Description

Technical Field

[0001] This utility model relates to the field of drain cleaner technology, specifically a multi-purpose drain cleaner. Background Technology

[0002] In daily life and industrial production, pipe blockage and inflation operations (such as the inflation needs of balls, inflatable toys, and small air cushions) are common scenarios, and corresponding unblocking tools and inflation tools are essential auxiliary equipment.

[0003] Currently, most related tools on the market suffer from limited functionality: traditional drain cleaners mostly use the principle of high-pressure gas impact, but their structure is fixed and can only be used for drain blockage scenarios, failing to meet temporary inflation needs; while conventional inflation devices also do not have drain cleaning functions. Users need to purchase drain cleaners and inflation devices separately for different scenarios, which not only increases economic costs but also causes inconvenience in tool storage.

[0004] Meanwhile, in existing electric dredging or air-filling equipment, the lithium batteries used for power supply are mostly fixedly installed. When the lithium battery is depleted, the equipment needs to stop operating and recharge for a long time. It cannot be restored to use by replacing the battery immediately, which seriously affects the efficiency of operation. This defect is even more prominent when dealing with emergency pipe blockages and other scenarios that require continuous operation. Utility Model Content

[0005] In order to overcome the shortcomings of existing technical solutions, this utility model provides a multi-purpose drain cleaner, which can effectively solve the technical problems of single function and limited battery life of current drain cleaners.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A multi-purpose drain cleaner includes a handheld component, the handheld component having a first air pressure chamber inside, and one end of the handheld component having an air inlet communicating with the first air pressure chamber. The first air pressure chamber has an air pressure pump for inflation, and the outside of the handheld component has a pressure relief valve for controlling the depressurization of the first air pressure chamber. It also includes an air pressure hose and an inflation head detachably connected to the handheld component, and one end of the handheld component has a lithium battery detachably installed and electrically connected to the air pressure pump.

[0008] When the handheld device is connected to the air pressure pipe, the air pressure pipe has a second air pressure chamber that communicates with the air inlet. A central delivery pipe is coaxially arranged in the middle of the second air pressure chamber. One end of the central delivery pipe has an air inlet that communicates with the air inlet, and the other end of the central delivery pipe has a first exhaust port that communicates with the outside of the air pressure pipe. The handheld device is detachably equipped with a piston that moves axially inside the air inlet. When the air pressure pump fills the first air pressure chamber, the piston moves toward one end of the air pressure pipe and blocks the air inlet, allowing the gas to flow into the second air pressure chamber simultaneously to form high-pressure gas. When the pressure relief valve controls the first air pressure chamber to depressurize, the piston moves toward one end of the handheld device and opens the air inlet, allowing the high-pressure gas in the second air pressure chamber to be quickly released through the central delivery pipe.

[0009] When the handheld device is connected to the inflation head, the inflation head has a third air pressure chamber that communicates with the air inlet, and the end of the inflation head away from the handheld device has a second exhaust port that communicates with the third air pressure chamber.

[0010] Furthermore, the handheld device has a first connecting part at one end with an air inlet, the air pressure pipe has a second connecting part that works in conjunction with the first connecting part, and the inflation head has a third connecting part that works in conjunction with the first connecting part.

[0011] Furthermore, the handheld device is provided with a battery mounting slot for installing a lithium battery, and the battery mounting slot is provided with a snap-fit ​​part that engages with and secures the lithium battery.

[0012] Furthermore, the end of the handheld component with the air inlet is provided with an annular groove for limiting the movement of the piston component, and the inner diameter of the annular groove is larger than the outer diameter of the piston component.

[0013] Furthermore, the outside of the handheld device is provided with a control key for connecting and controlling the air pump, and an electronic display screen for displaying the internal pressure of the first air chamber.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The drain cleaner provided by this utility model allows for flexible replacement of the air pressure hose and inflation head according to operational needs, resulting in different effects and meeting various usage environments. The detachable lithium battery structure makes it easy to remove and replace from the handheld part, and the drain cleaner can continue to operate without charging, improving ease of use.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1-9As shown, this utility model provides a multi-purpose drain cleaner, which consists of a handheld component 1, an air pump 2, a pressure relief valve 3, an air hose 4, an inflation head 5, a lithium battery 6, a piston component 7, a control key 8, and an electronic display screen 9. The handheld component 1 serves as the main operating unit of the drain cleaner, integrating several key components internally and externally. The air hose 4 and inflation head 5 can be detachably connected to the handheld component 1 according to actual usage needs. The lithium battery 6 provides power for the operation of the air pump 2. The piston component 7 controls the gas flow direction under specific working conditions. The control key 8 and the electronic display screen 9 are used for operation control and pressure monitoring, respectively.

[0032] Inside the handheld component 1, a first air pressure chamber 101 is provided, which provides space for gas storage and initial pressurization. An air pump 2 is fixedly installed inside the first air pressure chamber 101, its function being to fill the first air pressure chamber 101 with air, providing air pressure power for the operation of the entire drain cleaner. One end of the handheld component 1 has an air inlet 102 that communicates with the first air pressure chamber 101, serving as a channel for gas flow between the first air pressure chamber 101 and external components (air pressure pipe 4 or inflation head 5).

[0033] Meanwhile, on the inner side of the end of the handheld component 1 where the air inlet 102 is provided, an axially movable piston component 7 is installed. In order to limit the movement range of the piston component 7, an annular groove 106 is also provided at this end, and the inner diameter of the annular groove 106 is larger than the outer diameter of the piston component 7. This design not only ensures that the piston component 7 can move smoothly in the axial direction, but also avoids the piston component 7 from shifting or falling off during the movement, thus ensuring its stable operation.

[0034] A pressure relief valve 3 is fixedly installed on the outside of the handheld device 1. The pressure relief valve 3 is connected to the first air pressure chamber 101. By operating the pressure relief valve 3, the pressure relief inside the first air pressure chamber 101 can be controlled. In addition, a control key 8 and an electronic display screen 9 are also installed on the outside of the handheld device 1. The control key 8 is connected to the air pressure pump 2. The operator can control the start and stop of the air pressure pump 2 by pressing the control key 8. The electronic display screen 9 is also associated with the first air pressure chamber 101 and is used to display the pressure inside the first air pressure chamber 101 in real time, so that the operator can keep track of the air pressure status in the chamber at any time and make adjustments according to the actual situation.

[0035] On one side of the handheld component 1, a battery mounting slot 104 is provided. The lithium battery 6 is detachably installed in the battery mounting slot 104, and a snap-fit ​​part 105 is provided in the battery mounting slot 104. When the lithium battery 6 is installed in place, the snap-fit ​​part 105 can snap the lithium battery 6 in place and prevent the lithium battery 6 from loosening or falling off due to vibration or other reasons during use. The lithium battery 6 is electrically connected to the air pressure pump 2 through a wire, providing a stable power supply for the continuous operation of the air pressure pump 2. When the lithium battery 6 is depleted, it can be removed from the battery mounting slot 104 for charging or replacement.

[0036] The handheld device 1 has a first connecting part 103 at one end with an air inlet 102, while the air pressure pipe 4 has a second connecting part 405 at one end that works in conjunction with the first connecting part 103. When the air pressure pipe 4 is needed for unblocking operations, the second connecting part 405 on the air pressure pipe 4 is connected to the first connecting part 103 on the handheld device 1, thus achieving a stable assembly of the air pressure pipe 4 and the handheld device 1. After assembly, the second air pressure chamber 401 inside the air pressure pipe 4 remains in a conductive state with the air inlet 102 on the handheld device 1, ensuring smooth gas flow.

[0037] The air pressure pipe 4 has a second air pressure chamber 401 inside. In the middle of the second air pressure chamber 401, a central conveying pipe 402 is coaxially arranged. One end of the central conveying pipe 402 is provided with an air inlet 403, and the other end is provided with a first exhaust port 404. The air inlet 403 corresponds to and is connected to the air outlet 102 of the handheld device 1. The first exhaust port 404 is connected to the outside of the air pressure pipe 4, so that the gas in the central conveying pipe 402 can be discharged to the outside of the air pressure pipe 4.

[0038] When it is necessary to use air pressure hose 4 for unblocking work, such as Figure 1 As shown in the diagram, the operator activates the air pump 2 by pressing the control key 8 on the outside of the handheld device 1. The air pump 2 begins to fill the first air pressure chamber 101 inside the handheld device 1 with air. As the air continuously fills the first air pressure chamber 101, the pressure inside the chamber gradually increases. Under the action of air pressure, the piston 7 located inside the air inlet 102 moves towards one end of the air pressure pipe 4. When the piston 7 moves to be in contact with the air inlet 403 of the middle delivery pipe 402, it blocks the air inlet 403. At this time, the gas in the first air pressure chamber 101 cannot enter the middle delivery pipe 402 through the air inlet 403, but can only flow into the second air pressure chamber 401 of the air pressure pipe 4 through the air inlet 102. As the gas continues to accumulate in the second air pressure chamber 401, high-pressure gas is formed in the second air pressure chamber 401.

[0039] When the high-pressure gas in the second pressure chamber 401 reaches the required pressure (the operator can observe the pressure of the first pressure chamber 101 through the electronic display screen 9; since the first pressure chamber 101 and the second pressure chamber 401 are in a connected state at this time, their pressures are basically the same, and the pressure situation in the second pressure chamber 401 can be judged accordingly), the operation of the air pump 2 is stopped. Subsequently, the pressure relief valve 3 on the outside of the handheld device 1 is operated to control the pressure relief of the first pressure chamber 101. As the pressure in the first pressure chamber 101 decreases, the air pressure thrust on the piston 7 decreases. Under its own weight and the reverse force of the high-pressure gas in the second pressure chamber 401, the piston 7 will move towards one end of the handheld device 1, thereby opening the air inlet 403 of the middle delivery pipe 402. At this time, the high-pressure gas in the second air pressure chamber 401 will quickly enter the middle conveying pipe 402 through the air inlet 403, and then be quickly released to the outside of the air pressure pipe 4 through the first exhaust port 404 at the other end of the middle conveying pipe 402, using the impact force of the high-pressure gas to clear blockages in the pipe and other parts.

[0040] When additional inflation is required, such as Figure 5 As shown in the structure, one end of the inflation head 5 is provided with a third connecting part 503 that cooperates with the first connecting part 103 on the handheld part 1. When it is necessary to use the inflation head 5 for inflation operations (such as inflating balloons, inflatable toys, etc.), the third connecting part 503 on the inflation head 5 is connected to the first connecting part 103 on the handheld part 1 to complete the assembly of the inflation head 5 and the handheld part 1. After assembly, the third air pressure chamber 501 inside the inflation head 5 is kept in communication with the air outlet 102 of the handheld part 1 to ensure that gas can smoothly enter the inflation head 5.

[0041] The inflation head 5 has a third pressure chamber 501 inside. A second exhaust port 502 is located at the end of the inflation head 5 furthest from the handheld component 1, and the second exhaust port 502 is connected to the third pressure chamber 501. After the operator starts the air pump 2, the air pump 2 inflates the first pressure chamber 101. The gas enters the third pressure chamber 501 of the inflation head 5 through the air inlet 102, and then exits through the second exhaust port 502 at one end of the third pressure chamber 501. The second exhaust port 502 is then aligned with the interface of the object to be inflated to complete the inflation operation. During inflation, the operator can observe the pressure in the first pressure chamber 101 in real time through the electronic display screen 9. Based on the required inflation volume and the pressure the object can withstand, the operator can stop the operation of the air pump 2 in a timely manner to complete the inflation work.

[0042] In actual use, the air pressure hose 4 and the inflation head 5 can be flexibly replaced according to operational needs. When switching from using the air pressure hose 4 to using the inflation head 5, simply detach the second connecting part 405 of the air pressure hose 4 from the first connecting part 103 of the handheld part 1, remove the piston part 7, and then connect the third connecting part 503 of the inflation head 5 to the first connecting part 103; conversely, the operation process is similar when switching from using the inflation head 5 to using the air pressure hose 4. When the lithium battery 6 is low on power, it can be directly removed from the battery mounting slot 104 of the handheld part 1 and replaced with a fully charged lithium battery 6, or the removed lithium battery 6 can be charged and then reinstalled for use.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
