Dissipate, stifled bubble part is provided between above-mentioned inner bag 12 and end cap 13, the stifled bubble part is used to prevent expanded material to the direction of end cap 13 expanding
Dissipate.
It is lost in reduce the installation gap location of heat self installation lid 14 and end cap 13, in the present embodiment, aforesaid operations are opened
The edge of mouth 135 is provided with seal groove 132 towards away from the internal direction of housing 11, and the corresponding seal groove 132 of installation lid 14 is provided with sealed muscle
142, the adaptation of sealed muscle 142 is embedded in seal groove 132, and now the surface of sealed muscle 142 and the trough wall surface of seal groove 132 paste
Close, and then sealed muscle 142 is formed sealing with seal groove 132 and is coordinated, and then avoid heat self installation lid 14 and end cap 13
Installation gap location be lost in, and then improve the heat-insulating property of electric heater 10.
In certain embodiments, in order to further reduce the clipping room clearance flow between heat self installation lid 14 and end cap 13
Lose, above-mentioned seal groove 132 can also be thermally insulated, such as can in above-mentioned seal groove 132 stuffed heat insulated material
Material, i.e., heat-barrier material is filled between the cell wall of above-mentioned seal groove 132 and the surface of sealed muscle 142, on the one hand heat-barrier material increases
Strong sealing effectiveness of the seal groove 132 with sealed muscle 142, is on the other hand also significantly prevented between end cap 13 and installation lid 14
Heat exchange, and then the heat-insulating property of electric heater 10 is further lifted.
It should be noted that above-mentioned heat-barrier material can be heat insulation foam or aeroge composite felt, can also be
The mixture of heat insulation foam and aeroge composite felt.Heat insulation foam or aeroge composite felt have good heat insulation and preservation effect, thus
Heat self sealss muscle 142 can be significantly reduced with being lost at the cooperation of seal groove 132, improve the heat-insulating property of electric heater 10.
Technical solutions of the utility model set sealed muscle by setting seal groove 132 on end cap 13 on installation lid 14
142, the adaptation of sealed muscle 142 is embedded in the seal groove 132, reduces the clipping room between sealed muscle 142 and seal groove 132
Gap, and then reduce heat and be lost in from the installation gap location, improve the heat-insulating property of electric heater 10.
Further, reference picture 5 in the present embodiment, is preferably provided with rotation to Fig. 8 between sealed muscle 142 and seal groove 132
Turn interface arrangment, so, it is only necessary to be arranged on installation lid 14 on end cap 13 in a manner of rotary clamping, without using volume
Outer instrument, both assemblings actually facilitate.Normally, the rotary clamp connection structure is provided with multiple, and the plurality of revotating card binding
Structure is uniformly laid in the circumferential of installation lid 14, to cause the week for installing lid 14 to be reached unanimity along the fixing intensity on end cap 13,
So that the stability maintenance of the two is higher.
Specifically, the rotary clamp connection structure include along the seal groove 132 groove width direction set clip-connecting rod 134,
And the neck 144 being caught in for the clip-connecting rod 134 adaptation on the sealed muscle 142.The neck 144 includes introduction segment
144a and clamping section 144b, wherein, circumferentially extendings of the clamping section 144b along sealed muscle 142；Introduction segment 144a one end and clamping
Section 144b connections, the other end is through side of the sealed muscle 142 away from installation lid 14.During assembling, first by the introduction segment of neck 144
144a is directed at clip-connecting rod 134, then applies pressure to the outer surface of installation lid 14, to cause clip-connecting rod 134 to enter from introduction segment 144a
Enter clamping section 144b, then, installation lid 14 is rotated, clip-connecting rod 134 is caught in clamping section 144b remote introduction segment 144a
Position, you can installation lid 14 is stably installed on end cap 13, assembling it is efficient and convenient.Right the design not limited to this, Yu Qi
In his embodiment, rotary clamp connection structure may also include the first limited block (not shown) for being convexly equipped in the inner surface of seal groove 132 and
The side of self sealss muscle 142 is convex to the second limited block (not shown) of seal groove 132；With the first limited block and the second limited block phase
The mode of dislocation, after the embedding sealing groove 132 of sealed muscle 142, the rotation installation limited block of lid 14 to the second and the first limited block exist
Install and offseted only on the axial direction of lid 14, now, interior table of second limited block with respect to the first limited block closer to installation lid 14
Face, so as to by the second limited block limit installation lid 14 depart from end cap 13, realize both this by rotary clamping fix.
In order to prevent above-mentioned clip-connecting rod 134 from being skidded off out of neck 144, installation lid 14 is avoided to be come off from end cap 13, it is above-mentioned
The one end of clamping section 144b away from introduction segment 144a is provided with fixing groove 145, and fixing groove 145 coordinates with clip-connecting rod 134, now by
In the limitation of fixing groove 145, clip-connecting rod 134 will not skid off out of neck 144 easily, and then ensure installation lid 14 and end
The reliability that lid 13 connects.
Further, reference picture 7, in order that installation lid 14 can be more firmly secured on end cap 13, the court of end cap 13
The extension of operation aperture 135 is provided with fixed part 133, and fixing hole 133a is offered on fixed part 133；14 corresponding fixing hole of lid is installed
133a offers mounting hole 143, and installation lid 14 is fixed on end cap 13 so that fastener passes through.It is it is understood that above-mentioned
In rotary clamp connection structure, it is set to be rotated relative to end cap 13 by rotating installation lid 14, and then can realize and fix installation lid 14
On end cap 13, now installation lid 14 has rotates so as to install what lid 14 departed from from end cap 13 in the opposite direction relative to end cap 13
Trend, in order to which further installation lid 14 is clamped securely on end cap 13, prevent that install lid 14 rotates relative to end cap 13 again,
The installation corresponding fixing hole 133a of lid 14, which offers the fastener such as mounting hole 143, screw, pin, can sequentially pass through mounting hole 143
With fixing hole 133a, rotated with preventing to install lid 14 relative to end cap 13.
In addition, in the present embodiment, reference picture 9, in order to strengthen the rigidity of end cap 13, reinforcement 131 is provided with end cap 13.
Wherein, reinforcement 131 is preferably disposed to end cap 13 towards the side of inner bag 12, to avoid reinforcement 131 from being exposed outside, so as to drop
The probability that low dust etc. deposits on the outer surface of end cap 13.
Specifically, the ring-type muscle 131a of reinforcement 131 including multiple circumferentially extendings along end cap 13 and multiple along end cap
13 strip muscle 131b, strip muscle 131b that radially extend intersects with ring-type muscle 131a, with strengthen end cap 13 circumferentially and radially
The ability of anti-deformation of both direction.Similarly, the plurality of ring-type muscle 131a is preferably set along the radially outward uniform intervals of end cap 13
Put, multiple strip muscle 131b are then preferably laid along the circumferential uniform intervals of end cap 13.
Preferred embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model,
Every equivalent structure change under inventive concept of the present utility model, made using the utility model specification and accompanying drawing content
Change, or directly/be used in other related technical areas indirectly and be included in scope of patent protection of the present utility model.
