DETAILED DESCRIPTION

[0022] The specific embodiments of the utility model will be further described in detail below in combination with the accompanying drawings, so that the technical scheme of the utility model is easier to understand and master. It should be understood that the specific embodiments described herein are only used to explain the utility model and do not limit the utility model.

[0023] The embodiment provides a magnetic table dust collector, as shown in the figure, comprising a mounting seat 1, an upper shell 2 and a lower shell 3, the upper shell 2 is fixed on the mounting seat 1 and covers the upper end of the mounting seat 1, the lower shell 3 has a storage cavity for containing garbage, the lower shell 3 is provided with a first lower magnetic attraction member 31, the mounting seat 1 is provided with a second lower magnetic attraction member 11, the first lower magnetic attraction member 31 and the second lower magnetic attraction member 11 are attracted to each other to fix the lower shell 3 on the mounting seat 1. Figures 1-4 Compared with the rotating clamping, the magnetic design makes the installation and dismounting of the lower shell 3 more convenient. The user only needs to approach the lower shell 3 to the mounting seat 1, and the magnetic attraction member can be automatically attracted and fixed; when dismounting, the lower shell 3 can be easily taken off by overcoming a small magnetic force, and the operation process is simple and fast, without complex rotating action.

[0024] The attraction force between the magnetic attraction members can provide a relatively stable fixing effect, so that the lower shell 3 will not easily fall off during the normal use of the table dust collector. As long as the magnetic strength of the magnetic attraction member is reasonably designed, the stability requirement of the dust collector in various use scenarios can be met.

[0025] Since there is no deformation problem of plastic parts caused by excessive rotating force in the rotating clamping, the magnetic design effectively protects the lower shell 3 and other parts, prolongs their service life, avoids the damage of the dust collector caused by the separation of the buckle from the clamping groove, and improves the reliability of the product. The type and thickness of the plastic used for the lower shell 3 can also have a large selection space, which is conducive to reducing the cost.

[0026] As shown in the figure,

[0027] , Figure 3 , 4As shown, the lower end of the mounting seat 1 is located in the lower shell 3, the second lower magnetic attraction member 11 is fixed at the lower end of the mounting seat 1, and the first lower magnetic attraction member 31 is fixed at the bottom of the lower shell 3. In this way, the lower end of the mounting seat 1 and the lower shell 3 form a sealed contact, so that the airflow can flow out of the specific air outlet, facilitating the filtration of the airflow. The internally arranged magnetic attraction member is not easily disturbed and damaged by the external environment, such as dust, water vapor, etc., which cannot directly contact the magnetic attraction member, reducing the risk of performance decline of the magnetic attraction member and prolonging its service life. At the same time, this design also avoids accidental collision or scratching of the magnetic attraction member in daily use, protecting the integrity and magnetic strength of the magnetic attraction member.

[0028] As shown in Figure 3 , 4 , the lower end of the mounting seat 1 has an annular wall 14, the annular wall 14 has a first air outlet 141, the annular wall 14 is inclined inward from top to bottom, and the thickness of the annular wall 14 gradually decreases from top to bottom, the bottom of the lower shell 3 has an annular rib 32, the lower end of the annular wall 14 is fitted inside the annular rib 32, and the second lower magnetic attraction member 11 is annular and fixed at the lower end of the annular wall 14. The inclination and thickness variation design of the annular wall 14 is beneficial to guiding the airflow and facilitating cooperation with the annular rib 32 to prevent misalignment or shaking between the two; the annular second lower magnetic attraction member 11 provides uniform magnetic force to tightly attract the lower shell 3 and the mounting seat 1 together. In other alternative embodiments, the annular wall 14 can also be of equal thickness, and the annular wall 14 can also be vertically extended.

[0029] As shown in Figure 3 , the upper end of the lower shell 3 and the mounting seat 1 have a gap. In this way, the lower shell 3 and the mounting seat 1 can be fixed by contact attraction through the first lower magnetic attraction member 31 and the second lower magnetic attraction member 11.

[0030] As shown in Figure 3 , 4 , the upper shell 2 is provided with a first upper magnetic attraction member 21, the mounting seat 1 is provided with a second upper magnetic attraction member 12, and the first upper magnetic attraction member 21 and the second upper magnetic attraction member 12 are attracted to each other to fix the upper shell 2 on the mounting seat 1. Compared with the traditional screw fastening or buckle connection method, the magnetic attraction type fixing greatly simplifies the assembly and separation process of the upper shell 2 and the mounting seat 1. The user only needs to align the upper shell 2 with the mounting seat 1 and approach gently, and the magnetic attraction member will automatically attract and complete the installation; when disassembling, only a certain magnetic force needs to be overcome, and the upper shell 2 can be easily removed without the need for additional tools, greatly improving the convenience of operation.

[0031] As shown in Figures 1-4As shown, the side wall of the upper shell 2 has a pressing part 22, and the pressing part 22 has a clamping position 23, so that when the pressing part 22 is pressed, the clamping position 23 is clamped with the mounting seat 1. When the upper shell 2 is installed on the mounting seat 1, the pressing part 22 is in an initial state without being pressed. Once the user manually presses the pressing part 22, the pressing part 22 is deformed under the force, so that the position of the clamping position 23 on the pressing part 22 changes, and the corresponding structure on the mounting seat 1 forms a clamping fit. This design utilizes the elastic deformation characteristics of the material, and the pressing part 22 can be deformed under the force and restored, so as to realize the clamping and unclamping operations. When it is necessary to disassemble the lower shell 3 for garbage cleaning and the like, the stable connection design of the upper shell 2 and the mounting seat 1 can avoid accidental falling of the upper shell 2 due to misoperation. After the lower shell 3 is disassembled, if the upper shell 2 is to be disassembled, the user only needs to release the pressure on the pressing part 22, and the pressing part 22 rebounds to make the clamping position 23 disengage from the clamping groove or clamping buckle of the mounting seat 1. At this time, the adsorption force of the magnetic attraction is overcome, and the upper shell 2 can be easily taken off, greatly simplifying the disassembly steps and improving the operation convenience. The pressing part 22 is formed by two notches provided on the side wall of the upper shell 2, and the lower end of the pressing part 22 is flush with the lower end of the upper shell 2.

[0032] In other optional embodiments, the adsorption force between the first upper magnetic attraction part 21 and the second upper magnetic attraction part 12 is greater than the adsorption force between the first lower magnetic attraction part 31 and the second lower magnetic attraction part 11. The adsorption force between the first upper magnetic attraction part 21 and the second upper magnetic attraction part 12 is greater than the adsorption force between the first lower magnetic attraction part 31 and the second lower magnetic attraction part 11. The upper shell 2 covers the motor 151, control circuit, battery 152 and the like of the dust collector, and the stronger adsorption force can ensure that the upper shell 2 is firmly fixed on the mounting seat 1 during the operation of the dust collector, prevent the connection from being loose due to vibration, and facilitate the user to hold the upper shell 2 for dust collection operation. The lower shell 3 is mainly used for storing garbage, and needs to be disassembled and cleaned relatively frequently. The smaller adsorption force makes the lower shell 3 easier to disassemble, and the user can take it off for garbage pouring and cleaning without exerting too much effort. When the lower shell 3 is disassembled, one hand holds the upper shell 2, which can prevent the upper shell 2 from being disengaged from the mounting seat 1 before the lower shell 3. This scheme can be used simultaneously or alternatively with the pressing part 22 scheme.

[0033] As Figure 2 , 3As shown in Figure 4, the mounting base 1 has a filter seat 4 on the inner side of the annular wall 14. The side wall of the filter seat 4 has a second air outlet 41 communicating with the first air outlet 141. A filter screen is provided at the second air outlet 41. The upper end of the filter seat 4 is provided with a first inner magnetic suction member, and the mounting base 1 is provided with a second inner magnetic suction member 13. The first inner magnetic suction member and the second inner magnetic suction member 13 attract each other. During the operation of the vacuum cleaner, the garbage can be intercepted by the filter screen, ensuring that the garbage will not escape again, effectively avoiding secondary pollution to the surrounding environment. The magnetic suction method of fixing the filter seat 4 greatly simplifies the disassembly and installation process of the filter seat 4. When a large amount of garbage accumulates on the filter screen after a period of use and needs to be cleaned or replaced, the user only needs to overcome the attraction between the first inner magnetic suction member and the second inner magnetic suction member 13 to easily remove the filter seat 4. This process does not require any complicated tools or cumbersome disassembly steps, greatly improving the maintainability of the product and making it convenient for users to keep the vacuum cleaner at its best performance at all times.

[0034] like Figure 3 As shown, the mounting base 1 includes a mounting platform 15. A motor 151 and a battery 152 are located above the mounting platform 15, and a fan 153 connected to the motor 151 is located below the mounting platform 15. The battery 152 provides a stable power source for the motor 151, which, as the core power component of the vacuum cleaner, begins to operate at high speed after being powered on. The fan 153 connected below the mounting platform 15 rotates at high speed under the drive of the motor 151. According to the principles of fluid dynamics, the high-speed rotation of the fan 153 increases the surrounding airflow, thereby creating a negative pressure environment inside the vacuum cleaner.

[0035] like Figure 3 As shown, the lower housing 3 has a dust inlet 33 in the middle, and a brush body 34 is provided on the lower bottom surface of the lower housing 3. The brush body 34, with its soft yet resilient bristles, can penetrate deep into the fine crevices and uneven areas of the cleaning surface, loosening dust, debris, and other contaminants attached to these locations, making them easier to suck into the dust inlet 33. Simultaneously, the brush body 34 also provides a buffering effect when in contact with the surface, preventing scratches caused by direct friction between the bottom of the lower housing 3 and the cleaning surface.

[0036] In this embodiment, the magnetic attractor can be two magnets attracting each other, or one magnet attracting another magnetic metal such as iron. When the magnetic attractor is a magnetic metal, the magnetic metal can be integrally formed on the corresponding component. For example, if the mounting base 1 is made of iron, the magnetic metal can also be a separate component fixed to the plastic mounting base 1.

[0037] When the cleaner is started, the battery 152 supplies power to the motor 151, and the motor 151 rotates at high speed to drive the fan 153. The rotation of the fan 153 forms a negative pressure environment inside the cleaner. At this time, the dust inlet 33 in the middle of the lower shell 3 starts to play a role, and the outside air, which wraps up the garbage such as dust, debris, etc., is sucked into the lower shell 3 due to the negative pressure. The brush body 34 on the bottom surface of the lower shell 3 is in contact with the cleaning surface during the movement of the cleaner, and its soft bristles penetrate into the fine gap of the cleaning surface to loosen the stubborn dirt attached to it, making it easier for the garbage to be sucked into the dust inlet 33.

[0038] The air sucked into the lower shell 3 will pass through the second air outlet 41 on the side wall of the filter seat 4 and the first air outlet 141 on the ring wall 14 of the mounting seat 1 in turn. A filter screen is provided at the second air outlet 41, and when the air passes through, the fine mesh on the screen intercepts the garbage, and the purified air continues to be discharged through the first air outlet 141.

[0039] In terms of structural connection, the lower shell 3 is fixed on the mounting seat 1 by the first lower magnetic attraction member 31 on the bottom and the second lower magnetic attraction member 11 at the lower end of the mounting seat 1. The upper shell 2 is fixed by the first upper magnetic attraction member 21 on it and the second upper magnetic attraction member 12 on the mounting seat 1. In addition, when the pressing part 22 of the side wall of the upper shell 2 is pressed, its clamping position 23 is clamped with the mounting seat 1, further enhancing the stability of the connection between the upper shell 2 and the mounting seat 1. When disassembling the lower shell 3, the upper shell 2 will not be separated from the mounting seat 1 due to the double action of clamping and magnetic attraction of the pressing part 22. If you want to disassemble the upper shell 2, you only need to release the pressure on the pressing part 22, and the clamping position 23 will be separated from the clamping groove of the mounting seat 1 after the springback of the pressing part 22. After overcoming the magnetic attraction force, the upper shell 2 can be easily removed. The whole working process is efficient, stable and convenient to operate.
