Description

Technical Field

[0001] This invention relates to the field of fire extinguishing technology, and in particular to a split-type handheld fire extinguisher. Background Technology

[0002] Handheld fire extinguishers are the most common firefighting equipment on the market, used to extinguish initial fires and effectively reduce loss of life and property. They can be categorized into dry powder, water-based, and carbon dioxide fire extinguishers, depending on the application scenario. Each has its own advantages and disadvantages. However, they are all stored in high-pressure containers, which limits their usage time to the internal storage space of the container. Furthermore, as the internal pressure gradually decreases, the spray pressure also gradually decreases, and their functionality is quite limited. Summary of the Invention

[0003] The technical problem that this invention aims to solve is that the spray pressure of current handheld fire extinguishers is gradually decreasing, and their functionality is also very limited.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a split handheld fire extinguisher, including a main tank, a spray handle, a spray pipe and a nozzle. The main tank has outwardly protruding side mounting seats at both the upper and lower ends. The spray handle is installed on the side mounting seat at the upper end of the main tank. A split centrifugal booster pump is fixedly installed on the side mounting seat at the lower end of the main tank. A side-mounted guide pipe connected to the air outlet of the split centrifugal booster pump is fixedly installed on the outer wall of the main tank.

[0005] The lateral mounting base is equipped with a manual control valve inside, and the side wall of the lateral mounting base is equipped with an elastic lateral locking block and an external adjusting tooth block for controlling the manual control valve.

[0006] The main tank body is equipped with end discharge ports on the side mounting seats at both the upper and lower ends.

[0007] The lower end of the injection handle and the upper and lower ends of the split centrifugal booster pump are both provided with mounting slots that mate with the lateral mounting base.

[0008] The mounting slot has a lateral limiting through hole that cooperates with the elastic lateral locking block and a lateral control through hole that cooperates with the external adjusting tooth block.

[0009] A lateral control valve for connecting a side-mounted guide pipe is installed on the side wall of the injection pressure handle.

[0010] Both the lateral limiting through hole and the lateral control through hole are elastically fitted with external control blocks.

[0011] An external knob is axially fixed to the outer end of the external control block inside the lateral control through hole.

[0012] The lateral control valve is equipped with a push-button switch for controlling the split-type centrifugal booster pump.

[0013] The side-mounted guide pipe is an internally pressurized guide pipe.

[0014] The beneficial effects of this invention are: (1) The split handheld fire extinguisher of the present invention sets the main tank and the spray handle as a split structure, which can be quickly separated and replaced after use, thereby improving its recycling rate and reducing recycling and use costs; (2) By fixing a split centrifugal booster pump on the side mounting seat at the lower end of the main tank, it can not only connect the air outlet of the split centrifugal booster pump through the side-mounted guide pipe on the outer wall of the main tank to increase the spray pressure by bottom boosting, but also fully utilize the fire extinguishing materials inside by opening the bottom, thereby improving resource utilization. (3) By using the mounting slots at the upper and lower ends of the split centrifugal booster pump, multiple main tanks can be connected in series, thereby greatly increasing the capacity of the fire extinguisher; (4) By using a split centrifugal booster pump, not only can the internal pressure be boosted, but a high-pressure dust blowing mechanism can also be formed to blow out surface impurities or dust, making it easier to clean later and improving functionality.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] Figure 1 , Figure 2 , Figure 3 and Figure 4 The illustrated split-type handheld fire extinguisher includes a main tank 1, a spray handle 2, a nozzle 3, and a nozzle 4. The main tank 1 has outwardly protruding side mounting seats 5 at both the upper and lower ends. The spray handle 2 is mounted on the side mounting seat 5 at the upper end of the main tank 1. A split-type centrifugal booster pump 6 is fixedly mounted on the side mounting seat 5 at the lower end of the main tank 1. A side-mounted guide pipe 7 connected to the air outlet of the split-type centrifugal booster pump 6 is fixedly mounted on the outer wall of the main tank 1.

[0024] To facilitate installation and internal control, the side mounting base 5 is equipped with a manual control regulating valve 51, and the side wall of the side mounting base 5 is equipped with an elastic lateral locking block 52 and an external adjusting tooth block 53 for controlling the manual control regulating valve 51.

[0025] To facilitate end flow guidance, end discharge ports are provided on the side mounting seats 5 at the upper and lower ends of the main tank body 1.

[0026] To facilitate assembly, the lower end of the injection handle 2 and the upper and lower ends of the split centrifugal booster pump 6 are provided with mounting slots that mate with the side mounting base 5.

[0027] To facilitate limiting and controlling, the mounting slot is provided with a lateral limiting through hole that cooperates with the elastic lateral locking block 52 and a lateral control through hole that cooperates with the external adjusting tooth block 53.

[0028] To facilitate the lateral connection assembly, a lateral control valve 21 for connecting the side-mounted guide pipe 7 is installed on the side wall of the injection handle 2.

[0029] For ease of control, external control blocks 8 are elastically fitted inside both the lateral limiting through-hole and the lateral control through-hole.

[0030] The external control block 8 inside the lateral limiting through hole can separate the elastic lateral locking block 52 from the lateral limiting through hole by squeezing inward, thereby quickly separating the injection handle 2 from the lateral mounting seat 5 and the lateral mounting seat 5 from the split centrifugal booster pump 6.

[0031] To facilitate external adjustment, an external knob 81 is axially fixed at the outer end of the external control block 8 inside the lateral control through hole.

[0032] First, the injection handle 2 is installed on the side mounting seat 5 at the upper end of the main tank 1, and the split centrifugal booster pump 6 is installed on the side mounting seat 5 at the lower end of the main tank 1. The elastic side locking block 52 is inserted into the side limiting through hole to complete the limiting. Then, the external knob 81 is pressed to control the end of the external control block 8 inside the side control through hole to mesh with the external adjusting tooth block 53. Then, the external knob 81 is rotated to drive the external adjusting tooth block 53 to rotate, thereby controlling the manual regulating valve 51 to start or close.

[0033] To facilitate automatic start-up control, a push-button switch 22 for controlling the split-type centrifugal booster pump 6 is installed inside the side control valve 21.

[0034] When the lateral control valve 21 is manually started, the internal valve opens. Pressing the switch 22 squeezes the valve, controlling the split centrifugal booster pump 6 to start, and the split centrifugal booster pump 6 begins to rotate at high speed.

[0035] To enhance the boosting effect, the side-mounted guide pipe 7 is an internal boosting guide pipe.

[0036] The internal pressurization guide pipe is equipped with an elastic pressurization tube. When the split centrifugal pressurization pump 6 rotates at high speed to inflate the side-mounted guide pipe 7, it controls the elastic pressurization tube to expand and deform outward. The deformation stores the internal pressure. Then, when the side control valve 21 is opened, the injection pressure handle 2 is opened. After that, the elastic pressurization tube will squeeze the internal fluid, release the stored energy, and assist in pressurization.

[0037] Work process Take out the main tank 1, the injection handle 2, and the split centrifugal booster pump 6. Align the mounting slot at the lower end of the injection handle 2 with the lateral mounting seat 5 at the upper end of the main tank 1, and slowly slide it in until it fits. At this time, the elastic lateral locking block 52 on the side wall of the lateral mounting seat 5 is squeezed and contracted by the mounting slot. When it reaches the lateral limit through hole position, the elastic lateral locking block 52 pops out and locks into the through hole, thus completing the fixation of the injection handle 2 and the main tank 1.

[0038] Similarly, align the mounting slot at the upper end of the split centrifugal booster pump 6 with the lateral mounting seat 5 at the lower end of the main tank 1, and then fit it in to achieve fixation through the cooperation of the elastic lateral locking block 52 and the lateral limiting through hole.

[0039] Check the connection status of the side-mounted guide pipe 7, ensuring that one end is connected to the air outlet of the split centrifugal booster pump 6, and the other end is firmly connected to the lateral control valve 21 on the side wall of the injection handle 2, with no air leakage gaps.

[0040] Press the external knob 81 to engage the end of the external control block 8 in the lateral control through hole with the external adjusting tooth block 53 on the lateral mounting base 5; rotate the external knob 81 to drive the external adjusting tooth block 53 to rotate, thereby controlling the manual control valve 51 to open (fire extinguishing mode) or close (dust blowing mode). After debugging, release the external knob 81 and the external control block 8 will elastically reset and disengage.

[0041] If expansion is required, a new main tank 1 is inserted into the mounting slot at the lower end of the already assembled split centrifugal booster pump 6. It is then fixed to the side limit through hole by the elastic side locking block 52. Repeated operation can connect multiple main tanks 1 in series. After connecting in series, ensure that all manual control valves 51 are in the open state to ensure the flow of fire extinguishing materials.

[0042] Hold the main tank 1 and aim the nozzle 4 at the fire source; manually open the side control valve 21. During the valve opening process, squeeze the internal push switch 22 to trigger the split centrifugal booster pump 6 to start.

[0043] The split-type centrifugal booster pump 6 rotates at high speed, filling the side-mounted guide pipe 7 with air, causing the internal elastic booster pipe to expand and store energy; at the same time, the fire extinguishing material in the main tank 1, under the combined action of its own pressure and the booster pump, enters the spray handle 2 through the end discharge port of the upper side mounting seat 5.

[0044] Press the spray handle 2 to open the internal channel. The elastic booster tube in the side-mounted guide pipe 7 resets and releases the stored energy. After mixing with the fire extinguishing material, it is sprayed out at high speed through the nozzle 3 and nozzle 4 to achieve fire extinguishing operation. During the operation, the split centrifugal booster pump 6 runs continuously to supplement the pressure and ensure stable spray pressure.

[0045] If dust blowing is required, rotate the external knob 81. Through the meshing transmission between the external control block 8 and the external adjusting tooth block 53, close the manual regulating valve 51 in the side mounting seat 5 of the main tank 1, and cut off the raw material channel between the main tank 1 and the injection pressure bar 2.

[0046] Open the side control valve 21 and start the split centrifugal booster pump 6 by pressing the switch 22. The high-pressure airflow generated by the booster pump directly enters the side-mounted guide pipe 7 and is sprayed out through the spray pipe 3 and nozzle 4 to blow away impurities or dust from the area to be cleaned.

[0047] After the fire extinguishing material is exhausted, squeeze the external control block 8 at the mounting slot of the spray handle 2 to cause the elastic lateral locking block 52 to retract and disengage from the lateral limiting through hole, and remove the spray handle 2 from the lateral mounting seat 5 at the upper end of the main tank 1; similarly, squeeze the external control block 8 at the mounting slot at the upper end of the split centrifugal booster pump 6 to separate the main tank 1 from the booster pump.

[0048] Replace the main tank 1 with a new one filled with extinguishing material, and reconnect the spray handle 2 and the split centrifugal booster pump 6 according to the assembly steps, and it can be put into use again; if it is no longer needed, separate and store the components to reduce storage space.

[0049] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
