Description

TECHNICAL FIELD

[0001] The utility model relates to a water pump, in particular to a hand -operated water pump intelligent controller. BACKGROUND

[0002] At present, the Chinese patent with the authorization announcement number CN210919412U discloses a novel electronic timing water pump controller, which comprises a box cover, a box body, a binding post fixing plate, a capacitor and a control board, the box cover and the box body are fixed by screws, the periphery of the box cover and the box body is sealed by resin, the box body is provided with a slot, and the binding post fixing plate is fixed with a motor connecting socket on one side.

[0003] The control board is provided with a reed tube and a single-chip microcomputer, the reed tube detects the water flow switch signal on the external motor, controls the rotation of the motor and the water pumping work of the water pump, the single-chip microcomputer controls the working time of the water pump motor, and the water pump motor is forcibly started for 3 seconds at a specific time, so that the water pump will not be blocked even in a long time of non-use, and the normal work of the equipment is ensured, and the installation and use are convenient.

[0004] However, the reed tube is easy to be damaged, the stability is not high, and the maintenance cost is high. UTILITY MODEL CONTENT

[0005] Therefore, the utility model aims at providing a hand -operated water pump intelligent controller, which has high stability and low maintenance cost.

[0006] In order to solve the above technical problems, the technical scheme of the utility model is as follows: a hand -operated water pump intelligent controller, which comprises an outer shell, a water inlet pipe and a water outlet pipe are formed in the outer shell, a water flow area communicated with the water inlet pipe and the water outlet pipe is formed in the outer shell, a fixing pipe is connected to the outer shell, a sliding column is slidably connected in the fixing pipe, an adjusting part is threadedly connected to the fixing pipe, an elastic part is connected between the adjusting part and the sliding column, a displacement part is slidably connected to the side wall of the fixing pipe, a switch is connected to the outer shell, a waterproof membrane is sealingly connected between the fixing pipe and the water flow area, and the sliding column is in abutment with the waterproof membrane through the elastic force of the elastic part.

[0007] The sliding column moves along the axial direction of the fixing pipe and pushes the displacement part, so that the displacement part triggers the switch.

[0008] To implement the above technical solution, water is injected into the outer shell from the water inlet pipe and then discharged from the water outlet pipe. At this time, the water will generate water pressure on the sliding column. When the water pressure is greater than the elastic force of the elastic member, the sliding column moves along the axial direction of the fixed tube, causing the sliding column to push the displacement member to move. The displacement member triggers the switch, and the switch sends an electrical signal, which is transmitted to the water pump to stop the water pump and reduce the water pressure. After the water pump stops working for a period of time, the water pressure drops. At this time, because the elastic force of the elastic member is greater than the water pressure, the sliding column moves along the fixed tube away from the displacement member. The displacement member cannot trigger the switch. The switch sends an electrical signal to the water pump, and the water pump starts working, thereby achieving the purpose of maintaining water pressure. And because of the mechanical structure, it has high operational stability, low maintenance cost and low production cost; the provision of the waterproof membrane improves the waterproof effect, and can limit the water in the water flow area from entering the fixed pipe, thereby not easily causing damage to the switch, and the waterproof membrane itself is elastic, so the waterproof membrane can deform to drive the sliding column to move; when the adjusting part is rotated and the adjusting part moves in the direction closer to the sliding column, the deformation amount and elastic force of the elastic part increase, and therefore, the water pressure required to move the sliding column increases; similarly, when the adjusting part moves in the direction away from the sliding column, the elastic force of the elastic part on the sliding column decreases, and the water pressure required to move the sliding column decreases, thereby achieving the purpose of regulating the water pressure.

[0009] As a preferred solution of the present invention, the adjusting member is connected to a first limiting column, the sliding column is connected to a second limiting column, and both ends of the elastic member are respectively sleeved on the first limiting column and the second limiting column.

[0010] By implementing the above technical solution, the elastic member is not easily moved.

[0011] As a preferred solution of the present invention, the adjusting member is connected to a connecting sleeve, which is located outside the fixed tube. The connecting sleeve is connected to a protective tube, which is sleeved outside the fixed tube.

[0012] By implementing the above technical solution, the protective tube improves the protective effect on the fixed tube.

[0013] As a preferred solution of the present invention, a knob is rotatably connected to the housing, the knob is connected to the connecting sleeve, and the knob drives the adjusting member to rotate through the connecting sleeve.

[0014] To implement the above technical solution, the adjusting member is rotated by turning the knob, thereby achieving the purpose of adjusting the water pressure, and the operation is simpler.

[0015] As a preferred solution of the present invention, the end of the sliding column is fixedly connected to a contact plate, the cross-sectional area of ​​the contact plate is larger than the cross-sectional area of ​​the sliding column, and the waterproof membrane is in contact with the contact plate.

[0016] The implementation of the above technical solution makes the waterproof membrane less susceptible to damage and at the same time enables the sliding column to move more smoothly in the fixed tube.

[0017] As a preferred solution of the present invention, the displacement member includes a steel ball.

[0018] By implementing the above technical solution, the contact area between the steel ball and the fixed tube is small, the steel ball moves more sensitively and has less wear, thereby improving the structural stability and service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0025] A manually adjustable intelligent water pump controller includes a housing 1 and a circuit board 2. The circuit board 2 is electrically connected to the water pump. A water inlet pipe 11 and a water outlet pipe 12 are formed on the sidewalls of the housing 1, and a cavity is defined within the housing 1. The cavity communicates with the water inlet pipe 11 and the water outlet pipe 12. A partition 3 is fixedly connected to the interior of the housing 1, and the circuit board 2 is fixed to the partition 3. The circuit board 2 is located on one side of the partition 3, and the water inlet pipe 11 and the water outlet pipe 12 are located on the other side of the partition 3. The partition 3 divides the cavity into an electronics area 31 and a water flow area 32.

[0026] A fixed tube 4 is fixedly connected to the partition 3, connecting the electronic area 31 and the water flow area 32, and extending toward the electronic area 31. A sliding column 41 is slidably connected to the fixed tube 4, and the sliding column 41 moves along the axial direction of the fixed tube 4. A sliding hole 42 is provided on the side wall of the fixed tube 4, connecting the inner wall and the outer wall of the fixed tube 4. A displacement member 44 is slidably connected in the sliding hole 42, and the displacement member 44 is a steel ball. A switch 45 is fixedly connected to the partition 3 near the displacement member 44, and the switch 45 is used to connect to the circuit board 2. The switch 45 is a micro switch 45.

[0027] The sliding column 41 is provided with an L-shaped slot 411 . The outer wall of one side of the displacement member 44 contacts the side wall of the slot 411 . The displacement member 44 is located in the sliding hole 42 . The outer wall of the other side of the displacement member 44 contacts the switch 45 .

[0028] A rubber waterproof membrane 43 is fixedly attached to the end of the fixed tube 4 near the water flow area 32 to prevent water from entering the electronic area 31 through the fixed tube 4. A contact plate 412 is integrally connected to the end of the sliding post 41. The cross-sectional area of ​​the contact plate 412 is larger than that of the sliding post 41, and the waterproof membrane 43 contacts the contact plate 412.

[0029] An adjusting member 5 is threadedly connected to the fixed tube 4. A first limiting post 51 is fixedly connected to the end of the adjusting member 5 that faces the sliding post 41. The first limiting post 51 is coaxially arranged with the adjusting member 5. A second limiting post 52 is fixedly connected to the end of the sliding post 41 that faces the adjusting member 5. The ends of an elastic member 53 are respectively sleeved on the first limiting post 51 and the second limiting post 52. The elastic member 53 is a spring.

[0030] In this manner, water flows from the water inlet pipe 11 into the water flow area 32 and is then discharged from the water outlet pipe 12. During this process, the water exerts pressure on the waterproof membrane 43. When this pressure exceeds the elastic force of the elastic member 53, the waterproof membrane 43 deforms, driving the slide post 41 toward the adjustment member 5 through the contact plate 412. The sidewall of the slide post 41 contacts the outer wall of the displacement member 44, causing the displacement member 44 to move toward the switch 45. This pressure exerts pressure on the switch 45, causing the switch 45 to send an electrical signal to the circuit board 2, which in turn sends an electrical signal to the water pump, causing the water pump to stop.

[0031] Similarly, when the water pump has been idle for a period of time and the water pressure drops, when the water pressure on the slide post 41 is less than the elastic force of the elastic member 53, the elastic force of the elastic member 53 causes the slide post 41 to move downward along the fixed tube 4, separating the side wall of the slide post 41 from the displacement member 44. The spring on the micro switch 45 exerts an elastic force on the displacement member 44, causing it to reposition in the slot 411. At this point, the micro switch 45 sends an electrical signal to the circuit board 2, which in turn sends an electrical signal to the water pump, turning it on and increasing the water pressure, thereby maintaining the water pressure.

[0032] Therefore, the closer the adjusting member 5 moves to the sliding column 41 , the higher the water pressure maintained, and vice versa.

[0033] This patent application adopts a mechanical structure, which is stable, reliable and has low production cost.

[0034] A connecting sleeve 6 is fixedly connected to the adjusting member 5 and is located outside the fixed tube 4. A protective tube 61 is fixedly connected to the outer wall of the connecting sleeve 6 and is sleeved around the outside of the fixed tube 4. The arrangement of the connecting sleeve 6, protective tube 61, and waterproof membrane 43 prevents foreign matter from entering the fixed tube 4.

[0035] A knob 7 is rotatably connected to the housing 1, and the knob 7 is fixedly connected to the connecting sleeve 6. The adjusting member 5 can be moved by rotating the knob 7. The adjusting member 5 can be self-positioned in the fixed tube 4 by the self-locking property of the thread.

[0036] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
