Description

The intelligent hot water list structure

Technical field the utility model relates to the electronic intelligence water meter, particularly relates to the intelligent hot water list structure.

Background technology intelligent hot water table is installed in the rugged surroundings such as kitchen, bathroom, open air mostly; Hot water gauge is worked under high water temperature condition for a long time and will be ensured the serviceable life in 4 years, and the waterproof and dampproof design ten minutes that therefore reduces electronic devices and components and battery environment for use temperature and whole table is crucial.The PCB mainboard of current intelligent hot water table and battery generally all are to be placed in the gear case; Because the heat transferred of hot water; Temperature in the gear case is higher relatively, and battery and electronic devices and components are worked under hot conditions for a long time like this, and are impaired too early easily; It is serious to cause hot water gauge to reprocess situation, and serviceable life is short.

The technical matters that utility model content the utility model will solve is to avoid the weak point of above-mentioned prior art and proposes that a kind of reliability is high, the intelligent hot water list structure of long service life.

The utility model solve the technical problem and can realize through adopting following technical scheme:

Design, a kind of intelligent hot water list structure of making comprise housing, and gear housing assembly, valve component, pcb board assembly, battery holder assembly and cartridge assemblies in the housing; Said PCB assembly is installed on the interior upper end of said housing, away from gear housing assembly and valve component; Said battery holder assembly also is in outside the gear housing assembly.

Said pcb board assembly comprises PCB mainboard, base, loam cake, PIN pin, PCB card extender and silica gel sealing ring; Said PCB mainboard is positioned in the said base, and silica gel sealing ring places between said base and the loam cake, relends to help the screw locking to incite somebody to action and said PCB mainboard is sealed; Said base and the welding of said PCB card extender are passed in said PCB mainboard and the welding of said PIN pin one end, the said PIN pin other end, and this PCB card extender realizes that through bonding wire and extraneous contact the PCB mainboard and the external world are electrically connected again.

Said battery holder assembly comprises battery box, battery, rubber plug, sealing rubber ring and battery case lid, and mutual adaptive screw and nut; Said battery places in the said battery box, said rubber plug and battery box suitable and place in the battery box near opening part; Said nut is embedded in the central authorities of said rubber plug; Said rubber plug and battery case lid are clipped in the middle said sealing rubber ring; The central authorities of said battery case lid and sealing rubber ring all have and are used for the through hole that said screw passes, and said screw successively passes said battery case lid and sealing rubber ring screws in the said nut again.

Compare with prior art; The technique effect of the utility model intelligent hot water list structure is: 1. battery holder assembly and pcb board assembly are away from thermals source such as gear case assemblies; They needn't be operated in as prior art under the hot environment; Prolong the serviceable life of battery and electronic devices and components effectively, thus the serviceable life of corresponding prolongation intelligent hot water table; 2. adopt the PCB modular construction; The PCB mainboard is equivalent to place in the enclosure-type cavity; And cooperate the PCB card extender to realize being electrically connected with the external world; Avoided the problem that to reprocess the direct sealant pouring and sealing of PCB mainboard in the prior art, guaranteed effectively that promptly PCB can be by water-tight, guaranteed that again the PCB mainboard can be reprocessed utilization; 3. employing battery holder assembly makes battery effectively by sealing and waterproof, and the sealing means of battery case is superior to the sealant pouring and sealing mode of prior art, makes things convenient for the replacing of battery and reprocesses.

Description of drawings

Fig. 1 is the cross-sectional schematic of the utility model intelligent hot water list structure;

Fig. 2 is the perspective exploded view of pcb board assembly;

Fig. 3 is the perspective exploded view of battery holder assembly.

Embodiment is done further to detail below in conjunction with the preferred embodiment shown in the accompanying drawing.

The utility model intelligent hot water list structure, as shown in Figure 1, comprise housing 10, and gear housing assembly 20, valve component 30, pcb board assembly 40, battery holder assembly 50 and cartridge assemblies 60 in the housing 10; Said PCB assembly 40 is installed on the interior upper end of said housing 10, away from gear housing assembly 20 and valve component 30; Said battery holder assembly 50 also is in outside the gear housing assembly 20.

As shown in Figure 2, in the utility model, said pcb board assembly 40 comprises PCB mainboard 41, base 42, loam cake 43, PIN pin 44, PCB card extender 45 and silica gel sealing ring 46; Said PCB mainboard 41 is positioned in the said base 42, and silica gel sealing ring 46 places between said base 42 and the loam cake 43, relends to help the screw locking to incite somebody to action and said PCB mainboard 41 is sealed; Said base 42 and said PCB card extender 45 welding are passed in said PCB mainboard and the welding of said PIN pin 44 1 ends, said PIN pin 44 other ends, and this PCB card extender 45 realizes that through bonding wire and extraneous contact the PCB mainboard 41 and the external world are electrically connected again.Whole pcb board assembly 40 is fixedly connected with said housing 10 by long spiro nail.
