Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, specifically a vacuum cleaner with an easily replaceable nozzle. Background Technology

[0002] A quick-change vacuum cleaner nozzle refers to a component on a vacuum cleaner that has a convenient disassembly and installation structure and can replace different functional nozzles in a short time. Its core feature is that by optimizing the interface design (such as snap-on, magnetic, and rotary quick-connect structures), the replacement operation steps and time are reduced.

[0003] In the prior art, such as the quick-change vacuum cleaner nozzle disclosed in CN221044871U, a quick-change vacuum cleaner nozzle is provided. This quick-change vacuum cleaner nozzle is designed by creating a slot and a hole inside the casing, and by adding a locking block and a spring block to the suction rod. During installation, one only needs to hold the spring block with one hand, align the spring block with the locking hole, and align the locking block with the slot. The locking block is then inserted along the slot and moved inward to complete the installation. During disassembly, the spring block is held down, and the suction rod is grasped and the locking block is pulled outward to remove the vacuum cleaner nozzle directly.

[0004] The aforementioned device uses locking blocks and spring blocks for disassembling and installing vacuum cleaner nozzles. Since the locking blocks and spring blocks are located on the upper part of the vacuum cleaner nozzle, the locking blocks need to slide into the inside of the vacuum cleaner nozzle and then slide out to engage with the locking hole. In actual use, when disassembling the vacuum cleaner nozzle, the locking blocks can only be pushed flush with the outer wall of the suction rod by hand, and cannot be directly flush with the inner wall of the casing. Disassembling the vacuum cleaner nozzle requires the use of additional tools to assist in pushing the locking blocks to move. This prevents users from quickly disassembling and replacing the vacuum cleaner nozzle themselves. Therefore, we propose a vacuum cleaner with an easy-to-replace exhaust nozzle. Utility Model Content

[0005] One of the technical problems this application aims to solve is that a single push of the card block cannot make the inner wall of the card block housing flush, which prevents users from quickly disassembling and replacing the vacuum cleaner nozzle themselves.

[0006] To solve the above-mentioned technical problems, this application provides a vacuum cleaner with an easily replaceable exhaust nozzle, including a vacuum cleaner tube, a mounting block, and a suction nozzle. The lower end of the mounting block is sleeved on the lower end of the vacuum cleaner tube, and the suction nozzle is disposed at the lower end of the mounting block. The lower part of the vacuum cleaner tube is provided with a disassembly and assembly component for disassembling and connecting the mounting block.

[0007] Preferably, the assembly / disassembly component includes a knob and a retaining ring that rotate at the lower part of the vacuum cleaner tube. The lower part of the knob is provided with two connecting plates, the lower end of the connecting plates is located at the upper part of the retaining ring, and the upper inner wall of the mounting block is provided with two locking blocks. The lower part of the vacuum cleaner tube and the outer wall of the retaining ring are respectively provided with symmetrically arranged locking groove one and locking groove two, and the locking blocks slide inside the locking groove one.

[0008] Preferably, the upper front and rear sides of the retaining ring are provided with fixing rods, the upper end of the fixing rods is provided with springs, the lower part of the vacuum cleaner tube is provided with two limiting grooves, the fixing rods slide inside the limiting grooves, the end of the spring away from the fixing rods is provided inside the limiting grooves, and the outer wall of the vacuum cleaner tube is provided with a locking member for locking the knob.

[0009] Preferably, the locking element includes a magnet one disposed on the outer wall of the mounting block, a magnet two slidably connected to the outside of the mounting block, a locking block two disposed on the upper part of the magnet two, and the upper end of the locking block two abutting against the lower part of the knob.

[0010] Preferably, the second locking groove is wider at the top and narrower at the bottom, with an inclined chamfer at its central edge, and the length of the space formed by the upper part of the first locking groove and the upper part of the second locking groove is the same as the length of the card block.

[0011] Preferably, the limiting groove is arc-shaped with a radius equal to the rotation radius of the fixed rod, and the limiting groove is stepped with the upper space longer than the lower space.

[0012] Preferably, a locking block is provided inside the second locking groove, and a locking groove is provided on the side of the block near the retaining ring. The shape of the locking groove is matched with that of the first locking block, and the length of the block is the same as the upper part of the first locking groove and the length of the second locking groove.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. During installation, insert the mounting block into the lower part of the vacuum cleaner hose. The inner wall of the mounting block slides in the locking groove one of the vacuum cleaner hose. After reaching the lower part of the locking groove two, turn the knob to drive the retaining ring, so that the locking groove one and the locking groove two are aligned. The mounting block slides into the upper part of the locking groove one. Turn the retaining ring back to lock the lower part of the mounting block to complete the installation. During disassembly, turn the knob in the opposite direction to change the position of the two grooves, release the lock on the mounting block, and let it slide down to remove the mounting block.

[0015] 2. The magnet one on the outer wall of the mounting block and the sliding magnet two have opposite poles facing each other. Magnet one pushes magnet two to slide, causing locking block two to be inserted into the lower part of the knob, restricting the rotation of the knob and preventing the mounting block from loosening due to accidental rotation, thereby ensuring that the air nozzle is firmly and stably connected when the vacuum cleaner is in use.

[0023] 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.

[0024] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a vacuum cleaner with an easy-to-replace air nozzle, including a vacuum cleaner tube 1, a mounting block 11 and a vacuum nozzle 12. The lower end of the mounting block 11 is sleeved on the lower end of the vacuum cleaner tube 1, and the vacuum nozzle 12 is set at the lower end of the mounting block 11. The lower part of the vacuum cleaner tube 1 is provided with a disassembly and assembly part 2 for disassembling and connecting the mounting block 11.

[0025] The vacuum cleaner hose 1 is connected to the vacuum cleaner and is used to connect the mounting block 11 and the vacuum nozzle 12.

[0026] Furthermore, the assembly / disassembly component 2 includes a knob 21 and a retaining ring 22 that rotate at the lower part of the vacuum cleaner tube 1. The lower part of the knob 21 is provided with two connecting plates 24, and the lower end of the connecting plates 24 is provided at the upper part of the retaining ring 22. The upper inner wall of the mounting block 11 is provided with two locking blocks 23. The lower part of the vacuum cleaner tube 1 and the outer wall of the retaining ring 22 are respectively provided with symmetrically arranged locking groove 1 25 and locking groove 26. The locking blocks 23 slide inside the locking groove 1 25.

[0027] The knob 21 can drive the retaining ring 22 to rotate through the connecting plate 24. The retaining ring 22 and the locking groove 1 25 and locking groove 26 opened on the outer wall of the vacuum cleaner tube 1 together form the sliding locking space of the retaining block 23. The retaining block 23 can slide inside the locking groove 1 25 and locking groove 26. The width of the space of the locking groove 1 25 and locking groove 26 is the same as that of the retaining block 23. The retaining block 23 cannot move left or right when sliding. When the mounting block 11 is inserted into the lower part of the vacuum cleaner tube 1, the retaining block 23 slides inside the locking groove 1 25. When the retaining block 23 is against the lower part of the locking groove 26, the retaining ring 22 is rotated to make the locking groove 26 and locking groove 1 25 overlap. The retaining block 23 can continue to slide upward through the locking groove 26 and then insert into the upper part of the locking groove 1 25. The retaining ring 22 rotates back to make the upper part of the locking groove 26 lock in the lower part of the retaining block 23, thereby realizing the installation of the mounting block 11.

[0028] Furthermore, the upper front and rear sides of the retaining ring 22 are provided with fixing rods 29, the upper end of the fixing rods 29 is provided with springs 210, the lower part of the vacuum cleaner tube 1 is provided with two limiting grooves 211, the fixing rods 29 slide inside the limiting grooves 211, the end of the springs 210 away from the fixing rods 29 is provided inside the limiting grooves 211, and the outer wall of the vacuum cleaner tube 1 is provided with locking members 3 for locking the knob 21;

[0029] Rotating the knob 21 causes the retaining ring 22 to rotate, which in turn causes the fixed rod 29 to slide and compress the spring 210 to contract. When the fixed rod 29 slides to the lower part of the limiting groove 211, the fixed rod 29 can no longer slide. Then the spring 210 rebounds and pushes the fixed rod 29 back to its original position, thereby realizing the sliding and return of the retaining ring 22.

[0030] Furthermore, the locking element 3 includes a magnet 31 disposed on the outer wall of the mounting block 11, a magnet 32 ​​slidably connected to the outside of the mounting block 11, a locking block 33 disposed on the upper part of the magnet 32, and the upper end of the locking block 33 abutting against the lower part of the knob 21.

[0031] Furthermore, the shape of the limiting groove 211 is an arc, and its radius is the rotation radius of the fixed rod 29. The shape of the limiting groove 211 is stepped, and the upper space is longer than the lower space.

[0032] Magnet 1 31 and Magnet 2 32 are arranged with opposite poles facing each other. Magnet 2 32 can slide. Magnet 1 31 pushes Magnet 2 32 to slide. Magnet 2 32 can drive Locking Block 2 33 to be inserted into the lower part of Knob 21, thereby restricting the rotation of Knob 21 and locking Knob 21.

[0033] Furthermore, the second locking groove 26 is wider at the top and narrower at the bottom, with an inclined chamfer at its middle edge. The length of the space formed by the upper part of the first locking groove 25 and the upper part of the second locking groove 26 is the same as the length of the locking block 23.

[0034] When the locking block 23 is inserted into the upper part of the locking slot 25, the space formed by the upper part of the locking slot 25 and the upper part of the locking slot 26 can completely lock the locking block 23, preventing the locking block 23 from moving.

[0035] Example 2: Please refer to Figure 5 and Figure 6 Based on embodiment 1, this utility model provides another technical solution: a locking block 27 is provided inside the locking groove 26, and a locking groove 28 is provided on the side of the locking block 23 near the locking ring 22. The shape of the locking groove 28 matches the locking block 27, and the length of the locking block 23 is the same as the upper part of the locking groove 25 and the length of the locking groove 26.

[0036] The upper spaces of locking slot 26 and locking slot 1 25 can provide complete accommodation space for the locking block 23. At the same time, the upper space of locking slot 1 25 can be locked on the upper part of the locking block 23 to prevent the retaining ring 22 from turning over and to reduce the pressure load on locking block 2 33. Locking block 1 27 can be locked inside locking slot 3 28 to prevent the mounting block 11 from falling downward.
