Since the main inventive point of the present invention is to improve the rinsing head 100, in the following embodiments, the rinsing head 100 will be explained mainly with reference to the accompanying drawings.

Referring to fig. 1 to 3, in an embodiment, the rinsing head 100 includes the connecting tube 110, the rod 120, the mounting plate 130, the pushing plate 140 and the cleaning assembly 150, wherein the connecting tube 110 has the water outlet end 111 for spraying the water toward the front under high pressure; the rod body 120 protrudes forwards from the water outlet end 111; the mounting plate 130 and the push plate 140 are sequentially arranged on the rod body 120 at intervals from front to back, and the push plate 140 can be movably arranged along the front-back direction; the cleaning assembly 150 includes a cleaning block 151 movably disposed in a direction approaching to and away from the rod 120, and two connecting rods 152, wherein one end of each of the two connecting rods 152 is hinged to the inner side and the outer side of the cleaning block 151, and the other end of each of the two connecting rods 152 is hinged to the mounting plate 130 and the push plate 140, so that when the push plate 140 is driven by the water ejected from the water outlet end 111 at a high pressure to move forward, the two connecting rods 152 drive the cleaning block 151 to move away from the rod 120 to abut against the inner wall of the cooling water pipe 500.

In the technical scheme provided by the utility model, when a water body is sprayed forwards at high pressure from the water outlet end 111 of the connecting pipe 110, the water body is sprayed on the push plate 140 and applies forward thrust to the push plate 140 to drive the push plate 140 to move forwards, so that the two connecting rods 152 of the cleaning block 151 move towards the direction close to each other, the cleaning block 151 is driven to move towards the direction far away from the rod body 120, the cleaning block 151 is close to and abutted against the inner wall of the cooling water pipe 500, and when a user operates the washing head 100 to move forwards integrally, the cleaning block 151 can be driven to scrape off or loosen impurities attached to the inner wall of the cooling water pipe 500; in addition, the water sprayed on the push plate 140 is dispersedly sprayed out along the peripheral direction of the push plate 140 and acts on the inner pipe wall of the cooling water pipe 500, so that loose impurities can be washed clean, and the heat exchange effect of the cooling water pipe 500 is improved.

In the present embodiment, the rod 120 is fixed to the connecting tube 110, and specifically, the rod 120 may be fixedly extended from the water outlet end 111 of the connecting tube 110, or may be directly fixed to the outer surface of the connecting tube 110 through a structure such as a mounting bracket. It should be noted that the rod 120 generally extends along the central axis of the connecting tube 110 at least at the water outlet end 111, and the cross-sectional area of the rod 120 is generally smaller than the cross-sectional area of the water outlet end 111 of the connecting tube 110, so as to reduce the influence of the rod 120 on the flow rate of the water ejected from the water outlet end 111. The extension direction of the rod body 120 is substantially parallel to the longitudinal direction of the cooling water pipe 500.

The mounting plate 130 and the push plate 140 are both mounted on the rod body 120, wherein the mounting plate 130 is mounted on the rod body 120 at a position far away from the water outlet end 111 of the connecting tube 110, and the push plate 140 is disposed between the mounting plate 130 and the water outlet end 111 in a reciprocating manner. Specifically, the push plate 140 is movably sleeved on the outer periphery of the rod 120.

The cleaning assembly 150 may be disposed on any lateral surface of the rod 120, taking the cleaning assembly 150 disposed on the upper side of the rod 120 as an example:

two connecting rods 152 are respectively arranged at the front side and the rear side of the cleaning block 151, wherein the front end of the connecting rod 152 at the front side is hinged on the mounting plate 130 in a vertically rotatable manner, and the rear end of the connecting rod 152 at the front side is hinged on the front side wall of the cleaning block 151 in a vertically rotatable manner; the front end of the connecting rod 152 at the rear side is hinged to the rear side wall of the cleaning block 151 to be rotatable up and down, and the rear end of the connecting rod 152 at the rear side is hinged to the push plate 140 to be rotatable up and down.

It can be understood that, referring to fig. 3, when the push plate 140 moves forward, the rear end of the connecting rod 152 located at the rear side can be driven to move forward, so as to link with the other connecting rod 152 to move, and drive the cleaning block 151 to move upward and away from the rod body 120, so that the cleaning block 151 is close to and abuts against the upper inner pipe wall of the cooling water pipe 500, and in the process that the whole flushing head 100 moves forward and backward, the cleaning block 151 and the upper inner pipe wall of the cooling water pipe 500 are driven to generate an interference effect, and the interference effect can cause impurities attached to the upper inner pipe wall to be scraped, loosened or broken.

On the contrary, referring to fig. 2, when the push plate 140 moves backward, the rear end of the connecting rod 152 located at the rear side can be driven to move backward, so as to link the other connecting rod 152 to move, and drive the cleaning block 151 to move downward and close to the rod body 120, so that the cleaning block 151 is far away from the upper inner pipe wall of the cooling water pipe 500, which is beneficial to reducing the overall size of the rinsing head 100, and is more beneficial to the whole forward and backward movement or storage of the rinsing head 100.

It should be noted that the forward movement of the push plate 140 can be driven by the water ejected from the water outlet 111 of the connection pipe 110 under high pressure, and the water ejected under high pressure carries large kinetic energy, so that when acting on the push plate 140 forward, the push plate 140 is driven to move forward enough, and when the water outlet 111 continues to spray water under high pressure, the cleaning block 151 and the inner wall of the cooling water pipe 500 are kept in contact.

Further, in an embodiment, the mounting plate 130 and the push plate 140 are rotatably disposed along a front-back axis, respectively, to drive the cleaning assembly 150 to move along the circumferential direction of the cooling water pipe 500. When the cleaning assembly 150 moves along the circumferential direction of the cooling water pipe 500, that is, the cleaning block 151 can slide along the circumferential direction of the cooling water pipe 500 to abut against the cleaning block, and the cleaning head 100 can move back and forth integrally, so that the cleaning block 151 can walk along a spiral track relative to the inner wall of the cooling water pipe 500, which is helpful for enlarging the action area of the single cleaning block 151 and is helpful for efficiently cleaning impurities attached to the inner wall of the cooling water pipe 500.

Specifically, the mounting plate 130 and the push plate 140 can be driven by an additional driving part, but in this embodiment, referring to fig. 2, 3 and 5, the push plate 140 is in a shape of a disk, and a plurality of protrusions 141 are protruded along the circumferential direction of the outer side of the push plate 140 at intervals; the flushing head 100 further comprises a branch pipe 160, one end of the branch pipe 160 is connected with the connecting pipe 110, the other end of the branch pipe 160 is arranged on the periphery of the push plate 140, and the branch pipe 160 is used for spraying the water body in the connecting pipe 110 towards the convex part 141 at high pressure so as to drive the push plate 140 to rotate along the front-back axis.

It is understood that a plurality of the protrusions 141 may be arranged at intervals in the circumferential direction of the push plate 140; the water inlet of the branch pipe 160 is communicated with the side of the connection pipe 110, and the water outlet of the branch pipe 160 is arranged toward the convex part 141; it should be noted that the direction of the water outlet of the branch pipe 160 needs to be set at a proper angle, so that the branch pipe 160 can spray water at high pressure along the circumferential direction of the push plate 140, and thus can apply an acting force along the circumferential direction of the push plate 140 to each protrusion 141, and can drive the push plate 140 to rotate.

The push plate 140 rotates to a certain extent, which is enough to drive the cleaning block 151 to rotate within a certain angle range; however, in order to increase the rotational freedom of the cleaning block 151, in one embodiment, the push plate 140 can be coupled to the mounting plate 130 in a circumferential direction; alternatively, the hinge between the connecting rod 152 and the mounting plate 130 may be slidably disposed along the circumferential direction of the mounting plate 130, for example, by matching an annular sliding groove with a sliding protrusion.

In addition, referring to fig. 4, in an embodiment, the cleaning block 151 includes a block body 151a and an elastic protrusion 151b disposed on a side of the block body 151a opposite to the rod 120; a plurality of elastic protrusions 151b are dispersedly disposed on the block body 151 a. It can be understood that the elastic protrusions 151b are protruded from the block-shaped bodies 151a to increase the surface roughness of the side surfaces of the block-shaped bodies 151a facing the inner wall of the cooling water pipe 500, so that the interference amount at the abutting position of the cleaning blocks 151 and the inner wall of the cooling water pipe 500 can be increased when the cleaning blocks 151 are slidably abutted against the inner wall, and the impurities attached to the inner wall can be easily detached or loosened. The elastic protrusions 151b are elastically arranged, so that the cleaning block 151 and the inner pipe wall can be flexibly abutted, the cleaning block 151 and the cooling water pipe 500 can be protected from being damaged, and noise can be reduced. The elastic protrusions 151b are provided in a plurality of distributed manner on the block body 151a, so that the contact area between the cleaning block 151 and the inner wall of the cooling water pipe 500 can be increased.

Further, in an embodiment, the elastic protrusions 151b are arranged side by side in a front-back direction, and each of the elastic protrusions 151b extends along a circumferential direction of the rod 120. The plurality of elastic protrusions 151b are arranged side by side in the front-rear direction such that a sufficiently large interference area is provided between the cleaning block 151 and the inner pipe wall of the cooling water pipe 500 when the rinsing head 100 is moved in the front-rear direction as a whole; each elastic protrusion 151b extends along the circumferential direction of the rod body 120, and the groove defined between every two adjacent elastic protrusions 151b extends along the circumferential direction of the rod body 120, so that when the elastic protrusions 151b fall off impurities attached to the inner pipe wall of the cooling water pipe 500, the impurities can be sent out from the extending direction of the groove, and the impurities are prevented from being accumulated on the cleaning block 151 to affect the cleaning effect of the cleaning block 151.

In view of any of the above or below embodiments, the cleaning assembly 150 is disposed at intervals along the circumference of the rod 120. In this way, it is facilitated to enlarge the cleaning action region in the circumferential direction of the inner pipe wall of the cooling water pipe 500, so that the foreign substances adhering to the inner pipe wall of the cooling water pipe 500 can be more efficiently and more thoroughly cleaned.

Further, in an embodiment, at least some of the cleaning blocks 151 of the plurality of cleaning assemblies 150 are arranged in a staggered manner in the front-back direction. Thus, it is helpful to enlarge a cleaning action region in the length direction of the inner wall of the cooling water pipe 500, so that impurities adhering to the inner wall of the cooling water pipe 500 can be more efficiently and more thoroughly cleaned. Especially, when the cleaning block 151 is movable in the circumferential direction of the cooling water pipe 500, a plurality of spiral cleaning tracks can be formed on the inner wall of the cooling water pipe 500, which helps to further optimize the cleaning effect of the cleaning block 151.

Referring to fig. 2, 3 and 5, in an embodiment, the push plate 140 includes a first plate segment 140a and a second plate segment 140b sequentially connected from a middle portion to a peripheral edge thereof; the first plate segment 140a is disposed toward the water outlet end 111, and the second plate segment 140b extends toward the front in a direction away from the first plate segment 140 a. It can be understood that the first plate segment 140a is disposed toward the water outlet end 111, so as to increase the acting area between the water body ejected at high pressure through the water outlet end 111 and the push plate 140 as much as possible, and ensure that the water body ejected at high pressure exerts forward thrust on the push plate 140; the second plate segment 140b is inclined and extends forward gradually in a direction away from the first plate segment 140a, so that the water body impacting on the first plate segment 140a can be guided out towards the peripheral direction of the push plate 140, i.e. dispersed towards the inner pipe wall of the cooling water pipe 500, and can wash impurities loosened by the cleaning block 151 under the forward action, thereby facilitating the impurities to fall off quickly.

In addition, in an embodiment, the rinsing head 100 further includes an elastic member 170 elastically extensible and contractible in the front and rear directions, the elastic member 170 is disposed between the mounting plate 130 and the push plate 140, and both ends of the elastic member 170 are respectively connected to the mounting plate 130 and the push plate 140. The elastic member 170 is, for example, a spring, which is sleeved on the outer circumference of the rod 120, and two ends of the spring are respectively connected to the mounting plate 130 and the push plate 140. Thus, the forward movement of the push plate 140 can be driven by the water sprayed from the water outlet end 111 of the connecting tube 110 under high pressure, and the backward movement of the push plate 140 can be driven by the elastic restoring force of the elastic member 170.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the technical solutions of the present invention, which are made by using the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
