Description

Technical Field

[0001] This application relates to the field of water pump structure technology, and in particular to a battery-integrated water pump. Background Technology

[0002] A water pump is a machine that transports or pressurizes liquids. It transfers the mechanical energy of a prime mover or other external energy to the liquid, increasing the liquid's energy. It is mainly used to transport liquids including water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals. It can also transport liquid-gas mixtures and liquids containing suspended solids.

[0003] Most existing water pumps are powered by either an external power source or a built-in battery. However, the external power source method is limited by the power cord, which makes the water pump less portable and less adaptable to different scenarios. Therefore, most water pumps on the market now use a built-in battery to power them.

[0004] Chinese patent discloses a fixing structure for a lithium battery submersible pump (publication number: CN214331003U), including a housing and a base, which are connected by screws. A motor is located on one side of the housing, and an impeller is located at a corresponding position in the base. A battery compartment is located on the other side of the housing. Several axial limiting ribs are distributed circumferentially on the inner wall of the battery compartment. Two support plates with a certain interval are located on the top. Two opposing battery racks are located inside the battery compartment, and a certain number of batteries are installed between the racks. Support blocks are located at the upper ends of the battery racks. The base, located below the battery compartment, has an opening, within which a battery compartment cover is installed. The upper outer edge of the battery compartment cover abuts against the limiting ribs. A clamping ring is fitted onto the outer wall of the battery compartment cover, and a sealing ring is provided between the top of the clamping ring and the battery compartment cover. Several screw holes are distributed circumferentially on the bottom, and the clamping ring is connected to the base by screws.

[0005] The aforementioned water pump places the battery compartment opening below the battery compartment and the battery compartment cover on the opening; when the submersible pump is in use, the weight of the battery is concentrated on the battery compartment cover at the opening, which poses a risk of deformation and liquid seepage into the battery compartment. Summary of the Invention

[0006] To address the problems existing in the prior art, this application provides a battery-embedded water pump that can prevent liquid from seeping into the battery compartment, thereby eliminating the need for additional waterproofing design for the battery pack and its interfaces, making it safer and less costly.

[0007] The technical solution adopted in this application is as follows:

[0008] A battery-powered water pump includes a pump body.

[0009] The pump body is provided with horizontally distributed and adjacent battery compartments and mounting cavities;

[0010] The pump body is also provided with an inlet and an outlet;

[0011] The upper part of the mounting cavity is equipped with a control panel;

[0012] The battery compartment is detachably connected to a battery pack, and the upper part of the battery compartment is detachably connected to a battery compartment cover.

[0013] The battery compartment cover is equipped with a handle;

[0014] A motor is installed inside the mounting cavity;

[0015] The control panel is electrically connected to the battery pack and the motor, respectively.

[0016] According to an embodiment of the present invention, the battery compartment is provided with a guide groove and contact terminals;

[0017] The battery pack is equipped with a guide block and an output slot;

[0018] The guide block and guide groove are fitted together and slidably connected;

[0019] The contact terminal is electrically connected to the output slot.

[0020] The battery pack achieves sliding connection and detachable installation within the battery compartment through the cooperation of guide blocks and guide grooves; at the same time, the battery pack also achieves electrical connection between itself and the pump body through the electrical connection between the contact terminals and the output groove, thereby enabling power supply to the pump body.

[0021] According to an embodiment of the present invention, the battery compartment cover is fastened to the battery compartment;

[0022] A sealing ring is also fitted on the battery compartment cover, which is used to improve the sealing between the battery compartment cover and the battery compartment.

[0023] The sealing ring is used to further improve the sealing between the battery compartment and the battery compartment cover. When the water pump needs to be submerged, the water pump can also prevent liquid from seeping into the battery compartment through the sealing ring.

[0024] According to an embodiment of the present invention, the control panel includes a wireless module, and the control panel is wirelessly connected to the remote control via the wireless module.

[0025] The aforementioned wireless module enables remote control of the water pump's start / stop or other functions.

[0026] According to an embodiment of the present invention, a connector is provided between the remote control and the handle, and the remote control is detachably connected to the handle through the connector.

[0027] When the remote control is needed, it can be detached from the pump body for use; when the remote control is not needed, it can be stored and attached to the pump body to prevent it from being lost.

[0028] According to an embodiment of the present invention, the connector is a magnetic adsorption component;

[0029] The remote control is attached to the handle by a magnetic attachment.

[0030] According to an embodiment of the present invention, the connector includes a limiting groove;

[0031] The limiting groove is provided on the side of the handle, and the remote control is slidably connected to and limited in the limiting groove.

[0032] According to an embodiment of the present invention, the water pump further includes a safety switch;

[0033] The safety switch is located at the connection between the battery compartment cover and the battery compartment, and is used to control the on / off state of the circuit between the battery pack and the control panel.

[0034] The safety switch is connected to the control panel signal, or the safety switch is connected in series in the circuit between the control panel and the battery pack.

[0035] The safety switch ensures that the water pump only operates when the battery compartment cover is fully connected to the battery compartment; it further prevents the water pump from starting to operate before the battery compartment and battery compartment cover are fully closed, which could lead to liquid leakage inside the battery compartment and cause the water pump to burn out due to a short circuit.

[0036] According to an embodiment of the present invention, the safety switch is a magnetic induction element;

[0037] The magnetic sensing element is a Hall switch;

[0038] The Hall switch includes a Hall sensor and a sensing magnet;

[0039] The Hall sensor is mounted on the battery compartment, and the sensing magnet is mounted on the battery compartment cover.

[0040] When the battery compartment is connected to the battery compartment cover, the Hall sensor and the sensing magnet are projected at the same position in the horizontal plane.

[0041] According to an embodiment of the present invention, the battery pack is provided with a plurality of batteries, wherein the batteries are lithium batteries.

[0042] Lithium batteries have advantages such as high energy density, long service life, high power handling capacity, light weight, and environmental friendliness.

[0043] According to an embodiment of the present invention, the pump body further includes an impeller and a diffuser chamber;

[0044] The water inlet is located at the bottom of the pump body;

[0045] The diffusion chamber is located inside the pump body and connects the inlet and outlet.

[0046] The motor is electrically connected to the control panel;

[0047] The impeller is connected to the output shaft of the motor.

[0048] According to an embodiment of the present invention, a floating structure is also connected to the pump body.

[0049] According to an embodiment of the present invention, the floating structure includes a float and a hinge; the hinge is used to hinge the float to the side of the pump body.

[0050] The floating structure allows the water pump to float on the liquid surface, and the floating component is rotatably hinged to the pump body, making it easy to store and carry when not in use.

[0051] According to an embodiment of the present invention, the floating component includes a float and a cover of one-piece structure; or, the floating component includes a float and a cover of two separate structures, wherein the float is connected inside the cover.

[0052] One side of the cover is connected to the hinge, and the other side of the cover is fastened to the pump body.

[0053] According to an embodiment of the present invention, the hinge includes a fixing member disposed on the side of the pump body and a movable member connected to the cover.

[0054] The fixed component is provided with a limiting grid plate; the movable component includes a movable curved surface and a limiting plane;

[0055] The limiting plane and the limiting grid plate cooperate with each other to limit the rotation angle of the cover;

[0056] The rotation angle is 0 to 135°.

[0057] The limiting grid plate and the limiting plane interact to limit the rotation angle of the float, thereby ensuring that the contact area between the float and the liquid surface is maximized, thus ensuring that the maximum buoyancy is provided to the water pump.

[0058] The beneficial effects of this application are as follows:

[0059] The battery compartment cover of the pump body is located at the top of the battery compartment. When the water pump is in use, the connection between the battery compartment and the battery compartment cover is located at the top of the pump body, and the battery pack does not exert force on the battery compartment cover, thereby preventing liquid from seeping into the battery compartment. This allows the water pump to use a universal battery pack and battery pack connector without the need for additional waterproofing design.

[0060] The battery compartment cover is equipped with a handle, which makes it easy for users to remove and install the battery compartment cover, and also makes it easy for users to lift and move the water pump by using the handle.

[0061] On the other hand, the control panel and battery compartment cover are respectively located at the top of the mounting cavity and the top of the battery compartment, which can prevent the handle from interfering with the position of the control panel, making it more convenient to use. In addition, the cable length of the electrical connection between the control panel, the battery compartment, and the motor can also be shortened, thus making the overall circuit structure more compact.

[0062] The aforementioned floating structure allows the water pump to float on the liquid surface, thereby further preventing liquid leakage into the battery compartment and preventing potential blockage of the water inlet due to sinking to the bottom, thus improving the efficiency of liquid pumping.

[0079] Example 1

[0080] Please see Figures 1-6 This embodiment provides a battery-powered water pump.

[0081] The water pump includes a pump body 1, which contains a battery compartment 2 and a mounting cavity 15. The battery compartment 2 and the mounting cavity 15 are adjacent to each other but not connected. A motor 12 is installed in the mounting cavity 15, and an impeller 13 is connected to the output shaft of the motor 12. The bottom of the pump body 1 has an inlet 10, and the top surface of the pump body 1 has an outlet 11. The pump body 1 also has a channel connecting the inlet 10 and the outlet 11. The channel includes a pressurization zone, a diffusion chamber 14, and a conveying zone connected in sequence. The pressurization zone is connected to the inlet 10, the diffusion chamber 14 is located between the pressurization zone and the conveying zone, and the conveying zone is connected to the outlet 11. The impeller 13 is located in the pressurization zone. After the liquid enters the pressurization zone through the inlet 10, it is pressurized by the rotation of the impeller 13 and conveyed to the diffusion zone for pressure release. The released pressure is then conveyed through the conveying zone to the outlet 11, and finally discharged from the outlet 11.

[0082] The battery compartment 2 is detachably connected to a battery pack 3. Specifically, the battery pack 3 contains eight lithium batteries 3c connected in series. Two guide grooves 2a are vertically arranged along the wall of the battery compartment 2. Each guide groove 2a has an opening, and the openings of the two guide grooves 2a face each other and are parallel to each other. Two guide blocks 3a are also provided at corresponding positions on the side of the battery pack 3, cooperating with the guide grooves 2a. The guide blocks 3a cooperate with the guide grooves 2a to form a limiting connection. Through this limiting connection, the battery pack 3 can slide up and down within the battery compartment 2. When the battery pack 3 slides to the bottom, it is fully connected to the battery compartment 2. When the battery pack 3 slides upward to the guide blocks 3a… When the battery pack 3 slides out of the guide groove 2a, it is completely disconnected from the battery compartment 2. Furthermore, a contact terminal 2b is provided between the two guide grooves 2a. The contact terminal 2b is made of conductive metal. Correspondingly, an output groove 3b is also provided between the two guide blocks 3a. The output groove 3b is provided with a contact piece. The contact piece is made of conductive metal and is electrically connected to the lithium battery 3c. The lithium battery 3c outputs power to other objects waiting to be powered through the contact piece. When the battery pack 3 slides to the bottom and the battery pack 3 is fully connected to the battery compartment 2, the contact terminal 2b is inserted into the output groove 3b and abuts against the contact piece in the output groove 3b. At this time, the control panel 5 is electrically connected to the battery pack 3 through the battery compartment 2.

[0083] The battery compartment 2 has an opening at its top for installing or removing the battery pack 3 into the battery compartment 2. Preferably, a battery compartment cover 4 is connected to the opening. The battery compartment cover 4 is a cylindrical structure, and two fasteners 16 are symmetrically and evenly spaced at the bottom of the outer circumferential surface of the battery compartment cover 4. Two fasteners 16 are also provided at corresponding positions on the inner circumferential surface of the opening of the battery compartment 2. The fasteners 16 on the battery compartment 2 and the fasteners 16 on the battery compartment cover 4 cooperate with each other and are positioned accordingly. The battery compartment 2 and the battery compartment cover 4 are fastened together by the fasteners 16. Furthermore, a sealing ring 4a is also provided circumferentially on the outer circumferential surface of the battery compartment cover 4. The sealing ring 4a is used to enhance the sealing performance when the battery compartment cover 4 is connected to the battery compartment 2 and prevent external liquid from entering the battery compartment 2.

[0084] Furthermore, the pump body 1 is provided with a control panel 5, which is located on the top surface of the mounting cavity 15. The control panel 5 is electrically connected to the motor 12 and is also electrically connected to the contact terminal 2b of the battery compartment 2. The battery pack 3 supplies power to the control panel 5 and the motor 12 through the battery compartment 2. The control panel 5 controls the start and stop of the motor 12, thereby controlling the start and stop of the water pump.

[0085] Example 2

[0086] Please see Figures 1-6 This embodiment provides another embodiment based on the above embodiments.

[0087] The pump body 1 is also provided with a mating hole 21, which is located on the side of the pump body 1 away from the water outlet and extends through the pump body 1 into the battery compartment 2. A limiting hole 22 is provided on the outer surface of the battery compartment cover 4. The diameter of the limiting hole 22 is set to be the same as the diameter of the mating hole 21, and both the mating hole 21 and the limiting hole 22 are provided with internal threads. When the battery compartment cover 4 and the battery compartment 2 are snapped together by the snap fastener 16, the positions of the mating hole 21 and the limiting hole 22 are exactly matched. The water pump further fixes the battery compartment 2 and the battery compartment cover 4 by installing screws into the mating hole 21 and threading the screws through the mating hole 21 into the limiting hole 22, thereby preventing them from loosening or deviating in position, and further preventing liquid leakage from the battery compartment 2.

[0088] Example 3

[0089] Please see Figures 1-10 This embodiment provides another embodiment based on the above embodiments.

[0090] The battery-built water pump is also equipped with a safety switch. The safety switch is located at the connection between the battery compartment 2 and the battery compartment cover 4, and is electrically connected to the battery compartment 2. The safety switch is used to switch the circuit between the battery compartment 2 and the control panel 5.

[0091] Preferably, the safety switch is a magnetic induction element, specifically a Hall switch. The Hall switch includes a Hall sensor 19 and a sensing magnet 20. The Hall sensor 19 is disposed in the wall of the battery compartment 2, near the connection between the battery compartment 2 and the battery compartment cover 4, and is electrically connected to the control panel 5. The Hall sensor 19, the battery compartment 2, and the control panel 5 are connected in series. The Hall sensor 19 is used to switch the circuit connection between the battery compartment 2 and the control panel 5. The sensing magnet 20 is installed in the battery compartment cover 4, specifically near the battery compartment 2 and the battery compartment cover 4. At the connection point; when the battery compartment 2 and the battery compartment cover 4 are connected by the snap fastener 16, the Hall sensor 19 and the induction magnet 20 are exactly opposite each other. The Hall sensor 19 generates a potential difference under the action of the induction magnet 20. At this time, a circuit is formed between the battery compartment 2 and the control panel 5, and the battery pack 3 supplies power to the water pump through the battery compartment 2; when the battery compartment 2 and the battery compartment cover 4 are not fully connected, the positions of the Hall sensor 19 and the induction magnet 20 are not matched. At this time, the Hall sensor 19 does not generate a potential difference, and an open circuit is formed between the battery compartment 2 and the control panel 5. At this time, the battery pack 3 does not supply power to the battery compartment 2.

[0092] Alternatively, the Hall switch can also be connected to the control panel 5. When the battery compartment 2 and the battery compartment cover 4 are connected by the snap fastener 16, the Hall sensor 19 and the sensing magnet 20 are exactly in opposite positions. At this time, the Hall switch outputs a connection signal to the control panel 5. After receiving the connection signal, the control panel 5 controls the electrical connection between the battery pack 3 and the control panel 5 to form a circuit, thereby enabling the battery pack 3 to supply power to the control panel 5 and the battery. When the battery compartment 2 and the battery compartment cover 4 are not fully connected, the Hall switch outputs a disconnect signal to the control panel 5. After receiving the disconnect signal, the control panel 5 disconnects or keeps the electrical connection between the battery pack 3 and the control panel 5 disconnected.

[0093] Preferably, the safety switch can also be a pressure switch; when the safety switch is a pressure switch, the battery compartment cover 4 is provided with a pressing element, and the battery compartment 2 is provided with a contact element. When the battery compartment cover 4 and the battery compartment 2 are connected, the pressing element presses on the contact element; at this time, the pressure switch transmits a signal to the control panel 5, and the control panel 5 controls the circuit between the battery pack 3 and the control panel 5 to form a circuit, or the battery pack 3, the pressure switch, and the control panel 5 are connected in series. When the pressure switch forms a circuit, a direct circuit is formed between the battery pack 3 and the control panel 5.

[0094] The structure of the safety switch ensures that the water pump is powered on only when the battery compartment 2 and the battery compartment cover 4 are fully connected, preventing liquid leakage into the battery compartment 2 and causing the water pump to short-circuit and burn out.

[0095] Example 4

[0096] Please see Figures 1-6 This embodiment provides another embodiment based on the above embodiments.

[0097] This embodiment provides a floating structure, which is applied to the battery-built water pump described in any of the above embodiments.

[0098] Specifically, the floating structure includes a float and a hinge; the pump body 1 is provided with two floats, which are symmetrically arranged on opposite sides of the pump body 1. Each float includes a float 6 and a housing 7. The float 6 can be a hollow plastic block or made of a buoyant material. In this embodiment, the material and structure of the float 6 are not limited; any buoyant material in the prior art can be used to manufacture the float 6 in this application. The float 6 is fixed to the housing 7 by a threaded connection; the hinge is used to hinge the structure. Preferably, the hinge member on the side of the cover 7 and the pump body 1 includes a fixed member 18 and a movable member 17. The fixed member 18 is fixedly connected to the side of the pump body 1, and the movable member 17 is installed on one side of the cover 7. This side of the cover 7 is rotatably connected to the pump body 1 through the hinge between the movable member 17 and the fixed member 18, and the cover 7 can rotate on the pump body 1 through the hinge. A hook is provided on the opposite side of the cover 7, and a hook groove is provided at the corresponding position of the pump body 1. The hook and the hook groove cooperate with each other to form a fastening connection. When the cover 7 is closed, the cover 7 and the pump body 1 are fixed together by the hook and the groove, and the float 6 is located between the cover 7 and the pump body 1. When the cover 7 is opened, the hook and the groove separate, and the cover 7 is rotated by hinge to be perpendicular to the side of the pump body 1. At this time, the float 6 is located at the bottom of the cover 7. In this state, when the water pump of this application is placed in the liquid, the float 6 will float on the liquid surface, thereby making the pump body 1 float on the liquid surface. This allows the opening of the battery compartment 2 to be set higher than the liquid surface, preventing liquid from entering the battery compartment 2, while ensuring that the water inlet 10 at the bottom of the pump body 1 can be submerged in the liquid, so as not to affect the pumping function of the water pump.

[0099] Preferably, the angle at which the cover 7 rotates on the pump body 1 via the hinge is 0 to 135°.

[0100] Furthermore, an expansion block 6a is provided on the side of the float 6 near the hinge member. The expansion block 6a is configured to protrude from the plane of the cover 7. The expansion block 6a is used to increase the volume of the float 6, thereby increasing the drainage capacity of the float 6 and increasing the buoyancy that the water pump can obtain. Furthermore, a groove for accommodating the expansion block 6a is provided on the side of the pump body 1. The groove is located on the side of the pump body 1 near the outlet 11. The location of the groove allows for maximizing the volume of the groove and the expansion block 6a without affecting the installation space of the impeller 13.

[0101] Furthermore, both the movable component 17 and the fixed component 18 are composed of three hinged sections arranged side by side. The hinged structure can extend and increase the contact area between the floating component and the pump body 1, thereby improving the connection stability of the floating component and preventing it from shifting position.

[0102] Example 5

[0103] Please see Figures 1-6 This embodiment provides another embodiment based on the above embodiments.

[0104] The control panel 5 also includes a wireless module, and the water pump also includes a remote control 9. The remote control 9 and the control panel 5 are wirelessly connected through the wireless module. The remote control 9 remotely controls the control panel 5 to start and stop the motor 12, thereby controlling the water pump to start and stop. In this embodiment, the wireless connection method is not limited. Any existing method that can wirelessly connect and control can be used in this embodiment.

[0105] The top surface of the battery compartment cover 4 is also provided with a handle 8, which is made of magnetic metal; preferably, the handle 8 is made of heat-treated tempered martensitic stainless steel, or is made of metal iron with an outer layer of anti-rust paint, so as to ensure good rust resistance while having magnetic force; the handle 8 includes vertical plates on both sides and a recessed cavity between the vertical plates; a permanent magnet is installed inside the remote control 9, preferably a magnet 9a, and the remote control 9 can be attracted to the recessed cavity of the handle 8 by the magnet 9a.

[0106] Preferably, the handle 8 is made of plastic or other non-magnetic material, but the handle 8 is provided with a ferromagnet, and the remote control 9 is attracted to the ferromagnet of the handle 8 by a magnet 9a.

[0107] Preferably, the handle 8 is made of plastic or other non-magnetic material, but the handle 8 is provided with a magnet 9a, the remote control 9 is provided with a ferromagnetic body or the remote control 9 includes a shell made of magnetic metal, and the remote control 9 is attracted to the magnet 9a of the handle 8.

[0108] When the water pump needs to be remotely controlled wirelessly, remove the remote control 9 from the handle 8; when the hand pump needs to be stored, magnetically attach the remote control 9 to the chamber of the handle 8 to prevent the remote control 9 from being lost.

[0109] Example 6

[0110] Please see Figures 7-9This embodiment provides another embodiment based on the above embodiments.

[0111] The handle 8 includes vertical plates on both sides and a recessed chamber between the vertical plates. A limiting groove 8a is formed between the vertical plate near the control panel 5 and the chamber. The limiting groove 8a accommodates the remote control 9 and allows the remote control 9 to slide within the limiting groove 8a. Preferably, the vertical plate forming the limiting groove 8a also has a mating groove 8b, and the side of the remote control 9 has a mating block 9b for mating with the mating groove 8b. Both ends of the mating block 9b have inclined surfaces. When the remote control 9 slides within the limiting groove 8a, the inclined surfaces allow the mating block 9b to engage with the mating groove 8b, thus fixing the remote control 9 to the limiting groove 8a. The inclined surfaces facilitate the engagement and disengagement of the mating block 9b from the mating groove 8b.

[0112] When the water pump needs to be remotely controlled wirelessly, the remote control 9 can be slid out from the limiting groove 8a of the handle 8; when the hand pump needs to be stored, the remote control 9 can be fixed in the limiting groove 8a by the cooperation between the mating block 9b and the mating groove 8b, so as to prevent the remote control 9 from being lost.

[0113] Example 7

[0114] Please see Figures 7-9 This embodiment provides another embodiment based on the above embodiments.

[0115] The fixing member 18 is provided with a limiting grid plate 18a, which includes a contact surface parallel to the side of the pump body 1 and for contacting the movable member 17. The movable member 17 includes a movable curved surface 17a and a limiting plane 17b, which are arranged adjacent to each other. When the floating member and the pump body 1 are closed, the contact surfaces of the movable curved surface 17a and the limiting grid plate 18a are in contact with each other, and the limiting plane 17b is perpendicular to the side of the pump body 1. When the floating member is unfolded and rotated through the hinge, the contact surfaces of the movable curved surface 17a and the limiting grid plate 18a are in contact with each other and rotate. As the rotation angle increases, the limiting plane 17b and the pump body 1 tend to be parallel. When the rotation angle is 90°, the movable curved surface 17a... 7a disengages from the contact surface between itself and the limiting grid plate 18a. The limiting plane 17b and the contact surface of the limiting grid plate 18a abut against each other. With the cooperation between the limiting plane 17b and the limiting grid plate 18a, the float reaches the limit of its rotation angle. At this time, the plane where the float 6 is located is perpendicular to the side of the pump body 1. When the water pump is used in this state, the bottom surface of the float 6 is completely in contact with the liquid surface, thereby ensuring that the float 6 floats on the liquid surface with its maximum area, thus giving the water pump maximum buoyancy.

[0116] Preferably, considering the wear between the fixed member 18 and the movable member 17, the angle range of the floating member rotating on the pump body 1 via the hinge is 0 to 100°.
