Description

Diaphragm water pump that leakproofness is good

Technical Field

The utility model belongs to the technical field of diaphragm water pumps, and particularly relates to a diaphragm water pump with good sealing performance.

Background

The diaphragm pump is also called a control pump, is a main type of an actuator, a group of diaphragms are arranged on a sealing cover of the diaphragm pump, and a sealing ring is also arranged at the connecting position of the sealing cover and a pump body, so that the tightness of the water pump is ensured; in order to install the sealing ring, a groove body (a filling area shown in fig. 1) is formed in the existing pump body and the pump cover, the sealing ring is arranged in the groove body, and the sealing ring fully fills the groove body under the action of pressure, so that the sealing of the water pump is realized.

However, in the actual use state, as the sealing ring is made of soft materials such as rubber or resin, and the groove body of the sealing cover is generally convex, the sealing ring is easy to deform due to unstable compression in the sealing cover process, so that the sealing ring is inconvenient to stably press in the groove body, water leakage of the water pump is caused, meanwhile, the existing sealing ring is of a single-layer isolation structure, more vibration is generated when the water pump works, and a protection gap is formed under the influence of the vibration of the sealing ring, so that water leakage is caused.

Disclosure of Invention

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, a membrane 3 water pump that leakproofness is good, including pump body 1 and closing cap 2, closing cap 2's inboard still is provided with membrane 3, closing cap 2 is located the outer fringe of membrane 3 and is provided with first cell body 5, be provided with second cell body 6 on the pump body 1, second cell body 6 is provided with N group, the total width of N group second cell body 6 is less than or equal to the width of first cell body 5, the inside of first cell body 5 and second cell body 6 is provided with sealing washer 4, sealing washer 4's top is provided with the straight portion with first cell body 5 joint, sealing washer 4's bottom is provided with N group arch 7, N group arch 7 corresponds the joint with N group second cell body 6.

The sealing groove of current diaphragm 3 water pump adopts to be single structure with the structure of sealing washer 4, sealing washer 4 is when the encapsulation, the top of sealing washer 4 supports the area of pressing and is little, this just makes sealing washer 4 appear the equipment problem easily, sealing washer 4 extrusion deformation appears the gap thereby leak, in this scheme, widen the upper portion of sealing washer 4, the lower part is the protruding 7 structures of N group, thereby on the one hand increased the upper surface area of sealing washer 4, can make the encapsulation process more stable, the packaging effect is better, on the other hand the protruding 7 structures of N group of sealing washer 4 have realized that N is sealed, compared with the current sealing washer 4 structure, the separation effect is better, thereby have better leakproofness, the protruding 7 collocation N of N group of while is the structure of second cell body 6, can make sealing washer 4 more inseparable laminating on the water pump under the vibration condition, thereby reach better leak protection effect.

Further, N is set to 2.

In the scheme, the second groove body 6 is provided with two groove structures, the lower part of the sealing ring 4 is correspondingly provided with two groups of bulges 7, the wider upper part of the sealing ring 4 enables the sealing ring 4 to be convenient to press and package, and the lower part of the sealing ring 4 forms two barriers to ensure the sealing performance; in other possible embodiments, N may be set to 3 groups and 4 groups, but corresponding to the above, multiple grooves are needed to be formed on the pump body 1, which has better sealing effect, but the overall manufacturing cost is higher, in another embodiment, N may also be set to 1 group, the upper portion and the lower portion of the sealing ring 4 are both widened structures, so that the sealing ring is convenient to package, the middle portion of the sealing ring 4 is concave, and in the extrusion state, the sealing ring 4 has elasticity so that the sealing ring can better weaken the influence of vibration, thereby ensuring the sealing performance of the water pump.

Further, the sealing ring 4 is made of rubber or resin.

In this scheme, sealing washer 4 is selected to have good resilience and rubber or resin material, specifically, for guaranteeing water pump life, selects wear-resisting corrosion-resistant rubber and resin.

Working principle: this scheme starts multiunit cell body on pump body 1, the lower part of corresponding sealing washer 4 sets up multiunit arch 7 to widened sealing washer 4's upper surface area, can make the encapsulation process more stable, the packaging effect is better, simultaneously, sealing performance is better, avoids the water pump to leak, and sealing washer 4's structure also makes sealing washer 4 and cell body's contact more stable, makes sealing washer 4 also can be inseparable laminating on the water pump under the vibration condition, thereby reaches better leak protection water effect.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
