Referring to fig. 1, a conveying device 100 according to an embodiment of the present invention is provided for a household appliance 40, the conveying device 100 includes a feeding component 10 and a conveying component 20 disposed on one side of the feeding component 10, and the feeding component 10 includes a quantitative cavity 11 and a movable switch 12. The quantitative cavity 11 is provided with a quantitative cavity 111 and a feed opening 112 for accommodating materials, the quantitative cavity 111 is communicated with the feed opening 112, the switch 12 is used for closing the feed opening 112 or opening the feed opening 112, the conveying component 20 is provided with a fluid passage 219, and the fluid passage 219 is used for conveying fluid.

The above-mentioned conveying device 100, the feeding component 10 and the conveying component 20 are independently arranged and operated, so that the feeding component 10 and the conveying component 20 can be independently controlled, and the control process of the household appliance 40 with the conveying device 100 is simple and easy to implement.

Specifically, the feeding unit 10 and the conveying unit 20 are independently provided, and referring to fig. 1, 12 to 16, among the feeding unit 10 and the conveying unit 20, only the feeding unit 10, only the conveying unit 20, or both the feeding unit 10 and the conveying unit 20 may be operated.

In this manner, when only the feeding member 10 is operated, the feeding member 10 can feed the material along the feed opening 112. Alternatively, the delivery member 20 may deliver fluid when only the delivery member 20 is operational.

Under the condition that the feeding component 10 and the conveying component 20 work simultaneously, the conveying component 20 can convey fluid while the feeding component 10 feeds the fluid, so that the working efficiency is accelerated on the premise that the feeding component 10 and the conveying component 20 do not influence each other. Other embodiments are not specifically limited herein.

In one example, after the feeding component 10 operates for a certain period of time, the feeding component 10 stops conveying the material, and the conveying component 20 starts conveying the fluid; in another example, the conveying unit 20 is preset with an operating time period, and after the feeding unit 10 starts operating and reaches the preset operating time period, the conveying unit 20 starts operating. In this way, the working sequence of the working time of the feeding component 10 and the conveying component 20 can be specifically set, and the adaptability is improved. Other embodiments are not specifically limited herein.

It should be noted that the conveying component 20 is disposed on one side of the feeding component 10, which means that the feeding component 10 and the conveying component 20 are disposed adjacently. The feeding component 10 and the conveying component 20 can be arranged at intervals or can be arranged in an abutting mode. The feeding component 10 and the conveying component 20 may be spaced apart, which means that there is a certain distance between the feeding component 10 and the conveying component 20. For example, the interval distance (mm) between the feeding part 10 and the conveying part 20 may be in the range of [50, 60 ]. Specifically, the distance between the feeding member 10 and the conveying member 20 may be 50mm, 51mm, 52mm, 53mm, 54mm, 55mm, 56mm, 57mm, 58mm, 59mm, 60 mm.

The feeding component 10 and the conveying component 20 are arranged against each other, which means that the feeding component 10 and the conveying component 20 are partially contacted without forming a gap between the feeding component 10 and the conveying component 20.

In certain embodiments, the feeding component 10 includes a first powered component 14, the first powered component 14 being configured to deliver material to the dosing chamber 111. Therefore, the quantitative measuring of the quantitative cavity 111 to the material can be realized.

The volume of the dosing chamber 111 is a pre-designed constant value. In particular, the predetermined amount of material contained by the dosing chamber 111 may be the volume of the material filling the dosing chamber 111. Alternatively, the maximum value of the capacity of the dosing chamber 111 is designed to be a predetermined value. The maximum volume of the quantitative cavity 111 may be 100ml, 200ml, 300ml, 1000ml, or other specific volumes. Therefore, the material can be metered during the process of conveying the material by conveying the material to the metering cavity 111 until the metering cavity 111 is filled.

Referring to fig. 2 and 3, it can be understood that the quantitative cavity 111 has a bottom and a top, and the space between the bottom and the top of the quantitative cavity 111 is the maximum capacity of the quantitative cavity 111, in one example, the maximum capacity of the quantitative cavity 111 is 1000m L, when the material enters the quantitative cavity 111, the material falls into the space in the quantitative cavity 111 and is stacked upwards to the top position until the material is fully stacked in the quantitative cavity 111, at which time, the first power part 14 is controlled to stop conveying the material, and the volume of the material in the quantitative cavity 111 is 1000m L.

Of course, the preset volume may be a volume of the dosing chamber 111 smaller than the maximum volume.

It should be noted that if the exterior of the feeding member 10 requires a predetermined amount of material larger than the dosing chamber 111, the feeding member 10 may feed the material out of the feeding member 10 several times in a divided manner, for example, the maximum capacity of the feeding member 10 is 100m L, and 300ml of material is required for the exterior of the feeding member 10, the feeding member 10 may feed the material out of the feeding member 10 3 times in a divided manner.

In addition, the feeding unit 10 can accurately feed the material, which is multiplied by the predetermined amount of the dosing chamber 111, to the outside of the feeding unit 10. For example, the predetermined amount of the quantitative cavity 111 is 100ml, the feeding member 10 can accurately feed materials of 100ml, 200ml, 300ml, and the like to the outside of the feeding member 10.

In one example, the feeding member 10 may be provided with a sensor for detecting whether the amount of the material in the quantitative cavity 111 reaches a preset capacity, and in case that the amount of the material reaches the preset capacity, the first power member 14 may be controlled to stop operating. The sensors may include, but are not limited to, light sensors, weight sensors, and the like.

In another example, when the material is fully accumulated in the quantitative cavity 111, the resistance is increased when the first power component 14 conveys the material, the voltage or current change amplitude of the first power component 14 is larger than a threshold value, and at this time, it can be determined that the material is quantitatively weighed in the quantitative cavity 111 by detecting the voltage or current of the first power component 14, and the household appliance 40 controls the first power component 14 to stop conveying the material to the quantitative cavity 111. The time period for the first power component 14 to convey the material can be set in advance, and can also be selected according to specific situations, and is not limited in detail here.

In some embodiments, referring to fig. 2, the household appliance 40 further includes a feeding pipe 15, the feeding pipe 15 connects the storage device 11 and the feeding component 10, and the first power component 14 can feed the material in the storage device 11 to the dosing cavity 111 along the feeding pipe 15. Therefore, the material can be conveniently and quantitatively measured.

It will be appreciated that communication between the magazine 11 and the feed member 10 may also be achieved by other means of connection. In one example, the magazine 11 and the feed member 10 are integrally connected. A partition plate having a through hole structure may be provided between the magazine 11 and the feeding member 10. The material in the storing device 11 can be conveyed to the feeding part 10 through the through hole structure.

In another example, the magazine 11 and the feed member 10 are distributed up and down. The storing device 11 is provided with an opening to the feeding part 10, through which the material in the storing device 11 can be conveyed to the feeding part 10.

In yet another example, the feeding unit 10 and the stocker 11 are distributed up and down. Specifically, the magazine 11 and the feeding member 10 communicate through a feeding pipe 15. Other embodiments are not specifically limited herein.

In some embodiments, the feeding component 10 includes a driving assembly 17, the driving assembly 17 is connected to the switch member 12, and the driving assembly 17 is configured to drive the switch member 12 to move so that the switch member 12 opens the feeding opening 112 and/or closes the feeding opening 112. In this manner, movement of the switch member 12 is achieved to open the feed opening 112 and/or close the feed opening 112.

In addition, the driving assembly 17 includes at least one of the following structures: cylinder, hydro-cylinder, electromagnetism spare, motor. Referring to fig. 3, in the illustrated embodiment, the drive assembly 17 includes a cylinder structure. Specifically, the quantitative cavity 11 is provided with a receiving space 113 spaced apart from the quantitative cavity 111, the driving assembly 17 includes a fixed member 171 and a moving member 172, the fixed member 171 is disposed in the receiving space 113, the moving member 172 is connected to the switching member 12, the moving member 172 is partially received in the fixed member 171 and is movable relative to the fixed member 171, and the switching member 12 is connected to the moving member 172 and moves with the movement of the moving member 172. In this way, the moving member 172, and thus the opening and closing member 12, may be moved by introducing and/or extracting gas into and/or from the fixed member 171.

The driving assembly 17 includes an air pump, referring to fig. 3, the air pump can introduce air into the fixed member 171 from the through hole 173 at the top of the fixed member 171 to drive the moving member 172 to extend out of the fixed member 171, and the moving member 172 drives the switch member 12 to open the discharging opening 112, which realizes that the driving assembly 17 drives the switch member 12 to move so that the switch member 12 opens the discharging opening 112.

In some embodiments, the driving assembly 17 includes a first restoring member 174, the first restoring member 174 is connected to the moving member 172, the fixed member 171 is configured to be filled with fluid so that the moving member 172 drives the opening and closing member 12 to open the feed opening 112, and the first restoring member 174 is configured to provide a force to the moving member 172 to close the opening and closing member 12 to the feed opening 112. In this manner, the first restoring member 174 can provide a force to the moving member 172 to close the feed opening 112 with the switch member 12.

Specifically, the first restoring member 174 includes at least one of the following structures: elastic component, hydraulic pressure spare, air casting die, motor, magnetic part. In the illustrated embodiment, the first restoring member 174 includes an elastic member, such as a spring. The elastic member is located in the fixed member 171, and one end of the elastic member abuts against the bottom portion 216 in the fixed member 171, and the other end abuts against one end of the moving member 172 in the fixed member 171, so that the elastic member provides an upward pushing force to the moving member 172.

Under the condition of no gas pressure, the moving member 172 keeps the opening and closing member 12 in a state of closing the feed opening 112 under the action of the elastic member. When the moving member 172 is driven by the gas pressure to move downward, the elastic member is compressed, and when the gas pressure is removed, the elastic member drives the moving member 172 to reset and move upward, thereby driving the switch member 12 to close the feed opening 112 again.

In other embodiments, an elastic member may be coupled to the top of the moving member 172, the elastic member providing an upward pulling force to the moving member 172. The opening and closing member 12 is maintained in a state of closing the feed opening 112 in the absence of gas pressure.

It will be appreciated that both upward pushing and pulling forces may be provided by two or more elastic members. The driving principle of the hydraulic part, the pneumatic part, the motor and the magnetic part is similar to that of the elastic part, and the driving principle is not expanded in detail.

In the case where the first restoring member 174 includes a magnetic member, the magnetic member may include a permanent magnetic member, and may also include an electromagnetic member. The moving member 172 itself may be magnetic or another magnetic member may be fixed on the moving member 172, and the moving member 172 may be reset by the force (including attraction or repulsion) of the two magnetic members. The first restoring member 174 may also include a combination of two or more of an elastic member, a hydraulic member, a pneumatic member, a motor, and a magnetic member.

In addition, one end of the moving member 172 located in the fixed member 171 may be in sealing connection with the inner side surface of the fixed member 171 to maintain the stability of the air pressure.

In another embodiment, the air pump can introduce air into the fixed member 171 from the through hole 173 at the top of the fixed member 171 to drive the moving member 172 to extend out of the fixed member 171, and the moving member 172 drives the switch member 12 to open the feed opening 112. The air pump can also pump air into the fixed part 171 through the through hole 173 to form a negative pressure in the fixed part 171, so that the moving part 172 drives the switch part 12 to close the feed opening 112, and the air pump keeps pumping air to keep the switch part 12 in a state of closing the feed opening 112. This enables the driving assembly 17 to drive the opening and closing member 12 to move so that the opening and closing member 12 opens the feed opening 112 and closes the feed opening 112.

In another embodiment, the air pump can inject air into the fixed member 171 from the through hole 173 (not shown) of the bottom 216 of the fixed member 171, so that the moving member 172 moves upward to drive the switch member 12 to close the feed opening 112 and maintain the switch member 12 in a state of closing the feed opening 112. When the gas pressure is removed, the moving member 172 can move downward by its own weight, and the opening/closing member 12 is driven to open the feed opening 112. This realizes that the driving assembly 17 drives the switching member 12 to move so that the switching member 12 closes the feed opening 112, and also maintains the state that the switching member 12 closes the feed opening 112.

The moving member 172 can be connected to the switch member 12 by means of a snap, a thread, an interference, or an adhesive, which is not limited herein.

It should be noted that the principle and structure of driving the switch member 12 to move by the oil cylinder structure are similar to those of driving the switch member 12 to move by the air cylinder structure. Where the drive assembly 17 comprises a motor, the motor may be coupled to the mover 172 through a transmission assembly including, but not limited to, a belt, gears, screws, hinges, and the like. In the case where the drive assembly 17 includes an electromagnetic member, the moving member 172 itself may be magnetic or a magnetic member may be fixed to the moving member 172, and the moving member 172 may be moved by the force (including attractive or repulsive force) of the electromagnetic member on the magnetic member. The driving assembly 17 may also include a combination of two or more of a cylinder, a motor, and an electromagnetic member.

In summary, in some embodiments, the fixed part 171 is used for introducing fluid to make the moving part 172 drive the opening and closing part 12 to open the feed opening 112. In some embodiments, the fixed part 171 is used for introducing fluid to make the moving part 172 drive the switch part 12 to open the feed opening 112, and for outputting fluid to make the moving part 172 drive the switch part 12 to close the feed opening 112 and keep the switch part 12 in a state of closing the feed opening 112. Wherein the fluid may comprise a liquid and a gas.

In some embodiments, referring to fig. 5-7, the delivery member 20 includes a retraction assembly 21 and a delivery tube 218 connected to the retraction assembly 21, the delivery tube 218 defining a fluid passage 219. In this manner, delivery member 20 may cooperate with retraction assembly 21 to deliver fluid.

It will be appreciated that the distance between the ends of retraction assembly 21 may vary as retraction assembly 21 is extended or retracted. By providing the duct 218, fluid is ensured to be conveyed along the fluid path 219 without being affected by extension or retraction of the retraction assembly 21.

Specifically, the delivery tube 218 may be coupled to the interior of the delivery member 20, and the maximum length of the delivery tube 218 may be greater than the maximum extendable length of the retraction assembly 21.

Preferably, the duct 218 may be helical. In this way, duct 218 can be stacked and has a minimum stretchable length corresponding to retraction assembly 21, facilitating mounting and dismounting of duct 218, avoiding disengagement and breakage of duct 218 when duct 218 is stretched in the up-down direction, so that fluid passage 219 cannot communicate.

Referring to fig. 5-7, in some embodiments, the delivery member 20 is configured to selectively input a liquid or gas into the fluid passageway 219 or selectively extract a liquid or gas from the fluid passageway 219. As such, the fluid passage 219 may be used to perform the functions of water intake, water pumping, and air intake of the delivery member 20.

Specifically, the delivery member 20 may be fluidly input through a fluid passageway 219. When the fluid is liquid, the liquid can be introduced into the fluid passage 219 at one end of the fluid passage 219 and output at the other end of the fluid passage 219 to realize the delivery of the liquid; when the fluid is gas, the gas can be pressed or pushed into or sucked into the fluid channel 219 at one end of the fluid channel 219 by an external force, and output at the other end of the fluid channel 219, so that the gas can be conveyed.

The delivery member 20 may be used to selectively pass a liquid or gas into the fluid passage 219. In some embodiments, the delivery member 20 is used to pass liquid into the fluid passage 219. For example, when washing rice or cooking rice, water may be introduced into the rice cooker through the fluid passage 219. In some embodiments, the transport member 20 is used to introduce gas into the fluid passage 219, for example, during a rice washing stage, gas may be introduced into the water to perform bubble rice washing.

The transport component 20 may be used to selectively draw liquid or gas from the fluid passage 219. In certain embodiments, the delivery member 20 is used to draw liquid from the fluid passageway 219. For example, after washing rice, along the fluid path 219, the rice washing water may be drawn out of the rice cooker. Or water rich in sugar can be pumped out of the electric cooker during the rice cooking process. In some embodiments, the delivery member 20 is used to draw gas from the fluid passageway 219, such as water vapor that may be drawn from within an electric rice cooker during a rice cooking process.

In some embodiments, referring to fig. 5, the expansion assembly 21 is formed with a first port 211 and a second port 212, a delivery pipe 218 is disposed through the first port 211 and partially disposed in the expansion assembly 21, the delivery pipe 218 communicates with the second port 212, the delivery pipe 218 is used for outputting the fluid entering the fluid passage 219 through the second port 212, and/or the delivery pipe 218 is used for outputting the fluid entering the fluid passage 219 through the second port 212. In this manner, the installation of the delivery tube 218 and the unidirectional and/or bidirectional delivery of the second fluid using the delivery tube 218 may be accomplished.

Specifically, the delivery tube 218 extends from the first port 211 of the retraction assembly 21 into the retraction assembly 21 and communicates within the retraction assembly 21 to the second port 212. In the expansion direction, the first port 211 and the second port 212 are respectively provided at both end portions of the expansion assembly 21.

In the illustrated embodiment, the first port 211 is provided at a top 213 of the telescoping assembly 21 and the second port 212 is provided at a bottom 216 of the telescoping assembly 21. The other end of tube 218, which is located outside of retraction assembly 21, may be connected to a fluid source, such as a gas or liquid source.

In one example, the delivery tube 218 may be a silicone tube. It is understood that in other examples, the delivery tube 218 may be other flexible or resilient tubes.

In the case where the duct 218 is used to output the fluid entering the fluid passage 219 from the second port 212, the fluid can be conveyed along the duct 218 to the second port 212 and be input from the second port 212 to the outside of the telescopic assembly 21 to the inside of the household appliance 40. The fluid may be a gas and/or a liquid. Thus, the functions of liquid inlet and air inlet are realized.

In case the duct 218 is used for outputting the fluid entering the fluid passage 219 from the second port 212, the fluid may be outputted from the inside of the household appliance 40 along the duct 218. The fluid may be a gas and/or a liquid. Thus, the functions of liquid pumping and air pumping are realized.

In summary, the delivery pipe 218 is used for outputting the fluid entering the fluid passage 219 from the second port 212, and/or the delivery pipe 218 is used for outputting the fluid entering the fluid passage 219 from the second port 212, that is, the delivery pipe 218 can realize the bidirectional flow direction delivery of the fluid, or realize one of the unidirectional delivery. May be configured according to the functional requirements of the household appliance 40. And is not particularly limited herein.

Additionally, in the embodiment shown in FIG. 5, a sealing element may be disposed between the delivery tube 218 and the first port 211 to ensure a better seal within the retraction assembly 21 to prevent fluid leakage.

In some embodiments, referring to FIG. 6, the retraction assembly 21 is formed with a first port 211 and a second port 212, a delivery tube 218 is positioned within the retraction assembly 21 and communicates the first port 211 and the second port 212, the delivery tube 218 is configured to allow fluid entering the fluid passageway 219 from the first port 211 to exit the second port 212, and/or the delivery tube 218 is configured to allow fluid entering the fluid passageway 219 from the second port 212 to exit the first port 211. In this manner, installation of the delivery tube 218 and unidirectional and/or bidirectional delivery of the second fluid using the delivery tube 218 may also be achieved.

Specifically, in the case where the delivery pipe 218 is used to cause the fluid, which enters the fluid passage 219 from the first port 211, to be output from the second port 212, the fluid can be delivered to the second port 212 through the first port 211. The fluid may be a gas and/or a liquid. Thus, the functions of liquid inlet and air inlet are realized.

In the case where the delivery pipe 218 is used to cause the fluid, which enters the fluid passage 219 from the second port 212, to be output from the first port 211, the fluid may be delivered to the first port 211 along the delivery pipe 218. The fluid may be a gas and/or a liquid. Thus, the functions of liquid pumping and air pumping are realized.

It should be noted that the following embodiments will be described and explained with reference to the embodiment of the telescopic assembly 21 shown in fig. 6. It is to be understood that the description and explanation given in connection with the embodiment shown in fig. 6 also applies substantially to the telescopic assembly 21 of the embodiment shown in fig. 5.

In addition, referring to fig. 6, in some embodiments, the telescopic assembly 21 has a top portion 213 and a bottom portion 216 along the telescopic direction, the first port 211 is disposed at the top portion 213, and the second port 212 is disposed at the bottom portion 216. In this manner, placement of delivery tube 218 within retraction assembly 21 is facilitated.

Specifically, in the illustrated embodiment, the delivery tube 218 is helical and is positioned within the sealed space 220. Thus, in the case where the duct 218 moves as the expansion unit 21 expands and contracts, the spiral duct 218 facilitates the movement of the duct 218. Specifically, the duct 218 may be extendable and retractable in an up-and-down direction in cooperation with the retraction assembly 21.

Accordingly, via the second port 212, the second fluid may flow along the fluid passageway 219 to the first port 211, performing the function of pumping the second fluid. Meanwhile, the telescopic assembly 21 drives the conveying pipe 218 to extend and retract in the up-and-down direction, so that the conveying part 20 can occupy a small space. In one example, the first port 211 and the second port 212 may be disposed at the top portion 213 and the bottom portion 216, respectively, along a central axis direction of the retraction assembly 21. Thus, the processing is convenient.

Referring to fig. 6 and 7, in some embodiments, the telescopic assembly 21 includes a plurality of telescopic members 22, the telescopic members 22 are all hollow structures, the telescopic members 22 are sequentially sleeved along the telescopic direction, and the innermost telescopic member 22 forms a bottom 216. Thus, the arrangement of the telescopic structure of the telescopic assembly 21 and the sealed space 220 is realized, and the structure is simple.

Specifically, each of the plurality of expansion members 22 has a hollow columnar structure. Along the up-down direction, the top portion 213 is formed on the top one of the telescopic members 22, and the other telescopic members 22 are sequentially sleeved on the telescopic member 22 located on the top portion 213 and extend to the bottom portion 216. In the up-down direction, the extensible member 22 having the smallest cross-sectional area is located innermost, and one end portion thereof is sealed to form a bottom 216. Adjacent telescoping members 22 are slidable relative to each other.

In some embodiments, the telescoping assembly 21 includes a first end member 214 connected to the outermost telescoping member 22 and positioned at the top 213, the first end member 214 defining a first port 211 and the bottom 216 defining a second port 212. In this manner, the process handling of the first end member 214 is facilitated.

Referring to fig. 6 and 7, in particular, the telescopic member 22 has an opening along the telescopic direction. First end member 214 is disposed at the opening of outermost telescoping member 22. In this manner, first end member 214 may seal the opening of outermost telescoping member 22.

It will be appreciated that providing the first port 211 in the first end member 214 provides a better fit of the first end member 214. Specifically, first end member 214 may seal openings of telescoping members 22 of different calibers. In this way, the installation of the first port 211 and the connection between the delivery pipe 218 and the telescopic assembly 21 are not affected in the event of a change in the number of telescopic elements 22.

In addition, in one example, the cross-sections of the plurality of telescopic members 22 in the up-down direction may be all circular rings, so that the telescopic assembly 21 is easy to process. In other embodiments, the cross-section of the plurality of telescoping members 22 perpendicular to the telescoping direction may be rectangular, triangular, and other regular or irregular polygons, etc.

Referring additionally to fig. 6 and 7, in some embodiments, the retraction assembly 21 includes a second end member 217, the second end member 217 is disposed at the bottom 216, and the second end member 217 covers the second port 212. In this manner, objects may be prevented from blocking the second port 212.

Specifically, in the illustrated embodiment, the opening of the second port 212 is facing downward. The second port 212, which is open downward, is easily blocked by objects (e.g., rice) inside the household appliance 40 during the process of extending the telescopic assembly 21 downward into the household appliance 40. Thus, covering the second port 212 by the second end member 217 may serve to prevent objects from blocking the second port 212.

In particular, the base 216 and the second end element 217 may be connected to each other by means of threads, snap-fit, welding, interference. The connection method is not particularly limited.

Additionally, in some embodiments, second end member 217 may have a protrusion 2171, protrusion 2171 connecting the outer side of the innermost telescoping member 22, protrusion 2171 serving to limit the telescoping position of the innermost telescoping member 22. Thus, the telescopic effect of the conveying component 20 is ensured, and meanwhile, the structure is simple.

Specifically, referring to fig. 6, the protrusion 2171 corresponds to another expansion member 22 sleeved on the expansion member 22 located at the innermost side. As shown in fig. 6, the innermost extensible member 22 is an extensible member 22d, the other extensible member 22 covering the extensible member 22d is an extensible member 22c, and the protruding portion 2171 protrudes from the outer side surface of the extensible member 22 d.

The protruding portion 2171 can restrict the retractable position of the extensible member 22d during the retraction of the conveyance member 20. For example, in the case where projection 2171 abuts the bottom of telescoping member 22c during retraction of telescoping assembly 21, the retraction stroke of telescoping member 22d is limited by projection 2171.

In some embodiments, a gap 2172 is formed between second end element 217 and bottom 216 in communication with second port 212. In this manner, the transport of fluid at the bottom 216 may be facilitated.

It can be appreciated that by providing the gap 2172, fluid output from the second port 212 is more easily accessible to the interior of the household appliance 40, and fluid from the interior of the household appliance 40 is more easily accessible to the second port 212. In particular, in the case where the fluid in the fluid passage 219 is output by the second port 212, laterally of the second end element 217, the fluid can be more easily conveyed inside the household appliance 40 at the bottom 216; in the event that fluid is delivered from the second port 212 to the fluid passage 219, fluid inside the household appliance 40 may more easily enter the second port 212 along the gap 2172.

In certain embodiments, second end element 217 is formed with filter holes 2173 that communicate with gap 2172. In this manner, the filter apertures 2173 may prevent a larger volume of the second fluid from entering the gap 2172 and blocking the second port 212 in the event that the fluid is transported at the gap 2172.

In the illustrated embodiment, the filter apertures 2173 are provided between the gap 2172 and the external environment. Fluid needs to enter the gap 2172 along the filter holes 2173. In particular, when the household appliance 40 is a rice cooker, the fluid may be water. In the case that the conveying member 20 is used for pumping water in the rice cooker, the filtering holes 2173 can prevent rice grains in the rice cooker from entering the gap 2172, thereby preventing the rice grains from blocking the second port 212 and affecting the conveying efficiency of the conveying member 20. Preferably, the size of the filter holes 2173 may be smaller than the smallest cross section of the rice grains.

In some embodiments, first end member 214 is formed with a third port 215, the plurality of telescoping members 22 and first end member 214 together define a sealed space 220, a delivery tube 218 is disposed within sealed space 220, a fluid passageway 219 is spaced from sealed space 220, and third port 215 communicates with sealed space 220. In this way, the telescoping assembly 21 can be extended and retracted.

It will be appreciated that fluid may be communicated to sealed space 220 to drive retraction assembly 21 to extend. Specifically, the fluid may pass into the sealed space 220 along the third port 215 and create a fluid pressure within the sealed space 220. Fluid pressure may urge retraction assembly 21 to extend downward. In this manner, extension of retraction assembly 21 is achieved.

In the illustrated embodiment, the first port 211 and the third port 215 are not in communication with each other in the first end element 214, avoiding interaction between the fluid for delivery and the fluid for driving the telescopic assembly 21.

In addition, since the first end member 214 can be separately machined with the first port 211 and the third port 215, the first end member 214 can be detachably mounted to the outermost one of the telescoping members 22. In one example, a sealing member may be disposed between first end member 214 and outermost telescoping member 22 to ensure the sealing of sealed space 220.

Additionally, in other embodiments, the transport component 20 may be provided with a transmission (not shown) for driving the extension of the retraction assembly 21. Specifically, the transmission means may include a roller and a pull cord, one end of which is connected to the innermost extensible member 22 and the other end of which is wound around the roller. Retraction assembly 21 can be extended by gravity, at which time the pull cord is released from the roller. When the roller rotates, the roller can roll up the pull rope, so that the telescopic assembly 21 is contracted.

Of course, in other embodiments, retraction assembly 21 may be driven to extend or retract by way of a hydraulic ram.

In some embodiments, plurality of telescoping members 22 includes a first telescoping member 221 and a second telescoping member 224, second telescoping member 224 is slidably disposed within first telescoping member 221, and a seal 23 is disposed between first telescoping member 221 and second telescoping member 224, seal 23 sealing the gap between first telescoping member 221 and second telescoping member 224. Thus, the telescoping assembly 21 can be prevented from being unable to extend or retract due to fluid leakage in the sealed space 220 while achieving the telescoping effect of the telescoping assembly 21.

Referring to fig. 6 and 7, specifically, the cross-sectional area of the first expansion piece 221 in the vertical direction is larger than the cross-sectional area of the second expansion piece 224, and the second expansion piece 224 and the first expansion piece 221 can slide relatively in the vertical direction. This allows second telescoping member 224 to be received within the hollow structure of first telescoping member 221. The sealing member 23 is provided to ensure that the sealing performance of the sealing space 220 can be maintained even when the first telescopic member 221 and the second telescopic member 224 are stationary and relatively moved.

In some embodiments, referring to fig. 8-11, the sealing member 23 includes a mounting portion 231 and a resilient sealing arm 234 protruding from one side of the mounting portion 231. The mounting portion 231 is mounted on the outer side wall of the second expansion piece 224, the elastic sealing arm 234 elastically abuts against the inner side wall of the first expansion piece 221, and a moving space for the elastic sealing arm 234 to elastically deform is formed on one side of the mounting portion 231 where the elastic sealing arm 234 protrudes. In this way, the sealing effect is achieved while the sealing member 23 is prevented from being displaced on the outer side wall of the second telescopic member 224.

Specifically, when the elastic sealing arm 234 elastically abuts against the inner sidewall of the first expansion piece 221, the elastic sealing arm 234 is elastically deformed and pressed into the active space. Since the movable space is enough to accommodate the elastic sealing arm 234, the elastic sealing arm 234 cannot be attached to the surface of the mounting portion 231 located in the movable space, and the elastic sealing arm 234 only exerts an elastic force generated by its elastic deformation on the inner sidewall of the first expansion member 221. In this way, the sealing member 23 does not generate an excessive frictional force on the inner sidewall of the first expansion member 221 while achieving a sealing effect. In this way, the sealing member 23 is not displaced on the inner sidewall of the first telescopic member 221, which may affect the sealing performance of the sealing space 220.

In some embodiments, the second telescopic member 224 is formed with a groove 229, and the mounting portion 231 is mounted in the groove 229. In this manner, groove 229 may serve to confine seal 23 to second telescoping member 224, preventing seal 23 from becoming dislodged.

Referring to fig. 8, the outer sidewall of the second telescopic member 224 may have two side plates along the vertical direction. A groove 229 may be formed between the two side plates. The mounting portion 231 is secured within the recess 229. It will be appreciated that in the event of mutual sliding between first telescopic member 221 and second telescopic member 224, seal 23 is subjected to sliding friction due to the fact that seal 23 is in contact with the surface of first telescopic member 221. By providing a groove 229 on the outer side wall of the second telescopic member 224, the sealing member 23 is prevented from being displaced, which may affect the sealing performance of the sealing space 220.

Referring to fig. 9, in some embodiments, the resilient seal arm 234 includes a first arm 235 and a second arm 236. The first arm 235 extends obliquely upward with respect to the telescopic direction from the mounting portion 231. The second arm 236 is connected to an end of the first arm 235 remote from the mounting portion 231. In this manner, the second telescopic member 224 can be easily slid along the inner sidewall of the first telescopic member 221 while preventing the sealing member 23 from being displaced.

Specifically, the mounting portion 231 extends in the up-down direction, and is formed with a top end 232 and a bottom end 233. Referring to fig. 10, the top end 232 and the bottom end 233 respectively abut against two sides of the inner wall of the groove 229 with interference, and the first arm 235 extends upward from the bottom end 233 of the mounting portion 231 along the direction B and is connected to the second arm 236. The second arm 236 extends upward from the first arm 235 in the C direction. The extension of the first arm 235 in the direction B forms an angle with the mounting portion 231. In this way, a movable space for accommodating the elastic sealing arm 234 is formed between the elastic sealing arm 234 and the mounting portion 231 at an interval, so that a force generated between the sealing member 23 and the inner sidewall of the first expansion member 221 is substantially an elastic force, thereby preventing the sealing member 23 from being displaced. In one example, the C direction is parallel to the telescoping direction.

Specifically, the included angle is an acute angle. Referring to fig. 9 and 10, when the first expansion member 221 is sleeved on the second expansion member 224, the elastic sealing arm 234 can have a guiding function, so as to facilitate the sliding of the second expansion member 224 along the inner sidewall of the first expansion member 221.

In some embodiments, referring to fig. 8, the first telescopic member 221 includes a first cylinder 222 and a first stopping edge 223 extending from the first cylinder 222 into the first cylinder 222. The second telescopic member 224 includes a second cylinder 225 and a second stopper 226 extending from the second cylinder 225 to the outside of the second cylinder 225. Second stop rib 226 cooperates with first stop rib 223 to limit the distance of extension of first telescoping member 221 and second telescoping member 224. Thus, the first and

second expansion members

221 and 224 are prevented from being disengaged.

Specifically, the first stopper 223 extends radially on the inner sidewall of the bottom of the first cylinder 222 and is formed with a through hole 173 through which the second cylinder 225 passes. Second stopper 226 includes first stopper 227 and second stopper 228, and first stopper 227 and second stopper 228 extend radially on the outer side walls of the top and bottom of second cylinder 225, respectively. Correspondingly, the thickness of the first stopping edge 223 may be greater than that of the first stopping edge 227, when the second cylinder 225 passes through the first cylinder 222, the first stopping edge 223 may define the sliding direction of the second cylinder 225 on the inner side wall of the first cylinder 222, and the first stopping edge 227 and the first stopping edge 223 may cooperate to limit the downward extending distance of the second cylinder 225.

Likewise, second flange 228 cooperates with first stop flange 223 to limit the upward telescoping distance of second barrel 225. As such, first and

second stops

223, 226 cooperatively define second telescoping member 224 for sliding movement within first barrel 222. In one example, the positions of the first rib 227 and the second rib 228 on the second cylinder 225 can be freely adjusted. The specific values of the positions of the first rib 227 and the second rib 228 are not limited herein.

Additionally, the second stop edge 226 may define a groove 229. The groove 229 is formed in a ring shape on the second cylinder 225, and two corresponding ring-shaped side plates are formed in the vertical direction. The first rib 227 forms one side plate of the groove 229, and the other side plate of the groove 229 is located above the second rib 226 in the up-down direction. The top end 232 and the bottom end 233 are respectively interference abutted to the two side plates of the groove 229. In this way, the second stopping edge 226 is provided, so that the groove 229 does not need to be provided with a side plate, and the structure is simplified.

In addition, first rib 227 and/or second rib 228 may be removably coupled to second barrel 225. In one example, the first rib 227 is removably coupled to the second barrel 225. Preferably, the second rib 228 is removably coupled to the second cylinder 225. In this manner, the second telescopic member 224 is conveniently slid into the top of the first cylinder 222 along the inner side wall of the first cylinder 222.

In some embodiments, the conveying member 20 includes a second reset element 237 coupled to the retraction assembly 21, the second reset element 237 being configured to drive the retraction assembly 21 to retract. In this manner, a retraction effect of the retraction assembly 21 can be achieved.

Specifically, referring to fig. 8, the first rib 227, the first cylinder 222, the second cylinder 225 and the first rib 223 together define a receiving space 238 therebetween. The second reset piece 237 is disposed in the accommodating space 238. One end of the second resetting member 237 abuts against the bottom of the first retaining edge 227, and the other end of the second resetting member 237 abuts against the top of the first retaining edge 223.

In particular, the fluid is a gas. When the gas is introduced into the sealed space 220 through the third opening 215, the second expansion member 224 is pushed by the gas pressure and slides downward along the inner sidewall of the first expansion member 221. Meanwhile, the second restoring member 237 is pressed in the receiving space 238 and elastically deformed, so that the second restoring member 237 has a tendency to slide and retract the second expansion member 224 into the first expansion member 221.

In the case where the gas is output from the sealed space 220 along the third port 215, the second restoring member 237 is restored and pushes the first rib 227 in the retracting direction. Second telescoping member 224 is ultimately slidably retracted within first telescoping member 221. In this way, the retraction effect of the retraction assembly 21 is achieved. The action principle of the fluid is similar to that of the fluid is gas, and will not be described herein.

In one example, the upper surface of the first stop edge 223 is provided with a ledge for defining the second reset element 237, the ledge also having the effect of thickening the first stop edge 223. Thus, the first stopper edge 223 has a certain strength. In the case that the elastic force exerted by the second returning element 237 on the first stopping edge 223 is too large, the first stopping edge 223 can be prevented from being separated from the first barrel 222 or the first stopping edge 223 from being broken.

In addition, in one example, the second restoring member 237 may elastically connect the top 213 and the first telescoping member 221, and/or the second restoring member 237 may elastically connect the top 213 and the second telescoping member 224. In another example, the second reset element 237 is disposed external to the overall structure of the retraction assembly 21.

In addition, the second returning member 237 may also include a hydraulic member, a pneumatic member (e.g., a cylinder), a motor, and a magnetic member, and the driving principle is similar to that of the elastic member, and thus, will not be described in detail herein. In the case where the second restoring member 237 includes a magnetic member, the magnetic member may include a permanent magnetic member, and may also include an electromagnetic member. The second telescopic member 224 is slid in the telescopic direction within the first telescopic member 221 by the force (including the attractive force or the repulsive force) of the two magnetic members.

In one example, the first stop edge 223 is provided with a permanent magnet and the second stop edge 226 is provided with an electromagnet. In this way, by changing the magnetism of the electromagnetic member, the first stopping edge 223 and the second stopping edge 226 attract or repel each other, and the sliding of the second telescopic member 224 is realized.

In another example, the first and

second stops

223, 226 are each provided with an electromagnet. The second returning member 237 may also include a combination of two or more of an elastic member, a hydraulic member, a pneumatic member, a motor, and a magnetic member, and the other embodiments are not limited thereto.

It is understood that in this embodiment, the first expansion element 221 and the second expansion element 224 do not refer to two specific expansion elements 22 sleeved with each other in the expansion assembly 21, but only for clearly describing the specific related structure between two adjacent expansion elements 22 for achieving the expansion function, any two expansion elements 22 sleeved and connected have the same or similar specific structure between the first expansion element 221 and the second expansion element 224.

In particular, in the illustrated embodiment, the number of telescopic elements 22 is four, i.e.

telescopic elements

22a, 22b, 22c, 22d, in the first case the first telescopic element 221 can be 22a and the second telescopic element 224 can be 22 b; in the second case, first telescoping piece 221 may be 22b, second telescoping piece 224 may be 22 c; in the third case, the first telescopic member 221 may be 22c and the second telescopic member 224 may be 22 d.

It is understood that in other embodiments, the number of the telescopic members 22 can be any number, and the number is not limited herein, and the number of the telescopic members 22 can be set according to specific situations.

Additionally, in some embodiments, the delivery member 20 is further provided with a second power member 47, the second power member 47 being configured to deliver fluid to the first port 211.

Specifically, referring to fig. 12-13, a transfer tube structure for transferring fluid is connected between the second power member 47 and the first port 211. When the fluid is gas, the second power component 47 may comprise a power device such as an air pump; when the fluid is a liquid, the second power component 47 may comprise a power device such as a water pump.

Further, in the case where the second power part 47 can deliver liquid and gas, the second power part 47 may be a combination of an air pump and a water pump, and the air pump and the water pump in the second power part 47 may be operated separately. Of course, the second power component 47 is not limited to only an air pump and a water pump, and in certain embodiments, the second power component 47 may comprise a hydraulic machine. The second power unit 47 is not particularly limited herein.

In one example, the delivery device 100 is further provided with a pressurizing device for engaging the second power member 47. In this manner, in the case where the second power unit 47 supplies the fluid to the first port 211, a greater air pressure or water pressure may be provided, so that the cleaning effect of the transfer device 100 may be enhanced.
