In this way, the top of the mounting base 1 is detachably fixed to one of the external products or devices that need to be fixed, and the lower part of the connecting head assembly 10 is detachably fixed to another external product or device that needs to be fixed. Of course, the installation positions of the mounting base 1 and the connecting head assembly 10 can also be interchanged. The main purpose is to connect and fix two external products or devices together. This external product or device can be a range hood and an oil net, or a range hood and an oil baffle, or some other two matching parts that need to be fixedly connected.The top of the mounting base 1 and the bottom of the connector assembly 10 are fixed to two external products or devices respectively, and the mounting base 1 is surrounded by a first cavity that runs through the top and the bottom, giving the connector assembly 10 an upward thrust so that the upper part of the connector assembly 10 can be inserted into the first cavity from the bottom of the mounting base 1. The mounting base 1 is provided with the guide portion 22 and the clamping portion 23 at intervals on the middle upper side and the middle lower side at the corresponding position of the first cavity, and the left end of the clamping portion 23 is aligned with the left part of the guide portion 22, that is, the left end of the clamping portion 23 is located at the guide The left end of the part 22 is slightly offset to the right, so that the clamping part 23 and the guide part 22 are slightly offset, and the upper spacer ring of the connector assembly 10 is provided with the guide strip 21, the position of the guide strip 21 corresponds to the position of the guide part 22, and the through groove 24 is sandwiched between two adjacent clamping parts 23. The corresponding position below the clamping part 23 is integrally fixed with a carry groove 30, the carry groove 30 is connected with the through groove 24, and the carry groove 30 is releasably abutted against the top of the guide strip 21. In this way, when the upper part of the connector assembly 10 is inserted into the mounting seat 1 When the guide bar 21 is in the lower position, the top of the guide bar 21 first abuts against the carry slot 30, and the guide bar 21 is guided into the through slot 24 by the carry slot 30, so that the guide bar 21 can slide in along the through slot 24. During the sliding in process, the top of the guide bar 21 is aligned with the left part of the guide portion 22. After the guide bar 21 slides in, the top of the connector assembly 10 elastically abuts against the top of the mounting seat 1. After the connector assembly 10 is inserted into the mounting seat 1 to the maximum extent, the guide bar 21 is released from abutment with the through slot 24, and the through slot 24 is sandwiched between two adjacent The guide strip 21 is between the clamping parts 23, so the guide strip 21 has not yet abutted against the clamping part 23 at this time, and the guide part 22 guides the guide strip 21 to align with the left part of the clamping part 23, releases the thrust on the connector assembly 10, and utilizes the elastic force of the mounting seat 1 on the top of the connector assembly 10 to slide the bottom of the guide strip 21 into the left part of the clamping part 23, and utilizes the elastic force and the self-gravity of the connector assembly 10 and the external product to make the guide strip 21 and the left part of the clamping part 23 releasably clamped and fixed, thereby fixing two external products or devices that need to be connected together.When it is necessary to separate the two fixed external products or devices, an upward thrust is applied to the connector assembly 10, so that the top of the guide strip 21 is disengaged from the left part of the clamping part 23, and then moves upward to abut against the right part of the guide part 22. The right part of the guide part 22 guides the guide strip 21 to align with the right part of the clamping part 23, and the thrust on the connector assembly 10 is released. The elastic force of the bottom of the mounting seat 1 on the connector assembly 10 is used to make the bottom of the guide strip 21 abut against the right part of the clamping part 23. The right part of the clamping part 23 guides the guide strip 21 into the through slot 24. The guide strip 21 drives the connector assembly 10 to slide out along the through slot 24, and the two connected external products or devices are separated. The advantages of the quick-release device for range hoods of the present invention over the prior art are: simple structure, small size, light weight, low price, more convenient disassembly and assembly and after-sales service, and longer service life.

[0042] The quick-release device of the range hood of the present invention is shown in FIG. Figures 1 to 6 In the relevant figures, on the basis of the previous technical solution, the width of the through slot 24 can be 1-2 mm greater than the width of the guide bar 21. In this way, the width of the through slot 24 is greater than the width of the guide bar 21, which can facilitate the sliding of the guide bar 21 in the through slot 24, and can also prevent the guide bar 21 from deviating from the left position of the guide part 22, so that the guide bar 21 can be smoothly aligned with the left part of the guide part 22 in the through slot 24.

[0043] The quick-release device of the range hood of the present invention is shown in FIG. Figures 1 to 6In the relevant figures, on the basis of the previous technical solution, it can also be that: the guiding portion 22 includes a first groove 13 arranged on the left side for guiding the guide strip 21, the clamping portion 23 includes a clamping groove 15 arranged on the left side for clamping and fixing the guide strip 21, the left end of the clamping groove 15 is aligned with the left part of the first groove 13, the top of the guide strip 21 is releasably abutted against the first groove 13, and the bottom of the guide strip 21 is releasably clamped and fixed to the clamping groove 15. In this way, during the sliding process, the top of the guide strip 21 is aligned with the left part of the first groove 13. After the guide strip 21 slides in, the top of the connector assembly 10 elastically abuts against the top of the mounting seat 1. After the connector assembly 10 is inserted into the mounting seat 1 to the maximum extent, the guide strip 21 and the through groove 24 are released from abutment. The through groove 24 is sandwiched between two adjacent clamping portions 23. Therefore, the guide strip 21 has not yet abutted against the clamping portion 23 at this time. The groove 13 guides the guide bar 21 to align with the left part of the positioning groove 15, releases the thrust on the connector assembly 10, and uses the elastic force of the mounting seat 1 on the top of the connector assembly 10 to slide the bottom of the guide bar 21 into the left part of the positioning groove 15. The elastic force and the self-weight of the connector assembly 10 and the external product are used to make the guide bar 21 and the left part of the positioning groove 15 releasably clamped and fixed, thereby fixing two external products or devices to be connected together. A further preferred technical solution is that the first groove 13 includes a first upper bevel 17 on the left side, the first upper bevel 17 extends obliquely upward from the bottom of the first groove 13 to the top of the first groove 13 from left to right, and the positioning groove 15 includes a first lower bevel 18 on the right side, the first lower bevel 18 extends obliquely downward from the top of the positioning groove 15 to the bottom of the positioning groove 15 from left to right, and the left end of the first lower bevel 18 is aligned with the first upper bevel 17. In this way, the first lower bevel 18 extends obliquely upward from left to right from the bottom of the first groove 13 to the top of the first groove 13, and the first lower bevel 18 extends obliquely downward from left to right from the top of the locking groove 15 to the bottom of the locking groove 15. In this way, when the first upper bevel 17 guides the guide strip 21, the guide strip 21 slides obliquely upward along the first upper bevel 17 to the top of the first groove 13 and then stops sliding, and the connector assembly 10 is released to use elastic force to push the guide strip 21 into the first lower bevel 18. The first lower bevel 18 guides the guide strip 21 into the bottom of the locking groove 15, and uses elastic force to abut the bottom of the guide strip 21 against the bottom of the locking groove 15, thereby preventing the connector assembly 10 from easily slipping out of the mounting seat 1, causing the connection between the two external products or devices to fail.A further preferred technical solution is that the cross section of the first groove 13 is an isosceles triangle, the first upper hypotenuse 17 is the left side of the isosceles triangle, the base angle of the isosceles triangle is set to 30-60°, the cross section of the positioning groove 15 is a right triangle, the first lower hypotenuse 18 is the hypotenuse located on the right side of the right triangle, and the bottom acute angle of the right triangle is set to 40-70°. In this way, the top of the first groove 13 is the vertex of the isosceles triangle, and its right side can more accurately align the bottom of the guide strip 21 with the first lower hypotenuse 18, so that the guide strip 21 can smoothly slide into the first lower hypotenuse 18 after being guided by the first groove 13, and will not be unable to correctly insert into the positioning groove 15 due to excessive rotation. A further preferred technical solution is that the base angle of the first groove 13 is set to 60°, and the bottom acute angle of the positioning groove 15 is set to 45°. In this way, the cross section of the first groove 13 is an equilateral triangle, the cross section of the positioning groove 15 is a right-angled isosceles triangle, and the first upper bevel 17 and the first lower bevel 18 respectively guide the guide direction of the guide strip 21 more smoothly.

[0044] The quick-release device of the range hood of the present invention is shown in FIG. Figures 1 to 6In the relevant figures, on the basis of the previous technical solution, it can also be that: the guiding portion 22 also includes a second groove 14 arranged on the right side for guiding the guide bar 21, the clamping portion 23 includes an exit groove 16 arranged on the right side for guiding the guide bar 21, the exit groove 16 is connected to the through groove 24, the left end of the exit groove 16 is aligned with the left part of the second groove 14, the top of the guide bar 21 is releasably abutted against the second groove 14, and the bottom of the guide bar 21 is releasably abutted against the exit groove 16. In this way, when it is necessary to separate the two fixed external products or devices, an upward thrust is given to the connector assembly 10, so that the top of the guide strip 21 disengages from the locking groove 15 and abuts against it, and after moving upward, it abuts against the left part of the second groove 14. The left part of the second groove 14 guides the guide strip 21 to be aligned with the left part of the exit groove 16, and the thrust on the connector assembly 10 is released. The elastic force of the bottom of the mounting seat 1 on the connector assembly 10 is used to make the bottom of the guide strip 21 abut against the left part of the exit groove 16. The left part of the exit groove 16 guides the guide strip 21 into the through groove 24, and the guide strip 21 drives the connector assembly 10 to slide out along the through groove 24, and the two connected external products or devices are separated. A further preferred technical solution is that the second groove 14 includes a second upper bevel 19 on the left side, and the second upper bevel 19 extends obliquely upward from left to right from the bottom of the second groove 14 to the top of the second groove 14, and the exit groove 16 includes a second lower bevel 20 on the right side, and the second lower bevel 20 extends obliquely downward from left to right from the top of the exit groove 16 to the bottom of the exit groove 16, and the left end of the second lower bevel 20 is aligned with the first upper bevel 17. In this way, the second upper bevel 19 extends obliquely upward from left to right from the bottom of the second groove 14 to the top of the second groove 14, and the exit groove 16 includes a second lower bevel 20 on the right side, and the second lower bevel 20 extends obliquely downward from left to right from the top of the exit groove 16 to the bottom of the exit groove 16, so that when the guide bar 21 slides into the second groove 14, the second upper bevel 19 guides the guide bar 21, and the guide bar 21 slides obliquely upward along the second upper bevel 19 to the top of the second groove 14 and then stops sliding, and the connector assembly 10 is released to use elastic force to push the guide bar 21 into the second lower bevel 20, and the second lower bevel 20 guides the guide bar 21 into the through groove 24, and uses elastic force to make the guide bar 21 slide out smoothly along the through groove 24, thereby avoiding the problem that two external products or devices cannot be smoothly disassembled.A further preferred technical solution is that the cross section of the second groove 14 is an isosceles triangle, the second upper hypotenuse 19 is the left side of the isosceles triangle, the bottom angle of the isosceles triangle is set to 30-60°, the cross section of the positioning groove 15 is a right triangle, the second lower hypotenuse 20 is the hypotenuse located on the right side of the right triangle, and the bottom acute angle of the right triangle is set to 40-70°. In this way, the top of the second groove 14 is the vertex of the isosceles triangle, and its right side can align the bottom of the guide strip 21 with the second lower hypotenuse 20 more accurately, so that the guide strip 21 can slide smoothly into the second lower hypotenuse 20 after being guided by the second upper hypotenuse 19, and will not be unable to correctly insert into the exit groove 16 due to excessive rotation, thereby ensuring that the connector assembly 10 can slide out of the through groove 24 smoothly. A further preferred technical solution is that the bottom angle of the second groove 14 is set to 60°, and the bottom acute angle of the exit groove 16 is set to 45°. In this way, the cross section of the second groove 14 is an equilateral triangle, the cross section of the exit groove 16 is a right-angled isosceles triangle, and the second upper bevel 19 and the second lower bevel 20 respectively guide the guide direction of the guide bar 21 more smoothly. A further preferred technical solution is that the left right-angled side of the exit groove 16 is aligned with the right side of the second groove 14. In this way, a thrust is given to the connector assembly 10, so that the guide bar 21 can move up along the left right-angled side of the exit groove 16 until it smoothly abuts against the second upper bevel 19.

[0045] The quick-release device of the range hood of the present invention is shown in FIG. Figures 1 to 6In the relevant figures, on the basis of the previous technical scheme, it can also be that: the mounting seat 1 includes a limiting sleeve 3 for the connecting head assembly 10 to slide and a guide column 5 detachably fixed to the upper part of the limiting sleeve 3, the guide column 5 is accommodated in the upper part of the first cavity and is surrounded to form a second cavity, the top of the connecting head assembly is elastically and releasably abutted against the top of the mounting seat 1 through the second cavity, the limiting sleeve 3 is surrounded to form the lower part of the first cavity, the guide portion 22 is integrally formed or fixed on the bottom outer periphery of the guide column 5, and the clamping portion 23 is integrally formed or fixed on the lower inner periphery of the limiting sleeve 3.

In addition, the top of the connector assembly can be elastically releasably offset against the top of the mounting seat 1 in any manner, such as extending the top of the connector assembly, or arranging any parts in the second cavity, as long as the top of the connector assembly can be directly elastically offset against the top of the mounting seat 1. A further preferred technical solution is that the upper outer circumference of the guide column 5 is integrally formed with a fixed limiting rib 12, and the upper inner circumference of the limiting sleeve 3 is integrally formed with a fixed limiting groove 11 at the corresponding position of the limiting rib 12, and the limiting rib 12 and the limiting groove 11 are releasably abutted. In this way, when the limiting rib 12 abuts against the limiting groove 11, the limiting groove 11 limits the limiting rib 12, that is, the limiting groove 11 limits the guide column 5 in the circumferential direction, preventing the limiting sleeve 3 and the guide column 5 from relative movement in the circumferential direction, thereby avoiding the relative position of the guide portion 22 and the clamping portion 23 from changing, ensuring that even if the mounting seat 1 is divided into two parts, namely, the limiting sleeve 3 and the guide column 5, the connector assembly 10 and the mounting seat 1 can be fixedly connected and disassembled smoothly.

[0046] The quick-release device of the range hood of the present invention is shown in FIG.

In this way, the top column 4 can prevent the upper parts thereof from interfering with the top of the connector assembly 10, thereby affecting the smooth abutment between the guide bar 21 and the guide portion 22 or the guide bar 21 cannot smoothly slip off from the through groove 24. A further preferred technical solution is that the mounting seat 1 also includes an elastic component 6, the upper end of the elastic component 6 is detachably fixed to the top of the mounting seat 1, and the lower end of the elastic component 6 is detachably fixed to the top of the top column 4. In this way, the upper end of the elastic component 6 is detachably fixed to the top of the mounting seat 1, and the lower end of the elastic component 6 is detachably fixed to the top of the top post 4. The upper parts of the elastic component 6 and the top post 4 are contained in the second cavity. The top post 4 can extend into the first cavity through the bottom of the second cavity. The top post 4 is elastically and detachably connected to the top of the mounting seat 1 through the elastic component 6, so that when the connector assembly 10 and the top of the mounting seat 1 are elastically abutted, the elastic component 6 can be squeezed by the top post 4, so that the elastic component 6 generates elastic force and does not interfere with the top of the connector assembly 10. The elastic component 6 can be a spring or the like. A further preferred technical solution is that the mounting seat 1 also includes a fixed disk 2 arranged at the top, the upper end of the elastic component 6 is detachably fixed to the fixed disk 2, the fixed disk 2 is detachably fixed to the top of the limiting sleeve 3, and the top of the guide post 5 is releasably abutted against the fixed disk 2. In this way, when the mounting base 1 is disassembled from the external product or device to be connected, the fixing plate 2 prevents the elastic component 6 from sliding down from above the mounting base 1, thereby preventing the various components in the limiting sleeve 3 from being scattered on the ground during transportation or falling. The fixing plate 2 can also be provided with at least four first screw holes 27 and at least two second screw holes 28 at equal intervals, the second screw holes 28 are used for detachable fixation with the limiting sleeve 3, and the first screw holes 27 are used for detachable fixation with the external product or device. In this way, the first screw holes 27 are evenly distributed on the outer circumference of the fixing plate 2, and the fixing plate 2 and the external product or device are firmly fixed in the circumferential direction, and the second screw holes 28 fix the fixing plate 2 and the limiting sleeve 3 in the circumferential direction.

In this way, the diameter of the top column 25 is larger than the diameter of the bottom column 26, and the bottom column 26 can pass through the bottom of the guide column 5, while the top surface of the top column 25 is elastically releasably abutted against the top of the mounting seat 1, and the bottom surface of the top column 25 is releasably abutted against the lower part of the guide column 5. In this way, the bottom surface of the top column 25 is clamped on the lower part of the guide column 5, and the top of the connector assembly 10 can be repeatedly releasably abutted against the bottom of the bottom column 26 during use, preventing the components above the top column 25 from interfering with the connector assembly 10, thereby affecting the smoothness of the entry and exit of the connector assembly 10. A further preferred technical solution is that the guide column 5 is integrally formed with an annular step surface 29 fixed above the guide portion 22, the inner diameter of the step surface 29 is smaller than the diameter of the top column 25, and the upper part of the top column 4 is releasably abutted against the step surface 29. In this way, the inner diameter of the step surface 29 is smaller than the diameter of the push column 25. When the push column 4 pushes the connector assembly 10 downward, the bottom of the push column 25 is clamped above the guide portion 22 to prevent the push column 4 and the components above the push column 4 from sliding out of the guide column 5, thereby preventing interference with the connector assembly 10.

[0048] The quick-release device of the range hood of the present invention is shown in FIG. Figures 1 to 6 In the relevant figures, on the basis of the previous technical solution, it can also be: the connector assembly 10 includes an upper rotating head 8 and a lower fixed shaft 9, the guide strip 21 spacer ring is arranged on the outer periphery of the rotating head 8, the rotating head 8 and the mounting seat 1 are detachably slidably connected in the first cavity, the bottom of the rotating head 8 is detachably fixed to the top of the fixed shaft 9, and the outer periphery of the fixed shaft 9 is detachably fixed to an external product or device.
