Detailed Implementation

[0026] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0027] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0029] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0031] like Figures 1-4 As shown, according to a first aspect of the embodiments of this application, a dust collector is provided, including a body 1 and a connecting pipe 2; a cavity 11 is formed inside the body 1, and a through hole 12 is provided in the body 1, the through hole 12 communicating with the cavity 11, the length of the through hole 12 being greater than the width of the through hole 12; the connecting pipe 2 is disposed outside the cavity 11, the connecting pipe 2 is tangentially connected to the body 1, and the connecting pipe 2 is communicating with the through hole 12.

[0032] like Figures 1-4 As shown, the dust removal hood includes a body 1 and a connecting pipe 2; wherein, the body 1 is used to cover the welding station, the connecting pipe 2 is connected to the cavity 11 of the body 1 through the through hole 12, and the adsorption device is connected to the connecting pipe 2, and the adsorption device adsorbs and removes dust and particulate matter generated during welding.

[0033] To further explain, the interior of the body 1 forms a cavity 11, and a through hole 12 is provided on the body 1. The through hole 12 connects the cavity 11 of the body 1 with the outside of the cavity 11 of the body 1. The connecting pipe 2 is located outside the cavity 11 of the body 1 and is connected to the through hole 12. Therefore, the connecting pipe 2 is connected to the cavity 11.

[0034] The length direction of the through hole 12 refers to the circumferential direction of the body 1. It can be understood as the distance between the two ends of the through hole 12 along the circumferential direction of the body 1, which is opened on the inner wall of the body 1. The width direction of the through hole 12 refers to the axial direction of the body 1. It can be understood as the distance between the two ends of the through hole 12 along the axial direction of the body 1.

[0035] The tangential connection between the connecting pipe 2 and the body 1 means that the axis of the connecting pipe 2 does not coincide with the radial centerline of the body 1.

[0036] To further explain, the length of the through hole 12 is greater than the width of the through hole 12. The connecting pipe 2 is tangentially connected to the body 1, which can increase the dust removal area without increasing the dust removal suction volume. In other words, it effectively increases the contact area with the dust removal hood, increases the probability of particles being absorbed, and thus improves the dust removal efficiency.

[0037] In one alternative embodiment, the through-hole 12 is teardrop-shaped.

[0038] The through-hole 12 is teardrop-shaped, and its rounded shape allows the airflow to transition smoothly when entering the through-hole 12, thereby reducing airflow turbulence and eddies and helping to reduce the impact of airflow on the edge of the through-hole 12. It also allows the gas containing dust to enter the through-hole 12 more smoothly, thereby reducing the escape of dust near the through-hole 12, thus improving the dust collection efficiency and dust removal effect.

[0039] To further explain, compared to other shapes, such as circles or squares, teardrop shapes have better structural strength to a certain extent and can distribute stress more evenly to reduce local stress concentration caused by airflow impact or particle collision, thereby improving the service life of dust collector covers.

[0040] In one optional embodiment, the width of the through hole 12 is 30mm-40mm; specifically, the width of the through hole 12 refers to the distance between the two ends of the farthest end of the through hole 12 in the axial direction of the body 1; the width of the through hole 12 is set between 30mm-40mm, which can ensure the structural strength of the body 1 after the through hole 12 is opened, and can also make the dust removal efficiency of the dust removal hood reach a better state; preferably, the width of the through hole 12 is 35.1mm.

[0041] In one optional embodiment, the dust hood includes four connecting pipes 2; the body 1 has four through holes 12, which are spaced apart circumferentially along the body 1, and the four connecting pipes 2 are respectively connected to the corresponding through holes 12.

[0042] like Figures 1-4 As shown, the dust collector includes four connecting pipes 2, which are spaced apart around the circumference of the body 1; four through holes 12 are provided on the body 1, which are spaced apart around the circumference of the body 1, and one through hole is connected to a corresponding through hole 12; in this embodiment, by providing four connecting pipes 2 and four through holes 12, which are all spaced apart around the circumference of the body 1, the uniformity of dust removal can be improved, so as to prevent the formation of dead corners where dust accumulates.

[0043] In one optional embodiment, the connecting pipe 2 includes a first pipe 21 and a second pipe 22. The first pipe 21 is connected to the through hole 12, and the second pipe 22 is connected to the first pipe 21. The axis of the first pipe 21 intersects the axis of the second pipe 22. In this embodiment, the second pipe 22 is used to connect to the adsorption device so that the connecting pipe 2 can be reasonably arranged in a limited space to connect the dust removal hood and the adsorption device.

[0044] In one alternative embodiment, the axes of the first pipes 21 of two adjacent connecting pipes 2 intersect.

[0045] Among them, such as Figure 4 As shown, the four connecting pipes 2 are the first connecting pipe 2A, the second connecting pipe 2B, the third connecting pipe 2C, and the fourth connecting pipe 2D. The first connecting pipe 2A, the second connecting pipe 2B, the third connecting pipe 2C, and the fourth connecting pipe 2D are arranged in sequence. It can be understood that the first connecting pipe 2A is adjacent to the second connecting pipe 2B and the fourth connecting pipe 2D, the second connecting pipe 2B is adjacent to the first connecting pipe 2A and the third connecting pipe 2C, the third connecting pipe 2C is adjacent to the second connecting pipe 2B and the fourth connecting pipe 2D, and the fourth connecting pipe 2D is adjacent to the third connecting pipe 2C and the first connecting pipe 2A.

[0046] To further explain, such as Figures 2-4 As shown, the axes of the first pipes 21 of two adjacent connecting pipes 2 intersect. Specifically, the axis of the first pipe 21 of the first connecting pipe 2A intersects the axes of the first pipes 21 of the second connecting pipe 2B and the fourth connecting pipe 2D, respectively; the axis of the first pipe 21 of the second connecting pipe 2B intersects the axes of the first pipes 21 of the first connecting pipe 2A and the third connecting pipe 2C, respectively; the axis of the first pipe 21 of the third connecting pipe 2C intersects the axes of the first pipes 21 of the second connecting pipe 2B and the fourth connecting pipe 2D, respectively; and the axis of the first pipe 21 of the fourth connecting pipe 2D intersects the axes of the third pipe of the first connecting pipe 2A and the first pipe 21 of the first connecting pipe 2A, respectively. In this embodiment, it helps to optimize the airflow state within the pipes, reduce airflow turbulence and eddies, thereby reducing energy loss and improving dust removal efficiency.

[0047] In one alternative embodiment, the axes of the first pipes 21 of the two spaced-apart connecting pipes 2 are arranged radially spaced in the body 1.

[0048] To elaborate further, such as Figures 2-4As shown, the first pipes 21 and axes of the two spaced-apart connecting pipes 2 are arranged radially spaced in the body 1. This can be understood as the axes of the first pipes 21 of the first connecting pipe 2A and the third connecting pipe 2C being arranged radially spaced in the body 1, meaning there is a certain distance between them in the radial direction. Similarly, the axes of the first pipes 21 of the second connecting pipe 2B and the fourth connecting pipe 2D are arranged radially spaced in the body 1, meaning there is a certain distance between them in the radial direction. In this embodiment, the axes of the first pipes 21 of the two spaced-apart connecting pipes 2 do not coincide, which optimizes the airflow distribution to avoid convection problems and reduces turbulence and eddies within the pipes. This effectively captures dust, reduces energy loss, and improves airflow uniformity. It also reduces dust deposition within the first pipes 21, thereby reducing the risk of pipe blockage.

[0049] In one alternative implementation, such as Figures 2-4 As shown, the body 1 includes a first port 13 and a second port 14, the diameter of the first port 13 being smaller than the diameter of the second port 14; specifically, the first port 13 and the second port 14 are arranged opposite each other along the axial direction of the body 1, the diameter of the first port 13 being smaller than the diameter of the second port 14, which can be understood as the body 1 being in the shape of a frustum cylinder; when the dust hood is in use, the second port 14 faces the welding station, and the welding device extends from the first port 13 into the cavity 11. The diameter of the second port 14 is larger than the diameter of the first port 13, which can increase the coverage area while reducing the amount of dust leaking out from the first port 13.

[0050] In one optional embodiment, the dust cover further includes a filter assembly disposed inside the body 1 and located at the through hole 12; integrating the filter assembly onto the dust cover can reduce the replacement frequency of the dust cover and lower the maintenance cost of the dust cover.

[0051] According to a second aspect of the embodiments of this application, a welding apparatus is provided, including the dust hood described above.

[0052] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application. The scope of this application is defined by the appended claims.
