Abstract

A filter screen is characterized in that a through exhaust duct is fixed on the filter screen and extends upwards and protrudes above an upper edge of the filter screen. The invention further discloses a cup provided with the filter screen. The filter screen and the cup provided with the filter screen have the benefits as follows: by means of the arranged exhaust duct or exhaust pipe, air in the cup can be exhausted, water can be taken smoothly and conveniently, the phenomenon of spilling of water drops is prevented, and hands can be prevented from being scalded. If the exhaust pipe is arranged in the middle of the filter screen, a handle originally arranged on the filter screen can be omitted; only the filter screen is required to be changed, and a cup body of the conventional cup is not required to be changed, and the cost is low; and the filter screen and the cup can be sold independently or sold in set, thereby facilitating popularization.

Description

Filter screen and have the water tumbler of this filter screen

Technical field

The present invention relates to a kind of filter screen and water tumbler, filter screen and the water tumbler of the cup of particularly smooth and easyly pouring water.

Background technology

Existing water tumbler, be typically provided with the filter screen of tealeaves obstruct in cup, shortcoming is: when pouring in cup, owing to the surface tension of water on the filter screen forms moisture film, air under the seal cup Inner filter net, it is not smooth to cause pouring water, and have to rock water tumbler in the emitter edge limit, the boiling water that spills drips also can scald staff, pours water smooth and has potential safety hazard.

Summary of the invention

The objective of the invention is: the smooth and easy filter screen of pouring water of a kind of energy and water tumbler are provided.

The technical solution adopted in the present invention is: a kind of filter screen is characterized in that: fixedly have the exhaust passage that communicates up and down, described exhaust passage to extend upward on the described filter screen and protrude on the upper edge of described filter screen.

The invention also discloses the water tumbler that has above-mentioned filter screen.

The invention has the beneficial effects as follows: because the setting of exhaust passage (blast pipe) can be discharged the air in the water tumbler, the smooth and easy convenience that becomes of fetching water no longer includes water droplet and spills phenomenon, avoids boiling water to scald staff.Blast pipe can save the handle on the former filter screen if be located at the filter screen middle part; Only change filter screen, need not to change the cup of existing water tumbler, cost is low; Filter screen and water tumbler can independent or complete sales, are beneficial to popularization.

Fig. 2 is the use view of the embodiment of the invention 2;

Fig. 3 is the schematic appearance of the embodiment of the invention 3;

Fig. 4 is the decomposing schematic representation of the embodiment of the invention 4;

Among the figure: 1 blast pipe, 2 filter screen sidewalls, 3 filter screens, 4 reinforcements, 5 cups, 6 bowl covers, 7 handles, 8 concave wall, 9 exhaust passages, 10 interior contracting walls.

The specific embodiment

Embodiment 1, as shown in Figure 1:

Fixedly there are filter screen 3, the middle part of filter screen 3 that blast pipe 1 as the exhaust passage is fixedly arranged in the filter screen sidewall 2.Filter screen 3 is used for pouring water in cup, and blast pipe 1 is used for discharging air in the cup.Look the needs of filter screen 3 solid degree, also can set up reinforcement 4 at filter screen 3.But the handle 7 among blast pipe 1 double as Fig. 2 of this moment uses, so can save handle 7.

Embodiment 2, as shown in Figure 2:

Existing water tumbler comprises cup 5, filter screen 3, filter screen sidewall 2, handle 7, reaches bowl cover 6.The present invention is that the tube wall of this blast pipe 1 can also be fixed together with the inwall of filter screen sidewall 2 at the fixing blast pipe 1 as discharge duct in the edge of filter screen 3.

Embodiment 3, as shown in Figure 3:

The periphery of filter screen 3 is filter screen sidewall 2, and filter screen sidewall 2 is provided with concave wall 8, and concave wall 8 is inwardly shunk and extended upward formation from the cup inwall, cooperates with the inwall with cup to constitute exhaust passage 9, and this concave wall 8 is groove shape.

Embodiment 4, as shown in Figure 4:

Be the polygonal cup 5 of fillet for the cross section, filter screen 3 is the fillet multiform limit for matching also, and the concave wall 8 among the embodiment 3 can be groove shape, can expand as the interior contracting wall 10 among the embodiment 4:

One of them fillet of filter screen sidewall 2 from the inwall of cup 5 inwardly shrink and extend upward form in contracting wall 10, cooperate the described exhaust passage 9(of formation such as Fig. 4 dotted line institute region with the inwall with cup 5).Should protrude above filter screen sidewall 2 by interior contracting wall 10.

Filter screen in the various embodiments described above can be made through operations such as punching press, welding by stainless steel material, or by plastic injection-moulded be whole.
