Detailed implementation manners

[0042] The following will specifically describe the preferred embodiments of the present invention with reference to the accompanying drawings. The accompanying drawings form a part of the present invention and are used together with the embodiments of the present invention to explain the principle of the present invention, rather than to limit the scope of the present invention.

[0043] In the description of the embodiments of the present invention, it should be noted that unless otherwise clearly specified and limited, the term "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0044] The terms "top", "bottom", "above", "below", and "on" used throughout the description are relative positions with respect to the components of the device, such as the relative positions of the top and bottom substrates inside the device. It can be understood that the device is multifunctional and is independent of its orientation in space.

[0045] For the convenience of description, in all embodiments of the present invention, it is stipulated that the upstream of the air flow corresponds to the front of the vacuum cleaner, and the downstream of the air flow corresponds to the rear of the vacuum cleaner.

[0046] Embodiment 1

[0047] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , the embodiments of the present invention provide a vacuum cleaner exhaust structure, which is mainly used for a handheld vacuum cleaner or a vacuum cleaner that needs to hold the vacuum cleaner main body. In existing vacuum cleaners, in order to facilitate the design of the internal motor and air flow path of the vacuum cleaner, the exhaust port is often set at the rear of the vacuum cleaner. However, as a handheld vacuum cleaner, in order to facilitate holding and operation, the handle is often also set at the rear of the vacuum cleaner. As a result, when using the vacuum cleaner, a large amount of air flow blows out backward from the exhaust port at the rear, often directly blowing on the user's arm or face, causing discomfort to the user and affecting the use experience.

[0048] In an embodiment of the present invention, the exhaust structure of the vacuum cleaner includes a main exhaust portion, a first auxiliary exhaust portion, and a second auxiliary exhaust portion. The main exhaust portion includes a main exhaust pipe 1 and a main exhaust hole 7 that are connected to each other. The main exhaust pipe 1 is disposed inside the housing of the vacuum cleaner main body, and the main exhaust hole 7 is disposed on the housing of the vacuum cleaner main body. The main exhaust portion retains part of the functions of the original exhaust portion, and the first auxiliary exhaust portion and the second auxiliary exhaust portion share part of the functions of the original exhaust portion.

[0049] If the original exhaust portion is completely abandoned, that is, the main exhaust portion is omitted, then in order to meet the requirement of the exhaust air flow rate, the first auxiliary exhaust portion and the second auxiliary exhaust portion need to increase the air flow rate, which instead increases the complexity of the circumferential structure inside the vacuum cleaner or increases the size of the vacuum cleaner. In an embodiment of the present invention, both the first auxiliary exhaust portion and the second auxiliary exhaust portion utilize the existing structures of the main exhaust portion and the housing of the vacuum cleaner main body, without increasing the structural complexity or the overall size of the vacuum cleaner main body. Specifically, the first auxiliary exhaust portion includes a first air outlet hole 3 and a first auxiliary exhaust hole 5 that are connected to each other. The second auxiliary exhaust portion includes a second air outlet hole 4 and a second auxiliary exhaust hole 6 that are connected to each other. The first air outlet hole 3 and the second air outlet hole 4 are both disposed on the main exhaust pipe 1. The first auxiliary exhaust hole 5 is disposed on the housing of the vacuum cleaner main body, and the second auxiliary exhaust hole 6 is disposed on the air collecting hood 8 of the vacuum cleaner main body. Since both the first auxiliary exhaust portion and the second auxiliary exhaust portion in the embodiment of the present invention are holes on the original structures of the main exhaust portion and the vacuum cleaner main body, the air flow path utilizes the space connected by the exhaust holes and the air outlet holes. Without adding additional components, ensuring that the structure remains unchanged and the size of the vacuum cleaner does not increase, the air flow rate of the main exhaust hole 7 is reduced to improve the comfort of the user.

[0050] In addition, the first auxiliary exhaust hole 5 is provided with a first conductive portion, and the second auxiliary exhaust hole is provided with a second conductive portion. The first conductive portion and the second conductive portion can blow the negative charges in the static electricity generated when the motor is running out of the vacuum cleaner with the air flow, preventing damage to the motor due to excessive static electricity. In an embodiment of the present invention, both the first conductive portion and the second conductive portion are in the form of conductor sheets, which can save materials, facilitate installation and fixation. Exemplarily, the conductor sheet is inserted into the side wall of the auxiliary exhaust hole. The conductor sheet is made of a single substance or alloy of a low-resistivity metal such as copper, and has a certain elasticity. Even if it is inserted and removed multiple times, it can still be used normally without being damaged by external forces.

[0051] In the embodiment of the present invention, the main exhaust duct 1 includes the main exhaust duct 1 and the air duct plate 2; the air duct plate 2 is connected to the outer shell of the vacuum cleaner main body, and divides the space between the outer shell of the vacuum cleaner main body and the air collecting hood 8 into an independent first space and a second space; the first space is communicated with the outside of the outer shell of the vacuum cleaner main body through the main exhaust hole 7; the second space is communicated with the outside of the outer shell of the vacuum cleaner main body through the second auxiliary exhaust hole 6; one end of the main exhaust duct 1 is communicated with the air outlet of the vacuum cleaner motor, and the other end is communicated with the first space. The air collecting hood 8 is arranged at the air outlet of the motor and is integrally connected with the motor housing. All the air flowing out of the motor air outlet is led out to the first space through the main exhaust duct 1, and then the air flows out through the main exhaust hole 7 immediately.

[0052] The first air outlet hole 3 is arranged on the main exhaust duct 1 and is used for communicating the space between the main exhaust duct 1 and the outer shell of the vacuum cleaner main body with the main exhaust duct 1. Part of the air flowing out of the motor air outlet will first flow into the space between the main exhaust duct 1 and the outer shell of the vacuum cleaner main body through the first air outlet hole 3, and then pass through the first auxiliary exhaust hole 5 and flow from the space between the main exhaust duct 1 and the outer shell of the vacuum cleaner main body to the outside of the outer shell of the vacuum cleaner main body, realizing the auxiliary exhaust of the first auxiliary exhaust part. The remaining air flow in the main exhaust duct 1 will flow into the first space. Since the first air outlet hole 3 is located upstream of the first space, the auxiliary exhaust effect of the first auxiliary exhaust part is extremely obvious. In the embodiment of the present invention, the first auxiliary exhaust part can reduce the air flow rate of the main exhaust part by 10%-30%.

[0053] The second air outlet hole 4 is arranged on the air duct plate 2 and is used for communicating the first space and the second space. The air flowing into the first space, in addition to being able to be discharged to the outside of the vacuum cleaner main body through the main exhaust hole 7, also has a part of the air flow entering the second space through the second air outlet hole 4, and the air flow entering the second space is discharged to the outside of the vacuum cleaner main body through the second auxiliary exhaust hole 6. The air collecting hood 8 is also integrally connected with the outer shell of the vacuum cleaner main body, that is, the motor housing, the outer shell of the vacuum cleaner main body, the air collecting hood 8 and the air duct plate 2 jointly form the second space. Since the air flow in the second space will flow through the outside of the motor housing, and in addition, the power supply component is arranged around the motor component, when the air flow flows in the second space, it can take away the heat generated by the operation of the motor and the power supply, playing a heat dissipation effect. After continuously operating the vacuum cleaner for 1 h, due to the heat dissipation effect of the second exhaust part, the temperature of the power supply will be 10%-20% lower than the temperature of the power supply of the vacuum cleaner without the second exhaust part. In the embodiment of the present invention, the second auxiliary exhaust part can reduce the air flow rate of the main exhaust part by 5%-10%.

[0054] Embodiment 2

[0055] Such as Figure 4 、 Figure 5 、 Figure 8 、 Figure 9As shown in the figure, an embodiment of the present invention provides a vacuum cleaner. The main body of the vacuum cleaner includes a detachable front part and a rear part. The cyclone dust collection structure of the vacuum cleaner is at least partially arranged in the front part. The motor assembly and the power supply assembly of the vacuum cleaner are both arranged in the rear part, and the power supply assembly surrounds the outside of the motor assembly. The rear part is also provided with an exhaust structure, which is the exhaust structure of the vacuum cleaner in Embodiment 1 of the present invention.

[0056] The air collecting hood 8 is arranged on the rear air inlet end face and jointly defines a second space with the outer shell of the vacuum cleaner main body, the outer shell of the motor assembly, the outer shell of the power supply assembly and the air duct plate 2, so that the airflow flowing through the second space can take away the heat generated by the operation of the motor and the power supply.

[0057] In the embodiment of the present invention, in addition to supplying power to the motor assembly, the power supply assembly also needs to supply power to the front part. Considering that the front part and the rear part can be detached, the second conductive part is the conductive sheet 10. The front part is provided with a conductive column, which can be inserted into the second auxiliary exhaust hole 6 and electrically connected to the conductive sheet 10. When the front part and the rear part are installed, the conductive column is connected to the conductive sheet 10 to realize the power supply of the power supply assembly to the front part. When the conductive column is inserted into the second auxiliary exhaust hole 6, there is a gap between the side wall of the conductive column and the side wall of the second auxiliary exhaust hole 6 to ensure that when the conductive column is inserted into the second auxiliary exhaust hole 6, the airflow can flow out from the second auxiliary exhaust hole 6.

[0058] When the detachable front part and rear part are installed together, the airflow enters the space between the front part and the rear part through the second auxiliary exhaust hole 6. There is a gap between the outer shell of the front part and the outer shell of the rear part. The airflow entering the space between the front part and the rear part is discharged outside the vacuum cleaner main body through this gap.

[0059] In order to be able to place the vacuum cleaner on a certain stable plane, the outer shell of the vacuum cleaner main body is provided with a support seat 11. The support seat 11 is provided with a support surface, and the projection of the center of gravity of the vacuum cleaner main body on the plane where the support surface is located falls within the support surface. The support seat 11 is at least partially arranged on the outer shell of the rear part.

[0060] Since the vacuum cleaner in the embodiment of the present invention is a handheld vacuum cleaner, it usually replenishes electric energy by charging. In the embodiment of the present invention, the support seat 11 is connected to the vacuum cleaner charger to realize the charging of the vacuum cleaner. Specifically, the first auxiliary exhaust hole 5 is arranged on the part of the support seat 11 located at the rear part; the first conductive part is the charging contact piece 9; the support seat 11 can be connected to the vacuum cleaner charger, and the charging contact piece 9 can be electrically connected to the vacuum cleaner charger. Since the vacuum cleaner does not work during charging, the connection of the charger will not affect the exhaust of the first auxiliary exhaust part. In order to prevent the user from misoperation, in the embodiment of the present invention, when the charger is connected to the support seat 11, the connection part of the charger is inserted into the first auxiliary exhaust hole 5, and there is a gap between the side wall of the connection part of the charger and the side wall of the first auxiliary exhaust hole 5, and the airflow can flow out from this gap.

[0061] In the embodiments of the present invention, since the first auxiliary exhaust hole 5 and the second auxiliary exhaust hole 6 have other functions in addition to exhausting air, the apertures of the first auxiliary exhaust hole 5 and the second auxiliary exhaust hole 6 need to comprehensively consider the requirements of the conductive part. Therefore, when the first auxiliary exhaust part and the second auxiliary exhaust part are provided simultaneously, the two can reduce the air flow rate of the main exhaust part by about 30%-40%.

[0062] Use the embodiments of the present invention to conduct user experience tests:

[0063] Randomly invite 50 men and 50 women aged 15-55 who are healthy as the test subjects for the user experience test.

[0064] The 100 test subjects first use the existing vacuum cleaner for 10 minutes, and then evaluate the experience of using the existing vacuum cleaner. More than 50% of the people think that the air flow at the exhaust port during the use of the existing vacuum cleaner will cause discomfort, and the other less than 50% of the people think it doesn't matter or can tolerate it.

[0065] The 100 test subjects then use the vacuum cleaner of the embodiments of the present invention for 10 minutes and evaluate the experience of using the vacuum cleaner of the embodiments of the present invention. More than 90% of the test subjects think that the air flow discharged from the main exhaust part does not cause discomfort to them.

[0066] At the same time, the test subjects are also required to compare the experience of using the existing vacuum cleaner with the experience of using the vacuum cleaner of the embodiments of the present invention. More than 70% of the test subjects think that the experience of using the vacuum cleaner of the embodiments of the present invention is better than that of the existing vacuum cleaner, and the other less than 30% of the test subjects think it doesn't matter or don't pay attention to the experience, only paying attention to the use effect.

[0067] In summary, the embodiments of the present invention provide a vacuum cleaner exhaust structure and a vacuum cleaner. Through the first auxiliary exhaust part and the second auxiliary exhaust part, the present invention can discharge some of the air flow discharged from the electrode out of the vacuum cleaner from the side of the vacuum cleaner, reducing the air flow rate discharged from the exhaust hole at the tail of the vacuum cleaner and improving the comfort of the user; when the second auxiliary exhaust part discharges air flow, the air flow flows through the space between the motor housing and the power supply housing and the rear housing, and the air flow passes through the power supply assembly surrounding the outside of the motor, which can reduce the temperature on the surface of the power supply assembly; both the first auxiliary exhaust hole 5 and the second auxiliary exhaust hole 6 of the present invention are provided with conductive parts, which can blow out the negative charges in the static electricity generated when the motor is running together with the air flow to the outside of the vacuum cleaner, preventing damage to the motor caused by excessive static electricity.

[0068] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
