Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a water pump. Background Art

[0002] The water pump can be used to pump bottled water and is commonly used in homes and offices to improve the convenience of using bottled water for users.

[0003] Existing water pumps generally include a main body and a water outlet arm, which is movably connected to the main body. Under different working conditions, the relative position between the water outlet arm and the main body will change. Usually, when the pumping function is used, the water outlet arm needs to extend outward relative to the main body. When idle, the water outlet arm will be retracted inward relative to the main body.

[0004] Typically, the water outlet arm and the main body are positioned using components such as springs and positioning beads. Although this can make the positions of the water outlet arm and the main body relatively fixed, the positioning structure is relatively complex and difficult to install, which is not conducive to reducing material and labor costs.

[0005] Therefore, further improvement is needed. Utility Model Content

[0006] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and to provide a water pump that can not only relatively fix the positions of the water pump body and the water outlet arm, but also reduce the difficulty of overall equipment assembly, thereby helping to reduce material costs and labor costs.

The shapes of the first groove and the second groove are similar and are distributed at different positions on the water outlet arm. When the water outlet arm extends outward relative to the water pump body, the first groove is connected and cooperated with the limiting protrusion; when the water outlet arm is retracted inward relative to the water pump body, the second groove is connected and cooperated with the limiting protrusion.

[0013] As a specific solution, the connection end of the limiting protrusion with the limiting recess is in an arc shape, and the first groove and the second groove are in an arc shape corresponding to the limiting protrusion.

[0014] As a specific solution, a receiving groove corresponding to the water outlet arm is provided on the outer side of the water pump body. When the water outlet arm is stored inwardly relative to the water pump body, the water outlet arm is engaged with the receiving groove.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] See also Figure 1-Figure 7 The present water pump comprises a water pump body 1 and a water outlet arm 2, the water outlet arm 2 is movably connected to the water pump body 1, and an elastic mechanism is provided between the water pump body 1 and the water outlet arm 2, the elastic mechanism comprises a limiting protrusion 11 and a limiting recess 21 respectively arranged on the water pump body 1 and the water outlet arm 2, the limiting protrusion 11 and / or the limiting recess 21 can be elastically deformed, and the limiting protrusion 11 and the limiting recess 21 are connected and matched to fix the relative position of the water pump body 1 and the water outlet arm 2, and the limiting protrusion 11 and the limiting recess 21 are connected and matched to make the water outlet arm 2 not easily shifted from the water pump body 1 during use, thereby improving the stability of the product, and no additional components such as springs and positioning beads are required, which simplifies the structure of the equipment, reduces the difficulty of installation, and is conducive to reducing material and labor costs.

[0029] Furthermore, the limiting protrusion 11 and the water pump body 1 are integrally formed by injection molding, and the limiting recess 21 and the water outlet arm 2 are integrally formed by injection molding. The limiting protrusion 11 and the limiting recess 21 do not need to be additionally assembled with the water pump body 1 and the water outlet arm 2, which further simplifies the overall structure of the water pump.

[0030] Furthermore, a hollow gap 12 is formed between the limiting protrusion 11 and the water pump body 1, which can further improve the elastic effect of the limiting protrusion 11 and make the connection effect between the limiting protrusion 11 and the limiting recess 21 more stable.

[0031] Furthermore, a rotating shaft is formed between the water outlet arm 2 and the water pump body 1. The water outlet arm 2 can swing around the rotating shaft and extend outward or retract inward relative to the water pump body 1. The user can adjust the relative position between the water outlet arm 2 and the water pump body 1 according to usage needs.

[0032] Furthermore, the limiting protrusion 11 is in the shape of a convex edge extending toward the upper side, and the limiting recess 21 includes a first groove 211 and a second groove 212. The shapes of the first groove 211 and the second groove 212 are similar and are distributed at different positions on the water outlet arm 2. When the water outlet arm 2 extends outward relative to the water pump body 1, the first groove 211 is connected and cooperated with the limiting protrusion 11; when the water outlet arm 2 is retracted inward relative to the water pump body 1, the second groove 212 is connected and cooperated with the limiting protrusion 11, so that the water outlet arm 2 can have good stability in both the states of extending outward or retracting inward relative to the water pump body 1.

[0033] Furthermore, the connection end of the limiting protrusion 11 with the limiting recess 21 is in an arc shape, and the first groove 211 and the second groove 212 are in an arc shape corresponding to the limiting protrusion 11, thereby improving the smoothness of the connection and separation process between the limiting protrusion 11 and the first groove 211 or the second groove 212. When the water outlet arm 2 is moved by manual control, it can also improve the user's feel.

[0034] Furthermore, a storage groove 13 corresponding to the water outlet arm 2 is provided on the outer side of the water pump body 1. When the water outlet arm 2 is stored inward relative to the water pump body 1, the water outlet arm 2 is engaged with the storage groove 13, which makes more reasonable use of the spatial position of the water pump body 1 and reduces the overall volume of the water pump when the water outlet arm 2 is in the stored state.

[0035] Furthermore, a hollow hole 23 is provided at the position of the rotating shaft of the water outlet arm 2, a water transport mechanism 3 is provided in the water pump body 1, the water outlet arm 2 has a water outlet nozzle 24, a water transport pipe is connected between the water outlet nozzle 24 and the water transport mechanism 3, and the water transport pipe passes through the hollow hole 23.

The water inlet end of the water transport mechanism 3 is provided with a water outlet nozzle 24, and the water outlet nozzle 24 extends outward through the limit cover 4. The limit cover 4 can make the connection between the water pump as a whole and the bottled water more convenient and stable.

[0037] Furthermore, an assembly opening 25 is provided on the outer side of the water outlet arm 2 , and a detachable cover plate 26 is connected to the assembly opening 25 , so as to facilitate installation or maintenance of the pipeline inside the water outlet arm 2 .
