Description

Technical Field

[0001] The utility model relates to the technical field of water pumps and controllers, in particular to a linkage water pump with a split-type design of a water pump and a controller. Background Art

[0002] A linkage water pump usually refers to a system in which a water pump and other machines work together through some control method. For example, when a drilling machine, a cutting machine or other machine is in use, the water pump is running to spray water at the same time, so the water pump needs to be running while other machines are running. However, many of these water pumps are currently combined with controllers, which is very inconvenient to use, especially since the water pump needs to be connected to the water inlet and outlet pipes, and it is impossible to use a submersible pump to directly put the pump body into the water for use, so it cannot be used in some occasions.

[0003] For example, a linkage water pump control system disclosed in application No. 202322377726.4 adopts a split design, but the water pump is large in size and needs to be fixed on a base, which makes it inconvenient to move and use. Summary of the invention

[0004] The utility model aims to solve the problems existing in the prior art and provides a linkage water pump of split design. The water pump and the controller are separated, so different types of water pumps can be flexibly adopted, and the controller design is more compact and practical.

[0005] The utility model adopts a technical solution to solve the technical problem: a linkage water pump of split design, including a water pump and a linkage controller, and is characterized in that: the linkage controller includes a shell, an electrical connector connected to the water pump and a socket connected to other machines are installed on the outer side of the shell, a linkage circuit board built into the shell is provided between the electrical connector and the socket, and the linkage circuit board is connected to a control panel located on the outer side of the shell.

[0006] Preferably, the water pump is a micro brush submersible pump or a micro brushless submersible pump. Setting the water pump as a brush water pump or a brushless water pump enables the split water pump to work in different scenarios, thereby improving the practicability of the device.

[0007] Preferably, the housing is a polygonal structure, and the electrical connector, the socket and the control panel are respectively arranged on different sides. Providing the housing as a polygonal structure and arranging various devices on different sides can facilitate the user to distinguish.

[0008] Preferably, a groove is provided on one side or a corner of the housing, a connecting rod is fixed in the groove, and a hanging rope is connected to the connecting rod. The hanging rope can improve the portability of the water pump.

[0009] Preferably, a distance is provided between the linkage circuit board and the inner wall of the shell, the linkage circuit board is close to the control panel, and an electrical connector is installed at the side end of the linkage circuit board.

[0010] Preferably, the housing has a slot on the upper surface, and the control panel is embedded in the slot. The housing has a slot for installing the control panel, which can ensure the appearance and flatness of the linkage controller and protect the control panel to a certain extent.

[0011] Preferably, a limiting groove is provided on one side of the housing near the control panel to accommodate the linkage circuit board and limit the linkage circuit board in a fixed position. The limiting groove enables the linkage circuit board to be stably connected to the control panel and the electrical connector, and prevents the linkage controller from being disconnected from the control panel and the electrical connector during shaking, thereby improving the stability of the device.

[0012] Preferably, the electrical connector is a DC socket. Using a DC socket can effectively improve the performance and stability of the circuit.

[0013] Preferably, the housing is divided into an upper housing and a lower housing, the upper housing and the lower housing are connected by a fixing piece, and a sealing groove is provided at the connection between the upper housing and the lower housing. Disassembling the housing into the upper housing and the lower housing and connecting them by the fixing piece can facilitate disassembly and maintenance of the linkage control.

[0014] Preferably, the left and right corners of the upper shell and the left and right corners of the lower shell are provided with reinforcing ribs distributed in parallel. The provision of reinforcing ribs can improve the strength of the shell and prevent the shell from being damaged due to collision.

[0015] The beneficial effects of the utility model are as follows: the water pump and the linkage controller are separated, thereby improving the portability of the device; at the same time, the water pump is small in size, so the water pump can be taken to any place where it is needed, and it is convenient to use and has high practicality; and different types of water pumps can be used, thereby further improving the practicality of the device.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings:

[0022] See attached Figure 1 : A linkage water pump 1 with a split design includes a water pump 1 and a linkage controller 2. The linkage controller 2 includes a shell 3. An electrical connector 4 connected to the water pump 1 and a socket 5 connected to other machines are installed on the outer side of the shell 3. A linkage circuit board 6 built into the shell 3 is provided between the electrical connector 4 and the socket 5. The linkage circuit board 6 is connected to a control panel 7 located on the outer side of the shell 3.

[0023] The housing 3 is a polygonal structure, and the electrical connector 4, the socket 5 and the control panel 7 are respectively arranged on different sides. Figure 1 : In this embodiment, the overall frame of the shell 3 presents a hexahedral structure, including a pair of main mounting surfaces of the same area and larger, and a secondary mounting surface that includes the pair of main mounting surfaces to make the interior of the shell 3 in a sealed state. Since the volume of the socket 5 is large, the socket 5 is installed on a main mounting surface with a larger area, and the volume of the electrical connector 4 and the control panel 7 is small, so they are respectively installed on a secondary mounting surface. At the same time, when the linkage water pump 1 is in use, the linkage controller 2 needs to be placed in one place, and the hexahedral structure of the shell 3 can help the linkage controller 2 to be stably placed in one place.

[0024] At the same time, in order to improve its portability, a groove 8 is provided on one side or corner of the shell 3, a connecting rod 9 is fixed in the groove 8, a hanging rope 10 is connected to the connecting rod 9, a distance is provided between the linkage circuit board 6 and the inside of the shell 3, the linkage circuit board 6 is close to the control panel 7, and an electrical connector 4 is installed on the side end of the linkage circuit board 6.

[0025] Reference Figure 2 : Since the control panel 7 is an electronic component, its body is relatively fragile, and the linkage controller 2 may encounter unexpected situations, causing the linkage controller 2 to fall from a height. Therefore, in order to protect the control panel 7 and prevent it from being easily damaged when falling from a height, a card slot 11 is opened on the upper surface of the shell 3, and the control panel 7 is embedded in the card slot 11. The shell 3 is an injection molded part, which itself has a certain buffering function, which can further protect the internal control panel 7 from damage.

[0026] Reference Figure 3: In the linkage water pump, the linkage relationship between the machine in use and the water pump 1 is handled by the linkage circuit board 6 arranged inside the linkage controller 2. In order to ensure that the linkage circuit board 6 can handle the linkage relationship between the machine in use and the water pump 1, a limiting groove 12 for accommodating the linkage circuit board 6 and limiting the linkage circuit board 6 in a fixed position is provided on one side of the shell 3 close to the control panel 7. By limiting the installation of the linkage circuit board 6, it is ensured that the linkage circuit board 6 can be stably connected to the water pump 1 and the machine in use.

[0027] In order to further improve the practicality of the device, the water pump 1 can be replaced with a micro brush submersible pump or a micro brushless submersible pump according to different usage scenarios. The micro brushless water pump has better performance and less noise and is suitable for use in areas that require quietness, but its price is relatively high, resulting in a high cost of use. The performance of the micro brush water pump is weaker than that of the micro brushless water pump and has certain noise, but it is cheap and has a low cost of use. The weight of the micro brushless water pump and the micro brush water pump is no more than 0.5kg.

[0028] The electrical connector 4 used in this embodiment is a DC socket, wherein the DC plug is a cylindrical structure, which has a simple structure and is easy to connect. At the same time, the circuit has high stability and is not easy to be damaged, thereby improving the durability of the device.

[0029] In order to facilitate the installation and maintenance of the linkage controller 2, the shell 3 is divided into an upper shell 13 and a lower shell 14. The upper shell 13 and the lower shell 14 are connected by a fixing member 15. A sealing groove 16 is provided at the connection between the upper shell 13 and the lower shell 14. Specifically, the fixing member 15 in this embodiment can be a screw, and a threaded hole that cooperates with the fixing member 15 is installed in the sealing groove 16.

[0030] In this embodiment, the shell 3 is an injection molded part, and the hardness of the material itself is relatively average. In order to improve the structural strength, parallel reinforcement ribs 17 are provided at the left and right corners of the upper shell 13 and the left and right corners of the lower shell 14.

[0031] The following is the circuit diagram principle of the linkage circuit board 6:

[0032] Reference Figure 4 : 1. AC1 and AC2 are 220V~ power input. One of the lines (AC1 or AC2) passes through the current transformer in the circuit board, and then AC1 and AC2 are connected to the AC line on the circuit board respectively and then connected to socket 5.

[0033] 2. Plug the submersible pump power cord into the electrical connector 4.

[0034] The linkage water pump has two linkage modes. When the switch on the control panel 7 is pressed to the "0" position, it is the linkage mode. At this time, the water pump and the machine used (such as a slotting machine, a water drill, etc.) are started together; when the switch on the control panel 7 is pressed to the "1" position, it is the manual mode, and the water pump 1 is started directly.

[0035] The principles used are as follows:

[0036] In linkage mode, when the machine starts, the current transformer detects that there is current passing through (generally greater than 40W), connects the low-voltage power supply on the circuit board, and water pump 1 starts working; conversely, when the machine is shut down, the current transformer detects that there is no current passing through, cuts off the low-voltage power supply, and water pump 1 stops working.

[0037] Certain words are used in the specification and claims of this utility model to refer to specific products. It should be understood by those with ordinary knowledge in the art that manufacturers may refer to the same components by different names. This document does not intend to distinguish between components that have the same function but different names.

[0038] The above are preferred embodiments of the present invention.
