Description

Technical Field

[0001] This utility model relates to the field of water pump technology, and more specifically to a rechargeable split-type electric bottled water pump. Background Technology

[0002] Existing electric water pumps for bottled water mainly fall into two design categories: one integrates the spout with the main unit, with the spout fixed to the casing and non-removable; the other uses a stainless steel tube as the spout, which can be removed when not in use. Both designs have the following problems: the integrated design makes the spout inconvenient to clean and maintain, posing hygiene risks. Furthermore, this design is bulky, hindering product transportation and user portability. While the stainless steel tube structure is detachable, its complex mold structure requires high precision, resulting in high production costs. Current electric water pumps typically use screws or other methods for assembly, which is cumbersome, inefficient, and prone to leakage during use. Therefore, existing electric water pumps are inadequate in terms of ease of use, hygiene, production cost, and portability, necessitating an improved technical solution to overcome these shortcomings.

[0030] Please refer to a rechargeable, split-type electric bottled water pump. Figure 1-9 This utility model is a device specifically designed for pumping bottled drinking water, commonly used in homes, offices, or other places, to facilitate the extraction of water from large bottles. The utility model includes a main pump unit 100 and a detachable spout 200 connected to the main pump unit 100. The main pump unit 100 includes a housing 110 and a water pump 160 inside the housing 110 for pumping water. The main pump unit 100 is generally installed at the opening of the bottled water container, connected to and extending into the bottled water via a flexible hose. The water pump 160 pumps the water from the bottled water and it flows out through the spout 200 for the user to drink. The housing 110 has an assembly hole 111, and the spout 200 has an outlet 221 and an inlet 222 that matches the assembly hole 111. The spout 200 is connected to the main pump unit 100 via an interference fit between the inlet and the assembly hole 111. This interference fit prevents leakage during water extraction, and the plug-in installation allows for easy assembly and disassembly of the spout 200. The water outlet 200 and the water pump main unit 100 can be manufactured as independent components. Users can easily assemble the water outlet 200 onto the water pump main unit 100. The detachable structure of the water outlet 200 and the water pump main unit 100 can reduce the packaging volume of the product, making it easy to transport and carry.

[0031] The water outlet 200 includes an upper cover 210 and a lower cover 220. The lower cover 220 has a limiting inner ring 223 and a limiting outer ring 224. The upper cover 210 has an inner ring rib 211 that mates with the limiting inner ring 223 and the limiting outer ring 224. The inner ring rib 211 can be interference-fitted between the limiting inner ring 223 and the limiting outer ring 224 to form the water channel 201. The lower cover 220 has multiple mounting posts 225, and the upper cover 210 has multiple mounting sleeves 212 corresponding to the mounting posts 225. The upper cover 210 and the lower cover 220 are fixedly connected by the mounting posts 225 embedded in the mounting sleeves 212. The mounting sleeves 212 and the mounting posts 225 are interference-fitted, so that the upper cover 210 and the lower cover 220 can be directly snapped together and fixed without the use of screws or other processing methods, which facilitates assembly and production. A groove matching the inner ring 211 is formed between the inner ring 223 and the limiting inner ring 223. When the upper cover 210 and the lower cover 220 are fastened together, the inner ring 211 is embedded between the inner ring 223 and the limiting inner ring 223. Figure 9 The inner limiting ring 223 and the inner limiting ring 223 wrap around the inner ring rib 211 on both sides and are press-fitted to achieve a double sealing effect, which can effectively prevent water leakage. The inner limiting ring 223 and the inner limiting ring 223 protrude into the interior of the lower cover 220, and the inner ring rib 211 protrudes into the interior of the upper cover 210. The inner limiting ring 223 and the inner limiting ring 223 wrap around the inner ring rib 211 on both sides, forming the water passage 201 inside. The water outlet 221 and the water inlet 222 are respectively located at the bottom of the lower cover 220 inside the inner limiting ring 223, so that the water outlet 221 and the water inlet 222 are connected through the water passage 201.

[0032] Furthermore, the bottom of the outer casing 110 is provided with a bottom cover 120, which is connected to the water pump 160. The main unit 100 of the water pump is provided with an adapter 130 that can connect the bottom cover 120 to the water outlet 200. The bottom cover 120 is provided with a bottom cover inlet end 121 that runs through the top and bottom. The upper and lower ends of the bottom cover inlet end 121 protrude from the bottom cover 120 respectively. The part of the bottom cover inlet end 121 that protrudes below the bottom cover 120 can be connected to a flexible hose that extends into the bottled water, while the part of the bottom cover inlet end 121 that protrudes above the bottom cover 120 is connected to the water pump 160. The bottom cover 120 is provided with a bottom cover outlet end 122 and a connecting hole 123 that are interconnected. The bottom cover outlet end 122 and the connecting hole 123 are connected to form a connection. The L-shaped pipe structure has an upward-facing connection hole 123 for connecting the water pump 160, while the bottom cover outlet 122 faces towards the side wall of the outer casing 110 and is used to connect the adapter 130. The bottom of the water pump 160 is provided with an outlet interface and an inlet interface that match the connection hole 123 and the bottom cover inlet interface 121, respectively. The water pump 160 is fixedly installed on the bottom cover 120 by embedding the outlet interface and the inlet interface into the connection hole 123 and the bottom cover inlet interface 121, respectively. The bottom cover inlet interface 121 and the connection hole 123 are respectively provided with sealing rings 101 to seal the connection of the water pump 160, so as to ensure a sealed connection between the water pump 160 and the bottom cover 120 and avoid water leakage during the pumping process.

[0033] Furthermore, the adapter 130 has a hollow pipe structure. One end of the adapter 130 is provided with an adapter inlet 131 that can be connected to the water outlet 122 of the bottom cover, and the other end is provided with an adapter outlet 132 that can be embedded in and protrude from the assembly hole 111. The adapter 130 has an "L" shaped structure. The adapter inlet 131 is horizontally embedded in the water outlet 122 of the bottom cover with the adapter outlet 131 facing upward. When the outer shell 110 is connected to the bottom cover 120, the adapter outlet 131 is embedded in the assembly hole 111 and protrudes. When the water outlet 200 is installed, the water outlet inlet 222 of the water outlet is embedded in the assembly hole 111, and at the same time, the adapter outlet 131 is embedded in the water outlet inlet 222 of the water outlet to complete the connection and installation of the adapter 130. The adapter 130 is interference-fitted with the water inlet end 222 of the water outlet, the assembly hole 111, and the water outlet end 122 of the bottom cover to achieve a sealed connection. By designing a structure in which each component can be connected to each other, the water pump 160, the adapter 130, and the water outlet 200 can all be connected by interference fit plug-in method, which greatly reduces the difficulty of assembly and improves the efficiency of product production and processing.

[0034] Furthermore, the main unit 100 of the water pump is equipped with a circuit board 140 connecting the water pump 160 and a lithium battery 150. The water pump 160 is controlled to operate via the circuit board 140, and the lithium battery 150 provides power to the water pump, eliminating the need for an external power source. Typically, the outer casing 110 has a switch button connected to the circuit board 140, which the user uses to turn on the water pump. Figure 4 As shown, the arrows inside the water pump indicate the direction of water flow. When the water pump is started, water from the bottled water enters from the bottom cover inlet 132, the water pump 160 enters from the bottom cover outlet 122, enters the adapter inlet 132 of the adapter 130, flows from the adapter outlet 132 into the outlet 200, and finally flows out from the outlet 221 of the outlet 200, so that the user can collect the flowing water for drinking.
