Description

A water tank ventilation structure

technical field

The utility model relates to a ventilating structure of a water tank.

Background technique

At present, the ventilation structure of the water tank 2 on domestic engineering machinery or vehicles is: the water tank cover 1 is provided with an air hole 11 (as shown in Figure 1 ) communicated with the inside of the water tank 2, to meet the needs of ventilation, when the water tank 2 discharges water, External air enters into the water tank 2 through the air holes 11 on the water tank cover 1 to ensure smooth flow of water in the water tank 2 . Because construction machinery or vehicles often work under harsh environmental conditions, the water in the water tank 2 will continuously shake up and down, left and right when the whole machine is running, so that the splashed water in the water tank 2 is easy to flow from the water tank cover 1. Air hole 11 overflows.

Utility model content

The purpose of the utility model is to provide a water tank ventilation structure, which solves the problem that the water splashed in the water tank easily overflows from the air hole on the water tank cover under the premise of satisfying the ventilation.

In order to solve the above technical problems, the technical solution of the utility model is: a water tank ventilation structure, including a water tank, a water tank cover is threaded on the water tank, and a first ventilation hole communicating with the inside of the water tank is provided on the water tank cover ; An inner pad is provided between the water tank cover and the water tank, and a cavity communicating with the first vent hole is provided between the inner pad and the water tank cover;

The inner pad is provided with second air holes communicating with the cavity and the inside of the water tank, and the second air holes are arranged in a staggered manner with the first air holes.

As an improvement, the water tank cover is provided with a boss extending into the cavity, and the boss is provided with a third vent hole communicating with the cavity and the first vent hole, The third air hole and the second air hole are arranged in a staggered manner; there is a distance between the end of the boss close to the inner pad and the inner pad.

As a further improvement, a plurality of second vent holes are provided in a circular shape on the inner pad.

As a further improvement, a gasket is provided between the water tank cover and the water tank, a connecting portion extends from a side of the gasket, and the other end of the connecting portion is clamped on the water tank cover.

Due to the adoption of the above technical solution, the beneficial effects of a water tank ventilation structure provided by the utility model are as follows:

Since the inner pad is provided with a second vent hole that is staggered with the first vent hole, and both the first vent hole and the second vent hole communicate with the cavity, the outside air passes through the first vent hole, the cavity and the second vent hole in sequence. The ventilation hole finally enters the inside of the water tank, which ensures the ventilation of the water tank and the smoothness of the water discharge from the water tank; when the water in the water tank shakes, it is blocked by the inner pad and the water is blocked back into the water tank. At the same time, it is staggered The first ventilation hole and the second ventilation hole are provided to effectively prevent the splashed water from directly entering the first ventilation hole and overflowing, thus ensuring the anti-overflow effect of the ventilation structure of the water tank.

Since the water tank cover is provided with a boss extending into the cavity, and there is a distance between the boss and the inner pad, after the water in the water tank sloshes and enters the cavity, it is stopped by the boss for a second time, and after stopping The water flowing down along the boss under the action of gravity further prevents water from entering the first vent hole and overflowing, further improving the anti-overflow effect of the vent structure of the water tank.

Since there are multiple second vent holes in the inner pad, the smoothness of the ventilation is ensured by the plurality of second vent holes, and it is prevented that when there is only one second vent hole, it will affect the ventilation of the water tank and the ability to discharge water if it is blocked. Smooth effect; at the same time, the water entering the cavity can quickly flow into the water tank through a plurality of second ventilation holes, avoiding water accumulation in the cavity, and further ensuring the effect of the water tank ventilation structure preventing water from overflowing.

Since there is a sealing gasket between the water tank cover and the water tank, the sealing between the water tank cover and the water tank is further ensured by the sealing gasket, and the friction between the water tank cover and the water tank cover is increased by the sealing gasket to ensure that the water tank cover is in the water tank. The fixing effect on the surface; since the side of the gasket extends with a connecting part, the other end of the connecting part is clamped on the water tank cover, so that the water tank cover and the water tank are connected together through the connecting part to prevent the water tank cover from being lost.

detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Fig. 2 and Fig. 3 together, a kind of water tank ventilation structure comprises water tank 2, and this water tank 2 is threadedly installed with water tank cover 1, and this water tank cover 1 is provided with the first ventilation hole 12 that communicates with the inside of water tank 2; An inner pad 3 is provided between the water tank cover 1 and the water tank 2, and a cavity 5 communicating with the first vent hole 12 is provided between the inner pad 3 and the water tank cover 1; 5, the boss 13 in the inner pad 3 is provided with a distance between the end of the boss 13 and the inner pad 3; the boss 13 is provided with a third channel that communicates with the cavity 5 and the first air hole 12 Air hole 131 , the diameter of the third air hole 131 is larger than the diameter of the first air hole 12 .

The inner pad 3 is provided with a plurality of second ventilation holes 14 all communicating with the cavity 5 and the inside of the water tank 2, and the second ventilation holes 14 and the third ventilation holes 131 are staggered so that when the water in the water tank 2 sloshes When the inner pad 3 is used to block and block the water back into the water tank 2, supplemented by the third vent hole 131 and the second vent hole 14 arranged in a staggered manner, it effectively prevents the splashed water from directly entering the first vent hole 12. The inner overflow ensures the anti-overflow effect of the ventilation structure of the water tank; at the same time, through a plurality of second ventilation holes 14, the smoothness of ventilation is further ensured, preventing the ventilation of the water tank 2 from being blocked if there is only one second ventilation hole 14 Moreover, the water entering the cavity 5 can quickly flow into the water tank 2 through a plurality of second ventilation holes 14, avoiding the accumulation of water in the cavity 5, and further ensuring the ventilation of the water tank The structure prevents water from overflowing.

A sealing gasket 4 is arranged between the water tank cover 1 and the water tank 2, and a connecting portion 41 extends from the side of the sealing gasket 4, and the other end of the connecting portion 41 is clamped on the water tank cover 1, thereby further ensuring The tightness between the water tank cover 1 and the water tank 2 increases the friction between the water tank cover 1 and the water tank cover 1 through the gasket 4 at the same time, which ensures the fixing effect of the water tank cover 1 on the water tank 2; It is connected with the water tank 2 to prevent the water tank cover 1 from being lost.
