Bowl cover 20 includes lid 21 and is arranged at the switch valve 22 on this lid 21, and lid 21 is provided with One delivery port 211, delivery port 211 is for being poured out by the liquid within cup 10.Switch valve 22 For controlling delivery port 211 on off state, this switch valve 22 includes sealing-plug 221, closeouts 222 And first elastic component 223.

Sealing-plug 221 is connected with rim of a cup thread seal, such as in Fig. 2 to Fig. 4 example shown, and sealing-plug 221 is cylindrical, its excircle is provided with external screw thread, and rim of a cup is provided with internal thread, sealing-plug 221 Coordinated by internal and external threads with between rim of a cup, and sealing ring can also be set between the two, close to improve Envelope effect.Sealing-plug 221 has fluid passage 2211, the outlet of this fluid passage 2211 and delivery port 211 connection, say, that this fluid passage 2211 be for the liquid within cup 10 is poured out to Delivery port 211.

Closeouts 222 can be slidingly arranged at sealing-plug the most between the first position and the second position On 221, and formed between this closeouts 222 and seal and be tightly connected.It is to say, this closeouts 222 is (as shown in Figure 4,5) that can slide up and down on sealing-plug 221, and the position of top is One position, and the position of lower section is the second place, and in sliding process, closeouts 222 and sealing All the time being to maintain sealing state between plug 221, the liquid in cup 10 is to pass through closeouts 222 And the gap between sealing-plug 221.

First elastic component 223 is arranged between closeouts 222 and sealing-plug 221, so that closeouts 222 It is maintained at primary importance.Such as utilize the compressive state of the first elastic component 223, provide for closeouts 222 Active force upwards, so, can make closeouts 222 be in primary importance.As preferably, This first elastic component 223 can use compression spring.

When closeouts 222 is positioned at described primary importance, this closeouts 222 enters with fluid passage 2211 Interruption-forming seals, and connects with cup 10 isolating the entrance of liquid barrier passage 2211.When closeouts 222 When being positioned at the described second place, this closeouts 222 separates with the entrance of fluid passage 2211, so that liquid The entrance of passage 2211 connects with cup 10.

It is to say, closeouts 222 is for blocking fluid passage 2211 entrance so that fluid passage 2211 connect with cup 10 and block, to realize the open and close of lid 21 upper water-out mouth 211.Tool For body, this closeouts 222 is when primary importance, and closeouts 222 just can liquid for plugging body passage 2211 Entrance so that the liquid in cup 10 cannot flow into fluid passage 2211, so, now Delivery port 211 on lid 21 is then in closed mode, namely can not pour out in cup 10 Liquid.And closeouts 222 is when being positioned at the second place, the entrance of this closeouts 222 and fluid passage 2211 Being separate, the entrance of fluid passage 2211 is in opening-wide state, now, as long as toppling over cup 10, Liquid in this cup 10 can flow in fluid passage 2211, and by fluid passage 2211 from lid Delivery port 211 on body 21 flows out, and so, the delivery port 211 on lid 21 now is then in Open mode, namely can pour out the liquid in cup 10.

Actuator 30 includes that horizontal pivotable connection and is positioned at above closeouts 222 on sealing-plug 221 Wheel shaft 301, circumferentially fixed eccentric wheel 302 on wheel shaft 301, drive eccentric wheel 302 with wheel shaft 301 The impeller 303 rotated between the 3rd position and the 4th position, and do not having impeller 303 to get involved Time make eccentric wheel 302 and wheel shaft 301 be maintained at the second elastic component of the 3rd position.It is, wheel shaft 301 It is horizontally set at above closeouts 222, and can rotate, when wheel shaft 301 rotates, wheel shaft 301 On eccentric wheel 302 then along with wheel shaft 301 synchronous axial system, impeller 303 is then for live axle 301 rotations, and then drive eccentric wheel 302 to rotate between the 3rd position and the 4th position, such as may be used To make impeller 303 move along the direction being perpendicular to wheel shaft 301 by the hand of people pressure pressure, enter And promote the eccentric wheel 302 on wheel shaft 301 to turn to the 4th position, when removing the pressure to impeller 303 Power, then eccentric wheel 302 and wheel shaft 301 can recover to the 3rd position under the effect of the second elastic component.

When eccentric wheel 302 is positioned at described three position, closeouts 222 is at the work of the first elastic component 223 It is maintained at primary importance under with.When eccentric wheel 302 is positioned at four positions, eccentric wheel 302 forces first Elastic component 223 compresses, so that closeouts 222 moves to the described second place.

It is to say, the 3rd position is initial position, when eccentric wheel 302 is positioned at three positions, promote Part 303 does not apply the active force rotated to eccentric wheel 302 or wheel shaft 301, correspondence, eccentric Wheel 302 does not produce the effect of power to the closeouts 222 of lower section, or the power produced is not enough to allow closure Part 222 moves (namely moving downward) to the second place, so, closeouts 222 now is to maintain Inlet seal closure with fluid passage 2211, the delivery port 211 on lid 21 the most now It it is closed mode.And when impeller 303 is to eccentric wheel 302 or the active force of wheel shaft 301 applying rotation, Make eccentric wheel 302 move to the 4th position from the 3rd position, then eccentric wheel 302 is to closure below Part 222 produces the active force moved to the second place (the most downward), so, closeouts 222 from Open the entrance of fluid passage 2211 so that the entrance of fluid passage 2211 connects with cup 10, now, Delivery port 211 on lid 21 is i.e. transferred to opening by closed mode.

The thermos cup provided according to the present invention, uses eccentric wheel 302 to drive closeouts 222 to move up and down Fluid passage 2211 entrance on sealing-plug 221 is opened and closed by mode, thus realizes lid The air of the opening and closing of the delivery port 211 on 21, its simple in construction, easy to operate, meanwhile, interior Portion's air residual is few, and sealing effectiveness is more preferable.

In one embodiment of the invention, also including lock piece 40, this lock piece 40 includes being arranged at The toggle switch 401 at lid 21 top and be arranged at bottom lid 21 and can be with toggle switch 401 along horizontal stroke To the STATEMENT OF FEDERALLY SPONSORED 402 of motion between lock position, unlocked position, locking position.It is to say, dial Dynamic switch 401 is slidably arranged on lid 21, it is possible to stir between three positions, and correspondence STATEMENT OF FEDERALLY SPONSORED 402 is fixing with toggle switch 401 to be connected, can be with toggle switch 401 three positions Between stir and between lock position, unlocked position, locking position move.Such as in Fig. 6, Fig. 7 Shown in, left side is locking position, and centre is unlocked position, and right side is lock position.

This STATEMENT OF FEDERALLY SPONSORED 402 has shell fragment 4021 and lock part 4022, and wheel shaft 301 has holding section 3011 With limiting section 3012.When toggle switch 401 is positioned at lock position, holding section 3011 and shell fragment 4021 Relatively, and holding section 3011 turns to the 3rd position with eccentric wheel 302 and engages with shell fragment 4021, with Wheel shaft 301 is limited to the 4th position.

As shown in Figure 6, right positions gets final product lock position, when this position, if wheel shaft 301 now position In the 3rd position, the most do not rotate and be in initial position, then the holding section 3011 on wheel shaft 301 Just be in just to state with the shell fragment 4021 in STATEMENT OF FEDERALLY SPONSORED 402, when this just to, if wheel shaft 301 are driven by impeller 303 and to turn to the 4th position from the 3rd position, then in wheel shaft 301 rotation process, Holding section 3011 is close to the front surface of shell fragment 4021 and forces shell fragment 4021 to deviate, until holding section 3011 front surfaces crossing shell fragment 4021 and offset (the most mentioned above with the rear surface of shell fragment 4021 Engage with shell fragment 4021), now, owing to the conflict effect of shell fragment 4021 with holding section 3011 makes Wheel shaft 301 can not rotate backward, it is, wheel shaft 301 rests on the 4th position and can not be back to Three positions, now, cancel the active force of impeller 303, and 301, wheel shaft so rests on the 4th position, So, fluid passage 2211 keeps connecting with cup 10, and delivery port 211 is held open state, the most just Being, when this lock position, to unclamp after clicking impeller 303, delivery port 211 can be constantly in Open mode.

When toggle switch 401 is positioned at described unlocked position, holding section 3011 is horizontal with described shell fragment 4021 To dislocation, to release the restriction that described wheel shaft 301 is rotated.

As shown in Figure 6, centre position gets final product unlocked position, when this position, due on wheel shaft 301 Holding section 3011 and the shell fragment 4021 in STATEMENT OF FEDERALLY SPONSORED 402 stagger certain position the most in the axial direction, so, Now, when impeller 303 promotes wheel shaft 301 to be turned to four positions by the 3rd position, holding section 3011 All the time it is not in contact with shell fragment 4021, so rotating shaft can not be locked, therefore, if now withdrawn from The active force of impeller 303, then wheel shaft 301 recovers to the 3rd position under the effect of the second elastic component, It is, when this unlocked position, only delivery port 211 just can be made at Continued depression impeller 303 Open, unclamp impeller 303 then delivery port 211 and close.

When toggle switch 401 is positioned at described locking position, described limiting section 3012 and described lock part 4022 offset, so that described wheel shaft 301 is limited to described 3rd position.
