The application provides a glass wiper, this glass wiper can restrict the flow that sewage flows out the sewage chamber when the body of wiping emptys, makes sewage be difficult for flowing out to external world, and then can avoid the emergence of the circumstances such as sewage pollution external environment, pollution user's clothing even, has promoted user's use and has experienced.

Fig. 1 is a schematic overall structure diagram of a glass wiper provided in an embodiment of the present application, fig. 2 is a structural diagram of a top view of the glass wiper shown in fig. 1, fig. 3 is a partial structural diagram of a cut-away view along an AA' view in fig. 2, and as shown in fig. 1 to 3, the glass wiper provided in an embodiment of the present application includes a wiper body 10, a scraping member 20 provided on a top of the wiper body 10, and a flow restriction member provided in the wiper body 10.

Specifically, as shown in fig. 3, wipe and have sewage chamber C in the body 10, wipe the top of body 10 and be equipped with collection dirty mouthful 11, the user is when using the glass that this application embodiment provided to wipe water the operation, and the sewage that is scraped off on the glass can be collected in flowing into sewage chamber C through collection dirty mouthful 11 to the windowsill, the ground of having avoided sewage to the glass area that has cleaned and glass below cause the pollution.

As shown in fig. 1-3, the scraping member 20 is disposed in the dirt collection opening 11, specifically, the scraping member 20 is a flat scraper, one end of which is located in the dirt collection opening 11, and the other end of which extends from the dirt collection opening 11 to the top end of the wiper 10. When a user performs a wiping operation, one side surface of the squeegee is opposed to the surface of the glass (this side surface is a wiping surface of the squeegee), and the top of the squeegee (for example, the long side of the top of the rectangular squeegee) is attached to the glass, and in the process of moving the wiper body 10 downward, the sewage flows downward into the sewage collection port 11 and then into the sewage chamber C.

Specifically, a water inlet channel is further arranged between the sewage collecting port 11 and the sewage cavity C in the wiper body 10, the water inlet channel allows sewage to flow into the sewage cavity C from the sewage collecting port 11, and a flow limiting piece which is used for guiding the sewage to the sewage cavity C and can limit the flow of the sewage flowing out of the sewage cavity C is arranged on the water inlet channel.

The application does not limit the specific structure and the number of the current limiting pieces. In the embodiment, the flow restrictor can guide the sewage entering from the sewage collecting port 11 into the sewage chamber C to complete the collection of the sewage when the wiper 10 is in the right position (the right position of the wiper 10 means the position state of the wiper 10 during normal wiping operation, namely the sewage collecting port 11 faces upwards); when the wiper 10 is tilted or inverted (i.e. the dirt collecting opening 11 faces obliquely downward or below, and the wiper 10 is in this position state due to misoperation when the user moves the glass wiper), the structure inside the wiper 10 is turned over (compared with the right position, the relative position relationship of the structure inside the wiper 10 in the vertical direction changes), and the sewage in the sewage chamber C has a tendency of flowing out of the sewage chamber C under the action of gravity. In other words, the current limiting piece only has the function of one-way current limiting, and does not influence water collection in normal water wiping operation.

For example, by providing the flow restriction on the water inlet passage, the area through which the sewage passes (hereinafter, referred to as a flow area) near the sewage collection port 11 can be made larger, and the flow area near the sewage chamber C can be made smaller, in the flow path of the sewage. Therefore, when the wiping body 10 is arranged rightly to collect sewage, the sewage firstly flows through a path with a large water passing area after entering the sewage collecting port 11 and flows towards the sewage cavity C under the action of self gravity, and a large amount of sewage can rapidly flow through the path with the large water passing area, so that the sewage cannot be accumulated at the sewage collecting port 11, the sewage collecting process cannot be influenced, and at the moment, the flow limiting piece plays a role in guiding the sewage to the sewage cavity C; when the wiper 10 is toppled or inverted, the sewage flows out of the sewage chamber C through a path with a small water area, and the flow rate of the sewage is small.

According to the glass wiper provided by the embodiment of the application, sewage enters the sewage collecting port 11 in the wiper body 10 and is arranged between the sewage cavities C which are arranged in the wiper body 10 and used for storing the sewage, which are arranged at the top of the wiper body 10 of the glass wiper, and a water inlet channel is arranged on the water inlet channel and is used for guiding the sewage to the sewage cavities C and limiting the flow of the sewage flowing out of the sewage cavities C. By arranging the flow limiting piece on the water inlet channel, when normal water scraping operation is carried out (the sewage collecting port 11 faces upwards), sewage scraped by the scraping piece 20 can enter the sewage cavity C under the drainage effect of the flow limiting piece after entering the sewage collecting port 11, and the collection of the sewage is finished; when the wiper 10 is in a tilted or inverted state (the soil collection opening 11 is directed obliquely downward or downward) due to a user's wrong operation, the flow restriction member restricts the flow rate of the soil flowing out of the soil chamber C. In the process of moving the glass wiper, after the wiper 10 is toppled or inverted by misoperation, a user can usually and rapidly adjust the position of the wiper 10 to enable the wiper to be in the upright state again, so that the time for the wiper 10 to be in the toppled or inverted state is short, at the moment, under the flow limiting effect of the flow limiting piece, sewage hardly flows out of the sewage cavity C, or a small amount of sewage flows out of the sewage cavity C, but the sewage hardly flows through the water inlet channel to flow out of the wiper 10 in a short time, and when the wiper 10 is restored to the upright state, the sewage enters the sewage cavity C again under the action of gravity to be collected. This application neither influences normal collection sewage operation through set up the current-limiting piece that has one-way current-limiting effect on inhalant canal, can also restrict the flow that sewage flows out sewage chamber C when wiping body 10 and being emptyd by the mistake simultaneously, makes sewage be difficult for flowing out to the external world, and then can avoid the emergence of the circumstances such as sewage pollution external environment, pollution user's clothing even, has promoted user's use and has experienced.

Optionally, the flow restriction member has a flow restriction channel communicating the dirt collection port 11 and the sewage chamber C, sewage enters the wipe body 10 from the dirt collection port 11 and then flows through the flow restriction channel into the sewage chamber C, and the cross-sectional area of the flow restriction channel gradually decreases in the direction in which sewage enters the sewage chamber C, that is, the aperture of the flow restriction channel at the end close to the sewage chamber C is smaller than the aperture of the section close to the dirt collection port 11. Therefore, when sewage is collected, the flow-limiting channel with a larger caliber communicated with the sewage collecting opening 11 can be used for a large amount of sewage to flow through and can guide the sewage to flow downwards into the sewage cavity C; when the wiper body 10 is toppled or inverted, the flow-limiting channel with a smaller diameter communicated with the sewage chamber C limits the flow of the sewage flowing out of the sewage chamber C. Through setting up the restriction flow path that the cross-sectional area reduces gradually, played the effect of one-way current-limiting, make sewage difficult for flowing to the external world when being in toppling over or the state of inversion in wiping body 10 short time.

Optionally, a plurality of flow-limiting pieces may be arranged at intervals on the water inlet channel to form different water passing areas on the flow path of the sewage, so as to perform the function of one-way flow limitation.

As shown in fig. 2 and 3, the flow restrictor includes a first clamping member 14 and a second clamping member 15, and the scraper member 20 is clamped between the first clamping member 14 and the second clamping member 15. As shown in fig. 3, the first clamping member 14 and the second clamping member 15 are respectively disposed on two opposite side walls of the wiping body 10 and extend in opposite directions, a gap for accommodating the wiping member 20 is provided between a front end surface (a surface abutting against a surface of the wiping member 20) of the first clamping member 14 and a front end surface of the second clamping member 15, and a width of the gap (a distance from the front end surface of the first clamping member 14 to the front end surface of the second clamping member 15) may be slightly smaller than a thickness of the wiping member 20 in order to ensure a good clamping effect.

Optionally, the first clamping member 14 and the second clamping member 15 are both plate-like structures.

In a possible embodiment, as shown in fig. 2 and 3, the first clamping member 14 comprises a transverse plate arranged perpendicular to the extension of the water inlet channel. When the cross section of the wiper 10 is rectangular, the cross plate extends along the length of the wiper 10, as shown in fig. 2.

In the present embodiment, the front end surface of the first clamping member 14 abuts against the wiping surface of the wiper member 20, that is, when wiping is performed, the first clamping member 14 is located between the wiper member 20 and the glass, and the sewage wiped by the wiper member 20 flows into the sewage chamber C through the first clamping member 14.

Alternatively, as shown in fig. 2, the plurality of transverse plates are arranged at intervals in the extending direction of the transverse plates, and a first water inlet 13 is formed in a gap between two adjacent transverse plates, so that the sewage entering from the sewage collecting port 11 flows to the sewage chamber C below. Specifically, the gap between adjacent transverse plates can be wider, so that a larger amount of sewage can flow through. Through setting up the diaphragm and utilizing the clearance that forms between the adjacent diaphragm to form first water inlet 13 on the inner wall of wiping body 10 at the interval, avoided trompil and then formed first water inlet 13's operation on the diaphragm, simple structure and processing technology are also comparatively simple.

Optionally, the horizontal plate is provided with a first water inlet 13. Illustratively, the first water inlet 13 is formed by a notch formed by the inward recess of the front edge of the transverse plate, or is a through hole formed in the transverse plate, and the through hole or the notch can be in any shape, such as rectangle, circle, special shape, etc. Thus, the degree of freedom in the arrangement position and the structural shape of the first water inlet 13 is higher.

Fig. 4 is a structural diagram of a top view of a wiper body of a glass wiper provided by another embodiment of the present application, fig. 5 is a cut-away view of the wiper body shown in fig. 4 from the same view as fig. 3, as shown in fig. 4 and 5, a first clamping piece 14 includes risers arranged along an extending direction of a water inlet channel, and the risers are arranged at intervals, and a gap between two adjacent risers forms a first water inlet 13.

As shown in fig. 5, at this time, the first clamping member 14 extends in the direction in which the sewage enters the sewage chamber C to form a vertical plate, and the vertical plate is provided in plurality at intervals in the longitudinal direction of the wiper body 10.

As shown in fig. 4, the gap between two adjacent vertical plates forms the first water inlet 13, and the gap is wide, so that a large amount of sewage can rapidly flow through the gap, and the sewage is prevented from accumulating at the sewage collecting port 11.

Through setting up a plurality of first water inlets 13 on the length direction of wiping body 10 to first water inlet 13 crosses the water area great, makes can flow through a large amount, fast from the sewage that dirty mouthful 11 inflows of collection, plays the effect with sewage drainage to sewage chamber C, in order to avoid collecting untimely to sewage when wiping the water operation, causes the condition of sewage pollution ground or windowsill.

Further, as shown in fig. 2, the second clamping member 15 is a transverse plate extending along the length direction of the wiper body 10 and penetrating through the length direction of the wiper body 10, and the second clamping member 15 abuts against the surface of the wiper member 20 in the length direction of the wiper member 20, and is matched with the first clamping member 14 to provide a good fixing effect for the wiper member 20.

In the embodiment of the present application, the second clamping member 15 is not provided with a water inlet through which the sewage flows. When normal wiping operation is performed, the sewage scraped from the glass enters the sewage collecting port 11 (i.e., the position where the first clamping member 14 is disposed) from the side of the wiping surface of the scraping member 20, so that the collection of the sewage is not affected by the absence of the water inlet in the second clamping member 15, and when the wiping body 10 is tilted, the sewage can be completely prevented from flowing out from the second clamping member 15.

Alternatively, the scraping member 20 may be fixedly clamped between the first clamping member 14 and the inner wall of the wiping body 10 opposite to the first clamping member 14.

In the embodiment of the present application, as shown in fig. 2, 3 and 5, the restrictor further includes a restrictor plate 12, the restrictor plate 12 is located below the first clamping member 14, the restrictor plate 12 and the wall surface of the wiper 10 define a sewage chamber C, and the restrictor plate 12 is provided with a second water inlet 120 communicated with the sewage chamber C.

Specifically, the size of the current limiting plate 12 matches with the size of the inside of the wiper body 10 to define a closed sewage chamber C together with the inner wall of the wiper body 10, and the current limiting plate 12 is provided with a second water inlet 120 for sewage to enter the sewage chamber C. The sewage entering the wiper 10 from the sewage collection port 11 flows through the first water inlet 13, then flows to the current-limiting plate 12 and enters the sewage chamber C through the second water inlet 120.

It should be understood that the second water inlet 120 is arranged such that the sewage is not easily discharged from the sewage chamber C.

Optionally, the second water inlet 120 includes a plurality of through holes 121 spaced apart from each other on the restrictor plate 12.

Specifically, the diameter of each through-hole 121 is small, and for example, when the through-hole 121 is a circular through-hole, the diameter of the through-hole 121 may be 1mm to 5 mm. Thus, the water passing area of each through hole 121 is small, the water flow is also small, and when the wiper 10 is inclined or inverted, the restrictor plate 12 has a good effect of restricting the outflow of sewage in the sewage chamber C.

Further, perforating hole 121 can stagger the setting with first water inlet 13, so, even if there is a small amount of sewage through perforating hole 121 outflow sewage chamber C, platelike structure's first holder 14 and second holder 15 also can play the effect that blocks to sewage for sewage is difficult more flows to the external world from wiping body 10 in, when wiping body 10 and getting back to the position of putting just, sewage can get into in the sewage chamber C from perforating hole 121 once more under the effect of gravity.

This application sets up first holder 14 and current-limiting plate 12 through the interval on inhalant canal to set up the first water inlet 13 that can the drainage sewage and can restrict the second water inlet 120 of sewage outflow, realized the one-way current-limiting to sewage, simple structure, processing are convenient, and then can reduce the manufacturing cost of this product, improve market competition.

Moreover, when the moving speed of the wiper 10 is fast and the sewage in the sewage cavity C has a large shaking range, the first clamping member 14 and the current limiting plate 12 which are arranged at an interval also play a role in preventing splashing of sewage, thereby improving the use experience of the user.

Fig. 6 is a cross-sectional view of a wiper according to another embodiment of the present invention, and as shown in fig. 6, the through hole 121 may have a bell mouth shape with a large top and a small bottom, i.e., one end with a large diameter faces the first holder 14 and the other end with a small diameter faces the sewage chamber C. When the wiper 10 is rightly placed, the larger aperture of the through hole 121 has better guiding and drainage effects on the sewage to flow into the sewage cavity C, and when the wiper 10 is reversely placed, the smaller aperture of the through hole 121 has better flow limiting effects on the sewage.

For example, the through holes 121 may be spaced apart along the length of the restrictor plate 12.

Fig. 7 is a cross-sectional view of a wiper according to another embodiment of the present application, which is viewed from the same perspective as fig. 3. as shown in fig. 7, the restrictor plate 12 includes a first plate portion 12a and a second plate portion 12b disposed on two opposite inner walls of the wiper 10, and a second water inlet 120 is formed by a gap between the first plate portion 12a and the second plate portion 12 b.

Specifically, the first plate portion 12a and the second plate portion 12b extend in the longitudinal direction of the wiper 10 with a gap between the front end faces thereof, so that the second water inlet 120 also has a strip-shaped hole 122 extending in the longitudinal direction of the wiper 10. It will be appreciated that the gap between the first and second plate portions 12a, 12b is narrow to enable a better restriction of the flow of sewage out of the sewage chamber C.

Forming the second water inlet 120 in this manner eliminates the need to open a hole in the restrictor plate 12, which can improve production efficiency.

Further, the cross-sectional area of the second water inlet 120 is gradually reduced in a direction in which the sewage enters the sewage chamber C. For example, the through-hole 121 has a trumpet shape. For another example, in the direction in which the sewage enters the sewage chamber C, that is, in the thickness direction of the first plate portion 12a and the second plate portion 12b, the front end surface of the first plate portion 12a and the front end surface of the second plate portion 12b gradually approach each other (which may be achieved by providing an inclined surface), so that the longitudinal section of the formed strip-shaped hole 122 is in a "V" shape, or in a "Y" shape as shown in fig. 7.

Through such an arrangement, the second water inlet 120 plays both a role of limiting the outflow of sewage when the wiper body 10 is inverted and a role of guiding sewage into the sewage chamber C, thereby facilitating the sewage to rapidly enter the sewage chamber C when collecting the sewage.

Fig. 8 is an exploded view of the wiper of the glass wiper shown in fig. 2, and as shown in fig. 8, the wiper 10 includes a first half shell 101 and a second half shell 102 butted against each other to clamp the wiper 20, and a first clamping member 14 and a second clamping member 15 are respectively fixedly provided on inner walls of the first half shell 101 and the second half shell 102.

Illustratively, the first clamping member 14 is disposed on an inner wall of the first half-shell 101 and is integrally formed with the first half-shell 101 through an integral molding process, and the first half-shell 101 and the second half-shell 102 are butted to each other, so that the scraper 20 is mounted and clamped, and the assembly is simple.

As shown in fig. 8, the scraping element 20 is provided with a positioning slot 23, and a protrusion 17 matched with the positioning slot 23 is provided on at least one of the first clamping element 14, the second clamping element 15 and the inner wall of the scraping body 10.
