Description

Technical Field

[0001] The utility model relates to the technical field of cabinets, in particular to a lifting cabinet trigger control mechanism. Background Art

[0002] As an innovative device in modern kitchens, lift cabinets are designed to optimize storage space and improve the convenience of kitchen use. However, lift cabinets in the prior art have some obvious deficiencies in control methods, especially in the design and operation of control switches.

[0003] At present, the lifting cabinets on the market usually use a separate operating switch to control the lifting of the cabinet. Although this control method can realize the lifting function, it has the following significant disadvantages in actual use:

[0004] 1. Existing lift cabinets require users to operate the control switch separately after closing the cabinet door to realize the lifting function. This means that every time the user uses it, in addition to closing the door, they must also perform an additional switch operation. This not only increases the user's operation steps and affects the convenience of use, but also may cause trouble if the user forgets to operate the switch. For example, the user may need to go back and forth between the cabinet and the control switch many times, wasting time and energy.

[0005] 2. Since the control system and door operation of existing lift cabinets are independent of each other, the user cannot directly trigger the lift operation after closing the door, and must control it through a separate switch. This design cannot achieve the intelligent operation of "close the door and go", making the entire use process not smooth and humane.

[0006] 3. In order to ensure that the lifting operation can only be performed after the cabinet door is closed, the prior art usually requires additional cabinet door safety detection devices. The main function of these detection devices is to detect whether the cabinet door is in a completely closed state to prevent safety hazards caused by misoperation. However, adding detection devices not only complicates the control system structure, but also requires additional installation and debugging, which increases the difficulty of production and maintenance costs.

[0007] 4: Since the existing control system of the lifting cabinet needs to be equipped with independent operating switches and safety detection devices, the overall control system is relatively complex. This not only increases the number of control circuits and hardware, but also increases the manufacturing cost and selling price of the product. In addition, the complex control system also increases the probability of errors during the manufacturing and assembly process, further increasing the production cost and the difficulty of quality control, so it is necessary to make further improvements to it. Utility Model Content

[0008] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a lifting cabinet trigger control mechanism which is simple in structure, easy to use, can simplify the user's operating steps, realize the lifting function of triggering the lifting when the door is closed, reduce the dependence on safety detection devices, thereby reducing production costs and improving the convenience and safety of use.

[0009] The utility model aims to achieve the following: a lifting cabinet trigger control mechanism, which includes a housing installed in the cabinet, a front end of the housing is provided with an air avoidance groove, a trigger button is installed in the housing, and protrudes from the front end surface of the housing through the air avoidance groove and extends into the closing stroke of the cabinet door;

[0010] The trigger button is hingedly installed in the housing, and an elastic reset device is arranged between the trigger button and the housing. The elastic reset device always drives the trigger button outward, so that the trigger button protrudes outward through the air avoidance groove;

[0011] A first trigger switch and a second trigger switch are also installed in the shell, and the trigger heads of the first trigger switch and the second trigger switch extend into the swing stroke of the trigger button.

[0012] Furthermore: the first trigger switch is installed at the front end of the second trigger switch, and when the trigger button is closed inward, the first trigger switch is triggered first, and then the second trigger switch is triggered.

[0013] Furthermore, a rotating shaft is arranged in the shell, a reaming hole is arranged on the trigger button, and the trigger button is swingably mounted on the rotating shaft through the reaming hole.

[0014] Furthermore: the elastic reset device is a torsion spring sleeved on the rotating shaft, one of the supporting legs of the torsion spring is pressed into the shell, and the other end is pressed on the trigger button.

[0015] Furthermore: the elastic reset device also includes a push spring installed on the trigger button. Correspondingly, a baffle is arranged in the shell. When the trigger button is closed, the push spring contacts the baffle to generate a thrust force that pushes the trigger button outward in the opposite direction.

[0016] Furthermore: a spring column is arranged on the trigger button, and the push spring is sleeved on the spring column.

[0017] Furthermore: the first trigger switch is a normally closed switch, and the second trigger switch is a normally open switch.

[0026] The present invention is further described in detail below with reference to the accompanying drawings. A lifting cabinet trigger control mechanism comprises a housing 1 installed in a cabinet body 4, a front end of the housing 1 is provided with an air avoidance groove 2, a trigger button 3 is installed in the housing 1, and protrudes from the front end surface of the housing 1 through the air avoidance groove 2 and extends into the closing stroke of the cabinet door 5;

[0027] The trigger button 3 is hingedly installed in the housing 1, and an elastic reset device is provided between the trigger button 3 and the housing 1. The elastic reset device always drives the trigger button 3 outward, so that the trigger button 3 protrudes outward through the air avoidance groove 2;

[0028] A first trigger switch 6 and a second trigger switch 7 are also installed in the housing 1 . The trigger heads of the first trigger switch 6 and the second trigger switch 7 extend into the swing stroke of the trigger button 3 .

[0029] In one embodiment, the first trigger switch 6 is installed at the front end of the second trigger switch 7. When the trigger button 3 is closed inward, the first trigger switch 6 is triggered first, and then the second trigger switch 7 is triggered.

[0030] In one of the embodiments: a rotating shaft 9 is arranged in the housing 1 , a reaming hole 8 is arranged on the trigger button 3 , and the trigger button 3 is swingably mounted on the rotating shaft 9 through the reaming hole 8 .

[0031] In one of the embodiments, the elastic reset device is a torsion spring 10 mounted on the rotating shaft 9 , one of the supporting legs of the torsion spring 10 is pressed into the housing 1 , and the other end is pressed on the trigger button 3 .

[0032] In one of the embodiments: the elastic reset device also includes a push spring 11 installed on the trigger button 3. Correspondingly, a baffle 12 is provided in the shell 1. When the trigger button 3 is closed, the push spring 11 contacts the baffle 12 to generate a thrust force to push the trigger button 3 outward in the opposite direction.

[0033] In one embodiment, a spring column 13 is disposed on the trigger button 3 , and the push spring 11 is sleeved on the spring column 13 .

[0034] In one embodiment, the first trigger switch 6 is a normally closed switch, and the second trigger switch 7 is a normally open switch.

[0035] In one embodiment, the first trigger switch 6 and the second trigger switch 7 are micro-position switches.

[0036] Working principle: In this case, the trigger button 3 is hingedly installed in the housing 1, protruding from the front end surface of the housing 1 through the air avoidance groove 2 and extending into the closing stroke of the cabinet door 5. The elastic reset device always drives the trigger button 3 outward to keep it in the initial outward protruding state.

[0037] When the cabinet door 5 gradually closes, it pushes the trigger button 3 to swing inward. As the trigger button 3 swings inward, it first triggers the trigger head of the first trigger switch 6, causing the first trigger switch 6 to open if it is a normally closed switch, and close if it is a normally open switch. This generates an electrical signal to the system that the cabinet door has been safely closed. At this point, the control system can control the lifting cabinet to lift upward to reset the cabinet.

[0038] When the cabinet door is closed, when the user presses the cabinet door, the cabinet door continues to push the trigger button 3, further triggering the second trigger switch 7, causing the second trigger switch 7 to operate and generate an electrical signal. The control system controls the cabinet to lift up or drop down according to the current position of the cabinet.

[0039] When the cabinet door 5 is opened, the trigger button 3 loses the external force, and is pushed by the torsion spring of the elastic reset device, and the trigger button automatically resets outward.

[0040] Compared with traditional technologies, this case only needs one trigger button to detect the closing of the cabinet door. If the cabinet door is not closed, the system cannot realize the lifting operation of the lifting cabinet, thereby improving its safety. When the cabinet door is closed, the gap between the cabinet door and the cabinet body is used to press the cabinet door to trigger the lifting of the cabinet body. This device only needs one trigger button to detect the closing of the cabinet door and trigger the lifting control, thereby reducing the number of devices and making the device control logic simpler and more efficient, so it can be widely promoted and used.

[0041] In summary, the lifting cabinet trigger control mechanism of the present invention realizes intelligent detection and precise control of the opening and closing status of the cabinet door, ensuring the safety and reliability of the cabinet during use, while providing a convenient operating experience.

[0042] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
