Detailed implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides a Figures 1 - 3 total organic carbon analyzer combustion tube cleaning tool as shown.

[0025] Embodiment 1. The cleaning tool includes: a central rod 100, a compression umbrella-shaped brush head 101 and a holding handle 102. The central rod 100 is a hollow tube structure with both ends communicating. The compression umbrella-shaped brush head 101 is fixedly arranged at one end of the central rod 100. The outer side of the compression umbrella-shaped brush head 101 is a brush surface. The holding handle 102 is fixedly connected to the end of the central rod 100 away from the compression umbrella-shaped brush head 101. The holding handle 102 is made of an insulating and anti-slip material. Since the compression umbrella-shaped brush head 101 is in an umbrella shape and can be elastically expanded or contracted, after the compression umbrella-shaped brush head 101 extends into the inner wall of the combustion tube, it can adaptively adjust its own expansion degree according to the diameter change of the inner wall of the combustion tube to ensure the fitting state with the combustion tube. In this way, the user can drive the axial movement of the compression umbrella-shaped brush head 101 in the combustion tube by holding the holding handle 102 and cooperating with the central rod 100, so as to make the brushing operation on the inner wall of the combustion tube more convenient and labor-saving, and at the same time improve the work efficiency on the premise of ensuring the cleaning quality. In addition, the holding handle 102 can be made of an insulating and anti-slip material such as rubber or plastic, and its outer wall is designed with anti-slip, which can improve the comfort and stability of the user holding the holding handle 102, and also has an insulating protection effect, improving the safety of the user's manual holding and use.

[0026] Among them, the compression umbrella-shaped brush head 101 includes a T-shaped hinge head 103, a plurality of brush skeletons 104 and an elastic compression spring 110. A plurality of hinge blocks 106 are rotatably connected to the outer peripheral wall of the T-shaped hinge head 103 at intervals in an annular array. The end parts of the plurality of brush skeletons 104 are fixedly connected to the hinge blocks 106 at corresponding positions. A brush hair 105 is fixedly connected to the side of the brush skeleton 104 away from the T-shaped hinge head 103. The elastic compression spring 110 is used to drive the brush skeleton 104 to automatically rotate and expand outward on the T-shaped hinge head 103. The brush hair 105 is any one of special alloy materials or polymer materials. The end faces of the brush skeleton 104 and the brush hair 105 are preferably fan-shaped, so that the contact area of the brush skeleton 104 can be larger, increasing the scrubbing area. And by using a special alloy material of titanium alloy or a polymer material of polyurethane for the brush skeleton 104, the brush skeleton 104 has good wear resistance, corrosion resistance and high temperature resistance, so that the brush skeleton 104 is not easily damaged during the scrubbing process in the combustion tube, the scrubbing quality is higher, and the service life is longer. Then, by using the end of the brush skeleton 104, it can rotate at the position of the outer peripheral wall of the T-shaped hinge head 103 through the hinge block 106, so that the plurality of brush skeletons 104 can be expanded or retracted around the T-shaped hinge head 103. Among them, the elastic compression spring 110 can provide an elastic supporting force for the rotation and expansion of the brush skeleton 104, and by using the elastic deformation performance of the elastic compression spring 110, the plurality of brush skeletons 104 can be rotated and retracted to achieve the functions of compression and expansion, meeting the requirement that the brush hair 105 can adaptively fit according to the change of the inner diameter of the combustion tube wall.

[0027] Furthermore, the compression umbrella-shaped brush head 101 further includes a circular hinge seat 108. A plurality of expansion arms 109 are rotatably connected to the outer peripheral wall of the circular hinge seat 108 at intervals in an annular array. One end of each of the plurality of expansion arms 109 away from the circular hinge seat 108 is hinged to the side wall of the brush skeleton 104. In the middle of one side of the circular hinge seat 108 close to the T-shaped hinge head 103, a connecting shaft 107 is fixedly connected. One end of the connecting shaft 107 sequentially passes through the T-shaped hinge head 103 and the inner cavity of the central rod 100 and is fixedly connected to a handle head 111. An elastic compression spring 110 is sleeved at the position between the central rod 100 and the handle head 111 on the outer wall of the connecting shaft 107. Through the arrangement of the circular hinge seat 108 and the expansion arms 109, it can play a role in auxiliary support and control for the rotation of the brush skeleton 104, enabling the circular hinge seat 108 to drive the expansion arms 109 to move through axial movement, so that one end of the expansion arm 109 provides a pulling force or a pushing force on the brush skeleton 104, thereby realizing the rotational expansion or contraction action of the brush skeleton 104. The connecting shaft 107 extends to the other end of the central rod 100 and then the handle head 111 is installed for limiting, and the elastic compression spring 110 is installed at the position between the handle head 111 and the central rod 100. The elastic deformation of the elastic compression spring 110 can be used to provide an elastic force for the brush skeleton 104 to maintain the expanded state, and it is also convenient for the user to drive the connecting shaft 107 to move towards the compression umbrella-shaped brush head 101 by pressing the handle head 111, so that the connecting shaft 107 drives the circular hinge seat 108 to move away from the T-shaped hinge head 103, thereby achieving the control of the rotational folding of the brush skeleton 104 and making the operation of folding the brush skeleton 104 into the combustion tube more convenient.

[0028] Embodiment 2: On the basis of Embodiment 1, it is further illustrated that an adjustment screw hole 113 is provided at one end of the connecting shaft 107 close to the handle head 111. One end of the handle head 111 close to the connecting shaft 107 is fixedly connected with a pressure regulating screw rod 112. The outer wall of the pressure regulating screw rod 112 is threadedly connected with the inner wall of the adjustment screw hole 113. In this embodiment, by providing the adjustment screw hole 113 at the end face of the connecting shaft 107 and setting the pressure regulating screw rod 112 at the end face of the handle head 111 to form a threaded connection with the adjustment screw hole 113, the distance between the 11 and the end face of the central rod 100 can be adjusted by driving the pressure regulating screw rod 112 to rotate clockwise or counterclockwise through the handle head 111, so as to achieve the adjustment of the initial compression amount of the elastic compression spring 110; in addition, the threaded connection between the adjustment screw hole 113 and the pressure regulating screw rod 112 also facilitates the disassembly of the handle head 111 at one end of the connecting shaft 107, so that the handle head 111 and the elastic compression spring 110 can be disassembled for inspection or replacement, more meeting the use requirements.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
