Abstract
The utility model provides a wash tooth ware water pump diaphragm connection structure, the diaphragm promotes the connecting rod with the diaphragm and conveniently is connected in solving and washing tooth ware diaphragm pump, improves its life's technical problem, and technical scheme is: a dental irrigator diaphragm pump structure comprising: the diaphragm pump comprises a diaphragm pump water inlet, a diaphragm pump water outlet, a diaphragm pump body, a diaphragm and a diaphragm pushing connecting rod. A connector is arranged between the diaphragm and the diaphragm pushing connecting rod; one end of the connector is hot-melted in the diaphragm sheet to form an integral structure of one end of the connector and the diaphragm sheet, one end of the connector is provided with a spherical connecting cavity, and the diaphragm sheet pushes the ball head at one end of the connecting rod to form a ball head connection capable of rotating relatively with the spherical connecting cavity. The beneficial effects are that: simple structure, small volume, low cost and long service life.
Description
Technical Field
The utility model relates to a water pump structure in medical equipment, in particular to a water pump diaphragm connecting structure of a tooth flushing device.
Background
In the prior art, the tooth flushing device in the medical appliance uses a piston pump, the water pressure is increased in a mode that a piston moves back and forth in a pump body, and a waterproof structure needs to be added to the piston pump to ensure that no water leaks in the machine, so that the size of the machine body is increased. In order to make the product small and exquisite pleasing to the eye, the product among the prior art begins to use diaphragm pump pressure boost mode to add water pressure, and this mode benefit is diaphragm round trip movement and also can be waterproof when adding water pressure to save waterproof construction, reduce towards tooth ware volume, nevertheless because the diaphragm is for having elastic soft gluey class material, joint strength is low easily takes place and the diaphragm promotes the connecting rod pine and takes off, influences life.
SUMMERY OF THE UTILITY MODEL
For solving and promoting the convenient connection of connecting rod with the diaphragm in the tooth ware diaphragm pump, improve its life's technical problem, the utility model discloses a tooth ware water pump diaphragm connection structure washes.
The utility model discloses the technical scheme who realizes that the purpose adopts is: a water pump diaphragm attachment structure for a dental irrigator, comprising: the diaphragm pump comprises a diaphragm pump water inlet, a diaphragm pump water outlet, a diaphragm pump body, a diaphragm and a diaphragm pushing connecting rod.
A connector is arranged between the diaphragm and the diaphragm pushing connecting rod;
one end of the connector is hot-melted in the diaphragm sheet to form an integral structure of one end of the connector and the diaphragm sheet, one end of the connector is provided with a spherical connecting cavity, and the diaphragm sheet pushes the ball head at one end of the connecting rod to form a ball head connection capable of rotating relatively with the spherical connecting cavity.
The utility model has the advantages that: simple structure, small volume, low cost and long service life.
The present invention will be described in detail with reference to the accompanying drawings.
Drawings
Fig. 1 is a schematic view of the cross-sectional structure of the present invention.
In the attached drawing, 1 is a diaphragm, 2 is a diaphragm pushing connecting rod, 3 is a connector, and 3-1 is a spherical connecting cavity. 2-1. bulb, 3-1. spherical connecting cavity, 4. diaphragm pump water inlet, 5. diaphragm pump water outlet, 6 diaphragm pump body.
Detailed Description
Referring to the drawings, a water pump diaphragm attachment structure for a dental irrigator comprises: a diaphragm pump water inlet 4, a diaphragm pump water outlet 5, a diaphragm pump body 6, a diaphragm 1 and a diaphragm pushing connecting rod 2.
A connector 3 is arranged between the diaphragm 1 and the diaphragm pushing connecting rod 2;
one end of the connector 3 is hot-melted in the diaphragm 1 to form an integral structure of one end of the connector 3 and the diaphragm 1, one end of the connector 3 is provided with a spherical connecting cavity 3-1, and the diaphragm pushes the bulb 2-1 at one end of the connecting rod 2 to form a rotatable bulb connection with the spherical connecting cavity 3-1.
One end of the connector 3 is hot-melted in the diaphragm 1 for firm and reliable connection and is not easy to damage.
The ball head 2-1 at one end of the diaphragm pushing connecting rod 2 and the spherical connecting cavity 3-1 form a relatively rotating ball head connection, so that the assembly is convenient, and meanwhile, the universal adjusting function is realized, the action component force of the motion error of the diaphragm pushing connecting rod 2 on the diaphragm 1 is favorably eliminated, and the service life of the diaphragm 1 is greatly prolonged.
During operation, water enters the diaphragm pump body 6 through the diaphragm pump water inlet 4, the diaphragm sheet pushes the connecting rod 2 to do reciprocating linear motion under the driving of the motor and the reduction gear, the diaphragm sheet pushes the connecting rod 2 to drive the diaphragm sheet 1 to elastically deform through the connector 3, the volume in the diaphragm pump body 6 is changed, and the pressure of the increased water is sprayed out through the diaphragm pump water outlet 5.
In the embodiment of the present invention, the connector 3 is an elastic connector. The ball head 2-1 and the spherical connecting cavity 3-1 can be conveniently assembled, and the connection reliability is improved.
In the embodiment of the present invention, the connector 3 is integrated by hot melting when the diaphragm 1 is injection molded. Reduce the manufacturing cost and prolong the service life.
