Description
Technical Field
[0001] The utility model relates to the field of vacuum cleaners, in particular to a simple motor cover structure of a vacuum cleaner. Background Art
[0002] In modern household cleaning equipment, as an essential household appliance, the performance and user experience of a vacuum cleaner are directly related to the satisfaction of consumers. However, there is a common problem in the design of many ordinary vacuum cleaners on the market: the fan is directly installed inside the housing, lacking effective heat insulation and noise reduction measures. This design causes the hot air generated by the high-speed rotation of the fan during the operation of the vacuum cleaner to directly escape from the gaps of the housing, such as the gaps of buttons, handles, etc., reducing the comfort of users. At the same time, the noise generated by the operation of the fan is not effectively isolated, further affecting the user experience.
[0003] To solve the above problems, the industry has begun to explore the design scheme of adding a motor cover outside the fan. The introduction of the motor cover can, on the one hand, absorb and reflect noise through its sound insulation material or structural design, significantly improving the sound insulation effect of the vacuum cleaner and providing a quieter use environment for users; on the other hand, the motor cover can also form a relatively enclosed space to effectively guide the hot air generated by the fan to the specially designed air outlet for discharge, thus completely solving the problem of hot air escaping from the gaps of the housing. Although the introduction of the motor cover brings many advantages, its design and manufacturing also correspondingly increase the cost of the vacuum cleaner. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the above technical problems and provide a simple motor cover structure of a vacuum cleaner. This application aims to provide a motor cover structure with low manufacturing cost.
[0005] A simple motor cover structure of a vacuum cleaner includes a housing, a partition, buttons, and a suction fan. The partition is fixed inside the housing to divide the inner cavity of the housing into a first installation cavity and a second installation cavity, and cooperates with the housing to clamp and fix the suction fan in the first installation cavity. An air inlet and an air outlet are provided on the housing corresponding to the position of the first installation cavity, and the buttons are arranged on the housing corresponding to the second installation cavity.
[0006] According to the simple motor cover structure of the vacuum cleaner of the present application, the dust suction fan is clamped and fixed through the cooperation of the partition plate and part of the housing, forming a simple motor cover structure for the dust suction fan. The dust suction fan is covered in the first installation cavity on one side of the partition plate, and the button is arranged on the housing on the other side of the partition plate, so that the hot air blown out by the dust suction fan is restricted in the first installation cavity and blown out of the housing through the air outlet, and will not be blown to the second installation cavity and the button, nor will it be blown out through the gap of the button; the partition plate does not need to wrap the dust suction fan, and the manufacturing cost is relatively lower than that of the motor cover wrapping the dust suction fan, and the product with the partition plate is also relatively quieter than the vacuum cleaner directly installing the dust suction fan in the housing.
[0007] Further, the housing includes a first housing and a second housing. The partition plate is fixed to the lower part of the first housing, so that the partition plate and the lower part of the first housing cooperate to form the first installation cavity. The second housing and the first housing are fixed to each other, so that the partition plate, the second housing and the upper part of the first housing cooperate to form the second installation cavity. Dividing the housing into two housings can facilitate the installation of the partition plate and cooperate to form two installation cavities.
[0008] Still further, the air inlet and the air outlet are arranged on the first housing, and the button is arranged on the second housing.
[0009] Still further, a plurality of positioning plates are arranged on the inner wall of the first housing, and positioning grooves cooperating with the positioning plates are arranged on the partition plate. The positioning plates can not only strengthen the structural strength of the first housing, but also position the installation of the partition plate.
[0010] Still further, clamping parts are arranged at both ends of the dust suction fan, and the housing and the partition plate jointly extend into the cavity to form a clamping plate for clamping the clamping parts.
[0011] Still further, the clamping parts are made of shock-absorbing materials. The clamping parts shock-absorb the dust suction fan, thereby reducing the noise generated during the operation of the vacuum cleaner.
[0012] Still further, a plug-in groove is arranged on the first housing beside the air inlet, and a plug-in plate is also arranged on the partition plate. The partition plate is fixed on the first housing so that the plug-in plate is inserted into the plug-in groove.
[0013] Still further, the dust suction fan is a centrifugal dust suction fan, and the air outlet is arranged on the side of the first housing so that the air outlet is opposite to the air outlet of the dust suction fan.
[0014] Still further, the vacuum cleaner further includes a dust suction air duct, and the dust suction air duct is installed on the housing at the air inlet.
[0015] Still further, the upper part of the first housing and the second housing cooperate to form a handle. Brief Description of the Drawings

[0020] A simple motor cover structure of a vacuum cleaner according to the present utility model will be described with reference to the accompanying drawings.
[0021] As Figures 1 to 4 shown, a simple motor cover structure of a vacuum cleaner simplifies the structure of the motor cover and has most of the functions of the motor cover, making the manufacturing cost of the vacuum cleaner lower. The simple motor cover structure of the vacuum cleaner includes a housing, a partition, a button, and a suction fan. The partition is fixed inside the housing to divide the inner cavity of the housing into a first installation cavity and a second installation cavity, and cooperates with the housing to clamp and fix the suction fan in the first installation cavity. An air inlet and an air outlet are provided on the housing corresponding to the position of the first installation cavity. The button is arranged on the housing corresponding to the second installation cavity. The suction fan is clamped and fixed by the cooperation of the partition and a part of the housing to form a simple motor cover structure of the suction fan. Since the partition of the present application does not need to completely wrap the suction fan, the structure is simpler than the motor cover structure that completely wraps the suction fan, is easy to manufacture and has a lower cost. Moreover, the partition cooperates with the housing forming the first installation cavity to guide the hot air blown out by the suction fan, so that the hot air can only exit through the air outlet on the housing and will not exit through the gap of the button. And the presence of the partition also makes the product of the vacuum cleaner with the suction fan directly installed in the housing quieter.
[0022] As Figure 2 shown, in the embodiment shown in the drawings of the present application, the housing includes a first housing and a second housing. Dividing the housing into two housings can facilitate the installation of the partition and other parts. The partition is fixed to the lower part of the first housing, so that the partition and the lower part of the first housing cooperate to form the first installation cavity. The second housing is fixed to the first housing, so that the partition, the second housing, and the upper part of the first housing cooperate to form the second installation cavity. The upper part of the first housing cooperates with the second housing to form a handle. Due to the blocking of the partition, the hot air blown out by the suction fan will not blow into the handle either.
[0023] The air inlet and the air outlet are arranged on the first housing, and the button is arranged on the second housing. As Figure 2 shown, the air inlet is arranged on the bottom surface of the first housing, and the air outlet is arranged on the side surface of the first housing. The dust suction fan is a centrifugal dust suction fan, so that the air outlet is opposite to the air outlet of the dust suction fan, and the air inlet is opposite to the air inlet of the dust suction fan.
[0024] As Figure 1 and Figure 4 shown, the vacuum cleaner further includes a dust suction air duct, and the dust suction air duct is installed on the housing at the air inlet, and the dust suction air duct cooperates with the dust suction fan to suck and collect dust.
[0025] As Figure 2 and Figure 4 shown, the first housing is provided with a plug-in groove beside the air inlet, and the partition board is also provided with a plug-in board. The partition board is fixed on the first housing so that the plug-in board is inserted into the plug-in groove. The mutually plug-in structure can make the partition board more stably fixed on the first housing, and the two support each other to improve the structural strength, and it will not vibrate easily and generate noise. Moreover, the cut-off gap formed by the plug-in groove and the plug-in board has a certain sealing effect to prevent air leakage from the first cavity.
[0026] As Figure 2 and Figure 3 shown, a plurality of positioning plates are arranged on the inner wall of the first housing, and positioning grooves matched with the positioning plates are arranged on the partition board. The positioning plates are also the reinforcing ribs of the first housing. The positioning plates can not only strengthen the structural strength of the first housing, but also position the installation of the partition board.
[0027] As Figures 2 to 4 shown, clamping portions are arranged at both ends of the dust suction fan, and the housing and the partition board jointly extend into the cavity to form clamping plates for clamping the clamping portions.
[0028] The clamping portion is a clamping portion made of shock-absorbing material, and the shock-absorbing material can be a soft material such as silica gel or rubber.
[0029] According to the disclosure and teaching of the above specification, those skilled in the art to which the present invention pertains can also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
