Description

Technical Field

[0001] The utility model relates to the technical field of ventilators, in particular to a plastic dustproof outer cover of a ventilator. Background Art

[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. A fan usually uses a power machine (mainly an electric motor) to drive the impeller to rotate in a volute casing, and air is sucked in from the center of the impeller through the air intake port. Due to the dynamic effect of the blades on the gas, the gas pressure and speed are increased, and under the action of centrifugal force, the gas is thrown toward the casing along the blade path and discharged from the exhaust port. When the fan is working, the coal ash, dust, etc. carried in the working space are easily deposited on the blades of the fan, causing the dynamic balance of the rotor to be destroyed. Therefore, a dustproof cover is needed to prevent the fan from dust.

[0003] For example, Chinese patent publication number CN217107560U discloses a plastic dustproof outer cover for a ventilator, which covers the ventilator through the cover body to prevent dust in the air from entering the ventilator and affecting the use of the ventilator. A retractable first pipeline is provided for the air intake of the ventilator, so that the air intake pipeline is single, and a filtering mechanism is provided at the air intake end to ensure the filtering of the intake air, which can effectively prevent dust from entering the ventilator. A second pipeline is provided for the air outlet of the ventilator, so that the overall dustproof effect of the ventilator can be guaranteed without affecting the operation of the ventilator.

[0004] The existing technology has the following problems:

[0005] When the existing dustproof cover is used, since the dustproof cover is spliced ​​and assembled on the outside of the ventilator to cover the ventilator, there is a connecting gap at the splicing of the dustproof cover, and dust can easily enter the cover through the gap, which will affect the normal operation of the ventilator. Moreover, when the dustproof cover covers the ventilator, the air inside the dustproof cover does not circulate, and the heat generated by the ventilator cannot be discharged in time, shortening the service life of the ventilator.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] like Figure 1-Figure 7 As shown, a plastic dustproof cover for a ventilator comprises a base 1, a dustproof cover assembly 2 is fixedly mounted on the upper surface of the base 1 to cover the ventilator for dust protection, a ventilator body 4 is fixedly mounted on the upper surface of the base 1 by screws 3, and the ventilator body 4 is located inside the dustproof cover assembly 2, a heat dissipation assembly 3 is arranged above the base 1 to facilitate heat dissipation of the ventilator, the dustproof cover assembly 2 comprises a cover shell 21, the lower surface of the cover shell 21 is fixedly mounted on the right side of the upper surface of the base 1, and the left side of the cover shell 21 is fixedly mounted on the right side of the upper surface of the base 1. The side is overlapped with a cover shell 22, an air outlet pipe 24 is fixedly installed on the right side of the cover shell 21, an air inlet pipe 28 is fixedly installed on the front side of the cover shell 21, an external threaded ring 211 is fixedly installed on the output end of the fan body 4, and a mounting plate 212 is fixedly installed on the output end of the fan body 4. The heat dissipation component 3 includes two threaded holes 32, and the two threaded holes 32 are opened at the front and rear positions of the upper surface of the cover shell 21, and a heat dissipation hole 31 is opened on the lower surface of the threaded hole 32, and a dustproof net 33 is inserted on the inner surface of the heat dissipation hole 31.

[0029] The external threaded ring 211 and the mounting plate 212 facilitate the installation of the cover shell 22 and the ventilator. The cover shell 1 21 and the cover shell 22 cover the ventilator for protection and dust prevention. The heat dissipation holes 31 enable the flow of air inside the dustproof outer cover assembly 2 and the outside air. The heat generated by the ventilator flows out through the heat dissipation holes 31 and the threaded holes 1 32, which facilitates the heat dissipation of the ventilator and increases the service life of the ventilator. The dustproof net 33 protects the heat dissipation holes 31 and the threaded holes 1 32 from dust, preventing dust from entering the dustproof outer cover.

[0030] like Figure 2-Figure 5As shown, the rear end of the air inlet pipe 28 is rotatably connected with an internal threaded ring 210, the inner surface of the internal threaded ring 210 is threadedly connected with the outer surface of the external threaded ring 211, and a square frame 213 is fixedly installed on the left side of the outer surface of the air outlet pipe 24, and a threaded hole 2 is opened on the left side of the square frame 213, and the inner wall of the threaded hole 2 is threadedly connected with a screw 1 that passes through the mounting plate 212.

[0031] Align the mounting plate 212 on the output end of the fan with the threaded hole 2 on the square frame 213, rotate a pair of screws to fix the mounting plate 212 and the square frame 213, rotate the internal thread ring 210 to make it threadedly connected with the external thread ring 211 on the input end of the fan, and then install the fan on the upper surface of the base 1 with screws 3, and then the fan can be installed in the cover 21, making the installation of the fan more convenient and flexible.

[0032] like Figure 4 , Figure 6 As shown, the inner surface of the air inlet pipe 28 is threadedly connected with a filter frame, the inner surface of the filter frame is fixedly installed with a filter screen 29, and the right side of the inner surface of the air outlet pipe 24 is clamped with a filter screen 214.

[0033] The gas entering the ventilator is filtered through the filter 29 to prevent dust and the like from being deposited on the blades of the ventilator and affecting the use of the ventilator. The threaded action of the filter frame and the air inlet pipe 28 makes it easier to disassemble the filter 29, and to clean the dust on the filter 29 and to replace the filter 29 more conveniently. The filter 2 214 has a dust-proof effect on the outlet pipe 24 to prevent dust and the like from adhering to the outlet pipe 24 and entering the ventilator.

[0034] like Figure 2 , Figure 3 As shown, a mounting strip 27 is fixedly installed on the left side of the cover shell 22, and a threaded hole 3 is opened on the left side of the outer surface of the base 1, and a screw 2 passing through the mounting strip 27 is threadedly connected to the inner wall of the threaded hole 3.

[0035] The second screw is rotated to pass through the mounting strip 27 and screwed into the third threaded hole, so as to facilitate the installation of the second cover shell 22 .

[0036] like Figure 2-Figure 6 As shown, positioning blocks 26 are fixedly installed at the front and rear positions on the right side of the second cover shell 22, and positioning grooves 25 are opened at the front and rear positions on the left side of the first cover shell 21, and the inner surface of the positioning groove 25 is plugged into the outer surface of the positioning block 26.

[0037] The positioning block 26 on the second cover shell 22 is inserted into the positioning groove 25 to achieve a positioning effect for the second cover shell 22 .

[0038] like Figure 2 , Figure 3As shown, a sealing strip 23 is fixedly installed on the left side of the inner surface of the cover shell 1 21, and the material of the sealing strip 23 is polyurethane rubber.

[0039] The sealing strip 23 improves the sealing performance of the connection between the cover shell 1 21 and the cover shell 2 22, thereby preventing dust and the like from entering the ventilator and preventing dust and the like from being deposited on the blades of the ventilator.

[0040] like Figure 7 As shown, an internal thread ring 2 34 is fixedly mounted on the upper end of the outer surface of the dustproof net 33 , and the outer surface of the internal thread ring 2 34 is threadedly connected to the inner surface of the threaded hole 1 32 .

[0041] The inner thread ring 2 34 is rotated, and under the action of the threads of the inner thread ring 24 and the threaded hole 1 32 , it is separated from the cover 1 21 , so that the dustproof net 33 can be disassembled easily.

[0042] The working principle of the present invention is as follows: rotate the internal threaded ring 24 to install the dust screen 33 on the top of the cover shell 22, align the mounting plate 212 on the output end of the fan with the threaded hole 2 opened on the square frame 213, rotate the screw pair to fix the mounting plate 212 and the square frame 213, rotate the internal threaded ring 210 to make it threadedly connected with the external threaded ring 211 on the input end of the fan, and then install the fan on the upper surface of the base 1 through the screw 3, and then insert the positioning block 26 on the cover shell 22 into the positioning groove 25, so that the threaded hole on the mounting strip 27 is aligned with the threaded hole 3 on the left side of the upper surface of the base 1, rotate the screw 2 to make it pass through the mounting strip 27 and screw into the threaded hole 3, and then the installation of the cover shell 21, the cover shell 22, the base 1, and the fan can be completed. , So that the fan is installed in the dustproof outer cover, through the cover shell 21 and the cover shell 22 2 plays a protective role on the ventilator, and thus has a dust-proof effect. When the ventilator is working, air enters the ventilator through the air inlet pipe 28 and the filter screen 29, and then goes out through the air outlet pipe 24. The gas entering the ventilator is filtered by the filter screen 29 to prevent dust and the like from being deposited on the blades of the ventilator and affecting the use of the ventilator. The sealing strip 23 is used to improve the sealing performance of the connection between the cover shell 1 21 and the cover shell 2 22 to prevent dust and the like from entering the ventilator and depositing on the blades of the ventilator. The heat dissipation holes 31 are used to realize the flow of air inside the dustproof outer cover assembly 2 and the outside air. The heat generated by the ventilator flows out through the heat dissipation holes 31 and the threaded holes 32, which is convenient for heat dissipation of the ventilator and improves the service life of the ventilator. The dust-proof net 33 plays a dust-proof role on the heat dissipation holes 31 and the threaded holes 32 to prevent dust and the like from entering the dust-proof outer cover.

[0043] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
