Description

Technical Field

[0001] The present application relates to the technical field of daily necessities, and in particular to an extraction device. Background Art

[0002] At present, extraction devices such as paper drawers have been widely used in people's lives. Paper drawers are used to hold multiple tissues, and users can extract tissues from the paper drawers when they need paper. In practice, paper drawers include hanging paper drawers and ordinary paper drawers. Hanging paper drawers are used in hospitals, public toilets and other environments, while ordinary paper drawers are used in users' homes.

[0003] However, in practice, regardless of whether the user's hands are wet or not, the user will encounter great resistance when extracting tissue from the tissue box, which can easily damage the tissue, and ultimately result in the user being unable to extract the tissue completely from the tissue box, resulting in a poor user experience. When a small amount of tissue is left in the tissue box, the tissue is not heavy enough and will not sink, resulting in a poor feel when extracting tissue, or even unusable tissue even when there is tissue in the tissue box.

[0007] The present application provides a paper towel pre-pressing device that changes the pressure point according to the thickness of the paper towel and generates differential pressure. When there are enough paper towels in the paper drawer, the distance between the top surface of the paper towel and the rotation axis of the self-gravity compression unit is small, and the pressing member is pressed on the edge area of ​​the paper towel surface. When the number of paper towels gradually decreases, the distance between the rotation axis of the self-gravity compression unit and the top surface of the paper towel increases, the swing arm angle increases, and the pressure point of the pressing member moves toward the center of the paper towel, that is, the paper towel extraction port 21 moves, ensuring that the paper towel is not affected by the number and maintaining the pre-pressure that satisfies the paper drawing action.

[0008] In one embodiment, the resistance reducing surface includes a first inclined surface; a portion of the surface of the first inclined surface contacts the extracted object in the accommodating space.

[0009] In one embodiment, the resistance reducing surface further includes a first arc surface connected to the first inclined surface.

[0010] In one embodiment, the resistance reducing element is further provided with a second resistance reducing surface inclined away from the center of the extraction port, and the second resistance reducing surface is connected to the first arc surface.

[0011] In one embodiment, the inclination angle of the first inclined surface is 4° to 10°.

[0012] In one embodiment, the resistance reducing element is a ring structure.

[0013] In one embodiment, the resistance reducing element is made of self-lubricating material.

[0017] The beneficial effects of this application compared with the prior art are:

[0018] The present application provides an extraction device, which includes a shell, a cover and a resistance reduction element; wherein the shell and the cover are detachably connected; when the shell is covered on the cover, a storage space for accommodating an object to be extracted is formed; an extraction port is provided on the shell; the resistance reduction element is connected to the shell and is located at the extraction port; a resistance reduction surface inclined toward the center of the extraction port is provided on the resistance reduction element, and part of the surface of the resistance reduction surface is in contact with the object to be extracted in the storage space.

[0019] From the above content, it can be seen that in the present application, a resistance reduction element is arranged at the extraction port of the extraction device, and a first resistance reduction surface inclined toward the center of the extraction port is arranged on the resistance reduction element, so that part of the surface of the first resistance reduction surface is in contact with the extraction object, thereby reducing the contact area between the extraction device and the extraction object, effectively reducing the resistance when the user extracts the extraction object from the extraction port, so that the extraction object can be extracted more smoothly and completely, avoiding damage to the extraction object, and improving the user's experience.

[0039] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings.

[0040] The present application provides an extraction device 1, which is used to accommodate an extractable object. When a user needs to use the extractable object, the extractable object can be extracted from the extraction device 1. Exemplarily, the above-mentioned extractable object can be a paper towel, and the extraction device 1 is a paper towel box at this time. However, in practice, regardless of whether the user's hands are wet, the user will encounter greater resistance when extracting paper towels from the extraction box, which can easily damage the paper towels, and ultimately result in the user being unable to completely extract the paper towels from the paper towel box, resulting in a poor user experience. Exemplarily, the above-mentioned resistance is friction. In order to solve the above-mentioned problem, the present application provides an extraction device 1, and the specific structure of the extraction device 1 provided by the present application is described below.

[0041] Please refer to Figure 1 , which is a schematic diagram of the structure of the extraction device 1 when the cover 10 is covered on the housing 20 according to an embodiment of the present application. Figure 2 , which is a cross-sectional schematic diagram of the extraction device 1 shown in the first embodiment of the present application. Figure 3 , which is a schematic diagram of the structure of the extraction device 1 when the cover 10 is not covered on the housing 20 as shown in the first embodiment of the present application. Figure 4 , which is a bottom view of the extraction device 1 shown in one embodiment of the present application.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, the extraction device 1 in the present application includes a detachably connected shell 20 and a cover 10. When the cover 10 is covered on the shell 20, a receiving space 100 for receiving an extractable object is formed. For example, the extractable object may be a tissue or the like. The shell 20 and the cover 10 may be connected by snap fastening, or the shell 20 and the cover 10 may be connected by riveting, or the shell 20 and the cover 10 may be connected by bolts. The extraction device 1 is provided with an extraction port 21. Specifically, the extraction port 21 may be provided on the shell 20, or the extraction port 21 may be provided on the cover 10. Exemplarily, when the extraction device 1 is a hanging paper box, the extraction port 21 can be provided on the housing 20; when the extraction device 1 is an ordinary paper box, the extraction port 21 can be provided on the cover 10; wherein, the ordinary paper box refers to a paper box placed on a table or other place at home; the hanging paper box refers to a paper box hung on a wall, a dining table or other place; the opening direction of the extraction port 21 of the ordinary paper box faces upward, and dust easily falls inside the paper box; the opening direction of the extraction port 21 of the hanging paper box faces downward, and dust does not easily fall inside the paper box. Preferably, the extraction device 1 in the present application is a hanging paper box.

[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the extraction device 1 in the present application also includes a resistance reduction element 30, which is arranged on the extraction device 1 and located around the extraction port 21; the resistance reduction element 30 is provided with a first resistance reduction surface 32 inclined toward the center of the extraction port 21, and a part of the surface of the first resistance reduction surface 32 is in contact with the extracted object in the accommodating space 100; the first resistance reduction surface 32 is located in the accommodating space 100.

[0044] In the prior art, the surface of the extraction port 21 in the extraction device 1 is in contact with the extracted object, and the contact area is large, so the user encounters a large resistance when extracting the extracted object; in the present application, a resistance reduction element 30 is provided on the surface of the extraction port 21, so that part of the surface of the first resistance reduction surface 32 on the resistance reduction element 30 is in contact with the extracted object, reducing the contact area between the extraction device 1 and the extracted object, effectively reducing the resistance when the user extracts the extracted object from the extraction port 21, so that the extracted object such as paper towels can be extracted more smoothly and completely, avoiding damage to the extracted object, and improving the user's experience. In addition, in the present application, the structure of the extraction device 1 is simple.

[0045] Please refer to Figure 5 , which is a schematic diagram of a resistance reduction element 30 according to an embodiment of the present application. Figure 6 , which is a cross-sectional schematic diagram of a resistance reduction element 30 according to an embodiment of the present application. Figure 7 , which is shown in an embodiment of the present application Figure 2 In one embodiment, as shown in FIG. Figure 5 As shown, the resistance reducing element 30 may be an annular structure, and the resistance reducing element 30 surrounds the extraction port 21. In another embodiment, a plurality of resistance reducing elements 30 may be provided, and the plurality of resistance reducing elements 30 are symmetrically arranged around the extraction port 21. The resistance reducing element 30 may be fixed to the extraction device 1 by fixing glue, screws, etc., or a slit is provided on the resistance reducing element 30, and the resistance reducing element 30 is clamped on the extraction device 1 through the slit.

[0046] like Figure 6 As shown, the first resistance reducing surface 32 on the resistance reducing element 30 includes a first inclined surface 321, and a portion of the surface of the first inclined surface 321 contacts the extract in the accommodating space 100. Of course, it can be understood that the inclination angle of the first inclined surface 321 can be 4° to 10°. Preferably, the inclination angle of the first inclined surface 321 is 5°.

[0047] In one embodiment, if Figure 6 As shown, the first resistance reducing surface 32 further includes a first arcuate surface 322 connected to the first inclined surface 321. The first arcuate surface 322 does not contact the extracted object in the accommodating space 100.

[0048] In one embodiment, if Figure 6 As shown, the resistance reducing element 30 is further provided with a second resistance reducing surface 33 inclined away from the center of the extraction port 21, and the second resistance reducing surface 33 is connected to the first arc surface 322. The second resistance reducing surface 33 does not contact the extracted object in the accommodating space 100. Figure 7As shown, in this embodiment, a first protrusion 31 is provided on the surface of the resistance reduction element 30 opposite to the first inclined surface 321, and the first protrusion 31 is located in the extraction port 21. On the resistance reduction element 30, other surfaces opposite to the first inclined surface 321 except the first protrusion 31 are fixed on the extraction device 1.

[0049] In the above embodiment, part of the surface of the first inclined surface 321 in the extraction device 1 contacts the object to be extracted, and the contact area between the extraction device 1 and the object is small, so the resistance when the user extracts the object is smaller. In addition, a first arc surface 322 is provided on the resistance reduction element 30 to assist the user when extracting an object such as a tissue; a second resistance reduction surface 33 is provided on the resistance reduction element 30 to avoid obstruction when the user extracts an object such as a tissue, so that the user can extract the object from the extraction device 1 more easily and smoothly.

[0050] In one embodiment, the resistance reducing element 30 is a self-lubricating material; the extraction device 1 is a corrosion-resistant material. That is, the resistance reducing element 30 is made of a material having both self-lubricating and corrosion-resistant functions, and the housing 20 and the cover 10 are made of a material having corrosion-resistant functions. Exemplarily, the resistance reducing element 30 can be made of materials such as POM, nylon, Teflon, and ABS; the housing 20 and the cover 10 can be made of ABS material.

[0051] By using self-lubricating material to make the resistance reduction element 30, it is ensured that the resistance reduction element 30 can have high self-lubricating properties, so that the user can extract the extract more easily. Using corrosion-resistant materials to make the extraction device 1 prevents the extraction device 1 from being corroded in environments such as hospitals, thereby improving the corrosion resistance of the extraction device 1. In addition, compared with metal materials, the extraction device 1 is made of plastic materials in the above embodiments of the present application, which simplifies the processing difficulty of the extraction device 1.

[0052] Please refer to Figure 8 , which is a schematic diagram of a hidden hanging opening 22 shown in an embodiment of the present application. Figure 8 As shown, the extraction device 1 is provided with a hidden hanging opening 22, and the extraction device 1 can be hung on the wall of a hospital or other places where the extraction device 1 is needed through the hidden hanging buckle.

[0053] Please refer to Fig. 9 , which is a schematic diagram of an observation window 23 shown in an embodiment of the present application. Fig.10 , which is a cross-sectional schematic diagram of the extraction device 1 shown in the second embodiment of the present application. Fig.11 , which is a three-dimensional schematic diagram of an extraction device 1 according to an embodiment of the present application. Fig.12 , which is a schematic diagram of the structure of the extraction device 1 when the cover 10 is not covered on the housing 20, as shown in the second embodiment of the present application. Figure 10-12As shown, the extraction device 1 also includes a self-gravity compression unit; wherein, the self-gravity compression unit is arranged in the accommodation space 100, and the self-gravity compression unit includes a rotating shaft 41, a swing arm 42 and a pressing member 43; one end of the swing arm 42 is rotatably connected to the extraction device 1 through the rotating shaft 41, and the pressing member 43 is connected to the other end of the swing arm 42, and the pressing member 43 is used to press the extracted object in the accommodation space 100. Specifically, for a hanging paper box, one end of the swing arm 42 can be rotatably connected to the cover body 10. When the extracted object is a paper towel, multiple paper towels are stacked together, the lowest paper towel contacts a part of the surface of the first inclined surface 321, and the pressing member 43 presses on the uppermost paper towel.

[0054] When there are a large number of paper towels in the accommodating space 100, the distance between the top paper towel and the rotating axis 41 of the self-gravity compression unit is small, and the pressing member 43 is pressed on the edge of the top paper towel surface; when the number of paper towels gradually decreases, the swing arm 42 gradually rotates around the rotating axis 41, and the distance between the rotating axis 41 of the self-gravity compression unit and the top paper towel gradually increases, the angle of the swing arm 42 gradually increases, and the point of force of the pressing member 43 gradually moves toward the center of the paper towel, that is, the center of the extraction port 21, and the pressing force of the pressing member 43 on the paper towel gradually increases, and the user can still smoothly extract the paper towel from the extraction device 1.

[0055] In the prior art, when there are a few tissues left in the extraction device 1, the tissues have insufficient gravity and will not sink automatically, resulting in a poor feel for the user to extract tissues, and even a situation where there is tissue in the tissue box but it cannot be used. In this embodiment, a self-gravity compression unit is provided in the extraction device 1, so that when there are a small number of tissues in the extraction device 1, the pressing force on the tissues is increased to maintain the pre-pressure required for the extraction action; so that the tissues can be extracted smoothly, avoiding the situation where there is tissue in the extraction device 1 but it cannot be extracted, and enabling the user to have a good experience of extracting tissues.

[0056] In one embodiment, the pressing member 43 may be a rolling body, or the outer surface of the pressing member may be a smooth structure. When the pressing member 43 is a rolling body, or the outer surface of the pressing member 43 is a smooth structure, during the movement of the point of force of the pressing member 43 toward the center of the extraction port 21, the resistance between the pressing member 43 and the surface of the paper towel is smaller, and the pressing member 43 can move more smoothly, effectively avoiding damage to the paper towel caused by the pressing member 43, and protecting the paper towel.

[0057] In one embodiment, if Fig. 9 and Fig.12As shown, the pressing member 43 is provided with a luminous label 431, and the extraction device 1 is provided with an observation window 23; illustratively, the observation window 23 can be provided on the housing 20. When the number of extracts in the accommodating space 100 decreases, the swing arm 42 will gradually rotate around the rotation axis 41, and the pressing member 43 will also gradually rotate under the drive of the swing arm 42; during the rotation process, the distance between the pressing member 43 and the rotation axis 41 changes, and the pressing member 43 is in different positions; when the number of extracts in the accommodating space 100 is small, the user can observe the luminous label 431 through the observation window 23; at this time, more extracts can be added to the housing 20.

[0058] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
