Description

Technical Field

[0001] The invention relates to a tire repair and replenishing air pump, in particular to a honeycomb check valve cover and a tire repair and replenishing air pump having the honeycomb check valve cover. Background Art

[0002] The existing tire repair and refilling pump with tire sealant works by injecting compressed air into a glue bottle and then injecting the tire sealant in the glue bottle into the tire to achieve tire repair. However, the compressed gas will generate high temperature due to the increase in internal energy caused by the work done internally. When the high-temperature gas is sprayed into the glue bottle, the glue in the glue bottle will solidify when it encounters the high-temperature gas and its impact force. The solidified glue is easy to block the valve core of the tire. When the valve core is blocked, it is difficult to inject air into the tire to achieve the tire repair effect. How to prevent the glue from being affected by the high-temperature gas and its impact force and affecting the tire repair effect is a problem that needs to be solved by the existing tire repair and refilling pump.

[0003] It should be noted that the information disclosed in the above background technology section is only used for understanding the background of the present application, and therefore may include information that does not constitute prior art known to ordinary technicians in the field. Summary of the invention

[0004] The main purpose of the present invention is to overcome the defects existing in the above-mentioned background technology and to provide a honeycomb check valve cover and a tire repair and refilling pump having the honeycomb check valve cover.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A honeycomb check valve cover, used for being installed in front of a check valve of a tire repair and air replenishing pump, comprises:

[0007] A honeycomb porous portion having a honeycomb porous air outlet, wherein the air compressed by the air pump is ejected through the check valve and then passes through the honeycomb porous portion, and the air is dispersed by the honeycomb porous air outlet;

[0008] The arc-shaped baffle plate has a side facing the honeycomb porous portion that is an arched arc-shaped surface. The air passes through the porous air outlet holes and then reaches the arc-shaped baffle plate. Under the force of the arc-shaped surface of the arc-shaped baffle plate, the air is deflected to the outside of the arc-shaped baffle plate and continues to flow forward.

[0009] A connecting portion connects the honeycomb porous portion and the arc-shaped baffle.

[0010] Furthermore, the honeycomb-type porous air outlet holes are circular holes or polygonal holes.

[0011] Furthermore, the connecting portion is integrally formed with the honeycomb porous portion and the arc-shaped baffle.

[0012] Furthermore, the connecting portion is assembledly connected to the honeycomb porous portion and the arc-shaped baffle.

[0013] Furthermore, the connecting portion includes two side walls that are symmetrically arranged.

[0014] A tire repair and air replenishing pump, comprising:

[0015] A cylinder tube, used to accommodate a piston rod and compressed air, wherein a front end of the cylinder tube is provided with an air outlet;

[0016] a piston rod disposed in the cylinder tube and used to compress the air by reciprocating motion;

[0017] A check valve is arranged on the air outlet of the cylinder pipe and is used to control the one-way flow of the air ejected from the cylinder pipe to prevent backflow;

[0018] A tire repair liquid bottle is connected to the inflation interface of the air pump and is used to store the tire repair liquid and inject the tire repair liquid into the tire by using the air pressure ejected from the cylinder tube;

[0019] A honeycomb check valve cover, mounted in front of the check valve, comprises:

[0020] A honeycomb porous portion having a honeycomb porous air outlet, wherein the air compressed by the air pump is ejected through the check valve and then passes through the honeycomb porous portion, and the air is dispersed by the honeycomb porous air outlet;

[0021] The arc-shaped baffle has a side facing the honeycomb porous part that is an arched arc surface. Air passes through the porous air outlet holes and then reaches the arc-shaped baffle. Under the force of the arc-shaped surface of the arc-shaped baffle, the air is deflected to the outside of the arc-shaped baffle and continues to flow forward.

[0022] Furthermore, the honeycomb-type porous air outlet holes are circular holes or polygonal holes.

[0023] Furthermore, it also includes a connecting portion, which connects the honeycomb porous portion and the arc-shaped baffle.

[0024] Furthermore, the connecting portion is integrally formed or assembled with the honeycomb porous portion and the arc-shaped baffle.

[0025] Furthermore, the connecting portion includes two side walls that are symmetrically arranged.

[0026] The present invention has the following beneficial effects:

[0027] The present invention provides a honeycomb check valve cover and a tire repair and replenishing air pump having the honeycomb check valve cover. The design of the honeycomb check valve cover effectively reduces the temperature and impact force of the compressed air ejected from the air outlet of the tire repair and replenishing air pump. Specifically, the compressed air first passes through the honeycomb multi-porous air outlet for the first deceleration to disperse the air and reduce the flow rate and temperature; then, the air passes through the arc baffle for the second deceleration to further reduce the flow rate and temperature. This dual deceleration mechanism significantly reduces the risk of the tire repair fluid solidifying due to the influence of the high temperature and impact force of the air, thereby effectively improving the tire repair effect and the reliability of tire repair.
