[ detailed description ] embodiments
The invention will be further described with reference to the accompanying drawings:
example 1:
as shown in fig. 1 to 2, the present invention provides a pressing assembly, comprising a base 1 connected to a mouth portion of a container, the base 1 is connected with a pressing liquid outlet component 2 which can discharge liquid outwards when sliding relative to the base, the pressing liquid outlet assembly 2 comprises a pressing piece 21 connected to the base 1, the pressing piece 21 is connected with a connecting piece 22 capable of moving relative to the pressing piece 21, a first containing cavity 300 for containing the discharged substances is defined among the connecting piece 22, the pressing piece 21 and the base 1, the pressing piece 21 is provided with a liquid outlet 211 communicated with the first accommodating cavity 300 and used for discharging liquid, an opening and closing assembly 6 which is opened when the pressing piece 21 slides relative to the connecting piece 22 and communicates the liquid outlet 211 with the first accommodating cavity 300 is arranged between the pressing piece 21 and the connecting piece 22, a reset piece 5 capable of driving the connecting piece 22 to reset is further arranged between the pressing piece 21 and the base 1.
When the pressing assembly of the utility model is used, firstly, the pressing piece 21 is operated, the pressing piece 21 moves downwards and pushes the connecting piece 22, at the moment, the connecting piece 22 and the pressing piece 21 are matched to discharge the air in the first accommodating cavity 300 outwards through the liquid outlet 211, and when the pressing piece 21 and the connecting piece 22 move upwards and reset, the air pressure in the first accommodating cavity 300 is smaller than that in the container, so that the substances in the container can be sucked out into the first accommodating cavity 300 for storage, and simultaneously the air in the first accommodating cavity 300 is discharged again, the pressing piece 21 is operated again, the connecting piece 22 pumps the substances in the first accommodating cavity 300 outwards through the liquid outlet 211, and the container is supplemented with air, and the pressing piece 21 is continuously operated, so that the substances in the container can be continuously pumped outwards, the pressing piece 21 is very convenient to use, after the external force applied to the pressing piece 21 is removed, the resetting piece 5 pushes the pressing piece 21 and the connecting piece 22 to rebound and reset, the mode that resets is simple, and each part of pressing the subassembly moreover can adopt unified material to make, is convenient for process production, has reduced the cost of production, because the unity of processing material, it is also more convenient to press the subassembly to retrieve, and more environmental protection compares in the current subassembly of pressing, and this structure of pressing the subassembly is compacter, and the spare part of use also still less, and the workman of being convenient for assembles.
As shown in fig. 1 to 2, the opening and closing assembly 6 includes a communication hole 61 provided on the pressing member 21 for communicating the first receiving chamber 300 with the liquid outlet 211, and a sealing portion 62 provided on the connecting member 22 for closing or opening the communication hole 61 when the pressing member 21 slides relative to the connecting member 22. The sealing portion 62 and the communication hole 61 are used for closing the first accommodating chamber 300 and the liquid outlet 211, so that external dust or particles are prevented from entering the first accommodating chamber 300 and polluting substances in the first accommodating chamber 300. The sealing portion 62 is a sealing plate connected to the pipe body 221. The opening and closing assembly 6 can replace a closed valve, the number of used parts is reduced, the communication hole 61 and the sealing part 62 are common parts and can be processed only when the pressing piece 21 and the connecting piece 22 are molded, additional processing operation is not needed, the production cost is reduced, the material waste is reduced, and the environment-friendly effect is achieved.
As shown in fig. 1 to 2, the connector 22 includes a tube 221, the tube 221 is provided with a transfer passage 222 capable of pumping air into the container when the tube is slid downward and sucking out the contents of the container when the connector 22 is moved upward, the connector 22 is further provided with a drain hole 223 capable of communicating the first housing chamber 300 with the transfer passage 222, and the presser 21 is further provided with a sealing portion 216 capable of sealing the drain hole 223 when the presser slides relative to the connector 22. When the connecting member 22 slides downwards relative to the pressing member 21, the conveying passage 222 can penetrate into the container, so that the substance can rapidly flow into the first accommodating cavity 300, and the substance in the first accommodating cavity 300 remains after being discharged to the liquid outlet 211, so that the liquid can be discharged by slightly pressing the pressing member 21 when the liquid is discharged next time, and the liquid is more convenient to discharge. The pressing piece 21 is provided with a flow passage 400.
As shown in fig. 1 to 2, the reset member 5 includes a closed cavity 51 disposed on the pressing member 21, a pressing portion 52 is disposed in the base 1 and can move in the closed cavity 51 to change the volume of the closed cavity 51, and the volume of the closed cavity 51 increases or decreases so as to generate a pressure difference between the closed cavity 51 and the external atmosphere, wherein the pressure difference can enable the pressing portion 52 to slide and reset when the external force is removed. Because the piece that resets 5 adopts the way that compressed air kick-backs, can avoid metal spring's fatigue, can not appear rust moreover, and then the material in the pollution container.
The working principle is as follows:
