When the vacuum pump 30 works, the air in the material storage cavity 101 can be extracted through the air inlet pipe 60 and discharged out of the shell 10 through the air outlet hole 104.

The air inlet pipe 60 may extend in the height direction of the housing 10 in the storage chamber 101, and the inlet of the air inlet pipe 60 is closer to the lid 12 than to the bottom of the storage chamber 101. Because the foodstuff begins to pile up from the bottom of storage cavity 101, consequently the entry through setting up intake pipe 60 is closer to lid 12, can avoid the foodstuff to block up into intake pipe 60 as far as possible for vacuum pump 30 can smoothly carry out evacuation work.

Optionally, a one-way air inlet valve 61 may be disposed in the air inlet pipe 60, wherein the one-way air inlet valve 61 allows air to flow out from the storage chamber 101 through the air inlet pipe 60, but does not allow air to flow into the storage chamber 101 from the air inlet pipe 60.

The power of the stirring member 20 and the vacuum pump 30 can be derived from the driving mechanism 40. The drive mechanism 40 is provided to the housing 10. Further, the driving mechanism 40 may be provided in the base 11. In the present embodiment, the driving mechanism 40 is drivingly connected to the stirring member 20 and the vacuum pump 30, and the driving mechanism 40 is used for driving the stirring member 20 to stir the foodstuff in the storage cavity 101 and for driving the vacuum pump 30 to pump the gas in the storage cavity 101.

The drive mechanism 40 may be electrically connected to the electronic control board 70. The electronic control board 70 may control the operation of the drive mechanism 40. Automatically controlled board 70 can be for example when control actuating mechanism 40 operation simultaneous control ultraviolet emission piece 80, and then make stirring piece 20 when stirring the foodstuff in storage cavity 101, vacuum pump 30 can carry out the evacuation to storage cavity 101, and ultraviolet emission piece 80 still launches ultraviolet ray simultaneously, can stir "ventilative" the foodstuff in, take out the moisture and carry out germicidal treatment, can guarantee the drying and the cleanness of foodstuff as far as possible, can promote long when the storage of foodstuff.

Alternatively, as shown in fig. 4, the drive mechanism 40 has a first output shaft and a second output shaft. A first output shaft of the driving mechanism 40 is in transmission connection with the stirring part 20, and a second output shaft of the driving mechanism 40 is in transmission connection with the vacuum pump 30. In operation of the drive mechanism 40, the first output shaft and the second output shaft rotate simultaneously. The first output shaft drives the stirring member 20 to stir by rotating. The stirring member 20 includes, for example, a sleeve portion and at least one stirring blade, the stirring blade is disposed at the periphery of the sleeve portion, and the sleeve portion can be sleeved on the first output shaft and is fixedly connected to the first output shaft. The second output shaft drives the vacuum pump 30 to perform vacuum pumping work through rotation. For example, the second output shaft is in transmission connection with an impeller in the vacuum pump 30, and drives the impeller to rotate, so as to pump out the gas in the material storage chamber 101. The driving mechanism 40 can more conveniently drive the stirring member 20 and the vacuum pump 30 simultaneously by providing the first output shaft and the second output shaft. The first output shaft and the second output shaft are independent of each other so that the stirring member 20 and the vacuum pump 30 can be driven to operate simultaneously by the first output shaft and the second output shaft which are independent of each other by the same set of driving mechanism 40.

As shown in fig. 4, the driving mechanism 40 may include a driving motor 41 and a reduction gear box 42. The driving motor 41 and the reduction gearbox 42 can be located outside the material storage chamber 101. The driving motor 41 can be electrically connected to the electronic control board 70, so that the electronic control board 70 can control the operation of the driving motor 41. The drive motor 41 may have output shafts extending outwardly from opposite sides thereof. In other words, the driving motor 41 may be a two-shaft motor.

One end of the output shaft of the driving motor 41 is connected with the reduction box 42. Specifically, one end of the output shaft of the drive motor 41 may be connected to the input side or the input shaft of the reduction gear box 42. The output shaft of the reduction gearbox 42 can be used as a first output shaft and is in transmission connection with the stirring element 20. The other end of the output shaft of the driving motor 41 is used as a second output shaft and is in transmission connection with the vacuum pump 30.

Because vacuum pump 30 often needs higher rotational speed at the during operation, and stirring 20 leads to blocking easily or leading to the foodstuff to be flown fast and destroy casing 10 under higher rotational speed, there is the potential safety hazard, consequently can driving motor 41 can connect stirring 20 through reducing gear box 42 transmission, reduce the rotational speed of stirring 20, and then can carry out abundant stirring to the foodstuff, and simultaneously can also make vacuum pump 30 can extract the gas in storage cavity 101 more fast and effectively, promote the effect of stirring and evacuation, and utilize same driving motor 41 to realize stirring and evacuation simultaneously, can save the cost effectively, can promote space utilization.

The following describes exemplary structures and processes of blanking, heating and conveying foodstuff.

As shown in fig. 2, when feeding is required, foodstuff may fall into the heating chamber 102 while stirring. When feeding is not required, foodstuff may then be stored in the hopper chamber 101 without falling into the heating chamber 102. The present embodiment can switch on or off the path between the stocker chamber 101 and the heating chamber 102 by providing the first switch assembly 130.

The housing 10 is opened with a channel 105 communicating the material storage chamber 101 and the heating chamber 102. Specifically, the bottom of the storage chamber 101 may be provided with a first channel segment, and the heating chamber 102 may be provided with a second channel segment, wherein the first channel segment and the second channel segment are in butt communication to form a channel 105.

The first switch assembly 130 can be disposed in the channel 105 for opening or closing the channel 105, such that the material storage chamber 101 and the heating chamber 102 are connected or not connected. By providing the first switch assembly 130 to open or close the passageway 105, both feeding and non-feeding needs can be addressed quickly. The stirring member 20 may be arranged adjacent to the channel 105, e.g. the stirring blades of the stirring member 20 may be located above the channel 105, thereby enabling the stirring member 20 to push foodstuff into the channel 105 during stirring.

As shown in fig. 2, after the first switch assembly 130 opens the path between the hopper chamber 101 and the heating chamber 102, foodstuff may flow from the hopper chamber 101 to the heating chamber 102 where it may be heated. The foodstuff may not be output to the outside before being heated in the heating chamber 102, but may be output to the outside after the heating is completed. The second switch assembly 140 may be configured to open or close the path between the heating cavity 102 and the outside.

A second switch assembly 140 may be disposed in the heating cavity 102 for opening or closing the discharge hole 103. Specifically, the second switch assembly 140 may be disposed in the heat pipe 13 to open or close the passage between the heating cavity 102 and the outside. Here, opening or closing the discharge hole 103 means opening or closing a passage between the discharge hole 103 and the heating chamber 102.

The first and

second switching assemblies

130 and 140, etc., are exemplarily described below.

As shown in fig. 5, the first switching assembly 130 may include a first electromagnet 131 and a first block piece 132. The first electromagnet 131 is a push-pull type electromagnet, and may be a direct-acting push-pull type electromagnet. The first blocking piece 132 is connected to the first electromagnet 131, for example the first blocking piece 132 may be fixedly connected to a push-pull rod of the first electromagnet 131. A first closure 132 is movably disposed in the passageway 105. For example, the first closure 132 may be movably disposed between the first channel section and the second channel section. The first electromagnet 131 may be used to push or pull the first closure 132 such that the first closure 132 opens or closes the channel 105. Specifically, the first electromagnet 131 operates to perform a telescopic motion on the push-pull rod, so as to push and pull the first blocking member 132, so that the first blocking member 132 can open or block the channel 105. Here, the first blocking member 132 may be partially opened or fully opened to open the passage 105, and only the blanking function is required. The first blocking member 132 is, for example, plate-shaped and sized to block the blanking communication 105.

The first electromagnet 131 can be electrically connected to the electronic control board 70, and the operation of the first electromagnet 131 is controlled by the electronic control board 70. For example, the electric control board 70 controls the first electromagnet 131 to pull the first blocking piece 132 backward after the feeding function is started, so that the channel 105 is opened. Meanwhile, the electric control board 70 can also control the driving motor 41 to operate, so that the stirring part 20 synchronously stirs and the vacuum pump 30 synchronously pumps vacuum. The stirring member 20 may push foodstuff into the channel 105 during the stirring process.

As shown in fig. 5, foodstuff may be heated within heating chamber 102 after entering heating chamber 102 through passage 105. In particular, the foodstuff within the heating chamber 102 may be heated by means of the heating element 90. Optionally, a heating element 90 is provided in the housing 10 for heating foodstuff within the heating chamber 102. Further, the heating member 90 may be disposed within the base 11. For example, the heating element 90 may be disposed within the heating cavity 102 or may be disposed outside of the heating cavity 102. For example, the base 11 may include a hot tube 13, the hot tube 13 forming the heating cavity 102. The heating member 90 may be a heating coil that is wound around the outer circumference of the hot feed pipe 13 in the longitudinal direction of the hot feed pipe 13 to heat the hot feed pipe 13. The foodstuff in the heating chamber 102 is heated by the hot-water pipe 13. Heating element 90 may be electrically connected to electronic control board 70, and electronic control board 70 may control heating element 90 to turn on or turn off heating.

As shown in fig. 5, the feeder 1 may include a temperature detection sensor 110 and a feeding mechanism 120. The temperature detection sensor 110 may be used to detect the heating temperature of the food stuff by the heating member 90. The feeding mechanism 120 may be used to convey the heated foodstuff to the outside.

After the heating element 90 heats the inside of the heating chamber 102, the heating temperature can be detected by the temperature detection sensor 110. Specifically, the temperature detection sensor 110 may be provided to the housing 10. Further, the temperature detection sensor 110 may be provided in the base 11. For example, the temperature detection sensor 110 may be disposed within the heating chamber 102, or an external wall of the heating chamber 102. A probe of a temperature sensor may be disposed within heating cavity 102. Specifically, the temperature detecting sensor 110 may be fixed to an outer side wall of the heat pipe 13, and a probe of the temperature detecting sensor 110 may extend into the heating cavity 102.

The temperature detection sensor 110 is used to detect the temperature of the heating chamber 102 such that the heating element 90 stops heating when the temperature detection sensor 110 detects that the temperature of the heating chamber 102 is greater than or equal to a preset value. Specifically, the temperature detection sensor 110 is electrically connected to the electronic control board 70. The electronic control board 70 can control the operation of the temperature detection sensor 110 and can also acquire the temperature detected by the temperature detection sensor 110. The electronic control board 70 controls the heating element 90 to stop heating when the temperature detection sensor 110 detects that the temperature of the heating cavity 102 is higher than a preset value. The preset value can be set according to actual conditions. Of course, the electric control board 70 can also control the heating time of the heating member 90 to stop heating the heating member 90.

As shown in fig. 5, the second switch assembly 140 may include a second electromagnet 141 and a second blocking piece 142. The second blocking piece 142 is connected to the second electromagnet 141, for example, the second blocking piece 142 is fixedly connected to a push-pull rod of the second electromagnet 141. The second blocking piece 142 is movably disposed in the heating cavity 102, and the second electromagnet 141 is configured to push and pull the second blocking piece 142, so that the second blocking piece 142 opens or blocks the discharging hole 103. Specifically, when the second electromagnet 141 works, the push-pull rod thereof can perform telescopic motion, and further can push and pull the second blocking piece 142, so that the second blocking piece 142 can open or block the discharge hole 103. Here, the second plugging member 142 may be partially or completely opened when the discharge port 103 is opened, and only the discharge function is required. The second blocking member 142 is, for example, plate-shaped and sized to block the discharge hole 103.

The second electromagnet 141 can be electrically connected to the electronic control board 70, and the operation of the second electromagnet 141 is controlled by the electronic control board 70. For example, after controlling the heating member 90 to stop heating, the electronic control board 70 controls the second electromagnet 141 to pull the second blocking member 142 to move backward, so that the discharge hole 103 is opened, and the heated foodstuff can be output to the outside through the discharge hole 103.

Foodstuff within heating chamber 102 may be conveyed by feed mechanism 120. Alternatively, the feeding mechanism 120 may be provided in the housing 10. The feeding mechanism 120 is used for conveying the foodstuff in the heating chamber 102 out of the housing 10 for the pet to eat. Specifically, the feeding mechanism 120 may transport the foodstuff in the heating chamber 102 to the outside through the discharge hole 103 for the pet to use. By providing the feeding mechanism 120, automatic feeding can be realized.

As shown in fig. 5, the feeding mechanism 120 may include a push rod 121 and a feeding motor 122. The feeding motor 122 is in transmission connection with the push rod 121. A push rod 121 is movably inserted into the heating cavity 102. The feeding motor 122 is used for driving the pushing rod 121 to reciprocate so as to push foodstuff in the heating chamber 102 out of the casing 10. For example, one end of the hot material pipe 13 is the discharge hole 103, and the push rod 121 is movably inserted into the other end of the hot material pipe 13. The push rod 121 can push the foodstuff to the discharge hole 103, so that the foodstuff is output through the discharge hole 103.

Specifically, the outer wall of the push rod 121 may be provided with a first straight tooth portion (shown in fig. 5, but not labeled) disposed along the length direction thereof. The output shaft of the feed motor 122 may be connected to a gear (shown in fig. 5, but not labeled) that meshes with the first spur gear. During the rotation process, the feeding motor 122 can drive the push rod 121 to reciprocate in the extending direction thereof through the meshing of the gear and the first straight tooth part. Specifically, the feeding motor 122 may be turned over after driving the push rod 121 to reach a limited stroke, and drive the push rod 121 to return to the original position.

The feed motor 122 may be electrically connected to the electronic control board 70. The electronic control board 70 can control the operation of the feeding motor 122, such as forward and reverse rotation. After the heating of the heating member 90 is completed and the heating is stopped, the electric control board 70 may control the second electromagnet 141 to pull the second blocking member 142 to retreat, so that the discharge hole 103 is opened. The electric control board 70 further controls the feeding motor 122 to drive the pushing rod 121 to push the foodstuff toward the discharge hole 103, so that the foodstuff can be output through the discharge hole 103.

Based on the above description, the following exemplarily describes the operation of the feeder 1.

(1) Process for heating and feeding foodstuff

First, the lid 12 can be taken out, the foodstuff can be added into the storage chamber 101, and the lid 12 can be closed after the addition is completed.

Next, the feeding function of the feeder 1 is started (e.g. by a mobile terminal, a remote controller, or a physical button), the first blocking piece 132 is driven by the first electromagnet 131 to move back, and the first blocking piece 132 opens the channel 105.

After the passage 105 is opened, the stirring member 20 can be started to operate by the driving motor 41. One of the main functions of the stirring element 20 is to stir foodstuff, which can be pushed into the channel 105 from the storage chamber 101, and can enter the heating chamber 102 through the channel 105.

When the foodstuff in the heating chamber 102 reaches a certain amount (specifically, the foodstuff in the heating chamber 102 is considered to reach a certain amount from the side through the power-on operation time of the first electromagnet 131, for example, the time for the first blocking piece 132 to open the channel 105 is 3min, it is considered to be sufficient for the heating chamber 102 to accumulate a corresponding amount of foodstuff, which can be measured or adjusted through experiments, of course, an infrared sensor may also be arranged in the heating chamber 102 to detect the amount of the foodstuff in the heating chamber 102), the first blocking piece 132 is driven by the first electromagnet 131 to advance, and at this time, the first blocking piece 132 closes the channel 105.

The heating element 90 may be activated to heat foodstuff within the heating chamber 102. When the heating element 90 heats the foodstuff in the heating chamber 102 for a preset time or the temperature detection sensor 110 detects that the temperature is greater than or equal to a preset value, the heating element 90 stops operating. The second electromagnet 141 starts to work to drive the second plugging piece 142 to retreat and open the discharge hole 103.

The push rod 121 moves forward under the driving of the feeding motor 122, and pushes foodstuff into the feeding trough 500 through the discharge hole 103 until the push rod 121 reaches a limited stroke and stops. After the push rod 121 reaches the limited stroke, the feeding motor 122 rotates reversely to drive the push rod 121 to return to the original position. At this time, the second blocking member 142 may close the discharge hole 103 by the driving of the second electromagnet 141.

The foodstuff in the storage chamber 101 can be fed with the batch heating through the above process.

(2) Foodstuff storage process

When the foodstuff is put into the storage chamber 101, if the foodstuff is not needed to be fed at this time, the feeder 1 can be started to store the foodstuff. The ultraviolet emission assembly is opened to sterilize foodstuff in the storage cavity 101. At this time, the stirring member 20 stirs the foodstuff so as to sufficiently sterilize the bacteria in the foodstuff. Because the stirring piece 20 and the vacuum pump 30 use the same driving motor 41, the vacuum pump 30 works when the actual work is stirred, and the material storage cavity 101 is vacuumized until the air in the material storage cavity is exhausted. A one-way air inlet valve 61 in the air inlet conduit 60 prevents air from entering the accumulator chamber 101.

Of course, the foodstuff storage process ultraviolet emitting assembly described above may also be used during the heating feeding of foodstuff.

To sum up, this embodiment can reduce the humidity in the storage cavity more effectively, avoids the foodstuff to wet as far as possible, can realize once storage, feed many times effectively, can need not to arrange two actuating mechanism for stirring piece and vacuum pump moreover, and the structure is simpler and can effectively reduce the cost, can also practice thrift the space of feeder.
