Technical Field

The utility model relates to the field of articles for daily use, in particular to a rotary cleaning toothbrush.

Background

The toothbrush is a cleaning tool which combines bristles, a brush head and a handle and has a simple structure. The toothbrush is a cleaning tool necessary for daily life, the development history is long, and the toothbrush can be used as a daily life article for a long time.

However, due to the close arrangement of the toothbrush bristles, the bristles are easily contaminated during use, and it is difficult to clean the contaminated bristles. During the use process, the user can only use the toothbrush for oral cleaning without worry if the toothbrush is clean and sanitary. Therefore, the bristles of a toothbrush must be sufficiently cleaned prior to use to minimize the potential safety hazards of oral problems. There are many toothbrush cleaning devices on the market today, mainly using uv disinfection, vibration of electric toothbrushes, and the use of disposable toothbrushes, etc. However, these methods have the disadvantages of energy problem or waste to some extent, and new innovative ideas need to be proposed to solve the problems.

The Chinese invention patent 213310511 provides a physical method for splitting a toothbrush handle and a toothbrush head into two parts by using a movable rod and a limiting lug, and the two parts can be manually disassembled and replaced with a new toothbrush head after the service life of the toothbrush head is reached, but the disassembled toothbrush head is in a serious pollution state for a long time along with the increase of the use times before the toothbrush head is naturally damaged, and the premature disassembly causes waste and is difficult to meet the product requirements.

The Chinese patent invention 215273513 provides a physical method for modifying the structure of a machine core of an electric toothbrush into a full-buckle structure from a screw structure, so that the problem of internal structure looseness caused by screw looseness caused by shock waves is solved, the upper limit of vibration power of the electric toothbrush is improved to a certain extent, tartar in bristles can be better cleaned by using a vibration effect, but the problem that the tartar is limited by the power supply power and the power supply capacity in the electric toothbrush is limited, and the toothbrush cleaning is limited.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a toothbrush that does not need the electric energy to above problem, and can clear up the brush hair pollution in the at utmost in life.

In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides a rotatory clean toothbrush, includes the toothbrush head, overhead fixedly connected with connecting rod of toothbrush, the one end fixedly connected with toothbrush upper handle that the toothbrush head was kept away from to the connecting rod, handle outside cover is equipped with handle under the toothbrush, and handle inside is hollow structure under the toothbrush, and inside is equipped with the hob, and the cover is equipped with outer ratchet on the hob, and outer ratchet is inside to be equipped with interior ratchet.

As an improvement, the outer ratchet wheel is fixedly connected with the upper handle of the toothbrush.

As an improvement, the upper toothbrush handle and the lower toothbrush handle are in clearance fit, and the shapes of the handles are cylindrical.

As an improvement, the screw rod is arranged at the centroid of the cavity of the lower handle of the toothbrush.

As an improvement, the rotary cleaning toothbrush is matched with a cleaning device, and the diameter of the cleaning device is matched with the outer diameter of the upper handle of the toothbrush.

Compared with the prior art, the utility model the advantage lie in: centrifugal force generated by rotation is used for accelerating the flow of water flow and washing away dirt at the root part by a small amount of manpower, and the increased friction force between the bristles and the tooth cup is used for removing stubborn dirt.

Detailed Description

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

The utility model discloses when concrete implementation, a rotatory clean toothbrush, including toothbrush head 1, fixedly connected with connecting rod 2 on toothbrush head 1, the one end fixedly connected with toothbrush upper handle 3 that toothbrush head 1 was kept away from to connecting rod 2, and 3 outside covers of toothbrush upper handle are equipped with toothbrush lower handle 4, and toothbrush lower handle 4 is inside to be hollow structure, and inside is equipped with hob 5, and the cover is equipped with outer ratchet 6 on the hob 5, and outer ratchet 6 is inside to be equipped with interior ratchet 7.

As an improvement, the outer ratchet wheel 6 is fixedly connected with the upper handle 3 of the toothbrush.

As an improvement, the upper toothbrush handle 3 and the lower toothbrush handle 4 are in clearance fit, and the shapes of the handles are cylindrical.

As a modification, the screw rod 5 is arranged at the centroid of the cavity of the lower handle 4 of the toothbrush.

As an improvement, the rotary cleaning toothbrush is matched with a cleaning device, and the diameter of the cleaning device is matched with the outer diameter of the upper handle 3 of the toothbrush.

The utility model discloses a theory of operation: a toothbrush with a rotatable toothbrush head comprises a toothbrush handle 3, a toothbrush handle 4, a connecting rod 2 and a toothbrush head 1, wherein the bottom of the toothbrush handle 3 is fixedly connected with an outer ratchet wheel 6, a screw rod 5 is arranged in the center of an inner cavity of the toothbrush handle 4, and an inner ratchet wheel 7 is arranged on the screw rod 5 and is in contact with the outer ratchet wheel 6. In the process of pressing or pulling the toothbrush handle 4 downwards or upwards, the screw rod 5 moves downwards or upwards along with the toothbrush handle, so that the inner ratchet wheel 7 is driven to rotate, meanwhile, the outer ratchet wheel 6 in contact with the inner ratchet wheel also rotates along with the inner ratchet wheel, and the outer ratchet wheel 6 drives the toothbrush handle 3 to rotate due to the fixed connection of the toothbrush handle 3 and the outer ratchet wheel 6, so that the toothbrush head 1 is driven to rotate.

When the toothbrush is used, the toothbrush handle 4 is pressed down or pulled up, the toothbrush head 1 is rotated, and therefore water flow is accelerated, and bristles are cleaned up.

(1) A spiral rod is made in the toothbrush rod, a ratchet wheel which can rotate along with the spiral rod is sleeved outside the spiral rod, and an outer ratchet wheel is matched with the ratchet wheel. The outer ratchet wheel can drive the lower part of the toothbrush handle and the toothbrush head to rotate. When the toothbrush handle is pressed downwards, the ratchet wheel drives the outer ratchet wheel to rotate at an accelerated speed, so that the aim of accelerating the toothbrush head is fulfilled. In the process of lifting the toothbrush handle upwards, the rotation direction of the ratchet wheel is reversed, the outer ratchet wheel is separated from the ratchet wheel, and the rotation direction of the outer ratchet wheel cannot be changed, so that the aim of accelerating for many times is fulfilled.

(2) The toothbrush is inserted into the cleaning device with the head of the toothbrush aligned with the slot.

(3) The toothbrush is rotated by pressing the toothbrush and the bristles of the toothbrush rub against the cleaning device to produce a cleaning effect

The toothbrush is first placed in the cleaning device with the head of the toothbrush aligned with the slot of the cleaning device.

The toothbrush head is rotated by manual pressing, so that the toothbrush head and the cleaning device are rubbed to generate a cleaning effect.

The toothbrush is kept dry and stains on the toothbrush are cleaned by friction and rapid rotation of the toothbrush bristles.
