Detailed Description

The invention is described in further detail below with reference to the accompanying examples.

As shown in fig. 1 to 8, the sterilizing cabinet includes:

the cabinet body 1 is a shell of the disinfection cabinet, the prior art can be selected according to needs, and the cross section of the cabinet body in the embodiment is circular and is a cylindrical cabinet body; a doorway 11 is arranged on the side wall of the cabinet body, and an arc-shaped door body 12 is hinged on the doorway 11.

A plurality of trays 2, three in this embodiment, including an upper tray 21 located above, a middle tray 22 located in the middle, and a lower tray 23 located below; wherein the lower tray is connected with the middle tray through a plurality of indirectly arranged connecting rods in a driving way, and the middle tray is connected with the upper tray through a plurality of indirectly arranged connecting rods in a driving way.

The periphery of each tray 2 is provided with a sealing ring 24 which is connected with the inner side wall of the cabinet body in a sealing way, so that the inner cavity of the cabinet body is divided into a plurality of independent spaces, and different sterilization devices can be arranged in different spaces as required to meet different sterilization requirements.

In order to facilitate the rotation of each tray, a sliding groove (not shown in the figure) may be formed on the inner side wall of the cabinet body 1, and the edge of the tray with the sealing ring is accommodated in the sliding groove to reduce the rotation friction force of the tray.

The driving mechanism 5 drives the second transmission component periodically through the first transmission component 3 to drive the lower tray to rotate, so that the middle tray and the upper tray are driven to rotate together. Wherein:

the driving mechanism 5 is arranged below the lower tray 23, is limited relative to the bottom plate of the cabinet body, and comprises a motor 51 and a shifting lever 52; the output shaft of the motor is drivingly connected to the first end of the shift lever 52, and the second end of the shift lever 52 is drivingly connected to the input end of the first transmission assembly 3 through the rotating shaft 53.

The first transmission assembly 3 comprises a fork rod 31 and a support rod 32. Wherein, the fork rod 31 is provided with a slide hole 33 and an open fork groove 34 at intervals along the length direction; the shaft 53 is hinged to a first end of the lever 52 and the fork slot 34 is located at a second end of the fork 31, which is open at a second end edge of the fork.

The two ends of the support rod 31 can be rotatably limited on the central position of the tray 2 and the central position of the bottom plate of the cabinet body through the shaft sleeves 35, and the support rod 31 can be slidably arranged in the sliding hole 33 in a penetrating way. The first transmission component 3 is periodically connected with the second transmission component 4 in a driving way through the fork groove 34.

The second transmission assembly 4 comprises at least two convex columns 41, six in the embodiment, which are arranged on the tray 2 at intervals and are uniformly distributed on a circumferential line with the supporting rod 31 as the center of circle; namely, the six convex columns are uniformly distributed on the circumference which takes the center of the turntable as the center of a circle. Each protruding column 41 is fixed on the lower surface of the lower tray 23, and each protruding column 41 is sequentially accommodated in the fork groove 34 along with the rotation of the fork rod 31, and separated from the fork groove 34 after reciprocating in the fork groove 34.

The interval period of tray rotation can be specified by special dimensional relationships. The following specific design is also made in this embodiment in order to achieve a specified dwell time during the intermittent rotation of the tray.

Setting a motor shaft as a point C, setting a connecting point of a deflector rod and a fork rod, namely the position of a rotating shaft as a point A, setting a supporting rod as a point O and setting a convex column as a point B; the effective length of the deflector rod is the distance AC between the motor shaft and the rotating shaft is a, AO is b; the distance between the convex column and the support rod is OB ═ r.

The length a of the deflector rod and the distance r between the convex column and the supporting rod, namely the center of the turntable are designed values and need to be set manually. R is less than or equal to R, and R is the radius of the tray.

When the slot is just capturing the stud, ∠ CAO is 90 °, ∠ ACO is 60 °, as shown in fig. 4, the actual effective length of the yoke, i.e. the distance from the rotation axis to the second end edge of the yoke, is s ═ b + r ═ AB.

At this time

CO＝2a。

Then

Namely:

the eccentricity of the motor, i.e. the distance OC between the motor shaft and the center of the turntable is 2 multiplied by the length (a) of the shift lever.

In the rotation process, the distance AO of driving lever and fork arm pin joint A to the carousel center is changed, and its length range needs to satisfy: CO-AC is more than or equal to AO and less than or equal to CO + AC, namely a is more than or equal to AO and less than or equal to 3 a.

Therefore, the method comprises the following steps: the length m of the fork rod sliding hole is more than or equal to (3a-a) 2 a;

and if the length of the slide hole of the fork rod and the depth of the fork groove are both minimum values, the rightmost side point of the slide hole is coincided with the deepest point of the slide groove. When the motor rotates 60 degrees clockwise to make the crank and the fork lever coincide, the leftmost point of the slide hole of the fork lever coincides with the center of the rotary disc, and the escapement lever reaches the deepest part of the fork groove, wherein r is m is 2 a.

Therefore r is not less than 2 a.

Therefore, the temperature of the molten metal is controlled,

therefore, the method comprises the following steps:

therefore, R is more than or equal to a and is less than or equal to R, and R is the radius of the tray.

In the design, because the disinfection cabinet body is large, the deflector rod is set to have an original size r which is more than or equal to 2a for avoiding bending and saving labor of a motor and the like. Generally, the convex columns are distributed close to the edge of the cabinet body, preferably R is more than or equal to R and more than or equal to 0.5R, in the embodiment, R is 0.8R, and the length and other key dimensions of the deflector rod a are determined according to the relationship.

When the motor rotates clockwise, the deflector rod rotates one circle along with the output shaft of the motor every time the motor rotates one circle, when the motor drives the deflector rod to rotate to a position vertical to the fork rod, as shown in fig. 4, the fork groove just catches the first convex column 41a, and along with the rotation of the motor, the convex column 41a slides in the fork groove and is driven by the fork rod to rotate, so that the tray is driven to rotate anticlockwise, as shown in fig. 5; after the motor rotates 120 degrees compared with the state shown in fig. 4, at this time, the tray rotates 60 degrees, as shown in fig. 6, the first protruding pillar 41a slides to the open position of the fork groove, and then continues to rotate, the fork groove releases the first protruding pillar 41a, and the motor drives the fork rod to idle through the shift lever, as shown in fig. 7; compared with the state shown in fig. 6, the motor rotates 240 ° to catch the second stud 41b, and enters the state shown in fig. 4. And circulating in sequence.

When the fork rod idles, the tray is in a static state, and at the moment, the ultraviolet lamp (or other sterilization and disinfection devices) in the disinfection cabinet can intensively irradiate (or treat) the articles at the corresponding positions for a period of time so as to obtain good sterilization and disinfection effects; when the fork groove catches the next convex column, the tray is driven to rotate by 60 degrees and then releases the convex column.
