[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1

[0028] Reference Figures 1-2 This is the first embodiment of the present invention, which provides a modular hazardous waste sampler. The modular hazardous waste sampler includes a main component 100, including a controller 101. A magnetic suction head 102 is fixed on the controller 101. A sampling head 103 is provided on one side of the magnetic suction head 102. A magnetic suction interface 107 that cooperates with the magnetic suction head 102 is fixed on the sampling head 103. Through the cooperation between the magnetic suction head 102 and the magnetic suction interface 107, the sampling head 103 can be quickly replaced, shortening the replacement time of the sampling head 103 and thus improving the sampling efficiency of hazardous waste.

[0029] The sampling heads 103 include suction type, spiral type, vacuum adsorption type and scraper type. The suction type is used for liquid sampling, the spiral type is used for hard waste sampling, the vacuum adsorption type is used for powder sampling, and the scraper type is used for viscous waste sampling. The controller 101 can be matched with each type of sampling head 103 to drive the sampling head 103 to complete the sampling work. This is the prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0030] A sealing assembly 200 is disposed on one side of the sampling head 103, including a sealing element 201. The sealing element 201 is used to seal the sampling port at the bottom of the sampling head 103 to prevent hazardous waste from leaking from the sampling port at the bottom of the sampling head 103 when the sampling head 103 is removed from the sampling container after sampling is completed, thus preventing pollution of the surrounding environment. A trigger element 202 is disposed on one side of the controller 101. The trigger element 202 cooperates with the sealing element 201 and is used to drive the sealing element 201 to complete the sealing work. Each sampling head 103 is provided with a sealing element 201.

[0031] The sealing element 201 includes a first fixing plate 2011 fixed to the sampling head 103. A rotating shaft 2012 is connected to the first fixing plate 2011 by a bearing. The first fixing plate 2011 provides stable support for the rotating shaft 2012. A second support plate 20114 is also connected to the rotating shaft 2012 by a bearing. The second support plate 20114 is fixed to the rotating shaft 2012 and provides auxiliary support for the rotating shaft 2012.

[0032] A movable block 2013 is sleeved on the rotating shaft 2012. A fixed shaft 2014 is fixed on the movable block 2013. A rotating plate 2015 is sleeved on the fixed shaft 2014. A baffle 2016 is fixed on one side of the rotating plate 2015. The baffle 2016 is used to seal and block the sampling port at the bottom of the sampling head 103 to prevent hazardous substances remaining in the sampling head 103 from leaking out. A force plate 2017 is fixed on the rotating plate 2015. A squeezing block 2018 is provided on one side of the sampling head 103. A second fixed plate 20115 is fixed at the bottom of the squeezing block 2018. The second fixed plate 20115 is fixed on the sampling head 103, and the squeezing block 2018 is fixed to one side of the sampling head 103 by the second fixed plate 20115.

[0033] The movable block 2013 is equipped with two sets of fixed shafts 2014, a rotating plate 2015 and a force plate 2017. The number of pressing blocks 2018 is the same as that of the force plate 2017 and they correspond one-to-one.

[0034] The rotation of the rotating shaft 2012 causes the moving block 2013 to move along the direction of the rotating shaft 2012 toward the first fixed plate 2011. During this process, the force plate 2017 will gradually approach the squeezing block 2018. When the two come into contact, the moving block 2013 continues to approach the first fixed plate 2011. The squeezing block 2018 applies a pushing force to the force plate 2017, causing the force plate 2017 to rotate, which in turn drives the rotating plate 2015 to rotate around the fixed shaft 2014, thereby causing the baffle 2016 to rotate as well, until the baffle 2016 contacts and squeezes the sampling port at the bottom of the sampling head 103, so that the baffle 2016 blocks the sampling port and prevents residual hazardous materials in the sampling head 103 from dripping from the sampling port.

[0035] Depending on the type of sampling head 103, the size of the baffle 2016 varies, and each baffle 2016 can block the sampling port at the bottom of the corresponding sampling head 103.

[0036] Example 2

[0037] Reference Figures 2-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, a spiral groove 2012-1 is provided on the rotating shaft 2012, and a slider 2019 is fixed on the moving block 2013. The slider 2019 slides in the spiral groove 2012-1. The spiral groove 2012-1 has a large pitch. A through groove 2013-1 corresponding to the rotating shaft 2012 is provided on the moving block 2013, and the slider 2019 is fixed to the inner wall of the through groove 2013-1.

[0039] When the rotating shaft 2012 rotates, the slider 2019 will slide in the spiral groove 2012-1. With the cooperation of the two, the moving block 2013 will slide along the rotating shaft 2012, thereby moving the moving block 2013 closer to the first fixed plate 2011.

[0040] Specifically, the trigger 202 includes a rotating shaft 2021 disposed on one side of the controller 101, a locking block 2022 fixed on the rotating shaft 2012, and a locking groove 2021-1 opened at the bottom of the rotating shaft 2021. The locking block 2022 can engage with the locking groove 2021-1. Through the cooperation of the two, when the rotating shaft 2021 is rotating, it can drive the rotating shaft 2012 to rotate synchronously.

[0041] When installing the sampling head 103, the angle needs to be adjusted to ensure that the card block 2022 can engage with the card slot 2021-1, so that the rotating shaft 2021 can drive the rotating shaft 2012 to rotate synchronously when it rotates.

[0042] Specifically, a first support block 2023 is provided on the outer sleeve of the rotating shaft 2021. The first support block 2023 is connected to the bearing of the rotating shaft 2021, so that the rotating shaft 2021 can rotate. The rotating shaft 2021 and the first support block 2023 always maintain a relative position. One end of the first support block 2023 is fixed on the controller 101 to provide stable support for the rotating shaft 2021.

[0043] Specifically, a knob 2024 is fixed on the rotating shaft 2021. Rotating the knob 2024 can drive the rotating shaft 2021 to rotate, which in turn drives the locking block 2022 to rotate, thereby rotating the rotating shaft 2012 and controlling the position of the moving block 2013.

[0044] Specifically, a torsion spring 20110 is sleeved on the fixed shaft 2014. The two ends of the torsion spring 20110 are fixed to the fixed shaft 2014 and the force plate 2017. The torsion spring 20110 is used to reset the force plate 2017 and the rotating plate 2015. In the initial state, when the moving block 2013 is in the highest position, the force plate 2017 will not contact the pressing block 2018. Under the action of the torsion spring 20110, the baffle 2016 will be located away from the sampling head 103, thereby avoiding interference with the normal sampling process of the sampling head 103.

[0045] After sampling is completed, the operator removes the sampling head 103 from the sample container and continuously rotates the knob 2024 to move the moving block 2013 downwards and cause the force plate 2017 and the rotating plate 2015 to rotate. When the moving block 2013 moves to the lowest position, the baffle 2016 fits against the sampling port at the bottom of the sampling head 103, thereby preventing hazardous materials from leaking from the sampling head 103. During the transfer of the sampling head 103, the operator needs to keep rotating the knob 2024 to ensure that the baffle 2016 fits tightly against the sampling port at the bottom of the sampling head 103.

[0046] Example 3

[0047] Reference Figures 1-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0048] Specifically, a rubber pad 20111 is fixed on the baffle 2016. The rubber pad 20111 enhances the sealing between the baffle 2016 and the bottom sampling port of the sampling head 103. The rubber pad 20111 is arc-shaped, and its shape corresponds to the bottom sampling port of the sampling head 103. Its size is slightly larger than the sampling port. By setting the arc, when the baffle 2016 and the bottom sampling port of the sampling head 103 are tightly fitted, the rubber pad 20111 is squeezed and a part of it can be located inside the sampling head 103, thereby improving the tightness.

[0049] Specifically, a spring 20112 is fixed to the bottom of the movable block 2013, and the other end of the spring 20112 is fixed to the first fixed plate 2011. The spring 20112 is used to apply a continuous pushing force to the movable block 2013 to ensure that the movable block 2013 will not move downward due to its own weight without other external forces, thereby driving the rotating shaft 2012 to rotate.

[0050] When the knob 2024 is rotated, the moving block 2013 moves downward, compressing the spring 20112. When the operator stops rotating the knob 2024, the spring 20112 will return to its original position, pushing the moving block 2013 upward to its initial position, while the rotating shaft 2012 will also rotate in the opposite direction, returning to its initial position.

[0051] Specifically, a protective cover 20113 is provided outside the spring 20112. The two ends of the protective cover 20113 are fixed to the moving block 2013 and the first fixed plate 2011. The protective cover 20113 has a foldable structure similar to a louver to prevent the spring 20112 and the spiral groove 2012-1 on the rotating shaft 2012 from directly contacting the outside. This is existing technology and will not be elaborated on in this solution. When the moving block 2013 is at the top, the protective cover 20113 is stretched, and when the moving block 2013 is at the bottom, the protective cover 20113 is compressed.

[0052] Specifically, a handle 104 is fixed on the controller 101, a control panel 105 is installed on the handle 104, and an alarm 106 is fixed on the controller 101. During sampling, the operator precisely controls the controller 101 through the control panel 105 and works with the sampling head 103 to complete the sampling work. The alarm 106 can sound an alarm after the normal sampling resistance is exceeded, thereby preventing damage to the entire device. This is existing technology, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0053] When using the sampling head 103, the angle needs to be adjusted to ensure that the card block 2022 can engage with the card slot 2021-1. Align the magnetic head 102 with the magnetic interface 107. Under the action of magnetic force, quickly connect the controller 101 and the sampling head 103. Then, place the sampling head 103 into the container to be sampled. The operator can precisely control the controller 101 through the control panel 105 and cooperate with the sampling head 103 to complete the sampling work.

[0054] After sampling is completed, the operator removes the sampling head 103 from the sampling container and continuously rotates the knob 2024, causing the rotating shaft 2021 to rotate, which in turn causes the locking block 2022 to rotate, thereby rotating the rotating shaft 2012. The rotation of the rotating shaft 2012 causes the moving block 2013 to move along the rotating shaft 2012 towards the first fixed plate 2011. During this process, the force plate 2017 will gradually approach the pressing block 2018. When the two make contact, the moving block 2013 continues to approach the first fixed plate 2011. The extrusion block 2018 applies a pushing force to the force plate 2017, causing the force plate 2017 to rotate, which in turn drives the rotating plate 2015 to rotate around the fixed shaft 2014, thereby causing the baffle 2016 to rotate as well, until the baffle 2016 contacts and squeezes the sampling port at the bottom of the sampling head 103. This causes the baffle 2016 to block the sampling port, and the rubber pad 20111 is squeezed, with a portion of it able to be located inside the sampling head 103, thereby improving the tightness and preventing residual hazardous materials inside the sampling head 103 from leaking from the sampling port and polluting the surrounding environment.

[0055] During the transfer of the sampling head 103, the operator needs to keep rotating the knob 2024 to ensure that the baffle 2016 is in close contact with the sampling port at the bottom of the sampling head 103.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
