Description

Ultrasonic generator connection structure, cleaning device and wine aging device

Technical field

The utility model relates to an ultrasonic cleaning or aging device, in particular to an ultrasonic generator connection structure, a cleaning device and a wine aging device.

Background technique

Ultrasonic has been widely recognized in the cleaning field, and it has been widely used in more and more fields. At the same time, the discovery of important help for the aging of wine products, so the application field of wine aging has gradually expanded. Ultrasonic generator is the most core component of these equipment, so whether these ultrasonic generators can work normally determines the service life of the equipment to a certain extent. Regardless of the application in the cleaning field or the wine aging field, the principle is: the ultrasonic generator is fixed under the stainless steel cylinder or tank, the ultrasonic generator is driven by the circuit to generate ultrasonic waves, and the ultrasonic waves drive the bottom of the stainless steel cylinder to conduct Go to the water body in the stainless steel cylinder to realize ultrasonic cleaning of items or ageing of wine. Figure 1 is an exploded view of the ultrasonic generator, and Figure 2 is an overall cross-sectional view of the ultrasonic generator. The ultrasonic generator mainly includes a bolt 6, a back cover 5, an insulating sleeve 7 made of silica gel or tetrafluoroethylene, a first transducer sheet 8, a second transducer sheet 10, a positive electrode sheet 9, a negative electrode sheet 4 and a front cover 3. The rear cover 5, the first transducer element 8, the second transducer element 10, the positive electrode sheet 9, the negative electrode sheet 4 and the front cover 3 are all provided with through holes matching the bolts 6, and the insulating sleeve 7 covers at least the first Transducer piece 8, second transducer piece 10, positive electrode piece 9 and negative electrode piece 4, holding bolt 6 and first transducer piece 8, second transducer piece 10, positive electrode piece 9 and negative electrode piece 4 Insulate between; the back cover 5, the insulating sleeve 7, the first transducer sheet 8, the positive electrode sheet 9, the second transducer sheet 10, the negative electrode sheet 4 and the front cover 3 are connected in order by bolts. The upper surface of the front cover 3 is a smooth round surface. If the front cover 3 is directly attached to the bottom of the stainless steel cylinder 1 with glue, the following problems may be caused: the cylinder and the added water on the cylinder will form The load is directly superimposed on the ultrasonic generator, which is easy to cause the problem of sensitivity to the load of the ultrasonic generator, causing the problem of drift and jitter of the ultrasonic frequency, and then causing the problem of heat; at the same time, direct contact also has certain safety risks. In order to solve this problem, it is necessary to directly add an insulating sheet 12 between the stainless steel cylinder and the ultrasonic generator. FIG. 3 is a schematic diagram of the connection structure of the existing ultrasonic generator. The insulating sheet is slightly larger than the end surface of the front cover 3. Therefore, the existing design method of fixing the ultrasonic generator is to use glue to bond the insulating sheet 12 and the ultrasonic generator, and then the insulating sheet is crimped to the bottom of the stainless steel cylinder through the glue. This connection process requires the stainless steel cylinder. The flatness of the connecting part is very high. In order to ensure its flatness, it is necessary to additionally press a circular concave surface 13 on the part where the ultrasonic generator is installed, because the flatness of the small area is easier to achieve. Adhesive bonding is achieved through viscose, which brings about new problems. The viscose tends to become brittle and lose its viscosity at high temperatures, which causes the problem of the ultrasonic generator falling off, which is commonly referred to as the problem of turning around. The ultrasonic generator has the problem of heating when it is working, and the insulating sheet added between the ultrasonic generator and the stainless steel cylinder also prevents the heat transfer of the ultrasonic generator to the stainless steel cylinder to a certain extent. Therefore, in order to prevent the temperature of the viscose from exceeding its safe use range, the equipment needs to monitor the temperature of the ultrasonic generator, and control the ultrasonic generator to shut down after working for a period of time until the temperature drops to a certain level before continuing to work. Specific to the application of wine aging, it is impossible to achieve long-term continuous aging due to temperature rise.

In order to increase the cleaning speed or shorten the wine aging time, it is necessary to increase the power of the ultrasonic generator. As the power of the ultrasonic generator increases, its size, weight, and calorific value also increase. If the original connection method is used, The problem of the ultrasonic generator falling off will be more serious, and the increase in heat generation will inevitably limit its continuous working time.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, not all implementations. example. Based on the embodiments of the present utility model, all other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

Figure 4 is a schematic diagram of the structure of the ultrasonic generator connected with an aluminum sheet. The improvement of this technical solution is to replace the insulating sheet conventionally arranged between the ultrasonic generator and the stainless steel cylinder with aluminum sheet 2, and at the same time enlarge the aluminum sheet diameter. The technical effects brought about by replacing the insulating sheet with aluminum sheet are mainly reflected in the following aspects:

1. The ultrasonic generator, aluminum sheet and stainless steel cylinder are all metal materials, so the materials are close; and if the insulating sheet is used, the material difference is large, so the bonding effect is worse. In particular, the material of the front cover 3 connecting the ultrasonic generator and the aluminum sheet is generally also aluminum material, so the material is the same as the aluminum sheet, and the connection effect is better.

2. Compared with the insulating sheet, the area of the aluminum sheet is enlarged, and the connection area between the aluminum sheet and the stainless steel cylinder is increased. As the connection area is increased, the bonding strength is strengthened; therefore, to a certain extent, the stainless steel cylinder and the aluminum The flatness of the connection surface between the sheets does not need to be as high as the connection method of the insulating sheet, so there is no need to install an ultrasonic generator according to the size of the microwave generator in order to ensure the flatness of the connection surface as in the existing design. The round concave surface of the device, so the process is more simplified.

3. Enlarging the area of the aluminum sheet also brings another technical effect that makes the ultrasonic distribution more uniform, while the existing design has the ultrasonic intensity concentrated directly above the ultrasonic generator, and other areas are quite weak.

4. Compared with the insulating sheet, the aluminum sheet has better thermal conductivity. The heat generated by the ultrasonic generator can be quickly conducted into the stainless steel cylinder through the aluminum sheet, which is equivalent to that the entire stainless steel cylinder is the heat sink of the ultrasonic generator. The heat generated by the ultrasonic generator is quickly dissipated, keeping the temperature of the ultrasonic generator within a safe range. Because the temperature of continuous working for a long time can be controlled within a safe range, long-term continuous wine aging can be realized. Compared with the previous period of work, the overall aging time has been greatly shortened.

The following compares the effects of two specific embodiments:

Specific implementation 1: The ultrasonic generator is connected by means of an insulating sheet; due to the temperature rise, a high-power ultrasonic generator cannot be used, and only a 60W power ultrasonic generator can be selected. The weight of the ultrasonic generator is about 280 grams , The aging process needs to be stopped to dissipate heat, so it takes about 6 hours to age a bottle of wine; and the device has a higher probability of turning around.

Specific implementation 2: The ultrasonic generator is connected with an enlarged aluminum sheet instead of an insulating sheet; in order to increase the intensity of the ultrasonic wave, a 90W ultrasonic generator is selected, and the area of the aluminum sheet is expanded to the end face of the front cover of the ultrasonic generator 1.5 times. Since the aluminum sheet has a good heat dissipation effect, the problem of excessive temperature will not occur after long-term continuous work, so the time ratio between work and shutdown can be greatly improved. On the whole, after the overall power is increased, it only takes about 3 hours to age the wine of the same specification to the same degree compared to Scheme 1, so the efficiency is greatly improved.

What is disclosed above is only an embodiment of the present utility model. Of course, it cannot be used to limit the scope of the rights. A person of ordinary skill in the art can understand all or part of the process for realizing the above-mentioned embodiments and follow the claims of the present utility model. The equivalent change of is still within the scope of the utility model.
