Description

Technical Field

[0001] The utility model relates to the field of skin flushing equipment, and specifically designs an injection-type flushing head handle which is easy to process. Background Art

[0002] Skin flushing equipment usually includes a body and a handle installed on the side of the body for the operator to operate. The handle structures of flushing equipment with different functions are different.

[0003] A syringe-type flushing head handle is currently available, comprising a combined handle housing. The housing encloses a telescopic motor positioned horizontally in front and back. A guide rail is provided in the middle and rear portion of the housing's top wall. A slider is mounted in the guide rail. The slider's bottom extends through the housing's top wall and into the interior of the housing. The slider is fixedly mounted on the telescopic rod of the telescopic motor. The telescopic motor controls the telescopic rod to extend and retract, driving the slider forward and backward along the guide rail. An upwardly extending U-shaped clamping mount is integrally formed in the middle portion of the housing's top wall. The clamping mount removably holds a syringe positioned horizontally in front and back. The syringe's injection chamber is filled with a flushing fluid such as essence water. The syringe has a liquid outlet at the front end, communicating with the injection chamber, and a liquid filling port at the rear end, communicating with the injection chamber. A piston push rod is mounted at the liquid filling port, extending rearward above the guide rail. Driven by the telescopic motor, the slider moves forward along the guide rail, driving the piston push rod forward to push flushing fluid in the syringe's injection chamber toward the syringe's liquid outlet for discharge. An upwardly extending stopper mount is integrally formed in the front portion of the housing's top wall. The injection head is removably mounted in the stopper mount. The front and back ends of the injection head are connected, with the back end aligned with and connected to the syringe's outlet. After exiting the syringe's outlet, the irrigating fluid flows through the back end of the injection head to the front end, ultimately being injected through the front end into the skin to be irrigated. The outer shell of this type of irrigating head handle is complex and inconvenient to manufacture. Once molded, the fixed mounting bracket can only accommodate injection heads of the corresponding size; other sizes cannot be accommodated. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an injection type flushing head handle. On the one hand, the shell of the handle is convenient to process, and on the other hand, the shell can be installed with injection heads of other sizes.

[0005] In order to solve the above problems, the utility model provides an injection-type flushing head handle that is easy to process. The handle comprises a shell, on which a mounting seat for mounting the injection head is provided. The mounting seat is detachably mounted on the shell.

[0006] Furthermore, a mounting cavity with an opening facing upward is opened on the top of the shell, and the mounting seat is detachably mounted and accommodated in the mounting cavity.

[0007] Furthermore, the housing is composed of a left shell and a right shell that are detachably assembled and installed, wherein the front top of the left shell is partially recessed to form the left half of the installation cavity, and the front top of the right shell is partially recessed to form the right half of the installation cavity.

[0008] Furthermore, one of the installation cavity and the installation seat is provided with a transverse limiting block and the other is provided with a limiting groove, and the limiting block is engaged in the limiting groove to limit the installation seat accommodated in the installation cavity.

[0009] Furthermore: there are two limit blocks, one on the left and one on the right, symmetrically arranged on the left and right walls of the installation cavity; there are correspondingly two limit slots, one on the left and one on the right, opened on the left and right side walls of the installation seat.

[0010] Furthermore: the mounting seat is provided with a vertical mounting groove; including the injection head, the injection head is vertically inserted into the mounting groove, and is detachably mounted in the mounting seat in this way.

[0011] Furthermore, a fixing seat for fixing the syringe is provided on the shell, and the fixing seat is detachably mounted on the shell.

[0012] Furthermore, one of the fixing seat and the shell is provided with a locking block and the other is provided with an arc-shaped locking groove. The fixing seat moves close to the shell so that the locking block is engaged from the starting end of the arc-shaped locking groove. The fixing seat rotates around the vertical axis to drive the locking block to move along the arc-shaped locking groove to achieve locking.

[0013] Furthermore, the syringe includes the syringe having a hollow injection chamber for accommodating flushing liquid, a liquid outlet connected to the injection chamber is opened at the front end of the syringe, and a liquid filling port connected to the injection chamber is opened at the rear end, and a piston push rod extending backward is installed at the liquid filling port. When the piston push rod moves forward relative to the injection chamber, the flushing liquid in the injection chamber is pushed to the liquid outlet of the syringe for discharge.

[0014] Furthermore, the fixing seat is located behind the mounting seat and includes the injection head, the front end and the rear end of the injection head are connected, the front end is used to flush the human body and the rear end is aligned with and connected to the liquid outlet of the syringe.

[0015] Beneficial effect: The mounting base is installed on the shell in a detachable manner. On the one hand, unlike the background technology in which the mounting base is integrally formed on the shell body, the processing is more convenient. On the other hand, if injection heads of other sizes are to be installed, the operator can first remove the mounting base installed on the shell, and then install the mounting base of other sizes on the shell, and then the injection heads of other sizes can be installed on the replaced matching mounting base.

DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with specific embodiments.

[0028] Injection type flushing head handle 1 Figure 1Above the housing 2, from front to back, are a mounting base 3, a fixing base 4, and a slider 9. An injection head 5 is mounted in the mounting base 3, while a syringe 6 is fixed in the fixing base 4. Syringe 6 is filled with a flushing fluid, which is first injected from syringe 6 into injection head 5 under the push of slider 9, and then injected from injection head 5 into the area to be flushed on the human body.

[0029] The housing 2 is composed of a left housing 21 and a right housing 22. Figure 2 and Figure 3 A T-shaped locking block 23 is provided on the top of the housing 2. The left portion 231 of the locking block 23 is located at the upper edge of the left housing 21 and the right portion 232 is located at the upper edge of the right housing 22. Figure 9 The fixing base 4 is U-shaped, with two symmetrical arc-shaped locking grooves 41 on the bottom surface, and the starting ends 411 of the locking grooves 41 are open. After the two ends of the T-shaped locking block 23 are aligned with the openings of the starting ends 411 of the two locking grooves 41, the fixing base 4 moves downward close to the housing 2 so that the two ends of the locking block 23 are respectively snapped into the openings of the starting ends 411 of the two aligned locking grooves 41; after the snapping is completed, the fixing base 4 rotates forward around its own vertical axis to move the locking block 23 along the arc-shaped locking groove 41. After the two ends of the locking block 23 move to the ends 412 of the arc-shaped locking groove 41, the locking block 23 is locked by the locking groove 41, and the fixing base 4 is thereby installed on the upper part of the housing 2, as shown in FIG. Figure 1 As shown. Since the left portion 231 of the locking block 23 (see Figure 3 ) is provided on the left housing 21 and the right portion 232 (see Figure 3 ) is provided on the right housing 22. When the locking block 23 is locked by the locking groove 41, the assembled left and right housings 21 and 22 are locked and installed together. In this embodiment, the T-shaped locking block 23 serves as the locking portion of the housing 2 and is provided at the top of the housing 2, while the two arc-shaped locking grooves 41 serve as the locking portion of the fixing base 4 and are provided at the bottom of the fixing base 4. In other embodiments, the locking portion can be replaced by the locking block 23 and the locking portion can be correspondingly replaced by the locking groove 41. The locking block 23 can be replaced by an L-shaped locking block 23, and the locking groove 41 can be correspondingly replaced by a linear locking groove 41. The locking block 23 and the locking groove 41 achieve locking by relative lateral movement.

[0030] See Figure 5 and Figure 7 The bottom surface of the housing 2 is provided with a wire groove 24 in the front-to-back direction. The left housing 21 forms the left half 241 of the wire groove 24, while the right housing 22 forms the right half 242 of the wire groove 24. When the left and right housings 21 and 22 are assembled, the left and right halves 241 and 242 together form the wire groove 24. The wire groove 24 has a downward notch, and the bottom of the groove has four groups of mounting holes 25, which are arranged at intervals along the wire groove 24. Figure 7Each group of mounting holes 25 includes a vertical mounting through hole 251 and a vertical mounting screw hole 252; in the same group of mounting holes 25, the mounting through hole 251 and the mounting screw hole 252 correspond to each other, one of which is opened on the left shell 21 and the other is opened on the right shell 22. Specifically: Figure 7 In the first set of mounting holes 25, starting from the front end of the housing 2 and moving backward, the mounting through-holes 251 are located on the left housing 21, while the mounting screw holes 252 are located on the right housing 22. The second set of mounting holes 25 is the opposite, with the mounting through-holes 251 located on the right housing 22 and the mounting screw holes 252 located on the left housing 21. The third set of mounting holes 25 is identical to the first set of mounting holes 25, while the fourth set of mounting holes 25 is identical to the second set of mounting holes 25. When the left and right housings 21 and 22 are assembled, the mounting through-holes 251 and mounting screw holes 252 of the same set are vertically aligned. A bolt (not shown) is inserted into and accommodated in each mounting through-hole 251. Tightening the four bolts in the four vertically aligned mounting screw holes 252 further secures the already locked and assembled left and right housings 21 and 22.

[0031] As described above, the left and right housings 21 and 22 are securely mounted together by locking the tops with the locking block 23 and locking slot 41 and securing the bottoms with four bolts. This eliminates the need for separately providing transverse mounting holes 25 on the left and right housings 22 for locking, as in the prior art. Because the four sets of mounting holes 25 are all located at the bottoms of the wire slots 24, they are not exposed on the sidewalls of the housings 21 and 22, preserving the aesthetic appeal of the housing 2. To disassemble the housing 2, the four bolts are loosened to allow them to exit from the mounting screw holes 252. The fixing base 4 is then rotated in the opposite direction about its vertical axis, causing the locking block 23 to move from the end 412 of the arc-shaped locking slot 41 to the beginning 411 of the arc-shaped locking slot 41. The fixing base 4 is then lifted upward to allow the locking block 23 to exit from the opening at the beginning 411 of the arc-shaped locking slot 41. At this point, the left and right housings 21 and 22 are no longer locked, completing disassembly.

[0032] See Figure 4 and Figure 8, a mounting cavity 26 with an upward opening is provided on the top of the shell 2, wherein the front top of the left shell 21 is partially recessed to form the left half 261 of the mounting cavity 26, and the front top of the right shell 22 is partially recessed to form the right half 262 of the mounting cavity 26. Two left and right horizontal limit blocks 27 are symmetrically arranged on the left and right walls of the mounting cavity 26, one on the left and one on the right; two limit grooves 31 are provided on the left and right side walls of the mounting seat 3, one on the left and one on the right. When the left shell 21 and the right shell 22 are not completely assembled, the operator puts the mounting seat 3 into the mounting cavity 26 and aligns the two limit blocks 27 with the two limit grooves 31 respectively, and then assembles the left shell 21 and the right shell 22 together. The two limit blocks 27 are respectively inserted into the two aligned limit grooves 31 to limit the mounting seat 3, and the mounting seat 3 is thereby installed in the mounting cavity 26 of the shell 2, as shown in FIG. Figure 1 As shown, it is located in front of the fixing base 4. When the mounting base 3 needs to be disassembled, the operator needs to first disassemble the assembled left and right housings 21 and 22 as described above. After disassembly, the mounting base 3 can be directly removed from the mounting cavity 26. In this embodiment, two limit blocks 27 are provided on the wall of the mounting cavity 26, and two limit slots 31 are provided on the side walls of the mounting base 3. In other embodiments, the limit blocks 27 can be provided on the side walls of the mounting base 3, and the number can be changed to one or more than two. In this case, the limit slots 31 are correspondingly provided on the wall of the mounting cavity 26, and the number corresponds to the limit blocks 27.

[0033] See Figure 8 , a vertical mounting groove 32 with the notch facing upward is provided on the top of the mounting seat 3; the injection head 5 is vertically inserted into the mounting groove 32, and in this way can be detachably installed in the mounting seat 3. The U-shaped body of the fixing seat 4 is made of elastic material, and can detachably clamp the side wall of the syringe 6 to fix the syringe 6. The syringe 6 has a hollow injection cavity (not shown in the figure) for accommodating the flushing liquid. The front end of the syringe 6 is provided with a liquid outlet 61 connected to the injection cavity, and the rear end is provided with a liquid filling port (not shown in the figure) connected to the injection cavity. A piston push rod 62 extending backward is installed at the liquid filling port. When the piston push rod 62 moves forward relative to the injection cavity, the flushing liquid in the injection cavity is pushed to the liquid outlet 61 of the syringe 6 for discharge. See Figure 6 , a driving motor 7 is installed in the housing 2, and a driving rod 71 of the driving motor 7 extends backward and is fixedly connected to a screw 82 through a coupling 81; a guide groove 28 is opened at the top of the housing 2 behind the fixed seat 4, and the guide groove 28 passes through the housing 2 downward and communicates with the interior of the housing 2. The above-mentioned slider 9 is installed in the guide groove 28, and the upper part of the slider 9 is exposed and the lower part extends into the interior of the housing 2 through the guide groove 28 and is screwed on the screw 82 (combined with Figure 8). When the syringe 6 is mounted on the mounting base 3, the piston push rod 62 of the syringe 6 is located above the guide groove 28, and the driving rod 71 of the driving motor 7 rotates forward around its own axis, driving the screw 82 to rotate forward through the coupling 81, thereby driving the slider 9 to move forward along the guide groove 28 and pushing the piston push rod 62 to move forward, thereby driving the syringe 6 to discharge liquid. After the discharge is completed, the driving rod 71 of the driving motor 7 rotates in the opposite direction around its own axis, driving the screw 82 to rotate in the opposite direction, thereby driving the slider 9 to move backward and reset along the guide groove 28. In this embodiment, the driving motor 7 is used as a driving motor, which drives the slider 9 to move through the screw 82; in other embodiments, the driving motor can be changed to a stepping telescopic motor, and the lower part of the slider 9 is directly mounted on the telescopic rod of the stepping telescopic motor, and is driven by the telescopic rod to move back and forth along the guide groove 28.

[0034] See Figure 8 The front end 51 and rear end 52 of the injection head 5 are connected, and the rear end 52 is aligned with and connected to the liquid outlet 61 of the syringe 6. After the flushing liquid is discharged from the liquid outlet 61 of the syringe 6, it flows to the front end 51 through the rear end 52 of the injection head 5. A water inlet 53 is provided at the lower part of the injection head 5. The water inlet 53 is connected to the front end 51 and the rear end 52 of the injection head 5. The front end of the water supply pipe (not shown in the figure) is connected to the water inlet 53 and the rear end is connected to a water supply pump. Under the action of the water supply pump, clean water flows through the water supply pipe to the water inlet 53 of the injection head 5, and from the water inlet 53 to the space between the front end 51 and the rear end 52 of the injection head 5, where it mixes with the flushing liquid passing through and flows to the front end 51 of the injection head 5. The operator can hold the flushing head handle 1, align the front end 51 of the injection head 5 with the part of the human body to be flushed, and then inject the mixed flushing liquid into the part to be flushed through the injection head 5 for flushing. The injection head 5 belongs to conventional technology, and its internal structure and working principle are not described in detail here. The water supply pipe body can be accommodated in the wire groove 24 on the bottom surface of the shell 2 to avoid hanging outside the handle 1 and affecting the operator's operation. After the water supply pipe body is accommodated in the wire groove 24, the four groups of mounting holes 25 at the bottom of the wire groove 24 can be covered to avoid the mounting holes 25 affecting the appearance.

[0035] Since the mounting base 3 and the fixing base 4 are not integrally formed with the housing 2, but are detachably mounted on the handle 1 housing 2, processing is relatively convenient; in addition, the mounting base 3 and the fixing base 4 of a certain size can only be used to mount the injection head 5 and the syringe 6 of the corresponding size. If an injection head 5 of another size needs to be installed, the operator can first remove the mounting base 3 and the fixing base 4 installed on the housing 2, and install the mounting base 3 and the fixing base 4 of another size on the housing 2, and then install the injection head 5 of another size on the replaced matching mounting base 3 and fixing base 4.

[0036] The above is only an embodiment of the present invention and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the present invention and still fall within the scope of patent protection.
