[0002] Ovulation refers to the process of releasing a mature egg from the ovary. The physiological cycle of women can be monitored by monitoring ovulation. A portable ovulation detector is an ovulation test device that allows women to detect whether they are in their fertile or non-fertile period anytime and anywhere to effectively grasp the probability of pregnancy. It is a compact and portable ovulation test device that is properly arranged and concentrated with necessary components.

[0003] Generally, the test card is inserted into the detector, and then placed vertically in the urine for testing for 15 seconds. The detector is then laid flat and waited for ten minutes.

A buckle push plate is provided on the inner side of the connecting compartment 4. A test card 5 is connected to the inside of the connecting compartment 4 through the buckle push plate. A sample addition hole 6 is provided at one end of the test card 5. A locking hole 7 is provided at one end of the test card 5 away from the sample addition hole 6. A filling hole 808 is provided at the bottom of the detector body 1. A touch detection component is installed at one end of the detector body 1 away from the connecting compartment 4.

[0030] In this embodiment, when installing the test card 5, first insert the end of the test card 5 with the locking hole 7 into the interior of the connecting bin 4. At this time, the test card 5 is fixed by the buckle push plate inside the connecting bin 4, and then the test card 5 is vertically placed in the urine for testing for fifteen seconds. Then the detector body 1 is laid flat. After the detector body 1 is placed, the detector body 1 is horizontally detected by the touch detection part. If the detector body 1 is in a tilted state, a warning is given by the touch detection part at this time to prevent the detector body 1 from flowing urine into the interior of the connecting bin 4 during the waiting process. After laying the detector body 1 flat, wait for ten minutes, and determine the result by the hormone measurement value. The test result will be displayed on the display screen 2. Then, take the detector body 1 and hold the test card 5 vertically downward. Then, the test card 5 is separated from the connecting bin 4 by operating the buckle push plate, and there is no need for the staff to manually take the test card 5.

[0031] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The buckle push plate includes a side connecting warehouse 801 installed on both sides of the connecting warehouse 4. The connecting warehouse 4 is internally slidably connected to two card-positioning sliders 810. The two card-positioning sliders 810 are symmetrically arranged along the transverse central axis of the connecting warehouse 4. The side of the card-positioning slider 810 away from the insertion hole 831 is an inclined structure. A connecting plate 812 is installed on the top of the card-positioning slider 810. The two card-positioning sliders 810 are connected through the connecting plate 812. The connecting plate 812 is provided with a first return spring 811 connected to the inner wall of the connecting warehouse 4. The inside of the side connecting warehouse 801 is plugged with a locking pin 814 extending to the inner side of the connecting warehouse 4, and a blocking plate 813 is arranged on the outer side of the locking pin 814. The blocking plate 813 is provided with a second return spring 816 connected to the inner wall of the connecting bin 4, and the interior of the side connecting bin 801 is provided with a movable plug rod 803 extending to the outside of the side connecting bin 801, and one end of the movable plug rod 803 is rotatably connected to an oblique rotating plate 815 located on the inner side of the side connecting bin 801 through a rotating shaft, and the end of the oblique rotating plate 815 away from the movable plug rod 803 is also rotatably connected to a locking pin 814 through a rotating shaft, and a locking hole 817 is provided on the locking slider 810, and one end of the movable plug rod 803 is installed with a pressure plate 806 located at the end of the detector body 1 away from the connecting bin 4, and a telescopic rod 804 is connected between the pressure plate 806 and the detector body 1.

At this time, the locking hole 7 is aligned with the locking hole 817, and the test card 5 is pushed to move the test card 5 toward the connecting chamber 4. At this time, the end of the test card 5 close to the locking hole 7 will push the locking slider 810 to move, thereby causing the locking slider 810 to move in the direction away from the insertion hole 831, thereby causing the first return spring 811 to contract. When the locking slider 810 contacts one end of the locking pin 814 during the movement, the locking slider 810 guides the locking pin 814 through its inclined surface, so that the locking pin 814 moves toward the side connecting chamber 801, thereby causing the second return spring 816 to contract. At the same time, the movable plug rod 803 drives the pressure plate 806 to move in the direction away from the detector body 1. When the locking When the locking pin 814 is aligned with the locking hole 817 and the locking hole 7, the locking pin 814 will pass through the locking hole 817 and insert into the locking hole 7 under the action of the elastic restoring force of the second return spring 816, so that the locking pin 814 limits the test card 5. After the test card 5 is used, the pressure plate 806 is pushed toward the detector body 1. At this time, the movable plug rod 803 drives the locking pin 814 to move toward the side connecting bin 801 through the oblique connecting rotating plate 815, so that the locking pin 814 is separated from the locking hole 7 and the locking hole 817. At this time, the locking slider 810 will quickly recover under the action of the elastic restoring force of the first return spring 811, so that the locking slider 810 quickly pushes the test card 5, so that the test card 5 is separated from the connecting bin 4 under the action of inertia. In this way, the test card 5 can be separated from the connecting bin 4 without contacting the test card 5, which is simple and hygienic to operate.

[0038] In this embodiment, by providing this structure, when the movable insertion rod 803 moves toward the side connecting bin 801 , the oblique connecting rotating plate 815 drives the locking pin 814 to move in a direction away from the connecting bin 4 .

[0039] Please refer to Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 The touch detection member includes a touch bin 802 installed on the detector body 1 and located outside the movable plug rod 803, a second static contact piece 824 is installed on the inner wall of the touch bin 802, and a second movable contact piece 823 located inside the touch bin 802 is provided on the movable plug rod 803. A guide sleeve 818 is installed on the inner wall of the filling hole 808, and a first static contact piece 819 is installed on the top of the inner wall of the guide sleeve 818.

[0040] In the present embodiment, when the test card 5 is not inserted into the connection compartment 4, the second return spring 816 is in an uncompressed state. At this time, the second movable contact piece 823 and the second stationary contact piece 824 are in a misaligned state. When the locking pin 814 is inserted into the locking hole 7, the second return spring 816 cannot be completely restored due to the obstruction of the blocking plate 813. At this time, the second movable contact piece 823 contacts the second stationary contact piece 824.
