[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] Example:

[0025] See also Figure 1-4 The utility model provides a technical solution: an automatic cleaning device for a mass spectrometer target plate, comprising:

[0026] The base 2 is hollow and open at the top, and a support cavity 6 is formed by extending outward from the inner upper side of the base 2; Figure 4 As shown in the figure, the support cavity 6 is a space with a wider lateral width at the upper end of the base 2, and a step is formed between the support cavity 6 and the lower side of the inner part of the base 2, through which the edge of the target plate can be supported.

[0027] Ultrasonic cleaning devices 7 are embedded in two diagonal portions on the lower inner side of the base 2, and drying outlets 8 are embedded in positions corresponding to the other two corners on the lower inner side of the base 2 in the support cavity 6; the two ultrasonic cleaning devices 7 and the two drying outlets 8 are distributed at four corners on the base 2. Since the ultrasonic cleaning device 7 needs to be immersed in water, the ultrasonic cleaning device 7 is placed in the lower inner space of the base 2, and the drying outlet 8 cannot contact water. The drying outlet 8 is placed in the support cavity 6, so that it will not be corroded by internal water and can be blown and dried at a close distance to the target plate.

[0028] Both ends of the base 2 are provided with storage chambers 9, and a hot air blower 10 connected to the drying outlet 8 through a pipeline is provided in the storage chamber 9. A wire 12 for supplying power to the ultrasonic cleaning device 7 and the hot air blower 10 is provided on the base 2;

[0029] A top cover 1 is disposed on the upper portion of the base 2 , and a sterilization device is disposed at an opening of the lower surface of the top cover 1 facing the base 2 .

[0030] Preferably, a drain pipe 11 communicating with the inner cavity of the base 2 is provided at the bottom of the base 2, and a control valve is installed on the pipeline of the drain pipe 11. Through the cooperation of the drain pipe 11 and the control valve, the cleaning water in the base 2 can be discharged.

[0031] Preferably, the sterilization device comprises an ultraviolet sterilization lamp 4 arranged on the lower surface of the top cover 1 and a control switch 3 arranged on the upper surface of the top cover 1 , and the control switch 3 and the ultraviolet sterilization lamp 4 are electrically connected.

[0032] Ultraviolet disinfection is the use of ultraviolet rays of appropriate wavelengths to destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of microorganisms, causing growth cell death and (or) regenerative cell death, achieving the effect of sterilization and disinfection. Ultraviolet disinfection technology is based on modern epidemiology, medicine and photodynamics, using specially designed high-efficiency, high-intensity and long-life UVC band ultraviolet light to irradiate flowing water, directly killing various bacteria, viruses, parasites, algae and other pathogens in the water.

[0033] Preferably, the lower surface of the top cover 1 is provided with an embedded frame 5 that can be inserted into the support cavity 6 and closes the upper side of the support cavity 6, and the ultraviolet germicidal lamp 4 is located inside the embedded frame 5. The cooperation between the embedded frame 5 and the support cavity 6 makes it difficult for the top cover 1 and the base 2 to shake relative to each other, and the embedded frame 5 can prevent water in the base 2 from splashing to the outside, and when the top cover 1 is placed on the desktop, the ultraviolet germicidal lamp 4 will not directly contact the desktop, so as to protect the ultraviolet germicidal lamp 4.

[0034] Preferably, support legs are provided at the four corners of the lower surface of the base 2. The base 2 can be supported by the support legs to prevent the drain pipe 11 from touching the ground.

[0035] Working principle: When in use, the target plate is placed in the support cavity 6, and the support cavity 6 is pre-set to match the size of the target plate according to the size of the target plate, so that there is a certain gap between the edge of the support cavity 6 and the target plate, which is convenient for hot air to dry the target plate.

[0036] The top cover 1 is placed on the base 2 so that the embedding frame 5 is embedded in the supporting cavity 6 and does not contact the target plate.

[0037] The base 2 is filled with water that overflows the target plate, and the water level is not higher than the position of the drying outlet 8. The drying outlet 8 is set to an inclined shape to prevent water from entering the drying outlet 8 and backflowing into the hot air blower 10. The ultrasonic cleaning device 7 works to clean the target plate, and then the water in the base 2 is discharged. The hot air blower 10 blows hot air into the base 2 through the drying outlet 8 to dry the target plate. In this process, the ultraviolet light generated by the ultraviolet germicidal lamp 4 sterilizes and disinfects the target plate. The target plates are generally cleaned and disinfected one at a time to avoid stacking of target plates, so as to avoid poor disinfection and sterilization effect of the target plate on the lower side.
