Example 1

Referring to fig. 1, the present embodiment provides a blower housing assembly 10, which is suitable for mounting a functional device to achieve a blowing effect. Conventionally, an airflow generating assembly and a heating assembly are disposed in the blower housing assembly 10, and the airflow generating assembly can generate a negative pressure, so that external fluid enters the blower housing assembly 10 under the action of the negative pressure and flows to the outside of the blower housing assembly 10. Meanwhile, the heating assembly arranged in the blowing shell assembly 10 can also heat the flowing fluid, and the heated fluid can accelerate the drying or heating of the target object after being blown to the target object, so that the drying or heating efficiency is improved. In this embodiment, the fluid refers to the air flow.

Wherein the airflow generation assembly comprises a fan which operates to generate negative pressure. Alternatively, the airflow generating assembly includes a motor and an impeller connected to a driving shaft of the motor, and the motor operates to drive the impeller to rotate so as to generate the negative pressure. And the heating assembly includes a heating wire annularly disposed to uniformly heat the fluid.

In order to increase the blowing function, a water ion generator or an essential oil assembly may be further disposed in the blowing housing assembly 10, the water ion generator may generate water ions, and the water ions may flow to the target object along with the fluid; or the volatile matter of the essential oil component can flow to the target object along with the fluid, so that the target object is nourished, and the target object is prevented from being dried and the like, so that different user requirements and different use scenes are met.

Referring to fig. 1, 2 and 4, in detail, the blowing casing assembly 10 includes a wind barrel casing 2 and a handle casing 1 connected to the wind barrel casing 2. The air duct housing 2 has a connection port 23 and an air outlet 21 connected to the connection port 23, the handle housing 1 has an air inlet 13 connected to the connection port 23, the airflow generating assembly is disposed in the handle housing 1, and the heating assembly is disposed in the air duct housing 2, so that the fluid enters the handle housing 1 from the air inlet 13 and flows to the air outlet 21 through the connection port 23 (the direction indicated by arrow a in fig. 5).

The handle housing 1 and the air duct housing 2 may be made of polycarbonate (PC plastic) which has flame retardancy and oxidation resistance. The flame retardance of the manufacturing material can reduce the possibility of overall combustion when functional devices and circuits in the handle shell 1 and the air duct shell 2 burn in an aging mode. The oxidation resistance of the manufacturing material can ensure that the handle shell 1 and the air duct shell 2 can keep the color brightness and the like so as to ensure the integral aesthetic property.

In other embodiments, the handle housing 1 and the wind barrel housing 2 can be made of other materials, such as light metal, which has certain hardness and good flame retardancy. Meanwhile, in order to improve the oxidation resistance of the light metal, a coating or the like may be coated on the surface thereof, which is not particularly limited herein, depending on the actual situation.

In some related arts, the air duct housing 2 and the handle housing 1 are usually configured to be detachably connected, and the detachable manner may be a threaded connection, a snap connection, or the like. However, the detachable connection manner may cause unstable connection between the air duct housing 2 and the handle housing 1 during use, thereby resulting in poor connection stability between the air duct housing 2 and the handle housing 1. And, in order to realize the detachable connection of the air duct shell 2 and the handle shell 1, corresponding connecting mechanisms can be arranged on the air duct shell 2 and the handle shell 1. When the connecting mechanism is arranged at the outer sides of the air duct shell 2 and the handle shell 1, the whole aesthetic property is influenced. Therefore, in order to ensure the aesthetic appearance, the connecting mechanism is conventionally disposed inside the air duct housing 2 and the handle housing 1.

However, when the connection mechanism is provided inside the handle casing 1 and the blower casing 2, the inner space of the handle casing 1 and the blower casing 2 is occupied, and accordingly, the amount of fluid flowing through the handle casing 1 and the blower casing 2 is reduced accordingly. However, other components, such as circuit boards, etc., which generate heat during operation, may also be provided in the handle housing 1 and the blower housing 2. When the amount of fluid flowing through the handle housing 1 and the air cylinder housing 2 decreases, it may cause a situation where heat cannot be dissipated to the operating device in time, which in turn affects the operation of the device and reduces the service life of the device.

Referring to fig. 1, fig. 2 and fig. 4, in order to solve the above technical problem, at least a portion of the handle casing 1 in the present embodiment is fixedly connected to the air duct casing 2. In addition, in order to enhance the stability of the connection between at least part of the handle housing 1 and the air duct housing 2 and simplify the production and manufacturing process, at least part of the handle housing 1 and the air duct housing 2 are integrally formed. Namely, at least part of the handle shell 1 and the air cylinder shell 2 are directly and integrally molded in the injection molding process, and are simultaneously demolded, and fixed connection is realized through processes such as bonding and the like without respectively producing at least part of the handle shell 1 and the air cylinder shell 2.

Specifically, the handle housing 1 includes a first housing portion 11 and a second housing portion 12, and the first housing portion 11 and the second housing portion 12 cooperate to form a fluid flow channel inside the handle housing 1 for fluid to flow through. The first housing portion 11 includes a first end portion having a receiving cavity, the first end portion of the first housing portion 11 is fixedly connected to the connection port 23, and the second housing portion 12 is detachably connected to the first housing portion 11. That is, in the present embodiment, the length of the first housing portion 11 in the longitudinal direction is equal to the length of the handle housing 1, and the first housing portion 11 and the air duct housing 2 are integrally molded. The length direction of the first housing part 11 is parallel to the flow direction of the fluid in the fluid flow channel.

The first end of the first housing 11 is fixedly connected to the connection port 23, so that one end of the accommodating cavity is communicated with the connection port 23, thereby enhancing the connection stability between the handle housing 1 and the air duct housing 2. Simultaneously, because the first end and the connector 23 fixed connection of first casing portion 11, need not to be provided with extra coupling mechanism between first casing portion 11 and connector 23, can not occupy the inner space of first casing portion 11 and wind barrel casing 2, then can not influence the flow that enters into the fluidic in handle casing 1 and the wind barrel casing 2, can in time dispel the heat to the functional device of handle casing 1 and the interior operation of wind barrel casing 2, make the functional device normal operation, and the life of extension functional device.

Meanwhile, in order to further enhance the stability of the connection between the first housing portion 11 and the air duct housing 2, the orthographic projection of the first end portion of the first housing portion 11 on the air duct housing 2 always covers the connection port 23 on the flow path (the direction indicated by the arrow a in fig. 5) where the fluid flows from the air inlet 13 to the connection port 23 through the fluid flow channel. That is, the first end of the first housing portion 11 is connected to the connection port 23 of the air duct housing 2, and the inner diameter of the first end of the first housing portion 11 is greater than or equal to the size of the connection port 23, so that the first housing portion 11 can support the weight of the air duct housing 2, and when the functional device is provided in the blower housing assembly 10, the first housing portion 11 can support the total weight of the air duct housing 2 provided with the functional device, thereby ensuring the connection stability between the first housing portion 11 and the air duct housing 2.

Alternatively, the shape of the first end of the first housing part 11 matches the shape of the connection port 23. For example, when the connection port 23 is circular, the first end of the first housing part 11 is also circular; when the connection port 23 is rectangular, the first end of the first housing part 11 is also rectangular, so that when the first end of the first housing part 11 is connected to the connection port 23, the first end of the first housing part 11 and the connection port 23 are all connected because the first end of the first housing part 11 has the same shape as the connection port 23, the connection area between the first end of the first housing part 11 and the connection port 23 is increased, the connection stability between the first end of the first housing part 11 and the connection port 23 is ensured, and the connection stability between the handle housing 1 and the air cylinder housing 2 is ensured.

Referring to fig. 2 and 3, in order to further enhance the stability of the connection between the first housing part 11 and the air duct housing 2, the blower housing assembly 10 further includes first reinforcing ribs 5, and the first reinforcing ribs 5 are disposed on the outer wall of the first end portion of the first housing part 11, so that the first reinforcing ribs 5 are respectively connected to the first housing part 11 and the air duct housing 2. The first reinforcing rib 5 has a first connecting surface 51 and a second connecting surface 52, the first connecting surface 51 is connected to one side of the air duct housing 2 close to the connecting port 23, and the second connecting surface 52 is connected to one side of the first housing portion 11 close to the air duct housing 2.

In this embodiment, the first reinforcing ribs 5 are provided with two types, wherein, the fluid flowing direction in the air duct casing 2 is the front (the direction indicated by arrow a in fig. 5), the lengths of the first reinforcing ribs 5 provided at the first end portion of the first casing portion 11 and the front and rear sides of the air duct casing 2 are shorter, and the front and rear sides are provided with a plurality of first reinforcing ribs 5, the plurality of first reinforcing ribs 5 are uniformly distributed, so as to support the weight of the air duct casing 2, thereby improving the connection stability between the first end portion of the first casing portion 11 and the air duct casing 2. The first reinforcing ribs 5 provided at the first end portion of the first casing portion 11 and the left and right sides of the wind drum casing 2 are long, and one of the first reinforcing ribs 5 is provided at the left and right sides. The benefit of this arrangement is: the injection molding and demolding of the first shell part 11 and the air cylinder shell 2 are facilitated while the influence of the speed of the fluid in the air cylinder shell 2 on the stability of the connection between the first shell part 11 and the air cylinder shell 2 is prevented.

The first housing part 11 is provided with a first opening 111, the second housing part 12 is provided with a second opening 121 adapted to the first opening 111, and the second housing part 12 is detachably mounted at the first opening 111 through the second opening 121 to be detachably connected to the first housing part 11. By providing the first opening 111 on the first housing part 11 and the second opening 121 on the second housing part 12, the first housing part 11 and the second housing part 12 can be detachably connected through the first opening 111 and the second opening 121, so as to facilitate the subsequent assembly and maintenance of the functional components in the handle housing 1.

In order to ensure the stability of the connection between the first housing part 11 and the second housing part 12, after the first housing part 11 and the second housing part 12 are mounted, the first housing part 11 and the second housing part 12 are further connected by a fastener to prevent the first housing part 11 and the second housing part 12 from being separated. Threaded holes are formed in the first housing portion 11 and the second housing portion 12, and fasteners sequentially penetrate through the threaded holes in the first housing portion 11 and the second housing portion 12 to connect the first housing portion 11 and the second housing portion 12. In this embodiment, the fastener is a conventional structure such as a bolt.

Meanwhile, the first housing portion 11 and the second housing portion 12 may further be provided with a fastening structure, that is, one of the first housing portion 11 and the second housing portion 12 is provided with a fastening groove, and the other of the first housing portion 11 and the second housing portion 12 is provided with a fastening block fastened with the fastening groove, so that when the second housing portion 12 is mounted on the first housing portion 11, the fastening groove and the fastening block are fastened to fix the first housing portion 11 and the second housing portion 12 first, and then the first housing portion 11 and the second housing portion 12 are further fixed by a fastening member.

In order to enhance the sealing performance of the handle housing 1 to prevent the fluid from flowing out of the first and

second housing parts

11 and 12 from the first and

second openings

111 and 121, the blower housing assembly 10 further includes a sealing structure, which may be disposed on the first opening 111, or on the second opening 121, or on both the first and

second openings

111 and 121. The sealing structure can effectively prevent the fluid from flowing out to the accommodating space formed by the first housing part 11 and the second housing part 12, so as to ensure the fluid flow and the fluid flow speed in the accommodating space.

Taking the example that the sealing structure is disposed on the first opening 111 as an example, specifically, the sealing structure includes a sealing member 4, and the sealing member 4 is connected to the first opening 111. When the first housing part 11 and the second housing part 12 are mounted, at least part of the inner wall of the second housing part 12 abuts against the sealing member 4. Accordingly, when the sealing structure is disposed on the second opening 121, the sealing member 4 is connected to the second opening 121, and when the first housing portion 11 and the second housing portion 12 are mounted, at least a portion of the inner wall of the first housing portion 11 abuts against the sealing member 4. Similarly, when the sealing member 4 is disposed on the first opening 111 and the second opening 121 simultaneously, when the first housing part 11 and the second housing part 12 are installed, at least a portion of the inner wall of the first housing part 11 abuts against the sealing member 4, and at least a portion of the inner wall of the second housing part 12 abuts against the sealing member 4, or the sealing member 4 on the first opening 111 and the sealing member 4 on the second opening 121 abut against each other.

In this embodiment, also in order to reduce the difficulty of the manufacturing process, taking the example that the sealing member 4 is disposed on the first opening 111, the sealing member 4 is formed to protrude from the surface of the first opening 111 toward the outside. That is, in the present embodiment, the seal member 4 and the first opening 111 are integrally provided. The first housing portion 11 has a wall thickness, the thickness of the sealing member 4 is smaller than the thickness of the first housing portion 11, and the sealing member 4 is disposed at a position where the first opening 111 is close to the inner wall surface of the first housing portion 11, so that a step is formed between the sealing member 4 and the first opening 111. When the first housing part 11 and the second housing part 12 are mounted, the second housing part 12 is mounted on the step through the second opening 121, and the inner wall of the second housing part 12 abuts against the outer surface of the step, thereby achieving the sealing effect. At this time, the sealing member 4 and the first opening 111 form a seam allowance structure, that is, when the second housing part 12 is mounted on the first opening 111 of the first housing part 11 through the second opening 121, the two are connected and sealed through the seam allowance structure.

Further, in order to further enhance the sealing property between the first opening 111 and the second opening 121, the total length of the sealing member 4 is greater than or equal to the circumference of the first opening 111 or the second opening 121. The perimeter of the first opening 111 or the second opening 121 is the total length of the first opening 111 or the second opening 121 after extending in a straight line. By setting the total length of the sealing member 4 to be greater than or equal to the perimeter of the first opening 111 or the second opening 121, after the first housing part 11 and the second housing part 12 are mounted through the first opening 111 and the second opening 121, the sealing performance of the first opening 111 and the second opening 121 is enhanced to prevent the fluid from flowing out from the gap between the first opening 111 and the second opening 121.

The lengths of the first opening 111 and the second opening 121 are set according to actual conditions, so as to arrange the functional devices in the accommodating space formed by the first housing part 11 and the second housing part 12, which is not specifically limited herein and is determined according to actual conditions.

The blowing shell assembly 10 further comprises a protection shell 3, and the protection shell 3 is sleeved on the outer side of the handle shell 1 and connected with the handle shell 1. Wherein, the one end of protection casing 3 passes through the fastener with handle casing 1 and is connected, and the other end of protection casing 3 is held the butt with setting up the first strengthening rib 5 card to casing portion and 2 departments of wind barrel and is installed. At this moment, the first reinforcing rib 5 further comprises a guide surface 53, the protection shell 3 is mounted on the handle shell 1 along the guide surface 53, and the guide surface 53 is matched with one end of the protection shell 3 in shape, so that the protection shell 3 can be mounted conveniently, the protection shell 3 can be limited transversely, and relative rotation between the protection shell 3 and the handle shell 1 is avoided. In the present embodiment, the guide surface 53 has an arc shape, and accordingly, one end of the protection housing 3 has an arc shape.

When the protection housing 3 is mounted on the handle housing 1, the guide surface 53 is in interference fit with the inner wall surface of the protection housing 3, so that the first reinforcing rib 5 can reinforce and support the protection housing 3.

Please refer to fig. 3, fig. 5 and fig. 6, wherein the air duct casing 2 has a wall thickness. A groove 22 is formed at a position where the air duct housing 2 contacts the first housing part 11, the groove 22 is formed by recessing from the surface of the air duct housing 2, a mating surface 221 is formed between the bottom wall of the groove 22 and the side wall of the groove 22, the mating surface 221 may be an annular structure, and the hollow of the annular structure forms the connection port 23. As can be seen from the foregoing, the first end of the first housing portion 11 is connected to the connection port 23, accordingly, the first connection surface 51 of the first reinforcing rib 5 is connected to the first end of the first housing portion 11, and the second connection surface 52 of the first reinforcing rib 5 is connected to at least part of the mating surface 221.

The protective housing 3 has an abutting portion 31, and the abutting portion 31 is provided at an end of the protective housing 3 provided near the first end portion of the first housing portion 11. When the protective housing 3 is mounted on the handle housing 1, the abutting portion 31 is fitted to the mating surface 221. In the present embodiment, the mating surface 221 is arc-shaped, and correspondingly, the abutting portion 31 is also arc-shaped. The contact of the arc-shaped surfaces has a more stable connection mode with respect to line connection, planar connection, etc., thereby achieving a close fit between the protective housing 3 and the air cylinder housing 2.

Meanwhile, as can be seen from the foregoing, the matching surface 221 is a concave surface, and after the abutting portion 31 of the protection casing 3 and the matching surface 221 are installed, the outer surface of the abutting portion 31 and the outer surface of the air duct casing 2 are located on the same arc surface, so that the whole air duct casing assembly 10 has no additional protruding portion, and the aesthetic property of the air duct casing assembly 10 is improved.

As described above, the duct case 2 has the concave groove 22, the concave groove 22 is formed by being depressed from the surface of the duct case 2, and the hollow of the mating surface 221 forms the connection port 23. At this time, the strength at the groove 22 is poor. In order to enhance the strength of the air duct housing 2 located in the groove 22 and ensure the aesthetic property of the air duct housing 2, the air duct housing 2 further comprises a second reinforcing rib 24, and the second reinforcing rib 24 is arranged on the inner wall surface of the air duct housing 2 and is close to the connecting port 23.
