Description

{TEST TUBE CLEANING DEVICE}

The present invention relates to a test tube cleaning apparatus, and more particularly, to a test tube cleaning apparatus capable of automatically cleaning a test tube.

Since the test tube used in the laboratory is formed into a long circular tube shape, it is difficult to clean the inside by inserting a finger or using a hand. The test tube is cleaned using a cleaning brush.

However, since the test tube has a different length and diameter, it was troublesome to change and clean the test tube according to the size of each test tube. Also, since the number of test tubes used in one experiment is at least 50 to 500, it takes much time and effort for the test person to clean the test tubes.

In addition, even if the test person cleans the test tube, since it is a manual operation, it is not easy to clean the foreign substances attached to the inner wall of the test tube.

As shown in the drawing, the test tube cleaning apparatus 100 according to the present invention can selectively use a variety of cleaning brushes 150 corresponding to the diameters R1 and R2 of the test tube A and the length thereof. The tester can select the cleaning brush 150 according to the standard of the test tube A, and then connect the cleaning brush 150 to the lower part of the lifting shaft 120.

The test tube cleaning apparatus 100 includes a main body casing 110 held by a user with one end fixed to the inside of the main casing 110 and the other end exposed to the outside of the main casing 110, And a battery 140 for supplying power to the soccer hoop 130. The hoistway 120 is coupled to the hoistway 120, the hoistway shaft 130 generates a driving force to move the hoistway 120 up and down.

The main body casing 110 is provided in such a size that the user can easily grasp it with one hand. The main body casing 110 is gripped with one hand and the cleaning brush 150 is inserted into the test tube A while the test tube A is being held by the other hand so that the test tube cleaning apparatus 100 is operated.

The main body casing 110 is divided into two independent spaces by the partition walls 116. The main body casing 110 is divided into a driving portion accommodating space 115 and a battery accommodating space 117. The driving shaft accommodating space 115 accommodates the sliding shaft 130 and the battery 140 is accommodated in the battery accommodating space 117.

A lifting and lowering hole 113 is formed through the lower portion of the main casing 110 to expose the lifting shaft 120 to the outside. The main body casing 110 has an input unit 111 for receiving an input signal from the tester. The input unit 111 may be implemented with a plurality of input buttons. The soccer tongue 130 is driven by the input of the input unit 111, and the elevation shaft 120 is moved up and down.

The lifting shaft 120 is lifted up and down by the driving force of the soccer hoop 130. A cleaning brush 150 is detachably coupled to the lower portion of the lifting shaft 120. The cleaning brush 150 includes a coupling shaft 151 and a coupling cap 152 provided at an upper portion of the coupling shaft 151 and coupled to the lifting shaft 120. The cleaning brush 150 is coupled to the outer periphery of the coupling shaft 151, And a cleaning brush 153 for cleaning the cleaning liquid A. The coupling cap 152 is formed such that the lifting shaft 120 is inserted into the interior of the lifting shaft 120 in an interference fit manner.

The lifting shaft 120 is formed to have a constant length. Male threads 121 are formed on the outer circumferential surface of the lifting shaft 120 in a region accommodated in the main casing 110. The male screw thread 121 is threadedly engaged with the female screw thread 134b of the lift shaft support lever 134 to be described later so that the rotary motion of the lift shaft 120 is converted into a vertical movement.

The soccer hoop 130 provides a driving force so that the lifting shaft 120 is moved up and down. 3 is a perspective view showing the configuration of the soccer hoop part 130. As shown in Fig. The soccer leg portion 130 is accommodated in the driving portion accommodating space 115 of the main body casing 110. The soccer hoop 130 includes a driving motor 131 generating a driving force and coupled with an elevation shaft 120 at a lower portion thereof, a motor support shaft 132 coupled to the driving motor 131, A pair of moving rails 133 disposed on the wall in the longitudinal direction and a lifting and lowering support lever 134 for supporting the lifting shaft 120 to move up and down in the lower portion of the moving rail 133.

The drive motor 131 is driven by the power supply of the battery 140 when an input signal of the input unit 111 is applied. An elevating shaft 120 is coupled to a driving shaft (not shown) of the driving motor 131. The motor support shaft 132 is fixedly coupled to the drive motor 131 at an upper portion of the drive motor 131. The motor support shaft 132 is formed in the shape of a bar having a predetermined length, and both ends thereof are coupled to the pair of moving rails 133.

The pair of moving rails 133 and the motor supporting shaft 132 are moved in the LM guide manner. At this time, the upper toggle switch 135 is disposed on the upper portion of the pair of movable rails 133, and the lower toggle switch 137 is disposed on the lower portion. Detection sensors 132a for detecting the toggle switches 135 and 137 are installed at both ends of the motor support shaft 132. [ When the detection sensor 132a detects the lower toggle switch 137, the drive direction of the drive motor 131 is changed to move the motor support shaft 132 upward. When the upper toggle switch 135 is detected, The motor support shaft 132 is moved downward.

In this way, the motor support shaft 132 and the lifting shaft 120 coupled to the drive motor 131 are moved up and down together.

Here, the elevating and lowering shafts 134 are disposed in the lower portion of the moving rail 133 in a direction parallel to the motor supporting shaft 132. A coupling hole 134a through which the elevation shaft 120 passes is formed in the elevation shaft support 134. A female thread 134b corresponding to the male thread 121 of the lifting shaft 120 is formed on the inner circumferential surface of the coupling hole 134a.

When the lifting shaft 120 is rotated by driving the driving motor 131, the male thread 121 and the female thread 134b are engaged with each other and the male thread 121 is moved up or down along the female thread 134b . That is, the rotational motion of the lifting shaft 120 is converted into the up-down motion. At this time, the lifting shaft 120 moves downward or upward according to the driving direction of the driving motor 131.

The battery 140 provides a driving force to the driving motor 131. The battery 140 is connected to a power supply line (not shown) to store power, and supplies power to the driving motor 131. The power supply line (not shown) may be directly connected to the main body casing 110 when the power stored in the battery 140 is insufficient.

The cleaning brushes 150 are provided in a plurality corresponding to the diameters of the various test tubes A used for the test. The tester selects the cleaning brush 150 corresponding to the test tube A and connects the cleaning brush 150 to the lifting shaft 120.

The use procedure of the test tube cleaning apparatus 100 according to the present invention having such a configuration will be described with reference to Figs. 1 to 5. Fig.

A power supply line (not shown) is connected to charge the battery 140 prior to use. When charging is completed, the user holds the main body casing 110 and moves to a place where the washing water is provided, such as a sink. The cleaning brush 150 corresponding to the diameter of the test tube A to be cleaned is coupled to the lower part of the lifting shaft 120. [ The lifting shaft 120 and the cleaning brush 150 are fixed by coupling the coupling cap 152 to the lifting shaft 120.

Then, the cleaning brush 150 is inserted into the test tube A as shown in Fig. The input unit 111 is pressed to apply the input signal. When power is supplied from the battery 140 to the drive motor 131, the lifting shaft 120 is rotated. When the lifting shaft 120 is rotated, the male screw thread 121 and the female screw thread 134b are screwed together and the lifting shaft 120 moves up and down.

The motor support shaft 132 moves along the movement rail 133 in conjunction with the vertical movement of the lifting shaft 120. [ When the motor supporting shaft 132 is moved downward and the lower toggle switch 137 is sensed, the driving direction of the driving motor 131 is changed and the motor supporting shaft 132 is moved upward. When the upper toggle switch 135 is detected, the driving direction of the driving motor 131 is changed again and the motor supporting shaft 132 is moved downward.

When the motor support shaft 132 is moved up and down, the lifting shaft 120 and the cleaning brush 150 move up and down together to clean the inner wall of the test tube A. The cleaning brush 150 moves up and down at a high speed, and the cleaning efficiency is improved because the cleaning brush 150 comes into contact with the wall surface of the test tube A.

At this time, the washing of the test tube (A) can be completed by supplying detergent or the like for washing and washing water in the sink or the like.

6 is an internal configuration of a test tube cleaning apparatus 100a according to another embodiment of the present invention. In the test tube cleaning apparatus 100 according to the preferred embodiment of the present invention, the washing water is supplied from an external device such as a sink. On the other hand, the test tube cleaning apparatus 100 according to another embodiment of the present invention is supplied with wash water from the inside of the main body casing 110.

An independent water storage space 119 is formed in the body casing 110. The water storage space 119 is formed in the lower portion of the drive unit accommodation space 115. The water storage space 119 is formed to communicate with the lifting and lowering hole 113 and discharges the washing water W to the outside through the lifting and lowering hole 113. The washing water W is moved downward along the lifting shaft 120 to be introduced into the test tube A or to the outside of the test tube A. [ Accordingly, the lifting shaft 120 is moved up and down while the washing water W is being supplied, and the test tube A is cleaned. Therefore, the cleaning efficiency can be improved, and the cleaning process can be simplified since no separate water supply is required.

The main body casing 110 is provided with a water transfer path 119a for supplying water to the water storage space 119. A water supply hole 112 for supplying water to the water transfer path 119a is formed in the upper portion of the main casing 110. [ A water supply hose (not shown) is connected to the water supply hole 112 to fill the water. A water supply hose (not shown) is coupled to the water supply hole 112 for the test tube cleaning.

At this time, the water movement path 119a is provided with a water intermittent valve 119b for controlling whether water is supplied or not. The water intermittent valve 119b is opened or closed by a user's input signal. Therefore, the user opens the water intermittent valve 119b when the user desires to supply the washing water, and closes the water intercept valve 119b when the user does not wish to supply the washing water. An input signal to the water intermittent valve 119b can be adjusted by providing a separate button on the input unit 111. [

As described above, in the test tube cleaning apparatus according to the present invention, the cleaning brush moves up and down by the driving force of the driving motor, and the test tube is automatically cleaned. As a result, the cleaning efficiency can be improved and the user's physical load can be reduced

In addition, even when the washing water is supplied together and the supply of the washing water is difficult, the test tube cleaning can be completed with the test tube cleaning apparatus of the present invention.
