Description

A split sprayer Technical Field

[0001] The present invention relates to the technical field of sprayers. Background Art

[0002] A liquid sprayer is a device used to spray liquids. It has a wide range of uses, most notably in gardening and plant protection, and can be used to spray water, fertilizer solutions, pesticides, herbicides, and more. Some sprayers include multiple, interchangeable tanks containing different liquids. The sprayer's pump and other internal components typically need to be cleaned or flushed between uses to prevent cross-contamination. Summary of the Invention

[0003] The object to be achieved by the present invention is to provide a split-type sprayer to solve the problem of cross-contamination of solutions when using water tanks containing different liquids.

[0004] In order to achieve the above-mentioned objectives, the present invention adopts the following technical solution: a split sprayer, comprising a base with a power supply, a water tank detachably connected to the base, a motor, a pump body, and a spray assembly, the pump body being installed on the water tank, the water inlet of the pump body being connected to the water tank, and the water outlet of the pump body being connected to the spray assembly, the pump body, water tank and spray assembly together forming a replaceable module; the motor is selectively combined with the replaceable module, the motor is detachably connected to the pump body, and when the water tank and the base are combined together, the motor is electrically connected to the power supply, and the motor drives the pump body to pump liquid from the water tank and spray it through the spray assembly.

[0005] After adopting the above technical solution, the present invention has the following advantages: when the motor and the replaceable module are combined, the motor, pump body, water tank and injection assembly are combined into one body and installed on the water tank. The motor is electrically connected to the power supply to drive the pump body to pump liquid from the water tank and inject it through the injection assembly. Each water tank is equipped with a separate pump body and injection assembly. When using different liquids, the replaceable module can be quickly replaced. Multiple water tanks can share a single motor, avoiding cross contamination of the solutions. There is no need to equip each water tank with a separate motor, which greatly reduces costs. At the same time, the pump body and motor are installed as a whole after being combined, and the coaxiality between the pump body and the motor is higher. Compared with the prior art method of separately installing the motor and pump body on the base and water tank, the separate installation will cause the coaxiality between the pump body and the motor to deviate. Therefore, the pumping efficiency of the motor and replaceable module combination is higher. In addition, the installation position of the motor is more flexible, the heat dissipation efficiency of the motor is higher, and the driving energy of the motor can be more effectively transferred to the pump body, thereby improving the pumping efficiency.

[0006] Furthermore, a receiving groove for the motor and pump body is provided on the outside of the water tank. Using the aforementioned technical solution, after the motor and replaceable module are assembled, the motor and pump body are installed in the receiving groove on the outside of the water tank, simplifying the assembly and disassembly process. This allows users to quickly change water tanks to use different liquids, saving costs by sharing a single motor and enabling different waterways to spray different liquids. The receiving groove secures the motor and pump body, ensuring stable operation during use, facilitating continuous liquid spraying, and facilitating quick removal and replacement of the motor, making motor installation more flexible.

[0007] Furthermore, the motor has a motor shaft, and the pump body has a pump shaft. A quick coupling structure for realizing coaxial connection is provided between the motor shaft and the pump shaft, which can realize quick connection and coaxial transmission, ensure high coaxiality between the pump body and the motor, and effectively reduce the occurrence of faults. The motor can transmit the power required for the operation of the pump body to the pump body through the quick coupling structure.

[0008] Furthermore, a quick connector is provided between the motor and the power supply. By adopting the above technical solution, the motor and the power supply can be quickly connected by using the quick connector, which is easy to operate and convenient for quickly replacing the water tank with other liquids.

[0009] Furthermore, a quick connection structure is provided between the motor and the pump body. With the above technical solution, the motor and the pump body can be quickly connected together through the quick connection structure, thereby greatly shortening the assembly time and facilitating improved spraying efficiency.

[0010] Furthermore, the base is provided with a retaining flange that mates with the bottom edge of the water tank. Using the aforementioned technical solution, the bottom edge of the water tank mates with the retaining flange of the base to retain the water tank on the base, ensuring its stability and preventing it from shifting or shaking and affecting liquid spraying. The retaining flange also provides a guide for quick and easy installation of the water tank.

[0011] Alternatively, the base is provided with a second clip for fixing the water tank. The above technical solution is adopted to further ensure the stability of the water tank and firmly and stably fix the water tank on the base.

[0012] Furthermore, the base is equipped with rollers at the bottom, and an upwardly extending front bracket is provided on the front side of the base. A handle slot is provided on the upper portion of the front bracket. With this technical solution, when the water tank is large, the liquid sprayer is heavier overall. The rollers at the bottom of the base allow the user to easily and effortlessly push and pull the base to adjust the position of the liquid sprayer, facilitating movement and improving the user experience. The handle slot facilitates the user's grip and push and pull of the liquid sprayer, making operation more convenient, comfortable, and labor-saving.

[0013] Furthermore, a shoulder strap is provided on the front bracket. The above technical solution makes it easy for the user to carry and wear the sprayer during operation, and the user can operate the spray assembly with both hands to apply the liquid to the target area.

[0014] Furthermore, the front bracket is provided with a retaining groove, and the water tank is provided with a retaining protrusion that cooperates with the retaining groove. Using the aforementioned technical solution, the water tank is provided with a retaining protrusion that cooperates with the retaining groove. The retaining groove and retaining protrusion cooperate with each other to further ensure that the water tank is stably mounted on the base, preventing the water tank from shaking or shifting.

[0015] The present invention also provides a split-type sprayer, comprising a base with a power supply and a motor, a water tank detachably connected to the base, a pump body, and a water system, wherein the water system comprises a water suction component and an injection component, the water inlet of the pump body is connected to the water tank through the water suction component, and the water outlet of the pump body is connected to the injection component, the pump body and the water system are combined into a detachable module, the detachable module is detachably mounted on the base, the motor is selectively combined with the detachable module, and the motor is detachably connected to the pump body, and when the water tank and the base are combined together, the motor drives the pump body to pump liquid from the water tank and spray it through the injection component.

[0016] When the motor is combined with the detachable module, the motor is located in the base, and the motor, pump body, and water system are installed in the base. When changing the water tank for different liquids, the corresponding pump body and water system are replaced accordingly to avoid cross-contamination of liquids. Different water systems can be sprayed with different liquids by sharing the same motor. When using water tanks with different liquids, motors of different powers can also be used to meet different usage needs, which is more flexible and convenient.

[0017] Furthermore, the base includes a mounting cavity for the motor and pump body. By providing a mounting cavity within the base, the aforementioned technical solution allows for better utilization of internal space, allowing the motor and pump body to be compactly positioned together. This facilitates removal and replacement of the motor and pump body. The mounting cavity helps protect the motor and provides a stable support for the motor and pump body, helping to reduce vibration and noise during use, providing a better user experience. It also promotes heat dissipation from the motor, improving its stability and service life, and enhancing pumping efficiency.

[0018] Furthermore, the water tank is equipped with a one-way valve, comprising a valve port, a push rod for opening and closing the valve port, and a spring that elastically presses against the push rod to close the valve port. The base is provided with a protrusion that lifts the push rod to open the valve port. Using this technical solution, when the water tank and base are assembled, the protrusion lifts the push rod, compressing the spring and opening the valve port. Liquid within the water tank can flow through the one-way valve to the pump body for spraying. When the water tank leaves the base, the protrusion lifts off the push rod, causing the spring to extend and reset the push rod, closing the valve port. This means that the valve port automatically closes after the water tank leaves the base, ensuring that liquid does not overflow from the tank. The water tank may also be provided with a drain port to dispose of any remaining liquid after use.

[0019] Furthermore, the motor has a motor shaft, the pump body has a pump shaft, and a quick coupling structure for achieving coaxial connection is provided between the motor shaft and the pump shaft.

[0020] Furthermore, a quick connector is provided between the motor and the power supply.

[0021] Furthermore, a quick connection structure is provided between the motor and the pump body.

[0022] Furthermore, the base is provided with a limiting convex edge that cooperates with the bottom edge of the water tank; or, the base is provided with a second buckle that fixes the water tank.

[0023] Furthermore, a roller is provided at the bottom of the base, a front bracket extending upward is provided at the front side of the base, a handle groove is provided at the upper part of the front bracket, or a shoulder strap is provided on the front bracket.

[0032] The following specific embodiments are used to describe the technical solution of the present invention in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0033] Example 1:

[0034] As shown in Figures 1 to 5, the present invention provides a split-type sprayer, comprising a base 1 with a power supply, a water tank 2 detachably connected to the base 1, a motor 3, a pump body 4, and a spray assembly. The power supply used in this embodiment is a battery, such as a lithium battery, which can be connected to an external 220V power supply for charging. The pump body 4 is mounted on the water tank 2, with the water inlet 42 of the pump body 4 connected to the water tank 2 and the water outlet 43 of the pump body 4 connected to the spray assembly. The pump body 4, water tank 2, and spray assembly together form a replaceable module. The motor 3 is selectively combined with the replaceable module and is detachably connected to the pump body 4. When the water tank 2 and the base 1 are combined, the motor 3 is electrically connected to the power supply and drives the pump body 4 to pump liquid from the water tank 2 and spray it through the spray assembly.

[0035] As shown in Figures 1 and 2, in this embodiment, when the motor 3 is combined with the replaceable module, the motor 3, the pump body 4, the water tank 2, and the spray assembly are combined into one body and installed on the water tank 2. The motor 3 is electrically connected to the power supply to drive the pump body 4 to pump liquid from the water tank 2 and spray it through the spray assembly. Each water tank 2 is provided with a separate pump body 4 and spray assembly. When using different liquids, the replaceable module can be quickly replaced. Multiple water tanks 2 can share a motor 3, which can avoid cross-contamination caused by the solution. There is no need to equip each water tank 2 with a separate motor 3, which greatly reduces costs. At the same time, the pump body 4 and motor 3 are installed as a whole after being combined. The coaxiality between the pump body 4 and the motor 3 is higher. Compared with the prior art in which the motor 3 and the pump body 4 are installed separately on the base 1 and the water tank 2, the separate installation will cause the coaxiality between the pump body 4 and the motor 3 to deviate and decrease. Therefore, the pumping efficiency of the motor 3 combined with the replaceable module is higher. In addition, the installation position of the motor 3 is more flexible, the heat dissipation efficiency of the motor 3 is higher, and the driving energy of the motor 3 can be more effectively transferred to the pump body 4, thereby improving the pumping efficiency.

[0036] The water tank 2 is mechanically but not fluidically connected to the base 1 , and the water tank 2 can be quickly interchanged. The pump can be a double diaphragm pump, a piston pump, or a plunger pump.

[0037] As shown in Figure 2, in one embodiment, a receiving groove 21 for placing the motor 3 and pump body 4 is provided on the outside of the water tank 2. After the motor 3 and the replaceable module are combined, the motor 3 and the pump body 4 are installed in the receiving groove 21 on the outside of the water tank 2, which simplifies the assembly and disassembly process, allowing users to quickly change the water tank 2 to use different liquids. The same motor 3 can be shared to save costs and realize different waterways to spray different liquids. The receiving groove 21 fixes the motor 3 and the pump body 4, ensuring stable operation during use, facilitating continuous liquid spraying, and facilitating quick disassembly and replacement of the motor 3, making the installation of the motor 3 more flexible.

[0038] Among them, the specific position of the receiving tank 21 is not limited. In this embodiment, it can be preferably set on the front side of the water tank 2, and can be hidden in combination with the front bracket 16, which can not only protect the motor 3 and pump body 4 in the receiving tank 21, but also make the appearance more beautiful.

[0039] As shown in Figure 5, in order to connect the motor 3 with the pump body 4 to realize the transmission of the driving energy of the motor 3 to the pump body 4, in one embodiment, the motor 3 has a motor shaft 31, and the pump body 4 has a pump shaft 41. A quick coupling structure for realizing coaxial connection is provided between the motor shaft 31 and the pump shaft 41, which can realize quick connection and coaxial transmission, ensure the high coaxiality between the pump body 4 and the motor 3, effectively reduce the occurrence of faults, and the motor 3 can transmit the power required for the operation of the pump body 4 to the pump body 4 through the quick coupling structure.

[0040] Preferably, in one embodiment, the quick coupling structure comprises a key and keyway. This key and keyway combination provides a stable and quick connection, and features a simple structure for easy operation. When the motor is activated, torque is transmitted from the motor to the pump, and the motor 3 selectively drives the pump body 4 to pump liquid from the water tank 2 and spray it through the spray assembly. In another embodiment, the quick coupling structure comprises a coupling. A first coupling is provided on the pump shaft 41, and a second coupling is provided on the motor shaft 31. The first and second couplings are mated and connected to each other, allowing for rotational connection in at least one rotational direction. In this manner, when the pump shaft 41 and the motor shaft 31 are connected, the first and second couplings are axially aligned and engaged, transmitting torque from the motor 3 to the pump body 4 when the motor 3 is activated. The coupling structure is simple, low-cost, and detachable, making it easy to replace. A variety of coupling models are available, adapting to different types of pump bodies 4 and motors 3 to meet diverse usage requirements. It is understood that other connection methods for quick couplings are also possible and are not limited to these.

[0041] In order to quickly connect the power supply, in one embodiment, a quick connector is provided between the motor 3 and the power supply. By using the quick connector, the motor 3 can be quickly connected to the power supply, which is easy to operate and convenient for quickly replacing the water tank 2 with other liquids.

[0042] In order to quickly connect the motor 3 and the pump body 4 into one body and ensure the stability of the integrated installation, in one embodiment, a quick connection structure is provided between the motor 3 and the pump body 4. The quick connection structure allows the motor 3 and the pump body 4 to be quickly connected together, thereby greatly reducing assembly time and improving spraying efficiency.

[0043] In one embodiment, the quick connection structure can adopt a first clip to fix the motor 3 and the pump body 4 into one. The first clip connection is low in cost and simple to operate. No other auxiliary installation tools are required. The motor 3 and the pump body 4 can be easily fixed and disassembled through the first clip, and the first clip installation has a guiding and positioning function, which further improves the installation efficiency. The first clip also has a self-locking function to prevent the vibration of the motor 3 during operation from causing the connection between the motor 3 and the pump body 4 to become loose, thereby improving the user experience of the liquid sprayer.

[0044] In one embodiment, the quick connection structure can use bolts to secure the motor 3 and pump body 4 together. Bolted connections are more stable and provide a stronger tightening effect, ensuring a secure connection between the motor 3 and pump body 4. It is understood that other quick connection methods can also be used, and are not limited to these.

[0045] To ensure stable installation of water tank 2, in one embodiment, base 1 is provided with a retaining flange 13 that mates with the bottom edge of water tank 2. This flange 13 secures water tank 2 to base 1, ensuring its stability and preventing it from shifting or shaking, which could affect liquid dispensing. The retaining flange 13 also provides a guide for quick installation of water tank 2.

[0046] A tank cover 25 is provided on the top of the water tank 2 , and a cover handle 26 protrudes from the tank cover 25 and can be grasped by a user to lift and carry the water tank 2 .

[0047] In another embodiment, a second clip 14 is provided on the base 1 to fix the water tank 2 , thereby further ensuring the stability of the water tank 2 and firmly and stably fixing the water tank 2 on the base 1 .

[0048] To facilitate mobility, in one embodiment, rollers 15 are provided at the bottom of the base 1. When the water tank 2 is large, the liquid sprayer as a whole is heavy. The rollers 15 at the bottom of the base 1 allow the user to easily and effortlessly push and pull the base 1 to adjust the position of the liquid sprayer, facilitating mobility and improving the user experience.

[0049] In order to facilitate pushing and pulling the liquid sprayer, in one embodiment, the front side of the base 1 is provided with an upwardly extending front bracket 16, and the upper part of the front bracket 16 is provided with a handle groove 17. The handle groove 17 facilitates the user to hold and push the liquid sprayer, making the operation more convenient, comfortable and labor-saving.

[0050] In one embodiment, a shoulder strap 161 is provided on the front frame 16 to facilitate the user to carry and wear the sprayer during operation. The user can manipulate the spray assembly with both hands to apply liquid to the target area. It is understood that the roller 15 can be provided alone, the shoulder strap 161 can be provided alone, or both the roller 15 and the shoulder strap 161 can be provided.

[0051] In one embodiment, a retaining groove 162 is provided on the front bracket 16, and a retaining protrusion 27 is provided on the water tank 2 to cooperate with the retaining groove 162. The retaining groove 162 cooperates with the retaining protrusion 27 to further ensure that the water tank 2 is stably mounted on the base 1, preventing the water tank 2 from shaking or shifting. It will be appreciated that these embodiments may also be implemented in combination.

[0052] Example 2:

[0053] The present invention also provides a split sprayer, comprising a base 1 with a power supply and a motor 3, a water tank 2 detachably connected to the base 1, a pump body 4, and a water system, the water system comprising a water suction component and an injection component, the water inlet 42 of the pump body 4 being connected to the water tank 2 through the water suction component, the water outlet 43 of the pump body 4 being connected to the injection component, the pump body 4 and the water system being combined into a detachable module, the detachable module being detachably mounted on the base 1, the motor 3 being selectively combined with the detachable module, and the motor 3 being detachably connected to the pump body 4, when the water tank 2 and the base 1 are combined together, the motor 3 drives the pump body 4 to pump liquid from the water tank 2 and inject it through the injection component.

[0054] When the motor 3 is combined with the detachable module, the motor 3 is located within the base 1, and the motor 3, pump body 4, and water system are installed in combination on the base 1. When changing the water tank 2 for a different liquid, the pump body 4 and water system are replaced accordingly to avoid cross-contamination of the liquids. The motor 3 can be shared and different water systems can be used to spray different liquids. When using water tanks 2 with different liquids, motors 3 of different powers can also be used to meet different usage needs, which is more flexible and convenient.

[0055] In one embodiment, the base 1 includes a mounting cavity for the motor 3 and pump body 4. Providing a mounting cavity within the base 1 allows for better utilization of internal space, allowing the motor 3 and pump body 4 to be compactly positioned together. This facilitates removal and replacement of the motor 3 and pump body 4. The mounting cavity helps protect the motor 3 and provides a stable support for the motor 3 and pump body 4, helping to reduce vibration and noise during use, providing a better user experience. It also promotes heat dissipation from the motor 3, improving its stability and service life, and enhancing pumping efficiency.

[0056] As shown in Figure 4, when the water tank 2 is assembled with the base 1, in one embodiment, a one-way valve is provided on the water tank 2 to connect the two. The one-way valve comprises a valve port 22, a push rod 23 for opening and closing the valve port 22, and a spring 24 that elastically presses the push rod to close the valve port 22. The base 1 is provided with a protrusion 12 that lifts the push rod 23 to open the valve port 22. When the water tank 2 and the base 1 are assembled, the protrusion 12 lifts the push rod, compressing the spring 24 and opening the valve port 22. Liquid in the water tank 2 can flow through the one-way valve to the pump body 4 for spraying. When the water tank 2 is removed from the base 1, the protrusion 12 moves away from the push rod 23, causing the spring 24 to extend and return the push rod 23 to its original position, closing the valve port 22. In other words, the valve port 22 automatically closes after the water tank 2 leaves the base 1, ensuring that liquid does not overflow from the water tank 2. The water tank 2 may also be provided with a drain port to dispose of any remaining liquid after use.

[0057] In one embodiment, when the motor 3 and pump body 4 are installed in the mounting cavity within the base 1, a water storage cavity may be provided on the base 1. When the valve port 22 is opened, liquid in the water tank 2 flows into the water storage cavity. The water inlet 42 of the pump body 4 is connected to the water storage cavity, and the liquid flows through the water suction assembly to the pump body 4, and then flows through the pump body 4 to the injection assembly for injection. When the motor 3 and pump body 4 are installed in combination within the water tank 2, a water storage tank is not required. The water inlet 42 of the pump body 4 is connected to the water tank 2, and the liquid can flow directly into the pump body 4 to be injected by the injection assembly. Alternatively, a water storage tank may be reserved on the base 1.

[0058] The spray assembly includes a hose and a liquid outlet pipe. One end of the hose is connected to the water outlet 43 of the pump body 4, and the other end is connected to the liquid outlet pipe. A handle is provided at the end of the liquid outlet pipe, which can be used to selectively control the flow of liquid. A pipe clamp 163 is provided on the side of the front bracket 16 to accommodate the liquid outlet pipe when the liquid sprayer is not in use, facilitating storage and transportation.
