Description

Cleaning device

The present invention relates to a cleaning device, and more particularly to a cleaning device for manually cleaning dust, hair, cotton wool, etc. on a surface to be cleaned.

Referring to Figures 1 and 2, there is disclosed a conventional cleaning device 1 comprising a hand-held unit 11, two linkage units 12, and a cleaning unit 13 as disclosed in the Japanese Patent Publication No. CN 204033296 U. The hand-held unit 11 includes two hand-held bars 111 correspondingly coupled to each other, and two outer cover covers 112 respectively disposed on the upper and lower sides of the hand-held bars 111. The linkage units 12 are respectively rotatably disposed on the hand-held levers 111. Each of the linkage units 12 includes two upper and lower spaced rolling gears 121 and a follower gear interposed between the rolling gears 121. 122. The cleaning unit 13 includes two rollers 131 that are vertically parallel and removably sleeved between the rolling gears 121 of the linking units 12, a cleaning tape 132 that is wound around the periphery of the rollers 131, and a cleaning tape 132. A transition roller 133 that is parallel to the rollers 131 and that is coupled between the hand poles 111 is supported. In use, the user holds the hand-held bars 111 and rolls on a surface to be cleaned, and one of the rollers 131 releases the cleaning tape 132 via the linkage of the linking units 12, and the rollers 131 The other one will take up the cleaning tape 132 while adhering the cleaning tape 132 to the foreign matter on the surface to be cleaned.

However, since the cleaning tape 132 changes the thickness corresponding to the periphery of the rollers 131 as the rollers 131 roll, for example, when the first use is started, the cleaning tape 132 may be located around the periphery of the lower drum 131. The thickness may be greater than the winding thickness at the periphery of the upper roller 131, and after a period of use, the winding thickness of the cleaning tape 132 at the periphery of the lower roller 131 may be smaller than the winding thickness of the outer roller 131, but at the same When the diameters of the drums 131 are the same and the rotation speeds are the same, the cleaning tape 132 is released and the length of the cleaning tape 132 is not uniform, which may cause the cleaning tape 132 to loosen and slide, thereby affecting the smoothness of the operation. Although the cleaning device 1 causes the cleaning tape 132 to bypass between the rollers 131 and the transition roller 133, since the transition roller 133 is only pivoted at a fixed position, it cannot be used for moving and pushing. The cleaning tape 132 tightens the cleaning tape 132, so that the cleaning tape 132 is still loose, so the design of the cleaning device 1 still needs to be improved.

Accordingly, it is an object of the present invention to provide a cleaning apparatus that overcomes at least the disadvantages of the prior art.

Thus, the novel cleaning device comprises a hand-held unit, at least one linkage unit, a cleaning unit, and a tensioning unit. The at least one linkage unit is rotatably mounted to the hand-held unit and includes two rolling gears spaced apart and rotatable about its own axis, and a follower gear rotatably intervening between the rolling gears. And two rollers that are parallel and are respectively connected to the rolling gears. The cleaning unit includes a first roller and a second roller that are respectively detachably sleeved on the rollers, and a piece of cleaning tape that is wound and connected to the first roller and the second roller. When the interlocking unit is interlocked, one of the first roller and the second roller releases the cleaning tape, and the other of the first roller and the second roller winds up the cleaning tape. The tensioning unit includes a tension rod parallel to the first roller and the second roller and movably contacting a portion of the cleaning tape between the first roller and the second roller, and at least one connecting the tension bar and The hand-held unit and the constant drive cause the tension bar to stretch and tighten the elastic member of the cleaning tape.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to Figures 3 and 4, a first embodiment of the present cleaning apparatus includes a hand unit 2, a linkage unit 3, a cleaning unit 4, and a tension unit 5.

The hand-held unit 2 includes two left and right spaced side walls 21, a base wall 22 connecting one ends of the side walls 21, and a handle 23 connected to one side of the base wall 22 away from the side walls 21. Each of the side walls 21 is a plate that is bent at an angle, and has a forearm section 211 that is inclined downward toward the front, and a rear arm section 212 that is inclined rearwardly and downwardly from the rear end of the forearm section 211 to the rear arm section 212 that connects the base wall 22. Of course, the shape design of the side wall 21 is not limited to the first embodiment. The rear arm section 212 has a front and rear long extending guide groove 213 having a first groove end portion 214 on the front side and a second groove end portion 215 on the rear side. The guide groove 213 can be designed to penetrate both the inner and outer sides. Of course, in other variations, it may be recessed only to the inner side surface facing the other side wall 21 and not to the outer side surface. It should be noted that in other variations, the hand-held unit 2 may also have one of the side walls 21 in a detachable design or omit one of the side walls 21 from being disposed.

The linkage unit 3 is rotatably disposed on one of the side walls 21 and includes two rolling gears 31 which are spaced forward and backward and rotatably mounted about the front arm section 211 of the side wall 21, and a A follower gear 32 rotatably mounted to the forearm section 211 and interposed between the rolling gears 31, and two rollers 33 that are parallel to each other and connected to the rolling gears 31, respectively. In the first embodiment, each of the rollers 33 has a long and left extending rod body, and two lugs or screws respectively connected to the left and right ends of the shaft, and in other variations. Each of the rollers 33 may also be an integrally formed shaft, or may be composed of a shaft and a sleeve that is detachably and non-rotatably sleeved on the periphery of the shaft. The roller 33 may be constituted by two rotating blocks which are disposed at right and left and are concentrically arranged, and thus are not limited to the first embodiment.

The cleaning unit 4 is disposed between the side walls 21 and includes a first roller 41 and a second roller 42 which are respectively detachably and non-rotatably sleeved on the periphery of the rollers 33, and a piece of winding A cleaning tape 43 connected to the first roller 41 and the second roller 42. The cleaning tape 43 has a first winding section 431 which can be wound around the periphery of the first roller 41, a second winding section 432 which can be wound around the periphery of the second roller 42, and one of the first rollers A connecting portion 433 of the first winding section 431 and the second winding section 432 is connected to the same side of the second roller 42 and is connected in the same manner. The cleaning tape 43 has an inner side 434 facing the first roller 41 and the second roller 42, and an outer side 435 facing away from the first roller 41 and the second roller 42. It should be noted that the cleaning tape 43 is a roll of adhesive tape on one side, that is, the outer side surface 435 has adhesiveness, and the inner side surface 434 has anti-adhesive property, so it is easy to be layered after winding and laminating. Stripped.

The tensioning unit 5 includes a tension bar 51 parallel to the first roller 41 and the second roller 42 and movably contacting the inner side surface 434 of the cleaning tape 43, and two wires connected to the tension bar 51 An elastic member 52 between the end and the hand unit 2. The left and right ends of the tension bar 51 are embedded in the guide grooves 213 of the side walls 21, and can be driven relative to the hand unit 2 at a first position moved to the first groove end portions 214 (see Figure 4), and a second position (see Figure 5) moved to the second slot end 215. Each of the elastic members 52 is a tension spring, and the constant drive causes the tension rod 51 to stretch and tighten the cleaning tape 43. It is to be noted that the number of the elastic members 52 is not limited to two, and in other variations of the first embodiment, it may be one, three, or the like.

In the first embodiment, the first roller 41 wound with the unused cleaning tape 43 is sleeved on the front roller 33, and the second roller 42 is sleeved on the rear. a roller 33, and the end edge of the cleaning tape 43 is adhered to the second roller 42. At this time, the cleaning tape 43 wound around the first roller 41 exposes the handheld unit 2 to facilitate contact with a handle. Clean the surface, such as the table top, the floor or clothing...etc. Of course, the assembly is not limited thereto, and the first roller 41 and the second roller 42 may be reversely sleeved, so the assembly is not limited to the first embodiment.

In use, the user holds the handle 23 of the handheld unit 2, and causes the first winding section 431 wound around the periphery of the first roller 41 to roll back and forth on the surface to be cleaned, that is, through the cleaning. The tape 43 , the first roller 41 , the linking unit 3 and the second roller 42 are driven to each other such that the first roller 41 releases the unused or cleaned first winding segment 431 while allowing use or The dirty second winding section 432 is wound around the second roller 42, so that the cleaning tape 43 is wound around the periphery of the first roller 41 and the second roller 42 for adhesion. The foreign matter on the surface to be cleaned, such as dust, hair, cotton wool, and the like. Moreover, by the interlocking design of the linkage unit 3, the cleaning tape 43 can reciprocate in two directions, that is, the cleaning tape 43 can be moved not only from the first roller 41 to the periphery of the second roller 42 but also from the second The drum 42 is moved back to the outer periphery of the first roller 41, so that when the cleaning tape 43 is only stuck with a small amount or no sticky matter, it can be moved in two directions, until the glue is heavy or sticky, so that the cleaning is performed. The tape 43 continues to move for a length and is unwound for a new unused cleaning tape 43 so that the cleaning device can be sufficiently cleaned, is economical and resource efficient, and does not require manual peeling to remove the cleaning. The tape 43 is relatively convenient and easy.

It should be noted that during the rolling of the first roller 41 and the second roller 42, due to the winding thickness of the first winding segment 431 at the periphery of the first roller 41, and the periphery of the second roller 42 The winding thickness of the second winding section 432 is correspondingly changed according to the process of use, that is, the winding diameter of the first winding section 431 is different from the winding diameter of the second winding section 432, but When the diameters of the first roller 41 and the second roller 42 are the same, the length that the first winding segment 431 is released may be inconsistent with the length of the second winding segment 432 being retracted, and the connection is The segment 433 also changes the length, so the present invention utilizes the tension bar 51 to elastically stretch the connecting portion 433, so that the cleaning tape 43 can be wound tightly and not loosely in the first The drum 41 and the second drum 42 are placed on the drum 41.

The following further describes the use process as follows: as shown in FIG. 4, when not in use, the cleaning tape 43 is almost wound on the first roller 41, the length of the connecting section 433 is the shortest, and the tension bar 51 is located therein. First position. When the first winding section 431 has a winding thickness larger than the winding thickness of the second winding section 432, when the first roller 41 and the second roller 42 rotate one turn simultaneously, The length of the first winding section 431 to be released will be greater than the length of the second winding section 432 being retracted, so that the connecting section 433 will gradually become longer during the continued use, so The tension bar 51 is pulled by the elastic members 52 to gradually move from the first position to the second position until the winding thickness of the first winding segment 431 is equal to the second volume as shown in FIG. Between the winding thickness of the winding section 432, at this time, since the length of the first winding section 431 is released is equal to the length of the second winding section 432 being retracted, the length of the connecting section 433 is unchanged, and the tension rod is 51 is also pulled by the elastic members 52 to the second position. When the second winding section 431 is wound less than the winding thickness of the second winding section 432, the length of the first winding section 431 is released less than the second. The length of the winding section 432 is retracted, which will cause the connecting section 433 to be gradually shortened, and the tensioning rod 51 will gradually move from the second position to the first position until as shown in FIG. The tension bar 51 is moved to the first position, at which time the cleaning tape 43 is almost wound on the second roller 42, and the length of the connecting section 433 is the shortest.

It is worth mentioning that the elastic force of the elastic members 52 of the tensioning unit 5 is not greater than the meshing force of the linkage unit 3, and can be maintained in a force balance state, and can be used for the purpose of pulling and stopping, so that it is not used for cleaning. When the cleaning unit 4 is not driven to interlock the interlocking unit 3, the elastic force of the elastic members 52 cannot drive the tension rod 51 by the engagement of the rolling gear 31 and the follower gear 32 with each other. mobile.

Referring to Figure 7, a second embodiment of the present cleaning apparatus is substantially identical in construction to the first embodiment, except that the cleaning apparatus includes two left and right corresponding rotatably mounted to the side walls 21, respectively. The interlocking unit 3 can drive the cleaning unit 4 more stably, and has the functions of force average and smooth operation in use.

In summary, the cleaning device of the present invention elastically stretches the design of the cleaning tape 43 by the tensioning unit 5, so that the cleaning tape 43 can be wound tightly on the first roller 41 and the second roller. In the case of 42 , the cleaning device can have a smooth and smooth effect when it is actuated, so that the object of the present invention can be achieved.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
