Description

Technical Field

[0001] This utility model relates to the field of water pump technology, specifically a dual-battery water pump. Background Technology

[0002] A water pump is a device that uses mechanical energy to move water from one place to another, either by pumping liquid from a low place to a high place or by propelling liquid in a pipe. It is commonly used in industrial production, household water supply, and various other fields. However, water pumps require an external power source to operate, and cannot be used where there is no power supply. This led to the development of battery-powered water pumps. But because battery-powered water pumps have a small battery capacity, they cannot operate for extended periods, thus failing to meet the requirements for long-term use. Utility Model Content

[0003] The purpose of this invention is to provide a dual-battery water pump to solve the problem mentioned in the background art that the battery capacity is too small to meet the requirements of long-term use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a dual-battery water pump, comprising a middle frame, one end of which is circular, and a top cover is fixedly mounted on the circular outer surface of the middle frame. A circuit control display board is fixedly mounted between the top cover and the middle frame, and a charging port is fixedly mounted on the outer surface of the middle frame. A handle is fixedly mounted on the outer surface of the top cover. A front shell is fixedly mounted on the outer surface of one end of the middle frame, and a rear shell is fixedly mounted on the outer surface of the middle frame away from the front shell. The rear shell and the front shell are respectively engaged with the middle frame. The water pump body is fixedly mounted inside the middle frame. A power monitoring and control module is fixedly mounted on the outer surface of the middle frame and is connected to the circuit control display board. A plugging and fixing mechanism is provided between the front shell and the rear shell, which facilitates the insertion, removal, and replacement of the battery to improve the service life of the water pump.

[0005] Preferably, the insertion and fixing mechanism includes: a sliding mounting plate, two sliding mounting plates are respectively fixedly installed on the outer surfaces of the rear housing and the front housing, two battery insertion bases are engaged on the outer surface of the sliding mounting plate, and the battery insertion bases are fixed to the sliding mounting plate by screws, two battery blocks are engaged on the outer surface of the battery insertion bases, a battery replacement indicator plate is fixedly installed on the outer surface of the top cover, and a reflector is fixedly installed on the outer surface of the battery replacement indicator plate, the outer surface of the reflector penetrates the outer surface of the top cover, and the reflector protruding from the outer surface of the top cover has an inverted conical design.

[0006] By adopting the above technical solution, the sliding mounting plate can be fixed to the outer surface of the front and rear housings. When the battery socket is damaged, it can be removed from the sliding mounting plate for replacement. When using battery packs with different sockets, the battery socket can also be replaced. At the same time, a fully charged battery pack can be replaced to extend the water pump's operating time. When the battery on one side is depleted, the corresponding battery replacement indicator will start flashing. The inverted cone design of the reflector allows the light emitted by the battery replacement indicator to be reflected to both sides of the water pump, quickly reminding the user to replace the depleted battery. This greatly improves the flexibility and versatility of battery use and the convenience of battery replacement.

[0007] Preferably, a flip-top protective cover is rotatably mounted on the outer surfaces of the front and rear outer shells, and a fastening hook is fixedly mounted on the end of the flip-top protective cover away from the handle, and the fastening hook engages with the front and rear outer shells respectively, and the inner surface of the flip-top protective cover is in contact with the outer surface of the battery block.

[0008] By adopting the above technical solution, the battery block inserted into the water pump can be protected by the snap-fit ​​hook, reducing the chance of damaging the battery block, and the flip cover can be fixed by the snap-fit ​​hook.

[0009] Preferably, the pump body is located on the side of the middle frame near the rear outer shell, and the outer surface of the middle frame is penetrated by the outer surface of the fastening copper nozzle, and the outer surface of the fastening copper nozzle is in contact with the outer surface of the middle frame. The fastening copper nozzle and the pump body are connected by threads.

[0010] Using the above technical solution, the snap-fit ​​copper nozzle can be unscrewed from the water pump body for replacement, so that pipes of different sizes can be inserted into the snap-fit ​​copper nozzle.

[0011] Preferably, the end of the buckling copper nozzle located outside the middle frame is provided with a block-shaped protrusion, and the two sides of the middle frame are designed in a circular shape, and the circular design of the middle frame is concentric with the buckling copper nozzle. The outer surface of the middle frame near the buckling copper nozzle is provided with engraved characters.

[0012] By adopting the above technical solution, the blocky protrusions of the copper nozzle can reduce the chance of the pipe falling off and coming detached, while the circular design of the middle frame can make it easier to insert the pipe, and the input and output pipes can be accurately identified by the engraved characters.

[0013] Preferably, a ventilation mechanism is provided between the middle frame and the front outer shell, which facilitates cooling of the water pump body and improves the operational stability of the water pump body.

[0014] By adopting the above technical solution, the temperature of the water pump body can be reduced and the operational stability of the water pump body can be improved.

[0015] Preferably, the ventilation mechanism includes: a sliding slot, the sliding slot being fixedly disposed on the side surface of the middle frame, a ventilation fan being inserted and installed inside the sliding slot, and the ventilation fan being disposed on both sides of the middle frame, ventilation holes being provided through the outer surfaces of both sides of the middle frame and the front shell, and the ventilation holes and the ventilation fan being concentrically designed, and a flexible buckle being provided on the outer surface of the sliding slot, and the flexible buckle engaging with the ventilation fan.

[0016] The above technical solution allows for easy fixing and replacement of the ventilation fan. The ventilation fan can create convection, allowing air to enter through the ventilation holes and exit to remove the heat generated by the water pump.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This dual-battery water pump: 1. The power monitoring and control module monitors the water pump's battery. When the power of one battery is depleted, the module switches to a different battery. The battery replacement indicator will then flash and reflect light through a reflector, allowing the light to reach both ends of the water pump. This makes it easy for the user to notice that the battery needs to be replaced. Simply open the flip cover, remove the battery from the battery socket, and replace it with a fully charged battery to extend the water pump's lifespan. Alternating between two battery modules allows for uninterrupted battery replacement. Alternatively, the user can use a battery socket that matches the interface of their battery module, improving the convenience and flexibility of battery replacement and usage, and extending the water pump's operating time. 2. By rotating the locking copper nozzle, the locking copper nozzle can be unscrewed from the water pump body. Then, take the corresponding size locking copper nozzle according to the pipe being used and screw it back onto the water pump body. This is convenient for use with pipes of different sizes. At the same time, the round design on both sides of the middle frame makes it easier to insert the pipe into the locking copper nozzle and protects the locking copper nozzle from impact damage. In addition, the engraved lettering ensures that the pipe is not connected backwards when it is inserted. 3. As the water pump starts, it will generate heat. At this time, the start of the ventilation fan will create convection, allowing air to pass through the ventilation holes and the interior of the middle frame and front shell to remove the heat generated by the water pump during operation, thus accelerating the dissipation of the water pump's temperature. In case the ventilation fan is damaged, the flexible clips can be engaged to pull the ventilation fan out of the sliding slot for replacement without the need for screws. At the same time, the large amount of airflow can remove the heat from the water pump, allowing the water pump to operate stably. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-6 This utility model provides a technical solution: a dual-battery water pump, including a middle frame 1, one end of which is circular, and a top cover 5 is fixedly installed on the circular outer surface of the middle frame 1. A circuit control display board 18 is fixedly installed between the top cover 5 and the middle frame 1, and a charging port is fixedly installed on the outer surface of the middle frame 1. A handle 4 is fixedly installed on the outer surface of the top cover 5. A front shell 2 is fixedly installed on the outer surface of one end of the middle frame 1, and a rear shell 3 is fixedly installed on the outer surface of the middle frame 1 away from the front shell 2. The rear shell 3 and the front shell 2 are respectively engaged with the middle frame 1. The water pump body 8 is fixedly installed inside the middle frame 1, and a power monitoring and control module 19 is fixedly installed on the outer surface of the middle frame 1. The power monitoring and control module 19 is connected to the circuit control display board 18. A plugging and fixing mechanism is provided between the front shell 2 and the rear shell 3. The plugging and fixing mechanism facilitates the insertion, removal and replacement of the battery to improve the service life of the water pump.

[0022] The water pump can be easily lifted and moved by the handle 4 for convenient access. The circuit control display board 18 on the outer surface of the top cover 5 clearly and accurately shows the remaining power of the battery. At the same time, the power monitoring and control module 19 can monitor the power of the two batteries in the water pump. When the power of one battery is used up, the power monitoring and control module 19 can switch to another spare battery. This allows for automatic switching after the battery is used up, extending the usage time. The water pump can also be used for a long time by replacing the battery.

[0023] The insertion and fixing mechanism includes: a sliding mounting plate 10, two sliding mounting plates 10 are respectively fixedly installed on the outer surfaces of the rear housing 3 and the front housing 2, two battery insertion bases 11 are engaged and installed on the outer surface of the sliding mounting plate 10, and the battery insertion bases 11 and the sliding mounting plate 10 are fixed with screws, two battery blocks are engaged and installed on the outer surface of the battery insertion bases 11, a battery replacement indicator plate 17 is fixedly installed on the outer surface of the top cover 5, and a reflector 20 is fixedly installed on the outer surface of the battery replacement indicator plate. The outer surface of the reflector 20 penetrates the outer surface of the top cover 5, and the reflector 20 protruding from the outer surface of the top cover 5 is designed in an inverted cone shape.

[0024] The battery pack can be installed and plugged in via the battery socket 11. Two battery packs can extend the water pump's operating time. The operating time of the water pump can be increased by replacing the battery packs. When using battery packs with different interfaces, the battery socket 11 can be removed from the sliding mounting plate 10 and the corresponding battery socket 11 can be replaced. This allows the use of battery packs with different interfaces, improving the flexibility of the water pump when using batteries. When the power of a battery is depleted, the corresponding battery replacement indicator 17 will start to flash. The inverted cone design of the reflector 20 allows the light to be reflected to both ends of the water pump to remind the user to replace the battery. This improves the flexibility of battery use while ensuring the timeliness and convenience of battery replacement.

[0025] A flip cover 6 is rotatably mounted on the outer surfaces of the front housing 2 and the rear housing 3. A latching hook 7 is fixedly mounted on the end of the flip cover 6 away from the handle 4. The latching hook 7 is engaged with the front housing 2 and the rear housing 3 respectively. The inner surface of the flip cover 6 is in contact with the outer surface of the battery block.

[0026] By engaging the latch 7 with the front housing 2 and the rear housing 3, the flip cover 6 can be fixed to the outer surfaces of the front housing 2 and the rear housing 3. Closing the flip cover 6 can protect the battery pack and reduce the chance of the battery pack being damaged by impact.

[0027] The pump body 8 is located on the side of the middle frame 1 near the rear outer shell 3, and the outer surface of the middle frame 1 is penetrated by the outer surface of the fastening copper nozzle 9, and the outer surface of the fastening copper nozzle 9 is in contact with the outer surface of the middle frame 1. The fastening copper nozzle 9 and the pump body 8 are connected by threads.

[0028] The snap-fit ​​copper nozzle 9 can be easily unscrewed from the water pump body 8 and replaced to accommodate different pipes inserted into the outer surface of the snap-fit ​​copper nozzle 9.

[0029] The snap-fit ​​copper nozzle 9 has a block-shaped protrusion at one end outside the middle frame 1, and the two sides of the middle frame 1 are circular. The circular design of the middle frame 1 and the snap-fit ​​copper nozzle 9 are concentric. The outer surface of the middle frame 1 near the snap-fit ​​copper nozzle 9 is engraved with the characters 12.

[0030] The block-shaped protrusion of the snap-fit ​​copper nozzle 9 reduces the risk of the pipe falling off. The circular design of the middle frame 1 allows the pipe to be inserted into the snap-fit ​​copper nozzle 9 for easy pipe installation and protects the snap-fit ​​copper nozzle 9 from impact and breakage. The engraved lettering 12 distinguishes the inlet and outlet of the water pump body 8.

[0031] A ventilation mechanism is provided between the middle frame 1 and the front outer shell 2. The ventilation mechanism facilitates the cooling of the water pump body 8 and improves the operational stability of the water pump body 8.

[0032] The convection created by the rotation of the ventilation fan 14 allows air to enter the interior of the middle frame 1 and the front outer casing 2 through the ventilation holes 15, accelerating the removal of the temperature from the water pump body 8 and enabling the water pump to operate stably.

[0033] The ventilation mechanism includes: a sliding slot 13, which is fixedly installed on the side surface of the middle frame 1. A ventilation fan 14 is installed inside the sliding slot 13 and is located on both sides of the middle frame 1. Ventilation holes 15 are provided through the outer surfaces of the middle frame 1 and the front shell 2. The ventilation holes 15 and the ventilation fan 14 are concentrically designed.

[0034] When the ventilation fan 14 is damaged, the flexible clip 16 can be lifted to disengage the flexible clip 16 from the ventilation fan 14, allowing the ventilation fan 14 to be removed from the sliding slot 13 for replacement. After that, the new ventilation fan 14 can be inserted into the sliding slot 13. Once the ventilation fan 14 is fully inserted into the sliding slot 13, the flexible clip 16 will spring back and engage with the ventilation fan 14, making it easy to install and replace the ventilation fan 14 without the need for screws.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
