Description

Technical Field

[0001] The invention relates to an onboard catering device, in particular to an onboard catering device used on a fighter plane. Background Art

[0002] The atmosphere is divided into the exosphere, thermosphere, mesosphere, stratosphere, and troposphere. Aircraft mainly fly in the troposphere and stratosphere. The troposphere is the lowest layer, where weather changes are the most complex and has the greatest impact on flight safety. Various emergencies encountered during flight occur in the troposphere, such as atmospheric streams, snow, rain, low cloud curtains, etc. The stratosphere is above the troposphere. The advantage of the stratosphere is that the airflow is stable and relatively safe, but the disadvantage is that the oxygen is thin. Aircraft generally fly in the stratosphere. Oxygen, temperature, and pressure will change with increasing altitude, so fighter pilots will wear anti-gravity suits and oxygen breathing devices. In addition, the internal structure of the fighter is small, and the air pressure is low and the vibration and turbulence are large when flying at high altitudes, making it difficult for them to eat and drink water.

[0003] At present, fighter pilots mainly solve the problem of eating and drinking by carrying long-distance flight food and bottled mineral water respectively. However, when flying at high altitudes, pilots need to wear oxygen masks due to the relatively low air pressure. At the same time, the cabin space is small, and opening food packages and / or unscrewing bottled mineral water is a complicated and time-consuming process. Therefore, when the pilot eats, he needs to lower the flight altitude of the aircraft from the stratosphere to the troposphere, take off the mask, and eat. However, this way of food security is cumbersome for pilots and is not conducive to their mission execution. In addition, the complex weather in the troposphere is not conducive to flying, and the food residues, packaging or mineral water produced during the meal are easily spilled in the cabin, affecting flight safety.

[0004] In addition, on some special aircraft with larger space, the crew members' food and drinking water are mainly guaranteed by carrying thermos cups, thermos bottles and insulated lunch boxes. For example, the technical solution provided by patent CN11118680A provides an onboard food cabinet used on special aircraft, which is equipped with thermos bottles and self-heating lunch boxes to ensure the crew members' long-duration flight missions. However, this kind of dining process is also prone to produce food residues, packaging waste, or mineral water spilled in the cabin, which will affect flight safety.

[0005] If an onboard catering device can be provided that can simplify the catering process, save time, and simultaneously not generate food residues and excess packaging waste during the catering process, the above-mentioned problems can be solved to a large extent. Summary of the invention

[0006] In response to the problems and needs raised above, this solution proposes an onboard catering device, which can achieve the above technical objectives and bring about many other technical effects by adopting the following technical features.

[0007] The object of the present invention is to provide an onboard catering device, comprising:

[0008] The main body has a receiving cavity with an open end inside.

[0009] A movable part, the movable part is pivotally adapted in the accommodating cavity and can switch between an ejection position of ejecting the accommodating cavity and a contraction position of contracting in the accommodating cavity, wherein a fluid ball is placed on the movable part, the interior of the fluid ball is drinking water or liquid high-energy food, and the exterior thereof is an edible film;

[0010] The cover body is disposed on the open end and is detachably connected to the main body.

[0011] In this technical solution, when the driver needs to eat, he first opens the cover body so that the accommodating cavity of the main body is opened, and under the action of external force, the movable part is driven to move from the retracted position to the ejection position. At this time, the fluid ball extends out of the accommodating cavity and is taken out for eating. After eating, the movable part is driven to the retracted position in the accommodating cavity, and the fluid ball is stored in the accommodating cavity covered and encapsulated by the cover body. The onboard catering device can simplify the eating process and save time, and at the same time, no food residue and excess packaging waste is generated during the eating process.

[0012] In addition, the onboard catering device according to the present invention may also have the following technical features:

[0013] In an example of the present invention, a plurality of grooves are formed in the movable portion, and the fluid balls are fitted in the grooves.

[0014] In one example of the present invention, the present invention further includes: a baffle portion,

[0015] The baffle portion is arranged at the open end of the main body portion, and is provided with through holes, the number of which corresponds to the number of the fluid balls. When the movable portion rotates so that the fluid balls correspond one-to-one with the through holes, the movable portion moves to the ejection position so that the fluid balls fit into the through holes.

[0016] In one example of the present invention, the movable part comprises:

[0017] Body box;

[0018] A pressing block is arranged at the lower end of the main body box;

[0019] The connecting shaft is provided through the connecting hole on the main body and penetrates through the bottom wall thereof, and connects the main body box and the pressing block.

[0020] In one example of the present invention, the movable part further includes:

[0021] The elastic member has one end connected to the movable part and the other end connected to the main body, and is configured so that when the movable part is in the ejection position, the movable part has a tendency to return to the contracted position.

[0022] In one example of the present invention, it further includes: a limiting portion,

[0023] The limiting portion is connected to the movable portion, and is configured to limit the position of the movable portion when the movable portion is in the ejection position.

[0024] In one example of the present invention, the limiting portion includes:

[0025] At least one deformation bar, the deformation bar is in an arc-shaped structure and is arranged along the extension direction of the connecting shaft, and one end of the deformation bar close to the pressing block is fixedly connected to the connecting shaft, and one end of the deformation bar close to the main box is arranged in contact with the connecting shaft, and the middle part of the deformation bar protrudes in the radial direction away from the connecting shaft;

[0026] When the movable part is required to move to the ejection position, the connecting hole squeezes the middle part of the deformation strip to make it contact with the connecting shaft, and the end of the deformation strip close to the body box opens in a radial direction away from the connecting shaft to fix the position of the movable part;

[0027] When the movable part needs to move to the retracted position, the connecting hole squeezes the end of the deformation strip close to the body box to make it contact with the connecting shaft, and the middle part of the deformation strip moves away from the radial direction of the connecting shaft to retract to the initial position.

[0028] In an example of the present invention, the deformation strips include a plurality of deformation strips which are spaced apart along the circumferential direction of the connecting axis.

[0029] In an example of the present invention, the deformation strip is a metal elastic member.

[0030] In one example of the present invention, the main body includes, from outside to inside, a plastic spraying layer, a thermal insulation layer and an aluminum plate layer, wherein the plastic spraying layer, the thermal insulation layer and the aluminum plate layer are adhered to each other by an adhesive.

[0057] According to an onboard catering device 100 of the present invention, Figures 1 to 4 As shown, including:

[0058] The main body 110 has a receiving cavity 111 with an open end.

[0059] The movable part 120 is pivotally adapted in the accommodating cavity 111 and can switch between an ejection position of ejecting the accommodating cavity 111 and a contraction position of contracting in the accommodating cavity 111, wherein a fluid ball 200 is placed on the movable part 120, the fluid ball 200 contains drinking water or liquid high-energy food, and the fluid ball 200 has an edible film on the outside;

[0060] The cover portion 130 is disposed on the open end and is detachably connected to the main body 110 .

[0061] That is to say, when the pilot needs to eat, he first opens the cover body 130 so that the accommodating cavity 111 of the main body 110 is opened, and under the action of external force, the movable part 120 is driven to move from the retracted position to the ejected position. At this time, the fluid ball 200 extends out of the accommodating cavity 111 and is taken out for eating. After eating, the movable part 120 is driven to the retracted position in the accommodating cavity 111, and the fluid ball 200 is stored in the accommodating cavity 111 covered and packaged by the cover body 130; the onboard catering device 100 can simplify the eating process and save time, and at the same time, no food residue and excess packaging waste are generated during the eating process.

[0062] In one example of the present invention, a plurality of grooves 1211 are formed in the movable portion 120 , and the fluid ball 200 is adapted to fit in the grooves 1211 ;

[0063] By providing a plurality of grooves 1211 in the movable portion 120 , the fluid ball 200 can be fixed, so that the fluid ball 200 is more stable in the accommodating cavity 111 .

[0064] In one example of the present invention, the invention further includes: a baffle portion 140,

[0065] The baffle portion 140 is disposed at the open end of the main body portion 110, and a through hole 141 is disposed on the baffle portion 140. The number of the through holes 141 corresponds to the number of the fluid balls 200. When the movable portion 120 rotates so that the fluid balls 200 correspond to the through holes 141 one by one, the movable portion 120 moves to the ejection position so that the fluid balls 200 fit into the through holes 141.

[0066] In order to further make the fluid ball 200 more stable, a baffle is provided at the open end of the main body 110. When the driver does not need to eat or drink, the movable part 120 is rotated so that the fluid ball 200 corresponds to the position of the non-through hole 141 of the baffle, thereby further limiting the position of the fluid ball 200. When the driver needs to eat, the movable part 120 is rotated to a position where the fluid ball 200 corresponds to the through hole 141 one by one, and the movable part 120 is driven to move to the ejection position under the action of an external force so that the fluid ball 200 fits with the through hole 141 and extends out of the accommodating cavity 111.

[0067] In one example of the present invention, the movable part 120 includes:

[0068] Body box 121;

[0069] A pressing block 123 is disposed at the lower end of the main body box 121;

[0070] A connecting shaft 122 is provided through a connecting hole 112 on the main body 110 and passes through the bottom wall thereof, and connects the main body box 121 and the pressing block 123;

[0071] Specifically, a hidden groove 113 is opened at the lower end of the main body 110, and the pressing block 123 is adapted in the hidden groove 113; the connecting shaft 122 and the main body box 121 and the pressing block 123 are fastened together by threads, and the pressing block 123 is pressed to move in the hidden groove 113 to realize the synchronous up and down movement of the main body box 121, that is, movement to the uppermost end is the ejection position, and movement to the lowermost end is the retracted position; the above structure is hidden at the lower end of the main body 110, which is convenient to operate and compact in structure, and will not occupy other space.

[0072] In one example of the present invention, the movable part 120 further includes:

[0073] An elastic member 124, one end of which is connected to the movable portion 120, and the other end of which is connected to the main body 110, and is configured to make the movable portion 120 have a tendency to return to the retracted position when the movable portion 120 is in the ejected position;

[0074] Preferably, the elastic member 124 is one of a compression spring, a tension spring and a spring sheet;

[0075] For example, when the elastic member 124 is a compression spring;

[0076] The compression spring is sleeved on the connecting shaft 122 and installed between the bottom wall of the hidden groove 113 and the pressing block 123. When the driver needs to eat, he first opens the cover body 130 so that the accommodating cavity 111 of the main body 110 is opened, and the movable part 120 is driven to move from the retracted position to the ejected position under the action of external force. During this process, the compression spring is compressed to generate a tendency to restore to the retracted position. After the fluid ball 200 is taken out and eaten, the movable part 120 is driven by the elastic force to restore to the retracted position, and the fluid ball 200 is stored in the accommodating cavity 111 and is covered and packaged by the cover body 130.

[0077] When the elastic member 124 is a tension spring, the tension spring is installed between the bottom wall of the accommodating cavity 111 and the main body box 121. The specific principle is similar to the above and will not be repeated here. Similarly, the elastic member 124 can also achieve the above function by being a spring.

[0078] In one example of the present invention, it further includes: a limiting portion 150,

[0079] The limiting portion 150 is connected to the movable portion 120 and is configured to limit the position of the movable portion 120 when the movable portion 120 is in the ejection position;

[0080] The limiting portion 150 can be provided to limit the position of the movable portion 120 , so that the driver can eat more conveniently.

[0081] In one example of the present invention, the limiting portion 150 includes:

[0082] At least one deformation bar 151, the deformation bar 151 is in an arc-shaped structure and is arranged along the extension direction of the connecting shaft 122, and one end of the deformation bar 151 close to the pressing block 123 is fixedly connected to the connecting shaft 122, and one end of the deformation bar 151 close to the body box 121 is arranged in contact with the connecting shaft 122, and the middle part of the deformation bar 151 protrudes in the radial direction away from the connecting shaft 122;

[0083] When the movable part 120 needs to move to the ejection position, the connecting hole 112 squeezes the middle part of the deformation bar 151 to make it contact with the connecting shaft 122, and the end of the deformation bar 151 close to the body box 121 opens in a radial direction away from the connecting shaft 122 to fix the position of the movable part 120;

[0084] When the movable part 120 needs to move to the retracted position, the connecting hole 112 squeezes the end of the deformable strip 151 close to the main body box 121 to make it contact with the connecting shaft 122, and the middle part of the deformable strip 151 moves in a radial direction away from the connecting shaft 122 to retract to the initial position;

[0085] Specifically, when the driver needs to eat, he first opens the cover 130 so that the accommodating cavity 111 of the main body 110 is opened, and the movable part 120 (pressing block 123) is driven to move from the retracted position to the ejected position under the action of external force. During this process, the connecting hole 112 gradually squeezes the middle part of the deformation strip 151 to make it contact with the connecting shaft 122, and the end of the deformation strip 151 close to the main body box 121 opens in the radial direction away from the connecting shaft 122 to fix the position of the movable part 120. At this time, the fluid ball 2 00 extends out of the accommodating cavity 111 and takes out for consumption. After consumption, the movable portion 120 (pressing block 123) is driven to the retracted position in the accommodating cavity 111 under the action of external force. During this process, the connecting hole 112 gradually squeezes the end of the deformation strip 151 close to the main box 121 to make it contact with the connecting shaft 122. The middle part of the deformation strip 151 moves in a radial direction away from the connecting shaft 122 to retract to the initial position. The fluid ball 200 is stored in the accommodating cavity 111 covered and packaged by the cover body 130.

[0086] It should be noted that the deformation elastic force of the deformation strip 151 is greater than the elastic force of the elastic member 124, so as to avoid the movable part 120 from restoring its position under the elastic force of the elastic member 124 after the position is limited by the deformation strip 151; and the function of the elastic member 124 is to have a tendency to restore the initial position when the deformation strip 151 is in a non-limited state.

[0087] In one example of the present invention, the deformation strips 151 include a plurality of deformation strips 151 and are arranged at intervals along the circumferential direction of the connecting shaft 122;

[0088] By providing a plurality of deformation bars 151 , the movable portion 120 can be defined more reliably and more stably.

[0089] In an example of the present invention, the deformation bar 151 is a metal elastic member, and the deformation bar 151 can be repeatedly switched between the open position and the contracted position through a memory metal sheet.

[0090] In one example of the present invention, the main body 110 includes a plastic spraying layer, a thermal insulation layer and an aluminum plate layer from the outside to the inside, wherein the plastic spraying layer, the thermal insulation layer and the aluminum plate layer are adhered to each other by an adhesive;

[0091] The above structure can make the main body 110 have a heat-insulating effect, thereby extending the temperature preservation time of the fluid ball 200.

[0092] The exemplary implementation of the onboard catering device 100 proposed by the present invention is described in detail above with reference to the preferred embodiments. However, those skilled in the art will appreciate that, without departing from the concept of the present invention, various modifications and variations may be made to the above-mentioned specific embodiments, and various technical features and structures proposed by the present invention may be combined in various ways without exceeding the protection scope of the present invention, which is determined by the appended claims.
