Technical Field

[0001] This utility model relates to the field of plant irrigation technology, and in particular to an automatic watering device that integrates water and fertilizer. Background Technology

[0002] In home gardening and scientific tissue culture experiments, regular watering and fertilization are necessary to ensure healthy plant growth. Traditional watering and fertilization methods rely on manual, regular operation, which makes it difficult to guarantee the uniformity and timeliness of irrigation. At the same time, fertilization is usually carried out separately from watering, which can easily lead to fertilizer waste and uneven plant growth, affecting plant growth and development.

[0003] Most automatic watering devices on the market are single-function, only capable of watering and unable to simultaneously fertilize, thus failing to meet the synchronized water and nutrient needs of plants during growth. While some devices do offer integrated water and fertilizer functions, they are complex in structure with numerous components, resulting in high costs and demanding installation and maintenance requirements, making them unsuitable for home users or small-scale growers. Therefore, developing an automatic water and fertilizer integrated watering device that is simple in structure, low in cost, easy to operate, and capable of eliminating the need for manual watering and fertilization for a period of time is of significant practical importance. Utility Model Content

[0004] To address the problems existing in the prior art, which is that current automatic watering devices have limited functions and can only water plants, failing to meet the simultaneous water and nutrient requirements of plant growth, this invention aims to provide an integrated water and fertilizer automatic watering device. By storing water and fertilizer in the same liquid storage tank and mixing them in a mixing chamber, it achieves integrated water and fertilizer automatic watering and fertilization operations, meeting the simultaneous water and nutrient requirements of plants during their growth process and ensuring healthy plant growth.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An automatic water-fertilizer integrated irrigation device includes a storage tank, a water delivery pipe, and a drip pipe plug, as well as a fertilizer pipe and a mixing chamber. The storage tank is divided into a water storage chamber and a fertilizer chamber. The two ends of the water delivery pipe are connected to the water storage chamber and the mixing chamber, respectively. The two ends of the fertilizer pipe are connected to the fertilizer chamber and the mixing chamber, respectively. The height of the storage tank is higher than that of the mixing chamber, and the bottom of the mixing chamber is connected to the drip pipe plug.

[0007] The present invention is further configured such that the fertilizer is stored indoors as liquid fertilizer.

[0008] The present invention is further configured such that both the water pipe and the fertilizer pipe are equipped with flow control components.

[0009] The present invention is further configured to include a fertilizer box, wherein water or liquid fertilizer is stored in the fertilizer chamber, the fertilizer box has an opening and solid fertilizer is stored inside the fertilizer box, and the water or liquid fertilizer in the fertilizer chamber flows into the fertilizer pipe after passing through the fertilizer box and coming into contact with the solid fertilizer.

[0010] The present invention is further configured such that: a connector is provided at the bottom of the fertilizer box, and a fertilizer chamber for storing solid fertilizer is provided inside the fertilizer box, the connector being connected to the fertilizer chamber; a connecting pipe is provided at the top of the fertilizer tube, the connecting pipe being located at the bottom of the fertilizer chamber and connected to the fertilizer chamber, the outer diameter of the connector being equal to the inner diameter of the connecting pipe and the height of the connector being less than the length of the connecting pipe.

[0011] The present invention is further configured such that the contact surface between the fertilizer chamber and the fertilizer box, as well as the bottom surface of the fertilizer box, are all horizontally arranged.

[0012] The present invention is further configured such that: solid fertilizer particles are stored in the fertilizer chamber, and a plurality of through holes are provided on the side wall of the fertilizer box, the size of the through holes being smaller than the size of the solid fertilizer particles.

[0029] It should be noted that the embodiments and features involved in the embodiments of this utility model can be combined with each other without conflict. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0030] Example 1

[0031] As attached Figure 1 As shown, an automatic water and fertilizer integrated irrigation device includes a liquid storage tank 1, a water delivery pipe 2, a fertilizer pipe 3, a mixing chamber 5, a telescopic pipe 6, and a drip pipe plug 7.

[0032] The storage tank 1 is a rectangular box with an internal partition 14 dividing its internal space into a water chamber 11 and a fertilizer chamber 12. The top cover 13 of the storage tank 1 is openable, facilitating the addition of water or liquid fertilizer to the water chamber 11 and fertilizer chamber 12. In this embodiment, the fertilizer chamber 12 is used to store liquid fertilizer. The storage tank 1 is made of corrosion-resistant plastic material (e.g., polypropylene) and has good sealing properties to prevent internal liquid leakage.

[0033] Both the water supply pipe 2 and the fertilizer pipe 3 are made of PVC material. The two ends of the water supply pipe 2 are connected to the bottom of the water storage chamber 11 and the top of the mixing chamber 5, respectively. The two ends of the fertilizer pipe 3 are connected to the bottom of the fertilizer chamber 12 and the top of the mixing chamber 5, respectively. Each of the water supply pipe 2 and the fertilizer pipe 3 is equipped with a flow control device 4. The flow control device 4 can be a commonly available roller type or knob type, used to control the flow rate of the liquid in the water supply pipe 2 and the fertilizer pipe 3. Specifically, when the plant only needs watering, this can be achieved by completely closing the flow control device 4 on the fertilizer pipe 3.

[0034] The mixing chamber 5 is connected to both the water supply pipe 2 and the fertilizer pipe 3, and is used to mix water and fertilizer. The mixing chamber 5 is cone-shaped, with its bottom tip connected to the telescopic pipe 6. The horizontal height of the mixing chamber 5 is lower than that of the storage tank 1, allowing water or fertilizer in the storage tank 1 to flow naturally into the mixing chamber 5 under gravity and siphon effect.

[0035] The telescopic tube 6 can rotate within a certain range and change its length. The end of the telescopic tube 6 is connected to the drip pipe plug 7, which can be inserted into the soil to guide the water-fertilizer mixture in the mixing chamber 5 into the soil.

[0036] The implementation principle of the above embodiments is as follows:

[0037] When using this device, first turn off the flow control devices 4 on the water pipe 2 and fertilizer pipe 3, then open the cover 13 of the liquid storage tank 1, add water and liquid fertilizer to the water storage chamber 11 and fertilizer chamber 12 respectively, and close the cover 13. Then, turn on the flow control devices 4 on the water pipe 2 and fertilizer pipe 3 respectively, adjust the water flow and fertilizer speed, and insert the drip pipe plug 7 into the soil near the plant to achieve automatic watering and fertilization.

[0038] Example 2

[0039] As attached Figure 2-4 As shown, this utility model discloses an automatic water and fertilizer integrated irrigation device. Unlike the first embodiment, the fertilizer chamber 12 is also equipped with a fertilizer box 8 for storing block or granular solid fertilizer, and the fertilizer chamber 12 can be used to store water or liquid fertilizer.

[0040] The fertilizer box 8 is a vertically arranged cylindrical structure with a connector 81 at its bottom, and the axis of the connector 81 coincides with the axis of the fertilizer box 8.

[0041] A connecting pipe 31 is provided at the top of the fertilizer tube 3. The connecting pipe 31 is located at the bottom of the fertilizer chamber 12 and communicates with the fertilizer chamber 12. The outer diameter of the insertion pipe 81 at the bottom of the fertilizer box 8 is equal to the inner diameter of the connecting pipe 31, and the height of the insertion pipe 81 is less than the length of the connecting pipe 31, so that the insertion pipe 81 can be completely inserted into the connecting pipe 31.

[0042] In this embodiment, the contact surface between the fertilizer chamber 12 and the fertilizer box 8, as well as the bottom surface of the fertilizer box 8, are both horizontally arranged. Therefore, after the insertion pipe 81 is fully inserted into the connecting pipe 31, the bottom surface of the fertilizer box 8 is in close contact with the bottom surface of the fertilizer chamber 12, thereby preventing water or liquid fertilizer in the fertilizer chamber 12 from flowing into the fertilizer pipe 3 between the contact surface between the fertilizer box 8 and the fertilizer chamber 12.

[0043] The cavity inside the fertilizer box 8 is the fertilizer chamber 82, which is used to store block or granular solid fertilizer. The fertilizer chamber 82 is connected to the insertion pipe 81, and a filter screen 84 is horizontally installed at the bottom of the fertilizer chamber 82.

[0044] The mesh size of the filter screen 84 is smaller than the minimum size of solid fertilizer particles, thereby preventing solid fertilizer in the fertilizer chamber 82 from directly entering the insertion pipe 81. In particular, the fertilizer box 8 in this embodiment is suitable for storing solid fertilizer with larger particle size.

[0045] The fertilizer box 8 has several through holes 83 on its side wall, and the size of the through holes 83 is smaller than the size of the solid fertilizer particles, thereby preventing the solid fertilizer inside the fertilizer chamber 82 from leaking out at the through holes 83.

[0046] Water or liquid fertilizer in fertilizer chamber 12 enters fertilizer cavity 82 through through hole 83 on the side wall of fertilizer box 8, and flows into fertilizer pipe 3 after contacting solid fertilizer. During this process, solid fertilizer gradually dissolves in water or liquid fertilizer.

[0047] In this embodiment, the top and bottom of the side wall of the fertilizer box 8 are provided with through holes 83, and the number of through holes 83 at the bottom is greater than the number of through holes 83 at the top. The through holes 83 at the top can be used to expel air from the fertilizer chamber 82, while allowing a small amount of water or liquid fertilizer to enter the fertilizer chamber 82 from the top of the fertilizer box 8, preventing a large amount of water or liquid fertilizer from entering the fertilizer chamber 82 from the top of the fertilizer box 8, which would cause the solid fertilizer to dissolve too quickly; while the through holes 83 at the bottom allow more water or liquid fertilizer to enter the fertilizer chamber 82 from the bottom of the fertilizer box 8, thereby ensuring that water or liquid fertilizer still enters the fertilizer chamber 82 when the liquid level in the fertilizer chamber 12 is low, and allowing the solid fertilizer at the bottom of the fertilizer chamber 82 to move down to the bottom of the fertilizer chamber 82 by gravity after the solid fertilizer at the top of the fertilizer chamber 82 has dissolved.

[0048] In some other embodiments, the number and size of the through holes 83 can be adaptively adjusted according to the particle size and dissolution rate of the solid fertilizer used.

[0049] Example 3

[0050] As attached Figure 5 As shown, this is another fertilizer box 8 disclosed in this utility model. Unlike embodiment 2, the fertilizer cavity 82 of the fertilizer box 8 is used to store powdered solid fertilizer, and there are no holes on the side wall of the fertilizer box 8. Instead, a cylindrical dissolving channel 85 coaxial with the fertilizer box 8 is provided at the center of the fertilizer box 8.

[0051] The fertilizer chamber 82 is annular, with an opening on its side wall facing the dissolving channel 85, thus connecting the fertilizer chamber 82 and the dissolving channel 85. The bottom of the dissolving channel 85 is directly connected to the insertion pipe 81, and one or more layers of filter gauze 86 are provided between the dissolving channel 85 and the fertilizer chamber 82. When the liquid level in the fertilizer chamber 12 exceeds the height of the fertilizer box 8, the water or liquid fertilizer in the fertilizer chamber 12 enters the fertilizer chamber 82 through the dissolving channel 85, and after contacting and dissolving the powdered solid fertilizer, it penetrates the filter gauze 86 and flows into the fertilizer pipe 3. The number of layers of filter gauze 86 can be adaptively adjusted according to the dissolution rate of the powdered solid fertilizer.

[0052] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the present invention. Clearly, those skilled in the art can make various alterations and modifications to the present invention without departing from its spirit and scope. Thus, if such modifications and modifications fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include such modifications and modifications.
