DETAILED DESCRIPTION
[0033] The specific implementation of the utility model will be described below with reference to the accompanying drawings of the specification.
[0034] As a specific embodiment, the desktop range hood with a front oil box in the embodiment of the utility model includes a base 1, an exhaust assembly 2 and an oil box 3.
[0035] The exhaust assembly 2 includes an outer cover 21 and a fan assembly 29 disposed in the outer cover 21 ; the outer cover 21 is provided with a front inlet 211 and a rear outlet 212 , and air flows from the front inlet 211 to the rear outlet 212 when the fan assembly 29 is in operation.
[0036] The base 1 is connected to the bottom end of the outer cover 21. For example, the connection is fixed, or the connection is achieved by the following method. Usually, a base circuit board 19 for controlling the fan assembly 29 is arranged on the base 1.
[0037] The exhaust assembly 2 also includes an oil collecting member 22 , which includes a filter screen 229 and an oil collecting frame 221 with an oil leakage port 222 at the bottom. The filter screen 229 is fixed on the oil collecting frame 221 and covers the inner cavity of the oil collecting frame 221 .
[0038] The bottom end of the front inlet 211 is provided with an oil box groove 23, and the oil box 3 is inserted into the oil box groove 23 from the front inlet 211 toward the rear outlet 212, and the oil leakage port 222 faces the inner cavity of the oil box 3. Usually, in order to set the oil box groove 23, the front end of the outer cover 21 will extend outward to form an oil box groove wall 239.
[0039] The working principle is that when the fan assembly 29 is in operation, the air flows from the front inlet 211 to the rear outlet 212, so that the air containing oil smoke passes through the filter 229. After the oil smoke is adsorbed by the filter 229, it forms larger oil droplets and flows downward, flows into the inner cavity of the oil box 3 through the oil leakage port 222 to form the oil to be cleaned. When the oil to be cleaned in the oil box 3 accumulates to a certain extent, the oil box 3 is taken out and the oil to be cleaned inside is cleaned, and then the oil box 3 is reset and reused.
[0040] It can be seen from the above that the oil droplet flow path is short and only passes through the oil collecting piece 22 and the front inlet 211, so there is less oil to be cleaned attached to the desktop range hood, which is beneficial to keeping the desktop range hood clean; in addition, the base 1 placed on the desktop is completely isolated from the oil to be cleaned, which can ensure that the desktop is cleaner.
[0041] As one of the specific implementations, the front inlet 211 is provided with a pin slot 213, and the oil collecting frame 221 is provided with a pin 223 inserted into the pin slot 213, so that the oil collecting member 22 is retained in the front inlet 211. The oil collecting member 22 can be removed from the front inlet 211, which is convenient for cleaning the oil collecting member 22.
[0042] As one of the specific implementations, the pin 223 is located below the oil collecting frame 221, which refers to the bottom of a substantially horizontal plane passing through the axis of the oil collecting frame 221, and the top of the oil collecting frame 221 abuts against the top of the front inlet 211. When removing the oil collecting member 22, the top of the oil collecting member 22 is moved outward to tilt the oil collecting member 22, and then the oil collecting member 22 is moved tilted as a whole so that the pin 223 is pulled out of the pin slot 213, and the oil collecting member 22 can be removed; in this process, the position of the oil leakage port 222 at the bottom of the oil collecting frame 221 remains roughly opposite to the oil box 3. At this time, even if the oil drops from the oil leakage port 222 due to the vibration of the oil collecting member 22 being removed, the oil drops will fall into the oil box 3. After the pin 223 is inserted into the pin slot 213, the top of the oil collecting frame 221 is pushed to complete the installation of the oil collecting member 22. As can be seen from the above, it is easy to disassemble and install the oil collecting member 22 to the front inlet 211, and it can also ensure the cleanliness when disassembling the oil collecting member 22. Usually, the top of the oil collecting frame 221 extends outward along its axis, and the outwardly extending part is provided with a top hole 224, which increases the contact area between the oil collecting frame 221 and the top of the front inlet 211, and facilitates the top of the oil collecting member 22 to be moved outward by inserting a finger into the top hole 224. Of course, a buckle that cooperates with the top hole 224 can also be provided at the top of the front inlet 211 to improve the installation firmness of the oil collecting member 22. It should be noted that the oil collecting frame 221 can be made of plastic and has elasticity, so it can be slightly deformed to achieve the above movement.
[0043] As one of the specific implementations, the bottom end of the oil box groove 23 is completely exposed from the front inlet 211, and a sealing body 31 facing the front inlet 211 is provided on the outside of the oil box 3. When the oil box 3 is fully inserted into the oil box groove 23, the sealing body 31 abuts against the bottom end of the oil collecting frame 221, which can ensure that the oil leakage port 222 at the bottom end of the oil collecting frame 221 faces the inner cavity of the oil box 3. Usually, the outer side surface of the sealing body 31 and the front inlet 211 together form a complete truncated cone or bowl-shaped curved surface.
[0044] As one of the specific implementations, an elastic oil box buckle 231 is provided on the outside of the oil box groove 23, and the oil box buckle 231 abuts against the outer side of the oil box 3, which can ensure the installation stability of the oil box 3. An operating body 39 is provided on the outer side of the oil box 3, extending downward, so that the oil box 3 can be pulled out of the oil box groove 23 with a large force. Of course, a magnetic body [such as a magnet] or a magnetic body [such as an iron block attracted by a magnet, etc., which is not shown in the drawings of this implementation] can also be provided in the oil box groove 23.
[0045] As one of the specific implementations, a hinged ear 24 is provided at the bottom end of the exhaust assembly 2; and a swivel connection end 14 hinged to the hinged ear 24 is directly or indirectly provided on the housing 11. For example, the swivel connection end 14 is directly and integrally provided on the housing 11, so that the swivel connection end 14 is directly provided on the housing 11. The exhaust assembly 2 can rotate relative to the base 1 to adjust the exhaust angle. It is easy to understand that the exhaust assembly 2 relies on friction or a conventional gear structure to maintain the angle of the exhaust assembly 2 after rotation. Usually, the hinged ear 24 or the swivel connection end 14 is provided with a rotation limit table 141 to limit the rotation angle of the exhaust assembly 2.
[0046] As one of the specific implementations, the base 1 further includes a lifting member 12, and the housing 11 is provided with a lifting member slot 112; the lifting member 12 is inserted into the lifting member slot 112 and can move along the lifting member slot 112, and the rotating connection end 14 is fixed to the top of the lifting member 12, so that the rotating connection end 14 is indirectly provided on the housing 11. The exhaust assembly 2 can be raised and lowered relative to the base 1 to adjust the exhaust height.
[0047] As one of the specific implementations, the base 1 also includes a lifting operating member 13 and a return spring 134. The lifting operating member 13 is directly or indirectly hinged to the housing 11. The two ends of the hinge axis of the lifting operating member 13 and the housing 11 are respectively a lifting control end 131 and a lifting operating end 133. The lifting control end 131 is provided with a lifting control body 132 inserted into the lifting hole 123. The return spring 134 is respectively connected to the lifting operating member 13 and the base 1 so that the lifting control end 131 has a tendency to be inserted into the lifting hole 123. For example, the two ends of the return spring 134 are respectively against the lifting operating end 133 and the inner wall of the operating member box 138 described later so that the lifting control end 131 and the lifting control body 132 tend to be close to the lifting hole 123, and then the lifting control end 131 has a tendency to be inserted into the lifting hole 123. After pressing the lifting operation end 133 to pull the lifting control body 132 out of the lifting hole 123, the lifting component 12 and the exhaust component 2 can be moved; then stop pressing the lifting operation end 133, the lifting control end 131 is reset and inserted into the lifting hole 123, so that the height of the lifting component 12 and the exhaust component 2 is maintained, thereby being able to adjust and lock the exhaust height.
[0048] As one of the specific implementations, the base 1 further includes an operating member box 138, the lifting operating member 13 is hinged to the operating member box 138, for example, by a pin passing through an operating member hinge hole 139 of the operating member box 138, and the operating member box 138 is detachably fixed to the housing 11 so that the lifting operating member 13 is indirectly hinged to the housing 11, for example, by being fixed to the housing 11 by a buckle, so as to facilitate the assembly of the base 1.
