Description

Centrifugal mop dehydration device

Technical field

The invention belongs to the field of cleaning tools, and relates to a mop cleaning device, in particular to a device for dehumidifying a mop.

Background technique

Mop as a daily cleaning tool has a high frequency of use in people's lives, but cleaning mops is indeed a dirty work that people do not like. In this regard, people mainly improve the traditional mop from two directions. One is to improve the traditional mop from its own structure, and improve the mop head structure to make it have the function of self-squeezing water, thus avoiding the hand when cleaning the mop. The direct contact of the mop cloth, such as the foam head splint mop that appeared in the market in recent years; the second is to design a special mop cleaning device to replace the traditional mop with mechanical replacement, such as various mop cleaning devices that have appeared on the market. . The function of the mop cleaning device currently on the market is mainly focused on dewatering the mop cloth. The existing mop cleaning device can perform dehydration of the mop cloth in two types: squeeze type and centrifugal type. Compared with squeeze dewatering, centrifugal dewatering is better and is very popular.

In recent years, among various centrifugal mop dehydration devices, a mop dehydration bucket used with a hand-pressed rotary mop has become the first choice because of its simple structure and convenient use. The mop rod of the hand-press rotary mop generally consists of two upper and lower rod bodies, and a unidirectional rotation driving mechanism is arranged therein, and a disc is fixedly arranged at a lower end of the lower rod body, and a plurality of cotton ropes are fixed on the disc. The reciprocating motion of the upper rod relative to the lower rod body in the axial direction can drive the lower rod to drive the disc and the cotton rope to rotate in one direction.

The dewatering bucket used in conjunction with such a mop mainly consists of an outer tub and a spin basket that is rotatable in the outer tub, the bottom and side walls of which are hollowed out.

When using, put the mop head of the rotary mop into the dehydration basket, and straighten the mop rod, repeatedly press down the upper part of the mop rod, under the action of the one-way rotation driving mechanism in the mop rod, the lower part of the mop rod and the mop The head and the dewatering basket rotate together quickly to achieve centrifugal dewatering.

The early dewatering basket has a simple structure, and the force of the hand mop is directly applied to the bottom of the dewatering basket and the indeterminate part of the side wall by the mop cloth. However, the bottom and side walls of the dewatering basket, which are arranged in a hollow structure, have a weak ability to withstand pressure and are easily damaged when subjected to local pressure. In addition, since the rotation of the mop head is achieved under the premise that the dewatering basket supports the mop head, during use, the dewatering basket and the mop head are fastened together, so that the mop head is coaxial with the rotation axis of the dewatering basket. It is necessary, otherwise, it will oscillate or vibrate due to different axes of rotation.

In view of these problems, the existing solution is to provide a supporting positioning column at the bottom of the bottom portion of the dewatering basket, and at the bottom of the disc at the lower end of the mop, a force positioning groove is provided for engaging with the positioning post. When the mop head is placed in the dewatering basket, the force positioning groove is aligned with the support positioning column, so that the support positioning column is inserted into the force positioning groove, and the top of the supporting positioning column cooperates with the bottom surface of the force positioning groove to form a support for the mop. The side of the supporting positioning column cooperates with the side of the force-receiving groove to form a radial limitation of the mop head to achieve the purpose of supporting the mop head and defining the dehydration basket coaxial with the rotating shaft of the mop head.

Although the above method of supporting and defining the axis of rotation of the mop head can achieve a relatively good effect, it still has its limitations. On the one hand, the existing dewatering basket is generally assembled on a main shaft fixed to the outer tub through a movable connecting member such as a bearing provided at the bottom of the dewatering basket, and the supporting point of the main shaft to the dewatering basket is located at the bottom, and the manufacturing process cannot avoid the error. The center of gravity of the dewatering basket cannot just fall on its axis of rotation. When the dewatering basket rotates, there will be a centripetal force relative to the main shaft. The higher the dewatering basket, the greater the distance from the center of gravity to the supporting force point. The greater the moment generated by the centripetal force at the bottom of the dewatering basket, the greater the moment, not only The strength and assembly accuracy of the joints at the bottom of the dewatering basket are higher, and the swinging or vibration of the dewatering basket is more obvious, even because the swing is severe and cannot be used at all. Therefore, the existing dewatering basket is generally designed to have a height of 12 cm or less. It is suitable for household round-head short cotton rope mop with cotton rope length below 12CM. For cotton rope length more than 30CM, it is mainly applicable to large-scale clean round-head cotton mop mops which are suitable for enterprises, institutions and public places. On the other hand, the support positioning columns in the existing dewatering baskets are all short cylindrical structures (cylindrical or prismatic), and the positioning grooves and the positioning positioning columns need to be just aligned to fit the positioning grooves on the positioning support columns. The operation is difficult.

technical problem

The present invention is directed to the problem that the conventional centrifugal mop dehydrator is generally not suitable for a long round mop with a long rope, providing a solution and providing a solution, which can also be conveniently placed on the dehydration. Position the mop head.

Technical solution

In order to achieve the above object, the present invention firstly provides a mop dehydrating device comprising a base and a rotatable dewatering basket, the dewatering basket having an open upper end, a bottom surface and/or a side surface being hollowed out, and an upper end of the dewatering basket. A closed positioning support bushing, the lower end of the sleeve is fixed to the bottom of the dewatering basket, and the upper end is a tapered head. A lower end of the main shaft matched with the inner hole of the sleeve is fixed to the base, and an upper end is inserted into the inner hole of the sleeve by the lower end of the positioning support sleeve, and a top between the upper end of the main shaft and the top surface of the inner hole of the sleeve is provided. The sphere, the height of the top of the tapered head relative to the bottom of the dewatering basket is greater than half the depth of the dewatering basket.

The bushing may be a structure integrally formed with the bottom of the dewatering basket, or may be fixedly assembled by a tight fitting structure after being separately formed and formed. For example, a sleeve integrally formed with the bottom of the dewatering basket is disposed at the center of the bottom of the dewatering basket, and the dewatering basket is fitted to the lower end of the sleeve through a sleeve, and the sleeve is tightly fitted with the sleeve.

The upper end of the sleeve may be a conical head or a pyramidal head. When the conical head is selected, the top may also be designed as a smooth dome structure, that is, the top of the conical head is a spherical structure. And the spherical surface is tangent to the conical surface of the cone at the tip end. The structure of the smooth dome here is such that the mop cotton rope can be smoothly slid from the conical head to the side to solve the problem that the cotton cord can hinder the supporting positioning member from engaging with the positioning groove at the lower end of the mop head.

Further, the upper end of the main shaft is higher than the center of gravity of the dewatering basket. Since the upper end of the spindle is higher than the center of gravity of the dewatering basket, the center of gravity of the dewatering basket is located on the main shaft (not above the main shaft). When the mop is dehydrated, the rotation centripetal force of the dewatering basket (the machining error causes the center of gravity of the dewatering basket to deviate from the spindle axis) acts directly on the main shaft. No torque is generated between the sleeve and the spindle, and the stability is greatly improved.

As an improvement, in order to prevent the dewatering basket from easily slipping upward from the main shaft, a ring groove or a convex ring structure may be arranged in the sleeve, and a matching convex ring or ring groove structure is arranged on the main shaft.

As an improvement, in order to more reliably prevent the dewatering basket from easily slipping upward from the main shaft, it is also possible to design a relatively complicated but stable and reliable limit structure, for example, a connection is provided at the bottom of the dewatering basket or at the lower opening of the sleeve. A limiting member is fixed under the corresponding connecting head on the main shaft, and a connecting member below the limiting member is movably fitted on the main shaft, and the connecting member is connected with the connecting head. This structure reliably prevents the dewatering basket from slipping upwards from the main shaft by a reliable connection between the connector and the connector.

The connecting head may be an annular interface, and a limiting clip spring is fixedly mounted on the main shaft as the limiting member under the annular interface, and a slotted connecting sleeve with a hole in the middle of the limiting sleeve is movablely disposed. On the main shaft, the inner diameter of the side wall of the connecting sleeve is larger than the limit retaining spring, and the upper opening of the side wall of the connecting sleeve and the annular interface are cooperatively connected by a connecting structure such as a thread and a bayonet.

This improvement scheme restricts the upward movement of the connecting member by the limiting member, and the dewatering basket is restricted from being moved upward by the limiting member as the connecting member is connected with the connecting portion of the lower opening of the sleeve.

Beneficial effect

In one aspect of the invention, the dewatering basket is arranged on the main shaft through the shaft assembly. Compared with the bearing, the structure is not only simple in structure, but also convenient to install, and the contact surface between the sleeve and the main shaft is large, which can effectively prevent the dewatering basket from swinging. On the other hand, the bushing has the function of positioning support, and there is no need to separately set the positioning support column, which reduces the number of parts and effectively reduces the cost. Moreover, the upper end of the sleeve is a tapered head structure, which is used in combination with a mop with a tapered groove at the lower end of the mandrel, which is convenient for positioning the mop during dehydration. In the third aspect, the support point of the main shaft to the dewatering basket is located at the top surface of the inner hole of the sleeve, close to the upper end of the sleeve, and is closer to the center of gravity of the dewatering basket than the bottom of the dewatering basket, and the rotational centripetal force of the dewatering basket is generated at the fulcrum. The torque is effectively reduced, which has a significant effect in preventing the swing basket from vibrating or vibrating, and also reduces the strength requirement at the bottom of the dewatering basket. It is possible to design a taller dewatering basket for a thicker and longer mop. In the fourth aspect, the height of the sleeve which is used for positioning support is relatively high, and is more suitable for a long round mop with a long cotton cord. When the dewatering basket is designed by using the structure, the height of the dewatering basket can be freely designed according to the length of the mop. Dimensions, as long as the sleeve and spindle length are properly designed. Basically, it is guaranteed to stabilize when the dewatering basket rotates.
