Abstract
The utility model relates to a filter of a steam coffee maker and comprises a cup body (1), a filter screen (2) and a silicon gel gasket (3), wherein, the bottom of the cup body (1) is provided with a water outlet hole (11); the filter screen (2) is positioned at the inner bottom of the cup body (1); the filter also comprises a bearing block (4) fixing the silicon gel gasket (3) at the outer bottom of the cup body (1); the silicon gel gasket (3) and the bearing block (4) form a gap (5); the gap (5) is communicated with the water outlet hole (11) at the bottom of the cup body (1) and a water outlet hole (41) of the bearing block (4). The utility model forms the gap (5) on the water outlet hole (11) at the bottom of the cup body (1) through the silicon gel gasket (3) and the bearing block (4); before hot water enters the filter, the gap (5) exhausts the air; after hot water enters the filter, the silicon gel gasket (3) is deformed to enlarge the gap (5) when the inside of the filter reaches set pressure, so as to lead coffee liquid to flow out from the filter; after the coffee liquid is exhausted, the pressure inside the filter is unloaded through the gap (5). The filter of the steam coffee maker has the advantages of simple structure, low cost, the capability of guaranteeing the safety of users, etc.
Description
Technical field
The utility model relates to a kind of steam coffee machine, particularly a kind of filter of steam coffee machine.
Background technology
The filter of existing steam coffee machine all is by a helical spring one valve body to be suppressed delivery port place in filter bottom, when the pressure in the filter suppresses elastic force on valve body greater than helical spring, valve body is just opened delivery port, coffee liquid just sprays from delivery port, because valve body is suppressed by spring, so the air in the filter can only spray when coffee liquid sprays simultaneously, when the pressure in the filter suppresses elastic force on valve body less than spring, valve body seals delivery port again, make filter have certain pressure, at this moment if filter is unloaded and will threaten to user's safety.
The utility model content
In order to overcome the above-mentioned defective of prior art, the utility model provides a kind of filter of safe steam coffee machine.
The technical scheme that the utility model adopted is: the filter of steam coffee machine, comprise cup 1, filter screen 2 and silicone gasket 3 compositions, the bottom of cup 1 has an apopore 11, filter screen 2 is positioned at the inner bottom part of cup 1, this filter comprises that also a silicone gasket 3 is fixed on the rest pad 4 of cup 1 outer bottom, silicone gasket 3 forms a slit 5 with rest pad 4, and slit 5 is connected with the apopore 11 of cup 1 bottom and the apopore 41 of rest pad 4.
Described filter screen 2, silicone gasket 3 and rest pad 4 are fixed on the cup 1 by screw 6.
Described rest pad 4 has a projection 42, and silicone gasket 3 is provided with the through hole 31 that can hold projection 42.
Described slit 5 is to be placed in the through hole 31 by projection 42 to form.
The width in described slit 5 is 0.1 to 0.2 millimeter.
The utility model forms a slit 5 by silicone gasket 3 and rest pad 4 at apopore 11 places of cup 1 bottom, and before hot water entered filter, slit 5 emitted air; After hot water entered filter, when reaching the pressure of setting in the filter, silicone gasket 3 distortion made gap 5 become big, thereby coffee liquid can be flowed out from filter, and coffee liquid has been arranged the back and shed the filter internal pressure by gap 5.The filter of such steam coffee machine has simple in structure, and cost is low; And can guarantee advantages such as user's safety.
Description of drawings
Fig. 1 is the exploded view of the filter of steam coffee machine;
Fig. 2 is the cutaway view of the filter of steam coffee machine.
The specific embodiment
As shown in Figure 1 and Figure 2, the filter of steam coffee machine of the present utility model comprises cup 1, filter screen 2 and silicone gasket 3 compositions, and the bottom of cup 1 has an apopore 11, and filter screen 2 is positioned at the inner bottom part of cup 1; Rest pad 4 has a projection 42, silicone gasket 3 is provided with the through hole 31 that can hold projection 42, after rest pad 4 is fixed on cup 1 outer bottom to silicone gasket 3, projection 42 just places and forms a slit 5 in the through hole 31, the width in slit 5 is 0.1 to 0.2 millimeter, thereby can guarantee that the air in the filter and the water of sub-fraction pass through, when the pressure in the filter reaches the pressure of setting, silicone gasket 3 distortion make gap 5 become big, thereby coffee liquid can be flowed out from filter, and coffee liquid has been arranged the back and has been shed the filter internal pressure by gap 5.Slit 5 is connected with the apopore 11 of cup 1 bottom and the apopore 41 of rest pad 4; Filter screen, silicone gasket 3 and rest pad 4 are fixed on the cup 1 by screw 6.
Claims (5)
