Abstract
Description
Technical Field
[0001] This utility model relates to the field of tissue holder technology, and more specifically, to a rotating and bouncing inner core and a tissue holder. Background Technology
[0002] An existing tissue holder includes a base and a spring-loaded inner core. The base has a column assembly, and the spring-loaded inner core and the column assembly are sleeved together. A tissue roll is sleeved over the column assembly and placed on the base. The spring-loaded inner core includes a stain-removing sprayer. By pressing the spring-loaded inner core downwards to separate it from the base, the stain-removing sprayer can be used to spray dirt. Then, a portion of the tissue roll is torn off to wipe away the dirt. Finally, the spring-loaded inner core is placed back on the base and pressed again to reconnect the spring-loaded inner core to the base.
[0003] The existing pop-up core has a noticeable jerking sensation during use. More importantly, when pressing down on the pop-up core, the stain-removing sprayer is prone to getting stuck and cannot be separated from the base, which seriously affects the user's experience with the tissue holder. Utility Model Content
[0004] To address at least one of the aforementioned problems, this utility model first provides a rotating spring-loaded inner core for detachably connecting to the base of a tissue holder. The base is provided with a column assembly. The spring-loaded inner core includes a pressing component and an elastic element. The upper and lower ends of the elastic element respectively abut against the pressing component and the column assembly. The column assembly includes a first toothed groove, a second toothed groove, a clearance cavity, and a rotating component. The height of the second toothed groove is greater than the height of the first toothed groove. The rotating component is vertically movable and connected to the first toothed groove, the second toothed groove, and the clearance cavity. The rotating component is rotatably sleeved on the pressing component. The rotating component is provided with a clamping part for clamping the pressing component.
[0005] When the pressing component is pressed, the pressing component causes the rotating component to move downward from the first tooth groove; when the pressing component is released, the elastic element causes the rotating component to move upward into the second tooth groove, and the clamping part moves upward into the relief cavity to relax the clamping effect on the pressing component, so that the pressing component can be pulled out for use.
[0006] Optionally, the column assembly includes a first sleeve and a second sleeve, the first sleeve is provided with an upper gear ring, the second sleeve is provided with a lower gear ring, the rotating component is provided with a mating block, the mating block rotates and moves up and down between the upper gear ring and the lower gear ring, and the first tooth groove and the second tooth groove are both provided on the upper gear ring.
[0007] Optionally, the upper gear ring has an inclined first sidewall and a vertical second sidewall on its protruding teeth, and the lower gear ring has an inclined third sidewall and a vertical fourth sidewall on its protruding teeth. The first sidewall and the third sidewall have the same inclination direction. The mating block has a first mating wall, a second mating wall, and a third mating wall. The first mating wall is slidably connected to the first sidewall, the second mating wall is slidably connected to the third sidewall, and the third mating wall is slidably connected to both the second and fourth sidewalls. The third sidewall is used to guide the mating block to rotate and move upward onto the first sidewall, and the first sidewall is used to guide the mating block to rotate into the first tooth groove or the second tooth groove.
[0008] Optionally, the second sidewall and the fourth sidewall are staggered in the vertical direction, the second sidewall is used to guide the mating block into the middle of the third sidewall, and the fourth sidewall is used to guide the mating block into the middle of the first sidewall.
[0009] Optionally, the side wall of the rotating component is recessed with a mounting groove, a mounting ring is installed in the mounting groove, and the mating block is disposed on the mounting ring.
[0010] Optionally, the rotating component has a mounting port on its side wall, and the clamping part is detachably installed in the mounting port. The clamping part is made of soft rubber.
[0011] Optionally, the first sleeve has a protruding limiting block on its side wall, and the second sleeve has a limiting opening at the upper end of its side wall. The limiting block is limited in the limiting opening. The column assembly includes a cover sleeve, the bottom of which abuts against the upper end of the limiting block. The second sleeve and the cover sleeve are simultaneously sleeved on the first sleeve. The clearance cavity is located between the upper end of the sleeve and the upper end of the first sleeve.
[0012] Optionally, the pressing assembly includes a limiting member, the side wall of which is provided with an elastic damping part, and the upper end of the cover cylinder is provided with an inward flange, the flange being used to limit the upward movement distance of the damping part.
[0013] Optionally, the bouncy inner core includes a stain-removing sprayer, which is fixedly connected to the lower part of the pressing assembly. The upper end of the elastic element abuts against the bottom of the stain-removing sprayer. A groove is provided circumferentially on the side wall of the stain-removing sprayer, and the clamping part abuts against the groove. The stain-removing sprayer and the clamping part are detachably connected.
[0014] Compared to existing technologies, the rotating bouncing inner core of this utility model uses an elastic element and a pressing component to move the rotating component from the first tooth groove to the second tooth groove, changing the height of the rotating component. This causes the clamping part to move upward and be located in the relief cavity, thereby relaxing the clamping effect on the pressing component. This allows the pressing component to be pulled out from the clamping part and used. The structure is stable and ingenious, reducing the feeling of jerking and making it less likely for the pressing component to get stuck.
[0015] In addition, this utility model provides a tissue holder, including the rotating and spring-loaded inner core as described above.
[0016] Compared to existing technologies, the tissue holder described in this utility model has the same advantages as the aforementioned rotating and bouncing inner core, which will not be repeated here. Attached Figure Description

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0028] This utility model embodiment provides a rotating bouncing inner core, combined with... Figures 1 to 8 As shown, a base 9 for detachably connecting a tissue holder is provided on the base 9. The base 9 is provided with a column assembly. The spring-loaded inner core includes a pressing assembly and an elastic element 7. The upper and lower ends of the elastic element 7 respectively abut against the pressing assembly and the column assembly. The column assembly includes a first tooth groove 111, a second tooth groove 112, a clearance cavity 4, and a rotating element 3. The height of the second tooth groove 112 is greater than the height of the first tooth groove 111. The rotating element 3 is vertically movable and connected to the first tooth groove 111, the second tooth groove 112, and the clearance cavity 4. The rotating element 3 is rotatably sleeved on the pressing assembly. The rotating element 3 is provided with a clamping part 34 for clamping the pressing assembly.
[0029] When the pressing component is pressed, the pressing component drives the rotating member 3 to move downward from the first tooth groove 111; when the pressing component is released, the elastic member 7 drives the rotating member 3 to move upward into the second tooth groove 112, and the clamping part 34 moves upward into the relief cavity 4 to relax the clamping effect on the pressing component, so that the pressing component can be pulled out for use.
[0030] like Figure 5 As shown, in this embodiment, the elastic element 7 is a spring. In the vertical direction, the apex of the second tooth groove 112 is higher than the apex of the first tooth groove 111. When the rotating element 3 is connected to the first tooth groove 111, the clamping part 34 is located at the lower end of the relief cavity 4, and the clamping part 34 cannot move radially to clamp the pressing component, at which time the pressing component cannot be pulled upward. When the rotating element 3 is connected to the second tooth groove 112, the clamping part 34 is located in the relief cavity 4 to relax the clamping effect on the pressing component. When an external force pulls the pressing component upward, the side wall of the pressing component pushes the clamping part 34 to move radially in the relief cavity 4 so that the pressing component can be pulled out smoothly.
[0031] Compared to existing technologies, the rotating bouncing inner core of this utility model, through the cooperation of the elastic element 7 and the pressing component, moves the rotating element 3 from the first tooth groove 111 to the second tooth groove 112, changing the height of the rotating element 3. This causes the clamping part 34 to move upward and be located in the relief cavity 4, thereby relaxing the clamping effect on the pressing component. This allows the pressing component to be pulled out from the clamping part 34 for use. The structure is stable and ingenious, reducing the feeling of jerking and making it less likely for the pressing component to get stuck.
[0032] Optionally, the column assembly includes a first sleeve 1 and a second sleeve 2. The first sleeve 1 is provided with an upper gear ring 11, and the second sleeve 2 is provided with a lower gear ring 21. The rotating component 3 is provided with a mating block 32. The mating block 32 rotates and moves up and down between the upper gear ring 11 and the lower gear ring 21. The first tooth groove 111 and the second tooth groove 112 are both provided on the upper gear ring 11.
[0033] like Figures 5 to 7 As shown, in this embodiment, the first sleeve 1, the second sleeve 2, and the rotating component 3 are all cylindrical. The first sleeve 1 is fitted onto the rotating component 3, and the second sleeve 2 is fitted onto the first sleeve 1. The first sleeve 1 and the second sleeve 2 are fixed together, that is, the upper gear ring 11 and the lower gear ring 21 do not rotate or move up and down.
[0034] Optionally, such as Figure 5 As shown, the upper gear ring 11 has an inclined first sidewall 113 and a vertically arranged second sidewall 114 on its convex teeth, as... Figure 6 As shown, the lower gear ring 21 has an inclined third sidewall 211 and a vertically arranged fourth sidewall 212 on its protruding teeth. The first sidewall 113 and the third sidewall 211 have the same inclination direction. Figure 7 As shown, the mating block 32 has a first mating wall 321, a second mating wall 322, and a third mating wall 323. The first mating wall 321 is slidably connected to the first side wall 113, the second mating wall 322 is slidably connected to the third side wall 211, and the third mating wall 323 is slidably connected to the second side wall 114 and the fourth side wall 212. The third side wall 211 is used to guide the mating block 32 to rotate and move upward onto the first side wall 113, and the first side wall 113 is used to guide the mating block 32 to rotate into the first tooth groove 111 or the second tooth groove 112.
[0035] Optionally, the second sidewall 114 and the fourth sidewall 212 are offset in the vertical direction. The second sidewall 114 is used to guide the mating block 32 into the middle of the third sidewall 211, and the fourth sidewall 212 is used to guide the mating block 32 into the middle of the first sidewall 113.
[0036] like Figures 5 to 7 As shown, in this embodiment, the mating block 32 is triangular, and the first sidewall 113 on the second tooth groove 112 is longer than the first sidewall 113 on the first tooth groove 111. When the mating block 32 moves down until the second mating wall 322 abuts against the third sidewall 211, because the lower tooth ring 21 is fixed, the mating block 32 rotates and moves down along the third sidewall 211 until it reaches the bottom of the third sidewall 211; when the elastic force of the elastic member 7 drives the mating block 32 to move up, the third mating wall 323 moves up along the fourth sidewall 212 until the first mating wall 321 abuts against the first sidewall 113. Because the upper tooth ring 11 is fixed, the mating block 32 rotates and moves up along the first sidewall 113 until it reaches the top of the first sidewall 113. At this time, the mating block 32 is confined in the first tooth groove 111 or the second tooth groove 112.
[0037] When the pressing component needs to be removed for use, the elastic element 7 is squeezed, and the mating block 32 bounces from the first tooth groove 111 to the second tooth groove 112; when the pressing component is used up and reinserted into the column assembly, the elastic element 7 is squeezed again, and the mating block 32 bounces from the second tooth groove 112 to the first tooth groove 111.
[0038] like Figure 7 As shown, optionally, the side wall of the rotating component 3 is recessed with a mounting groove, in which a mounting ring 31 is installed, and the mating block 32 is disposed on the mounting ring 31.
[0039] like Figure 7 As shown, optionally, the side wall of the rotating part 3 is provided with an installation port 33, and the clamping part 34 is detachably installed in the installation port 33. The clamping part 34 is made of soft rubber.
[0040] Optionally, the first sleeve 1 has a limiting block 12 protruding from its side wall, and the second sleeve 2 has a limiting opening 22 at its upper side wall. The limiting block 12 is limited in the limiting opening 22. The column assembly includes a cover sleeve 5, the bottom of which abuts against the upper end of the limiting block 12. The second sleeve 2 and the cover sleeve 5 are simultaneously sleeved on the first sleeve 1. The clearance cavity 4 is located between the upper end of the sleeve and the upper end of the first sleeve 1.
[0041] like Figure 5 and 6 As shown, in this embodiment, there are two limiting blocks 12, one semi-circular and the other triangular. The shape of the limiting opening 22 is adapted to the shape of the limiting block 12. The limiting block 12 is confined in the limiting opening 22, preventing the first sleeve 1 and the second sleeve 2 from rotating relative to each other or moving up and down, thereby fixing the positions of the upper gear ring 11 and the lower gear ring 21.
[0042] like Figure 2and 8 As shown, optionally, the pressing assembly includes a limiting member 6, on the side wall of which a flexible damping part 61 protrudes. The upper end of the cover cylinder 5 has an inwardly extending flange 51, which limits the upward movement distance of the damping part 61. In this embodiment, the damping part 61 is made of soft rubber.
[0043] Optionally, the bouncy inner core includes a stain-removing sprayer 8, which is fixedly connected to the lower part of the pressing assembly. The upper end of the elastic member 7 abuts against the bottom of the stain-removing sprayer 8. A groove 81 is provided circumferentially on the side wall of the stain-removing sprayer 8, and the clamping part 34 abuts against the groove 81. The stain-removing sprayer 8 and the clamping part 34 are detachably connected.
[0044] like Figure 1 and 8 As shown, in this embodiment, the column assembly includes a housing and a fixing base. The housing is fixedly sleeved on the fixing base, and the elastic element 7 is accommodated in the fixing base and abuts against the inner bottom wall of the fixing base. The second sleeve 2 is fixedly sleeved on the housing, and the stain-removing sprayer 8 is accommodated in the housing.
[0045] The bottom of the fixing base is provided with a threaded post, and the base 9 is provided with a threaded groove. The threaded post and the threaded groove are threadedly connected. The column assembly and the base 9 are detachably connected, which can effectively save space and facilitate storage, transportation and packaging. The outer wall of the fixing base is provided with connecting texture to increase the friction between it and the outer shell, so as to make the connection tighter.
[0046] Another embodiment of this utility model provides a tissue holder, including the rotating and bouncing inner core as described above.
