[0018] The present application will be further described in detail below with reference to the accompanying drawings.

[0019] This application discloses a headstock base, referring to... Figure 1 and Figure 3 The head unit base includes a frame 1 and a connecting component 2 set on the frame 1 and used to connect the head unit. The frame 1 is provided with an air inlet channel 3 for airflow to pass through. The head unit base is provided with an arc-shaped guide surface 4 on the airflow path. The arc-shaped guide surface 4 increases the cross-sectional area of ​​the airflow on the flow path, reduces obstruction, and reduces noise.

[0020] In this embodiment, the frame 1 includes a first panel 11, a first side panel 12, a second panel 13, and a second side panel 14 connected in sequence. The end of the second side panel 14 away from the second panel 13 is connected to the end of the first panel 11 away from the first side panel 12. The first panel 11 and the second panel 13 extend in the length direction and are preferably arranged in parallel. The first side panel 12 is connected between one end of the first panel 11 and one end of the second panel 13, and the second side panel 14 is connected between the other end of the first panel 11 and the other end of the second panel 13. The first side panel 12 and the second side panel 14 extend in the width direction and are preferably arranged in parallel.

[0021] Reference Figure 1 and Figure 2 The first panel 11, the first side panel 12, the second panel 13, and the second side panel 14 extend in the height direction and together form a hollow cuboid. The air inlet channel 3 includes an air inlet 31 located at the top of the frame 1, an air outlet 33 located at the bottom of the frame 1, and a transition cavity 32 located inside the frame 1 and connecting the air inlet 31 and the air outlet 33.

[0022] In this embodiment, the first panel 11 is located on the front side relative to the second panel 13. The front side is the side of the integrated stove that the user is on when using the integrated stove. The air inlet 31 of the integrated stove faces the front side. The first panel 11 is closer to the inlet of the fan 6 inside the integrated stove than the second panel 13. At least a part of the first panel 11 is bent towards the side away from the air inlet channel 3 and formed into an arc-shaped guide surface 4. This allows the airflow to enter the transition cavity 32 from the air inlet 31 under the action of the fan 6 inside the integrated stove, and then follow the arc-shaped guide surface 4. The path is smoother and the noise is lower. The airflow then flows out from the air outlet 33. The airflow changes direction more smoothly in the flow path due to the arc-shaped guide surface 4, eliminating turbulence noise. This is different from the structure in the prior art where the first panel 11 is vertically connected to the integrated stove body 7, causing the airflow to make a right-angle turn.

[0023] In other embodiments, the arc-shaped guide surface 4 may also be provided on the side of the second panel 13 facing the air inlet channel 3, or on the side of the first side plate 12 and the second side plate 14 facing the air inlet channel 3. In some embodiments, the arc-shaped guide surface 4 may be provided on any two, any three, or any four of the first panel 11, the first side plate 12, the second panel 13, and the second side plate 14.

[0024] The cross-sectional shape of the arc-shaped guide surface 4 in the height direction can be a circular arc, an elliptical arc, a parabolic arc, etc. In some embodiments, the arc-shaped guide surface 4 can also be a combination of the above different shapes.

[0025] In this embodiment, the first panel 11 includes an arc-shaped main panel 111 and transition plates 112 respectively connected to both ends of the main panel 111. One transition plate 112 is connected to the first side panel 12, and the other transition plate 112 is connected to the second side panel 14. The shape of the transition plate 112 is determined according to the length of the main panel 111. The transition plate 112 can be an L-shaped plate in this embodiment. If the length of the main panel 111 is the same as the length of the second panel 13, the transition plate 112 can also be a plate extending in the width direction.

[0026] In some embodiments, the first panel 11 may further include a straight plate extending along the height direction or inclined to the height direction, the straight plate being tangentially connected to the upper end of the main panel 111.

[0027] In some embodiments, the first panel 11 is arc-shaped only on the inner side of the air inlet channel 3, and L-shaped or outwardly protruding arc on the outer side of the air inlet channel 3.

[0028] Because the main panel 111 is bent toward the side away from the air inlet channel 3, and the upper end is closer to the second panel 13 than the lower end, the air inlet channel 3 has a gradually expanding cross-sectional structure in the airflow path, which further reduces the air inlet resistance and increases the air inlet flow of the fan 6.

[0029] In this embodiment, a support panel 1111 is provided at the bottom end of the arc-shaped guide surface 4 of the main panel 111. The support panel 1111 is tangent to the main panel 111 and is horizontal. The support panel 1111 is used to abut or connect with the body 7 of the integrated stove. In other embodiments, the support panel 1111 may also be tangent to the top of the main panel 111.

[0030] In order to better fix the base of the motor head and the body 7 of the integrated stove, the transition plate 112 and / or the main panel 111 are provided with connection holes 113, and the base of the motor head is fixed by fasteners passing through the connection holes 113.

[0031] In order to better fix the base of the motor head and the body 7 of the integrated stove, and to ensure that the base of the motor head remains stable at both ends in the length direction after it is fixed, the bottom edge of the transition plate 112 is formed with a connecting surface 1121, and a connecting hole 113 is provided on the connecting surface 1121. The base of the motor head is fixed by fasteners passing through the connecting hole 113.

[0032] The connecting assembly 2 includes a connecting bracket 21 that is connected to the first side plate 12 and the second side plate 14 respectively. The connecting bracket 21 extends along the height direction and extends upward out of the air inlet channel 3.

[0033] Reference Figure 2This application also discloses a head unit, including a head unit base and a head unit body 5 as described in the above technical solution. The head unit body 5 has an inlet for drawing in airflow near its upper end. The lower end of the head unit body 5 is fixed to the head unit base via a connecting bracket 21. The airflow enters from the inlet of the head unit body 5 and flows into the air inlet channel 3 of the head unit base.

[0034] Reference Figure 3 This application also discloses an integrated stove, including a fan head as described in the above technical solution and a fan 6 located inside the integrated stove. The inlet of the fan 6 faces forward, and the airflow turns forward and then downward after passing through the air inlet channel 3 before entering the fan 6. In this embodiment, the arc-shaped guide surface 4 can avoid right-angle turns in the path of the airflow turning forward, thereby reducing air inlet resistance and eliminating turbulence noise.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
