Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

Embodiment one, as shown in fig. 1, a washer for small-caliber glassware. Comprises a rotor assembly 11 and a brush head 12 arranged on the rotor assembly 11, wherein the rotor assembly 11 and the brush head 12 are common electric devices used for cleaning glassware in the prior art, and the rotor assembly 11 can be assembled by a motor sold in the market and a shell assembly used for installing the motor; the brush head 12 can be a brush commonly used in laboratories for brushing small-diameter glassware such as test tubes and erlenmeyer flasks, for example, a test tube cleaning brush mentioned in the Chinese utility model patent with publication number of CN215879131U and publication date of 2022-02-22. The brush head 12 is connected to the rotary column part of the rotor assembly 11, and the two parts are detachably connected, and the connection and the detachment are also in the prior art, and are not described herein again.

Based on the technical problem discovered by the inventor, namely that the brush is attached to the inner side surface of a glass ware as much as possible when the glass ware is cleaned, the brushing force is enhanced, and the cleaning effect is improved, the simplest solution is that an operator holds the glass ware A to be cleaned by one hand and holds the rotor assembly 11 by the other hand, the motor is started to drive the brush head 12 to rotate, and then the brush head 12 is tightly attached to the glass ware A by force, so that the glass ware can be cleaned. However, this has a number of disadvantages, such as the water used in the cleaning process, the corrosive liquid remaining in the glassware a being spilled on the operator during the cleaning process, and the operator being too tired from the long cleaning job. Therefore, the inventor designs a movable cantilever 2 driven by a pushing unit and a pulling unit, the rotor assembly 11 is fixed by using a clamping piece 202 arranged on the movable cantilever, and the movable cantilever 2 reciprocates left and right under the driving of the pushing unit and the pulling unit to be matched with the rotating effect of a brush head 12, so that glassware A is quickly and highly cleaned.

The working principle of the pushing unit and the pulling unit is as follows:

the pulling unit is composed of a rotating disc 401, a rotating column 402, a winding rope 403, a guide pulley 404 and a rocker 405, wherein the winding rope 403 plays a role in pulling, one end of the winding rope 403 is connected to the end face of the movable cantilever 2 entering the built-in groove 101, the other end of the winding rope 403 is connected to the rotating disc 401, and the connection position is not located at the center of the circle of the rotating disc 401, so that in the rotating process of the rotating disc 401, the distance between the connection point of the movable cantilever 2 connected with the winding rope 403 and the connection point of the rotating disc 401 connected with the winding rope 403 is continuously changed, the length of the winding rope 403 is kept unchanged, and the movable cantilever 2 moves towards the built-in groove 101 through the pulling effect.

In addition, it should be noted that when the distance between the connection point of the movable cantilever 2 connected to the winding rope 403 and the connection point of the rotating disc 401 connected to the winding rope 403 is shortened after the movable cantilever 2 enters the built-in groove 101, the movable cantilever 2 is not reset. At this time, a pushing unit is needed to help the movable cantilever 2 to reset, the pushing unit is composed of a pushing spring 3, one end of the pushing spring 3 is arranged on the groove surface of the built-in groove 101, the other end of the pushing spring jacks up the movable cantilever 2, when the movable cantilever 2 enters the built-in groove 101, the pushing spring 3 is pressed, and under the acting force of the winding rope 403, the elastic potential energy accumulated by the pushing spring 3 cannot be released. When the distance between the connection point of the winding rope 403 on the movable cantilever 2 and the connection point of the rolling rope 403 on the rotating disc 401 is shortened, the tight state of the winding rope 403 is released, so that the limit on the pushing spring 3 is released, the pushing spring 3 releases the elastic potential energy, and the movable cantilever 2 is jacked up to be reset.

Above, be the function place that realizes the reciprocating motion of activity cantilever 2, in order to make this reciprocating motion frequency accelerate, can drive through shaking rocker 405 fast and rotate post 402 to drive rolling disc 401 and rotate, accelerate the distance change frequency between the tie point of connecting rolling rope 403 on the activity cantilever 2 and the tie point that rolling disc 401 links to receive rolling rope 403, thereby realize.

Improvement to the movable cantilever 2:

in the process of reciprocating motion of the movable cantilever 2, the traction force of the pushing spring 3 and the winding rope 403 and the supporting force of the notch of the built-in groove 101 are not enough to well maintain the movable cantilever 2 to move in a horizontal state, the movable cantilever 2 presses down one end of the movable cantilever 2 to incline under the gravity action of the rotor assembly 11 and the brush head 12, and when the inclination degree is too large, the movable cantilever 2 is separated from the built-in groove 101. In order to solve the problem, in the embodiment, a support plate 103 is disposed on the fixed column 1, the support plate 103 extends in the same direction as the movable suspension arm 2, supports the movable suspension arm 2 from bottom to top, and has a length longer than 30% of the movable suspension arm 2 so as to prevent the movable suspension arm 2 from tilting during the reciprocating motion.

In addition, the movable distance is too large and the movable cantilever 2 is directly separated from the built-in groove 101 in the reciprocating motion process, so that a fixed stop part 104 is arranged on the fixed upright post 1, a movable stop part 201 is arranged on the movable cantilever 2, the fixed stop part 104 is a hook part bent towards the movable cantilever 2 and can just catch the movable stop part 201, when the fixed stop part 104 catches the movable stop part 201, the movable cantilever 2 is not separated from the built-in groove 101, and the movable cantilever 2 is limited in motion in the built-in groove 101.

Fixing of glassware a:

in this embodiment, in order to fix the glassware a better, a fixing base 105 is disposed on the bottom surface of the fixing post 1, and a fixing groove 106 is disposed on the fixing base 105, and the size of the groove of the fixing groove is designed for the glassware a, so that the glassware a can be firmly fixed on the fixing base 105, and the brush head 12 is convenient to clean the glassware a.
