Description

Technical Field

[0001] The utility model relates to the field of liquid adding of containers, in particular to the field of liquid adding funnel structure of diaphragm pumps. Background Art

[0002] In the liquid adding scenario, the fluid needs to be poured in from the large opening and eventually enter the liquid storage cavity of the target container. However, in the traditional funnel-type liquid adding tank, after the liquid is added, when the liquid enters the target container, if the liquid adding speed is greater than the liquid discharge speed, the liquid is more likely to fill the liquid adding tank. At this time, the air pressure in the target container has resistance to the inflow of liquid, and the liquid flows in very slowly or stagnates. Not only does it need to constantly adjust the liquid adding speed to adapt to the liquid discharge speed, but there is also the risk of liquid overflow, resulting in low liquid adding efficiency. Utility Model Content

[0003] One purpose of the utility model is to provide a liquid adding structure with higher liquid adding efficiency.

[0004] To achieve the above-mentioned purpose, the liquid adding component is used to add liquid to the liquid storage area in the container, and includes a seat body, an inclined layer, a discharge port and a breathable structure. The seat body is used to dock with the container, and includes a wall body and a chamber; the inclined layer is arranged in the chamber and defines a liquid adding chamber with the wall body; the discharge port is arranged at the low point of the inclined layer, connecting the liquid adding chamber and the liquid storage area; the breathable structure is used to connect the liquid storage area and the atmosphere.

[0005] In one or more embodiments, the breathable structure includes a liquid-isolating wall and air holes, wherein the air holes are arranged on the inclined layer, and the liquid-isolating wall is connected to the wall body and the inclined layer to define an air-permeable cavity isolated from the liquid adding cavity, and the air-permeable cavity is connected to the liquid storage area through the air holes.

[0006] In one or more embodiments, the top of the liquid-isolating wall is arranged flush with the top of the wall body.

[0007] In one or more embodiments, the breathable structure is a ventilation groove arranged on the wall body, the first end of the ventilation groove is located at the top end surface of the wall body, and the second end is located below the inclined layer and connected to the liquid storage area.

[0008] In one or more embodiments, the inclined layer divides the chamber into a liquid adding chamber located above the inclined layer and a docking chamber located below the inclined layer. A separation wall is also provided at the bottom of the inclined layer, and the separation wall divides the docking chamber into a liquid conducting chamber and an isolation chamber. The liquid conducting chamber is connected to the liquid storage area.

[0009] In one or more embodiments, the inclined layer is integrally formed with the wall.

[0010] In one or more embodiments, the seat body includes a docking installation port, and the container provides an external interface that cooperates with the docking installation port.

[0011] In one or more embodiments, the liquid adding component includes at least two air permeable structures and / or two liquid drain ports.

[0012] In one or more embodiments, the inclined layer has an inclination angle of 5° to 35°.

[0013] Another object of the utility model is to provide a diaphragm pump, comprising a housing, a pump core and a liquid storage area located in the housing, wherein the housing is provided with the above-mentioned liquid adding component.

[0044] The present invention is further described below in conjunction with specific embodiments and drawings. More details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the protection scope of the present invention should not be limited by the content of this specific embodiment.

[0045] It should be noted that these and other subsequent drawings are only examples and are not drawn in proportion, and should not be used as a limitation on the actual scope of protection required by the present utility model.

[0046] like Figure 1 and Figure 2As shown, the liquid adding component 10 is used to add liquid to the liquid storage area 101 in the container 100, and includes a seat body 11, an inclined layer 12, a liquid discharge port 13 and a breathable structure 14. The seat body 11 includes a wall body 114 and a chamber 115 surrounded by the wall body 114. The seat body 11 is used to dock with the container 100. For example, in some embodiments, the seat body 11 includes a docking installation port 18, and the container 100 provides an external interface that cooperates with the docking installation port. The interface matching structure of the docking installation port and the external interface includes but is not limited to threaded matching, clearance matching, tight matching, side nail fixing and other structures. Through the interface matching structure, the seat body 11 and the container 100 are detachably connected.

[0047] Continue to refer to Figure 2 As shown, the inclined layer 12 is disposed in the chamber 115 of the seat body 11 and defines a liquid adding chamber 15 with the wall body 114. The inclined layer 12 divides the chamber 115 in the seat body 11 into the liquid adding chamber 15 located above the inclined layer and the docking chamber 17 located below.

[0048] Due to the slope of the inclined layer 12, the bottom of the liquid adding chamber 15 is an inclined surface, and the liquid discharge port 13 is set at the low point of the inclined layer 12, connecting the liquid adding chamber 15 and the liquid storage area 101. The slope structure guides the liquid to flow to the lowest point, promoting the liquid to flow from the liquid discharge port 13 into the liquid storage area 101.

[0049] In some embodiments, the liquid adding structure may further include two or more liquid discharge ports, all of which are arranged at a lower position of the inclined layer 12 .

[0050] Preferably, the inclined layer 12 has an inclination angle of 5° to 35° relative to the plane. Too low an inclination angle is not conducive to the guiding effect of the slope, while too high an inclination angle requires too high a seat height.

[0051] Preferably, the inclined layer 12 is integrally formed with the wall 114 of the seat body 11. For example, the inclined layer 12 and the seat body 11 can be made of polypropylene, polystyrene, or polyvinyl chloride and integrally formed by mold casting.

[0052] In order to avoid the influence of air pressure on the liquid discharge, the liquid adding component 10 of the present invention is also provided with a breathable structure 14 for connecting the liquid storage area 101 and the external atmosphere. The breathable structure 14 can adjust the internal pressure of the liquid discharge area 101 to ensure that the incoming liquid can continuously flow into the liquid storage area 101, and avoid the situation where liquid is retained or blocked at the liquid discharge port 13 due to air pressure. In some embodiments, at least two breathable structures 14 are provided.

[0053] exist Figure 4In a specific embodiment of the breathable structure shown, the breathable structure 14 includes a liquid barrier wall 141 and an air hole 142, the air hole 142 is arranged on the inclined layer 12, the liquid barrier wall 141 is connected to the wall body 114 and the inclined layer 12, and is used to define a breathable cavity 143 isolated from the liquid adding cavity 15, and the breathable cavity 143 is connected to the liquid storage area 101 through the air hole 142.

[0054] Preferably, the top of the liquid-isolating wall 141 is arranged to be flush with the wall body 114 , so that the liquid level is always below the height of the liquid-isolating wall 141 during liquid addition, ensuring that the air-permeable cavity 143 and the liquid-adding cavity 15 are always isolated.

[0055] In another specific embodiment of the breathable structure, the breathable structure is a ventilation groove (not shown in the figure) arranged on the inner wall of the seat body, and the first end of the ventilation groove is located at the top end surface 110 of the wall body 114, and the second end is located below the inclined layer 12 and connected to the liquid storage area 101, so as to keep the liquid storage area 101 always connected to the atmosphere and reduce the impact of the added liquid.

[0056] Therefore, by designing the inclined layer and the drain port, the liquid can be accelerated to enter the target container and the liquid can be discharged quickly; at the same time, the air-permeable structure can be used to promote the continuous flow of the liquid, thereby significantly improving the liquid addition efficiency.

[0057] Reference Figure 2 and Figure 5 As shown, in some embodiments, a partition wall 16 is further provided at the bottom of the inclined layer 12, and the partition wall 16 divides the docking chamber 17 into a liquid conducting chamber 171 and an isolation chamber 172. The liquid conducting chamber 171 is connected to the liquid storage area 101, and it can be understood that the liquid conducting chamber 171 is also connected to the liquid discharge port 13 and the air permeable structure 14. After the seat body 11 and the container 100 are docked, the isolation chamber 172 is docked with the internal structure of the container, so that the isolation chamber 172 is not connected to the liquid storage area 101, and the isolation chamber 172 is not connected to the liquid conducting chamber 171.

[0058] The above design enables the liquid adding component 10 to form two isolated spaces after docking with the container: the liquid discharge port 13, the liquid guiding cavity 171, the air permeable structure 14 and the liquid storage area 101 form the same space; the isolation cavity 172 and the structure inside the container form another space.

[0059] For example, the container is a diaphragm pump, which includes an outer shell 105, a pump core 106 and a liquid storage area 101 located in the outer shell 105, and the pump core 106 is surrounded by an inner shell 107. The inner shell 107 and the pump core 106 are two isolated areas from the liquid storage area 101. After docking with the inner shell, the isolation wall 16 of the liquid adding component 10 continues to isolate the liquid adding area 101 and the non-liquid adding area with the pump core 106, so that the liquid adding flow path is independent to prevent the internal components from being affected.

[0060] In addition to the diaphragm pump, the containers to which the above-mentioned liquid adding component can be applied also include industrial and daily equipment that need to add liquid, such as oil cans and spray devices. The container with the above-mentioned liquid adding component can have a better liquid filling efficiency.

In addition, some features, structures or characteristics in one or more embodiments of the present application can be appropriately combined.
