Summary

The following is a summary of the subject matters described in detail in the present disclosure. This summary is not intended to limit the protection scope of the claims.
The embodiments of the present application provide a toilet paper holder, which can quickly perform replacement of a toilet paper and is easy to use.
A toilet paper holder includes a housing and a toilet paper bracket. A toilet paper accommodating cavity is provided in the housing, and has a toilet paper access opening and a first cavity wall disposed opposite to the toilet paper access opening. The toilet paper bracket is rotatably installed in the toilet paper accommodating cavity. The toilet paper bracket is configured to be capable of rotating towards the first cavity wall, so that the toilet paper bracket is in an access position in which the toilet paper bracket is configured to be capable of rotating into a hollow core of a toilet paper to install the toilet paper, or rotating out of the hollow core of the used toilet paper to remove the toilet paper. The toilet paper bracket is further configured to be capable of rotating toward the toilet paper access opening, so that the toilet paper bracket is in a support position in which the toilet paper bracket is configured to be located in the hollow core of the toilet paper to support the toilet paper.
In the toilet paper holder provided by the embodiments of the present application, a toilet paper accommodating cavity is provided in the housing and can be configured for accommodating the toilet paper. The toilet paper accommodating cavity has a toilet paper access opening, and the toilet paper can be installed into the toilet paper accommodating cavity from the toilet paper access opening and the toilet paper can be removed from the toilet paper access opening.
The toilet paper bracket is rotatably installed in the toilet paper accommodating cavity, so that the toilet paper bracket can be switched between an access position and a support position. The toilet paper bracket can rotate toward the first cavity wall opposite to the toilet paper access opening to the access position, and can rotate toward the toilet paper access opening to the support position.
During installation of the toilet paper, the toilet paper can enter the toilet paper accommodating cavity from the toilet paper access opening and move towards the first cavity wall, and the moving toilet paper can drive the toilet paper bracket to rotate to the access position. At this time, the toilet paper bracket can rotate into the hollow core of the toilet paper. Then, the toilet paper bracket rotates toward the toilet paper access opening to a support position, and the toilet paper falls back toward the toilet paper access opening and can be supported on the toilet paper bracket to complete the installation of the toilet paper.

Detailed Description

Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments can be arbitrarily combined with each other if there is no conflict.
As shown in FIGS. 1-4, an embodiment of the present application provides a toilet paper holder 100 including a housing 1 and a toilet paper bracket 2. A toilet paper accommodating cavity 13 is provided in the housing 1, and the toilet paper accommodating cavity 13 has a toilet paper access opening 14 and a first cavity wall 15 disposed opposite to the toilet paper access opening 14.
The toilet paper bracket 2 is rotatably installed in the toilet paper accommodating cavity 13. The toilet paper bracket 2 is configured to be capable of rotating toward the first cavity wall 15, so that the toilet paper bracket 2 is in an access position. In the access position (shown by dashed lines in FIG. 6 (b4)), the toilet paper bracket 2 is configured to be capable of rotating into a hollow core 42 of a toilet paper 4 (rotating from the state shown by dashed lines in FIG. 6 (b4) to the state shown by solid lines in FIG. 6 (b4)) to install the toilet paper 4 as shown in FIG. 6 (b5); or, the toilet paper bracket 2 is configured to be capable of rotating out of the hollow core 42 of used toilet paper 4 (rotating from the state shown by dashed lines in FIG. 7 (c3) to the state shown by solid lines in FIG. 7 (c3)) to remove the toilet paper 4 as shown in FIG. 7 (c4).
The toilet paper bracket 2 is further configured to be capable of rotating toward the toilet paper access opening 14, so that the toilet paper bracket 2 is in a support position shown in FIGS. 3, 4 and 6 (b5). As shown in FIG. 6 (b5), in the support position, the toilet paper bracket 2 is configured to be located inside the hollow core 42 of toilet paper 4 to support the toilet paper 4.
In the toilet paper holder 100 of an embodiment of the present application, a toilet paper accommodating cavity 13 is provided in the housing 1 and can be configured to accommodate the toilet paper 4. The toilet paper 4 includes a hollow core 42 located inside thereof and roll paper 41 wound on the hollow core 42. The toilet paper accommodating cavity 13 has a toilet paper access opening 14. The toilet paper 4 can be installed in the toilet paper accommodating cavity 13 from the toilet paper access opening 14 and removed from the toilet paper access opening 14.
The toilet paper bracket 2 is rotatably installed in the toilet paper accommodating cavity 13, so that the toilet paper bracket 2 can be switched between an access position and a support position. The toilet paper bracket 2 can rotate toward the first cavity wall 15 disposed opposite to the toilet paper access opening 14 to the access position, and can rotate from the access position toward the toilet paper access opening 14 to the support position.
As shown in FIG. 5 and FIG. 6, during installation of the toilet paper 4, the toilet paper 4 can enter the toilet paper accommodating cavity 13 from the toilet paper access opening 14 and move towards the first cavity wall 15, and the moving toilet paper 4 can drive the toilet paper bracket 2 to rotate to the access position. At this time, the toilet paper bracket 2 can rotate into the hollow core 42 of toilet paper 4. Then, the toilet paper bracket 2 rotates toward the toilet paper access opening 14 to the support position, and the toilet paper 4 falls back toward the toilet paper access opening 14 and can be supported on the toilet paper bracket 2 to complete the installation of the toilet paper 4.
As shown in FIG. 7, during removal of the used toilet paper 4 (such as exhausted toilet paper 4), the toilet paper 4 moves towards the first cavity wall 15 and drives the toilet paper bracket 2 to rotate to the access position. At this time, since the diameter of the used toilet paper 4 is reduced, the toilet paper 4 can be closer to the first cavity wall 15, so that the toilet paper bracket 2 can rotate out of the hollow core 42 of the toilet paper 4. Then, the toilet paper 4 can be removed from the toilet paper access opening 14. During the removal of the unused new toilet paper 4, the toilet paper 4 moves towards the first cavity wall 15 and drives the toilet paper bracket 2 to rotate to the access position. Since the unused new toilet paper 4 has a larger diameter, the toilet paper 4 is far from the first cavity wall 15, and the toilet paper bracket 2 cannot rotate out of the hollow core 42 of the toilet paper 4 under the barrier of the hollow core 42 of the toilet paper 4. Therefore, the unused new toilet paper 4 cannot be removed from the toilet paper holder 100, thus realizing the anti-theft of the toilet paper 4.
The toilet paper holder 100 of the embodiments of the present application can achieve the quick installation and removal operations of the toilet paper 4, so that the toilet paper 4 can be conveniently replaced, and the toilet paper can be prevented from being stolen, and is safe to use.
It should be understood that the toilet paper bracket 2 can rotate under the driving of the toilet paper 4, and there is no need to provide a driving mechanism for the toilet paper bracket 2. Alternatively, a driving mechanism may be provided to drive the toilet paper bracket 2 to rotate.
In some exemplary embodiments, as shown in FIGS. 2-4, the toilet paper bracket 2 includes a rotary connection part 22 rotatably connected with the toilet paper accommodating cavity 13 and a toilet paper support part 21 for supporting the toilet paper 4. As shown in FIG. 6 and FIG. 7, in the access position, the distance between the end of the toilet paper support part 21 away from the rotary connection part 22 and the first cavity wall 15 is L, the maximum thickness of the roll paper 41 of the toilet paper 4 is T, the outer diameter of the hollow core 42 of the toilet paper 4 is D, and the thickness of the hollow core 42 of the toilet paper 4 is t, where L≥T+t, L≥D, and L≤D+2^∗K^∗T, 0≤K < 1.
The toilet paper bracket 2 is rotatably connected with the toilet paper accommodating cavity 13 through the rotary connection part 22, and the toilet paper support part 21 can extend into the hollow core 42 of toilet paper 4 to support the toilet paper 4. In the access position, the distance between the end of the toilet paper support part 21 away from the rotary connection part 22 and the first cavity wall 15 is L. The maximum thickness of the roll paper 41 of the toilet paper 4 (i.e., the thickness of the toilet paper 4 when it is new and not used yet) is T, the outer diameter of the hollow core 42 of the toilet paper 4 is D, and the thickness of the hollow core 42 of the toilet paper 4 is t. As shown in FIG. 6, L≥T+t ensures that during installation of a new toilet paper 4, the roll paper 41 of the toilet paper 4 can completely enter between the toilet paper support part 21 in the access position and the first cavity wall 15, so that the end of the toilet paper support part 21 away from the rotary connection part 22 can face the cavity in the hollow core 42 of the toilet paper 4 so as to rotate the toilet paper support part 21 into the hollow core 42 of the toilet paper 4, achieving the installation of toilet paper 4.
As shown in FIG. 7, L≥D ensures that the hollow core 42 of the toilet paper 4 can completely enter between the toilet paper support part 21 in the access position and the first cavity wall 15 during removal of the exhausted toilet paper 4 (that is, when the roll paper 41 of the toilet paper 4 is used up and only the hollow core 42 is left at this time), so that the end of the toilet paper support part 21 away from the rotary connection part 22 can be approximately flush with the part outside the hollow core 42 of the toilet paper 4 so as to rotate the toilet paper support part 21 out of the hollow core 42 of the toilet paper 4, so that the toilet paper 4 is separated from the toilet paper support part 21 in order to remove the toilet paper 4 from the toilet paper access opening 14.
L≤D+2^∗K^∗T, and 0≤K < 1. When K=0, D+2^∗K^∗T is the diameter of the toilet paper 4 after the roll paper 41 is completely used. At this time, the diameter of the toilet paper 4 is the outer diameter of the hollow core 42. When K is 1, D+2^∗K^∗T is the maximum diameter of the toilet paper 4 (that is, the diameter of the toilet paper 4 when it is new and has not been used). When K takes a number greater than or equal to 0 and less than 1, the distance L between the end of the toilet paper support part 21 away from the rotary connection part 22 and the first cavity wall 15 is smaller than the maximum diameter of the toilet paper 4, i.e., smaller than the diameter of unused new toilet paper 4, which can prevent the new toilet paper 4 from completely entering between the toilet paper support part 21 in the access position and the first cavity wall 15, effectively avoiding the possibility of removing the unused new toilet paper 4 in the conventional removal operation, thus achieving the anti-theft purpose.
L≤D+2^∗K^∗T means that the toilet paper 4 can be removed normally when a locking and releasing mechanism is in a lock state only after the toilet paper 4 has been used to a certain extent, that is, after the thickness of the roll paper 41 has been reduced to a certain extent. The unused new toilet paper 4 or the toilet paper 4 with too large diameter after use cannot be removed from the toilet paper holder, which prevents the toilet paper 4 from being stolen.
It should be understood that when K is a positive number less than 1, it should be ensured that L meets L≥T+t and L≥D. That is, when K takes a positive number less than 1 so that L does not meet L≥T+t or L≥D, the value of K is not within the protection scope of the present application.
In some exemplary embodiments, as shown in FIGS. 2-4, the toilet paper access opening 14 is located at the lower part of the toilet paper accommodating cavity 13, and the first cavity wall 15 is the upper cavity wall of the toilet paper accommodating cavity 13.
Alternatively, the toilet paper access opening 14 can be disposed at other locations. If the toilet paper access opening 14 is located on the front side, or left side, or right side, or back side or upper part of the toilet paper accommodating cavity 13, the first cavity wall 15 is correspondingly the rear cavity wall, or right cavity wall, or left cavity wall, or front cavity wall or lower cavity wall of the toilet paper accommodating cavity 13.
In some exemplary embodiments, as shown in FIGS. 2-4, the toilet paper holder 100 further includes a mounting bracket 3 disposed inside the toilet paper accommodating cavity 13, and the mounting bracket 3 is provided with a rotary matching part 31 matched with the rotary connection part 22. One of the rotary matching part 31 and the rotary connection part 22 is a shaft hole, and the other of the rotary matching part 31 and the rotary connection part 22 is a rotating shaft part.
As shown in FIG. 2, the toilet paper bracket 2 is provided with two rotary connection parts 22, and the rotary connection parts 22 are rotating shaft parts. As shown in FIG. 4, the mounting bracket 3 is provided with two rotary matching parts 31, which are shaft holes, and two rotating shaft parts are rotatably inserted into the two shaft holes respectively to achieve the rotatable mounting of the toilet paper bracket 2.
As shown in FIGS. 2-4, the mounting bracket 3 may include a plate-shaped main body provided with two mounting parts 33, and the two mounting parts 33 are fitted with the plate-shaped main body to form two shaft holes. The two mounting parts 33 and the plate-shaped main body may be an integrated structure and formed by stamping; or, the two mounting parts 33 and the plate-shaped main body may be a separated assembly structure. The mounting bracket 3 and the housing 1 are an integrated structure or a separated assembly structure.
In some exemplary embodiments, as shown in FIGS. 2-4, there are two mounting brackets 3, which are respectively located on opposite sides of the toilet paper access opening 14, and the rotary matching parts 31 are provided on the sides of the two mounting brackets 3 facing away from each other. Accordingly, as shown in FIGS. 2-4, there are two toilet paper brackets 2, which are respectively installed on the two mounting brackets 3.
Two mounting brackets 3 and two toilet paper brackets 2 are respectively disposed on the left and right sides of the toilet paper access opening 14 at the lower part. The two toilet paper brackets 2 can support the toilet paper 4 more firmly to make the toilet paper 4 to be firmly installed.
In some exemplary embodiments, as shown in FIGS. 2-4, a limit part 32 is provided within the toilet paper accommodating cavity 13, and the toilet paper bracket 2 is configured to abut against the limit part 32 for limiting when in the support position (see FIG. 3), so as to prevent the toilet paper bracket 2 from rotating towards the toilet paper access opening 14.
When the toilet paper bracket 2 is in the support position, the toilet paper bracket 2 can abut against the limit part 32 for limiting, so as to prevent the toilet paper bracket 2 from rotating towards the lower side where the toilet paper access opening 14 is located, so that the toilet paper bracket 2 can be stably maintained in the support position and stably support the toilet paper 4. In addition, the limit part 32 prevents the toilet paper bracket 2 in the support position from rotating toward the lower side where the toilet paper access opening 14 is located, which can prevent the toilet paper 4 from slipping out of the toilet paper bracket 2 and accidentally falling from the toilet paper access opening 14.
In some exemplary embodiments, as shown in FIGS. 2-4, the limit part 32 is disposed on the mounting bracket 3. A portion of the mounting bracket 3 located between the two mounting parts 33 can form a limit part 32.
Alternatively, the limit part 32 may be provided at other parts except the mounting bracket 3.
In some exemplary embodiments, as shown in FIG. 2, the toilet paper support part 21 of the toilet paper bracket 2 is U-shaped, and two side walls of the toilet paper support part 21 form limit matching parts 23 which abut against the limit part 32. The rotary connection part 22 includes two rotating shaft parts formed by bending ends of two side walls of the toilet paper support part 21.
Correspondingly, as shown in FIG. 4, the rotary matching part 31 includes two shaft holes disposed on the mounting bracket 3 and respectively fitted with the two rotating shaft parts.
The toilet paper bracket 2 is rotatably fitted with two shaft holes of the mounting bracket 3 through two rotating shaft parts, so that the mounting bracket 3 can stably support the toilet paper bracket 2 so as to rotate the toilet paper bracket 2 smoothly.
In some exemplary embodiments, the toilet paper bracket 2 is configured to automatically rotate from the access position to the support position under the action of gravity.
The toilet paper access opening 14 is located at the lower part of the toilet paper accommodating cavity 13. The toilet paper bracket 2 rotates downward when it rotates from the access position to the support position. Therefore, the toilet paper bracket 2 can automatically rotate downward from the access position to the support position under the gravity of the toilet paper bracket 2 and the toilet paper 4.
In some other exemplary embodiments, the toilet paper holder 100 further includes an elastic restoring member, and the toilet paper bracket 2 is automatically held in the support position under the elastic force of the elastic restoring member. The elastic restoring member can be disposed between the toilet paper bracket 2 and the housing 1, or between the toilet paper bracket 2 and the mounting bracket 3. The elastic restoring member can exert elastic force on the toilet paper bracket 2, so that the toilet paper bracket 2 rotates towards the toilet paper access opening 14 so as to automatically rotate the toilet paper bracket 2 from the access position to the support position.
The elastic restoring member may be a spring or an elastic piece. The elastic piece and the mounting bracket 3 may be an integrated structure or a separated assembly structure; or, the elastic piece and the housing 1 may be an integrated structure or a separated assembly structure.
In some exemplary embodiments, as shown in FIG. 2, the housing 1 includes a housing cover 11 and a housing seat 12. The housing cover 11 may be fixed to the housing seat 12. The housing cover 11 may be a front cover fixed on the front side of the housing seat 12. The mounting bracket 3 and the housing seat 12 may be an integrated structure, so as to reduce the number of parts and simplify the structure of the toilet paper holder 100.
The toilet paper holder 100 of the embodiments of the present application will be described below with reference to the drawings.
The toilet paper holder 100 of the embodiments of the present application can allow people to quickly replace the toilet paper 4 and install the toilet paper 4 in the toilet paper holder 100 without any unlocking operation.
The quick replacement of the toilet paper 4 is realized by using two toilet paper brackets 2. The toilet paper brackets 2 can freely rotate upward, but cannot rotate downward beyond initial support position thereof.
During installation, as shown in FIGS. 5 and 6, when the toilet paper 4 is installed into the toilet paper accommodating cavity 13 from below the toilet paper holder 100, the toilet paper 4 pushes the toilet paper brackets 2 to rotate upwards. When the toilet paper bracket 2 rotates to the access position, an end of the toilet paper support part 21 away from the rotary connection part 22 reaches the hollow core 42 of the toilet paper 4, and the toilet paper support part 21 can automatically fall into the hollow core of the toilet paper 4 and return to the initial support position.
When the end of the toilet paper support part 21 away from the rotary connection part 22 reaches the hollow core 42 of the toilet paper 4, and the toilet paper support part 21 automatically falls into the hollow core and returns to the initial support position, the distance between the end of the toilet paper support part 21 away from the rotary connection part 22 and the first cavity wall 15 at the top of the toilet paper holder 100 is just enough to accommodate the standard complete toilet paper 4 (unused new toilet paper 4).
At this time, the complete toilet paper 4 is supported by the toilet paper brackets 2 and installed in the toilet paper holder 100, because the toilet paper brackets 2 in the hollow core 42 of the toilet paper 4 can prevent the toilet paper 4 from being removed from the bottom of the toilet paper holder 100, and the design of the top first cavity wall 15 can also prevent the toilet paper 4 from being removed from the top.
The only way to replace the toilet paper 4 is when the roll paper 41 of the toilet paper 4 is used-up or almost used-up. Only in this case, as shown in FIG. 7, there is enough space to push up the toilet paper 4 and separate the toilet paper 4 from the toilet paper brackets 2 to remove the toilet paper 4.
With the toilet paper holder 100 of the present application, the toilet paper 4 can be quickly replaced and theft can be prevented, which improves the safety and reduces the replacement time.
Although the embodiments disclosed in the present application are as above, the content described is only the embodiments adopted for facilitating the understanding of the present application, and is not intended to limit the present application. Any person skilled in the art to which the present application pertains can make any modifications and changes in the implementation form and details, but the scope of patent protection of the present application shall still be subject to the scope defined in the appended claims.
