Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The invention relates in particular to a measuring cup which can also be weighed.

[0002]

[Prior art]

 As a conventional measuring cup that can also measure weight, it is known that the value converted from the volume of each measured object is written along with the scale for measuring the volume on the side of the measuring cup. There is. In the case of the above measuring cup, for example, when trying to measure the weight and volume of flour, put the flour into the measuring cup, first look at the volume scale provided on the side of the measuring cup to know the volume, and then Know the weight by looking at the scale on which the volume is converted to weight.

However, in the above case, the types of weight-converted values of the volume of the object to be measured that can be marked on the side surface of the measuring cup are limited, and it is not possible to know the weight of any type. . In addition, the weight can be measured only for liquids or powders, and the weight of solids cannot be measured.

Therefore, it is considered that a weighing scale is attached to the bottom of the measuring cup, but in the case of the measuring cup, if it is not heavy enough to be carried by one hand, for example, the volume of the liquid is measured and other Emptying the liquid in the measuring cup can be very difficult when transferring to another container. In addition, since the weighing scale is usually vulnerable to vibration, if the weighing scale is mounted on a measuring cup that is frequently held in the hand, the accuracy of the weighing scale may deteriorate.

[0005]

[Problems to be solved by the device]

 An object of the present invention is to provide a measuring cup which is small and light and has a vibration resistant scale attached to the bottom thereof.

[0006]

[Means for Solving the Problems]

 According to the present invention, a detachable portion for attaching and detaching a measuring cup, a support plate for supporting the detachable portion, a spring having one end attached to the detachable portion, and a semiconductor force sensor having the other end of the spring attached thereto. The above-mentioned problems are solved by attaching a measuring cup to a weighing scale including a sensor.

[0007]

[Work]

 When the object to be measured is placed in the measuring cup, the two support plates are deformed and the tension applied to the spring connecting the detachable part and the semiconductor force sensor changes, and this change in tension is detected by the semiconductor force sensor. By doing so, the weight of the object to be measured is measured.

 FIG. 1 is a side view showing an example of a measuring cup according to the present invention, and FIG. 2 is a sectional view. Reference numeral 1 is a transparent measuring cup having a fitting portion on the lower portion and a scale 1a for measuring the volume on the side surface, and 2 is a detachable portion having a fitting portion capable of fitting with the fitting portion of the measuring cup 1. An attachment part, 3 is a weight scale main body having a waterproof function, 4 is an elastically deformable upper support plate, 5 is an elastically deformable lower support plate having the same shape as the upper support plate 4, and 6 is an upper support plate 4 and a lower support plate. An overload prevention ring mounted with a space between the side support plates 5, 7 is a connecting member connecting the upper support plate 4 and the lower support plate 5, and 8 is a semi-conductor force attached to the bottom surface of the weighing machine main body. Sensor, 9 is a hook as a tension transmitting member attached to the detachable part 2 so as to be movable up and down, 10 is an adjusting screw for moving the hook 9 up and down, 11 is a hook with one end in a stretched state, and the other. Coil sp with its end attached to the working part of the semiconductor force sensor 8. , 12 is an L-shaped handle attached to the scale body 3, 13 is a battery mounted in the handle, 14 is a power switch for driving the scale provided on the handle 12, 15 is an IC, etc. A circuit board 16 on which is mounted is a liquid crystal display device 16 for displaying a weight measurement value.

Next, the circuit configuration of the above embodiment will be described with reference to FIG. The voltage of the battery 13 is boosted by the DC / DC converter 17, the current and voltage are stabilized by the constant voltage circuit 18 and the constant current circuit 19, and power is supplied to the semiconductor force sensor 8 shown by the broken line.

Then, the output from the semiconductor force sensor 8 is adjusted by the zero reset circuit 20 so that a signal indicating zero can be taken out when the measuring cup 1 is empty, and the analog signal is converted by the A / D converter 21. After being converted into a digital signal, the weight measurement value is digitally displayed on the liquid crystal display device 16.

Next, the structure of the upper support plate 4 and the lower support plate 5 will be described. Although FIG. 4 is a plan view of the upper support plate 4, the lower support plate 5 has exactly the same shape as the upper support plate 4, so that only the upper support plate 4 and the lower support plate 5 are shown in FIG. Explain.

The outer peripheral portion 4 a of the upper support plate is fixed to the upper side of the overload prevention ring 6 with a screw or the like via a hole 4 c, and the inner peripheral portion 4 b has a hole 4 c between the detachable portion 2 and the connecting member 7. It is fixed with a screw or the like. The outer peripheral portion 5a of the lower support plate is fixed to the lower side of the overload prevention ring 6 with a screw or the like through the hole 5a, and the inner support plate 5b is fixed to the connecting member 7 with a screw or the like through the hole 5d. ing.

Reference numerals 4e and 5e denote support legs, which connect the outer peripheral portions 4a, 5a and the inner peripheral portions 4b, 5b, and the support legs 4e, 5e are substantially spiral as shown in FIG. 4 in order to make them as long as possible. I am in a state. The support legs 4e, 5e are provided at equal intervals on the outer peripheral portions 4a, 5a and the inner peripheral portions 4b, 5b. The upper leg 4e and the lower leg 5e are attached to the main body of the weighing scale so that the upper leg 4e and the lower leg 5e have substantially the same spiral direction of rotation.

Next, the operation of the above embodiment will be described. First, when the measuring object is put into the measuring cup 1, the supporting legs 4e and 5e of the upper supporting plate 4 and the lower supporting plate 5 are elastically deformed by the weight of the measuring object. The longer the support legs 4e and 5e are, the larger the elastically deformable amount is, and the measurement accuracy is improved. As shown in FIG. 2, the upper support plate 4 and the lower support plate 5 are connected by the connecting member 7, so that even if an unbalanced load is applied to the measuring cup 1, the measuring cup 1 will move straight down. Moving.

However, since the overload prevention ring 6 is provided between the upper support plate 4 and the lower support plate 5, even if an object having a certain weight or more is put in the measuring cup 1, the upper support plate 4 is Since the supporting leg 4e comes into contact with the overload prevention ring 6 and is not further elastically deformed, even if a very heavy object is put in the measuring cup 1, the supporting legs 4e of the upper support plate and the lower support plate, 5e does not permanently deform.

When the measuring cup 1 moves downward, the tension applied to the coil spring 11 decreases, and the change in the tension is detected by the semiconductor force sensor 8 and converted into weight, which is displayed on the liquid crystal display device 21. .

To explain an example of how to use the above-mentioned embodiment, for example, when it is desired to know the volume and weight of a liquid, but there is no flat place nearby, the weighing cup of the present invention can be used to Lift the measuring cup by holding the handle 12, put the liquid to be measured in the measuring cup 1, and make the line of the scale 1a provided on the side surface of the measuring cup 1 parallel to the liquid surface. The capacity is measured, and then the weight is measured by looking at the liquid crystal display device 16 while keeping the measuring cup as it is.
