The present utility model proposes a lower nozzle, referring to fig. 1 to 4, comprising:

A nozzle 100;

A nozzle 200 connected to the nozzle 100;

The nozzle 200 is provided with a spray hole 210 and a prismatic hole 220, the spray hole 210 is communicated with the inner cavity 110 of the spray pipe 100 so as to be convenient for water to be sprayed out, and the prismatic hole 220 is arranged on one side of the spray hole 210 and is used for fixing a lower spray head during installation.

The nozzle 100 is in a sleeve shape, the length of the nozzle 100 is related to the wall thickness of the toilet bowl, the nozzle 100 can be in a prismatic shape, a truncated cone shape or an irregular shape, the nozzle 100 can be made of stainless steel, aluminum or other metals and alloys, and can be selected according to requirements, preferably, the nozzle 100 in the embodiment is made of a cylindrical sleeve made of PVC (Polyvinyl chloride ) materials.

One end of the spray pipe 100 is connected with a spray nozzle 200, and the spray nozzle 200 is provided with a plurality of spray holes 210 and prismatic holes 220, wherein the shape and the position of the spray holes 210 are not limited by the utility model, and the spray pipe can be a single round hole or an arc hole or a plurality of irregularly-shaped holes which are arranged. The spray holes 210 are communicated with the inner cavity 110 of the spray pipe 100 for emitting water flow, and it is understood that the number and size of the spray holes 210 have a great influence on the flow rate and flow rate of the emitted water flow, and can be set according to practical situations.

The prismatic hole 220 is used to cooperate with a corresponding tool to fix the lower nozzle. For example, in this embodiment, the prismatic hole 220 is a hexagonal hole 220, the hexagonal wrench 800 with a suitable size is inserted into the hexagonal hole 220, and the nozzle 100 cannot be moved even if the hexagonal wrench 800 is fixed, so that the operation of installing the lower nozzle is very simple and convenient, and the hexagonal wrench 800 can be taken out after the installation is completed. The lower spray head is mounted on the toilet in various manners, for example, the lower spray head can be fixed on the toilet in a bonding, clamping or interference fit manner.

As shown in fig. 2, in some embodiments, the inner cavity 110 of the nozzle 100 is provided with a baffle 300, a side surface of the baffle 300, an inner wall of the nozzle 100 and the nozzle 210 enclose a flow channel 400, and water flows through the flow channel 400 and then is emitted from the nozzle 210; the other side of the baffle 300, the inner wall of the spout 100, and the prismatic hole 220 enclose a cavity 500; the flow channel 400 is not in communication with the cavity 500.

One side of the deflector 300, the inner wall of the nozzle 100 and the prismatic hole 220 form a cavity 500 with a single opening, so that water cannot be ejected out of the prismatic hole 220 by copper, the flow speed and flow rate of water ejected from the nozzle 210 are further ensured, and the flushing effect is improved. Therein, it will be appreciated that the enclosed cavity 500 enables the prismatic aperture 220 to be secured by a corresponding tool, thereby securing the entire lower spray head. Preferably, the deflector 300 and the lower nozzle are formed by an integral molding, so that the sealability and structural stability of the entire lower nozzle are better.

As shown in fig. 2, in some embodiments, the inner diameter of the flow channel 400 tapers from an end of the baffle 300 distal from the orifice 210 to the orifice 210.

By properly adjusting the shape or the inclination angle of the deflector 300, the diameter of the flow channel 400 defined by the second surface of the deflector 300, the inner wall of the nozzle 100 and the nozzle 210 is gradually increased from one end of the nozzle 210 to the other end, so that the water flow does not strike the inner wall of the nozzle 200, and can be smoothly emitted from the nozzle 210, the flow velocity of the water flow is faster, and the flushing effect is better. Preferably, the end of the deflector 300 remote from the nozzle 210 is configured in an arc shape, which reduces energy loss when water passes therethrough, and further increases the flow rate of water.

As shown in fig. 1 and 2, in some embodiments, the end of the spout 100 remote from the nozzle 200 is provided with external threads 120, and the diameter of the nozzle 200 is greater than the outer diameter of the spout 100.

By providing external threads 120 on spout 100, a corresponding fastener is conveniently used to threadably couple spout 100. Correspondingly, the diameter of the nozzle 200 is larger than the outer diameter of the spray pipe 100, the whole lower spray head is mushroom-shaped, and the nozzle 200 and the fixing piece can clamp the lower spray head on the closestool. Preferably, because the wall of the toilet is generally not planar, the portion of the nozzle 200 extending beyond the spout 100 may be irregularly shaped, so that the lower jet fits more closely to the toilet, preventing damage to the lower jet and the toilet due to over-tightening of the installation.

As shown in fig. 1, in some embodiments, the edges of the prismatic hole 220 are provided with a number of locating protrusions 230.

Since the lower jet is generally disposed at the bottom of the toilet bowl, it is difficult to observe whether the position of the jet hole 210 is in line with expectations. And the positioning protrusion 230 is provided on the nozzle 200, so that after the installation of the lower spray head is completed, the position of the positioning protrusion 230 can be determined by observation and touch, thereby determining whether the installation of the lower spray head is correct, and optimizing the flushing effect of the toilet bowl. It should be understood that the number and shape of the positioning protrusions 230 are not limited, and all embodiments capable of achieving the same or similar effects are within the scope of the present utility model. Preferably, the positioning protrusions 230 are three in number and uniformly arranged around the prismatic hole 220, wherein two thinner positioning protrusions 230 are arranged on the left and right sides of the prismatic hole 220, and the middle thicker positioning protrusion 230 is arranged above the prismatic hole 220 (on the side far from the spray hole 210).

As shown in fig. 1 and 2, in some embodiments, the orifice 210 is disposed below the axis of the nozzle 200.

The spray hole 210 is arranged below the axis of the spray nozzle 200, so that water flow emitted from the spray hole 210 is closer to the bottom of the toilet, and the flushing effect is better. Preferably, the nozzle 210 is a circular hole, and only one nozzle is used, so that the water flow speed is faster and the siphon effect can be better induced compared with the arc holes in the market.

As shown in FIG. 1, in some embodiments, the orifice 210 is a circular orifice and the diameter of the orifice 210 is between 4mm-7 mm. Compared with crescent spray holes in the prior art, the circular spray holes with the diameter ranging from 4mm to 7mm can enable the water flow speed of the spray holes to be larger, and the flushing effect is better.

According to the technical scheme, the prismatic holes 220 are formed in the lower spray head, so that when the lower spray head is installed, the whole lower spray head can be fixed by inserting corresponding tools into the prismatic holes 220, and at the moment, when the lower spray head is bonded, clamped or screwed on a toilet, the lower spray head cannot move, and the spray holes 210 in the lower spray head can be maintained at the expected positions, so that the installation quality is ensured, and the flushing effect of the toilet is not influenced.

The toilet bowl according to the present utility model further includes a toilet bowl body 600 and any one of the lower spray heads described in the foregoing embodiments, and the specific structure of the lower spray head refers to the foregoing embodiments, and since the toilet bowl in this embodiment adopts all the technical solutions of all the foregoing embodiments, at least all the technical effects brought by the technical solutions of the foregoing embodiments are provided, and will not be described in detail herein.

As shown in fig. 3, in some embodiments, the water flow direction emitted from the jet orifice 210 is parallel to the bottom wall of the toilet bowl of the toilet body 600, and the distance between the jet orifice 210 and the bottom wall of the toilet bowl ranges from 1mm to 3mm. So that the water sprayed from the spray head is substantially adhered to the bottom wall of the toilet body 600, and the bottom wall can be effectively flushed, thereby keeping the toilet clean.

As shown in fig. 3 and 4, in some embodiments, the device further includes an annular mounting member 700, where the annular mounting member 700 includes a plate portion and a barrel portion, and an inner wall of the barrel portion is provided with an internal thread that mates with the lower spray head.

When the lower spray head is installed, the spray pipe 100 of the lower spray head passes through the installation hole on the closestool, so that the inner wall of the spray nozzle 200 is abutted against the side surface of the closestool, then tools such as a hexagonal wrench 800 and the like are used for extending into the prismatic hole 220 of the lower spray head to fix the lower spray head, and then the annular installation piece 700 is screwed to be connected on the lower spray head through threaded fit until the plate part of the annular installation piece 700 is abutted against the other side surface of the closestool, so that the accurate installation of the lower spray head can be completed. The effect of fixing the lower spray head can be achieved through threaded fit between the annular mounting piece 700 and the lower spray head, and the spray head is simple to manufacture and convenient to install.
