Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a hand-push vacuum cleaner. Background Art

[0002] A hand-push vacuum cleaner is a cleaning device suitable for cleaning floors, carpets and other surfaces, and is commonly found in commercial environments and industrial sites. When the hand-push vacuum cleaner moves on the surface to be cleaned and performs vacuuming operations, it sucks in an airflow mixed with particles and filters the particles. The filtered particles are collected in a dust collecting part or a dust bag, and the filtered air is discharged into the external environment. Since there are often some ferromagnetic particles such as nails, screws, and iron filings on the surface to be cleaned, these ferromagnetic particles are sucked into the vacuum cleaner with the airflow. These sharp and hard ferromagnetic particles are easily stirred and collided in the stirring chamber of the vacuum cleaner, causing damage to the shell, dust bag and negative pressure source, which brings trouble to the cleaning operation. Therefore, the existing hand-push vacuum cleaners are not safe and reliable enough, and there is an urgent need for a hand-push vacuum cleaner that can filter out ferromagnetic particles when vacuuming.

DETAILED DESCRIPTION

[0028] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction on the technical solution of the utility model.

[0029] according to Figure 1 and Figure 6As shown, one embodiment of the utility model provides a hand-push vacuum cleaner 100, which includes a cleaning base 10 and a hand-push part 20. The cleaning base 10 includes a shell 11, a roller brush 16, a dust collecting part 17 and a negative pressure source 18. A front wheel 14 is installed on the front side of the bottom of the shell 11, and a rear wheel 15 is installed on the rear side of the bottom of the shell 11. A dust suction part 12 is provided on the front side of the front wheel 14 at the bottom of the shell 11, and the dust suction part 12 includes a suction port 121 for sucking the dust-containing airflow on the surface to be cleaned. In other embodiments, the dust suction part 12 may also include a suction nozzle for sucking the dust-containing airflow on the surface to be cleaned, and there is no specific limitation. A stirring chamber 111 is defined inside the shell 11, which is connected to the suction port 121 by airflow, and the suction port 121 is formed below the stirring chamber 111. The roller brush 16 is installed in the stirring chamber 111, and is connected to the roller brush 16 by a driving module (not shown in the figure) installed inside the housing 11 to drive the roller brush 16 to make a circular motion around an axis, so as to clean the dust attached to the surface to be cleaned, and improve the dust suction part 12 to pick up dust particles. The dust collecting part 17 is installed inside the housing 11 and is connected to the stirring chamber 111 through a section of airflow duct 19. The airflow duct 19 is a section of hard pipe. In other embodiments, the airflow duct 19 can also be a hose, which is not specifically limited. The negative pressure source 18 is installed inside the housing 11 and is connected to the dust collecting part 17. The dust collecting part 17 includes a dust collecting box, a filter assembly (not shown in the figure) arranged inside the dust collecting box and used to filter dust particles, and the filter assembly is a dust bag filter. In other embodiments, the dust collecting part 17 can also include a dust collecting bag, and the filter assembly can also be a HEPA filter, which is not specifically limited. The negative pressure source 18 generates negative pressure airflow when working. The negative pressure source 18 is a suction motor. In other embodiments, the negative pressure source 18 may also be a negative pressure pump, which is not specifically limited.

[0030] When the hand-push vacuum cleaner 100 is working, the dust-laden airflow on the surface to be cleaned is sucked into the mixing chamber 111 from the suction port 121, and is sent to the dust collecting section 17 for filtration through the airflow duct 19. The dust particles remain in the dust collecting section 17, and the air is sucked away by the negative pressure source 18 and discharged into the external environment.

[0031] according to Figure 1 and Figure 4 As shown, a receiving cavity 112 is defined at the top of the shell 11, and the dust collecting part 17 is detachably arranged in the receiving cavity 112. The user can easily remove the dust collecting part 17 from the shell 11 to dump the dust.

[0032] One end of the hand push part 20 is connected to the housing 11, and the other end of the hand push part 20 is provided with a handle 21 for the user to hold. The user can hold the handle 21 and push the cleaning base 10 to move from back to front on the surface to be cleaned and perform vacuuming. Specifically, the hand push part 20 includes two support arms 22 and a U-shaped arm 23, one end of the two support arms 22 is connected to the housing 11, and the other end of the two support arms 22 is connected to the two ends of the U-shaped arm 23, and the U-shaped arm 23 is bent from the connection with the two support arms 22 toward the front side to form the handle 21.

[0033] In particular, since the dust particles on the surface to be cleaned may contain some ferromagnetic particles, such as iron filings, screws, gaskets, etc., these hard and sharp ferromagnetic particles, once sucked into the suction port 121 and stirred by the roller brush 16 in the stirring chamber 111, may easily cause damage to the dust suction part 12 of the hand-push vacuum cleaner 100. In mild cases, the suction port 121 may be broken. In severe cases, multiple components inside the shell 11 (such as the dust collecting part 17 and the negative pressure source 18) may be damaged to varying degrees, causing trouble for the user's cleaning operation.

[0034] according to Figure 1 and Figure 2 As shown, in order to solve the above problems, the hand-push vacuum cleaner 100 includes an electromagnet adsorbing member 30, which is arranged on the housing 11 and located at the front side of the dust suction part 12. The electromagnet adsorbing member 30 is configured to generate magnetic force to adsorb ferromagnetic particles in the dust-laden airflow when powered on and demagnetize when powered off. The electromagnet adsorbing member 30 adsorbs and filters out the ferromagnetic particles before the dust-laden airflow enters the hand-push vacuum cleaner 100, and when the electromagnet adsorbing member 30 is powered off and demagnetized, the adsorbed ferromagnetic particles can fall off.

[0035] according to Figure 4 and Figure 5 As shown, the hand-push vacuum cleaner 100 further includes a controller 40, which is connected to the mains via a wire with an electric plug. The controller 40 is control-connected to the electromagnet adsorbing member 30 and is configured to control the power on and off of the electromagnet adsorbing member 30. Specifically, the controller 40 includes a key switch 41, which is connected to the electromagnet adsorbing member 30 via a line, and the user can control the power on and off of the electromagnet adsorbing member 30 by operating the key switch 41.

[0036] To facilitate the user to operate the controller 40 when holding the handle 21 and pushing the vacuum cleaner forward, the controller 40 is disposed on the hand-pushing portion 20 and located at the lower side of the handle 21. In other embodiments, the controller 40 may also be disposed on the cleaning base 10, without specific limitation.

[0037] according to Figure 8 and Fig. 9 As shown, when the user pushes the hand-push vacuum cleaner 100 to move from back to front on the surface to be cleaned and performs vacuuming, the user operates to turn on the key switch 41, so that the electromagnet adsorbing member 30 is powered on and the ferromagnetic particles in the dust-laden airflow on the surface to be cleaned are adsorbed and filtered. After the cleaning operation is completed, the user operates to turn off the key switch 41, so that the electromagnet adsorbing member 30 is powered off and the ferromagnetic particles adsorbed on the front side of the housing 11 fall off. In other embodiments, a relay may also be provided between the controller 40 and the electromagnet adsorbing member 30, the relay and the electromagnet adsorbing member 30 are connected by a wire, the relay and the controller 40 are connected by a control line, and the controller 40 is constructed to control the opening and closing of the relay to control the power on and off of the electromagnet adsorbing member, without specific limitation.

[0038] When the cleaning base 10 moves on the surface to be cleaned and sucks in the dust-containing airflow mixed with ferromagnetic particles through the dust suction part 12, the dust-containing airflow first passes through the electromagnet adsorption part 30. The electromagnet adsorption part 30 can generate magnetic force when powered on to adsorb the ferromagnetic particles in the dust-containing airflow. Therefore, when the hand-push vacuum cleaner 100 is vacuuming, the ferromagnetic particles in the dust-containing airflow are adsorbed and filtered out in advance, thereby preventing these ferromagnetic particles from entering the vacuum cleaner, which is safer and more reliable.

[0039] according to Figure 2 As shown, a receiving groove 13 is provided on the front surface of the housing 11 of the cleaning base 10, and the electromagnet adsorbing member 30 is provided in the receiving groove 13. The notch of the receiving groove 13 is arranged upward. In other embodiments, in order to facilitate the installation of the electromagnet adsorbing member 30, the notch of the receiving groove 13 can also be arranged forward or downward or arranged at an angle to the horizontal plane, which is not specifically limited.

[0040] according to Figure 3 and Figure 7 As shown, in order to facilitate the removal of the electromagnet adsorbing part 30, a plurality of hollow holes 131 are provided at the bottom of the shell 11. The plurality of hollow holes 131 are constructed so that the user can insert his fingers into the hollow holes 131 from the bottom of the shell 11 upward to buckle the electromagnet adsorbing part 30 out of the accommodating groove 13, without any specific limitation.

[0041] according to Figure 1 and Figure 4As shown, in order to enhance the magnetic adsorption effect, the electromagnet adsorbing member 30 extends along the length direction of the dust suction part 12, so that the electromagnet adsorbing member 30 covers the front area of ​​the suction port 121. In this way, when the suction port 121 of the dust suction part 12 absorbs the dust-laden airflow on the surface to be cleaned, the electromagnet adsorbing member 30 can adsorb the ferromagnetic particles entering the suction port 121 from any direction. In other embodiments, the hand-push vacuum cleaner 100 may also include a plurality of electromagnet adsorbing members 30, and the plurality of electromagnet adsorbing members 30 are arranged at intervals along the length direction of the dust suction part 12, without specific limitation.

[0042] The technical scope of the present invention is not limited to the contents in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
