DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0027] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0028] like Figure 2As shown, the thermos cup testing device described in the present application includes a hot air blower 1, a circulating air duct 2, a control valve 3 and a test chassis 4, wherein the hot air blower 1 is used to provide hot air for heating the inside of the thermos cup to be tested, and includes an air outlet 10 for blowing out the hot air and an air inlet 12 for sucking in the hot air, and the circulating air duct 2 includes a first air duct 20 and a second air duct 22, the first air duct 20 is used to receive the hot air blown out of the air outlet 10, and the second air duct 22 is used to provide the circulated hot air to the air inlet 12, so that the hot air blower 1 can heat the hot air again with less heat, thereby realizing the recycling of the hot air.

[0029] An air outlet 40 for blowing hot air into the thermos cup to be tested and an air inlet 42 for sucking hot air from the thermos cup to be tested are provided on the test chassis 4. To control the blowing of hot air into the thermos cup, the first air duct 20 and the second air duct 22 are both connected to the control valve 3, and are respectively connected to the air outlet 40 and the air inlet 42 through the control valve 3, so that the control valve 3 can control the first air duct 20 and the second air duct 22 to be connected to each other or the first air duct 20 to be connected to the air outlet 40 and the second air duct 22 to be connected to the air inlet 42.

[0030] The control valve 3 can be Figure 2 As shown, there are two independent pipes connected to the air outlet 40 and the air inlet 42 respectively, and the opening and closing of the air outlet 40 and the air inlet 42 are controlled by switching one end of the independent pipe. It can also be set to be directly fixed to the air outlet 40 and the air inlet 42 without passing through the pipe, as long as the opening and closing of the air outlet 40 and the air inlet 42 can be controlled separately.

[0031] When there is no need to blow hot air into the thermos cup, the control valve 3 closes the air outlet 40 and the air inlet 42, and connects the first air duct 20 and the second air duct 22. At this time, the hot air blown out from the air outlet 10 directly enters the second air duct 22 through the first air duct 20, and flows back to the air inlet 12; when it is necessary to blow hot air into the thermos cup, the control valve 3 closes the first air duct 20 and the second air duct 22 to each other, and connects them to the first air outlet 40 and the second air outlet 42 respectively. In this way, the hot air blown out from the air outlet 10 flows through the first air duct 20, enters the interior of the thermos cup through the air outlet 40, flows out of the thermos cup through the air inlet 42, and returns to the air inlet 12 through the second air duct 22.

[0032] The present application adopts a circulating air duct formed by a first air duct and a second air duct controlled by a control valve to connect the air outlet and the air inlet of the hot air blower, so that the thermos cup testing device provided by the present application does not need to turn off the hot air blower during operation. The hot air at the air outlet flows back to the air inlet under the control of the control valve, avoiding energy loss and fan damage caused by turning on and off the hot air blower.

[0033] The control valve 3 described in this embodiment may be a solenoid valve, so that the air outlet and air inlet can be controlled more accurately through the control circuit.

[0034] like Figure 2 As shown, in order to improve the test efficiency, the test chassis 4 and the corresponding control valves 3 in the embodiment of the present application are set to be multiple, and the hot air blower 1 is interconnected with the multiple control valves 3 and the air outlet 40 and the air inlet 42. This can improve the utilization rate of the hot air blower 1, and at the same time provide detection for multiple thermos cups, thereby improving the test efficiency.

[0035] In order to test the heat preservation performance of the thermos cup, the thermos cup testing device provided in the embodiment of the present application further includes a clamping assembly 5, which is used to cooperate with the test chassis 4 to clamp the thermos cup to be tested to form a closed space, so that the heat preservation performance of the thermos cup can be tested by heating the closed space. In order to achieve the function of clamping the thermos cup, the clamping assembly 5 is arranged relative to the test chassis 4 and can reciprocate in the direction of the test chassis 4, such as Figure 1 The clamping assembly 5 shown is arranged above the test chassis 4 and can reciprocate in the vertical direction. When a thermos cup is placed on the test chassis 4, the clamping assembly 5 can move downward and clamp the thermos cup. The clamping assembly 5 can be as follows: Figure 1 The figure includes a cylinder 50 and a clamping arm 52. The clamping arm 52 and the thermocouple 6 are both connected to the cylinder 50 and can be driven by the cylinder 50. In order to enable the thermocouple 6 to contact the thermos cup to be tested when the clamping arm 52 is extended, the thermocouple 6 is arranged on the side where the clamping arm 52 and the thermos cup to be tested are in contact with each other.

[0036] To ensure that the thermal insulation performance test is carried out smoothly, the air outlet 40 and the air inlet 42 are both arranged in a closed space. At the same time, in order to improve the temperature measurement accuracy during the thermal insulation cup test, the thermal insulation cup test device provided in this embodiment also includes a thermocouple 6. The thermocouple 6 can be as follows: Figure 1 The setting shown is integrated with the clamping component 5, and can also be connected to the clamping component 5 through components such as a connecting part, and can follow the movement of the clamping component 5 to fit or separate from the outer wall of the thermos cup to be tested, so that the thermal insulation performance of the thermos cup can be reflected by testing the temperature change of the outer wall of the thermos cup to be tested before and after the hot air is blown into it.

[0037] In order to automate the thermos cup testing process to a certain extent, in the present embodiment, a photoelectric sensing module 7 is also included. The photoelectric sensing module 7 is arranged on the test chassis 4, so that it can sense whether there is a thermos cup to be tested placed on the test chassis 4. When the thermos cup to be tested is placed on the test chassis 4 and the cup mouth of the thermos cup to be tested covers the air outlet 40 and the air inlet 42, the clamping assembly 5 receives a control signal and starts to clamp the thermos cup to be tested and the test chassis 4, and starts the test process.

[0038] In order to make the test thermos cup and the test chassis 4 fit better, the test chassis 4 has a circle of abutment ring 44 made of elastic material. The abutment ring 44 can fit the cup mouth of the thermos cup to be tested and abut each other to form an enclosed space. The abutment ring 44 can be made of rubber or other elastic materials such as elastic plastic.

[0039] During the thermos cup test, it is necessary to control the operation of the clamping assembly 5, the control valve 3 and other structures according to a certain procedure, and record the data obtained by the thermocouple 6 for statistical comparison, etc. Therefore, in this embodiment, the thermos cup test device also includes a control processing module electrically connected to the clamping assembly 5 and the control valve 3 and a data recording module electrically connected to the thermocouple 6. The control processing module and the data recording module can be two control modules arranged on the same circuit board, or can be two independent electronic components, etc., which will not be repeated here.

[0040] The present application also provides a method for testing the heat preservation performance of a thermos cup, using the above-mentioned thermos cup testing device with a thermocouple, comprising the following steps:

[0041] S1: The mouth of the thermos cup to be tested is fitted to the test chassis, and the photoelectric sensing module senses that the mouth of the thermos cup to be tested covers the air outlet and the air inlet;

[0042] S2: The pressing assembly presses and fixes the thermos cup to be tested and the test chassis to form a closed space, and the thermocouple follows the movement of the pressing assembly to fit the outer wall of the thermos cup to be tested.

[0043] The present application adopts a circulating air duct formed by a first air duct and a second air duct controlled by a control valve to connect the air outlet and the air inlet of the hot air blower, so that the thermos cup testing device provided by the present application does not need to turn off the hot air blower during operation. The hot air at the air outlet flows back to the air inlet under the control of the control valve, avoiding energy loss and fan damage caused by turning on and off the hot air blower.

[0044] The above embodiments of the present application focus on describing the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

[0045] The above is only the embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
