The sensor 4 is electrically connected to the pressure adjusting mechanism 3, and the pressure adjusting mechanism 3 reduces the air pressure of the tank 1 in response to a signal detected by the sensor 4 that the cover 2 is in the closed state. In the present embodiment, the pressure adjusting mechanism 3 may reduce the air pressure in the tank 1 at a different timing from the timing of boiling the cleaning liquid at a low pressure, for example, the air pressure in the tank 1 may be reduced immediately after the sensor 4 detects that the lid 2 is closed, the lid 1 is closed, the normal air pressure is returned to the normal air pressure, and then the air pressure is reduced according to the control to realize the low pressure boiling. After the air pressure in the tank body 1 is reduced, the air pressure in the tank body 1 is lower than the air pressure outside the tank body 1, the pressure formed by the air pressure difference between the inside and outside of the tank body 1 enables the cover body 2 to be closer to the tank body 1, the cover body 2 is more tightly matched with the tank body 1, and the tightness of the cleaning device is improved. From this avoided cell body 1 outside air to get into in the cell body 1 through the gap between lid 2 and the cell body 1, guaranteed the washing of cell body 1, vacuum drying in-process vacuum, and then be favorable to guaranteeing belt cleaning device's cleaning performance and vacuum drying effect.

Second embodiment

Fig. 4 is a schematic block diagram of a cleaning apparatus according to a second embodiment of the present utility model. As shown in fig. 4, the present embodiment provides a cleaning device.

In the present embodiment, the pressure adjusting mechanism 3 includes a vacuum pump 17, and the vacuum pump 17 is used to control the vacuum degree of the tank 1. When the vacuum degree in the tank 1 increases, the air pressure on the liquid surface decreases. If the gas pressure on the liquid surface is lower than the saturated vapor pressure of the liquid at this time, the phenomenon of low-pressure boiling of the liquid occurs.

Further, the cleaning device also comprises a fan 12. In the present embodiment, the fan 12 is provided inside the tank 1. Evaporation of moisture requires the absorption of a large amount of heat, i.e., latent heat. As the moisture evaporates, the humidity of the surrounding air increases, which gradually slows down the rate of moisture evaporation. Air around the moisture can be taken away by blowing air through the fan 12, so that the moisture in the air is diffused more quickly, the humidity of the surrounding air is reduced, and the evaporation speed of the moisture is increased. Meanwhile, the wind can also take away latent heat required by water evaporation, so that liquid water is more easily converted into water vapor.

The tank body 1 is provided with the air outlet 13, improves the ventilation of the tank body 1, and vapor is discharged out of the tank body 1 through the air outlet 13, so that the accumulation of vapor in the tank body 1 in the air supply drying process is reduced or even avoided to prevent drying.

The cleaning device has an air-blowing drying mode and a vacuum drying mode, and a user can select a specific drying mode according to the type, structure, and the like of the object to be cleaned 10 to dry the object to be cleaned 10. This can improve the drying efficiency and reduce the drying time. Or a mixed drying mode, namely an air supply drying mode and a vacuum drying mode are alternately adopted, so that the advantages of air supply drying and vacuum drying can be considered. In addition, the cleaning device may also set an automatic drying mode, that is, the object 10 to be cleaned is identified by the sensor 4, and then an appropriate drying mode is automatically selected.

Specifically, the object 10 to be cleaned having good ventilation is suitable for drying by blowing, and the object 10 to be cleaned having relatively close structure such as a large number of corners or parts and a tubular object is suitable for drying by vacuum. For example, in the corners or the inside of the object 10 to be cleaned, the air blowing and drying efficiency is not good because the air is hard to blow. Vacuum drying is suitable for drying the parts where these wind is difficult to blow, and thus drying them sufficiently.

In the present embodiment, the fan 12 is provided on the side of the lid 2 facing the tank 1, and the fan 12 is provided on the lid 2 so as to directly blow air to the cleaning object 10 in the tank 1. The closer the fan 12 of the same power is to the object 10 to be cleaned, the faster the air flow on the surface of the object 10 to be cleaned. The faster the air flow speed is, the higher the evaporation speed can be, thereby improving the air supply drying efficiency.

The motor 14 for driving the fan 12 is disposed at one side of the cover 2 far from the tank 1, which can avoid the obstruction of the motor 14 to the wind blown out by the fan 12, and is beneficial to ensuring the air supply efficiency of the fan 12.

In the present embodiment, the fan 12 is a centrifugal fan. Centrifugal fans are capable of producing a larger air flow, and therefore, they can provide a greater amount of air. The centrifugal fan impeller generates less noise than the conventional fan 12 when rotated at a high speed. Centrifugal fans, because of their relatively small diameter impeller, are capable of generating a more stable airflow due to their relatively high rotational speeds, reducing vibration and shock. The air blown out by the centrifugal fan is quicker and more stable, and is favorable for guaranteeing the speed and stability of air supply drying.

In other embodiments of the present utility model, the fan 12 is not limited to a centrifugal fan, but may be other types of fans 12, such as a rotary fan, etc.

Further, the cleaning device further comprises a heater 15, and the heater 15 is arranged at the bottom of the tank body 1. The heater 15 can heat the air during the air-blowing drying, and the hot air drying can increase the drying speed by heating the air, so that the drying time can be reduced as compared with the case where the heater 15 is not provided.

The heater 15 has a plurality of fins 16, and the fins 16 can effectively increase the heat radiation area of the heater 15, thereby increasing the heat radiation speed, so that the heater 15 can transfer heat to the surrounding environment more quickly. This can raise the temperature of the air in the tank 1 more quickly, thereby contributing to promotion of drying and further reduction of drying time.

Those skilled in the art will appreciate that the specific features of the various embodiments may be adaptively split or combined. Such splitting or combining of specific technical features does not cause the technical solution to deviate from the principle of the present utility model, and therefore, the technical solution after splitting or combining falls within the protection scope of the present utility model. In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
