, for example, when the voltage across the secondary battery 55, which is fully charged to about 4.8 V, is 2.4 V or more, the control circuit 19 side. It is assumed that the pump drive voltage can be increased to about 6V, and when there is a rapid voltage drop that does not allow the full content liquid of 3.8 liters to be discharged, assuming that the life of the secondary battery 55 is 4.8V to 2. By setting a set voltage at a certain intermediate point up to 4 V, for example, 3.6 V, and adding the time required for passing 3.6 V while the pouring switch 21 is turned on, It is possible to determine whether or not the battery 55 has reached the end of its life.

FIG. 4 shows a comparison between the voltage change V1 when the new secondary battery 55 is used and the voltage change V2 when the secondary battery 55 having a near-lifetime is used. If the voltage change V1 in the case of the secondary battery 55 is 3.6 V
It takes a long time T2 from the start of driving the electric pump 14 to reach V.sub.2, whereas the voltage change V2 in the case of the secondary battery 55, which is near the end of its life, reaches 3.6 V in a short time T1.

The discriminating means 71 of the first embodiment discriminates the life of the secondary battery 55 by the time when the voltage across the secondary battery 55 reaches the set voltage from the start of driving the electric pump 14 as described above, and the life of the secondary battery 55 is determined. When it reaches, the LED lamp 25 is turned on to display it.

The flowcharts of FIGS. 5A and 5B show an example of such control.

Then, it is determined whether the voltage across the secondary battery 55 is the initial voltage of 4.8 V in the cordless mode.

If the cordless mode is not set and the initial voltage is 4.8 V, the process directly returns.
If the initial voltage is not 4.8 V, the process proceeds to determine the life of the secondary battery 55, and the electric pump 14 is driven and the content liquid is discharged as the discharging switch 21 is turned on. . During this period, counting of the elapsed time T is started, and at the same time, shifting to (b) of FIG. 5, it is judged whether the voltage across the secondary battery 55 has passed 3.6 V, and 3.6 V is determined.
The value of the count T is the life value T _END
If it is less than the value, the process returns as it is, and if it is more than the life value T _END , the LED lamp 25 is turned on to display the life.

In this way, since it is displayed whether or not the secondary battery 55 has reached the end of its life, the user can accurately know when to charge the secondary battery 55, and the secondary battery 5 can be displayed without delay.
5 can be charged to eliminate waste of work due to too early charging, and to prevent abnormal use such as insufficient operation of the electric pump due to too late charging.

Further, since the secondary battery 55 has the magnetic plug 55a which is a connecting portion directly connected to the power source connecting terminal 51, it can be directly connected to the power source connecting terminal 51 when the secondary battery 55 is used. , Rechargeable battery 5 for connection
No case for accommodating 5 is required, which simplifies the configuration.
Further, the secondary battery 55 has a charging plug 55c that appears and disappears, and can be charged by being connected to an outlet that is a supply port of a household power supply in a state where the plug 55c is projected. However, charging can also be done by other methods.

(Second Embodiment) FIG. 6 shows a second embodiment of the present invention. In the second embodiment, as shown in FIG. 6, a primary battery 155 is used. The number of primary batteries 155 used may be one.

As described above, the secondary power supply means 65 of the second embodiment connects the primary battery 155 to the power supply connection terminal 73 different from the power supply connection terminal for supplying the power from the household power supply to the control circuit. In order to supply electric power to the electric motor of the control circuit and other direct current circuits, the power source for the home and the primary battery 155 use separate power supply connection terminals. Since the control circuit including the power supply circuit when using the battery can be fixedly provided, it is not necessary to switch the control circuit depending on which one is used, and the circuit configuration is simplified. However, the second embodiment
In the above, a secondary battery may be used instead of the primary battery 155.

As the primary battery 155, a commercially available dry battery may be purchased and replaced whenever the life of the primary battery 155 is reached, and the primary battery 155 can be used easily for a long period of time.

Further, since the primary battery 155 is housed in the battery case 72 and connected to the power supply connection terminal 73, connection with the power supply connection terminal 73 can be achieved easily and in a single operation even if there are a plurality of them. It Even when the primary battery 155 is used, it is preferable to determine the life and display when the life is reached.

(Third Embodiment) FIGS. 7 to 9 show a third embodiment of the present invention. In the third embodiment, as shown in FIG. 7, the secondary power supply means 65 is a power supply for converting the alternating current from the power supply connection terminal 51 with the household power supply of the control circuit 19 into direct current to supply power to the direct current circuit part. Circuit 81 and electric pump 1
4, the charging circuit 82 and the secondary battery 55 are connected so that the secondary battery 55 is closer to the electric pump 14 than the charging circuit 82 is.

As a result, the secondary power supply means 65 uses the power supply from the household power source to operate the charging circuit 82 as necessary when the household power source of the control circuit 19 is connected and used. While the secondary battery 55 is being charged, it can be used normally by driving the electric pump 14 via the secondary battery 55, and in a place where there is no household power source, no electric power is supplied from the household power source. Electric power is supplied from the charged secondary battery 55 to the electric pump 14 to drive it, so that the content liquid can be automatically poured out in a place where there is no home power supply. Therefore, there is an advantage that the work of attaching and detaching the secondary battery 55 is not necessary depending on the difference between using the household power source and using the secondary battery 55 as in the first embodiment. The secondary battery 55 may be attached or detached only when it reaches the end of its life and is replaced.
