Description

Technical Field

[0001] This utility model relates to the field of cleaning cabinet technology, and more specifically to a cleaning cabinet with an automatically opening door. Background Technology

[0002] Existing cleaning cabinets are typically used for storing and sterilizing tableware, but in practice, users often need to manually open the doors. Currently, the known method for opening cleaning cabinet doors is manual pulling. The opening angle depends on the angle and range of the pull, and for some top-and-bottom opening doors, the door must be pulled a certain distance before gravity forces it open further, failing to achieve a truly convenient opening method. Furthermore, in environments requiring cleanliness and hygiene, manual opening can lead to dirt or bacteria from hands contaminating the cabinet door and tableware inside, negatively impacting the user experience. To meet users' convenience needs and improve the durability and hygiene of the equipment, a cleaning cabinet design that automatically senses a tap signal and opens the door is essential. Through reasonable mechanical design and damping protection, both efficiency and product quality can be improved. Utility Model Content

[0024] A cleaning cabinet with an automatically opening door; please refer to [link / reference]. Figure 1-4The figure includes a cabinet body 100 and a rotatable, openable cabinet door 200 connected to the cabinet body 100. Only the inner shell of the cabinet body 100 and cabinet door 200 is shown in the figure; the outer shell is ignored to fully demonstrate the connection structure of each component. Generally, the cabinet body 100 has a cavity for accommodating tableware and a cleaning and disinfection device for cleaning or disinfecting the tableware. The cabinet body 100 has an opening near the cabinet door 200, which can be closed to seal the internal cavity of the cabinet body 100, ensuring the cleanliness of the tableware. The cabinet door 200 is rotatably connected to the cabinet body 100, and its lower end is connected to the cabinet body 100. The cabinet body 100 is equipped with a sensor that can receive knocking signals, and a push rod ejection mechanism 120 is provided on the cabinet body 100. The push rod ejection mechanism is electrically connected to the sensor and can open and close the cabinet door 200. The cabinet body 100 and cabinet door 200 are connected by a torsion spring assembly and a damping assembly. After the cabinet door 200 is opened, it can be flipped to a set opening angle by the action of the torsion spring assembly and the damping assembly. The cabinet body 100 and cabinet door 200 are equipped with a magnetic attraction assembly that can be magnetically connected. The magnetic attraction assembly is usually composed of two sets of magnets or one set of magnets and one set of magnetic metal. The magnets or magnetic metal are respectively installed on the top of the cabinet door 200 near the cabinet door 200 and on the cabinet body 100 near the cabinet door 200. The positions of the magnets and the magnet / magnetic metal are corresponding. When the cabinet door 200 is closed to the cabinet body 100, the magnetic attraction assembly can keep the cabinet door 200 and the cabinet body 100 in a closed state. In addition, when the cabinet door 200 is close to the closed state, the cabinet door 200 will be attracted and automatically closed due to the magnetic attraction. The principle of this utility model is as follows: after the user taps the cabinet 100, the sensor detects the tapping signal, and the push rod push mechanism 120 is instructed to push open the cabinet door 200. The cabinet door 200 is opened to leave the range of magnetic attraction and is automatically opened by gravity through the action of the torsion spring assembly and the damping assembly.

[0025] Furthermore, the torsion spring assembly includes a torsion spring shaft 310 connecting the cabinet body 100 and the cabinet door 200, and two torsion springs 320 sleeved on the torsion spring shaft 310. The number of torsion springs 320 is not limited to this embodiment. The damping assembly includes a first damper 410 and a second damper 420 disposed on the cabinet body 100. The cabinet door 200 is provided with a shaft fixing part 210 for fixing the torsion spring shaft 310. The spring arm at one end of one of the torsion springs 320 can form a locking position with the shaft fixing part 210. The cabinet door 200 is rotatably connected to the cabinet body 100 through the torsion spring shaft 310. The connection end between the cabinet body 100 and the cabinet door 200 is located below, so the top of the cabinet door 200 can be opened outwards. Two torsion springs 320 are respectively sleeved on the left and right sides of the torsion spring shaft 310. The two torsion springs 320 are located on both sides of the shaft fixing part 210. The torsion spring shaft 310 is fixed on the shaft fixing part 210. The spring arms of the two torsion springs 320 near the shaft fixing part 210 form a hook-like structure. This hook-like structure can be locked with the shaft fixing part 210. The shaft fixing part 210 serves as a support structure for one end of the spring arm of the torsion spring 320. The cabinet door 200 is provided with two connecting buckles 220 that match the torsion springs 320. The spring arm of one end of the torsion spring 320 extends outward and connects with the connecting buckle 220. The spring arm of the torsion spring 320, located away from the pivot fixing part 210, extends towards the top of the cabinet door 200, with the end of the spring arm contacting the outer side of the cabinet door 200. Two connecting buckles 220 are symmetrically arranged, and the connecting buckles 220 have a hook-like structure. The spring arm of the torsion spring 320 is embedded in the connecting buckle 220 to prevent excessive displacement. The two torsion springs 320 work together to provide force, which can prevent the individual structure from deforming or breaking due to long-term stress.

[0026] Furthermore, the first damper 410 and the second damper 420 are respectively connected to the two ends of the torsion spring shaft 310, providing balanced resistance, which slows down the opening and closing speed of the cabinet door 200, reduces collision noise, and extends its service life. The first damper 410 and the second damper 420 are mechanical dampers. In other embodiments, they can be pneumatic dampers or hydraulic dampers. When the cabinet door 200 is pushed open, it can automatically and slowly open under the action of gravity through the first damper 410, the second damper 420, the torsion spring shaft 310, and the cooperating torsion spring 320. The opening angle of the cabinet door 200 can be changed by setting torsion springs 320 with different torque specifications. The greater the torque of the torsion spring 320, the smaller the opening angle of the cabinet door 200. At the same time, a limiting structure can be set on the cabinet body 100 or the cabinet door to limit the opening angle of the cabinet door 200 to meet the usage needs of different users.

[0027] Furthermore, the ejection mechanism 120 includes a motor 121, a push rod plate 122, a push rod 123, and a return spring 124. The push rod 123 is fixed to the top of the cabinet 100 via the push rod plate 122. The motor 121 is connected to the push rod 123 and can drive the push rod 123 to move back and forth. The return spring 124 is sleeved on the push rod 123 and abuts against the cabinet 100 and the push rod plate 122. The return spring 124 can provide output force to reset the push rod 123. The cabinet 100 is provided with an ejection hole 130 through which the push rod 123 can move. When pushed out through the ejection hole 130, the cabinet door 200 can be pushed and opened. The ejection hole 130 is located on the outer edge above the opening of the cabinet body 100. The cabinet body 100 is equipped with a control circuit, which is connected to the push rod ejection mechanism 120 and the sensor. After the sensor receives the knocking signal, it transmits the signal through the control circuit and issues a command to the motor 121. The motor 121 pushes the push rod 123 to move closer to the cabinet door 200. The push rod 123 can move forward stably under the push rod pressure plate 122. The push rod 123 protrudes outward through the ejection hole 130 and pushes open the cabinet door 200.
