Abstract: A mosquito trapping device includes a body, a mosquito storage box, a fan, and a net cover assembly, where the net cover assembly is arranged on an upper end portion of the body and forms a first accommodation space with the body, and the mosquito storage box is mounted on the body; the net cover assembly includes a first net cover, a second net cover, and a third net cover, where the first net cover is provided with a first air outlet portion in communication with the first accommodation space, and the third net cover is provided with a first air inlet portion matching the fan; the mosquito storage box is provided with a second air inlet portion positioned right below the fan and a third air outlet portion in communication with the first accommodation space.

Abstract: The present invention provides a mosquito trapping device, which comprises a carbon dioxide generating module, a temperature control module, a humidity control module, and a mosquito-killing module. The carbon dioxide generating module comprises a container A and a container B, a solution in the container A reacts with a solution in the container B to generate carbon dioxide; the temperature control module controls a temperature of the mosquito trapping device to be between 38° C. and 45° C.; the humidity control module controls humidity of the mosquito trapping device to be between 50% and 80%; the mosquito-killing module generates a guiding wind having a wind speed of 0.7 m/s to 15 m/s. The present invention has a good mosquito-attracting effect and a desirable mosquito-killing ability.

Abstract: A model of vessel installation and placement includes a shelf and a vessel installed under the shelf. There is at least one absorbing board equipped respectively on the shelf and arranged alternately. Absorbed boards attached to the absorbing boards are equipped to the bottom or the open of the vessel. Absorbing boards are equipped alternately to the shelf. And absorbed boards are equipped to the bottom or the open of the vessel and are attached to absorbing boards. Hence, when in use, absorbing boards on the shelf are attached to absorbed boards at the bottom or the open of the vessel, which enables that the bottom of the vessel faces up and the open of the vessel points down and is set under the shelf. This method can avoid accumulation of dust and moisture when the vessel is unused for a period of time and can keep clean of the internal vessel, so as to avoid that support frame or internal vessel is accumulated with moisture and dust and keep the vessel clean.
