[0038] Please refer to Figure 3 and Figure 4 , specifically, the lock catch assembly includes: a lock catch 5, a torsion spring 6 and an electric spring 4, the lock catch 5 is respectively hinged on both sides of the base 13, the lock catch 5 is long strip-shaped and the cross section is an angle structure, one end is a locking end, the other end is a force receiving end, the torsion spring 6 is two, one end of each torsion spring 6 is connected with the base 13, the other end is wound on the lock catch 5, and the push rod 401 of the electric spring 4 is correspondingly arranged with the force receiving end of the lock catch 5.

[0039] Specifically, the power pulling device 8 is a coil spring.

[0040] Specifically, the side of the clamping block 301 towards the lock catch 5 is formed as an arc structure.

[0041] Specifically, the application sets a control panel, the control panel is electrically connected with the electric spring 4, and the control panel can control the forward and backward movement of the push rod 401 of the electric spring 4.

[0042] Specifically, a mechanical button can be arranged on the control panel, and the user can press the mechanical button to send a signal to the control panel to control the action of the electric spring 4. Preferably, a voice control module or a touch control module can also be arranged on the control panel, and the user can control the action of the electric spring 4 through voice or through the touch control mode.

[0043] Specifically, the application sets a first guide rail 10 on both sides of the base 13, and the length of the first guide rail 10 is consistent with the maximum stroke of the sliding seat 7.

[0045] The locking and opening process of the drawer 3 will be described in detail as follows:

[0046] When the drawer 3 is closed, the user pushes the drawer 3 to move it inside the drawer housing 1, and the second limiting block 302 of the drawer 3 will abut against the rear end wall surface of the sliding seat 7 during the pushing process. At this time, the drawer 3 will drive the sliding seat 7 to move backward at the same time, and the coil spring 8 will be lengthened and unwound during the movement. When the drawer 3 moves to the innermost side of the drawer housing 1, the arc surface of the clamping block 301 will touch the locking end of the lock catch 5, so that the locking end of the lock catch 5 swings counterclockwise to avoid. At this time, the torsional spring 6 is twisted to generate a restoring force. With the continuous movement of the drawer 3 to the rear, the clamping block 301 passes through the locking end of the lock catch 5, and the torsional spring 6 drives the locking end of the lock catch 5 to swing clockwise to reset. After the user releases his hand, the drawer 3 will have a tendency to move forward under the pulling of the coil spring 8, but the drawer 3 cannot move forward under the block of the locking end of the lock catch 5. At this time, the drawer 3 and the sliding seat 7 are locked by the lock catch 5;

[0047] When the drawer 3 is opened, the user only needs to press the opening button on the control panel, and the control panel outputs an instantaneous voltage to the electric spring 4. The electric spring push rod 401 pops out and pushes the force receiving end of the lock catch 5 to swing counterclockwise. At this time, the locking end also swings counterclockwise to disengage from the clamping block 301. In the absence of the clamping effect of the clamping block 301, the coil spring 8 can pull the sliding seat 7 to move forward. Since the drawer 3 is on the sliding seat 7, the sliding seat 7 can also drive the drawer 3 to move forward at the same time. When the sliding seat 7 moves to the maximum stroke position of the first guide rail 10, the sliding seat 7 and the drawer 3 stop moving forward. After that, the user can manually pull the drawer 3, and the drawer 3 continues to move forward on the sliding seat 7. When the second limiting block 302 of the drawer 3 moves to the position where it abuts against the third limiting block 701 of the sliding seat 7, the drawer 3 moves to the maximum stroke. At this time, the drawer 3 is completely opened, and the coil spring 8 is continuously wound during the forward movement of the sliding seat 7 and the drawer 3.

[0048] Specifically, the two side walls of the drawer 3 extend downward for a certain length, so that a certain avoiding space is formed between the bottom surface of the drawer 3 and the sliding seat 7, avoiding the second limiting block 302 of the drawer 3 directly touching the sliding seat 7 during the sliding process.

[0049] Specifically, the coil spring 8 can be symmetrically arranged in multiple numbers and connected with the sliding seat 7 at the same time, so that the sliding seat 7 can be uniformly stressed during the forward movement, avoiding the sliding seat 7 deviating to one side and causing the sliding to be not smooth.

[0050] Please refer to Figure 4Preferably, the application is provided with a rack 9 on the base 13, which extends along the sliding direction of the sliding seat 7. Specifically, a damping gear 14 is provided on the bottom of the sliding seat 7, which is engaged with the rack 9. When the sliding seat 7 slides, the damping gear 14 cooperates with the rack 9 to ensure the directionality of the sliding seat 7. In addition, when the sliding seat 7 is pulled forward by the coil spring 8, the sliding seat 7 can be subjected to a certain resistance, so as to avoid the sliding seat from being impacted by the first limiting block 303 and being damaged when it is pulled forward to the maximum stroke position by the coil spring 8.

[0051] Preferably, the application is provided with a plurality of damping rollers 12 on the base 13, so that when the drawer 3 is pulled, the bottom of the drawer 3 can abut against the damping rollers 12, so as not to be pulled out suddenly. In addition, when the drawer 3 is pushed to move backward to be locked, the damping rollers 12 can control the operating force of the opening and closing of the drawer 3. In addition, under the support of the damping rollers 12, the drawer 3 can also load more and heavier food.

[0052] Further, an inductive device (sensor) can be provided at a predetermined position (the maximum stroke position of the sliding seat 7) of the base 13. The inductive device is electrically connected with the lighting lamp. When the inductive device senses that the sliding seat 7 moves to the maximum stroke position, the inductive device sends a signal to the lighting lamp to control the lighting lamp to be turned on. The user can pull the drawer 3 and take food under the condition of sufficient light.
