Specific implementation mode

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-5 , the present invention provides a technical solution: a frozen machine for aquatic products, including a box body 4, a freezer 7 installed inside the box body 4, and a refrigeration mechanism 9 surrounding the periphery of the freezer 7. The refrigeration mechanism 9 includes an evaporator 901, a compressor 902, a condenser 903, and an expansion valve 904. The evaporator 901 is connected to both sides and the bottom of the freezer 7. The compressor 902 is connected to the evaporator 901 and the condenser 903 respectively through pipes. The expansion valve 904 is connected to the evaporator 901 and the condenser 903 respectively through pipes; several air inlet mechanisms 5 are installed on both sides of the box body 4, and a negative pressure fan exhaust 10 is installed between both sides of the freezer 7 and the end cover 1. Among them, the negative pressure fan exhaust 10 is composed of a plurality of negative pressure fans and partitions. Several detachable air ducts 8 are installed on the top of the freezer 7, and several ventilation windows 11 are opened on the side of the freezer 7. The several ventilation windows 11 correspond to the several air ducts 8 one by one.

[0027] Based on the above structure settings, this aquatic product freezer is composed of a box body 4, a freezer box 7 installed inside the box body 4, and a freezing mechanism 9 surrounding the outer periphery of the freezer box 7. Among them, the freezer box 7 is used for storing aquatic products, the freezing mechanism 9 is used for freezing the aquatic products inside the freezer box 7, and the box body 4 is used for wrapping and protecting the freezer box 7 and the freezing mechanism 9. Specifically, during the working process, after putting the aquatic products into the freezer box 7, the freezing mechanism 9 is started, and the freezing of the aquatic products in the freezer box 7 is realized through the mutual cooperation among the evaporator 901, the compressor 902, the condenser 903, and the expansion valve 904. When it is necessary to take out or store from the freezer box 7 during the freezing process, after opening the end cover 1, the negative pressure exhaust fan 10 is started, and the air inlet mechanism 5 is opened. After opening, under the guidance of the negative pressure exhaust fan 10, the gas around the device enters the inside of the box body 4 through the air inlet mechanism 5, is cooled by the evaporator 901 and then enters the inside of the air duct 8 through the ventilation window 11 and is discharged. Thus, a cold air wall barrier is formed at the opening of the freezer box 7 by using the air duct 8 to slow down the loss of the temperature inside the freezer box 7. This aquatic product freezer can form a low-temperature air wall at the opening of the freezer box 7 to slow down the loss of the temperature inside the freezer box 7 through the mutual cooperation of the air inlet mechanism 5, the air duct 8, and the negative pressure exhaust fan 10. By using the gaps between the air ducts 8 or removing the air duct 8 from the freezer box 7, the addition and taking of aquatic products into the freezer box 7 can be realized.

[0028] Furthermore, the air inlet mechanism 5 includes a solenoid valve 501 and a filter 502. The filter 502 is installed on both sides of the box body 4, and the solenoid valve 501 is assembled on the side of the filter 502 away from the box body 4. Among them, the solenoid valve 501 is in a normally closed state. Specifically, when in use, after opening the solenoid valve 501, the gas outside the device enters the inside of the filter 502 through the solenoid valve 501.

[0029] Furthermore, the air inlet mechanism 5 further includes a filter plate 503. A detachable filter plate 503 is installed inside the filter 502, and air inlet holes corresponding to the positions of a plurality of air inlet mechanisms 5 are opened on the side surface of the box body 4. Among them, the filter plate 503 is used for filtering the gas entering the inside of the box body 4, and the air inlet holes are used for guiding the filtered water to the inside of the box body 4.

[0030] Furthermore, a plurality of air outlet windows 12 are opened at equal intervals at both ends of the air duct 8, and a card slot adapted to the air duct 8 is opened at the top of the freezer box 7. Among them, the air outlet windows 12 are located on both sides of the air duct 8. Specifically, the gas in the air duct 8 is discharged by using the air outlet windows 12, and the disassembly and assembly of the air duct 8 can be facilitated through the card slot.

[0031] Further, an end cover 1 is rotatably connected to the side surface of the box body 4 through a hinge, and a handle 2 is installed on the side surface of the end cover 1. Specifically, the end cover 1 can be used to seal and protect the box body 4, and the handle 2 can facilitate the user to flip the end cover 1 for use.

[0032] Further, an inner groove is formed on the side of the end cover 1 close to the freezer 7, and a plurality of activated carbon boxes 3 are equally spaced inside the inner groove. Among them, the activated carbon box 3 contains activated carbon material. Specifically, by using the activated carbon box 3, the peculiar smell in the freezer 7 can be adsorbed and treated, improving the quality of the gas in the freezer 7.

[0033] Further, the internal space of the box body 4 is divided into an upper inner cavity and a lower inner cavity. The freezer 7 and the evaporator 901 are located in the upper inner cavity, and the compressor 902, the condenser 903 and the expansion valve 904 are located in the lower inner cavity. Specifically, by using the upper and lower parts to isolate the equipment, the equipment can be effectively isolated and protected during use.

[0034] Further, universal wheels 6 are fixedly connected to the four corners of the bottom of the box body 4, and a label is attached to the front end of the box body 4. Specifically, the universal wheels 6 can facilitate the user to move the position of the device, and the label can introduce the device in the form of pictures and texts.
