Technical Field

The utility model relates to a kitchen utensil's technical field specifically, relates to a sealed pad and cigarette machine.

Background

With the improvement of the living standard of people, the requirement of a user on a kitchen is continuously improved, and the experience of a cigarette machine becomes a pursuit trend in modern life.

An air outlet seat is connected to an air outlet of a cigarette machine box body of the cigarette machine, and the air outlet seat is connected with an air pipe so as to discharge the absorbed oil smoke to the outdoor or flue through the air outlet, the air outlet seat and the air pipe of the cigarette machine box body in sequence. A rubber sealing gasket is clamped between the edge of the air outlet and the root of the air outlet seat to prevent the oil leakage between the edge of the air outlet and the root of the air outlet seat.

However, the rubber material has a high hardness, and thus cannot be tightly attached to the edge of the air outlet and the root of the air outlet seat. Therefore, the rubber sealing gasket cannot fill up gaps generated in the installation process or the deformation of the structure, and the problem of oil leakage cannot be completely solved.

SUMMERY OF THE UTILITY MODEL

In order to at least partially solve the problems of the prior art, according to one aspect of the present invention, a gasket is provided. The sealing gasket is used for forming sealing between the air outlet and the air outlet seat of the box body of the cigarette machine, and comprises a base layer, a first sealing layer and a second sealing layer, wherein the first sealing layer and the second sealing layer are arranged on two sides of the base layer, and the Shore hardness of the first sealing layer and the Shore hardness of the second sealing layer are smaller than 45 degrees.

Because the traditional sealing gasket is made of rubber, and the Shore hardness of the rubber is 45-50 degrees. Therefore, when the shore hardness of the first sealant layer and the second sealant layer is controlled to be less than 45 degrees, the hardness of both sides of the gasket can be reduced. Therefore, even if a certain gap exists between the edge of the air outlet and the root of the air outlet seat due to installation errors or structural errors of the edge of the air outlet, the root of the air outlet seat or the sealing gasket, the gap can be filled by the sealing layers with smaller hardness at two sides of the sealing gasket.

Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description illustrates only a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In addition, some technical features that are well known in the art are not described in detail in order to avoid obscuring the present invention.

In order to form good sealing between the air outlet and the air outlet seat of the cigarette machine box body of the cigarette machine, the utility model provides a novel sealing gasket. In addition, the cigarette machine adopting the sealing gasket is also included. The range hood includes, but is not limited to, side-draft, top-draft, ohn and the like.

As shown in fig. 1-4, a cigarette maker may include a cigarette maker case (not shown), a blowout seat 100, and a gasket 200.

The base portion 110 of the outlet 100 may be attached to the cigarette case at any suitable location by any suitable means such as welding, connector attachment, snap fit, etc. The box body of the cigarette machine can be provided with an air outlet. The air outlet 100 may be connected to an air outlet. The head 120 of the outlet 100 opposite the base 110 may be connected to an air duct (not shown) through which smoke from the interior of the range hood may be discharged to the exterior or into a flue through the outlet 100. The construction of the cigarette case and the outlet 100 is well known in the art and will not be described in further detail herein.

The gasket 200 may be clamped between the edge of the outlet and the root 110 of the outlet base 100. The edge of the air outlet refers to a portion of the air outlet for connecting with the root 110 of the air outlet seat 100. Thus, the edge of the outlet port faces the gasket 200 after assembly. The root 110 of the outlet base 100 refers to a portion where the outlet base 100 is connected to an edge of the outlet. Therefore, the root 110 of the outlet frame 100 faces the gasket 200 after assembly.

As known to those skilled in the art, the gasket 200 is provided with a vent hole 240 so that the soot in the cabinet of the range hood can pass through the vent hole 240 and be discharged to the outside or a flue through the outlet seat 100. Gasket 200 may include a base layer 230, a first sealant layer 210, and a second sealant layer 220. First sealant layer 210 and second sealant layer 220 can be the same or different. The first sealant 210 and the second sealant 220 may be disposed on both sides of the base layer 230 in any suitable manner such as by fitting. Preferably, the first sealant 210, the base layer 230, and the second sealant 220 may be bonded to each other. Thus, the production and the manufacture are convenient, and the cost is low. The first sealant layer 210 may be applied against the edge of the outlet vent to seal between the edge of the outlet vent and the gasket 200. The second sealant layer 220 may abut the root 110 of the outlet 100 to seal between the root 110 of the outlet 100 and the gasket 200. That is, the edge of the air outlet is clamped by the root 110 of the air outlet seat 100, so that the sealing gasket 200 is deformed, thereby sealing the air outlet seat and the air outlet seat. Alternatively, the gasket 200 may be formed in an integral manner. That is, the first sealant 210 and the second sealant 220 may be disposed on both sides of the base layer 230 by being integrally formed.

Because the traditional sealing gasket is made of rubber, and the Shore hardness of the rubber is 45-50 degrees. Therefore, when the shore hardness of the first sealant 210 and the second sealant 220 is controlled to be less than 45 degrees, the hardness of both sides of the gasket 200 may be reduced. Thus, even if a gap exists between the edge of the air outlet and the root 110 of the air outlet seat 100 due to an installation error, or a structural error of the edge of the air outlet, the root 110 of the air outlet seat 100, or the sealing layer 200 itself, the gap may be filled up by the sealing layer having a small hardness on both sides of the sealing layer 200. Like this, the leakproofness between the edge of air outlet and the root 110 of air-out seat 100 is better, and the probability that the oil leak takes place reduces, and user's use experiences betterly.

Preferably, the shore hardness of first and second sealant layers 210 and 220 may be less than the shore hardness of base layer 230. That is, the shore hardness of the foundation layer 230 may be greater than or equal to 45 degrees. Thus, the higher hardness of the base layer 230 can support the first sealant layer 210 and the second sealant layer 220, thereby facilitating the installation, storage, and transportation of the gasket 200.

Preferably, the shore hardness of the base layer 230 may be 45-50 degrees. With this arrangement, the foundation layer 230 can support the basic shape of the gasket 200. And when the Shore hardness is 45-50 degrees, common rubber can be selected to manufacture the base layer, so that the existing sealing gasket can be used as the base layer 230, the inventory can be cleaned, and the cost is reduced. Preferably, the shore hardness of first seal layer 210 and/or second seal layer 220 may be 30-40 degrees. The shore hardness of the first sealing layer 210 and the second sealing layer 220 within the above range can better fill up the gap between the edge of the air outlet and the root 110 of the air outlet seat 100, thereby further improving the sealing performance. Too soft may increase the manufacturing difficulty and too hard may decrease the sealing effect, and is therefore optimal within the above interval.

Preferably, the base layer 230 may be a rubber layer or a fine silica gel layer. That is, the base layer 230 may be made of rubber or fine-meshed silicone. Rubber or fine-pored silicone rubber is known to those skilled in the art and will not be described in detail for the sake of brevity. Through the arrangement, the rubber layer or the fine-pore silica gel layer is made of materials commonly used in the field, the processing technology is mature, the processing cost is low, and the hardness is proper.

Preferably, the first sealant 210 and/or the second sealant 220 may be a silicone layer. That is, first sealant 210 and/or second sealant 220 may be made of various silicone materials known in the art, so long as the hardness is satisfactory. Further, first sealant 210 and/or second sealant 220 can be made from commercially available silica gels having slow recovery properties. When the silica gel contacts oil, the silica gel expands, so that the sealing performance can be better improved.

Preferably, first sealant 210, second sealant 220, and base layer 230 may be elastic layers. Thus, when the gasket 200 is excessively deformed due to a mounting error, the first sealant 210, the second sealant 220, and the base layer 230 having elasticity may gradually return to their original shapes, so that the gap between the edge of the outlet and the root 110 of the outlet seat 100 may be better filled.

Preferably, the thickness of the gasket 200 may be 3 to 9 mm. The thickness of the first sealant 210 may be 1-3 mm. The thickness of the base layer 230 may be 1-3 mm. The thickness of second encapsulant layer 220 may be 1-3 mm. When the thickness is too small, the above structure may be clamped to be damaged, thereby failing to achieve a good sealing effect. When the thickness is too large, material waste may result, thereby resulting in an increase in the cost of the cigarette machine.

Preferably, as shown in fig. 3, the first sealant 210 may be complementary in structure to the edge of the outlet mouth where the first sealant 210 abuts the edge of the outlet mouth. That is to say, when the edge of air outlet is provided with rib, sunken or protruding isotructure, first sealing layer 210 can be structurally with the edge adaptation of air outlet, for example correspondingly be provided with slot, protruding or sunken isotructure to can laminate the edge of air outlet completely, thereby further improve the leakproofness. Similarly, at the position where the second sealing layer 220 abuts against the root 110 of the wind outlet seat 100, the second sealing layer 220 may be complementary to the root of the wind outlet seat 100 in structure. That is, when the root 110 of the wind outlet seat 100 is provided with a rib, a recess, a protrusion, or the like, the second sealing layer 220 may be structurally matched with the root 110 of the wind outlet seat 100, for example, a slot, a protrusion, a recess, or the like is correspondingly provided, so as to completely fit the root 110 of the wind outlet seat 100, thereby further improving the sealing performance.

Preferably, referring to fig. 2-3 in combination, first sealant layer 210 may be provided with a first annular groove 211. The edge of the outlet may be inserted into the first annular groove 211. A second annular groove 221 may be provided on the second sealant layer 220. The root 110 of the outlet frame 100 may be inserted into the second annular groove 221. In this way, first sealant 210 and second sealant 220 may form a seal at multiple surfaces, further improving sealability.

Preferably, as shown in figures 2 and 4, the machine may also include a connector. Connectors include, but are not limited to, bolts, screws, rivets, and the like. The gasket 200 may be provided with a coupling hole 250. The number and structure of the coupling holes 250 may be adapted to the coupling members. A connector may pass through the air outlet 100, the attachment hole 250 of the gasket 200, and the case of the cigarette machine to attach the air outlet 100 to the case of the cigarette machine. Such a coupling structure is simple and inexpensive to manufacture, and the gasket 200 can be securely fixed between the outlet frame 100 and the body of the cigarette maker by the coupling member.
