Description

Technical Field

[0001] The utility model relates to the technical field of glassware cleaning equipment, and particularly relates to an ultrasonic cleaner for cleaning laboratory utensils. Background Art

[0002] Most of the cleaning of colorimetric cuvettes and small test tubes is carried out using ultrasonic cleaning equipment. In existing ultrasonic cleaning, the objects to be cleaned are mostly placed into the cleaning tank, and then the switch is turned on for cleaning operations. For example, Chinese Patent (Application No.: 202022770509.8) discloses a sterilizing ultrasonic cleaning box, which includes a cleaning box body, a stainless steel water tank and a cover plate. The stainless steel water tank is installed in the cleaning box body, and an ultrasonic ceramic vibration transducer is installed inside the stainless steel water tank; one side of the cover plate is movably hinged to the side end of the cleaning box body, and the cover plate is buckled on the upper end of the cleaning box body. A UVC ultraviolet light LED sterilizing lamp is installed inside the cover plate. This sterilizing ultrasonic cleaning box is intelligently controlled by an MCU chip U1. The spring of the touch button is used to turn on and off the machine. Press and hold the touch button for 2 seconds to start working in the small gear of ultrasonic cleaning for 3 minutes and then automatically stop. Press it again to enter the large gear and work for 5 minutes and then automatically stop. Press and hold the touch button for 5 seconds to enter the ultraviolet light sterilization work for 60 seconds and then automatically stop; it has a flip safety protection function. When the lid is opened, the sterilizing lamp automatically turns off to avoid dazzling people's eyes; the overall intelligent control is convenient to use, has high safety and rich functions.

[0003] However, such a cleaning method will cause mutual collision during operation. When the colorimetric cuvette is cleaned, if there is friction or collision on the two narrow surfaces (i.e., the optical glass surfaces), it will directly cause the colorimetric cuvette to be unusable, resulting in an increase in the loss of experimental equipment. Summary of the Utility Model

[0004] In order to solve the above problems, an embodiment of the utility model provides a portable ultrasonic cleaner that can fix the colorimetric cuvette during use.

[0005] In order to achieve the above purpose, an embodiment of the utility model specifically adopts the following technical solution: A portable ultrasonic cleaner includes a housing. A cleaning chamber is arranged in the middle of the housing. An ultrasonic ceramic vibration transducer is arranged at the bottom of the cleaning chamber. A partition plate for fixing the object to be cleaned is arranged in the cleaning chamber.

[0006] As a further improvement of the above technical solution:

[0007] The number of the partition plates is at least two, and a placement gap is reserved between two adjacent partition plates.

[0008] The partition plate is detachably connected to the cleaning chamber, and a plug-in slot is arranged on the side wall of the cleaning chamber.

[0009] A pressing plate is provided at the upper part of the partition plate, and a circulation gap is provided between the lower part and the bottom of the cleaning chamber.

[0010] The pressing plate is placed on two partition plates. A clamping groove is provided at the upper part of the partition plate, and extension plates cooperating with the clamping groove are provided at both ends of the pressing plate.

[0011] A drain port is provided on the side wall of the cleaning chamber.

[0012] A storage battery is provided inside the housing on one side of the cleaning chamber.

[0013] A sealing cover is provided above the cleaning chamber.

[0014] The beneficial effects of the embodiment of the present utility model are as follows: 1. The portable ultrasonic cleaner includes a housing. A cleaning chamber is provided in the middle of the housing. A partition plate for fixing the object to be cleaned is provided in the cleaning chamber. The cleaning chamber is partitioned by the partition plate, so as to fix the position of the colorimetric dish, and prevent the optical glass surface of the colorimetric dish from being damaged due to sliding during the ultrasonic cleaning process, affecting the use in subsequent operations.

[0015] 2. A pressing plate is provided at the upper part of the partition plate. The function of the pressing plate is to limit the upper part of the colorimetric dish, preventing the colorimetric dish from jumping longitudinally under the action of ultrasonic waves during the cleaning process. A circulation gap is provided between the lower part and the bottom of the cleaning chamber. The design of the circulation gap can facilitate the circulation of the cleaning liquid or pure water.

[0021] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0022] As Figures 1-4 shown, the portable ultrasonic cleaner of this embodiment includes a housing 1. A cleaning chamber 2 is provided in the middle of the housing 1. An anti-corrosion coating is provided on the inner side wall of the cleaning chamber 2. An ultrasonic ceramic vibration transducer 3 is provided at the bottom of the cleaning chamber 2. A partition plate 4 for fixing the object to be cleaned is provided in the cleaning chamber 2. The colorimetric cuvette is fixed by the partition plate to prevent the optical glass surface of the colorimetric cuvette from being affected during use due to friction and collision during the cleaning process.

[0023] The number of the partition plates 4 is at least two, and a placement gap 5 is reserved between two adjacent partition plates 4. The colorimetric cuvette is placed in the placement gap 5, and the two partition plates are respectively in contact with the two wide surfaces (i.e., non-optical glass surfaces) of the colorimetric cuvette to fix it.

[0024] The partition plate 4 is detachably connected to the cleaning chamber 2. The position of the partition plate 4 can be selected according to the size of the colorimetric cuvette, and then the width of the placement gap 5 can be adjusted. A plurality of insertion slots 6 are provided on the side wall of the cleaning chamber 2 and are arranged in sequence along the length direction of the cleaning slot. A slope is provided at the bottom of each insertion slot 6 to prevent cleaning liquid or pure water from accumulating in the insertion slot 6.

[0025] A pressing plate 7 is provided on the upper part of the partition plate 4. The function of the pressing plate 7 is to limit the upper part of the colorimetric cuvette to prevent the colorimetric cuvette from jumping longitudinally under the action of ultrasonic waves during the cleaning process. A circulation gap 8 is provided between the lower part and the bottom of the cleaning chamber 2. The design of the circulation gap 8 can facilitate the circulation of cleaning liquid or pure water.

[0026] The pressing plate 7 is placed on the two partition plates 4. A clamping groove 9 is provided on the upper part of the partition plate 4. Extension plates 10 matched with the clamping groove 9 are provided at both ends of the pressing plate 7. The number of the clamping grooves 9 is multiple and is arranged in sequence along the length direction of the partition plate 4.

[0027] A drain port 11 is provided on the side wall of the cleaning chamber 2. The drain port 11 is inclined. It can be externally connected to a drain pipe for drainage, or blocked with a plug and opened when in use.
