[0032] The present application will be further described in conjunction with the drawings and specific embodiments.
[0033] Embodiment one
[0034] Referring to Figures 1 to 9 The present application provides a pouring anti-overflow kettle, which comprises a kettle body 1, a spout 2 arranged on the front side of the kettle body 1, a handle 3 arranged on the rear side of the kettle body 1, and a kettle cover 10 covering the upper opening 4 of the kettle body 1. The spout 2 is provided with a switch valve 5. The switch valve 5 adopts an existing valve body capable of closing or opening the channel, and its arrangement position is not limited, such as being arranged at the inlet of the spout 2, the outlet of the spout 2 or inside the spout 2, etc., as long as it can control the opening and closing of the spout 2.
[0035] The kettle cover 10 is provided with a steam inlet 101, a steam outlet 103, and a steam channel 102 formed inside the kettle cover 10 and communicating with the steam inlet 101 and the steam outlet 103. In the covering state of the kettle cover 10, the steam generated by the hot water in the kettle body 1 enters from the steam inlet 101, passes through the steam channel 102 and is sprayed from the steam outlet 103, realizing normal output of the steam.
[0036] Specifically, for the convenience of description, the center point o of the kettle cover 10 and the line extending in the front-rear direction are defined as the center line I, and the steam channel 102 has at least one blocking section 104 extending along the left-right direction through the center line I. As in the present embodiment, the number of blocking sections 104 is three, and the three blocking sections 104 are connected end to end to form a detour channel arranged back and forth in the left-right direction.
[0037] The kettle is supported by the spout 2 and the handle 3 in the front and back directions, respectively, and is generally only tilted to the left or right when the kettle is tilted; the spout 2 is provided with a switch valve 5, which can be closed in advance by the switch valve 5; and in the anti-overflow design of the kettle cover 10, the steam passage 102 is designed to have at least one blocking section 104 that is centered on the line I and extends in the left-right direction. When the kettle is tilted to the left, the left end (A position) of the blocking section 104 is at a low position and the right end (B position) is at a high position, so that the water in the kettle body 1 is difficult to reach the right end (B position) of the blocking section, thereby achieving anti-overflow; when the kettle is tilted to the right, the right end (B position) of the blocking section 104 is at a low position and the left end (A position) is at a high position, so that the water in the kettle body 1 is difficult to reach the left end (A position) of the blocking section, thereby achieving anti-overflow. The simple structure design of the steam passage 102 achieves the effect of anti-overflow, without the need to set up anti-overflow valves and other structures, effectively reducing the cost, and being more reliable. There are no complex parts, reducing assembly difficulty and cost, facilitating mass production, and effectively improving production capacity.
[0038] Specifically, three blocking sections 104 are used to form a detour passage, forming a multi-channel anti-overflow structure, which has better anti-overflow effect. At the same time, the two ends of the middle blocking section 104 are located at the left and right sides of the kettle cover 10 (i.e. the A position and the B position), increasing the maximum distance in the left-right direction and better improving the anti-overflow effect; the front and rear blocking sections 104 are connected to the steam outlet 103 and the steam inlet 101, respectively. Of course, in other embodiments, the number of blocking sections 104 can also be set according to actual conditions, such as one, two or more than two.
[0039] Specifically, in this embodiment, the upper opening 4 of the kettle body 1 is fixed with a fixed seat 6, and the fixed seat 6 is provided with a window 7; the kettle cover 10 includes a flip cover 12, which is hinged to the fixed seat 6 and closes or opens the window 7 of the fixed seat 6; the steam inlet 101, the steam outlet 103 and the steam passage 102 are arranged on the flip cover 12.
[0040] Further, the flip cover 12 is also provided with a buckle assembly 14 and a flip cover handle 13, the flip cover handle 13 is rotatably arranged and drivingly connected to the buckle assembly 14, so as to drive the buckle assembly 14 to extend out of the flip cover 12 or retract into the flip cover 12, and when the flip cover 12 is closed on the window 7, the buckle assembly 14 extends out of the outer side of the flip cover 12 and is buckled on the fixed seat 6 of the kettle body 1, achieving the closing fixation of the flip cover 12. The flip cover 12 is locked and unlocked by rotating the flip cover handle 13, which is more convenient to operate, and after the flip cover 12 is unlocked, it can also be opened or closed by holding the flip cover handle 13, avoiding direct contact with the flip cover body and causing burns; this embodiment is specifically realized by the torsional spring 172 arranged in the following.
[0041] Specifically, the buckle assembly 14 comprises a buckle 141 slidably assembled in the cover 12 and a buckle spring 142 applying elastic force to the buckle 141 to make it extend out of the cover 12; as in the embodiment, the buckle 141 has two guide arms 144 at the rear end and a clamping arm 145 at the front end, the two guide arms 144 are arranged in a guide manner with the cover 12, the front side of the cover 12 is provided with a lateral opening 1211, and the clamping arm 145 is arranged in the lateral opening 1211. The cover 12 is further provided with a rotating shaft 15, the cover handle 13 is assembled on the rotating shaft 15, and the rotating shaft 15 has a first branch arm 151 connected with the buckle 14, specifically, the first branch arm 151 is hinged to one of the guide arms 144 of the buckle 141. In the state that the cover 12 is closed to the accommodation window 7, the buckle 141 is continuously kept in the state of being buckled with the fixing seat 6 of the kettle body 1 under the elastic force applied by the buckle spring 142. When the cover handle 13 is counterclockwise rotated, the buckle 141 is driven to retract backward by the first branch arm 151 to realize unlocking, at this time, the retraction of the buckle 141 needs to overcome the elastic force of the buckle spring 142. When the cover handle 13 is released, the buckle 141 is driven to push forward by the elastic force of the buckle spring 142 and is buckled on the fixing seat 6 of the kettle body 1 again. Or when the buckle spring 142 cannot drive the buckle 141 to push forward alone, the cover handle 13 can also be clockwise rotated by applying external force, and the buckle 141 is driven to push forward under the double actions of the external force and the buckle spring 142.
[0042] Specifically, the clamping arm 145 of the buckle 141 is sleeved with a buckle rubber ring 143, when the clamping arm 145 of the buckle 141 is in the extended position, the buckle rubber ring 143 is sealingly matched with the lateral opening 1211 to fill the gap between the clamping arm 145 of the buckle 141 and the lateral opening 1211.
[0043] Further, in order to intuitively feel whether the buckle 141 is buckled in place, the structure of the elastic top rod 16 is designed in the embodiment; the specific structure is as follows: the flip handle 13 is further provided with a second arm 134, and the flip 12 is further provided with an elastic top rod 16; specifically, the elastic top rod 16 is composed of a top rod 161 and a top rod spring 162, and the top rod spring 162 exerts an upward elastic force on the top rod 161. The elastic top rod 16 is located on the movement track of the second arm 134; when the flip handle 13 drives the buckle assembly 14 to extend out of the flip 12, the second arm 134 presses the elastic top rod 16 from the first side of the elastic top rod 16 and reaches the second side of the elastic top rod 16; when the flip handle 13 drives the buckle assembly 14 to retract into the flip 12, the second arm 134 presses the elastic top rod 16 from the second side of the elastic top rod 16 and reaches the first side of the elastic top rod 16. When the second arm 134 passes the elastic top rod 16 each time, the elastic top rod 16 will be squeezed first, and then reset, and after resetting, it will be pressed against the inner wall of the flip 12 to make a sound, so that whether the switching is in place can be directly judged by the sound.
[0044] Further, the flip handle 13 includes a handle upper cover 131, a handle middle cover 132 and a handle lower cover 133, the handle lower cover 133 is assembled at the bottom of the handle middle cover 132 and is provided with the second arm 134, that is, the handle lower cover 133 and the second arm 134 are integrally connected; the handle upper cover 131 is fixed at the top of the handle middle cover 132, and the handle lower cover 133 is also fixedly connected with the rotating shaft 15 to form a rotatable structure. Of course, in other embodiments, the structure of the flip handle 13 is not limited to this, for example, the handle upper cover 131 and the handle middle cover 132 can also be an integrally formed structure, and for example, the handle lower cover 133 and the second arm 134 can also be an assembled structure.
[0045] Specifically, the cover 12 includes an upper cover 124, an inner cover 123, a middle cover 122 and a lower cover 121. The lower cover 121 is fixed to the lower side of the middle cover 122 and accommodated in the accommodating window 7 of the fixing seat 6. The middle cover 122 is hingedly arranged with the fixing seat 6 through a connecting shaft 171. The inner cover 123 is fixed to the upper side of the middle cover 122 and together forms the steam passage 102 and the steam outlet 103. The steam inlet 101 is formed on the lower cover 121 and connected with the steam passage 102. In this way, the steam inlet 101 can communicate with the inner cavity of the kettle body 1. The upper cover 124 covers the inner cover 123 and is fixedly connected with the middle cover 122. The buckle assembly 14 is arranged on the lower cover 121. Corresponding through holes are formed in the upper cover 124, the inner cover 123 and the middle cover 122 (i.e. the through hole 1241 of the upper cover 124, the through hole 1231 of the inner cover 123 and the through hole 1221 of the middle cover 122). The cover handle 13 is installed on the lower cover 121 by sequentially penetrating the through hole 1241 of the upper cover 124, the through hole 1231 of the inner cover 123 and the through hole 1221 of the middle cover 122. The elastic top rod 16 is installed on the middle cover 122 and penetrates the inner cover 123. The second branch arm 134 is located between the upper cover 124 and the inner cover 123. In this way, the connection of the cover 12 is realized.
[0046] The inner cover 123 and the middle cover 122 are further provided with an inner cover silica gel 125. The gap between the inner cover 123 and the middle cover 122 is filled with the inner cover silica gel 125, so that the steam passage 102 is sealed.
[0047] The middle cover 122 and the lower cover 121 are provided with a steam port silica gel 18 to fill the gap at the connection between the steam inlet 101 and the steam passage 102.
[0048] The lower cover 121 is provided with a silica gel ring 19. When the cover 12 is closed on the accommodating window 7, the silica gel ring 19 forms a sealed fit with the fixing seat 6 to fill the gap between the lower cover 121 and the fixing seat 6. The sealed fit of each connection position is realized to ensure the sealing. Of course, in other embodiments, other sealing structures can be used to realize the sealed fit of the above connections.
[0049] Further, the fixing seat 6 and the cover 12 are provided with a torsion spring 172. The torsion spring 172 applies a torsion force to the cover 12 away from the fixing seat 6. Specifically, the torsion spring 172 is sleeved on the connecting shaft 171 connecting the fixing seat 6 and the cover 12. Two torsion arms of the torsion spring 172 abut against the fixing seat 6 and the middle cover 122 of the cover 12, respectively. In this way, when the cover 12 and the kettle body 1 are unlocked, the cover 12 is automatically flipped up under the action of the torsion spring 172. The hand operation of the cover 12 is avoided to be scalded by the steam.
