[0002] A projector is a device that can project videos, images, text, etc. onto a screen for display. It is widely used in homes, offices, schools, cinemas, and other places.

[0003] Projectors contain a large number of electronic components. With the development of technology, the performance of electronic components is becoming more and more powerful, and the requirements for heat dissipation are becoming more and more stringent. Projectors generate a lot of heat during operation. Traditional projectors have slow heat dissipation efficiency and cannot dissipate heat quickly and comprehensively, which affects the normal working time of the projector. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a high heat dissipation projector to solve the technical problem of slow heat dissipation efficiency in the existing technology.

[0005] This utility model is achieved by the following technical solution: a high heat dissipation projector, comprising a housing, a heat dissipation chamber and a fan;

[0006] Both ends of the housing are provided with heat dissipation holes, and the bottom inner side of the housing is provided with multiple air guide vanes. The multiple air guide vanes are arranged in parallel at intervals, and an air duct is formed between two adjacent air guide vanes. The air duct corresponds to the heat dissipation holes.

[0007] The heat dissipation chamber is disposed inside the housing and is used to house the optical devices and electronic components of the projector. The top of the heat dissipation chamber is provided with an air inlet and the bottom of the heat dissipation chamber is provided with an air outlet.

[0008] The fan is disposed inside the housing and is located below the heat dissipation chamber. The air inlet of the fan is connected to the air outlet, and the air outlet of the fan is connected to the air duct.

[0009] In one possible implementation, the housing is further provided with a plurality of dispersion plates, each of which is located within a respective air duct.

[0010] In one possible implementation, the lower end of the heat dissipation chamber is also provided with a plurality of air guide vanes and a dispersion vane, wherein each air guide vane on the heat dissipation chamber is in contact with each air guide vane on the housing, and each dispersion vane on the heat dissipation chamber is in contact with each dispersion vane on the housing.

[0011] In one possible implementation, the heat dissipation chamber is provided with a dust removal port, and the dust removal port is covered with light-blocking foam.

[0012] In one possible implementation, the housing is detachably provided with a foam cover, the foam cover having a receiving groove, and the light-blocking foam being disposed within the receiving groove.

[0013] In one possible implementation, the housing includes an upper shell, a lower shell, a first side plate, and a second side plate connected to each other. The lower shell is provided with a stud and a positioning baffle. The stud is connected to the positioning baffle. The heat dissipation chamber is fixed on the stud. The fan is disposed inside the positioning baffle.

[0014] In one possible implementation, the air guide vane comprises a series of continuous sections with an included angle between adjacent sections, such that the air duct formed by two adjacent air guide vanes is in a curved forward state.

[0037] like Figure 1-7 The projector shown includes a housing 1, a heat dissipation chamber 2, and a fan 3. Heat dissipation holes 11 are provided at both ends of the housing 1. Multiple air guide vanes 12 are provided at the bottom inner side of the housing 1, arranged parallel to each other at intervals. An air duct is formed between two adjacent air guide vanes 12, and the air duct corresponds to the heat dissipation holes 11. The heat dissipation chamber 2 is disposed inside the housing 1 and is used to house the projector's optical and electronic components. An air inlet 21 is provided at the top of the heat dissipation chamber 2, and an air outlet 22 is provided at the bottom of the heat dissipation chamber 2. The fan 3 is disposed inside the housing 1 and located below the heat dissipation chamber 2. The air inlet of the fan 3 is connected to the air outlet 22, and the air outlet of the fan 3 corresponds to the air duct. It should be noted that since the air inlet is located at the top of the heat dissipation chamber 2, when the fan 3 draws air, the air enters from the heat dissipation hole 11 on the side of the housing 1, then flows to the top and enters the heat dissipation chamber 2 from the air inlet. This improves the airflow within the housing 1 and prevents localized overheating due to poor air circulation. In addition, heat dissipation grooves 24 are provided at both the upper and lower ends of the heat dissipation chamber 2. These grooves 24 can improve the air intake / exhaust efficiency and allow the hot air in the heat dissipation chamber 2 to dissipate into the housing 1, thereby improving the heat dissipation efficiency of the heat dissipation chamber 2. Heat dissipation holes 11 are also provided at the lower end of the housing 1 to further improve the heat dissipation efficiency of the housing 1. The air guide 12 increases the contact area between the air and the housing 1, so that the air can carry away more heat when it is blown out, which is beneficial to improving the heat dissipation efficiency of the projector.

[0038] The beneficial effects of this utility model are as follows: air enters from the heat dissipation hole 11 at one end of the housing 1, and then enters the heat dissipation chamber 2 from the air inlet 21. The fan 3 draws out the hot air from the heat dissipation chamber 2 and blows the hot air out from the heat dissipation hole 11 at the other end of the housing 1 to form a wind circulation. The air duct can guide the hot air and prevent air backflow, which greatly improves the heat dissipation efficiency of the projector.

[0039] Please refer to Figure 4In one possible implementation, the housing 1 is further provided with a plurality of dispersion plates 13, each dispersion plate 13 being located in a respective air duct. It should be noted that the number of air guide plates 12 and the number of dispersion plates 13 can be freely set according to the actual situation. The length of the dispersion plate 13 is less than the length of the air guide plate 12. Each dispersion plate 13 is respectively arranged in a respective air duct, which is conducive to dispersing the force in the air duct, thereby reducing noise and further preventing air backflow, which is conducive to improving the user experience.

[0040] Please refer to Figure 6 In one possible implementation, the lower end of the heat dissipation chamber 2 is also provided with multiple air guide vanes 12 and dispersion vanes 13. Each air guide vane 12 on the heat dissipation chamber 2 is in contact with each air guide vane 12 on the housing 1, and each dispersion vane 13 on the heat dissipation chamber 2 is in contact with each dispersion vane 13 on the housing 1. It should be noted that the air guide vanes 12 and dispersion vanes 13 are at the same height. After the air guide vanes 12 and dispersion vanes 13 on the heat dissipation chamber 2 come into contact with the air guide vanes 12 and dispersion vanes 13 on the housing 1, a complete air duct can be formed, which can increase the height of the air duct so that the height of the air duct can meet the height of the air outlet of the fan 3, ensuring that all the air blown out by the fan 3 can pass through the air duct, improving the efficiency of air passing through the air duct. In addition, when the air is blown out of the air duct, it can also carry heat from the air guide vanes 12 and dispersion vanes 13 of the heat dissipation chamber 2, so as to further improve the heat dissipation efficiency of the heat dissipation chamber 2.

[0041] Please refer to Figure 2 and Figure 5 In one possible implementation, the heat dissipation chamber 2 is provided with a dust removal port 23, and the dust removal port 23 is covered with light-shielding foam 14. It should be noted that after prolonged use, dust will accumulate inside the projector. The dust removal port 23 allows users to easily clean certain areas inside the heat dissipation chamber 2 using auxiliary tools. At the same time, since some optical components are located inside the heat dissipation chamber 2, the light-shielding foam 14 is used to seal the dust removal port 23, preventing light leakage and improving the user experience.

[0042] Please refer to Figure 2 In one possible implementation, a foam cover 15 is detachably provided on the housing 1, and the foam cover 15 has a receiving groove, in which the light-blocking foam 14 is disposed. It should be noted that the foam cover 15 can be detachably connected to the housing 1 by means of a snap-fit, so as to facilitate the installation / removal of the foam cover 15. During the use of the projector, some dust spots may appear on its lens, affecting the user's viewing experience. If the user wipes it with a tissue or cloth, it may not only be ineffective but may also cause the dust spots to spread. At this time, the user only needs to remove the foam cover 15 and use the light-blocking foam 14 to clean the dust spots, which is very convenient and greatly improves the user experience.

[0043] Please refer to Figure 2and Figure 4 In one possible implementation, the housing 1 includes an upper housing 16, a lower housing 17, a first side plate 18, and a second side plate 19 that are connected to each other. The lower housing 17 is provided with a stud 171 and a positioning baffle 172. The stud 171 is connected to the positioning baffle 172. The heat dissipation chamber 2 is fixed on the stud 171. The fan 3 is located inside the positioning baffle 172. It should be noted that the upper shell 16 and the lower shell 17 can be fixedly connected by bolts. The upper and lower ends of the first side plate 18 are respectively snapped to the upper shell 16 and the lower shell 17. The upper and lower ends of the second side plate 19 are also respectively snapped to the upper shell 16 and the lower shell 17. Furthermore, both sides of the upper shell 16 and the lower shell 17 are provided with limiting grooves 161. The edges of the first side plate 18 and the second side plate 19 are respectively inserted into the limiting grooves 161 of the upper shell 16 and the lower shell 17 to ensure the stability of the shell 1. In addition, the stud 171 can provide an installation base for the heat dissipation chamber 2, so that the heat dissipation chamber 2 is fixed on the lower shell 17 and suspended above the bottom surface of the lower shell 17, which is convenient for the heat dissipation chamber 2 to dissipate heat. It can also allow the fan 3 to be installed directly below the heat dissipation chamber 2 so that the fan 3 can draw out the air in the heat dissipation chamber 2. The positioning baffle 172 can play a role in positioning and limiting the fan 3, so as to facilitate the quick positioning and installation of the fan 3.

[0044] Please refer to Figure 4 In one possible implementation, the air guide vane 12 comprises multiple continuous sections, with an obtuse angle between adjacent sections, so that the air duct formed by two adjacent air guide vanes 12 is in a curved forward state. Specifically, in this embodiment, the air guide vane 12 comprises three continuous sections, with the first and third sections offset and parallel, and the second section inclined. The first and third sections are connected to the first and third sections respectively, and the angles between the first and second sections are both obtuse, ensuring that the air guide vane 12 extends forward as a whole, thus guaranteeing that the air duct is in a curved forward state. This design increases the contact area between the air guide vane 12 and the air, as well as the length of the air duct, allowing more heat to be carried away when the air is blown out, which is beneficial for improving heat dissipation efficiency. Furthermore, the shape of the dispersion plate 13 is similar to that of the air guide vane 12 to ensure the smoothness of the air duct.

[0045] Please refer to Figure 1 In one possible implementation, the system also includes a support 4, with the housing 1 rotatably connected to the support 4. It should be noted that the support 4 provides support for the projector body, allowing the projector to be placed stably on the table, thus improving projection quality. The rotatable connection between the support 4 and the housing 1 facilitates user adjustment of the projector body's tilt angle.

[0046] Please refer to Figure 2 , Figure 3 and Figure 7In one possible implementation, the bracket 4 has two support arms 41, with a rotating shaft 42 on the support arms 41 and a rotating member 5 on the housing 1. The rotating shaft 42 is rotatably connected to the rotating member 5. The outer side wall of the rotating shaft 42 has a snap-fit ​​part 43, and the rotating member 5 has a snap-fit ​​arm 51, which snaps into the snap-fit ​​part 43. It should be noted that the rotating part 5 is fixed to the lower shell 17 by bolts. The locking part 43 is arranged around the outer wall of the rotating shaft 42. The locking part 43 is wavy with crests and troughs. The locking arm 51 is elastic and can rotate relative to the locking part 43. Under normal conditions, the locking arm 51 is located in the trough of the locking part 43. When an external force drives the shell 1 to rotate, the rotating part 5 rotates with the shell 1, and the locking arm 51 rotates along the locking part 43. Each time the locking arm 51 contacts the crest of the locking part 43, an elastic deformation occurs. In addition, there are four locking arms 51. The four locking arms 51 are evenly spaced around the rotating part 5, which helps to improve the stability of the locking between the shell 1 and the bracket 4 and ensures that the shell 1 will not rotate unexpectedly when there is no external force.

[0047] Please refer to Figure 5 In one possible implementation, a PCB board 6 is also included, which is fixedly disposed on the top surface of the heat dissipation chamber 2. Specifically, the PCB board 6 can be fixed to the top surface of the heat dissipation chamber 2 by bolts, and the PCB board 6 is disposed near the heat dissipation hole 11. Part of the PCB board 6 is located on the top surface of the heat dissipation chamber 2, and another part is suspended outside the heat dissipation chamber 2. This design helps to improve the heat dissipation efficiency of the PCB board 6. In addition, since the PCB board 6 needs to be connected to the electronic components inside the heat dissipation chamber 2, a wire clamp 25 is also provided on the top of the heat dissipation chamber 2, and the wires pass through the wire clamp 25 to ensure the stability of the wire passage.

[0048] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
