Description

[0001] The invention relates to the technical field of air purification equipment, in particular to an air outlet device and an air disinfector. Background Art

[0002] As people's living standards improve, they have higher and higher requirements for indoor environment, and air quality is an important factor that reflects the indoor environment. An air disinfector is a device used to disinfect the air. The indoor air is disinfected by the air disinfector and then discharged into the room, which can effectively reduce harmful bacteria in the air. The air disinfector has an air inlet and an air outlet. If the air outlet faces directly upward, it is easy for foreign objects to fall into the air disinfector, affecting its normal operation and service life. For this reason, a device for changing the direction of the air outlet can be set at the air outlet of the air disinfector so that the air outlet does not face upward. However, the separately provided device is bound to hinder air circulation, reduce the air outlet flow rate, and affect the sterilization and disinfection effect of indoor air.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0033] like Figure 1 As shown, in one embodiment, an air outlet device 10 is provided, comprising an air guide tube 11, wherein the direction of the air inlet of the air guide tube 11 is not parallel to the direction of the air outlet. In other words, the air guide tube 11 can change the wind direction so that the air inlet direction is different from the air outlet direction. Figure 1 The air inlet of the air guide 11 is from bottom to top, and the air outlet of the air guide 11 is from left to right. The air inlet of the air guide 11 is used to communicate with the air outlet of the external device, so that the air outlet direction of the external device can be changed by using the air guide 11. Figure 8 As shown, the air guide 11 is arranged on the disinfection machine body 21, so as to change the original air outlet direction of the disinfection machine body 21 from facing upward to facing rightward. Moreover, the change of the air outlet direction means that the air outlet faces a different direction. The original air outlet of the disinfection machine body 21 faces upward, and foreign objects from the outside are easy to fall into the disinfection machine body 21, causing the disinfection machine body 21 to fail to operate normally, affecting its service life. After the air guide 11 is arranged, the original air outlet direction is changed, so that the final air outlet does not face upward, preventing foreign objects from falling into the disinfection machine body 21.

[0034] Furthermore, in order to improve the overall air flow rate after changing the air outlet direction, Figure 1 As shown, in one embodiment, an air outlet grille 12 is provided at the air outlet of the air guide tube 11. Figure 2 As shown, the air outlet grille 12 includes a plurality of air guide strips 121, and the plurality of air guide strips 121 are arranged at intervals along the circumference of the air outlet grille 12, one ends of the plurality of air guide strips 121 are gathered in the middle of the air outlet grille 12, and the other ends are distributed in the outer extension of the air outlet grille 12 in a divergent manner. The air outlet grille 12 includes at least two air guide areas 122, and each air guide area 122 is arranged in sequence in the circumferential direction of the air outlet grille 12, wherein each air guide strip 121 in one air guide area 122 is inclined in a clockwise direction relative to the forward projection plane of the air outlet grille 12, and each air guide strip 121 in the other air guide area 122 is inclined in a counterclockwise direction relative to the projection plane. The forward projection plane of the air outlet grille 12 here refers to Figure 2 and Figure 3 For example, if the outer frame 124 of the air outlet grille 12 is circular, the forward projection plane is a projection plane parallel to the plane where the outer frame 124 is located.

[0035] like Figure 2 and Figure 3As shown, the air outlet grille 12 includes two air guide areas 122. The air guide strips 121 of the two air guide areas 122 guide the air flow to the middle, so that the air flow blown out through the air outlet grille 12 is more concentrated and has a higher flow rate. When it is applied to the air disinfector 20, the air flow can be blown farther, speeding up the indoor air circulation, thereby improving the sterilization and disinfection effect. Moreover, based on the high air flow rate flowing out of the air outlet grille 12, the user can have a blowing experience, and the blown air is sterilized and disinfected relatively clean air.

[0036] like Figure 4 As shown, the surface of the air guide strip 121 facing the inside of the air guide cylinder 11 is the windward surface, and the surface of the air guide strip 121 facing away from the windward surface is the leeward surface 1211. The side surface of the air guide strip 121 connecting the windward surface and the leeward surface 1211 is the air guide surface 1212, and the air guide surface 1212 is inclined relative to the forward projection surface of the air outlet grille 12. The air guide surfaces 1212 of each air guide strip 121 located in the same air guide area 122 have the same inclination direction, so that each air guide surface 1212 located in the same air guide area 122 is formed to be inclined clockwise or counterclockwise as a whole.

[0037] Further, in one embodiment, if Figure 2 and Figure 3 As shown, the air outlet grille 12 further includes a transition area 123, which is located between the two air guide areas 122, and each air guide strip 121 located in the transition area 123 is perpendicular to the projection surface. In other words, the air guide strip 121 located in the transition area 123 will not change the direction of the air flow passing through the air outlet grille 12, and provide space for the air flow gathering in the air guide area 122.

[0038] Specifically, the outer frame 124 of the air outlet grille 12 may be circular. Figure 2 and Figure 3 As shown, a connecting plate 125 is provided in the middle of the air outlet grille 12 , one end of each of the air guide strips 121 gathered in the middle of the air outlet grille 12 is connected to the connecting plate 125 , and the other end of each of the air guide strips 121 is connected to the outer frame 124 .

[0039] Furthermore, in one embodiment, the air outlet grille 12 is rotatably connected to the air guide tube 11, so that the air outlet grille 12 can rotate at the air outlet. Thus, the airflow blown out from the air outlet grille 12 can cover a larger range. When applied to the disinfection machine body 21, the disinfection effect can be further improved.

[0040] Specifically, Figure 3 As shown, the outer frame 124 of the air outlet housing is provided with a protrusion 13. Figure 6As shown, the inner side surface or end surface at the air outlet of the air guide tube 11 is provided with an annular limiting groove 111, and the protrusion 13 is inserted into the limiting groove 111. One end of the protrusion 13 located in the limiting groove 111 can be limited in the limiting groove 111 and move circumferentially in the limiting groove 111. In other words, when the air outlet grille 12 rotates relative to the air guide tube 11, the protrusion 13 moves circumferentially in the limiting groove 111. The air outlet grille 12 can rotate relative to the air guide tube 11 through the cooperation between the protrusion 13 of the outer ring and the limiting groove 111, so that there is no need to set a support structure in the air guide tube 11, and this support structure is extended to the middle part of the air outlet grille 12 to realize the connection between the two. Thereby further reducing the obstruction to the air flow discharged by the air guide tube 11 and ensuring the final gas flow rate.

[0041] like Figure 3 As shown, there may be a plurality of protrusions 13 , and the plurality of protrusions 13 are evenly spaced in the circumferential direction of the outer frame 124 .

[0042] Furthermore, in one embodiment, the outer frame 124 of the air outlet housing is arranged opposite to the end surface of the air guide tube 11 at the air outlet, and the limiting groove 111 is arranged on the end surface of the air guide tube 11 at the air outlet. The opening width of the limiting groove 111 is smaller than the width of the bottom space in the limiting groove 111, which can be understood as the limiting groove 111 being a T-shaped groove at the end surface. Figure 5 As shown, the protrusion 13 includes a connecting rod 131 and a limiting rod 132, and the connecting rod 131 is vertically connected to the limiting rod 132. The limiting rod 132 is located in the limiting groove 111, and the length of the limiting rod 132 is between the width of the bottom of the limiting groove 111 and the opening width of the limiting groove 111, and the diameter of the limiting rod 132 is smaller than the opening width of the limiting groove 111. The connecting rod 131 is rotatably connected to the outer frame 124, and the rotating shaft is the axis of the connecting rod 131 itself. During the assembly process, the connecting rod 131 is first rotated so that the limiting rod 132 is arranged roughly along a direction tangent to the limiting groove 111. In this state, the limiting rod 132 is inserted into the limiting groove 111. Then rotate the connecting rod 131, as shown in FIG. Figure 6 As shown, the limiting rod 132 is intercepted laterally in the limiting groove 111, and the limiting rod 132 is limited in the limiting groove 111, so that the air outlet grille 12 is limited at the air outlet of the air guide tube 11, and at the same time can rotate relative to the air guide tube 11.

[0043] Furthermore, if Figure 1As shown, in one embodiment, the air outlet device 10 also includes a temperature and humidity module 14 for adjusting temperature and humidity. The temperature and humidity module 14 is arranged at the air inlet of the air guide tube 11, and the outlet of the temperature and humidity module 14 is connected to the air inlet. The inlet of the temperature and humidity module 14 is used to connect to the air outlet of an external device.

[0044] After the airflow discharged from the external device passes through the temperature and humidity module 14, the temperature and humidity of the airflow are adjusted, so that the temperature and humidity of the air finally discharged from the air guide tube 11 can meet the different needs of users and improve the user experience. Specifically, the temperature and humidity module 14 may include a humidifying component and a heating component. The humidifying component provides humidity in the channel of the temperature and humidity module 14, thereby regulating the humidity of the gas discharged by the air outlet device 10. The heating component can provide heat to the gas in the channel of the temperature and humidity module 14, and regulate the temperature of the gas discharged by the air outlet device 10.

[0045] Furthermore, in one embodiment, the temperature and humidity module 14 is rotatably connected to the air guide tube 11. The air guide tube 11 can rotate relative to the temperature and humidity module 14 to further adjust the air outlet direction so that the airflow covers a wider range. Figure 1 As shown, the air guide tube 11 can rotate relative to the temperature and humidity module 14 with the longitudinal axis of the temperature and humidity module 14 as the rotation axis.

[0046] Specifically, in one embodiment, a bearing is provided between the temperature and humidity module 14 and the air guide tube 11 to ensure smooth rotation between the temperature and humidity module 14 and the air guide tube 11 .

[0047] Optionally, the temperature and humidity module 14 and the air guide tube 11 may be directly mounted on each other, so that the air guide tube 11 and the temperature and humidity module 14 can rotate.

[0048] Furthermore, in one embodiment, the air outlet device 10 also includes a rotating driving component, and the outer side surface of the air inlet end of the air guide tube 11 is provided with a circle of external threads. The rotating driving component is located outside the channel of the temperature and humidity module 14 and the air duct of the air guide tube 11, and the rotating driving component is provided with meshing teeth, and the meshing teeth cooperate with the external threads.

[0049] When the air outlet direction of the air guide tube 11 needs to be adjusted, the rotary drive member is started, and the air guide tube 11 is rotated by the engagement teeth and the external thread. Specifically, the rotary drive member can be a motor, a gear is arranged on the rotating shaft of the motor, the engagement teeth are teeth of the gear, and the gear is engaged with the external thread.

[0050] Since the rotary drive member is located outside the passage of the temperature and humidity module 14 and the air duct of the air guide cylinder 11 , the arrangement of the rotary drive member will not affect the circulation of the air flow in the air duct.

[0051] Specifically, a first rotating button and a temperature and humidity control button may be provided on the air outlet device 10. The first rotating button is electrically connected to the rotating drive member to control the start and stop of the rotating drive member, thereby controlling the rotation of the air guide tube 11. Similarly, the temperature and humidity control button is electrically connected to the temperature and humidity module 14 to control the start and stop of the temperature and humidity module 14.

[0052] Further, in one embodiment, if Figure 1 As shown, the air outlet device 10 further includes a temperature and humidity detection module 15 for detecting temperature and humidity. The temperature and humidity detection module 15 is arranged at the inlet of the temperature and humidity module 14, the outlet of the temperature and humidity detection module 15 is connected to the inlet of the temperature and humidity module 14, and the inlet of the temperature and humidity detection module 15 is used to communicate with the air outlet of an external device.

[0053] When the temperature and humidity detection module 15 detects that the temperature and / or humidity of the air flow does not meet the user's needs, the temperature and humidity detection module controls the temperature and humidity module 14 to start and adjust the temperature and humidity in the channel. Specifically, the air outlet device 10 may be provided with an intelligent module that can interact with the user, and the user sets the required target temperature and target humidity through the intelligent module. The intelligent module is electrically connected to the temperature and humidity detection component. When the temperature and humidity detected by the temperature and humidity detection module 15 are inconsistent with the target temperature and target humidity, the temperature and humidity module 14 starts to regulate. Specifically, the temperature and humidity detection module 15 includes an outer cylinder 151 and a temperature detection component and a humidity detection component arranged in the outer cylinder 151. One end of the outer cylinder 151 is connected to the inlet of the temperature and humidity module 14, and the other end of the outer cylinder 151 is used to communicate with the air outlet of the external device. The temperature detection component and the humidity detection component can respectively detect the temperature and humidity of the air flow in the outer cylinder 151.

[0054] Further, in one embodiment, if Figure 7 As shown, an elastic buckle 1511 is provided at the inlet of the temperature and humidity detection module 15 for clamping with the air outlet of an external device.

[0055] During use, the inlet end of the temperature and humidity detection module 15 is pressed against the outlet of the external device, and the elastic buckle 1511 is pressed against the outer side of the external device, thereby fixing the air outlet device 10 on the external device.

[0056] Specifically, in one embodiment, the temperature and humidity detection module 15 includes the outer cylinder 151, and the elastic buckle 1511 is arranged on the inner side of the outer cylinder 151. There are multiple elastic buckles 1511, and the multiple elastic buckles 1511 are arranged at intervals in the circumferential direction of the outer cylinder 151.

[0057] Furthermore, in one embodiment, in order to ensure the sealing of the connection between the temperature and humidity detection module 15 and the external device after the two are assembled, a sealing member is provided on the inner side surface at the inlet of the temperature and humidity detection module 15. When the temperature and humidity detection module 15 is clamped at the air outlet of the external device, the sealing member is pressed between the temperature and humidity detection module 15 and the external device.

[0058] Further, in another embodiment, if Figure 8 As shown, an air disinfector 20 is provided, comprising a disinfector body 21 and the above-mentioned air outlet device 10 , wherein the air outlet of the disinfector body 21 is connected to the air inlet of the air guide tube 11 .

[0059] The above scheme provides an air disinfector 20, by setting the air outlet device 10 described in any of the above embodiments on the disinfector body 21, thereby changing the original air exhaust direction during sterilization. In particular, Fig. 9 As shown, when the air outlet of the original disinfection machine body 21 is facing upward, foreign matter is easy to fall into the disinfection machine body 21, affecting its normal operation and service life. By providing the air outlet device 10, the original air outlet direction can be changed to prevent foreign matter from falling into the disinfection machine body 21. In addition, the flow rate of the exhaust gas during sterilization and disinfection can be maintained, thereby improving the sterilization and disinfection effect.
