Description

Technical Field

[0001] The utility model relates to the technical field of the sealing door of a cleaning and disinfection machine, and particularly relates to a door extrusion type opening and closing door sealing device for a cleaning and disinfection machine. Background Art

[0002] In modern medical, food processing, laboratory and other fields, cleaning and disinfection machines are indispensable equipment for efficiently cleaning and disinfecting various utensils, containers and working environments. However, after long-term use of these devices, the sealing performance of their hatches often becomes one of the key factors affecting the cleaning and disinfection effect. Traditional opening and closing door sealing devices often have problems such as poor sealing, easy wear, and complex operation, resulting in easy leakage of water vapor, chemical substances, etc. during the cleaning and disinfection process, thereby affecting the service life of the equipment and the cleaning and disinfection effect.

[0003] Specifically, traditional sealing methods may rely on simple rubber gaskets or magnetic attraction devices. These methods are prone to sealing failure when the door is opened and closed frequently or under external pressure. In addition, due to the usually high temperature, high pressure and corrosive environment inside the cleaning and disinfection machine, the sealing material is prone to aging and deformation, further exacerbating the problem of sealing performance degradation.

[0004] To solve the above problems and improve the sealing performance and operation convenience of the cleaning and disinfection machine, a new type of door extrusion type opening and closing door sealing device is urgently needed. This device should be able to ensure that the hatch always maintains a good sealing state during the opening and closing of the door, while simplifying the operation process, reducing the maintenance cost, and improving the overall performance and service life of the equipment.

[0010] A number of sets of driving connecting plates are hinged on the side walls of the inner door and the outer door. The inner door is installed on the outer door through the driving connecting plates and vertically moves up and down with the outer door. When the inner door is in the lifting state, the driving connecting plates are in an inclined state. A top frame of the inner door that remains stationary relative to the cleaning and disinfection machine is provided below the inner door. After the bottom surface of the inner door abuts against the top surface of the top frame of the inner door, the driving connecting plates become horizontal and exert pressure on the outer side surface of the inner door, causing the inner side surface of the inner door to abut against the sealing door rubber strip.

[0011] The technical problem to be solved by the present utility model can also be achieved through the following technical solutions. For the above-mentioned door extrusion type opening and closing door sealing device for a cleaning and disinfection machine, three sets of driving connecting plates are provided.

[0027] The following further describes the specific technical solutions of the present utility model with reference to the drawings, so as to facilitate those skilled in the art to further understand the present utility model without limiting its rights.

[0028] Example 1, referring to Figures 1-3 , a door extrusion type opening and closing door sealing device for a cleaning and disinfection machine, the opening and closing door sealing device includes;

[0029] A sealing door rubber strip 1, one side surface of the sealing door rubber strip 1 is fixed on the inner wall of the hatch of the cleaning and disinfection machine, and the other side surface is used to cause the sealing door rubber strip 1 to deform after being pressured, thereby sealing the hatch. The shape of the sealing door rubber strip 1 generally matches the shape of the hatch of the cleaning and disinfection machine;

[0030] An inner door 2, the inner side surface of the inner door 2 faces the sealing door rubber strip 1 to apply pressure to the sealing door rubber strip 1, and the outer side surface of the inner door 2 faces away from the sealing door rubber strip 1;

[0031] The outer door 3 is arranged with its inner side facing the outer side of the inner door 2, thereby exerting pressure on the outer side of the inner door 2. Both the inner door 2 and the outer door 3 are formed into a substantially square plate-like structure;

[0032] A number of groups of driving connecting plates 4 are hinged on the side walls of the inner door 2 and the outer door 3. The driving connecting plates 4 are formed into a substantially plate-like structure. The inner door 2 is installed on the outer door 3 through the driving connecting plates 4 and vertically moves up and down with the outer door 3. When the inner door 2 is in the lifting and lowering state, the driving connecting plates 4 are in an inclined state, and the inclination angle changes with the change of the size of the driving connecting plates 4. Below the inner door 2, there is an inner door top frame 5 that remains stationary relative to the cleaning and disinfection machine. The inner door top frame 5 can be fixed at the hatch of the cleaning and disinfection machine cabin. After the bottom surface of the inner door 2 abuts against the top surface of the inner door top frame 5, the inner door top frame 5 is formed into a substantially square plate-like structure. The driving connecting plates 4 become horizontal and exert pressure on the outer side of the inner door 2, causing the inner side of the inner door 2 to abut against the sealing door rubber strip 1. The sealing door rubber strip 1, the inner door 2, the outer door 3, and the inner door top frame 5 are parallel to each other, and all four are perpendicular to the driving connecting plates 4.

[0033] In Embodiment 1, it should be noted that when the outer door 3 moves vertically downward by an external force, at this time, due to the influence of gravity, the outer side of the inner door 2 fits against the inner side of the outer door 3 and moves vertically downward with the outer door 3. When the bottom wall of the inner door 2 abuts against the inner door top frame 5, since the inner door 2 can no longer move downward, and when the outer door 3 continues to move downward at this time, it will cause the inclined driving connecting plates 4 to change to a horizontal state, so that the inner door 2 moves in a direction away from the outer door 3, and then presses against the sealing door rubber strip 1, finally achieving sealing.

[0034] Embodiment 2, the door extrusion type opening and closing door sealing device for the cleaning and disinfection machine described in Embodiment 1, three groups of driving connecting plates 4 are provided. The three groups of driving connecting plates 4 are respectively located on the top side wall, the middle side wall, and the bottom side wall of the inner door 2 and the outer door 3. Each group of driving connecting plates 4 has two driving connecting plates 4 symmetrically arranged on the left and right side walls of the inner door 2 and the outer door 3.

[0035] In Embodiment 2, the three groups of driving connecting plates 4 can make the connection structure between the inner door 2 and the outer door 3 more stable. The number of groups can be set to multiple groups, and it does not need to be limited to these three groups, and can also be multiple groups.

[0036] Embodiment 2, the door extrusion type opening and closing door sealing device for the cleaning and disinfection machine described in Embodiment 1, the movement trajectory of the outer door 3 is a vertical linear movement;

[0037] The movement trajectory of the inner door 2 when it moves vertically up and down with the outer door 3 and has not abutted against the inner door top frame 5 is a vertical linear movement, and during this period, the driving connecting plates 4 are in an inclined state;

[0038] After the bottom surface of the inner door 2 abuts against the top frame 5 of the inner door, when the outer door 3 continues to descend, the driving connection plate 4 changes from an inclined state to a horizontal state. At this time, the movement trajectory of the outer door 3 changes from a vertical linear movement to a horizontal state.

[0039] When the door extrusion type door sealing device for the cleaning and disinfection machine is in use:

[0040] (1) Installation: First, fix the sealing door rubber strip 1 on the inner wall of the hatch of the cleaning and disinfection machine. Then, fix the top frame 5 of the inner door at a position near the hatch of the cleaning and disinfection machine and below the inner door 2. Then, place the outer door 3 and the inner door 2 at the hatch of the cleaning and disinfection machine. A power mechanism capable of driving the outer door 3 to move up / down can be fixedly connected to the outer door 3, and the outer door 3 is driven to move up and down by this. The driving mechanism can be a cylinder, a hydraulic cylinder, a telescopic electric cylinder, a chain transmission mechanism, a connecting rod transmission mechanism, etc., and is not limited to this. Its purpose is only to drive the outer door 3 to move up / down.

[0041] (2) Use: After installation, there are two states during use, namely the closed state and the open state. When in the closed state, we first move the outer door 3 vertically downward. At this time, due to the gravity of the inner door 2 and the connection effect of the driving connection plate 4 placed between the inner door 2 and the outer door 3, during the vertical descent of the inner door 2 and the outer door 3, the outer side of the inner door 2 will fit against the inner side of the outer door 3. And when the bottom wall of the inner door 2 abuts against the top surface of the top frame 5 of the inner door, if the outer door 3 continues to descend at this time, then the driving connection plate 4 is forced to change from an inclined state to a horizontal state because the inner door 2 cannot continue to descend. As a result, the inner door 2 is forced to move horizontally away from the outer door 3, so that the inner side of the inner door 2 continuously approaches the sealing door rubber strip 1 until the inner side of the inner door 2 is tightly pressed against the hatch of the cleaning and disinfection machine, thereby realizing the sealing of the hatch of the cleaning and disinfection machine.

[0042] When the hatch of the cleaning and disinfection machine needs to be opened, in the reverse order, that is, driving the outer door 3 upward can open the hatch of the cleaning and disinfection machine.
