Decorative product capable of feeding micro animals

[0022] Example 1

[0023] This embodiment is designed as a decorative pendant for keeping miniature pets (see figure 1 , 2 ), the shell 3 is a spherical body with a diameter of 4cm, the diameter of the port 31 is 0.6mm, with a hanging ring, the diameter of the threaded sealing plug 1 is Φ=0.6mm, which can be disassembled at will, the hydrophobic material The tubular membrane fiber 2 is made of polyethylene material , the shell 3 is made of transparent plastic; the hydrophobic material tubular membrane assembly 6 is located in the through hole 5 in the middle of the plastic shell 3, and the hydrophobic material tubular membrane fiber 2 is in direct contact with the water in the inner cavity of the shell 3, and both ends pass through the tube The sealing end of the tubular membrane module 6 is in contact with the housing 3, and the gap is sealed with water sealing material, so that the tubular membrane module 6 and the housing 3 form a water-tight structure (see figure 1 ). Then

[0025] Example 2

[0026] The shell 3 of the second embodiment is a cylinder, the diameter of the bottom surface is 6cm, and the shape adopts a large aspect ratio, which is a slender cylindrical shape. Two thirds and two thirds of the length are respectively installed. The tubular membrane module 6 is installed in the same or vertical direction. The shell is made of plexiglass material. The tubular membrane fiber 2 is made of polypropylene material with a porosity of 50% and a diameter of d=0.3. The rest are the same as in Example 1.

[0027] The minimum packing number n of the tubular membrane fibers 2 is estimated according to formula (1) to obtain n=7.5, that is, at least 8 tubular membrane fibers 2 are selected, and the fibers are divided into two groups and cast into the tubular membrane module 2 .

[0028] Example 3

[0029] This implementation designs a decoration product. The shape is spherical, the diameter of the shell 3 is 20cm, the inner diameter of the port is 3mm, and the diameter of the assembled threaded sealing plug 1 is Φ=3mm, which can be disassembled at will for regular water changes. The difference from the aforementioned hanging ornaments is that there is no hanging ring on the inner plug of the ornamental ornament, but a hanging seat matching the outer shell is added to place decorative products.

[0030] The length of the tubular membrane fiber of the hydrophobic material is 15 cm, the porosity is selected as 40%, and the diameter d of the membrane fiber is 0.3 cm. According to the calculation method of formula (1), at least the number n of filling pieces calculated is 42 pieces, and they are poured, and the obtained tubular membrane module 2 of hydrophobic material is put into the through hole 5 of the casing 3, and the through hole 5 is opened at a dista
