Technical Field

[0001] The utility model relates to an oil fume purification device, in particular to an oil fume extractor. Background Art

[0002] Range hoods have become one of the indispensable kitchen appliances in modern families. Usually, range hoods include top-suction type and side-suction type. Top-suction range hoods are more and more widely used due to their advantages such as being neat, light and small in space. Top-suction range hoods usually include a fume hood and a fan housing located on the fume hood. A volute, an impeller and a motor driving the impeller are installed in the fan housing.

[0003] In order to improve the fume extraction effect, a top-suction range hood usually has a smoke guide plate below the air inlet. For example, a range hood disclosed in Chinese patent application number 202020912881.5 includes a smoke hood, a smoke guide plate and an oil cup. The smoke guide plate is arranged at the smoke collection cavity formed on the inner wall of the smoke hood, and an air inlet connected to the smoke collection cavity is opened on the top of the smoke hood; another example is a range hood with a suspended smoke guide plate fixed structure disclosed in Chinese patent application number 202223571756.0, including a smoke inhalation cavity, a smoke guide plate and an oil cup. The bottom of the smoke inhalation cavity is provided with a smoke inhalation port, which is covered by a filter net, the smoke guide plate is arranged below the filter net in a suspended manner, and the oil cup is arranged below one side of the smoke guide plate.

[0004] In the above-mentioned existing top-suction range hood with a smoke guide plate, an oil cup is installed below the smoke guide plate. During the disassembly and assembly of the oil cup, since there is a large space below the top-suction range hood, the user has to rely on his hands to control the balance during the disassembly and assembly process, which can easily cause the oil cup to tip over and cause oil spillage. In addition, electronic devices are currently used to monitor the liquid level of the oil cup, and the equipment is expensive and the cost is high. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide a range hood to reduce the risk of oil cup tipping over in view of the deficiencies in the above-mentioned prior art.

[0006] The second technical problem to be solved by the present invention is to provide a range hood that is convenient for monitoring the oil cup liquid level, has a simple structure and reduces costs in view of the deficiencies in the above-mentioned prior art.

[0007] The utility model solves the above-mentioned first technical problem by adopting a technical solution: a range hood, comprising a smoke collecting hood, an oil cup and a smoke guide plate, wherein an air inlet is formed on the smoke collecting hood, the smoke guide plate is arranged below the air inlet, the smoke guide plate comprises a plate body, and the oil cup comprises a cup body; the characteristics are:

[0008] The smoke guide plate also includes flanges formed at least on the left and right sides of the plate body, and the flanges are formed by bending the edges of the plate body upward. The oil cup also includes pulleys arranged on the left and right sides of the cup body, and the pulleys are slidably or rollingly matched with the flanges, so that the oil cup can move back and forth along the smoke guide plate when being disassembled and assembled.

[0009] By making the oil cup include a pulley and using the smoke guide plate as a guide rail, the oil cup moves from front to back along the smoke guide plate when installing, and moves from back to front along the smoke guide plate when removing the oil cup, and is removed when it moves to the front end of the smoke guide plate. Therefore, during the process of removing the oil cup, the smoke guide plate always keeps the oil cup balanced, reducing the risk of oil spilling without affecting the user experience. In addition, the existing smoke guide plate of the range hood is used, so there is no need to set up a separate guide rail, and the structure is simple.

[0010] Furthermore, in order to facilitate the setting of the pulley and avoid interference between the cup body and the smoke guide plate, the oil cup also includes hooks arranged on the left and right sides of the cup body, the two hooks extend toward each other from the top of the cup body, and the pulley is arranged on the hooks.

[0011] In order to facilitate the oil cup to be moved into position along the smoke guide plate and fixed to the smoke hood, the range hood also includes a mounting structure for mounting the oil cup, the mounting structure includes a fixing structure and a fixed bumper fixed on the oil cup, the fixing structure has two groups, each group of fixing structures includes a fixing bracket fixed to the smoke hood and a bumper arranged in the fixing bracket, the fixed bumper also has two and is respectively arranged on the left and right sides of the oil cup, each fixed bumper can be engaged with the corresponding bumper.

[0012] In order to make the bumper stably support the bumper claw, the bumper includes a first buckle portion and a second buckle portion spaced apart from each other, and the fixing structure also includes two first elastic members, each first elastic member corresponds to a buckle portion, so that the two buckles tend to approach each other.

[0013] Preferably, a first baffle is disposed in the fixing bracket, and the first baffle is disposed above the first buckle portion, wherein a first elastic member abuts between the first buckle portion and the first baffle.

[0014] Preferably, a second baffle is disposed in the fixing bracket, and the second baffle is disposed below the second buckle portion, wherein one of the first elastic members abuts between the second buckle portion and the second baffle.

[0015] The technical solution adopted by the utility model to solve the first technical problem mentioned above is: the range hood also includes a second elastic member arranged in the fixed bracket, the second elastic member is supported on the bottom surface of the fixed bracket, the upper end of one of the first elastic members abuts against the bottom surface of the second buckle and the lower end abuts against the top surface of the second elastic member.

[0016] Therefore, since the collision claw is fixed to the oil cup, the increase in the weight of the oil cup will cause the collision claw to sink with it, and then the second elastic member arranged below it will be compressed by the first elastic member. The amount of oil can be determined according to the compression amount of the second elastic member, and then whether to dump the oil cup can be selected. The structure is simple and the cost is low.

[0017] Preferably, the first elastic member and the second elastic member are both springs.

[0018] In order to facilitate the fixing of the mounting structure to the smoke collecting hood, the top end of the fixing bracket is inserted into the smoke collecting hood and fixed by screws.

[0019] Compared with the prior art, the advantages of the utility model are: by making the oil cup include a pulley and utilizing the smoke guide plate as a guide rail, when the oil cup is installed, it moves along the smoke guide plate from front to back, and when the oil cup is removed, it moves along the smoke guide plate from back to front, and is removed when it moves to the front end of the smoke guide plate. Therefore, during the process of removing the oil cup, the smoke guide plate always keeps the oil cup balanced, reducing the risk of oil dumping without affecting the user experience. Since the contact claw is fixed to the oil cup, the increase in the weight of the oil cup will cause the contact claw to sink with it, and then the first elastic member will compress the second elastic member arranged thereunder, and the amount of oil can be determined based on the compression amount of the second elastic member, and then whether to dump the oil cup can be selected. The structure is simple and the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

Since the embodiments disclosed in the present utility model can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0031] See also Figure 1 to Figure 4 A range hood is a top-suction range hood, comprising a smoke hood 1, a fan frame 2 arranged above the smoke hood 1, and an oil cup 3 arranged at the rear bottom of the smoke hood 1, wherein the fan frame 2 is used to arrange a fan system (not shown). The range hood also includes a smoke guide plate 4, which is located in the smoke hood 1 or at least partially below the smoke hood 1 (the air inlet 11 provided on the smoke hood 1 is located above the smoke guide plate 4). The smoke guide plate 4 can be connected to the smoke hood 1 by conventional buckles, hooks and other structures. The arrangement of the smoke guide plate 4 adopts the existing technology and will not be repeated here.

[0032] The smoke guide plate 4 includes a plate body 41 and flanges 42 formed at least on the left and right sides of the plate body 41. The flanges 42 are formed by bending the edge of the plate body 41 upward. In the installed state, the flanges 42 extend forward and backward. In this embodiment, flanges 42 are provided on all sides of the plate body 41, and the flanges 42 on the front and rear sides extend in the left and right directions. The oil cup 3 includes a cup body 31 and hooks 32 provided on the left and right sides of the cup body 31. The hooks 32 are provided with pulleys 33. The two hooks 32 extend toward each other from the top of the cup body 31. Each pulley 33 is slidably matched or rolled with the corresponding flange 42. That is to say, the flange 42 is used as a guide rail for the pulley 33 to guide the movement of the pulley 33. When the oil cup 3 is installed, it moves from front to back along the smoke guide plate 4. When the oil cup 3 is removed, it moves from back to front along the smoke guide plate 4 and is removed when it moves to the front end of the smoke guide plate 4. Therefore, during the process of removing the oil cup 3, the smoke guide plate 4 always keeps the oil cup 3 balanced, reducing the risk of oil dumping without affecting the user experience.

[0033] The range hood also includes a mounting structure for mounting the oil cup 3, see Figures 5 to 9 , which includes a fixed structure and a fixed claw 51 fixed on the oil cup 3. The fixed structure has two groups, one of which is arranged on the left side of the smoke guide plate 4, and the other is arranged on the right side of the smoke guide plate 4. Similarly, there are two fixed claws 51, which are arranged on the left and right sides of the oil cup 3, respectively. Each fixed claw 51 is fixed to the cup body 31 of the oil cup 3. Each group of fixed structures includes a fixed bracket 521, a buckle 522 and a first elastic member 523, wherein the top end of the fixed bracket 521 penetrates into the smoke collecting hood 1 and is fixed by a screw 524. The buckle 522 is arranged in the fixed bracket 521, and the buckle 522 includes a first buckle portion 5221 and a second buckle portion 5222 arranged at intervals in the upper and lower directions, thereby forming a fixed support structure matched with the fixed claw 51. A first baffle 5251 and a second baffle 5252 are also provided in the fixed bracket 521, wherein the first baffle 5251 is fixedly provided above the first buckle 5221, and the second baffle 5252 is fixedly provided below the second buckle 5222, and there are two first elastic members 523, one of which is abutted between the first buckle 5221 and the first baffle 5251.

[0034] The range hood further comprises a second elastic member 6 disposed in the fixed bracket 521, which is disposed below the second baffle 5252 and can be supported on the bottom surface of the fixed bracket 521. The bottom surface here refers to the bottom surface of the fixed bracket 521 itself, or can be a bottom surface formed by another plate. Thus, the upper end of the other first elastic member 523 abuts against the bottom surface of the second buckle 5222, while the lower end passes through the second baffle 5252 and abuts against the top surface of the second elastic member 6.

[0035] The first elastic member 523 and the second elastic member 6 are preferably both springs, and the hardness of the second elastic member 6 is greater than that of the first elastic member 523 .

[0036] When the oil cup 3 is not installed, the first elastic member 523 is in a natural state, and a certain gap is formed between the two buckles of the bumper 522. When the oil cup 3 moves to the rear end along the smoke guide plate 4, the fixed bumper 51 is inserted into the bumper 522 (inserted into the gap formed between the two buckles), thereby opening the two buckles, and the first elastic member 523 is compressed, so that the fixed bumper 51 can be clamped in the bumper 522 under the action of the restoring force of the first elastic member 523. When the oil cup 3 is installed, the pulley 33 is not subjected to force, but the fixed bumper 51 and the fixed structure bear the weight of the oil cup 3 and the oil in the oil cup 3, supporting the oil cup 3 in a fixed position.

[0037] When the oil in the oil cup 3 increases, the fixed contact claw 51 will move downward accordingly with the oil cup 3, thereby pressing the second buckle 5222 downward, thereby compressing the second elastic member 6 through the first elastic member 523 below. According to F=kx (elastic member force formula, where F is the force, k is the elastic coefficient, and x is the deformation), the amount of oil can be determined by the compression of the second elastic member 6, and then whether to dump the oil cup can be selected. Preferably, a mark can be made on the fixed bracket 521. When the second elastic member 6 is compressed to below the mark, it means that the oil in the oil cup 3 exceeds the set limit and the oil cup 3 needs to be dumped. Alternatively, when there is no need to monitor the amount of oil, the first elastic member 523 can also be directly abutted between the second buckle 5222 and the second baffle 5252.
