[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0018] Example 1, Figure 1 and Figure 2This is a schematic diagram of a biomimetic robot tear secretion system, including: a liquid source 1, a power mechanism 2, a biomimetic tear outlet 3, and a fluid passage 4; the first end 401 of the fluid passage 4 is connected to the liquid source 1, and the second end 402 of the fluid passage 4 is connected to the biomimetic tear outlet 3; the power mechanism 2 is disposed on the fluid passage 4 and is used to pump the liquid in the liquid source 1 to the biomimetic tear outlet 3.

[0019] Liquid source 1 can be a biocompatible reservoir or a replaceable reservoir bladder, capable of holding saline or artificial tears. The reservoir has a pre-installed filling port for rapid tear addition and replacement, or the reservoir bladder can be directly replaced. In this embodiment, a 2ml replaceable transparent reservoir bladder made of medical-grade silicone is used. It should be noted that the tears mentioned in this embodiment refer to the liquid in liquid source 1, which can be either saline or artificial tears.

[0020] The bionic tear outlet 3 includes at least one liquid discharge hole, such as Figure 1 As shown, liquid drainage holes are located on the surface of the bionic robot's simulated eye skin. In actual production, two or more liquid drainage holes can be fabricated on the surface of the bionic skin at the lower edge of the eyelid using laser equipment. The arrangement and shape of the drainage holes are not limited. Tears can drain through these holes, achieving a realistic tearing effect.

[0021] The fluid passage 4 uses a pipe device capable of transporting liquid. In this embodiment, a medical-grade PVC pipe is used. The first end 401 of the fluid passage 4 is connected to the liquid source 1, and the second end 402 of the fluid passage 4 is connected to the bionic tear outlet 3. A power mechanism 2 is provided on the fluid passage 4.

[0022] In Embodiment 1, the power mechanism 2 is a power mechanism 2 having an input end 201 and an output end 202, such as... Figure 1 As shown, in order to adapt to the power mechanism 2 with an input end 201 and an output end 202 set on the fluid passage 4, the fluid passage 4 adopts an I-type pipe structure. The input end 201 of the power mechanism 2 is set on the side of the fluid passage 4 near the liquid source 1, and the output end 202 of the power mechanism 2 is set on the side of the fluid passage 4 near the bionic tear outlet 3.

[0023] In the second embodiment of this utility model, the power mechanism 2 is a power mechanism 2 with a single port 203. For example... Figure 3 As shown, to accommodate the power mechanism 2 with a single port 203 installed on the fluid passage 4, the fluid passage 4 adopts a Y-shaped pipe structure 403, that is, the fluid passage 4 is provided with a third end that can be connected to a pipe, and the single port 203 of the power mechanism 2 is installed on the fluid passage 4 through the third end of the fluid passage 4. For details, please refer to... Figure 3 , Figure 3 This is the left view of the structural schematic diagram in Embodiment 2, and... Figure 2 The main view shown corresponds to this.

[0024] In Example 2, the Y-shaped pipe structure of fluid passage 4 adopts a miniature tee, such as Figure 2 and Figure 3 As shown, the first end 401 of the miniature tee is connected to the liquid source 1, the second end 402 of the miniature tee is connected to the bionic tear outlet 3, and the third end of the miniature tee is connected to the single port 203 of the power mechanism 2.

[0025] In Embodiments 1 and 2, a backflow prevention mechanism 5 can be configured on the fluid passage 4 to prevent liquid backflow. The number and location of the backflow prevention mechanism 5 are not limited. At least one backflow prevention mechanism 5 can be provided on the fluid passage 4 between the power mechanism 2 and the bionic tear outlet 3, or at least one backflow prevention mechanism 5 can be provided on the fluid passage 4 between the power mechanism 2 and the liquid source 1 (e.g.,...). Figure 2 At least one check valve 5 can be provided in both the fluid passage 4 between the power mechanism 2 and the bionic tear outlet 3, and the fluid passage 4 between the power mechanism 2 and the liquid source 1, located near the first end 401. The check valve 5 includes a one-way check valve and a capillary check structure. The one-way check valve uses a spring-loaded steel ball to prevent tear backflow, and the capillary check structure utilizes liquid surface tension to prevent backflow. In this invention, the check valve 5 includes a spring-loaded steel ball one-way check valve with a pressure of 0.5 kPa, thereby preventing tear backflow.

[0026] In this invention, the power mechanism 2 includes a pumping device, which includes a micro-pump, specifically a micro-pressure pump. Regarding the power structure, the pumping device can be a conventionally understood water pump, specifically a micro-pump, which can be a micro-pressure pump or a micro-diaphragm pump. Besides micro-pumps, conventional large-volume pumps can also be used. It should be noted that there is no conflict between the type of power mechanism 2 and the number of ports in the aforementioned power structure. The appropriate fluid passage 4 is selected for the number of ports in the power mechanism 2, and pumping functionality can be achieved regardless of the type of power mechanism 2. The power mechanism 2 uses existing technology; this invention relies solely on the pumping capacity of the power mechanism 2 to drive the tear fluid, without modifying the principle of the power mechanism 2 or involving its control logic.

[0027] In addition to pumping devices, non-pump power can also be used to drive tear discharge. In this case, a shape memory alloy spring can be used to drive the piston to discharge the tears.

[0028] In another embodiment of the present invention, a bionic robot includes a bionic robot tear secretion system as described in any of the above embodiments.

[0029] The beneficial effects of the bionic robot tear secretion system and the bionic robot provided by this utility model are as follows: The liquid source stores physiological saline or artificial tears to simulate the effect of real tears. A fluid passage connects the liquid source to the bionic tear outlet. A power mechanism drives the simulated tear liquid from the power source through the fluid passage to the bionic tear outlet. An optional check valve mechanism on the fluid passage prevents tear backflow. This structure, through the connection between the liquid source, power mechanism, bionic tear outlet, and fluid passage, enables tear drainage, allowing the bionic robot to produce tears, improving the realism of the bionic robot, and preventing tear backflow from contaminating electronic components.
