Detailed Description
Example, see figure 1: the thermos bottle inner plug switch comprises a switch body 60, the switch body 60 is matched with the upper opening of the thermos bottle 100, and an outer cover 200 is arranged on the upper opening of the thermos bottle 100 and positioned outside the switch body. That is, generally, the switch body 60 is responsible for sealing the upper opening of the thermo jug 100, and the outer lid 200 plays roles of decorating, protecting the inner switch body 60, and also serving as a cup. The switch body 60 may be used in various ways, such as, for example, a switch body 60 that can be pressed to allow water to exit and pressed again to seal.
Further speaking:
the switch body 60 has a metal heat-conducting plate 51 at the lower part, an integrated temperature display module 52 at the upper part and a button cell 53 at the lower part. The button cell 53 provides electric power to the integrated temperature display module 52, and the metal heat-conducting strip 51 is connected to the integrated temperature display module 52 through at least 1 metal heat-conducting wire 54. The integrated temperature display module 52 may be an integrated temperature display module that is lighted when touched, and the metal heat-conducting strip 51 and the metal heat-conducting wire 54 are used to conduct the temperature inside the thermo jug 100, and then the temperature information is displayed on the integrated temperature display module 52. In addition, the integrated temperature display module 52 and the button cell 53 should be properly treated so that they do not come into contact with water.
Optimizing:
the switch body 60 includes an outer tub 10. The outer tube 10 includes an upper tube 11, a middle tube 12, and a lower tube 13. The upper barrel 11 has an outer diameter and an inner diameter both larger than those of the middle barrel 12 so that the upper barrel 11 and the middle barrel 12 are connected by an upper transition step 14. The middle cylinder 12 has an outer diameter and an inner diameter both larger than those of the lower cylinder 13 so that the middle cylinder 12 and the lower cylinder 13 are connected by a lower transition step 15. That is, from the top down, the diameter of the outer cylinder 10 is reduced in a stepwise manner, and the upper transition step 14 and the lower transition step 15 are preferably horizontal.
A sealing sleeve 20 is arranged in the inner cavity of the upper barrel 11, the upper part of the sealing sleeve 20 is provided with a containing cavity 21 with an upward opening, and the bottom of the containing cavity 21 is provided with a transition through hole 211. The sealing sleeve 20 can be clamped in the inner cavity of the upper barrel 11 by means of interference fit.
The accommodating chamber 21 is provided with a fitting cover 30, an upper fitting chamber 31 is provided at an upper portion of the fitting cover 30, and a fitting through hole 311 is provided at a bottom of the upper fitting chamber 31. Similarly, the fitting cover 30 can be clamped in the accommodating cavity 21 by interference fit, and the fitting through hole 311 and the transition through hole 211 are aligned.
The outer circumferential surface of the middle cylinder 12 is provided with external threads 121. Correspondingly, the upper opening of the thermo jug 100 is provided with an internal thread matching with the external thread 121.
The lower part of the lower cylinder 13 is closed to have a sealing bottom 131. The lower side of the sealing bottom 131 is provided with a lower assembly chamber 1311 which is opened downwards.
The lower transition step 15 is provided with an annular seal groove 151, and a seal gasket 40 is arranged in the annular seal groove 151. Correspondingly, a sealing step should be provided in the upper opening of the thermo jug 100 below the internal thread, and the sealing step and the sealing washer 40 can seal the thermo jug after being pressed tightly.
The button cell 53 is fixed on the lower side of the integrated temperature display module 52 by means of fastening or sticking, and the integrated temperature display module 52 is fixed in the upper assembly cavity 31. For example, the integrated temperature display module 52 is fixed in a housing, and the lower portion of the housing is provided with at least 3 claws for clamping the button cell 53. The metal heat-conducting plate 51 is fixed in the lower assembling chamber 1311 by means of clipping or adhesion. The metal heat conducting wire 54 passes through the middle of the sealing bottom 131 from bottom to top in a sealing fit manner, and then passes through the transition through hole 211 and the fitting through hole 311 in sequence to be connected with the integrated temperature display module 52. Of course, the power line for supplying power to the metal heat conducting strip 51 may pass through the matching through hole 311 and the transition through hole 211 from top to bottom in sequence, and then pass through the middle of the sealing bottom 131 in a sealing fit manner to connect with the metal heat conducting strip 51. The sealing fit through the sealing bottom 131 may be, but is not limited to, the metal heat conducting wire or the corresponding power line is inserted into a rubber sleeve, and the middle portion of the sealing bottom 131 is provided with a small hole, and the rubber sleeve is inserted into the small hole.
Further optimization:
a transparent waterproof cover 70 is fixed to an upper opening of the upper assembly chamber 31 by screwing or clipping. That is, the upper opening of the upper assembly chamber 31 is sealed by the transparent waterproof cover 70, so that the integrated temperature display module 52 and the button cell 53 have good waterproof property.
The upper part of the upper barrel 11 is fixed with a main sealing cover 80 with an upper part sealed and a lower part opened by screw connection or clamping connection, and the upper part of the main sealing cover 80 is transparent or semitransparent. That is, the assembly cover 30, the integrated temperature display module 52, and the button cell 53 are further sealed in the outer tub 10 by the main sealing cover 80, and the waterproof performance is further enhanced.
A collar 90 is fixed to the lower portion of the sealing bottom 131, and the collar 90 is fitted to the metal heat-conducting plate 51. For example, the sealing bottom 131 is provided with a ring-shaped fixing groove around the lower assembly chamber 1311, the collar 90 is clamped in the fixing groove, and the inner edge of the collar 90 is clamped on the edge of the metal heat-conducting strip 51, so as to further prevent the metal heat-conducting strip 51 from falling off.
Thus, when in use, the switch body 60 is slightly rotated to slightly separate the sealing gasket 40 from the sealing step of the thermos, and then water can be poured outwards; the switch body 60 is rotated again, and the switch body 60 can be removed. Meanwhile, each component is simple in assembly, so that the power line and the metal heat conducting wire can be conveniently penetrated and arranged. Namely, the integrated temperature display module and other parts can be conveniently prevented from being waterproof, and the displayed temperature is accurate.
In the above embodiment, the integrated temperature display module 52 may be a commercially available integrated temperature display module, for example, a model D L C06 available from dlong electrical appliances ltd, guangkang, zhejiang, and the connection between the integrated temperature display module and the button cell 53 and the metal heat conductive wires 54 is described in the specification, meanwhile, the metal heat conductive wires 54 may be copper wires, and the metal heat conductive sheet 51 may be a bowl made of stainless steel.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
