Detailed implementation manners

[0095] As shown in the background art, the two fans occupy a relatively large space and have a relatively high cost.

[0096] To solve the above technical problems, the fruit and vegetable cultivation equipment provided by this application realizes external circulation and internal circulation using the same fan by controlling the connection or disconnection of different parts. Specifically, during internal circulation, the air inlet of the box body is not connected to the second area of the box body, the air outlet of the box body is not connected to the first area of the box body, and the first area is connected to the second area; the air in the second chamber flows into the second chamber through the first area and the second area in sequence. During external circulation, the air inlet is connected to the second area, the air outlet is connected to the first area, and the first area is not connected to the second area. External air flows into the second chamber through the air inlet and the second area in sequence, and the air in the second chamber flows to the outside through the first area and the air outlet in sequence.

[0104] [Overall Structure]

[0105] Figure 1 is a schematic structural diagram of the fruit and vegetable cultivation equipment provided by the embodiment of the present application. Figure 2 is a schematic structural diagram of the fruit and vegetable cultivation equipment provided by the embodiment of the present application after removing the door body. Figure 3 is a schematic structural diagram of the fruit and vegetable cultivation equipment provided by the embodiment of the present application after removing the door body and the outer shell.

[0106] See Figures 1 to 3 As shown, the fruit and vegetable cultivation equipment provided by the embodiment of the present application can form an appearance by a box body 100 and a door body 300. The box body 100 has an inner cavity, and the inner cavity has an opening. The door body 300 is used to open or close the opening.

[0107] In this embodiment, a hydroponic component 200 is arranged in the box body 100. Among them, the number of the hydroponic components 200 is at least one. When the number of the hydroponic components 200 is at least two, at least two hydroponic components 200 can be arranged at intervals along the length direction of the box body 100, so as to improve the space utilization rate of the box body 100. Exemplarily, the number of the hydroponic components 200 can be multiple, and multiple hydroponic components 200 are arranged at intervals along the length direction of the box body 100. For example, the number of the hydroponic components 200 is four. Among them, the length direction of the box body 100 is the direction shown by the Z axis.

[0108] The hydroponic component 200 is configured to hold nutrient solution and fruit and vegetable seedlings. Exemplarily, the hydroponic component 200 can cultivate leafy vegetables such as lettuce and gynura bicolor and some fruits such as strawberries, melons, and tomatoes. The liquid level of the nutrient solution in the hydroponic component 200 can be set according to the types of fruits and vegetables and the requirements of the growth period.

[0109] In some embodiments, for the convenience of observing and operating fruits and vegetables, the hydroponic component 200 is slidably connected to the box body 100, so that the hydroponic component 200 can be moved to the outside of the box body 100, facilitating user operation.

[0110] In some embodiments, the fruit and vegetable cultivation device includes a liquid supply system 700, which can be used to circulate and supply nutrient solution to the hydroponic component 200. That is to say, after the nutrient solution of the liquid supply system 700 flows to the hydroponic component 200, it flows through the flow channel of the hydroponic component 200 and then returns to the liquid supply system 700.

[0111] In some embodiments, in order to provide the light required for the growth of fruits and vegetables, the fruit and vegetable cultivation device is provided with a lighting component 800, and the lighting component 800 is arranged above the hydroponic component 200. Exemplarily, the amount of light irradiated by the lighting component 800 can be set to be similar to sunlight, and the amount of light and irradiation time most suitable for the cultivated fruits and vegetables can be set.

[0112] In some embodiments, when the number of hydroponic components 200 is at least two, at least two hydroponic components 200 can be arranged at intervals along the length direction of the box body 100, and at least two lighting components 800 are arranged in one-to-one correspondence with at least two hydroponic components 200.

[0113] In some embodiments, the lighting component 800 can be arranged at the bottom of the hydroponic component 200 above the corresponding hydroponic component 200, so that there is no need to additionally set an installation structure for the lighting component 800 in the box body 100, saving space and improving the utilization rate of space.

[0114] In some embodiments, the fruit and vegetable cultivation device includes an air conditioning device, which can include at least one of a temperature adjustment device, a humidity adjustment device, and a carbon dioxide adjustment device, so as to adjust the air condition in the box body to meet the growth requirements of fruits and vegetables. For example, the temperature adjustment device includes a refrigeration system 400 and a heating element. The carbon dioxide adjustment device can include a carbon dioxide generator.

[0115] In some embodiments, a display component is arranged outside the box body 100, and the display component can intuitively display the state of the fruit and vegetable cultivation device. In addition, for the convenience of users to set parameters, the fruit and vegetable cultivation device further includes a control panel, and the control panel is electrically connected to the controller. The control panel is a touch panel and can be set on the door body 300, or can be set on the top of the box body 100.

[0116] In some embodiments, the fruit and vegetable cultivation device includes a fan, and the fan is arranged in the box body 100. The fan drives the air to flow, thereby realizing the circulation of the air in the box body 100.

[0117] In some embodiments, the fruit and vegetable cultivation device includes a blower, which is disposed inside the box body 100. The blower drives the air to flow, thereby realizing the circulation of the air between the box body 100 and the external air.

[0118] [Door structure]

[0119] See Figure 1 and Figure 2 As shown, the door body 300 is connected to the box body 100 to open or close the opening of the box body 100. The hydroponic assembly 200 is located in the space formed by the box body 100 and the door body 300, and the hydroponic assembly 200 is not likely to affect the living environment.

[0120] In some embodiments, the door body 300 can be hinged to the box body 100, and the door body 300 rotates relative to the box body 100 to open or close the opening of the box body 100.

[0121] In other embodiments, the door body 300 can be slidably connected to the box body 100, and the door body 300 slides relative to the box body 100 to open or close the opening of the box body 100.

[0122] In some embodiments, at least a part of the door body 300 has a structure that can be seen through. In this way, the growth state of the fruits and vegetables can be observed even when the door body 300 is in a closed state.

[0123] In some embodiments, the door body 300 may include a door frame that forms an outer periphery and has an opening in the central part, and a door panel for covering the opening of the door frame. The door panel can be formed of glass or transparent plastic material.

[0124] In some embodiments, the door panel can have a color or be coated with a colored coating, metal deposition, or attached film, so that the inside of the box body 100 can be selectively visible or invisible. For example, in the state where the door body 300 is closed, if the lighting assembly 800 is turned on, the inside of the box body 100 is illuminated, and thus the inside can be seen through the door panel. On the contrary, in the state where the door body 300 is closed, if the lighting assembly 800 is turned off, the inside of the box body 100 becomes dark, and thus the inside of the box body cannot be seen through the door panel. With this structure, the growth state of the fruits and vegetables can be observed even when the door body 300 is closed. Moreover, when observation is not required, a neat appearance state can be maintained.

[0125] [Box body structure]

[0126] Figure 4 FIG. is a schematic structural view of the first box body in the fruit and vegetable cultivation device provided by the embodiment of the present application.

[0127] See Figure 4 As shown, in some embodiments, to realize the air circulation inside the box body 100, the box body 100 is configured with a first chamber 110 and a second chamber 120.

[0128] The box body 100 is configured with a first air return opening 1621 and a first air outlet 1622. The first air return opening 1621 is communicated with the first chamber 110 and is also communicated with the second chamber 120. The first air outlet 1622 is communicated with the first chamber 110 and is also communicated with the second chamber 120.

[0129] The fan 600 is disposed in the first chamber 110 or the second chamber 120. When the fan 600 rotates, it drives the air in the first chamber 110 to flow through the first air outlet 1622 into the second chamber 120, and the air in the second chamber 120 flows through the first air return opening 1621 into the first chamber 110.

[0130] In some embodiments, in order to improve the space utilization rate, the hydroponic component 200 is disposed in the second chamber 120, and the fan 600 is disposed in the first chamber 110.

[0131] In some embodiments, in order to adjust the air in the second chamber 120 to meet the needs of fruit and vegetable growth, an air conditioning device is disposed in the first chamber 110.

[0132] Specifically, the air conditioning device may include a refrigeration system. The evaporator 410 of the refrigeration system is disposed in the first chamber 110 to cool the air in the first chamber 110. The cooled air flows into the second chamber 120 under the action of the fan 600.

[0133] It can be understood that the evaporator 410 of the refrigeration system can also be used to reduce the humidity of the air in the first chamber 110. The dehumidified air flows into the second chamber 120 under the action of the fan 600.

[0134] In some embodiments, the box body 100 includes a compressor compartment. The compressor and the condenser of the refrigeration system are located in the compressor compartment. The compressor compartment is located at the bottom of the box body 100. Therefore, in order to facilitate the pipeline connection between the evaporator 410 and devices such as the compressor, the evaporator is located at a position close to the bottom of the first chamber 110 to reduce the distance from the compressor compartment.

[0135] In some embodiments, in order to save the space of the first chamber 110, the fan 600 is located above the evaporator 410, and the orthographic projection of the fan 600 and the evaporator 410 onto the ground coincides. It should be noted that the orthographic projection of the fan 600 and the evaporator 410 onto the ground may partially coincide or completely coincide. In this way, compared with the fan 600 and the evaporator 410 being arranged front and back along the depth direction of the box body 100, the size of the first chamber 110 along the depth direction of the box body 100 can be reduced, so that the size of the second chamber 120 can be increased.

[0136] In some embodiments, the air conditioning device may include a heating element disposed in the first chamber 110 to heat the air in the first chamber 110. The heated air flows into the second chamber 120 under the action of the blower 600.

[0137] It can be understood that the heating element can also accelerate the evaporation of moisture, thereby increasing the humidity of the air in the second chamber 120.

[0138] Exemplarily, the heating element can be a heating wire or a heating sheet.

[0139] In some embodiments, the heating element is disposed near the evaporator 410, or the heating element abuts against the evaporator 410. In this way, the frost generated during the refrigeration process of the evaporator 410 can be defrosted by the heating element. A drain pipe 500 can be provided at the bottom of the first chamber 110 to discharge the defrosting water into the evaporating dish in the compressor compartment.

[0140] In some embodiments, the air conditioning device further includes a carbon dioxide generator located in the first chamber 110. The carbon dioxide generator is used to generate carbon dioxide to meet the growth requirements of fruits and vegetables.

[0141] In some embodiments, the first air return opening 1621 and the first air outlet 1622 are spaced apart along the length direction of the cabinet. The first air return opening 1621 is located above the first air outlet 1622. Since heat is generated during the growth process of fruits and vegetables and heat is generated when the lighting component works, the hot air in the second chamber 120 moves upward. In this way, under the action of the blower and the rising hot air, the efficiency of air circulation is relatively high, which is beneficial to energy conservation.

[0142] In some embodiments, the number of the first air outlets 1622 is at least two. The first air return opening 1621 and at least two first air outlets 1622 are spaced apart along the length direction of the cabinet 100. The first air return opening 1621 is located on one side of at least two first air outlets 1622 along the length direction of the cabinet. For example, the first air return opening 1621 is located above at least two first air outlets 1622 along the length direction of the cabinet 100. Or, the first air return opening 1621 is located below at least two first air outlets 1622 along the length direction of the cabinet 100.

[0143] Under the action of the blower 600 in the cabinet 100, the air in the second chamber 120 returns to the second chamber 120 through the first air return opening 1621, the first chamber 110, and the first air outlet 1622 in sequence.

[0144] It can be understood that since the distances from different first air outlets 1622 to the first air return opening 1621 are different, when the air output of each first air outlet 1622 is the same, for the first air outlet 1622 closer to the first air return opening 1621, the air return path is shorter and the air return speed is faster, while for the first air outlet 1622 farther from the first air return opening 1621, the air return path is longer, and when the air volume is small, it is not easy to return the air in the distance to the first air return opening 1621, resulting in poor air uniformity in the second chamber 120.

[0145] Therefore, in this embodiment, in order to improve the air uniformity in the second chamber 120. In the direction from far away from the first air return opening 1621 to close to the first air return opening 1621, the air output of the first air outlets 1622 gradually decreases.

[0146] In some embodiments, among two adjacent first air outlets 1622, the air output of the one farther from the first air return opening 1621 is 1.1 - 3 times that of the other. It can be understood that when the air output of the one farther from the first air return opening 1621 is less than 1.1 times that of the other, it is easy for the first air outlet 1622 farther from the first air return opening 1621 to have poor air return. When the air output of the one farther from the first air return opening 1621 is more than 3 times that of the other, on the premise of ensuring smooth air return of the nearest first air outlet 1622, the required total air volume is relatively large, which is not conducive to energy conservation and cost reduction.

[0147] Exemplarily, among two adjacent first air outlets 1622, the air output of the one farther from the first air return opening 1621 is 1.2 - 2 times that of the other. Or, among two adjacent first air outlets 1622, the air output of the one farther from the first air return opening 1621 is 1.1 - 2.5 times that of the other. Or, among two adjacent first air outlets 1622, the air output of the one farther from the first air return opening 1621 is not more than 3 times that of the other. Or, among two adjacent first air outlets 1622, the air output of the one farther from the first air return opening 1621 is not less than 1.1 times that of the other.

[0148] Exemplarily, when the number of first air outlets 1622 is 3, in the direction from far away from the first air return opening 1621 to close to the first air return opening 1621, the ratio of the air outputs of the first air outlets 1622 is 5:3:2.

[0149] In a possible implementation manner, in the direction from far away from the first air return opening 1621 to close to the first air return opening 1621, the opening sizes of the first air outlets 1622 gradually decrease.

[0150] Figure 5 It is a schematic structural diagram of the air distribution structure in the fruit and vegetable cultivation equipment provided by the embodiments of the present application. Figure 6A cross-sectional view of the air distribution structure in the fruit and vegetable cultivation device provided by the embodiment of the present application.

[0151] See Figures 4 to 6 As shown, in another possible implementation, it further includes an air distribution structure 900. The air distribution structure 900 is located in the first chamber 110 and is configured to change the air volume output from the first air outlet 1622, so that in the direction from far away from the first air return opening 1621 to close to the first air return opening 1621, the air volume output from the first air outlet 1622 gradually decreases.

[0152] It can be understood that during the growth process of fruits and vegetables, it is easy to block the first air outlet 1622, thus affecting the opening size of the first air outlet 1622. In this application, the air distribution structure 900 is used to change the air volume output from the first air outlet 1622. The air distribution structure 900 is located in the first chamber 110, and the air volume output is not easily affected by fruits and vegetables.

[0153] In some embodiments, the air distribution structure 900 includes a wind blocking part 910 and a ventilation part 920. Part of the air entering the first chamber 110 through the first air return opening 1621 is guided by the wind blocking part 910 and then flows to the second chamber 120 through the opposite first air outlet 1622, and part of the air flows towards the adjacent first air outlet 1622 through the ventilation part 920. In this way, the structure of the air distribution structure 900 is relatively simple, the cost is low, and the occupied space is small.

[0154] It can be understood that the number of the air distribution structures 900 can be equal to the number of the first air outlets 1622, and the air distribution structures 900 are arranged in one-to-one correspondence with the first air outlets 1622. Or, the number of the air distribution structures 900 can be one less than the number of the first air outlets 1622, and no air distribution structure 900 is provided at the first air outlet 1622 closest to the first air return opening 1621.

[0155] In some embodiments, in order to improve the smoothness of air flow, the wind blocking part 910 includes a connecting section 911, an arc section 912, and an extending section 913 that are connected in sequence.

[0156] Among them, the connecting section 911 is connected to the inner wall of the first chamber 110 on the side facing the second chamber 120, and the connecting section 911 is located on the side of the first air outlet 1622 away from the first air return opening 1621. Among them, the side of the arc section 912 away from the first air return opening 1621 is connected to the connecting section 911, the extending section 913 is connected to the side of the arc section 912 away from the connecting section 911, the extending section 913 has a spacing from the inner wall of the first chamber 110 on the side facing the second chamber 120, the extending section 913 is opposite to the first air outlet 1622, and extends to the side of the first air outlet 1622 facing the first air return opening 1621.

[0157] Air flows toward the arc section 912 through the gap between the extension section 913 and the inner wall of the first chamber 110 facing the second chamber 120, and moves to the second chamber 120 through the first air outlet 1622 opposite to the extension section 913 under the guiding action of the arc section 912.

[0158] In some embodiments, the ventilation part 920 is located on the side of the wind shielding part 910 away from the first air outlet 1622. The ventilation part 920 includes a ventilation opening, and the extension section 913 and the inner wall of the first chamber 110 form the ventilation opening. In this way, the occupied space is relatively small.

[0159] It can be understood that, in the cross-section perpendicular to the length direction of the box body 100, the ratio of the opening size of the ventilation opening to the opening size of the air duct of the first chamber 110 affects the air volume output of the first air outlet 1622 corresponding to the air distribution structure 900.

[0160] In some embodiments, along the length direction of the box body 100, the opening size of the air duct of the first chamber 110 gradually decreases in the air flow direction.

[0161] Figure 7 This is a schematic structural diagram of the second box body in the fruit and vegetable cultivation equipment provided by the embodiments of the present application.

[0162] In some embodiments, the first chamber 110 and the second chamber 120 are arranged side by side along the depth direction of the box body 100, or the first chamber 110 and the second chamber 120 are arranged side by side along the width direction of the box body 100. Hereinafter, taking the example that the first chamber 110 and the second chamber 120 are arranged side by side along the depth direction of the box body 100 for illustration, in order to make the size of the second chamber 120 larger, the size of the first chamber 110 along the depth direction of the box body 100 is smaller. For example, the size of the first chamber 110 along the depth direction of the box body 100 is 10 to 30 cm.

[0163] Therefore, when the evaporator 410 or the heating element works, the cold quantity of the evaporator 410 or the heat of the heating element is easily directly transferred to the second chamber 120 through the box body 100, resulting in local overcooling or overheating in the second chamber 120.

[0164] To solve the above technical problems, in some embodiments, the box body 100 is configured with a first chamber 110, a second chamber 120 and a third chamber 163. The third chamber 163 is located between the first chamber 110 and the second chamber 120, and the third chamber 163 includes a return air area 1631 and an air outlet area 1632 that are separated from each other. That is to say, the return air area 1631 and the air outlet area 1632 are not connected.

[0165] The housing 100 is configured with a first air return opening 1621 and at least two spaced-apart first air outlet openings 1622. The first air return opening 1621 communicates the second chamber 120 with the air return area 1631, and the first air outlet openings 1622 communicate the second chamber 120 with the air outlet area 1632.

[0166] The housing 100 is configured with a second air return opening 1611 and a second air outlet opening 1612. The second air return opening 1611 communicates the first chamber 110 with the air return area 1631, and the second air outlet opening 1612 communicates the first chamber 110 with the air outlet area 1632.

[0167] The fan 600 is located inside the housing 100. Exemplarily, the fan 600 can be located in the first chamber 110, or the air return area 1631, or the air outlet area 1632, etc. Under the action of the fan 600, the air in the second chamber 120 flows back into the second chamber 120 in sequence through the first air return opening 1621, the air return area 1631, the second air return opening 1611, the first chamber 110, the second air outlet opening 1612, the air outlet area 1632, and the first air outlet openings 1622.

[0168] The hydroponic component 200 is spaced apart and arranged in the second chamber 120. The temperature regulating device is arranged in the first chamber 110.

[0169] It can be understood that by providing the third chamber 163, the uniformity of the distribution of the first air outlet openings 1622 can be improved. The following takes the example where the first air return opening 1621 is located above at least two first air outlet openings 1622 along the length direction of the housing 100 for illustration. When the third chamber 163 is provided, the air in the second chamber 120 enters the first chamber 110 through the first air return opening 1621, the air return area 1631, and the second air return opening 1611, moves downward along the first chamber 110, then enters the air outlet area 1632 through the second air outlet opening 1612, then moves upward along the air outlet area 1632, and enters the second chamber 120 through the first air outlet openings 1622. When the third chamber 163 is not provided, the air in the second chamber 120 enters the first chamber 110 through the first air return opening 1621, moves downward along the first chamber 110, moves to the position of the first air outlet openings 1622, and enters the second chamber 120 through the first air outlet openings 1622. That is to say, the first air outlet openings 1622 can only be arranged at the lower part of the first chamber 110, and an air regulating device is arranged at the upper part of the first chamber 110. Therefore, by providing the third chamber 163, the uniformity of the distribution of the first air outlet openings 1622 can be improved, and when the size of the second chamber 120 along the length direction of the housing is fixed, the number of the first air outlet openings 1622 that can be arranged can be increased.

[0170] It can be understood that, referring to Figure 7As shown, in some embodiments, the housing 100 is constructed with at least two first air outlets 1622 arranged at intervals. At least two hydroponic components 200 are arranged in the second chamber 120, and at least two first air outlets 1622 are arranged in a one-to-one correspondence with at least two hydroponic components 200. The varieties of fruits and vegetables cultivated in each hydroponic component 200 are different, or the fruits and vegetables of the same variety in different growth periods are cultivated in each hydroponic component. That is to say, in some cases, the fruits and vegetables in each hydroponic component 200 have different requirements for heat, humidity or carbon dioxide. Therefore, a wind distribution structure 900 can be set in the air outlet area 1632, and the wind distribution structure 900 is configured to change the air outlet volume of the first air outlet 1622. In this way, the wind distribution structure 900 is arranged in the air outlet area 1632, which can effectively avoid affecting the air outlet volume of the first air outlet 1622 due to the obstruction of fruits and vegetables, and affecting the accuracy of air outlet volume control.

[0171] In some embodiments, the wind splitting structure 900 includes a wind shielding portion 910 and a ventilation portion 920. Part of the air entering the wind outlet area 1632 through the second air outlet 1612 is guided by the wind shielding portion 910 and flows to the second chamber 120 through the opposite first air outlet 1622, and part of the air flows toward the adjacent first air outlet 1622 through the ventilation portion 920. In this way, the wind splitting structure 900 has a simpler structure and occupies a smaller space, which is conducive to reducing the occupied space of the third chamber 163.

[0172] In some embodiments, see Figure 5 and Figure 6 As shown, in order to make the air flow smooth, the wind shield 910 includes a connecting section 911, an arc section 912 and an extension section 913 connected in sequence. The connecting section 911 is connected to the inner wall of the third chamber 163 facing the second chamber 120, and the connecting section 911 is located on the side of the first air outlet 1622 away from the second air outlet 1612. The side of the arc section 912 away from the second air outlet 1612 is connected to the connecting section 911, and the extension section 913 is connected to the side of the arc section 912 away from the connecting section 911. The extension section 913 is spaced from the inner wall of the third chamber 163 facing the second chamber 120, and the extension section 913 is opposite to the first air outlet 1622 and extends to the side of the first air outlet 1622 facing the second air outlet 1612.

[0173] In some embodiments, the ventilation portion 920 is located on a side of the wind shielding portion 910 away from the first air outlet 1622. The ventilation portion 920 includes a vent, and the extension section 913 and the inner wall of the third chamber 163 form the vent. In this way, the structure is simpler and occupies less space.

[0174] It can be understood that, in a cross-section perpendicular to the length direction of the box body 100, the ratio of the opening size of the ventilation opening to the opening size of the air duct in the air outlet area 1632 affects the air volume of the first air outlet 1622 corresponding to the air distribution structure 900.

[0175] In some embodiments, along the length direction of the box body 100, the opening size of the air duct in the air outlet area 1632 gradually decreases along the air flow direction.

[0176] In some embodiments, in order to adjust the air volume of the first air outlet 1622 as needed, the ventilation part 920 further includes a moving part, which is movably connected to the wind blocking part 910. The moving part moves relative to the wind blocking part 910 to block at least part of the ventilation opening or open the ventilation opening. Exemplarily, the moving part can be rotatably connected or slidably connected to the wind blocking part 910.

[0177] In some embodiments, in order to improve the air conditioning efficiency and effect on the air in the second chamber 120, the blower 600 is located in the first chamber 110 and is opposite to the second air return opening 1611. The air conditioning device is located below the blower 600, and the second air outlet 1612 is located below the air conditioning device.

[0178] In some embodiments, an arc-shaped guiding part is provided at the bottom of the second air outlet 1612, and the arc-shaped guiding part is used to guide the air to flow obliquely upward to enter the air outlet area 1632. Among them, the projection length of the arc-shaped guiding part in the vertical direction should not be less than the projection length of the second air outlet 1612 in the vertical direction. In this way, the direction of the air flow can be efficiently guided, and the air supply efficiency can be improved.

[0179] In some embodiments, in order to effectively prevent the first air outlet 1622 from directly blowing on the roots of fruits and vegetables, which may affect the growth of fruits and vegetables. At least two first air outlets 1622 are provided in one-to-one correspondence with at least two hydroponic components 200. At least two first air outlets 1622 are respectively located above the corresponding hydroponic components 200, and the distance from the corresponding hydroponic components 200 is greater than one-third of the distance between two adjacent hydroponic components 200. Exemplarily, it is greater than half of the distance between two adjacent hydroponic components 200.

[0180] In some embodiments, at least three hydroponic components 200 are arranged at intervals along the length direction of the box body 100. The first air return opening 1621 and at least two first air outlets 1622 are arranged at intervals along the length direction of the box body. The first air return opening 1621 is located on one side of at least two first air outlets 1622 along the length direction of the box body 100.

[0181] The number of the hydroponic components 200 is the same as the sum of the numbers of the first air return openings 1621 and the first air outlet openings 1622. The first air return openings 1621 and at least two first air outlet openings 1622 are arranged in one-to-one correspondence with at least three hydroponic components 200. The first air return openings 1621 and at least two first air outlet openings 1622 are respectively located above the corresponding hydroponic components 200, and the distance from the corresponding hydroponic components 200 is greater than one-third of the distance between two adjacent hydroponic components 200. Exemplarily, it can be greater than half of the distance between two adjacent hydroponic components 200.

[0182] Figure 8 It is a schematic structural diagram of the third box body in the fruit and vegetable cultivation equipment provided by the embodiment of the present application.

[0183] See Figure 8 As shown, in some embodiments, in order to realize the circulation of the air between the box body 100 and the outside air, the box body 100 is constructed with a first chamber 110 and a second chamber 120. The first chamber 110 includes a first area 111 and a second area 112, and the first area 111 and the second area 112 are not communicated. The first area 111 is communicated with the second chamber 120, and the second area 112 is communicated with the second chamber 120. The box body 100 is constructed with an air inlet 170 and an air outlet 180. The air inlet 170 is communicated with the second area 112, and the air outlet 180 is communicated with the first area 111.

[0184] The fan 600 is arranged in the box body 100, and the fan 600 is configured to drive the air to flow. Under the action of the fan 600, the air in the second chamber 120 flows to the outside of the box body 100 through the first area 111 and the air outlet 180. The air outside the box body 100 flows into the second chamber 120 through the air inlet 170, the second area 112.

[0185] The hydroponic components 200 are arranged in the second chamber 120.

[0186] It can be understood that the first area 111 and the second area 112 are not communicated, the air inlet 170 is communicated with the second area 112, and the air outlet 180 is communicated with the first area 111, which can effectively avoid the short circuit of the air inlet, that is, the air entering through the air inlet 170 directly flows out through the air outlet 180.

[0187] Figure 9 It is a schematic structural diagram of another angle of the fruit and vegetable cultivation equipment provided by the embodiment of the present application.

[0188] See Figures 9 to 12 As shown, in some embodiments, in order to increase the distance between the air inlet 170 and the air outlet 180, an air inlet structure 1000 is further included. The air inlet structure 1000 is connected to the box body 100. The air inlet structure 1000 is configured with an air inlet duct. The outlet of the air inlet duct is communicated with the air inlet 170. The air inlet duct is bent toward the side of the air inlet 170 away from the air outlet 180.

[0189] In some embodiments, in order to increase the distance between the air inlet 170 and the air outlet 180, an air outlet structure 1200 is further included. The air outlet structure 1200 is connected to the box body. The air outlet structure 1200 is configured with an air outlet duct. The inlet of the air outlet duct is communicated with the air outlet 180. The air outlet duct is bent toward the side of the air outlet 180 away from the air inlet 170.

[0190] In some embodiments, the straight line perpendicular to the plane where the outlet of the air inlet duct is located is the first straight line, and the straight line perpendicular to the plane where the inlet of the air inlet duct is located is the second straight line. The included angle b between the first straight line and the second straight line is 5° - 60°.

[0191] It can be understood that when the included angle b between the first straight line and the second straight line is less than 5°, the increase in the distance between the air inlet 170 and the air outlet 180 is relatively small. When the included angle b between the first straight line and the second straight line is greater than 60°, the air flow is likely to be blocked.

[0192] In some embodiments, the included angle b between the first straight line and the second straight line is 10° - 30°. Or, the included angle b between the first straight line and the second straight line is greater than 5°. Or, the included angle b between the first straight line and the second straight line is less than 60°.

[0193] In some embodiments, the straight line perpendicular to the plane where the outlet of the air outlet duct is located is the third straight line, and the straight line perpendicular to the plane where the inlet of the air outlet duct is located is the fourth straight line. The included angle a between the third straight line and the fourth straight line is 5° - 60°.

[0194] It can be understood that when the included angle a between the third straight line and the fourth straight line is less than 5°, the increase in the distance between the air inlet 170 and the air outlet 180 is relatively small. When the included angle a between the third straight line and the fourth straight line is greater than 60°, the air flow is likely to be blocked.

[0195] In some embodiments, the included angle a between the third straight line and the fourth straight line is 10° - 30°. Or, the included angle a between the third straight line and the fourth straight line is greater than 5°. Or, the included angle a between the third straight line and the fourth straight line is less than 60°.

[0196] It should be noted that both the air inlet duct and the air outlet duct are uniformly transitioned arc-shaped ducts.

[0197] Figure 13Schematic diagram of the air inlet structure in the fruit and vegetable cultivation equipment provided by the embodiment of the present application.

[0198] See Figure 13 As shown, in some embodiments, to facilitate the connection between the air inlet structure 1000 and the box body 100 and improve the installation efficiency. The air inlet structure 1000 includes an air inlet structure body 1010 and a first connection part 1020 that are connected to each other. The first connection part 1020 is located on the side of the air inlet structure body 1010 facing the box body. The air inlet structure body 1010 is configured with an air inlet duct, and the first connection part 1020 is inserted into the box body 100.

[0199] In some embodiments, to effectively prevent foreign objects from entering the interior of the box body 100 through the air inlet duct, the air inlet structure 1000 further includes a plurality of first partition plates 1030. The first partition plates 1030 are arranged at intervals in the air inlet duct, and the extending direction of the first partition plates 1030 is the same as the extending direction of the air inlet duct.

[0200] In some embodiments, the first partition plate 1030 can be rotatably connected to the air inlet structure body 1010 to adjust the air inlet angle.

[0202] See Figure 14 As shown, in some embodiments, to facilitate the connection between the air outlet structure 1200 and the box body 100 and improve the installation efficiency. The air outlet structure 1200 includes an air outlet structure body 1210 and a second connection part 1220 that are connected to each other. The second connection part 1220 is located on the side of the air outlet structure body 1210 facing the box body. The air outlet structure body 1210 is configured with an air outlet duct, and the second connection part 1220 is inserted into the box body 100.

[0203] In some embodiments, to effectively prevent foreign objects from entering the interior of the box body 100 through the air outlet duct, the air outlet structure 1200 further includes a plurality of second partition plates 1230. The second partition plates 1230 are arranged at intervals in the air outlet duct, and the extending direction of the second partition plates 1230 is the same as the extending direction of the air outlet duct.

[0204] In some embodiments, the second partition plate 1230 can be rotatably connected to the air outlet structure body 1210 to adjust the air outlet angle.

[0205] See Figure 9 、 Figure 10 and Figure 15 As shown, in some embodiments, the box body 100 includes a housing 130, an inner tank 150 and an air duct assembly 160.

[0206] The housing 130 has a first opening and a second opening which are spaced apart. The inner container 150 is located inside the housing 130. The inner container 150 has a first avoidance opening and a second avoidance opening. The first avoidance opening faces the first opening, and the second avoidance opening faces the second opening.

[0207] The air duct assembly 160 is located inside the inner container 150. A first chamber 110 is formed inside the air duct assembly 160. A part of the outer wall of the air duct assembly 160 and a part of the inner wall of the inner container 150 form a second chamber 120.

[0208] The air duct assembly 160 has a first connection structure 164 and a second connection structure 165 which are spaced apart. The first connection structure 164 is inserted into the first opening through the first avoidance opening. An air inlet 170 is provided on the side of the first connection structure 164 facing away from the second chamber. The first connection part 1020 is plugged into the first connection structure 164. The second connection structure 165 is inserted into the second opening through the second avoidance opening. An air outlet 180 is provided on the side of the second connection structure 165 facing away from the second chamber. The second connection part 1220 is plugged into the second connection structure 165. In this way, the reliability of the connection between the air inlet structure 1000 and the air outlet structure 1200 and the box body 100 is relatively high, and the installation efficiency is relatively high.

[0209] Figure 16 It is a schematic structural diagram of the inner container in the fruit and vegetable cultivation equipment provided by the embodiment of the present application.

[0210] See Figure 16 As shown, in some embodiments, in order to effectively prevent the foaming material from overflowing to the outside of the box body 100 through the first avoidance opening and the first opening, the inner container 150 is provided with a first blocking portion 151. The first blocking portion 151 includes a first blocking section and a second blocking section which are communicated with each other. The first blocking section is connected to the side of the inner container 150 facing the first rear panel, and the first blocking section is communicated with the first avoidance opening. The inner cavity opening size of the first blocking section is not larger than the opening size of the first avoidance opening. The second blocking section is connected to the side of the first blocking section facing away from the inner container 150 and abuts against the first rear panel. The inner cavity opening size of the second blocking section is smaller than the opening size of the first opening. It should be noted that the inner cavity opening sizes of the first blocking section and the second blocking section are not less than the outer wall size of the first connection structure 164, so that the first connection structure 164 can be smoothly inserted into the first opening.

[0211] In some embodiments, in order to effectively prevent the foaming material from overflowing to the outside of the box body 100 through the second avoidance port and the second opening, the box 150 is provided with a second blocking portion 152, and the second blocking portion 152 includes a third blocking section and a fourth blocking section that are interconnected, the third blocking section is connected to the side of the box 150 facing the first back plate, and the third blocking section is connected to the second avoidance port, and the inner cavity opening size of the third blocking section is not larger than the opening size of the second avoidance port. The fourth blocking section is connected to the side of the third blocking section away from the box 150, and abuts against the first back plate, and the inner cavity opening size of the fourth blocking section is smaller than the opening size of the first opening. It should be noted that the inner cavity opening size of the third blocking section and the inner cavity opening size of the fourth blocking section are not smaller than the outer wall size of the second connecting structure 165, so that the second connecting structure 165 can be smoothly inserted into the second opening.

[0212] In some embodiments, to reduce the impact on the appearance, the first chamber 110 and the second chamber 120 are arranged side by side along the depth direction of the box 100, and the air inlet 170 and the air outlet 180 are located at the back of the box. The depth direction is the direction shown by the Y axis.

[0213] See also Figure 9 As shown, in some embodiments, since heat is generated during the growth of fruits and vegetables, and heat is generated when the illumination assembly 800 is working, the hot air in the second chamber 120 moves upward, and under the action of the fan 600 and the rising of the hot air, the air circulation efficiency is high, which is conducive to energy saving. Therefore, the first area 111 is located above the second area 112. The external air flows into the second chamber 120 through the air inlet 170 and the second area 112 in sequence, and the air in the second chamber 120 flows upward, and flows to the outside through the first area 111 and the exhaust port 180 in sequence.

[0214] In some embodiments, the housing 100 is configured with a first air outlet 1622 and a first air return outlet 1621. The first air outlet 1622 is in communication with both the second area 112 and the second chamber 120, and the first air return outlet 1621 is in communication with both the second chamber 120 and the first area 111. The air inlet 170 is located above the first air outlet 1622, the first air return outlet 1621 is located above the first air outlet 1622, and the air outlet 180 is located above the first air return outlet 1621.

[0215] External air enters the second area 112 through the air inlet 170, moves downward along the second area 112 to the position of the first air outlet 1622, and flows into the second chamber 120 through the first air outlet 1622. The air in the second chamber 120 flows upward and enters the first area 111 through the first air return port 1621, moves upward along the first area 111 to the position of the air exhaust port 180, and flows to the outside through the air exhaust port. In this way, under the action of the fan and the rising hot air, the circulation effect is better, the efficiency of air circulation is higher, which is beneficial to energy conservation.

[0216] In some embodiments, in order to improve the efficiency of air circulation, the fan 600 is located in the first area 111 and the fan 600 is opposite to the first air return port 1621.

[0217] In some embodiments, it further includes a temperature adjustment device, and the temperature adjustment device is arranged in the second area 112.

[0218] Specifically, the temperature adjustment device includes a refrigeration system and a heating element. The refrigeration system includes an evaporator 410. The evaporator 410 and the heating element are arranged in the second area 112, so as to adjust the temperature of the externally entering air, which is beneficial to maintaining the stability of the air in the second chamber 120.

[0219] In some embodiments, the air inlet 170 is located above the temperature adjustment device, and the first air outlet 1622 is located below the temperature adjustment device. In this way, it is beneficial for the externally entering air to fully contact the temperature adjustment device, thereby improving the temperature adjustment effect.

[0220] It can be understood that the evaporator 410 of the refrigeration system can also be used to reduce the humidity of the air in the first chamber 110. The dehumidified air flows into the second chamber 120 under the action of the fan 600.

[0221] In some embodiments, the box body 100 includes a compressor compartment 140, and the compressor 420 and the condenser of the refrigeration system are located in the compressor compartment. The compressor compartment 140 is located at the bottom of the box body 100. Therefore, in order to facilitate the pipeline connection between the evaporator 410 and devices such as the compressor 420, the evaporator 410 is located in the second area 112 to reduce the distance from the compressor compartment 140.

[0222] In some embodiments, to save the space of the first chamber 110, the blower 600 is located in the first region 111, and the orthographic projection of the blower 600 and the evaporator 410 facing the ground coincides. It should be noted that the orthographic projection of the blower 600 and the evaporator 410 facing the ground may partially coincide or completely coincide. In this way, compared with the front-back arrangement of the blower 600 and the evaporator 410 along the depth direction of the cabinet 100, the size of the first chamber 110 along the depth direction of the cabinet 100 can be reduced, so that the size of the second chamber 120 can be increased.

[0223] It can be understood that the heating element can also accelerate the evaporation of moisture, so as to increase the humidity of the air in the second chamber 120. Exemplarily, the heating element can be a heating wire or a heating sheet.

[0224] In some embodiments, the heating element is arranged at a position close to the evaporator 410, or the heating element abuts against the evaporator 410. In this way, the frost generated during the refrigeration process of the evaporator 410 can be defrosted by the heating element. A drain pipe 500 can be arranged at the bottom of the first chamber 110, so as to discharge the defrosting water into the evaporating dish in the compressor compartment.

[0225] In some embodiments, the first chamber 110 and the second chamber 120 are arranged side by side along the depth direction of the cabinet 100, or the first chamber 110 and the second chamber 120 are arranged side by side along the width direction of the cabinet 100. Hereinafter, taking the case where the first chamber 110 and the second chamber 120 are arranged side by side along the depth direction of the cabinet 100 as an example, in order to make the size of the second chamber 120 larger, the size of the first chamber 110 along the depth direction of the cabinet 100 is smaller. For example, the size of the first chamber 110 along the depth direction of the cabinet 100 is 10 to 30 cm.

[0226] Therefore, when the evaporator 410 or the heating element is working, the cold quantity of the evaporator 410 or the heat of the heating element is easily directly transferred into the second chamber 120 through the cabinet, resulting in local overcooling or overheating in the second chamber 120.

[0227] Figure 17 This is a schematic structural view of the fourth cabinet in the fruit and vegetable cultivation equipment provided by the embodiments of the present application.

[0228] To solve the above technical problems, refer to Figure 17As shown, in some embodiments, the box body is configured with a first chamber 110, a second chamber 120, and a third chamber 163. The third chamber 163 is located between the first chamber 110 and the second chamber 120. The third chamber 163 includes a return air area 1631 and an air outlet area 1632 that are separated from each other. That is to say, the return air area 1631 and the air outlet area 1632 are not connected. Both the return air area 1631 and the air outlet area 1632 are connected to the second chamber 120, and the return air area 1631 is connected to the first area 111, and the air outlet area 1632 is connected to the second area 112. The first chamber 110 includes a first area 111 and a second area 112, and the first area 111 and the second area 112 are not connected. The box body 100 is configured with an air inlet 170 and an air outlet 180. The air inlet 170 is connected to the second area 112, and the air outlet 180 is connected to the first area 111.

[0229] Under the action of the fan 600, the external air flows through the air inlet 170, the second area 112, and the air outlet area 1632 in sequence and then flows into the second chamber 120. The air in the second chamber 120 flows through the return air area 1631, the first area 111, and the air outlet 180 in sequence and then flows to the outside.

[0230] In some embodiments, the return air area 1631 is located above the air outlet area 1632. The first area 111 is located above the second area 112.

[0231] Under the action of the fan, the external air flows through the air inlet 170, the second area 112, and the air outlet area 1632 in sequence and then flows into the second chamber 120. The air in the second chamber 120 flows upward and flows through the return air area 1631, the first area 111, and the air outlet 180 in sequence and then flows to the outside.

[0232] In some embodiments, the box body 100 is configured with a first air outlet 1622 and a first return air inlet 1621. The first air outlet 1622 is connected to both the air outlet area 1632 and the second chamber 120. The first return air inlet 1621 is connected to both the return air area 1631 and the second chamber 120. The box body 100 is configured with a second air outlet 1612 and a second return air inlet 1611. The second air outlet 1612 is connected to both the second area 112 and the air outlet area 1632. The second return air inlet 1611 is connected to both the return air area 1631 and the first area 111. The air inlet 170 is located above the second air outlet 1612. The first air outlet 1622 is located above the second air outlet 1612. The first return air inlet 1621 is located above the first air outlet 1622. The second return air inlet 1611 is located below the first return air inlet 1621. The air outlet 180 is located above the second return air inlet 1611.

[0233] External air enters the second area 112 through the air inlet 170, moves downward along the second area 112 to the position of the second air outlet 1612, enters the air outlet area 1632 through the second air outlet 1612, and moves upward along the air outlet area 1632 to the position of the first air outlet 1622, and then flows into the second chamber 120 through the first air outlet 1622. The air in the second chamber 120 flows upward, enters the air return area 1631 through the first air return port 1621, moves downward along the air return area 1631 to the position of the second air return port 1611, and then flows into the first area 111 through the second air return port 1611, moves upward along the first area 111 to the position of the air discharge port 180, and then flows to the outside through the air discharge port 180. In this way, under the action of the fan 600 and the rising of hot air, the efficiency of air circulation is relatively high, which is beneficial to energy conservation.

[0234] In some embodiments, the number of the first air outlets 1622 is at least two. The first air return port 1621 and at least two first air outlets 1622 are arranged at intervals along the length direction of the box body 100, and the first air return port 1621 is located on one side of at least two first air outlets 1622 along the length direction of the box body 100. For example, the first air return port 1621 is located above at least two first air outlets 1622 along the length direction of the box body 100. Or, the first air return port 1621 is located below at least two first air outlets 1622 along the length direction of the box body 100.

[0235] Under the action of the fan 600 in the box body 100, the air in the second chamber 120 flows to the outside of the box body 100 through the first air return port 1621, the air return area 1631, the first area 111 and the air discharge port 180 in sequence.

[0236] It can be understood that since the distances from different first air outlets 1622 to the first air return port 1621 are different, when the air output of each first air outlet 1622 is the same, for the first air outlet 1622 close to the first air return port 1621, the air return path is shorter and the air return speed is faster, while for the first air outlet 1622 far from the first air return port 1621, the air return path is longer. When the air volume is small, it is not easy to return the air in the distance to the first air return port 1621, resulting in poor air uniformity in the second chamber 120.

[0237] Therefore, as shown in Figure 8 In this embodiment, in order to improve the air uniformity in the second chamber 120. From the direction far from the first air return port 1621 to the direction close to the first air return port 1621, the air output of the first air outlet 1622 gradually decreases.

[0238] In some embodiments, among two adjacent first air outlets 1622, the air volume of the one farther from the first air return opening 1621 is 1.1 - 3 times that of the other. It can be understood that when the air volume of the one farther from the first air return opening 1621 is less than 1.1 times that of the other, it is easy for the first air outlet 1622 farther from the first air return opening 1621 to have poor air return. When the air volume of the one farther from the first air return opening 1621 is greater than 3 times that of the other, on the premise of ensuring smooth air return of the nearest first air outlet 1622, the required total air volume is relatively large, which is not conducive to energy conservation and cost reduction.

[0239] Exemplarily, among two adjacent first air outlets 1622, the air volume of the one farther from the first air return opening 1621 is 1.2 - 2 times that of the other. Or, among two adjacent first air outlets 1622, the air volume of the one farther from the first air return opening 1621 is 1.1 - 2.5 times that of the other. Or, among two adjacent first air outlets 1622, the air volume of the one farther from the first air return opening 1621 is not greater than 3 times that of the other. Or, among two adjacent first air outlets 1622, the air volume of the one farther from the first air return opening 1621 is not less than 1.1 times that of the other.

[0240] Exemplarily, when the number of first air outlets 1622 is 3, in the direction from the one farther from the first air return opening 1621 to the one closer to the first air return opening 1621, the ratio of the air volumes of the first air outlets 1622 is 5:3:2.

[0241] In a possible implementation manner, in the direction from the one farther from the first air return opening 1621 to the one closer to the first air return opening 1621, the opening size of the first air outlet 1622 gradually decreases.

[0242] In another possible implementation manner, it further includes an air distribution structure 900. The air distribution structure 900 is located in the second region 112 and is configured to change the air volume of the first air outlet 1622, so that in the direction from the one farther from the first air return opening 1621 to the one closer to the first air return opening 1621, the air volume of the first air outlet 1622 gradually decreases.

[0243] It can be understood that during the growth process of fruits and vegetables, it is easy to block the first air outlet 1622, thereby affecting the opening size of the first air outlet 1622. In this application, the air distribution structure 900 is used to change the air volume of the first air outlet 1622. The air distribution structure 900 is located in the first chamber 110, and the air volume is not easily affected by fruits and vegetables.

[0244] In some embodiments, refer to Figure 5 and Figure 6As shown, the air distribution structure 900 includes a wind shield 910 and a ventilation part 920. Part of the air entering the second area 112 through the air inlet 170 is guided by the wind shield 910 and flows to the second chamber 120 through the opposite first air outlet 1622, and part of the air flows toward the adjacent first air outlet 1622 through the ventilation part 920. In this way, the air distribution structure 900 has a simpler structure, lower cost, and occupies less space.

[0245] It is understandable that the number of the air splitting structures 900 may be equal to the number of the first air outlets 1622, and the air splitting structures 900 are arranged in a one-to-one correspondence with the first air outlets 1622. Alternatively, the number of the air splitting structures 900 may be one less than the number of the first air outlets 1622, and the first air outlet 1622 closest to the first return air outlet 1621 is not provided with an air splitting structure 900.

[0246] In some embodiments, in order to improve the smoothness of air flow, the wind shielding portion 910 includes a connecting segment 911, an arc segment 912, and an extending segment 913 which are connected in sequence.

[0247] The connecting section 911 is connected to the inner wall of the second area 112 on the side facing the second chamber 120 , and the connecting section 911 is located on the side of the first air outlet 1622 away from the air inlet 170 .

[0248] Among them, the side of the arc segment 912 facing away from the air inlet 170 is connected to the connecting segment 911, the extension segment 913 is connected to the side of the arc segment 912 facing away from the connecting segment 911, the extension segment 913 is spaced apart from the inner wall of the first area 111 facing the second chamber 120, the extension segment 913 is opposite to the first air outlet 1622, and extends to the side of the first air outlet 1622 facing the air inlet 170.

[0249] The air flows toward the arc segment 912 through the gap between the extension segment 913 and the inner wall of the air outlet area 1632 toward the second chamber 120 , and moves to the second chamber 120 through the first air outlet 1622 opposite to the extension segment 913 under the guiding effect of the arc segment 912 .

[0250] In some embodiments, the ventilation portion 920 is located on a side of the wind shielding portion 910 away from the first air outlet 1622, and the ventilation portion 920 includes a vent, and the extension section 913 and the inner wall of the second area 112 form the vent. In this way, the structure is simpler and occupies less space.

[0251] It is understandable that, along a cross section perpendicular to the length direction of the box body 100 , the ratio of the opening size of the vent to the opening size of the air duct in the air outlet area 1632 affects the air volume of the first air outlet 1622 corresponding to the air distribution structure 900 .

[0252] In some embodiments, along the length direction of the cabinet 100, the opening size of the air duct in the air outlet area 1632 gradually decreases in the air flow direction.

[0253] In some embodiments, as shown Figure 17 in the figure, the cabinet 100 is configured with a first chamber 110, a second chamber 120, and a third chamber 163. The first chamber 110 includes a first area 111 and a second area 112, and the first area 111 is not communicated with the second area 112. The third chamber 163 includes a return air area 1631 and an air outlet area 1632, and the return air area 1631 is not communicated with the air outlet area 1632.

[0254] The cabinet 100 is configured with a first return air opening 1621 and at least two first air outlet openings 1622. The first return air opening 1621 and the at least two first air outlet openings 1622 are arranged at intervals along the length direction of the cabinet 100. The first return air opening 1621 is located on one side of the at least two first air outlet openings 1622 along the length direction of the cabinet 100. The first return air opening 1621 is communicated with the return air area 1631 and is also communicated with the second chamber 120. The first air outlet opening 1622 is communicated with the air outlet area 1632 and is also communicated with the second chamber 120.

[0255] The cabinet 100 is configured with a second return air opening 1611 and a second air outlet opening 1612. The second return air opening 1611 is communicated with both the first area 111 and the return air area 1631. The second air outlet opening 1612 is communicated with both the second area 112 and the air outlet area 1632.

[0256] The cabinet 100 is configured with an air inlet 170 and an air outlet 180. The air inlet 170 is communicated with both the outside of the cabinet 100 and the second area 112. The air outlet 180 is communicated with both the outside of the cabinet 100 and the first area 111.

[0257] The fan 600 is arranged inside the cabinet 100. The hydroponic component 200 is arranged inside the second chamber 120.

[0258] From the direction away from the first return air opening 1621 to the direction close to the first return air opening 1621, the air volume of the first air outlet opening 1622 gradually decreases.

[0259] It can be understood that by setting the third chamber 163, the uniformity of the distribution of the first air outlet 1622 can be improved. Hereinafter, an example will be given in which the first air return opening 1621 is located above at least two first air outlets 1622 along the length direction of the cabinet 100. When the third chamber 163 is provided, the external air enters the second region 112 through the air inlet 170, moves downward along the second region 112 to the position of the second air outlet 1612, enters the air outlet area 1632 through the second air outlet 1612, and moves upward along the air outlet area 1632 to the position of the first air outlet 1622, and flows into the second chamber 120 through the first air outlet 1622. When the third chamber 163 is not provided, the external air enters the second region 112 through the air inlet 170, moves downward along the second region 112 to the position of the first air outlet 1622, and flows into the second chamber 120 through the first air outlet 1622. That is to say, the first air outlet 1622 can only be provided at a position in the lower part of the second region 112, and a temperature adjustment device is provided at a position in the upper part of the second region 112. Therefore, by setting the third chamber 163, the uniformity of the distribution of the first air outlet 1622 can be improved, and when the size of the second chamber 120 along the length direction of the cabinet 100 is fixed, the number of the first air outlets 1622 that can be provided can be increased.

[0260] In some embodiments, a wind distribution structure 900 is further included. The wind distribution structure 900 is located in the air outlet area 1632 and is configured to change the air volume of the first air outlet 1622, so that the air volume of the first air outlet 1622 gradually decreases from the direction away from the first air return opening 1621 to the direction close to the first air return opening 1621. In this way, the wind distribution structure 900 is arranged in the air outlet area 1632, which can effectively prevent the air volume of the first air outlet 1622 from being affected by the obstruction of fruits and vegetables, and affect the accuracy of the air volume regulation.

[0261] In some embodiments, referring to Figure 5 and Figure 6 as shown, the wind distribution structure 900 includes a wind blocking part 910 and a ventilation part 920. Part of the air entering the air outlet area 1632 through the second air outlet 1612 is guided by the wind blocking part 910 and flows through the opposite first air outlet 1622 into the second chamber 120, and part of the air flows toward the adjacent first air outlet 1622 through the ventilation part 920. In this way, the structure of the wind distribution structure 900 is relatively simple and occupies a small space, which is beneficial to reducing the occupied space of the third chamber 163.

[0262] In some embodiments, in order to make the air flow smooth, the wind shield 910 includes a connecting section 911, an arc section 912, and an extension section 913 connected in sequence. The connecting section 911 is connected to the inner wall of the air outlet area 1632 facing the second chamber 120, and the connecting section 911 is located on the side of the first air outlet 1622 away from the second air outlet 1612. The side of the arc section 912 away from the second air outlet 1612 is connected to the connecting section 911, and the extension section 913 is connected to the side of the arc section 912 away from the connecting section 911. The extension section 913 is spaced from the inner wall of the air outlet area 1632 facing the second chamber 120, and the extension section 913 is opposite to the first air outlet 1622 and extends to the side of the first air outlet 1622 facing the air inlet 170.

[0263] In some embodiments, the ventilation portion 920 is located on a side of the wind shielding portion 910 away from the first air outlet 1622 , and the ventilation portion 920 includes a ventilation opening, and the extension section 913 and the inner wall of the first chamber 110 form the ventilation opening.

[0264] It is understandable that, along a cross section perpendicular to the length direction of the box body 100 , the ratio of the opening size of the vent to the opening size of the air duct in the air outlet area 1632 affects the air volume of the first air outlet 1622 corresponding to the air distribution structure 900 .

[0265] In some embodiments, along the length direction of the box body 100, the opening size of the air duct of the air outlet area 1632 gradually decreases along the air flow direction.

[0266] In some embodiments, in order to adjust the air volume of the first air outlet 1622 as needed, the ventilation part 920 further includes a moving member, which is movably connected to the wind shield 910, and the moving member moves relative to the wind shield 910 to cover at least part of the vent or open the vent. Exemplarily, the moving member can be rotatably connected to the wind shield 910, or slidably connected.

[0267] It is understandable that, in some embodiments, the housing 100 is constructed with at least two first air outlets 1622 arranged at intervals. At least two hydroponic components 200 are arranged in the second chamber 120, and at least two first air outlets 1622 are arranged in a one-to-one correspondence with at least two hydroponic components 200. The varieties of fruits and vegetables cultivated in each hydroponic component 200 are different, or the fruits and vegetables of the same variety in different growth periods are cultivated in each hydroponic component 200. That is to say, in some cases, the requirements of heat, humidity or carbon dioxide for fruits and vegetables in each hydroponic component 200 are different. Therefore, a wind distribution structure 900 can be set in the air outlet area 1632, and the wind distribution structure 900 is configured to change the air outlet volume of the first air outlet 1622. In this way, the wind distribution structure 900 is arranged in the air outlet area 1632, which can effectively avoid the influence of the air outlet volume of the first air outlet 1622 due to the obstruction of fruits and vegetables, and the accuracy of air outlet volume control.

[0268] In some embodiments, to improve the regulation efficiency and effect of the air in the second chamber 120, the blower 600 is located in the first region 111 and opposite to the second air return opening 1611, and the second air outlet 1612 is located below the temperature regulating device.

[0269] In some embodiments, an arc-shaped guiding portion 1613 is provided at the bottom of the second air outlet 1612. The arc-shaped guiding portion is used to guide the air to flow obliquely upward to enter the air outlet area 1632. Wherein, the projection length of the arc-shaped guiding portion in the vertical direction shall not be less than the projection length of the second air outlet 1612 in the vertical direction. In this way, the direction of the air flow can be efficiently guided, and the air supply efficiency can be improved.

[0283] In some embodiments, in order to effectively prevent the cold of the evaporator 410 or the heat of the heating element from easily passing directly through the box body into the second chamber 120, causing local overcooling or overheating in the second chamber 120, the box body 100 is further configured with a third chamber 163, and the third chamber 163 is located between the first chamber 110 and the second chamber 120.

[0284] The third chamber 163 includes a return air area 1631 and an air outlet area 1632 that are separated from each other.

The air in the second chamber 120 flows to the outside through the return air area 1631, the first area 111, and the air outlet in sequence.

[0287] In some embodiments, the box body is configured with a first return air opening 1621 and at least two first air outlet openings 1622 that are spaced apart along the length direction of the box body 100. The first return air opening 1621 is located on one side of the at least two first air outlet openings 1622 along the length direction of the box body 100. The first return air opening 1621 communicates the second chamber 120 and the return air area 1631. The first air outlet openings 1622 communicate the second chamber 120 and the air outlet area 1632. The box body 100 is configured with a second return air opening 1611 and a second air outlet opening 1612. The second return air opening 1611 communicates the first chamber 110 and the return air area 1631. The second air outlet opening 1612 communicates the first chamber 110 and the air outlet area 1632. The second air outlet opening 1612 is located on the side of the at least two first air outlet openings 1622 along the length direction of the box body 100 that is away from the first return air opening 1621. It can be understood that by providing the third chamber 163, the uniformity of the distribution of the first air outlet openings 1622 can be improved.

[0288] In some embodiments, in order to reduce the impact on the appearance, the air inlet 170 and the air outlet 180 are located on the back surface of the box body 100.

[0295] A third air damper structure 1110 is located in the first chamber 110, and the third air damper structure 1110 is configured to control the communication or non-communication between the first area 111 and the second area 112.

[0296] In some embodiments, the cabinet 100 includes a housing 130, a compressor chamber 140, an inner container 150, and an air duct assembly 160.

[0297] In some embodiments, the cabinet 100 further includes a decorative panel, which is disposed on the side of the air duct assembly 160 facing the door body and on the two inner wall sides of the inner container 150 along the width direction. Exemplarily, the decorative panel can be a brushed anodized aluminum alloy plate to improve the overall aesthetics.

[0298] In some embodiments, the housing 130 is configured with a first accommodating cavity having a first access opening and a second access opening, and the first access opening and the second access opening are respectively disposed on opposite sides of the housing 130 in the depth direction (the direction indicated by the Y-axis) of the cabinet 100. The first access opening can be disposed on the front side of the housing 130, and the second access opening can be disposed on the rear side of the housing 130. Among them, when the user is using it normally, the side closer to the user is the front side.

The opening of the compressor chamber 140 is opposite to the second access opening, and the compressor 420, the condenser, etc. can be placed into the compressor chamber 140 through the second access opening and the opening. The inner container 150 is located inside the housing 130. The inner container 150 has a third access opening, and the third access opening is opposite to the first access opening.

A foaming layer is filled between the inner container 150, the housing 130, and the compressor chamber 140, and the foaming layer is used for heat insulation and heat preservation.

[0300] Exemplarily, the housing 130 can include a first bottom plate, a first top plate, first side plates, and a first rear plate. The first bottom plate and the first top plate are oppositely disposed in the length direction (the direction indicated by the Z-axis) of the cabinet 100. There are two first side plates.

[0305] Figure 24 Another schematic structural diagram of the air duct assembly in the fruit and vegetable cultivation device provided by the embodiment of the present application Figure 25 is Figure 24 a cross-sectional view of Figure 26 is Figure 25 a partial enlarged view at C in

[0306] Referring to Figures 24 to 26 As shown, in some embodiments, the air duct assembly 160 includes a first partition member 161 and a second partition member 162 connected to each other. The first partition member 161 is connected to the inner wall of the box liner 150 in the depth direction, and the space between the first partition member 161 and the inner wall of the box liner 150 in the depth direction is the first chamber 110. The second partition member 162 is disposed on the side of the first partition member 161 facing the door body 300, that is, the front side of the second partition member 162, and the space between the second partition member 162 and the first partition member 161 is the third chamber 163. The space between the front side of the second partition member 162 and the door body 300 is the second chamber 120. In this way, the space occupied by the air duct assembly 160, the blower 600, the evaporator 410, and the heating element is relatively small.

[0307] The second partition member 162 is provided with a first air return opening 1621 and a first air outlet 1622. The first air return opening 1621 is communicated with the second chamber 120 and is also communicated with the air return area 1631. The first air outlet 1622 is communicated with the second chamber 120 and is also communicated with the air outlet area 1632. Exemplarily, the number of the first air outlets 1622 may be one, two, or more, and the multiple first air outlets 1622 are arranged at intervals. For example, three or four, which are not elaborated in this embodiment.

[0308] A second air return opening 1611 and a second air outlet 1612 are provided on the first partition member 161. The second air return opening 1611 communicates with the first chamber 110 and also communicates with the air return area 1631. The second air outlet 1612 communicates with the first chamber 110 and also communicates with the air outlet area 1632. The blower 600 is disposed opposite to the second air return opening 1611.

[0309] In some embodiments, the material of the inner container 150 may be engineering plastic ABS board or PS.

[0310] In some embodiments, the refrigeration system 400 may include a compressor 420, a condenser, a throttling device, and an evaporator 410. The compressor 420, the condenser, the throttling device, and the evaporator 410 are sequentially connected in series through pipelines, and a refrigerant flows through the pipelines. The compressor 420 and the condenser may be disposed in the compressor compartment 140.

[0311] When it is necessary to cool the second chamber 120, when the compressor 420 operates, the low-temperature and low-pressure refrigerant is sucked into the compressor 420, compressed into a high-temperature and high-pressure superheated gas in the cylinder of the compressor 420, and then discharged into the condenser. The high-temperature and high-pressure refrigerant gas dissipates heat through the condenser, and its temperature continuously drops, gradually being cooled into a normal-temperature and high-pressure saturated vapor, and further cooled into a saturated liquid. The pressure of the refrigerant remains almost unchanged during the entire condensation process. The throttling device may include a decompression tube or an electronic expansion valve. In this application, the throttling device including a decompression tube is taken as an example for description. The decompression tube has a low cost and is not prone to abnormal failures. The condensed refrigerant saturated liquid is throttled and depressurized through the decompression tube, and the refrigerant becomes a normal-temperature and low-pressure wet vapor. Then, the normal-temperature and low-pressure wet vapor absorbs heat and vaporizes through the evaporator 410, not only reducing the temperature of the evaporator 410 and its surrounding area, but also turning the refrigerant into a low-temperature and low-pressure gas. The evaporator 410 cools the air in the first chamber 110, so that the temperature of the air in the first chamber 110 decreases. Under the action of the blower 600, the cold air in the first chamber 110 flows into the second chamber 120 through the air duct assembly 160, so that the temperature of the second chamber 120 decreases. The refrigerant coming out of the evaporator 410 returns to the compressor 420 again, repeating the above process, so that the evaporator 410 can continuously cool the air in the first chamber 110, and further enable the second chamber 120 to be maintained at a set temperature. It can be understood that by using the air-cooling method to cool the second chamber 120, the temperature in the second chamber 120 is more uniform.

[0312] In some embodiments, the refrigeration system 400 may further include a dryer filter, which is connected between the condenser and the throttling device through a pipeline, and the dryer filter can filter out moisture and impurities in the refrigerant.

[0313] In some embodiments, the fruit and vegetable cultivation device further includes a controller and a second temperature sensor. The second temperature sensor, the refrigeration system 400, and the heating element are all electrically connected to the controller. The second temperature sensor is used to detect the temperature inside the second chamber 120, and the controller is used to control the turning on or off of the refrigeration system 400 and the heating element according to the temperature. Exemplarily, when the temperature is greater than the maximum value of the preset range, the controller controls the refrigeration system 400 to turn on. When the refrigeration system 400 operates to cool the inside of the second chamber 120 to within the preset range, the controller controls the refrigeration system 400 to turn off. When the temperature is less than the minimum value of the preset range, the controller controls the heating element to turn on. When the heating element operates to heat the inside of the second chamber 120 to within the preset range, the controller controls the heating element to turn off.

[0314] It can be understood that, for the growth of fruits and vegetables, it is also necessary to ensure the carbon dioxide content in the second chamber 120 to ensure that the fruits and vegetables can carry out photosynthesis. An air inlet 170 and an air outlet 180 communicating with the outside of the fruit and vegetable cultivation device are provided on the box body 100. Both the air outlet 180 and the air inlet 170 communicate with the first chamber 110. The fan 600 is configured to convey the air outside the fruit and vegetable cultivation device into the second chamber 120 successively through the air inlet 170 and the first chamber 110, and convey the air inside the second chamber 120 to the outside of the fruit and vegetable cultivation device successively through the first chamber 110 and the air outlet 180.

[0315] Specifically, the air inlet 170 is close to the second air outlet 1612, and a first air damper structure 190 is provided at the position between the air inlet 170 and the second air outlet 1612. The first air damper structure 190 is used to connect or disconnect the air inlet 170 from the first chamber 110. The air outlet 180 is close to the second air return port 1611, and a second air damper structure 1100 is provided at the position between the air outlet 180 and the second air return port 1611. The second air damper structure 1100 is used to connect or disconnect the air outlet 180 from the first chamber 110. A third air damper structure 1110 is provided inside the first chamber 110. The third air damper structure 1110 is located between the second air outlet 1612 and the second air return port 1611. The third air damper structure 1110 is used to connect or disconnect the second air outlet 1612 and the second air return port 1611.

[0316] When the fruit and vegetable cultivation equipment needs to adjust the carbon dioxide content in the second chamber 120, the fruit and vegetable cultivation equipment will perform external air circulation. Through the external circulation, the carbon dioxide content in the second chamber 120 can be supplemented. During operation, the first air door structure 190 is opened to connect the air inlet 170 with the first chamber 110. The second air door structure 1100 is opened to connect the air outlet 180 with the first chamber 110. The third air door structure 1110 is closed, so that the second air outlet 1612 and the second air return port 1611 are not connected. Under the action of the fan 600, the outside air enters the first chamber 110 through the air inlet 170, moves downward along the first chamber 110, is cooled by the evaporator 410 or heated by the heating element or the evaporator 410 and the heating element do not work, and then enters the air outlet area 1632 through the second air outlet 1612 and enters the second chamber 120 through the first air outlet 1622. The air in the second chamber 120 enters the air return area 1631 through the first air return port 1621, then enters the first chamber 110 through the second air return port 1611, and flows to the outside of the fruit and vegetable cultivation equipment through the air outlet 180.

[0317] When it is not necessary to adjust the carbon dioxide content in the second chamber 120, that is to say, when the fruit and vegetable cultivation equipment needs to perform internal circulation, the first air door structure 190 is closed to disconnect the air inlet 170 from the first chamber 110. The second air door structure 1100 is closed to disconnect the air outlet 180 from the first chamber 110. The third air door structure 1110 is opened, so that the second air outlet 1612 and the second air return port 1611 are connected. Under the action of the fan 600, the air in the second chamber 120 enters the air return area 1631 through the first air return port 1621, then enters the first chamber 110 through the second air return port 1611, moves downward along the first chamber 110, is cooled by the evaporator 410 or heated by the heating element or the evaporator 410 and the heating element do not work, and then enters the air outlet area 1632 through the second air outlet 1612 and enters the second chamber 120.

[0318] It should be noted that the first air door structure 190, the second air door structure 1100 and the third air door structure 1110 can all be electronic air door structures and are all electrically connected to the controller, so as to improve the degree of automation.

[0319] In some embodiments, the fruit and vegetable cultivation device further includes a carbon dioxide sensor electrically connected to the controller, and the carbon dioxide sensor is configured to detect the concentration of carbon dioxide in the second chamber 120. The controller is configured to control the opening or closing of the first air damper structure 190, the second air damper structure 1100, and the third air damper structure 1110 according to the concentration of carbon dioxide. That is, the controller is configured to select an external circulation mode or an internal circulation mode according to the concentration of carbon dioxide. Exemplarily, when the concentration of carbon dioxide is less than a preset value, the controller controls the first air damper structure 190 to open, the second air damper structure 1100 to open, and the third air damper structure 1110 to close. When the concentration of carbon dioxide is greater than or equal to the preset value, the controller controls the first air damper structure 190 to close, the second air damper structure 1100 to close, and the third air damper structure 1110 to open.

[0320] In some embodiments, a first temperature sensor is further included, and the first temperature sensor, the refrigeration system, and the heating element are all electrically connected to the controller.

[0321] The first temperature sensor is configured to detect the temperature outside the fruit and vegetable cultivation device, and the controller is configured to control the opening or closing of the heating element and the refrigeration system according to the temperature. Specifically, when the fruit and vegetable cultivation device needs to perform external circulation, the first temperature sensor is configured to detect the temperature outside the fruit and vegetable cultivation device. When the detected temperature outside the fruit and vegetable cultivation device is lower than the temperature in the second chamber 120, the controller controls the heating element to turn on. When the detected temperature outside the fruit and vegetable cultivation device is higher than the temperature in the second chamber 120, the controller controls the refrigeration system to turn on, thereby facilitating the maintenance of the temperature in the second chamber 120.

[0322] In this way, when the external circulation is turned on, it is convenient to keep the temperature in the second chamber 120 stable.

[0323] In this embodiment, the fruit and vegetable cultivation device is provided with a first humidity sensor and a second humidity sensor. The first humidity sensor and the second humidity sensor are both electrically connected to the controller. The first humidity sensor is configured to detect the first humidity in the second chamber 120. The second humidity sensor is configured to detect the second humidity outside the fruit and vegetable cultivation device.

[0324] When the first humidity is greater than the preset humidity range, the controller compares the second humidity value with the preset humidity range. If the second humidity is less than or within the preset humidity range, the controller controls the fruit and vegetable cultivation device to turn on the external circulation mode. If the second humidity is greater than the preset humidity range, the controller controls the refrigeration system to start working.

[0325] When the first humidity is less than the preset humidity range, the controller compares the second humidity value with the preset humidity range. If the second humidity is greater than or within the preset humidity range, the controller controls the fruit and vegetable cultivation device to turn on the external circulation mode. If the second humidity is less than the preset humidity range, the controller controls the heating element to start working.

[0326] It can be understood that in this way, the humidity in the second chamber 120 can be kept relatively constant and the energy consumption is relatively low.

[0327] In some embodiments, the fruit and vegetable cultivation device is provided with a first carbon dioxide sensor and a second carbon dioxide sensor. Both the first carbon dioxide sensor and the second carbon dioxide sensor are electrically connected to the controller. The first carbon dioxide sensor is used to detect the first carbon dioxide concentration in the second chamber 120. The second carbon dioxide sensor is used to detect the second carbon dioxide concentration outside the fruit and vegetable cultivation device.

[0328] When the first carbon dioxide concentration is greater than the preset carbon dioxide concentration range, the controller controls the fruit and vegetable cultivation device to turn on the external circulation mode.

[0329] When the first carbon dioxide concentration is less than the preset carbon dioxide concentration range, the controller compares the second carbon dioxide concentration value with the preset carbon dioxide concentration range. If the second carbon dioxide concentration is greater than or within the preset carbon dioxide concentration range, the controller controls the fruit and vegetable cultivation device to turn on the external circulation mode. If the second carbon dioxide concentration is less than the preset carbon dioxide concentration range, the controller controls the carbon dioxide generating device to start working.

[0330] It can be understood that in this way, the carbon dioxide concentration in the second chamber 120 can be kept relatively constant and the energy consumption is relatively low.

[0331] In some embodiments, the fruit and vegetable cultivation device is provided with a first temperature sensor and a second temperature sensor. Both the first temperature sensor and the second temperature sensor are electrically connected to the controller. The second temperature sensor is used to detect the first temperature in the second chamber 120. The first temperature sensor is used to detect the second temperature outside the fruit and vegetable cultivation device.

[0332] When the first temperature is greater than the preset temperature range, the controller compares the second temperature value with the preset temperature range. If the second temperature is less than or within the preset temperature range, the controller controls the fruit and vegetable cultivation device to turn on the external circulation mode. If the second temperature is greater than the preset temperature range, the controller controls the refrigeration system to start working.

[0333] When the first temperature is less than the preset temperature range, the controller compares the second temperature value with the preset temperature range. If the second temperature is greater than or within the preset temperature range, the controller controls the fruit and vegetable cultivation device to turn on the external circulation mode. If the second temperature is less than the preset temperature range, the controller controls the heating element to start working.

[0334] It can be understood that in this way, the temperature in the second chamber 120 can be ensured to be relatively constant and the energy consumption is relatively low.

[0335] On the other hand, an embodiment of the present application provides a control method for a fruit and vegetable cultivation device, which is used for the above-mentioned fruit and vegetable cultivation device. The method includes:

[0336] Obtain the first humidity value in the second chamber of the fruit and vegetable cultivation device;

[0337] Obtain the second humidity value outside the fruit and vegetable cultivation device;

[0338] Compare the first humidity value with the preset humidity range;

[0339] If the first humidity value is greater than the maximum value of the preset humidity range, then compare the second humidity value with the preset humidity range; if the second humidity value is not greater than the maximum value of the preset humidity range, then control the fruit and vegetable cultivation device to turn on the external circulation mode. If the second humidity value is greater than the maximum value of the preset humidity range, then control the refrigeration system to turn on;

[0340] If the first humidity value is less than the minimum value of the preset humidity range, then compare the second humidity value with the preset humidity range; if the second humidity value is not less than the minimum value of the preset humidity range, then control the fruit and vegetable cultivation device to turn on the external circulation mode. If the second humidity value is less than the minimum value of the preset humidity range, then control the heating element to turn on.

[0341] It should be noted that if the first humidity value is within the preset humidity range, no adjustment is required. The preset humidity range can be a range interval or only a specific value. In the initial state, the fruit and vegetable cultivation device is in the internal circulation mode.

[0342] Specifically, the fruit and vegetable cultivation device is provided with a first humidity sensor and a second humidity sensor. Both the first humidity sensor and the second humidity sensor are electrically connected to the controller. The first humidity sensor is used to detect the first humidity in the second chamber 120. The second humidity sensor is used to detect the second humidity outside the fruit and vegetable cultivation device.

[0343] When the first humidity is greater than the preset humidity value, the controller compares the second humidity value with the preset humidity range. If the second humidity is less than or equal to the preset humidity value, the controller controls the fruit and vegetable cultivation device to turn on the external circulation mode. If the second humidity is greater than the preset humidity value, the controller controls the refrigeration system to start working.

[0344] When the first humidity is less than the preset humidity value, the controller compares the second humidity value with the preset humidity value. If the second humidity is greater than or equal to the preset humidity value, the controller controls the fruit and vegetable cultivation device to turn on the external circulation mode. If the second humidity is less than the preset humidity value, the controller controls the heating element to start working.

[0345] It can be understood that by using the above method to regulate the humidity, the energy consumption is relatively small.

[0346] An embodiment of the present application provides a control method for a fruit and vegetable cultivation device, which is used for the above-mentioned fruit and vegetable cultivation device. The method includes:

[0347] Obtain the temperature value of the second chamber of the fruit and vegetable cultivation device;

[0348] Compare the temperature value with the preset temperature range;

[0349] If the temperature value is greater than the maximum value of the preset temperature range, turn on the refrigeration system of the fruit and vegetable cultivation device;

[0350] If the temperature value is less than the minimum value of the preset temperature range, turn on the heating element of the fruit and vegetable cultivation device;

[0351] If the temperature value belongs to the preset temperature range, turn off the refrigeration system and the heating element.

[0352] It should be noted that the preset temperature range can be a range interval or only a specific value.

[0353] In this way, under the action of the fan 600, the refrigeration system generates cold or the heating element generates heat and is transmitted into the second chamber 120 to adjust the temperature of the second chamber 120, thereby providing a suitable temperature environment for the fruits and vegetables, meeting the growth requirements of different fruits and vegetables, and increasing the variety selection of fruits and vegetables that can be planted.

[0354] An embodiment of the present application provides a control method for a fruit and vegetable cultivation device, which is used for the above-mentioned fruit and vegetable cultivation device. The method includes:

[0355] Obtain the concentration value of carbon dioxide in the second chamber of the fruit and vegetable cultivation device;

[0356] Compare the concentration value with the preset concentration range;

[0357] If the concentration value is less than the minimum value of the preset concentration range, turn on the external circulation mode of the fruit and vegetable cultivation device;

[0358] If the concentration value is greater than or belongs to the preset concentration range, turn on the internal circulation mode of the fruit and vegetable cultivation device.

[0359] It should be noted that the preset concentration range can be a range interval or only a specific value.

[0360] It can be understood that in this way, the concentration of carbon dioxide in the second chamber 120 can be regulated to meet the requirements of fruit and vegetable growth.

[0361] In a possible implementation manner, if the concentration value is less than the minimum value of the preset concentration range, the external circulation mode of the fruit and vegetable cultivation device is turned on, including:

[0362] Open the first air door structure, open the second air door structure, and close the third air door structure.

[0363] In a possible implementation manner, if the concentration value is greater than or within the preset concentration range, the internal circulation mode of the fruit and vegetable cultivation device is turned on, including:

[0364] Close the first air door structure, close the second air door structure, and open the third air door structure.

[0365] In some embodiments, before turning on the external circulation mode of the fruit and vegetable cultivation device, it further includes

[0366] Obtain the first temperature value outside the fruit and vegetable cultivation device;

[0367] Obtain the second temperature value of the second chamber of the fruit and vegetable cultivation device;

[0368] Compare the first temperature value and the second temperature value;

[0369] If the first temperature value is less than the second temperature value, turn on the heating element;

[0370] If the first temperature value is greater than the second temperature value, turn on the refrigeration system.

[0371] In this way, when the external circulation is turned on, it is convenient to keep the temperature in the second chamber 120 stable.

[0372] [Liquid supply system]

[0373] Figure 27 It is a schematic structural diagram of the liquid supply system and the hydroponic component in the fruit and vegetable cultivation device provided by the embodiment of the present application.

[0374] See Figure 27 As shown, in some embodiments, the liquid supply system 700 is connected to the hydroponic component 200 to continuously supply nutrient solution to the hydroponic component 200.

[0375] The liquid supply system 700 includes a water tank 710 and a water pump 720. The water tank 710 is located inside the box body 100. The water pump 720 is connected to the box body 100. The water tank 710 is connected to the hydroponic component 200. The nutrient solution in the water tank 710 is transported to the hydroponic component 200 by the water pump 720, and then flows to the water tank 710 through the hydroponic component 200.

[0376] In some embodiments, the water pump 720 may be disposed in the water tank 710. Alternatively, the water pump 720 may be disposed on the back of the water tank 710.

[0377] In some embodiments, the water tank 710 may be located at the bottom of the hydroponic component 200 and on the front side of the press compartment.

[0378] In some embodiments, the number of the hydroponic components 200 is at least two, and the at least two hydroponic components 200 are spaced along the length direction of the box body 100. The water inlet of the uppermost hydroponic component 200 is communicated with the water tank 710 through a pipeline, and the water outlet is communicated with the water inlet of the second-layer hydroponic component 200 through a pipeline, and so on. The water outlet of the lowermost hydroponic component 200 is communicated with the water tank 710 through a pipeline. Under the action of the water pump 720, the nutrient solution in the water tank 710 enters through the water inlet in the uppermost hydroponic component 200. When the water level reaches a preset height, the nutrient solution enters the next-layer hydroponic component 200 through the water outlet and the pipeline in the uppermost hydroponic component 200, and so on. In this way, the gravity of the nutrient solution can be utilized for transportation, reducing the energy consumption of the water pump 720.

[0379] In some embodiments, the number of the hydroponic components 200 is at least two, and the at least two hydroponic components 200 are spaced along the length direction of the box body 100. The water inlets of the hydroponic components 200 at each layer are communicated with the water tank 710 through pipelines, and the water outlets are communicated with the water tank 710 through pipelines. That is to say, the hydroponic components 200 at each layer are independently supplied with liquid and returned, which is safer and more reliable and reduces the leakage of the nutrient solution.

[0380] Figure 28 It is a schematic structural diagram of a water tank in the fruit and vegetable cultivation device provided by the embodiment of the present application.

[0381] See Figure 28 As shown, in some embodiments, a pipeline fixing structure 714 is provided on the inner bottom wall of the water tank 710. The pipeline fixing structure 714 includes a supporting part and a connecting part that are connected to each other. The number of the supporting parts may be at least two, and the at least two supporting parts are spaced along the circumferential direction of the connecting part. The supporting part is connected to the inner bottom wall of the water tank 710, and there is a gap between the connecting part and the inner bottom wall of the water tank 710. The pipeline is connected to the connecting part and is communicated with the hollow flow channel of the connecting part. It can be understood that the nutrient solution of the hydroponic component enters the water tank 710 through the pipeline and the connecting part and is close to the bottom of the water tank 710, which is beneficial to preventing liquid splashing and has less noise. The nutrient solution in the water tank 710 enters the hydroponic component through the connecting part and the pipeline, which is beneficial to sucking the liquid near the bottom of the water tank 710, thereby reducing the lowest liquid level value of the water tank 710. Moreover, it is beneficial to reduce the air in the pipeline and reduce the noise.

[0382] Exemplarily, the connecting portion may be in a shape matching the pipeline, such as a cylindrical shape. The pipeline may be inserted into the connecting portion.

[0383] Figure 29 It is a schematic structural diagram of another angle of the water tank in the fruit and vegetable cultivation device provided by the embodiment of the present application.

[0384] See Figure 29 As shown, in some embodiments, the box body 100 is constructed with an inner cavity having an opening. The hydroponic component 200 is located in the inner cavity through the opening. The water tank 710 is located in the inner cavity through the opening. Since the weight of the water tank 710 is relatively large, it is inconvenient for the user to take out the water tank 710 when adding liquid to the water tank 710 during the preparation of the nutrient solution.

[0385] To solve the above technical problems, in this embodiment, the water tank 710 includes a water tank body 711 and a diversion member 712. The water tank body 711 is constructed with a liquid storage cavity. The diversion member 712 is constructed with a flow channel. The diversion member 712 is movably connected to the side of the water tank body 711 facing the opening. The flow channel of the diversion member 712 is communicated with the liquid storage cavity. The diversion member 712 moves towards the opening so that the water inlet of the flow channel of the diversion member 712 is located outside the water tank body 711. In this way, when adding liquid to the water tank 710, only need to move the diversion member 712 towards the opening to expose the water inlet of the diversion member 712 outside the water tank body 711. The user adds the liquid into the diversion member 712 from the water inlet of the diversion member 712, and the liquid enters the liquid storage cavity of the water tank body 711 along the flow channel of the diversion member 712.

[0386] In some embodiments, the diversion member 712 is rotatably connected to the side of the water tank body 711 facing the opening. In the initial state, the diversion member 712 is embedded in the side of the water tank body 711 facing the opening, and the water tank body 711 closes the water inlet of the flow channel of the diversion member 712. The diversion member 712 moves towards the opening so that the water inlet of the flow channel of the diversion member 712 is located outside the water tank body 711.

[0387] It can be understood that in the initial state, the diversion member 712 is embedded in the side of the water tank body 711 facing the opening, which is beneficial to improving the overall aesthetics, and the diversion member 712 is not likely to hinder the opening and closing of the door body. Moreover, compared with the sliding connection between the diversion member 712 and the side of the water tank body 711 facing the opening, the force required for the user to rotate the diversion member 712 is less than the force required for sliding the diversion member 712. Therefore, it is convenient for the user to operate and improves the user experience.

[0388] Figure 30 It is a schematic structural diagram of the water tank body in the fruit and vegetable cultivation device provided by the embodiment of the present application.

[0389] See Figure 30As shown, in some embodiments, an installation cavity is formed on one side of the water tank body 711 facing the opening, and the installation cavity is matched with the flow guide member 712. At least two rotating shafts 7111 are provided on the side wall of the installation cavity, and the at least two rotating shafts 7111 are arranged oppositely. At least two rotating shaft cavities 7121 are provided on the side wall of the flow guide member 712, and the at least two rotating shaft cavities 7121 are arranged in one-to-one correspondence with the at least two rotating shafts 7111. The rotating shaft 7111 is inserted into the rotating shaft cavity 7121. In this way, the connection structure between the flow guide member 712 and the water tank body 711 is relatively simple, the installation efficiency is high, and the cost is low.

[0390] In some embodiments, in order to effectively prevent the flow guide member 712 from automatically opening and affecting the appearance effect, at least two limiting protrusions 7112 are provided on the side wall of the installation cavity, and the at least two limiting protrusions 7112 are arranged oppositely. At least two limiting cavities 7122 are provided on the side wall of the flow guide member 712, and the at least two limiting cavities 7122 are arranged in one-to-one correspondence with the at least two limiting protrusions 7112. In the initial state, the limiting protrusion 7112 is inserted into the limiting cavity 7122.

[0391] See Figure 31 As shown, in some embodiments, in order to effectively prevent liquid leakage during the liquid adding process, the flow guide member 712 includes a flow guiding portion 7123 and a connecting portion 7124 that are connected to each other, and the connecting portion 7124 is rotatably connected to the water tank body 711. The flow guiding portion 7123 is provided with a flow channel. From the end far away from the connecting portion 7124 to the end close to the connecting portion 7124, the size of the flow channel of the flow guiding portion 7123 gradually decreases, and the bottom of the flow channel of the flow guiding portion 7123 is communicated with the liquid storage cavity.

[0392] In some embodiments, in order to facilitate user operation, the flow guide member 712 further includes an operation portion 7125, and the operation portion 7125 is arranged on the side of the connecting portion 7124 facing away from the flow guiding portion 7123. Press the operation portion 7125, and the operation portion 7125 rotates away from the opening, so that the flow guiding portion 7123 rotates towards the opening.

[0393] It can be understood that when the user needs to add liquid, press the operation portion 7125, the operation portion 7125 rotates away from the opening, and the flow guiding portion 7123 rotates towards the opening, so that the water inlet of the flow channel of the flow guiding portion 7123 is located outside the water tank body 711. The user adds the liquid from the water inlet of the flow guide member 712 into the flow guide member 712, and the liquid enters the liquid storage cavity of the water tank body 711 along the flow channel of the flow guide member 712.

[0394] After the liquid adding is completed, press the flow guiding portion 7123, the flow guiding portion 7123 rotates away from the opening, and the operation portion 7125 rotates towards the opening until the limiting protrusion is inserted into the limiting cavity. At this time, the flow guide member 712 is embedded on the side of the water tank body 711 facing the opening.

[0395] In some embodiments, a connecting structure 7113 is provided at a position near the bottom of the installation cavity, and the connecting structure 7113 communicates with a position near the bottom of the liquid storage cavity. The bottom of the flow channel is communicated with the connecting structure 7113 through a pipeline. In this way, it is beneficial for the added liquid to flow below the liquid level of the liquid storage cavity, thereby facilitating the prevention of liquid splashing and reducing noise.

[0396] In some embodiments, for aesthetic and pipeline protection purposes, the pipeline is located within the area enclosed by the connecting portion 7124, the operating portion 7125, and the inner wall of the installation cavity. Among them, the pipeline is a flexible hose.

[0397] In some embodiments, to facilitate the maintenance of the devices in the water tank 710 and the cleaning of the water tank 710, the water tank 710 is slidably connected to the box body.

[0398] In some implementations, a water-oxygen detector is still provided in the water tank 710. Both the water-oxygen detector and the water pump 720 are electrically connected to the controller. The water-oxygen detector is used to detect the oxygen content in the nutrient solution, and the controller controls the rotation speed of the water pump 720 according to the oxygen content.

[0399] In some embodiments, a pH sensor and a soluble ion concentration sensor are provided in the water tank 710, and both the pH sensor and the soluble ion concentration sensor are electrically connected to the controller. The pH sensor is used to detect the pH of the nutrient solution, and the soluble ion concentration sensor detects the soluble ion concentration of the nutrient solution.

[0400] It can be understood that the culture solution includes water, the original culture solution, and the acid-base solution. Through the pH sensor and the soluble ion concentration sensor, the user can be prompted to add the original culture solution and the acid-base solution.

[0401] To monitor the liquid level of the water tank 710, a liquid level sensor can be provided in the water tank 710. The liquid level sensor is electrically connected to the controller, and the liquid level sensor is used to detect the liquid level of the nutrient solution in the water tank 710.

[0402] To visually observe the liquid level of the water tank 710, the water tank 710 has an observation window 713. A transparent member is installed on the observation window 713 to display the liquid level of the nutrient solution in the water tank 710. A prompting member is provided on the water tank 710, such as a text or pattern prompt, so as to facilitate the user to control the dosage of the nutrient solution.

[0403] Specifically, the water tank 710 is provided with prompts for the highest and lowest water levels before planting. Moreover, the water tank 710 is provided with prompts for the highest and lowest water levels during the planting process.

[0404] It can be understood that, in order to protect the nutrient solution, a top cover is provided on the top of the water tank 710, and the top cover covers the top of the water tank 710.

[0405] In this embodiment, in order to ensure the root temperature required for plant growth, a second heating element is provided in the water tank 710, and the second heating element is used to heat the nutrient solution in the water tank 710.

[0406] Exemplarily, the water tank 710 includes a third temperature sensor, and the third temperature sensor is used to detect the temperature of the nutrient solution in the water tank 710.

[0407] In some embodiments, the water supply system further includes a filtering device and a sterilizing device. The filtering device is communicated with the water tank 710 and is used to filter impurities generated during the circulation of the nutrient solution.

[0408] The sterilizing device can be arranged inside the box body to sterilize the nutrient solution in the water tank 710. For example, the sterilizing device can be an ultraviolet sterilizing device, or a plasma sterilizing device, etc.

[0409] In some embodiments, a stirring device is further provided in the water tank 710, and the stirring device is connected to the controller. The water-oxygen detector is used to detect the oxygen content in the nutrient solution, and the controller controls the opening or closing of the stirring device according to the oxygen content.

[0410] [Hydroponic Component]

[0411] Figure 32 It is a schematic structural diagram of the hydroponic component in the fruit and vegetable cultivation device provided by the embodiment of the present application.

[0412] See Figure 27 and Figure 32 As shown, in some embodiments, the hydroponic component 200 is slidably connected to the side wall of the inner tank 150, so as to facilitate moving the hydroponic component 200 to the outside of the box body 100 to take care of the fruits and vegetables. Exemplarily, a slide rail is provided on the side wall of the inner tank 150, and the hydroponic component 200 is slidably connected to the slide rail through a slider.

[0413] In some embodiments, the hydroponic component 200 is arranged inside the box body 100. The water tank 710 is arranged inside the box body 100, and the water tank 710 is communicated with the hydroponic component 200 through a pipeline. In this way, when the hydroponic component 200 is pulled out of the box body 100, the pipeline moves along with the hydroponic component 200, effectively avoiding the liquid in the pipeline from dripping into the box body 100.

[0414] The hydroponic component 200 includes: a base 210 and a water tray 220. The base 210 is slidably connected to the box body 100, and the pipeline is connected to the base 210. The water tray 220 is detachably connected to the base 210. The liquid in the water tank 710 flows into the water tray 220 through the pipeline and the base 210, and the liquid in the water tray 220 flows into the water tank 710 through the base 210 and the pipeline. The water tray 220 is configured to hold fruits and vegetables.

[0415] It can be understood that when the water tray 220 needs to be cleaned and the hydroponic component 200 is pulled out of the box body 100, the pipeline moves along with the hydroponic component 200. Then, the water tray 220 is removed from the base 210 and cleaned. In this way, when removing the water tray 220, there is no need to remove the pipeline from the hydroponic component 200, thereby improving the convenience of user operation.

Figure 39 is Figure 34 the partial enlarged view at F in Figure 40 is Figure 35 the partial enlarged view at G in

[0417] See Figures 33 to 40 As shown, in some embodiments, the base 210 includes a base body 211 and a first water inlet structure 212 and a first water outlet structure 213 provided on the base body 211. The water tray 220 includes a water tray body 227 and a second water inlet structure 221 and a second water outlet structure 222 provided at the bottom of the water tray body 227. The water tray body 227 is configured with a liquid storage cavity, and both the second water inlet structure 221 and the second water outlet structure 222 are communicated with the liquid storage cavity.

[0418] In some embodiments, the water tray body 227 is slidably connected to the base body 211 along the depth direction of the box body 100. The second water inlet structure 221 abuts against or has a spacing from the first water inlet structure 212 to enable the second water inlet structure 221 to communicate with the first water inlet structure 212. The second water outlet structure 222 abuts against or has a spacing from the first water outlet structure 213 to enable the second water outlet structure 222 to communicate with the first water outlet structure 213.

[0419] In some embodiments, the water tray body 227 is inserted into the base body 211, and the second water inlet structure 221 is inserted into the first water inlet structure 212 to enable the second water inlet structure 221 to communicate with the first water inlet structure 212. The second water outlet structure 222 is inserted into the first water outlet structure 213 to enable the second water outlet structure 222 to communicate with the first water outlet structure 213.

[0420] Each hydroponic component 200 is provided with an inlet pipe and an outlet pipe for supplying and draining liquid to and from the hydroponic component 200. The inlet pipe is connected to the first inlet structure 212, and the outlet pipe is connected to the first outlet structure 213.

[0421] It can be understood that the water tray 220 and the base 210 achieve waterway connection through a plug-in method, with high efficiency in disassembly and installation, convenient operation, and good sealing performance.

[0422] In some embodiments, the base body 211 can be rectangular. The base body 211 has an inner cavity that matches the bottom of the water tray 220, so that the water tray 220 can be inserted onto the base body 211.

[0423] In some embodiments, for the convenience of user operation, a handle is provided at the bottom of the side of the base body 211 close to the door body for the user to pull.

[0424] In some embodiments, the first inlet structure 212 includes a first inlet portion 2121 and a second inlet portion 2122 that are interconnected. The first inlet portion 2121 is provided on the side wall of the base body 211, and the second inlet portion 2122 is provided on the inner bottom wall of the base body 211. The extending direction of the second inlet portion 2122 is consistent with the length direction of the box body 100.

[0425] The first inlet portion 2121 is connected to the inlet pipe. The extending direction of the second inlet structure 221 is consistent with the extending direction of the second inlet portion 2122, and the second inlet structure 221 is inserted into the second inlet portion 2122 along the length direction of the box body 100.

[0426] It can be understood that the hydroponic component 200 is pulled out of the box body 100, and then the water tray 220 is pulled upward, so that the water tray 220 is removed from the base 210. Compared with pulling out the water tray 220 along the depth direction of the box body 100, this embodiment is convenient for operation and can effectively avoid liquid splashing.

[0427] In some embodiments, the extending direction of the first inlet portion 2121 is consistent with the depth direction of the box body 100. In this way, when the hydroponic component 200 is moved along the depth direction of the box body 100, the pipeline moves on a horizontal plane, so that the pipeline can be effectively prevented from bending and affecting the flow of the liquid in the pipeline.

[0428] In some embodiments, for the convenience of pipeline layout, the first inlet structure 212 is provided on the side of the base body 211 facing away from the door body 300.

[0429] In some embodiments, the first water outlet structure 213 includes a first water outlet portion 2131 and a second water outlet portion 2132 which are interconnected. The first water outlet portion 2131 is arranged on the side wall of the base body 211, and the second water outlet portion 2132 is arranged on the inner bottom wall of the base body 211. The extension direction of the first water outlet portion 2131 is consistent with the depth direction of the box body 100, and the extension direction of the second water outlet portion 2132 is consistent with the length direction of the box body 100.

[0430] The first water outlet portion 2131 is connected to the water outlet pipe, the extension direction of the second water outlet structure 222 is consistent with the extension direction of the second water outlet portion 2132 , and the second water outlet structure 222 is inserted into the second water outlet portion 2132 along the length direction of the box body 100 .

[0431] It can be understood that when the hydroponic component 200 is pulled out of the box body 100, the pipeline moves with the hydroponic component 200, and then pulls the water tray 220 upward, so that the water tray 220 is removed from the base 210. Compared with removing the water tray 220 along the depth direction of the box body 100, this embodiment is easy to operate and can effectively avoid liquid splashing.

[0432] In some embodiments, the extension direction of the first water outlet 2131 is consistent with the depth direction of the box 100. In this way, when the hydroponic component 200 moves along the depth direction of the box 100, the pipeline moves on a fixed horizontal plane, thereby effectively avoiding bending of the pipeline and affecting the flow of liquid in the pipeline.

[0433] In some embodiments, along the length direction of the box body 100 , the second water inlet structure 221 protrudes from the inner bottom wall of the water tray 220 , and the height of the second water inlet structure 221 away from the base 210 is higher than the height of the second water outlet structure 222 away from the base 210 .

[0434] It is understandable that before the water tray 220 is disassembled, the liquid is drained through the second water outlet structure 222, and the liquid level in the water tray 220 drops to the height of the second water outlet structure 222. Since the height of the second water inlet structure 221 away from the base 210 is higher than the height of the second water outlet structure 222 away from the base 210, when the water tray 220 is disassembled, the liquid is not easy to leak from the second water inlet structure 221.

[0435] In some embodiments, a water level adjusting member 225 is further included. The water level adjusting member 225 is inserted on a side of the second water outlet structure 222 away from the base 210 and is communicated with the second water outlet structure 222 .

[0436] It is understandable that different fruits and vegetables have different requirements for the water level of the nutrient solution in the water tray 220. Therefore, the water tray 220 also includes a water level adjustment member 225. By inserting water level adjustment members 225 of different heights into the second water outlet structure 222 to adjust the height of the second water outlet structure 222, the water level of the nutrient solution can be adjusted. Exemplarily, the water level adjustment member 225 can be a water pipe.

[0437] In some embodiments, the diameter of the water level adjusting member 225 on the side facing away from the water outlet structure 222 is larger than the diameter on the side close to the water outlet structure 222 , thereby facilitating the entry of the nutrient solution.

[0438] In some embodiments, the second water outlet structure 222 protrudes from the inner bottom wall of the water tray 220. In this way, it is convenient to connect with the water level adjustment member 225. In addition, larger impurities in the liquid of the water tray 220 can sink to the inner bottom of the water tray 220 and are not easy to enter the pipeline and the water tank 710 through the second water outlet structure 222.

[0439] In some embodiments, the water tray 220 is configured with a liquid flow channel 223, and the second water inlet structure 221 and the second water outlet structure 222 are both connected to the liquid flow channel 223. The nutrient solution flows into the liquid flow channel 223 through the second water inlet structure 221, flows along the liquid flow channel 223, passes through more roots of fruits and vegetables, and finally flows out of the water tray 220 through the second water outlet structure 222.

[0440] Specifically, the water tray 220 has a water holding cavity, a second water inlet structure 221 and a second water outlet structure 222 are arranged on the bottom wall of the water holding cavity, a first partition plate is arranged between the water inlet structure 221 and the water outlet structure 222, and the heights of the water inlet structure 221 and the water outlet structure 222 are both less than the height of the first water outlet partition plate. At least one second partition plate is arranged on the bottom wall of the water holding cavity. The first partition plate, the second partition plate and the inner wall of the water holding cavity form a liquid flow channel 223. It should be noted that the setting position of the second partition plate can be set according to the demand for the liquid flow channel 223 so as to pass through more roots of fruits and vegetables, which is not specifically limited in this embodiment.

[0441] In some embodiments, for easy disassembly, an operating structure 226 is provided on the water tray 220. Specifically, the operating structure 226 can be a handle, and the water tray 220 is provided with handles on both sides along the width direction of the box 100, so that the user can remove the water tray 220 from the base 210 with both hands.

[0442] In some embodiments, a water retaining structure 224 is further provided on the water tray 220, and the water retaining structure 224 is located above the second water inlet structure 221 to effectively prevent splashing of liquid entering through the second water outlet structure 222. In the cross section perpendicular to the height direction of the box body 100, the cross-sectional area of ​​the cross section gradually increases and smoothly transitions from the direction close to the second water inlet structure 221 to the direction away from the second water inlet structure 221. In other words, the width dimension of the water retaining structure 224 gradually decreases and smoothly transitions along the height direction of the box body 100.

[0443] Figure 41 This is a schematic diagram of the structure of the folding member in the fruit and vegetable cultivation equipment provided in an embodiment of the present application.

[0444] See also Figure 41 As shown, in some embodiments, in order to prevent the pipeline from falling off during the movement of the hydroponic assembly 200 and improve the reliability of the connection between the pipeline and the hydroponic assembly 200, a folding piece 240 is also included, and the folding piece 240 is connected to the box 100 and the base 210. The water inlet pipe and the water outlet pipe are both connected to the folding piece 240.

[0445] When the hydroponic component 200 moves toward the outside of the box 100, the folding member 240, the water inlet pipe and the water outlet pipe are gradually unfolded, and when the hydroponic component 200 moves toward the inside of the box 100, the folding member 240, the water inlet pipe and the water outlet pipe are gradually folded. This is conducive to ensuring the normal operation of the pipeline and effectively avoiding air lock in the pipeline.

[0446] In some embodiments, the folding member 240 includes a first rod 241 and a second rod 242. One end of the first rod 241 is hinged to the inner wall of the box. The other end is hinged to one end of the second rod 242. The end of the second rod 242 away from the first rod 241 is hinged to the base 210. The water inlet pipe and the water outlet pipe are arranged side by side, and the water inlet pipe and the water outlet pipe are arranged in the first rod 241 and the second rod 242. In this way, the structure of the folding member 240 is simple and the space occupied is small.

[0447] In some embodiments, the lighting assembly 800 is disposed at the bottom of the base 210, and the wiring harness of the lighting assembly 800 is connected to the folding piece 240. When the hydroponic assembly 200 moves toward the outside of the box 100, the folding piece 240 and the wiring harness gradually unfold. When the hydroponic assembly 200 moves toward the inside of the box 100, the folding piece 240 and the wiring harness gradually fold.

[0448] In some embodiments, the ends of the first rod 241 and the second rod 242 are both provided with an arc portion 243 , and the radius of the arc portion 243 is not less than twice the diameter of the pipe.

[0449] It should be noted that when the diameters of the water inlet pipe and the water outlet pipe are the same, the radius of the arc portion 243 is not less than twice the diameter of the water inlet pipe. When the diameters of the water inlet pipe and the water outlet pipe are different, the radius of the arc portion 243 is not less than twice the larger diameter of the two.

[0450] It can be understood that when the radius of the arc portion 243 is less than twice the diameter of the pipe, when the pipe and the folding member are folded, the pipe is easily squeezed, thereby affecting the flow of the liquid.

[0451] In some embodiments, the radius of the arc portion 243 is not less than 1.5 times the diameter of the pipe.

[0452] In some embodiments, the radius of the arc portion 243 is not less than 3 times the diameter of the pipe.

[0453] In some embodiments, to ensure the sealing performance, at least one first sealing member is further included. At least one first installation cavity is provided on the outer wall of the second water inlet structure 221, the first sealing member is sleeved in the first installation cavity, and the first sealing member abuts against the inner wall of the second water inlet portion 2122. In this way, the first sealing member is not easily detached during the disassembly and assembly of the water tray 220, which is beneficial to ensuring the reliability of the seal. Exemplarily, the first sealing member may be a sealing ring.

[0454] In some embodiments, to ensure the sealing performance, at least one second sealing member is further included. At least one second installation cavity is provided on the outer wall of the second water outlet structure 222, the second sealing member is sleeved in the second installation cavity, and the second sealing member abuts against the inner wall of the second water outlet portion 2132. In this way, the second sealing member is not easily detached during the disassembly and assembly of the water tray 220, which is beneficial to ensuring the reliability of the seal. Exemplarily, the second sealing member may be a sealing ring.

[0455] In some embodiments, the hydroponic assembly 200 further includes a cover plate 230. The cover plate 230 covers the water tray 220, and the water tray 220 is used to hold the nutrient solution.

[0456] Among them, the cover plate 230 is provided with a plurality of planting holes, the plurality of planting holes are arranged at intervals, and the fruits and vegetables are inserted into the water tray 220 through the planting holes.

[0458] In some embodiments, to meet the light requirements of fruits and vegetables during photosynthesis, the fruit and vegetable cultivation device further includes at least one lighting assembly 800. The lighting assembly 800 is used to irradiate the hydroponic assembly 200 to provide light energy for the fruits and vegetables.

[0459] In this embodiment, the lighting assembly 800 can be provided in one-to-one correspondence with the hydroponic assembly 200, and the lighting assembly 800 is disposed above the hydroponic assembly 200. For example, the lighting assembly 800 can be disposed on the inner top wall of the box body 100, or the lighting assembly 800 can be disposed on the bottom wall of the hydroponic assembly 200 above the corresponding hydroponic assembly 200.
