FIG. 2 is a partial enlarged view of A in FIG. 1 .

Detailed ways:

An embodiment, as shown in Figures 1 to 2, a detachable urine collection device, comprising a detachably connected funnel body 1 and a urine collection bottle 2, the funnel body 1 comprising an integrally formed wide-mouth conical disc 11 and the column body 12, the column body 12 is formed with a stepped through hole 121, and the inner wall of the small hole at the lower end of the stepped through hole 121 is formed with an inner wall thread 122; the urine collection bottle 2 includes an integrally formed bottle body 21 and a bottle mouth 22, An outer wall thread 221 is formed on the outer wall of the bottle mouth 22, and the outer wall thread 221 is screwed into the inner wall thread 122; the inner wall of the bottle mouth 22 is sleeved and fixed with a first rubber stopper 3, and the first rubber stopper 3 The needle tube 4 is sleeved, the upper end of the needle tube 4 is inserted into the second rubber plug 5, the second rubber plug 5 is fixed in the upper end large hole of the step through hole 121, and the upper end surface of the needle tube 4 is higher than the second rubber plug 5. The upper end face of the rubber plug 5 and the lower end face of the needle tube 4 are lower than the lower end face of the first rubber plug head 3; 401.

Furthermore, an inclined branch pipe 23 is fixed on the outer wall of the bottle body 21, the branch pipe 23 is formed with a through hole 231 which communicates with the inner cavity of the bottle body 21, and the upper port of the through hole 231 is sleeved with a plug. The upper end face of the head 24 and the plug head 24 is lower than the lower end face of the cylinder 12 .

Furthermore, the bottle mouth 22 is formed with a vertical hole 222 that communicates with the inner cavity of the bottle body 21, and the outer wall of the bottle mouth 22 is formed with a horizontal hole 223 that communicates with the vertical hole 222. A ventilation groove 123 is formed on the outer wall, and the ventilation groove 123 communicates with the transverse hole 223 .

More specifically, the vertical hole 212 is provided with a sponge strip 6 , the outer wall of the sponge strip 6 is pressed against the inner wall of the vertical hole 222 , and the position of the sponge strip 6 is lower than the horizontal hole 223 .

Furthermore, the bottle body 21 is made of transparent material, and a scale bar 211 is formed on the outer wall of the bottle body 21 .

Furthermore, the magnitude of the static friction force between the first rubber stopper 3 and the needle tube 4 is greater than the magnitude of the static friction force between the second rubber stopper 5 and the needle tube 4 .

Furthermore, a handle 13 is provided between the wide-mouthed conical disc 11 and the cylinder 12 .

Working principle: First, hold the handle 13 by hand, and sprinkle the urine into the wide-mouth conical disc 11, and the urine in the wide-mouth conical disc 11 flows into the urine collection bottle 2 through the liquid hole 401 of the needle tube 4; second, Rotate the urine collection bottle 2, so that the outer wall thread of the bottle mouth 22 is separated from the inner wall thread 122 of the cylinder 12, so that the funnel body 1 and the urine collection bottle 2 are separated. Since the static friction force between the first rubber stopper 3 and the needle tube 4 is greater than The size of the static friction between the second rubber stopper 5 and the needle tube 4, so the needle tube 4 is separated from the second rubber stopper 5 along with the urine collection bottle 2, and the needle tube 4 is separated from the second rubber stopper 5 at the same time. The head 5 closes the hole through which the needle tube 4 is inserted, thereby preventing the urine in the inner cavity of the wide-mouth conical disc 11 from dripping down; At the same time of the first rubber stopper 3, the first rubber stopper 3 closes the hole through which the needle tube 4 is inserted, thereby preventing the urine in the urine collection bottle 2 from swinging out to the outside; fourth, the bottle mouth 22 is provided with vertical holes 222, The horizontal hole 223 and the ventilation groove 123 of the cylinder 12 can ensure that the pressure of the inner cavity of the bottle body 21 is balanced with the atmospheric pressure, thereby ensuring that the urine in the wide-mouth conical disc 11 flows smoothly into the urine collection bottle 2; fifth, the vertical hole 222 is provided with a sponge strip 6, which can effectively prevent the urine in the urine collection bottle 2 from overflowing to the outside through the vertical hole 222 and the horizontal hole 223 during the transfer of the urine collection bottle 2; When the urine is poured out, just remove the plug 24 and pour it out from the through hole 231 of the branch pipe 23, which is convenient and quick.
