Description

Technical Field

[0001] The utility model relates to a portable folding-arm electric water pump, which is applied to the field of water pumps. Background Art

[0002] A water dispenser pump is a device used to pump water from a water storage container to the outlet of a water dispenser. This pump is usually used in water dispensers in homes, offices or public drinking water areas to facilitate users to obtain drinking water. The working principle of a water dispenser pump is that it is driven by an electric motor, which generates negative pressure by rotating the impeller to pump water from the container and transport it to the outlet.

[0003] In order to prevent infection at the water outlet, the existing water dispenser pump usually sets the water outlet arm in a foldable storage form. When not in use, the water outlet is stored inside the shell to prevent infection. However, the existing folding and storage method is usually not fixed, which will cause the water outlet arm to move at will, resulting in infection at the water outlet. Alternatively, a snap-fit method is used. Although this method can effectively fix the water outlet arm, it may be inconvenient to fold or unfold it, and as the number of uses increases, the snap may be worn, loosened, or broken, etc., and the entire shell needs to be replaced, which increases the cost. Therefore, in order to address one or more of the above problems, the utility model designs a portable folding-arm electric water pump. Utility Model Content

[0031] Reference Figures 1-5 As shown, a portable folding arm electric water pump comprises a water pumping housing 10 with a built-in water pumping device 30, a placement groove 11 is arranged on the side wall of the water pumping housing 10 in the vertical direction, a water outlet arm 20 is hinged on the top side wall of the placement groove 11, and the water outlet arm 20 and the water pumping housing 10 have an unfolded state / folded state, and a water outlet nozzle 21 is arranged at the other end of the water outlet arm 20, and the water outlet nozzle 21 is connected to the water pumping device 30 for pumping water.

[0032] A first through groove 12 penetrating through the interior of the water pumping housing 10 is provided at the top of the placement groove 11, a first magnetic member 13 is provided on the inner side wall of the water pumping housing 10, a hinged end 22 rotatably connected to the water pumping housing 10 is provided at the top of the water outlet arm 20, a buckling portion 23 adapted to the first through groove 12 is provided above the hinged end 22, a second through groove 231 is provided at the top of the buckling portion 23, a second magnetic member 24 corresponding to the first magnetic member 13 is provided in the second through groove 231, and a third magnetic member 25 corresponding to the first magnetic member 13 is provided on the inner side wall below the hinged end 22;

[0033] When the water outlet arm 20 is in the unfolded state, the buckle portion 23 is disposed in the first through groove 12, so that the first magnetic member 13 and the second magnetic member 24 are magnetically fixed to facilitate water pumping;

[0034] When the water outlet arm 20 is in a folded state, the water outlet arm 20 is disposed in the placement groove 11, so that the first magnetic element 13 and the third magnetic element 25 are magnetically fixed, which facilitates the storage of the water outlet arm and prevents the water outlet 21 from being infected with bacteria and viruses.

[0035] Reference Figure 5 As shown, the height of the buckle part 23 is higher than the height of the water pumping housing 10, so the water outlet arm 20 can be opened by pushing the buckle part 23 backwards, which is convenient for users to use.

[0036] Reference Figures 6-7 As shown, a pair of sliding mounting grooves 232 are arranged in the second through groove 231, and a retaining edge 241 corresponding to the sliding mounting groove 232 is arranged on the side wall of the second magnetic attraction member 24. In the present embodiment, the second magnetic attraction member 24 is a magnetic sheet, and the retaining edge 241 is arranged in the sliding mounting groove 232 to fix the second magnetic attraction member 24. Since the second magnetic attraction member 24 is arranged in the second through groove 231 and is fixed by the retaining edge 241 arranged in the sliding mounting groove 232, the second magnetic attraction member 24 can be easily replaced without disassembly.

[0037] Reference Figures 2-5As shown, a first mounting groove 131 is provided on the inner side wall of the water pumping housing 10 near one end of the first through groove 12, and a first magnetic member 13 is provided in the first mounting groove 131, and the first magnetic member 13 is easy to replace, and a second mounting groove 251 is provided inside the end of the water outlet arm 20 near the buckling portion 23, and a third magnetic member 25 is provided in the second mounting groove 251. In this embodiment, the first magnetic member 13 and the third magnetic member 25 are magnetic blocks, and the magnetic fixing method of the utility model is fixed by a magnetic member arranged near the hinge end 22, and because the third magnetic member 25 is arranged inside the water outlet arm 20, the magnetism between the third magnetic member 25 and the first magnetic member 13 is weaker than the magnetism between the second magnetic member 24 and the first magnetic member 13, because there are more barriers between the third magnetic member 25 and the first magnetic member 13, The advantage of such a configuration is that since the utility model opens the water outlet arm 20 by pushing the snap-fit portion 23 backwards, according to the lever principle, at this time, the method of opening the water outlet arm 20 is relatively laborious, so the magnetism between the third magnetic component 25 and the first magnetic component 13 is relatively weak, which facilitates the opening of the water outlet arm 20; and when folding the water outlet arm 20, the water outlet arm 20 can be stored by pressing the front end of the water outlet arm 20. According to the labor-saving lever principle, it is easier to accidentally touch the water outlet arm 20 during use, causing it to bend, thereby affecting the direction of water outlet, and water may spill all over the ground. Therefore, the magnetism between the second magnetic component 24 and the first magnetic component 13 is relatively strong, so that the installation and fixation of the water outlet arm 20 when it is unfolded is more firmly. The utility model can achieve the installation and fixation of the water outlet arm 20 by arranging a magnetic component on the water pumping shell 10, which can effectively save costs.

[0038] The hinged end 22 is a flange 221 symmetrically arranged on both sides of the water outlet arm 20, and one side of the flange 221 is arranged to be inclined. The advantage of such arrangement is that the water outlet arm 20 can be easily disassembled or installed. The flange 221 is provided with a through hole 222 penetrating the water outlet arm 20 along its axial direction, and the water pumping housing 10 is provided with a mounting hole 14 corresponding to the flange 221, and the flange 221 is arranged in the mounting hole 14.

[0039] As a further improvement, the pumping device 30 includes a mounting seat 31 provided at the bottom of the pumping housing 10. A water inlet hole 311 is provided in the middle of the mounting seat 31. Above the water inlet hole 311, a water pump 32 is fixedly provided. The water pump 32 includes a pump body 321 communicating with the water inlet hole 311. Above the pump body 321, a driving motor 322 is provided. A water outlet hole 323 is provided on the side wall of the pump body 321. The water outlet hole 323 is communicated with the water outlet nozzle 21 through a water pipe (not shown in the figure). In the present utility model, rotation is performed through the convex edge 221, and the water pipe passes through the through hole 222 to connect the water outlet hole 323 and the water outlet nozzle 21. The advantage of such a setting is that during the process of storing and folding the water outlet arm 20, the water pipe does not move along with the water outlet arm 20, making the installation of the water pipe more firm and preventing it from loosening.

[0040] According to Figure 3 、 Figure 5 As shown, above the driving motor 322, a control panel 33 is installed. A plurality of buttons 331 are provided on the control panel 33. Above the pumping housing 10, a plurality of control buttons 15 corresponding to the buttons 331 are provided. The control buttons 15 abut against the buttons 331 to control the pumping. In this embodiment, the control buttons 15 include functions such as water outlet, quantitative water outlet, and shutdown.

[0041] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
