Abstract
Description
Technical Field
[0001] This utility model relates to the field of public facility supplies technology, and in particular to a double-layer tissue dispenser. Background Technology
[0002] Double-walled tissue dispensers are typically placed in public restrooms and other similar locations to dispense toilet paper. These dispensers usually contain multiple tissue rolls for easy rotation, but they often present some problems in actual use. For example, the tissue rolls inside the dispenser can be easily stolen after it is opened, and in some cases, some used tissue rolls are replaced prematurely, resulting in unnecessary waste.
[0003] Current double-layer tissue dispensers are inadequate in addressing these issues, and a product that can improve upon them is needed. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the ease with which tissue rolls can be stolen and the waste of replacing some tissue rolls, by proposing a double-layer tissue dispenser.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A double-layer paper towel dispenser includes at least two compartments, each compartment comprising:
[0007] At least one base;
[0008] At least one openable cover;
[0009] At least one tissue holder;
[0010] At least one locking device, the locking device comprising:
[0011] At least one tray that moves from an outer position to an inner position when the tissue roll on the tissue holder is used;
[0012] The device includes at least one locking member and at least one unlocking member. When the bracket is in the inner position, at least one unlocking member can engage with at least one locking member. The locking member can be positioned in the locked position, in which the locking member locks the cover closed. The locking member can also be positioned in the unlocked position, in which the locking member does not lock the cover closed.
[0013] In one possible design, a blocking device is also included between the unlocking member and the locking member. When the bracket is in the inner position, the blocking device is pushed to move so that the unlocking member can engage with the locking member. When the bracket is in the outer position, the blocking device is not connected to the bracket.
[0014] When the unlocking component engages with the locking component, the locking component moves to the position of the unlocked cover.
[0015] In one possible design, the locking member also includes a protruding member that engages with the unlocking member when the blocking device is in the second position.
[0016] In one possible design, a button is also included, which is located on the base and engages with a key inserted into a key groove on the top of the cover plate. The unlocking component is connected to the button for moving the unlocking component from the locked position to the unlocked position.
[0017] In one possible design, the locking member also includes a biasing device that biases the locking member to a locked position. The biasing device includes a counterweight acting between a fixed point and a pin located at the distal end of the locking lever.
[0018] One possible design also includes storage doors that slide between compartments.
[0019] In one possible design, the compartment door is equipped with a support arm that engages with one side of the tissue roll on the tissue holder to prevent the compartment door from sliding underneath it.
[0020] In one possible design, the outline of the support arms matches the roll of tissue paper to support it, and they are connected by a spring mechanism to keep them upright and pull them together in the closed position.
[0021] In one possible design, the support arm passes through the entrance of the partition wall between the compartments.
[0022] In this application, during actual use, when a tissue roll is used up, the bracket moves to the inner position, passes through the slot a, and engages with the blocking device to move the blocking device to the second position. When the blocking device is in the second position, the user presses the button to move the unlocking member to a certain position, so that one end of the unlocking member engages with the protruding member of the locking member. The force applied to the unlocking member by the button should be greater than the biasing force of the biasing device. The engagement of the unlocking member with the protruding member of the locking member moves the locking member to a certain position, so that the proximal end separates from the groove of the cover plate, thereby opening the cover plate to replace the tissue roll. Once the tissue roll is replaced, the bracket moves to the outer position, causing the blocking device to move. At the same time, due to the biasing force of the biasing device, the locking member is also in the locked position.
[0023] When the force applied to the button acts on the unlocking component, its force will be greater to overcome the tension of the counterweight acting on the locking component, thereby moving the locking component from the locked position to the unlocked position. Therefore, when the locking component moves to the unlocked position, the cover will open. When the force on the button is released, the counterweight acting on the locking component will cause the locking component to return to the locked position, so that the cover cannot be opened until most or all of the tissue roll has been used, thus preventing the tissue roll from being stolen or wasted by replacing partially used tissue rolls.
[0024] In this utility model, the double-layer tissue dispenser, through the bracket of the locking device, the blocking device and the biasing device, can achieve the effect of preventing the theft of tissue rolls and avoiding the waste of partially used tissue rolls. When the tissue roll is not fully used, the biasing device keeps the locking component biased in the locked position, so that the cover cannot be opened. Only when the tissue roll is mostly or completely used, the bracket moves to the inner position and pushes the blocking device to the second position. At this time, pressing the button can drive the locking component to overcome the biasing force and unlock, ensuring that only the exhausted tissue roll can be replaced, thereby eliminating the problem of theft of unused tissue rolls.
[0025] In this utility model, a double-layer tissue dispenser can achieve the effect of orderly rotation of tissue rolls through a compartment door assembly with a support arm. The outline of the support arm of the compartment door matches the tissue roll and is kept upright by a spring device. Unused tissue rolls will engage with the support arm to prevent the compartment door from sliding. Only when the tissue roll in the current compartment is exhausted can the support arm be rotated open and the compartment door be allowed to slide to the next compartment. This forces the sequential use of tissue rolls in multiple compartments, avoids tissue waste caused by switching compartments in advance, and can also intuitively indicate the location of the compartment that needs to be replenished to the manager.
[0026] In this invention, the mechanical locking mechanism of the locking device only allows unlocking when the tissue roll is exhausted, effectively preventing theft and solving the problem of waste caused by the replacement of partially used tissue rolls. Furthermore, the tissue roll can only be replaced after it has been completely used, thereby extending the continuous paper supply time. Attached Figure Description

Detailed Implementation
[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0043] In one embodiment: Reference Figure 1 and Figure 2 A double-layer tissue dispenser, comprising:
[0044] A double-walled tissue dispenser 100 includes multiple compartments 101, each compartment 101 including a tissue roll holder 102, a base 103, and an openable cover 104. In this embodiment, the dispenser 100 is configured to accommodate a pair of tissue rolls 105, thus including two compartments 101. The bottom edge of the cover 104 is hinged to the base 103, wherein a recess 1041 is located on the top of the cover 104.
[0045] refer to Figure 3-4 The compartment 101 includes a locking device 106 for locking the cover 104. The locking device 106 is used to lock the cover 104 in place when the tissue roll 105 is inside the compartment 101. When the tissue roll 105 has been fully used, the locking device 106 unlocks the compartment 101 to allow for the replenishment of a new tissue roll 105. The tissue roll is located on one side of the base 103, and the locking device 106 is located on the other side of the base 103.
[0046] refer to Figure 5-8 Components of locking device 106, such as Figure 5-6 As shown, the tissue roll 105 is provided with a bracket 107, which can move along the slot 104a on the base 103 to the outer and inner positions. When the tissue roll 105 is full (e.g. Figure 5 As shown), the holder is in the outer position when the tissue roll 105 is exhausted (as shown). Figure 6 As shown), the bracket is located on the inside.
[0047] like Figure 7 As shown, the locking device 106 also includes an unlocking member 108, which moves from the locked position to the unlocked position when the user presses the button 109 on the cover 104, engaging with the blocking device 110. When the tissue roll 105 is not fully used, the blocking device 110 restricts the interaction between the unlocking member 108 and the locking member 111. A spring (not shown) may also be connected to the unlocking member 108 to bias it to the locked position.
[0048] When the bracket 107 is in the outer position, the blocking device 110 will be in a first position, which restricts the engagement of the unlocking member 108 and the locking member 111. When the bracket is in the inner position, the blocking device 110 is forced to move to a second position, in which the blocking device 110 does not restrict the engagement of the unlocking member 108 and the locking member 111.
[0049] In the current embodiment, the blocking device 110 includes a pivot arm that pivots from a first position to a second position when the bracket 107 is in the inner position;
[0050] Referring to the current embodiment, when the bracket 107 is not engaged with the blocking device 110, the pivot arm 1101 is in a first position, hindering the movement of the unlocking member 108. When the bracket 107 is engaged with the blocking device 110, the blocking device 110 moves to a second position, allowing the unlocking member 108 to move. A torsion spring (not shown) is also provided together with the pivot arm so that when the bracket is not engaged with the blocking device 110, the pivot arm naturally moves to the first position.
[0051] When the blocking device 110 is in the second position or the unlocked position, it is necessary to press the button 109 to engage the unlocking member 108 with the locking member 111. Pressing the button 109 can move the device from the external position to the internal position and then reset it to the external position. The button 109 is located on the base 103 and engages with the key 1091 inserted into the key slot 1092.
[0052] like Figure 7-8 As shown, the locking device 106 also includes a locking member 111 for locking the cover plate 104 to the base 103. The locking member 111 can be positioned in a locked position, in which the locking member 111 locks the cover plate 104 closed, and in an unlocked position, in which the locking member 111 does not lock the cover plate 104 closed.
[0053] Locking member 111 includes a proximal end, in the locked position (e.g.) Figure 8 When the proximal end abuts against the groove 1041 of the cover plate 104 (as shown), the locking member 111 also includes a protruding member 1112, which is configured to engage with the unlocking member 108 when the blocking device 110 moves to the second position.
[0054] The locking device 106 also includes a biasing device 112 that naturally biases the locking member 111 to the locked position. In the illustrated embodiment, the biasing device 112 includes a counterweight 113 that acts between the fixing point 114 and the pin 115, which is disposed on the distal end 1113 of the locking member 111. Under the action of gravity, the counterweight biases the locking member 111 to the position where it is locked with the cover plate 104.
[0055] When a tissue roll 105 is used up, the bracket 107 moves to the inner position, passes through the slot 104a, and engages with the blocking device 110 to move the blocking device to a second position. When the blocking device 110 is in the second position, the user presses the button 109 to move the unlocking member 108 to a certain position, so that one end of the unlocking member 108 engages with the protrusion 1112 of the locking member 111. The force applied to the unlocking member 108 by the button 109 should be greater than the biasing force of the biasing device 112. The engagement of the unlocking member 108 with the protrusion 1112 of the locking member 111 moves the locking member 111 to a certain position, so that the proximal end separates from the groove 1041 of the cover plate 104, thereby opening the cover plate 104 to replace the tissue roll 105. Once the tissue roll 105 is replaced, the bracket 107 moves to the outer position, causing the blocking device 110 to move. At the same time, due to the biasing force of the biasing device 112, the locking member 111 is also in the locked position.
[0056] When the force applied to the button 109 acts on the unlocking member 108, its force will be greater to overcome the pulling force of the counterweight 113 acting on the locking member 111, thereby moving the locking member 111 from the locked position to the unlocked position. Therefore, when the locking member 111 moves to the unlocked position, the cover plate 104 will open, and when the force on the button 109 is released, the counterweight 113 acting on the locking member 109 will cause the locking member 109 to return to the locked position.
[0057] This prevents the cover 104 from being opened until the tissue roll 105 is mostly or completely used, thus preventing the tissue roll 105 from being stolen or replaced and wasted. This locking mechanism can be operated individually on each cover 104.
[0058] refer to Figure 12-13 Compartment 101 includes a door 120 that can slide between compartments 101 so that only one tissue roll 105 can be used at a time. The door 120 includes a plurality of arms 122 for engaging with one side of the tissue roll 105 on the tissue roll holder to prevent the door 120 from sliding underneath it.
[0059] Furthermore, when the tissue roll on the other side 105 is not fully or mostly used, the compartment door 120 cannot slide under the tissue roll 105. Only when the tissue roll 105 has been fully used can the compartment door 120 slide under the corresponding tissue roll holder 102.
[0060] The profile of the support arms 122 is designed to support the tissue roll 105. These arms 122 are connected by a spring mechanism to keep them upright and pulled to the closed position. When the tissue roll 105 is fully used and the next tissue roll 105 is needed, the compartment door 120 can be pulled, and one of the support arms 122 on the other side can rotate open and slide under the tissue roll 105. Once the compartment door 120 reaches the desired position, the opened support arm 122 will spring back to the closed position under the action of the spring mechanism. This ensures that the compartment door 120 can easily pass under the tissue roll 105 from any direction after the tissue roll 105 has been fully used, and the support arms 122 can pass through the entrance 123 of the partition wall 124 between the compartments 101.
[0061] This application can be used in the field of public facility supplies, or in other fields applicable to this application.
