Description

Technical Field

[0001] The utility model relates to the technical field of water boiling bottles, in particular to a water boiling bottle with smooth water discharge. Background Art

[0002] This section only provides background information related to the present application to help those skilled in the art understand the present application more thoroughly and accurately, and it is not necessarily prior art.

[0003] The existing centrifugal pump is a pump that transports liquid by the centrifugal force generated by the rotation of the impeller. When the impeller in the centrifugal pump is driven by the motor to rotate, the fluid filled between the blades will rotate with the impeller. Under the action of centrifugal force, the fluid will be thrown out from the grooves between the blades and discharged from the water outlet on the pump shell. The outflow of the fluid will cause a vacuum to form in the impeller inlet space, and the external fluid will be automatically sucked into the impeller for replenishment under the action of atmospheric pressure. Since the centrifugal pump works continuously, the fluid is sucked in and discharged, forming a continuous flow of the fluid, thereby continuously transporting the fluid.

[0004] When a centrifugal pump is applied to a water bottle, the centrifugal pump is usually arranged horizontally, and the pump housing is provided with a water inlet arranged perpendicular to its axis and the water inlet is connected to the inner tank of the water bottle to discharge water. When the centrifugal pump is started, the boiled water in the inner tank enters the pump chamber of the pump housing through the water inlet and rotates with the impeller. Under high-speed rotation, the boiled water begins to boil and produces water vapor. The density of the water vapor decreases and is less affected by the centrifugal force. It cannot be discharged from the water outlet on the pump housing with the water flow, and is accumulated at the top of the pump chamber to form an air binding phenomenon. Negative pressure is formed at the top of the impeller, and the water flow cannot be sucked in and replenished, which causes a vacuum phenomenon and causes unsmooth water discharge.

[0031] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the modules or components referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0034] See also Figure 1-6The utility model provides a water bottle with smooth water discharge, comprising an inner liner 1, a water inlet pipe 2, a centrifugal pump 3 and a water outlet pipe 4. A water outlet hole 11 is provided at the bottom of the inner liner 1; the water inlet pipe 2 is arranged at the water outlet hole 11 and is connected thereto; the centrifugal pump 3 comprises a pump casing, an impeller 32 arranged in the pump casing and a driving motor 34 connected to the impeller 32 in a transmission manner; a pump chamber 311 is provided inside the pump casing, and the impeller 32 is rotatably arranged in the pump chamber 311; the pump The shell is also provided with a water inlet 312, and a water inlet channel 3121 connected to the pump chamber 311 is formed inside the water inlet 312; the other end of the water inlet pipe 2 is connected to the water inlet 312 and conducted; in addition, a water outlet 313 is also provided on the pump shell, and the water outlet 313 is arranged in the tangential direction of the impeller 32; a water outlet channel 3131 connected to the pump chamber 311 is formed inside the water outlet 313; one end of the water outlet pipe 4 is connected to the water outlet 313 and conducted.

[0035] Therefore, during the normal operation of the centrifugal pump 3, by driving the impeller 32 to rotate, the impeller 32 rotates to form a negative pressure in the pump chamber 311, and the water in the inner tank 1 can enter the pump chamber 311 through the water outlet 11, the water inlet pipe 2 and the water inlet 312 in turn, and under the centrifugal force of the impeller 32, the water in the pump chamber 311 is discharged from the water outlet 313 to the water outlet pipe 4, and finally flows out through the water outlet pipe 4 for the user to drink.

[0036] Among them, since the inner liner 1 of the water bottle contains boiling water, when the boiling water rotates with the impeller 32, under high-speed rotation, the boiling water begins to boil and produce water vapor, the density of the water vapor becomes smaller, and the influence of centrifugal force is low. It is easy to accumulate inside the pump chamber 311 and cannot be discharged from the water outlet channel 3131 with the water flow, thereby forming an air binding phenomenon. Therefore, in order to solve the above phenomenon, the present application arranges the water inlet 312, the pump housing and the impeller 32 coaxially so that the water inlet channel 3121 and the pump chamber 311 are interconnected in the axial direction. In this way, the water vapor accumulated inside the pump chamber 311 can be directly discharged into the water inlet channel 3121, thereby avoiding the occurrence of air binding phenomenon, and then ensuring smooth water discharge.

[0037] See also Figure 3-6 Specifically, the pump housing includes an upper housing 31 and a lower housing 33 connected to each other from top to bottom. The upper housing 31 has the pump chamber 311 formed inside. The water inlet 312 is provided at the top of the upper housing 31 and the water inlet 312 is arranged vertically. The water outlet 313 is provided at the side of the upper housing 31 and the water outlet 313 is arranged horizontally. The lower housing 33 is connected to the bottom of the upper housing 31. The drive motor 34 is arranged vertically and installed at the bottom of the lower housing 33. A first installation chamber 331 is formed inside the lower housing 33. The output shaft 341 of the drive motor 34 extends into the first installation chamber 331 and is used for transmission connection with the impeller 32.

[0038] Therefore, by arranging the drive motor 34 vertically, that is, the centrifugal pump 3 is arranged vertically, the water inlet 312, the upper shell 31, the impeller 32 and the drive motor 34 are all coaxially arranged in the vertical direction, so that the water inlet channel 3121 and the pump chamber 311 are interconnected in the vertical direction; with such an arrangement, when the centrifugal pump 3 is started and the impeller 32 is driven to rotate, under high-speed rotation, the boiled water begins to boil and generate water vapor, and the water vapor is less affected by the centrifugal force, so it is easy to gather at the side position of the pump chamber 311. Since the water inlet channel 3121 is connected with the pump chamber 311 in the axial direction, the water vapor can flow upward along the axial direction and be discharged into the water inlet channel 3121, thereby avoiding the occurrence of air binding, thereby ensuring the normal operation of the centrifugal pump 3 to achieve smooth water discharge.

[0039] Specifically, the upper shell 31 is rectangular and has four corners with first mounting holes 314. Correspondingly, the lower shell 33 is provided with second mounting holes 332 corresponding to the first mounting holes 314. Thus, the connection between the upper shell 31 and the lower shell 33 can be achieved by passing a locking screw 38 through the first mounting hole 314 and fixing it in the second mounting hole 332. Preferably, the first mounting hole 314 is a through hole, and the second mounting hole 332 is a screw hole.

[0040] Similarly, the lower shell 33 is also provided with a third mounting hole 333 located in the first mounting cavity 331, and the drive motor 34 is provided with a fourth mounting hole 342 at a position corresponding to the third mounting hole 333; thus, the connection between the lower shell 33 and the drive motor 34 can be achieved by passing a locking screw 38 through the third mounting hole 333 and fixing it in the fourth mounting hole 342; preferably, the third mounting hole 333 is a through hole, and the fourth mounting hole 342 is a screw hole.

[0041] Furthermore, the output shaft 341 of the drive motor 34 and the impeller 32 are connected in transmission via a magnetic attraction component, which includes an active magnetic ring 37 sleeved on the output shaft 341 and located in the first mounting cavity 331, and a driven magnetic ring 39 arranged in the impeller 32 and adsorbed with the active magnetic ring 37, and the active magnetic ring 37 and the driven magnetic ring 39 are non-contactly matched.

[0042] Specifically, a magnetic ring fixing sheet 371 and a shaft sleeve 372 connected to the magnetic ring fixing sheet 371 are further provided in the first installation cavity 331, the active magnetic ring 37 is fixed on the magnetic ring fixing sheet 371, and the shaft sleeve 372 is fixedly sleeved on the output shaft 341. Therefore, when the drive motor 34 is started and the output shaft 341 is driven to rotate, the shaft sleeve 372 and the magnetic ring fixing sheet 371 can be used to drive the active magnetic ring 37 to rotate, and then drive the driven magnetic ring 39 to rotate to realize the rotation of the impeller 32.

[0043] Furthermore, it also includes a sealing plate 35 arranged between the upper shell 31 and the lower shell 33 and used to separate the pump chamber 311 from the first installation chamber 331. The upper end of the sealing plate 35 is integrally formed with a fixed shaft 351. The impeller 32 is sleeved on the fixed shaft 351 and can rotate around the axial direction of the fixed shaft 351.

[0044] Specifically, the impeller 32 includes an impeller body and an impeller internal component 321 disposed on the impeller body, and the impeller internal component 321 is sleeved on the fixed shaft 351; wherein a second mounting cavity is provided in the impeller body, and the driven magnetic ring 39 is disposed in the second mounting cavity and connected to the impeller internal component 321 through a magnetic ring transmission sheet 391. Therefore, when the driven magnetic ring 39 is driven to rotate, the impeller body can be driven to rotate through the magnetic ring transmission sheet 391 and the impeller internal component 321.

[0045] Among them, a convex column 3211 is integrally formed at the upper end of the impeller internal component 321, and a limiting block 3122 is also integrally formed in the water inlet 312, and the top of the convex column 3211 is close to or in conflict with the bottom of the limiting block 3122; with such an arrangement, when the impeller internal component 321 moves up and down during rotation, the convex column 321 and the limiting block 3122 can be provided to limit the impeller internal component 321, thereby limiting the impeller 32 to prevent it from deviating.

[0046] Furthermore, it also includes a sealing ring 36 disposed between the sealing plate 35 and the upper shell 31. When the upper shell 31 and the lower shell 33 are connected up and down, the sealing ring 36 abuts against the upper shell 31 and the lower shell 33 respectively to achieve waterproof sealing.

[0047] In summary, the utility model provides a water bottle with smooth water flow, which arranges the water inlet 312 on the pump housing, the pump housing and the impeller 32 coaxially, so that the water inlet channel 3121 and the pump chamber 311 are interconnected in the axial direction, and the water vapor accumulated in the pump chamber 311 can be directly discharged into the water inlet channel 3121, thereby avoiding the occurrence of air binding and ensuring smooth water flow.
