Referring to fig. 1, in one embodiment of the present invention, a vacuum cleaner is provided, which includes a main body (not shown) and a dust cup device 100. The dust cup device 100 is connected with the main body, the main body comprises a shell, a motor and an impeller, the motor and the impeller are contained in the shell, the impeller is connected with a driving shaft of the motor, and the dust cup device 100 is connected with the shell. In the dust collection process, the driving shaft of the motor rotates to drive the impeller to rotate to generate negative pressure, external dust-carrying gas is sucked into the dust cup device 100 under the action of the negative pressure, the dust-carrying gas entering the dust cup device 100 forms rotating airflow under the action of cyclone generated by the motor, and gas-dust separation is realized under the action of centrifugal force.
Referring to fig. 1, 2 and 3, the dirt cup device 100 includes a dirt cup 10, a filter screen 20 and a separating cone 30. An air inlet 12 is arranged on the circumferential side wall of the dust cup 10. The filter screen 20 is disposed in the dust cup 10. The separation cone 30 is disposed in the filter screen 20. The outer wall of the filter screen 20 and the inner wall of the dust cup 10 define a dust collecting chamber a. Under the negative pressure effect generated by the rotation of the impeller driven by the motor, the dust-carrying airflow enters the dust collection cavity a through the air inlet 12, and forms a rotating airflow rotating around the filter screen cover 20 under the cyclone effect generated by the motor, the dust with larger mass collides with the inner wall of the dust cup 10 under the action of centrifugal force and falls, and the rest dust and dirt enters the separation cone 30 through the filter screen cover 20 along with the airflow, and is separated again in the separation cone 30. That is, the filter screen 20 performs a first stage of dust-air separation on the dust-laden air flow entering the dust cup 10. The separation cone 30 performs a second stage of dust-gas separation on the dusty gas stream.
It should be noted that the dirt cup apparatus 100 can include one or more separation cones 30. One or more separation cones 30 are disposed within the filter screen 20. The number of the separation cones 30 may be designed according to specific situations, and is not limited herein. The dust cup apparatus 100 will be described below as including a separation cone 30.
Specifically, the air inlet 12 penetrates through the circumferential side wall of the dust cup 10 in a tangential direction, so that the air inlet 12 has an effect of changing the direction of the dust-laden air flow, and when the dust-laden air flow enters the dust collection cavity a through the air inlet 12, the direction of the dust-laden air flow is changed to the tangential direction along the dust cup 10, which is beneficial to forming a rotating air flow.
Further, the dirt cup assembly 100 also includes a filter element 40. The dirt cup 10 has an opening 14 at the top end. The top end of the filter screen cover 20 is provided with an opening 24. The filter screen 20 is assembled in the dust cup 10 through the opening 14 of the dust cup 10, and the circumferential edge of the top end of the filter screen 20 is in sealing fit with the inner wall of the dust cup 10 to form the dust collection cavity a. The separation cone 30 is mounted in the filter screen 20 through the opening 24 at the top end of the filter screen 20. The filter member 40 is sealingly disposed at the opening 14 at the top end of the dirt cup 10 to filter fine dirt remaining in the airflow discharged from the top end of the separation cone 30. That is, filter element 40 provides a third stage of gas-dust separation of the gas stream. Alternatively, the filter element 40 may be filter cotton. The filter member 40 is not limited to the filter cotton, and other materials that can meet the filtering requirement may be used, and is not limited herein.
It should be noted that the assembly method of the dust cup 10, the filter screen 20 and the separation cone 30 is not limited to the above assembly method, and other methods may be used as long as they can achieve the first-stage dust-air separation after the dust-laden air flow enters the dust collection chamber a, and then enters the separation cone 30 from the filter screen 20 to perform the second-stage dust-air separation, and the air flow discharged from the top end of the separation cone 30 passes through the filter element 40 to perform the third-stage dust-air separation, which is not limited herein.
Further, the bottom end of the separation cone 30 penetrates through the bottom end of the filter screen 20 and is communicated with the outside of the dust cup 10, and dust and dirt generated by separation of the separation cone 30 can be discharged through the bottom end of the separation cone.
Referring to fig. 3 and 4, the separation cone 30 has an inner cavity b, and an air inlet 312 (see fig. 4), an air outlet 314 and a dust collecting port 316 communicating with the inner cavity b. Air inlets 312 are located on the circumferential sidewall of the tip of separation cone 30. The exhaust port 314 and the dust collecting port 316 are respectively located at the top end and the bottom end of the separation cone 30 in the axial direction.
The separation cone 30 includes at least two reducer sections 32 arranged along an axial direction thereof. Each of the variable diameter sections 32 has an inner diameter gradually decreasing in a direction from the top end of the separation cone 30 toward the bottom end.
The dust-laden air flow of the separation cone 30 enters the inner cavity b of the separation cone 30 through the air inlet 312 and rotates along the circumferential direction of the separation cone 30 to form a downward-moving rotating air flow. After the downward-moving rotating airflow enters the reducing sections 32, dust and dirt sequentially collide with the circumferential side walls of the reducing sections 32 under the action of centrifugal force, and then fall downwards and are collected from the dust collecting port 316. At the same time, the air flow is gradually reflected by the circumferential side walls of the respective reducer sections 32 to form a whirling air flow moving upward in the middle of the inner cavity b, and further from the exhaust port 314. So, separation awl 30 sets up two sections at least reducing section 32, carries out the dirt gas separation under the effect of centrifugal force when taking the dirt circulation to pass through two sections at least reducing section 32, carries out twice dirt gas separation at least to the air current promptly to be favorable to improving dirt gas separation effect, and then avoid influencing motor life-span and environment.
In an embodiment of the present invention, the separation cone 30 further comprises a first straight wall section 34. Between each two adjacent variable diameter sections 32 there is a first straight wall section 34. The first straight wall section 34 has a constant inner diameter in a direction from the top end to the bottom end of the separation cone 30. So, the dust-carrying air current gets into the first straight wall section 34 adjacent with this reducing section 32 after passing reducing section 32, because the internal diameter of first straight wall section 34 keeps unchangeable, the air current is steady gradually, for getting into reducing section 32 once more and carrying out the dust and gas separation and prepare, avoids the air current disorder, is favorable to improving dust and gas separation effect.
In the specific embodiment, the circumferential inner wall of each variable-diameter section 32 and the adjacent first straight wall section 34 is smoothly transited, so that the influence on the air flow is reduced, and the dust-gas separation effect is favorably ensured.
In one embodiment, the separation cone 30 further includes a second straight wall section 36 at the top end of the separation cone 30. The second straight wall section 36 has a constant inner diameter in the direction from the top end to the bottom end of the separation cone 30. The inlet port 312 opens into the second straight wall section 36. Thus, the air inlet 312 is opened on the second straight wall section 36, which is beneficial to forming a stable downward moving rotating air flow, and improves the dust-air separation effect.
Further, the air inlet 312 tangentially penetrates the circumferential inner wall of the second straight wall section 36, thereby facilitating the formation of a rotating air flow.
Further, the cross section of the air inlet 312 is rectangular, and the length direction of the cross section is parallel to the axial direction of the separation cone 30. So for the air current that gets into inner chamber b distributes along the circumference inner wall of second straight wall section 36, avoids the air current disorder, is favorable to forming stable rotatory air current.
In particular embodiments, the circumferential inner wall of the second straight wall section 36 and the reducer section 32 adjacent thereto smoothly transitions so as to avoid affecting the rotating gas flow.
In one embodiment, the reducer section 32 comprises two sections. The second straight wall section 36, one of the two variable diameter sections 32, the first straight wall section 34, and the other of the two variable diameter sections 32 are sequentially arranged from the top end to the bottom end of the separation cone 30. Therefore, the dust-gas separation is sequentially carried out on the dust-carrying airflow entering the inner cavity b through the two sections of the reducing sections 32, and the dust-gas separation effect is favorably improved.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
