Further, leakage inspector includes detection plate 20 and the first electrode 21 being arranged at intervals in detection plate 20
With second electrode 22, electrode bar 23 is provided with first electrode 21 and second electrode 22.
In the present embodiment, water purifier includes housing 10 and detection plate 20, is examined by being set in the bottom of case of water purifier 10
Drafting board 20, and detection plate 20 includes first electrode 21 and second electrode 22, wherein, first electrode 21 and second electrode 22 are side by side
It is arranged at intervals, electrode bar 23 is provided with first electrode 21 and second electrode 22.When only minimal amount of water droplet is in water purification
During device bottom, when water droplet is not enough to connect two detecting electrodes, water leakage fault state will not be triggered, it is to avoid leakage inspector
Erroneous judgement.After leak occurs in water purifier and recovers, with regard to that water purifier can be made to exit leak after only the water inside machine need to be discharged
Malfunction, dries the moisture in detection plate 20 without taking water purifier apart, therefore the water purifier in the present embodiment is going out
It can quickly resume work after existing water leakage fault, reduce after cost.Or, in other embodiments, first electrode 21 and
Two electrodes 22 can also arrange compartment of terrain by the way of at an angle, can specifically be set according to actual conditions.Wherein, leak
Water detection means is connected with the control device 100 of water purifier, and by the Bluetooth data transmission device 107 that is set in housing with
Exterior terminal transmits signal, when leakage inspector detects water leakage fault, sends the signal to the control dress being attached thereto
100 are put, control device 100 is connected by Bluetooth data transmission device 107 with mobile phone terminal, and send this signal to mobile phone terminal,
To remind user to handle in time.
It is highly preferred that water purifier also includes the fault detect for being connected and being connected with leakage inspector with control device 100
Device 101.Further, when water purifier is in running status, whether the monitoring water purifier of failure detector 101 there is event
Barrier, can be by data storage to data storage device 103.In particular, often occur because failure caused by leak in water purifier,
Therefore in the present embodiment, failure detector 101 is connected with leakage inspector, when failure detector 101 is detected Lou
Water detection means is sent after water leakage, is immediately sent failure to control device 100, is then sent to what is be connected with water purifier
Cellphone subscriber end, to remind user to be handled in time.Certainly, failure detector 101 can also detect other failures, than
Such as the problems such as water purifier short circuit occurred inside or service interruption, control can be sent a signal to by failure detector 101
Device 100.
On the basis of a upper embodiment, leakage inspector also includes the alarm being connected with detection plate 20.In order to anti-
Only in the case that user is not successfully connected with water purifier by Bluetooth data transmission device, user can not timely receive failure
Alarm is additionally provided with the detection plate of leakage inspector in information, the present embodiment, for when there is water leakage fault, and
When send alarm to remind user to be handled.
Further, reference picture 3 and Fig. 4, the quantity of electrode bar 23 is multiple, and multiple electrodes rod 23 is in the He of first electrode 21
It is uniformly distributed in second electrode 22.By the way that multiple electrodes rod 23 is evenly distributed in first electrode 21 and second electrode 22,
So that when leak does not exist together outside stream from the bottom plate of housing 10, being evenly distributed on the electrode in first electrode 21 and second electrode 22
Rod 23 can also detect leak, so as to expand the detection range of leak water detdction component.Preferably, electrode bar 23 in the present embodiment
Preferably metal bar.
Reference picture 5, in order to ensure that between the electrode bar 23 in first electrode 21 and second electrode 22 water droplet will not be formed, electricity
Spacing between pole rod 23 is unsuitable too small, it is preferable that the electrode bar 23 in first electrode 21 and the electrode bar in second electrode 22
The distance between 23 be 10~15mm.Because in the case that spacing is too small between electrode bar 23, even if aggregation will be caused seldom
Water it is also possible that being turned between two electrode bars 23 in first electrode 21 and second electrode 22, it is possible to create water leakage situation
Erroneous judgement.Therefore in the present embodiment, the distance between electrode bar 23 on electrode bar 23 and second electrode 22 in first electrode 21
Be set to be not less than 10mm, wherein it is optimal apart from design load be 13mm, under this distance value, if water is accumulated into water
Drop, can accurately detect leak, if simply remained, some are water stain, will not be first electrode 21 and second electrode 22
On electrode bar 23 connect.
Further, in order to prevent leak and moisture be discharged between the bottom surface of back casing 10 and electrode bar 23 into still shape
Into water droplet, and make connection between electrode bar 23, the present embodiment will be designed to there is one between the bottom plate of electrode bar 23 and housing 10
The structure of fixed gap, the erroneous judgement of water leakage situation is prevented with this.Preferably, the scope control in gap is between 1~2mm, because
Once occur the situation of leak for the water on water purifier bottom plate, at once can discharge the water of bottom plate, the water now accumulated on bottom plate
Thickness will not be very big, so the gap between electrode bar 23 and bottom plate is designed between 1~2mm, that is, not result in leak
The erroneous judgement of situation, it also avoid leak really occur due to the excessive situation without detecting in gap.Wherein, between optimal
Gap value is 2mm.
Preferably, it is formed with water route side and filter core side, the bottom plate of housing 10 and is provided with for connecting water route in housing 10
The intercommunicating pore 24 of side and filter core side, intercommunicating pore 24 is positioned close to the position of detection plate 20.In the present embodiment, in order to ensure filter core
When leak occurs for side, the detection plate 20 installed in water route side can also be detected, and connection water route side is set on the bottom plate of water purifier
With the intercommunicating pore 24 of filter core side, and intercommunicating pore 24 is positioned close to the position of detection plate 20, can detect filter core leakage in time
The situation of water.
Further, detection plate 20 is fixed on the bottom of case of water purifier 10 by being arranged on the fixture of the bottom of housing 10,
Detection plate 20 can also be arranged on the bottom of housing 10 by fixture using the either buckle of neck 11 by the cooperation of screw and nut
Portion.The present embodiment is preferred to use the holding detection plate 20 of neck 11, directly can be inserted detection plate using the holding detection plate 20 of neck 11
Enter in neck 11, it is easy for removal and installation.
Further, the water inlet and delivery port of water purifier are arranged in housing, and wherein valve includes being connected with water inlet
Main valve and the auxiliary-valve that is connected with delivery port, delivery port is connected with sterilizing unit (not shown).Housing in the present embodiment
For rectangular-shape, it can be made of metal or ceramics or plastics, the inside of housing is provided with cavity, cavity provided with one or more
