[0047] Embodiment 1

[0048] Please refer to Figures 1 to 9 , the embodiment of the present utility model provides a direct insertion type air shower nozzle 100, which is assembled on the mounting hole wall 4 of an air shower room (not shown in the figure) and is used to blow clean gas on people or goods entering the clean room to remove the dust particles attached to the surface of people or goods, so as to achieve the purpose of preliminary cleaning. The direct insertion type air shower nozzle 100 includes: a basin frame 1, a blowing nozzle 2 and a clamping member. The basin frame 1 is generally in a disk shape. The top of the basin frame 1 has an air inlet a, and the end far from the top is a basin opening b. The basin opening b forms an outer edge 11 of the basin frame 1 in a direction away from the axis. The blowing nozzle 2 has a bowl-shaped air gathering part 21. The bottom of the air gathering part 21 is open to form an air outlet c. The air inlet end d of the air gathering part 21 is connected to the air inlet a of the basin frame 1, and the air outlet c extends into the basin frame 1. Specifically, the inner surface of the air gathering part 21 gradually decreases in diameter from the air inlet end d to the air outlet c. Specifically, the air gathering part 21 may have a hemispherical inner surface or a conical inner surface, and no specific limitation is made here. The clamping member is arranged on one side of the outer edge 11 of the basin frame 1 close to the air inlet a. The basin frame 1 can be snapped into and rotatably arranged on the mounting hole wall 4 of the air shower room through the clamping member. Specifically, in this embodiment, four clamping members are arranged in an array on one side of the outer edge 11 of the basin frame 1 close to the air inlet a. Of course, in other embodiments, the clamping member may also be one, two, three, five, or more. When it is one, the clamping member may be a whole circle structure. No specific limitation is made here. The basin frame 1 being rotatably arranged on the mounting hole wall 4 of the air shower room means that after assembly, the basin frame 1 can rotate relative to the mounting hole o of the mounting hole wall 4, that is, the mounting hole o can be used as a shaft hole. Specifically, the basin frame 1, the blowing nozzle 2 and the clamping member can be manufactured by stamping metal or injection molding plastic, and no specific limitation is made here.

[0049] Since a clamping member is disposed on the outer edge 11 of the basin frame 1 of the plug-in air shower nozzle 100 close to the air inlet a side, and the basin frame 1 can be clamped and rotatably disposed on the mounting hole wall 4 of the air shower room through the clamping member. Therefore, compared with the prior art that requires tapping multiple threaded holes and screwing multiple screws for fixed assembly, it has the advantage of convenient assembly.

[0050] In addition, since the air inlet end d of the air concentrating part 21 of the blowing nozzle 2 is connected to the air inlet a of the basin frame 1, the rear cover and the elastic washer in the prior art are omitted. Therefore, it has the advantages of simple structure and low manufacturing cost. In addition, after assembly, the plug-in air shower nozzle 100 can rotate relative to the mounting hole wall 4 of the air shower room. Thus, as long as there is a certain angle between the axis of the air outlet c of the blowing nozzle 2 and the axis of the basin frame 1, when the plug-in air shower nozzle 100 is rotated as a whole, the blowing angle of the plug-in air shower nozzle 100 can also be adjusted.

[0051] Optionally, please refer to Figure 2 and Figure 3 , in this embodiment, the clamping member is an elastic clamping member. The elastic clamping member is four elastic pieces 3 arranged in an array on the outer edge 11 of the basin frame 1 close to the air inlet a side; the elastic pieces 3 can radially contract when the basin frame 1 is clamped into the mounting hole o of the air shower room and can radially expand after being clamped, and the mounting hole wall 4 of the air shower room is clamped between the elastic pieces 3 and the outer edge 11 of the basin frame 1. Thus, the basin frame 1 is clamped on the mounting hole wall 4 of the air shower room through the elastic clamping member, and after assembly, the basin frame 1 can rotate relative to the mounting hole wall 4 of the air shower room. Of course, in other embodiments, the number of the elastic pieces 3 can also be one, two, three, five or more, and no specific limitation is made.

[0052] Specifically, please refer to Figure 2 , Figure 5 and Figure 6, in this embodiment, the elastic piece 3 includes a connecting section 31, a supporting section 32, a cantilever section 33, and an abutting section 34 connected in sequence. Among them, the connecting section 31 is connected to the outer edge 11 of the speaker frame 1. Optionally, the connecting section 31 can be connected to the outer edge 11 of the speaker frame 1 by welding, bonding, or through fasteners. The supporting section 32 is connected to the connecting section 31 and extends away from the outer edge 11 of the speaker frame 1; specifically, the supporting section 32 can be vertically arranged relative to the outer edge 11 of the speaker frame 1. Of course, it can also have a certain inclination angle, which is not limited here. The cantilever section 33 is connected to one end of the supporting section 32 away from the connecting section 31, and extends toward the installation hole wall 4 of the air shower room and away from the axis of the speaker frame 1. That is, from the connection end of the cantilever section 33 and the supporting section 32 to the direction of the air shower room, the distance between the cantilever section 33 and the supporting section 32 gradually increases, that is, the cantilever section 33 is suspended above the supporting section 32. The abutting section 34 is connected to one end of the cantilever section 33 away from the supporting section 32 and bends inward to abut against the installation hole wall 4 of the air shower room. Overall, the supporting section 32, the cantilever section 33, and the abutting section 34 of the elastic piece 3 form an unclosed triangular flag shape. Specifically, the elastic piece 3 can be formed by bending a metal sheet to form the connecting section 31, the supporting section 32, the cantilever section 33, and the abutting section 34. Of course, it can also be formed by plastic injection to form the connecting section 31, the supporting section 32, the cantilever section 33, and the abutting section 34, which is not specifically limited. In some embodiments, the connecting section 31 of the elastic piece 3 is fixedly configured with the outer edge 11 of the speaker frame 1 by welding.

[0053] To improve the sealing performance between the direct-insert type air shower nozzle 100 and the installation hole wall 4 of the air shower room, optionally, in this embodiment, a sealing ring (not shown in the figure) is further provided on the side of the outer edge 11 of the speaker frame 1 close to the air inlet a. In this way, after the snap-fit assembly, the sealing ring can be clamped between the outer edge 11 of the speaker frame 1 and the installation hole wall 4 of the air shower room.

[0054] Optionally, in some other embodiments, the elastic snap-fit member is a C-shaped open elastic piece ring (not shown in the figure) arranged on the side of the outer edge 11 of the speaker frame 1 close to the air inlet a, and the open elastic piece ring is coaxially arranged with the speaker frame 1. In this way, when the two free ends of the open elastic piece ring drive the whole to be radially contracted when the speaker frame 1 is inserted into the installation hole o of the air shower room and can be radially expanded after being inserted, and the installation hole wall 4 of the air shower room is clamped between the open elastic piece ring and the outer edge 11 of the speaker frame 1. In this way, the speaker frame 1 is snap-fitted on the installation hole wall 4 of the air shower room through the elastic snap-fit member, and after assembly, the speaker frame 1 can rotate relative to the installation hole wall 4 of the air shower room. Specifically, part of the open elastic piece ring is connected to the outer edge 11 of the speaker frame 1 through a connecting piece. In this way, its two free ends on both sides are suspended on the outer edge 11 of the speaker frame 1 to achieve radial contraction or expansion.

[0055] Optionally, in other embodiments, the elastic clamping member is a plurality of locking tongues (not shown in the figure) arranged in an array on the outer edge 11 of the basin frame 1 near the air inlet a and capable of radial telescopic movement along the basin frame 1. The specific structure of the locking tongue may include a baffle (not shown in the figure) arranged vertically on the outer edge 11 of the basin frame 1, a locking tongue (not shown in the figure) arranged horizontally and similar to a door lock tongue, and a compression spring (not shown in the figure) with one end abutting against the locking tongue and the other end abutting against the baffle, and a fixing sleeve (not shown in the figure) that limits the locking tongue and the compression spring and only allows the locking tongue to perform linear telescopic movement. In this way, the basin frame 1 can be clamped on the mounting hole wall 4 of the air shower room by the elastic clamping member, and after assembly, the basin frame 1 can be rotated relative to the mounting hole wall 4 of the air shower room.

[0056] Optionally, see Figure 2 In this embodiment, the basin frame 1 and the blowing nozzle 2 are integrally formed. The basin frame 1 and the blowing nozzle 2 do not need to be connected by other components, which can reduce the manufacturing cost of the plug-in air shower nozzle 100 and reduce the assembly process.

[0057] In order to make the air output of the plug-in air shower nozzle 100 more concentrated and improve the wind force, optionally, please refer to Figure 4 In this embodiment, the air outlet c of the air collecting portion 21 is a tubular air outlet 22 extending into the basin frame 1. The specific shape of the air outlet 22 can be a round tube, a flat-mouthed tube, or some other shapes, which are not specifically limited.

[0058] In order to achieve that when the basin frame 1 is rotated, the blowing angle of the plug-in air shower nozzle 100 can be relatively adjusted to adjust the air outlet direction of the plug-in air shower nozzle 100. Optionally, please refer to Figure 9 In this embodiment, a certain angle α can be set between the axis of the air outlet c of the blowing nozzle 2 and the axis of the basin frame 1, so that the air outlet direction of the plug-in air shower nozzle 100 can be adjusted by rotating the basin frame 1. Preferably, the angle α between the axis of the air outlet c of the blowing nozzle 2 and the axis of the basin frame 1 is 0° to 60°. Specifically, the angle α can be selected as 0°, 10°, 20°, 30°, 40°, 45°, 50°, 60°, as long as it is between 0° and 60°.

[0059] Another aspect of the embodiment of the utility model provides an air shower room (not shown in the figure), including an air shower room body (not shown in the figure), the air shower room body is provided with a fan (not shown in the figure), an air filter (not shown in the figure) connected to the air inlet end of the fan, a mounting hole wall 4 having a plurality of mounting holes o, and a plug-in air shower nozzle 100 as described above that can be inserted into the mounting holes o of the mounting hole wall 4. Since the air shower room has all the structures and connection relationships of the plug-in air shower nozzle 100, it has all the advantages of the plug-in air shower nozzle 100, which will not be described in detail here.

[0060] Embodiment 2

[0061] Please refer to Figure 10 and Figure 11 , this embodiment is basically the same as the first embodiment, and the difference lies only in the specific structure of the clamping member. In this embodiment, the clamping member is a plurality of clamping protrusion components 5 arranged on the periphery 13 of the basin wall of the basin frame 1. A plurality of clamping protrusion components 5 are arranged in an array on the periphery 13 of the basin wall. Specifically, the clamping protrusion component is composed of three clamping protrusions 51 with inclined slopes. A rotating groove 6 is formed between the clamping protrusion 51 near the outer edge 11 of the basin frame 1 and the outer edge 11, so that the plug-in air shower nozzle 100 can rotate relative to the mounting hole wall 4.
