[0053] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Note that the various aspects described below with reference to the accompanying drawings and specific embodiments are merely exemplary and should not be construed as limiting the scope of protection of the present invention.

[0054] Please refer to Figures 1 to 5 The present invention provides a linked air-heating ventilator, comprising a chassis 1, a fan 2, a heating module 121, a control module and a linked switch valve group; wherein the chassis 1 is provided with an air inlet 11, a ventilation outlet 13 and a warm air outlet 12; the fan 2 is arranged in the chassis 1 near the air inlet 11; the heating module 121 is installed at the warm air outlet 12; the control module is arranged in the chassis 1, and the control module is connected to the heating module 121; and the linked switch valve group includes a lifting valve 41 and a lifting valve 41 that are linked to each other. The rotary valve 31 blocks / opens the ventilation outlet 13 by rotating; the lifting valve 41 blocks / opens the warm air outlet 12 by lifting and lowering its position. The rotary valve 31 is provided with at least one linkage slide groove 311 which opens obliquely from low to high along the rotation direction. A linkage slide key 312 is provided in the linkage slide groove 311. The linkage slide key 312 is applied with a lifting force by the linkage slide groove 311 when the rotary valve 31 rotates clockwise or counterclockwise. The linkage slide key 312 is connected to the lifting valve 41. The present invention controls the rotary valve 31 and the lifting valve 41 at the same time through the linkage switch valve group, and then controls the ventilation outlet 13 and the warm air outlet 12 at the same time, so that the two are opened and closed respectively. When the ventilation outlet 13 is opened to discharge air, the lifting valve 41 of the linkage switch valve group closes the warm air outlet; conversely, when the ventilation outlet 13 is closed, the lifting valve 41 of the linkage switch valve group opens the warm air outlet to discharge air, and can also discharge warm air through the heating module 121; or when the ventilation outlet 13 is half opened, the lifting valve 41 of the linkage switch valve group closes half of the warm air outlet to discharge air, thereby achieving the ventilation effect of the ventilation outlet 13 and the air discharge effect of the warm air outlet 12.

[0055] In this embodiment, we prefer to use a square chassis 1, the purpose of which is to make installation more convenient and the structure more regular.

[0056] As previously described, the function of the linked on / off valve assembly is to synchronously operate the rotary valve 31 and the lift valve 41, thereby achieving opposite operating effects on the warm air outlet 12 and the ventilation outlet 13. Preferably, the rotation range of the rotary valve 31 and the lift range of the lift valve 41 need to match within a certain range. The rotation range is defined as the range between fully opening the ventilation outlet 13 and just closing the ventilation outlet 13; the lift range of the lift valve 41 is defined as the range between just closing the warm air outlet 12 and just opening the warm air outlet 12. Therefore, the lift range is equal to the rotation range.

[0057] Furthermore, the linkage switch valve group also includes a driving mechanism, which facilitates the control of the linkage switch valve and avoids the disadvantages of manual operation of the linkage switch valve. However, it should be noted that the function of the linkage switch valve cannot be achieved by artificial means, so this technical solution should also be included in the predictable protection scope of this application.

[0058] Specifically, the drive mechanism includes a drive motor 32, a rotating base 35, a rotating shaft, a first tooth segment 33, and a second tooth segment 34. The rotating base 35 is mounted within the chassis 1 via the rotating shaft (not shown; the rotating shaft is mounted on the chassis and allows the rotating base to rotate about its axis). The rotary valve 31 is disposed on the rotating base 35. The first tooth segment 33 is disposed at the drive end of the drive motor 32, and the second tooth segment 34 is disposed on the rotating base and engages with the first tooth segment 33. The linkage slot 311 is formed in the sidewall of the rotating base 35. Preferably, the first tooth segment 33 is a first gear, with its drive end being the drive shaft of the drive motor 32. The first gear is mounted and fixed on the drive shaft of the drive motor 32. The second tooth segment 34 is disposed on an arc-shaped plate having the same curvature as the rotational curvature of the rotary valve 31. Rotation of the rotary valve 31 is provided by the engagement of the arc-shaped second tooth segment 34 on the arc-shaped plate. The rotating seat 35 is integrated with the arc plate, and the rotation of the rotating seat 35 is achieved by the second tooth segment 34 on the arc plate and the first gear meshing and rotating with each other.

[0059] The lift valve 41 opens and closes the warm air outlet 12 by lifting. Specifically, the lift valve 41 includes an enclosure plate 42 and a lift valve plate 41. The enclosure plate 42 encloses the lower portion of the warm air outlet 12 and forms an air cavity. The enclosure plate 42 has a control air outlet. The lift valve plate 41 is located within the air cavity and rests on the control air outlet. The linkage slide key 312 connects the lift valve plate 41 to the linkage slide key 312 via a lift connector 411, guiding the lift valve plate 41 to open / close the control air outlet. Preferably, the shape of the connector 411 is adapted to the lift valve 41. In this embodiment, it is a cylindrical plate with the lift valve 41 connected to its top.

[0060] Specifically, the function of the enclosing plate 42 is to form an air cavity with the warm air outlet 12. The air cavity is sealed on all sides by the enclosing plate 42, and only the warm air outlet 12 and the control air outlet exist. Therefore, the air outlet effect of the warm air outlet 12 can be achieved by controlling the blocking and opening of the air outlet. Furthermore, the function of the lifting valve plate 41 is to control the blocking of the control air outlet. The rotary valve 31 rotates to close the ventilation outlet 13, driving the rotation of the linkage slide 311, while the linkage slide key 312 does not rotate. The linkage slide 311 opened obliquely gives the linkage slide key 312 an upward force, causing the linkage slide key 312 to rise, thereby driving the lifting valve plate 41 to rise, and the control air outlet originally blocked by the lifting valve plate 41 is opened, and the warm air outlet 12 discharges air; the opposite principle is also true.

[0061] For ease of description, the square chassis 1 is divided into an air inlet compartment, a working compartment, and an air outlet compartment. The air inlet 11 is connected to the air inlet compartment, the fan 2 is located in the working compartment, and the ventilation outlet 13 and the warm air outlet 12 are connected to the air outlet compartment, but the air flow is controlled by the rotary valve 31 and the lifting valve 41, respectively. Specifically, the ventilation outlet 13 is located on the side of the chassis 1, and the ventilation outlet 13 and the warm air outlet 12 are located on the same side of the chassis 1. When finally installed, both face the bathroom or kitchen space.

[0062] Furthermore, in order to pass through the turbulence of the air flow or the Bernoulli effect at the air outlet, the warm air outlet 12 is set as an annular air outlet. The annular air outlet can gather the air in the direction of the inner part of the ring, gather the air through the Bernoulli effect, and increase the air flow. Furthermore, the heating module 121 is installed on the annular air outlet, and the inner circle of the annular air outlet is provided with a functional area 122. Specifically, the structure of the annular air outlet is to first open a circular opening on the chassis 1, and then set a circular functional area 122 in the circular opening. An annular air outlet is formed between the two concentric circles. The heating module 121 is installed on the annular air outlet. The heating module 121 is preferably a PTC heating module 121, which is controlled by the control module.

[0063] Furthermore, decorations, lamps or speakers are provided on the functional area 122. The purpose of this embodiment is to increase the functionality of the present technology, and can provide lighting or voice control of speakers, audio playback, etc.

[0064] As mentioned above, the air inlet 11 is an annular air inlet 11, and the inner ring 111 of the annular air inlet 11 is a circular decorative plate, lamp or speaker. Its structural principle is the same as that of the warm air outlet 12, and no redundant description is given here.

[0065] Furthermore, in order to reduce the noise caused by airflow collision, an air duct guide 21 is provided in the working compartment or the air outlet compartment of the chassis 1. The air duct guide 21 is provided with an arc-shaped guide surface facing the air outlet end of the fan 2. The main purpose is to rectify the airflow when it is blown out by the fan 2 through the arc-shaped guide surface, and the airflow blowing on the arc-shaped guide surface can reduce the collision with the surface, thereby reducing the noise caused by the collision. Furthermore, the fan 2 separates the working compartment and the air outlet compartment, making the two relatively closed. Therefore, when the airflow from the fan 2 enters the air outlet compartment, it will first fill the entire air outlet compartment and reach a balanced pressure. The pressure in the air outlet compartment is higher than the external pressure, making the air outlet compartment have the effect of a static pressure compartment, thereby achieving a more uniform air outlet for the ventilation outlet and warm air outlet installed in the air outlet compartment.

[0066] Furthermore, the airflow at the air inlet is sucked in and needs to be further combed and sorted. In this embodiment, an air inlet mesh cover 6 is provided at the air inlet 11 in the chassis 1. The air inlet mesh cover 6 is provided with uniform mesh holes for airflow dredging and noise reduction, thereby achieving the effect of reducing noise.

[0067] Furthermore, the bottom of the chassis 1 is a honeycomb structure 14 .

[0068] It should be noted that the control module is not specifically described in this embodiment because the control module is common knowledge in the field, including electrical components such as chips, integrated circuits and power supplies that provide power and control for this product, so they are not described in detail.

[0069] A person skilled in the art may make various modifications to the present invention based on the above description. Therefore, without violating the spirit of the claims of the present invention, certain details in the embodiments should not be construed as limiting the present invention, and the present invention shall be protected within the scope defined by the appended claims.
