DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0032] like Figures 1 to 7 As shown, the handheld vacuum cleaner provided in this embodiment mainly includes a suction pipe 1, a dust cup 2, a filter assembly, a fluid duct 3, a motor compartment 4, a motor assembly 400, a shell 10, a screen 6, a control button 7, a handle 8 and a power supply assembly 9.

[0033] In this embodiment, the dust cup 2 includes a cup body 200 and a dust cup bottom cover 210 movably connected to the bottom end surface of the cup body 200 .

[0034] Specifically, the rear end of the dust cup bottom cover 210 is hinged to the cup body 200, and the front end of the dust cup bottom cover 210 is connected to the bottom cover release assembly 211 on the cup body 200. When the bottom cover release assembly 211 is in a locked state, the dust cup bottom cover 210 is locked to the bottom end of the cup body 200. When the bottom cover release assembly 211 is in a non-locked state, the dust cup bottom cover 210 is separated from the bottom end of the cup body 200, and the dust cup bottom cover 210 moves toward the downward area with the hinged part as the axis, and the bottom end of the cup body 200 is in an open state.

[0035] Among them, a sealing ring 2101 is provided on the dust cup bottom cover 210.

[0036] The end of the suction tube 1 is communicated with the interior of the cup body 200 , and the filter assembly is located inside the cup body 200 .

[0037] Specifically, under the action of the negative pressure suction generated by the motor assembly 400, the suction pipe 1 guides the dirt fluid into the cup body 200, separates the dirt particles and the airflow in the dirt fluid through the filter assembly, and the separated dirt particles are placed in the first dust collecting chamber 209 or the second dust collecting chamber 2031 of the cup body 200. The airflow is guided to the position of the exhaust hole 11 under the guidance of the motor assembly 400, and then guided to the outside of the exhaust hole 11 through the exhaust hole 11.

[0038] In this embodiment, the filter assembly includes a support structure, a filter screen cover 201 , a plurality of cones 2020 , a detachable filter assembly 208 and a dust shielding ring plate 205 , and the plurality of cones 2020 and the detachable filter assembly 208 are sequentially located downstream of the filter screen cover 201 .

[0039] Specifically, the bracket structure includes a first bracket 202, a second bracket 203, a lower ring plate 204, an air guide plate 206 and an upper baffle 207. The lower ring plate 204 and the second bracket 203 are both surrounded by the outside of the first bracket 202, and the lower ring plate 204 is connected to the second bracket 203 and the first bracket 202 in sequence by screws. The upper baffle 207 and the air guide plate 206 are buckled on the top of the first bracket 202 in sequence, and a part of the air guide plate 206 is located inside the first bracket 202.

[0040] Furthermore, the second bracket 203 includes a first part and a second part which are arranged up and down, wherein the filter screen cover 201 is sleeved and fixed on the outside of the first part, and a first slot 2030 facing upward is provided on the first part.

[0041] The dust-blocking ring plate 205 is connected to the first bracket 202 and is thus placed inside the dust cup 2 , and at the same time divides the inside of the dust cup 2 into upper and lower filtering areas and a first dust collecting chamber 209 .

[0042] Further, the first bracket 202 includes an intermediate cavity plate 2023, a plurality of cones 2020 surrounding the outer side of the intermediate cavity plate 2023 and connected to the outer wall surface of the intermediate cavity plate 2023, and a lower edge plate 2022 of an annular structure connected to the outer wall surface of each cone 2020. The bottom end surface of the lower edge plate 2022 is located below the bottom end surface of the cone 2020. When the bottom end surface of the lower edge plate 2022 is embedded in the first slot 2030, the second bracket 203 surrounds the outer side of the first bracket 202, thereby forming a second dust collecting chamber 2031 in the lower area of the cone 2020 for collecting fine dirt particles separated by the cone 2020. The second dust collecting chamber 2031 is defined by the outer wall surface of the lower end portion of the intermediate cavity plate 2023 and the inner wall surface of the second portion of the second bracket 203.

[0043] Since the bottom end surface of the middle cavity 2024 abuts against the top end surface of the sealing ring 2101 and the bottom end surface of the second bracket 203 abuts against a part of the detachable filter assembly 208, it can be ensured that the dust is placed inside the second dust collecting cavity 2031.

[0044] An intermediate cavity 2024 for accommodating at least a portion of the detachable filter assembly 208 is formed inside the intermediate cavity plate 2023 .

[0045] A cone air inlet end 2021 is also provided on the side wall surface of the cone 2020 , and the fluid is guided to the interior of the cone 2020 through the cone air inlet end 2021 .

[0046] Specifically, the air guide plate 206 includes an annular hole a2061 formed on its surface, and a plurality of air guide tubes 2060 extending to the lower region of the air guide plate 206. The plurality of air guide tubes 2060 surround the outer side of the annular hole a2061, and each air guide tube 2060 is in communication with the air guide plate 206. When the air guide plate 206 is buckled onto the top of the first bracket 202, the annular hole a2061 is located above the middle cavity 2024, and the air guide tube 2060 is placed in the cone 2020 corresponding to the position thereof, so that the airflow separated by the cone 2020 is transferred to the downstream region thereof through the air guide tube 2060.

[0047] Specifically, the upper baffle 207 includes an annular hole b2070 opened on its surface. When the upper baffle 207 is set on the top of the air guide plate 206, the annular hole b2070 is located above the annular hole a2061, and the annular hole b2070 is connected to the interior of the intermediate cavity 2024 through the annular hole a2061.

[0048] In addition, when the upper baffle 207 is set on the top of the air guide plate 206, the upper baffle 207 forms a spacing channel with the air guide plate 206 through a plurality of longitudinal baffles arranged on its bottom end face, and the spacing channel forms an airflow channel. The airflow separated by the cone 2020 is guided into the airflow channel through the air guide pipe 2060, thereby entering the interior of the intermediate cavity 2024.

[0049] A first annular abutment portion 2071 extending downward is provided at the edge of the annular hole b2070 in the upper baffle 207, and a second annular abutment portion 2072 extending downward is also provided on the bottom end surface of the upper baffle 207. A supporting area for accommodating a portion of the detachable filter assembly 208 is formed between the first abutment portion 2071 and the second abutment portion 2072.

[0050] The first abutting portion 2071 , the second abutting portion 2072 and the abutting area form an assembly portion.

[0051] The support structure is composed of a first support 202, a second support 203, a lower ring plate 204, an air guide plate 206 and an upper baffle plate 207, making the support structure more compact.

[0052] Specifically, the detachable filter assembly 208 includes an upper soft rubber ring 2080, a filter body, a lower soft rubber ring 2083 and an end cap 2084. The top edge of the filter body is connected to the upper soft rubber ring 2080, the bottom edge of the filter body is connected to the end cap 2084, and the lower soft rubber ring 2083 is connected to the filter body and the end cap 2084 respectively, and surrounds the outside of the filter body and the end cap 2084.

[0053] The first protrusion 20801, the second protrusion 20802 and the third protrusion 20803 are arranged on the outer wall surface of the upper soft rubber ring 2080, and a slot for connecting with the filter body is arranged on the inner wall surface of the upper soft rubber ring 2080. When the detachable filter assembly 208 is placed inside the middle cavity 2024, a part of the upper soft rubber ring 2080 is placed in the abutment area, the top end surface of the upper soft rubber ring 2080 abuts against the bottom end surface of the first abutting portion 2071, the first protrusion 20801 and the second protrusion 20802 abut against the inner wall surface of the second abutting portion 2072, and the third protrusion 20803 abuts against the bottom end surface of the second abutting portion 2072.

[0054] A portion of the end cap 2084 is placed in the filter body so that the bottom end surface of the filter body forms a closed structure.

[0055] A fourth protrusion 20830 and a fifth protrusion 20831 are provided on the outer wall surface of the lower soft rubber ring 2083, wherein the end of the fourth protrusion 20830 abuts against the inner wall surface of the middle cavity 2024, and the upper end surface of the fifth protrusion 20831 abuts against the bottom end of the middle cavity 2024, so that the bottom of the middle cavity 2024 forms a sealed state, and the fluid guided into the middle cavity 2024 can only enter the filter body and filter the fluid again.

[0056] A handle portion 20840 is also provided on the end cover 2084 , and the bottom end surface of the handle portion 20840 is located in the lower area of the end cover 2084 and abuts against the inner wall surface of the dust cup bottom cover 210 .

[0057] When the detachable filter assembly 208 is placed inside the middle cavity 2024 and the dust cup bottom cover 210 is in a closed state, the top of the detachable filter assembly 208 is located in the assembly portion of the upper area of the middle cavity 2024. Specifically, the first protrusion 20801 and the second protrusion 20802 in the upper soft rubber ring 2080 are both placed in the abutment area, and the third protrusion 20803 abuts against the bottom end face of the second abutment portion 2072. The bottom end face of the end cover 2084 abuts against the top end face of the sealing ring 2101, and the bottom end face of the handheld portion 20840 abuts against the top end face of the dust cup bottom cover 210, thereby sandwiching the detachable filter assembly 208 between the upper baffle 207 and the dust cup bottom cover 210.

[0058] The top of the detachable filter assembly is located in the upper area of the middle cavity. The extrusion pressure applied to the detachable filter assembly by the dust cup bottom cover makes the top of the detachable filter assembly be located in the upper area of the middle cavity, and a part of the top of the detachable filter assembly is deformed under the action of the extrusion force, thereby being in close contact with the upper baffle, thereby avoiding displacement and shaking of the detachable filter assembly in the middle cavity, thereby improving the assembly performance of the detachable filter assembly.

[0059] The squeezing force applied to the detachable filter assembly by the dust cup bottom cover can avoid the formation of a gap between the top of the detachable filter assembly and the upper baffle, ensuring that the airflow separated by the detachable filter assembly can only be guided to its downstream area through the annular hole b in the upper baffle.

[0060] In this embodiment, the filter body is composed of a filter support 2081 and a filter layer 2082 surrounding the outside of the filter support 2081 .

[0061] Among them, the filter layer 2082 is preferably a filter sponge or a filter Hepa.

[0062] In this embodiment, the fluid air duct 3 includes a transverse air duct 301 and a longitudinal air duct 302 that are connected to each other. The connection between the transverse air duct 301 and the longitudinal air duct 302 is an arc-shaped transition, which is convenient for guiding the airflow into the longitudinal air duct 302.

[0063] Among them, the transverse air duct 301 includes an air inlet end 300, which is located above the dust cup 2 and connected to the dust cup 2, and corresponds to the position of the annular hole b2070, so that the air flow separated by the detachable filter assembly 208 enters the transverse air duct 301 through the annular hole b2070 and the air inlet end 300.

[0064] The connection between the transverse air duct 301 and the longitudinal air duct 302 is an arc-shaped transition, which is convenient for guiding the airflow into the longitudinal air duct 302 .

[0065] Among them, the longitudinal air duct 302 includes an air outlet end 303, which is connected to the motor assembly 400 in the motor compartment 4 to guide the airflow to the interior of the motor assembly 400, thereby guiding the airflow to the outside of the vacuum cleaner through the motor assembly 400 and the air outlet filter component 5 and the exhaust hole 11 in the shell 10.

[0066] In this embodiment, the motor compartment 4 is fixed on the top end surface of the transverse air duct 301 in a horizontal manner.

[0067] The bottom end surface of the motor bin 4 is connected to the top end surface of the transverse air duct 301 , thereby supporting the motor bin 4 on the top of the transverse air duct 301 .

[0068] The motor assembly 400 is placed in the motor compartment 4 in a horizontal manner, and the horizontal axis of the motor assembly 400 is arranged parallel to the suction axis of the suction pipe 1 .

[0069] By adopting this method, compared with the design in the prior art in which the motor assembly is vertically arranged on the top of the dust cup, the utility model can reduce the height of the vacuum cleaner in the longitudinal vertical direction, making the connection structure between the motor compartment 4 and the dust cup 2 more compact and avoiding waste of space.

[0070] In addition, the motor assembly 400 is placed inside the motor compartment 4 along the transverse axis, so that the air outlet end 303 of the motor assembly 400 is positioned toward the exhaust hole 11 provided on the shell 10, so that the fluid discharged from the air outlet end 303 can be guided to the exhaust hole 11 along the transverse axis, thereby quickly discharging the fluid to the outside of the vacuum cleaner.

[0071] The above is only a preferred embodiment of the utility model, which is only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences can be made within the spirit and scope defined by the claims of the utility model, but they will all fall within the scope of protection of the utility model.
