Description

Technical Field

[0001] The utility model belongs to the technical field of water pumps and relates to a water pump structure with a rotatable base. Background Art

[0002] Submersible pumps generally have two water intake methods: one is to let water in through the filter on the base. When the base filter is letting water in, the submersible pump is placed at the bottom of the pool, and the water at the bottom of the pool is filtered through the filter and then enters the pump; the other is to let water in through a connected hose. When the hose is letting water in, a float will be set at the water inlet of the hose to ensure that the inlet of the hose is in the middle and upper layers of the water layer in the pool. This water intake mode can ensure that the water entering the pump is relatively clean.

[0003] When the existing submersible pump switches between the two water inlet modes, it is achieved by removing the base, which is not only very troublesome, but the removed base is also easy to lose and needs to be kept separately. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a water pump structure with a rotatable base, which can more conveniently switch the water inlet mode of the water pump.

[0005] In order to solve the above technical problems, the purpose of the utility model is achieved through the following technical solutions:

[0007] The base rotates to switch the water inlet mode of the water pump;

[0008] In the water inlet mode of the base, the upper opening and the lower opening are staggered, the water inlet filter is connected to the upper opening, and the inside of the base is not connected to the lower opening;

[0009] In the pipe water inlet mode, the upper opening and the lower opening are co-located, the water inlet pipe is connected to the pipe joint and communicated with the upper opening, and the upper opening is not communicated with the inside of the base.

[0010] In the above-mentioned water pump structure with a rotatable base, the staggered distribution means that there is no overlapping part between the two openings; and the co-location distribution means that the two openings at least partially overlap to expose the pipe joint.

[0011] In the above-mentioned water pump structure with a rotatable base, when the pipe joint is formed below the upper opening:

[0012] Furthermore, the pipe joint is provided with an external thread connected to the water inlet pipe, the radial dimension of the lower opening is larger than the radial dimension of the upper opening, and the axial dimension of the pipe joint is smaller than the axial dimension inside the base.

[0013] Furthermore, a limiting convex block and a limiting convex ring are provided at the bottom of the pump body, and a limiting rib is provided on one side of the lower opening; when the base rotates to the pipe water inlet mode, the limiting rib abuts against the limiting convex block; when the base rotates to the base water inlet mode, the limiting rib abuts against the limiting convex ring, and the limiting convex ring seals the lower opening. Preferably, the radial dimension of the limiting convex ring is greater than the radial dimension of the lower opening, and the bottom of the limiting convex ring abuts against the base outside the lower opening to form a sealing structure.

[0014] In the above-mentioned water pump structure with a rotatable base, when the pipe joint is formed above the lower opening:

[0015] Furthermore, the pipe joint is provided with an internal thread for connecting to the water inlet pipe, and the upper end surface of the pipe joint is sealedly connected to the bottom of the pump body. Preferably, the inner diameter of the pipe joint is the same as the radial dimension of the upper opening.

[0016] Furthermore, limiting protrusions are respectively provided on both sides of the bottom of the pump body, and limiting ribs are respectively provided on both sides of the lower opening; when the base is rotated to the tube water inlet mode, one limiting rib abuts against a limiting protrusion; when the base is rotated to the base water inlet mode, another limiting rib abuts against another limiting protrusion.

[0017] In the above-mentioned water pump structure with a rotatable base, the base is sealed and connected to the pump body via a stop structure.

[0018] In the above-mentioned water pump structure with a rotatable base, the switching angle between the base water inlet mode and the pipe water inlet mode is 180°. Preferably, when the upper opening and the lower opening are coaxial, they are coaxial.

[0019] In the above-mentioned water pump structure with a rotatable base, a coaxial first convex ring is arranged at the bottom of the pump body, and a coaxial second convex ring is arranged above the base, and the first convex ring is sleeved on the second convex ring.

[0020] In the above-mentioned water pump structure with a rotatable base, an internal threaded column inserted into the second convex ring is arranged in the first convex ring, and a special-shaped flat gasket is fixed to the bottom of the internal threaded column by screws, and the special-shaped flat gasket includes a circular portion and fan-shaped portions extending outwardly from both sides of the circular portion, and a pair of inwardly extending limit clamps are arranged on the second convex ring, and the limit clamps interfere with the fan-shaped portion when they are rotated to the relative position of the fan-shaped portion.

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] 1. The utility model provides a water pump structure with a rotatable base. By rotating the base, the water pump can be switched between two water inlet modes. When the upper opening and the lower opening are rotated to a misaligned position, the water inlet channel of the tube is closed, and water enters through the base at this time; when the upper opening and the lower opening are rotated to the same position, the water inlet channel of the base is closed, and water enters through the water inlet pipe at this time. Therefore, when switching the water inlet mode, the utility model does not need to remove the base, and the switching is more convenient.

[0023] 2. The utility model improves the disassembly and assembly structure of the base on the basis of the rotating base, and adopts the cooperation of the special-shaped flat gasket and the limiting structure. Similarly, the base can be conveniently disassembled by rotating the base. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The present invention will be further described below with reference to the accompanying drawings. Figure 1-11 :

[0037] Example 1

[0038] Compare with Figure 1-5

[0039] A water pump structure with a rotatable base 2, comprising a pump body 1 and a base 2, wherein the base 2 is rotatably connected to the bottom of the pump body 1, a water inlet filter 3 is circumferentially arranged on the base 2, an upper opening 4 is eccentrically arranged at the bottom of the pump body 1, a lower opening 5 is eccentrically arranged at the bottom of the base 2, and a pipe joint 6 is formed below the upper opening 4;

[0040] When in use, the water inlet mode of the water pump is switched by rotating the base 2:

[0041] In the water inlet mode of the base 2, the upper opening 4 and the lower opening 5 are staggered, and the water inlet filter 3 is connected to the upper opening 4; Figure 2 In this mode, the water in the pool enters the base 2 through the water inlet filter 3, and then enters the pump body 1 through the pipe joint 6 and the upper opening 4. The base 2 is not connected to the lower opening 5, and water cannot enter through the lower opening 5;

[0042] In the pipe water inlet mode, the upper opening 4 and the lower opening 5 are co-located, the water inlet pipe is connected to the pipe joint 6 and communicated with the upper opening 4. Figure 3 In this mode, the water in the pool is sucked in by the water inlet pipe, and then enters the pump body 1 through the pipe joint 6 and the upper opening 4. The upper opening 4 is not connected to the inside of the base 2, and water cannot enter through the water inlet filter 3 and the inside of the base 2.

[0043] In order to facilitate the connection of the water inlet pipe, the pipe joint 6 is provided with an external thread for connecting the water inlet pipe. The radial dimension of the lower opening 5 is larger than the radial dimension of the upper opening 4. In order to facilitate the water inside the base 2 to easily enter the pipe joint 6 when the base 2 is in the water inlet mode, the axial dimension of the pipe joint 6 is smaller than the axial dimension inside the base 2.

[0044] Furthermore, in order to switch the water inlet mode more accurately, the bottom of the pump body 1 is provided with a limiting protrusion 7 and a limiting protrusion ring 8, and one side of the lower opening 5 is provided with a limiting rib 9; when the base 2 rotates to the pipe water inlet mode, the limiting rib 9 conflicts with the limiting protrusion 7; when the base 2 rotates to the base 2 water inlet mode, the limiting rib 9 conflicts with the limiting protrusion 8, and the limiting protrusion ring 8 seals the lower opening 5. Preferably, the radial dimension of the limiting protrusion ring 8 is greater than the radial dimension of the lower opening 5, and the bottom of the limiting protrusion ring 8 conflicts with the base 2 outside the lower opening 5 to form a sealing structure.

[0045] In order to ensure the stable rotation of the base 2 and prevent water leakage in the base 2, the base 2 is sealed and connected to the pump body 1 through a stop structure.

[0046] In this embodiment, the switching angle between the water inlet mode of the base 2 and the water inlet mode of the tube is 180°. Preferably, when the upper opening 4 and the lower opening 5 are coaxial, they are coaxial.

[0047] In order to obtain a more stable rotation structure, a coaxial first convex ring 10 is provided at the bottom of the pump body 1, and a coaxial second convex ring 11 is provided above the base 2. The first convex ring 10 is mounted on the second convex ring 11. When the base 2 is rotated, the second convex ring 11 rotates relative to the first convex ring 10.

[0048] On the basis of the rotating base 2, this embodiment further designs the disassembly and assembly structure of the base 2: the first convex ring 10 is provided with an internal threaded column 12 inserted into the second convex ring 11, and the bottom of the internal threaded column 12 is fixed with a special-shaped flat gasket 14 by a screw 13, and the special-shaped flat gasket 14 includes a circular portion 15, and fan-shaped portions 16 extending outward from both sides of the circular portion 15, and the second convex ring 11 is provided with a pair of inwardly extending limit clamps 17, and the limit clamps 17 are abutted against the fan-shaped portion 16 when they are rotated to the relative position of the fan-shaped portion 16.

[0049] When the base 2 is rotated, the second convex ring 11 rotates accordingly and changes its relative position with the special-shaped flat gasket 14. When the limiting clamp 17 rotates to the position corresponding to the fan-shaped portion 16 of the special-shaped flat gasket 14, the special-shaped flat gasket 14 forms an axial limiting structure of the base 2. At this time, the base 2 is in an installed state; when the limiting clamp 17 rotates to the position corresponding to the non-fan-shaped portion 16, the second convex ring 11 can move freely axially relative to the special-shaped flat gasket 14, that is, the base 2 can move freely axially relative to the pump body 1. At this time, the base 2 is in a disassembled state.

[0050] Preferably, the base 2 changes state every time it rotates 90°, such as: at 0°, the base 2 is in a disassembly state; at 90°, the base 2 is in a base 2 water inlet mode state; at 180°, the base 2 is in a disassembly state; at 270°, the base 2 is in a tube water inlet mode state.

[0057] In order to facilitate the connection of the water inlet pipe, the pipe joint 6 is provided with an internal thread for connecting the water inlet pipe, and the upper end surface of the pipe joint 6 is sealed and connected to the bottom of the pump body 1.
