In a first aspect, an embodiment of the present utility model provides a window wiper with a simple valve structure, which can reduce a production cost of the window wiper and facilitate a user to use the window wiper by optimizing and improving the valve structure, thereby being beneficial to large-scale popularization and application of products. The window wiper may be a glass wiper as described above, which can be used to wipe and clean glass surfaces.

Fig. 1 is a schematic view of the overall structure of a window wiper according to an embodiment of the present utility model. Fig. 2 is a top view of a window wiper provided in an embodiment of the utility model. Fig. 3 is a schematic cross-sectional view of the AA view of fig. 2.

As shown in fig. 1 to 3, the window wiper provided by the embodiment of the utility model comprises a wiper body, wherein the wiper body is provided with a wiper wall 10 and a water supply cavity 20, a wiper 70 and a water outlet 51 are arranged on the outer surface (i.e. a wiper surface) of the wiper wall 10, a water flow channel is formed between the water supply cavity 20 and the water outlet 51, water in the water supply cavity 20 can flow into the water outlet 51 through the water flow channel, and water is supplied to the wiper 70 and the glass surface on the wiper surface through the water outlet 51, so that the cleaning effect of the wiper body on the glass surface to be cleaned is ensured.

Further, the window wiper provided by the embodiment of the utility model further comprises a valve core 30, wherein the valve core 30 is configured to: under the action of inertia force and/or gravity force, the wiper body is displaced so that a water flow channel between the water supply cavity 20 and the water outlet 51 is conducted.

Specifically, the valve core 30 in the window wiper provided by the embodiment of the utility model is movably arranged in the wiper body and is used for opening or closing the water flow channel. The valve core 30 is reasonably kept in the valve body, and can displace relative to the wiping body under the action of inertia force and/or gravity force applied by the valve core 30, so that the valve port is opened, a water flow channel between the water supply cavity 20 and the water outlet 51 is conducted, water in the water supply cavity 20 can flow into the water outlet 51, and water is supplied to the wiping object 70 on the wiping surface through the water outlet 51.

When the motion state of the wiper body changes (such as acceleration or deceleration), the valve core 30 will generate acceleration, the inertia of the valve core 30 will make itself have a tendency to keep the original motion state, at this time, the valve core 30 will receive the inertial force opposite to the acceleration direction, under the inertial force, the valve core 30 can displace relative to the wiper body, the valve port is opened, and then the water flow channel between the water supply cavity 20 and the water outlet 51 is conducted.

For example, when the window wiper is used, the window wiper needs to be moved back and forth closely to the glass surface, and the kinetic energy of the movement of the window wiper can be fully utilized to enable the valve core 30 to be subjected to the action of inertia force, so that the valve core 30 is displaced relative to the wiper body, and a water flow channel between the water supply cavity 20 and the water outlet 51 is conducted.

For another example, before the cleaning operation, the user may change the motion state of the wiper body by means of translation, shaking, swinging, switching the moving direction (also rotating), etc., at this time, the valve core 30 may be acted on by the inertial force, and the valve core 30 may be displaced relative to the wiper body, so that the water flow channel between the water supply cavity 20 and the water outlet 51 is conducted, and the water supply cavity 20 may supply water to the wiper 70 and the glass surface on the wiping surface.

Here, the inertial force means: when an object has acceleration, the inertia of the object can lead the object to have a tendency of keeping the original motion state, and when the object is taken as a reference system and a coordinate system is established on the reference system, the object appears to have a force with opposite directions acting on the object to enable the object to displace in the coordinate system, so the inertial force is called.

Inertial forces are generally divided into translational inertial forces and rotational inertial forces. For translational inertial force, the magnitude of the inertial force is related to the mass m of the inertial force and the acceleration a of the inertial force, and the inertial force F= -ma. Wherein a negative sign indicates that the direction of the inertial force is opposite to the direction of the acceleration. The larger the acceleration a, the larger the inertial force F itself receives, and when the acceleration is 0, the inertial force F itself receives is equal to 0. That is, when the spool 30 is in a stationary state or a uniform linear motion state, it will not receive the inertial force by itself, and the spool 30 cannot be moved by the inertial force.

In the rotating frame of reference, the object is also subjected to inertial forces, which are then divided into inertial centrifugal forces and coriolis forces. That is, the spool 30 may also be subjected to the rotational inertia force.

In summary, the user may move the wiper body through non-uniform translation, shaking, swaying, rotation or swing, so that the valve core 30 is subjected to the translational inertial force or the rotational inertial force, and the valve core 30 is further enabled to displace to open the valve port.

The valve core 30 can also displace relative to the wiper body under the action of gravity, so that the water flow channel between the water supply cavity 20 and the water outlet 51 is conducted. At this time, the user can disengage the valve core 30 from the valve port under the gravity action by rotating the wiper at an angle to open the valve port, so that the water flow channel between the water supply chamber 20 and the water outlet 51 is conducted.

Alternatively, in order to enable the spool 30 to be subjected to a sufficiently large inertial force and/or gravity force, the spool 30 should be of sufficient mass.

Alternatively, the valve core 30 may be made of metal, such as stainless steel or copper alloy, aluminum alloy, or the like.

Alternatively, the valve core 30 may be constructed of a relatively dense plastic.

Alternatively, the valve core 30 may be made of glass.

Since the spool 30 may be subjected to both the inertial force and the gravitational force, the displacement of the spool 30 may be caused by either one of the inertial force and the gravitational force, or both of them, which is not limited in the present utility model.

Optionally, the spool 30 is configured to: under the action of inertia force, the wiper body is displaced so that the water flow channel between the water supply cavity 20 and the water outlet 51 is conducted.

For example, the inertial force may be a translational inertial force and/or a rotational inertial force.

For another example, the rotational inertial force may be an inertial centrifugal force or a coriolis force.

Optionally, the spool 30 is configured to: under the action of gravity, the wiper body is displaced so that a water flow channel between the water supply cavity 20 and the water outlet 51 is conducted.

Optionally, the spool 30 is configured to: under the combined action of the inertia force and the gravity, the water supply cavity 20 and the water outlet 51 are communicated.

According to the window wiper provided by the embodiment of the utility model, the valve core 30 can move under the action of the inertia force and/or gravity force of the valve core, so that a water flow channel between the water supply cavity 20 and the water outlet 51 is conducted, and an additional transmission mechanism is not required to be arranged to drive the valve core 30 to move, thereby simplifying the structure of the valve, reducing the production cost and enabling the product to be more competitive.

According to the window wiper provided by the embodiment of the utility model, the valve core 30 can move under the action of the inertia force and/or gravity force, at the moment, a user can move the valve core 30 in a non-uniform translation, shaking, swaying, rotating or swaying mode and the like, so that a water flow channel between the water supply cavity 20 and the water outlet 51 is conducted, the water outlet mode is simple and easy to use, the use of the user can be facilitated, and the user acceptance is high, thereby being beneficial to the large-scale popularization and application of products.

When the window wiper is used, the window wiper needs to be clung to the surface of glass and is moved back and forth, the movement is generally irregular, the window wiper provided by the application embodiment can fully utilize the kinetic energy of the movement to move the valve core 30, at the moment, a user does not need to specially do additional actions to enable the water flow channel to be conducted, the 'no-perception' water outlet can be realized, the use of the user can be facilitated, and the cleaning efficiency is improved.

Further, in the embodiment of the present utility model, the spool 30 is further configured to: under the action of inertial force and/or gravity, the wiper body is displaced so that the water flow channel between the water supply cavity 20 and the water outlet 51 is closed.

Similarly, the valve core 30 may be displaced relative to the wiper body under the action of the inertial force and/or gravity, so as to close the valve port, and further close the water flow channel between the water supply cavity 20 and the water outlet 51. At this time, the user may close the valve port in a similar manner to the valve port opening (e.g., the valve core 30 moves by non-uniform translation, shaking, swaying, rotating or swinging), which is not described herein.

It should be noted that, the valve core 30 is moved to open or close the valve port, and may be implemented under different forces, which are not necessarily causal, and the present utility model is not limited thereto.

Alternatively, the valve element 30 may open the valve port under its own inertial force and/or gravity, and close the valve port under its own gravity.

For example, the wiper may be rotated in a direction such that the valve spool 30 is disengaged from the valve port by gravity to open the valve port. When the valve port needs to be closed, the wiper body can be rotated in the opposite direction, so that the valve core 30 is reset under the action of gravity to close the valve port.

Alternatively, the valve element 30 may open the valve port under its own inertial force and/or gravity, and close the valve port under its own inertial force.

For example, the wiper may be moved in a direction such that the valve spool 30 is disengaged from the valve port by inertial force to open the valve port. When the valve port needs to be closed, the wiper body can be moved in the opposite direction, so that the valve core 30 is reset under the action of inertial force in the opposite direction to close the valve port.

Alternatively, the valve element 30 may open the valve port under its own inertial force and/or gravity, and close the valve port under its own inertial force and/or gravity.

It should be noted that, because water exists in the water flow channel, the valve core 30 is also subjected to the action of water pressure, and the valve core 30 provided by the embodiment of the utility model can overcome the action of water pressure, so that the valve core 30 can open or close the valve port under the action of inertia force and/or gravity force applied by the valve core 30.

According to the utility model, the valve core 30 can move under the action of inertia force and/or gravity force, so that the water flow channel between the water supply cavity 20 and the water outlet 51 is closed, and an additional transmission mechanism is not required to drive the valve core 30 to close the valve port, thereby further simplifying the structure of the valve, reducing the production cost and enabling the product to have more competitive power.

Optionally, in other embodiments, the valve cartridge 30 is further configured to: under the action of the elasticity or magnetic force, the wiper body is displaced so that the water flow channel between the water supply cavity 20 and the water outlet 51 is closed.

That is, the valve body 30 may be provided in a normally closed form, and the valve body 30 may be moved to open the valve port by inertia and/or gravity, and the valve body 30 may be restored to close the valve port by elastic force or magnetic force, so that the water flow path between the water supply chamber 20 and the water outlet 51 is closed.

For example, a spring is arranged between the valve core 30 and the wiper body, and the valve core 30 can be reset by the elastic force (tensile force or pushing force) of the spring so as to close the valve port.

For another example, the valve core 30 is magnetically matched with the wiper body, and the valve core 30 can be reset by the magnetic force (attractive force or repulsive force) of the magnet so as to close the valve port.

Fig. 4 is a structural comparison diagram of the valve element 30 in different states. As shown in fig. 3 and 4, the water flow channel between the water supply cavity 20 and the water outlet 51 comprises a valve cavity 40, a first end of the valve cavity 40 is communicated with the water supply cavity 20, and a second end of the valve cavity 40 forms a necking (corresponding to a valve port); the valve spool 30 is movably disposed within the valve chamber 40 and is configured to:

the valve core 30 is away from and opens the constriction so that the water flow passage between the water supply chamber 20 and the water outlet 51 is conducted; the valve core 30 approaches and closes the constriction so that the water flow passage between the water supply chamber 20 and the water outlet 51 is closed.

As shown in parts (b), (c) and (d) of fig. 4, under the action of the inertial force and/or gravity applied to the valve core 30, the valve core can be far away from and open the necking (corresponding to the valve port) so that the water flow channel between the water supply cavity 20 and the water outlet 51 is conducted.

The cross-sectional area of the first end of the valve chamber 40 is larger than the cross-sectional area of the spool 30, and the spool 30 is movable in the valve chamber 40 in the radial direction or the axial direction. For example, the spool 30 moves to the left front, right front, or upward in fig. 4 with respect to the valve chamber 40. At this time, the water flow can flow out through the gap between the spool 30 and the wall of the valve chamber 40 at the constriction.

As shown in fig. 3 and fig. 4 (a), the valve core 30 has a (cross-sectional) shape matching the shape of the constriction, and the valve core 30 approaches and closes the constriction under the action of the inertial force and/or gravity applied to itself, so that the water flow passage between the water supply chamber 20 and the water outlet 51 is closed. The necking can play a limiting role on the valve core 30, and prevent the valve core 30 from being separated from the valve cavity 40 to the outside of the wiper body.

In the embodiment of the present utility model, the valve core 30 is a sphere (ball), the shrinkage port is a circular shrinkage port, and the sizes of the two are adapted, so when the valve core 30 seals the circular shrinkage port, the shrinkage port can be completely closed, and at the moment, water cannot flow out through the shrinkage port.

Fig. 5 is a schematic structural view of an example of the valve element 30 according to the embodiment of the present utility model. In other embodiments, as shown in fig. 5, the valve core 30 may be a cone, which may be a cone as a whole, or may be a cone with a front end and a rear end being a cylinder as shown in fig. 5. The cone is mutually matched with the circular necking, and the circular necking can be opened or closed under the action of inertia force and/or gravity force.

As shown in fig. 3 to 5, a water outlet pipe 50 is convexly arranged on the outer surface of the wiping wall 10, one end of the water outlet pipe 50 is communicated with the water supply cavity 20, the other end forms a water outlet 51, and the valve cavity 40 is formed in the water outlet pipe 50. Through the arrangement, the valve cavity 40 can be conveniently arranged, the processing difficulty and the production cost are reduced, and the production efficiency is improved.

Alternatively, the water outlet pipe 50 and the wiping wall 10 may be integrally formed by injection molding or the like, so that the production process can be simplified, the production efficiency can be improved, and the mechanical strength of the connection of the two can be improved.

As shown in fig. 3-5, the necking of the valve cavity 40 is the water outlet 51, and by the arrangement, the lengths of the water flow channel and the water outlet pipe 50 can be shortened, and the structure of the wiper body can be optimized.

Alternatively, the cross-sectional shapes of the water outlet pipe 50 and the valve cavity 40 may be the same or different, which is not limited in the present utility model. In the embodiment of the present utility model, the water outlet pipe 50 is a circular pipe, and the valve cavity 40 has a circular cross-sectional shape, and the valve cavity 40 includes a cylindrical section and a conical section (tapered section) connected to each other, and the end of the conical section forms the water outlet 51.

Alternatively, the water outlet pipe 50 may be a square pipe or a conical pipe.

As shown in fig. 3 to 5, the wiper 70 is provided on the outer surface of the wiper wall 10, the wiper 70 is provided with a positioning hole, and the water outlet pipe 50 is penetrated in the positioning hole.

With the above arrangement, on the one hand, water can be directly supplied to the wiper 70 through the water outlet 51. On the other hand, the water outlet pipe 50 is mutually matched with the positioning hole, and when assembling, an assembler can sleeve the wiper 70 on the water outlet pipe 50 through the positioning hole, and then the installation angle of the wiper 70 can be simply and finely adjusted, so that the assembling efficiency of the wiper 70 can be improved.

As shown in fig. 3-5, the water outlet 51 (i.e., the front end of the water outlet tube 50) is recessed from the outer surface of the wipe 70.

That is, there is a height difference between the outer surface of the wiper 70 and the front end portion of the water outlet pipe 50, the outer surface of the wiper 70 has a greater height (more far from the wiping surface) than the front end portion of the water outlet pipe 50, and the height of the water outlet pipe 50 is smaller than the thickness of the wiper 70, so that the water outlet pipe 50 can be prevented from contacting the glass surface by the above arrangement, thereby reducing the friction force between the wiper and the glass surface, and avoiding damage to the glass surface due to hard friction between the water outlet pipe 50 and the glass surface.

As shown in fig. 3 and fig. 4 (a), the front end of the valve body 30 can protrude from the water outlet 51. Through the arrangement, the valve core 30 can retract into the valve cavity 40 under the extrusion of the glass surface, so as to open the necking (namely the water outlet 51) of the valve cavity 40, and further communicate with the water flow channel.

As shown in fig. 3 to 5, a first end (an end near the water supply chamber 20) of the valve chamber 40 is provided with a stopper 60, and the stopper 60 is used to restrict the valve core 30 within the valve chamber 40. With the above arrangement, the valve body 30 can be held in the valve chamber 40 so as not to be moved into the water supply chamber 20, and thus the operation state of the valve body 30 can be controlled well.

The form of the limiting member 60 is not limited, and any limiting function as long as it can perform the aforementioned limiting function while ensuring that the first end of the valve chamber 40 is communicated with the water supply chamber 20 should be accommodated within the scope of the present utility model. As shown in fig. 3 and 4, in the embodiment of the present utility model, the limiting member 60 is a limiting sleeve, the inside of the limiting sleeve is provided with a hollow structure 61 through which water flows, and the front end of the limiting sleeve can penetrate into the valve cavity 40 to perform a better limiting function.

Alternatively, the stop collar may be secured to the first end of the valve cavity 40 by clamping, screwing, riveting or bonding.

For example, an external thread may be disposed on the outer surface of the front end portion of the stop collar, and an external thread that is matched with each other may be disposed on the inner surface of the valve cavity 40 (i.e., the inner surface of the water outlet pipe 50), so that the front end portion of the stop collar may be screwed into the valve cavity 40, and then the stop collar may be fixed to the first end of the valve cavity 40.

Fig. 6 is a schematic structural view of another example of a mounting structure of a stop collar according to an embodiment of the present utility model. As shown in fig. 6, the stop collar may be clamped into the valve cavity 40, at this time, a smooth transition protrusion structure may be disposed on the outer surface of the front end portion of the stop collar, and a mutually matched clamping groove may be disposed on the inner surface of the valve cavity 40, so that the front end portion of the stop collar may be clamped into the valve cavity 40, and further the stop collar is fixed at the first end of the valve cavity 40.

In other embodiments, the protruding structure may be provided on the inner surface of the valve chamber 40, and the engaging groove may be provided on the outer surface of the front end portion of the spacer.

As shown in fig. 5, the limiting member 60 may be a limiting protrusion protruding from the inner wall of the valve chamber 40. The spacing projections may include a plurality of projections and be distributed at the same height in the valve chamber 40 to provide a better spacing effect.

As shown in fig. 2 and 3, a plurality of supporting protrusions 11 may be uniformly disposed on the outer surface (i.e., wiping surface) of the wiping wall 10, and the tips of the supporting protrusions 11 do not protrude beyond the outer surface of the wiper 70.

Specifically, by providing the supporting protrusions 11, the contact area between the outer surface of the wiping wall 10 and the glass surface can be reduced, and the surface contact is converted into point contact, so that the friction force between the two is reduced, and the movement of the wiping body can be smoother. In addition, since the tip of the supporting projection 11 does not protrude beyond the outer surface of the wiper 70, it is ensured that the wiper 70 can sufficiently contact the glass surface, so that the cleaning effect of the wiper 70 can be improved.

Alternatively, the wipe 70 can be a flexible cleaning article. The material of the wiper 70 may be any of felt, cleaning cloth, scouring pad, sponge, rubber, etc.

As shown in fig. 1 to 3, in order to improve the cleaning efficiency, in the embodiment of the present utility model, a scraping member 80 is further disposed on the outer surface of the wiping wall 10, and the scraping member 80 can be used to scrape and clean the dirt such as water stains on the glass surface, so as to achieve "scraping before scraping" and improve the cleaning efficiency. For example, the scraping member 80 may be any one of a scraping bar, a scraper, a cleaning brush, and the like capable of performing a scraping operation.

In an embodiment of the present utility model, the scraper 80 may be a scraper bar.

Alternatively, the scraping strip can be made of plastic or rubber materials.

Alternatively, the wiper strip may have an arc shape with opposite ends protruding away from the center of the wiping wall 10, thereby allowing better water collection.

As shown in fig. 1 and 3, the wiper body is provided with a water filling port for supplying water to the water supply cavity 20, the water filling port is provided with a water cavity cover 21, and the water cavity cover 21 can seal the water filling port and is detachably connected with the wiper body. The water chamber cover 21 may be made of a flexible material, such as a soft gel.

The water cavity cover 21 is also provided with a one-way ventilation valve 22 for balancing the air pressure inside and outside the water supply cavity 20. The one-way ventilation valve 22 is configured such that air can be introduced into the water supply chamber 20 through the one-way ventilation valve 22 from the outside, and water in the water supply chamber 20 cannot be introduced into the outside through the one-way ventilation valve 22.

It should be noted that when the water flow channels are communicated, the external air can also enter the water supply cavity 20 through the water outlet 51 and the valve cavity 40 to balance the air pressure inside and outside the water supply cavity 20. The water outlet 51 may be provided slightly larger for a better balancing effect.

In a second aspect, embodiments of the present utility model also provide a window wiper assembly comprising a first window wiper and a second window wiper that are attracted to each other by magnetic force, at least one of the first window wiper and the second window wiper being a window wiper provided in any of the foregoing embodiments.

Optionally, magnets with different polarities are respectively arranged on the first window wiper and the second window wiper.

Optionally, one of the first window wiper and the second window wiper is provided with a magnet, and the other one is provided with a magnetic material such as an iron block, a steel block and the like.

For example, as shown in fig. 3, the first window wiper may be a window wiper provided in the foregoing embodiments, in which the magnet assembly 90 is disposed, and in which the magnetic steel may be disposed.

Alternatively, the first and second wipers may also be attracted to each other by an electromagnet.

At this time, since the first and second window wipers can be attracted to each other by magnetic force, the first and second window wipers can be adsorbed to both surfaces of the glass, respectively. The user can drive the window wiper that is located the window inboard through handle or push-and-pull rod and remove, and under the effect of magnetic attraction, the window wiper of outside also moves together, and then can clean glass's inside and outside surface simultaneously.

The scraping assembly adopts the window wiper provided by the previous embodiment, so that the scraping assembly also has the corresponding technical effects as the window wiper, and the detailed description is omitted.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
