Description

Technical Field

[0001] The utility model relates to the technical field of water bottles, in particular to a novel anti-evacuation water discharge structure and a water bottle having the same. 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] Existing centrifugal pumps transport liquids using the centrifugal force generated by the rotation of the impeller. When the impeller rotates rapidly, the fluid trapped between the blades rotates with it. Centrifugal force forces the fluid out through the grooves between the blades and out the outlet on the pump casing. This outflow of fluid creates a vacuum at the impeller inlet, where the external fluid is automatically drawn into the impeller under atmospheric pressure. This process repeats continuously, achieving continuous fluid delivery.

[0004] Among them, when the centrifugal pump is applied to a kettle, the boiled water in the kettle rotates with the impeller. Under high-speed rotation, the boiled water begins to boil and produces water vapor. The density of the water vapor becomes smaller and is less affected by the centrifugal force. It cannot be discharged from the water outlet on the pump casing along with the water flow, thus producing an "air binding" phenomenon, resulting in the inability to inhale and replenish the water flow, thereby causing a vacuum phenomenon, and then the water flow becomes not smooth or the flow is interrupted. Utility Model Content

[0005] In order to overcome the defects of the above-mentioned prior art, the utility model provides a novel anti-vacuum drainage structure and a water bottle having the same. A turbine is arranged at the connection between the water inlet of the pump casing and the water outlet hole of the inner tank. When the impeller rotates to realize water discharge, the turbine can rotate with the flow of water, thereby accelerating the drainage speed, and then pressurizing the water inlet of the pump casing, thereby reducing the generation of water vapor. At the same time, accelerating the drainage speed is also more conducive to the discharge of air in the pump casing, thereby avoiding the problem of smooth water discharge or no water discharge, and thus ensuring that the centrifugal pump can work normally.

[0006] The technical solution adopted by the present invention to solve the problem is:

[0007] A new type of anti-evacuation launching structure, comprising:

[0008] An inner tank, the bottom of which is provided with a water outlet;

[0010] Wherein, a turbine is further provided at the connection point between the water inlet and the water outlet, and the turbine can rotate along with the flow of water.

[0011] Furthermore, it also includes a downpipe arranged between the water outlet and the water inlet and connected to both of them, and the turbine is rotatably arranged in the downpipe.

[0012] Furthermore, it also includes a filter screen arranged at the water outlet, a fixed shaft extending into the interior of the sewer pipe is provided at the bottom of the filter screen, and the turbine is rotatably mounted on the fixed shaft.

[0013] Furthermore, it also includes a limiting ring arranged on the fixed shaft, and the turbine abuts against the limiting ring to achieve limiting.

[0014] Furthermore, the fixed shaft, the downpipe and the water inlet are all coaxially arranged.

[0015] Furthermore, the filter screen and the fixed shaft are integrally formed.

[0016] Furthermore, it also includes a mounting base connected to the rear end of the pump housing and a drive motor mounted on the mounting base, wherein:

[0017] A mounting cavity is formed inside the mounting seat, and the output shaft of the drive motor extends into the mounting cavity;

[0018] The output shaft and the impeller are connected in transmission via a magnetic attraction structure.

[0019] Furthermore, the magnetic attraction structure includes an active magnetic ring sleeved on the output shaft and located in the installation cavity, and a driven magnetic ring arranged in the impeller and magnetically matched with the active magnetic ring;

[0020] When the driving motor is started and drives the output shaft to rotate, the impeller can be driven to rotate through the magnetic attraction cooperation between the active magnetic ring and the driven magnetic ring.

[0021] Furthermore, it also includes a partition plate arranged between the pump casing and the mounting seat and separating the pump cavity from the mounting cavity. One end of the partition plate is provided with a shaft body extending into the pump cavity, and the impeller is rotatably mounted on the shaft body.

When the impeller rotates to realize water discharge, the turbine can rotate with the flow of water, thereby accelerating the drainage speed, and then realizing pressurization at the water inlet of the pump casing, thereby reducing the generation of water vapor. At the same time, accelerating the drainage speed is also more conducive to the discharge of air in the pump casing, thereby avoiding the problem of smooth water discharge or no water discharge, thereby ensuring that the centrifugal pump can work normally.

They 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 orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art 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.

[0035] Example 1

[0036] See Figure 1-5 The present invention provides an anti-evacuation and drainage structure 1 for use in a water bottle, which includes an inner liner 11 and a centrifugal pump 12 arranged below the inner liner 11. A water outlet 111 is provided at the bottom of the inner liner 11. The centrifugal pump 12 is arranged horizontally and includes a pump housing 121 and an impeller 122 arranged in the pump housing 121. A pump cavity 1213 is formed inside the pump housing 121. The impeller 122 is rotatably arranged in the pump cavity 1213 and is coaxially arranged with the pump housing 121. The front end of the pump housing 121 is also provided with a water inlet 1211 arranged perpendicular to its axis and opening upward, and the water inlet 1211 is connected to the pump cavity 1213 and the water outlet 111 respectively. In addition, a water outlet 1212 is also provided on the side of the pump housing 121, and the water outlet 1212 is connected to the pump cavity 1213. Preferably, the water outlet 1212 is arranged perpendicular to the water inlet 1211.

[0037] Therefore, during the normal operation of the centrifugal pump 12, by driving the impeller 122 to rotate, the impeller 122 rotates to form a negative pressure in the pump chamber 1213, and the water in the inner tank 11 can be discharged from the water outlet 111 and enter the pump chamber 1213 through the water inlet 1211. At the same time, under the action of the centrifugal force of the impeller 122, the water in the pump chamber 1213 can be discharged through the water outlet 1212.

[0038] The connection between the water inlet 1211 of the pump housing 121 and the water outlet 111 of the inner tank 11 is provided with a turbine 13, which can rotate with the flow of water. Specifically, a downpipe 14 is provided at the bottom of the inner tank 11 and between the water outlet 111 and the water inlet 1211. The downpipe 14 is connected to the water outlet 111 and the water inlet 1211, respectively, and the turbine 13 is rotatably disposed within the downpipe 14.

[0039] Therefore, by arranging the turbine 13 in the sewer pipe 14, when the impeller 122 rotates to realize water discharge, the turbine 13 can rotate with the flow of water, thereby accelerating the water discharge speed, and then achieving pressurization at the water inlet 1211 of the pump casing 121, thereby reducing the generation of water vapor. At the same time, accelerating the water discharge speed is also more conducive to the discharge of air in the pump casing 121, thereby avoiding the problem of smooth water discharge or no water discharge, thereby ensuring that the centrifugal pump 12 can work normally.

[0040] Furthermore, the device further includes a filter screen 15 disposed at the water outlet 111 of the inner tank 11. A fixed shaft 151 extending into the interior of the downpipe 14 is provided at the bottom of the filter screen 15. The turbine 13 is rotatably mounted on the fixed shaft 151. Furthermore, a retaining ring 16 is provided at the bottom of the fixed shaft 151. The bottom of the turbine 13 abuts against the retaining ring 16 to achieve positional retention.

[0041] Preferably, the limiting ring 16 can be connected to the fixed shaft 151 by a detachable connection method such as a threaded connection, a snap connection, etc., so that the turbine 13 can be quickly assembled and disassembled, thereby facilitating its maintenance and replacement.

[0042] Furthermore, a first sealing ring 17 is included, which is arranged between the sewer pipe 14 and the bottom wall of the inner tank 11 to form a waterproof seal, thereby improving the sealing and waterproof performance of the sewer structure.

[0043] In the embodiment of the present invention, the filter screen 15 and the fixed shaft 151 are integrally formed, thereby making the structure more stable.

[0044] In the embodiment of the present invention, the fixed shaft 151 , the downpipe 14 and the water inlet 1211 of the pump housing 121 are all coaxially arranged.

[0045] See also Figure 3-4 The centrifugal pump 12 also includes a mounting base 123 connected to the rear end of the pump casing 121 and a drive motor 124 mounted on the mounting base 123, wherein a mounting cavity 1231 is formed inside the mounting base 123, and the output shaft of the drive motor 124 extends into the mounting cavity 1231; the output shaft of the drive motor 124 and the impeller 122 are connected to each other through a magnetic structure.

[0046] Specifically, the magnetic structure includes an active magnetic ring 125 that is sleeved on the output shaft and located in the installation cavity 1231, and a driven magnetic ring 128 that is arranged in the impeller 122 and magnetically cooperates with the active magnetic ring 125; thus, when the drive motor 124 is started and the output shaft is driven to rotate, the impeller 122 can be driven to rotate through the magnetic cooperation between the active magnetic ring 125 and the driven magnetic ring 128.

[0047] Furthermore, the pump housing 121 further includes a partition 126 disposed between the pump housing 121 and the mounting seat 123 and used to separate the pump cavity 1213 from the mounting cavity 1231. A shaft 1261 extending into the pump cavity 1213 is integrally formed at the front end of the partition 126. The impeller 122 is sleeved on the shaft 1261 and can rotate around the shaft 1261. Furthermore, a second sealing ring 127 is disposed between the partition 126 and the pump housing 121. When the pump housing 121 is connected to the mounting seat 123, the second sealing ring 127 can abut against the pump housing 121 and the partition 126, respectively, to achieve a waterproof seal, thereby preventing water from entering the mounting seat 123.

[0048] Of course, in other embodiments, a third sealing ring may be provided between the partition 126 and the mounting seat 123 to achieve a waterproof seal, thereby further improving the waterproof performance of the centrifugal pump 12 .

[0049] Example 2

[0050] See Figure 6 The present invention further provides a water bottle, comprising the anti-evacuation drainage structure 1 of the first embodiment and a water outlet pipe 2, wherein the water outlet pipe 2 is connected to the water outlet 1212 on the pump housing 121. Thus, when the centrifugal pump 12 is started, the boiled water in the inner tank 11 can be pumped out and sequentially flows through the drain pipe 14, the water inlet 1211, the pump chamber 1213, the water outlet 1212 and the water outlet pipe 2 for drinking by the user.

[0051] In summary, the utility model provides a new anti-vacuum drainage structure 1 and a water bottle having the same, by arranging a turbine 13 at the connection between the water inlet 1211 of the pump casing 121 and the water outlet 111 of the inner tank 11. When the impeller 122 rotates to realize water discharge, the turbine 13 can rotate with the flow of water, thereby accelerating the drainage speed, and then realizing pressurization at the water inlet 1211 of the pump casing 121, thereby reducing the generation of water vapor. At the same time, accelerating the drainage speed is also more conducive to the discharge of air in the pump casing 121, thereby avoiding the problem of smooth water discharge or no water discharge, thereby ensuring that the centrifugal pump 12 can work normally.
