Description

Technical Field

[0001] This utility model relates to the field of hand drying device technology, and in particular to a fabric dispenser. Background Technology

[0002] Fabric dispensers are typically installed in restrooms to provide clean fabrics for users to dry their hands after washing. Traditional towel dispensers usually consist of a housing, one or more support shafts mounted within the housing, a drive roller, and multiple guide rods. When the drive roller is rotated, it pulls the towel strips to move and expose them at the dispensing opening in the housing, allowing the user to use the exposed towel strips to dry their hands. After the user has finished drying their hands, the corresponding support shaft rotates, retracting the used towel strips back into the housing.

[0003] In traditional fabric dispensers, because towel rolls are generally quite heavy, both ends of the support shaft are mounted on the internal structure of the housing to ensure the stability of the towel rolls within the housing. One end of the support shaft is connected to the housing, and a high-strength support structure is usually installed at the other end of the support shaft, away from the connection point with the housing, to ensure stable support for the fabric. The dispenser structure is relatively complex and not compact, requiring a large amount of space. Utility Model Content

[0004] This utility model provides a fabric distributor that ensures the stability and convenience of fabric roll installation while simplifying the equipment structure and improving its compactness.

[0005] A fabric dispenser, comprising:

[0006] A housing, comprising a cover, a back plate, and a middle plate, wherein the back plate and the middle plate are respectively fixed in position relative to the cover, and the middle plate and the cover enclose a cavity for receiving fabric; and

[0007] A support shaft passes through the middle plate and is connected at one end to the back plate, so as to support the support shaft together by the middle plate and the back plate, and at least part of the support shaft is suspended on the side of the middle plate opposite to the back plate to support the fabric.

[0008] In one embodiment, the support shaft includes a take-up shaft for securing used old fabric and being driven to rotate to wind the used old fabric around the take-up shaft.

[0009] In one embodiment, the support shaft includes a feed shaft that is parallel to and spaced apart from the take-up shaft, the feed shaft being used to thread the roll of fabric to be used.

[0010] In one embodiment, a fabric outlet for dispensing the fabric is provided below the cover.

[0011] In one embodiment, the fabric dispenser includes a first flexible partition disposed within the cavity, the first flexible partition being located between the feed shaft and the take-up shaft, and the first flexible partition being capable of changing its curvature according to changes in the radial dimension of the roll of fabric to be used or the roll of fabric already used.

[0012] In one embodiment, the fabric dispenser includes a panel connected to the housing, the panel being switched between an open state and a closed state relative to the housing; in the open state, the feed shaft and the take-up shaft are exposed; in the closed state, the panel covers the cavity; the panel includes a plate and a limiting member protruding from the inner side of the plate, the limiting member restricting the swing range of the free ends of the feed shaft and the take-up shaft in the closed state.

[0013] In one embodiment, the fabric dispenser includes a first roller disposed within the housing, and a feed drive roller and a take-up auxiliary roller disposed in parallel and at intervals. The feed drive roller is disposed corresponding to the first roller and is used to drive new fabric to be used to move out of the housing through the fabric outlet. The take-up auxiliary roller is used to guide the used old fabric to move towards the take-up shaft.

[0014] In one embodiment, the fabric dispenser includes a second roller that is parallel to and spaced apart from the first roller, the second roller being disposed corresponding to the take-up assist roller and used to squeeze the used old fabric between the take-up assist roller and the second roller.

[0015] In one embodiment, the fabric dispenser includes a connector to which the first roller and the second roller are respectively connected.

[0016] In one embodiment, the connector is detachably or movably disposed within the housing.

[0017] In one embodiment, the housing has a support groove for holding a roll of fabric to be used.

[0018] In one embodiment, the fabric dispenser includes any of the following:

[0019] The fabric dispenser includes an ultraviolet disinfection component disposed within the cavity;

[0020] The fabric dispenser includes an accelerated evaporation component disposed within the cavity, the accelerated evaporation component being configured for used old fabric, and the accelerated evaporation component including at least one of a blower and a heater.

[0021] The above-mentioned fabric dispenser includes a housing and a support shaft. The housing includes a cover, a back plate, and a middle plate. The back plate and the middle plate are fixed relative to the position of the cover, and the middle plate and the cover form a cavity for receiving fabric. The support shaft passes through the middle plate and is connected to the back plate at one end, so that the support shaft is supported by the middle plate and the back plate together, and at least part of the support shaft is suspended on the side of the middle plate away from the back plate to support the fabric. The support shaft is supported by the middle plate and the back plate. During the process of the support shaft supporting the fabric, the back plate and the middle plate can act as lever support. With a sufficiently rigid support shaft, the end of the support shaft away from the back plate does not need to be equipped with a high-strength support structure to ensure stable rigid support of the fabric by the support shaft. Therefore, while ensuring long-term stable operation, it simplifies the equipment structure, improves structural compactness, saves space, and allows users to more conveniently install or remove rolls of fabric to be used.

[0035] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0036] refer to Figure 1 and Figure 2 This application discloses a fabric dispenser 10, which can be installed in environments such as restrooms to provide users with hand towels. The fabric used in the fabric dispenser 10 is not limited to cloth towels, but can also be relatively thick or relatively absorbent paper towels or other materials.

[0037] Combination Figure 3 , Figure 4 and Figure 5The fabric dispenser 10 may include a housing 100 and a support shaft 200. The housing 100 includes a cover 110, a back plate 120, and a middle plate 130. The cover 110 may be a rounded rectangular frame, or a rectangular frame, an elliptical frame, or other shapes. The back plate 120 and the middle plate 130 are fixed relative to the position of the cover 110, and the middle plate 130 and the cover 110 enclose a cavity 100a for receiving the fabric 20. The back plate 120 and the cover 110 may be welded together, or they may be detachably connected using snap-fit ​​or threaded fasteners. The middle plate 130 and the cover 110 may be integrally formed, or they may be detachably connected using snap-fit ​​or threaded fasteners. For example, the middle plate 130 and the cover 110 are injection molded, and the back plate 120 is detachably connected to the middle plate 130 or the cover 110 by threaded fasteners, thereby achieving relative fixation of the positions of the back plate 120, the middle plate 130 and the cover 110, respectively. In some embodiments, the support shaft 200 is perpendicular to at least one of the back plate 120 and the middle plate 130 and perpendicular to the mounting wall, and one or more support shafts 200 can be provided, and can be further subdivided into feeding shafts 210 and receiving shafts 220 according to their functions, as detailed below.

[0038] In some embodiments, the depth of cavity 100a, i.e., the distance between the end of housing 110 away from back plate 120 and middle plate 130, is greater than the distance between middle plate 130 and back plate 120. In other words, the side of middle plate 130 away from back plate 120 has a relatively larger accommodating space. This larger accommodating space can be used to install unused fabric rolls 21 and to provide space for recycling used fabric rolls 23.

[0039] Continue to refer to Figure 5 The support shaft 200 passes through the middle plate 130 and is connected at one end to the back plate 120, so that the middle plate 130 and the back plate 120 jointly support the support shaft 200, and at least part of the support shaft 200 is suspended on the side of the middle plate 130 away from the back plate 120 to support the fabric 20.

[0040] In some embodiments, the side of the back plate 120 opposite to the middle plate 130 may have a recessed or protruding mounting structure for mounting the end of the support shaft 200. The support shaft 200 can be rotatably connected to the back plate 120, for example, through a rolling bearing or a sliding bearing, to reduce resistance during the movement of the fabric 20. Of course, this type of support shaft 200, which provides auxiliary support, can also be fixedly connected to the back plate 120 to simplify the connection structure.

[0041] refer to Figure 4The side of the middle plate 130 facing the back plate 120 can be equipped with a large number of reinforcing ribs and sleeves, which can improve the structural strength of the middle plate 130 while saving material costs, reducing weight, increasing internal space, and saving internal space. Meanwhile, large-size flange structures and a large number of screws are used at the connection points between the support shaft 200 and the middle plate 130 and back plate 120 to help distribute the torque borne by the middle plate 130 and back plate 120, ensuring that the support shaft 200 is firmly and stably fixed to the middle plate 130 and back plate 120. The space between the back plate 120 and the middle plate 130 can be used to configure a transmission structure such as a belt or chain, using a motor and transmission belt to drive one or more support shafts 200 to rotate, thereby moving new fabric 20 out of the housing 100 or retrieving used fabric 20 back into the housing 100. This arrangement allows for a relatively simple structure within the cavity 100a, providing convenience for users to replace the unused fabric roll 21 and retrieve the used fabric roll 23.

[0042] The middle plate 130 and the back plate 120 can act as lever supports for the support shaft 200. For the support shaft 200 that rotates relative to the back plate 120, rolling bearings or sliding bearings can be used to achieve the rotational connection between the support shaft 200 and the middle plate 130, ensuring smooth rotation of the support shaft 200. For those support shafts 200 that provide auxiliary support, when they are rotatably connected to the back plate 120, bearings can be used to achieve the rotational connection between the support shaft 200 and the back plate 120 and the middle plate 130. When they are fixedly connected to the back plate 120, they can be directly fixed through the back plate 120 and the middle plate 130, and the back plate 120 and the middle plate 130 can provide support.

[0043] Furthermore, in some embodiments, the structural strength of the back plate 120 can be greater than that of the middle plate 130. For example, the back plate 120 is made of stainless steel, while the middle plate 130 is made of plastic. The high-strength back plate 120 forms a stronger load-bearing support structure for the support shaft 200, while the relatively lower-strength middle plate 130 acts as an auxiliary fulcrum support. The two support the support shaft 200 together, which can ensure the stability of the support. At the same time, the support shaft 200 can be made of a large-diameter and high-strength metal material to provide sufficient rigidity and strength to prevent excessive deformation of the support shaft 200 during use, which could cause problems such as poor operation.

[0044] In some embodiments, the support shaft 200 includes a take-up shaft 220, which may include at least two opposing openable rods 221 and a take-up shaft sleeve 222 fitted at its free end. During the initial setting of the fabric roll 21's path, one end of the roll 21 to be used can be manually pulled, guiding it along the guide rods (first guide rod 230, second guide rod 240) and drive rollers within the fabric distributor 10. Figure 3The first roller (250) travels along the path set by the first roller and finally threads the initial section of fabric 20 between the rods 221, and then jogs the drive motor ( Figure 3 The take-up motor 510 drives the rod 221 to rotate, winding a portion of the fabric 20 onto the rod 221 to form a fabric roll. Then, during the equipment usage phase, as new fabric 20 is continuously distributed and used, the used fabric 20 is continuously collected and wound onto the take-up shaft 220, causing the diameter of the used fabric roll 23 to increase. Finally, when all the fabric 20 has been used and formed into used fabric rolls 23, the panel 140 of the fabric distributor 10 can be opened, the take-up shaft sleeve 222 removed, and the entire used fabric roll 23 pulled from the rod 221. The take-up shaft sleeve 222 is then reattached to the rod 221. The take-up shaft sleeve 222 helps to fix the position of the rod 221 and enhances the rigidity of the entire take-up shaft 220. It also serves to stop and limit the used fabric 20 and the used fabric roll 23. In other embodiments, the take-up shaft 220 may also adopt other structures for clamping the fabric 20, such as an openable clamp structure or a locking structure, which clamps the initial section of fabric 20 during the fabric feeding stage. When it is necessary to remove the old fabric roll 23, the locking device such as the locking buckle or elastic collar is opened to remove the entire old fabric roll 23.

[0045] Continue to refer to Figure 3 and combined Figure 5 In some embodiments, the support shaft 200 may include a feed shaft 210 parallel to and spaced apart from the take-up shaft 220. The fabric roll 21 to be used is sleeved on the feed shaft 210, so that the fabric roll 21 to be used can rotate more easily on the feed shaft 210, reducing the resistance to the movement of the new fabric 20 to be used and reducing the energy consumption of the feed motor 520. For example, the fabric roll 21 to be used includes a mandrel 21a and the new fabric 20 to be used wound around the mandrel 21a. The feed shaft 210 is used to pass through the mandrel 21a, and the mandrel 21a and the feed shaft 210 can be clearance-fitted.

[0046] Of course, the mandrel 21a of the fabric roll 21 to be used is not necessary. For example, the fabric roll 21 to be used can form a hollow cavity in its core area, and the hollow cavity can be directly sleeved onto the feed shaft 210 and clearance-fitted with the feed shaft 210. In some embodiments, the feed shaft 210 can be fixed to the middle plate 130 and the back plate 120, and the fabric roll 21 to be used can be driven to rotate by the feed motor 520; in some embodiments, the feed shaft 210 can be rotatably connected to the middle plate 130 and the back plate 120 through bearings, and the fabric roll 21 to be used and the feed shaft 210 can be driven to rotate together by the feed motor 520, reducing the resistance when the fabric roll 21 to release the fabric 20, thereby reducing the energy consumption of the fabric distributor 10.

[0047] It is understood that in some embodiments, the feeding shaft 210 may not be provided, and the roll of fabric 21 to be used may be placed directly in a support groove 100c, such as... Figure 6 As shown. At this time, the feeding motor 520 will pull the fabric 20 to distribute it, so that the fabric roll 21 to be used will rotate on its own in the support groove 100c. The support groove 100c can also separate the fabric roll 21 to be used from the fabric roll 23 that has been used. In this embodiment, the fabric distributor 10 does not need to be equipped with a feeding shaft 210, which simplifies the structure of the fabric distributor 10. However, the rotation of the fabric roll 21 to be used may be subject to a large frictional resistance from the support groove 100c, which may increase the energy consumption of the feeding motor 520 and put forward higher rigidity requirements on the corresponding support structure.

[0048] Combination Figure 3 , Figure 7 In some embodiments, the fabric dispenser 10 includes a panel 140 rotatably connected to a housing 110, the panel 140 being used to switch between an open and closed state relative to the housing 110; Reference Figure 3 When open, the feeding shaft 210 and the receiving shaft 220 are exposed; (Reference) Figure 1 In the closed state, panel 140 covers cavity 100a. Panel 140 may include plate 141 and limiting member 143 protruding from the inner side of plate 141, in combination with... Figure 5 When closed, the limiting member 143 can limit the swing range of the free end of the feeding shaft 210 and the free end of the receiving shaft 220.

[0049] Specifically, the plate 141 may be plate-shaped, and two spaced-apart limiting members 143 protruding from the plate 141 may be provided on its inner side. One limiting member 143 has a groove that matches the shape of the free end of the take-up shaft 220 and the size of the groove is slightly larger than the size of the take-up shaft sleeve 222. The other limiting member 143 has a groove that matches the shape of the free end of the discharge shaft 210 and the size of the groove is slightly larger than the size of the free end of the discharge shaft 210. After the panel 140 covers the cavity 100a, the two limiting members 143 respectively receive the free ends of the take-up shaft sleeve 222 and the discharge shaft 210, so that there is a gap between the take-up shaft sleeve 222 and the side wall of the groove, and there is a gap between the free end of the discharge shaft 210 and the side wall of the groove, so as to limit the swing range of the free ends of the discharge shaft 210 and the free ends of the take-up shaft 220.

[0050] The limiting member 143 restricts the swing range of the free end of the take-up shaft 220, preventing large-angle swings at the free end of the take-up shaft 220 from affecting the normal operation of the fabric distributor 10. Therefore, it ensures the long-term stable operation of the fabric distributor 10 and extends its service life. In an embodiment where the feed shaft 210 can rotate relative to the housing 100, this structure prevents interference or significant resistance to the rotation of the feed shaft 210. In an embodiment where the feed shaft 210 is fixed relative to the housing 100, this structure also limits the swing range of the feed shaft 210 driven by the new fabric 20 to be used, preventing large-angle swings at the free end of the feed shaft 210 from affecting the normal operation of the fabric distributor 10. Therefore, it ensures the long-term stable operation of the fabric distributor 10 and extends its service life.

[0051] Of course, it is understandable that the limiting member 143 of the panel 140 plays the role of limiting the swing range of the free end of the feeding shaft 210 and the free end of the receiving shaft 220. In the case of the default limiting member 143, the feeding shaft 210 and the receiving shaft 220 only need to meet the rigidity requirements, that is, the limiting member 143 of the panel 140 can be omitted.

[0052] Combination Figure 3 , Figure 5 In this embodiment, a fabric outlet 110a for dispensing fabric 20 is provided below the housing 110. After the fabric dispenser 10 is installed on a support such as a wall, the feed shaft 210, take-up shaft 220, and fabric outlet 110a are arranged approximately along the direction of gravity, with the take-up shaft 220 closer to the fabric outlet 110a than the feed shaft 210. This arrangement, compared to placing the feed shaft 210 closer to the fabric outlet 110a, prevents droplets from the used fabric roll 23 from dripping onto the unused fabric roll 21 under gravity and contaminating or wetting it, thus ensuring that the unused fabric roll 21 remains clean and hygienic. It is understood that in other embodiments, the feed shaft 210 or the unused fabric roll 21 may be positioned closer to the fabric outlet 110a.

[0053] Furthermore, the fabric dispenser 10 may include a first flexible partition 310 disposed within the cavity 100a. The fabric dispenser 10 includes two parallel and spaced-apart first guide rods 230. The two ends of the first flexible partition 310 are correspondingly sleeved or fixedly installed on the two first guide rods 230. The first flexible partition 310 is disposed between the feeding shaft 210 and the receiving shaft 220. The first flexible partition 310 may be made of materials such as plastic, rubber, silicone, or metal, and has a certain degree of flexibility or extensibility. It may be arc-shaped and protrude outward toward the fabric outlet 110a, thereby providing a space for the fabric roll 21 to be used. In addition, the structure of the first flexible partition 310 may also be configured so that the user can easily remove it from the cavity 100a to install the fabric roll 21 to be used or to recycle the used fabric roll 23, thereby improving the convenience of use. This will not be elaborated further here. The first flexible partition 310 can also prevent the used fabric roll 23 from contaminating the fabric roll 21 to be used. In other embodiments, the two ends of the first flexible partition 310 may also be fixed and assembled in other ways, such as being fixed to a separately provided rod or bracket.

[0054] Specifically, in some embodiments, the first flexible partition 310 has good elastic deformation or bending deformation properties, such as having a corrugated shape or other flexible and stretchable form, and the first flexible partition 310 can press against the fabric roll 21 to be used, and change the bending curvature with the change of the radial dimension of the fabric roll 21 to be used. For example, in its natural state, the arc length and bending degree of the first flexible partition 310 can be relatively small. When a new fabric roll 21 to be used is installed on the feeding shaft 210, the fabric roll 21 to be used can drive the first flexible partition 310 to produce relatively large or different bending deformations to press against the fabric roll 21 to be used; as the new fabric 20 to be used is gradually released, the radial dimension of the fabric roll 21 to be used decreases, and the deformation of the first flexible partition 310 also gradually recovers. On the one hand, the structure of the first flexible partition 310 can ensure the release stability of the new fabric 20 to be used, and prevent excessive fabric 20 from being pulled away from the fabric roll 21 to be used under inertia and accumulating in the cavity 100a, which would interfere with the movement of other moving parts. On the other hand, the structure of the first flexible partition 310 can adapt to the change of the radial dimension of the fabric roll 21 to be used, thereby reducing the distance between the feeding shaft 210 and the receiving shaft 220, making full use of the installation space in the cover 110, improving the structural compactness of the fabric distributor 10, and reducing the overall size of the fabric distributor 10.

[0055] Of course, the first flexible partition 310 can also be used to press against the used fabric roll 23 and change the curvature according to the change of the radial dimension of the used fabric roll 23, so as to ensure the winding stability of the used old fabric 20, reduce the distance between the feed shaft 210 and the take-up shaft 220, make full use of the installation space in the cover 110, improve the structural compactness of the fabric distributor 10, and reduce the overall size of the fabric distributor 10.

[0056] It is understood that in other embodiments, the first flexible partition 310 only has good bending deformation performance. The first flexible partition 310 may not be used to continuously press against the fabric roll 21 to be used. When it is pressed by the change in the radial dimension of the used fabric roll 23, it will change the bending direction and curvature accordingly.

[0057] It is understood that in other embodiments, the first flexible partition 310 may also be rigid or in other cover forms, serving only to separate the fabric roll 21 to be used from the fabric roll 23 already used.

[0058] The fabric dispenser 10 may further include a second flexible partition 320 disposed within the cavity 100a. Exemplarily, the fabric dispenser 10 includes two parallel and spaced-apart second guide rods 240, with the two ends of the second flexible partition 320 correspondingly fitted onto the two second guide rods 240. The second flexible partition 320 is disposed between the take-up shaft 220 and the fabric outlet 110a. The second flexible partition 320 may be made of materials such as plastic, rubber, silicone, or metal, possessing a certain degree of flexibility and extensibility. It may be arc-shaped and bulge outwards towards the fabric outlet 110a, thereby providing accommodating space for the used fabric roll 23. Bushing structures may be provided at both ends of the second flexible partition 320 to fit onto the second guide rods 240, thereby reliably positioning the second flexible partition 320 within the cavity 100a. When pulling out the fabric roll 21 for initial fabric feeding, the second flexible partition 320 can be manually lifted to provide a larger and more convenient feeding operation space.

[0059] In other embodiments, the second flexible partition 320 may also have good elastic deformation or bending deformation properties, such as having a corrugated shape or other flexible and stretchable shape, and the second flexible partition 320 may press against the fabric roll 21 to be used and change the bending curvature according to the radial dimension of the fabric roll 23 already used.

[0060] In some embodiments, the user can also remove the second flexible partition 320 from the cavity 100a to provide a larger and more convenient space for fabric movement. In other embodiments, the two ends of the second flexible partition 320 can also be fixed and assembled in other ways, such as being fixed to a separately provided rod or bracket.

[0061] It is understood that in other embodiments, the second flexible partition 320 may also be rigid or in other housing forms, serving only to separate the used fabric roll 23 from the lower components and structures of the fabric distributor 10.

[0062] refer to Figure 7 and Figure 8 The fabric dispenser 10 includes a pressure roller 400 disposed within a housing 110, and parallel and spaced-apart feeding drive rollers 250 and receiving auxiliary rollers 260. The pressure roller 400 includes a first roller 410, a second roller 420 parallel to and spaced-apart from the first roller 410, and a connector 430 connecting the first roller 410 and the second roller 420. Simultaneously combined with... Figure 3 The feeding drive roller 250 is correspondingly arranged with the first roller 410 and is used to drive the new fabric 20 to be used between the feeding drive roller 250 and the first roller 410 through the fabric outlet 110a to the outside of the housing 100 by the squeezing and traction action between the feeding drive roller 250 and the first roller 410. The receiving auxiliary roller 260 is correspondingly arranged with the second roller 420 and is used to squeeze the used old fabric 20 between the receiving auxiliary roller 260 and the second roller 420 so that the used old fabric 20 is more smoothly returned to the housing 100.

[0063] In some embodiments, the pressure roller 400 can be floatingly connected to the structural components within the middle plate 130 via elastic elements such as springs or sheet springs. This ensures that the first roller 410 exerts pressure on the new fabric 20 to be used, allowing the new fabric 20 to be used to be smoothly pulled to the fabric outlet 110a. At the same time, it provides a suitable floating space between the first roller 410 and the feeding drive roller 250, reducing the movement resistance of the new fabric 20 to be used. Furthermore, it ensures that the fabric 20 can be smoothly moved out of the fabric outlet 110a when changing to fabrics of different thicknesses, thus improving the versatility and adaptability of the fabric distributor 10.

[0064] The pressure roller 400 and the structural components inside the middle plate 130 can be floated, which also ensures the squeezing force of the second roller 420 on the used old fabric 20, so that the used old fabric 20 can be smoothly and evenly recycled into the housing 100. At the same time, it allows for a suitable floating space between the second roller 420 and the receiving auxiliary roller 260, reducing the movement resistance of the used old fabric 20. It also ensures that the fabric 20 can be smoothly and evenly recycled into the housing 100 when the thickness of the fabric 20 changes, thus improving the versatility and adaptability of the fabric distributor 10.

[0065] Continue to refer to Figure 7In some embodiments, the pressure roller 400 is detachably or movably disposed within the housing 100. For example, the connector 430 of the pressure roller 400 can be detachably connected to the baffle 150 by a snap-fit ​​connection. During the user's installation of the fabric roll 21 to be used, the pressure roller 400 can be removed from the baffle 150, and the pressure roller 400 can be moved out as a whole or swung up, providing the user with greater hand operation space while reducing the overall size of the fabric dispenser 10 and improving the compactness of the structure.

[0066] It is understood that in some embodiments, neither the second roller 420 nor the connector 430 is necessary, and either can be omitted or only one of them can be omitted. It is sufficient to use the take-up auxiliary roller 260 to guide the used old fabric 20 toward the take-up shaft 220. In addition, the first roller 410 and the second roller 420 can be set independently without being connected to each other, and both can be detachably or movably set in the housing 100.

[0067] Combination Figure 7 In this embodiment, the fabric dispenser 10 may include a take-up motor 510 and a feed-out motor 520. The housing 100 may also include a baffle 150, which is connected to the cover 110 and forms a mounting cavity 100b with the cover 110 (see reference). Figure 5 The take-up motor 510 and the feed motor 520 are both housed within the mounting cavity 100b. The mounting cavity 100b can be considered as a portion of the cavity 100a divided by the baffle 150. The output end of the take-up motor 510 passes through the middle plate 130 and extends between the middle plate 130 and the back plate 120, and is linked to the take-up shaft 220 via a belt drive structure; the output end of the feed motor 520 passes through the middle plate 130 and extends between the middle plate 130 and the back plate 120, and is linked to the feed drive roller 250 via another belt drive structure. During the operation of the fabric dispenser 10, the feeding motor 520 can first start for a first preset time, using the squeezing friction between the feeding drive roller 250 and the first roller 410 to pull a preset length of new fabric 20 to be used out of the fabric outlet 110a; after the user has finished wiping their hands with the fabric 20, the take-up motor 510 starts for a second preset time, using the take-up shaft 220 to pull the used old fabric 20 through the take-up auxiliary roller 260 and the second roller 420, using the squeezing force between the take-up auxiliary roller 260 and the second roller 420 to smoothly wind the preset length of used old fabric 20 onto the take-up shaft 220. The first preset time can be basically the same as the second preset time.

[0068] In some embodiments, the wheelbase between the feeding motor 520 and the feeding drive roller 250 is smaller than the wheelbase between the receiving motor 510 and the receiving shaft 220. With this arrangement, the belt drive distance of the feeding motor 520 is relatively short, which can reduce the transmission loss of the feeding motor 520 while improving the structural compactness, thereby saving energy.

[0069] Furthermore, the fabric dispenser 10 can be combined with an infrared sensor and a controller to achieve automated control. For example, the infrared sensor can detect the user's hand, and when the user's hand is placed in a certain area of ​​the fabric outlet 110a, the feeding motor 520 is started to distribute the new fabric 20 to be used outside the fabric outlet 110a; after the user's hand leaves, the take-up motor 510 is started, and the take-up shaft 220, combined with the squeezing action between the take-up auxiliary roller 260 and the second roller 420, smoothly winds the used fabric 20 onto the take-up shaft 220.

[0070] Understandably, as the fabric dispenser 10 continues to operate, the radial dimension of the used fabric roll 23 will increase. Each time a new piece of fabric 20 of the same length is removed from the fabric outlet 110a, the take-up time will decrease if the take-up motor 510 maintains a constant speed. Therefore, further automated control can be achieved by combining photoelectric sensors to keep the take-up time within a relatively constant range. For example, multiple photoelectric sensors can detect the radial dimension of the used fabric roll 23 wound on the take-up shaft 220. As the radial dimension of the used fabric roll 23 increases, the speed of the take-up motor 510 can be reduced in stages. For instance, three photoelectric sensors are arranged radially along the used fabric roll 23 in the housing 100, corresponding to the speed ranges of the three take-up motors 510. Whenever a photoelectric sensor is blocked, the controller reduces the speed of the take-up motor 510 by one level, thereby keeping the take-up time essentially constant.

[0071] In other embodiments, the fabric dispenser 10 may include an ultraviolet disinfection component (not shown) disposed in the cavity 100a. The ultraviolet disinfection component can be used to sterilize and disinfect the new fabric 20 to be used and the old fabric 20 that has been used, ensuring that the new fabric 20 to be used is clean and hygienic, and maintaining the hygiene of the old fabric 20 and the inside of the fabric dispenser 10.

[0072] The fabric dispenser 10 may also include an accelerated evaporation component (not shown) disposed within the cavity 100a. This accelerated evaporation component is configured to correspond to the used fabric 20 and includes at least one of a blower and a heater. When powered on, the accelerated evaporation component can blow air or heat the used fabric 20, increasing the evaporation rate of moisture in the used fabric 20, keeping the inside of the fabric dispenser 10 dry, and improving the user experience. Alternatively, a humidity sensor can be used to achieve automated drying. That is, the humidity sensor detects the humidity inside the fabric dispenser 10; when the humidity exceeds a threshold, the controller activates the accelerated evaporation component to reduce the humidity inside the fabric dispenser 10, ensuring the inside of the fabric dispenser 10 is dry and improving the user experience.

[0073] The fabric dispenser 10 includes a housing 100 and a support shaft 200. The housing 100 includes a cover 110, a back plate 120, and a middle plate 130. The back plate 120 and the middle plate 130 are fixedly connected to the cover 110. The middle plate 130 and the cover 110 enclose a cavity 100a for receiving fabric 20. The support shaft 200 passes through the middle plate 130 and is connected at one end to the back plate 120, so that the middle plate 130 and the back plate 120 jointly support the support shaft 200, and at least a portion of the support shaft 200 is suspended on the side of the middle plate 130 away from the back plate 120 to support the fabric 20. One end of the support shaft 200 is connected to the back plate 120, and the other end is suspended in the cavity 100a. It is supported by the middle plate 130 and the back plate 120. During the process of the support shaft 200 supporting the fabric 20, the back plate 120 and the middle plate 130 can act as lever support. With the support shaft 200 of appropriate rigidity, the end of the support shaft 200 away from the back plate 120 does not need to be equipped with a complex or high-strength support structure to ensure the rigid support of the support shaft 200 on the fabric 20. Therefore, while ensuring long-term stable operation, the equipment structure is simplified, the structural compactness is improved, and space is saved to ensure the volume of the cavity 100a. It also makes it easier for users to install the fabric roll 21 to be used or to take out the used fabric roll 23.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
