[0030] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are only some of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] A side air outlet vacuum cleaner main body in the preferred embodiment of the present utility model; as Figures 1-3As shown in the figure, it includes a housing 10. The overall shape of the housing is T-shaped, and a motor assembly 70 is arranged inside the upper horizontal part. An air inlet 100 is arranged on the left side of the horizontal part, and a housing air outlet 108 is arranged on the right side. A wind deflector 20 is connected to the housing air outlet. Four groups of air outlets 200 are arranged on the side of the wind deflector. When the fan assembly works, a negative pressure is generated inside the housing, so that the fluid enters the housing through the air inlet, enters the wind deflector through the housing air outlet, and under the action of the wind deflector, the fluid is discharged through the side air outlets. The lower vertical part of the housing forms a handle 102. The lower end of the handle is connected to a frustum-shaped bottom 103. A silica gel gasket 50 is arranged on the frustum-shaped bottom to increase the friction force after the vacuum cleaner main body is placed. And a control board 40, a display screen 400 and a switch 401 connected to the control board are arranged inside the bottom. The vacuum cleaner main body starts or stops working through the switch. A battery 90 connected to the control board is arranged inside the handle 102. The display screen can display the remaining power of the battery. A charging port and the like can also be arranged on the bottom shell to charge the battery, and an indicator light is arranged to display the working state of the vacuum cleaner main body. Control buttons 30 are arranged on the side of the handle. The control buttons and the motor assembly 70 are both connected to the control board, and the control buttons change the rotation of the motor assembly to change the working state of the vacuum cleaner, thereby changing the flow rate of the fluid.

[0032] Specifically, as Figures 2-3 , Figures 7-9 and Figure 11 shown, the motor assembly 70 includes a motor 701 and a silica gel sleeve 700 sleeved outside the motor. An air flow inlet 703 is arranged on one side of the motor. The air flow inlet is aligned with the air inlet. The fluid enters the interior of the motor through the air flow inlet. An air flow outlet 704 is arranged on the other side of the motor, and a wind deflector 702 is arranged at the air flow outlet. The flow direction of the fluid is changed through the wind deflector. An isolation plate 109 is arranged between the air inlet and the housing air outlet of the housing 100. The motor assembly is placed between the isolation plate and the air inlet, and the wind deflector and the isolation plate are in the same vertical plane and there is a gap between them to form a wind guiding channel 80. The wind guiding channel and the air flow outlet are at different horizontal planes. Thus, the fluid flows closer to the inner wall of the housing inside the housing, improving the fluid flow rate. And in order to make more of the fluid coming out of the air flow outlet enter the wind guiding channel, a sealing structure is formed between the silica gel sleeve and the housing. The silica gel sleeve not only ensures that more fluid at the air flow outlet enters the wind guiding channel, but also can slow down the transmission of vibration during the operation of the motor and can isolate the noise during the operation of the motor.

[0033] Furthermore, as Figure 4 and Figure 6As shown, an inner groove 1080 is provided in the air outlet 108 of the housing. The isolation net 60 is placed at the inner groove, and large particle objects are prevented from entering the interior of the vacuum cleaner main body through the air outlet by the isolation net 60. At the same time, rotating parts 106 are provided on both the left and right sides of the housing. Clamping blocks 107 are provided on the rotating parts. The clamping blocks include clamping grooves 1070 and arc-shaped connecting parts 1071 provided on both sides of the clamping grooves. Other accessories and the wind shield are detachably connected to the vacuum cleaner main body at the rotating parts. A fitting connection ring 101 is provided on one side of the air inlet, and accessories such as a vacuum cleaner head can also be connected through the fitting connection ring.

[0034] Further, as Figures 4-5 shown, the wind shield 20 is provided at the air outlet of the housing and is rotationally clamped with the rotating part 106 to achieve detachable connection. The wind shield 20 includes a wind shield connection ring 204 sleeved outside the rotating part. A locking groove 202 corresponding to the clamping block is provided on the inner wall of the wind shield connection ring. The locking groove is L-shaped. After inserting the clamping block into the locking groove and rotating, the wind shield can be connected to the housing. To further enhance the stability of the connection, a clamping post 203 is provided in the middle of the locking groove. The clamping post corresponds to the clamping groove. Rotating the wind shield makes the clamping post rotate on the arc-shaped connecting part and then enter the clamping groove, thereby achieving a clamping effect. The arc-shaped connecting part also facilitates the rotation of the wind shield. Four groups of air outlets 200 are provided on the side of the wind shield connection ring, and a rear plate 201 is connected to the other end of the wind shield connection ring. The area of the rear plate is larger than the radius of the wind shield connection ring. At the same time, an arc-shaped air guiding part 205 is provided on the periphery of the rear plate. The fluid coming out through the air outlets 200 can also change the flow direction of the fluid at the arc-shaped air guiding part, preventing the fluid coming out of the housing air outlet from directly blowing towards the human face. The air outlets change the direction of the fluid coming out of the housing air outlet, ensuring that the fluid coming out of the air outlet of the vacuum cleaner main body is not aligned with the face, avoiding dust and the like from blowing towards the face, and making the use of the vacuum cleaner main body safer and healthier for the human body.

[0035] Further, as Figures 9-12 shown, to increase the sealing performance of the housing, the housing 10 includes a left housing 104 and a right housing 105. Sealing posts 1040 are provided on the periphery of the left housing, and corresponding sealing grooves 1050 are provided on the periphery of the right housing. Inserting the sealing posts into the sealing grooves improves the sealing performance of the housing. Multiple groups of clamping blocks 1051 are provided on the right housing, and corresponding clamping grooves 1041 are provided on the left housing, thereby realizing the snap connection between the left housing and the right housing and facilitating the disassembly of the housing. At the same time, since the housing forms a handle, it is convenient to hold and use the vacuum cleaner main body; and the area of the bottom also facilitates the placement of the vacuum cleaner main body, making it more convenient to use.

[0036] A side-outlet vacuum cleaner according to a preferred embodiment of the present utility model includes the above-mentioned side-outlet vacuum cleaner main body, and also includes accessories such as a nozzle brush, a slender nozzle, a mite removal nozzle, a round and flat long nozzle, a nozzle brush, and a flat nozzle connected to the vacuum cleaner main body. The above-mentioned accessories are connected to the accessory connection ring and the rotating part of the air inlet. When the motor rotates, a negative pressure is formed in the housing, and the suction nozzle and other accessories can be connected to form a vacuum cleaner. When the motor rotates, the air inlet is blown to connect the nozzle-like accessories for cleaning operations.

[0037] It should be understood that the present utility model is described by means of some embodiments. Those skilled in the art know that without departing from the spirit and scope of the present utility model, various changes or equivalent substitutions can be made to these features and embodiments. In addition, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model.
