[0025] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1:

[0027] This embodiment provides a test strip pushing device, such as Figures 1-6 As shown, it includes an outer shell 1, a transmission mechanism, a drive motor 2 and a rubber roller 3. The outer shell 1 provides support and connection for the transmission mechanism, the drive motor 2 and the rubber roller 3.

[0028] The outer shell 1 is provided with a conveying slot 13 for the test strip to pass through. The test strip is conveyed or retrieved in the conveying slot 13. The outer shell 1 is provided with an inner cavity 14. The drive motor 2 is connected to the outer shell 1, and its output end is connected to the rubber roller 3 through a transmission mechanism. The transmission mechanism is located in the inner cavity 14. The transmission mechanism operates in the inner cavity 14 without external interference, ensuring operational stability.

[0029] The rubber roller 3 is rotatably mounted at the bottom of the conveyor trough 13. The axis of the rubber roller 3 is perpendicular to the length of the conveyor trough 13. The surface of the rubber roller 3 provides sufficient friction to effectively propel the test strip. The drive motor 2 can drive the rubber roller 3 to rotate forward to convey the test strip out of the conveyor trough 13, or to rotate it backward to retract the test strip into the conveyor trough 13.

[0030] When the pushing device of the test paper of this embodiment is used, Figure 6 As shown, the test strip box 6 is installed on the upper side of the pushing device, and the lower side outlet of the test strip box 6 is aligned with the conveying groove 13 of the pushing device. The test strip 7 dropped from the test strip box 6 falls directly into the conveying groove 13, and the driving motor 2 drives the rubber roller 3 to rotate, thereby sending the test strip out of the conveying groove 13 or reversely rotating to retract the test strip into the conveying groove 13, thereby pushing the test strip so that the test strip can pass smoothly from the test strip box and be sent out of the system. The pushing device plays a role in receiving the test strip 7 dropped from the test strip box 6 and can push the test strip out when in use. When the pushing device is applied to the field of urine detection technology, the test strip is sent out of the equipment when in use, and the test strip is returned to the test strip box when not in use, preventing the test strip from being contaminated by the environment and improving the utilization rate of the test strip.

[0031] The test strip pushing device of this embodiment can prevent the test strip from being contaminated by the environment, improve the efficiency and accuracy of urine testing, and reduce the complexity of operation and potential contamination risks.

[0032] In a preferred embodiment, a position sensor 5 is installed at the outlet end of the conveyor trough 13. The position sensor 5 and the drive motor 2 are connected to the controller. A conveyor outlet 131 is provided at the outlet end of the conveyor trough 13. A mounting slot is provided above the conveyor outlet 131, and the position sensor 5 is installed in the mounting slot. The position sensor 5 is used to sense the presence of a test strip at the conveyor outlet 131.

[0033] When the test strip 7 is delivered to the outlet end of the delivery slot 13, the position sensor 5 detects the test strip 7 and transmits a signal to the controller, accurately detecting the arrival time of the test strip and recording the number of rotation steps.

[0034] As a preferred embodiment, Figure 2 and Figure 4 As shown, the transmission mechanism includes a first gear 41, a second gear 42, and a third gear 43. The first gear 41 is connected to the output shaft of the drive motor 2. The second gear 42 is disposed between the first gear 41 and the third gear 43 and meshes with the first gear 41 and the third gear 43, respectively. The third gear 43 is coaxially connected to the rubber roller 3 via a connecting shaft 44. The ends of the connecting shaft 44 are rotatably connected to the outer housing 1. The third gear 43 and the rubber roller 3 are fixedly connected to the connecting shaft 44.

[0035] The driving motor 2 drives the first gear 41 to rotate, and the first gear 41 drives the third gear 43 to rotate through the second gear 42, thereby driving the connecting shaft 44 and the rubber roller 3 to rotate. The transmission mechanism in this embodiment is driven by gears, which has good transmission stability, small space occupation, and compact connection.

[0036] As a preferred embodiment, Figure 4 As shown, the diameter of the second gear 42 is larger than that of the first gear 41, and the diameter of the second gear 42 is larger than that of the third gear 43. The second gear 42 is tightly connected to the first gear 41 and the third gear 43, and the transmission stability is good.

[0037] In addition, the diameter ratio among the first gear 41 , the second gear 42 and the third gear 43 can be adjusted as required.

[0038] In a preferred embodiment, the outer shell 1 includes a front shell 11 and a rear shell 12. The front shell 11 and the rear shell 12 are connected relative to each other, forming an inner cavity 14 therebetween, and a transfer groove 13 is formed on the top side of each. The transfer groove 13 extends in the left-right direction of the front shell 11 and the rear shell 12. The drive motor 2 is mounted on the front shell 11 or the rear shell 12.

[0039] The outer shell 1, formed by the combination of the front shell 11 and the rear shell 12, provides the necessary structural support and protection and secures the internal components. After the front shell 11 and the rear shell 12 are assembled, the gears are connected by transmission to form a closed transmission chain. Preferably, a pressure block is provided in the conveying groove 13 on the upper side of the rubber roller 3 near the outlet end, and the test strip is placed between the rubber roller 3 and the pressure block. When the drive motor 2 rotates, the rubber roller 3 is driven to rotate through the transmission mechanism, the test strip contacts the surface of the rubber roller, and the pressure block provides downward pressure. Under the action of friction, the test strip moves.

[0040] As a preferred embodiment, Figure 4 As shown, two second gears 42 and three third gears 43 are provided, with the two second gears 42 being located on the left and right sides of the first gear 41. Two rubber rollers 3 are provided, each connected to a connecting shaft 44. A single drive motor 2 simultaneously drives both rubber rollers to rotate, increasing the number of contact points with the test strip and thereby enhancing the pushing effect on the test strip.

[0041] As a preferred embodiment, both ends of the connecting shaft 44 are connected to the front housing 11 and the rear housing 12 respectively through bearings 45, thereby ensuring smooth rotation of the rubber roller and other rotating components, reducing friction loss, and improving system efficiency.

[0042] As a preferred embodiment, a receiving cavity 15 for accommodating a rubber roller is provided on both the front housing 11 and the rear housing 12, and the receiving cavity 15 on the front housing 11 and the receiving cavity 15 on the rear housing 12 are provided in a corresponding manner. The receiving cavity 15 is located below the conveying trough 13, and a through-port 16 communicating with the conveying trough 13 is provided on the upper side of the receiving cavity 15. When the rubber roller 3 rotates in the receiving cavity 15, the top side of the rubber roller 3 extends into the conveying trough 13 through the through-port 16, thereby allowing the rubber roller 3 to contact the test strip in the conveying trough 13, so that the rotation of the rubber roller 3 can drive the test strip to move.

[0043] When the test strip pushing device of this embodiment is in use, after receiving the working instruction from the controller, the drive motor 2 starts to work. The drive motor 2 drives the rubber roller 3 to rotate through the transmission mechanism. Under the action of the friction between the rubber roller 3 and the test strip 7, the test strip 7 is pushed toward the outlet end, and the pressure block applies appropriate pressure to ensure good contact between the test strip 7 and the rubber roller 3. The rubber roller 3 drives the test strip 7 to move forward and deliver a fixed length. The position sensor 5 at the outlet of the conveying trough detects the test strip 7 and begins to record the number of rotation steps. After the drive motor 2 receives the reversal instruction, the drive motor 2 rotates in the opposite direction and runs the recorded number of steps to return the test strip 7 to the test strip box 6 to avoid waste. Through the coordinated work of the drive motor 2 and the transmission mechanism, the accurate delivery and return of the test strip is achieved.

[0044] The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field can make several modifications and improvements without departing from the creative concept of the present invention, which should be included in the scope of protection of the present invention.
