The rubber suction nozzle that forms a sealed suction channel for gas items;

A manual air pump as described above, wherein the rubber suction nozzle includes a body, an air inlet is provided at one end of the body, and an air intake channel is provided at the other end of the body, the upper part of the air intake channel is closed, and the An air outlet is provided on the upper side of the air intake passage, and the air outlet communicates with the inner cavity of the transparent cover, and the rubber suction nozzle is fixed on the inside the transparent cover.

A manual air pump as described above, wherein an end cover is provided at the intake end of the cylinder, and a plurality of small holes communicating with the cylinder are provided in the end cover, and the transparent cover set on the end cap.

A manual air pump as described above, wherein a plurality of positioning holes are provided on the bottom of the rubber suction nozzle, and a plurality of positioning holes that can be plugged into the positioning holes are provided on the top of the transparent cover. Protruding post, the positioning post is inserted into the positioning hole.

A manual air pump as described above, wherein a sealing gasket is provided between the end cover and the transparent cover.

A manual air pump as described above, wherein a slope is provided at the air outlet.

The beneficial effects of the utility model are:

The utility model is provided with a rubber suction nozzle on the air suction port of the air pump, which has a good sealing effect when extracting the internal gas of food bags, food boxes and the like, and improves the air suction efficiency. In addition, in the utility model, an air intake channel that can block oil and water is set in the rubber suction nozzle, and an air outlet that communicates with the transparent cover is opened on the side wall of the air intake channel, and oil or water can generally be blocked in the air intake. In the channel, it cannot enter the pump body, even if a small part passes through the intake channel, the transparent cover forms a separate cavity, which can collect the pumped liquid in the transparent cover, effectively preventing the oil from being pumped during the pumping process. Parts and water are pumped into the pump body, and when cleaning is required, the transparent cover can be removed and rinsed with water, which is convenient to use and effectively protects the normal operation of the pump body.

[Detailed ways]

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

A kind of manual suction pump as shown in Figure 1 to 5, comprises cylinder 1, is provided with suction piston 2 in cylinder 1, is provided with a detachable transparent cover 3 at the air inlet end of cylinder 1 seal, The transparent cover 3 is provided with a rubber suction nozzle 4 which can make the transparent cover 3 and the object to be sucked form a sealed air suction channel. When pumping air to food bags, food boxes, etc., the rubber suction nozzle 4 on the air pump of the present invention can effectively form a sealed air suction channel with the air suction holes of food bags and food boxes, and its air extraction effect is good.

The rubber suction nozzle 4 described in the utility model includes a body 41, an air inlet 42 is provided on one end of the body 41, and an air intake channel 43 is provided on the other end of the body 41. The upper part of the air intake channel 43 is closed, and the An air outlet 44 is provided on the upper side of the air inlet passage 43, and the air outlet 44 communicates with the inner cavity of the transparent cover 3, and the rubber suction nozzle 4 passes through the outer wall of the air inlet passage 43. The block 431 is fixed in the transparent cover 3 . The air outlet 44 of the utility model adopts the structure of side opening, and is also provided with a slope to block the outlet, which can effectively block the sucked liquid and prevent the liquid from being drawn into the pump body to affect the pumping performance.
