A range hood 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

Referring to fig. 1 to 10, a range hood 100 according to an embodiment of the present invention may include: a cigarette maker main body 10, a driving device (not shown in the drawings), and a cleaning cartridge 20.

The cleaning cartridge 20 may be used to contain a cleaning medium, such as a cleaning solution. The driving means is connected to the main body 10 of the range hood and may be used to drive the flow of cleaning medium. The cleaning cartridge 20 is embedded in the front side of the main body 10 of the cigarette machine, and in particular, the front side of the main body 10 of the cigarette machine may be provided with a groove, and the cleaning cartridge 20 may be disposed in the groove. Further, the cleaning cartridge 20 is connected to the main body 10 of the cigarette maker in a clamping manner. Thus, not only can the cleaning cartridge 20 be firmly installed, but also the cleaning cartridge 20 can be easily disassembled. Meanwhile, the cleaning box 20 is internally arranged, so that the kitchen space of a user is not occupied, and the cleaning box 20 is not affected by the installation position of the range hood 100.

The cleaning box 20 has a cleaning outlet 201, and when the cleaning box 20 is separated from the main body 10 of the cigarette machine, that is, the cleaning box 20 is not clamped with the main body 10 of the cigarette machine, and is taken out from the main body 10 of the cigarette machine, the cleaning outlet 201 can be automatically closed, as shown in fig. 4 and 10, so that the cleaning medium stored in the cleaning box 20 can be effectively prevented from leaking when the cleaning box is taken out. Further, referring to fig. 3 and 9, when the cleaning cartridge 20 is coupled to the main body 10 of the cigarette machine, that is, when the cleaning cartridge 20 is mounted in the main body 10 of the cigarette machine in a built-in manner and is engaged with the main body 10 of the cigarette machine, the cleaning outlet 201 may automatically communicate with the driving device, so that the cleaning medium in the cleaning cartridge 20 may flow under the driving of the driving device. Therefore, no special communication operation is needed, the operation is simpler and more convenient, and the cleaning box 20 is convenient to take and place.

According to the range hood 100 of the embodiment of the invention, the cleaning box 20 is embedded in the front side of the main body 10 of the range hood, and the cleaning box 20 is automatically communicated with the driving device when being installed in place, and the cleaning outlet 201 is automatically closed when the cleaning box 20 is taken out, so that the embedded structure can play a role of hiding the cleaning box 20, is beneficial to saving kitchen space, simplifies the installation of the cleaning box 20, and is convenient for taking and placing the cleaning box 20, the leakage of cleaning medium can be improved when the cleaning box 20 is taken and placed, and the user experience is improved.

According to some embodiments of the present invention, a control valve 30 may be provided at the cleaning outlet 201, and the control valve 30 may be opened when the cleaning cartridge 20 is connected to the main body 10 of the cigarette machine, i.e., when the cleaning cartridge 20 is mounted in place, so that the cleaning cartridge 20 may be automatically communicated with the driving means. When the cleaning cartridge 20 is separated from the main body 10 of the cooker, the control valve 30 may be closed so that the cleaning outlet 201 may be closed, avoiding outflow of the cleaning medium remaining in the cleaning cartridge 20. The control valve 30 can be switched between open and close according to the relative position of the cleaning box 20 and the main body 10 of the cigarette machine, and the control performance is good.

It will be appreciated that the type and specific configuration of the control valve 30 may vary, and that the invention is not particularly limited in this regard. Referring to fig. 1 to 4, in some embodiments of the present invention, a connection pipe 40 communicating with a driving device may be provided on a main body 10 of a cigarette, a control valve 30 may include a valve body 31 provided at a cleaning outlet 201 and movable between an open position and a closed position, when a cleaning cartridge 20 is connected to the main body 10 of the cigarette, the valve body 31 may be stopped against an inlet end of the connection pipe 40, and the valve body 31 may be moved to the open position by pushing of the inlet end of the connection pipe 40 so that the cleaning cartridge 20 may communicate with the driving device, as shown in fig. 3; when the cleaning cartridge 20 is separated from the main body 10 of the cigarette machine, the valve core 31 is gradually separated from the connecting pipe 40 and is not stopped by the connecting pipe 40 any more, and the valve core 31 can be automatically reset to the closing position, so that the cleaning outlet 201 can be closed, as shown in fig. 4. Thus, the valve core 31 can be switched between the open position and the closed position by controlling the position of the cleaning box 20, so that the operation is simpler and more convenient, and the control performance is better.

Referring to fig. 3 and 4, alternatively, both the valve core 31 and the inlet end of the connection pipe 40 extend in the horizontal direction, the valve core 31 is penetrated in the cleaning outlet 201, and the front end of the valve core 31 may be used to close the cleaning outlet 201 from the front side, and the rear end of the valve core 31 may be engaged with the inlet end of the connection pipe 40. Specifically, as shown in fig. 3, when the cleaning cartridge 20 is mounted in place, the rear end of the valve body 31 is stopped against the inlet end of the connection pipe 40, and the valve body 31 is integrally moved forward by the pushing of the inlet end of the connection pipe 40, so that the front end of the valve body 31 can be moved forward, so that the cleaning outlet 201 can be opened. As shown in fig. 4, when the cleaning cartridge 20 is moved forward, the rear end of the valve cartridge 31 is separated from the inlet end of the connection pipe 40, the valve cartridge 31 may be restored to the original position, and the front end of the valve cartridge 31 may be moved backward to close the cleaning outlet 201. In the above structure, the moving direction of the cleaning box 20 and the moving direction of the valve core 31 tend to be consistent, so that the valve core 31 is more convenient to move under the force, the use is more reliable, and the control performance of the control valve 30 is good.

As shown in fig. 3, when the cleaning outlet 201 is opened, the rear end of the valve cartridge 31 may extend into the inlet end of the connection pipe 40. Further, the valve core 31 may be provided with a fluid channel 301, and the fluid channel 301 may be connected to the cleaning outlet 201 and the connecting pipe 40, so that the cleaning medium may enter the connecting pipe 40 from the fluid channel 301 through the cleaning outlet 201 under the driving of the driving device, and the fluidity is good. Alternatively, the fluid passage 301 may include a plurality and be distributed at intervals along the circumferential direction of the spool 31 to enhance the flow effect.

According to some embodiments of the present invention, the rear end of the cleaning cartridge 20 may be provided with a mounting channel 202, and as shown in fig. 3 and 4, the mounting channel 202 may extend in the front-rear direction, and the cleaning outlet 201 may be provided at the front end of the mounting channel 202, i.e., on the front wall surface of the mounting channel 202. The connection pipe 40 may be inserted at the rear end of the installation passage 202, and an outer circumferential surface of the connection pipe 40 is adapted to abut against an inner circumferential surface of the installation passage 202. Specifically, as shown in fig. 3, when the cleaning cartridge 20 is mounted in place, the connection pipe 40 may be inserted into the mounting channel 202, and the outer circumferential surface of the connection pipe 40 may be stopped against the inner circumferential surface of the mounting channel 202. This makes it possible to make the connection between the connection tube 40 and the cleaning cartridge 20 more reliable and to make the sealing more excellent. As shown in fig. 4, when the cleaning cartridge 20 is removed from the inside of the main body 10 of the range hood, the connection pipe 40 may be removed from the installation channel 202, and the outer circumferential surface of the connection pipe 40 may be separated from the inner circumferential surface of the installation channel 202.

Further, as shown in fig. 3 and 4, an annular groove 401 may be provided on the outer circumferential surface of the connection pipe 40, and a seal ring 402 may be provided in the annular groove 401, and the connection pipe 40 may be stopped against the inner circumferential surface of the installation passage 202 by the seal ring 402. Specifically, when the control valve 30 is in the open position, the sealing ring 402 may abut against the inner peripheral surface of the mounting passage 202 to seal the connection pipe 40 with the cleaning cartridge 20; the sealing ring 402 may be separated from the inner circumferential surface of the mounting channel 202 when the control valve 30 is in the closed position.

Alternatively, the shaft cross-sectional shape of the seal ring 402 is not particularly limited, and may be a conventional circular shape, or may be a square shape or an irregular shape. In the embodiment shown in fig. 3 and 4, the seal ring 402 is formed in an axial cross-section as a rectangle with an outer projection that can be used to stop against the inner peripheral surface of the mounting channel 202. Thus, not only can a good sealing effect be ensured, but also friction between the cleaning cartridge 20 and the connection pipe 40 can be reduced when moving, and the operation is more labor-saving.

In some embodiments of the present invention, as shown in fig. 3 and 4, the control valve 30 may further include an elastic member 32, and the valve core 31 may be moved to the closed position under the stop of the elastic member 32 to achieve the reset of the valve core 31. Further, the elastic member 32 may be a coil spring, which may be sleeved on the valve core 31 and stopped between the valve core 31 and the cleaning cartridge 20. Therefore, the structure can be more compact, the force application direction of the elastic member 32 and the moving direction of the valve core 31 tend to be consistent, the mobility of the valve core 31 is better, and the skew is not easy to occur.

It will be appreciated that the automatic resetting of the valve core 31 is not limited to the use of the elastic member 32, but may be other structures capable of achieving the automatic resetting of the valve core 31, for example, the valve core 31 itself may have elasticity, so that the valve core 31 has the property of being capable of being restored, which will be understood and easily achieved by those skilled in the art, and will not be described in detail herein.

With continued reference to fig. 3-4, the valve core 31 may be provided with a seal 33, and the seal 33 may be used to seal the clean outlet 201. Sealing by the seal 33 can improve the sealing effect as compared with sealing directly by the spool 31. Alternatively, the structure of the sealing member 33 may be various, alternatively, as shown in fig. 3 and 4, the sealing member 33 may be a sealing ring, and the sealing member 33 may be sleeved at one end of the valve core 31, and the sealing ring may be stopped on the peripheral edge of the cleaning outlet 201 to close the cleaning outlet 201, so that the sealing effect is good. Alternatively, as shown in fig. 3 and 4, the axial cross section of the seal member 33 may be formed generally in an i-shape, whereby not only the shape stability of the seal member 33 but also the sealing effect may be improved.

In order to enhance the aesthetic appearance of the range hood 100, as shown in fig. 1, the front surface of the cleaning case 20 may be flush with the front surface of the hood body 10. Thus, the overall flatness of the front surface of the range hood 100 can be improved, and the appearance is more neat and beautiful. Alternatively, the front surface of the main body 10 of the range hood and the front surface of the range hood 100 may be formed as inclined surfaces extending obliquely forward and upward with respect to the vertical direction, respectively.

Alternatively, according to some embodiments of the present invention, the front surface of the cleaning cartridge 20 may be provided transparently. Thus, it is more convenient for the user to observe the storage amount of the cleaning medium in the cleaning cartridge 20, and it is advantageous to remind the user to clean the cleaning cartridge 20 in time when not in use.

According to an embodiment of the present invention, the driving device has a delay operation mode for delaying the operation for a predetermined time after the range hood 100 completes one cleaning. That is, when the cleaning box 20 has more cleaning media than required for one cleaning, the driving device can be in a time-delay working mode, and after the range hood 100 finishes one cleaning, the cleaning media still remain in the cleaning box 20, at this time, the driving device is still in a working state, so that the residual cleaning media can be continuously extracted, the user is not required to pour out the excessive cleaning media in the cleaning box 20, and the cleaning media are prevented from accumulating in the cleaning box 20 to deteriorate and mold, and the user experience is affected.

In some embodiments of the present invention, which are not shown, a detecting means for detecting whether the cleaning medium remains may be further provided in the cleaning cartridge 20, and the detecting means may transmit a signal to the driving means when detecting that the cleaning medium remains, so that the driving means may be operated to drain the cleaning medium in the cleaning cartridge 20.
