Description

Technical Field

[0001] The utility model relates to the technical field of liquid supply weighing, in particular to a portable liquid weighing device. Background Art

[0002] The weighing devices currently used in factories are mainly electronic scales and fast weighing spoons, which can only weigh solid materials. For example, a large barrel of liquid material of 25kg requires two or three people to lift it, pour the liquid out of the container, and then transfer it to the electronic scale for weighing. This method is labor-intensive and time-consuming, and will also cause material loss.

[0003] In existing technologies, water pumps can measure liquid flow using a flow meter. Since the density of the liquid is known, the weight of the liquid extracted can be calculated, eliminating the need to pour out the liquid, which reduces waste. Furthermore, the amount of liquid extracted per operation can be set via a program, allowing for convenient quantitative liquid extraction. However, in factories, after liquid extraction is completed, the pump device needs to be packaged and protected, and cannot be left unused for long periods of time. Existing liquid extraction and metering devices are inconvenient to carry and store, a problem that needs to be addressed. Utility Model Content

[0029] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0030] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

After the water outlet pipe 3 is pulled out from the socket 102, it is carded in the card slot 103.

[0032] During use, the water pipe 203 is placed in the barreled liquid. As the liquid pump 2 draws the liquid, the flow rate is measured by the flowmeter 201, enabling accurate sampling and converting the flow rate into a weight parameter. The socket 102 can be located in the middle or side of the upper end of the housing 1. The lower portion of the water outlet pipe 3 is inserted into the socket 102, and the positioning plate 301 is inserted into the first slot 1021 to position the water outlet pipe 3. The water outlet pipe 3 is now arranged in the radial direction of the housing 1 and extends outward.

[0033] After sampling is completed, the weighing device can be removed, and the water outlet pipe 3 can be pulled out from the socket 102. The flow meter 201 is located in the housing 1. The connecting pipe 202 is passed through the socket 102. The connecting pipe 202 is a flexible hose structure. Then, the water outlet pipe 3 can be snapped into the slot 103. The slot 103 can be arc-shaped and located in the outer wall of the housing 1.

[0034] The socket 102 can be connected to the outside of the side wall of the housing 1 to accommodate the bent connecting tube 202. A redundant connecting tube 202 can be provided inside the housing 1 to facilitate the movement of the connecting tube 202 with the removed water outlet pipe 3, thereby maintaining the connection between the water outlet pipe 3 and the water outlet end of the flow meter 201. This eliminates the need for repeated plugging and connection, thereby maintaining a tight seal. The connecting tube 202 can be plugged and sealed with the socket 102.

[0035] Furthermore, it also includes: a sleeve 4, which is arranged at the lower end of the casing 1 and is sleeved on the outside of the water pumping pipe 203; a fixing seat 5, which is arranged at the lower end of the casing 1 and is located next to the water pumping pipe 203, and the fixing seat 5 has a fixing groove 501 that is gap-matched with the sleeve 4. The sleeve 4 is used to bend the water pumping pipe 203 and then insert it into the fixing groove 501.

[0036] In use, sleeve pipe 4 can be circular or straight notch shape or oval or rectangular etc. When extracting liquid, sleeve pipe 4 can be plugged in casing 1 lower end and fixed, and is sleeved on water-drawing pipe 203 outside. After finishing pumping liquid, sleeve pipe 4 can be removed from casing 1, but sleeve pipe 4 is still sleeved on water-drawing pipe 203 outside and sleeve pipe 4 can move down along water-drawing pipe 203, water-drawing pipe 203 is bent upwards to form " V " font and clamp sleeve pipe 4 bottoms subsequently, after sleeve pipe 4 bottoms can be turned upwards then, insert in the fixing groove 501, water-drawing pipe 203 is squeezed between sleeve pipe 4 and fixing groove 501 inwalls, play fixing role, this moment, water-drawing pipe 203 vertical height shortens, is easy to carry, and water-drawing pipe 203 bending parts play sealing role, can reduce the overflow of water in liquid pump 2 inside and pipeline, more clean and tidy.

[0037] Of course, when the sleeve 4 can also be of an elliptical structure, the water pumping pipe 203 is bent into a broken line shape and inserted into the sleeve 4 for storage (the positioning sleeve 101 is used to be mounted on the mouth of the bucket, and has a larger diameter to accommodate the water pumping pipe 203, but the fixing effect is poor, and the water pumping pipe 203 is easy to spread and bounce open).

[0038] Furthermore, two liquid pumps 2 are provided, and the water outlet end of each liquid pump 2 is connected to a flow meter 201. There are two water outlet pipes 3, and the water outlet end of each flow meter 201 is connected to a water outlet pipe 3. The two water outlet pipes 3 are respectively inserted into both sides of the upper end of the casing 1.

[0039] When in use, the liquid pump 2, the flow meter 201 and the pipeline structure form a set of water pumping components. Two sets of water pumping components are provided, and the two water outlet pipes 3 can be controlled separately, so that liquid can be taken separately without affecting each other, which is more efficient. When taking liquid at the same time, liquid can be taken quickly and in large quantities.

[0040] Plug holes 102 are provided on both the left and right sides of the upper end of the casing 1 , and the two water outlet pipes 3 are respectively plugged into the jacks 102 on both sides.

[0041] Furthermore, the water inlet end of each liquid pump 2 is connected to a water pumping pipe 203, the sleeve 4 is sleeved on the outside of the two water pumping pipes 203, the fixing seat 5 is located between the two water pumping pipes 203, and the upper end of the sleeve 4 has an avoidance groove 401 that is plugged and adapted to the fixing seat 5.

[0042] When in use, when two pumping assemblies are provided, the sleeve 4 can be bent and stored simultaneously for both pumping pipes 203. At this point, the fixing base 5 is located between the two pumping pipes 203. During pumping, the sleeve 4 can be plugged into the two pumping pipes 203 or plugged into the lower end of the housing 1, or plugged into the fixing base 5 via the avoidance groove 401. When stored, the sleeve 4 can be removed and plugged into the fixing base 5.

[0043] The fixing seat 5 is adapted to the shape of the sleeve 4, and the inner wall of the fixing groove 501 can be spaced apart from a portion of the outer wall of the sleeve 4 to facilitate the entry of the bent water pumping pipe 203.

[0044] Furthermore, the slot 103 is annular, and the cross section of the slot 103 is “C”-shaped.

[0045] When in use, the outlet pipe 3 is clamped in the clamping groove 103 to achieve fixation. When two sets of pumping components are set, the clamping groove 103 is annularly arranged along the outer wall of the casing 1, and the outlet pipe 3 is smaller than a semicircle, so that the two outlet pipes 3 can be clamped in the clamping groove 103 at the same time.

[0046] Furthermore, a second slot 1022 is vertically provided on one side of the jack 102 , and the second slot 1022 is perpendicular to the first slot 1021 .

[0047] During use, when the positioning plate 301 of the water outlet pipe 3 is inserted into the first slot 1021, the water outlet pipe 3 as a whole extends outward in the radial direction of the housing 1, with the left and right water outlet pipes 3 facing the sides respectively. When the positioning plate 301 is inserted into the second slot 1022, the left and right water outlet pipes 3 can face the front or rear at the same time.

[0048] Furthermore, the housing 1 has a control panel 104 .

[0049] When in use, the structures and control systems such as the water pump, control panel 104 and flow meter 201 are existing technologies. The control panel 104 can control the water pump switch and select the single liquid pumping amount, etc., to achieve single quantitative liquid extraction, which is more convenient to use.
