Technical Field

[0001] The invention relates to the technical field of household appliances, in particular to a kettle. Background Art

[0002] The existing kettle comprises a kettle body and a kettle cover. The kettle cover is movably mounted on the kettle body and used to open or close the water inlet. The kettle cover is also usually equipped with a filter cartridge that can enter and exit the kettle body through the water inlet. The filter cartridge is used to accommodate materials that need to be soaked or boiled, such as tea, coffee, and wolfberry.

[0003] For example, the utility model patent "A Safe Electric Kettle" with patent application number CN201822229596.9 (publication number CN210300647U) discloses a safe electric kettle, including a kettle body and a power base, the kettle body including an inner liner for holding liquid, a handle arranged on the side of the inner liner, a bottom cover arranged under the inner liner and a kettle lid arranged above the inner liner, the kettle lid also includes a first kettle lid and a second kettle lid, a mounting hole that passes through the inner liner is formed in the middle of the first kettle lid, the second kettle lid is installed in the mounting hole, and the mounting hole of the first kettle lid is provided with a metal filter cartridge that extends into the inner liner.

[0004] However, for the above-mentioned kettle, when the user replaces the boiling object inside the filter cartridge after opening the lid, the user needs to hold the top of the filter cartridge from above, lift it up and take it out from the water inlet. During this process, the rising steam may very likely scald the user. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a kettle which is convenient for taking and placing a filter cartridge and can reduce the risk of scalding in view of the current status of the prior art.

[0006] The technical solution adopted by the present invention to solve the above technical problems is: a kettle, comprising

[0007] A pot body, which is hollow inside and has an opening at the top;

[0008] A kettle lid, hinged to the kettle body, capable of opening or closing the opening; and

[0009] A filter assembly capable of entering and exiting the interior of the kettle body through the opening;

[0010] The feature is that: a fixing frame is provided on the kettle body;

[0011] The kettle also includes

[0012] A movable frame is mounted on the fixed frame in a manner that it can move up and down relative to the fixed frame, and the filter assembly is detachably mounted on the movable frame;

[0013] A first elastic member is disposed between the fixed frame and the movable frame, and enables the movable frame to always have a tendency to rise away from the fixed frame;

[0014] A second elastic member is disposed between the pot body and the pot cover, and enables the pot cover to always have a tendency to open the opening; and

[0015] A locking assembly, used to lock and unlock the relative positions of the kettle cover and the kettle body;

[0016] In the locked state, the pot cover overcomes the effect of the second elastic member to close the opening and abuts against the top of the filter assembly, so that the movable frame overcomes the effect of the first elastic member and approaches the fixed frame;

[0017] In the unlocked state, the pot lid opens the opening under the action of the second elastic member and releases the contact with the filter assembly, so that the movable frame moves away from the fixed frame under the action of the first elastic member and drives the filter assembly to rise and extend out of the opening.

[0018] In order to lock and unlock the kettle lid, a stopper is provided on the kettle body;

[0019] The locking assembly includes

[0020] A locking seat, which is laterally movable and arranged on the pot cover, and has a locking tongue corresponding to the stopper; and

[0021] A third elastic member is disposed between the pot cover and the locking seat, and can make the locking tongue of the locking seat always have a tendency to move toward the stopper;

[0022] In the locked state, the locking tongue abuts against the lower side of the stopper;

[0023] In the unlocked state, the locking tongue is separated from the stop portion.

[0024] In order to facilitate the driving of the locking tongue, the interior of the pot cover is hollow, the locking seat is arranged inside the pot cover, and the locking seat has a first inclined surface that gradually rises along the moving direction of the locking tongue from the locked state to the unlocked state;

[0025] The locking assembly also includes

[0026] A button is movably disposed inside the pot cover, with a top end exposed outside the pot cover and a bottom end having a second inclined surface abutting against the first inclined surface; and

[0027] The fourth elastic member is arranged between the pot cover and the button, and can make the button always have an upward trend.

[0028] In order to prevent the button from detaching from the pot cover, a limit block is provided on the outer side wall of the lower part of the button. When the button is in a high position, the limit block abuts against the lower part of the top wall inside the pot cover.

[0029] In order to facilitate the processing of the stopper, the edge of the opening is bent and extended inward to form the stopper.

[0030] In order to facilitate the installation of the first elastic member, the fixed frame is provided with a mounting seat, and the mounting seat is provided with a receiving groove for receiving the movable frame. The first elastic member is a compression spring, which is installed in the receiving groove. The two ends of the first elastic member are respectively abutted against the inner wall of the receiving groove and the bottom wall of the movable frame.

[0031] In order to prevent the movable frame from detaching from the fixed frame, a limiting groove intersecting with the accommodating groove is provided on the inner side wall of the mounting seat. The limiting groove is in the shape of a strip and extends along the moving direction of the movable frame. Correspondingly, a limiting protrusion is convexly provided on the outer side wall of the movable frame, and at least a part of the limiting protrusion can be inserted into the limiting groove so as to slide up and down. This also highlights the advantage of setting up a movable frame, because if the movable frame is cancelled and the filter assembly is directly movably installed on the fixed frame, the filter assembly needs to be detachably connected to the fixed frame, and it is impossible to set the above-mentioned limiting protrusion to cooperate with the fixed frame for limiting, so that the highest position of the filter assembly cannot be limited, which will cause the filter assembly to easily detach from the fixed frame.

[0032] In order to facilitate the installation of the second elastic member, the fixing frame is provided with a hinged seat. Correspondingly, a rotating shaft is installed at the rear end of the pot cover, and both ends of the rotating shaft are rotatably connected to the hinged seat. The second elastic member is a torsion spring, which is sleeved on the rotating shaft. The two ends of the second elastic member are respectively abutted against the fixing frame and the pot cover.

[0033] In order to facilitate the loading and unloading of the filter assembly on the movable frame, the filter assembly includes a filter cartridge and a bracket for supporting the top of the filter cartridge. The side of the bracket has a mounting column, and the movable frame is provided with a mounting groove for inserting the mounting column.

[0034] In order to facilitate the removal of the filter cartridge from the bracket, a step hole is opened on the bracket along the height direction for inserting the filter cartridge. The top edge of the filter cartridge is bent outward and extended to form a convex edge, which is limited to the step surface of the step hole.

[0035] In order to facilitate the user to hold the bracket from the side, the edge of the bracket is provided with a support edge extending outward for easy holding.

[0036] In order to improve the stability of the bracket in the locked state, the kettle body is provided with a supporting portion;

[0037] In the locked state, the support edge abuts against the support portion;

[0038] In the unlocked state, there is a gap between the support edge and the support portion for a finger to be inserted from the side.

[0039] Here, the support edge plays two roles: on the one hand, it is convenient for the user to lift the filter assembly upward from the side of the bracket through the support edge; on the other hand, it can share the gravity of the filter assembly in the locked state to avoid stress concentration on the mounting column of the bracket.

[0040] Compared with the prior art, the advantages of the present invention are: through the cooperation of the fixed frame, the movable frame, the first elastic member, the second elastic member and the locking assembly, in the locked state, the kettle lid overcomes the action of the second elastic member to close the opening and abuts against the top of the filter cartridge, so that the movable frame overcomes the action of the first elastic member and approaches the fixed frame; in the unlocked state, the kettle lid opens the opening under the action of the second elastic member and releases the abutment against the filter cartridge, so that the movable frame is away from the fixed frame under the action of the first elastic member, and drives the filter cartridge to rise and extend out of the opening; when it is necessary to replace the boiled object inside the filter cartridge, the user only needs to unlock the kettle lid to realize the upward movement of the filter cartridge while opening the kettle lid, so that the user can take and place the filter cartridge from the side of the filter cartridge to avoid being scalded by the rising steam.

[0050] The present invention is further described in detail below with reference to the accompanying drawings.

[0051] like Figures 1 to 9 FIG. 1 is a preferred embodiment of the kettle of the present invention, which comprises a kettle body 1 , a kettle cover 2 , a filter assembly 3 , a movable frame 4 , a first elastic member 5 , a second elastic member 6 and a locking assembly 7 .

[0052] The kettle body 1 is hollow inside and has an opening 11 at the top. A fixing frame 12 is installed near the opening inside the kettle body 1. The front edge of the kettle body 1 located at the opening 11 is bent inwards to form a stopper 13. The left and right edges of the kettle body 1 located at the opening 11 are bent inwards to form a support 14. The top surface height of the support 14 is lower than the top surface height of the stopper 13. Specifically, the front side of the fixing frame 12 has two mounting seats 121 arranged side by side. The mounting seats 121 are provided with a receiving groove 1211 with an opening facing upward. The inner side wall of the mounting seat 121 is provided with a limiting groove 1212 that intersects with the receiving groove 1211. The limiting groove 1212 is in a strip shape and extends in the vertical direction. The top of the fixing frame 12 has a hinge seat 122.

[0053] The pot cover 2 is hinged on the pot body 1, and can open or close the opening 11 of the pot body 1. Specifically, the interior of the pot cover 2 is hollow, and a rotating shaft 21 is installed at the rear end of the pot cover 2, and both ends of the rotating shaft 21 are rotatably connected to the hinge seat 122.

[0054] The filter assembly 3 can enter and exit the interior of the kettle body 1 from the opening 11, and includes a filter cartridge 32 and a bracket 31 for supporting the top of the filter cartridge 32. Specifically, a step hole 310 is provided on the bracket 31 in the height direction for inserting the filter cartridge 32, and the top edge of the filter cartridge 32 is bent outward to form a convex edge 321, which is limited to the step surface of the step hole 310, so as to facilitate the removal of the filter cartridge 32 from the bracket 31; the side of the rear end of the bracket 31 is provided with two side-by-side mounting columns 311, and the left and right side edges of the bracket 31 are provided with outwardly extending supporting edges 312 for easy handholding.

[0055] There are two movable frames 4, which correspond to the above-mentioned mounting seats 121 one by one. Each movable frame 4 is accommodated in the accommodating groove 1211 of the corresponding mounting seat 121 and can move up and down in the accommodating groove 1211. Specifically, the movable frame 4 is provided with a mounting groove 41 with a top opening corresponding to the above-mentioned mounting column 311, which is used for the corresponding mounting column 311 to be inserted, so as to facilitate the loading and unloading of the bracket 31 on the movable frame 4; a limiting protrusion 42 is convexly provided on the outer wall of the movable frame 4, and at least a part of the limiting protrusion 42 can be inserted in the limiting groove 1212 of the above-mentioned mounting seat 121 so as to slide up and down, thereby limiting the extreme moving position of the movable frame 4, especially the highest position, to prevent the movable frame 4 from being separated from the fixed frame 12.

[0056] The first elastic member 5 is a compression spring installed in the receiving groove 1211 of the mounting seat 121. The two ends of the first elastic member 5 respectively abut against the bottom wall inside the receiving groove 1211 and the bottom wall of the movable frame 4, so that the movable frame 4 always has a tendency to rise away from the fixed frame 12.

[0057] The second elastic member 6 is a torsion spring, which is sleeved on the rotating shaft 21. The two ends of the second elastic member 6 are respectively abutted against the fixing frame 12 and the pot cover 2, so that the pot cover 2 always has the tendency to open the opening 11 and flip upward.

[0058] The locking assembly 7 is installed on the pot cover 2, and is used to lock and unlock the relative position of the pot cover 2 and the pot body 1, and includes a locking seat 71, a third elastic member 72, a button 73 and a fourth elastic member 74. Specifically, the locking seat 71 can be movably accommodated inside the pot cover 2 forward and backward, and the front end of the locking seat 71 has a locking tongue 711 corresponding to the stopper 13, and the end of the locking tongue 711 has a guiding inclined surface 7111 that gradually decreases from front to back, and the top of the locking seat 71 has a first inclined surface 712 that gradually increases from front to back; the third elastic member 72 is a compression spring, which is arranged inside the pot cover 2, and the two ends of the third elastic member 72 are respectively abutted between the inner wall of the pot cover 2 and the outer wall of the locking seat 71, so that the locking seat 71 always has a tendency to move forward, so that the locking tongue 711 always has a tendency to move toward the stopper 13; the button 73 can be movably arranged inside the pot cover 2 up and down, and the top of the button 73 The button 73 is exposed on the top surface of the pot cover 2, and the bottom end of the button 73 has a second inclined surface 731 that abuts against the first inclined surface 712. The slope of the second inclined surface 731 is consistent with that of the first inclined surface 712. In this way, the up and down movement of the second inclined surface 731 can stably drive the first inclined surface 712 to move forward and backward. A limit block 732 is provided on the outer side wall of the lower part of the button 73. When the button 73 rises to a high position, the limit block 732 abuts against the bottom of the top wall inside the pot cover 2, thereby preventing the button 73 from detaching from the pot cover 2; the fourth elastic member 74 is a compression spring, which is arranged inside the pot cover 2. The two ends of the fourth elastic member 74 respectively abut between the bottom wall inside the pot cover 2 and the bottom wall of the button 73, so that the button 73 always has an upward trend.

[0059] In the locked state, Figures 3 to 6 As shown, the locking tongue 711 abuts against the lower part of the stopper 13, the pot cover 2 overcomes the effect of the second elastic member 6 to close the opening 11, and abuts against the upper part of the bracket 31 of the filter assembly 3, so that the movable frame 4 overcomes the effect of the first elastic member 5 and moves downward to the fixed frame 12, and the supporting edge 312 of the bracket 31 abuts against the support portion 14;

[0060] In the unlocked state, Figure 8 and Fig. 9 As shown, the locking tongue 711 is disengaged from the stopper 13, and the lid 2 opens the opening 11 under the action of the second elastic member 6, and releases the abutment against the bracket 31, so that the movable frame 4 is away from the fixed frame 12 under the action of the first elastic member 5, and drives the filter assembly 3 to rise and extend out of the opening 11, and there is a gap between the support edge 312 of the bracket 31 and the support portion 14 for a finger to be inserted from the side.

[0061] The working principle of this embodiment is as follows:

[0062] (1) Figures 3 to 6 As shown, the pot cover 2 is in a locked state, the locking tongue 711 abuts against the lower part of the stopper 13, the pot cover 2 overcomes the effect of the second elastic member 6 to close the opening 11, and abuts against the upper part of the bracket 31 of the filter assembly 3, so that the movable frame 4 overcomes the effect of the first elastic member 5 and moves down to approach the fixed frame 12;

[0063] (2) When the boiling object inside the filter assembly 3 needs to be replaced:

[0064] ① The user only needs to press the button 73 downwards to make the second inclined surface 731 squeeze the first inclined surface 712, driving the locking seat 71 to move backwards, so that the locking tongue 711 is separated from the stopper 13. Figure 8 and Fig. 9 As shown, in the unlocked state, the pot cover 2 will flip upwards under the action of the second elastic member 6 to open the opening 11 and release the contact with the bracket 31, which is equivalent to releasing the limit of the bracket 31 on the movable frame 4. Therefore, the movable frame 4 will drive the filter assembly 3 to rise and extend out of the opening 11 under the action of the first elastic member 5. The user can lift the filter assembly 3 upward from the side of the bracket 31 through the supporting edge 312 and completely remove it from the opening 11 to avoid being scalded by the rising steam;

[0065] ② After replacing the boiled object inside the filter assembly 3, the user can align the mounting column 311 of the bracket 31 with the mounting groove 41 of the movable frame 4, put the filter assembly 3 into the kettle body 1 through the opening 11, and then flip the kettle cover 2 downward. After the guiding inclined surface 7111 of the locking tongue 711 contacts the stopper 13, it will overcome the effect of the third elastic member 72 under the action of the stopper 13 and retract inward until the locking tongue 711 moves to the bottom of the stopper 13. The locking tongue 711 will extend outward under the action of the third elastic member 72 and abut against the bottom of the stopper 13. At the same time, in the process of flipping the kettle cover 2 downward, after the bottom surface of the kettle cover 2 contacts the top of the bracket 31, it will drive the bracket 31 to move downward, so that the movable frame 4 overcomes the effect of the first elastic member 5 and moves down close to the fixed frame 12. Figures 3 to 6 As shown, at this time, the filter assembly 3 is completely accommodated inside the kettle body 1.
