[0014] In order to adapt to cleaning machines of different heights, a lifting device for adjusting the height of the cabinet is also included, and the bottom side of the cabinet has a first opening.

[0015] In order to adjust the height of the cabinet, the edge of the bottom of the cabinet is bent outward and extended to form a mounting plate;

[0016] The lifting device comprises at least three groups of lifting wheel assemblies arranged at intervals along the length direction of the mounting plate, each lifting wheel assembly comprising

[0017] A screw rod, arranged vertically and threadedly connected to the mounting plate;

[0018] A mounting base connected to the bottom end of the screw rod; and

Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0028] like Figure 1 The figure shows a preferred embodiment of the sealing evaluation test cabinet for a cleaning machine of the present invention. The sealing evaluation test cabinet for a cleaning machine comprises a cabinet body 1, a tank body 2, a lifting wheel assembly 3 and a water receiving box 4.

[0029] The cabinet 1 has a cavity 11 for accommodating the cleaning machine inside; the bottom side of the cabinet 1 has a first opening 12; the front side of the cabinet 1 has a second opening 13 for the cleaning machine to pass through and enter and exit the cavity 11; the edge of the bottom of the cabinet 1 is bent outward and extended to form a mounting plate 14; four hooks 15 are installed on the side wall of the cabinet 1, which are spaced and equidistantly arranged in the height direction; a make way opening 16 is opened on the rear side wall of the cabinet 1 to make way for the water inlet pipe and drain pipe of the cleaning machine.

[0030] The opening of the trough body 2 faces upward, and the trough body 2 is installed on the top of the cabinet body 1, and the bottom wall of the trough body 2 is in contact with the top wall of the cabinet body 1 for heat conduction connection. The above-mentioned trough body 2 is used to accommodate ice water and can be used as a cooling device to cool the cabinet body 1, so that the steam leaked from the cleaning machine condenses after contacting the cabinet body 1 and forms water droplets on the inner wall of the cabinet body 1. In addition, the entire cabinet body 1 is made of transparent material so that the user can observe the water droplets formed on the cabinet body 1; the side of the trough body 2 has a drain port 21, and the drain port 21 is plugged with a rubber plug during testing. After the test, the ice water can be directly discharged through the drain port 21.

[0031] There are four sets of lifting wheel assemblies 3, which are respectively installed at the four corners of the bottom of the cabinet 1. Each lifting wheel assembly 3 includes a screw rod 31, a mounting seat 32 and a pulley 33. Specifically, the screw rod 31 is arranged vertically and threadedly connected to the mounting plate 14; the mounting seat 32 is connected to the bottom end of the screw rod 31; and the pulley 33 is rotatably installed at the bottom of the mounting seat 32. In this way, by rotating the screw rod 31 of each lifting wheel assembly 3, the height of the cabinet 1 can be adjusted, so as to adapt to cleaning machines of different heights.

[0032] The water receiving box 4 is installed at the front side of the cabinet 1 to receive water drops from the exhaust pipe outlet of the cleaning machine. Specifically, the side of the water receiving box 4 has a hanging bracket 41, and the hanging bracket 41 is provided with two hanging holes 411 arranged at intervals, which are used for two adjacent hooks 15 to be clamped. In this way, by hanging the hanging bracket 41 on two hooks 15 at different heights, the height of the water receiving box 4 can be adjusted to adapt to different models of cleaning machines (with different exhaust pipe heights).

[0033] The working principle of this embodiment is as follows: during the test, the cleaning machine is placed in the cavity 11 of the cabinet 1 through the second opening 13, with the operating surface facing outward, and ice water is poured into the tank 2. When water vapor leaks during the cleaning machine test, the leaked steam immediately condenses into tiny water droplets after hitting the cold cabinet 1, which can be directly observed with the naked eye. The location and amount of steam leakage of the cleaning machine can be determined based on the location and number of condensed water droplets, thereby accurately evaluating the sealing performance of the cleaning machine. In addition, the amount of water received by the water receiving box 4 can also be used to understand the dripping condition of the exhaust pipe when the cleaning machine is drying and exhausting.
