An air purifier

Abstract

The present invention provides an air purifier, in which a fan moves synchronously with a first shell, and a first driving member and a second driving member are provided so that a filter assembly and a heating assembly can form a fan channel for the fan to pass through. The pusher drives the first shell and the fan to move toward the second shell, and when moving to the purification position, the filter assembly and the heating assembly will enter a non-working state, and the entire device will only perform electrical purification operations at this time. And because the filter assembly and the heating assembly have formed a fan channel for the outside wind to enter at this time, the amount of wind acting on the heating assembly will be greatly reduced, thereby effectively avoiding the pollution of the heating assembly by the wind. Since the first shell can move in the vertical direction relative to the second, when the air purifier needs to be stored, it is sufficient to control the movement between the first shell to the purification position. At this time, the overall height of the air purifier will be reduced, so that it is easy to store.

Description

Technical Field

[0001] The present invention relates to the technical field of air purifiers, and in particular to an air purifier capable of achieving height adjustment. Background Art

[0002] Air purifiers are very common household appliances in daily life. With the development, the functions that air purifiers can achieve are increasing.

[0003] In the prior art, the air purification operation is achieved through the electric purification module, and the air sterilization operation is achieved through the filter and heating component. The above-mentioned multiple modules are usually started at the same time, that is, the air purifier can achieve the functions of purification and sterilization at the same time. However, for some areas and some time periods, only the purification operation can be performed without the additional sterilization operation, and the sterilization process requires more energy, resulting in a waste of energy.

[0004] To this end, technicians have developed an air purifier that can control the start and stop of different modules such as the heating module and the electric purification module by inserting a controller. For example, when only the electric purification module is needed, only the electric purification module is controlled to start, and the heating module is not started. At that time, because the wind needs to act on the electric purification module first, and then on the heating module, even if the heating module is not started, the outside wind will continue to act on the heating module, thereby polluting the heating module, and then affecting the life of the air purifier. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that when the air purifier is only performing a purification operation, the external wind still pollutes the heating module.

[0006] To this end, the present invention provides an air purifier, comprising: a housing, comprising a first housing and a second housing nested with each other; a fan, disposed in the first housing and moving synchronously with the first housing;

[0007] A filter assembly and a heating assembly, wherein the heating assembly is arranged on a side of the filter assembly away from the fan, the filter assembly is provided with a first driving member, and the heating assembly is provided with a second driving member, the first driving member and the second driving member are respectively adapted to drive the filter assembly and the heating assembly to rotate, so as to form a fan channel for the fan to enter the second housing; a pushing member is arranged between the first housing and the second housing, and is adapted to push the first housing to move relative to the second housing;

[0008] The filter assembly and the heating assembly have a non-operating state when the fan enters the fan channel, and a working state when the fan leaves the fan channel.

[0009] In the air purifier provided by the present invention, the filter assembly includes a first filter and a second filter arranged relatively to each other, and the first driving member includes a first motor and a second motor respectively connected to the first filter and the second filter.

[0010] In the air purifier provided by the present invention, the heating assembly includes a first heating element and a second heating element that are arranged opposite to each other, and the second driving element includes a third motor and a fourth motor that are respectively connected to the first heating element and the second heating element.

[0011] The air purifier provided by the present invention, the pushing member includes: a lifting motor, which is arranged on one of the first shell and the second shell; a driving gear, which is connected to the lifting motor; and a rack, which is arranged on the other of the first shell and the second shell, and the driving gear is suitable for acting on the rack.

[0012] In the air purifier provided by the present invention, the inner wall of the first shell is nested on the outer wall of the second shell.

[0013] In the air purifier provided by the present invention, the bottom surface of the first shell extends to a position below the top surface of the second shell, and the first shell and the second shell are arranged in contact with each other at one side opposite to the motor.

[0014] The air purifier provided by the present invention further includes a position sensor, which is arranged on the housing and connected to the controller. The position sensor includes a first position sensor and a second position sensor arranged along the height direction, the first position sensor corresponds to the sterilization position, and the second position sensor corresponds to the purification position.

[0015] The air purifier provided by the present invention further includes: an electric purification component, which is arranged on a side of the heating component away from the filter component.

[0016] The technical solution of the present invention has the following advantages:

[0017] 1. The air purifier provided by the present invention comprises: a shell, comprising a first shell and a second shell nested in each other; a fan, which is arranged in the first shell and moves synchronously with the first shell; a filter assembly and a heating assembly, wherein the heating assembly is arranged on a side of the filter assembly away from the fan, the filter assembly is provided with a first driving member, and the heating assembly is provided with a second driving member, the first driving member and the second driving member are respectively suitable for driving the filter assembly and the heating assembly to rotate, so as to form a fan channel for the fan to enter the second shell; a pushing member, which is arranged between the first shell and the second shell, and is suitable for pushing the first shell to move relative to the second shell, the first shell having a sterilization position and a purification position driven by the pushing member; the filter assembly and the heating assembly have a non-working state when the fan enters the fan channel, and a working state when the fan leaves the fan channel.

[0018] In the present invention, the fan moves synchronously with the first housing, and by providing a first driving member and a second driving member, the filter assembly and the heating assembly can form a fan channel for the fan to pass through. The pusher drives the first housing and the fan to move toward the second housing. When moving to the purification position, the filter assembly and the heating assembly will enter a non-working state, and the entire device will only perform electrical purification operations. And because the filter assembly and the heating assembly have formed a fan channel for the outside wind to enter, the amount of wind acting on the heating assembly will be greatly reduced, thereby effectively avoiding the pollution of the heating assembly by the wind.

[0019] At the same time, in the present invention, since the first shell can move in the vertical direction relative to the second shell, when the air purifier needs to be stored, it is sufficient to control the first shell to move to the purification position.

[0021] By disassembling the filter assembly into the first filter and the second filter, and arranging the first motor and the second motor on the first filter and the second filter respectively, the travel of the first filter and the second filter during the relative opening and closing process is shortened, thereby reducing the height of the entire air purifier. At the same time, by splitting into the first filter and the second filter, the load of the first motor and the second motor can be effectively reduced, thereby reducing the overall efficacy.

[0022] 3. In the air purifier provided by the present invention, the bottom surface of the first shell extends to a position below the top surface of the second shell, and the first shell and the second shell are arranged in contact with each other on one side opposite to the motor.

[0023] The first shell and one side of the second shell are pressed against each other to form a stable contact surface, thereby achieving a stable lifting action of the first shell relative to the second shell and preventing the first shell from tilting relative to the second shell.

[0033] Example

[0034] This embodiment provides an air purifier, comprising:

[0035] The housing comprises a first housing 1 and a second housing 2 which are nested with each other. Figure 1 As shown, the first housing 1 is arranged at an upper position, and the second housing 2 is arranged at a lower position of the first housing 1. At the same time, an air outlet 15 is arranged on the first housing 1, and an air inlet is arranged on the second housing 2. Wind enters the housing through the air inlet and flows out from the air outlet 15;

[0036] The fan 3 is disposed in the first housing 1 and moves synchronously with the first housing 1. Specifically, the fan 3 is disposed on the top wall of the first housing 1 and is disposed opposite to the air outlet 15;

[0037] A filter assembly and a heating assembly, wherein the heating assembly is arranged on a side of the filter assembly away from the fan 3, the filter assembly is provided with a first driving member, and the heating assembly is provided with a second driving member, the first driving member and the second driving member are respectively adapted to drive the filter assembly and the heating assembly to rotate, so as to form a fan channel for the fan 3 to enter the second housing 2;

[0038] Specifically, the function of the filter assembly itself is to filter pollutants in the wind. The heating assembly is arranged below the filter assembly to heat the filter assembly and thereby kill bacteria, viruses and other substances adhering to the filter assembly.

[0039] In this embodiment, the filter assembly and the heating assembly can be arranged in an integral shape or in a separate shape. When an integral shape is adopted, a first driving member is arranged at one end of the filter assembly, and the first driving member can be arranged on the left side of the filter assembly or on the right side of the filter assembly. In this case, the first driving member can drive the filter assembly to rotate within a certain angle range, such as within the range of [0,90°]. Similarly, when the heating assembly is arranged in an integral shape, a second driving member is arranged at one end of the heating assembly, and the second driving member can also be arranged on the left side or the right side of the heating assembly. Similarly, the heating assembly itself can rotate within a certain angle range, such as within the range of [0,90°].

[0040] Specifically, when the filter assembly and the heating assembly are arranged in an integrated form, the distance between the filter assembly and the heating assembly can be adjusted according to the rotation direction of the filter assembly and the heating assembly. When the filter assembly and the heating assembly rotate in the same direction, such as when both rotate clockwise or counterclockwise, the vertical distance between the two will be greater than the length of the heating assembly; when the filter assembly and the heating assembly rotate in opposite directions, it is not necessary to limit the distance between the filter assembly and the heating assembly;

[0041] As a preferred embodiment, the filter assembly and the heating assembly can be provided in a separate manner, or both the filter assembly and the heating assembly can be provided in a separate manner. Figure 1 As shown, the filter assembly includes a first filter 4 and a second filter 5 arranged opposite to each other, and the first driving member includes a first motor 6 and a second motor 7 connected to the first filter 4 and the second filter 5 respectively.

[0042] Correspondingly, the heating component can be arranged in an integrated form or in a split form. When a split form is adopted, the heating component includes a first heating element 8 and a second heating element 9 arranged opposite to each other, and the second driving element includes a third motor 10 and a fourth motor 11 respectively connected to the first heating element 8 and the second heating element 9.

[0043] In this embodiment, both the first driving member and the second driving member are motors.

[0044] A pushing member, disposed between the first shell 1 and the second shell 2, and adapted to push the first shell 1 to move relative to the second shell 2;

[0045] The filter assembly and the heating assembly have a non-operating state when the fan 3 enters the fan channel, and a working state when leaving the fan channel.

[0046] In this embodiment, the pusher includes: a lifting motor 12, which is arranged on one of the first housing 1 and the second housing 2; a driving gear connected to the lifting motor; a rack 13, which is arranged on the other of the first housing 1 and the second housing 2, and the driving gear is suitable for acting on the rack 13. As a variation, the pusher can also be other structures, such as a combination of a worm gear and a motor, as long as it can drive the first housing to move relative to the second housing.

[0047] As a preferred embodiment, the inner wall of the first housing 1 is nested on the outer wall of the second housing 2. Correspondingly, the bottom surface of the first housing 1 extends to a position below the top surface of the second housing 2, and the first housing 1 and the second housing 2 are arranged against each other on the sides opposite to the motor.

[0048] As a variation, the outer wall of the first shell 1 can be nested on the inner wall of the second shell 2. Correspondingly, the motor is set on the inner wall of the second shell 2, and the rack 13 is set on the outer wall of the first shell 1, and the first shell 1 is driven to move in the height direction by starting the motor. Similarly, at this time, the bottom surface of the first shell 1 needs to extend to the position below the top surface of the second shell 2, and the outer wall of the first shell 1 is against the inner wall position of the second shell 2.

[0049] In this embodiment, a controller is also provided, which is communicatively connected with the first driving member, the second driving member, the pushing member, the filter assembly and the heating assembly, and is suitable for controlling the first driving member and the second driving member to form the fan channel and control the filter assembly and the heating assembly to stop when the pushing member is started.

[0050] By setting the controller, at least one component can be started or stopped when other components are started.

[0051] The air purifier provided in this embodiment further includes a position sensor, which is arranged on the shell and connected to the controller.

[0052] Specifically, the position sensor includes a first position sensor and a second position sensor arranged along the height direction, the first position sensor corresponds to the sterilization position, and the second position sensor corresponds to the purification position. By setting the position sensor, when the first shell 1 moves to a certain set position relative to the second shell 2, the controller will control the motor to stop moving, thereby preventing the first shell 1 from moving excessively relative to the second shell 2.

[0053] In this embodiment, the first position sensor is disposed below the second position sensor. When the first shell 1 moves downward and triggers the first position sensor, the first shell 1 stops moving.

[0054] In this embodiment, an alarm device is also provided, and when the first housing 1 moves to a set position, the alarm device will be activated, thereby reminding the user. Specifically, the alarm device can be a buzzer or a warning light.

[0055] The air purifier provided in this embodiment further includes: an electric purification component 14, which is arranged on a side of the heating component away from the filter component. Figure 1 As shown, the electric purification component 14 is arranged inside the housing and below the heating assembly. The electric purification component 14 itself can directly adopt a plasma generating device.

[0056] The working process of the air purifier provided in this embodiment is as follows:

[0057] Mode 1: Air purification only

[0058] The controller controls the motor of the pusher to start, and the first shell 1 will move downward. At this time, the first motor 6 and the second motor 7 will drive the first filter 4 and the second filter 5 to rotate, the first filter 4 will rotate counterclockwise, and the second filter 5 will rotate clockwise. At the same time, the third motor 10 and the fourth motor 11 will drive the first heating element 8 and the second heating element 9 to rotate, and the third motor 10 will rotate clockwise, and the fourth motor 11 will rotate clockwise. Through the above movement, a fan channel will be formed, and the fan 3 will move downward in the fan channel;

[0059] At the same time, the controller will control the filter assembly and the heating assembly to stop, and control the fan 3 and the electric purification component 14 to start. At this time, the entire control purifier will only perform the electric purification operation, but not the disinfection operation. When the first shell 1 moves downward to the preset position, the position sensor will be triggered, and the position sensor will transmit the signal to the controller. The controller will control the motor to stop moving, thereby stabilizing the first shell 1 at a specific position. At this time, the overall height of the air purifier will be reduced. At this time, if Figure 2 shown.

[0060] Mode 2: Simultaneous air purification and sterilization operations

[0061] When purification and sterilization operations are required at the same time, the controller controls the motor of the pusher to start, and controls the filter assembly, heating assembly and electric purification assembly to start. At this time, the first shell 1 will move upward relative to the second shell 2. When reaching the preset position, the first position sensor will be triggered. At this time, the first position sensor will control the motor to stop moving, and the overall height of the air purifier will increase. At this time, Figure 1 shown.

[0062] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
