[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0032] The present invention will be further described below with reference to the embodiments.
[0033] Example:
[0034] This paper proposes an internal cleaning structure for a circular core, see attached document. Figures 1-5 This structure mainly includes a tube 1 for insertion into the core tube. The tube 1 is made of plastic and has a cavity inside. One end of the tube 1 is detachably connected to one end of the vacuum cleaner duct. Before use, one side of the tube 1 is connected and fixed to one end of the vacuum cleaner duct, and the other end of the tube 1 is inserted into the core tube to be cleaned. The vacuum cleaner is then turned on. In this embodiment, a vent 2 is provided on the outer wall of the tube 1, which communicates with the cavity inside the tube 1. At this time, the negative pressure provided by the vacuum cleaner is transmitted to the inner wall of the core tube through the tube 1, sucking away the impurities on the inner wall of the core tube.
[0035] In order to ensure the cleaning effect on the inner wall of the pipe, the pipe body 1 is usually closed at one end away from the dust collector air duct. In the embodiment, the pipe body 1 is detachably provided with a plug 3 at one end away from the dust collector air duct for the convenience of regular cleaning. When the dust collector is started, part of the adsorbed impurities will enter the dust collector through the dust collector air duct, and the other part of the impurities will be adsorbed in the pipe body 1. Therefore, after a period of use, the plug 3 can be removed from one end of the pipe body 1, and the impurities retained in the pipe body 1 can be poured out, thereby ensuring the smooth flow of the negative pressure air flow in the pipe body 1.
[0036] Optionally, the plug 3 in the embodiment can be made of rubber, and the overall diameter is slightly larger than the inner diameter of the pipe body 1, so that the plug 3 can be closely connected with the inside of the pipe body 1 when assembled.
[0037] In addition, in order to avoid the plug 3 being stuck in the pipe body 1 and being difficult to take out, a stop ring 10 is arranged in the pipe body 1. When the plug 3 is assembled, the plug 3 only needs to be inserted into the pipe body 1 and attached to the stop ring 10.
[0038] At the same time, the outer wall of the plug 3 is provided with an opening 31, so that the fingers can be inserted into and pulled out of the plug 3.
[0039] When the pipe body 1 is inserted into the inner wall of the pipe core, the distance between the pipe body 1 and the inner wall of the pipe core is at most 1 mm, and usually the distance between the pipe body 1 and the inner wall of the pipe core is between 0.5-1 mm.
[0040] It should be noted that the air hole 2 in the embodiment is not a point hole, but a long strip type long hole. The specific length is not limited too much. In the embodiment, the length of the air hole 2 is 5 cm.
[0041] In order to ensure that the negative pressure suction force can be adsorbed in multiple directions, the arrangement mode of the air hole 2 in the embodiment is one or more combinations of arrangement on the outer end surface of the pipe body 1 along the axis direction of the pipe body 1, arrangement along the circumferential direction of the pipe body 1 or inclined arrangement with the axis direction of the pipe body 1.
[0042] Specifically, when the air hole 2 is arranged on the outer end surface of the pipe body 1, there are three setting modes. One is that the air hole 2 is arranged along the axis direction of the pipe body 1 as shown in the accompanying Figure 2
[0043] The second is that the air hole 2 is arranged along the circumferential direction of the pipe body 1 as shown in the accompanying Figure 3
[0044] The third is that the air hole 2 is inclined and arranged at an angle with the axis of the pipe body 1 as shown in the accompanying Figure 4
[0045] The arrangement modes in the above can be combined for use, and will not be limited and described in detail here, and the drawings also do not show them.
[0046] Meanwhile, the air holes 2 are provided in plurality, the plurality of air holes 2 are circumferentially arranged on the outer circumferential surface of the pipe body 1, and the air holes 2 are at least divided into two columns along the axial direction of the pipe body 1, and each column of air holes 2 is circumferentially arranged on the outer circumferential surface of the pipe body 1.
[0047] When the air holes 2 are arranged on the outer end surface of the pipe body 1 along the circumferential direction of the pipe body 1, one of the air holes 2 in one column is located between the adjacent air holes 2 in the other column.
[0048] In addition, in order to increase the adsorption coverage area, the two adjacent air holes 2 along the axial direction of the pipe body 1 are staggered.
[0049] Meanwhile, due to the different lengths of the pipe cores, the length of the pipe body 1 can be adjusted to a certain extent, and the pipe body 1 can be provided in a multi-section telescopic structure, so that the telescopic length of the pipe body 1 can be adjusted according to the length of the pipe core.
[0050] In addition, a connecting pipe 11 can be threadedly connected to one end of the pipe body 1 close to the dust collector air pipe, and the depth of the threadedly connected connecting pipe 11 and the pipe body 1 can be adjusted according to actual needs, so as to achieve the purpose of adjusting the length of the pipe body 1.
[0051] One end of the connecting pipe 11 is detachably connected to the dust collector air pipe, and the detachable fixing mode is also not specifically limited, and in the embodiment, since most of the dust collector air pipes on the market are plastic flexible pipes, the cleaning structure in the embodiment is first inserted into one end of the connecting pipe 11 when assembled, and a screw hole is formed on the outer end surface of the connecting pipe 11, and a screw can be screwed into the screw hole to realize the fixation between the connecting pipe 11 and the dust collector air pipe.
[0052] The application further provides an application of the circular pipe core internal cleaning structure, that is, a circular pipe core cleaning device, which comprises the circular pipe core internal cleaning structure and a dust collector, and the circular pipe core internal cleaning structure is fixedly connected to the air pipe of the dust collector, and the pipe body 1 is inserted into the pipe core to be cleaned to clean the impurities attached to the inner wall of the pipe core.
[0053] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced equivalently; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present application.
