[0002] An existing tissue holder includes a base and a spring-loaded inner core. A column assembly is mounted on the base. The spring-loaded inner core and the column assembly are detachably connected. A roll of tissue paper is placed on the base, wrapped around the column assembly. The spring-loaded inner core includes a stain-removing spray. By pressing down on the spring-loaded inner core to separate it from the base, the stain-removing spray is used to spray away dirt. Then, a portion of the tissue paper roll is torn off to wipe away the dirt. Finally, the spring-loaded inner core is placed back on the base and pressed down again to reconnect it. The existing spring-loaded inner core has a complex structure, many parts, and high cost. Furthermore, the upper part of the stain-removing spray is always exposed, making it prone to dust accumulation and unsightly. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model first provides a spring-loaded inner core for detachably connecting to the base of a tissue holder. The base has a column assembly. The spring-loaded inner core includes a pressing component and a first elastic element. The upper and lower ends of the first elastic element abut against the pressing component and the column assembly, respectively. The pressing component includes a button and a slider assembly. The button and the top of the column assembly are vertically movably connected. The button and the slider assembly are slidably connected, pushing the slider assembly to move radially. The column assembly includes an inner cylinder portion. The slider assembly abuts against and is limited by the bottom of the inner cylinder portion in the vertical direction. When the button is pressed, the slider assembly moves radially to release the limitation between it and the inner cylinder portion. When the button is released, the first elastic element causes the pressing component to move upward and pop out, at which point the pressing component can detach from the column assembly for use.

[0004] Optionally, the slider assembly includes a first slider, a second slider, and a second elastic member, with the two ends of the second elastic member abutting against the first slider and the second slider respectively. The button pushes the first slider and the second slider closer together radially, and the second elastic member pushes the first slider and the second slider further away radially.

[0005] Optionally, the bottom of the button is provided with a pushing part, and both the first slider and the second slider are provided with an inclined first guide part. The first guide part of the first slider and the first guide part of the second slider are inclined in opposite directions, and the pushing part and the first guide part are slidably connected. When the button is pressed, the pushing part pushes the first guide part, causing the first slider and the second slider to move radially away. When the button is released, the first guide part pushes the pushing part upward.

[0006] Optionally, both the first slider and the second slider are provided with a second guide portion at their ends. The upper end of the second guide portion abuts and limits the bottom of the inner cylinder portion, and the lower end of the second guide portion is inclined. When the pressing component is inserted back into the column assembly after use, the second guide portion and the inner wall of the inner cylinder portion are slidably connected. The first slider and the second slider are radially close through the second guide portion until the pressing component is installed in place.

[0007] Optionally, the pressing assembly further includes a connecting cylinder, which is sleeved inside the upper end of the column assembly. The button and the connecting cylinder are vertically connected. The connecting cylinder is provided with a first limiting part, and the side wall of the button is provided with a second limiting part.

[0023] 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.

[0024] This utility model embodiment provides a bouncing inner core, combined with Figures 1 to 6As shown, a base 6 for detachably connecting a tissue holder is provided on the base 6. A column assembly 1 is provided on the base 6. The spring-loaded inner core includes a pressing component and a first elastic element 5. The upper and lower ends of the first elastic element 5 respectively abut against the pressing component and the column assembly 1. The pressing component includes a button 2 and a slider assembly 3. The top of the button 2 and the column assembly 1 are vertically connected. The button 2 and the slider assembly 3 are slidably connected and push the slider assembly 3 to move radially. The column assembly 1 includes an inner cylinder 111. The slider assembly 3 abuts against and limits the bottom of the inner cylinder 111 in the vertical direction. When the button 2 is pressed, the slider assembly 3 moves radially to release the limitation between it and the inner cylinder 111. When the button 2 is released, the first elastic element 5 drives the pressing component to move upward and pop out. At this time, the pressing component can be detached from the column assembly 1 and taken out for use.

[0025] Compared to existing technologies, the spring-loaded inner core of this invention uses the up-and-down movement of button 2 to drive the radial movement of slider assembly 3, thereby locking or unlocking the connection between the pressing assembly and column assembly 1. The structure is simple and ingenious, low in cost, and reduces the space occupied in the vertical direction.

[0026] like Figure 2 As shown, optionally, the slider assembly 3 includes a first slider 31, a second slider 32, and a second elastic member 33. The two ends of the second elastic member 33 abut against the first slider 31 and the second slider 32 respectively. The button 2 pushes the first slider 31 and the second slider 32 to move radially closer, and the second elastic member 33 pushes the first slider 31 and the second slider 32 to move radially away.

[0027] like Figure 1 and 3 As shown, in this embodiment, when the pressing component is installed in the column assembly 1, the first elastic element 5 is always in a compressed state, but the slider assembly 3 and the inner cylinder 111 cooperate to restrict the upward movement of the pressing component; when the button 2 is pressed, causing the slider assembly 3 to move radially and release the restriction, the first elastic element 5 drives the pressing component to move upward and pop out. In this embodiment, both the first elastic element 5 and the second elastic element 33 are springs, and the elastic force of the first elastic element 5 is greater than the elastic force of the second elastic element 33.

[0028] Optionally, the bottom of the button 2 is provided with a pushing part 21, and the first slider 31 and the second slider 32 are each provided with an inclined first guide part 311. The first guide part 311 of the first slider 31 and the first guide part 311 of the second slider 32 are inclined in opposite directions, and the pushing part 21 and the first guide part 311 are slidably connected. When the button 2 is pressed, the pushing part 21 pushes the first guide part 311, causing the first slider 31 and the second slider 32 to move radially away. When the button 2 is released, the first guide part 311 pushes the pushing part 21 upward.

[0029] like Figure 4 Taking the direction shown as an example, in this embodiment, the first guide portion 311 of the first slider 31 tilts to the left from top to bottom, and the first guide portion 311 of the second slider 32 tilts to the right from top to bottom. Both the first slider 31 and the second slider 32 are provided with receiving cavities, and the two ends of the second elastic member 33 are respectively accommodated in the two receiving cavities and abut against the inner wall of the receiving cavity.

[0030] Optionally, both the first slider 31 and the second slider 32 are provided with a second guide portion 312 at their ends. The upper end of the second guide portion 312 abuts and limits the bottom of the inner cylinder portion 111, and the lower end of the second guide portion 312 is inclined. When the pressing assembly is inserted back into the column assembly 1 after use, the second guide portion 312 and the inner wall of the inner cylinder portion 111 are slidably connected. The first slider 31 and the second slider 32 are brought closer together radially through the second guide portion 312 until the pressing assembly is installed in place.

[0031] like Figure 4 Taking the direction shown as an example, in this embodiment, the second guide portion 312 is located at the end of the first slider 31 that is away from the second slider 32. The second guide portion 312 of the first slider 31 is inclined to the right from top to bottom, and the second guide portion 312 of the second slider 32 is inclined to the left from top to bottom.

[0032] Optionally, the pressing assembly further includes a connecting cylinder 4, which is sleeved inside the upper end of the column assembly 1. The button 2 and the connecting cylinder 4 are connected vertically. The connecting cylinder 4 is provided with a first limiting part 41, and the side wall of the button 2 is provided with a second limiting part 22. The lower end of the first limiting part 41 abuts against the upper end of the second limiting part 22 to limit the upward movement distance of the button 2.

[0033] like Figure 2 and 4As shown, in this embodiment, the inner wall of the inner cylinder 111 and the connecting cylinder 4 are fixedly connected or integrally formed. The second limiting part 22 is inclined inward from top to bottom. When assembling parts, when the button 2 is pressed down, the inclined surface of the second limiting part 22 and the inner wall of the inner cylinder 111 slide together and undergo a slight deformation, so that the button 2 moves down smoothly until the second limiting part 22 and the bottom of the inner cylinder 111 are in contact.

[0034] Optionally, the connecting cylinder 4 is provided with a mounting part 44, the slider assembly 3 is installed in the mounting part 44, and the bottom of the button 2 is inserted into the mounting part 44 and then slidably connected with the slider assembly 3.

[0035] like Figure 6 As shown, in this embodiment, the mounting part 44 is located above the waist-shaped opening 45. When the pressing component is installed in the column assembly 1, the waist-shaped opening 45 and the stain-removing sprayer 7 are completely contained in the column assembly 1 and are not exposed, which can effectively prevent dust from entering and is also more aesthetically pleasing.

[0036] The mounting part 44 is provided with a mounting cavity 441 suitable for mounting the first slider 31 and the second slider 32. The mounting part 44 is provided with a fixing groove 442. The pushing part 21 of the button 2 passes through the fixing groove 442 and moves up and down in the fixing groove 442. The fixing groove 442 is used to prevent the pushing part 21 from moving circumferentially, so as to make the up and down movement structure of the button 2 more stable.

[0037] Both the first slider 31 and the second slider 32 have protrusions 313 at their upper ends. The protrusions 313 are adapted to abut against the inner wall of the bottom of the inner cylinder 111 to limit the radial movement. The mounting part 44 has a clearance opening 443 to allow the radial movement of the protrusions 313. At the same time, the outer wall of the second guide part 312 abuts against the inner wall of the outer casing 11 to limit the radial movement. The double limiting structure not only shares the elastic impact force of the second elastic element 33, but also makes the radial movement structure of the slider assembly 3 more stable.

[0038] like Figure 2 As shown, optionally, the connecting cylinder 4 is provided with a flange 42, and the bottom of the flange 42 is provided with a limiting groove 43. The upper end of the column assembly 1 is limited in the limiting groove 43, and the flange 42 facilitates the lifting of the connecting cylinder 4. In this embodiment, the limiting groove 43 is used to limit the downward movement of the connecting cylinder 4 to remind that it is installed in place.

[0039] Optionally, the column assembly 1 includes a housing 11 and a fixing base 12. The housing 11 is fixedly sleeved on the fixing base 12. The fixing base 12 is provided with a connecting post 121. The first elastic member 5 is sleeved on the connecting post 121 and abuts against the inner bottom wall of the fixing base 12. The bottom of the fixing base 12 is provided with a threaded post 122. The base 6 is provided with a threaded groove 61. The threaded post 122 and the threaded groove 61 are threadedly connected.

[0040] like Figure 1 and 3 As shown, in this embodiment, the column assembly 1 and the base 6 are detachably connected, which effectively saves space and facilitates storage, transportation, and packaging. The outer wall of the fixing seat 12 is provided with connecting textures to increase the friction between it and the outer shell 11, resulting in a better tight fit.

[0041] Since the cross-sections of the outer shell 11 and the inner cylinder 111 are both circular, and the slider assembly 3 and the inner cylinder 111 are upper and lower limiters, the pressing assembly does not need to be rotated to align the circumferential position during installation. It can be reconnected to the column assembly 1 simply by pressing down.

[0042] Optionally, it also includes a stain remover spray 7, which is housed in the housing 11 and is fixedly connected to the lower part of the pressing assembly. The upper end of the first elastic member 5 abuts against the bottom of the stain remover spray 7.

[0043] like Figure 1 and 5 As shown, in this embodiment, the bottom of the connecting cylinder 4 is fixedly connected to the stain remover sprayer 7. Specifically, the fixed connection can be a threaded connection or a tight fit connection with the bottle body of the stain remover sprayer 7. When the pressing component is pulled upwards, the stain remover sprayer 7 can be detached from the column assembly 1 for use.

[0044] The connecting cylinder 4 is provided with a waist-shaped opening 45, and the head of the stain remover sprayer 7 is located in the waist-shaped opening 45. The user can insert his / her finger into the waist-shaped opening 45 and press the head of the stain remover sprayer 7 to make the stain remover sprayer 7 spray out the spray.

[0045] Another embodiment of this utility model provides a tissue holder, including the spring-loaded inner core as described above.
