Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, specifically to an intelligent electric lifting tissue box. Background Technology

[0002] In daily life, tissue boxes are indispensable items in homes and offices. Currently, most tissue boxes on the market have a fixed structure, with a fixed height for the internal space used to hold tissues. When there are many tissues, it is convenient to take them out, but as the tissues are used up, the amount of tissues remaining gradually decreases, and the remaining tissues at the bottom of the tissue box are difficult to retrieve, requiring users to reach deep into the tissue box to find them, resulting in a poor user experience.

[0003] While some tissue boxes feature a manual lifting mechanism, these require manual adjustment by the user, resulting in low levels of automation and cumbersome operation. They also fail to automatically adjust their height based on tissue usage, thus falling short of users' needs for convenient and intelligent household products. Therefore, there is an urgent need for a smart, electrically adjustable tissue box that can automatically adjust its height based on tissue weight while also offering manual adjustment functionality, to solve these problems. Utility Model Content

[0004] To address the problems of existing tissue boxes failing to automatically adjust their height based on tissue usage, resulting in inconvenience in retrieving remaining tissues and low levels of intelligence, this invention provides an intelligent electric lifting tissue box that enables both automatic and manual height adjustment, thereby enhancing the user experience.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent electric lifting tissue box, comprising a tissue box body, a top cover, a lifting mechanism, a movable tray, a gravity sensor, a control module, a power source, two control buttons, and a charging component;

[0006] Furthermore, the top cover can be detachably attached to the top of the tissue box body via a magnetic structure;

[0007] Furthermore, the lifting mechanism is located at the bottom of the tissue box body, the movable tray is horizontally located at the output end of the lifting mechanism for carrying tissues, and the gravity sensor is located between the movable tray and the lifting mechanism for detecting the weight of the tissues on the movable tray.

[0008] Furthermore, the control module includes a single-chip PCB control board and a gravity sensing communication module, wherein the gravity sensor is electrically connected to the single-chip PCB control board through the gravity sensing communication module.

[0009] Furthermore, the power source is a battery, which is electrically connected to a single PCB control board to power the entire device;

[0010] Furthermore, the two control buttons are located on the back of the tissue box body, namely an up button and a down button, and both control buttons are electrically connected to a single PCB control board.

[0011] Furthermore, the charging component includes a charging port, which is a USB Type-C interface, located on the side of the tissue box body. The single-chip PCB control board integrates a battery charging function, and the charging port is electrically connected to the single-chip PCB control board for charging the battery.

[0012] Furthermore, the elevator includes a power source motor and a transmission mechanism. The power source motor is electrically connected to a single PCB control board. The single PCB control board can control the forward and reverse rotation of the power source motor to drive the transmission mechanism to move the moving pallet up or down.

[0013] Furthermore, the single-chip PCB control board is equipped with a current detection module. When the operating current of the power source motor reaches 200mA, the single-chip PCB control board controls the power source motor to stop working. The height of the single-chip PCB control board is limited to within 14mm.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The utility model uses a gravity sensor to detect the weight of the tissues. A single PCB control board controls the lifting mechanism to automatically raise and lower the moving tray based on the weight change, thus realizing automatic adjustment of the tissue box height. When the tissues are placed on the moving tray, the gravity can be detected within 2 seconds and the lifting mechanism can be lowered to the bottom. Afterwards, for every 20g of tissues used, the height automatically rises by 9mm to ensure that the remaining tissues are always at an easy height to take, thus improving the convenience of use.

[0016] It is equipped with a manual control button. When the user feels that the automatically adjusted height is not suitable, they can manually adjust it by pressing the up or down button. Releasing the button will stop the adjustment. After manual adjustment, the automatic lifting data is reset to zero, and the system will automatically adjust again based on the gravity sensor from the moment the manual adjustment stops, thus meeting the user's personalized needs.

[0017] It integrates battery charging functionality, uses a 3.7V rated voltage battery and a USB Type-C charging interface, making charging convenient and providing stable battery life.

[0018] It has a stall protection function, which automatically stops the motor when the operating current reaches 200mA, to avoid damage to the equipment due to overload and extend its service life.

[0019] The overall structure is compact, with the height of a single PCB control board limited to within 14mm, which does not take up too much space and ensures the aesthetics and practicality of the tissue box. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] like Figure 1-4 As shown;

[0030] A smart electric lifting tissue box.

[0031] This implementation plan addresses the technical problems existing in the prior art, such as those disclosed in the background section above: "In daily life, tissue boxes are indispensable items in homes and offices. Currently, most tissue boxes on the market have a fixed structure, with a fixed height for the space inside to hold tissues. When there are many tissues, it is convenient to take them out, but as the tissues are used continuously, the amount of remaining tissues gradually decreases, and the remaining tissues at the bottom of the tissue box are difficult to remove, requiring users to reach deep into the tissue box to search, resulting in a poor user experience."

[0032] Although some tissue boxes are designed with a manual lifting mechanism, they require manual adjustment by the user, have a low level of intelligence, and are cumbersome to operate. They cannot automatically adjust the height according to the amount of tissues used, making it difficult to meet users' needs for convenient and intelligent daily necessities. In terms of practical use, this problem is obviously real and difficult to solve. Therefore, in order to solve this technical problem, an intelligent electric lifting tissue box is provided.

[0033] like Figure 1-4 As shown in the figure;

[0034] This utility model provides a technical solution: an intelligent electric lifting tissue box, including a tissue box body 1, a top cover 2, a lifting mechanism 3, a movable tray 4, a gravity sensor 5, a control module, a power source, two control buttons 6, and a charging component; the top cover 2 is detachably attached to the top of the tissue box body 1 via a magnetic structure; the lifting mechanism 3 is located at the bottom of the tissue box body 1, and the movable tray 4 is horizontally positioned at the output end of the lifting mechanism 3; the gravity sensor 5 is located between the movable tray 4 and the lifting mechanism 3; the control module includes a single-chip PCB control board and a gravity sensing communication module, and the gravity sensor 5 is electrically connected to the single-chip PCB control board through the gravity sensing communication module; the power source is a battery, and the battery... The control panel is electrically connected to a single-chip PCB control board. Two control buttons 6 are located on the back of the tissue box body 1, namely an up button 61 and a down button 62, both electrically connected to the single-chip PCB control board. The charging assembly includes a charging port 7, which is electrically connected to the single-chip PCB control board, which integrates battery charging functionality. The lifting mechanism 3 includes a power source motor, which is electrically connected to the single-chip PCB control board. A current detection module is installed on the single-chip PCB control board; when the operating current of the power source motor reaches 200mA, the single-chip PCB control board controls the power source motor to stop working. The height of the single-chip PCB control board is less than 14mm.

[0035] Charging port 7 is a USB Type-C interface.

[0036] The battery's rated voltage is 3.7V.

[0037] The elevator 3 also includes a transmission mechanism, which is a screw-slider structure. The power source motor drives the screw to rotate, thereby causing the slider and the moving support plate 4 to rise or fall.

[0038] A single PCB control board can control the forward and reverse rotation of the power source motor to drive the moving pallet 4 to rise or fall.

[0039] After the gravity sensor 5 detects that the tissue is placed on the moving tray 4, the single PCB control board controls the elevator 3 to lower the moving tray 4 to the bottom of the tissue box body 1 within 2 seconds.

[0040] The single PCB control board controls the moving tray 4 to rise by 9mm for every 20g decrease in the weight of the tissue detected by the gravity sensor 5.

[0041] When the control button 6 is pressed, the single PCB control board controls the moving tray 4 to rise or fall. When the control button 6 is released, the moving tray 4 stops moving, and the automatic lifting data is reset to zero.

[0042] The working principle of this embodiment is as follows:

[0043] Initial state: When there is no tissue in the tissue box, the moving tray 4 is in the initial position (which can be set to a position close to the top of the elevator 3).

[0044] Placing tissues: Open the top cover 2 and place the new tissues on the movable tray 4. The gravity sensor 5 detects the weight of the tissues and transmits the weight signal to the single-chip PCB control board 61 within 2 seconds. The single-chip PCB control board 61 controls the power source motor 31 to rotate forward (when set to reverse, it drives the movable tray to descend). The drive transmission mechanism 32 drives the movable tray 4 to descend to the bottom of the tissue box body 1.

[0045] Automatic lifting process: As the tissues are used, their weight gradually decreases. Gravity sensor 5 detects the weight change in real time and transmits the data to the single-chip PCB control board 61. According to the preset program, every time the tissue weight decreases by 20g, the single-chip PCB control board 61 controls the power source motor 31 to reverse (set to drive the moving tray to rise when rotating forward), driving the moving tray 4 to rise by 9mm, ensuring that the remaining tissues are always at a height that is easy to access.

[0046] Manual adjustment process: When the user feels that the automatically adjusted height is not suitable, pressing the up button 81 will cause the single-chip PCB control board 61 to receive the signal and control the power source motor 31 to reverse, moving the pallet 4 upward; pressing the down button 82 will control the power source motor 31 to rotate forward, moving the pallet 4 downward. When the button is released, the single-chip PCB control board 61 will stop the power source motor 31 from working, and the automatic lifting data will be reset to zero. From this moment on, the single-chip PCB control board 61 will restart the automatic lifting adjustment based on the weight change detected by the gravity sensor 5.

[0047] Replacing tissues: When the tissues are used up, the moving tray 4 rises to the bottom (near the initial position), the top cover 2 is opened, the empty tissue package is taken out, and a new tissue is put in. After the gravity sensor 5 detects the new weight, the single PCB control board 61 controls the moving tray 4 to descend to the bottom again, and the above usage process is repeated.

[0048] Charging and Protection: When the battery 7 is low on power, it connects to the charging port 9 and an external power source via a USB Type-C charging cable. The charging management chip on the single-chip PCB control board 61 charges the battery 7. During the lifting process, if the power source motor 31 experiences a current of 200mA due to jamming or other reasons, the current detection module detects the signal and transmits it to the single-chip PCB control board 61, controlling the motor to stop working and preventing equipment damage.

[0049] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
