Description

Technical Field

[0001] The present invention belongs to the technical field of toilet covers, and particularly relates to a water-sealing spray gun with a magnet. Background Art

[0002] In the related technical field of toilet covers, the existing mechanical flushing spray gun is a relatively common product on the market. At present, such spray guns generally use an elastic reset member for resetting to seal the water path. However, if the elastic force of the selected elastic reset member is too large, the elastic reset member cannot be fully compressed under low water pressure, resulting in the problem that the spray rod cannot extend in place and the flushing function fails. If the elastic force is too small, there is a significant deficiency, that is, the water path cannot be effectively sealed. In the actual use process, especially in some specific use scenarios, the residual water in the water path will continuously seep out through the spray gun. This phenomenon not only causes waste of water resources, but also makes the surrounding environment humid and breeds bacteria. More importantly, it greatly affects the user experience of customers. Summary of the Invention

[0003] (I) Object of the Invention

[0004] In order to overcome the above deficiencies, the object of the present invention is to provide a water-sealing spray gun with a magnet, so as to solve the technical problems that the existing flushing spray gun can only use the elastic reset method to not fully compress the elastic reset member under low water pressure, resulting in the spray rod not being able to extend in place and the flushing function failing, and at the same time being unable to effectively seal the water path, and the spray gun is prone to water seepage, causing waste of water resources and the surrounding environment being humid and breeding bacteria.

[0005] (II) Technical Solution

[0006] To achieve the above object, the technical solution provided by the present application is as follows:

[0007] A water-sealing spray gun with a magnet, comprising: a spray gun housing, with a first water inlet and a spray rod outlet at both ends respectively, a first magnet chamber arranged in the spray gun housing near the first water inlet, a second water inlet communicating with the first water inlet and the inside of the spray gun housing is opened through the first magnet chamber, a first magnet arranged in the first magnet chamber, a hollow-structured spray rod movably arranged in the spray gun housing, a third water inlet communicating with the second water inlet is opened on the side wall at one end, a water spray port at the other end, a second magnet chamber arranged at one end of the spray rod corresponding to the first magnet chamber, a second magnet arranged in the second magnet chamber and capable of mutually attracting with the first magnet, a plugging member arranged at the top of the second magnet chamber and corresponding to the second water inlet, and an elastic reset member sleeved on the outer side wall of the spray rod, one end abuts against the inner side wall of the spray gun housing, and the other end abuts against the outer side wall of the spray rod;

[0008] By arranging magnets at the first water inlet of the spray gun housing and the top of the spray rod respectively, at the end of the flushing action, the spray rod returns to the closed state under the drive of the elastic reset part, and the sealing part abuts the first water inlet for sealing. At this time, the two magnets are attracted to each other, and the sealing pressure of the sealing part is increased by the attraction of the two magnets. In this way, an elastic reset part with small elastic force can be used. The use of an elastic reset part with small elastic force not only ensures the water sealing effect during non-flushing action, but also ensures that the spray rod can be normally extended into place under low water pressure conditions, so that the flushing function can operate normally, thereby improving the applicability and reliability of the spray gun in different water pressure environments. When the flushing action starts, the water pressure can push the sealing part and the spray rod away from the first water inlet, so that the two magnets are out of the magnetic attraction range, and the spray rod can be fully extended for flushing, thereby realizing flexible switching of the spray gun between the flushing and water sealing states.

[0009] In some embodiments, a guide groove connecting the second water inlet and the third water inlet is opened along the length of the inner side wall of the spray gun housing;

[0010] The setting of the guide groove ensures that water can flow smoothly from the second water inlet to the third water inlet and then enter the spray rod, thereby ensuring the normal water supply of the spray gun and improving the flushing efficiency of the spray gun.

[0011] In some embodiments, the third water inlet is multiple and is arranged circumferentially around the spray bar;

[0012] By providing a plurality of third water inlets which are arranged circumferentially around the spray rod, water can enter the spray rod more evenly, so that the water spraying is more even, thereby improving the flushing effect of the spray gun.

[0013] In some embodiments, a snap-fit ​​groove is provided on one side of the second magnet bin corresponding to the spray rod, and one end of the spray rod corresponding to the second magnet bin protrudes upward to form a convex block embedded in the snap-fit ​​groove;

[0014] The cooperation between the engaging groove and the protrusion makes the connection between the second magnet bin and the spray rod more stable, ensuring the stability of the relative position of the second magnet and the spray rod, thereby ensuring the adsorption effect of the first magnet and the second magnet and the stability of the sealing effect of the sealing member.

[0015] In some embodiments, the first and second magnets are annular structures;

[0016] The first and second magnets of the annular structure can provide a more uniform magnetic field distribution, thereby enhancing the adsorption force between the first magnet and the second magnet, making the sealing of the second water inlet by the sealing member more reliable, and further improving the water sealing performance of the spray gun.

[0017] In some embodiments, the inner side wall of the spray gun housing protrudes inward near the spray rod extension port to form a limiting step that abuts against the outer side wall of the spray rod;

[0018] The setting of the limiting step can limit the movement range of the spray rod, prevent the spray rod from protruding excessively from the spray gun housing during movement, and ensure the structural stability and normal operation of the spray gun.

[0019] In some embodiments, the water spray opening of the spray rod is opened on the side surface of the end portion, and further includes: a cap provided at one end of the spray rod corresponding to the spray rod outlet and having a shape matching that of the spray rod outlet;

[0020] The cap matches the shape of the spray rod outlet, which can further improve the overall sealing performance of the spray gun. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0030] The present invention provides a water-sealed spray gun with magnets, comprising: a spray gun housing 1, a magnet assembly, a spray rod 5 and an elastic reset mechanism. Specifically, the spray gun housing 1 comprises a spray gun cover 102 and a spray gun bracket 101, the spray gun cover 102 and the spray gun bracket 101 are combined with each other, a first water inlet 1021 is provided on the spray gun cover 102, the spray gun bracket 101 is provided with a spray rod extension port, and a first magnet bin 2 is provided near the first water inlet 1021 inside the spray gun bracket 101, and a first magnet 8 is embedded in the bin. A through-type second water inlet 201 is provided in the center of the first magnet bin 2, and the water entering from the first water inlet 1021 flows into the inner cavity of the spray gun housing 1 through the second water inlet 201. Specifically, the spray rod 5 adopts a hollow structure and can slide along the inner cavity of the spray gun housing 1, and a third water inlet 501 is provided on the side wall of one end thereof close to the first magnet bin 2, and a water spray port 502 is provided at the other end. In addition, the spray rod 5 is provided with a second magnet bin 3 at one end corresponding to the first magnet bin 2, and a second magnet 9 with opposite polarity to the first magnet 8 is built therein, and a blocking member 4 (columnar or conical) is installed at the outer top corresponding to the second water inlet 201. A spring is sleeved on the outer wall of the spray rod 5 as an elastic reset member 6, and the two ends of the spring respectively abut against the inner wall of the spray gun housing 1 and the outer wall of the spray rod 5, forming an automatic rebound mechanism.

[0031] Specifically, the diameter of the second magnet bin 3 is smaller than the spray gun housing 1. Preferably, the present application processes a guide groove 1011 along the axial direction on the inner wall of the spray gun housing 1 to increase the water flow velocity and water volume from the second water inlet 201 to the third water inlet 501 of the spray rod 5. Preferably, the third water inlet 501 is multiple and distributed circumferentially. When the water flows out through the guide groove 1011, the water will enter the multiple third water inlets 501 to avoid pressure imbalance caused by local water flow impact. This design not only reduces water flow resistance, but also improves the stability of water flow inside the spray rod 5, ensuring uniform water flow distribution during flushing. Furthermore, multiple circumferential water inlets make the spray rod 5 symmetrical in force, reduce the risk of lateral deviation, and extend the service life of the spray gun.

[0032] Preferably, the first magnet 8 and the second magnet 9 are both arranged in an annular shape, and the sealing member 4 is tightly pressed against the edge of the second water inlet 201 by magnetic adsorption in the non-working state. Compared with the traditional pure spring seal, the magnetic attraction can greatly enhance the sealing pressure, and reliable water sealing can be achieved even if the spring elastic force is relatively small. When the water pressure pushes the spray rod 5 to extend, the two magnets gradually leave the adsorption range, and the sealing member 4 moves with the spray rod 5 to open the first water inlet 1021. At this time, the water flow can smoothly enter the spray rod 5 to complete the flushing. After the flushing is completed, the dual effects of the elastic reset member 6 and the magnetic attraction enable the sealing member 4 to return to its position quickly, completely blocking the leakage of residual water.

[0033] Specifically, the spray rod extension port matches the diameter of the spray rod 5 to prevent water from leaking outwards.

[0034] Specifically, the first magnet bin 2 is fixed inside the spray gun housing 1 by interference fit or other means such as bonding. Preferably, in this application, a snap - fit connection is adopted between the spray rod 5 and the second magnet bin 3. A U - shaped snap - fit groove is provided on the bottom surface of the second magnet bin 3, and a matching convex block is machined at the end of the spray rod 5. This mechanical interlock design can prevent relative rotation or axial displacement between the second magnet bin 3 and the spray rod 5, ensuring the alignment accuracy of the first magnet 8 and the second magnet 9 and the consistency of the movement track of the plugging member 4. In addition, an annular limiting step 1012 is provided inside the spray gun housing 1 at the spray rod outlet. When the spray rod 5 extends to the maximum stroke, its outer wall contacts the limiting step 1012 to prevent the spray rod 5 from coming out.

[0035] Specifically, the water outlet 502 of the spray rod 5 adopts a side - opening design, and a cap 7 that fits the shape of the spray rod outlet is installed at the end. When the spray rod 5 is fully retracted, the cap 7 and the spray rod outlet form a secondary sealing interface, cooperating with the magnetic attraction seal to achieve double anti - leakage protection. The edge of the cap 7 is made of soft rubber material, which can not only adapt to minor deformations to improve the sealing performance but also buffer the impact noise when the spray rod 5 resets. This structure is particularly suitable for the bathroom environment and effectively prevents the intrusion of humid water vapor into the spray gun, causing corrosion of parts.

[0036] It should be understood that the above - mentioned specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modification examples that fall within the scope and boundaries of the appended claims or equivalent forms of such scope and boundaries.
