[0022] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] like Figures 1-6 As shown, a handheld microfluidic chip water detector includes a handheld microfluidic chip water detector body 1. A holding mechanism 2 is provided on the right side of the handheld microfluidic chip water detector body 1. The handheld microfluidic chip water detector body 1 is used to detect water. The holding mechanism 2 is used to send the water to be tested into the handheld microfluidic chip water detector body 1 for testing, while avoiding the problem of water leakage during testing, which would lead to waste and test failure.

[0025] The holding mechanism 2 includes a receiving slot 203 inside the handheld microfluidic chip water detector body 1. A first mounting block 205 is inserted inside the receiving slot 203. An installation cavity 208 is opened inside the first mounting block 205. A second mounting block 206 is inserted inside the installation cavity 208. A holding cavity 212 is opened inside the second mounting block 206. A sealing plate 201 is fixedly installed on the right side of the first mounting block 205. The receiving slot 203 accommodates the first mounting block 205. The second mounting block 206 is installed through the first mounting block 205 and the installation cavity 208. The water to be tested is held through the holding cavity 212 inside the second mounting block 206, which facilitates subsequent component detection of the water by the handheld microfluidic chip water detector body 1.

[0026] A first pull ball 202 is fixedly installed on the right side of the sealing plate 201, and two second pull balls 207 are fixedly installed on the top of the second mounting block 206. The setting of the first pull ball 202 makes it easy to pull the sealing plate 201 together with the first mounting block 205 out of the inside of the storage groove 203, and to inject water into the inside of the holding cavity 212 for subsequent testing.

[0027] Limiting grooves 211 are provided inside the first mounting block 205 and on both sides of the mounting cavity 208. Limiting rods 213 are inserted inside the limiting grooves 211. One side of the limiting rods 213 is fixedly connected to the second mounting block 206. The second mounting block 206 is limited by the cooperation between the limiting grooves 211 and the limiting rods 213, thereby increasing the stability of the second mounting block 206.

[0028] The handheld microfluidic chip water detector body 1 has a sliding groove 204 at the bottom of the storage slot 203. A slider 210 is slidably connected inside the sliding groove 204. The top of the slider 210 is fixedly connected to the bottom of the first mounting block 205. The sliding groove 204 and the slider 210 increase the stability between the first mounting block 205 and the handheld microfluidic chip water detector body 1, thereby increasing the stability of the second mounting block 206 and facilitating subsequent water detection.

[0029] A spring 209 is fixedly installed on one side of the slider 210. One side of the spring 209 contacts the inner cavity of the slide groove 204. The spring 209 pushes the slider 210 to move the first mounting block 205 into the inside of the storage groove 203, thereby sending the second mounting block 206 into the inside of the storage groove 203, which facilitates subsequent water testing.

[0030] The handheld microfluidic chip water detector body 1 has an installation groove 3 on its right side. A rubber sealing gasket 4 is fixedly installed inside the installation groove 3. The right side of the rubber sealing gasket 4 contacts the left side of the sealing plate 201. The installation groove 3 and the rubber sealing gasket 4 increase the sealing between the right side of the handheld microfluidic chip water detector body 1 and the left side of the sealing plate 201.

[0031] A pin 214 is inserted into the right side of the top of the handheld microfluidic chip water detector body 1. The bottom of the pin 214 extends into the inside of the receiving groove 203. The pin 214 is used to block the first mounting block 205 when it is pulled out from the inside of the receiving groove 203, thereby facilitating the placement of the second mounting block 206 inside the mounting cavity 208 and facilitating subsequent water detection.

[0032] When water quality testing is required, the sealing plate 201, along with the first mounting block 205 and the second mounting block 206, is pulled out using the first pull ball 202. After the first mounting block 205 is pulled out, the pin 214 is inserted into the top of the handheld microfluidic chip water detector body 1 to block and limit the first mounting block 205. The second mounting block 206 is then removed, cleaned, and placed inside the mounting cavity 208, while the limiting rods 213 on both sides of the mounting cavity 208 penetrate into the limiting groove 211. After placement, the water droplet to be tested is placed inside. The water is poured into the holding cavity 212. After the water is poured in, the first pull ball 202 is held in hand while the pin 214 is removed. Under the compression of the spring 209, the slider 210 and the first mounting block 205 are pushed into the receiving groove 203. After the water is received, the water is tested by the handheld microfluidic chip water detector body 1 and the internal equipment. (The handheld microfluidic chip water detector body 1 integrates the detection equipment and microfluidic chip. The detection equipment and microfluidic chip are existing devices with mature technology, so they are not described in detail in this utility model.)

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
