Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electric sprayer technology, and in particular relates to a leak-proof connection structure for the spray bar of an electric sprayer. Background Technology
[0002] An electric sprayer is a modern agricultural tool consisting of a storage tank, filter screen, connector, suction device (small electric pump), connecting pipe, spray pipe, and nozzle connected in sequence. It is powered by a low-voltage DC power supply, which drives a low-voltage electric water pump to draw liquid out of the storage tank, and then the liquid enters the spray bar through the outlet pipe for final spraying.
[0003] Currently, electric sprayers often suffer from poor sealing at the connection between the water outlet pipe and the spray bar, and are prone to wear and tear over time. When the sprayer is in operation, the liquid can easily leak out from the connection gaps under high pressure, severely affecting the performance of the electric sprayer and the user experience. Most existing solutions involve adding a rubber gasket at the connection between the water outlet pipe and the spray bar, but the gasket is prone to corrosion and can easily be lost during disassembly and cleaning, increasing maintenance costs and resulting in low reliability. Utility Model Content
[0004] The purpose of this utility model is to address the problem that existing electric sprayers use a rubber gasket at the connection between the water outlet pipe and the spray bar, but the gasket is prone to corrosion, easily lost during disassembly and cleaning, increasing maintenance costs and resulting in low reliability. Therefore, this utility model proposes a leak-proof connection structure for the spray bar of an electric sprayer.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a leak-proof connection structure for a spray bar of an electric sprayer, comprising a handle shell and a spray bar, wherein the handle shell includes a first mounting shell and a second mounting shell, the second mounting shell being detachably connected to the first mounting shell, a water pump being provided inside the handle shell, a water outlet pipe being provided on the water pump, a connector being provided on the second mounting shell, the water outlet pipe extending into the connector, and the spray bar being connected to a reinforcing sleeve, the reinforcing sleeve being detachably connected to the connector.
[0006] As a further description of the above technical solution:
[0007] The reinforcing sleeve is provided with a water passage groove, the spray bar is connected to one end of the water passage groove, and the connector is interference-fitted to the other end of the water passage groove.
[0008] As a further description of the above technical solution:
[0009] The connector head is provided with threads, and the reinforcing sleeve is screwed onto the threads.
[0010] As a further description of the above technical solution:
[0011] The outer wall of the water passage is provided with an interference section to facilitate interference connection.
[0012] As a further description of the above technical solution:
[0013] The water outlet pipe, the water passage trough, and the spray bar are interconnected.
[0014] As a further description of the above technical solution:
[0015] A limiting shell is provided inside the second mounting housing, and the water pump is located inside the limiting shell.
[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0017] 1. In this utility model, by setting a water passage groove inside the reinforcing sleeve, when connecting the spray bar, it is only necessary to connect the spray bar to one end of the water passage groove and the other end of the water passage groove to the water outlet pipe inside the connector. This structure ensures that the water outlet pipe, water passage groove and spray bar are connected through the electric sprayer. The connector is connected to the water passage groove inside and to the reinforcing sleeve outside by thread, realizing double connection between the reinforcing sleeve and the connector. This not only improves the stability of the entire structure connection, but also improves the sealing of the internal connection, avoids wear during long-term use, and thus avoids water leakage. It makes assembly simple, maintenance costs low, and more reliable.
[0018] 2. In this utility model, a thread is provided on the connector head, and the reinforcing sleeve is screwed onto the thread. This structure converts the rotational force into an axial force, which makes the locking force of the connector head and the reinforcing sleeve large, which is beneficial for interference fit assembly.

[0032] Please see Figure 1-4 This utility model provides a technical solution: a leak-proof connection structure for the spray bar of an electric sprayer, including a handle shell 1 and a spray bar 2. The handle shell 1 includes a first mounting shell 11 and a second mounting shell 12. The second mounting shell 12 is detachably connected to the first mounting shell 11. A water pump 3 is provided inside the handle shell 1. A water outlet pipe 4 is provided on the water pump 3. A connector 5 is provided on the second mounting shell 12. The water outlet pipe 4 extends into the connector 5. The spray bar 2 is connected to a reinforcing sleeve 6. The reinforcing sleeve 6 is detachably connected to the connector 5.
[0033] The reinforcing sleeve 6 is provided with a water passage groove 7. The spray rod 2 is connected to one end of the water passage groove 7, and the connector 5 is interference-fitted to the other end of the water passage groove 7. This improves the sealing effect at the connection and prevents water leakage.
[0034] The connector 5 is provided with a thread 9, and the reinforcing sleeve 6 is screwed onto the thread 9.
[0035] The outer wall of the water passage 7 is provided with an interference section to facilitate interference connection. This allows the interference section on the outer wall of the water passage to be interference-connected with the inner wall of the connector. The interference section can be designed with an inner narrow and outer wide structure in the middle of the outer wall of the water passage, or it can be designed with a straight guide section on the outer side of the outer wall of the water passage or a straight and uniform interference fit section on the inner side of the outer wall of the water passage.
[0036] The water outlet pipe 4, the water passage trough 7, and the spray bar 2 are interconnected to ensure unobstructed internal water flow.
[0037] A limiting shell 8 is provided inside the second mounting shell 12, and the water pump 3 is located inside the limiting shell 8.
[0038] Improve the stability of water pump installation.
[0039] The structure of this utility model is not limited to setting a water passage groove inside the reinforcing sleeve and making an interference fit with the connector. Alternatively, a water passage groove can be set inside the connector, and the water passage groove inside can be made an interference fit with the inside of the reinforcing sleeve.
[0040] Working principle: By setting a water passage groove inside the reinforcing sleeve, when connecting the spray bar, simply connect the spray bar to one end of the water passage groove, and then interference-fit the other end of the water passage groove to the water outlet pipe inside the connector. This structure ensures that the water outlet pipe, water passage groove, and spray bar are connected through the inside of the electric sprayer. The connector is internally connected to the water passage groove and externally connected to the reinforcing sleeve via threads, achieving a double connection between the reinforcing sleeve and the connector. This not only improves the stability of the entire structural connection but also enhances the sealing of the internal connection, preventing wear and tear during long-term use and thus avoiding water leakage. This makes assembly simple, maintenance costs low, and more reliable.
[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
