Installation avoids the globality of cleaning machine tank wall from being destroyed in this way, have the advantages that will not leak, however the design is also with defect,
When particularly repairing heating tube, need to go out to remove entirely by the cleaning machine parts in heating tube, workload is bigger, Er Qiejing
Frequently with this maintenance mode, it can also reduce cleaning machine other component and be damaged, the problem of service life reduction, brief introduction increases cleaning and sets
Standby use cost.
Invention content
Goal of the invention：It is a kind of rational in infrastructure, easy to maintenance present invention aims in view of the deficiencies of the prior art, providing
And sealing effect effectively prevent well the electric heater unit of cleaning machine tank wall leak.
Technical solution：A kind of electric heater unit of the present invention, including heating tube, the heating tube is equipped with interior gear
Circle and outer cover, the inner shield ring are fixed on the inside of the tank wall of cleaning machine, and the outer cover is located on the outside of the tank wall of cleaning machine, described interior
Between baffle ring and outer cover there is inflatable seal washer, on the inner shield ring there is heating tube to install fastener, the expansion type
Seal washer and the inserting hole for covering the reserved installation fastener outside, the installation fastener are pierced by after outer cover by lock-bit part
It is locked, heating tube is made to compress inflatable seal washer while being fixed on cleaning machine, blocks and plants electric heating on cleaning machine tank wall
The reserved interporal lacuna of pipe；The electric contact of the heating tube is connect across outer cover with power supply unit.
Further, the sealing effect for the raising present apparatus, prevents cleansing medium from being revealed by heating tube mounting hole, described
Inflatable seal washer includes gasket layer and expansion type blocks layer, and the expansion type blocks layer and is located on the inside of the gasket layer,
Internal diameter is matched with inner shield ring.
Further, inflatable seal washer the being integrated molding structure.
Further, the inflatable seal washer is elastic material；On the one hand the high resiliency of the material is utilized, is being pressed
Good deformation is generated when tight, the heating tube mounting hole on tank wall is blocked, on the other hand using the thermal expansion performance of the material, into one
Step ensures the sealing to heating tube mounting hole, prevents cleansing medium from revealing.
Further, as the present invention more excellent embodiment, it is described installation fastener be bolt, the lock-bit part be with
The nut of bolt matching.
Further, the heating tube and outer cover being integrated molding structure.
Further, heating tube mounting hole is effectively blocked for ease of inflatable seal washer, the inner shield ring is fixed on
The inside of cleaning machine tank wall.
Advantageous effect：（1）The present apparatus by inner shield ring, inflatable seal washer, outer cover and install fastener connection,
Realize cleaning machine heating tube is external, when heating tube need repairing replacement when, maintenance personal can be real outside cleaning machine
Now to heating tube repair, replace, convenient, efficiently, the not other component of damage cleaning machine, improve cleaning machine indirectly uses the longevity
Life；（2）By setting inflatable seal washer between inner shield ring and outer cover in the present apparatus, integral sealing leak stopping effect is improved
Fruit, expansion type blocks the design of layer and on the one hand utilizes the high resiliency of the material in inflatable seal washer, is generated when being compacted
The heating tube mounting hole on tank wall is blocked in good deformation, on the other hand using the thermal expansion performance of the material, is further ensured that pair
The sealing of heating tube mounting hole, prevents cleansing medium from revealing.
Description of the drawings
Fig. 1 is the overall structure of the explosion figure of apparatus of the present invention；
Fig. 2 is the right view of apparatus of the present invention；
Wherein：1st, heating tube, 2, inner shield ring, 21, fastening bolt, 22, nut, 3, outer cover, 4, inflatable seal washer,

Specific embodiment
Technical solution of the present invention is described in detail below by attached drawing, but protection scope of the present invention is not limited to
The embodiment.
Embodiment 1：A kind of electric heater unit, including heating tube 1, heating tube is equipped with inner shield ring 2 and outer cover 3, inner shield ring 1
It is fixed on the inside of the tank wall of cleaning machine, outer cover 3 is located on the outside of the tank wall of cleaning machine, has expansion type between inner shield ring 2 and outer cover 3
Seal washer 4 has heating tube fastening bolt 21 on inner shield ring 2, is reserved on inflatable seal washer 4 and outer cover 3 and prohibit solid spiral shell
The inserting hole of bolt, fastening bolt 21 are locked by nut 22 after being pierced by outer cover, are compressed while heating tube 1 is made to be fixed on cleaning machine
Inflatable seal washer 4 blocks the reserved interporal lacuna that electrothermal tube is planted on cleaning machine tank wall；The electric contact 11 of heating tube passes through outer
Lid 3 has on outer cover 3 and connects electric collet 5, and heating tube 1 is connect by connecing electric collet 5 with power supply unit.
In this equipment, inflatable seal washer 4 includes gasket layer 41 and expansion type blocks layer 42, and expansion type blocks 42, layer
In 41 side in gasket layer, internal diameter is matched with inner shield ring；Inflatable seal washer is elastic material, using integrated forming technique
