[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0026] like Figure 1 As shown, an automatic door lock structure for a bottle washer is provided on the bottle washer and includes a door lock base 2, a self-locking motor 3, a gear transmission transition assembly, a gear output, and an unlocking assembly. The self-locking motor 3, the gear transmission transition assembly, the gear output, and the unlocking assembly are all provided on the door lock base 2.

[0027] The self-locking motor 3 serves as a power driving source for the automatic door lock. Preferably, the self-locking motor 3 is a worm gear self-locking motor 3 .

[0028] The self-locking motor 3 is connected to the gear output and the unlocking component through the gear transmission transition component. As a transmission transition module, the gear transmission transition component not only plays the role of transmission, but also plays the role of adjusting the unlocking speed of the door lock.

[0029] In one possible embodiment, the gear transmission transition assembly includes an output gear 4, an intermediate gear 5 and a first gear shaft 6, and the gear output and unlocking assembly includes a second gear shaft 9, a spring 7, a door lock rod 1 and an unlocking link 8.

[0030] Specifically, the output shaft of the self-locking motor 3 is transmission-connected with the output gear 4, and the output gear 4, the intermediate gear 5 and the first gear shaft 6 are arranged in parallel and side by side, and each pair of adjacent gears are meshed and transmission-connected with each other, that is, the three gears are arranged in parallel along the parallel direction of the output shaft of the self-locking motor 3, and the output gear 4 is meshed and connected to the intermediate gear 5, and the intermediate gear 5 is meshed and connected to the first gear shaft 6.

[0031] The second gear shaft 9 is arranged along the length direction of the first gear shaft 6, and the first gear shaft 6 and the second gear shaft 9 are connected by a clutch disc tooth meshing connection, that is, the ends of the first gear shaft 6 and the second gear shaft 9 that are close to each other are provided with clutch disc teeth that work together, and the clutch between the first gear shaft 6 and the second gear shaft 9 is realized through the clutch disc teeth.

[0032] The door lock rod 1 is arranged in a direction perpendicular to the second gear shaft 9. A rack is provided on the door lock rod 1. The rack is arranged along the length direction of the door lock rod 1. The door lock rod 1 is meshed and connected with the second gear shaft 9 through the rack.

[0033] The self-locking motor 3 drives the door lock rod 1 to work to achieve automatic unlocking. The process is as follows: the self-locking motor 3 starts, drives the output gear 4 to rotate, and drives the first gear shaft 6 to rotate through the transmission of the intermediate gear 5. At this time, the first gear shaft 6 and the second gear shaft 9 are in a meshing connection state. The second gear shaft 9 rotates and is transmitted to the door lock rod 1 under the meshing action of the second gear shaft 9 and the door lock rod 1, thereby realizing the forward and reverse rotation of the door lock rod 1, and automatic unlocking and unlocking can be achieved.

[0034] Here, firstly, due to the setting of the self-locking motor 3, the door lock can be self-locked at any position during the process of unlocking and unlocking, and can be self-locked when the power is off, thereby expanding its applicability.

[0035] In addition, the gear transition assembly adopts a two-stage transmission ratio, and the gear teeth reduction ratio can be adjusted as needed to adjust the moving speed of the door lock rod 1, thereby adjusting the unlocking speed of the door lock.

[0036] The automatic door lock structure of the present invention can not only realize automatic unlocking, but also enable emergency opening of the door lock when the motor cannot operate, so that the door lock rod 1 can be taken out and put in separately when the power is off. In view of this, the present application also proposes the following structure:

[0037] Specifically, a spring 7 is sleeved on one end of the first gear shaft 6 away from the second gear shaft 9. Under the action of the spring 7, the first gear shaft 6 and the second gear shaft 9 are meshed together. In addition, an unlocking link 8 is connected to this end. The unlocking link 8 is twistable, and the other end of the unlocking link 8 extends to the unlocking hole. Preferably, the unlocking link 8 is rotatably connected to the door lock bottom housing 2 via a rotating shaft. In addition, the unlocking link 8 is tilted relative to the first gear shaft 6, and the rotating shaft is located on the unlocking link 8 near the end of the first gear shaft 6. In this way, it can be more labor-saving when twisting the unlocking link 8.

[0038] When the self-locking motor 3 cannot run, the door lock is powered off and unlocked, as shown in the following example: Figure 2-4 As shown: the unlocking tool 10 is pushed toward the unlocking hole (the unlocking tool 10 in the figure is only a schematic diagram, and its structure is not limited to the figure. The unlocking tool 10 can be any rod or screwdriver with a diameter less than 6 mm, etc., so that any unlocking tool 10 can be used to unlock). The unlocking tool 10 pushes the unlocking link 8, and the unlocking link 8 twists, driving the first gear shaft 6 to move to the right. At this time, the clutch disc teeth of the first gear shaft 6 and the second gear shaft 9 are disengaged, and the door lock rod 1 can move freely along the transmission direction, and emergency door opening can be achieved; remove the unlocking tool 10, and the first gear shaft 6 resumes meshing with the second gear shaft 9 under the elastic action of the spring 7.

[0039] By setting the gear output and this part of the structure in the unlocking assembly, emergency door opening and restoration of engagement of the door lock rod 1 are achieved.

[0040] In addition, setting the output gear 4, the intermediate gear 5 and the first gear shaft 6 as a direct connection structure arranged in parallel can facilitate the first gear shaft 6 to slide left and right in the horizontal direction, thereby facilitating the conversion of the first gear shaft 6 and the second gear shaft 9 into and out of engagement.

[0041] The clutch disc teeth used between the first gear shaft 6 and the second gear shaft 9 are configured as beveled teeth. The beveled teeth arrangement allows the door lock lever 1 to be pushed in the opposite direction of the pull-out direction after emergency door opening, without disassembling or assembling anything, while the first gear shaft 6 and the second gear shaft 9 are in meshing state.

[0042] Furthermore, to ensure that the unlocking link 8 can properly drive the first gear shaft 6 in the opposite horizontal direction, a C-notch is formed on the end of the unlocking link 8 that connects to the first gear shaft 6; an annular notch that cooperates with the C-notch is formed on the end of the first gear shaft 6 that is closer to the unlocking link 8. Thus, the C-notch of the unlocking link 8 fits within the annular notch, allowing the first gear shaft 6 to move left and right without affecting its rotation.

[0043] The specific implementation principle of the present invention is: when automatically unlocking and unlocking, the self-locking motor 3 is started, transmitted to the second gear shaft 9 through the gear transmission transition zone, and then transmitted to the door lock rod 1 to realize the forward and reverse rotation of the door lock railing, that is, to realize automatic unlocking and unlocking of the door lock; in the case of power failure, the unlocking tool 10 pushes the unlocking connecting rod 8 and transmits it to the first gear shaft 6, so that the first gear shaft 6 is disengaged from the second gear shaft 9, and the door lock railing can move freely along the transmission direction, thereby realizing emergency door opening; when restoring self-locking, the unlocking tool 10 is removed, and the first gear shaft 6 is restored to mesh with the second gear shaft 9 under the action of the spring 7.

[0044] The entire bottle washing machine has an automatic unlocking structure and a door lock structure with low torque; the speed of the door lock rod 1 can be adjusted as needed; the door lock can be self-locked when the power is cut off after being closed; if the motor cannot run, the door lock can be opened urgently after self-locking; the door lock rod 1 can be taken out and put in separately when the power is cut off.

[0045] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
