Description

Technical Field

[0001] The present invention relates to the technical field of vacuum cleaners, and in particular to a water suction nozzle structure and a vacuum cleaner. Background Art

[0002] A vacuum cleaner is a household appliance that is mainly used to clean dust, debris and fine particles from the surface of objects. It can usually be equipped with a suction nozzle specifically for sucking up liquids (such as water, spilled beverages, etc.) to help users quickly clean liquid stains.

[0003] For example, Chinese patent CN202981883U discloses a vacuum cleaner and a wiper thereof, which include a connecting pipe, a wiper body and a rotating ring. The connecting pipe has a second pipe portion, and the rotating ring is clamped on the outside of the first pipe portion of the wiper body. The first pipe portion is relatively provided with two notches, and the first pipe portion is relatively provided with two grooves. The second pipe portion is relatively provided with two protrusions. The second pipe portion extends into the first pipe portion, and the two protrusions of the second pipe portion are clamped in the two notches of the first pipe portion. The two protrusions of the second pipe portion are clamped in the two grooves of the first pipe portion after rotating relative to the first pipe portion by a predetermined angle.

[0004] A wiper blade is installed in the above-mentioned wiper body. The wiper blade protrudes from the opening at the front end of the wiper body. It is usually made of a material with a certain degree of flexibility, such as a water-absorbing rubber made of rubber material or a plastic part made of soft plastic material. It absorbs and scrapes off surface moisture, maintains stable performance and shape under long-term use, and achieves a clean cleaning effect.

[0005] The existing installation structure between the wiper blade and the wiper body is mainly fixed by bolt connection, ultrasonic welding or glue bonding. The current connection method requires cumbersome assembly. The assembly method is limited by the lengthy process and high operating skills required, resulting in poor assembly flexibility and inconvenience in use, which needs to be improved. Summary of the Invention

[0006] In order to improve the problem that the wiper blade is inconvenient to use due to the complicated installation method, the present technical solution provides a water suction nozzle structure and a vacuum cleaner.

[0007] The purpose of this technical solution is achieved in this way:

[0008] A water suction nozzle structure comprises a shell, wherein a water suction flow channel is provided inside the shell for connecting to a vacuum cleaner;

[0009] The water suction channel is further provided with a mounting cavity, one end of which is connected to the front end of the housing and the other end is connected to the water outlet end of the water suction channel; and a wiper blade is further provided on the housing and fixed in the mounting cavity by a fixing structure;

[0010] The fixing structure includes a slot portion and an elastic locking portion. The elastic locking portion is protruding from the inner wall of the mounting cavity. The slot portion is correspondingly opened on the wiper blade. The slot portion and the elastic locking portion are engaged with each other so that the wiper blade is embedded in the mounting cavity and fixed.

[0011] Through the above technical solution, when the water suction nozzle is in normal use, the wiper blade needs to be installed at the front of the shell so that the end of the wiper blade is exposed for sucking liquid to clean stains. Under the suction force of the vacuum cleaner, the liquid is absorbed and transferred along the water suction channel inside the shell to the water outlet end, and finally stored in the liquid storage chamber inside the vacuum cleaner to achieve effective cleaning.

[0012] The wiper blade is installed on the housing by aligning the sheet-shaped wiper blade with the position of the installation cavity and embedding it. Based on the elastic deformation ability of the elastic embedding part, the wiper blade is continuously inserted until the groove part of the wiper blade touches the elastic embedding part of the inner wall of the installation cavity. The elastic embedding part deforms so that it is precisely embedded in the groove part, thereby fixing the wiper blade in the installation cavity. The fixing structure satisfies the simple plug-in operation, and the wiper blade can be quickly installed and firmly fixed without complicated steps and operations, thereby improving the convenience of use.

[0013] Preferably, there are two elastic locking portions, which are distributed in a one-to-one correspondence on opposite side walls of the installation cavity along the wiper blade embedding direction;

[0014] A clearance cavity for the wiper blade to pass through is formed between the two elastic embedding parts.

[0015] Through the above technical solution, by providing two elastic locking parts arranged opposite to each other, the clearance cavity formed is adapted to the wiper blade, and the wiper blade is allowed to pass through from one side of the opening. When the wiper blade is embedded in the installation cavity, the elastic locking parts on both sides can naturally embed into the two sides of the card groove, further enhancing the fixing strength and anti-slip performance of the fixing structure, making it less likely to loosen or fall off, and improving stability.

[0016] Preferably, a limiting portion is provided in the housing, and the limiting portion includes two limiting protrusions, which are located in a one-to-one correspondence on the inner walls of the mounting cavity on two opposite sides along the wiper blade embedding direction;

[0017] A positioning channel is formed between the limiting protrusions on both sides. The channel width of the positioning channel is adapted to the thickness of the wiper blade, and the wiper blade is located in the positioning channel.

[0018] Through the above technical solution, the limiting part is composed of two symmetrically distributed limiting protrusions, which are respectively located on the inner walls on both sides of the installation cavity along the embedding direction of the wiper blade. The two limiting protrusions enhance the structural stability of the shell and cooperate to form a positioning channel. The width of the channel is adapted to the thickness of the wiper blade, so that when the wiper blade is embedded in the installation cavity, the positioning channel guides the embedding direction of the wiper blade and the limiting protrusions on both sides play an upper and lower clamping and positioning effect, thereby improving the accuracy and stability of the installation of the wiper blade.

[0019] Preferably, there are a plurality of the limiting portions, one of which has the elastic locking portion, and the position of the elastic locking portion is arranged in a one-to-one correspondence with the limiting protrusion.

[0020] Through the above technical solution, the number of limiting parts is increased, and the multiple limiting parts cooperate to limit the swing and deviation of the wiper blade after installation, thereby enhancing the internal structural strength to improve the installation strength of the wiper blade, and further improving the accuracy and stability of the wiper blade installation.

[0021] Preferably, the elastic locking portion has a first guide surface, and the inclined directions of the first guide surfaces on both sides are relatively matched, so that the channel between the two elastic locking portions is expanded toward the embedding direction of the wiper blade.

[0022] Through the above technical solution, the wiper blade slides freely along the through end of the positioning channel, and the first guide surfaces on both sides are inclined in opposite directions and flared outward, so that the wiper blade can be embedded through the flared portion. The flared portion provides a guiding path that gradually reduces the resistance, which helps the wiper blade to more smoothly and accurately fit the card slot part and the elastic card embedding part during the installation process, further making the installation more convenient.

[0023] Preferably, the limiting protrusion has a second guide surface, and the inclination directions of the second guide surfaces on both sides are relatively matched, so that the inlet end of the positioning channel is expanded outward.

[0024] Through the above technical solution, the second guide surfaces on both sides are inclined in opposite directions, and the entrance end of the corresponding positioning channel is flared outward, which enhances the compatibility and adaptability of the positioning channel. It can be suitable for wiper blades with slight thickness errors, so that the wiper blade can be more smoothly embedded in the positioning channel during the installation process, making the installation more convenient.

[0025] Preferably, the wiper blade has a plug-in portion, the plug-in portion is located on a side of the wiper blade close to the housing, and the plug-in portion is provided with the slot portion;

[0026] The plug-in portion has a first inclined surface, which is located in a one-to-one correspondence on two opposite sides of the plug-in portion along the embedding direction of the wiper blade. The inclined direction of the first inclined surface makes the width of the plug-in portion gradually narrow toward the embedding direction.

[0027] Through the above technical solution, the plug-in portion extends toward the side close to the shell, and the inclination direction of the first inclined surfaces on both sides makes the width of the plug-in portion gradually narrower, making its shape more adapted to the shape of the mounting cavity, so that the wiper blade can be more smoothly and accurately inserted into the opening of the mounting cavity, and based on its protruding setting, the fixed position of the fixed structure is closer to the inside of the mounting cavity, thereby improving the connection strength to more effectively resist the risk of falling off or displacement, and further improving the stability and durability of use.

[0028] Preferably, the wiper blade has a second inclined surface, which is located one-to-one on two opposite sides of the wiper blade along the embedding direction, and the end surface of the mounting cavity close to the second inclined surface is in contact with the second inclined surface.

[0029] Through the above technical solution, the second inclined surface can be fitted with the inner wall of the installation cavity to further increase the stability of the wiper blade in the installation cavity, reduce the relative movement and large-scale swing of the wiper blade during use, and improve the adaptability of the wiper blade.

[0030] A vacuum cleaner comprises a vacuum cleaner body and at least one water suction nozzle as described above.

[0031] Through the above technical solution, when the vacuum cleaner is in normal use, the water suction nozzle is installed at the front end of the vacuum cleaner body through the shell. The vacuum cleaner body is equipped with a dust suction pipe. The water outlet end of the water suction flow channel is connected to the dust suction pipe port of the vacuum cleaner body, so that the water suction flow channel and the dust suction pipe are connected. When the vacuum cleaner is running, the suction force sucks the liquid obtained by the water suction nozzle along the connected channel into the chamber for liquid storage, thereby completing cleaning.

[0032] Compared with the existing technology, this technical solution has the following outstanding and beneficial technical effects:

[0033] 1. This technical solution aligns the wiper blade with the mounting cavity and inserts it. The elastic locking portion on the inner wall of the mounting cavity deforms and then inserts into the locking groove of the wiper blade. The wiper blade is fixed in the mounting cavity by a fixing mechanism. A simple plug-in operation can achieve quick installation and firm fixation, improving ease of use.

[0034] 2. This technical solution provides a limiting part in the shell. There are several limiting parts. Each limiting part includes two limiting protrusions. A positioning channel is formed between the two limiting protrusions. The limiting part strengthens the internal structure. The wiper blade is placed in the positioning channel. The limiting protrusions correspond one by one to the end faces of both sides of the wiper blade, which plays a role in limiting its up and down swinging, thereby improving the stability of the wiper blade installation.

[0043] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0044] Example:

[0045] See also Figure 1 and Figure 2 A water suction nozzle structure includes a housing 1 and a wiper blade 4. The wiper blade 4 is arranged at the front end of the housing 1. The wiper blade 4 is in a sheet-like structure. The wiper blade 4 is inserted into the housing 1 along one side of the width direction, and a portion of the other side is left exposed outside the front end of the housing 1 after insertion for cleaning. Figure 6 As shown, the specific insertion position of the wiper blade 4 is provided with a water suction channel 2 inside the shell 1, which runs through the shell 1 along the length direction, and a mounting cavity 3 is provided in the water suction channel 2, which is arranged on the front side of the shell 1. One end of the mounting cavity 3 is connected to the front end of the shell 1 and is formed with an opening, and the other end is connected to the water suction channel 2 to its water outlet end. The mounting cavity 3 shown in this embodiment is adapted to the wiper blade 4 in terms of spatial size and shape, and can just allow the wiper blade 4 to pass through the opening and enter the mounting cavity 3. The water outlet end of the water suction channel 2 is used for docking and conduction of the vacuum cleaner.

[0046] See also Figure 4A limiting portion 6 is provided in the shell 1, and there are multiple limiting portions 6. In this embodiment, there are three limiting portions 6, two of which are symmetrically arranged on both sides of the limiting portion 6 located in the middle position. Each limiting portion 6 includes two limiting protrusions 7, which are in the shape of long strips. Every two limiting protrusions 7 are fixed one-to-one to the inner walls on both sides of the mounting cavity 3 along the embedding direction of the wiper blade 4, and the length direction is arranged corresponding to the insertion direction.

[0047] A positioning channel 8 is formed between each two limiting protrusions 7 on opposite sides. The width of the positioning channel 8 is adapted to the thickness of the wiper blade 4. When the wiper blade 4 initially enters the installation cavity 3, its embedded end is just embedded in the positioning channel 8 and continues to move along the length direction of the positioning channel 8. Figure 7 As shown, the wiper blade 4 has two second inclined surfaces 13, which are located on the end surface on one side of the embedding direction of the wiper blade 4 and correspond one to one to the opposite sides of the embedding direction of the wiper blade 4. When the wiper blade 4 is fixed in the mounting cavity 3 by the fixing structure 5, the end surface in the mounting cavity 3 close to the second inclined surface 13 is in contact with the corresponding second inclined surface 13.

[0048] The fixing structure 5 includes an elastic locking portion 52 and has a certain elastic deformation capability. There are two elastic locking portions 52, and the two elastic locking portions 52 are protruded one by one on the opposite side walls of the installation cavity 3 along the embedding direction of the wiper blade 4. A clearance cavity 15 is formed between the two elastic locking portions 52 for the wiper blade 4 to pass through. Specifically, the limiting portion 6 arranged at the middle position has the elastic locking portion 52, and the elastic locking portions 52 on both sides are respectively arranged in one-to-one correspondence with the limiting protrusions 7 on both sides, and are located at the end of the corresponding limiting protrusion 7 away from the through end of the installation cavity 3, and both protrude toward the positioning channel 8.

[0049] See also Figure 3 The wiper blade 4 has a plug-in portion 11, which is located on the side of the wiper blade 4 close to the insertion direction, so that the plug-in portion 11 is protruded toward the position of the installation cavity 3, as shown in FIG. Figure 7 As shown, the plug-in portion 11 has two first inclined surfaces 12, and the first inclined surfaces 12 on both sides are located one-to-one on opposite sides of the width of the plug-in portion 11 along the embedding direction of the wiper blade 4. The inclination direction is coordinated so that the width of the plug-in portion 11 gradually narrows toward the embedding direction. The fixing structure 5 also includes a slot portion 51, which is opened on the plug-in portion 11 and vertically penetrates along the thickness of the plug-in portion 11. When the wiper blade 4 is embedded in the slot portion 51 and is engaged with the elastic embedding portion 52, the wiper blade 4 is fixed in the mounting cavity 3.

[0050] See also Figure 4 and Figure 5Each elastic locking portion 52 has a first guide surface 9, and the inclination directions of the first guide surfaces 9 of the elastic locking portions 52 on opposite sides are opposite. The first guide surfaces 9 on both sides are guided by the inclined surfaces so that the channel between the corresponding two elastic locking portions 52 is flared outward, and the flaring direction is set toward the embedding direction of the wiper blade 4.

[0051] Each limiting protrusion 7 has a second guide surface 10. The inclination directions of the second guide surfaces 10 of the limiting protrusions 7 on opposite sides are opposite. The second guide surfaces 10 on both sides are inclined to guide the corresponding positioning channels 8 to expand outward, and the expansion direction is also set toward the embedding direction of the wiper blade 4.

[0052] See also Figure 1 A vacuum cleaner includes a vacuum cleaner body 14, a water suction nozzle is installed on the vacuum cleaner body 14, and is fixedly connected to the vacuum cleaner body 14 through a shell 1. A threaded connection can be used to connect the water outlet end of the water suction channel 2 to the water inlet end of the vacuum cleaner body 14, thereby connecting the channels on both sides, making it convenient for the vacuum cleaner to start and obtain liquid from the wiper blade 4 through suction.

[0053] The specific working process of this program is as follows:

[0054] This technical solution is to install a wiper blade 4 at the front of the shell 1, with the end of the wiper blade 4 exposed to absorb liquid and clean stains. Under the suction of the vacuum cleaner, the liquid is absorbed and transferred along the water suction channel 2 inside the shell 1 to the water outlet end, and finally stored in the liquid storage chamber inside the vacuum cleaner. A fixing structure 5 is passed between the wiper blade 4 and the shell 1, and the sheet-like wiper blade 4 is aligned with the position of the installation cavity 3 and embedded. Based on the elastic deformation ability of the elastic embedding portion 52, the wiper blade 4 is continuously inserted until the slot portion 51 of the wiper blade 4 touches the elastic embedding portion 52 on the inner wall of the installation cavity 3. The embedding portion is deformed so that it is precisely embedded with the slot portion 51, so that the wiper blade 4 is fixed in the installation cavity 3. The fixing structure 5 satisfies the simple plug-in operation, and the wiper blade 4 can be quickly installed and firmly fixed without complicated steps and operations, thereby improving the convenience of use.
