As shown in fig. 1 and 2, in one embodiment, a water kettle 10 is disclosed comprising: a kettle body 100, the kettle body 100 being provided with a first sealing structure 110 and a water storage cavity (not shown) having an opening 120; a kettle cover 200, wherein the kettle cover 200 is provided with a second sealing structure 210 for sealing fit with the first sealing structure 110; the first limiting piece 310 is arranged at an interval relative to the first sealing structure 110; when the lid 200 covers the opening 120, the first limiting member 310 abuts against the second sealing structure 210, so that the second sealing structure 210 abuts against the first sealing structure 110 and is in sealing fit with the first sealing structure 110.

When the kettle 10 of the above embodiment is used, when the kettle lid 200 is covered on the opening 120 of the water storage cavity on the kettle body 100, the first limiting member 310 abuts against the second sealing structure 210, so that an abutting force towards the first sealing structure 110 is applied to the second sealing structure 210 of the kettle lid 200, the second sealing structure 210 abuts against the first sealing structure 110 on the kettle body 100, so that the first sealing structure 110 and the second sealing structure 210 realize tight sealing fit, water in the water storage cavity can be prevented from overflowing from the edge of the kettle lid 200 due to the inclination of the kettle body 100, and the water in the water storage cavity can be prevented from pushing up the kettle lid 200 due to boiling, so that the water overflows from the edge of the kettle lid 200, a heating platform can be protected, and potential safety hazards can be avoided. When the lid 200 is required to be removed to open the opening 120 of the water storage chamber, only an external force in a direction opposite to the abutment force needs to be applied to the lid 200, so that the second sealing structure 210 is separated from the first sealing structure 110 against the abutment force.

It should be noted that, the cover 200 is covered on the opening 120 of the water storage cavity, and can be realized by the clamping fit between the cover 200 and the kettle body 100, and only the requirement that the cover 200 can seal the opening 120 of the water storage cavity is satisfied. The sealing cooperation between the first sealing structure 110 and the second sealing structure 210 can be realized by cooperation between sealing rings or cooperation between sealing gaskets, and only the requirement that the kettle cover 200 seals the opening 120 of the water storage cavity is met. The first limiting member 310 may be made of an elastic restoring material, so that the lid 200 is conveniently closed and opened (as shown in D direction of fig. 1), and after the lid 200 is closed, an elastic restoring force of the first limiting member 310 acts on the second sealing structure 210, so that the first sealing structure 110 and the second sealing structure 210 achieve tight sealing fit. The kettle 10 may be an electric kettle, a hot water kettle or other container requiring water.

As shown in fig. 2 and 3, in one embodiment, the pot lid 200 includes an inner lid 220 and an outer lid 230, the second sealing structure 210 is disposed between the inner lid 220 and the outer lid 230, and the outer lid 230 is provided with a second limiting member 400; when the inner cap 220 and the outer cap 230 both cover the opening 120, the first limiting member 310 abuts against one end of the second limiting member 400, and the other end of the second limiting member 400 abuts against the second sealing structure 210, so that the second sealing structure 210 abuts against the first sealing structure 110 and is in sealing fit with the first sealing structure 110. In this way, when the inner cap 220 and the outer cap 230 are both covered on the opening 120 of the water storage cavity, the first limiting member 310 applies an abutting force on the second limiting member 400, so that the abutting force is transferred to the second sealing structure 210, and meanwhile, the acting force between the inner cap 220 and the outer cap 230 and the acting force between the outer cap 230 and the kettle body 100 can also be transferred to the second sealing structure 210 through the second limiting member 400, so that the second sealing structure 210 can receive a larger force towards the first sealing structure 110, the second sealing structure 210 and the first sealing structure 110 are combined more tightly, the sealing reliability is further ensured, and the water in the water storage cavity is prevented from overflowing from the edge of the kettle cap 200.

As shown in fig. 2, 3 and 6, in one embodiment, one end of the second limiting member 400 is provided with a first guiding surface 410, the other end of the second limiting member 400 is provided with a second guiding surface 420, the first limiting member 310 is provided with a third guiding surface 311 close to the first sealing structure 110 and a fourth guiding surface 312 far from the first sealing structure 110, and the third guiding surface 311 can be in guiding fit with the first guiding surface 410, and the fourth guiding surface 312 can be in guiding fit with the second guiding surface 420. In this way, when the lid 200 is covered on the opening 120, the second limiting member 400 moves towards the position close to the first limiting member 310, and the second limiting member 400 can smoothly overcome the friction force with the first limiting member 310 by guiding and matching the second guiding surface 420 with the fourth guiding surface 312. When the opening 120 of the water storage cavity needs to be opened, only a force needs to be applied to the pot cover 200, and under the guiding cooperation of the first guiding surface 410 and the third guiding surface 311, the friction force between the second limiting piece 400 and the first limiting piece 310 can be smoothly overcome, so that the second limiting piece 400 and the first limiting piece 310 can be separated more labor-saving, and the opening 120 of the water storage cavity is opened. The first guide surface 410, the second guide surface 420, the third guide surface 311 and the fourth guide surface 312 may be inclined with respect to the horizontal plane, so that the guiding and matching effects are good.

As shown in fig. 2, 3 and 6, in one embodiment, the kettle 10 further includes a mounting seat 320 and an elastic member 330, the inner wall of the water storage cavity is provided with a mounting groove 130, the mounting seat 320 and the elastic member 330 are both disposed in the mounting groove 130, one side of the mounting seat 320 is provided with a first limiting member 310, the first limiting member 310 extends out of the mounting groove 130 into the water storage cavity, the other side of the mounting seat 320 is connected with one end of the elastic member 330, and the other end of the elastic member 330 is abutted against the bottom wall of the mounting groove 130 and is used for enabling the mounting seat 320 to drive the first limiting member 310 to reciprocate along the length direction of the elastic member 330. Thus, when the pot lid 200 needs to be covered on the opening 120 of the water storage cavity, the second sealing structure 210 or the second limiting piece 400 just contacts with the first limiting piece 310, the mounting seat 320 overcomes the elastic force of the elastic piece 330 under the action of friction force to drive the first limiting piece 310 to move towards the mounting groove 130, so that the contact area between the second sealing structure 210 or the second limiting piece 400 and the first limiting piece 310 is reduced, and the resistance to the second sealing structure 210 or the second limiting piece 400 is reduced, so that the pot lid 200 can be covered on the opening 120 of the water storage cavity more laborsaving. After the lid 200 is covered on the opening 120 of the water storage cavity, under the elastic force of the elastic element 330, the mounting seat 320 resets, so that the first limiting element 310 resets, and the first limiting element 310 can provide a sufficient abutting force to the second sealing structure 210 or the second limiting element 400, so as to ensure that the second sealing structure 210 can achieve a tight sealing fit with the first sealing structure 110. When the opening 120 of the water storage cavity needs to be opened, an external force in the opposite direction to the abutting force is applied to the kettle cover 200, and the friction force between the second sealing structure 210 or the second limiting piece 400 and the first limiting piece 310 can make the mounting seat 320 overcome the elastic force of the elastic piece 330 to drive the first limiting piece 310 to move towards the mounting groove 130, so that the contact area between the second sealing structure 210 or the second limiting piece 400 and the first limiting piece 310 is reduced, and the resistance borne by the second sealing structure 210 or the second limiting piece 400 is reduced, so that the opening 120 of the water storage cavity can be opened more laborsaving. The elastic member 330 may be a spring, a reed, or other elements having an elastic restoring function.

As shown in fig. 1, further, the kettle 10 further includes a hand-held portion 500, the hand-held portion 500 has a first end, the first end has a mounting groove 130, the first end is connected with the outer wall of the kettle body 100, and the first end is disposed above the first sealing structure 110. In this way, the electric kettle 10 is convenient to hold, and meanwhile, the mounting groove 130 is formed on the handheld part 500, so that the structural strength of the kettle body 100 is improved. The hand-held part 500 may be a handle or a grip, and is required to be held conveniently.

As shown in fig. 5, in the above-described embodiment, the first sealing structure 110 includes a first sealing section 111, a second sealing section 112, and a connecting section 113 for connecting the first sealing section 111 and the second sealing section 112, where the first sealing section 111 is disposed close to the second sealing structure 210, and the first sealing section 111 is disposed opposite to the second sealing section 112. In this way, the contact area between the first sealing structure 110 and the second sealing structure 210 is increased, so that the first sealing structure 110 and the second sealing structure 210 realize surface sealing, and the sealing reliability is enhanced. The connecting section 113 may be configured as an arc transition structure, and a space may be left between the first sealing section 111 and the second sealing section 112, so that when the first sealing section 111 receives pressure from the second sealing structure 210, the first sealing section 111 may be tightly attached to the second sealing section 112 and deform, thereby further enhancing the sealing reliability.

As shown in fig. 2, the second sealing structure 210 includes an elastic bending section 211 according to any of the above embodiments, and the elastic bending section 211 is disposed near the first sealing structure 110. In this way, when the second sealing structure 210 is abutted against the first sealing structure 110 by an abutment force, the elastic bending section 211 can bend and deform, so that the contact area between the first sealing structure 110 and the second sealing structure 210 is increased, the first sealing structure 110 and the second sealing structure 210 realize surface sealing, and the sealing reliability is enhanced. The first sealing section 111 may be horizontally disposed, so that the elastic bending section 211 is tightly adhered to the upper surface of the first sealing section 111 after bending and deforming, thereby realizing tight surface sealing.

As shown in fig. 4, in any of the above embodiments, the first sealing structure 110 is disposed on the inner wall of the water storage cavity, and the first sealing structure 110 is disposed near the opening 120. In this way, the first sealing structure 110 may be disposed closer to the second sealing structure 210, so that the first sealing structure 110 can be in contact with the second sealing structure 210 more tightly, and the sealing reliability is ensured.

As shown in fig. 7, the outer wall of the inner cap 220 is optionally provided with a first stopper 221 for limiting the axial displacement of the inner cap 220. In this way, the first stopper 221 can restrict the movement of the inner lid 220 in the axial direction of the jug body 100, and can restrict the movement of the lid in the axial direction of the jug body 100. The first limiting structure 221 may be realized by a clamping or pin hole, so long as the inner cover 220 is prevented from moving along the axial direction of the kettle body 100.

As shown in fig. 7, in one embodiment, the first limiting structure 221 includes a first limiting body 2211 and a second limiting body 2212 disposed at an included angle, and the first limiting body 2211 and the second limiting body 2212 cooperate to form a limiting groove 2213, one end of the first sealing structure 110 and one end of the second sealing structure 210 are both clamped in the limiting groove 2213, and one end of the first sealing structure 110 and one end of the second sealing structure 210 are mutually abutted. In this way, the one end of the first sealing structure 110 and the one end of the second sealing structure 210 are both clamped in the limiting groove 2213, and the one end of the first sealing structure 110 and the one end of the second sealing structure 210 are mutually abutted, so that the inner cover 220 receives the abutting force from the one end of the first sealing structure 110 and the one end of the second sealing structure 210, thereby being capable of limiting the inner cover 220 to move along the axial direction of the kettle body 100, and simultaneously ensuring the sealing reliability between the first sealing structure 110 and the second sealing structure 210. The limiting groove 2213 may be U-shaped or V-shaped. Preferably V-shaped, to enable an end of the first seal structure 110 to mate more tightly with an end of the second seal structure 210. Meanwhile, the kettle cover 200 can rotate relative to the kettle body 100 by taking the abutting part of one end of the first sealing structure 110 and one end of the second sealing structure 210 as a fulcrum, so that the opening flexibility of the kettle cover 200 is improved.

As shown in fig. 1, the first limiting structure 221 may be disposed close to the spout 600, and the first limiting member may be disposed at an interval relative to the spout 600, for example, the first limiting member may be disposed close to the handle, so that the first limiting structure and the first limiting member 310 are disposed relatively, and the stability of the sealing fit between the lid 200 and the kettle body 100 may be further improved.

In one embodiment, the first sealing structure 110 includes a first sealing section 111, a second sealing section 112, and a connecting section 113 for connecting the first sealing section 111 and the second sealing section 112, the first sealing section 111 is disposed adjacent to the second sealing structure 210, and the first sealing section 111 is disposed opposite to the second sealing section 112; the second sealing structure 210 includes an elastic bending section 211, the elastic bending section 211 is disposed near the first sealing structure 110, and the first sealing section 111, the second sealing section 112, the connecting section 113 and the elastic bending section 211 are all clamped in the limiting groove 2213, and the elastic bending section 211 is abutted to the first sealing section 111. So, after the elastic bending section 211 is elastically deformed, the elastic bending section can be matched with the first sealing section 111, and can be matched with the first limiting body 2211, and the second sealing section 112 can be matched with the second limiting body 2212, so that the sealing reliability is improved, and the inner cover 220 is not easy to move along the axis direction of the kettle body 100.

As shown in fig. 8, a second limiting structure 222 for limiting radial displacement of the inner cap 220 is optionally provided on the outer wall of the inner cap 220. In this way, the second limiting structure 222 can limit the movement of the inner cap 220 along the radial direction of the opening 120, so that the movement of the cap body along the radial direction of the opening 120 can be limited. The second limiting structure 222 may be realized by a clamping or pin hole, which only needs to prevent the inner cover 220 from moving along the radial direction of the opening 120.

As shown in fig. 8, in one embodiment, the second limiting structure 222 includes a third limiting body 2221, a fourth limiting body 2223 and a limiting projection 2222 that are connected to each other, the third limiting body 2221, the fourth limiting body 2223 and the limiting projection 2222 can be in abutting fit with the first sealing structure 110, the limiting projection 2222 is disposed between the third limiting body 2221 and the fourth limiting body 2223, the third limiting body 2221 is disposed near the outer cover 230, and the third limiting body 2221 and the fourth limiting body 2223 are disposed obliquely with respect to the limiting projection 2222. In this way, when the lid 200 needs to be covered on the opening 120 of the water storage cavity, the inclined fourth limiting body 2223 abuts against the first sealing structure 110 first, and the first sealing structure 110 continues to cross the fourth limiting body 2223 and the limiting projection 2222 under the action of the pressing force and then abuts against the third limiting body 2221, so that the inner lid 220 can be prevented from moving along the radial direction of the opening 120 under the action of the abutting force. Meanwhile, the inclined third and fourth limiting bodies 2221 and 2223 also facilitate the inner lid 220 to be tightly covered or separated from the jug body 100. The first sealing structure 110 may be made of an elastic material, so that when the first sealing structure 110 abuts against the third limiting body 2221, the first sealing structure 110 also applies an elastic component force towards the water storage cavity to the inner cover 220, so that the inner cover 220 can be further prevented from moving along the radial direction of the opening 120.

The number of the second limiting structures 222 may be one or at least two, and when the number of the second limiting structures 222 is at least two, the second limiting structures 222 may be uniformly arranged along the circumferential direction of the inner cap 220, so that the inner cap 220 is stressed uniformly, and the radial movement of the inner cap 220 can be stably limited.

In one embodiment, a water purifying apparatus is also disclosed, comprising the water kettle 10 of any of the embodiments described above; and a water purifying device provided with a heating platform for heating the water kettle 10.

When the water purifying and drinking device of the above embodiment is used, when the kettle lid 200 is covered on the opening 120 of the water storage cavity on the kettle body 100, the first limiting member 310 abuts against the second sealing structure 210, so that an abutting force towards the first sealing structure 110 is applied to the second sealing structure 210 of the kettle lid 200, the second sealing structure 210 abuts against the first sealing structure 110 on the kettle body 100, the first sealing structure 110 and the second sealing structure 210 achieve tight sealing fit, water in the water storage cavity can be prevented from overflowing from the edge of the kettle lid 200 due to inclination of the kettle body 100, and when the kettle 10 is placed on the heating platform of the water purifying and drinking device for heating, the water in the water storage cavity can be prevented from pushing up the kettle lid 200 due to boiling, so that the edge of the kettle lid 200 overflows, and the heating platform can be protected, and potential safety hazards can be avoided. When the lid 200 is required to be removed to open the opening 120 of the water storage chamber, only an external force in a direction opposite to the abutment force needs to be applied to the lid 200, so that the second sealing structure 210 is separated from the first sealing structure 110 against the abutment force.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
