[0033] See also Figures 1 to 4The embodiment of the utility model provides a water pump, which is placed at the water outlet of a household bottled water to extract water from the household bottled water. The water pump includes a housing assembly 1, a first power source assembly 2, and a second power source assembly 3. The housing assembly 1 includes a housing 11, a first fixing portion 12, and a second fixing portion 13. The first fixing portion 12 is mounted on the inner wall of the housing 11, and the second fixing portion 13 is also fixed to the inner wall of the housing 11, and the first fixing portion 12 and the second fixing portion 13 are spaced apart. The first power source assembly 2 includes a first pump 21, a first motor 22, a first water pipe 23, and a first water inlet 25. The first pump 21 is connected to the first motor 22 by driving, and the first water pipe 23 is installed at the water outlet of the first pump 21, and the two are connected. The second power source assembly 3 includes two second pumps 31, two second motors 32, a second water pipe 33, and a second water inlet 37. The second pump 31 is connected to the second motor 32 by driving, and the second pump 31 shares a water outlet and a water inlet. The second water pipe 33 is installed at the water outlet of the second pump 31, and the two are connected. The second water inlet nozzle 37 is installed at the water inlet of the two second pumps 31, and the two are connected. The first power source assembly 2 and the second power source assembly 3 are switchably installed inside the housing assembly 1.

[0034] See also Figure 1 The housing assembly 1 includes a housing 11, a first fixing portion 12 and a second fixing portion 13. The housing 11 can be made of metal. The top opening 111 of the housing 11 is the water outlet of the water pump, and the bottom of the housing 11 is used to be mounted on the mouth of the barrel of bottled water. The top of the housing 11 is flat-mouthed and extends sideways to facilitate users to receive water. The bottom of the housing 11 is cylindrical, and its shape matches the shape of the mouth of the barrel of bottled water.

[0035] The interior of the shell 11 is hollow, and any one of the first power source assembly 2 and the second power source assembly 3 can be installed as needed. In order to achieve the installation and positioning of the first power source assembly 2 and the second power source assembly 3, the inner wall of the shell 11 is provided with a first fixing portion 12 and a second fixing portion 13. The first fixing portion 12 and the second fixing portion 13 are always located on the inner wall of the shell 11. When the installed inner core is the first power source assembly 2, the first fixing portion 12 cooperates with the first power source assembly 2 to achieve the positioning of the first power source assembly 2. When the installed inner core is the second power source assembly 3, the second fixing portion 13 cooperates with the second power source assembly 3 to achieve the positioning of the second power source assembly 3.

[0036] The first fixing portion 12 and the second fixing portion 13 can be installed at different heights on the inner wall of the shell 11. Combined with the difference in the external structure of the first pump 21 and the second pump 31, the first fixing portion 12 will not interfere with the second power source assembly 3 and the second fixing portion 13 will not interfere with the first power source assembly 2.

[0037] Continue to see Figure 1 In some embodiments, the inner wall of the housing 11 is provided with a groove 110, and the groove 110 is used to accommodate the first battery 26 of the first power source assembly 2 and the second battery 38 of the second power source assembly 3 described later. The first power source assembly 2 and the second power source assembly 3 can each adopt a rechargeable structure, and their batteries are all rechargeable batteries.

[0038] See also Figure 2 The first pump 21 and the first motor 22 of the first power source assembly 2 are arranged vertically, the first battery 26 is located on the top of the first pump 21, the diameter of the first pump 21 is larger than the diameter of the first motor 22, the first pump 21 is relatively thick, and the first motor 22 is relatively thin.

[0039] In some embodiments, the first motor 22 is installed at the top of the first pump 21. The first power source assembly 2 also includes a first battery 26, which is arranged side by side with the first pump 21. The first battery 26 is flush with the bottom surface of the first pump 21, and the top of the first battery 26 is flush with the top of the first motor 22 or slightly lower than the top of the first motor 22. Part of the first battery 26 is located inside the shell 11, and part of the first battery 26 is located in the groove of the wall of the shell 11. The first battery 26 is a rechargeable battery, which realizes the multiple and repeated use of the first power source assembly 2, which is beneficial to saving user costs.

[0040] In some embodiments, the first power source assembly 2 further includes a first control panel 24, the first control panel 24 is electrically connected to the first motor 22, the first control panel 24 is mounted on the top of the first motor 22, and the first control panel 24 is located on a side of the first motor 22 away from the first pump 21. The first battery 26 can be used to power the first control panel 24, and the two are connected by wires.

[0041] Continue to see Figure 2 , the water inlet of the first pump 21 is equipped with a first water inlet nozzle 25. The first water inlet is located at the bottom of the first pump 21, and the first water outlet of the first pump 21 is located at the top of itself. Since the water pump draws water from the barreled water at the bottom, setting the first water inlet at the bottom of the first pump 21 can make it easier to arrange and install the first water inlet nozzle 25, so that the length of the first water inlet nozzle 25 can be as short as possible. In addition, in this technical solution, the water inlet of the first pump 21 does not need to form a fluid connection relationship with the bottom opening of the shell 11, and the water inlet nozzle of the first water inlet nozzle 25 of the first pump 21 directly passes through the through hole of the side wall of the shell 11. This design can improve the reliability and safety of the water pump. The material of the shell 11 does not come into contact with water, and does not need to be made of food hygiene grade materials, which can reduce the cost of the shell 11 and improve the reliability of the shell 11.

[0042] The first water inlet nozzle 25 can extend outside the housing 11, so that the first water inlet nozzle 25 can be connected to the hose. When in use, the pipeline of the hose extends to the bottom surface of the barreled water, so that the water in the barrel can be fully pumped out and the residual water in the barrel can be reduced. The inner wall of the housing 11 is also provided with a through hole 10, which is configured to allow the first water inlet nozzle 25 to pass through.

[0043] The first water pipe 23 is connected to the first water outlet of the first pump 21, and the first water outlet is located on the top side of the first pump 21. The first water pipe 23 can be a soft tube such as a rubber tube. The top of the first water pipe 23 extends from the top opening of the shell 11, or is embedded and fixed in the top opening of the shell 11.

[0044] Continue to see Figure 1 and Figure 2 , the first fixing portion 12 is a first connecting sleeve, and a first protruding portion 111 is correspondingly installed on the outer wall of the first pump 21, and the first protruding portion 111 is provided with a first connecting hole. The first fixing portion 12 and the first pump 21 are detachably fixedly connected by a first connecting member passing through the first connecting sleeve and the first connecting hole. The first connecting member is not shown in the figure, and the first connecting member is specifically a screw. The first fixing portion 12 is located at a relatively lower position of the shell 11. The first protruding portion 111 is located at the bottom or lower middle part of the outer wall of the first pump 21, and the first power source assembly 2 is inserted from the bottom opening of the shell 11. After the first power source assembly 2 is installed in place, the through holes of the first protruding portion 111 and the first connecting sleeve are aligned, and the first connecting member is passed through the through holes of the two to realize the detachable fixed connection between the first power source assembly 2 and the shell assembly 1.

[0045] In some embodiments, the number of the first fixing portions 12 is more than two, and the first fixing portions 12 are dispersedly arranged along the interior of the shell 11, for example, at intervals of 180°, so that the first power source assembly 2 can be installed more firmly.

[0046] See also Figure 3 and Figure 4 In some embodiments, the two second pumps 31 are arranged side by side and fixedly connected, the water inlets of the two second pumps 31 are connected, and the water outlets of the two second pumps 31 are connected; the second water pipe 33 is connected to the water outlets of the two second pumps 31.

[0047] The first pump 21 and the second pump 31 have different external structures, and the first motor 22 and the second motor 32 can adopt the same structure. The diameter size of the second pump 31 is substantially the same as the diameter size of the second motor 32. In this way, the total thickness of the two second pumps 31 after being fixedly connected is not much larger than the diameter size of one first pump 21, or is similar, so the first pump 21 of the first power source assembly 2 and the two second pumps 31 of the second power source assembly 3 can be installed in the housing 11.

[0048] Continue to see Figure 3 and Figure 4 In some embodiments, the second power source assembly 3 further includes a second battery 38. The two second pumps 31 are arranged side by side and fixedly connected; two concave areas are formed at the intersection of the two pumps, and the second battery 38 is installed in one of the concave areas. The second battery 38 is arranged side by side with the two second pumps 31, and a part of the second battery 38 is located in the concave area formed at the intersection of the two second pumps 31. The water outlet 311 of the second pump 31 is installed in the other concave area. The water outlet 311 of the second pump 31 is connected to the second water pipe 33. The water inlets of the two second pumps 31 are shared, so only one second water inlet 37 is needed to be connected to the water inlets of the two second pumps 31, and then the second water inlet 37 is connected to the second water pipe 33.

[0049] Continue to see Figure 3 and Figure 4 , one of the second motors 32 is located at the top of one of the second pumps 31, and the other second motor 32 is located at the top of the other second pump 31. With this arrangement, the structure of the water pump is more compact.

[0050] The second power source assembly 3 also includes a second control panel 34, which is mounted on the top of the two second batteries 38 and is located on the side of the two second batteries 38 away from the second pump 31. The two second pumps 31 are fixed together to form a whole, and the two second pumps 31 are driven by their respective second motors 32. The thickness of the second pump 31 is similar to that of the second motor 32. The entire second power source assembly 3 is a long and thin strip. The second battery 38 can be used to power the second control panel 34, and the two are connected by a wire.

[0051] In some embodiments, the second fixing portion 13 is a second connecting sleeve, which is located, for example, in the middle area of ​​the housing 11, or in the middle-upper area. The length of the second connecting sleeve may be longer than the length of the first connecting sleeve. The second power source assembly 3 also includes a pressing plate 35 and a second protrusion 36. The pressing plate 35 is located in the area where the second pump 31 and the second motor 32 are connected. The pressing plate 35 is fixedly connected to both second pumps 31, and the edge of the pressing plate 35 is fixedly mounted with a second protrusion 36, and the second protrusion 36 is provided with a second connecting hole. The second fixing portion 13 and the second pump 31 are detachably fixedly connected by passing the second connecting sleeve and the second connecting hole through the second connecting member. The second connecting member is not shown in the figure, and the second connecting member is specifically a screw. The second power source assembly 3 is inserted into the housing 11 from the bottom of the housing 11. After the second power source assembly 3 is inserted into place, the second connecting sleeve and the second connecting hole of the second protrusion 36 are aligned, and the second connecting member passes through the second connecting sleeve and the second connecting hole of the second protrusion 36 to detachably fix the housing assembly 1 and the second power source assembly 3.

[0052] In some embodiments, the number of the second fixing portions 13 is more than two, and the second fixing portions 13 are dispersedly arranged along the interior of the housing 11 , and the second fixing portions 13 and the first fixing portions 12 are staggered.

[0053] See also Figure 1 , Figure 3 and Figure 4 In some embodiments, the water inlet of the second pump 31 is equipped with a second water inlet nozzle 37; the inner wall of the housing 11 is also provided with a through hole 10, which is configured to allow the second water inlet nozzle 37 to pass through. In this arrangement, the second water inlet nozzle 37 is directly used to contact water, and the housing 11 does not need to contact water, which can reduce the material requirements for the housing 11 and save costs.

[0054] The above technical solution increases the selectivity of the water output efficiency of the water pump and can meet the requirements of high-efficiency water output. Since the same shell assembly is used, it maintains a small and exquisite appearance while also taking into account a large water flow rate, saving time and significantly improving the user experience.
