Description
Technical Field
[0001] The utility model relates to the field of cleaning products, in particular to a direct-push toilet gun. Background Art
[0002] At present, cleaning gel has become a common product for cleaning squat toilets or toilets due to its own viscosity when adsorbed on the ceramic surface and the ingredients of detergent and fragrance inside it. Cleaning gel needs tools to be squeezed out when used. The Chinese utility model patent with authorization number CN213429855U discloses a toilet cannon, including a sleeve, a limit ring, a push rod and a piston arranged in the sleeve; one end of the sleeve is open, and an extrusion head is formed at the other end, and an extrusion hole is opened in the middle of the extrusion head; the limit ring is fixedly arranged at the open end of the sleeve; the push rod extends into the sleeve through the opening; the outer wall of the push rod is provided with at least one slide groove along the axial direction, and the slide groove includes at least multiple V-shaped grooves connected end to end, and a limit block is provided on the limit ring corresponding to the slide groove; the limit block is arranged in the slide groove and can slide up and down along the slide groove. The sleeve is filled with a gel toilet cleaner. When the push rod is extended into the sleeve, the limit block slides into the V-shaped groove. Since the limit block is fixed, the push rod rotates along the V-shaped groove during the advancement process. Pushing the push rod can drive the piston to move axially along the length direction of the sleeve.
[0003] When the push rod of the utility model toilet gun is pressed, the push rod rotates along the V-shaped groove and pushes the piston to move axially, providing a tool for squeezing out gel. However, due to the end-to-end V-shaped groove setting, not only does the push rod need to rotate while pushing the piston forward during the process of pressing the push rod, the user will be subject to friction from the circumferential rotation of the push rod while applying linear pressing force with his hand, which makes the hand feel uncomfortable. In addition, this reciprocating V-shaped groove may cause the push rod to get stuck at the turning point, which is inconvenient to use. Utility Model Content

[0007] Furthermore, both the first strip-shaped groove and the second strip-shaped groove are rectangular grooves whose longitudinal length is greater than their transverse length.
[0008] Furthermore, an extension line of a horizontal line where the groove wall at the connection between the head and tail of the first strip groove is located passes through one half of the corresponding second strip groove.
[0009] Furthermore, a slot portion is provided on the outer edge of the limiting ring, and the slot portion is provided in the middle of the first protrusion and the second protrusion.

DETAILED DESCRIPTION
[0027] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "left", "right", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0028] The utility model is further described in detail below with reference to the accompanying drawings:
[0029] A direct push toilet gun, such as Figures 1 to 8 As shown, it includes a sleeve 1 and a push rod 2. The bottom of the push rod 2 is connected to a piston 4. The piston 4 is sleeved on the inner wall of the sleeve 1. The top of the sleeve 1 is open and the bottom is set as an extrusion head 11. The extrusion head 11 is provided with an extrusion hole 111. The cleaning gel in the sleeve 1 can be pushed out from the extrusion hole 111 by the piston 4. The main working principle is the same as the utility model No. CN213429855U in the background technology, that is, pressing the push rod 2 pushes the piston 4 to move downward in the sleeve 1, squeezing the cleaning gel between the piston 4 and the extrusion head 11, so that the cleaning gel is squeezed out from the extrusion hole 111, and then sticks to the surface of the toilet. The utility model has been optimized in the specific mechanism, making it more convenient to use, such as Figure 3-Figure 5As shown, the outer surface of the upper part of the sleeve 1 is provided with a positioning rib 113, and the inner surface of the top cover 3 is provided with a positioning groove 31 that can cooperate with the positioning rib 113 to form a limit. The positioning rib 113 and the positioning groove 31 form a positioning to realize the connection and separation of the top cover 3 and the sleeve 1. The length direction part of the push rod 2 is set as a main body 22, and a longitudinal straight line on one side of the main body 22 is provided with a plurality of first strip grooves 221 connected end to end, and a longitudinal straight line on the other side of the main body 22 is axially symmetrical. A plurality of second strip grooves 222 are connected end to end. The first strip grooves 221 and the second strip grooves 222 are staggered with each other in a horizontal position, that is, the groove walls of the first strip grooves 221 and the second strip grooves 222 are horizontally arranged. The top cover 3 is not aligned upward, and the first through cavity 321 and the second through cavity 322 are symmetrically arranged on both sides of the top cover 3. The first protrusion 3011 and the second protrusion 3012 extending outward are symmetrically arranged on both sides of the limiting ring 301. The first protrusion 3011 extends inward to form a first stopper 3021, and the second protrusion 3012 extends inward to form a second stopper 3022. The first protrusion 3011 and the second protrusion 3012 are respectively limited in the first through cavity 321 and the second through cavity 322. When the push rod 2 moves longitudinally, the limiting ring 301 can move left and right to make the first stopper 3021 enter / disengage from the first strip groove 221, while the second stopper 3022 disengages from / enters the second strip groove 222. Specifically, as Figure 6 As shown, when the second stopper 3022 is in the second strip groove 222, the first stopper 3021 is outside the first strip groove 221, and the push rod 2 is pressed until the second stopper 3022 forms a limit with the upper groove wall of the second strip groove 222, preventing the push rod 2 from continuing to move downward. At this time, the extrusion amount of the cleaning gel is the movement stroke of the push rod 2, and the extruded cleaning gel passes through the various patterns or animal shapes of the extrusion hole 111 to form a corresponding shape of gel and stick to the inner wall of the toilet; Figure 7 As shown, if another gel shape needs to be squeezed out, the first protrusion 3011 can be pushed leftward by hand to move the limiting ring 301 leftward until the first stopper 3021 enters the first strip groove 221 and the second stopper 3022 is separated from the second strip groove 222 where it was previously located. At this time, the push rod 2 is pressed until the first stopper 3021 forms a limit with the upper groove wall of the first strip groove 221, thereby squeezing out another cleansing gel. Pushing the first protrusion 3011 or the second protrusion 3012 left and right makes the limiting ring 301 move left and right to match the longitudinal movement of the push rod 2, thereby squeezing out multiple gels continuously.
[0030] In order to ensure the gel extrusion effect, the first strip groove 221 and the second strip groove 222 are preferably rectangular grooves whose longitudinal length is greater than the transverse length. In this way, the left and right movement of the limiting ring 301 and the longitudinal movement of the push rod 2 can ensure sufficient pushing space for the push rod 2, that is, to ensure sufficient extrusion of the cleaning gel. In order to further ensure the gel extrusion effect, it can be further arranged that the extension line of the horizontal line of the groove wall where the head and tail of the first strip groove 221 are connected passes through the corresponding second strip groove 222. Half of the length, that is, the amount of gel extruded each time is half of the length of the rectangular groove at the restricted position. Of course, the most preferred arrangement is that the longitudinal lengths of the first strip groove 221 and the second strip groove 222 are equal, so that the extruded gel is the same.
[0031] In the process of moving the limiting ring 301 left and right by pushing the first protrusion 3011 or the second protrusion 3012, in order to make the left and right movement more accurate, as shown in FIG. Figure 4 , Figure 5 and Figure 8 As shown, a slot portion 331 can be provided on the outer edge of the limit ring 301, and the slot portion 331 is provided in the middle of the first protrusion 3011 and the second protrusion 3012, that is, the front side or the rear side of the limit ring 301, and the slot portion 331 includes two V-shaped first slots 3311 and second slots 3312 that are longitudinally adjacent to each other, and an inverted V-shaped clamping column 3031 is longitudinally provided on the inner side surface of the top cover 3, and the clamping column 3031 can be respectively engaged with the first slot 3311 and the second slot 3312 to form a limit. In order to further ensure the stability of the left and right movement of the limit ring 301, it is preferred to set the slot portions 331 on the limit ring 301 to two axially symmetrically, and set the clamping columns 3031 on the top cover 3 to two. When in use, the first protrusion 3011 is pushed to the left to move the slot portion 331 to the left until the clamping column 3031 enters the bottom of the V-shaped groove of the first clamping groove 3311 to form a limit position, at which time the first stopper 3021 enters the first strip groove 221, and the second stopper 3022 is separated from the second strip groove 222; the second protrusion 3012 is pushed to the right to move the slot portion 331 to the right until the clamping column 3031 enters the bottom of the V-shaped groove of the second clamping groove 3312 to form a limit position, at which time the second stopper 3022 enters the second strip groove 222, and the first stopper 3021 is separated from the first strip groove 221. Figure 8 As shown, the V-shaped design of the first strip groove 221 and the second slot 3312 and the inverted V-shaped design of the clamping column 3031 can make the contact inclined surfaces fit together to produce a limit position. It is worth mentioning that in order to achieve the movement of the two V-shaped grooves through external force, the limit ring 301 or the top cover 3 is required to have a certain plastic deformation space. Therefore, the limit ring 301 or the top cover 3 or both are made of plastic material.
[0032] To prevent the extruded gel from overflowing to other places, the extrusion head 11 of the sleeve 1 extends toward the bottom to form a retaining ring 112 away from the extrusion hole 111. The retaining ring 112 is an annular side wall, and the retaining ring 112 can also provide stable support when the gel adheres to the inner wall of the toilet.
[0033] In order to provide a larger force-bearing area and facilitate the hand to push the push rod 2 , a hand pushing portion 21 may be provided on the push rod 2 , and the diameter of the hand pushing portion 21 is larger than the diameter of the push rod 2 .
[0034] In order to facilitate closing the toilet cannon when not in use, a bottom cover 5 can be provided. The bottom cover 5 can be buckled on the bottom of the retaining ring 112. The bottom cover 5 is provided with a cover edge 51 extending outward, and the cover edge 51 can facilitate hand application.
[0035] From the above description, it can be seen that the above-mentioned embodiment achieves the following technical effects: pushing the first protrusion or the second protrusion drives the limit ring to move left and right to cooperate with the longitudinal movement of the push rod, and when the first block enters the first strip groove to form a limit, the second block disengages from the second strip groove to release the limit, or when the first block disengages from the first strip groove to release the limit, the second block enters the second strip groove to form a limit. The two states of alternation achieve the effect of extruding multiple gels through the extrusion hole. In this process, the push rod only moves in a linear manner and will not produce circumferential rotation, and the cooperation between the strip groove and the block will not cause jamming, which is comfortable and convenient to use.
[0036] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.
