The present utility model proposes a blower body 100. A hair dryer is an electrical appliance for generating an air flow to achieve hair drying and styling. The blower body 100 is a member for forming an air outlet and a target air flow.

In the embodiment of the present utility model, referring to fig. 1 to 3, the blower body 100 includes a housing 10, a main control board 20, and a rear cover assembly 30; the main control board 20 is arranged in the shell 10, the shell 10 is provided with an overhaul window 13 corresponding to the main control board 20, one side of the shell 10 provided with the overhaul window 13 is enclosed with the main control board 20 to form a containing cavity 14 communicated with the overhaul window 13, and the rear cover assembly 30 is detachably embedded in the containing cavity 14 from the overhaul window 13; the back cover assembly 30 includes an operating member 31 within the housing 10, the operating member 31 being adapted for an external tool or hand to engage and disengage the back cover assembly 30.

The purpose of providing the access window 13 corresponding to the main control board 20 is to facilitate the access to the main control board 20 after the rear cover assembly 30 is disassembled. The access windows 13 may be formed at both ends of the housing 10 or may be formed in a side wall of the housing 10.

The shell 10 and the main control board 20 enclose a containing cavity 14, and the containing cavity 14 is communicated with the overhaul window 13. The receiving chamber 14 serves to receive the rear cover assembly 30. The rear cover assembly 30 is integrally embedded in the accommodating cavity 14, so that the space in the shell 10 is fully utilized, the whole volume of the body 100 is smaller, and the portable rear cover assembly is convenient to carry. In addition, the integral insertion of the rear cover assembly 30 into the receiving chamber 14 conceals the connection seam between the rear cover assembly 30 and the housing 10, as compared to a general blower, so that the body 100 is more aesthetically pleasing. The rear cover assembly 30 may be detachably inserted into the receiving cavity 14 in various manners, such as being clamped to the housing 10 along a normal direction of the access window 13, being magnetically connected to the housing 10 along the normal direction of the access window 13, or being rotatably connected to the housing 10 around the normal direction of the access window 13.

Since the rear cover assembly 30 is integrally inserted into the receiving chamber 14, one cannot separate it from the housing 10 by grasping the rear cover assembly 30. In this embodiment, the operating member 31 located in the accommodating chamber 14 can help solve this problem. The rear cover assembly 30 embedded in the housing 10 can be separated from the housing 10 by directly acting on the operating member 31 by using an external tool or a hand, and the rear cover assembly 30 is taken out from the inspection window 13, so that subsequent inspection is facilitated. The operating member 31 may be a hand-held part or a part that is used only with a professional jig. The former facilitates opening the rear cover assembly 30 for servicing; the latter also has the function of protecting the electrical components inside the housing 10. Since the electrical components in the blower 200 are elaborate and the general consumer does not have a maintenance capability, the electrical components in the blower 200 may be damaged after the rear cover assembly 30 is easily opened, which is inconvenient for subsequent maintenance. The operation member 31 is used in combination with the professional jig to separate the rear cover assembly 30 from the housing 10 and prevent damage to the blower 200 caused by the non-professional person easily opening the rear cover assembly 30.

According to the air blowing body 100, the shell 10 is provided with the overhaul window 13 corresponding to the main control board 20, so that overhaul personnel can conveniently overhaul the main control board 20 directly through the overhaul window 13. And the body 100 is enclosed with the main control board 20 through the shell 10 to form a containing cavity 14 communicated with the access window 13, and the operating piece 31 in the rear cover assembly 30 is positioned in the containing cavity 14. The operating member 31 is adapted to be engaged by an external tool or hand to facilitate separation of the rear cover assembly 30 from the housing 10 by an attendant. The rear cover assembly 30 including the operating member 31 is completely inserted into the receiving chamber 14, and the housing 10 covers the outer circumferential surface of the rear cover assembly 30. Thus, the space in the body 100 is fully utilized, so that the body 100 is small in size and convenient to carry. And the connection seam of the case 10 and the rear cover assembly 30 is not exposed, so that the blower body 100 is more beautiful.

In an embodiment, referring to fig. 1 and 5, the back cover assembly 30 is detachably and rotatably connected to the housing 10 about a normal direction of the access window 13, and the operating member 31 is exposed to the housing 10 through the access window 13.

The rear cover assembly 30 is rotatably coupled to the housing 10 clockwise around a normal direction of the access window 13, and is rotatably separated from the housing 10 counterclockwise to the right. And vice versa. As described above, the back cover assembly 30 may be attached to the housing 10 in a variety of ways. However, compared with other disassembly and assembly methods, in this embodiment, the rear cover assembly 30 is detachably and rotatably connected to the housing 10 around the normal direction of the access window 13, and compared with the magnetic connection method of the rear cover assembly 30 and the housing 10, the connection is more firm and is less prone to loosening.

Compared with the way that the rear cover assembly 30 is clamped to the housing 10 along the normal direction of the access window 13, when the rear cover assembly 30 is disassembled, the rear cover assembly 30 is clamped to the housing 10 along the normal direction of the access window 13, and the rear cover assembly 30 or the housing 10 needs to be forced to deform so as to facilitate the separation of the rear cover assembly 30 from the housing 10. In this way, the force applied by the force applying device is difficult to grasp, and the rear cover assembly 30 or the housing 10 is easily damaged due to the fact that the rear cover assembly 30 or the housing 10 exceeds the deformation range. In the present embodiment, the back cover assembly 30 is rotatably separated from the housing 10 around the normal direction of the access window 13, and only the back cover assembly 30 is required to rotate relative to the housing 10 by applying force. The latter has higher resolution efficiency and less damage to the rear cover assembly 30 or the case 10 than the former. There are various ways of rotating connection, such as threads, snap-fit.

The operating member 31 is exposed to the housing 10 through the access window 13 such that an operator can conveniently act on the operating member 31 through the access window 13.

Further, referring to fig. 2 to 5, the rear cover assembly 30 further includes a cover main body 33, the cover main body 33 is detachably rotatably covered on the access window 13 around a normal direction of the access window 13, and the housing 10 covers an outer circumferential surface of the cover main body 33; the cover main body 33 is recessed towards the main control board 20, and the operating member 31 is fixedly connected to one side of the cover main body 33 away from the main control board 20 and is positioned in the recess of the cover main body 33, so that the operating member 31 is positioned at the inner side of the overhaul window 13; an operation space 34 for an external tool or hand to operate is formed on the operation piece 31 or between the operation piece 31 and the cover main body 33.

The cover body 33 can be detachably rotatably covered on the access window 13 around the normal direction of the access window 13 in various ways, such as a snap-fit, a screw-thread. Optionally, the cover body 33 and the housing 10 have a first snap fit and a second snap fit, respectively. One of the first clamping matching piece and the second clamping matching piece is a rotary lug, the rotary lugs comprise clamping grooves which are opened towards the same side, and the other clamping groove is a clamping strip corresponding to the clamping groove; one side of the at least one clamping groove, which is away from the opening, is provided with a first clamping protrusion; one side of the clamping strip corresponding to the clamping groove is provided with a first clamping groove; the locking strip rotates from the opening to the first locking groove to be locked with the first locking protrusion, so that the cover main body 33 is locked with the housing 10.

Since the rear cover assembly 30 is embedded in the case 10, the rear cover assembly 30 cannot be separated from the case 10 by gripping the peripheral edge of the rear cover assembly 30 and screwing the rear cover assembly 30. In this embodiment, an external tool or hand acts on the operating member 31 in the operating space 34, so that the operating member 31 rotates relative to the housing 10. Since the operating member 31 is fixedly coupled to the cover main body 33, the cover main body 33 rotates when the operating member 31 rotates relative to the housing 10.

The operating member 31 is fixedly connected to a side of the cover main body 33 facing away from the main control board 20, and is located in a recess of the cover main body 33. On the one hand, the main control board 20 can be protected before the cover main body 33 is separated from the shell 10, so that the main control board 20 is prevented from being damaged when an external tool acts on the operation piece 31; on the other hand, the operating element 31 is positioned inside the access window 13, and the space in the accommodating chamber 14 is saved. Further, the depression of the cover main body 33 also enables the formation of the operation space 34 between the operation piece 31 and the cover main body 33 to be larger.

The operation space 34 may be configured to accommodate only an external tool, or may be configured to accommodate the hand-screw operation member 31. A hand or external tool is placed in the operating space 34 and acts on the operating member 31 to rotate the operating member 31 relative to the housing 10 and thus the rear cover assembly 30.

Further, referring to fig. 3 to 6, the operation member 31 is a light guide cover 32, and the light guide cover 32 is fixedly connected to a side of the cover main body 33 facing away from the main control board 20 and is located in a recess of the cover main body 33; the light guide 32 is at least partially made of a light transmissive material such that light passes through the light guide 32 and out through the access window 13.

In the present embodiment, the operation member 31 is a light guide cover 32, so that the operation member 31 has a dual function, and can be used as an external tool or a hand-operated member and can guide light. The light guide cover 32 is fully utilized as an operation member, the number of parts is reduced, the space in the accommodating cavity 14 is saved, and the operation space 34 formed between the light guide cover 32 and the cover main body 33 is larger.

The light guide 32 may be made entirely of a light-transmitting material or may be made only partially of a light-transmitting material. Since the light guide 32 is located inside the housing 10, a part of the light guide 32 may be blocked by other parts, and thus the blocked area may not be made of a light-transmitting material. In connection with the embodiment below with cover plate 35, the side of light guide 32 facing access window 13 is shielded by cover plate 35, so that only the side walls of light guide 32 can be made of a light-transmitting material. The light passes through the light guide 32, passes through the light transmission channel 352, and exits the access window 13 to form an annular aperture. Therefore, the light guide effect can be achieved, materials can be saved, and the production cost is saved.

Further, referring to fig. 3 to 6, a side surface of the light guide cover 32 facing away from the main control board 20 is recessed toward the main control board 20 to form an operation space 34; the light guide cover 32 has an operation portion 322 arranged in the rotation direction of the cover main body 33, and the operation portion 322 is located in the operation space 34.

When the operation space 34 is formed on the outer peripheral wall of the light guide cover 32, the operation space 34 is doubly limited by the light guide cover 32 and the cover main body 33. If the concave curvature of the cover main body 33 is insufficient, the operation space 34 is small, so that an external tool or hand cannot be placed in the operation space 34 and act on the operation portion 322. In the present embodiment, the operation space 34 formed by recessing the side of the light guide cover 32 facing away from the main control board 20 is only determined by the light guide cover 32 itself. In the production and manufacturing process, only the specification of the light guide cover 32 is considered, and the influence of the cover main body 33 on the operation space 34 is not considered. Thus simplifying the production procedure and saving the production cost.

Further, referring to fig. 6, the light guide cover 32 has at least one operation portion 322, and the operation portion 322 includes two operation grooves 3221 and one bump 3222, and the two operation grooves 3221 are respectively opened at two sides of the bump 3222 along the rotation direction of the cover main body 33.

The light guide 32 has one or more operating portions 322 thereon. The two operation grooves 3221 of the operation portion are respectively opened at both sides of the bump 3222, and provide conditions under which an external tool can firmly control the light guide cover 32. The external tool can control the rotation of the light guide cover 32 with respect to the cover main body 33 through the operation portion 322, and finally separate the cover main body 33 from the housing 10. When the tool is detached, the tool is inserted into the two operation grooves 3221 to clamp the protrusions 3222, so that the light guide cover 32 is rotated relative to the housing 10, and the cover main body 33 is rotated until the cover main body 33 is separated from the housing 10.

Further, referring to fig. 3 to 7, the rear cover assembly 30 further includes a cover plate 35, the cover plate 35 is positioned at the recess of the cover main body 33, the area of the cover plate 35 is smaller than the area of the access window 13, and a light-transmitting channel 352 is formed between the cover plate 35 and the cover main body 33; the cover 35 is detachably and fixedly connected to the light guide cover 32, and covers the operation space 34.

The cover plate 35 covers the operation space 34, and on the one hand, may modify the appearance of the blower 200, and on the other hand, may shield part of dust. The area of the cover plate 35 is smaller than that of the access window 13, and a light-transmitting channel is formed between the cover plate 35 and the cover main body 33. The light passes through the light guide 32 and then through the light transmission channel 352 and finally out the access window 13. The cover plate 35 is detachably and fixedly connected with the light guide cover 32, so that dust and dirt in the cover main body 33 can be cleaned conveniently. The cover 35 may be removably secured to the light guide 32 in a variety of ways, such as by clamping, magnetic attraction, threading, etc.

Further, referring to fig. 6 and 7, the operation space 34 has a first mounting portion 341 therein, the first mounting portion 341 being spaced apart from the operation portion 322 in the rotation direction of the cover main body 33; the cover 35 is provided with a second mounting portion 351 engaged with the first mounting portion 341.

The first mounting portion 341 and the operation portion 322 are provided in the operation space 34, so that the operation space 34 can be effectively utilized. When the cover plate 35 is fixedly coupled to the cover main body 33, the first mounting portion 341 is coupled to the second mounting portion 351. When the cover main body 33 is to be separated from the housing 10, an external tool or a hand acts on the operation portion 322 to rotate the cover main body 33 with respect to the housing 10.

The first and second mounting portions 341 and 351 have various forms. For example, one of the first mounting portion 341 and the second mounting portion 351 is a mounting protruding strip, and the other is a sliding groove. The mounting convex strip is sunken towards one side of the wall surface of the sliding groove to form a second clamping groove. The sliding grooves all form openings towards the same side, and one side of the sliding grooves far away from the openings is provided with a second clamping protrusion. The mounting protruding strip rotates from the opening to the second clamping groove to be clamped with the second clamping protrusion so that the first mounting portion 341 and the second mounting portion 351 are connected.

In one embodiment, referring to fig. 3 to 7, the cover plate 35 is rotatably and detachably fixedly connected to the light guide cover 32; the rotation direction of the cover plate 35 rotationally fixed to the light guide cover 32 coincides with the rotation direction of the cover main body 33 rotationally fixed to the housing 10.

If the rotation direction of the cover plate 35 fixed to the light guide cover 32 is not identical to the rotation direction of the cover main body 33 fixed to the housing 10, when a force in a rotation direction is applied to the cover plate 35 so that it is mounted to the light guide cover 32, the cover main body 33 is rotated relative to the housing 10 in a direction opposite to the rotation direction, so that the cover main body 33 and the housing 10 are separated. In the present embodiment, the rotation direction of the cover plate 35 fixed to the light guide cover 32 coincides with the rotation direction of the cover main body 33 fixed to the housing 10. A force in a rotation direction is applied to the cover plate 35 so that when it is mounted to the light guide cover 32, the cover main body 33 rotates with respect to the housing 10 in the same direction as the rotation direction. This can make the cover main body 33 more firmly fixed to the case 10.

In an embodiment, referring to fig. 1 to 5, the housing 10 is cylindrical, and an opening of one end of the housing 10 in the axial direction forms an inspection window 13; the rear cover assembly 30 is detachably inserted into the accommodating chamber 14 in the axial direction of the housing 10, and the housing 10 covers the outer circumferential surface of the rear cover assembly 30.

The casing 10 is cylindrical, and the access window 13 and the main control board 20 are circular. This facilitates installation. Compared with the side wall of the shell 10, the overhaul window 13 formed by the opening of one end of the shell 10 along the axial direction does not influence the air outlet of the blower. Since the housing 10 is cylindrical, the rear cover assembly 30 is assembled and disassembled along the axial direction of the housing 10, and only the rear cover assembly 30 is required to be rotated in alignment with the access window 13. There is no need to constantly adjust the installation angle at the time of installation to align the rear cover assembly 30 with the access window 13. The rear cover assembly 30 is attached to and detached from the housing 10 in the axial direction of the housing 10 with higher assembly efficiency than in other attachment and detachment directions.

In one embodiment, referring to fig. 2, 4 and 5, the housing 10 includes an inner housing 11 and an outer housing 12, the inner housing 11 being embedded in the outer housing 12; the rear cover assembly 30 is clamped with the inner shell 11, and the rear cover assembly 30 is abutted against the end face of one side of the inner shell 11 provided with the overhaul window 13; the outer case 12 covers the outer circumferential surfaces of the inner case 11 and the rear cover assembly 30.

The rear cover assembly 30 abuts against the end surface of the side of the inner case 11 where the access window 13 is opened. The end surface of the inner shell 12 plays a limiting role, so that the rear cover assembly 30 is prevented from being excessively extended into the accommodating cavity 14 to damage the main control board 20. The outer case 12 is covered on the outer circumferential surfaces of the inner case 11 and the rear cover assembly 30 such that the rear cover assembly 30 is integrally embedded in the outer case 12 while increasing the wall thickness of the case 10 to enhance the anti-falling performance. In addition, the abutting portion of the inner case 11 and the rear cover assembly 30 may be shielded, so that the body of the blower 200 is more beautiful.

The inner shell 11 and the outer shell 12 may be both made of plastic or metal, or the inner shell 11 may be made of plastic and the outer shell 12 may be made of metal.
