Description

Technical Field

[0001] This utility model relates to the technical field of quantitative liquid discharge mechanism for pump heads, specifically a quantitative liquid discharge mechanism based on a pump head. Background Technology

[0002] In fields such as chemical engineering, pharmaceuticals, environmental protection, food processing, and laboratory research, many process steps (such as reagent preparation, drug addition, sample collection, and wastewater treatment) have strict requirements for the quantitative delivery accuracy of liquids. For example, deviations in the amount of reagents added in chemical reactions may lead to a decrease in product purity; errors in sampling volume in environmental monitoring may affect the accuracy of data; and the quantitative filling of pharmaceutical solutions in pharmaceutical production is directly related to the safety of drug dosage.

[0003] Existing pump heads typically use impellers and blades to transport liquids. The rotation of the blades drives the liquid out, but they do not have the effect of quantitative discharge. Some pump heads with quantitative discharge structures often require more sensors for control, which increases costs and makes the structure more complex.

[0004] Therefore, a quantitative discharge mechanism based on the pump head is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a quantitative drainage mechanism based on a pump head. This mechanism solves the problems of existing pump heads, which typically transport liquids through impellers and blades, and discharge liquids by rotating the blades, without achieving quantitative drainage. Furthermore, some pump heads with quantitative drainage structures often require more sensors for control, resulting in higher costs and more complex structures.

[0006] To achieve the above objectives, this utility model provides the following technical solution: it includes a pump head, a water outlet pipe is fixedly connected to the outlet of the pump head, a liquid collection tank is fixedly connected to one end of the water outlet pipe, a drain port is provided at the bottom of the liquid collection tank, a solenoid valve is fixedly connected to the drain port, a flow guide surface is provided inside the liquid collection tank, a sliding resistor is fixedly connected to the outside of the liquid collection tank, and a transmission mechanism is provided inside the liquid collection tank.

[0007] Preferably, the guide surface is located at the bottom of the inner cavity of the liquid collection tank, and there are two guide surfaces, which are inclined surfaces.

[0008] Preferably, the transmission mechanism includes a guide rod, a paddle, a first fixed rod, a second fixed rod, a float, a frame plate, and a through groove. The guide rod is fixedly connected to the outside of the sliding resistor, the paddle is slidably connected to the outside of the guide rod, the first fixed rod is fixedly connected to the outside of the paddle, the second fixed rod is fixedly connected to one end of the first fixed rod, the float is fixedly connected to one end of the second fixed rod, the frame plate is fixedly connected to the inside of the liquid collection tank, two frame plates are provided, and the through groove is provided between the two frame plates.

[0009] Preferably, the frame plate is configured with an arc shape, and the float is disposed between the two frame plates.

[0010] Preferably, the second fixing rod is slidably connected through the liquid collection tank, and a control mechanism is provided at one end of the second fixing rod.

[0011] Preferably, the control mechanism includes a side plate, a fixing frame, a first switch and a second switch. The side plate is fixedly connected to one end of a second fixing rod, the fixing frame is fixedly connected to the top of the liquid collection tank, the first switch is fixedly connected to the inner bottom of the fixing frame, and the second switch is fixedly connected to the inner bottom of the fixing frame.

[0012] Preferably, the side plate has a T-shaped structure and is located inside the fixing frame. The first switch and the second switch are electrically connected to the solenoid valve.

[0013] Compared with the prior art, this utility model provides a quantitative liquid discharge mechanism based on a pump head, which has the following beneficial effects:

[0014] 1. After the liquid enters the collection tank, the rise in liquid level causes the float to rise, which in turn causes the lever to slide outside the sliding resistor. As the liquid level rises, the voltage of the water pump is adjusted accordingly, changing the speed of the water pump, until the float rises to the top of the inner cavity of the collection tank. At this time, the water pump is shut off by controlling the sliding resistor, thus achieving the effect of quantitative output of liquid.

[0015] 2. When the float rises to the top of the liquid collection tank, the water pump stops. At this time, press the second switch on the side panel to open the solenoid valve and quickly discharge the liquid. During discharge, the float falls naturally. Through the setting of the sliding resistor, the water pump speed slowly increases, and the water discharge time is about ten seconds. At this time, the water inside the liquid collection tank is completely discharged. Press the first switch on the side panel to close the solenoid valve and close the water storage, thereby achieving the effect of quantitative liquid discharge. Attached Figure Description

[0021] 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.

[0022] Example:

[0023] Please see Figure 1 - Figure 4 The pump head-based quantitative drainage mechanism in this embodiment includes a pump head 1, an outlet pipe 2 fixedly connected to the outlet of the pump head 1, a collection tank 3 fixedly connected to one end of the outlet pipe 2, a drainage port at the bottom of the collection tank 3, a solenoid valve 4 fixedly connected to the drainage port, a flow guide surface 5 inside the collection tank 3, a sliding resistor 6 fixedly connected to the outside of the collection tank 3, and a transmission mechanism inside the collection tank 3, which includes a guide rod 7, a lever 8, a first fixed rod 9, a second fixed rod 10, and a float 11. The slide resistor 6 is fixedly connected to the outside of the slide resistor 6, and the lever 8 is slidably connected to the outside of the guide rod 7. The first fixing rod 9 is fixedly connected to the outside of the lever 8, and the second fixing rod 10 is fixedly connected to one end of the first fixing rod 9. The float 11 is fixedly connected to one end of the second fixing rod 10. The slide resistor 6 is fixedly connected to the inside of the liquid collection tank 3. There are two slide resistors 16. The through groove 17 is located between the two slide resistors 16. The lever 8 is a structure that is built into the slide resistor 6. Its principle is existing technology.

[0024] In use, the pump head 1 supplies liquid to the liquid collection tank 3 through the outlet pipe 2. After the liquid enters the liquid collection tank 3, the rise in liquid level causes the float ball 11 to float, thereby pushing the second fixed rod 10 to slide upward. The sliding of the second fixed rod 10 simultaneously drives the first fixed rod 9 to slide, thereby causing the lever 8 to slide outside the sliding resistor 6. At the same time as sliding, the rise in liquid level adjusts the voltage of the water pump and changes the speed of the water pump until the float ball 11 rises to the top of the inner cavity of the liquid collection tank 3. At this time, the water pump is turned off by controlling the sliding resistor 6, thus achieving the effect of quantitative output of liquid.

[0025] Please see Figure 1 - Figure 4 The guide surface 5 is set at the bottom of the inner cavity of the liquid collection tank 3. There are two guide surfaces 5. The guide surface 5 is set as an inclined surface. The frame plate 16 is set as an arc structure. The float ball 11 is set between the two frame plates 16. The second fixing rod 10 slides through and connects to the liquid collection tank 3. One end of the second fixing rod 10 is set with a control mechanism.

[0026] To facilitate quantitative delivery, the control mechanism includes a side plate 12, a fixing frame 13, a first switch 14, and a second switch 15. The side plate 12 is fixedly connected to one end of the second fixing rod 10, the fixing frame 13 is fixedly connected to the top of the liquid collection tank 3, the first switch 14 is fixedly connected to the inner bottom of the fixing frame 13, and the second switch 15 is fixedly connected to the inner bottom of the fixing frame 13.

[0027] When the float 11 rises to the top of the inner cavity of the liquid collection tank 3, the water pump stops. At this time, the side plate 12 presses the second switch 15 to control the solenoid valve 4 to open, and the liquid is discharged quickly. During the discharge, the float 11 falls naturally. Through the setting of the sliding resistor 6, the water pump speed is slowly increased, and the water discharge time is about ten seconds. At this time, the water inside the liquid collection tank 3 is completely discharged. The side plate 12 presses the first switch 14 to control the solenoid valve 4 to close the water storage, thereby achieving the effect of quantitative liquid discharge.

[0028] Please see Figure 3 The side plate 12 has a T-shaped structure and is located inside the fixing frame 13. The first switch 14 and the second switch 15 are electrically connected to the solenoid valve 4.

[0029] The working principle of the above embodiments is as follows:

[0030] In use, the pump head 1 supplies liquid to the liquid collection tank 3 through the water outlet pipe 2. After the liquid enters the liquid collection tank 3, the rise in liquid level causes the float ball 11 to float up, thereby pushing the second fixed rod 10 to slide upward. The sliding of the second fixed rod 10 simultaneously drives the first fixed rod 9 to slide, thereby causing the lever 8 to slide outside the sliding resistor 6. While sliding, the rise in liquid level adjusts the voltage of the water pump and changes the speed of the water pump until the float ball 11 rises to the top of the inner cavity of the liquid collection tank 3. At this time, the sliding resistor 6 controls the water pump to shut off, achieving the effect of quantitative output of liquid.

[0031] When the float 11 rises to the top of the inner cavity of the liquid collection tank 3, the water pump stops. At this time, the side plate 12 presses the second switch 15 to control the solenoid valve 4 to open, and the liquid is discharged quickly. During the discharge, the float 11 falls naturally. Through the setting of the sliding resistor 6, the water pump speed is slowly increased, and the water discharge time is about ten seconds. At this time, the water inside the liquid collection tank 3 is completely discharged. The side plate 12 presses the first switch 14 to control the solenoid valve 4 to close the water storage, thereby achieving the effect of quantitative liquid discharge.

[0032] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0033] 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.
