[0054] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. It should be noted that, in order to facilitate description, in the current view, the "left side" is the "first end", the "right side" is the "second end", the "upper side" is the "first end", and the "lower side" is the "second end". The purpose of such description is to clearly express the technical solutions, and it should not be understood as an improper limitation on the technical solutions of the application.
[0055] The utility model solves the technical problem of the influence of the generated foam bubbles on measurement in the prior art by using a measuring container, and provides a measuring container of a dispenser testing device. In the oil filling process, the generation of foam bubbles is related to various factors. Since the testing of the dispenser requires injecting a specified value of the detected oil into the measuring container through the oil filling gun, the causes of the generation of foam bubbles in the process include three types, specifically:
[0056] Cause (1) surface tension effect. The surface tension exists on the surface of the liquid, which is caused by the attraction between the liquid molecules. This surface tension enables the formation of foam;
[0057] Cause (2) instantaneous gas pressure. In the foam, the gas molecules are surrounded by the liquid molecules, forming a gas pressure;
[0058] Cause (3) pressure difference. When the foam is in a smaller container or is extruded by an external force, the gas molecules inside the foam will be subjected to greater pressure. This pressure difference will cause an upward net force on the surface of the foam;
[0059] Among the above three cases, the instantaneous gas pressure has relatively small influence on the measurement and testing of the dispenser. The disposal method of the technical solution is as follows: Figure 1 As shown in the accompanying drawings, the measuring container of the dispenser testing device comprises:
[0060] A main container body 1 is supported by a support frame 10. The bottom of the main container body 1 is provided with an oil discharge port 11, and the main container body 1 serves as a basis for quantitative storage for testing. The main container body 1 is mainly measured by the liquid level in the measuring neck 2;
[0061] The metering neck 2 is configured in a cylindrical shape, which is connected above the main container body 1, and the upper end of the metering neck 2 is provided with an oil inlet part 21; a liquid level tube assembly 20 is connected to the metering neck 2, which is used to communicate the metering neck 2 and read the liquid level of the liquid level tube assembly 20;
[0062] The flow guide part 3 is arranged on the extension end of the metering neck 2 formed in the main container body 1; the flow guide part 3 mainly handles the case of (1), that is, the surface tension of the oil liquid in the oiling process is guided, so as to reduce the formation of floating foam;
[0063] For the pressure difference of the cause (3), the main container body 1 forms oil gas, and the pressure balance assembly 4 is used to communicate the main container body 1, the metering neck 2 and the oil inlet part 21, so as to realize controllable adjustment and avoid secondary floating foam.
[0064] Therefore, the advantage of the technical scheme is that the floating foam and foam problem caused by adding the test oil in the test metering operation can be effectively reduced, compared with the traditional metering container, the measured oil liquid level can be quickly stabilized, the floating foam is less, and the reading is easy to read.

[0067] In a specific embodiment, please refer to Figure 2 As shown in the figure, it also includes: a liquid level discharge pipe 204, the first end of the liquid level discharge pipe 204 is connected to the bottom of the liquid level tube body 201, and the second end of the liquid level discharge pipe 204 communicates with the container bucket body 101; a liquid level discharge valve 205 is arranged on the liquid level discharge pipe 204.
